Embodiment Construction

[0015] Now in conjunction with the accompanying drawings of the description, the present invention is further described: according to the design requirements, the floating body, the silt excitation grid, the grid control reel and the damper etc. are assembled and assembled into one; There is a damper between them, and the sediment excitation grid is connected to the grid control drum through the control cable; as required, the lower end of the sediment excitation grid can be hinged to the rake skid. When working at sea, the floating body is fixed on the seabed with anchors, and the grid control reel is driven by the impeller powered by the tidal current.

[0016] Among them: the floating body should be able to provide the necessary buoyancy for the whole set of devices; the weight of the sediment excitation grid plate should be slightly larger than its own buoyancy, so that it is easy to retract; the limit cable of the grid plate control drum should be adjusted in advance.

Abstract

The invention relates to a near sea mud starting device using natural force, which comprises a float, a mud exciting grid plate, a grid plate control drum, a damper. The float is hinged with the mud exciting grid plate locating on the lower part of said float, and the damper is arranged between them. An impeller drives the grid plate control drum to control the retraction and putting-down of mud exciting grid plate through gear worm mechanism. The complete device is fixed by anchor. The present invention arises shallow sea bottom mud by depending completely on natural wave flow, and can be applicable to different tide level and flow direction changes automatically to move mud in definite direction. It is suitable for beach maintenance or dredging.

Description

Technical field: [0001] The invention develops an offshore sediment starting device. technical background: [0002] Shallow sea sediments continue to move under the action of ocean dynamics, causing coastal erosion, siltation in port areas and other disasters. At present, coastal erosion is mainly prevented by building revetment works such as dams, and siltation in ports and estuaries is controlled by measures such as dredging, scouring and silting, and dragging. , requires a huge cost. [0003] Controlling the start-up of sediment in a specific sea area and making the start-up sediment move in a favorable direction can turn harm into benefit. The technical measures such as estuary dragging and silting and hydraulic scouring and silting are a kind of application precedent. However, the above measures require a large amount of power and mechanical equipment, and can only be constructed when the sea conditions are good. Invention content: [0004] The invention develops a...
