Description

[0002] In large-scale power construction scenarios, multi-angle monitoring and early warning devices are one of the most important safety measures. These systems are designed to improve the safety of construction sites and prevent accidents through real-time monitoring and early warning. The execution end of the monitoring and early warning device is the camera. To ensure that the camera can work safely, some large-scale power construction sites with relatively harsh environments will be equipped with protective covers on the outside of the camera. However, after long-term work, there will be some adhesions on the surface of the protective cover, which will affect the acquisition clarity of the camera. Therefore, a cleaning structure will be designed on the periphery of some protective covers to clean the outer surface of the protective cover.

[0003] Traditional cleaning methods for the outer surface of protective covers mostly use fixed brushes or water spray cleaning. These two methods have the following drawbacks:

[0004] (1) There is a blind spot in cleaning: the static bristles cannot cover the entire surface of the protective cover (cleaning rate <70%), resulting in the accumulation of rainwater, dust, and oil, and blurred imaging;

[0005] (2) Stubborn stains are difficult to remove: snow, bird droppings and other adherent substances cannot be effectively removed by a single rotating brush bar;

[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0032] Example 1:

[0033] The present invention provides a multi-angle monitoring and early warning device for large-scale power construction scenes, comprising a mounting plate 2 for mounting the device on a power tower, a conical protective cover 1 fixedly mounted on one side of the mounting plate 2, a cleaning mechanism 3 for cleaning the surface of the protective cover 1 disposed on the outside, and a camera 41 for monitoring disposed inside the protective cover 1;

[0034] See Figure 1 、 Figure 3 and Figure 4 The cleaning mechanism 3 includes a brush rod 33 equidistantly arranged on the periphery of the protective cover 1, and bristles are arranged on the surface of the brush rod 33, and the brush rod 33 is close to the outer wall of the protective cover 1. The end of each brush rod 33 away from the central axis of the mounting plate 2 is commonly provided with a running component 32 for driving it to rotate synchronously around the outer wall of the protective cover 1. The running component 32 includes a support frame 323 arranged at one end of the brush rod 33 away from the central axis of the mounting plate 2, and the inside and outside of the support frame 323 are commonly provided with a movable component 31 for controlling the movement of the brush rod 33 along its own axis direction, and the outside of each support frame 323 is also commonly provided with a linkage part 34 for synchronously controlling the operation of each movable component 31; a direction adjustment mechanism 4 for multi-directional adjustment of the shooting angle of the camera 41 is provided between the camera 41 and the mounting plate 2; by cooperating with the movable component 31 and the running component 32, the activity of the brush rod 33 can be increased and the cleaning effect can be improved.

[0035] As can be seen from the above, the protective cover 1 provides external protection for the camera 41 , reducing the impact of rain and snow on the camera 41 .

[0036] See Figure 2 The direction adjustment mechanism 4 includes a mounting base 42 fixedly connected to the base of the camera 41, and a worm gear 2 44 is fixedly connected to the mounting base 42 through a pin rod. The pin rod rotates and passes through the two side walls of the arch frame 43. Both ends of the arch frame 43 are rotatably connected to the support 48, and the support 48 is fixedly connected to the mounting plate 2. One end of the arch frame 43 is fixedly connected to a connecting plate 46 through a plurality of fixing pins 45. The connecting plate 46 is fixedly connected to the output end of the motor 3 47. The motor 3 47 is fixedly connected to the mounting plate 2. The outer periphery of the worm gear 2 44 is meshed with a worm 2 49. The two ends of the worm 2 49 are respectively rotatably connected to the support 48 and extend outward away from one end of the motor 3 47 to be fixedly connected to the output end of the motor 410. The motor 410 is fixedly connected to the mounting plate 2.

[0037] As can be seen from the above, the motor three 47 rotates to control the connecting plate 46 to drive the arch frame 43 to rotate, and the arch frame 43 rotates to control the camera 41 to rotate in the X direction. The motor four 410 rotates to control the worm two 49 to rotate and drive the worm gear two 44 to rotate. The worm gear two 44 drives the mounting base 42 to rotate through the pin rod, thereby controlling the camera 41 to rotate in the Y direction. The combined rotation in the X and Y directions is adopted to achieve all-round viewing angle coverage of the camera 41.

[0038] See Figure 1 、 Figure 3 、 Figure 4 and Figure 6The gear 327 of the outer ring 322 is fixedly mounted on the driving mechanism 324, and the gear 327 of the outer ring 322 is meshed with each other.

