Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and particularly to an outdoor power cabinet with an anti-collision structure. Background Art

[0002] With the continuous development of power infrastructure, outdoor power cabinets are widely used in urban and rural power grids, industrial parks and other places, undertaking key tasks such as power distribution and circuit control. However, the outdoor environment is complex and changeable, and power cabinets face many collision risks. On the one hand, passing vehicles and construction equipment may hit the power cabinet due to operational errors or accidental out-of-control, resulting in deformation of the cabinet body and damage to internal electrical equipment, affecting the stability and safety of power supply. On the other hand, the natural environment is harsh in some areas. For example, strong winds and heavy rains may cause trees to fall and hit the power cabinet, or in snowy and frozen areas, falling ice crystals will also impact it.

[0003] An outdoor power cabinet with an anti-collision function, with the patent publication number CN207339000U, includes a power cabinet body. The bottom of the power cabinet body is fixedly connected with a base. Two symmetrically arranged clamping grooves are opened on the upper surface of the base. Two symmetrically arranged grooves are opened in the middle of the outer side of the power cabinet body. A fixed column is fixedly connected inside each groove, and a cavity is opened inside each fixed column. This outdoor power cabinet with an anti-collision function utilizes the elasticity of the first spring to ensure the effective telescoping of the movable rod, enabling the first anti-collision plate to move flexibly, thereby buffering external forces. Utilizing the elasticity of the second spring, it ensures the flexible movement of the second anti-collision plate in the notch, capable of buffering external impacts, providing multi-directional protection for the power cabinet, effectively avoiding damage to the power cabinet, having good anti-collision performance, and effectively ensuring the service life of the power cabinet.

[0004] However, the above power cabinet can only provide simple protection and buffering for external impacts. When subjected to relatively violent impacts, such as the collision caused by a car accident, the protective effect on the power cabinet is relatively limited. When the power cabinet is subjected to a violent impact, the above base, fixed column and anti-collision plate may all be deformed by the collision, directly damaging the internal electrical equipment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an outdoor power cabinet with an anti-collision structure, solving the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An outdoor power cabinet with an anti-collision structure, including a power cabinet housing, a cover plate is hinged on the upper surface of the power cabinet housing, a heat dissipation port is opened on the back surface of the power cabinet housing, an electrical device slides on the inner wall of the power cabinet housing, a buffer device for protecting the power cabinet housing when it is collided is arranged on the side wall of the power cabinet housing, a stabilizing device for fixing wires is arranged in the power cabinet housing, and a shielding device for facilitating rain shielding is arranged on the electrical device; wherein, the buffer device includes a fixed block, a fixed rod, a slider, a buffer spring, a first hinge rod, a buffer plate, a limiting block, a clamping block, a first spring rod, a second hinge rod, a connecting block and a mounting plate. The fixed block is fixedly connected to the side wall of the outer wall of the power cabinet housing, a fixed rod is fixed in the fixed block, and the fixed rod penetrates through the slider and is slidably connected at the penetration point.

[0007] According to the above technical solution, one end of the side wall of the slider is fixedly connected to one end of the buffer spring, and the other end of the buffer spring is fixedly connected to the side wall of the fixed block. When the slider slides, the buffer spring is compressed, and the buffer spring offsets part of the impact force through its own elastic potential energy. One end of the first hinge rod is hinged to the side wall of the slider away from the power cabinet housing, and the other end of the first hinge rod away from the slider is hinged to the buffer plate. When the buffer plate is impacted, it drives the first hinge rod to rotate and transmits the impact force to the buffer spring.

[0008] According to the above technical solution, a limiting block is fixed to the side wall of the buffer plate close to the power cabinet housing. The limiting block penetrates through the side wall of the power cabinet housing and is slidably connected at the penetration point. When the buffer plate moves, it drives the limiting block to slide. A clamping block is fixed to the bottom surface of the cover plate, and the inner walls of the clamping block and the limiting block are fitted. The limiting block limits the clamping block. A first spring rod is fixed to the bottom surface of the cover plate, and the end of the first spring rod away from the cover plate is fixedly connected to the inner wall of the power cabinet housing. When the cover plate is released from the limit, it is opened by the elastic force of the first spring rod.

