Description

Technical Field

[0001] This invention relates to the technical field of dust suppression at construction sites, and in particular to a dust suppression device for green construction at construction sites. Background Technology

[0002] During construction, activities such as earthwork excavation, material stockpiling, and building material loading and unloading generate a large amount of dust particles. This dust can directly enter the human body, posing a significant health hazard and negatively impacting air quality by reducing visibility and affecting the air quality index. Therefore, dust suppression equipment is used in conjunction with construction site operations. Fog cannons are commonly used for dust suppression. Fog cannons produce fine and dense water mist particles that can spread over a wide area. Combined with multi-angle rotation, this achieves comprehensive coverage of different areas of the construction site. Thus, a green dust suppression device for construction sites is needed.

[0003] Existing dust suppression equipment used for green construction at construction sites typically uses atomizing nozzles installed at fixed angles. These nozzles maintain a constant angle and cannot be adjusted to vary the spray range based on the size of the area being used, which can easily lead to poor dust suppression performance. Summary of the Invention

[0004] The purpose of this invention is to provide a dust suppression device for green construction sites, in order to solve the problem mentioned in the background art that existing dust suppression devices for green construction sites are all equipped with atomizing nozzles at a fixed angle. The atomizing nozzles always maintain the same angle, and the atomizing spray range cannot be adjusted according to the size of the area to be used, which easily leads to poor dust suppression effect of the fog cannon.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for green construction at a construction site, comprising a housing, a shell fixedly installed on one side of the upper surface of the housing, a connecting shaft passing through and bearing the inner ring of the shell, a support plate fixedly installed at one end of the connecting shaft passing through the shell, a support frame fixedly installed on the upper surface of the support plate, and a cylinder rotatably connected to both ends of the upper part of the support frame. A second fixing pipe is fixedly installed on the outer ring of one end of the cylinder, and threaded interfaces are evenly spaced on the outer ring surface of the second fixing pipe. A connector is threaded to one end of the threaded interface, and a spherical groove is formed on the inner side of one end of the connector. A rotatable hollow sphere is fitted into the inner ring of the spherical groove, and a water inlet hole is formed on the surface of the hollow sphere. The hollow sphere has a sealing ring fixedly fitted around its outer ring. A second atomizing nozzle is fixedly connected to one end of the hollow sphere. A connecting ring is fixedly fitted around the outer ring of the second atomizing nozzle. A fixing ring is fixedly installed on one side of the connecting ring.

A second water inlet pipe is fixedly connected to one side surface of the second fixing pipe. A fixing frame is fixedly installed around the inner ring of the cylinder. A fixing seat is welded to one end of the fixing frame. A second drive motor is fixedly installed on one side surface of the fixing seat. A threaded rod is fixedly connected to the output end of the second drive motor through the fixing seat. An internally threaded pipe is threadedly connected to one end of the threaded rod. An outer ring is fixedly fitted around the outer ring of the internally threaded pipe.

[0006] Preferably, a worm gear is fixedly fitted onto the outer ring of the connecting shaft, a worm is meshed with one side of the worm gear, a first drive motor is fixedly installed on one side of the outer wall of the housing, both ends of the worm are connected to the housing bearings, and one end of the worm is fixedly connected to the output end of the first drive motor. Preferably, a fixing block is fixedly installed on one side surface of the cylinder and the upper surface of the support frame, and the two sets of fixing blocks are rotatably connected to both ends of the hydraulic push rod.

[0007] Preferably, an air intake fan is fixedly installed on the inner ring of the air inlet of the cylinder by a mounting bracket, and a protective net is fixedly installed on one end of the air inlet of the cylinder.

[0008] Preferably, a first fixing pipe is fixedly installed on the inner ring of the other end of the cylinder, and a first atomizing nozzle is connected to the surface of the first fixing pipe at equal intervals. A first water inlet pipe that penetrates the cylinder is threaded to one side of the first fixing pipe.

[0009] Preferably, the water inlet hole of the hollow sphere corresponds to the water inlet of the connector, and the second atomizing nozzle and the first atomizing nozzle are staggered.

[0010] Preferably, one end of each connecting block is fixedly connected to the outer ring, and both ends of the threaded rod are provided with baffles to limit the stroke.

[0011] Preferably, a water tank is fixedly placed inside the housing, a high-pressure pump is connected to the outlet of the water tank via a flange, a flexible pipe is connected to the other side of the high-pressure pump via a flange, and one side of the flexible pipe is fixedly connected to the first inlet pipe and the second inlet pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By using a worm gear, worm shaft, and hydraulic push rod, the cylinder can be flexibly adjusted in terms of horizontal rotation and pitch angle, thereby achieving comprehensive coverage of different areas of the construction site.

