Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mining dust removal equipment, specifically relating to a defogging and dust removal device for mining explosion-proof cameras. Background Technology
[0002] To optimize the mining process and promote the informatization of the mining industry, an AI-powered video intelligent auxiliary supervision and monitoring system is being built. High-definition cameras and intelligent image analysis equipment are installed at key points on the surface and underground in coal mines and key non-coal mines to monitor the production and safety status of coal mines and key non-coal mines in real time. The system analyzes and judges whether there are illegal production operations such as operating under the guise of shutdown or exceeding the staffing quota, thereby improving operational safety and monitoring geological disasters after mining, facilitating early warning and alerts.
[0003] For information collection, explosion-proof mining cameras are used at the main conveyor belt head, the entrance boarding point, and the bottom yard area. However, due to environmental factors, fog and dust easily adhere to the cameras during use, resulting in unclear images. This requires regular manual cleaning, which is time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of this invention is to provide a defogging and dust removal device for explosion-proof cameras used in mines, which can effectively and quickly remove fog and dust generated by underground cameras, preventing fog and dust from adhering to the camera lens and causing unclear images, thus freeing up manual labor.
[0005] The technical solution adopted by this utility model is a defogging and dust removal device for a mine explosion-proof camera, which includes an air jet hole and a water jet hole set inside the annular sleeve. The annular sleeve is fitted onto the end of the camera lens of the mine explosion-proof camera. The air jet hole and the water jet hole are staggered around the camera lens and the spray direction is towards the camera lens surface. The air jet hole and the water jet hole are respectively connected to an air pump and a water pump through pipes.
[0006] Preferably, the jet nozzle and water nozzle are connected to the gas chamber and the water mixing chamber, respectively, and the gas chamber and the water mixing chamber are connected to the air pump and the water pump, respectively, through pipes.
[0007] Preferably, the camera lens, gas chamber and mixing chamber of the above-mentioned camera are arranged inside the annular sleeve, and a drain hole is provided at the bottom of the annular sleeve. The drain hole is connected to the drain channel through a thin tube.
[0008] The beneficial effects of this utility model are as follows: the defogging and dust removal device uses staggered air jet holes and water jet holes, which can effectively and quickly remove fog and dust generated by the underground camera, preventing fog and dust from adhering to the camera lens and causing unclear images, thus reducing the labor intensity of workers; the ring sleeve structure makes installation convenient and quick, and the inclined high-pressure air jet and water jet can effectively remove dust and dirt from the mirror surface; the use of a gas chamber and a water mixing chamber can quickly and simultaneously spray water or air from multiple holes; and a drainage hole is set at the bottom to drain the generated water in a timely manner, reducing dripping onto the ground or affecting the operation of the equipment. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of a defogging and dust removal device used in explosion-proof cameras for mining applications. Detailed Implementation
[0010] The present invention will now be further described in conjunction with the accompanying drawings to enable those skilled in the art to better understand it.
[0011] Please see Figure 1 The defogging and dust removal device for a mine explosion-proof camera includes air jet holes 101 and water jet holes 102 located inside an annular sleeve 10. The annular sleeve 10 is fitted onto the end of the camera lens of the mine explosion-proof camera 103. The air jet holes 101 and water jet holes 102 are staggered around the camera lens of the camera 103, with the jet direction facing the camera lens surface. The air jet holes 101 and water jet holes 102 are respectively connected to an air pump 106 and a water pump 107 through pipes. The defogging and dust removal device uses staggered air jet holes 101 and water jet holes 102, which can effectively and quickly remove fog and dust generated by the underground camera, avoiding fog and dust adhering to the camera lens and causing unclear images, thus reducing the labor intensity of workers. The annular sleeve structure makes installation convenient and quick, and the tilted high-pressure air jet and water jet can effectively remove dust and dirt from the lens surface.
[0012] To enable multiple holes to spray water or air simultaneously and quickly, the air jet hole 101 and the water jet hole 102 are connected to the gas chamber 104 and the water mixing chamber 105, respectively. The gas chamber 104 and the water mixing chamber 105 are connected to the air pump 106 and the water pump 107, respectively, through pipes. The camera lens of the camera 103, the gas chamber 104 and the water mixing chamber 105 are set inside the annular sleeve 10, and the bottom of the annular sleeve 10 is provided with a drain hole 108. The drain hole 108 is connected to the drainage channel through a thin pipe. The drain hole 108 at the bottom can drain the generated water in time, reducing dripping onto the ground or affecting the operation of the equipment.
