Description

Technical Field

[0001] This utility model relates to the field of shrimp farming experimental technology, and in particular to a shrimp farming experimental device. Background Technology

[0002] Stocking density refers to the number of cultured organisms per unit area or volume. The stocking density of shrimp has a significant impact on their growth performance, disease resistance, and overall farming efficiency. Furthermore, the required stocking density varies depending on the species, stage, and size of the shrimp. Therefore, experimental exploration and research on controlling stocking density in shrimp farming are crucial. Although there are numerous existing experimental devices for shrimp farming, such as the utility model patent CN 216853466U "A Biological Experimental Device for Redclaw Crayfish" and CN216314879 U "A Sealed Water Tank for Shrimp Larvae Experiments," no experimental devices specifically addressing shrimp stocking density have been found. In shrimp farming, adjusting shrimp stocking density typically involves controlling the shrimp population or transferring them to different sized tanks or ponds. Controlling the population, such as reducing stocking density, requires removing shrimp, which can potentially cause mechanical injury or stress to other shrimp. Transferring shrimp requires multiple tanks or ponds of varying sizes, increasing costs. Therefore, it is necessary to improve existing technologies and provide experimental shrimp farming devices that take stocking density into account. Utility Model Content

[0003] Therefore, based on the above background, this utility model provides a shrimp farming experimental device. This utility model takes into account the impact of stocking density on shrimp farming, and adjusts the compartments within the stocking box by means of an adjustment component, so as to control the stocking density and better conduct experiments on the impact of stocking density on shrimp.

[0004] The technical solution provided by this utility model is as follows: An experimental apparatus for shrimp farming includes a square culture box having a cavity; An adjustment component is mounted on the breeding box, and the adjustment component can adjust the division of the box cavity by moving along the length of the breeding box; A limiting component, comprising a silicone suction cup, is used to restrict the movement of the adjusting component by adhering to the wall of the breeding box via the silicone suction cup.

[0005] Furthermore, the adjustment component includes a partition, the upper part of which is provided with a 7-shaped support plate; the support plate is provided with a limiting component.

[0006] Furthermore, the support plate includes a horizontal plate and a vertical plate; The limiting assembly also includes a control plate and a control rod. The upper part of the control plate is rotatably mounted on the lower part of the vertical plate, and one end of the control rod is rotatably mounted on the lower part of the control plate. The end of the control rod away from the control plate is connected to a silicone suction cup.

[0007] Furthermore, an inclined plate is provided below the partition, and the inclined plate is provided with toothed plates.

[0008] Furthermore, the partition plate has water passage holes.

[0009] Furthermore, the breeding box is also equipped with an aeration component.

[0010] Furthermore, the bottom plate of the breeding box has a hollow cavity; The aeration assembly includes a main pipe, on which branch pipes extending along the width of the breeding box are provided, and on which vertical vent pipes are provided, the vent pipes communicating with the box cavity.

[0011] Furthermore, the top of the breeding box is provided with a mounting plate, and the horizontal plate has mounting holes that cooperate with the mounting plate.

[0012] Furthermore, the breeding box is made of transparent material.

[0013] The beneficial effects of adopting the above technical solution are as follows: This invention uses an adjustment component to divide and adjust the chambers inside the breeding box. By adjusting the volume of the divided chambers, the breeding density of shrimp can be controlled, and the effect of breeding density on shrimp can be experimentally explored. This invention eliminates the need to prepare multiple breeding boxes of different sizes, thus saving experimental costs. Compared to controlling the stocking density by reducing the number of shrimp, this invention controls the stocking density of shrimp by moving the adjusting component left and right, which can reduce or avoid mechanical damage or stress to the shrimp during the process of catching them.

[0014] This invention regulates shrimp stocking density by adjusting the left and right movement of the regulating component, enabling various experiments on the effects of regulating stocking density. For example, this invention can also regulate the stocking density by adjusting the size of the shrimp living chamber, i.e., regulating the stocking density, to conduct experiments on the effects of regulating the stocking density of the same batch of shrimp at different stages; or it can conduct experiments on the effects of different stocking densities on the same batch of shrimp, with the same number of shrimp located in separate chambers of different volumes.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0027] In the description of this utility model, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the indicated features.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1: According to Figures 1 to 5 , Figures 8 to 9 The shrimp farming experimental device shown includes a square farming box 1, which has a cavity. An adjustment component 2 is mounted on the breeding box 1. The adjustment component 2 can adjust the box cavity by moving along the length of the breeding box 1. A limiting component, comprising a silicone suction cup 27, wherein the limiting component is attached to the wall of the breeding box 1 by the silicone suction cup 27 to restrict the movement of the adjusting component.

