Description

An underwater animal experimental system Technical Field

[0001] This invention belongs to the field of underwater animal experiments in diving medicine, and in particular relates to an underwater animal experiment system. Background Technology

[0002] Diving medicine, also known as underwater medicine, is a discipline that studies and addresses various medical issues arising during diving operations. This includes research on the physiological responses and pathological changes of organisms working in underwater and high-pressure environments, the prevention and treatment of diving-related diseases, and the hygienic requirements and medical support measures for diving operations. Research in diving medicine typically begins with animal experiments before progressing to human trials.

[0003] When conducting underwater animal experiments, factors such as the relative position of the experimental animals on the restraint cage and the size of the experimental animals can cause the underwater animal experimental system to tilt to the heavier side when it is placed underwater. This results in different parts of the animal's body being at different water depths, making it impossible to accurately obtain experimental data on the animal at a specific water depth.

[0004] Traditionally, underwater animal testing systems are hoisted and leveled with counterweights before being submerged. However, this method is problematic because the different displacement volumes of the animals on the system cause it to tilt towards the side with the smaller displacement volume upon deployment, making it difficult to accurately obtain experimental data at the corresponding depths. Therefore, before deployment, researchers attach ropes to both ends of the platform and maintain balance by pulling on these ropes after deployment. Once balanced, the other ends of the ropes are secured to a ground-based anchor. This method undoubtedly increases the workload for researchers and reduces efficiency. Summary of the Invention

[0029] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0030] Please refer to Figures 1-3. This invention provides an underwater animal experiment system, including: a restraint cage 1, a carrying platform 2, an animal experiment support 3, and two underwater automatic balancers 4; the carrying platform 2 is used to fix the restraint cage 1, the top of the carrying platform 2 is connected to the animal experiment support 3, and the bottom of the carrying platform 2 is connected to the two underwater automatic balancers 4; the animal experiment support 3 is provided with a load-bearing lifting ring 329 for hoisting at one end away from the carrying platform 2; one of the two underwater automatic balancers 4 is used to balance the weight at the front and rear ends of the carrying platform 2, and the other is used to balance the weight at the left and right ends of the carrying platform 2; the underwater automatic balancer 4 includes a first support member 41, a counterweight assembly 42, a drive assembly 43, a power supply assembly 44, and a power distribution box; the drive assembly 43, the counterweight assembly 42, and the power supply assembly 44 are disposed on the first support member 41; the counterweight assembly 42 and the drive assembly 43 are respectively There are two components: a counterweight assembly 42 is provided at each end of the first support member 41, and a drive assembly 43 is provided in a one-to-one correspondence with the counterweight assembly 42; the drive assembly 43 is used to drive the counterweight assembly 42 to move along the first support member 41; the energizing assembly 44 is provided between the two counterweight assemblies 42; the energizing assembly 44 includes a first receiving cavity 441, a conductive element 442 and four electrodes 443; the first receiving cavity 441 is provided on the first support member 41; two electrodes are provided at each end of the first receiving cavity 441, one of the two electrodes provided at one end of the first receiving cavity 441 is connected to the distribution box, and the other electrode is connected to the drive assembly 43; the conductive element 442 is movably provided in the first receiving cavity 441, and when the conductive element 442 moves to one end of the first receiving cavity 441, it is used to conduct the two electrodes 443 provided in the first receiving cavity 441. Specifically, the first receiving cavity 441 can be disposed within the first support member 41. Specifically, the first support member 41 has a groove for accommodating the electrode 443 and the conductive element 442. After the electrode and conductive element 442 are placed in the groove, a cover plate is placed over the opening of the groove to achieve a seal, preventing water from entering the groove and affecting the electrical connection between the conductive element 442 and the electrode. It can be understood that the conductive element 442 has a clearance fit with the groove, allowing the conductive element 442 to slide within the groove. Furthermore, the groove can be positioned centrally on the first support member 41, allowing the weight of the two counterweight components 42 to be the same, meaning the counterweight components 42 can be produced in the same batch, reducing production costs. The four electrodes 443 are divided into two groups, symmetrically arranged on the sides of the groove. One electrode in each group is connected to the distribution box, and the other is connected to the drive component 43.When the first support member 41 is tilted, the conductive member 442 slides towards the lower end of the first support member 41 under gravity, thereby connecting to the two electrodes at the lower end. This allows the power from the distribution box to be transmitted to the drive assembly 43 via the electrodes. After the drive assembly 43 is energized, it drives the counterweight assembly 42 at the lower end to move towards the middle of the first support member 41, that is, towards the conductive member 442, so that the first support member 41 gradually becomes flush with the horizontal plane. When the first support member 41 is flush with the horizontal plane, the conductive member 442 is in the middle position of the first receiving cavity 441. At this time, the conductive member 442 is not in contact with either set of electrodes, neither drive assembly 43 is energized, and the relative position of the counterweight assembly 42 and the first support member 41 does not change. The distribution box can be set on the carrying platform 2 of the underwater animal experimental device, or it can be set on the first support member 41, located between the two counterweight assemblies 42. This embodiment does not impose any restrictions on this. It is understood that the distribution box and electrode 443, electrode 443 and drive assembly 43 can be electrically connected via cables.

