Description

Technical Field

[0001] The present invention relates to the technical field related to mine safety ventilation equipment, and in particular to mine safety and environmentally friendly ventilation equipment. Background Art

[0002] Ventilation management is a crucial component of safe mine production. Mine ventilation ensures sufficient fresh air underground, allowing workers to work safely and preventing discomfort from oxygen deprivation. This improves the working environment and ensures their safety. Therefore, systematic and scientific management of mine ventilation safety, tailored to the specific conditions of the mine, is essential and crucial for safe mine production. Mine dust is a common and highly hazardous pollutant in mining operations. Dust not only affects the working environment but also poses a serious threat to worker health. Physical factors are a major contributor to dust generation during mining. For example, ore crushing, screening, and transportation generate significant amounts of dust. Furthermore, as mining depth increases, changes in ground pressure can cause ore fragmentation, further generating more dust. Environmental conditions significantly influence the generation and spread of mine dust. Dry, windy environments are more prone to dust being blown up and disseminated over a wider area. Spraying is commonly used to reduce dust. Water droplets adhere to the dust, causing it to fall to the ground quickly under the action of gravity. However, multiple spraying is required, making it difficult to control the humidity inside the mine. The temperature inside the mine is high for various reasons, resulting in a high temperature and high humidity environment inside the mine, which causes a series of health problems for workers. At the same time, the high temperature and high humidity environment may also cause equipment damage and electrical accidents. At the same time, the dust reduced by water curtain spraying will fall to the ground and is difficult to collect, making the humidity inside the mine difficult to control. Summary of the Invention

[0027] Method of use of the present invention:

[0028] In the initial state:

[0029] The No. 1 connecting rod 27 and the electric push rod 28 are both in a retracted state, the movable plate 18 is in contact with the fixed cylinder 17, the fixed cylinder 17 and the movable plate 18 are perpendicular to the ground, the ventilation pipe 14 and the connecting plate 15 are both connected to the corresponding external pipelines, the torsion spring 37 is in a tightened state, and the scraper 39 is located at one end close to the torsion spring 37.

[0030] When the user needs to use the device, the user needs to move the device inside the mine so that the fixing plate 13 is attached to one side of the mine tunnel, and then the present invention can be started, and the external gas enters the ventilation pipe 14 through the external pipeline, and then under the action of the control terminal 12, the motor in the ventilation pipe 14 is started, thereby driving the fan 36 to rotate, thereby completing the ventilation in the mine. Under the action of the control terminal 12, the nozzle 44 is started, and the water transported by the external pipeline is sprayed out, so that an appropriate amount of moisture is attached to the surface of the mine to reduce dust. After a certain period of time, the moisture on the surface of the mine is about to evaporate, and the control terminal 12 will drive the nozzle 44 again to complete the spraying, and so on. , thereby controlling the humidity in the mine and reducing surface dust. When a transport vehicle passes through the mine or other reasons bring up dust, and the dust concentration in the air reaches a certain level, it will be detected by the dust sensor 16, and then the dust sensor 16 will be triggered, thereby transmitting a signal to the control terminal 12. After the control terminal 12 receives the signal transmitted by the dust sensor 16, the motor in the ventilation pipe 14 will stop starting, the fan 36 will stop rotating, and the No. 1 motor 22 will start. After the No. 1 motor 22 starts, its motor shaft will drive the fixed cylinder 17 to rotate, thereby driving the fixed cylinder 17 and the movable plate 18 to move in the direction of the No. 1 screw 19 and the limit rod 20. The rotation is close to 90 degrees, but the whole still has a certain inclination. The end of the blocking film 33 close to the base 11 is at a lower position, so that the fixed cylinder 17 is parallel to the ground, and then the No. 2 motor 21 will be started under the action of the control terminal 12. After the No. 2 motor 21 is started, its motor shaft will drive the No. 1 screw 19 to rotate, so that the movable plate 18 moves in the direction away from the fixed cylinder 17, so that the blocking film 33 is pulled out, the reel 41 rotates, and then the No. 4 motor 26 and the electric push rod 28 will be started under the action of the control terminal 12. After the No. 4 motor 26 is started, its motor shaft will drive the No. 1 connecting rod 27 and the No. 2 connecting rod 29 to rotate. The electric push rod 28 begins to extend, thereby driving the telescopic rod 31 to extend, so that the drainage tube 30 moves to the center of the mine, and then the air pump 23 will be started, thereby starting to suck through the drainage tube 30, thereby driving the dust on both sides to move toward the drainage tube 30, and then the control terminal 12 will start the nozzle 44 to spray, so that the dust falls quickly on the blocking film 33 under the action of the spray, and the dust sucked by the drainage tube 30 will enter the dust collecting box 24 and be blocked by the filter, thereby greatly accelerating the dust falling speed and controlling the humidity in the mine, thereby preventing the mine from causing a high humidity environment due to spraying, affecting the health of the workers, until a certain time later,When the dust sensor 16 detects that the dust concentration is low and has not reached the trigger value, the No. 4 motor 26, the electric push rod 28, and the No. 2 motor 21 will start. After the electric push rod 28 starts, it will begin to shrink, thereby driving the drainage tube 30 and the No. 2 connecting rod 29 to reset. After the No. 4 motor 26 starts, it starts to rotate, thereby driving the No. 1 connecting rod 27, the No. 2 connecting rod 29, and the drainage tube 30 to reset. Then the No. 2 motor 21 will start. After the No. 2 motor 21 starts, it will drive the movable plate 18 to return to its original position. The barrier film 33 is in position, and since the barrier film 33 is in close contact with the inlet and outlet side walls of the fixed cylinder 17, the dust and water droplets will be scraped off by the inlet and outlet side walls and will not enter the fixed cylinder 17, but will accumulate on the barrier film 33 between the fixed cylinder 17 and the movable plate 18. The torsion spring 37 resets and drives the reel 41 to rotate, thereby keeping the barrier film 33 always taut. When the barrier film 33 is rolled up, the water droplets on the upper part thereof accumulate to a certain extent and, under the action of gravity, will preferentially fall into the barrier film 33 with the dust on the barrier film 33. The dust box 32 and the water collecting box 45 are in the dust collecting box 32 and the water collecting box 45 until the movable plate 18 is completely reset. At this time, the No. 3 motor 42 and the No. 1 motor 22 will be started. After the No. 3 motor 42 is started, its motor shaft will drive the No. 2 screw 38 to rotate, thereby driving the scraper 39 to move toward the No. 1 motor 22, thereby scraping off water droplets and dust. After the No. 1 motor 22 is started, it will drive the fixed cylinder 17 and the movable plate 18 to reset, and the water droplets and dust scraped by the scraper 39 will fall into the inlet 43 under the action of gravity. The dust falls into the dust box 32, thereby controlling the humidity inside the mine and preventing the ground from becoming excessively muddy due to spraying. Then, the third motor 42 is restarted under the action of the control terminal 12, thereby driving the scraper 39 to reset. Then, under the action of the control terminal 12, the motor in the ventilation pipe 14 is restarted, causing the fan 36 to rotate again, thereby ensuring ventilation in the mine. After a certain period of time, the user needs to manually open the dust box 24, the dust box 32, and the water box 45 to empty the internal dust and accumulated water.
