Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a curing spraying mechanism for wind power generation concrete towers. Background Technology

[0002] The concrete tower of a wind turbine is the supporting structure of the wind turbine generator, generally made of reinforced concrete. Its height allows the wind turbine to be raised to a suitable height to capture more stable wind energy. Wind turbine concrete towers typically require spray curing. Spray curing keeps the concrete surface moist, preventing quality problems such as cracking caused by excessive moisture evaporation, and is beneficial for the strength development and performance stability of the concrete. Spray curing is especially important in dry, high-temperature environments.

[0003] Currently, most spray curing mechanisms for concrete wind turbine towers are fixed. These devices rely on pre-installed spray pipes for curing operations, which has significant limitations: the fixed location of the spray pipes restricts the curing area that can be covered, making it difficult to meet the curing needs of different parts of the tower. The actual application effect is unsatisfactory and requires improvement and optimization. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a curing spraying mechanism for wind power generation concrete towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A curing spraying mechanism for a wind power generation concrete tower includes a vertically arranged tower body. A horizontally arranged mounting ring and a support ring are fixedly sleeved at the upper and lower ends of the tower body, respectively. A lifting ring is slidably sleeved on the outer wall of the tower body. Multiple counterweights are fixedly connected to the lower end of the lifting ring. Multiple guide rods arranged in a ring are slidably inserted inside the lifting ring. The guide rods are vertically arranged, with both ends passing through the lifting ring and fixedly connected to the mounting ring and the support ring, respectively. A ring-shaped water tank is provided inside the lifting ring. Multiple spray heads communicating with the water tank are fixedly inserted into the inner wall of the lifting ring.

A winding reel is fixedly sleeved on the output shaft of the servo motor. A connecting rope is fixedly connected to the winding reel. An opening is provided at the bottom of the storage slot. The lower end of the connecting rope slides through the opening and is fixedly connected to the upper end of the lifting ring.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A curing spraying mechanism for a wind power concrete tower includes a vertically arranged tower body 1. A horizontally arranged mounting ring 2 and a support ring 3 are fixedly sleeved at the upper and lower ends of the tower body 1, respectively. The mounting ring 2 supports a servo motor 10, and the support ring 3 supports a guide rod 5. A lifting ring 4 is slidably sleeved on the outer wall of the tower body 1 to drive the spray head 11 to rise and fall. Multiple counterweights 6 are fixedly connected to the lower end of the lifting ring 4 to increase its weight. Multiple guide rods 5 arranged in a ring are slidably inserted inside the lifting ring 4 to guide its rise and fall. The guide rods 5 are vertically arranged, with both ends of the guide rod 5 passing through the lifting ring 4 and fixedly connected to the mounting ring 2 and the support ring 3, respectively. Fixed rings 13 are fixedly sleeved at both ends of the guide rod 5 to support it. The opposite sides of the two fixed rings 13 are fixedly connected to the lower end of the mounting ring 2 and the upper end of the support ring 3, respectively. In this embodiment, the lifting ring 4 is provided with a ring-shaped water tank for water circulation. Multiple spray heads 11 communicating with the water tank are fixedly inserted on the inner side wall of the lifting ring 4 for spraying water. Two first sealing rings are fixedly sleeved on the spray heads 11 to improve the sealing performance. The two first sealing rings are fixed on the inner and outer sides of the lifting ring 4 respectively. A water supply pipe 7 communicating with the water tank is fixedly connected to the lower end of the lifting ring 4 for transporting water. The water supply pipe 7 is a telescopic flexible hose to allow the water supply pipe 7 to rise and fall with the lifting ring 4. Two second sealing rings are fixedly sleeved on the water supply pipe 7 to improve the sealing performance. The two second sealing rings are fixed on the inner and outer sides of the lifting ring 4 respectively. In this embodiment, the mounting ring 2 is provided with a storage groove. A servo motor 10 is fixedly connected to the inner wall of the storage groove to drive the winding wheel 9 to rotate. The output shaft end of the servo motor 10 is rotatably connected to the inner wall of the storage groove. The winding wheel 9 is fixedly sleeved on the output shaft of the servo motor 10 to wind or unwind the connecting rope 8. The connecting rope 8 is fixedly connected to the winding wheel 9 to pull the lifting ring 4 upward. The connecting rope 8 is made of steel wire to improve strength and reliability. The bottom of the storage groove is provided with an opening. The lower end of the connecting rope 8 slides through the opening and is fixedly connected to the upper end of the lifting ring 4. A fixing cylinder 12 is fixedly sleeved on the lower end of the connecting rope 8 to improve the firmness of the lower end of the connecting rope 8. The lower end of the fixing cylinder 12 is fixedly connected to the upper end of the lifting ring 4.

[0017] In this embodiment, firstly, the water supply pipe 7 is connected to an external high-pressure water source or water pump, allowing the high-pressure water to flow into the water tank through the water supply pipe 7. Then, the water in the water tank is sprayed onto the surface of the tower 1 through multiple ring-shaped spray nozzles 11. This ring-shaped arrangement of multiple spray nozzles can fully cover the surface of the tower 1, effectively expanding the spraying range and reducing blind spots. After completing the spraying preparation, the servo motor 10 is started to drive the winding reel 9 to reverse, causing the winding reel 9 to unwind the connecting rope 8. At this time, the tower, which has lost the support of the connecting rope 8, is lifted... The lowering ring 4 descends steadily and slowly under the gravity of the counterweight 6. When it is necessary to raise the lifting ring 4, simply start the servo motor 10 to drive the winding wheel 9 to rotate forward. The winding wheel 9 will then wind up the connecting rope 8, which will drive the lifting ring 4 to rise. Through the above operation, the lifting ring 4 can be raised. Since the spray head 11 is installed on the lifting ring 4, the raising and lowering of the lifting ring 4 can drive the spray head 11 to spray different height positions of the tower body 1, ensuring that all parts of the tower body 1 can be sprayed.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