[0031] The conductive element 442 can be made of a conductive material, or its outer surface can be covered with a coating made of a conductive material; this embodiment does not limit this. In this embodiment, the conductive element 442 has a spherical structure to reduce the friction between the conductive element 442 and the sidewall of the first receiving cavity 441, thereby improving the sensitivity of the energizing component 44. Furthermore, since the conductive element will experience some wear on the sidewall of the first receiving cavity and the conductive element when it moves within the first receiving cavity, a spherical structure can utilize its rolling characteristics to prevent the wear from concentrating on one side, thus avoiding the conductive element failing to contact the electrode and increasing the service life of the underwater automatic balancer. More specifically, in this embodiment, the conductive element 442 is a metal sphere. Of course, in other embodiments, the conductive element 442 can also have other shapes; this embodiment does not limit this, as long as it enables each group of electrodes to conduct electricity.

[0032] One of the two underwater automatic balancers 4 is connected to the bottom of the platform 2, and the other underwater automatic balancer 4 is mounted on top of the one connected to the bottom of the platform 2. The center of the connection between the two underwater automatic balancers 4 is located on the line connecting their centers of gravity. Specifically, the underwater automatic balancers 4 that adjust the weight at the left and right ends of the platform 2 are connected to the platform 2, and the underwater automatic balancers 4 that adjust the weight at the front and rear ends are mounted on the other underwater automatic balancer 4. The center of the connection between the two is located on the line connecting their centers of gravity, which helps the two underwater automatic balancers 4 maintain the balance of the underwater animal experiment system.

[0033] Referring to Figure 3, the underwater automatic balancer 4 also includes a water-sensitive switch 45. The water-sensitive switch 45 is mounted on the first support member 41. One end of the water-sensitive switch 45 is connected to the distribution box, and the other end is connected to an electrode connected to the distribution box; alternatively, one end of the water-sensitive switch 45 is connected to the drive assembly 43, and the other end is connected to an electrode connected to the drive assembly 43. The water-sensitive switch 45 is a switching device capable of detecting changes in water flow and water level. Its main function is to convert the detected water flow signal into an electrical signal, thereby triggering or shutting down the operation of the circuit controller, achieving precise positioning and control of changes in water flow or water level. Specifically, two water-sensitive switches are configured, with one water-sensitive switch 45 corresponding to one drive assembly 43. By configuring the water-sensitive switch 45, when the underwater automatic balancer 4 is in the air, the water-sensitive switch 45 automatically disconnects the electrical connection between the distribution box and the electrode or between the electrode and the drive assembly 43, preventing the conductive element 442 from driving the drive assembly 43 and subsequently the counterweight assembly 42 during transport or installation of the underwater automatic balancer 4. When the underwater automatic balancer 4 is underwater, the water-sensitive switch 45 automatically restores the electrical connection between the distribution box and the electrodes or the electrodes and the drive assembly 43. At this time, the connection between the conductive element 442 and each group of electrodes keeps the balancer parallel to the horizontal plane. In addition, due to the setting of the water-sensitive switch 45, the underwater automatic balancer 4 automatically cuts off power when it is in the air. Therefore, in use, after fixing the restraint cage 1 with the animal to the carrying platform 2 and completing the corresponding preparations, such as putting a breathing mask on the experimental animal and setting up the monitor, the underwater animal experimental system is suspended in the air by using hoisting equipment and connecting the load-bearing ring 329. At this time, the position of the counterweight assembly 42 of the underwater automatic balancer 4 can be manually adjusted to keep the underwater animal experimental system balanced in the air, reducing the adjustment time of the underwater automatic balancer 4 underwater and facilitating the experiment. Then, after entering the water, the water-sensitive switch is automatically powered on, causing the underwater automatic balancer 4 to automatically adjust the position of the counterweight component 42, thereby achieving automatic balance underwater.

