Abstract

An observation platform device, including a platform deck, an observation mechanism disposed on the platform deck, a primary swing reduction and self-righting mechanism, and a secondary swing reduction mechanism. The primary swing reduction and self-righting mechanism includes a hollow upper support rod, a solid lower support rod, a buoyant cabin, and a counter weight cabin. The lower support rod includes a lower end fixedly connected to the counter weight cabin, and an upper end fixedly connected to the buoyant cabin. The secondary swing reduction mechanism includes a water pond, a plurality of wing-type supports, and a plurality of spaced fan-shaped floating cabins. The plurality of wing-type supports each includes an upper end fixedly connected to a lower plane of the platform deck, and a lower end fixedly connected to an upper plane of the fan-shaped floating cabins.

First claim

The invention claimed is:

1. An observation platform device, comprising:
a platform deck;
an observation mechanism disposed on the platform deck;
a primary swing reduction and self-righting mechanism; and
a secondary swing reduction mechanism;

wherein
the primary swing reduction and self-righting mechanism comprises a hollow upper support rod, a solid lower support rod, a buoyant cabin separated by a plurality of watertight bulkheads, and a counter weight cabin separated by a plurality of non-watertight bulkheads;
the lower support rod comprises a lower end fixedly connected to the counter weight cabin, and an upper end fixedly connected to the buoyant cabin;
a sleeve is inserted into the buoyant cabin, and the upper support rod comprises a lower end inserted into the sleeve and fixed by a clamp;
the secondary swing reduction mechanism comprises a water pond, a plurality of wing-type supports, and a plurality of spaced fan-shaped floating cabins;
the plurality of wing-type supports each comprises an upper end fixedly connected to a lower plane of the platform deck, and a lower end fixedly connected to an upper plane of the fan-shaped floating cabins;
the upper support rod comprises an upper end fixedly connected to a center of a bottom plane of the water pond;
the plurality of fan-shaped floating cabins, the plurality of wing-type supports, the platform deck and the observation mechanism floats in water filling the water pond;
a center of buoyancy of the observation platform device is located above the center of gravity thereof; and
an anchor chain is connected to an upper lug fixed on the buoyant cabin, a lower lug fixed on the counter weight cabin, and a suction anchor disposed on a sea bottom.

2. The device of claim 1 , wherein the plurality of wing-type supports and the plurality of fan-shaped floating cabins are both five in number, and five wing-type supports are evenly distributed along angular bisectors of five evenly distributed fan-shaped floating cabins.

3. The device of claim 1 , wherein a water surface in the water pond is higher than an upper surface of the plurality of fan-shaped floating cabins, and is lower than an upper surface of the plurality of wing-type supports.

4. The device of claim 1 , wherein a support platform is fixed on the upper support rod, a plurality of branched support rods is connected to the support platform, and a bottom plane of the water pond is supported by the plurality of branched support rods.

5. The device of claim 1 , wherein a plurality of brackets is arranged at joints between the lower support rod and the buoyant cabin, and between the lower support rod and the counter weight cabin.
