Detailed Description
As shown in fig. 1, the spray dust-settling system for the construction of the pumped storage power station comprises a water storage tank 1, a water storage tank water supply pump 3, a water level controller 4, a water storage tank water supply pipeline 5, a water supply pipeline 6, a spray control electromagnetic valve 7, a spray water supply pump 8, an end plug 9, a tee joint 10, a spray gun 11, a spray automatic controller, the water storage tank 1 is connected with a water source 2 through the water storage tank water supply pipeline 5, the water storage tank water supply pump 3 is connected with the water storage tank water supply pipeline 5, and the water storage tank water supply pump 3 can input required water from the water source 2 to the water storage tank 1. The water level controller 4 is arranged in the water storage tank 1, and the water level controller 4 is electrically connected with the automatic spraying controller. The water supply pipeline 6 is connected with the bottom of retaining jar 1, and end shutoff 9 and the end connection of water supply pipeline 6 spray control solenoid valve 7 and are connected with water supply pipeline 6, spray control solenoid valve 7 and are close to the delivery port of retaining jar 1, spray the working shaft 8 and are connected with water supply pipeline 6, are connected with a plurality of tee bend 10 on the water supply pipeline 6, and tee bend 10 is connected with watering spray gun 11. The automatic spraying controller is used for controlling the whole system to work, and the water storage tank water supply pump 3, the spraying control electromagnetic valve 7 and the spraying water supply pump 8 are respectively and electrically connected with the automatic spraying controller.
The pipe material of the water supply pipeline 6 is a fabric rubber hose with the specification of phi 50 and the working pressure of 1.0 MPA. As the temporary roads on the construction site are all earth and stone pavements and are not paved by concrete, the running vehicles are easy to roll the pipelines, and the soft rubber pipes are adopted, and the pipelines are easy to damage if steel pipes or PPR pipes are adopted.
The water storage tank 1 adopts 10m3The plastic cylindrical water storage tank. Considering that the temporary road position of a construction site mostly has no fixed water source,and considering the construction cost, a water storage tank is adopted for storing water, and a spraying control electromagnetic valve 7 is arranged at the water outlet of the water storage tank to control the water outlet. A water level controller 4 is installed in the water storage tank, and when the water level in the water storage tank is insufficient, a water supply pump 3 of the water storage tank automatically opens a water supply source.
The spray water supply pump 8 adopts a 4.0kw booster pump, the water inlet end of the pump is connected with the inlet at the bottom of the water storage tank, and the outlet is connected with the spray system.
The sprinkling spray gun 11 adopts a zinc alloy controllable rocker arm spray head, the size is DN25, the spraying pressure is 2.5-4 kg, the connection mode is external thread connection, and the spraying spray gun adopts threads to be connected with a round galvanized steel pipe with the same diameter DN25 and the length of 1.0 meter. The spray gun is not suitable for spraying, and the water outlet of the spray gun is too thin, so that blockage is easy to occur.
As shown in FIG. 2, each construction temporary road 12 is generally 5-7 m wide, so when the spraying system is installed, the distance between two adjacent spraying guns 11 is controlled to be 14m, and the distance between the spraying heads of the spraying guns is controlled to be 7 m. A plurality of water spraying spray guns are arranged on one side of a temporary construction road 12, a square concrete pier 14 with the length, width and height of 20cm is poured at the bottom of each water spraying spray gun 11 for fixing, and black and yellow reflective paint is coated on the square concrete pier to achieve the warning effect. And covering the water supply pipeline 6 by soft soil after the laying is finished to form a soil ridge with the thickness of about 15cm, thereby playing a role in protection.
Control modules such as the automatic spraying controller are installed in the control box, and the control box is installed on the concrete base to prevent rainwater influence.
The water storage tank 1 is arranged on the outer side of a construction road, the vehicle passing cannot be influenced, meanwhile, the water storage tank is arranged at a position close to a water source point, a water level controller arranged in the water storage tank controls the starting of a water supply pump of the water storage tank, and when the water level in the water tank is insufficient, a switch is automatically switched on to supplement the water source. When the spraying system is far away from the water source point, a well can be drilled to fetch water or a watering cart is adopted to store water regularly. In the area (such as the opening of a traffic tunnel) near the sewage treatment station, the treated water can be directly used as a spraying water source.
The rotation angle of the sprinkling spray gun is controlled to be 180 degrees, and the influence of the terrain is eliminated in order to control the water outlet distance of 7m according to the power of the water supply pump of the set of sprinkling system. When the whole set of system has 11 spray guns, the length of a water supply pipeline between every two spray guns is 14 meters, and the total length of the pipeline is about 145 meters (the length of the water pipe between the outlet of the water containing pump and the first spray gun is about 5 meters).
The pumped storage power station has multiple construction points, the main construction working surfaces comprise upper and lower reservoirs, underground plants, water delivery and power generation systems, upper and lower reservoir dams and the like, and the dust is easily raised because slag transport vehicles pass through. Therefore, the installation place of the spraying system is preferably selected from a traffic tunnel portal (the slag car frequently enters and exits an underground workshop), a main hardened pavement with large traffic flow and one side of each temporary construction road.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, which may be modified and varied by those skilled in the art.
