Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a movable, foldable environmental protection dust suppression device for construction engineering. Background Technology

[0002] Dust control during construction is a key aspect of green construction, and spray dust suppression technology is widely used due to its high efficiency and economy. This technology uses a high-pressure system to atomize water into micron-sized fine mist, which is then sprayed into the dusty area. The water mist particles quickly adsorb airborne dust particles, causing them to become heavier and settle, effectively inhibiting dust diffusion at its source.

[0003] To expand their effective range, existing spray dust suppression devices typically increase the power of water pumps or raise water pressure to increase spray distance and coverage area. However, this approach leads to a significant increase in energy consumption and operating costs, and may exacerbate nozzle wear and water mist evaporation. Alternatively, the effective area can be expanded by raising the installation height of the nozzles, but this results in a bulky overall structure that occupies a lot of space, making it extremely inconvenient to move and store, thus limiting its application flexibility in space-constrained or frequently relocated work scenarios. Utility Model Content

[0004] The present invention aims to provide a movable, foldable, environmentally friendly dust suppression device for construction engineering, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A movable, foldable, environmentally friendly dust suppression device for construction engineering includes a base plate, a water tank and a water pump connected to the base plate, a rotatable base connected to the base plate, a mounting frame connected to the base, a drive structure connected to the mounting frame, a first rotating arm rotatably connected to the inner wall of the mounting frame, a connecting plate connected to the first rotating arm, a second rotating arm rotatably connected to the inner wall of the connecting plate, a dust suppression nozzle connected to the second rotating arm, and a water pump connected to the dust suppression nozzle and the water tank via connecting pipes. The first and second rotating arms are jointly connected to an unfolding structure.

[0007] The unfolding structure includes a cylinder, the first rotating arm has a second storage slot, the second rotating arm has a first storage slot, the inner walls of the first and second storage slots are rotatably connected to a connecting ring, the cylinder is rotatably connected to the inner wall of the second storage slot, the output end of the cylinder is connected to a push plate, and the push plate is rotatably connected to the connecting ring.

[0008] Preferably, the drive structure includes a motor connected to a mounting bracket, a worm gear connected to the output end of the motor, the other end of the worm gear being rotatably connected to the base, and a worm wheel connected to the first rotating arm, the worm wheel meshing with the worm gear.

[0009] Preferably, the first rotating arm and the second rotating arm are respectively provided with rotating grooves.

[0010] Preferably, the base plate is connected to a plurality of self-locking casters.

[0011] Preferably, the base plate is connected to a push handle.

[0012] Preferably, the base plate is connected to sleepers.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] (1) This utility model features an unfolding structure consisting of a cylinder, a connecting ring, and a push plate. The cylinder is hinged to the second storage slot of the first rotating arm, and the connecting ring is hinged to both the first and second storage slots. This design allows the cylinder to drive the connecting ring via the push plate during extension and retraction, thereby synchronously controlling the first and second rotating arms to unfold at a large angle or fold back for storage. This expands the working height and coverage of the dust suppression nozzle, effectively improving dust suppression efficiency. Furthermore, the boom system can be compactly folded in non-operating states, significantly reducing the overall size of the equipment. This solves the problems of traditional fixed high-tower equipment, such as difficulty in movement and large storage space requirements, significantly enhancing flexibility and practicality.

[0015] (2) By employing a drive structure in which a motor drives a worm gear, which in turn drives a worm wheel fixedly connected to the first rotating arm, the inherent self-locking characteristic of the worm gear transmission pair allows the rotating arm to be reliably locked at any desired angle without the need for an additional braking device. This effectively prevents the boom from accidentally falling or swinging due to the reaction force of the water flow or vibration during nozzle operation, ensuring the stability of the spray direction and the safety of the operation process. At the same time, the structure is compact and the control is precise.

[0016] (3) Rotation grooves are opened on the first rotating arm and the second rotating arm to provide sufficient space for the connecting ring to move.

[0017] (4) By installing multiple self-locking casters at the bottom of the base plate and adding a push handle at the rear, a convenient mobility system is formed. This allows a single person to easily move long distances and flexibly turn the equipment even when it is fully loaded, quickly switching between different work points on the construction site. The self-locking function of the casters ensures that the equipment remains stable when working in a fixed position, achieving a balance between mobility flexibility and operational stability.

