A monitor can be used to direct a flow of fluid, such as water or firefighting fluid, at a desired target, typically, without the need for the constant presence of an operator. Often, monitors are mounted on mobile equipment, such as trucks, portable stations, or permanent installations. A monitor can be coupled to a fluid source, and the monitor's outlet can be directed toward the desired target. A monitor can be designed to rotate around a vertical axis to provide directional coverage; and portions of the monitor may be designed to pivot about one or more horizontal axes to provide elevation coverage. A size of the monitor, and fluid flow efficiency of the monitor, can be dictated by the type and number of rotational axes.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
An example fluid monitor may comprise a flexible member, such as a flexible fluid conduit, that is fluidly coupled with a stationary base. In this aspect, in one implementation, the flexible conduit may be manipulated by an actuator, where the actuator is coupled to actuator arms that are engaged with the base and the flexible conduit. Further, the flexible member may be coupled with an outlet of a rotation joint of the monitor, in the base. In this way, for example, the flexible conduit may rotate around a vertical axis to adjust for a direction, and the actuator may adjust an elevation of the fluid outlet by adjusting the flexible conduit. By providing a monitor that does not utilize the elevation horizontal axis couplings of typical monitors, the fluid may not need to flow through the extra elbows, thereby providing reduced friction loss and less turbulence.
In one implementation, a monitor can comprise a base configured to fluidly couple with a fluid supply. Further, an outlet member can be configured to direct fluid from an outlet portion of the monitor. Additionally, a non-articulated, first flexible fluid conduit can be fluidly coupled with an outlet end of the base at an inlet end of the first flexible fluid conduit, and can be operably coupled with the outlet member at an outlet end of the first flexible fluid conduit. An actuator can be operably coupled with the base and the outlet member, and can be configured to adjust an outlet position of the first flexible fluid conduit.
To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.
What is disclosed herein may take physical form in certain parts and arrangement of parts, and will be described in detail in this specification and illustrated in the accompanying drawings which form a part hereof and wherein:
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices may be shown in block diagram form in order to facilitate describing the claimed subject matter.
A typical water monitor comprises rotation around a horizontal axis, to adjust for elevation of the fluid flow output, and rotation around a vertical axis, to adjust for the direction of the fluid flow output. One or more portions of a typical water monitor can rotate around a horizontal axis, and one or more portions can rotate around the vertical axis. Further, the outlet of the typical monitor is aligned on a same plane as the vertical axis to mitigate a rotation moment that can be created by the opposing thrust from the water exiting the monitor, which can cause the monitor to rotate around the vertical axis under operation. This alignment arrangement dictates that the typical monitor's water way needs to be curved to create a bearing axis and sealing surfaces. However, respective curves in the waterway create friction loss, which can be overcome by increased pumping capacity, or results in reduced reach of the output water stream. The addition of curves can increase the turbulence of the water stream as it exits the monitor, which can also reduce the reach of the water stream. A fluid monitor system may be devised that can mitigate the number of bends/curves in the fluid way of the monitor, which can improve an amount of friction loss through the monitor, and may reduce potential turbulence of the fluid stream.
In one implementation, an example monitor can use a flexible member (e.g., rubber or polyester hose, stainless steel braided hose, composite, etc.) to connect the positionable outlet of the monitor to an outlet (e.g., ridged) of a rotation joint of the monitor. The flexible member can span the fluid-way across an elevation actuator. In this implementation, the actuator can be positioned with one or more supports, comprising a type of exoskeleton. As an example, the exoskeleton can engage with a rotation member of the monitor. In one implementation, additional degrees of freedom may be provided for the monitor, at the ends of the flexible member (e.g., rotation, axial movement) to mitigate pinching or kinking of the hose, for example, depending upon the degree of elevation implemented for the monitor. In this implementation, in order to provide the extra degrees of freedom, a ball and seal can be disposed on respective ends of the flexible member. Further, in one implementation, on one end of the flexible member, a telescoping member, such as a sliding piston, can be disposed, which may allow the flexible member to slide in and out, for example.
In typical monitors, a horizontal axis is created in order to elevate the outlet of the monitor. Alternatively, some monitors may have two 45 degree joints that work in opposite directions to create an elevation movement. By providing a monitor that does not utilize the elevation horizontal axis, as with typical monitors, the fluid may not need to flow through the extra elbows, thereby providing reduced friction loss.
