Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction devices, and particularly to a spray dust reduction device for a temporary building enclosure. Background Art

[0002] With the rapid development of the urbanization process, the number of construction projects is increasing day by day. During the construction process, a large amount of dust is generated. These dusts not only affect air quality, but also pose a serious threat to the surrounding environment and the physical health of residents. According to relevant research, the dust generated at construction sites is one of the important sources of urban air pollution. The inhalable particulate matter and fine particulate matter and other pollutants generated are likely to cause respiratory diseases, cardiovascular diseases, etc., and are extremely harmful to human health.

[0003] The patent with the publication number CN220736891U relates to a spray dust reduction device, including a base. The top of the base is rotatably connected with a turntable. An adjustment structure is arranged on the top of the turntable. A first gear is fixedly installed at the bottom of the turntable. A fixed box is fixedly installed at the bottom of the base. A first motor is fixedly installed inside the fixed box. A second gear is fixedly installed on the output shaft of the first motor. For this spray dust reduction device, by setting the adjustment structure, the first motor drives the second gear to rotate, so that the first gear meshing with the second gear rotates and drives the turntable to rotate, thereby realizing the adjustment of the horizontal direction angle of the spray dust reduction device. This device drives a threaded rod to rotate through a second motor, and further enables the fixed plate to move up and down outside the fixed column, thereby realizing the adjustment of the height of the fog cannon machine on the spray dust reduction device in the vertical direction, making the angle of the spray dust reduction device adjustable in multiple aspects and more convenient to use. However, during the process of spraying water mist, this device can only perform dust reduction spraying in a single direction. When it is necessary to change the direction, the device needs to be manually rotated, so it is very inconvenient. Therefore, a spray dust reduction device for a temporary building enclosure is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a spray dust reduction device for a temporary building enclosure in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a spray dust suppression device for a temporary construction fence, including a box shell. A water baffle is fixedly connected to the top of the box shell. An adjustment device is arranged on the top of the box shell. A dredging device is arranged at the front of the water baffle. A braking device is arranged on the left side of the box shell. The adjustment device includes a motor, a rotating shaft, a rotating frame, a convex ring, a water tank, a rotating rod, a water sprayer, a fixed ring, an L-shaped plate one, and an L-shaped elastic telescopic plate. The motor is fixedly connected to the inner wall of the box shell. The rotating shaft is fixedly connected to the output end of the motor. The rotating frame is fixedly connected to the circumferential surface of the rotating shaft. The convex ring is fixedly connected to the top of the box shell. The water tank is fixedly connected to the inner wall of the box shell. The rotating rod is rotatably connected to the inner wall of the rotating frame. The water sprayer is rotatably connected to the circumferential surface of the rotating rod. The fixed ring is fixedly connected to the circumferential surface of the rotating rod. The L-shaped plate one is fixedly connected to the circumferential surface of the fixed ring. The L-shaped elastic telescopic plate is fixedly connected to the circumferential surface of the fixed ring. The circumferential surface of the rotating shaft is rotatably connected to the inner wall of the box shell. The bottom of the rotating frame is in contact with the top of the box shell. The bottom of the L-shaped plate one is in contact with the top of the convex ring. The telescopic end of the L-shaped elastic telescopic plate is in contact with the top of the convex ring. A water pump is arranged on the left side of the water tank. One side of the water pump away from the water tank is connected to the water sprayer through a water pipe. When starting the dust suppression work, the device is pushed to the area with thick dust through the handrail. After filling the water tank with water, the direction of the water sprayer can be adjusted, which can improve the flexibility of the device, avoid manual adjustment, and also improve the coverage range of the dust, improve the dust suppression effect of the device. At the same time, the rotation of the rotating rod drives the rotation of the water sprayer, so that the water sprayer swings up and down during the water spraying process, which can further improve the coverage effect of the water sprayer on the dust and further improve the dust suppression effect of the device.

