Description

Single floating tube submersible floating intensive marine treasure cultivation device

technical field

The invention relates to the field of marine aquaculture facilities, in particular to a submersible and buoyant intensive sea treasure cultivation device with a single floating tube.

Background technique

In recent years, with the rapid development of my country's economy and the continuous improvement of people's living standards, people's demand for sea treasures is also increasing, thus promoting the development of sea treasures breeding industry.

Sea treasures—sea cucumbers, abalones, sea urchins and other bottom-dwelling marine organisms are generally cultured in the following ways: raft culture, subtidal caisson culture on rocky reefs, enclosed pond culture in intertidal zones, subtidal culture with stone nets, and land-based factories methods such as chemical breeding, bottom broadcasting and streaming multiplication.

Because raft farming needs to adjust the water layer with the change of seasons and sea conditions, sometimes the ropes of the cages are very long, and the irregular water flow can easily cause the mutual entanglement of the breeding cages, which will bring losses to the breeding production; the other is the load of the farming raft frame It is very large. If the weather is bad, the waves are strong and the current is fast, the force of the raft frame will be increased due to the force of the waves and currents, and there is a danger of being uprooted at any time. In caisson farming, reefs are added to the caisson and sunk to the bottom of the water, which makes the work of inspection, feeding, and removal of harmful organisms more cumbersome. It is necessary to use a larger boat with a boom to lift the caisson to the ship for operation, which is more convenient for offshore operations. Management is inconvenient. The operating cost of factory farming is high, the investment in facility construction is large, the energy consumption of large-scale production is large, and the quality and growth speed of sea treasures are not higher than those in natural sea areas. Pond aquaculture and subtidal aquaculture are also plagued by problems such as susceptibility to offshore seawater environment pollution, large water temperature changes, high disease rates, and short aquaculture cycles.

Therefore, research on an efficient submersible and floatable deep-water layer marine intensive device or facility, so that it can expand the breeding sea area to the deep sea, and take advantage of the advantages of deep sea water clarification, smooth tide, relatively stable water temperature, rich bait, and no pollution , Breeding green and pollution-free breeding products in line with the national advocacy. Compared with the above-mentioned traditional farming models, it has a higher survival rate and better product quality, so its development is imperative.

Detailed ways

Below in conjunction with the embodiment, the single-floating tube submersible floating intensive marine treasure cultivation device of the present invention will be described in more detail.

Fig. 1 is a side view of a single-floating tube submersible-floating intensive marine treasure cultivation device of the present invention, and Fig. 2 is an end view thereof.

The single-floating-tube submersible-floating intensive marine treasure breeding device of the present invention: a single high-density polyethylene pipe is used as a floating tube 1, a rack-shaped steel structure cage 2, and a block-shaped polymer cage bound on both sides of the cage. Ethylene foam float 3, special box for polyethylene sea treasure breeding 4, sling 9, hanging sinker at the bottom of steel cage frame 5, filling and exhausting port 6, filling and exhausting hose 7, inlet and outlet pipe 8; Both ends of a single floating tube 1 are closed with high-density polyethylene pipe fittings as a floating tube cabin. On the upper side wall of one end of the floating tube cabin, a charging and exhausting port 6 is welded, and the charging and exhausting port 6 is connected to the charging and discharging port. Pipe 7, filling and exhausting pipe 7 adopt high pressure-resistant rubber pipe material to make, and the upper end of filling and exhausting pipe 7 is provided with floater and control valve, can realize remote control diving control.

In the lower part of the other end of the floating tube cabin, inlet and outlet nozzles 8 are set; then every group of pannier-shaped cages 2 that have been prepared are bound to the floating tube 1 at intervals, because it is a panty-shaped design that can ensure that the floating tube 1. The center of buoyancy is above the center of gravity of the cage 2, and block polyethylene foam floats 3 are bound on both sides of the cage 2 to further ensure the vertical balance of the cage 2. The buoyancy of the foam floats 3 is slightly greater than that of each set of steel bars The gravity of the cage frame 2 of the structure; in the sea, multiple groups of cage frames 2 are carried on the rack at a certain interval and bound to a single high-density polyethylene pipe as the floating pipe 1, and the multi-layer polyethylene sea treasures are cultivated. Special case 4 is put into the cage frame 2 of steel structure, then at the bottom of the cage frame of cage frame 2 of every group of steel structure, hang sinking stone 5 at the bottom of the box with suspension rope 9, the size and weight of sinking stone will be according to the sinking and buoyancy force of whole device Calculated, specifically the gravity of each group of hanging sunken stones 5 will be slightly greater than the gravity difference of the cage frame of each group of foam float buoyancy and steel structure, according to the sea area bottom material situation and breeding requirements, adjust the length of suspension rope 9, reach Ability to stagnate in different water layers. The full-empty buoyancy of the floating tube 1 is greater than the total weight of each group of sunken stones, cage frames and culture box cages.

Technical safeguard measures: when the aquaculture device sinks into the bottom of the water and is in a stagnant state, it is necessary to ensure that the end of the high-density polyethylene floating pipe 1 close to the charging and exhaust port 6 is slightly higher than the end of the high-density polyethylene inlet and discharge pipe port 8; the safeguard measures are From the sling 9 at one end of the filling and exhaust port 6 to each sling at the end of the inlet and outlet pipe mouth 8, the same length decreases successively to form an arithmetic series.

In order to ensure that the aquaculture device is not washed away by the ocean current, the aquaculture device is anchored in the water by mooring at two points at both ends of the floating tube.

Open the control valve of the high-strength filling and exhausting hose 7, seawater enters the high-density polyethylene floating pipe 1 from the inlet and outlet pipe mouth 8, and the floating pipe drives the reinforced breeding cage frame 2 to sink into the sea successively from the water inlet to carry out underwater cultivation; When the cultivation device is floated to the water surface according to the cultivation requirements, the air compressor on board is utilized to inflate the high-strength inflation and exhaust hose 7 to realize the rising of the net cage.

The device was successfully tested in May 2010 in the sea area of Rongcheng Dongchu Island, the breeding base of Shandong Weihai Zhengming Ocean Technology Development Co., Ltd., and is ready to start the breeding and production of sea cucumbers and other sea treasures.
