Description

Technical Field

[0001] The invention relates to the field of building construction, and more specifically, to a dust reduction system for cast-in-place integral reinforced concrete construction. Background Art

[0002] With the development of my country's economy and society, high-rise buildings, roads, railways, subways, airports, urban underground transportation facilities, etc. are constantly being built in various places, and there are more and more construction sites. Since many construction sites are located in densely populated areas, they bring dust pollution to surrounding residents or pedestrians, reduce people's quality of life, and endanger people's health. Therefore, during the construction process, it is usually necessary to carry out regular dust reduction treatment on the construction site.

[0003] In the prior art, a Chinese patent with publication number CN108487927A discloses a movable construction spray dust suppression device, including a spray recovery box, a spray device, a telescopic cylinder, a rotating support, a bottom support, a water tank, and a spray recovery seat. A water tank is provided on the inner surface of the bottom support, a controller is electrically connected to one end of the bottom support, and a spray recovery box is provided on one side of the upper end surface of the bottom support.

[0004] The prior art realizes that the equipment can carry out dust reduction treatment on the construction site during operation through the combination of the above-mentioned components. At the same time, it can automatically collect the atomized dust and automatically filter it. The filtered water resources can be used again for dust reduction work, which is energy-saving, environmentally friendly and highly practical.

[0005] However, in the above-mentioned prior art, the spray direction of the spray device is adjusted by the extension and retraction of the telescopic cylinder, that is, the spray device is turned upside down by the extension and retraction of the telescopic cylinder to adjust the spray direction of the spray device. After the adjustment, the spray device can only spray in the set direction, and the spray range is small. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a dust reduction system for cast-in-place integral reinforced concrete construction, which has the advantage of a wide spray range.

[0007] The technical solution adopted by the present invention is implemented as follows: a dust suppression system for cast-in-place integral reinforced concrete construction, comprising a bottom support and a spray device arranged on the bottom support, the spray device comprising a hollow spray barrel, the spray barrel comprising an air inlet and a spray outlet, the spray outlet of the spray barrel being provided with a mist reversing barrel, one end of the mist reversing barrel being rotatably connected to the spray barrel, and the spray barrel being provided with a driving device for driving the mist reversing barrel to rotate;

[0008] A shutter is arranged at one end of the mist reversing cylinder away from the spray cylinder, and a linkage mechanism for driving the shutter to swing is arranged on the mist reversing cylinder.

[0009] By adopting the above technical scheme, during dust reduction, mist is sprayed out from the spray barrel, and during the spraying process, the linkage mechanism drives the louver to move so that the louver swings relative to the spray reversing barrel to change the spraying direction of the airflow, thereby changing the spraying direction of the spray barrel; at the same time, during the spraying process, the mist reversing barrel is driven to rotate by the driving device, and when the mist reversing barrel rotates, the louver rotates with the mist reversing barrel, that is, during the spraying process, the louver both swings and rotates with the mist reversing barrel, thereby changing the spraying direction of the mist, and by continuously changing the spraying direction of the mist, the spraying range of the mist is increased, so that the spraying range is wider.

[0010] As a further improvement of the present invention, the driving device includes a transmission wheel rotatably arranged in the spray cylinder and a driving motor for driving the transmission wheel to rotate, the output shaft of the driving motor is connected to the transmission shaft, the transmission wheel is connected to the transmission shaft, and a transmission mechanism is connected between the transmission wheel and the mist reversing cylinder.

[0011] By adopting the above technical solution, the driving motor drives the transmission shaft to rotate, and then drives the transmission wheel to rotate. The transmission wheel and the mist reversing cylinder are transmitted through the transmission mechanism, so that when the transmission wheel rotates, it can drive the mist reversing cylinder to rotate, thereby changing the spray direction of the mist.

[0012] As a further improvement of the present invention, the transmission mechanism includes a driving gear sleeved on the transmission wheel and a driven gear meshingly connected to the driving gear, the side wall of the spray cylinder is provided with a makeshift groove for one side of the driven gear to pass through the spray cylinder, and the inner wall of the mist reversing cylinder is provided with an annular rack meshingly connected to the driven gear.

