[0032] Embodiment 1

[0033] Refer to Figure 1 、 3 、4, 7, 8, which is the first embodiment of the present invention, providing an auxiliary boarding device for an offshore wind power operation and maintenance ship. This device includes

[0034] A folding mechanism 100, including a lifting tower 101, a lifting part 102 provided on the lifting tower 101, a groove part 103 provided on the lifting part 102, a storage part 104 provided on the groove part 103, a pressing part 105 provided in the storage part 104, an erecting part 106 provided on the pressing part 105, and a power part 107 provided in the groove part 103;

[0035] A compensation mechanism 200, including a guiding part 201 provided on the lifting part 102 and a compensation part 202 provided on the storage part 104.

[0036] During use, the power part 107 is started to drive the storage part 104 to move along the groove part 103. The movement of the storage part 104 pushes the pressing part 105 to move the erecting part 106 out and rotate it upright, thereby protecting the staff. At the same time as the storage part 104 moves, it drives the compensation part 202 to move. Due to the setting of the guiding part 201, the compensation part 202 rotates when moving, thereby compensating for the height of the fence on the wind power tower.

[0037] Embodiment 2

[0038] Refer to Figures 1 to 7 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the lifting part 102 includes a lifting plate 102a arranged on the lifting tower 101, a boarding plate 102b arranged on the lifting plate 102a, and a hydraulic telescopic rod 102c arranged between the lifting plate 102a and the boarding plate 102b.

[0039] Preferably, a power system is arranged inside the lifting tower 101 to drive the lifting of the lifting plate 102a, so as to control the height of the boarding plate 102b, enabling the device to be applicable to wind power towers of different heights, increasing the applicability of the device. And when the boarding plate 102b rises to a high position, the boarding plate 102b is folded through the hydraulic telescopic rod 102c, thereby storing the boarding plate 102b, reducing the influence of sea breeze on the boarding plate 102b, and increasing the service life of the device and the stability of the hull.

[0040] The tank part 103 includes a side groove 103a arranged on the boarding plate 102b, a telescopic groove 103b arranged on the boarding plate 102b, a limiting groove 103c arranged on the boarding plate 102b, and a removal groove 103d arranged on the boarding plate 102b.

[0041] Preferably, the side grooves 103a are arranged on both sides of the boarding plate 102b for storing the storage plate 104a. The storage plate 104a is slidably connected to the side grooves 103a to ensure that the storage plate 104a can move. The telescopic groove 103b is used for installing the power part 107, and the telescopic groove 103b is communicated with the side grooves 103a, so that the power part 107 can be connected to the storage plate 104a, thereby driving the storage plate 104a to move and ensuring the normal operation of the device. The limiting groove 103c is used for installing the limiting slider 105d to limit the extrusion part 105, so that the extrusion part 105 can only move out along the limiting groove 103c to ensure the normal operation of the device. The setting of the removal groove 103d enables the compensation part 202 to move out along the removal groove 103d to prevent jamming and ensure the normal operation of the device.

[0042] The storage part 104 includes a storage plate 104a arranged in the side groove 103a, a storage groove 104b arranged on the storage plate 104a, a wing plate 104c arranged on the boarding plate 102b, an erection groove 104d arranged on the wing plate 104c, and an erection rack 104e arranged on the erection groove 104d.

[0043] Preferably, the storage plate 104a is slidably arranged in the side groove 103a and is used for storing the protection vertical rod 106c, reducing the occupied space of the device. A plurality of storage grooves 104b are provided and are arranged in a parallelogram. If the storage grooves 104b are arranged in a rectangle, the first extrusion block 105a cannot be pushed to move along the direction of the limiting groove 103c;

[0044] The wing plate 104c is installed at the top of the side of the boarding plate 102b, making the teeth of the erecting rack 104e face downward, so that the erecting gear 106b can rotate clockwise along the erecting rack 104e, ensuring that the protection vertical rod 106c rotates and erects upward. The wing plate 104c is used for installing the erecting rack 104e, and at the same time shields and protects the erecting rack 104e, and also shields the storage groove 104b to reduce the entry of rainwater and increase the service life of the device. The setting of the erecting groove 104d provides space for the protection vertical rod 106c to rotate and erect. The setting of the erecting rack 104e enables the erecting gear 106b to rotate when moving along the erecting rack 104e, so as to drive the protection vertical rod 106c to erect and ensure the normal operation of the device.

