Example 2
Referring to fig. 1 to 10, a second embodiment of the present invention is different from the first embodiment in that: the second-stage damping member 204 includes a connecting rod 204a, a buffering rod 204b and a connecting seat 204c, the connecting seat 204c is fixed at the bottom of the damping table 201, the connecting rod 204a connects the two sets of supporting seats 202, a sliding sleeve 204d is slidably mounted on the connecting rod 204a, the sliding sleeve 204d is connected with the side wall of the supporting seat 202 through a compression spring 204e, and two ends of the buffering rod 204b are respectively hinged to the connecting seat 204c and the sliding sleeve 204 d.
When the ship is fluctuated, the fuel cell is shocked and impacted by the ship, and the damping table 201 carrying the fuel cell moves upwards or downwards. When the shock absorption platform 201 moves upwards, the connecting seat 204c at the bottom of the shock absorption platform 201 is driven to move upwards, so that the connecting rod 204a hinged to the connecting seat 204c is driven to move upwards, the connecting rod 204a moves upwards to pull the sliding sleeve 204d to move along the buffer rod 204b in the opposite direction, the compression spring 204e receives a pulling force, a first-level shock absorption buffering effect is achieved, and meanwhile, the shock absorption spring 203 connecting the shock absorption platform 201 and the supporting seat 202 also receives a pulling force, and a second-level shock absorption buffering effect is achieved. When the damping table 201 moves downwards, the connecting seat 204c at the bottom of the damping table 201 is driven to move downwards, so that the connecting rod 204a hinged to the connecting seat 204c is driven to move downwards, the connecting rod 204a moves downwards to push the sliding sleeve 204d to move along the buffer rod 204b in an opposite manner, the compression spring 204e receives pressure, a first-level damping buffering effect is achieved, and meanwhile, the damping spring 203 connecting the damping table 201 and the supporting seat 202 also receives pressure, and a second-level damping buffering effect is achieved. The two-stage damping and buffering effect of the compression spring 204e and the damping spring 203 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 bottom of the support base 202 is provided with a cavity 202a, a lifting piece 205 is arranged in the cavity 202a, and the lifting piece 205 is used for integrally lifting or one-side lifting the whole damping device when the ship is greatly fluctuated or inclined, so that the fuel cell is prevented from being greatly displaced or inclined relative to the ship body.
The top of the cavity 202a is provided with a magnetic block 202b, and the side wall of the support base 202 is provided with an accommodating cavity 202c communicated with the cavity 202 a. The lifting piece 205 comprises a magnetic insulation block 205a and a lifting base 205b which are arranged inside the cavity 202a, the magnetic insulation block 205a is located between the magnetic block 202b and the lifting base 205b, the magnetic insulation block 205a, the magnetic block 202b and the lifting base 205b are not in contact with each other, and the lifting base 205b and the magnetic block 202b are different in magnetism.
The magnetic insulation check block 205a is an iron block, the magnetic insulation check block 205a is positioned between the magnetic block 202b and the lifting base 205b, and the magnetic insulation check block 205a, the magnetic block 202b and the lifting base 205b are not in contact with each other, so that magnetic repulsion between the magnetic block 202b and the lifting base 205b can be effectively isolated, and the lifting base 205b is positioned in the cavity 202a under the action of gravity; when the magnetic insulation check block 205a is pushed into the accommodating cavity 202c under the action of external pressure, the magnetic insulation check block 205a has no separation effect on the magnetic repulsion between the magnetic block 202b and the lifting base 205b, and the lifting base 205b moves downwards along the cavity 202a under the action of the magnetic repulsion between the magnetic block and the lifting base, so that the damping device is lifted integrally or lifted on one side, and when the ship body is subjected to large fluctuation or inclination, the damping device is lifted integrally or lifted on one side, and the fuel cell is prevented from being subjected to large displacement or inclination relative to the ship body.
Further, a connecting spring 205a-1 fixed with the inner wall of the accommodating cavity 202c is arranged on one side of the magnetic insulation block 205a, the magnetic insulation block 205a can be ensured to be positioned between the magnetic block 202b and the lifting base 205b to separate the magnetic force of the magnetic block 202b and the lifting base 205b under the action of the connecting spring 205a-1, the magnetic insulation block 205a can be restored to an initial position after external pressure received by the magnetic insulation block 205a disappears, and a pressure rod 205a-2 extending to the outside of the cavity 202a is arranged on the other side of the magnetic insulation block 205 a. The lifting base 205b is movably mounted inside the cavity 202a by a slider. The two sets of opposite sliding sleeves 204d are connected with each other through a first connecting cross rod 204d-1, and a first support rod 204d-2 matched with the pressure rod 205a-2 is fixedly arranged on the first connecting cross rod 204 d-1.
