Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing.
[0027] like Figure 1-5 As shown, this embodiment provides a detachable scraping mechanism for a diversion-shaped antenna mast, including a slidable scraping ring 1 sleeved on the outer periphery of the antenna 5, and a scraping ring 1 is arranged on the scraping ring. element 2. The scraping element 2 is a scraping ring, and a ring groove for accommodating the scraping ring is provided in the scraping ring 1 . A locking mechanism 3 is provided on the outer periphery of the scraping ring 1, the lower end of the locking mechanism 3 is fixed to the guide support frame 8, and a guide with a variable cross section is installed between the guide support frame 8 and the antenna 5. Shaped mast 6, wherein, antenna 5 is installed on the diversion-shaped mast 6, constitutes the whole body of diversion-shaped antenna mast, and this whole body axially slides up and down in the guide ...

The invention discloses a detachable scraping mechanism for a deflector antenna mast, which comprises a scraping ring slidably sleeved on the outer periphery of the antenna, and is characterized in that a locking mechanism is arranged on the outer periphery of the scraping ring , the lower end of the locking mechanism is fixed to the guide support frame, a diversion-shaped mast is installed between the guide support frame and the antenna, the scraper ring is arranged above the diversion-shaped mast, and An unlocking mechanism is provided on the top for unlocking the locking mechanism so that the locking mechanism is separated from the scraping ring, and an anti-rotation mechanism is also provided on the scraping ring, and the anti-rotation mechanism is configured with the diversion-shaped mast. The present invention uses mast lifting power to work without additional power source and separate drive mechanism, which not only saves energy, but also saves the space occupied by separate drive mechanism, making the structure compact and highly integrated.
Description
technical field [0001] The invention belongs to the field of ship devices, and in particular relates to a detachable dirt scraping mechanism for a diversion-shaped antenna mast. Background technique [0002] Underwater vehicles such as manned submersibles and UUVs are generally equipped with a liftable communication antenna. When the underwater vehicle needs to communicate with the outside world, the antenna sticks out of the water and lowers after the work is completed. The underwater communication antenna works in the ocean environment for a long time, and the surface is easy to adhere to the sludge and even grow marine organisms, which affects the insulation characteristics of the antenna, and then affects the performance of the antenna. The antenna is generally installed in a circular mast to form a cylindrical antenna mast. A scraper ring is set on the top of the mast to scrape the antenna when the antenna is raised and lowered to remove surface dirt, prevent the growth...
