Description

Technical Field

[0001] The present invention belongs to the technical field of green construction, and specifically relates to an automatic water mist dust reduction device for green building construction. Background Art

[0002] During the construction process, dust is inevitable. Once the dust on the construction site spreads everywhere, it will have an impact on the environment, especially on the living environment of the residents near the construction site. Seriously, it will affect the physical and mental health of the residents. During the construction process, the construction unit will set up a circle of fences around the construction site to isolate the construction site. In order to prevent the dust generated at the construction site from spreading outside the fence, the construction unit often sets up a dust reduction device on the fence to control the dust. By spraying water through the dust reduction device, the dust is made to fall to the ground, avoiding the adverse impact on the surrounding environment caused by the spread of dust outside the construction site.

[0003] The current dust reduction device makes the dust fall to the ground and concentrate near the fence. After the dust dries, it is easily blown up by the wind (and can also be carried up by vehicles where there are vehicles passing by), causing secondary pollution; the dust reduction device generally works continuously for a long time, so more water resources are required. At present, the sprayed water of the dust reduction device directly falls to the ground and cannot be reused, resulting in a great waste of water resources. Summary of the Invention

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. In the present invention, the dust follows the water mist into the water receiving tank. After the dust follows the water mist into the water receiving tank, it precipitates at the bottom of the water receiving tank, achieving dust reduction. Moreover, the dust accumulates in the water receiving tank, preventing the dust from falling to the ground and being carried away by the wind to cause secondary pollution, thereby improving the dust reduction quality. After the water mist enters the water receiving tank, it condenses into water. When the water condenses to a certain height, it enters the water storage tank through the drain pipe, realizing the recycling of water and saving water. When strong winds blow, the lifting seat and the water receiving plate are located inside the water receiving tank, preventing the wind from damaging the lifting seat and the water receiving plate, reducing the probability of the dust reduction device being damaged by strong winds, and improving the reliability of the dust reduction device. When installing and removing the water receiving tank, the lifting seat, the water receiving plate, etc., the lifting mechanism is used to move the lifting seat and the water receiving plate into the water receiving tank, facilitating the installation and removal of the water receiving tank, the lifting seat, the water receiving plate, etc., improving the convenience of the dust reduction device, and at the same time reducing the probability of damaging the lifting seat, the water receiving plate, etc. during the installation and removal process, and reducing the probability of damage to the dust reduction device.

[0029] 2. When the lifting seat moves upward in the present invention, it drives the third connecting member upward. The third connecting structure drives the second limiting structure upward, driving the second connecting cylinder upward. The second connecting structure drives the first limiting structure upward, driving the first connecting cylinder upward, driving the connecting frame upward. When the lifting seat moves downward, it drives the third connecting member downward. The elastic telescopic mechanism makes the water receiving plate press against the slope structure, preventing the water receiving plate from rotating, keeping the connecting frame and the first connecting cylinder stationary. The lifting seat continues to move downward until the third connecting structure abuts against the connecting frame. The lower ends of the second connecting cylinder and the third connecting member both abut against the connecting frame, and the upper ends of the first connecting cylinder and the second connecting cylinder both abut against the lower surface of the lifting seat. The lifting seat continues to move downward, and the lower end of the third connecting member exerts a thrust on the connecting frame, causing the connecting frame to generate a downward force, making the connecting frame move downward synchronously with the lifting seat, overcoming the acting force of the elastic telescopic mechanism, shortening the elastic telescopic mechanism, making the two water receiving plates rotate around the rotating shaft, and making the water receiving plate move downward following the connecting frame, realizing the up and down movement of the connecting frame.

[0030] 3. After a certain thickness of dust precipitates in the water receiving tank in the present invention, the lifting mechanism drives the lifting seat to move downward. The fourth fixing plate exerts a thrust on the first rod-shaped structure, overcoming the elastic force of the first elastic member and the gravity of the first sliding block, making the first sliding block move towards the upper cover side. When the lifting seat and the upper end of the first connecting cylinder abut together, the first connecting groove communicates with the third tubular structure. When the connecting frame approaches the bottom of the water receiving tank, the water pump is operated to make water enter the fourth connecting groove and spray out through the fourth spray holes, flushing the precipitated dust, and making the precipitated dust and water drain out together through the sewage pipe.

