Abstract
Description
Technical Field
[0001] The invention relates to the field of power distribution cabinets, and in particular to a rainproof and lightning-proof power distribution cabinet. Background Art
[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.
[0003] The existing rain and lightning protection structure of the power distribution cabinet has the following deficiencies:
[0004] 1. Since the top of the cabinet is generally a horizontal structure, when it rains, the cabinet top plate is subject to the greatest impact of rainwater, which can easily cause corrosion to the cabinet top plate over a long period of time, reducing the service life of the cabinet.
[0005] 2. Although a lightning rod is designed, it is generally designed to be on the outside of the cabinet and is exposed. The surface of the lightning rod is easily worn out by exposure to the sun and wind, which reduces its service life and undoubtedly increases the cost of lightning protection.
[0006] 3. The existing distribution cabinet cannot automatically add desiccant in time according to weather conditions. When it rains, it is not convenient to automatically remove moisture from the distribution cabinet. The internal distribution equipment is prone to malfunction due to moisture, causing losses.

[0023] Beneficial effects of the present invention:
[0024] 1. The present invention designs a lightning sensor and a rainproof mechanism, namely a driving component, a telescopic component and two rain shields. The lightning sensor detects lightning conditions. When thunder is detected, a signal is sent to a controller, thereby starting the driving component through the controller. The telescopic component is driven by the driving component to drive the two rain shields to move closer to each other until they are tightly closed. The top of the cabinet can be covered and protected before rainfall, reducing the direct impact of rain on the top of the cabinet, thereby avoiding corrosion of the cabinet top plate caused by long-term impact of rain, which is beneficial to extending the service life of the cabinet and improving the maintenance efficiency of the distribution cabinet.
[0025] 2. The present invention realizes the linkage operation of the rain protection mechanism and the lightning protection mechanism by designing a traction component, that is, when the two rain shields are close to each other and closed to protect against rain, the lightning rod is driven to extend from the inside of the cabinet to the outside of the cabinet, and the positive charge on the cloud layer is introduced into the earth through the grounding component to form a downward current, neutralizing the potential difference between the cloud layer and the earth, so that the air will not be broken down due to the potential difference to discharge to the distribution cabinet, thereby achieving the lightning protection effect.
[0026] 3. The present invention designs the lightning rod into a retractable structure. When in use, it extends from the inside of the cabinet, and when not in use, it is retracted inside the cabinet. This can prevent the existing lightning rod from being worn out by long-term exposure to the sun and wind due to being installed outside the cabinet, thereby reducing its service life, thereby helping to reduce the cost of lightning protection.
[0027] 4. The present invention realizes the linkage operation of the rainproof mechanism and the spreading mechanism by designing a transmission component, that is, when the two rain shields are close to each other and closed to prevent rain, the silica gel desiccant can be evenly spread inside the cabinet at the same time. While spreading the silica gel desiccant, the two electric slides are started, so that the tray is driven to rise by the two sliders until it rises to the bottom of the spreading tray and keeps a close distance from the spreading tray, so that the spread silica gel desiccant can accurately fall into the interior of several storage tanks, and the desiccant will not be broken or splashed to the outside of the tray due to the high spreading height, which is convenient for the replacement of the desiccant after failure in the later stage. When the silica gel desiccant is sprinkled on several storage tanks, the tray is driven to descend to the inner bottom of the cabinet by the two sliders on the two electric slides, which can avoid affecting the power distribution equipment. At the same time, it is convenient to absorb the moisture inside the cabinet through the silica gel desiccant to achieve a moisture-proof effect. It should be noted that the silica gel desiccant will change color after absorbing moisture. The darker the color becomes compared with the initial state, the more moisture is absorbed. Subsequent replacement can be distinguished according to the depth of color.
[0028] 5. The present invention can realize automatic winding and unwinding of the wire by designing the second rack, the second gear, the second guide wheel and the first reset spring, so that the wire can automatically adjust the guide length according to the extension and retraction of the lightning rod. On the one hand, it can prevent the wire from being torn, and on the other hand, it can prevent the wire from drooping inside the cabinet and entangled with the first pull rope, thereby avoiding affecting the grounding operation of the lightning rod, which is beneficial to improving the lightning protection effect.
