Description

Technical Field

[0001] The utility model relates to the technical field of mixed culture in breeding ponds, and in particular to a bullfrog breeding device and a mixed culture system. Background Art

[0002] Aquaculture ponds are artificial bodies of water used specifically for the cultivation of aquatic plants and animals. They are usually used to cultivate aquatic organisms such as fish, shrimp, and shellfish. In aquaculture ponds, environmental factors such as water quality, temperature, and light can be controlled to promote the growth and reproduction of aquatic organisms. The design and management of aquaculture ponds are crucial to the success of the aquaculture industry.

[0003] Mixed culture of fish and shrimp in aquaculture ponds is a common aquaculture method that can effectively utilize space and resources and improve aquaculture efficiency. In aquaculture ponds where fish and shrimp are mixed, some fish and shrimp that are coordinated with each other are usually selected for mixed culture to achieve resource complementarity and ecological balance. In aquaculture ponds where fish and shrimp are mixed, bullfrogs are usually cultured in cages in the aquaculture ponds. Mixed culture of fish, shrimp and bullfrogs can not only improve aquaculture efficiency, but also promote each other in mixed culture to form an ecological balance, while avoiding adverse interactions with fish and shrimp.

[0004] CN203968974U discloses a cage device for raising bullfrogs in a fish pond, comprising a cage which is square and is supported by wooden piles on all sides and is set up in the fish pond. The cage is immersed in water and 2-6 foam floats floating on the water surface are arranged in the cage.

[0005] The above technical solution can effectively improve the utilization rate of the upper water and space of the fish pond, save arable land, increase the unit water output of the fish pond, save fish feed input, and increase the breeding income. However, due to the complex underwater environment of the breeding pond, the wooden stakes cannot be inserted to the same depth, resulting in the cages being in a high and low state, and the bullfrogs in the low places are easy to run out, and the top is uneven, which has certain limitations when harvesting bullfrogs; for the bottom of the cage, during the breeding process, the bottom mud formed by excrement, food residues, etc. will accumulate at the bottom of the cage, resulting in an unstable cage, and the above technical solution uses multiple foam floats, which will float when affected by wind and waves, and will scare the bullfrogs.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] refer to Figures 1 to 8 A bullfrog breeding device includes a frame 21, a plurality of support columns 22, a cage assembly 23, a connector 24, and a float assembly 25. The plurality of support columns 22 are detachably connected to the edges of the frame 21 and are used to horizontally fix the frame 21 in an external pond. The cage assembly 23 is hung in the frame 21 and forms a breeding area with an open upper surface in the frame 21. The float assembly 25 is movably connected to the plurality of support columns 22 through a plurality of connectors 24. The float assembly 25 is located in the breeding area and forms a shallow water area with the water surface of the pond. A deep water area is provided between the edge of the float assembly 25 and the cage assembly 23.

[0024] Under this design, it is best for two operators to complete the installation operation. One operator first stabilizes the position of the frame 21, and the other operator fixes multiple support columns 22 in the preset positions of the fish and shrimp mixed breeding pond in turn. Since the structural conditions at the bottom of the breeding pond cannot be determined, when fixing the support columns 22, it cannot be guaranteed that the support columns 22 can be fixed at the same depth, but each support column 22 needs to ensure its stability. Then the operator fixes the frame 21 on the support columns 22 and ensures that the frame 21 is in a horizontal state. After the frame 21 is fixed, the net cage assembly 23 is first hung in the frame 21, and then the float assembly 25 is movably connected to the multiple support columns 22 through multiple connecting parts 24, so that the float assembly 25 can establish shallow water areas and deep water areas in the breeding area, and finally the bullfrog is placed in the formed breeding area.

[0025] In this way, it is ensured that the frame 21 can be horizontally fixed in the external pond, and the cage assembly 23 can be horizontally hung in the frame 21, ensuring the stability of the frame 21 and the cage assembly 23, and the float assembly 25 is movably connected to the multiple support columns 22 through multiple connectors 24, which is convenient for replacing the float assembly 25. The shallow water area formed by the float assembly 25 and the water surface of the pond can better meet the living environment of the bullfrog, so that the bullfrog can live on the float assembly 25, and the bullfrog will not interfere with the fish and shrimp in the cage assembly 23, thereby realizing the mixed breeding of fish, shrimp and bullfrog.

