It can provide an ultra-low temperature constant temperature supply of -100-105 degrees Celsius to simulate the high-altitude low-temperature test environment conditions. At the same time, the temperature control method is simple and reliable, and the response speed is sensitive and efficient.

[0004] During the research process of the above-mentioned existing technology, it is necessary to measure the dynamic ambient temperature in order to quickly record the temperature changes of specific physical phenomena in a very short time. Temperature measuring points need to be arranged in the cloud chamber.

A large number of temperature sensor connection lines will be used, which will occupy the space inside the cloud chamber and the installation is cumbersome. After the temperature sensor is installed, it can only monitor the temperature measuring points and cannot comprehensively monitor the temperature of all positions in the cloud chamber.

[0027] In this embodiment, a slide groove 9 is provided at the bottom of the adjusting disk 6, and the adjusting assembly 8 includes a screw 81 rotatably set in the slide groove 9, a moving block 82 threadedly connected to the outer wall of the screw 81, a servo motor 83 fixedly set above the adjusting disk 6, a worm 84 fixedly connected to the output shaft of the servo motor 83, and a worm wheel 85 fixedly sleeved on the outer wall of the screw 81 and meshing with the worm 84; the servo motor 83 drives the worm 84 to rotate to rotate the worm wheel 85, and the rotation of the worm wheel 85 can drive the screw 81 to rotate. The screw 81 drives the moving block 82 to drive the column 3 through threaded transmission to adjust the position of the temperature sensor 4.

[0028] In this embodiment, the rotating assembly 7 includes a box body 71 fixedly connected to the outer wall of the cloud chamber 1 and communicated with the cloud chamber 1, a driving motor 72 fixedly installed above the box body 71, a gear 73 fixedly sleeved on the output shaft of the driving motor 72 and located in the box body 71, and a gear ring 74 fixedly sleeved on the outer wall of the adjusting disk 6 and meshing with the gear 73; the gear 73 is rotated by the driving motor 72, and the rotation of the gear 73 cooperates with the gear ring 74 to make the gear ring 74 drive the adjusting disk 6 to rotate, thereby further adjusting the position of the temperature sensor 4.

[0029] In this embodiment, a position sensor 10 is installed on the column 3, and the temperature sensor 4 and the position sensor 10 are electrically connected to the controller 2 for position and temperature monitoring; the temperature sensor 4 transmits the monitored temperature to the controller 2, and the position sensor 10 transmits the planar position of the temperature sensor 4 to the controller 2.

[0030] In this embodiment, the side view cross-sections of the slide groove 9 and the movable block 82 are both "I"-shaped, and the side view cross-section of the movable block 82 is "convex"-shaped. The movable block 82 can slide along the length direction of the slide groove 9; the movable block 82 and the slide groove 9 are limited by the cooperation of the movable block 82, so that the movable block 82 moves in a straight line along the slide groove 9.

[0031] In this embodiment, the interior of the slide groove 9 is fixedly connected to the limit bar 11 , and the worm gear 85 and the moving block 82 are respectively located on both sides of the limit bar 11 ; the limit bar 11 can separate the moving bar and the worm gear 85 .

[0032] In this embodiment, the length of the slide groove 9 is greater than the radius of the adjustment disk 6, the distance between the side of the limit bar 11 away from the worm gear 85 and the inner wall of the slide groove 9 is greater than the radius of the adjustment disk 6, and the moving path of the moving block 82 is greater than the radius of the adjustment disk 6; so that the stroke of the moving block 82 can be greater than the radius of the adjustment disk 6, realizing all-round monitoring.

[0033] In this embodiment, the ratio of the number of teeth of the gear 73 to the number of teeth of the gear ring 74 is 1:6, thereby achieving smaller angle adjustment of the adjustment disk 6 .

[0034] The usage and working principle of this device: When the device is in use, multiple temperature sensors 4 on the column 3 monitor the temperature at different positions in the height direction. When it is necessary to monitor the temperature at other positions in the cloud chamber 1, the servo motor 83 and the drive motor 72 are turned on. The servo motor 83 drives the worm 84 to rotate to rotate the worm gear 85. The rotation of the worm gear 85 can drive the screw 81 to rotate. The screw 81 causes the moving block 82 to drive the column 3 to move through the thread transmission. The drive motor 72 rotates the gear 73. The rotation of the gear 73 cooperates with the gear ring 74 to cause the gear ring 74 to drive the adjustment disk 6 to rotate, so that the column 3 follows the adjustment disk 6 to adjust the angle. The column 3 can also rotate while following the movement of the moving block 82. Therefore, the horizontal plane of the adjustable position of the column 3 can cover the entire cross-section of the cloud chamber 1. In combination with the multiple temperature sensors 4 on the column 3, temperature monitoring can be performed at different positions in the internal space of the cloud chamber 1, reducing the layout of the temperature sensors 4 and connecting lines, increasing the range of temperature monitoring, and realizing the monitoring of the spatial distribution of temperature in the cloud chamber 1.