[0034] Please refer to Figure 3. The drive assembly 43 includes a drive member 431, a belt 432, a first pulley 433, and a second pulley 434. A second receiving cavity 411 is provided on the first support member 41, and the belt 432, the first pulley 433, and the second pulley 434 are disposed within the second receiving cavity 411. The first pulley 433 is disposed at one end of the second receiving cavity 411, and the second pulley 434 is disposed at the end of the second receiving cavity 411 away from the first pulley 433. The belt 432 is sleeved on the first pulley 433 and the second pulley 434. The first pulley 433 is connected to the drive member 431. The counterweight assembly 42 is connected to the suspended section of the belt 432. The first support member 41 may be provided with a second receiving cavity 411, and the belt 432, the first pulley 433, and the second pulley 434 are disposed within the second receiving cavity 411. Specifically, the second receiving cavity 411 can be a groove provided on the first support member 41, or it can be other structures; this embodiment does not limit this. The drive shaft of the drive component 431 can extend into the second receiving cavity 411 and connect to the first pulley 433. The connection structure between the counterweight assembly 42 and the belt 432 is set on the suspended section of the belt 432. The drive component 431 is connected to the first pulley 433 and is used to drive the first pulley 433 to rotate, thereby driving the counterweight 421 to move. The drive component 431 can be a power output component such as a motor or cylinder. In this embodiment, the drive component 431 is a motor.

[0035] The driving elements 431 of the two driving components 43 are respectively disposed on opposite sides of the first support member 41. Specifically, as shown in Figure 2, one driving element 431 is disposed on the front side of the first support member 41, and the other driving element 431 is disposed on the rear side of the first support member 41. It is understood that since the driving elements 431 have a certain weight, if both driving elements 431 are disposed on the front side or the rear side at the same time, the balancer will tilt towards the side where the two driving elements 431 are disposed due to the influence of the gravity of the driving elements 431. In addition, in other embodiments, the driving elements 431 can be disposed on the upper side or the lower side of the first support member 41 at the same time, or one driving element 431 can be disposed on the upper side and the other on the lower side; since the driving elements 431 are disposed on the upper side or the lower side at the same time, or one driving element 431 can be disposed on the upper side and the other on the lower side, the weight of the front and rear sides of the first support member 41 can be kept consistent, so the underwater automatic balancer 4 will not tilt towards the front or rear side.

[0036] The counterweight assembly 42 includes a counterweight 421 and a connector 422. The connector 422 is sleeved on the first support member 41 and is slidably connected to the first support member 41. The counterweight 421 is connected to the belt 432 through the connector 422. Specifically, the connector 422 may have a through hole that matches the shape of the first support member 41. The connector 422 is sleeved on the first support member 41 through this through hole, and a slidable connection can be achieved through the surface contact between the through hole and the first support member 41. The counterweight 421 can be cylindrical or square. The connector 422 is located at the center of gravity of the counterweight 421 to ensure that the underwater automatic balancer 4 does not tilt due to the uneven weight distribution of the counterweight 421 on the front and rear sides of the first support member 41.

