Description

Technical Field

[0001] The utility model relates to a self-breaking protection quick plug-in type stern rope connector. Background Art

[0002] The towing stern rope is a common component installed at the stern of an underwater towing device to maintain a stable position during towing and recovery. It primarily consists of a connecting mechanism and a resistance rope segment. Existing towing stern ropes typically connect to the towing device using a Bulleit ferrule or transition flange and multiple fasteners. The resistance rope segment is often made of polyurethane or other non-metallic materials and fashioned into a triangular cone before being connected to the rope segment, increasing the stern rope's towing resistance. When connected to the device via a Bulleit ferrule, friction and vibration between the stern rope and the towing device during towing due to seabed currents and towline excitation create noise, impacting data collection from the underwater towing device. When the stern rope is connected to the device via a flange, repeated installation and removal of tightening screws is tedious. Furthermore, when connected using a Bulleit ferrule or flange, the stern rope's drag force increases dramatically if it becomes entangled with obstacles during towing, potentially damaging the towing device or even the entire towing system. Utility Model Content

[0003] The purpose of the utility model is to provide a self-breaking protection quick-plug stern rope connector, which is used to solve the problems of cumbersome work of connecting the stern rope to the equipment through the flange, and the stern rope getting entangled with obstacles during the towing process, resulting in a sharp increase in the towing force of the stern rope, which is easy to cause damage to the towing equipment or even the entire towing system.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] The self-breaking protection quick-plug stern rope connector includes a plug and a socket. The plug includes a fixed seat. One end of the stern rope is fixedly connected to the fixed seat. A plurality of protection pins are fixedly connected to the fixed seat. The socket includes a connecting tube. One end of the connecting tube is connected to the wet end device. The other end of the connecting tube is used to be inserted into the fixed seat. A plurality of spiral hook grooves corresponding to the protection pins are provided on the connecting tube. An elastic member for pushing the protection pin against the end of the spiral hook groove is provided in the connecting tube.

[0006] The elastic member includes a flange sleeve installed in the connecting pipe, one end of the flange sleeve is equipped with a top cover, and the other end is provided with a first flange extending inward, a top cap is provided in the first flange, and the top cap is located in the flange sleeve and has a second flange extending outward at one end, a spring is provided in the flange sleeve, and the two ends of the spring respectively rest on the top cover and the top cap.

[0007] A shock-absorbing pad is fixedly connected to the top cap.

[0008] A circle of cutting grooves is provided on the protection pin, and the spiral hook groove is clamped in the cutting groove.

[0009] The beneficial effects of the utility model are:

[0010] (1) This patent solves the cumbersome steps of installing the stern rope through fasteners, and can realize the rapid installation of the stern rope of the equipment.

[0011] (2) After the stern rope is fixed by spring rebound and compression shock-absorbing pad, the problem of metal collision and abnormal noise caused by the traditional method of adding the stern rope by hook during towing is solved, which is more conducive to data collection and signal processing during the towing process of the equipment.

[0012] (3) When the towing stern rope becomes entangled with a seabed obstacle and the towing force increases sharply to the design value, the plug protection pin is pulled off and the stern rope can be detached from the equipment by itself, thus protecting the equipment for safe recovery.

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the self-breaking protection quick-plug stern rope connector includes a plug 300 and a socket 200. The plug 300 includes a fixing seat 303. One end of the stern rope 400 is fixedly connected to the fixing seat 303 by epoxy resin. A plurality of protection pins 301 are fixedly connected to the fixing seat 303. The socket 200 includes a connecting tube 201. One end of the connecting tube 201 is connected to the wet end device 100. The other end of the connecting tube 201 is used to be inserted into the fixing seat 303. A plurality of spiral hook grooves 206 corresponding to the protection pins 301 are provided on the connecting tube 201. An elastic member is provided in the connecting tube 201 for pushing the protection pins 301 against the ends of the spiral hook grooves 206.

[0022] Working principle: The plug 300 connected to the towing stern rope 400 is installed into the socket 200. The protective pin 301 of the plug 300 compresses the internal elastic part along the spiral hook groove 206. After it is in place, the elastic part rebounds and pushes the protective pin 301 into the end of the spiral hook groove 206. During the towing process, when the stern rope 400 is entangled with the seabed obstacle, the tension of the stern rope 400 increases sharply. After the shear resistance of the protective pin 301 reaches the preset value, the protective pin 301 is broken, and the stern rope 400 is separated from the equipment, thereby protecting the wet end equipment 100 for safe towing and recovery.

[0023] The elastic member comprises a flange sleeve 202 mounted within a connecting tube 201. One end of the flange sleeve 202 is fitted with a top cover 208, and the other end is provided with an inwardly extending first flange 204. A top cap 209 is mounted within the first flange 204. The top cap 209, located within the flange sleeve 202, has an outwardly extending second flange 203 at one end. The first and second flanges 204 and 203 restrain the top cap 209, preventing it from being ejected. A spring 207 is mounted within the flange sleeve 202, with its ends resting against the top cover 208 and top cap 209, respectively. A shock-absorbing pad 205 is fixedly attached to the top cap 209. The spring 207's rebound compression of the shock-absorbing pad 205 secures the stern rope 400, eliminating the metal-on-metal noise issue associated with conventional hook-mounted stern ropes 400 during towing. This facilitates data acquisition and signal processing during the towing process.

[0024] The protective pin 301 is provided with a circular groove 302, into which the spiral hook groove 206 is locked. This structure uses the groove 302 as a pre-breaking point. If the towing stern rope 400 becomes entangled with a seabed obstacle, causing the towing force to increase sharply to the designed value, the protective pin 301 of the plug 300 is pulled apart at the groove 302, and the stern rope 400 can be automatically separated from the equipment, protecting the equipment from damage caused by the huge tension caused by the entanglement of the stern rope 400 and ensuring safe equipment recovery.

[0025] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be regarded as limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
