Description

Technical Field

[0001] The present invention relates to the technical field of culture chambers, and particularly to a high-pressure small animal automatic culture chamber system. Background Art

[0002] The existing culture chambers for animal experiments under high pressure have the following defects: 1. Experimental small animals are placed in the culture chamber through an animal carrier box. The excrement produced by the experimental small animals will remain at the bottom of the animal carrier box and cannot be removed, which causes the deterioration of the environment in the culture chamber and even leads to the infection of small animals. If the experimental period is long, it may even lead to the failure of the experiment, etc. 2. There is no cleaning device in the chamber and it cannot be effectively cleaned, so the normal environment in the culture chamber cannot be guaranteed. 3. Generally, a certain amount of feed and water are pre-placed in the culture chamber for the small animals in the chamber to eat casually. This results in the feed and water being consumed quickly and it is impossible to replenish the feed and water in time, so it cannot be used for long-term animal experiments under high pressure. 4. Generally, a certain amount of carbon dioxide absorbent is directly spread flat in the culture chamber. In this way, the amount of the carbon dioxide absorbent is limited and it cannot be replaced in time when it is saturated with absorption, so it cannot be used for long-term animal experiments under high pressure. Summary of the Invention

[0003] In view of the problems and deficiencies existing in the prior art, the present invention provides a high-pressure small animal automatic culture chamber system.

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

[0005] The present invention provides a high-pressure small animal automatic culture chamber system, which is characterized in that it includes a chamber support, on which a chamber body is fixed. A first pressure sensor is arranged inside the chamber body. A through hole is opened at the bottom inside the chamber body, and an animal carrier box for carrying small animals is placed directly above the through hole. The bottom grille of the animal carrier box is fixed in the through hole. A dirt funnel is fixed on the outer side of the bottom of the chamber body. The top length of the dirt funnel is equal to the length of the bottom grille. A liquid level sensor is arranged inside the dirt funnel. The bottom sewage outlet of the dirt funnel is fixedly communicated with a transfer pipe, and a first electromagnetic valve is arranged on the transfer pipe. The bottom of the transfer pipe is fixedly communicated with a transfer barrel. The bottom sewage outlet of the transfer barrel is fixedly communicated with a collection pipe, and a second electromagnetic valve is arranged on the collection pipe. A collection barrel is arranged directly below the bottom sewage outlet of the collection pipe. The transfer barrel is connected and communicated with a high-pressure gas source through a first air inlet pipe, and a third electromagnetic valve is arranged on the first air inlet pipe. An exhaust pipe is externally connected to the transfer barrel, and a pressure relief valve is arranged on the exhaust pipe. A second pressure sensor is arranged inside the transfer barrel. A flushing water channel is opened along the circumferential direction inside the wall of the dirt funnel, and a plurality of flushing holes are opened along the circumferential direction on the inner wall of the dirt funnel. Each flushing hole is communicated with the flushing water channel. The flushing water channel is connected and communicated with one end of a flushing water pipe, and the other end of the flushing water pipe is inserted into a high-pressure water tank. A high-pressure water pump and a fourth electromagnetic valve are arranged on the flushing water pipe. The first pressure sensor, the liquid level sensor, the first electromagnetic valve, the second electromagnetic valve, the third electromagnetic valve, the pressure relief valve, the second pressure sensor, the high-pressure water pump and the fourth electromagnetic valve are all electrically connected to a control host.

[0006] The control host is used to control the third electromagnetic valve to open when the dirt liquid level detected by the liquid level sensor reaches the set liquid level value, so that the high-pressure gas in the high-pressure gas source enters the transfer barrel through the first air inlet pipe to pressurize the transfer barrel until the pressure value detected by the second pressure sensor is the same as the pressure value detected by the first pressure sensor. At this time, the third electromagnetic valve is controlled to close, and at the same time, the first electromagnetic valve and the fourth electromagnetic valve are controlled to open and the high-pressure water pump is started. The dirt in the dirt funnel flows into the transfer barrel through the transfer pipe. At the same time, the high-pressure water pump pumps the high-pressure water in the high-pressure water tank through the flushing water pipe and the flushing water channel and then pumps it out from the flushing holes to flush the dirt funnel. When the flushing time reaches the set flushing time, the first electromagnetic valve and the fourth electromagnetic valve are closed and the high-pressure water pump is paused.