[0030] The adjustment component 2 includes a partition 21, and a 7-shaped support plate 24 is provided on the upper part of the partition 2; a limiting component is provided on the support plate 24.

[0031] The mounting plate 24 includes a horizontal plate and a vertical plate 241; the limiting assembly further includes a control plate 25 and a control rod 26. The upper part of the control plate 25 is rotatably mounted on the lower part of the vertical plate 241, and one end of the control rod 26 is rotatably mounted on the lower part of the control plate 25. The end of the control rod away from the control plate 25 is connected to a silicone suction cup 27. The limiting assembly prevents non-human-caused movement of the partition, thus avoiding interference with the control of the chamber's partitioning.

[0032] Specifically, such as Figure 2 and Figure 3As shown, the control board is rotatably mounted on a vertical plate via a first rotating shaft. The control board is provided with a first mounting block, and the lower part of the vertical plate is provided with a first groove. The first mounting block is mounted in the first groove via the first rotating shaft, and the first mounting block passes through the first rotating shaft. Both ends of the first rotating shaft are fixed to the sidewalls of the first groove.

[0033] The lower part of the control panel is provided with a second groove, and the upper part of the control rod is installed in the second groove through a second rotating shaft, with the control rod passing through the second rotating shaft. The two ends of the second rotating shaft are fixed to the sidewall of the second groove.

[0034] In specific applications, the limiting component, such as Figure 7 or Figure 8 As shown, the control lever is rotated 90° toward the breeding box, and then moved toward the box wall to squeeze the silicone suction cup, causing the air inside the silicone suction cup to be expelled and adsorbed onto the outer wall of the breeding box under negative pressure. During this process, the control plate rotates to accommodate the movement of the control lever toward the box wall.

[0035] Preferably, the control lever or control panel is made of plastic and is hollow to reduce its weight and minimize its impact on the suction cup's adsorption. Furthermore, the partition and inclined plate can be made of plastic, more specifically, transparent plastic such as polycarbonate or polystyrene, but the material is not limited.

[0036] Below the partition 21, there is an inclined plate 22, and the inclined plate 22 is provided with toothed plates 221. Specifically, as shown below... Figure 4 As shown, the gap formed between the toothed plates 221 of the inclined plate 22 needs to correspond to the volume of the shrimp in the breeding box, that is, it needs to be controlled to prevent the shrimp from passing through. Specifically, the tilt angle of the inclined plate 22 can be controlled between 15-60°, preferably less than 30°. The inclined plate with a tilt angle can be moved more easily, and combined with the toothed plates, especially when adjusting the volume of the partitioned box where the shrimp are located by moving, it can push or pull the shrimp and the items in the box. Another example is that the toothed plates can be covered with a silicone layer, which, combined with the slow movement of the partition, can better reduce mechanical damage to the shrimp. In specific applications, one embodiment is as follows: Figures 1 to 4 As shown in Figure 5, the number of inclined plates is one. Preferably, as shown in Figure 5, the number of inclined plates is two, symmetrically arranged below the partition, so that when the partition is moved to adjust the separation chamber by moving the partition to the left or right, both sides can be moved by pushing the shrimp and the items in the chamber.

[0037] The partition 21 has water passage holes 211. In a specific application, the water passage holes 211 can be vertical strip holes, the width of which corresponds to the volume of the shrimp in the breeding tank, that is, it is necessary to control and prevent the shrimp from passing through.

[0038] This invention, through a partition with water passage holes and an inclined plate with toothed plates, can reduce the influence of the water environment (e.g., temperature) in different compartment chambers during certain experiments, such as the control experiments listed below.

[0039] In practical applications, multiple adjustment components with different water passage holes can be installed in the same rearing tank to adapt to shrimp of different sizes. For example, in an experiment on the stocking density of the same batch of shrimp at different growth stages, if an adjustment component adapted to the juvenile shrimp to be placed in one of the compartments is installed in the rearing tank at the beginning of the experiment, the gaps between the toothed plates and the water passage holes of this adjustment component will not allow the juvenile shrimp to pass through.

[0040] In practical applications, the side of the partition or inclined plate can be attached to the side wall of the breeding box or have a certain gap, which must prevent juvenile shrimp from passing through. Alternatively, the bottom wall of the inclined plate can be attached to the bottom wall of the breeding box or have a certain gap, preferably having a certain gap, and similarly, this gap must prevent juvenile shrimp from passing through.