[0037] A second receiving cavity 411 may be provided on the first support member 41, and the belt 432, the first pulley 433, and the second pulley 434 may be disposed within the second receiving cavity 411. Specifically, the second receiving cavity 411 may be a groove provided on the first support member 41, or it may be other structures, which are not limited in this embodiment. The drive shaft of the drive member 431 may extend into the second receiving cavity 411 and connect with the first pulley 433. The connection structure between the connector 422 and the belt 432 may also extend into the receiving cavity and connect with the drive member. The second receiving cavity 411 serves as a receiving structure for the belt 432, the first pulley 433, and the second pulley 434, avoiding interference between the belt 432, the first pulley 433, the second pulley 434 and the connector 422.

[0038] The first support member 41 is also provided with a limiting member for limiting the movement distance of the counterweight assembly 42. Specifically, the limiting member can be a limiting block provided on the first support member 41, and the number can be one, respectively corresponding to the first pulley 433 and the second pulley 434, that is, as a mechanical limiter, limiting the movement distance of the connecting member 422 on the first support member 41.

[0039] Please refer to 1 and 4. The restraining cage 1 includes a restraining cage body 11 and a limiting component 12. The limiting component 12 is disposed on the outer side of the restraining cage body 11. The limiting component 12 includes a first limiting member 121 and a second limiting member 122. The first limiting member 121 is provided with a first sliding groove 1211 extending along its length direction, and the first sliding groove 1211 penetrates the entire length of the first limiting member 121. One end of the second limiting member 122 is connected to the first limiting member 121 to close the first sliding groove 1211. The end of the second limiting member 122 away from the first limiting member 121 is connected to the restraining cage body 1. The outer side of the cage body 11 is flush; a third limiting member 21 is provided on the carrying platform 2, the third limiting member 21 is used to connect with the first sliding groove 1211 of the first limiting member 121, and the second limiting member 122 is used to abut against the end of the third limiting member 21; the underwater animal experiment system also includes a rotating plate 5 and a fixing component 6; the rotating plate 5 is rotatably connected to the bottom of the carrying platform 2, and one side of the rotating plate 5 is used to abut against the outer side of the restraint cage 1; one end of the fixing component 6 is connected to the rotating plate 5, and the other end is connected to the carrying platform 2, for fixing the rotating plate 5 on the carrying platform 2.

[0040] Specifically, the first limiting member 121 can be an elongated structure, which is disposed on the restraint cage body 11. The first groove 1211 is a groove disposed on the side of the first limiting member 121, one end of which is connected to the second limiting member 122, and the other end can be provided with a guide portion. The second limiting member 122 can be a limiting plate disposed on the first limiting member 121, which is used to close one end of the first groove 1211. The guide portion can be an inclined surface cut into the side of the first groove 1211, so as to guide the first groove 1211 when the underwater animal restraint cage 1 is installed on the carrying platform 2, ensuring that the first groove 1211 can be connected with the limiting structure disposed on the carrying platform 2. In one embodiment, there are two first limiting members 121 and second limiting members 122, with the two first limiting members 121 disposed at intervals on the top of the restraint cage body 11, and the first limiting members 121 and second limiting members 122 are disposed in a one-to-one correspondence. The third limiting member 21 can be a long strip structure, and a second sliding groove extending along its length is provided on the third limiting member 21, the second sliding groove penetrating the entire length of the third limiting member 21; the first sliding groove 1211 of the first limiting member 121 is slidably connected to the second sliding groove; the second sliding groove is a groove provided on the strip structure. By providing the second sliding groove, during installation, the first sliding groove 1211 and the second sliding groove are connected. Through the connection of the two sliding grooves, the restraint cage 1 is limited in the vertical and horizontal directions, and the installation of the assembled underwater animal restraint cage 1 is also facilitated.

