Description

Technical Field

[0001] The utility model belongs to the field of current meter fixing brackets, in particular to a positioning and fixing device for a hydrological survey current meter. Background Art

[0002] Remote hydrological flow measurement equipment is an instrument used to monitor hydrological data such as water flow, flow rate, water level and water quality. This type of equipment is usually used in the management and research of water bodies such as rivers, lakes and reservoirs, helping with water resource management, flood warning and environmental monitoring.

[0003] Existing flow meter positioning and fixing devices often use an integrated support rod to fix the flow meter. However, the integrated rod structure requires high labor costs during installation and use, and the installation height of the flow meter varies depending on the terrain. The edge of the integrated support rod needs to be adjusted accordingly according to the changes in the terrain.

[0004] Therefore, in order to address the problem that the above-mentioned existing flow meter positioning and fixing devices are often integrated structures, the height of the flow meter installed thereon is relatively fixed, and it is difficult to flexibly adjust according to the needs of workers for maintenance or use, a hydrological survey flow meter positioning and fixing device is developed. By adding an electric lifting structure, a limiting auxiliary structure and a photovoltaic power generation structure to the flow meter positioning and fixing device, the existing flow meter fixing bracket can be used to adjust the height of the flow meter during installation or use according to the needs of workers, so as to facilitate workers to maintain or use it. Utility Model Content
