Four corners of the bottom of the power box main body are fixedly connected with support legs. A partition is fixedly connected inside the power box main body. Two placement boxes are placed on the bottom inner wall of the power box main body. First guiding plates are fixedly connected to both inner walls on two sides of the power box main body. First guiding grooves are formed on one side of each of the two placement boxes away from each other. The first guiding plates are clamped with the first guiding grooves. The desiccant in the placement boxes can effectively perform moisture-proof treatment on the power box main body. By setting a blower, it is convenient to perform heat-dissipating treatment on the power box main body, improving the service life of the electrical devices inside the power box main body. Push the pull plate, the pull plate stretches the spring, the pull plate drives the limiting plate and the active plate to move, so that the limiting plate moves out of the limiting groove, and the active plate drives the pressing plate to move through hydraulic oil, so that the pressing plate is separated from the placement box. At this time, the limitation on the first guiding plate and the second guiding plate is released, and then the blower is pulled to conveniently remove the blower for maintenance, and at the same time, it is convenient to remove the placement box to facilitate the replacement of the desiccant inside the placement box.

[0004] In the above power box, when installing the power box, when the side wall of the power box is installed against the wall, it may cause the heat dissipation holes on the side wall of the power box to be too close to the wall, thereby reducing the space for air circulation, resulting in poor heat dissipation effect, and the hot air cannot be effectively discharged, causing damage to the electrical equipment inside the power box.

[0007] According to the above technical solution, a fixing plate is fixed on the side wall of the box body, a pressing rod is fixed on the side wall of the fixing plate, and the outer wall of the pressing rod fits with the inner wall of the connecting groove. When the side plate moves into the box body, the connecting groove will move on the pressing rod, so that the pressing rod can press the drainage plate to rotate, facilitating drainage operation.

[0008] According to the above technical solution, the auxiliary component includes a connecting block, a hinged rod, a pushing block, a conveyor belt, a first bevel gear, a rotating rod, a rotating shaft, a second bevel gear, a supporting block, a pushing plate, a rotating plate and a connecting column; The connecting block is fixed on the side wall of the side plate, the top of the box body is penetrated by a pushing block, and the penetration part is slidably connected. The bottom of the pushing block is hinged with a hinged rod, and the end of the hinged rod away from the pushing block is hinged on the side wall of the connecting block. When the side plate moves, it can drive the connecting block to move, so that the connecting block presses the hinged rod, making the hinged rod rotate at the hinge, so that the hinged rod can press the pushing block to move upward, and the pushing block can press the top plate to tilt slightly.

Through the cooperation of the driving pulley, the conveyor belt and the driven pulley, it can drive the rotating rod and the first bevel gear to rotate, so as to drive the second bevel gear and the rotating shaft to rotate, making the rotating shaft drive the rotating plate to rotate, and making the connecting column rotate at the middle position of the push plate, squeezing the push plate to drive the support plate and the electrical equipment to move.

[0012] According to the above technical solution, the extension assembly includes a square frame, a sleeve, a sleeve rod, a connecting spring, a moving plate, an L-shaped sliding plate, a limiting rod, a limiting hole, a movable rod, a pushing spring and an extension plate.

A connecting spring is fixed at the top of the sleeve rod. The top of the connecting spring is fixed on the inner wall of the sleeve. A moving plate is fixed at the bottom of the sleeve rod. When the top plate rotates slightly, it will cause the moving plate to press against the square frame, so that the moving plate can drive the sleeve rod to move into the sleeve under the extrusion force, compressing the connecting spring.

[0013] According to the above technical solution, an L-shaped sliding plate is slidably installed at the bottom of the top plate. A limiting rod is fixed on the inner side of the L-shaped sliding plate. An extension plate is slidably installed on the inner side of the top plate.

One end of the movable rod away from the L-shaped sliding plate is hinged to the moving plate. When the moving plate moves upward, it will cause the moving plate to press the movable rod to rotate at the hinge, so that the movable rod presses the L-shaped sliding plate to move, driving the limiting rod to move out of the limiting hole, so as to release the limit on the extension plate.

