Description

Technical Field

[0001] This utility model belongs to the field of gas concentration detection technology, and in particular relates to a wall-mounted methane detection device for mine detection. Background Technology

[0002] The wall-mounted methane detection device is designed specifically for mining environments. It features high-sensitivity detection, real-time audible and visual alarms, and a robust explosion-proof structure. It is easy to install, adaptable to complex working conditions, and can effectively warn of abnormal methane concentrations, ensuring safety in underground operations. It is durable and reliable, making it an ideal choice for mine gas monitoring.

[0003] While wall-mounted methane detectors currently on the market can detect methane, they lack protective measures. If a falling rock hits the detector, it will damage the device and require frequent replacements. This not only fails to save costs but also affects the work process, thus requiring improvement.

[0004] Based on this, this utility model designs a wall-mounted methane detection device for mine inspection to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that although wall-mounted methane detection devices can detect methane, they lack protective measures. If a falling rock hits the detection device, it will damage the device and require frequent replacement, which is neither cost-effective nor conducive to the work process. Therefore, this utility model proposes a wall-mounted methane detection device for mine detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wall-mounted methane detection device for mine inspection includes a main body. Multiple sliding grooves are symmetrically formed on one side of the main body. A sliding column is fixedly installed inside the sliding groove. A buffer spring is provided on the surface of the sliding column. Multiple limit grooves are symmetrically formed on the inner wall of the sliding groove. A sliding plate is provided inside the sliding groove. A sliding hole is formed inside the sliding plate, and the position of the sliding hole corresponds to the position of the sliding column. Limit blocks are fixedly installed on both sides of the sliding plate, and the positions of the limit blocks correspond to the positions of the limit grooves.

[0008] As a further description of the above technical solution:

[0009] A transparent protective plate is fixedly installed at one end of each of the sliding plates. The top of the transparent protective plate has multiple support holes. The top of the main body has multiple support columns fixedly installed, and the positions of the support columns correspond to the positions of the support holes.

[0010] As a further description of the above technical solution:

[0011] The surface of the support column is provided with a support spring, the top of the support column is fixedly installed with an installation cap, and the top of the main body is fixedly installed with an elastic block in the middle of the multiple support columns.

[0012] As a further description of the above technical solution:

[0013] Multiple mounting blocks are fixedly installed on both sides of the main body, and screw holes are opened inside the mounting blocks.

[0014] As a further description of the above technical solution:

[0015] The main body has an installation groove inside, and a detection unit is provided inside the main body through the bottom of the installation groove. A filter ring is provided on the top of the detection unit.

[0016] As a further description of the above technical solution:

[0017] Multiple audible and visual alarms are symmetrically fixedly installed at the bottom of the main body, and a display screen is provided on one side of the main body.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting a buffer spring and a sliding plate, the wall-mounted methane detection device is used in mines. Due to the complex environment and internal structure of mines, falling rocks are very likely to occur. If a falling rock falls on the top of the main body, the impact of the falling rock will cause the transparent protective plate to move downward. The transparent protective plate will also drive multiple sliding plates on one side to move downward inside the sliding groove. The sliding plates will drive the internal sliding holes to slide on the surface of the sliding column and squeeze the buffer spring. After the impact disappears, the buffer spring will reset and lift up multiple sliding plates, causing the transparent protective plate to reset, so as to buffer the impact of the falling rock, reduce damage to the main body, and prevent the falling rock from directly impacting the main body.

[0020] 2. In this utility model, by setting a support column and a support spring, when the transparent protective plate is impacted, the impact causes the transparent protective plate to move downward. The transparent protective plate drives the support hole at the top to slide against the surface of the support column and compresses the support spring to deform. When one side of the transparent protective plate touches the top of the elastic block, the support spring resets and drives the transparent protective plate back to its original position, so as to absorb the damage to the main body caused by the impact.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see the appendix Figure 1 -Appendix Figure 3 This utility model provides a technical solution: a wall-mounted methane detection device for mine detection, comprising a main body 1, with multiple symmetrical sliding grooves 2 on one side of the main body 1, a sliding column 3 fixedly installed inside the sliding groove 2, a buffer spring 4 provided on the surface of the sliding column 3, multiple symmetrical limiting grooves 5 on the inner wall of the sliding groove 2, a sliding plate 6 inside the sliding groove 2, a sliding hole 7 inside the sliding plate 6, the position of the sliding hole 7 corresponding to the position of the sliding column 3, and limiting blocks 8 fixedly installed on both sides of the sliding plate 6, the position of the limiting blocks 8 corresponding to the position of the limiting grooves 5.

