DETAILED DESCRIPTION

[0037] The following will be combined with the Figures 1-5 Further detailed description of the present application.

[0038] The embodiment of the present application discloses a water pump controller sealing detection equipment. Referring to Figure 1 A water pump controller sealing detection equipment includes a workbench 1, a control switch 2 and a plurality of detection devices 3. The plurality of detection devices 3 are evenly distributed above the workbench 1 at equal intervals, and the detection device 3 is fixedly connected with the workbench 1. The position and number of the control switch 2 correspond one by one to the position and number of the detection device 3, and the detection is mounted and connected on the corresponding detection device 3, the control switch 2 is used for inserting the interface of the water pump controller to make the water pump controller work, the upper end surface of the workbench 1 is provided with a water receiving groove 11, the water receiving groove 11 is used for receiving the water in the water pump controller after detection is completed, and the projections of the plurality of detection devices 3 in the vertical direction are all located in the water receiving groove 11. In the embodiment, the number of the detection device 3 is 2.

[0039] Referring to Figure 2The detection device 3 comprises a fixing column 31, a sealing seat 32 and a sealing column 33. The fixing column 31 comprises a column body 311 and a fixing plate 312. The column body 311 is fixed on the workbench 1 and vertically arranged. The fixing plate 312 is located at one end of the column body 311 away from the workbench 1 and extends out of the column body 311 in the horizontal direction. The fixing plate 312 is fixedly connected with the column body 311, and the cross section of the fixing column 31 in the vertical direction is in the shape of "L". The sealing column 33 is slidably arranged on the fixing plate 312 and can slide towards or away from the workbench 1. The sealing column 33 is used for inserting into the water outlet of the water pump controller to seal the water outlet of the water pump controller. A driving member one 4 is fixed above the fixing plate 312. The piston rod of the driving member one 4 is fixedly connected with the sealing column 33, and the driving member one 4 drives the sealing column 33 to move up and down. The sealing seat 32 is fixed on the workbench 1 and located directly below the sealing column 33. The sealing seat 32 is used for inserting into the water inlet of the water pump controller. The sealing seat 32 is fixed with a water inlet pipe 321, which is in communication with the inner cavity of the water pump controller. In the embodiment, the driving member one 4 is a pneumatic cylinder.

[0040] With reference to Figure 1 and Figure 2 A water storage tank 12 is fixed on the workbench 1 and located below the water collecting groove 11. The water storage tank 12 is in communication with the water inlet pipe 321. A driving member two 5 is fixed on the water storage tank 12 and in communication with the water storage tank 12 and the water inlet pipe 321. The driving member two 5 is used for driving the water in the water storage tank 12 to flow into the inner cavity of the water pump controller along the water inlet pipe 321. A pressure gauge 13 is fixed on the workbench 1 and used for detecting the water pressure in the inner cavity of the water pump controller. In the embodiment, the driving member two 5 is a water pump.

[0041] With reference to Figure 1 and Figure 2 A water outlet 14 is formed on the workbench 1 and in communication with the water collecting groove 11 and the water storage tank 12. The water in the water collecting groove 11 flows back into the water storage tank 12 through the water outlet 14, thereby improving the recycling rate of water.

[0042] In the actual detection process, the sealing seat 32 is inserted into the water inlet of the water pump controller. The driving member one 4 drives the sealing column 33 of the water pump to insert into the water outlet of the water pump controller to seal the water pump controller. The control switch 2 is inserted into the water pump controller to make the water pump controller open the flow channel. The driving member two 5 works to make the water pump into the inner cavity of the water pump controller. The value of the pressure gauge 13 is observed. When the value in the pressure gauge 13 reaches a predetermined value, the water inlet is stopped, and the value change of the pressure gauge 13 is observed. If the value is stable, the sealing property of the water pump controller is qualified. If the value is not stable, the sealing property of the water pump controller is unqualified.

