In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0023] Combine the following Figure 1-Figure 3 The structure and working principle of the cable guiding device provided by the present invention are described.

[0024] Figure 1 The schematic diagram of the structure of the cable guide device provided by the embodiment of the present invention is illustrated. Figure 1 A cable guiding device provided by the present invention includes a plurality of wire harness components 100, a supporting steel wire rope 200 and a plurality of guiding components 300. The plurality of wire harness components 100 are arranged at intervals, and the wire harness components 100 are used to limit the cables; the supporting steel wire rope 200 is passed through the plurality of wire harness components 100, and the supporting steel wire rope 200 is used to connect the plurality of wire harness components 100; and the plurality of guiding components 300 are arranged on the wire harness components 100, and are used to guide the wire harness components 100.

[0025] Specifically, a plurality of cable tying components 100 are arranged at intervals along the length direction of the supporting steel wire rope 200, and their function is to limit the plurality of cables individually to prevent the plurality of cables from being entangled or knotted during the lifting and lowering process. As for the arrangement of the guide component 300, each cable tying component 100 may be provided with a guide component 300, or a guide component 300 may be arranged at intervals of one or several cable tying components 100.

[0026] In the above structure, a plurality of wire harness components 100 are arranged at intervals, and each wire harness component 100 plays the role of binding the cables, ensuring that the cables will not be damaged due to friction with the surrounding environment during the lowering process. Secondly, the supporting steel wire rope 200 runs through these wire harness components 100, which is not only used to connect these wire harness components 100, but also provides additional support, enhances the stability of the entire device, and prevents the cables from shaking or twisting in a complex installation environment. Finally, a plurality of guide components 300 are arranged on the wire harness components 100. Their existence is to better guide the position of the wire harness components 100, ensure that they are smoothly lowered along a predetermined path, and avoid the lowering and lifting difficulties that may be encountered in traditional methods. The connection method of the supporting steel wire rope 200 adopts a through-type fixing method, that is, the steel wire rope passes through all the wire harness components 100, and is ensured to be firm and reliable through appropriate fastening measures. Such a connection method can effectively disperse stress and prevent overall failure caused by single point failure.

[0027] In terms of material selection, the cable harness component 100 can be made of materials with excellent low-temperature resistance, such as polytetrafluoroethylene (PTFE), epoxy phenolic glass cloth or other special engineering plastics. Such materials can maintain their mechanical strength and toughness in extremely low temperature environments, and prevent the material from being brittle due to low temperatures. Structurally, the design of multiple cable harness components 100 is not only to limit the cables, but also the spacing between each component should ensure that the cables are always supported evenly during the lowering process, reducing unnecessary bending and stress concentration, thereby reducing the possibility of wear.

[0028] In addition, the supporting steel wire rope 200 is a key component connecting each cable harness component 100, and the material used must also have high strength to ensure that it is not easy to break when subjected to tension for a long time, and at the same time it must be able to withstand the low temperature in the LNG environment.

[0029] As for the design of the guide component 300, its material must also be resistant to low temperatures, and the shape design must take into account how to accurately guide the direction of the wiring harness component 100 without direct visualization. The guide component 300 is connected to the wiring harness component 100 through a tightly fitting interface to ensure that a good positioning effect can be maintained even in a dynamic environment. In this way, the entire cable guiding device can operate reliably in a complex environment, protecting the cable from damage while ensuring the normal operation of the LNG submersible pump.

[0030] Figure 2 A cross-sectional view of a cable guiding device provided by an embodiment of the present invention is illustrated.

[0031] Reference Figure 2 In some embodiments of the present invention, the wiring harness component 100 includes a wiring harness body 110, a wiring harness cover 120 and a fastener 130. The wiring harness body 110 is provided with a plurality of limiting hole groups 140, and the limiting hole groups 140 are used to limit the cables and the supporting steel wire rope 200; the wiring harness cover 120 is provided on the wiring harness body 110, and the wiring harness cover 120 is used to cover the limiting hole groups 140; the fastener 130 is detachably provided between the wiring harness body 110 and the wiring harness cover 120, and the fastener 130 is used to lock the wiring harness body 110 and the wiring harness cover 120 so that the cables and the supporting steel wire rope 200 are fixed to the wiring harness body 110.

[0032] In the above structure, the design of the cable harness component 100 is to ensure the safety and stability of the cables and the supporting steel wire rope 200 in a complex installation environment. The cable harness body 110, as a core component, is provided with a special limiting hole group 140, which is designed to limit the cables and the supporting steel wire rope 200 to ensure that they can maintain the correct arrangement without displacement or wear in the pump well 700 without direct visualization.

[0033] The cable cover 120 is installed on the cable body 110. Its function is to cover the limit hole group 140 to form a closed structure, which can not only prevent external impurities from entering and affecting the normal operation of the cable and the supporting wire rope 200, but also protect the cable from interference from external environmental factors.

[0034] The fastener 130 is placed between the wiring harness body 110 and the wiring harness cover 120. Its main function is to connect the wiring harness body 110 and the wiring harness cover 120. Through this fastening connection mechanism, the fixation of the cables and the supporting steel wire ropes 200 inside the wiring harness body 110 is ensured, preventing them from unnecessary movement or loosening due to external forces during installation or operation, thereby ensuring the safety and reliability of the cables and the supporting steel wire ropes 200 throughout their entire use cycle.

