Embodiment
Below in conjunction with accompanying drawing, enforcement mode of the present utility model is described further.
As Figure 1-4, a kind of jet current fish-baiting instrument being applied to transporting something containerized fish system, it comprises collection fishing boat 6, the afterbody of the downstream Ji Yucangdao of collection fishing boat 6 is provided with fish inlet 5, head is provided with leads fish corral 10, in fish inlet 5 and the collection fish hold road led between fish corral 10, jet water jet standpipe 3 is installed, jet water jet standpipe 3 is provided with multiple ejector nozzle 4, described jet water jet standpipe 3 is connected with water conveyance steel tube 2, water conveyance steel tube 2 is connected with variable frequency pump 1, and variable frequency pump 1 is fixedly mounted in the ballast tank of collection fishing boat 6.
Further, described jet water jet standpipe 3 is arranged to road, cabin, upstream from the 10m place, road junction, transporting something containerized cabin, downstream of collection fishing boat 6, laterally arranges every 4m in collection fish hold road, arranges 5 rows; Longitudinally arrange every 0.6m downwards from collection fishing boat work plane orthogonal, arrange 6 rows.
Further, described jet water jet standpipe 3 adopts DN30 weldless steel tube material to make.
Further, described water conveyance steel tube 2 adopts DN50 weldless steel tube material to make.
Further, described jet water jet standpipe 3 and the Ji Yucangdao led between fish corral 10 are provided with and catch up with fish corral 8, and track 9 slides along pulling to catch up with fish corral 8, and close leading in the collection fish hold road of fish corral 10 is provided with fish-collecting box 7.
Concrete working process of the present utility model and principle of work be:
Jet fish-baiting instrument is arranged in collection fishing boat collection fish hold road, form high velocity flow, change the distribution of the flow velocity field of current in regional area before collection fishing boat import, form aobvious stream, change the original turbulent fluctuation distribution of current and size, directly affect the local flow field of the existence of fish, to form fish preferences flow condition at collection fish inlet 5 place, downstream, fish hold road, lead fish object with what reach attracting.
Jet current fish-baiting instrument arranges that debugging is complete, in a non-operative state, variable frequency pump 1 is in closing condition, and for being rigidly connected between jet water jet standpipe 3 and the water conveyance steel tube 2 of the section of connection, water conveyance steel tube 2 is connected for being rigidly connected or flexibly connect with the variable frequency pump 1 in ballast tank.
After boat for collection and transportation of fish arrives collection fish region, start the pump control unit on ship, the frequency transformer of regulable control variable frequency pump 1 flow, thus increase gradually or reduce pump capacity, pump capacity is adjusted to the setting flow simulated with fluid calculation software in advance to reach required jet velocity.
When Ji Yucangdao and jet pipe 3 flow velocity are close to required flow rate, stop regulating variable frequency pump 1, reserve observation of enough time fluctuations in discharge, increase and decrease according to flow is finely tuned again, until pump capacity no longer includes considerable change, the shoal of fish is made to sense close to fish inlet 5 after preference current, by catching up with, in collection fish hold road, the fish-collecting box 7 that the shoal of fish caught up with by fish corral 8, fish is transported to point of destination thereupon, completes transporting something containerized fish process.
Different fish are to waterpower factor: mainly contain flow velocity, current gradient, turbulent fluctuation and shearing force, and induction behavior is different, and the fluid layer of different fish lives and the depth of water are also not quite similar, and the different depth of water has different waterpower factor values. The structure and the size size that adjust this device can realize the adjustment to waterpower factor, thus realize the attracting action to particular types fish. So being only aware of the kind of fish, the depth of water, waterpower factor value and work object, the adjustment water jet standpipe attracting structure of object and size just can be had to accord with the situation changing waterpower factor value to correspond to actual needs.
Above-described embodiment is used for explaining explanation the utility model; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment made by the utility model and change, all fall into protection domain of the present utility model.
