Description

Technical Field

[0001] This invention belongs to the field of control cabinet testing technology, and particularly relates to a waterproof testing device for electrical control cabinets. Background Technology

[0002] An electrical control cabinet is a device used for centralized control and protection of electrical equipment. It is widely used in industrial, commercial, and construction fields. Most electrical control cabinets are welded from sheet metal. If gaps appear after welding, it will affect the subsequent use of the control cabinet and the waterproof protection of the electrical components inside the control cabinet. Therefore, waterproof testing is required after the cabinet is manufactured.

[0003] Existing devices have a narrow detection range and cannot simultaneously perform probe detection, underwater detection, and underwater detection under increased water pressure. Existing devices are mostly conventional static detection devices and cannot simulate detection under different environments and conditions, such as detection during transportation. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A waterproof testing device for an electrical control cabinet includes a base; a water tank filled with water is fixed to the left side of the top surface of the base; a frame is fixed to the top surface of the base, the frame has a concave structure, a first hydraulic cylinder is fixed to the top surface of the inner wall of the frame, a base block is fixed to the extended end of the first hydraulic cylinder, the base block has a rectangular block structure, two spring rods are fixed to the bottom surface of the base block, and a rectangular block structure pressure block is fixed to the extended end of the two spring rods, the pressure block is located directly above the water tank.

[0006] Preferably, the water tank, frame, first hydraulic cylinder, base block, spring rod, and pressure block together constitute the first detection assembly.

[0007] Preferably, a second detection component is installed on the base. The second detection component consists of a second hydraulic cylinder, a cover plate, and an air inlet pipe. Four second hydraulic cylinders are fixed on the top surface of the base. The extended ends of the four second hydraulic cylinders are all fixed on the bottom surface of the cover plate. The cover plate is located directly above the water tank. When the four second hydraulic cylinders retract, the cover plate is fastened to the water tank.

[0008] Preferably, an air inlet pipe is welded to the top surface of the cover plate, and a valve is installed on the air inlet pipe.

[0009] Preferably, the cover plate has a stepped structure, with the outer wall of the lower half of the cover plate contacting the inner wall of the water storage tank, and the stepped part of the cover plate contacting the top surface of the water storage tank.

[0010] Preferably, the base is equipped with an auxiliary component, which consists of a sliding frame, a mounting frame, a detection probe, a mounting block, a first motor, a threaded rod, a guide rod, a placement plate, a limit seat, a protrusion, and a toggle rod. Two sliding frames are symmetrically welded to the top surface of the base, and a mounting frame slides on the two sliding frames. The mounting frame has a concave structure, and the detection probe is mounted in a linear array on the top surface of the inner wall of the mounting frame.

[0011] Preferably, a mounting block is fixed to the right side of the top surface of the base, and a first motor is fixed to the left end of the mounting block. A threaded rod is fixed to the output shaft of the first motor, and the threaded rod is threadedly connected to the mounting bracket.

[0012] Preferably, the top surface of the base is welded with four stepped shaft-shaped guide rods, and a placement plate slides on the four guide rods. The top surface of the placement plate is welded with a U-shaped limiting seat, which is located below the detection probe.

[0013] Preferably, the bottom surface of the placement plate is welded with protrusions in a linear array, and the protrusions are semi-cylindrical structures; an L-shaped actuating rod is welded to the rear end face of the inner wall of the mounting frame, and the upper end of the actuating rod contacts the bottom surface of the placement plate. When the actuating rod moves left and right with the mounting frame, the actuating rod is in continuous contact with the protrusions.

[0014] Preferably, a drive assembly is installed on the mounting block. The drive assembly consists of a second motor and a toggle block. A second motor is fixed to the right end face of the mounting block, and a toggle block is fixed to the output shaft of the second motor. The toggle block is located below the placement plate. When the second motor rotates, the toggle block makes elastic contact with the bottom end face of the placement plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] Multiple testing methods are combined to ensure comprehensive testing: the first testing component performs basic leak detection by immersing the control cabinet in water in the storage tank and observing air bubbles; the second testing component increases the pressure inside the storage tank by connecting an air supply pump through an air inlet pipe, conducting more in-depth leak detection. These two testing methods work together to test the control cabinet's leak resistance under different pressure environments, ensuring accurate and reliable test results.

