Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipeline leak detection technology, specifically to a rapid leak detection device for air conditioning pipelines. Background Technology

[0002] A refrigerant leak detector is a specialized instrument used to detect refrigerant leaks in refrigeration systems (such as air conditioners, refrigerators, and cold storage). It is widely used in refrigeration repair, automotive air conditioning maintenance, and industrial refrigeration equipment maintenance.

[0003] Most existing refrigerant leak detectors require operators to move the probe along the air conditioning ducts. When a leak is detected, the detector alarms. However, in practice, some outdoor air conditioning unit ducts are located on the walls of high-rise buildings. In such cases, operators need to climb to the exterior wall and move the probe along the ducts to detect leaks. This operation is time-consuming and laborious, undoubtedly causing significant inconvenience to air conditioning duct leak detection and creating substantial safety hazards.

[0004] In summary, most existing refrigerant leak detectors require operators to hold the probe tip and move it along the air conditioning ducts, making it inconvenient to perform leak detection at heights. Utility Model Content

[0005] The purpose of this invention is to provide a rapid leak detection device for air conditioning pipelines, so as to solve the technical problem that most existing refrigerant leak detectors require operators to hold the probe tip and move it along the air conditioning pipeline, which is inconvenient for high-altitude operations to detect leaks in air conditioning pipelines.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution: A rapid leak detection device for air conditioning pipes; It includes a leak detector 1 and a leak detector 2, and the leak detector 1 and the leak detector 2 are semi-circular in shape. The two can be assembled into a split ring structure, and one end of the leak detector 1 and the leak detector 2 are rotatably connected. Limiting rods are symmetrically arranged on both sides of the other end of the second leak detector. Traction plates that can engage with the limiting rods are movably arranged on both sides of the other end of the first leak detector. Lifting lugs are symmetrically arranged on both sides of the first and second leak detectors. Adapter seats are symmetrically arranged on both sides of the first and second leak detectors, with the adapter seat located on one side of the lifting lug seat. A threaded shaft is internally threaded into the adapter seat. A hinge seat is provided at one end of the threaded shaft. A telescopic rod is movably arranged inside the hinge seat.

[0007] Preferably, the leak detector one and the leak detector two are internally equipped with a circuit board, a gas-sensitive semiconductor sensor, and an audible and visual alarm module.

[0008] Preferably, the edges of the leak detector one and the leak detector two are designed with rounded corners.

[0009] Preferably, the inner walls of the leak detector one and the leak detector two are symmetrically provided with several sets of equally spaced detection holes.

[0010] Preferably, the inner walls of the leak detector one and the leak detector two are symmetrically provided with three sets of equidistant movable grooves.

[0011] Preferably, the interior of the movable groove is provided with rotatable ball bearings.

[0012] Preferably, the outer side of the adapter is rotatably provided with a fixing bolt for fixing the threaded shaft.

[0013] Preferably, the second leak detector is provided with a magnetic plug at one end of a limiting rod.

[0014] Preferably, the leak detector has a slot at one end with a traction plate that matches the magnetic plug.

[0015] Preferably, the bottom wall of the insertion slot is provided with a magnetic pad that magnetically attracts and fixes the insertion slot.

[0016] The beneficial effects of this utility model are: 1. In this utility model, the leak detector 1 and the leak detector 2 are separate semi-circular units. When leaking air conditioning pipes installed at high altitudes, the workers can assemble the leak detector 1 and the leak detector 2 together and place them on the outside of the air conditioning pipes. Then, the limiting rod and the traction plate are used to lock the two together. This allows the device to be quickly installed on the air conditioning pipes without disassembling the pipes, which improves the leak detection efficiency. Then, the device is moved along the air conditioning pipes by the telescopic rod. The workers do not need to climb to the outer wall, which greatly reduces the difficulty of the leak detection work and eliminates safety hazards. 2. In this utility model, when the leak detector one and the leak detector two are closed, the magnetic plug is inserted into the plug slot and forms a magnetic attraction fixation with the magnetic pad, which further enhances the stability of the device closure. The ball bearings that are rotated on the inner wall of the leak detector one and the leak detector two can reduce the friction between the device and the air conditioning pipe, making it convenient for the device to move on the pipe and for leak detection at different locations.

