gravity balancer

Abstract

The invention provides a gravity balancer which comprises a support, a swing vibrator and an elastic mechanism and is characterized by also comprising a rail, wherein the rail comprises an upper fixed rail and a lower movable rail positioned below; the fixed rail is fixed on the support without moving, and the movable rail is articulated with the support by virtue of a branch hinged shaft; the swing vibrator is in rigid connection with the movable rail, and the elastic mechanism is straddled between the upper fixed rail and the lower movable rail; the upper end and lower end of the elastic mechanism are respectively connected with the fixed rail and the movable rail in a sliding or rolling manner, and the fixed rail is in the shape of a level beeline or a curve; and the floating rail is in the shape of a curve, and the curve shape is obtained by virtue of a force equation or an energy-balance equation or topological optimization. The balancer provided by the invention has the advantages of eliminating the influence of gravitation on a vibrating energy absorbing system and providing a condition for the vibrating energy absorbing system to form a resonance state, thereby providing afoundation for realizing high-efficiency vibrating energy absorbing system.

Description

technical field [0001] The invention relates to a vibration energy-absorbing wave power generating device, in particular to a gravity balancer for eliminating the influence of gravity on the vibration of an energy-absorbing pendulum vibrator. Background technique [0002] Wave power is the use of energy from ocean waves to generate electricity. The energy of ocean waves exists in the form of waves. In order to utilize the energy of ocean waves, the wave power generation device absorbs the energy of ocean waves, converts it into mechanical energy, and then converts the mechanical energy into other forms of energy to generate electricity. [0003] In wave power generation devices, the most direct way to absorb wave energy is to use waves to cause vibrations in the energy-absorbing system to achieve energy absorption. The energy absorbed from the waves is greatest when the energy absorbing system is in resonance. Due to the long cycle of ocean waves, the generally available w...

AI Technical Summary

Problems solved by technology

However, because the characteristics of ocean waves change from time to time, it is very difficult to achieve resonance of the energy-absorbing system

One of the difficulties is that gravity causes the system to be in a strong nonlinear state during large-scale vibration, and it is difficult for the system to achieve resonance

That is to say, the pendulum vibrator is always under the action of gravity during the up and down movement, and there is no force to completely or partially balance the action of gravity, which makes it difficult for the energy-absorbing system to form a resonance state, and the energy-absorbing efficiency is low
