Description
Technical Field
[0001] This invention relates to the field of power distribution cabinet technology, specifically to an outdoor high and low voltage power distribution cabinet. Background Technology
[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. Depending on the installation scenario, they can be divided into indoor distribution cabinets and outdoor distribution cabinets. Outdoor distribution cabinets are more affected by environmental factors. When used outdoors, sand and gravel entering the distribution cabinet can seriously threaten the safety and stable operation of the equipment.
[0003] In existing outdoor high and low voltage distribution cabinets, external sand and gravel can penetrate the heat dissipation holes and enter the battery box. Sand and gravel are hard particles that can scratch internal components and power lines after entering the distribution cabinet, thereby affecting the normal operation and lifespan of internal components. Furthermore, severe damage to the power lines can cause short circuits and safety accidents. If the distribution cabinet does not have heat dissipation holes to prevent sand and gravel from entering, the distribution cabinet will not be able to dissipate heat, and the internal temperature will continue to rise, which will also affect the normal use of internal components and may even cause the distribution cabinet to catch fire. Summary of the Invention
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an outdoor high and low voltage distribution cabinet that solves the problem of external sand and gravel entering the battery box through the heat dissipation holes. Sand and gravel are hard particles that can scratch internal components and power lines after entering the distribution cabinet, thus affecting the normal operation and lifespan of internal components. Furthermore, severe damage to the power lines can cause short circuits and safety accidents. If the distribution cabinet does not have heat dissipation holes to prevent sand and gravel from entering, the distribution cabinet cannot dissipate heat, and the internal temperature will continue to rise, which will also affect the normal use of internal components and even cause the distribution cabinet to catch fire.
[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an outdoor high and low voltage distribution cabinet, comprising a cabinet body, wherein a PLC controller is fixedly installed inside the cabinet body, and sand and gravel prevention mechanisms are provided on both sides of the cabinet body. The sand and gravel prevention mechanism includes a blocking mechanism, a carrier mechanism, a rotating mechanism, and a discharge mechanism. The blocking mechanism is located inside the carrier mechanism, the carrier mechanism is located inside the rotating mechanism, the rotating mechanism is located inside the discharge mechanism, and the discharge mechanism is located on the side of the cabinet body.
[0006] In this invention, the sand-proof mechanism is controlled by a PLC controller to prevent sand from entering through the heat dissipation holes and affecting the normal use of the internal components of the cabinet. When the sand-proof mechanism is working, it uses a blocking mechanism to block the sand, preventing it from entering the cabinet. When the blocking mechanism needs to be cleaned or repaired, it and the carrier mechanism are removed from the rotating mechanism together, so that the removed blocking mechanism can be cleaned and repaired. Then it is reinstalled in the rotating mechanism, which can rotate and pour the blocked sand into the discharge mechanism, and finally discharge it through the discharge mechanism.
[0007] Preferably, the barrier mechanism includes a barrier box, a circular hole is provided on one side of the barrier box, the circular hole is located on the outside of the cabinet, a baffle is fixedly connected inside the barrier box, and a filter screen is fixedly connected to the surface of the baffle.
[0008] Preferably, an arc-shaped plate is fixedly connected to the top of one side of the baffle, the arc-shaped plate is located on the top side of the filter screen, a first anti-sand plate is fixedly connected between the top of the arc-shaped plate and the baffle, a second anti-sand plate is fixedly connected to the bottom of one side of the baffle, and a C-shaped plate is fixedly connected to the other side of the baffle, the C-shaped plate is located on one side of the filter screen, and a vent hole is provided on the top of the C-shaped plate.
[0009] In this invention, when the barrier mechanism prevents sand and gravel from entering the cabinet, the sand and gravel splashes through the round hole into the barrier box. The sand and gravel are then splashed onto the surface of the first or second sand-proof plate and blocked, falling to the front of the baffle. The first and second sand-proof plates prevent the sand and gravel from splashing left and right after entering the barrier box, causing it to fall along the direction of the plate. This effectively blocks the sand and gravel in front of the baffle. Smaller sand and gravel are blocked by the filter screen, and the arc-shaped plate prevents the sand and gravel from spraying directly onto the surface of the filter screen, thus providing good protection for the filter screen. If fine sand and gravel pass through the filter screen, it is intercepted by the C-shaped plate. Then, clean air enters the cabinet through the vent, thereby preventing sand and gravel from entering the interior of the cabinet.