[0007] The control host is also used to control the pressure relief valve to open after the current time reaches the set dirt collection time, so that the high-pressure gas in the transfer barrel is discharged through the exhaust pipe until the pressure value detected by the second pressure sensor is normal pressure, and then the second electromagnetic valve is controlled to open, and the dirt in the transfer barrel flows into the collection barrel through the collection pipe.

[0008] Moreover, a feed supply box is provided outside the cabin body. A third pressure sensor is arranged inside the feed supply box. The bottom of the feed supply box is fixedly communicated with a feed supply pipe. The bottom of the feed supply pipe is inserted into the animal carrying box. A fifth electromagnetic valve is arranged on the feed supply pipe. The top of the feed supply box is fixedly communicated with a second air inlet pipe. The other end of the second air inlet pipe is connected and communicated with a high-pressure air source. A sixth electromagnetic valve is arranged on the second air inlet pipe. A feed basin is fixed on the inner wall of the animal carrying box. The feed basin is located directly below the feed supply pipe. The third pressure sensor, the fifth electromagnetic valve and the sixth electromagnetic valve are all electrically connected to the control host.

[0009] When the current time reaches the set feeding time, the control host is used to control the sixth electromagnetic valve to open, so that the high-pressure air in the high-pressure air source enters the feed supply box through the second air inlet pipe to pressurize the feed supply box until the pressure value detected by the third pressure sensor is the same as the pressure value detected by the first pressure sensor. At this time, the control host controls the sixth electromagnetic valve to close, and at the same time controls the fifth electromagnetic valve to open and start timing. The feed in the feed supply box flows into the feed basin through the feed supply pipe for small animals to eat. When the timing time reaches the set feeding time, the control host controls the fifth electromagnetic valve to close.

[0010] A water supply box is also provided outside the cabin body. A fourth pressure sensor is arranged inside the water supply box. The bottom of the water supply box is fixedly communicated with a water supply pipe. The bottom of the water supply pipe is inserted into the animal carrying box. A seventh electromagnetic valve is arranged on the water supply pipe. The top of the water supply box is fixedly communicated with a third air inlet pipe. The other end of the third air inlet pipe is connected and communicated with a high-pressure air source. An eighth electromagnetic valve is arranged on the third air inlet pipe. A water basin is fixed on the inner wall of the animal carrying box. The water basin is located directly below the water supply pipe. The fourth pressure sensor, the seventh electromagnetic valve and the eighth electromagnetic valve are all electrically connected to the control host.

[0011] When the current time reaches the set water supply time, the control host is used to control the eighth electromagnetic valve to open, so that the high-pressure air in the high-pressure air source enters the water supply box through the third air inlet pipe to pressurize the water supply box until the pressure value detected by the fourth pressure sensor is the same as the pressure value detected by the first pressure sensor. At this time, the control host controls the eighth electromagnetic valve to close, and at the same time controls the seventh electromagnetic valve to open and start timing. The water in the water supply box flows into the water basin through the water supply pipe for small animals to drink. When the timing time reaches the set water adding time, the control host controls the seventh electromagnetic valve to close.

