Description

Technical Field

[0001] The present invention relates to the technical field of grounding devices, and more particularly to a grounding assembly for electrical equipment. Background Art

[0002] The grounding components of electrical equipment are a key link to ensure the safe operation of the system and the safety of personnel. The grounding components establish a low-impedance electrical connection between the electrical equipment and the earth, effectively guiding fault current, lightning current and electrostatic charge to the ground, thereby protecting the equipment and personnel from electrical hazards. However, in actual applications, especially for electrical equipment in outdoor environments, the grounding component connections are often exposed to harsh natural environments for a long time, such as moisture, acid and alkali corrosion, temperature changes, etc. These factors will accelerate the oxidation and corrosion process of the grounding component connections.

[0003] Oxidation and rust will not only reduce the conductivity of grounding components, resulting in increased grounding resistance, but may also cause "false grounding" or poor grounding. When the grounding resistance exceeds the specified range, it will seriously affect the grounding effect of electrical equipment and may even cause serious consequences such as equipment failure, fire or electric shock accidents.

[0069] The core of the present invention is to provide a grounding component for electrical equipment to slow down the oxidation and corrosion process of the grounding component and avoid the increase of grounding resistance and poor grounding caused by oxidation and corrosion.

[0070] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0071] like Figure 1-Figure 9 As shown, an embodiment of the present invention discloses an electrical equipment grounding assembly, which includes a grounding main body device 100 and a protective assembly 200.

[0072] Among them, the grounding main device 100 is used to connect the electrical equipment 300 with the earth to establish a low-impedance electrical connection between the electrical equipment 300 and the earth, effectively guiding fault current, lightning current and electrostatic charge to the ground, thereby protecting equipment and personnel from electrical hazards.

[0073] The protection component 200 at least includes a sealing component 201 and a fixing component 202, and the sealing component 201 is fixed by the fixing component 202 so that the sealing component 201 is covered on the outside of the grounding main device 100. It can be understood by those skilled in the art that the grounding main device 100 is usually an irregular structure, so it is difficult for the integrated sealing component 201 to be sleeved on the outside of the grounding main device 100, so it is necessary to divide the sealing component 201 into multiple parts, and then fix them by the fixing component 202, so that the sealing component 201 is conveniently covered on the outside of the grounding main device 100.

[0074] The electrical equipment grounding assembly provided by the present invention adds a protective assembly 200 on the basis of the grounding main device 100, and the protective assembly 200 at least includes a sealing assembly 201 and a fixing assembly 202, and the sealing assembly 201 is fixed by the fixing assembly 202, and the sealing assembly 201 is covered on the outside of the grounding main device 100. The present invention protects the grounding main device 100 through the sealing assembly 201, which can prevent the grounding main device 100 from being exposed to a harsh natural environment, reduce its oxidation and corrosion process, and then prevent the increase of grounding resistance and poor grounding caused by oxidation and corrosion.

[0075] like Figure 3 and Fig. 9 As shown, in a specific embodiment of the present invention, the grounding main body device 100 may include a fixing column 102, a fixing plate 103 and a grounding assembly 104. The fixing column 102 is used to be arranged on one side of the electrical device 300 and is used to be electrically connected to the electrical device 300.

[0076] The fixing plate 103 is arranged on the side of the fixing column 102 away from the electrical device 300, and is electrically connected to the fixing column 102. It should be noted that the fixing plate 103 and the fixing column 102 can be designed as an integrated structure, or can be designed and assembled in a split manner. The fixing plate 103 and the fixing column 102 can both be cylindrical and coaxially arranged, and the diameters of the two should be different. The diameter of the fixing plate 103 should be larger than the diameter of the fixing column 102, so as to form a shaft shoulder 101 between the two, and provide a limit for the installation of the sealing assembly 201.