[0013] By setting up the first and second atomizing nozzles, the first atomizing nozzle is installed at a fixed angle, which can ensure the uniformity of the inner ring spray and the stability of the range. Secondly, the second atomizing nozzle can be adjusted in angle through a hollow sphere. When rotated outward, the diameter range of diffusion is increased. When rotated inward, it works with the first atomizing nozzle in the inner ring to perform concentrated atomization spray, thereby increasing the atomization dust suppression effect of the first atomizing nozzle.

[0014] The second drive motor drives the threaded rod to rotate, which in turn causes the internal threaded tube to move. As the internal threaded tube moves, it drives the connecting frame to move as well. One end of the connecting frame is connected to the second atomizing nozzle through a fixing ring and a connecting ring. Under the push of the connecting frame, the second atomizing nozzle rotates to a certain extent through the hollow sphere at one end of the spherical groove, changing the spray range of the second atomizing nozzle and making corresponding adjustments according to the dust suppression area of ​​the construction site.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Please see Figure 1-8This invention provides a technical solution: a dust suppression device for green construction at a construction site, comprising a housing 1, a shell 2 fixedly installed on one side of the upper surface of the housing 1, a connecting shaft 3 passing through and bearing the inner ring of the shell 2, a support plate 7 fixedly installed at one end of the connecting shaft 3 passing through the shell 2, a support frame 8 fixedly installed on the upper surface of the support plate 7, a cylinder 9 rotatably connected to the upper two ends of the support frame 8, a second fixing pipe 17 fixedly installed on the outer ring of one end of the cylinder 9, threaded interfaces 18 evenly spaced on the outer ring surface of the second fixing pipe 17, a connector 19 threadedly connected to one end of the threaded interface 18, a spherical groove 20 opened on the inner side of one end of the connector 19, a rotatable hollow sphere 21 fitted into the inner ring of the spherical groove 20, a water inlet hole 22 opened on the surface of the hollow sphere 21, and a water inlet hole 22 opened on the outer ring of the hollow sphere 21. A sealing ring 23 is fixedly fitted onto the hollow sphere 21. One end of the hollow sphere 21 is fixedly connected to a second atomizing nozzle 24. A connecting ring 25 is fixedly fitted onto the outer ring of the second atomizing nozzle 24. A fixing ring 26 is fixedly installed on one side of the connecting ring 25. A connecting bracket 27 is rotatably connected to one end of the fixing ring 26. A connecting block 28 is rotatably connected to the other end of the connecting bracket 27. A second water inlet pipe 29 is fixedly connected to one side of the second fixing pipe 17. A fixing frame 30 is fixedly installed on the inner ring of the cylinder 9. A fixing seat 31 is welded to one end of the fixing frame 30. A second drive motor 32 is fixedly installed on one side of the fixing seat 31. A threaded rod 33 is fixedly connected to the output end of the second drive motor 32 through the fixing seat 31. An internal threaded pipe 34 is threadedly connected to one end of the threaded rod 33. An outer ring 35 is fixedly fitted onto the outer ring of the internal threaded pipe 34.

[0019] Furthermore, a worm gear 4 is fixedly fitted onto the outer ring of the connecting shaft 3. A worm 5 is meshed with one side of the worm gear 4. A first drive motor 6 is fixedly installed on one side of the outer wall of the housing 2. Both ends of the worm 5 are connected to the bearings of the housing 2, and one end of the worm 5 is fixedly connected to the output end of the first drive motor 6. Through the arrangement of the worm gear 4 and the worm 5, the first drive motor 6 drives the worm 5 to rotate on one side of the housing 2. When the worm 5 rotates, it drives the worm gear 4 to rotate. The worm gear 4 drives the support plate 7 to rotate through the connecting shaft 3. The support plate 7 drives the cylinder 9 to rotate through the support frame 8, which facilitates the horizontal angle adjustment of the cylinder 9. Furthermore, fixing blocks 10 are fixedly installed on one side surface of the cylinder 9 and the upper surface of the support frame 8. Both sets of fixing blocks 10 are rotatably connected to both ends of the hydraulic push rod 11. Through the setting of the hydraulic push rod 11, the output end of the hydraulic push rod 11 is rotatably connected to the fixing block 10 on the lower side of the cylinder 9. When the output end of the hydraulic push rod 11 extends or retracts, since the cylinder 9 and the support frame 8 are rotatably connected through the corresponding shaft, the cylinder 9 will be pushed to rotate and adjust the pitch angle at one end of the support frame 8.

