[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 3-5 This utility model provides an embodiment of a gas leak detection device for buried gas pipelines, comprising a connecting cover 1, a control component 4 inside the connecting cover 1, a reset component 6 rotatably connected to the surface of the control component 4, an outer cover 5 rotatably connected to one end of the reset component 6, the outer cover 5 being rotatably connected to the control component 4, and the outer cover 5 being slidably connected to the connecting cover 1, a limit component 3 being fixedly connected to the front side of the control component 4, two limit posts 8 being fixedly connected to the inner bottom wall of the connecting cover 1, a connecting block 2 being provided on the surface of the two limit posts 8, the limit component 3 being located behind the connecting block 2, four bolts 7 being threadedly connected inside the connecting block 2, all four bolts 7 being threadedly connected to the connecting cover 1, and an adjustment assembly being provided on the right side of the connecting cover 1.

[0027] Specifically, the connecting cover 1 is made of stainless steel, and a T-shaped groove is provided inside the connecting cover 1 to accommodate the connecting block 2. The surface of the connecting cover 1 is coated with an anti-rust coating to enhance its service life in underground humid and corrosive environments. The control component 4 is designed in a cylindrical shape to facilitate operation and rotation. The control component 4 is made of alloy steel with a smooth surface to ensure that it will not deform or be damaged during frequent operation. The control component 4 and the limiting component 3 are welded together to ensure a firm connection.

[0028] The reset component 6 is a reset spring made of spring steel, which has good elasticity and fatigue resistance. It can maintain a stable elastic restoring force after multiple extension and contraction cycles. The two ends of the reset spring are hinged to the control component 4 and the outer cover 5 to ensure that the connection between the spring and the control component 4 and the outer cover 5 is firm and reliable during the extension and contraction process, and there will be no detachment. The shape of the inner opening of the outer cover 5 is the same as that of the connecting cover 1, and the material of the outer cover 5 is the same as that of the control component 4.

[0029] The limiting post 8 is a cylindrical metal post, the length and diameter of which are consistent with the size of the opening of the connecting block 2. The surface of the limiting post 8 is smooth to ensure that the connecting block 2 can slide smoothly when it is inserted and removed, reducing frictional resistance. The limiting post 8 is fixed to the inner bottom wall of the connecting cover 1 by welding to ensure a stable connection. The shape and size of the connecting block 2 are adapted to the T-shaped space inside the connecting cover 1. The material of the connecting block 2 is the same as that of the connecting cover 1. The connecting block 2 is designed with a through hole that matches the limiting post 8, so that the connecting block 2 can be inserted into the limiting post 8. The connecting block 2 has a groove inside that matches the limiting part 3.

[0030] Reference Figure 6 and Figure 7 The adjustment assembly includes two clamping blocks 11. The left clamping block 11 is fixedly connected to the connecting cover 1. The right clamping block 11 has a control panel 15 on its right side. A threaded rod 14 is fixedly connected to the left side of the control panel 15. The threaded rod 14 is threadedly connected to the two clamping blocks 11.

[0031] Specifically, the left clamping block 11 and the connecting cover 1 are connected by welding to ensure a stable connection. The right clamping block 11 is set opposite to the left clamping block 11. The clamping block 11 is made of alloy steel to ensure that it has sufficient strength to clamp the gas pipeline body 16. The surface of the clamping block 11 that contacts the gas pipeline body 16 is provided with anti-slip texture to increase the friction with the pipeline and ensure that it can be firmly fixed to the pipeline after the device position is adjusted.

[0032] The two clamping blocks 11 are provided with sliding grooves that match the four sliding columns 12 and multiple control discs 15, so as to ensure that the sliding columns 12 and control discs 15 can slide smoothly in them, while restricting the degree of freedom of the clamping blocks 11 during the movement, so that they can only move in a straight line along the axial direction of the sliding columns 12 and control discs 15, thereby ensuring the accuracy and stability of the position adjustment.

[0033] Reference Figure 2 The connecting block 2 is in close contact with the inner wall of the connecting cover 1, and the detection device body 9 is fixedly connected to the left side of the connecting block 2.

[0034] Specifically, the shape of the connecting block 2 is precisely matched with the inner wall of the connecting cover 1, and the side of the connecting block 2 fits against the inner wall of the connecting cover 1.

[0035] Reference Figure 4 The limiting component 3 is a cuboid, and both sides of the limiting component 3 are curved surfaces.