[0077] The grounding component 104 is electrically connected to the fixing plate 103 and the earth respectively, so that the current on the surface of the electrical device 300 can be introduced to the fixing plate 103 through the fixing column 102, and then introduced from the fixing plate 103 to the grounding component 104, and then introduced to the earth.

[0078] Furthermore, the grounding assembly 104 may include a fixing screw 104a, a fixing nut 104d, a grounding wire 104f, a grounding plate 104b and a positioning sleeve 104c. The grounding wire 104f is electrically connected to the grounding plate 104b for grounding.

[0079] The fixing screw 104a is arranged on the side of the fixing plate 103 away from the fixing column 102. It should be noted that the fixing screw 104a and the fixing plate 103 can be designed as an integrated structure, or can be designed and assembled in a split manner. The fixing plate 103 and the fixing screw 104a can both be cylindrical and coaxially arranged, and the diameters of the two should be different. The diameter of the fixing plate 103 should be larger than the diameter of the fixing screw 104a to form a shaft shoulder between the two to provide a limit for the installation of the grounding plate 104b.

[0080] The grounding sheet 104b and the positioning sleeve 104c are both sleeved on the fixing screw 104a, and the fixing nut 104d is threadedly matched with the fixing screw 104a, so that the grounding sheet 104b is pressed against the fixing disk 103 through the positioning sleeve 104c. That is, by rotating the fixing nut 104d, the positioning sleeve 104c and the grounding sheet 104b can be pushed to move in a direction close to the fixing disk 103 until the grounding sheet 104b is pressed against the fixing disk 103, thereby achieving electrical connection with the fixing disk 103. In this embodiment, by providing the positioning sleeve 104c, the thrust generated by the fixing nut 104d can be applied to the grounding sheet 104b, so that a stable electrical connection is achieved between the grounding sheet 104b and the fixing disk 103.

[0081] In order to prevent the fixing nut 104d from loosening and affecting the electrical connection between the grounding plate 104b and the fixing plate 103, in this embodiment, the grounding assembly 104 further includes a compression spring 104e. The compression spring 104e is sleeved on the fixing screw 104a, and one end of the compression spring 104e abuts against the fixing nut 104d, and the other end abuts against the grounding plate 104b.

[0082] After the fixing nut 104d presses the grounding plate 104b onto the fixed disk 103 through the positioning sleeve 104c, the fixing nut 104d also squeezes and deforms the extrusion spring 104e, so that the extrusion spring 104e stores energy. The spring force of the extrusion spring 104e can also squeeze the grounding plate 104b. After the fixing nut 104d is loosened, it is unable to provide a large pressing force for the grounding plate 104b. At this time, the extrusion spring 104e can continue to press the grounding plate 104b onto the fixed disk 103, thereby avoiding the phenomenon of poor contact between the grounding plate 104b and the fixed disk 103 caused by the loosening of the fixing nut 104d and the positioning sleeve 104c.

[0083] It should be noted that the extrusion spring 104e can be located inside the positioning sleeve 104c, or can be sleeved outside the positioning sleeve 104c. When arranged inside the positioning sleeve 104c, a hole can be opened on the positioning sleeve 104c to facilitate applying conductive paste to the extrusion spring 104e through the hole on the positioning sleeve 104c.

[0084] like Figure 2 , Figure 5 and Figure 6 As shown, in a specific embodiment of the present invention, the sealing assembly 201 includes a bottom shell 201a, a first sealing shell 201b, a second sealing shell 201c and a sheath 201e.

[0085] The bottom shell 201a covers the lower part of the fixed column 102 and extends in the direction of the fixed screw 104a. In order to prevent the bottom shell 201a from moving in the axial direction, the portion of the bottom shell 201a corresponding to the fixed column 102 can have a larger thickness so that it can fit on the outer wall of the fixed column 102, and the portion of the bottom shell 201a with a larger thickness can also abut on the shoulder 101 between the fixed disk 103 and the fixed column 102, thereby limiting the axial movement of the bottom shell 201a. It should be noted that the length of the bottom shell 201a in the axial direction should be able to cover the fixed disk 103, the fixed column 102 and the fixed screw 104a.

