Abstract
A kind of gas communication equipment of the echoless chamber for water craft, contain be arranged on echoless chamber side surface and with the column through hole of echoless chamber exterior, in described column through hole, axle helicallobe is being set, and the additional block cover plate that is arranged on the input end of column through hole, the sidepiece of described cover plate is connected via transfer roller with the input end of column through hole.Such structure avoided existing structure cannot avoid preventing external acoustic waves from entering echoless chamber and the sound intensity in uncontrollable echoless chamber lower than the defect of critical value.
Description
Technical field
The utility model belongs to platform device technique field, is specifically related to a kind of gas communication equipment of the echoless chamber for water craft.
Background technology
The current echoless chamber in the face of water craft, owing to need to controlling the sound intensity in echoless chamber lower than critical value, therefore echoless chamber is exactly a bounded system, yet this type of bounded system is impossible by making the unobstructed of echoless chamber and atmosphere, and the gas communication equipment of the echoless chamber of existing water craft is exactly via vane sheet is set in through hole, this kind of form can not prevent that external acoustic waves from entering echoless chamber and the sound intensity in uncontrollable echoless chamber lower than critical value.
Summary of the invention
The purpose of this utility model provides a kind of gas communication equipment of the echoless chamber for water craft, contain be arranged on echoless chamber side surface and with the column through hole of echoless chamber exterior, in described column through hole, axle helicallobe is being set, and the additional block cover plate that is arranged on the input end of column through hole, the sidepiece of described cover plate is connected via transfer roller with the input end of column through hole.Such structure avoided existing structure cannot avoid preventing external acoustic waves from entering echoless chamber and the sound intensity in uncontrollable echoless chamber lower than the defect of critical value.
In order to overcome deficiency of the prior art, the utility model provides a kind of solution of gas communication equipment of the echoless chamber for water craft, specific as follows:
A kind of gas communication equipment of the echoless chamber for water craft, contain be arranged on echoless chamber side surface 1 and with the column through hole 2 of echoless chamber exterior, the interior axle helicallobe 3 that arranging of described column through hole 2, and the additional block cover plate 4 that is arranged on the input end 5 of column through hole 2, the sidepiece of described cover plate 4 is connected via transfer roller 6 with the input end 5 of column through hole 2.
Described cover plate 4 edges spiral insulation material layer 7 are being set.
Described insulation material layer 7 is connected via pin member with cover plate 4.
Application the utility model such scheme, via be arranged on echoless chamber side surface 1 and with the column through hole 2 of echoless chamber exterior, the interior axle helicallobe 3 that arranging of described column through hole 2, and the additional block cover plate 4 that is arranged on the input end 5 of column through hole 2, the sidepiece of described cover plate 4 is connected via transfer roller 6 with the input end 5 of column through hole 2.Thus in column through hole 2 have axle helicallobe 3 to start time realize and ventilating after, synchronously via transfer roller 6, cover plate 4 is removed, the input end 5 of column through hole 2 can exchange outward with echoless chamber, continues sealing under other conditions.
Accompanying drawing explanation
Figure l is structural representation of the present utility model.
Fig. 2 is the structural representation of cover plate of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, utility model content is described further:
Shown in seeing figures.1.and.2, gas communication equipment for the echoless chamber of water craft, contain be arranged on echoless chamber side surface 1 and with the column through hole 2 of echoless chamber exterior, the interior axle helicallobe 3 that arranging of described column through hole 2, and the additional block cover plate 4 that is arranged on the input end 5 of column through hole 2, the sidepiece of described cover plate 4 is connected via transfer roller 6 with the input end 5 of column through hole 2.Described cover plate 4 edges spiral insulation material layer 7 are being set, and have strengthened like this soundproof effect.Described insulation material layer 7 is connected via pin member with cover plate 4, like this convenient disassembly.
Application the utility model such scheme, its principle of work for via be arranged on echoless chamber side surface 1 and with the column through hole 2 of echoless chamber exterior, the interior axle helicallobe 3 that arranging of described column through hole 2, and the additional block cover plate 4 that is arranged on the input end 5 of column through hole 2, the sidepiece of described cover plate 4 is connected via transfer roller 6 with the input end 5 of column through hole 2.Thus in column through hole 2 have axle helicallobe 3 to start time realize and ventilating after, synchronously via transfer roller 6, cover plate 4 is removed, the input end 5 of column through hole 2 can exchange outward with echoless chamber, continues sealing under other conditions.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, according to technical spirit of the present utility model, within spirit of the present utility model and principle, the any simple modification that above embodiment is done, be equal to replacement and improvement etc., within all still belonging to the protection domain of technical solutions of the utility model.