[0012] An agent tank is also provided outside the cabin. The agent tank is divided into a lower tank cavity and an upper tank cavity by a horizontal plate with a porous structure. An oxygen-producing agent is placed in the lower tank cavity, and a carbon dioxide absorbent is placed in the upper tank cavity. A temperature sensor is fixed to the top inner wall of the upper tank cavity. The cabin is fixedly communicated with an air outlet pipe, and the other end of the air outlet pipe is connected and communicated with the lower tank cavity. A tenth electromagnetic valve located outside the cabin is provided on the air outlet pipe. The cabin is fixedly communicated with a return air pipe, and the other end of the return air pipe is connected and communicated with the upper tank cavity. An eleventh electromagnetic valve located outside the cabin is provided on the return air pipe.

[0013] The control host is used to determine whether the temperature value detected by the temperature sensor reaches the set temperature value. When it is yes, it reminds to replace the oxygen-producing agent and the carbon dioxide absorbent in the agent tank, and controls the tenth electromagnetic valve and the eleventh electromagnetic valve to close. When the oxygen-producing agent and the carbon dioxide absorbent in the agent tank are replaced, it controls the tenth electromagnetic valve and the eleventh electromagnetic valve to open. The air in the cabin flows into the lower tank cavity through the air outlet pipe. Carbon dioxide in the air reacts with the oxygen-producing agent to generate oxygen, and the unreacted carbon dioxide is absorbed by the carbon dioxide absorbent in the upper tank cavity. The generated oxygen and the absorbed air flow into the cabin through the return air pipe.

[0014] The positive and progressive effects of the present invention are as follows:

[0015] In the present invention, the dirt produced by small animals is directly carried in the dirt funnel outside the cabin. After reaching a certain amount, it is transferred into the transfer barrel for storage and the dirt funnel is rinsed. Every day, the dirt in the transfer barrel is regularly put into the collection barrel and taken away by the staff. The present invention can greatly reduce the deterioration of the environment in the culture cabin, ensure the normal environment in the culture cabin, reduce the possibility of small animal infection, the test time is independently controllable, and it can be used for animal experiments under long-term high pressure.

[0016] In the present invention, the feeding structure and the water feeding structure are arranged outside the cabin, which is convenient for the staff to add feed and water, and can regularly provide feed and water for the small animals in the cabin, and can be used for animal experiments under long-term high pressure.

[0017] In the present invention, the carbon dioxide oxygen production and absorption structure is arranged outside the cabin, which is convenient for the staff to add the oxygen-producing agent and the carbon dioxide absorbent. The oxygen-producing agent and the carbon dioxide absorbent can be replaced in time after being saturated, and it can be used for animal experiments under long-term high pressure.

[0020] As Figure 1 shown, this embodiment provides a high-pressure small animal automatic culture chamber system, which includes a chamber support 1. A chamber 2 is fixed on the chamber support 1. A first pressure sensor 3 is arranged inside the chamber 2. A through hole is opened at the bottom of the chamber 3. An animal carrier box 4 for carrying small animals is placed directly above the through hole. The bottom grid 41 of the animal carrier box 4 is fixed in the through hole.

[0021] Dirt flushing and collection structure: A dirt funnel 5 is fixed on the outer side of the bottom of the chamber 2. The top length of the dirt funnel 5 is equal to the length of the bottom grid 41. A liquid level sensor 6 is arranged inside the dirt funnel 5. The bottom sewage outlet of the dirt funnel 5 is fixedly connected to a transfer pipe 7. A first solenoid valve 8 is arranged on the transfer pipe 7. The bottom of the transfer pipe 7 is fixedly connected to a transfer barrel 9. The bottom sewage outlet of the transfer barrel 9 is fixedly connected to a collection pipe 10. A second solenoid valve 11 is arranged on the collection pipe 10. A collection barrel 12 is arranged directly below the bottom sewage outlet of the collection pipe 10, and the bottom sewage outlet of the collection pipe 10 is placed in the upper part of the inside of the collection barrel 12. The transfer barrel 9 is connected and communicated with a high-pressure gas source 14 through a first intake pipe 13. A third solenoid valve 15 is arranged on the first intake pipe 13. The transfer barrel 9 is externally connected with an exhaust pipe 16. A pressure relief valve 17 is arranged on the exhaust pipe 16. A second pressure sensor 18 is arranged inside the transfer barrel 9. A flushing water channel is opened along the circumferential direction in the wall of the dirt funnel 5. A plurality of flushing holes 51 are opened along the circumferential direction on the inner wall of the dirt funnel 5. Each flushing hole 51 is communicated with the flushing water channel. The flushing water channel is connected and communicated with one end of a flushing water pipe 19. The other end of the flushing water pipe 19 is inserted into a high-pressure water tank 20. A high-pressure water pump 21 and a fourth solenoid valve 22 are arranged on the flushing water pipe 19. The first pressure sensor 3, the liquid level sensor 6, the first solenoid valve 8, the second solenoid valve 11, the third solenoid valve 15, the pressure relief valve 17, the second pressure sensor 18, the high-pressure water pump 21, and the fourth solenoid valve 22 are all electrically connected to a control host.