[0043] With reference to Figure 3 and Figure 4The control switch 2 is slidably connected to the column body 311, and the sliding direction of the control switch 2 is horizontally arranged and parallel to the distribution direction between the column body 311 and the sealing column 33. When the sealing seat 32 is inserted into the water inlet of the water pump controller, the interface of the water pump controller is located on the moving path of the control switch 2.

[0044] With reference to Figure 3 and Figure 4 The workbench 1 is fixed with an elastic air bag 6, which is close to the sealing seat 32. When the sealing seat 32 is inserted into the water inlet of the water pump controller, the water pump controller extrudes the elastic air bag 6. The workbench 1 is fixed with an air pipe 61, and the column body 311 is provided with an air cavity 62, which is located on the side of the control switch 2 away from the sealing column 33. The air pipe 61 is connected to the elastic air bag 6 and the air cavity 62. The column body 311 is slidably connected with a piston block 63, and the end of the piston block 63 away from the control switch 2 extends into the air cavity 62. The piston block 63 slides in or out of the air cavity 62, and the end of the piston block 63 close to the control switch 2 abuts against the control switch 2. The sliding direction of the piston block 63 is parallel to the sliding direction of the control switch 2.

[0045] With reference to Figure 4 The column body 311 is provided with a mounting groove 64, which is located below the piston block 63. The column body 311 is fixed with an elastic member 65, which is located in the mounting groove 64. The elastic member 65 is below the piston block 63, and the upper end of the elastic member 65 is fixed with an abutting member 651, which slides up and down on the column body 311. The abutting member 651 slides in or out of the moving path of the piston block 63. The elastic member 65 abuts against the abutting member 651, so that the abutting member 651 has a tendency to move into the sliding path of the piston block 63. The end of the piston block 63 close to the abutting member 651 is provided with a positioning groove 631, which is used for clamping the abutting member 651. The end of the abutting member 651 close to the piston block 63 is formed with a guide surface 6511, which is a circular arc surface and protrudes towards the piston block 63. In this embodiment, the abutting member 651 is a small ball, and the elastic member 65 is a spring 36.

[0046] In the actual detection process, when the sealing seat 32 is inserted into the water inlet of the water pump controller, the water pump controller extrudes the elastic air bag 6, so that the gas in the elastic air bag 6 enters the air cavity 62 through the air pipe 61. As the gas in the air cavity 62 increases, the piston block 63 has a tendency to move close to the control switch 2. When the pressure of the gas acting on the piston block 63 is greater than the resistance of the abutting piece 651, the inner wall of the positioning groove 631 abuts against the guide surface 6511 to make the abutting piece 651 compress the elastic piece 65 to extend into the mounting groove 64, the abutting piece 651 is separated from the positioning groove 631, and the moving speed of the piston block 63 increases to drive the control switch 2 to be inserted into the interface of the water pump controller. Without the need for separate insertion of the control switch 2 after installation, the installation efficiency is improved.

[0047] With reference to Figure 2 and Figure 4 , the control switch 2 is fixed with a moving handle 21, which is used for moving the control switch 2 out of the water pump controller by the worker.

[0048] With reference to Figure 4 , the one end of the column body 311 close to the sealing column 33 is fixed with a protection ring 34, which is arranged around the outer periphery of the control switch 2. When not detected, the control switch 2 extends into the column body 311, the abutting piece 651 is clamped into the positioning groove 631, and the one end of the protection ring 34 away from the column body 311 is flush with the one end of the control switch 2 away from the column body 311.

[0049] With reference to Figure 4 , the protection ring 34 is hinged with a waterproof cover 35, which is located above the protection ring 34. The waterproof cover 35 is located on the side of the protection ring 34 away from the fixed ring. The hinge axis of the waterproof cover 35 is horizontally arranged and perpendicular to the sliding direction of the control switch 2. The waterproof cover 35 is used to cover the interface of the control switch 2.