[0031] 4. During dust reduction in the present invention, the first through hole and the drain hole are connected, enabling the water in the water receiving tank to enter the drain pipe through the drain hole and the first through hole, recycling the water. At the same time, the first sliding plate seals the sewage discharge hole to prevent water from flowing out through the sewage discharge hole, saving water. When cleaning the precipitated dust, the second through hole is aligned with the sewage discharge hole, allowing water and dust to enter the sewage pipe through the sewage discharge hole and the second through hole to clean the dust. At the same time, the first sliding plate seals the drain hole to prevent water and dust from entering the water storage tank, improving the cleanliness of the water in the water storage tank and reducing the probability of blockage of the spray structure and the fourth spray holes.

DETAILED DESCRIPTION

[0053] In order to make the technical means, creative features, achieved objectives and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0054] As Figures 1-19 shown, an automatic water mist dust reduction device for green building construction includes a water receiving tank 11, a lifting seat 12, a connecting frame 13, a water receiving plate 14, a water spraying pipe 15 and a water storage tank 16; slope structures 111 are symmetrically arranged on two opposite side walls of the water receiving tank 11; the slope structures 111 are arranged along the long side direction of the water receiving tank 11;

[0055] The lifting seat 12 is connected inside the water receiving tank 11; the lifting seat 12 is connected to the bottom plate of the water receiving tank 11 through a lifting mechanism 2; the lifting mechanism 2 is used to drive the lifting seat 12 to rise or fall; the connecting frame 13 is connected inside the water receiving tank 11; the connecting frame 13 is connected to the lifting seat 12 through a first connecting mechanism 3;

[0056] Water receiving plates 14 are symmetrically arranged on both sides of the connecting frame 13; rotating shafts 141 are evenly spaced and connected to the lower ends of the water receiving plates 14; the rotating shafts 141 are rotatably connected to the connecting frame 13; an elastic telescopic mechanism 4 is connected between the two water receiving plates 14; the elastic telescopic mechanism 4 is evenly spaced along the long side direction of the water receiving plate 14; both ends of the elastic telescopic mechanism 4 are rotatably connected to the two water receiving plates 14 respectively;

[0057] A first fixed pipe 51 and a second fixed pipe 52 are fixedly connected to the lifting seat 12; the second fixed pipe 52 is connected to the first fixed pipe 51 through a second communication mechanism 6; water spraying pipes 15 are symmetrically arranged at both ends of the second fixed pipe 52; the water spraying pipes 15 are fixedly connected to the lifting seat 12; the water spraying pipes 15 are communicated with the second fixed pipe 52; both ends of the water spraying pipes 15 are closed; spray structures 151 are arranged on the outer walls of the water spraying pipes 15; the spray structures 151 are used to form water mist and spray it downward;

[0058] The water storage tank 16 is fixed on the ground; a water pump 53 is fixedly connected to the water storage tank 16; a first connecting pipe 54 is fixedly connected to the water inlet end of the water pump 53; the lower end of the first connecting pipe 54 is arranged close to the bottom plate of the water storage tank 16; the water outlet end of the water pump 53 is communicated with the first fixed pipe 51 through a second connecting pipe 55; the water receiving tank 11 is communicated with the water storage tank 16 through a drain pipe 56.

