[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Reference Figures 1 to 8 A water pressure simulation test device comprises at least two vertically arranged water pipes 1, the upper end of the water pipe 1 is open and the lower end is closed, and the upper end side wall of each water pipe 1 is connected to a water supply pipe 2, and the lower end side wall is connected to a water receiving pipe 3, one end of the water receiving pipe 3 is connected to the water pipe 1, and the other end is connected to a test box 4 for sealing the module to be tested, and the water outlet of the test box 4 is also connected to a water outlet pipe 5, the distance between the openings of the water supply pipe 2 and the water receiving pipe 3 connected to the water pipe 1 meets the water pressure height to be tested, and the water flow direction inside the test box 4 and the opening direction of the water receiving pipe 3 connected to the water pipe 1 are located in the same horizontal plane, and the module to be tested is located on the water flow path inside the test box 4.

[0036] By setting up multiple vertically arranged water pipes 1, and connecting the upper end side wall of each water pipe 1 to the water supply pipe 2, and connecting the lower end side wall to the test box 4 for sealing the module to be tested, multiple modules to be tested can be tested at the same time. Before the test, by adjusting the height of the water supply pipe 2 of different water pipes 1, pressure testing of different modules to be tested can be achieved, thereby improving the problem that the current testing device cannot perform different pressure tests on different modules to be tested at the same time and the testing efficiency is low.

[0037] During testing, the module to be tested is first placed in the test box 4, sealed and locked. Water is then added to the water pipe 1 through the water supply pipe 2. The water in the water pipe 1 flows into the test box 4 through the water receiving pipe 3. After the water flow completely fills the test box 4, the module to be tested is under the test water pressure condition. The module to be tested is then powered on to test its functional operation under the test water pressure condition. The module water pressure simulation test device provided in this embodiment has a simple structure and convenient water pressure testing operation. It solves the difficulty of module testing in water, improves testing efficiency, reduces manufacturing costs and labor costs, and increases profits.

[0038] Based on the above embodiment, a shut-off valve 31 is provided on the water inlet pipe 3 to control the rhythm of water discharge into the test box 4. A water outlet valve 51 is also provided on the water outlet pipe 5. Closing the water outlet valve 51 completely fills the test box 4 with water, and opening the water outlet valve 51 completely drains the water from the test box 4.

[0039] The test box 4 is open at the top, and a sealing cover 41 is fitted and sealed at the top opening. The module to be tested can be placed into the test box 4 by opening the sealing cover 41. Sealing cover 41 is sealed by a sealing groove and sealing cotton. A through hole is formed through the sealing cover 41 for the wire to pass through. The wire is sealed to the through hole by sealing cotton or the like.

[0040] To ensure a sealed environment within test box 4, a sealing layer is incorporated into the interior of test box 4 to prevent leakage under water pressure. This ensures that the water pressure within test box 4 is consistent with the water pressure at the lower outlet of water pipe 1, thus ensuring test accuracy. Furthermore, a buffer layer is provided between the water inlet of test box 4 and the module carrier plate (for placing the module to be tested) to prevent water entering through the water inlet of test box 4 from directly impacting the module to be tested and causing damage to it.

[0041] The above-mentioned water pressure simulation test device also includes a support assembly 8, which is used to support each water pipe 1 in a vertical position to ensure the stability of the module water pressure simulation test device during the test, thereby improving the test accuracy; specifically, the support assembly includes a base 81, an intermediate support tube 82 arranged vertically and fixedly connected to the base 81 at the lower end, and a plurality of ear plates 83 fixedly connected to the base 81 and the intermediate support tube 82 at the same time, and each ear plate 83 is fixedly connected to each water pipe 1 one by one.

