DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0033] The utility model provides a low-pressure remote valve control device, comprising:

[0034] A housing connected to the valve;

[0035] The screwing module has an output end connected to a hand wheel on the valve, and the screwing module is arranged on the housing;

[0036] The drive module is connected to the screwing module, and the drive module is connected to the power supply module. The working voltage of the power supply module is 24V;

[0037] The control module is connected to the drive module, and the data between the control module and the remote control center is transmitted bidirectionally.

[0038] Specifically, the control device is installed on the valve through a shell, and a screwing module is arranged in the shell. The screwing module is connected to the handwheel. When the power supply module provides 24V low-voltage electricity, the drive module drives the screwing module to move, thereby controlling the valve. In this way, workers do not need to operate manually to avoid contact hazards. In addition, the voltage for driving the valve to rotate is 24V. If a worker touches the valve, there will be no risk of electric shock in a humid environment. In addition, the power supply module and the drive module both receive instructions from the control module, and the control module also receives the operation data of the valve, so that remote control can be realized. After the opening and closing control instructions are issued, the valve can be operated and controlled immediately to ensure the accuracy of the opening and closing timing and improve the control efficiency.

[0039] Optionally, the control module is also connected to the valve via a flow meter.

[0040] Optionally, a limit alarm module is also included, and the limit alarm module is connected to the valve.

[0041] Specifically, a flow meter is set in the valve body of the valve. When the valve is opened and the valve flow is greater than the set threshold, the limit alarm module will sound an alarm and feed back to the remote control center to remind the operator.

[0042] Optionally, the screwing module includes a transmission rod and two mutually meshing bevel gears, one end of the transmission rod is connected to the output end of the driving module, the first bevel gear is sleeved on the other end of the transmission rod, and the second bevel gear is sleeved on the connecting rod of the handwheel.

[0043] Specifically, when the driving module provides torque, the transmission rod rotates, and the transmission rod rotates synchronously with the first bevel gear, and the first bevel gear and the second bevel gear are arranged perpendicular to each other, and the torque transmitted in the horizontal direction is converted into torque transmitted in the vertical direction, thereby driving the connecting rod of the valve to rotate, thereby realizing the opening and closing flow control of the valve. The screwing module has a simple structure and consumes little torque during the transmission process, thereby ensuring stable operation of the device.

[0044] Optionally, the shell is connected to the valve body of the valve through a flange pipe, and the connecting rod passes through the flange pipe.

[0045] Optionally, the first bevel gear and the second bevel gear are detachably connected.

[0046] Specifically, the housing in the control device is sleeved on the outer periphery of the connecting rod of the valve, the top of the valve body of the valve is connected to a flange pipe, the top of the flange pipe is connected to the housing, the middle part of the connecting rod runs through the flange pipe and the housing, the bottom end of the connecting rod is connected to the valve body, and the top end of the connecting rod is connected to the handle, so that the valve provided with the control device can be not only electrically controlled by the screwing module, but also manually controlled by the handle, thereby ensuring the operational stability of the valve. In the screwing module, when the first bevel gear and the second bevel gear are in mutual meshing, the valve can be electrically controlled, and when the power supply module is in a power-off state, the first bevel gear and the second bevel gear are in a separated state, the torque on the transmission rod cannot be transmitted to the second bevel gear, and there will be no current conduction, so that there will be no risk of electric shock when the valve is manually controlled.

