Description

Technical Field

[0001] The present invention relates to the technical field of small animal living cabin environment control, in particular to a control system for ensuring the long-term living of small animals in a high-pressure environment. 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. 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, they will produce urine, feces and other dirt. 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 infection of the small animals, which leads 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 are standing or lying, 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 places a certain amount of carbon dioxide absorbent directly 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 security of the small animals. Moreover, the existing method can only absorb carbon dioxide in the living environment of the small animals, and cannot achieve 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 places a certain amount of food and water in the hyperbaric chamber in advance 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 security of the small animals. Summary of the Invention

[0003] In view of the problems and shortcomings of the prior art, the present invention provides a control system for ensuring the long-term living of small animals in a high-pressure environment.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a control system for ensuring the long-term living of small animals in a high-pressure environment. The control system comprises an in-cabin animal carrying mechanism and an in-cabin pressure sensor located in a high-pressure cabin for carrying small animals, and an out-cabin high-pressure control mechanism, an out-cabin air purification control mechanism, an out-cabin waste flushing and collection control mechanism, an out-cabin feeding control mechanism, an out-cabin water supply control mechanism, and an out-cabin controller located outside the high-pressure cabin. The out-cabin high-pressure control mechanism is connected and communicated with the high-pressure cabin, the out-cabin waste flushing and collection control mechanism, the out-cabin feeding control mechanism, and the out-cabin water supply control mechanism, respectively. The out-cabin air purification control mechanism is connected and communicated with the high-pressure cabin. The out-cabin waste flushing and collection control mechanism is located directly below the in-cabin animal carrying mechanism and is connected and communicated with the in-cabin animal carrying mechanism. The out-cabin feeding control mechanism is located directly above the in-cabin animal carrying mechanism and is connected and communicated with the in-cabin animal carrying mechanism. The out-cabin water supply control mechanism is located directly above the in-cabin animal carrying mechanism and is connected and communicated with the in-cabin animal carrying mechanism.

[0006] The outboard controller is used to control the outboard high-pressure control mechanism to supply air to the high-pressure cabin so that the pressure value inside the high-pressure cabin detected by the inboard pressure sensor is maintained within a set high-pressure range;

[0007] The off-board controller is used to control the off-board air purification control mechanism to purify the air in the high-pressure cabin;

[0008] The off-board controller is used to control the off-board high-pressure control mechanism to supply air to the off-board waste flushing and collection control mechanism so that the pressure value in the channel of the off-board waste flushing and collection control mechanism is consistent with the pressure value in the high-pressure chamber, and then control the off-board waste flushing and collection control mechanism to flush and collect waste generated by the small animals;

[0009] The off-board controller is used to control the off-board high-pressure control mechanism to supply air to the off-board feeding control mechanism so that the pressure value in the channel of the off-board feeding control mechanism is consistent with the pressure value in the high-pressure chamber, and then control the off-board feeding control mechanism to provide food to the small animals;

[0010] The outboard controller is used to control the outboard high-pressure control mechanism to supply air to the outboard water supply control mechanism so that the pressure value in the channel of the outboard water supply control mechanism is consistent with the pressure value in the high-pressure cabin, and then controls the outboard water supply control mechanism to provide water to the small animals.

[0011] The positive progress effect of the present invention is:

[0012] In the present invention, pollutants such as particulate matter, aerosols, dust, wet steam, animal metabolic products, etc. in the high-pressure cabin can be effectively removed to achieve cabin air purification, and part of the carbon dioxide can be converted into oxygen to supply air to the high-pressure cabin. The outdoor air purification control mechanism is placed outside the high-pressure cabin, which is convenient for replacing the filter screen, water absorption strip, oxygen generator and carbon dioxide absorber therein, which is beneficial to the long-term living and living security of small animals in a high-pressure environment.

[0013] In the present invention, the small animal carrying area is cleaned regularly, and the cleaned dirt and the dirt in the dirt funnel flow into the dirt collection bucket together, and the staff is notified to take them away, thereby greatly reducing the deterioration of the environment in the hyperbaric chamber, keeping the hyperbaric chamber relatively clean, and being conducive to the long-term living and living security of small animals in a high-pressure environment.

[0014] In the present invention, food and water are provided to the small animals in the hyperbaric chamber at regular intervals, and the extra-cabin food supply control mechanism and the extra-cabin water supply control mechanism are arranged outside the hyperbaric chamber, which makes it convenient for staff to add food and water, and is beneficial to the long-term living security of the small animals in the hyperbaric environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a structural diagram of a control system for ensuring the long-term living of small animals in a high-pressure environment according to a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0017] like Figure 1 As shown, this embodiment provides a life support control system for small animals living long-term in a high-pressure environment, which includes an in-cabin animal carrying mechanism 10 and an in-cabin pressure sensor 20 for carrying small animals located in a high-pressure cabin 100, as well as an out-cabin high-pressure control mechanism 30, an out-cabin air purification control mechanism 40, an out-cabin waste flushing and collection control mechanism 50, an out-cabin feeding control mechanism 60, an out-cabin water supply control mechanism 70 and an out-cabin controller located outside the high-pressure cabin 100. In addition, the high-pressure cabin 100 is supported by multiple support columns 80 located at the bottom.

