DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a ventilation device for safe production in mines comprises a base 1, wherein the front and rear positions of the top of the base 1 are fixedly connected with brackets 2, the tops of the two brackets 2 are fixedly connected with cylinders 3, the front and rear sides of the cylinder 3 are fixedly connected with screens 5, the middle part of the top of the base 1 is fixedly installed with a first motor 4, the middle part of the inner cavity of the cylinder 3 is fixedly connected with a rectangular box 11, the output end of the first motor 4 extends to the inside of the rectangular box 11, the output end of the first motor 4 is fixedly connected with a first bevel gear 8, the outer wall of the first bevel gear 8 is meshingly connected with two second bevel gears 9, the two second bevel gears 9 are both located inside the rectangular box 11, the ends of the two second bevel gears 9 that are far away from each other extend out of the front and rear sides of the rectangular box 11 respectively, the ends of the two second bevel gears 9 that are far away from each other are fixedly connected with a fan 10, a filtering structure 6 is fixedly installed in front of the fan 10 in front, and a moving structure 7 is fixedly installed at the bottom of the base 1.

[0026] By setting up the filtering structure 6, during the ventilation process, the filter plate 62 filters out dust, mineral powder and other particulates in the air to prevent them from polluting the outside air. The brush 65 is close to the surface of the filter plate 62 and cleans the filter plate 62 while rotating with the first rectangular rod 63. The cleaned debris falls into the collection frame 66. Thereafter, the debris can be further processed by pulling out the pull-out box 67.

[0027] like Figure 2 and Figure 3 As shown, the filtering structure 6 includes a round rod 61, the rear end of the round rod 61 is fixedly connected to the front end of the front fan 10, the front part of the inner cavity of the cylinder 3 is fixedly connected with a filter plate 62, the middle part of the filter plate 62 is rotatably connected to the outer wall of the round rod 61, and the filter plate 62 is located between the opposite surfaces of the front screen 5 and the front fan 10.

[0028] By setting the filter plate 62 and the first motor 4, the two fans 10 are driven to rotate, thereby forming a certain airflow, thereby achieving a ventilation effect. During the ventilation process, the filter plate 62 filters out particles such as dust and mineral powder in the air to prevent them from polluting the outside air.

[0029] like Figure 4As shown, the outer wall of the front part of the round rod 61 is fixedly connected to the first rectangular rod 63, the rear end of the first rectangular rod 63 is fixedly connected to two first elastic telescopic rods 64, the output ends of the two first elastic telescopic rods 64 are fixedly connected to brushes 65, the rear end of the brush 65 overlaps with the front end of the filter plate 62, and the front part of the bottom of the outer wall of the cylinder 3 is fixedly connected to a collecting frame 66, the collecting frame 66 is located in front of the filter plate 62, and the left end of the collecting frame 66 is plugged with a pull-out box 67.

[0030] By arranging the brush 65, when the front fan 10 rotates, the round rod 61 rotates synchronously, thereby making the first rectangular rod 63 and the second rectangular rod 68 rotate synchronously. Under the action of the first elastic telescopic rod 64, the brush 65 is closely attached to the surface of the filter plate 62, and cleans the filter plate 62 while rotating with the first rectangular rod 63. The cleaned debris falls into the collection frame 66, and then the debris can be further processed by pulling out the pull-out box 67.

[0031] like Figure 3 As shown, the outer wall of the rear part of the round rod 61 is fixedly connected to the second rectangular rod 68, the front end of the second rectangular rod 68 is fixedly connected to two second elastic telescopic rods 69, the output ends of the two second elastic telescopic rods 69 are fixedly connected to the balls 610, and the front part of the inside of the cylinder 3 is fixedly connected to a plurality of limit rods 611, the limit rods 611 are located between the filter plate 62 and the opposite surfaces of the balls 610, and the axis of the balls 610 is always located behind the axis of the limit rods 611.

