[0027] The technical solution of the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it. However, the embodiments given are not intended to limit the present utility model. In this embodiment, it should be understood that the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0028] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in the present utility model are only for the purpose of illustration.

[0029] This embodiment provides a cable guiding and protecting device, as Figures 1 to 3 shown, including a base 1 and a trumpet-shaped towing cable frame 2. The base 1 is provided with a through hole 3, a cross beam 4 and a stop member 5. The cross beam 4 is sleeved with a catheter 6 that is slidably connected to it, and the catheter 6 can rotate around the cross beam 4. The stop member 5 is used to limit the rotation angle of the catheter 6. The catheter 6 is used for the cable 9 to pass through, and the axial direction of the catheter 6 is arranged along the axial direction of the through hole 3;

[0030] One end of the cable towing frame 2 with a smaller diameter is connected to the base 1, and the flared channel of the cable towing frame 2 is docked with the through hole 3 for the cable 9 extending from the conduit 6 to pass through. The base 1 is used to connect to the fixing structure at the joint of the cable 9.

[0031] In this utility model, by arranging a cross beam 4 and a stopper 5 on the base 1, the conduit 6 is slidably connected to the cross beam 4, and the conduit 6 can rotate around the cross beam 4. The cable 9 passes through the conduit 6, enabling the cable 9 to move left and right and swing up and down following the conduit 6, thus having multi-dimensional degrees of freedom. The rotation angle of the conduit 6 is restricted by the stopper 5, enabling the cable 9 to be moderately adjusted at the joint, and at the same time, it can also prevent the cable 9 from swinging significantly, effectively avoiding the cable 9 from being worn due to bumping and jamming, and the cable 9 will not be directly pulled, thereby fixing the angle of the cable 9 at the joint and protecting the cable 9 and its joint.

[0032] By arranging the flared cable towing frame 2, the cable 9 can be kept away from the equipment body, avoiding the cable 9 from directly contacting the equipment body and getting scratched, and it can also guide the cable 9 to extend out of the equipment body to avoid entanglement. Therefore, when a relatively long cable, such as an umbilical cable, is connected to the joint on the equipment, the problem that the umbilical cable will sag and rest on the equipment body, being prone to wear and being easily damaged due to the rotation and entanglement of the umbilical cable can be solved.

[0033] Preferably, as Figure 4 shown, the conduit 6 is provided with a base 7, and the base 7 is provided with a through adjustment hole 8. The cross beam 4 passes through the adjustment hole 8 and is slidably connected to the conduit 6. In this embodiment, by arranging the cross beam 4, the size of the base 7 can be controlled to ensure that the axis of the conduit 6 is basically coincident with the central axis of the through hole 3. During installation, in this embodiment, the cross beam 4 can be first passed through the adjustment hole 8 on the base 7, and then the two ends of the cross beam 4 are connected to the base 1. Of course, in other embodiments, the cross beam 4 can be quickly passed through the adjustment hole 8 and restricted within the adjustment hole 8 through the structural design of conventional means, which will not be listed one by one here. The outer contour of the cross section of the cross beam 4 is circular, such as a cylinder or a circular tube. The cross beam 4 has a degree of freedom perpendicular to its axial direction within the adjustment hole 8, that is, when the cross beam 4 is located within the adjustment hole 8, there is a certain radial gap between the peripheral edge of the adjustment hole 8 and the corresponding peripheral surface of the cross beam 4. It can be understood that this gap should not be too large, so that the base 7 has a certain swinging space relative to the cross beam 4 to achieve a small swing. Preferably, the adjustment hole 8 is waist-shaped.

[0034] Furthermore, as Figures 1 to 3As shown, the stopper 5 is parallel to the crossbeam 4. When the axial direction of the conduit 6 is parallel to the axial direction of the through hole 3, the base 7 is located between the stopper 5 and the conduit 6, and the end of the base 7 abuts against the stopper 5, which can prevent the base 7 from continuing to rotate and causing the cable 9 at the joint to be twisted, thereby damaging the joint and the cable 9.

[0035] In another preferred embodiment, as Figure 5 shown, the conduit 6 includes a connecting pipe 601. End pipes 602 are respectively arranged at both ends of the connecting pipe 601. The inner diameter of the end pipe 602 increases along its axial direction, and the end with the smaller inner diameter of the end pipe 602 is butted against the connecting pipe 601. Specifically, the axial length of the conduit 6 is not less than three times the diameter of the cable 9, so as to effectively guide the cable 9. The inner diameter of the end with the larger inner diameter of the end pipe 602 is not less than twice the diameter of the cable 9 to ensure the circumferential movement space of the cable 9. The inner diameter of the connecting pipe 601 should be slightly larger than the diameter of the cable 9 so that it can smoothly penetrate through the connecting pipe 601 and extend out from both ends of the connecting pipe 601.

[0036] The towing cable frame 2 includes a plurality of skeletons 201 arranged at intervals along the circumference of the through hole 3. One end of the skeleton 201 is connected to the base 1, and the other end extends along a smooth curve. Moreover, the diameter of the cross-section of the towing cable frame 2 increases along its axial direction from the end connected to the base 1 to the other end; the skeletons 201 are connected by connecting rings 202 arranged at intervals along the axial direction. Further, the ends of adjacent skeletons 201 away from the base 1 are connected by rollers 203 arranged along the circumferential direction, so that the cable 9 and the towing cable frame 2 are in rolling friction, effectively avoiding damage caused by sliding friction of the cable 9. The surface of the roller 203 is preferably a soft nylon layer. The rings formed by the rollers 203 can be multiple, and are arranged at intervals along the extension direction of the skeleton 201 from its end (i.e., the end away from the base 1) to the starting end (i.e., the end connected to the base 1). It can be understood that the rollers 203 are arranged at least within the contact length range of the cable 9 and the towing cable frame 2. Preferably, the skeleton 201 is arc-shaped, and the radius of the arc is not less than the turning radius of the cable 9 to avoid damage to the cable 9 due to excessive bending. Among them, the turning radius of the cable 9 can be selected with reference to relevant industry standards.

[0037] The cable guiding and protecting device in the above embodiments can be applied to large and small equipment on land and in air transportation, and can also be applied to the guiding of umbilical cables or other cable types for power supply and communication of large and small underwater equipment.
