Description

Technical Field

[0001] The utility model relates to the technical field of ocean droplet measurement, in particular to an ocean droplet flux meter. Background Art

[0002] Early methods of observing ocean droplets mainly used reagent paper to observe seawater droplets produced by breaking waves, but this requires a lot of manual work, is relatively inefficient, and can only measure large seawater droplets. In recent years, optical-based ocean droplet measurements have been widely used. Optical-based ocean droplet measurements can be specifically divided into measurement technology based on optical scattering and measurement technology based on optical imaging. Measurement technology based on optical scattering can measure the size of particles, but it cannot obtain the specific shape and speed information of the particles, and the measured particle size range is limited. Optical imaging measurement technology can not only measure the size of particles, but also record the image of particles. According to the image of particles, the shape information of particles can be obtained, but the existing optical imaging technology cannot obtain the speed information of ocean droplets.

[0023] The technical solution of the utility model is described in detail below in conjunction with the embodiments and drawings.

[0024] The utility model provides an ocean droplet flux meter, such as Figure 1 As shown, it includes: a laser protection cover 1, a collimating laser 2, a connecting arm 3, a window mirror 4, a window mirror protection cover 5, an optical module 6, a main body casing 7, a photoelectric conversion circuit board 8 and a power supply 9.

[0025] Specifically, the laser protection cover 1 is arranged at one end of the ocean droplet flux meter equipment, and is a protection cover for the collimated laser, ensuring that the laser is sealed and not corroded by external rain and sea fog.

[0026] The collimated laser 2 provides a collimated laser beam, which is irradiated to the photoelectric conversion circuit board 8 at the other end of the device through the sampling area.

[0027] The connecting arm 3 fixes the laser protection cover 1 to the main housing 7 to form a whole, which is convenient for the installation of the equipment. The connecting arm is hollow and a power line can be pre-buried to provide power for the collimating laser 2.

[0028] The window mirror 4 is a radiation-resistant and highly transparent sapphire lens, and is designed with two layers of window mirrors. The inner window mirror is fixed with glue and mainly plays a sealing role. The outer window mirror is fixed with a sealing ring to isolate the attachment of salt spray particles. The threaded connection method is convenient for replacement during later maintenance. The window mirror 4 mainly provides a sealing effect to prevent sea air from entering the equipment through the gap to corrode the circuit board. However, in the marine environment, it is easy for the window mirror to be covered with sea salt, which affects the light intensity and particle imaging, and needs to be disassembled and cleaned regularly. Due to the special measurement position of the equipment, professional personnel are required for installation and fixation. Therefore, each time the window mirror is cleaned, the equipment needs to be disassembled first, and then the window mirror is disassembled and soaked with alcohol. After wiping it clean, the window mirror is installed on the equipment, and the sealing must be ensured. Finally, the equipment is reinstalled to the observation position, which is inconvenient to operate and maintain and takes a long time each time. The utility model adds a layer of threaded window mirror sealing ring outside the sealed window mirror, so that the first layer of window mirror can be directly replaced when seawater splashes and sea salt covers it. Each time, just bring 2 sets of clean window mirror seals and replace them directly at the observation position. This ensures that the outer window mirror is covered with sea salt without affecting the sealing of the inner window mirror. It is convenient and quick.

[0029] The window mirror protective cover 5 provides a support for sealing the window mirror 4 .

[0030] The optical module 6: the shadow formed by the particle passing through the sampling area irradiated by the collimated laser 2 is shaped and projected onto the photoelectric conversion circuit board at the rear end through the optical module 6.

[0031] The main housing 7 is made of 304 stainless steel and painted with anti-corrosion paint. The exterior of the housing is used for fixed installation. The interior is sealed to facilitate storage of electronic components such as power supplies, circuit boards, signal processing boards, etc. required by the device.

[0032] The photoelectric conversion circuit board 8 receives the optical path signal of the collimated laser 2, and when a particle passes through the sampling area, causing the light intensity to change, the light intensity signal is converted into a voltage signal for recording and scanning the time and size of the particle passing. This process is a conventional technical means in this field and does not involve improvement of the method.

[0033] The power supply 9 provides different DC voltage modules for the collimating laser 2 and the photoelectric conversion circuit board 8 .

[0034] The utility model provides an ocean droplet flux meter, and the specific working principle is:

[0035] The power supply 9 supplies power to the photoelectric conversion circuit board 8 and the collimated laser 2. When a particle passes through the sampling area formed by the connecting arm 3, the collimated laser emitted by the collimated laser 2 is blocked, and the resulting shadow is projected onto the photoelectric conversion circuit board 8 through the optical module 6 to record the particle size and passing time.

[0036] The utility model studies a measuring device which can directly observe the size and speed of ocean spray particles and scan and image them.

[0037] Any content not described in detail in the present invention can be based on the conventional technical knowledge in the field.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the embodiments, a person skilled in the art should understand that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