[0026] In this embodiment, the frame 21 includes an upper frame 211 and a lower frame 212 which are arranged correspondingly in the upper and lower parts, and a plurality of connecting tubes 213 for connecting the upper frame 211 and the lower frame 212. The sides of the plurality of connecting tubes 213 are simultaneously connected to the sides of the upper frame 211 and the lower frame 212. The upper frame 211 and the lower frame 212 are respectively detachably connected to a plurality of support columns 22 through the plurality of connecting tubes 213. The bottom of the connecting piece 24 is in contact with the top of the upper frame 211, and the floating plate assembly 25 is hung on the upper frame 211 or the lower frame 212.

[0027] Furthermore, a connecting hole 2131 is provided on the side of the connecting pipe 213 , and the connecting hole 2131 is located between the upper frame 211 and the lower frame 212 . The connecting pipe 213 passes through the connecting hole 2131 by bolts to detachably connect the upper frame 211 and the lower frame 212 to the support column 22 .

[0028] Therefore, the purpose of the frame 21 being composed of an upper frame body 211 and a lower frame body 212 is to be able to set the connecting hole 2131 on the connecting pipe 213 between the upper frame body 211 and the lower frame body 212. This can not only prevent waves from directly washing the connecting hole 2131 and the bolts to a certain extent, but also prevent the excrement of some birds from sticking to the connecting hole 2131 and the bolts.

[0029] In actual use, after the multiple support columns 22 are fixed, the upper frame 211 and the lower frame 212 can slide along the length direction of the support column 22 through the connecting tube 213 to adjust the upper frame 211 and the lower frame 212 to a suitable height, and then the upper frame 211 and the lower frame 212 are fixed to the support column 22 by bolts passing through the connecting holes 2131, thereby completing the fixing of the upper frame 211 and the lower frame 212. In addition, the upper frame 211 and the lower frame 212 can be connected by the connecting tube 213, and they can be welded when in use.

[0030] Preferably, the upper frame 211 and the lower frame 212 are both square structures, the number of the connecting tubes 213 is at least four, the number of the supporting columns 22 matches the number of the connecting tubes 213, and the supporting columns 22 are retractable structures.

[0031] It should be noted that the upper frame 211 and the lower frame 212 are not limited to a square structure, but can also be a circular, polygonal or other structure. The square structure design can more effectively utilize space, reduce space waste, and is suitable for various occasions and needs. In addition, because the square structure has four corners, there are at least four connecting pipes 213, so as to ensure the stability of the connection between the upper frame 21 and the lower frame 21.

[0032] The telescopic structure adopted by the support column 22 can adopt the mode of an outer tube 221 and an inner tube 222, that is, the outer tube 221 is sleeved on the inner tube 222, and then the outer tube 221 and the connecting tube 213 are detachably connected, two holes 2211 arranged up and down are arranged on the side of the outer tube 221, a button 2221 is arranged on the inner tube 222, and the button 2221 is connected to the inner tube 222 through a spring (not shown in the figure), when in use, the button 2221 can be stuck in the hole 2211 located above the outer tube 221, when it is necessary to extend, press the button 2221 and push the outer tube 221 upward, so that the button 2221 is stuck in the hole 2211 located below the outer tube 221, so as to achieve length adjustment. Of course, other methods can also be adopted, and this method is only preferred.

[0033] Preferably, there are four connecting pipes 213, and they are respectively located at the four corners of the upper frame 211 and the lower frame 212. The four connecting pipes 213 are located at the four corners of the upper frame 211 and the lower frame 212, so that the four corners of the square structure have connection points, ensuring the stability of the connection between the upper frame 211 and the lower frame 212.

[0034] In this embodiment, a reinforcing rod 214 is provided on both the upper frame 211 and the lower frame 212, one side of the reinforcing rod 214 is connected to the side of the connecting tube 213, and the other side of the reinforcing rod 214 is provided with a first hook 2141. The cage assembly 23 is hung on the reinforcing rod 214 of the upper frame 211 or the reinforcing rod 214 of the lower frame 212.

