Description

Technical Field

[0001] This utility model belongs to the field of power grid frame technology, specifically a power grid frame for power distribution networks. Background Technology

[0002] A distribution network refers to a power grid that receives electrical energy from the transmission network or power plants in a region and distributes it to various users through distribution facilities or by voltage levels.

[0003] The power grid structure used in power distribution networks varies. Depending on the specific power supply needs and the environment, in existing technologies, the power grid transmits electrical energy from power plants to various user terminals. The power distribution equipment in the power grid distributes electrical energy from substations to various user terminals, and the transformers and regulating equipment in the substations regulate the voltage and current of the electrical energy.

[0004] During the use of power grids, the connection points between cables and insulators are often relatively weak in the power grid structure, making them susceptible to external environmental impacts and wind and rain, which can lead to damage and a decline in insulation performance.

[0005] Therefore, this utility model provides a power grid frame for power distribution networks. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A power grid frame for a power distribution network, comprising a base, a power grid pole fixedly connected to the top of the base, a clamp fixedly connected to the middle of the power grid pole, two fixing frames fixedly connected to the middle of the clamp, the two fixing frames being arranged opposite each other, two screws fixedly connected to the side walls of the fixing frames, the two screws being arranged opposite each other, an mounting plate installed in the middle of the screws, an installation hole opened in the middle of the mounting plate, a nut installed in the middle of the screws, a protective box fixedly connected to the top of the mounting plate, a groove opened at the bottom of the protective box, a fixing component installed in the middle of the protective box, and protective covers installed on the top of the two protective boxes. Through the combined use of the above-mentioned protective boxes and protective covers, the connection points between insulators and cables can be effectively isolated from the outside, reducing dust and rainwater falling onto the surface of the insulators, keeping the insulators dry and clean for long-term use, providing additional mechanical protection for the connection points between insulators and cables, reducing damage and insulation performance degradation caused by external impacts, thereby improving the overall safety of the power grid.

[0008] Preferably, the fixing component includes a fixing plate with multiple positioning grooves in the center of the fixing plate. The positioning grooves are equidistantly distributed, and two rotating shafts are fixed to the sidewalls of the positioning grooves. The two rotating shafts are arranged opposite each other. A guide plate is rotatably connected to the center of each rotating shaft, and a clamping plate is fixed to the end of the guide plate. Both the guide plate and the clamping plate are arc-shaped. This structure can fix the cable in sequence, effectively reducing the problem of cable loosening and falling off due to wind or vibration. Furthermore, the fixing component can distribute the stress points of the cable, reduce the load on the suspended cable, effectively improve the cable's load-bearing capacity and stability, and effectively reduce the cable from getting tangled due to wind, thereby facilitating maintenance and management and maintaining the cable's heat dissipation effect.

[0009] Preferably, the bottom of the positioning groove is provided with two sets of fixing grooves, and the end of the clamping plate is fixed with a fixing block. The fixing block is flexibly set. The above structure can fix the clamping plate according to the size of the cable, reduce the problem of the clamping plate swaying with the cable due to wind blowing the cable, and keep the clamping plate in a stable position, thereby reducing the cable being squeezed by unstable pressure during the fixing process.

[0010] Preferably, the base has multiple sockets fixedly connected to its bottom, and each socket has a threaded ring rotatably connected to its end. A mounting rod is threadedly connected to the middle of the threaded ring, and the mounting rod is inserted into the middle of the socket. A pre-embedded plate is fixedly connected to the end of the mounting rod. This structure can effectively increase the connection points between the power grid pole and the ground, effectively improve the overall wind resistance, reduce the swaying or collapse of the power grid pole due to strong winds, and maintain the stability of power transmission by a stable power grid pole, thus reducing voltage fluctuations caused by the swaying of the power grid pole.

