[0014] The present invention also discloses a method for adjusting a pressure regulating device for a pressurized cabin, comprising the following steps:

[0015] Step 1: Monitor and display the air pressure in the pressurized cabin body in real time according to the pressure gauge to ensure that the air pressure value is within a safe range. When adjusting the air pressure in the pressurized cabin body, first start the driving mechanism to run the motor, so that the output shaft of the motor drives the rotating rod to rotate, so that the rotating rod drives the first sprocket to rotate synchronously, and the first sprocket drives the first chain to rotate, thereby driving the threaded barrel to rotate. When the threaded barrel rotates, the threaded rod slides into the threaded barrel, and at the same time, the threaded rod drives the sealing plate to move, so that the sealing plate drives the guide block to slide along the guide rod, so that the sealing plate slides away from the partition, thereby exposing the connection port on the partition;

[0016] The threaded cylinder drives the differential wheel to rotate synchronously while rotating, so that the differential wheel drives the second chain to rotate, thereby driving the connecting rod to rotate synchronously, so that the connecting rod drives the bevel gear to rotate, and the bevel gear drives the rectangular plate to rotate, thereby exposing the rectangular opening on the connecting plate. At this time, the pressurized cabin body and the connecting pipe are in a connected state;

[0017] Step 2: According to the value on the pressure gauge, when the air pressure in the pressurized cabin body is low, the external gas is discharged into the pressurized cabin body through the connecting pipe. When the air pressure in the pressurized cabin body is high, the regulating valve is operated so that the connecting pipe on the right side of the pressurized cabin body is exhausted. At the same time, the regulating valve accurately controls the discharge of gas to adjust the air pressure inside the pressurized cabin body.

[0018] Step three: After adjusting the air pressure in the pressurized cabin body, close the regulating valve, and then move the sealing plate so that the sealing plate slides and contacts the partition. At the same time, the sealing ring on the sealing plate is in close contact with the sealing ring on the partition, thereby sealing the connecting port on the partition. At the same time, the rectangular plate rotates and contacts the rectangular port in close contact, thereby cutting off the gas exchange channel between the pressurized cabin body and the outside world, and sealing the pressurized cabin body. The operation efficiency is high.

[0019] Compared with the related art, the pressure regulating device and regulating method of the pressurized cabin provided by the present invention have the following beneficial effects:

[0020] Compared with the prior art, the pressurized cabin air pressure regulating device provided in this scheme ensures that the air pressure inside the pressurized cabin body is stable and will not leak through precise air pressure regulation and the setting of multiple sealing structures, thereby effectively protecting personnel and equipment from adverse external factors. At the same time, through the setting of the driving mechanism, the movement of the sealing plate and the rectangular plate is faster and more accurate, which greatly simplifies the fixing process of the multiple sealing structures and improves work efficiency.

[0021] In summary, the pressurized cabin air pressure regulating device of the present invention can close multiple sealing structures simultaneously and relatively quickly, thereby improving the convenience and efficiency of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides a pressure regulating device for a pressurized cabin, such as Figure 1-10 As shown, the pressure regulating device of the pressurized cabin includes: a pressurized cabin body 1 and a group of connecting pipes 2 installed on both sides of the pressurized cabin body 1; a group of pressure gauges 3 arranged on the pressurized cabin body 1 for monitoring the air pressure in the pressurized cabin body 1; a group of regulating valves 4 respectively installed on a group of the connecting pipes 2; a partition 5 fixedly installed in the pressurized cabin body 1, and a connecting port is opened on the partition 5; a sealing plate 6 for sealing the connecting port is arranged on one side of the partition 5; an auxiliary sealing mechanism arranged in the connecting pipe 2 for sealing the connecting pipe 2; and a driving mechanism arranged on the pressurized cabin body 1 for driving the sealing plate 6 to move.