In one aspect, an exemplary fluid monitor may comprise a member (e.g., rubber or polyester hose, stainless steel braided hose, composite, etc.), such as a flexible fluid conduit, that is fluidly coupled with a stationary base. In this aspect, in one implementation, the flexible conduit may be manipulated by an actuator, where the actuator is coupled to actuator arms that are engaged with the base and the flexible conduit. Further, the flexible member may be coupled with an outlet of a rotation joint of the monitor, in the base. In this way, for example, the flexible conduit may rotate around a vertical axis to adjust for a direction, and the actuator may adjust an elevation of the fluid outlet by adjusting the flexible conduit.
As an illustrative example, in this implementation, the placement of the outlet portion 106 of the monitor can determine a direction of fluid flow from the monitor 100. That is, for example, a direction of fluid flow can be adjusted by rotating the first flexible fluid conduit 108, and therefore the outlet portion 106, around an axis “A” 128 that runs through a center of the base 102. The axis “A” 128 can lie along a direction of fluid flow in the base, which may comprise a vertical axis when the base is mounted on a substantially horizontal surface (e.g., or near horizontal), for example. It should be appreciated that the term vertical axis may be used to refer to the “A” axis 128; however, the “A” axis 128 may not actually always operate, or be disposed, in a vertical orientation.
Further, for example, an elevation of the outlet portion 106 can be adjusted using the actuator 116 to move the location of the outlet member 104 along an arc “B” 130 (e.g., up and down). In this way, for example, the placement of fluid flow output from the monitor 100 can be determined by adjustment around the “A” axis 128 and/or adjustment along the “B” arc 130, using the first flexible fluid conduit 108. In this example, the flexible nature of the first flexible fluid conduit 108 may allow it to be adjusted, such that an elevation of the outlet member 104, and therefore the fluid output, can be adjusted along the “B” arc 130. In one implementation, the moment provided by the adjustment of the elevation (e.g., for outlet member 104), along the arc “B” 130, can have a point of rotation centered approximately at the actuator 116.
In one implementation, the exemplary monitor can comprise a fluid outlet component 134 that is configured to fluidly couple with the base 102 and provide an outlet for fluid from the fluid source 136. In this implementation, the fluid outlet component 134 can comprise the first flexible fluid conduit 108 and the outlet member 104. In one implementation, the first flexible fluid conduit 108 can be monolithically formed, such as from an unjointed piece of flexible material (e.g., rubber or polyester tubing, composite, etc.) to fluidly couple the positionable outlet member 104 of the monitor to the base 102. In one implementation, the flexible fluid conduit 108 can be formed from combining a plurality of pieces into a flexible structure, such as from a braided or seamed/glued material (e.g., stainless steel braided hose, seamed and formed tubing, etc.).
In one implementation, the exemplary monitor can comprise a rotation coupling 132 that couples the base 102 in rotatable engagement with the first flexible fluid conduit 108. In this implementation, for example, the rotation coupling 132 allows the first flexible fluid conduit 108 to be rotated around the “A” axis 128 (e.g., a central longitudinal axis passing through the base), such as to change direction of fluid flow from the outlet portion of the monitor 106. In another implementation, the flexible conduit 108 may couple with the base 102 in a non-rotating engagement, and the base 102 may be configured to rotate around the “A” axis 128. In this implementation, the base may comprise, or be engaged with, a rotation component that provides rotation for the base 102, resulting in rotation of the flexible conduit 108.
In one implementation, as illustrated in
As an illustrative example, the base 102 may be mounted in a stationary position, such as on a vehicle, mounting base, or ground, and coupled to a fluid source 136. In this example, activating the actuator 116 can result in radial movement of the second actuation arm 120, while the first actuation arm 118 remains stationary. The resulting radial movement of the second actuation arm 120 can cause the outlet member 104, and hence the outlet end 114 of the first flexible fluid conduit 108, to move along arc “B” 130 to adjust elevation. It should be appreciated that the first actuation arm 118 may merely comprise a connection between the actuator 116 and the base 102. That is, the actuator 116 may be disposed at the base 102, and the second actuation arm 120 may comprise a structural element disposed between the base 102 and the outlet member 104. Further, in one implementation, the first actuation arm 118 may be coupled with the base 102 in a rotating engagement, for example, such that the first actuation arm 118 is able to rotate around the “A” axis 128 when the first flexible fluid conduit 108 is rotated around the “A” axis 128. In another implementation, the first actuation arm 118 may be coupled with the base 102 in a stationary engagement, for example, such that the first actuation arm 118 rotates around the “A” axis 128 when the base 102 rotates around the “A” axis 128.
