Description

Technical Field

[0001] The invention relates to the technical field of spray dust reduction equipment, and in particular to a dust reduction device for construction and civil engineering. Background Art

[0002] In the field of construction and civil engineering, the dust problem generated during the construction process has always been a major problem that has troubled construction units and environmental protection departments. In cities, places near construction areas can obviously be found to have more traces of dust than other non-construction areas. Dust not only harms the health of workers on the construction site, but also pollutes the surrounding environment, affects air quality, and may even cause health problems such as respiratory diseases. Dust generated by construction has become a major obstacle to urban environmental protection.

[0003] Traditional dust reduction methods mainly include water sprinkling and covering. Water sprinkling is to sprinkle water on the construction area manually or mechanically to moisten and settle the dust particles. However, this method has problems such as waste of water resources, uneven water sprinkling, and limited dust reduction effect. Covering dust reduction is to reduce the generation of dust by laying dust-proof nets or dust-proof cloths and other coverings in the construction area. Although this method can reduce dust to a certain extent, the laying and removal of the covering requires a lot of manpower and material resources, and is easily affected by weather and human factors during use, and the dust reduction effect is unstable.

[0004] With the advancement of science and technology and the improvement of environmental awareness, people have begun to explore more efficient and environmentally friendly dust reduction methods. Spray dust reduction technology, as a new type of dust reduction method, has gradually been applied in the field of construction and civil engineering. Fog cannon is a common spray dust reduction device, but the defect of the fog cannon is that the spray range cannot be adjusted at the nozzle of the fog cannon, and the dust reduction area can only be adjusted by moving the nozzle of the fog cannon. Moreover, the water mist sprayed by the fog cannon is not entirely water mist, but also contains a large amount of water droplets. The dust reduction effect of this part of water droplets is average, but if the construction workers enter the construction nozzle of the fog cannon, their clothes will be quickly wetted by these water droplets. Therefore, in most cases, the fog cannon is only suitable for wetting the construction area before construction to reduce dust, and is not suitable for dust reduction during the construction process. Summary of the invention

[0005] The present invention aims to provide a dust suppression device for building civil engineering to solve the problem of poor dust suppression effect during the existing construction site.

[0006] The present invention is achieved through the following technical solutions:

[0007] A dust reduction device for building civil engineering, comprising a base, a housing assembly, a spray dust reduction device, and an adjustment assembly disposed between the base and the spray dust reduction device. The adjustment assembly is used to adjust the spray dust reduction device in two directions of pitching and rotation. The spray dust reduction device includes a blowing assembly and a spray assembly. The housing assembly includes a cylindrical shell and a conical shell. The cylindrical shell and the conical shell are fixedly connected. A blowing assembly is fixedly arranged inside the cylindrical shell. A wind guiding retaining ring and an internal wind guiding shell are arranged inside the conical shell. The wind guiding retaining ring is fixed to the inner wall of the conical shell. A wind guiding shell support frame is fixed inside the conical shell. The internal wind guiding shell is slidably matched with the conical shell through the wind guiding shell support frame. In the extreme state where the internal wind guiding shell slides to the farthest position from the cylindrical shell, one end of the internal wind guiding shell close to the cylindrical shell overlaps with the wind guiding retaining ring. The inside of the internal wind guiding shell is a first wind guiding channel, and the space between the internal wind guiding shell and the conical shell is a second wind guiding channel. A spiral wind guiding plate is arranged in the second wind guiding channel.

[0008] In a possible design, the inner wall of the internal wind guiding shell is slidably controlled by the sliding hydraulic rod. The cylinder body of the sliding hydraulic rod is fixed to the inner wall of the conical shell through a cylinder body support, and the rod head of the telescopic rod of the sliding hydraulic rod is fixedly connected to the inner wall of the internal wind guiding shell through a rod head support. When the sliding hydraulic rod is shortened to the shortest state, the annular gap between the internal wind guiding shell and the wind guiding retaining ring reaches the maximum.

[0009] In a possible design, the spiral wind guiding plate is fixed to the inner wall of the conical shell. When the sliding hydraulic rod is shortened to the shortest state, the wind generated by the blowing assembly enters the second wind guiding channel from the annular gap and is sprayed out in a rotating and diffusing state from the nozzle under the influence of the spiral wind guiding plate in the second wind guiding channel.

[0010] In a possible design, an annular water supply pipe is fixed at the nozzle of the conical shell. A plurality of nozzles are annularly and evenly distributed on the annular water supply pipe. Each nozzle is rotatably connected to the annular water supply pipe. The annular water supply pipe and each nozzle are communicated through a water supply port. The annular water supply pipe is internally supplied with water through a water supply pipe. The water supplied from the water supply pipe enters the annular water supply pipe and then is sprayed out atomized from each nozzle.

