[0002] The sealed cabin of pharmaceutical equipment refers to a special equipment structure used in the pharmaceutical process. Its main function is to provide a completely closed environment to ensure that the drugs are not contaminated or deteriorated during the manufacturing, storage and transportation process. The sealed cabin usually has high strength, pressure resistance and excellent sealing performance to prevent air, moisture, light and other external factors from adversely affecting the drugs.

[0003] According to the search of Chinese patent CN110702322A, it involves a comprehensive leak detection sealed cabin, including a sealed cabin body and a sealed cover. The sealed cabin body is a double-layer cylindrical structure, the bottom of the sealed cabin body is sealed, and the upper end of the sealed cabin body is connected to the sealing cover through a clamping mechanism; a storage rack is set at the bottom center of the inner cavity of the sealed cabin body, and a through-hole is set on the side wall of the sealed cabin body, and a cover plate is installed at the port of the through-hole; the sealed cabin body of the present invention adopts a double-layer sealing structure to ensure the sealing performance of the equipment itself, and the helium leaked from the inspected part can be obtained through the through-hole to realize the testing function. The through-hole is used to connect the through-hole electrical plug to ensure the normal operation of the built-in circulation system. A rack is set in the sealed cabin body to fix the inspected product stably in the middle, with the same spacing on all sides, which protects the product and makes the test more accurate; According to the search of Chinese patent CN210108650U, it involves a biopharmaceutical equipment sealed cabin body leak detector, including a high-pressure gas storage tank, an exhaust pipe, a bronchial tube, and a connecting joint. The outlet of the high-pressure gas storage pipe is provided with a ball valve, the bronchial tube is provided with a one-way valve, the exhaust pipe is provided with a control box, the control box is provided with an air pressure detection sensor, the exhaust pipe is provided with an electronic pressure reducing valve for controlling the outlet pressure of the exhaust pipe, the control box is provided with a controller, and the control box is provided with a communication module. The utility model uses a high-pressure gas tank to increase the pressure of the biopharmaceutical equipment sealed cabin to be detected, uses a remotely controllable electronic pressure reducing valve to control the air supply and pressure adjustment of the high-pressure gas tank to the outside world, and uses an air pressure detection sensor to perform pressure detection on the pressurized biopharmaceutical equipment sealed cabin, thereby detecting the sealing effect of the biopharmaceutical equipment sealed cabin, without the need to supply air to the biopharmaceutical equipment sealed cabin from the outside world, the detection is more accurate, and there is no need to equip the biopharmaceutical equipment sealed cabin with a configuration specifically used for detection, and the applicability is better; According to Chinese patent CN105172996B, a method for using an airtight cabin with a hole in an inverted ship is disclosed, and the steps are as follows: 1. The bottom surface of the sealed cabin body is sealed and fixed to the bottom of the inverted ship by a sealing assembly; 2. The cutting personnel opens the outer sealing door, enters the transition cabin, closes the outer sealing door, opens the inner sealing door, enters the working cabin, closes the inner sealing door, and pressurizes the working cabin through an airtight nozzle. After pressurization, the working cabin is leak-checked and leak-proof, and then a hole is cut in the bottom of the inverted ship by a cutting device; 3. After the hole is opened, the cutting personnel enters the transition cabin, closes the inner sealing door, and walks out of the sealed cabin body. A diver carrying an oxygen cylinder enters the transition cabin, closes the outer sealing door, enters the working cabin, closes the inner sealing door, and enters the inside of the inverted ship from the opening to perform rescue work. The rescue personnel carry out the hole opening and rescue work in the closed environment provided by the airtight cabin, which is safe to operate, efficient, and saves rescue time; The above patent has the same inconvenience as the existing pharmaceutical equipment when in use: although the equipment can accurately detect the leakage position of the sealed cabin when in use, after the leakage is found, when the sealed cabin is reopened for maintenance or adjustment, the unlocking process takes a long time due to the complex locking structure of the sealed cabin. This situation not only affects the operating efficiency of the pharmaceutical equipment, but may also cause unnecessary delays to the pharmaceutical process.

