The scraping strip 350 is a rubber scraping strip with a T-shaped cross section, the material can be referred to the scraping strip of the windshield wiper of the automobile, and meanwhile, the pre-bending with a certain curvature radius is reserved during processing, so that the situation that local stress is overlarge due to bending with a small curvature radius after installation is prevented, and the scraping effect and the service life are influenced. The installation of the wiping mechanism 300 is completed so far. Meanwhile, in order to facilitate maintenance and servicing of the present system, the wiping mechanism 300 is designed with a design that facilitates worker replacement of the aged wiper strip. As shown in fig. 14, a limit lever 380 parallel to the connection pin hole is installed on the bar fixing frame 310, and a limit groove 390 is cut at the outer edge of the pin hole where the first-stage bar fixing frame 320 is connected with the bar fixing frame 310. When the scraping strip 350 needs to be replaced, the first-stage scraping strip frame 320 is pulled in the opposite direction, and after the scraping strip frame passes through the balance point of the tension spring 370, the scraping strip frame is reversely pulled to be opened by the tension spring 370 and is fixed in the opened state by the limiting groove 390 and the limiting rod 380, so that the scraping strip is convenient for workers to replace.
As shown in fig. 15 and 16, in the embodiment of the present invention, a housing 700 is further included, which includes an upper case 710 and a lower case 720, the upper case 710 is disposed on the mounting frame 110, the lower case 720 is disposed on the rotation mechanism 200, and the top of the lower case 720 is overlapped with the inside of the bottom end of the upper case 710. The upper case 710 may have a split structure, and a rubber sealing strip is installed at a seam between the split structures to ensure water resistance; the lower housing 720 is mounted on the periphery of the rotating mechanism 200 through fasteners such as screws, and can be of an integrally formed structure or a split structure, and a rubber sealing strip is mounted at a joint between the split structures to ensure water resistance. In addition, the upper casing 710 and the lower casing 720 rotate relatively during operation, so as shown in fig. 16C, the joint is designed by pressing the upper casing 710 against the lower casing 720, so that precipitation, floating, etc. can be ensured to slide along the outer surface and not enter the system, and felt sand prevention can be additionally arranged at the joint for areas with larger wind sand in the northwest part.
As shown in fig. 17, the working process of the automatic cleaning device for a spherical camera provided by the embodiment of the invention is as follows: when the background control center detects that dirt is attached to the spherical protection cover of the camera, the background control center sends a task instruction to the automatic cleaning device of the spherical camera, the task instruction is transmitted to the control board 630 through the electric slip ring 610 and the collecting contact 620, the MCU micro-control chip on the control board 630 executes a cleaning program after receiving a starting signal, the water supply pump driving module is sent to periodically supply water for the water pump 520, meanwhile, the driving motor driving module is sent to supply power for the driving motor 410, the driving motor 410 is meshed through the driving gear 430 to drive the rotating mechanism 200 to rotate, and meanwhile, the scraping strip 350 scrapes the spherical outer cover which is wetted by spraying along with the rotation. After one revolution of the follower rotation mechanism 200, a breakpoint exists on one of the position detection channels of the electrical slip ring 610, and the position detection channel outputs an angular position signal to the control board 630 when the collective contact 620 passes through the breakpoint. The control board 630 after receiving this signal issues a command to terminate the periodic power to the water pump 520 by the water pump drive module and the spray mechanism 500 stops working. When the driving motor 410 drives the follow-up rotating mechanism 200 to rotate once again, that is, the scraping bar 350 scrapes the spherical glass cover once again, the collecting contact 620 passes the position detecting channel breakpoint again, the position detecting channel outputs an angle position signal again, and the control board 630 sends a command to terminate the power supply to the driving motor 410. The whole system then enters a standby state. In addition, a liquid level meter can be installed in the water storage tank 510, and after the signals are processed by the control board 630, the signals are sent to a terminal computer by the electric slip ring 610, so that workers can be timely reminded to supplement the water storage tank 510.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
