Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention in engineering construction, in particular to an engineering construction dust prevention device. Background Technique

[0002] During the process of engineering construction, a large amount of dust is usually generated at the construction site, resulting in a poor environment at the construction site and the surrounding areas, affecting air quality and the physical health of personnel. In order to prevent the dust at the construction site from flying and spreading, a dust-proof net is usually fixedly installed around the construction site to prevent dust and dust from spreading outwards and avoid affecting the external environment of the construction site.

[0003] However, the dust prevention and suppression effect of relying solely on the dust-proof net is poor. For this reason, an engineering construction dust prevention device is proposed. For example, an engineering construction dust prevention device disclosed in the patent publication number CN218668805U solves the problem that dust and dust spread outwards and affect the external environment of the construction site by arranging water pipes and nozzles on the dust-proof net.

[0004] When the above patent is actually used, there are still certain drawbacks. When the dust-proof net is unfolded and retracted, four groups of telescopic rods need to be manually adjusted, so that the dust-proof net is inconvenient to unfold and retract, the dust-proof effect of water mist spraying is poor, and the practicability is low. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an engineering construction dust prevention device that can make the dust-proof net more convenient to unfold and retract, effectively improve the dust-proof effect of water mist spraying, and improve the practicability.

[0006] Technical Solution

[0007] To achieve the above object, the present utility model provides the following technical solution: An engineering building dust prevention device, comprising a bottom plate, a dust prevention mechanism and a retractable mechanism. The dust prevention mechanism includes a vertical pipe and a dust prevention net. The bottom end of the vertical pipe is fixedly connected to the top end of the bottom plate. The lower side of the outer wall of the vertical pipe is fixedly communicated with a butt joint pipe orifice. Two groups of shunt pipes are fixedly communicated with the vertical pipe symmetrically left and right. A plurality of rear atomizing nozzles are fixedly communicated with the outer wall of the rear side of the vertical pipe at equal intervals. Both the upper and lower ends of the dust prevention net are fixedly connected with horizontal pipes. The outer sides of the two groups of shunt pipes are both communicated and installed with conveying hoses. The output ends of the two groups of conveying hoses are respectively communicated with one side of the two groups of horizontal pipes. A plurality of front atomizing nozzles are fixedly communicated with the front ends of the two groups of horizontal pipes at equal intervals. The retractable mechanism includes two groups of movable collar rings, which are respectively slidably sleeved on the two groups of shunt pipes. Knob bolts are screwed on the two groups of movable collar rings, and the ends of the two groups of knob bolts are respectively tightened against the two groups of shunt pipes. T-shaped connecting plates are fixedly connected to the two groups of movable collar rings. Two groups of inner T-shaped columns are symmetrically fixedly arranged at the front ends of the two groups of T-shaped connecting plates. Transmission strip plates are rotatably sleeved on the four groups of inner T-shaped columns. Outer T-shaped columns are fixedly connected to the left and right sides of the rear ends of the two groups of horizontal pipes. The outer ends of the four groups of transmission strip plates are respectively rotatably sleeved on the four groups of outer T-shaped columns.

[0008] Preferably, both ends of the two groups of conveying hoses are fixedly communicated with threaded butt joints. The outer sides of the two groups of shunt pipes are fixedly communicated with water outlet butt joints. One side of each of the two groups of horizontal pipes is fixedly communicated with a water inlet butt joint. The four groups of threaded butt joints are respectively screwed and sleeved on the two groups of water outlet butt joints and the two groups of water inlet butt joints.

[0009] Preferably, two groups of threaded tie rods are screwed on the bottom plate symmetrically left and right. Knobs are fixedly arranged at the top ends of the two groups of threaded tie rods.

[0010] Preferably, plastic collar sleeves are fixedly arranged on the outer sides of the middle positions of the two groups of horizontal pipes.

[0011] Preferably, sliding sleeves are fixedly arranged on the arc inner walls of the two groups of plastic collar sleeves.

[0012] Preferably, anti-slip threads are arranged on the outer walls of the two groups of knob bolts.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When in use, place the device at an appropriate position on the construction site, make the front atomizing nozzle face the inner side of the construction site, first unfold the dust-proof net. When unfolding, loosen the knob bolt, and then slide the movable collar outward along the shunt pipe, so that the movable collar drives the T-shaped connecting plate to slide outward. Since both sides of the transmission strip plate are rotatably sleeved with the outer T-shaped column and the inner T-shaped column respectively, the T-shaped connecting plate pushes the two horizontal pipes to move axially outward along the vertical pipe through the transmission strip plate, so that the horizontal pipes drive the dust-proof net to unfold. After the dust-proof net is unfolded, tighten the knob bolt to fix the position of the movable collar. Then connect the butt joint pipe opening to the water pipe, use the water pump to supply water to the vertical pipe, and the vertical pipe conveys the water to the rear atomizing nozzle for atomizing spraying. And the water is also conveyed to the horizontal pipes through the shunt pipe and the conveying hose, so that the water is atomized and sprayed through the front atomizing nozzle, realizing the dust-proof treatment of the construction site. By sliding the movable collar left and right to adjust, the dust-proof net can be unfolded and retracted, so that it is more convenient to unfold and retract the dust-proof net. By spraying the construction site back and forth and spraying on both the upper and lower sides of the dust-proof net, the dust-proof effect of the water mist spraying can be effectively improved, and the practicability is improved.

