Description

Technical Field

[0001] The utility model belongs to the technical field of meteorology and atmospheric physics, and in particular relates to a standard particle generation and measurement 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] In the cloud chamber, when particles pass through, they ionize the surrounding gas, forming visible tracks. These tracks can help researchers understand the properties, speed, momentum and other information of the particles. If a more comprehensive understanding of the behavior or characteristics of the particles is required, the position or angle of the particle generator can be adjusted to observe the particles multiple times in different positions or conditions. Through multiple observations, researchers can collect more data to more accurately analyze the behavior of the particles. And when observing particles inside the cloud chamber, it is usually necessary to install the particle generator on the top or side of the cloud chamber.

[0004] In the prior art, particle generators are usually installed in a fixed manner, and after installation, the relative position of the particle generator cannot be adjusted. Therefore, we propose a standard particle generation and measurement device to solve the above 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 standard particle generation and measurement device, comprising a cloud chamber assembly 1, a fixing assembly 4 mounted on the cloud chamber assembly 1, an adjusting assembly 3 mounted on the fixing assembly 4, and a particle generation assembly 2 mounted on the adjusting assembly 3;

[0028] The cloud chamber assembly 1 includes a cloud chamber body 11 and a sealing plate 15. The cloud chamber body 11 is configured as a hollow rectangular structure, and the sealing plate 15 is configured on the cloud chamber body 11.

[0029] The fixing assembly 4 includes a fixing block 41, a top plate 42, an insertion rod 43, a clamping block 44, a B hollow rod 45, a B spring 46 and a B telescopic rod 47. The fixing block 41 and the insertion rod 43 are both installed on the sealing plate 15. An insertion hole is provided on the fixing block 41, and the insertion rod 43 is arranged in the insertion hole. Two limiting grooves are provided on the insertion rod 43. The top plate 42 is installed on the fixing block 41, the B hollow rod 45 is installed on the top plate 42, the B spring 46 and the B telescopic rod 47 are both installed inside the B hollow rod 45, the B spring 46 is connected to the B telescopic rod 47, the clamping block 44 is installed on the B telescopic rod 47, and the top plate 42, the clamping block 44, the B hollow rod 45, the B spring 46 and the B telescopic rod 47 are all provided with two and symmetrically arranged, and the two clamping blocks 44 are both arranged in the limiting grooves.

[0030] Specifically, the particle generator is typically positioned in a fixed position within the cloud chamber to ensure stable and efficient particle generation and distribution. The specific location may vary depending on the cloud chamber design and experimental requirements, but generally, the particle generator is mounted on the top or side of the cloud chamber to ensure uniform distribution of particles throughout the entire space. Such a layout helps to ensure that the movement and trajectory of particles in the cloud chamber can be effectively observed and recorded. Since multiple particle generation is usually required to observe the trajectory generated after the particle movement, different particles can be observed multiple times at different positions or conditions, thereby more accurately analyzing the behavior of the particles. In specific use, the angle of the particle generating device itself is usually adjustable. This allows the generation angle of the particle generator to be adjusted during the specific observation period, thereby adjusting the movement angle of the particles, thereby realizing multi-position observation of the particles. However, since the particle generator is usually fixed, it is not convenient to adjust the height. In this embodiment, the height of the particle generating device can be adjusted through the particle generating component and the adjustment component, and combined with its own angle adjustment, the particles can be adjusted in multiple directions, thereby making the particle's movable trajectory richer, so that experimenters can collect more data and more accurately analyze the behavior of the particles.

[0031] Furthermore, in this embodiment, in order to be able to install the particle generating assembly 2 more stably, and after the installation is completed, if the height position of the particle generating assembly 2 needs to be adjusted during subsequent use, quick adjustments can be made, thereby changing the position of particle generation, thereby meeting different experimental needs.

