For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] Example 1

[0048] like Figures 1 to 8 As shown, the present application provides an anti-external damage warning device for a rural power grid line, comprising a fixed clamp 1 connected to a pole, a reflective base 2 being obliquely arranged on the fixed clamp 1, a columnar lighting fixture 3 being horizontally extended from the bottom of the reflective base 2, a static width indicating mechanism 4 and a dynamic height indicating mechanism 5 being respectively arranged on the left and right sides of the columnar lighting fixture 3, the static width indicating mechanism 4 and the dynamic height indicating mechanism 5 direct the light of the columnar lighting fixture 3 into their own light-transmitting parts to mark the pole position and the top cable position, and the dynamic height indicating mechanism 5 can also serve as a movable railing.

[0049] A controller is also provided on the reflective base 2, and the controller is electrically connected to the columnar lighting fixture 3, the static width indicating mechanism 4, the dynamic height indicating mechanism 5 and the external image recognition camera.

[0050] Specifically, the columnar lighting fixture 3 includes a lighting portion 31 located in the middle and connecting portions 32 arranged on the left and right sides of the lighting portion 31, and the static width indicating mechanism 4 and the dynamic height indicating mechanism 5 include a first refracting member 43 and a second refracting member 51 movably sleeved on the left and right sides of the columnar lighting fixture 3 respectively;

[0051] The first refraction member 43 and the second refraction member 51 have the same shape, with spherical structures on the left and right sides and a conical structure in the middle with an arc-shaped top and an inner diameter that decreases downward. The inner cavity is coated with a total reflection coating. A width indicator rod 47 is provided at the bottom of the first refraction member 43, and a height indicator rod 52 is provided at the bottom of the second refraction member 51. The first refraction member 43 and the second refraction member 51 respectively guide the light of the columnar lighting fixture 3 into the inner cavities of the width indicator rod 47 and the height indicator rod 52, and the width indicator rod 47 and the height indicator rod 52 are made of translucent material.

[0052] The spherical design on both sides of the first refractive element 43 and the second refractive element 51 can make the light converge toward the middle, and then effectively guide the light into the width indicator rod and the height indicator rod through the conical structure with an arc on the top and an inner diameter that shrinks downward, thereby playing a warning role. The total reflection coating can be an aluminum coating or other metal coating or a nano-ceramic mixed coating, which is not limited in the present application. Preferably, the width indicator rod 47 and the height indicator rod 52 can be painted with color on the outside to enhance the warning effect.

[0053] Specifically, the static width indicating mechanism 4 also includes a displacement guide rail 41 arranged at the bottom of the reflective base 2, and the slider of the displacement guide rail 41 is connected to the first refractive member 43 through a light guide connecting rod 42. A first hollow bracket 431 is arranged on the inner cavity side wall of the first refractive member 43, and a plurality of first supporting slide bars 432 are arranged on the first hollow bracket 431. The first supporting slide bars 432 extend horizontally to the left along the right side wall of the first refractive member 43 and are evenly arranged on the outer periphery of the columnar lighting fixture 3. A plurality of first inner guide slide bars 321 are arranged on the outer periphery of the left side connection part 32 of the columnar lighting fixture 3. The first inner guide slide bars 321 correspond one-to-one with the first supporting slide bars 432 and are slidably embedded in the first supporting slide bars 432.

[0054] In the initial state, the first refraction member 43 is mounted on the left connection portion 32 of the columnar lighting fixture 3. When the external image recognition camera recognizes that a vehicle or a rider is approaching, the displacement guide rail 41 drives the first refraction member 43 to move a preset distance L toward the middle of the columnar lighting fixture 3, so that the lighting portion 31 of the columnar lighting fixture 3 enters the first refraction member 43. The first refraction member 43 guides light into the width indicator rod 47, and the line pole is marked by the vertically arranged and luminous width indicator rod 47 to prevent accidental collision.

[0055] The first hollow bracket 431 and the first supporting slide bar 432 are used for supporting and guiding the movement of the first deflecting member 43 .

