Description

Technical Field

[0001] This utility model belongs to the field of fish fry hatching and breeding technology, and specifically relates to a fish fry hatching pond. Background Technology

[0002] As shown in the patent document with publication number CN105010195B, fish eggs are all semi-buoyant eggs. When hatching in still water, they will pile up together, gradually sink, and accumulate at the bottom, resulting in insufficient dissolved oxygen, slow embryonic development, and even suffocation and death. However, when hatching in flowing water, the fertilized eggs float in the water under the action of the water flow, keeping the fry in a floating state. The flowing water can also provide sufficient dissolved oxygen, allowing the fry to fully hatch.

[0003] After the fish fry hatch, the size of their growth environment greatly influences their development. Once the fry reach a certain length, they are transferred to avoid hindering their growth rate. Workers use nets to catch the fry, but because the fry are fragile, the nets easily damage them during capture. Furthermore, their small size and extremely fast swimming speed result in low harvesting efficiency. Therefore, those skilled in the art have provided a fish fry hatching pond to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a fish fry hatching pond to solve the technical problem in the background art where the stirring of the net during the catching process can easily damage the fish fry.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fish fry hatching pond includes: a hatching pond shell and a base, wherein the bottom of the hatching pond shell extends downward at an angle, and three bases are equidistantly arranged, with the top of the three bases fixedly connected to the hatching pond shell.

[0007] A barrier post is fixedly inserted into the axis of the hatching pool shell. A support assembly and a barrier net are slidably sleeved on the surface of the barrier post. The barrier net is disposed inside the support assembly, and the support assembly is disposed inside the hatching pool shell.

[0008] A water guide box is located below the barrier post. A water outlet pipe is fixedly inserted into one side of the water guide box. A filter bucket is fixedly inserted into one end of the water outlet pipe. A water pump is fixedly connected inside the filter bucket. A water guide pipe is fixedly connected to the output end of the water pump. One end of the water guide pipe extends towards the side close to the outer shell of the hatching pool.

[0009] Furthermore, a filter screen is fixedly connected inside the barrier post, and multiple filter screens are arranged at equal intervals.

[0010] Furthermore, a steering pipe is rotatably inserted into the middle of the water guide pipe, and both ends of the steering pipe are interconnected with the water guide pipe.

[0011] Furthermore: the support assembly includes two fixing rings that slide against the inner wall of the hatching pool shell, and a support column is fixedly inserted between the two fixing rings. Multiple support columns are equidistantly arranged, and the outer wall of the barrier net is fitted against the inner wall of the two support columns.

[0012] Furthermore: a collar is slidably fitted to the outer wall of the barrier post, and multiple connecting rods are fixedly connected at equal intervals around the collar. One end of each of the multiple connecting rods is fixedly connected to the inner wall of the fixed ring, and the upper part of the collar is fixedly connected to the lower part of the barrier net.

[0013] Furthermore: the inner wall of the hatching pool shell extends downward at an angle, the bottom of the inner wall of the hatching pool shell is attached to the bottom of one of the supporting columns, and a gap is left between the bottom of the net and the hatching pool shell.

[0014] Furthermore: the three bases are located around the water guide box, with gaps between them, and the bottom of the water guide box is at the same horizontal level as the three bases.

[0015] Furthermore, a sealing ring is installed at the connection between the lower part of the barrier post and the outer shell of the hatching pool, and the lower part of the outer shell of the hatching pool is fixedly connected to the water guide box.

[0016] In summary, this utility model has the following beneficial effects:

[0017] Workers insert the support components along the inner wall of the hatching tank shell, and fix the net inside the support components. The barrier posts and the net form a breeding environment that can block the fish eggs. Workers inject breeding water into the inside of the hatching tank shell. The water flows through the hollow inside of the barrier posts into the water guide box and the water outlet pipe into the filter tank. Workers start the water pump. The inlet end of the water pump is equipped with a filter box, which can prevent impurities from entering the water guide pipe through the water pump. The water will enter the inside of the hatching tank shell through the water guide pipe, so that the water completes the water circulation, increases the oxygen content in the water and purifies the water quality. When the fish fry grow to a certain length, the workers lift the support components. The support components will drive the net to rise. When the bottom of the net rises to a certain height above the water surface, the net will concentrate the fish fry near the water surface, and the workers will then catch the fish fry, which greatly increases the efficiency of fish fry transfer.

