Description

Technical Field

[0001] The present invention relates to the technical field of cable equipment, and in particular to a deicing cable and a method for using the same. Background Art

[0002] Cables are typically installed on at least two towers. Winter snowfall often causes ice to form on the cables, necessitating manual de-icing. When the ice isn't thick, de-icing workers often use ice-breaking rods to knock on the cables, effectively breaking the ice. Using an ice-breaking rod to knock on the cables is difficult to control; too little force can be insufficient to break the ice, while too much can be physically demanding and may even damage the cables or the ice-breaking rod. Furthermore, as the knocking continues, broken ice can fall and injure the de-icers (broken ice can fall and injure them). Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a deicing cable, which solves the problem in the prior art that the deicing force of the cable is difficult to control and easily causes injuries to the deicing personnel.

[0006] The de-icing cable provided by the present invention has the following innovation, namely, an auxiliary cable is added next to the cable through two sliding rings fixed on the cable. When ice forms, the ice layer wraps around the cable and the auxiliary cable. During de-icing, the auxiliary cable can be pulled through the extra auxiliary cable ends at both ends of the cable, so that the auxiliary cable and the cable move relative to each other to break the ice layer wrapped around them. At this time, the de-icing personnel do not need to be directly under the cable, thus avoiding injury to the de-icing personnel and at the same time will not cause damage to the cable.

[0007] Furthermore, the sliding ring includes an inner bracket, which is provided with a plurality of support holes. The cable includes a plurality of inner cores that pass through the plurality of support holes respectively. The cable also includes a cortex wrapped around all the inner cores. The sliding ring also includes an outer ring that surrounds the cortex and is fixedly connected to the inner bracket. The outer ring is provided with a sliding hole for the auxiliary cable to pass through. A metal sliding sleeve is fixedly connected in the sliding hole, and the auxiliary cable is slidably connected to the metal sliding sleeve.

[0008] Furthermore, the inner bracket includes a central ring and a pair of connecting arms fixedly connected to the central ring. The two connecting arms pass through the cortex and are fixedly connected to the outer ring. Several pairs of sub-rings are also fixedly connected to the central ring. There are support holes in the sub-rings and the central ring.

[0009] Furthermore, one of the pair of secondary rings is fixedly connected to a first arc-shaped plate that abuts against the inner wall of the cortex, and the center line connecting the two first arc-shaped plates and the two connecting arms form a "cross" structure.

[0010] Furthermore, the two connecting arms are fixedly connected to second arc-shaped plates that respectively abut against the inner walls of the cortex.

[0011] Furthermore, a pair of ring ears are symmetrically provided on both sides of the outer ring, and a metal sliding sleeve is fixedly installed on each ring ear. The auxiliary cables are two metal sliding sleeves respectively passing through the two metal sliding sleeves on the same side of the cable.

[0012] Furthermore, the middle section of the auxiliary cable is also provided with a spike located between the two sliding rings.

[0013] Furthermore, a rotating drum for bending one end of the auxiliary cable is fixedly connected to the tower, and a winch is installed on the tower below the rotating drum; two motors are also installed in the tower to drive the two winches on the tower respectively.

[0014] Furthermore, the auxiliary cables are two cables respectively passing through two metal sleeves located at the crossing sides of the electric cables.

[0015] According to an embodiment of the present invention, a method for using the above-mentioned de-icing cable is also provided. When the de-icing cable is in use, a pair of sliding rings and two auxiliary cables are respectively provided on the cable line between each two adjacent towers. The two ends of each auxiliary cable are respectively connected to the adjacent winch, and the motor is started to synchronously tension the two auxiliary cables, or the motor is started to make the two auxiliary cables move synchronously.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] During de-icing, de-icing personnel can stay away from the ice-falling point, thus avoiding damage to de-icing personnel caused by broken ice. At the same time, the installed auxiliary cable can also improve the connection strength between the cable and the tower, and can be more stable when the cable is frozen, so it will not be broken by thick ice. The auxiliary cable can be operated at the tower, so there is no need to carry out mobile operations along the cable, and the de-icing efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, 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 should not be understood as limiting the present invention.

