Description

Technical Field

[0001] The utility model relates to the technical field of navigation marks, in particular to an anti-collision protection device for navigation marks. Background Art

[0002] A navigation mark is the abbreviation of a navigation mark, which refers to a mark indicating the direction, boundaries and obstacles of a waterway, including river crossing marks, coastal marks, guide marks, transition guide marks, bow and stern guide marks, side marks, left and right navigation marks, position marks, flood marks and bridge and culvert marks, etc. It is an artificial mark that helps guide ships to navigate, locate and mark obstacles and indicate warnings. In the prior art, when a navigation mark is used, it is generally directly exposed on the water surface, and the bottom is limited by a sinker connected to an anchor chain. Since there is no protective mechanism on the outside of the navigation mark itself, when a collision occurs with a passing ship and a large collision force is generated, the navigation mark will be damaged, thereby shortening its service life. Therefore, in view of the above problems, an anti-collision protection device for a navigation mark is proposed. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0011] 1. An anti-collision protection device for a navigation mark, which is provided with a stopper rod, a bracket, a pressure block, a buffer spring, a control switch, an electric push rod, a tooth block, a gear, a reel and an anchor chain.

Based on the specific implementation methods in the utility model, all other specific implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown, an anti-collision protection device for a navigation mark comprises a navigation mark 1, a controller 2 is fixedly connected to the outer side of the navigation mark 1, a photovoltaic panel 3 is fixedly connected to the top of the outer side of the navigation mark 1, a fixed box 11 is fixedly connected to the bottom end of the navigation mark 1, a fixed shaft 12 is rotatably connected to the inner side of the fixed box 11, a reel 13 is fixedly connected to the outer side of the fixed shaft 12, an anchor chain 14 is fixedly connected to the outer side of the reel 13, and the anchor chain 14 passes through the fixed box 11, the anchor chain 14 is slidably connected to the fixed box 11, a sinker 15 is fixedly connected to the bottom end of the anchor chain 14, a gear 16 is fixedly connected to the left end of the outer side of the fixed shaft 12, a tooth block 17 slidably connected to the fixed box 11 is meshed on the outer side of the gear 16, an electric push rod 18 is fixedly connected to the inner side of the tooth block 17, and the electric push rod 18 is fixedly connected to the fixed box 11.

[0021] Example 2

[0022] like Figure 1-2As shown, in order to solve the problem that it is inconvenient to perform buffering protection on the device when the collision force of the ship on the device is small, a baffle rod 4 is provided at the bottom end of the outer side of the navigation mark 1, and a bracket 5 is fixedly connected to the outer side of the baffle rod 4, and the bracket 5 is slidably connected to the navigation mark 1, and one end of the bracket 5 is fixedly connected to a push block 6 slidably connected to the navigation mark 1, and a rotating rod 7 is rotatably connected to the outer side of the push block 6 through a rotating shaft, and the other end of the rotating rod 7 is rotatably connected to a pressure block 8 slidably connected to the navigation mark 1 through a rotating shaft, and a buffer spring 10 is fixedly connected to the bottom end of the outer side of the pressure block 8, and the other end of the buffer spring 10 is fixedly connected to the navigation mark 1. When the collision force between the ship and the device is small, the baffle rod 4 pushes the push block 6 through the bracket 5, and the rotating rod 7 further pushes the pressure block 8 to compress the buffer spring 10, which is convenient for buffering protection of the device when the collision force of the ship on the device is small.

[0023] Example 3

[0024] like Figure 2 As shown, in order to solve the problem that it is inconvenient to release the positioning of the fixed shaft 12 in the reel 13 when the collision force of the ship on the device is large, a control switch 9 is provided at the bottom of the pressure block 8, and the control switch 9 is fixedly connected to the pressure block 8. When the collision force of the ship on the device is large, the pressure block 8 compresses the buffer spring 10 and triggers the control switch 9, which further controls the electric push rod 18 to contract, thereby driving the tooth block 17 to disengage from the gear 16, which facilitates the release of the positioning of the fixed shaft 12 in the reel 13.

[0025] Example 4

[0026] like Figure 3 As shown, in order to solve the problem that it is inconvenient to reduce the friction between the anchor chain 14 and the fixed box 11 when the anchor chain 14 is retracted and released, a protective cover 19 made of ceramic material is fixedly connected to the bottom end of the inner side of the fixed box 11, and the anchor chain 14 passes through the protective cover 19, and the anchor chain 14 is slidably connected with the protective cover 19. By making the anchor chain 14 contact with the fixed box 11 through the protective cover 19 made of ceramic material, the friction between the anchor chain 14 and the fixed box 11 when the anchor chain 14 is retracted and released is reduced by utilizing the smooth property of ceramic.

[0027] Example 5

[0028] like Figure 2-3As shown, in order to solve the problem of the inconvenience of automatically resetting the position of the device when the ship leaves the collision point, a clockwork spring 20 is fixedly connected to the right end of the outer side of the fixed shaft 12, and the other end of the clockwork spring 20 is fixedly connected to the fixed box 11, and a fixed block 21 is fixedly connected to the bottom end of the outer side of the anchor chain 14, and a reset switch 22 in contact with the fixed box 11 is fixedly connected to the top of the fixed block 21. When the ship leaves the collision point, the reel 13 is driven by the fixed shaft 12 to rewind the anchor chain 14 under the recovery of the elastic force of the clockwork spring 20. After the anchor chain 14 is completely rewound, the fixed block 21 is pulled to trigger the reset switch 22, so that the electric push rod 18 is further reset to re-push the tooth block 17 to mesh with the gear 16 to position the reel 13 on the outer side of the fixed shaft 12, which facilitates the position of the automatic resetting device when the ship leaves the collision point.

[0029] In this embodiment, when a serious collision occurs with a ship during the use of the device, the blocking rod 4 that collides pushes the push block 6 through the corresponding bracket 5, and further pushes the pressure block 8 to compress the buffer spring 10 through the rotating rod 7, so that the device can be buffered when the collision occurs. When the collision force is large, the buffer spring 10 is further compressed by the pressure block 8, and the pressure block 8 further triggers the control switch 9. The controller 2 will control the electric push rod 18 to retract, thereby driving the tooth block 17 to disengage from the gear 16. At this time, after the device is collided, the anchor chain 14 will continue to rotate out from the outside of the reel 13, and the reel 13 will continue to drive the fixed As the shaft 12 rotates, the clockwork spring 20 will continue to shrink, and the device will continue to move away from the collision position, thereby avoiding damage to the device when the collision force is large. When the colliding ship leaves the navigation mark 1 after the collision, the fixed shaft 12 is controlled to drive the reel 13 to rewind the swung out anchor chain 14 under the recovery of the elastic force of the clockwork spring 20. After the anchor chain 14 is completely rewound, the fixed block 21 is pulled to trigger the reset switch 22, which further resets the electric push rod 18 and re-pushes the tooth block 17 to engage with the gear 16 to position the reel 13 outside the fixed shaft 12, which facilitates the automatic resetting of the device after the device is pushed away.
