[0026] Further, the installation mechanism further includes two fixing plates 10 and two gaskets 11. The two fixing plates 10 are respectively arranged on the left and right inner walls of the detection water tank 4. Two rectangular grooves 12 are respectively formed on the surfaces of the two fixing plates 10 away from each other. The lower ends of the two rectangular grooves 12 are both open. Two third hydraulic expansion rods 13 are fixedly installed inside each of the four rectangular grooves 12. The opposite ends of the third hydraulic expansion rods 13 are fixedly connected to the left and right inner walls of the detection water tank 4. The two gaskets 11 are respectively fixedly installed on the adjacent surfaces of the two fixing plates 10. A connection groove 20 is formed on the left surface of the detection table 1.

[0027] Further, two water level sensors 14 are installed corresponding to each other on the left and right inside the detection water tank 4. The two water level sensors 14 are both electrically connected to the controller 3.

[0028] Further, the hydraulic system oil drain valve is clamped by the two clamping plates 9 and sent into the interior of the detection water tank 4, and is fixed by the two fixing plates 10, so that the gasket 11 seals it, thereby reducing the installation difficulty of the hydraulic system oil drain valve, improving the installation efficiency of workers, and thus improving the use efficiency of the device.

[0029] Further, a first air duct 15 is slidably installed on the inner wall of the connection groove 20. The right end of the first air duct 15 extends to the right surface of the left fixing plate 10 and continues to extend to the right surface of the gasket 11. A sealing ring 21 is fixedly installed on the inner wall of the connection groove 20.

[0030] Further, an installation groove 18 is formed inside the left fixing plate 10 corresponding to the position of the first air duct 15. A one-way valve 19 is fixedly installed on a section of the first air duct 15 located inside the installation groove 18.

[0031] Further, an air pump 16 is placed on the left surface of the detection table 1. The air outlet end of the air pump 16 is fixedly installed with a second air duct 17. The end of the second air duct 17 away from the air pump 16 extends into the connection groove 20 and is in contact with the left end of the first air duct 15.

[0032] Further, the hydraulic system oil drain valve is sealed by the two gaskets 11, and then the first air duct 15 is used to ventilate the inside of the hydraulic system oil drain valve, so that the gas or water inside the hydraulic system oil drain valve is discharged from the air leakage position of the hydraulic system oil drain valve, resulting in a rise in the water level or the generation of bubbles, thereby performing airtightness detection on it, thus improving the detection efficiency of the device and the use efficiency of the device.

[0033] Working principle: When using this detection device to detect the sealing performance of the hydraulic system drain valve, the hydraulic system drain valve can be placed between two clamping plates 9. Then, two second hydraulic telescopic rods 8 fixedly connected to the two clamping plates 9 are started. The telescopic ends of the two second hydraulic telescopic rods 8 drive the two clamping plates 9 to approach each other, clamping the hydraulic system drain valve located between the two clamping plates 9. Then, the motor 5 is started through the controller 3. The output end of the motor 5 rotates, driving the first hydraulic telescopic rod 6 fixedly connected to the output end of the motor 5 to rotate, so that the second U-shaped plate 7 fixedly connected to the telescopic end of the first hydraulic telescopic rod 6 rotates, causing the two second hydraulic telescopic rods 8 and the two clamping plates 9 fixedly installed on the second U-shaped plate 7 to rotate, thereby rotating the hydraulic system drain valve clamped between the two clamping plates 9. After rotating 90 degrees, the motor 5 stops. At this time, the first hydraulic telescopic rod 6 is started, and the telescopic end of the first hydraulic telescopic rod 6 moves downward, driving the second U-shaped plate 7 fixedly connected to its telescopic end to move downward, so that the hydraulic system drain valve between the two clamping plates 9 moves synchronously, and the hydraulic system drain valve enters the interior of the detection water tank 4 and reaches between the two fixing plates 10. At this time, the third hydraulic telescopic rods 13 on the mutually remote surfaces of the two fixing plates 10 are started, so that the two fixing plates 10 and the sealing gasket 11 approach each other. The first air duct 15 fixedly installed on the left fixing plate 10 moves accordingly. The right end of the first air duct 15 enters the interior of the hydraulic system drain valve, and the left end of the first air duct 15 slides out from the interior of the connection groove 20, and the sealing ring 21 seals between the connection groove 20 and the first air duct 15 to prevent water from leaking out of the connection groove 20. When the two fixing plates 10 clamp the hydraulic system drain valve and seal it through the two sealing gaskets 11, the water level at this time is detected by the two water level sensors 14. Then, the air pump 16 is started. The air pump 16 inflates the interior of the first air duct 15 through the second air duct 17 and enters the interior of the hydraulic system drain valve through the one-way valve 19. When the internal air pressure reaches a certain level, the inflation stops. Because when the hydraulic system drain valve enters the interior of the detection water tank 4, part of the water will fill the interior of the hydraulic system drain valve. When the two ends of the hydraulic system drain valve are sealed through the sealing gasket 11 and the interior of the hydraulic system drain valve is inflated through the first air duct 15, if there is a leakage in the hydraulic system drain valve, the water or gas inside it will leak out from the leakage position, resulting in a rise in the water level or the generation of bubbles in the water, so that the sealing performance of the hydraulic system drain valve can be detected, reducing the installation difficulty for workers and thus reducing the labor intensity of workers.