[0015] The present invention also provides a leak detection method for a sealed cabin of pharmaceutical equipment, which further comprises the following steps: S1: When the sealed cabin needs to be closed and sealed, we can operate the first electric push rod to extend its extended end, and then push the sealing cover to fit tightly against the sealed cabin to ensure a good sealing effect. Once the sealing cover completely covers the sealed cabin, the second electric push rod can be further driven to extend its extended end, push the rotating disk to rotate, and drive the moving part to move toward the sealed cabin. During this process, the moving part will simultaneously drive the clamping part to clamp and fix the sealing cover, thereby not only enhancing the sealing performance of the sealed cabin, but also achieving a stable locking of the sealed cabin. The operation process is more efficient and accurate, which helps to improve the overall sealing effect and safety of the sealed cabin. S2: When there is a leak at the connection between the sealed cabin and the sealing cover, the sensor can quickly capture this abnormality and accurately locate the specific location of the leak. Once the sensor detects a leak, it will immediately transmit this information to the controller. After receiving the signal, the controller will respond quickly, control the LED light to flash, and activate the alarm sound of the buzzer. The dual visual and auditory prompts are designed to quickly attract and arouse the attention of the staff so that they can take necessary measures to repair the leak in time; S3: Every time the sealing cover is opened, the sealing cover will come into contact with the airbag pump and produce extrusion, and the contact extrusion activates the airbag pump. After being subjected to pressure, the gas in the airbag pump will quickly enter the storage tank from the air outlet end, which not only releases the gas in the airbag, but also uses the impact force of the gas to drive the push rod forward, thereby driving the sliding plate to slide. As the sliding plate moves, the disinfectant stored in the storage tank is sprayed to the connection between the sealed cabin and the sealing cover, ensuring that the connection can be disinfected in a timely and effective manner every time the sealing cover is opened, thereby effectively reducing the breeding and spread of bacteria or viruses. When the sealing cover is fully opened and no longer in contact with the airbag pump, the airbag pump gradually restores its original deformation. At this time, the air inlet end begins to inhale air, and the air outlet end stops exhausting air, so that the airbag pump returns to its initial state, ready for the next extrusion and activation; S4: When the second electric push rod is driven to lock the rotating disk, the rotating disk will rotate clockwise. This rotation action will drive the push plate, which in turn causes the push plate to push the rotating plate to slide smoothly along the slide rod. As the rotating plate moves, the sponge it carries will gradually contact and squeeze the outer wall of the observation window, thereby cleaning the observation window. When the rotating disk continues to push the rotating plate and the sponge contacts the support rod, the torsion spring will be deformed by the external force. This deformation allows the push plate to slide smoothly along the surface of the rotating plate, ensuring that the rotation process will not be affected. When the push plate is no longer in contact with the sliding plate, the torsion spring will immediately restore its original deformation and prepare for the next squeezing and deformation. During the unlocking operation, when the second electric push rod is driven to rotate the rotating disk counterclockwise, the whole cleaning process will occur again. The rotating disk drives the push plate, and the push plate drives the rotating plate to slide along the sliding rod again, so that the sponge wiper contacts and cleans the outer wall of the observation window again. In this way, each rotation of the rotating disk can realize automatic cleaning of the observation window, ensuring that the observation window always remains clear and transparent, making it convenient for the staff to observe the situation of the sealed cabin at any time.