[0032] like Figure 1 As shown, this embodiment provides a deicing cable, which includes a cable 1 installed between two towers 2. The cable 1 is fixedly connected to at least a pair of sliding rings 3. A secondary cable 4 is slidably arranged between the two sliding rings 3, wherein the length of the secondary cable 4 is greater than the distance between the two sliding rings 3.

[0033] The deicing cable also includes at least one pair of winches 5 for respectively winding the two ends of the auxiliary cable 4. The two ends of the cable 1 are respectively installed on the two towers 2, and the two winches 5 are respectively installed on the two towers 2. The auxiliary cable 4 and the winch 5 are detachably connected.

[0034] The de-icing cable provided by the present invention has the following innovation, namely, an auxiliary cable 4 is added next to the cable 1 through two sliding rings 3 fixed on the cable 1. When ice forms, the ice layer wraps around the cable 1 and the auxiliary cable 4. During de-icing, the auxiliary cable 4 can be pulled through the extra ends of the auxiliary cable 4 at both ends of the cable 1, so that the auxiliary cable 4 and the cable 1 move relative to each other to break the ice layer wrapped around them. At this time, the de-icing personnel do not need to be directly under the cable 1, thereby avoiding injury to the de-icing personnel and at the same time will not cause damage to the cable 1.

[0035] like Figure 1 、 2As shown, in order to reduce the influence of the pulling of the auxiliary cable 4 on the cable 1, the sliding ring 3 includes an inner bracket, which is provided with a plurality of support holes. The cable 1 includes a plurality of inner cores 6 that pass through the plurality of support holes respectively. The cable 1 also includes a cortex 7 wrapped around all the inner cores 6. The sliding ring 3 also includes an outer ring 8 that surrounds the cortex 7 and is fixedly connected to the inner bracket. A sliding hole is provided on the outer ring 8 for the auxiliary cable 4 to pass through. A metal sliding sleeve 9 is fixedly connected in the sliding hole. The auxiliary cable 4 is slidably connected to the metal sliding sleeve 9. That is, the cable 1 is an inner core 6 and a cortex 7 wrapped around the inner core 6. At the same time, an insulating layer 10 is filled between the cortex 7 and the inner core 6. These structures are the main structures of the cable 1. Multiple support holes are set on the inner bracket for each inner core 6 to pass through. The inner bracket and the outer ring 8 surrounding the cortex 7 form a sliding ring 3 for the auxiliary cable 4 to move. When the auxiliary cable 4 moves, the outer ring 8 and the inner bracket are used as the moving basis, which has little impact on the inner core 6 and the cortex 7. At the same time, the metal sleeve 9 is used for the auxiliary cable 4 to slide, making it easier to pull the two. In particular, the sliding ring 3 is close to the tower 2, and you can first use an ice rod to knock on the metal sleeve 9 to break the ice layer here, and then continue to pull the auxiliary cable 4.