[0032] By setting the ball 610, the second rectangular rod 68 rotates and drives the two balls 610 to rotate at the rear end of the filter plate 62. The ball 610 squeezes the limiting rod 611. Under the action of the second elastic telescopic rod 69, the ball 610 retracts. When the ball 610 breaks away from the limiting rod 611, the ball 610 rebounds and then hits the filter plate 62, causing the filter plate 62 to vibrate, thereby shaking off the debris attached to the surface of the filter plate 62.

[0033] like Figure 5 As shown, the movable structure 7 includes a cavity 71, which is opened inside the bottom of the base 1. Four dampers 72 are fixedly installed on the top of the cavity 71. The bottom ends of the four dampers 72 are fixedly connected to a bottom plate 73, and the bottom of the bottom plate 73 extends out of the bottom end of the base 1.

[0034] By setting the damper 72, when the ventilation device for mine safety production is working, it will vibrate to a certain extent. The damper 72 can achieve a shock-absorbing effect, thereby protecting the ventilation device and achieving a certain noise reduction effect.

[0035] like Figure 5 and Figure 6As shown, a second motor 74 is fixedly installed on the left part of the top of the base 1, and the output end of the second motor 74 extends to the inside of the cavity 71. The output end of the second motor 74 is fixedly connected to a threaded rod 75, and the bottom end of the threaded rod 75 is rotatably connected to the top of the bottom plate 73. The outer wall of the threaded rod 75 is threadedly connected to a pressure plate 76, and the front and rear positions of the left and right parts of the bottom end of the pressure plate 76 are rotatably connected to rollers 77.

[0036] By setting the roller 77, the second motor 74 is driven, which in turn drives the threaded rod 75 to rotate, thereby causing the pressure plate 76 to slide downward inside the cavity 71, and causing the roller 77 to protrude from the bottom end of the bottom plate 73. Thereafter, under the action of the roller 77, the ventilation device for safe production in mines has more convenient mobility, and the second motor 74 is driven in reverse to cause the roller 77 to retract into the cavity 71 again, thereby improving the stability of the ventilation device for safe production in mines when it is placed.

[0037] The working principle of the utility model is as follows: when in use, the second motor 74 is driven, thereby driving the threaded rod 75 to rotate, thereby causing the pressure plate 76 to slide downward inside the cavity 71, thereby causing the roller 77 to protrude from the bottom end of the bottom plate 73. Thereafter, under the action of the roller 77, the ventilation device for safe production in mines is pushed to a suitable position, and then the second motor 74 is driven in the reverse direction, so that the roller 77 is retracted into the cavity 71 again, thereby improving the stability of the ventilation device for safe production in mines in the placed state, starting the first motor 4, thereby driving the two fans 10 to rotate, thereby forming a certain airflow, thereby achieving the ventilation effect. During the ventilation process, the filter plate 62 filters out dust, mineral powder and other particulates in the air to prevent them from polluting the outside air. While the front fan 10 rotates, the round rod 61 rotates synchronously, thereby causing the first rectangular rod 63 and the second rectangular rod 68 to rotate synchronously. Under the action of the elastic telescopic rod 64, the brush 65 is closely attached to the surface of the filter plate 62, and cleans the filter plate 62 while rotating with the first rectangular rod 63. The cleaned debris falls into the collection frame 66, and then the debris can be further processed by pulling out the pull-out box 67. The second rectangular rod 68 rotates while driving the two balls 610 to rotate at the rear end of the filter plate 62. The balls 610 squeeze the limiting rod 611. Under the action of the second elastic telescopic rod 69, the balls 610 retract. When the balls 610 are separated from the limiting rod 611, the balls 610 rebound and then knock on the filter plate 62, causing the filter plate 62 to vibrate, and then the debris attached to the surface of the filter plate 62 is shaken off. When the ventilation device for mine safety production is working, it will vibrate to a certain extent, and the damper 72 can achieve a shock absorption effect, thereby protecting the ventilation device and having a certain noise reduction effect.