[0014] The present invention provides a power cabinet with a protection function for electrical automation. It has the following beneficial effects:

[0015] 1. When the box body of the present invention is installed against the wall, the transmission plate will be squeezed against the wall, so that the connecting rod can drive the moving block to move, driving the side plate on the wall side to move into the box body, so that the heat dissipation holes are far away from the wall, leaving a certain space between the heat dissipation holes and the wall, thus facilitating the heat dissipation operation and preventing the distance between the heat dissipation holes and the wall from being too close, reducing the air circulation space and resulting in poor heat dissipation effect. And when the side plate moves into the box body, through the cooperation of the extrusion rod and the connecting groove, the drainage plate will be rotated under the extrusion force, making the drainage plate inclined on the side plate close to the wall. When it rains, it is convenient for the rainwater to flow through the drainage plate to the ground, preventing the rainwater from accumulating at the bottom inside the box body and making it easy for the rainwater to enter the box body from the gap between the side plate and the inner bottom of the box body, causing damage to the electrical equipment.

[0016] 2. When the side plate moves, it can drive the connecting block to move, squeezing the articulated rod by the connecting block, causing the articulated rod to rotate at the articulated part, pushing the push block upward, and the push block pushes the top plate of the box body to tilt away from the wall, so that the rainwater can be conveniently drained from the side away from the wall, preventing a large amount of rainwater on the top plate from flowing to the side close to the wall, which is likely to cause water accumulation at the wall and is inconvenient for draining the rainwater. And when the top plate rotates, it can drive the rotating column to rotate. Through the cooperation of the driving transmission wheel, the conveyor belt, the driven transmission wheel, the rotating rod, the first bevel gear, the second bevel gear, the rotating shaft, the rotating plate, the connecting column and the push plate, the push plate can drive the support plate and the electrical equipment away from the wall, preventing excessive moisture at the wall from easily entering the box body through the heat dissipation holes, causing damage to the electrical equipment.

[0017] 3. When the top plate rotates, it will squeeze the moving plate against the square frame, causing the moving plate to move upward on the top plate under the extrusion force. Through the cooperation of the movable rod and the L-shaped sliding plate, the limiting rod is removed from the limiting hole, releasing the limit on the extension plate. Through the cooperation of the pushing spring, the extension plate away from the wall can be driven to move out of the top plate, so that when the rainwater drains to the ground, the flowing rainwater can be far away from the heat dissipation holes and the side plate, preventing a large amount of rainwater from flowing at the side plate, resulting in the rainwater easily entering the box body from the gap between the heat dissipation holes and the side plate.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-8, an embodiment of the present invention is: a power cabinet with a protection function for electrical automation, including a box body 1, a side plate 2 is attached to the inner wall of the box body 1, a hinge seat 3 is fixed to the top of the box body 1, a rotating column 4 is rotatably installed inside the hinge seat 3, a rotating block 5 is fixed to the outer wall of the rotating column 4, a top plate 6 is fixed to the top of the rotating block 5, a torsion spring is fixed to the side wall of the rotating block 5, and one side of the torsion spring away from the rotating block 5 is fixed inside the hinge seat 3. A support plate 7 is slidably installed on the inner wall of the box body 1, and an electrical device 8 is detachably installed at the bottom of the support plate 7. A protection component for preventing heat dissipation from being affected is provided on the box body 1. Among them, the protection component includes a moving block 91, a transmission spring 92, a connecting rod 93, a transmission plate 94, a drainage plate 95, a connection groove 96, a fixing plate 98, and a pressing rod 97; the moving block 91 is slidably installed on the inner wall of the box body 1, the top of the moving block 91 is fixedly connected to the bottom of the side plate 2, a transmission spring 92 is fixed to one side of the moving block 91, a connecting rod 93 is fixed to the other side of the moving block 91, one end of the connecting rod 93 away from the moving block 91 is fixed to a transmission plate 94, a drainage plate 95 is hinged to the side wall of the side plate 2, a connection groove 96 is opened on the side wall of the drainage plate 95, a fixing plate 98 is fixed to the side wall of the box body 1, a pressing rod 97 is fixed to the side wall of the fixing plate 98, and the outer wall of the pressing rod 97 fits with the inner wall of the connection groove 96.

