[0021] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] Please refer to Figure 1-5, the embodiments provided by the present utility model: a lifting device for a ship, which includes a moving component 1, a connecting component 2, a support rod 3 and a driving component 4. The moving component 1 includes a bottom plate 101. The connecting component 2 includes a mounting seat 201. The mounting seat 201 is made of stainless steel and is fixed on the deck by bolts. The deck is the surface of the hull and is prior art, so it will not be elaborated here. A notch 203 is formed in the middle of the mounting seat 201 for the bottom plate 101 to be clamped. The external dimensions of the bottom plate 101 are adapted to the internal dimensions of the notch 203. A railing 102 is fixedly provided at the top of the bottom plate 101 by welding to limit the displacement of the goods. A door 103 is rotatably connected to the side wall of the railing 102 by a hinge. Rotating the door 103 to open the railing 102 facilitates the loading and unloading of goods and improves the safety of goods transportation. A notch 205 is formed in the inner side wall of the notch 203. Two mounting boxes 202 are symmetrically fixed at the bottom end of the mounting seat 201. The mounting boxes 202 are sequentially communicated with the notch 205. A desiccant 206 is filled in the mounting boxes 202. A sealing component 5 is arranged inside the notch 205. The sealing component 5 includes a surface layer 501 clamped inside the notch 205. The surface layer 501 is made of rubber. A filler 502 is filled inside the surface layer 501. The filler 502 is made of sponge material and is porous. Both the surface layer 501 and the filler 502 are elastic, which improves the sealing performance of the clamping of the bottom plate 101 and prevents rainwater from penetrating. A plurality of through holes 503 are formed in the side wall and the inner side wall of the surface layer 501 close to the mounting box 202. The diameter of the through holes 503 is 1 mm. Under the capillary action, rainwater can be adsorbed into the mounting box 202 through the filler 502 and the through holes 503 to contact the desiccant 206, further reducing the leakage of rainwater, thereby reducing rainwater erosion and improving the service life of the device.

[0023] The top ends of the two groups of support rods 3 are symmetrically and rotatably connected to the bottom end of the bottom plate 101. The driving component 4 includes a base 401. The base 401 is buried in the inner bottom of the cabin. The bottom ends of the support rods 3 are rotatably connected with limiting rods 405. A bidirectional lead screw 406 is threadedly connected to the side walls of the limiting rods 405 through a lead screw slide. A servo motor 403 is fixed on the side wall of the base 401. The output end of the servo motor 403 is fixed at the end of the bidirectional lead screw 406, which improves the stability of the lifting of the bottom plate 101. A notch 402 is formed at the top end of the base 401 for the support rod 3 and the bottom plate 101 to be clamped. The internal dimensions of the notch 402 are adapted to the external dimensions of the bottom plate 101, which improves the convenience of storing the bottom plate 101. Two chutes 404 are symmetrically formed on the side wall of the base 401. The chutes 404 are communicated with the notch 402. The internal dimensions of the chutes 404 are adapted to the external dimensions of both ends of the limiting rod 405, which improves the stability of the horizontal movement of the limiting rod 405. Starting the servo motor 403 can drive the limiting rods 405 to slide horizontally towards each other, thereby driving the support rods 3 to rotate in the vertical direction, so that the bottom plate 101 can be lifted and lowered stably.

[0024] Both ends of the two mounting boxes 202 are slidably connected with cover plates 204. The cross-sections of the cover plates 204 are both convex-shaped, and anti-slip blocks are fixedly arranged on the side walls of the cover plates 204, which improves the convenience of replacing the desiccant 206.

[0025] Working principle: When this kind of lifting device for ships is in use, the operator first connects an external power supply. When the bottom plate 101 is clamped inside the first notch 203, the bottom plate 101 is flush with the deck surface. The operator can move the goods to the surface of the bottom plate 101 for lifting. The operator starts the servo motor 403 to drive the bidirectional lead screw 406 to rotate, thereby driving the bottom plate 101 to move vertically, which is convenient for transferring goods between the cabin and the deck. When there is rain on the surface of the deck, the operator lifts the bottom plate 101 to the top, so that the bottom plate 101 is clamped inside the first notch 203. The surface layer 501 is made of rubber, and a filler 502 is filled inside the surface layer 501. The filler 502 is made of sponge material and is porous. Both the surface layer 501 and the filler 502 have elasticity, which improves the sealing performance of the clamping of the bottom plate 101 to avoid rainwater penetration. A plurality of through holes 503 are provided on the side wall and the inner side wall of the surface layer 501 close to the mounting box 202. The diameter of the through holes 503 is 1 mm. Under the capillary action, the rainwater can be adsorbed into the mounting box 202 through the filler 502 and the through holes 503 to contact the desiccant 206, further reducing the leakage of rainwater, thereby reducing rainwater erosion and improving the service life of the device.

[0026] Secondly, when the desiccant 206 expires, the operator can open the mounting box 202 by pushing and pulling the cover plate 204, so as to facilitate the replacement of the desiccant 206 and ensure the dryness of the device.
