Description

Technical Field

[0001] The utility model relates to the technical field of power system connection tools, in particular to an electric auxiliary operation type grounding rod. Background Art

[0002] Power maintenance is a planned or accident emergency repair work for a single device or multiple interval devices in the power industry. In order to prevent the sudden power supply or induced electricity on the live side from causing harm to the maintenance personnel, the equipment to be repaired needs to be shut down and reliably grounded. At this time, a grounding rod is needed. When the common grounding rod is used, the staff first needs to climb the pole, then hang the grounding wire with a working rope, and then hang the grounding rod on the line. Then the operator needs to manually rotate the grounding rod and push the clamping mouth upward through the spiral piston rod until the clamp bites and fixes the wire. After the maintenance is completed, the grounding rod needs to be removed by the opposite operation. During the operation, due to the heavy grounding rod, the high line and the small locking tongue of the grounding rod, it is difficult for the staff to see whether the locking tongue and the wire are clamped in place when lifting the grounding rod in mid-air, and repeated attempts are required. The higher the voltage level of the equipment, the more time-consuming and labor-intensive this process is, which takes up a lot of operating time, making the operator tired and greatly reducing the efficiency of power outage.

[0003] In order to solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN201921215239.5 is an electric adjustable grounding rod, including a grounding rod main rod, a grounding rod main rod, a handle and an operating head; a control switch is provided on the handle; a micro motor is provided in the grounding rod main rod, and the output end of the micro motor is connected to a lifting inner rod, and the end of the lifting inner rod away from the grounding rod main rod is connected to the operating head; the operating head includes a connecting seat movably connected to the lifting inner rod, the lifting inner rod passes through the connecting seat, and a lower clamping seat is fixed on one end of the lifting inner rod protruding from the connecting seat; an upper clamping seat in a hook shape is provided on the connecting seat, the upper clamping seat is arranged opposite to the lower clamping seat, and a clamping line port is formed between the upper clamping seat and the lower clamping seat, and the control switch includes a first rotation direction switch for controlling the lifting inner rod to rotate in a first direction, a second rotation direction switch for controlling the lifting inner rod to rotate in a second direction, and a stop switch; the first rotation direction switch, the second rotation direction switch and the stop switch are connected in parallel to the main control circuit of the electric adjustable grounding rod. The electric adjustable grounding rod provided by the utility model can realize the rapid tightening or loosening of the electric wire, replaces the operation of manually rotating and tightening the grounding rod, reduces the physical energy consumption of the staff on the pole tower, and improves the safety during the operation.

[0004] However, the above-mentioned prior art has the following technical problems: in the electric adjustable grounding rod, when installing the grounding rod on the electric wire, it is necessary to first press the first rotation direction switch and wait for the spiral tube to rise. When the wire clamping mouth is closed, the stop switch is manually pressed to complete the installation of the grounding rod. In the actual operation process, since the electric wire is high and the grounding rod is heavy, the operator needs to hold the grounding rod in the air with both hands to install the grounding rod on the electric wire. Because the wire clamping mouth is small, it is difficult for the operator to confirm whether the wire clamping mouth is closed during the installation of the grounding rod, and repeated attempts are required, which takes up a lot of operation time.

DETAILED DESCRIPTION

[0019] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0020] Please refer to Figure 1 to Figure 2 An electric auxiliary operation type grounding rod 10 includes a grounding rod main rod 20, a telescopic assembly 30, a control terminal 40 and a wire clamping assembly 50. The telescopic assembly 30 is telescopically installed inside the grounding rod main rod 20, and the telescopic end of the telescopic assembly 30 extends from the top of the grounding rod main rod 20. The telescopic assembly 30 is electrically connected to the control terminal 40 so that the telescopic end of the telescopic assembly 30 can be controlled to be telescopic through the control terminal 40. The wire clamping assembly 50 includes an upper wire clamping groove 51 and a lower wire clamping groove 52. The upper wire clamping groove 51 is in the shape of a fishhook, and the lower wire clamping groove 52 is a square body with a semicircular clamping groove on the top surface. The hook handle of the upper wire clamping groove 51 is installed at the top of the grounding rod main rod 20, and the lower wire clamping groove 52 is installed at the telescopic end of the telescopic assembly 30. On the upper wire clamping groove 51, the inner arc surface of the lower wire clamping groove 52 is directly opposite; the upper wire clamping groove 51 is located above the lower wire clamping groove 52, and a first pressure sensor 53 is provided on the inner arc surface of the upper wire clamping groove 51. The first pressure sensor 53 is electrically connected to the control terminal 40, and is used to transmit the pressure data generated by the first pressure sensor 53 due to the pressure applied to the wire by the lower wire clamping groove 52 rising to the control terminal 40; the control terminal 40 is also used to control the telescopic component 30 to stop extending when the pressure data transmitted by the first pressure sensor 53 is the same as the preset tightening pressure. In this way, the electric assisted operation type grounding rod can be clamped to the wire without repeated attempts by the operator, thereby saving operation time.

[0021] In this embodiment, a second pressure sensor 54 is provided at the bottom of the lower wire clamping groove 52, and the second pressure sensor 54 is electrically connected to the control terminal 40, and is used to transmit the pressure data generated by the second pressure sensor 54 due to the pressure applied to the top surface of the grounding rod main rod 20 by the lowering of the lower wire clamping groove 52 to the control terminal 40; the control terminal 40 is also used to control the telescopic assembly 30 to stop retracting when the pressure data transmitted by the second pressure sensor 54 is the same as the preset release pressure, so as to save operation time.

