Description

Technical Field

[0001] The utility model relates to the technical field of instrument cables, in particular to an instrument cable for offshore oil platforms. Background Art

[0002] Marine instrument cables, including communications and instrumentation cables, are suitable for use on various river and sea vessels, offshore oil and gas vessels, and other aquatic structures. They are used to transmit voice signals and can serve as connectors for marine instruments and control equipment, transmitting industrial electronic signals. Marine instrument cables have high performance requirements and are required to exhibit excellent resistance to heat, fire, flame, oil, moisture, and seawater, as well as excellent electrical and mechanical properties.

[0003] However, when such offshore instrument cables in the prior art are used, due to the complex offshore conditions and frequent sliding vibrations, the cables are very susceptible to pulling. As a result, the connection between the cable and the cable connector is subject to sudden pulling. Although the connection between the cable and the cable connector is reinforced, it is still easily damaged after being pulled multiple times. Therefore, to address this problem, there is a need for an improved instrument cable for offshore oil platforms. Utility Model Content

[0004] The purpose of the present utility model is to provide an instrument cable for offshore oil platforms to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an instrument cable for an offshore oil platform, comprising an instrument body, a slot fixedly provided in the middle of the surface of the instrument body, a plug movably engaged with the inside of the slot, a cable fixedly provided on the outer surface of the plug, a protective mechanism for protecting the connection between the cable and the plug provided between the outer surface of the cable and the instrument body, the protective mechanism comprising a fixing ring, a connecting rope, a screw, a mounting ring, and a threaded sleeve, a fixing ring fixedly provided on the outer surface of the cable, a connecting rope fixedly provided on the surface of the fixing ring, a screw fixedly provided at one end of the connecting rope, a mounting ring fixedly provided on the outer surface of the instrument body, and a threaded sleeve provided inside the mounting ring.

[0006] Preferably, the connecting rope is made of elastic rubber material. The connecting rope made of elastic rubber material can use its own elasticity to pull a part of the cable so that the reserved length of the cable end is bent and stored near the plug. In this way, when the cable is pulled, the connecting rope is first stretched. When the connecting rope is completely stretched and can no longer be stretched, it can no longer be buffered. Then the cable is continued to be pulled, and this force is also continued to be transmitted to the connecting rope, thereby effectively protecting the connection between the cable and the plug. In this way, the cable structure of the present device can be more suitable for complex marine environments; until the connecting rope is broken and the cable is continued to be pulled to make the cable taut and straight, the connection between the cable and the plug will be subjected to force.

[0007] Preferably, threaded holes are provided on both sides of the slot surface, and fixing blocks are fixedly provided on both sides of the plug surface. The fixing block surface has mounting holes, and the plug and the slot can be stably fixed together by combining the mounting holes and the threaded holes with locking screws.

[0008] Preferably, the outer surface of the threaded sleeve is provided with anti-skid protrusions, which can increase the friction force of the outer surface of the threaded sleeve, thereby facilitating the rotation of the threaded sleeve.

[0009] Preferably, a reinforcement block is fixedly provided between the cable and the plug, and the structural strength between the cable and the plug can be increased by the reinforcement block.

[0010] Preferably, the threaded sleeve is movably engaged with the interior of the mounting ring through an annular groove, so that the threaded sleeve cannot fall off from the interior of the mounting ring, but can rotate relative to the mounting ring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The device of the utility model can use its own elasticity to pull a part of the cable through the connecting rope made of elastic rubber material so that the reserved length of the cable is bent and stored near the plug. In this way, when the cable is pulled, the connecting rope is first stretched. When the connecting rope is completely stretched and can no longer be stretched, it can no longer be buffered. Then, the cable is continued to be pulled, and this force is also continuously transmitted to the connecting rope, thereby effectively protecting the connection between the cable and the plug. In this way, the cable structure of the device can be more suitable for complex marine environments.

