Description

Technical Field

[0001] The utility model relates to the technical field of small animal living cabins, in particular to a high-pressure device suitable for small animals to live in for a long time. Background Art

[0002] When conducting long-term experiments on small animals under high-pressure environments, the small animals need to be placed in a high-pressure chamber for the experiment. The existing high-pressure chambers are not conducive to the long-term living and living security of small animals. First, when small animals stay in the hyperbaric chamber for a long time, urine, feces and other dirt will be produced. These dirt cannot be removed from the hyperbaric chamber in time, resulting in the deterioration of the living environment of the small animals, and even causing infection of the small animals, thus leading to the failure of the experiment; second, when small animals are placed in animal carrying cages, there will be dirt at the bottom of the animal carrying cages where the small animals stand or lie, which cannot be cleaned in time, resulting in the deterioration of the living environment of the small animals, etc., and the living environment of the small animals cannot be guaranteed; third, the existing method generally is to directly spread a certain amount of carbon dioxide absorbent in the hyperbaric chamber, and the quantity is limited. The carbon dioxide absorbent cannot be replaced in time after use, which is not conducive to the long-term living and living guarantee of the small animals. Moreover, the existing method can only absorb the carbon dioxide in the living environment of the small animals, and cannot realize the adsorption of other impurities in the living environment of the small animals, and cannot provide the small animals with a relatively clean living environment; fourth, the existing method generally is to pre-place a certain amount of food and water in the hyperbaric chamber for the small animals to eat. Since the small animals can eat at will, the food and water are quickly consumed and cannot be replenished in time, which is not conducive to the long-term living and living guarantee of the small animals.

The specific structures, circuit designs and working principles of the third electrically controlled valve 33, the fourth electrically controlled valve 35, the fifth electrically controlled valve 37, the sixth electrically controlled valve 39, the seventh electrically controlled valve 504, the first pressure sensor 505, the high-pressure water pump 509, the eighth electrically controlled valve 510, the electric push rod 511, the pressure relief electrically controlled valve, the second pressure sensor 62, the ninth electrically controlled valve 64, the third pressure sensor 72 and the tenth electrically controlled valve 74 and the controller are all publicly available technologies. The specification only uses these electronic components to achieve certain functions. There is no need to describe in detail the specific structures, circuit designs and working principles of these existing electronic components, and the entire solution is clear.

[0024] The air purification process is as follows: the off-board controller is used to control the off-board air purification mechanism 40 to purify the air in the high-pressure cabin 100. Specifically, the off-board controller is used to control the first electric control valve 416 and the second electric control valve 417 to open at the beginning of the long-term residence of the small animal, so that the polluted air in the high-pressure cabin 100 flows into the tank 401 through the polluted air circulation pipe 404, and the polluted air is sequentially filtered by the primary filter 411, the high-efficiency filter 412, and the lower absorption strip 413 is absorbed by water vapor before entering the oxygen production chamber 409. The carbon dioxide in the gas after the water vapor absorption reacts chemically with the oxygen generator in the oxygen production chamber 409 to produce oxygen, and the carbon dioxide in the gas that does not react chemically with the oxygen generator enters the absorption chamber 410 and is absorbed by the carbon dioxide absorbent. The gas absorbed by the carbon dioxide absorbent is absorbed by the upper water absorption strip 414 and then flows into the high-pressure cabin 100 through the clean air circulation pipe 405. Through the continuous cycle of the above operations, the off-board air purification mechanism 40 can purify the air in the high-pressure cabin 100.

[0025] This solution can effectively remove pollutants such as particulate matter, aerosols, dust, wet steam, animal metabolites, etc. in the hyperbaric cabin, purify the air in the cabin, and chemically react the carbon dioxide in the polluted gas with the oxygen generator to produce oxygen. The carbon dioxide that has not chemically reacted with the oxygen generator enters the absorption chamber and is absorbed by the carbon dioxide absorbent, turning carbon dioxide into treasure and providing clean gas for the hyperbaric cabin.

[0026] The offboard controller is also used to control the first electric control valve 416 and the second electric control valve 417 to close, and at the same time control the issuance of a reminder message for replacement when the temperature value detected by the received temperature sensor 415 reaches a preset temperature value, indicating that the carbon dioxide absorbent in the tank body 401 is about to be used up and the agent in the tank body 401 needs to be replaced. After hearing the reminder, the staff unscrewed the tank cover 402, took out the upper water absorption strip 414, the third porous partition 408, the carbon dioxide absorbent, the second porous partition 407, the oxygen generator, the first porous partition 406, the lower water absorption strip 413, the high-efficiency filter 412 and the primary filter 411 in turn, replaced them with new ones, and put in the primary filter 411, the high-efficiency filter 412, the lower water absorption strip 413, the first porous partition 406, the oxygen generator, the second porous partition 407, the carbon dioxide absorbent, the third porous partition 408 and the upper water absorption strip 414 from bottom to top, and then tightened the tank cover 402. At this time, the new one in the tank body has been replaced, and then the first electric control valve 416 and the second electric control valve 417 are controlled to open to continue air purification in the high-pressure chamber.

