Specifically, the rotary member 326 is eccentrically disposed with respect to the second transmission rod 325. The first transmission rod 322, the first roller 323, the second roller 324 and the second transmission rod 325 are driven to rotate the rotating member 326. Since the rotating member 326 always abuts against the shield cleaning assembly 330, the eccentric rotating member 326 can drive the shield cleaning assembly 330 to move up and down periodically.
Specifically, the diameter of the first rotating wheel 323 is larger than that of the second rotating wheel 324, and when the first rotating wheel 323 is driven by wind power to rotate by a small angle, the second rotating wheel 324 engaged with the first rotating wheel 323 can rotate by a large angle, and the rotating member 326 can rotate to drive the blocking object cleaning assembly 330 to perform more periodic actions, so that wind energy can be fully utilized, and the lens 111 can be cleaned more thoroughly.
More specifically, the driving force transmission assembly 320 further includes a limiting block 327, the limiting block 327 is fixedly connected to the top of the inner side of the casing 321, a rotating groove 328 is formed in the limiting block, and the rotating member 326 can extend into the rotating groove 328, as shown in fig. 4.
Fig. 5 shows a schematic structural diagram of a shelter cleaning assembly of a power distribution network overhead line real-time monitoring device provided by an embodiment of the invention. Referring to FIG. 5, the shield cleaning assembly 330 includes a movable rod 331 and a cleaning plate 332. The movable rod 331 is movably inserted through the support plate, the cleaning plate 332 is fixedly connected to one end of the movable rod 331, and the rotating member 326 is always abutted against the other end of the movable rod 331. The cleaning plate 332 can be driven to periodically extend in the first direction between the monitoring device shielding mechanism 200 and the lens 111 by moving the lever portion 331.
Specifically, the shield cleaning assembly 330 further includes a roller 333 and two mounting risers 335. Two mounting plates 335 are spaced apart from and parallel to each other and are mounted to the ends of the movable rod 331. The rotating shaft of the roller 333 is clamped between the two mounting vertical plates 335, rotatably connected to the moving rod 331, and abuts against the rotating member 326.
More specifically, the object-blocking cleaning assembly 330 further includes a first elastic element 334, the first elastic element 334 is sleeved on the movable rod 331, and two ends of the first elastic element 334 are respectively fixedly connected to the supporting plate and the other end of the movable rod 331 departing from the mounting upright plate 335. In the present embodiment, the first elastic element 334 is a spring.
The specific working process of the shelter cleaning assembly 330 of the power distribution network overhead line real-time monitoring device provided by the embodiment is that the rotating member 326 rotates, and the roller 333 always abuts against the rotating member 326 and drives the moving rod part 331 to move downwards after the roller 326 collides with the rotating member to rotate. The bottom end of the movable pole 331 penetrates the support plate, and the cleaning plate 332 is attached to one end of the movable pole 331 penetrating the support plate. When the moving rod 331 moves downward, the cleaning plate 332 moves downward, and when the cleaning plate moves downward to the height of the lens 111, the cleaning plate can abut against the lens 111 to wipe off contaminants attached to the lens 111.
When the movable rod 331 moves downward, the first elastic element 334 sleeved on the movable rod 331 is squeezed to a certain extent, so that the first elastic element 334 generates a certain resilience. When the driving force of the wind force conversion is smaller than the resilience force generated by the first elastic element 334, the first elastic element 334 drives the moving rod 331 to move upward. So relapse and then make and remove pole portion 331 and can carry out reciprocating type cycle and remove from top to bottom, and can laminate mutually with camera lens 111 when removing the cleaning plate 332 that pole portion 331 bottom set up to the realization is to camera lens 111's automatic clearance, guarantees that the camera lens 111 of watch-dog 110 front end is clean and tidy all the time, improves real time monitoring effect.
Example two
Fig. 6 shows a schematic structural diagram of fig. 2 with a structural mark a, and referring to fig. 2 and fig. 6, the difference between the present embodiment and the first embodiment is that the power distribution network overhead line real-time monitoring device provided by the present embodiment includes not only the real-time monitoring apparatus 100, the monitoring device protection mechanism 200, and the monitoring device self-cleaning mechanism 300, but also two side protection structures 400. Referring to fig. 2, the two side protection structures 400 are respectively connected to two sides of the monitoring device protection mechanism 200, and can block a gap between the protection cover 210 of the monitoring device protection mechanism 200 and the lens 111. The side protection structure 400 can block the sundries carried by the wind in the windy weather, and prevent the sundries from flying and colliding on the lens 111 to generate huge impact force to damage the real-time monitoring device 100.
Specifically, the side shielding structure 400 includes a plurality of second elastic members 410 and a baffle 420, and both ends of the second elastic members 410 are respectively connected to the monitoring device shielding mechanism 200 and the baffle 420. A buffering gap 440 is formed between the flap 420 and the shield cap 210 by the spacing action of the second elastic member 410. When the sundries are collided with the baffle plate 420, the width of the buffer gap 440 is gradually reduced due to the buffer function of the second elastic element 410, and the baffle plate 420 does not strongly collide with the shield 210 and the side of the lens 111. In the present embodiment, the second elastic element 410 is a spring.
Preferably, the side protection structure 400 further includes an insertion block 430, a plurality of sliding grooves 421 are formed on the baffle 420 corresponding to the positions of the plurality of second elastic elements 410, the insertion block 430 is slidably connected in the sliding grooves 421, the second elastic elements 410 are sleeved outside the insertion block 430, and two ends of the second elastic elements are respectively fixedly connected to the bottom of the insertion block 430 and the side of the slot of the sliding groove 421. In the free state, the second elastic element 410 is not compressed, a part of the insertion block 430 extends into the sliding slot 421, and a space for the insertion block 430 to extend into is reserved in the sliding slot 421.
Specifically, when an impact collides against the baffle 420 disposed on the surface of the side protection structure 400, the baffle 420 moves toward the lens 111 to press the second elastic element 410 disposed on the shield cap 210, and the second elastic element 410 generates a contact force in the opposite direction through its deformation to weaken the impact force, thereby preventing the real-time monitoring device 100 inside the side protection structure 400 and the cleaning plate 332 of the object-cleaning assembly 330 from being damaged.
