Description

Technical Field

[0001] The utility model relates to the technical field of waterside building protection, in particular to an impact buffer device used for a dock. Background Art

[0002] Ship collision with dock is a common marine accident, which may be caused by a variety of reasons, such as deviation from the route caused by operational errors and mechanical failures, or loss of control due to broken cables caused by strong winds and waves. The collision accident will not only damage the dock structure, but also affect the bridge crane equipment on the dock, and even cause the dock business to be interrupted, resulting in huge economic losses.

[0003] In the related technology, rigid pile structures are often constructed near the dock to block and withstand the impact of ships to avoid damage to the dock. However, when the tonnage of the ship is large or the water environment is complex and severe, the instantaneous energy of the ship's impact is huge, and the rigid pile structure is easily damaged and fails, making it difficult to provide sufficient protection.

[0004] Therefore, it is necessary to develop a new impact buffer device for docks to improve some of the above problems existing in the relevant technology. Utility Model Content

[0005] The utility model aims to provide an impact buffer device for a dock, which can reduce the instantaneous impact force generated by a ship collision and reduce the loss caused by the collision.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0008] Optionally, the buffer mechanism includes a transmission member and a hydraulic chamber, and the transmission member is respectively connected to the impact-bearing mechanism and the hydraulic chamber, and is used to convert mechanical energy generated by the impact of the impact-bearing mechanism into hydraulic energy.

[0009] Optionally, the buffer mechanism further includes a control valve, the hydraulic chamber is arranged in the water body, the interior of the hydraulic chamber is bidirectionally connected to the water body through the control valve, and the control valve makes the flow rate in the direction where the liquid flows into the hydraulic chamber greater than in the other direction.

[0010] Optionally, the control valve includes a blocking member, which is movably arranged in the channel between the hydraulic chamber and the water body, and the blocking member is provided with a through hole; when liquid flows out of the hydraulic chamber, the blocking member moves to block the channel, allowing the liquid to flow out through the through hole; when liquid flows into the hydraulic chamber, the blocking member moves to open the channel, allowing the liquid to flow in through the channel.

[0011] Optionally, the control valve further includes a blocking guide mechanism, in which at least two of the blocking members are movably arranged on the blocking guide mechanism, and are used to drive the blocking members to move and combine to form a conical structure when the liquid flows out of the hydraulic chamber, so as to block the channel with the blocking members.

[0012] Optionally, the apex of the conical structure points to the liquid outflow direction of the hydraulic chamber.

[0013] Optionally, the collision-bearing mechanism includes a rigid plate and an energy-absorbing rigid member, two rigid plates are arranged at intervals, the energy-absorbing rigid member is arranged between the rigid plates, and the energy-absorbing rigid member is honeycomb-shaped.

[0014] Optionally, the guide mechanism includes a slide rail and a support frame, the support frame is connected to the foundation, the slide rail is arranged on the support frame, the extension direction of the slide rail points to the dock, and the collision mechanism is movably arranged on the slide rail.

[0017] Compared with the prior art, the impact buffer device provided by the utility model has the following beneficial effects:

[0018] 1. The utility model arranges the collision bearing mechanism on the guide mechanism so that the collision bearing mechanism can move after being impacted, thereby avoiding direct rigid impact. Since a buffer mechanism is arranged between the foundation and the collision bearing mechanism, after the collision bearing mechanism moves, the buffer mechanism applies resistance to the collision bearing mechanism in the opposite direction of the impact force, prolonging the impact time, so that the energy of the impact is gradually dissipated, thereby reducing the peak value of the impact force.

[0019] 2. The utility model sets the hydraulic chamber in the water body beside the dock, so that the force generated by the collision can act on the liquid in the hydraulic chamber through the transmission member, and the control valve is used to adjust the flow rate of the liquid flowing out of the hydraulic chamber to apply resistance to the collision mechanism to reduce the instantaneous impact force. In addition, the control valve makes the flow rate of the liquid in the direction of flowing into the hydraulic chamber greater than that in the other direction. After the collision, the hydraulic chamber can absorb the liquid at a larger flow rate, which is convenient for the collision mechanism to return to its original position.

[0020] 3. The utility model arranges the blocking member movably on the blocking guide mechanism, and the blocking member has a partial conical contour surface, which can fully utilize the force of liquid flowing into or out of the hydraulic chamber to push the blocking member to move, so that at least two blocking members are combined to form a conical structure to block the channel or disperse and then conduct the channel, which is conducive to flexible change of the on-off of the control valve.

[0021] 4. The utility model forms a collision-bearing mechanism by arranging honeycomb-shaped energy-absorbing rigid parts between rigid plates, which has good strength. When the collision-bearing mechanism is impacted, the honeycomb structure can collapse and deform at the impact point to absorb the impact energy and reduce the energy acting on the foundation.

[0022] 5. The utility model provides strong support to the collision mechanism at various positions on its moving path by interconnecting the collision mechanism, the slide rail and the support frame.

[0023] 6. The utility model adds a stabilizing mechanism between the collision-bearing mechanism and the foundation, and arranges the stabilizing mechanism and the guiding mechanism on both sides of the buffer mechanism respectively, so that the collision-bearing mechanism can be supported by the stabilizing mechanism, the buffer mechanism and the guiding mechanism at least three positions in its height direction during the process of movement due to impact, thereby reducing the risk of overturning of the collision-bearing mechanism and enhancing the stability of the movement of the collision-bearing mechanism.

[0035] In some specific embodiments, the foundation 5 may be a pile foundation, such as a precast concrete pile, a steel pile or a cast-in-place pile.

[0036] In some specific embodiments, the foundation 5 is formed by square piles.

[0037] In some specific embodiments, referring to Figure 1 The collision mechanism 1 is a rectangular plate-shaped structure as a whole, and the collision mechanism 1 is arranged parallel to the edge contour of the dock 6.

[0038] In some specific embodiments, the buffer mechanism 3 may be a mechanism that utilizes a spring, an air cushion, or a polymer material to reduce impact and absorb vibration, and the present invention does not impose any limitation on this.

[0039] In some specific embodiments, the buffer mechanism 3 may utilize the flow of liquid to absorb impact energy.
