Raindrop falling inclination angle measuring method and device

Abstract

The invention belongs to the technical field of detection and relates to a raindrop falling inclination angle measuring method and a raindrop falling inclination angle measuring device so as to measure the raindrop falling inclination angle. The raindrop falling inclination angle is measured by a horizontal baffle plate and a vertical rainwater sensing array arranged in a front open casing, in particularly, the horizontal baffle plate is arranged horizontally, the length L2 of the horizontal baffle plate is adjustable, and the horizontal baffle plate is used for controlling the height of the raindrops falling into the vertical raindrop sensing array; the vertical raindrop sensing array consists of raindrop sensing units arranged vertically, the number of the raindrop sensing units is N, and the number of the raindrop sensing unit for outputting 'non-raindrop' information is set as N-M; according to the geometrical relationship, the following equations are established: the equations are as shown in the description; and according to the above equations, the inclination angle of the raindrop falling trace and the vertical line can be calculated (the formula is as shown in the description), wherein the length of each raindrop sensing unit is L. The raindrop falling inclination angle measuring method and the raindrop falling inclination angle measuring device are mainly applied to raindrop falling inclination angle measuring occasions.

Description

technical field [0001] The invention belongs to the technical field of detection, in particular to a method and device for measuring the inclination angle of falling raindrops. Background technique [0002] According to statistics, in the summer in the south of the Yangtze River in my country, more than 40% of rainy days are accompanied by a wind speed of not less than level 4 in the process of falling rain, and such wind speed will make the raindrops not perpendicular to the ground (assuming the ground is parallel to the ground). The horizontal plane is parallel) falls, but falls at a certain inclination angle θ with the ground; the size of the inclination angle θ is related to the quality of the raindrops and the wind speed, when the inclination angle reaches a certain value, the raindrops will fall into the residents’ homes from the open windows , causing water damage to wooden floors or other items in the home, or causing wet clothes to be dried. For this reason, the pres...

[0002]According to statistics, in the summer in the south of the Yangtze River in my country, more than 40% of the rainy days are accompanied by a wind speed of not less than grade 4 in the process of falling rainwater, while Such a wind speed will cause the raindrops to fall not perpendicular to the ground (assuming that the ground is parallel to the horizontal plane), but fall at a certain inclination angle θ with the ground; the size of the inclination angle θ is related to the quality of the raindrops and the wind speed. When the inclination angle reaches At a certain value, raindrops will fall into the residents' homes from the open windows, causing water damage to the wooden floor or other items in the home, or causing the clothes to be dried to be wet