[0029] There are two sets of transmission plates 94, and the two sets of transmission plates 94 are symmetrically arranged with the central axis of the box body 1 in the vertical direction as the axis of symmetry. By setting the transmission plates 94, when installing the equipment against the wall, the side wall installed on the edge of the wall will contact the transmission plates 94 and be subjected to a squeezing force, so as to drive the side plate 2 near the wall to move into the box body 1, leaving a certain space between the heat dissipation holes and the wall, thus facilitating the heat dissipation operation and preventing the distance between the heat dissipation holes and the wall from being too close, reducing the air circulation space and resulting in poor heat dissipation effect.

[0030] There are two sets of drainage plates 95, and the two sets of drainage plates 95 are symmetrically arranged with the central axis of the box body 1 in the vertical direction as the axis of symmetry. When the side plate 2 near the wall moves, through the cooperation of the pressing rod 97 and the connection groove 96, the drainage plate 95 near the wall will rotate and be inclined on the side plate 2. When it rains, the rainwater will be diverted from the drainage plate 95 and flow to the ground, preventing the rainwater from accumulating at the bottom inside the box body 1 and making it easy for the rainwater to enter the box body 1 from the gap between the side plate 2 and the bottom inside of the box body 1, causing damage to the electrical device 8.

[0031] During the operation of this embodiment: When installing the power box on the outdoor wall, when the side wall of the power box is installed too close to the wall surface, the transmission plate 94 will come into contact with the wall surface and be subjected to extrusion force, enabling the transmission plate 94 to drive the connecting rod 93 to move and push the moving block 91 to move into the box body 1, thereby driving the side plate 2 on the side close to the wall surface to move into the box body 1. When the moving block 91 moves, the transmission spring 92 can be compressed. When the side plate 2 close to the wall surface moves into the box body 1, the heat dissipation holes can be kept away from the wall surface, leaving a certain space between the heat dissipation holes and the wall surface, thus facilitating the heat dissipation operation; and when the side plate 2 close to the wall surface moves into the box body 1, the connecting groove 96 of the drain plate 95 will move on the extrusion rod 97, causing the extrusion rod 97 to extrude the inner wall of the connecting groove 96. Due to the extrusion force, the drain plate 95 will rotate on the side plate 2 and be inclined on the side plate 2, thus facilitating the drainage operation. When it rains, the flowing rainwater will flow from the drain plate 95 to the ground, preventing the rainwater from flowing to the inner side of the bottom of the box body 1 and accumulating, which is likely to cause the rainwater to enter the box body 1 through the gaps of the side plate 2;

[0032] When the power box is disassembled from the wall and not installed on the wall, since the transmission plate 94 is not extruded by the wall surface and the transmission spring 92 is in a compressed state, the transmission spring 92 can drive the moving block 91 to reset, the side plate 2 to reset, and the space inside the box body 1 to become larger, facilitating the subsequent maintenance work of the staff. And when the side plate 2 resets, the side plate 2 drives the drain plate 95 to reset, the connecting groove 96 continues to move on the extrusion rod 97, and the extrusion rod 97 extrudes the drain plate 95 to rotate towards the side plate 2 direction, so that the drain plate 95 is retracted to prevent it from being in an unfolded state all the time, which is rather obstructive.