[0022] Control process for the dirt flushing and collection structure: The control host is used to control the opening of the third solenoid valve 15 when the dirt level detected by the liquid level sensor 6 reaches the set level value, so that the high-pressure gas in the high-pressure gas source 14 enters the transfer barrel 9 through the first intake pipe 13, thereby pressurizing the transfer barrel 9 until the pressure value detected by the second pressure sensor 18 is the same as the pressure value detected by the first pressure sensor 3, where the pressure value detected by the first pressure sensor 3 is the set high-pressure value. At this time, the third solenoid valve 15 is controlled to close, and at the same time, the first solenoid valve 8 and the fourth solenoid valve 22 are controlled to open, and the high-pressure water pump 21 is started. The dirt in the dirt funnel 5 flows into the transfer barrel 9 through the transfer pipe 7. At the same time, the high-pressure water pump 21 pumps the high-pressure water in the high-pressure water tank 20 through the flushing water pipe 19 and the flushing channel and then pumps it out from the flushing hole 51 at high pressure, thereby flushing the dirt funnel 5. When the flushing time reaches the set flushing time, the first solenoid valve 8 and the fourth solenoid valve 22 are closed, and the high-pressure water pump 21 is paused.

[0023] The control host is also used to control the opening of the pressure relief valve 17 after the current time reaches the set dirt collection time (such as collecting dirt at 6 pm every day), so that the high-pressure gas in the transfer barrel 9 is discharged through the exhaust pipe 16 until the pressure value detected by the second pressure sensor 18 is normal pressure, and then the second solenoid valve 11 is controlled to open, and the dirt in the transfer barrel 9 flows into the collection barrel 12 through the collection pipe 10.

[0024] In this solution, the dirt funnel 5 is placed outside the cabin body 2, and the dirt funnel 5 and the cabin body 2 are connected through the bottom grille 41, so that the pressure in the dirt funnel 5 is the same as the pressure in the cabin body 2. When it is necessary to transfer the dirt in the dirt funnel 5 to the transfer barrel 9, the pressure in the transfer barrel 9 needs to be the same as the pressure in the dirt funnel 5. The high-pressure gas in the high-pressure gas source 14 is used to pressurize the transfer barrel 9. After pressurization, the first solenoid valve 8 is opened, so that the dirt in the dirt funnel 5 flows into the transfer barrel 9. Since there is dirt residue on the inner wall of the dirt funnel 5, it is necessary to flush the dirt funnel 5. The high-pressure water in the high-pressure water tank 20 is used to flush the dirt funnel 5, thereby ensuring the environment in the cabin.

