Description

Technical Field

[0001] This invention belongs to the field of smart grid distribution cabinet technology, specifically a smart power distribution cabinet with a protection mechanism. Background Technology

[0002] With the rapid development of smart grids, power distribution cabinets, as core equipment of power distribution systems, are widely used in industrial production, commercial buildings, and residential communities. Their operational stability is directly related to the safety and reliability of power supply. This equipment integrates high-precision sensors and computer motherboard technology to monitor parameters such as current, energy, and harmonics of the main power supply and 84 feeders in real time. It has temperature monitoring and online leakage detection functions, adopts an HMI integrated display unit, and supports data uploading to the back-end system to achieve real-time monitoring and operation management. Compared with traditional distribution cabinets, it supports more circuits, integrates multi-layer alarm mechanisms for faults such as overload and voltage abnormality, can save 3,000 historical records for auxiliary analysis, and its modular design improves installation flexibility and stability.

[0003] Existing power distribution cabinets mostly adopt a fixed cabinet structure, which has poor dustproof and heat dissipation performance. They are easily invaded by external dust and moisture, leading to corrosion of internal electrical components. In addition, most power distribution cabinets in the current technology are not equipped with real-time monitoring modules, so they cannot dynamically sense key parameters such as abnormal temperature and humidity inside the cabinet. When environmental parameters exceed the standard, they cannot be prevented and dealt with in time. Problems are often only discovered after a fault occurs, which affects the continuity of power supply. Summary of the Invention

[0010] Preferably, the upper straight section of the F-shaped suction tube is a rigid tube, while the rest is a flexible tube. Dust collection hoppers are fixedly connected to both ends of the F-shaped suction tube, and the two dust collection hoppers are respectively connected to the two groove plates and tightly engaged.

[0011] Preferably, the rotary dehumidification structure includes two horizontal plates, and folding curtains are fixedly connected to the upper and lower outer walls of the two horizontal plates. The cabinet of the intelligent power distribution cabinet is provided with a rectangular sliding groove that can be fixedly connected to the two sets of folding curtains respectively. A U-shaped convex panel is fixedly connected to one end of the two horizontal plates, and a convex wheel is rotatably connected to the inner wall of the two U-shaped convex panels.

[0012] Preferably, a second rotating rod is fixedly connected through the convex rotating wheel. A double-ring sleeve is movably sleeved on the body of the second rotating rod, and the bottom end of the double-ring sleeve is fixedly connected to the inner wall of the bottom end of the intelligent power distribution cabinet. A rotating cylinder containing desiccant particles is fixedly connected to one end of the second rotating rod. The cylinder is made of a series of solid plates and hollow mesh plates joined together.

[0013] Preferably, a humidity sensor is fixedly connected to the other end of the rotating rod, a micro motor is fixedly connected to the other end of the rotating cylinder, a cylinder rod is fixedly connected to the shaft of the micro motor, a long sliding rod is rotatably connected to the inner wall of the cylinder rod, two support cylinders are fixedly connected to the long sliding rod, and a curved solid plate is fixedly connected to each of the two support cylinders.

[0014] Preferably, each of the arc-shaped solid plates is respectively attached to the inner wall of the area where the hollow mesh plate is opened on the rotating cylinder, and multiple magnetic plates are fixedly connected around the inner wall of the rotating cylinder, and each of the arc-shaped solid plates can be magnetically connected to each of the magnetic plates respectively.

Two locking blocks are fixedly connected to both ends of the long sliding rod on one side. The inner walls of both ends of the cylindrical rod are also provided with locking grooves that can intermittently engage with the two sets of locking blocks. The two sets of locking blocks can also intermittently fit and rotate with the inner walls of the cylindrical rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a telescopic electric cylinder to drive the meshing assembly, causing the slot plate to rotate and change its tilt angle, up to 90 degrees, thereby adjusting the gas flow to adapt to different heat dissipation needs. Simultaneously, when the slot plate tilts, a spring drives a T-shaped baffle to remain in contact with the slot plate, ensuring that airflow passes through the filter screen and preventing unfiltered air from entering the cabinet. When the slot plate returns to its original position, an elastic telescopic ring drives the filter screen to return to its original position. The slot plate opening first scrapes dust from the filter screen surface, and then a soft-bristled scraper cleans the filter holes to remove any clogged dust. This double cleaning reduces filter screen blockage. Furthermore, the piston negative pressure structure is linked to the toothed plate, generating suction by the movement of the T-shaped piston rod within the piston cylinder. Dust is collected from the slot plate through an F-shaped suction pipe and a dust collection bucket, and then discharged through compression, preventing dust accumulation from affecting equipment operation.

