[0001] The utility model relates to the technical field of wind power equipment foundation concrete maintenance, in particular to an intelligent maintenance and heat preservation device for wind power equipment foundation concrete. Background Art

[0002] With the continuous development of my country's wind power industry, the volume of wind turbine foundation concrete has also been expanding, making its maintenance more difficult. In the prior art, the foundation concrete is laid with insulation pipes on the surface to reduce the temperature difference between the inside and outside, so that the temperature difference between the inside and outside is within a certain range, thereby avoiding cracks on the surface of the foundation concrete.

[0003] However, with the increase of curing time, the curing temperature of the foundation concrete surface gradually increases, which reduces the temperature difference between the foundation concrete surface and the interior, resulting in the temperature difference not being within the specified range, and further causing cracks on the foundation concrete surface. Therefore, during the foundation concrete surface curing process, its surface curing temperature needs to be adjusted. At present, the foundation concrete surface curing temperature is mostly adjusted by adjusting the water temperature in the insulation pipe. Due to the large volume of foundation concrete and its high water consumption, it takes a long time to adjust the water temperature, resulting in untimely adjustment of the foundation concrete surface curing temperature.

[0025] Example 1

[0026] With the continuous development of my country's wind power industry, the volume of the wind turbine foundation concrete 1 is also constantly expanding. The wind turbine foundation concrete 1 is a truncated cone structure with a larger overall lower part and a larger span from the peripheral support structure to the center upper part. Figure 1 As shown, the inclined annular surface of the foundation concrete 1 needs to be cured.

[0027] An intelligent maintenance and insulation device for wind power equipment foundation concrete 1 includes an insulation pipe laid on the surface of the foundation concrete 1. The insulation pipe is a hose and is fixedly connected to the surface of the foundation concrete 1 through a fixing frame. In this embodiment, the insulation pipe is arranged around the center of the foundation concrete 1. At the same time, a plurality of fixing clamps for fixing the insulation pipe are installed on the fixing frame. The fixing clamps slide on the fixing frame and can be fixed, that is, the distance between two adjacent fixing clamps on the fixing frame can be adjusted, and the insulation spacing of the insulation pipe can be further adjusted. Two coaxial annular slide rails 2 are arranged above the surface of the foundation concrete 1. The two annular slide rails 2 are radially spaced apart along the surface of the foundation concrete 1. Each annular slide rail 2 is fixedly connected to the surface of the foundation concrete 1 through a plurality of support legs 202. The plurality of support legs 202 are evenly spaced apart circumferentially along the corresponding annular slide rail 2, such as Figure 2 As shown, the support leg 202 is vertically arranged, and the top of the support leg 202 is fixedly connected to the bottom of the corresponding annular slide rail 2, and the connection between the two is bolted or welded; the bottom of the support leg 202 is fixedly connected to the surface of the foundation concrete 1, and the connection between the two is bolted or integrally connected. The support leg 202 is a concrete structure or steel. When the support leg 202 is a concrete structure, when pouring the foundation concrete 1, multiple support legs 202 are poured on its surface, the bottom end of the support leg 202 is integrally connected to the foundation concrete 1, and the top end of the support leg 202 is bolted to the annular slide rail 2; when the support leg 202 is steel, the connection between the top end of the support leg 202 and the annular slide rail 2 is welded, and the connection between the bottom end of the support leg 202 and the foundation concrete 1 is bolted. In this embodiment, the support leg 202 is steel, and the connection between the top end of the support leg 202 and the annular slide rail 2 is welded, and the connection between the bottom end of the support leg 202 and the foundation concrete 1 is bolted. In this embodiment, the number of the supporting legs 202 is 8 and they are evenly divided into two groups, that is, one annular slide rail 2 is connected to the foundation concrete 1 through four supporting legs 202 .

[0028] like Figure 4As shown, a plurality of fixed covers 4 distributed along the circumference of the annular slide rail 2 are fixedly connected to the bottom thereof, and the plurality of fixed covers 4 are evenly spaced along the circumference of the annular slide rail 2.

In the present embodiment, the number of the fixed covers 4 is 7 and they are fan-shaped structures, and there is a window area between two adjacent fixed covers 4. A movable cover 5 that can slide circumferentially along the annular slide rail 2 is provided on one side of the window area. The movable cover 5 is located above the annular slide rail 2 and can slide along the annular slide rail 2. During the sliding process of the movable cover 5, it can cooperate with the fixed cover 4 to cover all the insulation pipes or be staggered with the fixed cover 4 to form a temperature regulating gap 3. In the initial stage of maintenance, the movable cover 5 slides to the top of the window area and closes the window area, so that the movable cover 5 and the fixed cover 4 are spliced ​​to form a circular cover to cover all the insulation pipes to avoid heat loss of the insulation pipes; as shown Figure 5 As shown, as the curing time increases, the temperature of the surface of the foundation concrete 1 needs to be adjusted, so the movable cover 5 is slid so that a part of the movable cover 5 is located above the fixed cover 4 and the other part is located above the empty window area, and then the movable cover 5 and the fixed cover 4 are staggered to expose a part of the empty window area to form a temperature adjustment gap 3, that is, the temperature of the foundation concrete 1 can be adjusted in time; in this embodiment, the temperature of the surface of the foundation concrete 1 can be adjusted by adjusting the width of the temperature adjustment gap 3, that is, the temperature of the surface of the foundation concrete 1 can be controlled more accurately.

[0029] The fixed cover 4 , the movable cover 5 and the annular slide rail 2 are made of light materials, which facilitates the movement of the movable cover 5 .
