Problems solved by technology

At this time, the following two problems will be caused: one is that when the force on the cable suddenly increases and it is forcibly pulled off, the cable dragged at the tail of the vehicle may suddenly bounce off and damage the rear deck at the moment the cable is pulled off The second is that even if the cable is not broken, due to the sudden increase of the drag force and the small tonnage of the vehicle, the operating posture of the vehicle may be broken, and even an overturning accident may occur in severe cases, resulting in casualties

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] This embodiment provides a safety release mechanism applied to a high-speed towing body. The mechanism is installed on the retractable winch on the navigating body and connected to one end of the underwater towline. The other end of the underwater towline is wound around the retractable Put it on the winch. During normal operation, the cable drum on the winch is recovered or the towline is released to achieve the smooth deployment of the underwater towed carrier into the water or recovered to the vehicle body; when the towed carrier encounters an unexpected situation, the drag force suddenly increases , the mechanism can reliably separate the towline from the retractable winch on the vehicle, thereby protecting the safety of the operators on the vehicle.

[0028] The specific structure of the safety release mechanism is as follows: figure 1 As shown,...

Abstract

The invention discloses a safe releasing mechanism which comprises a connecting shell, a retaining ring, a movable spring seat, a flexible chuck, a spring, an inner sleeve, an outer sleeve, a breakable pin, a fixing ring, a tow rope, a tapered slider, a compression sleeve and the like. The safe releasing mechanism is mounted on a winch of a navigation body in high-speed navigation, and absorbs certain impact energy to reduce influences of internal impact to a take-up towing system when an underwater carrier connected with the navigation body encounters accidents and then towing tension of the tow rope is increased. When the towing tension is increased to certain value, the breakable pin in the mechanism is broken off under the action of the towing force, so that the towing rope can be reliably separated from the winch, the high-speed navigation body can navigate normally, overturning accidents are avoided, and injuries of operators due to breakage of cables can also be avoided.

Description

technical field [0001] The invention relates to a safety release mechanism, in particular to a safety release mechanism applied to a high-speed drag body. Background technique [0002] At present, countries around the world are vigorously developing marine environment monitoring and underwater detection equipment for different needs and purposes, or equipment for removing dangerous underwater explosives, in order to safeguard maritime rights and interests and ensure the normal navigation of trading merchant ships or scientific research ships. How these devices are used, and how they are deployed and recovered, should be determined according to the actual performance and functions of the devices or equipment, and the methods and methods are diverse. However, for some equipment with special functions or special requirements, the commonly used method is towing, that is, the detection equipment or the equipment for removing underwater dangers is towed behind the mother ship by a...