[0086] The first sealed shell 201b and the second sealed shell 201c are located above the bottom shell 201a. The first sealed shell 201b and the second sealed shell 201c can be designed to have the same structure and be symmetrically arranged. Both are arranged above the bottom shell 201a to make up for the missing part above the bottom shell 201a, so that the grounding sealing body composed of the first sealed shell 201b, the second sealed shell 201c and the bottom shell 201a can completely cover the main part of the grounding main device 100 along the circumferential direction.

[0087] The cooperation of the bottom shell 201a, the first sealing shell 201b and the second sealing shell 201c can seal the entire grounding component 104, so that the oxidation and rust of the grounding component 104 caused by the external environment is in a very small state. The sealing strips are arranged at the connection between the bottom shell 201a, the first sealing shell 201b and the second sealing shell 201c to improve their sealing performance, so as to prevent rainwater and dust from entering the interior through the gaps between the three and causing rust to the grounding main device 100.

[0088] Since the grounding wire 104f needs to extend out of the grounding sealing body, a sheath 201e is added in this embodiment, and the sheath 201e is wrapped around the outside of the grounding wire 104f to protect the grounding wire 104f.

[0089] like Figure 6 As shown, the fixing assembly 202 includes connecting bolts 202a, and the first sealing shell 201b and the second sealing shell 201c are fixed to the bottom shell 201a by the connecting bolts 202a. Specifically, the matching part of the connecting bolts 202a and the bottom shell 201a should be the thicker part of the bottom shell 201a, that is, the part matching with the fixing column 102.

[0090] In order to facilitate the tightening and loosening of the connecting bolt 202a, the connecting bolt 202a usually needs to be exposed to the outside. In order to shield and seal the connecting bolt 202a, the fixing assembly 202 disclosed in this embodiment may also include a sealing plate 202d and a clamping portion, such as Figure 5 and Figure 6 As shown, the first sealed shell 201b and the second sealed shell 201c cooperate with the fixing column 102 and have a mounting platform for mounting the connecting bolts 202a, and the sealing plate 202d is arranged above the mounting platform of the first sealed shell 201b and the second sealed shell 201c to shield the connecting bolts 202a. The sealing plate 202d is used to seal one side of the first sealed shell 201b and the second sealed shell 201c to prevent the connecting bolts 202a from being exposed to the outside.

[0091] Both the first sealing shell 201b and the second sealing shell 201c are provided with an embedded card slot, and the card portion is provided on the side of the sealing plate 202d facing the mounting platform, and the card portion is embedded in the embedded card slot. Specifically, after the connecting bolt 202a is tightened, the sealing plate 202d is sleeved on the first sealing shell 201b and the second sealing shell 201c, so that the connecting bolt 202a is sealed inside through the sealing plate 202d. The card portion on the sealing plate 202d is embedded in the embedded card slot, so as to realize the fixing of the sealing plate 202d on the first sealing shell 201b and the second sealing shell 201c. It should be noted that the card portion and the sealing plate 202d can be designed as an integrated structure.

[0092] Further, the clamping part may include a support block 202e and a clamping block 202f, wherein the clamping block 202f is used to be embedded in the embedded card slot, and the clamping block 202f is arranged at one end of the support block 202e, and the other end of the support block 202e is arranged on the sealing plate 202d. The support block 202e has a certain elasticity, and the clamping blocks 202f on the two support blocks 202e form an inwardly clasping effect. When installing the sealing plate 202d, it is necessary to press the sealing plate 202d downward, and the entity part of the embedded card slot is provided on the first sealing shell 201b and the second sealing shell 201c, so that the two support blocks 202e can be opened until the clamping block 202f slides into the embedded card slot. When disassembling the sealing plate 202d, a large external force is required to deform the two support blocks 202e outward, so that the clamping block 202f slides out of the embedded card slot.