[0011] Preferably, one of the protective boxes has two sets of insert rods fixed to its side wall, and the other protective box has two sets of insertion holes on its middle side wall. The insertion holes are located at the corresponding positions of the insert rods. This structure allows the two protective boxes to be tightly connected to form a whole, making the connection between the two protective boxes more secure and tighter. This can resist the impact of harsh environments on the protective boxes, effectively reduce the shaking and gaps between the two protective boxes, and thus reduce their friction and wear.

[0012] Preferably, two second magnetic blocks are fixed to the top of the protective box, and two first magnetic blocks are fixed to the bottom of the protective cover. The first magnetic blocks are disposed inside the protective cover. When the first magnetic blocks and the second magnetic blocks are in contact, they attract each other. This structure makes the protective cover and the protective box more tightly connected, makes the protective cover more stable on the top of the two protective boxes, and allows the protective cover to be firmly attached to the protective box when closed, reducing the risk of falling off due to wind or vibration, and facilitating installation and disassembly during cable maintenance.

[0013] The beneficial effects of this utility model are:

[0014] 1. The power grid frame for power distribution networks described in this utility model can effectively isolate the insulator and cable connection points from the outside through the combined use of protective boxes and protective covers. This reduces dust and rainwater falling onto the insulator surface, keeps the insulators dry and clean for long-term use, provides additional mechanical protection for the insulator and cable connection points, reduces damage and insulation performance degradation caused by external impacts, and thus improves the overall safety of the power grid.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown in the figure, a power grid frame for a power distribution network according to an embodiment of the present invention includes a base 1, a power grid pole 10 fixedly connected to the top of the base 1, a clamp 11 fixedly connected to the middle of the power grid pole 10, two fixing frames 12 fixedly connected to the middle of the clamp 11, the two fixing frames 12 being arranged opposite each other, two screws 13 fixedly connected to the side wall of the fixing frames 12, the two screws 13 being arranged opposite each other, an mounting plate 15 installed in the middle of the screw 13, an mounting hole 18 opened in the middle of the mounting plate 15, a nut 14 installed in the middle of the screw 13, a protective box 16 fixedly connected to the top of the mounting plate 15, a groove 17 opened at the bottom of the protective box 16, a fixing component 2 installed in the middle of the protective box 16, and protective covers 19 installed on the top of the two protective boxes 16. In operation, the two protective boxes 16 are placed correspondingly in the middle of the two screws 13 through the mounting plate 15, the side walls of the two protective boxes 16 are tightly fitted, and then the nuts 14 are inserted from the ends of the screws 13. Rotate the nut 14 to fix the protective box 16 to both sides of the insulator. At this time, the insulator is in the middle of the two grooves 17. Straighten the cable on the insulator and place it in the middle of the fixing component 2 so that the cable is fixed in sequence. After the cable is fixed, place the protective cover 19 on top of the two protective boxes 16. The top of the two protective boxes 16 enters the protective cover 19. The protective box 16 and the protective cover 19 protect the connection position of the insulator and the cable. Through the above structure, the protective box 16 and the protective cover 19 can effectively isolate the connection position of the insulator and the cable from the outside, reduce the dust and rainwater in the environment from falling on the surface of the insulator, keep the insulator dry and clean for a long time, provide additional mechanical protection for the connection position of the insulator and the cable, reduce the problem of damage and insulation performance degradation caused by external impact, and thus improve the overall safety of the power grid.

