Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology and relates to a building construction ventilation and air purification device. Background Technology
[0002] During construction, a large amount of dust is easily generated. Once the dust is raised, it will remain indoors for a long time, making it easy for workers to inhale a lot of dust, which can harm their health.
[0003] Currently, ventilation systems used in construction sites are not very effective at removing dust. Some methods use water spraying for dust removal, but ventilation and dust removal are separate systems, which result in large space requirements, low efficiency, and are not conducive to cost and energy savings.
[0004] To address the above problems, this invention proposes a building construction ventilation and air purification device. Summary of the Invention
[0005] To address the problems existing in the background technology, the present invention proposes a building construction ventilation and air purification device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building construction ventilation and air purification device, comprising a base, a wind-gathering duct, fan blades, and a spray plate mounted on the base; a mounting frame is fixedly installed inside the wind-gathering duct, and piston cylinders are provided at both ends of the mounting frame; a piston plate is elastically and slidably installed inside the piston cylinder, and a piston rod is fixedly connected to the piston plate; both ends of the piston rod pass through the piston cylinder; one end of the spray plate is slidably connected to one of the piston rods, and the other end of the spray plate is hinged to the other piston rod; the piston cylinder is connected to a water source; the spray plate is connected to the piston cylinder; a rotating shaft is rotatably installed inside the wind-gathering duct, and the fan blades are mounted on the rotating shaft; a first push rod and a second push rod are alternately fixedly installed on the rotating shaft; the first push rod pushes the piston rod away from the axis of the wind-gathering duct to move, and the second push rod pushes the piston rod close to the axis of the wind-gathering duct to move.
[0007] Furthermore, each of the two piston rods is fixed with a hinge seat; one end of the spray plate is fixedly connected to a second lug, and the other end is fixedly connected to a sliding seat; one of the hinge seats is connected to a sliding column, which is slidably disposed within the sliding seat, and the other hinge seat is hinged to the second lug.
[0008] Furthermore, the spray plate is provided with a water spray channel and multiple spray holes, and the spray holes are connected to the water spray channel; the water spray channel is connected to the piston cylinder.
[0009] Furthermore, a water outlet channel is provided on the piston rod, one end of which is connected to the piston cylinder, and the other end of which is connected to the water spray channel through a hose. A first one-way valve is provided inside the water outlet channel.
[0010] Furthermore, a fixing plate is fixedly installed inside the air-gathering duct, and multiple mounting brackets are spaced apart on the outer circumference of the fixing plate, with each mounting bracket corresponding to a spray plate.
[0011] Furthermore, the mounting bracket is provided with a water inlet channel, the piston cylinder is connected to the water inlet channel through a water inlet pipe, and a second one-way valve is provided on the water inlet pipe; the fixing plate is provided with a water distribution channel connected to the water source, and the water distribution channel is connected to the water inlet channel through a water distribution pipe.
[0012] Furthermore, the first push rod is Z-shaped.

[0014] Furthermore, the air-collecting duct is fixed with a fixing screw, which is rotatably connected to the support frame. The fixing screw is equipped with a clamping nut, which is used to fix the fixing screw to the support frame.
[0015] Furthermore, the lower end of the base is equipped with rollers.
[0016] Compared with existing technologies, the present invention has the following beneficial effects: While the fan blades rotate for ventilation, the first and second push rods rotate accordingly, causing the inner and outer piston rods to move alternately towards the spray plate. The piston plate reciprocates within the piston cylinder, drawing water from the water source into the piston cylinder and spraying it out through the spray plate to purify the air. Simultaneously, the alternating action of the inner and outer piston rods on the spray plate tilts the spray plate, changing its spray direction and expanding the spray area, thus improving air purification efficiency.

Detailed Implementation
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] like Figures 1-14As shown, the technical solution adopted by the present invention is as follows: a building construction ventilation and air purification device includes a base 1, a wind-gathering duct 11, a fan blade 14 and a spray plate 26 installed on the base 1.
