[0024] EMBODIMENT

[0025] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the technical scheme in the embodiment of the application effectively solves the technical problem that the water meter control box is clamped by the sliding block, the water meter control box is buried in the solution pool, the sliding block is arranged on the inner wall of the solution pool, the sliding block moves in the vertical direction, the distance between the two sliding blocks cannot be adjusted, and the water pump control box of different specifications cannot be fixed. The overall idea is as follows:

[0026] In view of the problems in the prior art, the utility model provides a kind of air tightness tester of intelligent water meter control box, including control box body 11 and test frame 12, the side end of test frame 12 is equipped with pump and smoke generator, smoke generator generates smoke, and the force generated by pump is used to deliver smoke to the inside of hose 14;

[0027] Two sealing assemblies, two sealing assemblies are arranged on the side wall of test frame 12, each sealing assembly includes positioning plate 13 and sealing sleeve 21, the side end of each positioning plate 13 is fixedly installed with guide plate 18, the side end of each guide plate 18 is fixedly installed with positioning sleeve 19, pushing force is generated on two guide plates 18, two guide plates 18 slide along the side end of test frame 12, and the distance between positioning plate 13 can be expanded or reduced, the distance between two positioning plates 13 can be adjusted, different sizes of control box body 11 can be fixed and clamped, and the air tightness of control box body 11 is tested.

[0028] The interior of the test frame 12 is rotatably provided with two rotating push rods 17 which are in abutment with the positioning sleeves 19. The top end of the test frame 12 is provided with a knob handle 16. The end of the knob handle 16 is connected with the two rotating push rods 17 through bevel gears. By rotating the knob handle 16, the end of the knob handle 16 drives the two rotating push rods 17 to rotate in the interior of the test frame 12. At the same time, the end of the rotating push rod 17 is in abutment with the interior of the positioning sleeve 19. The rotating push rod 17 rotates to push the positioning sleeve 19 to move in the interior of the test frame 12, thereby generating a pushing force on the guide plate 18. At the same time, the screw thread angle of the rotating push rod 17 and the positioning sleeve 19 is smaller than the friction angle. The rotating push rod 17 rotates to drive the positioning sleeve 19. When the rotating push rod 17 stops rotating, the rotating push rod 17 and the positioning sleeve 19 can be self-locked.

[0029] Each sealing sleeve 21 is made of silicone rubber. The interior of each sealing sleeve 21 is provided with a pipe 22. By positioning the plate 13, the plate 13 drives the sealing sleeve 21 to be in abutment with the interface of the water meter control box. By extruding the sealing sleeve 21, the tightness of the connection is increased. At the same time, the plate 13 pushes the pipe 22 to be inserted into the interior of the water meter control box, thereby conveying the smoke to the interior of the control box body 11. Whether the surface of the control box body 11 leaks smoke is observed.

[0030] The interior of each pipe 22 is fixedly provided with a support strip 23. The side end of each support strip 23 is provided with a pressure sensing head 24. The end of the pipe 22 is provided with the support strip 23 and the pressure sensing head 24. The pressure sensing head 24 can detect the pressure value in the interior of the water meter control box. The detected data is transmitted to the control end through the connecting line 15, thereby controlling the opening and closing of the pump.

[0031] The side end of each positioning plate 13 is fixedly provided with a hose 14. The top end of the hose 14 is connected with the end of the pipe 22. The hose 14 directly conveys the smoke to the interior of the control box body 11.

[0032] The top end of each positioning plate 13 is fixedly provided with a connecting line 15. One end of each connecting line 15 penetrates through the top end of the positioning plate 13 and is connected with the pressure sensing head 24. The end of the connecting line 15 is directly connected with the control end, thereby transmitting the signal generated by the pressure sensing head 24.

[0033] Working principle:

[0034] Firstly, the control box body 11 to be tested is placed on the test frame 12, and the distance between the two positioning plates 13 is adjusted by rotating the knob handle 16 at the top end of the test frame 12 according to the size of the control box body 11. The knob handle 16 is connected with the two rotating push rods 17 through bevel gears, and when the knob handle 16 is rotated, the two rotating push rods 17 are driven to rotate inside the test frame 12. Since the rotating push rods 17 are connected with the positioning sleeves 19 inside, and the thread angle of the rotating push rods 17 and the positioning sleeves 19 is smaller than the friction angle, the rotating push rods 17 push the positioning sleeves 19 to move inside the test frame 12, thereby generating a pushing force on the guide plates 18, so that the two guide plates 18 slide along the side end of the test frame 12, and the positioning plates 13 are moved to achieve the clamping of the control box body 11 of different sizes.

[0035] Secondly, during the movement of the positioning plates 13, the sealing sleeve 21 fixed on the side end of the positioning plates 13 is connected with the interface of the water meter control box. Since the sealing sleeve 21 is made of silicone rubber material and has a certain elasticity, the sealing sleeve 21 is extruded during the connection to increase the tightness of the connection. At the same time, the positioning plates 13 push the insertion pipe 22 to be inserted into the water meter control box, so as to prepare for the delivery of smoke into the control box body 11. The support bar 23 fixedly installed inside the insertion pipe 22 is provided with a pressure sensing head 24 at the side end, which detects the pressure value inside the water meter control box in real time. The detected data is transmitted to the control end through the connecting line 15, and the control end determines whether the pump needs to be opened or closed according to the received pressure data.

[0036] The smoke generator installed at the side end of the test frame 12 generates smoke, and the pump is started to generate a force to deliver the smoke into the hose 14, and the hose 14 directly delivers the smoke to the insertion pipe 22 and then to the control box body 11. During this process, it is observed whether there is smoke leakage on the surface of the control box body 11. If there is smoke leakage, it indicates that the air tightness of the control box body 11 is poor. If there is no smoke leakage, the air tightness is good.

[0037] Finally, it should be pointed out that the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
