In order to increase the buoyancy of the buoy body 1 on the water surface, a circle of floating bodies 12 are arranged on the periphery of the buoy body 1. The floating body 12 is made of a material that can float on the water surface. Furthermore, the periphery of the buoy body 1 and the upper part of the buoy body 12 are sleeved with the rubber ring 13, the diameter of the rubber ring 13 is smaller than or equal to that of the buoy body 12, the inner wall of the rubber ring 13 is fixed on the periphery of the buoy body 1 through the connecting columns 14 which are uniformly arranged in a plurality of, the air bags 15 are arranged between every two adjacent connecting columns 14, and the air bags 15 are fixed with the inner wall of the rubber ring 13 and the outer wall of the buoy body 1. It should be noted that: the rubber ring 13 can be fixed on the floating body 12 or can be directly placed on the floating body 12. The floating body 12 increases the contact surface of the buoy body 1 and water, so that the buoy body 1 can better grasp the water surface. Moreover, the rubber ring 13 and the air bag 15 are also arranged to increase the buoyancy of the buoy body 1 on the water surface, so that the buoy body 1 can better float on the water surface. Thus, even if the chain fixed at the bottom of the hemisphere 5 breaks, the navigation mark can well float on the water surface due to the floating body 12 and the air bag 15.

The top of the rotating shaft 19 is fixed with grooved wheels 21, one grooved wheel 21 is connected with a first motor 22 through a transmission belt, the grooved wheel 21 is also connected with the adjacent grooved wheel 21 through a belt, and the rest grooved wheels 21 are sequentially connected through the belt. The rotation shaft 19 is rotated by the first motor 22 and the other rotation shafts 19 connected by the belt are also rotated in the same direction so that the chain is wound around the rotation shaft 19.

Further, in order to prevent water from entering the target body 1 through the connecting column 14 in case of accident, a partition plate 34 is transversely arranged in the target body 1 and between the limiting plate 20 and the grooved pulley 21, and the rotating shaft 19 penetrates through the partition plate 34 and is connected with the partition plate 34 through a sealing bearing, so that the partition plate 34 cannot influence the rotation of the rotating shaft 19; meanwhile, the first motor 22 is disposed on the partition 34. At this time, in order to avoid water accumulation in the target body 1, the annular pad 32 is arranged at the bottom of the target body 1 around the fixed cylinder 23, the rotating shaft 19 is arranged on the annular pad 32, the annular pad 32 is inclined from the fixed cylinder 23 to the inner side wall of the target body 1, and the upper surface of the annular pad 32 is higher than or equal to the bottom of the third through hole. The annular pad 32 is fixed with the inner side wall of the target body 1 and the outer side wall of the cylindrical barrel 23, so that water entering the target body 1 enters the connecting column 14 through the third through hole to flow out, and the water is prevented from staying in the target body 1.

In order to enable the auxiliary mechanism in the connecting column 14 to be smoothly placed into the sea, a pushing mechanism is arranged in the tag body 1 and at a position symmetrical to the third through hole, the chain rolling mechanism is arranged on one side (beside) of the pushing mechanism, a fixed cylinder 23 is fixed at the axis of the tag body 1, the pushing mechanism comprises a pushing block 24 matched with the third through hole, a notch 25 for a chain to pass through is formed in the bottom of the pushing block 24, a push rod 26 is fixed at the center of one end of the pushing block 24 facing the interior of the tag body 1, the other end of the push rod 26 extends into the fixed cylinder 23, and the end of the push rod 26 extending into the fixed cylinder 23 is an inclined plane inclined towards the same direction; a second motor 27 is arranged in the fixed cylinder 23, the output end of the second motor 27 is fixed with deflector rods 28 with the same number as the push rods 26, the deflector rods 28 are arranged between two adjacent push rods 26 in a staggered manner, and the length of the overlapping part of the deflector rods 28 and the push rods 26 determines the length of the reciprocating motion of the pushing block 24; a return mechanism for reciprocating the push rod 26 is provided on the side wall of the fixed cylinder 23. In the present invention, the number of the shift levers 28 is preferably 4, the number of the push rods 26 is also 4, and the number of the connecting columns 14 is also 4.

It should be noted that: when the second motor 27 drives the shift lever 28 to rotate, the shift lever 28 slides on the inclined surface of the push rod 26, thereby moving the push rod 26. In order to allow the push rod 26 to return after moving out of the fixed cylinder 23, a return mechanism is provided on the outer wall of the fixed cylinder 23. When the push rod 26 moves out of the fixed cylinder 23, the push rod 26 carries the fixed plate 29 to stretch the first spring 30, and the reaction force of the stretched first spring 30 causes the push rod 26 to extend into the fixed cylinder 23, and finally the reset of the pushing mechanism is realized.

