Description

Technical Field

[0001] This utility model relates to the field of freshwater fish farming technology, and in particular to a small-body independent experimental fish farming device. Background Technology

[0002] In fish farming experiments, such as those on fish physiology, pathology, toxicology, and breeding, multiple experimental farming devices are often required. Small numbers of fish are raised individually in each small water body. Currently, these small water body farming devices mainly consist of tanks and additional separate water and oxygen supply structures, without effectively integrating the tank structure. As a result, when conducting multiple experimental farming experiments, the operation is not only complicated, but the water in the tanks cannot accurately simulate the natural water flow conditions. Therefore, the fish growth can be negatively impacted during the experimental farming process, thus affecting the experimental results. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a small-body independent experimental aquaculture device for fish.

[0004] The first aspect of this application provides a small-body independent experimental aquaculture device for fish, comprising:

[0005] Base;

[0006] A breeding tank is disposed on the top surface of the base, and an installation structure is provided on the inner side wall of the breeding tank cavity;

[0007] Water and oxygen supply structure, the water and oxygen supply structure comprising:

[0008] A water-oxygen supply body is disposed on the surface of the mounting structure, and the water-oxygen supply body has a first cavity and a second cavity spaced apart.

[0009] A short inlet pipe is disposed on the surface of the water-oxygen supply body and communicates with the first cavity.

[0010] The oxygen supply pipe is connected to the second cavity;

[0011] A ramp structure is provided on the opposite surface where the mounting structure and the water-oxygen supply structure are connected.

[0012] In some possible embodiments, a top cover is also included, which can be selectively fastened to the top surface of the aquaculture tank.

[0013] In some possible embodiments, the ramp structure and the mounting structure are arranged along the height direction of the aquaculture tank.

[0014] In some possible embodiments, the ramp structure includes a ramp body, the front end of which is provided with an arc-shaped surface.

[0015] In some possible embodiments, a pin is provided on the side end face of the ramp body, and a limiting through hole is provided on the surface of the mounting structure, with the pin inserted into the limiting through hole.

[0016] In some possible embodiments, the inner sidewall of the aquaculture tank cavity is provided with two installation structures at intervals, and the water and oxygen supply structure and the slope structure are respectively provided on the opposite surface of each installation structure.

[0017] In some possible embodiments, the water outlet directions of the two water-oxygen supply structure surfaces provided with inlet short pipes are along the same circumferential direction.

[0018] In some possible embodiments, the surface of the aquaculture tank is provided with a plurality of overflow outlets communicating with the cavity.

[0019] In some possible embodiments, multiple overflow outlets are staggered along the vertical direction on the surface of the aquaculture tank.

[0020] In some possible embodiments, the bottom surface of the aquaculture tank is provided with a drain outlet that communicates with the cavity.

[0021] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects:

[0022] 1) By setting up a sloping structure and an installation structure inside the breeding tank, the sloping structure is set with a smooth curved surface from low to high along the circumference of the breeding tank. A water-oxygen supply structure is installed on the surface of the installation structure on the highest side of the sloping structure. The surface of the water-oxygen supply structure is equipped with a short water inlet pipe and an oxygen supply pipe. One end of the water-oxygen supply structure is connected to an external water and air source through a pipeline. During the independent experimental breeding in a small water body, by controlling the amount and flow rate of water entering the water-oxygen supply structure, a turbulent flow is generated at the short water inlet pipe, so that the water in the breeding tank can circulate. At the same time, oxygen can be supplied, which better simulates the water flow of the natural environment and facilitates the independent experimental breeding of fish in a small water body.

[0023] 2) By setting an overflow outlet on the side wall of the culture tank, water can be discharged from the overflow outlet as the volume increases. The drain outlet at the bottom of the culture tank facilitates the drainage and cleaning operations of the culture personnel. The water and oxygen supply structure is integrated into the inner side wall of the culture tank, making the entire culture device occupy less space, which is convenient for transportation and deployment of multiple culture devices for independent small-scale fish experiments. At the same time, setting overflow outlets at different heights allows for water level control according to the experimental requirements of different fish species, improving the applicability of the culture device.

