and all installation slots 1a are internally provided with damping mechanisms 2, which comprises 04336 a base 2a, a first fixing plate 2b, a second fixing plate 2c, a driving mechanism and a plurality of roller shafts 2g; the base 2a has a rectangular plate-like structure, and the first fixing plate 2b and the second fixing plate 2c are both located at two ends of the base 2a in a vertical state; the first fixing plate 2b and the second fixing plate 2c are both provided with through holes 2b1 matched with a protected tank 3, and annular damping rings 2b2 made of an elastic material are sleeved on the through holes 2b1 of both the first fixing plate 2b and the second fixing plate 2c; the driving mechanism is located on the first fixing plate 2b, the first fixing plate 2b and the second fixing plate 2c are both provided with a plurality of chutes 2b3 equidistantly surrounding the axis of the through hole 2b1, and all chutes 2b3 are arranged in a direction of the axis of the through hole 2b1 along the edges of the first fixing plate 2b and the second fixing plate 2c; all roller shafts 2g are located between the first fixing plate 2b and the second fixing plate 2c in a horizontal state, both ends of all roller shafts 2g are in sliding fit with the chutes 2b3 on the first fixing plate 2b and the second fixing plate 2c respectively in sequence, and all roller shafts 2g are in transmission connection with the driving mechanism.
Based on the above embodiment, when LNG is transported by transport vessel, the situation on the water surface is more complicated than when it is transported by land. When the ship hull 1 swings on both sides when it is transported on the water surface, the damping mechanism 2 in the prior art can only suppress the vibration, but not the swing of the ship hull 1, which may cause safety accidents. The technical problem to be solved in this application is how to protect the protected tank 3 on the transport vessel. Therefore, in this application, the protected tank 3 stored with liquefied natural gas is inserted into the through hole 2b1 of the first fixing plate 2b and the second fixing plate 2c, and at this time, the protected tank 3 is supported by the annular damping ring 2b2 in the through hole 2b1 of the first fixing plate 2b and the second fixing plate 2c, so that the sloshing when running on the water surface can be suppressed through the arrangement made of elastic materials, thereby achieving the damping effect. When the ship hull 1 swings on both sides, the protected tank 3 can only cling to the bottom of the through hole 2b1 under the action of gravity, and it can be damped by the damping ring 2b2, but it cannot cope with the swing of the ship hull 1. The driving mechanism drives all the roller shafts 2g to move in the direction of the chute 2b3, so that all the roller shafts 2g move along the edge of the first fixing plate 2b to the axis of the through hole 2b1, until all the roller shafts 2g are attached to the outer wall of the protected tank 3, so that the protected tank 3 is clamped on all the roller shafts 2g; the protected tank 3 is clamped on the axis of the through hole 2b1 through a plurality of roller shafts 2g, and the protected tank 3 can be driven to rotate in the plurality of roller shafts 2g through the arrangement of the plurality of roller shafts 2g. Because liquefied natural gas is stored in the protected tank 3, the gravity of the always drives the protected tank 3 to rotate in order to keep the liquid level of liquefied natural gas in the protected tank 3 to balance with the horizontal plane, so as to cope with the swinging of both sides of the ship hull 1, thereby preventing the occurrence of safety accidents caused by the shaking of the protected tank 3 in the device and effectively 04336 reducing the occurrence of vibration, thus avoiding the possibility of collision of the protected tank 3. When the swinging stops, all the roller shafts 2g are reset by the driving mechanism. Therefore, the protected tank 3 is continuously damped by the damping ring 2b2, and the damping mechanism 2 can cope with various vibrations or sloshing during transportation through the arrangement of the damping ring 2b2, the roller 2g and the driving mechanism, thus effectively avoiding the occurrence of safety accidents.
As shown in figures. 4 - 7 and 10, further: both ends of all roller shafts 2g are respectively sleeved with first sliding seats 2g1 and second sliding seats 2g3, and the first sliding seat 2g1 and the second sliding seat 2g3 are respectively connected with the chutes of the first fixing plate 2b and the second fixing plate 2c; racks 2g2 placed vertically are fixedly connected above all the first sliding seats 2g1, and driven shafts 2b5 rotating horizontally are arranged at the side of all the racks 2g2; the driven shafts 2b5 pass through the first fixing plate 2b, and all the driven shafts 2b5 are sleeved with first gears 2b6 and second gears 2b7; the first gears 2b6 and the second gears 2b7 are located at two sides of the first fixing plate 2b respectively, the first gear 2b6 is meshed with the rack 2g2, and all the second gears 2b7 are in transmission connection with the driving mechanism.
