BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevation view of the mobile sewer and drainage pipe cleaning utility service vehicle of the present invention wherein the arrangement includes a jetter system to dislodge dirt and debris from a drainage pipe and further includes a vacuum system to remove the dislodged debris and dirt from the drainage pipe and man hole and the present invention is shown to use multiple articulated booms to position the utility servicing hoses and controls within user friendly proximity of a manhole so that an operator has efficient access to the controls, vacuum hose and jetter hose.
FIG. 2 is a top view of an embodiment of the present invention showing a reel supported on the second end of an articulated boom. The reel is shown to have a manually operated swivel base between the reel and the boom. The first end of the boom is shown to be supported by an hourglass worm slew drive which is motor drive. The worm slew drive is shown to be mounted on a mobile vehicle base. The boom and reel are shown to be positioned to the rear of a vehicle and near a manhole. The reel is shown to have a motor attached to it for dispensing or retracting a hose or cable. Sensors are shown to monitor operating parameters such as speed, torque, direction of rotation. Limit switches are shown which can be used to insure positioning of the boom arm.
FIG. 3 is a top view similar to FIG. 2 except that the boom arm is shown to be rotated in order to position the hose reel to the side of the mobile vehicle instead of being behind the vehicle. In this arrangement a man hole located to the side of the vehicle is being accessed by the hose reel. The Hose reel is also shown to be able to swivel on a base on the second end of the boom arm. The boom arm could also be rotated as shown in FIG. 3 for the purpose of clearing the access area to a vacuum tank access door, and the limit switches could be used to verify that the boom and hose reel are clear of a vacuum tank access door. The limit switches could also be used to stop the access door from being opened unless the boom and reel were clear of the vacuum door access area.
FIG. 4 is a top view similar to FIG. 2 wherein FIG. 4 shows an example of adding multiple arms and multiple pivot axes to the boom in order to add additional flexibility to the articulation of a reel. This drawing also shows that multiple pivot axes connections may be upgraded from a simple support and shaft to a worm slew drive with a motor to power the worm drive. However the worm drive could be a simple hand crank.
FIG. 5 is a side view of the concept shown by the plan view of FIG. 4. FIG. 5 shows from a side view, an example of adding multiple arms and multiple pivot axes to the boom for both horizontal and vertical movement in order to add three dimensional movement to positioning the reel. This drawing also shows that multiple pivot axes connections may be upgraded from a simple support and shaft to a worm slew drive with a motor to power the worm drive. However the worm drive could be a simple hand crank.

The pivot able mounting means 302 or pivot able mounting means 305 could be a shaft with a sleeve, a shaft with bearings, a slewing ring gear or the like. For the purpose of illustration, the inventor has chosen to draw a slewing ring gear 303 as a preferred means to pivot ably mount the boom 300 to base 301. The slewing ring gear 303 may be of the model S-9 hourglass worm slew ring gear drive as made by Kinematics Mfg. Inc. or the like. The slew ring gear rotation means 306 may be a manual hand crank, a hydraulic motor, an electric motor, an air motor or the like. In the illustration drawings, the inventor has drawn a motor as an example of the slew ring drive rotation means 306. Boom arm 304 is illustrated as having a first end pivot ably mounted via slewing ring gear 303 to the mobile platform 31 boom base 301. A second end of boom arm 304 is supporting a reel 37. The reel 37 is illustrated as having a pivot able mounted means 305 near a second end of boom arm 304. As illustrated in FIG. 1 the reel 37 mounting base 307 is pivot ably mounted near a second end of boom arm 304 via a slewing ring gear 303 which is rotate able using a motor 306.
As illustrated in FIG. 1, the reel 37 may be used as a hose reel, a cord reel, a cable reel or the like. The Jetter hose reel 37 is illustrated to have pressurized water supplied to it through a water hose 5. A water storage container 8 is mounted on the mobile platform 31. A power plant 76 water pump takes water 2 from the water storage container 8 and pumps the water 2, under pressure, to the jetter hose reel 37 via water hose 5. A jetter hose 58 is shown to transport the pressurized water 2 from the jetter hose reel 37 to a jetter nozzle 39. The jetter nozzle 39 is shown to dispense a first portion of the water 2 backwards (in the direction the jetter hose 58) thus this first portion of the water 2 serves to propel the jetter nozzle 39 and jetter hose 58 forward (like the principle of using a jet engine). This water 2 jet propulsion drives the jetter nozzle 39 forward through the utility conduit 38 and into contact with any obstruction of earthen material 45 which may be clogging the utility conduit 38. A second portion of the water 2 is illustrated to be dispensed forward of the jetter nozzle 39. This second portion of water 2 may be used to erode away earthen material 45 which may be clogging the utility pipe 38. It is best to enter and clean a utility conduit 38 from the down hill end thus the water flows by gravity to a man hole on the down hill end of the utility conduit 38. Another us of the jettered first portion of water 2 is to wash the eroded earthen material 45 out of the utility conduit 38 and into a man hole 59 where the water 2 and earthen material 45 can be vacuumed up by the suction end of vacuum conduit 17.
