Description

A controllable drainage device for nursery ponds

technical field

The utility model relates to the technical field of aquaculture equipment, in particular to a controllable drainage device for nursery ponds.

Background technique

In the aquaculture system, residual bait that has not been eaten by fish, fish excrement, aging and dead animal and plant residues, dust and sediment, etc. are likely to affect water quality, cause pollution, seriously affect the water environment, and are not conducive to the healthy growth of cultured animals . Therefore, the water in the nursery pond needs to be discharged and updated frequently. Existing drainage devices mainly rely on siphons to remove sewage. In view of the complex structure, troublesome operation and high cost of existing siphon devices, most farmers currently use hoses to siphon drainage. This siphon method not only Time-consuming and labor-intensive, and when encountering granular dirt adhering to the pool wall or bottom, it is difficult to remove it only by hose siphon, so the water in the aquaculture pool cannot be replaced in time, resulting in the deterioration of the water quality in the pool.

Utility model content

The purpose of this utility model is to provide a controllable drainage device for seedling ponds, which overcomes the defects of existing seedling pond drainage devices such as complex structure, troublesome operation, increased breeding costs, time-consuming and labor-intensive hose siphoning, and poor effect. The structure is simple, the operation is convenient, the displacement is controllable, time-saving and labor-saving, the water in the breeding pond can be replaced in time, and the controllable drainage device that ensures good water quality.

In order to achieve the above-mentioned purpose, the utility model adopts the following specific technical solutions: the controllable drainage device for the seedling pond, including the low-end water pipe, the high-end water pipe connected to the low-end water pipe, and the mouth of the low-end water pipe. The protective cover at the top of the high-end drain pipe and the low-end suction pipe is provided with an air control switch at the top; the bottom of the low-end suction pipe is bent upwards to reduce the pumping pressure; The water control switch that can control the drainage speed and drainage volume, the bottom of the high-end drainage pipe bends upwards, and is connected with the water injection pipe.

The utility model realizes the controllable drainage of the seedling pool through the following steps. When the seedling pool needs to be changed, the protective cover is put into the pool, and the low-end suction pipe is placed in the protective cover, and connected at the bottom connection of the high-end drainage pipe. A water injection pipe with the same length as the high-end drainage pipe, and turn on the water control switch and the air control switch to add water to the water injection pipe. Separated from the connection of the high-end drain pipe, the nursery pool can be automatically pumped by the effect of air pressure. The water control switch can control the drainage speed and volume. Turn on the air control switch, and the drainage will stop.

Compared with the existing drainage device, the utility model is characterized by simple structure, convenient operation, controllable drainage, time-saving and labor-saving, timely replacement of water in the breeding pond, ensuring good water quality, and ensuring the output and quality of breeding.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed ways

    In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.   

As shown in Figure 1, the controllable drainage device used for nursery ponds includes a low-end suction pipe 1, a high-end drainage pipe 2 connected to the low-end suction pipe 1, and a protective cover 3 covering the mouth of the low-end suction pipe 1 , the protective cover 3 prevents the fry and the waste water from being sucked away when pumping, and the top of the connection between the high-end drain pipe 2 and the low-end pumping pipe 1 is provided with an air control switch 4; the bottom of the low-end pumping pipe 1 is bent upwards to reduce the pumping pressure The 3/4 height of the high-end drainage pipe is provided with a water control switch 5 that can control the drainage speed and displacement, and the bottom of the high-end drainage pipe 2 is bent upwards to connect the water injection pipe 6. When the nursery pond needs to change water, the protective The cover 3 is put into the pool, the low-end water pumping pipe 1 is placed in the protective cover 3, a water injection pipe 6 with the same length as the high-end drain pipe 2 is connected to the bottom connection of the high-end drain pipe 2, and the water control switch 5 and the water control switch 5 are turned on. Air switch 4, add water to the water injection pipe 6, stop adding water when the water level exceeds the height of the low-end pumping pipe 1, then turn off the air control switch 4, separate the water injection pipe 6 from the connection of the high-end drain pipe 2, and then use the air pressure The effect of the nursery pool is automatically pumped, the water control switch 5 can control the drainage speed and the displacement, and the air control switch 4 is opened, and the drainage stops.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modification or equivalent replacement of the technical solutions without departing from the spirit and scope of the technical solutions of the present utility model, all of which shall be covered by the scope of the claims of the present utility model.