[0016] Technical effects and advantages of the present invention: The present invention not only improves the sealing performance of the sealed cabin, but also adds a locking mechanism, thereby achieving the dual functions of sealing and locking, not only ensuring the high sealing performance of the sealed cabin in the closed state and effectively preventing the leakage of gas or liquid, but also significantly improving the locking speed and efficiency, making the opening and closing process of the sealed cabin more convenient and rapid. When the sealing cover is closed in place, the locking mechanism will automatically start to lock the sealing cover on the sealed cabin, which is not only easy to operate, but also has a stable locking effect, and can effectively prevent the sealing cover from being opened inadvertently. At the same time, the unlocking process is also efficient, and the locked state can be easily released with a simple operation, making the sealing cover more convenient and rapid. The airtightness of the airtight cabin is greatly improved, which not only ensures the high sealing of the airtight cabin when the lid is tightly closed, but also effectively prevents the risk of pressure accumulation or leakage caused by excessive gas. When there is a leak at the connection between the airtight cabin and the sealing cover, the sensor can quickly capture the abnormality and accurately locate the specific location of the leak. Once the sensor detects a leak, it will This information is immediately transmitted to the controller. After receiving the signal, the controller will respond quickly, control the LED light to flash, and activate the alarm sound of the buzzer. The dual prompting methods of vision and hearing are designed to quickly attract and arouse the attention of the staff so that they can take necessary measures to repair the leakage problem in time; whenever the sealing cover and the sealing cabin are opened or closed, the linkage mechanism will be triggered. This mechanism is closely connected with the airbag pump to ensure that the airbag pump can be driven to work during each operation. The airbag pump is filled with an appropriate amount of disinfectant. Once activated, it can quickly spray the disinfectant. To the connection between the sealing cover and the sealing cabin; each time the sealing cabin is opened, it not only enhances its sealing, but also drives the sponge to automatically clean the observation window, effectively solving the problem that humans may forget to clean, and ensuring that the cleanliness of the observation window is maintained in time. As the sealing cabin is opened, the sponge will slide back and forth on the observation window, effectively removing stains and dust attached to it. This automatic cleaning design not only improves the timeliness of cleaning, but also ensures the uniformity and thoroughness of cleaning. Compared with traditional manual cleaning, it avoids the problem of untimely cleaning due to human negligence or forgetfulness, and also reduces the labor intensity of staff.

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 creative work are within the scope of protection of the present invention.

[0019] The present invention provides Figure 1 - Fig. 9The leak detection equipment for the sealed cabin of pharmaceutical equipment shown in the figure includes a box body 1, a sealed cabin 2 and an observation window 3. The box body 1, as the cornerstone of the entire equipment, firmly supports the sealed cabin 2, ensuring the stability of the equipment during operation.

[0020] The surface of the box body 1 is provided with a sealing component 4 for increasing the sealing performance of the sealed cabin 2. The sealing performance of the sealed cabin 2 is improved, and a locking mechanism is added at the same time, thereby realizing the dual functions of sealing and locking, which not only ensures the high sealing performance of the sealed cabin 2 in the closed state and effectively prevents the leakage of gas or liquid, but also significantly improves the locking speed and efficiency, making the opening and closing process of the sealed cabin 2 more convenient and rapid; The sealing assembly 4 includes a first electric push rod 401, which is fixedly arranged on the surface of the box body 1. A sealing cover 402 is slidably arranged on the surface of the sealed cabin 2. An exhaust valve 403 is connected to the inner wall of the sealed cabin 2. A one-way valve is arranged at one end of the exhaust valve 403. When the sealing cover 402 and the sealed cabin 2 are tightly closed, the gas in the sealed cabin 2 is squeezed by the sealing cover 402, and part of the gas will be smoothly guided to the exhaust valve 403. The presence of the one-way valve ensures the unidirectional exhaust of the gas and prevents the external gas from flowing back into the sealed cabin 2.

[0021] The surface of the box body 1 is fixedly provided with a support frame 404, the first electric push rod 401 is fixedly provided on the surface of the support frame 404, the extended end of the electric push rod 505 is fixed to the sealing cover 402, the outer side wall of the sealed cabin 2 has a plurality of support members 405 fixedly provided at equal distances, the surface of the support member 405 is provided with a sliding groove 406, the inner wall of the sliding groove 406 is slidably connected with a moving member 407, and a clamping member 408 is fixedly provided on the side of the moving member 407 close to the sealed cabin 2, and the sealed cabin 2 is rotatably provided with a rotating disk 409 on its outer wall, and a plurality of arc grooves 410 are equidistantly provided on the surface of the rotating disk 409; a limiting rod 411 is rotatably provided on the surface of the moving member 407, and the outer wall of the limiting rod 411 is rotatably connected to the inner wall of the arc groove 410; a second electric push rod 505 is fixedly provided on the surface of the box body 1; a rotating shaft 413 is rotatably provided on a side of the rotating disk 409 close to the second electric push rod 505, and the rotating shaft 413 is rotatably connected to the protruding end of the second electric push rod 505.