[0016] 2. This invention uses a toothed plate to synchronously drive the rotating drum in the dehumidification structure, which in turn rotates the absorbent cotton sleeve to absorb moisture. This prevents insulation aging and metal corrosion of the electrical distribution structure inside the cabinet due to moisture. At the same time, the rotating support plate generates directional airflow, which helps to remove hot air from inside the cabinet and avoids local overheating. When the humidity sensor detects excessive humidity, it triggers a micro motor to operate. Through a series of transmission structures, the curved solid plate is disengaged from the seal of the rotating drum's perforated mesh plate. The soft rubber brush moves the desiccant particles, allowing them to fully contact the gas inside the cabinet, achieving secondary adsorption of moisture. This significantly improves the reliability of dehumidification and achieves an intelligent secondary dehumidification effect.

[0017] 3. This invention uses a rotating meshing structure as the core drive, which simultaneously drives the operation of multiple structures such as dust prevention, heat dissipation, dust collection, and dehumidification. There is no need to set up separate drive components for each function. The absorbent cotton sleeve is installed on the support plate by a sleeve method, which is convenient to disassemble and replace. The handling of dust and moisture is automated, reducing the frequency of manual cleaning and component replacement, reducing operation and maintenance costs, and extending the overall service life of the power distribution cabinet.

[0020] 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.

[0021] like Figures 1 to 10 As shown, the present invention provides an intelligent power distribution cabinet with a protection mechanism, including an intelligent distribution cabinet 1. A heat dissipation plate groove 2 is fixedly connected through one end of the cabinet near the bottom of the intelligent distribution cabinet 1. Two groove plates 7 are attached to the inner wall of the heat dissipation plate groove 2. A filter screen 9 for filtering dust in the air is attached and slidably connected between the two groove plates 7. A rotating engagement structure is provided between the outer wall of one end of the heat dissipation plate slot 2 and the two slot plates 7 to control the degree of tilting and opening of the two slot plates 7. A piston negative pressure structure is provided on the rotating engagement structure to collect the small amount of dust in the two slot plates 7. Two rotating dehumidification structures are also provided on the side of the rotating engagement structure to prevent excessive moisture in the intelligent power distribution cabinet 1.

[0022] Using the above scheme: its movable end drives the toothed plate in the meshing assembly 4 to move upward, thereby meshing and driving the two gears to rotate, so that the two drive the rotating rod 6 and the slot plate 7 to rotate in the same direction. The tilting of the two slot plates 7 will stretch and cause the filter screen 9 to tilt. The closer the tilting angle of the slot plate 7 is to 90 degrees, the greater the passive tilting and bending angle of the filter screen 9. During the process of natural gas flow to dissipate heat from the intelligent power distribution cabinet 1, it will completely pass through the filter screen 9 and through the F-shaped suction pipe 16 and the dust collection buckets installed at its two ends, the trough... Dust that has been swept by the soft-bristled scraper 10 before being collected in the plate 7 is drawn into the piston cylinder 15. When the T-shaped piston rod 14 moves upward passively, the small amount of dust in the inner cavity is discharged through the special-shaped conveying pipe 17. The rotating rod 23 and the rotating cylinder 24 rotate synchronously at a fixed point under the positioning of the double ring sleeve rod. The rotating cylinder 24 can drive multiple fixed support plates 25 and the absorbent cotton sleeves 26 sleeved on the support plates 25 to rotate. The rotating absorbent cotton sleeves 26 can absorb the moisture in the intelligent power distribution cabinet 1.

[0023] The rotary meshing structure includes a telescopic electric cylinder 3 fixedly connected to the outer wall of one end of the heat dissipation plate groove 2. The telescopic electric cylinder 3 is equipped with a meshing component 4, which consists of a toothed plate and two gears meshing with it. Two protective covers 5 are also fixedly connected to the outer wall of one end of the heat dissipation plate groove 2. The plate body of the toothed plate and the two protective covers 5 are slidably connected through it. The bottom plate body of the toothed plate is fixedly connected to the movable end of the telescopic electric cylinder 3. Each of the two gears is fixedly connected with a rotating rod 6 that can be movably sleeved through the plate body of one end of the heat dissipation plate groove 2. The rods of the two rotating rods 6 are respectively connected to the two groove plates 7. One end plate is fixedly connected to the other end plate. Multiple elastic telescopic rings 8 are fixedly connected to the inner walls of the opposite ends of the two slot plates 7. The two sets of elastic telescopic rings 8 are respectively connected to the upper and lower meshes of the filter screen 9, and can be slidably connected to the mesh surface of the filter screen 9. T-shaped baffles 11 are respectively attached to the outer walls of the upper and lower ends of the two slot plates 7, and the plates of the two T-shaped baffles 11 are respectively slidably connected to the upper and lower end plates of the heat dissipation plate slot 2. Multiple springs 12 are also fixedly connected to the outer walls of the upper and lower end plates of the heat dissipation plate slot 2.