[0056] Preferably, a first rotating seat 44 is provided at the bottom of the first refracting member 43, the width indicating rod 47 is rotatably inserted in the first rotating seat 44 and a plurality of shading strips are evenly distributed on its periphery, and a rotation drive mechanism 45 is provided on one side of the width indicating rod 47 for driving the width indicating rod 47 to rotate around its own central axis.

[0057] Furthermore, the rotary drive mechanism 45 includes a mounting bracket connected to the bottom of the reflective base 2, a rotary drive motor is provided at the end of the mounting bracket, a main gear is provided on the output shaft of the rotary drive motor, and a driven gear 46 meshing with the main gear is provided on the outer periphery of the width indicator rod 47.

[0058] The rotary drive motor of the rotary drive mechanism 45 rotates, driving the width indicator rod 47 to rotate through the meshing main gear and the driven gear 46, thereby enhancing the marking effect of the line rod, and the shading strip is used to achieve a visual effect of alternating light.

[0059] Specifically, a second hollow bracket 511 is arranged on the inner cavity side wall of the second refractive member 51, and two rotating rings 513 are rotatably arranged on the second hollow bracket 511. A plurality of second supporting slide bars 512 are arranged on the inner sides of the two rotating rings 513. The second supporting slide bars 512 extend horizontally to the right along the left side wall of the second refractive member 51 and are evenly arranged on the outer periphery of the columnar lighting fixture 3. A plurality of second inner guide slide bars 322 are arranged on the outer periphery of the right side connecting portion 32 of the columnar lighting fixture 3. The second inner guide slide bars 322 correspond one-to-one to the second supporting slide bars 512 and are slidably embedded in the second supporting slide bars 512. The dynamic height indicating mechanism 5 also includes a multi-purpose driving mechanism for driving the second refractive member 51 to slide along the columnar lighting fixture 3 and rotate along the central axis of the columnar lighting fixture 3.

[0060] Furthermore, the multi-purpose driving mechanism includes a driving connecting rod 55 connected to the right side of the end of the height indicator rod 52. The driving connecting rod 55 is L-shaped and the end thereof is rotatably connected to a rotor driving assembly 56.

[0061] In the initial state, the second refraction member 51 is mounted on the right connecting portion 32 of the columnar lighting fixture 3. When the external image recognition camera recognizes that a vehicle or a rider is approaching, the rotor drive assembly 56 drives the second refraction member 43 to move a preset distance L toward the middle of the columnar lighting fixture 3, so that the lighting portion 31 of the columnar lighting fixture 3 enters the second refraction member 51. The second refraction member 51 directs light into the width indicator rod 47, causing the height indicator rod 52 to flash. The rotor drive assembly 56 then drives the height indicator rod 52 to rotate upward to a horizontal position to mark the position of the top cable.

[0062] Preferably, in order to enhance the warning effect, the rotor drive assembly 56 can drive the height indicator rod 52 to move periodically within a preset airspace below the cable.

[0063] The second hollow bracket 511, the rotating ring 513, the second supporting slide bar 512, and the second inner guiding slide bar 322 are used to provide guiding support for the translation and rotation of the second deflecting member 51 on the cylindrical lighting fixture 3. Figure 4 As shown, the second hollow bracket 511 includes two groups of fixed columns arranged vertically, and the rotating ring 513 is rotatably embedded in the opposite end surface of each group of fixed columns.

[0064] Specifically, a connecting seat 551 is provided at the end of the driving connecting rod 55, and a hinge column 552 is vertically provided on the right end surface of the connecting seat 551. A second rotating seat 561 is provided on the left side of the bottom bin of the rotor driving assembly 56. A mounting groove is opened on the second rotating seat 561, and the hinge column 552 is rotatably inserted in the mounting groove. A second clamping mechanism 562 is provided on the side wall of the mounting groove, and the clamping part of the second clamping mechanism 562 is in contact with the peripheral activity of the hinge column 552.