[0022] There are multiple sensors 414 fixedly arranged at equal intervals on the rotating disk 409. It should be noted that the model of the position sensor 414 is: Shengkaian NE-101 plate-type infrared gas sensor 414.

[0023] The sensor 414 faces the sealed cabin 2, an LED lamp 415 is fixedly provided on the surface of the support frame 404, a buzzer is provided on the LED lamp 415, a controller is fixedly provided on the surface of the support frame 404, an input end of the controller is electrically connected to an output end of the sensor 414, and the input ends of the LED lamp 415 and the buzzer are electrically connected to the controller; It should be noted that the controller is an existing conventional technical means and is not shown in the figure and will not be described here.

[0024] Working principle: When the sealed cabin 2 needs to be closed, the extended end of the first electric push rod 401 is extended by driving it, and the extended end of the first electric push rod 401 is retracted to extend with the sealing cover 402. When the sealing cover 402 contacts the sealed cabin 2, the extended end of the second electric push rod 505 is driven to extend, and the extended end of the second electric push rod 505 drives the rotating shaft 413 to rotate, and the rotating shaft 413 rotates to drive the rotating disk 409 to rotate. When the rotating disk 409 rotates, the arc groove 410 abuts against the limit rod 411, and the limit rod 411 is moved to drive the moving part 407 along the sliding groove 4 06 slides toward one side of the sealed cabin 2, and the moving member 407 slides with the clamping member 408. When the moving member 407 moves so that the clamping member 408 contacts the outer wall of the sealing cover 402, the extended end of the first electric push rod 401 is continuously driven to extend. At this time, the rotating disk 409 continues to rotate so that the arc groove 410 continues to move the limit rod 411 to slide with the moving member 407 in the direction of the sealing cover 402. When the clamping member 408 completely clamps the sealing cover 402, the second electric push rod 505 is closed, thereby completing the sealing of the sealed cabin 2. When a leak occurs at the connection between the sealed cabin 2 and the sealing cover 402, the sensor 414 can quickly capture this abnormal situation and accurately locate the specific location of the leak. Once the sensor 414 detects a leak, it will immediately transmit this information to the controller. After receiving the signal, the controller will respond quickly, controlling the LED light 415 to flash and activating the alarm sound of the buzzer. The dual visual and auditory prompts are intended to quickly attract and cause the attention of the staff so that they can take necessary measures in time to repair the leak.

[0025] The inner wall of the support frame 404 is provided with a disinfection component 5 for disinfecting the sealed cabin 2 after it is opened. It mainly utilizes the force of the sealing cover 402 when it is opened and then closed to disinfect the connection between the sealed cabin 2 and the sealing cover 402. The disinfection component 5 utilizes the force generated when the sealing cover 402 is opened and then closed, and effectively disinfects the connection between the sealed cabin 2 and the sealing cover 402.

[0026] The disinfection component 5 includes an airbag inflator 501, which is fixedly arranged on the inner wall of the support frame 404, and one side of the airbag inflator 501 is connected to an air inlet end 502, and the side of the airbag inflator 501 away from the air inlet end 502 is connected to an air outlet end 503, and both the air inlet end 502 and the air outlet end 503 are provided with a one-way valve, and a storage tank 504 is fixedly arranged on the inner wall of the support frame 404 close to the airbag inflator 501, and a push rod 505 is arranged on the inner wall of the storage tank 504, and a sliding plate 506 is slidably arranged on the inner wall of the storage tank 504, and the sliding plate 506 is fixed to the push rod 505, and the air outlet end 503 passes through the storage tank 504 and is connected to the push rod 505, and the side of the storage tank 504 away from the air outlet end 503 is connected to a liquid outlet pipe 507, and the liquid outlet pipe 507 faces the sealed cabin 2.

