Description

Technical Field

[0001] This utility model relates to the field of pile shoe monitoring technology for jack-up platform ships, and in particular to a wire harness protection device for pile shoe sensors on jack-up platform ships. Background Technology

[0002] Currently, the feasibility of the pile insertion and extraction process for self-elevating platform vessels both domestically and internationally largely relies on manual experience to judge the completion of preloading and pile driving, lacking reliable monitoring methods. This results in self-elevating platform vessels having excessively long preloading times or insufficient judgment of pile driving effects under some silty seabed conditions, making operation impossible. Construction tends to be conservative, affecting operational efficiency. Therefore, it is necessary to install sensors on the pile shoes for monitoring to improve construction efficiency.

[0003] To ensure monitoring effectiveness, multiple sensors need to be installed on the jack-up platform's pile shoes. The wires on these sensors are connected to the corresponding equipment on the jack-up platform via composite cables. Due to the harsh marine environment, the sensor wires are prone to the following problems: (1) Seawater corrosion: The wires are easily corroded when exposed to seawater for a long time, which leads to a decline in their electrical and mechanical properties and affects the normal operation of the sensors; (2) Mechanical compression and impact: In the marine environment, the sensor wires may be subjected to compression and impact from marine organisms, floating objects, and mud, resulting in wire damage or breakage. Therefore, due to the special nature of the marine environment, the protection of sensor wires becomes particularly important.

[0004] Conventional protective measures have the following shortcomings: (1) The sealing is unreliable, and seawater is prone to seepage at the connection between the conductor and the composite cable; (2) The protective sleeve is not strong enough and cannot effectively resist mechanical impact and compression; (3) The materials used in the protective sleeve cannot provide long-term corrosion resistance. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wire harness protection device for a self-elevating platform ship pile shoe sensor that can reliably protect the wires for a long time.

[0006] The present invention adopts the following technical solution:

[0007] This utility model provides a wire harness protection device for a pile shoe sensor on a self-elevating platform ship, including a sensor wire harness, a composite cable, a protective inner liner, and a protective sleeve. The sensor wire harness and the composite cable are connected by adhesive bonding. The protective inner liner is threaded and fixed on the composite cable, and the protective inner liner seals the connection between the composite cable and the sensor wire harness. The protective sleeve is fitted over the sensor wire harness, the composite cable, and the protective inner liner.

[0008] Preferably, the sensor lead harness and composite cable are bonded together using a vulcanizing adhesive dispensing process.

[0009] Preferably, the protective liner is made of stainless steel or a polymer.

[0010] Preferably, it also includes an outer protective shell, which is installed outside the protective inner liner, and the openings at both ends of the outer protective shell are respectively sealed and connected to the protective sleeve.

[0011] Preferably, the openings at both ends of the outer protective shell are sealed to the protective sleeve via flanges.

[0012] Preferably, the outer protective shell is made of austenitic cold-worked stainless steel, martensitic stainless steel or precipitation-hardening stainless steel.

[0013] Preferably, the gap between the protective inner liner and the outer protective shell is filled with a dense, flexible filler.

[0014] Preferably, the flexible filler includes flexible epoxy resin and flexible silicone, with the flexible silicone sealing the axial opening at the bottom of the outer protective shell and supporting the flexible epoxy resin above.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The wire harness protection device for the self-elevating platform shipboard pile shoe sensor of this utility model has an additional protective inner liner inside the protective sleeve. The protective inner liner seals the connection between the composite cable and the sensor wire harness, thereby providing protection for the connection between the composite cable and the sensor wire harness through the protective inner liner, avoiding damage to the wires caused by external mechanical impact and soil compression, and thus providing reliable protection for the wires for a long time.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0024] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] See Figure 1 This embodiment provides a wire harness protection device for a pile shoe sensor on a self-elevating platform ship, including a sensor wire harness 1, a composite cable 2, a protective inner liner 3, and a protective sleeve 4. The sensor wire harness 1 and the composite cable 2 are bonded together by an adhesive 5. The protective inner liner 3 is threaded and fixed onto the composite cable 2, and the protective inner liner 3 seals the connection between the composite cable 2 and the sensor wire harness 1. The protective sleeve 4 is fitted over the sensor wire harness 1, the composite cable 2, and the protective inner liner 3.

