[0032] Among them; a spring 19 is installed between the upper connecting block 3 and the first limiting block 9, and the spring 19 is movably sleeved on the outer wall of the first guiding post 8, so as to use the elastic force of the spring 19 to push the foot plate 2 to show a closing trend and prevent the foot plate 2 from being easily unfolded.

The positioning groove 1706 is opened on the inner wall of the storage groove 1705. The positioning fork 1701 is clamped with the positioning block 1704 through the positioning tooth 1702 and the positioning groove 1706 to facilitate avoiding the easy sliding of the positioning fork 1701 by using the clamping between the positioning tooth 1702 and the positioning groove 1706, thereby indirectly realizing the positioning of the foot plate 2.

[0037] Among them, one side of the rack 14 is meshed with the outer wall of the gear 6 to facilitate realizing the linkage of the foot plate 2 by using the meshing transmission between the rack 14 and the gear 6.

[0038] Among them, the dust-proof mechanism 18 includes a storage rack 1803, side grooves 1804, and limit grooves 1805. The storage rack 1803 is fixedly connected to the outer wall of the fixed bar 1. The side grooves 1804 are recessed on both sides of the storage rack 1803. The limit grooves 1805 are arranged between the storage rack 1803 and the fixed bar 1 to facilitate providing a channel for the dust-proof cloth 1808 to unfold.

[0039] Among them, the dust-proof mechanism 18 further includes a bottom plate 1801 and mounting holes 1802. The bottom plate 1801 is fixedly connected to the outer wall of the storage rack 1803.

One end of the pull rope 1810 is fixedly connected to the side of the first support piece 1807 away from the dust-proof cloth 1808, and the other end of the pull rope 1810 is fixedly connected to the side of the second support piece 1809 away from the dust-proof cloth 1808. By providing the fixing strip 1, the support bottom frame 12 and the dust-proof mechanism 18, the dust can be prevented by covering with the dust-proof cloth 1808 after the device is stored, improving the cleanliness of the device.

[0041] Working principle: When in use, the device is installed on the surface of the hull. When repairing the sensor, the foot plate 2 is rotated downward through the holding port 20 to unfold the foot plate 2. When the foot plate 2 unfolds, it will drive the mounting block 5 and the gear 6 to rotate on the surface of the support shaft 7. When the gear 6 rotates, it will drive the rack 14 to slide. When the rack 14 slides, it will drive the slider 15 to slide synchronously on the surface of the support block 13, thereby driving other racks 14 to move, and indirectly driving other gears 6 to rotate by the synchronous movement of multiple racks 14, and the gear 6 drives other foot plates 2 to rotate and unfold synchronously. At the same time, when the slider 15 slides, it will drive the positioning fork 1701 to move synchronously. The positioning fork 1701 will be driven to slide inside the storage groove 1705, and the positioning between the positioning tooth 1702 and the positioning groove 1706 will position between the positioning fork 1701 and the positioning block 1704, thereby assisting the staff to climb. When the device is not in use, pull the end of the pull rope 1810 close to the sliding block 1806, thereby driving the sliding block 1806 to slide along the side groove 1804. When the sliding block 1806 slides, it will drive the first support piece 1807 to slide synchronously, so that the first support piece 1807 slides from the upper connecting block 3 to the lower connecting block 4, thereby driving the dust-proof cloth 1808 to cover the device. At the same time, when the dust-proof cloth 1808 slides, it will drive the second support piece 1809 on the other side to slide from the lower connecting block 4 to the upper connecting block 3, thereby driving the other end of the pull rope 1810 to be received by the limit groove 1805.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
