Figure 9 DETAILED DESCRIPTION

[0018] The application will be further described in detail below in combination with the drawings.

[0019] As Figures 1-9 ​As shown, the application discloses a kind of anti-dancing spacer for high-voltage transmission tower system, including the center support 1 of one character or star, the center support 1 is hollow structure, the center support 1 is provided with multiple cylinder bodies 11 radially arranged along its center, the inner end of all cylinder bodies 11 is connected together, its inner cavity is interconnected, the outer end of cylinder body 11 is provided with through hole 11a in the center, further including magnet flexible buffer structure 2, magnet flexible buffer structure 2 includes magnetic cylinder 21, telescopic support rod 22, the inner end of telescopic support rod 22 is inserted into cylinder body 11 through through hole 11a and connects the outer end of magnetic cylinder 21, magnetic cylinder 21 is slidably arranged in cylinder body 11, the inner end of magnetic cylinder 21 in each cylinder body 11 is same in polarity, and the outer end of telescopic support rod 22 is fixedly connected with corresponding high-voltage conductor 3.

[0020] Magnetic cylinder 21 and telescopic support rod 22 can slide along the direction of its corresponding cylinder body 11 inside and outside.

[0021] The center support 1 is one character, and only two cylinder bodies 11 and telescopic support rods 22 are used for spacing support between two high-voltage conductors 3.

[0022] Magnetic cylinder 21 is made of magnet material.

[0023] When the center support 1 is star-shaped, it can be 3, 4, 6 or 8 cylinder bodies 11 and telescopic support rods 22, when there are 3 cylinder bodies 11, the 3 cylinder bodies 11 are arranged in star shape with an included angle of 120 degrees, when there are 4 cylinder bodies 11, the 4 cylinder bodies 11 are arranged in star shape with an included angle of 90 degrees, and so on.

[0024] When the outer end of telescopic support rod 22 is connected to the corresponding high-voltage conductor 3, the inner end of each magnetic cylinder 21 is given an outward pre-tension due to the mutual repulsion of the same poles. When the high-voltage conductor 3 is blown by the wind, the two high-voltage conductors 3 will approach each other, at which time the same poles of the magnetic cylinder 21 repel each other, preventing the two high-voltage conductors 3 from further approaching each other, achieving spacing effect and reducing dancing effect. Since the repulsive force increases gradually as the distance between the two magnetic cylinders 21 decreases, the repulsive force is flexible, reducing the stress concentration caused by the use of rigid support spacer when the high-voltage conductor 3 is blown by the wind, avoiding metal fatigue fracture at the rigid connection part during the process of violent and repeated dancing of the high-voltage conductor 3, and prolonging the service life of the high-voltage conductor 3.

[0025] As shown in Figure 1 and Figure 5 The cylinder body 11 is sleeved with a power generation induction coil 4, and the outer end of the magnetic cylinder 21 is inserted into the power generation induction coil 4. The power generation induction coil 4 is connected with a power supply collection circuit, the power supply collection circuit is a battery or a super capacitor charging, and the battery or super capacitor supplies power to the electric equipment through a power module. The power module is a mature technology, and its circuit diagram is omitted.

[0026] The outer end of the magnetic cylinder 21 is inserted into the power generation induction coil 4. When the high-voltage wire 3 is blown by the wind and dances, the magnetic cylinder 21 is driven to slide through the telescopic support rod 22, the length of the magnetic cylinder 21 inserted into the power generation induction coil 4 changes, the magnetic flux passing through the power generation induction coil 4 changes, and the induced current is generated in the power generation induction coil 4. The induced current is collected by the power supply collection circuit and charges the battery or super capacitor. The battery or super capacitor supplies power to the power consumption equipment through the power supply module. The power consumption equipment includes a controller, a motor drive module, a drive motor 71, a wireless communication module, a camera 121, a temperature and humidity sensor, a wind speed and direction sensor, etc.

[0027] Figure 5 The primary side of the transformer T1 is connected to the power generation induction coil 4, which plays a role in boosting the output voltage of the power generation induction coil 4. The bridge rectifier circuit D1 converts the secondary side current of the transformer T1 into direct current, and the voltage stabilizing tube D3 (model 7824) stabilizes the output direct current voltage to the battery or super capacitor.

[0028] As shown in Figure 7 and Figure 8 , preferably, the power supply collection circuit charges the battery or super capacitor through the normally open switch of the first relay J1, and further includes a power supply power detection circuit.

The controller controls the on-off of the coil of the first relay J1. The power supply collection circuit supplies power to the consumption resistor through the normally open switch of the second relay J2. The controller controls the on-off of the coil of the second relay J2. The power supply power detection circuit uses existing mature technology, and its circuit diagram is omitted.

[0029] When the controller controls the coil of the first relay J1 to be powered on, the normally open switch of the first relay J1 is closed, and the power supply collection circuit charges the battery or super capacitor through the normally open switch of the first relay J1. The dancing energy of the high-voltage wire 3 is converted into electrical energy and stored.

[0030] When the battery or super capacitor is full through the power supply power detection circuit, the controller controls the coil of the first relay J1 to be powered off, the normally open switch of the first relay J1 is opened, and the power supply collection circuit stops charging the battery or super capacitor. The controller controls the coil of the second relay J2 to be powered on, and the normally open switch of the second relay J2 is closed. The power supply collection circuit supplies power to the consumption resistor, and the consumption resistor is used to consume the excess electrical energy, that is, the dancing energy of the high-voltage wire 3 is converted into heat energy and consumed.

[0040] Due to the terrain position, wind speed and direction, the installation position of the spacer rod may not be at the maximum dancing position of the high-voltage conductor 3, the existing installation position of the spacer rod is fixed, and it is not convenient to adjust the support position after installation; or due to the need for high-voltage conductor 3 line inspection, the high-voltage conductor 3 line fault is observed by installing a camera 121, the spacer rod needs to be moved; in order to solve the above technical problems, a walking clamping mechanism 7 needs to be installed on the spacer rod, which can walk along the high-voltage conductor 3, move to the maximum dancing position of the high-voltage conductor 3, and increase the effect of resisting dancing; or the camera 121 is installed on the spacer rod and walks along the high-voltage conductor 3, which is convenient for observing the fault state of the line.

When the worm 731 is stationary, the gear 732 is locked and cannot rotate at will, preventing the spacer rod from moving at will.

[0043] Walking wheel Figure 1 And Figure 2None of them are shown, driven by the worm wheel 732, when rotating, with the spacer bar on the high-voltage conductor 3.

[0044] Wherein the single-chip microcomputer adopts STM32F301 and the like, the motor driving module adopts DM542 driver, the driving motor 71 adopts UB57D24-D42-478 stepping motor, and the circuit diagrams of the motor driving module and the stepping motor are omitted.

The detection slip ring (81) is connected to the outer wall of the fixed cover (61) through a return spring (82). The return spring (82) is sleeved on the high-voltage conductor (3). A magnetic ring (84) is provided inside the slip ring (81) or on its outer wall. The inner wall of the fixed cover (61) is provided with a dry ring that cooperates with the magnetic ring (84). An alarm device (83) is installed on the inner wall of the reed tube (85) and the fixed cover (61). The reed tube (85) controls the power supply of the alarm device (83). The detection slip ring (81) slides along the high-voltage wire (3) under the drive of the walking clamping mechanism (7). When the detection slip ring (81) touches the broken wire (3a) of the high-voltage wire (3), it is blocked and stops moving. The detection slip ring (81) compresses the reset spring (82) to make the magnetic ring (84) approach the reed tube (85). The reed tube (85) closes to power the alarm device (83) and emit an alarm signal.
