As shown in fig. 14, a stopper 380 is mounted on the bar holder 310 in parallel with the connecting pin hole, and a stopper groove 390 is cut at the outer edge of the pin hole where the primary bar holder 320 and the bar holder 310 are connected. When the scraping bar 350 needs to be replaced, the primary scraping bar rack 320 is pulled in the opposite direction, and after the balance point of the tension spring 370 is crossed, the tension spring 370 pulls and opens in the opposite direction, and the limiting groove 390 and the limiting rod 380 are fixed in the opening state, so that workers can replace the scraping bar conveniently.
As shown in fig. 15 and 16, in the embodiment of the present invention, a housing 700 is further included, the housing includes an upper housing 710 and a lower housing 720, the upper housing 710 is disposed on the mounting frame 110, the lower housing 720 is disposed on the rotating mechanism 200, and the top of the lower housing 720 is lapped on the inner side of the bottom end of the upper housing 710. The upper shell 710 can be a split structure, and a rubber sealing strip is arranged at the joint between the split structures to ensure water resistance; the lower housing 720 is mounted on the periphery of the rotating mechanism 200 by fasteners such as screws, and may be an integrally formed structure or a split structure, and a rubber sealing strip is mounted at a seam between the split structures to ensure water resistance. Moreover, the upper shell 710 and the lower shell 720 rotate relatively during operation, so that as shown in a position C in fig. 16, the design that the upper shell 710 presses the lower shell 720 is adopted in a joint, so that the falling water, the sinking water and the like can be ensured to slide along the outer surface and cannot enter the system, and felt sand prevention can be additionally arranged at the joint for areas with large wind sand in the northwest.
As shown in fig. 17, the automatic cleaning device for a spherical camera according to the embodiment of the present invention includes: when a background control center detects that dirt is attached to the spherical protective cover of the camera, a task instruction is sent to the automatic spherical camera cleaning device, the task instruction is transmitted into a control board 630 through an electrical slip ring 610 and a set contact 620, a MCU micro control chip on the control board 630 receives a starting signal and then executes a cleaning program, the MCU micro control chip sends a command to a water pump driving module to periodically supply power to the water pump 520 and spray water, and simultaneously sends a command to a driving motor driving module to supply power to the driving motor 410, the driving motor 410 is meshed with 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 sprayed and wetted along with the rotation. After the servo rotating mechanism 200 runs for one circle, a breakpoint exists on a certain position detection channel of the electrical slip ring 610, and the position detection channel outputs an angle position signal to the control board 630 when the set contact 620 passes through the breakpoint. The control board 630, having received the signal, sends a command to terminate the periodic power supply of the water pump driving module to the water pump 520, and the spraying mechanism 500 stops working. When the driving motor 410 drives the following rotation mechanism 200 to rotate for one circle again, that is, the scraping bar 350 scrapes one circle of spherical glass cover again, the set contact 620 passes through the breakpoint of the position detection channel again, the position detection 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 at this moment. The entire system then enters a standby state. In addition, a liquid level meter can be installed in the water storage tank 510, signals are processed by the control panel 630 and then transmitted to a terminal computer through the electric slip ring 610, and staff are reminded to replenish the water storage tank 510 timely.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present 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 solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
