[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a sealing detection device for a high-airtightness liquid receiver for an air conditioning compressor, including a water tank 1. A controller 2 is installed at the front end of the water tank 1, and a placement plate 3 is installed above the controller 2. Fixed grooves 4 are provided through both ends of the placement plate 3, and multiple fixed grooves 4 are distributed at equal intervals inside the placement plate 3. A side plate 5 is installed at the rear end of the placement plate 3. A sensor 6 is installed above one end of the interior of the water tank 1. An infrared emitter 7 is installed above the front end of the side plate 5. An mounting plate 8 is installed on one side of the infrared emitter 7 at the front end of the side plate 5. An air supply pipe 9 is installed inside the mounting plate 8. One end of the air supply pipe 9 is connected to one end of an external air pump. A moving mechanism is provided at the rear end of the interior of the water tank 1, and a positioning mechanism is provided at the front end of the side plate 5.

[0020] The positioning mechanism includes a rotating wheel 10, a threaded rod 11, a threaded sleeve 12, a connecting rod 14, and a clamping plate 15. The rotating wheel 10 is mounted on one side of a side plate 5. The threaded rod 11 is installed inside the side plate 5. One end of the rotating wheel 10 is connected to one end of the threaded rod 11. The threads at both ends of the threaded rod 11 are in opposite directions. Threaded sleeves 12 are symmetrically arranged on the outer side wall of the threaded rod 11. A connecting rod 14 is installed at the front end of the threaded sleeve 12. A clamping plate 15 is installed at the front end of the connecting rod 14. A limiting plate 13 is installed between the threaded sleeve 12 and the connecting rod 14. The limiting plate 13 can control the threaded sleeve 12. 2. Limiting treatment is performed. The clamping plate 15 is arc-shaped, and the two clamping plates 15 are symmetrically distributed about the central axis of the side plate 5. In use, the liquid storage tank is placed at the top of the fixed groove 4, and then the rotating wheel 10 drives the threaded rod 11 to rotate, thus driving the threaded sleeve 12 to move. Under the limitation of the limiting plate 13, the threaded sleeve 12 drives the clamping plate 15 to move, and the two clamping plates 15 are used to position the liquid storage tank, making the liquid storage tank more stable during testing. Therefore, the airtightness test result of the liquid storage tank is more accurate, which greatly improves the practicality of the device in use.

[0021] The moving mechanism includes a servo motor 16, a screw 17, a screw sleeve 18, and a limiting structure. The servo motor 16 is installed at the rear end of the top of the water tank 1, and the screw 17 is installed inside the water tank 1. The output end of the servo motor 16 is connected to one end of the screw 17. A screw sleeve 18 is provided on the outer wall of the screw 17, and one end of the screw sleeve 18 is connected to one end of the side plate 5. In use, the servo motor 16 is started to drive the screw 17 to rotate, thus driving the screw sleeve 18 to move. Then, under the limiting of the limiting rod 19 and the limiting sleeve 20, the screw sleeve 18 drives the liquid storage tank to move downward to perform a sealing test on the liquid storage tank, making the liquid storage tank more convenient and faster to test, thereby greatly improving the convenience of the device in use.

[0022] The limiting structure includes a limiting rod 19 and a limiting sleeve 20. The limiting rod 19 is installed on both sides inside the water tank 1. The limiting sleeve 20 is provided on the outer side wall of the limiting rod 19. One end of the limiting sleeve 20 is connected to one end of the side plate 5. The cross-section of the limiting rod 19 is smaller than the cross-section of the limiting sleeve 20. The limiting rod 19 and the limiting sleeve 20 form a sliding structure. In use, the mutual cooperation between the limiting rod 19 and the limiting sleeve 20 can limit the movement of the side plate 5, making the side plate 5 more stable when moving.

[0023] Working principle: The operator first places the storage tank at the top of the fixed groove 4, then rotates the rotating wheel 10 to drive the threaded rod 11 to rotate, thus moving the threaded sleeve 12. Under the limitation of the limiting plate 13, the threaded sleeve 12 drives the clamping plate 15 to move, thereby positioning the storage tank using the two clamping plates 15. Then, one end of the gas pipe 9 is sealed to one end of the storage tank, and gas is introduced into the storage tank. At this time, the servo motor 16 is started to drive the screw 17 to rotate, thus moving the threaded sleeve 18. The threaded sleeve 12 then moves under the limitation of the limiting plate 13. Under the limit of 9 and limit sleeve 20, the liquid storage tank is moved downward by the screw sleeve 18, so that the sensor 6 and infrared emitter 7 work together. Through the cooperation of sensor 6 and infrared emitter 7, it is possible to observe whether there are bubbles in the water. Due to the reflection of light and the different absorption of light by different media, the light intensity received by the photosensitive device can change, thereby causing the output voltage to change. Therefore, if there are bubbles in the water between sensor 6 and infrared emitter 7, controller 2 can distinguish them according to the data received by sensor 6, thereby achieving the purpose of automatic and accurate detection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
