[0030] REFERENCE Figures 1-3The utility model provides an embodiment: a ship anti -collision alarm mechanism based on radar response, including bottom plate 1, bottom plate 1 is the main support structure of entire anti -collision early warning mechanism, provides the installation foundation for subsequent other components, bottom plate 1 top fixedly connected with support rod 2, support rod 2 is used for providing the installation position for subsequent other components, the inside sliding connection of support rod 2 has moving rod 3, moving rod 3 can slide in support rod 2 inside, under certain circumstances can realize the height of radar body 7 adjustment effect, moving rod 3 is provided with tide prevention assembly, and the height of radar body radar body 7 is adjusted in time, ensures that radar can work stably under different water level conditions, and radar body 7 is installed at moving rod 3 top, and radar body 7 can detect the distance, direction, speed and other key information of target object in a certain range around ship in real time and accurately by emitting and receiving electromagnetic wave, and the inside of radar body 7 is provided with fixed component, and fixed component is used to stably fix radar body 7 on moving rod 3, so that sensing can also be carried out in harsh environment;

[0031] Referring to Figure 2 The tide prevention assembly includes a first limiting plate 4 and a buoyancy plate 6, the first limiting plate 4 is fixedly connected to the bottom of the moving rod 3, and the first limiting plate 4 is used for limiting the moving rod 3 to prevent the moving rod 3 from sliding out of the inside of the support rod 2, the buoyancy plate 6 is fixedly connected to the outer wall of the moving rod 3, when the tide comes, the buoyancy plate 6 will slide upward by buoyancy, further driving the moving rod 3 to slide, the first spring 5 is fixedly connected to the bottom of the first limiting plate 4, and the first spring 5 is used for reducing the impact generated by the contact between the buoyancy plate 6 and the top of the support rod 2 when the moving rod 3 is reset, and the damage caused to the radar body 7.

[0032] Referring to Figure 3 The fixed component includes a rotating shaft 9, the rotating shaft 9 is rotatably connected to the inside of the moving rod 3, the rotating shaft 9 is the main driving structure of the fixed component, two rope 10 on the outer wall of the rotating shaft 9 are wound by rotating the rotating shaft 9, the two rope 10 are fixedly connected to the second limiting plate 11 away from the rotating shaft 9, the second limiting plate 11 is used for limiting the clamping block 12 to prevent the clamping block 12 from sliding out of the inside of the moving rod 3, the clamping block 12 is fixedly connected to the second limiting plate 11 away from the rotating shaft 9, the clamping block 12 is fixed to the radar body 7 by clamping with the mounting plate 8, the second spring 13 is sleeved on the outer wall of the second limiting plate 11, the second spring 13 is used for providing elastic force to push the second limiting plate 11 to slide, further making the clamping block 12 and the mounting plate 8 clamped.

[0033] Referring to Figure 2The outer wall of the first limiting plate 4 is slidingly connected inside the supporting rod 2, so that the first limiting plate 4 can slide following the up-down sliding of the moving rod 3, which not only ensures the normal sliding of the moving rod 3 inside the supporting rod 2, but also does not hinder the movement of the moving rod 3. The bottom of the buoyancy plate 6 abuts against the top of the supporting rod 2, which ensures that when the moving rod 3 falls under the action of gravity during the ebb tide, the moving rod 3 can be limited by the abutment of the supporting rod 2 and the buoyancy plate 6.

[0034] With reference to Figure 3 The bottom of the radar body 7 is fixedly connected with two mounting plates 8, which provide a specific interface for the connection between the radar body 7 and the fixing assembly.

[0039] Working principle: when the early warning device is needed to warn the ship sailing to avoid the ship out of control and hit the wharf, the bottom plate 1 is installed at the distance of 200 meters from the sailing line of the wharf, then the rotating shaft 9 is rotated, when the rotating shaft 9 rotates, the rope 10 is wound, when the rope 10 is wound, the second limiting plate 11 is slid, the second limiting plate 11 slides, the clamping block 12 is slid, at the same time, the second spring 13 is extruded by the sliding of the second limiting plate 11, so that the second spring 13 stores potential energy, when the clamping block 12 completely slides into the moving rod 3, the radar body 7 is installed on the moving rod 3, and the mounting plate 8 and the clamping block 12 are at the same level, then the rotating shaft 9 is loosened, when the rotating shaft 9 is loosened, the external force disappears, the second spring 13 releases the stored elastic potential energy, so as to slide the second limiting plate 11, when the second limiting plate 11 slides, the clamping block 12 slides, so that the clamping block 12 is clamped with the mounting plate 8, the fixation of the radar body 7 is realized.

[0040] In the process of detection and early warning, when the tide rises, the buoyancy plate 6 slides upward under the action of buoyancy, when the buoyancy plate 6 slides, the moving rod 3 slides, so that the height of the radar body 7 changes, so as to prevent the water caused by the rising tide from damaging the radar body 7, when the tide recedes, the moving rod 3 slides downward under the action of gravity, and the first spring 5 at the bottom of the moving rod 3 buffers the falling of the moving rod 3.

[0041] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