[0028] In this embodiment, the wire harness protection device for the self-elevating platform shipboard pile shoe sensor has an additional protective inner liner 3 inside the protective sleeve 4. The protective inner liner 3 seals the connection between the composite cable 2 and the sensor wire harness 1, thereby providing protection for the connection between the composite cable 2 and the sensor wire harness 1 through the protective inner liner 3, avoiding damage to the wires caused by external mechanical impact and soil compression, and thus reliably protecting the wires for a long time.

[0029] Preferably, the sensor wire harness 1 and the composite cable 2 are bonded together using a vulcanizing adhesive with a quick-drying adhesive dispensing process. This allows the connection between the sensor wire harness 1 and the composite cable 2 to quickly cure and form a tight sealing structure in a short time, effectively preventing seawater from entering the connection and thus protecting the wires from corrosion. This method is particularly suitable for environments where the wire harness is immersed in seawater for extended periods.

[0030] Preferably, the protective inner liner 3 is made of stainless steel or a polymer. Considering the sealing and corrosion protection requirements in the marine environment, when the protective inner liner 3 is made of stainless steel, it not only ensures effective sealing but also has excellent corrosion resistance; when the protective inner liner 3 is made of polymer, it not only ensures effective corrosion protection but also has good sealing performance and is lightweight. The specific material of the protective inner liner 3 can be flexibly selected according to the site requirements.

[0031] Preferably, see Figure 1 In this embodiment, the wire harness protection device for the pile shoe sensor on the self-elevating platform ship also includes an outer protective shell 6. The outer protective shell 6 covers the outside of the protective inner liner 3, and the openings at both ends of the outer protective shell 6 are respectively sealed and connected to the protective sleeve 4. The outer protective shell 6 can further enhance the protection effect on the connection between the sensor wire harness 1 and the composite cable 2, and better prevent damage to the wires from external mechanical impacts and soil compression.

[0032] Preferably, see Figure 1 The openings at both ends of the outer protective shell 6 are sealed to the protective sleeve 4 via flanges 7.

[0033] Preferably, the outer protective shell 6 is made of austenitic cold-work hardening stainless steel, martensitic stainless steel, or precipitation-hardening stainless steel. Austenitic cold-work hardening stainless steel, martensitic stainless steel, or precipitation-hardening stainless steel are all stainless steels with significantly higher strength than general-purpose austenitic stainless steel, i.e., high-strength stainless steel. The outer protective shell 6 is made of high-strength stainless steel, which allows the extremely high strength of this material to resist seawater corrosion while ensuring the long-term use of the outer protective shell 6 in harsh environments.

[0034] Preferably, see Figure 1 The gap between the inner protective liner 3 and the outer protective shell 6 is filled with a dense flexible filler 8, so that after the outer protective shell 6 fails, the flexible filler 8 acts as a protective layer to prevent the wire from being damaged by the squeezing and abrasion of mud and sand particles.

[0035] Preferably, the flexible filler 8 comprises flexible epoxy resin and flexible silicone. The flexible silicone seals the axial opening at the bottom of the outer protective shell 6 and supports the flexible epoxy resin above it. The flexible epoxy resin has high fluidity, which ensures that the flexible filler 8 can fill every corner of the gap when filling the gap between the inner protective liner 3 and the outer protective shell 6. After the flexible epoxy resin cures, it forms a flexible protective layer, providing comprehensive protection for the inner protective liner 3.

[0036] In summary, the wire harness protection device for the pile shoe sensor on the self-elevating platform vessel of this utility model, through its multi-layered protection design, meets the usage requirements of the self-elevating platform vessel under the harsh environmental conditions of frequent pile insertion and removal, effectively extends the service life and reliability of the sensor wires, reduces the frequency of maintenance and replacement, and lowers operating costs.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
