Description

Technical Field

[0001] This invention relates to the field of environmentally friendly construction site water spraying and dust suppression technology, and particularly to environmentally friendly construction site water spraying and dust suppression devices. Background Technology

[0002] At construction sites, the lack of hardened ground causes dust to rise during construction work. This dust spreads everywhere, affecting workers and creating a poor working environment. It also impacts the health of those around the site. Currently, the most common method for dealing with construction dust is to spray water to reduce it.

[0003] Whether using mist cannons or atomized water pipes installed on isolation walls to spray water and suppress dust at unpaved construction sites, the water is sprayed directly into the air. This results in uneven water distribution in some areas and poor dust suppression. If the water flow directly impacts the unpaved ground, it will cause dust to fly up, increasing the spraying time and wasting water resources.

[0004] Therefore, it is necessary to invent an environmentally friendly dust suppression device for construction sites to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an environmentally friendly dust suppression device for construction sites, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly construction site water spraying and dust suppression device, comprising a placement frame, a roller rotatably inserted inside the placement frame, rotating shafts on both sides of the roller, the rotating shafts being rotatably inserted inside the placement frame, an installation frame inside the roller, several nozzles on both sides of the installation frame, a through hole in the roller at the nozzle position, an arc-shaped baffle on one side of the roller, the arc-shaped baffle being fixedly connected to the installation frame, water-blocking blocks at both ends of the arc-shaped baffle, and a water collection pipe at the bottom of the arc-shaped baffle;

[0007] A water spray plate is provided at the bottom of the water collection pipe, a water blocking device is provided between the arc-shaped baffle and the water collection pipe, and a drainage device is provided inside the water collection pipe.

[0008] The drainage device includes a sealing plate (23) and two auxiliary plates (24). The two ends of the auxiliary plates (24) are fixedly connected to the inner wall of the water collection pipe (15). An auxiliary rod (25) is movably inserted inside the auxiliary plate (24). The bottom of the auxiliary rod (25) is fixedly connected to the sealing plate (23). A push block (26) is fixedly connected to the top of the sealing plate (23). A second spring (27) is sleeved on the surface of the auxiliary rod (25) at the insertion point of the auxiliary plate (24).

[0009] The drainage device discharges the water collected in the water collection pipe (15) from the sprinkler plate (16), so that the water flow wets the dust on the ground. The drainage device only drains water when the water blocking device is working, providing time for the water to collect in the water collection pipe.

[0010] Furthermore, the water-blocking device includes a rotating groove and two working grooves. A rotating plate is rotatably inserted into one side of the rotating groove, and a fixed rod is rotatably inserted into the inside of one side of the rotating plate. Both ends of the fixed rod are fixedly connected to the inner wall of the rotating groove. A movable rod is movably inserted into the inside of the working groove. The top of the movable rod is fixedly connected to the bottom of the rotating plate, and a first spring is fixedly connected to the bottom of the movable rod. One end of the first spring is fixedly connected to the inner wall of the working groove.

[0011] Furthermore, the bottom of the placement rack is provided with several pulleys, the top of the placement rack is provided with a push rod, the inside of the placement rack is provided with a water tank, a reduction motor is provided on one side of the water tank, and a transmission belt is sleeved between the output end of the reduction motor and the rotating shaft.

[0012] Furthermore, the mounting bracket is provided with a conduit, one side of which is fixedly connected to the bottom of the nozzle, one end of which extends through the roller and the rotating shaft to the outside, and the end of the conduit is fixedly connected to the water tank, and a section in the middle of the conduit is rotatably sealed.

[0013] Furthermore, both the moving rod and the first spring are arc-shaped, and the inner wall of the working groove matches them. The two moving rods are located at both ends of the arc-shaped baffle.

[0014] Furthermore, the top of the sealing plate is sloped, and the inside of the water collection pipe matches it. A sealing strip is provided on the slope of the sealing plate.

[0015] Furthermore, the top of the push block is arc-shaped, and the auxiliary rod is located at both ends of the water collection pipe.

[0016] Furthermore, the top of the water-blocking block is arc-shaped, and the top of the water-blocking block is in contact with the surface of the roller.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. The present invention, by setting up a roller, helps to press the airborne dust into the ground from top to bottom by the water mist sprayed from the nozzle, making the water spraying area more even. After the nozzle enters the arc-shaped baffle, it avoids the water mist directly impacting the unhardened ground. The water flow into the arc-shaped baffle flows out from the water collection pipe to moisten the ground dust and prevent the ground dust from being raised and spread again.

