Description

Technical Field

[0001] The invention belongs to the technical field of power generation devices, and in particular relates to a fully enclosed wave power generation mechanism. Background Art

[0002] As we all know, our country has vast sea areas that store unlimited ocean energy. Wave energy, as one of the ocean energies, has the characteristics of high energy density and renewability, and has very good application prospects.

[0003] The ocean contains a large amount of energy, including wave energy, tidal energy, ocean temperature difference energy, salt gradient energy, ocean current energy, etc. Tidal energy and ocean current energy have high energy density, but are too limited by time and resistance; the quality of ocean temperature difference energy and salt gradient energy is too low. Wave water particles oscillate and displace to generate potential energy. Wave energy is one of the most abundant, most common, and energy-dense energy in ocean energy, accounting for the largest proportion of ocean energy. It is estimated that the wave energy in the world's oceans reaches 70 billion kilowatts, accounting for 94% of all ocean energy.

[0004] Chinese patent 2023112081102 proposes a seawater wave generator set, which uses a cam-shaped float with a water inlet, a water outlet and a wheel cavity. The waves entering through the water inlet drive the blades in the wheel cavity to rotate, thereby converting the waves into electrical energy. However, the blades in the wheel cavity are in direct contact with seawater. Due to the long-term parasitism of seaweed and marine organisms on the blades, as well as the corrosiveness of seawater, the wheel cavity rusts, greatly reduces the rotation efficiency of the blades, reduces the reliability of the motor, and increases the maintenance cost of the entire device.

[0005] Chinese patent 2019102027213 proposes a swing power generation device that uses a gravity ball to swing horizontally and vertically to drive the gears on two shafts to rotate, thereby converting it into electrical energy. However, this invention directly converts the kinetic energy of the gravity ball into electrical energy. If the device is subjected to uneven swing, it will directly lead to unstable power generation and even energy loss, greatly reducing the reliability of the motor.

[0006] Therefore, the technical problem to be solved by the embodiments of the present invention is to overcome the defects of the prior art such as the inability to resist seawater erosion and unstable energy conversion, thereby providing a new fully enclosed generator with stable power output. Summary of the invention

[0007] A fully enclosed wave engine provided in an example of the present invention comprises: an energy storage mechanism, a speed control mechanism, a speed regulating mechanism, a power generation mechanism and a fixing device for installation, as well as a casing and a sealing cover which are connected in sequence.

[0008] Preferably, in the energy storage mechanism, the pendulum makes a circular motion in a single direction around the ratchet shaft under the action of the pawl and the ratchet gear, and the mechanical energy generated by the pendulum motion is transmitted to the coil spring through the ratchet shaft, causing the compression of the coil spring to be converted into elastic potential energy. During the coil spring release process, the coil spring box is fixed by the coil spring end and the coil spring box to drive the coil spring box to make a circular motion in the opposite direction of the ratchet gear. In this process, the elastic potential energy of the coil spring is converted into mechanical energy and transmitted to the speed control mechanism through gear shaft two.

[0009] Preferably, in the speed control mechanism, the escapement wheel, the pallet fork, the balance wheel, and the hairspring form an escapement system. The balance wheel and the hairspring generate periodic oscillations through the mechanical energy provided by the energy storage mechanism, and their energy loss is replenished by the slips of the pallet fork. The pallet fork of the escapement mechanism has two slips, one of which drives the escapement wheel to rotate, and the other plays a role in preventing the escapement wheel from reversing. The intermittent motion frequency is stable, so that the escapement mechanism can move continuously and accurately and regularly, thereby achieving the purpose of speed control. Gear 4 moves in a circular motion around a wheel axis coaxially and at the same speed as the escapement wheel, and transmits the accurate and regular mechanical energy provided by the escapement mechanism to the speed regulating mechanism.

[0010] Preferably, in the speed regulating mechanism, gear 3 and gear 2 are coaxially arranged, and gear 3 and gear 4 are meshed with each other, thereby obtaining that the linear speeds of gear 3 and gear 4 are consistent, and the angular speeds of gear 3 and gear 2 are consistent. By controlling the gear ratios of gear 3 and gear 2, and gear 3 and gear 4, the purpose of acceleration and deceleration is achieved, and low power generation efficiency caused by insufficient power or overload of the generator is prevented.

[0011] Preferably, gear one and gear two in the power generation mechanism mesh with each other, transmitting the regular and appropriate speed mechanical energy in the speed regulating mechanism to the generator, so that the generator operates to achieve the purpose of power generation.
