Description
Technical Field
The invention relates to the field of ships, and particularly discloses an LNG (liquefied natural gas) ship buffering and decelerating device.
Background
When a ship encounters an emergency situation during driving, the ship may collide with other ships, piers or large floating objects on water flow, or impact force is generated on a shell due to self gravity and speed when the ship is in shore, so that a buffering method is needed to reduce the speed of the ship and prevent the ship from being damaged when the ship is about to collide or is in shore.
Most of the existing buffering methods and devices play a role in buffering through the elasticity of springs, and in the spring buffering device, a part of force applied by a ship to the springs is rebounded by the ship in the buffering process, so that the ship shakes, is damaged and the like.

In view of the above, the present invention provides an LNG ship buffering and decelerating device to solve the technical problem of buffering and decelerating a ship.
In order to achieve the purpose, the invention provides the following technical scheme:
a buffering and speed reducing device for LNG ships comprises a base arranged at the stern and provided with an internal cavity, wherein two sides of the base are bent towards the side face of a ship body, two sides of the base are also communicated with hollow extension seats, end parts of two sides of the base are provided with driving cavities, the driving cavities are mutually independent from the inside of the base, a plurality of driving gear shafts penetrating through the driving cavities are vertically and rotatably arranged in the base, impellers and driving gears are arranged on the driving gear shafts, the driving gears are positioned in the base, the impellers are positioned in the driving cavities, the extension seats are provided with a plurality of plate grooves along the length direction, a first transmission rod is rotatably arranged in the extension seats along the length direction, a transmission device is arranged in the base, the transmission device can transmit the power of the driving gears to a first transmission rod, the first transmission rod is provided with a first worm wheel, and the extension seats are provided with a plurality of second transmission rods along the vertical direction, the second rotating rod is provided with a first worm, the first worm is meshed with the first worm wheel, one side of each plate groove is provided with a second transmission rod, the upper end and the lower end of each second transmission rod extend out of the extension seat and are fixedly provided with buffer plates, and the buffer plates can rotate out of the plate grooves. In this scheme, be provided with in the frame and can pivoted impeller, the effect of impeller produces power through rivers to drive the driving gear and rotate, the driving gear can drive first transfer line and rotate, and first transfer line drives the second transfer line again and rotates, and the second transfer line drives the buffer board and rotates, and the buffer board can receive great resistance under the rivers effect from the back of transferring out in the board groove, with the help boats and ships speed reduction.
Optionally, the lengths of both the plate channel and the buffer plate are tapered in a direction approaching the bow of the vessel. Being close to the bow direction more, the resistance that the buffer board received is big more, in this scheme, the buffer board length that is close to the bow is shorter, so the resistance that receives is less relatively, is difficult to damage, and the buffer board length at rear is longer simultaneously, and rivers can wash away on the buffer board at rear for this buffer board can play the effect of buffering deceleration, and it receives the resistance to diminish also difficult damage simultaneously.
Optionally, a water hole is arranged below the plate groove. The water hole can supply rivers to pass through, and the rivers that the buffer board blockked can follow the water hole and flow downwards to reduce the impact injury of rivers to the buffer board, avoid the buffer board impaired.
Optionally, a second worm is arranged on the first transmission rod, the transmission device comprises a plurality of transmission gears and a transmission shaft, the transmission shaft is rotatably arranged in the base, the transmission gears are arranged on the transmission shaft, the transmission gears are meshed with the driving gear, a second worm wheel is arranged on the transmission shaft, and the second worm is meshed with the second worm wheel. In the scheme, the second worm on the transmission shaft drives the second worm wheel and the first transmission rod to rotate, and the first transmission rod drives the second transmission rod to rotate.
Optionally, first transfer line includes long pole portion and a plurality of short pole portion, long pole portion is located the buffer board top that is closest to the frame, short pole portion is located all the other buffer board tops, and a buffer board corresponds a short pole portion, the both ends of long pole portion and short pole portion are equallyd divide and are provided with spread groove and connecting seat respectively, the connecting seat rotates with adjacent spread groove damping and is connected. Because the length of the first transmission rod is long, when the first transmission rod transmits torsional force, the rear end of the first transmission rod is insufficient in power, and the first transmission rod is likely to be subjected to torsional deformation and fracture. In this scheme, divide into long pole portion and a plurality of short pole portion with first transfer line, adopt the damping to rotate connected mode between long pole portion and short pole portion, short pole portion and the short pole portion, after power can't be transmitted on a certain short pole portion, relative rotation can take place for these two short pole portions, avoids the short pole portion to take place torsional deformation or the fracture condition, even a certain short pole portion is impaired also can change or maintain, can not influence whole first transfer line.
Optionally, a plurality of chain wheels are arranged on the second transmission rod, and a transmission chain is arranged between the chain wheels of the adjacent second transmission rods. In this scheme, provide new mode for second transfer line transmission power, adopt the chain mode to come the transmission can alleviate the transmission pressure of first transfer line for all second transfer lines homoenergetic rotate in step.
Optionally, the inner wall of the buffer plate closest to the base is in an inwardly concave arc shape. The inner wall of this buffer board is the arc and can increases its and rivers area of contact, and then increases the resistance, and rivers are also the power of second drive rod to all the other second transfer lines on this buffer board to the resistance of this buffer board, and the resistance is big more, and the drive power that all the other second transfer lines received is stronger, and all the other second transfer lines just can rotate and make the buffer board roll out.
The working principle and the beneficial effects of the scheme are that:
in this scheme, when boats and ships need the deceleration, open the drive cavity, rivers drive impeller rotates, and the impeller can drive first transfer line rotation as drive power, and first transfer line redrives the buffer board and opens and block rivers to obtain the resistance, reduce boats and ships speed of traveling. The decelerator in this scheme sets up in hull both sides, and when the ship normally travel, decelerator can not cause the influence to the ship.
