Abstract

This invention discloses a gravity capillary drainage waterproof outdoor power distribution box, belonging to the field of smart grid technology. It includes a power distribution box body, and the current collection mechanism includes a current-collecting hood fixedly connected to the bottom surface of the power distribution box body. This invention, through the setting of a guide seat, an upper capillary tube, a side capillary tube, and a lower capillary tube, guides condensate water through the inclined surface at the bottom of the guide seat, converging it at the lowest point and dripping it into the upper capillary tube. The upper, side, and lower capillary tubes sequentially receive and transfer the water downwards, allowing the condensate water to flow downwards along a predetermined drainage path. This device can actively collect and directionally drain condensate water generated inside the power distribution box due to the breathing effect, as well as rainwater seeping in from gaps, solving the technical problems of existing power distribution boxes where condensate water and seeping water cannot be actively collected and directionally discharged, easily causing water accumulation at the bottom of the box and equipment corrosion.

Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and in particular to a gravity capillary drainage water collection chamber waterproof outdoor distribution box. Background Technology

[0002] Outdoor distribution boxes, as key equipment for power distribution and control, are widely deployed in open environments such as urban roads, industrial parks, residential areas, and along power transmission lines in the wild. Due to long-term exposure to natural climate conditions, distribution boxes face multiple water damage threats such as rainwater erosion, moisture penetration, and condensation. The electrical components installed inside, such as circuit breakers, contactors, and control boards, are extremely sensitive to humid environments. Once water enters or becomes damp, it can cause short circuits and equipment corrosion, or even power supply accidents or electrical fires.

[0003] For example, an outdoor waterproof distribution box with application number "CN202022095004.6" includes a box body. A rectangular opening is formed on one side of the box body, and a rectangular frame is welded inside the opening. A groove is provided on the inner wall of one side of the frame, and a spring is connected to the bottom surface of the groove. The end of the spring is connected to a pressing block movably connected to the groove, with the outer end of the pressing block extending out of the groove. A telescopic airbag is also provided between the inner end of the pressing block and the bottom of the groove. A door panel is installed inside the frame, and the side of the door panel away from the groove is rotatably connected to the opposite side walls of the frame via a pin. A hollow sealing ring is provided on the inner side of the frame without the groove. A second air chamber communicating with the telescopic airbag is provided inside the frame, and a first air chamber communicating with the inside of the sealing ring is also provided inside the frame. The first and second air chambers are internally connected. This utility model has a simple structure, and when the door panel is closed, it has good sealing performance with the frame, providing a certain degree of waterproofing.

[0004] Based on the aforementioned existing technologies, current waterproofing methods generally involve installing rubber sealing strips between the box door and the box body, and installing waterproof connectors at cable entry and exit points to improve the overall sealing level of the distribution box casing. However, sealing strips are prone to aging, deformation, and loss of elasticity during long-term use. Combined with wear caused by frequent opening and closing of the box door, the sealing performance significantly decreases over time. Simultaneously, the box body experiences a "breathing effect" due to diurnal temperature variations; when the temperature rises, the air inside the box expands and is expelled, while when the temperature drops, humid external air is drawn in. Moisture condenses inside the box upon cooling, accumulating at the bottom and unable to escape naturally. Alternatively, ventilation louvers can be installed on the side walls of the distribution box, or axial fans can be installed to promote air convection and reduce internal humidity. However, this method presents a dilemma: if the ventilation openings are too small, the dehumidification effect is poor; if the openings are too large, external rainwater and dust can easily intrude. Even with dust filters, if the filters become clogged and not cleaned promptly, ventilation can worsen, and rainwater can still seep into the box through the gaps in the louvers during windy and rainy weather. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing sealing strips are prone to aging, deformation, and loss of elasticity during long-term use, and the sealing performance significantly decreases over time due to wear caused by frequent opening and closing of the box door. Simultaneously, the box exhibits a "breathing effect" under diurnal temperature variations; that is, when the temperature rises, the air inside the box expands and is expelled, and when the temperature drops, humid external air is drawn in. Moisture condenses inside the box upon cooling, accumulating at the bottom and unable to drain naturally. Therefore, this invention proposes a gravity capillary drainage water collection chamber waterproof outdoor electrical distribution box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A gravity capillary drainage water collection chamber waterproof outdoor distribution box includes: A power distribution box, wherein a current collecting mechanism is fixedly connected to the bottom end of the power distribution box, the current collecting mechanism includes a current collecting cover fixedly connected to the bottom end surface of the power distribution box, and a current collecting pipe is fixedly connected to the bottom end of the current collecting cover; A flow guide mechanism is fixedly connected to the inner side of the distribution box. The flow guide mechanism includes two flow guide seats fixedly connected to the top surface inside the distribution box. The bottom end of the flow guide seat is inclined. An inclined upper capillary tube is fixedly connected to the bottom end of the flow guide seat. A side capillary tube is fixedly connected to the bottom end of the upper capillary tube. A lower capillary tube is also fixedly connected to the bottom end of the side capillary tube. The lower capillary tube is laid inside the flow hood. Drainage grooves are opened inside the lower capillary tube, the side capillary tube, and the upper capillary tube. Airflow guide holes adapted to the drainage grooves are opened inside the drainage grooves.