[0019] 2. The present invention has a drainage device, which facilitates the discharge of water collected in the water collection pipe from the sprinkler plate, so that the water flow can moisten the dust on the ground. The drainage device only drains water when the water blocking device is working, which provides time for the water to collect in the water collection pipe, making the outflowing water flow more gentle and not impacting the dust on the ground.

[0020] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0029] This invention provides an environmentally friendly dust suppression device for construction sites, such as... Figure 1-5 As shown, the device includes a placement frame 1, inside which a roller 8 is rotatably inserted. Rotating shafts 9 are provided on both sides of the roller 8, and these shafts 9 are rotatably inserted into the placement frame 1. An mounting frame 10 is provided inside the roller 8, and several nozzles 11 are provided on both sides of the mounting frame 10. A through hole 12 is provided on the roller 8 at the nozzle 11 position. An arc-shaped baffle 13 is provided on one side of the roller 8, and the arc-shaped baffle 13 is fixedly connected to the mounting frame 10. Water-blocking blocks 14 are provided at both ends of the arc-shaped baffle 13, with the top of each water-blocking block 14 being arc-shaped and fitting against the surface of the roller 8. A water collection pipe 15 is provided at the bottom of the arc-shaped baffle 13.

[0030] A water spray plate 16 is provided at the bottom of the water collection pipe 15, a water blocking device is provided between the arc-shaped baffle 13 and the water collection pipe 15, and a drainage device is provided inside the water collection pipe 15.

[0031] When water spraying is needed to suppress dust at a construction site, the rotation of the roller 8 drives the internal mounting frame 10 to rotate, and the nozzles 11 on the mounting frame 10 rotate accordingly. Water mist sprayed from one nozzle 11 exits through the through-hole 12 and flows outwards. The rotation of the roller 8 causes the nozzles 11 to rotate downwards, spraying water mist onto the construction site from top to bottom to suppress dust. The water mist presses airborne dust down to the ground. After rotating to a certain position, the nozzles 11 enter the curved baffle 13 to prevent the water mist from directly impacting the unhardened ground and causing dust to rise and spread again. The other nozzle rotates out of the curved baffle 13... When the dust suppression spraying operation begins, the water mist sprayed by the nozzle 11 is blocked by the water-blocking block 14 after entering the arc-shaped baffle 13, preventing the water flow from splashing everywhere and avoiding water waste. The water flow inside the arc-shaped baffle 13 is blocked by the drainage device and accumulates inside the water collection pipe 15. After the nozzle 11 enters the arc-shaped baffle 13, the water flow sprayed by the nozzle 11 impacts the water-blocking device. The operation of the water-blocking device drives the drainage device to work. The water flow collected inside the water collection pipe 15 is evenly sprayed on the ground through the water spraying plate 16, which moistens the dust on the ground and prevents the dust from spreading and flying up again.

[0032] The present invention, by setting up the roller 8, helps to press the airborne dust into the ground from top to bottom by the water mist sprayed by the nozzle 11, so that the water spraying area is more even. After the nozzle 11 enters the arc-shaped baffle 13, it avoids the water mist directly impacting the unhardened ground. The water flow entering the arc-shaped baffle 13 flows out from the water collection pipe 15 to moisten the ground dust and prevent the ground dust from being raised and spread again.

[0033] like Figure 2-5 As shown, the water-blocking device includes a rotating groove 17 and two working grooves 18. A rotating plate 19 is rotatably inserted into one side of the rotating groove 17, and a fixed rod 20 is rotatably inserted into the inside of one side of the rotating plate 19. The two ends of the fixed rod 20 are fixedly connected to the inner wall of the rotating groove 17. A movable rod 21 is movably inserted into the inside of the working groove 18. The top of the movable rod 21 is fixedly connected to the bottom of the rotating plate 19, and a first spring 22 is fixedly connected to the bottom of the movable rod 21. One end of the first spring 22 is fixedly connected to the inner wall of the working groove 18. Both the movable rod 21 and the first spring 22 are arc-shaped, and the inner wall of the working groove 18 matches them. The two movable rods 21 are located at both ends of the arc-shaped baffle 13.