[0034] A roller 2 is installed at the bottom of the base 1. An installation groove is provided on the base 1, within which two sliders 5 are slidably positioned. A lead screw 4 is rotatably mounted within the installation groove, and a first motor 3 is fixedly mounted on the base 1 to drive the lead screw 4. The threads on both sides of the lead screw 4 have opposite helical directions. The two sliders 5 are threadedly connected to both sides of the lead screw 4. Each slider 5 is hinged to a connecting rod 6, and each connecting rod 6 is hinged to a first lug 7. A support frame 8 is fixedly connected between the two first lugs 7. By rotating the lead screw 4, the two sliders 5 are moved closer or further apart, thereby adjusting the height of the support frame 8.
[0035] The air-concentrating duct 11 is rotatably mounted on the support frame 8. A fixing screw 9 is fixedly connected to the air-concentrating duct 11, and the fixing screw 9 is rotatably connected to the support frame 8. A clamping nut 10 is fitted to the fixing screw 9, which secures the fixing screw 9 to the support frame 8. The tilt angle of the air-concentrating duct 11 can be adjusted using the fixing screw 9.
[0036] A first fixed frame 12 and a second fixed frame 15 are fixedly installed inside the air-concentrating duct 11. A second motor 13 is fixedly installed on the first fixed frame 12, and a rotating shaft is coaxially fixed to the second motor 13. The end of the rotating shaft away from the second motor 13 is rotatably connected to the second fixed frame 15. The rotating shaft is coaxially arranged with the air-concentrating duct 11. The fan blades 14 are fixedly installed on the rotating shaft.
[0037] A fixing plate 16 is fixedly connected to the side of the second fixing frame 15 opposite to the first fixing frame 12. The fixing plate 16 is coaxially arranged with the air concentrator 11. Multiple mounting brackets 19 are fixedly fixed at intervals on the outer circumference of the fixing plate 16. A piston cylinder 20 is fixedly mounted at both ends of each mounting bracket 19, and the axis of the piston cylinder 20 is parallel to the axis of the air concentrator 11. The piston cylinder 20 is located on the side of the mounting bracket 19 opposite to the second fixing frame 15. Figure 9 As shown, a piston plate 23 is slidably disposed inside the piston cylinder 20. A spring 24 is fixedly connected between the piston plate 23 and the mounting bracket 19. A piston rod is fixedly connected to the piston plate 23, with both ends of the piston rod passing through the piston cylinder 20 and extending outside the piston cylinder 20. The end of the piston rod near the mounting bracket 19 passes through the mounting bracket 19 and extends outside the mounting bracket 19.
[0038] For ease of description, the piston rod closer to the axis of the air-collecting tube 11 is named the inner piston rod 21, and the piston rod farther from the axis of the air-collecting tube 11 is named the outer piston rod 22.
[0039] A spray plate 26 connects the inner piston rod 21 and the outer piston rod 22 on the same mounting bracket 19. Specifically, a hinge seat 25 is fixedly connected to one end of both the inner piston rod 21 and the outer piston rod 22 near the spray plate 26. A sliding seat 27 is fixedly connected to one end of the spray plate 26, and a second lug 28 is fixedly connected to the other end. A sliding post is connected to the hinge seat 25 on the outer piston rod 22, and the sliding post is slidably disposed within the sliding seat 27. The hinge seat 25 on the inner piston rod 21 is hinged to the second lug 28.
[0040] A first push rod 17 and a second push rod 18 are fixedly mounted on the rotating shaft, and the first push rod 17 and the second push rod 18 are arranged alternately. The first push rod 17 cooperates with the inner piston rod 21, and the second push rod 18 cooperates with the outer piston rod 22. The side of the first push rod 17 near the rotating shaft is bent away from the inner piston rod 21, thereby preventing the first push rod 17 from contacting the inner piston rod 21. Specifically, as shown... Figure 4 As shown, the first push rod 17 can be Z-shaped. The length of the second push rod 18 should be set appropriately to avoid contact between the second push rod 18 and the outer piston rod 22.
[0041] Both the inner piston rod 21 and the outer piston rod 22 have an arc-shaped end away from the spray plate 26. The cross-sections of the first push rod 17 and the second push rod 18 are both circular. This allows the first push rod 17 to smoothly push the outer piston rod 22 when it comes into contact with it, and the second push rod 18 to smoothly push the inner piston rod 21 when it comes into contact with it.
