Description

Technical Field

[0001] The present invention relates to the technical field of new energy power generation equipment, in particular to a tidal energy power generation device. Background Art

[0002] With the progress of society and the improvement of people's quality of life, people's consumption of fossil energy is becoming more and more huge, but the total amount of fossil energy is limited, so people have been studying the topic of the use of new energy in recent years, and tidal energy is a kind of new energy utilization. The use of tidal energy will be less dependent on fossil energy. The tidal energy of the sea is extremely rich. The greater the water level difference between high tide and low tide, the greater the energy glare. All the heat energy generated by the water level difference caused by the rise and fall of the tide can be used to generate electricity. Wave energy and tidal energy have good development and utilization value, so all countries in the world attach great importance to and spend a lot of effort on research and development, especially research and development of wave energy power generation devices. Tidal power generation belongs to the category of new energy. Tidal power generation is also in the stage of gradual promotion in my country.

They use the intermittent impact of tides to generate electricity, or the motor needs to repeatedly switch between forward and reverse directions. This power generation principle has low energy utilization efficiency, which makes it impossible for the drive components to be continuously impacted by tidal energy and cannot fully utilize tidal energy, affecting power generation efficiency and reducing performance.

The water spraying device is arranged at the bottom of the inner wall of the shell and is located between the pressure plate and the arc-shaped elastic plate. The impeller is fixed on the surface of the main shaft and close to the end of the water spraying device.

[0014] (III) Beneficial effects

[0015] The present invention provides a tidal energy power generation device having the following beneficial effects:

[0016] (I) The tidal energy power generation device, through the shell, the power generation mechanism, the tidal energy conversion device, the main shaft, the pressing drive device, and the rebound drive device, uses the tidal energy conversion device to convert tidal energy into mechanical energy, and then generates electricity through the power generation mechanism, making full use of the impact of tidal energy, and can make the power generation drive mechanism continue to operate, so that the power generation efficiency is high, and the work efficiency and performance are improved.

[0017] (ii) The tidal energy power generation device comprises a pressure plate, an arc-shaped elastic plate, a water spraying device, an impeller and a rebound driving device. When the tide impacts the pressure plate, the arc-shaped elastic plate is pressed as the pressure plate rotates. At this time, the pressure plate and the elastically bent and deformed arc-shaped elastic plate jointly apply pressure to the water spraying device, and make it spray water quickly to the impeller. The high-speed rotation of the impeller is utilized to drive the main shaft, thereby achieving the purpose of power generation. At the same time, when the tide recedes, the elastic force of the arc-shaped elastic plate bounces the pressure plate. At this time, the water spraying device absorbs water. At the same time, under the pull of the top of the pressure plate, the rebound driving device works, so that the main shaft continues to rotate without stopping, thereby improving the power generation efficiency and making full use of the tidal energy. The whole device is connected together, which is safe and reliable, and has improved performance.

[0018] (III) The tidal energy power generation device includes a water bag, a flat nozzle, a water inlet pipe, a water inlet check valve and a water outlet check valve. When the water bag is pressed by a pressure plate, the water inlet check valve and the water outlet check valve are used to control the water inlet and outlet. The water bag will quickly spray out to the impeller through the flat nozzle, and the impeller will be driven by the impact force of the water pressure, thereby driving the main shaft to generate electricity, thereby making full use of tidal energy.

[0019] (IV) The tidal energy power generation device comprises a pressure plate, a driving rack device, an arc-shaped tension spring and a ratchet. When the pressure plate is impacted by the tide and rotates clockwise, the water bag is pressed to spray water, and then the main shaft is driven by the impeller. At the same time, the ratchet slides on the ratchet and does not work. When the tide recedes, the arc-shaped elastic plate bounces the pressure plate, the water bag absorbs water, and at the same time the driving rack device is pulled, the ratchet drives the ratchet to rotate, so that the main shaft continues to rotate, thereby achieving a continuous rotation effect. The arc-shaped tension spring provides tension, which can make the driving rack device and the ratchet cooperate stably, making the entire structure safer and more reliable.

[0020] (V) The tidal energy power generation device, through the base plate, ratchet, arc spring, and stopper, utilizes the rotatable ratchet to stably fit with the ratchet wheel under the action of the elastic force of the arc spring, and the stopper can rotate on the base plate together with the ratchet. On the one hand, it can make the rotation of the ratchet more stable, and on the other hand, it can limit the rotation of the ratchet. When the ratchet wheel is pushed, the supporting strength is improved, thereby achieving the effect of multiple functions and improving the performance of use. BRIEF DESCRIPTION OF THE DRAWINGS