[0013] By adopting the above technical solution, the transmission wheel and the mist reversing cylinder are connected through the meshing connection of the driving gear, the driven gear and the annular rack to achieve transmission, making the transmission process more stable.

[0014] As a further improvement of the present invention, the shutter comprises a plurality of blades arranged in parallel, and the plurality of blades are rotatably arranged at one end of the mist reversing cylinder away from the spray cylinder;

[0015] The linkage mechanism comprises a linkage rod movably arranged on the mist reversing cylinder along the radial direction of the mist reversing cylinder, the two ends of the linkage rod respectively pass through the two sides of the mist reversing cylinder, the linkage rod is perpendicular to the blades, and a plurality of blades are connected to the linkage rod;

[0016] A connecting rod perpendicular to the connecting rod is provided at one end of the linkage rod, and one end of the connecting rod extends to the side wall of the spray barrel. A sliding rod is provided at the end of the connecting rod extending to the spray barrel, and a sliding groove is provided on the side wall of the spray barrel along the circumference of the spray barrel. One end of the sliding rod abuts against the bottom of the sliding groove and slides in the sliding groove; raised portions are provided at intervals in the sliding groove, and the end of the sliding rod abuts against and slides against the raised portions.

[0017] By adopting the above technical solution, during the rotation of the mist reversing cylinder, the connecting rod rotates with the rotation of the mist reversing cylinder, thereby driving the connecting rod to rotate circumferentially around the spray cylinder. During the rotation of the connecting rod, the slide bar slides relative to the slide groove. When the slide bar slides to the position of the protruding portion, a gap is formed between the protruding portion and the bottom of the slide groove, so that the slide bar is lifted up when it hits the protruding portion, thereby driving the connecting rod to be lifted up, and then driving the connecting rod to slide relative to the mist reversing cylinder. During the sliding process of the connecting rod, the shutter is driven to swing, thereby changing the spray direction.

[0018] As a further improvement of the present invention, the sliding rod is slidably fitted into one end of the sliding groove to form an arc transition.

[0019] By adopting the above technical solution, the sliding bar can slide more smoothly relative to the sliding groove.

[0020] As a further improvement of the present invention, a limiting block is provided at one end of the linkage rod away from the connecting rod.

[0021] By adopting the above technical solution, a limiting block is added to limit the linkage rod, thereby preventing the linkage rod from being separated from the mist reversing cylinder.

[0022] As a further improvement of the present invention, a spring is sleeved on one end of the linkage rod away from the connecting rod, one end of the spring is connected to the side wall of the mist reversing cylinder, and the other end is connected to the limit block.

[0023] By adopting the above technical solution, a spring is added to facilitate resetting the linkage rod, so that the linkage rod can be reset after driving the blade to swing.

[0024] As a further improvement of the present invention, both the air inlet and the spray outlet of the spray barrel are provided with turbines, and the axle of the worm gear is connected to the transmission shaft.

[0025] By adopting the above technical solution, turbines are arranged at the air inlet and the spray outlet of the spray barrel. At the same time, the transmission shaft is connected to the turbine, so that the driving motor can drive the two turbines to rotate while driving the mist reversing barrel to rotate, thereby enhancing the wind force in the mist barrel.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. During the spraying process, the shutter swings and rotates with the mist reversing cylinder to change the spraying direction of the mist. By constantly changing the spraying direction of the mist, the spraying range of the mist is increased, making the spraying range wider;

[0028] 2. During the rotation of the mist reversing cylinder, the linkage rod rotates with the rotation of the mist reversing cylinder, thereby driving the connecting rod to rotate around the circumference of the spray cylinder. During the rotation of the connecting rod, the slide bar slides relative to the slide groove. When the slide bar slides to the position of the protrusion, due to the displacement difference between the protrusion and the bottom of the slide groove, the slide bar is lifted up when it hits the protrusion, thereby driving the connecting rod to be lifted up, and then driving the linkage rod to slide relative to the mist reversing cylinder. During the sliding process of the linkage rod, the shutter is driven to swing, thereby changing the spray direction. BRIEF DESCRIPTION OF THE DRAWINGS

