Abstract
The utility model relates to a marine screened room. Specifically say so and carry out electromagnetic shield's marine screened room to the electronic equipment on the boats and ships. It includes the casing, has the electromagnetic shield door on the lateral wall of casing. Its characteristics are there are the stake of radio frequency ground connection, power filter, ground connection wave filter, electromagnetic isolation attenuator and block terminal in the casing, the stake of radio frequency ground connection, power filter, ground connection wave filter and electromagnetic isolation attenuator all link to each other with the block terminal through the wire. Use this screened room can guarantee that the electronic equipment in it is not disturbed by external electromagnetic, can not leak the healthy of harm crewman because of the electromagnetism.
Description
Technical field
The utility model relates to a kind of marine vehicle component, is the shielded enclosure peculiar to vessel electronic equipment on boats and ships being carried out to electromagnetic shielding specifically.
Background technology
All know in shipbuilding industry, in order to prevent the electromagnetic leakage of electronic equipment on boats and ships, the electromagnetic wave of interference and generation damages staff, and on boats and ships, electronic equipment is normally installed in special shielded enclosure.
At present, shielded enclosure boats and ships used by installing electromagnetic shield door or electromagnetic shielding window realizes electromagnetic shielding on common cabin.But the Ship Structure of boats and ships is usually more complicated, and the auxiliary equipment used in ship's space (as lighting apparatus) needs to connect the cable running through cabin, the bulkhead in cabin needs ventilation equipment are installed, these all can reduce the sealing in whole cabin, make extraneous electromagnetic wave enter into the normal operation that cabin affects electronic equipment, and auxiliary equipment cable also can send the electronic equipment in electromagnetic wave influence cabin.Meanwhile, a large amount of electromagnetic waves that some high-power electronic device (as ocean observing and controlling etc.) installed in cabin produces can let out from cabin, and harm crewman's is healthy.
Utility model content
Problem to be solved in the utility model is to provide a kind of shielded enclosure peculiar to vessel, uses this shielded enclosure can ensure electronic equipment in it by the interference of external electromagnetic ripple, can not endanger the healthy of crewman because of electromagnetic leakage.
For solving the problem, provide following technical scheme:
Shielded enclosure peculiar to vessel of the present utility model comprises housing, and the sidewall of housing has electromagnetic shield door.Be characterized in having radio frequency ground stud, power-supply filter, ground connection filter, electromagnetic isolation attenuator and distribution box in described housing, described radio frequency ground stud, power-supply filter, ground connection filter are all connected with distribution box by wire with electromagnetic isolation attenuator.
Wherein, described housing bottom has the ground roof beam structure on fragmented for housing deck, and electrical insulation board is arranged at the bottom of ground roof beam structure.
Wherein, described housing sidewall has ventilating window, this ventilating window is Ventiliation window.
Further improvement of these options scheme is that described ventilating window has aerofoil fan.The advantage of such improvement utilizes aerofoil fan the hot blast of indoor can be discharged, and meets the demand of electronic equipment dissipating heat, ensures the normal operation of electronic equipment further.
Take above scheme, have the following advantages:
Have radio frequency ground stud, power-supply filter, ground connection filter, electromagnetic isolation attenuator and distribution box in housing due to shielded enclosure peculiar to vessel of the present utility model, radio frequency ground stud, power-supply filter, ground connection filter are all connected with distribution box by wire with electromagnetic isolation attenuator.Wherein, radio frequency ground stud plays the effect of earth connection, power-supply filter be used for process feed cable interference, ground connection filter be used for process electrostatic induced current interference, electromagnetic isolation attenuator be used for processing signals cable interference.Therefore, this shielded enclosure both can process entering into indoor electromagnetic wave, also can the electromagnetic wave that the electronic equipment of indoor location and auxiliary equipment cable send be processed, the electromagnetic wave that the electronic equipment in this shielded enclosure can not be sent by the electromagnetic wave in the external world and other auxiliary equipment cables affect.Meanwhile, a large amount of electromagnetic waves that some high-power electronic device (as ocean observing and controlling etc.) installed in cabin produces also can not be gone out from shielded enclosure internal leakage, thus can not work the mischief to the healthy of crewman because of electromagnetic leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of shielded enclosure peculiar to vessel of the present utility model;
Fig. 2 is the I portion cutaway view Amplified image of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, shielded enclosure peculiar to vessel of the present utility model comprises housing 1, the sidewall of housing 1 is provided with electromagnetic shield door 7 and ventilating window 4, and this ventilating window 4 is Ventiliation window 4, and ventilating window 4 has aerofoil fan.Be provided with radio frequency ground stud 2, power-supply filter 3, ground connection filter 5, electromagnetic isolation attenuator 6 and distribution box 10 in described housing 1, described radio frequency ground stud 2, power-supply filter 3, ground connection filter 5 are all connected with distribution box 10 by wire with electromagnetic isolation attenuator 6.Be provided with the ground roof beam structure 8 on fragmented for housing 1 deck bottom described housing 1, the bottom of ground roof beam structure 8 is provided with electrical insulation board 9.
During use, shielded enclosure peculiar to vessel of the present utility model is installed to the relevant position in boats and ships, then boats and ships electronic equipment is installed in housing 1.Radio frequency ground stud 2 is utilized to play the effect of earth connection, power-supply filter 3 processes feed cable interference, ground connection filter 5 processes electrostatic induced current interference, electromagnetic isolation attenuator 6 processing signals cable disturbs, electromagnetic shield door 7 and Ventiliation window 4 carry out electromagnetic shielding, thus both can ensure the normal operation of housing inner electronic equipment, can ensure that again crewman's is healthy not by electromagnetic harm.
