Description

TECHNICAL FIELD

[0001] The application relates to a rotary screen, in particular to a water power transmission screen. BACKGROUND

[0002] When filtering water, a screen is usually used to screen out impurities in the water flow, so as to ensure that no other impurities are mixed in the water during use. When screening out impurities in the water, a plurality of filter screens are usually arranged, so that the water flows from one end of the filter screen to the other end of the filter screen. This screening method is prone to cause the filter screen to be blocked. Another method is to use a rotary screen to screen the water flow. However, the existing rotary screen is usually driven by a motor, and long-term use can cause water pollution and energy waste. CONTENT OF THE INVENTION