[0025] Feeding structure: A feed supply box 23 is provided outside the cabin body 2. A third pressure sensor 24 is provided inside the feed supply box 23. The bottom of the feed supply box 23 is fixedly communicated with a feed supply pipe 25. The bottom of the feed supply pipe 25 penetrates through the cabin body 2 and is inserted into the animal carrying box 4. A fifth solenoid valve 26 is provided on the feed supply pipe 25. The fifth solenoid valve 26 is placed outside the cabin body 2. The top of the feed supply box 23 is fixedly communicated with a second air inlet pipe 27. The other end of the second air inlet pipe 27 is connected and communicated with the high-pressure air source 14. A sixth solenoid valve 28 is provided on the second air inlet pipe 27. A feed basin 29 is fixed on the inner wall of the animal carrying box 4. The feed basin 29 is located directly below the feed supply pipe 25. The third pressure sensor 24, the fifth solenoid valve 26 and the sixth solenoid valve 28 are all electrically connected to the control host.

[0026] Control process for the feeding structure: The control host is used to control the sixth solenoid valve 28 to open when the current time reaches the set feeding time, so that the high-pressure air in the high-pressure air source enters the feed supply box 23 through the second air inlet pipe 27, thereby pressurizing the feed supply box 23 until the pressure value detected by the third pressure sensor 24 is the same as the pressure value detected by the first pressure sensor 3, where the pressure value detected by the first pressure sensor 3 is the set high-pressure value. At this time, the sixth solenoid valve 28 is controlled to close, and at the same time, the fifth solenoid valve 26 is controlled to open and start timing. The feed in the feed supply box 23 flows into the feed basin 29 through the feed supply pipe 25 for the small animals in the animal carrying box 4 to eat. When the timing time reaches the set feeding time, the fifth solenoid valve 26 is controlled to close.

The bottom of the water supply box 30 is fixedly communicated with a water supply pipe 32.

A water basin 36 is fixed on the inner wall of the animal carrying box 4. The water basin 36 is located directly below the water supply pipe 32. The fourth pressure sensor 31, the seventh solenoid valve 33 and the eighth solenoid valve 35 are all electrically connected to the control host.

[0028] Control process for the water injection structure: The control host is used to control the eighth solenoid valve 35 to open when the current time reaches the set water injection time, so that the high-pressure gas in the high-pressure gas source 14 enters the water supply tank 30 through the third air inlet pipe 34, thereby pressurizing the water supply tank 30 until the pressure value detected by the fourth pressure sensor 31 is the same as the pressure value detected by the first pressure sensor 3, where the pressure value detected by the first pressure sensor 3 is the set high-pressure value. At this time, the eighth solenoid valve 35 is controlled to close, and at the same time, the seventh solenoid valve 33 is controlled to open and start timing. The water in the water supply tank 30 flows into the water basin 36 through the water supply pipe 32 for the small animals in the animal carrying box 4 to drink. When the timing time reaches the set water addition time, the seventh solenoid valve 33 is controlled to close.

[0029] The cabin body 2 is fixedly communicated with a fourth air inlet pipe 36. The other end of the fourth air inlet pipe 36 is connected and communicated with the high-pressure gas source 14. A ninth solenoid valve 37 is arranged on the fourth air inlet pipe 36.

[0030] The control host is used to determine whether the pressure value detected by the first pressure sensor 3 reaches the set high-pressure value. When it is not, the ninth solenoid valve 37 is controlled to open, so that the high-pressure gas in the high-pressure gas source 14 enters the cabin body 2 through the fourth air inlet pipe 36, thereby pressurizing the cabin body 2 until the pressure value detected by the first pressure sensor 3 reaches the set high-pressure value. At this time, the ninth solenoid valve 37 is controlled to close.

[0031] Carbon dioxide oxygen generation and absorption structure: An agent tank 38 is also arranged outside the cabin body 2. The agent tank 38 is divided into a lower tank cavity 40 and an upper tank cavity 41 by a porous horizontal plate 39. An oxygen generating agent is placed in the lower tank cavity 40, and a carbon dioxide absorbent is placed in the upper tank cavity 41. A temperature sensor 42 is fixedly installed at the top of the inner wall of the upper tank cavity 41. The cabin body 2 is fixedly communicated with an air outlet pipe 43. The other end of the air outlet pipe 43 is connected and communicated with the lower tank cavity 40. A tenth solenoid valve 44 arranged outside the cabin is arranged on the air outlet pipe 43. The cabin body 2 is fixedly communicated with a return air pipe 45. The other end of the return air pipe 45 is connected and communicated with the upper tank cavity 41. An eleventh solenoid valve 46 arranged outside the cabin is arranged on the return air pipe 45.