[0047] In another embodiment, a first bevel gear is also provided in the screwing module, but the second bevel gear is replaced by a third bevel gear, and the connecting rod is split into a handwheel connecting part and a gear connecting part, the top end of the handwheel connecting part is connected to the handwheel, and the bottom end of the handwheel connecting part is movably provided with a gear connecting part, and the middle part of the gear connecting part is connected to the third bevel gear, and the gear connecting part moves in a vertical direction, and the gear connecting part is connected to the valve body of the valve by a card-engaging connection. Within the vertical moving range of the gear connecting part, the gear connecting part is inserted into the interior of the valve body to ensure that the gear connecting part can always drive the valve body to move. The gear connection part rotates to control the opening and closing flow control of the valve; when the gear connection part moves downward together with the third bevel gear, the third bevel gear meshes with the first bevel gear, so that the opening and closing action of the valve can be controlled by the screwing module. At this time, the gear connection part and the handwheel connection part are in a separated state, so that the handwheel operation of the valve is invalid under the electric control; when the gear connection part moves upward together with the third bevel gear, the third bevel gear and the first bevel gear are separated from each other, but the gear connection part and the handwheel connection part are plugged into each other, so that the opening and closing action of the valve can only be achieved by turning the handwheel. In this way, the screwing module in this embodiment can realize the separation of manual control and electric control, avoiding the conflict between the two opening and closing control methods, thereby causing damage to the parts of the control device.

[0048] Optionally, the screwing module further includes an electromagnet connected to the power supply module, the electromagnet is a power-off type electromagnet, the first bevel gear is movably sleeved on the transmission rod, and a spring is arranged between the first bevel gear and the housing.

[0049] Specifically, a power-off type electromagnet is also provided in the screwing module. When the power-off type electromagnet is energized, the first bevel gear will not be attracted by the electromagnet, so that the first bevel gear is only affected by the elastic force of the spring. When the first bevel gear is pushed in the direction of the second bevel gear, the two bevel gears are in a state of mutual meshing. Under the rotation of the transmission rod, the opening and closing of the valve can be controlled by the screwing module; when the power-off type electromagnet is in a power-off state, the first bevel gear is attracted by the electromagnet, so that the magnetic force of the electromagnet is greater than the elastic force of the spring, and the two bevel gears are converted into a separated state. In this case, the handwheel drives the connecting rod to rotate, and when the second bevel gear rotates synchronously, there is no need to drive the first bevel gear to rotate synchronously, thereby reducing the difficulty of manually controlling the valve.

[0050] Optionally, the power supply module includes a solar photovoltaic panel and a battery, a charging harness is provided between the solar photovoltaic panel and the battery, and both the solar photovoltaic panel and the battery are connected to the drive module via a DC motor.

[0051] Specifically, the power supply module is powered by solar photovoltaic panels, replacing the original AC power supply, which not only reduces the control energy consumption, but also avoids high-voltage leakage in a humid environment when controlling the valve; while ensuring the supply of power to the drive module, the solar photovoltaic panels can also store excess power in the battery, so that when the solar photovoltaic panels cannot generate electricity, the normal operation of the control device is guaranteed.

[0052] Optionally, a reducer is provided between the DC motor and the drive module.

[0053] Specifically, after the DC motor is energized, the kinetic energy is transferred to the reducer, which reduces the speed of the motor and generates a large torque under low-voltage power supply conditions, ensuring normal opening and closing flow control of the valve, eliminating time differences, and achieving precise control.

[0054] Optionally, a 4G communication module is provided in both the control module and the remote control center.

[0055] Specifically, the control device adopts a 4G communication module for communication transmission, and the 4G communication module is set in the programmable control box, with an IoT card insertion interface reserved to support GPRS or 4G card data transmission; two-way data transmission is carried out between the control module and the remote control center to realize remote control and monitoring by operators, realize background management and control, and improve the precise control of the valve.

[0056] Example 1

[0057] like Figure 1 to Figure 2 As shown, the utility model provides a low-pressure remote valve control device, comprising:

[0058] Shell 1, connected to the valve;

[0059] The screwing module, the output end of which is connected to the hand wheel 2 on the valve, is arranged on the housing 1;

[0060] The drive module is connected to the screwing module, and the drive module is connected to the power supply module. The working voltage of the power supply module is 24V;

[0061] The control module is connected to the drive module, and the data between the control module and the remote control center is transmitted bidirectionally.

[0062] In this embodiment, the control module is also connected to the valve via a flow meter.

[0063] In this embodiment, a limit alarm module is also included, and the limit alarm module is connected to the valve.

[0064] In this embodiment, the screwing module includes a transmission rod 3 and two bevel gears meshing with each other, one end of the transmission rod 3 is connected to the output end of the driving module, the first bevel gear 4 is sleeved on the other end of the transmission rod 3, and the second bevel gear 5 is sleeved on the connecting rod 6 of the handwheel 2.

