Description

Technical Field

[0001] The invention relates to the technical field of grounding devices, and in particular to a grounding device at a construction site of an electric power system. Background Art

[0002] Grounding is an electricity safety measure taken to ensure the normal operation of electrical equipment and personal safety. It is achieved by connecting metal wires to grounding devices. Commonly used methods include protective grounding, working grounding, lightning protection grounding, shielding grounding, anti-static grounding, etc. During the construction of the power system, the wires of external equipment need to be grounded through grounding devices to facilitate operators to inspect and repair external equipment. Traditional grounding wire devices are more convenient to operate for horizontally arranged wires, but for vertically arranged wires, the grounding wire clamps are easily detached from the transmission cables under the action of gravity.

[0003] A Chinese patent with publication number CN114792895B discloses a grounding wire device, which is mainly used for grounding vertical conductors and can effectively avoid unstable and loose clamping of the conductors due to accidental contact.

[0004] However, in actual use, traditional grounding wire clamps are usually hung or clamped on transmission cables. At this time, due to the gravity of the grounding wire clamp, it may be easily affected by external influences and shake, which may easily make the contact between the grounding wire clamp and the transmission cable unstable, thereby reducing the grounding stability. At the same time, when installing the grounding wire clamp, it is generally clamped by rotating the insulating rod. When the grounding wire clamp is used for a vertical transmission cable, the distance between the insulating rod and the transmission cable is relatively close, which poses certain safety hazards.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0026] See also Figure 1 - Fig.10 An embodiment of the present invention provides a technical solution: a grounding device at a construction site of an electric power system, comprising a grounding rod 1 and a fixing seat 5 fixed to the upper end of the grounding rod 1. Preferably, an insulating layer is provided on the outer surface of the grounding rod 1 to prevent the user from getting an electric shock. The grounding assembly is also provided, and the grounding assembly is rotatably mounted on the fixing seat 5 for grounding a power transmission cable 12 in different directions. Preferably, an installation groove is provided at the connection between the fixing seat 5 and the grounding assembly to facilitate the installation and rotation of the grounding assembly.

[0027] The power system construction grounding device provided in this embodiment also includes a connecting nut 4, which can be lifted and installed on the outside of the grounding rod 1, and a connecting rod 10 is hinged on the outside of the connecting nut 4. The connecting rod 10 is a component made of insulating material, and the connecting rod 10 can be a self-locking telescopic rod to adjust the length of the connecting rod 10. In addition, an auxiliary clamp 11 is movably installed at the other end of the connecting rod 10 to assist in fixing the grounding assembly and the grounding rod 1.

[0028] It should be noted that by adjusting the height of the connecting nut 4, the auxiliary clamp 11 is wrapped and fixed on the outside of the transmission cable 12. At this time, a triangular structure is formed between the grounding component, the auxiliary clamp 11 and the connecting nut 4, thereby improving the stability of the grounding rod 1 and reducing the large shaking of the grounding rod 1 due to external factors, so as to improve the contact stability between the grounding component, the auxiliary clamp 11 and the transmission cable 12. When the transmission cable 12 is in a vertical direction, at this time, by manually controlling the angle between the connecting rod 10 and the grounding rod 1, the connecting rod 10 pushes the lower end of the grounding rod 1 to move away from the transmission cable 12. This can increase the torque between the auxiliary clamp 11, the grounding component and the transmission cable 12, thereby improving the contact effect of the auxiliary clamp 11, the grounding component and the transmission cable 12, and can also adjust the distance between the lower end of the grounding rod 1 and the transmission cable 12 to facilitate the staff to operate the grounding rod 1.

[0029] In order to improve the safety performance during the grounding process, the power system construction grounding device provided in this embodiment also includes a grounding wire 14, which is a "Y"-shaped structure. One end of the grounding wire 14 is electrically connected to the grounding component, and the other end of the grounding wire 14 is electrically connected to the auxiliary clamp 11. In addition, the remaining end of the "Y"-shaped grounding wire 14 is electrically connected to the grounding pole to achieve grounding of the transmission cable 12.

