The distribution network generally includes the following key elements: Transmission lines: Transmit electricity from power plants or substations to distribution stations closer to users. Distribution stations: Reduce the high voltage of transmission lines to a voltage level suitable for users. Distribution lines: Distribute electricity from distribution stations to individual users. Transformers: Convert voltage between distribution stations and users to ensure that electricity is transmitted at the correct voltage level. Switchgear: Includes circuit breakers, disconnectors, etc. Distribution automation system: Uses advanced sensors, controllers and communication technologies to achieve real-time monitoring and management of the distribution network. Protection devices: Such as relays and circuit breakers, used to detect and isolate faults and protect the power system from damage.

[0019] The present invention provides a combined lightning protection device for power distribution network lines, which has the following beneficial effects:

[0020] The invention relates to a combined lightning protection device for power distribution network lines. The mounting frame provides mechanical fixation to ensure that the lightning rod can remain stable when subjected to external forces during use. The design of the mounting frame allows the lightning rod to be quickly disassembled when maintenance or replacement is required, which is convenient for inspection and maintenance. The compression spring member applies pre-pressure to ensure that the clamp ring is in close contact with the lightning rod, thereby reducing vibration and displacement that may occur in the operation of the lightning rod. The stable mechanical fixation and pre-pressure of the compression spring member increase the safety of the lightning rod under adverse weather conditions. At the same time, the design of the compression spring member allows the clamp ring to expand the spacing when the lightning rod is inserted. After installation, the clamp ring can be pushed back to fit closely to the lightning rod through the rebound property, thereby providing a certain degree of adjustability and being able to adapt to lightning rods of different sizes.

[0021] The combined lightning protection device for power distribution network lines has a protective mechanism that provides physical protection for the lightning rod, prevents external objects from directly hitting the lightning rod, reduces its failure due to physical damage, and can isolate the lightning rod from environmental factors, thereby extending the service life of the lightning rod. At the same time, the first protective shell and the second protective shell are designed to be detachable, which facilitates the inspection and maintenance of the lightning rod by operators, and also protects the safety of maintenance personnel. The installation screw plate is threadedly connected by the installation screw plate, which enhances the stability of the overall structure and helps the stability of the lightning rod under severe weather conditions. The design of the mutual engagement of the plug strip and the slot simplifies the installation process of the protective mechanism, making assembly and disassembly more convenient. The design of the insulating layer can prevent operators from accidentally getting electric shock during the installation or maintenance of the lightning rod, and can provide additional electrical safety protection. The design of the insulating layer helps to protect the first protective shell and the second protective shell from erosion by environmental factors such as moisture, salt spray, and chemicals, thereby extending the service life of the protective mechanism.

[0022] The combined lightning protection device for power distribution network lines can manually rotate the adjusting screw by turning the handle, so that the operator can quickly connect or disconnect the connection between the second grounding wire and the third grounding wire and the coupler, thereby improving the efficiency of installation and maintenance, facilitating maintenance and inspection, simplifying the operation process, and reducing the dependence on professional tools. The adjusting screw allows the operator to make precise adjustments according to the thickness of the wire to ensure good contact and a stable connection between the wire and the coupler. The clamping plate is driven by the adjusting screw to push the anti-skid pad to fit closely to the outer walls on both sides of the wire end, thereby ensuring the stability and reliability of the electrical connection. At the same time, the anti-skid pad can also prevent the wire from sliding when subjected to vibration or external force, providing additional mechanical stability and protecting the wire from damage.

[0023] The invention relates to a combined lightning protection device for power distribution network lines. The dispersed arrangement of grounding rods and telescopic grounding rods expands the contact area between the grounding device and the ground and forms a point-mesh distribution, which helps to improve its grounding efficiency and reduce the grounding resistance. The telescopic grounding rods with point-mesh distribution can disperse the current more evenly and reduce the current density, thereby improving the grounding effect and safety. Through the dispersed support of multiple grounding rods and telescopic grounding rods, the entire grounding device is more stable in the ground and can withstand greater mechanical pressure and environmental stress. The design of the telescopic grounding rod allows the device to adapt to soils of different depths and different types of geological structures, ensuring effective grounding in a variety of environments.

[0024] The combined lightning protection device for power distribution network lines uses a driving gear and a driven gear to mesh, and can simultaneously drive multiple driven gears to rotate through one driving gear, so as to simultaneously drive multiple grounding rods to be inserted into the soil, without having to operate each grounding rod one by one, reducing labor intensity and simplifying the manual operation process, so that the operator can easily drive the telescopic grounding rod deep into the soil, ensuring that the grounding device can be firmly fixed on the ground, providing effective lightning protection for the power distribution network lines, and through the gear meshing of the driving gear and the driven gear, the operator can accurately control the descending speed and depth of the telescopic grounding rod to ensure that it accurately reaches the required position, and the supporting screw plate can provide additional structural stability to ensure the stability of the gear system during operation.

