Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and specifically relates to a dust reduction device for green building construction and its operation method. Background Art

[0002] Green building construction refers to the construction activities in engineering construction that, on the premise of ensuring basic requirements such as quality and safety, through scientific management and technological progress, minimize resource consumption and reduce the negative impact on the environment. As an important stage in the whole life cycle of a building, green construction is the key link to achieve resource conservation and energy conservation and emission reduction in the building field. It requires implementing enclosed construction, reducing dust and noise, protecting the ecology and environment, and rationally using resources during the project construction. And reducing the generation of dust during the construction process requires the use of professional dust reduction equipment.

[0003] In the prior art, during the period when the dust reduction equipment for building construction stops operating, external dust and impurities easily enter the nozzle and cause blockage, making the nozzle unable to perform effective water spraying and dust reduction operations in the next time. Since there are many impurities in the water source for dust reduction, after long-term dust reduction operations, a layer of scale is likely to form on the inner wall of the nozzle. If not cleaned in time, the scale will block the nozzle and affect the subsequent water spraying and dust reduction operations.

[0004] Therefore, the present invention provides a dust reduction device for green building construction and its operation method. Summary of the Invention

[0009] Preferably, mounting blocks are fixedly connected inside the trapezoidal protrusions on the liquid inlet pipe. A first cavity is formed on one side of the mounting block close to the water spraying plate, and a second cavity is formed on one side of the mounting block close to the liquid storage hopper.

[0015] An operation method of a dust reduction device for green building construction includes the following steps:

[0016] S1: The staff externally connects the water inlet end of the water pump to a water supply device, starts the water pump, sends water into the water spraying pipe through the water supply pipe, and the water enters the water spraying plate through the first connecting pipe. Since the dust-proof plug blocks the nozzle, the water pressure in the second water storage cavity increases until the dust-proof plug disengages from the nozzle, and the water starts to spray out from the nozzle, realizing spray dust reduction for the building construction site.

[0017] S2: When cleaning the inner wall of the nozzle, fill the liquid storage hopper with cleaning liquid, stop the operation of the water pump, and the first sealing plate and the second sealing plate drive the dust-proof plug to reset. During this process, the cleaning liquid in the liquid storage hopper enters the second water storage cavity along the liquid inlet pipe and the second connecting pipe, realizing the wetting and softening of the scale on the inner wall of the nozzle. Then start the water pump again. The first sealing plate drives the dust-proof plug to separate from the nozzle again.

[0019] The beneficial effects of the present invention are as follows:

[0020] Through the cooperation of the first spring with the first sealing plate, the second sealing plate and the dust-proof plug and other structures, when the water pump stops operating, the nozzle is blocked, avoiding the entry of external dust and impurities into the nozzle during the stop of spraying by the spraying plate, resulting in nozzle blockage and affecting the next water spraying and dust reduction operation. And when the water pump starts operating, the cleaning ring scrapes the scale on the inner wall of the nozzle, avoiding the scale on the inner wall after long-term use of the nozzle.

Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] As Figures 1-9As shown in the figure, a dust reduction device for green building construction according to an embodiment of the present invention includes a mounting frame 1. A water pump 2 is fixedly installed at the lower part of the mounting frame 1. The water inlet end of the water pump 2 is externally connected to a water supply device. The water outlet end of the water pump 2 is fixedly connected to a water delivery pipe 3. The top end of the water delivery pipe 3 is provided with a water spraying pipe 4. The top end of the water spraying pipe 4 extends to the outside of the top layer of the mounting frame 1 and is fixedly connected to a water spraying plate 5. A fixing plate 8 is fixedly connected to one side of the inner cavity of the water spraying plate 5 close to the water spraying pipe 4. A first water storage cavity is formed between the fixing plate 8 and the inner cavity of the water spraying plate 5. On the side of the fixing plate 8 away from the water spraying pipe 4, there is a first sealing plate 9. On the side of the first sealing plate 9 away from the fixing plate 8, there is a second sealing plate 10. Both the first sealing plate 9 and the second sealing plate 10 are slidably connected to the inner cavity of the water spraying plate 5. Annular plates 13 are uniformly fixedly connected between the first sealing plate 9 and the second sealing plate 10. A second water storage cavity is formed between the second sealing plate 10 and the inner cavity of the water spraying plate 5. The water spraying pipe 4 is communicated with the first water storage cavity through a first connecting pipe 6. A water inlet pipe 11 is fixedly connected to the fixing plate 8. The first water storage cavity is communicated with the second water storage cavity through the water inlet pipe 11. The water inlet pipe 11 is slidably connected to both the first sealing plate 9 and the second sealing plate 10. A dust prevention component is arranged between the first sealing plate 9 and the second sealing plate 10. Nozzles 7 are uniformly installed on the outer wall of the water spraying plate 5 away from the water spraying pipe 4. The dust prevention component is adapted to the nozzles 7. Springs 12 are uniformly fixedly connected between the first sealing plate 9 and the fixing plate 8. During operation, the staff externally connects the water inlet end of the water pump 2 to a water supply device, and sends water into the water spraying pipe 4 through the cooperation of the water pump 2 and the water delivery pipe 3. The water in the water spraying pipe 4 enters the first water storage cavity formed by the fixing plate 8 and the water spraying plate 5 through the first connecting pipe 6, and then enters the second water storage cavity formed by the second sealing plate 10 and the water spraying plate 5 through the water inlet pipe 11. Since the dust prevention component blocks the nozzles 7, the water entering the second water storage cavity cannot be sprayed out from the nozzles 7. The water pressure in the second water storage cavity continuously increases until it drives the first sealing plate 9 and the second sealing plate 10 to slide and compress the springs 12. At the same time, the dust prevention component slides away from the nozzles 7 and cleans the scale on the inner walls of the nozzles 7, and the water starts to be sprayed out from the nozzles 7 to spray and reduce dust in the building construction site. When the dust reduction work is completed, the water pump 2 stops operating, the water pressure in the second water storage cavity starts to drop, the first sealing plate 9 and the second sealing plate 10 reset under the elastic force of the springs 12, and drive the dust prevention component to block the nozzles 7 again to prevent dust and impurities from entering the nozzles 7 and blocking the nozzles 7.

[0034] The dust-proof component includes a T-shaped rod 16 and a dust-proof plug 17. The T-shaped rods 16 are evenly arranged on the second sealing plate 10. One end of the T-shaped rod 16 extends into the nozzle 7 and is fixedly connected to the dust-proof plug 17. The end of the nozzle 7 is provided with a chamfer. The end of the dust-proof plug 17 is in close contact with the inner wall at the chamfer of the nozzle 7. There is a gap between the outer wall of the dust-proof plug 17 and the inner wall of the nozzle 7. A cleaning ring 20 is fixedly connected to the dust-proof plug 17. During operation, when the dust-proof plug 17 starts to move away from the nozzle 7, the cleaning ring 20 axially scrapes the scale on the inner wall of the nozzle 7. When the dust-proof plug 17 enters the nozzle 7 again, the chamfer design at the end of the nozzle 7 facilitates the quick sealing between the dust-proof plug 17 and the nozzle 7.

