The device can be easily moved and fixed where needed by the pulleys 7.
[0026] There are multiple water outlets 6 connected to the side of the main water tank, and a one-way valve is installed in the water outlet 6. The one-way valve directs the one-way flow from the main water tank to the outside. The multiple water outlets 6 are connected to the multiple sub-water tanks in a one-to-one manner with one end away from the main water tank, and a connecting pipe 9 is provided between them.
[0027] Multiple water distribution tanks are interconnected through pipes, and the water level height of each water distribution tank is guaranteed by the principle of communicating vessels.
[0028] A plurality of circulation ports 11 are provided at the bottom of the trough body, and the bottom ends of the plurality of circulation ports 11 are interconnected with the top of the water distribution tank in the trough body where they are located. On rainy days, the water distribution tank can collect rainwater resources through the trough body and the circulation ports 11, which is convenient for dust reduction operations through rainwater and saves water resources.
[0029] The spray cannon 1 has two working modes, namely, a spray mode and a water flow mode, by adjusting the structure of the adjustable nozzle 4. The spray mode is used to spray out dispersed water mist, and the water flow mode is used to spray out a concentrated water column.
[0030] The adjustable water pump 8 has two working modes, namely, a normal mode and a high impact mode, by adjusting its own power. The normal mode is used to spray out a slow water flow, and the high impact mode is used to spray out a high-speed water flow.
[0031] A controller is installed on a mounting base, the controller is electrically connected to an adjusting mechanism, a spray cannon 1 and a plurality of adjustable water pumps 8, and is electrically connected to an ultraviolet receiver 2 and an ultraviolet emitting device 10, the ultraviolet receiver 2 is installed on the outer peripheral side of the mounting base, and the ultraviolet emitting device 10 is installed on the outer side of the tank body, wherein the plurality of ultraviolet emitting devices 10 cooperate with the ultraviolet receiver 2, and the controller receives signals from the ultraviolet emitting device 10 and the ultraviolet receiver 2 to control the working status of the adjusting mechanism, the spray cannon 1 and the plurality of adjustable water pumps 8.
[0032] When the ultraviolet rays emitted by the ultraviolet emitting device 10 hit the dust particles in the air, these particles will scatter the light, and the dust particles will absorb part of the ultraviolet rays. The absorbed light is related to the concentration of the particles. The ultraviolet light intensity change is received and detected by the ultraviolet receiver 2 to determine the dust concentration. By detecting the intensity of the scattered light, the dust concentration in the air can be calculated.
[0033] The controller determines the dust concentration between the two by the intensity of the ultraviolet rays emitted by the ultraviolet emitting device 10 received by the ultraviolet receiver 2, and controls the working state of the regulating mechanism, the spray cannon 1 and the corresponding adjustable water pump 8 when the dust concentration reaches the working threshold.
[0034] When the detected dust concentration reaches the working threshold and there are only one or a few signals, the controller controls the regulating mechanism to make the spray cannon 1 point to the corresponding positions of the adjustable water pumps 8 one by one, and switches the spray cannon 1 to the water flow mode and the adjustable water pump 8 to the high impact mode; when the detected dust concentration reaches the working threshold and there are multiple signals, the controller controls the regulating mechanism to make the spray cannon 1 point to the central position of multiple adjustable water pumps 8, and switches the spray cannon 1 to the spray mode and the adjustable water pump 8 to the high impact mode.
[0035] The output end of the spray gun 1 is provided with a fan blade 5 , and the fan blade 5 is electrically connected to the controller, wherein the controller controls the fan blade 5 to start when the spray gun 1 is switched to the spray mode.
[0036] When the present invention is working, the main structure and the substructure can work independently; When the main structure works independently, the spray cannon 1 works, pumps water from the main water tank, and switches to the spray mode through the adjustable nozzle 4, spraying out fine water mist to cover a large construction area and reduce dust, or switches to the water flow mode through the adjustable nozzle 4, spraying out a strong water flow for local cleaning and dust reduction; When multiple sub-structures work independently, the adjustable water pump 8 works to pump water from the water distribution tank. The adjustable water pump 8 is in normal mode, which is used to spray a slow water flow vertically upward. The fine water vapor formed by the free fall of the water flow accurately covers the local area where the tank is located, thereby achieving more efficient dust reduction. Through the main structure and multiple substructures, the dust reduction range of the construction area is increased, and a more comprehensive dust reduction effect can be achieved; When the controller is working, the intensity of the ultraviolet rays emitted by the ultraviolet emitting device 10 received by the ultraviolet receiver 2 is used to judge the dust concentration between the two. When the dust concentration reaches the working threshold, if the detected dust concentration reaches the working threshold, the signal is single or a few, the control adjustment mechanism is operated to make the spray gun 1 point to the corresponding position of the adjustable water pump 8 one by one, and the spray gun 1 is switched to the water flow mode, and the adjustable water pump 8 is switched to the high impact mode. The spray gun 1 sprays out a converged water column and the adjustable water pump 8 sprays out a high-speed water flow to form a counter-flow water column, and more fine spray is generated through impact to perform local dust reduction, thereby quickly increasing the humidity of the corresponding local area and reducing the flying of dust; When there are multiple signals that the detected dust concentration reaches the working threshold, the control and adjustment mechanism works to make the spray cannon 1 point to the central position of the multiple adjustable water pumps 8, and the spray cannon 1 is switched to the spray mode, and the adjustable water pump 8 is switched to the high impact mode. The spray cannon 1 sprays out dispersed water mist, and the multiple adjustable water pumps 8 spray out high-speed water flow, so that the multiple high-speed water flow and the water mist form mutual impact, further generating fine spray to carry out comprehensive dust reduction, thereby quickly increasing the humidity of the entire area and reducing the flying of dust; The water flow is divided from the main water tank into multiple water distribution tanks through the water outlet 6 and the connecting pipe 9. The main water tank is connected to the external water supply system through the water pipe, thereby ensuring that the spray cannon 1 and the multiple adjustable water pumps 8 can operate continuously and stably; When the spray cannon 1 is in the spray mode, the controller controls the fan blades 5 to rotate, and the rotation of the fan blades 5 helps the spray to spread to a larger area through the action of the airflow, thereby improving the dust reduction effect; When the spray cannon 1 is in the spray mode, the staff can actively control the regulating mechanism to use the spray cannon 1 to wash some construction tools or the ground; When the adjustable water pump 8 is working, part of the ejected water falls back into the tank body and enters the water distribution tank through the circulation port 11 to realize partial water circulation, thus saving water resources; Through the above implementation methods and steps, the dust reduction equipment of the present invention will be able to actively detect the dust concentration and dust distribution area at the construction site, so as to flexibly switch the working modes of the main structure and the sub-structure, and collaboratively complete large-area and local effective dust reduction. Moreover, through the work of the sub-structure, the dust removal action time is increased, thereby improving the safety and cleanliness of the construction environment.
