Description

Technical Field

[0001] The utility model relates to the technical field of mining monitoring devices, in particular to a mining real-time monitoring device. Background Art

[0002] A mining area refers to a coalfield or part of it that is uniformly planned and developed, including an area with several mines or open-pit mines, with complete production processes, ground transportation, power supply, communication scheduling, production management, and life service facilities. Its scope often depends on the scale of the ore deposit. The real-time monitoring device for mining is a device used to monitor the air quality in mining areas.

[0003] The utility model patent with announcement number CN218674427U discloses a real-time monitoring device for mining, which belongs to the field of mining devices. The real-time monitoring device for mining includes a device body, the right end of the device body is fixedly connected to a side bottom pile, the right end of the side bottom pile is fixedly connected to a corrugated hose, the front side of the right end of the side bottom pile is rotatably connected to a spherical block, the right end of the spherical block is fixedly connected to an electric push rod, the output end of the electric push rod is fixedly connected to an annular hoop, the annular hoop is connected to the right end of the corrugated hose, the inner end of the device body is fixedly connected to a detection mechanism, the detection mechanism includes a detection inner cavity, a gas sensor is installed in the detection inner cavity, and a suction pump is fixedly connected in the detection inner cavity. In the process of collecting sample gas through the corrugated hose, the scheme can drive the annular hoop at the rightmost end of the corrugated hose to move right through the electric push rod, and stretch the corrugated hose to extend to the side range of the device body. This method can make the gas collection range of the device body wider.

[0004] However, the above patent still has shortcomings: this patent uses a suction pump and a corrugated hose to suck the gas in the mine into the inner cavity, and the gas sensor detects whether it is abnormal.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

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.

[0026] See also Figures 1 to 6 The utility model describes the above technical solution in detail through the following embodiments:

[0027] A real-time monitoring device for a mine comprises a monitoring machine 1, the monitoring machine 1 is provided with an alarm 11, an air intake fan 2 is provided at the monitoring end of the monitoring machine 1, a filter cover 3 is provided on the air intake fan 2, a reducer 4 is provided inside the filter cover 3, a high-speed shaft of the reducer 4 is drivingly connected with the driving shaft of the air intake fan 2, a filter screen 31 is provided on the filter cover 3, a cleaning shaft 5 is rotatably provided on the filter screen 31, the cleaning shaft 5 is drivingly connected with the low-speed shaft of the reducer 4, a cleaning brush 51 is rotatably provided on the cleaning shaft 5, and the cleaning brush 51 is drivingly connected with the filter cover 3, so that the air intake fan 2 can detect the gas when it is transported to the inside of the monitoring machine 1 through the cooperation of the monitoring machine 1, the alarm 11, the air intake fan 2, the filter cover 3, the filter screen 31, the reducer 4, the cleaning shaft 5 and the cleaning brush 51. During the measurement process, the speed of the driving shaft of the air intake fan 2 is reduced by the reducer 4, and the torque of the cleaning shaft 5 is increased, so that the cleaning shaft 5 cleans the dust filtered on the filter 31. The monitoring machine 1 is also symmetrically provided with an electric push rod 6, and the telescopic end of the electric push rod 6 is rotatably connected to the monitoring machine 1. The electric push rod 6 is provided with a connecting seat 7, and the connecting seat 7 is provided with a handle 8. The handle 8 is provided with a mounting seat 9, and the mounting seat 9 is provided with a mounting hole 91. Therefore, through the cooperation of the electric push rod 6, the connecting seat 7, the handle 8 and the mounting seat 9, not only can the staff install the monitoring machine 1 in the mine and perform a fixed-point complete detection of the mine through the monitoring machine 1, but also the staff can hold the monitoring machine 1 to perform random location detection in the mine.

[0028] like Figures 3 to 5 As shown, a protective net 21 is provided on the air intake fan 2, a first rotating ring 41 is provided on the protective net 21, a first rotating shaft 42 is provided inside the first rotating ring 41, one end of the first rotating shaft 42 is connected to the driving shaft of the air intake fan 2, and the other end of the first rotating shaft 42 is connected to the high-speed shaft of the reducer 4, so that the driving shaft of the air intake fan 2 drives the high-speed shaft of the reducer 4 to rotate through the cooperation of the first rotating ring 41 and the first rotating shaft 42.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, a second rotating ring 43 is provided on the filter screen 31, and a second rotating shaft 44 is provided inside the second rotating ring 43. One end of the second rotating shaft 44 is connected to the low-speed shaft of the reducer 4, and the other end of the second rotating shaft 44 is connected to the cleaning shaft 5. Therefore, through the cooperation of the second rotating ring 43 and the second rotating shaft 44, the low-speed shaft of the reducer 4 drives the cleaning shaft 5 to rotate.