[0018] The outer walls of the two fixing rings slide horizontally against the inner wall of the hatching pool. The two fixing rings are supported by support columns. The barrier net consists of a protective net and a bottom net. The inner walls of the two support columns fix the barrier net, increasing its stability inside the hatching pool. The barrier net can be raised by lifting the fixing rings. The top of the collar supports the bottom net of the barrier net, allowing the inner wall of the bottom net to slide against the outer wall of the barrier column. The collar is supported by a connecting rod between its four sides and a support column. The barrier net is unfolded inside the hatching pool using one collar and two fixing rings, facilitating the hatching of fish fry. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] A fish fry hatching pond includes: a hatching pond shell 1, a base 2, a barrier post 4, and a water guide box 11. The bottom of the hatching pond shell 1 extends downward at an angle. Three bases 2 are equidistantly arranged, and the upper parts of the three bases 2 are fixedly connected to the hatching pond shell 1. The barrier post 4 is fixedly inserted into the axis of the hatching pond shell 1. A support component 5 and a net 7 are slidably fitted on the surface of the barrier post 4. The net 7 is located inside the support component 5, which is located inside the hatching pond shell 1. The water guide box 11 is located below the barrier post 4. A water outlet pipe 12 is fixedly inserted into one side of the water guide box 11. A filter bucket 3 is fixedly inserted into one end of the water outlet pipe 12. A water pump 8 is fixedly connected inside the filter bucket 3. A water guide pipe 9 is fixedly connected to the output end of the water pump 8. One end of the water guide pipe 9 extends towards the side close to the hatching pond shell 1. The barrier post (4) is hollow inside and has through holes on its surface. The interior of the barrier post 4 is connected to the water guide box 11 and the water outlet pipe 12 below.

[0028] In this process, when the fish fry are hatching, the workers will disinfect the inside of the hatching tank shell 1. Then, a barrier post 4 is inserted into the center of the hatching tank shell 1. The inside of the barrier post 4 is connected to the water guide box 11 and the water outlet pipe 12 below. Then, the workers will put the support component 5 along the inner wall of the hatching tank shell 1. The net 7 is fixed inside the support component 5. The barrier post 4 and the net 7 form a breeding environment that can block the fish eggs.

[0029] Workers inject aquaculture water into the interior of the hatching tank shell 1. The water flows through the hollow interior of the barrier post 4 into the water guide box 11 and the outlet pipe 12, entering the interior of the filter bucket 3. Workers start the water pump 8, which has a filter box installed at the inlet end to prevent impurities from entering the interior of the water guide pipe 9. The water then flows through the water guide pipe 9 into the interior of the hatching tank shell 1, completing the water circulation, increasing the oxygen content in the water and purifying the water quality. When the fry grow to a certain length, workers lift the support component 5, which in turn raises the barrier net 7. When the bottom of the barrier net 7 rises to a certain height above the water surface, the barrier net 7 concentrates the fry near the water surface, allowing workers to catch them, greatly increasing the efficiency of fry transfer.

[0030] The barrier post 4 has a filter screen 6 fixedly connected inside. Multiple filter screens 6 are evenly spaced. The center of the barrier post 4 has a hollow structure to facilitate water flow. During the water flow, it will pass through multiple water outlets inside the barrier post 4. Multiple filter screens 6 are fixed inside the multiple water outlets of the barrier post 4. The filter screens 6 can block the fish fry and prevent them from escaping as much as possible.

