Zero-energy automatic sewage disposal unit for prawn breeding pond

Abstract

The invention discloses a zero-energy automatic sewage disposal unit for a prawn breeding pond. The zero-energy automatic sewage disposal unit for the prawn breeding pond comprises the breeding pond,wherein a sewage outlet is formed in the bottom of the breeding pond; a turbine is arranged above the sewage outlet; a turbine cover is arranged above the turbine; a connecting shaft is arranged at the upper end of the turbine, penetrates through the turbine cover and is movably connected to the inside of an anti-escaping cover; connecting rods are arranged on two sides of the connecting shaft; and a scraper blade is arranged on each connecting rod. The sewage outlet is formed in the bottom of the breeding pond, thus, breeding sewage is convenient to drain, the turbine is arranged above the sewage outlet, during draining of sewage, the turbine is driven by power of water flow, then the connecting rods on two sides of the connecting shaft are driven, a scraper blade arranged on each connecting rod drives the water flow, thus, ring flow is formed on the periphery of the center of the pond, finally, dirt is driven to be collected to the center of the pond, and is discharged out of the pond, by the turbine cover arranged above the turbine, influences of the water flow to the portion over the turbine can be reduced, and thus, the rotating speed of the turbine is increased. The device issimple in structure, convenient to operate and suitable for being popularized on a large scale.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an automatic decontamination device for zero-energy prawn culture ponds. Background technique [0002] The deterioration of water quality in aquaculture ponds is often the cause of disease occurrence, and to a certain extent becomes the key factor for the success of aquaculture. Therefore, in aquaculture, it is necessary to remove various pollutants in the aquaculture water body in a timely and efficient manner, such as residual bait, aquatic animal excrement, aquatic animal carcasses, etc., so as to avoid the pollution of these pollutants to the aquaculture water body and keep the aquaculture water body good water quality. When manual sewage is discharged, it is necessary to pull out the pipe to discharge sewage, which is troublesome to operate, and the seedlings of aquatic products will be discharged during sewage discharge, which reduces the output of aquatic products.

Problems solved by technology

At present, the water wheel aerator is basically used to form a circulation, so that the dirt is collected to the center of the pool, but there is a problem with this method, that is, the speed around the center of the pool is very low, causing the dirt to gather near the center of the pool. But it cannot be discharged smoothly, so it is necessary to design a device to increase the flow rate near the center of the pool, so as to drive the dirt to the center of the pool
