Folding structure for ship signal lamp pole

Abstract

The invention relates to a folding structure for a ship signal lamp pole. The folding structure comprises a mast and a transverse rod fixedly connected to the mast. The transverse rod is composed of fixed arms and folded arms, wherein the fixed arms are symmetrically installed on the two sides of the mast, and the folded arms are symmetrically installed on the two sides of the mast. Fixing bottom boards are fixedly connected to the upper ends and the bottoms of the ends of the fixed arms and extend out of the ends of the fixed arms. One end of each folded arm is located between the two corresponding fixing bottom boards, the other end of each folded arm is provided with a signal lamp, each folded arm and the two corresponding fixing bottom boards are connected through a fulcrum bolt and a fastening bolt, the ends, extending out of the corresponding fixing bottom boards, of each fulcrum bolt and each fastening bolt are provided with nuts, and when each fastening bolt is detached, the corresponding folded arm can rotate in the horizontal plane with the nut of the corresponding fulcrum bolt as the circle center. By the adoption of the folding structure, through the rotatable folding design of the folded arms, the distance between a seaman and each lamp is greatly shortened, the operation process is simple, safety is improved, and a reliable technical guarantee is provided for services and maintenance in ship operation. Meanwhile, the weight of a hull can be better controlled.

Description

technical field [0001] The invention relates to the structure of a marine signal light pole, in particular to a folding structure of a marine signal light pole which is convenient for maintenance. Background technique [0002] According to "International Regulations for Preventing Collisions at Sea 1972" / Appendix 1 / Requirements for position and technical details of lights and shapes / 9. Horizontal light arc: (2) ①The all-round light should be placed in a place not surrounded by the mast, topmast or Where buildings shade the light arc at an angle greater than 6 degrees, except for the anchor lights specified in Article 30, the anchor lights need not be placed at unrealistic heights above the hull. In the actual ship design, in order to meet the requirements of the shielding angle, the installation position of the lamp is generally far away from the mast. [0003] Such as Figure 4 As shown, the lamps in the prior art are designed to be 1.5m away from the mast, and this design...

AI Technical Summary

Problems solved by technology

The disadvantage of this design is that since the lamps are installed far away from the mast, a special maintenance operation platform 8 needs to be set up, and the operation is very dangerous. It is very difficult for the crew to maintain during operation, and sometimes even endangers the lives of the crew.
