The wind power conversion bin 311 is provided with a ventilation opening, and the middle part of the wind power conversion bin 311 is vertically provided with a support plate 314 parallel to the bin bottom plate of the wind power conversion bin 311. The fan 312 includes a fan blade and a rotating shaft, the rotating shaft is rotatably disposed through the support plate 314, and one end extending out of the support plate 314 is in transmission connection with the driving force transmission assembly 320.

Fig. 4 shows an installation schematic diagram of a shelter cleaning assembly of a real-time monitoring device for an overhead line of a power distribution network according to an embodiment of the present invention. Referring to fig. 3 to 4, the driving force transmission assembly 320 includes a housing 321, a first transmission lever 322, a first rotating wheel 323, a second rotating wheel 324, a second transmission lever 325, and a rotating member 326.
Specifically, the first transmission rod 322 is rotatably connected to the wind power conversion bin 311 and is in transmission connection with a rotating shaft of the fan 312, the first rotating wheel 323 is fixedly connected to the first transmission rod 322, the second rotating wheel 324 is rotatably arranged in the casing 321 through a supporting shaft and is in meshed connection with the first rotating wheel 323, the second transmission rod 325 is rotatably arranged in the casing 321 and is in transmission connection with the supporting shaft, the rotating member 326 is fixedly connected to the second transmission rod 325, and when the fan 312 rotates, the rotating member 326 is driven to rotate by transmission of the first transmission rod 322, the first rotating wheel 323, the second rotating wheel 324 and the second transmission rod 325 in sequence, and in this embodiment, the transmission connection is realized by gear engagement.
Specifically, the rotating member 326 is eccentrically disposed with respect to the second transmission rod 325. The driving force drives the rotating member 326 to rotate through the transmission of the first transmission rod 322, the first rotating wheel 323, the second rotating wheel 324 and the second transmission rod 325. Since the rotating member 326 is always abutting the shutter cleaning assembly 330, the shutter cleaning assembly 330 can be driven to periodically move up and down as the eccentric rotating member 326 rotates.
More specifically, the diameter of the first rotating wheel 323 is larger than that of the second rotating wheel 324, when the first rotating wheel 323 is driven by wind power to rotate by a smaller angle, the second rotating wheel 324 meshed with the first rotating wheel 323 can rotate by a larger angle, and the rotating piece 326 can rotate to drive the shielding object cleaning assembly 330 to perform more times of periodical 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, and the limiting block 327 is fixedly connected to the top of the inner side of the casing 321, in which a rotating groove 328 is formed, 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 real-time monitoring device for an overhead line of a power distribution network according to an embodiment of the present invention. Referring to fig. 5, the shutter cleaning assembly 330 includes a moving rod 331 and a cleaning plate 332. The movable rod 331 is movably disposed through the support plate, and 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 between the monitoring device guard mechanism 200 and the lens 111 in the first direction by moving the lever portion 331.
Specifically, the shade cleaning assembly 330 further includes a roller 333 and two mounting risers 335. The two mounting plates 335 are disposed in parallel with each other at a distance from each other and mounted to the end of the moving rod 331. The rotating shaft of the roller 333 is clamped between the two mounting plates 335, rotatably connected to the moving rod 331, and abuts against the rotating member 326.
More specifically, the shelter cleaning assembly 330 further includes a first elastic element 334, where the first elastic element 334 is sleeved on the moving rod 331, and two ends of the first elastic element are respectively and fixedly connected to the support plate and the other end of the moving rod 331, which is away from the mounting riser 335. In this embodiment, the first elastic element 334 is a spring.
The specific working process of the shelter cleaning assembly 330 of the overhead line real-time monitoring device for the power distribution network provided by the embodiment is that the rotating member 326 rotates, and the roller 333 which is always abutted against the rotating member 326 is driven to move downwards after the roller 333 is abutted against the rotating member 326 to rotate. The bottom end of the moving rod 331 passes through the support plate, and the cleaning plate 332 is fixedly connected to one end of the moving rod 331 passing through the support plate. When the moving rod 331 moves downward, the cleaning plate 332 moves downward, and when it moves downward to the height of the lens 111, it can be attached to the lens 111, so as to erase the contaminants attached to the lens 111.
When the moving rod 331 moves downward, a certain compression is generated on the first elastic element 334 sleeved on the moving rod 331, so that the first elastic element 334 generates a certain resilience force. When the driving force of wind power 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 upwards. So repeatedly and then make and remove pole portion 331 and can reciprocate the 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 realize the automatic clearance to camera lens 111, guarantee that camera lens 111 of monitor 110 front end is clean and tidy all the time, improve real-time monitoring effect.
Example two
Fig. 6 shows a schematic structural diagram of a structure labeled a in fig. 2, and referring to fig. 2 and 6, this embodiment is different from the first embodiment in that the real-time monitoring device for an overhead line of a power distribution network provided in this embodiment includes not only the real-time monitoring device 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, two side protection structures 400 are respectively connected to two sides of the monitoring device protection mechanism 200, and can shield a gap between the protection cover 210 and the lens 111 of the monitoring device protection mechanism 200. The side protection structure 400 can block sundries carried by wind in windy weather, and prevent the sundries from flying and striking the lens 111 to generate huge impact force so as to damage the real-time monitoring device 100.
Specifically, the side guard structure 400 includes a plurality of second elastic members 410 and a barrier 420, and both ends of the second elastic members 410 are respectively connected to the monitoring device guard mechanism 200 and the barrier 420. A buffer gap 440 is formed between the barrier 420 and the shield 210 by the spacing action of the second elastic member 410. When the foreign matters fly against the barrier 420, the width of the buffer gap 440 is gradually reduced due to the buffer effect of the second elastic member 410, and the barrier 420 does not impact the protection cover 210 and the side of the lens 111. In this 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 second elastic elements 410, the insertion block 430 is slidably connected to 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 and fixedly connected to the bottom of the insertion block 430 and the sides of the grooves 421. When in the free state, the second elastic element 410 is not compressed, a part of the plug 430 extends into the sliding groove 421, and a space for the plug 430 to extend into is left in the sliding groove 421.
Specifically, when the striker collides with the baffle 420 disposed on the surface of the side protection structure 400, the baffle 420 moves in a direction close to the lens 111, the second elastic element 410 disposed on the protection cover 210 is pressed, the second elastic element 410 generates an opposite collision force through its deformation, and the collision force is weakened, so that the real-time monitoring device 100 inside the side protection structure 400 and the cleaning plate 332 of the shutter cleaning assembly 330 are prevented from being damaged. The side protection structure 400 makes the operation of the self-cleaning mechanism 300 of the monitoring device safer, and can reduce dust falling onto the lens 111 at the front end of the monitor 110, and maintain the normal monitoring function of the real-time monitoring device 100.
