Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and in particular to an intelligent integrated distribution box. Background Technology

[0002] Intelligent integrated distribution boxes are core equipment of power systems, featuring intelligent monitoring, remote control, high efficiency and energy saving, and safety and reliability.

[0003] The intelligent integrated distribution box includes a box body, which contains an incoming line unit, a metering and sensing unit, a control unit, etc.

[0004] Existing intelligent integrated distribution boxes are usually installed on the exterior walls of buildings, with the back of the box often close to or only forming a narrow gap with the wall. Under the influence of rain, humid air, or water seepage from the exterior walls, moisture and soluble salts in the wall easily migrate to the back of the box under the drive of capillary action and wet-dry cycles, accumulating and crystallizing at the contact boundary. This causes a swelling effect on the interface of the box's outer coating, resulting in defects such as blistering and bulging on the back of the box. These defects further disrupt the continuity of the protective layer on the outer surface and form interface cavities that are prone to water retention and salt accumulation, accelerating the corrosion and deterioration process. Consequently, the weather resistance and corrosion resistance of the box's outer shell are reduced, shortening the service life of the box. Summary of the Invention

[0005] In order to improve the problem that the back of the intelligent integrated distribution box is prone to blistering and bulging due to the migration and accumulation of moisture and soluble salts on the wall when it is installed on the exterior wall of a building, which leads to a shortened service life, this application provides an intelligent integrated distribution box.

[0006] This application provides an intelligent integrated distribution box, which adopts the following technical solution: An intelligent integrated distribution box includes a box body mounted on a wall. The box body includes a mounting surface near the wall, and a mounting frame surrounding the mounting surface. The side of the mounting frame facing away from the box body forms abutment edge for abutting against the wall. The abutment edge abuts against the wall to form a mounting cavity between the mounting surface and the wall. The lower part of the mounting frame has an air inlet channel communicating with the outside and the mounting cavity. The upper end of the mounting frame has an air outlet channel communicating with the outside and the mounting cavity. The air outlet channel is higher than the air inlet channel. Outside air can enter the mounting cavity through the air inlet channel and exit through the air outlet channel to form natural convection. A water-blocking mechanism is provided at the air outlet channel to prevent rainwater from directly entering the mounting cavity.

[0007] By adopting the above technical solution, after the mounting frame, mounting surface, and wall form a mounting cavity, outside air enters the mounting cavity through the air inlet channel and then exits through the air outlet channel, forming natural convection. This continuously removes moisture from the wall side and reduces the possibility of moisture forming a continuous wet film on the back of the enclosure. A water-blocking mechanism is installed at the air outlet channel, which can prevent rainwater from directly entering the mounting cavity along the channel while ensuring air exchange. This avoids external moisture entering the mounting cavity, which would lead to continuous wet film formation and increased salt migration and crystallization. This suppresses the risk of blistering and bulging on the back of the enclosure, thus maintaining the continuity and weather resistance of the enclosure's protective layer, delaying enclosure deterioration, and extending the service life of the enclosure.

[0008] Optionally, the mounting frame is provided with a plurality of vertical plates spaced apart along the length of the box. The upper end of the vertical plate is connected to the upper inner wall of the mounting cavity, the side of the vertical plate is fixedly connected to the mounting surface, and a ventilation gap is left between the lower end of the vertical plate and the lower inner wall of the mounting cavity. The vertical plate divides the mounting cavity into a plurality of vertical channels.

[0009] By adopting the above technical solution, the vertical plate divides the installation cavity into multiple vertical channels, creating multiple parallel vertical airflow paths between the box and the wall. On the one hand, it can reduce the probability of local stagnation of airflow in a single large cavity, improve the uniformity of natural convection and effective ventilation, and make it easier for moisture in the installation cavity to be carried away, weakening the conditions for the formation of a continuous wet film on the back of the box. On the other hand, the vertical plate plays a supporting role for the installation frame, improving the strength of the installation frame.

[0010] Optionally, a horizontal plate is provided on the end face of the vertical plate along the length of the box body, which is connected to the horizontal inner wall of the mounting cavity or an adjacent vertical plate.

