Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and in particular to an industrial high voltage assembly test bench with a cleaning function. Background Technology

[0002] Industrial high-pressure assemblies are core components in engineering machinery, hydraulic systems, and other fields. Their sealing performance, pressure bearing capacity, and other parameters directly affect the operational stability of the entire machine. Therefore, they must undergo precise testing on a professional testing platform before leaving the factory. However, high-pressure assembly testing equipment generally lacks integrated cleaning and environmental protection solutions. Firstly, in traditional testing processes, high-pressure assembly interfaces easily retain processing debris, oil stains, storage dust, and other impurities. Manual wiping and simple air blowing cleaning methods are inefficient, have uneven coverage, and poor consistency. These methods not only fail to thoroughly remove impurities from interface gaps but also easily lead to unstable cleaning results due to operational differences. This can cause joint seal failure and media leakage during testing, resulting in distortion of core test data such as pressure and sealing performance, directly affecting… Firstly, manual cleaning is problematic for product qualification assessment. Secondly, it is difficult to adapt to the high-efficiency testing needs of industrial mass production, becoming a key bottleneck restricting the automation of the testing process. Thirdly, most cleaning solutions are for single use, which not only wastes resources, but also pollutes the production environment due to the indiscriminate discharge of untreated waste liquid, failing to meet green industrial production standards. Furthermore, the testing area lacks targeted protective structures, resulting in a high risk of high-pressure media splashing and cleaning solution overflow during testing and cleaning, threatening the safety of operators and easily corroding internal components of the equipment, shortening its service life. In addition, traditional cleaning components have poor compatibility with the testing platform, requiring the disassembly of multiple parts for maintenance, which is cumbersome and costly, further limiting the promotion and application of the equipment in industrial scenarios.

[0023] Please see the appendix Figure 1 -Appendix Figure 5This utility model provides an embodiment of an industrial high-voltage assembly test bench with a cleaning function, comprising a frame 1, a slightly inclined platform 2 in the middle of the frame 1, a drain hole 3 on one side of the upper surface of the slightly inclined platform 2, a filter screen 4 inserted into the drain hole 3, a connecting pipe 5 connected to the bottom flange of the drain hole 3, a filter box 6 at the end of the connecting pipe 5, and the filter box 6 located on the outside of the frame 1; a test chamber 7 is provided above the slightly inclined platform 2, a lower baffle 8 and an upper baffle 9 are provided on the front side of the test chamber 7, and a sliding groove 10 is provided on the frame 1 corresponding to the position of the lower baffle 8, the lower baffle 8 can slide along the sliding groove 10, and cooperate with the upper baffle 9 to realize the front of the test chamber 7. The side-opening mechanism prevents media splashing and cleaning fluid overflow. A control box 13 is installed on the upper surface of one side of the slightly inclined platform 2. A bottom cavity 14 is opened below the slightly inclined platform 2, which is located within the frame 1. A storage tank 16 is installed inside the bottom cavity 14. A delivery pipe 17 is installed between the storage tank 16 and the filter box 6. The control box 13 controls the overall operation of the equipment. The bottom cavity 14 accommodates the storage tank 16, and the delivery pipe 17 enables the cleaning fluid to return after filtration. An outlet pipe 18 is sleeved at the output end of the storage tank 16. A spray pipe 19 is installed at the end of the outlet pipe 18. The outlet pipe 18 delivers the cleaning fluid, and the spray pipe 19 sprays cleaning fluid into the test chamber 7. A rear door 21 is installed on the rear side of the frame 1. A cylinder 22 is installed between the top of the door 21 and the top of the frame 1. The cylinder 22 drives the rear door 21 to open and close, facilitating the placement and removal of the test piece and sealing the test chamber 7. A mounting port 23 is provided on the inner left side of the frame 1. A flange connects a pressure air blowing pipe 24 to the mounting port 23. A connecting pipe 25 is sleeved on the left end of the pressure air blowing pipe 24. A left-inclined air blowing manifold 26 is installed on the connecting pipe 25. The mounting port 23 fixes the pressure air blowing pipe 24, and the connecting pipe 25 diverts the airflow to the left-inclined air blowing manifold 26. A right-inclined air blowing manifold 27 is provided on the right end of the pressure air blowing pipe 24. Both the left-inclined air blowing manifold 26 and the right-inclined air blowing manifold 27 are equipped with air jet ports 28. The air blowing manifold 27, in conjunction with the left-tilted air blowing manifold 26, achieves multi-angle air blowing cleaning through the air jet nozzle 28; an installation groove 11 is provided on one inner wall of the frame 1, corresponding to the outer wall of the lower baffle 8, and a guide rail 12 is provided in the installation groove 11. The installation groove 11 fixes the guide rail 12, and the guide rail 12 guides the lower baffle 8 to slide smoothly; the spray pipe 19 is set at the top of the frame 1, and a fixing block 20 is fixedly connected on the inner wall of the top of the frame 1 at the position corresponding to the spray pipe 19. The fixing block 20 securely fixes the spray pipe 19 to ensure accurate spraying position; bottom doors 15 are provided on both the front and rear sides of the bottom cavity 14, and the bottom doors 15 facilitate opening the bottom cavity 14 to inspect and maintain components such as the liquid storage tank 16.

