[0018] like Figures 1 to 10 As shown, the present invention provides a marine lifeboat side release device, comprising a main body 1, a winch 2 is arranged on the surface of the main body 1, a support rod 22 is rotatably connected inside the main body 1, and a steel cable 3 at one end of the support rod 22 is wound on the surface of the winch 2; A fixing assembly, which is arranged at one end of the steel cable 3, and includes a housing 4; A lubrication mechanism is arranged at the top of the shell 4, and the lubrication mechanism includes an oil storage tank 8, which is fixedly connected to the top of the shell 4, and a liquid outlet pipe 9 located inside the shell 4 is fixedly installed on one side of the outer surface of the oil storage tank 8, and a fixed shell 10 is fixedly installed in the inner cavity of the oil storage tank 8, and a spring 11 is fixedly installed inside the fixed shell 10, and a sealing rod 12 located inside the fixed shell 10 is fixedly installed at one end of the spring 11, and a blocking block 13 located at one end of the liquid outlet pipe 9 is fixedly installed at one end of the sealing rod 12, and a connecting block 14 is fixedly installed on the top of the sealing rod 12, and a square shell 15 is fixedly installed on the top of the oil storage tank 8, and a screw rod 17 is slidably connected to the inside of the square shell 15, and an extrusion block 19 located at the top of the connecting block 14 is provided at the bottom end of the screw rod 17, and a gear 18 located on the surface of the screw rod 17 is rotatably connected to the bottom end of the square shell 15, and the screw rod 17 and the gear 18 are threadedly connected; The driving assembly is arranged on one side of the square housing 15 .

[0019] With the above solution, the operator sets the fixing components on both ends of the lifeboat, and when the lifeboat needs to be released, the winch 2 can be driven to rotate, so that the steel cable 3 is separated from the surface of the winch 2, and then the support rod 22 will rotate, and then the lifeboat will be driven to move to one side of the ship, and then the steel cable 3 will lift the lifeboat on the sea surface, and then the fixing components can be removed from the lifting ring of the lifeboat, thereby completing the release work; When the fixed component needs to be lubricated during long-term work, the driving component can be driven, and then the driving component will drive the gear 18 to rotate. Since the gear 18 is threadedly connected to the screw rod 17, when the gear 18 rotates, the screw rod 17 will move, and the screw rod 17 will push the extrusion block 19 to move, and then the bottom end of the extrusion block 19 will contact the top end of the connecting block 14, and will push the connecting block 14 to move, and the connecting block 14 will drive the sealing rod 12 to shrink into the inside of the fixed shell 10, and will squeeze the spring 11, and then the sealing rod 12 will drive the blocking block 13 to move, and the blocking block 13 will cancel the blockage of the liquid outlet pipe 9, and then the lubricating oil inside the oil storage tank 8 will enter the inside of the liquid outlet pipe 9, and the liquid outlet pipe 9 can lubricate the fixed component, and finally the blocking block 13 is cancelled by the driving component to block the liquid outlet pipe 9, and then the fixed component can be lubricated, thereby reducing the friction resistance of the fixed component, making the fixed component more flexible and smooth during operation, and improving the overall safety of the lifeboat releasing device.

[0021] The above scheme is adopted: through the design of the connecting rod 5, the hook 6 and the handle 7, the handle 7 can be pulled to rotate, and then one end of the handle 7 will contact the surface of the hook 6, and will push the hook 6 to rotate on the surface of the connecting rod 5, so that the lifeboat can be released and fixed, and when the lubricating oil flows out from the inside of the liquid outlet pipe 9, it will flow to the connection between the connecting rod 5 and the hook 6 and the connection between the handle 7 and the shell 4 respectively, so as to reduce the friction resistance between the various components.

[0022] like Figure 5 and Fig.10 As shown, the driving assembly includes a motor 20, which is fixedly connected to one side of the square shell 15, and a gear 21 meshing with the motor 20 is fixedly installed at the output end of the motor 20.

[0023] By adopting the above scheme: through the design of motor 20 and gear 2 21, motor 20 can be driven to rotate gear 2 21, because gear 2 21 is meshed with gear 1 18, and then the rotating gear 21 will drive gear 1 18 to rotate, thereby driving the lubrication mechanism to lubricate the fixed component.