[0007] Preferably, the upper capillary tube, the side capillary tube, and the lower capillary tube are all used to supply water to the interior of the flow-collecting hood. An internal filter element is fixedly connected inside the flow-collecting pipe. The internal filter element is used to filter the water entering the flow-collecting pipe. An auxiliary flow mechanism is fixedly connected to the outside of the distribution box.

[0008] Preferably, the auxiliary flow mechanism includes an air inlet end seat fixedly connected to the outer wall of the distribution box. There are two air inlet end seats, which are symmetrically fixedly connected to the left and right sides of the distribution box. A waterproof filter element is fixedly connected to the air inlet end seat. The waterproof filter element is used to isolate external water vapor from entering the distribution box.

[0009] Preferably, the auxiliary flow mechanism further includes a dust baffle fixedly connected to one end of the air intake seat. The dust baffle is located at the outer end of the waterproof filter element. The dust baffle is used to prevent external dust from entering the air intake seat. A connecting tube is fixedly connected in a linear array on the side of the air intake seat away from the dust baffle. The connecting tube communicates with the air intake seat and is used to communicate with the airflow guide hole.

[0010] Preferably, a slag removal mechanism is installed at the front end of the distribution box. The slag removal mechanism includes a maintenance baffle fixedly connected to the front end of the distribution box. The maintenance baffle is connected to the distribution box by a fixing bolt. A heat exchange baffle is arranged in a rectangular array on the front surface of the maintenance baffle. An inclined slag removal pipe is also fixedly connected to the inner side of the maintenance baffle. A rainproof canopy is fixedly connected to the top of the distribution box. A closed box door is installed at the front end of the distribution box. A power distribution module is also fixedly connected to the inner side of the distribution box.

[0011] Preferably, the bottom end of the slag removal pipe is provided with an opening that extends into the inner side of the flow-gathering hood. The slag removal mechanism also includes a slag discharge pipe fixedly connected to the bottom end of the outer wall of the slag removal pipe, a servo motor fixedly connected to one end of the slag removal pipe, and a slag discharge auger fixedly connected to the output shaft of the servo motor.

[0012] Preferably, the slag discharge auger is rotatably connected to the inner side of the slag removal pipe and is driven to rotate by a servo motor. When the slag discharge auger is driven to rotate by the servo motor, the waste slag deposited inside the flow hood is discharged through the slag discharge pipe.

[0013] Preferably, a drainage mechanism is fixedly connected to the bottom end of the manifold, the drainage mechanism including a connecting pipe fixedly connected to the bottom end of the manifold, a drainage sleeve rotatably connected to the bottom end of the connecting pipe, and a drainage base fixedly connected to the bottom end of the inside of the drainage sleeve.

[0014] Preferably, the drainage mechanism further includes a drainage port arranged in a ring array at the bottom of the drainage base, a quick-drain magnetic ring fixedly connected to the top of the drainage base, and a return spring fixedly connected to the top of the drainage base.

[0015] Preferably, a magnetic support is fixedly connected to the top end of the return spring. The magnetic support is adapted to the quick-release magnetic ring. When the quick-release magnetic ring is energized and generates magnetism, the magnetic support is in a state of synchronous descent due to magnetic attraction. A sealing piston for sealing the top opening of the drain sleeve is fixedly connected to the top end of the magnetic support. A dust cover is fitted on the outside of the return spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by setting up components such as a flow guide seat, an upper capillary tube, a side capillary tube, and a lower capillary tube, the condensate is guided and collected at the lowest point by the inclined surface at the bottom of the flow guide seat and then drips into the upper capillary tube. The upper, side, and lower capillary tubes sequentially receive and transfer the water downwards, so that the condensate can flow downwards step by step along a predetermined drainage path. This can actively collect and directionally drain the condensate generated inside the distribution box due to the breathing effect and the rainwater seeping in from the gaps, solving the technical problem that the existing distribution box cannot actively collect and directionally drain the condensate and seeping water inside, which easily causes water accumulation at the bottom of the box and equipment corrosion.