[0037] See also Figures 1 to 8The present invention provides a technical solution: a combined lightning protection device for a power distribution network line, comprising an installation frame 1, a lightning rod 2 is engaged at the bottom of the installation frame 1, a first grounding wire 3 is provided at the bottom of the lightning rod 2, an intelligent surge protector 4 is provided at the bottom end of the first grounding wire 3, a second grounding wire 5 is connected to the bottom end of the intelligent surge protector 4, a coupler 6 is connected to the bottom end of the second grounding wire 5, a third grounding wire 7 is connected to the lower end of the coupler 6, a grounding device 8 is connected to the bottom end of the third grounding wire 7, a driving mechanism 9 for driving the grounding device 8 to move is arranged on the grounding device 8, and a protective mechanism 10 is provided on the outer wall of the lightning rod 2.

[0038] As a preferred embodiment, the grounding device 8 includes a grounding main rod 801, a grounding branch rod 802, a connecting rod 8021, a telescopic grounding rod 803, a slide groove 8031 ​​and a support plate 804. The grounding main rod 801 is fixedly connected to the support plate 804 by welding. The first end of the grounding branch rod 802 is welded and fixed to the outer wall of the support plate 804. The grounding branch rod 802 is in an inverted L shape, and the second end of the grounding branch rod 802 is arranged downward. A plurality of grounding branch rods 802 are arranged, and the plurality of grounding branch rods 802 are arranged at intervals around the grounding main rod 801. In this embodiment, seven grounding branch rods 802 are taken as an example. The second end of the grounding branch rod 802 is coaxially threadedly connected to the telescopic grounding rod 803, and the telescopic grounding rod 803 is arranged one-to-one with the grounding branch rod 802. The telescopic grounding rod 803 extends downward and penetrates the support plate 804. The driving mechanism 9 is used to drive the telescopic grounding rod 803 to rotate.

[0039] Specifically, the grounding rod 802 is provided with a vertically arranged internal threaded hole, the outer circumference of the telescopic grounding rod 803 is provided with an external thread, the telescopic grounding rod 803 is threadedly connected in the threaded hole of the grounding rod 802, and when the telescopic grounding rod 803 rotates, the telescopic grounding rod 803 partially extends out of or retracts from the threaded hole. Of course, in some other embodiments, the threaded hole can also be provided on the telescopic grounding rod 803, and the thread is arranged on the outer circumference of the grounding rod 802, so that the second end of the grounding rod 802 is threadedly connected in the threaded hole of the telescopic grounding rod 803, and when the telescopic grounding rod 803 rotates, the telescopic grounding rod 803 moves up and down relative to the grounding rod 802. A connecting rod 8021 is also arranged on the grounding branch rod 802. Multiple connecting rods 8021 are arranged corresponding to the grounding branch rods 802, and the first end of the connecting rod 8021 is welded and fixed to the side wall of the second end of the supporting branch rod. The second end of the connecting rod 8021 is welded and fixed to the support plate 804. The grounding branch rod 802 is supported by the connecting rod 8021 to improve the connection stability of the grounding branch rod 802.

[0040] It should be noted that when using the lightning protection device of the present invention, the operator needs to first fix the grounding device 8 to the ground. The specific operation is to drive the telescopic grounding rod 803 to rotate through the driving mechanism 9, so that the telescopic grounding rod 803 extends from the grounding branch rod 802 and is vertically inserted into the soil, thereby fixing the entire grounding device 8 stably on the ground, so that the current can be smoothly discharged into the ground. It should be noted that the lower end of the telescopic grounding rod 803 is arranged with a tip, which is conducive to reducing the resistance of the telescopic grounding rod 803 inserted into the soil; in addition, the thread on the outer surface of the telescopic branch rod has a spiral guiding effect on its own insertion into the soil while being threadedly connected with the grounding branch rod 802. The telescopic grounding rod 803 can be inserted into the soil by rotating it without applying vertical pressure. The grounding device 8 of the present invention is equidistantly provided with a number of annularly dispersed grounding rods 802 and telescopic grounding rods 803. The telescopic grounding rods 803 inserted into the soil are dispersedly arranged, and their contact area with the ground is distributed in a dot-net pattern. Therefore, in actual use, the dispersed arrangement of the grounding rods 802 and the telescopic grounding rods 803 expands the contact area between the grounding device 8 and the ground and forms a dot-net pattern, which helps to improve its grounding efficiency and reduce the grounding resistance. The dot-net-shaped telescopic grounding rods 803 can disperse the current more evenly and reduce the current density, thereby improving the grounding effect and safety. In addition, through the dispersed support of multiple grounding rods 802 and telescopic grounding rods 803, the entire grounding device 8 is more stable in the soil and can withstand greater mechanical pressure and environmental stress. The design of the telescopic grounding rod 803 allows the equipment to adapt to soils of different depths and different types of geological structures, ensuring effective grounding in a variety of environments.

