Description

Technical Field

[0001] This invention relates to the field of space environment simulation test equipment, specifically to a space environment simulation test equipment. Background Technology

[0002] Space environment simulation test equipment is used to simulate low-pressure vacuum environments, solar radiation environments, and cold black environments in high altitudes and outer space. The equipment includes components such as a cabin heat sink, a hatch heat sink, and piping connecting the hatch heat sink to the heat exchange equipment for circulating cooling liquid.

[0003] Existing space environment simulation test equipment has the following shortcomings: When test specimens and / or test equipment need to be installed inside the cabin heat sink, the cabin door heat sink cannot be moved forward or backward, making it inconvenient to install test specimens and / or test equipment inside the cabin heat sink. The pipeline cannot simultaneously and accurately follow the hot sinking of the hatch in a synchronized manner, and cannot maintain the pipeline in the predetermined shape in real time. During the forward and backward movement of the hatch heat sink, it is impossible to ensure that the hatch heat sink and the heat exchange equipment remain in a constant state of communication. The communication needs to be disconnected, which cannot ensure that the test is not interrupted, cannot improve the continuity of the test process, and cannot significantly improve the test efficiency and shorten the test preparation cycle. During the forward and backward movement of the hot-sinking chamber, it is impossible to avoid the pipes being scattered, and it is impossible to prevent the pipes from getting tangled or rubbing, which could lead to wear or leakage. This cannot significantly improve the safety of the test, and it is necessary to manually arrange and fold the pipes, which cannot eliminate the possibility of human error damaging the pipes. During the forward and backward movement of the hatch hot sink, it is impossible to provide continuous and stable movement trajectory guidance for the pipeline, and it is impossible to avoid local stress concentration or irregular deformation of the pipeline due to free bending, thus failing to effectively reduce the risk of fatigue damage to the pipeline. During the forward and backward movement of the hatch hot sink, it is impossible to suppress the disorderly swinging and shaking of the pipeline, prevent the pipeline from colliding or getting stuck with other components, and significantly extend the service life of the pipeline.

[0016] Therefore, the present invention provides the following effects and / or advantages: 1) When the test specimen and / or test equipment need to be installed in the heat sink of the cabin, the heat sink of the cabin door can be moved back and forth, so as to facilitate the installation of the test specimen and / or test equipment in the heat sink of the cabin. The pipeline can simultaneously and accurately follow the hot sink of the hatch in a synchronous and stable manner, and can maintain the pipeline in a predetermined shape in real time. During the forward and backward movement of the hatch heat sink, it can ensure that the hatch heat sink and the heat exchange equipment remain connected without disconnection, ensuring that the test is not interrupted, improving the continuity of the test process, significantly improving test efficiency and shortening the test preparation cycle. During the forward and backward movement of the hatch hot sink, the pipes can be prevented from being scattered, and the pipes can be prevented from being tangled, rubbed, worn or leaking. This can greatly improve the safety of the test, eliminate the need for manual handling of folded pipes, and prevent damage to the pipes due to human error. During the forward and backward movement of the hatch hot sink, it can provide continuous and stable movement trajectory guidance for the pipeline, which can avoid local stress concentration or irregular deformation caused by free bending of the pipeline, and effectively reduce the risk of fatigue damage to the pipeline. During the forward and backward movement of the hatch hot sink, it can suppress disorderly swinging and shaking of the pipeline, prevent the pipeline from colliding or getting stuck with other components, and significantly extend the service life of the pipeline.

[0017] 2) During the movement of the hatch heat sink forward to a predetermined position or backward to the initial position driven by the shaft-shifting drive mechanism, the sliding table is continuously driven to move forward or backward, the first arc plate is continuously driven to adhere to the following drag chain, and both second arc plates are driven to rotate a predetermined angle towards the first arc plate and continuously adhere to the following drag chain; this actively and in real time guides the following drag chain to maintain a U-shaped bend during the movement of the hatch heat sink forward to the predetermined position or backward to the initial position, thereby ensuring that the inlet hose and return hose always maintain smooth bending and extension during the movement of the hatch heat sink forward to the predetermined position or backward to the initial position, improving the smoothness and safety of the inlet hose and return hose in delivering cooling liquid; this ensures that the inlet hose and return hose maintain a smooth bend and extension during the movement of the hatch heat sink forward to the predetermined position or backward to the initial position, improving the smoothness and safety of the cooling liquid delivery during the movement of the hatch heat sink; During the forward movement of the hot sinker to the predetermined position or the backward movement to the initial position, the system actively and in real-time suppresses lateral swaying and longitudinal shaking of the following cable chain. This provides a continuous and stable movement path for the inlet and return hoses during the forward movement of the hot sinker to the predetermined position or the backward movement to the initial position, and significantly improves the trajectory accuracy of the inlet and return hoses as they follow the hot sinker. Furthermore, it actively and in real-time ensures more even stress distribution at the bends of the following cable chain during the forward movement of the hot sinker to the predetermined position or the backward movement to the initial position, thereby preventing excessive wear or fatigue damage to the inlet and return hoses due to localized stress concentration, and further extending the service life of the following cable chain, inlet hoses, and return hoses. When the axial displacement drive mechanism moves the hatch hot sink forward to a predetermined position or backward to its initial position, the sliding platform is first driven to remain stationary. Then, the two second arc plates are driven to rotate a predetermined angle away from the first arc plate and continuously press against the following drag chain. Next, the first arc plate is driven to continuously press against the following drag chain. This proactively pre-expands and adjusts the attitude of the bending points of the following drag chain while the hatch hot sink is not moving, and actively eliminates creep deformation and misalignment caused by long-term static placement or temperature changes. This ensures that the following drag chain, inlet hose, and return hose can start moving from a precise, taut, and stress-free state each time they move. This fundamentally eliminates the impact and vibration caused by relaxation during movement, enabling the follow-up cable chain, inlet hose, and return hose to accurately track the heat sink of the hatch in real time. This ensures that the inlet and return hoses always maintain the preset bending radius at bends, preventing obstruction or pressure pulsation caused by sudden changes in flow rate or local compression when transporting coolant. This guarantees the instantaneous response speed and long-term stability of the heat exchange equipment. Furthermore, it ensures that the inlet and return hoses maintain a consistent stress distribution after several cycles of movement, significantly extending their fatigue life and comprehensively improving operational reliability.

