Technical Field
[0001] This utility model relates to the field of ground grounding technology, and in particular to a durable anti-static ground grounding connection device. Background Technology
[0002] Antistatic grounding connection devices are used to connect the ground to the grounding system in the electrical system to prevent the accumulation of static electricity, thereby protecting personnel, equipment and facilities from the hazards of electrostatic discharge. Its main function is to ensure that static electricity does not accumulate and to safely release it through the grounding system. A grounding rod is one type of connection device.
[0003] Traditionally, when electrical workers inspect and maintain electrical equipment, they install one end of a grounding rod on an electric wire to prevent electrostatic discharge hazards. The grounding wire is then connected and fixed to the grounding rod with screws to ensure a path for electrostatic discharge. However, in actual use, it has been found that while a groove is often installed on the inner side of the clamp to facilitate the installation and fixing of the grounding rod, making it difficult for the clamp to rotate when it is on the electric wire, the groove has limited capacity and cannot guarantee the stability of the clamp and the electric wire. As a result, the grounding rod may shift and sway during rotation, affecting its normal use and assembly. Utility Model Content
[0004] The technical problem this utility model aims to solve is that, in order to facilitate the installation and fixing of grounding rods, a groove is usually provided on the inner side of the rod clamp to prevent the rod clamp from rotating when it is attached to the wire, thus facilitating the operation and rotation of the grounding rod. However, the specifications of the groove are limited, making it difficult to ensure the stability of the rod clamp and the wire. As a result, the rod may shift and shake during rotation, affecting the normal use and assembly of the grounding rod.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a durable anti-static grounding connection device, including a grounding rod, a rod clamp provided on the surface of the grounding rod, wherein a wire groove is opened on the inner wall of the rod clamp, two screws are bolted to the surface of the rod clamp, a threaded rod is threadedly connected to the surface of the rod clamp, wherein an operating rod is fixedly connected to the other end of the threaded rod, and a pressure plate is rotatably provided at the other end of the threaded rod, wherein the pressure plate is slidably disposed with the inner wall of the rod clamp, and an auxiliary device is provided on the surface of the rod clamp, wherein the auxiliary device enhances the connection stability between the rod clamp and the wire with the aid of a limiting plate.
[0006] The effect achieved by the above components is as follows: when the power equipment is being inspected and maintained, the grounding wire is first installed on the surface of the clamp with screws, then the wire groove of the clamp is clamped on the surface of the wire, and the limiting device on the surface of the clamp will further limit the position of the wire. Then, the rotating operating bar is operated to make the threaded rod rotate on the inner wall of the clamp, which in turn drives the pressure plate to slide on the inner wall of the clamp until the pressure plate comes into contact with and squeezes the wire.
[0007] Preferably, the auxiliary device includes a mounting plate, wherein the mounting plate is fixedly connected to the surface of the rod clamp, and mounting rods are fixedly connected to both ends of the mounting plate, wherein limit plates are rotatably provided through both ends of the mounting rods, and torsion springs are respectively sleeved on the arc surfaces of both ends of the mounting rods. The two ends of the torsion springs are respectively connected and fixed to the mounting plate and the limit plates. Fixing plates are fixedly connected to both sides of the surface of the rod clamp, wherein first springs are installed on both sides of the inner wall of the fixing plates, and the other end of the first springs is fixedly connected to the surface of the limit plates.
[0008] The effect achieved by the above components is that when the grounding rod is in use, it can better ensure the stability between the wire and the rod clamp, thereby facilitating the connection, fixing and disassembly of the grounding rod and the wire, and further improving the convenience of using the grounding rod.
[0009] Preferably, the auxiliary device further includes a reinforcing plate installed on one side of the arc surface of the limiting plate, wherein the reinforcing plate enhances the stability of the limiting plate during use.
[0010] The effect achieved by the above components is that the rubber reinforcement plate makes the two limiting plates more stable when they come into contact with each other, thereby allowing the wire to be better covered on the surface of the wire and ensuring the normal use of the auxiliary device.
[0011] Preferably, the auxiliary device further includes a connecting rod, wherein the two ends of the connecting rod are respectively connected and fixed to the surfaces of two limiting plates on the same arc surface of the mounting rod.
[0012] The effect achieved by the above components is that, through the setting of the connecting rod, the limiting plates on the arc surfaces at both ends of the same mounting rod can rotate synchronously, thereby making the limiting operation of the wire more convenient and efficient.
[0013] Preferably, a rotating plate is fixedly connected to the surface of the limiting plate, wherein an auxiliary rope is fixedly connected to the surface of the rotating plate, the auxiliary rope is threaded through the surface of the fixed plate, and a baffle is fixedly connected to one end of the auxiliary rope, and a second spring is sleeved on the arc surface of the auxiliary rope.
