[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0031] The present application discloses a visual camera dust cover based on controllable timing pulse pneumatic dust removal.
[0032] Embodiment 1:
[0033] Reference Figure 1 A visual camera dust cover based on controllable timing pulse pneumatic dust removal includes a visual camera protective cover component 1, a pneumatic axial flow dust removal component 2 and an automatic timing control component 3, wherein the visual camera protective cover component 1 includes a protective cover cylinder 11, a protective cover window cover 12, a protective cover bottom cover 14 and a gland 15. When the visual camera is installed, it is located inside the protective cover cylinder 11. The protective cover bottom cover 14 is fixedly connected to the bottom of the protective cover by screws. A threaded hole is opened in the middle of the protective cover bottom cover 14. The gland 15 is arranged at the bottom of the protective cover bottom cover 14 and is threadedly connected to the threaded hole. The protective cover cylinder 11, the protective cover bottom cover 14 and the gland 15 are located on the same axis. The circuit of the visual camera is connected to the external power supply through the cable gland 15, and the cable gland 15 protects the circuit. The protective cover window cover 12 is detachably connected to the top of the protective cover cylinder 11. The protective cover window cover 12 and the protective cover cylinder 11 are located on the same axis. The camera head of the visual camera is protected by the protective cover window cover 12 to ensure normal shooting of the visual camera; the pneumatic axial flow dust removal component 2 is located above the protective cover window cover 12 and faces the protective cover window cover 12. The airflow generated by the pneumatic axial flow dust removal component 2 is used to clean the protective cover window cover 12; the automatic timing control component 3 is used to control the opening and closing of the pneumatic axial flow dust removal component 2.
[0034] In this embodiment, the protective cover window cover 12 is fixedly connected to the top of the protective cover cylinder 11 by screws. In order to improve the shooting effect of the visual camera, a mounting groove 121 is opened in the middle of the protective cover window cover 12. An optical glass 13 is fixedly connected in the mounting groove 121. The upper surface of the optical glass 13 is flush with the upper surface of the protective cover window cover 12, thereby improving the integrity of the protective cover window cover 12 and the optical glass 13.
[0035] In order to clean the protective cover window cover 12, the pneumatic axial flow dust removal assembly 2 includes an axial flow fan 21, a guide port 22 and a rectifying port 23. The axial flow fan 21 is arranged on the protective cover cylinder 11. Specifically, the axial flow fan 21 is connected to the protective cover cylinder 11 by a bolt 24. The bolt 24 is parallel to the protective cover window cover 12. The axial flow fan 21 can rotate with the bolt 24 as the rotation axis. A limited block is fixedly connected to the axial flow fan 21. An arc-shaped limit groove is provided on the protective cover cylinder 11. The limit block is located in the limit groove. By rotating the axial flow fan 21 can adjust the angle of the axial flow fan 21 so that the air outlet of the axial flow fan 21 faces the protective cover window cover 12, so as to blow away the dust on the protective cover window cover 12. The guide port 22 is fixedly connected to the air inlet of the axial flow fan 21 by screws, and the rectifying port 23 is fixedly connected to the air outlet of the axial flow fan 21 by screws and faces the protective cover window cover 12. The rectifying port 23 is flat at one end away from the axial flow fan 21. The airflow is more concentrated after passing through the rectifying port 23, so that the airflow can better blow away the dust on the surface of the protective cover window cover 12.
[0036] To facilitate the control of the opening and closing of the axial flow fan 21, the automatic timing control component 3 includes an AC-to-DC module 31, a digital timing cycle controller 32 and a relay 33, and also includes an air switch. The voltage input ends of the digital timing cycle controller 32 and the relay 33 are connected to the 220V AC power supply in parallel through wires, and the air switch is connected to the parallel main line. The timing control output end of the digital timing cycle controller 32 is electrically connected to the input control end of the relay 33, the voltage output end of the relay 33 is electrically connected to the voltage input end of the AC-to-DC module 31, and the DC output end of the AC-to-DC module 31 is electrically connected to the DC input end of the axial flow fan 21.
[0037] During the working process, the control timing of the pulse pneumatic dust removal can be arbitrarily set through the control panel on the digital timing cycle controller 32, so that the pneumatic axial flow dust removal component 2 on the visual camera protection cover component 1 performs cyclic pulse pneumatic dust removal operations according to the set timing rules; when the entire device is in the working timing, the input voltage end and the output voltage end of the relay 33 are controlled to be connected through the digital timing cycle controller 32. At this time, the 220V voltage provided by the city power passes through the air switch and is then transmitted to the voltage input end of the AC to DC module 31 through the relay 33. The 220V AC voltage is converted into a 12V DC voltage through the AC to DC module 31. The voltage output end of the AC to DC module 31 transmits the 12V DC voltage to the voltage input end of the axial flow fan 21 through a wire, so that the axial flow fan 21 starts to rotate at high speed. The high-speed rotating micro axial flow fan 21 sucks a large amount of air from the air inlet duct 22. The sucked air enters from one end of the axial flow fan 21 and is discharged at a high speed from the other end of the axial flow fan 21. The discharged high-speed air is rectified by the rectifier port 23 and blown evenly and quickly to the surface of the optical glass 13 of the camera protective cover assembly, thereby blowing away the dust and other debris on the surface of the optical glass 13, thereby realizing automatic dust removal of the optical glass 13 window of the visual camera protective cover assembly 1; when the entire device is in a non-working sequence, the digital timing cycle controller 32 disconnects the input voltage terminal and the output voltage terminal of the relay 33, thereby putting the entire device in a stopped waiting state; according to the set timing control law, the entire device continuously performs work / stop alternating cycles according to the timing, thereby realizing pulse pneumatic dust removal of the glass lens in the visual camera protective cover assembly 1.

When the protective cover window cover 12 is installed, the clamping block 122 is embedded in the L-shaped clamping groove 111, and then the protective cover window cover 12 is rotated to make the clamping block 122 and the L-shaped clamping groove 111 snap-fit and fixed.
