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 method for using the same. Background Art

[0002] Currently, the main forms of land-based power generation include thermal power, hydropower, solar power storage, internal combustion engines, wind power, and nuclear power. These sources provide electricity to people. However, thermal and internal combustion engines require significant amounts of non-renewable resources. While hydropower and wind power are environmentally friendly, they are limited by rivers, lakes, and wind power, and thus cannot fully address the energy crisis. Wave energy is a low-density, unstable, pollution-free, renewable, abundant, widely distributed, and difficult to utilize energy, leading to its increasing use in the field. However, wave energy utilization is limited to coastal areas, making it vulnerable to adverse marine climate events. Furthermore, development costs are high, the scale is small, and while social benefits are good, the economic benefits are poor, with a long payback period. These factors have long hindered the large-scale commercial development and utilization of wave energy.

[0003] A ship-borne wave generator converts surface wave energy into electrical energy. It typically consists of a buoy, a float, a crank mechanism, and a generator. Its operating principle is to utilize the up-and-down motion of the buoy or float caused by waves, converting the mechanical energy into rotational motion through the crank mechanism, which in turn drives the generator to generate electricity. Ship-borne wave generators can typically provide independent power supply for lighthouses, buoys, and other objects.

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

[0005] Existing patents, such as CN 107559134 B, disclose a ship-borne wave energy generator. This device uses floating blades connected to a movable rod system. The simple harmonic motion of the waves drives the blades to flip, generating electricity through an oscillating air column. However, this structure is open and complex, occupies a large space, suffers from high mechanical losses, and is difficult to withstand in the humid environment of the system's operating area.

[0006] Traditional wave power generation systems struggle to cope with humid coastal and waterway environments. Exposure to high humidity can easily lead to corrosion and damage to the mechanical structure, negatively impacting the ecological environment in which the system is located.

[0044] Furthermore, the enclosed ship-borne wave energy power generation device further comprises: a drying box, which is placed inside the outer shell and close to the seam of the shell wall.

[0045] The float touches the water surface and is connected to the primary transmission system via a ball joint at its top. The primary transmission system contacts the outer shell through a ball joint in the middle and is connected to a ball joint at the end. The ball joint is connected to the secondary transmission gear shaft through gear meshing.

[0046] The invention adheres to the concept of ecological friendliness, and the device is treated with ecological optimization, and the detailed treatment method is as follows: the float and the primary transmission rod system are made of environment-friendly materials, and the shape is imitated from the stems of aquatic plants; aquatic plants are planted in the float; the crank in the primary transmission rod system is imitated from a wooden pile structure to reduce visual damage; the exposed part of the shell is engraved with a grid, and humus soil is covered and common revetment vegetation is planted.

[0047] 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.

[0048] The float, the ball joint, the crank, the ball gear, and the rear transmission gear shaft system form a force moment structure, and the force moments on both sides of the ball joint are equal during actual operation.

[0049] The central axes of the ball gear and the gear disc are collinear, and the width of the gear disc is slightly larger than the meshing range distance required for actual work.

[0050] The ratchet is set to move in the clockwise direction, and the counterclockwise direction is free to slide under the force, that is, there is no resistance during the upward movement of the float, and the system operates normally during the downward movement.

[0051] The inertia steel disc absorbs the inertia moment generated by the one-way movement of the ratchet, and drives the subsequent power generation equipment to continuously work, while ensuring the quality, making the circular radius as large as possible, and avoiding interference with other moving workpieces.

[0052] The shell, the upper and lower protective plates separated by the "V" shaped opening at the connection of the ball joint, the longitudinal threaded steel column inserted between the two separated protective plates for fixation, the upper triangular protective plate that can slide along the steel column, and the safety switch above the steel column to lock the steel column and reduce relative sliding.

[0054] The transmission belt adopts a triangular transmission belt form, and the remaining transmission belt forms are within the protection scope of the patent.

[0055] The power generation and energy storage system uses a one-way rotating cutting magnetic induction line form to generate electricity, and uses a two-magnet inner clamping rotating disc form for driving inside, and it needs to be declared that the remaining power generation equipment is within the protection scope of the invention.

