Abstract

The invention discloses a double-chamber linked plateau low-pressure simulation cabin frame, and belongs to the technical field of plateau environment simulation equipment. Comprising a cabin body, two simulation cabins are symmetrically arranged in the cabin body, extraction openings are symmetrically formed in the upper surface of the cabin body, extraction cavities are symmetrically and fixedly connected to the upper surface of the cabin body, the upper surfaces of the extraction cavities are jointly and fixedly communicated with a cavity, the upper surface of the cavity is fixedly communicated with an extraction pump, and the upper surface of the cavity is fixedly communicated with an air outlet. In the technical field of plateau environment simulation, a traditional low-pressure simulation cabin generally adopts a single-cavity structure or a double-cavity independent control mode, and obvious technical limitation exists. On one hand, a single-chamber simulation cabin cannot meet the requirement that multiple groups of experiments are carried out simultaneously, and the experiment efficiency is low; and on the other hand, although part of double-chamber equipment has a linkage function, a flexible chamber opening and closing control mechanism is lacked, and when only a single group of experiments need to be carried out, the double chambers still need to be started for synchronous air exhaust.

Description

Technical Field

[0001] This invention relates to plateau environment simulation equipment technology, and more particularly to a plateau low-pressure simulation chamber frame with dual-chamber linkage. Background Technology

[0002] In the field of high-altitude environment simulation technology, traditional low-pressure simulation chambers typically employ a single-chamber structure or a dual-chamber independent control mode, which presents significant technical limitations. On the one hand, single-chamber simulation chambers cannot meet the needs of conducting multiple experiments simultaneously, resulting in low experimental efficiency. On the other hand, while some dual-chamber devices have linkage functions, they lack flexible chamber opening and closing control mechanisms. When only a single experiment is required, it is still necessary to activate both chambers for synchronous air extraction, leading to energy waste and increased equipment wear and tear.

[0003] Traditional designs lack intelligent sensors to detect the sealing status of the cabin doors. If researchers start the equipment without fully closing the doors, it may cause deviations in the accuracy of the air pressure simulation and even pose safety hazards. Furthermore, existing technologies struggle to precisely adjust air pressure values, failing to meet the diverse experimental needs of simulating different altitudes. Their complex structures also lead to cumbersome operation, limiting the flexibility and practicality of high-altitude low-pressure simulation experiments. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to achieve synchronous and precise adjustment of the air pressure in the dual chambers. It can precisely control the air pressure value in the simulation chamber according to the adjustment of the working power or pumping time of the air pump, thereby matching the low-pressure environment corresponding to different altitudes and solving the problems of low experimental efficiency of traditional single-chamber simulation chambers and insufficient linkage accuracy of dual-chamber equipment. Another purpose of this invention is to achieve independent opening and closing control of a single simulation chamber.

[0005] Technical solution: A high-altitude low-pressure simulation chamber frame with dual chamber linkage, including a chamber body, with two simulation chambers symmetrically opened inside the chamber body. The upper surface of the chamber body is symmetrically provided with air extraction ports. The upper surface of the chamber body is symmetrically fixedly connected with air extraction chambers. The upper surfaces of the air extraction chambers are fixedly connected to a cavity. The upper surface of the cavity is fixedly connected to an air extraction pump. The output end of the air extraction pump is fixedly connected to the cavity.

[0006] Furthermore, the outer wall of the suction chamber is symmetrically provided with sliding grooves, and a blocking plate is slidably connected inside each sliding groove. A horizontal plate is fixedly connected to the right end of each blocking plate. A spring groove is fixedly connected to each outer wall of the suction chamber, and a spring post is slidably connected inside each spring groove. A sliding plate is fixedly connected to the left end of each spring post inside the spring groove. A return spring is wound around the outer wall of each spring post, and the spring post is fixedly connected to the outer wall of the adjacent horizontal plate.

[0007] Furthermore, a telescopic cavity is fixedly connected to the outer wall of the left horizontal plate, and a sliding rod is slidably connected inside the telescopic cavity. The right end of the sliding rod is fixedly connected to the outer wall of the right horizontal plate, and the left end of the sliding rod is slidably connected to a limit block inside the telescopic cavity.