[0029] 6. The present invention can realize the linkage operation of the rainproof mechanism and the lightning protection mechanism as well as the linkage operation of the rainproof mechanism and the spreading mechanism by designing the traction component and the transmission component. When lightning is detected, the two rain shields are brought close to each other to realize rain protection, and the lightning rod is simultaneously extended from the inside of the cabinet to realize lightning protection. While preventing rain, silica gel desiccant can be synchronously sprinkled inside the cabinet to ensure that the moisture generated during rainfall can be absorbed by the desiccant in time, which not only realizes external rain protection but also internal moisture protection, further enhances the protection of the power distribution equipment inside the cabinet, and avoids losses caused by circuit failures. At the same time, multiple sets of linkage are realized only by a single driving source, that is, the electric push rod, which greatly reduces the overall power consumption of the distribution cabinet and reduces the cost of rain and lightning protection. At the same time, it can effectively reduce the overall structure of the rainproof mechanism, the lightning protection mechanism and the spreading mechanism, reduce the cost and the space occupied by the distribution cabinet, facilitate installation, and improve practicality.
[0030] 7. The present invention separates the rain protection mechanism, lightning protection mechanism and spreading mechanism from the power distribution equipment in the cabinet by designing a partition. At the same time, by arranging the tray at the inner bottom of the cabinet, that is, the tray is initially located at the inner bottom of the cabinet, it can prevent interference with the power distribution equipment and will not affect the normal operation of the distribution cabinet.

[0048] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.
[0049] Reference Figures 1 to 13 As shown, a rainproof and lightning-proof power distribution cabinet comprises a base 1 and a cabinet body 2, wherein a power distribution device 20 is arranged inside the cabinet body 2, and the cabinet body 2 is fixedly arranged on the top of the base 1;

[0053] The spreading mechanism 5 is arranged inside the cabinet 2, and the spreading mechanism 5 includes a tray 50, a scattering tray 51, a hopper 52, a transmission assembly 53 and a pushing assembly 54. The scattering tray 51 is fixedly arranged below the partition 21, and the tray 50 is movably arranged inside the cabinet 2. A plurality of discharge holes 520 are evenly spaced at the bottom of the hopper 52, and a slide groove 415 is integrally formed on the top of the tray. The hopper 52 is slidably arranged inside the slide groove 415, and a plurality of spreading holes 510 are evenly spaced inside the slide groove 415, and each discharge hole 520 is consistent with the diameter of a spreading hole 510. The pushing assembly 54 is arranged on the partition 21, and the transmission assembly 53 is arranged between the pushing assembly 54 and another rain shield 32, and the driving assembly 30 is electrically connected to the controller.
[0054] Reference Figures 1 to 13As shown, the driving assembly 30 includes an electric push rod 300, a first rack 301 and a first gear 302. The electric push rod 300 is fixedly arranged on the outer wall of the cabinet 2. Two L-shaped rods are symmetrically arranged on the same outer wall of the cabinet 2. Two first hinge shafts are rotatably arranged on the outer wall of each L-shaped rod. The first gear 302 is fixedly arranged on one of the first hinge shafts. The first rack 301 is slidably arranged on the outer wall of the cabinet 2 through a first slide rail. The first gear 302 and the first rack 301 are meshed and connected. The output end of the electric push rod 300 is connected to the first rack 301. 01 is fixedly connected to the bottom, and the electric push rod 300 is electrically connected to the controller. When the controller receives the lightning signal, the electric push rod 300 is started by the controller, so that its output end extends upward. Since its output end is fixedly connected to the first rack 301, the first rack 301 is slidably connected to the first slide rail, the first gear 302 is meshed with the first rack 301, and the first gear 302 is fixedly connected to one of the first hinge shafts, so that the first rack 301 slides up in the first slide rail and drives one of the first hinge shafts to rotate counterclockwise.
