The utility model is characterized in that the cold water supply system consists of a well hole, a well hole platform, a storage tank an a plurality of axial-flow pump sets; the well hole platform is formed by steel frames being inlaid with foams, the lower surface of the well hole platform is fixed to the well hole and the upper surface is provided with the storage tank and the plurality of axial-flow pump sets; the water pump head of the axial-flow pump set is arranged in the well hole and a water outlet is communicated with the storage tank; the net cage sets are respectively fixed on the rack and the periphery of the net cage sets are provided with a ring of heat-insulation wall; the top surface of the rack is provided with a circular water channel which is provided with a water drainage channel communicated with each net cage; the water channel is communicated with the storage tank. The utility model is advantageous in that water of low temperature at the deep level of the well hole is pumped by the axial-flow pump set and is conveyed to each net cage which adopts the heat-insulation wall, thereby water in the net cage can be cooled down to meet the requirement of cold water fish to pass summer; the trouble that cold water fish is moved in and out of the water to pass summer is resolved; death rate in the moving process is greatly reduced; fish can be normally fed and grow.
Description
Technical field
The utility model relates to fish cultivating system, is specifically related to the cold water fish net cage system of aestivating.
Background technology
The high temperature resistant limit of cold water fishes such as sturgeon is 28 ℃, is higher than this water temperature, and fish will be difficult to survival.And south is at high temperature season, and the dark lake water temperature of 1-6 rice is between 30 ℃-34 ℃ even higher, and therefore in southern reservoir lake, pool, the large-scale farming cold water fish must take measures to carry out " breed of aestivating ".
Traditional method of aestivating: build the cement fishpond on the coast, from reservoir (or rivers and lakes), get depths cold water, be extracted in the fishpond of aestivating on the bank, adopt the mode of aestivating of fish culture in running water in the big flow exchange pond.There is following shortcoming in this mode of aestivating: it is huge that (1), fish are transported to the finish engineering that moves back to net cage again of the pond and aestivating of aestivating from reservoir, lake net cage, and the lethality of fish is very high; (2), because the cultivation density in pond of aestivating is bigger, water temperature can only be thrown something and fed fish meal again on a small quantity to keep its life about 25 ℃, during therefore aestivating (general 4-5 month), fish does not only increase weight on the contrary can loss of weight.
The utility model content
The problem of aestivating and culture existing at above cold water fish, the utility model provides a kind of cold water fish net cage system of aestivating, comprise some net cage groups and Cold water supply system, each net cage group is made up of a plurality of net cages respectively, described Cold water supply system comprises pit shaft, the pit shaft platform, water storage box and some axial-flow pump groups, the degree of depth of described pit shaft is a 16-30 rice, its top is fixed on the lower surface of pit shaft platform, the pit shaft platform is inlayed foam by steel frame and is formed, the pit shaft platform is provided with water storage box and some axial-flow pump groups, and the water pump head of axial-flow pump group is installed in the pit shaft and delivery port communicates with water storage box; Every networking case group be fixed on the bottom surface of support respectively and the net cage group around be equipped with a circle insulated wall, be provided with annular water channel around the end face of support, and water channel is provided with the drainage ditch that communicates with each net cage respectively, water channel communicates with water storage box.
In such scheme, the barrel of described pit shaft is steel plate or fiberglass or PVC matter material.
In such scheme, described pit shaft the top barrel be steel plate, the bottom barrel is a fiberglass.
In such scheme, described pit shaft the top barrel be steel plate, the bottom barrel is the heat insulation canvas of PVC.
In such scheme, the height of described pit shaft is 18 meters, and the height of top barrel is 12 meters, and the height of bottom barrel is 6 meters.
In such scheme, the material of insulated wall is PVC canvas, PVC plate or fiberglass.
In such scheme, the distance between divider wall and the net cage group outer wall is 30-50 centimetre, degree of depth 10-15 rice.
The utility model, draw up and be transported in each net cage that has adopted insulated wall by the water at low temperature of axial-flow pump group the pit shaft deep layer, water in the net cage is lowered the temperature, satisfied the requirement that cold water fish is aestivated, removed from every year on the bank bank get off to backhaul fish and aestivate, not only saved cost of transportation but also greatly reduce because carrying causes the lethality of fish.Simultaneously, fish can normally be thrown something and fed, normal growth.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the utility model comprises two net cage groups 1 and Cold water supply system, each net cage group 1 is made up of 12 net cages 11 respectively, each independently net cage be used for supporting cold water fish, the size of net cage and quantity are decided according to the breed scale, and each net cage is of a size of 6 * 6 * 6 meters in the present embodiment.
The Cold water supply system comprises pit shaft 2, pit shaft platform 3, water storage box 4 and two axial-flow pump groups 5, pit shaft 2 can adopt square or circular configuration, material can adopt steel construction, steel and PVC canvas combining structure or steel and fiberglass combining structure, the size of pit shaft and quantity are decided according to the breed scale, this example size is long (4-10 rice) * wide (4-10 rice) * dark (16-30 rice), in the present embodiment, the height of pit shaft 2 is 18 meters, the height of top barrel 21 is 12 meters, the height of bottom barrel 22 is 6 meters, the lower end employing of pit shaft 2 is cast anchor or the hanging killagh is fixed, and the top of pit shaft 2 is connected on the pit shaft platform 3, and pit shaft platform 3 is inlayed foam by steel frame and formed, foam size is 6 meters * 6 meters, 1 meter of thickness, the buoyancy of dependence pit shaft platform 3 is kept afloat pit shaft 2.Water storage box 4 and two axial-flow pump groups 5 are separately positioned on the pit shaft platform 3, and the water pump head of axial-flow pump group 5 is installed in the pit shaft 2, and delivery port communicates with water storage box 4, so axial-flow pump group 5 draws up the water at low temperature of pit shaft deep layer come and is transported in the water storage box 4.The quantity of axial-flow pump group, power, flow are decided according to culturing needs, are 30kw, per hour 1700m in the present embodiment
