Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrical cabinet, especially to a protection structure and electrical cabinet thereof. BACKGROUND

[0002] The electrical cabinet is a cabinet made of steel material to protect the normal work of components, and the manufacturing materials of the electrical cabinet are generally divided into hot-rolled steel plate and cold-rolled steel plate. The cold-rolled steel plate is softer than the hot-rolled steel plate, and is more suitable for the manufacturing of the electrical cabinet. The electrical cabinet is widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] The internal components of the electrical cabinet are very precise parts, and are prone to failure due to impact, resulting in damage. Therefore, the shell of the electrical cabinet is very strong. However, in order to ensure the normal heat dissipation of the electrical cabinet, a plurality of heat dissipation holes need to be provided. The protection performance of the heat dissipation hole position of the electrical cabinet is weak, and after being impacted or extruded by a heavy object, the heat dissipation hole position is easily deformed, causing damage to the internal components and reducing the protection performance of the electrical cabinet.

[0004] Therefore, it is necessary to provide a new protection structure and electrical cabinet thereof to solve the above technical problems. SUMMARY

[0005] In order to solve the above technical problems, the present application provides a protection structure and electrical cabinet thereof.

[0006] The protection structure provided by the present application comprises: a contraction device, the contraction device comprising a contraction installation shell, a contraction connecting block, a contraction sliding groove and a screw rod groove, the contraction connecting block being symmetrically and slidably installed inside the contraction installation shell, the contraction sliding groove being symmetrically provided on the inner wall of the contraction installation shell, and the screw rod groove being provided in the contraction connecting block; a protection mechanism, the protection mechanism comprising a protection installation groove, a protection installation plate, a rectangular groove, a rectangular sliding block and a protection baffle, the protection installation groove being provided on the top of the contraction connecting block, the protection installation plate being slidably installed inside the protection installation groove, the rectangular groove being provided on the side surface of the contraction connecting block and being communicated with the protection installation groove, the rectangular sliding block being fixedly connected to the side surface of the protection installation plate and being slidably connected to the rectangular groove, and the protection baffle being installed on the surface of the protection installation plate; and a rotating mechanism, the rotating mechanism being symmetrically installed on the side surface of the protection baffle and being fixedly connected to the surface of the protection installation plate. When the protection of the heat dissipation hole body is needed, the contraction connecting block moves out of the inside of the contraction sliding groove. In the moving-out process of the protection baffle, the protection baffle is tightly attached to the inner wall of the contraction sliding groove. The protection installation plate drives the rectangular sliding block to slide upward along the inner wall of the protection installation groove and the rectangular groove, so as to protect the heat dissipation hole body by the protection baffle. After the protection baffle is damaged by multiple impacts, the protection baffle can be replaced by the rotating mechanism.

[0007] Preferably, the shrinking device further includes a bidirectional motor and a bidirectional lead screw. The bidirectional motor is fixedly installed on the inner wall of the shrinking mounting housing, and the bidirectional lead screw is rotatably connected to the inner wall of the shrinking mounting housing. The bidirectional lead screw and the lead screw groove are meshed together. The output shaft of the bidirectional motor and the surface of the bidirectional lead screw are meshed together by bevel gears. When the bidirectional motor is started, the bevel gear on the output shaft of the bidirectional motor engages with the bevel gear on the surface of the bidirectional lead screw, driving the bidirectional lead screw to rotate. The bidirectional lead screw, in turn, moves the lead screw groove, moving the shrinking connecting block out of the shrinking slide groove to protect the heat dissipation hole body. When protection is not required, the bidirectional motor rotates in the opposite direction, and the bidirectional lead screw retracts the shrinking connecting block into the shrinking slide groove.

[0008] Preferably, the angle between the inner wall of the shrink chute and the inlet position is 60°. When the protective baffle enters or exits the inner wall of the shrink chute, the surface angle fits the angle between the inner wall of the shrink chute and the outlet position, which facilitates the quick entry and exit of the protective baffle.

[0009] Preferably, the protective mechanism further includes buffer springs. Buffer springs are symmetrically and equidistantly fixed to the inner wall of the protective mounting groove, and the buffer springs are fixedly connected to the bottom of the protective mounting plate. When the shrink connecting block moves out of the shrink slide, the buffer springs slowly open from the tightened state, causing the protective mounting plate to drive the rectangular slider to slide upwards along the protective mounting groove and the inner wall of the rectangular groove. When the shrink connecting block retracts into the shrink slide, the buffer springs slowly contract from the open state, causing the protective mounting plate to drive the rectangular slider to slide downwards along the protective mounting groove and the inner wall of the rectangular groove.

[0010] Preferably, the rotating mechanism includes a limiting seat, a first rotating seat, a rotating plate, a second rotating seat, a connecting hole, and a connecting seat. The limiting seat is fixedly connected to the side of the protective baffle. The first rotating seat and the second rotating seat are symmetrically fixedly connected to the surface of the protective mounting plate. The rotating plate is rotatably connected to the inner wall of the first rotating seat. The rotating plate has a connecting hole on its surface. The connecting seat is fixedly connected to the top of the second rotating seat, and the connecting seat and the connecting hole pass through each other. The rotating mechanism also includes a locking block and a return spring. The locking block is symmetrically slidably connected to the inner wall of the connecting seat, and the return spring is symmetrically fixedly connected to the inner wall of the connecting seat. The locking block and the return spring are fixedly connected. Next, bring the protective baffle close to the protective mounting plate, with the limit seat positioned between the first and second rotating seats. Rotate the rotating plate, bringing it close to the second rotating seat. The connecting seat passes through the connecting hole, and the locking block is pressed by the inner wall of the connecting hole, first entering the connecting seat. The return spring is compressed and contracts, and the connecting seat passes through the connecting hole. The return spring returns to its original position and opens, moving the locking block out of the connecting seat. Quickly connect the rotating plate and the connecting seat, and fix the protective baffle and the protective mounting plate together. Press the locking block to send it into the connecting seat, facilitating the separation of the rotating plate and the connecting seat. Remove the protective baffle for replacement.

[0011] Preferably, the contraction connecting block is internally symmetrically provided with a guide groove, and the guide groove is located on both sides of the lead screw groove; the contraction sliding groove is internally symmetrically fixedly connected with guide rods, and the guide groove and the guide rods are in sliding connection; when the contraction connecting block moves out of and into the contraction sliding groove, the guide rods slide in the guide groove, thereby playing a guiding and anti-deviation role; when the contraction connecting block moves into and out of the contraction sliding groove, stability is maintained, and shaking is not easily caused.

[0012] Preferably, the protection baffle is internally symmetrically provided with reinforcing grooves at equal intervals, thereby increasing the load-bearing performance and physical strength of the protection baffle, saving manufacturing materials, and reducing manufacturing costs.

[0013] The electrical equipment electrical cabinet provided by the application comprises an electrical cabinet body, a switch door for sealing protection, a controller for controlling different devices, and a heat dissipation hole main body symmetrically provided on the side surface of the electrical cabinet body.
