Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, specifically to a dust reduction device for engineering construction. Background Technology
[0002] Construction refers to the process of transforming an engineering project from a design scheme into a physical structure or facility through a series of organized and planned manual and mechanical operations, in accordance with engineering design drawings, technical specifications, and contract requirements. It is a crucial implementation phase in engineering project construction, directly determining the project's quality, schedule, cost, and safety.
[0003] With the rapid development of cities, a large number of construction projects are being carried out in the city. These construction projects generate a lot of dust, which will pollute the urban environment if not treated. Therefore, existing technologies generally use dust reduction devices to settle dust during construction.

For example, a search revealed a dust reduction device for engineering construction disclosed in Chinese patent application CN218901194U. The overall structure of this device is designed to be foldable, and the shape can be changed according to the actual application to meet the needs of operation and storage. The dust suppression net can effectively intercept the spread of dust when unfolded, and the spray nozzle can effectively accelerate the landing of flying dust. The addition of folding legs, fixed sleeves, and casters makes the device structure more flexible and convenient to use, store, and move.
[0005] However, in actual use, in order to achieve the effect of reducing dust, engineering construction needs to be carried out inside the bow-shaped frame of the device, which affects the progress of the project. Furthermore, the construction process requires the use of engineering machinery, and the installation of dust suppression nets on the top of multiple bow-shaped frames seriously affects the operation of the engineering machinery.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model provides a dust reduction device for engineering construction. By setting up a water storage tank inside the enclosure, rainwater can be collected. The water is pumped into the tank body by a water pump. Then, the sliding block moves up and down repeatedly by a drive component. At the same time, the drive component can also make the threaded block slide back and forth, thereby driving the tank body to move back and forth. This allows the nozzle to move up and down and left and right during the spraying process, making the spraying range of the nozzle wider and reducing dust in the environment without affecting the use of construction machinery. 2. This utility model discloses a dust reduction device for engineering construction. By symmetrically arranging sealing plates on the top of the collection box, the sealing plates can be rotated appropriately during rain to create a gap between the two sealing plates. At the same time, the surface of the sealing plates is inclined so that rainwater dripping onto the surface of the sealing plates can fall through the gap and be filtered by the first and second filter plates before being collected inside the main body of the box by a water pump. In sunny weather, the two sealing plates seal the collection box to prevent rainwater evaporation and make better use of water resources. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] This utility model provides, for example Figures 1-5 The dust reduction device for engineering construction shown includes a ground 1, and a fence 2 is fixedly connected to the top of the ground 1. The interior of fence 2 is equipped with a storage mechanism 3 for storing rainwater; like Figures 4-5 As shown, the storage mechanism 3 includes a water storage tank 31. The bottom of the water storage tank 31 is fixedly connected to the top of the ground. At the same time, the outer wall of the water storage tank 31 is in contact with the inner wall of the fence 2. The inner wall of the water storage tank 31 is provided with multiple collection boxes 32 for collecting rainwater.
[0022] To prevent rainwater from evaporating from inside the water storage tank 31, such as Figure 5 As shown, symmetrical sealing plates 33 are arranged on the top of the inside of the collection box 32. The top and bottom of the sealing plates 33 are inclined surfaces. At the same time, a damping shaft is inserted into one end of the sealing plate 33. The two ends of the damping shaft are rotatably connected to the inside of the collection box 32 through bearings. When it rains, rainwater can rotate the sealing plates 33 appropriately, so that there is a certain gap between the two sealing plates 33. The inclined surface of the sealing plate 33 allows rainwater to drip into the gap. In sunny weather, the two sealing plates 33 seal the collection box 32, preventing the evaporation of rainwater and making good use of water resources.
[0023] To increase the spraying range, a spraying mechanism 4 is installed on the top of the water storage tank 31 to spray rainwater.
[0024] like Figures 2-3As shown, the spraying mechanism 4 includes two symmetrically arranged slide rails 42. The bottom of the slide rails 42 is fixedly connected to the top of the water storage tank 31. A gearbox 41 is fixedly connected to the top of the slide rails 42. A drive assembly 47 is provided inside the gearbox 41. A sliding block 45 is slidably connected inside the slide rails 42. A spray box 44 is provided on the top of the sliding block 45.
[0025] When dust reduction is required, the drive assembly 47 enables the sliding block 45 to move up and down and the spray box 44 to move left and right, allowing the nozzles to reciprocate up, down, left, and right during spraying, thus widening the spraying range. Figure 3 As shown, the drive assembly 47 includes a threaded rod 471 located inside the slide rail 42. The two ends of the threaded rod 471 are connected to the inside of the slide rail 42 via bearings. The surface of the threaded rod 471 is threadedly connected to the inside of the sliding block 45. A servo motor 475 is fixedly connected inside the gearbox 41. The output end of the servo motor 475 is fixedly connected to the surface of one of the threaded rods 471. When it is necessary to reduce dust, the operator starts the servo motor 475. The start of the servo motor 475 can drive the threaded rod 471 connected to it to rotate. After the threaded rod 471 rotates for a period of time, the servo motor 475 causes the threaded rod 471 to rotate in the opposite direction.
