When the ship is fluctuated, the fuel cell is vibrated and impacted by the influence of the ship, and the support table 101 carrying the fuel cell moves upward or downward. When the supporting table 101 moves upwards, the connecting seat 203 at the bottom of the supporting table 101 is driven to move upwards, so that the connecting rod 201 hinged to the connecting seat 203 is driven to move upwards, the connecting rod 201 moves upwards to pull the sliding sleeve 204 to move towards each other along the buffer rod 202, the compression spring 205 receives a pulling force, a primary damping and buffering effect is achieved, and meanwhile, the damping spring 103 connecting the supporting table 101 and the supporting table 102 also receives a pulling force, and a secondary damping and buffering effect is achieved. When the supporting table 101 moves downwards, the connecting seat 203 at the bottom of the supporting table 101 is driven to move downwards, so that the connecting rod 201 hinged to the connecting seat 203 is driven to move downwards, the connecting rod 201 moves downwards to push the sliding sleeve 204 to move oppositely along the buffer rod 202, the compression spring 205 receives pressure to achieve a first-stage damping and buffering effect, and meanwhile, the damping spring 103 connecting the supporting table 101 and the supporting table 102 also receives pressure to achieve a second-stage damping and buffering effect. The two-stage damping and buffering effect of the compression spring 205 and the damping spring 103 can effectively reduce the vibration and impact received by the fuel cell, and ensure the mounting and damping performance and the loading stability of the fuel cell.
Further, the top of the cavity 102a is provided with a magnetic block 102b, and the side wall of the support base 102 is provided with an accommodating cavity 102c communicated with the cavity 102 a. The lifting piece 104 comprises a magnetic insulation block 104a and a lifting base 104b which are arranged inside the cavity 102a, the magnetic insulation block 104a is located between the magnetic block 102b and the lifting base 104b, the magnetic insulation block 104a, the magnetic block 102b and the lifting base 104b are not in contact with each other, and the lifting base 104b and the magnetic block 102b are different in magnetism.
The magnetic insulation check block 104a is an iron block, the magnetic insulation check block 104a is positioned between the magnetic block 102b and the lifting base 104b, and the magnetic insulation check block 104a, the magnetic block 102b and the lifting base 104b are not in contact with each other, so that magnetic repulsion between the magnetic block 102b and the lifting base 104b can be effectively isolated, and the lifting base 104b is positioned in the cavity 102a under the action of gravity; when the magnetic insulation check block 104a receives the external pressure and is pushed into the accommodating cavity 102c, the magnetic insulation check block 104a has no separation effect on the magnetic repulsion between the magnetic block 102b and the lifting base 104b, and the lifting base 104b moves downwards along the cavity 102a under the action of the magnetic repulsion between the magnetic block and the lifting base 104b, so that the damping device is raised integrally or raised on one side, and when the ship body is raised to have large fluctuation or inclination, the damping device is raised integrally or raised on one side, and the fuel cell is prevented from having large displacement or inclination relative to the ship body.
Further, a connecting spring 104a-1 fixed with the inner wall of the accommodating cavity 102c is arranged on one side of the magnetic insulation block 104a, the magnetic insulation block 104a can be ensured to be positioned between the magnetic block 102b and the lifting base 104b to separate the magnetic force of the magnetic block and the lifting base 104b under the action of the connecting spring 104a-1, the magnetic insulation block 104a can be restored to an initial position after external pressure received by the magnetic insulation block 104a disappears, and a pressure rod 104a-2 extending to the outside of the cavity 102a is arranged on the other side of the magnetic insulation block 104 a. The lifting base 104b is movably mounted inside the cavity 102a by a slider. The two sets of opposite sliding sleeves 204 are connected with each other through a first connecting cross rod 204a, and a first support rod 204b matched with the pressure rod 104a-2 for use is fixedly installed on the first connecting cross rod 204 a.
When the ship is fluctuated, the fuel cell is vibrated and impacted by the influence of the ship, and the support table 101 carrying the fuel cell moves upward or downward. When the support platform 101 moves upward, under the action of the gravity of the fuel cell and the buffering action of the compression spring 205 and the damping spring 103, the support platform 101 and the fuel cell thereon do not displace upward for a large distance relative to the ship hull, so that it is not necessary to prevent the fuel cell from displacing relative to other external devices connected to the ship, thereby affecting the normal use of the fuel cell. However, when the support table 101 is moved downward, the support table 101 and the fuel cells thereon are likely to be displaced downward by a large distance relative to the hull under the weight of the fuel cells themselves, so that it is necessary to raise the support table 101 and the fuel cells thereon appropriately in this case. It should be noted that, the ship body is provided with a baffle (not shown) at the installation position of the shock absorbing device, and the baffle is normally spaced from the top surface of the supporting platform 101 by a small distance, so as to prevent the lifting base 104b fixed to the ship body from directly falling from the cavity 102a when the supporting platform 101 moves upwards, and the shock absorbing assembly 200 and the shock absorbing spring 103 cannot perform the shock absorbing function.