[0017] 2. In this invention, a waterproof filter element intercepts and filters the moisture in the humid air entering the air intake seat. Dry air is delivered to the airflow guide hole through a connecting tube. The dry air is blown along the inner wall of the drainage groove through the airflow guide hole. The airflow thrust accelerates the flow speed of condensate along the drainage groove and evaporates and carries away the residual moisture. This device can accelerate the discharge of condensate by utilizing the dual effects of natural gravity and airflow assistance without relying on an external power source. This solves the technical problem that condensate inside the existing distribution box cannot be discharged in time due to the lack of active delivery power.

[0018] 3. In this invention, the filtered water is buffered by a drainage sleeve, and gravity self-drainage is achieved by the natural opening of the sealing piston through water pressure. Forced drainage is achieved by the magnetic attraction force generated by the energized quick-draining magnetic ring, which actively drives the magnetic support and sealing piston to move downward. After the power is cut off, the return spring pushes the magnetic support and sealing piston upward to restore the sealing state. This device can achieve automatic gravity drainage by water pressure under normal conditions, and actively drain water by energizing it when there is severe water accumulation. This avoids the technical problems of existing drainage structures that are not smooth when the water volume is small or when there is debris, and that rely entirely on manual operation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figure 1 - Figure 9 A gravity capillary drainage water collection chamber waterproof outdoor power distribution box, comprising: The distribution box 1 has a current collecting mechanism fixedly connected to its bottom end. The current collecting mechanism includes a current collecting cover 6 fixedly connected to the bottom end surface of the distribution box 1, and a current collecting pipe 601 fixedly connected to the bottom end of the current collecting cover 6. A flow guide mechanism is fixedly connected to the inner side of the distribution box 1. The flow guide mechanism includes two flow guide seats 3 fixedly connected to the top surface inside the distribution box 1. The bottom end of the flow guide seat 3 is inclined. An inclined upper capillary tube 301 is fixedly connected to the bottom end of the flow guide seat 3. A side capillary tube 3011 is fixedly connected to the bottom end of the upper capillary tube 301. A lower capillary tube 3014 is also fixedly connected to the bottom end of the side capillary tube 3011. The lower capillary tube 3014 is laid inside the flow collector hood 6. Drainage grooves 3012 are opened inside the lower capillary tube 3014, the side capillary tube 3011, and the upper capillary tube 301. The drainage grooves 3012 are connected to the drainage grooves 3013 and 3014. The airflow guide hole 3013 is adapted to phase 012, so the multi-stage directional drainage function of condensate and seepage water inside the distribution box allows the condensate to be guided step by step through the upper capillary tube 301, the side capillary tube 3011 and the lower capillary tube 3014, and finally all of them flow into the flow-collecting hood 6 and the collection pipe 601, ensuring that there is no water residue in the box. The upper capillary tube 301, the side capillary tube 3011 and the lower capillary tube 3014 are all used to supply water to the inside of the flow-collecting hood 6. The inside of the collection pipe 601 is fixedly connected to the built-in filter element 6011, which is used to filter the water entering the collection pipe 601. The outside of the distribution box 1 is fixedly connected to the auxiliary flow mechanism.

[0023] Furthermore, the auxiliary flow mechanism includes an air inlet end seat 2 fixedly connected to the outer wall of the distribution box 1. Two air inlet end seats 2 are provided, symmetrically fixedly connected to the left and right sides of the distribution box 1. A waterproof filter element 201 is fixedly connected to the air inlet end seat 2, used to isolate external moisture from entering the distribution box 1. The auxiliary flow mechanism also includes a dustproof baffle 2011 fixedly connected to one end of the air inlet end seat 2. The dustproof baffle 2011 is located at the outer end of the waterproof filter element 201, used to prevent external dust from entering the air inlet end seat 2. A connecting tube 2012 is fixedly connected in a linear array to the side of the air inlet end seat 2 away from the dustproof baffle 2011. The connecting tube 2012 communicates with the air inlet end seat 2 and is used to connect with the airflow guide hole 3013. The through-connection enables unified collection and filtration purification of water, ensuring that the water supplied to the flow-collecting hood 6 by the capillary tube is effectively filtered by the built-in filter element 6011 before entering the collection pipe 601, thus ensuring the cleanliness and unobstructed flow of the drainage pipe. A slag removal mechanism is installed at the front end of the distribution box 1. The slag removal mechanism includes a maintenance baffle 4 fixedly connected to the front end of the distribution box 1. The maintenance baffle 4 is connected to the distribution box 1 by a fixing bolt 4011. A heat exchange baffle 401 is arranged in a rectangular array on the front end face of the maintenance baffle 4. An inclined slag removal pipe 5 is also fixedly connected to the inner side of the maintenance baffle 4. A rainproof canopy 101 is fixedly connected to the top of the distribution box 1. A closed box door 1011 is installed at the front end of the distribution box 1. A power distribution module 1012 is also fixedly connected to the inner side of the distribution box 1.

