Description

Technical Field

[0001] This utility model relates to the field of mine safety technology, specifically a mine safety warning device. Background Technology

[0002] Mines often contain many complex underground areas. To prevent workers from accidentally entering these areas, warning devices are usually placed outside the danger zones to alert them.

[0003] As in the prior art, a safety warning device for mine safety (CN221702173U) can protect the warning light by using a protective cover mounted on a mounting frame, preventing the warning light from being damaged by direct contact with the ground when the device is accidentally tipped over. The protective cover can be disassembled by the cooperation of annular plate and annular groove, making it easy to replace the protective cover when it is damaged. It is convenient to operate. Moreover, it can be used with a square tube and a square rod. When the height of the device needs to be adjusted, first pull out the pin, then adjust the device so that the square rod slides in the square tube. When the desired height is reached, align the through hole with the slot and insert the pin to fix the adjusted height.

[0004] However, since the warning device is located in a mine, where dust is abundant, the surface of the warning light is easily covered with a thick layer of dust. As a result, when the warning light flashes to sound an alarm, the dust can affect the visibility of the light, thereby reducing the warning effect. Therefore, those skilled in the art have proposed a mine safety warning device to solve the problems mentioned in the background. Utility Model Content

[0005] The purpose of this utility model is to provide a warning device for mine safety to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mine safety warning device includes a base, a support column mounted on the base, a support platform mounted on the support column, a warning light mounted on the support platform, a rotating shaft rotatably mounted inside the support platform, a rotating frame mounted on the rotating shaft, a plurality of sliders arranged in a ring at intervals mounted on the rotating frame, a plurality of arc-shaped grooves slidably connected to the sliders on the support platform, a ring frame fixedly connected to the sliders, and a plurality of scrapers arranged at intervals and conforming to the outer surface of the warning light mounted on the ring frame, further comprising:

[0008] A pulling component is disposed within the support column and support platform and is used to drive the rotating shaft to rotate.

[0009] As a further embodiment of this utility model: the pulling component includes a mounting block installed on the inner wall of the support platform, a movable shaft rotatably arranged inside the mounting block, a winding roller mounted on the movable shaft, a pull rope wound on the winding roller, a guide wheel rotatably arranged at the bottom of the support column, the pull rope passing around the guide wheel and connecting to a pull ring outside the support column, a coil spring connected to the movable shaft is provided inside the mounting block, and the movable shaft and the rotating shaft are connected by a transmission component.

[0010] As a further embodiment of this utility model: the transmission component includes a second bevel gear installed at the bottom of the rotating shaft, and a first bevel gear meshing with the second bevel gear is installed on the movable shaft.

[0011] As a further improvement of this utility model: a protective rod is installed on the support platform, and a cover plate is installed on the top of the protective rod.

[0012] As a further improvement of this utility model, several insertion rods are installed at the bottom of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the warning device is moved to the position where warning is needed, and then the base is fixed to that position by the plug rod. The warning light on the support platform provides warning. When the surface of the warning light is covered with a thick layer of dust, affecting the visibility of the warning light, the worker can pull the component next to the support column to make the rotating shaft rotate, thereby driving the rotating frame to rotate. The rotating frame drives the ring frame to rotate through the slider, thereby driving the scraper on the ring frame to clean the dust on the surface of the warning light. The effect of use is better. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] Please see Figures 1-5 A mine safety warning device includes a base 1, a support column 2 mounted on the base 1, a support platform 3 mounted on the support column 2, a warning light 6 mounted on the support platform 3, a rotating shaft 7 rotatably disposed within the support platform 3, a rotating frame 8 mounted on the rotating shaft 7, and a plurality of annularly spaced sliders 9 mounted on the rotating frame 8. The support platform 3 has a plurality of arc-shaped grooves 10 that slidably connect with the sliders 9. The sliders 9 are fixedly connected to an annular frame 11, and a plurality of spaced scrapers 12 that are in contact with the outer surface of the warning light 6 are mounted on the annular frame 11. The device also includes:

[0022] A pulling component is disposed within the support column 2 and the support platform 3, and is used to drive the rotating shaft 7 to rotate.

[0023] When in use, the warning light 6 on the support platform 3 provides a warning. When the surface of the warning light 6 is covered with a thick layer of dust, affecting the visibility of the light, the worker can pull the component next to the support column 2 to make the rotating shaft 7 rotate, thereby driving the rotating frame 8 to rotate. The rotating frame 8 drives the ring frame 11 to rotate through the slider 9, thereby driving the scraper 12 on the ring frame 11 to clean the dust on the surface of the warning light 6, resulting in better performance.

[0024] In one embodiment, the pulling assembly includes a mounting block 13 installed on the inner wall of the support platform 3. A movable shaft 14 is rotatably disposed within the mounting block 13, and a winding roller 18 is mounted on the movable shaft 14. A pull rope 19 is wound on the winding roller 18. A guide wheel 20 is rotatably disposed at the bottom of the support column 2. The pull rope 19 passes around the guide wheel 20 and connects to a pull ring 21 outside the support column 2. A coil spring 15 connected to the movable shaft 14 is disposed within the mounting block 13. The movable shaft 14 and the rotating shaft 7 are connected by a transmission component. The transmission component includes a second bevel gear 17 mounted at the bottom of the rotating shaft 7, and a first bevel gear 16 meshing with the second bevel gear 17 is mounted on the movable shaft 14.

[0025] When it is necessary to drive the rotating shaft 7 to rotate the scraper 12 to clean the dust covering the warning light 6, the pull ring 21 can be pulled outward, which in turn pulls the pull rope 19, causing the winding roller 18 to rotate, which in turn drives the movable shaft 14 to rotate. Then, through the meshing first bevel gear 16 and second bevel gear 17, the rotating shaft 7 can be driven to rotate, thereby driving the scraper 12 to rotate around the warning light 6 through the rotating frame 8, slider 9 and ring frame 11, so that the scraper 12 can clean the dust on the surface of the warning light 6. When the pull ring 21 is released, the movable shaft 14 rotates in the opposite direction under the action of the coil spring 15, causing the winding roller 18 to start winding the pull rope 19 until the pull ring 21 is stuck on the outer wall of the support column 2, realizing the reset.

[0026] In one embodiment, a protective rod 4 is installed on the support platform 3, and a cover plate 5 is installed on the top of the protective rod 4.

[0027] Multiple protective rods 4 arranged in a ring can protect the warning light 6, preventing it from colliding with large objects and causing damage. The cover plate 5 can also protect the top of the warning light 6, preventing falling objects from directly damaging it.

[0028] In one embodiment, a plurality of insert rods 22 are installed at the bottom of the base 1.

[0029] Insert the plug 22 into the ground to fix the base 1.

[0030] In use, this utility model involves moving the warning device to the desired location and then fixing the base 1 to that location using the insert rod 22. The warning light 6 on the support platform 3 provides the warning. When the surface of the warning light 6 is covered with a thick layer of dust, affecting its visibility, the worker can pull the assembly next to the support column 2 to rotate the shaft 7, thereby driving the rotating frame 8 to rotate. The rotating frame 8 then drives the ring frame 11 to rotate via the slider 9, which in turn drives the scraper 12 on the ring frame 11 to clean the dust off the surface of the warning light 6. This method is highly effective.