[0006] Preferably, the dredging device includes a fixing plate, a filter plate, an arc plate, and a cleaning roller. The fixing plate is fixedly connected to the front of the water baffle. The filter plate is fixedly connected to the inner wall of the box shell. The arc plate is fixedly connected to the rear of the rotating frame. The cleaning roller is rotatably connected to the inner wall of the fixing plate. The dredging device further includes a transmission wheel, an L-shaped plate II, and a pushing plate. The transmission wheel is fixedly connected to the central shaft of the cleaning roller. The L-shaped plate II is fixedly connected to the bottom of the arc plate. The pushing plate is fixedly connected to the bottom of the L-shaped plate II. The top of the filter plate is in contact with the bottom of the pushing plate. The circumferential surface of the transmission wheel is in contact with the rear of the arc plate. During the process of water spraying for dust reduction, the rotation of the rotating frame drives the rotation of the arc plate. During the rotation of the arc plate, it will contact the transmission wheel. Thus, when the water sprayer rotates for rotation adjustment, the cleaning roller will clean the water spray nozzles on the surface of the water sprayer, avoiding the blockage of the water spray nozzles of the water sprayer caused by poor water quality of the used water source, which contains a large amount of sediment, impurities and other substances. At the same time, when cleaning the water sprayer, the rotation of the L-shaped plate II drives the rotation of the pushing plate, so that the dust, sand and other impurities falling on the surface of the filter plate can be scraped off, and further the water flow can be prevented from being blocked due to the blockage of the filter plate and unable to circulate.

[0007] Preferably, the braking device includes a fixing block, an inclined plate, a straight rod, a support plate, and a transmission spring. The fixing block is fixedly connected to the left side of the box shell. The inclined plate is fixedly connected to the front of the arc plate. The straight rod is slidably connected to the inner wall of the fixing block. The support plate is fixedly connected to the bottom of the straight rod. The transmission spring is sleeved on the circumferential surface of the straight rod. The braking device further includes an inclined block, a groove plate, an elastic telescopic block, and a pushing block. The inclined block is fixedly connected to the top of the straight rod. The groove plate is fixedly connected to the left side of the box shell. The elastic telescopic block is fixedly connected to the inner wall of the straight rod. The pushing block is fixedly connected to the telescopic end of the elastic telescopic block. The bottom of the transmission spring is fixedly connected to the top of the support plate. The top of the transmission spring is fixedly connected to the bottom of the fixing block. The top of the support plate is in contact with the bottom of the box shell. The telescopic end of the elastic telescopic block is in contact with the left side of the groove plate. During the adjustment process, the movement of the straight rod drives the movement of the support plate, so that the device can be fixed during the water spraying process, avoiding the situation that the dust reduction device moves due to the reaction force of the water spray generated during the dust reduction work, and then the device needs to be re-adjusted in angle. At the same time, the output end of the elastic telescopic block will be stuck in the inner wall of the groove plate, so that the straight rod can be limited, avoiding the reset of the straight rod due to the compression force of the transmission spring, and then the device can be stably fixed and supported.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. The spray dust suppression device for the temporary fence of the building, through the cooperation of the box shell, water baffle, motor, rotating shaft, rotating frame, bump ring, water tank, rotating rod, water sprayer, fixing ring, L-shaped plate 1, and L-shaped elastic telescopic plate. When starting the dust suppression work, the device is pushed to the area with thick dust through the handrail. After filling the water tank with water, the direction of the water sprayer can be adjusted, which can improve the flexibility of the device, avoid manual adjustment, and also improve the coverage range of dust, enhancing the dust suppression effect of the device. At the same time, the rotating rod rotates to drive the water sprayer to rotate, so that the water sprayer swings up and down during the water spraying process, further improving the coverage effect of the water sprayer on dust and thus further enhancing the dust suppression effect of the device.