[0017] The structural design is reasonable, ensuring safe and accurate testing: the spring rod in the first testing component acts as a buffer when the pressure block presses down on the control cabinet, preventing the first hydraulic cylinder from overextending and damaging the control cabinet, thus protecting the equipment being tested. The cover plate adopts a stepped structure, which fits tightly with the water tank, effectively improving the sealing performance, avoiding air leakage that could affect testing accuracy, and providing a reliable sealing environment for pressure testing.

[0018] Automated testing improves testing efficiency: The first motor drives the threaded rod, which in turn moves the mounting bracket and the testing probe back and forth, enabling automatic testing of the control cabinet without manual operation, saving manpower and improving testing efficiency. At the same time, it can achieve comprehensive testing of different parts of the control cabinet, avoiding omissions.

[0019] Simulating various usage scenarios expands the detection range: In the auxiliary components, the interaction between the toggle lever and the protrusion generates vibration when the mounting bracket moves, simulating the state of the control cabinet after transportation for detection; in the drive components, the continuous movement of the toggle block on the placement plate enables detection under vibration conditions of the control cabinet. These designs simulate different conditions that the control cabinet may encounter during actual use and transportation, making the detection more closely aligned with real-world application scenarios, enabling the discovery of potential problems, effectively expanding the detection range, and improving the practicality and effectiveness of the detection.

[0020] Limiting and fixing functions enhance testing stability: The limit seats on the placement plate can limit the control cabinet to prevent it from shifting and falling during the testing process, ensuring the safety and stability of the testing process, and also ensuring the accuracy and consistency of the test data.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The following electrical components are all electrically connected to the external PLC controller.

[0032] Reference Figure 1 - Figure 8 A waterproof testing device for an electrical control cabinet includes a base 1; a water tank 201 filled with water is fixed to the left side of the top surface of the base 1; a frame 202 is fixed to the top surface of the base 1, the frame 202 has a concave structure, a first hydraulic cylinder 203 is fixed to the top surface of the inner wall of the frame 202, a base block 204 is fixed to the extended end of the first hydraulic cylinder 203, the base block 204 has a rectangular block structure, two spring rods 205 are fixed to the bottom surface of the base block 204, and a rectangular block structure is fixed to the extended end of the two spring rods 205. The pressure block 206 is located directly above the water tank 201. When testing the control cabinet, the control cabinet is placed inside the water tank 201, and the first hydraulic cylinder 203 is driven to extend. The first hydraulic cylinder 203 drives the pressure block 206 to move downward. The pressure block 206 squeezes the control cabinet and presses it into the water in the water tank 201. At this time, observe whether any bubbles emerge. When the control cabinet is pressed downward, the buffering effect of the two spring rods 205 can prevent the first hydraulic cylinder 203 from extending too far and damaging the control cabinet.

[0033] In this embodiment, the water tank 201, the frame 202, the first hydraulic cylinder 203, the base block 204, the spring rod 205, and the pressure block 206 together constitute the first detection component 2.

[0034] In this embodiment, a second detection component 3 is installed on the base 1. The second detection component 3 consists of a second hydraulic cylinder 301, a cover plate 302, and an air inlet pipe 303. Four second hydraulic cylinders 301 are fixed on the top surface of the base 1. The extended ends of the four second hydraulic cylinders 301 are all fixed on the bottom surface of the cover plate 302. The cover plate 302 is located directly above the water storage tank 201. When the four second hydraulic cylinders 301 retract, the cover plate 302 is fastened to the water storage tank 201.

[0035] In this embodiment, an air inlet pipe 303 is welded to the top surface of the cover plate 302. A valve is installed on the air inlet pipe 303. When further testing the control cabinet, the exhaust pipe of the external air supply pump is connected to the air inlet pipe 303, and the valve and air supply pump are opened. At this time, the gas enters the water storage tank 201 through the air inlet pipe 303. By increasing the pressure in the water storage tank 201, the leakage of the control cabinet can be detected.

[0036] In this embodiment, the cover plate 302 has a stepped structure. The outer wall of the lower half of the cover plate 302 contacts the inner wall of the water storage tank 201, and the stepped part of the cover plate 302 contacts the top surface of the water storage tank 201. During use, the stepped structure of the cover plate 302 can improve the sealing performance between the cover plate 302 and the water storage tank 201, and avoid air leakage at the cover plate 302 that would affect the detection accuracy.