[0059] During operation, the staff member operates the lifting mechanism 2 through the controller. The lifting mechanism 2 drives the lifting seat 12 to move upward until the lifting seat 12 reaches the highest position and remains stationary. During the upward movement of the lifting seat 12, the first connecting mechanism 3 drives the connecting frame 13 to move upward. The connecting frame 13 drives the rotating shaft 141 to move upward, which in turn drives the two water receiving plates 14 to move upward. Under the action of the elastic telescopic mechanism 4, the side walls of the two water receiving plates 14 abut against the lower edges of the two slope structures 111, and the water receiving plates 14 slide along the lower edges of the slope structures 111. At the same time, under the action of the elastic telescopic mechanism 4, the two water receiving plates 14 slowly rotate around the rotating shaft 141, causing the upper ends of the two connecting plates to gradually move away from each other. When the lifting seat 12 reaches the highest position, the connecting frame 13 also reaches the highest position, and the sides of the two water receiving plates 14 just abut against the slope structures 111, keeping the water receiving plates 14 in an inclined state, thus realizing the opening of the water receiving plates 14. Subsequently, the staff member operates the water pump 53 through the controller. The water pump 53 causes the water in the water storage tank 16 to pass through the first connecting pipe 54, the water pump 53, the second connecting pipe 55, the first fixed pipe 51, the second connecting mechanism 6, and the second fixed pipe 52 in sequence and enter the spray pipe 15, and is sprayed downward through the spray structure 151 to form and eject water mist downward. The water mist moves downward. A part of the water mist directly falls into the water receiving tank 11, and another part of the water mist falls onto the water receiving plates 14 and flows downward along the water receiving plates 14, finally entering the water receiving tank 11. When the water mist moves downward, it carries the dust in the air, causing the dust to enter the water receiving tank 11 together with the water mist. After the dust follows the water mist into the water receiving tank 11, it precipitates at the bottom of the water receiving tank 11, realizing dust reduction. Moreover, the dust accumulates in the water receiving tank 11, preventing the dust from falling to the ground and being carried up by the wind (or vehicles, etc.) to cause secondary pollution, thereby improving the dust reduction quality. After the water mist enters the water receiving tank 11, it condenses into water. When the water condenses to a certain height, it enters the water storage tank 16 through the drain pipe 56, realizing the recycling of water and saving water.

[0060] When strong winds blow, the staff operate the lifting mechanism 2 through the controller. The lifting mechanism 2 drives the lifting seat 12 to move downward. During the downward movement of the lifting seat 12, the connecting frame 13 is driven to move downward through the first connecting mechanism 3. The connecting frame 13 drives the water receiving plate 14 to move downward. The water receiving plate 14 slides along the lower edge of the slope structure 111. The lower edge of the slope structure 111 exerts a force on the side wall of the water receiving plate 14, causing the upper ends of the two water receiving plates 14 to approach each other, realizing the retraction of the water receiving plate 14. After the lifting seat 12 moves to the lowest position, the lifting mechanism 2 stops working. At this time, the lifting seat 12 moves into the water receiving tank 11, and at the same time, the connecting frame 13 moves to the lowest position, and the water receiving plate 14 moves into the water receiving tank 11, so that the lifting seat 12 and the water receiving plate 14 are located in the water receiving tank 11, preventing the wind from damaging the lifting seat 12 and the water receiving plate 14, reducing the probability of the dust suppression device being damaged by strong winds, and improving the reliability of the dust suppression device during operation;

[0061] When installing and removing the water receiving tank 11, the lifting seat 12, the water receiving plate 14, etc., the lifting seat 12 and the water receiving plate 14 are moved into the water receiving tank 11 through the lifting mechanism 2, which facilitates the installation and removal of the water receiving tank 11, the lifting seat 12, the water receiving plate 14, etc., and improves the convenience of the dust suppression device; when installing and removing the water receiving tank 11, the lifting seat 12, the water receiving plate 14, etc., the lifting seat 12 and the water receiving plate 14 are moved into the water receiving tank 11 through the lifting mechanism 2, reducing the probability of damage to the lifting seat 12, the water receiving plate, etc. during the installation and removal process, and reducing the probability of damage to the dust suppression device.

