Problems solved by technology

[0005] (1) The existing scheme is suitable for open deep grooves on the ground. For the closed field structure on the top of the surge shaft of the hydropower station, the fixed pulley block cannot be installed on site for inspection
[0006] (2) The fixed pulley block cannot be moved, and the inspection area is limited
[0007] (3) The gimbal where the lighting and camera devices are located is stabilized by counterweights. During the lowering process, two people are required to tighten the counterweights and lower them gradually, which is laborious.
[0008] (4) The transmission of control signals and data signals is completed by cables, and the fixed pulley block is equipped with a motor, which requires more electrical equipment and is dangerous for low-voltage electricity

Embodiment

[0039] Assemble the detachable and assembled mobile hanger on the side of the surge shaft, and use the boom to send the imaging pan-tilt into the side of the surge well of the hydropower station into the manhole; the motor drives the lifting rope to move the three-axis stabilizing pan-tilt from the surge well Lower the side entrance to the target position to be inspected, then remotely control the pan / tilt and camera, select the horizontal position, pitch angle, magnification and fill light intensity when shooting images, and capture video or photos. Inspection and detection are carried out through high-definition image transmission, and the system is used to collect and store characteristic area information to grasp the internal structure of the surge shaft of Songtanpu Hydropower Station.

Abstract

The present invention proposes an imaging inspection device for the internal structure of a surge tank of a hydropower station. The inspection device includes a control system, a mobile hanger, and an imaging platform suspended at the boom of the mobile hanger by a sling; the boom extends obliquely. out or extend out horizontally; the imaging platform is wirelessly connected with the control system to receive control instructions and return the shooting image, the imaging platform includes a platform and a camera placed below the platform; the camera attitude of the platform is The control system is used to adjust the imaging direction; the control system is also equipped with an image transmission module to upload and shoot images to external equipment; the invention can conveniently perform imaging inspection on the internal structure of the surge well of the hydropower station.

Description

technical field [0001] The invention relates to the technical field of hydropower station maintenance, in particular to an imaging inspection device for the internal structure of a surge well of a hydropower station. Background technique [0002] When the diversion system of diversion-type hydropower stations has a long total length, a surge well is usually installed at the junction of the diversion tunnel and the pressure pipe. The surge well plays a role in reducing the water hammer pressure when the unit suddenly sheds the load and closes the guide vane during operation. Preventing water hammer effect from damaging hydroelectric power generation equipment is an important hydraulic structure of a diversion hydropower station, and it needs to be inspected regularly. The surge shaft of Songtanpu Hydropower Station has a diameter of 15m, a bottom elevation of 47.00m, a top elevation of 75.00m, and a height of 28m. It is lined with reinforced concrete with a thickness of 60cm....
