Abstract
The utility model provides a general novel structure which can convert wave energy of wave surfaces to electric energy efficiently and is called as a nodding duck-type wave energy conversion device. The technical solution is characterized in that the X and Y directions of the nodding duck-type device are restrained and the Z direction of the nodding duck-type device is free; four corners of the nodding duck-type device can vertically slide on guide pipes set up on a foundation; and the top head ends of the guide pipes are connected with a circle of connection rods. On the premise that a duck body is not modified, a plate-shaped pedestal of an underwater appendage thereof is modified to be a mat-type pedestal which is provided with water injection/drainage pipe valves and intake/exhaust valves, so that the nodding duck-type device can be located at the ideal wave surface height through water injection/drainage adjustment and the duck body can sink through water injection before severe typhoon assault and thus can be protected from the severe typhoon assault. Anti-falling safety ropes are also arranged for safety. The nodding duck-type device can really play its part.
Description
Technical field
The utility model relates to a kind of general, and the wave energy of wavy surface is converted to electric energy expeditiously, is called the new structure of the duck Wave energy converting device of nodding (lower to the duck device of nodding), belongs to ocean engineering and wave-activated power generation field.
Background technique
Engineer who is Salter has introduced a kind of wave energy conversion method of uniqueness in his paper in 1974, make the sinusoidal wave conversion efficiency of two dimension can be near about 90%, and is such as Fig. 1, shown in Figure 2.Because the shape of this device and the motion that roadability exactly likes duck, thereby be called the duck that nods.The motion of incoming wave makes kinetic pressure can effectively promote the duck body to rotate around axis.In addition, except kinetic pressure, the change of hydrostatic pressure also makes near the buoyancy aid of duckbilled and partly does rising and sinking to-and-fro motion.Because the motion that produces of these two kinds of pressure is synchronous, in the one-period of wave motion, will move energy and potential energy of the duck that nods transforms away by hydraulic pressure installation simultaneously and then by hydraulic pressure or electric power system kinetic energy is converted to electric energy.But the duck device performance of nodding under irregular wave action studies show that under irregular wave action, system effectiveness is much lower.Under abominable ocean environment, device also very easily damages, and duck is not extensively promoted so Salter nods.Therefore, for the duck device of nodding can be brought into play usefulness and must accomplish:
1. device must in certain depth of water scope, namely be in the regular wave scope;
2. the method for evading calamitous sea situation (such as typhoon) must be arranged;
3, must have round-the-clock corrugated can utilize ability, be fixed on as shown in Figure 1 the sea bed situation, then when low water mark the duck body surface profit do not use the corrugated can, and the duck body is submerged under the corrugated when high water mark, knows that from Wave Theory its suffered wave force has reduced.Know that from ocean knowledge tidal level not only has astronomical tide (moon cycle causes) to also have landscape tide (strong wind causes), it is worthless that the duck device of therefore will nodding is anchored at sea bed.
Abroad have at present the duck wave energy conversion loading amount of nodding is placed the rule ripple zone of certain depth of water with cable at the tight way of seabed anchorage posttension (seeing Fig. 3) the duck device of will nodding, but as aforementioned it still have the position influence that not only makes moist, and the shortcoming of anti-unrestrained ability a little less than also.In addition, cable anchorage in seabed also is difficult, all to employ expensive floating pile driver, floating type mooring such as Fig. 4 of being created by the Chinese science and technology personnel show, be characterized in a, the b. duck body that casts anchor in the seabed is floating, its advantage is the position influence and can resist 14 grades of typhoons of not making moist, but see from the more professional angle of ocean engineering and the scheme of Fig. 4 to still have following point;
1, the anti-drift problem of fixed point; Be difficult to guarantee that with the mooring of mooring formula way anchorage it " does not drag of anchor ", once " dragging of anchor " just produces drift.Therefore, for " fixed point " and reliable mooring, anchor chain is not to adopt this " pressure " formula in the ocean engineering, but stretched wire anchor form, it has been widely used in single point mooring and " semi-submersible type " drill ship technology, but this stretched wire anchor form must have the enough depth of water to cause " stretched wire shape " and stretched wire anchor very long, and cost is high high;
2. see from Fig. 4 to allow the duck device of nodding sink to making the avoiding action operability indefinite, from the precedent that ocean engineering does not adopt the sinking mode to evade through examining " single point mooring " etc. yet, reason also is not Strong of operability;
3. the setting of submarine anchoring point, with stake, then because employ ocean engineering ship, its expense is just very high if prevent from dragging of anchor.In offshore oil engineering, marine installation exercise expense accounts for the 30%-40% of whole engineering cost sometimes.
Therefore, it is urgent solving the nod anchoring of duck device and mooring, significant problem.

Summary of the invention
Analyzed the nod anchoring of duck device and mooring present situation, the utility model proposes and a kind ofly help mooring the scheme heavy and underwater cup-shaped foundation that consolidated subsoil arranges based on CN 201962696U is disclosed with sluicing, the main points of this technological scheme are:
1. based on the canard Wave energy converting device of nodding of novel mooring, it is characterized in that the device mooring adopts X, the Y-direction constraint, Z direction free way, concrete way is that nod four jiaos in duck device can be slided up and down on the conduit that erects on the basis.
2. it is to form with basic built-in pipe socket that four jiaos in the duck device of nodding can slide up and down the conduit that erects on the basis.
3. the duck underwater appendage of nodding is to be connected with the sliding sleeve connecting plate that is inserted in conduit by settling type base connecting plate.
4. the duck body is not changed under the prerequisite; change the tabular pedestal of its underwater appendage into settling type; it is the closed box shape; and water filling/draining pipe valve and import/exhaust pipe valve be installed; regulate by notes/draining; allow the duck device of nodding be in optimal wave surface height, before the Strong typhoon, the water filling protection Duck body that sinks then.
5. the settling type base end face is welded with suspension ring, and corresponding basic end face gives and is embedded with hanger.
6. the underwater cup-shaped foundation of basis for help base heavy and that reinforce to arrange with sluicing, or other form basis, such as gravity type, caisson type, pile foundation type etc., basic material Mining reinforced concrete, or steel or composite material.
Superiority of the present utility model is: the nod anchoring of duck device and mooring are stressed clear and definite, clear, safe and reliable, operability Strong, cost is low, be the successful case of using basis and a mooring difficult problem in the solution wave energy power generation of ocean engineering technology, make the duck device of nodding of this neotectonics can really bring into play benefit.
