Multifunctional culture water drainage strobe

Abstract

The invention relates to a multifunctional culture water drainage strobe. A barrel-drain is arranged at a position outside a culture pond filled with the culture water and lower than the bottom of a drainage port of the culture pond; the drainage strobe comprises an outer sleeve arranged in the culture pond; the lower part of the outer sleeve is provided with a water through hole groove; the bottom of the culture pond inside the outer sleeve is provided with a drainage port; one end of a drainage concealed conduit arranged below the bottom of the culture pond is communicated with the culture pond through the drainage port; an inner insertion tube arranged in the outer sleeve can be inserted into or pulled out of the end of the drainage concealed conduit; a swing type water level control tube arranged in the barrel-drain can be inserted into or pulled out of the other end of the drainage concealed conduit; the water level control tube inserted into the drainage concealed conduit can swing around a connecting point between the water level control tube and the drainage concealed conduit; the top ends of the outer sleeve, the inner insertion tube and the water level control tube are all opening ends; and the top end of the inner insertion tube is lower than that of the outer sleeve. The strobe has the characteristics of automatic control of water level, good sealing performance, effective drainage of culture water at the bottom layer, timely drainage of redundant water in disaster weathers, simple and convenient construction and the like.

Description

technical field [0001] The invention relates to aquaculture, in particular to a drainage gate for aquaculture. Background technique [0002] Aquaculture is the main mode of fishery production in our country and occupies an important position in our country's fishery production. In the world, aquaculture may be the fastest growing food production sector, currently accounting for nearly half of the total food fish. Water is the material basis of aquaculture. Timely adding water, draining water, and adjusting water quality are one of the important measures to stabilize production, increase production, and improve economic benefits. [0003] The main consideration of existing drainage gates for aquaculture is drainage. It is generally used to set a plunger-type bottom gate with a retaining net on the side wall or bottom of the aquaculture tank. The bottom gate communicates with the drainage ditch through a drain pipe. The problem is: [0004] ①The depth of the aquaculture wate...

AI Technical Summary

Problems solved by technology

[0004] ①The depth of the aquaculture water body required by most aquaculture species is above 3M, and most of the bottom gates need to be manually probed with a special hook tool to the underwater non-visible operation when opening / closing the bottom gate. It is very laborious to open the bottom gate, and the opening and closing operation of the gate is cumbersome;

[0005] ② The airtightness inside the existing gate is poor, and there is water leakage;

[0006] ③ There is no barrier between the upper and lower water layers. Due to the eddy current, the clean upper layer water will also be mixed with the turbid bottom water and discharged together, and the effective discharge of aquaculture wastewater at the bottom of the pond or tank cannot be controlled;

[0007] ④ Since the opening / closing of the bottom gate requires manual operation, in daily management, the gate cannot accurately control the effective water level of the aquaculture water body by itself according to changes in the external environment;

[0008] ⑤When catastrophic weather such as heavy rainfall comes suddenly, the gate cannot control the water level by itself, and at the same time, the external conditions are bad, and the drainage valve gate cannot be manually opened to drain water in time, which will cause economic losses to farmers;