[0045] The extrusion part 105 includes a first extrusion block 105a arranged in the storage groove 104b, an extension rod 105b arranged on the first extrusion block 105a, a second extrusion block 105c arranged on the extension rod 105b, a limiting slider 105d arranged on the first extrusion block 105a and adapted to the limiting groove 103c, a first inclined surface 105e arranged on the first extrusion block 105a and adapted to the storage groove 104b, and a second inclined surface 105f arranged on the second extrusion block 105c and adapted to the storage groove 104b.

[0046] Preferably, the first extrusion block 105a is slidably arranged in the storage groove 104b. The setting of the first inclined surface 105e, combined with the parallelogram setting of the storage groove 104b, the inclined surface of the storage groove 104b extrudes the first inclined surface 105e so that the first extrusion block 105a can move along the inclined surface of the storage groove 104b, thus ensuring the normal operation of the device, and the first inclined surface 105e is adapted to the inclined surface of the storage groove 104b. The extension rod 105b is used for installing the second extrusion block 105c;

[0047] The second inclined surface 105f on the second extrusion block 105c is adapted to the inclined surface on the other side of the receiving groove 104b. When the receiving groove 104b moves in the reverse direction, it can push the second inclined surface 105f to make the second extrusion block 105c move in the reverse direction, so that the protective vertical rod 106c can be reset to ensure the normal operation of the device. At the same time, due to the setting of the second inclined surface 105f, when the receiving plate 104a is stationary, if the first extrusion block 105a moves, the first extrusion block 105a drives the extension rod 105b to make the second extrusion block 105c extrude the inclined surface of the receiving groove 104b. The limit of the receiving groove 104b on the second extrusion block 105c makes the first extrusion block 105a unable to move, preventing the protective vertical rod 106c from being randomly removed and ensuring the stability of the device.

[0048] The erecting part 106 includes an erecting rotating shaft 106a arranged on the first extrusion block 105a, an erecting gear 106b arranged on the erecting rotating shaft 106a and adapted to the erecting rack 104e, a protective vertical rod 106c arranged on the erecting rotating shaft 106a, and a protective cross rod 106d arranged on the protective vertical rod 106c.

[0049] Preferably, the erecting rotating shaft 106a is rotatably arranged on the first extrusion block 105a, so that the protective vertical rod 106c can rotate and erect. The erecting gear 106b meshes with the erecting rack 104e, so that the erecting gear 106b can rotate. A plurality of protective vertical rods 106c are arranged. The protective vertical rods 106c are received in the receiving groove 104b to reduce the occupied space of the device. After the protective vertical rods 106c are removed and erected, they protect the boarding staff. The protective cross rod 106d is connected to a plurality of protective vertical rods 106c to form a protective frame, increasing the safety of the device.

[0050] The erecting part 106 further includes a card slot 106e arranged on the erecting rotating shaft 106a, and a card plate 106f arranged on the first extrusion block 105a and adapted to the card slot 106e.

[0051] Preferably, the card slot 106e is an L-shaped slot. Through the limit of the card plate 106f, the erecting rotating shaft 106a can only rotate 90 degrees and can only rotate clockwise, preventing the protective vertical rod 106c from rotating counterclockwise and ensuring the normal use of the device.

[0052] The power part 107 includes a power telescopic rod 107a arranged on the telescopic groove 103b, and a connecting strip 107b arranged on the power telescopic rod 107a and connected to the receiving plate 104a.

