Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning pipeline detection, and particularly relates to a leakage warning device for an air-conditioning pipeline. Background Technique

[0002] In recent years, with the rise of global temperature and the significant improvement of people's living standards, air-conditioning equipment has gradually become one of the essential household appliances. With the increasingly fierce market competition, the working efficiency and safety of air conditioners have increasingly become one of the main factors affecting the core competitiveness of products. To ensure the airtightness and reliability of air-conditioning pipes, airtightness detection is required after the pipe fittings are welded. The existing technology is to submerge the weld of the air-conditioning pipe underwater, then block one end of the air-conditioning pipe with a plug and ventilate the other end to check if there are bubbles emerging from the weld. This detection method requires the pipe fittings already installed on the finished product to be disassembled for detection first, which is inconvenient for detection and has relatively low detection efficiency.

[0003] After retrieval, the Chinese patent application number is: 202220201832.X, which discloses a pipeline leakage detection device for an air conditioner. Aiming at the problems of inconvenient detection and low detection efficiency when detecting the airtightness of an air-conditioning pipe, the following scheme is proposed. It includes an arc-shaped block, a pressing mechanism is arranged on the outer surface of the arc-shaped block in a fitting manner, and a detection mechanism communicated with a cavity is arranged at the top of the arc-shaped block; in the utility model, the arc-shaped block and the outer surface of the air-conditioning pipeline are pressed tightly through the pressing mechanism, so that the sealing rubber strip at the bottom of the arc-shaped block undergoes elastic deformation to fill and seal the gap between the bottom of the arc-shaped block and the outer surface of the air-conditioning pipeline, preventing the gas leaked from the air-conditioning pipeline from escaping. If there is a leak in the area to be detected of the air-conditioning pipeline, the leaked gas enters the cavity through the ventilation hole and then enters the detection mechanism for detection and display. However, there are the following problems: the device needs to be installed through multiple bolts, the operation is cumbersome, and the device cannot actively give a leakage warning. Content of the Utility Model

[0004] The utility model provides a leakage warning device for an air-conditioning pipeline, aiming to solve the problems in the prior art that the device needs to be installed through multiple bolts, the operation is cumbersome, and the device cannot actively give a leakage warning.

[0005] The present utility model is realized as follows. A leakage warning device for an air-conditioning pipeline includes an upper sleeve plate and a lower sleeve plate. An installation plate is fixedly connected to the outer wall of the upper sleeve plate, and a plug piece is fixedly connected to the outer wall of the installation plate. Barbs are arranged on the outer wall of the plug piece, and an installation block is fixedly connected to the outer wall of the lower sleeve plate. A limiting hole matching the plug piece is formed in the upper surface of the installation block. A clamping block is fixedly connected to the outer wall of the upper sleeve plate, and a clamping groove matching the clamping block is formed in the outer wall of the lower sleeve plate. Sealing rubber half-rings are respectively fixedly connected to the inner walls of the upper sleeve plate and the lower sleeve plate. A glass tube is communicated with the outer wall of the upper sleeve plate. A controller, a pressure sensor, a battery, and a warning lamp are respectively fixedly connected to the inner wall of the glass tube. The pressure sensor, the battery, and the warning lamp are electrically connected to the controller.

[0006] Preferably, a sealing gasket is arranged on the outer wall of the upper sleeve plate, and the sealing gasket is located between the upper sleeve plate and the lower sleeve plate.

[0007] Preferably, a rubber gasket is arranged on the outer wall of the installation plate.

[0008] Preferably, an external threaded tube is communicated with the lower surface of the glass tube, and an internal threaded hole matching the external threaded tube is formed in the outer wall of the upper sleeve plate.

[0009] Preferably, anti-slip lines are arranged on the outer wall of the glass tube.

[0010] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0011] By sleeving the upper sleeve plate and the lower sleeve plate on the outer wall of the welded joint of the air-conditioning pipeline and inserting the plug piece into the limiting hole on the installation block, the upper sleeve plate and the lower sleeve plate can wrap the welded joint of the pipeline, which facilitates the installation of the device on the pipeline. Through the sealing rubber half-rings, the gap between the pipeline and the device can be sealed, improving the tightness of the device on the outer wall of the pipeline. When leakage occurs at the welded joint of the pipeline, the air pressure in the glass tube will increase. The pressure sensor detects the air pressure in the glass tube, the glass tube sends a signal to the controller, the controller receives the signal from the glass tube, and the controller powers the warning lamp, causing the warning lamp to emit a flashing light, actively reminding personnel that there is leakage in the pipeline.