[0010] Preferably, the carrier mechanism includes an insert, the barrier box is inserted into the interior of the insert, a limit strip is fixedly connected to the inner side of the insert, an insertion block is provided on one side of the surface of the insert, a pull handle is provided on one side of the insert, and a fan is fixedly installed on the other side of the insert.
[0011] In this invention, the barrier mechanism is placed in the carrier mechanism, which facilitates the removal and rotation of the carrier mechanism and the barrier mechanism together. When inserting, the barrier box is inserted into the interior of the insert until one side of the barrier box reaches the surface of the limiting strip. At this time, the other side of the barrier box is just flush with the surface of the insert. To remove the barrier mechanism, the handle is manually pulled outward to disengage the barrier box from the interior of the insert, thereby removing the barrier mechanism from the carrier mechanism. The fan can be used to dissipate heat from the interior of the cabinet, preventing the internal temperature of the cabinet from becoming too high and causing damage to the internal components, thus extending the service life of the cabinet.
[0012] Preferably, the rotating mechanism includes a rotating ring, with a slot on one side of the inner side of the rotating ring, the insert block being inserted into the slot, and a limiting ring being fixedly connected to the surface of the rotating ring, with two limiting rings provided.
[0013] Preferably, the surface of the rotating ring is provided with a toothed groove, and a limiting plate is fixedly connected to the surface of the rotating ring. The limiting plate is located at both ends of the toothed groove, and the toothed groove is located on the side away from the limiting ring. A first motor is fixedly installed on the inner wall of the cabinet, and a gear is fixedly connected to the output end of the first motor. The gear is meshed with the inside of the toothed groove.
[0014] In this invention, when a large amount of sand and gravel is collected in the barrier mechanism, the rotating mechanism drives the carrier mechanism and the barrier mechanism to rotate, causing the barrier mechanism to tilt. This allows the sand and gravel in the barrier mechanism to flow from the first and second through holes to the discharge mechanism, and finally be discharged through the discharge mechanism. During rotation, the PLC controller starts the first motor to drive the gear to rotate. The gear drives the rotating ring to rotate through the tooth groove. Since the insert is inserted into the slot, the embedded body is fixed in the rotating ring. The rotating ring drives the embedded body to rotate, and the embedded body drives the barrier box to rotate. Therefore, the sand and gravel in the C-shaped plate enter the discharge mechanism through the first through hole, and the sand and gravel in front of the baffle also enter the discharge mechanism through the second through hole. During the rotation of the rotating ring, a limiting ring prevents the rotating ring from slipping out of the discharge shell, and a limiting plate prevents the gear from rotating out of the tooth groove when rotating in the tooth groove. The limiting ring and limiting plate ensure that the rotating mechanism operates more stably.
[0015] Preferably, the discharge mechanism includes a discharge shell, which is fixedly connected to the side wall of the cabinet. The rotating ring is located inside the discharge shell, and the two limiting rings are respectively locked on both sides of the inner circle of the discharge shell. A cavity is opened on the bottom side of the interior of the discharge shell.
[0016] Preferably, a first through hole is provided between the barrier box, the insert and the rotating ring, and the first through hole is located on one side of the C-shaped plate. A second through hole is provided between the barrier box, the insert and the rotating ring, and the second through hole is located on the bottom side of the second sandproof plate. The first through hole and the second through hole both penetrate the interior of the cavity and are located on the same side of the cavity.
[0017] Preferably, a second motor is fixedly installed inside the discharge shell, and a conveying auger is fixedly connected to the output end of the second motor. The other end of the conveying auger is rotatably connected to the inner wall of the discharge shell.
[0018] Preferably, a cover plate is rotatably connected to one bottom side of the discharge shell, the cover plate being located at the output end of the conveying auger, and guide plates are fixedly connected to both sides inside the discharge shell, the guide plates being located between the rotating ring and the conveying auger.
[0019] In this invention, gravel enters the discharge shell through the first and second through holes and then enters the cavity of the discharge shell. The collected gravel is then guided by the guide plate to the bottom of the discharge shell. Finally, the second motor is started to drive the conveying auger to rotate, and the conveying auger discharges the gravel out of the discharge shell. Since the top of the cover plate is rotatably connected to the discharge shell, it opens during conveying and closes by its own gravity after conveying, preventing external gravel from entering the discharge shell.