[0055] Reference Figures 1 to 13 As shown, the telescopic assembly 31 includes two bevel teeth 310, two first connecting rods 311 and two second connecting rods 312, the two first connecting rods 311 and the two second connecting rods 312 are respectively fixedly arranged on the four first hinge shafts, the two bevel teeth 310 are respectively fixedly connected to one end of one of the first connecting rods 311 and one of the second connecting rods 312, and one end of each first connecting rod 311 and each second connecting rod 312 away from the bevel teeth 310 is hinged to the side wall of one of the rain shields 32, and the two bevel teeth 310 are meshed and connected. When one of the first hinge shafts rotates counterclockwise, due to the meshing connection of the two bevel teeth 310, the two first connecting rods 311 and the two second connecting rods 312 are respectively fixedly connected to the four first hinge shafts, and the two bevel teeth 310 are respectively connected to the side wall of the rain shield 32. One end of a first connecting rod 311 and one end of a second connecting rod 312 are fixedly connected, and one end of each first connecting rod 311 and each second connecting rod 312 away from the umbrella tooth 310 is hinged to the side wall of one of the rain shields 32, and then the two first connecting rods 311 and the two second connecting rods 312 drive the two rain shields 32 to approach each other until they are closed. It should be noted that the model drawn in this application is a state of completed action. In the initial state, the two rain shields 32 are far away from each other, and the lightning rod 40 is also stored inside the cabinet 2. Only when thunderstorm weather is detected, the two rain shields 32 need to approach each other until they are closed to shield the top of the cabinet 2 from rain. The synchronous belt 540 drives the lightning rod 40 to extend from the inside of the cabinet 2 to perform lightning protection operations.
[0056] Reference Figures 1 to 13As shown, the traction assembly 41 includes a first pull rope 410, a lifting plate 411, two telescopic springs 412 and a plurality of first guide wheels 413. The lifting plate 411 is slidably arranged on the outer walls of the two guide rods 210. Each telescopic spring 412 is sleeved on the outer wall of a guide rod 210. The bottom end of the lifting plate 411 and the top of each support rod are in contact with the two ends of a telescopic spring 412. The first pull rope 410 is fixedly arranged between the bottom of the lifting plate 411 and the bottom of one of the rain shields 32. The first guide wheel 413 is rotatably arranged on the cabinet 2 and one of the support rods, respectively. The outer wall of the first pull rope 410 is fitted with the outer edges of the first guide wheels 413. The top of the cabinet 2 is provided with a through groove for the lifting plate 411 to pass through. Two slide plates 414 are fixedly arranged at the bottom of each rain shield 32. Four slide grooves 415 are symmetrically arranged on the top of the cabinet 2. Each slide plate 414 is slidably connected to a slide groove 415. The two side walls of the cabinet 2 are symmetrically provided with first guide rails for the four slide plates 414 to slide. 22. Since the two telescopic springs 412 are initially contracted, the first pull rope 410 is in a taut state. When the two rain shields 32 initially approach each other, the first pull rope 410 is in a short-term relaxed state, so that the two telescopic springs 412 are transformed from a contracted state to a stretched state. Since one end of the bottom of the lifting plate 411 and the top of each support rod are in contact with the two ends of a telescopic spring 412, the bottom of the lifting plate 411 and the bottom of one of the rain shields 32 are respectively fixedly connected to the two ends of the first pull rope 410. Then, the lifting plate 411 slides upward synchronously on the outer walls of the two guide rods 210 until the lightning rod 40 on the top of the lifting plate 411 extends out from the semicircular through hole 320 between the two rain shields 32 when the two rain shields 32 are closed, in preparation for lightning protection. It should be noted here that the lightning rod 40 is designed as a retractable structure, that is, it is initially located inside the cabinet 2, which can avoid the existing lightning rod 40 from being worn out by long-term exposure to the sun and wind due to being installed outside the cabinet 2, thereby reducing its service life and thus reducing the cost of lightning protection.
