Description
Technical Field
The utility model relates to a fish culture technical field, concretely relates to silvery pomfret circular breed pond drainage instrument.
Background
Silvery pomfret is one of the main marine economic fishes in China, has delicious meat quality and higher nutritional value and market demand, but in recent years, due to over-fishing and environmental deterioration, the germplasm resources of wild silvery pomfret in China have obvious signs of decline, so that domestic researchers begin to develop the artificial breeding work of silvery pomfret successively. In the indoor artificial breeding process, the pomfret likes the cluster to swim around, so that the pomfret is artificially cultured in the circular culture pond. The round culture pond adopts a central drainage mode, a water outlet is easy to generate strong vortex, and young pomfret individuals have poor small mobility and easily move along with water, and are easily sucked to the position of the water outlet with more rapid water flow during drainage, so that scales fall off or are scratched. Meanwhile, the draining method is easy to cause frightened collision of the pomfret parr, so that fish body damage is caused, and finally, a great amount of death of the pomfret parr is caused. In addition, part of the juvenile fish can be sucked on the drain hole of the drain pipe, so that the drain pipe is blocked, and drainage is affected. Through reading the literature and the actual farm survey, no efficient and safe drainage tool for the round pomfret culture pond is found at present.
Disclosure of Invention

In order to solve the technical problem, the utility model relates to a round pond drainage instrument of breeding of silvery pomfret, include: the pomfret cultivating device comprises a steel frame, a fixing device and a fixing device, wherein the steel frame is made of stainless steel, the upper part and the lower part of the steel frame are respectively provided with a circular steel ring with the same size, the middle part of the steel frame is provided with four supporting steel bars with the same length to form a cylindrical structure, four connecting steel bars extend out of the joint of the circular steel rings and the supporting steel bars and are gathered on an iron ring in the middle of the steel frame for fixing a plastic pipe, the supporting steel bars are slightly inclined downwards to enable the steel frame to be more attached to the bottom of a pomfret circular cultivating pool, the plastic pipe is a white PVC pipe, and the pipe wall of the plastic pipe is provided with holes for draining water; the screen is sewn into a cylinder shape, and the size of the screen is the same as that of the steel frame, so that the screen can be tightly sleeved on the periphery of the steel frame and cannot fall off; the cloth has been sewed up with the steelframe tie point department respectively to the cloth, and respectively there are eight from top to bottom, can be with the billet junction of gauze system on the steelframe, avoid the gauze to drop and rock when the drainage, gauze both ends opening, and the size of mesh can be adjusted according to the size of breeding fish.
Preferably, the diameter of the circular steel ring is 80cm, the length of the supporting steel bar is 120cm, and the diameter of the central iron ring of the steel frame is 30 cm.
Preferably, the plastic tube is 130cm in diameter and 30cm in diameter.
Preferably, the mesh of the gauze has a pore diameter of 0.2cm and a mesh size of 10 to 20 meshes.
Preferably, the length of the cloth strip is 15 cm.
The utility model discloses the advantage:
1. vortex can not be generated at the water outlet, water drainage is gentle, scales can be prevented from falling off or being scratched due to frightening of the pomfret, and the death rate of the pomfret in the breeding process is greatly reduced.
2. The problem that the water drainage pipe is blocked and the water drainage is influenced because the juvenile fish can be sucked on the water drainage hole of the water drainage pipe can be avoided.

As shown in the figure: 1-steel frame, 1.1-steel ring, 1.2-supporting steel bar, 1.3-iron ring, 1.4-connecting steel bar; 2-plastic tube, 3-gauze and 4-cloth strip.
Detailed Description
The water draining tool for round pomfret cultivating pond of the present invention is further described in detail with reference to the following examples.
As shown in figure 1, the utility model relates to a drainage tool for a round pomfret culture pond, which comprises a steel frame 1, a plastic pipe 2, a gauze 3 and a cloth strip 4. Firstly, a plastic pipe 2 with the length of 130cm and the diameter of 30cm is fixed on an iron ring in a steel frame 1, the height of the plastic pipe is adjusted up and down to enable the upper part of the plastic pipe to be exposed out of the water surface, the lower part of the plastic pipe is tightly attached to the bottom of a pool, then a gauze 3 is sleeved on the steel frame 1, a cloth strip 4 is tied to enable the gauze to be tightly fixed on the steel frame, and the position of the cloth strip is preferably used for preventing the gauze from shaking back and forth at the joint of the steel frame during drainage. And finally, directly sleeving the assembled drainage device on a central drainage pipe of the round pomfret culture pond for use.
As shown in fig. 2, the upper and lower parts of the steel frame 1 are respectively provided with a circular steel ring 1.1 with the same size, the middle part of the steel frame is provided with four supporting steel bars 1.2 with the same length to jointly form a cylindrical structure, the four supporting steel bars 1.2 are extended out of the joint of the circular steel ring 1.1 and the supporting steel bars 1.2 and are gathered on an iron ring 1.3 in the middle of the steel frame to be used for fixing a plastic pipe 2, and the supporting steel bars 1.2 are slightly inclined downwards to enable the steel frame 1 to be more attached to the bottom of the round pomfret culture pond.
The device is used in the process of water change in pomfret cultivation, and the specific operation method comprises the following steps:
the plastic pipe 2 is firstly fixed in an iron ring 1.3 in the steel frame 1, so that the upper end of the plastic pipe 2 can be above the water surface during drainage, and the lower end of the plastic pipe can be tightly attached to the bottom of the pool, thereby not only ensuring the drainage speed, but also preventing young pomfret from being sucked away. Then, the gauze 3 is sleeved on the periphery of the steel frame 1, the mesh size of the gauze 3 can be adjusted according to the size of cultured fishes, the principle is that the dirt in the pool such as residual bait, excrement and the like passes through the gauze, the cultured silvery pomfret in the pool does not pass through the gauze, the gauze 3 is tightly fixed on the steel frame 1 by tying the cloth strips, and the position of the cloth strips 4 is preferably used for preventing the gauze 3 from shaking back and forth at the joint of the steel frame 1 during drainage. When the device is used, the assembled device is sleeved on a drain pipe of a round silvery pomfret culture pond from top to bottom, after drainage is completed, a drain valve is closed, then the device is lifted out of the culture pond, and the gauze 3 needs to be cleaned regularly during use, so that mesh blockage is avoided. The device is convenient to assemble and simple to operate, sewage can be normally discharged during drainage, the suction force of vortex to the pomfret parr in the culture pond can be effectively reduced, meanwhile, the steel frame and the gauze can also protect fish schools from being far away from the water outlet, so that the safety of the cultured pomfret is guaranteed to the maximum extent, and the death rate of the pomfret in the culture process is greatly reduced.
The above examples are merely illustrative of the technical concept and technical features of the present invention, and thus the scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the essence of the present invention should be covered within the protection scope of the present invention.
