Problems solved by technology

[0007] (1) The active anti-collision design in the prior art is a relatively complex system engineering. Whether the design scheme can be successful depends on various factors such as the quality of people, technical level, funds, etc., and the implementation requirements are too high
[0008] (2) In the prior art, the artificial islands occupy a lot of water surface and change the original water flow environment of the channel; in order to prevent water damage, the artificial islands are generally relatively rigid and have great destructive power to ships. Risk of running aground
[0009] (3) The independent type in the prior art will also change the water flow environment and occupy the water-passing area in actual use. It is only suitable for bridge projects with shallow water levels, good foundation conditions, and no obstruction to navigation after installation. The destructive power to the hull is still small during use. very big
[0010] (4) In the prior art, when the pier is hit by a ship in the attached type, the anti-collision components will be damaged to varying degrees, cannot be automatically reset, and lose their protective function. It will take a lot of time and money to maintain and reinforce or rebuild
[0013] 2) The amount of underwater construction involved is large and the investment is large. At present, the lack of funds is still the main problem encountered in bridge ship collision protection
[0014] 3) Due to the narrowness of the inland river, the anti-collision facilities are not allowed to occupy more space and hinder the normal navigation of ships

Abstract

The invention belongs to the technical field of safety protection of underwater facilities, and discloses a pier anti-collision system capable of resetting automatically and a method, the pier anti-collision system capable of resetting automatically is provided with a pier, an anti-collision unit and a buoyancy tank are assembled around the pier through a frame panel, and a pulley structure is arranged between the pier and the frame panel; the anti-collision unit is provided with a second steel plate welded to the first steel plate, and a rotating shaft seat is fixed to the upper side of the first steel plate; the rotating shaft seat is connected with a compression inclined cylinder through a rotating shaft, and an inclined rod is sleeved with the compression inclined cylinder and connected with a rotating strip through the rotating shaft seat; a spring is wound on the compression inclined cylinder and the inclined rod, and a baffle is arranged at the lower end of the compression inclined cylinder and connected with the spring. The pier anti-collision system focuses on energy dissipation, compresses the elastic rod pieces after collision to obtain flexible buffering, increases resistance borne by a ship, slows down the speed, enables the ship to be far away from a pier after the anti-collision component releases elastic energy, can effectively prevent collision, and protects the safety of the ship to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of underwater facility safety protection, and in particular relates to an automatic resettable pier anti-collision system and method. Background technique [0002] At present, the development of highway transportation has prompted the construction of more and more bridges across rivers and rivers. The development of waterway transportation has increased the flow of ships, but at the same time, the large-scale ships have posed a serious threat to the safety of bridges. The probability is obviously increased. Once the ship loses control or deviates from the channel and hits the bridge, it is very easy to cause vicious accidents such as bridge collapse and ship capsizing, with disastrous consequences. [0003] The anti-collision method is conceptually divided into active anti-collision and passive anti-collision design. Active anti-collision is to avoid ship collision with the bridge through navigation manageme...
