Its beneficial effect is that under the action of the compression spring, the L-shaped guide sliding rod can drive the U-shaped block to move downward and tightly clamped on the mounting frame.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] See also Figure 1-6 A high-performance combined anti-collision buoyancy box provided by an embodiment of the present invention includes a box body 1 floatingly arranged on the side of a building, and also includes: an anti-collision plate 2, which is arranged on the side of the box body 1 away from the building; a feed-back layer 3, which is connected and arranged between the box body 1 and the anti-collision plate 2; a water cavity 4, which is arranged in the box body 1 and is used to store a certain amount of water; a balance cavity 5, which is arranged at the junction of the box body 1 and the anti-collision plate 2, and the height is lower than the water cavity 4; a guide component, which is arranged in the box body 1, and is used to guide the water in the water cavity 4 into the balance cavity 5 when the anti-collision plate 2 is squeezed and pushed, so as to lower the center of gravity of one side of the anti-collision plate 2.

[0023] Specifically, the box 1 is preferably made of high-density polyethylene material, and the interior is hollow or porous in cross-section, which retains buoyancy and increases strength; the box 1 itself has a certain elastic recovery force to resist impact; a positioning rod 6 is installed on the side of the building, and a connecting ear 7 is provided on the box 1, and the connecting ear 7 is hinged on the positioning rod 6; the length of the positioning rod 6 is adapted to the building, and multiple boxes 1 are combined and connected on the same positioning rod 6 to form a continuous protection; when the center of gravity of the box 1 is at its own center, it can float horizontally, and when the center of gravity shifts to the side away from the building, the box 1 rotates to reduce the height of the side away from the building, and the top surface of the box 1 forms an inclined surface. The anti-collision plate 2 is preferably a high-performance composite material with higher strength and better wear resistance, which is mainly used to receive the impact of ships. The feed-back layer 3 has a certain elasticity, and after exceeding the tolerance range of the elastic strength, plastic deformation and compression occur. The water cavity 4 is set in the middle position close to the center of gravity of the box 1, thereby maintaining the horizontal state of the box 1 when it floats freely. The outer side of the balancing chamber 5 is surrounded by a box body 1, a shrinkage layer 3 and an anti-collision plate 2 which are connected in sequence. When the shrinkage layer 3 is compressed, the volume of the balancing chamber 5 changes accordingly. After the volume of the balancing chamber 5 changes, it is similar to the volume of the water chamber 4. The height of the balancing chamber 5 is lower, which is convenient for the water chamber 4 to guide the flow into the balancing chamber 5. The setting of the guide component controls the water in the water chamber 4 to be smoothly and timely introduced into the balancing chamber 5 when needed after the buoyancy box is subjected to a strong collision; and when the buoyancy box is not collided or only slightly bumped, the water capacity in the water chamber 4 is maintained. In actual use of the present technical solution, after the anti-collision plate 2 suffers an impact that is difficult to block, the feed-back layer 3 will be squeezed to trigger the guide component, which then guides the water stored in the water cavity 4 into the balance cavity 5 of a lower height, thereby causing the center of gravity of the entire pontoon to shift toward the anti-collision plate 2. The floating height of the anti-collision plate 2 on the side close to the building is maintained, while the height on the other side is reduced, thereby forming an inclined surface on the upper surface of the box body 1, and then guiding the near side of the approaching ship obliquely upward, causing the ship to tilt slightly, and the center of gravity of the ship deviates to the side away from the building, thereby obtaining a better buffering effect and improving the safety of the device.