[0014] The effect achieved by the above components is as follows: when the grounding rod is disassembled after the power construction is completed, the operating rod is rotated so that the threaded rod drives the pressure plate to break away from the contact and compression of the wire. Then, the auxiliary ropes on the surface of the two fixed plates are pulled. Through the pulling of the auxiliary ropes, the rotating plate drives the limiting plate to rotate on the arc surface of the mounting rod, so that the two mutually contacting limiting plates are separated, thereby facilitating the separation of the wire from the auxiliary device.

[0016] The effect achieved by the above components is that when the grounding rod is idle, the screw position of the rod clamp is less likely to come into contact with other foreign objects, water stains, etc., thereby preventing wear and corrosion of the screw and its assembly position, thus extending the service life of the grounding rod and improving its durability.
[0017] Preferably, the protective device further includes a connecting rope mounted on the surface of the bolt, wherein the other end of the connecting rope is connected and fixed to the surface of the rod clamp.
[0018] The effect achieved by the above components is that the connection rope makes the bolts easier and quicker to use, thus providing more convenient protection for the grounding wire connection position of the rod clamp.
[0019] Preferably, a positioning frame is fixedly connected to the surface of the protective cover, and a positioning plate is fixedly connected to the surface of the rod clamp, wherein the positioning plate and the inner wall of the positioning frame are interlocked.
[0020] The effect achieved by the above components is that, through the insertion of the positioning plate and the positioning frame, the protective cover can achieve a pre-fixed effect during assembly, thereby facilitating the installation and fixing of the protective cover with bolts.

[0031] Figure 1 and Figure 2 The durable anti-static grounding connection device shown includes a grounding rod 1, a rod clamp 2 on the surface of the grounding rod 1, a wire groove 6 on the inner wall of the rod clamp 2, two screws 9 connected to the surface of the rod clamp 2 by bolts 83, a threaded rod 3 threadedly connected to the surface of the rod clamp 2, an operating rod 4 fixedly connected to the other end of the threaded rod 3, and a pressure plate 5 rotatably connected to the other end of the threaded rod 3, wherein the pressure plate 5 is slidably disposed with the inner wall of the rod clamp 2, an auxiliary device 7 is provided on the surface of the rod clamp 2, wherein the auxiliary device 7 enhances the connection stability between the rod clamp 2 and the wire by means of a limiting plate 73, and a protective device 8 is provided on the surface of the rod clamp 2 at the screws 9.
[0032] Figure 1 , Figure 2 and Figure 3The auxiliary device 7 shown includes a mounting plate 71, which is fixedly connected to the surface of the rod clamp 2. Mounting rods 72 are fixedly connected to both ends of the mounting plate 71. Limiting plates 73 are rotatably mounted through both ends of the mounting rods 72, and torsion springs 74 are sleeved on the arc surfaces of both ends of the mounting rods 72. The two ends of the torsion springs 74 are fixedly connected to the mounting plate 71 and the limiting plates 73, respectively. Fixing plates 76 are fixedly connected to both sides of the surface of the rod clamp 2. First springs 75 are installed on both sides of the inner wall of the fixing plates 76, and the other end of the first springs 75 is fixedly connected to the surface of the limiting plates 73. During the maintenance of the electrical equipment, the grounding wire is first installed on the surface of the rod clamp 2 using screws 9. Then, the wire groove 6 of the rod clamp 2 is clamped onto the surface of the wire, and at this time, the wire will be connected to the two mounting rods 72. When the limiting plates 73 at the same end of the grounding rod 1 come into contact with each other, the wire is squeezed between the two limiting plates 73. At this time, the limiting plates 73 will rotate under the torsional force of the torsion spring 74 and the elastic force of the first spring 75, causing the limiting plates 73 to rotate on the arc surface of the mounting rod 72 fixedly connected to the mounting plate 71, so that the two limiting plates 73 are in stable contact with each other, which will further limit the position of the wire. Then, the rotating operating rod 4 is operated to rotate the threaded rod 3 on the inner wall of the rod clamp 2, which in turn drives the pressure plate 5 to slide on the inner wall of the rod clamp 2 until the pressure plate 5 comes into contact with the wire and squeezes it. At this time, when the grounding rod 1 is used, it can better ensure the stability between the wire and the rod clamp 2, thus facilitating the connection, fixation and disassembly of the grounding rod 1 and the wire, and further improving the convenience of using the grounding rod 1.
[0033] Figure 1 , Figure 2 and Figure 3 The auxiliary device 7 shown also includes a reinforcing plate 77 installed on one side of the arc surface of the limiting plate 73. The reinforcing plate 77 enhances the stability of the limiting plate 73. The rubber reinforcing plate 77 makes the two limiting plates 73 more stable when they come into contact with each other, so that the wire is better covered on the surface of the wire, ensuring the normal use of the auxiliary device 7. The auxiliary device 7 also includes a connecting rod 78. The two ends of the connecting rod 78 are respectively connected and fixed to the surfaces of the two limiting plates 73 on the arc surface of the same mounting rod 72. The connecting rod 78 allows the limiting plates 73 on the arc surfaces at both ends of the same mounting rod 72 to rotate synchronously, making the limiting operation of the wire more convenient and efficient.