[0011] By adopting the above technical solution, the horizontal plate forms a horizontal support and connecting component in the mounting frame, which further enhances the overall strength of the mounting frame and makes it less prone to deformation under external force. This avoids the natural convection channel being blocked or the ventilation efficiency being reduced due to cavity deformation, reduces the risk of continuous wet film forming on the back of the box and the resulting defects such as blistering and bulging, delays shell deterioration and extends the service life of the box.

[0012] Optionally, the vertical plate includes a first side and a second side opposite to each other along the length of the mounting frame. A first vent hole and a second vent hole are formed through the first side and the second side. The first vent hole and the second vent hole are spaced apart in the vertical direction. The first vent hole and the second vent hole are both inclined and in opposite directions. The opening of the first vent hole on the first side is higher than the opening of the second vent hole on the second side, and the opening of the second vent hole on the first side is lower than the opening of the second vent hole on the second side. The first vent hole and the second vent hole are staggered in the vertical direction, so that the openings of the first vent hole and the second vent hole on the first side are not on the same straight line, and the openings of the first vent hole and the second vent hole on the second side are not on the same straight line.

[0013] By adopting the above technical solution, the first and second vent holes provide a channel for air to flow through the plate for ventilation within the installation cavity.

[0014] Optionally, the lower inner wall of the mounting frame has a receiving groove, and the side of the mounting frame has a receiving hole that communicates with the receiving groove. A collection box is provided in the receiving groove, and the collection box can be pulled out along the length of the mounting frame, pass through the receiving hole, and be pulled out of the mounting frame.

[0015] By adopting the above technical solution, the condensate, entrained salt spray droplets, salt crystal particles, and dust deposits generated during natural convection dehumidification can preferentially collect at the bottom of the mounting frame and fall into the collection box under the action of gravity. This avoids the random retention of the above liquids and solids on the inner wall of the mounting cavity and the back of the box, repeated moisture absorption, and the formation of a continuous wet film or crystal accumulation that reduces the ventilation cross-section. The collection box adopts a pull-out structure, which can achieve regular cleaning and resetting without disassembling the box or damaging the installation state of the mounting frame and the wall. It can restore the dehumidification and ventilation capacity of the mounting cavity without introducing additional water supply, maintain the stability of natural convection, and thus more effectively weaken the conditions for salt capillary migration and enrichment crystallization, reduce the risk of defects such as blistering and bulging on the back of the box, and extend the service life of the box.

[0016] Optionally, the collection box is equipped with a heating mechanism, and a collection groove is formed at the upper end of the collection box. The heating mechanism includes a heating strip disposed in the collection groove, and each of the two electrodes of the heating strip is connected to a first wire. Two first mounting grooves are formed on the side of the collection box facing the housing, and a conductive element is disposed in each of the two first mounting grooves. Each of the two conductive elements is electrically connected to a first wire. A spring is also provided on the side of the conductive element facing the bottom wall of the first mounting groove. The spring is used to apply a force to the conductive element to extend it outward from the first mounting groove. An energy storage element for powering the heating strip is disposed inside the housing, and a solar panel electrically connected to the energy storage element is disposed on the top of the housing. A receiving groove is formed near the inner wall of the housing. Two second mounting slots are provided, each containing a stationary contact piece. The positive and negative terminals of the energy storage element are connected to second wires. The side of each second wire furthest from the energy storage element is electrically connected to a stationary contact piece. A controller is also provided inside the housing. At least one of the second wires connects in series with a controlled switch device between the energy storage element and the corresponding stationary contact piece. The control terminal of the controlled switch device is electrically connected to the controller. A detection branch branches off at the end of the second wire closest to the energy storage element and is electrically connected to the controller. When the collection box is in the retracted state, each of the two conductive elements elastically abuts against a stationary contact piece to form a power supply circuit to the heating strip. The controller controls the controlled switch device to turn on or off based on the electrical parameters collected by the detection branch, thereby achieving controlled power supply to the heating strip and detection of the power supply status.

