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

Embodiment 1

[0026] Such as Figure 1-6 Shown, the scheme that the present invention takes for realizing the above object is: a kind of zero-energy consumption prawn cultivation pond automatic cleaning device, comprises cultivation pond 6, and the bottom of cultivation pond 6 is provided with blowdown outlet 25, and the top of blowdown outlet 25 is provided with turbine 1. A turbine cover 4 is provided above the turbine 1, and a connecting shaft 7 is provided on the upper end of the turbine 1 to pass through the turbine cover 4 to flexibly connect to the inside of the escape cover 5. A connecting rod 8 is provided on both sides of the connecting shaft 7, and a scraper is arranged on the connecting rod 8. slice 9. The sewage outlet set at the bottom of the breeding pond is convenient for the discharge of breeding sewage. There is a turbine above the sewage outlet. When the sewage is discharged, the power of the water flow drives the turbine, and then drives the connecting rods on both sides...

Embodiment 2

[0033] Such as Figure 7-8 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: the surface of the turbine cover 4 is evenly distributed with water filter sheets 14 with curved inner surfaces, and the upper and lower ends of the water filter sheet 14 are connected with inwardly folded Splitter 16. The evenly distributed inner surface of the turbine cover is a curved water filter, which can make the water flowing into the turbine cover generate a larger and faster water flow vortex when it follows the curved inner surface of the water filter. The inwardly folded splitter connected to the upper and lower ends of the water sheet can generate multiple streams of water flowing into the turbine cover and re-converge in the turbine cover, making the rotational force generated by the water flow stronger and larger, greatly improving the internal The speed of the turbine blades speeds up the cleaning process.

[0034] Turbine blades 18 are evenly dist...

Embodiment 3

[0037] The working principle of the zero-energy prawn breeding pond automatic cleaning device of the present invention is as follows: open the sewage outlet 25 to discharge sewage, and under the impact of the water flow, the turbine blade 18 is rotated under the impact of the water flow, thereby driving the connection with the turbine 1 The connecting shaft 7 rotates, so that the connecting rod 8 and the scraper 9 make a circular motion at the bottom of the culture pond 6, and drive the water at the bottom of the pond near the center of the pond to flow to form a circulation, thereby collecting the dirt to the center of the pond, and at the bottom of the water pump 3 Under the action, the sewage in the center of the pool is discharged from the sewage pipe 2.

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. [0003] Th...
