Description

Technical Field

[0001] The present invention relates to the technical field of river engineering design, and in particular to a closed ship-borne wave energy power generation device and a use method thereof. Background Art

[0002] At present, the main forms of land power generation include thermal power generation, hydropower generation, solar power storage, internal combustion engine power generation, wind power generation and nuclear power generation. These forms have brought electricity to people's lives. However, thermal power generation and internal combustion engine power generation require a large amount of non-renewable resources. Although hydropower and wind power are environmentally friendly, they are limited by rivers, lakes and wind power and cannot completely solve the energy crisis. Since wave energy is a low-density, unstable, pollution-free, renewable, large-reserved, widely distributed and difficult-to-use energy, people have gradually begun to use waves for power generation. However, the use of wave energy is limited to the coast, which is vulnerable to the invasion of marine catastrophic climate, and the development cost is high, the scale is small, the social benefits are good but the economic benefits are poor, and the investment recovery period is long. For a long time, these factors have constrained the large-scale commercial development and development of wave energy.

[0003] The ship wave power generation device is a device that converts the energy of water waves into electrical energy. It is usually composed of a buoy, a float, a crank mechanism, a generator, etc. Its working principle is to use the up and down movement of the wave on the buoy or float to convert the mechanical energy into rotational motion through the crank mechanism, thereby driving the generator to generate electricity. The ship wave power generation device can usually provide independent power supply for lighthouses, buoys, etc.

[0004] Currently, most of the wave energy power generation devices in inland waterways have exposed systems, low space utilization, and are difficult to resist the influence of the external humid environment. Therefore, there is a lack of a ship-borne wave energy power generation device that can achieve the above purpose.

[0043] The present invention adheres to the eco-friendly concept and performs ecological optimization on the device.

[0044] After the float is filled with water and ecological vegetation, the center of mass is located at the central axis of the float and below the water surface.

[0045] The float, small ball joint, crank and the ball joint, the ball gear and the rear re-transmission gear shaft system form a contralateral torque structure. During actual working operation, the torque generated on both sides of the ball joint is equal.

[0046] The central axes of the ball gear and the gear plate are collinear, and the width range of the gear plate is slightly larger than the meshing range distance required for actual work.

[0047] The ratchet is set to move in a clockwise direction and can slide freely in a counterclockwise direction without being subjected to force, that is, there is no resistance during the rising process of the float, and the falling process drives the system to operate normally.

[0048] The inertia steel disc absorbs the inertia moment generated by the unidirectional movement of the ratchet wheel, driving the subsequent power generation equipment to continue working, making the circle radius as large as possible while ensuring the quality and avoiding interference with other moving workpieces.

[0049] The outer shell has a V-shaped opening on the guard plate at the connection with the ball joint to separate the upper and lower guard plates, and a longitudinal threaded steel column is inserted between the separated guard plates to fix them so that the upper triangular guard plate can slide along the steel column. A safety switch is arranged above the steel column to lock the steel column to reduce relative slippage.

[0050] A group of wing plates are arranged outside the shell just in front of the guard plate, and the wing plates are placed on the opposite sides to resist the generated lateral force.

[0051] The transmission belt is intended to be in the form of a V-belt, and other transmission belt types are within the scope of protection of this patent.

[0052] In the power generation and energy storage system, the generator generates electricity by cutting magnetic flux lines in a unidirectional rotation manner, and is driven internally by a rotating disk sandwiched between two magnets.

[0053] The transformer is connected to the output port above the generator and regulates the voltage before inputting it into the battery for unified storage.

[0054] The battery is provided by a plurality of power generation units to form a battery pack, which is connected in parallel to form an integral battery, and is prepared for output through an output port provided at the outermost battery.

