Problems solved by technology

In the case of high water velocity, the physical exertion of divers is fast and the movement is inconvenient, which is not conducive to the development of repair work
Due to the presence of silt, when divers remove the silt on the surface, the surrounding water immediately becomes turbid and the visibility is extremely low, making it difficult for divers to carry out follow-up operations
Deeper dam operations currently use more underwater unmanned submersibles (ROV). The dam surface is observed through the observation equipment carried, and cracks cannot be repaired. At the same time, due to the reinstallation of the flow field and the The presence of silt further limits the ROV's ability to repair cracks

Abstract

The invention relates to a remote-control type face dam crack repair manned device and operation method, comprising a carrier frame, a buoyancy block is installed above the carrier frame, and vertical propellers are respectively installed at four upper corners of the carrier frame and a horizontal thruster, a manned cabin is welded in the middle of the carrier frame, and an adsorption skirt is installed on the bottom of the manned cabin through a sealing device; a hydraulic source, a seawater pump, High-pressure oxygen cylinders, junction boxes and control cabins, high-pressure air cylinders are installed horizontally at the front end of the carrier frame outside the manned cabin, and manipulators are installed at intervals on the carrier frame opposite to the high-pressure oxygen cylinders. How free is the installation of the manipulators? High-speed grinding tools; a gas concentration control device is installed inside the manned cabin, and a dam surface crack repair system is installed inside the adsorption skirt, which works reliably.

Description

technical field [0001] The invention relates to the technical field of deep-water dam maintenance equipment for water conservancy and hydropower, in particular to a remote-controlled manned device for repairing cracks in face-face dams and an operating method. Background technique [0002] At present, there are nearly 140 high dams over 100 meters in China, and the number of ultra-high dams over 200 meters ranks first in the world. The highest dam body is 300 meters high, of which face-face dams account for a considerable proportion. As the age of the dam increases, some defects appear in the dam body. In the initial stage of defects, cracks in the dam body are the main ones. If the cracks are not dealt with in time, they will develop into more serious defects such as panel shedding. Not only It has an important impact on the safety of the dam body, and also has a great impact on the manpower, financial and material resources consumed by subsequent dam body restoration. The...
