It aims to improve the problem that the installation of the paint spray head in the existing magnetic adsorption crawling robot for repairing the paint surface of the outer wall of wind turbine towers is extremely cumbersome. During installation, it is necessary to use a variety of additional tools such as screwdrivers and wrenches to perform a large number of screw-tightening and nut-tightening operations. Moreover, the installation process requires extremely high alignment accuracy between the paint spray head and the mounting block, which requires repeated adjustments. Even a slight deviation will affect the repair effect and seriously reduce work efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a magnetic adsorption crawling robot for repairing the paint surface of the outer wall of a wind turbine tower, comprising a crawling robot body, a swing rod installed on the top of the crawling robot body, an installation block fixedly connected to the outside of the swing rod, a fixing component inside the installation block, a T-shaped groove opened inside the installation block, a T-shaped block slidably connected to the inner wall of the T-shaped groove, a paint spray head fixedly connected to the outside of the T-shaped block, two sliding grooves opened inside the installation block, two connecting frames fixedly connected to the outside of the swing rod, and a heating component provided on the outside of the connecting frames;

[0007] The fixing component includes two baffles, the outer side of which is slidably connected to the inner wall of the slide groove. A spring is fixedly connected to one side of the baffle, and a plug block is fixedly connected to the other side of the baffle. A handle is fixedly connected to the outer side of the baffle.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the handle connected to the outside of the baffle, the handle drives the baffle to slide in the groove, which in turn compresses the first spring, and the plug block slides into the mounting block. The T-shaped block of the paint spray head is aligned with the T-shaped groove and slid in. When the paint spray head is adjusted to the appropriate position, the handle is released. Under the elastic force of the first spring, the baffle drives the plug block to be inserted into the T-shaped block again, realizing the convenient installation of the paint spray head on the mounting block. There is no need to use additional tools for complicated disassembly and installation operations, nor is there a complicated alignment and adjustment process.

[0024] 2. In this utility model, after the fan is started, air is blown downwards toward the heating wire. The air is rapidly heated as it passes through the heating wire. The heated air is then blown evenly onto the area on the outer wall of the tower that has just been painted through multiple air outlets fixed at the top of the heating box. This concentrated heating of the paint surface greatly accelerates the drying speed of the paint surface and effectively improves the efficiency and quality of the overall repair work.

[0035] Specifically, the crawling robot body 1 includes a main structure, a magnetic adsorption system, a movement mechanism, a power and control system, and a painted swing assembly. The painted swing assembly of the crawling robot body comprises a power source motor, transmission components, swing rods, and angle control elements. Structurally, the frame is made of high-strength, lightweight materials and has an overall arc-shaped fit to adapt to the curved surface of the tower. The magnetic adsorption system includes multiple composite magnetic adsorption units combining permanent magnets and electromagnets distributed at the bottom of the main body. The movement mechanism is installed at the bottom of the main body and consists of moving wheels, magnetic blocks, a drive motor, a planetary reducer, and guide wheels. In the power and control system, power is provided by a high-performance rechargeable battery pack, and the control system adopts a distributed control architecture, including a main controller and sub-controllers. The device is equipped with a controller and connects to various sensors such as vision sensors and gyroscope sensors. A swing arm 2 is mounted on the top of the main body, used to connect to the mounting block 3 and swing flexibly. The mounting block 3 is used to set the fixing components and create a T-slot 4. The inner wall of the T-slot 4 is used for sliding connection with the T-block 5. The T-block 5 is used to connect the paint spray head 6. The paint spray head 6 is used for paint repair spraying operations. Two sliding grooves 7 are used for sliding the baffle 9. A connecting frame 13 is fixed to the outside of the swing arm 2 and is used to install the heating component. The heating component is used to heat the spraying area. The baffle 9 is used to control the position of the plug-in block 10. A spring 8 is used to provide elasticity to reset the baffle 9. The plug-in block 10 is used to fix the T-block 5 and thus fix the paint spray head 6. A handle 11 is used to facilitate the operator to pull the baffle 9.

[0036] Reference Figure 1 - Figure 3 The heating assembly includes a heating box 14, which is fixedly connected to the outside of the connecting frame 13. A fan 15 is installed on the upper side of the inner wall of the heating box 14, and multiple heating wires 16 are installed on the lower side of the inner wall of the heating box 14.

[0037] Specifically, the heating box 14 is fixed on the outside of the connecting frame 13 to accommodate the fan 15 and heating wires 16 and to serve as a carrier for generating and transporting hot air; the fan 15 is used to blow air downwards; multiple heating wires 16 are used to heat the air blown down by the fan 15, and the heated air is used to accelerate the drying of the paint on the outer wall of the wind turbine tower, thereby improving repair efficiency and quality.

[0038] Reference Figure 1 - Figure 3 The handle 11 is slidably connected to the inside of the mounting block 3 on the outside, the plug block 10 is plugged into the inside of the T-shaped block 5 on the outside, multiple air outlets 12 are fixedly connected to the top of the heating box 14, the fan 15 is set above the heating wire 16, the plug block 10 is slidably connected to the inside of the mounting block 3 on the outside, and the end of the spring 8 away from the baffle 9 is fixedly connected to the inner wall of the slide groove 7.

[0039] Specifically, the handle 11 is used by the operator to pull and move the baffle 9; the plug block 10 is used to fix the T-block 5 and thus fix the paint spray head 6; multiple air outlets 12 are used to blow the heated air evenly to the painting area on the outer wall of the wind turbine tower; the fan 15 is used to blow air to the heating wire 16 for heating; and the spring 8 is used to provide elasticity to reset the baffle 9, thereby driving the plug block 10 to move.

[0040] Working principle: When the operation begins, the main body of the crawling robot 1 uses its own magnetic adsorption properties to crawl smoothly along the outer wall of the wind turbine tower and accurately locate the specific area that needs to be repaired.

[0041] When the operator needs to fix the position of the spray nozzle 6, pull the handle 11 connected to the outside of the baffle 9. The handle 11 drives the baffle 9 to slide in the slide groove 7, which in turn compresses the spring 8. The plug block 10 slides into the mounting block 3, aligns the T-shaped block 5 of the spray nozzle 6 with the T-shaped groove 4 and slides it in. After the spray nozzle 6 is adjusted to the appropriate position, release the handle 11. Under the elastic force of the spring 8, the baffle 9 drives the plug block 10 to re-insert into the T-shaped block 5, thereby fixing the spray nozzle 6.

[0042] After the fan 15 is started, air is blown downwards toward the heating wire 16. The air is rapidly heated as it passes through the heating wire 16. The heated air is then blown evenly through multiple air outlets 12 fixed at the top of the heating box 14 toward the area on the outer wall of the tower that has just been painted, thus concentrating the heating of the paint surface and greatly accelerating the drying speed of the paint surface, effectively improving the efficiency and quality of the overall repair work.

[0043] Throughout the operation, the crawling robot body 1 continuously crawls along the outer wall of the tower, while the swing arm 2 swings flexibly according to the actual operation, driving the installation block 3 and related components to work together, ultimately completing the repair task of the paint surface on the outer wall of the wind turbine tower efficiently and with high quality.
