Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets with a drying function, and specifically to an electrical cabinet with a drying function. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials for protecting components to work properly. Inside, there are usually components such as power supplies, switches, power distribution, and circuit protection, which play an important role in the normal operation of the entire electrical system. It is widely used in many industries such as chemical industry, environmental protection, electric power, metallurgy, industry, nuclear power, fire safety monitoring, transportation, etc., as well as in the field of residential electricity use.

[0003] An electrical cabinet with a drying function, with the patent publication number CN210156757U, includes an electrical cabinet body and a base. The electrical cabinet body is divided into an upper cabinet body and a lower cabinet body by a metal plate. A heating box is arranged on one side of the metal plate close to the lower cabinet body. A fan is arranged in the upper cabinet body, and the air outlet of the fan passes through the metal plate and extends into the heating box. On the inner side of the middle part of the front panel of the lower cabinet body, a card slot is installed, and an observation window is arranged at the position of the front panel of the lower cabinet body corresponding to the card slot. A humidity detection device is placed in the card slot. In the electrical cabinet in the above application, a fan and a heating box are arranged, which can circulate and heat the air in the electrical cabinet, and discharge the moisture from the moisture discharge port, reducing the air humidity and preventing the electrical components in the electrical cabinet from being affected.

[0004] However, the above device dries by circulating and heating the air inside the electrical cabinet. If in a relatively cold environment, the hot air and cold air inside the electrical cabinet react, it is easier to form water vapor on the top of the inner wall of the electrical cabinet. When too much water vapor condenses on the top, it will form water droplets, and the larger water droplets are likely to drip on the electrical components, causing damage to the electrical components and thus triggering accidents. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electrical cabinet with a drying function, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: An electrical cabinet with a drying function includes an electrical cabinet housing. On the bottom surface of the inner wall of the electrical cabinet housing, electrical components are fixed. A drain opening is provided on the side wall of the electrical cabinet housing. A drain box is fixed to the inner wall of the electrical cabinet housing. A cabinet door is hinged to the front of the electrical cabinet housing. A handle is fixed to the front of the cabinet door. A warning sign is fixed to the front of the cabinet door. Heat dissipation holes are provided on the side wall of the electrical cabinet housing. A fixed rod is fixed to the inner wall of the electrical cabinet housing. The electrical cabinet housing is provided with a dehumidification mechanism for removing internal water vapor when it is colder, a protection mechanism for blocking rainwater in rainy and snowy weather, and a knocking mechanism for assisting drainage; wherein, the dehumidification mechanism includes a humidity sensor, a controller, a motor, a transmission component, a reciprocating lead screw, a slider, a first baffle, a hinge block, a sliding block, a first hinge rod, a second hinge rod, a pressing block, a third hinge rod, and a second baffle. The humidity sensor is fixedly installed on the upper surface of the electrical components. The controller is fixed on the upper surface of the electrical components. The humidity sensor and the controller are electrically connected.

[0007] According to the above technical solution, a placement groove is provided on the rear side surface of the inner wall of the electrical cabinet housing. The motor is fixedly installed on the bottom surface of the placement groove. The controller and the motor are electrically connected. The output end of the motor is fixedly connected to the end of the reciprocating lead screw. The bottom of the reciprocating lead screw is rotatably installed on the inner wall of the placement groove. There are two groups of reciprocating lead screws, and the two groups of reciprocating lead screws are symmetrically arranged with the center line in the vertical direction of the electrical cabinet housing as the axis of symmetry. The transmission component is arranged on the reciprocating lead screw.

[0008] According to the above technical solution, the transmission component includes a pulley and a belt. The pulley is fixed on the outer walls of the two groups of reciprocating lead screws, and a belt is wound around the two groups of pulleys. The reciprocating lead screw passes through the slider and is threadedly connected at the passing position. The fixed rod passes through the first baffle and is rotatably connected at the passing position. A first sliding groove is provided on the back surface of the first baffle. A roller is fixed to the front surface of the slider. The roller and the inner wall of the first sliding groove are slidably connected.

[0009] According to the above technical solution, a second sliding groove is formed on the front surface of the first baffle. The inner wall of the second sliding groove is slidably connected to the outer wall of the upper end of the hinge block. The bottom surface of the first baffle is slidably connected to the upper surface of the sliding block. The bottom end of the hinge block penetrates through the sliding block, and the penetration part is rotatably connected. A water-absorbing sponge is fixed to the side wall of the sliding block. The bottom surface of the sliding block is hinged to one end of the first hinge rod. The other end of the first hinge rod away from the sliding block is hinged to the upper surface of the electrical component. The humidity sensor is used to monitor the air humidity inside the electrical cabinet. In cooperation with the controller, the motor, the transmission component, the reciprocating lead screw and the slider, when the air humidity inside the electrical cabinet is relatively high, the first baffle is rotated and erected, so that the water vapor condensed on the bottom surface of the first baffle rolls down along the inclined surface. At the same time, the sliding block is pulled down through the first hinge rod, and the residual water vapor on the bottom surface of the first baffle is scraped off and absorbed by the water-absorbing sponge, avoiding excessive condensation of the water mist generated by the reaction of the hot air emitted during the operation of the electrical component and the cold air inside the electrical cabinet in colder weather, and preventing water droplets from dripping on the electrical component and damaging the electrical component.

[0010] According to the above technical solution, one end of the second hinge rod is hinged to the side surface of the inner wall of the electrical cabinet housing. The other end of the second hinge rod is hinged to the side surface of the extrusion block. The upper surface of the extrusion block is slidably connected to the bottom surface of the first baffle. The bottom surface of the extrusion block is hinged to the upper end of the third hinge rod. The lower end of the third hinge rod is hinged to the side wall of the second baffle. The upper end of the second baffle is hinged to the inner wall of the electrical cabinet housing.

[0011] According to the above technical solution, the protection mechanism includes a fourth hinge rod, a third baffle, saw teeth, a rotating rod and a scraping rod. One end of the fourth hinge rod is hinged to the upper surface of the first baffle. The other end of the fourth hinge rod is hinged to the side surface of the third baffle. The third baffle is slidably connected to the side surface of the inner wall of the electrical cabinet housing.

[0012] According to the above technical solution, a groove is formed on one side surface of the third baffle away from the fourth hinge rod. The saw teeth are fixedly installed on one side surface of the groove. A rotating rod penetrates through the side wall of the electrical cabinet housing. A gear is fixed to one side of the rotating rod. The gear meshes with the saw teeth. The other side of the rotating rod is fixedly connected to the side wall of the scraping rod.

[0013] According to the above technical solution, the knocking mechanism includes a guide rod, a connecting plate, a spring and a knocking plate. The guide rod is fixedly installed on the outer wall of the electrical cabinet housing. The guide rod penetrates through the connecting plate, and the penetration part is slidably connected.

[0014] According to the above technical solution, one end of the spring is fixedly connected to the side wall of the connecting plate, and the other end of the spring is fixedly connected to the outer wall of the electrical cabinet housing. A knocking plate is fixed on the side wall of the connecting plate. The knocking plate is pushed to move outwards by the rotation of the scraping rod. At the same time, in cooperation with the guide rod, the connecting plate and the spring, when the scraping rod continues to rotate, the knocking plate is driven to move towards the electrical cabinet to knock the electrical cabinet, so that the water in the drainage tank slides down along the inner wall of the drainage tank more smoothly, reducing the water adhering to the inner wall of the drainage tank and increasing the drainage efficiency of the drainage port.

[0015] The present invention provides an electrical cabinet with a drying function, having the following beneficial effects:

[0016] (1) In the present invention, the humidity sensor monitors the air humidity inside the electrical cabinet. In cooperation with the controller, the motor, the transmission assembly, the reciprocating lead screw and the slider, when the air humidity inside the electrical cabinet is relatively high, the first baffle is rotated and erected, so that the water vapor condensed on the bottom surface of the first baffle rolls down along the inclined surface. At the same time, the sliding block is pulled downwards by the first hinge rod to scrape off the remaining water vapor on the bottom surface of the first baffle, which is absorbed by the water-absorbing sponge, avoiding excessive condensation of the water mist generated by the reaction of the hot air emitted by the electrical components with the cold air during operation in cold weather, and preventing water droplets from forming and dropping on the electrical components, damaging the electrical components. When the first baffle rotates, the second hinge rod pushes the extrusion block to slide upwards, reducing the distance between the extrusion block and the sliding block, squeezing the water-absorbing sponge, and squeezing out the water absorbed by the water-absorbing sponge into the drainage tank. The extrusion block cooperates with the third hinge rod to drive the second baffle to open, exposing the drainage port, so that the water inside the electrical cabinet can be better drained, avoiding the re-evaporation and circulation of the squeezed water inside the electrical cabinet and failing to achieve the effect of reducing the air humidity for drying.