[0027] Working principle: When the sealed cabin 2 needs to be closed, the extended end of the first electric push rod 401 is extended by driving it, and the extended end of the first electric push rod 401 is retracted to extend with the sealing cover 402. When the sealing cover 402 extends to contact the airbag pump 501, the gas in the airbag pump 501 will quickly enter the storage tank 504 from the gas outlet end 503, which not only releases the gas in the airbag, but also uses the impact force of the gas to drive the push rod 505 forward, thereby driving the sliding plate 506 to slide. As the sliding plate 506 moves, the storage tank 504 is The disinfectant in the storage tank is sprayed to the connection between the sealed cabin 2 and the sealing cover 402, ensuring that the connection can be promptly and effectively disinfected each time the sealing cover 402 is opened, thereby effectively reducing the breeding and spread of bacteria or viruses. When the sealing cover 402 is fully opened and no longer in contact with the airbag pump 501, the airbag pump 501 gradually restores its original deformation. At this time, the air inlet end 502 starts to inhale air, while the air outlet end 503 stops exhausting air, so that the airbag pump 501 returns to its initial state, ready for the next squeezing and activation. The surface of the box body 1 is provided with a cleaning component 6 for cleaning the observation window 3, which mainly utilizes the second electric push rod 505 to drag the rotating disk 409 to rotate the sealing cover 402 and the sealing cabin 2 to increase the sealing force to clean the outer wall of the observation window 3. Each time the sealing cabin 2 is opened, it not only enhances its sealing performance, but also drives the sponge 603 to automatically clean the observation window 3, effectively solving the problem that manual cleaning may be forgotten, and ensuring that the cleanliness of the observation window 3 is maintained in time. With the opening action of the sealing cabin 2, the sponge 603 will slide back and forth on the observation window 3 to effectively remove stains and dust attached thereto. This automatic cleaning design not only improves the timeliness of cleaning, but also ensures the uniformity and thoroughness of cleaning. Compared with traditional manual cleaning, it avoids the problem of untimely cleaning due to human negligence or forgetfulness, and also reduces the labor intensity of the staff.

[0028] A support rod 601 is fixedly provided on the surface of the box body 1, a sliding rod 602 is fixedly provided on the inner wall of the support rod 601, a sponge 603 is slidably connected to the surface of the sliding rod 602, the sponge 603 is in squeeze contact with the outer wall of the observation window 3, a rotating plate 604 is rotatably provided on the top of the sponge 603 through a torsion spring, a push plate 605 is fixed to the outer wall of the rotating disk 409, and the push plate 605 is in contact with the rotating plate 604.

[0029] Working principle: when the second electric push rod 505 is driven to lock the rotating disk 409, the rotating disk 409 will rotate clockwise, and this rotation action will drive the push plate 605, and then the push plate 605 will drive the rotating plate 604 to slide smoothly along the slide rod 602. As the rotating plate 604 moves, the sponge 603 it carries will gradually contact and squeeze the outer wall of the observation window 3, thereby cleaning the observation window 3. When the rotating disk 409 continues to push the rotating plate 604 and the sponge 603 contacts the support rod 601, the torsion spring will be deformed by the external force, and this deformation enables the push plate 605 to slide smoothly along the surface of the rotating plate 604, ensuring the rotation. The movement process will not be hindered. Once the pushing plate 605 is no longer in contact with the sliding plate 506, the torsion spring will immediately restore its original deformation and prepare for the next squeezing and deformation. During the unlocking operation, when the second electric push rod 505 is driven to make the rotating disk 409 rotate counterclockwise, the whole cleaning process will occur again. The rotating disk 409 drives the pushing plate 605, and the pushing plate 605 again drives the rotating plate 604 to slide along the sliding rod 602, so that the sponge 603 contacts and cleans the outer wall of the observation window 3 again. In this way, each rotation of the rotating disk 409 can realize automatic cleaning of the observation window 3, ensuring that the observation window 3 always remains clear and transparent, making it convenient for the staff to observe the situation of the sealed cabin 2 at any time.