[0032] Furthermore, when installing the particle generating assembly 2, the particle generating assembly 2 and the adjustment assembly 3 can be connected, and then the adjustment assembly 3 and the fixing assembly 4 can be connected. At this time, the fixing assembly 4 can be fixedly installed, so that the particle generating assembly 2 can be stably installed. When installing the fixing assembly 4, the insertion rod 43 can be fixedly connected to the sealing plate 15, and then the insertion rod 43 can be inserted into the insertion hole of the fixing block 41. Since the upper part of the insertion rod 43 is an arc structure, the upper end of the insertion rod 43 will push the clamping block 44 outward during insertion. At this time, the clamping block 44 and the B telescopic rod 47 will squeeze the B spring 46. After the insertion rod 43 is fully inserted, the clamping block 44 and the limiting groove are at the same height. At this time, the clamping block 44 will be inserted into the limiting groove under the elastic force of the B spring 46, so that the fixing block 41 can be fixed on the insertion rod 43 to prevent the fixing block 41 from being offset.

[0033] In this embodiment, the fixing assembly 4 further includes a B-link 48 . Two B-links 48 are provided, and both B-links 48 are rotatably provided on the fixing block 41 .

[0034] Specifically, in order to enable the adjustment component 3 and the fixing component 4 to be connected and to rotate during use, B-links 48 are provided at both ends of the fixing block 41 .

[0035] In this embodiment, the adjustment assembly 3 includes an A telescopic rod 35, an A hollow rod 36, an A spring 37, a B ratchet 38 and a B ratchet 39. The A hollow rod 36 is installed on the B connecting rod 48, the B ratchet 38 is installed on the B connecting rod 48, the B ratchet 39 is installed on the fixed block 41, and the B ratchet 38 and the B ratchet 39 are clamped. The A telescopic rod 35 and the A spring 37 are both installed inside the A hollow rod 36, and the A spring 37 is connected to the A telescopic rod 35.

[0036] Specifically, the A hollow rod 36 is fixedly connected to the fixed block 41, and the B ratchet 38 is fixedly set on the surface of the B connecting rod 48, and the B ratchet 39 is set on the fixed block 41. The B ratchet 39 can be used to clamp and limit the B ratchet 38, so that after the angle of the A hollow rod 36 and the B connecting rod 48 is adjusted, the angle of the B ratchet 38 can be fixed by the B ratchet 39, thereby avoiding the reverse deflection of the angle of the A hollow rod 36 at this time, and the A telescopic rod 35 and the A spring 37 are set in the A hollow rod 36. By setting the A spring 37 between the end of the A telescopic rod 35 and the inner wall of the A hollow rod 36, the A telescopic rod 35 and the A hollow rod 36 can be moved relative to each other, so that when the height position of the particle generating assembly 2 is adjusted later, the length between the A telescopic rod 35 and the A hollow rod 36 can be stretched or reduced, thereby meeting the height adjustment of the particle generating assembly 2.

[0037] In this embodiment, the adjustment component 3 also includes an adapter block 31, an A connecting rod 32, an A ratchet 33 and an A ratchet 34. The A connecting rod 32 is fixedly arranged on the particle generating component 2, the adapter block 31 is installed on the A telescopic rod 35, the A connecting rod 32 passes through and extends out of the surface of the adapter block 31, the A ratchet 33 is installed on the A connecting rod 32, the A ratchet 34 is installed on the adapter block 31, and the A ratchet 34 and the A ratchet 33 are clamped.

[0038] Specifically, in order to enable the particle generating assembly 2 and the adjustment assembly 3 to be connected, an A connecting rod 32 is installed on the particle generating assembly 2, and the A connecting rod 32 passes through and extends out of the surface of the adapter block 31, and an A ratchet 33 is also installed at the end of the A connecting rod 32, and an A ratchet 34 is installed on the adapter block 31. The A ratchet 33 can be clamped by the A ratchet 34, so that when the adapter block 31 and the particle generating assembly 2 are relatively deflected, the A ratchet 34 can clamp the A ratchet 33, so that the adapter block 31 and the particle generating assembly 2 maintain the deflection angle to avoid reverse rotation, and the adapter block 31 is installed at the end of the A telescopic rod 35, so that the particle generating assembly 2 can be connected to the fixing assembly 4 through the adjustment assembly 3.

