High-precision hydrological flood mark detection device

Abstract

The invention discloses a high-precision hydrological flood mark detection device. Racks are arranged on the inner walls of the left side and the right side of a barrel; clamping plates are arranged on the inner walls of the front side and the rear side of the barrel. Clamping grooves are formed in the front section and the rear section of a fixing plate, a floating block is fixed to the bottom ofthe fixing plate, and waterlines are marked on the floating block. The fixing plate is arranged in the barrel, and the clamping grooves are matched with the clamping plates. A double-head necking pipe in the left-right direction is fixed to the top of the fixing plate; a spring is installed in the double-head necking pipe; Insertion columns are installed at the left end and the right end of the double-end necking pipe respectively; clamping heads are fixed to the outer side ends of the insertion columns; clamping blocks are fixed to the inner side ends of the insertion columns. According to the device, the racks are used for fixing the position of the column floating block; flood marks are obtained by observing the waterlines on the floating block, the distance between every two adjacentteeth on the racks is very small, even if the rising height of the water level is small, the height can be recorded; the position of the floating block cannot descend once the position of the floatingblock is fixed, and the position of the floating block will not descend when the flood recede, and therefore, compared with the effects of previous two patents, The flood mark recording error of thedevice of the invention is greatly reduced.

Description

technical field [0001] The invention relates to a high-precision hydrological flood mark detection device, which belongs to the technical field of hydrological monitoring equipment. Background technique [0002] The hydrological department needs to monitor various hydrological information in the region all year round, providing hydrological data for various construction plans of the country, and playing an important role in the development planning around the river; the hydrological department monitors the more hydrological information according to the actual conditions. Good, the more complete the better, the more accurate the better; hydrological information includes but not limited to the flow, flow velocity, and water level information of the river in each season, the precipitation information of each region, and the flood water level information. Limited by funds, personnel, and monitoring technology, the hydrological department can only establish base stations for majo...

AI Technical Summary

Problems solved by technology

[0003] In the southern region, due to the influence of typhoons and other weather, there are occasional floods. The hydrological department needs to collect the flood peaks to provide data support for regional construction planning. For once-in-a-lifetime floods, especially for non-key hydrological monitoring areas such as mountainous areas and villages, it is impossible to collect data in real time; the traditional method of flood peak collection is to wait for the flood to recede to find flood marks, and determine the flood peak according to the flood marks. Influenced by objective conditions, the accuracy is poor; so it is necessary to provide a flood water mark monitoring device to solve the above technical problems

[0004] In the prior art, for example, a hydrological flood mark monitoring device with a patent application number of 201920330591.7, and a flood water mark monitoring device with a patent application number of 201921486814.5, although these devices can record the traces of flood peaks and keep them for a long time; but The floating ball of the flood peak trace recorded by it stays between two boards with a large distance, and the two adjacent boards form an interval. The flood peak trace recorded by the floating ball is also within this interval. The flood peak trace represented by the ball may be a certain value in this interval, but the floating ball will eventually fall to the bottom of this interval as the water level drops as the flood recedes, and when the staff collects data, they can only get data within this interval. Therefore, the data error is relatively large; for this reason, the inventor designed a high-precision hydrological flood mark monitoring device, which can record the traces of flood peaks and keep them for a long time, providing a certain reference for later flood mark monitoring