[0030] The present invention also provides a method for leak detection of a sealed cabin 2 of pharmaceutical equipment, which further comprises the following steps: S1: When the sealed cabin 2 needs to be closed and sealed, we can operate the first electric push rod 401 to extend its protruding end, and then push the sealing cover 402 to fit tightly against the sealed cabin 2 to ensure a good sealing effect. Once the sealing cover 402 completely covers the sealed cabin 2, the second electric push rod 505 can be further driven to extend its protruding end, push the rotating disk 409 to rotate, and drive the moving part 407 to move toward the sealed cabin 2. During this process, the moving part 407 will synchronously drive the clamping part 408 to clamp and fix the sealing cover 402, thereby not only enhancing the sealing performance of the sealed cabin 2, but also achieving a stable locking of the sealed cabin 2. The operation process is more efficient and accurate, which helps to improve the overall sealing effect and safety of the sealed cabin 2. S2: When there is a leak at the connection between the sealed cabin 2 and the sealing cover 402, the sensor 414 can quickly capture this abnormal situation and accurately locate the specific location of the leak. Once the sensor 414 detects a leak, it will immediately transmit this information to the controller. After receiving the signal, the controller will quickly respond by controlling the LED light 415 to flash and activating the alarm sound of the buzzer. The dual visual and auditory prompts are intended to quickly attract and arouse the attention of the staff so that they can take necessary measures to repair the leak in time; S3: Every time the sealing cover 402 is opened, the sealing cover 402 will come into contact with the airbag pump 501 and produce extrusion, and the contact extrusion activates the airbag pump 501. After being subjected to pressure, the gas in the airbag pump 501 will quickly enter the storage tank 504 from the air outlet end 503, which not only releases the gas in the airbag, but also uses the impact force of the gas to drive the push rod 505 forward, thereby driving the sliding plate 506 to slide. As the sliding plate 506 moves, the disinfectant stored in the storage tank The air is sprayed to the connection between the sealed cabin 2 and the sealing cover 402, ensuring that the connection can be promptly and effectively disinfected each time the sealing cover 402 is opened, thereby effectively reducing the growth and spread of bacteria or viruses. When the sealing cover 402 is fully opened and no longer in contact with the airbag pump 501, the airbag pump 501 gradually restores its original shape. At this time, the air inlet end 502 starts to inhale air, while the air outlet end 503 stops exhausting air, so that the airbag pump 501 returns to its initial state, ready for the next squeezing and activation. S4: When the second electric push rod 505 is driven to lock the rotating disk 409, the rotating disk 409 will rotate clockwise. This rotation action will drive the push plate 605, and then the push plate 605 will drive the rotating plate 604 to slide smoothly along the slide bar 602. As the rotating plate 604 moves, the sponge 603 it carries will gradually contact and squeeze the outer wall of the observation window 3, thereby cleaning the observation window 3. When the rotating disk 409 continues to push the rotating plate 604 and the sponge 603 contacts the support rod 601, the torsion spring will be deformed by the external force. This deformation enables the push plate 605 to slide smoothly along the surface of the rotating plate 604, ensuring the rotation. The process will not be hindered. Once the pushing plate 605 is no longer in contact with the sliding plate 506, the torsion spring will immediately restore its original deformation and prepare for the next squeezing and deformation. During the unlocking operation, when the second electric push rod 505 is driven to make the rotating disk 409 rotate counterclockwise, the entire cleaning process will occur again. The rotating disk 409 drives the pushing plate 605, and the pushing plate 605 again drives the rotating plate 604 to slide along the sliding rod 602, so that the sponge 603 contacts and cleans the outer wall of the observation window 3 again. In this way, each rotation of the rotating disk 409 can realize automatic cleaning of the observation window 3, ensuring that the observation window 3 always remains clear and transparent, making it convenient for the staff to observe the situation of the sealed cabin 2 at any time.