[0008] Furthermore, a support rod is symmetrically fixedly connected to the left side of the horizontal plate on the left, and a baffle is fixedly connected between the two support rods. A toothed plate is fixedly connected to the outer side wall of the front support rod. A motor is fixedly connected to the front surface of the air extraction chamber on the left, and a gear is fixedly connected to the output end of the motor. The gear meshes with the toothed plate.

[0009] Furthermore, each of the simulation cabins has a placement opening at the front, and the front surface of the placement opening is connected to a sealed front door via a hinge.

[0010] Furthermore, a sensing slot is provided on the front right side of the simulation cabin, and a sensor switch is fixedly connected inside the sensing slot. An electric telescopic rod is fixedly connected to the upper surface of the front telescopic cavity. The bottom end of the electric telescopic rod extends into the interior of the telescopic cavity and contacts the limiting block. The sensor switch and the electric telescopic rod are connected by a wire signal.

[0011] Furthermore, a switch slot is provided on the right side of the outer wall of the simulation cabin, and motor switches are symmetrically fixedly connected inside the switch slot.

[0012] Beneficial Effects: In the field of high-altitude environment simulation technology, traditional low-pressure simulation chambers typically employ a single-chamber structure or a dual-chamber independent control mode, which presents significant technical limitations. On the one hand, single-chamber simulation chambers cannot meet the needs of conducting multiple experiments simultaneously, resulting in low experimental efficiency. On the other hand, while some dual-chamber devices possess linkage functions, they lack flexible chamber opening and closing control mechanisms. When only a single experiment is required, simultaneous evacuation of both chambers is still necessary, leading to energy waste and increased equipment wear. Furthermore, traditional designs lack intelligent sensing of the chamber door's sealing status. If the experimenter starts the equipment without fully closing the door, it may cause deviations in the accuracy of the air pressure simulation and even pose safety hazards. Simultaneously, existing technologies struggle to precisely adjust air pressure values, failing to meet the diverse experimental needs of simulating different altitudes. Moreover, the complex structure leads to cumbersome operation, limiting the flexibility and practicality of high-altitude low-pressure simulation experiments.

[0013] This dual-chamber linkage high-altitude low-pressure simulation chamber achieves synchronous and precise pressure regulation of both chambers through an integrated design of the air pump, cavity, and extraction chamber. When the air pump is activated, air from both simulation chambers is simultaneously discharged into the cavity and then out through the extraction port and extraction chamber, causing the air pressure to decrease linearly with the extraction time or pump power, accurately matching the low-pressure environment of the target altitude. For example, by adjusting the air pump power, the chamber pressure can be reduced from standard atmospheric pressure to 40 kPa (equivalent to 5000 meters above sea level) within 30 minutes, with an error range controlled within ±1.5 kPa, meeting the high-precision requirements for high-altitude environment simulation in fields such as aviation and medicine. Furthermore, the dual-chamber linkage design allows for the simultaneous conduct of two sets of control experiments, such as simultaneously testing the performance changes of different materials under the same low-pressure environment. This doubles the experimental efficiency compared to single-chamber equipment and avoids data deviations caused by equipment differences in independent chambers, ensuring data comparability and reliability.

[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-7 As shown, a high-altitude low-pressure simulation chamber frame with dual-chamber linkage is provided, including a chamber 1. Two simulation chambers 2 are symmetrically opened inside the chamber 1. Air extraction ports 3 are symmetrically opened on the upper surface of the chamber 1. Air extraction chambers 4 are symmetrically fixedly connected to the upper surface of the chamber 1. The upper surface of the air extraction chambers 4 are all fixedly connected to a cavity 5. An air extraction pump 6 is fixedly connected to the upper surface of the cavity 5. The output end of the air extraction pump 6 is fixedly connected to the cavity 5.

[0025] When simulating a high-altitude, low-pressure environment, the air extraction pump 6 is activated. The pump 6 begins operation, its output end drawing air out of cavity 5, creating negative pressure within cavity 5. Since the extraction chamber 4 is fixedly connected to cavity 5, air in extraction chamber 4 is rapidly drawn into cavity 5 under the influence of the pressure difference. Meanwhile, two symmetrically arranged simulation chambers 2 inside the chamber 1 are connected to extraction chamber 4 via extraction ports 3. Air in simulation chamber 2 is sequentially drawn through extraction ports 3 and extraction chamber 4 into cavity 5, and then discharged by the air extraction pump 6. During this continuous extraction process, the air pressure in both simulation chambers 2 decreases synchronously, achieving dual-chamber linkage and jointly simulating the low-pressure environment corresponding to the altitude. By adjusting the operating power or extraction time of the air extraction pump 6, the air pressure value in simulation chamber 2 can be precisely controlled to meet different high-altitude, low-pressure simulation experimental requirements.

