Abstract

The invention discloses health detection equipment and method for a hectometer-level water diversion vertical shaft of a large-sized hydropower station. The equipment comprises an unmanned airship, adata acquisition device and a winch, wherein the data acquisition device is suspended below the unmanned airship through multiple nylon ropes; the bottom of the data acquisition device is connected with the winch; the data acquisition device is of a 4-layer structure, and comprises a shock absorption spring arranged on the top layer, a laser scanner, a pressure altitude sensor and an inert measurement device which are arranged on the second layer, a lighting device and a camera which are arranged on the third layer, and a control device arranged on the bottom layer; a defective position and adefect shape of the inner wall of the water diversion vertical shaft are obtained by processing various acquired data. The health detection equipment breaks through the problems in implementation of manual detection and high detection difficulty for the water diversion vertical shaft of the large-sized hydropower station, fills the international blank of informatization detection of a hectometer-level vertical shaft section, and solves the technical problems on determination of the defective position and measurement of the defect shape of the inner wall of the water diversion vertical shaft section.

Description

technical field [0001] The invention relates to the technical field of shaft health detection, in particular to a health detection equipment and method for a 100-meter-level water diversion shaft of a large hydropower station. Background technique [0002] During the construction of hydroelectric power stations, the upper reaches of the river or mountainous rivers with steep slopes often introduce the water in the reservoir into the water intake channel, and install a water turbine at the bottom of the water intake channel to use the high-speed flow of water to drive the generator set to work. In the process of continuous erosion by the water flow, there is a risk of concrete erosion on the inner wall of the water diversion channel, which may cause abnormal downtime for maintenance, or damage to the turbine and flow channel of the unit and endanger the operation of the entire water diversion power generation system, resulting in immeasurable consequences. The safe and stable...