[0024] Using the above solution: By activating the telescopic electric cylinder 3 fixed on the heat dissipation plate slot 2, such as... Figure 2 and Figure 4As shown, the moving end of the gear causes the toothed plate in the meshing assembly 4 to move upward, thereby meshing and driving the two gears to rotate. This causes the rotating rod 6 and the slotted plate 7 to rotate in the same direction synchronously. The passive rotation of the two slotted plates 7, resulting in different tilt angles, directly affects the airflow for heat dissipation. The maximum passive tilt angle of the slotted plate 7 is 90 degrees. This causes the slotted plate 7 to change from its original vertical state to a horizontal state. The tilting of the two slotted plates 7 stretches and causes the filter screen 9 to tilt. The closer the tilt angle of the slotted plate 7 is to 90 degrees, the greater the passive tilting and bending angle of the filter screen 9. As the slotted plate 7 tilts, it will no longer continuously compress the T-shaped baffle 11 and the spring 12. At that time, the spring 12 will gradually recover its elasticity, causing the T-shaped baffle 11 to continue to adhere to the slotted plate 7 as it tilts, thus ensuring natural airflow for the intelligent system. During the heat dissipation process of the power distribution cabinet 1, the filter screen 9 will completely filter the filter. When the filter screen 9 is under tension, it will stretch the multiple elastic expansion rings 8 connected to its upper and lower sides, causing it to deform. When the slot plate 7 is passively reset, the multiple elastic expansion rings 8 can drive the filter screen 9 to reset. At this time, the plate opening of the slot plate 7 will have a flat scraping and dust removal effect on the surface of the filter screen 9. At this time, the dust attached to the filter screen 9 will be basically cleaned. At the same time, the filter screen 9 in the reset state will also be further cleaned by the soft bristle scraper 10 installed in the inner wall of the slot plate 7 to remove the dust stuck in its filter holes (when stretched and tilted, it will also be cleaned by the soft bristle scraper 10). The protective cover 5 can protect the tooth plate and gear when the meshing component 4 is meshing, and prevent debris from affecting the meshing between them.

[0025] The piston negative pressure structure includes an L-shaped plate 13. The bottom outer wall of the L-shaped plate 13 is fixedly connected to the top plate of the toothed plate. A T-shaped piston rod 14 is fixedly connected to the top outer wall of the L-shaped plate 13. A piston cylinder 15 is slidably connected to the upper part of the T-shaped piston rod 14. The outer wall of the piston cylinder 15 is fixedly connected to the outer wall of one end of the heat dissipation plate groove 2. An F-shaped suction pipe 16 and a special-shaped conveying pipe 17 are respectively fixedly connected through the two cylinders near the top of the piston cylinder 15. A one-way valve 18 is fixedly connected to the pipes of both the special-shaped conveying pipe 17 and the F-shaped suction pipe 16. The upper part of the straight pipe of the F-shaped suction pipe 16 is a rigid pipe, and the rest is a flexible pipe. A dust collection bucket is fixedly connected through the other two ends of the pipe of the F-shaped suction pipe 16, and the two dust collection buckets are respectively connected and tightly engaged with the plates of the two groove plates 7.

[0026] The above solution is adopted: such as Figure 3 and Figure 4As shown, the telescopic electric cylinder 3 drives the toothed plate to move up and down, and also drives the L-shaped plate 13 and the T-shaped piston rod 14 to move up and down in the piston cylinder 15, so that suction and compression forces are generated in its inner cavity. When the suction force occurs when it moves down, it mainly passes through the F-shaped suction pipe 16 and the dust collection buckets installed at both ends of the pipe to collect the dust that has been swept flat by the soft brush scraper 10 in the groove plate 7. The dust is then sucked into the piston cylinder 15. When the compression force is generated by the passive upward movement of the T-shaped piston rod 14, a small amount of dust in its inner cavity is discharged through the special-shaped conveying pipe 17. The one-way valve 18 installed on the F-shaped suction pipe 16 and the special-shaped conveying pipe 17 is used to ensure that the gas can only flow in one direction.

