Buoy and cylinder combination structure capable of covering whole tidal range and compressing air by utilizing wave energy

Abstract

The invention discloses buoy and cylinder combination structure capable of covering a whole tidal range and compressing air by utilizing wave energy, is designed for obtaining compressed air by utilizing the wave energy by using a buoy-cylinder combination in the whole ocean tidal range, and belongs to the field of ocean energy development and utilization. The buoy and cylinder combination structure capable of covering the whole tidal range and compressing the air by utilizing the wave energy comprises seven parts, namely, a telescopic cylinder, a locking cylinder, a working cylinder, a connecting pipe, a hinge, a buoy and a frame, which are connected in sequence, wherein the telescopic cylinder serves as the connection and fixation of the working cylinder, and achieves an effect of expanding and contracting along with the height change of ocean tide in the whole tidal range; the working cylinder realizes the functions of aspirating and compressing under the action of seawater buoyancyforce when the buoy rises and falls along with the wave, and exhausts the compressed air; the locking cylinder locks the telescopic cylinder in a rising process of the wave so that the height of thewave completely acts on the working cylinder; and the buoy is limited in the frame and can only perform vertical movement up and down along with the wave without being stuck.

Description

technical field [0001] The invention relates to a combination structure of buoys and cylinders that uses sea wave energy to compress air covering the entire tidal range, and converts sea wave energy into compressed air energy at the entire height of the ocean tide. [0002] technical background [0003] The ocean accounts for 71% of the earth's surface area, and there are waves and tides on the ocean surface. The energy of the waves mainly comes from the gravity of celestial bodies and wind energy, etc., which are always constant at all times; the tides are mainly related to the gravitational force of the moon and the sun on the earth. Generally, it is a relatively regular semi-diurnal tide, that is, once every 12 hours, and the tidal range varies with different sea areas. For example, the tidal range in my country has a tendency to gradually increase from north to south, and it has a large randomness. Ocean energy has laid the foundation for human beings to develop ocean ener...

Problems solved by technology

When the waves push the buoy-cylinder to obtain compressed air (the height between the cylinder and the seabed is fixed), with the tide rising and falling (the sea level changes), the buoy gradually rises or falls to shorten the piston stroke or the buoy loses buoyancy when it leaves the sea surface function and cannot effectively capture wave energy, resulting in insufficient or incompressible compressed air; the cylinder only compresses air within a limited height when the tidal range rises or falls, but cannot obtain compressed air throughout the tidal range, thus greatly reducing Wave Energy Utilization Efficiency