[0033] Please refer to Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the top of the box body 1 is provided with an auxiliary component for adjusting the top plate 6, which also includes an extension component; the auxiliary component includes a connecting block 101, a hinged rod 102, a push block 103, a conveyor belt 104, a first bevel gear 106, a rotating rod 105, a rotating shaft 107, a second bevel gear 108, a supporting block 109, a push plate 110, a rotating plate 111 and a connecting column 112; the connecting block 101 is fixed to the side wall of the side plate 2, the top of the box body 1 is penetrated by a push block 103, and the penetration is slidably connected, the bottom of the push block 103 is hinged with a hinged rod 102, and one end of the hinged rod 102 away from the push block 103 is hinged to the side wall of the connecting block 101, the inner wall of the box body 1 is rotatably installed with a rotating rod 105, the outer wall of the rotating column 4 is fixed with a driving pulley, and the outer wall of the rotating rod 105 is fixed with a driven pulley, and the driving pulley and the transmission pulley are transmitted through The transmission connection is made by belt 104, and the radius of the driving pulley is three times the radius of the driven pulley. When the driving pulley rotates slightly, the driven pulley can rotate with a larger amplitude. The outer wall of the rotating rod 105 is fixed with a No. 1 bevel gear 106, and the inner wall of the box body 1 is fixed with a support block 109. A rotating shaft 107 passes through the support block 109, and the penetration is rotatably connected. The setting of the support block 109 can support the rotating shaft 107. The outer wall of the rotating shaft 107 is fixed with a No. 2 bevel gear 108, and the outer wall of the No. 1 bevel gear 106 is meshed with the outer wall of the No. 2 bevel gear 108. The top of the rotating shaft 107 is fixedly connected to the bottom of the No. 2 bevel gear 108, and the top of the support plate 7 is fixed with a push plate 110, and the bottom of the rotating shaft 107 is fixed with a rotating plate 111. The bottom of the rotating plate 111 is fixed with a connecting column 112, and the outer wall of the connecting column 112 fits the inner side of the push plate 110.

[0034] Because the top plate 6 can be rotated on the top of the box body 1, when the power box is installed on the wall, the top plate 6 on the power box will be slightly rotated downward away from the wall, so that rainwater can be easily drained from the side away from the wall, preventing a large amount of rainwater on the top plate 6 from flowing to the side close to the wall, which may easily cause water accumulation on the wall and make it inconvenient to drain the rainwater.

[0035] And when the top plate 6 rotates slightly downward away from the wall, the rotating column 4 can be rotated. Through the cooperation of the active transmission wheel, the conveyor belt 104, the driven transmission wheel, the rotating rod 105, the first bevel gear 106, the second bevel gear 108, the rotating shaft 107, the rotating plate 111, the connecting column 112 and the push plate 110, the push plate 110 can drive the support plate 7 and the electrical equipment 8 away from the wall to prevent excessive moisture on the wall, which may easily cause a large amount of moisture to enter the box body 1 through the heat dissipation holes and cause damage to the electrical equipment 8.

[0036] The extension component includes a square frame 12, a sleeve 13, a sleeve rod 14, a connecting spring 15, a moving plate 16, an L-shaped sliding plate 17, a limiting rod 18, a limiting hole 21, a movable rod 19, a pushing spring 22 and an extension plate 20. The square frame 12 is fixed on the top of the box body 1. A sleeve 13 is fixed to the bottom of the top plate 6. A sleeve rod 14 is slidably installed on the inner wall of the sleeve 13. The top of the sleeve rod 14 is fixed with a connecting spring 15. The top of the connecting spring 15 is fixed to the inner wall of the sleeve 13. The bottom of the sleeve rod 14 is fixed with a moving plate 16. An L-shaped sliding plate 17 is slidably installed on the bottom of the top plate 6. A limiting rod 18 is fixed to the inner side of the L-shaped sliding plate 17. An extension plate 20 is slidably installed on the inner side of the top plate 6. A limiting hole 21 is formed in the side wall of the extension plate 20. The inner wall of the limiting hole 21 fits with the outer wall of the limiting rod 18. One end of a movable rod 19 away from the L-shaped sliding plate 17 is hinged to the moving plate 16.

[0037] The diameter of the limiting rod 18 matches the diameter of the limiting hole 21. Through the cooperation of the limiting rod 18 and the limiting hole 21, the effect of fixing the extension plate 20 can be achieved, so that the extension plate 20 is fixed in the top plate 6.

[0038] There are two groups of extension plates 20, and the two groups of extension plates 20 are symmetrically arranged with the central line of the box body 1 in the vertical direction as the axis of symmetry. When the limiting rod 18 is removed from the limiting hole 21, the limitation of the extension plate 20 can be released. Through the cooperation of the pushing spring 22, the extension plate 20 far from the wall can be driven to move out of the top plate 6. Thus, when draining the rainwater on the top plate 6, when the rainwater drains to the ground, the flowing rainwater can be far away from the heat dissipation holes and the side plate 2, and it can prevent a large amount of rainwater from flowing at the side plate 2, resulting in the rainwater easily entering the box body 1 from the gap between the heat dissipation holes and the side plate 2.