[0057] Reference Figures 1 to 13As shown, the grounding assembly 42 includes a wire 420, a winding drum 421, a grounding block 422, a second rack 423, a second gear 424, a second guide wheel 425 and a first reset spring 426. The winding drum 421 is rotatably arranged on the outer wall of the cabinet 2 through a second hinge shaft, the wire 420 is fixedly arranged at the bottom end of the lightning rod 40, the wire 420 is wound and connected with the winding drum 421, and is guided through the cabinet 2. The second guide wheel 425 is rotatably arranged on the outer wall of one of the support rods, and the outer wall of the wire 420 is in contact with the outer edge of the second guide wheel 425. The grounding block 422 is fixedly arranged at the end of the wire 420 away from the lightning rod 40, and the second rack 423 slides through the second slide rail. The second gear 424 is fixed on the outer wall of the cabinet 2, and the second gear 424 is meshed with the second rack 423. The first return spring 426 is fixed between the bottom of the second rack 423 and the inner wall of the second slide rail. In thunderstorm weather, the charged cloud layer in the air gathers a large amount of charge on the tip of the lightning rod 40 due to the electrostatic induction effect. When the charge on the cloud layer is large, the air between the lightning rod 40 and the cloud layer is easily broken down and becomes a conductor. In this way, the charged cloud layer and the lightning rod 40 form a passage. Since the bottom end of the lightning rod 40 is electrically connected to the grounding block 422 through the wire 420, the lightning rod 40 can pass the charge on the cloud layer through the grounding block 422. The positive charge is introduced into the earth to form a downward current, neutralizing the potential difference between the cloud layer and the earth, so that the potential difference will not break through the air and discharge to the distribution cabinet, thereby achieving a lightning protection effect. When the lifting plate 411 rises, the wire 420 is fixedly connected to the lightning rod 40 on the lifting plate 411, so that the wire 420 is automatically unwound on the winding drum 421 and rises synchronously with the lightning rod 40, that is, the winding drum 421 unwinds the wire counterclockwise, thereby driving the second gear 424 coaxial with the winding drum 421 to rotate counterclockwise. Since the second gear 424 is meshed and connected with the second rack 423, and the second rack 423 is slidably connected with the second slide rail, the second rack 423 is driven. Slide up inside the second slide rail. Since the bottom of the second rack 423 and the inner wall of the second slide rail are respectively fixedly connected to the two ends of the first return spring 426, the first return spring 426 is transformed from the initial state to the stretched state. Every time the lifting block drives the lightning rod 40 to retract into the cabinet 2, the second rack 423 driven by the first return spring 426 slides down, thereby driving the second gear 424 to rotate clockwise, thereby driving the winding reel 421 to reel the wire 420 clockwise, thereby realizing the resetting of the wire 420. At the same time, it can prevent the wire 420 from drooping inside the cabinet 2 and entangled with the first pull rope 410, so as to avoid affecting the grounding operation of the lightning rod 40.
[0058] Reference Figures 1 to 13As shown, the transmission assembly 53 includes a second pull rope 530, a third rack 531, a third gear 532, a second return spring 533 and two third guide wheels 534. The second guide rail 23 is fixedly arranged on the top of the partition 21. The third rack 531 is slidably arranged on the second guide rail 23. The second pull rope 530 is fixedly arranged between another rain shield 32 and one end of the third rack 531. The second return spring 533 is fixedly arranged between the other end of the third rack 531 and the inner wall of the second guide rail 23. Two third hinge shafts are rotatably arranged on the top of the partition 21. The third gear 532 is fixedly arranged on the top of one of the third hinge shafts. The third rack 531 is meshed with the third gear 532. The two third guide wheels 534 are rotatably arranged on the outer wall of the cabinet 2 through a T-plate. The outer wall of the second pull rope 530 is connected to the two third guide wheels 534. The outer edges of the two rain shields 32 are in contact with each other, that is, when the lightning rod 40 is extended, since the other rain shield 32 and one end of the third rack 531 are respectively fixedly connected to the two ends of the second pull rope 530, the third rack 531 is slidably connected to the second guide rail 23, thereby driving the third rack 531 to slide inside the second guide rail 23 toward the end close to the third guide wheel 534. Since the third gear 532 is fixedly connected to the top end of one of the third hinge shafts, the third rack 531 is meshed with the third gear 532, thereby driving one of the third hinge shafts close to the conductor 420 to rotate clockwise. At the same time, since the other end of the third rack 531 and the inner wall of the second guide rail 23 are respectively fixedly connected to the two ends of the second reset spring sliding, the second reset spring 533 is driven to change from the initial state to the stretched state.