It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0042] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of multiple aquaculture devices 100 and overflow pipeline system 200 shown in the embodiments of this application. Multiple aquaculture devices 100 are set up independently, and each small fish independent experimental aquaculture device 100 can conduct experiments under different conditions, such as experiments on fish physiology, pathology, toxicology, and breeding. The overflow pipeline system 200 is connected to the overflow drain of each aquaculture device 100, so that the overflow water of each aquaculture device 100 can be collected during the aquaculture process. During the experiment, each aquaculture device 100 needs to be connected to an external water pump and air pump to supply water and oxygen to the aquaculture device 100. The external water pump and air pump (not shown in the figure) can be obtained from the market and can be selected according to actual needs. The specific structure of the aquaculture device 100 will be described below through multiple embodiments.

[0045] Please see Figures 2 to 5The aquaculture device 100 includes a base 110, an aquaculture tank 120, a water and oxygen supply structure 130, and a top cover 150. The base 110 is used in conjunction with the aquaculture tank 120. The base 110 is mainly used to support the aquaculture tank 120 so that the drain outlet at the lowest end of the aquaculture tank 120 is a certain distance from the ground, so as to facilitate the connection of the pipes from the drain outlet. The base 110 and the aquaculture tank 120 can be connected by snap-fit ​​or other means. The specific shape of the base 110 is not limited here. The top cover 150 can be selectively fastened to the top surface of the aquaculture tank 120. The specific shape of the top cover 150 is not limited here. For example, a mesh window can be set to facilitate the observation of the fish farming situation in the tank and prevent the fish from escaping.

[0046] In some embodiments, the breeding tank 120 includes a tank body 121 with a conical bottom. The tank body 121 is disposed on the top surface of the base 110. An installation structure 122 is provided on the inner side wall of the cavity of the tank body 121. The installation structure 122 is disposed along the height of the breeding tank 120. It should be noted that the installation structure 122 has two intersecting side surfaces. Of course, the side surfaces can also be disposed opposite to each other.

[0047] It should be noted that the shape of the mounting structure 122 can be a triangular structure with a flat surface, which can achieve the installation and fixation of the water and oxygen supply structure 130. The specific shape of the mounting structure 122 is not limited. The connection between the water and oxygen supply structure 130 and the mounting structure 122 can be achieved by a pin or a snap-fit ​​connection. For example, limit holes 1221 are provided on both sides of the mounting structure 122, and pins are provided on the corresponding surfaces of the water and oxygen supply structure 130 and the ramp structure 140 to achieve a detachable connection. The specific connection process will not be described in detail here.

[0048] In some embodiments, the ramp structure 140 has a smooth surface arranged from low to high along the circumferential direction of the breeding tank 120, and one side of the smooth surface extends to the mounting structure 122. The water and oxygen supply structure 130 is disposed on the surface of the mounting structure 122. The shape of the breeding tank 120 can be a cylindrical upper part and a conical bottom with a certain slope. The ramp structure 140 and the mounting structure 122 are arranged along the height direction of the breeding tank 120.

[0049] Optionally, two ramp structures 140 are spaced apart on the inner side wall of the cavity of the breeding tank 120. The two ramp structures 140 are preferably distributed on both sides of the diameter passing through the central axis of the breeding tank 120. The ramp distribution direction of the two ramp structures 140 is the same, that is, simultaneously along clockwise or counterclockwise. When there are two ramp structures 140, the installation structure 122 and the water and oxygen supply structure 130 can also be set to two.

[0050] It should be noted that, with the ramp structure 140, when the water and oxygen supply structure 130 introduces water into the tank, the water circulation at the inlet generates a turbulent flow, increasing the water's fluidity and causing the breeding tank 120 to rotate clockwise or counterclockwise. The ramp structure 140 reduces the resistance to the water flow within the tank. At the same time, the water volume and flow rate entering the breeding tank 120 can be adjusted via the water valve.

