Device for discharging pollutions at bottom and surface of culture pond and automatically collecting diseased fishes and dead fishes

Abstract

The invention discloses a device for discharging pollutions at the bottom and the surface of a culture pond and automatically collecting diseased fishes and dead fishes. The device comprises a tray, wherein the tray is provided with a tray edge and a tray surface; the device further comprises a central pollution discharging pipe; the upper end of the central pollution discharging pipe is sealed; an opening at the lower end of the central pollution discharging pipe is communicated with a pollution discharging opening in the bottom of the culture pond; the top surface of the tray surface is at least connected with a fish intercepting pipe with water draining holes in the side surface; the height of the fish intercepting pipe is larger than that of the tray edge; the bottom surface of the tray surface corresponding to the fish intercepting pipe is connected with a backflow pipe which is communicated with the fish intercepting pipe and connected with the central pollution discharging pipe; at least one water inlet hole is also formed in the tray surface of the tray; a water blocking piece matched with the water inlet hole is detachably connected to the water inlet; and the bottom surface of the tray corresponding to the water inlet is connected with a pollution absorbing pipe communicated with the water inlet. Compared with the prior art, the device has the advantages as follows: the pollutions at the surface and the bottom of the culture pond can be rapidly discharged out; and the diseased fishes and the dead fishes can be automatically collected during discharging the pollutions, so that the spread of pathogens and pollutions of the dead fishes to the environment are blocked.

Description

technical field [0001] The invention relates to a device for automatically collecting sewage from the bottom and surface of a culture pond, and automatically collecting diseased and dead fish. Background technique [0002] It is always a difficult problem in the recirculating aquaculture system to quickly discharge the sewage and realize the solid-liquid separation in the aquaculture pond. At present, the method to solve this problem mainly depends on the inflow of water along the edge of the pond to cause the water circulation of the culture pond to gather the sewage in the center of the bottom of the pond, and use the hydraulic pressure to discharge the sewage from the central sewage hole. But the deficiency of this method is that the dirt that sinks in the bottom of the culture pond can only be discharged from the culture pond, and the organic matter floating on the water surface stays in the culture pond and pollutes the culture water body all the time. Sick fish or fre...

But the deficiency of this method is that only the dirt that sinks in the bottom of the culture pond can be discharged from the culture pond, and the organic matter floating on the water surface is always stranded in the culture pond to pollute the culture water body

Sick fish or freshly dead fish will also gather in the center of the bottom of the aquaculture pond under the action of the water cycle, and it is difficult to be found. If they are not removed from the aquaculture pond in time, they will rot and deteriorate and pollute the water body, directly or indirectly affecting the health of other fish. healthy

At present, there is no special device to collect sick fish and dead fish, mainly relying on manual salvage