[0017] (2) In the present invention, the rotation of the first baffle drives the rotation of the fourth hinge rod, pushing the third baffle to slide upwards to block the heat dissipation holes, avoiding rainwater from easily entering through the heat dissipation holes when the external environment is rainy or snowy during dehumidification. At the same time, when the third baffle rises, in cooperation with the linkage of the saw teeth and the gear, the rotating rod and the scraping rod are driven to rotate, scraping the rainwater around the heat dissipation holes outside the electrical cabinet, avoiding rainwater from flowing into the electrical cabinet through the gaps and affecting the dehumidification and drying effect of the dehumidification mechanism.

[0018] (3) In the present invention, the rotation of the scraping rod pushes the knocking plate to move outwards. At the same time, in cooperation with the guide rod, the connecting plate and the spring, when the scraping rod continues to rotate, the knocking plate is driven to move towards the electrical cabinet to knock the electrical cabinet, so that the water in the drainage tank slides down along the inner wall of the drainage tank more smoothly, reducing the water adhering to the inner wall of the drainage tank and increasing the drainage efficiency of the drainage port.

[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 1-7 , an embodiment of the present invention is: An electrical cabinet with a drying function, including an electrical cabinet housing 1, an electrical component is fixed on the bottom surface of the inner wall of the electrical cabinet housing 1, a drain port is provided on the side wall of the electrical cabinet housing 1, a drain box is fixed on the inner wall of the electrical cabinet housing 1, a cabinet door 2 is hinged on the front of the electrical cabinet housing 1, a handle is fixed on the front of the cabinet door 2, a warning sign is fixed on the front of the cabinet door 2, a heat dissipation hole 3 is provided on the side wall of the electrical cabinet housing 1, a fixed rod 4 is fixed on the inner wall of the electrical cabinet housing 1, and the electrical cabinet housing 1 is provided with a dehumidification mechanism 5 for removing internal water vapor when it is colder.

