Description

Technical Field

[0001] The present application relates to the technical field of ground anchor devices, and in particular to a retractable spiral ground anchor device with an anchor plate for emergency stopping of power transmission lines. Background Art

[0002] China is a global leader in transmission line galloping disasters. With the continued expansion of power grid coverage and the rise in extreme weather events, the frequency and impact of power line galloping incidents are increasing significantly. Annual large-scale galloping incidents have resulted in significant direct economic losses and social impacts.

[0003] Current measures to control transmission line galloping include installing interphase spacers, double-swing anti-gallop devices, and twistable sub-spacers. For lines experiencing galloping and without anti-galloping devices, insulated cables can be used to pull the galloping transmission line conductors and anchor them to the ground, achieving reliable emergency gallop arrest. Line galloping exerts significant pulling force on anti-galloping devices, so a key aspect of implementing emergency gallop arrest is establishing secure and reliable anchor points in the ground to ensure they do not break free under extreme galloping conditions. Summary of the Invention

After the ground anchor device is rotated into the ground to a certain depth, the anchor plate can be rotated and extended through a rotating component, thereby expanding the diameter of the anchor plate, increasing the contact area between the anchor plate and the underground, and improving the stability of the ground anchor device.

[0015] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0016] Unless the context requires otherwise, throughout the specification and claims, the term "including" is to be interpreted as having an open, inclusive meaning, that is, "including, but not limited to." In the description of the specification, the terms "one embodiment," "some embodiments," "exemplary embodiments," "examples," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with the embodiment or example is included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials, or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0017] The embodiment of the present invention provides a retractable spiral ground anchor device for emergency stopping of power transmission lines, such as Figure 1-2 As shown, it includes: an inner rod 1, an outer rod 2, an anchor plate 3, a rotating component 4 and a support arm 5.

[0018] In some embodiments, the inner rod 1 is a long rod-shaped structure, the outer rod 2 is wrapped around the outside of the inner rod 1, one end of the outer rod 2 is set as a conical structure, and the anchor plate 3 is set on the outside of the outer rod 2 and has a spiral structure.

[0019] Exemplarily, the inner rod 1 and the outer rod 2 are only in contact with each other and can move independently without interfering with each other. In this way, when the inner rod 1 rotates, the outer rod 2 will not rotate accordingly.

[0020] For example, an operating handle (not shown) is provided at the end of the outer rod 2 away from the conical structure. Thus, by applying a rotational force to the outer rod 2 through the handle, the outer rod 2 passes through the conical structure, i.e., the anchor point, and penetrates into the ground, and the anchor plate 3 then enters the ground for anchoring.

[0021] In some embodiments, the rotating component 4 is disposed between the inner rod 1 and the outer rod 2 and fixedly connected to the inner rod 1 ; one end of the support arm 5 is slidably connected to the rotating component 4 , and the other end is fixedly connected to the anchor plate 3 .

[0022] For example, a rotating handle (not shown) is provided at the end of the inner rod 1 away from the conical structure. Since the rotating member 4 is fixedly connected to the inner rod 1, rotating the inner rod 1 by rotating the handle can drive the rotating member 4 to rotate synchronously, thereby pushing the support arm 5 to slide on the rotating member 4. The support arm 5 pushes the anchor plate 3, causing the anchor plate 3 to extend away from the outer rod 2, thereby achieving the effect of retracting the anchor plate 3.

[0023] The present invention provides a retractable spiral ground anchor device for emergency stopping of power transmission lines. Before the ground anchor device is drilled into the ground, the anchor plate is rotated into the ground to a certain depth and locked by an operating handle. Then, the rotating part is rotated by rotating the handle, and the anchor plate is extended away from the outer rod through the support arm, thereby expanding the force-bearing diameter of the anchor plate, increasing the contact area between the anchor plate and the ground, and improving the stability of the ground anchor device.

[0024] In some embodiments, an arc-shaped groove 41 is provided on the rotating component 4 , and one end of the support arm 5 is slidably disposed in the arc-shaped groove 41 .

[0025] Exemplarily, a sliding rod is provided at one end of the support arm 5, and the sliding rod is fixedly arranged in the arc groove 41. In the initial state, the sliding rod is located in the arc groove 41 close to the inner rod 1. When the rotating part 4 rotates, the sliding rod slides in the arc groove 41 and slides to a position in the arc groove 41 away from the inner rod 1. At this time, the support arm 5 pushes the anchor plate 3, so that the anchor plate 3 extends in the direction away from the outer rod 2, so as to achieve the retractable effect of the anchor plate 3.

[0026] In some embodiments, the outer rod 2 is provided with a limiting hole 21, and the support arm 5 is slidably disposed in the limiting hole 21. Thus, when the support arm 5 slides in the arc-shaped groove 41, the support arm 5 also moves in the limiting hole 21, ensuring that the movement direction of the support arm 5 is perpendicular to the direction of the outer rod 2, so that the support arm 5 can push the anchor plate 3 to extend away from the outer rod 2, thereby achieving a retractable effect of the anchor plate 3.

[0027] In some embodiments, the anchor disc 3 is a segmented anchor disc 3, and multiple anchor discs are regularly distributed outside the outer rod 2. In this way, the contact area between the anchor disc 3 and the ground can be increased to increase the stability of the ground anchor device.

[0028] In some embodiments, multiple rotating components 4 and support arms 5 are provided, and there is a one-to-one correspondence between the rotating components 4 and the support arms 5. That is, one rotating component 4 is connected to only one support arm 5, so that when the rotating component 4 rotates, it can drive the support arm 5 connected thereto to move, thereby pushing the anchor plate 3 through the support arm 5.

[0029] In some embodiments, one anchor plate 3 is fixedly connected to two or more support arms 5. Since the anchor plate 3 has a spiral structure and is not on the same plane, providing one anchor plate 3 with two or more support arms 5 fixedly connected thereto ensures that when the rotating component 4 rotates, the anchor plate 3 is pushed outward away from the outer rod 2 by the multiple support arms 5, thereby achieving a retractable effect of the anchor plate 3.

[0030] Exemplarily, multiple rotating parts 4 are dispersedly arranged between the inner rod 1 and the outer rod 2 along the direction of the inner rod 1 and the outer rod 2. In this way, the multiple rotating parts 4 and the multiple support arms 5 can push the multiple anchor plates 3 to achieve a telescopic effect.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