When the ship is fluctuated, the fuel cell is shocked and impacted by the ship, and the damping table 201 carrying the fuel cell moves upwards or downwards. When the damping table 201 moves upwards, under the action of the gravity of the fuel cell and the buffering action of the compression spring 204e and the damping spring 203, the damping table 201 and the fuel cell thereon do not displace upwards for a large distance relative to the ship body, so that the fuel cell does not need to be prevented from displacing relative to other external devices connected to the ship, and the normal use of the fuel cell is affected. However, when the damping table 201 moves downward, the damping table 201 and the fuel cell thereon are likely to be displaced downward by a large distance relative to the hull under the gravity of the fuel cell itself, so that it is necessary to raise the damping table 201 and the fuel cell 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 in a normal state, the baffle keeps a small distance from the top surface of the shock absorbing platform 201, so that when the shock absorbing platform 201 moves upwards, the lifting base 205b fixed with the ship body directly falls from the cavity 202a, and the secondary shock absorbing member 204 and the shock absorbing spring 203 cannot perform the shock absorbing function.
When the shock absorbing table 201 receives a large impact and moves downwards for a large distance, the connecting seat 204c drives the connecting rod 204a to move downwards to push the sliding sleeve 204d to move oppositely along the buffering rod 204b, after the sliding sleeve 204d moves for a certain distance along the buffering rod 204b, the first support rod 204d-2 connected with the sliding sleeve 204d is abutted to the pressure rod 205a-2 of the magnetic insulation check block 205a, along with the continuous movement of the sliding sleeve 204d, the first support rod 204d-2 pushes the magnetic insulation check block 205a to move towards the inside of the accommodating cavity 202c, when the magnetic insulation check block 205a receives the pressure action of the first support rod 204d-2 and is pushed into the accommodating cavity 202c, the separation action of the magnetic insulation check block 205a on the magnetic repulsion between the magnetic block 202b and the lifting base 205b disappears, and under the action of the magnetic repulsion between the two, the lifting base 205b moves downwards along the cavity 202a, thereby integrally lifting the damping table 201 and the fuel cell thereon and preventing the fuel cell from generating large relative displacement relative to the ship body and externally connected equipment, thereby influencing the normal use of the fuel cell. When the impact force received by the shock absorption table 201 disappears, the sliding sleeve 204d is gradually restored under the action of the compression spring 204e, the external pressure received by the magnetic insulation check block 205a also gradually disappears, the magnetic insulation check block 205a is restored to the initial position under the action of the connection spring 205a-1, the magnetic repulsion between the magnetic block 202b and the lifting base 205b is cut off again, and the lifting base 205b returns to the inside of the cavity 202a again. It should be noted that the width of the accommodating cavity 202c is greater than the width of the magnetic-insulated check block 205a, so as to prevent the magnetic-insulated check block 205a from continuously moving after entering the accommodating cavity 202c, and thus prevent the secondary damping member 204 from continuously moving to cause failure thereof, and meanwhile, the connecting spring 205a-1 between the magnetic-insulated check block 205a and the inner wall of the accommodating cavity 202c can achieve the effect of tertiary damping and buffering, thereby further ensuring the mounting and damping performance and the loading stability of the fuel cell.
Further, two groups of pressure bars 205a-2 are arranged and respectively located at two ends of the magnetic-insulated check block 205a, and the two groups of pressure bars 205a-2 are connected with each other through a second connecting cross bar 205 a-3. An impact piece 205c is arranged between the connecting rods 204a through a fixing rod, the impact piece 205c comprises an impact pipeline 205c-1, a gravity ball 205c-2 and a second support rod 205c-3, the impact pipeline 205c-1 is formed by splicing an inclined downward pipe section and a parallel pipe section, the gravity ball 205c-2 is positioned at the lowest part of the inclined downward pipe section, and the second support rod 205c-3 is movably sleeved in the parallel pipe section and is connected with the middle part of the second connecting cross rod 205 a-3. The diameter of the second brace 205c-3 is smaller than the inner diameter of the impact pipe 205c-1, and an impact block is arranged at the end of the second brace 205c-3 away from the second connecting cross bar 205a-3 and 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 damping table 201 needs to be 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 205c-2 at the very bottom of the impact tube 205c-1 rolls along the tilted downward tube section into a parallel tube section, thereby generating gravity knocking on the second support rod 205c-3, the second support rod 205c-3 receives the knocking force of the gravity ball 205c-2, and pushes the second connecting cross rod 205a-3 connected with the second support rod to move towards the support seat 202, so that when the magnetic insulating block 205a is pushed into the accommodating cavity 202c under the pressure action of the second stay 205c-3, the magnetic insulating barrier 205a has no effect of blocking the magnetic repulsive force between the magnetic block 202b and the lifting base 205b, under the action of the magnetic repulsion between the two, the lifting base 205b moves down along the cavity 202a, thereby, the damping table 201 and the fuel cell thereon are lifted on one side, and the stability of the fuel cell is ensured. When the whole damping device tends to be smooth, the magnetic insulation block 205a is gradually restored under the action of the connecting spring 205a-1, so that the gravity ball 205c-2 positioned in the parallel pipe section is pushed to exit and reenter the inclined downward pipe section, and the gravity ball 205c-2 rolls to the lowest position along the inclined downward pipe section.
