[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0031] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0032] Example 1
[0033] A cloud particle collection device for meteorological detection provided in Example 1 of this specification is provided. Figure 1 and Figure 2 As shown, it includes a particle capturing platform 1 and an image acquisition device 2.
[0034] Among them, the particle capture platform 1 is used to capture cloud particles; the image acquisition device 2 is used to collect the captured cloud particle images and transmit the cloud particle images to the background.
[0035] In a possible implementation, the particle capture platform 1 includes a transparent plate 11 and a grease brush 12 movably disposed on the transparent plate. The grease brush 12 can apply a grease layer on the transparent plate and can scrape off the cloud particles on the transparent plate 11. In a specific implementation, the transparent plate is made of transparent material (plastic, glass) to receive cloud droplets (water droplets, ice droplets). Figure 3 and Figure 4As shown, the grease brush 12 includes a first oil box 121, an oil filling hole 122 is provided on the first oil box 121, there is a gap between the bottom of the first oil box 121 and the transparent plate 11, a first oil outlet slit 123 is opened at the bottom of one side of the first oil box 121 along the length direction, and the horizontal height of the oil filling hole 122 is greater than the horizontal height of the first oil outlet slit 123; a brush plate 124 is provided on the first oil box 121, the brush plate 124 is an elastic plate, the brush plate 124 and the first oil outlet slit 123 are arranged on the same side of the first oil box 121, and the bottom of the brush plate 124 is in contact with the transparent plate 11; the brush plate 124 can close or open the first oil outlet slit 123. The grease in the first oil box includes but is not limited to silicone oil. Further explanation, the bottom of the first oil box 121 is inclined to the side of the first oil outlet slit 123 to form a sharp angle structure, which reduces the dead corner of the first oil box, thereby reducing the accumulation of grease in the first oil box and improving the utilization rate of grease. The oil filling hole is set at the top of the first oil box.
[0036] In a preferred implementation, please continue to refer to Figure 3 and Figure 4 As shown, the brush plate 124 is mounted on the first oil box 121 through the mounting plate 125, the fixing section of the brush plate 124 is provided with a mounting hole, the mounting plate is provided with a bolt hole corresponding to the mounting hole, and the mounting plate is connected to the first oil box through a fastening bolt. It is convenient to replace the brush plate. At the same time, the brush plate is fixed.
[0037] The driving device can drive the grease brush to move on the transparent plate. In a possible implementation, the driving device includes a servo servo 13 vertically mounted on the transparent plate 11, and a servo rocker arm 14 is horizontally connected to the output shaft of the servo servo 13, and the servo rocker arm 14 is connected to the grease brush 12. When in use, the servo servo is started, and the output shaft of the servo servo rotates to drive the servo rocker arm to rotate, thereby driving the grease brush to rotate.
[0038] The image acquisition device includes a camera 21 for collecting and capturing cloud particle images; and an image transmitter 22, which is connected to the camera data and is used for long-distance transmission of cloud particle images.
[0039] This embodiment can capture cloud droplets through a transparent plate brushed with grease, and cloud droplets (water droplets) falling on the transparent plate can be captured by an ordinary camera, without the need for a high-speed camera to shoot cloud droplets, which greatly reduces costs and is suitable for promotion and use. The overall structure is simple, the weight is light, and it is easy to operate.
[0040] In a preferred implementation, see Figure 5As shown, the grease brush includes a second oil box 131, the bottom cross-section of the second oil box 131 is a trapezoidal structure that is wide at the top and narrow at the bottom, and a second oil outlet slit 132 is provided at the bottom of the second oil box. When in use, when the servo rocker arm moves, such as moving clockwise first, the front edge of the oil brush pushes the water droplets to one side, grease seeps out of the bottom of the oil box, the rocker arm moves counterclockwise, and the oil brush further applies oil to the transparent plate. It should be noted that in order to better discharge the oil, a gap of 0.1-0.33mm is set between the second oil box and the transparent plate. When in use, the grease can be relied on to have a viscosity. When the grease discharges to fill the gap, it will stop discharging oil and will not leak out, which can improve the efficiency of brushing the oil.
[0041] Example 2
[0042] A method for using a cloud particle collection device for meteorological detection provided in Example 2 of this specification is described in detail in Figure 6 , Figure 7 and Figure 8 As shown, the following steps are included:
[0043] S1, the grease brush is driven to move to the left by the driving device, and the grease brush greases the transparent plate;
[0044] S2, collecting the falling cloud droplets through a transparent plate brushed with grease;
[0045] S3, acquiring cloud droplet images through an image acquisition device;
[0046] S4, then the driving device drives the grease brush to move rightward to scrape off the collected cloud droplets;
[0047] S5. Repeat the above steps S1-S4 to perform continuous collection.
[0048] In a possible specific implementation, the transparent plate is coated with grease (such as silicone oil), and the grease is used to prevent cloud droplets from splashing. Fig. 9 This is the image of a water drop in the cloud just falling onto the transparent plate. Fig.10 The image of a water droplet falling on a transparent plate after being stabilized. When a water droplet from a cloud falls on a transparent plate coated with grease, the water droplet spreads out due to the impact force ( Fig. 9 ), and then under the action of silicone oil, the water shrinks into water droplets ( Fig.10 ). After coating the transparent plate with silicone oil, the water droplets will not splash and can be restored to water droplets, solving the problem of capturing cloud droplets with ordinary cameras. The lack of high-speed cameras greatly reduces the cost of the instrument, making the detection of particles in clouds more widely applicable.
[0049] The grease brush is a first oil box with a first oil outlet slit, into which grease is injected (filled). The grease brush is installed on the rocker arm of the servo steering gear. The rotation of the rocker arm drives the grease brush to move on the transparent plate, scraping away the cloud droplets while oozing grease from the gap to grease the transparent plate. The control circuit also includes a single-chip microcomputer, which generates a periodic pulse signal to control the steering gear to periodically rotate the rocker arm, for example, the rocker arm rotates once every 10 seconds, and the rocker arm rotates by about 90 degrees.
[0050] The brush plate is a sheet of soft material, such as a silicone sheet. The brush plate fits with the first oil box under the action of gravity and has a blocking effect on the oil in the grease box. Figure 7 and Figure 8 As shown, when the grease brush moves to the right, due to the resistance of the transparent plate, the brush plate is closely attached to the first oil box, preventing the grease from flowing out, and pushing away the water droplets on the transparent plate to remove the water droplets on the transparent plate. When moving to the left, the lower part of the brush plate is no longer supported by the first oil box. Under the resistance of the transparent plate, the lower end slightly leaves the first oil box, and the grease flows out more easily, and the transparent plate is coated with grease during the movement.
[0051] Ordinary cameras usually capture 20-50 frames of images per second. Since cloud droplets are moving, directly photographing cloud droplets with a camera will result in low capture rate and unclear images. Therefore, the method of capturing first and then photographing is adopted. That is, the cloud droplet capture platform is used to receive the cloud droplets, and the camera photographs the cloud droplets on the particle capture platform.
[0052] The image transmitter is used to transmit the cloud droplet images taken by the camera. The image transmitter is a wireless transmitter that transmits images. It modulates the image signal output by the camera into a radio frequency signal and transmits it to the ground receiver.
[0053] The cloud particle detector needs to detect in the air for dozens of minutes, so the water droplets on the transparent plate may be connected into pieces, making it impossible to distinguish the size of the cloud droplets. Therefore, a grease brush is designed to sweep away the water droplets on the transparent plate at a regular interval (for example, 10 seconds) and then brush another layer of grease.
[0054] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
[0055] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
