Description

Technical Field

[0001] This utility model relates to the field of communication well technology, and in particular to an optical cable coiling device for communication wells. Background Technology

[0002] In existing communication pipeline projects, to ensure that subsequent fiber optic cable maintenance and splicing are not affected by insufficient cable length, a cable allowance must be made within the designed length range for each fiber optic cable laid. Currently, communication wells generally use... Figure 4 The optical cable winding reel, fixed to the inner wall of the communication well, winds the optical cable into multiple interconnected loops and bundles them together with straps. Sometimes, due to different sources, two or more bundles of optical cables are placed on the same optical cable winding reel. Figure 4 The optical cable winding reel uses two cross-shaped vertical and horizontal plates, with an L-shaped bending plate connected to the end of each plate. A right-angled plate connecting the bending plate to the vertical or horizontal plate is used to wind the optical cable. The other right-angled plate of the four bending plates, also called a baffle, is located in front of the plane containing the vertical and horizontal plates. The baffles are used to block the front of the optical cable, preventing it from detaching from the winding reel; relatively long baffles are generally used.

[0003] There are two drawbacks to this structure in the existing technology. First, because of the presence of the baffle, when winding the optical cable, it is necessary to pass the optical cable between the end of the baffle and the inner wall of the communication well, which increases the diameter of the winding path of the hand and arm compared with no baffle. Second, there is water at the bottom of some communication wells. When the optical cable coil is removed or moved, the bottom of the optical cable coil may fall naturally due to gravity during the movement, which is not conducive to protecting the optical cable.

[0004] Therefore, there is a need for an optical cable winding device that reduces the use of baffles and can limit the bottom of the optical cable coil. Summary of the Invention

[0005] The purpose of this invention is to provide an optical cable winding device that reduces the use of baffles and can limit the bottom of the optical cable coil.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiber optic cable winding device for a communication well includes vertical plates and horizontal plates that are cross-shaped and fixedly connected. The vertical plates are arranged vertically, and the horizontal plates are arranged horizontally. The device also includes four winding plates for winding the fiber optic cable: a first winding plate, a second winding plate, a third winding plate, and a fourth winding plate.

[0008] The front end of the first winding plate is vertically fixed with a baffle, the upper end of the vertical plate is rotationally connected with the rear end of the first winding plate, a lock piece is connected between the vertical plate and the first winding plate, the lock piece can lock the first winding plate in the front-rear direction and the baffle is vertically erected in front of the vertical plate and extends upward, and the first winding plate is turned down by 90 degrees when the lock piece is unlocked;

[0009] The lower end of the vertical plate is vertically fixed with a third winding plate and a lower extension plate respectively, and the third winding plate and the lower extension plate are arranged oppositely in up-down direction.

[0010] The left end and the right end of the horizontal plate are fixed with a second winding plate and a fourth winding plate respectively, the horizontal plate extends leftward of the second winding plate, and the horizontal plate extends rightward of the fourth winding plate.

[0011] Further, the lock piece is a 90-degree self-locking hinge.

[0012] Further, the lower extension plate is a concave arc-shaped plate.

[0013] Further, a reinforcing plate is fixedly connected between the vertical plate and the horizontal plate.

[0014] Further, the utility model also comprises a left fixed plate and a right fixed plate arranged on the left side and the right side of the vertical plate respectively, and the left end and the right end of the horizontal plate are fixed to the left fixed plate and the right fixed plate respectively.

[0015] A plurality of optical cable supporting rods extending forward are vertically fixed on the left fixed plate and the right fixed plate respectively.

[0016] Further, the left-right width of the third winding plate is smaller than the left-right width of the lower extension plate.

[0017] In the above technical solution, the utility model has the following beneficial effects:

[0018] The utility model only retains one baffle, and the optical cable can be directly wound on the first winding plate, the second winding plate, the third winding plate and the fourth winding plate, compared with the prior art of applying four baffles, the arm extension length is reduced during winding, the arm extension phenomenon is reduced, the winding diameter can be visually measured, and the winding work is more simple and labor-saving. In addition, through the arrangement of the lower extension plate, the position of the bottom of the optical cable coil is limited, even if the bundled optical cable is loosened, the risk that the bottom of the optical cable contacts the bottom of the communication well can be reduced. Finally, through the cooperation of the rotatable first winding plate and the lower extension plate, even if the optical fiber is wound too tightly, the first winding plate is turned down, the optical cable coil falls on the lower extension plate, and the optical cable can be easily taken down.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] It should be noted that the terms "above," "one end," "up," etc. used in this document indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Similar expressions are only for illustrative purposes and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "part," "two parts," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Example 1: As Figures 1-2 The optical cable coiling device for a communication well shown includes a vertical plate 1 and a horizontal plate 2 that are cross-shaped and fixedly connected. The vertical plate 1 is arranged vertically, and the horizontal plate 2 is arranged horizontally. The vertical plate 1 and the horizontal plate 2 can be fixed to the inner wall of the communication well by means of expansion screws or other connecting parts.

[0029] The optical cable coiling device further comprises four first winding plates 3, second winding plates 4, third winding plates 5 and fourth winding plates 6 for coiling the optical cable. The four winding plates are located on a circle with the intersection point as the center and are all located on the front side of the optical cable coiling device.