[0027] The high-pressure air supply process is as follows: the outboard controller is used to control the outboard high-pressure air supply mechanism 30 to supply air to the high-pressure cabin 100 so that the pressure value in the high-pressure cabin 100 detected by the cabin pressure sensor 20 is maintained within the set high-pressure range. Specifically, the outboard controller is used to control the third electric control valve 33 to open, and the high-pressure gas in the high-pressure gas tank 31 flows into the high-pressure cabin 100 through the first ventilation pipe 32 to supply air to the high-pressure cabin 100, and receives the pressure value in the high-pressure cabin 100 detected by the cabin pressure sensor 20. When the pressure value is not within the set high-pressure range, the controller continues to supply air until the pressure value is within the set high-pressure range. At this time, the controller controls the third electric control valve 33 to close, so as to maintain the pressure value in the high-pressure cabin 100 within the set high-pressure range.

[0028] The waste flushing and collection process is as follows: the outboard controller is used to control the outboard high-pressure air supply mechanism 30 to supply air to the outboard waste flushing and collection mechanism 50, so that the pressure value in the channel of the outboard waste flushing and collection mechanism 50 is consistent with the pressure value in the high-pressure cabin 100, and then controls the outboard waste flushing and collection mechanism 50 to flush and collect the waste generated by the small animals. Specifically, the off-board controller is used to control the fourth electrically controlled valve 35 to open at set time intervals, so that the high-pressure gas in the high-pressure gas tank 31 enters the waste collection bucket 503 through the second ventilation pipe 34 to pressurize the waste collection bucket 503 until the pressure value detected by the first pressure sensor 505 is the same as the pressure value detected by the pressure sensor 20 in the cabin. At this time, the fourth electrically controlled valve 35 is controlled to close, and the electric push rod 511 is controlled to start, pushing the L-shaped supporting plate 512 to move to the left side of the animal supporting cage 11, so that the small animal placed on the animal supporting hollow frame 12 is placed on the horizontal supporting plate of the L-shaped supporting plate 512, and then the seventh electrically controlled valve 504 and the eighth electrically controlled valve 510 are controlled to open, and the high-pressure water pump 506 is controlled to open. 09 is turned on and the timing starts. The high-pressure water pump 509 pumps the high-pressure water in the high-pressure water tank 508 through the flushing water pipe 507 and the flushing water channel in turn, and then pumps it out from the flushing hole 506 to the animal carrying hollow frame 12 to flush the animal carrying hollow frame 12 and the dirt funnel 501. The dirt on the animal carrying hollow frame 12 and the dirt in the dirt funnel 501 flow into the dirt collecting barrel 503 through the dirt connecting pipe 502. When the timing reaches the set flushing time, the seventh electric control valve 504 and the eighth electric control valve 510 are controlled to close, the high-pressure water pump 509 is paused, and the electric push rod 511 is reset. At this time, the small animals are placed on the cleaned animal carrying hollow frame 12, so that the living environment of the small animals remains relatively clean.

[0029] The outboard controller is used to control the pressure relief electric control valve to open after the set waste removal time is reached, so that the high-pressure gas in the waste collection bucket 503 is discharged through the exhaust pipe until the pressure value detected by the first pressure sensor 505 is normal pressure, at which time the pressure relief electric control valve is controlled to close, and the staff is provided with the waste collection bucket 503. The staff removes the bottom of the waste connecting pipe 502 and the right end of the second ventilation pipe 34, removes the waste collection bucket 503, and replaces it with a new waste collection bucket 503. The bottom of the waste connecting pipe 502 is inserted into the waste collection bucket 503, and the insertion position is sealed. The right end of the second ventilation pipe 34 is inserted into the waste collection bucket 503, and the insertion position is sealed.

[0030] The food supply process is as follows: the outboard controller is used to control the outboard high-pressure air supply mechanism 30 to supply air to the outboard feeding mechanism 60, so that the pressure value in the channel of the outboard feeding mechanism 60 is consistent with the pressure value in the high-pressure cabin 100, and then the outboard feeding mechanism 60 is controlled to provide food to the small animals. Specifically, the outboard controller is used to control the fifth electric control valve 37 to open when the set feeding time is reached, and the high-pressure gas in the high-pressure gas tank 31 enters the outboard feeding box 60 through the third ventilation pipe 36 to pressurize the outboard feeding box 60, and when the pressure value detected by the second pressure sensor 62 is the same as the pressure value detected by the inboard pressure sensor 20, the fifth electric control valve 37 is controlled to close, and the ninth electric control valve 64 is controlled to open and time, and the food in the outboard feeding box 61 flows into the feeding bowl 13 through the feeding pipe 63 for the small animals to eat, and when the timer reaches the set feeding time, the ninth electric control valve 64 is controlled to close.

[0031] The water supply process is as follows: the outboard controller is used to control the outboard high-pressure air supply mechanism 30 to supply air to the outboard water supply mechanism 70, so that the pressure value in the channel of the outboard water supply mechanism 70 is consistent with the pressure value in the high-pressure cabin 100, and then the outboard water supply mechanism 70 is controlled to provide water to the small animals. Specifically, the outboard controller is used to control the sixth electric control valve 39 to open when the set water supply time is reached, and the high-pressure gas in the high-pressure gas tank 31 enters the outboard water supply tank 71 through the fourth ventilation pipe 38 to pressurize the outboard water supply tank 71, and when the pressure value detected by the third pressure sensor 72 is the same as the pressure value detected by the inboard pressure sensor 20, the sixth electric control valve 39 is controlled to close, and the tenth electric control valve 74 is controlled to open and time, and the water in the outboard water supply tank 71 flows into the water supply basin 14 through the water supply pipe 73 for the small animals to drink, and when the timer reaches the set water supply time, the tenth electric control valve 74 is controlled to close.
