A fixed-length pay-off mechanism for coils

Abstract

The invention provides a fixed-length paying-off device used for a cable ball. The fixed-length paying-off device comprises a cable ball shell, a cable outlet nozzle, an upper end plate, a cable ball,a lower end plate, cable binding rods and a cable clamp. The cable ball shell, the upper end plate and the lower end plate form a cable ball container used for supporting and protecting the cable ball. The cable outlet nozzle is mounted on the upper end plate, a cable is pulled out from a center hole of the cable outlet nozzle, and the cable outlet nozzle is used for guiding and buffering the cable and reducing abrasion of the cable. The cable binding rods are key structures for achieving staged paying off; when needing to be wound to a specific length, the cable is pulled out from a corresponding hole in the lower end plate to be wound on one cable binding rod by multiple circles and then continues to be wound to form the cable ball, the cable is wound at all stages in this way, the paying-off length from the corresponding cable binding position to the current position is marked, and finally, the cable is evenly wound on the cable clamp. When the paying-off length is set according torequirements in use, the cable binding rods corresponding to the paying-off length and within the range of the paying-off length are pulled out, and thus, fixed-length paying off of the cable ball isachieved.

Description

technical field [0001] The invention relates to a coil fixed-length pay-off mechanism, which is suitable for setting different length gears for continuously laid coils to realize the fixed-length pay-off function. Background technique [0002] The communication buoy for underwater vehicles is a miniaturized cross-media network communication node. After the tube is launched from the water, it moves towards the water surface under the action of positive buoyancy. After reaching the water surface, the buoy is separated into two parts: the surface floating section and the sinking detection segment, and the two segments are connected by wired communication. The sonar carried by the detection section performs underwater acoustic communication with the underwater vehicle, and the digital communication module and the Beidou module carried by the floating section transmit the information sent by the underwater vehicle to the surface ship or shore-based platform, thereby realizing the...

Problems solved by technology

This patented solution requires special customization of the cable, and requires the control of the solenoid valve. It cannot be guaranteed whether the trip is successful, and the untripped rope end is easy to fall off from the load-bearing rod during the vibration process, and it is difficult to reliably determine the cable. deployment length

The whole device increases the complexity of the system, which will inevitably lead to a substantial increase in cost under the premise of ensuring reliability
