The utility model discloses can demonstrate wind direction and wind speed for student's image directly perceivedly.
Description
Technical Field
The utility model relates to a demonstration ware especially relates to a wind direction wind speed demonstration ware.
Background
In the textbook 'science', the experiments related to the wind direction and the wind speed are usually performed in a classroom, students can only listen to the explanation of teachers and cannot visually and intuitively observe the explanation, and even if the experiments are performed on a playground, the experiments are influenced by buildings and the effect is not obvious.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve how let the student produce wind with little fan circular telegram in the classroom to change into the straight wind with the spiral wind, and do not receive the influence of environmental factor, and through digital display's anemoscope and wind vane, let the technical problem of student visual observation wind direction wind speed.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the wind direction and wind speed demonstrator comprises a base, a rotating disk, a fan bracket, a sliding rheostat, a power switch, a fan, a power supply, a compass, a camera bracket, a miniature camera and a USB plug, wherein the rotating disk is placed in the middle position above the base; a compass is arranged on the rotating disc; the camera support is movably clamped on the rotating disk, a miniature camera is mounted on the camera support and connected with a USB plug through a wire, and the USB plug is connected with a USB interface on the display device.
And the middle position of the rotating disc is aligned with the air outlet surface of the fan, and a wind vane is arranged.
And an anemoscope is arranged at the middle position of the rotating disc and aligned to the air outlet surface of the fan.
The power supply is a common No. 5 battery.
The power supply is a 5V power adapter.
The beneficial effect of adopting above-mentioned technical scheme is:
the utility model discloses can demonstrate wind direction and wind speed visually in image: the wind direction refers to the direction of wind blowing, and the position of a wind source can be adjusted by utilizing the rotating disc so as to adjust the wind direction; the wind speed refers to the distance of the wind per second, the current wind power can be visually displayed by using a digital display anemometer, and the rotating speed of a fan can be changed by using a sliding rheostat to measure different wind speeds.
Drawings