[0059] Reference Figures 1 to 13As shown, the pushing assembly 54 includes a synchronous belt 540, a swing rod 541, a push rod 542 and two synchronous wheels 543. The two synchronous wheels 543 are respectively fixed on two third hinge shafts. The synchronous belt 540 is sleeved between the two synchronous wheels 543. The swing rod 541 is fixed at the bottom end of one of the third hinge shafts away from the third gear 532. The push rod 542 is hinged at one end of the swing rod 541 away from the third hinge shaft. The end of the push rod 542 away from the swing rod 541 is hinged to the hopper 52. When one of the third hinge shafts close to the wire 420 rotates clockwise, since the two synchronous wheels 543 are respectively fixedly connected to the two third hinge shafts, the two synchronous wheels 543 are sleeved through the synchronous belt 540, and the swing rod 541 is connected to one of the third hinge shafts. The third hinge shaft away from the third gear 532 is fixedly connected, one end of the rocker arm 541 away from the third hinge shaft and the hopper 52 are hinged to the two ends of the top rod 542 respectively, the hopper 52 is slidably connected to the scattering plate 51, thereby driving the hopper 52 to slide from left to right inside the scattering plate 51, silica gel desiccant is stored inside the hopper 52, a row of discharge holes 520 are designed at the bottom of the hopper 52, and a plurality of rows of throwing holes 510 are designed at equal intervals inside the scattering plate 51. Since each discharge hole 520 is consistent with the diameter of a throwing hole 510, when the hopper 52 slides from left to right inside the scattering plate 51, each time a row of discharge holes 520 coincides with a row of throwing holes 510, the silica gel desiccant is thrown once.
[0060] Reference Figures 1 to 13 As shown, a plurality of storage slots 500 are arranged at equal intervals on the top of the tray 50, and two electric slides 24 are symmetrically arranged on the inner wall of the lower half of the cabinet 2, each electric slide 24 is provided with a slider 25, and the two ends of the tray 50 are respectively fixedly connected to the outer walls of the two sliders 25. While sprinkling the silica gel desiccant, the two electric slides 24 are started, thereby driving the tray 50 to rise through the two sliders 25 until it rises to the bottom of the scattering plate 51, and keeps a close distance from the scattering plate 51, so that the scattered silica gel desiccant can accurately fall into the interior of the plurality of storage slots 500, and will not be scattered due to the sprinkling. Too high a height may cause the desiccant to break or splash to the outside of the tray 50, which makes it easier to replace the desiccant after it becomes ineffective. When several storage tanks 500 are spilled onto the silica gel desiccant, the two sliders 25 on the two electric slides 24 drive the tray 50 down to the inner bottom of the cabinet 2, which can avoid affecting the power distribution equipment 20. At the same time, it is convenient for the silica gel desiccant to absorb moisture inside the cabinet 2 to achieve a moisture-proof effect. It should be noted that the silica gel desiccant will change color after absorbing moisture. The darker the color is compared to the initial state, the more moisture it absorbs. Subsequent replacement can be distinguished based on the depth of the color.
[0061] Reference Figures 1 to 13As shown, the outer walls of the two rain shields 32 are provided with semicircular through holes 320 for the lightning rod 40 to pass through, and a sealing ring 400 is fixedly provided on the bottom outer wall of the lightning rod 40. A sealing strip 321 is fixedly provided on the top of one of the rain shields 32, and an arc-shaped notch for accommodating the sealing ring 400 is provided on the outer wall of the sealing strip 321. The sealing strip 321 can cover the tightened gap after the two rain shields 32 are tightened to prevent rainwater from flowing into the outer wall of the cabinet 2 through the gap. The two semicircular through holes 320 facilitate the lightning rod 40 to pass through between the two rain shields 32, and at the same time provide an accommodating space for the sealing ring 400 on the bottom outer wall of the lightning rod 40. The sealing ring 400 can prevent rainwater from flowing into the outer wall of the cabinet 2 from the gap between the lightning rod 40 and the two semicircular through holes 320, and at the same time prevent the wire 420 from getting damp.
[0062] Reference Figures 1 to 13 As shown, a protective door 26 is hingedly provided on the outer wall of one end of the cabinet 2, a handle is fixedly provided on the outer wall of the protective door 26, a protective shell 27 is fixedly provided on the outer wall of the other end of the cabinet 2, and avoidance gaps for swinging of two first connecting rods 311 and two second connecting rods 312 are symmetrically provided at both ends of the protective shell 27, a lightning sensor 270 is fixedly provided on the outer wall of the protective shell 27, the lightning sensor 270 is electrically connected to the controller, a detection head is installed on the top of the lightning sensor 270, the detection head can sense the lightning signal and transmit the signal to the inside of the controller, the signal line of the lightning sensor 270 needs to be connected to the digital input port of the controller or PLC, so that the lightning situation can be monitored through the lightning sensor 270, and when lightning is detected, the signal is sent to the controller, the protective door 26 is used to protect the power distribution equipment 20 inside the cabinet 2, and the protective shell 27 covers and protects the drive component 30 and the telescopic component 31 inside the cabinet 2.