[0009] According to the above technical solution, a second hinge rod is hinged to the bottom surface of the cover plate. When the cover plate bounces open, it drives the second hinge rod to move and rotate. The other end of the second hinge rod away from the cover plate is hinged to the inner wall of the connecting block. When the second hinge rod rotates, it drives the connecting block to move upward. A mounting plate is fixed to the side wall of the connecting block. When the connecting block moves upward, it drives the mounting plate to slide upward. The upper surface of the mounting plate is fixedly connected to the bottom surface of the electrical device. When the mounting plate slides upward, it drives the electrical device to pop out from above the power cabinet housing.

[0010] According to the above technical solution, the stabilizing device includes a top rod, a return spring, a baffle, a movable rod, a guide strip, a third hinge rod, a sliding rod and a top block. The top rod is fixed inside the power cabinet housing, and the side wall of the electrical equipment is fixed with a return spring. When the return spring is inside the power cabinet housing, it is in a compressed state under the thrust of the top rod. One end of the return spring away from the electrical equipment is fixed with a baffle. When the electrical equipment pops out, the baffle slides outwards under the thrust of the return spring.

[0011] According to the above technical solution, a sliding groove is provided on the side wall of the baffle. The movable rod slides on the inner wall of the sliding groove. When the baffle slides, it drives the movable rod to move. The guide strip is fixed on the front surface of the electrical equipment. One end of the movable rod passes through the third hinge rod and is rotatably connected at the passing position. The movement of the movable rod drives the third hinge rod to move and rotate. There are two groups of the third hinge rods. The side walls of the upper third hinge rod and the lower third hinge rod are in contact with each other.

[0012] According to the above technical solution, the sliding rod slides on the outer wall of the guide strip. The side wall of the sliding rod is hinged to the end of the third hinge rod away from the movable rod. When the third hinge rod rotates, it drives the sliding rod to slide up and down along the guide strip. The bottom surface of the sliding rod is fixed with an inclined block. A guide rail is provided on the inclined block. The top block slides on the inner wall of the guide rail. The side wall of the top block is in sliding connection with the inclined surface of the inclined block. When the sliding rod slides up and down, the top block slides along the guide rail.

[0013] According to the above technical solution, the shielding device includes a second spring rod, a rain shield and a limiting plate. The second spring rod is in a stretched state inside the power cabinet housing. One end of the second spring rod is fixedly connected to the upper surface of the electrical equipment. The rain shield is hinged to the front surface of the electrical equipment. The other end of the second spring rod is fixedly connected to the upper surface of the rain shield. When the rain shield is released from the limit, the second spring rod drives the rain shield to open. The limiting plate is fixed on the upper surface of the upper sliding rod. When the sliding rod slides, it drives the limiting plate to move downwards, releasing the limit on the rain shield. The upper end of the limiting plate slides on the inner wall of the rain shield. The side wall of the rain shield is hinged with a fourth hinge rod. The side plate slides on the side wall of the electrical equipment. The end of the fourth hinge rod away from the rain shield is hinged to the side wall of the side plate.

[0014] The present invention provides a power cabinet with an anti-collision structure outdoors, having the following beneficial effects:

[0015] 1. In the normal situation of the present invention, through the cooperation of a buffer plate, a first hinge rod, a slider, and a buffer spring, when being impacted, the impact force received is transferred to the buffer spring, enabling a part of the elastic force of the buffer spring to cancel out the impact force mutually, achieving the effect of buffering when being collided, avoiding the direct impact on the shell of the power cabinet and damaging the internal electrical equipment; when the impact force is too large, the buffer plate drives the limit block to move, releasing the limit of the cover plate, so that the cover plate is pushed open by the thrust of the first spring rod. When the cover plate is pushed open, by driving the second hinge rod, cooperating with the connecting block and the mounting plate to drive the electrical equipment to rise, avoiding that when the shell of the power cabinet is impacted greatly, the buffering effect is limited, the shell of the power cabinet is easily impacted to form a depression, and the internal electrical equipment is easily damaged. When the device is impacted greatly, it can eject the electrical equipment from above, avoiding the situation that the electrical equipment is damaged by the sunken shell of the power cabinet.