[0041] The restraining cage body 11 is a cage-like structure formed by multiple perforated plates, with an opening on one side. The length of the top perforated plate of the restraining cage body 11 is shorter than the length of the bottom perforated plate. Specifically, the restraining cage body 11 is a cage-like structure formed by multiple perforated plates, with one side not having a perforated plate, thus forming an opening. The length of the top perforated plate of the restraining cage body 11 is shorter than the length of the bottom perforated plate, so that the bottom perforated plate extends out of the opening. During animal experiments, animals can be placed into the restraining cage 11 through the opening of the restraining cage body 11. Since breathing masks and other equipment need to be placed over the animal's mouth during experiments, the bottom perforated plate extends out of the opening to allow the animal's mouth to protrude outside the opening, facilitating the placement of breathing masks and other equipment over the animal's mouth by the experimenter, and also providing support for the animal's mouth.

[0042] One end of the rotating plate 5 is rotatably connected to the bottom of the loading platform 2. Specifically, one end of the rotating plate 5 is connected to the loading platform 2 via a rotating shaft. The rotatable connection between the rotating plate 5 and the loading platform 2 is located on the bottom side of the loading platform 2, so as to avoid obstructing the installation of the restraining cage 1 onto the loading platform 2. The other end of the rotating plate 5 is inclined. When the rotating plate 5 rotates, the inclined end can contact the ground, while the other end is still connected to the loading platform 2. Therefore, the rotating plate 5 can serve as a guide surface. When the restraining cage 1 is installed onto the loading platform 2, the moving wheels of the restraining cage 1 can slide on the guide surface, which is convenient for the experimenter to install.

[0043] When the restraining cage 1 is installed on the loading platform 2, taking the installation of the restraining cage 1 on the left side of Figure 1 as an example, the restraining cage 1 is pushed to the right from the end of the loading platform 2, that is, the first sliding groove 1211 of the first limiting member 121 slides along the third limiting member 21. At this time, the first sliding groove 1211 and the third limiting member 21 limit the up and down and front and back directions of the restraining cage 1. When the restraining cage 1 is installed in place, the end of the second limiting member 122 abuts against the end of the third limiting member 21. At this time, the restraining cage 1 can no longer move into the loading platform 2, thus limiting the rightward movement of the restraining cage 1. At this time, the side of the restraining cage with the second limiting member is flush with the side of the loading platform. Then, the rotating plate 5 is rotated so that the side of the rotating plate 5 abuts against the outer side of the restraining cage 1. After abutting, the rotating plate 5 is fixed to the loading platform 2 by the fixing component 6, thus limiting the leftward movement of the restraining cage 1. After the first limiting member 121, the second limiting member 122, the third limiting member 21, the rotating plate 5 and the fixing component 6 limit the holding cage 1, the holding cage 1 is fixed on the loading platform 2.

[0044] Please refer to Figure 5. The fixing component 6 includes a first adapter plate 61, a second adapter plate 62, a handle 63, and a locking member 64. The first adapter plate 61 is disposed on the side of the rotating plate 5, and the handle 63 is rotatably connected to the first adapter plate 61. The second adapter plate 62 is disposed on the side of the loading platform 2, and a latch 621 for connecting with the locking member 64 is provided on the second adapter plate 62. One end of the locking member 64 is connected to the handle 63, and the other end is detachably connected to the latch 621 of the second adapter plate 62. Specifically, the first adapter plate 61 serves as the mounting structure for the handle 63 and can be fixed to the rotating plate 5 by bolts or other means. A rotating shaft can be provided on the first adapter plate 61, and the handle 63 is rotatably connected to the first adapter plate 61 via the rotating shaft. The second adapter plate 62 can be fixed to the carrying platform 2 by bolts or other means. The latch 621 can be a slot provided on the second adapter plate 62. The locking element 64 can be a U-shaped structure, with its open end connected to the middle of the handle 63. When the adapter plate is fixed, the middle of the U-shaped structure is connected to the latch 621, i.e., connected to the slot. After the experiment is completed, rotating the handle 63 removes the locking element 64 from the latch 621, thus releasing the fixation of the prefabricated underwater animal restraint cage 1.