[0036] like Figure 1 、 2 As shown, in order to further improve the stability of the cable 1, the inner bracket includes a center ring 11 and a pair of connecting arms 12 fixedly connected to the center ring 11, the two connecting arms 12 pass through the cortex 7 and are fixedly connected to the outer ring 8, and a number of pairs of auxiliary rings 13 are fixedly connected to the center ring 11, and the auxiliary rings 13 and the center ring 11 both have support holes, wherein a pair of auxiliary rings 13 are also fixedly connected to a first arc-shaped plate 14 that is against the inner wall of the cortex 7, and the line connecting the centers of the two first arc-shaped plates 14 and the two connecting arms 12 form a "cross" structure, and the two connecting arms 12 are also fixedly connected to a second arc-shaped plate 15 that is respectively against the inner wall of the cortex 7, and the first arc-shaped plate 14 and the second arc-shaped plate 15 are arranged to hold the cortex 7 open. When the auxiliary cable 4 is pulled, the relative position between the inner bracket and the cortex 7 is more stable, and the inner core 6 is also more stable, in order to In order to make the de-icing efficiency higher, two auxiliary cables 4 are provided, that is, a pair of ring ears 16 are symmetrically provided on both sides of the outer ring 8, and a metal sleeve 9 is fixedly installed on each ring ear 16. The auxiliary cables 4 are two metal sleeves 9 respectively passing through the two metal sleeves 9 on the same side of the cable 1, that is, the two auxiliary cables 4 are parallel to the cable 1. The auxiliary cables 4 provided in this way can be in the same tensioned state as the cable 1, so that the three are parallel. When ice forms, the ice layer evenly covers the outside of the three, so that the ice layer can be smoothly broken when the auxiliary cables 4 are pulled. Among them, the provided connecting arm 12 passes through the second curved plate 15 and then passes through the cortex 7 and is fixedly connected to the metal sleeve 9, so that the auxiliary ring 13, the center ring 11, the outer ring 8 and the metal sleeve 9 are connected as a whole, and the two auxiliary cables 4 have less impact on the inner core 6 and the cortex 7 when moving;

[0037] like Figure 1 、 2 , 3, 4, and 5, further, the auxiliary cable 4 can be a thin and flexible steel wire rope with strong supporting strength. In order to ensure that the auxiliary cable 4 can be parallel to the power cable 1 at a large distance, a plurality of arc-shaped hooks 17 are provided between the two auxiliary cables 4. Each end of the arc-shaped hook 17 is fixedly connected to a hook 18. The middle section of the arc-shaped hook 17 is mounted on the power cable 1, and the two auxiliary cables 4 are hung on the two hooks 18. The arc-shaped hooks 17 are located between two adjacent sliding rings 3 to cooperate with the sliding ring 3 to support the auxiliary cables 4.

[0038] In another embodiment, a ring 19 is fixedly connected to each end of the arc-shaped hook 17, and two auxiliary cables 4 pass through the rings 19 respectively, and the cable 1 is placed on the middle section of the arc-shaped hook 17, that is, the two auxiliary cables 4 hold up the cable 1;

[0039] In another embodiment, the auxiliary cables 4 can also be two cables respectively passing through the two metal sleeves 9 located on the crossing side of the cable 1, that is, the two auxiliary cables 4 are arranged beside the cable 1 in a cross form, wherein when the intersection is located below the cable 1, the cable 1 is placed on the two auxiliary cables 4, so that the two auxiliary cables 4 provide support for the cable 1, and at the same time make the cable 1 and the two auxiliary cables 4 close to each other. When ice forms, the ice layer wraps around the two auxiliary cables 4 and the cable 1, making deicing more convenient;

[0040] Furthermore, the two auxiliary cables 4 can be provided with intersections above and below the cable 1, that is, the two cables 1 are spirally wound around the cable 1, so that the ice layer formed is easier to break (wherein, there can be two intersections).

[0041] like Figure 1 、 6 As shown, in order to make it easier to break the ice layer on the middle section of the cable 1, the middle section of the auxiliary cable 4 is further provided with a spike 20 located between the two sliding rings 3. When the auxiliary cable 4 is pulled, the spike 20 can make the ice layer in contact with it easier to break, so that the wrapped ice layer can be efficiently broken and fallen. In particular, it is not suitable to set the middle section of the two auxiliary cables 4 in a cross manner to avoid the spike 20 making it difficult to pull the two auxiliary cables 4 relative to each other.