The outer diameter of the spray barrel 4 gradually decreases from the air inlet 41 to the spray outlet 42. Mounting seats 5 are symmetrically welded on both sides of the spray barrel 4, and a rotating shaft 6 is rotatably connected to the mounting seat 5. The rotating shaft 6 is arranged horizontally, and one end of the rotating shaft 6 is fixedly connected to the rotating frame 3. The rotating frame 3 and the mounting seat 5 are connected by the rotating shaft 6, so that the spray barrel 4 can be turned upside down.

[0040] like Figure 2 As shown, the mist reversing cylinder 13 also includes a large mounting cylinder 132, which is connected to one end of the small mounting cylinder 131 facing the air inlet 41 of the spray cylinder 4. The inner diameter of the large mounting cylinder 132 is larger than the outer diameter of the spray outlet 42 of the spray cylinder 4, and a gap is formed between the inner wall of the large mounting cylinder 132 and the side wall of the spray cylinder 4.

[0041] like Figure 2 As shown, an annular rack 1321 is installed on the inner wall of one end of the large installation cylinder 132 away from the small installation cylinder 131 , and the annular rack 1321 is arranged along the circumference of the large installation cylinder 132 .

[0042] Combination Figure 3 The side wall of the spray barrel 4 is provided with four clearance grooves 44 penetrating the inner wall of the spray barrel 4, and the four clearance grooves 44 are evenly spaced along the circumference of the spray barrel 4. A driven gear 141 is rotatably carried in each clearance groove 44, and both upper and lower sides of the driven wheel protrude from the clearance groove 44, that is, one side of the driven wheel protrudes to the gap between the large mounting cylinder 132 and the side wall of the spray barrel 4, and is meshed and connected with the annular rack 1321, and the other side protrudes into the spray barrel 4.

[0043] like Figure 2 and Figure 3 As shown, a ring-shaped transmission wheel 142 is rotatably installed in the spray barrel 4, and a driving gear 143 is sleeved on the outer side of the transmission wheel 142. The driving gear 143 is meshed and connected with a side of the driven gear 141 protruding into the spray barrel 4. In this embodiment, a transmission frame 144 is fixedly installed on the transmission shaft 11 in the spray barrel 4, and the transmission frame 144 is fixedly connected to the inner side of the transmission wheel 142, so that the driving motor 10 drives the transmission shaft 11 to rotate, so that when the two turbines 8 rotate, the transmission wheel 142 can be driven to rotate at the same time, so that the driving gear 143 rotates, and the driving gear 143 and the annular rack 1321 of the large installation barrel 132 are driven by the driven gear 141, so that the mist reversing barrel 13 rotates.

[0044] like Figure 4 As shown, a louver 15 is movably installed in the small mounting tube 131 of the mist reversing tube 13. The louver 15 includes a plurality of rotating shafts 151 rotatably installed in the small mounting tube 131 and blades 152 connected to the rotating shafts 151. In this embodiment, a plurality of rotating shafts 151 are installed in parallel in the small mounting tube 131, and one side of the blade 152 is fixedly connected to the rotating shaft 151, so that when the rotating shaft 151 rotates, it can drive the blade 152 to swing, thereby changing the spraying direction of the mist.

[0045] In addition, if Figure 4As shown, a linkage mechanism for driving the blades 152 to swing is also installed on the mist reversing cylinder 13. Specifically, the linkage mechanism includes a linkage rod 161 movably installed on the small installation cylinder 131, the linkage rod 161 passes through the small installation cylinder 131 along the radial direction of the small installation cylinder 131, the linkage rod 161 is perpendicular to the rotating shaft 151, and the linkage rod 161 can slide relative to the small installation cylinder 131 along its own length direction.

