Description

Technical Field

[0001] This utility model relates to the technical field of gas pipeline monitoring equipment, and in particular to an energized alarm for metal external climbing pipes. Background Technology

[0002] With the rapid increase in the number of gas pipeline metal external pipes, especially in rural areas, the risks associated with these pipes need further attention. One common risk is electrified external pipes. Due to the lower level of urban planning in rural areas, some electrical circuits and wires are laid along these pipes. During extreme weather conditions such as strong winds and heavy rains, these wires can easily come into contact with the pipes, causing them to become electrified. Furthermore, the lack of steel-plastic conversion devices at the point of entry for metal external pipes connecting to indoor gas pipelines can also lead to electrified external pipes if electrical connections are improper in rural households. Electrified external pipes not only cause serious injury to those who come into contact with them but also corrode the pipelines, leading to leaks and other accidents. Currently, there is no technology to detect whether gas pipeline external pipes are electrified; therefore, this application proposes an electrified alarm for metal external pipes. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a live-line alarm for metal external climbing pipes with live detection.

[0004] The technical solution of this utility model is as follows: a live alarm for a metal external climbing pipe, including a metal external climbing pipe, an audible and visual alarm installed on the metal external climbing pipe, an electromagnetic relay electrically connected to the audible and visual alarm, and a clamping installation component connecting the electromagnetic relay, the audible and visual alarm and the metal external climbing pipe.

[0005] The clamping mounting component includes an assembly block and a clamping block disposed at both ends. A pressing block is fixedly connected to one side of the clamping block. An adjustment cavity is provided inside the assembly block. An elastic block is disposed inside the adjustment cavity. A guide rod is also connected to the inner wall of the adjustment cavity. A lifting rod is slidably mounted on the guide rod. A limit block is fixedly connected to one side of the lifting rod.

[0006] Optionally, the electromagnetic relay is also connected to a grounding device, and the grounding device, the electromagnetic relay, the metal external creep pipe, and the audible and visual alarm form a circuit.

[0007] Optionally, limiting holes are provided on both sides of the pressing block, and the two sets of limiting blocks are respectively engaged in the corresponding limiting holes.

[0008] Optionally, a U-shaped groove is provided on one side of the assembly block, and a sliding hole penetrating the adjustment cavity is provided on the inner wall of the U-shaped groove. The limiting block is installed through the sliding hole and the limiting hole respectively.

[0009] Optionally, the lifting rod has a through hole, and the guide rod passes through the through hole and is fixedly connected to the inner wall of the adjustment cavity.

[0010] Optionally, a second spring is connected to one side of the through hole, and the other end of the second spring is connected to the inner wall of the adjustment cavity. The second spring is sleeved on the outer ring of the guide rod.

[0033] Example 1

[0034] like Figure 5 As shown, the present invention proposes a live metal external pipe alarm, including a metal external pipe 1, an audible and visual alarm 3 installed on the metal external pipe 1, an electromagnetic relay 2 electrically connected to the audible and visual alarm 3, a clamping mounting part 4 connecting the electromagnetic relay 2, the audible and visual alarm 3 and the metal external pipe 1, and the electromagnetic relay 2 is also connected to a grounding device, forming a circuit with the grounding device, the electromagnetic relay 2, the metal external pipe 1 and the audible and visual alarm 3.

[0035] In this embodiment, the clamping mounting part 4 is used to install the audible and visual alarm 3 and the electromagnetic relay 2 corresponding to the metal external climbing pipe 1. The audible and visual alarm 3 and the electromagnetic relay 2 are connected to the grounding device by a metal wire to form a connection loop from the metal external climbing pipe 1 to the ground.

[0036] The audible and visual alarm 3 consists of two parts: an electromagnetic relay 2 and an audible and visual alarm 3. When current flows through the electromagnetic relay 2, the electromagnetic relay 2 is in a closed state, which closes the circuit and triggers the alarm.

[0037] Example 2

[0038] like Figure 1-4 As shown, based on Embodiment 1, the clamping mounting component 4 includes an assembly block 41 and a clamping block 42 disposed at both ends thereon. A U-shaped groove is provided on one side of the assembly block 41, and a sliding hole penetrating the adjustment cavity 410 is provided on the inner wall of the U-shaped groove.

[0039] like Figure 3 and Figure 4 As shown, a pressing block 43 is fixedly connected to one side of the mounting block 42. Limiting holes are opened on both sides of the pressing block 43. The limiting block 416 is installed through the sliding hole and corresponds to the limiting hole. An adjustment cavity 410 is opened in the assembly block 41. An elastic block 412 is provided in the adjustment cavity 410. The elastic block 412 is slidably disposed with the inner wall of the adjustment cavity 410. Two sets of first springs 411 are fixedly connected to one side of the elastic block 412. The other end of the first spring 411 is fixedly connected to the inner wall of the adjustment cavity 410.

[0040] A guide rod 414 is also connected to the inner wall of the adjustment cavity 410. A lifting rod 415 is slidably mounted on the guide rod 414. A through hole is provided on the lifting rod 415. The guide rod 414 passes through the through hole and is fixedly connected to the inner wall of the adjustment cavity 410. A second spring 417 is connected to one side of the through hole. The other end of the second spring 417 is connected to the inner wall of the adjustment cavity 410. The second spring 417 is sleeved on the outer ring of the guide rod 414. A limit block is fixedly connected to one side of the lifting rod 415. 416, connecting rods 413 are fixedly connected to both sides of elastic block 412, and an arc-shaped guide groove is opened at the end of lifting rod 415 away from limit block 416. An arc-shaped guide block is connected to one end of connecting rod 413. The arc-shaped guide block is adapted to slide with the inner wall of the arc-shaped guide groove. Two sets of limit blocks 416 are respectively locked in the two limit holes. A lifting groove hole 418 penetrating assembly block 41 is opened on one side of adjustment cavity 410, and a moving block 419 is fixedly connected to one side of guide rod 414.

[0041] In this embodiment, the pressing block 43 is pressed against the elastic block 412, causing the elastic block 412 to enter the adjustment cavity 410. The inward push of the elastic block 412 compresses the first spring 411. At the same time, the connecting rod 413 slides along the arc-shaped guide groove to one side of the lifting rod 415. The lifting rod 415 disengages from the contact of the connecting rod 413 and, under the rebound action of the second spring 417, slides along the guide rod 414, causing the lifting rod 415 to push the limiting block 416 out of the adjustment cavity 410, thereby realizing the locking of the limiting block 416 against the upper limit hole of the pressing block 43, thus realizing the installation of the clamping mounting part 4. The audible and visual alarm 3 and the electromagnetic relay 2 monitor the metal external crawling pipe 1.

[0042] When opening, disassembling and replacing the clamping mounting part 4, slide the moving block 419 along the lifting slot hole 418, so that the lifting rod 415 retracts into the adjusting cavity 410 under the pushing action of the lifting slot hole 418, thereby the limiting block 416 disengages from the limiting hole on the pressing block 43, and the pressing block 43 is pulled to disengage from the U-shaped groove of the assembly block 41.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