[0020] (III) Beneficial Effects This invention provides an outdoor high and low voltage distribution cabinet. It has the following beneficial effects: (i) This outdoor high and low voltage distribution cabinet can effectively intercept sand and gravel attempting to enter the distribution box through its anti-sand and gravel mechanism, preventing them from scratching the surface of internal components or even power lines after entering the cabinet. It provides reliable physical protection for internal components and power lines, avoiding damage to components and power lines, as well as dangerous accidents caused by short circuits. While blocking sand and gravel, it does not obstruct normal air circulation. Good air circulation can promptly remove the heat generated by the internal components of the distribution box during operation, ensuring that the internal temperature environment of the cabinet is maintained and ensuring that the distribution box operates efficiently under safe and stable conditions.
[0021] (II) This outdoor high and low voltage distribution cabinet, through the setting of the rotating mechanism and the discharge mechanism, when a large amount of sand and gravel is collected in the barrier mechanism, the rotating mechanism drives the barrier mechanism to tilt as a whole, so that the sand and gravel inside enters the discharge mechanism through the first through hole and the second through hole, and finally is discharged from the cabinet through the discharge mechanism. This ensures that there is sufficient collection space inside the barrier mechanism and that the sand and gravel are discharged from the distribution cabinet in a timely manner. The whole process is automatic and does not require manual operation, making it very convenient and efficient to use.
[0022] (III) This outdoor high and low voltage distribution cabinet, through the setting of plugs, slots, isolation boxes and embedded bodies, allows the isolation mechanism to be removed as a whole for inspection, which is convenient for maintenance and replacement. It also allows the embedded body to be disassembled and the fan on its back to be maintained or replaced, ensuring the normal operation of the isolation mechanism and heat dissipation components. Moreover, the disassembly and assembly are convenient and quick. By removing and replacing it separately, the entire distribution cabinet is not inspected, saving maintenance costs and improving maintenance efficiency.
[0023] (iv) This outdoor high and low voltage distribution cabinet can collect the intercepted sand and gravel through the barrier mechanism, and can also discharge the collected sand and gravel into the discharge shell in a timely manner, preventing a large amount of sand and gravel from accumulating in the barrier box and preventing instability caused by outside air blowing towards the sand and gravel. Even if the distribution cabinet shakes, it can prevent the sand and gravel from splashing and scattering, ensuring that the sand and gravel are always within a controllable collection range, greatly improving the sand and gravel collection effect and ensuring the stability and cleanliness of the internal environment of the distribution cabinet.

Detailed Implementation
[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] See Figure 1-15 The present invention provides a technical solution: an outdoor high and low voltage distribution cabinet, the structure of which includes a cabinet body 1, a PLC controller 2 fixedly installed inside the cabinet body 1, and anti-sand and gravel mechanism 3 provided on both sides of the cabinet body 1. The anti-sand and gravel mechanism 3 includes a blocking mechanism 31, a carrier mechanism 32, a rotating mechanism 33 and a discharge mechanism 34. The blocking mechanism 31 is located inside the carrier mechanism 32, the carrier mechanism 32 is located inside the rotating mechanism 33, the rotating mechanism 33 is located inside the discharge mechanism 34, and the discharge mechanism 34 is located on the side of the cabinet body 1.
[0028] Specifically, the PLC controller 2 controls the sand and gravel prevention mechanism 3 to prevent sand and gravel from entering through the heat dissipation holes and affecting the normal use of the internal components of the cabinet 1, reducing the wear of sand and gravel on the internal components of the cabinet 1, extending the service life of the internal components, and thus extending the service life of the cabinet 1. When the sand and gravel prevention mechanism 3 is working, it uses the blocking mechanism 31 to block the sand and gravel, preventing the sand and gravel from entering the interior of the cabinet 1. When it is necessary to clean or repair the blocking mechanism 31, it is removed from the rotating mechanism 33 along with the carrier mechanism 32, so that the removed blocking mechanism can be cleaned and repaired. Then it is reinstalled into the rotating mechanism 33, which can rotate and pour the blocked sand and gravel into the discharge mechanism 34, and finally discharge it through the discharge mechanism 34, thereby preventing sand and gravel from entering the cabinet 1.
[0029] The barrier mechanism 31 includes a barrier box 311, a circular hole 312 is provided on one side of the barrier box 311, the circular hole 312 is located on the outside of the cabinet 1, a baffle 313 is fixedly connected inside the barrier box 311, and a filter screen 314 is fixedly connected to the surface of the baffle 313.
