[0003] The patent with the publication number CN218762318U relates to the technical field of unattended bucket wheel machines in thermal power plants, including a hinged frame. A monitoring camera is hinged to the inner wall of the hinged frame. Two mounting plates are fixedly connected to the outer surface of the hinged frame. Mounting holes are formed in the upper surfaces of the two mounting plates. A heat dissipation component is installed at the right end of the monitoring camera. Two support blocks are installed on the upper surface of the monitoring camera. It can, through the cooperative setting among the hinged frame, the monitoring camera, the mounting plates, the mounting holes, the heat dissipation component, the support blocks, the dust-proof cover, and the wiping and cleaning component, use the monitoring camera to monitor the working state of the bucket wheel machine.

At different time periods, the staff can rotate and adjust the rotating shaft 4 through the motor 3 behind the bracket 5. The rotation adjustment of the rotating shaft 4 will drive the connecting block 2 to adjust the angle, and the connecting block 2 will drive the machine shell 1 to adjust the angle. At the same time, at each time period, the direct sunlight angle is different. When adjusting the angle of the machine shell 1, if sunlight hits the lens, at this time, the operator can remotely start the motor 15 to work. The motor 15 will drive the threaded rod 16 to rotate through the output end. The rotation of the threaded rod 16 will drive the C-shaped rod 17 to move through the thread groove on the circumferential surface. The C-shaped rod 17 drives the sunshade 18 to move, so that the sunshade 18 extends out from the inside of the baffle 8 to block the light on the left side of the machine shell 1, which can block direct light, reduce glare and reflection, make the details of the bright and dark parts in the image clearly presented, improve the overall quality and visibility of the image, and can also block part of the ultraviolet rays, reduce the ultraviolet damage to the lens, delay the aging speed of the lens, and maintain the clarity and light transmittance of the lens; A connecting block 2 is fixedly connected to the top of the housing 1.

[0013] Overall working principle: When the angle of the housing 1 is adjusted, if sunlight hits the lens, the C-shaped rod 17 is driven by the motor 15 to shade the lens, which can block direct light, reduce glare and reflection, and improve the overall quality and visibility of the image; when the angle of the housing 1 is adjusted, the rotation of the rotating shaft 4 will drive the clamping block 11 and the clamping plate 14 to limit the housing 1, preventing the internal mechanical structure from being damaged due to excessive twisting and pulling, being beneficial to improving the quality of the monitoring picture, and facilitating the observation and analysis of the monitoring content.

[0014] Please refer to Figures 1 - 10, on the basis of the above embodiments, in another embodiment of the present invention, the anti-blocking mechanism 6 includes a positioning block 61. A reciprocating lead screw 62 is rotatably connected to the inner wall of the positioning block 61. A gear 63 is fixedly connected to the circumferential surface of the reciprocating lead screw 62. An L-shaped rod 65 is movably connected to the circumferential surface of the reciprocating lead screw 62. A round rod 66 is rotatably connected to the inner wall of the L-shaped rod 65 through a torsion spring. A scraper 67 is fixedly connected to the circumferential surface of the round rod 66. A straight rod 68 is fixedly connected to the inner wall of the L-shaped rod 65. A rack 64 is fixedly connected to the bottom of the C-shaped rod 17; While shading the lens, the movement of the C-shaped rod 17 drives the movement of the rack 64. The movement of the rack 64 is engaged with the circumferential surface of the gear 63 through the teeth at the bottom, thereby driving the gear 63 to rotate. The gear 63 drives the reciprocating lead screw 62 to rotate. The rotation of the reciprocating lead screw 62 drives the L-shaped rod 65 to reciprocate through the reciprocating chute on the circumferential surface. The L-shaped rod 65 drives the round rod 66 to move. The round rod 66 drives the scraper 67 to move to clean the front lens of the housing 1. Among them, the straight rod 68 will limit the scraper 67 to prevent the scraper 67 from shifting when cleaning clockwise. These impurities can be removed, enabling the light to accurately focus on the imaging element, thereby obtaining clear and sharp images, improving the overall shooting efficiency, and at the same time reducing the corrosion of the lens by the impurities, further improving the service life of the device; A long plate 69 is fixedly connected to the circumferential surface of the round rod 66. A rotating plate 610 is rotatably connected to the inner wall of the long plate 69 through a torsion spring. An extrusion plate 611 is fixedly connected to the left side of the housing 1. The top of the housing 1 is fixedly connected to the bottom of the positioning block 61. The circumferential surface of the reciprocating lead screw 62 is rotatably connected to the inner wall of the cover 8. The bottom of the rack 64 is engaged with the circumferential surface of the gear 63. The rack 64 contacts the inner wall of the cover 8. The L-shaped rod 65 contacts the circumferential surface of the housing 1. The scraper 67 contacts the left side of the housing 1. The scraper 67 contacts the inner wall of the L-shaped rod 65. The front side of the straight rod 68 contacts the rear side of the scraper 67. The front inclined surface of the rotating plate 610 contacts the rear inclined surface of the extrusion plate 611; While cleaning the lens, if the cleaning is carried out clockwise, the circular rod 66 moves to drive the long plate 69 to move. The movement of the long plate 69 drives the rotary plate 610 to move. The movement of the rotary plate 610 contacts the pressing plate 611 through the inclined plane, resulting in the rotation of the rotary plate 610. However, due to the limitation of the straight rod 68 on the circular rod 66, the circular rod 66 will not drive the scraper 67 to rotate when it rotates clockwise. When resetting counterclockwise, the limiting circular rod 66 has no limitation, so that the rotary plate 610 contacts the pressing plate 611, driving the rotary plate 610 to rotate. The rotary plate 610 drives the long plate 69 to rotate, the long plate 69 drives the circular rod 66 to rotate, and the circular rod 66 drives the scraper 67 to rotate, stopping the cleaning of the lens counterclockwise. Not cleaning in the reverse direction is to avoid possible damage to the structure of the lens caused by reverse operation, improve the service life of the lens, and also prevent some adhesive substances from blocking the use during repeated cleaning, further improving the shooting clarity of the lens during monitoring and the overall working efficiency of the device.