In one implementation, as illustrated in
In one implementation, the outlet end of the base 102 can comprise a telescoping member 124 that is operably engaged with the inlet end 112 of the first flexible fluid conduit 108. In this implementation, the base telescoping member 124 can be configured to extend from the outlet end 110 of the base 102 during fluid flow, and can retract into the outlet end 110 of the base 102 during non-fluid flow. As an example, pressure from fluid flowing through the first flexible fluid conduit 108 can result in the first flexible fluid conduit 108 translating in the direction of fluid flow. In this implementation, in this example, the base telescoping engagement 124 allows the inlet end 112 of the first flexible fluid conduit 108 to telescope (e.g., slide) a desired distance out of the outlet end 110 of the base 102.
In one implementation, the desired distance can be determined by a stop engaged with the inlet end 112 of the first flexible fluid conduit 108 that engages with a stop engaged with the outlet end 110 of the base 102. In this way, for example, during fluid flow, the first flexible fluid conduit 108 can extend out of the base 102 at least until the conduit stop meets the base stop. Further, in this example, when fluid flow is terminated, the first flexible fluid conduit 108 can retract back into the base 102. As an example, the base telescoping engagement 124 may comprise the fluid conduit stop, the base extension stop, and a base retraction stop. In this example, the desired distance of travel for the telescoping engagement 124 may comprise a distance between the fluid conduit stop and the base extension stop.
In one implementation, the outlet member 104 can comprise a telescoping engagement 126 with the outlet end 114 of the first flexible fluid conduit 108. In this implementation, the conduit outlet telescoping engagement 126 can be configured to allow the outlet member 104 to extend from the outlet end 114 of the first flexible fluid conduit 108 during fluid flow; and can be configured to allow the outlet member 104 to retract toward the outlet end 114 of the first flexible fluid conduit 108 during non-fluid flow. As an example, during fluid flow, pressurized fluid can cause the outlet member 104 to telescope out from the outlet end 114 of first flexible fluid conduit 108, using the conduit outlet telescoping engagement 126. Further, in this example, in the absence of the pressurized fluid, when fluid flow is terminated, the outlet member 104 can retract back to the outlet end 114 of first flexible fluid conduit 108.
In one aspect, in accordance with the apparatuses and systems described herein, an example monitor can comprise a flexible component, a monitor base, and actuator component, one or more swivels comprising one or more ball components, which may swivel and adjust in complimentary sockets. In one implementation, in this aspect, the flexible member threshold limit on a curve radius of the flexible member, which may designate a failure (e.g., kink, disruptions, etc.) limit for the flexible member. For example, a small threshold radius may result in a large monitor, or may limit a radial elevation along the elevation arc (e.g., horizontal axis), which can reduce the range of operation of the monitor.
In one implementation, in this aspect, as illustrated in
In this implementation, the example monitor 400 can comprise the base 102, the outlet member 104, and the outlet portion of the monitor 106. Further, in this implementation, the example monitor 400 can comprise an alternate fluid outlet component 434. The alternate fluid outlet component 434 can comprise the first flexible fluid conduit 108 and an alternate rotation coupling 450. The alternate rotation coupling 450 can comprise a curved conduit 450 that can be configured to provide fluid coupling between the base 102 and the first flexible fluid conduit 108. Additionally, the curved conduit 450 can comprise a ridged conduit disposed in a curved condition, for example, where the degree of radius of the curve is based at least upon a desired degree of elevation to be provided by the monitor 400.
In this implementation, the alternate rotation coupling 450 can comprise an outlet coupler 454, comprising a first ball coupling, configured to couple with the fluid outlet component 134 to provide rotation for the fluid outlet around a central, longitudinal axis of the base component 102. Further, the alternate rotation coupling 450 can comprise base coupling component 456, comprising a second ball coupling 456, configured to fluidly couple with the outlet coupler 454 in rotational engagement.

In one implementation, the fluid outlet can comprise a non-articulated, flexible fluid conduit (e.g., 108) that is fluidly coupled with the base component, and can be configured to flexibly adjust the fluid outlet component to a plurality of outlet positions. Further, in this implementation, the an actuator (e.g., 116) can be operably coupled with the base component, where the actuator may be configured to adjust the outlet position of the fluid outlet component. Additionally, in this implementation, the actuator can be operably coupled with the fluid outlet component. In one implementation, the coupling of the base component with a fluid outlet component can comprise coupling the fluid outlet component in rotational engagement with the base component, such that the fluid outlet component can rotate around a central, longitudinal axis of the base component.