[0027] The rotary dehumidification structure includes two horizontal plates 19. Folding curtains 20 are fixedly connected to the upper and lower outer walls of both horizontal plates 19. A rectangular sliding groove is provided through the cabinet of the intelligent power distribution cabinet 1, allowing for fixed connection to each of the two sets of folding curtains 20. A U-shaped convex panel 21 is fixedly connected to one end of each of the two horizontal plates 19. A convex rotating wheel 22 is rotatably connected to the inner wall of each of the two U-shaped convex panels 21. A rotating rod 23 is fixedly connected through the convex rotating wheel 22. A double-ring sleeve rod is movably connected to the rod body of 23, and the bottom end of the double-ring sleeve rod is fixedly connected to the inner wall of the bottom end of the intelligent power distribution cabinet 1. A rotating cylinder 24 containing desiccant particles is fixedly connected to one end of the rotating rod 23. The cylinder body of the rotating cylinder 24 is made of a row of solid plates and a row of hollow mesh plates. Multiple support plates 25 are fixedly connected to the outer wall of the solid cylinder body of the rotating cylinder 24. Each support plate 25 has an absorbent cotton sleeve 26 for absorbing moisture fitted to its outer wall.

[0028] The above solution is adopted: such as Figure 4 , Figure 6 and Figure 7 As shown, the passive upward movement of the toothed plate can also drive the U-shaped convex panel 21 installed by the horizontal plate 19 to move upward, thereby driving the convex rotating wheel 22 to generate friction driving force, which drives the rotating rod 23 and the rotating cylinder 24 to rotate synchronously at a fixed point under the positioning of the double ring sleeve rod. The rotating cylinder 24 can drive multiple fixed support plates 25 and the absorbent cotton sleeve 26 sleeved on the support plates 25 to rotate. The rotating absorbent cotton sleeve 26 can absorb the moisture in the intelligent power distribution cabinet 1, avoiding the long-term damp environment that accelerates the insulation aging and metal corrosion of the power distribution structure in the cabinet, reducing maintenance costs and increasing service life. At the same time, the rotation of the support plate 25 will generate directional airflow, improve the efficiency of removing the accumulated hot air in the cabinet, avoid local overheating, and the absorbent cotton sleeve 26 is easy to disassemble and replace.

[0029] A humidity sensor 27 is fixedly connected to the other end of the rotating rod 23. The humidity sensor 27 is an HC2S3 industrial-grade humidity sensor with a measurement range of 0-100%RH, an accuracy of ±1.5%RH, and an operating temperature of -40~85℃. It has a built-in protective shell to adapt to different operating environments. A micro motor is fixedly connected to the other end of the rotating cylinder 24. A cylinder rod 28 is fixedly connected to the shaft of the micro motor. A long sliding rod 29 is rotatably connected to the inner wall of the cylinder rod 28. Two support cylinders 30 are fixedly connected to the long sliding rod 29. A curved solid plate 31 is fixedly connected to each of the two support cylinders 30. Each curved solid plate 31 is respectively attached to the inner wall of the area with the perforated mesh plate of the rotating cylinder 24. Multiple magnetic plates 32 are fixedly connected to the inner wall of the rotating cylinder 24 in a ring-like manner. Each solid plate 31 can be magnetically connected to each magnetic plate 32; soft rubber brush plates 33 are fixedly connected to the outer walls of both ends of the cylindrical rod 28. Both soft rubber brush plates 33 can intermittently slide and connect with the curved solid plate 31 and the magnetic plate 32. Two locking blocks 34 are fixedly connected to the rod body at both ends of one side of the long sliding rod 29. The inner walls of both ends of the cylindrical rod 28 are also provided with slots that can intermittently engage with the two sets of locking blocks 34. The two sets of locking blocks 34 can also intermittently rotate and connect with the inner wall of the cylindrical rod 28.

[0030] Using the above solution: When the humidity inside the intelligent power distribution cabinet 1 is too high, exceeding the set value, the humidity sensor 27 will output a signal to drive the micro motor, such as... Figure 8 and Figure 9 , Figure 10 As shown, the operating micro motor drives the cylinder rod 28 and the long slide rod 29 to rotate together. The direction of rotation is opposite to the passive rotation direction of the rotating cylinder 24. This causes the long slide rod 29 to drive multiple curved solid plates 31 fixed by the two support cylinders 30 to rotate inside the rotating cylinder 24. These plates directly contact the multiple magnetic plates 32 installed inside the rotating cylinder 24, causing magnetic attraction between the curved solid plates 31 and the magnetic plates 32. As the cylinder rod 28 continues to rotate passively, the presence of the magnetic plates 32 causes the slots in its inner wall to intermittently disengage from the locking blocks 34. As the cylinder rod 28 continues to rotate, it drives the soft rubber brush plates 33 fixed on the outer walls at both ends to rotate, thereby agitating the desiccant particles placed inside the rotating cylinder 24. This allows the particles to fully contact the gas inside the intelligent power distribution cabinet 1 through the perforated mesh, increasing the moisture adsorption effect inside the cabinet and achieving secondary adsorption.

