[0040] It is easy to understand that the early warning host 1 is a controller with built-in program, such as PLC, which is a mature design in the art; the program used by the early warning host 1 is used to compare the detection value of the monitoring instrument 2 with the preset value, which is a mature design that can be realized by simple programming by those skilled in the art, and will not be described here.

[0041] Specifically, the mounting plate 12 is a rectangular plate, and the four corners of the rectangular plate are provided with mounting portions 121 extending out of the early warning host 1, and the mounting portions 121 are provided with mounting holes 122, and the mounting plate 12 is used to be fixed on the inner wall of the mine through screws penetrating the mounting holes 122.

[0042] More specifically, the mounting plate 12 and the early warning host 1 can be fixed by welding, one-piece molding or the like.

[0043] It should be noted that the number of data interfaces 13 should be greater than or equal to the number of mounting positions 11, and on the basis of being able to ensure that all monitoring instruments 2 are connected, several data structures can be reserved for standby, such as connecting a mobile phone or other electronic devices. For example, the mounting position 11 of the embodiment is provided with two, and the data interface 13 is provided with four.

[0044] Further, the embodiment also opens a heat dissipation window 14 on the front side wall of the early warning host 1 to avoid excessive temperature.

[0045] It is easy to understand that the early warning host 1 can be built-in battery to power each electronic device, or can be externally powered.

[0046] Among them, the monitoring instrument 2 corresponds to the mounting position 11 one by one, the monitoring instrument 2 includes a module base 21, an instrument body and a data line 23, the module base 21 is detachably fixed in the corresponding mounting position 11, the instrument body is connected to the module base 21, and one end of the data line 23 is electrically connected with the instrument body and the other end is inserted into the data interface 13. In use, select the appropriate monitoring instrument 2 and then fix it on the mounting position 11 through the module base 21, and insert the data line 23 into the data interface 13 to realize the communication connection with the early warning host 1.

[0047] Specifically, the mounting position 11 is a clamping groove, and the module base 21 is clamped in the clamping groove to realize detachable fixing. The clamping groove realizes the clamping and detachable fixing of the module base 21, and the structure is relatively simple and the performance is relatively reliable.

[0048] More specifically, the card slot is a T-shaped rectangular slot, and the T-shaped rectangular slot is a slot structure in which a baffle 111 is arranged at both ends of the lower part of the slot opening of the rectangular slot to form a T-shaped slot opening. The left and right sides of the module base 21 are both provided with an insertion slot 211, and the module base 21 is clamped on the card slot through the insertion slot 211 and the baffle 111. In use, first, the module base 21 is inserted into the rectangular slot from the upper part of the T-shaped slot opening, and then moved downward until the insertion slot 211 is clamped on the baffle 111. The reverse operation can be performed when disassembling. This clamping structure can ensure the stability of the clamping by using the self-weight of the structure, and the assembly and disassembly are also relatively convenient.

[0049] It should be noted that the monitoring instrument 2 of the device can be selected according to the use requirements, such as a gas detector 221, a monitoring camera 222, a dust detector, a temperature and humidity detector, etc. For example, the early warning host 1 of the embodiment is provided with two upper and lower installation positions 11, respectively installed with the monitoring instrument 2 with the instrument body being the gas detector 221 and the monitoring instrument 2 with the instrument body being the monitoring camera 222.

[0050] It is easy to understand that the gas detector 221 and the monitoring camera 222 are both mature structures in the field, the gas detector 221 is used to monitor the concentration of harmful gases such as gas in the mine, and the monitoring camera 222 is used to monitor the changes of the inner wall of the mine, so as to timely alarm when cracks or other accidents occur in the inner wall of the mine.

[0051] It should be noted that the instrument body can be directly purchased from existing mature products, and then the instrument body is fixed on the module base 21 of the device by welding or magnetic attraction, etc., so as to form the monitoring instrument 2 of the device.