[0030] In this solution, the "Y"-shaped grounding wire 14 can ensure that the transmission cable 12 located at the auxiliary clamp 11 and the grounding component is grounded synchronously, thereby avoiding the auxiliary clamp 11 or the grounding component from detaching from the transmission cable 12, resulting in a decrease in grounding stability, and improving the safety performance of the transmission cable 12 when grounding.

[0031] like Figure 5 - Fig. 9 As shown, the grounding assembly provided in this embodiment includes a connecting base 6 rotatably mounted on a fixed base 5, and a grounding clamp 7 is symmetrically provided on one side of the connecting base 6. The two grounding clamps 7 form a trumpet-shaped structure. Through the setting of the trumpet-shaped structure, the transmission cable 12 is conveniently embedded in the inner side of the two grounding clamps 7, and a gap 33 is provided at the middle position of the two grounding clamps 7.

[0032] A lining strip 8 is fixed between the two grounding clamps 7 at the upper and lower surfaces of the gap 33, wherein a rotating shaft 18 is rotatably installed inside one of the gaps 33, a half gear 19 is fixedly sleeved on the rotating shaft 18, and a baffle strip 9 is provided on one side of the half gear 19. The baffle strip 9 is driven to move by the rotation of the half gear 19, thereby adjusting the range of the enclosed area between the baffle strip 9 and the lining strip 8 for fixing power transmission cables 12 of different specifications.

[0033] In order to improve the fixing effect of the transmission cable 12, the two lining strips 8 and the baffle strips 9 are offset up and down, and the gap 33 surrounded by the lining strips 8, the baffle strips 9 and the grounding clamp 7 is used to accommodate the transmission cable 12. Preferably, the surfaces of the lining strips 8 and the baffle strips 9 are provided with anti-slip grooves to improve the fixing effect of the transmission cable 12 after the connection. After the transmission cable 12 is connected, the half gear 19 rotates to drive the baffle strip 9 to move, so that one side of the baffle strip 9 is embedded in the inner side of the gap 33 on the opposite side to achieve an embracing fixation of the transmission cable 12. In the process, due to the offset setting of the lining strips 8 and the baffle strips 9, the transmission cable 12 located at the grounding clamp 7 can be slightly twisted, thereby increasing the connection effect between the transmission cable 12 and the lining strips 8 and the baffle strips 9, and improving the electrical connection and fixation stability between the grounding component and the transmission cable 12.

[0034] like Figure 1 - Figure 4As shown, in order to facilitate the connection between the auxiliary clamp 11 and the power transmission cable 12, the auxiliary clamp 11 provided in this embodiment is in a "U"-shaped structure, so that the power transmission cable 12 can be inserted into the auxiliary clamp 11, and an electrical liner 17 is fixed to the lower end of the auxiliary clamp 11, and arc-shaped spring pieces 15 are provided at equidistant positions on the inner wall of the auxiliary clamp 11, and anti-slip teeth 16 are provided on the outer sides of the arc-shaped spring pieces 15 facing the electrical liner 17. Preferably, fixing plates are detachably fixed on both sides of the inner wall of the auxiliary clamp 11, and the fixing plates are integrally formed with the arc-shaped spring pieces 15 on the same side, and the fixing plates and the auxiliary clamp 11 are preferably threadedly connected to facilitate replacement and maintenance of the arc-shaped spring pieces 15 when the elasticity is insufficient in the later stage.

[0035] In order to improve the stability of the connection between the auxiliary clamp 11 and the transmission cable 12, the arc-shaped spring piece 15 provided in this embodiment is an arc-shaped structure, and an "X"-shaped structure is formed between the arc-shaped spring pieces 15 on the opposite sides. The upper end of the arc-shaped spring piece 15 is fixed to the upper end of the inner wall of the auxiliary clamp 11, and the lower end of the arc-shaped spring piece 15 is movably connected to the auxiliary clamp 11. The arc-shaped spring pieces 15 on the two side surfaces of the auxiliary clamp 11 are staggered, and anti-slip teeth 16 are provided on the outer side of the arc-shaped spring piece 15 facing the bottom of the auxiliary clamp 11. In this scheme, the arc-shaped spring piece 15 has a certain locking effect through the staggered setting of the arc-shaped spring pieces 15 on the opposite sides, thereby preventing the transmission cable 12 from actively detaching from the auxiliary clamp 11, thereby improving the fixing effect of the auxiliary clamp 11 on the transmission cable 12.