Furthermore, in order to reduce the gap between the chain and the notch 25, a rubber pad 36 is fixedly arranged on one side of the top of the notch 25, the rubber pad 36 inclines towards one side far away from the push rod 26, a second spring 35 is fixedly arranged on the back of the rubber pad 36, and the other end of the second spring 35 is fixed on the top of the notch 25. The rubber pad 36 has a certain ductility, and during the compression process of the second spring 35, the rubber pad 36 also moves along with the moving direction of the second spring 35. When the push rod 26 moves towards the connecting column 14, the rubber pad 36 presses the chain under the action of the second spring 35, and the other end of the rubber pad 36 is clamped on the chain (or abuts against the chain), so that the push block 24 pushes the chain into the connecting column 14; and when the push rod 26 moved in to the mark body 1 (push rod 26 resets), because the cushion 36 is smooth towards the one side of chain, very big reduction the frictional force between chain and the cushion 36, the chain also can compress the cushion 36 in addition, the chain has certain weight for the chain that is pushed away can not get back in the mark body 1 again. This is repeated to the extent that the chain in the connecting column 14 accumulates, which can dislodge the fluke 18 and plumb 16 from the connecting column 14 and eventually fall into the sea. The length of the chain connected to the anchor 18 is set according to the actual situation, with the anchor 18 capable of hooking the hook 33. Of course, the height of the hook 33 can be adjusted accordingly.

Further, a drop-in liquid level transmitter is fixed on the outer side of the floating body 12, the specific setting condition is set according to the actual condition, the liquid level change of the port is monitored in real time, the support frame 2 can be provided with a wind speed sensor and a visibility sensor, the devices are connected with a controller, and the controller monitors the water level and the wind power of the port, so that the controller controls the opening and closing of the first motor 22 and/or the second motor 27 and the running time. The visibility sensor determines the color of the beacon light 3 so that the ship sailing at sea can recognize the direction.

In the use process of the invention, when the controller monitors the conditions of water level rising (the water level rising is accompanied with sea waves, and sea waves cause certain impact on a navigation mark) and high wind speed of a port, the controller controls the second motor 27 to be started, so that the deflector rod 28 drives the push rod 26 to push a chain connected to the anchor hook 18 into the connecting column 14 by utilizing the push block 24; and start first motor 22 when second motor 27 starts, the rotation direction of first motor 22 is the opposite direction that the chain twines at pivot 19, withdraws from pivot 19 the chain for propelling movement piece 24 is more easy with the chain propelling movement to in the spliced pole 14, until the chain piles up behind certain degree in spliced pole 14 with fluke 18 and plummet 16 from spliced pole 14 extrusion, as to how long time second motor 27 operation can make fluke 18 fall into the sea, can obtain data according to the experiment. The rotational speeds of the first motor 22 and the second motor 27 are set according to actual conditions. It should be noted that: in order to avoid the chain that has been completely withdrawn from being rewound on the rotating shaft 19 after the first motor 22 has been operated for a long time, it is necessary to calculate the time taken for the chain on the rotating shaft 19 to be completely withdrawn when the rotating speed of the first motor 22 is constant, so as to control the rotating speed and the operating time of the first motor 22 by the controller.

When the anchor 18 has fallen into the sea, the anchor 18 is caused to move between several hooks 33 under the influence of the waves of the sea, so that the anchor 18 hooks onto the hooks 33.

Under such a severe environment, the target body 1 only rotates on the arc-shaped plate 7, and the target body 1 cannot fall down. Under the impact of sea waves and wind power, the chain at the bottom of the hemisphere 5 breaks the bolt 10 (the strength of the bolt 10 is set according to the actual situation) because the hemisphere 5 has a certain weight, and the chain in the cylindrical groove 9 is pulled out, so that the beacon body 1 rises, and the navigation beacon of the invention is changed from a fixed navigation beacon into a floating navigation beacon.

Even if the chains at the bottom of the hemispheroid 5 are broken after the sea waves reach certain strength, the anchor hooks 18 hook the hooks 33 in the process that the buoy body 1 is moved by the sea waves, so that the buoy is still at the original position. When the sea wave is removed and the water level is reduced, the navigation mark can be continuously used as a floating navigation mark, and certainly, the maintenance can be carried out, so that the hemispheroid 5 is placed on the arc-shaped plate 7 again, the chain is replaced, and the bolt 10 is inserted again. At this time, the anchor hook 18 is taken off from the hook 33, the first motor 22 is driven, the rotating shaft 19 is rotated, the chain is wound on the rotating shaft 19 again until the sealing post 17 is inserted into the second through hole, and the operation time and the rotation speed of the first motor 22 are set according to the length of the chain.