[0030] like Figure 3 and Figure 4As shown, a rotating seat 52 is provided on the cleaning shaft 5, and a brush rod at one end of the cleaning brush 51 is rotatably connected to the rotating seat 52, and a linkage wheel 53 is provided on the brush rod at the other end of the cleaning brush 51, and the linkage wheel 53 is in contact with the filter cover 3, so that through the cooperation of the rotating seat 52, the linkage wheel 53 and the filter cover 3, the cleaning shaft 5 drives the cleaning brush 51 to rotate, so that the cleaning brush 51 rotates by itself, thereby improving the effect of the cleaning brush 51 in cleaning away the dust filtered on the filter net 31.

[0031] like Figure 1 As shown, hinges 61 are symmetrically provided on the monitoring machine 1 , and the telescopic end of the electric push rod 6 is connected to the rotating end of the hinge 61 , so that the electric push rod 6 can rotate on the monitoring machine 1 through the hinge 61 .

[0032] like Figure 1 and Figure 2 As shown, a remote control switch 81 is provided on the connecting seat 7, and a push switch 71 is provided on the handle 8, so that when the staff installs the monitoring machine 1 in the mine, the remote control switch 81 cooperates with the monitoring machine 1 to perform a fixed-point complete detection in the mine, and when the staff holds the monitoring machine 1, the push switch 71 cooperates with the monitoring machine 1 to perform a random location detection in the mine.

[0033] like Figure 1 and Figure 2 As shown, the connecting seat 7 is a rectangular parallelepiped structure, and the handle 8 is a semi-cylindrical structure. When the two handles 8 collide with each other, the two connecting seats 7 and the monitoring machine 1 are in a vertical state. Therefore, through the cooperation between the connecting seat 7 and the handle 8, it is convenient for the staff to hold the monitoring machine 1 to perform random location detection in the mine.

[0034] Working principle: when the monitoring machine 1 detects the inside of the mine, the air intake fan 2 will transport the gas in the mine to the inside of the monitoring machine 1 for detection. During this process, the filter 31 will filter out the dust in the gas. At the same time, the driving shaft of the air intake fan 2 will drive the high-speed shaft of the reducer 4 to rotate at high speed through the first rotating shaft 42 connected to the first rotating ring 41. When the high-speed shaft of the reducer 4 rotates at high speed, it will drive the low-speed shaft of the reducer 4 to rotate at low speed. When the low-speed shaft of the reducer 4 rotates at low speed, it will drive the second rotating shaft 44 connected to the second rotating ring 43 to rotate at low speed. When the second rotating shaft 44 rotates at low speed, it will drive the cleaning shaft 5 to rotate at low speed. When the cleaning shaft 5 rotates at low speed, it will drive the cleaning brush 51 connected to the rotating seat 52 to rotate on the filter 31. When the cleaning brush 51 rotates on the filter 31, it will drive the linkage wheel 53 to roll on the filter cover 3, so that the cleaning brush 51 can clean up the dust filtered on the filter 31.

[0035] When the monitoring machine 1 needs to be installed in the mine, the two electric push rods 6 on the monitoring machine 1 are rotated to a suitable angle, and the monitoring machine 1 can be installed in the mine through the mounting holes 91 on the two mounting seats 9, so that the two electric push rods 6 are started by the remote control switch 81 to control the lifting of the monitoring machine 1 to perform a fixed-point complete detection in the mine. When the monitoring machine 1 needs to be handheld to perform a random location detection in the mine, the two electric push rods 6 on the monitoring machine 1 are rotated until the two handles 8 are in conflict with each other, and the monitoring machine 1 can be moved by holding the two handles 8, so that the two electric push rods 6 are started by pressing the switch 71 to control the extension and retraction of the monitoring machine 1 to perform a random location detection in the mine.

[0036] 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 solution deviate from the scope of the technical solution of the embodiments of the utility model.