[0018] The outside high-pressure control mechanism 30 is respectively connected to the high-pressure cabin body 100, the outside waste flushing and collection control mechanism 50, the outside feeding control mechanism 60 and the outside water supply control mechanism 70. The outside air purification control mechanism 40 is connected to the high-pressure cabin body 100. The outside waste flushing and collection control mechanism 50 is located directly below the animal carrying mechanism 10 in the cabin and is connected to the animal carrying mechanism 10 in the cabin. The outside feeding control mechanism 60 is located directly above the animal carrying mechanism 10 in the cabin and is connected to the animal carrying mechanism 10 in the cabin. The outside water supply control mechanism 70 is located directly above the animal carrying mechanism 10 in the cabin and is connected to the animal carrying mechanism 10 in the cabin.

[0019] Among them, the animal carrying mechanism 10 in the cabin includes an animal carrying cage 11 with an opening at the bottom. The animal carrying cage 11 is fixed in the high-pressure cabin body 100. Directly below the bottom opening of the animal carrying cage 11 is a through hole opened at the bottom of the high-pressure cabin body 100. An animal carrying hollow frame 12 for carrying small animals is fixed in the through hole, and the small animals move on the animal carrying hollow frame 12.

[0020] The extravehicular air purification control mechanism 40 includes an air purification tank, which includes a tank body 401 and a tank cover 402 located on the top of the tank body 401. The tank body 401 and the tank cover 402 are screwed together. A plurality of bottom columns 403 are fixed to the bottom of the tank body 401 to support the tank body 401. The middle position of the inner bottom of the tank body 401 is connected to the high-pressure cabin body 100 through a contaminated air circulation pipe 404, and the middle position of the inner top of the tank cover 402 is connected to the high-pressure cabin body 100 through a clean air circulation pipe 405. The first porous partition 406, the second porous partition 407 and the third porous partition 408 are sequentially placed in the tank body 401 from bottom to top. The inner cavity between the bottom of the tank body 401 and the first porous partition 406 is provided with a filtration cavity and a lower water absorption cavity from bottom to top. The inner cavity between the first porous partition 406 and the second porous partition 407 constitutes an oxygen production cavity 409, the inner cavity between the second porous partition 407 and the third porous partition 408 constitutes an absorption cavity 410, and the inner cavity between the third porous partition 408 and the top of the tank body 401 constitutes an absorption cavity 411. The inner cavity between the tank body and the outer surface of the tank body constitutes an upper water absorption chamber, and the filter chamber is provided with a primary filter screen 411 and a high-efficiency filter screen 412 from bottom to top, a lower water absorption strip 413 is placed in the lower water absorption chamber, an oxygen generating agent is placed in the oxygen producing chamber 409, a carbon dioxide absorbent is placed in the absorption chamber 410, and an upper water absorption strip 414 is placed in the upper water absorption chamber. A temperature sensor 415 is fixed near the top of the tank body 401, a first electric-controlled valve 416 is provided on the polluted air circulation pipe 404, and a second electric-controlled valve 417 is provided on the clean air circulation pipe 405.

[0021] The pore size of the first porous partition 406 prevents the oxygen generator from passing through, the pore size of the second porous partition 407 prevents both the oxygen generator and the carbon dioxide absorbent from passing through, and the pore size of the third porous partition 408 prevents the carbon dioxide absorbent from passing through.

[0022] The air purification control principle is as follows: the off-board controller is used to control the off-board air purification control mechanism 40 to purify the air inside the high-pressure cabin 100 . Specifically, the off-board controller is used to control the opening of the first electrically controlled valve 416 and the second electrically controlled valve 417 at the beginning of the long-term residence of the small animals, so that the polluted air in the high-pressure cabin 100 flows into the tank body 401 through the polluted air circulation pipe 404. The polluted air is sequentially filtered through the primary filter 411, filtered through the high-efficiency filter 412, and absorbed by the lower absorption strip 413 before entering the oxygen production chamber 409. The carbon dioxide in the gas after water vapor absorption chemically reacts with the oxygen generator in the oxygen production chamber 409 to produce oxygen. The carbon dioxide in the gas that has not chemically reacted 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 water vapor through 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 control mechanism 400 can purify the air in the high-pressure cabin 100.

