Description

Technical Field

[0001] This utility model relates to the field of construction dust suppression technology, specifically a dust suppression device for civil construction. Background Technology

[0002] During civil engineering construction, construction work on the ground inevitably generates a certain amount of dust, which pollutes the construction site. Therefore, dust suppression devices are needed to reduce the amount of dust at the construction site.

[0003] Chinese patent CN215876689U discloses a dust suppression device for civil construction. It connects a water pipe for dust suppression to the upper part of an inlet pipe, allowing water to enter a storage tank. A control box controls a suction pump, drawing the water through a guide pipe into a three-way connecting pipe, which then delivers it to connecting hoses and spray pipes, forming a mist that is sprayed from nozzles to suppress dust. Additionally, the device controls the lifting of a hydraulic jack to raise and lower an extension rod, thereby changing the height of the crossbar and movable boom to meet dust suppression needs at different locations. The device can also adjust the angle of inclination between the movable boom and the crossbar according to the actual location, improving dust suppression efficiency.

[0004] While the aforementioned solutions utilize liftable water spray pipes to achieve dust suppression at different heights, the integrated spray structure with the vehicle body limits its application. This means the spray position can only be adjusted as the vehicle moves, resulting in low efficiency as only a single area can be sprayed at a time. Therefore, we provide a dust suppression device for civil construction to address these issues. Utility Model Content

[0029] like Figure 1-3 As shown, this utility model provides a technical solution: a dust suppression device for civil construction, including a vehicle body 1, an annular pipe 10, a liquid supply component and multiple spraying components.

[0030] The vehicle body 1 is equipped with a water tank 2, which has a water inlet pipe that can inject clean water into the water tank 2. The vehicle body 1 is also equipped with wheels and a push handle, which allows the vehicle body 1 to move on the ground.

[0031] Multiple spraying components are installed on the vehicle body 1, including a storage box 6. A support screw 7 is slidably connected to the storage box 6. A fixing seat 8 is fixedly connected to the support screw 7. A sprayer 9 is hinged to the fixing seat 8. The sprayer 9 is a hollow tube with a nozzle on its upper surface.

[0032] The storage box 6 is equipped with a height adjustment component for adjusting the extension length of the support screw 7.

[0033] The rotating shaft 20 is designed with a screw block, which can drive the rotating shaft 20 to rotate. Under the action of the two bevel gears 21, the adjusting screw 18 rotates inside the storage box 6, thereby adjusting the position of the support screw 7 on the adjusting screw 18, and thus adjusting the extension height of the support screw 7 from inside the storage box 6.

[0034] A guide block 19 is fixedly connected to the support screw 7, and the guide block 19 is slidably connected inside the storage box 6. The guide block 19 is used to guide the movement of the support screw 7.

The multi-head connector 4 is connected to the annular pipe 10 through a pipe.

[0042] One end of the multi-head connector 4 has one interface, and the other end of the multi-head connector 4 has multiple interfaces, and each interface is designed with a valve. The multi-head connector 4 is used to transport water in the water tank 2 to each ring pipe 10 to complete the water supply to multiple spray components.
