Description

Technical Field

[0001] The invention belongs to the technical field of icebreakers, and in particular relates to a ship icebreaker component and a use method thereof. Background Art

[0002] With the development of science and technology, people have expanded from land to sea, and the shipbuilding industry has become more and more developed, undertaking transportation between continents. However, the manufacture of ships is particularly difficult, especially icebreakers. To undertake icebreaking work, they currently use the method of adjusting the water level in the internal ballast tank to make the bow tilt up and down to crush the ice surface. Although this can break the ice, it will cause the equipment on the ship to sway left and right, especially scientific instruments, which are easily damaged, which is a great challenge to scientific research work. In addition, the existing icebreakers are special ship equipment that only undertake the task of breaking ice and have relatively single functions. Ordinary ships generally do not have icebreaking devices. When encountering ice, they can only rely on icebreakers to break the ice or passively wait for the ice to melt, which seriously affects the navigation of ships.

[0003] Some invention patents in the field of icebreaker technology are disclosed in the prior art, among which the invention patent with application number 201480069763.X discloses an icebreaker ship, which includes a hull with a bottom, a bow and a stern. The bow includes a forward-inclined upper bow, a lower bulbous bow and an intermediate bow. The ship is designed with a structural waterline W1, an upper icebreaking waterline W3 and a lower icebreaking waterline W2. In order to improve the icebreaking capability of the ship, when the ship is operating at the structural waterline W1 of the ship, the upper surface of the lower bulbous bow is arranged to be located at or near the water surface. When the ship is operating at the lower icebreaking waterline W2 of the ship, the lower surface of the lower bulbous bow is arranged to penetrate the water surface. When the ship is operating at the upper icebreaking waterline W3 of the ship, the forward-inclined upper bow is arranged to penetrate the water surface. The invention also relates to a method for operating the icebreaking vessel. The technical solution still has some shortcomings in its application. Currently, most technical methods for breaking ice use the vessel's own gravity and heavy objects to break the ice. However, due to the thick ice layer, it is difficult to break the ice layer simply by breaking the ice. The ice breaking efficiency is low, and breaking the ice with heavy objects requires a lot of energy consumption.

[0004] Based on this, the present invention designs a ship icebreaking component and a method of using the same to solve the above problems. Summary of the invention

A submersible motor is installed on the side end surface of the link rear seat, and the driving gear is fixedly sleeved on the submersible motor.

[0028] As a further description of the above technical solution:

[0029] An elastic connection component is connected between the link rear seat and the second lever member, and the elastic connection component includes a piston cylinder connected to the end of the second lever member, a piston rod is sleeved in the piston cylinder, and a support spring is connected to the end of the piston rod. The piston rod is elastically supported and connected to the inner end surface of the piston cylinder through the support spring, and the other end of the piston rod is connected to a connecting seat.

[0030] A method for using a ship icebreaking assembly comprises the following steps:

[0031] S1: The ship body breaks the ice layer on the water surface during the driving process, and controls the submersible motor and the hydraulic cylinder to work in sequence. The submersible motor drives the driving gear to rotate during the operation, and the driving gear transmits power to the driven gear through the toothed belt. The driven gear drives the ice breaking roller to rotate rapidly through the second transfer shaft;

[0032] S2: The hydraulic cylinder performs reciprocating motion during operation. During the retraction phase, the hydraulic cylinder rotates through the first adapter and the inner side of the first adapter frame, and generates a pulling force on the first adapter frame through the first adapter. During this process, the other end of the hydraulic cylinder rotates through the second adapter on the inner side of the second adapter frame through the second adapter. Under the action of the lateral pulling force, the first lever shaft slides on the first sliding block through the first sliding groove in the lever sleeve, and squeezes the first lever spring to cause it to undergo elastic deformation. The first lever shaft drives the first toothed plate to move on the toothed surface of the reversing gear. On the one hand, the first lever shaft drives the reversing gear to rotate through the first toothed plate, and on the other hand, the first lever shaft drives the lever sleeve to rotate around the first adapter shaft.

[0033] S3: During the rotation of the reverse gear, the second tooth plate will be pushed to slide to the other side, and the second tooth plate will drive the second lever shaft to slide on the second sliding block through the second sliding groove in the lever sleeve, and squeeze the second lever spring to make it elastically deformed. The second lever shaft pushes the ice-breaking assembly from bottom to top through the elastic support member. Before the ice-breaking roller contacts the bottom of the ice, the hydraulic cylinder stops the retraction movement. Under the action of the inertia of the ice-breaking assembly, the ice-breaking assembly extends in the piston cylinder through the piston rod, and pulls the support spring to make it elastically deformed.