They can be assembled into a split ring structure, and one end of the leak detector 1 and the leak detector 2 are rotatably connected. Limiting rods 6 are symmetrically arranged on both sides of the other end of the leak detector 2. Traction plates 7 that can engage with the limiting rods 6 are movably arranged on both sides of the other end of the leak detector 1. Lifting lugs 8 are symmetrically arranged on both sides of the leak detector 1 and the leak detector 2. Adapter seats 9 are symmetrically arranged on both sides of the leak detector 1 and the leak detector 2, and the adapter seat 9 is located on one side of the lifting lug seat 8. A threaded shaft 11 is threadedly connected inside the adapter seat 9. A fixing bolt 10 for fixing the threaded shaft 11 is rotatably arranged on the outside of the adapter seat 9. A hinge seat 12 is provided at one end of the threaded shaft 11. A telescopic rod 13 is movably arranged inside the hinge seat 12.

[0022] Leak detector 1 and leak detector 2 are connected at one end by a rotatable connection, allowing them to rotate relative to each other to open or close. This facilitates the worker's installation of the entire device on the outside of the air conditioning duct. When leak detector 1 and leak detector 2 are assembled together, the traction plate 7 engages with the limiting rod 6, securing leak detector 1 and leak detector 2. This ensures that leak detector 1 and leak detector 2 do not easily detach when the device moves along the outer wall of the air conditioning duct. The lifting lug 8 can be used to install ropes for traction. The telescopic rod 13 is threaded onto the device, helping the worker drive the device along the air conditioning duct. The telescopic rod 13 can rotate within the hinge seat 12, thus driving the device to move in different directions. The telescopic rod 13 can also be extended or retracted to adjust its length, meeting the leak detection needs of air conditioning ducts of different lengths. The fixing bolt 10 is used for... The threaded shaft 11 is fixed to prevent it from loosening during use. When using the device, first open the leak detector 1 and leak detector 2 and place them on the air conditioning pipe. Then close the leak detector 1 and leak detector 2 to engage the limiting rod 6 with the traction plate 7. At the same time, the magnetic plug 14 is inserted into the insertion slot 15 and forms a magnetic attraction with the magnetic pad 16 to fix it. The installation of the device is completed. Then start the leak detector 1 and leak detector 2. Install the end of the telescopic rod 13 on the hinge seat 12 and fix it with the fixing bolt 10. Tie the rope to the lifting lug 8. Drive the device along the air conditioning pipe by adjusting the length of the telescopic rod 13. When the device detects a leak, the device alarms. When the telescopic rod 13 becomes loose and detaches from the device during the leak detection process, the rope on the lifting lug 8 plays a traction role and can retrieve the device to prevent it from falling from a height.

[0023] In this embodiment, specifically, the leak detector 1 and the leak detector 2 are equipped with a circuit board, a gas-sensitive semiconductor sensor, and an audible and visual alarm module. The three are electrically connected. The circuit board is used to control the operation of the entire device. The gas-sensitive semiconductor sensor is used to detect whether there is a refrigerant leak in the air around the air conditioning pipe. When a leak is detected, the audible and visual alarm module will issue an audible and visual alarm signal to remind the operator.

The movable grooves 4 are rotatably provided with ball bearings 5. The ball bearings 5 ​​can reduce the friction between the device and the air conditioning pipe, facilitate the movement of the device on the pipe, and facilitate leak detection at different locations.

[0027] In this embodiment, specifically, the second leak detector 2 is provided with a magnetic plug 14 at one end of the limiting rod 6, and the first leak detector 1 is provided with a plug groove 15 at one end of the traction plate 7 that matches the magnetic plug 14. The bottom wall of the plug groove 15 is provided with a magnetic pad 16 that forms a magnetic attraction fixation with the plug groove 15. When the first leak detector 1 and the second leak detector 2 are closed, the magnetic plug 14 is inserted into the plug groove 15 and forms a magnetic attraction fixation with the magnetic pad 16, further enhancing the stability of the device closure.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] The working principle of this utility model is as follows: When using the device, first open the leak detector 1 and the leak detector 2 and place them on the air conditioning pipe. Then close the leak detector 1 and the leak detector 2, so that the limiting rod 6 and the traction plate 7 are engaged. At the same time, the magnetic plug 14 is inserted into the plug slot 15 and forms a magnetic attraction fixation with the magnetic pad 16, thus completing the installation of the device. Then start the leak detector 1 and the leak detector 2, install the end of the telescopic rod 13 on the hinge seat 12 and fix it with the fixing bolt 10, tie the rope to the lifting lug seat 8, and drive the device to move along the air conditioning pipe by adjusting the length of the telescopic rod 13.