[0032] Control process for carbon dioxide oxygen generation and absorption structure: The control host is used to determine whether the temperature value detected by the temperature sensor 42 reaches the set temperature value. When it is yes, it indicates that the carbon dioxide absorbent at the top inside the upper tank cavity 41 has started to absorb carbon dioxide, and the carbon dioxide absorbent is about to be used up. It reminds to replace the oxygen generator and carbon dioxide absorbent in the agent tank 38, and controls the tenth solenoid valve 44 and the eleventh solenoid valve 46 to close. When the oxygen generator and carbon dioxide absorbent in the agent tank 38 are replaced, it controls the tenth solenoid valve 44 and the eleventh solenoid valve 46 to open. The air in the cabin 2 flows into the lower tank cavity 40 through the air outlet pipe 43. The carbon dioxide in the air reacts with the oxygen generator to generate oxygen. The unreacted carbon dioxide is absorbed by the carbon dioxide absorbent in the upper tank cavity 41. The generated oxygen and the air after being absorbed by the carbon dioxide absorbent flow into the cabin 2 through the return air pipe 45.

[0033] In this solution, the air in the cabin 2 first flows into the lower tank cavity 40 through the air outlet pipe 43. The carbon dioxide in the air first reacts with the oxygen generator in the lower tank cavity 40 to generate oxygen. The generated oxygen flows through the upper tank cavity 41 and the return air pipe 45 into the cabin 2. The carbon dioxide that does not react with the oxygen generator is absorbed by the carbon dioxide absorbent in the upper tank cavity 41. The air after the carbon dioxide is absorbed flows into the cabin 2 through the return air pipe 45.

The protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.

5. The high-pressure small animal automatic culture chamber system according to claim 1, characterized in that, An agent tank is further provided outside the cabin body. The agent tank is divided into a lower tank cavity and an upper tank cavity by a horizontal plate with a porous structure. An oxygen-producing agent is placed in the lower tank cavity, and a carbon dioxide absorbent is placed in the upper tank cavity. A temperature sensor is fixed to the top of the inner wall of the upper tank cavity. The cabin body is fixedly communicated with an air outlet pipe, and the other end of the air outlet pipe is connected and communicated with the lower tank cavity. A tenth electromagnetic valve placed outside the cabin is provided on the air outlet pipe. The cabin body is fixedly communicated with a return air pipe, and the other end of the return air pipe is connected and communicated with the upper tank cavity. An eleventh electromagnetic valve placed outside the cabin is provided on the return air pipe; The control host is used to determine whether the temperature value detected by the temperature sensor reaches the set temperature value. When it is, it reminds to replace the oxygen-producing agent and the carbon dioxide absorbent in the agent tank, and controls the tenth electromagnetic valve and the eleventh electromagnetic valve to close. When the oxygen-producing agent and the carbon dioxide absorbent in the agent tank are replaced, it controls the tenth electromagnetic valve and the eleventh electromagnetic valve to open. The air in the cabin flows into the lower tank cavity through the air outlet pipe. Carbon dioxide in the air reacts with the oxygen-producing agent to generate oxygen, and the unreacted carbon dioxide is absorbed by the carbon dioxide absorbent in the upper tank cavity. The generated oxygen and the absorbed air flow into the cabin through the return air pipe.

6. The high-pressure small animal automatic culture chamber system according to claim 1, characterized in that, The bottom sewage outlet of the collection pipe is placed in the upper part inside the collection bucket.