[0041] The top of the breeding box 1 is provided with a mounting plate 11, and the horizontal plate has mounting holes 23 that cooperate with the mounting plate 11.

[0042] The breeding box is made of transparent material to facilitate observation inside the breeding box.

[0043] The breeding box is made of transparent glass or transparent plastic, and the plastic material can be polycarbonate or polystyrene, and the material is not limited.

[0044] Furthermore, the outer wall of the breeding box can be smoothed, for example, polished, to facilitate the adsorption and fixation of the silicone suction cup.

[0045] In practical applications, the breeding box is equipped with one or more adjustment components with the same water passage holes. The chamber of the breeding box can be divided according to the needs of the adjustment components. For example, when conducting a control experiment on different breeding densities for shrimp, one adjustment component can be used to divide the chamber, or two adjustment components can be used to divide the chamber according to the needs. After the chamber is divided to a suitable volume by moving the partition, juvenile shrimp are introduced.

[0046] In practical applications, such as in an experiment to investigate the impact of changes in stocking density on the farming results of shrimp from the same batch at different growth stages, this embodiment can be conducted as follows: Determine the juvenile shrimp to be tested, and select an adjustment component with appropriate water passage holes based on the size of the juvenile shrimp. Place the partition as follows: Figure 1 As shown, the device is set up inside the breeding box and moved along the length of the box to a suitable position to divide the box cavity. The silicone suction cup is then attached to the box wall using the limiting component. Water and other materials (such as algae or small stones) are added to the breeding box according to experience. Then, an equal or unequal number of juvenile shrimp are placed into one or two of the divided cavities. Depending on the time or the different stages of the juvenile shrimp's growth, the partition is moved left and right after the silicone suction cup detaches from the box wall to adjust the volume of the divided cavities. If juvenile shrimp are placed in both divided cavities, a direct comparison can be made.

[0047] Alternatively, in experiments exploring the impact of the same stocking density on shrimp farming, the procedure can be as follows: Determine the juvenile shrimp to be tested, and select one or more adjustment components with appropriate water passage holes according to the size of the juvenile shrimp. Place the partition as follows: Figure 1 As shown, the device is set up inside the breeding box and moved along the length of the box to a suitable position to divide the box cavity. The silicone suction cup is then attached to the box wall using the limiting component. Water and other materials (such as algae or small stones) are added to the breeding box according to experience. Then, an equal or unequal number of juvenile shrimp are placed into one or more of the divided cavities. The partition is moved left and right to adjust the volume of the divided cavities. If juvenile shrimp are placed in multiple divided cavities, a direct comparison can be made.

[0048] This invention is applicable to experiments on juvenile or adult shrimp. During the experiment, if egg-bearing female shrimp are found, they need to be specially observed or removed before spawning, and the results should be recorded to avoid the impact of egg hatching on the experiment. The egg-bearing rate of the female shrimp is also one of the factors in evaluating the influence of stocking density. Of course, the above is merely a demonstration of an experiment using this invention. For other experiments, this invention can be adapted to specific needs. The design of the experiment and its use do not affect the structure and function of this invention.

[0049] Example 2: According to Figures 1 to 9 The shrimp farming experimental device shown in this embodiment, compared with embodiment 1, is further provided with an aeration component 3 in the farming box, through which oxygen is supplemented to the farming box.

[0050] The bottom plate of the breeding box 1 has a hollow cavity 12; the aeration assembly 3 includes a main pipe 31, and the main pipe 31 is provided with a branch pipe 32 extending along the width direction of the breeding box 1. The branch pipe 32 is provided with a vertical air pipe 33, and the air pipe 33 is connected to the box cavity.

[0051] In practical applications, one implementation is that the vent pipe 33 passes through the bottom wall of the box, and its end face can be flush with the bottom plate of the box or lower than the bottom wall of the inclined plate, so as to facilitate the left and right movement of the adjustment component.

[0052] Alternatively, the vent pipe 33 may protrude from the bottom wall of the box, and the bottom of the inclined plate may have a through hole (not shown) that cooperates with the vent pipe 33 and allows it to pass through.

[0053] The main improvement of this utility model involves adjusting the shrimp farming density. Other farming conditions, such as light control and temperature control, are not within the scope of this utility model's improvement. For example, for light control, adjustable lights can be installed on the farming tank, or light-blocking plates can be used appropriately during the experiment. These are all specific applications of this utility model and are conventional operations in the field, so they will not be described in detail. Temperature control is the same as light control.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
