[0001] The invention relates to the technical field of atmospheric science detection equipment, and in particular to a simple cloud chamber device for in-situ observation. Background Art

[0002] The cloud chamber is an important laboratory device for cloud and fog precipitation physics and has been widely used in cloud physics experimental research. The cloud chamber is a device that simulates cloud and fog conditions in a certain space and conducts different cloud physics experimental research. Depending on the size of the cloud chamber, different volumetric cloud physics experimental simulations and research can be achieved. Among them, the small hybrid cloud chamber with a volume of several to tens of liters is suitable for field natural ice core observations due to its small size, easy modification, strong controllability, and portability.

[0003] Similarly, due to the small size of the small cloud chamber, it is difficult to strictly control the temperature, the cold fog in the cloud chamber is maintained for a short time, and the fogging can easily cause disturbances in the gas sample volume, temperature and humidity in the cloud chamber.

[0004] Existing simple fog chambers usually use lifting components, steering components, and telescopic components to allow workers to observe the formation process of artificial ice nuclei in the fog chamber in real time. However, in this type of solution, the lifting components, steering components, and telescopic components are directly exposed to the fog, which inevitably disturbs the fog during operation. At the same time, the close-up observation lens is easily disturbed by the fog, resulting in low clarity of the shooting.

[0005] Based on this, the present invention proposes a simple cloud chamber device for in-situ observation, which can avoid disturbing the clouds and fog during the monitoring process while improving the clarity of the shooting. Summary of the invention

The top end of the adjusting rod is rotatably connected to the mounting sleeve, and the connection position divides the mounting sleeve into three equal parts. The camera is sleeved with the mounting sleeve, and the camera end points to the condensation platform. The signal transceiver is embedded in the bottom surface of the monitoring cavity, and the camera and the adjusting rod are electrically connected to the terminal through the signal transceiver.

[0012] As an improvement of the above technical solution, the cloud chamber body comprises at least: an inner shell and an outer shell, the gap between the inner shell and the outer shell constitutes a thermal insulation interlayer, the upper part of the thermal insulation interlayer is connected to the outside through a refrigerant outlet, and the lower part is connected to a supply device through a refrigerant inlet, the lower part of the inner shell is connected to an atomization inlet, the upper part of the inner shell has an aerosol inlet, and the bottom of the inner shell has a drain pipe.

[0016] As an improvement of the above technical solution, a temperature and humidity sensor for detecting internal temperature and humidity is provided inside the inner shell.

[0017] Beneficial effects of the present invention:

[0018] 1. Since the cover is sealed, the shooting component located in the monitoring inner cavity can not only clearly shoot the complete formation process of the condensation nucleus on the condensation platform, but also can observe from multiple angles in the monitoring inner cavity without disturbing the fog, making the process of condensation nucleus formation less disturbing.

The top of the adjustment rod is connected to the mounting sleeve in rotation, and the connection position divides the mounting sleeve into three equal parts, that is, the connection position of the top of the adjustment rod and the mounting sleeve is evenly distributed on the mounting sleeve.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Due to the small size of the small cloud chamber, it is difficult to strictly control the temperature, the cold fog in the cloud chamber is maintained for a short time, and the fogging can easily cause disturbances in the gas sample volume, temperature and humidity in the cloud chamber.

[0033] The existing technical solution uses the setting of lifting components, steering components and telescopic components to enable the staff to use in-situ observation technology to observe the artificial ice nucleus formation process in the cloud chamber from different angles and heights in real time. However, this solution still cannot avoid the disturbance of the lifting components, steering components and telescopic components to the clouds and fog during operation, and the clouds and fog will also affect the clarity of the shooting.

[0034] See also Figure 1-Figure 9 As shown, in order to solve the above technical problems, a technical solution for in-situ observation of a simple cloud chamber device is provided:

[0035] A simple cloud chamber device for in-situ observation includes: a cloud chamber body 100, a supporting ring plate 200, a cover body 300, a condensation platform 310, a monitoring inner cavity 320, a supporting rib plate 400 and a shooting assembly 500.

[0036] In one embodiment, the internal structure of the cloud chamber body 100 is changed.

[0037] See attached Figure 2 , Figure 4 and Figure 5As shown, first, a support ring plate 200 is installed inside the cloud chamber body 100. Preferably, the position of the support ring plate 200 inside the cloud chamber body 100 is adjustable so as to observe the formation of condensation nuclei at different heights. At the same time, a cover body 300 with a sealing structure is provided in the middle of the support ring plate 200. The support ring plate 200 is connected to the middle of the cover body 300 through a plurality of support ribs 400, that is, the support ribs 400 are distributed in a circle around the cover body 300, one end of which is connected to the middle of the cover body 300, and the other end is connected to the support ring plate 200, so as to keep the cover body 300 in a suspended state.

