Problems solved by technology

[0011] The purpose of the present invention is to solve the problem in the prior art that "existing expressway rainfall early warning devices lack rainwater filtering structures. When it rains, a large amount of dust and impurities will float in the air, which will affect the accuracy of water storage; generally The early warning device adopts solar power generation or cable energization. When it r

Abstract

The invention discloses a highway rainfall early warning device with a rainwater filtering structure. The highway rainfall early warning device comprises an outer box, a supporting base and a mounting plate, wherein the supporting base is mounted on the inner wall of the outer box through bolts, a water collecting hopper is mounted on the inner side of the supporting base, a flow detector is mounted at the bottom part of the water collecting hopper through bolts, a metering box is installed at the bottom part of the flow detector through a bolt, the metering box is fixed into the outer box through a bolt, a connecting piece is installed on the inner side of the bottom part of the metering box, a limiting belt is connected to the bottom part of the connecting piece, a floating ball is installed at one end of the limiting belt, a storage battery is mounted on the inner side of the bottom part of the outer box through bolts and located on one side of the metering box, and a mounting plate is mounted on the inner wall of the outer box through bolts. A filter screen in the highway rainfall early warning device is composed of the gauze element and used for filtering falling rainwater, the filter screen filters out impurities, and the impurities are prevented from affecting the detection accuracy of the detection equipment.

Description

technical field [0001] The invention relates to the technical field of expressway rainfall early warning, in particular to an expressway rainfall early warning device with a rainwater filtering structure. Background technique [0002] Commonly used rain gauges are mainly mechanical rain gauges, one of which is a siphon rain gauge and the other is a tipping bucket rain gauge. In addition, there are a small number of radar rain gauges, optical rain gauges and pressure rain gauges. In actual use, siphon rain gauges and tipping bucket rain gauges are the majority. Among them, the siphon rain gauge counts the rainfall by measuring the height change of the float in the float chamber and the number of siphons, while the tipping bucket rain gauge realizes the rainfall statistics by recording the preset value of the tipping bucket and the number of times of flipping the tipping bucket. The purpose of measuring rain is to let drivers know the current rain and drive carefully. [00...
