Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of grounding pins, and in particular relates to a distribution network manual plug-in grounding pin and an operating method thereof. Background Art
[0002] At present, a large number of distribution network lines are grounded by grounding pins. According to regulations, the insertion depth of 10kV line grounding pins should not be less than 60cm. The conventional method is to knock the grounding pin into the ground with a sledgehammer, and then use the sledgehammer to knock the hole left and right when removing it. It takes a lot of effort to pull out the grounding pin that is 60cm into the ground. If the soil is hard, it will be more time-consuming and laborious. It is also easy to deform the grounding pin and form burrs. In addition, some construction workers who do not bring hammers on site use stones to knock it out horizontally, which is more likely to deform the grounding pin and make it unusable. In addition, when the grounding pin is knocked into the soil, the person holding the grounding pin is likely to be injured by the sledgehammer, which is unsafe and inefficient, and difficult to operate.

[0027] Embodiment 1:
[0028] like Figure 1 As shown, a distribution network manual plug-in type grounding pin provided in an embodiment of the present invention comprises a grounding pin body 100, wherein the cross section of the grounding pin body 100 is elliptical (eg Figure 2As shown), the front end 101 of the grounding pin body 100 is in the shape of a cone tip, and the rear end of the grounding pin body 100 is provided with an auxiliary structure, which can be a handheld handle 200, so that the operator can support the manual plug-in grounding pin of the distribution network, and the grounding pin body 100 can be hammered into the ground to a set depth by an impact device such as a hammer, and the elliptical grounding pin is easier to knock in than the round one. After the grounding pin is inserted into the ground, when the grounding pin needs to be pulled out, the grounding pin body 100 can be twisted in situ. Since the cross-section of the grounding pin body 100 is elliptical, its main axis (horizontal axis) is longer than the secondary axis (longitudinal axis), when twisting, the grounding pin hole position will inevitably form an expanded hole, so that the grounding pin body 100 is easy to pull out, and the operation process is simple, labor-saving and safe. In specific applications, the cross-section of the grounding pin body 100 can also be elliptical in shape, and such equivalent replacement also belongs to the protection scope of the present invention.
[0029] The use of the manual plug-in grounding pin of the distribution network includes the following steps: a grounding pin insertion step and a grounding pin removal step; wherein, the grounding pin insertion step includes: aligning the front end of the grounding pin body 100 with a preset point; inserting the grounding pin body 100 into the ground to a set depth, so that the ground forms a grounding hole that is in close contact with the grounding pin body 100. The grounding pin removal step includes: rotating the grounding pin body 100 to a set angle to expand the grounding hole, and then pulling out the grounding pin body 100, without the need to knock the grounding pin laterally. In specific applications, the insertion depth of the 10kV line grounding pin is not less than 60cm. When removing, there is no need to use a sledgehammer to knock left and right to expand the hole, and the grounding pin will not be deformed or have burrs formed. Since there is no need to knock laterally to pull out the grounding pin, the grounding pin is prevented from being knocked to the point of being deformed and unusable, and the use effect is good.
[0030] Specifically, the auxiliary structure includes two handles 200, which are arranged on both sides of the rear end of the grounding pin body 100. The handles 200 are arranged close to the rear end of the grounding pin body 100, and there is a certain distance between the handles 200 and the rear end of the grounding pin body 100, so that the sledgehammer can act on the rear end of the grounding pin body 100. The operator can hold the handles 200, and the operator who holds the grounding pin only needs to hold the handles 200 steadily, and it is not easy to hurt the hand if it is far away from the sledgehammer, and the safety and reliability are better.
