Description

Technical Field

[0001] The utility model belongs to the technical field of underwater animal experiments in diving medicine, and particularly relates to an underwater automatic balancer and an underwater animal experiment device Background Art

[0002] Diving medicine, also known as underwater medicine, is a discipline that studies and solves various medical problems in the process of diving operations, including studying the physiological reactions and pathological changes of organisms during labor operations in underwater and high-pressure environments, the prevention and treatment of diving diseases, the hygienic requirements and medical protection technical measures in diving operations, etc. In the process of studying diving medicine, animal experiments are usually carried out first, and then it can be transitioned to human experiments

[0003] When conducting underwater animal experiments, animals are usually fixed on a holding cage, and then the holding cage is placed into an underwater animal experiment device. At the same time, a monitor for detecting the physiological characteristics of the animals and a breathing mask for maintaining the vital signs of the animals are placed over the mouths of the animals. After completing the above operations, the entire underwater animal experiment device is placed underwater and immersed to a certain depth underwater for experiments

[0004] Due to factors such as the different fixing positions when fixing animals to the holding cage, when the underwater animal experiment device is placed underwater, the underwater animal experiment device will tilt towards the heavier end, resulting in the animals being tilted relative to the horizontal plane underwater, causing different parts of the animals' bodies to be at different water depths, and making it impossible to accurately obtain experimental data of the animals at the corresponding water depths. Therefore, the traditional method is to lift the underwater animal experiment device with an electric hoist or a crane before placing it underwater, and manually add counterweights to the lighter side of the underwater animal experiment device to ensure that the two ends are on the same horizontal plane before the underwater animal experiment device is placed underwater

[0005] However, the traditional method is to perform counterweight leveling in the air before the underwater animal experiment device is placed underwater. However, when placed underwater, due to the different drainage volumes of the animals, monitors, or compressed air tanks of the breathing masks on the underwater animal experiment device, the underwater animal experiment device will tilt towards the end with a smaller drainage volume when placed underwater, resulting in the inability to accurately obtain experimental data of the animals at the corresponding water depths Summary of the Utility Model

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present utility model.

[0025] The following various embodiments are only for illustration purposes. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiment only.

[0026] Please refer to Figure 1-2, the present utility model provides an underwater automatic balancer 10, which includes a support member 1, a counterweight assembly 2, a drive assembly 3, a power-on assembly 4, and a distribution box; the drive assembly 3, the counterweight assembly 2, and the power-on assembly 4 are arranged on the support member 1; there are two counterweight assemblies 2 and two drive assemblies 3 respectively. One counterweight assembly 2 is arranged at each end of the support member 1, and the drive assembly 3 and the counterweight assembly 2 are arranged in one-to-one correspondence; the drive assembly 3 is used to drive the counterweight assembly 2 to move along the support member 1; the power-on assembly 4 is arranged between the two counterweight assemblies 2; the power-on assembly 4 includes a first accommodation cavity 41, a conductive member 42, and four electrodes 43; the first accommodation cavity 41 is arranged on the support member 1; two electrodes are arranged at each end of the first accommodation cavity 41. One of the two electrodes arranged at one end of the first accommodation cavity 41 is connected to the distribution box, and the other electrode is connected to the drive assembly 3; the conductive member 42 is movably arranged in the first accommodation cavity 41. When the conductive member 42 moves to one end of the first accommodation cavity 41, it is used to conduct the two electrodes arranged on the first accommodation cavity 41. The first accommodation cavity 41 can be arranged inside the support member 1. Specifically, a groove for accommodating the electrodes and the conductive member 42 is opened on the support member 1. After the 4 electrodes and the conductive member 42 are arranged in the groove, the opening of the groove is covered by a cover plate to realize the arrangement of the electrodes and the conductive member 42 in the groove and achieve sealing, preventing water from entering the groove and affecting the electrical connection between the conductive member 42 and the electrodes. It can be understood that there is a clearance fit between the conductive member 42 and the groove, so as to realize the sliding of the conductive member 42 in the groove. In addition, the groove can be arranged at the central position of the support member 1, so that the weights of the two counterweight assemblies 2 can be set to be the same, that is, the counterweight assemblies 2 can be produced in batches, reducing production costs. The 4 electrodes are divided into two groups, and the two groups of electrodes are symmetrically arranged on the side surface of the groove. One of each group of electrodes is connected to the distribution box, and the other is connected to the drive assembly 3. When the support member 1 is inclined, the conductive member 42 slides towards the lower end of the support member 1 by gravity. Then the conductive member 42 is respectively connected to the two electrodes at the lower end, so as to realize the transmission of the power on the distribution box to the drive assembly 3 through the electrodes. After the drive assembly 3 is powered on, it drives the counterweight assembly 2 at the lower end to move towards the middle of the support member 1, that is, towards the direction close to the conductive member 42, so that the support member 1 gradually becomes flush with the horizontal plane. When the support member 1 is flush with the horizontal plane, the conductive member 42 is at the middle position of the first accommodation cavity 41, that is, at this time, the conductive member 42 is not in contact with either group of electrodes, and neither of the two drive assemblies 3 is powered on, and the relative position of the counterweight assembly 2 and the support member 1 will not change. The distribution box can be arranged on the loading platform 6 of the underwater animal experiment device 20, or can also be arranged on the support member 1 and located between the two counterweight assemblies 2. The present utility model does not limit this. It can be understood that the distribution box, the electrodes, and the electrodes and the drive assembly 3 can be electrically connected through cables.