[0030] Among them, an arc-shaped plate 315 is fixedly connected to the top of one side of the baffle 313. The arc-shaped plate 315 is located on the top side of the filter screen 314. A first sandproof plate 316 is fixedly connected between the top of the arc-shaped plate 315 and the baffle 313. A second sandproof plate 317 is fixedly connected to the bottom of one side of the baffle 313. A C-shaped plate 318 is fixedly connected to the other side of the baffle 313. The C-shaped plate 318 is located on one side of the filter screen 314. A vent hole 319 is opened on the top of the C-shaped plate 318.
[0031] Specifically, the barrier mechanism 31 prevents sand and gravel from entering the cabinet 1. If sand and gravel pass through the round hole 312 and splash into the barrier box 311, the sand and gravel are splashed onto the surface of the first sandproof plate 316 or the second sandproof plate 317, and then blocked and fall to the front of the baffle 313. The long-term barrier causes large sand and gravel particles that cannot pass through the filter screen 314 to accumulate here. The first sandproof plate 316 and the second sandproof plate 317 can prevent sand and gravel from splashing left and right after entering the barrier box 311, causing them to fall along the direction of the plate. Thus, the sand and gravel are well blocked in front of the baffle 313. The filter screen 314 is used to block smaller sand and gravel, and the arc plate 315 is used to prevent sand and gravel from spraying directly onto the surface of the filter screen 314, which plays a good protective role for the filter screen 314. If fine sand and gravel pass through the filter screen 314, the C-shaped plate 318 intercepts it. Then, clean air enters the cabinet 1 through the vent 319, thereby preventing sand and gravel from entering the interior of the cabinet 1.
[0032] The carrier mechanism 32 includes an insert 321, a barrier box 311 inserted into the interior of the insert 321, a limit strip 322 fixedly connected to the inner side of the insert 321, an insert block 323 opened on one side of the surface of the insert 321, a pull handle 324 opened on one side of the insert 321, and a fan 325 fixedly installed on the other side of the insert 321.
[0033] Specifically, the blocking mechanism 31 is placed inside the carrier mechanism 32, making it convenient to remove and rotate the carrier mechanism 32 and the blocking mechanism 31 together. When inserting, the blocking box 311 is inserted into the insert 321 until one side of the blocking box 311 reaches the surface of the limiting strip 322. At this point, the other side of the blocking box 311 is flush with the surface of the insert 321. To remove the blocking mechanism 31, the pull handle 324 is manually pulled outwards to detach the blocking box 311 from the insert 321, thereby removing the blocking mechanism 31 from the carrier mechanism. Remove the fan 325 from the slot 332 to dissipate heat from the inside of the cabinet 1, preventing overheating and damage to internal components, thus extending the lifespan of the cabinet 1. When the fan 325 malfunctions, remove the insert 323 from the slot 332 to remove the insert 321, allowing the fan 325 on the back of the insert 321 to be repaired or replaced. This ensures the fan 325's normal heat dissipation function, maintains stable internal temperature of the cabinet 1, and prevents high internal temperature from damaging or aging components.
[0034] The rotating mechanism 33 includes a rotating ring 331, with a slot 332 on one side of the inner side of the rotating ring 331. A plug 323 is inserted into the inside of the slot 332. A limit ring 333 is fixedly connected to the surface of the rotating ring 331, and there are two limit rings 333.
[0035] The rotating ring 331 has a toothed groove 334 on its surface. A limiting plate 335 is fixedly connected to the surface of the rotating ring 331. The limiting plate 335 is located at both ends of the toothed groove 334. The toothed groove 334 is located on the side away from the limiting ring 333. A first motor 336 is fixedly installed on the inner wall of the cabinet 1. A gear 337 is fixedly connected to the output end of the first motor 336. The gear 337 is meshed with the inside of the toothed groove 334.