[0031] Preferably, a swivel tube 91 is rotatably inserted into the middle of the water guide pipe 9. The two ends of the swivel tube 91 are interconnected with the water guide pipe 9. The outer diameter of the swivel tube 91 is the same as the outer diameter of the water guide pipe 9. The diameters of the two ends of the swivel tube 91 are smaller than the inner diameter of the water guide pipe 9. The two ends of the swivel tube 91 extend into the interior of the water guide pipe 9. The water guide pipe 9 and the swivel tube 91 guide the water output by the water pump 8 to the hatching tank shell 1. When the worker lifts the support assembly 5, the worker guides the orientation of the water guide pipe 9 to avoid collision between the water guide pipe 9 and the support assembly 5.

[0032] Specifically, the support component 5 includes a fixing ring 51 that slides and fits against the inner wall of the hatching pool shell 1. There are two fixing rings 51, and a support column 52 is fixedly inserted between the two fixing rings 51. Multiple support columns 52 are equidistantly arranged. The outer wall of the barrier net 7 fits against the inner wall of the two support columns 52.

[0033] The outer walls of the two fixing rings 51 slide horizontally against the inner wall of the hatching pool shell 1. The two fixing rings 51 are supported by the support column 52. The net 7 is divided into a protective net and a bottom net. The inner walls of the two support columns 52 fix the net 7, increasing the stability of the net 7 inside the hatching pool shell 1. The net 7 can be raised by lifting the fixing rings 51.

[0034] More specifically, a collar 54 is slidably fitted to the outer wall of the barrier post 4. Multiple connecting rods 53 are fixedly connected at equal intervals around the collar 54. One end of each connecting rod 53 is fixedly connected to the inner wall of a fixing ring 51. The upper part of the collar 54 is fixedly connected to the lower part of the barrier net 7. The upper part of the collar 54 supports the bottom net of the barrier net 7, so that the inner wall of the bottom net of the barrier net 7 slides against the outer wall of the barrier post 4. The collar 54 is supported by connecting rods 53 between its four sides and a support post 52. The barrier net 7 is unfolded inside the outer shell 1 of the hatching pond by a collar 54 and two fixing rings 51, which facilitates the hatching of fish fry.

[0035] Furthermore, during implementation, the inner wall of the hatching pool shell 1 extends downward at an angle, and the bottom of the inner wall of the hatching pool shell 1 is attached to the bottom of one of the support columns 52. A gap is left between the bottom of the net 7 and the hatching pool shell 1. The support column 52 supports the bottom of the net 7 through the connecting rod 53. The gap between the downward extension of the hatching pool shell 1 and the net 7 prevents the fish eggs from contacting the bottom of the hatching pool shell 1, so that the fish eggs are suspended inside the hatching pool shell 1, increasing the contact between oxygen and fish fry and improving hatching efficiency.

[0036] Brief description of usage:

[0037] When in use, during the hatching process of fish fry, workers will disinfect the inside of the hatching pool shell 1, and then insert the barrier post 4 into the center of the hatching pool shell 1. The inside of the barrier post 4 is connected to the water guide box 11 and the water outlet pipe 12 below. Then, the workers will put the support component 5 along the inner wall of the hatching pool shell 1, and the net 7 will be fixed inside the support component 5. The barrier post 4 and the net 7 together form a breeding environment that can block the fish eggs.

[0038] Workers inject aquaculture water into the interior of the hatching tank shell 1. The water flows through the hollow interior of the barrier post 4 into the water guide box 11 and the outlet pipe 12, entering the interior of the filter bucket 3. Workers start the water pump 8, which has a filter box installed at the inlet end to prevent impurities from entering the interior of the water guide pipe 9. The water then flows through the water guide pipe 9 into the interior of the hatching tank shell 1, completing the water circulation, increasing the oxygen content in the water and purifying the water quality. When the fry grow to a certain length, workers lift the support component 5, which in turn raises the barrier net 7. When the bottom of the barrier net 7 rises to a certain height above the water surface, the barrier net 7 concentrates the fry near the water surface, allowing workers to catch them, greatly increasing the efficiency of fry transfer.
