Description

Automatic sewage discharge device at the bottom of the pot-shaped bottom prawn breeding pond

technical field

The utility model belongs to the technical field of sewage discharge in culture ponds, in particular to an automatic sewage discharge device at the bottom of a pot-shaped bottom prawn culture pond.

Background technique

Taking a medium-sized shrimp farm with 600 cement ponds of 7m×7m as an example, it takes 6-8 workers to spend 2-3 hours a day to pull out the sewage pipes of the breeding ponds or open the drain valves to discharge the sewage, and then enter the water , and control the water level to meet the predetermined depth. Especially in the hot summer, workers have to manually operate in greenhouses where the temperature reaches 40°C or even above 50°C every day. The labor intensity is very high and the efficiency is low. Moreover, due to the small number of people in the pond, excessive drainage will occasionally occur. After adding a large amount of new water, the physical environment of the breeding pond will change suddenly, resulting in a stress response to the shrimp and even disease and death, causing unnecessary losses. In addition, the current aquaculture mode cannot achieve effective bottom sewage aquaculture while controlling the water level.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic sewage discharge device at the bottom of the prawn culture pond with a pot-shaped bottom, which can realize the automatic and zero-energy discharge of the bottom sewage of the culture pond, can maintain the water level of the culture pond while discharging sewage, and can use The device controls the water level at a set height to realize flowing water farming with automatic sewage discharge.

The technical scheme adopted by the utility model to solve the technical problem is to provide a pot-shaped bottom prawn culture pond bottom automatic sewage discharge device, including an outer sleeve, an inner sleeve and a water inlet screen, and the inner sleeve is installed on the bottom of the culture pond. The bottom is drawn out of the pond, the height of the inner sleeve inside the culture pond matches the depth of the culture water, the outer sleeve is set outside the inner sleeve and the height is higher than the inner sleeve, and the outer sleeve is connected to the inner sleeve. A water flow channel is formed between the inner sleeves, and the bottom of the outer sleeve is provided with a water inlet screen for side water inlet.

As a preferred embodiment of the present invention, the water inlet screen is a cylindrical cavity structure, and a circular hole with a diameter larger than the outer diameter of the inner sleeve is opened in the middle of the water inlet screen. The water inlet screen is provided with a water inlet hole on the side of the water inlet screen.

As a further improvement to the above-mentioned embodiment, the upper end surface of the water inlet screen is provided with a connection groove for the outer casing.

As a further improvement to the above embodiment, the water inlet holes are distributed in a matrix along the side of the water inlet screen.

As a further improvement to the above embodiment, the diameter of the water inlet hole is 2-3 mm.

Beneficial effect

The utility model uses the height difference between the outer casing and the inner casing to generate a liquid level difference in the water body, thereby producing the effect of automatic sewage discharge at the bottom of the pot-shaped breeding pond, zero energy consumption, and the setting height of the inner casing A stable breeding water depth is ensured. Therefore, the utility model can achieve sewage discharge and maintain the water depth of the breeding pond while entering the water, which can greatly reduce the labor intensity and save labor costs. At the same time, the device can also be used to control the water level at the set Height, to achieve automatic sewage aquaculture.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

A bottom automatic sewage discharge device of a pot-shaped bottom prawn culture pond as shown in FIG. 1 includes an outer casing 2 , an inner casing 3 and an inlet screen 4 .

The internal diameter of the inner sleeve pipe is 10cm, which is installed on the bottom of the culture pond 1 and leads out of the pond. The height of the inner sleeve pipe 3 inside the culture pond 1 is 80cm, which matches the depth of the culture water. The outer casing 2 has an inner diameter of 15 cm and a height of 130 cm, and is sheathed outside the inner casing 3 , forming a water flow channel between the outer casing 2 and the inner casing 3 .

The bottom of the outer casing 2 is provided with a water inlet screen 4 for side water inlet. The water inlet screen 4 is a cylindrical cavity structure, the side is 5 cm high, and a round hole with a diameter larger than the outer diameter of the inner sleeve 3 is opened in the middle, and the inner sleeve 3 passes through the round hole, and the side of the water inlet screen 4 is provided with an inlet. The water holes 5 and the water inlet holes 5 are distributed in a matrix along the side of the water inlet screen 4, and the diameter of the water inlet holes 5 is 2-3mm. The upper end surface of the water inlet screen 4 is provided with a connection groove 6 , and the outer casing 2 is installed above the water inlet screen 4 through the connection groove 6 .

The automatic sewage discharge device at the bottom of the pot-shaped bottom prawn culture pond uses the height difference between the outer casing 2 and the inner casing 3 and uses water to generate a liquid level difference in the water body, thereby producing the effect of automatic sewage discharge at the bottom of the pot-shaped culture pond. Zero energy consumption, and the setting height of the inner sleeve 3 ensures a stable depth of aquaculture water, therefore, it is possible to realize sewage and flowing water aquaculture at the bottom of the aquaculture pond, which can greatly reduce labor intensity and save labor costs.
