Non-slip-ring type underwater cable car transmitted by digital signal

Abstract

This digital signal transmitted flip-ring-free underwater cable carriage comprises of coaxially connected a major cable wheel and a transitional wheel which are located to the frame by the bracket bearing, the fixed wheel coaxially fastened to the other end of the bracket and loaded with the transitional wheel with a pulley arm between them, and the pulley equipped with a pulley and a movement compensation spring, through which the pulley links with the pulley arm; An analog digital converter circuit is loaded at the linkage of the transducer cable and transitional cable of the main cable, with one end of the transducer cable connected with the power of the transducer, the other end of the transducer cable connected with the analog digital converting electric circuit, which changes the collected analog signal of the transducer to digital signal. The digital signal is transmitted to signal processor for treatment through the transitional cable and pre enwind the transitional cable to the transitional wheel in the same winding direction of the cables on the major cable wheel, and the other end of the transitional cable connected to the signal processor. This cable carriage is simple in structure and reliable of signals.

Description

technical field [0001] The invention relates to an underwater cable car, in particular to a non-slip ring type underwater cable car that adopts digital signal transmission. Background technique [0002] In underwater experiments, surveys of oceans, lakes, rivers, etc., and oil well detection, it is often necessary to send transducers for signal acquisition into water or oil wells to obtain necessary signals. Transducers placed at the bottom of the water or at the bottom of the well transmit the detected signals to the ship or the ground for signal processing through long cables. A cable car is a machine that releases or retracts cables. Simply put, the cable car is driven by a motor to rotate a large cable wheel, and one end of the cable is fixed on the cable wheel, and the cable is released or retracted as the cable wheel rotates. Generally, hundreds of meters of cables are needed in marine surveys and oil well inspections, and the weight of the cables alone is several hu...

Problems solved by technology

[0006] The object of the present invention is to propose a slip ring-free underwater cable car; it does not need plug-in joints or slip rings, but fixes one end of the cable on the cable wheel of the cable car, which can be directly connected to the cable car without rotating with the cable release or recovery. It is connected with signal processing equipment or instruments, thereby solving the defect that the existing technology passes through the slip ring system, and the signal will introduce noise interference; and the watertightness of the slip ring is also very high; thus providing a The analog / digital signal conversion technology is used to convert the collected analog signal into a digital signal, and then transmit the non-slip ring underwater cable car using digital signal transmission. The underwater cable car makes the signal reliable. The reliability is greatly improved, and the possibility of signal interference during transmission is further reduced