[0038] See attached Figure 6 and Figure 7 As shown, the upper part of the cover body 300 protrudes from the top surface of the support ring plate 200 and forms a condensation platform 310 of a transparent structure, and the lower part of the cover body 300 protrudes from the bottom surface of the support ring plate 200 and forms a monitoring inner cavity 320 of a light-proof structure. The monitoring inner cavity 320 has a shooting component 500 for shooting the condensation nucleus formation process from multiple angles. That is, the position of the condensation platform 310 is fixed, and the monitoring inner cavity 320 is located at the lower inner part of the cover body 300. Since the cover body 300 is sealed, the shooting component 500 located in the monitoring inner cavity 320 can not only clearly shoot the complete formation process of the condensation nucleus on the condensation platform 310, but also can observe from multiple angles in the monitoring inner cavity 320 without disturbing the fog, so that there are fewer interference factors in the process of condensation nucleus formation. In addition, the sealed environment also prevents the shooting component 500 from being affected by fog, ensuring the clarity of the shooting.

[0039] In one embodiment, the portion of the cover body 300 protruding from the top surface of the support ring plate 200 is a prism-shaped structure, the condensation platform 310 is the top surface of the portion of the cover body 300 protruding from the top surface of the support ring plate 200, the monitoring inner cavity 320 is a truncated cone-shaped structure, and the shooting assembly 500 is fixed in the monitoring inner cavity 320.

[0040] In one embodiment, the portion of the cover body 300 protruding from the top surface of the support ring plate 200 is a truncated cone structure, the condensation platform 310 is the top surface of the portion of the cover body 300 protruding from the top surface of the support ring plate 200, the monitoring inner cavity 320 is a truncated cone structure, and the shooting assembly 500 is fixed in the monitoring inner cavity 320.

[0041] To facilitate understanding of the technical solution of the present application, further description is given of the photographing assembly 500. The photographing assembly 500 is used to photograph the condensation nucleus formation process in real time and at multiple angles.

[0042] See attached Figure 8 and Fig. 9 As shown, in one embodiment, the shooting assembly 500 includes: a fixing base 510, an adjustment rod 520, a camera 530, a mounting sleeve 540 and a signal transceiver 550.

[0043] Further, the fixing seat 510 is set to be annular and fixed on the inclined inner wall of the monitoring inner cavity 320. The bottom end of the adjusting rod 520 is rotatably connected to the fixing seat 510, and the connection position divides the fixing seat 510 into three equal parts, that is, the connection position between the bottom end of the adjusting rod 520 and the fixing seat 510 is evenly distributed on the fixing seat 510. The bottom end of the adjusting rod 520 is rotatably connected to the fixing seat 510, that is, the adjusting rod 520 can rotate around the connection with the fixing seat 510, thereby realizing position adjustment.

[0044] In this embodiment, the adjustment rod 520 is a length-adjustable structure, preferably an electric telescopic rod, and the number of the adjustment rods 520 is three.

[0045] The top ends of the adjustment rods 520 are rotatably connected to the mounting sleeve 540, and the connection positions divide the mounting sleeve 540 into three equal parts, that is, the connection positions between the top ends of the adjustment rods 520 and the mounting sleeve 540 are evenly distributed on the mounting sleeve 540. Since the adjustment rods 520 and the fixing base 510 are also rotatably connected, the position change of the shooting assembly 500 inside the monitoring inner cavity 320 can be achieved by adjusting the length change of the three adjustment rods 520, including but not limited to approaching, moving away, tilting and rotating, so as to achieve multi-angle shooting.

[0046] The camera 530 is connected to the mounting sleeve 540 to facilitate the installation of the camera 530. The camera end of the camera 530 points to the condensation platform 310 to capture the formation of condensation nuclei.

[0047] In this solution, the camera 530 and the adjustment rod 520 are both wirelessly controlled, and the signal transceiver 550 is embedded in the bottom surface of the monitoring cavity 320. The camera 530 and the adjustment rod 520 are electrically connected to the terminal through the signal transceiver 550. They can be wirelessly controlled through the control terminal, which is more convenient to operate.