[0065] The articulation of the drive link 5 and the rotor drive assembly 56 facilitates maintaining the stability of the rotor drive assembly 56 during flight. The second clamping mechanism 562 is used to clamp the hinge column 552 when the rotor drive assembly 56 returns to its original position after completing the marking operation, so that the rotor drive assembly 56 is firmly parked on the drive link 55.

[0066] Specifically, the rotor drive assembly 56 may be a multi-rotor UAV.

[0067] Preferably, the dynamic height indicating mechanism 5 can also realize the function of a movable guardrail to physically block passing vehicles. When the external image recognition camera recognizes that the size of the vehicle is larger than the preset size (which will interfere with the top cables or roadside poles), if it is recognized that the distance between the vehicle and the present application is less than the preset distance D-2, the rotor drive assembly 56 first drives the second refractive element 51 to perform the light guiding operation, and then drives the height indicating pole 52 to rotate upward by a preset angle (for example, 45 degrees), so that the height indicating pole 52 is tilted toward the road surface to block the movement of vehicles.

[0068] Furthermore, an inserted railing 54 is movably inserted into the inner cavity of the height indicating pole 52, and a telescopic clutch seat 53 is provided at the bottom end of the height indicating pole 52. The telescopic clutch seat 53 is arranged around the outer periphery of the inserted railing 54 and a first clamping mechanism 531 is embedded in the side wall of its inner cavity. The first clamping mechanism 531 movably interferes with the outer periphery of the inserted railing 54. The inserted railing 54 is provided with an inner cavity whose top is connected with the inner cavity of the height indicating pole 52, and the inserted railing 54 is made of light-transmitting material.

[0069] The inserted guardrail 54 is telescopic along the inner cavity of the height indicator pole 52 to increase its length to enhance the blocking effect when the height indicator pole is used as a movable guardrail. The first clamping mechanism 531 inside the telescopic clutch seat 53 is used to clamp and release the inserted guardrail 54, and cooperate with the rotor drive assembly 56 to realize the telescopic effect of the inserted guardrail 54.

[0070] The structures of the first clamping mechanism 531 and the second clamping mechanism 562 are not limited. Typically, they can be composed of symmetrically arranged telescopic electric cylinders, and the ends of the telescopic electric cylinders are provided with pressure plates that movably interfere with the clamped components.

[0071] A photovoltaic panel 23 is disposed on the top of the reflective base 2 , and a reflective groove 22 is disposed at the bottom of the reflective base 2 at an extended position relative to the columnar lighting fixture 3 . A support rod 21 connected to the columnar lighting fixture 3 is disposed in the reflective groove 22 .

[0072] The present application also provides an energy-saving battery pack, the photovoltaic panel 23 is used to charge the energy-saving battery pack to supply electricity to various components, and the reflective groove 22 is used to enhance the lighting effect of the columnar lighting fixture 3.

[0073] The controller is an industrial computer device, which is fixed to the top of the pole by a fixing clamp 1, and the lighting fixture 3 is arranged along the extension direction of the road surface.

[0074] Based on the above-mentioned rural power line anti-external damage warning device, the present application also provides a rural power line anti-external damage warning method, which specifically includes the following steps:

[0075] S1: The controller receives the recognition alarm signal from the external image recognition camera in real time;

[0076] S2: When it is identified that the distance between the vehicle or rider and the pole is less than the preset distance D-1, the static width indicator and the dynamic height indicator are controlled to indicate the pole position and the cable height position for warning;

[0077] S3: When it is identified that the size of the vehicle is larger than the preset size and the distance from the pole is less than the preset distance D-2, the dynamic height indication mechanism is controlled to act as a movable barrier to block the vehicle.

[0078] The step S2 is applicable to nighttime scenes, and the step S3 is applicable to all-day scenes.

[0079] Preferably, in step S2, the position of the first deflecting member 43 or the second deflecting member 51 on the columnar lighting fixture 3 can be adjusted according to the distance between the vehicle or the rider and the pole to achieve the effect of brightness change and enhance the warning effect.

[0080] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