[0017] By adopting the above technical solution, after the collection box is pushed into the receiving groove, the conductive component can abut against the stationary contact piece, thereby establishing a power supply circuit to the heating strip without the need for additional wiring or disassembly of the housing; conversely, when the collection box is pulled out, the power supply circuit is automatically cut off, reducing the risk of live exposure and accidental contact; when the heating strip is working, in addition to heating and evaporating the condensate, salt spray droplets, and damp deposits in the collection box and reducing the moisture content of the deposits, it can also heat the air in the installation cavity, increasing the air temperature in the installation cavity and enhancing the thermal buoyancy effect, making... The air inside the cavity is more likely to form an upward flow, thereby increasing the driving force and ventilation of natural convection, accelerating the discharge of humid air and shortening the existence time of the wet film inside the installation cavity. This makes the environment inside the installation cavity drier, further reducing the conditions for capillary migration and accumulation of moisture and soluble salts on the wall at the contact interface, reducing the probability of blistering and bulging on the back of the enclosure, and improving the durability and service life of the enclosure shell. The solar panels convert solar energy into electrical energy and power the energy storage elements without relying on the mains power, thus saving electricity and energy.

[0018] Optionally, the conductive component includes a conductive plate slidably disposed in the first mounting groove and an arc-shaped block disposed at one end of the conductive plate away from the bottom wall of the first mounting groove. The first mounting groove has elongated guide grooves on both inner walls along the length of the collection box. The conductive plate is provided with a guide block slidably disposed in the guide groove. One end of the spring abuts against the conductive plate, and the other end of the spring abuts against the bottom wall of the first mounting groove. When the arc-shaped block abuts against the stationary contact piece, the conductive plate is located outside the second mounting groove.

[0019] By adopting the above technical solution, the guide block is slidably set in the guide groove to limit and guide the movement of the conductive plate, so that the conductive plate maintains stable linear sliding during the expansion and contraction of the force, avoiding poor contact due to skew or jamming; the use of arc-shaped blocks reduces the wiping with the inner wall of the receiving groove, reducing the wear of the conductive parts; when the collection box is in the storage state, pulling the collection box will cause the arc-shaped block to contact the edge of the second mounting groove and facilitate the second mounting groove to disengage, avoiding the collection box from jamming due to the conductive parts.

[0020] Optionally, the mounting frame is provided with a closing mechanism for closing the second mounting slot. The receiving slot has a sliding groove on the inner wall near the box body. The sliding groove is located on the side of the second mounting slot away from the receiving hole and communicates with the second mounting slot. The closing mechanism includes a closing plate slidably disposed in the sliding groove. The closing plate moves in the sliding groove and has a closed state and an open state. A second storage slot is provided on the side of the closing plate away from the box body. A magnet is disposed in the second storage slot. A first storage slot is provided on the end face of the collection box facing the second mounting slot. An iron sheet for magnetic attraction with the magnet is disposed in the first storage slot. When the closing plate is in the closed state, the closing plate closes the opening of the second mounting slot. When the closing plate is in the open state, the closing plate does not close the opening of the second mounting slot.

[0021] By adopting the above technical solution, when the collection box is pulled out of the receiving hole, the iron sheet drives the magnet and the sealing plate to move, causing the sealing plate to close the second mounting slot until the sealing plate abuts against the inner wall of the second mounting slot away from the slide groove. As the collection box continues to be pulled out, the iron sheet separates from the magnet. Conversely, during the process of inserting the collection box from the receiving hole, the iron sheet and the magnet are aligned and magnetically attracted to each other. As the collection box continues to be inserted, the iron sheet drives the magnet and the sealing plate to move, opening the second mounting slot. When the sealing plate is in the closed state, it blocks the opening of the second mounting slot, which can physically isolate the stationary contact piece in the second mounting slot, preventing the stationary contact piece from being exposed after the collection box is pulled out, thus avoiding accidental contact, foreign object entry, or electrical connection failure caused by moisture or dust accumulation. When the sealing plate is in the closed state, it abuts against the inner wall of the second mounting slot away from the slide groove to form a limit, ensuring reliable sealing.