[0025] like Figures 1 to 5As shown, the fixing assembly 2 includes a fixing plate 21. Multiple positioning slots 22 are equidistantly distributed in the center of the fixing plate 21. Two rotating shafts 23 are fixedly connected to the side walls of each positioning slot 22, and the two rotating shafts 23 are arranged opposite each other. A guide plate 24 is rotatably connected to the center of each rotating shaft 23, and a clamping plate 25 is fixedly connected to the end of each guide plate 24. Both the guide plate 24 and the clamping plate 25 are arc-shaped. During operation, after the cable connection is completed, each cable is placed in the center of its corresponding positioning slot 22. First, the cable contacts the two guide plates 24, and pressure is applied to the bottom of the cable. The guide plate 24 rotates in the center of the rotating shaft 23 under pressure. At this time, the cable enters the center of the two clamping plates 25, allowing the cable to pass through... The clamping plate 25 clamps and fixes a single cable. The clamping plate 25 is elastically set and bends elastically according to the size of the cable. A torsion spring is provided at the connection between the guide plate 24 and the rotating shaft 23. When the cable is removed, the torsion spring causes the guide plate 24 to drive the clamping plate 25 to return to its original position. The above structure can fix the cable in sequence, effectively reducing the problem of the cable loosening and falling off due to wind or vibration. In addition, the fixing component 2 can distribute the stress points of the cable, reduce the load on the suspended cable, effectively improve the cable's load-bearing capacity and stability, and effectively reduce the cable from getting tangled due to wind, thus facilitating maintenance and management and maintaining the cable's heat dissipation effect.

[0026] like Figure 4 and Figure 5 As shown, the bottom of the positioning groove 22 is provided with two sets of fixing grooves 3. The end of the clamping plate 25 is fixed with a fixing block 31. The fixing block 31 is flexibly set. When the clamping plate 25 is squeezed and bent during operation, the end moves to both sides. At the same time, the flexibility of the fixing block 31 enters the middle of the corresponding fixing groove 3. At this time, the fixing block 31 is stuck inside the fixing groove 3, thereby fixing the clamping plate 25. When the cable is blown by the wind, the clamping plate 25 keeps the cable position. The above structure can fix the clamping plate 25 according to the size of the cable, reducing the problem of the clamping plate 25 swaying with the cable when the wind blows the cable. It can keep the clamping plate 25 in a stable position, thereby reducing the cable being squeezed by unstable compression during the fixing process.

[0027] like Figure 2As shown, multiple sockets 4 are fixedly connected to the bottom of the base 1. Threaded rings 41 are rotatably connected to the ends of the sockets 4. A mounting rod 42 is threadedly connected to the middle of the threaded ring 41. The mounting rod 42 is inserted into the middle of the socket 4. A pre-embedded plate 43 is fixedly connected to the end of the mounting rod 42. During operation, the end of the mounting rod 42 is inserted into the socket 4, and the threaded ring 41 is rotated to connect the end of the mounting rod 42 to the socket 4. The bottom of the power grid pole 10 is installed in the excavated pit at the designated location. The base 1 is fixed to the ground, and then multiple pre-embedded plates 43 are buried underground. This structure effectively increases the connection points between the power grid pole 10 and the ground, effectively improving the overall wind resistance and reducing the swaying or collapse of the power grid pole 10 due to strong winds. A stable power grid pole 10 can maintain the stability of power transmission and reduce voltage fluctuations caused by the swaying of the power grid pole 10.

[0028] like Figure 3 and Figure 5 As shown, one of the protective boxes 16 has two sets of insert rods 5 fixed to its side wall, and the other protective box 16 has two sets of insertion holes 51 on its middle side wall. The insertion holes 51 are located at the corresponding positions of the insert rods 5. During operation, when the two protective boxes 16 are installed, the ends of the insert rods 5 are inserted into the corresponding insertion holes 51 to accurately position the two protective boxes 16 and make them fit tightly together. Through the above structure, the two protective boxes 16 can be tightly connected to form a whole, and the connection between the two protective boxes 16 is more solid and tight. It can resist the impact of harsh environment on the protective boxes 16, effectively reduce the shaking and gaps between the two protective boxes 16, thereby reducing their friction and wear.

