Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solution of the present invention, and in order to better understand technological means of the present invention, below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Fig. 1 is marine tidal-current energy generator group cabin back segment seal structure for casing schematic diagram.
Fig. 2 is the detailed view in A portion in Fig. 1.
Fig. 3 is cabin back segment cylindrical shell and the hinged schematic diagram of hatch door.
Embodiment
The invention provides a kind of marine tidal-current energy generator group cabin seal structure for casing, its structure is simple, cheap, be convenient to safeguard, reliably effective, adopt the marine tidal-current energy generator group of this structure to have good resistance to compression, sealing effect under real sea, ensure the normal operation of unit.
Refer to shown in Fig. 1,2, marine tidal-current energy generator group cabin of the present invention seal structure for casing, adopt and form is set as follows:
Cabin housing comprises cabin cylindrical shell 1 and hatch door 2, and wherein, only show the cylindrical shell 102 of cabin back segment in Fig. 1, the front end of the cylindrical shell 102 of back segment is provided with mounting flange 101, and for being connected with cabin leading portion, hatch door 2 is connected to the rear end of cylindrical shell 102.
Hatch door 2 is set to the arc-shaped in evagination backward, and namely have dome type structure 201, this structural design is mainly for meeting underwater anti-pressure ability.No matter from the stability of structure, structure resistance to compression and production technology, dome structure effectively can meet unit to intensity, rigidity and the requirement to aspects such as the anti-pressure abilities of water.
Primary seal circle 3 is provided with between hatch door 2 and cylindrical shell 102, the rearward end of primary seal circle 3 is arranged in the annular groove 203 of setting on hatch door 2, because primary seal circle 3 and both sides compressing structure Long contact time may produce adhesion phenomenon, need when unit maintenance keeps in repair to open hatch door 2, primary seal circle 3 may be made to drop, for preventing primary seal circle 3 phenomenon that drops from occurring, be provided with protruding Drop-proof chuck in annular groove 203, namely global design becomes invaginating groove structure to block primary seal circle 3.