[0036] Specifically, when a large amount of sand and gravel is collected in the blocking mechanism 31, the rotating mechanism 33 drives the carrier mechanism 32 and the blocking mechanism 31 to rotate, causing the blocking mechanism 31 to tilt. This allows the sand and gravel in the blocking mechanism 31 to flow from the first through hole 343 and the second through hole 344 to the discharge mechanism 34, and finally be discharged through the discharge mechanism 34. During rotation, the PLC controller 2 starts the first motor 336, which drives the gear 337 to rotate. The gear 337 drives the rotating ring 331 to rotate through the tooth groove 334. Since the insert block 323 is inserted into the slot 332, the insert 321 is fixed in the rotating ring 331, thus the rotating ring... 331 drives the insert 321 to rotate, and the insert 321 drives the barrier box 311 to rotate. Therefore, the gravel in the C-shaped plate 318 enters the discharge mechanism 34 through the first through hole 343, and the gravel in the front side of the baffle 313 also enters the discharge mechanism 34 through the second through hole 344. During the rotation of the rotating ring 331, the limiting ring 333 prevents the rotating ring 331 from slipping out of the discharge shell 341, and the limiting plate 335 prevents the gear 337 from rotating out of the tooth groove 334 when it rotates in the tooth groove 334. Thus, the setting of the limiting ring 333 and the limiting plate 335 makes the operation of the rotating mechanism 33 more stable.
[0037] The discharge mechanism 34 includes a discharge shell 341, which is fixedly connected to the side wall of the cabinet 1. A rotating ring 331 is located inside the discharge shell 341, and two limiting rings 333 are respectively locked on both sides of the inner circle of the discharge shell 341. A cavity 342 is opened on the bottom side inside the discharge shell 341.
[0038] Among them, the barrier box 311, the insert 321 and the rotating ring 331 are provided with a first through hole 343, which is located on one side of the C-shaped plate 318. The barrier box 311, the insert 321 and the rotating ring 331 are provided with a second through hole 344, which is located on the bottom side of the second sandproof plate 317. The first through hole 343 and the second through hole 344 both penetrate the interior of the cavity 342 and are located on the same side of the cavity 342.
[0039] The discharge shell 341 has a second motor 345 fixedly installed inside, and the output end of the second motor 345 is fixedly connected to a conveying auger 346. The other end of the conveying auger 346 is rotatably connected to the inner wall of the discharge shell 341.
[0040] Among them, a cover plate 347 is rotatably connected to one bottom side of the discharge shell 341. The cover plate 347 is located at the output end of the conveying auger 346. Guide plates 348 are fixedly connected to both sides inside the discharge shell 341. The guide plates 348 are located between the rotating ring 331 and the conveying auger 346.
[0041] Specifically, the gravel enters the discharge shell 341 through the first through hole 343 and the second through hole 344, and then enters the cavity 342 of the discharge shell 341. Afterwards, the collected gravel is guided by the guide plate 348 to enter the bottom of the discharge shell 341. Finally, the second motor 345 is started to drive the conveying auger 346 to rotate. The conveying auger 346 discharges the gravel out of the discharge shell 341. Since the top of the cover plate 347 is rotatably connected to the discharge shell 341, it opens during conveying and closes by its own gravity after conveying to prevent external gravel from entering the discharge shell 341.
[0042] Working principle: First, the sand and gravel enter the barrier box 311 through the round hole 312. Then, it is blocked by the first sandproof plate 316 or the second sandproof plate 317 and falls to the front of the baffle 313. The filter plate allows air to pass through the baffle 313 and enter the C-shaped plate 318. Finally, it enters the cabinet 1 through the vent 319. The arc plate 315 can prevent sand and gravel from splashing directly onto the filter plate and clogging it. If fine sand and gravel pass through the filter plate, it will be intercepted by the C-shaped plate 318. After a long period of collection, the sand and gravel will first accumulate in front of the baffle 313 and in the C-shaped plate 318. Then, the first motor 336 is started to drive the gear 337 to rotate. The gear 337 drives the rotating ring 331 to rotate through the tooth groove 334. Since the insert 323 is inserted into the slot 332, the embedded body 3 21 is fixed in the rotating ring 331, so the rotating ring 331 drives the insert 321 to rotate, and the insert 321 drives the barrier box 311 to rotate. Therefore, the gravel in the C-shaped plate 318 enters the discharge mechanism 34 through the first through hole 343. The gravel in the front side of the baffle 313 also enters the discharge shell 341 through the second through hole 344 and enters the cavity 342 of the discharge shell 341. Then, the collected gravel is guided by the guide plate 348 to enter the bottom of the discharge shell 341. Finally, the second motor 345 is started to drive the conveying auger 346 to rotate. The conveying auger 346 discharges the gravel out of the discharge shell 341. Since the top of the cover plate 347 is rotatably connected to the discharge shell 341, it opens during conveying and closes by its own gravity after conveying to prevent external gravel from entering the discharge shell 341.