[0022] Optionally, the collection box is provided with a locking mechanism for restricting the movement of the collection box along the direction of its pull-out; the collection box has an operating cavity, and the locking mechanism includes a locking gear rotatably connected to the operating cavity, a locking rack slidably disposed on the side of the operating cavity near the collection groove, and an operating component for driving the locking rack to rise and fall. The locking gear and the locking rack mesh with each other, and the lower inner wall of the operating cavity has an operating hole for inserting the locking rack, and the lower inner wall of the receiving hole has a locking groove for inserting the locking rack.

[0023] By adopting the above technical solution, when the collection box is in the storage state, the locking rack can extend through the operating hole on the lower inner wall of the operating cavity and insert into the locking groove on the lower inner wall of the receiving hole to form a mechanical limit on the collection box; by driving the locking rack to rise and exit the locking groove through the operating component, controllable unlocking can be achieved, so that the collection box can be conveniently pulled out while ensuring safety and reliability, thereby improving the cleaning of the collection box.

[0024] Optionally, the upper end of the mounting frame has a groove, and the water-blocking mechanism includes a waterproof pipe disposed on the bottom wall of the groove. The lower end of the waterproof pipe is connected to the air outlet channel. The upper end surface of the waterproof pipe is higher than the upper end surface of the mounting frame. A hemispherical waterproof cover is disposed at the upper end of the waterproof pipe. A support rod is disposed on the inner wall of the waterproof cover. The lower end surface of the waterproof cover is lower than the upper end surface of the waterproof pipe. An annular gap for air venting is formed between the waterproof cover and the waterproof pipe. The lower end of the support rod is fixedly connected to the bottom wall of the groove.

[0025] By adopting the above technical solution, a waterproof pipe is installed above the upper surface of the mounting frame, reducing the chance of water in the groove flowing back into the mounting cavity; the annular gap formed between the waterproof cover and the waterproof pipe provides a circumferentially uniform exhaust channel for the gas, ensuring the exhaust capacity of the exhaust channel and the continuity of natural convection, and significantly reducing the risk of direct water ingress when the exhaust end is impacted by wind and rain.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the mounting frame, mounting surface, and wall form a mounting cavity, outside air enters the mounting cavity through the air inlet channel and exits through the air outlet channel, forming natural convection. This continuously removes moisture from the wall side and reduces the possibility of moisture forming a continuous wet film on the back of the enclosure. A water-blocking mechanism is installed at the air outlet channel to prevent rainwater from directly entering the mounting cavity while ensuring air exchange. This avoids external moisture entering the mounting cavity, which can lead to a continuous wet film and increased salt migration and crystallization. This suppresses the risk of blistering and bulging on the back of the enclosure, thus maintaining the continuity and weather resistance of the enclosure's protective layer, delaying enclosure deterioration, and extending the service life of the enclosure. 2. By setting a receiving groove and a removable collection box at the bottom of the mounting frame, condensate, salt spray droplets, crystal particles and dust are collected in a centralized manner. A heating strip powered by an energy storage element is set in the collection box to heat and dry the deposits and the air in the mounting cavity, and enhance thermal buoyancy to further improve the convection driving force. At the same time, in conjunction with the guide limit and elastic pre-tightening structure of the conductive parts, the sealing mechanism of the second mounting groove and the locking mechanism of the collection box, the collection box is automatically and reliably powered when stored and automatically de-energized when pulled out, and the static contact plate is shielded to prevent accidental extraction. This maintains the long-term stability and effectiveness of the ventilation and dehumidification and deposit management structure, further reduces the risk of blistering, bulging and corrosion deterioration and extends the service life of the box.

[0055] Reference Figure 4 and Figure 7The collection box 5 is equipped with a heating mechanism 7, which is used to heat the air in the collection tank 51. The heating mechanism 7 includes a heating strip 71, a conductive element 72, a spring 73, a first wire 74, a stationary contact piece 75, and a second wire 76.