[0048] The above structure can effectively solve the problem of fog disturbance during the observation of condensation nucleus formation, which can not only reduce the interference factors of condensation nucleus formation, but also fix the position of condensation platform 310, and will not cause irregular changes in the formation process due to its own movement state. Since camera 530 is located in cover body 300, the shooting clarity of camera 530 is not affected by fog concentration, and clear shooting from multiple angles is achieved.

[0049] See attached Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the cloud chamber body 100 is improved.

[0050] The cloud chamber body 100 includes: an inner shell 110 , an outer shell 120 , a heat-insulating interlayer 130 , a refrigerant outlet 131 , a refrigerant inlet 132 , an atomization inlet 111 , an aerosol inlet 112 and a liquid discharge pipe 113 .

[0051] Specifically, the inner shell 110 is located inside the outer shell 120, and the two maintain a clearance fit, and the gap between the two constitutes a heat-insulating interlayer 130 for circulating and storing refrigerant. When working, the heat-insulating interlayer 130 is connected to the refrigerant supply device through the refrigerant outlet 131 at the upper part and the refrigerant inlet 132 at the lower part. When the cloud chamber body 100 is working, the refrigerant passing into the heat-insulating interlayer 130 can not only prevent the water mist from having a large temperature difference in the inner shell 110, but also form a kind of insulation layer, so that the heat inside and outside the inner shell 110 is isolated and not affected by the outside world.

[0052] In addition, a control valve for controlling the flow rate of the refrigerant is provided at the refrigerant inlet 132 to achieve control of different flow rates.

[0053] The inner shell 110 is connected to the atomizer generator through the atomizer inlet 111. Similarly, the inner shell 110 is connected to the aerosol generator through the aerosol inlet 112. During operation, the atomizer inlet 111 introduces mist into the inner shell 110 until it is supersaturated. When the mist meets the aerosol core material, it will cause water vapor to adhere to the aerosol core material to form tiny condensation nuclei, thereby simulating the situation where clouds and aerosol particles meet in the atmosphere. The drain pipe 113 is used to discharge the water condensed from the water vapor. At the same time, it can maintain the gap between the inner shell 110 and the outer shell 120 by fixedly connecting with the inner shell 110 and the outer shell 120.

[0054] See attached Figure 1 , Figure 3 and Figure 4 As shown, a negative pressure exhaust pipe 114 is also arranged on the top of the inner shell 110. The negative pressure exhaust pipe 114 is used to extract the air inside the inner shell 110 to reduce the pressure inside the inner shell 110. On the other hand, it can also be used to discharge the pre-heated air, and cooperate with the refrigerant in the thermal insulation interlayer 130 to achieve rapid cooling of the inner shell 110 and always maintain a low temperature.

[0055] Preferably, the volume flow rate of the negative pressure exhaust pipe 114 is smaller than the volume flow rate of the atomizing inlet 111, that is, the volume passing through the flow section per unit time, the negative pressure exhaust pipe 114 is greater than the volume flow rate of the atomizing inlet 111. Preferably, the negative pressure exhaust pipe 114 is one fifth of the volume flow rate of the atomizing inlet 111.

[0056] See attached Figure 2 , Figure 4 and Figure 6As shown, a ring-shaped cold light lamp 115 is arranged on the top surface of the inner shell 110 around the negative pressure exhaust pipe 114. The cold light lamp 115 is located directly above the cover 300, and a strip-shaped cold light lamp 2 116 is embedded on the top and bottom surfaces of the supporting rib plate 400. The cold light lamp 115 is mainly provided so that the camera 530 can clearly capture the complete formation process of the condensation nucleus on the condensation platform 310. At the same time, the cold light lamp 2 116 is used to realize the lighting around the condensation platform 310.

[0057] In this solution, the inner shell 110 is made of a transparent material, such as glass or transparent plastic. At the same time, an observation window 121 is provided at a position of the outer shell 120 corresponding to the cover 300. When simulating a cloud and fog test, the operator can observe the test conditions in the inner shell 110 through the observation window 121.

[0058] Preferably, two observation windows 121 are provided and symmetrically arranged on the circumferential outer wall of the outer shell 120 .

[0059] The inner shell 110 is made of transparent material, and an observation window 121 is provided on the outer shell 120 at a position corresponding to the cover body 300 .

[0060] The inner shell 110 has a temperature and humidity sensor 117 for detecting the internal temperature and humidity. The temperature and humidity sensor 117 is used to detect the temperature and humidity inside the inner shell 110 so as to adjust it according to the progress of the test.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
