Snorkeling-type emergency hydrographic measurement device

Abstract

The invention relates to a snorkeling-type emergency hydrographic measurement device and solves the problems of high difficulty and cost in comprehensive coverage of hydrological current measurement in small and medium-sized rivers in the Jiangnan region, as well as high operation difficulty and high setting requirements of existing small manual current measurement devices. The device comprises asteel wire stretching across a river. A walking frame is slidably arranged on the steel wire; a floating ball is hung under the walking frame through a suspension cable; the floating ball floats on the water; the bottom surface of the floating ball is provided with a Doppler probe; the top surface of the floating ball is provided with a reflection prism; and the two sides of the floating ball facing the riverbanks are respectively provided with a traction rope connected to the corresponding riverbank. The device adopts the floating ball as the current measuring carrier, thereby greatly reducing tension on a hydrological cableway; the cableway can adopt a lower-strength steel wire material, thereby reducing self weight of the cableway and reducing sag of the cableway, and furthermore, reducing difficulty in manual hydrographic measurement and reducing hydrographic measurement cost; and the device can realize more comprehensive hydrographic information measurement at the same hydrographic survey cost.

Description

technical field [0001] The invention belongs to the field of hydrological measurement, and relates to a hydrological measurement device, in particular to a snorkeling emergency hydrological measurement device. Background technique [0002] The hydrological department needs to monitor the hydrological information of the river all year round, provide hydrological data for various construction plans of the country, and also provide data support for local flood control and drought prevention work. In order to grasp the key hydrological information of a region, the hydrological department will select fixed river channel observation points to build a hydrological base station. The hydrological base station is a fixed facility set up for a long time. Columns are set up on both sides of the river. The device travels along the hydrographic cableway while taking measurements. The traditional hydrological cableway is a steel cableway. The flow measurement generally uses a lead fish su...