[0037] In this embodiment, an auxiliary component 4 is installed on the base 1. The auxiliary component 4 consists of a sliding frame 401, a mounting frame 402, a detection probe 403, a mounting block 404, a first motor 405, a threaded rod 406, a guide rod 407, a placement plate 408, a limiting seat 409, a protrusion 410, and a toggle rod 411. Two sliding frames 401 are symmetrically welded to the top surface of the base 1. A mounting frame 402 slides on the two sliding frames 401. The mounting frame 402 has a concave structure, and the detection probe 403 is installed in a linear array on the top surface of the inner wall of the mounting frame 402.

[0038] In this embodiment, a mounting block 404 is fixed on the right side of the top surface of the base 1, and a first motor 405 is fixed on the left end face of the mounting block 404. A threaded rod 406 is fixed on the output shaft of the first motor 405, and the threaded rod 406 is threadedly connected to the mounting frame 402. When the control cabinet is tested, the control cabinet is placed below the detection probe 403, and the first motor 405 is driven to rotate back and forth. The first motor 405 drives the threaded rod 406 to rotate back and forth. Under the reciprocating drive of the threaded rod 406, the mounting frame 402 and the detection probe 403 move back and forth left and right, thus realizing the reciprocating test of the control cabinet.

[0039] In this embodiment, four stepped shaft-shaped guide rods 407 are welded to the top surface of the base 1. A placement plate 408 slides on the four guide rods 407. A U-shaped limiting seat 409 is welded to the top surface of the placement plate 408. The limiting seat 409 is located below the detection probe 403. During the test, the control cabinet is placed on the placement plate 408. It is necessary to ensure that the control cabinet is located inside the limiting seat 409. During the test, the limiting seat 409 can limit the control cabinet and prevent the control cabinet from shifting and falling.

[0040] In this embodiment, the bottom surface of the placement plate 408 is welded with protrusions 410 in a linear array, and the protrusions 410 are semi-cylindrical structures. An L-shaped actuating rod 411 is welded to the rear end face of the inner wall of the mounting bracket 402. The upper end of the actuating rod 411 contacts the bottom surface of the placement plate 408. When the actuating rod 411 moves left and right with the mounting bracket 402, the actuating rod 411 and the protrusions 410 are in continuous contact. When the actuating rod 411 moves left and right with the mounting bracket 402, the continuous actuation of the protrusions 410 by the actuating rod 411 can generate vibration. At this time, the detection after the control cabinet is transported can be simulated, thus expanding the detection range.

[0041] In this embodiment, a drive assembly 5 is installed on the mounting block 404. The drive assembly 5 consists of a second motor 501 and a toggle block 502. A second motor 501 is fixed on the right end face of the mounting block 404, and a toggle block 502 is fixed on the output shaft of the second motor 501. The toggle block 502 is located below the placement plate 408. When the second motor 501 rotates, the toggle block 502 elastically contacts the bottom end face of the placement plate 408. During the detection process, the second motor 501 is driven to rotate. Under the continuous toggle of the placement plate 408 by the toggle block 502, the placement plate 408 is continuously vibrated. At this time, the detection of the control cabinet under vibration can be realized, thus expanding the detection range.

[0042] Working principle: The control cabinet is placed inside the water tank 201. The first hydraulic cylinder 203 extends, causing the pressure block 206 to move downwards. The pressure block 206 compresses the control cabinet, submerging it in the water tank 201. Observe for any bubbles. For further testing, connect the exhaust pipe of the external air pump to the inlet pipe 303, and open the valve and air pump. Gas enters the water tank 201 through the inlet pipe 303, increasing the pressure inside the tank and detecting leaks. When not testing for liquid leakage, place the control cabinet below the detection probe 403 and drive... The first motor 405 reciprocates, driving the threaded rod 406 to reciprocate. Under the reciprocating drive of the threaded rod 406, the mounting bracket 402 and the detection probe 403 move back and forth, thus realizing the reciprocating detection of the control cabinet. When the actuating rod 411 moves left and right with the mounting bracket 402, the continuous actuation of the protrusion 410 by the actuating rod 411 can generate vibration, thus simulating the detection of the control cabinet after transportation. After the actuating rod 411 is damaged, the second motor 501 is driven to rotate. Under the continuous actuation of the placement plate 408 by the actuating block 502, the placement plate 408 is continuously vibrated, thus realizing the detection of the control cabinet under vibration.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
