Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction, and particularly to a dust reduction device for building construction. Background Art

[0002] During the process of building construction, in order to effectively reduce the generation of dust and thus protect the environment and the health of workers, construction teams usually take a series of dust reduction measures. These measures include, but are not limited to, using spraying equipment to moisten the ground to prevent dust from flying; installing dust-proof nets or enclosures to isolate the construction area and reduce the spread of dust to the surrounding environment; and regularly cleaning the construction site to ensure that the dust does not accumulate to an extent that affects the health of workers and construction safety.

[0003] Due to the different topographies and layouts of construction sites, some areas may form high-dust-emission areas due to factors such as the stacking of equipment and height differences of buildings. The spraying parts at fixed height positions cannot flexibly adapt to the layouts within a certain height range, making it difficult to carry out dust reduction operations. Moreover, the positions of the spraying parts are relatively fixed, so dust reduction operations can only be carried out in a limited area. For large-scale construction sites, it is difficult to achieve full coverage. Summary of the Invention

The inclined block II is arranged to squeeze the inclined block I, and the threaded holes are arranged to cooperate with the bidirectional screw for movement.

[0010] Preferably, the bidirectional screw is engaged with the threaded holes. A sliding groove is formed in the inner surface of the mounting seat near the inclined block II, and a sliding block is slidably connected in the sliding groove.

[0017] Working principle: When in use, first use the moving wheels to flexibly move the device to the target position. Subsequently, by adjusting the height of the mounting frame, the spraying member can be raised to an appropriate height, so as to effectively reduce dust at higher positions. The specific operation is as follows: Start the first motor to drive the rotation of the bidirectional screw on the side surface of the third mounting shaft, drive the sliding blocks connected thereto to move to both sides, and then make the inclined surface of the second inclined block and the first inclined block squeeze each other, realizing the height adjustment of the mounting frame, greatly improving the flexibility and adaptability of the device, and enabling it to meet the dust reduction requirements at different heights within a certain range. When facing a wider working area, after completing the height adjustment of the mounting frame, start the second motor to drive the rotating rod to rotate on the side surface of the first mounting shaft. A plurality of first bevel gears provided on the surface of the rotating rod rotate accordingly, and drive the corresponding second bevel gears to rotate. The rotation of the second bevel gear further drives the threaded rod to rotate on the upper surface of the second mounting shaft. The rotation of the threaded rod causes the moving block to slide on the inner wall of the fixed groove, thereby driving the guide plate to move towards the bottom plate. During this process, the guide columns move away from each other under the guiding action of the guide grooves, and then the spraying members connected to the guide columns move and separate from each other on the inner wall of the fixed frame, realizing the adjustment of the spacing between the spraying members, thereby effectively expanding the spraying range to better adapt to the wide working area. After the adjustment is completed, start the water pump to extract the water in the water storage tank and transport it to the flow dividing plate. The flow dividing plate evenly divides the water flow into multiple branches and transports it to each spraying member through the water conveying hoses. The spraying members convert the water into a mist and spray it out to conduct a comprehensive dust reduction operation on the construction site, effectively reducing the dust pollution.

[0018] (III) Beneficial effects

[0019] The present invention provides a dust reduction device for building construction. It has the following beneficial effects:

[0020] 1. By setting the rotating rod, spraying member, first bevel gear, second bevel gear, threaded rod, moving block, fixed groove, guide column, fixed frame, guide groove and mounting frame. A plurality of first bevel gears provided on the rotating rod rotate accordingly, and drive the corresponding second bevel gears to rotate. The rotation of the second bevel gear further drives the threaded rod to rotate on the upper surface of the second mounting shaft. The rotation of the threaded rod causes the moving block to slide on the inner wall of the fixed groove, thereby pushing the guide plate to move towards the bottom plate. During this process, the guide columns move away from each other under the guiding action of the guide grooves, and then the spraying members connected to the guide columns move and separate from each other on the inner wall of the fixed frame, realizing the adjustment of the spacing between the spraying members, thereby effectively expanding the spraying range.

[0021] 2. By setting up the mounting frame, spraying component, bidirectional screw, sliding block, second inclined block, first inclined block, motor 1 and third mounting shaft, motor 1 drives the bidirectional screw on the side surface of the third mounting shaft to rotate, thereby driving the connected sliding block to move to both sides. This action causes the inclined surfaces of the second inclined block and the first inclined block to squeeze each other, thereby realizing the height adjustment of the mounting frame. This design significantly improves the flexibility and adaptability of the device. Description of the Drawings
