Description

Technical Field

[0001] This utility model relates to the field of jellyfish experimental technology, and in particular to an experimental device for repelling jellyfish. Background Technology

[0002] Jellyfish tentacles are covered with nematocysts invisible to the naked eye, which can inject toxins into human skin, causing pain, blisters, and other symptoms. Jellyfish stings are becoming increasingly common, and people working or engaging in activities at sea are encountering these venomous jellyfish more frequently, impacting their health.

[0003] Currently, clinical treatment for jellyfish stings is primarily symptomatic, with long treatment cycles and numerous side effects. Prevention can effectively avoid these potential dangers. Repelling jellyfish can significantly reduce the probability of stings, thereby reducing unnecessary pain and medical costs, and alleviating fear when engaging in water activities. To understand jellyfish repellency, conducting repellency experiments is crucial, but to date, no relevant jellyfish repellency experimental models or devices have been reported. Utility Model Content

[0004] This invention addresses the problems and shortcomings of existing technologies by providing a jellyfish repellency experimental device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a jellyfish repellency experimental device, characterized in that it includes a water tank, and two partitions are vertically slidably connected inside the water tank, the partitions dividing the inner cavity of the water tank into three chambers arranged from left to right;

[0007] The two partitions are raised and lowered in tandem.

[0008] The three chambers are arranged from left to right as follows: the first chamber for placing the test substance, the second chamber for jellyfish activity before the experiment, and the third chamber as a blank control.

[0009] It also includes a camera device, which is installed above or in front of the water tank, with the detection direction of the camera device facing the water tank;

[0010] It also includes a timer, which is mounted on the water tank.

[0011] This invention enables a jellyfish repellency experiment. Before the experiment, jellyfish are placed in the second chamber for movement. After the partition is opened, the first, second, and third chambers are connected, and the distribution and number of jellyfish in the three chambers are recorded by a camera device.

[0012] In a further preferred embodiment, the tops of the two partitions are connected by a crossbar, which serves as a gripping lever.

[0013] By gripping the crossbar, the two partitions can be raised and lowered synchronously.

[0014] More preferably, the water tank is provided with two U-shaped protrusions arranged on the left and right, and the inner side of the U-shaped protrusions is provided with a U-shaped groove for vertically sliding connection of the partition plate;

[0015] The U-shaped slide groove includes a vertical slide groove portion for vertically slidingly connecting the front and rear sides of the partition and a horizontal slide groove portion for vertically inserting into the bottom of the partition. The two ends of the horizontal slide groove portion are connected to the vertical slide groove portion.

[0016] Easy to insert partitions.

[0017] More preferably, a silicone layer is fixed to the outer edge of the partition.

[0018] This facilitates a better seal at the connection between the partition and the water tank.

[0019] More preferably, it also includes a light-emitting base, wherein the light-emitting direction of the light-emitting base is upward, and the light-emitting base is located below the first chamber;

[0020] A reflector is hinged to the top of the first chamber, the reflector rests on the top of the water tank, and the reflector faces downwards.

[0021] This facilitates testing the repellency of light against jellyfish.

[0022] More preferably, a support frame is provided on the side wall of the first chamber, and a vertically arranged pipe is inserted into the support frame. The bottom of the pipe is higher than the bottom of the first chamber, and a seepage hole is provided on the pipe.

[0023] This facilitates the dripping of the test reagent into the tubing, allowing for drug penetration. It also prevents outward splashing caused by the dripping of the drug.

[0024] More preferably, the top of the pipe has a funnel-shaped opening that is wider at the top and narrower at the bottom.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] This invention has a simple structure. By setting up partitions to divide the water tank into three areas, the escape tendency of jellyfish can be clearly shown when the partitions are removed. This effectively demonstrates the repellency effect of the test substance and fills the gap in jellyfish repellency devices under laboratory conditions.

[0028] This invention uses a partition to fix the swimming range of jellyfish before contact with the drug, keeping the jellyfish from contacting the test substance and maintaining their life and vitality in a fixed area; at the same time, video recording can conveniently record the distribution of jellyfish in different areas after contact with the drug, forming a complete experimental record.

[0029] The model animal selected in this invention, the red moon jellyfish, has the ability to swim independently, avoiding the influence of water flow, thus making the experimental jellyfish avoidance device usable for scientific research.

[0030] This invention, by selecting the size of the water tank, is mainly intended to simulate the impact on jellyfish within the range of human activity after the drug diffuses in seawater, thus avoiding large-scale damage to the ocean and achieving an effective repellent effect.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0036] like Figures 1 to 3Specific embodiment 1: A jellyfish repellency experimental device includes a water tank 1. Two vertically slidable partitions 2 are connected inside the water tank 1, dividing the inner cavity of the water tank 1 into three chambers arranged from left to right. The two partitions 2 are linked and raised / lowered. The three chambers are, from left to right, a first chamber 11 for placing the test substance, a second chamber 12 for jellyfish activity before the experiment, and a third chamber 13 as a blank control. The device also includes a camera, with its detection direction facing the water tank 1, and a timer 4, which is hung on the water tank 1. This invention realizes a jellyfish repellency experiment. Before the experiment, jellyfish are uniformly placed in the second chamber 12. When the partitions 2 are opened, the first chamber 11, the second chamber 12, and the third chamber 13 are connected, and the number of jellyfish in each chamber is recorded by the camera.

