Description

Technical Field

[0001] This utility model relates to the field of wind turbine foundation maintenance technology, specifically a wind turbine foundation maintenance device. Background Technology

[0002] After the concrete foundation for the wind turbine is poured, it typically requires 2-3 days to reach initial setting, followed by 7-14 days of static curing. During this period, the transport or operation of large machinery near the foundation is strictly prohibited. Controlling the ambient humidity is crucial during the curing process. Humidity control can be achieved through methods such as spraying, covering with damp cloths, or covering with a moisture-retaining film.

[0003] In existing technologies, moisturizing by directly covering with a damp cloth can easily lead to a decrease in moisturizing effect after evaporation. When moisturizing by spraying, the sprayed water is directly sprayed onto the surface of the wind turbine foundation, and the water slides directly down the surface of the wind turbine foundation, resulting in water waste. Therefore, a wind turbine foundation maintenance device is proposed to optimize the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine foundation maintenance device to solve the problem mentioned in the background art that the moisturizing effect is easily reduced after evaporation when the wet cloth is directly covered for moisturizing. When moisturizing by spraying, the spray water is directly sprayed onto the surface of the wind turbine foundation and the water directly slides down the surface of the wind turbine foundation, resulting in water waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind turbine foundation maintenance device includes a moisture-retaining cloth layer covering the surface of the wind turbine foundation. A sponge water-retaining layer is fixedly connected to the outer surface of the moisture-retaining cloth layer. A spray pipe adapted to the wind turbine foundation is provided on the outer side of the wind turbine foundation. Spray nozzles corresponding to the wind turbine foundation are evenly distributed on the spray pipe. The top end of the spray pipe is connected to a water inlet pipe. The bottom end of the water inlet pipe is provided with a fixing mechanism for fixed installation with the wind turbine foundation. A rotating assembly is rotatably installed on the outer side of the water inlet pipe. The top end of the spray pipe is fixedly connected to the rotating assembly and is interconnected with it. A connecting hole is opened on the water inlet pipe corresponding to the rotating assembly. The water inlet pipe is connected to an external water supply pipe.

The external water supply pipe is a pressurized water supply, so that spraying can be performed through the spray nozzles 5.

[0024] A moisturizing cloth layer 2 is installed on the surface of the wind turbine foundation for moisturizing. At the same time, the sponge water storage layer 3 can store a large amount of water to keep the moisturizing cloth layer 2 always moist. Even in the case of rapid evaporation, water can be sprayed through the spray pipe 4 and the nozzle 5 to maintain the moisture. When the nozzle 5 sprays water, the water is sprayed onto the sponge water storage layer 3 and absorbed, preventing the water from flowing directly downwards, thus effectively maintaining a continuous moist state.

[0025] A fixing plate 17 is fixedly connected to the top side of the water inlet pipe 6. The fixing plate 17 is an L-shaped plate. A drive motor 9 is fixedly installed on the fixing plate 17. The drive motor 9 is connected to a power supply and a switch. The drive motor 9 is a geared motor. A drive gear 10 is fixedly connected to the output end of the drive motor 9. A driven gear 11 that meshes with the drive gear 10 is provided on the outside of the drive gear 10. The driven gear 11 is fixedly connected to the rotating assembly 7 and is concentrically arranged with the rotating assembly 7.

[0026] A roller 12 is rotatably mounted at the bottom end of the spray pipe 4.

[0027] The bottom end of the spray pipe 4 can move via the roller 12, and the top end of the spray pipe 4 is rotatably connected to the water inlet pipe 6 via the rotating assembly 7. Driven by the drive motor 9, the rotating assembly 7 is rotated by the drive gear 10 and the driven gear 11, so that the spray pipe 4 can rotate, thereby spraying and replenishing the sponge water storage layer 3.

[0028] The fixing mechanism includes a cross-shaped fixing bracket 13, and the water inlet pipe 6 is fixedly connected to the top surface of the cross-shaped fixing bracket 13.

[0029] The four ends of the cross-shaped fixing bracket 13 are threaded with rotating threaded handles 14. The four ends of the cross-shaped fixing bracket 13 are provided with folded edges, and threaded holes for threaded connection of rotating threaded handles 14 are opened on the folded edges. The ends of rotating threaded handles 14 are rotatably connected with extrusion plates 15. The extrusion plates 15 slide in contact with the cross-shaped fixing bracket 13. The extrusion plates 15 correspond to the top of the fan base 1 and can be extruded onto the moisturizing cloth layer 2 or the sponge water storage layer 3.

[0030] The cross-shaped fixing bracket 13 rests on the top of the fan base 1. By rotating the threaded handle 14, the extrusion plate 15 is driven to move, thereby achieving clamping and fixing with the top of the fan base 1, so that the water inlet pipe 6 is fixedly connected to the fan base 1, thus fixing the device.

[0031] The moisturizing fabric layer 2 is composed of multiple fan-shaped fabric pieces, which are connected by zippers 16. The sponge water-retaining layer 3 is designed in the same fan shape as the moisturizing fabric layer 2, thereby fixing each fan-shaped fabric piece.

[0032] The moisture-retaining fabric layer 2 is made of multiple fan-shaped fabric pieces connected by zippers 16 to form a modular assembly, which can be easily wrapped and connected to the outside of the fan foundation 1.

[0033] The working principle of this utility model is as follows:

[0034] In use, first, the moisturizing cloth layer 2 is laid on the outside of the fan base 1, and the sponge water storage layer 3 is laid simultaneously. Then, the fan-shaped pieces of adjacent moisturizing cloth layers 2 are connected into a whole using the zipper 16. Next, the cross-shaped fixing bracket 13 is placed on top of the fan base 1. Then, the rotating threaded handle 14 is rotated, driving the extrusion plate 15 to move, thereby clamping and fixing it to the top of the fan base 1, so that the water inlet pipe 6 is fixedly connected to the fan base 1. Furthermore, a water inlet pipe is connected to the external water inlet pipe 6, allowing water to be supplied. The liquid enters the rotating assembly 7 through the connecting hole 8, then enters the spray pipe 4, and finally is sprayed onto the sponge water storage layer 3 through the nozzle 5. The sponge water storage layer 3 absorbs the liquid, and at the same time, the moisturizing cloth layer 2 is soaked with the liquid, thus moisturizing and covering the fan base 1 through the moisturizing cloth layer 2. At the same time, the drive motor 9 can drive the drive gear 10 to rotate, the drive gear 10 drives the driven gear 11, the driven gear 11 drives the rotating assembly 7 to rotate, which in turn causes the spray pipe 4 to rotate and move, so that the spray pipe 4 can spray the sponge water storage layer 3 comprehensively through the nozzle 5.