[0039] In this embodiment, the particle generating assembly 2 includes a connecting block 21 and a particle generating device 22. The particle generating device 22 is installed on the connecting block 21. The connecting block 21 is configured as a rectangular structure. A rectangular groove is provided on the sealing plate 15, and the connecting block 21 is configured in the rectangular groove.

[0040] Specifically, in order to be able to stably set the particle generator 22 during specific use, the particle generator 22 can be set on the connecting block 21, and in specific use, the particle generator 22 can be set through the connecting block 21 as needed to connect with the outside world, and when in use, the connecting block 21 can be set in a rectangular groove, so that the particle generator 22 can be stably set.

[0041] In this embodiment, the particle generating assembly 2 also includes a screw rod 23 and a moving block 24. Two moving grooves are opened on the connecting block 21. There are two screw rods 23 and two moving blocks 24. The two screw rods 23 are installed in the rectangular groove, and the two screw rods 23 pass through and extend out of the surface of the connecting block 21. The two moving blocks 24 are respectively threaded on the screw rod 23, and the two moving blocks 24 are respectively installed in the moving grooves.

[0042] Specifically, when adjusting the position of the particle generator 22, the height of the particle generator 22 can be adjusted by changing the relative position between the adapter block 31 and the connecting block 21. During specific use, a screw rod 23 can be set in the movable groove, and a movable block 24 can be threaded on the screw rod 23. Since the A connecting rod 32 is installed on the movable block 24, the adapter block 31 can be relatively fixed to the movable block 24. At this time, the relative position between the adapter block 31 and the connecting block 21 can be changed by adjusting the height of the movable block 24, and then the height of the particle generator 22 can be adjusted.

[0043] Furthermore, during use, if the height of the connecting block 21 needs to be adjusted significantly, it can be achieved by changing the deflection angle of the adjustment component 3 between the particle generating component 2 and the fixed component 4. During specific use, the height position of the connecting block 21 and the particle generating device 22 can be changed by changing the angles of the adapter block 31, the A telescopic rod 35 and the A hollow rod 36.

[0044] In this embodiment, two adjusting assemblies 3 are provided, and the two A-connecting rods 32 are respectively installed on the moving block 24 .

[0045] Specifically, in order to make the connection between the particle generating component 2 and the fixing component 4 more stable, two sets of adjustment components 3 are set up so that the two can be stably connected. The two sets of adjustment components 3 can greatly change the height of the particle generating component 2, thereby meeting different experimental requirements.

[0046] In this embodiment, the cloud chamber assembly 1 also includes refrigerant A 12, a mist supply pipe 13 and refrigerant B 14. Refrigerant A 12 and refrigerant B 14 are both installed in the cloud chamber body 11, and the mist supply pipe 13 penetrates and extends out of the surface of the cloud chamber body 11 and refrigerant A 12.

[0047] Specifically, during use, mist can be supplied to the interior of the cloud chamber body 11 through the mist supply pipe 13 , and the temperature can be lowered by the refrigerant A 12 and the refrigerant B 14 .

[0048] The working principle and usage process of the present invention: When performing particle generation and measurement, since the particle generating device 22 needs to be installed in advance, the particle generating component 2 can be connected to the adjusting component 3, and then the adjusting component 3 can be connected to the fixing component 4, and then the fixing component 4 can be fixed to the upper end or side end of the cloud chamber component 1. At this time, the particle generating component 2 can be stably installed. In a specific experiment, if the position of the particle generating device 22 needs to be adjusted, when the positions of the adjusting component 3 and the fixing component 4 are relatively inconvenient, the position of the connecting block 21 and the particle generating device 22 can be slightly changed by rotating the screw rod 23. If the positions of the two need to be changed significantly, it can be achieved by adjusting the deflection angle of the adjusting component 3, thereby meeting different experimental needs.

[0049] The electronic components and modules used in the content of this utility model can be parts commonly used in the market that can realize the specific functions of this case, and the specific models and sizes can be selected and adjusted according to actual needs.