[0036] In this embodiment, the "X"-shaped structure is provided to facilitate the insertion of the transmission cable 12 between the arc-shaped spring pieces 15 on both sides, and is also conducive to the detachment of the auxiliary clamp 11 from the transmission cable 12 in the later stage. When the transmission cable 12 is connected to the auxiliary clamp 11, an external force acts on the auxiliary clamp 11, so that the transmission cable 12 squeezes the arc-shaped spring piece 15, thereby reducing the curvature of the arc-shaped spring piece 15, that is, the lower end of the arc-shaped spring piece 15 extends toward the lower end of the auxiliary clamp 11, and further opens the gap between the relative arc-shaped spring pieces 15, so as to facilitate the installation between the transmission cable 12 and the auxiliary clamp 11. After the transmission cable 12 is installed, the arc-shaped spring piece 15 is restored by the elastic force. At this time, the arc-shaped spring piece 1 located at the anti-slip tooth 16 is 5 is pressed against the transmission cable 12 to improve the connection stability between the transmission cable 12 and the electrical liner 17. When the transmission cable 12 is detached from the auxiliary clamp 11, an external force acts on the auxiliary clamp 11. At this time, the transmission cable 12 squeezes the arc-shaped spring piece 15, so that the lower end of the arc-shaped spring piece 15 moves away from the bottom of the auxiliary clamp 11. Under the continuous action of the external force, the transmission cable 12 is embedded between the arc-shaped spring pieces 15 on both sides. At this time, the transmission cable 12 squeezes the arc-shaped spring piece 15, so that the curvature of the arc-shaped spring piece 15 becomes smaller, that is, the lower end of the arc-shaped spring piece 15 extends toward the lower end of the auxiliary clamp 11, and further the gap between the opposite arc-shaped spring pieces 15 is opened, so as to facilitate the separation of the transmission cable 12 from the auxiliary clamp 11.

[0037] exist Figure 5 - Fig. 9 As shown, in order to facilitate the driving of the half gear 19 to rotate, a driving shaft 23 is rotatably installed in the fixed seat 5, and a first worm 24 is provided at the driving shaft 23 located inside the connecting seat 6. A driven shaft 20 is rotatably installed inside the connecting seat 6, and a first worm wheel 21 meshing with the first worm 24 is provided on the driven shaft 20, and a driven gear 22 meshing with the half gear 19 is fixed on the outer side of the driven shaft 20 below the first worm wheel 21.

[0038] In the embodiment, the first worm 24 is driven to rotate by the driving shaft 23, and the driven shaft 20 is rotated under the meshing between the first worm 24 and the first worm wheel 21, and the driven shaft 20 further drives the driven gear 22 to rotate, and the meshing between the driven gear 22 and the half gear 19 makes the baffle 9 move inside the gap 33, so that the transmission cable 12 can be clamped between the lining strip 8, the baffle 9 and the grounding clamp 7. It should be noted that in the present scheme, the transmission action between the first worm 24 and the first worm wheel 21 has a certain self-locking effect, which can prevent the first worm wheel 21 from rotating in the opposite direction to drive the first worm 24, thereby preventing the baffle 9 from automatically opening, resulting in a decrease in the clamping effect of the transmission cable 12.

[0039] like Figure 5 - Fig.10 As shown, in order to facilitate the rotation of the connecting seat 6 to adjust the angle of the grounding clamp 7, thereby facilitating the grounding of the power transmission cable 12 in different directions, a transmission cavity 27 is opened in the fixed seat 5 on one side of the connecting seat 6, and shaft sleeves 25 rotatably connected to the fixed seat 5 are fixed on both sides of the connecting seat 6. The shaft sleeves 25 are sleeved on the outside of the driving shaft 23, and the shaft sleeves 25 are rotatably connected to the driving shaft 23.

