Description

Technical Field

[0002] A floating dock is a large-scale water engineering building that can float on the water and is used to repair and build ships. It consists of dock walls on both sides and a box-shaped structure at the bottom, forming a concave building. The dock walls contain various chambers such as equipment rooms, drive rooms, control rooms, and living rooms.

[0003] In the prior art, the bottom structure of a floating dock includes a plurality of water tanks, which can be filled with water and drained when needed. When it is necessary to lift a ship, water is poured into the bottom water tanks to make the dock sink to a certain depth, and then the ship to be repaired is towed into the dock and fixed in position. The water in the water tanks is discharged through a powerful water pump in the dock, so that the dock gradually floats up, and the ship to be repaired is completely placed on the pier until the bottom of the dock is out of water.

[0004] When seawater enters the water tank, impurities carried in the seawater will settle inside the water tank, which needs to be cleaned regularly, which is time-consuming and laborious;

[0005] In addition, when pumping out water, seawater will remain in the water tank, which may cause corrosion inside the water tank over time.

The hull to be inspected is prone to rigid collision and extrusion with the floating dock, and the buffering protection when stopping is poor. Utility Model Content

The second limit telescopic rod 19 is arranged to disperse the impact force when the hull stops and prevent the electric push rod 18 from deformation.

[0045] In the utility model, the mounting seat 8 is rotatably mounted on the fixed seat 7, and is cooperated with a rotating motor 9, and the fixed seat 7 is movably arranged on the floating dock body 1. In this way, when not in use, the fixed seat 7 can be controlled to move to a suitable position on the floating dock body 1, and the mounting seat 8 can be controlled to rotate by the rotating motor 9, so that the direction of the fixed frame 10 and the buffer frame 11 changes. In this way, the overall space occupied in the width direction of the floating dock body 1 can be reduced, and the walking convenience on the surface of the floating dock body 1 can be improved.

[0046] See also Figure 1-Figure 6 As an implementation method of the mounting seat 8: an annular groove 16 is provided on the fixing seat 7 coaxially with the driving shaft of the rotating motor 9, and at least one set of limiting sliders 17 is symmetrically provided at the bottom end of the mounting seat 8 to cooperate with the annular groove 16.

[0047] Specifically, when the rotating motor 9 drives the mounting seat 8 to rotate on the fixed seat 7, the mounting seat 8 will drive the limiting slider 17 to rotate in the limiting slide groove. The cooperation between the limiting slider 17 and the limiting slide groove can improve the connection stability between the mounting seat 8 and the fixed seat 7, thereby improving the impact deformation resistance when the ship is stopped and improving the installation stability of the mounting seat 8 on the fixed seat 7.

[0048] See also Figure 1-Figure 6As an implementation of the fixed seat 7: a movable slider 20 is provided at the bottom end of the fixed seat 7, a movable slide groove 21 is provided on the floating dock body 1, the movable slider 20 is located in the movable slide groove 21, and a movable adjustment structure is provided between the movable slider 20 and the floating dock body 1;

[0052] Specifically, the inspection frame cover 24 and the protection lock 25 are provided to facilitate the inspection and replacement of the telescopic airbag 5 and the like, wherein the protection net 6 is provided corresponding to the inspection frame cover 24 .

[0053] In summary, when the overall equipment is in use:

[0054] The air pump 27 is controlled to deliver the gas to the ventilation cavity 4 in the installation frame 3 through the ventilation pipe 26, and then delivered to the inside of the telescopic airbag 5 through the ventilation cavity 4, so that the telescopic airbag 5 expands, thereby increasing the overall buoyancy of the floating dock body 1, so that the floating dock body 1 floats up. Conversely, the air pump 27 is controlled to extract the gas in the telescopic airbag 5, so that the buoyancy of the floating dock body 1 can be reduced, so that the floating dock body 1 sinks, so as to avoid corrosion of the floating dock body 1 by residual sediment during the process of pumping out seawater.

[0055] In the utility model, the telescopic airbag 5 is covered by the protective frame 2, so that the telescopic airbag 5 can be protected. The protective frame 2 adopts a grid structure, which is convenient for the infiltration and discharge of seawater in the protective frame 2, realizes the change of buoyancy, and can prevent the impact and damage of the telescopic airbag 5 from the outside, thereby improving the protective performance of the telescopic airbag 5.

[0056] At the same time, the utility model is provided with a protective net 6 inside the protective frame 2. The protective net 6 adopts a mesh structure with strong corrosion resistance. In this way, while ensuring that seawater flows into and out of the protective frame 2 smoothly, it can intercept debris in the seawater to prevent the debris from damaging the telescopic airbag 5, thereby improving the protective effect of the telescopic airbag 5 during use;

[0057] When the hull is parked on the floating dock body 1, the floating dock body 1 is controlled to sink so that the hull can enter the interior of the floating dock body 1;

[0058] During this process, the adjusting motor 23 is started, and the adjusting screw 22 can be controlled to rotate by the adjusting motor 23, so that the moving slider 20 moves in the moving slide groove 21, thereby realizing the movement and adjustment of the fixing seat 7 on the floating dock body 1. After adjusting to a suitable position, the operation of the adjusting motor 23 is stopped;

[0059] Control the rotating motor 9 to drive the mounting seat 8 to rotate on the fixing seat 7, so that the buffer frame 11 faces one side of the hull, and the position of the buffer frame 11 corresponds to the position of the hull;

[0060] Therefore, when the hull stops on the floating dock body 1, it will abut against the buffer frame 11 to achieve the stop limit. At the same time, the cooperation of the buffer spring 12 and the buffer rubber block 14 in the buffer assembly can reduce the impact of the impact force on the fixing frame 10, thereby improving the protection of the stop.

[0061] When the buffer rack 11 is not in use, the motor 23 can be adjusted to rotate, driving the movable slider 20 to move in the movable slide groove 21, so that the buffer rack 11 moves to the edge position of the floating dock body 1, and the steering of the buffer rack 11 can be controlled by rotating the motor 9 to reduce the space occupied by the buffer rack 11 and the fixed frame 10 in the middle of the floating dock body 1, thereby avoiding obstruction when walking inside the floating dock body 1.

Since the devices matched with the controller are commonly used devices, their control principles and line connections are all existing well-known and mature technologies, and their electrical connection relationships and specific circuit structures will not be elaborated here.
