Description

Technical Field

[0001] This utility model relates to the technical field of gas leak detection devices, and more specifically to a gas leak detection device for buried urban gas pipelines. Background Technology

[0002] Gas leaks are caused by the accidental leakage of gas from pipelines or cylinders into the air. In urban areas, gas pipelines are usually buried underground. When a gas leak occurs, inspectors need to use a gas leak detector to detect the leak point. During the detection process, it is only necessary to drill a hole in the ground and then insert the detection probe of the gas leak detector into the hole to perform the detection.

[0003] Currently, gas leak detectors are usually connected to the detection probe via wires. However, the wires and detection probes are often exposed to the outside environment without any protective measures. In particular, the detection probes are exposed to the outside environment for a long time and are easily affected by dust or polluting gases. These substances can adhere to the sensitive elements of the probes, damaging their performance and causing errors in the measurement results. This needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas leak detection device for buried gas pipelines in urban areas, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a gas leak detection device for buried urban gas pipelines, comprising a gas leak detector. A display screen and control buttons are installed on the top of the front of the gas leak detector. A wire is fixedly installed in the middle of the top of the gas leak detector, and a detection probe is fixedly installed at one end of the wire. A protective mechanism is provided on the top of the gas leak detector, including a protective cover. The bottom of the protective cover is fixedly connected to the top of the gas leak detector. A protective cap is threaded onto the upper part of the outer wall of the protective cover. The wire is disposed inside the protective cover and the protective cap. A support plate is fixedly connected to the upper part of the inner side of the protective cover. A limit cover is fixedly connected to the top of the support plate. The outer wall of the detection probe is disposed inside the limit cover. A second arc-shaped clamp is provided on the left side inside the limit cover, and a first arc-shaped clamp is fixedly connected to the right side inside the limit cover. The two sides of the detection probe are disposed between the second arc-shaped clamp and the first arc-shaped clamp.

[0006] Furthermore, a mounting cover is fixedly connected to the left side of the limiting cover, and a lead screw is provided inside the mounting cover. The left end of the lead screw extends to the left side of the mounting cover and is fixedly connected to a knob, while the right end of the lead screw is rotatably connected to the left side of the limiting cover.

[0007] Furthermore, a push plate is slidably connected inside the mounting cover. The middle part of the push plate is threaded onto the outer wall of the lead screw. Two connecting rods are fixedly connected to the right side of the push plate. The outer wall of the connecting rod is movably sleeved on the left side of the limiting cover. One end of the connecting rod extends into the interior of the limiting cover and is fixedly connected to the left side of the second arc-shaped clamp.

[0008] Furthermore, the inner walls of both the No. 1 and No. 2 arc-shaped clamps are fixedly connected with rubber anti-slip pads, and the inner walls of the rubber anti-slip pads overlap the outer walls of the detection probe.

[0009] Furthermore, an anti-slip leather sleeve is fixedly fitted to the lower part of the outer wall of the gas leak detector, and a portable rope is fixedly connected to the bottom of the gas leak detector.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The gas leak detection device for buried urban gas pipelines involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1:

[0020] like Figure 1-4 As shown, a gas leak detection device for buried urban gas pipelines includes a gas leak detector 1. A display screen 2 and control buttons are mounted on the top of the front of the gas leak detector 1. A wire 4 is fixedly installed in the middle of the top of the gas leak detector 1, and a detection probe 5 is fixedly installed at one end of the wire 4. A protective mechanism 3 is provided on the top of the gas leak detector 1, including a protective cover 31. The bottom of the protective cover 31 is fixedly connected to the top of the gas leak detector 1. A protective cover 32 is threaded onto the upper part of the outer wall of the protective cover 31. The wire 4 is disposed inside the protective cover 31 and the protective cover 32. A support plate 33 is fixedly connected to the upper part of the inside of the protective cover 31. A limit cover 34 is fixedly connected to the top of the support plate 33. The outer wall of the detection probe 5 is disposed inside the limit cover 34. A detection probe 5 is disposed on the left side inside the limit cover 34. The second arc-shaped clamp 392 is fixedly connected to the right side of the inner side of the limiting cover 34, and the first arc-shaped clamp 35 is fixedly connected to the second arc-shaped clamp 392 and the first arc-shaped clamp 35. The two sides of the detection probe 5 are set between the second arc-shaped clamp 392 and the first arc-shaped clamp 35. The left side of the limiting cover 34 is fixedly connected to the mounting cover 34, and the mounting cover 36 is equipped with a lead screw 38. The left end of the lead screw 38 extends to the left side of the mounting cover 36 and is fixedly connected to a knob 37. The right end of the lead screw 38 is rotatably connected to the left side of the limiting cover 34. The mounting cover 36 is slidably connected to a push plate 39. The middle part of the push plate 39 is threaded onto the outer wall of the lead screw 38. The right side of the push plate 39 is fixedly connected to two connecting rods 391. The outer wall of the connecting rods 391 is movably sleeved on the left side of the limiting cover 34. One end of the connecting rod 391 extends into the inner side of the limiting cover 34 and is fixedly connected to the left side of the second arc-shaped clamp 392.

[0021] In this embodiment, the limiting cover 34 facilitates the placement of the detection probe 5. By rotating the knob 37 and the lead screw 38, the push plate 39, the connecting rod 391, and the second arc-shaped clamping plate 392 can be moved, thereby facilitating the clamping and fixing of the detection probe 5 between the second arc-shaped clamping plate 392 and the first arc-shaped clamping plate 35 inside the limiting cover 34. By threading the protective cover 32 and the protective cover 31 together, the wire 4 and the detection probe 5 can be stored and protected inside the protective cover 32 and the protective cover 31.

[0022] Example 2:

[0023] like Figure 1-4 As shown, rubber anti-slip pads 393 are fixedly connected to the inner walls of the first arc-shaped clamp 35 and the second arc-shaped clamp 392. The inner wall of the rubber anti-slip pads 393 overlaps the outer wall of the detection probe 5. An anti-slip leather sleeve 6 is fixedly fitted to the lower part of the outer wall of the gas leak detector 1. A portable rope 7 is fixedly connected to the bottom of the gas leak detector 1.

[0024] In this embodiment, the rubber anti-slip pad 393 increases the anti-slip properties of the first arc-shaped clamp 35 and the second arc-shaped clamp 392 when clamping and fixing the detection probe 5. The anti-slip leather sleeve 6 increases the anti-slip properties when the staff holds the gas leak detector 1. The portable rope 7 makes it convenient for the staff to carry the gas leak detector 1.

[0025] In summary, as Figure 1-4 As shown, this type of gas leak detection device for buried urban gas pipelines is used by first unscrewing the protective cover 32 and then rotating the knob 37. The knob 37 drives the lead screw 38 to rotate, which in turn drives the push plate 39 and connecting rod 391 to move. This causes one end of the connecting rod 391 to disengage the second arc-shaped clamp 392 and the rubber anti-slip pad 393 from one side of the detection probe 5. At this point, the detection probe 5 can be removed from inside the limiting cover 34. By moving the detection probe 5, the wire 4 can be removed from inside the protective cover 31. Then, a hole is drilled in the ground at the leak point, and then... The gas leak detector 1 inserts its detection probe 5 into the hole for detection. After detection, the wire 4 is retracted into the protective cover 31, and the detection probe 5 is placed inside the limiting cover 34. At this time, the knob 37 and the lead screw 38 are rotated in the opposite direction, and the second arc-shaped clamp 392 is driven to move in the opposite direction in the same way. The detection probe 5 is clamped and fixed between the second arc-shaped clamp 392 and the first arc-shaped clamp 35 inside the limiting cover 34. Then, the lower thread inside the protective cover 32 is connected to the inside of the protective cover 31 to protect the wire 4 and the detection probe 5.
