Description

Technical Field

[0001] This invention relates to the field of well-electric dual-control product manufacturing technology, specifically to a well-electric dual-control water testing production line and water testing method. Background Technology

[0002] To facilitate water consumption statistics, existing groundwater wells are equipped with dual-control devices for both water usage and on-site control. These dual-control products require trial water testing during production to check for leaks or other defects.

[0003] The well-electric dual-control product requires internal components such as flow metering modules and communication modules to be housed in a molded enclosure, and also needs to undergo water testing and communication debugging. In traditional production, each process is completed in different workshops, resulting in frequent transportation of semi-finished products and low production efficiency.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0005] The main objective of this invention is to provide a well-electric dual-control water testing production line and water testing method, which solves the problem of low production efficiency of well-electric dual-control products mentioned in the background art.

[0006] To achieve the above objectives, the solution of the present invention is:

[0007] A well-electric dual-control water testing production line includes a water testing machine; it also includes a first conveyor line and a second conveyor line located before and after the water testing machine; the well-electric dual-control product is conveyed on the first conveyor line and the second conveyor line; a first installation station is provided on the side of the first conveyor line for installing a flow metering device inside the well-electric dual-control product, the flow metering device is installed between the upper and lower connectors of the well-electric dual-control product and is located inside the well-electric dual-control product.

[0008] The test water machine includes a hydraulic lifting device, an upper pressure head, and a floating base. The hydraulic lifting device includes a base, a guide column, a movable plate, and a hydraulic cylinder. The guide column is mounted on the base, and the upper end of the movable plate is connected to the hydraulic cylinder and can move along the guide column under the drive of the hydraulic cylinder. The upper pressure head is mounted on the lower surface of the movable plate, and an exhaust channel is formed inside the upper pressure head. The floating base includes a base plate, a center seat, a floating plate, a roller assembly, and a support spring. The base plate is fixedly connected to the base of the hydraulic lifting device. A guide shaft is provided on the base plate, and the floating plate is slidably connected to the guide shaft. The roller assembly is provided on the upper surface of the floating plate. The support spring is provided between the lower surface of the floating plate and the base plate. The center seat is fixedly mounted on the base plate, and an inlet / outlet water pipe is provided at the center of the lower part of the center seat. A sealing gasket is provided on the upper end face of the center seat.

[0009] Before the water test, when the dual-control well-electric product moves from the first conveyor line to the roller assembly, the upper pressure head is higher than the water outlet at the upper end of the dual-control well-electric product, and the water inlet at the lower end of the dual-control well-electric product is higher than the sealing gasket. During the water test, the movable plate descends, and the dual-control well-electric product is pressed down by the upper pressure head. The upper end of the dual-control well-electric product abuts and seals with the upper pressure head, and the lower end of the dual-control well-electric product abuts and seals with the sealing gasket. A water pump and a water tank are installed below the floating base. The water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the side of the inlet and outlet water pipes through a first pipe. A one-way valve is installed on the first pipe, and a drain valve is installed at the bottom of the inlet and outlet water pipes. The exhaust channel is connected to the water tank through a second pipe, and an exhaust valve is installed on the second pipe.

[0010] Furthermore, the test machine also includes a controller and a touch screen. The drain valve and the vent valve are both solenoid valves. The touch screen, water pump, drain valve, and vent valve are electrically connected to the controller.

[0011] Furthermore, the exhaust valve is located at one end of the second pipe near the exhaust passage.

[0012] Furthermore, the vent valve is located at one end of the second pipe near the water tank.

[0013] Furthermore, the base plate is provided with a plurality of support seats, each support seat having an upward-facing mounting cavity, and the support spring is installed in the mounting cavity.

[0014] Furthermore, the base has a relief cavity located below the bottom plate, and the support extends into the relief cavity.

[0015] Furthermore, the support spring is a nitrogen spring.

[0016] Furthermore, the roller assembly includes a support plate and several roller units rotatably connected to the support plate.

[0017] Furthermore, a communication device installation station and a communication testing station are provided on the side of the second conveyor line.