[0042] Reference Figures 2 to 8 , the upper end side wall of each water pipe 1 is provided with an installation groove 11, and the two groove arms of the installation groove 11 are provided with a slide groove 12, and the bottom of the installation groove 11 is fixed with a water retaining inner plate 13 connected to the inner wall of the water pipe 1, the water retaining inner plate 13 and the water pipe 1 have the same central axis, and the installation groove 11 is vertically slidably connected with a slide plate 14 with the same central axis as the water pipe 1, and the two ends of the slide plate 14 are adapted and slidably connected to the two slide grooves 12 respectively, and the inner wall of the slide plate 14 and the outer wall of the water retaining inner plate 13 have a distance and are filled with a sealing structure, which is fixed to the inner wall of the slide plate 14 and simultaneously abuts against the outer side of the water retaining inner plate 13 and the groove arms of the two slide grooves 12; one end of the water supply pipe 2 is connected to the slide plate 14.

[0043] When in use, the length of the slide plate 14 can be adjusted by canceling the seal of the sealing structure and then sliding the slide plate 14 vertically to achieve rapid adjustment of the height of the water supply pipe 2. Afterwards, a seal can be quickly formed between the sliding slide plate 14 and the water retaining inner plate 13 and the water pipe 1 through the sealing structure to prevent water leakage.

[0044] The water retaining inner plate 13 and the sliding plate 14 are both arc plates.

[0045] The sealing structure includes an inflation tube 15 and an expansion sleeve 16 whose side wall is connected to one end of the inflation tube 15 . The expansion sleeve 16 is fixedly connected to the inner side of the slide 14 and is arranged along the lower end and two horizontal ends of the slide 14 .

[0046] When sealing, connect the inflation tube 15 to the air source to inflate the expansion sleeve 16 and expand the expansion sleeve 16 until the expansion sleeve 16 is squeezed by the groove arm of the chute 12 and the water retaining inner plate 13 to form a seal, so as to prevent water leakage after water is filled into the water pipe 1 through the water supply pipe 2.

[0047] The expansion sleeve 16 can be made of rubber.

[0048] The sealing structure further includes an inflation valve 151 provided on the inflation tube 15 , so that the opening and closing of the airway can be controlled by the inflation valve 151 .

[0049] The groove arms of the two slide grooves 12 are each provided with a first sealing groove 121 that matches the expansion sleeve 16 . When the expansion sleeve 16 expands and deforms, it can enter and fill the first sealing groove 121 to improve the sealing effect.

[0050] The outer wall of the water retaining inner plate 13 is further provided with a plurality of transverse grooves 131 connecting the two first sealing grooves 121. The transverse grooves 131 are arranged vertically at intervals. When the expansion sleeve 16 expands and deforms, it can simultaneously enter and fill the first sealing grooves 121 and the transverse grooves 131 at the corresponding height, thereby improving the sealing effect.

[0051] The groove arms of the two chutes 12 are both provided with second sealing grooves 122 , and both ends of the water retaining inner plate 13 are adapted and slidably connected to the two second sealing grooves 122 to extend the path length of water seepage and further improve the sealing effect.

[0052] A water retaining outer plate 17 connected to the outer wall of the water pipe 1 is fixed to the bottom of the installation groove 11. The height of the water retaining outer plate 17 is lower than that of the water retaining inner plate 13, and a water storage tank 171 is formed between the water retaining outer plate 17 and the water retaining inner plate 13.

[0053] When the expansion sleeve 16 is exhausted, part of the water that enters the installation groove 11 can be discharged into the water storage tank 171 for storage, so as to prevent the water from directly flowing out of the water pipe 1 and affecting the test environment.

[0054] The water retaining outer plate 17 is connected to a drain pipe 172 that is connected to the bottom of the water storage tank 171 to drain the water in the water storage tank 171 in time through the drain pipe 172. A control switch (not shown) is provided on the drain pipe 172 to control the unified drainage.

[0055] Reference Figure 2 and Figure 3A fixing plate 6 is fixed to the top of each water pipe 1, and each fixing plate 6 is located directly above the corresponding mounting groove 11, and the fixing plate 6 is threadedly connected to a vertically arranged screw rod 7, and the lower end of the screw rod 7 is rotatably connected to the slide plate 14.

[0056] The slide plate 14 can be raised and lowered by rotating the screw rod 7 to complete the height adjustment of the slide plate 14 .

[0057] A handle 71 is provided at the upper end of the screw rod 7 so that the screw rod 7 can be rotated by the handle 71 .