[0034] Figure 1 , Figure 2 and Figure 3A rotating plate 79 is fixedly connected to the surface of the limiting plate 73 shown. An auxiliary rope 710 is fixedly connected to the surface of the rotating plate 79. The auxiliary rope 710 passes through the surface of the fixed plate 76, and a baffle 711 is fixedly connected to one end of the auxiliary rope 710. A second spring 712 is sleeved on the arc surface of the auxiliary rope 710. When the grounding rod 1 is disassembled after the power construction is completed, the operating rod 4 is rotated, so that the threaded rod 3 drives the pressure plate 5 to disengage from the contact and compression of the wire. Then, the auxiliary rope 710 on the surface of the two fixed plates 76 is pulled. Through the pulling of the auxiliary rope 710, the rotating plate 79 drives the limiting plate 73 to rotate on the arc surface of the mounting rod 72, so that the two mutually contacting limiting plates 73 are separated, thereby facilitating the disengagement of the wire from the auxiliary device 7.
[0035] Figure 1 , Figure 2 and Figure 4 The protective device 8 shown includes two mounting plates 81, which are fixedly connected to both sides of the surface of the rod clamp 2. The surface of the rod clamp 2 is covered by a protective cover 82 at the screw 9. The protective cover 82 is threadedly connected to the two mounting plates 81 by two bolts 83. When the grounding rod 1 is not in use, the protective cover 82 covers the screw 9 position of the rod clamp 2, and the protective cover 82 is in contact with the mounting plates 81 fixedly connected to both sides of the surface of the rod clamp 2. Then, the two bolts 83 are passed through both sides of the protective cover 82, and the bolts 83 are threadedly connected to the mounting plates 81, thereby fixing the position of the protective cover 82. At this time, when the grounding rod 1 is not in use, the screw 9 position of the rod clamp 2 is not easily in contact with other foreign objects, water stains, etc., so that the screw 9 and its mounting position are not easily worn or corroded, thereby extending the service life of the grounding rod 1 and improving its durability.
[0036] Figure 1 , Figure 2 and Figure 4 The protective device 8 shown also includes a connecting rope 84 installed on the surface of the bolt 83, wherein the other end of the connecting rope 84 is fixedly connected to the surface of the rod clamp 2. The connection rope 84 makes it more convenient and quick to use the bolt 83, thereby making it easier to protect the grounding wire connection position of the rod clamp 2. A positioning frame 86 is fixedly connected to the surface of the protective cover 82, and a positioning plate 85 is fixedly connected to the surface of the rod clamp 2. The positioning plate 85 and the inner wall of the positioning frame 86 are interlocked. Through the interlocking of the positioning plate 85 and the positioning frame 86, the protective cover 82 can achieve a pre-fixing effect during assembly, thereby facilitating the installation and fixation of the protective cover 82 by the bolt 83.
[0037] Working principle: During the inspection and maintenance of power equipment, the grounding wire is first installed on the surface of the clamp 2 using screws 9. Then, the wire groove 6 of the clamp 2 is clamped onto the surface of the wire. At this time, the wire will come into contact with the mutually abutting limiting plates 73 on the same end of the two mounting rods 72, thus squeezing the wire between the two limiting plates 73. At this time, the limiting plates 73 will rotate under the torsional force of the torsion spring 74 and the elastic force of the first spring 75, causing the limiting plates 73 to rotate on the arc surface of the mounting rods 72 fixedly connected to the mounting plate 71, thereby making the two limiting plates 73 in stable contact with each other, further limiting the position of the wire. Then, the rotating operating rod 4 is operated to make the threaded rod 3 rotate on the inner wall of the clamp 2, thereby driving the pressure plate 5 to slide on the inner wall of the clamp 2 until the pressure plate 5 comes into contact with and squeezes the wire. At this time, when the grounding rod 1 is used, it can better ensure the stability between the wire and the clamp 2, thus facilitating the connection, fixation and disassembly of the grounding rod 1 and the wire, further improving the convenience of using the grounding rod 1.
[0038] When the grounding rod 1 is not in use, the protective cover 82 is placed over the screw 9 of the rod clamp 2, and the protective cover 82 is made to contact the mounting plate 81 which is fixedly connected to both sides of the surface of the rod clamp 2. Then, two bolts 83 are passed through both sides of the protective cover 82, and the bolts 83 are threadedly connected to the mounting plate 81, thereby fixing the position of the protective cover 82. At this time, when the grounding rod is not in use, the screw 9 of the rod clamp 2 is not likely to come into contact with other foreign objects, water stains, etc., so that the screw 9 and its mounting position are not prone to wear and corrosion, thereby extending the service life of the grounding rod 1 and improving its durability.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
