Description

Technical Field

[0001] This utility model relates to the technical field of wall-climbing inspection, and in particular to a wall-climbing inspection robot for boiler water-cooled walls. Background Technology

[0002] With the rapid development of industries such as thermal power generation and chemical industry, boiler water-cooled walls, as core pressure-bearing components, are directly related to the operating efficiency and lifespan of equipment due to their safety and reliability. Because they are exposed to high temperature, corrosive gases and high dust environment for a long time, complex deposits are easily formed on the surface of water-cooled walls. Traditional manual inspection has problems of low efficiency and high risk. Wall-climbing robots have gradually become the mainstream solution for non-destructive testing.

[0003] However, in practical applications, robot movement and detection accuracy face the following severe challenges: when the robot's movement mechanism (tracks or magnetic wheels) comes into contact with the wall, mechanical scraping and vibration can cause surface deposits to fall off, forming suspended dust. This dust can affect optical inspection equipment. Furthermore, during the inspection and cleaning process, blowing air to clean the dust can easily cause secondary dust, further aggravating the dust concentration in the air and adversely affecting subsequent work. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a wall-climbing inspection robot for boiler water-cooled walls. The robot guides the air entering the protective cover through a guide plate, forming a centrifugal force field and a low-pressure vortex core, which efficiently separates and blocks dust. At the same time, combined with atomized water spraying technology, it significantly improves the clarity of the images and the accuracy of the inspection.

[0006] To achieve the above objectives, this utility model proposes a wall-climbing inspection robot for boiler water-cooled walls, comprising a main body, a camera, and a protective assembly. The camera is mounted on the main body; the protective assembly includes a filter box mounted on the main body; a blower is mounted on the filter box, with the output end of the blower located inside the filter box; a backflow pipe is mounted on the filter box; a protective cover is mounted on the camera's imaging end; a blower housing is installed inside the protective cover; and multiple blower holes are provided on the blower housing.

[0007] In addition, the wall-climbing inspection robot for boiler water-cooled walls proposed in the above application may also have the following additional technical features:

[0008] Specifically, one end of the backflow pipe is connected to the protective cover, and the blower is equipped with a one-way valve at one end of the filter box.

[0009] Specifically, the protective cover is equipped with multiple guide plates, each guide plate and a multiple air blowing hole are corresponding one-to-one, and the multiple guide plates are inclined.

[0010] Specifically, the protective cover is equipped with a water supply pipe, and multiple atomizing nozzles are installed inside the water supply pipe.

[0011] Specifically, a water supply component is installed inside the main body, and the water supply component is connected to the water supply pipe through a connecting pipe.

[0012] This utility model discloses a wall-climbing inspection robot for boiler water-cooled walls. The robot guides the air entering the protective cover through a guide plate, so that the centrifugal force field and low-pressure vortex core formed by the air inside the protective cover can efficiently separate and block dust. At the same time, it can blow away the dust on the camera's imaging end, reducing the impact of dust on the camera. During the blowing, the robot uses mist to mix with the dust to achieve a dust reduction effect, avoid secondary dust generation, improve the clarity of the camera's image, and thus improve the accuracy of the inspection.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The following description, in conjunction with the accompanying drawings, describes a wall-climbing inspection robot for boiler water-cooled walls according to an embodiment of the present invention.

[0021] Figures 1-3 This is a structural schematic diagram of a wall-climbing inspection robot for boiler water-cooled walls according to an embodiment of the present invention.

[0022] like Figure 2 As shown, the boiler water-cooled wall climbing inspection robot of this utility model embodiment includes a main body 10, a camera 20 and a protective component 30, wherein the camera 20 is disposed on the main body 10; the protective component 30 includes a filter box 301 installed on the main body 10.

[0023] It should be noted that the filter box 301 is filled with two-thirds water.

[0024] A blower 302 is installed on the filter box 301, and the output end of the blower 302 is located inside the filter box 301; a backflow pipe 303 is installed on the filter box 301.

[0025] It should be noted that the backflow pipe 303 is connected to the suspension component via a flexible hose, allowing air from the filter box 301 to enter the backflow pipe 303 through the flexible hose, thus directly preventing water from flowing in. At the same time, the blower end of the blower 302 is connected to the counterweight via a flexible hose. Under the action of the counterweight, the flexible hose remains submerged in water regardless of the direction the filter box 301 is tilted, and the air blown out by the blower 302 will also enter the water. In addition, the exhaust end of the blower 302 is equipped with a filter screen, which can filter dust in the extracted air.

[0026] The camera 20 is equipped with a protective cover 304 at its shooting end; a blower shell 305 is installed inside the protective cover 304; and a plurality of blower holes 306 are provided on the blower shell 305.

[0027] Specifically, such as Figure 2 As shown, one end of the backflow pipe 303 is connected to the protective cover 304, and the blower 302 is equipped with a one-way valve at one end of the filter box 301.

[0028] It should be noted that since the filter box 301 contains a certain amount of water, when the main body 10 is not in operation, the one-way valve can block the water in the filter box 301 to prevent the water in the filter box 301 from entering the blower 302.

[0029] Specifically, such as Figure 3 As shown, the protective cover 304 is equipped with multiple guide plates 307, and the multiple guide plates 307 correspond one-to-one with multiple air holes 306, and the multiple guide plates 307 are inclined.

[0030] Specifically, such as Figure 3 As shown, a water supply pipe 308 is provided on the protective cover 304, and multiple atomizing nozzles 309 are installed on the inner side of the water supply pipe 308.

[0031] Specifically, during the movement of the main body 10, friction will occur between the main body 10 and the boiler water-cooled wall. This friction will cause dust on the boiler water-cooled wall to fall off. The fallen dust will then scatter around the boiler water-cooled wall and adhere to the camera 20, affecting the normal operation of the camera 20.

[0032] While the main body 10 moves, the blower 302 is controlled to operate, drawing in outside air into the filter box 301. The water in the filter box 301 then reduces dust in the air. The air then enters the blower housing 305 through the backflow pipe 303 and is discharged through multiple blow holes 306. The discharged air increases the air pressure inside the protective cover 304, preventing outside floating dust from entering and achieving the purpose of dust blocking. At the same time, the guide plate 307 guides the air, causing it to rotate. The centrifugal force field and low-pressure vortex core formed by the rotating air inside the protective cover 304 can efficiently separate and block dust. Simultaneously, the water supply pipe 308 is opened, supplying water to the atomizing nozzle 309. When the air passes through the atomizing nozzle 309, it combines with the mist to reduce dust.

[0033] Specifically, such as Figure 1 As shown, a water supply component is installed inside the main body 10, and the water supply component is connected to the water supply pipe 308 through a connecting pipe.

[0034] It should be noted that the water supply unit uses a water pump to supply water to the water supply pipe 308, and at the same time the water pump will draw water from the container, which is installed inside the main body 10, or other water supply methods can be used to supply water to the water pump.

[0035] In summary, the wall-climbing inspection robot for boiler water-cooled walls in this embodiment of the present invention guides the air entering the protective cover 304 through the guide plate 307. The centrifugal force field and low-pressure vortex core formed by the air in the protective cover 304 can efficiently separate and block dust. At the same time, it can blow away the dust on the camera end of the camera 20, reducing the impact of dust on the camera. When blowing air, the mist mixes with the dust to achieve the effect of dust reduction, avoid secondary dust generation, improve the image clarity of the camera 20, and thus improve the accuracy of the inspection.