[0030] The front end of the first winding plate 3 is vertically fixed with a baffle 12, and the first winding plate 3 and the baffle 12 are integrally arranged in an L shape. The upper end of the stand plate 1 is rotationally connected to the rear end of the first winding plate 3, and a lock piece is connected between the stand plate 1 and the first winding plate 3. The lock piece can lock the first winding plate 3 in the front-rear direction, and the baffle 12 is vertically arranged in front of the stand plate 1 and extends upward. At this time, it is the traditional baffle position, and the baffle is vertically arranged in front of and above the stand plate. The optical cable can pass from the end of the baffle and the inner wall of the communication shaft. When the lock piece is unlocked, the first winding plate 3 is flipped down by 90 degrees.

[0031] Under the action of the lock piece, the first winding plate 3 has two positions. One is vertically arranged parallel to the stand plate, and at this time the baffle is horizontally perpendicular to the stand plate in the front-rear direction. At this time, it is beneficial to place the top end of the optical cable coil on the baffle, so that the person is low to facilitate bundling the top end or the position close to the top end of the optical cable coil. In addition, the circumferential length between the first winding plate 3, the second winding plate 4, the third winding plate 5 and the fourth winding plate 6 is smaller, the first winding plate 3 no longer supports the optical cable coil, and the optical cable no longer adheres to the first winding plate, which is also convenient for taking out the bundled or single optical cable coil from the optical cable coiling device. The second is that the first winding plate 3 is flipped up by 90°, and the front-rear direction is perpendicular to the stand plate, and the baffle is vertically arranged. At this time, the first winding plate 3 mainly plays a role of suspending the optical cable coil, and the baffle plays a role of limiting the front side of the optical cable coil.

[0032] The lock piece is used to lock the position of the first winding plate 3, which is a prior art. Alternatively, a telescopic rod with adjustable length can be used, one end of the telescopic rod is fixed on the stand plate, and the free end is hinged to the first winding plate 3. The length of the telescopic rod controls the position of the first winding plate 3.

[0033] Preferably, the lock piece is a 90-degree self-locking hinge. The first hinge of the self-locking hinge is fixed on the front side of the stand plate, and the second hinge is fixed on the side of the first winding plate 3 which can face the bottom surface of the communication shaft. The first hinge and the second hinge are hinged, and when the first hinge and the second hinge are closed, the first winding plate 3 is vertically arranged. When the first winding plate 3 is flipped up by 90°, the opening angle of the first hinge and the second hinge is locked. The structure of the self-locking hinge is a prior art, such as the Chinese utility model patent with application number CN202323470754.7.

[0034] The lower end of the vertical plate 1 is vertically fixed with the third winding plate 5 and the lower extension plate 7 respectively, and the third winding plate 5 and the lower extension plate 7 are arranged oppositely. The three are in the shape of inverted F. The optical cable coil is located between the third winding plate 5 and the lower extension plate 7, and the optical cable is tightly wound. The third winding plate can limit the position, and the first winding plate can solve the problem of taking and placing the optical cable coil. The lower extension plate 7 can support the optical cable when the optical cable is loosely wound. Therefore, the optical cable winding device with the structure has good adaptability to the tightness of the optical cable winding.

[0035] Preferably, the left and right widths of the third winding plate are smaller than the left and right widths of the lower extension plate. In this way, the lower extension plate is widened to facilitate the larger area to support the optical cable coil, preventing the bottom end of the optical cable coil from falling to the bottom of the communication well.

[0036] The left end and the right end of the horizontal plate 2 are respectively fixed with the second winding plate 4 and the fourth winding plate 6, and the horizontal plate 2 extends to the left of the second winding plate 4 and extends to the right of the fourth winding plate 6. That is, the second winding plate 4 and the fourth winding plate 6 are a certain distance away from the left end and the right end of the corresponding horizontal plate. In this way, the inner side of the optical cable coil is positioned by the second winding plate 4 and the fourth winding plate 6, and the back side will fall on the horizontal plate 2.

[0037] Preferably, the lower extension plate 7 is a concave arc plate. This is to better fit the bottom of the optical cable coil.

[0038] Preferably, a reinforcing plate 8 is fixedly connected between the vertical plate 1 and the horizontal plate 2. This is to increase the connection strength between the vertical plate 1 and the horizontal plate 2, and the number of reinforcing plates 8 can be multiple.

[0039] Example two: different from example one, the optical cable winding device further comprises a left fixed plate 9 and a right fixed plate 10 arranged on the left and right sides of the vertical plate 1, and the left and right ends of the horizontal plate 2 are respectively fixed to the corresponding left fixed plate 9 and right fixed plate 10. The left fixed plate 9 and the right fixed plate 10 are fixed to the communication well.

[0040] A plurality of optical cable support rods 11 extending forward are vertically fixed on the left fixed plate 9 and the right fixed plate 10 respectively. The left fixed plate 9 and the right fixed plate 10 serve to fix the optical cable support rods 11. Because the optical cable coil of example one is convenient to take and place, and the conflict with the optical cable passing through the optical cable support rods 11 is less, multiple optical cable support rods 11 for lapping the optical cable can be arranged outside the horizontal plate and the vertical plate.

[0041] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