[0093] Furthermore, the fixing assembly 202 may also include a fixing ring 202b and a clamping strip 202c, wherein the fixing ring 202b is sleeved on the outer surfaces of the bottom shell 201a, the first sealing shell 201b and the second sealing shell 201c. Specifically, the fixing ring 202b and the sealing plate 202d may be respectively arranged at the two ends of the grounding sealing body composed of the bottom shell 201a, the first sealing shell 201b and the second sealing shell 201c.

[0094] like Figure 7 As shown, the clamping strip 202c is arranged on one side of the first sealing shell 201b, and a slide groove U for the clamping strip 202c to be inserted is provided in the second sealing shell 201c. That is, the clamping strip 202c is arranged on the end surface where the first sealing shell 201b and the second sealing shell 201c are connected, and the slide groove U is arranged on the end surface where the second sealing shell 201c and the first sealing shell 201b are connected. When installing, the clamping strip 202c is inserted into the slide groove U from one end of the slide groove U, and continuously pushed forward until the end surfaces of the first sealing shell 201b and the second sealing shell 201c are aligned. The clamping strip 202c can be a T-shaped clamping strip, so that the direction in which the first sealing shell 201b and the second sealing shell 201c are away from each other is limited by the clamping strip 202c and the slide groove U, that is, the clamping strip 202c can slide in the slide groove U, so that the first sealing shell 201b and the second sealing shell 201c are mutually limited, thereby improving the stability of assembly.

[0095] In a specific embodiment of the present invention, the electrical equipment grounding component may also include an application component 203, and the bottom shell 201a, the first sealed shell 201b and the second sealed shell 201c are surrounded by a conductive paste storage space. The cross-section of the bottom shell 201a can be a semicircular structure. Before the first sealed shell 201b and the second sealed shell 201c, the conductive paste is first filled in the bottom shell 201a, so that the conductive paste is stored in the conductive paste storage space for future use.

[0096] The smearing component 203 is used to smear the conductive paste in the conductive paste storage space onto the fixed disk 103 and the grounding component 104. The smearing component 203 can realize the smearing action in an automatic manner or in a manual manner. In this embodiment, by smearing the conductive paste onto the fixed disk 103 and the grounding component 104, the conductive performance of the grounding main device 100 can be improved, and its anti-oxidation ability can be enhanced, thereby improving reliability.

[0097] Further, such as Figure 3 and Figure 4 As shown, in this embodiment, the application assembly 203 includes a support ring 203a, a rotating ring 203b and a cotton felt wheel 203c. The support ring 203a is arranged in the conductive paste storage space and is located in the radial direction of the fixed disk 103, the rotating ring 203b is rotatably supported in the support ring 203a and has a gap with the fixed disk 103, and the cotton felt wheel 203c is arranged on the rotating ring 203b and fits with the fixed disk 103.

[0098] The support ring 203a is used to support the rotating circle 203b so that the rotating circle 203b can rotate stably. When the rotating circle 203b rotates, it can drive the cotton felt wheel 203c to rotate, so that the conductive paste in the bottom shell 201a adheres to the surface of the cotton felt wheel 203c, so that during the rotation of the cotton felt wheel 203c, the conductive paste is applied to the grounding plate 104b and the fixed disk 103, thereby increasing the conductive performance of the grounding plate 104b and the fixed disk 103, and enhancing the anti-oxidation ability of the grounding plate 104b and the fixed disk 103.

[0099] It should be noted that, in order to ensure that the cotton felt wheel 203c can be stained with the conductive paste, the cotton felt wheel 203c should be fixed on the end surface of the rotating circle 203b close to the conductive paste storage space, so that when the cotton felt wheel 203c rotates, it can continue to be stained with the conductive paste in the conductive paste storage space. One side of the cotton felt wheel 203c can be attached to the grounding sheet 104b, and the inner peripheral surface can be attached to the outer peripheral surface of the fixed disk 103, so that the conductive paste is applied to the grounding sheet 104b and the fixed disk 103.

