DETAILED DESCRIPTION OF THE INVENTION

[0016] The following will elaborate in detail on the specific implementation manners of a power transmission disaster prevention offline pole protection device with reference to the accompanying drawings.

[0017] As Figure 1As shown in the figure, the present invention provides a power transmission disaster prevention offline pole protection device, which includes a power pole 2, a control box 1, a power cross arm 3, an insulator 4 and a line fixing device 5. The control box 1 is installed at the lower end of the power pole 2, and a controller is provided inside the control box 1. The power cross arm 3 is installed at the upper end of the power pole 2. One end of the power cross arm 3 connected to the power pole 2 is installed with the insulator 4, and the insulator 4 is connected to the line fixing device 5 through a connecting wire, and the other end is installed with the line fixing device 5. The power transmission line 10 is installed inside the line fixing device 5, and the controller is connected to the line fixing device 5.

[0018] As Figure 2 shown, the line fixing device 5 includes a housing 6, a fixing terminal 7 and a pressure detection device 9. One end of the housing 6 has a groove, and the groove and the other end of the housing 6 have through holes. The pressure detection device 9 is installed in the groove of the housing 6, and the fixing terminal 7 is placed in the groove.

[0019] According to the above, the fixing terminal 7 has a through hole inside, and an electromagnetic fixing device 8 is installed in the through hole. As Figure 3 shown, the electromagnetic fixing device 8 includes an electromagnetic device 11 and a telescopic rod 12, and the telescopic rod 12 is installed in the electromagnetic device 11.

[0020] According to the above, the pressure detection device 9 includes a detection port, and the detection port is connected to the controller through a connecting wire. The pressure detection device 9 can transmit the detected signal to the controller.

[0021] According to the above, the electromagnetic device 11 includes a power input terminal and a control terminal. The power input terminal is connected to the power supply through a connecting wire, and the control terminal is connected to the controller through a connecting wire, so that the controller can control the operation of the electromagnetic device 11.

[0022] According to the above, the telescopic rod 12 is made of a conductive material, and both ends of the telescopic rod 12 have engaging teeth. One of the engaging teeth is installed with the power transmission line 10, and the other engaging tooth is connected to the connecting line of the insulator 4.

[0023] According to the above, the controller includes a control panel, a control chip, a digital quantity output module and a signal detection module. The control panel can set parameter values for the control chip. The digital quantity output module is connected to the electromagnetic device 11 through a connecting wire, so that the controller can automatically operate the electromagnetic device 11. The signal detection module is connected to the pressure detection sensor through a connecting wire, so that the controller can detect the signal inside the pressure detection device 9.

[0024] The working principle of a power transmission disaster prevention and derailment pole protection device is as follows: one end of the transmission line 10 is passed through the shell 6 of the line fixing device 5 and placed in the fixed terminal 7, and the electromagnetic device 11 is operated by the controller to install the transmission line 10 in the fixed terminal 7. The connecting wire on the insulator 4 is placed in the fixed terminal 7, and the electromagnetic device 11 is operated by the controller to connect the two at the fixed terminal 7. When encountering strong winds, the transmission line 10 is affected by the wind and will deviate in the direction of the strong wind. The fixed terminal 7 in the line fixing device 5 is squeezed in the internal through hole of the shell 6 of the line fixing device 5, and the pressure detection device 9 detects the pressure and transmits the pressure to the control. The upper limit parameter value of the pressure is set in the control. When the pressure detection device 9 detects that the pressure is higher than the parameter value set in the controller, the controller will control the electromagnetic device 11 to operate, so that one end of the transmission line 10 is not fixedly connected in the line fixing device 5, and the transmission line will be separated from the line fixing device 5 under the action of gravity, so as to achieve the effect of derailment pole protection.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention. A person skilled in the art should understand that the specific implementation of the present invention can be modified or replaced by equivalents, but these modifications or changes are within the scope of protection of the pending claims.