[0045] There are two restraining cages 1, two fixing components 6, and two rotating plates 5. The two restraining cages 1 are symmetrically arranged at one end of the loading platform 2. A rotating plate 5 and a fixing component 6 are arranged in a one-to-one correspondence with one of the restraining cages 1. Specifically, one restraining cage 1 is installed at each end of the loading platform 2, and the two restraining cages 1 are symmetrically arranged after being installed on the loading platform 2. The symmetrical arrangement of the restraining cages 1 facilitates the overall balance of the loading platform 2 after the restraining cages 1 are placed on it, which is convenient for subsequent adjustment by the underwater automatic balancer 4.

[0046] Please refer to Figures 1, 6, and 7. The animal experiment support 3 includes a support body 31 and a camera assembly 32. The loading platform 2 is located at one end of the support body 31. The camera assembly 32 and the load-bearing ring 329 are located at the other end of the support body 31 away from the loading platform 2. The camera assembly 32 includes a third support member, a camera 322, and a camera counterweight 323. The second support member 321 is located on the loading platform 2. One end of the second support member 321 is connected to the camera 322, and the other end is connected to the camera counterweight 323. The camera 322 and the counterweight 323 are located on opposite sides of the support body 31. Specifically, the middle part of the second support member 321 can be fixedly mounted on the bracket body 31. The installation position of the second support member 321 and the bracket body 31 can be located at the center of gravity of the second support member 321, with both ends suspended. One end is connected to the camera counterweight 323, and the other end is connected to the camera 322. That is, the second support member 321 uses the bracket body 31 as a fulcrum to install the camera counterweight 323 and the camera 322. This allows the camera 322 to be installed at a position off-center from the bracket body 31, so that the bubbles generated by the animal's breathing gradually move away from the monitoring screen as they rise, avoiding interference from the real-time monitoring of the underwater animal experiment by the experimental personnel. Furthermore, since the camera 322 is located on one side of the support body 31, and the camera 322 itself has a certain weight, the support body 31 may shift towards the side where the camera 322 is located when underwater, causing the experimental animals to be unable to maintain the appropriate water depth. Therefore, this embodiment introduces a camera counterweight 323, which is set on the opposite side of the support body 31 where the camera 322 is located, to balance the weight of the camera 322 and prevent the support body 31 from shifting towards the side where the camera 322 is installed when underwater. It is understood that the second support member 321 can be a long strip structure, and the camera counterweight 323 can be a structure made of metal or other materials with a certain weight; this embodiment does not impose any restrictions on this.

[0047] In one embodiment, the camera 322 is rotatably connected to the second support member 321. Specifically, the camera assembly 32 further includes a first connector 324, a second connector 325, and a first rotating shaft 326; the camera 322 is mounted on the first connector 324; the second connector 325 is mounted on the second support member 321; the first connector 324 is rotatably connected to the second connector 325 via the first rotating shaft 326. The camera 322 and the first connector 324 can be fixedly mounted, while the second connector 325 and the second support member 321 can also be rotatably mounted, as shown in Figure 6. The angle of the camera 322 in the E direction can be adjusted using the first rotating shaft 326, and the angle in the D direction can also be adjusted using the second connector 325 and the second support member 321, thereby enabling the camera 322 to acquire monitoring images from multiple angles. The first connector 324 can be two mounting plates respectively disposed on both sides of the camera 322. The mounting plates are provided with connecting holes for mounting the first rotating shaft 326, and the first rotating shaft 326 is fixedly connected to the mounting holes. The second connector 325 can be a concave connecting structure, which is connected to the second support 321 and the two connecting plates respectively, and the first rotating shaft 326 and the second connector 325 are rotatably connected.

[0048] Because the size of the experimental animals and their relative positions on the platform 2 vary each time, the position of the animals in the monitoring frame also differs. Therefore, the camera 322 and the second support 321 are rotatably connected. After the experimental animal is placed on the platform 2, the camera 322 can be rotated to ensure that the animal is centered in the frame. In other embodiments, when two experimental animals (i.e., two restraint cages 1) can be placed on the platform 2, adjusting the position of the camera 322 can also ensure that all animals placed on the platform 2 are in the monitoring frame.

