Description
Technical Field
The utility model relates to an equipment specifically is a demountable assembly's shielding electromagnetic wave control box.
Background
The control box mainly assembles switchgear, measuring instruments, auxiliary equipment and the like in a closed or semi-closed cabinet body, so that the operation and safety of the control equipment are facilitated. However, many auxiliary devices and instruments in the control box are affected by electromagnetic waves, which causes a series of problems such as operation failure, especially the marine control box is more frequently contacted with electromagnetic waves such as radar signals.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model provides a demountable assembly's shielding electromagnetic wave control box.
The utility model discloses a realize through following technical scheme:
the utility model provides a but removable assecmbly's shielding electromagnetic wave control box, includes control box frame and control box inside casing, control box frame surface scribbles electrically conductive lacquer, the control box frame with the equidistance rigid coupling has 3 installing supports on every diagonal between the control box inside casing, is close to two of control box frame the copper framework is equipped with between the installing support, is close to two of control box inside casing the ferromagnetic plate framework is equipped with between the installing support.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an installation fixed bolster has both made things convenient for the installation of shield, can decide what shield to use according to service environment again, the utility model provides a copper framework for shielding high frequency signal, ferromagnetic plate frame are used for shielding low frequency signal, have guaranteed that the instrument and equipment in the control box is not influenced by the electromagnetic wave, normal operating.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view of the present invention.
In the drawings: 1. a control box outer frame; 2. a control box inner frame; 3. mounting a bracket; 4. a copper plate frame body; 5. a ferromagnetic plate frame; 6. and (3) conductive paint.
Detailed Description
The detachable assembled electromagnetic wave shielding control box comprises a control box outer frame 1 and a control box inner frame 2, wherein conductive paint 6 is coated on the outer surface of the control box outer frame 1, 3 mounting brackets 3 are fixedly connected between the control box outer frame 1 and the control box inner frame 2 at equal intervals on each diagonal line, a copper plate frame body 4 is arranged between the two mounting brackets 3 close to the control box outer frame 1, and a ferromagnetic plate frame body 5 is arranged between the two mounting brackets 3 close to the control box inner frame 2.
The control box is divided into a control box inner frame 2 and a control box outer frame 1, the surface of the control box outer frame 1 is sprayed with conductive paint 6, the conductive paint 6 has the advantages of shielding electromagnetic waves and simple operation, partial electromagnetic waves are filtered, 4 diagonals between the control box outer frame 1 and the control box inner frame 2 are fixedly connected with 3 fixed supports 3 at equal intervals, two empty slots are arranged between the 3 fixed supports 3 for inserting shielding layers, and the shielding layers can be selected to be inserted according to different applicable environments, the utility model is used for the marine control box, the marine control box is mostly influenced by the radar electromagnetic waves, the outer shielding layer is selected to be a copper plate frame body 4 to be inserted into the control box, because the resistivity of copper is low, high-frequency electromagnetic waves can generate vortex in the copper plate frame body to form the counteraction effect on the electromagnetic waves, the shielding effect is achieved, the inner shielding layer is selected to be a ferromagnetic plate frame body 5, can shield electromagnetic wave, so that the control box can achieve the effect of shielding the electromagnetic wave and avoid the influence of the electromagnetic wave on the operation of internal device equipment
In summary, the present invention is only a preferred embodiment, and should not be limited by the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
