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

[0003] The purpose of the present invention is to provide a mine safety and environmental protection ventilation equipment to solve the problems raised in the background technology.

[0027] Usage method of the present invention:

[0028] In the initial state:

[0029] The first connecting rod 27 and the electric push rod 28 are both in a contracted state. The moving plate 18 is in contact with the fixed cylinder 17. The fixed cylinder 17 and the moving 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. The scraper 39 is at one end close to the torsion spring 37.

[0030] When the user needs to use this device, the user needs to move this device into the mine so that the fixing plate 13 adheres to one side of the mine tunnel. Then, the present invention can be started. The external gas enters the ventilation pipe 14 through the external pipeline. Then, under the action of the control terminal 12, the motor in the ventilation pipe 14 starts, driving the fan 36 to rotate, thus completing the ventilation in the mine. Under the action of the control terminal 12, the nozzle 44 starts, spraying out the water transported by the external pipeline, so that an appropriate amount of moisture adheres to the ground in the mine to reduce dust. After a certain period of time, when the moisture on the ground in the mine is about to evaporate, the control terminal 12 will drive the nozzle 44 to complete spraying again and again, thus controlling the humidity in the mine, reducing ground dust. When a transport vehicle passes through the mine or other reasons cause dust to be lifted, and when the dust concentration in the air reaches a certain level, it will be detected by the dust sensor 16. Then, the dust sensor 16 will be triggered, sending a signal to the control terminal 12. After receiving the signal emitted by the dust sensor 16, the motor in the ventilation pipe 14 will stop starting, the fan 36 will stop rotating, and the first motor 22 will start. After the first motor 22 starts, its motor shaft will drive the fixed cylinder 17 to rotate, driving the fixed cylinder 17 and the moving plate 18 to rotate towards the first screw rod 19 and the limiting rod 20 by nearly 90°, but there is still a certain slope as a whole. The end of the blocking film 33 close to the base 11 is at a lower position, making the fixed cylinder 17 parallel to the ground. Then, the second motor 21 will start under the action of the control terminal 12. After the second motor 21 starts, its motor shaft will drive the first screw rod 19 to rotate, causing the moving plate 18 to move away from the fixed cylinder 17, pulling out the blocking film 33, and the winding drum 41 rotates. Then, the fourth motor 26 and the electric push rod 28 will start under the action of the control terminal 12. After the fourth motor 26 starts, its motor shaft will drive the first connecting rod 27 and the second connecting rod 29 to rotate, and the electric push rod 28 starts to extend, driving the telescopic rod 31 to extend, moving the drainage cylinder 30 to the center of the mine tunnel. Then, the air pump 23 will start, sucking through the drainage cylinder 30, attracting the dust on both sides to move towards the drainage cylinder 30. Then, the control terminal 12 will start the nozzle 44 to spray, so that the dust quickly drops onto the blocking film 33 under the action of spraying. The dust sucked into the drainage cylinder 30 will enter the dust collection box 24 and be blocked by the filter screen, greatly accelerating the dust removal speed and controlling the humidity in the mine, thus preventing a high-humidity environment in the mine caused by spraying, which affects the physical health of the staff. Until a certain period of time later,When the dust sensor 16 detects that the dust concentration is low and has not reached the trigger value, the fourth motor 26, the electric push rod 28, and the second motor 21 will be started. After the electric push rod 28 is started, it will start to contract, thereby driving the drainage cylinder 30 and the second connecting rod 29 to reset. After the fourth motor 26 is started, it will start to rotate, thereby driving the first connecting rod 27, the second connecting rod 29, and the drainage cylinder 30 to reset. Then the second motor 21 will be started. After the second motor 21 is started, it will drive the moving plate 18 to reset. Since the blocking film 33 is closely attached to the side walls of the inlet and outlet on the fixed cylinder 17, dust and water droplets will be scraped off by the side walls of the inlet and outlet and will not enter the fixed cylinder 17, but will accumulate on the blocking film 33 between the fixed cylinder 17 and the moving plate 18. The torsion spring 37 resets and drives the reel 41 to rotate, thereby keeping the blocking film 33 always taut. When the blocking film 33 is wound up, when the water droplets on its upper part accumulate to a certain extent, under the action of gravity, they will preferentially fall into the dust collection box 32 and the water collection box 45 together with the dust on the blocking film 33 until the moving plate 18 is completely reset. At this time, the third motor 42 and the first motor 22 will be started. After the third motor 42 is started, its motor shaft will drive the second screw rod 38 to rotate, thereby driving the scraper 39 to move towards the first motor 22 direction, so as to scrape off water droplets and dust. After the first motor 22 is started, it will drive the fixed cylinder 17 and the moving plate 18 to reset. The water droplets and dust scraped off by the scraper 39 will fall into the inlet 43 under the action of gravity, and then fall into the dust collection box 32, thereby controlling the humidity inside the mine and avoiding excessive mud on the ground caused by spraying. Then the third motor 42 is started again under the action of the control terminal 12, thereby driving the scraper 39 to reset. Then the motor in the ventilation pipe 14 is started again under the action of the control terminal 12, so that the fan 36 rotates again, thereby ensuring the ventilation in the mine. After a certain period of time, the user needs to manually open the dust collection box 24, the dust collection box 32, and the water collection box 45 to empty the internal dust and accumulated water.
