Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding barrels, and more specifically, to a fish breeding barrel which is convenient for adjusting water levels and cleaning residues. Background Art

[0002] Fish breeding barrels are commonly used for fish fry cultivation and adult fish farming of snakehead fish, sea bass, loach, tilapia, yellow croaker, grass carp and crucian carp.

[0003] Existing fish tanks on the market are typically simple, large, tendon barrels or basins. These are incapable of handling residual water and are inconvenient to change. This leads to the accumulation of feces and fish food debris when using these tanks, which in turn increases ammonia and nitrite levels in the water, polluting the water quality and impacting fish growth. Maintaining healthy water quality requires frequent daily water changes and the removal of settled debris, which consumes considerable time and effort. Furthermore, manual water changes make it difficult to accurately control the water level. Overdraining the tank can lead to insufficient water, making the fish uncomfortable, while overfilling can cause overflow. Utility Model Content

[0004] In order to overcome the defects of the existing technology, the utility model proposes a fish breeding barrel that is convenient for adjusting the water level and cleaning the residue. When changing the water, the water level in the breeding barrel can be simply and accurately controlled. At the same time, through the aquatic plant planting plate, not only can the fish be separated from the residue, but the aquatic plants can also absorb and degrade the fecal residue, realize waste utilization, and provide shelter and partial oxygen for the fish in the barrel, which is beneficial to the survival of the fish.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a fish breeding barrel which is convenient for adjusting the water level and cleaning the residue, comprising a breeding barrel body, an aquatic plant planting plate, a first valve and a drain pipe, wherein the aquatic plant planting plate is arranged in the breeding barrel body, a water inlet is arranged at the top of one side of the breeding barrel body, the first valve is arranged at the bottom of the breeding barrel body, and the drain pipe comprises a first main pipe, a branch pipe, a second valve and a second main pipe, the first main pipe and the second main pipe are arranged horizontally and coaxially, more than two branch pipes arranged in sequence from top to bottom are connected in parallel between the first main pipe and the second main pipe, and the branch pipe located at the bottom is arranged coaxially with the first main pipe, the second valve is arranged on the branch pipe, and the free end of the first main pipe is connected to the first valve.

[0007] In a preferred technical solution of the present invention, the free end of the second main pipe is connected to an arc-shaped pipe via a connector, and a third valve is provided on the arc-shaped pipe.

[0008] In a preferred technical solution of the present invention, the first main pipe is further connected to an air pipe, and a fourth valve is provided on the air pipe.

[0010] In a preferred technical solution of the present invention, the breeding barrel and the second valve located at the bottom are both provided with support feet.

[0011] The beneficial effects of the utility model are:

[0012] The present invention proposes a fish farming barrel that facilitates water level adjustment and debris cleaning. By installing aquatic plant planting panels and a drain pipe, the water in the barrel is separated from debris, providing an extremely convenient way to change the water. Water level control is simple and precise, and bottom debris cleaning is simple and efficient, saving considerable time and effort during farming. The drain pipe also utilizes a multi-valve design. By controlling the sequence of valve opening and closing, water can be stored within the pipe and a negative pressure is generated within the pipe, enhancing suction on the bottom of the barrel during the next drain, improving cleaning efficiency. The planted aquatic plants absorb and degrade fecal debris, achieving waste recycling. They also provide shelter and some oxygen for the fish within the barrel, benefiting their survival. The support legs facilitate the transport of the barrel during daily farming and isolate the bottom of the barrel from the ground, reducing the adverse effects of rapidly fluctuating ground temperatures on the water temperature within the barrel.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1-2As shown, an embodiment provides a fish breeding barrel that is convenient for adjusting the water level and cleaning residues, including a breeding barrel body 1, an aquatic plant planting plate 2, a first valve 3 and a drain pipe 4. The aquatic plant planting plate 2 is provided in the breeding barrel body 1, a water inlet 11 is provided at the top of one side of the breeding barrel body 1, and a first valve 3 is provided at the bottom of the breeding barrel body 1. The drain pipe 4 includes a first main pipe 41, a branch pipe 42, a second valve 43 and a second main pipe 44. The first main pipe 41 and the second main pipe 44 are arranged horizontally and coaxially. More than two branch pipes 42 arranged from top to bottom are connected in parallel between the first main pipe 41 and the second main pipe 44, and the branch pipe 42 at the bottom is coaxially arranged with the first main pipe 41. The second valve 43 is provided on the branch pipe 42, and the free end of the first main pipe 41 is connected to the first valve 3. In this embodiment, the aquaculture barrel 1 is made of a high-quality tendon barrel. An aquatic plant planting plate 2 is horizontally arranged within the aquaculture barrel 1, dividing the interior of the aquaculture barrel 1 into upper and lower layers, wherein the upper layer is a breeding layer and the lower layer is a residue layer. Aquatic plants that absorb and degrade aquatic waste, such as water hyacinth and snapdragon, are also planted on the aquatic plant planting plate 2. These plants can absorb residue and nitrates in the water, maintaining clean and safe water quality and sufficient oxygen content, while also providing shelter for fish. Both the first valve 3 and the second valve 43 are manual valves that can be manually opened and closed by staff. The drainage pipe 4 is used to discharge waste from the residue layer in the breeding barrel 1 to ensure good water quality. Among them, the first main pipe 41 and the second main pipe 44 are both located below the breeding barrel 1 to ensure that the water in the breeding barrel 1 can be completely drained; the branch pipe 42 is arranged horizontally, and by opening and closing the second valve 43 at different heights, it is convenient to control the water level inside the breeding barrel 1, and the operation is convenient; in addition, by controlling the opening and closing sequence of the valves, water can be stored in the pipeline between the first valve 3 and the second valve 43, so that a siphon effect can be formed when the water is released next time, thereby producing a filtering effect on the bottom of the breeding barrel 1.