[0009] 2. The spray dust suppression device for the temporary fence of the building, through the cooperation of the fixing plate, filter plate, arc plate, cleaning roller, transmission wheel, L-shaped plate 2, and push plate. During the process of water spraying for dust suppression, the rotating frame rotates to drive the arc plate to rotate. During the rotation of the arc plate, it will contact the transmission wheel. Thus, when the water sprayer rotates for rotation adjustment, the cleaning roller will clean the water spray nozzles on the surface of the water sprayer, preventing the water source from having poor quality, containing a lot of sediment, impurities and other substances, which may cause blockage of the water spray nozzles of the water sprayer. At the same time, when cleaning the water sprayer, the L-shaped plate 2 rotates to drive the push plate to rotate, which can scrape off the dust, sand and other impurities falling on the surface of the filter plate, thus avoiding the blockage of the filter plate and the inability of the water flow to circulate.

[0010] 3. The spray dust suppression device for the temporary fence of the building, through the cooperation of the fixing block, inclined plate, straight rod, support plate, transmission spring, inclined block, groove plate, elastic telescopic block, and push block. During the adjustment process, the straight rod moves to drive the support plate to move, which can fix the device during the water spraying process, preventing the dust suppression device from moving due to the reaction force of the spray generated during the dust suppression work, which may require re-adjusting the angle of the device. At the same time, the output end of the elastic telescopic block will be stuck on the inner wall of the groove plate, which can limit the straight rod and prevent the straight rod from resetting due to the compression force of the transmission spring, thus stably fixing and supporting the device.

The motor 31 is fixedly connected to the inner wall of the box shell 1, the rotating shaft 32 is fixedly connected to the output end of the motor 31, the rotating frame 33 is fixedly connected to the circumferential surface of the rotating shaft 32, the convex ring 34 is fixedly connected to the top of the box shell 1, the water tank 35 is fixedly connected to the inner wall of the box shell 1, the rotating rod 36 is rotatably connected to the inner wall of the rotating frame 33, the water sprayer 37 is rotatably connected to the circumferential surface of the rotating rod 36, and the fixing ring 38 is fixedly connected to the circumferential surface of the rotating rod 36. When starting the dust reduction work, the device is pushed to the area with thick dust through the handrail, and the water tank 35 is filled with water. At this time, the motor 31 is started. The motor 31 drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the rotating frame 33 to rotate. The rotating frame 33 drives the rotating rod 36 to rotate. The rotating rod 36 drives the water sprayer 37 to rotate, so that the direction of the water sprayer 37 can be adjusted, which can improve the flexibility of the device, avoid manual adjustment, and can also improve the coverage range of dust and the dust reduction effect of the device. The L-shaped plate one 39 is fixedly connected to the circumferential surface of the fixing ring 38, the L-shaped elastic telescopic plate 310 is fixedly connected to the circumferential surface of the fixing ring 38, the circumferential surface of the rotating shaft 32 is rotatably connected to the inner wall of the box shell 1, the bottom of the rotating frame 33 is in contact with the top of the box shell 1, the bottom of the L-shaped plate one 39 is in contact with the top of the convex ring 34, and the telescopic end of the L-shaped elastic telescopic plate 310 is in contact with the top of the convex ring 34.

The L-shaped plate one 39 rotates to drive the rotating rod 36 to rotate. The rotating rod 36 rotates to drive the water sprayer 37 to rotate, so that the water sprayer 37 swings up and down during the water spraying process, which can improve the coverage effect of the water sprayer 37 on dust and further improve the dust reduction effect of the device.

