The present disclosure is related to an energy and air saving pneumatic barrier device, in particular to the technology used in the field of lifting equipment.
Most of the lifting barrier devices and warning devices for parking and traffic control on roadways on the market are composed of electric motors and deceleration mechanisms. Therefore, the motor needs to be started repeatedly for each movement, which causes a waste of electricity, especially when the motor is started instantaneously, the electricity in need is particularly high.
The above descriptions can be found in, for example, TW M558288, entitled “License plate recognition apparatus and license plate recognition fence” and TWM508743, entitled “Parking fee inspection fence device.” The listed conventional arts are the combination of the starter motor and the deceleration device. In addition to the above problems, when the device is applied to medium and large parking lots that hundreds of vehicles enter and exit every day, and the barrier in used also starts the motor hundreds of times for lifting and lowing the barrier, so that the electricity consumption is also very high. Therefore, the electricity bill has become the biggest burden on the parking lots over time. Moreover, the barriers on the market are all consisted of electric motors and reduction gears. Therefore, when it comes to the electricity outage, the barrier will not be able to move up, and causes inconvenience and trouble that the vehicles would be trapped in the parking lot.
The main objective of the present disclosure is to provide a pneumatic barrier device with effect of energy saving and carbon reduction, to improve the disadvantage of the conventional barrier that is driven by a starter motor and a reducer, and the motor and the reducer restart every raise and lower movement with electricity consumption, which will cause waste of electricity and expensive payment of electricity bills. Further, the motor and the reducer could not operate when the electricity outage, so that the barrier device could not raise and down. In order to achieve the above-mentioned objective and effort, the present disclosure provides an energy and air saving pneumatic barrier device including: a pneumatic component, including an air supply chamber, an actuator portion and an electric control portion, the air supply chamber being connected with an air compressor; a shaft component mounted on the actuator portion; two switch components mounted on the actuator portion correspondingly and near the shaft component, and the electric control portion electrically connected with the switch components; a barrier component mounted on one side of the shaft component; wherein the two switch components control the barrier component, and the shaft component raises and lowers the barrier component; a driving component mounted on another side of the shaft component; wherein, the air supply chamber supplies the air to the driving component to operate and control the shaft component.
The described embodiments may be better understood by reference to the following description and the accompanying drawings in which:
Referring to
In order to solve the conventional problem, the present disclosure provides a pneumatic method instead of the original electric power output, and the air is low air pressure, so that it is necessary to use the air compressor 10 to fill the air supply chamber 11 with air first. After the air supply chamber 11 is filled with air and enters the driving component 5 for operating, the driving component 5 drives the shaft component 2 to rotate, so as to raise and lower the barrier component 4 to block and release. During the whole process, only a little electricity is used when the air compressor 10 inflates the air supply chamber 11. As long as the air supply chamber 11 is within the working pressure range, the air compressor 10 is in a stopped state. By using the air supply and transportation to control the lifting and lowering of the barrier component 4 can save electricity and the cost to achieve the effect of energy saving and carbon reduction. During the electricity outage, the electric control portion 13 can provide the operation via the DC battery, and the barrier component 4 can the lifting and lowering, which will not be affected by the electricity outage. Moreover, the air compressor 10 is mainly used with low pressure. For example, when the air supply chamber 11 is set to a pressure of 3KG/CM2˜7KG/CM2 and when the internal pressure is 7KG/CM2, it is enough to provide barrier component 4 for more than 65 operations (one lifting and one lower as one operation). Therefore, it is very suitable for small, medium and large parking lots (parking garages).
Firstly, regarding the pneumatic component 1, the air supply chamber 11 is hollow, and the outer side of the air supply chamber 11 has an outlet valve 111 and an intake valve 112. The outlet valve 111 and the intake valve 112 are connected with the inside space of the air supply chamber 11. The air intake hole seat 112 is connected with the air compressor 10 by a flexible pipe, and the outlet valve 111 will be assembled with the air compressor 10 and communicated with the driving component 5. The air stored in the air supply chamber 11 is supplied to the driving component 5, as shown in
Further, the structure of the pneumatic component 1 can be read in conjunction with
The shaft component 2 includes two shaft bases 21 in an arch-shape, a shaft center 22, a switch 23 and a driving member 24. The two shaft bases 21 are erected on the actuator portion 12 and spaced apart, the switch 23 is in a square shape and located between the two shaft bases 21, and the shaft center 22 passes through the two shaft bases 21 and the switch 23. In order to make the shaft center 22 rotate smoothly, bearings are installed in the two shaft bases 21 respectively, thereby maintaining the smooth rotation of the shaft center 22. Further, one end of the shaft center 22 is connected to the driving member 24, and the other end of the shaft center 22 is connected to the barrier component 4. Moreover, the switch 23 has two touch levers 231, the rotation of the switch 23 drives the two touch levers 231 to move and touch the two switch components 3 in turn (as shown in
The most important connection between the shaft component 2 and the driving component 5 is the driving member 24, including a base portion 241 connected with one end of the shaft center 22 and an adjustment portion 242 connected with the other end of the shaft center 22, wherein, the adjustment portion has a plurality of adjustment holes 2421. Each of the plurality of adjustment holes 2421 can be adjusted movably according to the weight and length of the barrier component 4.