[0011] In a possible design, the nozzle is connected to the internal wind guiding shell through an elastic pull rope. The elastic pull rope passes through a rope winding seat fixed on the conical shell. Spray holes are provided on the internal wind guiding shell. When the sliding hydraulic rod is in the maximum extended state, the nozzle is aligned with the spray holes, and the water mist sprayed from the nozzle passes through the spray holes and reaches the nozzle of the internal wind guiding shell.

[0012] In a possible design, the blowing component includes a fan motor and a fan. The fan motor is fixed to the cylindrical shell, and a fan is fixed to the motor shaft of the fan motor.

[0013] In a possible design, the adjusting component includes a pitch control component and a swing control component. The pitch control component includes a pitch hydraulic rod. One end of the cylinder body of the pitch hydraulic rod is hinged to the hinge seat of the seat body, and the rod head of the telescopic rod of the pitch hydraulic rod is hinged to the hinge seat of the shell. The hinge seat of the shell is fixed to the conical shell. Two coaxial fixed shafts are fixed on both sides of the cylindrical shell. Both sides of the cylindrical shell are rotationally connected to the tops of two support columns through the two fixed shafts. The bottom end of each support column is fixed on a rotating base.

[0014] In a possible design, the swing control component includes the rotating base, a rotation control motor, and a motor fixing bracket. The rotating base is rotationally matched with the cylindrical shell. The motor fixing bracket is fixed inside the cylindrical shell. The body of the rotation control motor is fixed on the motor fixing bracket, and the motor shaft of the rotation control motor is fixed to the central position of the rotating base.

[0015] In a possible design, the spray head is an adjustable-angle spray head. The spray head is fixed on a rotating ring. The rotating ring is rotationally matched with the spray pipe. A rotating impact plate is arranged inside the spray pipe. The rotating impact plate controls the water flow to drive the rotating ring to rotate, thereby controlling the rotation of the spray head, and can adjust the spray direction according to needs to ensure that the dust suppression range covers the entire construction area.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] By changing the design of the housing assembly, the present invention can achieve two modes of diffusion dust suppression and convergence dust suppression. During diffusion dust suppression, the dust suppression range is large and the wind force is low, which is very suitable for dust suppression operations during construction. During convergence, the wind force is strong and the coverage distance is far, and large-scale dust suppression operations can be achieved, with diverse functions. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0026] Embodiment, as Figures 1 to 5 shown, this embodiment includes a base 1, a housing assembly, a spray dust suppression device, and an adjustment assembly disposed between the base 1 and the spray dust suppression device. The adjustment assembly is used to adjust the spray dust suppression device in two directions of pitching and rotation. The spray dust suppression device includes a blowing assembly and a spray assembly;

[0027] The housing assembly is composed of a cylindrical shell 2 and a conical shell 3 with a partially conical shape. The cylindrical shell 2 and the conical shell 3 are detachably and fixedly connected. A blowing assembly is fixedly arranged inside the cylindrical shell 2. Inside the conical shell 3, there are a wind guiding retaining ring 301 and an internal wind guiding shell 304. The wind guiding retaining ring 301 is fixed to the inner wall of the conical shell 3. A wind guiding shell support frame 306 is fixed inside the conical shell 3. The internal wind guiding shell 304 is slidably engaged with the conical shell 3 through the wind guiding shell support frame 306. In the extreme state where the internal wind guiding shell 304 slides to the farthest position from the cylindrical shell 2, one end of the internal wind guiding shell 304 close to the cylindrical shell 2 overlaps with the wind guiding retaining ring 301. In this state, the wind generated from the cylindrical shell 2 will all pass through the internal wind guiding shell 304 and then be ejected from the nozzle of the internal wind guiding shell 304. In this state, the spray dust suppression device realizes long-distance and small-range spray dust suppression, which is commonly used in large open-air construction sites for wetting the construction area before construction to achieve a preventive effect.

[0028] In this embodiment, the inner wall of the internal wind guiding shell 304 is slidably controlled by the sliding hydraulic rod 13. The cylinder body of the sliding hydraulic rod 13 is fixed to the inner wall of the conical shell 3 through a cylinder body support. The rod head of the telescopic rod of the sliding hydraulic rod 13 is fixedly connected to the inner wall of the internal wind guiding shell 304 through a rod head support. When the sliding hydraulic rod 13 is shortened to the shortest state, the annular gap between the internal wind guiding shell 304 and the wind guiding retaining ring 301 reaches the maximum.

[0029] Furthermore, the inside of the internal wind guiding shell 304 is a first wind guiding channel, and the space between the internal wind guiding shell 304 and the conical shell 3 is a second wind guiding channel. A spiral wind guiding plate 305 is arranged in the second wind guiding channel, and the spiral wind guiding plate 305 is fixed to the inner wall of the conical shell 3. When the sliding hydraulic rod 13 is shortened to the shortest state, the wind generated by the blowing assembly will enter the second wind guiding channel from the annular gap and be ejected from the nozzle in a rotating and diffusing state under the influence of the spiral wind guiding plate 305 in the second wind guiding channel, forming a diffused wind with a large range and a short distance.