[0100] Furthermore, the smearing assembly 203 may also include a rotating ring 203d, a rotating frame 203e and a smearing plate 203f. There are two supporting rings 203a, which are respectively arranged at the two ends of the conductive paste storage space, one supporting ring 203a is used to support the rotating ring 203b, and the other supporting ring 203a is used to support the rotating ring 203d, that is, the rotating ring 203d is rotatably supported in the hole of the supporting ring 203a.

[0101] Please combine Figure 7 and Figure 8 The rotating frame 203e is arranged on one side of the rotating ring 203d, and the rotating frame 203e is located outside the fixed screw 104a, and the rotating frame 203e has a plurality of through holes. One end of the rotating frame 203e is fixed to or designed as a whole with the rotating ring 203d, so that the two can rotate synchronously. The other end of the rotating frame 203e should have a gap with the grounding plate 104b to prevent the two from rubbing against each other.

[0102] The smear plate 203f is arranged in the rotating frame 203e, and is used to smear the conductive paste in the conductive paste storage space onto the fixing nut 104d and the positioning sleeve 104c. The smear plate 203f can be fixed on the inner wall of the rotating frame 203e, and is located outside the fixing nut 104d and the positioning sleeve 104c. When the rotating frame 203e rotates, the smear plate 203f is driven to rotate, and the conductive paste is smeared onto the fixing nut 104d and the positioning sleeve 104c.

[0103] Specifically, when the rotating ring 203d rotates, it can drive the rotating frame 203e to rotate synchronously. The surface of the rotating frame 203e is provided with a plurality of through holes. When the rotating frame 203e rotates, it can drive the smear plate 203f to rotate around the fixing nut 104d and the positioning sleeve 104c, so that the conductive paste in the bottom shell 201a is scraped onto the smear plate 203f, and with the movement of the smear plate 203f, the conductive paste is smeared onto the surface of the fixing nut 104d and the positioning sleeve 104c. Since the surface of the positioning sleeve 104c is provided with a plurality of through holes, the conductive paste can be smeared onto the extrusion spring 104e inside the positioning sleeve 104c. A plurality of smear plates 203f can be provided, and they are evenly fixed on the inner wall of the rotating frame 203e; of course, only one smear plate 203f can be provided, and the number of smear plates 203f is not limited in this embodiment.

[0104] It should be noted that the application component 203 can be rotated manually, and a corresponding rotation handle needs to be provided externally, and the application component 203 can also be driven to rotate by other devices. In a specific embodiment of the present invention, the electrical equipment grounding component also includes a driving component 204 for driving the application component 203 to move.

[0105] like Figure 3 and Figure 5 As shown, the driving assembly 204 includes a rotating rod 204d, a connecting rod 204g, a transmission shaft 204i and a driving motor 204a. The rotating rod 204d is rotatably supported on the bottom shell 201a, and a driving disk 204f is fixed to one end of the rotating rod 204d located inside the bottom shell 201a. Specifically, a supporting sleeve 204c can be embedded in the hole of the bottom shell 201a for supporting the rotating rod 204d, and the rotating rod 204d is rotatably supported on the supporting sleeve 204c. The supporting sleeve 204c can reduce the friction with the rotating rod 204d, so that the rotating rod 204d rotates more smoothly.

[0106] Please combine Figure 8 As shown, there are multiple connecting rods 204g, and one end is set on the driving disk 204f, and the other end is set on the rotating ring 203d. The driving disk 204f and the rotating ring 203d are realized by multiple connecting rods 204g, so that the driving disk 204f and the rotating ring 203d can rotate synchronously.

