Background
In order to ensure the safety of ship navigation, the ship should be provided with fore-aft flagpole mounting signal lamps at the foremost end and the rear end. The common flagpoles are arranged at the open air parts at the two ends of the ship, and according to the arrangement and the working tasks of the ship navigation standard light models, equipment such as an anchor lamp, an operation indicating lamp, a steel wire rope eye ring for hanging color flag festoon lamps and the like needs to be arranged on the flagpoles. The reversible flagpole is arranged at the bow or the stern, and particularly, the linear limited space in the bow and stern areas of the ship is narrow, so that the accommodation of operators is limited. The flagpole is selected to have a larger height along with the increase of the tonnage of the ship, and the weight of the flagpole is increased. The flagpole is also generally required to be hung with a steel wire rope of the color-flag festoon lamp, and the flagpole becomes a stressed member and needs to have enough rigidity. When the flagpole falls down and is fixed during heavy-wave navigation, the flagpole is impacted by the waves on the deck and shakes the hull, and the flagpole needs to have enough fatigue resistance. And lamp cables should be laid in the flagpole according to relevant specifications to improve the service life.
In the marine flagpole equipment with the publication number of CN203581316U, in the use process of the marine flagpole equipment, the support which is not fallen down still has a high-size protruding deck or bulwark, the rising and the landing of the helicopter are influenced, the operation range of throwing the helicopter to the outboard is limited, the number of operators required for manually controlling the three-degree-of-freedom motion of the fallen flagpole and the erection of the flagpole is large, and the defects of how to fix the flagpole after falling down and the like are not given.
The flagpole for the ship, disclosed in the publication No. CN207292312U, has strong crack sensitivity of glass fiber reinforced epoxy resin composite material in the actual use process, obvious stress concentration on machining cracks of a car, a clamp, a drill and the like, obvious crack diffusion in the use process, small elastic modulus, large deformation deflection under stress and easy fatigue damage, the conical embedded part connecting the upper main rod and the lower main rod is made of epoxy resin adhesive, the epoxy resin adhesive is easy to fatigue damage due to brittleness and hardness, the steel wire rope hanging eye plate is arranged on the main rod eye plate, the deformation of the upper part of the flagpole is large after the steel wire rope of the color lamp is hung, even the main rod or the flagpole support rod is broken when large wind waves are continuously generated, the metal hoop can not be welded with the glass steel main rod, the metal hoop is arranged on the glass steel main rod by bolts, the glass steel main rod is subjected to large pressure, the flagpole has discontinuous internal stress and more concentrated stress points, and has insufficient fatigue strength, the three-degree-of-freedom motion of the flagpole which is turned down and erected manually needs a lot of operators who do not give how to fix the flagpole after the flagpole is turned down, the motion range is not limited, the flagpole tends to be turned over outboard under the action of wind waves in the part operation process, and the operators can lose control over the flagpole.
Publication No. CN111498008A a marine flagpole rolls over device, mechanical structure is more complicated, uses rack and pinion wearing and tearing and corrosion easy jamming for a long time, and the flagpole erects, a certain angle slope or state of falling down, and the flagpole is rocked for a long time irregular motion by the hull, drives rack and pinion and moves at little motion angle within range, causes the rack and pinion contact position local wear profile of tooth that links to each other to change, and drive mechanism jamming in the use produces the big cost of manufacture of weight, and the maintenance is loaded down with trivial details, and effective life is shorter.
The hydraulic reversible flagpole has the notice number CN210416892U, and hydraulic drive flagpole part equipment is various, and the reliability is lower, and it is big to occupy the space, heavy, with high costs, maintenance consuming time and wasting force.

A4, when the main pole 2 of the flagpole is erected: as shown in fig. 9, the flagpole main rod 2 and the hinge eye plate 201 are rotated upward relative to the guide plate 104 and the limit plate 105 around the rotation pin shaft 107 until the flagpole main rod 2 abuts against and is matched with the limit plate 105, and then the flagpole main rod 2 is erected to a preset position; the limit pin 106 is inserted into the hinge eye plate 201 and the guide plate 104. As shown in fig. 11, the supporting rod eye plate 1103 at the bottom of the supporting rod 11 is hinged to the fork head welded to the bulwark or the work platform and close to the base 1 by a fastener such as a bolt, so that the supporting rod 11 and the flagpole main rod 2 form an angle of 30 ° to 45 °. When the flagpole main rod 2 is erected for use, the moment generated by shaking the flagpole main rod 2 and most of the reaction moment acted on the hinged eye plate 201 by the limit pin 106 are offset; the moment provided by the support rod 11 further limits the shaking of the main pole 2 of the flagpole, so as to reduce the amplitude of the main pole 2 of the flagpole and weaken the adverse effect of fatigue stress.
A5, when the main pole 2 of the flagpole is laid down: as shown in fig. 10 and 11, the connection between the support rod eye plate 1103 at the bottom of the support rod 11 and the hull structure 13 is released, the limit pin 106 is removed from the hinge eye plate 201 and the guide plate 104, and the flag pole main rod 2 and the hinge eye plate 201 are rotated downward relative to the guide plate 104 and the limit plate 105 around the rotation pin 107 until the flag pole main rod 2 is laid down to a predetermined position; connecting a supporting rod eye plate 1103 at the bottom of a supporting rod 11 with a fork head which is welded and fixed on a bulwark or an operation platform and is far away from a base 1, wherein the angle between the supporting rod 11 and a flagpole main rod 2 is 30-45 degrees; the one end of the limiting rod 12 is connected with the limiting nut 10 through threads, the other end of the limiting rod is connected with the limiting base 1201 through threads, the limiting base 1201 is welded and fixed on a deck surface, the connecting points of the two support rods 11 and the limiting rod 12 and the ship structure 13 are distributed triangularly, and a triangular support is formed, so that when the flagpole main rod 2 is laid down, the flagpole main rod 2 is fixed, and the safety of a lamp on the flagpole main rod 2 is effectively guaranteed. In addition, when the main mast 2 is in a laid-down state, as shown in fig. 12, the top of the main mast 2 is lower than the base 1, so that the overall protruding height of the main mast 2 is reduced, the helicopter is favorable for taking off and landing, and the operation range of the outboard throwing object is expanded.
In conclusion, the present invention effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
