Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a dust reduction device for building construction. Background Art

[0002] During the urban construction process, construction sites often generate a lot of dust due to construction activities. This dust will have a negative impact on the surrounding environment and the health of practitioners. In order to solve this problem, construction sites need to be equipped with special dust reduction devices. These devices can reduce dust generation and diffusion in a variety of ways to ensure the air quality of the construction site.

[0003] The Chinese patent publication number is CN217287731U. It discloses a construction dust reduction device, which includes a box body, a water storage chamber is arranged inside the box body; two fixed blocks are fixedly connected to one side of the box body, and support rods are fixedly connected to the two fixed blocks. The utility model can realize that the device can spray the construction site well to achieve the effect of dust reduction by setting a water inlet mechanism and a spray mechanism, and can realize that the sliding block can be conveniently driven up and down by pulling the wheel chain by setting a zipper mechanism, so as to change the height of the spray to adapt to construction operations at different heights.

[0004] With regard to the above-mentioned related technologies, the device has some shortcomings. In actual use, the height of the spray is changed to adapt to construction operations at different heights. However, the dust reduction water sprayed by the device cannot be recycled, but falls directly on the ground of the construction site. This practice leads to low water utilization, waste of water resources, and correspondingly high use costs. Therefore, it is necessary to provide a construction dust reduction device to solve the above-mentioned technical problems. Utility Model Content

[0031] The conduit 21 is rotatably connected to the movable tube 16 through a sealed bearing installed at the top thereof, a dust suppression tube 8 is fixedly installed at the top of the movable tube 16, and the dust suppression tube 8 is connected to the inside of the movable tube 16, the bottom of another fixed plate 14 is fixedly connected to the driving end of the electric telescopic rod 10, and a plurality of atomizing nozzles 9 are fixedly installed on the outer wall of the dust suppression tube 8;

[0032] An annular collecting box 4 is fixedly installed on the upper side of the outer surface of the water tank 2, and a plurality of reflux holes 3 are opened above the connection between the outer surface of the electric flatbed vehicle body 1 and the annular collecting box 4. A water supply pipe 6 is fixedly installed on one side of the top of the electric flatbed vehicle body 1, and a drainage pipe is fixedly installed on the lower side of the front side of the water tank 2.

[0033] A motor 19 is fixedly mounted on the top of the other fixed plate 14 , a second gear 18 is fixedly mounted on the driving end of the motor 19 , a first gear 17 is fixedly sleeved on the outer wall of the movable tube 16 , and the first gear 17 is meshed with the second gear 18 .

[0034] In one of the embodiments, a filter screen 11 is fixedly installed between the interior of the annular collecting box 4 and the upper outer surface of the water storage tank 2, and a plurality of triangular support blocks are fixedly installed between the bottom of the annular collecting box 4 and the surface of the water storage tank 2. The triangular support blocks are arranged to improve the stability of the connection between the annular collecting box 4 and the water storage tank 2.

[0035] In one preferred embodiment, the connecting pipe 7 is made of a soft material to facilitate adjustment of the height of the device.

[0036] In one of the embodiments, a battery 22 is fixedly installed on one side of the front of the water tank 2, so that the device can be powered independently. When in use, no external power supply is required, which improves the convenience of using the device.

[0037] In one of the preferred embodiments, the bottom of a fixed plate 14 is located on the outside of the water pump 12 and a first protective box 13 is fixedly installed thereon, and the top of another fixed plate 14 is located on the outside of the motor 19 and a second protective box 20 is fixedly installed thereon, thereby effectively protecting the water pump 12 and the motor 19.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to the battery 22 and the control switch when in use. The specific structure of the electric flatbed vehicle body 1 can refer to the prior art, which can be easily implemented by those skilled in the art. When the device is in use, the electric flatbed vehicle body 1 drives the device to move autonomously along a specific route at the construction site. The device can fill the water source into the water storage tank 2 through the water filling pipe 6 in advance, and can directly allow the water source to enter the bottom of the filter screen 11 inside the annular collection box 4 through the reflux hole 3, thereby increasing the storage water capacity of the device. During the movement of the electric flatbed vehicle body 1 at the construction site, the device starts working by controlling the water pump 12 and the electric telescopic rod 10 through the switch. The driving end of the electric telescopic rod 10 can drive the fixed plate 14 on the left to move vertically, and the movement of the fixed plate 14 drives the mounting block 15 to move. The movement of the mounting block 15 drives the movable pipe 16 to move through the guide tube 21, and the movement of the movable pipe 16 drives the dust suppression pipe 8 to move. The atomizing nozzle 9 moves with the dust suppression pipe 8. Therefore, the water spraying height of the device can be changed by driving the electric telescopic rod 10, so that the device can adapt to construction operations at different heights. After the water pump 12 is started, the water source inside the water tank 2 will be pumped out through the passage formed by the water tank 2, the connecting pipe 7 and the water pumping pipe 5, and the water source will be input into the dust suppression pipe 8 through the movable pipe 16, and finally sprayed out through the atomizing nozzle 9 to perform dust reduction operations around the device. Most of the water will fall into the inside of the annular collecting box 4 together with the dust. The filter screen 11 inside the annular collecting box 4 will filter the recovered water and retain the dust on the upper surface of the filter screen 11 to prevent dust from entering the inside of the device and clogging the pipeline. The water will pass through the mesh on the filter screen 11 and enter the bottom of the filter screen 11, and finally flow back to the inside of the water tank 2 through the reflux hole 3 to continue to supply the device for dust reduction, thereby realizing the effective recycling of water for dust reduction, improving the utilization rate of water, and reducing the waste of water resources and the use cost of the device.

[0039] During use of the device, the motor 19 can be controlled by a switch to start working. The driving end of the motor 19 drives the second gear 18 to rotate. Through the meshing of the second gear 18 and the first gear 17, the first gear 17 drives the movable tube 16 to rotate. The rotation of the movable tube 16 drives the dust reduction tube 8 to rotate. The rotation of the dust reduction tube 8 drives the atomizing nozzle 9 to rotate, thereby increasing the spray range of the atomizing nozzle 9 and improving the dust reduction effect of the device. The annular collecting box 4 adopts an annular structure with a wide coverage range. The rotation effect of the dust reduction tube 8 does not affect the recovery efficiency of the dust reduction water, and is highly practical.

[0040] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