[0035] A liquid inlet pipe 24 is fixedly connected to the outer wall of one side of the water spraying plate 5 close to the water spraying pipe 4. A support 22 is fixedly connected to the outer wall of the top of the water spraying pipe 4. A liquid storage hopper 23 is fixedly connected to the top of the support 22. The bottom end of the liquid storage hopper 23 is communicated with the liquid inlet pipe 24. Two groups of symmetrical trapezoidal protrusions are provided on the liquid inlet pipe 24. Two sealing blocks 26 are slidably connected in the liquid inlet pipe 24. A connecting rod 25 is fixedly connected between the two sealing blocks 26. One end of the connecting rod 25 extends into the inner cavity of the water spraying plate 5 and is fixedly connected to the first sealing plate 9. The connecting rod 25 is slidably connected to the fixing plate 8. A plurality of second connecting pipes 27 are fixedly connected to one side of the liquid inlet pipe 24 close to the water spraying plate 5. The end of the second connecting pipe 27 away from the liquid inlet pipe 24 is communicated with the second water storage cavity. The second connecting pipe 27 is fixedly connected to the fixing plate 8. The second connecting pipe 27 is slidably connected to both the first sealing plate 9 and the second sealing plate 10. When the water pump 2 is not operating during work, the liquid inlet pipe 24 is in a state blocked by the sealing blocks 26. When the water pump 2 starts to operate and the water pressure in the second water storage cavity increases, the first sealing plate 9 drives the connecting rod 25 to slide, so that the two sealing blocks 26 slide towards the liquid storage hopper 23 side until the dust-proof plug 17 moves away from the nozzle 7, that is, when the first sealing plate 9 stops sliding, the two sealing blocks 26 block the liquid inlet pipe 24 again. When the water pump 2 stops operating again, the first sealing plate 9 drives the connecting rod 25 to reset, so that the two sealing blocks 26 reset accordingly. During this process, when the two sealing blocks 26 pass through the trapezoidal protrusions on the liquid inlet pipe 24, the cleaning liquid in the liquid storage hopper 23 will enter the second water storage cavity along the liquid inlet pipe 24 from the second connecting pipe 27 and fill the second water storage cavity, so that after the dust-proof plug 17 blocks the nozzle 7, the cleaning liquid can wet the inner wall of the nozzle 7 and soften the scale on the inner wall of the nozzle 7, facilitating the cleaning ring 20 to more conveniently scrape the scale on the inner wall of the nozzle when the water pump 2 operates next time.

[0036] Trapezoidal protrusions on the liquid inlet pipe 24 are fixedly connected with mounting blocks 28. A first cavity 29 is formed on one side of the mounting block 28 close to the water spraying plate 5, and a second cavity 32 is formed on one side of the mounting block 28 close to the liquid storage hopper 23. Both the first cavity 29 and the second cavity 32 communicate with the inner cavity of the liquid inlet pipe 24. A liquid inlet groove 37 is formed in the mounting block 28. One end of the liquid inlet groove 37 communicates with the first cavity 29, and the other end of the liquid inlet groove 37 communicates with the inner cavity of the liquid inlet pipe 24. A plugging block 31 is slidably connected in the first cavity 29. A third spring 30 is fixedly connected between the plugging block 31 and the inner wall of the first cavity 29. A support rod 33 is fixedly connected to one side of the plugging block 31 away from the third spring 30. The end of the support rod 33 away from the plugging block 31 extends into the second cavity 32 and is fixedly connected with a limiting sleeve 34. An elastic member is arranged in the limiting sleeve 34. During operation, when the water pump 2 starts to operate and the water pressure in the second water storage cavity increases, the first sealing plate 9 drives the connecting rod 25 to slide, so that the two sealing blocks 26 slide towards the liquid storage hopper 23 side accordingly. Until the dust-proof plug 17 is away from the nozzle 7, that is, when the first sealing plate 9 stops sliding, the two sealing blocks 26 block the liquid inlet pipe 24 again. During this process, when the two sealing blocks 26 pass through the mounting block 28, they will squeeze the elastic member, causing it to contract into the limiting sleeve 34. The plugging block 31 remains stationary and blocks the first cavity 29, and the cleaning liquid cannot flow through the liquid inlet groove 37 into the second water storage cavity. When the water pump 2 stops operating, the first sealing plate 9 drives the connecting rod 25 to reset, so that the two sealing blocks 26 reset accordingly. When the two sealing blocks 26 pass through the mounting block 28 on the liquid inlet pipe 24, the sealing block 26 will drive the elastic member to slide, so that the limiting sleeve 34 drives the plugging block 31 to slide through the support rod 33, and compresses the third spring 30, so that the cleaning liquid enters the first cavity 29 along the liquid inlet groove 37, then returns to the liquid inlet pipe 24 from the first cavity 29, and finally enters the second water storage cavity. Through this structure, only when the sealing block 26 resets can the cleaning liquid enter the second water storage cavity of the water spraying plate 5 to wet the inner wall of the nozzle 7, avoiding waste of the cleaning liquid caused by ineffective wetting of the inner wall of the nozzle 7.