[0031] Specifically, the two handles 200 are fixedly arranged near the rear end of the grounding pin body 100, or the handles 200 are foldably arranged on both sides of the rear end of the grounding pin body 100, and one end of the handle 200 connected to the grounding pin body 100 is provided with a self-locking structure for keeping the handle 200 unfolded to be perpendicular to the grounding pin body 100, that is, the handle 200 can be folded, and the handle 200 can be rotated and retracted to facilitate the movement and storage of the grounding pin. When the grounding pin needs to be used, the grounding pin is arranged longitudinally, and only the handle 200 needs to be rotated and unfolded, and the handle 200 is unfolded to a horizontal state, and the handle 200 is limited by the self-locking structure to keep the handle 200 in a horizontal state. When the grounding pin is inserted to a certain depth, the handle 200 can also be used as a foot pedal.
[0032] Of course, the auxiliary structure can also be a pedal, which can be flat, about 15 cm long and 5 cm wide, and can be fixed to the grounding pin body 100, or connected to the grounding pin body 100 through a rotating shaft structure and locked by a pin.
[0033] Specifically, a mounting seat 300 is provided at or near the rear end of the grounding pin body 100, and connection grooves are provided at both ends of the mounting seat 300. One end of the handle 200 extends into the connection groove and is rotatably connected to the mounting seat 300 through a rotating shaft. Specifically, the self-locking structure includes a latch, and the mounting seat 300 has a pin hole for inserting the latch. The handle 200 rotates and unfolds. After the latch is inserted into the pin hole, the handle 200 can be restricted from resetting and retracting. The handle 200 remains horizontal, and the latch realizes horizontal self-locking. The latch can be connected to the grounding pin body 100 through a hanging rope.
[0034] In a specific application, the front end of the plug pin may be provided with a rounded corner or a chamfered corner structure to facilitate insertion into the pin hole.
[0035] In some optional schemes, the connection groove passes through the upper end away from the grounding pin body 100, and the handle 200 can be rotated and retracted in the direction away from the cone tip, that is, the handle 200 can also be rotated and retracted upward, and the handle 200 can be expanded toward the outside of the grounding pin body 100 until it abuts against the connection groove, while maintaining a horizontally expanded state.
[0036] In some optional solutions, metal sleeves can be fixedly welded on both sides of the grounding pin body 100, one end of the handle 200 can be movably inserted into the metal sleeve, and a locking pin is radially inserted into the metal sleeve and the handle 200 for positioning, so that the handle 200 can be detachably connected for easy storage. The metal sleeve is conducive to enhancing the structural strength.
[0037] In some optional solutions, metal nuts can be fixedly welded on both sides of the grounding pin body 100, and the front end of the handle 200 can be threadedly connected to the metal nuts, and can also be easily disassembled and assembled.
[0038] In this embodiment, the grounding pin body 100 is set to an improved elliptical shape and the lever arm principle of the foldable handle 200 effectively solves the three major problems of difficult insertion, difficult removal, and easy injury to the hand, and has low manufacturing cost, simplicity and practicality.
[0039] In specific applications, the surface of the handle 200 can be provided with anti-skid patterns for easy holding. The handle 200 can be made of a suitable material such as threaded steel. The outside of the handle 200 can be covered with a rubber sleeve, and the outside of the rubber sleeve can be provided with anti-skid patterns.
[0040] In the embodiment of the present invention, the manual plug-in grounding pin of the distribution network can realize easy hole expansion of the grounding pin without damage by utilizing a unique elliptical structure design and a simple foldable handle 200, solving the problem of difficult insertion and removal of the grounding pin and easy injury to the hand. The elliptical design does not affect the grounding contact surface, fully meeting the electrical grounding requirements, and the foldable handle 200 is usually folded in line with the grounding pin for easy storage, which is more convenient and practical when a sledgehammer is not brought to some construction sites. The foldable handle 200 can be fixed to the grounding pin body 100 by a strap or a cable tie. In specific applications, a Velcro cable tie can be used to fix the foldable handle 200 to prevent the handle 200 from accidentally unfolding when the grounding pin is transported or stored.
[0041] Specifically, the manual plug-in type grounding pin of the distribution network is provided with a clamp, and the clamp has two side openings of the shrinking slots, and the two shrinking slots are used for the handle 200 after the clamp is folded to prevent the handle 200 from accidentally unfolding.
