Flow-rate-controllable liberating pipeline

Abstract

The invention discloses a flow-rate-controllable liberating pipeline which is provided with a pipe chase, wherein the two ends of the pipe chase are opened; the inside of the pipe chase is internally provided with a baffle (which can divide the pipe chase into at least two water-stop cabins) in a movable fit mode; and the baffle is connected with a control device which can adjust the slant angle of the baffle. The pipe chase can enable a water-flow to flow along a certain direction, and along with the adjustment of the control device on the angle of the baffle, the difference between the water levels of the water-stop cabins can be changed along with the change of the angle of the baffle, therefore, through adjusting the angle of the baffle, the effects of controlling the difference between water levels and controlling the liberating speed can be achieved, and the effect of fry liberating operated in water also can be achieved. The flow-rate-controllable liberating pipeline disclosed by the invention has the advantages of being novel in structure, controllable in liberating speed, slight in damages on fish bodies and suitable for large-scale liberating.

Description

technical field [0001] The invention relates to a multiplication and release device, in particular to a flow rate-controllable discharge pipeline. Background technique [0002] In recent years, large-scale economic construction and resource development have been carried out in coastal and river basin areas, and at the same time, they have had a great impact on the ecological environment of natural waters. Fishery resource proliferation and release is to release wild fish, shrimp, crab, shellfish, etc. into natural waters where fishery resources are declining after artificial breeding, breeding, or fishing of natural seedlings, so that the natural population can be restored. recover. Years of practice have proved that the proliferation and release of fishery resources is an important and effective means to restore the amount of aquatic biological resources at present, and it should give full play to its due role. At present, there is still a big gap between the number of mu...

AI Technical Summary

Problems solved by technology

Most of the existing breeding and release methods use artificial water-carrying operations, which cannot be continuously released in large quantities, and the efficiency is low, and it is not suitable for deep release in sea areas, and is greatly affected by wind and waves.
