Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] An embodiment of the present utility model, as Figure 1 and Figure 2 As shown, the bottom of the frame is provided with organic feet and movable casters located inside the machine feet to support the entire equipment and prevent shock. A water tank 3 is provided on the frame 1 at the front and bottom of the control cabinet 2. A vertical lifting mechanism 5 is installed on the outer side of the water tank 3. The lifting mechanism 5 is connected to the product detection platform 52 through a lifting bracket 51. A protective net 4 is provided on the top of the frame 1 cover plate on both sides of the lifting mechanism 5. A water level detection mechanism 6 is installed on the side of the rear of the product detection platform 52 near the control cabinet 2. A low-pressure gas pressure detection mechanism 9 is provided in the frame 1 behind the water tank 3 and is located below the control cabinet 2. There is a high-pressure gas detection system 10 inside the control cabinet. The compressed air detection system 10 includes a nitrogen pressure reducing valve connected to an external nitrogen tank, a high-pressure one-way valve, a high-pressure pressure gauge, a high-pressure solenoid valve pressure transmitter and other components. 5MPa high-pressure nitrogen is filled into the product to detect whether the product is leaking. An electrical cabinet door and a water cabinet door are installed on the back of the control cabinet 2. A lighting mechanism is provided on the frame 1. The lifting height is infinitely controlled by a laser displacement sensor, and the water level height is automatically detected to achieve automatic water replenishment and replacement, increase underwater lighting, and enhance the bubble observation effect. The detection device can not only ensure the detection quality, but also can simultaneously complete the sealing performance detection of valve bodies of various different models, greatly improving the detection efficiency.
[0022] like Figure 2 and Figure 4As shown, the lifting mechanism 5 includes a lifting cylinder 53 installed between the water tank 3 and the cover plate of the frame 1. Optical axes 54 are installed on both sides of the lifting cylinder 53. The output end of the top of the lifting cylinder 53 is connected to the lifting bracket 51. The lifting cylinder 53 is connected to the low-pressure air pressure detection mechanism 9 to provide a pressure of 0.4MPa~0.6MPa. Figure 6 As shown, a laser displacement sensor 55 is installed on the frame 1 outside the optical axis 54 to achieve stepless control of the lifting height. Compared with the traditional pad control accuracy, the lifting mechanism sends the product out of the water and into the water, and calls relevant parameters according to the size of the product to control the lifting height.
[0023] like Figure 3 As shown, the water level detection mechanism 6 includes a liquid level detector 61 installed in the water tank 3, and a water adding pump 62 and a water extraction pump 63 are installed in the frame 1 behind the water tank 3.

[0026] like Figure 5 As shown, an eye-protection lawn 31 is provided in the water tank 3 below the product inspection platform 52. The eye-protection lawn can block some larger impurities from entering the pump body, and at the same time can reduce the fatigue of the staff's eyes caused by long-term use of eyes, and cooperate with the lighting mechanism to make the bubble observation effect more obvious.
[0027] like Figure 4As shown, the surface of the control cabinet 2 is installed with a display screen 21, a buzzer indicator light 22, a test pressure display instrument 23 and a liquid level display instrument 24 from left to right. The buzzer indicator lights are respectively arranged above the test pressure display instrument 23 to provide a limit alarm. A pressure total gauge 25 is arranged above the test pressure display instrument 23. The pressure total gauge 25 displays the size of the intake pressure. The test pressure display instrument 23 displays the size of the pressure in the valve body of the test product. The test pressure display instrument 23 is provided with two groups corresponding to two groups of test products respectively. The high-pressure gas detection system connection air pipe passes through the hole in the front of the control cabinet and is connected to the test product. The pressure information of the test product is displayed on the test pressure display instrument 23 on the corresponding side, which is convenient for the staff to observe the pressure changes. A waterproof button switch 26 is provided on the side of the water tank 3 away from the control cabinet 2 for manual operation and control.
[0028] The working principle of this embodiment is as follows: the lifting mechanism is controlled to raise the product inspection platform out of the water, the product to be inspected is placed on the product inspection platform and connected to the ventilation pipe of the air pressure detection mechanism, the product inspection platform is lowered below the water surface according to the model of the product, the lighting mechanism is always on, and the high-pressure gas detection system fills the product with 5MPa high-pressure nitrogen to detect whether the product is leaking. The staff observes the position of the bubbles generated by the underwater product leakage, and observes the pressure, liquid level height and other parameter information on the panel in front of the control cabinet.
