Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a three-section automatic sewage pipe for circulating aquaculture. Background Art

[0002] In conventional aquaculture ponds, the dead and sick fish are identified by the aquaculture staff by observing the activity of the fish school. Since the aquaculture water in the recirculating aquaculture system is not crystal clear, it is difficult to directly observe the sick and dead fish at the bottom of the pond in deep water. The dead fish can only be directly observed after a period of time and then separated from the fish school by salvaging. This increases the labor intensity of the aquaculture staff, and the risk of cross-infection among the fish school is greatly increased if the dead fish are not salvaged in time and are not salvaged until they float to the surface.

[0003] In addition, in conventional aquaculture ponds, the method of removing floating objects such as oil film and foam from the water surface is either to make a central pipe full of holes from top to bottom; or to make holes on the side of the pool wall to remove floating objects on the water surface; although the method of making a central pipe full of holes from top to bottom can remove floating objects, the flow rate is large due to the huge number of holes, and the flow rate is small when the pipe cross section is fixed. The water flow has no adsorption capacity for floating objects on the surface, and the floating objects need to fall into the holes to be discharged, so it takes a long time to be discharged cleanly; the method of discharging from the side, due to the centrifugal force of the water flow, most of the floating objects move to the center of the pool body, and only a small part of the floating objects on the side can be discharged. Therefore, according to the different characteristics of impurities, a central cannula that can match the aquaculture pond to accurately and quickly remove various impurities is also a necessary key point in factory-scale recirculating water aquaculture. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] To this end, one purpose of the utility model is to provide a three-section automatic sewage pipe for circulating aquaculture to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a three-stage automatic sewage pipe for circulating aquaculture, comprising a chassis insert pipe, a porous groove, and a suspension pipe, wherein the porous groove is sleeved on the outside of the chassis insert pipe, and the suspension pipe is sleeved on the inside of the chassis insert pipe;

[0007] The chassis insert is a vertical through structure, and a plurality of fish discharge ports are provided on the chassis insert, and a plurality of track ports are provided on the chassis insert;

[0008] The porous groove is provided with a plurality of sewage outlets, a track pipe is fixedly connected to the porous groove near the bottom, the track pipe is movably connected to the track outlet, a traction rope is fixedly connected to the inner side of the porous groove, and a fixed rotating wheel is movably connected to the outer surface of the traction rope;

[0009] Both sides of the top of the suspension tube are fixedly connected with foam floating tubes, and the top end of the suspension tube is fixedly connected with a surface water drainage port, and the surface water drainage port is composed of a plurality of small holes.

[0010] Preferably, any of the above schemes is that the chassis insert tube and the porous groove are made of stainless steel, and the height of the porous groove on the chassis insert tube is adjustable.

[0011] Adopting the above technical solution: this three-section automatic sewage pipe is composed of a chassis insert pipe, a porous groove, and a suspended pipe from bottom to top, and the surface water drainage outlet is composed of several small holes to prevent the escape of the cultured species.

[0012] Preferably, any of the above schemes is that the opening and closing of the fish discharge port is controlled by a porous groove, and at least four fish discharge ports are provided.

[0013] The above technical scheme is adopted: during the breeding process in the breeding pond, the porous trough is sleeved on the outside of the chassis insert pipe, and the suspension pipe is sleeved on the inside of the chassis insert pipe, with the suspension pipe on the top and the porous trough on the bottom; due to the buoyancy of the water body, the foam float tube on the suspension pipe floats on the water surface, ensuring that the surface water drainage outlet can be flush with the water surface under any liquid level conditions, and the bottom is sleeved on the inside of the chassis insert pipe to ensure that the suspension pipe does not deviate from the position; during the breeding process, the dirt at the bottom of the water body is discharged from the chassis, and some semi-floating dirt sinks to the bottom and enters the porous trough drainage outlet, and then is discharged to the outside of the breeding pond through the chassis main drainage pipe; floating objects such as oil film and foam on the surface of the water body pass through the surface water drainage outlet and are discharged from the breeding pond chassis main drainage pipe.

[0014] During the breeding process, the breeders pull the traction rope from time to time. During the pulling process, the fixed wheel can ensure that the traction rope only exerts an upward pulling force on the porous trough when it is pulled on the side wall of the breeding pond, causing the porous trough to move up and down intermittently. After moving upward, sick fish or dead fish are discharged to the outside of the breeding pond through the fish discharge port and collected by the drainage pipe, thereby achieving the purpose of discharging sick and dead fish without affecting the normal operation of the system.

[0015] Preferably, any of the above schemes is that the track opening is opened vertically, and the track opening is located between every two fish discharge openings.

[0016] The above technical solution is adopted: three sections of pipes are combined into one pipe to play multiple roles, which solves the pain point of farmers and breeding enterprises that dead fish cannot be automatically discharged during the breeding process, and also reduces the labor for dead fish salvage and observation and patrol; it solves the pain point that floating objects such as oil film and foam on the water surface in the breeding process, especially after feeding, take a long time to fade away, making water quality treatment more efficient and effective, and visibility is greatly improved.

[0017] Preferably, the track pipe is arranged transversely. The suspension pipe and the chassis insert pipe are provided with several small holes, the diameter of the holes is determined according to the specification of the culture species, and the number of the holes is determined according to the designed flow rate of the circulating water culture system.

[0018] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0019] The three-section automatic sewage pipe for recirculating aquaculture uses three sections of pipes to form one pipe, which can play multiple roles. It solves the pain point of farmers and aquaculture companies that they cannot automatically drain dead fish during the aquaculture process, and also reduces the labor for dead fish salvage and observation patrols.

After moving upward, sick fish or dead fish are discharged to the outside of the breeding pond through the fish discharge port 101 and collected by the drainage pipe, thereby achieving the purpose of discharging sick fish and dead fish without affecting the normal operation of the system.
