[0030] The mounting frame forms a detection port facing toward or away from the power transmission line, the infrared detection component 2 is arranged on the mounting frame, and the infrared detection component 2 forms at least two infrared detection optical paths distributed in the vertical direction at the detection port;

[0031] The infrared detection component 2 is provided with an alarm component 7 , and the infrared detection component 2 is remotely connected to the wireless receiving device for communication, and the energy supply component 1 is electrically connected to the infrared detection component 2 .

[0032] From the above description, it can be seen that the beneficial effects of the utility model are: providing a height limit trigger warning linkage device for preventing external damage to transmission lines, setting on-site warning devices on both sides of the transmission line anti-external damage corridor, and detecting whether there are moving objects passing through the detection port through the infrared detection optical path formed by the infrared detection component 2 to prevent objects from getting too close to the transmission line. When multiple optical paths detect that an object has passed, an alarm is triggered and a notification is sent to the wireless receiving device in time to remind the operator to come and deal with it; multiple infrared detection optical paths are set to avoid false triggering of alarms due to accidental touches by animals such as birds, thereby providing reliable real-time protection for transmission lines and improving the timeliness of external damage warnings.

[0033] Furthermore, the infrared detection component 2 includes at least two infrared emitting elements 21 and at least two infrared receiving elements 22;

[0034] The infrared emitting element 21 and the infrared receiving element 22 are relatively arranged at positions on the mounting frame corresponding to the two sides of the detection port, and the positions of the infrared emitting element 21 and the infrared receiving element 22 are adjustable up and down.

[0035] From the above description, it can be seen that multiple sets of infrared emitting elements 21 and infrared receiving elements 22 with adjustable positions are relatively arranged on the mounting frame, so that during on-site installation, adaptive adjustments can be made according to the on-site environment to ensure the accuracy and effectiveness of the detection.

[0036] Further, the mounting frame includes a first column 3 and a second column 4;

[0037] The first column 3 and the second column 4 are arranged opposite to each other, and the infrared emitting element 21 and the infrared receiving element 22 are both arranged on the first column 3 and the second column 4 .

[0038] It can be seen from the above description that the mounting frame is composed of the first column 3 and the second column 4, which occupies a small ground area and is easy to install.

[0039] Further, the first column 3 and the second column 4 each include a telescopic rod and a base;

[0040] The telescopic rod is erected on the base.

[0041] From the above description, it can be seen that by adjusting the length of the telescopic rod, the height of the infrared detection component 2 from the ground during actual installation can be adjusted, making the equipment layout more flexible and more applicable.

[0042] Furthermore, the energy supply component 1 includes a solar power supply panel 11 and a rechargeable battery 12;

[0043] The rechargeable battery 12 is electrically connected to the solar power supply panel 11 and the infrared detection component 2 respectively, and the solar power supply panel 11 is arranged on the top of the mounting frame.

[0044] From the above description, it can be seen that the energy supply component 1 includes a solar power panel 11 and a rechargeable battery 12. During the operation of the equipment, combined with the actual open-air environment of the transmission line, the solar charging function of the solar power panel 11 can be fully utilized, which saves energy and is environmentally friendly, and prolongs the sustainable operation time of the equipment.

[0045] Further, the wireless receiving device includes a remote receiving component 5 and a portable moving component 6;

[0046] The infrared detection component 2 is connected to the remote receiving component 5 and the portable moving component 6 for remote communication respectively.

[0049] A height-limited trigger warning linkage device for preventing external damage to a power transmission line, comprising an on-site warning device and a wireless receiving device; the on-site warning device comprises an energy supply component 1, an infrared detection component 2 and a mounting frame for arrangement at a power transmission line site; a detection port facing toward or away from the power transmission line is formed on the mounting frame, the infrared detection component 2 is arranged on the mounting frame, and the infrared detection component 2 forms at least two infrared detection optical paths distributed in a vertical direction at the detection port; an alarm component 7 is provided on the infrared detection component 2, and the infrared detection component 2 is remotely connected to the wireless receiving device for communication, and the energy supply component 1 is electrically connected to the infrared detection component 2.

[0050] In this embodiment, if Figure 1 As shown, the wireless receiving device includes a remote receiving component 5 and a portable mobile component 6; the infrared detection component 2 is remotely connected to the remote receiving component 5 and the portable mobile component 6 respectively. The operating principle of a height-limited trigger warning linkage device for preventing external damage to a power transmission line is as follows:

[0051] During the early stage of deployment, the on-site early warning devices are arranged on both sides of the anti-external damage corridor, and the infrared detection component 2 is used to form an infrared beam path at the detection port. Preferably, the infrared detection component 2 has a maximum distance of 100m, and the infrared detection component 2 is a 4-beam signal to detect moving infrared objects; and the alarm is only issued when 2 or more signals are triggered at the same time (i.e., large mechanical swing arms swing at the same time), which can prevent animals such as birds from accidentally touching and triggering the alarm. The infrared detection component 2 has its own alarm function, such as buzzer alarm, horn broadcast, etc.

[0052] During operation, when there is ultra-high mechanical construction that endangers the line in the line corridor and touches infrared rays, the infrared detection component 2 will sound an alarm at the construction site, and the alarm signal is transmitted to the remote receiving device 5 and the portable mobile device 6 in a wireless frequency modulation and frequency hopping manner; the portable mobile device 6 is carried by the operators in the nearest construction vehicle. After receiving the alarm information, the operators will go to the scene in time for processing; the remote receiving device 5 has a receiving range of more than 3km, and can be specifically selected as the mobile phone of the operation and maintenance personnel.

[0053] Moreover, a set of wireless sound and light alarm is installed on the construction vehicle with hidden danger of external damage. When the portable mobile part 6 receives the warning signal sent by the on-site warning device, the wireless sound and light alarm immediately activates the sound and light alarm to warn the people in the vehicle.

[0054] In this embodiment, the infrared detection component 2 includes at least two infrared emitting elements 21 and at least two infrared receiving elements 22; the infrared emitting elements 21 and the infrared receiving elements 22 are relatively arranged at positions on both sides of the corresponding detection port on the mounting frame, and the positions of the infrared emitting elements 21 and the infrared receiving elements 22 are adjustable up and down.

[0055] In this embodiment, if Figure 1As shown, the mounting frame includes a first column 3 and a second column 4; the first column 3 and the second column 4 are arranged opposite to each other, and an infrared emitting element 21 and an infrared receiving element 22 are arranged on the first column 3 and the second column 4. The first column 3 and the second column 4 both include a telescopic rod and a base; the telescopic rod is erected on the base.

[0056] In addition, the energy supply component 1 includes a solar power supply panel 11 and a rechargeable battery 12; the rechargeable battery 12 is electrically connected to the solar power supply panel 11 and the infrared detection component 2 respectively, and the solar power supply panel 11 is arranged on the top of the mounting frame.

[0057] In summary, the utility model provides a height-limited trigger warning linkage device for preventing external damage to a power transmission line. On-site warning devices are arranged on both sides of the transmission line anti-external damage corridor. The infrared detection optical path formed by the infrared detection component detects whether there is a moving object passing through the detection port to prevent objects from being too close to the power transmission line. When multiple optical paths detect that an object has passed, an alarm is triggered and a notification is sent to the wireless receiving device in time to remind the operator to come and deal with it. Multiple infrared detection optical paths are arranged, and the positions of the optical paths are adjustable, which is flexible in application to avoid false triggering of the alarm due to accidental touch by animals such as birds. It is solar-powered and has a long continuous working time, thereby providing reliable real-time protection for the power transmission line and improving the effectiveness of the anti-external damage warning.
