Automatically washable gulley flow measuring device

Abstract

The invention discloses an automatically washable gulley flow measuring device, comprising a flow guide box, a rectification assembly, a rainwater grate, a combined metering weir plate and a water level measurement assembly. A water inlet is set on the diversion box. The rectification assembly connected with the water inlet is set in the flow guide box. The rainwater grate is set on the flow guidebox and covers the water inlet on the flow guide box. The combined metering weir plate is set on a side face of the flow guide box. Two effluent weirs are set at upper and lower parts of the combinedmetering weir plate. An inclined base plate is set at the bottom of the flow guide box. A high end of the inclined base plate is located at one side of the flow guide box, and the combined metering weir plate is set at the side of the flow guide box. The water level measurement assembly is set at the bottom in the flow guide box and measures a water level in the flow guide box to obtain weir headwater for computing of flow. According to the device, gulley flow can be effectively measured. The device can be automatically washed. A water outlet is prevented from being blocked by deposited silt. The device is incomplex in structure and low in cost and is convenient for use. The gulley traffic can be accurately measured.

Description

Technical field [0001] The invention relates to the field of rainwater flow measurement, in particular to a rainwater flow measurement device capable of automatically washing which is suitable for road rainwater flow measurement. Background technique [0002] In the construction of a sponge city, it is necessary to measure the amount of rainwater that flows to the gully. The composition of rainwater is complicated. The mixture of sediment and water will produce sediment deposition, and the unevenness of rainfall is affected and restricted by factors such as rainwater. The measurement of port flow is difficult, and there is no ideal flow measurement device. Summary of the invention [0003] Based on the problems in the prior art, the object of the present invention is to provide a rainwater outlet rainwater flow measuring device, which can conveniently and accurately measure the rainwater flow of the rainwater outlet, and can perform automatic flushing to avoid blockage. [0004] Th...