[0018] A method for dual-control water testing of a well and electricity system, wherein, using the aforementioned water testing production line, the method further includes the following steps:

[0019] ① Install a flow metering device on the first conveyor line;

[0020] ② The semi-finished product of the well-electric dual control product moves from the first conveyor line to the water tester. At this time, the water inlet at the lower end of the well-electric dual control product is higher than the sealing gasket, and the upper pressure head is higher than the water outlet at the upper end of the well-electric dual control product.

[0021] ③ The hydraulic lifting device drives the movable plate to descend, and the upper end of the well electric dual control product abuts and seals with the upper pressure head; the floating plate moves down under pressure, and the lower end of the well electric dual control product abuts and seals with the sealing gasket;

[0022] ④ The water pump is turned on to supply water into the inlet and outlet pipes. The water flows into the flow metering device. At this time, the air valve is opened and the air passage exhausts air until the water is drained.

[0023] ⑤ After the set time, close the vent valve, and the water pump will continue to pressurize until the set pressure is reached;

[0024] ⑥ Turn off the water pump and maintain pressure for 15 minutes; if there is no pressure leakage, the product is qualified for pressure resistance.

[0025] ⑦ Open the drain valve to drain the water from the internal pipes of the dual-control well-electric product;

[0026] ⑧ When the movable plate rises, the supporting springs lift the floating plate.

[0027] ⑨ The semi-finished product of the well-electric dual control system is moved to the second conveyor line.

[0028] With the above structure, the well-electric dual-control water testing production line and water testing method of the present invention have at least the following beneficial effects:

[0029] I. By producing the dual-control well-electric system product on a continuous production line consisting of a first conveyor line, a testing machine, and a second conveyor line, frequent transportation is avoided, thus improving production efficiency. Due to the floating plate, the dual-control well-electric system product does not interfere with the upper end of the center seat when moving from the first conveyor line to the floating plate. During the testing of the dual-control well-electric system, the floating plate descends until the lower end of the product abuts against the sealing gasket for a seal. After the hydraulic lifting device rises, the floating plate can lift the product, thereby detaching it from the center seat, allowing for easy movement from the testing machine to the second conveyor line.

[0030] Second, by installing an air vent valve, when the water pump supplies water to the well-electric dual-control product from bottom to top, the internal air can be discharged through the upper air vent and the second pipe until the water flows out through the second pipe, at which point the air vent valve is closed. At this time, the well-electric dual-control product is full of water, and the water pump continues to pressurize until the set pressure is reached and then maintained. This avoids residual air inside from affecting the measurement stability.

[0031] Third, the vent valve is located at one end of the second pipe near the vent passage. This reduces the length of the pressure-bearing section in the second pipe during pressure holding, thus reducing the risk of leakage. Alternatively, the vent valve can be located at one end of the second pipe near the water tank, making its control more convenient.

[0032] Compared with the prior art, the present invention sets up the well-electric dual control product for transportation on the first and second conveyor lines, and sets up a test water machine in the middle to complete the test water of the flow metering module. This avoids the frequent transportation of the well-electric dual control product semi-finished product between workshops, and can efficiently complete the production of the well-electric dual control product.

Detailed Implementation

[0042] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0043] like Figures 1 to 7As shown, this invention relates to a well-electric dual-control water testing production line, which includes a water testing machine 2; it also includes a first conveyor line 1 and a second conveyor line 3 located before and after the water testing machine 2; the well-electric dual-control product 100 is conveyed on the first conveyor line 1 and the second conveyor line 3; a first installation station is provided on the side of the first conveyor line 1 for installing a flow metering device (not shown in the figure) inside the well-electric dual-control product 100, the flow metering device is installed between the upper connector 110 and the lower connector 120 of the well-electric dual-control product 100, and is located inside the well-electric dual-control product 100;