[0027] The conductive member 42 can be made of a conductive material, or a wrapping layer made of a conductive material can be wrapped around the outer side of the conductive member 42. The present utility model does not limit this. In this embodiment, the conductive member 42 is a spherical structure, so as to reduce the friction between the conductive member 42 and the side wall of the first accommodating cavity 41 and improve the sensitivity of the energizing assembly 4; and when the conductive member 42 moves in the first accommodating cavity, it will cause a certain amount of wear on the side surface of the first accommodating cavity and the conductive member 42. By setting it as a spherical structure, its rolling characteristics can be utilized to avoid the situation where the wear amount of the conductive member is concentrated on one side, resulting in the inability of the conductive member to contact the electrode, and increasing the service life of the underwater automatic balancer. More specifically, in this embodiment, the conductive member 42 is a metal ball. Of course, in other embodiments, the conductive member 42 can also be of other shapes. The present utility model does not limit this, as long as each group of electrodes can be electrically connected.

[0028] The underwater automatic balancer 10 further includes a water-sensitive switch 5. The water-sensitive switch 5 is arranged on the support member 1. One end of the water-sensitive switch 5 is connected to the distribution box, and the other end is connected to the electrode connected to the distribution box; or one end of the water-sensitive switch 5 is connected to the driving assembly 3, and the other end is connected to the electrode connected to the driving assembly 3. The water-sensitive switch 5 is a switch device that can detect 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 closing the operation of the circuit controller, and realizing precise positioning and control of changes in water flow or water level. Specifically, two water-sensitive switches are provided, and one water-sensitive switch corresponds to one driving assembly 3. Through the setting of the water-sensitive switch 5, when the underwater automatic balancer 10 is in the air, the water-sensitive switch 5 automatically disconnects the electrical connection between the distribution box and the electrode or between the electrode and the driving assembly 3, avoiding the situation where the conductive member 42 drives the driving assembly 3 to move during the transportation or installation of the underwater automatic balancer 10, and further driving the counterweight assembly 2 to move. When the underwater automatic balancer 10 is underwater, the water-sensitive switch 5 automatically restores the electrical connection between the distribution box and the electrode or between the electrode and the driving assembly 3. At this time, the connection between the conductive member 42 and each group of electrodes can make the balancer parallel to the horizontal plane.

[0029] The driving assembly 3 includes a driving member 31 and a transmission member 32. The driving assembly 3 and the transmission member 32 are arranged on the support member 1. The driving member 31 is connected to the electrode; one end of the transmission member 32 is connected to the driving member 31, and the other end is connected to the counterweight assembly 2. The driving member 31 serves as a power output member to drive the transmission member 32 to move, and further drive the counterweight assembly 2 to move on the support member 1, so that the balancer is parallel to the horizontal plane. The driving member 31 can be a power output member such as a motor or a cylinder. In this embodiment, the driving member 31 is a motor.

[0030] The driving members 31 of the two driving assemblies 3 are respectively arranged on opposite side surfaces of the support member 1. Specifically, as Figure 1As shown, one driving member 31 is arranged on the front side surface of the support member 1, and the other driving member 31 is arranged on the rear side surface of the support member 1. It can be understood that since the driving member 31 has a certain weight, if the two driving members 31 are arranged on the front side surface at the same time, or on the rear side surface, due to the gravity of the driving member 31, the balancer will tilt towards the side where the two driving members 31 are arranged. In addition, in other embodiments, the driving member 31 can be arranged on the upper side surface and the lower side surface of the support member 1 at the same time, or one driving member 31 is arranged on the upper side surface and the other is arranged on the lower side surface; since the driving member 31 is arranged on the upper side surface and the lower side surface at the same time, or one driving member 31 is arranged on the upper side surface and the other is arranged on the lower side surface, the weights on the front and rear sides of the support member 1 can be kept consistent, so the balancer will not tilt towards the front side surface or the rear side surface.

