[0038] As Figures 1 to 6 shown: A concrete curing device includes a spraying assembly 1 and a support assembly 2 arranged up and down;

[0039] The spraying assembly 1 includes a base 11, a main rod 12, and a spraying rod 13. The base 11 is fixedly connected to the top of the support assembly 2. A water pipe interface 111 is provided on the base 11 for pumping external water source into the spraying assembly 1;

[0040] The main rod 12 is arranged on the base 11. One end of at least two spraying rods 13 is arranged on the main rod 12, and the spraying rods 13 are centrosymmetric along the axis of the main rod 12. A rotating sleeve 121 is provided on the main rod 12. A plurality of nozzles 131 are provided on the spraying rods 13, and the nozzles 131 on each spraying rod 13 are inclined towards one radial side of the spraying rod 13;

[0041] Among them, the water flow passes through the water pipe interface 111, the main rod 12, the spraying rod 13, and the nozzles 131 in sequence, and sprays towards the same side along the inclined nozzles 131. The flowing of the sprayed water flow drives the spraying rod 13 to rotate along the axis of the rotating sleeve 121;

[0042] The bottom of the support assembly 2 is provided with rollers 21 with a self-locking function for moving the support assembly 2, so as to facilitate moving to other concrete areas that need to be sprayed with water.

[0043] The flow of water drives the spraying rod 13 to rotate along the axis of the rotating sleeve 121, enabling the spraying rod 13 to automatically rotate and spray evenly. Compared with the traditional manual spraying method, it can ensure that the water evenly covers the concrete surface, avoid the difference in curing quality caused by uneven spraying, and thus effectively improve the hardening effect and strength uniformity of the concrete.

[0044] The flow of water is used to drive the rotation of the spraying rod 13, eliminating the need for an additional power system, thereby reducing energy consumption and the use of complex mechanical structures, and lowering the manufacturing and maintenance costs of the device.

[0045] The bottom of the bracket assembly 2 is equipped with rollers 21 with a self-locking function, making it more convenient for the device to move between different areas. At the same time, the self-locking function can ensure the stability of the device at the selected position. The curing device can be freely adjusted according to different construction requirements, improving the adaptability and convenience of the equipment and reducing the manual operation burden.

[0046] In this embodiment, as Figure 1 、 2 shown, the number of spraying rods 13 is three, symmetrically arranged along the axis center of the main rod 12. The number of spraying rods 13 can also be two, four, etc., all within the protection scope of this application.

[0047] As a preference of the above embodiment, as Figure 3 shown, the nozzles 131 are inclined in the direction away from the main rod 12. On the one hand, it enables the water flow to spray to a farther area, thereby expanding the spraying coverage range, and can ensure that the concrete curing area is more comprehensively covered by water. Especially in the case of a large curing area, it effectively reduces the area where the hardening of the concrete is affected due to insufficient water. On the other hand, the design of the nozzles 131 being inclined away from the main rod 12 makes the sprayed water flow more easily evenly distributed throughout the curing area. Compared with the nozzles 131 spraying vertically, the inclined spraying can reduce the situation where water droplets concentrate at the same position, thereby reducing the risk of local water accumulation and improving the overall uniformity of curing.

[0048] In this embodiment, referring to Figure 4, the top of each nozzle 131 is a hemispherical structure 131a, and a number of spray holes 131b are provided on the hemispherical structure 131a. On the one hand, the multiple spray holes 131b on the hemispherical structure 131a enable the water flow to be ejected from multiple angles, thereby achieving a multi-angle spraying effect. The multi-directional water flow distribution enables the maintenance device to cover a wider range. Especially in large-area concrete structures that require comprehensive spraying maintenance, the efficiency of maintenance and the uniformity of coverage are effectively improved. On the other hand, the hemispherical structure 131a disperses the pressure when the water flow passes through the spray holes 131b, forming a relatively gentle spraying effect, thereby reducing the direct impact of the water flow on the surface of the newly poured concrete. The spraying method with a lower impact force can effectively avoid the damage caused by the water flow to the surface of the concrete that has not been fully hardened, ensuring the surface quality of the concrete.

[0049] Among them, continue to refer to Figure 4 , the spray hole 131b is a tapered hole that gradually expands from the inner wall to the outer wall. Specifically, the tapered hole gradually expands the outlet area when the water flow passes through the spray hole 131b, generating an effect similar to the Venturi effect, thereby enhancing the atomization degree of the water flow. The optimized water flow path can make the sprayed water flow more delicate, further achieving a uniform and gentle spraying effect, and improving the wetting quality of the concrete surface. The gradually expanding structure of the tapered hole can stabilize the water flow passing through the nozzle 131, reducing the formation of turbulence and disorderly flow, thereby ensuring that the sprayed water flow is more stable and uniform, contributing to maintaining a consistent humidity coverage during the concrete maintenance process and ensuring that the entire surface is evenly wetted.