[0016] 2. In the present invention, when the electrical equipment is ejected, the baffle is disengaged from the ejector rod. Since the return spring is always in a compressed state, when moving away from the ejector rod, the baffle can be ejected by the thrust of the return spring. When the baffle is ejected, it pulls the movable rod and the electrical equipment to move away from each other. The movable rod pulls the third hinge rod to rotate, and the third hinge rod drives the sliding rods to approach each other, clamping the electric wire while the electrical equipment is ejected, avoiding that when the electrical equipment is ejected, the electric wire is pulled off from the interface, affecting the normal use of the power cabinet; while the sliding rods approach each other to clamp the electric wire, the inclined plane blocks on their inner walls squeeze the top block, pushing the top block to slide along the guide rail, pushing the electric wire towards the interface, promoting the stable clamping effect of the electric wire, so that the interface can be stably inserted into the electrical equipment to prevent detachment.

[0017] 3. In the present invention, when the shell of the power cabinet is impacted violently and the electrical equipment is ejected, the limit of the rain shield by the limit plate is released through the sliding of the sliding rod, and the rain shield is rotated by cooperating with the second spring rod to make the rain shield in the shape of an eave, protecting the electrical equipment below. At the same time, it pulls the fourth hinge rod to cooperate with the side plate to slide, protecting the electrical equipment on the side, avoiding that when the shell of the power cabinet ejects the electrical equipment, the external environment is relatively extreme, causing the electrical equipment to get water and be damaged.

[0028] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-9 , an embodiment of the present invention is: A power cabinet with an anti-collision structure outdoors, including a power cabinet housing 1, a cover plate 2 is hinged on the upper surface of the power cabinet housing 1, a heat dissipation port 4 is opened on the back surface of the power cabinet housing 1, an electrical equipment 3 slides on the inner wall of the power cabinet housing 1, and a buffer device 5 for protecting the power cabinet housing 1 when it is collided is provided on the side wall of the power cabinet housing 1.

[0030] Among them, the buffer device 5 includes a fixed block 51, a fixed rod 52, a slider 53, a buffer spring 54, a first hinge rod 55, a buffer plate 56, a limit block 57, a clamping block 58, a first spring rod 59, a second hinge rod 510, a connecting block 511 and a mounting plate 512. The fixed block 51 is fixedly connected to the side wall of the outer wall of the power cabinet housing 1. A fixed rod 52 is fixed in the fixed block 51. The fixed rod 52 passes through the slider 53 and is slidably connected at the penetration point. One end of the side wall of the slider 53 is fixedly connected to one end of the buffer spring 54. When the slider 53 slides, it compresses the buffer spring 54. The elastic force of the buffer spring 54 cancels out part of the impact force received by the buffer plate 56 to buffer the possible collision of the power cabinet housing 1. The other end of the buffer spring 54 is fixedly connected to the side wall of the fixed block 51. One end of the slider 53 away from the side wall of the power cabinet housing 1 is hinged with a first hinge rod 55. While rotating, the first hinge rod 55 pushes the slider 53 to slide in a mutually separated direction. One end of the first hinge rod 55 away from the slider 53 is hinged with a buffer plate 56. When impacted from the side, the buffer plate 56 moves towards the power cabinet housing 1 under the influence of the impact force. When the buffer plate 56 moves towards the power cabinet housing 1, it drives the end of the first hinge rod 55 hinged to it to move towards the power cabinet housing 1. Also, the distance between the end of the first hinge rod 55 hinged to the slider 53 and the power cabinet housing 1 remains unchanged. Therefore, the first hinge rod 55 rotates while moving. A limit block 57 is fixed to the side wall of the buffer plate 56 close to the power cabinet housing 1. The buffer plate 56 drives the limit block 57 to slide. The limit block 57 passes through the side wall of the power cabinet housing 1 and is slidably connected at the penetration point. A clamping block 58 is fixed to the bottom surface of the cover plate 2. The inner walls of the clamping block 58 and the limit block 57 are fitted. When the limit block 57 slides, the part in contact with the clamping block 58 moves away. A first spring rod 59 is fixed to the bottom surface of the cover plate 2. The first spring rod 59 is always in a compressed state when the cover plate 2 is closed. When the cover plate 2 is no longer limited by the limit block 57, the cover plate 2 is pushed by the first spring rod 59 and rotates around its hinge point with the power cabinet housing 1 to flip and open the cover plate 2. When the cover plate 2 opens, it drives the end of the second hinge rod 510 hinged to it to rise. Also, the position of the end of the second hinge rod 510 away from the cover plate 2 remains unchanged in the horizontal direction. Therefore, the second hinge rod 510 rotates while rising. One end of the first spring rod 59 away from the cover plate 2 is fixedly connected to the inner wall of the power cabinet housing 1. The bottom surface of the cover plate 2 is hinged with a second hinge rod 510. One end of the second hinge rod 510 away from the cover plate 2 is hinged with the inner wall of the connecting block 511. The second hinge rod 510 drives the connecting block 511 to rise. A mounting plate 512 is fixed to the side wall of the connecting block 511. The connecting block 511 drives the mounting plate 512 to slide upward. The upper surface of the mounting plate 512 is fixedly connected to the bottom surface of the electrical equipment 3. The electrical equipment 3 above the mounting plate 512 pops up together with the mounting plate 512. Under normal circumstances, this buffer device 5, through the cooperation of the buffer plate 56, the first hinge rod 55, the slider 53 and the buffer spring 54,When being impacted, the impact force received is transferred to the buffer spring 54, so that part of the elastic force of the buffer spring 54 cancels out the impact force with each other, achieving the buffering effect when being collided, avoiding the direct impact on the power cabinet housing 1 and damaging the internal electrical equipment 3; when the impact force is too large, the buffer plate 56 drives the limit block 57 to move, releasing the limit of the cover plate 2, so that the cover plate 2 is pushed open by the first spring rod 59. When the cover plate 2 is pushed open, by driving the second hinge rod 510, cooperating with the connecting block 511 and the mounting plate 512 to drive the electrical equipment 3 to rise, avoiding that when the power cabinet housing 1 is impacted greatly, the buffering effect is limited, the power cabinet housing 1 is easily impacted and dented, and the internal electrical equipment 3 is easily damaged. However, when the device is impacted greatly, the electrical equipment 3 can be ejected from above, avoiding the situation that the electrical equipment 3 is damaged by the dented power cabinet housing 1.,