[0024] like Figures 4 to 7As shown, it also includes: a swing mechanism, which is arranged at the top of the oil storage tank 8, the swing mechanism includes a gear three 23, the gear three 23 is rotatably connected to the top of the oil storage tank 8, a rack 24 is fixedly installed on the top of the extrusion block 19, a sliding ring 26 is arranged on one side of the gear three 23, a connecting block two 25 located inside the sliding ring 26 is fixedly installed on one side of the gear three 23, a connecting rod two 27 is fixedly installed on one side of the sliding ring 26, a toothed plate 28 is fixedly installed on one end of the connecting rod two 27, a gear four 29 is arranged on one side of the shell 4, and one side of the gear four 29 is fixedly connected to the handle 7.

[0025] The above scheme is adopted: through the design of the swing mechanism, when the extrusion block 19 squeezes the connecting block 14 to move, the extrusion block 19 can continue to be driven to descend, and then the extrusion block 19 will be linked to the rack 24 to move. When the rack 24 moves, the teeth on its surface will mesh with the teeth on the surface of the gear three 23, and then the moving gear three 23 will drive the connecting block two 25 to move inside the sliding ring 26, and the connecting block two 25 will drive the sliding ring 26 to move, and the sliding ring 26 will drive the connecting rod two 27 to move, and the connecting rod two 27 will drive the tooth plate 28 to move, because the tooth plate 28 is meshed with the gear four 29, and then the tooth plate 28 will drive the gear four 29 to rotate, and the gear four 29 will drive the handle 7 to rotate. When the handle 7 rotates, it will push the hook 6 to swing on the surface of the connecting rod one 5, and finally the handle 7 is swung by the extrusion block 19 linked to the rack 24, and then the handle 7 pushes the hook 6 to swing, so that the lubricating oil can be evenly distributed at the connection between the connecting rod one 5 and the hook 6 and the handle 7 and the housing 4, ensuring the effectiveness of lubrication.

[0026] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes: a shock absorbing mechanism, which is arranged inside the main body 1, and the shock absorbing mechanism includes a fixing rod 30, the fixing rod 30 is fixedly connected to the inside of the main body 1, and two sliders 31 are slidably sleeved on the surface of the fixing rod 30, and the two sliders 31 are elastically connected to the main body 1 on the opposite side with a spring 2 32 located on the surface of the fixing rod 30, and a shock absorbing block 33 is arranged on the top of the slider 31, and a hinge block 34 is fixedly installed on the bottom end of the shock absorbing block 33, and the hinge block 34 and the two sliders 31 are hinged through a hinge rod 35.

[0027] The above scheme is adopted: through the design of the shock-absorbing mechanism, when the support rod 22 rotates, its surface will contact the top of the shock-absorbing block 33, and then the shock-absorbing block 33 will be pushed down, and the shock-absorbing block 33 will drive the hinge block 34 to descend. Since the hinge block 34 and the slider 31 are hinged through the hinge rod 35, the hinge rod 35 will be pushed to rotate during the descent of the hinge block 34. The hinge rod 35 will push the slider 31 to move toward each other on the surface of the fixed rod 30, and then the moving slider 31 will squeeze the spring 2 32. Through the compression of the spring 2 32, the shock-absorbing block 33 can reduce the shock of the support rod 22 to prevent the impact generated when the support arm contacts the inside of the main body 1 from damaging its connecting parts, thereby extending its service life.

[0028] like Figure 4 and Figure 5 As shown, a fixing hole 36 is opened on the surface of the square shell 15, and a limiting block 37 located inside the fixing hole 36 is fixedly installed on the top of the gear 18, and the surface of the limiting block 37 is in contact with the inner wall of the fixing hole 36.

[0029] The above scheme is adopted: through the design of the fixing hole 36 and the limit block 37, when the gear 18 moves, the limit block 37 will be driven to move inside the fixing hole 36. Since the surface of the limit block 37 fits with the inner wall of the fixing hole 36, the gear 18 can be limited when the limit block 37 moves.