[0024] Furthermore, the bottom end of the slag removal pipe 5 is provided with an opening that extends into the inner side of the flow-gathering hood 6. The slag removal mechanism also includes a slag discharge pipe 501 fixedly connected to the bottom end of the outer wall of the slag removal pipe 5, a servo motor 5011 fixedly connected to one end of the slag removal pipe 5, and a slag discharge auger 5012 fixedly connected to the output shaft of the servo motor 5011. This completes the water vapor isolation function for the external air intake, so that the airflow entering the distribution box 1 through the air intake end seat 2 is filtered by the waterproof filter element 201 to ensure that the air entering the box is in a dry state. The slag discharge auger 5012 is rotatably connected to the inner side of the slag removal pipe 5 and is driven to rotate by the servo motor 5011. When the slag discharge auger 5012 is driven to rotate by the servo motor 5011, the waste slag deposited inside the flow-gathering hood 6 is discharged through the slag discharge pipe 501.

[0025] Furthermore, a drainage mechanism is fixedly connected to the bottom end of the manifold 601. The drainage mechanism includes a connecting pipe 7 fixedly connected to the bottom end of the manifold 601, a drainage sleeve 701 rotatably connected to the bottom end of the connecting pipe 7, and a drainage base 7011 fixedly connected to the bottom end of the drainage sleeve 701. The drainage mechanism also includes drainage ports 7012 arranged in a ring array at the bottom of the drainage base 7011, a quick-drain magnetic ring 7013 fixedly connected to the top end of the drainage base 7011, and a return spring 7016 fixedly connected to the top end of the drainage base 7011. This achieves the dual function of directional airflow introduction and dust blocking, allowing external air to pass sequentially through the dustproof baffle 2011. After dual filtration with the waterproof filter element 201, the water is transported to the drainage tank 3012 through the connecting tube 2012 and the airflow guide hole 3013, which accelerates the evaporation and discharge efficiency of the water in the drainage tank 3012. The top of the return spring 7016 is fixedly connected to a magnetic support 7014. The magnetic support 7014 is compatible with the quick-discharge magnetic ring 7013. When the quick-discharge magnetic ring 7013 is energized and generates magnetism, the magnetic support 7014 is in a state of synchronous descent under magnetic attraction. The top of the magnetic support 7014 is fixedly connected to a sealing piston 7015 for sealing the top opening of the drainage sleeve 701. The outside of the return spring 7016 is covered with a dust cover 7017.

