Description

Technical Field

[0001] This utility model relates to the field of lighting testing technology, specifically a waterproof performance testing box for mining lighting fixtures. Background Technology

[0002] Mining lamps are a general term for special lighting fixtures used in mines. Waterproof testing of mining lighting fixtures is an important step to ensure that the fixtures can work normally and reliably in humid or harsh environments. Waterproof testing methods usually include water spray tests or immersion tests.

[0003] When testing the waterproof performance of existing mining lighting fixtures, it is difficult to evenly cover the surface of the fixture with sprayed water, which reduces the accuracy of the waterproof performance test. Furthermore, during immersion tests, the fixtures are prone to floating on the surface of the water due to buoyancy, resulting in the fixtures not being fully submerged in water. This increases the limitations of waterproof testing for mining lighting fixtures and reduces testing efficiency. Utility Model Content

The output end of the drive motor 18 is provided with a first gear, and the outside of the rotary tube 17 is provided with a second gear that meshes with the first gear. By using the meshing structure of the two sets of gears, it is easy to drive the rotary tube 17 to rotate.

[0024] A mounting groove 21 is provided on one side of the top of the placement groove 9. A second servo motor 20 is provided at one end of the mounting groove 21. The second servo motor 20 is a DH18 series. The output end of the second servo motor 20 is connected to a second threaded rod 23. An adapted internal threaded block 22 is provided on the outer side of the second threaded rod 23. A baffle 12 is provided on one side of the internal threaded block 22. A threaded hole is opened on one side inside the placement groove 9. The threaded hole is adapted to the first threaded rod 8. Limiting grooves are opened on both sides inside the housing 1. A limiting block is provided on the inner side of the limiting groove. The limiting block is connected to the placement groove 9 to increase the stability of the lifting and lowering adjustment of the placement groove 9. The baffle 12 slides horizontally on the top of the placement groove 9. A guide groove is provided on one side of the top of the placement groove 9. The baffle 12 slides horizontally on the inner side of the guide groove. The setting of the guide groove causes the baffle 12 to slide horizontally in the guide groove.

[0025] The top of the baffle 12 is provided with an electric push rod 14, and the output end of the electric push rod 14 is connected to a pressure plate 13. The electric push rod 14 is model DTZ-500.

[0026] A limiting groove is provided on one side of the mounting groove 21. The internal thread block 22 extends out of the limiting groove and is connected to a baffle 12. The baffle 12 is in a closed fit with the placement groove 9, which facilitates the horizontal adjustment of the baffle 12 and closes the top surface of the placement groove 9.

[0027] Example 1, as Figure 1-4 As shown, a transparent window is provided at one end of the box 1 and on the outside of the door 2. The water tank 6 and the placement tank 9 are both made of transparent material. Through the transparent window and the transparent structure of the water tank 6 and the placement tank 9, it is convenient for the operator to observe the waterproof test status of the lamps from the outside of the box 1, so as to visually see whether the lamps illuminate normally under the action of water spray and immersion, thereby judging whether the waterproof performance of the lamps meets the standards.

[0028] Example 2, as Figure 1-4 As shown, the guide pipe 15 has a U-shaped structure. Spray nozzles are provided at the bottom of both sides of the inner side of the guide pipe 15. The guide pipe 15 and the two spray nozzles extend to the inner side of the placement groove 9 and rotate. The U-shaped structure of the guide pipe 15 extends to the inner side of the placement groove 9 so that the spray nozzles are set at the tail end of the guide pipe 15. This causes the spray nozzles to spray evenly on the surface of the lamps placed on the lamp placement platform 11 in the placement groove 9 under the rotation of the guide pipe 15, thereby improving the uniformity of spraying and the accuracy of detection.

[0029] Working principle: This is the waterproof performance testing box for mining lighting fixtures;

[0030] When the device performs waterproof testing on mining lighting fixtures, first open the chamber door 2 and place the fixtures into the fixture placement platform 11 in the placement slot 9. Then, the first servo motor 3 is started to drive the first threaded rod 8 to rotate, causing the placement slot 9 to rise and adjust with the rotation of the first threaded rod 8, and the two sets of guide pipes 15 to extend into the placement slot 9. At this time, the water pump 7 is started to guide the water in the water tank 6 into the rotating pipe 17 from the circulation pipe 5. Then, the drive motor 18 is started to drive the gear set 19 to mesh, causing the gear set 19 to drive the rotating pipe 17 and the guide pipe 15 to rotate, so that the water extends through the rotating pipe 17 to the guide pipe 15 and is finally sprayed out from the two sets of nozzles. With the rotation of the guide pipe 15, the fixtures in the fixture placement platform 11 are sprayed efficiently and evenly, so that the operator can observe from outside the box 1 whether the fixtures can illuminate normally under the spray test.

[0031] After the lamps undergo spray testing, the second servo motor 20 can be activated to move the internal threaded block 22 horizontally, causing the internal threaded block 22 to move the baffle 12 to cover the top surface of the placement slot 9. At this time, the electric push rod 14 can be activated to move the pressure plate 13 to fit and position the lamps on the lamp placement platform 11. Then, the first servo motor 3 can be activated to rotate the first threaded rod 8, causing the placement slot 9 to descend. The placement slot 9 extends into the water tank 6 under the filtration of the filter screen 10, and the water fills the cavity of the placement slot 9. At this time, the baffle 12 and the pressure plate 13 can close and position the lamps, so that the lamps are fully immersed in the water, preventing the lamps from floating under the buoyancy of the water. Thus, the waterproof lighting test of the lamps is carried out by the immersion test. This test structure uses the combination of spray test and immersion test to improve the waterproof testing efficiency of the lamps.
