Description

Technical Field

[0001] This invention relates to the field of smart grid outdoor distribution cabinet technology, specifically a rainproof and energy-saving outdoor distribution cabinet. Background Technology

[0002] Outdoor power distribution cabinets are electrical protection and distribution devices specifically designed for open-air environments. They are typically made of corrosion-resistant materials such as cold-rolled steel plates, 304 or 316 stainless steel, and are widely used in various outdoor power supply scenarios such as municipal roads, industrial parks, residential communities, and construction sites to ensure the stability and safety of end-user power. They usually feature a sloping, diversion-type rain cover on top to quickly drain accumulated water, and sealant and waterproof cable joints at the cabinet seams to block moisture intrusion. An independent air dehumidification chamber and waterproof ventilation valve are added inside to resolve the conflict between dust prevention and heat dissipation.

[0003] Application CN115459071A discloses a rainwater transfer device on the baffle plate; heat dissipation vents on both sides of the cabinet, each heat dissipation vent having a water-blocking device on the side near the inner cavity, and the water-blocking device being controlled to close by the rainwater transfer device; wiring devices are also provided on both sides of the cabinet, the wiring devices including liquid cooling components connected to the rainwater transfer device, the technical effect being that it has the advantage of controlling the opening and closing of the heat dissipation vents by rainwater, and simultaneously dissipating heat from the wires when the heat dissipation vents are closed.

[0004] Application CN204045966U discloses an outdoor waterproof distribution cabinet. The inner door panel has an inspection port at its center, and an annular vacuum groove is formed on the side of the inner door panel opposite to the cabinet door. The inspection port is located at the center of the annular vacuum groove. A sealing plate is provided on the side of the cabinet door opposite to the inner door panel to simultaneously seal the inspection port and the annular vacuum groove. Sealing rubber is fixedly provided on the side of the sealing plate opposite to the inner door panel, and the inner door panel is bolted to the sealing plate. A vacuum pump is installed inside the cabinet, and the vacuum pump's suction port is connected to the annular vacuum groove. This design is suitable for outdoor waterproof distribution cabinets.

[0005] However, the aforementioned rainproof outdoor distribution cabinets still have the following problems in actual use: the water-blocking components protect the distribution cabinet from rainwater entering the cabinet and affecting the operation of the power distribution components. The existing water-blocking components can achieve a sealing effect in rainy weather, but they cannot effectively utilize rainwater during the normal operation of the distribution cabinet. The heat generated by the power distribution components inside the cabinet cannot be effectively channeled through the water-blocking components. At the same time, the heat dissipation area of ​​some distribution cabinets cannot be blocked in rainy weather, allowing rainwater to enter the cabinet, increasing humidity and affecting the normal operation of the power distribution components.

[0006] Therefore, we proposed a rainproof and energy-saving outdoor power distribution cabinet to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a rainproof and energy-saving outdoor power distribution cabinet. This invention addresses the problem that while existing water-blocking components can achieve a sealing effect in rainy conditions, they cannot effectively utilize rainwater during normal operation of the power distribution cabinet. Furthermore, the heat generated by the power distribution components inside the cabinet cannot be effectively channeled through the rubber rings by the water-blocking components. Additionally, some power distribution cabinets have heat dissipation areas that cannot be blocked in rainy weather, allowing rainwater to enter the cabinet, increasing humidity and affecting the normal operation of the power distribution components.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rainproof and energy-saving outdoor power distribution cabinet, comprising a power distribution cabinet body and power distribution components installed inside the power distribution cabinet body, wherein heat dissipation grilles are provided on both the left and right sides inside the power distribution cabinet body. The top of the power distribution cabinet body is provided with a power consumption reduction mechanism, and the power consumption reduction mechanism includes a water collection top plate, and a water collection cavity is opened at the center of the water collection top plate. The energy-saving mechanism includes heat exchange coils, which are distributed symmetrically in front and behind, and are installed inside the upper part of the distribution cabinet body. The power distribution cabinet body is equipped with rainproof mechanisms on the left and right sides of the exterior, and the rainproof mechanisms include rainproof frames, and a heat dissipation window is opened at the center of the exterior of the rainproof frames.

[0009] Preferably, the water collection top plate included in the energy-saving mechanism is fixedly installed at the center of the top surface of the power distribution cabinet body, and the bottom surface of the water collection top plate is larger than the top surface of the power distribution cabinet body, and heat exchange slots are opened on both the left and right sides inside the water collection top plate.

[0010] Preferably, the upper end of the heat exchange coil included in the energy-saving mechanism is connected to the inside of the heat exchange slot, and the lower end of the heat exchange coil is disposed on the left and right sides of the outside of the power distribution cabinet body. The heat exchange coil is used to guide the low-level rainwater in the water collection cavity inside the water collection top plate to the inside of the power distribution cabinet body, absorb the heat of the power distribution components, and then discharge it to the outside of the power distribution cabinet body.

