Description

Technical Field

[0036] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0037] See also Figures 1 to 4The utility model provides a protective device for underwater animal experiments, comprising a cover module 11, a mounting base 12 and an opening and closing module 13, wherein the cover module 11 is fixedly mounted on the mounting base 12, and the opening and closing module 13 controls the opening and closing of the cover module 11;

[0038] The cover body module 11 includes a brain cover component 111, an internal organ cover component 112, a buttocks cover component 113, a front cover 114, a rear cover 115, a bottom cover 118, a first partition plate 116 and a second partition plate 117. The brain cover component 111, the internal organ cover component 112, the buttocks cover component 113, the front cover 114, the rear cover 115, the bottom cover 118, the first partition plate 116 and the second partition plate 117 are all provided with an interlayer, which can block the propagation of the vibration signal, thereby protecting the Bama pig from the harm of the vibration signal. The interlayer can be filled with carbon dioxide or set to a vacuum.

[0039] The front cover 114, the brain cover component 111, the viscera cover component 112, the buttocks cover component 113 and the rear cover 115 are sequentially connected from front to back and enclosed with the bottom cover 118 to form a closed protection room. The first partition plate 116 is installed at the connection between the brain cover component 111 and the viscera cover component 112, and the second partition plate 117 is installed at the connection between the viscera cover component 112 and the buttocks cover component 113. The protection room is partitioned into three closed spaces from front to back by the first partition plate 116 and the second partition plate 117. The three closed spaces protect the brain, viscera and buttocks of the Bama pig respectively.

[0040] The opening and closing module 13 drives the brain cover component 111, the internal organs cover component 112 and the buttocks cover component 113 to open and close respectively;

[0041] When it is necessary to detect the damage to the brain of the Bama pig caused by the vibration signal of a certain frequency, the brain cover component 111 is driven to open, and the viscera cover component 112 and the buttocks cover component 113 are kept closed;

[0042] When it is necessary to detect the damage of the internal organs caused by the vibration signal of a certain frequency, the internal organ cover component 112 is driven to open, and the brain cover component 111 is kept closed;

[0043] By analogy, the device can also detect the damage of a Bama pig when the brain and internal organs are protected, but the buttocks and limbs are exposed and attacked by a vibration signal; or when the brain, internal organs and buttocks are all protected, but only the limbs are exposed and attacked by a vibration signal, the damage of a Bama pig;

[0044] A first elastic airbag 1161 is installed in the middle of the first partition plate 116, and a first opening and closing hole 1162 is opened on the first elastic airbag 1161; a second elastic airbag 1171 is installed in the middle of the second partition plate 117, and a second opening and closing hole 1172 is opened on the second elastic airbag 1171. When the Bama pig is loaded into the interior of the protection device, the Bama pig passes through the first opening and closing hole 1162 and the second opening and closing hole 1172. The first elastic airbag 1161 and the second elastic airbag 1171 are filled with carbon dioxide gas, and the absorption effect of carbon dioxide gas on sound waves is stronger than that of nitrogen and oxygen.

[0045] The first elastic airbag 1161 is embedded in the first partition plate 116, and when the Bama pig passes through the first opening and closing hole 1162, the inner circle of the first opening and closing hole 1162 on the first elastic airbag 1161 fits with the neck of the Bama pig;

[0046] The second elastic airbag 1171 is embedded in the second partition plate 117. When the Bama pig passes through the second opening and closing hole 1172, the inner circle of the second opening and closing hole 1172 on the second elastic airbag 1171 fits together with the pig body slightly forward of the base of the hind legs of the Bama pig.

[0047] For this example, please refer to Figure 4 A third elastic airbag 1181 is installed on the bottom cover 118, and a third opening and closing hole 1182 is opened on the third elastic airbag 1181. There are four third elastic airbags 1181, and the four third elastic airbags 1181 are respectively installed on the left and right sides of the middle part of the bottom cover 118 and the left and right sides of the rear part of the bottom cover 118. The third elastic airbag 1181 is still filled with carbon dioxide gas. When the Bama pig is loaded into the device, its limbs extend out of the third opening and closing hole 1182 into the protection room, and the inner circle of the third opening and closing hole 1182 and the limbs of the Bama pig are fitted together. This design is convenient for experimental detection on the one hand, and on the other hand, it also improves the comfort of the Bama pig, which is conducive to the smooth progress of the experiment.
