Abstract

The invention discloses a water retaining structure for a trash rack. The water retaining structure comprises the trash rack, wherein a first mounting part is arranged at the top of the upstream faceof the trash rack, and a second mounting part and a third mounting part are sequentially arranged below the first mounting part; a first winding mechanism comprises a first winding drum arranged on the first mounting part, a steel wire rope is arranged on the first winding drum, one end of the steel wire rope is connected with the first winding drum, and the other end of the steel wire rope is connected with the third mounting part; and a second winding mechanism is located between the steel wire rope and the trash rack and comprises a second winding drum and a rubber winding plate in frictionconnection with the steel wire rope, one end of the rubber winding plate is connected to the second winding drum in a wound mode, and the other end of the rubber winding plate is connected with the second mounting part through a connecting piece. Meanwhile, the invention discloses a using method of the water retaining structure. When the steel wire rope is unwound through the first winding drum,the rubber winding plate is unfolded under the action of gravity and attached to the upstream face of the trash rack to achieve the water retaining function; and when the steel wire rope is wound through the first winding drum, the rubber winding plate winds upwards around the second winding drum through friction force with the steel wire rope to achieve the trash holding purpose.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering gates, in particular to a water retaining structure for a trash rack and an opening and closing method thereof. Background technique [0002] Trash racks are widely used in water conservancy and hydropower projects to block debris that may enter the flow channel, such as branches, miscellaneous trees, aquatic plants and ice floes, to purify water bodies and protect flow channels, gates, turbines and other equipment. For small-scale water diversion projects, gates are often not provided behind the trash rack, and maintenance gates are often not provided before the working gate behind the trash rack. Therefore, when equipment such as channels or working gates needs to be overhauled, the only way to do so is to pile up soil to form a temporary cofferdam, or close the upstream gate to cut off the water flow. When the earth-pillar cofferdam is used, the constructio...
