Description

Technical Field

[0001] The utility model relates to the technical field of construction dust prevention, in particular to a building construction dust prevention device. Background Technique

[0002] During indoor construction, due to the flow of gas, the dust generated during the construction process will fly. In order to prevent the dust generated during construction from spreading to other areas and causing pollution, a dust prevention device is generally used to block the spread of dust.

[0003] There is a building construction dust prevention device with the publication number of CN214437520U. This patent adopts the settings of a fog cannon barrel and a nozzle to jointly construct a building construction dust prevention device. The cooperation of a fan, an annular pipe, a spray head, a bracket, a first connecting pipe and a first water pump can enable the fog cannon barrel to remove dust from the air. Then, through the cooperation of a chassis, a motor, a support rod, a nozzle, a second connecting pipe and a second water pump, the floating dust on the ground can be sprayed at multiple angles. The combined use of the two improves the dust removal efficiency and effectively shortens the dust removal time.

[0004] The inventor found in daily work that although the above-mentioned building construction dust prevention device can spray the floating dust on the ground at multiple angles, when the height of the floating dust is relatively high, the dust may cross the dust prevention components and spread to other areas, causing pollution, resulting in poor dust prevention effect of the device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the technical problems in the above background and propose a building construction dust prevention device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a building construction dust prevention device, including a fixed column and a water storage cylinder. A water inlet pipe is fixedly installed on the top surface of the water storage cylinder. An auxiliary device is arranged on the top surface of the water storage cylinder. The auxiliary device includes a hollow pipe. The hollow pipe is fixedly installed on the top surface of the water storage cylinder. A plurality of nozzles are evenly distributed on the outer wall surface of the hollow pipe. The top surface of the fixed column is rotatably connected with a rotating shaft. A winding roller is fixedly installed at one end of the rotating shaft away from the fixed column. A dust-proof cloth is wound on the outer wall surface of the winding roller. One end of the dust-proof cloth is fixedly connected with the hollow pipe. The setting of the dust-proof cloth plays an effect of blocking dust.

[0007] Preferably, an extraction pump is fixedly installed on the outer wall surface of the water storage cylinder. An extraction pipe is fixedly installed at the input end of the extraction pump. One end of the extraction pipe away from the extraction pump is communicated with the water storage cylinder. A discharge pipe is fixedly installed at the output end of the extraction pump. One end of the discharge pipe away from the extraction pump is communicated with the hollow pipe. The settings of the extraction pump, the extraction pipe and the discharge pipe play an effect of reducing dust.

[0008] Preferably, a vertical strip board is fixedly installed on the outer wall surface of the water storage cylinder. A vertical groove is formed on the surface of the vertical strip board. An L-shaped board is slidably connected inside the vertical groove. A pulley is fixedly installed at one end of the L-shaped board away from the vertical groove. A groove is formed on the side surface of the vertical strip board. A displacement board is slidably connected inside the groove. One end of the displacement board away from the groove is fixedly connected to the L-shaped board. A bolt is threadedly connected to the surface of the displacement board. A plurality of threaded holes are evenly formed on the side surface of the vertical strip board. The setting of the pulley plays an effect of facilitating the movement of the water storage cylinder.

[0009] Preferably, a limiting device is provided on the outer wall surface of the fixed column. The limiting device includes a sliding rod. The sliding rod is fixedly installed on the outer wall surface of the fixed column. A moving part is slidably connected to the surface of the sliding rod. A plug rod is fixedly installed on the surface of the moving part. A plurality of jacks are annularly formed on the outer wall surface of the rotating shaft. The setting of the plug rod and the jacks plays an effect of restricting the rotation of the rotating shaft.

[0010] Preferably, a strip board is fixedly installed on the surface of the sliding rod away from the fixed column. Two fixing plates are fixedly installed on the surface of the strip board. A threaded rod is rotatably connected between the two fixing plates. A motor is fixedly installed on the surface of one of the fixing plates. The output end of the motor is fixedly connected to the threaded rod. The setting of the motor plays an effect of driving the threaded rod to rotate.

[0011] Preferably, a strip groove is formed on the surface of the strip board. A movable board is threadedly connected to the surface of the threaded rod. A hinged board is hinged to the surface of the movable board. One end of the hinged board away from the movable board is hinged to the moving part. The setting of the hinged board plays an effect of driving the moving part to move on the surface of the sliding rod.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, by providing an auxiliary device, when the device needs to be used, first, the staff can manually push the water storage cylinder. The movement of the water storage cylinder causes the pulley to move. At the same time, the movement of the water storage cylinder also drives the movement of the hollow tube. The movement of the hollow tube pulls the dust-proof cloth. Then, under the action of the rotating shaft, the winding roller rotates, so that the dust-proof cloth unfolds to intercept the dust in the corresponding area. Next, loosen the bolt and screw the bolt out from the inside of the threaded hole. The separation of the bolt and the threaded hole causes the displacement plate to lose its limit in the groove. At this time, the displacement plate can be moved. The movement of the displacement plate in the groove drives the L-shaped plate to move in the vertical groove. The movement of the L-shaped plate in the vertical groove drives the pulley to move, and the pulley moves away from the ground. When the pulley moves to a suitable position, screw the bolt into the corresponding threaded hole again to fix the position of the displacement plate in the groove at this time. Finally, start the extraction pump, use the extraction pipe to transport the water in the water storage cylinder into the inside of the discharge pipe, then transport it into the inside of the hollow tube from the inside of the discharge pipe, and then transport it into the inside of the nozzle from the inside of the hollow tube, and finally spray out from the nozzle to quickly drop the floating dust. Through the cooperation of the above structures, while the device uses the dust-proof cloth to block the dust, it also uses the water mist to reduce the floating of the dust, thus solving the problem that the dust floats over the dust-proof cloth and pollutes other areas, and ensuring the dust-proof quality.