[0053] Preferably, the power telescopic rod 107a provides power for the movement of the storage board 104a. At least two power telescopic rods 107a are provided to increase the stability when adding the storage board 104a and ensure sufficient power. The connecting bar 107b is used to connect the storage boards 104a on both sides, so that the power telescopic rod 107a can drive the storage boards 104a on both sides to move simultaneously.

[0054] The remaining structures are the same as those in Embodiment 1.

[0055] During the use process, the power telescopic rod 107a is started to drive the connecting bar 107b to make the storage board 104a move along the side groove 103a. The storage board 104a drives the storage groove 104b to move. Due to the limitation of the limiting groove 103c on the limiting slider 105d, the storage groove 104b moves to squeeze the first inclined surface 105e to make the first pressing block 105a move. The first pressing block 105a drives the vertical rotating shaft 106a to make the protection vertical rod 106c move. The protection vertical rod 106c drives the protection cross bar 106d to move, so that the protection cross bar 106d extends and unfolds. When the vertical gear 106b moves to mesh with the vertical rack bar 104e, the vertical gear 106b moves and rotates. The vertical gear 106b drives the vertical rotating shaft 106a to rotate. The vertical rotating shaft 106a drives the protection vertical rod 106c to make the protection cross bar 106d vertical to protect the staff.

[0056] Embodiment 3

[0057] Refer to Figures 8 to 9 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the guiding part 201 includes a guiding plate 201a arranged on the boarding plate 102b and an L-shaped guiding groove 201b arranged on the guiding plate 201a.

[0058] Preferably, the guiding plate 201a is fixedly arranged on both sides of the bottom of the boarding plate 102b to increase the stability of connection with the compensation part 202. The L-shaped guiding groove 201b is used to drive the compensation rotating rod 202d to move to ensure the normal operation of the device. The corner of the L-shaped guiding groove 201b is chamfered to avoid jamming.

[0059] The compensation part 202 includes a compensation mounting plate 202a arranged on the storage board 104a, a compensation rotating shaft 202b arranged on the compensation mounting plate 202a, a compensation rotating rod 202c arranged on the compensation mounting plate 202a, a compensation rotating rod 202d arranged on the compensation rotating rod 202c and adapted to the L-shaped guiding groove 201b, and a compensation step ladder 202e arranged on the compensation rotating shaft 202b.

[0060] Preferably, the compensation mounting plate 202a is fixedly arranged on the storage plate 104a, and the compensation mounting plate 202a is slidably arranged in the removal groove 103d so that the compensation mounting plate 202a can slide out normally. The compensation rotating shaft 202b is used for mounting the compensation step ladder 202e, and the rotating shaft of the compensation rotating rod 202c is fixedly connected to the end of the compensation rotating shaft 202b, so that the rotation of the compensation rotating rod 202c can drive the rotation of the compensation rotating shaft 202b. The length of the compensation rotating rod 202c is the same as the vertical depth of the L-shaped guiding groove 201b. When the compensation rotating rod 202d rotates into the horizontal groove of the L-shaped guiding groove 201b, the compensation rotating rod 202c just rotates 90 degrees, thus ensuring the normal operation of the device.

[0061] The remaining structures are the same as those in Embodiment 2.

[0062] During the use process, while the power telescopic rod 107a drives the storage plate 104a to deploy the protection cross bar 106d, the storage plate 104a drives the compensation mounting plate 202a to move along the removal groove 103d, and the compensation mounting plate 202a drives the compensation rotating rod 202c to move the compensation rotating rod 202d. Due to the setting of the L-shaped guiding groove 201b, when the compensation rotating rod 202d moves along the L-shaped guiding groove 201b, the compensation rotating rod 202d drives the compensation rotating rod 202c to rotate the compensation rotating shaft 202b, and the compensation rotating shaft 202b drives the compensation step ladder 202e to rotate, thereby compensating for the height of the fence on the wind power tower.
