[0002] With social development and the improvement of people's living standards, gas has gradually become an indispensable part of people's daily life and work. However, since gas pipeline leaks often occur at gas pipeline valves, gas valves, as areas with high leakage and easy accumulation, are necessary for monitoring.

[0003] Currently, the common method for monitoring leaks in natural gas pipeline valves is to conduct manual inspections using handheld gas monitors. However, these methods have limitations: manual inspections are inefficient and prone to errors, and some gases are toxic, so close-range manual monitoring can easily cause irreversible harm to human health. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A gas valve leakage monitoring device, comprising:

[0006] A first housing, with a gas alarm connected inside the first housing, and a pair of side plates connected to the front side of the first housing near the outer side of the gas alarm;

[0007] A pair of back plates are connected to the upper and lower back sides of the first outer shell. A second outer shell is slidably connected to the outer side of the back plates. A pair of second through holes are opened on the back side of the second outer shell. A U-shaped plate is inserted into the inside of the pair of second through holes. A slot is opened on both sides of the U-shaped plate near the end.

[0008] A limit mechanism is provided inside the second housing near the second through hole.

[0009] In one possible implementation, the limiting mechanism includes a partition connected to the inner wall of the second housing, with a pair of return springs connected to both sides of the partition, one end of each pair of return springs connected to a movable plate, one side of which extends into the interior of the slot.

[0010] In one possible implementation, a pair of grooves are provided on the other side of the movable plate, and one end of the return spring extends into the interior of the grooves.

[0011] In one possible implementation, a second sliding groove is provided on the back side of the movable plate, and a second slider is slidably connected inside the second sliding groove. One side of the second slider is fixedly connected to the inner wall of the second outer shell.

[0012] In one possible implementation, a pair of first through holes are provided on both the upper and lower sides of the second housing, and a connecting plate is slidably connected inside the first through hole. One side of the connecting plate is fixedly connected to the movable plate.

[0013] In one possible implementation, both sides of the U-shaped plate are chamfered.

[0014] In one possible implementation, a pair of first grooves are provided on the front side of the second housing, and a first slider is slidably connected inside the first groove, with one side of the first slider being fixedly connected to the back plate.

[0015] In one possible implementation, the first slider is set to an arc shape.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] By fitting a U-shaped plate over the gas pipeline and inserting both ends of the U-shaped plate into the second outer casing, the movable plate is driven into the slot on the inner wall of the U-shaped plate by the elastic action of the return spring, thus completing the installation and fixing of the gas alarm. When a leak occurs in the pipeline, the gas alarm will remind relevant personnel to take emergency measures, achieving the effect of real-time monitoring. The monitoring efficiency is high, eliminating the need for manual handheld gas monitors for inspection and monitoring, and avoiding situations that may cause harm to the human body.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This application provides a gas valve leakage monitoring device to solve the problems in the prior art.

[0029] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example 1

[0030] The specific structure of this embodiment is as follows: Figures 1-6 As shown, a gas valve leakage monitoring device includes:

[0031] The first housing 3 has a gas alarm 1 connected inside it. A pair of side plates 2 are connected to the front side of the first housing 3 near the outer side of the gas alarm 1. By setting the gas alarm 1, when a leak occurs in the pipeline, the detector will respond quickly and issue an alarm signal to remind relevant personnel to take emergency measures and eliminate potential hazards in time.

[0032] A pair of back plates 9 are connected to the upper and lower back sides of the first outer shell 3. The second outer shell 6 is slidably connected to the outer side of the back plate 9. A pair of second through holes 15 are opened on the back side of the second outer shell 6. A U-shaped plate 7 is inserted into the inside of the pair of second through holes 15. A slot 17 is opened on both sides of the U-shaped plate 7 near the end.

[0033] A limit mechanism is provided inside the second outer casing 6 near the second through hole 15.

[0034] In some examples, the limiting mechanism includes a partition 11 connected to the inner wall of the second housing 6. A pair of return springs 12 are connected to both sides of the partition 11. One end of the pair of return springs 12 is connected to a movable plate 14. One side of the movable plate 14 extends into the interior of the slot 17. Under the elastic action of the return springs 12, the movable plate 14 is driven to insert into the slot 17 on the inner wall of the U-shaped plate 7, thus fixing the U-shaped plate 7. Conversely, when the pair of movable plates 14 move towards each other, they squeeze the return springs 12, causing one side of the movable plate 14 to be removed from the interior of the slot 17, making it easier to remove the U-shaped plate 7.

[0035] In some examples, a pair of grooves 18 are provided on the other side of the movable plate 14, and one end of the return spring 12 extends into the interior of the groove 18 so that the return spring 12 can retract into the interior of the groove 18 when the pair of connecting plates 4 move toward each other.

[0036] In some examples, a second slide groove 13 is provided on the back side of the movable plate 14, and a second slider 16 is slidably connected inside the second slide groove 13. One side of the second slider 16 is fixedly connected to the inner wall of the second outer shell 6. Under the connection of the second slide groove 13 and the second slider 16, the stability of the movable plate 14 during left and right movement is improved.

[0037] In some examples, a pair of first through holes 5 are provided on the upper and lower sides of the second outer shell 6. A connecting plate 4 is slidably connected inside the first through hole 5. One side of the connecting plate 4 is fixedly connected to the movable plate 14. When it is necessary to remove the two sides of the U-shaped plate 7 from the inside of the second through hole 15, simply hold the pair of connecting plates 4 on the upper and lower sides with both hands, so that the pair of connecting plates 4 move towards each other, thereby driving the movable plate 14 connected to the pair of connecting plates 4 to move towards each other, so that one side of the movable plate 14 is removed from the inside of the slot 17.

[0038] In some examples, both sides of the U-shaped plate 7 are chamfered to facilitate the insertion of both sides of the U-shaped plate 7 into the second through hole 15.

[0039] In some examples, a pair of first slide grooves 10 are provided on the front side of the second housing 6. A first slider 8 is slidably connected inside the first slide groove 10. One side of the first slider 8 is fixedly connected to the back plate 9. Under the connection of the first slide groove 10 and the first slider 8, it is convenient to rotate the inside of the first housing 3 and the gas alarm 1 inside it, and to make it convenient for the gas alarm 1 to rotate along the front side of the second housing 6, so as to facilitate multi-angle adjustment.

[0040] In some examples, the first slider 8 is set to an arc shape to facilitate the sliding of the first slider 8 along the inside of the first groove 10.

[0041] This utility model involves fitting a U-shaped plate 7 onto a gas pipeline and inserting both ends of the U-shaped plate 7 into the second outer casing 6. Under the elastic action of the return spring 12, the movable plate 14 is driven to insert into the slot 17 on the inner wall of the U-shaped plate 7, thus completing the installation and fixation of the gas alarm 1. When a leak occurs in the pipeline, the gas alarm 1 will remind relevant personnel to take emergency measures, achieving the effect of real-time monitoring. The monitoring efficiency is high, eliminating the need for manual handheld gas monitors for inspection and monitoring, and avoiding situations that may cause harm to the human body.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
