As shown in FIG. 1 , most of the lower cabin body 5 is below the sea level 4 .

Equally, the anchor chain 8 at the bottom of the lower cabin body 5 is used for anchoring the whole platform.

[Example 2]

On the basis of Embodiment 1, the top of the upper cabin body 2 has a detection port, and the loading platform includes two longitudinal movable hinges 2-1, two elastic telescopic rods 2-2, a rotating frame 2-3, two Horizontal movable hinge 2-4 and bearing platform 2-5, two longitudinal movable hinges 2-1 are respectively connected on opposite sides of the detection port, the lower end of longitudinal movable hinge 2-1 is connected with an elastic telescopic rod 2-2, two elastic telescopic rods The lower ends of the rods 2-2 are respectively connected to the opposite sides of the rotating frame 2-3, and the other two sides of the rotating frame 2-3 are respectively connected with transverse movable hinges 2-4, and the transverse movable hinges 2-4 are respectively connected to the carrying platform 2-4 through connecting rods. 5 opposite sides.

The bottom of the carrying platform 2-5 is also provided with a drain port 2-6.

Inwardly extending suspension connecting rods are also connected to opposite sides of the detection port, and two longitudinal movable hinges 2-1 are respectively connected to the suspension connecting rods.

As shown in Fig. 2 to Fig. 4, a detection port is opened on the top of the upper cabin body 2 for the equipment on the loading platform to detect external environment information. The loading platform is connected to the side wall of the detection port.

As shown in Figure 2, the loading platform first includes two longitudinal movable hinges 2-4, and the two longitudinal movable hinges 2-4 are respectively connected to the opposite sides of the detection port, as shown in Figure 2, connected to the left and right sides, The bottom of each longitudinal movable hinge 2-4 is connected with the vertically downward elastic telescopic rod 2-2, and the lower ends of the two elastic telescopic rods 2-2 are respectively connected to the opposite sides of the rotating frame 2-3, as shown in Fig. 2 connected to the rotating frame 2 -3 on the left and right sides, the horizontal living hinge 2-4 is connected to the other two sides of the rotating frame 2-3, as shown in Figure 2, it is connected to the front and rear sides of the rotating frame 2-3, and the horizontal living hinge 2-4 is connected through the downward rigidity The rod is connected to the carrying platform 2-5, and the testing device 1 is placed on the carrying platform 2-5.

The longitudinal movable hinge 2-1 can rotate along the longitudinal direction, and is used to release the energy generated when shaking back and forth; Part of the energy, the lateral living hinge 2-4 can rotate in the lateral direction to release the energy generated when shaking from side to side.

When the platform as a whole shakes back and forth, due to the existence of the longitudinal movable hinge 2-1, the force in the front and rear direction cannot be transmitted to the elastic telescopic rod 2-2, and the elastic telescopic rod 2-2 can basically vertically move under the pulling force of the weight below. Straight, first of all, the vertical living hinge 2-1 can freely rotate back and forth, which means that it receives little resistance when it rotates. According to the action force and reaction force, when other things rotate, it is not easy to transmit force to it. That is to say, it is not strenuous. Similar to an ice surface with less friction, it is not easy for people to walk.

Therefore, when the platform as a whole shakes back and forth, according to the relative motion, the longitudinal movable hinge 2-1 is effortless, and it does not rotate, but the truss-shaped steel frame 2-7 connected to the longitudinal movable hinge 2-1 rotates , because the longitudinal living hinge 2-1 itself does not rotate back and forth, so the bar below it is straight, and the lower part of the whole device is equivalent to no front and rear displacement, so it is stable.

And when the platform as a whole rocked from side to side, although the truss-shaped steel frame 2-7 would be inclined, thereby causing the stretching or contraction of the elastic telescopic rod 2-2, and the rotating frame 2-3 would rotate, but the horizontally movable hinge 2-4 would not move substantially. Affected, the force in the left and right directions cannot be transmitted to the bearing platform 2-5, and the bearing platform 2-5 will basically remain vertical under the action of gravity. When the platform shakes left and right, assuming that the elastic rod 2-3 is rigid, Then the rotating frame 2-4 will swing around the longitudinal movable hinge 2-1 instead of rotating, and the lower part will easily produce a large displacement, but because 2-3 is an elastic rod, when shaking left and right, the elastic rod 2-3 itself It can be contracted, and the force generated when shaking left and right will act more on the rotation of the rotating frame 2-4. When the rotating frame 2-4 rotates, the force is not easily transmitted to the lateral movable hinge 2-2. Because the horizontal living hinge 2-2 can freely rotate along the left and right directions, according to the reciprocity of force action, that is, the rotating frame 2-4 can freely rotate at the contact point of the horizontal hinge 2-2.

Therefore, after the three displacement release processes of the longitudinal living hinge 2-1, the rotating frame 2-4 and the lateral living hinge 2-2, when the lower bearing platform 2-5 is relatively heavy, the bearing platform 2-5 is not easy to be front and rear. Or for the displacement in the left and right directions, the displacement mainly occurs up and down. The stability is further improved, thereby ensuring that the test equipment 1 therein has a better wind measurement condition.

The draining port 2-6 discharges the rainwater etc. falling from the detection port from the bearing platform 2-5.

The rods form a stable structure that can better bear the weight of the entire loading platform.
