[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] like Figure 1 - Figure 4 The illustrated isolated and anti-interference backup power output protection device includes a backup power box 10 and a backup power supply 30. A cavity 11 is provided in the backup power box 10, and an electromagnetic shielding layer is provided on the inner wall of the cavity 11. Specifically, a bracket is further provided in the cavity 11, and the bracket includes a plurality of fixed beams 24 and a supporting member 21. The plurality of fixed beams 24 are respectively provided on both sides of the cavity 11 and spaced apart, and the fixed beams 24 on both sides of the cavity 11 are provided correspondingly.

[0027] In addition, the supporting member 21 is connected between the corresponding fixed beams 24 on both sides of the cavity 11, and the supporting member 21 includes a plurality of supporting pieces 211 and a plurality of connecting seats 22, and the ends of each supporting piece 211 are connected to the fixed beams 24, that is, a plurality of supporting pieces 211 are connected between the fixed beams 24 corresponding to the two side walls of the cavity 11, and the plurality of supporting pieces 211 of the same supporting member 21 are arranged at intervals in the width direction of the cavity 11. The connecting seats 22 are installed on the plurality of supporting pieces 211 and slide along the length direction of the cavity 11, and a plurality of connecting holes 221 are provided on the connecting seats 22.

[0028] On the basis of the above structure, the isolated and anti-interference backup power output protection device of the utility model can be used to install the backup power supply 30 on the connection seat 22 of the supporting member 21. During assembly, the shell of the backup power supply 30 can be assembled into the connection hole 221 of the connection seat 22 by means of screws or bolts. Since the connection seat 22 can slide relative to the multiple supporting pieces 211 of the supporting member 21, the position of the connection seat 22 can be adjusted, so that the backup power supply 30 assembled on the bracket can be moved to different positions for wiring and installation, which is more convenient to use.

[0029] In addition, the bracket has multiple groups of fixed beams 24 distributed at intervals in the height direction of the side wall of the cavity 11, so that the bracket has multiple supporting members 21 distributed in the height direction of the cavity 11, which can divide the cavity 11 into supporting compartments with different height directions. The connecting seats 22 of the supporting members 21 at different heights can be connected to the backup power supply 30, and can be assembled and connected according to different usage requirements.

[0030] It should also be noted that the supporting member 21 has a plurality of supporting pieces 211, which can support the backup power supply 30 on the connecting seat 22 in the width direction, and the structure is stable after the backup power supply 30 is assembled. Of course, the inner wall of the cavity 11 of the backup power box 10 is provided with an electromagnetic shielding layer, which can effectively shield electromagnetics and isolate electromagnetic interference, making the use process safer.

[0031] Furthermore, a sliding block 222 may be provided at the bottom end of the connection seat 22, and a sliding groove 212 may be formed between two adjacent supporting pieces 211, so that the sliding block 222 of the connection seat 22 may be slidably connected to the sliding groove 212, and the sliding groove 212 may guide the sliding of the connection seat 22 to prevent the connection seat 22 from swinging during the sliding movement, and the structure is stable. During sliding, since the sliding groove 212 is formed by two adjacent supporting pieces 211, there is no need to process the sliding groove 212 separately. It is only necessary to connect the ends of the supporting pieces 211 to the fixed beam 24 by screws and distribute them at intervals.

[0032] Of course, other electrical components such as isolation transformers, insulation detectors, alarm devices, etc. in the prior art can also be set in the above-mentioned backup power box cavity, and can be rotated and assembled according to the actual use of the backup power box.

[0034] Specifically, the backup power supply 30 is connected to the connection seat 22 of the uppermost support member 21 of the bracket, and the connection seat of the lowermost support member 21 of the bracket can be equipped with electrical components such as a circuit breaker 40 and a relay 50 to protect the power supply during the use of the backup power supply 30. Of course, the backup power supply 30 can be a UPS power supply or a storage battery in the prior art, and the relay 50 and the circuit breaker 40 can be both of the prior art, and they can be assembled on the connection seat 22 of the bracket.

[0035] Specifically, in order to facilitate the electrical connection between the backup power supply 30 and the relay 50, the circuit breaker 40, etc., a plurality of wiring sheets can be provided on the bracket, and the wiring sheets are provided with a wiring cavity. One end of the wiring sheet extends to the bottom end of the bracket, and the other end of the wiring sheet extends to the top end of the bracket.

[0036] Furthermore, a plurality of wire holes 213 may be provided on the supporting sheet 211.

[0040] Of course, the box door 14 can be rotatably assembled to the power backup box 10 by means of hinges or other structures in the prior art, and a locking structure can be provided on the box door and the power backup box, so that the box door can be locked by the locking structure when it is closed.

[0041] Furthermore, the electromagnetic shielding layer is formed by a conductive paint layer coated on the inner wall of the cavity 11. The conductive paint is a prior art. Its composite particles containing copper, silver, etc. are conductive particles and have excellent conductive properties. The conductive paint can be sprayed and brushed to make the completely insulating non-metallic or non-conductive surface have the same properties of absorbing, conducting and attenuating electromagnetic waves as metals. Therefore, it can effectively shield electromagnetic wave interference.

[0042] Of course, the electromagnetic shielding layer may also be made of conductive cloth, conductive foam or conductive adhesive and other materials in the prior art. In short, electromagnetic shielding and anti-interference can be achieved.
