Problems solved by technology

There are multiple difficulties in the operation of large-area microalgae bioreactors on open water, such as installation on the water surface, water filling and drainage, cleaning, ventilation, temperature adjustment, wind and wave resistance, etc.
Currently, there is a lack of microalgae bioreactor designs for large-scale application in open water

Embodiment 1

[0075] Example 1: Construction of a floating support structure with a "floating tube" pipe section and a "live bottom" cable bottom bracket section. The pipe part is connected by PPR hot-melt pipe through hot-melt sealing, and the middle ventilation is used as a part of the load-bearing floating pipe and gas distributor; the interval uses a wire-reinforced polyvinyl chloride hose as an elastic sleeve to connect the PPR pipe. The support part of the "live bottom" bottom bracket is made of fiber reinforced polyvinyl chloride pipe with a cable jacket, and the floats arranged in a grid form form a strip network structure; the pile cable is made of fiber reinforced polyvinyl chloride material, with a diameter of 10-12 mm (1000 -1500 shares), the length is about 2 to 3 times of the water depth at high tide, and the floats are glass fiber balls or plastic balls; the piles are buried in sand and mud on the seabed. The structural shape of the pipeline units perpendicular to the water s...

Embodiment 2

[0076] Example 2: The part of the self-floating pipeline is connected by PPR hot-melt pipe through hot-melt sealing, and the middle ventilation is used as a load-bearing floating pipeline and a gas distributor. The shape of the pipe support unit structure is circular, and it is repeatedly arranged in parallel along the water surface and connected to each other to form a grid-like pipe support structure, and elastic connection or movable connection can be used between them. A plurality of light-transmitting round plastic boxes are used as culture containers and are located in the middle of the round pipe support. The top wall of the plastic box culture container can be separated from the bottom wall for easy cleaning and installation. The floating rope structure adopts the form of ropes and chains to connect the culture container and the pipe support in a movable manner, and bears the bottom of the culture container; different culture containers and horizontal pipe supports ris...

Embodiment 3

[0077] Example 3: The metal wire is used to strengthen the ventilation in the middle of the polyvinyl chloride pipe as the load-bearing floating pipe and gas distributor in the pipe support part. The pipe unit structure that is repeatedly arranged perpendicular to the water surface is shuttle-shaped, and is repeatedly arranged along the direction parallel to the water surface and connected to each other to form a tubular pipe support structure. The streamlined structure of this structure on the water surface can support the top of the culture container higher than the water surface, which is convenient for ventilation and maintains the transparency of the top; Regularly arranged groove structure. The streamlined structure under the water surface can be drilled as a part of the gas distributor; it can also be connected to the air stone through the air nozzle and installed on the arc top pipe support on the water surface as a gas distributor. The top light-transmitting plastic ...

Abstract

The invention relates to a device for water-surface aquaculture engineering, which is applied to the large-scale culture of algae, mussels, abalones, sea cucumbers, crabs, fish and shrimps on open water surface such as sea surface. The device comprises a net-shaped base support formed by ropes with floaters in spaced regular arrangement, a support formed by pipes, a pile-cable unit, and a culture vessel supported by the supporting units and fixed by the pile-cable unit. The net-shaped base support with floaters is fully or partially separated from the culture vessel and other floater supports, thereby forming a 'floating-pipe movable base' culture device. The pipe-based support has multiple units in geometric shape. The multiple units of the pipe-based support are in detachable arrangement and connected to one another, and serve as gas passages to form a part of a gas distributor. The device is applied to the large-scale culture of aquatic animals on open water surface and has the advantages of low cost, firm structure, resistance to wind and waves, and convenience for installation and removal of large-area culture vessels.

Description

technical field [0001] The invention relates to the technical field of water surface cultivation, in particular to a cultivation device for large-scale cultivation of single-cell algae, macroalgae, shellfish, abalone, ginseng, sea urchin, crab and fish and shrimp on the open water surface, especially the sea surface. Background technique [0002] Large-scale cultivation of aquatic organisms, such as macroalgae and unicellular algae, is used for biomass energy production, high-protein grain production, feed, bait, chemical fertilizer, and for high-nitrogen and phosphorus wastewater treatment for aquaculture, and carbon dioxide emission reduction. extensive attention. At the same time, due to the limitation of land area, the aquaculture area of ​​biomass energy and grain bait needs to expand to the sea. The traditional aquaculture raft is an important engineering technical equipment for marine aquaculture. The raft farming raft frame is mainly composed of pile cables, floati...
