The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] In Embodiment 1 of this application, as Figures 1 to 3 The wireless power transmission device using composite insulators, as shown, includes an insulator body 1, a power-collecting connection assembly, and a power-receiving connection assembly. A first fitting 2 is provided at one end of the insulator body 1, and a second fitting 3 is provided at the other end.

The power-collecting connection assembly includes a power-collecting bracket 6 and a power-collecting cable 7 mounted on the power-collecting bracket 6. The power-collecting bracket 6 is detachably mounted on the first fitting 2, and one end of the power-collecting cable 7 is connected to an external overhead power transmission line. The wiring connection includes a power receiving cable 7, one end of which is connected to a coil body 5 within a coil plate 4 at one end of the insulator body 1. The power connection assembly comprises a power receiving bracket 8, a power receiving cable 9, and an energy storage device 10. The power receiving cable 9 is mounted on the power receiving bracket 8, which is detachably mounted on the second fitting 3. One end of the power receiving cable 9 is connected to the coil body 5 within a coil plate 4 at the other end of the insulator body 1, and the other end of the power receiving cable 9 is connected to the input terminal of the energy storage device 10. The output terminal of the energy storage device 10 is used to connect to external electrical equipment. The input terminal of the energy storage device 10 is also connected to a voltage regulator circuit, and the other end of the power receiving cable 9 transmits electrical energy to the energy storage device 10 for storage via the voltage regulator circuit.

[0025] Specifically, this utility model features a novel structure and ingenious design. By arranging multiple coil plates 4 with embedded coils at intervals along the length of the insulator body 1, a distributed magnetic resonance coupling path is formed, enabling non-contact energy transmission from the high-voltage side to the low-voltage side. Simultaneously, it maintains the mechanical support and electrical isolation functions of traditional insulators. This utility model integrates insulator functionality with wireless power transmission technology, providing reliable power supply for line monitoring devices (such as cameras, sensors, and inspection drones). It solves the problems of frequent battery replacements, weather-dependent power supply stability, or limited power output associated with traditional power supply methods using batteries, solar power, or wind power generation devices. The power take-up and connection components adopt a modular design to support quick assembly and disassembly, facilitating maintenance or replacement. Simultaneously, stable power input / output transmission is achieved through cable connections. Furthermore, the connection component integrates a voltage regulator circuit to optimize the input stability of the energy storage device 10.

[0026] In this embodiment, the coil board 4 includes an epoxy base plate 11, thermal adhesive, a coil body 5 disposed on the epoxy base plate 11, and a capacitor disposed on the epoxy base plate 11. The thermal adhesive is used to cover the coil body 5 and the capacitor on the epoxy base plate 11. The coil body 5 is adhered to the epoxy base plate 11 by epoxy resin. The capacitor is adhered to the epoxy base plate 11 by epoxy resin. Specifically, the coil board 4 uses an epoxy base plate 11 to encapsulate the coil and capacitor, combined with thermal adhesive coverage, to balance electromagnetic performance and heat dissipation requirements; the epoxy resin adhesion enhances structural stability and prevents components from detaching due to high-frequency vibration.

[0027] In this embodiment, the power supply bracket 6 includes a first mounting plate 12 and a second mounting plate 13 arranged opposite each other. The first mounting plate 12 has a first semi-circular groove 14 on its inner side, and the second mounting plate 13 has a second semi-circular groove 15 on its inner side. The first mounting plate 12 and the second mounting plate 13 are detachably connected. When the first mounting plate and the second mounting plate 13 are connected, the first semi-circular groove 14 and the second semi-circular groove 15 are fitted onto the first fitting 2. The first mounting plate 12 has first limiting posts 18 at both ends of its inner side, and a first limiting elastic ball 19 at the front end of each first limiting post 18. The second mounting plate 13 has two first insertion holes 20 at both ends of its inner side. The first limiting posts 18 are correspondingly positioned to the first insertion holes 20, and the first limiting elastic ball 19 is tightly abutted against the outer wall of the second mounting plate 13. Specifically, the power supply bracket 6 adopts a split mounting plate structure, namely the first semi-circular groove 14 structure of the first mounting plate 12 and the second semi-circular groove 15 structure of the second mounting plate 13. After being fitted onto the outer periphery of the first hardware 2, it is then inserted into the first socket 20 through the first limiting pin 18. When the first limiting pin 18 passes through the first socket 20, the first limiting elastic ball 19 deforms until it completely passes through the first socket 20 and then returns to its original shape. This allows the first limiting elastic ball 19 to be locked on the outside of the second mounting plate 13, thus locking the first limiting pin 18 and the first socket 20. This ensures a tight and fixed connection between the power supply bracket 6 and the first hardware 2, preventing loosening. The first limiting elastic ball 19 and the first socket 20 cooperate to form a self-locking mechanism, which can be fixed without additional tools. The operation is simple and suitable for high-altitude working environments.

[0029] In Embodiment 2 of this application, the power connection bracket 8 includes a third mounting plate 16 and a fourth mounting plate 17 arranged opposite each other. The inner side of the third mounting plate 16 has a third semi-circular groove, and the inner side of the third mounting plate 16 has a fourth semi-circular groove. The third mounting plate 16 and the fourth mounting plate 17 are detachably connected. When the third mounting plate and the fourth mounting plate 17 are connected, the third semi-circular groove and the fourth semi-circular groove are fitted onto the second fitting 3. The inner ends of the third mounting plate 16 are respectively provided with second limiting posts, and the front end of each second limiting post is provided with a second limiting elastic ball. The inner ends of the fourth mounting plate 17 are respectively provided with two second insertion holes. The second limiting posts are correspondingly arranged with the second insertion holes, and the second limiting posts are inserted into the second insertion holes. The second limiting elastic balls are in close contact with the outer wall of the fourth mounting plate 17. Specifically, the connection method between the third mounting plate 16 and the fourth mounting plate 17 is equivalent to the connection method between the first mounting plate 12 and the second mounting plate 13 in Embodiment 1, which will not be described in detail here. It is mainly to facilitate the quick disassembly and installation between the third mounting plate 16 and the fourth mounting plate 17.