[0042] The spray plate 26 has a water spray channel 29 and multiple spray holes 30 communicating with the water spray channel 29. Both the inner piston rod 21 and the outer piston rod 22 have water outlet channels 32. One end of the water outlet channel 32 is connected to the piston cylinder 20, and the other end is connected to the water spray channel 29 via a hose 31. A first one-way valve 33 is installed on the water outlet channel 32, allowing water from the piston cylinder 20 to flow into the water spray channel 29 through the water outlet channel 32, the first one-way valve 33, and the hose 31.
[0043] The mounting bracket 19 has a water inlet channel 35, and both piston cylinders 20 are connected to the water inlet channel 35 via water inlet pipes 34. A second check valve is installed on the water inlet pipe 34 to open towards the piston cylinder 20. A water distribution pipe 36 is connected to the mounting bracket 19, with one end of the water distribution pipe 36 connected to the water inlet channel 35. A water distribution channel 37 is provided on the fixing plate 16, with the other end of the water distribution pipe 36 connected to the water distribution channel 37. The water distribution channel 37 is connected to a water supply pipe 38, which is connected to an external water source.
[0044] Working principle:
[0045] Push the device to the location requiring ventilation and adjust the height of the air-concentrating duct 11. Specifically, start the first motor 3, rotate the lead screw 4, causing the two sliders 5 to move closer together, thereby raising the support frame 8 and the air-concentrating duct 11. Then move the two sliders 5 away from each other, thereby lowering the air-concentrating duct 11.
[0046] Loosen the clamping nut 10 to rotate it around the fixing screw 9, and adjust the tilt angle of the air-concentrating duct 11. After adjusting the tilt angle of the air-concentrating duct 11, tighten the clamping nut 10 to fix the air-concentrating duct 11.
[0047] Then, the second motor 13 is started, the shaft rotates, and the fan blades 14 rotate to provide ventilation. The first push rod 17 and the second push rod 18 rotate simultaneously. As the first push rod 17 rotates, when it contacts the outer piston rod 22, it pushes the outer piston rod 22, causing it to move closer to the spray plate 26. The piston plate 23 connected to the outer piston rod 22 overcomes the elastic force of the spring 24 and moves closer to the spray plate 26, allowing water in the corresponding piston cylinder 20 to enter the water spray channel 29 through the water outlet channel 32, the first one-way valve 33, and the hose 31, and then spray out through the spray holes 30 to purify the air. At the same time, the end of the spray plate 26 away from the axis of the air collector 11 tilts away from the mounting bracket 19, thereby changing the water spray direction of the spray plate 26 and expanding the spray area.
[0048] After the first push rod 17 disengages from the outer piston rod 22, under the action of the spring 24, the outer piston rod 22 and piston plate 23 move away from the spray plate 26, and the piston cylinder 20 draws in water. Water from the water source enters the inlet pipe 34 through the water distribution channel 37, water distribution pipe 36, and water inlet channel 35, and flows into the corresponding piston cylinder 20. At the same time, the spray plate 26 resets.
[0049] When the second push rod 18 contacts the inner piston rod 21, the second push rod 18 pushes the inner piston rod 21, causing the inner piston rod 21 to move closer to the spray plate 26. The piston plate 23 connected to the inner piston rod 21 moves closer to the spray plate 26, and the water in the corresponding piston cylinder 20 flows into the water spray channel 29 and is sprayed out through the spray hole 30. At the same time, the inner piston rod 21 pushes the spray plate 26, causing the end of the spray plate 26 near the axis of the air collector 11 to tilt away from the mounting bracket 19, thereby changing the water spray direction of the spray plate 26.
[0050] When the second push rod 18 disengages from the inner piston rod 21, under the action of the spring 24, the inner piston rod 21 and the piston plate 23 move away from the spray plate 26, the piston cylinder 20 sucks water, and the spray plate 26 resets.
[0051] The first push rod 17 and the second push rod 18 are staggered, so that the first push rod 17 and the second push rod 18 act alternately on the piston rod, and the inner piston rod 21 and the outer piston rod 22 act alternately on the spray plate 26. This causes the spray plate 26 to change the spray direction during water spraying, expanding the spray area and improving air purification efficiency. Furthermore, the synergistic effect of ventilation and dust removal increases the coverage area of the water mist, making the water distribution more uniform and improving dust removal efficiency, further enhancing the air purification effect.
[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