[0022] Please refer to Figure 3 to Figure 4Further, the telescopic assembly 30 includes a telescopic rod 31, a driving motor 33, a first bevel gear 34, a second bevel gear 35 and a transmission gear 36. The telescopic rod 31 is installed inside the grounding rod main rod 20 and the top of the telescopic rod 31 extends from the top of the grounding rod main rod 20. The lower clamping groove 52 is fixedly installed at the top of the telescopic rod 31. The driving motor 33 is fixedly installed inside the grounding rod main rod 20. The first bevel gear 34 is fixed on the driving end of the driving motor 33 so that the first bevel gear 34 and the driving end of the driving motor 33 are connected. The ends rotate synchronously, the first bevel gear 34 is meshed and connected with the transmission gear 36, the inner ring of the second bevel gear 35 is fixedly connected with the outer ring of the transmission gear 36, the second bevel gear 35 is meshed and connected with a plurality of gear grooves 32 of the same size opened along the length direction of the telescopic rod 31, and the drive motor 33 is electrically connected to the control terminal 40, so as to control the forward and reverse rotation of the drive motor 33 by the control terminal 40 to control the lifting and lowering of the telescopic rod 31, so that the lower wire clamping groove 52 and the upper wire clamping groove 51 are combined or separated, so as to achieve the purpose of tightening or loosening the wires.

[0023] Furthermore, the interior of the grounding rod main pole 20 is hollow, which is used to install the telescopic rod 31 and the driving assembly, and can reduce the weight of the electric assisted operation type grounding rod 10, making it easy to operate and carry; a connecting head 21 is provided at the top of the grounding rod main pole 20 for connecting to the grounding wire.

[0024] In this embodiment, magnets 55 are provided at the hook handle and hook tip of the upper wire clamping slot 51 and the top of the semicircular clamping slot of the lower wire clamping slot 52, so as to strengthen the connection between the upper wire clamping slot 51 and the lower wire clamping slot 52 through the magnet 55, thereby preventing the lower wire clamping slot 52 from separating from the upper wire clamping slot 51 due to loosening of the connection between the telescopic rod 31 and the lower wire clamping slot 52.

[0025] Furthermore, the control terminal 40 is located at the bottom of the grounding rod main pole 20. The control terminal 40 is provided with a locking button for extending the telescopic end of the telescopic assembly 30, a releasing button for retracting the telescopic end of the telescopic assembly 30, and a stop button for forcibly stopping the telescopic assembly 30. By pressing the locking button, the drive motor 33 rotates forward, driving the telescopic rod 31 to rise, thereby driving the lower wire groove 52 to combine with the upper wire groove 51; by pressing the releasing button, the drive motor 33 reverses, driving the telescopic rod 31 to descend, thereby driving the lower wire groove 52 to separate from the upper wire groove 51. The control terminal 40 is equipped with a battery for powering the control terminal 40 and the drive motor 33.

[0026] In this embodiment, a control circuit is installed in the drive motor 33. Figure 5As shown, where M is the drive motor 33, E is the power supply, TZK is the stop switch, JK is the locking button, KK is the release button, JBK is the locking holding relay, JBK1 is the locking holding contact, KBK is the release holding relay, KBK1 is the release holding contact, YL1 and YL2 are both normally closed contacts of the pressure sensor, and the working principle of the control loop is as follows:

[0027] 1. During the rising (locking) process of the telescopic rod 31, the locking button JK is pressed. After the circuit is turned on, the locking holding relay JBK is energized, and its normally open contact JBK1 is closed to maintain the locking circuit. When the lock tongue rises into place and the pressure on the first pressure sensor 53 reaches the preset tightening pressure, the normally closed contact YL1 is opened, the control circuit is disconnected, and the locking process ends.

[0028] 2. During the descending (relaxing) process of the telescopic rod 31, the release button KK is pressed. After the circuit is turned on, the release holding relay KBK is energized, and its normally open contact KBK1 is closed to maintain the release circuit. When the lock tongue descends into place and the pressure on the second pressure sensor 54 reaches the preset release pressure, the normally closed contact YL2 is opened, the control circuit is disconnected, and the release process ends.

[0029] Furthermore, no matter whether the telescopic rod 31 is rising or falling, the operator can manually press the stop switch TZK to interrupt the operation to prevent the telescopic rod 31 from failing to stop automatically due to a malfunction.

[0030] When inspecting and repairing equipment, after the operator completes the preliminary operation preparations, he first verifies that there is no voltage on the three-phase equipment, then connects the ground wire to the connector 21, and then hangs the upper wire trough 51 on the wires of the equipment to be inspected. Then the operator presses the locking button of the control terminal 40, and the telescopic rod 31 rises under the drive of the drive motor 33, driving the lower wire trough 52 to support the wires, and the first pressure sensor 53 is compressed by the wires and transmits the pressure data to the control terminal 40. When the pressure data is the same as the preset tightening pressure in the control terminal 40, the lower wire trough 52 and the upper wire trough 51 complete the locking of the wires, and the control terminal 40 controls the drive motor 33 to stop rotating, and the operation ends.

[0031] After the inspection is completed, the operator first presses the release button, and the drive motor 33 drives the telescopic rod 31 to descend, causing the lower wire trough 52 to descend. The second pressure sensor 54 is compressed by the top of the grounding rod main rod 20 and transmits the pressure data to the control terminal 40. When the pressure data is the same as the preset release pressure in the control terminal 40, the lower wire trough 52 completes the reset and releases the wire. The control terminal 40 controls the drive motor 33 to stop rotating. Finally, the operator removes the upper wire trough 51 from the wire and completes the subsequent work.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
