Wave-force power generation method and wave-force power generation device

Abstract

The invention relates to a wave-force power generation method and a wave-force power generation device. For the method, the wave-force power generation device consists of a maritime part and a shore-based part, wherein the maritime part is a wave force machine of which rollers at the lower end of a machine frame runs on a rail of the machine frame, so that the wave force machine can be placed under the sea or onshore. A wave gathering cover of the wave force machine gathers wave energy in a suitable compression ratio, and sends the wave energy to a plurality of different energy gathering cylinders, according to the water yield of the control signal water drain openings of the energy gathering cylinders with the control function, wave heights control the running states of the energy gathering cylinders to enter or withdraw from a combined equivalent energy gathering cylinder so as to output mechanical energy, pneumatic energy and hydrodynamic energy which are output in a complementary and stable manner, and after being supercharged and stored, the mechanical energy, the pneumatic energy and the hydrodynamic energy are sent to the shore-based part under the control of a rotating speed testing and controlling device; namely the mechanical energy, the pneumatic energy and the hydrodynamic energy are sent to inlets of an air turbine and a water turbine in an ashore machine room through pipelines so as to drive the rotating speed and the torque of a transmission main shaft according to the size of the wave heights, and the rotating speed testing and controlling device is coupled with the transmission main shaft through a plurality of independent overrunning clutches arranged on generators so as to allocate the gathered energy of the wave gathering cover to be matched with a loaded power generation set. The wave-force power generation device disclosed by the invention is designed by the method.

Description

technical field [0001] The invention belongs to the technical field of new energy, and specifically relates to a method for large-scale development and utilization of wave energy and a wave power generation device that is environmentally friendly and has no adverse effects on geological and ecological balance. Background technique [0002] The more developed regions or countries have higher requirements for energy cleanliness, especially the awareness of protecting geological and ecological balance is gradually strengthened. For the construction of large-scale barrage dams for water storage and power generation on large rivers, the changes in the water volume distribution of the above-ground and underground water systems correspond to the changes in the distribution of crustal mass. Crustal mass distribution is the most important basic parameter of geological ecology, and it is also one of the important and key factors affecting the crustal movement and geodynamic state. Th...

Problems solved by technology

What are the defects? The first defect is that the hydraulic fluid is replaced by the gas working fluid, and the energy carried by the working fluid is reduced by 775 times only by the change of the working fluid; Shore waves only absorb a small part of the surge energy at a certain depth under the water layer, that is, no matter how high the energy absorption efficiency of the energy pickup is, the energy it can absorb will never exceed half of the energy carried by the waves; The third defect is that the adverse effect of the tidal range on energy pickup is not eliminated, and the size of the tidal range is additionally increased in the size of the wall, so that during the high tide period, the energy pickup efficiency of the surge wave is lower; the fourth defect is that the air chamber cavity High engineering requirements, no air leakage

However, the connection area between the gas chamber and the turbine belongs to an open area, and a large amount of compressed gas leaks from here, and this loophole cannot be blocked.

Because it also has the function of an air inlet; defect 5, the air chamber is used as an energy pick-up device, its sensitivity is extremely low, it cannot absorb the energy of small waves, and it cannot make the generator set run stably at the rated power; defect 6, gather energy The energy pickup ratio is extremely low, resulting in an extremely low conversion rate between gas energy and electric energy. Even when the air pressure is lower than the static friction threshold during the start-up of the transmission components, the turbine cannot be rotated; defect seven, the air chamber If there is no air storage bag, its combination is poor and the utilization rate of the sea area is low; defect 8, as long as there is no joint operation of multiple oscillating air column chambers, it is impossible to achieve the same wave fluctuation characteristics between energy-absorbing units. Complementary advantages, it is difficult for the generator set to enter the state of generating power under the rated power condition, and it is in the state of "less rotation and more stop"... Its defects should not be listed one by one
