Description
Technical field
The utility model belongs to fishery conservation technical field, particularly relates to the Flow Behavior experimental provision that becomes of a kind of Eriocheir sinensia seed.
Background technology
Eriocheir sinensia is that China common people enjoy a lot the aquatic products kind of tasting.Entrance of Changjiang River is the Eriocheir sinensia natural spawning site of China's maximum, germ plasm resource optimum.The nineties in 20th century, steamed crab culturist comes entrance of Changjiang River panic buying juvenile crab one after another, and natural juvenile crab was once sold for the tens thousand of units of per kilogram, and the juvenile crab that spawning ground, entrance of Changjiang River produces is being supported the high speed development of China's Eriocheir sinensis industry.When at the incoming tide, juvenile crab was traceed back river and went up, and now utilizes diddle-net, net bamboo weir, ship to choose the sampling works such as net and fish for regard to fisherman generally at the annual lunar calendar by the end of May the time that waters, entrance of Changjiang River juvenile crab plays flood.In addition, carrying out the method that juvenile crab fishes for also has miniflow water mass trapping, lamp light trapping method, copies laws on arrests etc.Breed and send out between flood season entrance of Changjiang River Eriocheir sinensia juvenile crab, accurately grasp the Flow Behavior feature that becomes of juvenile crab and fish for scientific research all significant for production.
Utility model content
Become during providing a kind of simple and easy to do definite Eriocheir sinensis seedling the to breed Flow Behavior experimental provision that becomes of Eriocheir sinensia seed of Flow Behavior feature of the utility model.
For solving the problems of the technologies described above, the Flow Behavior experimental provision that becomes of the utility model Eriocheir sinensia seed, comprising: migration groove, and described migration groove is rectangle, has the migration circuit that connects described migration groove in described migration groove; Water inlet pipe and outlet pipe, described water inlet pipe and described outlet pipe are separately positioned on the two ends of described migration groove, and are communicated with described migration circuit; And immersible pump, described immersible pump is arranged in described migration circuit.
Preferably, described water inlet pipe and described outlet pipe are arranged on the inner side of described migration groove.
Preferably, described water inlet pipe and described outlet pipe arrange in opposite directions.
Preferably, the diameter of described water inlet pipe and described outlet pipe is 5 centimetres.
Preferably, the material of described water inlet pipe and described outlet pipe is PVC plastics.
Preferably, the length of described migration groove is 3 meters, and width is 1 meter.
Preferably, the cross section of described migration circuit is rectangle, and 20 centimetres of its internal diameter width are highly 40 centimetres.
Preferably, on described migration circuit length direction, be provided with multiple designation strips.
Preferably, 1.2 meters of multiple described designation strip spacing.
The Flow Behavior experimental provision that becomes of the utility model Eriocheir sinensia seed is simple in structure, is easy to promote, and measurement result is illustrated the rule of Eriocheir sinensia seed to current demand in digital form, and measurement result is full and accurate accurately.

Embodiment
Below in conjunction with accompanying drawing, the Flow Behavior experimental provision that becomes of the utility model Eriocheir sinensia seed is described in further detail.
As shown in Figure 1, the Flow Behavior experimental provision that becomes of the utility model Eriocheir sinensia seed is made up of migration groove 6, water inlet pipe 2, outlet pipe 5, immersible pump 3, designation strip 1 etc.Rectangle migration groove 6 is made up of fiberglass disposal pouring, and long 3 meters, wide 1 meter, the cross section of migration circuit 4 is rectangle, and 20 centimetres of internal diameter width are highly 40 centimetres.Water inlet pipe 2 and outlet pipe 5 are respectively PVC plastic tube, and diameter is 5 centimetres, are arranged on respectively oval migration groove 6 two ends, when experiment starts, by water inlet pipe 2, water are injected, and when the depth of water in migration circuit 4 reaches 20 centimetres, water are closed.Immersible pump 3 power are 2 kilowatts, by its power of microcomputer chip control, thus the water velocity of control migration groove 6.Designation strip 1 is attached in the straight line circuit of migration groove 6, at a distance of 1.2 meters, experiment start time be divided into 4 equal portions (0 centimetre～30 centimetres, 30 centimetres～60 centimetres, 60 centimetres～90 centimetres, 90 centimetres～120 centimetres), each equal portions is 30 centimetres, measures 3 position flow velocitys of every part under different capacity and, as the mean flow rate of this part, compares the flow velocity of 4 parts, difference is not remarkable, shows that this straight line working region flow velocity is consistent.Be 20% by pump working power setting, now show after measured bottom water flow flow velocity approximately 5 cels of migration circuit 4.Select 30 of the wide 3 millimeters of young crabs of shell, with the string bag by list only young crab put into gently adaptation zone and adapt to flowing water environment 10 minutes, after adapting to, remove the string bag, young crab starts to creep, in the time that crossing 0 centimetre of designation strip 1, young crab starts with manual time-keeping, young crab stops timing while reaching 120 centimetres of designation strip 1 boundaries, in recording 120 centimetres, young crab creeps total time and (only adds up the adverse current young crab that creeps, 98% adverse current), then calculate average creep speed (centimetre/s), when finishing, experiment opens outlet pipe 5, by the water emptying of migration groove 6.For the Flow Behavior that becomes of the young crab of different size relatively, then to select respectively shell wide be each 30 of the young crab of 4 millimeters, 5 millimeters, 6 millimeters, 7 millimeters, repeats respectively above-mentioned test, and statistical analysis experimental result.Result shows, young crab has the Flow Behavior that becomes significantly, and in experimentation, 98% young crab adapts to start adverse current after 10 minutes and creeps in flowing water.The ability of creeping of young crab significantly strengthens with the wide increase of shell (3 millimeters～6 millimeters), but wide 6 centimetres of shell does not exist significant difference with the young crab locomitivity of 7 centimetres.This experimental result is fished for the research of juvenile crab resource and is all had certain reference significance for the production of entrance of Changjiang River juvenile crab.
The Flow Behavior experimental provision that becomes of the utility model Eriocheir sinensia seed is simple in structure, is easy to promote, and measurement result is illustrated the rule of Eriocheir sinensia seed to current demand in digital form, and measurement result is full and accurate accurately.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