[0029] Among them, the dehumidification mechanism 5 includes a humidity sensor 51, a controller 52, a motor 53, a transmission component 54, a reciprocating lead screw 55, a slider 56, a first baffle 57, a hinge block 58, a sliding block 59, a first hinge rod 510, a second hinge rod 511, a pressing block 512, a third hinge rod 513 and a second baffle 514. The humidity sensor 51 is fixedly installed on the upper surface of the electrical component, and the controller 52 is fixed on the upper surface of the electrical component. There is an electrical connection between the humidity sensor 51 and the controller 52. When the humidity sensor 51 detects that the air humidity inside the electrical cabinet is relatively high, it transmits a signal to the adjacent controller 52. A placement groove is provided on the rear side of the inner wall of the electrical cabinet housing 1. The motor 53 is fixedly installed on the bottom surface of the placement groove. There is an electrical connection between the controller 52 and the motor 53. After receiving the signal, the controller 52 controls the motor 53 to start. The output end of the motor 53 is fixedly connected to the end of the reciprocating lead screw 55. The bottom of the reciprocating lead screw 55 is rotatably installed on the inner wall of the placement groove. There are two groups of reciprocating lead screws 55, and the two groups of reciprocating lead screws 55 are symmetrically arranged with the center line of the electrical cabinet housing 1 in the vertical direction as the axis of symmetry. The transmission component 54 is arranged on the reciprocating lead screw 55. The transmission component 54 includes a pulley and a belt. The pulley is fixed on the outer walls of the two groups of reciprocating lead screws 55, and a belt is wound around the two groups of pulleys. When the motor 53 starts, its output end drives the pulley at one end of the transmission component 54 to rotate. When the pulley rotates, it drives the pulley at the other end to rotate through the belt. When the pulleys at both ends rotate, they drive the reciprocating lead screws 55 at both ends to rotate respectively. The reciprocating lead screw 55 passes through the slider 56 and is threadedly connected at the passing point. Since the inner wall of the slider 56 is threadedly connected to it, when the reciprocating lead screw 55 rotates, it drives the slider 56 to slide upward. And because the motor 53 continues to rotate, when the slider 56 slides to the uppermost end, it changes to slide downward along the thread groove of the reciprocating lead screw 55, and slides upward along the thread groove again when it slides to the lowermost end until the humidity sensor 51 detects that the humidity has dropped to the normal value and sends a signal to the controller 52 to stop the motor 53. The fixed rod 4 passes through the first baffle 57 and is rotatably connected at the passing point. A first sliding groove is provided on the back surface of the first baffle 57. A roller is fixed on the front surface of the slider 56. When the slider 56 slides upward, it drives the roller to move upward. The roller is slidably connected to the inner wall of the first sliding groove. Therefore, when the slider 56 slides upward, it drives the first baffle 57 to rotate around the fixed rod 4, causing the end of the first baffle 57 close to the center of the electrical cabinet to tilt upward. A second sliding groove is provided on the front surface of the first baffle 57. The inner wall of the second sliding groove is slidably connected to the outer wall of the upper end of the hinge block 58. The bottom surface of the first baffle 57 is slidably connected to the upper surface of the sliding block 59. The bottom end of the hinge block 58 passes through the sliding block 59 and is rotatably connected at the passing point. A water-absorbing sponge is fixed on the side wall of the sliding block 59. When the sliding block 59 slides downward along the bottom surface of the first baffle 57, it can scrape off the water vapor on the bottom surface of the first baffle 57, and at the same time, the water-absorbing sponge on the side wall of the sliding block 59 absorbs the condensed water vapor. The bottom surface of the sliding block 59 is hinged to the first hinge rod 510.One end of the first hinge rod 510 away from the sliding block 59 is hinged to the upper surface of the electrical component. When one end of the first baffle 57 close to the center tilts up, the distance between the sliding block 59 and the electrical component becomes larger, driving the first hinge rod 510 to rotate. The rotation of the first hinge rod 510 drives the sliding block 59 to slide downward along the bottom surface of the first baffle 57. One side of the inner wall of the electrical cabinet housing 1 is hinged to one end of the second hinge rod 511, and the other end of the second hinge rod 511 is hinged to the side surface of the extrusion block 512. The upper surface of the extrusion block 512 is slidably connected to the bottom surface of the first baffle 57. Since the extrusion block 512 is hinged to the side wall of the electrical cabinet housing 1 through the second hinge rod 511, when one end of the first baffle 57 away from the center descends, the distance between the extrusion block 512 and the side wall of the electrical cabinet housing 1 becomes larger, driving the second hinge rod 511 to rotate. The rotation of the second hinge rod 511 pushes the extrusion block 512 to slide upward, and the extrusion block 512 approaches the sliding block 59, squeezing out the excess water in the water-absorbing sponge. The bottom surface of the extrusion block 512 is hinged to the upper end of the third hinge rod 513, and the lower end of the third hinge rod 513 is hinged to the side wall of the second baffle 514. The upper end of the second baffle 514 is hinged to the inner wall of the electrical cabinet housing 1. Since the extrusion block 512 and the second baffle 514 are hinged through the third hinge rod 513, and at the same time the upper end of the second baffle 514 is hinged to the side wall of the electrical cabinet housing 1, when the extrusion block 512 slides upward, the distance between the extrusion block 512 and the second baffle 514 becomes larger, driving the third hinge rod 513 to rotate. The rotation of the third hinge rod 513 drives the second baffle 514 to rotate and open around the hinge point between the second baffle 514 and the electrical cabinet housing 1, exposing the drain outlet. The water squeezed out by the water-absorbing sponge falls into the drainage tank and flows out through the drain port. The dehumidification mechanism 5 monitors the humidity of the air inside the electrical cabinet through the humidity sensor 51, and cooperates with the controller 52, the motor 53, the transmission assembly 54, the reciprocating lead screw 55 and the slider 56 to rotate the first baffle 57 upright when the humidity of the air inside the electrical cabinet is relatively high, so that the water vapor condensed on the bottom surface of the first baffle 57 rolls down along the inclined surface. At the same time, the sliding block 59 is pulled downward through the first hinge rod 510, scraping off the residual water vapor on the bottom surface of the first baffle 57 and absorbing it through the water-absorbing sponge, avoiding excessive condensation of the water mist generated by the reaction of the hot air emitted during the operation of the electrical component with the cold air inside the electrical cabinet in cold weather, and preventing water droplets from forming and damaging the electrical component; when the first baffle 57 rotates, the extrusion block 512 is pushed upward through the second hinge rod 511, reducing the distance between the extrusion block 512 and the sliding block 59, squeezing the water-absorbing sponge, squeezing out the water absorbed by the water-absorbing sponge into the drainage tank, and driving the second baffle 514 to open through the cooperation of the extrusion block 512 and the third hinge rod 513, exposing the drain port, so that the moisture inside the electrical cabinet can be better discharged, avoiding the re-evaporation and circulation of the squeezed-out water inside the electrical cabinet and failing to achieve the effect of reducing the air humidity and drying.,