It is important to monitor and to document most aspects of the inspection, cleaning service and repair operation. It is customary for utility companies to maintain documentation and mapping programs on their utility network. They need to further document all changes made to a utility because each change can have a reactive affect on other parts of the system. Thus data, associated with the inspections, cleaning, and servicing of a utility, needs to be gathered, transmitted and stored in a useful manner in the records of the utility company. FIG. 1 illustrates data gathering, transmitting, storage, monitoring, computing, controlling, and the like, of information associated with the machine's involvement in inspecting, cleaning or servicing a utility.
In FIG. 1 an RFID 313 is illustrated as a part of the present invention for a purpose of having an operator log in before starting to operate the machine. This RFID 313 sign in documents pre required data about who the operator is and denies access to a person not pre approved and trained to operate a function of the machine.
In FIG. 1 a GPS 312 is illustrated as a part of the present invention for a purpose of using the Global Positioning System as a means of documenting the geographic location of a utility, the location that a service was performed, and the date and time a service started, how long it took to perform a service and when the service was completed.
In FIG. 1 a transmitter/receiver 209 is illustrated as a part of the present invention for a purpose of communicating data by wireless transmission.
In FIG. 1 a monitor/controller 34 is illustrated as a part of the present invention for a purpose of placing information and a means to use the data in a user friendly position for an operator. The monitor/controller 34 can be hand held or mounted accessible to the operator via by sight and tough or wirelessly via a remote computer.
In FIG. 1 a hose/cable measuring system 311 is illustrated as a part of the present invention for a purpose of sensing the direction a jetter hose 58 is traveling, the speed it is traveling at and the distance it has traveled. In other examples of the present invention the hose/cable measuring system will work similar to sense measuring parameters of a power cord, fiber optic cable, air hose, cable, or the like.
In FIG. 2 a monitored, power means of dispensing or retrieving a hose or cable from reel 37, is illustrated as a part of the present invention. A motor 311 is illustrated as being a means to turn reel 37. The motor 311 could be an electric motor, a hydraulic motor or the like. 315 is illustrated as an energy source line to motor 311. Sensors are illustrated to determine one or more parameters associated to the operation of reel 37. Examples of the sensors are illustrated as a rotation sensor 314 which may detect the direction of rotation, speed of rotation or number of rotations. Torque sensor 316 may sense the pressure, temperature and or flow of hydraulic fluid through a hydraulic line 315 to a hydraulic motor 311. Torque sensor 316 may sense the voltage and or amperage of electricity going through power cord 315 to an electric motor 311.
FIG. 2 illustrates that the articulated boom 300 can pivot a reel 37 horizontally to a position at the rear of a mobile vehicle 31. (Note: mobile platform 31 can have one or more boom mounting base 301 at the front and or side of a vehicle, depending on a users preference of use.) Positioning sensors 310 can inform an operator of the degree of rotation the boom arm 304 is at. The position sensor 310 can also limit the degree of rotation of boom arm 304. The position sensor 310 can also restrict an access door 18 from opening if the boom 300 or reel 37 is in the way of opening access door 18, and the like.
FIG. 3 illustrates the present invention's use of boom 300 to move the reel 37 into a used friendly relation to a man hole 59, wither the man hole 59 is behind or to either side of mobile vehicle 31.
FIG. 4 illustrates the present invention's use of multiple boor arms 304 and multiple pivot able mounting means 302 in order to give additional articulation to the positioning of reel 37 in relation to a work area, man hole or the like.
FIG. 5 illustrates the present invention's use of multiple boom arms 304 and multiple mounting means 302 being oriented in both a horizontal and a vertical position in order to give even more articulation to the positioning of reel 37 in relation to a work area, man hole or the like.
FIG. 6 illustrates the present invention's use of two or more reels 37 placed simultaneously near a man hole, work area, or the like. Each reel 37 may have a different function. For example, one reel 37 may use a jetter hose 58 to clean a clog of earthen material 45 from a drain pipe 38 and a second reel 37 may have a fiber optic cable 310 to power and get pictures from a camera 325 which documents the condition of drain pipe 38.