[0029] like Figure 3 and Figure 5 As shown, two second magnetic blocks 61 are fixed to the top of the protective box 16, and two first magnetic blocks 6 are fixed to the bottom of the protective cover 19. The first magnetic blocks 6 are located inside the protective cover 19. When the first magnetic blocks 6 and the second magnetic blocks 61 are in contact, they attract each other. During operation, after the two protective boxes 16 are fixed, the protective cover 19 is placed directly on the top of the two protective boxes 16. At this time, the first magnetic blocks 6 and the second magnetic blocks 61 are close together and attract each other, so that the protective cover 19 is fixed on the top of the two protective boxes 16. When the cable is adjusted or repaired, the protective cover 19 is moved upward to separate the first magnetic blocks 6 and the second magnetic blocks 61. The above structure can make the protective cover 19 and the protective box 16 more tightly connected, and make the protective cover 19 more stable on the top of the two protective boxes 16. It can also make the protective cover 19 firmly attached to the protective box 16 when closed, reducing the risk of falling off due to wind or vibration, and facilitating installation and disassembly during cable repair.

[0030] like Figure 4As shown, a rubber pad 7 is installed in the middle of the clamping plate 25. The rubber pad 7 is fixed in the middle of the clamping plate 25. During operation, when the cable enters between the two clamping plates 25, it first contacts the cable through the rubber pad 7. Due to the flexibility of the rubber pad 7, it fits tightly with the cable. The above structure can effectively reduce the friction between the cable and the clamping plate 25. The flexible material of the rubber pad 7 can reduce the wear caused by the cable being fixed and squeezed for a long time, thus reducing the frequency and cost of replacement or maintenance.

[0031] During operation, the two protective boxes 16 are placed in the middle of the two screws 13 via the mounting plate 15, with the side walls of the two protective boxes 16 tightly fitted. Then, the nuts 14 are rotated from the ends of the screws 13 to fix the protective boxes 16 to both sides of the insulator. At this time, the insulator is in the middle of the two grooves 17. The cable on the insulator is straightened and placed in the middle of the fixing assembly 2 to fix the cable in sequence. After the cable is fixed, the protective cover 19 is placed on top of the two protective boxes 16, with the tops of the two protective boxes 16 entering the protective cover 19. The insulator and cable are connected through the protective boxes 16 and the protective cover 19. After the cable connection is completed, each cable is placed in the center of its corresponding positioning slot 22. First, the cable contacts the two guide plates 24, applying pressure to the bottom. The guide plates 24 rotate in the center of the rotating shaft 23 under pressure. At this time, the cable enters the center of the two clamping plates 25, which clamp and fix the individual cable. The clamping plates 25 are elastically designed, bending elastically according to the cable size. A torsion spring is provided at the connection between the guide plate 24 and the rotating shaft 23. When the cable is removed, the torsion spring causes the guide plate 24 to move the clamping plates 25 back to their original position. When the clamping plates 25 are compressed and bent... The end moves to both sides, and at the same time, the flexible fixing block 31 enters the middle of the corresponding fixing groove 3. At this time, the fixing block 31 is stuck inside the fixing groove 3, thereby fixing the clamping plate 25. When the cable is blown by the wind, the clamping plate 25 keeps the cable in position. Insert the end of the mounting rod 42 into the socket 4, rotate the threaded ring 41 to connect the end of the mounting rod 42 to the socket 4, and install the bottom of the power grid pole 10 in the foundation pit dug at the designated location. The base 1 is fixed to the ground, and then multiple pre-embedded plates 43 are buried underground. When the two protective boxes 16 are installed, the end of the plug rod 5 is inserted into the corresponding plug hole 51. Accurately position the two protective boxes 16 so that they fit tightly together. After the two protective boxes 16 are fixed, place the protective cover 19 directly on top of the two protective boxes 16. At this time, the first magnetic block 6 and the second magnetic block 61 are close together and attract each other, so that the protective cover 19 is fixed on top of the two protective boxes 16. When the cable is adjusted or repaired, move the protective cover 19 upward to separate the first magnetic block 6 and the second magnetic block 61. When the cable enters between the two clamping plates 25, it first contacts the cable through the rubber pad 7 and fits tightly with the cable due to the flexibility of the rubber pad 7.

[0032] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
