Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a foldable radar mast for ships. Background Art

[0002] The radar mast is a crucial feature of a ship. It serves as a communication and lighting system for navigation and is also the highest point on the vessel. The International Maritime Organization (IMO) has clear requirements for the height of a radar mast. With the development of the global economy, bridges have been built across many bays and major rivers, restricting the navigation height of ships. This prevents ships from reaching their destination ports in a straight line, forcing them to transfer cargo between large and small vessels en route. This is time-consuming and labor-intensive, increasing transportation costs.

[0003] Patent application number 201220124977.0 discloses a retractable marine radar mast, comprising a mast base and a mast. The mast base is unique in that a fixed plate is provided, the upper end of the fixed plate being hingedly connected to the mast and the lower end of the fixed plate being fixedly connected to the mast. A telescopic rod is also provided, the fixed rod of the telescopic rod being fixedly mounted on the mast base, and the telescopic member of the telescopic rod being hingedly connected to the mast. The retractable marine radar mast designed in this utility model can adjust the mast to a certain angle by controlling the extension length of the telescopic member of the telescopic rod, thereby meeting the requirements for ships navigating in height-restricted waterways. The mast features a simple structure, is easy to use, and is cost-effective.

[0004] However, in actual operation, ships may encounter different bridge navigation height limits. When encountering a bridge with a higher height, if the entire mast is lowered, the economic benefits and navigation efficiency will be lower.

[0005] Therefore, the retractable mast should be adaptively lowered to a certain height according to the various navigation heights of bridges to improve the economy and navigation efficiency of ships. Utility Model Content

[0006] In response to the problems in the related art, the present application discloses a retractable ship radar mast, which solves the problem of low economic benefits and navigation efficiency caused by the need to retract the entire mast in the related art.

[0007] To achieve the above objectives, this application provides the following technical solutions:

[0008] A retractable radar mast for ships comprises a support base and a mast, the mast comprising an upper rod and a lower rod that can be reversibly connected, the upper rod and the top of the lower rod being hinged by a first hinge device, the bottom of the upper rod and the lower rod being fixably and detachably connected by a first fixing device, a first telescopic device being provided between the upper rod and the lower rod, the telescopic end of the first telescopic device being hinged to the upper rod, the fixed end of the first telescopic device being hinged to the lower rod, the lower rod being hinged to the top of the support base by a second hinge device, the bottom of the lower rod being fixably and detachably connected to the support base by a second fixing device, a second telescopic device being provided between the bottom of the lower rod and the support base, the telescopic end of the second telescopic device being hinged to the lower rod, and the fixed end of the second telescopic device being hinged to the support base.

[0009] As a further solution of the present application: the upper rod and the lower rod have opposite tilting directions.

[0010] As a further solution of the present application: the first fixing device and the second fixing device include a flange and a bolt assembly.

[0011] As a further solution of the present application: the first hinge device and the second hinge device include a pin assembly.

[0015] The lower rod is hinged to the top of the support seat by a second hinge device, and the bottom of the lower rod is fixedly and detachably connected to the support seat by a second fixing device. A second telescopic device is provided between the bottom of the lower rod and the support seat, and the second fixing device realizes the fixation of the lower rod and the support seat.