[0034] After the nozzle 11 enters the arc-shaped baffle 13, the water jet from the nozzle 11 impacts the rotating plate 19. The impact force of the water jet pushes the rotating plate 19, causing it to rotate around the fixed rod 20. The movement of the rotating plate 19 moves the moving rod 21, causing it to retract into the working groove 18. The first spring 22 contracts, and the water jet impacts the rotating plate 19, causing the water jet to split to both sides. The water jet on one side is blocked by the water-blocking block 14 and falls into the water collection pipe 15 from the rotating groove 17. The water jet on the other side flows along the arc-shaped baffle 13 and is affected by gravity. The force falls from the bottom of one side of the arc-shaped baffle 13 into the water collection pipe 15. The water flow will not directly impact the drainage device, and the drainage device can work normally. The water flow flows into the water collection pipe 15 more gently. After the nozzle 11 leaves the position of the rotating plate 19, the first spring 22 resets and pushes the moving rod 21 back to its original position. The rotating plate 19 then rotates back to its original position. The water flow sprayed from the nozzle 11 directly impacts the arc-shaped baffle 13. The diverted water flow impacts the bottom of the arc-shaped baffle 13 and then falls into the water collection pipe 15. The water flow will not directly rush into the water collection pipe 15.

[0035] By incorporating a water-blocking device, this invention helps reduce the impact force of water flowing into the water collection pipe 15, allowing the water to flow more gently into the water collection pipe 15. The water flow will not impact the drainage device, enabling the drainage device to properly drain the water collected in the water collection pipe 15.

[0036] like Figure 2-5As shown, the drainage device includes a sealing plate 23 and two auxiliary plates 24. The two ends of the auxiliary plates 24 are fixedly connected to the inner wall of the water collection pipe 15. An auxiliary rod 25 is movably inserted into the auxiliary plate 24. The bottom of the auxiliary rod 25 is fixedly connected to the sealing plate 23. A pushing block 26 is fixedly connected to the top of the sealing plate 23. A second spring 27 is sleeved on the surface of the auxiliary rod 25 at the insertion point of the auxiliary plate 24. The top of the sealing plate 23 is sloped, and the inside of the water collection pipe 15 matches it. A sealing strip is provided at the slope position of the sealing plate 23. The top of the pushing block 26 is arc-shaped. The auxiliary rod 25 is located at both ends of the water collection pipe 15.

[0037] After the nozzle 11 enters the arc-shaped baffle 13, the water jet from the nozzle 11 impacts the water-blocking device. Since the top of the push block 26 is arc-shaped, the movement of the rotating plate 19 pushes the push block 26. The movement of the push block 26 causes the auxiliary rod 25 to move, the second spring 27 is compressed, and the movement of the auxiliary rod 25 causes the sealing plate 23 to move. The seal between the sealing plate 23 and the water collection pipe 15 is canceled, and the water collected on the sealing plate 23 is discharged from the water collection pipe 15. After the rotating plate 19 moves up, the second spring 27 resets, causing the auxiliary rod 25 and the push block 26 to return to their original positions. The sealing plate 23 then returns to its original position, and the seal between the sealing plate 23 and the water collection pipe 15 is resealed. The water then collects again on the sealing plate 23.

[0038] The present invention has a drainage device, which facilitates the discharge of water collected in the water collection pipe 15 from the sprinkler plate 16, so that the water flow can moisten the dust on the ground. The drainage device only drains water when the water blocking device is working, which provides time for the water flow to collect in the water collection pipe 15, making the outflowing water flow more gentle and not impacting the dust on the ground.

[0039] like Figure 1-2 As shown, the bottom of the placement frame 1 is provided with several pulleys 2, the top of the placement frame 1 is provided with a push rod 3, the inside of the placement frame 1 is provided with a water tank 4, a reduction motor 6 is provided on one side of the water tank 4, a conveyor belt 7 is sleeved between the output end of the reduction motor 6 and the rotating shaft 9, the inside of the mounting frame 10 is provided with a guide tube 5, one side of the guide tube 5 is fixedly connected to the bottom of the nozzle 11, one end of the guide tube 5 passes through the roller 8 and the rotating shaft 9 and extends to the outside, and the end of the guide tube 5 is fixedly connected to the water tank 4, and a section in the middle of the guide tube 5 is rotatably sealed.

[0040] When it is necessary to spray water to reduce dust at the construction site, push the push rod 3 to move, and the mounting frame 1 moves under the action of the pulley 2. The reduction motor 6 drives the rotating shaft 9 to rotate through the transmission belt 7, and the roller 8 can then rotate. The water in the water tank 4 enters the nozzle 11 through the conduit 5, and the nozzle 11 can then spray water. When the roller 8 drives the mounting frame 10 to rotate, this section of the conduit 5 rotates accordingly. Since the middle section of the conduit 5 is sealed, the two sections of the conduit 5 will not affect each other and will transport water normally without affecting the spraying operation of the nozzle 11.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
