Description

Technical Field

[0001] This utility model relates to the field of submersible pump cable technology, specifically a high-performance oil-resistant submersible pump cable. Background Technology

[0002] In addition to being able to extract crude oil by submerging into wells, submersible pumps can also be used to transport water or other liquids. Currently, most of the submersible pumps used are limited by factors such as cable design or materials, which prevent the heat from being dissipated in time. This not only affects the normal power supply of the cable, but may also pose a safety hazard to surrounding equipment and personnel.

[0003] For example, application number 201721247296.2 describes a movable core steel tube sheath oil-resistant submersible pump cable, which adopts a double insulation structure, a stainless steel sheath layer and a galvanized steel tape armor layer. It has good resistance to external force damage and good resistance to complex environments. Severe vibration will not damage the main structure of the cable. The stainless steel sheath layer and galvanized steel tape armor layer of the cable may have a certain hindering effect on heat conduction, making it difficult for heat to be transferred from the copper core wire to the external environment. However, its cable has a cylindrical integrated structure. As the contact time with oil increases and the oil penetration intensifies, the outer sheath will gradually lose its original toughness and strength, becoming fragile and brittle, and difficult to replace. Even a light touch with external force may cause cracks or even breakage, exposing the internal insulation layer and conductor. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance, oil-resistant submersible pump cable to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance oil-resistant submersible pump cable, comprising an outer protective sleeve, an inner rubber sheath, and separator strips. The outer protective sleeve has anti-slip grooves evenly spaced on both its upper and lower sides. A disassembly mechanism is provided inside the outer protective sleeve. This disassembly mechanism positions the outer protective sleeve and the inner rubber sheath on both sides, separating the outer protective sleeve from the copper core wires inside. The outer protective sleeve is replaced after wear and deformation. A heat dissipation mechanism is provided inside the inner rubber sheath. This heat dissipation mechanism uses multiple sets of separator strips inside the inner rubber sheath to separate the copper core wires, preventing heat accumulation inside the inner rubber sheath when the copper core wires come into contact with oil, thus avoiding impact on the operation of the submersible pump.

[0006] As a preferred technical solution, the disassembly mechanism includes positioning holes, fasteners, inner rubber, heat dissipation holes, and nuts. The positioning holes are symmetrically opened on the outer side of the outer protective sleeve. Fasteners are connected through the outer side of the outer protective sleeve. An inner rubber is provided inside the outer protective sleeve. Heat dissipation holes are opened at equal intervals on the outer side of the inner rubber. Nuts are heat-pressed to both sides of the inner rubber. The inner rubber is located inside the outer protective sleeve.

[0007] As a preferred technical solution, the inner rubber sheet is connected to the tail end of the fastener via nuts that are spaced at equal intervals.

[0008] As a preferred technical solution, the outer side of the outer protective sleeve is set parallel to the nut through positioning holes that are opened at equal intervals.

[0009] As a preferred technical solution, the heat dissipation mechanism includes copper core wires, separators, thermally conductive silicone pads, raised strips, wiring channels, and slots. The copper core wires are evenly spaced inside the inner sheath, and separators are provided between the copper core wires. Raised strips are provided on both the upper and lower sides of the separators, and slots are connected to the outer sides of the raised strips. The arc-shaped portions on both sides of the separators are in contact with the thermally conductive silicone pads, and the wiring channels are opened through the middle of the separators.

[0010] As a preferred technical solution, the inner rubber sheet is connected to the protrusion through symmetrically opened grooves at the inner end, and the inner rubber sheet and the protrusion are arranged parallel to each other.

[0011] As a preferred technical solution, the separator strip is bonded to the copper core wire through symmetrically arranged thermally conductive silicone sheets.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model effectively dissipates the heat generated by the copper core wire through a heat dissipation mechanism, preventing heat accumulation inside the inner rubber sheath. It separates the outer protective sleeve from the inner rubber sheath and the copper core wire, making it easy for users to remove the damaged outer protective sleeve and replace it with a new one without having to disassemble and replace the entire cable on a large scale. This helps maintain the cable operating at a suitable temperature, preventing problems such as deterioration of insulation material performance and accelerated aging of copper core wires due to excessive temperature, ensuring the stable operation of the submersible pump, and reducing the risk of failure caused by overheating.

[0013] 2. This utility model utilizes the heat dissipation mechanism inside the inner rubber sheath in conjunction with the dividing strip. The dividing strip separates the copper core wires, which not only avoids the copper core wires from tangling and rubbing together, reducing the risk of insulation damage caused by friction, but also increases the space for air circulation, which helps the heat dissipation mechanism to better dissipate heat.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a high-performance oil-resistant submersible pump cable, including an outer protective sleeve 1, an inner rubber sheath 5, and separator strips 10. The outer protective sleeve 1 has anti-slip grooves 2 evenly spaced on both its upper and lower sides. The outer protective sleeve 1 has a disassembly mechanism 8 inside, which positions the outer protective sleeve 1 and the inner rubber sheath 5 on both sides, separating the outer protective sleeve 1 from the copper core wire 7 inside, and replacing the outer protective sleeve 1 after wear and deformation. The inner rubber sheath 5 has a heat dissipation mechanism 9 inside, which uses multiple sets of separator strips 10 inside the inner rubber sheath 5 to separate the copper core wire 7, preventing heat accumulation inside the inner rubber sheath 5 when the copper core wire 7 comes into contact with oil, thus avoiding impact on the submersible pump's operation.

