Background
Many rivers in China, especially some rivers in northwest and north China, have very high sand content, and when a reservoir or a barrage is built, the water flow speed is further reduced, so that suspended substances such as silt and the like are deposited on a river bed to form siltation, and a series of adverse effects are generated on the reservoir capacity, the ecological environment, the shipping, the reservoir safety and the like. At present, the way of emptying the storage capacity and reducing the water level of the reservoir in the flood season is mostly adopted, at the moment, the water flow scours the main grooves, and the sedimentation of the reservoir is relieved to a certain extent, but the effect is not obvious. A grit chamber is often required to be arranged at the inlets of water diversion projects and hydropower stations, and the grit chamber needs to be washed out periodically. For a larger-scale desilting basin, a plurality of plane gates or radial gates are often arranged, and the investment is high.

Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and give detailed implementation manners and specific working procedures, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-5, the vertical bidirectional rotary gate water-washed sand system of the present invention generally comprises a sand-washed runner 1, a gate unit and a driving unit.
The sand washing flow passage 1 comprises a bottom surface and two side retaining walls of a concrete structure, and is sequentially divided into an inlet section, a lock chamber section and a sand washing section. Wherein, the barricade of lock chamber section is the concentric arc structure of symmetry setting, receives the restriction of gate scale, and its diameter should be as little as possible under the prerequisite that satisfies the sand washing requirement, consequently, the entrance department is mostly the throat structure with lock chamber section junction, and the sand washing section is the forked tail structure of flaring shape with lock chamber section junction, and has built guide wall 101 usually, divide into a plurality of sand washing grooves 102 with the sand washing section for guide rivers flow in the sand washing groove 102 that corresponds.
The gate unit is located in the chamber section and includes a hinge mechanism 210, a support bracket 220, and a water blocking panel 230. The pivot hinge mechanism 210 is usually one, and only one support frame 220 and one water retaining panel 230 may be mounted thereon, or two sets of support frames 220 and two sets of water retaining panels 230 may be mounted thereon as described in this embodiment. Specifically, the hinge mechanism 210 mainly includes a hinge embedded part 211, a rotating shaft 212 and a connecting part 213, the hinge embedded part 211 is located at the center of the bottom surface of the lock chamber section, the rotating shaft 212 mounted thereon is perpendicular to the bottom surface of the sand washing runner, two connecting parts 213 are mounted on the rotating shaft 212, and each connecting part 213 is connected with a supporting frame 220. The support frames 220 are all steel space grid structures, the length of each support frame is smaller than the radius of the lock chamber section, and the water retaining panel 230 is installed at the other end of each support frame 220. In order to reduce the load of the support frame 220 and enable the support frame 220 to rotate relatively easily, 4-10 supporting wheels 221 are installed at the bottom of the support frame 220, the supporting wheels 221 are arranged close to one side of the water-retaining panel 230, and pre-buried rails 222 are correspondingly installed on the bottom surface of the sand washing flow channel below the supporting wheels 221. Further, a hollow buoyancy tank 223 is mounted on the support frame 220, and the buoyancy tank 223 is also disposed near one side of the water blocking panel 230. The two water retaining panels 230 are arc-shaped panels with equal diameters, and are generally the same in size and shape, and are equidistant from the retaining wall of the chamber section (preferably, the spacing distance is 100 mm). In addition, the bottom of the water retaining panel 230 is provided with an L-shaped water seal 231 made of rubber, and the other end of the L-shaped water seal 231 is attached to the embedded rail 222 to play a role in retaining water.
The driving unit is connected with the gate unit and used for changing the position of the water retaining panel 230 so as to change the position and the opening of the overflowing channel between the gate chamber section and the sand washing section, improve the water flow rate in a mode of narrowing the overflowing section, disturb the sediment deposited at the lower part of the sand washing tank 102 and achieve the purpose of sand washing.
As shown in fig. 1-3, the driving unit may be a hydraulic hoist 301 installed on the outer side of the retaining wall (or on the top of the retaining wall), the hydraulic cylinder of the hydraulic hoist 301 is connected to the frame through a cross hinge, and the piston rod extends into the lock chamber section and is connected to the top of the supporting frame 220. When the hydraulic hoist 301 is operated, the water guard plate 230 may rotate clockwise or counterclockwise about the rotating shaft 212.
As shown in fig. 4 and 5, the driving unit may be a hydraulic motor 302 installed on the top of the retaining wall (or on the top of the retaining wall), and the hydraulic motor 302 is provided with a gear 303 which is engaged with a rack 304 installed on the outer side of the water guard panel 230. When the hydraulic motor 302 is operated, the water guard panel 230 may rotate clockwise or counterclockwise about the rotation shaft 212.
When the vertical bidirectional rotary gate is used for water-bundling and sand-washing, the position and the opening degree between the two water-retaining panels 230 are usually adjusted according to the water flow, namely the position and the size of the overflowing channel are adjusted. Specifically, when the water flow is large, the two water retaining panels 230 are respectively transferred into the retaining walls of the lock chamber sections at the two sides, so that the gate is in a fully open state, and at the moment, the water flow passes through all the sand washing grooves 102 simultaneously; when the water flow is small, the flow passage is required to move in sequence in the clockwise or anticlockwise direction to sand the sand washing grooves 102 in a grading manner, and the size of the flow passage is required to be adjusted to be one, two or three … widths of the sand washing grooves 102 in each sand washing process according to the specific water flow so as to effectively and efficiently finish the sand washing operation.
It should be noted that the main function of the present invention is water flow direction, not water retention, and therefore, complete sealing is not required; secondly, when the water flow is large, even if the gate is fully opened, the overflowing condition may not be met, at this time, the sand washing runner retaining wall and the top of the gate are allowed to overflow, but the pump station part of the hydraulic hoist 301 needs to be arranged at a high position to prevent the hydraulic hoist from being submerged by water.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
