Description
An unmanned water-sprinkling concrete curing and cooling device Technical Field
[0001] This utility model relates to an unmanned water spraying device for concrete curing and cooling. Background Technology
[0002] Because the wind turbine tower base is located in a high-altitude mountaintop construction area with no nearby flowing water, it is not possible to directly spray water for curing after the concrete is poured. The silicate cement used in the wind turbine tower base has a large heat of hydration, and failure to spray water for cooling and curing in time may affect the performance of the concrete in various aspects and fail to meet the design requirements.
[0003] If the weather is hot and the air is dry after concrete is poured, and curing is not carried out in time, the water in the concrete will evaporate too quickly, resulting in dehydration. This will prevent the cement particles that have formed a gel from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength and thus affecting the strength of the concrete.
[0004] Cracks may form: Premature evaporation of moisture can also cause significant shrinkage and deformation, resulting in drying shrinkage cracks.
[0005] Failure to promptly water and cure large-volume concrete can lead to decreased concrete strength, surface dusting, and potentially harmful cracks. Therefore, during concrete construction, it is essential to strictly adhere to curing specifications to ensure the concrete receives adequate curing.
[0006] In existing technologies, the large wind turbine tower base is mainly cured by manual spraying after it has been cast.
[0007] Because the wind turbine tower base is large, it is difficult to maintain it evenly by hand, and the frequency of maintenance is high. It is also difficult to ensure that maintenance is timely and thorough, which can easily lead to concrete cracking due to untimely maintenance.
[0008] Based on the above problems, we designed an unmanned water spraying concrete curing and cooling device that is convenient to maintain, provides uniform curing, and avoids leaks. Summary of the Invention
[0009] The technical problem to be solved by this utility model is to provide an unmanned water spraying concrete curing and cooling device that is convenient to maintain, provides uniform curing, and avoids leaks.
[0010] To solve the above problems, the present invention adopts the following technical solution:
[0011] An unmanned concrete curing and cooling watering device includes a water level sensor, a water tank, and a controller. The controller is powered on. The water level sensor is installed inside the water tank. When the water level sensor detects that the water level in the tank is insufficient, the watering operation stops. There are two water tanks, and the water level sensor is installed in one of them. A flexible hose is detachably installed between the bottoms of the two water tanks. A support structure is installed between the two water tanks. In use, the two water tanks are located on the same diameter line of the wind turbine tower base and on the outside of the wind turbine tower base. A rotary spray device is installed through the support structure. The controller is connected to and controls the rotary spray device, which draws water from the two water tanks.
[0012] Preferably, the support structure includes a metal support body with ring-shaped bodies machined at both ends. The upper end of the water tank is provided with a pipe opening, and the ring-shaped bodies are fitted onto the pipe opening. The lower part of the pipe opening is a conical surface, and the ring-shaped bodies are positioned by the conical surface. A shaft tube is provided in the middle of the support body, and the rotary spray device rotates along the shaft tube.
[0013] Preferably, a rubber gasket is fitted onto the inner wall of the annular body, and the rubber gasket contacts the pipe opening.

[0015] Preferably, the rotary spray device includes a hollow shaft, a spray pipe, a nozzle, a drive motor, and a water pump. The hollow shaft passes through the shaft tube, with its lower end closed and a water inlet cap installed at its upper end. A bearing is fitted between the hollow shaft and the shaft tube. Two or more connecting pipes are arranged in a ring near the lower end of the outer wall of the hollow shaft. One end of the spray pipe is closed, and the other end is fixedly installed to the connecting pipe. The nozzle is installed on the wall of the spray pipe and sprays vertically downwards or at an angle downwards. A side bracket is welded between the water inlet cap and the support body. A first bearing and a shaft seal are fitted between the hollow shaft and the water inlet cap, with the shaft seal sealing the upper part of the first bearing. A transmission mechanism is fitted between the drive motor and the hollow shaft.

A T-pipe is installed at the water inlet end of the water pump, and extension pipes are installed through both ends of the T-pipe. A first flexible hose is fixed to the end of the extension pipe by a clamp. The first flexible hose is inserted into the water tank. A pump water pipe connects the water pump and the water inlet cap.
[0016] Preferably, the transmission mechanism is a belt drive mechanism or a chain drive mechanism.
[0017] Preferably, the rotation radius of the spray pipe is greater than the radius of the wind turbine tower base.
[0018] Preferably, the nozzle is at an angle of -30° to -90° relative to the horizontal plane.
[0019] The beneficial effects of this utility model are:
[0020] This equipment is equipped with a water delivery truck, which transports water from a distance to the equipment to fill both water tanks (the water capacity of both tanks must be sufficient to maintain the foundation of one wind turbine tower). The water stored in the tanks meets the needs of spray curing, eliminating the need for other external water sources. The water delivery truck can leave directly after filling the tanks, without the need for on-site water supply. The device is flexible in assembly, simple in application, easy to operate, and highly practical. Furthermore, the rotary spray curing method avoids leaks and ensures more uniform curing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] Referring to Figure 1, an unmanned concrete curing and cooling watering device includes a water level sensor, a water tank 1, and a controller. The controller is connected to electricity. The water level sensor is installed inside the water tank 1. When the water level sensor detects that the water level in the water tank 1 is insufficient, the watering operation stops. There are two water tanks 1, and the water level sensor is installed in one of the water tanks 1. A flexible hose 11 is detachably installed between the bottoms of the two water tanks 1. A support structure 2 is installed between the two water tanks 1. In use, the two water tanks 1 are located on the same diameter line of the wind turbine tower base and are located outside the wind turbine tower base. A rotary spray device 3 is installed through the support structure 2. The controller is connected to and controls the rotary spray device 3. The rotary spray device 3 draws water from the water tanks 1 at both ends.
