[0002] Distribution network refers to the power grid lines that receive electric energy from the transmission network or regional power plant, and distribute it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles and towers, distribution transformers, disconnectors, reactive power compensators and some ancillary equipment. The installation of distribution network lines is becoming more and more common. Distribution network lines cross roads, iron bridges, rivers, buildings, etc. Their safety is threatened by illegal construction, illegal buildings, illegal trees, etc. Distribution network lines are easily damaged by external forces. When distribution lines are hit, tripping and power outages will occur, which will not only cause loss of life and property to the units and individuals involved, but also have a serious impact on the safe production of the power supply department. The occurrence of external force damage incidents is characterized by regularity, concealment and suddenness.
[0003] However, most of the existing external breach warning devices are camera monitoring or manual inspection, which have the following problems: 1. The monitoring angle is fixed and the monitoring range is limited. It is impossible to flexibly set the monitoring position according to the actual situation and flexibly respond to changes in external breach scenes; 2. After the video surveillance is put into use, external breach warning requires manual monitoring and screening, the actual operation efficiency is too low, and it is difficult to locate after the external breach, and it lacks flexibility; 3. Manual inspection, the inspection process wastes a lot of manpower and material resources, and the problem positioning is time-consuming and not real-time.

[0025] In order to make the contents of the present invention easier to understand, the technical solution of the present invention is further described below in conjunction with specific implementation methods and drawings, but the present invention is not limited thereto.
[0026] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: an intelligent distribution network external damage warning device, including a box body 1, a power supply module 2 is arranged in the box body 1, the output end of the power supply module 2 is connected to the Raspberry Pi mainboard 3, the output end of the Raspberry Pi mainboard 3 is connected to the communication module 4, a microphone 5 is fixedly arranged on the box body 1, the output end of the microphone 5 is connected to the Raspberry Pi mainboard 3, a support rod 6 is detachably arranged at the bottom of the box body 1, and a triangular support mechanism 7 is arranged on the outer sliding sleeve of the support rod 6.
[0027] As a further preference of this embodiment, the microphone 5 is connected to the Raspberry Pi mainboard 3 via a USB interface; the power supply module 2 is a 5V power supply, connected to the Raspberry Pi mainboard 3 via a Type-C interface, and is responsible for powering the Raspberry Pi mainboard 3; the communication module 4 is a 4G communication module, connected to the RXD pin and TXD pin of the GPIO wiring port in the Raspberry Pi mainboard 3 via TXD and RXD leads, and is responsible for transmitting the early warning results to the server. By using a 4G module for transmission, the problem of the original transmission requiring WiFi is solved, and the environmental compatibility of the device is greatly improved.
[0028] From the above description, it can be seen that the audio data around the distribution network device is collected by the microphone 5, and the audio data is transmitted to the Raspberry Pi mainboard 3. The audio is automatically recorded and analyzed by the Raspberry Pi mainboard 3, and the prediction result is obtained. If it is a construction machine that may cause damage to the cable, the warning result is transmitted to the server warning under the action of the communication module 4.
[0029] As a further preference of this embodiment, the support rod 6 is a cavity structure, a positioning rod 61 is fixedly provided inside the support rod 6, a clamping rod 62 is rotatably connected to the positioning rod 61, a pressing block 63 is fixedly provided at the top end of the clamping rod 62, a clamping block 64 is fixedly provided at the bottom end of the clamping rod 62, the pressing block 63 and the clamping block 64 are respectively arranged on both sides of the clamping rod 62, a first opening 65 for pressing the pressing block 63 is opened on the circumferential surface of the support rod 6, a second opening 66 is opened on the side of the support rod 6 opposite to the first opening 65, and the clamping block 64 passes through the second opening 66.
[0030] As a further preference of this embodiment, a horizontally placed spring 67 is arranged in the support rod 6, and the spring 67 and the block 64 are respectively arranged on both sides of the clamping rod 62, one end of the spring 67 is fixedly connected to the bottom end of the clamping rod 62, and the other end of the spring 67 is fixedly connected to the inner wall of the support rod 6.
[0031] As a further preferred embodiment of this embodiment, a conical block 68 is fixedly provided at the bottom end of the support rod 6 .