[0036] In this embodiment, the pressure gauge 3 monitors and displays the air pressure in the pressurized cabin body 1 in real time to ensure that the air pressure value is within a safe range. When adjusting the air pressure in the pressurized cabin body 1, the driving mechanism is first started to drive the sealing plate 6 to slide, so that the sealing plate 6 slides away from the connecting port. At the same time, the auxiliary sealing mechanism is opened to rotate the rectangular plate 9, so that the rectangular port is exposed. After that, the regulating valve 4 can be opened to adjust the air pressure in the pressurized cabin body 1.

[0037] According to the value on the pressure gauge 3, when the air pressure in the pressurized cabin body 1 is low, the external air compressor discharges the gas into the pressurized cabin body 1 through the connecting pipe 2 to increase the air pressure in the pressurized cabin body 1. When the air pressure in the pressurized cabin body 1 is high, the regulating valve 4 is controlled to allow the connecting pipe 2 located on the right side of the pressurized cabin body 1 to perform exhaust operation. At the same time, the air pressure in the pressurized cabin body 1 decreases. The regulating valve 4 accurately controls the discharge of gas to adjust the air pressure inside the pressurized cabin body 1. Through precise air pressure regulation and the setting of multiple sealing structures, the air pressure inside the pressurized cabin body 1 is ensured to be stable and leak-free, effectively protecting personnel and equipment from adverse external factors. At the same time, through the setting of the driving mechanism, the movement of the sealing plate 6 and the rectangular plate 9 is faster and more accurate, which greatly simplifies the fixing process of the multiple sealing structures and improves work efficiency.

[0038] In a further preferred embodiment of the present invention, the auxiliary sealing mechanism includes: a connecting plate 8 fixedly installed in the connecting tube 2, and a rectangular opening is opened on the connecting plate 8; a rectangular plate 9 rotatably installed in the rectangular opening, and the output rod of the rectangular plate 9 extends out of the connecting tube 2; a sealing strip 10 fixedly sleeved on the rectangular plate 9, and the sealing strip 10 is in rotational contact with the rectangular opening.

[0039] In this embodiment, after adjusting the air pressure in the pressurized cabin body 1, the rectangular plate 9 is rotated so that the rectangular plate 9 is rotated to contact the rectangular opening on the connecting plate 8, and at the same time, the sealing strip 10 on the rectangular plate 9 is in close contact with the rectangular opening, thereby sealing the connecting pipe 2. At the same time, the sealing plate 6 seals the connecting opening, thereby ensuring that the gas in the pressurized cabin body 1 will not leak, and the sealing effect is good. Through the close cooperation between the rectangular plate 9 and the sealing strip 10, even in a high-pressure environment, it can effectively prevent gas from leaking from the connecting pipe 2, further improving the sealing performance of the pressurized cabin body 1.

[0040] In a further preferred embodiment of the present invention, the driving mechanism includes: a support plate 11 fixedly mounted in the pressurized cabin body 1; a threaded barrel 12 rotatably mounted on the support plate 11, a threaded rod 13 being threadedly mounted in the threaded barrel 12, and one end of the threaded rod 13 being fixedly connected to the sealing plate 6; a mounting block 14 fixedly mounted on the top of the pressurized cabin body 1, a rotating rod 15 being rotatably mounted on the mounting block 14; a group of first sprockets 16 fixedly mounted on the rotating rod 15 and the threaded barrel 12 respectively; a connecting port opened on the top of the pressurized cabin body 1; a first chain 17 mounted on a group of the first sprockets 16, the first chain 17 passing through the connecting port; a motor 18 fixedly mounted on the top of the pressurized cabin body 1, and the output shaft of the motor 18 being fixedly connected to the rotating rod 15.

