Technical Field

The invention belongs to the technical field of ships, and particularly relates to a power generation device utilizing wave energy of two sides of a ship.

Background

The ship sails in vast sea, the sailing power is mainly provided by a diesel engine, and not only is the electric energy consumed by most large facilities on the ship generated by a generator driven by the diesel engine, but also the ship needs to carry a large amount of fuel, and serious pollution is caused by the combustion and leakage of the fuel. Therefore, the search for new alternative energy sources and energy-saving measures for ships becomes a problem to be solved urgently.

The sea wave energy has the advantages of being high in energy flux density, wide in energy distribution, strong in strength regularity and the like, and is a high-quality renewable resource. At present, various power generation devices using wave energy as an energy source appear, and the power generation devices can be divided into the following devices in principle: the wave energy utilization devices are mostly shore-based devices, and even a small part of the wave energy utilization devices are applied to the sea, the wave energy utilization devices cannot be applied to sailing ships. If the wave energy utilization devices are installed on the ship, additional resistance is added to the navigation of the ship, and the energy consumed by overcoming the resistance cannot be counteracted by the electric energy generated by the devices, so that the energy cannot be compensated. Therefore, if the wave energy can be directly used for sailing ships, fuel oil required by sailing of the ships can be reduced, the wave energy resources around the sailing ships are more abundant, and the wave energy utilization device on the ships has greater practical significance.

For the above reasons, there have been proposed devices for utilizing wave energy on vessels in voyage. The Chinese patent with the patent number of CN 110821742A discloses a merchant ship bow floating body wave energy power generation device and a method. The device's body shape is special, and not only can realize when boats and ships normally navigate, the bow body is gone into water often under the effect of wave, goes out water often, realizes the electricity generation, and the body can play the effect of splitting the wave moreover at boats and ships navigation in-process body, reduces the resistance that boats and ships marchd, has solved the utilization problem of boats and ships in the navigation to wave energy.

However, the devices capable of utilizing wave energy on ships in navigation like the above devices are still very few at present, and the energy-saving effect obtained on the ships based on the devices and the increasing number of the ships have excellent development prospect in utilizing wave energy on the ships in navigation.

When a large commercial ship is sailed, due to the fact that the ship is long, wave energy resources are abundant near two sides of the ship, if the wave energy resources on the two sides can be effectively utilized for power generation, a better power generation effect can be achieved, and if the generated electric energy is used for providing partial power for sailing of the ship, a better energy-saving and emission-reduction effect can be achieved.

The track is fixed on the outer hull of the ship and buckled with the floating block, and the floating block can slide on the outer hull along the track. The connecting surface between two adjacent floating blocks is an inclined surface, the wave-facing surface of the floating block closest to the bow is an inclined surface, and the inclined surface faces to the outboard.

Two ends of the pull rope are respectively connected with two floating blocks which are symmetrical to the centerline plane of the ship. The driving wheels are arranged on a ship deck close to the gunwale and are arranged symmetrically to the ship centerline plane like the floating blocks. The pull rope is connected with the two symmetrical floating blocks through the two driving wheels, and part of the pull rope is coated on the driving wheels. When the floating block moves, the pull rope can drive the driving wheel to rotate. In addition, to avoid taking up deck space, the pull rope is arranged below the deck of the ship through a sleeve. The rotating shaft of the driving wheel is rigidly connected with one end of the transmission shaft, and the other end of the transmission shaft is connected with the generator. The generator is fixed on the generator base, and the generator base is fixed on the deck of the ship.

The length of the stay cord needs to ensure that the lower edge of the corresponding floating block on the other side is just positioned on the ship water line when the floating block on one side is compressed to the limit position of the limit spring.

The limiting base is approximately a cuboid, one side of the limiting base is fixed on the hull outer plate, the upper end face of the limiting base and the upper surface of the ship deck are on the same horizontal plane, and the lower end face of the limiting base is fixed with a limiting spring. Both can guarantee that the kicking block can not dash out the track when boats and ships are sailed in big stormy waves, also can avoid the kicking block distance that rises too big simultaneously, lead to the kicking block of the opposite side of correspondence to be less than the waterline of boats and ships, the kicking block is gone into water and probably can increase the extra resistance of boats and ships.

When the ship port board provided with the device disclosed by the invention swells, the floating block arranged on the ship port board can be subjected to buoyancy or upward impact force of waves, the floating block on the port board can slide upwards along the track under the action of the buoyancy or the impact force, the pull rope cannot bear pressure, the floating block arranged on the ship starboard can slide downwards along the track under the action of self gravity, and at the moment, the movement of the two floating blocks can drive the pull rope fixed on the floating blocks to move, so that the driving wheel is driven to rotate, and the generator is driven to generate electricity through the driving shaft.