[0030] In this embodiment, an annular water supply pipe 16 is fixed at the nozzle of the conical shell 3. A plurality of nozzles 17 are evenly distributed in a ring on the annular water supply pipe 16. Each nozzle 17 is rotatably connected to the annular water supply pipe 16. A water supply port 1601 is provided for communicating between the annular water supply pipe 16 and each nozzle 17. The annular water supply pipe 16 is supplied with water internally through a water supply pipe 6. The water supplied from the water supply pipe 6 enters the annular water supply pipe 16 and then is ejected in an atomized state from each nozzle 17.

[0031] During use, when the sliding hydraulic rod 13 is in the maximum extended state, only the first air guiding channel has air blown out. The water mist ejected from the nozzle 17 is affected by the strong wind in the first air guiding channel and is ejected as a slender spray column with a long spraying distance. When the sliding hydraulic rod 13 is in the maximum contracted state, the vast majority of the water mist ejected from the nozzle 17 is carried away by the diffused wind at the nozzle position of the second air guiding channel, forming a large-range dust suppression spraying water mist.

[0032] Furthermore, to improve the use effect, the nozzle 17 is connected to the inner air guiding shell 304 through an elastic pull rope 15. The elastic pull rope 15 passes through the rope winding seat 14, and the rope winding seat 14 is fixed on the conical shell 3. Spray holes 3041 are formed on the inner air guiding shell 304. When the sliding hydraulic rod 13 is in the maximum extended state, the nozzle 17 is aligned with the spray holes 3041, and the water mist ejected from the nozzle 17 passes through the spray holes 3041 and reaches the nozzle of the inner air guiding shell 304. When the sliding hydraulic rod 13 is in the maximum contracted state, the vast majority of the water mist ejected from the nozzle 17 is carried away by the diffused wind at the nozzle position of the second air guiding channel, thereby forming diffused water mist, which is convenient for workers to perform dust suppression during construction.

[0033] Meanwhile, when the sliding hydraulic rod 13 is in the maximum contracted state, the spraying directions of each nozzle 17 can still intersect on the spraying direction of the first air guiding channel. The vast majority of the water mist sprayed by the nozzle 17 will be carried away by the wind in the second air guiding channel at the nozzle position of the second air guiding channel. However, the larger water droplets that are not fully atomized or aggregated after atomization in the nozzle 17 will enter the nozzle position of the first air guiding channel due to their larger mass. The wind speed in the first air guiding channel is greater and more concentrated, and these larger water droplets will be carried by the wind in the first air guiding channel to a farther place. By only controlling the landing range of the dust suppression area within the second air guiding cylinder, workers can be prevented from getting their clothes wet by excessive water droplets during dust suppression.

[0034] In this embodiment, the blowing component includes a fan motor 11 and a fan 12. The fan motor 11 is fixed to the cylindrical shell 2, and a fan 12 is fixed on the motor shaft of the fan motor 11. The high-speed rotation of the fan 12 is controlled by the fan motor 11 to provide wind power for the spray dust suppression device.

[0035] In this embodiment, the adjustment assembly includes a pitching control assembly and a swinging control assembly. The pitching control assembly includes a pitching hydraulic rod 4. One end of the cylinder body of the pitching hydraulic rod 4 is hinged to the hinge seat 8 of the seat body, and the rod head of the telescopic rod of the pitching hydraulic rod 4 is hinged to the hinge seat 7 of the housing. The housing hinge seat 7 is fixed on the conical shell 3. Two coaxial fixed shafts are fixed on both sides of the cylindrical shell 2. Both sides of the cylindrical shell 2 are rotationally connected to the tops of two support columns 9 through the two fixed shafts. The bottom end of each support column 9 is fixed on the rotating base 5.

[0036] The swinging control assembly includes the rotating base 5, a rotation control motor 18 and a motor fixing bracket 10. The rotating base 5 is rotationally matched with the cylindrical shell 2. The motor fixing bracket 10 is fixed inside the cylindrical shell 2. The body of the rotation control motor 18 is fixed on the motor fixing bracket 10. The motor shaft of the rotation control motor 18 is fixed at the central position of the rotating base 5. When performing spray dust suppression, the rotation control motor 18 is controlled to rotate through the control board. The rotation control motor 18 drives the rotating base 5 to rotate, and the rotating base 5 then drives the entire spray dust suppression device to swing left and right. The pitching hydraulic rod 4 in the pitching control assembly controls the pitching swing of the spray dust suppression device around the top of the rotation control motor 18 by telescoping. The all-round coverage dust suppression of a certain space around the spray dust suppression device is realized through the pitching control assembly and the swinging control assembly.

It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