[0018] (5) When the equipment is stored, the sleepers can effectively prevent the first rotating arm and other components from being subjected to force due to being suspended, prevent structural deformation or accidental damage caused by long-term storage, and improve the protection and durability of the equipment.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 The illustrated mobile foldable environmentally friendly dust suppression device for construction engineering includes a base plate 1, such as... Figure 1 As shown, a water tank 4 and a water pump 10 are connected to the top of the base plate 1. A base 2 is rotatably connected to the left side of the base plate 1. A mounting bracket 7 is connected to the top of the base 2. A first rotating arm 12 is rotatably connected to the inner wall of the mounting bracket 7. The mounting bracket 7 is connected to a drive structure to realize the vertical rotation of the first rotating arm 12. Figure 2 As shown, a connecting plate 17 is connected to the left end of the first rotating arm 12, and a second rotating arm 13 is rotatably connected to the inner wall of the connecting plate 17, as follows. Figure 1 The end of the second rotating arm 13 is connected to a dust suppression nozzle 11. The water pump 10 is connected to the dust suppression nozzle 11 and the water tank 4 through the connecting pipe 6. The first rotating arm 12 and the second rotating arm 13 are connected to an unfolding structure to realize the folding and unfolding of the arm.

[0025] like Figure 2 As shown, the unfolding structure includes a cylinder 16, a first rotating arm 12 with a second storage slot 15, and a second rotating arm 13 with a first storage slot 14. A connecting ring 18 is rotatably connected to the inner walls of the first and second storage slots 14 and 15. The cylinder 16 is rotatably connected to the inner wall of the second storage slot 15. A push plate 19 is connected to the output end of the cylinder 16, and the push plate 19 is rotatably connected to the connecting ring 18. During unfolding, the cylinder 16 pushes the push plate 19 to rotate counterclockwise around its axis on the first rotating arm 12, and the connecting ring 18 pushes the second rotating arm 13 to unfold synchronously, thereby achieving smooth unfolding of the boom and precise angle control, while also expanding the rotation angle of the second rotating arm 13.

[0026] like Figure 3 As shown, the drive structure includes a motor 8 connected to the top of the mounting bracket 7. A worm gear 9 is connected to the output end of the motor 8, and the bottom of the worm gear 9 is rotatably connected to the base 2. A worm wheel 21 is connected to the first rotating arm 12, and the worm wheel 21 meshes with the worm gear 9. An opening is provided on the top left side of the mounting bracket 7 to ensure rotational space for the first rotating arm 12. This drive structure utilizes the self-locking characteristic of the worm gear to reliably lock the angle while adjusting the vertical angle of the first rotating arm 12, preventing deviation during operation.

[0027] like Figure 2 As shown, the first rotating arm 12 and the second rotating arm 13 are respectively provided with rotating grooves 20, which provide sufficient space for the movement of the connecting ring 18.

[0028] like Figure 1 As shown, the bottom of the base plate 1 is connected to several self-locking casters 3, and the right side is connected to a push handle 5, which together form a convenient moving system, enabling the equipment to be moved easily and positioned accurately.

[0029] like Figure 1 As shown, a sleeper 22 is connected to the top of the base plate 1. When the equipment is folded and stored, the sleeper 22 provides support for the first rotating arm 12, preventing it from being suspended in the air and protecting the equipment structure.

[0030] The specific implementation process is as follows:

[0031] The operator first moves the device to the designated work position using the push handle 5 and the self-locking casters 3 at the bottom of the base plate 1. Then, the motor 8 is started, driving the worm gear 9 to rotate. This, through the meshing worm wheel 21, drives the first rotating arm 12 to extend vertically, reliably locking the angle using the self-locking characteristic of the worm gear transmission. Next, the cylinder 16 is activated to push the push plate 19, simultaneously extending the first rotating arm 12 and the second rotating arm 13 via the connecting ring 18, raising the dust suppression nozzle 11 to the optimal working height. The water pump 10 delivers water from the water tank 4 to the dust suppression nozzle 11 via the connecting pipe 6, forming an atomized water curtain for dust suppression. After the operation is completed, the cylinder 16 retracts, folding the boom system back up. The lower end of the first rotating arm 12 is securely supported on the sleeper 22. Finally, the casters 3 are locked, allowing the equipment to be moved or stored.