[0056] The transformer is connected to the output port above the generator and inputs the regular voltage to the storage battery for unified storage.

[0057] The battery is provided by multiple groups of power generation units to form a battery pack, which is connected in parallel to form an integral battery, and output is prepared through the output port provided at the outermost battery.

[0058] The solid desiccant is arranged in the drying box to ensure that the chemical environment inside the system is stable and suitable for the normal operation of other mechanical components. Example 2

[0059] A method for using a closed ship-borne wave energy power generation device comprises the following steps:

[0060] (1) Install the shell at the waterfront of the channel, pull 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 shell and lock the safety; open the opposite side guard plate, install the spring and push the joint system, ensure the collinearity and pre-load 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 shell, release the pre-loaded spring to complete the assembly; insert and anchor the drying box pre-loaded with chemical solids, close the 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 enclosed ship-borne wave energy power generation device;

[0061] (2) The float absorbs the waves from the 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 the kinetic energy to the secondary transmission gear shaft system through gear meshing; the secondary transmission gear shaft system drives the transmission belt to transmit the kinetic energy to the generator and the generator inside the power storage system; the generator regulates the voltage through the transformer and stores the electrical energy in the battery.

[0062] This embodiment intends to conduct simulation implementation based on the actual situation

[0063] After initially laying out the system casing near the waterway, open the top safety device and pull up the "V"-shaped groove at the end of the casing along the two screws, place the ball head of the primary transmission rod system into the ball joint, ensure that the float can wait for the ball joint connection to work normally, then lower the "V"-shaped part of the casing, and close the safety to ensure that the ball joint is successfully locked so that it can work normally.

[0064] After opening the opposite side guard of the housing, insert the spring and push joint, ensuring that the slot axis is aligned with the spring center axis. Pre-compress the spring so that it flows out of the working range for subsequent work. After confirming that the spring can work normally, anchor the connecting column of the retransmission gear shaft system to ensure that the entire gear shaft system can move normally.

[0065] After the generator and the electric energy storage system and the retransmission gear shaft system are connected by the transmission belt, the generator and the electric energy storage system are anchored on the bottom plate of the shell, and the pre-pressed spring and the pushing joint system are loosened after the internal system is installed, so that the preliminary installation is completed;

[0066] The dry box preloaded with the set chemical solid is extended into the inside of the device along the inner notch of the outer wall and is anchored, and after it is confirmed that the above-mentioned components are all anchored, the outer cover plate is closed and the other side of the shell notch is closed, and the other end of the connecting column is deeply inserted into the inside of the notch. At this time, the unit installation of the unit power generation device is completed.

[0067] The batteries of a plurality of power generation device units are connected in parallel, and after it is confirmed that the connection line is correct, the outermost cover plate of the battery is packaged, and the output port is welded at the outermost battery. At this time, the installation of a kind of closed ship wave energy power generation device is completed.

[0068] When the ship wave arrives, it can be considered that the water quality point does vertical elliptical cycle movement, driving the float to do the same elliptical cycle movement, and since the bowl-shaped float is connected with the crank, it drives the crank to do the same elliptical cycle movement around the spherical hinge. The wave energy transmission device in the system is transmitted by the initial transmission rod system to the spherical gear at the end of the transmission rod system, and then transmitted to the retransmission gear shaft system. Since the spherical gear has transverse movement, the gear disc of the retransmission gear shaft system needs to be tightly pressed onto the spherical gear by the spring and the conveying joint system. The gear disc engages the spherical gear to reciprocate, driving the internal ratchet to rotate periodically around the shaft, and through the inertia disc, the ratchet continues to rotate, thereby driving the outer pulley and the belt to move together. The belt generator generates electricity, and the output current is regulated by the transformer and provided to the battery, and then sequentially output to the outside through the battery.

[0069] The above shows and describes the basic principles, main features and advantages of the present application, and those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application, and simple changes and substitutions by those skilled in the art without departing from the spirit and scope of the present application are within the protection scope of the present application.