[0031] One point to add is that the humidity sensor 27 typically consists of a sensing element and a signal processor, which can convert the physical quantity of humidity into an electrical signal output. It is specifically used to monitor the humidity inside the cabinet and convert these physical quantities of humidity into electrical signals, which are then used to control the operation of the micro motor.

[0032] The working principle and usage process of this invention are as follows: By activating the telescopic electric cylinder 3 fixed on the heat dissipation plate slot 2, the movable end of the telescopic electric cylinder 3 will drive the toothed plate in the meshing assembly 4 to move upward, thereby meshing and driving the two gears to rotate. This causes the two gears to synchronously drive the rotating rod 6 and the slot plate 7 to rotate in the same direction. The passive rotation of the two slot plates 7, resulting in different tilt angles, directly affects the airflow for heat dissipation. The maximum passive tilt angle of the slot plate 7 is 90 degrees. The closer the tilt angle of the slot plate 7 is to 90 degrees, the greater the passive tilting and bending angle of the filter screen 9. As the slot plate 7 tilts, it will no longer continuously compress the T-shaped baffle 11 and the spring 12. At that time, the spring... Spring 12 will gradually recover its elastic force, causing the plate of T-shaped baffle 11 to continue to adhere to the slot plate 7 as it tilts, thereby ensuring that the natural gas will be completely filtered by the filter screen 9. When the filter screen 9 is under tension, it will simultaneously stretch the multiple elastic telescopic rings 8 connected to its upper and lower sides. When the slot plate 7 is passively reset, the multiple elastic telescopic rings 8 can drive the filter screen 9 to reset. At this time, the opening of the slot plate 7 will produce a flat scraping and dust removal effect on the surface of the filter screen 9. At the same time, the filter screen 9 in the reset state will also be further cleaned by the soft bristle scraper 10 installed in the inner wall of the slot plate 7 to remove the dust stuck in its filter holes. The telescopic electric cylinder 3 drives the toothed plate to move up and down, and also drives the L-shaped plate 13 and the T-shaped piston rod 14 to move up and down in the piston cylinder 15, so that suction and squeezing forces are generated in its inner cavity. When the suction force occurs when it moves down, it mainly draws and collects the dust in the slot plate 7 through the F-shaped suction pipe 16 and the dust collection buckets installed at both ends of the pipe. The dust is then drawn into the piston cylinder 15. When the squeezing force is generated by the passive upward movement of the T-shaped piston rod 14, a small amount of dust in its inner cavity is discharged through the special-shaped conveying pipe 17. The one-way valve 18 installed on the F-shaped suction pipe 16 and the special-shaped conveying pipe 17 is used to achieve the effect that the gas can only flow in one direction. The passive upward movement of the toothed plate can also drive the U-shaped convex panel 21 installed by the horizontal plate 19 to move upward, thereby driving the convex rotating wheel 22 to generate friction driving force, which drives the rotating rod 23 and the rotating cylinder 24 to rotate synchronously at a fixed point under the positioning of the double ring sleeve rod. The rotating cylinder 24 can drive multiple fixed support plates 25 and the absorbent cotton sleeve 26 sleeved on the support plate 25 to rotate. Thus, the rotating absorbent cotton sleeve 26 can absorb the moisture in the intelligent power distribution cabinet 1. When the humidity inside the intelligent power distribution cabinet 1 is too high, exceeding the set value, the humidity sensor 27 outputs a signal to drive a micro motor. The operating micro motor drives the cylinder rod 28 and the long slide rod 29 to rotate together, in the opposite direction to the passive rotation of the rotating drum 24. This causes the long slide rod 29 to rotate multiple curved solid plates 31 fixed by two support cylinders 30 inside the rotating drum 24, directly contacting multiple magnetic plates 32 installed inside the rotating drum 24. This causes magnetic attraction between the curved solid plates 31 and the magnetic plates 32, causing the curved solid plates 31 to detach from the seal on the perforated mesh plate on the rotating drum 24. Due to the obstruction of the magnetic plates 32, the slots in their inner walls intermittently disengage and engage with the locking blocks 34. Thus, the continuous rotation of the cylinder rod 28 drives the soft rubber brush plates 33 fixed on the outer walls at both ends to rotate, thereby agitating the desiccant particles placed inside the rotating drum 24, allowing them to fully contact the gas inside the intelligent power distribution cabinet 1 through the perforated mesh plate.