[0030] During the operation of this embodiment: When the humidity sensor 51 detects that the air humidity inside the electrical cabinet is relatively high, it transmits a signal to the adjacent controller 52. The controller 52 controls the motor 53 to start. When the motor 53 starts, the pulley at one end of the transmission assembly 54 is driven to rotate at its output end. When the pulley rotates, it drives the pulley at the other end to rotate through the belt. When the pulleys at both ends rotate, they respectively drive the reciprocating lead screws 55 at both ends to rotate. Since the inner wall of the slider 56 is threadedly connected thereto, the reciprocating lead screw 55 drives the slider 56 to slide upward when it rotates. When the slider 56 slides upward, it drives one end of the first baffle 57 to move upward. The other end of the first baffle 57 is rotatably connected to the fixed rod 4, and the roller on the front surface of the slider 56 is slidably connected to the first sliding groove on the side wall of the first baffle 57. Therefore, when the slider 56 slides upward, it drives the first baffle 57 to rotate around the fixed rod 4, causing the end of the first baffle 57 close to the center of the electrical cabinet to tilt up. Since the sliding block 59 is hinged to the electrical component through the first hinge rod 510, when the end of the first baffle 57 close to the center tilts up, the distance between the sliding block 59 and the electrical component becomes larger, driving the first hinge rod 510 to rotate. The rotation of the first hinge rod 510 drives the sliding block 59 to slide downward along the bottom surface of the first baffle 57, scraping off the water vapor on the bottom surface of the first baffle 57. At the same time, the water-absorbing sponge on the side wall of the sliding block 59 absorbs the condensed water vapor. When the first baffle 57 rotates, the end away from the center of the electrical cabinet moves downward. Since the extrusion block 512 is hinged to the side wall of the electrical cabinet housing 1 through the second hinge rod 511, when the end of the first baffle 57 away from the center descends, the distance between the extrusion block 512 and the side wall of the electrical cabinet housing 1 becomes larger, driving the second hinge rod 511 to rotate. The rotation of the second hinge rod 511 pushes the extrusion block 512 to slide upward. The extrusion block 512 approaches the sliding block 59, squeezing out the excess water in the water-absorbing sponge. Since the extrusion block 512 and the second baffle 514 are hinged through the third hinge rod 513, and at the same time the upper end of the second baffle 514 is hinged to the side wall of the electrical cabinet housing 1, when the extrusion block 512 slides upward, the distance between the extrusion block 512 and the second baffle 514 becomes larger, driving the third hinge rod 513 to rotate. The rotation of the third hinge rod 513 drives the second baffle 514 to rotate and open around the hinge point of the second baffle 514 and the electrical cabinet housing 1, exposing the discharge port. The water squeezed out from the water-absorbing sponge falls into the drainage box and flows out through the drain port.

[0031] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a protection mechanism 6 for blocking rainwater in rainy and snowy weather is provided on the electrical cabinet housing 1. The protection mechanism 6 includes a fourth hinge rod 61, a third baffle 62, a sawtooth 63, a rotating rod 64, and a scraping rod 65. One end of the fourth hinge rod 61 is hinged to the upper surface of the first baffle 57, and the other end of the fourth hinge rod 61 is hinged to the side surface of the third baffle 62. The third baffle 62 is slidably connected to the side surface of the inner wall of the electrical cabinet housing 1. Since the first baffle 57 and the third baffle 62 are hinged by the fourth hinge rod 61, when one end of the first baffle 57 close to the center of the electrical cabinet tilts up, the distance between the first baffle 57 and the third baffle 62 becomes smaller, driving the fourth hinge rod 61 to rotate. The rotation of the fourth hinge rod 61 pushes the third baffle 62 to slide upward to block the heat dissipation holes 3. A groove is formed on one side surface of the third baffle 62 away from the fourth hinge rod 61, and the sawtooth 63 is fixedly installed on one side surface of the groove. When the third baffle 62 slides upward, the sawtooth 63 moves upward with the third baffle 62. A rotating rod 64 penetrates through the side wall of the electrical cabinet housing 1. A gear is fixed on one side of the rotating rod 64, and the gear meshes with the sawtooth 63. When the sawtooth 63 moves upward, it drives the gear to rotate. The other side of the rotating rod 64 is fixedly connected to the side wall of the scraping rod 65. When the gear rotates, the scraping rod 65 is driven to rotate through the rotating rod 64 to scrape off the rainwater on the part of the outer wall of the electrical cabinet close to the heat dissipation holes 3. The protection mechanism 6 drives the fourth hinge rod 61 to rotate by the rotation of the first baffle 57, and pushes the third baffle 62 to slide upward to block the heat dissipation holes 3, avoiding that in the process of dehumidification, when the external environment is rainy and snowy weather, rainwater is easily swept into the electrical cabinet from the heat dissipation holes 3, and when the first baffle 57 is erected, it cannot block above the electrical components, resulting in rainwater falling on the electrical components and causing damage to the electrical components; at the same time when the third baffle 62 rises, in cooperation with the linkage of the sawtooth 63 and the gear, the rotating rod 64 and the scraping rod 65 are driven to rotate, and the rainwater around the heat dissipation holes 3 is scraped off outside the electrical cabinet, avoiding rainwater flowing into the interior of the electrical cabinet from the gap and affecting the dehumidification and drying effect of the dehumidification mechanism 5.