[0050] With reference to Figure 4 and Figure 5 , the protection ring 34 is provided with an avoiding groove one 341, and the waterproof cover 35 is provided with an avoiding groove two 351. The avoiding groove one 341 and the avoiding groove two 351 are communicated. The protection ring 34 is fixed with a spring 36, which is located in the avoiding groove one 341. The one end of the spring 36 away from the avoiding groove one 341 extends into the avoiding groove two 351 and is fixedly connected with the waterproof cover 35. The waterproof cover 35 is hingedly connected to the protection ring 34 through a plurality of hinge rods, which are located on the opposite sides of the avoiding groove two 351 parallel to the rotation axis of the waterproof cover 35.

[0051] With reference to Figure 4 and Figure 5The water-swelling component 37 is fixed on the protection ring 34, and the water-swelling component 37 comprises a quicklime ring 371 fixed on the protection ring 34 and a thermal expansion and cold shrink block 372 fixed on the protection ring 34. The end of the protection ring 34 away from the column body 311 is provided with a fixing groove 342, and the fixing groove 342 is arranged around the outer periphery of the control switch 2. The fixing groove 342 is used for clamping the fixing ring to position and facilitate replacement of the quicklime ring 371. The thermal expansion and cold shrink block 372 is located on the side of the fixing groove 342 away from the control switch 2. The upper end surface of the protection ring 34 is provided with a clamping groove 343, and the thermal expansion and cold shrink block 372 is located in the clamping groove 343. In the embodiment, the material of the thermal expansion and cold shrink block 372 is copper.

[0052] When water splashes near the controller, the quicklime absorbs water and generates heat to make the thermal expansion and cold shrink block 372 expand and extend out of the clamping groove 343. The thermal expansion and cold shrink block 372 abuts against the waterproof cover 35 to make the waterproof cover 35 rotate. When the pulling force of the spring 36 on the waterproof cover 35 is located on the side of the waterproof cover 35 away from the column body 311 along the hinging axis, the spring 36 pulls the waterproof cover 35 to make the waterproof cover 35 quickly cover the interface of the control switch 2, so as to reduce the moisture entering. At this time, the distribution directions of the avoidance grooves one 341 and two 351 are horizontal.

[0053] When the waterproof cover 35 does not cover the interface of the control switch 2, the distribution directions of the avoidance grooves one 341 and two 351 are vertically arranged. The spring 36 pulls the waterproof cover 35 to make the waterproof cover 35 abut against the protection ring 34 and cover the clamping groove 343.

[0054] Referring to Figure 5 The end surface of the waterproof cover 35 is fixed with a water-absorbing pad 352. When the waterproof cover 35 covers the control switch 2, the water-absorbing pad 352 is located at the end of the waterproof cover 35 close to the control switch 2 and extends into the interface of the control switch 2.

[0055] The implementation principle of the water pump controller sealing detection equipment in the embodiment is as follows. In actual detection, after detection is completed, the handle 21 is moved towards the column body 311, the handle drives the control switch 2 to move and disengage from the water pump controller, the driving member one 4 drives the sealing column 33 to ascend and disengage from the water outlet, the water pump controller is taken out from the sealing seat 32, the water outlet of the water pump controller is placed downward on the water receiving groove 11, the next water pump controller is placed on the sealing seat 32, the driving member one 4 drives the sealing column 33 to insert into the water outlet and at the same time makes the water pump controller move downward, the sealing seat 32 inserts into the water inlet, and the installation is completed by the cooperation among the elastic air bag 6, the air pipe 61 and the piston block 63 to push the control switch 2 to insert into the interface of the water pump controller. In the process of detecting the sealing performance, the water pump controller in the water receiving groove 11 is always draining, so that the drainage and detection of different water pump controllers are simultaneously performed, which is beneficial to improve the detection efficiency.

[0056] In addition, by the cooperation between the waterproof cover 35 and the water-swelling assembly 37, the short circuit of the control switch 2 caused by water splashing is reduced.

[0057] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