[0056] Reference Figure 7 The collection box 5 has two first mounting slots 56 on its end face facing the box body 1. The two first mounting slots 56 are spaced apart along the length of the collection box 5, and there is a height difference between the two first mounting slots 56.

[0057] Reference Figure 4 and Figure 7 The bottom wall of the first mounting groove 56 is provided with mounting holes 561, which communicate with the collection groove 51. A heating strip 71 is disposed within the collection groove 51. Each end of the heating strip 71 passes through a mounting hole 561 along its length and is inserted into the first mounting groove 56. A first wire 74 is disposed within the first mounting groove 56 and is electrically connected to the two electrodes of the heating strip 71.

[0058] Reference Figure 7 Each first mounting slot 56 contains a conductive element 72 and a spring 73. The conductive element 72 is made of a conductive material, such as copper. The conductive element 72 includes a conductive plate 721 and an arc-shaped block 722. The conductive plate 721 is disposed in the first mounting slot 56, and guide blocks 723 are fixedly connected to both ends of the conductive plate 721 along the two end faces of the collection box 5. Guide grooves 562 are formed on both inner walls of the first mounting slot 56 along the length of the collection box 5, and the guide grooves 562 are horizontal elongated grooves. The guide blocks 723 are slidably disposed in the guide grooves 562. When the guide blocks 723 abut against the inner wall of the guide grooves 562 away from the bottom wall of the first mounting slot 56, the end face of the conductive plate 721 away from the bottom wall of the first mounting slot 56 is coplanar with the side face of the collection box 5.

[0059] Reference Figure 7 Two arc-shaped blocks 722 are provided, and both arc-shaped blocks 722 are fixedly connected to the conductive plate 721 away from the bottom wall of the first mounting groove 56. The two arc-shaped blocks 722 are distributed at intervals along the length of the collection box 5. In other embodiments, the arc-shaped blocks 722 may be one, three, or other quantities.

[0060] Reference Figure 7 The spring 73 is in a compressed state, with one end of the spring 73 abutting against the bottom wall of the first mounting groove 56 and the other end of the spring 73 abutting against the conductive plate 721.

[0061] Reference Figure 7 The first wire 74 is disposed in the first mounting groove 56. One end of the first wire 74 is electrically connected to the conductive plate 721, and the other end of the first wire 74 is electrically connected to the heating strip 71.

[0062] Reference Figure 7 The receiving slot 36 has two second mounting slots 38 near the inner wall of the box 1. When the collection box 5 is in the storage state, each of the two first mounting slots 56 is aligned with one of the second mounting slots 38.

[0063] Reference Figure 2 and Figure 7 Each second mounting slot 38 is provided with a stationary contact 75. The side of the stationary contact 75 facing the housing 1 is electrically connected to the second wire 76, and the side of the second wire 76 away from the stationary contact 75 is electrically connected to the positive or negative terminal of the energy storage element 162. A controlled switching device is connected in series between the energy storage element 162 and the stationary contact 75. The controlled switching device is a MOSFET or a relay.

[0064] Reference Figure 2 and Figure 7 In addition to controlling the opening and closing of the main circuit breaker and branch circuit breakers 132, the controller is also electrically connected to the power supply control circuit of the heating mechanism 7. Specifically, the controller's control output terminal is electrically connected to the control terminal of the controlled switching device, and the controller's detection input terminal is electrically connected to the detection branch led out from the second wire 76. The controller is used to determine the power supply status of the heating strip 71, the contact status between the conductive element 72 and the stationary contact piece 75, and whether the collection box 5 is in the storage state based on the voltage and / or current parameters collected by the detection branch, and accordingly control the controlled switching device to turn on or off.

