Two auxiliary heat dissipation devices 4 are arranged on the top of the explosion-proof housing 1. The fixing plate 3 and the explosion-proof housing 1 are connected by a rotating device 6. A dust-proof cleaning device 7 is arranged below the explosion-proof housing 1.

[0027] Specifically, the auxiliary heat dissipation device 4 includes a support plate 41, an electric telescopic rod 42, a mesh box 43, a heat dissipation aluminum plate 44, a heat insulation cotton 45 and a moving frame 48. Two support plates 41 are installed on one side of the explosion-proof housing 1 close to the fixing plate 3. Two moving frames 48 are arranged between the two support plates 41. The support plate 41 and the moving frame 48 are connected by an electric telescopic rod 42. Two heat dissipation aluminum plates 44 are installed on the top of the explosion-proof housing 1 and below the two moving frames 48. A heat insulation cotton 45 is installed on the moving frame 48 and above the heat dissipation aluminum plate 44. A mesh box 43 is installed on the moving frame 48 and at a position between the heat insulation cotton 45 and the support plate 41.

[0028] By adopting the above technical solution, the monitor can assist in dissipating heat inside the explosion-proof housing 1 through the cooperation of structures such as the heat dissipation aluminum plate 44 when needed, thereby reducing the possibility of overheating and damage to the internal structures of the explosion-proof housing 1.

[0029] Specifically, the auxiliary heat dissipation device 4 further includes a fan blade 46 and a rotating motor 47. A plurality of rotating motors 47 are installed above the mesh box 43. A fan blade 46 is installed on the outer side of the output end of the rotating motor 47 and at a position inside the mesh box 43.

[0030] By adopting the above technical solution, after the mesh box 43 moves above the heat dissipation aluminum plate 44, each rotating motor 47 can be started to drive each fan blade 46 to rotate, thereby accelerating the air flow around the heat dissipation aluminum plate 44 and ensuring the effect of auxiliary heat dissipation.

[0031] Specifically, the rotating device 6 includes a reduction motor 61 and a connecting sleeve 64. A reduction motor 61 is installed on one side of the fixing plate 3 close to the explosion-proof housing 1. A connecting sleeve 64 is installed on the outer side of the output end of the reduction motor 61 and close to the explosion-proof housing 1.

[0032] By adopting the above technical solution, the staff can adjust the angle of the explosion-proof housing 1 through the cooperation of the power-off braking reduction motor 61 and other structures when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the rotating device 6 further includes a spring pin 62 and a connecting block 63. The connecting block 63 is installed on the explosion-proof housing 1 at a position inside the connecting sleeve 64, and the connecting sleeve 64 and the connecting block 63 are connected by two spring pins 62.

[0034] By adopting the above technical solution, the staff can connect or disconnect the connecting sleeve 64 and the explosion-proof housing 1 when needed, thus facilitating the loading and unloading of the explosion-proof housing 1 and other structures by the staff when needed.

[0035] When this embodiment is in use, when the mine needs to use the monitor, the fixing plate 3 is fixed at the working position by screws, and then the corresponding optical fibers are connected to the input / output ports 5. The reduction motor 61 in the rotating device 6 is started, and the reduction motor 61 drives the connecting sleeve 64 to rotate. The connecting sleeve 64 drives the explosion-proof housing 1 and other structures to rotate to the required position through the spring pins 62 and the connecting block 63. Then, the anti-interference component 2 is operated to receive signals and play videos through the display screen component 8, and then it can be used. During the use process, the staff can start the electric telescopic rods 42 on the support plates 41 of the two auxiliary heat dissipation devices 4, so as to drive the two moving frames 48 to move until the two heat insulation cotton 45 move away from above the two heat dissipation aluminum plates 44 and the two mesh boxes 43 move above the two heat dissipation aluminum plates 44. The heat in the explosion-proof housing 1 is discharged through the two heat dissipation aluminum plates 44, and then each rotating motor 47 is started to drive each fan blade 46 to rotate, thereby improving the heat dissipation efficiency.

[0036] Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the dust-proof cleaning device 7 includes a toughened glass plate 71, a connecting box 72, a mounting plate 73, a fan 76 and an air outlet net 77. The toughened glass plate 71 is arranged below the explosion-proof housing 1, and connecting boxes 72 are installed on both sides of the toughened glass plate 71. A mounting plate 73 is installed on the side of the connecting box 72 away from the toughened glass plate 71. A plurality of fans 76 are installed on the connecting box 72 at a position below the mounting plate 73. An air outlet net 77 is installed on the side of the connecting box 72 away from the plurality of fans 76 near the edge.

