Description

An automatic sewage discharge structure for intensive aquaculture

technical field

The utility model relates to aquatic product cultivation, in particular to a sewage discharge device for intensive aquaculture.

Background technique

Aquaculture is an important part of agricultural production. With the development of my country's economy and society, the scale of aquaculture continues to expand. Industrial intensive aquaculture has been widely promoted and applied due to its small land occupation, low water consumption and high output. Higher requirements are put forward for its sewage system and breeding environment. In the actual breeding process, it is inconvenient to remove the feces, residual bait and other dirt in the breeding pond. If it is not removed in time, it will directly affect the production of aquatic products.

At present, most of these dirt are removed manually or by machine. Although it can be removed, the labor load of manual removal is increased, and the effect is not good. The structure of the cleaning equipment is complicated, the energy consumption is high, the service life is low, and the production cost is relatively high. high.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic sewage discharge device for intensive aquaculture with simple structure, convenient use and low cost.

The utility model is achieved through the following technical solutions:

The utility model comprises a breeding pond, a sewage isolation net, and a water level limiter. The sewage isolation net is fixed on the lower part of the culture pond, and one side of the bottom of the culture pond has a water outlet, and the water outlet is movably connected with the water level limiter.

The bottom of the culture pond is designed as an inclined plane.

The inclination angle of the slope is 5-15 degrees.

The sewage net is a plastic net.

The sewage net is fixed at 1/3-1/5 of the culture pond from the bottom.

The water level limiter includes a sewage pipe, an elbow, and a water level adjustment bayonet. The lower part of the sewage pipe is movably connected to the drain at the bottom of the culture pond through the elbow. Snap on the water level adjustment bayonet.

The elbow is a right-angle elbow.

There are 2-10 bayonets for adjusting the water level.

The inclination angle of the water level adjustment bayonet is 20-60 degrees.

Put the aquatic products on the top of the sewage isolation net of the aquaculture pond, and the feces, residual bait and other dirt generated during the aquaculture process enter the bottom of the aquaculture pond through the sewage isolation net, and the sewage pipe of the water level limiter is vertically upward. The upper part of the sewage pipe is moved, and the position of the sewage pipe is fixed through the water level adjustment bayonet, so that not only the water level of the aquaculture pond can be controlled, but also the sewage at the bottom of the aquaculture pond can be removed through the sewage pipe of the water level limiter, and no energy is required. , to achieve automatic sewage.

Compared with the prior art, the utility model has the following advantages:

1. The utility model is simple in structure, easy to use, and saves production cost.

2. The utility model has better sewage discharge effect, maintains the breeding environment, and improves production efficiency.

3. It does not need any energy, directly discharges sewage at any time, has a long service life and low cost.

specific implementation plan

Embodiment 1: below in conjunction with accompanying drawing 1, Fig. 2 the utility model is further described:

The utility model comprises a culture pond 1, a sewage isolation net 3, and a water level limiter. The bottom of the culture pond 1 is designed as an inclined plane 2 with an inclination angle of 5-15 degrees, and the inclination angle of the present embodiment is 10 degrees. Sewage isolation net 3 is fixed on the 1/4 place from the bottom of the culture pond, and the sewage net is a plastic net, and can also be meshes such as steel wire or barbed wire. The water level limiter includes a sewage pipe 8, a right-angle elbow 7, and a water level adjustment bayonet 5. The bottom of the sewage pipe 8 is flexibly connected to the drain outlet 9 at the bottom of the culture pond through the right-angle elbow 7. A water level adjustment bayonet 5 is fixed above, and the top of the sewage pipe 8 can be stuck on the water level adjustment bayonet 5 . There are five fixing bayonets 5 for the water level adjustment, and the inclination angle is 40 degrees. The water level adjustment bayonet 5 is directly opened on the outer side wall 6 of the culture pond 1 to form a mouth that can place the sewage pipe 8, and also can fix the angle steel on the outer side wall 6 of the culture pond 1, and the design on the angle steel can fix the sewage pipe 8 Location.

Aquatic product is put into culture pond blowdown isolation net 3 tops, below the water level line 4, and when blowdown pipe 8 was vertical with culture pond outlet 9, blowdown pipe 8 was identical with water level line 4 heights. During use, the upper part of the sewage pipe 8 is moved on the water level adjustment bayonet 5, and the position of the sewage pipe 8 is fixed by the water level adjustment bayonet 5, so as to control the water level of the culture pond, and the circulation of water can also be used. The dirt at the bottom of the culture pond 1 is removed from the culture pond 1 through the sewage pipe 8 .
