Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline leakage detection, in particular to a gas pipeline leakage detection device. Background Art

[0002] The gas pipeline is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. The gas pipeline has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas blocking. When the gas pipeline is in use, it is necessary to check whether there is a gas leak. Gas pipeline leakage detection is an important task. Its purpose is to promptly discover and deal with pipeline leakage problems to protect people's lives and property.

[0003] For example, a gas pipeline leakage detection device disclosed in Chinese patent CN116817193A can move by rotating the swing rod to make the rubber sleeve close to gas pipelines of different sizes, and the air bags on the front and rear sides can be expanded to abut against the periphery to prevent gas leakage, thereby improving the detection effect. The gas flow is controlled by an air pump, which is convenient and quick. The dust and peeling paint fragments on the periphery of the gas pipeline can be removed by the vibration of the bristles. The upper box body is supported by the push springs on the upper and lower sides and kept balanced, so that the gas box and the electric box can move synchronously. Through the installation between the upper box body and the lower box body, there is no need to disassemble the pipeline to put in the detector, which improves safety.

[0004] Although this structure can clean the paint fragments that fall off the outer wall of the gas pipeline, the operation of the device when clamping the gas pipeline is cumbersome, making the work inconvenient. Therefore, we propose a gas pipeline leakage detection device that can quickly clamp the gas pipeline to improve the convenience of gas pipeline clamping. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The gas pipeline leakage detection device is composed of a clamping assembly as one of its components. When the gas pipeline needs to be detected, the gas pipeline needs to be clamped for detection, and the wheels connected to the outer wall of the horizontal plate are rotated to contact the outer wall of the pipeline. Since the horizontal plate is arranged in an arc shape, the four wheels can stably support the support frame fixedly installed on the top surface of the horizontal plate. At this time, the motor is started to make the rotating rod fixedly installed at the output end of the motor start to rotate, so that the first gear fixedly installed at one end of the rotating rod away from the motor starts to rotate. Since the inner wall of the limiting groove opened on the outer wall of the first gear ring is slidably arranged with the outer wall of the limiting column, and the end of the limiting column is fixedly installed with the outer wall of the support frame, under its restriction, when the first gear is meshed with its first gear ring, it can drive the first gear ring to rotate, so that the first gear ring drives the detection body arranged on the inner side thereof to move accordingly, and when the rotating rod rotates, the first bevel gear fixedly installed on its outer wall rotates accordingly, The second bevel gear meshed with the first bevel gear starts to rotate. Since the rotating column is fixedly installed on the top surface of the support frame, and the interior of the second bevel gear is rotatably connected to the outer wall of the rotating column, under its restriction, the second bevel gear rotates under the action of the meshing of the first bevel gear, and the third bevel gear meshed with the second bevel gear rotates accordingly, so that the sleeve fixedly installed inside the third bevel gear rotates accordingly, and the second gear fixedly installed on the outer wall of the sleeve rotates accordingly. Under the restriction of the limiting ring fixedly installed on the outer wall of the rotating rod, the rotation of the sleeve and the outer wall of the rotating rod is more stable. When the second gear rotates, the second gear ring meshed with it rotates accordingly. Under the restriction of the sliding of the limiting groove opened in the second gear ring and the outer wall of the limiting column, the second gear ring can rotate more stably, so that the first gear ring and the second gear ring rotate in opposite directions to wrap the pipeline in a ring shape, so as to drive the detection body to quickly wrap the pipeline, so as to quickly install and detect the gas pipeline.

[0015] 2. The gas pipeline leakage detection device is composed of a fitting component as one component. When the first gear ring and the second gear ring wrap the gas pipeline in a ring shape, the detection body needs to fit the outer wall of the pipeline. At this time, the telescopic rod can be started to push the arc plate hingedly connected at its end to move toward the outer wall of the pipeline, so that the arc plate is away from the detection body fixedly installed on the outer wall side of the telescopic rod and contacts the pipeline to detect the gas pipeline. Since the arc plate is hingedly connected to the telescopic rod, under its restriction, the arc plate can fit the outer wall of the pipeline more closely. The independently arranged telescopic rod can also be used to detect pipelines with protrusions on the outer wall to increase the scope of detection application. BRIEF DESCRIPTION OF THE DRAWINGS
