Detailed implementation mode

[0025] In order to make the purpose, features and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model.

[0026] As Figures 1-3 shown, the present utility model provides a dust reduction device for construction engineering construction, including a moving trolley 1, a water storage tank 2, a water pump 3, a support column 4, a cantilever 5, a spraying rack 6, and a dust monitoring sensor 7; the support column 4 is erected in the middle of the moving trolley 1; the dust monitoring sensor 7 is located at the top of the support column 4; at least two cantilevers 5 are arranged at intervals along the support column 4; the ends of adjacent cantilevers 5 are perpendicularly connected to the support column 4 along different directions; the outer end of the cantilever 5 is connected to the spraying rack 6; the outer side of the spraying rack 6 is provided with vertically arranged atomizing nozzles 8; the atomizing nozzles 8 are communicated with the water pump 3 through a water supply hose 31; the dust monitoring sensor 7 and the water pump 3 are electrically connected to a dust reduction controller; the dust monitoring sensor 7 is integrated and has functions such as measuring wind direction, wind speed, temperature, humidity, air pressure, etc. The dust monitoring sensor 7 collects and transmits the construction site environment data in real time, and the controller judges whether to start the water pump 3 for dust reduction according to the monitored data.

[0027] After starting the dust reduction, the water pump 3 transports the dust reduction water in the water storage tank 2 to the atomizing nozzles 8, and the water sprays out from the atomizing nozzles 8 to adsorb the dust in the surrounding construction site for dust reduction operations. Since a plurality of cantilevers 5 and spraying racks 6 are correspondingly arranged, therefore, the atomizing nozzles 8 form a plurality of spraying surfaces around the moving trolley 1, effectively expanding the spraying range of the dust reduction water and improving the dust reduction effect.

[0028] As Figure 3As shown, a support sleeve 51 is provided at the end of the cantilever 5, and the support sleeve 51 is rotatably connected to the support column 4; the cantilever 5 drives the spraying frame 6 to swing around the support column 4 for spraying. It can be understood that when the spraying frame 6 is manually controlled to swing, the spraying frame 6 can create an atomized spraying fan surface, further expanding the spraying range of the dust suppression water and improving the dust suppression effect.

[0029] Moreover, a plurality of dust suppression devices are arranged around the local construction area of the construction site. The cantilever 5 is rotated to adjust the orientation of the spraying frame 6 so that the spraying frames 6 of the plurality of dust suppression devices correspondingly form the corners of a frame shape of the construction area, such as a quadrilateral frame, a triangular frame, etc.; arranged in this way, when the spraying frame 6 works, a dust suppression surface for relative spraying can be formed, effectively blocking the dust in the construction area from spreading out.

[0030] Specifically, bearings 53 are installed at the top and bottom of the support sleeve 51. The bearings 53 are sleeved on the support column 4, and the inner ring of the bearing 53 at the bottom is supported on the sliding sleeve 52. The sliding sleeve 52 is connected to the support column 4 by a pin.

[0031] As Figure 5 shown, the device further includes a driving motor 9. The driving motor 9 is fixedly installed on the support column 4, and a gear ring is provided outside the support sleeve 51; the driving end of the driving motor 9 is meshed with the gear ring through a gear 91. Specifically, the driving motor 9 is installed on the sliding sleeve 52 outside the support column 4. The driving motor 9 is electrically connected to the dust controller, replacing manual orientation; the controller controls the rotation orientation of the spraying frame 6 by controlling the driving motor 9 according to the wind direction monitored by the dust monitoring sensor 7, avoiding the atomized water vapor being sprayed towards the windward side and causing waste.

[0032] As Figure 4 shown, the device further includes a shielding member 11; the shielding member 11 includes a fixed plate 111 and a movable plate 112; the two fixed plates 111 are symmetrically arranged on both sides of the support column 4 on the mobile trolley 1; the movable plate 112 is fixedly connected to the cantilever 5, and the movable plate 112 reciprocally swings with the cantilever 5, and the movable plate 112 movably shields the area between the cantilever 5 and the fixed plate 111. When the cantilever 5 is rotated, the provided shielding member 11 effectively blocks the construction site dust from entering the device and causing pollution, eliminating the need for cleaning work.

[0033] Specifically, the fixed plate 111 and the movable plate 112 are concentric arc-shaped baffles that fit together. When the cantilever 5 is rotated, the movable plate 112 can overlap with the fixed plate 111, or the movable plate 112 rotates out to shield the area between the cantilever 5 and the fixed plate 111. The movable plate 112 can be an elastic telescopic plate, which is light in weight and convenient for installation.

[0034] As Figure 4As shown, the device further includes an arc-shaped air guide plate 41; the air guide plate 41 is symmetrically installed on the rotating side of the spraying frame 6; the air guide plate 41 shields the area between the spraying frame 6 and the support column 4.

[0035] It can be understood that two swingable spraying frames 6 are provided on one support column 4. When the support column 4 and the two vertical spraying frames 6 are not coplanar, the air guide plates 41 on the spraying frames 6 form a "V" structure; in a windy construction environment at the construction site, the air guide plates 41 can block the wind from directly blowing the dust in the construction area and reduce the spread of dust. At the same time, the air guide plates 41 make the wind flow towards the spraying frame 6 and the atomizing nozzles 8, and rely on the wind force to make the atomized water move quickly, expanding the dust reduction range of the atomized water.

[0036] As Figure 4 shown, the device further includes an air outlet hood 42; the air outlet hood 42 is connected to the outer side of the air guide plate 41 near the spraying frame 6; the narrow opening of the air outlet hood 42 faces the spraying frame 6, and the wide opening of the air outlet hood 42 faces the support column 4. In this embodiment, the air outlet hood 42 is a "V" - shaped structure; the wind flowing along the air guide plate 41 is collected by the air outlet hood 42, the flow rate increases, and the flow direction is accurate, further improving the spraying range of the dust - reducing water.

[0037] In the description of the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. These are only relational terms for facilitating the description of the present utility model, and the present utility model does not have to be constructed or operated in a specific orientation, nor does it specifically refer to any component or element. It should not be construed as a limitation to the present utility model.

For example, it can be a connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms can be understood according to specific situations.

This specification is described according to the implementation manners.
