Embodiment 1

[0026] Such as figure 1 As shown in -6, a wave energy absorbing device for an unmanned monitoring ship includes at least two buoyant tanks 1 connected to each other. A conversion device 10 is provided in the buoyant tank 1, and the conversion device 10 passes through the swing rod 5 on the side of the buoyant tank 1. It is connected with the swing plate 6 arranged under the buoyant tank 1, and the side of the buoyant tank 1 is provided with a floating block 2, and the floating block 2 is connected with the buoyant tank 1 through two connecting rods 3 to form a triangular structure. The device of the present invention can realize the unmanned monitoring ship by connecting the unmanned monitoring ship with the buoyant tank 1, and the conversion device 10 in the buoyant tank 1 relies on the swing plate 6 to be impacted by the water flow to generate swings to convert energy into the unmanned monitoring ship for energy supply. The monitoring work is carried out in the area, and the...

Embodiment 2

[0036] When the wave energy absorbing device of an unmanned monitoring ship of the present invention is actually used: place the buoyancy tank 1 on the sea surface 4, install and connect components such as the swing rod 5, the swing plate 6, the bracket 7, and the counterweight 8 in sequence, and connect The ring 1a and the rope connect the unmanned monitoring ship to the buoyancy tank 1, and the conversion device 10 in the buoyancy tank 1 relies on the swing plate 6 to be impacted by the water flow to generate swings to convert energy into the unmanned monitoring ship for energy supply, so that the unmanned monitoring ship can operate monitoring in the area.

Abstract

The invention discloses an unmanned monitoring ship wave energy absorption device, and belongs to the technical field of sea energy utilization. The device comprises at least two connected buoyancy tanks. Conversion devices are arranged inside the buoyancy tanks. The conversion devices are connected with a swing plate arranged below the buoyancy tanks through swing rods at the sides of the buoyancy tanks. Floating blocks are arranged at the sides of the buoyancy tanks. The floating blocks and the buoyancy tank form triangular structure connection through two connecting rods. According to the device, the problem that the stability and the power generation efficiency are affected when a wave power generation device is subjected to transverse oscillation in the power generation process can besolved, the energy conversion rate is high, and the device is long in service life and low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of ocean energy utilization, and in particular relates to a wave energy absorbing device for an unmanned monitoring ship. Background technique [0002] Due to the depletion of non-renewable energy such as global fossil energy and the increasing environmental pollution, the effective use of clean and renewable energy has become an important choice for the energy strategy of the world's major coastal countries. Wave energy is mainly used for power generation, providing clean energy for national defense and marine facilities in remote sea areas. In addition, wave energy can also be used for water pumping, heat supply, seawater desalination, and hydrogen production, etc. However, at present, wave energy has the characteristics of poor stability, resulting in low energy utilization efficiency and poor operation stability of wave energy power generation systems. If this kind of ocean energy is fully developed and...