[0031] During the operation of this embodiment: When a lateral impact occurs, the buffer plate 56 moves towards the power cabinet housing 1 under the influence of the impact force. When the buffer plate 56 moves towards the power cabinet housing 1, it drives the end of the first hinge rod 55 hinged to it to move towards the power cabinet housing 1. Also, the distance between the end of the first hinge rod 55 hinged to the slider 53 and the power cabinet housing 1 remains unchanged. Therefore, the first hinge rod 55 rotates while moving. While rotating, the first hinge rod 55 pushes the slider 53 to slide in the direction away from each other. When the slider 53 slides, it compresses the buffer spring 54, and the elastic force of the buffer spring 54 cancels out part of the impact force received by the buffer plate 56, buffering the possible collision on the power cabinet housing 1. When the impact force is too large, the buffer plate 56 moves a greater distance towards the power cabinet housing 1, and the buffer plate 56 drives the limit block 57 to slide, making the part in contact with the latch 58 move away. The first spring rod 59 is always in a compressed state when the cover plate 2 is closed. When the cover plate 2 is no longer limited by the limit block 57, the cover plate 2 is pushed by the first spring rod 59 and rotates around its hinge point with the power cabinet housing 1, causing the cover plate 2 to flip open. When the cover plate 2 opens, it drives the end of the second hinge rod 510 hinged to it to rise. Also, the position of the end of the second hinge rod 510 away from the cover plate 2 remains unchanged in the horizontal direction. Therefore, the second hinge rod 510 rotates while rising. The second hinge rod 510 drives the connecting block 511 to rise, and the connecting block 511 drives the mounting plate 512 to slide upward, causing the electrical equipment 3 above the mounting plate 512 to pop out together with the mounting plate 512. When the maintenance personnel have completed the maintenance of the power cabinet housing 1 and the electrical equipment 3 and need to plug the electrical equipment 3 back into the power cabinet housing 1, they need to first press the buffer plate 56. The buffer plate 56 moves towards the power cabinet housing 1 and drives the limit block 57 to slide towards the center of the power cabinet housing 1. Then, fold the cover plate 2 so that the cover plate 2 compresses the first spring rod 59. After the cover plate 2 is completely closed, release the buffer plate 56. The sliders 53 are pushed by the buffer spring 54 to move closer to each other. The sliders 53 drive the first hinge rod 55 to rotate, and the first hinge rod 55 pushes the buffer plate 56 to move away from the power cabinet housing 1. The buffer plate 56 drives the limit block 57 to slide away from the center of the power cabinet housing 1, making the inner wall of the limit block 57 fit the inner wall of the latch 58 again to limit the cover plate 2 and fix the electrical equipment 3 in the power cabinet housing 1.