[0055] The solid desiccant is arranged in the drying box to ensure the stability of the chemical environment inside the system, which is suitable for the normal operation of other mechanical components. Example 2

[0056] A method for using a closed ship-borne wave energy power generation device comprises the following steps: (1) Install the outer shell near the waterway, pull up the V-shaped shell plate along the screw, insert the ball head of the initial transmission rod system into the ball joint, verify that the connection between the float and the ball joint is normal, then close the outer shell and lock the safety; open the opposite side guard plate, install the spring and push the node system, ensure the collinearity and preload the spring to the working range, and fix the transmission gear shaft system; connect the generator and the energy storage system through the transmission belt and anchor them to the bottom plate of the outer shell, release the preloaded spring to complete the assembly; insert and anchor the drying box pre-loaded with chemical solids, close the outer shell and cover plate, and connect the internal components of the unit; connect the batteries of each power generation unit in parallel, encapsulate and weld the output port, and complete the installation of the entire closed ship-borne wave energy power generation device; (2) The float absorbs waves from ships in the channel and transmits the wave energy to the primary transmission rod system; the primary transmission rod system moves around the ball joint at the contact point with the outer shell and drives the gear at its end to perform related movements; the primary transmission rod system transmits kinetic energy to the secondary transmission gear shaft system through gear meshing; the secondary transmission gear shaft system drives the transmission belt to transmit kinetic energy to the generator and the generator inside the electric energy storage system; the generator regulates the voltage through the transformer and stores the electric energy in the battery.

[0057] This embodiment intends to simulate and implement the actual situation After initially laying out the system housing near the water in the channel, open the top safety device and pull up the "V"-shaped groove at the end of the housing along the two screws, place the ball head of the initial transmission rod system into the ball joint, make sure the float can wait for the ball joint connection to work normally before lowering the "V"-shaped portion of the housing, and close the safety to ensure that the ball joint is successfully stuck so that it can work normally.

[0058] After opening the opposite side guard plate of the housing, insert the spring and push joint system to ensure that the slot axis is in line with the spring center axis. Pre-compress the spring to make it flow out of the working range for subsequent work. After confirming that the spring can work normally, anchor the connecting column of the re-transmission gear shaft system to ensure that the entire gear shaft system can move normally.

[0059] After the generator and the electric energy storage system are connected to the re-transmission gear shaft system through the transmission belt, the generator and the electric energy storage system are anchored on the bottom plate of the housing, and the pre-stressed spring and the push joint system are loosened after the internal system is installed, so that the initial installation is completed; The drying box preloaded with set chemical solids is inserted into the device along the inner notch of the outer wall and anchored. After the above components are anchored, the outer cover is closed and the outer shell notch on the other side is aligned, and the other end of the connecting column is inserted into the notch. At this point, the unit power generation device unit is installed.

[0060] The batteries of multiple power generation device units are connected in parallel, and after confirming that the connection lines are correct, the outermost cover plates of the batteries are sealed and the output ports are welded at the outermost batteries. At this point, a closed ship-borne wave energy power generation device is installed.

[0061] When the ship is traveling by waves, it can be regarded as a water particle making a vertical elliptical periodic motion, driving the float to make the same elliptical periodic motion. Since the bowl-shaped float is connected to the crank, it drives the crank to make an elliptical periodic motion with the same period around the ball joint. The wave energy transmission device in the system is transmitted from the initial transmission rod system to the ball gear at the end thereof and then to the re-transmission gear shaft system. Since the ball gear has lateral movement, the gear plate of the re-transmission gear shaft system needs to be tightly pressed onto the ball gear by the spring and the conveying node system. The gear plate meshes with the ball gear to make reciprocating motion, driving the internal ratchet to produce periodic rotation around the axis, and by driving the inertia disk, the ratchet continues to rotate, thereby driving the outer pulley and belt to move together, and the belt generator generates electricity. The output current is provided to the battery after being regulated by the transformer, and is output outward in an orderly manner through the battery.

[0062] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not restricted by the above embodiments, and the description in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, simple changes and substitutions by those skilled in the art are within the protection scope of the present invention.
