An adaptive seawater hydraulic system applied to a pendulum wave power generation device

Abstract

The invention discloses an adaptive seawater hydraulic system applied to a pendulum wave energy power generation device, which is provided with a seawater pump, a flow regulating valve, a high-pressure hose, a manual reversing valve and a hydraulic motor in sequence along the seawater flow direction, and is characterized in that , There is a seawater filter at the seawater inlet end, a seawater monitoring module is arranged in the seawater filter, a main controller and a system parameter adjustment module are arranged in the seawater pump, and the seawater monitoring module and the system parameter adjustment module are connected with the main controller Electrical connection. The hydraulic system can monitor the front-end water quality of the seawater entering the system. After comparing with the set value in the main controller, the corresponding adjustment module is driven to adjust the water quality to ensure that the seawater properties at the motor drive stage are the most suitable for the operation of the system. , to overcome the defects of seawater itself, such as strong corrosiveness, unstable pressure, easy to freeze, etc., while making full use of wave energy, minimizing the loss of hydraulic system, and helping to prolong the service life of power generation equipment.

Description

technical field [0001] The invention belongs to the technical fields of renewable energy and energy conservation and environmental protection, and in particular relates to an adaptive seawater hydraulic system applied to a pendulum wave energy power generation device. Background technique [0002] Due to the combined effect of various factors such as the growth of global energy consumption, the demand for a low-carbon economy, the depletion of fossil fuels, and the oil economy, people are eager to find new technologies that are greener and can replace traditional energy. Ocean energy accounts for more than 70% of the world's total energy. Ocean energy is an important renewable energy source. Part of the wind energy is stored in the ocean in the form of wave motion. The energy density of ocean wave motion is very high and spreads in the ocean. Extensive, and because of this, harnesses the energy of waves even thousands of miles away from the ocean. [0003] Compared to solar...

Problems solved by technology

However, after this type of device is actually put into use, due to the characteristics of strong corrosion, low viscosity, poor lubricity, high pressure resistance, and seawater freezing of seawater, it will cause unpredictable damage to power generation equipment after long-term use. The mobility and flexibility of marine development equipment need to be further improved
