[0037] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figure 1-5 As shown, an OPGW excess cable winding and fixing device of the present invention comprises a mounting frame 1, a plurality of insulating cable forks 2 and a fixing mechanism 3, which is used to wind and fix the OPGW excess cable on an existing building component 4.

[0039] The mounting frame 1 is used to carry other components. Components such as an optical cable splicing box and an isolating switch for OPGW optical cables are also installed on the mounting frame 1, which are all prior arts.

[0040] The insulating cable fork 2 is used to coil the OPGW surplus cable, and a plurality of insulating cable forks 2 are fixedly arranged on the mounting frame 1 .

[0041] like Figure 5As shown, a plurality of insulating cable forks 2 are arranged in a circular array around the center line of the mounting frame 1. Preferably, four insulating cable forks 2 are provided. A winding groove is provided at one end of the insulating cable fork 2 away from the center line of the mounting frame 1, so that the OPGW residual cable can be clamped in the winding groove for fixation; at the same time, a plurality of limit rods are detachably fixed in the winding groove, so that the OPGW residual cable in the winding groove is spaced into multiple strands.

[0042] The fixing mechanism 3 is used to fix the mounting frame 1 on the building component 4. The fixing mechanism 3 includes two fixing frames 31 and two connecting frames 32. The two fixing frames 31 are arranged opposite to each other and are respectively arranged against the two sides of the building component 4. One of the fixing frames 31 is fixed on the mounting frame 1; the two ends of the connecting frame 32 are respectively detachably fixed to the side of the two fixing frames 31 away from the building component 4, and the two fixing frames 31 and the two connecting frames 32 are alternately arranged in a ring shape; Figure 1 and Figure 5 As shown, by connecting the two fixing frames 31 with two connecting frames 32, one side of the two fixing frames 31 can always be in full contact with the outer side of the building component 4, so that the contact area between the two is always maximized, thereby ensuring the firmness of the fixing mechanism 3 and the building component 4.

[0043] like Figure 2 As shown, the connecting frame 32 includes two adjusting plates 321, two fastening plates 322 and connecting bolts 323, wherein the two adjusting plates 321 are detachably fixed on the two fixing frames 31 respectively; the fastening plates 322 are fixedly arranged on the adjusting plates 321 and correspond to them one by one, the fastening plates 322 are perpendicular to the adjusting plates 321, and the combined structure of the two is L-shaped; the connecting bolts 323 penetrate the two fastening plates 322 and are abutted and fixed thereto; the connecting bolts 323 are respectively abutted against the sides of the two fastening plates 322 away from the other fastening plates 322, and the two fastening plates 322 can be tightened, thereby tightening the ends of the two adjusting plates 321 and the two fixing frames 31 to fix the fixing mechanism 3 on the building component 4; because the fastening plates 322 are perpendicular to the adjusting plates 321, the axis of the connecting bolts 323 can be parallel to the side of the building component 4 at this position, so as to avoid the rotation of the connecting bolts 323 from colliding with the building component 4, thereby improving the operation convenience of the connecting bolts 323.

[0044] At the same time, by rotating the nut in the connecting bolt 323, the distance between the two fastening plates 322 can be adjusted, thereby adjusting the distance between the two fixing frames 31, so that the inner diameter of the fixing mechanism 3 can be slightly adjusted according to the different specifications of the building component 4.

[0045] like Figure 2As shown, the fixing mechanism 3 also includes a fixing bolt 33. A plurality of fixing holes 301 are provided on the fixing frame 31 and the adjusting plate 321. The fixing bolt 33 passes through one of the fixing holes 301 on the fixing frame 31 and one of the fixing holes 301 on the adjusting plate 321, and is abutted and fixed with the fixing frame 31 and the adjusting plate 321; that is, after the fixing bolt 33 passes through the fixing frame 31 and the adjusting plate 321, it abuts against a side of the fixing frame 31 away from the adjusting plate 321 and a side of the adjusting plate 321 away from the fixing frame 31, respectively, so as to achieve a fixed connection between the fixing frame 31 and the adjusting plate 321; and since a plurality of fixing holes 301 are provided on the fixing frame 31 and the adjusting plate 321, the fixing bolt 33 can pass through the fixing holes 301 at different positions, so as to adjust the distance between the two fixing frames 31, so that the inner diameter of the fixing mechanism 3 can be greatly adjusted according to the different specifications of the building component 4.