As illustrated in FIGS. 7, 8 & 9, boom 300 has an out rigger 320 adding additional support and stability to the second end of boom arm 300. Outrigger 320 is illustrated to have a foot 322 attached. The outrigger 320 could be in the form of a stiff leg, a tripod, a powered side arm similar in function to that of a back hoe or crane, or the like. The foot 322 is a base used to grip and or support out rigger 320 against a firm foundation. A guide 321 is illustrated as a means to protect or align the likes of a cable 328 or jetter hose 58 while entering or exiting a man hole. The outrigger 320 may also have an attached, extension to support a guide roller 323. Guide roller 323 assist to stabilize the likes of a cable 328 or jetter hose 58 while entering or exiting a man hole lateral line.
FIG. 7 illustrates the present invention using a boom 300 to support a reel 37. FIG. 7 illustrates yet another use for the reel 37. In FIG. 7, reel 37 is illustrated as being used as a wench to pull a wedge 324 through a lateral line 38 using a cable 328.
FIG. 7 is yet another aspect of the present invention. For example: FIG. 1 illustrates the present invention jettering 39 debris 45 from a drainage pipe 38. In some cases it is efficient to also attach a cable 328 along side the jetter hose 58 and use the jetter nozzle 39 for cleaning a hole through the clogging dirt 45 while simultaneously pulling a length of attached cable 328 through the pierced clearance hole in the clog 45. After a second end of the cable 328 has been pulled through a hole in the clog 45, a wedge 324 attached to the second end of the cable 328 can be pulled back thought the clog 45. Reel 37 serves as a winch by rolling up a first end of the cable 328.
The wedge 324 could be attached to the second end of cable 328 at a second man hole 59 upstream from the clog 45, or the wedge 324 could be of a collapsible design which collapses or flattens when being pulled by the jetter nozzle 39 and expands into an enlarged wedge when pulled in the reverse direction by a second end of a jetter hose 58 or a cable 328 which may also be an umbilical cord which is defined for the purpose of this patent as a combination of two or more types of flex able elongated objects working together for a common purpose such as a jetter hose 58 combined with a cable. When the wedge 324 is being pulled by a second end of cable 328 through a clog 45 in a drain pipe 38, the wedge 324 may also have jetter nozzles 39 spraying water 2. Placing the jetter nozzle 39 on the wedge 423 also places the pressurized water 2 closer to the wall of a sewer or drainage pipe 38, thus the pressure of the water 2 impinging the inside wall of the pipe 38 is greater thus, larger pipes 38 can be cleaned with lesser volumes of water 2 and at lower pressures. The wedge 324 can be expanded or collapsed using a fluid like water 2 or air or mechanically using a hinge arrangement.
FIG. 7B illustrates the wedge 324 in a collapsed and flattened configuration as it is being pulled by a jetter nozzle 39.
FIG. 8 illustrates reel 37 supplying a power, electronic and fiber optic cord 310 having a camera 325 attached and moved through a pipe 38 to observe the condition of the pipe 38. In this example the camera 325 has the ability to pictures of the conditions and to take digital measurements of repair areas 327. Camera 325 can be a digital camera, a video camera, a CMOS camera, a CCD camera that use time of flight principals to measure the size and position of items or the like. Wave lengths 326 are used in monitoring the condition of a repair area 327. Data from sending and receiving wave lengths 326 is transmitted back to data loggers and computers for analysis, and use to prepare for a next phase of the service work.
FIG. 9 illustrates reel 37 having the first end of cable 330 attached to reel 37 and a second end of cable 330 attached to an inflatable base 401 and said cable 330 is a multi functional umbilical cord having ability to supply air, power, electronic, air craft cable and fiber optics to an inflatable base 401, having a first end of an articulated robotic arm 402 attached to the inflatable base 401. A second end of the articulated robotic arm 402 is illustrated as having an attachment means to support surface preparation tools 403. A surface preparation tool 403 can be chosen from an abrasive disc, a sand blaster, a water/sand blaster, a laser, a hand, a heat gun, or the like. The articulated robotic arm 402 may be powered and remotely operated. The arm 402 is used in conjunction with the inflatable base 401 and the tool attachment means 403 in order to fix a repair area 327. 404 represents water, sand, air or heat being directed toward repair area 327 in order to repair a damaged pipe 38. The inflatable base 401 becomes stable when inflated against the wall of a pipe 38. Inflatable base 401 is also shown to serve as a mounting platform for a camera 325. The camera 325 is able to be remotely controlled in order to visualize the work area 327.