[0011] Preferably, the top of the water collection plate is provided with a drainage mechanism, and the drainage mechanism includes a filter sealing plate. The filter sealing plate is fixedly installed on the outside of the top surface of the water collection cavity inside the water collection plate. A drainage scraper is attached to and slides on the outside of the top surface of the filter sealing plate, and the lower end of the drainage scraper is attached to and slides on the outer wall of the water collection plate.

[0012] Preferably, the dredging mechanism includes a reciprocating screw, which is rotatably mounted behind the bottom surface of the water collection top plate via a bearing, and the reciprocating screw is threadedly connected to the lower rear end of the dredging scraper. Furthermore, the left and right ends of the reciprocating screw are meshed with the upper end of the bidirectional screw via a main bevel gear set.

[0013] Preferably, the rain-blocking mechanism includes a rain-blocking baffle, which is fixedly installed on the left and right sides inside the water collection top plate. A buoyancy plate is slidably connected to the inner side of the rain-blocking baffle. Overflow slots are provided at the lower inner side of the buoyancy plate and the upper inner side of the rain-blocking baffle. At the same time, anti-clogging fork blocks are fixedly installed at equal intervals on the top of the buoyancy plate near the rain-blocking baffle.

[0014] Preferably, the rain-blocking mechanism includes an overflow transverse groove, which is opened on the left and right sides inside the water collection top plate and is connected to the water collection cavity. The overflow transverse groove is rotatably connected to a drive water wheel through a torsion spring, and the rear end shaft of the drive water wheel extends into the interior of the water collection top plate.

[0015] Preferably, the rear end of the drive water wheel included in the rain-blocking mechanism is connected to the upper end of the bidirectional lead screw through a set of secondary bevel teeth, and the lower end of the bidirectional lead screw is rotatably mounted inside the rear of the rain-blocking frame through a bearing. The rain-blocking frame is fixedly installed on the left and right sides of the outside of the power distribution cabinet body, and the heat dissipation windows and heat dissipation grilles opened inside the rain-blocking frame are correspondingly distributed.

[0016] Preferably, the rain-blocking mechanism includes a rain-blocking slide plate, which is slidably installed on the upper and lower sides of the rain-blocking frame in a vertically symmetrical manner. The rear end of the rain-blocking slide plate is threadedly connected to a bidirectional lead screw at the rear of the rain-blocking frame. In the initial state, the rain-blocking slide plates are distributed on the upper and lower sides of the rain-blocking frame in a vertically distancing manner.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: This rainproof and energy-saving outdoor power distribution cabinet distinguishes different rainfall amounts through a water collection plate on the top of the cabinet body, introducing some rainwater into the cabinet body to achieve heat exchange. A guide scraper slides back and forth to prevent blockage, while a rainproof sliding plate seals the heat dissipation grille to prevent rainwater seepage during heavy rainfall, reducing energy consumption and ensuring the normal operation of the power distribution components. The specific details are as follows: 1. The water collection top plate is fixedly installed at the center of the top surface of the distribution cabinet. The rainwater accumulated inside the water collection cavity is introduced into the heat exchange coil through the heat exchange slot holes. After the filter plate filters the rainwater, the rainwater flows along the S-shaped path of the heat exchange coil through the upper part of the distribution cabinet. It continuously absorbs the heat generated by the operation of the power distribution components and is discharged from the lower end of the coil, directly reducing the operating temperature rise inside the distribution cabinet. There is no additional energy consumption output throughout the process, realizing the passive energy saving effect of outdoor distribution cabinet.

[0018] 2. The buoyancy plate, which is slidably connected to the inner side of the rainproof baffle, rises synchronously with the water level inside the water collection chamber. When the buoyancy plate slides above the rainproof baffle, the overflow slots distributed above and below automatically connect coaxially. Excess rainwater inside the water collection chamber is discharged outward through the overflow slots. The anti-clogging fork block fixed at the top of the buoyancy plate moves synchronously against the inner wall of the rainproof baffle as it rises, continuously forking and guiding debris inside the overflow slots, preventing water from overflowing and backflowing inside the water collection chamber during heavy rainfall.

[0019] 3. The rainwater flowing inside the overflow trough drives the water wheel to rotate, which in turn drives the bidirectional screw to rotate through the secondary bevel gear group. The upper end of the bidirectional screw drives the reciprocating screw to rotate synchronously through the main bevel gear group. The threaded guide scraper slides along the top surface of the filter sealing plate in full-width reciprocating motion. The guide scraper moves in close contact with the surface of the filter sealing plate throughout the entire process, continuously scraping away and cleaning the attached dirt.