[0037] The elastic member includes a stopper 36 and a limit block 40. The stopper 36 is slidably connected in the inner cavity of the limit sleeve 34. A spring four 35 is fixedly connected between the stopper 36 and the inner wall of the limit sleeve 34. One end of the stopper 36 away from the spring four 35 extends to the outside of the limit sleeve 34. A limit groove 38 is symmetrically provided on the inner wall of the second cavity 32. Slide grooves 39 are provided on the outer walls of both sides of the limit sleeve 34. The limit blocks 40 are symmetrically fixedly connected to the limit blocks 40 on both sides of the stopper 36. One end of the limit block 40 away from the stopper 36 extends into the limit groove 38. The limit block 40 is slidably connected to the limit groove 38 and the slide groove 39. During operation, when the sealing block 26 slides toward the side of the liquid storage hopper 23 and passes through the mounting block 28, the sealing block 26 first contacts the inclined surface of the stopper 36 and squeezes the stopper 36, so that the stopper 36 slides into the limit sleeve 34 and compresses the spring four 35. The limit block 40 moves along the limit groove 39. The vertical groove of the groove 38 slides until the sealing block 26 is separated from the block 36. Under the elastic force of the spring four 35, the block 36 is quickly reset. During this process, the blocking block 31 is stationary throughout and blocks the first cavity 29, so that the cleaning liquid cannot flow into the first cavity 29 through the liquid inlet groove 37. When the sealing block 26 passes the mounting block 28 during the resetting process, the sealing block 26 contacts the block 36. At this time, driven by the sealing block 26, the block 36 and the blocking block 31 slide toward the side of the water spray plate 5 together, the spring three 30 is compressed, and the limit block 40 slides along the oblique groove of the limit groove 38. During this process, the cleaning liquid flows into the liquid inlet groove 37 and the first cavity 29 and then enters the water storage cavity 2 of the water spray plate 5 along the liquid inlet pipe 24. When the sealing block 26 is separated from the block 36, under the elastic force of the spring three 30 and the spring four 35, the blocking block 31, the limiting sleeve 34 and the block 36 are reset.

[0038] The limiting groove 38 is formed by connecting a vertical groove and an inclined groove, and the side of the stopper 36 close to the water spray plate 5 is provided with an inclined surface; when working, the sealing block 26 drives the blocking block 31 to move and open the first cavity 29 during the return stroke to facilitate the circulation of the cleaning liquid.

[0039] A spiral groove 18 is formed on the inner wall of the annular plate 13. One end of the T-shaped rod 16 away from the dust-proof plug 17 extends into the annular plate 13 and is rotatably connected to a limiting plate 15. A second spring 14 is fixedly connected between the limiting plate 15 and the first sealing plate 9. A guiding block 19 is fixedly connected to the side wall of one end of the T-shaped rod 16 away from the dust-proof plug 17. The guiding block 19 is slidably connected in the spiral groove 18. During operation, when the dust-proof plug 17 is located inside the nozzle 7, the first spring 12 is in a natural state and the second spring 14 is in a compressed state. When the first sealing plate 9 starts to compress the first spring 12, the second spring 14 is still in a compressed state. Therefore, the dust-proof plug 17 and the T-shaped rod 16 do not slide therewith. At the same time, the annular plate 13 slides with the first sealing plate 9, causing relative sliding between the annular plate 13 and the T-shaped rod 16. Furthermore, the guiding block 19 slides along the spiral groove 18, causing the T-shaped rod 16 to drive the dust-proof plug 17 and the cleaning ring 20 to rotate. The cleaning ring 20 rotates and scrapes the inner wall of the nozzle 7. With the soaking of the cleaning liquid, it is convenient to remove the scale on the inner wall of the nozzle 7. When the first sealing plate 9 continues to slide, the T-shaped rod 16 and the dust-proof plug 17 slide away from the nozzle 7 together, and water sprays out from the nozzle 7.