Based on the above-mentioned embodiments, the technical problem to be solved in this application is how the roller 2g slides in the sliding grooves 2b3 on the first fixing plate 2b and the second fixing plate 2c. Therefore, in this application, the roller shaft 2g is rotatably connected to the first sliding seat 2g1 and the second sliding seat 2g3 through the arrangement of the first sliding seat 2g1 and the second sliding seat 2g3 at both ends of the roller shaft 2g, so that the roller shaft 2g can rotate with the rotation of the protected tank 3; when the ship hull 1 swings, all the second gears 2b7 connected with it are driven to rotate by the driving mechanism. The rotation of the second gear 2b7 drives the rotation of the driven shaft 2b5 connected with it, and the rotation of the driven shaft 2b5 drives the rotation of the first gear 2b6 connected with it, which drives the movement of the rack 2g2 connected with it. Because the first sliding seat 2g1 is in sliding fit with the chute 2b3 of the first fixing plate 2b, the movement of the rack 2g2 drives the movement of the first sliding seat 2g1 fixedly connected with it. The movement of the first sliding seat 2g1 drives the roller shaft 2g connected with it, and the roller shaft 2g drives the the second sliding seat 2g3 on the other side to move , so that the roller shaft 2g moves along the sliding groove 2b3 of the first fixing plate 2b and the second fixing plate 2c.

Based on the above-mentioned embodiment, the technical problem to be solved in this application is how the driving mechanism drives the second gear 2b7 to rotate. Therefore, by starting the rotary driving motor 2f5, the output shaft of the rotary driving motor 2f5 drives the rotation of the rotary shaft 2f2 fixedly connected with it, and the rotation of the rotary shaft 2f2 drives the rotation of the third gear 2f3 connected with it; the rotation of the third gear 2f3 drives the rotation of the gear ring 2f1 meshed with it, so that the gear ring 2f1 rotates in the annular slide rail 2b8. Therefore, all the second gears 2b7 engaged with the gear ring 2f1 are driven to rotate, and all the driven shafts 2b5 are driven by the second gears 2b7, so that all the first gears 2b6 are driven, and the rack 2g2 drives the first sliding seat 2g1, the first sliding seat 2g1 drives the roller shafts 2g to move, so that all the roller shafts 2g can move along the sliding grooves 2b3 of the first fixing plate 2b and the second fixing plate 2c at the same time, which is convenient for all roller shafts 2g to clamp the protected tank 3.
As shown in figures 4 and 10, further: the tops of the first sliding seat 2g1 and the second sliding seat 2g3 are further fixedly connected by a connecting rod 2g4, and a support frame 2g5 is also arranged at the joint of two ends of the connecting rod 2g4 with the first sliding seat 2g1 and the second sliding seat 2g3.
Based on the above embodiments, the technical problem that this application wants to solve is how to make the first sliding seat 2g1 and the second sliding seat 2g3 synchronously drive the roller shaft 2g to move. Therefore, through the arrangement of the connecting rod 2g4, the movement of the first sliding seat 2g1 can drive the movement of the second sliding seat 2g3 in a synchronous belt, which is convenient for driving the roller shaft 2g to move along the chute 2b3 of the first fixing plate 2b and the second fixing plate 2c through the first sliding seat 2g1 and the second sliding seat 2g3; by the arrangement of the supporting frame 295, the connection strength between the first sliding seat 2g1 and the second sliding seat 2g3 is improved, so that the structure is more stable, which is convenient for the roller 2g to clamp the protected tank 3..

As shown in figure 10, further: one end of the arc-shaped plates 2g8 is provided with a sleeve 2g9, and the arc-shaped plates 2g8 on two adjacent connecting rods 2g4 can be sleeved together by the sleeve 2g9.
Based on the above-mentioned embodiments, the technical problem to be solved in this application is how to improve the damping effect of the arc-shaped plate 2g8. For this reason, in this application, through the arrangement of the sleeve 2g9, the arc-shaped plates 2g8 on a plurality of connecting rods 2g4 are sleeved together through the sleeve 2g9, so that the arc- shaped plates 2g8 on a plurality of connecting rods 2g4 are spliced into an annular frame, and the annular frame is attached to the inner wall of the protective cylinder 2d. When the ship hull 1 vibrates, the damping effect of the arc-shaped plates 2g8 can be improved through the annular frame, which can further inhibit the generation of vibration and avoid the occurrence of potential safety hazards.