[0032] Please refer to Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, a stabilizing device 6 for fixing wires is provided inside the power cabinet housing 1, and a shielding device 7 for facilitating rain shielding is provided on the electrical equipment 3. The stabilizing device 6 includes a top rod 61, a return spring 62, a baffle 63, a movable rod 64, a guide strip 65, a third hinge rod 66, a sliding rod 67, and a top block 68. The top rod 61 is fixed to the inner wall of the power cabinet housing 1, and the return spring 62 is fixed to the side wall of the electrical equipment 3. The end of the return spring 62 away from the electrical equipment 3 is fixed with a baffle 63. When the cover plate 2 is closed, the return spring 62 is always in a compressed state under the thrust of the top rod 61 on the baffle 63. After being violently impacted, the electrical equipment 3 pops out from above, and the top rod 61 no longer exerts a thrust on the baffle 63 through the groove of the mounting plate 512. At this time, the baffle 63 slides away from the electrical equipment 3 under the thrust of the return spring 62, providing a simple secondary protection for the electrical equipment 3 on both the left and right sides of the electrical equipment 3. A sliding groove is provided on the side wall of the baffle 63, and the movable rod 64 slides on the inner wall of the sliding groove. The baffle 63 drives the movable rod 64 to move away from the electrical equipment 3. The guide strip 65 is fixed to the front of the electrical equipment 3. One end of the movable rod 64 penetrates through the third hinge rod 66, and the penetration part is rotatably connected. The movable rod 64 drives one end of the third hinge rod 66 to move away from the electrical equipment 3. Since the distance between the other end of the third hinge rod 66 and the electrical equipment 3 remains unchanged, the third hinge rod 66 is driven to rotate when the baffle 63 slides. There are two groups of the third hinge rods 66. The side walls of the upper third hinge rod 66 and the lower third hinge rod 66 are in contact with each other. The sliding rod 67 slides on the outer wall of the guide strip 65. When the third hinge rod 66 rotates, it drives the upper sliding rod 67 and the lower sliding rod 67 to approach each other along the direction of the guide strip 65, clamping the wire inserted into the electrical equipment 3. The side wall of the sliding rod 67 is hinged to the end of the third hinge rod 66 away from the movable rod 64. The bottom surface of the sliding rod 67 is fixed with an inclined block, and a guide rail is provided on the inclined block. The top block 68 slides on the inner wall of the guide rail. The side wall of the top block 68 is in sliding connection with the inclined surface of the inclined block. When the sliding rods 67 approach each other, the inclined blocks at their bottoms push the top block 68 to slide along the guide rail towards the electrical equipment 3, pushing the wire inward. When the power cabinet housing 1 is violently impacted and the electrical equipment 3 pops out, the stabilizing device 6 can pop out the baffle 63 through the thrust of the return spring 62, protecting the electrical equipment 3 when it pops out of the power cabinet housing 1, avoiding a secondary impact and directly hitting the electrical equipment 3, causing damage. When the baffle 63 pops out, it drives the sliding rods 67 to approach each other through the cooperation of the movable rod 64 and the third hinge rod 66, clamping the wire while the electrical equipment 3 pops out, preventing the wire from falling off from the interface due to the pulling force when the electrical equipment 3 pops out; while the sliding rods 67 approach each other and clamp the wire, the inclined blocks inside them squeeze the top block 68, pushing the top block 68 to slide along the guide rail, pushing the wire towards the interface, promoting the clamping stability effect of the wire.