[0042] like Figure 1 、 7As shown, in order to improve the pulling efficiency of the auxiliary cable 4, a rotating drum 21 for bending one end of the auxiliary cable 4 is fixedly connected to the tower 2, and the winch 5 is installed on the tower 2 below the rotating drum 21. The installation height of the rotating drum 21 is similar to that of the cable 1. The auxiliary cable 4 is bent downward after passing through the rotating drum 21. When deicing is not in progress, the auxiliary cable 4 can be fixed to the tower 2 by first winding it on the rotating drum 21 and then clamping it on the winch 5.

[0043] Two motors 22 are also installed in the tower 2 to drive the two winches 5 on the tower 2 respectively. When de-icing, the auxiliary cable 4 is first disconnected from the winch 5, and then the winding between the auxiliary cable 4 and the rotating drum 21 is released (that is, the auxiliary cable 4 goes directly downward after passing through the rotating drum 21), and then the auxiliary cable 4 is connected to the winch 5. The motor 22 is started to wind the auxiliary cable 4 through the winch 5, so that the auxiliary cable 4 can move relative to the cable 1.

[0044] like Figure 1 、 8 As shown in Figures 9 and 10, in this embodiment, the rotating drum 21 includes a connecting rod 23 fixedly connected to the tower 2 and a roller 24 rotatably connected to the connecting rod 23. The surface of the roller 24 is recessed with an arc-shaped groove 25 for the auxiliary cable 4 to partially sink into. In this way, the auxiliary cable 4 is not easily separated from the rotating drum 21, ensuring that the auxiliary cable 4 can be tensioned when the motor 22 is running; further, the winch 5 includes a rotating rod 26 fixedly connected to the rotating shaft of the motor 22 and a limit plate 27 fixedly sleeved on the rotating rod 26. The limit plate 27 is separated from the side wall of the tower 2 and is rotated. A card hole 28 is provided on the end face of the rod 26, and a notch 29 connected to the card hole 28 is provided on the limit plate 27. The end of the auxiliary cable 4 is fixedly connected with a card head 30, and the card head 30 is a "7"-shaped structure that cooperates with the notch 29 and the card hole 28. When connecting the winch 5 and the auxiliary cable 4, the card head 30 is inserted into the card hole 28 and the notch 29. Specifically, the card head 30 includes a limit rod 31 that cooperates with the notch 29 and a card rod 32 that cooperates with the card hole 28. The card rod 32 and the limit rod 31 are vertically fixedly connected, and the limit rod 31 is fixedly connected to the auxiliary cable 4.

[0045] like Figures 1 to 10As shown, in another embodiment, a method for using the above-mentioned deicing cable is also provided. Specifically, a pair of sliding rings 3 and two auxiliary cables 4 are respectively provided on the cable line 1 between each two adjacent towers 2 (one auxiliary cable 4 can also be provided to achieve the deicing effect, but two auxiliary cables 4 can make the wrapped ice layer receive greater mechanical energy, and at the same time can also better improve the support effect on the cable line 1, so that the two sides of the cable line 1 are evenly stressed). When deicing is required, the two ends of each auxiliary cable 4 are respectively connected to the adjacent winch 5, and the motor 22 is started to synchronously tension the two auxiliary cables 4 (that is, the two ends of the auxiliary cable 4 are synchronously convoluted). Or start the motor 22 to make the two auxiliary cables 4 move synchronously and staggered (that is, one end of one auxiliary cable 4 is fixed and the other end is convoluted, and the end of the other auxiliary cable 4 opposite to the previous auxiliary cable 4 is fixed and the end close to it is convoluted, and at the same time, the fixed ends of the two auxiliary cables 4 can be unwound to prevent the auxiliary cables 4 from being over-tensioned after the ice layer is broken). In this way, the auxiliary cables 4 and the cable 1 are moved relative to each other, thereby breaking the ice layer wrapped around the cable 1 and the auxiliary cables 4 (when the auxiliary cables 4 are pulled, the cable 1 is in a relatively static state, and the auxiliary cables 4 move relatively, so that the ice layer wrapped around them is broken), so as to achieve the purpose of de-icing.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