[0065] Specifically, the detection branch includes a sampling resistor and two sampling lines. Each of the two electrodes of the sampling battery is electrically connected to a sampling line, and the ends of both sampling lines furthest from the sampling resistor are electrically connected to the sampling terminal of the controller 14. This allows the controller 14 to acquire the voltage across the sampling resistor and calculate the operating current of the heating strip 71 based on the resistance value. The controller 14 presets a contact threshold and an overcurrent threshold. When the detected operating current is lower than the contact threshold, it determines that the contact between the conductive element 72 and the stationary contact piece 75 is abnormal or that the circuit of the heating strip 71 has not been reliably established. When the detected operating current is higher than the overcurrent threshold, it determines that the heating strip 71 has an abnormal load or a short-circuit risk. In either of these cases, the controller 14 controls the controlled switching device to switch from the on state to the off state, thereby cutting off the power supply to the heating strip 71 to reduce the risk of arcing, overcurrent heating, and energization caused by momentary contact interruption and to improve the reliability of system operation.

[0066] Reference Figure 2 and Figure 7When the collection box 5 is in the stored state and the controller controls the controlled switching device to conduct, each of the two conductive parts 72 elastically abuts against a stationary contact piece 75 to form a power supply circuit to the heating strip 71. When the collection box 5 is pulled out or an abnormal contact is detected, the controller controls the controlled switching device to turn off to cut off the power supply to the heating strip 71.

[0067] Reference Figure 7 The mounting frame 3 is provided with a closing mechanism 8, which is used to close the second mounting slot 38 when the collection box 5 is pulled out. The closing mechanism 8 includes a closing plate 81, a magnet 82, and an iron sheet 83.

[0068] Reference Figure 7 A sliding groove 39 is provided on the inner wall of the receiving groove 36 near the housing 1. The sliding groove 39 is located on the side of the second mounting groove 38 away from the receiving hole 37. The side of the sliding groove 39 facing the receiving hole 37 communicates with the second mounting groove 38. The closing plate 81 can move within the sliding groove 39. When the closing plate 81 abuts against the inner wall of the second mounting groove 38 near the receiving hole 37, the closing plate 81 closes the second mounting groove 38, and the closing plate 81 is in a closed state. When the closing plate 81 retracts relative to the second mounting groove 38 to expose the opening of the second mounting groove 38, the closing plate 81 is in an open state.

[0069] Reference Figure 7 The end face of the closed plate 81 facing the receiving groove 36 is provided with a second storage groove 811. The magnet 82 is disposed in the second storage groove 811 and is fixedly connected to the inner wall of the second storage groove 811.

[0070] Reference Figure 7 The collection box 5 has a first storage slot 57 on its end face facing the second mounting slot 38. An iron sheet 83 is disposed in the first storage slot 57 and is fixedly connected to the inner wall of the first storage slot 57. The iron sheet 83 can magnetically engage with the magnet 82.

[0071] Reference Figure 7 During the process of the collection box 5 being pulled out of the receiving hole 37, the iron plate 83 and the magnet 82 magnetically engage, causing the sealing plate 81 to slide along the slide groove 39, so that the sealing plate 81 moves to the closed state and abuts against the inner wall of the second mounting groove 38 near the receiving hole 37. After the sealing plate 81 abuts in place, as the collection box 5 continues to be pulled out, the iron plate 83 and the magnet 82 separate. Conversely, during the process of the collection box 5 being inserted into the receiving hole 37, the iron plate 83 and the magnet 82 align and magnetically engage, and as the collection box 5 continues to be inserted, the iron plate 83 drives the magnet 82 and the sealing plate 81 to slide along the slide groove 39 to the open state.

[0072] The implementation principle of an intelligent integrated distribution box in this application embodiment is as follows: When there is a temperature difference in the external environment or the heating mechanism 7 works to raise the air temperature in the mounting cavity 31, the air density in the mounting cavity 31 decreases and flows upward along the vertical channel under the action of buoyancy, and is discharged to the outside through the air outlet channel 352; at the same time, the negative pressure formed by the air discharge in the upper part of the mounting cavity 31 causes the outside air to enter the mounting cavity 31 from the air inlet channel 32 at the lower part of the mounting frame 3, and replenishes the lower part of each vertical channel, thereby establishing a continuous airflow path from bottom to top between the air inlet channel 32 and the air outlet channel 352, forming a natural convection loop, continuously carrying out the humid air in the mounting cavity 31 and realizing ventilation and dehumidification.