[0015] The dredging device 4 includes a fixing plate 41, a filter plate 42, an arc plate 43, and a cleaning roller 44. The fixing plate 41 is fixedly connected to the front part of the water baffle 2. The filter plate 42 is fixedly connected to the inner wall of the box shell 1. The arc plate 43 is fixedly connected to the rear part of the rotating frame 33. The cleaning roller 44 is rotatably connected to the inner wall of the fixing plate 41. During the process of water spraying and dust suppression, the rotating frame 33 rotates to drive the arc plate 43 to rotate. During the rotation of the arc plate 43, it will contact the transmission wheel 45, causing a frictional force between the transmission wheel 45 and the arc plate 43 to generate self-rotation. The rotation of the transmission wheel 45 drives the cleaning roller 44 to rotate. Thus, when the water sprayer 37 rotates for rotational adjustment, the cleaning roller 44 can clean the water spray nozzles on the surface of the water sprayer 37, preventing the water source used from having poor quality, containing a large amount of sediment, impurities and other substances, which may cause blockage of the water spray nozzles of the water sprayer 37. The dredging device 4 further includes a transmission wheel 45, an L-shaped plate II 46, and a push plate 47. The transmission wheel 45 is fixedly connected to the central axis of the cleaning roller 44. The L-shaped plate II 46 is fixedly connected to the bottom of the arc plate 43. The push plate 47 is fixedly connected to the bottom of the L-shaped plate II 46. The top of the filter plate 42 is in contact with the bottom of the push plate 47. The circumferential surface of the transmission wheel 45 is in contact with the rear part of the arc plate 43. At the same time, when cleaning the water sprayer 37, the water sprayed by the water sprayer 37 will be blocked by the water baffle 2, causing the sprayed water to flow down along the inner wall of the water baffle 2. The flowing water will pass through the filter plate 42 to return the water to the water tank 35, avoiding waste of water flow. The rotation of the rotating frame 33 drives the L-shaped plate II 46 to rotate, and the rotation of the L-shaped plate II 46 drives the push plate 47 to rotate, thereby scraping off the dust, sand and other impurities that fall on the surface of the filter plate 42, and further preventing the water flow from being unable to circulate due to blockage of the filter plate 42.

[0016] Working principle: When starting the dust suppression work, the device is pushed to the area with thick dust through the handrail, and then the water tank 35 is filled with water. At this time, the motor 31 is started. The start of the motor 31 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the rotating frame 33 to rotate. The rotation of the rotating frame 33 drives the rotating rod 36 to rotate. The rotation of the rotating rod 36 drives the water sprayer 37 to rotate, so that the direction of the water sprayer 37 can be adjusted, which can improve the flexibility of the device, avoid manual adjustment, and can also increase the coverage range of dust, improve the dust suppression effect of the device. At the same time, the rotation of the rotating rod 36 drives the fixed ring 38 to rotate. The rotation of the fixed ring 38 drives the first L-shaped plate 39 to rotate. When the first L-shaped plate 39 rotates, it will contact the top of the bump ring 34. When the first L-shaped plate 39 moves to the raised part of the bump ring 34, the first L-shaped plate 39 will contact the top of the bump ring 34, causing the first L-shaped plate 39 to rotate. The rotation of the first L-shaped plate 39 drives the rotating rod 36 to rotate. The rotation of the rotating rod 36 drives the water sprayer 37 to rotate, so that the water sprayer 37 swings up and down during the water spraying process, which can further improve the dust coverage effect of the water sprayer 37 and further improve the dust suppression effect of the device.

[0017] During the process of water spraying for dust suppression, the rotation of the rotating frame 33 drives the arc-shaped plate 43 to rotate. During the rotation of the arc-shaped plate 43, it will contact the transmission wheel 45, causing the transmission wheel 45 to rotate due to the frictional force between the transmission wheel 45 and the arc-shaped plate 43. The rotation of the transmission wheel 45 drives the cleaning roller 44 to rotate. Thus, when the water sprayer 37 rotates for adjustment, the cleaning roller 44 can clean the water spray nozzles on the surface of the water sprayer 37, preventing the water source from having poor quality, containing a lot of sediment, impurities and other substances, which may cause the water spray nozzles of the water sprayer 37 to be blocked. At the same time, when cleaning the water sprayer 37, the water sprayed by the water sprayer 37 is blocked by the baffle 2, so that the sprayed water will flow down along the inner wall of the baffle 2. The flowing water will pass through the filter plate 42 and return to the water tank 35, which can avoid the waste of water flow. The rotation of the rotating frame 33 drives the second L-shaped plate 46 to rotate. The rotation of the second L-shaped plate 46 drives the push plate 47 to rotate, so that the dust, sand and other impurities falling on the surface of the filter plate 42 can be scraped off, and thus the blockage of the filter plate 42 causing the water flow to be unable to circulate can be avoided.

