Abstract

The utility model relates to an aquaculture device, in particular to a fry culture pond blow-down system which comprises a pot-shaped aquaculture pond body, a blow-down outlet, a blow-down pipe column and a water return overflow pipe. The blow-down outlet is arranged at the center of the bottom of the aquaculture pond body, the blow-down pipe column provided with a plurality of blow-down holes is arranged at the blow-down outlet, a screen mesh is arranged at each blow-down hole of the blow-down pipe column, a blow-down pipe is arranged between the blow-down outlet and the water return overflow pipe, an overflow port is arranged on the upper side of the water return overflow pipe, and a blow-down pond is arranged below an outlet of the overflow port. Sewage is conveniently collected as the bottom of the aquaculture pond body is pot-shaped, the sewage is discharged by the blow-down pipe column arranged at the blow-down outlet at the center of the bottom of the aquaculture pond body through the blow-down holes formed in the blow-down pipe column, and cultured aquatic products are prevented from entering the blow-down holes as the screen mesh is arranged at each blow-down hole. By the aid of the columnar structure with the multiple blow-down holes, the sewage can be effectively prevented from blocking the blow-down holes, and sewage discharge is facilitated.

Description

A kind of rearing pond drainage

Technical field

The utility model relates to used for aquiculture equipment, relates in particular to a kind of rearing pond drainage.

Background technology

Aquaculture is the activity in production of artificial control breeding down, cultivation and results aquatic animals and plants.Generally comprise the overall process of under the artificial feeding management, forming aquatic products from seed.Broadly also can comprise aquatic resources propagation.Aquaculture has modes such as extensive cultivation, intensive culture and high density intensive culture.Extensive cultivation is to throw in seed in medium and small natural waters, forms aquatic products by natural bait fully, breeds fish as lake and reservoir and supports shellfish etc. with the shallow sea.Intensive culture is to form aquatic products with bait throwing in, fertilizing method in less water body, as aqiuculrue, fish culture in net pen and enclosure culture, net enclosure culture etc.Methods such as flowing water, temperature control, oxygenation and the high-quality bait of throwing something and feeding are adopted in the high density intensive culture, carry out high-density breeding in little water body, thereby obtain high yield, as flowing water high-density fish culture, shrimp etc.

Culture and to discharge culturing the backwater that has sewage in the pond high density intensive culture fry, and will culture and inject new water in the pond, reached the purpose of water saving and maintenance feeding environment, the excretion machine of existing aquaculture pond is that sewage stops up sewage draining exit easily, is unfavorable for the sewage discharge.

The utility model content

Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of rearing pond drainage that sewage is discharged that is beneficial to is provided.

The utility model is to be achieved by the following technical programs:

A kind of rearing pond drainage, the aquaculture pond pond body that comprises pot type, be located at the sewage draining exit that aquaculture pond pond body bottom center is established, be located at the blowdown tubing string that has a plurality of mudholes and backwater overflow pipe on the sewage draining exit, the mudhole of described blowdown tubing string is provided with screen cloth, be provided with blow-off pipe between described sewage draining exit and the backwater overflow pipe, described backwater overflow pipe upside is provided with gap, and described gap outlet has pollution discharge pond.

Described mudhole becomes 30 degree helixes to arrange at the backwater overflow pipe.

The beneficial effects of the utility model are:

Because being convenient to sewage for the pot type at the bottom of the body pond, aquaculture pond pond converges, be located at blowdown tubing string on the sewage draining exit of bottom center by mudhole provided thereon, sewage is discharged, mudhole is provided with screen cloth, prevent from culturing aquatic products and enter mudhole, many mudholes of this kind pillar structure can prevent effectively that sewage from stopping up mudhole, is beneficial to sewage and discharges.

Description of drawings

Fig. 1 is main TV structure schematic diagram of the present utility model.

Among the figure: 1. aquaculture pond pond body, 2. blowdown tubing string, 3. mudhole, 4. blow-off pipe, 5. backwater overflow pipe, 6. pollution discharge pond, the 7. water surface, 8. gap.

Embodiment

In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.

As shown in the figure, the utility model comprises the aquaculture pond pond body 1 of pot type, be located at the sewage draining exit that aquaculture pond pond body bottom center is established, be located at the blowdown tubing string 2 that has a plurality of mudholes 3 and backwater overflow pipe 5 on the sewage draining exit, the mudhole of described blowdown tubing string is provided with screen cloth, be provided with blow-off pipe 4 between described sewage draining exit and the backwater overflow pipe, described backwater overflow pipe upside is provided with gap 8, and described gap outlet has pollution discharge pond 6.

Described mudhole becomes 30 degree helixes to arrange at the backwater overflow pipe.The interior pressure of aquaculture pond can be added evenly, be conducive to the fry growth.

During work, sewage enters the backwater overflow pipe from mudhole, and backwater overflow pipe and aquaculture pond pond body form linker, and when injecting new water in the pond to culturing, when the water surface 7 was higher than the gap of backwater overflow pipe, water overflowed from gap and falls in the pollution discharge pond.

The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims
