[0002] At present, underground mining is mainly carried out by rock drilling and blasting. A large amount of dust will be generated during the tunneling process, among which rock drilling, blasting and rock loading are the main sources of dust. At the same time, the improvement of the mechanization degree in the tunneling process of dead-end tunnels and the use of high-power tunneling machines and other equipment have led to an increase in the dust concentration in the tunnel air. A large amount of fine, free minerals and rock particles generated during the tunneling process are called mine dust.

[0003] Ventilation and dust removal is one of the most effective measures to reduce the concentration of dust and toxic and harmful gases in the machine excavation working surface. At present, it is mainly realized based on three ideas: first, use specific ventilation technology for the dust source, use wind flow to remove dust from the tunnel or use dust control devices to limit high-concentration dust to a specific area; second, use the first dust removal fan to extract dust from the dust source in time; third, use high-pressure spray to make the dust adhere to the fog particles and force it to settle.

[0035] The invention provides an underground mine patrol-type air purification device.

[0036] like Figures 1 to 3 The underground mine patrol air purification device shown in the figure includes a controller, a first camera 15, a mover 7, a cylinder 1, a first fan 17, an atomizing mechanism 2 and a cylinder 1 arranged on the mover 7, wherein the two openings of the cylinder 1 along the axial direction respectively form an air inlet 11 and an air outlet 12; the filtering mechanism 3, the atomizing mechanism 2 and the first fan 17 are all arranged in the cylinder 1, the first fan 17 is arranged close to the air outlet 12, and the filtering mechanism 3 is arranged on the side of the first fan 17 away from the air outlet 12; the first fan 17 is used to drive the external air to pass through the air inlet 11, the filtering mechanism 3 and Air outlet 12; the atomizing mechanism 2 is connected to the filtering mechanism 3, and the atomizing mechanism 2 is used to input atomized water vapor into the filtering mechanism 3; a first camera 15 is arranged on the side of the cylinder 1 away from the movable device 7, and a controller is electrically connected to the first camera 15, the movable device 7, the atomizing mechanism 2 and the first fan 17 respectively, and the controller is used to control the movable device 7 to move along a preset route so that the first camera 15 can obtain a real-time image; the controller is used to determine a dust removal area according to the real-time image, and control the movable device 7 to enter the dust removal area so that the first fan 17 can perform dust removal operations on the dust removal area through the filtering mechanism 3 and the atomizing mechanism 2.

[0037] The mover 7 patrols according to a preset route, and the first camera 15 obtains real-time images during patrolling. The controller determines the dust removal area in the preset route based on the real-time images, and starts the first fan 17 and the atomizing mechanism 2 in the dust removal area, so that the air in the dust removal area contacts the atomized water vapor sprayed by the atomizing mechanism 2 when passing through the filtering mechanism 3, thereby quickly reducing the dust concentration in the dust removal area.

[0038] Specifically, the controller is used to obtain a standard image, and based on the standard image and the real-time image, determine whether there is a blurred area in the real-time image. When there is no blurred area in the real-time image, the controller controls the mover 7 to patrol along a preset route; when there is a blurred area in the real-time image, determine whether the number of blurred areas is greater than or equal to the number of jobs. When the number of blurred areas is greater than or equal to the number of jobs, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the number of blurred areas is less than the number of jobs, the step of the controller controlling the mover 7 to patrol along the preset route is executed.

[0039] Specifically, the standard image is an image obtained after multiple dust removals using an air purification device under the same photographing parameters.

[0040] Among them, when the dust removal is performed for the nth time and the color protection degree difference between the pixels of the image taken after the nth dust removal and the (n-1)th dust removal is lower than a preset difference, the image taken after the nth dust removal is used as the standard image.

[0041] Specifically, the controller is used to obtain a preset pixel standard, determine the pixel abnormal area according to the pixel standard and the real-time image; and determine the blurred area according to the pixel abnormal area and the standard image. The pixel standard is a pixel block of a preset color greater than or equal to a preset area in the real-time image, such as a yellow pixel block and a gray pixel block. The pixel abnormal area is determined based on the yellow pixel block or gray pixel block greater than or equal to the preset area in the real-time image, and then the pixel abnormal area is compared with the corresponding area in the standard image, eliminating interference items, and determining the abnormal area with high concentration of dust, so as to perform dust removal on the abnormal area.

[0042] Specifically, when the number of fuzzy areas is less than the number of operations, it is determined whether the sum of the areas of the fuzzy areas is greater than a preset area. When the sum of the areas of the fuzzy areas is greater than or equal to the preset area, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the sum of the areas of the fuzzy areas is less than the preset area, the controller controls the mover 7 to patrol along the preset route.

[0043] Specifically, when the number of blurred areas is less than the number of jobs, it is determined whether the color saturation of any blurred area is greater than a preset value. When the color saturation of any blurred area is greater than or equal to the preset value, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the color saturation of each blurred area is less than the preset value, the controller controls the mover 7 to patrol along the preset route.

[0044] According to the number of fuzzy areas (i.e. the number of dust points), the area of ​​fuzzy areas (i.e. the size of dust areas) and the color saturation of fuzzy areas (i.e. the concentration of dust), multi-directional dust removal is achieved to ensure timely dust removal and the effectiveness of dust removal.