[0019] Specifically, the free end of the second manifold 44 is connected to an arc-shaped tube 46 via a connector 45. A third valve 47 is provided on the arc-shaped tube 46. In this embodiment, the arc-shaped tube 46 is arc-shaped and faces downward, making it less susceptible to clogging. The third valve 47 is used to control the opening and closing of the arc-shaped tube 46.

[0020] Specifically, the first main pipe 41 is further connected to an air pipe 48, which is provided with a fourth valve 49. In this embodiment, the fourth valve 49 is used to control the opening and closing of the air pipe 48. When the air pipe 48 is opened, it can balance the air pressure inside and outside the first main pipe 41, thereby completely draining any remaining water from the first main pipe 41.

[0021] Specifically, at least two through holes 21 are evenly distributed on the aquatic plant planting plate 2. In this embodiment, the size of the through holes 21 should be determined according to the size of the fish being cultured, ensuring that debris and plant roots can reach the bottom of the aquatic plant planting plate 2 while preventing fish from passing through, thereby creating an environment in which the culture layer is separated from the debris layer.

[0022] Specifically, support legs 5 are provided on both the aquaculture barrel 1 and the second valve 43 at the bottom. In this embodiment, the support legs 5 are equipped with steerable rollers. When the device needs to be moved, the support legs 5 can be used to push the aquaculture barrel 1 to its destination, reducing the manual handling required and facilitating the transport of the entire aquaculture barrel for use in aquaculture. Furthermore, the support legs 5 insulate the bottom of the aquaculture barrel 1 from the ground, reducing the adverse effects of rapidly fluctuating ground temperatures on the water temperature within the barrel.

[0023] Working principle: When in use, first open the first valve 3, and according to the water level requirement of the breeding barrel body 1, open the second valve 43 of the corresponding height, and then add water to the breeding barrel body 1 through the water inlet 11. When the water level in the breeding barrel body 1 is higher than the height of the opened second valve 43, the excess water will be discharged from the drain pipe 4 to achieve simple and precise control of the water level. When adding water, the water level of the breeding barrel body 1 should exceed the aquatic plant planting plate 2. The upper part of the aquatic plant planting plate 2 is the fish breeding layer, and the lower part is the residue layer. Fish excrement and food residues can fall into the residue layer below through the through hole 21 on the aquatic plant planting plate 2, while the fish are blocked in the clean breeding layer above. After the water is added, close the first valve 3 and the second valve 43 so that water is stored in the first main pipe 41, and then open the second valve 43 at the bottom. At this time, due to the effect of the external atmospheric pressure, the residual water in the pipe cannot be completely discharged, but due to the gravity of the water, the residual water in the pipe will continue to overcome the air pressure and be discharged partially. At this time, close all the valves again to form a certain negative pressure in the pipe, so that a suction filtration effect can be generated during the next drainage, and the bottom of the barrel can be cleaned more thoroughly.

[0024] When drainage is required, the first valve 3, the second valve 43 at the bottom, and the third valve 47 are opened. Water then flows down the curved pipe 46 and simultaneously draws out impurities from the bottom of the aquaculture tank 1, achieving a filtration effect. When drainage is complete, the first and second valves 3 and 43 are closed in sequence, and the water is stored again in the first main pipe 41 for future use. If this filtration function is not required and the water in the pipe is to be completely drained, the fourth valve 49 can be opened after closing the first valve 3 to equalize the atmospheric pressure inside and outside the first main pipe 41 and drain the remaining water.

[0025] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