[0039] As can be seen from the above, the motor 328 drives the rotating ring 322 to rotate, and the rotating ring 322 controls the support frame 323 to rotate around the central axis of the protective cover 1, and the support frame 323 drives each brush rod 33 to brush and clean the surface of the protective cover 1. During the revolution of the brush rod 33, the bevel gear ring 325 rotates along the bevel gear ring 324, thereby driving the brush rod 33 to rotate through the rotating sleeve 326, which can change the adhesion area of ​​dust and other substances, and avoid the situation where the substances are too concentrated in one place, affecting the revolution of the brush rod 33. The cleaning effect is improved by the dual movement of the revolution and rotation of the brush rod 33.

[0040] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The movable assembly 31 includes a movable frame 314 rotatably mounted on one end of the brush rod 33 close to the central axis of the protective cover 1. The movable frame 314 slides through the two side walls of the support frame 323 through a keyway structure. A rack is provided on the side of the movable frame 314 away from the brush rod 33. The rack is meshed with a gear 1 315. The gear 1 315 is rotatably mounted in the support frame 323 through a pin shaft. A worm gear 1 312 is rotatably mounted on the outside of the support frame 323 through a rotating rod 311. The outer periphery of the worm gear 1 312 is meshed with a worm 1 313. The worm 1 313 is rotatably mounted on the outside of the support frame 323. The rotating rod 311 and the pin shaft are connected through a synchronous belt structure. The support frame 323 is provided with a through opening for the synchronous belt structure to pass through; the linkage part 34 includes a gear three 343 fixedly connected to one end of the worm gear 313, and each support frame 323 is fixedly connected to the outside of a mounting ring 341 coaxial with the protective cover 1, and a swivel ring 2 342 is rotatably mounted on the mounting ring 341, and a crown gear ring 3422 is provided at the position where the swivel ring 2 342 contacts the gear three 343, and an outer gear ring 2 3421 is provided on the periphery of the swivel ring 2 342, and the outer periphery of the outer gear ring 2 3421 is meshed with a gear four 344, and the gear four 344 is fixedly mounted on the output end of the motor 2 345, and the motor 2 345 is fixedly connected to the mounting ring 341.

[0041] As can be seen from the above, the motor 2 345 is used to control the rotation of gear 4 344, which drives the outer gear ring 2 3421 to rotate and control the rotation of the swivel 2 342, which drives the crown gear ring 3422 to control the rotation of gear 3 343, which drives the worm 1 313 to rotate and control the rotation of the worm wheel 1 312, and drives the gear 1 315 to rotate through the synchronous belt structure, so that the movable frame 314 is controlled to move along its own axis through the engagement of gear 1 315 and the rack. During the cleaning stage, the movable frame 314 is moved back and forth in a small range, thereby further increasing the mobility of the brush rod 33 and improving the cleaning effect. After the cleaning is completed, the movable frame 314 can be completely withdrawn outside the protection range of the protective cover 1, thereby preventing the brush rod 33 from blocking the shooting of the camera 41.

[0042] See Figure 3 A side wall of the support frame 323 close to the central axis of the protective cover 1 is provided with a through hole for the brush rod 33 to pass through, and a plurality of scraping strips 5 are fixedly connected to the inner wall of the through hole at equal intervals.

[0043] As can be seen from the above, the scraper 5 is provided to scrape and clean the brush rod 33 passing through the through-hole, so that the material adhering to the brush rod 33 is automatically detached, avoiding excessive adhesion of material and affecting the cleaning effect of the brush rod 33. In specific applications, the scraper 5 is made of flexible rubber material.

[0044] See Figure 1The protective cover 1 is a composite laminated structure, the outer layer is tempered glass, the surface of the tempered glass is coated with an antistatic nano coating, the inner layer is polycarbonate, and a UV absorber is filled between the two layers.

[0045] From the above, it can be seen that tempered glass is used to provide a high-hardness protective layer to resist the friction of the brush rod 33, and the UV absorber is used to absorb impact energy and block the degradation of internal materials by ultraviolet rays. The anti-static nano-coating can reduce the electrostatic adsorption of dust and reduce the cleaning frequency. The anti-static nano-coating is a titanium dioxide coating, and the polycarbonate material can improve the impact resistance of the protective cover 1.

[0046] Example 2: This example is basically the same as the previous example, except that Figure 4 A mounting opening is provided at the position where the movable frame 314 is connected to the supporting frame 323, and a sponge block 6 is fixedly installed in the mounting opening.

[0047] As can be seen from the above, the sponge block 6 can be used to clean the rack on the movable frame 314 to prevent matter from being mixed in the meshing gap between the rack and the gear 1 315 and affecting the meshing effect of the rack and the gear 1 315.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other.
