Abstract

The utility model relates to a drainage device of a long-running water culture pond, belonging to the field of aquaculture equipment, which comprises a thick drainage pipe of a thin drainage pipe and a drain outlet; the drain in breed pond is inserted to the one end of thin drain pipe, and the height of thin drain pipe keeps level with the breed water level basically, and thick drain pipe diameter is greater than thin drain pipe, and thick drain pipe cover is in the thin drain pipe outside, and thick drain pipe is higher than thin drain pipe, and thick drain pipe has the hole of permeating water near on the pipe wall of breeding pond drain one end. The operation principle of this device is that breed pond lower floor's water flows in the space between two rows of water pipes through the hole of permeating water of thick drain pipe bottom, and the water level between two rows of water pipes risees, and the water that risees gets into the drain from the mouth of pipe of thin drain pipe, then from the drain drainage to the water level that maintains the breed pond is unchangeable, discharges and breeds pond lower floor's water. Use the utility model discloses when breeding the drainage, can discharge and breed the higher lower floor's water of ammonia nitrogen and nitrite content in the pond, keep the better well upper strata water of water quality, improve and breed pond quality of water, it is fresh to maintain quality of water.

Description

Drainage device of long-running water culture pond

Technical Field

The invention belongs to the field of aquaculture, and particularly relates to a drainage device of a long-running water culture pond.

Background

In the aquaculture process, the long-flowing water culture is often needed, the mode of carrying out the long-flowing culture in prior art with the quality of water fresh of maintaining the breed pond does, central drain port department at the breed pond sets up a drain pipe, the height of drain pipe is kept level with the breed water level, when the inlet tube was intake, breed pond water level risees, the mouth of pipe entering drain of the water drain pipe of rising water, thereby maintain the water level of breed pond unchangeable, but this kind of long-flowing water mode, the upper strata water of discharged water for breeding the pond, and the general quality of water of upper strata is better in breeding the pond, the lower floor water of breed pond is because incomplete bait, faecal pollution, ammonia nitrogen and nitrite content are higher in the water.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a drainage device in long-running water culture pond, the device can be when the long-running water is bred, and the lower floor's water in culture pond is bred to the priority discharge to it is fresh to maintain quality of water.

The utility model discloses a realize through following technical scheme:

a drainage device of a long-running water culture pond comprises a thick drainage pipe of a thin drainage pipe and a drain outlet; the one end of thin drain pipe is inserted in the drain of breeding the pond, and the height of thin drain pipe keeps level with breeding the water level, and thick drain pipe diameter is greater than thin drain pipe, and thick drain pipe cover is in the thin drain pipe outside, and thick drain pipe is higher than thin drain pipe, has the hole of permeating water on the pipe wall that thick drain pipe is close to breeding pond drain one end.

The operation principle of this device is that breed pond lower floor's water flows in the space between two rows of water pipes through the hole of permeating water of thick drain pipe bottom, and the water level between two rows of water pipes risees, and the water that risees gets into the drain from the mouth of pipe of thin drain pipe, then from the drain drainage to the water level that maintains the breed pond is unchangeable, discharges and breeds pond lower floor's water.

The utility model has the advantages of compared with the prior art:

use the utility model discloses when breeding the drainage, can discharge and breed the higher lower floor's water of ammonia nitrogen and nitrite content in the pond, keep the better well upper strata water of water quality, improve and breed pond quality of water, it is fresh to maintain quality of water.

Drawings

Fig. 1 is the structure schematic diagram of the utility model: 1. the water level of the culture pond is 6, and the holes are penetrated through 2, thin drain pipes 3, thick drain pipes 4, sewage outlets 5 and the water level of the culture pond.

Detailed Description

The technical solution of the present invention is further explained by the following examples. The scope of the present invention should not be limited by the embodiments in any way.

Example 1

A drainage device of a long-running water culture pond is shown in figure 1, wherein a thin drainage pipe 2, a thick drainage pipe 3 and a sewage outlet 4 are arranged in a culture pond 1; in the drain of breed pond was inserted to the one end of thin drain pipe, the height of thin drain pipe was kept level with breed pond water level 5 basically, and thick drain pipe diameter is greater than thin drain pipe, and thick drain pipe cover is in the thin drain pipe outside, and thick drain pipe is higher than thin drain pipe 5cm, has the hole of permeating water 6 on the pipe wall that thick drain pipe is close to breed pond drain one end.

Breed pond lower floor's water and flow in the space between thick drain pipe and the thin drain pipe through the hole of permeating water of thick drain pipe bottom, and the water level in the space risees, and the water that risees gets into in the thin drain pipe from the upper end mouth of pipe of thin drain pipe, then from the drain drainage to the water level that maintains the breed pond is unchangeable, discharges the lower floor's water in the breed pond.

Claims

1. A drainage device of a long-running water culture pond is characterized by comprising a thin drainage pipe, a thick drainage pipe and a sewage discharge outlet; the one end of thin drain pipe is inserted in the drain of breeding the pond, and the height of thin drain pipe keeps level with breeding the water level, and thick drain pipe diameter is greater than thin drain pipe diameter, and thick drain pipe cover is in the thin drain pipe outside, and thick drain pipe is higher than thin drain pipe, and thick drain pipe has the hole of permeating water near on the pipe wall of breeding pond drain one end.
