Problems solved by technology

The more rapid the current, the greater the wind speed, the more severe the bumps and swings. The infinite scenery is on dangerous peaks. Scientific investigations often go to sea areas with abnormal ocean activities to engage in scientific research activities, which aggravates the shaking of the hull with the waves. In short, the existing ships Can't get rid of this bump and sway

Embodiment 1

[0020] Such as figure 1 , the platform base inner ring 104 and the platform base outer ring 107 are spherical, the platform 103 is fixed on the platform base inner ring 104 to form a detachable rigid connection, and a spherical rolling body is installed between the platform base inner ring 104 and the platform base outer ring 107 109, the rolling element cage 108 keeps the spherical rolling elements 109 at an appropriate distance to prevent the spherical rolling elements 109 from colliding with each other; on the bracket 110 under the outer ring 107 of the platform base, the bracket 110 is installed on the elastic buffer device 111, and the elastic buffer device 111 is fixed On the flat base 112 of the ship, the counterweight 114 is fixed inside the inner ring 104 of the platform base to lower the center of gravity of the platform system so that the platform 103 is in a horizontal position, and the weight of the counterweight 114 is 3 to 3% greater than the load carried on the ...

Embodiment 2

[0022] Such as figure 2 , the inner ring 202 of the platform base and the outer ring 203 of the platform base are similar ellipsoidal surfaces, so that the volume of the fluid counterweight can be increased, and the range of changing the natural frequency of the platform system is larger. The locking device 201 is inserted into the locking device hole 101 on the platform and the locking device hole 116 on the flat base, and the platform system becomes a rigid system, which is convenient for handling and storage.

Embodiment 3

[0024] Such as image 3 , the support of the platform system is divided into a concave multi-layer platform base inner ring 301, a platform base middle ring 302 and a platform base outer ring 303, forming a stable and balanced system. The layers are supported by rolling elements 306, and the inner layer cage 304 And the outer layer cage 305 keeps the rolling elements 306 evenly distributed between the layers, the rolling of the spherical rolling elements 306 reduces the shaking of the waves transmitted by the hull, and reduces the shaking of the ship caused by the waves on the platform supported by the inner layer.

[0025] Let the rolling friction resistance coefficient of the platform system with single-layer rolling elements be K, and the rolling friction resistance coefficient of the platform system with double-layer rolling elements be K*K. The rolling friction resistance of the platform system with double-layer rolling elements is obviously higher than that of the single-...

Abstract

The invention relates to a stable platform system of a light and small ship, in particular to a platform system for an inshore scientific research vessel. The platform system comprises a platform, a support, a platform base inner ring, a platform base outer ring, a rolling body, a rolling body retainer, an elastic buffering device, a flat plate base, an inner ring limiting device, an outer ring limiting device, a fluid balance weight, a fluid balance weight injection port, a balance weight, an elastic limiting device and a locking device. The spherical rolling body is installed between the platform base inner ring and the platform base outer ring, the rolling body retainer makes the spherical rolling body keep an appropriate separation distance to prevent mutual collision of the spherical rolling body. The shake of the small ship is weakened by the motion of the rolling body, and shake amplitude depends on the rolling friction resistance of the system, and the platform system is suitable for scientific research workers to have a rest and installation of high-precision deck experiment apparatuses.

Description

technical field [0001] The invention relates to a stable platform system for light and small ships, in particular to a platform system for offshore scientific investigation ships, which belongs to the technical field of marine engineering. Background technique [0002] Scientific research ships carry scientific instruments and researchers, have a small load, and have no special requirements for speed. Scientific researchers only spend less time working at sea during scientific investigations than fishermen and crews. Especially for graduate students who go to sea for the first time, it is difficult for scientific researchers to adjust their physical condition to adapt to life at sea in a short period of time. Last year, the students went to sea because of severe seasickness, and there was no rescue equipment and conditions on board, so the itinerary and route of the near-coast scientific expedition had to be shortened. Vigorous shaking may also cause equipment damage or los...