[0028] The specific implementation method is as follows: a transparent protective plate 9 is fixedly installed at one end of a plurality of sliding plates 6, and a plurality of support holes 10 are provided on the top of the transparent protective plate 9. A plurality of support columns 11 are fixedly installed on the top of the main body 1, and the positions of the support columns 11 correspond to the positions of the support holes 10.

[0029] By setting support holes 10 and support columns 11, when the transparent protective plate 9 is impacted, the transparent protective plate 9 causes the support holes 10 to slide against the surface of the support columns 11, and the support spring 12 on the surface of the support columns 11 is deformed to absorb the impact and play a buffering role.

[0030] The specific implementation method is as follows: a support spring 12 is provided on the surface of the support column 11, an installation cap 13 is fixedly installed on the top of the support column 11, and an elastic block 14 is fixedly installed on the top of the main body 1 in the middle of the multiple support columns 11.

[0031] By setting a support spring 12 and an elastic block 14, when the transparent protective plate 9 is impacted, the transparent protective plate 9 causes the support hole 10 to slide against the surface of the support column 11, and the support spring 12 is deformed by squeezing. At the same time, when the transparent protective plate 9 touches the elastic block 14 on one side, the support spring 12 resets and causes the transparent protective plate 9 to move upward, so as to ensure that the transparent protective plate 9 can provide protection on the top of the main body 1.

[0032] The specific implementation method is as follows: multiple mounting blocks 15 are fixedly installed on both sides of the main body 1, and screw holes 16 are opened inside the mounting blocks 15.

[0033] By setting up mounting blocks 15 and screw holes 16, this methane detection device is used in mines. In mines, it is a wall-mounted installation method. The main body 1 is placed in a designated position close to the wall. After multiple mounting blocks 15 are attached to the wall, holes are drilled. Then, expansion screws are installed inside the mounting blocks 15 through the screw holes 16 to fix the main body 1.

[0034] The specific implementation method is as follows: the main body 1 has an installation groove 17 inside, the bottom of the main body 1 through the installation groove 17 is provided with a detection unit 18, and the top of the detection unit 18 is provided with a filter ring 19.

[0035] By setting up a detection unit 18 and a filter ring 19, this methane detection device is used inside a mine, where there is a lot of dust. The filter ring 19 at the bottom of the detection unit 18 isolates the dust and does not affect its detection capability. The filter ring 19 is replaced regularly to ensure that the detection unit 18 is not affected by dust.

[0036] The specific implementation method is as follows: multiple audible and visual alarms 20 are symmetrically fixedly installed at the bottom of the main body 1, and a display screen 21 is provided on one side of the main body 1.

[0037] By setting up an audible and visual alarm 20 and a display screen 21, when the methane detection device is working, the data can still be clearly read under strong light through the display screen 21 set on one side of the main body 1, and the environmental parameters can be displayed in real time to reduce misjudgment. If the methane density is too high, the audible and visual alarm 20 will start and sound an alarm. The graded response of the audible and visual alarm 20 improves emergency efficiency, the directional sound wave penetrates the noise, and the light signal compensates for the sound blind spot.

[0038] Working principle and usage: This methane detection device is used inside a mine, therefore it adopts a wall-mounted installation method. The main body 1 is placed in a designated position, and multiple mounting blocks 15 are drilled close to the wall. By aligning the expansion screws with the screw holes 16, the filter ring 19 at the bottom of the detection unit 18 can block most of the dust inside the mine, preventing surface dust from affecting the monitoring capability of the detection unit 18. If a rock falls into the mine and hits the top of the main body 1, the impact of the rock will cause the transparent protective plate 9 to move downward inside the sliding groove 2, and the transparent protective plate 9 will cause the internal sliding hole 7 to move in the sliding column 3. The surface friction slides and compresses the buffer spring 4 to deform, so as to buffer the impact force of falling rocks. After the transparent protective plate 9 touches the elastic block 14 on the top of the main body 1, multiple buffer springs 4 reset and drive the transparent protective plate 9 to move upward, so as to ensure that the transparent protective plate 9 returns to the top of the main body 1 for protection, so as to prevent falling rocks from directly hitting the main body 1. The methane content inside the mine can be observed through the sound and light alarm 20. If the methane content is too high, the density is too large, and exceeds the set data, the sound and light alarm 20 at the bottom of the main body 1 will sound an alarm to indicate that the personnel inside the mine are in danger.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