[0032] From the above description, it can be seen that when the early warning device needs to be driven into the ground, by pressing the pressing block 63, the clamping rod 62 rotates around the hinge point with the positioning rod 61, and the clamping block 64 moves into the support rod 6. Under the action of the conical clamping block 68, the device is pressed down to a certain depth, and then the pressing block 63 is released. Under the resetting action of the spring 67, the clamping block 64 is stuck in the soil to fix the support rod 6.
[0033] See also Figure 4 The triangular support mechanism 7 includes a support ring 71 which is slidably connected to the circumferential outer wall of the support rod 6, and an arc-shaped fixing block 72 is symmetrically arranged in the support ring 71. The outer ends of the arc-shaped fixing block 72 are respectively provided with waist-shaped grooves, and screws 73 are movably connected in the waist-shaped grooves. Corresponding threaded holes are provided on the support ring 71, and the screws 73 penetrate the support ring 71 and are threadedly connected to the threaded holes. An adjustment handle 74 is fixedly arranged on the outer side of the screw 73.
[0034] As a further preferred embodiment of this embodiment, the support ring 71 is composed of two half rings hinged to each other, and the free ends of the two half rings are fixedly connected by bolts.
[0035] As a further preference of this embodiment, three supporting feet 75 are arranged in an array on the circumferential outer wall of the arc-shaped fixing block 72. The supporting feet 75 may be fixed on the circumferential outer wall of the arc-shaped fixing block 72, or may be hinged to the circumferential outer wall of the arc-shaped fixing block 72. If the supporting feet 75 are hinged to the circumferential outer wall of the arc-shaped fixing block 72, the friction between the supporting feet 75 and the arc-shaped fixing block 72 may support the entire device, and a certain amount of force is required when adjusting the supporting feet 75.
[0036] From the above description, it can be known that when in use, the support ring 71 is detachably connected to the support rod 6. When the support ring 71 is moved to a suitable position, the adjustment handle 74 is rotated in sequence, and the screw 73 moves in the corresponding waist-shaped groove, so that the inner walls of the arc-shaped fixing blocks 72 on both sides are tightly attached to the corresponding support rod 6. Therefore, the inner diameter size between the arc-shaped fixing blocks 72 on both sides can be adjusted according to the size of the support rod 6, which has stronger adaptability and enables the support ring 71 to move up and down on the support rod 6 and be fixed on the support rod 6.
[0037] As a further preference of this embodiment, a solar panel 8 is fixedly arranged on the top of the box body 1 , and the solar panel 8 is electrically connected to the power supply module 2 , and the power supply module 2 can be charged through the solar panel 8 .
[0038] The working principle of this utility model:
[0039] See also Figure 6 When the device needs to be used temporarily or the road surface is a cement road and it is difficult to drill holes, there is no need to insert the support rod 6 into the ground. The height of the support ring 71 can be adjusted directly so that the three support feet 75 support the early warning device and place it firmly on the ground.
[0040] See also Figure 5 If the soil is soft or the early warning device needs to be fixed for a long time, the pressing block 63 is pressed to rotate the clamping rod 62 around the hinge point with the positioning rod 61, and the clamping block 64 moves into the support rod 6. Under the action of the conical clamping block 68, the device is pressed down to a certain depth, and then the pressing block 63 is released. Under the reset action of the spring 67, the clamping block 64 is clamped into the soil to fix the support rod 6. The clamping block 64 is clamped in the soil by the elastic force and the lever, and then the height of the support ring 71 is adjusted so that the support foot 75 on the ground can be adjusted to the nearby Figure 5 This ensures that the warning device is stable both up and down as well as left and right.
[0041] The device can be flexibly and quickly installed at high-incidence accident points, automatically monitor the working sounds of large construction equipment nearby, and issue early warnings for all potential equipment threats to ensure the safety of the distribution network, especially for underground cables. Taking into account the different geology near the cables and rapid installation, the utility model realizes rapid and stable installation and disassembly by designing labor-saving levers, clamping blocks 64, etc., and realizes the stability of the device in different environments through the liftable triangular support mechanism 7.
