Description

Wave power generation device that can navigate

Technical Field

The utility model relates to a wave energy conversion technology field, in particular to wave power generation facility that can navigate.

Background

Wave energy resources are abundant in reserves and have great development and utilization potentials. However, the development and utilization of ocean wave energy are expensive due to the fact that wave energy is extremely unstable, far away from continents, severe ocean environment, seawater corrosion, marine organism adhesion and the like. These costs are mainly reflected in the material costs of the plant, the construction costs, the conversion mechanism costs, the release, transport and recovery costs, the anchoring costs, the maintenance costs and the environmental costs, etc. At present, wave energy utilization technologies are various, floating wave energy utilization technologies are the mainstream of research due to wide application range, and the mainstream floating technologies mainly comprise three major technologies, namely oscillating water column technology, wave-crossing technology and oscillating floater technology.

The floating oscillating floater technology is characterized in that waves are used for pushing one floating body to translate or rotate relative to another floating body (a supporting platform) to convert the wave energy into mechanical energy of floating body movement, a device developed based on the technology must be a double (multiple) floating body and is submerged or semi-submerged in seawater, the characteristic means that the material utilization rate is low (the double or multiple floating bodies are relatively large), collision accidents are easy to happen between the floating bodies, a hinged part is easy to damage due to large acting force, the single machine installation capacity is limited, and the direct towing resistance is large.

The floating wave-crossing technology is characterized in that a single floating body (bearing platform) is used, and the device is required to bear the weight of a conversion carrier (seawater), so that the mooring system is large in structural scale and high in strength requirement, and under the combined action of wind, waves and currents, a water turbine is in contact with the seawater, is greatly influenced by attachment of marine organisms, and has large direct towing resistance.

The floating oscillating water column technology is characterized in that a single floating body is adopted, the material utilization rate is high, the problem of collision between the floating body and the floating body does not exist, an air turbine and a generator are positioned on the water surface and are not influenced by seawater and marine organisms, and the maintenance is convenient. The best known form of floating oscillating water column technology is the back bend technology, which mainly consists of an L-shaped pipeline, an air chamber, a buoyancy chamber, an air turbine and a generator. The technical conversion principle of the backward bent pipe is that wave energy is converted into mechanical energy and mechanical energy of floating body movement and fluid movement in a cavity, the mechanical energy is converted into pneumatic energy, and the pneumatic energy is converted into electric energy through an air turbine and a generator, and the electric energy is generally divided into 2-stage conversion: primary conversion and secondary conversion. The primary conversion is the conversion of wave energy to aerodynamic energy (evaluated by capture width ratio) and the secondary conversion is the conversion of aerodynamic energy to electrical energy. Under the condition of the wide pool loose mooring regular wave, the capture width ratio measurement value reaches 204.5% at most, and under the condition of the random wave, the capture width ratio measurement value reaches 87.2% at most. The latest test of a novel small prototype water tank of the back bend pipe by a third party (national oceanographic technology center) shows that: the highest conversion efficiency of waves to electricity under the load of the regular wave battery reaches 35.65 percent, the highest average efficiency of waves to electricity under the load of the random wave battery reaches 26.66 percent, and the high conversion efficiency is achieved. The back bend technique exhibits high energy conversion characteristics. Compared with other wave energy utilization devices, the rear pipe bending device has shallow draft, is convenient to transport and launch, and does not need floating state adjustment, so that the site construction becomes simple. However, although the draft of the rear bent pipe device is relatively shallow, simple and high in conversion efficiency, the towing ship is required for marine construction, the towing resistance is large during towing, and the stability of the device is poor, and the single machine installed capacity is limited.

At present, both the floating and floating oscillating water column technology and the floating and wave-crossing technology have the characteristics of high manufacturing cost and high ocean engineering cost, the floating oscillating water column technology has the advantages of simple structure, low manufacturing cost and high conversion efficiency, but the towing ocean engineering cost is high, the stability of the device is poor, the single machine installed capacity is limited, and the technology of generating electricity by using waves cannot be popularized.