[0062] The first connecting mechanism 3 includes a first connecting cylinder 31, a second connecting cylinder 32 and a third connecting member 33; the first connecting cylinders 31 are evenly spaced on the connecting frame 13; the lower end of the first connecting cylinder 31 is fixedly connected to the connecting frame 13; the upper end of the first connecting cylinder 31 is provided with a first limiting structure 311; the second connecting cylinder 32 is slidably connected in the first connecting cylinder 31; the lower end of the second connecting cylinder 32 is provided with a second connecting structure 321; the upper end of the second connecting cylinder 32 is provided with a second limiting structure 322; the third connecting member 33 is slidably connected in the second connecting cylinder 32; the lower end of the third connecting member 33 is provided with a third connecting structure 331; the upper end of the third connecting member 33 is fixedly connected to the lifting seat 12; the limiting parts 112 are symmetrically arranged on the opposite side walls of the water receiving tank 11.

[0063] When the lifting seat 12 moves upward, it drives the third connecting member 33 to move upward. When the third connecting structure 331 abuts against the second limiting structure 322, the third connecting structure 331 drives the second limiting structure 322 to move upward, driving the second connecting cylinder 32 to move upward. When the second connecting structure 321 abuts against the first limiting structure 311, the second connecting structure 321 drives the first limiting structure 311 to move upward, driving the first connecting cylinder 31 to move upward, driving the connecting frame 13 to move upward. When the lifting seat 12 moves downward, it drives the third connecting member 33 to move downward, driving the third connecting structure 331 to move downward. The second connecting cylinder 32 moves downward under the action of its own gravity and the friction force of the third connecting member 33. At this time, the elastic telescopic mechanism 4 causes the water receiving plate 14 to be pressed against the slope structure 111, preventing the water receiving plate 14 from rotating, and keeping the connecting frame 13 and the first connecting cylinder 31 stationary. The lifting seat 12 continues to move downward until the third connecting structure 331 abuts against the connecting frame 13. At this time, the second connecting structure 321 abuts against the connecting frame 13. The lower ends of the second connecting cylinder 32 and the third connecting member 33 both abut against the connecting frame 13, and the upper ends of the first connecting cylinder 31 and the second connecting cylinder 32 both abut against the lower surface of the lifting seat 12. The lifting seat 12 continues to move downward, and the lower end of the third connecting member 33 generates a thrust on the connecting frame 13, causing the connecting frame 13 to generate a downward acting force, causing the connecting frame 13 to move downward synchronously with the lifting seat 12, overcoming the acting force of the elastic telescopic mechanism 4, shortening the elastic telescopic mechanism 4, causing the two water receiving plates 14 to rotate around the rotating shaft 141, and causing the water receiving plate 14 to move downward following the connecting frame 13, realizing the up and down movement of the connecting frame 13; when the lifting seat 12 moves to the highest position and stops moving, the connecting frame 13 moves to the highest position, and the connecting frame 13 abuts against the lower end surface of the limiting portion 112.

[0069] A fourth fixing plate 66 is arranged between two of the first connection cylinders 31; both ends of the fourth fixing plate 66 are fixedly connected to the two first connection cylinders 31 respectively; a sewage discharge pipe 67 is connected to the water receiving tank 11.

