Description

Technical Field

[0001] The invention belongs to the technical field of coal mine ventilation, and in particular relates to an underground ventilation, dust reduction and temperature reduction fan device. Background Art

[0002] Coal mines are generally divided into underground coal mines and open-pit coal mines. The vast majority of coal mines in my country are underground coal mines, which require coal mining by digging tunnels underground. During the coal mining process, the mines need to be ventilated and dust and temperature reduced to create a good and safe working environment.

[0003] When it is necessary to ventilate an underground coal mine, the prior art generally uses a ventilator and a ventilation pipe to ventilate the underground coal mine. In an underground coal mine, the air usually contains dust, fiber and other particulate matter. When these particles flow rapidly on the surface of the ventilator blades, they will rub against the surface of the blades and generate static electricity. Since there is methane gas in the underground coal mine, when the static electricity generated by the fan blades is discharged, it may cause sparks, and then cause an explosion, causing a serious safety accident. Therefore, before the ventilator is put into use, an anti-static coating is usually applied to the surface of the fan blades to prevent the fan blades from generating static electricity. However, when the ventilator is used to ventilate the underground coal mine, due to the complex environment of the underground coal mine, with the use of the fan blades, during the high-speed rotation of the fan blades, when they come into contact with flying stones or harder particles, the anti-static coating on the surface of the fan blades will be damaged, causing the original material of the fan blades to be exposed. At this time, during the subsequent use of the fan blades, it is easy to generate static electricity at the damaged part, causing safety hazards, which greatly reduces the safety and reliability of underground ventilation.

[0022] The operating principle of the present invention is now described as follows:In the present invention, when it is necessary to ventilate the underground coal mine, the ventilator 6 is controlled to start, and the outside air is transported into the underground coal mine through the ventilation pipe 3 to complete the ventilation of the underground coal mine. During the operation of the ventilator 6, the first spray gun 115 is controlled to start, and the refrigerated water in the water storage refrigeration box 7 is transported to the first spray gun 115 through the output pipe 114, the connecting pipe 112 and the first spring hose 116. The first spray gun 115 is used to spray the blades of the ventilator 6. After the refrigerated water contacts the blades of the ventilator 6, it will form water mist driven by the wind pressure, which has a dual effect of cooling and dust removal on the tunnels in the underground coal mine. In this process, the second motor 113 is controlled to drive the connecting pipe 112 to rotate back and forth, and drive the first spray gun 115 to rotate back and forth. The water sprayed from the first spray gun 115 can be sprayed evenly onto the surface of the fan 6 blades, and the sprayed water can also be used to clean the surface of the fan 6 blades, so that the surface of the fan 6 blades does not adhere to the dust in the underground coal mine, which is convenient for the subsequent use of the ultrasonic detector 1018 to detect whether the anti-static coating on the surface of the fan 6 blades is damaged. After the fan 6 is used to ventilate the underground coal mine, when the fan 6 is turned off, the third motor 103 is controlled to start, driving the first round rod 102 to rotate 90 degrees and then stop. At this time, the side wall of the first slide plate 106 corresponds to the fan 6 blades, and then the first electric slide rail 105 is controlled to start, driving the first slide plate 106 to move, so that the third U plate 107 moves to one of the blades of the fan 6. The fourth motor 109 is then controlled to start, driving the second round rod 108 to rotate 90 degrees and then stop, so that one end of the first electric telescopic rod 1010 is located on one side of the fan 6 blade, and then the fifth motor 1013 and the sixth motor 1016 are controlled to start, respectively driving the third round rod 1012 and the fourth round rod 1015 to rotate, so as to adjust the angle between the mounting rod 1017 and the ultrasonic detector 1018, so that the detection end of the ultrasonic detector 1018 matches the inclination angle of the corresponding fan 6 blade surface, so that when the detection end of the ultrasonic detector 1018 detects the fan 6 blade surface, the detection end of the ultrasonic detector 1018 is perpendicular to the corresponding fan 6 blade surface, and then the first electric telescopic rod 1010 is controlled to start, driving the third round rod 1012 and the fourth round rod 1015 to rotate respectively, so as to adjust the angle between the mounting rod 1017 and the ultrasonic detector 1018, so that the detection end of the ultrasonic detector 1018 is perpendicular to the corresponding fan 6 blade surface when detecting the fan 6 blade surface, and then the first electric telescopic rod 1010 is controlled to start, driving the third round rod 1012 and the fourth round rod 1015 to rotate respectively, and then adjusting ..., and then the first electric telescopic rod 101 Start, drive the ultrasonic detector 1018 to move toward the fan 6 blades, then control the ultrasonic detector 1018 to start, and detect whether the antistatic coating on the surface of the fan 6 blades is damaged. Then, by controlling the first motor 92 to start, drive the second gear 93 to rotate, so that the corresponding first gear 91 rotates, thereby driving the rotating ring 8 to rotate, so that the ultrasonic detector 1018 adjusts its position. In this process, control the first electric slide rail 105 to start, drive the first slide plate 106 to move, and use the rotation of the first electric slide rail 105 and the rotating ring 8 to continuously adjust the position of the ultrasonic detector 1018, so as to use the ultrasonic detector 1018 to detect whether the antistatic coating on the surface of the fan 6 blades is damaged. In this process,By controlling the fifth motor 1013 and the sixth motor 1016 to start, the detection end of the ultrasonic detector 1018 can always be perpendicular to the surface of the fan 6 blade to be detected, so that the ultrasonic detector 1018 can be used to detect the antistatic coating on the surface of the fan 6 blade. When it is detected that the antistatic coating on the surface of the fan 6 blade is damaged, the two seventh motors 1022 are controlled to start, driving the rotating tube 1021 to rotate, so that the water outlet end of the second spray gun 1023 corresponds to the position where the antistatic coating on the surface of the fan 6 blade is damaged. , and then the second spray gun 1023 is controlled to start, and the antistatic solution in the liquid storage tank 1019 is sprayed to the damaged position of the antistatic coating on the surface of the ventilator 6 blades through the second spring hose 1024, and the damaged position of the antistatic coating on the surface of the ventilator 6 blades is repaired to avoid static electricity from being generated at the damaged position of the ventilator 6 blades during subsequent use, which may cause safety hazards. When it is necessary to ventilate the underground coal mine, the refrigerated water in the water storage refrigeration box 7 can be transported to the first spray gun 115, and the first spray gun 115 can be used to spray the ventilator 6 blades. The blades of the fan 6, after being cooled, will form water mist driven by wind pressure after contacting the blades of the fan 6, which has a dual effect of cooling and dust removal in the tunnels in the underground coal mine. The sprayed water can also be used to clean the surface of the fan 6 blades, so that the surface of the fan 6 blades does not adhere to the dust in the underground coal mine, which is convenient for the subsequent use of the ultrasonic detector 1018 to detect whether the anti-static coating on the surface of the fan 6 blades is damaged, and the detection end of the ultrasonic detector 1018 can always be perpendicular to the surface of the fan 6 blades being detected, which is convenient for the use of the ultrasonic detector 1018 to detect the anti-static coating on the surface of the fan 6 blades. When the anti-static coating on the surface of the fan 6 blades is detected to be damaged, the anti-static solution in the liquid storage tank 1019 is sprayed to the damaged position of the anti-static coating on the surface of the fan 6 blades, and the damaged position of the anti-static coating on the surface of the fan 6 blades is repaired, so as to avoid the fan 6 blades from generating static electricity at the damaged part during subsequent use, which may cause safety hazards, and greatly improve the safety and reliability of the device when ventilating underground.