[0046] like Figure 3 As shown, the fixing bolt 33 is abutted against the side of the fixing frame 31 against the building component 4, so that the fixing bolt 33 will protrude from the side of the fixing frame 31 against the building component 4. When the building component 4 is made of concrete, the end of the fixing bolt 33 will be squeezed into the building component 4 to strengthen the connection tightness between the fixing mechanism 3 and the building component 4. When the building component 4 is made of hard materials such as metal, in order to prevent the fixing bolt 33 from affecting the fit between the fixing frame 31 and the building component 4, a fixing bolt 33 with a relatively small end thickness should be selected, or one end of the fixing bolt 33 should be directly fixed on the fixing frame 31 and flush with the side close to the building component 4.

[0047] A plurality of fixing bolts 33 , preferably two fixing bolts 33 , are disposed between each adjusting plate 321 and the fixing frame 31 , which can not only prevent the adjusting plate 321 and the fixing frame 31 from rotating, but also make the structure of the fixing mechanism 3 more streamlined.

[0048] like Figure 3 As shown, the mounting frame 1 includes a main frame 11, a support frame 12 and an assembly bolt 13, wherein a sliding hole 101 is opened on the main frame 11, and the sliding hole 101 is preferably an oblong hole, and the insulating cable fork 2 is fixedly arranged on the main frame 11; one of the fixing frames 31 is fixedly arranged on the support frame 12; the assembly bolt 13 passes through the support frame 12 and the sliding hole 101, and is abutted and fixed with the main frame 11 and the support frame 12, that is, the assembly bolt 13 is respectively abutted against the side of the support frame 12 away from the main frame 11 and the side of the main frame 11 away from the support frame 12, so that the main frame 11 and the support frame 12 are fixed; the assembly bolt 13 is slidably connected with the sliding hole 101, so that when the assembly bolt 13 is loosened and it is not abutted and fixed with the main frame 11 and the support frame 12, the assembly bolt 13 can be allowed to slide in the sliding hole 101 to adjust the relative position of the insulating cable fork 2 and the fixing mechanism 3, so that the device can adapt to different working conditions.

[0049] The building component 4 is usually a rectangular column or a rectangular beam, so it is preferred that the fixing frame 31 and the connecting frame 32 are enclosed in a rectangular ring so that the fixing mechanism 3 can be adapted to the common building component 4; and in order to improve the fixing firmness of the OPGW cable winding fixing device and the building component 4, it is preferred to provide multiple fixing mechanisms 3.

[0050] In order to avoid mutual interference between the fixing mechanism 3 and the insulating cable fork 2 and facilitate the connection between the fixing mechanism 3 and the building component 4 , the insulating cable fork 2 and the fixing mechanism 3 are preferably arranged on two sides of the mounting frame 1 opposite to each other.

[0051] The fixing mechanism 3 further includes an auxiliary bracket 34, one end of which is detachably fixed to the fixing frame 31, and the other end of which is used to install components such as insulators or voltage limiting devices, so as to support and fix the components such as insulators and voltage limiting devices on the building component 4. The insulators and voltage limiting devices are both used to connect with the OPGW optical cable. Figure 4 The connection structure between the auxiliary bracket 34 and the insulator is shown in FIG. The connection of components such as the voltage limiting device is similar to it.

[0052] like Figure 4 As shown, the auxiliary bracket 34 includes a contact portion 341, a mounting portion 342 and a redirecting portion 343, wherein the contact portion 341 is abutted against the fixing frame 31 and detachably fixedly connected thereto, and the contact portion 341 is preferably fixed to the fixing frame 31 by means of fixing bolts 33 and one or more fixing holes 301; the mounting portion 342 is fixedly disposed on the contact portion 341, and is used for fixedly connecting to equipment such as insulators and voltage limiting devices, and the mounting portion 342 is perpendicular to the contact portion 341. By utilizing the abutment between the contact portion 341 and the fixing frame 31, not only can the mounting portion 342 and the fixing frame 31 be conveniently connected and fixed, but also the strength of the connecting structure between the mounting portion 342 and the fixing frame 31 can be improved to avoid bending.

[0053] The turning part 343 is also used for fixed connection with equipment such as insulators and voltage limiting devices. The turning part 343 is fixedly set at one end of the mounting part 342 away from the abutting part 341 and is perpendicular to it, that is, the setting direction of the turning part 343 is different from the setting direction of the mounting part 342. By combining the two, it can be connected with components such as insulators and voltage limiting devices in different directions.

[0054] The method of using the OPGW excess cable coiling and fixing device of the utility model is as follows:

[0055] First, according to the specifications of the building component 4, the fixing bolts 33 are passed through the fixing holes 301 at appropriate positions, and then the two connecting bolts 323 are removed, so that the two fixing frames 31 are relatively pressed against the outer side of the building component 4, and then the connecting bolts 323 are installed between two adjacent fastening plates 322 to fix the cable winding fixture on the building component 4, and finally the OPGW cable is wound on the insulating cable fork 2 and connected to components such as the optical cable splicing box.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