[0037] The tops of the two partitions 2 are connected by a crossbar 3, which serves as a gripping lever. By gripping the crossbar 3, the two partitions 2 can rise and fall synchronously.

[0038] The water tank 1 is provided with two U-shaped protrusions 14 arranged on the left and right. The inner side of the U-shaped protrusions 14 is provided with a U-shaped groove for vertically slidingly connecting the partition 2. The U-shaped groove includes a vertical groove part for vertically slidingly connecting the front and rear sides of the partition 2 and a horizontal groove part for vertically inserting into the bottom of the partition 2. The two ends of the horizontal groove part are connected to the vertical groove part to facilitate the insertion of the partition 2.

[0039] A silicone layer is fixed to the outer edge of the partition 2. This improves the sealing performance at the connection between the partition 2 and the water tank 1. A U-shaped silicone layer is fixed to the outer edge of the partition 2, covering the front, back, and bottom sides. Alternatively, a U-shaped sealing ring is fixed to the outer edge of the partition 2, covering all four sides of the partition 2. The silicone layer is located at the contact point between the U-shaped groove and the partition 2.

[0040] See Figure 3 A support frame 5 is provided on the side wall of the first chamber 11. A vertically arranged pipe 6 is inserted into the support frame 5. The bottom of the pipe 6 is higher than the bottom of the first chamber 11, and a seepage hole is opened on the pipe 6. This facilitates the dripping of the test substance into the pipe 6 through the test reagent, achieving the permeation of the test substance and avoiding outward splashing caused by direct dripping of the test substance. The top of the pipe 6 is a funnel-shaped opening that is wider at the top and narrower at the bottom. The support frame 5 is provided with hooks for hanging on the side wall of the water tank 1, and a through hole is opened on the support frame 5 for inserting the pipe.

[0041] Water tank 1 is a transparent acrylic water tank with dimensions of 50*10*15cm. Partition 2 is an acrylic partition.

[0042] The method of using this device is as follows:

[0043] Before starting the experiment, pour an appropriate amount of artificial seawater into tank 1, with a salinity of 25%-30%, 1-2 cm from the top of tank 1. By grasping the crossbar 3, insert the partition 2, and place 5 healthy red moon jellyfish of the same size into the second chamber 12, allowing them to swim freely for 5 minutes.

[0044] Using a pipette, add 5 mL of the test substance to the first chamber 11 through tubing 6 and allow it to diffuse for 10 minutes; add 5 mL of seawater to the third chamber 13. After 10 minutes, remove the partition 2 by gripping the crossbar 3, and record the distribution and number of jellyfish in the three chambers using a camera device within a certain time (e.g., 5 minutes).

[0045] Analysis of the distribution and number of jellyfish in the three chambers recorded by the camera device showed that the sparser the jellyfish in the first chamber 11 and the denser the jellyfish in the second chamber 12 and the third chamber 13, the higher the repellency rate, proving that the jellyfish repellency effect of the test substance is better.

[0046] After the experiment, the jellyfish were removed, tank 1 was cleaned, and the water was changed. A new batch of jellyfish that had not been in contact with the sample was then used to conduct a jellyfish repellency experiment targeting the next test substance.

[0047] like Figure 4 In specific embodiment 2, based on specific embodiment 1, a light-emitting base 7 is further included. The light-emitting base 7 faces upward and is located below the first chamber 11. A reflector 8 is hinged above the first chamber 11 and overlaps the top of the water tank 1, with the reflector 8 facing downward. The light emitted by the light-emitting base 7 passes through the first chamber 11 to the reflector 8, forming a light curtain within the first chamber 11, which facilitates the testing of the repellency of light against jellyfish.

[0048] The usage method is as follows:

[0049] Before starting the experiment, pour an appropriate amount of artificial seawater into tank 1, with a salinity of 25%-30%, 1-2 cm from the top of tank 1. By grasping the crossbar 3, insert the partition 2, and place 5 healthy red moon jellyfish of the same size into the second chamber 12, allowing them to swim freely for 5 minutes.

[0050] By grasping the horizontal bar 3, the partition 2 is removed, the light-emitting base 7 is turned on, and light of a certain intensity is emitted. The distribution and number of jellyfish in the three chambers are recorded by the camera device within a certain time (e.g., 5 minutes).

[0051] Analysis of the distribution and number of jellyfish in the three chambers recorded by the camera device showed that the sparser the jellyfish in the first chamber 11 and the denser the jellyfish in the second chamber 12 and the third chamber 13, the higher the repellency rate, proving that light is more effective at repelling jellyfish.

[0052] After the experiment, the jellyfish were removed, tank 1 was cleaned, and the water was changed. A new batch of jellyfish was then introduced to conduct a jellyfish avoidance experiment for the next intensity of light.

[0053] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
