[0002] Existing gas leak detection devices are not convenient for detecting various parts of the gas pipeline during use, and the detection is carried out in an open environment, which can easily lead to deviations in the detection results, thereby affecting the subsequent use of the pipeline.

[0004] However, this device has the following drawbacks during use: While the device utilizes detection hoods 1 and 2 to collect leaked gas within the spherical space enclosed by the two hoods, improving the accuracy of detection results, the tubular shape of the gas pipeline makes it difficult to quickly locate the specific location of the gas pipeline leak. To address these drawbacks, we propose a gas leak detection device. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1-6 The utility model provides a technical solution: a gas leak detection device, including: a detection rod, a driving component and a visual detection structure.

[0031] See Figure 1 、 Figure 2 and Figure 6The detection rod includes a hand-held rod 10, and a detection structure arranged at the upper end of the hand-held rod 10. The gas detection structure includes a first semicircular cover 20 and a support frame 21 respectively fixedly mounted on the upper end of the hand-held rod 10, a second semicircular cover 22 rotatably mounted on the inner wall of the support frame 21 through a rotating shaft, a torsion spring 23 arranged on the surface of the rotating shaft for driving the second semicircular cover 22 to merge with the first semicircular cover 20, a mounting cover 24 fixedly mounted on the front face of the first semicircular cover 20, and a gas monitoring probe 25 fixedly mounted on the inner wall of the mounting cover 24.

[0032] The surfaces of the first semicircular cover 20 and the second semicircular cover 22 are both provided with grooves 26 for the gas pipeline to pass through. The interior of the mounting cover 24 is connected to the interior of the first semicircular cover 20. When the gas pipeline is placed in the first semicircular cover 20 and the second semicircular cover 22, the torsion spring 23 can be used to drive the first semicircular cover 20 and the second semicircular cover 22 to merge. At this time, the gas pipeline will be inside the first semicircular cover 20 and the second semicircular cover 22. When the gas pipeline leaks, the gas will gather in the first semicircular cover 20 and the second semicircular cover 22, and the gas monitoring probe 25 will sound an alarm after detecting the gas leak.

[0033] See Figure 1-4 The driving component is arranged on the surface of the hand-held rod 10, and is used to drive the second semi-circular cover 22 to rotate. The driving component includes a connecting frame 40 fixedly mounted on the surface of the second semi-circular cover 22, a pulling rope 41 hinged on the inner wall of the connecting frame 40, a connecting frame 42 fixedly mounted on the surface of the hand-held rod 10, a guide ring 43 fixedly mounted on the surface of the hand-held rod 10, and a pull rod 44 rotatably mounted on the inner wall of the connecting frame 42, one end of the pulling rope 41 passes through the guide ring 43 and is hinged to the surface of the pull rod 44.

[0034] Pulling the pull rod 44 can drive the pulling rope 41 to slide along the inner wall of the guide ring 43, so that the pulling rope 41 can be used to drive the second semicircular cover 22 to rotate and move away from the first semicircular cover 20. At this time, the torsion spring 23 is in an open state, which can facilitate the gas pipeline to enter the first semicircular cover 20 and the second semicircular cover 22, and loosening the pull rod 44 can use the spring force of the torsion spring 23 to reset the second semicircular cover 22, so that the first semicircular cover 20 and the second semicircular cover 22 can be quickly merged, which facilitates the wrapping of the gas pipeline.

[0035] See Figure 2 and Figure 5 The visual detection structure includes a nozzle 30 fixedly mounted on the inner wall of the first semicircular cover 20 and the second semicircular cover 22, and a water supply component arranged on the surface of the handheld rod 10 for supplying water to the nozzle 30.

[0036] The water supply assembly includes a piston cylinder 50 slidably mounted on the surface of the hand-held rod 10, a piston 51 fixedly mounted at the lower end of the hand-held rod 10, a water supply pipe 52 fixedly mounted on the inner wall of the hand-held rod 10, two connecting pipes 53 fixedly mounted at the upper ends of the water supply pipe 52, and a water suction pipe 54 fixedly mounted at the lower end of the piston cylinder 50. The lower end of the piston cylinder 50 is threadedly connected to a water storage cylinder 55, and one end of the water suction pipe 54 extends to the interior of the water storage cylinder 55.

[0037] The ends of the two connecting pipes 53 away from the water supply pipe 52 are fixedly connected to the water inlet ends of the two nozzles 30 respectively, and the lower end of the water supply pipe 52 extends to the interior of the piston cylinder 50. The surfaces of the water supply pipe 52 and the water suction pipe 54 are both provided with one-way valves 56. The one-way valve 56 on the surface of the water supply pipe 52 can prevent the water in the water supply pipe 52 from flowing back into the piston cylinder 50, and the one-way valve 56 on the surface of the water suction pipe 54 can prevent the water in the piston cylinder 50 from flowing back into the water storage cylinder 55.

[0038] First, fill the water storage cylinder 55 with foam liquid, and then pull the piston cylinder 50 downward to drive the piston 51 and the hand-held rod 10 to move upward relative to the piston cylinder 50, so that suction can be generated in the piston cylinder 50, and the foam in the water storage cylinder 55 is sucked into the piston cylinder 50 by the suction pipe 54, and then push the piston cylinder 50 upward, so that the foam in the piston cylinder 50 can be squeezed into the water supply pipe 52, and enter the two nozzles 30 along the two connecting pipes 53 and sprayed out, and the gas pipeline is sprayed. At this time, foam will adhere to the surface of the gas pipeline, and the leaking gas position will emit a steady stream of bubbles, which can be quickly discovered by the operator.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