[0024] Working Principle: Using this invention, first open the bottom doors 15 on both sides of the bottom cavity 14 to check if the cleaning fluid level in the storage tank 16 inside the bottom cavity 14 is sufficient. Simultaneously verify that the connection between the storage tank 16 and the filter box 6 is sealed and leak-free. Through the mounting port 23 on the inner surface of the left side of the frame 1, confirm the stable assembly of the pressure air blowing pipe 24 and the connecting pipe 25. Check that the jet nozzles 28 on the left-tilted air blowing manifold 26 and the right-tilted air blowing manifold 27 are unobstructed and that the airflow channels are unobstructed. Furthermore, verify that the spray pipe 19 fixed to the top of the frame 1 by the fixing block 20 and the outlet pipe 18 connected to it are unobstructed, ensuring that all components of the cleaning system are in normal working condition. Then, check the control box on the upper surface of one side of the slightly tilted table 2. 13. The pre-cleaning procedure is initiated. After the pressure air blowing tube 24 is connected to the high-pressure air source, the airflow is split through the connecting tube 25 to the left-tilted air blowing manifold 26 and the right-tilted air blowing manifold 27, and finally sprayed out from each jet nozzle 28 to blow air into the interior of the test chamber 7 and the surface of the micro-tilted platform 2 from multiple angles without dead angles, thoroughly removing residual dust and impurities. Immediately afterwards, the cleaning liquid in the storage tank 16 is transported to the spray pipe 19 through the outlet pipe 18, and sprayed evenly into the test chamber 7 from the spray pipe 19 to pre-clean the micro-tilted platform 2 and the inner wall of the test chamber 7. The cleaning waste liquid generated at this time naturally converges along the tilt angle of the micro-tilted platform 2, and after being initially filtered by the filter screen 4 clamped in the leakage hole 3 for large particulate impurities, it is introduced into the outside of the frame 1 through the connecting pipe 5 connected to the bottom flange of the leakage hole 3. The filter box 6 undergoes deep purification treatment. After pre-cleaning, the cylinder 22 is retracted by the control box 13, which drives the rear door 21 on the back of the frame 1 to open upward. At the same time, the guide rail 12 installed in the mounting groove 11 on one side of the frame 1 slides the lower door 8 downward along the sliding groove 10 and opens simultaneously. The upper door 9 is opened at the same time, exposing the test position inside the test chamber 7. The industrial high-voltage assembly to be tested is placed stably on the slightly inclined table 2 and adjusted to the preset position suitable for testing. Then, the lower door 8 is pushed upward along the sliding groove 10 by the control box 13 along the guide rail 12 to close, and the upper door 9 is closed. Then, the cylinder 22 is extended to drive the rear door 21 downward to close tightly, so that the test chamber 7 forms a closed environment and prevents the high-voltage medium from flying out during the test and subsequent cleaning. If splashing or overflowing cleaning fluid occurs, the high-pressure testing system is then activated via control box 13 to test the core parameters of the industrial high-pressure assembly under test, such as sealing performance and pressure tolerance, within test chamber 7. If a small amount of media leakage or residual liquid occurs during the test, it will naturally flow along the inclined surface of the slightly inclined platform 2 to the leakage hole 3, and after preliminary filtration by filter screen 4, it will enter the connecting pipe 5, preventing liquid accumulation from affecting test accuracy or equipment operation. After the test is completed, the post-cleaning program is activated via control box 13, repeating the air blowing and spraying actions of the pre-cleaning stage. High-pressure airflow is ejected from the air nozzles 28 of the left-tilted air blowing manifold 26 and the right-tilted air blowing manifold 27, combined with the cleaning fluid sprayed by spray pipe 19, to thoroughly clean the surface of the high-pressure assembly and the interfaces of any remaining test media and impurities after the test.To ensure the cleanliness of the assembly meets the requirements for subsequent assembly or storage, the waste liquid generated after cleaning follows the same process as the waste liquid generated during pre-cleaning. It is collected by the slightly inclined platform 2, passed through the leakage hole 3, preliminarily filtered by the filter screen 4, and then transported to the filter box 6 for purification via the connecting pipe 5. Finally, it flows back to the storage tank 16 in the bottom cavity 14 through the infusion pipe 17, achieving the recycling of the cleaning liquid. After cleaning, the cylinder 22 is controlled by the control box 13 to retract and open the rear gate 21. The lower gate 8 slides along the guide rail 12 to the bottom of the sliding groove 10 to open, opening the upper gate 9 and removing the test equipment. A qualified industrial high-pressure assembly, after completing a single test cycle, can periodically have its bottom door 15 of the bottom cavity 14 opened during long-term use to replenish or replace the cleaning fluid in the storage tank 16, check the sealing of the connections of the inlet pipe 17 and outlet pipe 18, and clean the filter screen 4 inside the leakage hole 3 to prevent impurities from clogging it. The pressure air blowing long pipe 24, connecting pipe 25, and left-tilted air blowing manifold 26 and right-tilted air blowing manifold 27 can be inspected through the installation port 23, and residual impurities in the jet nozzle 28 can be cleaned to ensure the long-term stable operation of all components of the equipment.