[0033] In the above technical solution, two water tanks 1 are hoisted to both sides of the wind turbine tower base by hoisting, and then the support structure 2 is hoisted. The start and stop times of the spraying are set by the controller, as well as the rotation speed of the rotary spraying device 3, so as to realize the automatic maintenance of the wind turbine tower base.
[0034] The slow rotation of the rotary spray device 3 (5~10 revolutions / minute) evenly sprays water downwards onto the surface of the wind turbine tower base, making the spraying curing more uniform and providing complete coverage without any dead corners.
[0035] Referring to Figures 2 and 3, the support structure 2 includes a metal support body 21, with annular bodies 22 formed at both ends of the support body 21. The upper end of the water tank 1 is provided with a pipe opening 12, and the annular body 22 is fitted onto the pipe opening 12. The lower part of the pipe opening 12 is a conical surface 13, and the annular body 22 is positioned by the conical surface 13. A shaft tube 24 is provided in the middle of the support body 21, and the rotary spray device 3 rotates along the shaft tube 24.
[0036] In the above technical solution, the use of the conical surface 13 and the annular body 22 to achieve the positioning and installation of the bracket body 21 makes the installation of the bracket body 21 more stable.
[0037] Referring to Figures 1 and 3, a rubber gasket 23 is fitted into the inner wall of the annular body 22, and the rubber gasket 23 contacts the opening 12.
[0038] The rubber gasket 23 allows for a tighter fit between the annular body 22 and the nozzle 12, reducing assembly gaps and making the support body 21 more stable.
[0039] Referring to Figure 3, lifting rings 4 are welded to the top of both the water tank 1 and the support body 21.
[0040] The lifting ring 4 facilitates the hoisting of the water tank 1 and the support body 21, and makes the installation and dismantling of this equipment convenient.
[0041] Referring to Figures 2, 3, and 4, the rotary spray device 3 includes a hollow shaft 31, a spray pipe 32, a nozzle 33, a drive motor 34, and a water pump 35. The hollow shaft 31 passes through the shaft tube 24, with its lower end closed and a water inlet cap 310 installed at its upper end. A bearing 311 is fitted between the hollow shaft 31 and the shaft tube 24. Two or more connecting pipes 312 are arranged in a ring near the lower end of the outer wall of the hollow shaft 31. One end of the spray pipe 32 is closed, and the other end is fixedly installed to the connecting pipe 312. The nozzle 33 is installed on the pipe wall of the spray pipe 32 and sprays vertically downwards or at an angle downwards. A side bracket 313 is welded between the water inlet cap 310 and the support body 21. A first bearing 314 and a shaft seal 315 are fitted between the hollow shaft 31 and the water inlet cap 310. The shaft seal 315 seals the upper part of the first bearing 314. A transmission mechanism 341 is fitted between the drive motor 34 and the hollow shaft 31. The drive motor 34 and the water pump 35 are both installed on the top of the bracket body 21 and are respectively located on the left and right sides of the hollow shaft 31. A three-way pipe 351 is installed at the water inlet end of the water pump 35. Extension pipes 352 are installed through both ends of the three-way pipe 351. A first flexible hose 353 is fixed at the end of the extension pipe 352 by a clamp. The first flexible hose 353 is inserted into the water tank 1. A pump pipe 354 connects the water pump 35 and the water inlet cap 310.
[0042] In the above technical solution, both the water pump and the drive motor are controlled by a controller. The controller controls the water pump and the drive motor to run synchronously. When the water level sensor detects that the water level is insufficient, the water pump and the drive motor are stopped simultaneously.
[0043] The hollow shaft is driven to rotate by a drive motor. Water is drawn from the water tanks 1 on both sides by a water pump and then fed into the hollow shaft 31 through the water inlet cap 310. The water is then sprayed by multiple ring-shaped spray pipes 32 with nozzles 33, achieving rotary curing and ensuring that the concrete curing is thorough.
[0044] After the set maintenance time is reached, the water pump and drive motor will stop.
[0045] Referring to Figure 2, the transmission mechanism 341 is a belt drive mechanism or a chain drive mechanism.
[0046] In this embodiment, a belt drive mechanism is used.
[0047] The rotation radius of the spray pipe 32 is greater than the radius of the wind turbine tower base.
[0048] The diameter of the wind turbine tower base is usually 15 to 20 meters, and the length of a single spray pipe is greater than the radius of the wind turbine tower base being maintained.
[0049] Referring to Figure 5, the nozzle 33 has an angle of -30° to -90° relative to the horizontal plane.
[0050] This technical solution ensures that the nozzle 33 can only spray vertically downwards or tilt downwards, avoiding excessively high spray angles.
[0051] In this embodiment, the nozzle 33 has an angle of -90°, meaning the nozzle 33 is pointing vertically downwards.
