Description

Technical Field

[0001] The utility model relates to the technical field of grounding wire connection of power distribution equipment, in particular to a grounding wire connection device of power distribution equipment with a protection function. Background Art

[0002] The grounding wire is the "lifeline" of power engineering personnel. The hanging grounding wire is a safety barrier to protect maintenance personnel and can prevent sudden power outages from causing harm to the human body. The hanging grounding wire is an important electrical safety technical measure. High and low voltage grounding wires are used in line and substation construction to prevent static induction electric shock or accidental closing of nearby charged bodies to ensure safety.

[0003] For example, a grounding wire connection device with a protective function disclosed in Chinese patent CN215681195U is provided with a double-sided rack and a gear, which facilitates the gears on both sides of the double-sided rack to rotate in opposite directions by controlling the sliding of the double-sided rack, and further enables the clamping plate on one side of the gear to clamp the wire; the tension spring is provided so that after the pull ring is loosened, the double-sided rack can slide under the restoring force of the tension spring and drive the clamping plate to clamp the wire; the grounding component is provided to facilitate connecting the clamping plate to the ground.

[0004] Although this structure can clamp the wires, the size of the wires clamped by the device is relatively fixed, and the grounding effect of some thicker wires is not good. Therefore, we propose a grounding wire wiring device for distribution equipment with protection function that can clamp wires of different sizes so that the grounding work is not restricted, thereby improving the grounding work and making it more flexible. Utility Model Content

[0007] Preferably, the clamping assembly includes a double-sided rack slidably arranged inside the box body, the outer wall of the double-sided rack is meshed with a gear, a clamping plate is fixedly installed on the outer wall of the gear, a semicircular plate is fixedly installed on the end of the clamping plate away from the gear, a sliding bar is slidably arranged inside the semicircular plate, a first arc plate is fixedly installed on the end of the sliding bar, a first spring is sleeved on the outer wall of the sliding bar, an anti-sliding block is fixedly installed on the inner wall of the first arc plate, and a second arc plate is slidably arranged on the outer wall of the first arc plate.

[0008] Preferably, the locking assembly includes a slot opened on the outer wall of the double-sided rack, a fixed block is fixedly installed on the outer wall of the box body, a sliding rod is slidably arranged inside the fixed block, a locking pin is fixedly installed on the end of the sliding rod, and a second spring is sleeved on the outer wall of the sliding rod.

[0009] Preferably, there are two second arc plates, which are symmetrically distributed about the center line of the first arc plate. The second arc plates are slidably arranged with respect to the outer wall of the first arc plate. Under their restriction, the staggered first arc plates and second arc plates can clamp thinner wires for grounding.

[0010] Preferably, there are several anti-sliding blocks, which are equidistantly distributed on the inner walls of the first arc plate and the second arc plate, so that when the first arc plate and the second arc plate clamp the wire, the anti-sliding blocks can clamp the wire more firmly.

[0011] Preferably, the sliding rod fixedly installed inside the pin is slidably arranged inside the fixed block fixedly installed on the outer wall of the box body, and the outer wall of the pin is slidably arranged with the outer wall of the box body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The grounding wire wiring device of the power distribution equipment with protection function is composed of a clamping assembly as one of its components. When it is necessary to ground the wire, the grounding mechanism is inserted into the ground. At this time, the auxiliary handle is held to push the double-sided rack toward the inside of the box body. The double-sided rack squeezes the tension spring inside the box body, and the outer wall of the double-sided rack meshes with the outer wall of the gear. At this time, the two gears rotate, causing the clamping plate fixedly installed on the outer wall of the gear to rotate accordingly, and the semicircular plates fixedly installed at the ends of the two clamping plates move in opposite directions and are in an open state. When the semicircular plates are set on the outer wall of the wire, the double-sided rack is released at this time, and the tension spring inside the box body is not restricted by external force. Under the action of its elasticity, the double-sided rack is pushed toward the outside of the box body, causing the double-sided rack to mesh with the gear to rotate, and the gear drives the semicircular plates fixedly installed at the ends of the clamping plates to move in opposite directions, and the inside of the semicircular plates The first arc plate clamps the wire for grounding. When the wire is thicker, the outer wall of the wire contacts and squeezes the outer walls of the first arc plate and the second arc plate, causing the first arc plate and the second arc plate to expand. The sliding strips fixedly installed on the outer walls of the first arc plate and the second arc plate slide inside the semicircular plate, and the first spring sleeved on the outer wall of the sliding strip is squeezed. Under the action of the elasticity of the first spring, the first arc plate and the second arc plate are pushed toward each other to clamp the wire, which is convenient for clamping and grounding the thicker wire. When encountering thinner wires, the first arc plate slides on the inside of the second arc plate, and clamps the thinner wire under the push of the first spring. This structure can clamp wires of different sizes to improve the flexibility of grounding work (the box body, auxiliary handle and grounding mechanism are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0015] 2. The grounding wire wiring device of the power distribution equipment with a protective function is composed of a locking assembly as one of its components. When the wire is grounded, the pin is pulled first so that it is no longer engaged with the slot provided on the outer wall of the double-sided rack. At this time, the double-sided rack is pushed toward the inside of the box body. When the double-sided rack is released, the double-sided rack is pushed toward the outside of the box body under the restriction of the tension spring inside the box body, so that the outer wall of the double-sided rack and the end of the pin slide. When the pin is horizontal with the slot, the pin is pushed toward the inside of the slot under the action of the second spring elasticity, so that the pin is engaged with the slot to ensure a more stable clamping of the wire.