When in use, place the device at an appropriate position at the construction site, make the front atomizing nozzles 14 face the inside of the construction site. First, unfold the dust-proof net 4. When unfolding, loosen the knob bolts 9, and then slide the movable collar rings 8 outward along the shunt pipes 7, so that the movable collar rings 8 drive the T-shaped connecting plates 10 to slide outward. Since both sides of the transmission strip plates 12 are rotatably sleeved with the outer T-shaped columns 6 and the inner T-shaped columns 11 respectively, the T-shaped connecting plates 10 push the two groups of horizontal pipes 5 to move outward along the axial direction of the vertical pipe 2 through the transmission strip plates 12, so that the horizontal pipes 5 drive the dust-proof net 4 to unfold.

Then connect the butt joint pipe orifice 3 to a water pipe, and use a water pump to supply water to the vertical pipe 2. The vertical pipe 2 conveys the water to the rear atomizing nozzles 13 for atomizing spraying. And the water is also conveyed to the horizontal pipes 5 through the shunt pipes 7 and the conveying hoses 15, so that the water is atomized and sprayed through the front atomizing nozzles 14, realizing the dust-proof treatment of the construction site.

[0025] Two groups of threaded tie rods 19 are symmetrically screwed on the left and right on the base plate 1. Wrench handles 20 are fixedly arranged at the tops of the two groups of threaded tie rods 19. By providing the threaded tie rods 19 and the wrench handles 20, during use, after the base plate 1 is placed at an appropriate position, the threaded tie rods 19 are screwed by the wrench handles 20 to make the threaded tie rods 19 penetrate into the ground, so that the base plate 1 can be placed and fixed, thereby improving the stability of the device and avoiding tipping over.

[0026] Plastic sleeves 21 are fixedly arranged on the outer sides of the middle positions of the two groups of horizontal pipes 5. By providing the plastic sleeves 21, when the dust-proof net 4 is unfolded through the horizontal pipes 5, the plastic sleeves 21 can be sleeved on the vertical pipes 2 first to support the horizontal pipes 5, thereby improving the stability when the dust-proof net 4 is unfolded.

[0027] Sliding sleeves 22 are fixedly arranged on the arc inner walls of the two groups of plastic sleeves 21. By providing the sliding sleeves 22, the plastic sleeves 21 can slide more smoothly on the vertical pipes 2.

[0028] Anti-slip threads 23 are arranged on the outer walls of the two groups of knob bolts 9. By providing the anti-slip threads 23, the situation of hand slipping can be prevented when the knob bolts 9 are screwed.

[0029] An engineering construction dust prevention device of the present utility model, its working principle is as follows. When in use, place the device at an appropriate position on the construction site, make the front atomizing nozzle 14 face the inside of the construction site. After placing it at an appropriate position, turn the screw rod 19 through the turning handle 20 to make the screw rod 19 penetrate into the ground, so that the bottom plate 1 is placed and fixed. First, unfold the dust-proof net 4. When unfolding, first put the plastic collar 21 on the vertical pipe 2 to support the horizontal pipe 5. Then loosen the knob bolt 9, and then slide the adjustable collar 8 outward along the shunt pipe 7, so that the adjustable collar 8 drives the T-shaped connecting plate 10 to slide outward. Since both sides of the transmission strip 12 are rotatably sleeved with the outer T-shaped column 6 and the inner T-shaped column 11 respectively, the T-shaped connecting plate 10 pushes the two groups of horizontal pipes 5 to move axially outward along the vertical pipe 2 through the transmission strip 12, so that the horizontal pipes 5 drive the dust-proof net 4 to unfold. After the dust-proof net 4 is unfolded, tighten the knob bolt 9 to fix the position of the adjustable collar 8. Then connect the butt joint nozzle 3 to the water pipe, use the water pump to supply water to the vertical pipe 2, and the vertical pipe 2 conveys the water to the rear atomizing nozzle 13 for atomizing spraying. And the water is also conveyed into the horizontal pipes 5 through the shunt pipe 7 and the conveying hose 15, so that the water is atomized and sprayed through the front atomizing nozzle 14, realizing the dust prevention treatment of the construction site.
