Description

Technical Field

[0001] This invention belongs to the field of mechanical design, specifically relating to a dual-drive photoelectric device protection mechanism. Background Technology

[0002] High-precision optoelectronic equipment is often used in harsh operating conditions, so the design of protective mechanisms for optoelectronic equipment is essential.

[0003] There are three main solutions in existing technologies. First, a fixed protective cover is directly installed on the outside of the optoelectronic equipment, which is cumbersome to remove during use and requires manual intervention. Second, an independent, liftable protective cover is installed on the outside of the optoelectronic product, which is lowered during use. While this allows for automatic control, it is a separate mechanism requiring ample installation space and is costly. Third, the protective cover is directly fixed to the product's azimuth rotation axis, with the cover and the azimuth rotation mechanism sharing a single motor. This directly increases the rotational inertia of the azimuth motor, hindering steady-state azimuth control. Furthermore, the bulky casing makes maintenance difficult, disassembly is inconvenient, and this protection method cannot protect the pitch rotation platform. Summary of the Invention

[0004] The technical problem to be solved:

[0005] To overcome the shortcomings of existing technologies, this invention provides a dual-drive photoelectric device protection mechanism. By setting a pitch protection cover in the circumferential direction of the photoelectric device's pitch rotation and an azimuth protection cover in the circumferential direction of its azimuth rotation, the mechanism protects the photoelectric device when it is not in operation. Simultaneously, rotating the azimuth protection cover facilitates maintenance of the pitch axis system. This invention is suitable for protecting photoelectric devices used in harsh environments and has the advantages of compact structure, cost-effectiveness, and ease of transportation and installation.

[0007] The rotation axis of the azimuth protection cover 2 is coupled to the azimuth rotation axis of the photoelectric device. By controlling the rotation of the rotation axis of the azimuth protection cover 2, the position of the azimuth protection cover 2 in the azimuth circumferential direction can be adjusted. Through synchronous control, the azimuth protection cover 2 rotates with the photoelectric device at the same azimuth angle when the photoelectric device is in use.

[0008] The rotation axis of the pitch protection cover 1 is coupled to the pitch rotation axis of the optoelectronic device. By controlling the rotation of the rotation axis of the pitch protection cover 1, the position of the pitch protection cover 1 in the pitch circumferential direction can be adjusted. Through synchronous control, the pitch protection cover 1 rotates with the optoelectronic device at the same pitch angle when the optoelectronic device is in use.

[0014] A further technical solution of the present invention is: the azimuth protection cover 2 is rotatably connected to the protection motor fixing part 8 through its rotation axis system, and the azimuth protection cover base plate 5, the azimuth protection cover meshing large gear 6, and the azimuth protection cover bearing 7 are arranged sequentially along the axial direction of the rotation axis system of the azimuth protection cover 2.

[0015] The azimuth protection cover 2 is an annular surface with an opening, and its bottom is coaxially mounted on the azimuth protection cover base plate 5; the azimuth protection cover base plate 5 is a circular plate with a central through hole, wherein the bottom of the through hole is coaxially fixed with the azimuth protection cover meshing gear 6, and the azimuth protection cover meshing gear 6 is rotatably connected to the protection motor fixing part 8 through the azimuth protection cover bearing 7.