[0044] The test machine 2 includes a hydraulic lifting device 21, an upper pressure head 22, and a floating base 23; the hydraulic lifting device 21 includes a base 211, a guide column 212, a movable plate 213, and a hydraulic cylinder 214; the guide column 212 is mounted on the base 211, and the upper end of the movable plate 213 is connected to the hydraulic cylinder 214 and can move along the guide column 212 under the drive of the hydraulic cylinder 214; the upper pressure head 22 is mounted on the lower surface of the movable plate 213, and an exhaust channel 221 is formed inside the upper pressure head 22; The floating base 23 includes a base plate 241, a center seat 25, a floating plate 26, a roller assembly 27, and a support spring 28. The base plate 241 is fixedly connected to the base 211 of the hydraulic lifting device 21. A guide shaft 242 is provided on the base plate 241, and the floating plate 26 is slidably connected to the guide shaft 242. The roller assembly 27 is provided on the upper surface of the floating plate 26. The support spring 28 is provided between the lower surface of the floating plate 26 and the base plate 241. Preferably, the support spring 28 is a nitrogen spring. The center seat 25 is fixedly provided on the base plate 241. A water inlet / outlet pipe 251 is provided at the lower center of the center seat 25, and a sealing gasket 253 is provided on the upper end surface of the center seat 25.

[0045] Before the water test, when the well-electric dual-control product 100 moves from the first conveyor line 1 to the roller assembly 27, the upper pressure head 22 is higher than the water outlet at the upper end of the well-electric dual-control product 100, and the water inlet at the lower end of the well-electric dual-control product 100 is higher than the sealing gasket 253. During the water test, the movable plate 213 descends, and the well-electric dual-control product 100 is pressed down by the upper pressure head 22. The upper end of the well-electric dual-control product 100 abuts and seals against the upper pressure head 22, and the lower end of the well-electric dual-control product 100 abuts against the sealing gasket 253. Sealed; a water pump 291 and a water tank 292 are arranged below the floating base 23. The water inlet of the water pump 291 is connected to the water tank 292. The water outlet of the water pump 291 is connected to the side of the inlet and outlet pipe 251 through a first pipe 293. A one-way valve 294 is arranged on the first pipe 293. A drain valve 252 is arranged at the bottom of the inlet and outlet pipe 251. The exhaust channel 221 is connected to the water tank 292 through a second pipe 222. An exhaust valve 223 is arranged on the second pipe 222.

[0046] Thus, the present invention relates to a well-electric dual-control water testing production line and testing method, which produces the well-electric dual-control product 100 on a continuous production line consisting of a first conveyor line 1, a water testing machine 2, and a second conveyor line 3, avoiding frequent transportation and improving production efficiency. Due to the presence of a floating plate 26, when the well-electric dual-control product 100 moves from the first conveyor line 1 to the floating plate 26, the well-electric dual-control product 100 will not interfere with the upper end of the center seat 25. During the well-electric dual-control water testing, the floating plate 26 descends until the lower end of the well-electric dual-control product 100 abuts and seals against the sealing gasket 253. After the hydraulic lifting device 21 rises, the floating plate 26 can lift the well-electric dual-control product 100, thereby detaching it from the center seat 25, allowing it to be easily moved from the water testing machine 2 to the second conveyor line 3.

[0047] Preferably, the water testing machine 2 further includes a controller (not shown in the figure) and a touch screen (not shown in the figure). The drain valve 252 and the vent valve 223 are both solenoid valves. The touch screen, water pump 291, drain valve 252, and vent valve 223 are electrically connected to the controller. This allows for fully automated operation of the water testing process via the controller, improving test consistency and ensuring test accuracy. The controller can be a PLC controller. The touch screen allows for adjustment of test parameters for well-electric dual-control equipment of different specifications.

[0048] By setting an vent valve 223, when the water pump 291 supplies water to the well-electric dual-control product 100 from bottom to top, the internal air can be discharged through the upper vent channel 221 and the second pipe 222 until the water flows out from the second pipe 222, at which point the vent valve 223 is closed. At this time, the well-electric dual-control product 100 is filled with water, and the water pump 291 continues to pressurize until the set pressure is reached and then maintained. This avoids residual air inside affecting the measurement stability.

