Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A downhole gas monitoring device comprises a placement box 1, wherein a storage chamber 11 is provided inside the placement box 1, a spacing groove 12 is provided inside the placement box 1 at the front end of the storage chamber 11, a dustproof net 13 is fixedly installed at the middle of the front end of the placement box 1, a gas monitoring device 7 is placed inside the storage chamber 11, a column 4 is fixedly installed at the top rear end of the placement box 1, a protective component 5 is arranged on the top of the column 4, the protective component 5 comprises a mounting plate 51, the mounting plate 51 is movably mounted on the top of the column 4, spring plates 53 are movably mounted on the left and right sides of the top of the mounting plate 51, a spring 54 is fixedly installed between the spring plate 53 and the mounting plate 51, a first hinge 52 is movably installed at the connection between the spring plate 53 and the mounting plate 51, the A stop block 55 is fixedly installed at the rear end of the bottom of the mounting plate 51 at the connection between the mounting plate 51 and the column 4, a display screen 71 is fixedly installed at the top of the front end of the gas monitoring device 7, buzzers 72 are fixedly installed on both sides of the display screen 71 at the front end of the gas monitoring device 7, a control button 73 is fixedly installed at the front end of the gas monitoring device 7 below the display screen 71, a monitoring window 74 is fixedly installed at the front end of the gas monitoring device 7 below the control button 73, two groups of spring plates 53 installed on the top of the protective component 5 are convex and inclined to the left and right sides, a second hinge 6 is movably installed at the connection between the mounting plate 51 and the column 4, a fixing ring 3 is fixedly installed at the rear end of the placement box 1, and a rubber gasket 31 is fixedly installed on the inner wall of the fixing ring 3.

[0029] By adopting the above technical solution, when in use, the placement box 1 is fixed by the fixing ring 3 at the rear end thereof. A rubber gasket 31 is arranged inside the fixing ring 3 so that the applicable scope of the fixing ring 3 is improved, and the problem that the fixing ring 3 cannot be installed normally due to the small diameter or irregular shape of the tubular object fixed by the fixing ring 3 when the device is fixed is avoided. After the placement box 1 is fixed, the mounting plate 51 on the top of the column 4 is flipped upward to facilitate the placement of the gas monitoring device 7, the gas monitoring device 7 is inserted into the storage chamber 11, and then the mounting plate 51 is flipped back to cover the top of the gas monitoring device 7. The two sets of spring plates 53 installed on the top of the protective component 5 are inclined to the left and right sides in a convex shape, and are fixed by the column 4. The support, when the falling rocks fall on the spring plate 53 above the installation plate 51, the falling rocks will not accumulate on the top of the spring plate 53, and the broken rocks will hit the spring plate 53. The spring plate 53 is forced to compress the spring 54 downward, and the spring 54 is compressed and reset to make the spring plate 53 bounce up and bounce the broken rocks away, thereby protecting the gas monitoring device 7, preventing the problem of falling rocks hitting the gas monitoring device 7, and avoiding the accumulation of broken rocks on the top of the device. The gas monitoring device 7 can be directly inserted into the storage chamber 11 during installation, and no other operation is required. When taking it out, if the installation plate 51 is blocked, the installation plate 51 can be flipped upwards and then the gas monitoring device 7 can be taken out, thereby achieving the purpose of facilitating the installation and taking of the gas monitoring device 7.

[0030] Specifically, Figures 1 to 4 As shown, the front end of the placement box 1 is located on the left and right sides of the dustproof net 13 and is provided with sliding grooves 14. The front end of the placement box 1 is provided with a cleaning component 2 through the sliding grooves 14. The cleaning component 2 includes a first transverse plate 21, which is movably mounted on the front end surface of the placement box 1. The left and right sides of the rear end of the first transverse plate 21 are fixedly mounted with connecting plates 22. The rear end of the first transverse plate 21 is located between the two groups of connecting plates 22 and is fixedly mounted with a first brush 23. The rear ends of the two groups of connecting plates 22 are fixedly mounted with a second transverse plate 24. The second transverse plate 2 4 is fixedly mounted with second bristles 25 on the front and rear end surfaces, the length of the first transverse plate 21 is longer than the length of the placement box 1, the second transverse plate 24 is located inside the spacing groove 12, the first bristles 23 at the rear end of the first transverse plate 21 and the second bristles 25 at the front end of the second transverse plate 24 are both in contact with the dustproof net 13, the second bristles 25 at the rear end of the second transverse plate 24 are in contact with the monitoring window 74 at the front end of the gas monitoring device 7 after installation, and two groups of dust exhaust ports 15 are provided at the bottom of the placement box 1, and the two groups of dust exhaust ports 15 are respectively communicated with the storage chamber 11 and the spacing groove 12.

[0031] By adopting the above technical solution, the environment in the general mine is poor. After the gas monitoring device 7 is used for a long time, dust may accumulate on the surface of the monitoring window 74, which may affect the operation of the monitoring components in the gas monitoring device 7. However, the existing monitoring equipment lacks means to solve this problem. The device is provided with a cleaning component 2 at the front end of the placement box 1. The cleaning component 2 is used to solve this problem. The length of the first cross plate 21 is longer than the length of the placement box 1. Therefore, the two ends of the first cross plate 21 extend out of the left and right sides of the placement box 1. When cleaning, the staff can pinch the two ends of the first cross plate 21 with their hands and slide the first cross plate 21 up and down. When the first cross plate 21 slides up and down in the sliding groove 14, the first cross plate 21 passes through the connecting plate 2 2 drives the second transverse plate 24 to move in the spacing groove 12. When the first transverse plate 21 moves, the first brush 23 installed on the rear end surface thereof cleans the front side of the dustproof net 13. When the second transverse plate 24 moves, the second brush 25 installed on the front end surface thereof cleans the back side of the dustproof net 13. At the same time, the second brush 25 installed on the rear end surface of the second transverse plate 24 cleans the monitoring window 74. The cleaned dust falls through the dust discharge port 15 opened at the bottom of the placement box 1 to prevent dust from accumulating in the storage chamber 11 and the spacing groove 12. Therefore, through the above structural design, the device is convenient for cleaning the dust accumulated on the surface of the dustproof net 13 and the monitoring window 74 to prevent the reduction of air intake due to dust blockage and affect the gas monitoring.

[0032] Working principle: When in use, the placement box 1 is installed through the fixing ring 3. After installation, the mounting plate 51 is flipped upward through the second hinge 6, and then the gas monitoring device 7 is inserted into the storage chamber 11. After the storage chamber 11 is placed, the mounting plate 51 is flipped back so that the mounting plate 51 covers the top of the gas monitoring device 7 to protect the gas monitoring device 7 and prevent the gas monitoring device 7 from being hit by falling rocks in the mine. Pinch the two ends of the first horizontal plate 21 and slide the first horizontal plate 21 up and down. During the sliding process, the first horizontal plate 21 drives the second horizontal plate 24 through the connecting plate 22. The first brush 23 and the second brush 25 clean the surface of the dustproof net 13 and the monitoring window 74, and the cleaned dust falls through the dust exhaust port 15 to prevent dust accumulation in the storage chamber 11 and the partition groove 12. When the gas monitoring device 7 is taken out from the storage chamber 11, the mounting plate 51 is turned over first and then the gas monitoring device 7 is taken out. After the mounting plate 51 is turned over, it is convenient to take out the gas monitoring device 7. The gas monitoring device 7 monitors the gas in the environment when working. If the gas content exceeds the preset value, an alarm is issued through the buzzer 72, and the display screen 71 can display the gas content value in real time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