[0049] The camera assembly 32 also includes a supplementary light, which is mounted on the first connector 324. The supplementary light and the camera 322 are arranged side by side, and two connectors 422 are respectively connected to the sides of the camera 322 and the supplementary light. The supplementary light is designed to enable the camera 322 to acquire clear images of the experimental animals underwater.

[0050] The camera assembly 32 also includes a snap-fit ​​element 327 and an elastic element 328. A plurality of first mounting holes 3241 are provided on the first connector 324. The plurality of first mounting holes 3241 are arranged symmetrically in a ring on the first connector 324, and their centers are located on the central axis of the first rotating shaft 326. A second mounting hole 3251 is provided on the second connector 3251. The elastic element 328 and the snap-fit ​​element 327 are disposed within the second mounting hole 3251. One end of the elastic element 328 is connected to the bottom of the second mounting hole 3251, and the other end is connected to the snap-fit ​​element 327. The end of the snap-fit ​​element 327 away from the elastic element 328 extends out of the second mounting hole 3251 and connects to the first mounting hole 3241. The snap-fit ​​element 327, the elastic element 328, the first mounting hole 3241, and the second mounting hole 3251 form a snap-fit ​​structure, which is used to maintain the camera 322 in its rotated position. Specifically, there are two first connectors 324, each with multiple first mounting holes 3241, located on opposite sides of each connector 324. There can be multiple second mounting holes 3251, each corresponding to one of the first mounting holes 3241. Alternatively, there can be only one second mounting hole corresponding to one of the first mounting holes 3241; this embodiment does not limit this. The number of snap-fit ​​members 327 and elastic members 328 are arranged in a one-to-one correspondence, and their numbers correspond to the number of second mounting holes 3251. The elastic member 328 can be a spring or an elastic structure made of other materials, preferably a spring. In one embodiment, the end of the snap-fit ​​member 327 away from the elastic member 328 is a non-planar structure, such as an arc shape or a sphere. This non-planar design reduces friction between the snap-fit ​​member 327 and the first connector 324, facilitating the rotation of the camera 322.

[0051] The support body 31 includes a rectangular frame part and a non-rectangular support part; one end of the rectangular frame part is connected to the loading platform 2, and the other end is connected to the non-rectangular support part; the second support member 321 is disposed at the end of the non-rectangular support part away from the rectangular frame part.

[0052] The rectangular frame portion can increase the connection position between the support body 31 and the loading platform 2, ensuring that the loading platform 2 can be stably installed on the support body 31. In addition, the non-rectangular support portion can be a triangular support portion, with the ends away from the rectangular frame portion converging together to facilitate the installation of the second support member 321. Furthermore, it can also facilitate the installation of the load-bearing lifting ring 329 used to hoist the support body 31.

[0053] The camera assembly 32 also includes a third support member, one end of which is connected to the second support member 321, and the other end of which is connected to the rectangular frame. Specifically, the third support member is a long strip structure vertically mounted to the second support member 321, with its end away from the second support member 321 connected to the rectangular frame to support the second mounting component and ensure that the camera 322 and the fill light can be stably mounted on the bracket body 31.

[0054] In other embodiments, the top of the platform 2 is also provided with a compressed air tank for providing oxygen to the breathing mask during the experiment. There are two compressed air pipes, which are symmetrically arranged on the platform 2.

[0055] In summary, this invention, by installing two underwater automatic balancers 4 at the bottom of the platform 2—one for balancing the weight at the front and rear ends of the platform 2, and the other for balancing the weight at the left and right ends—ensures the underwater animal experimental system remains balanced when placed underwater. This allows animals fixed in the restraint cage 1 to be at a specific water depth for accurate experimental data acquisition. Furthermore, by placing the camera 322 on one side of the animal experimental support 3, air bubbles generated by animal respiration can be prevented from affecting the camera's monitoring image. To further maintain the balance of the animal experimental platform, a camera counterweight 323 is also provided on the second support 321 that holds the camera 322, ensuring the underwater experimental system remains balanced. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