[0035] In some possible embodiments, the size and spacing of the limit hole group 140 are precisely calculated to ensure that the cables and support wire ropes 200 can be properly embedded therein and remain locked. The design of the fastener 130 must not only consider the connection strength, but also the convenience of installation and disassembly. Through reasonable size and shape design, the fastener 130 can be easily installed and disassembled without destroying the overall structure, which is convenient for daily maintenance and inspection. The fastener 130 is specifically a bolt, and corresponding holes are also provided on the cable harness body 110 and the cable harness cover 120. The bolts penetrate the holes on the cable harness body 110 and the cable harness cover 120, and then the two are locked by nuts. This connection method not only simplifies the installation process, but also improves the stability of the overall device, ensuring that the cable can work reliably for a long time in a complex environment, thereby ensuring the smooth operation of the LNG submersible pump.

[0036] Reference Figure 2 In some embodiments of the present invention, the limiting hole group 140 includes a power cable limiting groove 141, a support wire rope limiting groove 142 and an instrument cable limiting groove 143; the power cable limiting groove 141, the support wire rope limiting groove 142 and the instrument cable limiting groove 143 are distributed on the surface of the harness body 110 at intervals. In this way, mutual insulation between cables is achieved. Among them, the power cable limiting groove 141 is used to limit the power cable 600, the support wire rope limiting groove 142 is used to limit the support wire rope 200, and the instrument cable limiting groove 143 is used to limit the instrument cable 500. In some other possible embodiments, the limiting hole group 140 also includes a lifting wire rope limiting groove 144.

[0037] Specifically, there are three power cable limit grooves 141, which are arranged at intervals on the upper surface of the harness body 110; there is one support wire rope limit groove 142, which is located in the middle of the upper surface of the harness body 110; there are two instrument cable limit grooves 143, which are arranged at intervals on one side of the upper surface of the harness body 110. There are two lifting wire rope limit grooves 144, which are arranged in the middle of the lower surface of the harness body 110. The power cable limit groove 141, the support wire rope limit groove 142 and the instrument cable limit groove 143 located on the upper surface can be covered by the harness cover plate 120. The two lifting wire rope limit grooves 144 located on the lower surface can be covered by another harness cover plate 120, or by the guide component 300. It should be noted that the number and arrangement of the power cable limiting grooves 141, the supporting wire rope limiting grooves 142, the instrument cable limiting grooves 143 and the lifting wire rope limiting grooves 144 are not limited thereto and can be designed according to actual conditions.

[0038] In the above structure, the design of the cable harness component 100 is intended to ensure the safety and stability of different types of cables and supporting steel wire ropes 200 in complex environments. The power cable limit grooves 141, the supporting steel wire rope limit grooves 142 and the instrument cable limit grooves 143 are spaced apart on the surface of the cable harness body 110, and each limit groove is designed for different types of cables. Through such a design, the cable harness body 110 can not only effectively organize and manage different types of cables and supporting steel wire ropes 200, but also ensure that they are in good condition during installation and operation in the pump well 700 without direct visualization, thereby improving the safety and maintenance efficiency of the entire system.

[0039] Specifically, the power cable limiting groove 141 is mainly used to limit the power cable 600. Through its specific shape and size design, it ensures that the power cable 600 can be accurately embedded and kept fixed during the installation process, preventing the power cable 600 from moving or wearing due to external environmental changes or mechanical vibrations.

[0040] The support wire rope limiting groove 142 is specially designed to limit the support wire rope 200, ensuring that the support wire rope 200 is fixed in position on the cable harness body 110, preventing it from shifting when subjected to tension or relaxation, thereby ensuring the stability and reliability of the support wire rope 200 during use.

[0041] The instrument cable limiting groove 143 is used to limit the instrument cable 500. By limiting the instrument cable 500, the instrument cable 500 can be effectively prevented from being damaged due to external factors in a complex environment, thereby ensuring the accuracy of instrument data transmission.

[0042] The lifting wire rope limiting groove 144 is used to limit the lifting wire rope 800, and a section of the top of the lifting wire rope 800 is reserved for movable setting. When the present invention and the pump need to be lifted from the pump well 700, the lifting wire rope 800 can be connected to the lifting device. When the present invention and the pump are installed into the pump well 700, the lifting wire rope 800 is disconnected from the lifting device.

[0043] Reference Figure 2 In some embodiments of the present invention, the length of the guide component 300 is adapted to the inner diameter of the pump well 700, ensuring that there is a gap between the guide component 300 and the pump well 700, thereby preventing jamming. The guide component 300 includes a guide plate 310 and at least two guide wheels 320. The guide plate 310 is detachably provided on the harness body 110; the guide wheels 320 are detachably provided at both ends of the guide plate 310. Specifically, the fastener 130 can be sequentially passed through the harness cover 120, the harness body 110 and the guide plate 310, so that the three are connected as a whole.