[0063] The working principle of the present invention is as follows: a detection head is installed on the top of the lightning sensor 270, which can sense the lightning signal and transmit the signal to the inside of the controller. The signal line of the lightning sensor 270 needs to be connected to the digital input port of the controller or PLC, so that the lightning situation can be monitored through the lightning sensor 270. When lightning is detected, the signal is sent to the controller. The protective door 26 is used to protect the power distribution equipment 20 inside the cabinet 2, and the protective shell 27 covers and protects the drive component 30 and the telescopic component 31 inside the cabinet 2.
[0064] When the controller receives the lightning signal, the controller starts the electric push rod 300 so that its output end extends upward. Since its output end is fixedly connected to the first rack 301, the first rack 301 is slidably connected to the first slide rail, the first gear 302 is meshed with the first rack 301, and the first gear 302 is fixedly connected to one of the first hinge shafts, the first rack 301 slides up in the first slide rail and drives one of the first hinge shafts to rotate counterclockwise.
[0065] When one of the first hinge shafts rotates counterclockwise, due to the meshing connection of the two umbrella teeth 310, the two first connecting rods 311 and the two second connecting rods 312 are respectively fixedly connected to the four first hinge shafts, and the two umbrella teeth 310 are respectively fixedly connected to one end of one of the first connecting rods 311 and one of the second connecting rods 312, and each first connecting rod 311 and each second connecting rod 312 One end away from the umbrella tooth 310 is hinged to the side wall of one of the rain shields 32, and then the two first connecting rods 311 and the two second connecting rods 312 drive the two rain shields 32 to approach each other until they are tightened. It should be noted that the model drawn in this application is a state of action completion. In the initial state, the two rain shields 32 are far away from each other, and the lightning rod 40 is also stored inside the cabinet 2. Only when thunderstorm weather is detected, the two rain shields 32 need to be approached to each other until they are tightened to shield the top of the cabinet 2 from rain, and the synchronous belt 540 drives the lightning rod 40 to extend from the inside of the cabinet 2 to perform lightning protection operations.
[0066] Since the two telescopic springs 412 are initially contracted and the first pull rope 410 is in a taut state, when the two rain shields 32 initially approach each other, the first pull rope 410 will be in a short relaxed state, thereby causing the two telescopic springs 412 to change from a contracted state to a stretched state. Since one end of the bottom of the lifting plate 411 and the top of each support rod are in contact with the two ends of a telescopic spring 412, the bottom of the lifting plate 411 and the bottom of one of the rain shields 32 are respectively fixedly connected to the two ends of the first pull rope 410, so that the lifting plate 411 slides upward synchronously on the outer walls of the two guide rods 210 until the lightning rod 40 on the top of the lifting plate 411 extends out from the semicircular through hole 320 between the two rain shields 32 when the two rain shields 32 are tightened, in preparation for lightning protection. Here, it should be noted that the lightning rod 40 is designed as a retractable structure, that is, it is initially located inside the cabinet 2, which can avoid the existing lightning rod 40 from being worn out by long-term exposure to the sun and wind due to being installed outside the cabinet 2, thereby reducing its service life and thus reducing the cost of lightning protection.
[0067] During thunderstorms, the charged clouds in the air gather a large amount of charge at the tip of the lightning rod 40 due to electrostatic induction. When the cloud layer has a large amount of charge, the air between the lightning rod 40 and the cloud layer is easily broken down and becomes a conductor. In this way, a passage is formed between the charged cloud layer and the lightning rod 40. Since the bottom end of the lightning rod 40 is electrically connected to the grounding block 422 through the wire 420, the lightning rod 40 can conduct the positive charge on the cloud layer into the earth through the grounding block 422, forming a downward current, neutralizing the potential difference between the cloud layer and the earth, so that the air will not be broken down due to the potential difference and discharge to the distribution cabinet, thereby achieving a lightning protection effect. When the lifting plate 411 rises, the wire 420 is fixedly connected to the lightning rod 40 on the lifting plate 411, so that the wire 420 is automatically unwound on the reel 421 and rises synchronously with the lightning rod 40, that is, the reel 421 unwinds the wire counterclockwise, thereby driving the wire reel 421 to reel in parallel with the reel. The second gear 424 coaxial with the disk 421 rotates counterclockwise. Since the second gear 424 is meshed and connected with the second rack 423, the second rack 423 is slidably connected with the second slide rail, thereby driving the second rack 423 to slide up inside the second slide rail. Since the bottom of the second rack 423 and the inner wall of the second slide rail are respectively fixedly connected to the two ends of the first return spring 426, the first return spring 426 is transformed from an initial state to a stretched state. Every time the lifting block drives the lightning rod 40 to retract into the cabinet 2, the second rack 423 driven by the first return spring 426 slides down, thereby driving the second gear 424 to rotate clockwise, thereby driving the winding reel 421 to reel in the wire 420 in a clockwise direction, thereby realizing the resetting of the wire 420 and preventing the wire 420 from drooping inside the cabinet 2 and being entangled with the first pull rope 410, thereby avoiding affecting the grounding operation of the lightning rod 40.