[0065] In this embodiment, the housing 1 is connected to the valve body of the valve through a flange pipe 7 , and the connecting rod 6 passes through the flange pipe 7 and is connected to the valve core 8 .

[0066] In this embodiment, the first bevel gear 4 and the second bevel gear 5 are detachably connected.

[0067] In this embodiment, the screwing module further includes an electromagnet 9 connected to the power supply module. The electromagnet 9 is a power-off type electromagnet. The first bevel gear 4 is movably mounted on the transmission rod 3 . A spring 10 is provided between the first bevel gear 4 and the housing 1 .

[0068] In this embodiment, the power supply module includes a solar photovoltaic panel and a battery, a charging harness is provided between the solar photovoltaic panel and the battery, and both the solar photovoltaic panel and the battery are connected to the drive module through a DC motor.

[0069] In this embodiment, a reducer is arranged between the DC motor and the driving module.

[0070] In this embodiment, both the control module and the remote control center are provided with 4G communication modules.

[0071] In summary, when the control device needs to open the valve, a worker needs to arrive at the site and send a command to the control module through the remote control center. The control module will start the power supply module, generate electrical energy through the power supply module, and energize the electromagnet 9, so that the electromagnet 9 will not generate a magnetic attraction on the first bevel gear 4. Under the action of the spring 10, the first bevel gear 4 is pushed in the direction of approaching the second bevel gear 5, so that the two bevel gears achieve a mutually meshing position relationship. Under the rotation of the transmission rod 3, the torque of the first bevel gear 4 around the horizontal axis is converted into the torque of the second bevel gear 5 around the vertical axis, and finally drives the connecting rod 6 to rotate together with the valve core to realize the opening and closing flow control of the valve. The control process can achieve precise control without inaccurate opening and closing timing.

[0072] Example 2

[0073] like Figures 3 to 6As shown, in this embodiment, the screwing module also includes a third bevel gear 11, the connecting rod includes a handwheel connecting part 12 and a gear connecting part 13, one end of the handwheel connecting part 12 is connected to the handwheel, and the other end of the handwheel connecting part 12 is movably connected to one end of the gear connecting part 13, the third bevel gear 11 is fixed to the middle part of the gear connecting part 13, and the other end of the gear connecting part 13 is connected to the valve body of the valve, and the outer periphery of the other end of the gear connecting part 13 is evenly provided with a plurality of convex teeth 14, and the valve body is provided with a socket 15, and the inner wall of the socket 15 is provided with a groove corresponding to the convex teeth 14, and the middle part of the gear connecting part 13 is circumferentially provided with a slide groove 16, and a slider 17 corresponding to the slide groove 16 is movably provided in the shell. When the power supply module in the control device provides electric energy, the slider 17 and the slide groove 16 are snap-fitted, driving the gear connecting part 13 to move downward, so that the third bevel gear 11 is meshed with the first bevel gear 4, and the handwheel connecting part When the gear connecting part 13 is connected to the handwheel connecting part 12, the convex teeth 14 of the gear connecting part 13 are still in the socket 15 of the valve body, so that the valve opening and closing flow control is realized; when the power supply module in the control device is in the power-off mode, the slider 17 and the slide groove 16 are still in the snap-fitting cooperation, driving the gear connecting part 13 to move upward, so that the third bevel gear 11 and the first bevel gear 4 are switched to the disconnected state, and the gear connecting part 13 is connected to the handwheel connecting part 12. The connection method can be a plug-in connection, and a plurality of snap-fit ​​blocks and snap-fit ​​grooves can be respectively arranged along the circumferential direction between the gear connecting part 13 and the handwheel connecting part 12. After the two are plugged together, a linkage effect can be realized. Since the gear connecting part 13 is connected to the handwheel connecting part 12 when it moves upward, the convex teeth 14 of the gear connecting part 13 are still in the socket 15 of the valve body, so that the valve can be driven to rotate by rotating the handwheel, thereby realizing the opening and closing flow control. The structure in this embodiment allows only one of the remote electric control and manual control to be selected for the flow control of the valve opening and closing, and both cannot control the valve at the same time, so as to avoid misoperation and damage to the control device and the valve. When the control device is powered on, the slider drives the gear connection part to move downward through the slide groove, and when the control device is powered off, the slider drives the gear connection part to move upward through the slide groove. The above operation process can be realized by setting a telescopic cylinder 18. When powered on, the gas in the telescopic cylinder is pumped away by the vacuum pump, so that the piston of the telescopic cylinder 18 descends, thereby driving the slider 18 to move downward. When powered off, the vacuum pump stops running, so that the gas in the telescopic cylinder is retained, so that the piston of the telescopic cylinder 18 rises, thereby driving the slider 17 to move upward.

