Description

Technical Field

[0001] The utility model relates to the technical field of ship transportation, in particular to a gas tank positioning device for a natural gas transport ship. Background Art

[0002] Currently, LNG is typically transported from upstream loading ports to downstream LNG receiving terminals via LNG tankers. LNG is typically stored at atmospheric pressure and low temperatures in atmospheric pressure tanks with cold-insulation measures.

[0003] Traditional natural gas tankers navigate vast oceans, facing unpredictable winds, waves, and currents. The combined effects of these natural forces often cause the ship's hull to significantly rock and tilt. This unstable navigational state poses a significant safety threat to the natural gas tanks loaded on board. While the widely used natural gas tank positioning devices currently provide some degree of stability, their effectiveness is relatively limited. If a natural gas tank shifts or tilts due to insecure anchoring, it can not only pose a risk of leakage and endanger environmental safety, but can also damage the ship's structure, seriously impacting navigation safety and the lives of the crew. Utility Model Content

[0006] The gear train is connected with the gear axle of the first gear and the gear train is connected with the gear train of the second gear, and the gear train is connected with the gear train of the second gear to the said gear train.

[0007] Preferably, the moving block is connected to the limiting rod and is threadedly mounted on the surface of the bidirectional threaded rod. By rotating the bidirectional threaded rod, the moving block can only slide left and right inside the base under the limitation of the limiting rod.

[0008] Preferably, one end of the spring is connected to the connecting plate, and the other end of the spring is connected to the limiting plate, and a spring is provided for resetting the limiting plate.

[0009] Preferably, an anti-slip sleeve is provided on the inner side surface of the clamping plate, and the anti-slip sleeve is provided to increase the friction between the clamping plate and the natural gas tank, so that the clamping plate can better clamp and fix the natural gas tank.

[0010] Preferably, the gear belt is engaged with the first gear and the second gear at the same time, and the driving motor drives the second gear to rotate. Under the action of the gear belt and the first gear, the bidirectional threaded rod can be rotated.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a gas tank positioning device for a natural gas transport ship, comprising a base 1 and a clamping device 2, wherein the clamping device 2 is arranged inside the base 1, and a natural gas tank 3 is arranged on the top of the base 1.

[0021] The clamping device 2 is composed of a bidirectional threaded rod 201, a limiting rod 202, a moving block 203, a connecting plate 204, a sliding rod 205, a spring 206, a limiting plate 207, a clamping plate 208, a first gear 209, a fixing plate 210, a motor 211, a second gear 212, and a gear belt 213. The bidirectional threaded rod 201 is rotatably mounted on the inside of the base 1, the limiting rod 202 is fixedly mounted on the inside of the base 1, and the moving block 203 is slidably mounted on the surface of the limiting rod 202. A sliding groove matching the moving block 203 is opened inside the base 1. This setting allows the moving block 203 to be moved inside the base 1. The movable block 203 is connected to the limit rod 202 and is screwed on the surface of the two-way threaded rod 201. By rotating the two-way threaded rod 201, the movable block 203 can only slide left and right inside the base 1 under the limit of the limit rod 202. The connecting plate 204 is fixedly installed on the top of the movable block 203. The sliding rod 205 is slidably installed inside the connecting plate 204. The spring 206 is sleeved on the surface of the sliding rod 205. The limiting plate 207 is fixedly installed on one end of the sliding rod 205. One end of the spring 206 is connected to the connecting plate 204, and the other end of the spring 206 is connected to the limiting plate 207. Then, a spring 206 is provided for resetting the limit plate 207. The slide bar 205, the spring 206 and the limit plate 207 are all one group, which are distributed in a circular array on the side of the clamping plate 208. There are multiple groups of such components, which can better reset the clamping plate 208, thereby effectively preventing the clamping plate 208 from damaging the side of the natural gas tank 3. The clamping plate 208 is fixedly mounted on the other end of the slide bar 205. The inner side of the clamping plate 208 is provided with an anti-slip sleeve. The anti-slip sleeve is provided to increase the friction between the clamping plate 208 and the natural gas tank 3, so that the clamping plate 208 can be pressed against the natural gas tank 3. The gas tank 3 is better clamped and fixed, the first gear 209 is fixedly mounted on the surface of the bidirectional threaded rod 201, the fixing plate 210 is fixedly mounted on the top of the base 1, the motor 211 is fixedly mounted on the side of the fixing plate 210, the second gear 212 is fixedly mounted on the output shaft of the motor 211, and the gear belt 213 is sleeved on the surface of the second gear 212. The gear belt 213 is engaged with the first gear 209 and the second gear 212 at the same time. The driving motor 211 drives the second gear 212 to rotate. Under the action of the gear belt 213 and the first gear 209, the bidirectional threaded rod 201 can be rotated.

[0022] During use, the natural gas tank 3 is placed on the top of the base 1, and the driving motor 211 drives the second gear 212 to rotate. Under the action of the gear belt 213 and the first gear 209, the bidirectional threaded rod 201 can be rotated. Under the limit of the limit rod 202, the moving block 203 can only slide left and right inside the base 1, which can drive the connecting plate 204 to move. The natural gas tank 3 squeezes the clamping plate 208, so that the slide rod 205 drives the limit plate 207 to move. During the process, the spring 206 is stretched, so that the clamping plate 208 can clamp and fix the natural gas tank 3.