[0052] Further, the monitoring camera 222 of the embodiment is connected with the corresponding module base 21 through the cross drive frame 4, and the cross drive frame 4 comprises:

[0053] The L-shaped piece 41 is fixedly connected with the corresponding module base 21;

[0056] The first L-shaped bracket 44 is fixedly sleeved on the output shaft of the first motor 42;

[0057] A ball head rod 45, a rod part 451 of which is rotatably inserted into the second end of the first L-shaped frame 44 and horizontally arranged, the rod part 451 penetrates through the first L-shaped frame 44 and is fixedly connected with the monitoring camera 222, and a ball center of a ball part 452 of the ball head rod 45 is located at the intersection of the axis of the first motor 42 and the axis of the second motor 43;

[0058] A second L-shaped frame 46, a first end of which is fixedly sleeved on the output shaft of the second motor 43;

[0059] A linkage shaft 47, which is rotatably inserted into the second end of the second L-shaped frame 46 and is perpendicular to the output shaft of the first motor 42, the extension line of the linkage shaft 47 passes through the ball center of the ball head rod 45 and is slidingly connected to the surface of the ball part 452 of the ball head rod 45, and the axis of the sliding track of the linkage shaft 47 is perpendicular to the rod part 451 of the ball head rod 45.

[0060] The initial state is shown in Figure 5 The output shaft of the first motor 42 is coaxial with the linkage shaft 47, the output shaft of the second motor 43 is coaxial with the rod part 451 of the ball head rod 45, the monitoring camera is horizontally arranged and faces vertically to the ball head rod 45. In use, when the first motor 42 is controlled to act by the early warning host 1, the output shaft of the first motor 42 drives the first L-shaped frame 44 to rotate, thereby adjusting the direction of the monitoring camera 222, and further realizing the horizontal movement of the field of view of the monitoring camera 222 to monitor the inner wall of the mine in a larger range; if it is necessary to monitor the upper or top inner wall of the mine, first, the first motor 42 is reset to the initial state, and then the second motor 43 is controlled to act by the early warning host 1, so that the output shaft of the second motor 43 drives the second L-shaped frame 46 to rotate by 90°, and the second L-shaped frame 46 drives the ball head rod 45 and the monitoring camera 222 to rotate by 90° through the linkage shaft 47, and then cooperates with the action of the first motor 42 to realize the rotation of the field of view of the monitoring camera 222 around the axis of the first motor 42, thereby monitoring the top and upper inner wall of the mine.

[0061] It should be noted that the monitoring camera 222 with a vertical field of view angle greater than 45° should be selected, so that the horizontal monitoring and vertical monitoring can partially overlap, thereby realizing the monitoring of all inner walls through the program control of the early warning host 1.

[0063] Among them, the buzzer 3 is arranged on the top of the early warning host 1 and is in communication connection with the early warning host 1.

[0064] It is easy to understand that the buzzer 3 is a mature structure in the art, when the gas detector 221 monitors that the concentration of gas such as gas is greater than the set value, or when the picture of the inner wall of the mine taken by the monitoring camera 222 has cracks and other unexpected situations compared with the standard picture, the warning host 1 controls the buzzer 3 to start to remind the workers that there is a safety hazard.

[0065] The working principle of the modular coal mine underground goaf safety monitoring device of the embodiment is as follows:

[0066] After the staff arrives at the designated position, the installation plate 12 is attached to the sidewall of the mine, and then the device is fixed on the wall surface through screws, then the gas detector 221 and the monitoring camera 222 are clamped on the two installation positions 11 through the module base 21, finally the data line 23 is inserted into the data interface 13 at the bottom of the warning host 1, the gas detector 221 monitors the concentration of harmful gases such as gas in the mine, the monitoring camera 222 monitors the changes of the inner wall of the mine, and the warning host 1 controls the first motor 42 and the second motor 43 to act at the set interval according to the preset program, so as to adapt to the orientation and state of the monitoring camera 222, when an abnormality occurs, the warning host 1 starts the buzzer 34 to alarm and prompt the workers to evacuate, so as to ensure the safety of the workers.