[0030] like Figure 5 and Figure 6 As shown, a slide groove 39 is provided inside the oil storage tank 8, and a limit block 40 is slidably connected inside the slide groove 39. One side of the limit block 40 is fixedly connected to the extrusion block 19. A stop block 38 located on the surface of the rack 24 is fixedly installed on the top of the oil storage tank 8. The rack 24 can move inside the stop block 38, and the stop block 38 is a trapezoidal design.

[0031] The above scheme is adopted: through the design of the slide groove 39 and the limit block 40, when the extrusion block 19 moves, the limit block 40 can be driven to move inside the slide groove 39, and then the moving limit block 40 can limit the moving direction of the extrusion block 19, and can ensure that the extrusion block 19 can move stably. Through the design of the stop block 38, when the rack 24 moves, it can move inside the stop block 38, and the stop block 38 is a trapezoidal design, which can block the lubricating oil and prevent the lubricating oil from flowing out from the connection between the oil storage tank 8 and the rack 24.

[0032] like Figure 5 and Figure 6As shown, a protective shell 2 41 is fixedly installed on the top of the oil storage tank 8, and the connecting rod 27 can move inside the protective shell 21, and a protective shell 16 located on the surface of the tooth plate 28 is fixedly installed on the surface of the shell 4, and square holes are provided at both ends of the protective shell 16, and the tooth plate 28 can move inside the square hole. The blocking block 13 is semicircular in design, and an arc groove is provided inside the oil storage tank 8, and the blocking block 13 can move inside the arc groove.

[0033] The above scheme is adopted: through the design of protective shell 2 41 and protective shell 1 16, since protective shell 2 41 is arranged on the top of the oil storage tank 8, protective shell 2 41 can protect the lubrication mechanism and the swing mechanism, and then protective shell 2 41 can also support connecting rod 27, and connecting rod 27 can support sliding ring 26, and protective shell 1 16 can protect tooth plate 28 and gear 4 29, and square holes are provided on both sides of protective shell 16, so that protective shell 1 16 will not interfere with the movement of tooth plate 28, and through the design of blocking block 13 and oil storage tank 8, since the blocking block 13 is semicircular in design, its blocking effect can be increased, and an arc groove is provided inside the oil storage tank 8, so that the oil storage tank 8 will not interfere with the movement of the blocking block 13.

[0034] The working principle and use process of the present invention: The operator sets the fixing assembly on both ends of the lifeboat, and when the lifeboat needs to be released, the winch 2 can be driven to rotate so that the steel cable 3 is separated from the surface of the winch 2, and then the support rod 22 will rotate.

Through the compression of the spring 2 32, the shock-absorbing block 33 can reduce the shock of the support rod 22, and then the lifeboat will be driven to move to one side of the ship, and then the steel cable 3 will lift the lifeboat on the sea surface, and then the fixing assembly can be removed from the lifting ring of the lifeboat, thereby completing the release work; When the fixed components need to be lubricated during long-term work, the motor 20 can be driven to rotate the gear 21, the gear 21 will drive the gear 18 to rotate, the screw rod 17 will move inside the gear 18, the screw rod 17 will push the extrusion block 19 to move, and then the extrusion block 19 will contact the connecting block 14 and push the connecting block 14 to move, the connecting block 14 will drive the sealing rod 12 and the blocking block 13 to move, and the blocking block 13 will cancel the blocking of the liquid outlet pipe 9, and then the lubricating oil inside the oil storage tank 8 will enter the inside of the liquid outlet pipe 9, and the liquid outlet pipe 9 can lubricate the connection between the connecting rod 1 5 and the hook 6 and the handle 7 and the housing 4; When the extrusion block 19 squeezes the connecting block 14 to move, the extrusion block 19 can continue to be driven down, and then the extrusion block 19 will link the rack 24 to move, and the teeth on its surface will mesh with the teeth on the surface of the gear three 23, and then the gear three 23 will drive the connecting block two 25 to move inside the sliding ring 26, and the connecting block two 25 will drive the sliding ring 26 to move, and the sliding ring 26 will drive the connecting rod two 27 and the toothed plate 28 to move, and then the toothed plate 28 will drive the gear four 29 to rotate, and the gear four 29 will drive the handle 7 to rotate.
