Description

Technical Field

[0001] This utility model relates to the technical field of short-circuit grounding devices, specifically a portable short-circuit grounding device. Background Technology

[0002] Existing disconnect grounding wires have several defects and shortcomings in use. First, their structural design is mostly one-piece molding, making it difficult to precisely adjust the clamping force when holding the conductor, easily leading to insecure clamping and safety hazards. Even when clamping is possible, the lack of stable structures such as threaded self-locking means that in practical applications, they are prone to loosening and falling off under external force or after prolonged use, failing to reliably guarantee grounding effectiveness. Second, operational safety is poor. Operators must manually control the clamp frame to approach the conductor, making it easy for the human body to approach or even pass through the hanging area, greatly increasing the risk of electric shock. Third, maintenance is difficult. When damage or decreased insulation performance occurs, it is difficult to replace individual damaged internal structures; often, the entire unit needs to be replaced, which is not only costly but also affects the progress of power work during the replacement process.

[0003] The purpose of this invention is to provide a portable short-circuit grounding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable short-circuit grounding device, including a handle, a clamping mechanism at the top of the handle, and a rotating mechanism at the bottom of the clamping mechanism.

[0005] The clamping mechanism includes a clamping component, an adjusting component, a transmission component, and a fixing component. The clamping component is located at the top of the grip, the adjusting component is located inside the clamping component, the transmission component is located at the bottom of the adjusting component, and the fixing component is located at the bottom of the grip.

[0006] The rotating mechanism includes a rotating component and a locking component. The rotating component is located at the bottom of the transmission component, and the locking component is located inside the rotating component.

[0007] Preferably, the clamping assembly includes an L-shaped frame plate, which is fixedly connected to the top of the gripping rod. A clamping frame is fixedly connected to the rear side of the L-shaped frame plate. A clamping plate is provided inside the clamping frame. A movable slider is fixedly connected to the right side of the clamping plate. The movable slider is slidably connected to the right side of the clamping frame. A limiting piece is fixedly connected to the right side of the movable slider.

[0008] Preferably, the adjusting assembly includes a threaded rod, which is fixedly connected to the front side of the clamping plate. A threaded rotating cylinder is threadedly connected to the outer ring of the threaded rod. The threaded rotating cylinder is rotatably connected to the inner front side of the clamping frame and to the inner rear side of the L-shaped frame plate. A first bevel gear is fixedly connected to the front side of the outer ring of the threaded rotating cylinder. A second bevel gear meshes with the bottom of the outer ring of the first bevel gear. A rotating shaft is fixedly connected to the bottom of the second bevel gear. The rotating shaft is rotatably connected to the bottom of the L-shaped frame plate. A rotating block is fixedly connected to the bottom of the rotating shaft and rotatably connected to the top of the inner grip.

[0009] Preferably, the transmission assembly includes an insulating core rod disposed inside the grip rod. A locking block is fixedly connected to the top of the insulating core rod, and the locking block is engaged with the bottom of the rotating block.

[0011] Preferably, the rotating assembly includes a fixed rod, which is fixedly connected to the bottom of the insulating core rod, and a throttle is sleeved on the outer ring of the fixed rod.

[0012] Preferably, the locking assembly includes a bolt, which is snapped into the fixing rod and the throttle, and the outer ring of the bolt is threaded with a fixing screw, which is fixedly connected to the inner rear side of the throttle.

[0013] Compared with the prior art, the present invention provides a portable short-circuit grounding device, which has the following advantages:

[0014] 1. Compared with the traditional one-piece molded knife switch grounding wire, this portable short-circuit grounding device drives the rotation of bevel gear two through the interlocking transmission of the internal insulating core rod and the locking block of the handle. The transmission of bevel gear two and bevel gear one drives the threaded drum to rotate accordingly, thereby controlling the movement of the clamping plate to achieve the effect of clamping and fixing the exposed wire. Through the transmission between bevel gear two and bevel gear one, and the thread self-locking between the threaded rod and the threaded drum, the stability of the clamping plate and the clamping frame after clamping the wire is increased.