[0051] Optionally, the surface of the breeding tank 120 is provided with several overflow ports 123 that communicate with the cavity. The multiple overflow ports 123 are staggered along the vertical direction on the surface of the breeding tank 120. The overflow ports 123 are mainly used to automatically overflow when the water and oxygen supply structure 130 continuously adds water to the breeding tank 120, so as to maintain the water level in the breeding tank 120. At the same time, they also remove pollutants from the water source in the breeding tank 120.

[0052] Optionally, a drain outlet 124 is provided at the bottom of the breeding tank 120. The drain outlet 124 can be set coaxially with the breeding tank 120. At the same time, the drain outlet 124 can also remove sediment from the water source inside the breeding tank 120.

[0053] Optionally, a filter structure can be installed at the overflow outlet 123 and the drain outlet 124 to filter the discharged water, and at the same time, it can also be used as an incubation facility for the breeding tank 120.

[0054] Please see Figure 6 and Figure 7 The water-oxygen supply structure 130 includes a water-oxygen supply body 131, a connecting pipe 132, a water inlet short pipe 133, and an oxygen supply pipe 134. The water-oxygen supply body 131 has a first cavity 1311 and a second cavity 1312 spaced apart. The first cavity 1311 and the second cavity 1312 are completely isolated. The connecting pipe 132 is provided on the top of the water-oxygen supply body 131. The connecting pipe 132 includes a water connecting pipe 1321 and an air connecting pipe 1322. The water connecting pipe 1321 and the air connecting pipe 1322 are connected to an external water pump and an air pump to provide water and air sources. The water inlet short pipe 133 is provided on the surface of the water-oxygen supply body 131 and is connected to the first cavity 1311. The oxygen supply pipe 134 is connected to the second cavity 1312.

[0055] Optionally, a short water inlet pipe 133 and an oxygen supply pipe 134 can be installed on the bottom side end face of the water and oxygen supply body 131 to achieve sufficient oxygen supply to the breeding tank 120. The oxygen supply pipe 134 can be obtained from the market, and the specific one can be selected according to actual needs.

[0056] In some embodiments, such as Figure 8As shown, the ramp structure 140 may include a ramp body 141. One side of the ramp body 141 has an arc surface that fits against the inner wall of the bucket, and the opposite side also has an arc surface. The arc surface away from the bucket wall extends from one end to the end surface 142 of the ramp structure 140. The end surface 142 can fit against the side surface of the mounting structure 122. Two pins 143 are provided on the end surface 142. It should be noted that a rubber block is provided at the front end of the pin 143. The outer contour of the rubber block is slightly larger than the diameter of the limiting through hole 1221. In this way, when the pin is inserted into the limiting through hole 1221, the ramp structure 140 is fixed, and it is also easy to disassemble.

[0057] The aquaculture device 100 in the above embodiment includes a ramp structure 140 and an installation structure 122 within the aquaculture tank 120. The ramp structure 140 has a smooth curved surface that rises from low to high along the circumference of the aquaculture tank 120. A water-oxygen supply structure 130 is installed on the surface of the installation structure 122 at the highest side of the ramp structure 140. The water-oxygen supply structure 130 has a water inlet pipe and an oxygen supply pipe 134. One end of the water-oxygen supply structure 130 is connected to an external water and air source through a pipeline. During small-scale independent aquaculture experiments, the amount and flow rate of water entering the water-oxygen supply structure 130 are controlled to generate a turbulent flow at the water inlet pipe, causing the water in the aquaculture tank 120 to circulate. At the same time, oxygen can be supplied, better simulating the natural water flow conditions, which is conducive to small-scale independent aquaculture experiments for fish.

[0058] Furthermore, by setting an overflow outlet 123 on the side wall of the breeding tank 120, water can be discharged from the overflow outlet 123 as the water volume increases. The drain outlet set at the bottom of the breeding tank 120 facilitates the drainage and cleaning operations of the breeding personnel. In addition, a water and oxygen supply structure 130 is integrated into the inner side wall of the breeding tank 120, making the entire breeding device occupy less space, which is convenient for transportation and arrangement. Multiple breeding devices can be arranged to conduct independent experiments in small water bodies for fish. The space occupied is small, and multiple sets of experimental devices can be placed. Each set can be used for different experimental treatments and parallel experiments can be carried out.
