Description
Technical Field
The utility model relates to a block fish equipment field, in particular to ship device is crossed in fish farming of block net.
Background
In China, a plurality of freshwater lakes, reservoirs, rivers and the like exist, natural baits in water are rich, the water is spacious and sunlight is sufficient, and unique conditions are provided for the development of the fish farming industry. In recent years, the industry of fish farming in lakes, reservoirs, rivers and the like has been greatly developed and the yield has been increasing. On one hand, water bodies of lakes, reservoirs, rivers and the like need to flow frequently due to flood discharge, irrigation, power generation and the like, so that cultured fishes often escape along with water flow; on the other hand, building fish blocking facilities in lakes, reservoirs, rivers and the like can block ships from passing through, and if the fish blocking facilities break down when the ships pass through the blocking net, the fishes can also escape. Therefore, the success or failure of fish farming and the smoothness of ship passage depends largely on the quality of the fish blocking facility.
When ships pass through the traditional net cage fish blocking equipment, the blocking net is usually manually pressed and sunk into water by using heavy objects such as sinking stones to allow the ships to pass through, then the heavy objects are removed or lifted, and the blocking net floats upwards to recover blocking. The traditional ship passing method has the following defects:
(1) the operation is clumsy, the working strength is high, the efficiency is low, and the traffic capacity or frequency is limited;
(2) the blocking net is difficult to sink into water, the depth is limited, and the blocking net is only suitable for small ships or ships with shallow draft to pass through, and can not pass through when meeting large ships or ships with deep draft;
(3) most of the blocking nets sink into water when passing through a ship, and the fishes are easy to escape.
In view of the above-mentioned drawbacks, the prior art proposes a solution, as disclosed in patent publication No. CN86208852U, to provide an automatic ship-passing device for inland water area fish-blocking and fish-farming, which comprises two floating boats, ropes for pulling down net sheets, and piers, and is mainly characterized by comprising a roof structure, two trapezoidal net sheets, and two floating boats 15 with supporting frames. Although the ship can automatically pass through the ship, the ship is complex in structure, large in investment and only suitable for passing small ships or ships with shallow draft.
The prior art also proposes another solution, as in patent publication No. CN103168755B, which discloses an electric and net combined fish blocking system and method, comprising net blocks, ship passing facilities, a plurality of grounds and electric catch-fish blocking units. Although the patent solves the traffic problem of large or deep-draft ships, the investment is larger and the structure is more complex; daily operation is troublesome, the operation cost of the electric fish blocking is high, and no rescue measures can be caused when the electric fish blocking facility breaks down.
Based on the above defects, the prior art needs to provide a device for blocking fish and passing through a ship to block fish and simultaneously have a ship passing function.