[0034] S4: The ship body breaks the ice on the water surface during the driving process. In this process, the ship body presses down the ice on the water surface, and the stress of the ice on the water surface is concentrated near the ship body. The icebreaking roller impacts the bottom of the ice on the water surface there. It is suitable for a variety of ships and provides icebreaking function for ships with different functions.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0036] 1. In the present invention, the ship body breaks the ice layer on the water surface during the driving process. In this process, the ship body presses down the ice layer on the water surface, and the stress of the ice layer on the water surface is concentrated near the ship body. The ice-breaking roller impacts the bottom of the ice layer on the water surface at that location. The present invention is suitable for a variety of ships and provides ice-breaking function for ships with various functions. The ice-breaking effect is good, the ice-breaking efficiency is high, the installation is convenient, and the use is simple. The ice-breaking roller rotates rapidly when colliding with the ice bottom at that location. The ice-breaking roller cooperates with the ship body. Compared with the existing ice-breaking method using the hull and the traditional ice-smashing method, the ice-breaking efficiency is higher and it is more convenient to break ice in areas with thicker ice.

[0037] 2. In the present invention, before the ice-breaking roller contacts the bottom of the ice, the hydraulic cylinder stops retracting, and under the action of the inertia of the ice-breaking assembly, the ice-breaking assembly extends in the piston cylinder through the piston rod, and pulls the supporting spring to cause it to undergo elastic deformation, so that the ice-breaking roller and the hydraulic cylinder are elastically connected, which can weaken the recoil force generated when the ice-breaking roller collides with the bottom of the ice to a certain extent, thereby providing a certain degree of protection for the hydraulic cylinder. On this basis, the impact strength of the ice-breaking roller contacting the bottom of the ice can be increased by accelerating the working frequency of the reciprocating motion of the hydraulic cylinder.

[0065] A method for using a ship icebreaking assembly comprises the following steps:

[0066] S1: The ship body 1 breaks the ice layer on the water surface during the driving process, and controls the submersible motor 7054 and the hydraulic cylinder 503 to work in sequence. The submersible motor 7054 drives the driving gear 7053 to rotate during the operation, and the driving gear 7053 transmits power to the driven gear 7051 through the toothed belt 7052. The driven gear 7051 drives the ice-breaking roller 704 to rotate rapidly through the second transfer shaft 702;

[0067] S2: The hydraulic cylinder 503 performs reciprocating motion during operation. During the retraction phase, the hydraulic cylinder 503 rotates with the inner side of the first adapter frame 501 through the first adapter 502, and generates a pulling force on the first adapter frame 501 through the first adapter 502. During this process, the other end of the hydraulic cylinder 503 rotates on the inner side of the second adapter frame 504 through the second adapter. Under the action of the lateral pulling force, the first lever shaft 4031 slides on the first sliding block 4033 through the first sliding groove 4032 in the lever sleeve 402, and squeezes the first lever spring 4034 to cause it to undergo elastic deformation. The first lever shaft 4031 drives the first toothed plate 4035 to move on the toothed surface of the reversing gear 404. On the one hand, the first lever shaft 4031 drives the reversing gear 404 to rotate through the first toothed plate 4035. On the other hand, the first lever shaft 4031 drives the lever sleeve 402 to rotate around the first adapter shaft 401.

[0068] S3: During the rotation of the reverse gear 404, the second tooth plate 4054 is pushed to slide to the other side, and the second tooth plate 4054 drives the second lever shaft 4051 to slide on the second slide block 4055 through the second slide groove 4052 in the lever sleeve 402, and squeezes the second lever spring 4053 to make it elastically deformed. The second lever shaft 4051 pushes the ice-breaking assembly 7 from bottom to top through the elastic support member. Before the ice-breaking roller 704 contacts the bottom of the ice, the hydraulic cylinder 503 stops the retraction movement. Under the action of the inertia of the ice-breaking assembly 7, the ice-breaking assembly 7 extends in the piston cylinder 601 through the piston rod 602, and pulls the support spring 603 to make it elastically deformed.

[0069] S4: The ship body 1 breaks the ice layer on the water surface during the driving process. In this process, the ship body 1 presses down the ice layer on the water surface, and the stress of the ice layer on the water surface is concentrated near the ship body 1. The icebreaking roller 704 impacts the bottom of the ice layer on the water surface there. It is suitable for a variety of ships and provides icebreaking function for ships with different functions.

