Telescopic and folding sidelight device

Abstract

The invention provides a telescopic and folding sidelight device which comprises a sidelight box and a telescopic mechanism. A sidelight is fixed into the sidelight box. The telescopic mechanism comprises a stand column, a rotary rack and a telescopic rack. The stand column is in rotary connection with the rotary rack which rotates with the stand column as the axis. The telescopic rack is inserted into the rotary rack and can slide telescopically relative to the rotary rack. The sliding direction of the telescopic rack is perpendicular to the axial direction of the stand column and is the direction of a connecting line between the first end of the rotary rack and the farthest end, relative to the stand column, of the telescopic rack. The telescopic rack is in rotary connection with the sidelight box. The rotary direction, relative to the telescopic rack, of the sidelight box is parallel to the axial direction of the stand column. The stand column is fixedly mounted on the outer side of an edge guardrail of a forecastle deck, and when the telescopic and folding sidelight device is folded, the rotary rack is closely attached to the guardrail; and the sidelight device is closely attached to the guardrail after being retracted and folded, has no influence on ship operation, and does not occupy the space of a forecastle, and space using of the forecastle deck is ensured on a ship with limited space.

Description

technical field [0001] The invention relates to marine equipment, in particular to a retractable and foldable side light device. Background technique [0002] The "side light" used by ships refers to the green light on the starboard side and the red light on the port side, each displaying uninterrupted lights in a horizontal arc of 112.5 degrees, and the device is to make the lights from the front of the ship to 22.5 degrees behind the beam on each side. are displayed separately. For ships less than 20 meters in length, the sidelights may be combined into one and installed on the fore and aft centerline of the ship. In the international rules for avoiding collisions, there are strict requirements for the arrangement of the sidelights: the height of the sidelights of motor ships above the hull should not exceed three-quarters of the height of the foremast lights. These sidelights should not be so low as to be disturbed by deck lights. [0003] As a kind of ship navigation ...

AI Technical Summary

Problems solved by technology

[0005] The problem existing in the existing retractable side light device is that since the guide rail of the side light extends horizontally from the edge of the forecastle deck, in order to ensure that the side light can stretch out to a certain distance, the track needs to be of sufficient length, and when the side light is in a folded state , the track below it must occupy the space of the corresponding length on the first floor deck to meet the placement of the track, so it takes up a lot of space on the deck under the realization of the expansion and contraction of the sidelights