[0050] For a flat road surface, the fixed support assembly 2 can meet the requirements. However, in the actual construction process, there may be some high-rise buildings, such as flower beds of a certain height. The height of the fixed support assembly 2 may not be able to cover the height of the flower bed, so that the support assembly 2 needs to be raised to a certain height to spray the corresponding area. Therefore, it is required that the height of the support assembly 2 is adjustable to increase the adaptability of the device. Therefore, the following improvements are made to the support assembly 2:

[0051] As a preference of the above embodiment, the support assembly 2 further includes a base 22, a support 23, and an adjustment device between the base 22 and the support 23;

[0052] The base 22 is detachably connected to the base 11;

[0053] The adjusting device includes a sleeve 24, an adjusting nut 25 and a lead screw 26; the adjusting nut 25 is arranged at one end of the sleeve 24, and the lead screw 26 is at least partially arranged inside the sleeve 24. Rotating the adjusting nut 25 is used to adjust the distance that the lead screw 26 inserts into the sleeve 24, so as to adjust the height between the bracket 23 and the base 22. Specifically, through the cooperation of the adjusting nut 25 and the lead screw 26, the height adjustment can be achieved only by rotating the adjusting nut 25. The operation is simple and fast. Construction workers can easily complete the height adjustment of the bracket 23 without complex tools or a large amount of physical strength, thereby improving work efficiency and reducing the difficulty of on-site operation.

[0054] Among them, at least two handles 251 are radially arranged on the adjusting nut 25. Specifically, the addition of the handles 251 facilitates the construction workers to manually adjust the nut 25, and the height adjustment can be completed without additional tools. The adjusting nut 25 can be easily rotated through the handles 251, making the height adjustment more rapid and convenient, especially suitable for the situation of frequently adjusting the height of the bracket 23 on site.

[0055] As a preference of the above embodiment, as Figure 5 shown, the bracket 23 includes a cross bar 231, an inclined bar 232 and a second connecting member 233;

[0056] The second connecting member 233 is arranged on the sleeve 24;

[0057] The cross bar 231 is horizontally arranged, and one end is fixedly connected to the sleeve 24;

[0058] The top of the inclined bar 232 is connected to the second connecting member 233, and the bottom is connected to the end of the cross bar 231, so that a stable triangular structure is formed between each group of the cross bar 231, the inclined bar 232 and the sleeve 24, thereby greatly improving the stability of the bracket 23. The triangular structure has excellent anti-deformation performance in mechanics and can effectively disperse external forces from all directions, preventing the bracket 23 from tilting or shaking and ensuring the stability of the device in different construction environments.

[0059] In this embodiment, referring to Figure 1 、 Figure 6, a first connecting member 112 is provided at the bottom of the base 11. Corresponding hanging ears 221 are provided on both the first connecting member 112 and the base 22. A groove 222 is provided inside the hanging ear 221, and a screw rod 223 is provided inside the groove 222. A rotating shaft 224 is provided between one end of the screw rod 223 and the hanging ear 221 on one side. The screw rod 223 rotates along the rotating shaft 224, and a wing nut 225 is provided on the screw rod 223 for locking the two hanging ears 221. On the one hand, by providing the screw rod 223 and the wing nut 225 between the two hanging ears 221, in the locked state, the wing nut 225 presses the two hanging ears 221 tightly, thereby ensuring the tight connection between the base 11 and the bracket assembly 2. This design can effectively improve the stability of the connection, avoid loosening or falling off of the device during use, and ensure the stability of the entire device.

[0060] Among them, blind holes 226 are provided on the surfaces where the first connecting member 112 is in contact with the base 22. Positioning pins 27 are provided inside the blind holes 226 for the quick alignment between the first connecting member 112 and the base 22. Specifically, in this embodiment, the positioning pin 27 can be rectangular, or other shapes, such as pentagonal, hexagonal, etc., which are all within the protection scope of this application, making the installation faster and more accurate, and improving the construction efficiency; the rectangular positioning pin 27 forms a stable positioning structure between the first connecting member 112 and the base 22, avoiding misalignment or displacement of the connecting member due to vibration or external force after assembly. This structure can improve the stability of the device, ensure that the connecting member always remains aligned during use, and enhance the overall stability of the device.

[0061] For the above solution, after spraying one area each time, it is necessary to manually move the concrete curing device to the corresponding area, which is rather troublesome during use. Therefore, the following improvements are made:

[0062] As a preference of the above embodiment, a control component is further provided on the bracket assembly 2. The control component is connected to the operation end and is used to control the movement of the rollers 21. Specifically, the control component can flexibly control the movement of the rollers 21 through the operation end, enabling the curing device to quickly move and position at the construction site without manual pushing, greatly improving the movement efficiency of the device. Especially in the construction environment of large areas or complex terrains, remotely controlling the movement of the device significantly reduces the manpower requirement; through the control component, the operation of the device is more intelligent, and it can move and position accurately according to the curing requirements. The connection between the control component and the operation end enables the operator to remotely control the equipment and achieve automatic control, which helps to improve the construction efficiency and accuracy.