[0018] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, the braking device 5 includes a fixed block 51, an inclined plate 52, a straight rod 53, a support plate 54, and a transmission spring 55. The fixed block 51 is fixedly connected to the left side of the box shell 1. The inclined plate 52 is fixedly connected to the front of the arc plate 43. The straight rod 53 is slidably connected to the inner wall of the fixed block 51. The support plate 54 is fixedly connected to the bottom of the straight rod 53. The transmission spring 55 is sleeved on the circumferential surface of the straight rod 53. The braking device 5 further includes an inclined block 56, a groove plate 57, an elastic telescopic block 58, and a push block 59. The inclined block 56 is fixedly connected to the top of the straight rod 53. During the adjustment process, when the arc plate 43 rotates, it will contact the inclined block 56, causing the inclined block 56 to move downward under the extrusion force of the inclined block 56. The downward movement of the inclined block 56 drives the straight rod 53 to move downward, and the movement of the straight rod 53 drives the support plate 54 to move, so that the device can be fixed during the water spraying process, avoiding the situation that the dust reduction device moves due to the reaction force of the spray generated by the water spraying during the dust reduction work, and then the angle of the device needs to be readjusted. The groove plate 57 is fixedly connected to the left side of the box shell 1. The elastic telescopic block 58 is fixedly connected to the inner wall of the straight rod 53. The push block 59 is fixedly connected to the telescopic end of the elastic telescopic block 58. The bottom of the transmission spring 55 is fixedly connected to the top of the support plate 54, and the top of the transmission spring 55 is fixedly connected to the bottom of the fixed block 51. The top of the support plate 54 is in contact with the bottom of the box shell 1. The telescopic end of the elastic telescopic block 58 is in contact with the left side of the groove plate 57. At the same time, the movement of the straight rod 53 drives the elastic telescopic block 58 to move, and the elastic telescopic block 58 will contact the groove plate 57 during the movement. When the straight rod 53 moves down to the bottom, the elastic telescopic block 58 will reset, so that the output end of the elastic telescopic block 58 will be stuck in the inner wall of the groove plate 57, thereby limiting the straight rod 53 and avoiding the straight rod 53 from resetting due to the compression force of the transmission spring 55, and then being able to stably fix and support the device. When the support is not required after the dust reduction is completed, pull out the push block 59 to move, and the movement of the push block 59 drives the telescopic end of the elastic telescopic block 58 to be compressed, so that the limit of the straight rod 53 can be released.

[0019] Working principle: During the adjustment process, when the arc-shaped plate 43 rotates, it will contact the inclined block 56, causing the inclined block 56 to move downward under the extrusion force of the inclined block 56. The downward movement of the inclined block 56 drives the straight rod 53 to move downward, and the movement of the straight rod 53 drives the support plate 54 to move, so that the device can be fixed during the water spraying process, avoiding the situation that the dust suppression device moves due to the reaction force of the spray generated by the water spraying during the dust suppression work, and then the angle of the device needs to be adjusted again. At the same time, the movement of the straight rod 53 drives the elastic telescopic block 58 to move. During the movement of the elastic telescopic block 58, it will contact the groove plate 57. When the straight rod 53 moves to the bottom, the elastic telescopic block 58 will reset, so that the output end of the elastic telescopic block 58 will be stuck on the inner wall of the groove plate 57, thus the straight rod 53 can be limited, avoiding the straight rod 53 from resetting due to the compression force of the transmission spring 55, and then the device can be stably fixed and supported. When the support is not required after the dust suppression is completed, pull out the push block 59 to move, and the movement of the push block 59 drives the telescopic end of the elastic telescopic block 58 to be compressed, so that the limit of the straight rod 53 can be released.

The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using the prior art.
