As the rubber sealing cover plate is continuously pressed down, the rubber sealing cover plate pushes the distribution box to drive the settling mechanism to descend into the liquid storage tank. When the settling mechanism is pushed down, an upward force is applied to the distribution box, thereby making the sealing performance between the distribution box and the rubber sealing cover plate stronger. Then the air compressor connected to the air inlet pipe can be started to inject gas into the distribution box to generate pressure, usually between 1-2 bar, adjusted according to actual needs. Then the worker can observe whether there are bubbles on the surface of the distribution box and the connecting part through the observation window. The generation of bubbles usually means that there is a gas leakage phenomenon in this part. During the observation through the observation window, the glass plate installed on the arc wall in the liquid storage tank can be used to observe the sealing condition of the back of the distribution box, so that the gas leakage parts on the front, side and back of the distribution box can be found, which helps to accurately judge the sealing condition of the distribution box. When the equipment is detected, the gas in the distribution box can be discharged and the electric push rod can be started to push the connecting plate to drive the rubber sealing cover plate to rise, thereby the settling mechanism can be pushed up together by the elastic force to push the distribution box up. The distribution box will always adhere to the lower surface of the rubber sealing cover plate during the rising process, avoiding the soap water flowing into the distribution box during the lifting process from the liquid storage tank, reducing the complexity of subsequent cleaning work, improving the convenience of the entire test operation, and the sealing performance test of the distribution box can be performed on various specifications and different shapes of distribution boxes.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 The embodiment provides the following technical scheme:

[0023] As Figures 1-3 shown, a power distribution box sealing test device, including: liquid storage tank 1, the upper surface of the liquid storage tank 1 is connected and installed with frame plate 107, the frame plate 107 is provided with guide rail groove 110 on both sides, the guide rail groove 110 is slidably installed with sedimentation mechanism 2, the upper surface of the sedimentation mechanism 2 can be placed for power distribution box, the both sides of the liquid storage tank 1 are fixedly installed with electric push rod 102, the piston rod between the two groups of electric push rod 102 is fixedly installed with connecting plate 103, the lower surface of the connecting plate 103 is fixedly installed with push column 108, the lower surface of the push column 108 is fixedly installed with rubber cover plate 105, so that the rubber cover plate 105 can be pushed by the electric push rod 102 and tightly covered on the upper surface of the power distribution box, and the power distribution box can be pushed to drive the sedimentation mechanism 2 to sink into the liquid storage tank 1, the upper surface of the frame plate 107 is fixedly installed with fence frame 106.

[0024] Among them, the liquid storage tank 1 stores soap water.

[0025] Among them, the other end of the liquid storage tank 1 is semicircular and the inner arc wall is installed with glass plate 109, so that the glass plate 109 can reflect the image of the power distribution box settled in the liquid storage tank 1 to the observation window 101, and the observation window 101 is fixedly installed at one end of the liquid storage tank 1.

[0026] Among them, the upper surface of the push column 108 is connected and installed with air inlet pipe 104, the air inlet pipe 104 is connected to the lower surface of the rubber cover plate 105, and the air inlet pipe 104 is connected with the air compressor, so that the air inlet pipe 104 can inject gas into the power distribution box.

[0027] When the sealing performance of the distribution box is tested, the distribution box can be placed on the upper surface of the settling mechanism 2, and then the electric push rod 102 can be started to pull down the connecting plate 103 at one end of the piston rod, so that the connecting plate 103 drives the rubber sealing cover plate 105 on the lower surface of the push column 108 to cover the slot of the distribution box. As the rubber sealing cover plate 105 is continuously pressed down, the rubber sealing cover plate 105 pushes the distribution box to drive the settling mechanism 2 to descend into the liquid storage tank 1. When the settling mechanism 2 is pushed down, an upward thrust is applied to the distribution box, so that the sealing performance between the distribution box and the rubber sealing cover plate 105 is stronger. Then, the air compressor connected with the air inlet pipe 104 can be started to inject gas into the distribution box to generate pressure, which is usually between 1-2 bar, adjusted according to actual needs. Then, the staff can observe whether bubbles are generated on the outer surface and the connecting part of the distribution box through the observation window 101. The generation of bubbles usually means that there is a gas leakage phenomenon at this part. During the observation through the observation window 101, the back sealing condition of the distribution box can be observed through the glass plate 109 installed on the arc wall in the liquid storage tank 1, so that the gas leakage parts on the front, side and back of the distribution box can be found, which helps to accurately judge the sealing condition of the distribution box. When the equipment is detected, the gas in the distribution box can be discharged, and the electric push rod 102 can be started to push the connecting plate 103 to drive the rubber sealing cover plate 105 to rise, so that the settling mechanism 2 is pushed up together through the elastic thrust, and the distribution box is always attached to the lower surface of the rubber sealing cover plate 105 during the rising process, avoiding the soap water flowing into the distribution box during the lifting process from the liquid storage tank 1, which reduces the complexity of subsequent cleaning work and improves the convenience of the whole test operation. During the sealing performance test of the distribution box, various specifications and different shapes of distribution boxes can be sealed and detected, as long as the size of the distribution box is not greater than the size of the settling mechanism 2 and the rubber sealing cover plate 105, which can cover more types of distribution boxes and reduce the situation that the distribution box cannot be detected due to the difference in specifications and shapes, thereby improving the comprehensiveness of the detection.

