Problems solved by technology

However, due to the different directions of the sea waves, most of the ship-borne stabilization platforms cannot achieve horizontal stability of the platform, which cannot guarantee the smooth take-off or landing of the UAV.

Embodiment 1

[0024] see figure 1 , a catamaran stabilized platform provided by the present invention includes a stable platform 2, a propeller 3, a suspension mechanism 4 and two hulls 1 that are free to pitch respectively, and the suspension mechanism 4 is connected to the hull 1 and the stable platform 2, the propeller 3 provides power for the hull 1.

[0025] Specifically, the suspension mechanism 4 includes an attitude adjustment mechanism 5 installed at the bow of the hull 1 and a shock absorbing mechanism 6 installed at the tail of the hull 1 . When the hull 1 is sailing at sea, the impact of the waves on the bow and tail of the hull 1 is inconsistent, causing the hull 1 to swing irregularly on the sea surface. The attitude adjustment mechanism 5 and the shock absorbing mechanism 6 are respectively installed on the bow and tail of the hull. The vibration transmitted from the hull 1 to the stable platform 2 is separately slowed down respectively.

[0026] Specifically, the attitude ...

Embodiment 2

[0029] see Figures 2 to 5 The difference between this embodiment and Embodiment 1 is that the linear motor 17 includes a first linear motor 12 and a second linear motor 13, the first linear motor 12 is perpendicular to the stable platform 2, and the second Two linear motors 13 are inclined to the stable platform 2 . When the hull 1 swings upwards at a certain angle to the horizontal direction under the action of waves, the first linear motor 12 remains perpendicular to the stable platform 2 and shortens its own length, and the second linear motor 13 also shortens its own length accordingly. The length is long enough to absorb the large pitch and roll vibrations of the hull 1 at medium and low frequencies, so as to achieve the purpose of shock absorption and control platform stability. In some specific embodiments, the linear motor 17 can also be set to three or more, and the linear motor 17 can also be set to be non-perpendicularly connected with the stable platform 2, all s...

Abstract

The invention provides a platform with stability enhanced by using a catamaran. The platform comprises two hulls which respectively make free pitching, a stabilized platform body, a propeller and a suspension mechanism, wherein the suspension mechanism is connected with the hulls and the stabilized platform body; the propeller is used for providing power for the hulls. The platform on which an unmanned aerial vehicle can take off and land is provided for the unmanned aerial vehicle, and the influence caused by ship shaking when the unmanned aerial vehicle takes off and lands can be effectively reduced. The two hulls which respectively make free pitching can effectively buffer the shake caused by the impact of sea waves, and the fluctuation to the stabilized platform body transmitted from the hulls is further weakened by the suspension mechanism.

Description

technical field [0001] The invention relates to the technical field of offshore ship-borne stable platforms, in particular to a platform that adopts a catamaran to increase stability. Background technique [0002] UAVs have the advantages of wide search and rescue range and fast speed, but at the same time, they also have disadvantages such as limited battery life and small carrying load. Ships are similar. They have the advantages of large load, long continuous operation time and relatively little impact from environmental factors, but have the disadvantage of slow search and rescue speed. Therefore, the combination of the two can maximize the operating efficiency. However, due to the different directions of sea waves, most of the ship-borne stabilization platforms cannot achieve horizontal stability of the platform, thus cannot guarantee the smooth take-off or landing of the UAV. Therefore, there is a need for an offshore platform suitable for the smooth take-off and lan...