[0026] In use, first, the distribution box 1 is installed in the outdoor preset position through the current gathering cover 6 and the current collecting pipe 601 at its bottom. The closed box door 1011 is kept closed with the distribution box 1. The power distribution module 1012 runs normally inside the distribution box 1. The rainproof canopy 101 provides rain protection for the top of the distribution box 1. Then, when the temperature difference between day and night causes a breathing effect inside the distribution box 1, the external humid air enters the distribution box 1 through the air inlet seat 2. The water vapor in the humid air is intercepted and filtered when it flows through the waterproof filter element 201. The dry air enters the drainage groove 3012 through the connecting tube 2012. The dust baffle 2011 at the outer end of the air inlet seat 2 blocks the external dust outside the air inlet seat 2, realizing the double protection filtration of the air inlet seat 2. When the temperature inside the distribution box 1 changes further, the residual water vapor in the box condenses into condensate on the inclined surface at the bottom of the guide seat 3. The condensate flows along the inclined bottom surface of the guide seat 3 to the lowest point and drips into the upper capillary tube 301, or the condensate drips directly into the upper capillary tube 301. After the upper capillary tube 301 receives the condensate, it guides the condensate along the inclined direction of the upper capillary tube 301 to the side capillary tube 3011. The side capillary tube 3011 then guides the water downwards to the lower capillary tube 3014. The lower capillary tube 3014 guides the water into the inner side of the flow-concentrating hood 6. The condensate flows along the drainage channel 3012 inside the upper capillary tube 301, the side capillary tube 3011, and the lower capillary tube 3014. External dry air is filtered by the air inlet end seat 2 and then enters the airflow guide hole inside the drainage channel 3012 through the connecting pipe 2012. 3013, the dry air blown out from the airflow guide hole 3013 flows along the inner wall of the drain groove 3012, quickly blowing the condensate water adhering to the inner wall of the drain groove 3012 downward, accelerating the flow speed of the condensate water along the drain groove 3012, so that the condensate water is more quickly collected and discharged downward under the action of gravity. At the same time, the dry air flow accelerates the evaporation of the moisture remaining in the drain groove 3012. The evaporated water vapor is carried upward with the airflow and discharged from the gap between the guide seat 3 and the guide seat 3 outside the distribution box 1, preventing the condensate water from spreading everywhere inside the distribution box 1. When rainwater from the external environment seeps into the distribution box 1 through gaps or enters the interior of the distribution box 1 through the heat exchange baffle 401 of the maintenance baffle 4, the water flows downward along the inner wall of the distribution box 1 and the outer surface of the guide seat 3 (the guide seat 3 is located inside the distribution box 1, and its outer surface faces the interior space). After being collected by the upper capillary tube 301, the side capillary tube 3011, and the lower capillary tube 3014, the water is also guided into the inner side of the current-collecting hood 6. The current-collecting hood 6 receives the water from the upper capillary tube 301. All the water in the capillary tube 301, the side capillary tube 3011, and the bottom capillary tube 3014 is collected in a concentrated manner. The dust and rust carried by the water are deposited at the bottom of the inner side of the flow collection hood 6. The water collected in the flow collection hood 6 flows downward into the collection pipe 601 under the action of gravity. The built-in filter element 6011 filters the water entering the collection pipe 601, intercepting the fine impurities in the water upstream of the collection pipe 601. The filtered water flows downward into the connecting pipe 7 through the collection pipe 601. When water continuously flows into the drain sleeve 701 from the connecting pipe 7, the water is temporarily buffered inside the drain sleeve 701. Under normal conditions, the quick-drain magnetic ring 7013 is de-energized, and the magnetic support 7014 is in the upward position under the elastic force of the return spring 7016. The sealing piston 7015 is simultaneously in the upward position along with the magnetic support 7014, sealing the top opening of the drain sleeve 701. The water buffered inside the drain sleeve 701 cannot be discharged, and the water continues to accumulate inside the drain sleeve 701. As the water level inside the drain sleeve 701 gradually rises... The downward water pressure generated by the water on the sealing piston 7015 gradually increases. When the water pressure increases to exceed the elastic holding force of the return spring 7016, the sealing piston 7015 is pushed downward by the water and releases the seal on the top opening of the drain sleeve 701. The water buffered in the drain sleeve 701 is naturally discharged outward under the action of gravity through the drain port 7012 opened inside the drain base 7011. As the water level in the drain sleeve 701 drops, the water pressure decreases, and the return spring 7016 pushes the magnetic support 7014 and the sealing piston 7015 upward again and restores the sealing state. When there is heavy rainfall or when the drainage sleeve 701 is clogged with debris, causing poor drainage and severe water accumulation, the quick-drain magnetic ring 7013 is energized. The quick-drain magnetic ring 7013 generates a magnetic attraction force. The magnetic support 7014, under the magnetic attraction of the quick-drain magnetic ring 7013, overcomes the elastic force of the return spring 7016 and moves downwards. The sealing piston 7015 moves downwards synchronously with the magnetic support 7014, forcibly opening the top opening of the drainage sleeve 701. The water buffered inside the drainage sleeve 701 is actively discharged through the drainage port 7012 inside the drainage base 7011. After drainage is completed, the quick-drain magnetic ring 7013 is de-energized and demagnetized. The return spring 7016, under its own elastic restoring force, pushes the magnetic support 7014 upwards. The sealing piston 7015 moves upwards synchronously with the magnetic support 7014 and... The top opening of the drain sleeve 701 is resealed. The dust cover 7017 provides dust isolation protection for the return spring 7016 on the outside of the return spring 7016, preventing external dust from adhering to the surface of the return spring 7016. When the amount of waste residue deposited at the bottom of the inner side of the flow-collecting hood 6 reaches the level that needs to be cleaned, the maintenance personnel start the servo motor 5011 to drive the slag discharge auger 5012 to rotate inside the slag removal pipe 5. The open end of the slag discharge pipe 501 sucks the waste residue floating and deposited inside the flow-collecting hood 6 into the slag removal pipe 5. The rotation of the slag discharge auger 5012 drives the waste residue to be transported upward along the slag removal pipe 5. The waste residue is discharged outside the power distribution box 1 through the slag discharge pipe 501. After the slag is discharged, the servo motor 5011 is turned off. The maintenance baffle 4 is reconnected to the power distribution box 1 by the fixing bolt 4011, and the power distribution box 1 returns to a sealed state.