[0041] In this embodiment, when the air pressure in the pressurized cabin body 1 is adjusted, the motor 18 is first operated so that the output shaft of the motor 18 drives the rotating rod 15 to rotate, so that the rotating rod 15 drives the first sprocket 16 to rotate synchronously, and the first sprocket 16 drives the first chain 17 to rotate, thereby driving the threaded cylinder 12 to rotate. When the threaded cylinder 12 rotates, the threaded rod 13 slides into the threaded cylinder 12, and at the same time, the threaded rod 13 drives the sealing plate 6 to move, so that the sealing plate 6 drives the guide block 20 to slide along the guide rod 19, so that the sealing plate 6 slides away from the partition 5, thereby exposing the connecting port on the partition 5. After the pressurized cabin body 1 is connected with the connecting pipe 2, the air pressure in the pressurized cabin body 1 can be adjusted. Through the drive of the motor 18 and the sprocket chain transmission, the sealing plate 6 is remotely and accurately controlled without manual operation, thereby improving work efficiency and safety.

[0042] In a further preferred embodiment of the present invention, a guide rod 19 is fixedly mounted on one side of the partition plate 5 , a guide block 20 is slidably mounted on the guide rod 19 , and the top of the guide block 20 is fixedly connected to the bottom of the sealing plate 6 .

[0043] In this embodiment, when the driving mechanism drives the sealing plate 6 to move, the sealing plate 6 will drive the guide block 20 to slide along the guide rod 19. The synergistic effect of the guide rod 19 and the guide block 20 ensures the stability and accuracy of the sealing plate 6 during the movement. The combined use of the guide rod 19 and the guide block 20 effectively limits the movement trajectory of the sealing plate 6, avoids the problem of poor sealing due to movement deviation, and improves the accuracy and reliability of the seal. At the same time, the guide rod 19 provides stable support and guidance for the movement of the sealing plate 6, making the sealing plate 6 more stable during the movement.

[0044] In a further preferred embodiment of the present invention, a connecting box 21 is installed on the top of the connecting pipe 2, one side of the connecting box 21 is fixedly connected to the pressurized cabin body 1, and a connecting rod 22 is rotatably installed on one side of the partition 5, and one end of the connecting rod 22 extends into the connecting box 21.

[0045] In this embodiment, the connection rod 22 is protected by the connection box 21 to ensure that external objects or operators will not contact the components in the connection box 21, which is beneficial to improving the safety of the device.

[0046] In a further preferred embodiment of the present invention, the connecting rod 22 and the output rod of the rectangular plate 9 are fixedly sleeved with a bevel gear 23, a group of the bevel gears 23 are meshed with each other, the connecting rod 22 and the threaded cylinder 12 are fixedly sleeved with a differential wheel 24, a group of the differential wheels 24 are sleeved with a second chain 25, and the second chain 25 is meshed with a group of the differential wheels 24.

[0047] In this embodiment, the threaded barrel 12 drives the differential wheel 24 to rotate synchronously while rotating, so that the differential wheel 24 drives the second chain 25 to rotate, thereby driving the connecting rod 22 to rotate synchronously, so that the connecting rod 22 drives the bevel gear 23 to rotate, and the bevel gear 23 drives the rectangular plate 9 to rotate, thereby exposing the rectangular opening on the connecting plate 8. When the rectangular opening and the connecting opening are both exposed, the regulating valve 4 can be operated to adjust the air pressure in the pressurized cabin body 1. Through the meshing of the bevel gear 23 and the cooperation of the differential wheel 24 and the second chain 25, the synchronous rotation of the connecting rod 22, the rectangular plate 9 and the threaded barrel 12 is achieved, thereby improving the coordination and stability of the entire device.

[0048] In a further preferred embodiment of the present invention, a rectangular frame 26 is installed on the top of the pressurized cabin body 1 , a protective box 27 is provided on the rectangular frame 26 , and the protective box 27 is covered on the motor 18 and the rotating rod 15 .

[0049] In this embodiment, the design of the protective box 27 effectively prevents the motor 18 and the rotating rod 15 from being damaged or malfunctioning due to external factors (such as dust, moisture, foreign matter, etc.), thereby improving the safety of the entire device. By protecting the motor 18 and the rotating rod 15 from the influence of the external environment, the protective box 27 helps to reduce component damage caused by wear, corrosion, etc., thereby extending the service life of the equipment. Since the motor 18 and the rotating rod 15 are effectively protected, the repair and replacement work required due to failures is reduced, thereby reducing maintenance costs and workload.

