Description

Technical Field

[0001] The invention relates to the technical field of thermal vacuum experiments, and in particular to a continuous satellite thermal vacuum experiment device. Background Art

[0002] Thermal vacuum experiments refer to thermal experiments conducted in a vacuum environment, which are usually used to study the behavior of materials under extreme temperature and pressure conditions. Such experiments are widely used in aerospace, materials science, physics and other fields.

[0003] Existing satellite thermal vacuum test equipment often generates the target ambient temperature by transporting flowing liquid nitrogen and hot oil inside the tank. However, since the tank is unchanging, when the required experimental ambient temperature changes, the energy of the liquid nitrogen and hot oil will be neutralized inside the tank, which will not only increase the preparation time of the experiment but also cause energy loss problems for the liquid nitrogen and hot oil. Summary of the invention

[0004] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to realize remote operation of different heat-conducting components corresponding to different experimental environments through the design of heat-conducting component partitions, and solve the problem that the existing satellite thermal vacuum test device often generates the target ambient temperature by transporting flowing liquid nitrogen and hot oil inside the tank body, but because the tank body is unchanged, when the required experimental ambient temperature changes, the energy of liquid nitrogen and hot oil will be neutralized inside the tank body, which will not only increase the preparation time of the experiment but also cause the energy loss of liquid nitrogen and hot oil. The present invention achieves the above purpose through the following technical solutions:

The fixed partitions are semicircular ring structures and are arranged opposite to each other on both sides of the guide tube one.

[0008] Preferably, the movable baffle 1, movable baffle 2 and movable baffle 3 are all semicircular ring structures, two of which are provided, and are arranged opposite to each other on both sides of the guide pipe 1 to form an approximately full circle structure.

One side of the guide tube 1 located at the bottom is fixed on the upper wall surface of the base plate through a connecting rod, and the other side is connected to the guide tube 2. The two guide tubes 1 respectively contain the delivery pipelines of two storage tanks 2 and two storage tanks 1.

The distance moved is the same as the width of the heat-conducting ring of the conduction block, the width of the protrusion, and the width of the isolation zone. The heat-conducting ring of the conduction block overlaps with the protrusion in the experimental environment, so that during the transition between the low-temperature experimental environment and the high-temperature experimental environment, the heat-conducting ring of the conduction block will also be converted, that is, the heat-conducting ring of the conduction block that overlaps with the protrusion in the original experimental environment will be driven by the electric telescopic rod to move to the isolation zone position between two adjacent protrusions after the experimental environment is changed; thereafter, the residual energy of the heat-conducting ring of the conduction block cannot continue to be transferred to the protrusion, and on the other hand, the heat-insulating material that blocks the heat energy transfer is provided at the connection of multiple heat-conducting rings, which will also reduce the influence of energy transfer to adjacent heat-conducting rings;

[0017] 3. The raised separation arrangement and the conduction block being composed of a plurality of heat-conducting rings and the connection of the plurality of rings being provided with heat-insulating materials for blocking the transfer of heat energy can effectively reduce the problem of energy loss caused by the mutual neutralization of the hot oil and liquid nitrogen energy when multiple experiments are carried out alternately.

[0050] like Figure 5-10 As shown, the regulating device 500 includes: a guide tube 1 510, an upper guide port 1 520, an upper guide port 2 530, an elastic telescopic rod 540, a guide tube 2 550, a moving rod 560, a lower guide port 1 570, and a lower guide port 2 580;

[0052] The plurality of upper flow guide ports 520 are arranged on the flow guide pipe 510;

[0053] The plurality of upper guide ports 530 are arranged on the guide pipe 1 510 located above; the upper guide port 1 520 and the upper guide port 2 530 are respectively connected to the delivery pipelines of the two storage tanks 1000; the upper guide port 1 520 and the upper guide port 2 530 are arranged adjacent to each other on the guide pipe 1 510; the upper guide port 2 530 is used for discharging liquid nitrogen, and the upper guide port 1 520 is responsible for the reflux of liquid nitrogen;

[0060] The protrusions 720 are arranged in a plurality of ring shapes on the outer wall of the ring-shaped housing 710, and mainly play a role in conducting energy in specific implementation;

[0061] The isolation zone 730 is a partition space, which is mainly arranged between the protrusions 720 on the conductive block 410, so as to form a gap between the conductive block 410 and the annular shell 710 to prevent the residual energy on the conductive block 410 from continuing to be transmitted to the annular shell 710; the width of the isolation zone 730 between adjacent protrusions 720 is the same as the width of the protrusion 720 and the width of the heat conductive ring of the conductive block 410.