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] The utility model provides a grounding wire connection device for power distribution equipment with a protection function. Figures 1 to 6 As shown: a grounding wire connection device for power distribution equipment with a protective function, comprising a box body 1;

[0026] An auxiliary handle 2 is fixedly mounted on the outer wall of the box body 1;

[0027] A grounding mechanism 3 is provided on one side of the box body 1 away from the auxiliary handle 2;

[0028] And a processing component 4 is arranged outside the auxiliary handle 2, the processing component 4 includes a clamping component 41 arranged inside the box body 1, the clamping component 41 includes a double-sided rack 411 slidably arranged inside the box body 1, the outer wall of the double-sided rack 411 is meshed with a gear 412, the outer wall of the gear 412 is fixedly installed with a clamping plate 413, the end of the clamping plate 413 away from the gear 412 is fixedly installed with a semicircular plate 419, a slide bar 414 is slidably arranged inside the semicircular plate 419, a first arc plate 415 is fixedly installed at the end of the slide bar 414, the outer wall of the slide bar 414 is sleeved with a first spring 417, the inner wall of the first arc plate 415 is fixedly installed with an anti-sliding block 418, and the outer wall of the first arc plate 415 is slidably arranged with a second arc plate 416.

[0029] When the grounding of the wire is required, the grounding mechanism 3 is inserted into the ground. At this time, the auxiliary handle 2 is held to push the double-sided rack 411 toward the inside of the box body 1. The double-sided rack 411 squeezes the tension spring inside the box body 1, and the outer wall of the double-sided rack 411 meshes with the outer wall of the gear 412. At this time, the two gears 412 rotate, causing the clamping plate 413 fixedly installed on the outer wall of the gear 412 to rotate accordingly, and the semicircular plates 419 fixedly installed at the ends of the two clamping plates 413 move in opposite directions and are in an open state. When the semicircular plates 419 are set on the outer wall of the wire, the double-sided rack 411 is released at this time, and the tension spring inside the box body 1 is not restricted by external force. Under its elastic action, the double-sided rack 411 is pushed toward the outside of the box body 1, so that the double-sided rack 411 meshes with the gear 412 to rotate, and the gear 412 drives the semicircular plate 419 fixedly installed at the end of the clamping plate 413 to move in the opposite direction, and the first arc plate 415 inside the semicircular plate 419 meshes with the wire The first arc plate 415 and the second arc plate 416 are clamped to perform grounding work. When the size of the wire is thicker, the outer wall of the wire contacts and squeezes the outer wall of the first arc plate 415 and the second arc plate 416, so that the first arc plate 415 and the second arc plate 416 expand, and the sliding bar 414 fixedly installed on the outer wall of the first arc plate 415 and the second arc plate 416 slides inside the semicircular plate 419, and the first spring 417 sleeved on the outer wall of the sliding bar 414 is squeezed. Under the elastic action of the first spring 417, the first arc plate 415 and the second arc plate 416 are pushed towards each other to clamp the wire, which is convenient for clamping and grounding the thicker wire. When encountering a thinner wire, the first arc plate 415 slides on the inner side of the second arc plate 416, and under the push of the first spring 417, the thinner wire is clamped. This structure can clamp wires of different sizes to improve the flexibility of grounding work (the box body 1, the auxiliary handle 2 and the grounding mechanism 3 are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0030] Furthermore, there are two second arc plates 416, which are symmetrically distributed about the center line of the first arc plate 415. The second arc plates 416 are slidably arranged on the outer wall of the first arc plate 415. Under their restrictions, the staggered first arc plates 415 and second arc plates 416 can clamp thinner wires for grounding.

[0031] Furthermore, there are several anti-sliding blocks 418 equidistantly distributed on the inner walls of the first arc plate 415 and the second arc plate 416 , so that when the first arc plate 415 and the second arc plate 416 clamp the wires, the anti-sliding blocks 418 can clamp the wires more firmly.

[0032] Example 2

[0033] On the basis of Example 1, a preferred embodiment of a grounding wire connection device for power distribution equipment with a protection function provided by the utility model is as follows: Figures 1 to 6As shown: the locking assembly 42 includes a slot 421 opened on the outer wall of the double-sided rack 411, a fixing block 422 is fixedly installed on the outer wall of the box body 1, a slide bar 423 is slidably arranged inside the fixing block 422, a locking pin 425 is fixedly installed at the end of the slide bar 423, and a second spring 424 is sleeved on the outer wall of the slide bar 423.

[0034] In this embodiment, when the wire is grounded, the latch 425 is first pulled so that it is no longer engaged with the slot 421 provided on the outer wall of the double-sided rack 411. At this time, the double-sided rack 411 is pushed toward the inside of the box body 1. When the double-sided rack 411 is released, the double-sided rack 411 is pushed toward the outside of the box body 1 under the restriction of the tension spring inside the box body 1, so that the outer wall of the double-sided rack 411 and the end of the latch 425 slide. When the latch 425 is level with the slot 421, the latch 425 is pushed toward the inside of the slot 421 under the elastic action of the second spring 424, so that the latch 425 is engaged with the slot 421, so as to ensure a more stable clamping of the wire.

[0035] Furthermore, the slide bar 423 fixedly installed inside the latch 425 is slidably arranged inside the fixed block 422 fixedly installed on the outer wall of the box body 1, and the outer wall of the latch 425 is slidably arranged with the outer wall of the box body 1. Under its restriction, when the latch 425 is not subjected to tension, under the elastic action of the second spring 424, the latch 425 is pushed toward the direction of the double-sided rack 411 and is engaged with the slot 421 opened on the outer wall of the double-sided rack 411.

[0036] In addition, the outer wall of the fixing block 422 and the interior of the bayonet 425 are slidably arranged, and the end of the bayonet 425 is arranged in an inclined surface. Through the inclined surface of the end of the bayonet 425, the bayonet 425 can be conveniently engaged with the slot 421.

Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
