[0035] Working principle: When a support structure of a ship fuel tank is in use, in the initial state, the fixing plate 101 is fixed at the bottom of the base 1. The fixing block 102 installed on the fixing plate 101 is provided with an installation hole 103 for fixing the base 1. A threaded rod 202 is rotatably connected in the chute 2 and the inner groove 201 opened on the base 1 through a motor 203. The threaded rod 202 is connected to an adjusting seat 302 slidably connected in the inner groove 201. A side clamping frame 303 is connected to the top of the adjusting seat 302. Both ends of the side clamping frame 303 are supported by rollers 306 and a clamping mechanism 4 is also connected to the upper surface, so as to adjust the distance between the two clamping mechanisms 4 to realize the clamping and fixing of fuel tanks of different lengths. Anti-slip pads 406 are arranged on the inner sides of the first clamping arm 403 and the second clamping arm 405 which are sequentially connected through the first rotating shaft 402 and the second rotating shaft 404 on the support 401. A first telescopic cylinder 409 and a second telescopic cylinder 412 are respectively connected to the first clamping arm 403 and the second rotating shaft 404, so as to control the first clamping arm 403 and the second clamping arm 405 to rotate inwards or expand to clamp and fix fuel tanks of different sizes;

[0036] When it is necessary to clamp and fix fuel tanks of different sizes, first, the first telescopic cylinder 409 and the second telescopic cylinder 412 contract to pull the first clamping arm 403 and the second clamping arm 405 to rotate and expand outwards. Then, the fuel tank is hoisted onto the two supports 401 and fixed in contact with the anti-slip pads 406. At this time, first start the first telescopic cylinder 409 to extend. The extended first telescopic cylinder 409 pushes the first clamping arm 403 and the first upper hinge seat 408 to rotate inwards around the first rotating shaft 402 under the support and limit of the first lower hinge seat 407, so that the first clamping arms 403 on both sides move inwards to contact and clamp the fuel tank. Then start the second telescopic cylinder 412 to push the second clamping arm 405 and the second upper hinge seat 411 to rotate inwards around the second rotating shaft 404 under the support and limit of the second lower hinge seat 410, so that the second clamping arm 405 moves inwards gradually to contact the outer wall of the fuel tank for clamping and fixing. At this time, both ends of the fuel tank are in a semi-wrapped clamping state to complete the fixing. This device is convenient for clamping and fixing fuel tanks of different sizes.

[0037] When it is necessary to clamp and fix fuel tanks of different lengths, first measure the distance between the clamping and fixing points at the left and right ends of the fuel tank, and then start the telescopic ejector rod 308 to contract and pull the anti-slip clamping plate 309 out from the bottom of the lock plate 310 to release the lock. At this time, the motor 203 drives the threaded rod 202 to rotate, and uses the thread groove 311 to push the two sets of adjusting seats 302 and the sliding seat 301 to move inward or outward to the inner sides of both ends of the base 1 under the sliding support of the runner 306, and drives the clamping mechanism 4 to move accordingly to adjust the distance. It is okay until the distance between the two sets of clamping mechanisms 4 is the same as the pre-measured distance between the fixed points. After the adjustment is completed, the telescopic ejector rod 308 extends to push the anti-slip clamping plate 309 into the lock plate 310 to lock the positions of the sliding seat 301 and the clamping mechanism 4. This device is convenient for clamping and fixing fuel tanks of different lengths.