[0023] This solution can effectively remove pollutants such as particulate matter, aerosols, dust, wet steam, and animal metabolites in the hyperbaric chamber, purify the air in the chamber, and chemically react the carbon dioxide in the polluted gas with the oxygen generator to produce oxygen. The carbon dioxide that does not chemically react 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 chamber.

[0024] The offboard controller is also used to control the first electrically controlled valve 416 and the second electrically controlled valve 417 to close 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. At this time, the controller controls the first electrically controlled valve 416 and the second electrically controlled valve 417 to close, and at the same time controls the issuance of a reminder message for replacement. 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.

[0025] The extravehicular high-pressure control mechanism 30 includes a high-pressure gas tank 31, which is connected to the high-pressure cabin body 100 through a first ventilation pipe 32, and a third electrically controlled valve 33 is provided on the first ventilation pipe 32. The high-pressure gas tank 31 is connected to the extravehicular waste flushing and collection control mechanism 50 through a second ventilation pipe 34, and a fourth electrically controlled valve 35 is provided on the second ventilation pipe 34. The high-pressure gas tank 31 is connected to the extravehicular food supply control mechanism 60 through a third ventilation pipe 36, and a fifth electrically controlled valve 37 is provided on the third ventilation pipe 36. The high-pressure gas tank 31 is connected to the extravehicular water supply control mechanism 70 through a fourth ventilation pipe 38, and a sixth electrically controlled valve 39 is provided on the fourth ventilation pipe 38.

[0026] The high-pressure control principle is as follows: the offboard controller controls the offboard high-pressure control mechanism 30 to supply air to the high-pressure chamber 100 so that the pressure value within the high-pressure chamber 100, as detected by the inboard pressure sensor 20, remains within a set high-pressure range. Specifically, the offboard controller controls the third electrically controlled valve 33 to open, allowing high-pressure gas from the high-pressure gas tank 31 to flow into the high-pressure chamber 100 through the first vent pipe 32, thus supplying air to the high-pressure chamber 100. The offboard controller receives the pressure value within the high-pressure chamber 100 detected by the inboard pressure sensor 20 and continues to supply air if the pressure value is not within the set high-pressure range until it is within the set high-pressure range. At this point, the controller controls the third electrically controlled valve 33 to close, thereby maintaining the pressure value within the high-pressure chamber 100 within the set high-pressure range.

[0027] The control mechanism 50 for flushing and collecting waste outside the cabin includes a waste funnel 501, which is fixed to the outside of the bottom of the high-pressure cabin 100 and is located directly below the animal-carrying hollow frame 12. The top length of the waste funnel 501 is greater than or equal to the length of the animal-carrying hollow frame 12. The bottom of the waste funnel 501 is connected to the waste collection bucket 503 through a waste connecting pipe 502. A seventh electric-controlled valve 504 is provided on the waste connecting pipe 502. A first pressure sensor 505 is provided on the waste connecting pipe 502 and below the seventh electric-controlled valve 504. The wall of the waste funnel 501 is provided with a first pressure sensor 505. A flushing water channel is opened along the circumferential direction inside, and a plurality of flushing holes 506 are opened along the circumferential direction on the inner wall of the dirt funnel 501. Each flushing hole 506 is connected to the flushing water channel, and the flushing water channel is connected to one end of the flushing water pipe 507. The other end of the flushing water pipe 507 is inserted into the high-pressure water tank 508. A high-pressure water pump 509 and an eighth electric-controlled valve 510 are provided on the flushing water pipe 507. The top of the dirt collection barrel 503 is connected to the high-pressure gas tank 31 through the second ventilation pipe 34. The top of the dirt collection barrel 503 is externally connected to an exhaust pipe, and a pressure relief electric-controlled valve is provided on the exhaust pipe.

[0028] The extra-cabin waste flushing and collection control mechanism 50 also includes an electric push rod 511, which is fixed to the outside of the high-pressure cabin body 100. A high-pressure sealing ring is clamped at the fixed position between the electric push rod 511 and the high-pressure cabin body 100. The push rod end of the electric push rod 511 passes through the high-pressure cabin body 100 and is placed inside the high-pressure cabin body 100. An L-shaped supporting plate 512 is fixed to the push rod end of the electric push rod 511. A gap is left between the horizontal supporting plate of the L-shaped supporting plate 512 and the animal supporting hollow frame 12. In the initial state, the end of the horizontal supporting plate of the L-shaped supporting plate 512 just passes through the right side of the animal supporting cage 11.

[0029] The principle of waste flushing and collection control is as follows: the outboard controller is used to control the outboard high-pressure control mechanism 30 to supply air to the outboard waste flushing and collection control mechanism 50, so that the pressure value in the channel of the outboard waste flushing and collection control mechanism 50 is consistent with the pressure value in the high-pressure cabin 100, and then controls the outboard waste flushing and collection control mechanism 50 to flush and collect the waste generated by 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 toward 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 is started. 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 collection bucket 503 through the dirt connecting pipe 502. When the timing reaches the set flushing time, the seventh electric-controlled valve 504 and the eighth electric-controlled 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.

