Abstract

The invention discloses a device for gauging well freeze prevention during a low water level period of a reservoir in a cold area. The device comprises an electrical heating bar (1), buoys (2), external connection cables (3) and a power switch; the buoys (2) float in a gauging well; the electrical heating bar (1) is arranged at the buoys (2); and the external connection cables (3) are connected with the electrical heating bar (1) and the power switch. The invention also discloses a working method of the device. The problem that the gauging well, operating in winter, of the reservoir in the cold area is frozen is solved and the reliability of water level data is improved. A reliable guarantee is provided for scientific operation of the reservoir, a safety guarantee is provided for engineering construction, a reliable source is provided downstream water supply, and huge electricity benefits are created for a power generation enterprise.

Description

Technical field [0001] The invention belongs to the technical field of hydroelectric power generation and water conservancy hubs, and in particular relates to a device and a working method for preventing freezing of a water level well when a reservoir is low in a cold area. Background technique [0002] With the change of reservoir operation mode, each reservoir is facing the challenge of environmental change, especially the data collection of reservoir operating water level in cold areas in winter is gradually affected by the environment. The water level is one of the important factors in the calculation of reservoir operating data. It can be seen that the accuracy and timeliness of the reservoir water level is particularly important. In this way, it is more difficult for water level wells to prevent freezing in cold areas. Especially in the years of low water level, the more the water inlet hole of the water level well leaks, the more cold air enters, causing the water level w...
