Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Fig. 1 shows the structure of the weighing type rain and snow measuring device provided by the embodiment of the present invention, and only the parts related to the embodiment of the present invention are shown for convenience of description.
As shown in fig. 1, the weighing type rain and snow measuring device provided by the present embodiment comprises a base 1, a mounting plate 2 is arranged on the top of the base 1, the top of the mounting plate 2 is connected with a shell 4 through a connecting piece 3, a weighing device 5 is arranged at the bottom in the shell 4, the top of the weighing device 5 is provided with a tray 6, a collecting barrel 7 is arranged on the tray 6, the top of the shell 4 is provided with a collecting channel 8 which is opposite to the collecting barrel 7, the collecting channel 8 is of a double-layer structure, a circle of air nozzles 9 are arranged on the inner layer near the top, a section of collecting port 10 is arranged inwards on the top of the collecting channel 8, the outer wall of the collecting opening 10 is provided with a circle of necking inclined plane 11 at the position opposite to the air tap 9, the outer wall of the shell 4 is fixed with a mounting box 12, a fan 13 and an electric heating wire 14 are arranged in the installation box 12, and the installation box 12 is communicated to the bottom of a cavity formed by the inner-layer structure and the outer-layer structure of the collection channel 8 through a connecting pipe 15.
Wherein, casing 4 periphery is equipped with support frame 16, support frame 16 top is equipped with the solid fixed ring 17 of round, gu fixed ring 17 evenly is provided with a plurality of windbreak boards 18 downwards towards collection channel 8 slant. The windproof plate is arranged to play a role in keeping out the wind, and the influence of wind on the windproof plate in the collecting process is prevented from causing inaccurate measuring results.
In this embodiment, a rain and snow sensor 19 is mounted on the top of the fixing ring 17. When the low-temperature weather comes temporarily, the rain and snow sensor can detect the sleet or snowflake, thereby starting the fan and the heating wire in the installation box.