[0014] 2. In the present utility model, by providing a limiting device, when it is necessary to keep the dust-proof cloth in a taut state, first start the motor. The start of the motor drives the rotation of the threaded rod. The rotation of the threaded rod drives the movable plate to move in the strip-shaped groove. The movement of the movable plate in the strip-shaped groove drives the articulated plate to move. The movement of the articulated plate pushes the moving part to move on the surface of the sliding rod. The movement of the moving part on the surface of the sliding rod drives the insertion rod to move. The insertion rod moves and inserts itself into the inside of the insertion hole. The insertion rod and the insertion hole are inserted and connected, thereby restricting the rotation of the rotating shaft. The rotating shaft cannot rotate, so that the winding roller cannot rotate, and thus the dust-proof cloth can be kept in a taut state. Through the cooperation of the above structures, the purpose of restricting the rotation of the rotating shaft is achieved, thus avoiding the slack state of the dust-proof cloth during use and increasing the dust-proof effect of the dust-proof cloth.

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a dust-proof device for building construction, including a fixed column 1 and a water storage cylinder 2, and a water inlet pipe 3 is fixedly installed on the top surface of the water storage cylinder 2.

[0024] Next, the specific settings and functions of its auxiliary device 4 and limiting device 5 will be specifically described.

[0025] In this embodiment: an auxiliary device 4 is provided on the top surface of the water storage cylinder 2. The auxiliary device 4 includes a hollow pipe 401. The hollow pipe 401 is fixedly installed on the top surface of the water storage cylinder 2. A plurality of sprinkler heads 402 are evenly distributed on the outer wall surface of the hollow pipe 401. The top surface of the fixed column 1 is rotatably connected to a rotating shaft 403. One end of the rotating shaft 403 away from the fixed column 1 is fixedly installed with a winding roller 404. A dust-proof cloth 405 is wound on the outer wall surface of the winding roller 404. One end of the dust-proof cloth 405 is fixedly connected to the hollow pipe 401.

[0026] In this embodiment: the setting of the dust-proof cloth 405 plays an effect of blocking dust.

[0027] Specifically, a pumping pump 406 is fixedly installed on the outer wall surface of the water storage cylinder 2. An extraction pipe 407 is fixedly installed at the input end of the pumping pump 406. One end of the extraction pipe 407 far from the pumping pump 406 is communicated with the water storage cylinder 2. A discharge pipe 408 is fixedly installed at the output end of the pumping pump 406. One end of the discharge pipe 408 far from the pumping pump 406 is communicated with the hollow pipe 401.

[0028] In this embodiment: The arrangements of the pumping pump 406, the extraction pipe 407 and the discharge pipe 408 have the effect of dust suppression on the dust.

[0029] Specifically, a vertical strip plate 409 is fixedly installed on the outer wall surface of the water storage cylinder 2. A vertical groove 410 is formed on the surface of the vertical strip plate 409. An L-shaped plate 411 is slidably connected inside the vertical groove 410. A pulley 412 is fixedly installed at one end of the L-shaped plate 411 far from the vertical groove 410. A groove 413 is formed on the side surface of the vertical strip plate 409. A displacement plate 414 is slidably connected inside the groove 413. One end of the displacement plate 414 far from the groove 413 is fixedly connected to the L-shaped plate 411. A bolt 415 is threadedly connected to the surface of the displacement plate 414. A plurality of threaded holes 416 are evenly formed on the side surface of the vertical strip plate 409. The setting of the pulley 412 has the effect of facilitating the movement of the water storage cylinder 2.

