Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a high-efficiency distribution network frame structure used for distribution network planning. Background Art

[0002] The distribution network refers to a power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. In the existing power grid architecture, insulators are exposed to the outdoor environment and are easily damaged. In addition, when fixing the wires and insulators, they need to be tied one by one, which is time-consuming and labor-intensive.

[0003] A Chinese patent with authorization announcement number CN115693573B discloses an efficient distribution network rack structure for distribution network planning, which relates to the technical field of power equipment, including an insulator for connecting electric wires, wherein the insulator is provided with at least one heat-conducting sheet inside, and the bottom of the insulator is fixedly embedded with a heat-conducting ring fixedly connected to the top and the bottom of the heat-conducting sheet, and a wire rack for installing the insulator, wherein the wire rack is installed on a utility pole, and the top of the wire rack is provided with at least one connecting column. By arranging the insulator, the wire rack and the protective assembly, the heat-conducting sheet inside the insulator is heated by the heating head, so that the heat-conducting sheet transfers heat to the insulator, so that the insulator can be prevented from being affected by overfreezing in cold weather, and the damage of the insulator caused by sudden cooling and sudden heating is reduced. The protective rack reduces the dust pollution on the insulator and reduces the occurrence of flashover accidents.

[0004] However, the device still has some shortcomings: the protective frame in the device is in an elastically active state, which means that each wire still needs to be independently tied with a cable tie. According to actual conditions, the connection between a single wire and an insulator requires multiple windings, which is time-consuming and labor-intensive. In addition, the device requires improvements to existing power grids and insulators. It cannot be retrofitted to traditional power grids, making it inconvenient to promote. Summary of the invention

[0027] Embodiment 1

[0028] like Figure 1-Figure 6 As shown, the present invention proposes a high-efficiency distribution network frame structure for distribution network planning, including angle steel 1, mounting parts 2, insulators 4, columns 6, photovoltaic panels 10, heating wires 14 and fans 15.

[0029] The angle steels 1 on both sides are connected by the mounting member 2, and the mounting member 2 includes a clamping plate A201 and a clamping plate B202, and the clamping plates A201 and B202 are respectively connected to the corresponding side angle steels 1. Two groups of studs 2011 are symmetrically arranged on the clamping plate A201, and two groups of internal threaded tubes 2021 are symmetrically and rotatably arranged in the clamping plate B202. Each stud 2011 is respectively inserted into the corresponding side internal threaded tube 2021 and threadedly connected thereto, and a driving member for driving each internal threaded tube 2021 to rotate synchronously is arranged in the clamping plate B202. The driving member includes a gear A2022, a gear B2023 and a worm 2025. The gear A2022 is rotatably arranged in the clamping plate B202, and each internal threaded tube 2021 is respectively connected to the corresponding side gear A2022. The gear B2023 is rotatably arranged in the clamping plate B202. The gear B2023 is located between the gears A2022 and meshed with the gears A2022. A worm wheel 2024 is also arranged on the central axis of the gear B2023. The worm wheel 2024 is rotatably connected to the inner wall of the clamping plate B202. The worm 2025 is arranged in the clamping plate B202 and rotatably connected thereto. The worm 2025 is meshed with the worm wheel 2024. One end of the worm 2025 extends out of the clamping plate B202, and a tool groove opening outward is arranged in the end of the worm 2025 extending out of the clamping plate B202. The insulators 4 are evenly arranged on the angle steel 1. The angle steel 1 is provided with a support box 5. The support box 5 is located between two adjacent insulators 4. The column 6 is elastically slidably arranged in the support box 5. A clamping member for limiting the lifting of the column 6 is arranged in the support box 5. The clamping member includes a limit clamping block B601. The limit block B601 is elastically slidably arranged in the column 6, and a number of limit holes B502 are evenly spaced on the support box 5. The limit block B601 is inserted into the corresponding side limit hole B502 and slidably connected thereto. The top of the column 6 is connected to the protective cover plate 8, and two pressure caps 9 are symmetrically arranged at the bottom of the protective cover plate 8. The pressure caps 9 on both sides respectively cooperate with the corresponding side insulators. A cylindrical groove is arranged in the support box 5, and a limit groove 501 connected to the cylindrical groove is arranged on the support box 5. A turntable 7 rotatably connected thereto is arranged at the top of the column 6, and the top of the turntable 7 is connected to the bottom of the protective cover plate 8. The turntable 7 is inserted into the limit groove 501 and meshedly connected thereto.

