Description

Technical Field

[0001] This utility model relates to the technical field of cable dragging equipment, specifically a demagnetizing cable dragging buckle. Background Technology

[0002] Demagnetization generally refers to the demagnetization of ships. The purpose of ship demagnetization is a technical measure to weaken the magnetic field strength of a ship and improve its distribution characteristics. Demagnetization is used to enhance the ship's magnetic protection capabilities, defend against attacks from underwater magnetic weapons (such as magnetically inductive mines), and prevent detection by magnetic detection instruments, thereby ensuring the ship's navigational safety. Newly built and repaired ships, as well as ships that have served a certain period of time, all require demagnetization. There are two methods of demagnetization: temporary coil demagnetization and fixed winding demagnetization. In the temporary coil demagnetization method, a demagnetizing cable is typically wound around the hull of the ship to be demagnetized according to regulations, and electricity is passed through to eliminate the magnetic field. Demagnetization is relatively flexible when carried out at sea.

[0003] When degaussing a ship, workers need to drag the degaussing cable from the sea to the work position from both ends of the ship's side. The current method is to tie the cable to the rope and manually pull the cable up. The drawbacks are that the current method of directly tying the cable to the cable is time-consuming and labor-intensive due to the large number of cables. During the towing process, due to human factors, the rope often gets tangled with the cable. In addition, the cable end will occasionally get caught on the shell of parasitic organisms on the bottom of the ship. Forcibly pulling it will damage the cable end. Utility Model Content

[0004] The purpose of this invention is to provide a demagnetizing cable drag clip to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a demagnetizing cable drag buckle, including an installation head, a cable fixing buckle, and a protective shell. The installation head has symmetrically arranged rotating lugs on both sides of its outer wall. One end of the outer wall of the cable fixing buckle is rotatably connected to the center of the outer wall of the installation head. The cable fixing buckle and the two lugs are arranged in a triangle. The protective shell is movably sleeved on the outer wall of the cable fixing buckle. The bottom of the cable fixing buckle has an insertion groove that matches the cable head. The cable fixing buckle is inserted into the cable head through a pin.

[0006] Furthermore, the protective shell is threadedly connected to the cable fixing buckle, the inner wall of the protective shell is provided with an internal thread, and the outer wall of the cable fixing buckle is provided with an external thread that matches the internal thread.

[0007] Furthermore, the surface of the cable fixing buckle is provided with a plurality of first insertion holes that match the pins, and the surface of the cable head is provided with a plurality of second insertion holes, wherein the diameter of the first insertion holes is smaller than the diameter of the second insertion holes.

[0008] Furthermore, one end of the outer wall of the cable fixing buckle is provided with a threaded first screw, and the outer wall of the first screw is provided with a first bushing on the outside of the cable fixing buckle. The first bushing is rotatably connected to the mounting head.

[0009] Furthermore, one end of the outer wall of the lug is provided with a threaded second screw, the outer wall of the second screw is provided with a second bushing on the outside of the lug, the second bushing is rotatably connected to the mounting head, the outer wall of the second screw is provided with a threaded nut inside the mounting head, and a cover plate is provided on one side of the outer wall of the mounting head, the cover plate being fixedly connected to the mounting head by a number of screws.

The installation head provides installation space for the cable fixing buckle and the two hanging ears, while also providing rotational support for them, ensuring their safety and stability. Before dragging the cable, the protective shell is adjusted to expose the pin's installation position on the surface of the cable fixing buckle. The cable head is then inserted into the insertion groove, followed by the pin, which secures the cable head to the cable fixing buckle. The protective shell is then adjusted again, covering the cable fixing buckle and sealing the pin's installation position. Protective measures effectively ensure the installation stability of the cable fixing clip and cable head, preventing them from falling off during dragging. The rotating connection between the hanging ear and the mounting head allows the hanging ear to rotate on the mounting head after the cable is fixed to it, effectively preventing the dragging angle of the cable from adversely affecting the cable. The rotating connection between the cable fixing clip and the mounting head allows for free adjustment of the angle between the mounting head and the cable, effectively preventing damage to the cable itself due to rotation along the cable head caused by changes in the rotation angle of the mounting head.

[0013] 2. In this utility model, the cable is fixed to the two lugs of the device, eliminating the need to tie it every time.

[0028] The working principle of this utility model:

[0029] Refer to the instruction manual appendix Figures 1-6 This utility model comprises an installation head 1, a cable fixing buckle 2, a protective shell 4, hanging ears 3, a cable head 5, an insertion groove 6, and a pin 7. The installation head 1 provides installation space for the cable fixing buckle 2 and the two hanging ears 3, and also provides rotational support for the cable fixing buckle 2 and the two hanging ears 3, ensuring the safety and stability of the cable fixing buckle 2 and the two hanging ears 3. Before dragging the cable, the position of the protective shell 4 on the surface of the cable fixing buckle 2 is adjusted to expose the installation position of the pin 7. The cable head 5 is inserted into the inner side of the insertion groove 6, and then the pin 7 is inserted. The pin 7 connects and fixes the cable head 5 and the cable fixing buckle 2. Then the protective shell 4 is adjusted again, and the protective shell 4 covers the outer wall of the cable fixing buckle 2, thus securing the installation position of the pin 7. The sealed protection at the location effectively ensures the installation stability of the cable fixing buckle 2 and the cable head 5, preventing the cable head 5 and the cable fixing buckle 2 from falling off during dragging. The rotatable connection between the hanging ear 3 and the mounting head 1 allows the hanging ear 3 to rotate on the mounting head 1 after the cable is fixed on the hanging ear 3, effectively preventing the dragging angle of the cable from adversely affecting the dragging of the cable. The rotatable connection between the cable fixing buckle 2 and the mounting head 1 allows the angle between the mounting head 1 and the cable fixing buckle 2 to be freely adjusted, and the connection angle between the mounting head 1 and the cable can be freely adjusted, effectively preventing the cable itself from being damaged by rotation along the cable head 5 due to changes in the rotation angle of the mounting head 1.

[0030] The cable is fixed to the two lugs 3 of this device, so it does not need to be tied every time. The cable head 5 can be installed simply by unscrewing the protective shell 4 of this device, fixing it with the two pins 7, and then screwing the protective shell 4 back on. The lugs 3 for hanging the cable and the cable fixing buckle 2 in this device are all designed with rotating connections, so the cable will not get tangled during towing. The device has a streamlined design with no protruding parts, so it will not be affected by the complex conditions of the bottom of the boat.

[0031] This invention will greatly simplify the complexity of cable dragging and placement during demagnetization operations, ensuring that workers can drag the cable to the target area in a time-saving and labor-saving manner.
