The invention discloses a three-dimensional frame type buoyant raft vibration isolation device. The three-dimensional frame type buoyant raft vibration isolation device comprises a frame type main beam structure. According to the three-dimensional frame type buoyant raft vibration isolation device, a secondary beam is installed inside each frame in an inclined mode, the main beam structure comprises a first main beam part and a second main beam part which are connected into a whole, the first main beam part and the second main beam part are both of inverted-trapezoid structures, the first main beam part is higher than the second main beam part, a first horizontal type water pump, a second horizontal type water pump, a third horizontal type water pump, a vertical type water pump, a first reduction gearbox and a second reduction gearbox are installed in a frame structure formed by the first main beam part and the second main beam part, the top of the first main beam part and the top of the second main beam part are respectively provided with a first acoustic shield, second acoustic shields are installed on the periphery of the main beam structure, and a muffler and ventilation device is further installed on the top of each first acoustic shield, the whole structure is installed inside a shell body, bases are installed on the inner wall surfaces of the shell body, and two sides of the main beam structure are installed on the bases through vibration isolators. The three-dimensional frame type buoyant raft vibration isolation device has the advantages of being good in vibration isolation effect.
Description
technical field [0001] The invention relates to a vibration isolation device, in particular to a three-dimensional frame type floating raft vibration isolation device, which is used for vibration isolation control in ship equipment control and other similar fields. Background technique [0002] Vibration isolation measures are usually used in the vibration control of ship equipment, which can be divided into single-layer vibration isolation, double-layer vibration isolation and floating raft vibration isolation according to their types. Single-layer vibration isolation is the simplest means of vibration isolation. Connecting vibration equipment to the structure through a vibration isolator is single-layer vibration isolation. Double-layer vibration isolation is developed on the basis of single-layer vibration isolation. The vibration equipment is connected to the intermediate mass through the vibration isolator, and then the intermediate mass is connected to the structure th...