[0046] like Figure 4 As shown, the blade 152 is connected to one side of the rotating shaft 151 and is integrally formed with a connecting piece 153, and the connecting piece 153 is hinged to the connecting rod 161. By pulling the connecting rod 164 to slide along its own length direction, the connecting piece 153 can be moved along with the connecting rod 161, thereby causing the blade 152 to swing. In this embodiment, the two ends of the connecting rod 161 respectively pass through the side wall of the small installation tube 131, and one end is connected to the limiting block 162, and a spring 163 is arranged between the limiting block 162 and the side wall of the small installation tube 131. The spring 163 is sleeved on the connecting rod 161, and one end of the spring 163 is connected to the side wall of the small installation tube 131, and the other end is connected to the side wall of the limiting block 162.

[0047] In addition, if Figure 4 As shown, one end of the linkage rod 161 away from the stop block 162 is connected to a connecting rod 164, the connecting rod 164 is perpendicular to the linkage rod 161, and the connecting rod 164 is arranged along the cylinder center direction of the small installation cylinder 131. One end of the connecting rod 164 away from the linkage rod 161 extends toward one side of the large installation cylinder 132, and penetrates into the gap formed between the large installation cylinder 132 and the spray cylinder 4.

[0048] like Figure 4 and Figure 5 As shown, one end of the connecting rod 164 extending into the gap is connected to a slide rod 165, and a slide groove 45 for slidingly cooperating with the slide rod 165 is provided on the side wall of the spray barrel 4 along the circumference of the spray barrel 4. In this embodiment, one end of the slide rod 165 away from the connecting rod 164 contacts and slides with the bottom of the slide groove 45, and at the same time, one end of the slide rod 165 contacts the slide groove 45 to form an arc transition, so that the slide rod 165 is more stable when sliding relative to the slide groove 45.

During the rotation of the slide rod 165 relative to the slide groove 45, the slide rod 165 moves from the low side of the guide surface 461 to the high side, so that the slide rod 165 is lifted by the protrusion. When the slide rod 165 is lifted, it drives The connecting rod 164 moves, thereby driving the linkage rod 161 to slide along its own length direction and compress the spring 163. During the sliding process of the linkage rod 161, the shutter 15 is driven to swing, thereby changing the spray direction; and when the slide rod 165 rotates relative to the slide groove 45 to separate from the high-position side of the guide surface 461, the spring 163 drives the linkage rod 161 to reset under the action of the restoring force, thereby driving the end of the slide rod 165 to contact the bottom of the slide groove 45 again, and in the process of resetting, the linkage rod 161 drives the shutter 15 to swing again, thereby changing the spray direction again.

[0050] The overall working process: when dust is falling, mist is sprayed from the spray barrel 4. During the spraying process, the driving motor 10 drives the transmission shaft 11 to rotate, thereby rotating the mist reversing barrel 13. When the mist reversing barrel 13 rotates, the linkage rod 161 is driven to rotate. Since the connecting rod 164 is connected to the linkage rod 161, the connecting rod 164 and the slide bar 165 are driven to rotate along the circumferential direction of the spray barrel 4 during the rotation of the linkage rod 161. When the slide bar 165 rotates to the position of the protruding portion 46, the slide bar 165 moves from the low side of the guide surface 461 to the high side, so that the slide bar 165 is lifted by the protruding block. When the slide bar 165 is lifted, the connecting rod 164 is driven to move. , thereby driving the linkage rod 161 to slide along its own length direction and compress the spring 163. During the sliding process of the linkage rod 161, the shutter 15 is driven to swing, thereby changing the spray direction; and when the slide rod 165 rotates relative to the slide groove 45 to separate from the high-position side of the guide surface 461, the spring 163 drives the linkage rod 161 to reset under the action of the restoring force, thereby driving the end of the slide rod 165 to contact the bottom of the slide groove 45 again, and in the process of resetting, the linkage rod 161 drives the shutter 15 to swing again, thereby changing the spray direction again, and this cycle is repeated, so that during the spraying process, the spray direction of the mist is constantly changing, thereby expanding the spray range.