[0013] 2. When the device needs to be disassembled, the screw can be removed by rotating the threaded sleeve, and then the plug can be plugged in and out normally. In this way, the device is easy to operate and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the 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.

[0019] See also Figure 1-3 The utility model provides a technical solution: an instrument cable for an offshore oil platform, comprising an instrument body 1, a slot 2 fixedly provided on the middle part of the surface of the instrument body 1, a plug 3 movably engaged with the inside of the slot 2, a cable 4 fixedly provided on the outer surface of the plug 3, a protective mechanism for protecting the connection between the cable 4 and the plug 3 is provided between the outer surface of the cable 4 and the instrument body 1, the protective mechanism comprising a fixing ring 5, a connecting rope 6, a screw 7, a mounting ring 8, and a threaded sleeve 9, a fixing ring 5 fixedly provided on the outer surface of the cable 4, a connecting rope 6 fixedly provided on the surface of the fixing ring 5, a screw 7 fixedly provided at one end of the connecting rope 6, a mounting ring 8 fixedly provided on the outer surface of the instrument body 1, and a threaded sleeve 9 provided inside the mounting ring 8.

[0020] The connecting rope 6 is made of elastic rubber material. The connecting rope 6 made of elastic rubber material can use its own elasticity to pull a part of the cable 4 so that the reserved length of the cable 4 is bent and stored near the plug 3. In this way, when the cable 4 is pulled, the connecting rope 6 is first stretched. When the connecting rope 6 is fully stretched and can no longer be stretched, it can no longer provide buffering. Then, the cable 4 is continued to be pulled, and this force is also continuously transmitted to the connecting rope 6, thereby effectively protecting the connection between the cable 4 and the plug 3. In this way, the cable 4 structure of the present device can be more suitable for complex marine environments. Only when the connecting rope 6 is broken and the cable 4 is continued to be pulled to make the cable 4 taut and straight, the connection between the cable 4 and the plug 3 is subjected to force.

[0021] Threaded holes 10 are provided on both sides of the surface of the slot 2, and fixing blocks 11 are fixedly provided on both sides of the surface of the plug 3. The surface of the fixing block 11 has mounting holes 12. The mounting holes 12 and the threaded holes 10 are used in conjunction with locking screws to stably fix the plug 3 and the slot 2 together.

[0022] The outer surface of the threaded sleeve 9 is provided with anti-skid protrusions, which can increase the friction force of the outer surface of the threaded sleeve 9, thereby facilitating the rotation of the threaded sleeve 9;

[0023] A reinforcement block 13 is fixedly provided between the cable 4 and the plug 3 to increase the structural strength between the cable 4 and the plug 3.

[0024] The threaded sleeve 9 is movably engaged with the mounting ring 8 through the annular groove, so that the threaded sleeve 9 cannot fall off from the mounting ring 8, but can rotate relative to the mounting ring 8.

[0025] Working principle: When using this device, the connecting rope 6 made of elastic rubber material can use its own elasticity to pull a part of the cable 4 so that the reserved length of one end of the cable 4 is bent and stored near the plug 3. In this way, when the cable 4 is pulled, the connecting rope 6 is first stretched. When the connecting rope 6 is completely stretched and can no longer be stretched, it can no longer be buffered. Then the cable 4 is continued to be pulled, and this force is also continuously transmitted to the connecting rope 6, thereby effectively protecting the connection between the cable 4 and the plug 3. In this way, the cable 4 structure of this device can be more suitable for complex marine environments. Only when the connecting rope 6 is broken and the cable 4 is continued to be pulled to make the cable 4 taut and straight, will the connection between the cable 4 and the plug 3 be subjected to force, and this formation condition is relatively harsh.

[0026] At the same time, when the device needs to be disassembled, the screw 7 can be removed by rotating the threaded sleeve 9, and then the plug 3 can be plugged in and out normally. In this way, the device is easy to operate and can be promoted and used.
