Wave power generation device with anti-overload function

Abstract

The invention discloses a wave power generation device with an anti-overload function, and relates to the field of wave power generation devices, the wave power generation device comprises a power generation device and a piston rod component, the piston rod component is arranged in the power generation device, the piston rod component comprises a first rod and a second rod, and ball grooves are formed in the connecting positions of the first rod and the second rod. Through an upper limiting disc, a lower limiting disc, a lifting groove, a reset spring, a piston disc and the like, the situation that when the wave direction is irregular, a piston cylinder part is damaged by extreme weather is avoided, the wave direction indicator is influenced by the wave direction to drive a second rod to rotate, the second rod drives the piston disc to rotate, and due to the fact that the piston disc is limited by a sliding groove and a sliding rail, the piston disc is prevented from being damaged. Therefore, rotation force of the piston disc is converted into vertical movement force, abnormal movement of the piston disc in extreme stormy weather is avoided through the measure, and meanwhile the situation that when the piston disc moves abnormally, a large amount of seawater enters or gushes out, and consequently the loading limit of the interior of the piston cylinder component is avoided.

Description

technical field [0001] The invention relates to the field of ocean wave power generation devices, in particular to an ocean wave power generation device with an overload prevention function. Background technique [0002] The depletion of traditional energy sources and the deterioration of environmental pollution make the development of new energy sources imminent. With the development of low-power wireless sensors, it is increasingly It has received widespread attention from all walks of life. Compared with wind energy and solar energy technology, wave energy power generation technology is more than ten years behind, but wave energy has its unique advantages. The energy density of wave energy is high, which is 4~30 times that of wind energy. Compared with solar energy, wave energy It can not be affected by the weather. Its power generation system uses the rising and falling movement of seawater to make the buoy drive the piston chamber to move up and down. Through the contin...

Problems solved by technology

[0003] Although wave power generation has many advantages, most of the current wave power generation equipment is relatively large in size and has high costs in production and installation. The near land and shallow sea area is relatively more suitable for power generation devices that are small in size and easy to install on a large area. The reduction in size can not only solve the geographical constraints of shallow sea areas, but also facilitate installation and maintenance, as well as the flexible use brought about by size advantages. Although small power generation devices in shallow sea areas have the advantages of low production costs, convenient transportation, and high installation efficiency, However, due to the limited size, the ability to deal with extreme weather is limited, and it is easy to be overloaded when the tide is high or the tide is rough. These problems are the main problems that endanger this type of device;
