Abstract:
The apparatus contains a boom (4), at the end of which there is a measuring device (5). The boom (4) is affixed to a multi-section clamp (3) with adjustable length, which is mounted on a sling (1) affixed to a bridge support (2). The boom (4) consists of a guide (18) mounted slidably and rotatably in a sleeve (19), with the option to stabilize a specific position of this guide (18) with respect to the sleeve (19). One guide (18) end is connected to the cover (6) of the measuring device (5). The sleeve (19) of the boom (4) is affixed to the lower part (10) of the clamp (3).
Abstract:
The system comprise a sonar (1) installed below the water level, a control centre (4), with a monitoring and controlling computer (17) and a wireless communication module (18) embedded, and an external power supply (5) for the control centre (4). The control centre (4) is installed above the water level. The sonar (1) is connected by a power/signal cable (14) to the monitoring and controlling computer (17) of the control centre (4), and it is equipped with a hydroacoustic transducer (10), with a controller (12), and with a positioning mechanism (11) for the position of the hydroacoustic transducer (10).
