Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] The method used in the present invention is a water body flowing silk thread video display technology method. The device mainly consists of three parts: a fully sealed video display probe, a wire frame and a probe frame. The video display probe is the main device, which is composed of a camera 9, a video optical transceiver 10, a transparent shell and a waterproof filling glue, see figure 1 , There is a cable outlet and two hanging lugs on the shell 2, the hanging lugs are used to install the probe on the probe frame, and can shake freely, and are connected with the shell through a waterproof threaded joint. The lens surface of the camera is tightly attached to the transparent bottom cover, fixed and waterproof with epoxy resin glue filled inside. The wire rack consists of a fixing ring, steel bars and wires. The fixing ring is used to fix the thread holder...

The invention discloses a measuring device and method for measuring the flowing speed and the flowing direction of a high-pressure water body. The measuring device comprises a probe frame, a video display probe structure and a silk thread frame, wherein the video display probe structure is arranged on the probe frame; the silk thread frame is arranged at the front end of the video display probe structure; the video display probe structure comprises a drum body which is internally provided with a camera and a video optical transceiver; the silk thread frame comprises a fixed rod which is provided with a silk thread rod; and the tail end of the silk thread rod is positioned at the front end of the camera and is connected with silk threads. Compared with the prior art, the measuring device comprises two main parts, namely the probe structure and the silk thread frame, the silk threads arranged on the silk thread frame and capable of floating and swinging freely can present the flowing direction and the flowing speed of the water body in an omni-directional manner and the presented flowing direction and flowing speed of the water body can be recorded and visualized by the camera of the probe part; therefore the measuring device can be used for realizing the omni-directional flowing measurement of the water body and is simple and ingenious in structure.
Description
technical field [0001] The invention relates to technical fields such as water conservancy engineering, hydrology and water resources, marine engineering, etc., especially the measurement of the flow direction and speed of water bodies in pressurized tunnel engineering in the field of water conservancy engineering. Background technique [0002] The invention is mainly used to measure the flow velocity and flow direction of the water body in the pressurized tunnel, and can also be used to measure the flow velocity and flow direction of the deep part of the surface water body (that is, high water pressure). The purpose of measuring the flow velocity and flow direction of the water body in the pressurized tunnel is to determine the leaking part of the pressurized tunnel. When there is no inflow and outflow of water in the tunnel as a whole, that is, the water body is in a static state, the part where the flow velocity in the tunnel is measured by this invention is The leaking p...
