[0002] At present, the foundations of most wind turbine generator sets in my country adopt reinforced concrete extended foundations, and the existing wind turbine foundations have a fixed and single structural form, often relying on tie bars and concrete pouring to form an integral structure. This structure is difficult to adapt to different geological conditions.

[0003] Wind turbines are most widely used in the northwest Gobi region, which is rich in wind resources. However, the wind turbine foundations made of reinforced concrete are often eroded by wind and sand, and the surface wear is severe. In addition, the northwest region has little precipitation and a dry climate, so the wind turbine concrete foundation is prone to cracking. Therefore, an anti-erosion device for the wind turbine concrete foundation is urgently needed to solve the above problems. Utility Model Content

The utility model has a reasonable structure and is easy to operate. It can not only strengthen the protection of the surface of the concrete foundation of the wind turbine and reduce wind and sand erosion and wear, but also can regularly moisten the surface of the concrete foundation to prevent the wall from drying out and cracking.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions: a wind turbine concrete foundation anti-erosion device, comprising a concrete foundation wall, a wall side, a circulation pipe, a mounting pipe, a protective component, a concrete layer, steel bars, a protective film, a fixing ring, a cross bar and a drip groove, wherein the concrete foundation wall is composed of a concrete layer and a protective film, the concrete layer is filled with a plurality of steel bars, and the steel bars extend to the left and right wall sides of the concrete foundation wall, the protective component is arranged on the circulation pipe, and the circulation pipe is arranged on the upper surface of the concrete foundation wall, and the circulation pipe is also provided at the left and right wall sides. An installation pipe is provided, and a plurality of drip grooves are opened on the bottom side of the circulation pipe. The fixed ring is assembled in the middle part of the circulation pipe, and a cross bar is provided between the left and right fixed rings. The protective assembly includes a water tank, a water outlet pipe, a hook, a water level observation meter, a slope pad, a timer and a water pump. Two water pumps are provided inside the water tank, and a timer is added between the two water pumps. The top of the water pump is connected to the water outlet pipe, and the water outlet pipe is also installed together with the circulation pipe. A hook is also provided on the top of the water tank and connected to the cross bar on the fixed ring. The water level observation meters are evenly distributed on both sides of the water tank surface.

[0006] Furthermore, the timer is internally connected to a water pump, and the timer uniformly controls the water pumps on the left and right sides to work simultaneously.

[0007] Furthermore, slope pads inclined toward the middle are added on both left and right sides of the water tank.

[0008] Furthermore, the water level observation gauge is a transparent partition, and the overall length matches the size of the water tank.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figures 1-4 The utility model provides a technical solution: an anti-erosion device for a wind turbine concrete foundation, comprising a concrete foundation wall 1, a wall side 2, a circulation pipe 3, a mounting pipe 4, a protective component 5, a concrete layer 6, steel bars 7, a protective film 8, a fixing ring 9, a cross bar 10 and a drip groove 11. The concrete foundation wall 1 is composed of a concrete layer 6 and a protective film 8. A plurality of steel bars 7 are filled in the concrete layer 6, and the steel bars 7 extend to the left and right wall sides 2 of the concrete foundation wall 1. The protective component 5 is arranged on the circulation pipe 3, and the circulation pipe 3 is arranged on the upper surface of the concrete foundation wall 1. The circulation pipe 3 is also provided with a mounting pipe 4 at the left and right wall sides 2, and the bottom of the circulation pipe 3 is provided with a mounting pipe 4. There are multiple drip grooves 11 on the side, the fixed ring 9 is assembled in the middle part of the circulation pipe 3, and a cross bar 10 is set between the left and right fixed rings 9. The protective component 5 includes a water tank 51, a water outlet pipe 52, a hook 53, a water level observation meter 54, a slope pad 55, a timer 56 and a water pump 57. Two water pumps 57 are set inside the water tank 51, and a timer 56 is added between the two water pumps 57. The top of the water pump 57 is connected to the water outlet pipe 52, and the water outlet pipe 52 is also installed together with the circulation pipe 3. A hook 53 is also provided on the top of the water tank 51 and is connected to the cross bar 10 on the fixed ring 9. The water level observation meter 54 is evenly distributed on both sides of the surface of the water tank 51.

[0020] As the first embodiment of the present invention: the mounting pipe 4 is the port on both sides of a section of the circulation pipe 3, and matches the mounting pipe 4 on other sections of the circulation pipe 3. This design helps to connect multiple sections of the circulation pipe 3 in series, forming a complete protection for the concrete foundation of the fan. The protective film 8 is laid on the outside of the concrete foundation wall 1, and the specific material is the wall base membrane. This design helps to further enhance the alkali resistance and moisture resistance of the wall surface and improve the anti-erosion effect by adding the wall base membrane. The water level observation table 54 is a transparent partition, and the overall length matches the size of the water tank 51. The design structure is reasonable, which helps to observe the water level in the water tank 51 at any time and facilitates replenishment. Slope pads 55 inclined toward the middle are added on the left and right sides of the water tank 51. This design helps to concentrate the water in the water tank 51 near the water pump 57, thereby improving the water pumping utilization rate. The timer 56 is internally connected to the water pump 57, and the timer 56 uniformly controls the water pumps 57 on the left and right sides to work simultaneously. This design uses the timer 56 to control the operation of the water pump 57, and does not require manual operation, further reducing the pressure on the staff.

[0021] As the second embodiment of the present utility model: the surface of the wind turbine concrete foundation is provided with a wall base membrane as a protective membrane 8, which can effectively protect the concrete foundation wall 1 in a windy and sandy environment and improve its alkali resistance and moisture resistance. At the same time, the water pump 57 in the water tank 51 is controlled by the timer 56. At regular intervals, the water in the water tank 51 will be extracted through the outlet pipe 52 to flow into the circulation pipe 3. The water in the circulation pipe 3 will drip from the drip groove 11 at the bottom of the circulation pipe 3 during the process of flowing to both sides. The dripping water slowly covers the surface of the concrete foundation wall 1, moistening the protective membrane 8 on the wall, and preventing the wall from drying out due to long-term drying. There is a water level observation meter 54 on the surface of the water tank 51. The water level observation meter 54 can reflect the water storage situation in the water tank 51, which is convenient for personnel to replenish in time. The water tank 51 is hung on the cross bar 10 between the fixing rings 9 by two hooks 53, which is also convenient for disassembly.