[0019] Specifically, the arc-shaped portions on both sides of the separator 10 are in contact with the thermally conductive silicone sheet 11. This contact structure allows the separator 10 to stably contact the copper core wire 7, firmly separating the copper core wire 7 in its respective positions and preventing the wire from shifting, tangling, or rubbing inside the cable.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the disassembly mechanism 8 includes positioning holes 3, fasteners 4, inner rubber sheets 5, heat dissipation holes 6, and nuts 14. The positioning holes 3 are symmetrically opened on the outer side of the outer protective sleeve 1. Fasteners 4 are connected through the outer side of the outer protective sleeve 1. The inner rubber sheet 5 is provided inside the outer protective sleeve 1. Heat dissipation holes 6 are opened at equal intervals on the outer side of the inner rubber sheet 5. Nuts 14 are heat-pressed to both sides of the inner rubber sheet 5. The inner rubber sheet 5 is located inside the outer protective sleeve 1. The inner rubber sheet 5 is connected to the tail end of the fastener 4 through the nuts 14 that are set at equal intervals. The outer side of the outer protective sleeve 1 is parallel to the nuts 14 through the positioning holes 3 that are set at equal intervals.

[0021] The inner rubber sleeve 5 is heat-pressed together on both sides, and the nuts 14 are connected to the tail end of the fasteners 4. This connection method provides a stable mechanical connection. The heat-pressing connection ensures a tight connection between the nuts 14 and the inner rubber sleeve 5, preventing loosening. The fit between the fasteners 4 and the nuts 14 further enhances the reliability of the connection. When it is necessary to replace the worn and deformed outer protective sleeve 1, the operator can separate the outer protective sleeve 1 from the inner rubber sleeve 5 and the multiple sets of copper core wires 7 without using complicated tools and cumbersome steps. Simply loosen the fasteners 4 to easily remove the outer protective sleeve 1.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heat dissipation mechanism 9 includes copper core wires 7, separators 10, thermally conductive silicone pads 11, protrusions 12, wiring channels 13, and slots 15. The copper core wires 7 are evenly spaced inside the inner rubber sheath 5. Separators 10 are provided between the copper core wires 7. Protrusions 12 are provided on both the upper and lower sides of the separators 10. Slots 15 are connected to the outer sides of the protrusions 12. The arc-shaped portions on both sides of the separators 10 are in contact with the thermally conductive silicone pads 11. The wiring channels 13 are opened through the middle of the separators 10. The inner rubber sheath 5 is connected to the protrusions 12 through the symmetrically opened slots 15 at its inner end. The inner rubber sheath 5 and the protrusions 12 are arranged parallel to each other. The separators 10 are in contact with the copper core wires 7 through the symmetrically arranged thermally conductive silicone pads 11.

[0023] Among them, the separator strips 10 are evenly spaced between the copper core wires 7 to separate them and avoid close contact between the wires. Multiple air circulation channels are formed inside the inner rubber sheath 5, and air can flow freely in these channels, which helps to carry away the heat generated by the copper core wires 7, thereby effectively reducing the temperature inside the cable.

[0024] The working principle of this utility model is as follows: During installation, the positioning hole 3 serves a precise positioning function, providing an accurate location for the fastener 4 and ensuring that the fastener 4 can accurately align with the nut 14. After the outer protective sleeve 1 is placed over the inner rubber sleeve 5, the installation point of the fastener 4 can be quickly determined through the positioning hole 3. The operator inserts the fastener 4 into the positioning hole 3, so that the tail end of the fastener 4 connects with the nut 14, thereby locking the fastener 4 to both sides of the outer protective sleeve 1 and the inner rubber sleeve 5. When the cable is in operation, the copper core wire 7 generates heat, which is transferred to the inner sheath 5 and the surrounding space. The heat dissipation holes 6 provide a channel for heat dissipation, allowing air to circulate outside the inner sheath 5 and carry away the heat. The inner sheath 5 is connected to the protrusions 12 on the separator strip 10 via the slot 15, fixing the separator strip 10 inside the inner sheath 5. The separator strip 10 is attached to the outer sheath of the copper core wire 7 via thermally conductive silicone pads 11 on both sides. The operator inserts the copper core wire 7 into the gap between the two sets of separator strips 10. At the same time, a cable tray 13 is provided in the middle of the separator strip 10. Small diameter communication cables can be inserted into the cable tray 13, or other cables can be inserted into the cable tray 13 without needing to be placed inside. The cable tray 13 serves to dissipate heat through air circulation. The copper core wire 7 transfers heat to the outer insulating rubber, and then the heat is conducted to the separator strip 10 through the thermally conductive silicone sheet 11.
