Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, specifically to a concrete curing spray device. Background Technology

[0002] When concrete is poured in hot and dry weather, if water is not sprayed to cool and cure it in time, the water in the concrete will evaporate too quickly, resulting in insufficient hydration of the cement particles that have formed a gel, unstable crystallization, and lack of bonding strength. This can lead to flaking or powdering on the concrete surface, or even cracks. Therefore, curing in the initial stage after concrete pouring is very important.

[0003] Current maintenance methods mostly involve manual spraying with water hoses. On the one hand, workers need to hold the nozzles and pull the hoses constantly, which is physically demanding and inefficient. This is especially true for large-scale projects, where it can significantly impact construction progress, increase costs, and cause high wear and tear on the hoses. On the other hand, manual operation makes it difficult to accurately control the amount of water used for spraying, especially in extreme weather conditions. Manual maintenance may fail to meet the precise requirements for concrete curing, resulting in localized over- or under-spraying of water on the concrete surface, which can negatively impact the concrete's performance and durability. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-4 As shown, it includes a main body 1, with several casters 2 at the bottom of the main body 1, a water storage chamber 4 inside the main body 1, a component cavity 11 and a battery compartment 6 above the water storage chamber 4, and a water spray port 10 on the front side of the component cavity 11; the component cavity 11 is equipped with a multi-head spray assembly and a uniform adjustment structure that cooperates with the multi-head spray assembly.

[0026] See Figures 1-6As shown, the multi-head spray assembly includes several spray pipes 18 disposed in the component cavity 11. The spray pipes 18 are arranged in a fan shape, and each spray pipe 18 passes through the water spray port 10. One end of each spray pipe 18 located in the component cavity 11 is rotatably installed in the component cavity 11 via the main rotating shaft 17. A water pump 12 is provided in the component cavity 11. The water pump 12's pumping end is connected to the bottom of the water storage chamber 4 via a pumping pipe 13. The water pump 12's outlet end is connected to a water distributor 15 via an outlet pipe 14. The outlet end of the water distributor 15 is connected to the spray pipes 18 via connecting pipes 16. The area between the spray pipe 18 and the two connection points of the main rotating shaft 17 and the connecting pipe 16 is in a closed state. The front end of the spray pipe 18 is connected to a spray head 19. A water supply pipe 5 is provided on the side of the device body 1. One end of the water supply pipe 5 passes through the device body 1 and is located in the water storage chamber 4.

[0027] As an optimized solution of this utility model, water can be drawn from the water storage chamber 4 by the water pump 12, and the water is divided into multiple spray pipes 18 by the water distributor 15, and then sprayed out from the spray head 19. The water distributor 15 can ensure the water pressure balance in the multiple spray pipes 18, ensuring uniform spraying, and the tail end of the spray pipe 18 is sealed to prevent water leakage; the water filling pipe 5 can facilitate the user to add water to the water storage chamber 4.

[0028] See Figures 1-6 As shown, the uniform adjustment structure includes several drive slide rails 20 corresponding to each spray pipe 18 below it, and each drive slide rail 20 is located at one end of the spray pipe 18 near the main rotating shaft 17. Each drive slide rail 20 is slidably mounted with a drive slider 21, and a drive rotating shaft 22 is rotatably connected to the drive slider 21. A drive rod 23 is provided horizontally below the drive slide rail 20. The lower ends of several drive rotating shafts 22 are all connected to the drive rod 23. Two drive motors 24 are provided at the bottom of the component cavity 11. A drive screw 25 is connected to the drive shaft of each drive motor 24. The front end of the drive screw 25 is installed in the component cavity 11 through a bearing seat. The two ends of the drive rod 23 are respectively threaded onto the two drive screws 25.

[0029] As an optimized solution of this utility model, two drive motors 24 are used as drive sources, and drive rods 23 are moved by drive screws 25 respectively. In turn, drive sliders 21 are moved along drive rails 20 by drive shafts 22. Since several drive shafts 22 are set on drive rods 23 and the distance between adjacent drive shafts 22 is fixed, several spray pipes 18 can be driven to rotate synchronously along their respective main shafts 17 at the same time, thereby synchronously adjusting the angle of multiple spray pipes 18.

[0030] See Figures 1-4As shown, a lithium battery pack 7 is installed in the battery compartment 6, and the lithium battery pack 7 is electrically connected to the water pump 12; a charging port 8 and a control switch 9 are provided on one side of the lithium battery pack 7, the charging port 8 is electrically connected to the lithium battery pack 7, and the control switch 9 is electrically connected to the water pump 12.

[0031] As an optimized solution of this utility model, the lithium battery pack 7 can provide power to the device and maintain a long battery life, the charging port 8 facilitates charging of the lithium battery pack 7, and the control switch 9 facilitates the operator to start and stop the device.

[0032] See Figures 1-2 As shown, the device body 1 has a push handle 3 on the rear side and the moving wheel 2 is a universal wheel with a locking structure.

[0033] As an optimized solution of this utility model, the push handle 3 facilitates workers to push the device for spraying operations, while the casters ensure the mobility of the device and allow for quick directional adjustments.

[0034] The usage process of this utility model:

[0035] First, the user fully charges the lithium battery pack 7 through the charging port 8, and then fills the water storage chamber 4 with water through the water filling pipe 5. The device can then be pushed to the designated location by pushing the handle 3. Next, the water pump 12 is started by controlling the switch 9. The water pump 12 draws water and sprays it from the spray head 19. The user can adjust the spraying range according to the required width of the concrete to be sprayed: Starting the drive motor 24 causes the drive rod 23 to move forward via the drive screw 25, which in turn rotates the spray pipe 18 inward synchronously through several drive rails 20 and drive sliders 21. Simultaneously, the drive shaft 22 rotates adaptively, reducing the spraying range and increasing the spraying density within the area. Reversing the drive motor 24 causes the drive rod 23 to move backward, thereby increasing the spraying range and decreasing the spraying density within the area.

[0036] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