[0031] The counterweight assembly 2 includes a counterweight member 21 and a connecting member 22; the connecting member 22 is sleeved on the support member 1, and the connecting member 22 is slidably connected to the support member 1, and the counterweight member 21 is connected to the transmission member 32 through the connecting member 22. Specifically, the connecting member 22 can be provided with a through hole matching the shape of the support member 1, and the connecting member 22 is sleeved on the support member 1 by using the through hole, and the sliding connection can be realized by using the surface contact between the through hole and the support member 1. The counterweight member 21 can be of a cylindrical or square structure, and the connecting member 22 is arranged at the center of gravity of the counterweight member 21 to ensure that the balancer will not tilt due to the inconsistent weights of the counterweight member 21 on the front side surface and the rear side surface of the support member 1.

[0032] A second receiving cavity 11 can be arranged on the support member 1, and the transmission member 32 is arranged in the second receiving cavity 11; specifically, the second receiving cavity 11 can be a groove arranged on the support member 1, and of course it can also be other structures, and this embodiment does not limit this. The transmission shaft of the driving member 31 can extend into the second receiving cavity 11 to be connected to the transmission member 32. The connection structure between the connecting member 22 and the transmission member 32 can also extend into the receiving cavity to be connected to the transmission member 32. The second receiving cavity 11 serves as a receiving structure for receiving the transmission member 32 to prevent interference between the transmission member 32 and the connecting member 22.

[0033] The driving assembly 3 further includes a first pulley 33 and a second pulley 34; the first pulley 33 is arranged at one end of the second receiving cavity 11, and the second pulley 34 is arranged at the end of the second receiving cavity 11 away from the first pulley 33; the transmission member 32 is sleeved on the first pulley 33 and the second pulley 34; the first pulley 33 is connected to the driving member 31, and the transmission member 32 is a belt. Specifically, the connection structure between the connecting member 22 and the transmission member 32 is arranged on the suspended section of the belt, and the driving member 31 is connected to the first pulley 33 for driving the first pulley 33 to rotate.

[0034] A limiting member 12 for restricting the movement distance of the counterweight assembly 2 is further provided on the support member 1. Specifically, the limiting member 12 may be a limiting block provided on the support member 1, and the number may be 4, which are respectively arranged corresponding to the first pulley 33 and the second pulley 34, that is, as a mechanical limit to restrict the movement distance of the connecting member 22 on the support member 1.

[0035] Please refer to Figure 3 , the present invention also provides an underwater animal experiment device 20, including a load platform 6 and the above-mentioned underwater automatic balancer 10; the underwater automatic balancer 10 is arranged on the load platform 6. Specifically, the load platform 6 serves as an installation structure for installing a compressed air tank and an animal restraint cage; the underwater automatic balancer 10 can be arranged at the bottom of the load platform 6. When the underwater animal experiment device 20 is placed in water, the underwater automatic balancer 10 contacts the water surface first. As the underwater animal experiment device 20 is further placed underwater, due to the different drainage volumes of the animals in the animal restraint cage or the compressed air tank, etc., the underwater animal experiment device 20 tilts to one side. At this time, the conductive member 42 of the underwater balancer slides towards the lower end after tilting, so that the corresponding drive assembly 3 is electrically connected to the distribution box, and then drives the counterweight assembly 2 to move, so that the underwater animal experiment device 20 is in a horizontal state.

[0036] In summary, the present invention provides an underwater automatic balancer 10 and an underwater animal experiment device 20. By respectively arranging a counterweight assembly 2, a drive assembly 3, a conductive member 42 movably arranged in a second accommodation cavity 11 located between the two counterweight assemblies 2, and two electrodes are respectively arranged at both ends of the second accommodation cavity 11, one of the electrodes is connected to the distribution box, and the other electrode is connected to the drive assembly 3. When the balancer is in an inclined state, the conductive member 42 moves in the second accommodation cavity 11 by gravity to conduct the electrical connection between the drive assembly 3 at the lower end of the balancer and the distribution box, so as to drive the counterweight assembly 2 at the lower end to approach the conductive member 42, and then realize the automatic horizontal state of the underwater automatic balancer 10. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0037] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
