Description

Technical Field

[0001] The present application relates to the field of cables, and more specifically, to a cable armor repair device. Background Art

[0002] A large number of cables are used in offshore oil drilling platforms, among which the underwater cables go straight from the offshore platforms to the seabed, and the cables are subjected to very large tension. The outer sheath of the cable exposed to the air is easily damaged by long-term exposure to light, sea salt, moisture, etc., causing the cable armor to be exposed outside. The cable armor is woven from steel wires, and its main function is to protect the cable and enhance the cable's tensile strength. Long-term exposure causes the steel wires that form the cable armor to be corroded and broken, seriously affecting the cable's force. When the cable armor is rusted and damaged, the cable is easily broken, causing equipment damage and property loss, and even casualties in severe cases.

[0003] Generally, in order to ensure the safety of subsequent work, when the cable armor is found to be damaged, the entire cable needs to be replaced. When replacing the cable, the equipment related to the cable needs to be shut down, and a well repair team and electric pump engineers need to be hired. According to the conventional well repair operation steps, the repair time can be as long as 7 days. The outsourced construction cost is estimated to be nearly 1 million yuan, and the production of the drilling platform will be seriously affected.

The cross-sections of the first clamp 110 and the second clamp 120 are designed to be semicircular, and the upper and lower sizes of the first clamp 110 and the second clamp 120 are different, so that the first clamp 110 and the second clamp 120 are surrounded to form a first cylinder 130 and a second cylinder 140, and the first cylinder 130 and the second cylinder 140 are used to surround the cable 30. Specifically, the first cylinder 130 is located above the second cylinder 140, and a first chamber 131 is formed in the first cylinder 130, and a second chamber 141 is formed in the second cylinder 140, and the cable 30 passes through the first chamber 131 and the second chamber 141. Among them, the inner diameter d of the second cylinder 140 is the same as the outer diameter of the cable 30, so that the second cylinder 140 and the cable 30 are closely attached together, and the inner diameter D of the first cylinder 130 is larger than the inner diameter d of the second cylinder 140, so that a filling space is formed between the first cylinder 130 and the cable 30 for filling the repair material, which can realize the repair of the cable armor and prevent the cable 30 from breaking.

[0031] In some embodiments, Figure 1 and Figure 2As shown, the first clamp 110 and the second clamp 120 are connected and fixed by bolts at the first cylinder 130, and the first clamp 110 and the second clamp 120 are connected and fixed by bolts at the second cylinder 140. Specifically, the first clamp 110 is provided with a first connecting piece 111, and the first connecting piece 111 is provided with a first screw hole, and the second clamp 120 is provided with a second connecting piece 121, and the second connecting piece 121 is provided with a second screw hole 122, and the first screw hole and the second screw hole 122 are arranged oppositely, and the bolts 150 passing through the first screw hole and the second screw hole 122 connect and fix the first clamp 110 and the second clamp 120, and the bolt connection and fixation are convenient to operate and reliable. It is easy to think that in other embodiments of the present application, the first clamp 110 and the second clamp 120 can also be connected and fixed by means of snap connection or welding. Furthermore, the first clamp 110 and the second clamp 120 can be connected and fixed by multiple methods at the same time, such as the first clamp 110 and the second clamp 120 are connected and fixed by bolts at the first cylinder 130, and the first clamp 110 and the second clamp 120 are connected and fixed by snaps at the second cylinder 140.