[0020] 4. When the bidirectional lead screw rotates, it drives the symmetrically distributed rainproof slide plates to slide synchronously inward along the inside of the rainproof frame. After the inner ends of the two rainproof slide plates are completely in contact, the heat dissipation window is completely sealed. The drive water wheel always maintains a one-way locked state during the continuous flow of rainwater, completely avoiding the rainproof slide plates from opening in reverse due to the rebound of the torsion spring. Under heavy rainfall conditions, it automatically completes the full sealing protection of the heat dissipation window, completely blocking the path of external rainwater to enter the inside of the power distribution cabinet through the heat dissipation grille, and maintaining a dry operating environment for the power distribution components throughout the process.

[0023] 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.

[0024] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problems existing in the use of existing outdoor power distribution cabinets, this example discloses the following technical solution: a rainproof and energy-saving outdoor power distribution cabinet, including a power distribution cabinet body 1 and power distribution components 2 installed inside the power distribution cabinet body 1. Heat dissipation grilles 3 are provided on both the left and right sides inside the power distribution cabinet body 1. A energy-saving mechanism is provided on the top of the power distribution cabinet body 1, and the energy-saving mechanism includes a water collection top plate 4, with a water collection cavity 5 located at the center of the water collection top plate 4. The energy-saving mechanism includes heat exchange coils 6, which are distributed symmetrically front and back, and the heat exchange coils 6 penetrate through the upper part of the interior of the power distribution cabinet body 1.

[0025] The energy-saving mechanism includes a water collection plate 4, which is fixedly installed at the center of the top surface of the distribution cabinet body 1. The bottom surface of the water collection plate 4 is larger than the top surface of the distribution cabinet body 1. Heat exchange slots 9 are provided on both the left and right sides inside the water collection plate 4. The upper end of the heat exchange coil 6 included in the energy-saving mechanism is connected to the inside of the heat exchange slot 9, and the lower end of the heat exchange coil 6 is provided on the left and right sides outside the distribution cabinet body 1. The heat exchange coil 6 is used to guide the low-level rainwater in the water collection cavity 5 inside the water collection plate 4 to the inside of the distribution cabinet body 1, absorb the heat of the power distribution components 2, and then discharge it to the outside of the distribution cabinet body 1.

[0026] like Figures 1-3As shown, the power distribution cabinet body 1 is used to load and position the power distribution component 2. The cover plate on the front of the power distribution cabinet body 1 protects the power distribution component 2, thereby preventing rainwater from entering and interfering with outdoor power distribution operation. At the same time, the heat dissipation grilles 3 on the left and right sides of the power distribution cabinet body 1 correspond to the heat exhaust windows 8 inside the rainproof outer frame 7, so that the heat dissipated by the power distribution component 2 during operation can flow through the heat dissipation grilles 3 and heat exhaust windows 8, thereby ensuring the normal operation of the power distribution component 2.

[0027] Furthermore, during rainy weather, rainwater is collected by the water collection cavity 5 inside the water collection top plate 4. The sealing filter plate 10 on the top surface of the water collection top plate 4 filters the rainwater, removing impurities. After a small amount of rainwater enters the water collection cavity 5, it is guided to the heat exchange coil 6 through the heat exchange slots 9. The rainwater flows in an "S" shape after entering the heat exchange coil 6. The heat exchange coil 6 is located above the inside of the distribution cabinet body 1, thereby exchanging heat with the upper part of the distribution cabinet body 1 and flowing to the lower end of the heat exchange coil 6 for discharge, achieving a heat exchange and energy saving effect under light rain conditions.

[0028] Example 2: To solve the problems existing in the use of existing outdoor power distribution cabinets, this example discloses the following technical solution: The rainproof mechanism includes a rainproof partition 15, which is fixedly installed on the left and right sides inside the water collection top plate 4. A buoyancy horizontal plate 16 is slidably connected to the inner side of the rainproof partition 15. Overflow slots 17 are opened at the lower part of the inner side of the buoyancy horizontal plate 16 and the upper part of the inner side of the rainproof partition 15. At the same time, anti-blocking fork blocks 18 are fixedly installed at equal distances on the top side of the buoyancy horizontal plate 16 near the rainproof partition 15. The overflow horizontal groove 19 is connected to the water collection cavity 5 through the overflow horizontal groove 19. A drive water wheel 20 is rotatably connected to the inside of the overflow horizontal groove 19 through a torsion spring. The rear end shaft of the drive water wheel 20 extends into the inside of the water collection top plate 4.

[0029] The rear end of the drive water wheel 20 included in the rain-blocking mechanism is connected to the upper end of the double-acting screw 14 through the meshing of the secondary bevel gear group 21, and the lower end of the double-acting screw 14 is rotatably mounted inside the rear of the rain-blocking frame 7 through the bearing. The rain-blocking frame 7 is fixedly installed on the left and right sides of the outside of the power distribution cabinet body 1, and the heat dissipation window 8 and the heat dissipation grille 3 are correspondingly distributed inside the rain-blocking frame 7.