[0026] Meanwhile, a first bevel gear 472 and a third bevel gear 476 are respectively fixedly sleeved on the surfaces of the two threaded rods 471. A lead screw 474 is installed inside the gearbox 41, with a second bevel gear 473 and a fourth bevel gear 477 respectively sleeved at both ends. The surfaces of the first bevel gear 472 and the third bevel gear 476 mesh with the second bevel gear 473 and the fourth bevel gear 477 respectively. A threaded block 478 is threaded onto the surface of the lead screw 474. Multiple first hydraulic telescopic rods 46 are fixedly connected to the top of the gearbox body 441. The top of the retractor 46 is fixedly connected to the bottom of the threaded block 478. When one of the threaded rods 471 rotates, it can cause the third bevel gear 476 to rotate. The rotation of the third bevel gear 476 can cause the fourth bevel gear 477 to rotate. The rotation of the fourth bevel gear 477 can cause the lead screw 474 to rotate. The rotation of the lead screw 474 can cause the second bevel gear 473 to rotate. The rotation of the second bevel gear 473 can cause the first bevel gear 472 to rotate. The rotation of the first bevel gear 472 can cause the other threaded rod 471 to rotate, thereby causing the sliding block 45 to slide.
[0027] During the rotation of the lead screw 474, the threaded block 478 can move, and the movement of the threaded block 478 can drive the first hydraulic telescopic rod 46 to move, and the movement of the first hydraulic telescopic rod 46 can move the spray box 44.
[0028] It should be noted that during the upward movement of the sliding block 45, the first hydraulic telescopic rod 46 can be compressed, and conversely, the first hydraulic telescopic rod 46 can be stretched, making the movement of the sliding block 45 more stable.
[0029] To facilitate the movement of the first hydraulic telescopic rod 46, a through groove is provided at the bottom of the gearbox 41. This is to prevent the sprayed water from affecting the internal mechanical components of the gearbox 41. Figure 3 As shown, the spray box 44 includes a box body 441, which is slidably connected to the top of the sliding block 45. The outer wall of the box body 441 is provided with a plurality of extension tubes 442, one end of which is threadedly connected to a nozzle. Meanwhile, a baffle 43 is fixedly connected to the outer wall of the gear box 41. This utility model can extend the spraying position of the nozzle through the extension tubes 442 and block the water outside the gear box 41 through the baffle 43.
[0030] In order to limit the sliding block 45, a plurality of second hydraulic telescopic rods 48 are fixedly connected to the top of the water tank 31. The top of the second hydraulic telescopic rods 48 is fixedly connected to the bottom of the sliding block 45. When the sliding block 45 slides upward, the second hydraulic telescopic rods 48 will be stretched, further making the movement of the sliding block 45 more stable.
[0031] To prevent nozzle clogging, such as Figure 3 , Figure 5 As shown, a first filter plate 34 is fixedly connected inside the collection tank 32. The first filter plate 34 can filter impurities in the rainwater. A second filter plate 35 is fixedly connected inside the collection tank 32. A water supply pipe located below the second filter plate 35 is provided on the outer wall of the collection tank 32. A water pump 49 is fixedly connected to the outer wall of the tank body 441. The input end of the water pump 49 is connected to the flange of the water supply pipe. When the water pump 49 is started, in order to allow the water inside the water storage tank 31 to enter the water supply pipe, the impurities in the water will be filtered again by the second filter plate 35, so that the water pumped by the water pump 49 is clean. The output end of the water pump 49 is connected to a connecting water pipe through a flange. The two ends of the connecting water pipe are connected to the tank body 441, so the water will be pumped into the tank body 441 and finally sprayed out through the nozzle.
[0032] It should be noted that because the sliding block 45 needs to be raised and lowered, the water supply pipe is a corrugated pipe.
[0033] It should also be noted that the surface of the water storage tank 31 has multiple openings located on the top of the second filter plate 35. During the water storage process, the openings are blocked by plugs to prevent rainwater from flowing out. When there is less rainwater inside the water storage tank 31, the plugs can be removed and the impurities located on the top of the second filter plate 35 can be removed using tools.
[0034] Finally, it should be noted that the construction work is located inside the fence. When construction machinery is needed, it can be driven in through the gap in the fence. Compared with the existing technology in the background document, it will not affect the use of construction machinery.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
