Depth detection device for water conservancy and hydropower and application method thereof

Abstract

The invention discloses a depth detection device for water conservancy and hydropower and an application method thereof. The device comprises a detector body; a protective shell is arranged on the detector body; the detector body is connected with a balancing device and a detection probe through detection wires; the detection probe is arranged below the balancing device; the balancing device is fixed to the detection probe through a connecting block connecting column; and floating devices are arranged at the positions, located at the bottom end of the detection probe and close to the detectorbody, of the two ends of each detection wire. According to the depth detection device for water conservancy and hydropower and the application method thereof, rainwater entering the detector body canbe reduced, and the influence of breaking of the detector body on the application also can be avoided; whether the detection probe reaches the bottom or not can be known by judging whether the balancing device is inclined or not, data can be corrected, and the measurement accuracy is improved; through the floating devices, the return speed of the detection probe can be increased, the take-up strength of detection personnel can be reduced, and convenience is achieved.

Description

technical field [0001] The invention relates to the field of water level detection devices, in particular to a depth detection device for water conservancy and hydropower and a use method thereof. Background technique [0002] Bathymetry is the basic method of underwater topographic survey. It is to determine the plane position of each point on the bottom of the water and its depth below the water surface. It is the basic means of hydrographic survey and submarine topographic survey. The instantaneous depth under the water surface measured by the echo sounder, multi-beam echo sounder system and seabed geomorphology detector, etc., can be reduced to the depth calculated from the depth datum after being corrected by the echo sounder and the water level. However, there are certain disadvantages in the existing water depth detection device and method. Firstly, when the detection device detects, the force of pulling back the connecting wire from the bottom of the water is relativ...

AI Technical Summary

Problems solved by technology

However, there are certain disadvantages in the existing water depth detection device and method. Firstly, when the detection device detects, the force of pulling back the connecting wire from the bottom of the water is relatively large, and the requirements for the connection strength of the wire are relatively high. As a result, the safety data is inaccurate, the detector body is easily eroded by rainwater, and there is no protective device. Therefore, we propose a depth detection device for water conservancy and hydropower and its use method
