Embodiment Construction
[0037] It can be seen from the background technology that it is difficult to measure the rainfall inclination angle in the process of wind and rain.
[0038] In order to determine the rainfall inclination at a certain moment, the embodiment of the present invention provides a rain inclination measuring device. The rainwater receiving device is equipped with rainwater receiving ports with equal areas, and the directions of the planes where the rainwater receiving ports are located are different, so that it can receive rainwater from different directions. At the same time, the rainwater receiving chamber connected with the rainwater receiving port can collect the amount of rainwater flowing into it. When measuring the rainfall inclination angle, place it at the measurement position, use the rainwater receiving port to receive rainfall, and then obtain the rainwater with the largest amount of rainwater The rainwater receiving port corresponding to the receiving chamber determines ...

The invention discloses a rainfall dip angle measuring device which comprises a rain water receiving device and a rain water measuring device, wherein at least two rain water receiving openings are formed in the rain water receiving device, the rain water receiving openings are in the same size, the range of the included angles between the planes where various rain water receiving openings are anda vertical plane is -90 degrees to 90 degrees, and the included angles between the planes where various rain water receiving openings are and the vertical plane are all different; and rain water measuring device is provided with a rain water containing cavities, the number of the rain water containing cavities is equal to the number of rain water receiving openings, and the various rain water containing cavities communicate to the rain water receiving openings corresponding to the rain water containing cavities to facilitate that the rain water collected through the rain water receiving openings flows into the corresponding rain water containing cavities. Through measurement and comparison of the rain water volume collected by the rain water receiving openings with different opening directions in a certain time period, the rainfall dip angle at the time is determined, the principle is clear, the operation is simple, the rainfall dip angle measuring device can be applied to the measurement of the rainfall dip angle in a rainfall process under the situation that a wind field is instable, and rainfall dip angle data can be conveniently and quickly acquired without complex calculationneeded.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of rainfall runoff simulation, and in particular to a device for measuring rainfall inclination angle. Background technique [0002] The rainfall inclination is caused by the horizontal velocity of the raindrops affected by the wind during the falling process. The rainfall inclination angle has a significant impact on the amount of rainfall received by the receiving surface, the dynamic interaction characteristics of raindrops and the rainfall receiving surface, and the relationship between rainfall and runoff in urban watersheds. influencing factors. [0003] Since the wind speed in a rainfall is not constant, the inclination angle of the raindrops will be complex and changeable, and the raindrops will undergo deformation, change direction, fragmentation, sputtering and other processes after contacting the solid interface. Therefore, it is very difficult to directly measure the rainf...