[0015] Overall working principle: While shading the lens, the C-shaped rod 17 drives the scraper 67 to move to clean the front lens of the machine shell 1, which can remove these impurities and improve the overall shooting efficiency. While cleaning the lens, if the cleaning is carried out clockwise, the circular rod 66 will not drive the scraper 67 to rotate. When resetting counterclockwise, the limiting circular rod 66 drives the scraper 67 to rotate, stopping the cleaning of the lens counterclockwise. Not cleaning in the reverse direction is to avoid possible damage to the structure of the lens caused by reverse operation, improve the service life of the lens, and also improve the overall working efficiency of the device.

When the machine shell 1 is working, to adjust the angle of the machine shell 1, it will be hinged with the top of the support 5 through the telescopic hinge rod 71, driving the telescopic hinge rod 71 to move down and contract. At the same time, because the top of the telescopic hinge rod 71 is hinged with the top of the U-shaped rod 72, the U-shaped rod 72 is driven to move. The U-shaped rod 72 drives the connecting rod 74 to move. The connecting rod 74 drives the pulley 75 to move. A rubber ring is sleeved on the circumferential surface of the pulley 75 to increase the friction. The movement of the pulley 75 contacts the right side of the machine shell 1 through the circumferential surface, driving the pulley 75 to rotate. The pulley 75 drives the connecting rod 74 to rotate. The connecting rod 74 drives the brush barrel 76 to rotate to clean the heat dissipation port 13, preventing the accumulation of dust and other sundries, enabling the air to smoothly conduct heat exchange through the heat dissipation holes, quickly dissipating the heat generated inside the camera, avoiding the device temperature from being too high due to heat accumulation, and further improving the monitoring efficiency of the device.

The left side of the trapezoidal rod 73 contacts the right side of the casing 1; During the cleaning, the movement of the U-shaped rod 72 drives the movement of the trapezoidal rod 73. The trapezoidal rod 73 moves and contacts the percussion plate 77 through the inclined surface at the top, thereby driving the percussion plate 77 to rotate. The percussion plate 77 is connected to the inner wall of the limiting plate 78 through a torsion spring. When the trapezoidal rod 73 leaves, the percussion plate 77 will be reset through the torsion spring to strike the heat dissipation port 13, which can loosen the dust attached to the heat dissipation holes and inside, making the dust easier to be removed by subsequent cleaning operations, helping to maintain the smoothness of the heat dissipation holes and improving the heat dissipation efficiency.

[0017] Overall working principle: When the casing 1 is working, the telescopic hinge rod 71 drives the brush barrel 76 to rotate to clean the heat dissipation port 13, preventing the accumulation of dust and other sundries, enabling air to smoothly pass through the heat dissipation holes for heat exchange, and further improving the monitoring efficiency of the device; during the cleaning, the U-shaped rod 72 drives the percussion plate 77 to strike the heat dissipation port 13, which can loosen the dust attached to the heat dissipation holes and inside, making the dust easier to be removed by subsequent cleaning operations, helping to maintain the smoothness of the heat dissipation holes and improving the heat dissipation efficiency.