[0049] The second pipe 222 is a transparent flexible tube, allowing the user to easily observe whether there is water flow inside. The second pipe 222 can bend as the movable plate 213 rises and falls. Preferably, the vent valve 223 is located at one end of the second pipe 222 near the vent channel 221. This reduces the length of the pressure-bearing section in the second pipe 222 during pressure holding, reducing the risk of leakage. Alternatively, the vent valve 223 can be located at one end of the second pipe 222 near the water tank 292. This makes controlling the vent valve 223 more convenient. Especially when the vent valve 223 is a solenoid valve, the solenoid valve does not need to move up and down with the movable plate, simplifying the control wiring setup.

[0050] Preferably, the base plate 241 is provided with a plurality of support seats 243, each support seat 243 having an upward-opening mounting cavity 244, and the support spring 28 is installed in the mounting cavity 244. The support seats 243 are locked to the base plate 241, reducing the difficulty of forming the mounting cavity 244 on the base plate 241. Furthermore, the base 211 has a clearance cavity 245 located below the base plate 241, and the support seats 243 extend into the clearance cavity 245.

[0051] Preferably, the roller assembly 27 includes a support plate 271 and a plurality of roller units 272 rotatably connected to the support plate 271. Two sets of roller assemblies 27 are symmetrically arranged and distributed on both sides of the central seat 25. This provides more stable support for the well-electric dual-control product 100.

[0052] A limiting nut 261 is provided at the upper end of the guide shaft 242, and the highest position of the floating plate 26 is limited by the limiting nut 261. When the well-electric dual-control product 100 moves onto the roller assembly 27 on the floating plate 26, under the supporting force of the supporting spring 28, the floating plate 26 is at its highest position. At this time, the upper end of the roller assembly 27 on the floating plate 26 is flush with the first conveyor line 1 and the second conveyor line 3. Furthermore, a sliding sleeve 262 is provided on the floating plate 26, and the sliding sleeve 262 is slidably connected to the guide shaft 242.

[0053] Preferably, a communication device installation station and a communication testing station are provided on the side of the second conveyor line 3. Communication equipment is installed at the communication device installation station, and communication testing and debugging are subsequently performed.

[0054] The present invention also provides a method for dual-control well and electric water testing, which, using the above-mentioned water testing production line, further includes the following steps:

[0055] ① Install a flow metering device on the first conveyor line 1;

[0056] ② The semi-finished product 100 of the well-electric dual control product moves from the first conveyor line 1 to the test water machine 2. At this time, the water inlet at the lower end of the well-electric dual control product 100 is higher than the sealing gasket 253, and the upper pressure head 22 is higher than the water outlet at the upper end of the well-electric dual control product 100.

[0057] ③ The hydraulic lifting device 21 drives the movable plate 213 to descend, and the upper end of the well electric dual control product 100 abuts and seals with the upper pressure head 22; the floating plate 26 moves down under pressure, and the lower end of the well electric dual control product 100 abuts and seals with the sealing gasket 253.

[0058] ④ The water pump 291 is turned on to supply water into the inlet and outlet water pipes 251. The water flows into the flow metering device. At this time, the air valve 223 is opened and the air passage 221 exhausts air until the water is drained.

[0059] ⑤ After the set time, close the exhaust valve 223, and the water pump 291 continues to pressurize until the set pressure is reached;

[0060] ⑥ Turn off water pump 291 and maintain pressure for 15 minutes; if there is no pressure leakage, the product is qualified for pressure resistance.

[0061] ⑦ Open drain valve 252 to drain the water from the internal pipes of the well-electric dual-control product 100;

[0062] ⑧ When the movable plate 213 rises, the supporting spring 28 lifts the floating plate 26.

[0063] ⑨ The 100 semi-finished products of the well-electric dual-control product are moved to the second conveyor line 3.

[0064] Compared with the prior art, the present invention sets the well-electric dual control product 100 to be transported on the first conveyor line 1 and the second conveyor line, and sets a test water machine 2 in the middle to complete the test water of the flow metering module. This avoids the frequent transportation of the well-electric dual control product 100 semi-finished product between workshops and can efficiently complete the production of the well-electric dual control product 100.