[0038] By adopting the above technical solution, the monitor can prevent dust and other substances from staying and adhering to the toughened glass plate 71 through the flow of air when needed, thus ensuring the viewing effect of the staff and further ensuring the normal progress of the work.

[0039] Specifically, the dust-proof cleaning device 7 further includes a buckle 74, and the explosion-proof housing 1 and the two mounting plates 73 are connected by two buckles 74.

[0040] By adopting the above technical solution, the staff can connect or disconnect the explosion-proof shell 1 and the two mounting plates 73 when needed, thus facilitating the staff to load and unload structures such as the two mounting plates 73 when needed.

[0041] Specifically, the dust-proof cleaning device 7 further includes a partition net 75, and the partition net 75 is installed inside the air inlet end of the fan 76.

[0042] By adopting the above technical solution, the monitor can isolate and block external impurities through the partition net 75, thereby preventing external impurities from entering the interior of the fan 76, and further reducing the possibility of accidental damage to the fan 76.

[0043] When in use in this embodiment, when the staff is watching, the transparent tempered glass plate 71 in the dust-proof cleaning device 7 will not affect the viewing effect. The staff can start each fan 76, and each fan 76 sends the clean air filtered by the partition net 75 into the two connection boxes 72, and then the air passes through the two air outlet nets 77 and is discharged, thereby preventing dust and other substances from staying and adhering to the tempered glass plate 71, ensuring the viewing effect of the staff. The mounting plate 73 and the buckle 74 play a role in connection and installation.

[0044] In the present invention, the structures and principles of the explosion-proof shell 1, the anti-interference component 2 composed of a phenolic board, an AC-DC voltage converter, a video synthesis circuit, a video driving circuit, a display backlight circuit, an optical fiber to composite video module, and a transformer, the input / output port 5, and the display component 8 composed of tempered glass and a liquid crystal display are already disclosed in a mine monitor disclosed in Chinese Patent Application No. 201220065649.8. Its working principle is as follows: First, connect the underground power supply and the monitor power input bell mouth with a special mine-use power cable. Then, open the monitor video signal wiring bell mouth and the rear cover, connect the video signal optical fiber or cable to their respective sockets through the bell mouth. Finally, carefully check whether the positions of all connected cables are correct. After confirming that there is no error, restore the rear cover of the mine monitor, tighten the bell mouth, and power on for use. The monitor with an explosion-proof shell increases the explosion-proof function of the circuit and can be used in coal mines. It can simultaneously input composite video signals and synthesize them into a same-screen signal for display, expanding the monitoring area and range. It can input both composite video signals and optical fiber analog video signals, increasing the signal transmission distance and improving the anti-interference ability. This monitor can be used for real-time monitoring of underground long-distance operation conditions or for monitoring the working conditions of each action point of the front drill on a mine remote control drill.

[0045] Working principle and usage process of the present invention: When a monitor is needed in a mine, the fixing plate 3 is fixed at the working position through screws, and then the corresponding optical fiber is connected to the input / output port 5. The reduction motor 61 in the rotating device 6 is started, and the reduction motor 61 drives the connecting sleeve 64 to rotate. The connecting sleeve 64 drives structures such as the explosion-proof shell 1 to rotate to the required position through the spring pin 62 and the connecting block 63. Then, the anti-interference component 2 is operated to receive signals and play videos through the display component 8, and thus it can be used. During the use process, the staff can start the electric telescopic rods 42 on the support plates 41 of the two auxiliary heat dissipation devices 4, so as to drive the two movable frames 48 to move until the two heat insulation cotton 45 move away from above the two heat dissipation aluminum plates 44 and the two mesh boxes 43 move to above the two heat dissipation aluminum plates 44. The heat in the explosion-proof shell 1 is discharged through the two heat dissipation aluminum plates 44, and then each rotation motor 47 is started to drive each fan blade 46 to rotate, so as to improve the heat dissipation efficiency; when the staff is watching, the transparent tempered glass plate 71 in the dust-proof cleaning device 7 will not affect the viewing effect. The staff can start each fan 76, and each fan 76 sends the clean air filtered by the partition net 75 into the two connecting boxes 72, and then the air is discharged through the two air outlet nets 77, so as to prevent dust and other substances from staying and adhering to the tempered glass plate 71, ensuring the viewing effect of the staff. The mounting plate 73 and the buckle 74 play a role in connecting and installing.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