[0015] 2. This portable short-circuit grounding device controls the movement of the clamp plate by rotating the insulating core rod, eliminating the need for workers to manually control the clamp frame. The extended grip rod and insulating core rod increase the distance between the worker and the conductor, preventing the human body from passing through the hanging part and increasing the safety of the device during use.

[0016] 3. This portable short-circuit grounding device allows operators to lock the fixing rod and the handle simply by rotating the bolt. When using the device, one hand holds the rod in place while the other hand rotates the handle to control the rotation of the insulating core rod. This facilitates the operator's control over the clamping plate's position and makes the device easy to operate and use.

[0017] 4. This portable short-circuit grounding device can be disassembled and assembled by workers simply by rotating the bolts and external threaded rings and moving the various components. This allows workers to directly replace damaged internal structures during use, preventing the insulation effect of some insulation structures from decreasing due to prolonged use and ensuring that the device remains safe even after long-term use.

[0032] Example 1

[0033] Combination Figures 1 to 6 A portable short-circuit grounding device includes a handle 3, a clamping mechanism 1 at the top of the handle 3, and a rotating mechanism 2 at the bottom of the clamping mechanism 1.

[0034] The clamping mechanism 1 includes a clamping component 11, an adjusting component 12, a transmission component 13, and a fixing component 14. The clamping component 11 is located at the top of the grip 3, the adjusting component 12 is located inside the clamping component 11, the transmission component 13 is located at the bottom of the adjusting component 12, and the fixing component 14 is located at the bottom of the grip 3.

[0035] The clamping assembly 11 includes an L-shaped frame plate 1101, which is fixedly connected to the top of the gripping rod 3. A clamping frame 1102 is fixedly connected to the rear side of the L-shaped frame plate 1101. A clamping plate 1103 is disposed inside the clamping frame 1102. A movable slider 1104 is fixedly connected to the right side of the clamping plate 1103. The movable slider 1104 is slidably connected to the right side of the clamping frame 1102. A limit piece 1105 is fixedly connected to the right side of the movable slider 1104. The adjusting assembly 12 includes a threaded rod 1201, which is fixedly connected to... On the front side of clamping plate 1103, a threaded cylinder 1202 is threadedly connected to the outer ring of threaded rod 1201. The threaded cylinder 1202 is rotatably connected to the inner front side of clamping frame 1102 and the inner rear side of L-shaped frame plate 1101. A bevel gear 1203 is fixedly connected to the front side of the outer ring of threaded cylinder 1202. A bevel gear 2 1204 meshes with the bottom of the outer ring of bevel gear 1203. A rotating shaft 1205 is fixedly connected to the bottom of bevel gear 2 1204 and rotatably connected to the bottom of L-shaped frame plate 1101. Inside the unit, a rotating block 1206 is fixedly connected to the bottom of the rotating shaft 1205. The rotating block 1206 is rotatably connected to the top of the grip 3. The transmission assembly 13 includes an insulating core rod 1301, which is disposed inside the grip 3. A locking block 1302 is fixedly connected to the top of the insulating core rod 1301 and engages with the bottom of the rotating block 1206. A positioning sleeve 1303 is sleeved on the outer ring of the insulating core rod 1301 and is rotatably connected to the bottom of the inner ring of the grip 3. A positioning block is provided on the top of the positioning sleeve 1303. 1304, the positioning block 1304 is fixedly connected to the left and right sides of the insulating core rod 1301, the positioning sleeve 1303 is fixedly connected to the left and right sides of the locking pin 1305, the locking pin 1305 is engaged in the bottom of the grip rod 3, the fixing component 14 includes a threaded cover 1401, the threaded cover 1401 is sleeved on the bottom of the outer ring of the grip rod 3, the outer ring of the threaded cover 1401 is threadedly connected to an external threaded ring 1402, the external threaded ring 1402 is sleeved on the bottom end of the threaded cover 1401, and the bottom of the inner part of the external threaded ring 1402 is in contact with the bottom of the positioning sleeve 1303.

[0036] Furthermore, during use, the movement of the clamping plate 1103 is controlled by rotating the insulating core rod 1301, eliminating the need for workers to manually control the clamping frame 1102. The extended gripping rod 3 and the insulating core rod 1301 increase the distance between the worker and the wire, preventing the human body from passing through the hanging device and increasing the safety of the device during use.

