All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
Referring to fig. 1-4, there is shown an offshore highway buoyancy compensating device for keeping a deck stable according to a preferred embodiment, comprising a deck 1, connecting rods 2, buoyancy blocks 3 and air bags 4;
A plurality of connecting rods 2 are fixed on the lower surface of the bridge deck 1; the middle part of each connecting rod 2 is provided with one buoyancy block 3, and the lower part of each connecting rod 2 is provided with one air bag 4;
buoyancy piece 3 with be equipped with slide mechanism between connecting rod 2, gasbag 4 with the mutual contact of connecting rod 2 is opened on the surface has a plurality of air vents 41, the inside cavity of connecting rod 2 forms sealed cavity 6, gasbag 4 with cavity 6 is linked together, buoyancy piece 3 follows along can change when connecting rod 2 reciprocates the volume of cavity 6.
In a preferred embodiment, the sliding mechanism includes two fixing rods, which are a first fixing rod 31 and a second fixing rod 32, respectively, the buoyancy block 3 is connected to the first fixing rod 31 and the second fixing rod 32, a sliding slot 7 is formed in a connecting portion between the first fixing rod 31 and the second fixing rod 32 and the connecting rod 2, and the first fixing rod 31 and the second fixing rod 32 both slide up and down along the corresponding sliding slot 7.
The sliding mechanism has the function that the buoyancy block 3 can move up and down along with the fluctuation of sea surface waves, so that the air pressure of the cavity 6 in the connecting rod 2 is changed, and the air inflation and air deflation of the air bag 4 are realized.
The sliding mechanism has various structural forms, and the embodiment exemplifies a structure having the first fixing lever 31 and the second fixing lever 32 sliding in the slide groove 7 of the connecting rod 2, which is simple and has a fast response speed.