[0044] In the above structure, the guide component 300 is designed to ensure that the cable and the supporting wire rope 200 can be smoothly lowered and positioned in the pump well 700 without direct visualization. The guide plate 310 is arranged on the harness body 110. Through the connection with the harness body 110, the guide plate 310 can slide in the pump well 700 driven by the harness body 110, which can prevent the harness body 110 from hitting the inner wall of the pump well 700, thereby causing damage to the cable. At the same time, when shaking occurs, 300 will first contact the inner wall of the pump well 700, and the guide wheels 320 installed at both ends of the guide plate 310 will reduce the friction between the cable and the harness body 110 and the surrounding environment during movement through rolling contact with the pump well 700, thereby preventing wear or jamming caused by friction. The design of the guide wheel 320 not only ensures the smooth movement of the cables and the wiring harness body 110 in a complex environment, but also achieves uniform force on the cables and the supporting wire rope 200 through its arrangement at both ends of the guide plate 310, further improving their safety and stability during installation and use.

[0045] Reference Figure 2 In some embodiments of the present invention, a connecting assembly 400 is also included, and the connecting assembly 400 includes a lifting guide rod 410, an adjusting component 420 and a support plate 430. The lifting guide rod 410 is arranged on the pump well cover for connecting with the lifting equipment; the adjusting component 420 is arranged at one end of the lifting guide rod 410 for adjusting the length of the cable guide device; the support plate 430 is arranged at one end of the adjusting component 420 away from the lifting guide rod 410, and the support plate 430 is used to connect with the supporting wire rope 200.

[0046] In the above structure, one end of the lifting guide rod 410 is used to connect with the top plate of the pump well. Through the lifting guide rod 410, the cable guide device can be accurately hoisted to the specified position. Specifically, the present invention is connected to the bottom of the top plate through the lifting guide rod 410 in the working state, so that the present invention is hoisted inside the pump well 700. By rotating the adjustment component 420, the length of the device can be easily adjusted to meet the installation requirements when the deviation range of the pump well 700 is large. The support plate 430 is located at one end of the adjustment component 420 away from the lifting guide rod 410. Its design purpose is to establish a reliable connection with the support wire rope 200. The support plate 430 ensures effective contact with the support wire rope 200 through its structural design, so that the support wire rope 200 can evenly distribute stress when it is subjected to tension, avoiding the risk of breakage caused by local stress concentration. Through the synergistic effect of these three components, the connection component 400 not only realizes the convenient installation and length adjustment of the cable guide device, but also ensures the safe fixation of the support wire rope 200 in a complex environment, thereby improving the stability and reliability of the entire system.

[0047] Reference Figure 1 In some embodiments of the present invention, the lifting guide rod 410 includes a guide rod body 412 , one end of which is provided with a lifting ring 411 , and the other end of the guide rod body 412 is integrally formed with a connecting portion 413 , which is connected to the adjusting component 420 .

[0048] In the above structure, the lifting ring 411 is designed to be connected to the hook at the bottom of the manhole cover. The lifting ring 411 can be a closed ring structure, and a threaded hole is provided at the bottom end thereof, through which the guide rod body 412 is threadedly connected, and a threaded seat is provided at the bottom of the connecting part 413, and the adjusting component 420 is threadedly connected to the threaded seat.

[0049] Reference Figure 1 In some embodiments of the present invention, the adjustment component 420 includes a turnbuckle screw 422, one end of which is provided with a first locking portion 421, the first locking portion 421 is used to be detachably connected to the connecting portion 413, and the other end of the turnbuckle screw 422 is provided with a second locking portion 423, the second locking portion 423 is used to be detachably connected to the support plate 430. Specifically, the first locking portion 421 and the connecting portion 413 can be detachably connected by bolts, and the second locking portion 423 and the support plate 430 can also be detachably connected by bolts.

[0050] In the above structure, the design of the adjustment component 420 is to ensure that the cable guide device can flexibly adjust the length in the pump well 700 without direct visualization conditions and establish a reliable connection with the supporting wire rope 200. Through this connection method, the turnbuckle screw 422 can be quickly combined or separated with the lifting guide rod 410 and the support plate 430 during installation or removal, simplifying the assembly process of the entire device.

[0051] The turnbuckle screw 422 includes a central screw, rotating parts arranged at both ends of the central screw, and a locking mechanism. The central screw is the main part of the turnbuckle screw 422 and is a rod with threads. The threads allow the rotating parts at both ends to cooperate with it. The rotating parts can be rings, snap rings or other forms of connectors, which can rotate around the central screw, and each rotating part has a thread that matches the central screw. This means that when these parts are rotated, they will move forward or backward along the screw. The position of the rotating parts is locked by tightening the locking nut or the like to prevent them from rotating on their own. When the rotating parts at both ends of the turnbuckle screw 422 are rotated, these parts will move along the thread direction on the central screw. If the rotation direction is clockwise, the rotating parts will move toward the center, thereby shortening the length of the entire turnbuckle screw 422; conversely, if the rotation direction is counterclockwise, the rotating parts will move outward, thereby extending the length of the turnbuckle screw 422, thereby adjusting the length of the entire device.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