A connecting frame 4 is provided in front of the bottom surface of the support plate 1. A cabin heat sink 5 is provided on the bottom surface of the connecting frame 4. A bracket 6 is provided on the bottom surface of the cabin heat sink 5. A shaft shifting drive mechanism is provided in front of the bracket 6. A cabin door heat sink 7 that cooperates with the cabin heat sink 5 is provided on the shaft shifting drive mechanism. The top surface of the hatch heat sink 7 is provided with a linkage frame 8, and the top surface of the support plate 1 is provided with a movable plate 9 that moves back and forth. A follower cable chain is movably disposed between the support plate 1, the first side plate 2, and the second side plate 3. The fixed end of the follower cable chain is fixedly disposed on the inner wall of the second side plate 3 and located behind the moving plate 9. The movable end of the follower cable chain is located to the left of the moving plate 9 and in front of the fixed end of the follower cable chain. The follower cable chain is U-shaped and its opening faces the front of the support plate 1. A first liquid inlet plastic pipe 10, one end of which extends to the bottom end face of the support plate 1, and the other end of which is fixedly disposed above the fixed end of the following drag chain; a second liquid inlet plastic pipe 11, one end of which is connected to the front end face of the hatch heat sink 7, and the other end of which is located in front of the movable end of the following drag chain; a liquid inlet hose 12 is fixedly disposed above the inside of the following drag chain, and the liquid inlet hose 12 is connected to the first liquid inlet plastic pipe 10 and the second liquid inlet plastic pipe 11; The first return liquid plastic pipe 13 has one end connected to the front end face of the hatch heat sink 7, and the other end is located in front of the movable end of the following drag chain; the second return liquid plastic pipe 14 has one end extending to the bottom end face of the support plate 1, and the other end is fixedly disposed inside the lower part of the fixed end of the following drag chain; a return liquid hose 15 is fixedly disposed inside the lower part of the following drag chain, and the return liquid hose 15 connects the first return liquid plastic pipe 13 and the second return liquid plastic pipe 14; a fixing mechanism is provided between the second inlet liquid plastic pipe 11, the first return liquid plastic pipe 13, the linkage frame 8, and the moving plate 9.

[0028] One end of the first liquid inlet plastic pipe 10 and one end of the second liquid return plastic pipe 14 are connected to an external heat exchange device. The heat exchange device is located below the support plate 1 and transports cooling liquid. The shaft shift drive mechanism is used to drive the hatch door heat sink 7 forward to a predetermined position when the test piece and / or test equipment need to be installed in the heat sink 5 of the cabin body, so that the heat sink 7 of the hatch door is separated from the heat sink 5 of the cabin body to a predetermined degree so that the test piece and / or test equipment can be installed in the heat sink 5 of the cabin body. The shaft shift drive mechanism is used to drive the hatch heat sink 7 to move backward to the initial position after the test piece and / or test equipment are installed in the heat sink 5 of the cabin. During the movement of the door heat sink 7 forward to a predetermined position or backward to the initial position driven by the shaft-shifting drive mechanism, the movable end of the follow-up drag chain is continuously pulled or pushed forward or backward with the cooperation of the linkage frame 8, the moving plate 9, the fixing mechanism, the second liquid inlet plastic pipe 11, the first liquid return plastic pipe 13, the support plate 1, the first side plate 2, and the second side plate 3. This ensures that the liquid inlet hose 12 and the liquid return hose 15 simultaneously and accurately follow the door heat sink 7 forward or backward, and maintains the liquid inlet hose 12 and the liquid return hose 15 in real time. The vertical position of the 15 is maintained, and the inlet hose 12 and return hose 15 are kept in a U-shape with their openings facing the front of the support plate 1. This ensures that the heat sink 7 remains connected to the heat exchange equipment while the door heat sink 7 moves forward to the predetermined position or backward to the initial position, without needing to disconnect, thus ensuring uninterrupted testing, improving the continuity of the testing process, significantly increasing testing efficiency, and shortening the test preparation cycle. During the test, the inlet hose 12 and return hose 15 are prevented from being scattered, thus avoiding entanglement and friction that could lead to wear or leakage. This significantly improves the safety of the test, eliminating the need for manual handling and folding of the inlet hose 12 and return hose 15, and preventing damage to them due to human error. Furthermore, it provides continuous and stable guidance for the inlet hose 12 and return hose 15 as the door heat sink 7 moves forward to the predetermined position or backward to the initial position, preventing localized stress concentration or irregular deformation caused by free bending. This effectively reduces the risk of fatigue damage to the inlet hose 12 and return hose 15. Additionally, it suppresses disorderly swaying and shaking of the inlet hose 12 and return hose 15 as the door heat sink 7 moves forward to the predetermined position or backward to the initial position, preventing collisions or jamming with other components and significantly extending their service life.

[0029] It makes great use of vertical space and reduces the horizontal footprint, resulting in a more compact structure suitable for space-constrained testing environments; it greatly reduces the risk of leakage caused by mechanical vibration or impact and improves the reliability of long-term operation.
