Description

Technical Field

[0001] This utility model relates to the field of alarms, specifically a ventilation and alarm device for coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to mine the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is usually stripped away to mine the coal; this is called an open-pit coal mine. The environment inside a coal mine is complex, with a large amount of dust, gas, and other dangerous factors. When danger occurs, the mine's ventilation and alarm equipment needs to report the danger so that workers inside the mine can take timely measures.

[0003] Existing coal mine ventilation alarm devices often have sound and flashing effects to provide workers with dual alerts. However, coal mines contain a large amount of dust, which can cover the alarm devices, reducing the sound and flashing effects and resulting in poor alarm performance. Workers cannot receive the signal in time to react. Therefore, a new coal mine ventilation alarm device is proposed. Utility Model Content

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.

[0024] A coal mine ventilation and alarm device, such as Figures 1-5 As shown, the device includes a housing 1, one side of which is fixed to the side wall of a coal mine. A dustproof plate 4 and a warning light 5 are fixed to one side of the housing 1. An arc plate 8 is rotatably installed on the outside of the housing 1. The shape of the arc plate 8 is adapted to the shape of the end of the warning light. A cleaning sleeve 9 is fitted on the outside of the arc plate 8. One side of the cleaning sleeve 9 is attached to the surface of the warning light 5 to remove dust from the surface of the warning light 5. The cleaning sleeve 9 is elastic and easy to replace. A vibration component is provided on the inner wall of the housing 1. The end of the vibration component is used to strike the dustproof plate 4, causing the dustproof plate 4 to vibrate, so that dust will not remain on the dustproof plate 4 or will be shaken off. A sound alarm is fixed inside the housing 1. The sound output end of the sound alarm is facing the dustproof plate 4. The sound emitted by the sound alarm passes through the dustproof plate 4 to trigger the alarm.

[0025] This coal mine ventilation and alarm equipment features both audible and flashing alarms. A dustproof plate 4 and a warning light 5 are installed on the housing 1 of the alarm equipment. The dustproof plate 4 prevents dust from contacting the audible alarm inside the housing 1, and the vibrating component intermittently strikes the dustproof net to prevent dust from accumulating on the net. The rotating arc plate 8 causes the cleaning sleeve 9 to scrape the surface of the warning light 5, removing dust from the surface of the warning light 5. This coal mine ventilation and alarm equipment can prevent dust from accumulating on the warning light 5 and the audible alarm, making it suitable for coal mine environments.

[0026] The shell 1 is shaped as a triangular prism with a cross-section that can be a right triangle or an obtuse triangle. A mounting plate 2 is fixed to the side of the triangular prism with the largest area. The mounting plate 2 is installed on the side wall of the coal mine by expansion bolts. The dustproof plate 4 and the warning light 5 are located on the same side of the shell 1 and on the side of the shell 1 that is tilted downwards after installation, so that dust is not easy to fall from top to bottom onto the dustproof plate 4 or the warning light 5. A guide plate 3 is fixed to the end of the shell 1 away from the mounting plate 2. The guide plate 3 is smoothly connected to one side of the shell 1. The surface where the dustproof plate 4 is located is not smoothly connected to the guide plate 3. When dust falls onto the shell 1 from top, some dust will fall down along the tilted shell 1 and the guide plate 3, further reducing the dust retention rate on the surface of the shell 1.

[0027] The housing 1 of this alarm device has a shape that reduces dust accumulation without affecting the sound and flashing alert effects. It is tilted downwards, which, compared to being vertically downwards, provides better propagation and observation effects.

[0028] A toothed ring 6 is rotatably mounted on one side of the housing 1, a warning light 5 is located inside the toothed ring 6, and one end of an arc plate 8 is located on the toothed ring 6.

[0029] The toothed ring 6 drives the arc plate 8 to rotate, causing the cleaning sleeve 9 to surround the surface of the warning light 5 and scrape off the dust on the surface of the warning light 5.

[0030] A fixed ring 10 is fixedly connected to one side of the gear ring 6. The fixed ring 10 is rotatably mounted on the side wall of the housing 1. A spur gear 7 is rotatably mounted on one side of the housing 1. The spur gear 7 meshes with the gear ring 6 for transmission. A motor 11 is fixedly connected inside the housing 1. The output end of the motor 11 is fixedly connected to the middle of the spur gear 7.

[0031] The retaining ring 10 prevents the toothed ring 6 from falling off the housing 1. The motor 11 drives the flat gear 7 to rotate, which causes the toothed ring 6 to drive the arc plate 8 to rotate.

[0032] The vibration assembly includes a bracket 12, which is fixed to the inner wall of the housing 1. A rotating wheel 13 is rotatably mounted on one side of the bracket 12, and a rod 18 is fixed to one side of the rotating wheel 13. A ball 21 that strikes the dustproof plate 4 is fixed to the end of the rod 18.

[0033] A fixing block 19 is fixedly connected to the side wall of the rod 18, and a spring 20 is fixedly connected to one side of the fixing block 19. The end of the spring 20 is fixedly connected to the inner wall of the housing 1, and the spring 20 is in a stretched state.

[0034] The rotating wheel 13 drives the rod 18 to rotate, causing the ball 21 to move away from the dustproof plate 4. The spring 20 then stretches the rod 18, causing the ball 21 to strike the dustproof plate 4.

[0035] A second motor 15 is fixedly connected to the inner wall of the housing 1. A second rotating wheel 16 is fixedly connected to the output end of the second motor 15. A toothed gear set 14 is fixedly connected to the first rotating wheel 13. A toothed gear set 17 is fixedly connected to the second rotating wheel 16. The toothed gear set 14 and the toothed gear set 17 mesh and drive each other to rotate the rod 18.

[0036] Both motor 11 and motor 25 are model TF-N20F. Motor 215 drives wheel 216 to rotate. After wheel 216 rotates to a certain angle, tooth group 217 meshes with tooth group 14, driving wheel 13 to rotate. Wheel 13 drives ball 21 away from dust plate 4 through rod 18. After tooth group 21 meshes with tooth group 14 to a certain angle, tooth group 21 disengages from tooth group 14, wheel 13 is released from restriction, spring 20 pulls rod 18 to reset, causing ball 21 to strike dust plate 4.

[0037] The working principle of the coal mine ventilation and alarm device provided by this utility model is as follows:

[0038] This coal mine ventilation alarm system features both audible and flashing alarms. A dustproof plate 4 and a warning light 5 are installed on a triangular prism-shaped housing 1. The dustproof plate 4 prevents dust from contacting the audible alarm inside the housing 1. Motor 2 15 drives wheel 2 16 to rotate. After wheel 2 16 rotates a certain angle, the toothed gear assembly 2 17 meshes with the toothed gear assembly 14, driving wheel 1 13 to rotate. Wheel 1 13, via rod 18, drives ball 21 away from the dustproof plate 4. The toothed gear assembly 2 17 then meshes with the toothed gear assembly 14. After moving a certain angle, the second tooth assembly 17 disengages from the first tooth assembly 14, the first rotating wheel 13 is released from its restraint, the spring 20 pulls the rod 18 back to its original position, causing the ball 21 to strike the dustproof plate 4, preventing dust from covering the dustproof net. The motor 11 drives the flat gear 7 to rotate, causing the gear ring 6 to drive the arc plate 8 to rotate. The cleaning sleeve 9 scrapes the surface of the warning light 5 to remove dust from the surface of the warning light 5. This coal mine ventilation alarm device can prevent dust from covering the warning light 5 and the sound alarm, and is suitable for the coal mine environment.