[0042] Specifically, the rear end of the grounding pin body 100 can be optionally provided with a hard alloy cover, which can be made of high-hardness alloy steel, which is sleeved on the rear end of the grounding pin body 100, and the sledgehammer acts on the hard alloy cover to avoid damage to the end of the grounding pin body 100, which is conducive to ensuring the service life of the grounding pin body 100. The outer side of the hard alloy cover can be spherical crown or arc surface, and the bottom has an opening to be sleeved on the rear end of the grounding pin body 100.
[0043] Specifically, the manual plug-in type grounding pin further includes two extension sleeves that can be movably sleeved on the handle 200, and the inner diameter of the extension sleeve can be larger than the outer diameter of the handle 200. After the grounding pin is inserted into the ground, if the soil is hard, it is relatively difficult to directly rotate the grounding pin in situ. By providing the extension sleeve and sleeve the extension sleeve on the handle 200, and then rotating the grounding pin body 100 in situ through the extension sleeve, the lever arm is longer and the torque generated is larger, which is conducive to rotating the grounding pin body 100.
[0044] Specifically, the length of the grounding pin body 100 may be in a suitable range of 75 to 120 cm, and the diameter of the handle 200 may be 5 mm to 12 mm. The length of the handle 200 may be 15 to 30 cm.
[0045] Specifically, the cross section of the grounding pin body 100 is elliptical, and the ratio of the secondary axis to the primary axis can be 0.5 to 0.85. The smaller the ratio, the flatter the grounding pin body 100. In a specific application, the ratio of the secondary axis to the primary axis can be 0.8, that is, when the primary axis size of the cross section of the grounding pin body 100 is 2 cm, the secondary axis size is 1.6 cm. The ratio of the secondary axis to the primary axis can be 0.6, that is, when the primary axis size of the cross section of the grounding pin body 100 is 2 cm, the secondary axis size is 1.2 cm. In a specific application, the primary axis size can be 1.5 to 3.0 cm, for example, 1.9 cm. When the voltage is higher, the outer diameter of the grounding pin body 100 is larger, and the primary axis size of the grounding pin can also be set to a suitable range.
[0046] In this embodiment, the length of the grounding pin body 100 is 80 to 90 cm, and the diameter of the handle 200 is 5 to 10 mm.
[0047] Specifically, the distance between the handle 200 and the rear end of the grounding pin body 100 is 15 to 25 cm.
[0048] In a specific application, the grounding pin body 100 is also fixedly provided with a wiring portion for connecting a ground wire.
[0049] Embodiment 2:
[0050] The present invention also provides an operation method of a distribution network manual plug-in type grounding pin, using a distribution network manual plug-in type grounding pin. Figure 1 and Figure 2As shown, the manual plug-in type grounding pin for distribution network includes a grounding pin body 100, the cross-section of the grounding pin body 100 is elliptical, and the front end of the grounding pin body 100 is conical, and the rear end of the grounding pin body 100 is provided with an auxiliary structure, which can be a handheld handle 200, so that the operator can support the manual plug-in type grounding pin for distribution network, so as to hammer the grounding pin body 100 into the ground to a set depth through an impact device such as a hammer, and the elliptical grounding pin is easier to knock in than the round one. After the grounding pin is inserted into the ground, when the grounding pin needs to be pulled out, the grounding pin body 100 can be twisted in place. Since the cross-section of the grounding pin body 100 is elliptical, the grounding pin is easier to knock in than when it is round. Its major axis (horizontal axis) is longer than the minor axis (longitudinal axis), and the grounding pin hole position will inevitably form an expanded hole, making it easy to pull out the grounding pin body 100. The operation process is simple, labor-saving and safe. In specific applications, the cross-section of the grounding pin body 100 may also be an elliptical shape. Such equivalent replacement also falls within the scope of protection of the present invention.