[0050] In a further preferred embodiment of the present invention, a bracket 28 is fixedly installed on one side of the rectangular frame 26, a screw rod 29 is rotatably installed on the bracket 28, a rectangular tube 30 is threadedly sleeved on the screw rod 29, and the rectangular tube 30 is slidably connected to the rectangular frame 26 and the protective box 27.

[0051] In this embodiment, the position of the rectangular tube 30 is precisely adjusted by the combination of the screw rod 29 and the rectangular tube 30. This adjustment method is not only simple and convenient, but also easy to quickly load and unload the protective box 27, and the operation is relatively quick.

[0052] In a further preferred embodiment of the present invention, a liquid storage box 31 is fixedly installed on the top of the inner wall of the protective box 27, a dropper 32 is installed on one side of the liquid storage box 31, the mouth of the dropper 32 is located above the first chain 17 and the first sprocket 16, a valve is provided on the dropper 32, a liquid inlet is opened on the top of the protective box 27, the liquid inlet is communicated with the liquid storage box 31, and a sealing plug 33 is provided in the liquid inlet.

[0053] In this embodiment, when lubrication is required for the first chain 17 and the first sprocket 16, the sealing plug 33 of the liquid inlet is first opened, and an appropriate amount of lubricating liquid is added into the liquid storage box 31 through the liquid inlet. Then, the valve on the dropper 32 is adjusted as needed to control the dripping speed and frequency of the lubricating liquid. Under the action of gravity, the lubricating liquid accurately drips onto the contact surface of the first chain 17 and the first sprocket 16 through the dropper 32 to achieve automatic lubrication. By regularly providing lubrication to the first chain 17 and the first sprocket 16, the friction and wear between them can be significantly reduced, thereby extending the service life of the equipment.

[0054] The present invention also provides a method for adjusting a pressure regulating device for a pressurized cabin, comprising the following steps:

[0055] Step 1: Monitor and display the air pressure in the pressurized cabin body 1 in real time according to the pressure gauge 3 to ensure that the air pressure value is within a safe range. When adjusting the air pressure in the pressurized cabin body 1, first start the driving mechanism to operate the motor 18, so that the output shaft of the motor 18 drives the rotating rod 15 to rotate, so that the rotating rod 15 drives the first sprocket 16 to rotate synchronously, and the first sprocket 16 drives the first chain 17 to rotate, thereby driving the threaded barrel 12 to rotate. When the threaded barrel 12 rotates, the threaded rod 13 slides into the threaded barrel 12, and at the same time, the threaded rod 13 drives the sealing plate 6 to move, so that the sealing plate 6 drives the guide block 20 to slide along the guide rod 19, so that the sealing plate 6 slides away from the partition 5, thereby exposing the connection port on the partition 5;

[0056] The threaded cylinder 12 drives the differential wheel 24 to rotate synchronously while rotating, so that the differential wheel 24 drives the second chain 25 to rotate, thereby driving the connecting rod 22 to rotate synchronously, so that the connecting rod 22 drives the bevel gear 23 to rotate, and the bevel gear 23 drives the rectangular plate 9 to rotate, thereby exposing the rectangular opening on the connecting plate 8. At this time, the pressurized cabin body 1 and the connecting pipe 2 are in a connected state;

[0057] Step 2: According to the value on the pressure gauge 3, when the air pressure in the pressurized cabin body 1 is low, the external gas is discharged into the pressurized cabin body 1 through the connecting pipe 2; when the air pressure in the pressurized cabin body 1 is high, the regulating valve 4 is controlled so that the connecting pipe 2 located on the right side of the pressurized cabin body 1 performs exhaust operation, and the regulating valve 4 accurately controls the discharge of gas to adjust the air pressure inside the pressurized cabin body 1;

[0058] Step three: After adjusting the air pressure in the pressurized cabin body 1, close the regulating valve 4, and then move the sealing plate 6 so that the sealing plate 6 slides and contacts the partition 5. At the same time, the sealing ring 7 on the sealing plate 6 is in close contact with the sealing ring 7 on the partition 5, thereby sealing the connecting port on the partition 5. At the same time, the rectangular plate 9 rotates and contacts the rectangular port in close contact, thereby cutting off the gas exchange channel between the pressurized cabin body 1 and the outside world, and sealing the pressurized cabin body 1. The operation efficiency is relatively high.