When the support 101 receives a large impact and moves downwards for a large distance, the connecting seat 203 drives the connecting rod 201 to move downwards to push the sliding sleeve 204 to move reversely along the buffer rod 202, after the sliding sleeve 204 moves for a distance along the buffer rod 202, the first stay 204b connected with the sliding sleeve 204 abuts against the pressure rod 104a-2 of the magnetic grid stopper 104a, along with the continuous movement of the sliding sleeve 204, the first stay 204b pushes the magnetic grid stopper 104a to move towards the inside of the accommodating cavity 102c, and when the magnetic grid stopper 104a is pushed into the accommodating cavity 102c under the pressure action of the first stay 204b, the magnetic grid stopper 104a has no separation action on the magnetic repulsion between the magnetic block 102b and the lifting base 104b, and under the action of the magnetic repulsion between the magnetic block and the magnetic block, the lifting base 104b moves downwards along the cavity 102a, so that the support 101 and the fuel cell thereon are integrally lifted, and the fuel cell is prevented from large relative displacement relative to the externally connected equipment, thereby affecting the normal use of the fuel cell. When the impact force received by the support table 101 disappears, the sliding sleeve 204 gradually returns under the action of the compression spring 205, the external pressure received by the magnetic insulation check block 104a also gradually disappears, the magnetic insulation check block 104a returns to the initial position under the action of the connection spring 104a-1, the magnetic repulsion between the magnetic block 102b and the lifting base 104b is cut off again, and the lifting base 104b returns to the inside of the cavity 102a again. It should be noted that the width of the accommodating cavity 102c is greater than the width of the magnetic insulating barrier 104a, so as to prevent the magnetic insulating barrier 104a from moving after entering the accommodating cavity 102c, and thus the shock-absorbing assembly 200 cannot move continuously to cause failure thereof, and meanwhile, the connecting spring 104a-1 between the magnetic insulating barrier 104a and the inner wall of the accommodating cavity 102c can achieve a three-level shock-absorbing and buffering effect, so as to further ensure the mounting shock-absorbing performance and the loading stability of the fuel cell.
Further, two groups of pressure levers 104a-2 are arranged and respectively located at two ends of the magnetic insulation check block 104a, and the two groups of pressure levers 104a-2 are connected with each other through a second connecting cross rod 104 a-3. The connecting rods 201 are provided with the impact piece 104c through the fixing rods, the impact piece 104c comprises an impact pipeline 104c-1, a gravity ball 104c-2 and a second support rod 104c-3, the impact pipeline 104c-1 is formed by splicing an inclined downward pipe section and a parallel pipe section, the gravity ball 104c-2 is positioned at the lowest part of the inclined downward pipe section, and the second support rod 104c-3 is movably sleeved in the parallel pipe section and is connected with the middle part of the second connecting cross rod 104 a-3. The diameter of the second stay 104c-3 is smaller than the inner diameter of the impact pipe 104c-1, the end of the second stay 104c-3 away from the second connecting cross bar 104a-3 is provided with an impact block 104c-4, and the impact block 104c-4 is positioned at the splicing position of the inclined downward pipe section and the parallel pipe section.
When the hull is greatly inclined and the whole damping device is caused to be greatly inclined, the support table 101 is raised on one side to ensure the stability of the fuel cell. When the entire shock absorbing device is tilted to one side, the gravity ball 104c-2 at the very bottom of the impact tube 104c-1 rolls along the tilted downward tube section into a parallel tube section, thereby generating gravity knocking on the second support rod 104c-3, the second support rod 104c-3 receives the knocking force of the gravity ball 104c-2, pushes the second connecting cross rod 104a-3 connected with the second support rod to move towards the supporting seat 102, so that when the magnetic insulating block 104a is pushed into the accommodating cavity 102c under the pressure action of the second stay bar 104c-3, the magnetic insulating barrier 104a has no effect of blocking the magnetic repulsive force between the magnetic block 102b and the lifting base 104b, under the action of the magnetic repulsion between the two, the lifting base 104b moves down along the cavity 102a, so as to raise the support table 101 and the fuel cell thereon at one side, and ensure the stability of the fuel cell. When the whole damping device tends to be smooth, the magnetic insulation block 104a is gradually restored under the action of the connecting spring 104a-1, so that the gravity ball 104c-2 positioned in the parallel pipe section is pushed to exit and enter the inclined downward pipe section again, and the gravity ball 104c-2 rolls to the lowest position along the inclined downward pipe section.
Further, the bottom of the supporting table 101 and the top of the supporting base 102 are provided with spring positioning columns, the supporting table 101 and the supporting base 102 are connected with the damping springs 103 through the spring positioning columns, and three groups of damping springs 103 are arranged at equal intervals along the length direction of the supporting base 102.