Moreover, a first axis 20 is defined by the planar side of the actuator portion 12, a second axis 30 is defined by the driving member 24, and the first axis 20 and the second axis 30 form an angle from 15 degrees to 45 degrees. Preferably, the angle is 45 degrees. Such angle provides a shorter movement path (displacement) for the barrier component 4 during the pivoting process, and is also the most air-saving and smoothest linear action for the driving component 5 to quickly interlock the barrier component 4, as shown in
The driving component 5 is the main drive core of the present disclosure, the driving component 5 includes a telescopic air pressure member 51, an adjustment shaft 52, a spring 53 and a pivot base 54. The pivot base 54 is mounted on the pneumatic component 1, and the bottom of the telescopic air pressure member 51 is disposed on the pivot base 54, the top of the telescopic air pressure member 51 is pivotally engaged with the end with a plurality of adjustment holes 2421 of the adjustment portion 242, and the adjustment shaft 52 is through the adjustment portion 242 and the telescopic air pressure member 51. Further, one end of the adjusting shaft 52 that is away from the pneumatic component 1 protrudes out of the adjustment portion 242 to form an interlock portion 521 with the telescopic air pressure member 51, and one end of the spring 53 is sleeved on the interlock portion 521, and the other end of the spring 53 is hooked on a rod 541 of the pivot base 54. The telescopic air pressure member 51 expands and contracts by the air supplying and transporting from the air supply chamber, and the adjusting shaft 52 allows the telescopic air pressure member 51 to swing in conjunction with the driving member 24, at the same time pull the spring 53 to elastically store force. During the expansion and contraction of the telescopic air pressure member 51, the pivot base 54 provides the telescopic air pressure member 51 to buffer swing, and the adjusting shaft 52 can be movably assembled with the adjusting portion 242 to adjust the assembly position of the telescopic air pressure member 51. Moreover, as to the spring 53, through the spring 53 and under the elastic tension, the swing of the barrier component 4 can be quickly reset, so that the touch levers 231 can quickly touch the switch component 3 to close the solenoid valve 62. The spring 3 can also provide more stable operation of the shaft component 2 and the barrier component 4, and the shaft component 2 interlocking the barrier component 4 will be less likely to jump or fail to return, as shown in
Lastly, the barrier component 4 includes a pivot block 41, a rod member 42, a transfer piece 43 and a weight block 44. The pivot block 41 is fixedly connected to the shaft center 22, the transfer piece 43 has a U-shape from the longitudinal section, and is assembled with outer surface of the pivot block 41, and the two ends of the transfer piece 43 extend toward both sides of the pivot block 41 respectively, the rod member 42 and the weight block 44 are respectively movably mounted on the two ends of the transfer piece 43. The weight block 44 can be movably assembled on the transfer piece 43. When the shaft center 22 is driven to pivot, the pivoting of the shaft center 22 is accelerated by the weight of the weight block 44 to change the position of the rod member 42, and because of the weight block 44, the telescopic air pressure member 51 can be quickly expanded and contracted, and therefore it saves the air consumption in the air supply chamber 11, as shown in
In addition, the core value of the present disclosure is to achieve the effect of energy saving and air saving. The telescopic air pressure member 51 adopts the design of a single-acting pneumatic element. Further, the air pressure control member 6 is connected to the bottom end of the telescopic air pressure member 51 and is provided with an air inlet portion 511. The air pressure control member 6 includes a communication valve 61 connected to the air inlet portion 511 and two solenoid valves 62. The two solenoid valves 62 are respectively arranged on the left and right sides of the communication valve 61 for the functions of air inlet and outlet.
When the user controls the device to move upward, the signal is activated by the electric control portion 13. When the solenoid valve 62 receives the instruction, the valve is energized to open and allows the air to enter the telescopic air pressure member 51 and lift to the set position. The touch lever 231 is displaced to the switch component 3 for blocking, and the solenoid valve 62 immediately turns off the power supply so that the air no longer enters. When the user controls the device to move downward, the lowing signal is activated by the electric control portion 13. When the solenoid valve 62 receives the instruction, the valve is opened to let the air discharge, and through the speed control valve 64 to decelerate and the air pressure is discharged through the silencer valve 63, then the telescopic rod is lowered and the touch lever 231 cuts off the power supply of the switch component 3, so that the power valve of the solenoid valve 62 is closed again. The two solenoid valves 62 show the intake valve through which the air first passes through the air supply chamber 11 and the outlet valve through which the gas is exhausted through the telescopic air pressure member 51. The communication valve has three connection ports 611, one of which is connected to the air inlet 511, and the two solenoid valves 62 are respectively connected to the other two connecting ports 611; wherein one of the two solenoid valves is further connected to a silencer valve 63 for eliminating the noise of gas discharge and a speed control valve 64 for controlling the speed of the exhaust, as shown in
The air entering the telescopic air pressure piece 51 has to be adjusted first, that is, the working pressure is 2.5˜3KM/CM2, as shown in
Lastly, the electric control portion includes a power supply 132 and a main controller 133, wherein the power supply 132 is electrically connected with the main controller 133 and provides electricity for operation, the two switch components 3 and each of the solenoid valves 62 are electrically connected with the main controller 133. Further, the main controller 133 has a wireless receiving unit 134, and a wireless remote control 8 is provided and wireless connected with the wireless receiving unit 134 to control the main controller 133. Therefore, the user can use the wireless remote control 8 to control the main controller 133, and the main controller 133 controls the on and off of each of the solenoid valves 62, in conjunction with the two touch levers 231 moving and touching the two switch components 3 in turn, the displacement of the rod member 42 is effectively controlled, as shown in
