Description

Technical Field

[0001] This utility model relates to the field of wind power equipment technology, and in particular to a spray moisturizing device for the curing of wind turbine concrete foundations. Background Technology

[0002] Wind turbines, also known as wind power generators, are devices that convert wind energy into electrical energy. Due to their considerable weight, direct installation on the ground can easily lead to foundation settlement and instability. Therefore, concrete foundations are required when constructing wind power equipment. The concrete foundation of the wind turbine primarily serves to bear weight, isolate vibrations, and facilitate installation and adjustment. Since concrete requires curing during pouring, spraying equipment is needed to maintain the soil humidity at 60% or higher to prevent it from becoming too dry.

[0003] Currently, spray curing of concrete typically involves using a trolley carrying a water tank for mobile spraying. For example, Chinese Patent Publication No. "CN221702261 U" discloses a concrete pouring surface curing device, which includes a mobile trolley. A storage box is fixedly installed on the upper end of the mobile trolley. A water spray curing device is installed on the left side inside the storage box and extends to the bottom of the mobile trolley. A dust cleaning component is installed on the right side inside the storage box and extends to the right end of the mobile trolley.

[0004] Because the wind turbine foundation is a circular cast-in-place structure, the current spraying equipment is prone to uneven spraying when spraying the wind turbine foundation. In addition, workers need to push the trolley back and forth to spray, which is cumbersome and makes it difficult to spray the wind turbine foundation evenly. The spraying efficiency is not only low, but the workers' trampling can also affect the concrete surface. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven spraying, cumbersome and uneven spraying process, and the potential impact of workers stepping on the concrete surface. Therefore, this invention proposes a spray moisturizing device for the curing of wind turbine concrete foundations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spray moisturizing device for curing concrete foundations of wind turbines is designed, including a circular water storage tank. Support rods are hinged around the circular water storage tank through an angle limiting mechanism, and a sliding sleeve is slidably connected to the surface of the support rods through a positioning mechanism. A telescopic spray assembly is provided between the sliding sleeve and the circular water storage tank. Sliding parts are provided at the outer ends of the four support rods. A water tank is movably connected to the top of the circular water storage tank through a placement assembly.

[0008] Furthermore, the angle limiting mechanism includes several side plates fixed around the circular water tank, connecting blocks fixed at the inner ends of the four support rods, and annularly distributed through holes opened on the surface of the connecting blocks. A fixing pin is threadedly connected to the surface of one side plate, and the fixing pin engages with the through holes.

[0009] Furthermore, the positioning mechanism includes several positioning holes formed on the surface of the support rod, a U-shaped frame fixed on the surface of the sliding sleeve, an insert rod slidably connected to the top of the U-shaped frame, a fixing post fixed to the bottom of the insert rod, a spring sleeved on the surface of the insert rod, and the upper and lower sides of the spring respectively abutting against the surfaces of the U-shaped frame and the fixing post.

[0010] Furthermore, two guide strips are fixed to the inner side of the sliding sleeve, and guide grooves are provided on both sides of the support rod, with the guide strips slidably connected to the guide grooves.

[0011] Furthermore, the telescopic spray assembly includes four corrugated pipes connected to the bottom of the circular water storage tank. The surface of the corrugated pipes is provided with several equidistant fixed boxes. Atomizing nozzles are connected to the bottom of the fixed boxes. The outermost fixed box is fixed to the sliding sleeve by a connecting rod.

[0012] Furthermore, the placement assembly includes several columns fixed to the top of the circular water tank, with a placement rack having an opening at the bottom fixed to the top of each column. A gate valve is connected to the bottom of the water tank, and a threaded pipe is connected to the top of the circular water tank. The bottom of the gate valve has an internal threaded pipe for connecting with the threaded pipe, and the bottom of the gate valve is fixed to the threaded pipe.

[0013] The present invention proposes a spray moisturizing device for the curing of concrete foundations for wind turbines. The advantages are as follows: the present invention can support a circular water storage tank with four support rods, and the spraying range of the atomizing nozzles on the corrugated pipe can be adjusted by adjusting the sliding sleeves on the surface of the support rods, thereby reducing water waste. The angle of the four support rods can be adjusted by fixing pins, thereby controlling the spraying angle and adapting to different wind turbine foundations. It is not only simple in structure, but also reduces the workload of workers and improves the efficiency of maintenance. Attached Figure Description

Then connect the threaded pipe 84 to the gate valve 83. The operator places the four support rods 3 of the device on the periphery of the fan foundation. Then unscrew the fixing pin 24 and rotate the four support rods 3 to adjust the support angle. Then tighten the fixing pin 24 again. Then pull the insertion rod 43 and the fixing column 44 and squeeze the spring 45 to adjust the sliding sleeve 5. The sliding sleeve 5 can drive the bottom corrugated pipe 61 and the atomizing nozzle 63 to adjust. When maintenance is required, simply open the gate valve 83 to enter the circular water storage tank 1 and spray it out through the corrugated pipe 61 and the atomizing nozzle 63 to perform spray maintenance on the bottom circular area. The water in the water storage tank 9 generates water pressure under the action of gravity and is sprayed out through the atomizing nozzle 63.
