Description

Technical Field

[0001] This utility model relates to the field of ultrasonic wind speed measurement technology, and specifically to an ultrasonic wind speed measuring device. Background Technology

[0002] Measuring wind speed and direction provides important meteorological information and is of great significance for weather forecasting, aviation and maritime safety, air quality monitoring, agricultural and forestry management, construction engineering and urban planning. Wind speed and direction instruments are usually installed at observation points to monitor and obtain relevant data.

[0003] The prior art discloses (publication number: CN221960176U) an ultrasonic anemometer, including an instrument body and a detection platform. The detection platform is located at the top of the instrument body, and an ultrasonic detector is installed on the upper part of the detection platform. A baffle is provided on the upper part of the detection platform, and at least two fixing rods are fixed between the baffle and the detection platform. A humidity sensor and a buzzer are connected to the lower end of the baffle. An installation cavity is opened inside the baffle, and a rotating motor is fixed in the installation cavity. This prior art, by setting up a buzzer, when a bird stands at any position above the detection platform, the overall weight of the detection platform increases, so the proximity switch is activated, thereby energizing the buzzer. The sound emitted by the buzzer can drive away the birds, effectively preventing birds from interfering with the normal detection of wind speed and direction by the anemometer, which helps to ensure the accuracy of the wind speed and direction detection results.

[0004] However, the existing technology has the following drawbacks: when birds land instantly above the telescopic cover, the telescopic cover above the ultrasonic anemometer descends, causing a change in the space above the ultrasonic anemometer, which interferes with the ultrasonic waves emitted by the ultrasonic anemometer, thus affecting the accurate data of the ultrasonic anemometer test. To address this issue, we propose an ultrasonic anemometer measurement device to solve the above problems. Utility Model Content

[0005] The present invention aims to provide an ultrasonic anemometer to solve the problem that the ultrasonic waves emitted by the existing anemometer are interfered with when birds land overhead.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic wind speed measuring device, comprising a measuring body for measuring wind speed, including a bird-proof component and a fixing component. The bird-proof component includes a mounting shell, a trigger spring, a trigger button, and several sound-emitting components. The mounting shell is located at the upper end of the measuring body, and a cavity is opened inside the mounting shell. A support column is provided in the cavity. The trigger spring is located on the outer wall of the support column, and the trigger button is located at the upper end of the trigger spring. Several sound-emitting components are arranged in a ring on the inner wall of the cavity. Each set of sound-emitting components includes a mounting base, a connecting rod, a connecting spring, and two steel balls. The mounting base is located on the lower wall of the cavity, the connecting rod is located inside the mounting base, and the trigger button can contact the connecting rod. The connecting spring is located on the upper wall of the mounting cavity, one steel ball is located at the lower end of the connecting spring, and the other steel ball is located at the end of the connecting rod away from the trigger button, and the steel ball at the upper end of the connecting rod can contact the steel ball at the lower end of the connecting spring.

[0007] The beneficial effects of this solution are as follows: the trigger spring is used to reset the trigger button, and the trigger button is used to detect whether a bird has landed above the measuring body. When a bird lands above the trigger button, it presses down on the trigger button under its own weight, causing the trigger button to contact the connecting rod. This causes the steel ball connected to the other end of the connecting rod to move upward, and then collide with the steel ball at the lower end of the connecting spring to make a sound, thus startling the bird. During this process, the space above the measuring body does not change, and it does not affect the normal operation of the measuring body, thereby increasing the accuracy of the measuring data.

[0008] Preferably, as an improvement, a return spring is provided between each connecting rod and the cavity.

[0009] The beneficial effects are as follows: the return spring is used to reset the connecting rod, and at the same time, the connecting rod impacts the inner wall of the cavity, thereby producing a secondary sound, which in turn frightens away the birds.

[0010] Preferably, as an improvement, a rain cover is provided on the upper part of the trigger button.

[0011] The beneficial effects are: the rain cover is used to shield the bird-proof component, preventing rainwater from entering the cavity. At the same time, the rain cover can also increase the contact area of ​​the trigger button, thereby triggering the sound element more quickly and accurately, thus driving away landing birds.

[0012] Preferably, as an improvement, the lower end of the detection body is provided with a mounting post, the lower end of the mounting post is provided with a support plate, the mounting post has an annularly formed mounting cavity, a fixing component is provided in the mounting cavity, the fixing component includes a rotating ring, an adjusting block, a mounting ring, a spring and several ground nails, the mounting ring is provided in the mounting cavity, the support plate has an annularly formed several through slots, the several ground nails are annularly provided at the lower end of the mounting ring, and each ground nail can pass through the through slot, the spring is provided between the support plate and the mounting ring, the rotating ring is provided at the upper end of the mounting ring, a limiting groove is provided on the outer wall of the mounting post, the adjusting block is provided on the outer wall of the rotating ring and is located in the limiting groove, and a buffer component is provided between the mounting post and the mounting cavity.

[0013] The beneficial effects are as follows: The mounting column has an installation cavity, and the fixing components inside the cavity make the entire installation process simpler. By setting several ground nails at the lower end of the mounting ring, the ground nails can penetrate the through groove of the support plate and insert into the ground, ensuring that the anemometer can be firmly fixed in different terrains and preventing the detector from tipping over due to wind or external impact. The user only needs to step on the adjusting block to push the mounting ring into the ground, thereby fixing the ultrasonic anemometer. Then, by rotating the rotating ring, the adjusting block is pushed into the limiting groove, which fixes the adjusting block and prevents the mounting ring from moving. The spring is used to reset the mounting ring and also allows the adjusting block to abut against the inner wall of the limiting groove, thereby increasing the support effect of the ground nails and improving the stability of the ultrasonic anemometer.

