Description

Technical Field

[0001] The utility model belongs to the technical field of meteorology and atmospheric physics, and particularly relates to a cloud chamber wall temperature measurement and control device. Background Art

[0002] The catalytic performance of catalysts used for artificial rainfall enhancement directly impacts the effectiveness of weather modification. Depending on the nature of the cloud, rainfall enhancement can be categorized as cold cloud catalysis, mixed cloud catalysis, and warm cloud catalysis. Catalysts are categorized as cold cloud catalysts and hygroscopic catalysts. The ice-forming performance of cold cloud catalysts can only be tested on-site using indoor cloud chambers to simulate cloud and fog. Cloud chambers are commonly used for research on catalyst ice-forming performance, new catalyst development, catalyst operational testing, and the impact of long-term storage on catalyst performance.

[0003] During a cloud chamber experiment, when it is necessary to inject a catalyst into the interior of the cloud chamber, it is usually necessary to measure the temperature of the inner wall of the cloud chamber first, and then inject the catalyst after the temperature of the cloud chamber drops to a suitable temperature, so as to avoid the catalyst being affected by the temperature of the inner wall of the cloud chamber, so that the catalyst cannot be dispersed more evenly in the cloud chamber, thereby affecting the subsequent cloud chamber experiment. When measuring the wall temperature of the cloud chamber, it is usually necessary to measure its temperature distribution. This requires adjusting the position of the temperature measuring device during the measurement to meet the measurement requirements, and because the temperature measuring device needs to be close to the inner wall of the cloud chamber during the measurement of the wall temperature of the cloud chamber to perform more accurate measurements, it is necessary to move the temperature measuring device to the area to be measured during the specific measurement, and then measure the temperature of the inner wall of the cloud chamber in the area through the temperature measuring device. For this reason, we propose a cloud chamber wall temperature measurement and control device to solve the above-mentioned problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-6 The utility model provides a cloud chamber wall temperature measurement and control device, comprising a cloud chamber component 1 and an injection component 2, wherein the injection component 2 is mounted on the cloud chamber component 1, and further comprising a vertical adjustment component 3 mounted in the cloud chamber component 1, a horizontal adjustment component 4 mounted on the vertical adjustment component 3, and a temperature measuring device 5 mounted on the horizontal adjustment component 4;

[0028] The cloud chamber assembly 1 includes a cloud chamber body 11 and a partition 12. The cloud chamber body 11 is hollow inside, and the partition 12 is fixedly arranged inside the cloud chamber body 11.

[0029] The vertical adjustment assembly 3 includes a screw rod 31, a fixed cross piece 32, a limit rod 33 and a movable disk 34. The fixed cross piece 32 is fixedly arranged inside the cloud chamber body 11. A rotating hole is opened on the partition 12. The screw rod 31 is installed in the rotating hole, and the screw rod 31 is connected to the fixed cross piece 32. Two limit rods 33 are provided, and the two limit rods 33 are installed between the partition 12 and the fixed cross piece 32. The movable disk 34 is threaded on the screw rod 31, and the movable disk 34 is installed on the two limit rods 33.

[0030] Specifically, when measuring the temperature of the inner wall of the cloud chamber, first, ensure that the cloud chamber is closed and free of fog. Next, cool the refrigerant to a certain temperature (e.g., -25°C or -26°C) and shut down the system. Temperature measurement points are placed at different locations in the cloud chamber to measure the temperature distribution in both the horizontal and vertical directions.

[0031] For horizontal temperature distribution measurements, start at a certain height (e.g., 90 cm) from the bottom of the cloud chamber. Position the temperature measuring device 5 from the inner wall of the cloud chamber, moving horizontally a certain distance (e.g., 10 cm or 15 cm) to create a measuring point. The device then pauses at each measuring point for a certain amount of time (e.g., 2 minutes or 1 minute) to take a reading. This allows for obtaining horizontal temperature distribution data within the cloud chamber.

[0032] For vertical temperature distribution measurement, you can start at the center of the cloud chamber, a certain distance from the bottom of the cloud chamber (e.g., 10 cm). Each time the temperature measuring device 5 rises vertically a certain distance (e.g., 10 cm or 5 cm), it becomes a measuring point. The temperature measurement device 5 stays at each measuring point for a certain amount of time to take a reading. This way, you can obtain vertical temperature distribution data for the cloud chamber.

[0033] Furthermore, in this embodiment, in order to be able to perform multiple and sufficient temperature measurements on the inner wall of the cloud chamber body 11, the height of the temperature measuring device 5 can be changed by rotating the screw rod 31. When the screw rod 31 is rotated, the movable disk 34 will move up and down under the limit of the two limit rods 33. Since the horizontal adjustment component 4 is arranged on the movable disk 34, and the temperature measuring device 5 is arranged on the horizontal adjustment component 4, the horizontal adjustment component 4 and the temperature measuring device 5 can move vertically at this time, and then the vertical temperature distribution inside the cloud chamber body 11 can be measured. During the measurement, in order to enable the screw rod 31 and the limit rod 33 to be stably set, the two are connected to the fixed cross piece 32.

[0034] Furthermore, when measuring the horizontal temperature distribution inside the cloud chamber body 11, the horizontal adjustment component 4 can be operated to drive the temperature measuring device 5 to rotate in the horizontal direction. At this time, the horizontal temperature distribution inside the cloud chamber body 11 can be measured through the above-mentioned temperature measurement operation.

[0035] In this embodiment, the cloud chamber assembly 1 further includes a support member 13 . A plurality of support members 13 are provided. The plurality of support members 13 are all mounted on the cloud chamber body 11 . The cloud chamber body 11 is provided with a connection hole.

Then, the A motor 35 can be run to drive the movable disk 34 to be adjusted in height.

[0042] In this embodiment, the horizontal adjustment component 4 includes a rectangular member 41, a bevel gear 42, a rotating member 43 and a connecting rod 45. There are two connecting rods 45, and the two connecting rods 45 are both installed on the movable disk 34. The rotating member 43 is rotatably set on the two connecting rods 45. There are two rectangular members 41 and two bevel gears 42. The two rectangular members 41 are both installed on the movable disk 34. The two bevel gears 42 are rotatably set on the rectangular member 41 respectively, and the two bevel gears 42 are symmetrically arranged.

[0043] Specifically, when measuring the horizontal temperature distribution inside the cloud chamber body 11, in order to meet the above-mentioned measurement requirements, a horizontal adjustment component 4 is installed on the movable disk 34. During use, by fixing two rectangular parts 41 and a connecting rod 45 on the movable disk 34, the bevel gear 42 and the rotating part 43 can be stably installed.

[0044] In this embodiment, the horizontal adjustment assembly 4 further includes a B motor 44 . The B motor 44 is mounted on the movable plate 34 , and an output end of the B motor 44 is connected to the bevel gear 42 .