[0037] Example 2

[0038] See Figure 1 , Figure 2 , Figure 5 and Figure 7 Furthermore, based on Embodiment 1, the rotating mechanism 2 includes a rotating component 21 and a locking component 22. The rotating component 21 is disposed at the bottom of the transmission component 13, and the locking component 22 is disposed inside the rotating component 21.

[0039] The rotating assembly 21 includes a fixed rod 2101, which is fixedly connected to the bottom of the insulating core rod 1301. The outer ring of the fixed rod 2101 is sleeved with a throttle 2102. The locking assembly 22 includes a bolt 2201, which is snapped into the fixed rod 2101 and the throttle 2102. The outer ring of the bolt 2201 is threadedly connected to a fixing screw 2202, which is fixedly connected to the inner rear side of the throttle 2102. The outer ring of the fixing screw 2202 is fixedly connected to a reinforcing fin 2203, which is fixedly connected to the inner rear side of the throttle 2102.

[0040] Furthermore, workers only need to rotate bolt 2201 and external threaded ring 1402, and move the various components to complete the overall disassembly and assembly of the device. This allows workers to directly replace damaged internal structures during use, preventing the insulation effect of some insulation structures from decreasing due to prolonged use, and ensuring that the device remains safe even after long-term use.

[0041] In actual operation, when this device needs to be assembled, the operator first inserts the insulating core rod 1301 into the handle 3, so that the locking block 1302 engages with the bottom of the rotating block 1206. Then, the operator moves the positioning sleeve 1303 upwards, so that the positioning sleeve 1303 engages with the bottom of the handle 3, until the top of the positioning sleeve 1303 is in contact with the bottom of the positioning block 1304. At this point, the initial positioning of the insulating core rod 1301 is completed, and the insulating core rod 1301 is positioned... The connection with the rotating block 1206 can be maintained by the locking block 1302. Then, the operator moves the external threaded ring 1402 upward and rotates it. The external threaded ring 1402 rotates and moves upward around the outer ring of the threaded cover 1401. The external threaded ring 1402 moves upward and fits onto the bottom end of the threaded cover 1401, so that the bottom of the external threaded ring 1402 fits against the bottom of the positioning sleeve 1303, thus fixing the position of the positioning sleeve 1303 and ensuring the stability of the subsequent connection between the locking block 1302 and the threaded rotating cylinder 1202.

[0042] Then, the worker will fit the handle 2102 onto the outer ring of the fixing rod 2101, aligning the holes inside the fixing rod 2101 and the handle 2102. The worker will then insert the bolt 2201 into the fixing rod 2101 and the handle 2102, and then rotate the bolt 2201. The bolt 2201 will rotate and move backward within the inner ring of the fixing screw 2202 until the bolt 2201 can no longer rotate. At this point, the locking process of the fixing rod 2101 and the handle 2102 is completed, and the overall installation of the device is completed.

[0043] When this device is needed to clamp exposed wires, the operator holds the handle 3 and the rotary handle 2102 with both hands respectively. Then, the clamping frame 1102 and clamping plate 1103 are moved to fit over the wires on both sides. The operator then rotates the rotary handle 2102. The rotation of the rotary handle 2102, through the bolt 2201, drives the fixed rod 2101 to rotate. The rotation of the fixed rod 2101 drives the insulating core rod 1301 to rotate. The rotation of the insulating core rod 1301, through the locking block 1302, drives the rotating block 1206 to rotate. 06 The rotation drives the second bevel gear 1204 to rotate via the rotating shaft 1205. The rotation of the second bevel gear 1204 drives the threaded drum 1202 to rotate via the first bevel gear 1203. The rotation of the threaded drum 1202 controls the threaded rod 1201 to move backward. The backward movement of the threaded rod 1201 drives the clamping plate 1103 to move backward. The backward movement of the clamping plate 1103 cooperates with the clamping frame 1102 to complete the clamping of the wire until the fixing rod 2101 can no longer rotate. At this point, the clamping of the exposed wire is completed.