[0030] In this embodiment: A limiting device 5 is provided on the outer wall surface of the fixed column 1. The limiting device 5 includes a sliding rod 501. The sliding rod 501 is fixedly installed on the outer wall surface of the fixed column 1. A moving member 502 is slidably connected to the surface of the sliding rod 501. A plug rod 503 is fixedly installed on the surface of the moving member 502. A plurality of jacks 504 are annularly formed on the outer wall surface of the rotating shaft 403. When it is necessary to keep the dust-proof cloth 405 in a taut state, first start the motor 508. The motor 508 drives the threaded rod 507 to rotate when it starts. The threaded rod 507 rotates to drive the movable plate 510 to move inside the strip-shaped groove 509. The movable plate 510 moves inside the strip-shaped groove 509 to drive the hinged plate 511 to move. The hinged plate 511 moves to push the moving member 502 to move on the surface of the sliding rod 501. The moving member 502 moves on the surface of the sliding rod 501 to drive the plug rod 503 to move. The plug rod 503 moves to insert itself into the inside of the jack 504. The plug rod 503 and the jack 504 are inserted and connected, thereby restricting the rotation of the rotating shaft 403. The rotating shaft 403 cannot rotate, so that the winding roller 404 cannot rotate, and thus the dust-proof cloth 405 can be kept in a taut state. Through the cooperation of the above structures, the purpose of restricting the rotation of the rotating shaft 403 is achieved, thereby preventing the dust-proof cloth 405 from being in a loose state during use and increasing the dust-proof effect of the dust-proof cloth 405.

[0031] Specifically, a strip-shaped plate 505 is fixedly installed on the surface of the end of the sliding rod 501 away from the fixed column 1. Two fixing plates 506 are fixedly installed on the surface of the strip-shaped plate 505. A threaded rod 507 is rotatably connected between the two fixing plates 506. A motor 508 is fixedly installed on the surface of one of the fixing plates 506, and the output end of the motor 508 is fixedly connected to the threaded rod 507.

[0032] In this embodiment: The setting of the motor 508 serves to drive the threaded rod 507 to rotate.

[0033] Specifically, a strip-shaped groove 509 is formed on the surface of the strip-shaped plate 505. A movable plate 510 is threadedly connected to the surface of the threaded rod 507. A hinge plate 511 is hinged to the surface of the movable plate 510, and one end of the hinge plate 511 away from the movable plate 510 is hinged to the moving member 502.

[0034] In this embodiment: The setting of the hinge plate 511 serves to drive the moving member 502 to move on the surface of the sliding rod 501.

[0035] Working principle: By setting the auxiliary device 4, when the device needs to be used, first, the staff can manually push the water storage cylinder 2. The movement of the water storage cylinder 2 causes the pulley 412 to move. At the same time, the movement of the water storage cylinder 2 also drives the hollow tube 401 to move. The movement of the hollow tube 401 pulls the dust-proof cloth 405. Then, under the action of the rotating shaft 403, the winding roller 404 rotates, so that the dust-proof cloth 405 unfolds to intercept the dust in the corresponding area. Then loosen the bolt 415 and screw out the bolt 415 from the inside of the threaded hole 416. The separation of the bolt 415 and the threaded hole 416 causes the displacement plate 414 to lose its limit inside the groove 413. At this time, the displacement plate 414 can be moved. The movement of the displacement plate 414 inside the groove 413 drives the L-shaped plate 411 to move inside the vertical groove 410. The movement of the L-shaped plate 411 inside the vertical groove 410 drives the pulley 412 to move, and the pulley 412 moves away from the ground. When the pulley 412 moves to a suitable position, screw the bolt 415 into the corresponding threaded hole 416 again to fix the position of the displacement plate 414 inside the groove 413 at this time. Finally, start the extraction pump 406, use the extraction pipe 407 to transport the water inside the water storage cylinder 2 into the inside of the discharge pipe 408, then transport it from the inside of the discharge pipe 408 into the inside of the hollow tube 401, and then transport it from the inside of the hollow tube 401 into the inside of the nozzle 402, and finally spray out from the nozzle 402, so that the floating dust quickly descends. Through the cooperation of the above structures, while the device uses the dust-proof cloth 405 to block the dust, it also uses water mist to reduce the floating of dust, thus solving the problem that the dust floats over the dust-proof cloth 405 and pollutes other areas, and ensuring the dust-proof quality. When it is necessary to keep the dust-proof cloth 405 in a straight state, first start the motor 508. The start of the motor 508 drives the threaded rod 507 to rotate. The rotation of the threaded rod 507 drives the movable plate 510 to move inside the strip-shaped groove 509. The movement of the movable plate 510 inside the strip-shaped groove 509 drives the hinged plate 511 to move. The movement of the hinged plate 511 pushes the moving part 502 to move on the surface of the sliding rod 501. The movement of the moving part 502 on the surface of the sliding rod 501 drives the insertion rod 503 to move. The movement of the insertion rod 503 causes itself to insert into the inside of the insertion hole 504. The insertion rod 503 and the insertion hole 504 are inserted, thus restricting the rotation of the rotating shaft 403. The rotating shaft 403 cannot rotate, so that the winding roller 404 cannot rotate, so that the dust-proof cloth 405 can be kept in a straight state. Through the cooperation of the above structures, the purpose of restricting the rotation of the rotating shaft 403 is achieved, thus avoiding the slack state of the dust-proof cloth 405 during use and increasing the dust-proof effect of the dust-proof cloth 405.