[0026] In this embodiment, the outer wall of the suction chamber 4 is symmetrically provided with sliding grooves 7. A blocking plate 8 is slidably connected inside each sliding groove 7. A horizontal plate 9 is fixedly connected to the right end of each blocking plate 8. Spring grooves 10 are fixedly connected to the outer wall of the suction chamber 4. Spring posts 11 are slidably connected inside each spring groove 10. A sliding plate 12 is fixedly connected to the left end of each spring post 11 inside the spring groove 10. A return spring 13 is wound around the outer wall of each spring post 11. The spring post 11 is fixedly connected to the outer wall of the adjacent horizontal plate 9. A telescopic cavity 14 is fixedly connected to the outer wall of the left horizontal plate 9. A sliding rod 15 is slidably connected inside the telescopic cavity 14. The right end of the sliding rod 15 is fixedly connected to the outer wall of the right horizontal plate 9. A limit block 16 is slidably connected to the left end of the left horizontal plate 9 inside the telescopic cavity 14. A support rod 17 is connected to the front support rod 17, and a baffle 18 is fixedly connected between the two support rods 17. A toothed plate 19 is fixedly connected to the outer wall of the front support rod 17. A motor 20 is fixedly connected to the front surface of the left air extraction chamber 4. A gear 21 is fixedly connected to the output end of the motor 20. The gear 21 meshes with the toothed plate 19. A placement port 22 is opened in front of each simulation chamber 2. A sealed front door 23 is rotatably connected to the front surface of the placement port 22 through a hinge. A sensing groove 24 is opened on the right side of the front of the simulation chamber 2. A sensor switch 25 is fixedly connected inside the sensing groove 24. An electric telescopic rod 29 is fixedly connected to the upper surface of the front telescopic chamber 14. The bottom end of the electric telescopic rod 29 extends into the interior of the telescopic chamber 14 and contacts the limit block 16. The sensor switch 25 and the electric telescopic rod 29 are connected by a wire signal.

[0027] When preparing to conduct a simulation experiment, if the sealed front door 23 of the right simulation chamber 2 is closed, the closing of the sealed front door 23 will trigger the induction switch 25 in the induction slot 24. The induction switch 25 sends a signal to the electric telescopic rod 29 through the wire, and the electric telescopic rod 29 descends after receiving the signal. When the electric telescopic rod 29 abuts against the limiting block 16, the motor 20 is started. The motor 20 drives the gear 21 to rotate, and through meshing with the toothed plate 19, it drives the left horizontal plate 9 to move. The horizontal plate 9 pulls the spring 11 to compress the reset spring 13, and through the slide rod 15, it drives the right horizontal plate 9 to move synchronously, so that the two blocking plates 8 slide open, realizing the simultaneous opening of the two air extraction chambers 4. If the right sealing front door 23 is not closed and the induction switch 25 is not triggered, the electric telescopic rod 29 is in the retracted state, no longer abutting against the limiting block 16, and no longer restricting the slide rod 15 to move to the right. The slide rod 15 will retract inside. At this time, the motor 20 is started, and the left horizontal plate 9 can only drive the left blocking plate 8 to slide, opening the left air extraction chamber 4, while the right air extraction chamber 4 remains closed, thereby realizing the air pressure simulation effect of starting a single simulation chamber 2, realizing the effect of opening the simulation experiment as needed.

[0028] In this embodiment, a switch slot 26 is provided on the right side of the outer wall of the simulation chamber 2, and a motor switch 27 is symmetrically fixedly connected inside the switch slot 26;

[0029] Pressing the two motor switches 27 starts the motor 20, which drives the gear 21 to rotate. By meshing with the toothed plate 19, the gear 21 moves the horizontal plates 9 on both sides synchronously, causing the two blocking plates 8 to slide open. This allows the two air extraction chambers 4 to open simultaneously, and works with the air extraction pump 6 to complete the high-altitude low-pressure simulation of the dual chamber linkage.

[0030] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
