Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology at construction sites, specifically a mobile water spraying dust suppression device for construction sites. Background Technology

[0002] In order to effectively control dust at construction sites and reduce air pollution, most existing dust control devices spray water into the air to suppress dust at construction sites and prevent dust from flying around and affecting the surrounding air environment.

[0003] Many existing construction sites control dust using traditional sprayers. However, due to the large size of the construction site, it is impossible to carry out dust suppression on a large scale in a timely manner. Furthermore, the spraying range and angle are limited, failing to achieve the desired spraying effect. Therefore, a mobile water spraying dust suppression device for construction sites is proposed. Utility Model Content

A water inlet is connected to one side of the top of the water storage tank, and a sealing plug is slidably disposed at the top of the water inlet. Two support plates are connected to the top of the water storage tank, and a cylinder is rotatably disposed between the two support plates. A conical cylinder is connected to one end of the cylinder, and a first electric actuator is connected to one side of the conical cylinder.

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a technical solution, including a support frame 1, a water storage tank 2 slidably disposed inside the support frame 1, and a water pump and a pressurizing pump disposed inside the water storage tank 2. A water inlet 3 is connected to one side of the top of the water storage tank 2, and a sealing plug 4 is slidably disposed at the top of the water inlet 3. Two support plates 5 are connected to the top of the water storage tank 2, and a cylinder 6 is rotatably disposed between the two support plates 5. A conical cylinder 61 is connected to one end of the cylinder 6, and a first electric push rod 62 is connected to one side of the conical cylinder 61. An mounting plate 7 is connected to the top of the water storage tank 2, and a hydraulic cylinder 8 is rotatably disposed between the top of the mounting plate 7 and the conical cylinder 61. Two traction arms 9 are connected to one side of the support frame 1, and a connecting block 10 is connected to one end of the supporting frame 1. A traction block 11 is connected to one side of the connecting block 10, and a bolt hole 12 is opened at the top of the traction block 11. A spraying mechanism 13 is slidably disposed inside the cylinder 6.

[0021] The spraying mechanism 13 includes a spraying cylinder 132 slidably disposed inside the cylinder 6. A connecting frame 131 is connected to one side of the spraying cylinder 132, and one side of the connecting frame 131 is connected to the output end of the first electric push rod 62. A second electric push rod 133 is connected inside the connecting frame 131, and the output end of the second electric push rod 133 extends into the spraying cylinder 132 and is connected to a push plate 134. Four arc-shaped opening and closing plates 135 are rotatably disposed on the surface of the spraying cylinder 132. Torsion springs 136 are connected to the arc-shaped opening and closing plates 135 and the rotating part of the spraying cylinder 132. Multiple spray heads 137 are connected to one end and the surface of the spraying cylinder 132. A push plate 137 is connected to one side of the surface of the spraying cylinder 132. The first connection port 138 is provided, which allows the spray cylinder 132 to be slidably disposed inside the cylinder 6 and connected to the output end of the first electric actuator 62 through the connecting bracket 131. This allows the spray cylinder 132 to extend and retract flexibly within the cylinder 6, thereby adjusting the spraying range as needed. By controlling the extension and retraction of the second electric actuator 133, the position of the push plate 134 within the spray cylinder 132 can be precisely adjusted, thereby controlling the flow rate of the liquid within the spray cylinder 132 and achieving precise spray volume control. The four arc-shaped opening and closing plates 135 rotatably disposed on the surface of the spray cylinder 132 can be opened during spraying to allow the liquid to spray out, and also help protect the spray head 137 from damage by the external environment.

[0022] The spray nozzles 137 on the surface of the spray cylinder 132 are set at an inclined angle. The purpose of the inclined spray angle is to allow the sprayed liquid to cover a wider area. Compared with vertical spraying, inclined spraying can increase the horizontal diffusion of the liquid, thereby reducing the spray blind zone and improving the spraying efficiency.

[0023] Two reinforcing arms 14 are connected between the two traction arms 9. The function of the reinforcing arms 14 is to serve as an additional support structure, which can significantly improve the overall rigidity and stability between the traction arms 9. When subjected to traction force or external load, the reinforcing arms 14 can distribute stress and reduce the deformation and vibration of the traction arms 9, thereby ensuring the stability and reliability of the device during operation.

[0024] Visual scales 15 are connected to both sides of the water tank 2. Corresponding to the visual scales 15, the support frame 1 has through slots 16 on both sides. The purpose of the visual scales 15 is to allow users to directly observe the water level in the water tank 2 without opening the water tank or performing other complicated operations.

[0025] The bottom of the support frame 1 is connected to four casters 17, which are arranged in a rectangular shape. This high degree of flexibility allows the device to easily adapt to different working environments and layouts, making it convenient for users to adjust the position of the device as needed.

[0026] A second connection port 18 is provided on one side of the top of the water storage tank 2, and the second connection port 18 is located directly below the first connection port 138. Both pump bodies are connected to the second connection port. Its function is to facilitate the operator to connect the first and second connection ports through the pipe.

[0027] Working principle: First, open the sealing plug 4 and fill the water tank 2 with water through the water inlet 3. Observe the visual scale 15 to confirm the water level. Connect the first connection port 138 and the second connection port 18 with a water pipe. Then, reverse the vehicle in front of the device and use the traction arm 9 to connect the vehicle to move the device to the target area. Start the hydraulic cylinder 8 to adjust the spray angle. When large-area spraying is required, start the water pump and pressurization pump inside the water tank 2. Then start the first electric actuator 62. The first electric actuator 62 pushes the spraying mechanism 13 forward as a whole. Due to the torsion of the arc-shaped opening and closing plate 135... The spring 136 is in the open state, but initially the cylinder 6 holds the arc-shaped opening and closing plate 135. When it reaches the predetermined position, the kinetic energy of the torsion spring 136 is released, opening the arc-shaped opening and closing plate 135. Then the second electric push rod 133 is activated, which drives the push plate 134 to move backward, making room for the spray head 137 on the surface of the spray cylinder 132, allowing more spray heads 137 to participate in spraying, thereby increasing the spraying area. When only a small area needs to be sprayed, the first electric push rod 62 and the second electric push rod 133 can be activated in reverse.