[0014] Preferably, as an improvement, the upper end of the rotating ring is provided with a sealing cover, which is used to cover the limiting groove.

[0015] The beneficial effects are as follows: When the ground nail is inserted into the ground, in order to prevent debris from entering the installation cavity, a sealing cover is set at the upper end of the rotating ring to block the limiting groove. While preventing debris from entering the installation cavity, it can also reduce the sealing of the installation column in windy weather and improve the stability of the ultrasonic anemometer.

[0016] Preferably, as an improvement, the buffer assembly includes a sealing ring and several vent holes. The sealing ring is located at the upper end of the sealing cover and abuts against the inner wall of the mounting cavity. The several vent holes are evenly and continuously opened at the upper end of the mounting post and are connected to the mounting cavity.

[0017] The beneficial effects are as follows: When the ultrasonic anemometer is retrieved, the user needs to push the adjusting block out of the limiting groove, so that the mounting ring is reset under the action of the spring. However, the spring reset will generate a large impact force, which will be transmitted to the detection body through the mounting post, thereby damaging the detection body. In this solution, a sealing ring is set at the upper end of the sealing cover, so that a cavity is formed between the mounting cavity and the sealing ring. Then, the cavity is slowly vented through the exhaust hole, thereby reducing the impact force generated when the spring resets and increasing the service life of the detection body.

[0018] Preferably, as an improvement, each through groove is provided with a rubber pad, the rubber pad has a cross-shaped opening in the middle, and each ground nail can pass through the rubber pad.

[0019] The beneficial effects are: when the ground nail is retracted into the installation cavity, the cross-shaped opening in the middle of the rubber pad can scrape off the soil attached to the outer wall of the ground nail, thereby reducing the weight of the ultrasonic anemometer after recovery and making it easier to transport.

[0027] A mounting column 13 is fixedly installed at the lower end of the detection body 1. A support plate 14 is fixedly installed at the lower end of the mounting column 13. Several anti-slip teeth are evenly fixedly installed at the lower end of the support plate 14. The anti-slip teeth are used to increase the friction between the support plate 14 and the ground and prevent the support plate 14 from rotating relative to the ground. Figure 3 The mounting post 13 shown has a ring-shaped mounting cavity 15 inside. A fixing assembly is located within the mounting cavity 15. The fixing assembly includes a rotating ring 16, an adjusting block 17, a mounting ring 18, a spring 19, and several ground nails 20. The mounting ring 18 is slidably mounted within the mounting cavity 15. A number of through slots 21 are ring-shaped through the lower end of the support plate 14. Several ground nails 20 are ring-shaped and fixedly mounted on the lower end of the mounting ring 18, and each ground nail 20 can pass through the corresponding through slot 21. A rubber pad is fixedly installed on the inner wall of each through slot 21. A cross-shaped opening is formed in the center of the rubber pad, and each ground nail 20 can pass through the rubber pad. The cross-shaped opening in the center of the rubber pad can scrape off the ground nail. The soil attached to the outer wall of the 20 reduces the weight of the recovered ultrasonic anemometer, making it easier to transport. The spring 19 is fixedly installed between the support plate 14 and the mounting ring 18. The upper end of the mounting ring 18 has a concave groove. The lower end of the rotating ring 16 is fixedly installed with a T-shaped slider.

Each vent hole 25 is provided with a filter screen at the end exposed on the mounting post 13. The filter screen is used to prevent debris from entering the mounting cavity 15 through the vent hole 25, so as to avoid clogging the vent hole 25 and affecting the normal reset of the spring 19.

[0029] The specific implementation process is as follows:

[0030] When a user needs to fix the ultrasonic anemometer to the ground, first determine the placement position of the ultrasonic anemometer, place the support plate 14 on the ground, and then simply step on the adjusting block 17 to compress the spring 19. Simultaneously, the mounting ring 18 pushes the ground nail 20 into the ground, thus fixing the ultrasonic anemometer. Then, by rotating the rotating ring 16, the adjusting block 17 is pushed into the corner of the limiting groove 22, which fixes the adjusting block 17, preventing the mounting ring 18 from moving. Furthermore, during the descent of the mounting ring 18, the sealing cover 23 will block the limiting groove 22, thereby... To prevent the limiting groove 22 from increasing the wind resistance of the ultrasonic anemometer in windy weather, which could cause the ultrasonic anemometer to shake or even tip over, when unlocking the ultrasonic anemometer, simply move the adjusting block 17 out of the corner of the limiting groove 22, and the mounting ring 18 will reset under the action of the spring 19, causing the ground nail 20 to retract into the mounting cavity 15. At the same time, since the sealing ring 24 is set at the upper end of the sealing cover 23, a cavity 3 is formed between the mounting cavity 15 and the sealing ring 24. The cavity 3 is then slowly vented through the exhaust hole 25, thereby reducing the impact force generated when the spring 19 resets, which increases the service life of the detection body 1.

[0031] When a bird lands on the top of the rain cover 12, its own weight causes it to press down the trigger button 5, making the trigger button 5 contact the connecting rod 8. This causes the steel ball 10 connected to the other end of the connecting rod 8 to move upward, and then collide with the steel ball 10 at the lower end of the connecting spring 9 to make a sound, thus startling the bird. During this process, the space at the top of the measuring body does not change, and it does not affect the normal operation of the measuring body, thus increasing the accuracy of the measuring data.