[0039] During the operation of this embodiment: when the side plate 2 near the wall moves into the box body 1, the side plate 2 can drive the connecting block 101 to move, so that the connecting block 101 squeezes the hinge rod 102, causing the hinge rod 102 to rotate at the hinge, and then the hinge rod 102 can squeeze a push block 103 near the wall to move upward. When the push block 103 moves upward to squeeze the bottom of the top plate 6 near the wall surface, the top plate 6 can be slightly rotated downward away from the wall, which is convenient for subsequent drainage of the top plate 6, so that a large amount of water on the top plate 6 can be easily drained away from the side away from the wall, preventing a large amount of water from accumulating near the wall surface. And when the top plate 6 rotates slightly downward away from the wall surface, it can drive the rotating block 5 and the rotating column 4 to rotate away from the wall surface, so that the driving pulley on the rotating column 4 rotates. Through the conveyor belt 104, the driven pulley can be driven to rotate away from the wall surface, causing the rotating shaft 107 to rotate, and the rotating shaft 107 can drive the rotating plate 111 to rotate, so that the connecting column 112 can squeeze the inner side of the push plate 110, causing the push plate 110 to move away from the wall surface, and the push plate 110 drives the support plate 7 away from the wall surface, so that the support plate 7 can drive the electrical equipment 8 away, preventing excessive moisture near the wall surface from easily entering the box body 1 through the heat dissipation holes. And when the top plate 6 inclines downward away from the wall surface, it will drive the moving plate 16 away from the wall surface to move downward, and the bottom of the moving plate 16 will contact the top of the square frame 12, so that the moving plate 16 will be driven by the extrusion force to drive the sleeve rod 14 to move into the sleeve 13, compressing the connecting spring 15. And when the moving plate 16 approaches the top plate 6, the moving plate 16 will squeeze the movable rod 19, causing the movable rod 19 to rotate at the hinge, so that the movable rod 19 can squeeze the L-shaped sliding plate 17 to move, and the L-shaped sliding plate 17 can drive the limiting rod 18 to move out of the limiting hole 21, releasing the limit on the extension plate 20 away from the wall surface. Because the pushing spring 22 is in a compressed state, the pushing spring 22 can drive the extension plate 20 to move out of the top plate 6, so that when the rainwater drains away from the top plate 6 away from the wall surface, the flowing rainwater can be away from the heat dissipation holes and the side plate 2.

[0040] When the driving spring 92 drives the side plate 2 to reset, the side plate 2 can drive the connecting block 101 to move, and the connecting block 101 pulls the hinge rod 102 to reset, so that the push block 103 does not squeeze the top plate 6. Since the torsion spring is in a compressed deformation state, the torsion spring can drive the top plate 6 to reset to a horizontal state. And when the top plate 6 resets, the rotating column 4 can rotate and reset. Through the cooperation of the driving pulley, the conveyor belt 104, the driven pulley, the first bevel gear 106, the second bevel gear 108, the rotating rod 105, the rotating shaft 107 and the rotating plate 111, the connecting column 112 can squeeze the push plate 110 to return to its original position, so that the support plate 7 can drive the electrical equipment 8 to return to its original position. And when the extension plate 20 extends out, since the limiting rod 18 abuts against the outer wall of the extension plate 20 and keeps the connecting spring 15 in a compressed state all the time. When the top plate 6 returns to the horizontal state, it pushes the extended extension plate 20 into the top plate 6, so that the extension plate 20 squeezes and compresses the pushing spring 22. And when the extension plate 20 moves to align the limiting hole 21 with the limiting rod 18, since the connecting spring 15 is in a compressed state, the sleeve rod 14 can move downward. Through the cooperation of the moving plate 16 and the movable rod 19, the movable rod 19 can pull the L-shaped sliding plate 17 to reset, so that when the limiting rod 18 extends into the limiting hole 21, the extension plate 20 is fixed in the top plate 6 for storage, preventing it from being in the unfolded state all the time, which is rather in the way.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
