Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] As Figures 1 to 5 shown, a patrol robot for mine tunnel patrol includes a robot body 1 and a camera assembly 2 connected to the bottom of the robot body 1. The outer wall of the control board in the middle of the camera assembly 2 is connected with an air curtain shielding assembly 3. The air curtain shielding assembly 3 includes a fan 301. The fan 301 is located at the lower end of the middle control board of the camera assembly 2. The top of the air outlet of the fan 301 is connected with an air intake pipe 302. The air intake pipe 302 is located on the outer wall of the middle control board of the camera assembly 2. Connecting air ducts 303 are provided on both sides of the outer wall of the air intake pipe 302. The connecting air ducts 303 are located on the sides of the two lenses of the camera assembly 2.

[0024] As Figure 1 shown, the patrol robot for mine tunnel patrol in the present invention is similar in structure to the existing suspended mine explosion-proof patrol robot. For example, a suspended mine explosion-proof patrol robot disclosed in the patent of CN215881621U. The main improvement point of the present invention is that the lens of the camera will not be polluted by dust during the patrol process, ensuring the patrol effect. As Figures 1 to 5 shown, when the patrol robot for mine tunnel patrol in the present invention is in use, when the camera assembly 2 is patrolling in the mine tunnel, the lens will be covered with dust. The fan 301 is started. The fan 301 blows the air flow into the connecting air ducts 303 on both sides in the air intake pipe 302, so that the air flow blows against the lens of the camera assembly 2. The high-speed air flow of the fan 301 can form an air curtain for the lens, thereby shielding dust and preventing dust from adhering to the outer surface of the lens. By using the connecting air ducts 303, the wind speed can be further increased.

[0025] The air inlet of the fan 301 can be a high-mesh dust-proof net, thereby extending the service life of the fan 301 and further prolonging the service life of the fan 301.

[0026] Here, the robot issues an instruction to start the fan 301, which belongs to the existing mature technology, and the fan 301 is also a common product model on the existing market, so no more details will be described here.

[0027] As shown Figures 1 to 5 in the figure, extension plates 5 are fixedly connected to both sides of the air intake duct 302. An extension air duct 51 is provided through the extension plates 5. The extension air duct 51 is communicated with the air outlet of the fan 301 through a connecting air duct 303 and the air intake duct 302. The extension air duct 51 is located at the side of the lens of the camera assembly 2.

[0028] Specifically, in order to make the air flow faster and the formed air curtain effect better, by using the extension plates 5 and the extension air duct 51, the air outlet can be made to face the side of the lens, thereby increasing the flow rate and further improving the effect of the air curtain in shielding dust from the lens.

[0029] As shown Figures 1 to 5 in the figure, a horizontal frame 52 is fixedly connected to one end of the extension plate 5 away from the air intake duct 302. The setting of the horizontal frame 52 inside can facilitate the air outlet of the extension plate 5 not to face the lens completely. The horizontal frame 52 can make the air flow blow along the lens, maximizing the shielding effect formed by the air curtain.

[0030] As shown Figures 1 to 5 in the figure, an air outlet connection block 304 is fixedly connected to the top of the air outlet of the fan 301. An insertion ring 7 is fixedly connected to the top of the air outlet connection block 304. The insertion ring 7 is inserted into the inner wall of the air intake duct 302.

[0031] Specifically, by using the insertion ring 7 and inserting the insertion ring 7 into the air intake duct 302, it can facilitate the disassembly between the bottom of the air intake duct 302 and the air outlet connection block 304, which is convenient for the later cleaning of the air intake duct 302.

[0032] As shown Figures 1 to 5 in the figure, a sealing gasket 8 is sleeved on the top surface of the air outlet connection block 304. The setting of the sealing gasket 8 can seal between the bottom of the air outlet connection block 304 and the bottom of the air intake duct 302 to prevent air leakage.

[0033] As shown Figures 1 to 5 in the figure, an installation bracket 4 is bolted to the bottom of the middle control board of the camera assembly 2. The installation bracket 4 is U-shaped. The fan 301 is located inside the installation bracket 4 and is fixedly installed by bolts. By using the installation bracket 4, it is convenient to install and disassemble the fan 301.

[0034] As shown Figures 1 to 5 in the figure, a mounting plate is fixedly connected to the top of the air intake duct 302. A screw 6 is threadedly connected inside the mounting plate. The screw 6 passes through the mounting plate and is threadedly connected to the outer shell of the camera assembly 2. By using the screw 6 and the mounting plate, the air intake duct 302 can be disassembled.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