[0040] In this solution, the sleeve 25 is preferably perpendicular to the grounding rod 1. By rotating the sleeve 25, the connecting seat 6 drives the grounding clamp 7 to rotate, thereby adjusting the angle of the grounding clamp 7, thereby facilitating the grounding of the transmission cable 12 in different directions.

[0041] like Figure 5 - Fig.10 As shown, in order to facilitate the rotation of the drive sleeve 25 so as to adjust the angle of the grounding clamp 7, one end of the sleeve 25 extends to the inside of the transmission chamber 27 and is installed with a second worm gear 32, and a second drive shaft 28 is rotatably installed inside the transmission chamber 27. A second worm 29 meshing with the second worm gear 32 is fixedly sleeved on the second drive shaft 28, and the other end of the second drive shaft 28 passes through the transmission chamber 27 and is installed with a knob.

[0042] In the present embodiment, the second drive shaft 28 is driven to rotate by the knob, and the second drive shaft 28 further drives the second worm 29 to rotate. Through the engagement between the second worm 29 and the second worm wheel 32, the second worm wheel 32 drives the sleeve 25 to rotate, and the angle of the grounding clamp 7 is further adjusted to adapt to the grounding of the power transmission cable 12 in different directions. It should be noted that in the present embodiment, since the engagement between the second worm 29 and the second worm wheel 32 has a self-locking effect, the second worm wheel 32 can be prevented from rotating in the opposite direction to drive the second worm 29 to rotate, thereby preventing the connecting seat 6 from actively rotating to drive the sleeve 25 to rotate, thereby improving the stability of the connecting seat 6 after the angle is adjusted, and preventing the fixing effect of the connecting seat 6 after the angle is adjusted due to the gravity of the equipment.

[0043] like Figure 5 - Fig.10 As shown, in order to facilitate the driving shaft 23 to rotate, one end of the driving shaft 23 in this embodiment extends to the inside of the transmission cavity 27 and is installed with a second bevel gear 31, and the first driving shaft 26 is rotatably installed inside the grounding rod 1. The upper end of the first driving shaft 26 extends to the inside of the transmission cavity 27 and is installed with a first bevel gear 30. The first bevel gear 30 is meshed with the second bevel gear 31, and the lower end of the first driving shaft 26 passes through the bottom of the grounding rod 1 and is installed with a turntable 13.

[0044] In this solution, the first drive shaft 26 is driven to rotate by rotating the turntable 13 , the first bevel gear 30 is rotated by the first drive shaft 26 , and the driving shaft 23 is rotated by the meshing between the first bevel gear 30 and the second bevel gear 31 .

[0045] like Figure 1 , Figure 2 and Fig.10 As shown, in order to facilitate the height adjustment of the connecting nut 4, a groove 2 is provided on the outer side of the grounding rod 1, and the groove 2 is mainly used to limit the range of movement of the connecting nut 4. A pipe thread 3 is provided on the surface of the groove 2, and the pipe thread 3 is threadedly connected to the connecting nut 4.

[0046] In this embodiment, the pipe thread 3 is threadedly connected to the connecting nut 4, so that the connecting nut 4 is raised and lowered inside the groove 2, thereby adjusting the height of the connecting nut 4. It should be noted that since the connecting nut 4 is threadedly connected to the groove 2, when the connecting nut 4 rotates one circle, the height lifting range of the connecting nut 4 is small. Therefore, when the height of the connecting nut 4 is adjusted, the rotation angle of the connecting nut 4 has little effect on the connecting rod 10. When the angle of the connecting rod 10 does not meet the standard, it is only necessary to slightly rotate the connecting nut 4.

[0047] like Figure 1 and Figure 2As shown, in order to facilitate the movement of the connecting rod 10 to drive the movement of the auxiliary clamp 11, a second articulated seat 35 is rotatably installed on the outside of the connecting nut 4, and the second articulated seat 35 is hinged to one end of the connecting rod 10. A first articulated seat 34 is fixed to the bottom of the auxiliary clamp 11, and the first articulated seat 34 is hinged to the other end of the connecting rod 10.