[0041] As a preferred embodiment, the driving mechanism 9 includes a driving gear 901, a transmission toothed disc 902, a driven gear 903 and a support seat 904. The first end of the driving gear 901 is rotatably connected to the grounding main rod 801, and the axial direction of the driving gear 901 is perpendicular to the axial direction of the grounding main rod 801. The support seat 904 is fixedly connected to the support plate 804, and the second end of the driving gear 901 is rotatably connected to the support seat 904; the transmission toothed disc 902 is coaxially rotatably connected to the outer wall of the grounding main rod 801, and the transmission toothed disc 902 is provided with circumferential side teeth and end face teeth, the driving gear 901 meshes with the end face teeth of the transmission gear disc 902, and the driven gear 903 meshes with the circumferential side teeth of the transmission gear disc 902; the driven gear 903 is rotatably connected to the support plate 804, the driven gear 903 and the telescopic grounding rod 803 are arranged coaxially one by one, a sliding groove 8031 ​​is provided on the outer wall of the telescopic grounding rod 803 along its own axial direction, a protrusion is provided on the driven gear 903, the protrusion is embedded in the sliding groove 8031, and the telescopic grounding rod 803 is arranged through the driven gear 903. The ratio of the number of teeth of the driving gear 901 to the number of teeth of the end teeth of the transmission gear plate 902 is greater than the number of teeth of the driven gear 903 to the number of teeth of the peripheral teeth of the transmission gear plate 902, so that the rotation speed of the driving gear 901 slows down after being transmitted to the driven gear 903, and the rotational torque increases, thereby increasing the torque of the driven gear 903 and the telescopic grounding rod 803, so that the telescopic grounding rod 803 can adapt to harder soil layers; at the same time, only a smaller force is needed to drive the driving gear 901 to rotate, which is more labor-saving.

[0042] The driving mechanism 9 also includes a power source 905, a reduction assembly 906 and a clutch 907. The reduction assembly 906 is installed on the support plate 804. The output end of the power source 905 is connected to the input end of the reduction assembly 906. The output end of the reduction assembly 906 is connected to the second end of the driving gear 901 through the clutch 907. The driving mechanism 9 also includes a handwheel 908, which is coaxially fixedly connected to the second end of the driving gear 901.

[0043] Specifically, a ring groove is provided at the lower part of the driven gear 903, and a ring slider is provided on the upper surface of the support plate 804 corresponding to the driven gear 903. The driven gear 903 is rotatably connected to the ring slider through the ring groove. When the rotating gear plate rotates, the driven gear 903 is driven to rotate, and when the driven gear 903 rotates, the telescopic grounding rod 803 is driven to rotate. When the telescopic grounding rod 803 rotates, it extends or retracts from the grounding branch rod 802. When the telescopic grounding rod 803 needs to be inserted into the soil, the driven gear 903 is rotated to drive the telescopic grounding rod 803 to extend from the grounding branch rod 802 and insert into the soil.

[0044] It should be noted that, after placing the grounding device 8 at the designated ground location, the operator can first make the tip of the telescopic grounding rod 803 contact the ground, and then manually drive the hand wheel 908 to rotate, thereby driving the driving gear 901 to rotate. When the driving gear 901 rotates, it simultaneously drives multiple driven gears 903 to rotate through the transmission gear plate 902, thereby simultaneously driving multiple telescopic grounding rods 803 to extend from the grounding branch rods 802 and insert into the soil until reaching a suitable depth, thereby completing the fixed installation of the grounding device 8.

