Abstract
The present invention relates to a kind of screened rooms peculiar to vessel.The screened room peculiar to vessel that specifically electronic equipment on ship is electromagnetically shielded.It includes shell, has electromagnetic shield door on the side wall of shell.Its main feature is that having radio frequency ground stud, power-supply filter, ground connection filter, electromagnetic isolation attenuator and distribution box in the shell, the radio frequency ground stud, power-supply filter, ground connection filter and electromagnetic isolation attenuator are connected by conducting wire with distribution box.It can guarantee that the electronic equipment in it is not interfered by external electromagnetic wave using the screened room, the health of crewman will not be endangered because of electromagnetic leakage.
Description
Technical field
The present invention relates to a kind of marine vehicle components, the screen peculiar to vessel being specifically electromagnetically shielded to the electronic equipment on ship
Cover room.
Background technology
It is both known about in shipbuilding industry, in order to prevent the electromagnetic leakage of electronic equipment on ship, interference and generation
Electromagnetic wave damages staff, and electronic equipment is usually mounted in dedicated screened room on ship.
Currently, the screened room used on ship be by installed on common cabin electromagnetic shield door or electromagnetic shielding window come
Realize electromagnetic shielding.But the Ship Structure of ship is usually more complex, and the ancillary equipment used in ship's space（As illumination is set
It is standby）Connection is needed to need that ventilation equipment are installed on the cable in cabin, the bulkhead in cabin, these can all reduce entire cabin
Leakproofness so that extraneous electromagnetic wave enters in cabin the normal operation for influencing electronic equipment, and ancillary equipment cable
The indoor electronic equipment in electromagnetic wave influence cabin can be sent out.Meanwhile the certain high-power electronic devices installed in cabin（As ocean is surveyed
Control etc.）The a large amount of electromagnetic waves generated can let out from cabin, endanger the health of crewman.
Invention content
The problem to be solved in the present invention is to provide a kind of screened room peculiar to vessel, can guarantee that the electronics in it is set using the screened room
It is standby not interfered by external electromagnetic wave, the health of crewman will not be endangered because of electromagnetic leakage.
To solve the above problems, providing following technical scheme：
The screened room peculiar to vessel of the present invention includes shell, has electromagnetic shield door on the side wall of shell.Its main feature is that the shell
Inside there are radio frequency ground stud, power-supply filter, ground connection filter, electromagnetic isolation attenuator and distribution box, the radio frequency ground stud, electricity
Source filter, ground connection filter and electromagnetic isolation attenuator are connected by conducting wire with distribution box.
Wherein, the housing bottom has the ground roof beam structure on the fragmented deck of shell, and electrical insulation board is arranged at the bottom of ground roof beam structure.
Wherein, there is vent window in the housing sidewall, which is Ventiliation window.
Further improvement of these options scheme is that have aerofoil fan on the vent window.The advantages of improving in this way is profit
Indoor hot wind can be discharged with aerofoil fan, meet the needs of electronic equipment dissipating heat, is further ensured that the normal of electronic equipment
Operation.
Above scheme is taken, is had the following advantages：
Due to having radio frequency ground stud, power-supply filter, ground connection filter, electromagnetism in the shell of the screened room peculiar to vessel of the present invention
Attenuator and distribution box is isolated, radio frequency ground stud, power-supply filter, ground connection filter and electromagnetic isolation attenuator pass through conducting wire
It is connected with distribution box.Wherein, radio frequency ground stud plays the role of ground wire, and power-supply filter is used for handling feed cable interference,
Ground connection filter is used for handling electrostatic induced current interference, and electromagnetic isolation attenuator is used for handling signal cable interference.Therefore, the shielding
Room can both be handled entering indoor electromagnetic wave, can also be sent out with cable the electronic equipment and ancillary equipment of indoor location
The electromagnetic wave gone out is handled so that the indoor electronic equipment of the shielding will not be used by extraneous electromagnetic wave and other ancillary equipments
The electromagnetic wave that cable is sent out is influenced.Meanwhile the certain high-power electronic devices installed in cabin（Such as ocean observing and controlling）It generates
A large amount of electromagnetic waves will not go out from screened room internal leakage, to will not be caused to the health of crewman because of electromagnetic leakage
Harm.
Description of the drawings
Fig. 1 is the structural schematic diagram of the screened room peculiar to vessel of the present invention；
Fig. 2 is the portions the I cutaway view Amplified image of Fig. 1.
Specific implementation mode
Below in conjunction with attached drawing, present invention is further described in detail.
Shown in Fig. 1 and Fig. 2, screened room peculiar to vessel of the invention includes shell 1, and electromagnetic shielding is provided on the side wall of shell 1
Door 7 and vent window 4, the vent window 4 are Ventiliation window 4, have aerofoil fan on vent window 4.It is provided in the shell 1
Radio frequency ground stud 2, power-supply filter 3, ground connection filter 5, electromagnetic isolation attenuator 6 and distribution box 10, the radio frequency ground stud
2, power-supply filter 3, ground connection filter 5 and electromagnetic isolation attenuator 6 are connected by conducting wire with distribution box 10.The shell 1
Bottom is provided with the ground roof beam structure 8 on 1 fragmented deck of shell, and the bottom of ground roof beam structure 8 is provided with electrical insulation board 9.
In use, the screened room peculiar to vessel of the present invention is installed to the corresponding position in ship, then by ship electronic equipment
It is installed in shell 1.Play the role of ground wire using radio frequency ground stud 2, power-supply filter 3 handles feed cable interference, connects
Ground filter 5 handles electrostatic induced current interference, and electromagnetic isolation attenuator 6 handles signal cable interference, electromagnetic shield door 7 and cut-off wave
Conducting air regulator 4 is electromagnetically shielded, and to both can guarantee the normal operation of shell inner electronic equipment, ensures that the body of crewman
Health is not endangered by electromagnetic wave.
