Description

Technical Field

[0002] Irrigation district is a term commonly used in water conservancy, agriculture, and industry. It refers to farmland areas covered by water source projects (such as reservoirs, rivers, and wells) and irrigation systems (channels and pipelines), and agricultural planting areas that can be artificially irrigated. Core components: Water sources: reservoirs, rivers, groundwater, etc. Water supply systems: channels or pipelines at various levels, such as main canals, branch canals, and ditches. Drainage systems: drainage ditches to prevent soil salinization. Farmland: land where crops such as rice and wheat are grown. When an irrigation district is operating normally, it is necessary to monitor the water flow in the irrigation district to determine whether the water supply has reached the designed value. Turbine flow meters are generally used to monitor the water supply.

The cutting motor 53 drives the cutting blade 52 to rotate. The cutting blade 52 rotates to cut the waterweed wrapped around the turbine blades 13 and drops it into the inspection box 2, thereby completing the cutting of the waterweed; then the first motor 56 is started, and the first motor 56 drives the transmission wheel 58 to rotate.

Under the action of centrifugal force, the waterweed is thrown off the turbine blades 13, thereby improving the waterweed clearing effect; The water is then delivered to the inspection box 2 through the water pipe 17 by the delivery pump 16 and impacts the turbine blades 13, causing the waterweed attached to the turbine blades 13 to fall off, further improving the waterweed removal effect; Finally, the opening and closing plate is driven to rotate by the opening and closing motor, and the opening and closing plate rotates to open the discharge gap, and the aquatic plants in the inspection box 2 are removed.
