[0044] The forward and backward movement device 4 has two main functions. The first is to ensure that the glass slide is moved to the appropriate position to collect ice crystal samples, and the second is to ensure that the samples are pushed out smoothly. When the forward and backward movement device 4 moves to the rear position, the glass slides 27 are all exposed, ensuring that the ice crystals fall evenly on the four top glass slides 27 so that the samples can be collected smoothly. When sampling is required, the forward and backward movement device 4 moves to the front position, and the entire set of equipment moves forward, so that the carrier box 24 is close to the discharge port 14, and the distance from the discharge port is 2mm to ensure that the ice crystal sample can be smoothly moved out. When sampling is completed, this part moves to the rear position, so that the carrier box 24 leaves the discharge port 14, ensuring that the internal sealing door can be closed smoothly.

[0045] like Figure 5As shown, the left and right moving device 3 includes left and right bottom plates 31, which are fixed on the vertical surface of the L-shaped connecting plate 19; two left and right end vertical plates 32 are fixed to the two ends of the left and right bottom plates 31, respectively, and two left and right support plates 33 are arranged between the two left and right end vertical plates 32, and the left and right support plates 33 are provided with threaded through holes, and the left and right end vertical plates 32 are provided with through holes; the outer sides of the left and right end vertical plates 32 are provided with left and right motor fixing plates 34 fixed to the left and right bottom plates 31, and the left and right stepping motors 35 are fixed on the left and right motor fixing plates 34, and the output shafts of the left and right stepping motors 35 are connected with left and right lead screws 36; the middle parts of the left and right lead screws 36 are threadedly connected to the threaded holes of the left and right support plates 33, and the two ends are rotatably connected to the through holes of the left and right end vertical plates 32, and when the left and right lead screws 36 rotate, the left and right support plates 33 are driven to move forward and backward; left and right guide rods 37 are also arranged next to the left and right lead screws 36.

[0046] The left and right support plates 33 are fixed with a glass slide box fixing plate 22, and the glass slide box 23 is fixed on the glass slide box fixing plate 22. Four glass slide boxes 24 are arranged in the glass slide box 23, and the bottom of the glass slide boxes 24 are respectively installed with glass slide limit switches 240, and the bottom of the feed inlet 15 is installed with a feed induction sheet. The glass slide limit switch 240 cooperates with the feed induction sheet to position the glass slide box 24. When the glass slide limit switch 240 is aligned with the induction sheet at the feed inlet, the position of the carrier box 24 and the feed inlet 15 can be aligned, thereby ensuring that the glass slide 27 can be smoothly pushed out. Ten glass slide holders 25 are arranged in the glass slide box 24, and a bottom bracket 26 is installed in each of the glass slide holders 25, and the glass slide 27 is installed in the bottom bracket 26. The function of the left and right moving device 3 is to adjust the position of the carrier box 24 by moving left and right, ensuring that the carrier box 24 is aligned with the discharge port 14, and ensuring that the ice crystal sample can be smoothly pushed out.

[0047] like Figure 6 and 7 As shown, a spring 241 is provided in the slide box 24, one end of the spring 241 is fixedly connected to the bottom of the slide box 24, and the other end is fixedly connected to a support plate 242, and a plurality of slide holders 25 are sequentially placed on the support plate 242; the bottom support 26 is pushed upward by the expansion and contraction of the spring 241, and the bottom support 26 pushes up the slides 27, and when the top slide 27 is pushed away, the bottom slide 27 bounces up, thereby ensuring that all slides 27 in the slide box 24 can be pushed out. The tops of the two sides of the slide box 24 extend relatively to form a limiting plate 243, and the limiting plate 243 is used to limit the slide holder 25.

When the ejection screw rod 206 rotates, it drives the ejection support plate 203 to move forward and backward; a push rod 208 is fixed on the ejection support plate 203. When the ejection support plate 203 moves forward, the push rod 208 moves forward to push the slide 27 from the feed port 15 to the discharge port 14; a ejection guide rod 207 is also arranged next to the ejection screw rod 206. The ejection mechanism 2 pushes the ice crystal sample from the feed port end inside the cloud chamber to the discharge port end outside the cloud chamber.

[0049] The constant air pressure and gas composition inside the cabin of the cloud chamber 1 are ensured by the inner and outer sealing door parts, which all adopt the compression static sealing method. A rubber layer of a certain thickness is installed on the sealing surface of the sealing door plate. The sealing door is driven by an electric push rod, which presses the inner and outer sealing doors tightly against the discharge port or the feed port respectively. The cabin sealing door can only open one door at a time, and the other door must be closed, so as to ensure that the cabin is separated from the outside at any time, so as to ensure the constant composition inside the cabin. The control system for ice crystal sampling is placed next to the outdoor discharge port 14, which can control the movement of the left and right moving device 3 and the ejection mechanism 2 on the forward and backward device 4, and also control the opening and closing of the inner and outer sealing doors, and ensure that only one side can be opened to ensure the indoor sealing. At the same time, the previously collected information can be sorted and printed according to needs. It has a large-capacity storage system that can store at least 10 years of operation information. At the same time, the touch screen technology is used to make the control operation concise and clear. The operator can control the system operation with just a light touch. When sampling is required, the inner sealed door 9 is opened first, and then the whole set of equipment moves forward, the left and right moving device 3 aligns the carrier box 24 with the feed port 15, and then the pushing mechanism 2 pushes the ice crystal sample out of the cabin, and then the push rod is retracted, the whole set of equipment moves backward, the inner sealed door 9 is closed, and then the outer sealed door 8 is opened, the slide 27 is manually taken away from the outside, and then the outer sealed door 8 is closed, and then the next sampling action is carried out in sequence.

[0050] The cloud chamber and sampling device provided by the present invention can effectively protect ice crystal samples from being damaged, reduce ice crystal condensation in the laboratory, ensure the airtightness and thermal insulation of the cloud chamber environment, and facilitate detection and recording. Protect ice crystal samples: The mobile transmission part of the device can move forward or backward as a whole. When the whole part moves to the rear position, the entire surface of the slide 27 is exposed, ensuring that ice crystals fall evenly on the slide 27 so that samples can be collected smoothly. When sampling is required, the device moves forward as a whole, so that the carrier box ice crystal sample can be smoothly pushed into the feed port, and ensure that the ice crystals will not touch the discharge port 14 during the removal of the slide. Sealing: The air pressure, temperature and humidity inside the cloud chamber need to be kept constant, so the impact of the sampling process on the room should be minimized. The equipment is designed with two sets of inner and outer sealing doors. Both sets of sealing doors are designed as compression-type static seals. A certain thickness of low-temperature resistant rubber sheet is installed on the sealing surface of the sealing door plate. The sealing door drive is realized by an electric push rod, which presses the inner and outer sealing doors tightly against the discharge port or the feed port. During the sampling process, only one of the cabin sealing doors is opened at a time, and the other door is closed to ensure that the room is separated from the outside at any time, thereby reducing the impact of sampling on the indoor temperature, humidity and air pressure. Reduce condensation: The ice crystal sampling equipment is made of stainless steel shells, and all shells are designed to be arc-shaped as much as possible to reduce condensation and frost. Insulation: Except for the surface where the discharge port is located, all other parts of the equipment cabin are trapped in the insulation layer of the cabin outer wall to minimize heat loss. Convenient detection and recording: The main function of the equipment is to control the uninterrupted sampling and automatic warehouse exit of ice crystal slides. It solves the errors caused by manual operation in the past. Automatic sampling and automatic storage make the operation simple. The control system records the collection time in real time for future reference.