[0030] The offboard controller is used to control the pressure relief electronically controlled valve to open after the set waste removal time has expired, allowing the high-pressure gas in the waste collection bucket 503 to be discharged through the exhaust pipe until the pressure value detected by the first pressure sensor 505 reaches normal pressure. At this time, the pressure relief electronically controlled valve is controlled to close, and the staff can remove 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 one. The bottom of the waste connecting pipe 502 is inserted into the waste collection bucket 503 and sealed at the insertion position. The right end of the second ventilation pipe 34 is inserted into the waste collection bucket 503 and sealed at the insertion position.

[0031] The off-cabin feeding control mechanism 60 includes an off-cabin feeding box 61, in which a second pressure sensor 62 is provided, and a first gravity sensor is fixed to the bottom of the off-cabin feeding box 61. The bottom of the off-cabin feeding box 61 is connected to the upper end of the feeding pipe 63, and the lower end of the feeding pipe 63 passes through the high-pressure cabin 100 and is inserted into the animal carrying cage 11. A ninth electric-controlled valve 64 is provided on the feeding pipe 63 and outside the high-pressure cabin 100. A feeding bowl 13 is docked directly below the feeding pipe 63, and the feeding bowl 13 is fixed on the inner wall of the animal carrying cage 11. The top of the off-cabin feeding box 61 is connected to the high-pressure gas tank 31 through the third ventilation pipe 36.

[0032] The feeding control principle is as follows: the offboard controller controls the offboard high-pressure control mechanism 30 to supply air to the offboard feeding control mechanism 60, ensuring that the pressure within the offboard feeding control mechanism 60 is consistent with the pressure within the high-pressure chamber 100. The offboard controller then controls the offboard feeding control mechanism 60 to provide food to the small animals. Specifically, when the set feeding time is reached, the offboard controller controls the fifth electrically controlled valve 37 to open, allowing high-pressure gas from the high-pressure gas tank 31 to enter the offboard feeding tank 60 through the third vent pipe 36 to pressurize the offboard feeding tank 60. When the pressure detected by the second pressure sensor 62 matches the pressure detected by the inboard pressure sensor 20, the fifth electrically controlled valve 37 is closed. Simultaneously, the ninth electrically controlled valve 64 is opened and a timer is set. Food from the offboard feeding tank 61 flows through the feeding pipe 63 into the feeding bowl 13 for the small animals to eat. When the timer reaches the set feeding time, the ninth electrically controlled valve 64 is closed. The outboard controller is further configured to send a message reminding the user to replenish food when the gravity detected by the first gravity sensor is lower than a first set weight value.

[0033] The extravehicular water supply control mechanism 70 includes an extravehicular water supply tank 71, a third pressure sensor 72 is provided in the extravehicular water supply tank 71, a second gravity sensor is fixed to the bottom of the extravehicular water supply tank 71, the bottom of the extravehicular water supply tank 71 is connected to the upper end of the water supply pipe 73, the lower end of the water supply pipe 73 passes through the high-pressure cabin 100 and is inserted into the animal carrying cage 11, a tenth electric-controlled valve 74 is provided on the water supply pipe 73 and located outside the high-pressure cabin 100, a water supply basin 14 is docked directly below the water supply pipe 73, the water supply basin 14 is fixed on the inner wall of the animal carrying cage 11, and the top of the extravehicular water supply tank 71 is connected to the high-pressure gas tank 31 through the fourth ventilation pipe 38.

[0034] The water supply control principle is as follows: the offboard controller controls the offboard high-pressure control mechanism 30 to supply air to the offboard water supply control mechanism 70, ensuring that the pressure within the offboard water supply control mechanism 70 is consistent with the pressure within the high-pressure chamber 100. The offboard controller then controls the offboard water supply control mechanism 70 to provide water to the small animals. Specifically, when the set water supply time is reached, the offboard controller controls the sixth electrically controlled valve 39 to open, allowing high-pressure gas from the high-pressure gas tank 31 to enter the offboard water supply tank 71 through the fourth vent pipe 38 to pressurize the offboard water supply tank 71. When the pressure detected by the third pressure sensor 72 matches the pressure detected by the inboard pressure sensor 20, the sixth electrically controlled valve 39 is closed. Simultaneously, the tenth electrically controlled valve 74 is opened and a timer is set. Water from the offboard water supply tank 71 flows through the water supply pipe 73 into the water supply basin 14 for the small animals to drink. When the timer reaches the set water supply time, the tenth electrically controlled valve 74 is closed. The outboard controller is further configured to send a message reminding the user to replenish water when the gravity detected by the second gravity sensor is lower than a second set weight value.