[0028] As shown in Figure 4 The settling mechanism 2 includes a slide column 205 fixedly installed in the guide groove 110. The outer surface of each group of slide columns 205 is slidably installed with a guide block 201 at both ends. The guide block 201 is rotatably installed with a roller 202 on the upper and lower surfaces, so that the guide block 201 rolls in the guide groove 110 through the roller 202. Each two groups of guide blocks 201 are fixedly installed with a connecting block 203, and the two groups of connecting blocks 203 are fixedly installed with a PVC transparent soft rubber plate 204.

[0029] The outer surface of the slide column 205 is sleeved with a spring 206 at both ends, and the two ends of the spring 206 are fixedly connected to the guide rail block 201 and one end of the baffle disc 207, respectively.

[0030] Through the design of the guide rail block 201, the roller 202, the connecting block 203, the PVC transparent soft rubber plate 204 and the spring 206, when the rubber sealing cover plate 105 is driven to press down on the upper surface of the distribution box, it will push the distribution box to press on the upper surface of the PVC transparent soft rubber plate 204 to sink downward, and the PVC transparent soft rubber plate 204 will pull the two guide rail blocks 201 at both ends to slide synchronously to the center in the guide rail groove 110, and the guide rail block 201 will slide on the outer surface of the slide column 205 and press on one end of the spring 206 in the process of sliding in the guide rail groove 110, and the spring 206 will exert a spring thrust on the guide rail block 201, thereby enabling the guide rail block 201 to pull the PVC transparent soft rubber plate 204 to exert a lifting force on the distribution box through the spring thrust, and this lifting force cooperates with the pressing action of the rubber sealing cover plate 105 to make the sealing between the distribution box and the rubber sealing cover plate 105 more tight, and then the air compressor connected to the air inlet pipe 104 can be started to inject gas into the distribution box, and the observation window 101 can be used to observe whether there is bubble generated on the outer surface of the distribution box and the connecting part, when the equipment is detected, the gas in the distribution box can be discharged, and the electric push rod 102 can be started to push the connecting plate 103 to drive the rubber sealing cover plate 105 to lift up, thereby enabling the PVC transparent soft rubber plate 204 to push the distribution box up by the lifting force exerted by the spring 206, so that the distribution box will always adhere to the lower surface of the rubber sealing cover plate 105 during the lifting process, avoiding the soap water flowing into the distribution box during the lifting process from the liquid storage tank 1, reducing the complexity of subsequent cleaning work, improving the convenience of the whole test operation, and the whole process from sealing to injecting gas detection to lifting after the test is completed, each component works in coordination, and the good sealing effect can reduce the possibility of repeated testing due to poor sealing, and avoid the waste of cleaning time caused by pollution, thereby improving the efficiency of the whole sealing test.

[0031] According to the above technical scheme, the working steps of the present scheme are summarized and combed: when testing the sealing performance of the distribution box, the distribution box can be placed on the upper surface of the PVC transparent soft rubber plate 204, and then the electric push rod 102 can be started to pull down the connecting plate 103 at one end of the piston rod, so that the connecting plate 103 can drive the rubber sealing cover plate 105 on the lower surface of the push column 108 to cover the mouth groove of the distribution box. With the continuous downward movement of the rubber sealing cover plate 105, the rubber sealing cover plate 105 can push the distribution box to sink downward on the upper surface of the PVC transparent soft rubber plate 204. During the downward movement of the PVC transparent soft rubber plate 204, the guide rail blocks 201 at both ends will be pulled to slide synchronously to the center in the guide rail groove 110. During the sliding of the guide rail blocks 201 in the guide rail groove 110, the guide rail blocks 201 will slide on the outer surface of the slide column 205 and press on one end of the spring 206. The spring 206 will exert a spring force on the guide rail blocks 201, so that the guide rail blocks 201 can pull the PVC transparent soft rubber plate 204 to exert a lifting force on the distribution box through the spring force. This lifting force cooperates with the downward movement of the rubber sealing cover plate 105 to make the sealing between the distribution box and the rubber sealing cover plate 105 more tight. Then, the air compressor installed in communication with the air inlet pipe 104 can be started to inject gas into the distribution box to generate pressure, usually between 1-2bar, adjusted according to actual needs. Then, the worker can observe whether there is bubble generation on the outer surface and connecting part of the distribution box through the observation window 101. The generation of bubbles usually means that there is air leakage in that part. During the observation through the observation window 101, the back sealing condition of the distribution box can be observed through the glass plate 109 installed on the inner arc wall of the liquid storage tank 1, so that the air leakage parts on the front, side and back of the distribution box can be found, which helps to accurately judge the sealing condition of the distribution box. When the equipment is detected, the gas in the distribution box can be discharged, and the electric push rod 102 can be started to push the connecting plate 103 to lift the rubber sealing cover plate 105, so that the PVC transparent soft rubber plate 204 can be pushed upward by the lifting force exerted by the spring 206, and the distribution box will always adhere to the lower surface of the rubber sealing cover plate 105 during the upward movement, avoiding the soap water flowing into the distribution box during the lifting from the liquid storage tank 1, causing cleaning difficulty. The whole process from sealing to gas injection detection to lifting after testing is completed, and each component works in coordination.

[0032] In summary: during the sealing performance test of the distribution box, various specifications and different shapes of distribution boxes can be sealed and detected. As long as the size of the distribution box is not greater than the size of the sinking mechanism 2 and the rubber sealing cover plate 105, more types of distribution boxes can be covered, and the situation that the distribution box cannot be detected due to the difference in specification and shape of the distribution box can be reduced, thereby improving the comprehensiveness of the detection.