[0048] In this solution, the position angle of the auxiliary clamp 11 can be adjusted through the first articulated seat 34 and the second articulated seat 35, so as to facilitate the connection of the auxiliary clamp 11 with the power transmission cables 12 in different directions.

[0049] like Figure 1 - Figure 4 As shown, to facilitate the grounding of the transmission cable 12, one end of the grounding wire 14 is electrically connected to the lining strip 8, and the other end of the grounding wire 14 is electrically connected to the electrical lining platform 17 to ensure that the transmission cable 12 located at the auxiliary clamp 11 and the grounding component is grounded synchronously, thereby avoiding the auxiliary clamp 11 or the grounding component from detaching from the transmission cable 12, resulting in a decrease in grounding stability, and improving the safety performance of the transmission cable 12 when grounding.

[0050] When in use (working), the second drive shaft 28 is driven to rotate by the knob, and the second drive shaft 28 further drives the second worm 29 to rotate. The second worm 29 is meshed with the second worm gear 32, so that the second worm gear 32 drives the sleeve 25 to rotate, and the angle of the grounding clamp 7 is further adjusted to adapt to the grounding of the power transmission cable 12 in different directions. The connecting nut 4 is adjusted according to the direction of the power transmission cable 12, and the connecting nut 4 is threadedly connected with the pipe thread 3, so that the connecting nut 4 is raised and lowered inside the groove 2, thereby adjusting the height of the connecting nut 4. The position angle adjustment of the auxiliary clamp 11 can be achieved through the first articulated seat 34 and the second articulated seat 35, which is beneficial to the auxiliary clamp 11 and the grounding of the power transmission cable 12 in different directions. The transmission cable 12 is connected, and an external force acts on the auxiliary clamp 11, so that the transmission cable 12 squeezes the arc-shaped spring piece 15, thereby reducing the curvature of the arc-shaped spring piece 15, that is, the lower end of the arc-shaped spring piece 15 extends toward the lower end of the auxiliary clamp 11, and further opens the gap between the relative arc-shaped spring pieces 15 to facilitate the installation between the transmission cable 12 and the auxiliary clamp 11. After the transmission cable 12 is installed, the arc-shaped spring piece 15 is restored by the elastic force. At this time, the arc-shaped spring piece 15 located at the anti-slip tooth 16 is pressed against the transmission cable 12 to improve the connection stability between the transmission cable 12 and the electrical lining 17. At this time, the auxiliary clamp 11 can realize the initial fixation of the transmission cable 12, thereby improving the user's convenience in operation.

[0051] The turntable 13 is rotated to drive the first driving shaft 26 to rotate, and the first bevel gear 30 is rotated through the first driving shaft 26. The first bevel gear 30 is meshed with the second bevel gear 31 to rotate the driving shaft 23, and the first worm 24 is rotated through the driving shaft 23. The driven shaft 20 is rotated under the meshing between the first worm 24 and the first worm wheel 21, and the driven shaft 20 further drives the driven gear 22 to rotate. The meshing between the driven gear 22 and the half gear 19 makes the blocking bar 9 move inside the gap 33, so that the transmission cable 12 can be clamped between the lining bar 8 and the blocking bar. 9 and the grounding clamp 7. At this time, a triangular structure is formed between the grounding component, the auxiliary clamp 11 and the connecting nut 4, thereby improving the stability of the grounding rod 1 and reducing the large shaking of the grounding rod 1 due to external factors, so as to improve the contact stability between the grounding component, the auxiliary clamp 11 and the transmission cable 12. In addition, the "Y"-shaped grounding wire 14 can ensure that the transmission cable 12 located at the auxiliary clamp 11 and the grounding component is grounded synchronously, thereby avoiding the auxiliary clamp 11 or the grounding component from being separated from the transmission cable 12, resulting in a decrease in grounding stability, and improving the safety performance of the transmission cable 12 when grounding.