[0036] Specifically, the limiting member 3 is rectangular in shape with curved surfaces on both sides, and the shape of the limiting member 3 rotating in one revolution is consistent with the groove opened inside the connecting block 2.

[0037] Reference Figure 5 The control component 4 is a cylinder, and the reset component 6 is a reset spring.

[0038] Specifically, the control component 4 is designed as a cylinder with a smooth surface to reduce friction. The cylinder's axis is clearly defined, which ensures the stability of the control component 4 during rotation. Whether rotating or being pushed or pulled, the cylinder can better disperse external forces, reduce stress concentration, and prevent the control component 4 from deforming or being damaged. The reset component 6 is a reset spring. When the control component 4 is subjected to external force and deviates from its initial position, the reset spring can use its elastic force to drive the control component 4 back to its initial position, thus realizing the automatic reset function.

[0039] Reference Figure 1 and Figure 7 A gas pipeline body 16 is provided between the two clamping blocks 11, and four sliding columns 12 are slidably connected inside the two clamping blocks 11.

[0040] Specifically, two clamping blocks 11 are symmetrically arranged on both sides of the gas pipeline body 16. Their design purpose is to clamp and position the gas pipeline body 16 by moving towards or away from each other, thereby firmly installing the entire gas leak detection device on the gas pipeline. The contact part between the clamping blocks 11 and the gas pipeline body 16 is designed according to the shape of the pipeline to achieve a better fit.

[0041] The dimensions of the sliding grooves inside the two clamping blocks 11 are matched with the diameter and length of the sliding column 12 to ensure that the sliding column 12 can slide smoothly in the sliding grooves, while also guiding the movement of the clamping blocks 11. The sliding column 12 is made of stainless steel, which has good wear resistance and corrosion resistance to adapt to complex underground environmental conditions.

[0042] Reference Figure 1 A sensor 10 is fixedly connected to the rear side of the detection device body 9, and a display panel 17 is provided on the left side of the detection device body 9.

[0043] Specifically, sensor 10 can detect the presence of gas in the surrounding environment and convert information such as gas concentration into electrical signals. The electrical signals converted by sensor 10 are transmitted to the processing circuit inside the detection device body 9 for processing, and the processed results are displayed through display panel 17.

[0044] Reference Figure 7 Each of the four sliding pillars 12 has a limit block 13 fixedly connected to both ends, and the multiple limit blocks 13 are slidably connected to the two clamping blocks 11.

[0045] Specifically, the limiting block 13 and the sliding column 12 are connected by welding, which can effectively withstand various stresses generated during the operation of the device.

[0046] Working principle: During installation, rotate the control component 4, which drives the limit component 3 to rotate to the horizontal. Then pull the control component 4 to move the limit component 3 into the inside of the connecting cover 1. At this time, the connecting block 2 is put into the two limit posts 8 fixed on the bottom wall of the inner wall of the connecting cover 1. The limit posts 8 play a preliminary positioning role, so that the connecting block 2 can be accurately placed in the predetermined position inside the connecting cover 1.

[0047] Finally, push the control component 4, which drives the limit component 3 to move into the connecting block 2. The reset component 6 drives the control component 4 to reset, and the control component 4 drives the limit component 3 to rotate and lock into the connecting block 2, thereby achieving basic positioning. Finally, rotate the bolt 7. As the bolt 7 is tightened, the connecting block 2 and the connecting cover 1 are tightly connected, thereby quickly installing the gas leak detection device and solving the problem of cumbersome and time-consuming installation of the gas leak detection device.

[0048] When it is necessary to adjust the position of the gas leak detection device on the gas pipeline body 16, rotate the control disk 15 to drive the threaded rod 14 to rotate. When the threaded rod 14 rotates, the right clamping block 11 will move away from the left clamping block 11 in a straight line along the axial direction of the threaded rod 14. At this time, move the whole device to the appropriate position. Finally, rotate the control disk 15 in the opposite direction to fix the whole device in the appropriate position, thus solving the problem that the gas leak detection device cannot detect gas leaks at different locations in the pipeline.

[0049] During the detection process, the sensor 10 fixedly connected to the rear of the detection device body 9 is responsible for detecting whether the gas is leaking and related parameters. The sensor 10 can sense the presence of gas in the surrounding environment and convert information such as gas concentration into electrical signals. The electrical signals converted by the sensor 10 are transmitted to the processing circuit inside the detection device body 9 for processing, and the processed results are displayed through the display panel 17.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