As shown in figures 4 and 6, further: supporting feet 2b4 are arranged on two sides of the bottoms of the first fixing plate 2b and the second fixing plate 2c.
Based on the above-mentioned embodiments, the technical problem to be solved in this application is how to improve the supporting force of the first fixing plate 2b and the second fixing plate 2c on the base 2a. Therefore, by setting the supporting feet 2b4, the connection strength between the first fixing plate 2b and the second fixing plate 2c on the base 2a can be improved, and at the same time, more supporting force can be improved, so as to prevent the first fixing plate 2b and the second fixing plate 2c from being damaged and improve the stability of the device.
As shown in figures 8 and 9, further: a damping box 2e, a buffer block 2a1, a second elastic part 2a2, a plurality of sliders 2e2, a plurality of push rods 2e5 and a plurality of third elastic parts 2e4 are also arranged below the base; the damping box 2e is a rectangular box mechanism with an opening at the top, and the damping box 2e is sleeved at the bottom of the base 2a; the buffer block 2a1 has a square plate structure, and the buffer block 2a1 is fixedly connected to the centre of the bottom of the base 2a in a horizontal state; the second elastic part 2a2 is positioned at the bottom of the buffer block 2a1 and connected with the damping box 2e; the bottom of the damping box 2e is provided with a plurality of first slide rails 2e1 around a centre line thereof, and all the sliders 2e2 are slidably 504336 located on the first slide rails 2e1 in turn; one end of all the push rods 2e5 is pin-connected with the edge of the buffer block 2a1, the other end of all the push rods 2e5 is pin-connected with the top of the slider 2e2; all the sliders 2e2 are fixedly connected with mounting plates 2e3 placed in a vertical state, and all the third elastic parts 2e4 are respectively located between the mounting plates 2e3 and the inner side walls of the damping box 2e.
Based on the above-mentioned embodiments, the technical problem to be solved in this application is how the damping mechanism 2 suppresses vibration. Therefore, in this application, the buffer block 2a1 and the second elastic part 2a2 are arranged, so that the second elastic part 2a2 supports the base 2a, thereby reducing the generation of vibration, and has the function of absorbing vibration. Because the base 2a is sleeved in the damping box 2e, when the base 2a moves along the inner wall of the damping box 2e, the buffer block 2a1 moves, and the movement of the buffer block 2a1 drives the push rod 2e5 pin-connected with it. The movement of the push rod 2e5 drives the movement of the slider 2e2 which is pinned with it, so that the slider 2e2 moves in the direction of the first slide rail 2e1. Due to the arrangement of the third elastic part 2e4, the slider 2e2 can support the buffer block 2a1, which can further improve the shock absorption effect.
At the same time, the shock can be absorbed by a plurality of third elastic parts 2e4, which can improve the shock absorption effect.
As shown in figures 8 and 9, further: the four end corners of the base 2a are all provided with vertical buffer rods 2a3, all of which pass through the base 2a, and the buffer rods 2a3 are sleeved with fourth elastic parts 2a4, which are located between the base 2a and the damping box 2e.
Based on the above embodiment, the buffer block 2a1 is located in the centre of the base 2a, which may cause the base 2a to get stuck when sliding in the damping box 2e, thus affecting the damping effect on the base 2a. The technical problem to be solved in this application is how to better perform damping for the base 2a. Therefore, in this application, four buffer rods 2a3 and the second elastic part 2a2 can support the four end corners of the base 2a, so that the base 2a can slide in the damping box 2e more evenly, so that the base 2a is less likely to be stuck, and at the same time, the damping effect can be improved.
As shown in figures 4 and 8, further: the base 2a is further provided with an alarm component 2h, which comprises an alarm 2h1 and sensors 2h2 with one-to-one corresponding to the sliders 2e2, all the sensors 2h2 are fixedly connected to a plurality of sliders 2e2 in turn, and the alarm 2h1 is located at the top of the base 2a.
Based on the above-mentioned embodiments, the technical problem to be solved in this application is how the damping mechanism 2 can give early alarm to the workers. Therefore, the application detects the sliding displacement distance through the setting of the sensors 2h2.
When the displacement of a plurality of sliders 2e2 exceeds the set threshold, it will send an electrical signal to the back-end controller, and the controller at the back-end will send an electrical 04336 signal to the alarm 2h1, so that the alarm 2h1 will give a buzzer or a flashing light, so as to give an early warning and remind the workers to ensure that the protected tank 3 can be effectively protected.