[0059] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0061] In this embodiment, when the connecting rod 22 rotates, it drives the second sprocket 37 to rotate, so that the second sprocket 37 drives the third chain 38 to rotate, and the second sprocket 37 drives the cleaning brush 36 to rotate, so that the cleaning brush 36 rotates to clean the dust or impurities on the screen 34, thereby ensuring that the screen 34 will not be blocked, and at the same time, it can also ensure that the air discharged into the pressurized cabin body 1 is clean. By rotating the connecting rod 22, the cleaning brush 36 automatically rotates, so that the cleaning brush 36 can continuously and effectively scrape off the impurities on the screen 34, keeping the screen 34 unobstructed. At the same time, cleaning the screen 34 can prevent blockage and wear caused by the accumulation of impurities, thereby extending the service life of the screen 34.

[0063] In this embodiment, the dust cleaned by the cleaning brush 36 is discharged into the collecting chamber through the discharge port and the guide hopper 41, so that the collecting chamber collects the dust, which is convenient for subsequent centralized cleaning operations. Through the design of multiple screens 34 and corresponding collecting chambers, dust of different particle sizes can be collected.

When adjusting the air pressure in the pressurized cabin body (1), first start the driving mechanism to operate the motor (18), so that the output shaft of the motor (18) drives the rotating rod (15) to rotate, so that the rotating rod (15) drives the first sprocket (16) to rotate synchronously, so that the first sprocket (16) drives the first chain (17) to rotate, thereby driving the threaded barrel (12) to rotate. When the threaded barrel (12) rotates, the threaded rod (13) slides into the threaded barrel (12), and at the same time, the threaded rod (13) drives the sealing plate (6) to move, so that the sealing plate (6) drives the guide block (20) to slide along the guide rod (19), so that the sealing plate (6) slides away from the partition (5), thereby exposing the connection port on the partition (5); The threaded cylinder (12) drives the differential wheel (24) to rotate synchronously while rotating, so that the differential wheel (24) drives the second chain (25) to rotate, thereby driving the connecting rod (22) to rotate synchronously, so that the connecting rod (22) drives the bevel gear (23) to rotate, and the bevel gear (23) drives the rectangular plate (9) to rotate, thereby exposing the rectangular opening on the connecting plate (8). At this time, the pressurized cabin body (1) and the connecting pipe (2) are in a connected state; Step 2: According to the value on the pressure gauge (3), when the air pressure in the pressurized cabin body (1) is low, the external air is discharged into the pressurized cabin body (1) through the connecting pipe (2); when the air pressure in the pressurized cabin body (1) is high, the regulating valve (4) is operated so that the connecting pipe (2) located on the right side of the pressurized cabin body (1) performs an exhaust operation, and at the same time, the regulating valve (4) accurately controls the discharge of the gas to adjust the air pressure inside the pressurized cabin body (1); Step three: After adjusting the air pressure in the pressurized cabin body (1), close the regulating valve (4), and then move the sealing plate (6) so that the sealing plate (6) slides and contacts the partition (5), and at the same time, the sealing ring (7) on the sealing plate (6) is in close contact with the sealing ring (7) on the partition (5), thereby sealing the connecting port on the partition (5). At the same time, the rectangular plate (9) rotates and contacts the rectangular port closely, thereby cutting off the gas exchange channel between the pressurized cabin body (1) and the outside world, and sealing the pressurized cabin body (1), with high operating efficiency.
