[0002] As a high-quality, efficient and clean energy, natural gas has gradually become the dominant gas source for urban gas, promoting social and economic development and reducing environmental pollution. In cities, as more and more residential buildings use natural gas and the scope becomes wider and wider, once a natural gas leak occurs in a residential building, especially when a natural gas leak occurs in a residential building late at night, it is often easy to cause serious safety accidents. Therefore, special natural gas leak detection tools are needed to promptly detect the leak point and then carry out timely repairs to prevent accidents.

[0003] According to a natural gas leak detection device proposed in Chinese patent CN115493763A, the device is provided with a bottom cover and a top cover, and the bottom cover and the top cover can be placed at a pipeline position prone to natural gas leakage, so that the natural gas pipeline is wrapped. By arranging a methane sensor, a controller, and an alarm in the top cover of the device, the leaked natural gas can be detected immediately and the alarm can be triggered to inform the maintenance personnel that there is a natural gas leak at that location and to perform maintenance in a timely manner.

[0004] However, there are still some shortcomings in this patent. In this device, the bottom cover and the top cover are fixedly installed on the outer wall of the natural gas pipeline, and the methane sensor is used to detect whether the natural gas is leaking. However, since the position of the methane sensor is always fixed, during the detection of the natural gas pipeline, it is easy to cause the local position of the natural gas pipeline to fail to be detected in time and cause leakage, posing a certain threat to the life safety of residents. For this reason, we propose a natural gas leak detection and adjustment device. Summary of the invention

The wall is fixedly connected with a gear 418. By setting up a detection component 41, when a natural gas leak detection process is required, the operator turns on the forward and reverse motor 411 to cause the screw rod 412 to rotate. During the rotation of the screw rod 412, the sleeve block 4116 will move. During the movement of the sleeve block 4116, the cross bar 4114 will move. When the cross bar 4114 moves, it will cause the fixed seat 413 to move. The inner wall of one side of the fixed seat 413 is slidably set on the outer wall of the limit rod 414, so that the fixed seat 413 can move smoothly during the movement, thereby facilitating the adjustment of the lateral detection position of the outer wall of the pipeline, thereby improving the detection effect of natural gas leaks. During the movement of the fixed seat 413, the operator turns on the drive motor 416 to cause the output shaft 417 to rotate. During the rotation of the output shaft 417, the gear 418 will rotate.

[0020] A preferred embodiment of a natural gas leak detection and regulation device provided by the present invention is as follows: Figures 1 to 7As shown: the outer wall of the top cover 1 is provided with a mounting assembly 42, the mounting assembly 42 includes a limit block 421 fixedly connected to the bottom outer wall of the top cover 1, the inner wall of the limit block 421 is slidably connected to a second slider 422, the side wall of the second slider 422 is fixedly connected to the bottom outer wall of the bottom cover 2, the top of the limit block 421 is fixedly connected to a U-shaped block 423, the bottom inner wall of the U-shaped block 423 is threadedly connected to a screw 424, the bottom outer wall of the screw 424 is fixedly connected to an adjusting block 425, the top of the screw 424 is rotatably connected to a rectangular block 426, and the rectangular block 426 is fixedly connected to the bottom outer wall of the bottom cover 2. The outer wall of 26 is slidably connected with the bottom inner wall of the second slider 422. By setting the installation component 42, when the top cover 1 and the bottom cover 2 need to be installed, the operator inserts the second slider 422 into the limit block 421 and pushes the top cover 1 and the bottom cover 2 to close, and then rotates the adjustment block 425 to cause the screw 424 to rotate. During the rotation of the screw 424, the rectangular block 426 will move upward, causing the rectangular block 426 to be embedded in the second slider 422, thereby realizing the limitation of the top cover 1 and the bottom cover 2 after installation.

[0021] Furthermore, the inner wall of the top cover 1 is slidably connected to the natural gas pipeline 3, and the bottom of the natural gas pipeline 3 is slidably connected to the top inner wall of the bottom cover 2. By sleeved the top cover 1 and the bottom cover 2 on the outer wall of the natural gas pipeline 3, it is convenient to detect the outer wall of the natural gas pipeline 3 to avoid hidden dangers of natural gas leakage.

[0022] Furthermore, an alarm light 6 is fixedly connected to the top center of the top cover 1, and a control panel 5 is arranged on the side of the alarm light 6. The bottom of the control panel 5 is fixedly connected to the top of the top cover 1. By setting the alarm light 6, when the detector 4115 detects natural gas leakage on the outer wall of the natural gas pipeline 3, the alarm light 6 will flash to remind the operator to deal with the leaked natural gas.

[0023] Furthermore, an inner wall at one end of the fixing seat 413 is matched with an outer wall of the limiting rod 414 , and an inner wall at the other end of the fixing seat 413 is fixedly connected with an outer wall of the driving motor 416 .

[0024] Furthermore, there are six first sliders 4111, and the six first sliders 4111 are divided into two groups. The two groups of first sliders 4111 are symmetrically distributed along the center plane of the ring gear 419. By setting six first sliders 4111, it is convenient to limit the ring gear 419 and make the ring gear 419 rotate smoothly.

[0025] In addition, one side of the sleeve block 4116 is fixedly connected to the side wall of the cross bar 4114 , and the sleeve block 4116 is located above the limiting rod 414 .

[0026] Working principle: When natural gas leak detection is required, the operator turns on the forward and reverse motor 411 to cause the screw rod 412 to rotate. During the rotation of the screw rod 412, the sleeve block 4116 will move. During the movement of the sleeve block 4116, the cross bar 4114 will move. When the cross bar 4114 moves, it will cause the fixed seat 413 to move. The inner wall of one side of the fixed seat 413 is slidably set on the outer wall of the limit rod 414, so that the fixed seat 413 can move smoothly during the movement, thereby facilitating the adjustment of the lateral detection position of the outer wall of the pipeline. The device improves the detection effect of natural gas leakage. During the movement of the fixed seat 413, the operator turns on the driving motor 416 to cause the output shaft 417 to rotate. During the rotation of the output shaft 417, the gear 418 is driven to rotate. During the rotation of the gear 418, the gear 418 is meshed with the ring gear 419. The support 4113, the connecting rod 4112 and the first slider 4111 limit the ring gear 419, which causes the ring gear 419 to rotate, and causes the detector 4115 to rotate, thereby realizing the circumferential rotation detection around the pipeline. When it is necessary to install the top cover 1 and the bottom cover 2, the operator inserts the second slider 422 into the limit block 421 and pushes the top cover 1 and the bottom cover 2 to close, and then rotates the adjustment block 425 to cause the screw 424 to rotate. During the rotation of the screw 424, the rectangular block 426 will move upward, causing the rectangular block 426 to embed into the second slider 422, thereby limiting the top cover 1 and the bottom cover 2 after installation. After the top cover 1 and the bottom cover 2 are installed, the natural gas pipeline 3 can be closed, and the interior of the top cover 1 and the bottom cover 2 is in a closed state. During the rotation of the ring gear 419, the outer wall of the natural gas pipeline 3 can be fully detected, thereby improving the detection effect of the detector 4115 on the outer wall of the natural gas pipeline 3. When a natural gas leak occurs, the control panel 5 controls the alarm light 6 to work, causing the alarm light 6 to generate an alarm, prompting the operator that a natural gas leak has occurred and that loss must be stopped in time.

Any changes or modifications that are made to the main design concept and spirit of the present invention and have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention.