[0030] The photovoltaic panel 10 is arranged on the protective cover 8, and the protective cover 8 is also provided with a battery assembly 11, and the photovoltaic panel 10 is electrically connected to the battery assembly 11. Two heating chambers 503 are symmetrically arranged in the support box 5, and two air inlet holes 504 are symmetrically arranged on the support box 5. The air inlet holes 504 on both sides are respectively connected to the corresponding heating chambers 503 on the side, and two air outlet holes are symmetrically arranged on the support box 5, and the air outlet holes on both sides are respectively connected to the corresponding heating chambers 503 on the side. The heating wire 14 is arranged in the heating chamber 503, and the fan 15 is arranged in the air outlet. The output ends of the fans 15 on both sides are respectively facing the corresponding side insulators 4, and the battery assembly 11 is electrically connected to each electrical device. A number of partitions 13 are staggered in the heating chamber 503, and a heating channel is arranged between each partition 13. The heating wire 14 is located in the heating channel, and an arc shield 16 is arranged to cover the outside of the air outlet. A temperature detector 12 is disposed at the bottom of the protective cover plate 8 , and a controller is disposed in the support box 5 . The temperature detector 12 is electrically connected to the controller, and the controller controls the connection of the heating wire 14 and the fan 15 .

[0031] In this embodiment, after the grid frame is fixed, the photovoltaic panel 10 receives solar energy and generates electricity, and the electricity is stored in the battery. When the temperature detector 12 detects that the outside temperature is too low, the low temperature signal is fed back to the controller, and the controller controls the heating wire 14 and the fan 15 to start. The outside air enters the heating chamber 503 along the air inlet 504, and the low temperature air exchanges heat with the heating wire 14. The air temperature increases and becomes high temperature hot air. The high temperature hot air is blown toward the insulator 4 under the action of the fan 15, so that the surface temperature of the insulator 4 is increased to prevent freezing. The high temperature hot air can also break the ice that quickly freezes on the surface of the insulator 4 to prevent the electric wire from being involved in the ice when swinging with the wind, thereby causing the insulator to break. The protective cover 8 blocks the falling hail to prevent the hail from directly hitting the insulator 4 and causing the insulator 4 to break. In this device, when the insulator 4 needs to be replaced, it is only necessary to press the limit card block B601. At this time, the column 6 will automatically rise, so that there is enough gap between the pressure cap 9 and the insulator 4 to facilitate the separation of the wires. After the replacement is completed, it is only necessary to press down the protective cover plate 8 to make the pressure cap 9 re-match with the insulator 4 to clamp and fix the wires. At this time, the limit card block B601 will automatically snap into the corresponding side limit hole B502, and the operation is simple and convenient.

[0032] Embodiment 2

[0033] like Figure 1 and Figure 6As shown, the present invention proposes a high-efficiency distribution network frame structure for distribution network planning. Compared with the first embodiment, the angle steels 1 on both sides are connected more strongly by the stopper 3. The stopper 3 includes an outer tube 301 and an inner rod 302. The outer tube 301 and the inner rod 302 are respectively connected to the corresponding side angle steels 1. The inner rod 302 is inserted into the corresponding side outer tube 301 and slidably connected thereto. The outer tube 301 is provided with a plurality of stopper holes A3011 communicating with the interior thereof. The inner rod 302 is elastically slidably provided with a stopper block A3021. The stopper block A3021 is inserted into the corresponding side stopper hole A3011 and slidably connected thereto.

[0034] In this embodiment, the inner rod 302 on one side of the angle steel 1 is inserted into the corresponding outer tube 301 on the inner side of the angle steel 1, so that the angle steels 1 on both sides always remain parallel when approaching each other. When fixing the device on the electric pole, it can be pre-installed at the bottom of the electric pole, and then the pre-installed power grid rack is gradually pulled up. In this process, since the inner rod 302 and the outer tube 301 are in a locked state, the staff only needs to support it slightly to fix the device by rotating the worm 2025. The operation is simple and convenient. At the same time, the limit member 3 can also connect the angle steels 1 on both sides into one, thereby improving the supporting stability of the angle steel 1.

[0035] Embodiment 3

[0036] The present invention also proposes a method for installing an efficient distribution network frame structure for distribution network planning, comprising the following steps:

[0037] S1, the angle steels 1 on both sides, and the clamps A201 and B202 are placed on both sides of the pole respectively, so that the studs 2011 on the clamps A201 are inserted into the corresponding side internal threaded tubes 2021 respectively, and the worm 2025 is driven to rotate by means of a tool, and the worm 2025 is used to drive the worm wheel 2024 and the gear B2023 to rotate, and the gear B2023 synchronously drives the gears A2022 and the internal threaded tube 2021 to rotate, so that the studs 2011 are synchronously penetrated into the corresponding side internal threaded tube 2021, so that the angle steels 1 on both sides are always kept parallel and close.

[0038] S2. Release the restriction of the support box 5 on the column 6, and the column 6 automatically rises to a high position. Place the wire rack in the grooves at the top of the corresponding side insulators 4 on both sides, then press down the column 6, and use the pressure cap to press and fix the wires. At the same time, the column 6 is automatically locked.