A leak detection method for a sealed cabin of pharmaceutical equipment, characterized in that: The invention comprises a leak detection device for a sealed cabin of pharmaceutical equipment according to any one of claims 1 to 9, further comprising the following steps: S1: When the sealed cabin (2) needs to be closed and sealed, we can operate the first electric push rod (401) to extend its protruding end, thereby pushing the sealing cover (402) to fit tightly against the sealed cabin (2) to ensure a good sealing effect. Once the sealing cover (402) completely covers the sealed cabin (2), the second electric push rod (505) can be further driven to extend its protruding end, thereby pushing the rotating disk (409) to rotate, thereby driving the moving part (407) to move toward the sealed cabin (2). During this process, the moving part (407) will simultaneously drive the clamping part (408) to clamp and fix the sealing cover (402), thereby not only enhancing the sealing performance of the sealed cabin (2), but also achieving a stable locking of the sealed cabin (2). The operation process is more efficient and accurate, which helps to improve the overall sealing effect and safety of the sealed cabin (2); S2: When a gas leak occurs at the connection between the sealed cabin (2) and the sealed cover (402), the sensor (414) can quickly capture this abnormal situation and accurately locate the specific location of the gas leak. Once the sensor (414) detects the gas leak, it will immediately transmit this information to the controller. After receiving the signal, the controller will quickly respond by controlling the LED light (415) to flash and activating the alarm sound of the buzzer. The dual visual and auditory prompts are intended to quickly attract and arouse the attention of the staff so that they can take necessary measures to repair the gas leak in time. S3: Each time the sealing cover (402) is opened, the sealing cover (402) will come into contact with the airbag pump (501) and generate compression, and the contact compression activates the airbag pump (501). After being subjected to pressure, the gas in the airbag pump (501) will quickly enter the storage tank (504) from the gas outlet end (503), which not only releases the gas in the airbag, but also utilizes the impact force of the gas to drive the push rod (505) forward, thereby driving the sliding plate (506) to slide. As the sliding plate (506) moves, the sterilized substances stored in the storage tank are released. The liquid is sprayed onto the connection between the sealing cabin (2) and the sealing cover (402), ensuring that each time the sealing cover (402) is opened, the connection can be promptly and effectively disinfected, thereby effectively reducing the growth and spread of bacteria or viruses. When the sealing cover (402) is fully opened and no longer in contact with the airbag pump (501), the airbag pump (501) gradually restores its original deformation. At this time, the air inlet end (502) starts to inhale air, while the air outlet end (503) stops exhausting air, so that the airbag pump (501) returns to its initial state and is ready for the next squeezing and activation. S4: When the second electric push rod (505) is driven to lock the rotating disk (409), the rotating disk (409) will rotate clockwise. This rotation action will drive the push plate (605), and then the push plate (605) will push the rotating plate (604) to slide smoothly along the slide rod (602). As the rotating plate (604) moves, the sponge (603) it carries will gradually contact and squeeze the outer wall of the observation window (3), thereby achieving cleaning of the observation window (3). When the rotating disk (409) continues to push the rotating plate (604) and the sponge (603) contacts the support rod (601), the torsion spring will be deformed by the external force. This deformation enables the push plate (605) to slide smoothly along the surface of the rotating plate (604), ensuring The rotation process will not be hindered. Once the push plate (605) is no longer in contact with the sliding plate (506), the torsion spring will immediately restore its original deformation and prepare for the next squeezing and deformation. During the unlocking operation, when the second electric push rod (505) is driven to rotate the rotating disk (409) counterclockwise, the entire cleaning process will occur again. The rotating disk (409) drives the push plate (605), and the push plate (605) again drives the rotating plate (604) to slide along the sliding rod (602), so that the sponge (603) contacts and cleans the outer wall of the observation window (3) again. In this way, each rotation of the rotating disk (409) can realize automatic cleaning of the observation window (3), ensuring that the observation window (3) always remains clear and transparent, so that the staff can observe the situation of the sealed cabin (2) at any time.
