Description

Technical Field

[0001] The utility model relates to an anti-collision device for a ship, in particular to a detachable side anti-collision device. Background Art

[0002] When a ship is berthing, docking or sailing at sea, the side of the ship will inevitably collide with the side, especially when some special ships are performing salvage, rescue and supply. Therefore, it is particularly important to install anti-collision devices on the side of the ship. Figure 1 As shown, one or several fenders 1a are arranged on the side of the ship. The fenders of this structure are usually made of the same material as the hull structure and are connected to the hull by welding. The arrangement of multiple fenders will significantly increase the weight of the hull itself, and the arrangement of fenders below the waterline is equivalent to adding some underwater appendages, which will have a greater impact on the resistance and heading stability of the ship during navigation. There is another anti-collision structure such as using rubber fenders and laying sandwich anti-collision structures. This structure will also have a greater impact on the resistance and heading stability of the ship during navigation, and there are also a series of problems such as complex construction technology, high manufacturing cost, and inconvenient maintenance. After the anti-collision structure of the fender is damaged, the ship usually needs to be docked for repair, the maintenance cost rises sharply, the ship's operating time is shortened, and the economic loss is large. In addition, fenders, rubber fenders or sandwich anti-collision structures are usually set along the curved surface of the side outer plate. When special ships are lifting at sea, the hoisted objects are easily deviated from the predetermined position due to the influence of wind, waves and currents before leaving the water, and may even be caught in the propeller area at the rear of the ship, causing safety accidents. Utility Model Content

[0003] The utility model provides a detachable side anti-collision device, which can effectively solve the problem that the anti-collision device has an adverse effect on the navigation resistance and heading stability of the ship, and can also solve the risk of reducing the risk of the hoisted object being drawn into the propeller area at the rear of the ship during the lifting operation, thereby reducing the manufacturing and maintenance costs of the anti-collision device.

[0004] The detachable side anti-collision device described in the utility model comprises a fender material arranged along the side outer plate, wherein the fender material is provided with a plurality of circular holes along the length direction of the ship, and a cylinder is arranged in the circular hole and passes through the circular hole and extends into the water surface, and a column cap is arranged on the top of the cylinder for easy insertion and removal and abutting against the upper surface of the fender material for limiting position.

[0005] The detachable side anti-collision device can enclose the side and the propeller area at the rear of the ship by arranging a plurality of cylinders along the side, which not only plays an anti-collision role, but also effectively prevents the suspended objects from being drawn into the hull; the cylinder extends into the water surface, and since its cylindrical surface is a smooth arc surface, the interference to the water flow when the ship is sailing is very small, which effectively solves the problem that the anti-collision device has an adverse effect on the navigation resistance and heading stability of the ship; the column cap arranged on the top of the cylinder is fitted with the upper surface of the fender material for limiting, and the column cap can also be used to facilitate the insertion and removal of the cylinder, so that the cylinder can be disassembled at any time for convenient maintenance.

[0012] like Figure 2-6 As shown, a detachable side anti-collision device comprises a fender 2 arranged along the side outer plate 1, the fender is provided with a plurality of circular holes 3 along the length direction of the ship, a cylinder 4 is provided in the circular hole and extends into the water surface, and a column cap 5 is provided on the top of the cylinder for easy insertion and removal and against the upper surface of the fender for limiting position. By arranging a plurality of circular cylinders along the side, the side and the propeller area at the rear of the ship can be enclosed, which not only plays a role in anti-collision, but also effectively prevents the suspended object from being drawn into the hull; the cylinder extends into the water surface, and because its cylindrical surface is a smooth arc surface, the interference to the water flow is very small when the ship is sailing, which effectively solves the problem that the anti-collision device has an adverse effect on the sailing resistance and heading stability of the ship; the column cap arranged on the top of the cylinder can not only play a limiting role, but also facilitate the insertion and removal of the cylinder through the column cap, so that the cylinder can be disassembled at any time for convenient maintenance.

[0013] A number of circular holes are arranged on the fender along the ship direction, and the arrangement of the circular holes is determined according to the spacing of the cylinders. Furthermore, the column caps are connected to the cylinders as a whole by welding or threading.

[0014] If the fender is set too low on the side, it is inconvenient to place or withdraw the cylinder on the main deck. Therefore, in order to facilitate the insertion of the cylinder into the round hole of the fender or the withdrawal of the cylinder from the round hole of the fender, the upper surface of the fender is flush with the upper surface of the main deck 9.

[0015] The influence of waves on the water surface will cause the hull to shake, which will cause the cylinder to jump up and down relative to the fender. Therefore, a bolt 6 is further installed on the cylinder near the lower surface of the fender to prevent the cylinder from jumping up and down. The bolt passes through the cylinder, and the two ends of the bolt are abutted against the lower surface of the fender and cooperate with the column cap of the cylinder to limit the up and down jumping of the cylinder and avoid instability of the cylinder caused by the shaking of the hull.

[0016] Furthermore, in order to facilitate the insertion and removal of the cylinder, a lifting eye screw 7 is provided on the upper part of the column cap, and the lifting eye screw is screwed to the column cap through a thread.

[0017] After multiple insertions and withdrawals, the cylinder will cause great damage to the fender material. Moreover, the internal structure of the fender material is hollow. Therefore, a sleeve 8 is installed in the circular hole, and the cylinder is inserted into the sleeve. The edge of the sleeve is provided with a groove for easy welding. The sleeve can protect the fender material on the one hand, and support the fender material on the other hand.

[0018] The outer diameter of the cylinder is 1-2 mm smaller than the inner diameter of the sleeve, which facilitates the rapid insertion of the cylinder into the sleeve.