[0045] It should be noted that when the hand wheel 908 is manually driven to rotate, the clutch 907 is in a disconnected state. When the insertion depth is deep, it can be driven by a driving source. In this embodiment, the driving source is a motor, and the reduction assembly 906 is a worm gear reducer. The worm is rotatably connected to the support plate 804, and the worm wheel is rotatably connected to the clutch 907. The clutch 907 is coaxially fixedly connected to the second end of the driving shaft. The output end of the motor is coaxially fixedly connected to the worm. When the motor is needed to drive, the clutch 907 is turned on, that is, the worm wheel and the driving gear 901 are locked by the clutch 907, so that the driving gear 901 is driven to rotate when the worm wheel rotates. The rotation of the motor drives the worm to rotate, and the worm drives the worm wheel to rotate, and then drives the driving gear 901 to rotate through the clutch 907, and drives the driven gear 903 to rotate through the transmission gear plate 902, and then drives the telescopic grounding rod 803 to be inserted downward into the soil layer.

[0046] It is worth noting that in some embodiments, a motor may not be used, but an interface may be provided, such as a hexagonal groove is provided at the upper end of the worm shaft. When the worm needs to be driven to rotate, a manual tool can be inserted into the hexagonal groove on site to drive the worm to rotate. The manual tool can be a hexagonal prism rod installed on a hand drill. By inserting the hexagonal prism rod into the hexagonal groove, the worm can be driven to rotate by starting the hand drill. After the installation is completed, the manual tool can be removed. Unlike installing a motor, the manual tool can also be used in other combined lightning protection equipment, saving resources and reducing the cost of production.

[0047] As a preferred embodiment, the grounding device 8 also includes a protective cover 805, which is fixedly connected to the support plate 804. The protective cover 805 is used to protect the driving mechanism 9. It should be noted that the driving source is detachably connected to the protective cover 805, and the output shaft of the driving source passes through the protective cover 805 and is coaxially connected to the worm gear.

[0048] As a preferred embodiment, the mounting frame 1 includes a support rod 101, an upper fixing plate 102, a lower fixing plate 103, a clamping ring 104 and a compression spring member 105. The upper end of the support rod 101 is welded with the upper fixing plate 102, and the lower end is welded with the lower fixing plate 103. The surfaces of the upper fixing plate 102 and the lower fixing plate 103 are both provided with through holes. The inner walls of the through holes on the surfaces of the upper fixing plate 102 and the lower fixing plate 103 are both welded with one end of the compression spring member 105, and the other end of the compression spring member 105 is welded with the clamping ring 104. It should be noted that the operator needs to first The top and bottom ends of the lightning rod 2 are respectively vertically inserted into the upper fixing plate 102 and the lower fixing plate 103, so that the top outer wall and the bottom outer wall of the lightning rod 2 can contact the clamping ring 104 provided in the upper fixing plate 102 and the lower fixing plate 103 respectively, and push the clamping ring 104 to both sides, so that the compression spring member 105 welded thereto is squeezed and shortened, thereby expanding the distance between the clamping rings 104 on both sides so that it can fully accommodate the entire lightning rod 2. At the same time, the compression spring member 105 will push the connected clamping ring 104 in the reverse direction so that its inner wall can be tightly pressed. The upper fixing plate 102 and the lower fixing plate 103 are closely fitted to the outer walls of the two sides of the lightning rod 2, thereby realizing the fixed installation of the lightning rod 2. In actual use, the upper fixing plate 102 and the lower fixing plate 103 are mechanically fixed by the clamp ring 104 and the compression spring member 105 to ensure that the lightning rod 2 can remain stable when subjected to external forces during use. The design of the mounting frame 1 allows the lightning rod 2 to be quickly disassembled when maintenance or replacement is required, which is convenient for inspection and maintenance. The compression spring member 105 applies pre-pressure to ensure that the clamp ring 104 is in close contact with the lightning rod 2, thereby reducing the lightning rod. 2 may produce vibration and displacement during operation, and the safety of the lightning rod 2 in adverse weather conditions is increased through stable mechanical fixation and pre-pressure of the compression spring member 105. At the same time, the design of the compression spring member 105 allows the clamp ring 104 to expand the spacing when the lightning rod 2 is inserted, and after installation, the clamp ring 104 can be pushed back by the rebound property to fit the lightning rod 2 tightly, thereby providing a certain degree of adjustability and being able to adapt to lightning rods 2 of different sizes. The support rod 101 provides additional structural support to ensure the stability of the entire lightning rod 2 device in the vertical direction.

[0049] As a preferred embodiment, the protective mechanism 10 includes a first protective shell 1001, a second protective shell 1002, a mounting screw plate 1003, a slot 1004 and an insertion strip 1005. The first protective shell 1001 and the second protective shell 1002 are both provided with mounting screw plates 1003 at the upper and lower ends, and the surface of the mounting screw plates 1003 is provided with screw holes.
