Embodiment 1

[0030] like Figure 1-9 As shown, a floating reef based on tidal current and wave power generation includes a bottom fish reef 1, the two ends of the bottom fish reef 1 are connected to a floating body 3 through a line 2, and several sets of generating units 4 are arranged on the floating body 3. Nets 5 are connected between the ropes 2, and an algae spore seeder 6 is arranged below the middle part of the nets 5. The main body of the floating fish reef is composed of floating body, rope, net, generator set and bottom fish reef as a whole. The water permeability, biological adhesion, structural safety and fish reef effect are very superior. Combined with the tidal power generation device and the floating body structure of the floating fish reef, the generator set located on the floating body of the floating fish reef can capture tidal current energy and wind wave energy well, and transmit them to the power generation device through rectification, realizing the conversion of oce...

Embodiment 2

[0039] In the actual use of the middle and upper layer floating fish reef based on tidal current and wave power generation of the present invention: put the fish reef into the water, the upper part of the reef body is provided with buoyancy by the floating body 3, and the power generation device 4 of the tidal current and wave current is fixed on the floating body 3, when the floating fish reef moves up and down with the waves, the tidal energy and wave energy are converted into electric energy by the generator set 4, which can provide power for marine equipment and offshore islands, and at the same time does not affect the breeding of fish in the net. When the algae spore seeder 6 arranged on the clothing 5 sinks to a certain water depth, the rubber sleeve 20 at the end of the algae spore seeder 6 will burst, and the algae spores 22 placed on the top layer will scatter to the surface or inside of the bottom fish reef 1. The spores 22 will rapidly multiply in large areas in the...

Embodiment 3

[0041] Contrast test: Before the floating fish reef of the present invention is dropped into a certain sea area in Zhoushan, use a 5L plexiglass water collector to collect 500ml of table and bottom water samples at 4 marked stations. In the same way as above, take another 500ml of surface and bottom water samples, and use a 0.45μm pore size mixed fiber filter membrane to filter a certain volume of samples with vacuum filtration equipment. After suction filtration, fold the filter membrane in half and put it into a numbered ziplock bag. , stored in an ultra-low temperature freezer (-20°C). In order to ensure that the samples are completely frozen, they can be extracted and measured after at least one day and night. This frozen sample can be stored for up to 3 months. Take an appropriate amount of 90% ethanol in a 1L beaker and preheat it in a temperature-controlled water bath. In a dark place at room temperature, extract the sample for 4-6 hours, and the longest time shall no...

Abstract

The invention discloses a pelagic floating fish reef based on tide and wave power generation and belongs to the technical field of marine ranch artificial fish reefs. The pelagic floating fish reef comprises a bottom-layer fish reef, two ends of the bottom-layer fish reef are connected with a floating body through steel ropes, a plurality of power generator sets are arranged on the floating body,a netting is connected between the steel ropes, and an algal spore seeder is arranged below the middle of the netting. The pelagic floating fish reef combines a wave energy and tidal energy power generation device with a floating body structure of a floating fish reef to realize primary conversion from ocean energy to electric energy and can attract fishes to gather, so that primary productivity of a sea area is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of marine ranch artificial fish reefs, and in particular relates to a mid-upper layer floating fish reef based on tidal current and wave power generation. Background technique [0002] my country's marine ranching is based on the principle of marine ecosystems. In specific sea areas, artificial fish reefs, multiplication and release are used to construct or repair places needed for marine organisms to grow, reproduce, feed, or avoid enemies, so as to proliferate and maintain fishery resources and improve the ecology of sea areas. environment and realize the sustainable use of fishery resources. As the golden key to solve the contradiction between the sustainable utilization of marine fishery resources and the protection of the ecological environment, the construction of marine ranching is an important exploration to transform the development mode of marine fishery, and it is also an important measure to promo...