[0068] When the two rain shields 32 are close to each other and closed, that is, when the lightning rod 40 is extended, since the other rain shield 32 and one end of the third rack 531 are respectively fixedly connected to the two ends of the second pull rope 530, the third rack 531 is slidably connected to the second guide rail 23, thereby driving the third rack 531 to slide inside the second guide rail 23 toward one end close to the third guide wheel 534. Since the third gear 532 is fixedly connected to the top end of one of the third hinge shafts, the third rack 531 is meshed with the third gear 532, thereby driving one of the third hinge shafts close to the conductor 420 to rotate clockwise. At the same time, since the other end of the third rack 531 and the inner wall of the second guide rail 23 are respectively fixedly connected to the two ends of the second reset spring sliding, the second reset spring 533 is driven to change from the initial state to the stretched state.
[0069] When one of the third hinge shafts close to the wire 420 rotates clockwise, since the two synchronous wheels 543 are fixedly connected to the two third hinge shafts respectively, the two synchronous wheels 543 are sleeved by the synchronous belt 540, the swing rod 541 is fixedly connected to one of the third hinge shafts away from the third gear 532, and the end of the swing rod 541 away from the third hinge shaft and the hopper 52 are respectively hinged to the two ends of the top rod 542, and the hopper 52 is slidably connected to the spreading plate 51, thereby driving the hopper 52 to move on the spreading plate The inside of 51 slides from left to right, silica gel desiccant is stored in the hopper 52, a row of discharge holes 520 are designed at the bottom of the hopper 52, and a plurality of rows of throwing holes 510 are designed at equal intervals inside the spreading plate 51. Since each discharge hole 520 is consistent with the diameter of a throwing hole 510, when the hopper 52 slides from left to right inside the spreading plate 51, each time a row of discharge holes 520 overlaps with a row of throwing holes 510, the silica gel desiccant is thrown once.
[0070] While sprinkling the silica gel desiccant, the two electric slides 24 are started, thereby driving the tray 50 to rise through the two sliders 25 until it rises to the bottom of the scattering tray 51 and maintains a close distance from the scattering tray 51, so that the scattered silica gel desiccant can accurately fall into the interior of several storage tanks 500, and will not cause the desiccant to break or splash to the outside of the tray 50 due to the high sprinkling height, which is convenient for the later replacement of the desiccant after it fails. When several storage tanks 500 are sprinkled with silica gel desiccant, the two sliders 25 on the two electric slides 24 drive the tray 50 to descend to the inner bottom of the cabinet 2, which can avoid affecting the power distribution equipment 20. At the same time, it is convenient to absorb the moisture inside the cabinet 2 through the silica gel desiccant to achieve a moisture-proof effect. It should be noted that the silica gel desiccant will change color after absorbing moisture. The darker the color becomes compared with the initial state, the more moisture it absorbs. Subsequent replacement can be distinguished according to the depth of color.
[0071] The sealing strip 321 can cover the closing gap after the two rain shields 32 are closed to prevent rainwater from flowing into the outer wall of the cabinet 2 through the gap. The two semicircular through holes 320 facilitate the lightning rod 40 to pass through between the two rain shields 32, and at the same time provide an accommodation space for the sealing ring 400 on the bottom outer wall of the lightning rod 40. The sealing ring 400 can prevent rainwater from flowing into the outer wall of the cabinet 2 from the gap between the lightning rod 40 and the two semicircular through holes 320, and at the same time prevent the wire 420 from getting damp.