[0074] Example 3

[0075] like Figures 7 to 9As shown, in this embodiment, a connecting sleeve 25 is slidably provided on the connecting rod 6, and a card block and a card groove are correspondingly provided on the inner wall of the connecting sleeve 25 and the outer wall of the connecting rod 6, so that the two can realize synchronous rotation, and the connecting rod 6 is no longer connected to the hand wheel 2, the hand wheel 2 is connected to one end of the hand wheel connecting rod 26, and the other end of the hand wheel connecting rod 26 is connected to the fourth bevel gear 19, and the fifth bevel gear 20 and the sixth bevel gear 21 are respectively provided at both ends of the connecting sleeve 25, and the operating rod 22 extends from the outside of the housing 1 to the housing Inside the body 1, the end of the operating rod 22 located outside the shell 1 is connected to the switching handle 27, and the end of the operating rod 22 located inside the shell 1 is inserted into the connecting sleeve 25. Under the action of the tension spring 28, the operating rod 22 can be inserted into the upper limit hole 23 or the lower limit hole 24. The upper limit hole 23 and the lower limit hole 24 are opened along the circumference of the connecting rod 6. In this way, after the operating rod 22 is clamped and fixed with the limit hole, the connecting rod 6 can still rotate synchronously with the connecting sleeve 25 and drive the valve core 8 to rotate. When the worker arrives at the site and needs to manually operate the valve, he pulls out the operating rod 22 so that the operating rod 22 is separated from the lower limit hole 24, but the operating rod 22 remains connected to the connecting sleeve 25. Then the operating rod 22 is moved upward, so that the operating rod 22 and the connecting sleeve 25 move upward on the connecting rod 6. When the fifth bevel gear 20 comes into contact with the fourth bevel gear 19, the worker will feel upward resistance and then release the operating rod 22. Under the action of the tension spring 28, the operating rod 22 can be inserted into the upper limit hole 23, thereby fixing the connecting sleeve 25 at the height position of the connecting rod 6. In this way, the worker can drive the handwheel connecting rod 26, the fourth bevel gear 19, the fifth bevel gear 20, the connecting sleeve 25 and the connecting rod 6 to rotate synchronously in turn by turning the handwheel 2. , thus realizing the manual control of the valve; when the worker completes the manual operation, the valve needs to be switched to electric control. First, the operating rod 22 is pulled outward, so that the operating rod 22 is pulled out from the upper limit hole 23, and then the operating rod 22 is moved downward. When the switching handle 27 is felt to be subjected to downward resistance, the switching handle 27 is released. In this way, under the action of the tension spring 28, the operating rod 22 is inserted into the lower limit hole 24. At the same time, the sixth bevel gear 21 is meshed with the first bevel gear 4, and the fifth bevel gear 20 is separated from the fourth bevel gear 19. In this way, after receiving the remote control command, the transmission rod 3 starts to rotate, and in turn drives the first bevel gear 4, the sixth bevel gear 21, the connecting sleeve 25 and the connecting rod 6 to rotate synchronously, thereby realizing the remote electric control of the valve. In addition, a mark is set on the outside of the shell. Through the positional relationship between the mark and the switching handle 27, it can be quickly judged whether the valve is in manual control or electric control mode.

[0076] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