[0035] Specifically, the purpose of the reinforcing rod 214 is to strengthen the connection stability between the upper frame 211 and the connecting pipe 213, and the lower frame 212 and the connecting pipe 213, and by providing a first hook 2141 on the other side of the reinforcing rod 214, the cage assembly 23 can be selectively hung on the reinforcing rod 214 of the upper frame 211 or on the reinforcing rod 214 of the lower frame 212. Because there are four connecting pipes 213, there are also four reinforcing rods 214, which are respectively located at the four corners. The cage assembly 23 needs to be hung at the four corners at the same time to ensure the stability of the cage assembly 23.

[0036] As a further optimization of this embodiment, the connecting member 24 includes a connecting ring 241 and a connecting rope 242. The connecting ring 241 is movably connected to the support column 22. A second hook 2411 is provided on the connecting ring 241. The floating plate assembly 25 is connected to the second hook 2411 through the connecting rope 242.

[0037] In actual application, the connecting ring 241 is movably mounted on the support column 22, that is, the connecting ring 241 can contact the top of the upper frame 211 under the action of gravity, and the floating plate assembly 25 is hung on the second hook 2411 through the connecting rope 242 to position the floating plate assembly 25 in the net cage assembly 23. When replacing, it is only necessary to take out the connecting ring 241 upward in the length direction of the support column 22. By setting the connecting ring 241 and the connecting rope 242, it can be ensured that the floating plate assembly 25 is always located at a designated position in the net cage assembly 23, and the floating plate assembly 25 is prevented from moving due to waves. In addition, the operator should use a connecting rope 242 of appropriate length.

[0038] Furthermore, the floating plate assembly 25 includes a connecting frame 251 and an elastic soft plate 252 connected to the connecting frame 251. The connecting frame 251 is connected to the second hook 2411 through a connecting rope 242. The connecting frame 251 is used to position the elastic soft plate 252 under the water surface.

[0039] Specifically, the function of the connecting frame 251 is to make the elastic soft board 252 located under the water surface to form a shallow water area with the water surface. In addition, the purpose of using the elastic soft board 252 is that when it is necessary to take the bullfrog, the contact between the scoop net and the elastic soft board 252 can deform the elastic soft board 252 to a certain extent, making it easier to take the bullfrog out.

[0040] More preferably, the elastic soft plate 252 is provided with a plurality of through slots 2521. The purpose of providing the through slots 2521 is, firstly, to facilitate the excrement of the bullfrog to fall from the through slots 2521 to the bottom of the net cage assembly 23; secondly, when the scoop net contacts the elastic soft plate 252, the elastic soft plate 252 can be further deformed, making it easier to scoop out the bullfrog; thirdly, to facilitate the bullfrog to enter the deep water area from the shallow water area.

[0041] As for the replacement of the floating plate assembly 25, when there is too much moss on the elastic soft plate 252, resulting in excessive physical residues and excrement accumulation on it, it is only necessary to release the connection relationship between the connecting ring 241 and the elastic soft plate 252, remove it, and then replace it with a new elastic soft plate 252. By providing a plurality of through grooves 2521 in the elastic soft plate 252, it can be directly inserted when replacing, and the bullfrog pressed by the elastic soft plate 252 will crawl out from the through grooves 2521. In addition, the elastic soft plate 252 can be made of materials such as rubber or PVC.

[0042] In this embodiment, a sunshade cloth (not shown in the figure) is also included, and the sunshade cloth is hung on the top of the plurality of support columns 22. The sunshade cloth can provide a sunshade environment and can also prevent birds from entering the breeding area.

[0043] refer to Figure 7 In this embodiment, there is also a polyculture system, including a fish and shrimp polyculture pond 1, in which the above-mentioned breeding device 2 is provided, and the area of ​​the breeding device 2 is 8 to 10% of the area of ​​the fish and shrimp polyculture pond 1.

[0044] Under this design, multiple breeding devices 2 can be set up in the fish and shrimp mixed culture pond 1 at the same time, but the premise of setting up multiple devices is that it does not affect the feeding of fish and shrimp, and it is necessary to ensure that the breeding devices 2 and the fish and shrimp mixed culture pond 1 do not interfere with each other. As for the supply of oxygen, because bullfrogs are added to the fish and shrimp mixed culture pond 1, the required oxygen will increase, but the bullfrogs in the breeding device 2 can share a set of oxygenation system with the fish and shrimp in the fish and shrimp mixed culture pond 1.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