[0070] Working principle, when using:

[0071] The ship body 1 breaks the ice layer on the water surface during the driving process, and controls the submersible motor 7054 and the hydraulic cylinder 503 to work in sequence. The submersible motor 7054 drives the driving gear 7053 to rotate during the operation, and the driving gear 7053 transmits power to the driven gear 7051 through the toothed belt 7052. The driven gear 7051 drives the ice-breaking roller 704 to rotate rapidly through the second transfer shaft 702;

[0072] The hydraulic cylinder 503 performs reciprocating motion during operation. During the retraction phase, the hydraulic cylinder 503 rotates with the inner side of the first adapter frame 501 through the first adapter 502, and generates a pulling force on the first adapter frame 501 through the first adapter 502. During this process, the other end of the hydraulic cylinder 503 rotates on the inner side of the second adapter frame 504 through the second adapter. Under the action of the lateral pulling force, the first lever shaft 4031 slides on the first sliding block 4033 through the first sliding groove 4032 in the lever sleeve 402, and squeezes the first lever spring 4034 to cause it to undergo elastic deformation. The first lever shaft 4031 drives the first toothed plate 4035 to move on the toothed surface of the reversing gear 404. On the one hand, the first lever shaft 4031 drives the reversing gear 404 to rotate through the first toothed plate 4035. On the other hand, the first lever shaft 4031 drives the reversing gear 404 to rotate through the first toothed plate 4035. The rod shaft 4031 drives the lever sleeve 402 to rotate around the first adapter shaft 401. During the rotation of the reverse gear 404, the second tooth plate 4054 is pushed to slide to the other side. The second tooth plate 4054 drives the second lever shaft 4051 to slide on the second sliding block 4055 through the second sliding groove 4052 in the lever sleeve 402, and squeezes the second lever spring 4053 to make it elastically deformed. The second lever shaft 4051 pushes the ice-breaking assembly 7 from bottom to top through the elastic support member. Before the ice-breaking roller 704 contacts the bottom of the ice, the hydraulic cylinder 503 stops the retraction movement. Under the action of the inertia of the ice-breaking assembly 7, the ice-breaking assembly 7 extends in the piston cylinder 601 through the piston rod 602, and pulls the support spring 603 to make it elastically deformed, so that the ice-breaking roller 704 and the hydraulic cylinder 503 are elastically connected.

[0073] The ship body 1 breaks the ice layer on the water surface during the driving process. In this process, the ship body 1 presses down the ice layer on the water surface, and the stress of the ice layer on the water surface is concentrated near the ship body 1, and the ice-breaking roller 704 impacts the bottom of the ice layer on the water surface there.

3. A method for using the ship icebreaking assembly according to claim 2, characterized in that: The following steps are involved: S1: The ship body (1) breaks ice on the water surface during the travel, and controls the submersible motor (7054) and the hydraulic cylinder (503) to work in sequence. The submersible motor (7054) drives the driving gear (7053) to rotate during the operation. The driving gear (7053) transmits power to the driven gear (7051) through the toothed belt (7052). The driven gear (7051) drives the ice-breaking roller (704) to rotate rapidly through the second transfer shaft (702); S2: The hydraulic cylinder (503) performs reciprocating motion during operation. During the retraction phase, the hydraulic cylinder (503) rotates on the inner side of the first adapter frame (501) through the first adapter (502) and generates a pulling force on the first adapter frame (501) through the first adapter (502). During this process, the other end of the hydraulic cylinder (503) rotates on the inner side of the second adapter frame (504) through the second adapter. Under the action of the lateral pulling force, the first lever shaft (4031) is retracted from the lever sleeve (402). The first lever shaft (4031) drives the first toothed plate (4035) to move on the toothed surface of the reverse gear (404). On the one hand, the first lever shaft (4031) drives the reverse gear (404) to rotate through the first toothed plate (4035). On the other hand, the first lever shaft (4031) drives the lever sleeve (402) to rotate around the first transfer shaft (401). S3: During the rotation of the reverse gear (404), the second toothed plate (4054) is pushed to slide to the other side. The second toothed plate (4054) drives the second lever shaft (4051) to slide on the second sliding block (4055) through the second sliding groove (4052) in the lever sleeve (402), and squeezes the second lever spring (4053) to cause it to undergo elastic deformation. The second lever shaft (4051) pushes the ice-breaking assembly (7) to move from bottom to top through the elastic connection assembly (6). Before the ice-breaking roller (704) contacts the bottom of the ice, the hydraulic cylinder (503) stops the retraction movement. Under the action of the inertia of the ice-breaking assembly (7), the ice-breaking assembly (7) performs an extension movement in the piston cylinder (601) through the piston rod (602), and pulls the support spring (603) to cause it to undergo elastic deformation. S4: The ship body (1) breaks the ice layer on the water surface during the course of traveling. During this process, the ship body (1) presses down on the ice layer on the water surface, and the stress of the ice layer on the water surface is concentrated near the ship body (1), and the ice-breaking roller (704) impacts the bottom of the ice layer on the water surface.