[0030] like Figures 6-8As shown, when there is heavy rainfall, if the water collection cavity 5 inside the water collection top plate 4 cannot effectively discharge rainwater through the heat exchange slots 9, the rainwater will first accumulate through the rain-blocking baffle 15. During the accumulation process, the water level will rise, and the rainwater will drive the buoyancy plate 16 to move upward synchronously. After the buoyancy plate 16 slides upward to above the rain-blocking baffle 15, the overflow slots 17 distributed vertically will be coaxially connected, allowing the rainwater inside the water collection top plate 4 to flow outward through the overflow slots 17. At the same time, when the buoyancy plate 16 rises, it will drive the anti-blocking fork block 18 at the top to move against the rain-blocking baffle 15, thereby clearing the overflow slots 17 inside the rain-blocking baffle 15 and preventing rainwater from blocking the overflow slots 17 and affecting the discharge of rainwater inside the water collection top plate 4.

[0031] The top of the water collection plate 4 is provided with a guiding mechanism, which includes a filter top plate 10. The filter top plate 10 is fixedly installed on the outside of the top surface of the water collection cavity 5 inside the water collection plate 4. A guiding scraper 11 is slidably attached to the outside of the top surface of the filter top plate 10, and the lower end of the guiding scraper 11 is attached to and slidably attached to the outer wall of the water collection plate 4. The guiding mechanism includes a reciprocating screw 12, which is rotatably installed behind the bottom surface of the water collection plate 4 through a bearing. The reciprocating screw 12 is threadedly connected to the lower rear end of the guiding scraper 11, and the left and right ends of the reciprocating screw 12 are meshed with the upper end of the bidirectional screw 14 through a main bevel gear set 13.

[0032] like Figures 9-10 As shown, when rainwater flows through the overflow slot 17 inside the water collection top plate 4, it flows downward through the overflow transverse slots 19 opened on the left and right sides of the water collection top plate 4, and drives the drive water wheel 20 inside the overflow transverse slot 19 to rotate. The drive water wheel 20 drives the meshing bidirectional lead screw 14 to rotate through the secondary bevel gear group 21, and the bidirectional lead screw 14 drives the meshing reciprocating lead screw 12 to rotate through the main bevel gear group 13. Thus, the reciprocating lead screw 12 drives the threaded guide scraper 11 to move left and right. At the same time, the moving guide scraper 11 cleans the filter top plate 10 during movement, thereby preventing the debris in the rainwater from clogging the filter top plate 10 and affecting the subsequent rainwater collection.

[0033] Example 3: In order to solve the problems existing in the use of existing outdoor power distribution cabinets, this example discloses the following technical solution: the power distribution cabinet body 1 is provided with rainproof mechanisms on the left and right sides of the exterior, and the rainproof mechanism includes a rainproof frame 7, and a heat dissipation window 8 is opened at the center of the exterior of the rainproof frame 7; the rainproof mechanism includes a rainproof sliding plate 22, and the rainproof sliding plate 22 is slidably installed on the upper and lower sides of the interior of the rainproof frame 7 in a vertically symmetrical manner, and the rear end of the rainproof sliding plate 22 is threadedly connected to the bidirectional lead screw 14 at the rear of the interior of the rainproof frame 7, and the rainproof sliding plate 22 in the initial state is distributed on the upper and lower sides of the interior of the rainproof frame 7 in a vertically away manner.

[0034] like Figures 3-5 As shown, during the rotation of the double-acting screw 14 driven by the drive water wheel 20 on the left and right sides inside the water collection top plate 4, the rainproof sliding plate 22 threadedly connected to the double-acting screw 14 is limited by the rainproof outer frame 7, so that the rotating double-acting screw 14 drives the rainproof sliding plate 22 threadedly connected on the upper and lower sides to slide inward synchronously, so that the rainproof sliding plate 22 on the upper and lower sides come into contact with each other at the inner end and stop, and close the heat dissipation window 8 opened inside the rainproof outer frame 7, thereby preventing rainwater from entering the interior of the power distribution cabinet body 1 through the heat dissipation grille 3 during heavy rain and affecting the normal operation of the power distribution components 2.

[0035] Furthermore, when the rain-blocking sliding plates 22 on the upper and lower sides inside the rain-blocking outer frame 7 are in contact with each other, the bidirectional lead screw 14 connected to its rear end and the drive water wheel 20 are in a stationary state. The rainwater flowing through the overflow transverse groove 19 inside the water collection top plate 4 can no longer drive the drive water wheel 20 to rotate, but always provides a locking force in one direction to the drive water wheel 20, thereby preventing the drive water wheel 20 connected by the torsion spring from rotating in the opposite direction and opening the heat dissipation window 8, causing rainwater to enter.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