[0033] Among them, the shielding device 7 includes a second spring rod 71, a rain shield 72 and a limiting plate 73. When the electrical device 3 is not ejected, the second spring rod 71 is always in a stretched state due to the rain shield 72 being restricted. One end of the second spring rod 71 is fixedly connected to the upper surface of the electrical device 3. The rain shield 72 is hinged to the front surface of the electrical device 3. The other end of the second spring rod 71 is fixedly connected to the upper surface of the rain shield 72. When the rain shield 72 is released from the restriction, the rain shield 72 is flipped open under the tension of the second spring rod 71. The material of the hinge of the rain shield 72 is rubber. When the rain shield 72 is unfolded, the rubber will abut against the front surface of the electrical device 3, forming a sealed environment above, so as to prevent rainwater from flowing onto the electrical device 3 from the hinge of the rain shield 72. A limiting plate 73 is fixed on the upper surface of the upper sliding rod 67 above. The upper end of the limiting plate 73 is slidably connected to the inner wall of the rain shield 72. When the upper sliding rod 67 slides downward, it drives the limiting plate 73 to move downward as well. The limiting plate 73 moves downward until it disengages from the groove of the rain shield 72. A fourth hinge rod 74 is hinged to the side wall of the rain shield 72. When the rain shield 72 is opened, it pulls the fourth hinge rod 74 to rotate. A side plate 75 slides on the side wall of the electrical device 3. The end of the fourth hinge rod 74 away from the rain shield 72 is hinged to the side wall of the side plate 75. When the fourth hinge rod 74 rotates, it pulls the side plate 75 to slide out, shielding the electrical device 3 from the side. When the power cabinet housing 1 is violently impacted and the electrical device 3 is ejected, the shielding device 7 can release the restriction of the limiting plate 73 on the rain shield 72 through the sliding of the sliding rod 67, and cooperate with the second spring rod 71 to rotate the rain shield 72 so that the rain shield 72 is in the shape of an eaves, protecting the electrical device 3 below. At the same time, it pulls the fourth hinge rod 74 to cooperate with the sliding of the side plate 75 to protect the electrical device 3 from the side, avoiding the external environment being extremely extreme when the power cabinet housing 1 ejects the electrical device 3, causing the electrical device 3 to get water and be damaged.

[0034] When the present embodiment is working, the return spring 62 is always in a compressed state due to the thrust of the push rod 61 on the baffle 63 when the cover 2 is closed. When it is violently hit, the electrical device 3 pops up from the top, and the push rod 61 passes through the groove of the mounting plate 512 and no longer exerts a thrust on the baffle 63. At this time, the baffle 63 slides in a direction away from the electrical device 3 due to the thrust of the return spring 62, and a simple secondary protection is provided to the electrical device 3 on the left and right of the electrical device 3. At the same time, the baffle 63 drives the movable rod 64 to move in a direction away from the electrical device 3, and the movable rod 64 drives one end of the third hinged rod 66 to move in a direction away from the electrical device 3, and the third hinged rod 66 is again engaged. The distance between the other end and the electrical equipment 3 remains unchanged, so the third hinged rod 66 is driven to rotate when the baffle 63 slides. When the third hinged rod 66 rotates, it drives the upper sliding rod 67 and the lower sliding rod 67 to approach each other along the direction of the guide strip 65, clamping the wires inserted into the electrical equipment 3. When the sliding rods 67 approach each other, the inclined block at the bottom pushes the top block 68 to slide along the guide rail in the direction of the electrical equipment 3, pushing the wires inward. When the maintenance is completed, when the electrical equipment 3 is stuffed back into the power cabinet housing 1, the baffle 63 is pushed toward the direction of the electrical equipment 3, and the baffle 63 is supported by the top rod 61 after the top rod 61 passes through the mounting plate 512.

[0035] When the second spring rod 71 does not pop out the electrical equipment 3, the rain shield plate 72 is limited and has been in a stretched state. When the upper sliding rod 67 slides downward, the limiting plate 73 also moves downward. The limiting plate 73 moves downward to disengage from the groove of the rain shield plate 72. At the same time, the rain shield plate 72 is folded open by the pulling force of the second spring rod 71. The rain shield plate 72 pulls the fourth hinge rod 74 to rotate. The fourth hinge rod 74 drives the side plate 75 to slide out, shielding the electrical equipment 3 from the top and the side. After the maintenance is completed, The rain shield 72 is folded to fit the electrical equipment 3, and the rain shield 72 pushes the fourth hinged rod 74 to rotate. The fourth hinged rod 74 pushes the side panel 75 back to its original position. When the baffle 63 slides in the direction of the electrical equipment 3, it drives the third hinged rod 66 to rotate. The third hinged rod 66 drives the two sets of sliding rods 67 away from each other. When the upper sliding rod 67 slides upward, it drives the limit plate 73 to move upward. The rain shield 72 is limited and stuck by the limit plate 73, so that the rain shield 72 is always in a folded state, which is convenient for inserting into the power cabinet housing 1.