[0107] Transmission gears 204j are fixed at both ends of the transmission shaft 204i, one of the transmission gears 204j is meshed with the rotating circle 203b, and the other transmission gear 204j is meshed with the rotating ring 203d. Under the action of the transmission shaft 204i, the power transmission between the rotating ring 203d and the rotating circle 203b is realized, so that the rotating ring 203d and the rotating circle 203b can rotate at the same time. The transmission shaft 204i is rotatably supported on a fixing frame 204h, and the fixing frame 204h is set on the inner wall of the bottom shell 201a. The fixing frame 204h is used to support the transmission shaft 204i so that the transmission shaft 204i can rotate stably.

[0108] The driving motor 204a is transmission-connected to the rotating rod 204d; specifically, the driving motor 204a can be transmission-connected to the rotating rod 204d via the driving gear 204b and the rotating wheel 204e, the driving gear 204b is disposed on the output shaft of the driving motor 204a, the rotating wheel 204e is disposed on the rotating rod 204d, the driving gear 204b and the rotating wheel 204e are meshed with each other, and in this embodiment, the power output by the driving motor 204a is transmitted to the rotating rod 204d via the meshing driving gear 204b and the rotating wheel 204e.

[0109] The drive motor 204a can be controlled by a controller disposed in the electrical equipment 300. The staff can remotely control the switch of the drive motor 204a through the controller, and the controller can also be combined with a timer to make the drive motor 204a run a certain number of circles after a certain period of time. The above-mentioned methods and devices for controlling the drive motor 204a are all existing technologies and will not be elaborated here.

[0110] When installing the protective component 200, a certain amount of conductive paste needs to be injected into the bottom shell 201a. When the conductive paste needs to be applied to the surface of the grounding component 104, the driving motor 204a can be remotely driven to start, so that the driving motor 204a drives the driving gear 204b to rotate. Since the driving gear 204b is engaged with the rotating wheel 204e, the driving gear 204b drives the rotating wheel 204e to rotate.

[0111] The rotating wheel 204e drives the driving disk 204f to rotate through the rotating rod 204d, and the driving disk 204f drives the connecting rod 204g to rotate, thereby driving the rotating ring 203d to rotate. When the rotating ring 203d rotates, it can drive the rotating frame 203e to rotate. The surface of the rotating frame 203e is provided with a plurality of through holes. When the rotating frame 203e rotates, it can drive the smear plate 203f to move, so that the conductive paste in the bottom shell 201a is scraped onto the smear plate 203f, and with the movement of the smear plate 203f, the conductive paste is smeared onto the surface of the fixing nut 104d and the positioning sleeve 104c. Since the surface of the positioning sleeve 104c is provided with a plurality of through holes, the conductive paste can be smeared onto the extrusion spring 104e inside the positioning sleeve 104c.

[0112] Since the rotating ring 203d and the transmission gear 204j are meshed, when the rotating ring 203d rotates, it can drive the transmission gear 204j to rotate, so that through the connection of the transmission shaft 204i, the other transmission gear 204j can drive the rotating circle 203b to rotate. When the rotating circle 203b rotates, it can drive the cotton felt wheel 203c to rotate, so that the conductive paste in the bottom shell 201a is attached to the surface of the cotton felt wheel 203c, so that in the process of rotation of the cotton felt wheel 203c, the conductive paste is applied to the grounding plate 104b and the fixed disk 103, thereby increasing the conductive performance of the grounding plate 104b and the fixed disk 103, and enhancing the antioxidant capacity of the grounding plate 104b and the fixed disk 103.

[0113] Furthermore, the sealing assembly 201 may also include a protective cover 201d, the bottom shell 201a, the first sealing shell 201b and the second sealing shell 201c form a grounding sealing body, the protective cover 201d is sealed and arranged at one end of the grounding sealing body away from the electrical device 300, and the driving motor 204a, the driving gear 204b, the rotating wheel 204e and the partial structure of the rotating rod 204d are located in the protective cover 201d. In this embodiment, the protective cover 201d for protecting the driving assembly 204 is added to improve the safety of the device during operation.