[0062] Working principle of the present invention:

[0063] like Figure 1-4 As shown, when a vacuum thermal test is performed on a satellite, the box door 900 is first opened to transport the object to be tested into the shell device 700. Then, after the box door 900 is closed, the exhaust device 300 is started to exhaust the air inside the shell device 700 to make it reach a vacuum state in preparation for the experiment.

[0064] When a low temperature experiment is required, the electric telescopic rod 800 contracts to drive the guide tube 1 510 to move, and the guide tube 1 510 drives the movable partition 2 440 on it to move closer to the electric telescopic rod 800, so that the movable partition 2 440, the movable partition 3 450 and the fixed partition 420 are attached together. Figure 6 At this time, the movable partition 1 430 is blocked by the left positioning block 460 and cannot move the same distance with the fixed partition 420, which makes the distance between the fixed partition 420 and the movable partition 1 430 smaller than the distance between the movable partition 1 430 and the movable partition 2 440;

[0065] At the same time, the upper guide port 1 520 will be located exactly between the movable partition 1 430 and the movable partition 2 440, and the upper guide port 2 530 will be located between the fixed partition 420 and the movable partition 1 430; then, driven by the built-in pump of the storage tank 2 1000, the liquid nitrogen is discharged from the upper guide port 2 530 into the space between the fixed partition 420 and the movable partition 1 430. Since the spacing between the above partitions is small, the liquid nitrogen can quickly fill the space between the two partitions, thereby avoiding the problem that when the liquid nitrogen is added from the top to the bottom, the liquid nitrogen will be preferentially gathered at the lower part of the outer wall of the vacuum tank due to its own gravity, resulting in a temperature difference between the upper and lower ends of the vacuum tank in the early stage;

[0066] A small hole is provided at the bottom of the movable partition 1 430, so that the liquid nitrogen at the bottom between the fixed partition 420 and the movable partition 1 430 can flow through the small hole into the space between the movable partition 1 430 and the movable partition 2 440 and finally flow back to the storage tank 2 1000 through the upper guide port 1 520 to wait for further processing and application;

[0067] When a high temperature experiment is required, the electric telescopic rod 800 drives the guide tube 1 510 to move in the reverse direction and reset, driving the movable partition 2 440 to move away from the electric telescopic rod 800, so that the movable partition 2 440, the movable partition 1 430 and the fixed partition 420 are attached together; at this time, the distance between the fixed partition 420 and the movable partition 3 450 is smaller than the distance between the movable partition 3 450 and the movable partition 2 440 due to the blocking of the positioning block 460;

[0068] At the same time, the lower guide port 1 570 will be located exactly between the movable partition 3 450 and the movable partition 2 440, and the lower guide port 2 580 will be located between the fixed partition 420 and the movable partition 3 450; then, driven by the built-in pump of the storage tank 1 600, the hot oil is discharged from the lower guide port 2 580 into the space between the fixed partition 420 and the movable partition 3 450, and a small hole is provided on the top of the movable partition 3 450, so that the hot oil at the bottom between the fixed partition 420 and the movable partition 3 450 can flow through the small hole into the space between the movable partition 3 450 and the movable partition 2 440 and finally flow back to the storage tank 1 600 through the lower guide port 1 570;

[0069] The energy of the hot oil and liquid nitrogen is transferred to the protrusion 720 through the conductive block 410, and then transferred to the annular housing 710 through the protrusion 720 to form a target temperature environment; in specific implementation, the electric telescopic rod 800 drives the guide tube 1 510 and the conductive block 410 to move from a low-temperature experimental environment to a high-temperature experimental environment. The distance moved is the same as the width of the heat-conducting ring of the conductive block 410, the width of the protrusion 720, and the width of the isolation zone 730, and the heat-conducting ring of the conductive block 410 in the experimental environment coincides with the protrusion 720;

[0070] This allows the heat-conducting ring of the conductive block 410 to be transformed during the transition between the low-temperature experimental environment and the high-temperature experimental environment, that is, the heat-conducting ring of the conductive block 410 that overlaps with the protrusion 720 in the original experimental environment will be driven by the electric telescopic rod 800 to move to the isolation zone 730 after the experimental environment is changed;

[0071] Afterwards, on the one hand, the residual energy of the heat-conducting circle of the conduction block 410 cannot continue to be transferred to the protrusion 720. On the other hand, the influence of the heat-conducting material that blocks the heat energy transfer arranged at the connection between the multiple heat-conducting rings will also reduce the influence of energy transfer to the adjacent heat-conducting rings. The above-mentioned segmented arrangement of the protrusions 720 and the partitioned arrangement of the heat-conducting rings of the conduction block 410 can effectively reduce the problem of energy loss caused by the mutual neutralization of hot oil and liquid nitrogen energy when multiple experiments are carried out alternately.