[0040] An anemometer and wind vane sensor 41 is fixedly installed on the top of the mounting frame 1. A motor 42 is fixedly installed at the middle position of the mounting frame 1. The output end of the motor 42 is fixedly connected to a first gear 43. The first gear 43 is meshed with a second gear 44. The second gear 44 is fixedly installed on the water spraying pipe 4. The water spraying pipe 4 and the water supply pipe 3 are rotatably connected through a sealed bearing. During operation, the anemometer and wind vane sensor 41 senses the wind speed and wind direction of the construction site in real time, which is convenient for adjusting the water supply pressure and water supply volume of the water pump 2. And when the wind direction changes, the motor 42 drives the first gear 43 to rotate, causing the second gear 44 to drive the water spraying pipe 4 and the water spraying plate 5 to rotate, which is convenient for adjusting the water spraying direction and water spraying range of the water spraying plate 5.

[0041] The cleaning ring 20 is composed of an annular scraping plate and a plurality of scraping strips 21. The scraping strips 21 are attached to the inner wall of the nozzle 7. During operation, the cleaning ring 20 is designed in a structure of an annular scraping plate and a plurality of scraping strips 21. When the dust-proof plug 17 rotates, the scraping strips 21 rotate and scrape the inner wall of the nozzle 7. When the dust-proof plug 17 axially slides, the annular scraping plate axially cleans the inner wall of the nozzle 7.

[0042] An operation method of a dust reduction device for green building construction includes the following steps:

[0043] S1: The staff externally connects the water inlet end of the water pump 2 to a water supply device, starts the water pump 2, sends water into the water spraying pipe 4 through the water supply pipe 3. The water enters the water spraying plate 5 through the first connecting pipe 6. Since the dust-proof plug 17 blocks the nozzle 7, the water pressure in the second water storage cavity rises until the dust-proof plug 17 disengages from the nozzle 7, and water starts to spray out from the nozzle 7, realizing spray dust reduction for the building construction site.

[0044] S2: When cleaning the inner wall of the nozzle 7, fill the liquid storage hopper 23 with cleaning liquid, stop the operation of the water pump 2, and the first sealing plate 9 and the second sealing plate 10 drive the dust-proof plug 17 to reset. During this process, the cleaning liquid in the liquid storage hopper 23 enters the second water storage cavity along the liquid inlet pipe 24 and the second connecting pipe 27, so as to wet and soften the scale on the inner wall of the nozzle 7. Then start the water pump 2 again. The first sealing plate 9 drives the dust-proof plug 17 to disengage from the nozzle 7 again. At the same time, the cleaning ring 20 cleans the softened scale on the inner wall of the nozzle 7.

[0045] S3: The wind speed and wind direction sensor 41 senses the wind speed and wind direction of the construction site in real time, and controls the water pressure, the water spraying direction and the water spraying range of the water spraying plate 5 through the water pump 2 and the motor 42 respectively.

[0046] Working principle:

[0047] The staff connects the water inlet end of the water pump 2 to an external water supply device. Through the cooperation of the water pump 2 and the water delivery pipe 3, water is continuously sent into the water spray pipe 4. The water in the water spray pipe 4 enters the first water storage cavity formed by the fixed plate 8 and the water spray plate 5 through the first connecting pipe 6, and then enters the second water storage cavity formed by the second sealing plate 10 and the water spray plate 5 through the water inlet pipe 11. At this time, since the dust-proof component blocks the spray head 7, the water entering the second water storage cavity cannot be sprayed out from the spray head 7. The water pressure in the second water storage cavity continuously increases until it drives the first sealing plate 9 and the second sealing plate 10 to slide and compress the first spring 12. At the same time, the dust-proof component slides away from the spray head 7 and cleans the scale on the inner wall of the spray head 7. The water begins to be sprayed out from the spray head 7 for spray dust reduction of the construction site. When the dust reduction is completed, the water pump 2 stops working, and the water pressure in the second water storage cavity begins to drop. The first sealing plate 9 and the second sealing plate 10 reset under the elastic force of the first spring 12 and drive the dust-proof component to block the spray head 7 again. When the water pump 2 starts working and the water pressure in the second water storage cavity increases, the first sealing plate 9 drives the connecting rod 25 to slide, causing the two sealing blocks 26 to slide towards the liquid storage hopper 23 until the dust-proof plug 17 is away from the spray head 7, and the first sealing plate 9 stops sliding. At this time, the two sealing blocks 26 block the liquid inlet pipe 24 again. During this process, the two sealing blocks 26 pass through the mounting block 28, the sealing block 26 contacts the inclined surface of the stop block 36, and squeezes the stop block 36, causing the stop block 36 to slide into the limit sleeve 34 and compress the fourth spring 35. The limit block 40 slides along the vertical groove of the limit groove 38 until the sealing block 26 disengages from the stop block 36. Under the elastic force of the fourth spring 35, the stop block 36 quickly resets, while the blocking block 31 remains stationary throughout and blocks the first cavity 29, preventing the cleaning liquid from flowing into the first cavity 29 through the liquid inlet groove 37. When the water pump 2 stops working again, the first sealing plate 9 drives the connecting rod 25 to reset, causing the two sealing blocks 26 to reset. During this process, when the two sealing blocks 26 pass through the mounting block 28 on the liquid inlet pipe 24, the sealing block 26 contacts the stop block 36 again. Driven by the sealing block 26, the stop block 36 and the blocking block 31 slide towards the water spray plate 5 together, the third spring 30 is compressed, and the limit block 40 slides along the inclined groove of the limit groove 38 accordingly. The cleaning liquid flows into the liquid inlet groove 37 and the first cavity 29 and then enters the second water storage cavity of the water spray plate 5 along the liquid inlet pipe 24. When the sealing block 26 disengages from the stop block 36, under the elastic force of the third spring 30 and the fourth spring 35, the blocking block 31, the limit sleeve 34 and the stop block 36 reset accordingly. Through this structure, only when the sealing block 26 resets can the cleaning liquid enter the second water storage cavity of the water spray plate 5 to wet the inner wall of the spray head 7. When the dust-proof plug 17 is inside the spray head 7, the first spring 12 is in a natural state, and the second spring 14 is in a compressed state. When the first sealing plate 9 starts to compress the first spring 12, the second spring 14 is still in a compressed state, the dust-proof plug 17 and the T-shaped rod 16 are stationary. At the same time, since the annular plate 13 slides with the first sealing plate 9, the relative sliding between the annular plate 13 and the T-shaped rod 16 causes the guide block 19 to start sliding along the spiral groove 18.Thus, the T-shaped rod 16 drives the dust-proof plug 17 and the cleaning ring 20 to rotate, realizing the rotational scraping of the inner wall of the nozzle 7 by the cleaning ring 20. Combined with the soaking of the cleaning liquid, it is convenient to remove the scale on the inner wall of the nozzle 7. When the first sealing plate 9 continues to slide, the T-shaped rod 16 and the dust-proof plug 17 slide away from the nozzle 7 together, and water sprays out from the nozzle 7. The wind speed and direction sensor 41 senses the wind speed and direction of the construction site in real time, facilitating the adjustment of the water supply pressure and water supply volume of the water pump 2. When the wind direction changes, the motor 42 drives the first gear 43 to rotate, and drives the second gear 44 to drive the water spray pipe 4 and the water spray plate 5 to rotate, facilitating the adjustment of the water spray direction and water spray range of the water spray plate 5.