[0070] After the dust in the water receiving tank 11 has settled to a certain thickness, the staff discharges the water at the bottom of the water receiving tank 11 through the sewage discharge pipe 67. The lifting mechanism 2 is operated through the controller, and the lifting mechanism 2 drives the lifting seat 12 to move downward. When the lifting seat 12 is about to contact the upper end of the first connecting cylinder 31, the first rod-shaped structure 622 contacts the fourth fixing plate 66. As the lifting seat 12 continues to move downward, the fourth fixing plate 66 exerts a thrust on the first rod-shaped structure 622, overcoming the elastic force of the first elastic member 63 and the gravity of the first sliding block 62, causing the first sliding block 62 to move toward the upper cover 61 side, and causing the first connecting groove 621 to move toward the upper cover 61 side. When the lifting seat 12 contacts the upper end of the first connecting cylinder 31, the lower end surface of the first rod-shaped structure 622 is flush with the lower end surface of the lifting seat 12. At this time, the first connecting groove 621 is aligned with the third tubular structure 1212, and the first connecting groove 621 communicates with the third tubular structure 1212. When the connecting frame 13 approaches the bottom of the water receiving tank 11, the water pump 53 is operated through the controller, so that the water in the water storage tank 16 passes through the first connecting pipe 54, the water pump 53, the second connecting pipe 55, the first fixing pipe 51, the first tubular structure 611, the first cylindrical structure 623, the first connecting groove 621, the third tubular structure 1212, the fourth fixing pipe 64, the fourth connecting pipe 65, and the fourth square tube structure 131 and enters the fourth connecting groove 132, and is sprayed out through the fourth spray holes 133 to wash the settled dust, so that the settled dust and water are discharged together through the sewage discharge pipe 67 to clean the settled dust, prevent excessive accumulation of dust from entering the water storage tank 16 along with the water, and reduce the probability of blockage of the spraying structure 151;

[0071] After the cleaning of the settled dust is completed, the lifting mechanism 2 is operated through the controller to move the lifting seat 12 to the highest position. At this time, the first rod-shaped structure 622 has long since separated from the fourth fixing plate 66. Under the action of the elastic force of the first elastic member 63 and the gravity of the first sliding block 62, the first sliding block 62 moves away from the upper cover 61 side and contacts the bottom surface of the box structure 121. At this time, the first connecting groove 621 communicates with the second tubular structure 1211. When the water pump 53 is operating, the water in the water storage tank 16 passes through the first connecting pipe 54, the water pump 53, the second connecting pipe 55, the first fixing pipe 51, the first tubular structure 611, the first cylindrical structure 623, the first connecting groove 621, the second tubular structure 1211, the second fixing pipe 52, and enters the water spray pipe 15, and is sprayed downward through the spraying structure 151 for dust reduction.

[0072] A first sliding plate 17 is slidably connected to the side wall of the water receiving tank 11; the first sliding plate 17 is provided with a first through hole 171 and a second through hole 172; the first through hole 171 is arranged above the second through hole 172;

[0073] The upper end of the drain pipe 56 is fixedly connected to the first sliding plate 17; the upper end of the sewage pipe 67 is fixedly connected to the first sliding plate 17; the drain pipe 56 communicates with the first through hole 171; the sewage pipe 67 communicates with the second through hole 172; the side wall of the water receiving tank 11 is provided with a drain hole 113 and a sewage discharge hole 114; the sewage discharge hole 114 is arranged close to the bottom plate of the water receiving tank 11.

[0074] During dust reduction, the first sliding plate 17 is located at the highest position, the first through hole 171 is aligned with the drain hole 113, and the first through hole 171 and the drain hole 113 are communicated, so that the water in the water receiving tank 11 enters the drain pipe 56 through the drain hole 113 and the first through hole 171 for recycling of water. At the same time, the first sliding plate 17 blocks the sewage discharge hole 114 to prevent water from flowing out through the sewage discharge hole 114, saving water. When cleaning the precipitated dust, the first sliding plate 17 is pulled downward so that the first sliding plate 17 is located at the lowest position. At this time, the second through hole 172 is aligned with the sewage discharge hole 114, so that water and dust enter the sewage pipe 67 through the sewage discharge hole 114 and the second through hole 172 to clean the dust. At the same time, the first sliding plate 17 blocks the drain hole 113 to prevent water and dust from entering the water storage tank 16 through the drain hole 113, the first through hole 171, and the drain pipe 56, improving the cleanliness of the water in the water storage tank 16 and reducing the probability of blockage of the spray structure 151 and the fourth spray hole 133.

[0075] Lifting mechanisms 2 are symmetrically arranged in the water receiving tank 11; the lifting mechanism 2 includes a third connecting plate 21, a third sliding block 22, a fourth connecting plate 23, a fourth sliding block 24, a scissor mechanism 25, a fourth connecting shaft 26, and a fourth motor 27.

