Abstract
A river blocking fish collecting device comprises at least one fish collector and at least one V-shaped fish guiding fence, the fish collector is provided with a fish collecting box, the V-shaped fish guiding fence is arranged close to the left side and the right side of an inlet of the fish collector, and the V-shaped fish guiding fence is connected with the inlet and the river bank. According to the river blocking fish collecting device, through the fish guiding mode in a river, full-river-reach high-proportion collecting of fishes which swim upstream and downstream is achieved, and damage of fishes is avoided.
Description
Technical field
A kind of barrage fish-aggregating device of the utility model.
Background technology
The migration of fish is a kind of motion of the conversion habitat that has certain orientation, certain distance and certain hour.This motion normally cluster, regular, have periodically, and there is hereditary characteristic.According to the object of migration, migration can be divided into feeding migration, overwintering migration and egg-laying migration.Barrage is built a dam, and meeting is blocked or the migration of retardation fish, causes forfeiture or the change of habitat, causes minimizing or even the extinction of fish.Under specific situation, as: river upstream and downstream is built dam all, need to will in river, trace back migration or descending fish catch and transfer to the specific bodies of water.Current fish not damaged collection method is more common in netting gear, as: cage, also have fishing gathering device for collecting fish, but there is difficult fixing or volume limitation less than normal in netting gear, there is the limitation with respect to river course small volume in fishing gathering device, uses separately fish-gathering effect all on the low side.In river, how full section fish gathering, realizes catching at high proportion of upstream and downstream fish, requires study.
Summary of the invention
The purpose of this utility model is to provide a kind of barrage fish-aggregating device, for collecting the upper and lower fish individual moving about in river.This device carries out efficient capture by M type, full section barrage fish-aggregating device design double V-shaped or Z-type to the fish of up-downgoing in river.
The technical scheme that the utility model is taked is: a kind of barrage fish-aggregating device, comprise that at least one fishing gathering device, at least one V-type lead fish corral, described fishing gathering device is provided with fish-collecting box, and left side, the right side of the import of close fishing gathering device are provided with V-type and lead fish corral, and V-type is led fish corral and connected described import and riverbank.
It is barrier net or grid that described V-type is led fish corral.
Multiple V-types are led fish corral and are connected and composed M type, double V-shaped or Z-type.
The angle α that described V-type is led fish corral and riverbank is less than 45 °.
A kind of barrage fish-aggregating device of the utility model, beneficial effect is as follows:
The fish of realizing the up-downgoing of collecting at high proportion in full cross section, section in river by leading the mode of fish, avoid the damage of fish.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
Fig. 3 is the utility model embodiment 3 structural representations.
Wherein "---→ " direction is water (flow) direction.
Embodiment
As shown in Fig. 1 ~ Fig. 3, a kind of barrage fish-aggregating device, comprises that at least one fishing gathering device 1, at least one V-type lead fish corral 2, and described fishing gathering device 1 is provided with fish-collecting box 1.2, left side, the right side of the import 1.1 of close fishing gathering device 1 are provided with V-type and lead fish corral 2, and V-type is led fish corral 2 and connected described import 1.1 and riverbank.Described V-type is led fish corral 2 for barrier net or grid, the fish that upwards move about or move about downwards in order to interception and induction, and the while can discharge by extracting grid out the rubbish of upstream.Described V-type is led fish corral 2 and is less than 45 ° with the angle α on riverbank.Fishing gathering device 1 downstream is respectively equipped with the V-type of joining with the left and right bank in river course and leads fish corral 2, and supporting measure for fish crossing traces back or descending fish with directional induction.

Embodiment 2:
Double V-shaped barrage fish collection system:
Comprise that two V-types lead 2,1 fishing gathering device 1 of fish corral.The first V-type leads that fish corral one end is connected with left bank, the other end is connected with right bank, and V-type is led fish corral end and connected first fishing gathering device one end;
The second V-type leads that fish corral one end is connected with left bank, the other end is connected with right bank, and V-type is led fish corral end and connected the second fishing gathering device other end.
Embodiment 3:
Z-type barrage fish collection system:
Comprise that two V-types lead 2,2 fishing gathering devices 1 of fish corral.The first V-type leads that fish corral one end is connected with left bank, V-type leads that fish corral end connects the first fishing gathering device, the other end connects the second fishing gathering device;
The second V-type is led fish corral one end and is connected the first fishing gathering device, V-type and lead that fish corral end connects the second fishing gathering device, the second V-type is led the fish corral other end and connected right bank.
