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:
The present invention develops a kind of coastal waters sediment incipient motion device.
Technical background:
Shallow sea silt continues migration under the drive marine effect, cause disasters such as Coastal erosion, harbor district alluvial, main at present by bank protection work control Coastal erosions such as construction dykes and dams, administer harbour, estuary sedimentation with the measures such as becoming silted up, drag silt of dredging, dash, need the cost great cost.
At specified sea areas control sediment incipient motion, and the silt of starting then can be turned bane into boon according to favourable direction migration.It is exactly a kind of application precedent towards technical measures such as silts that the river mouth drags silt, waterpower.But above-mentioned measure needs a large amount of power and mechanized equipment, and can only construct when sea situation is better.
Summary of the invention:
The present invention develops a kind of coastal waters sediment incipient motion device, can be suitable for tidal level automatically and flow to and change, rely on the nature wave flow action to evoke seabed, shallow sea silt fully, and silt is migrated by intended flow direction, no longer need industrial energy such as machine power equipment and electric power, can replace and drag silt and waterpower to dash sediment incipient motion operations such as silt, be used for desilting or protect the beach.The objective of the invention is to develop a kind of sediment incipient motion device of automatic adaptation morning and evening tides.
Technical solution of the present invention: the controlled starting device of self adaptation silt mainly is made up of buoyancy aid, silt excitation screen, screen control reel, damper etc., it is characterized in that buoyancy aid and its underpart silt excitation screen is hinged, silt excitation screen links to each other with screen control reel by control cord, silt excitation screen lower end can hinged rake sledge, is provided with damper between buoyancy aid and its underpart silt excitation plate.Buoyancy aid is formed by box-girder or steel pipe assembly welding, and system is fixed on the seabed with anchor; Silt excitation screen is a fence structure, can also can locally improve overcurrent speed by overcurrent; Screen control reel drives the folding and unfolding of silt excitation screen by the impeller-driven that is used as power with trend with flowing to change.
Buoyancy aid is a device main body, can be package unit buoyancy is provided, and is the main member of accepting Wave energy simultaneously.
Silt excitation screen and subsidiary rake sledge are the effect members that stirs silt, and when screen put down, the energy that buoyancy aid moves under wave action passed to the seabed by screen, stir silt; Trend causes also turbulent in the screen bottom because area of passage reduction causing mud face place flow velocity is accelerated through out-of-date; So unrestrained stream energy all can be utilized effectively.When silt excitation screen was packed up, device significantly weakened seabed silt effect.Screen length is inclined in the seabed greater than the operation area depth of water when putting down, thereby can adapt to the tidal level fluctuation automatically.
Screen control reel is by impeller-driven, and control silt encourages the screen folding and unfolding.Adopt a cover worm-and-wheel gear transmission, impeller and worm screw one, reel links to each other with worm gear, the rotation of trend drives impeller, direction of rotation is subjected to flow to control, thereby makes the folding and unfolding on demand of silt excitation screen.Reel is established tie-down cable, and spacing back impeller stops operating.
Damper plays damping action between buoyancy aid and silt excitation screen, the Wave energy that buoyancy aid is accepted is delivered to the seabed better.
Package unit is with the anchor mooring, and device can be reciprocal within the specific limits with trend, thus the sediment incipient motion in realizing in a big way.
The present invention has following advantage: (1) energy conservation, and with low cost.The present invention utilizes ocean wave mobilization force starting silt fully, does not need industrial energy such as electric power, does not also need complicated power conversion, and the ocean directly utilizes, and is with low cost.(2) unmanned, operation usefulness height, risk are little.Fully automatically, adapt to marine tidal fluctuations during normal operation of the present invention, under severe sea condition, still can bring into play sediment incipient motion usefulness, even efficient is higher.(3) apparatus structure is simple, the reliability height.Device is made of no precision optical machinery and control instrument, low cost of manufacture, reliability height substantially the steel work group welding piece.

The specific embodiment:
Now, the present invention is further described: make buoyancy aid, silt excitation screen, screen control reel and damper etc. and be assembled into one by designing requirement in conjunction with Figure of description; Hinged and the between of buoyancy aid and its underpart silt excitation screen is established damper, and silt excitation screen links to each other by control cord and screen control reel; As required, silt excitation screen lower end can hinged rake sledge.During operation on the sea, buoyancy aid is fixed on the seabed with anchor system, and screen control reel is by the impeller-driven that is used as power with trend.
Wherein: buoyancy aid should be able to provide necessary buoyancy for package unit; Silt excitation screen weight is larger than itself buoyancy, makes it to be easy to folding and unfolding; Screen control reel tie-down cable will be adjusted in advance.
During marine the installation, with towboat the whole series (or whole group) device is dragged to operation sea area (silt excitation this moment screen is in upper) earlier, adjusts length of chain cable then with the auxiliary location of casting anchor of anchor boat, and according to work done in the manner of a certain author industry scope.
Device work automatically after the installation utilizes unrestrained mobilization force starting silt when the trend flow direction meets intended flow direction.If do not need the silt directional migration, then can not establish the screen control device.