[0020] Furthermore, an air intake fan 12 is fixedly installed on the inner ring of the air inlet of the cylinder 9 via a mounting bracket, and a protective net 13 is fixedly installed on one end of the air inlet of the cylinder 9. With the setting of the air intake fan 12 and the protective net 13, the air intake fan 12 is selected as an axial flow fan, which provides a larger air volume and the generated high-speed airflow can spray a wider range and better spray uniformity.

[0021] Furthermore, a first fixing pipe 14 is fixedly installed on the inner ring of the other end of the cylinder 9. A first atomizing nozzle 15 is connected to the surface of the first fixing pipe 14 at equal intervals. A first water inlet pipe 16 that penetrates the cylinder 9 is threaded to one side of the first fixing pipe 14. By setting the first atomizing nozzle 15, the first atomizing nozzle 15 is installed at a fixed angle on the inner ring of the cylinder 9 near the opening, which can ensure the uniformity of the inner ring spray and the stability of the range, and can accurately determine the spray angle.

[0022] Furthermore, the water inlet 22 of the hollow sphere 21 corresponds to the water inlet of the connector 19. The second atomizing nozzle 24 and the first atomizing nozzle 15 are staggered. Through the setting of the hollow sphere 21, the water inlet 22 on one side of the hollow sphere 21 corresponds to the connector 19. At the same time, the hollow sphere 21 can rotate at one end of the spherical groove 20. Moreover, under the action of the sealing ring 23, the side of the hollow sphere 21 without the water inlet 22 is sealed and fitted with the spherical groove 20. The distribution of the water inlet 22 can ensure that the hollow sphere 21 can still take in water after rotating at a certain angle.

[0023] Furthermore, one end of each connecting block 28 is fixedly connected to the outer ring 35, and both ends of the threaded rod 33 are provided with baffles that limit the stroke. Through the setting of the threaded rod 33, the baffle structure at both ends of the threaded rod 33 can limit the stroke of the inner threaded tube 34. One set of baffles is fixedly installed at the front end of the threaded rod 33, and the other set of baffles is sleeved and fixed at the position of the fitting fixing seat 31. By controlling the stroke of the inner threaded tube 34, the rotation angle of the second atomizing nozzle 24 can be controlled by the connecting frame 27.

[0024] Furthermore, a water tank 36 is fixedly placed inside the housing 1. A high-pressure pump 37 is connected to the outlet of the water tank 36 via a flange. A flexible pipe 38 is connected to the other side of the high-pressure pump 37 via a flange. One side of the flexible pipe 38 is fixedly connected to the first water inlet pipe 16 and the second water inlet pipe 29. Through the arrangement of the water tank 36 and the high-pressure pump 37, the water tank 36 can provide water for atomized spraying. The high-pressure pump 37 can deliver water to the flexible pipe 38, and then deliver it to the first fixed pipe 14 and the second fixed pipe 17 through the flexible pipe 38.

[0025] Working principle: First, the dust suppression equipment is moved to a general area on the construction site by the rollers at the bottom. Then, the first drive motor 6 drives the worm gear 5 to rotate, which in turn drives the worm wheel 4 and the connecting shaft 3 to rotate. This causes the connecting shaft 3 to drive the support frame 8 above the support plate 7 to rotate simultaneously. The support frame 8 can drive the cylinder 9 to rotate horizontally. When the cylinder 9 rotates to a suitable angle, the hydraulic push rod 11 pushes the cylinder 9 to adjust its pitch angle at one end of the support frame 8. After adjusting to the appropriate position, the high-pressure pump 37 delivers water from the water tank 36 to the flexible pipe 38, and then through the flexible pipe 38 to the first fixed pipe 14 and the second fixed pipe 17. The first atomizing nozzle 15 connected to the first fixed pipe 14 sprays atomized water at a fixed angle. The second fixed pipe 17... The second atomizing nozzle 24 connected to the second drive motor 32 drives the threaded rod 33 to rotate. Due to the threaded connection between the internal threaded tube 34 and the threaded rod 33, and the limitation created by the internal threaded tube 34 through the outer ring 35 and the connecting frame 27, when the threaded rod 33 rotates, the internal threaded tube 34 will not follow the rotation range, but will move at one end of the threaded rod 33 due to the threaded connection. At the same time, the internal threaded tube 34 drives the connecting block 28 on the outer ring of the outer ring 35 to move. The connecting block 28 pushes the connecting frame 27 to move. One end of the connecting frame 27 drives the second atomizing nozzle 24 to rotate through the fixing ring 26 and the connecting ring 25. The second atomizing nozzle 24 rotates at one end of the spherical groove 20 through the hollow sphere 21. The diameter range of the atomizing spray of the second atomizing nozzle 24 is adjusted according to the dust suppression range requirements of the construction site.

[0026] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