[0076] The third connecting plate 21 is fixedly connected to the bottom plate of the water receiving tank 11; one end of the third connecting plate 21 is slidably connected to the third sliding block 22; the other end of the third connecting plate 21 is provided with a third hinge portion 211; the lower surface of the lifting seat 12 is fixedly connected to the fourth connecting plate 23; one end of the fourth connecting plate 23 is slidably connected to the fourth sliding block 24; the other end of the fourth connecting plate 23 is provided with a fourth hinge portion 231.

[0077] The fourth connecting plate 23 and the third connecting plate 21 are connected by a scissor mechanism 25; the scissor mechanism 25 is symmetrically arranged on both sides of the third sliding block 22; one strut at the lower end of the scissor mechanism 25 is rotatably connected to the third sliding block 22; the other strut at the lower end of the scissor mechanism 25 is rotatably connected to the third hinge portion 211; one strut at the upper end of the scissor mechanism 25 is rotatably connected to the fourth sliding block 24; the other strut at the upper end of the scissor mechanism 25 is rotatably connected to the fourth hinge portion 231.

[0078] A fourth connecting plate 23 is rotatably connected to a fourth connecting shaft 26; a fourth sliding block 24 is threadedly connected to the fourth connecting shaft 26; a fourth motor 27 is fixedly connected to the lifting seat 12; the fourth connecting shaft 26 rotates synchronously with the rotating shaft of the fourth motor 27.

[0079] By means of the controller, the two fourth motors 27 work simultaneously. The rotating shafts of the two fourth motors 27 drive the two fourth connecting shafts 26 to rotate simultaneously, driving the fourth sliding blocks 24 to slide, causing the struts of the scissor mechanism 25 to swing, causing the scissor mechanism 25 to extend or contract, driving the two fourth connecting plates 23 to rise or fall, and driving the lifting seat 12 to rise or fall.

[0080] The elastic telescopic mechanism 4 includes a fifth connecting member 41, a sixth connecting member 42, and a sixth elastic member 43; one end of the fifth connecting member 41 is provided with a fifth rotating portion 411; the other end of the fifth connecting member 41 is provided with a fifth sliding groove 412; one end of the sixth connecting member 42 is provided with a sixth rotating portion 421; the other end of the sixth connecting member 42 is provided with a sixth connecting groove 422;

[0083] The elastic force of the sixth elastic member 43 generates a force that causes the sixth connecting member 42 and the fifth connecting member 41 to move away from each other, causing the side wall of the water receiving plate 14 to abut against the lower edge of the slope structure 111. When the connecting frame 13 drives the water receiving plate 14 to move upward, the elastic force of the sixth elastic member 43 causes the two water receiving plates 14 to slowly rotate around the rotating shaft 141, causing the upper ends of the two connecting plates to gradually move away from each other. When the connecting frame 13 abuts against the lower end surface of the limiting portion 112 and stops moving, the sides of the two water receiving plates 14 just abut against the slope structure 111, causing the water receiving plate 14 to maintain an inclined state, realizing the opening of the water receiving plate 14. When the connecting frame 13 drives the water receiving plate 14 to move downward, the water receiving plate 14 slides along the lower edge of the slope structure 111, and the lower edge of the slope structure 111 generates a force on the side wall of the water receiving plate 14, overcoming the elastic force of the sixth elastic member 43, causing the upper ends of the two water receiving plates 14 to approach each other, realizing the retraction of the water receiving plate 14. The water receiving plate 14 is opened during the upward movement of the connecting frame 13, and the water receiving plate 14 is retracted during the downward movement of the connecting frame 13.

[0085] The telescopic protective cover 7 prevents dust from adhering to the third sliding block 22, reducing the probability of the third sliding block 22 being stuck. The seal 7 prevents dust from adhering to the scissor mechanism 25, reducing the probability of the struts of the scissor mechanism 25 being stuck, and improving the reliability of the dust reduction device.