[0032] The electrical cabinet housing 1 is provided with a knocking mechanism 7 for auxiliary drainage. The knocking mechanism 7 includes a guide rod 71, a connecting plate 72, a spring 73 and a knocking plate 74. The guide rod 71 is fixedly installed on the outer wall of the electrical cabinet housing 1. The guide rod 71 penetrates through the connecting plate 72 and is slidably connected at the penetration point. One side wall of the connecting plate 72 is fixedly connected to one end of the spring 73, and the other end of the spring 73 is fixedly connected to the outer wall of the electrical cabinet housing 1. When the connecting plate 72 slides away from the electrical cabinet housing 1, the spring 73 is stretched. A knocking plate 74 is fixed to the side wall of the connecting plate 72. When the scraping rod 65 rotates, when the scraping rod 65 rotates to contact the knocking plate 74, the scraping rod 65 pushes the knocking plate 74 to slide along the inclined surface away from the electrical cabinet housing 1. When the scraping rod 65 rotates away from the knocking plate 74, the connecting plate 72 is driven by the restoring elastic force of the spring 73 to drive the knocking plate 74 to slide towards the electrical cabinet housing 1, so that the knocking plate 74 knocks on the electrical cabinet housing 1. This knocking mechanism 7 pushes the knocking plate 74 to move outwards through the rotation of the scraping rod 65, and at the same time cooperates with the guide rod 71, the connecting plate 72 and the spring 73. When the scraping rod 65 continues to rotate, it drives the knocking plate 74 to move towards the electrical cabinet and knocks on the electrical cabinet, making the water in the drainage box slide down more smoothly along the inner wall of the drainage box, reducing the water adhering to the inner wall of the drainage box, and increasing the drainage efficiency of the drainage port.

[0033] When this embodiment works: Since the first baffle 57 and the third baffle 62 are hinged by the fourth hinge rod 61, when one end of the first baffle 57 close to the center of the electrical cabinet tilts up, the distance between the first baffle 57 and the third baffle 62 becomes smaller, driving the fourth hinge rod 61 to rotate. The fourth hinge rod 61 rotates and pushes the third baffle 62 to slide upwards, blocking the heat dissipation hole 3. When the third baffle 62 slides upwards, the serrations 63 on the side away from the fourth hinge rod 61 move upwards along with the third baffle 62, driving the gear meshed with it to rotate. When the gear rotates, it drives the scraping rod 65 to rotate through the rotating rod 64, scraping off the rainwater on the part of the outer wall of the electrical cabinet close to the heat dissipation hole 3.

[0034] When the scraping rod 65 rotates, when the scraping rod 65 rotates to contact the knocking plate 74, the scraping rod 65 pushes the knocking plate 74 to slide along the inclined surface away from the electrical cabinet housing 1. The knocking plate 74 is fixedly connected to the connecting plate 72, and the connecting plate 72 is penetrated by the guide rod 71. Therefore, the knocking plate 74 and the connecting plate 72 slide along the guide rod 71 away from the electrical cabinet housing 1 together. When the connecting plate 72 slides away from the electrical cabinet housing 1, the spring 73 is stretched. The scraping rod 65 continues to rotate. When the scraping rod 65 rotates away from the knocking plate 74, the connecting plate 72 is driven by the restoring elastic force of the spring 73 to drive the knocking plate 74 to slide towards the electrical cabinet housing 1, so that the knocking plate 74 knocks on the electrical cabinet housing 1.
