Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, and particularly relates to an automatic control system for foundation pit dust reduction in a smart construction site. Background Art

[0002] During the construction process of municipal engineering, a large amount of dust will be generated. These dusts will seriously affect the surrounding environment and air quality, and will also cause certain harm to the physical health of on-site workers. Therefore, in order to reduce the impact of dust on the surrounding environment and human health, at present, during the engineering construction process, a foundation pit dust reduction device is mostly used to achieve dust reduction at the construction site.

[0003] However, most of the common existing foundation pit dust reduction devices adopt sky curtain dust prevention: the effect of spray dust reduction is achieved by installing spray pipes on the sky curtain. However, most of the existing spray pipes are fixed, the range of spray dust reduction is limited, and the water mist formed during the spraying process is easily affected by the natural wind and drifts everywhere, which has an adverse effect on the effect of spray dust reduction; and after the foundation pit project is completed, it also needs to be demolished, which is a waste of time and cost. Summary of the Invention

[0016] The features and other related features of the utility model are further described in detail below through embodiments with reference to the drawings for the understanding of those skilled in the same industry:

[0017] As Figures 1-4 , the marks in the figure are respectively: self-propelled dust reduction trolley 1, mobile vehicle body 11, water storage tank 12, rotatable base 13, water pump 14, horizontal telescopic bracket 15, water delivery pipeline 16, winch mechanism 17, guide pipe 18, fixed pulley 19, foundation pit 2, spray plate 3, atomizing nozzle 31, stay rope 32.

[0018] Embodiment: As Figures 1-4As shown in the figure, this embodiment specifically relates to an automatic control system for foundation pit dust reduction in a smart construction site. The automatic control system for foundation pit dust reduction includes a dust concentration sensor and a self-propelled dust reduction vehicle 1. The dust concentration sensor is arranged in the foundation pit 2 to detect the dust particle concentration in the foundation pit 2, and wirelessly transmit the detected data to the self-propelled dust reduction vehicle 1, controlling the self-propelled dust reduction vehicle 1 to travel along the planned route and spray synchronously to achieve the purpose of dust reduction.

[0019] As Figure 1 shown, the number of dust concentration sensors is several, and they are arranged on the lateral supports and side support structures of the foundation pit 2 (not shown in the figure and omitted), ensuring that the monitoring range can cover all corners of the foundation pit 2.

[0020] As Figures 1-4 shown, the self-propelled dust reduction vehicle 1 includes a mobile vehicle body 11, a water storage tank 12, a rotatable base 13, a water pump 14, a horizontal telescopic bracket 15, a water pipeline 16, a winch mechanism 17, a guide pipe 18, and a fixed pulley 19. The mobile vehicle body 11 has a platform for installing various devices. The rear end of the horizontal telescopic bracket 15 is installed on the platform of the mobile vehicle body 11 through the rotatable base 13. Under the guidance of the rotatable base 13, the horizontal telescopic bracket 15 can rotate within a certain angle range to meet the requirements of work and storage. The water storage tank 12 and the water pump 14 are installed on the platform of the mobile vehicle body 11, and the water pump 14 is connected to the water storage tank 12 and can perform pumping operations. The winch mechanism 17 is installed at the front end of the horizontal telescopic bracket 15, and the water pipeline 16 is wound on the winch mechanism 17. One end of the water pipeline 16 is connected to the water pump 14, and the other end of the water pipeline 16 is connected to the spray plate 3 through the guidance of the fixed pulley 19. The water pump 14 can pump water from the water storage tank 12 and pump the water to the spray plate 3 through the water pipeline 16 to spray outwards for dust reduction.

[0021] As Figures 1-4 shown, in this embodiment, the horizontal telescopic bracket 15 specifically adopts the form of a hydraulic telescopic rod. A vertical guide pipe 18 is fixedly arranged at the front end of the horizontal telescopic bracket 15. The guide pipe 18 has a certain height and allows the water pipeline 16 to pass through. A fixed pulley 19 is arranged at the top port of the guide pipe 18. The fixed pulley 19 can guide the water pipeline 16 extending from the winch mechanism 17, so that the water pipeline 16 extends into the guide pipe 18 and passes through. While the water pipeline 16 is fixedly connected to the top of the spray plate 3, in order to ensure the stability of the spray plate 3, a stay rope 32 is also arranged between the water pipeline 16 and the spray plate 3. It should be noted that the water pipeline 16 has sufficient tensile strength to ensure that it can bear the gravity of the spray plate 3.

[0022] As Figures 1-4As shown in the figure, a number of atomizing nozzles 31 are evenly distributed on both side surfaces of the spray plate 3, and each atomizing nozzle 31 is distributed in a rectangular array. The water delivery pipeline 16 is connected to the upper end of the spray plate 3, and the water delivery pipeline 16 branches into a number of water delivery branch pipes in the inner cavity of the spray plate 3, and each water delivery branch pipe is connected to a column of atomizing nozzles.

[0023] As Figures 1-4 shown in the figure, a control host (not shown in the figure) is further provided on the mobile vehicle body 11, and the dust concentration sensor is wirelessly connected to the control host. During the working process, the control host on the mobile vehicle body 11 plans the moving path of the mobile vehicle body 11 and the height range where the spray plate 3 is located according to the received dust concentration spatial distribution data, so as to achieve the purpose of efficient and accurate spray dust reduction. It should be noted that in addition to moving along the ground around the foundation pit 2, the mobile vehicle body 11 can also move along each transverse support of the foundation pit 2, so as to cover the entire planar space of the foundation pit 2, and the spray plate 3 is lifted and lowered in the vertical direction by controlling the forward and reverse rotation of the winch mechanism 17.

[0024] The beneficial effects of this embodiment are as follows: high degree of automation, perceiving the dust distribution in the foundation pit through the sensing data based on the dust concentration, and performing automatic spray dust reduction through the self-propelled dust reduction trolley, which can achieve dust reduction treatment for the depth and different horizontal directions of the foundation pit.
