Description

Technical Field

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

[0002] Intelligent low-voltage integrated distribution boxes are typically installed on the low-voltage side of distribution transformers, at the end of building power distribution systems, or at outdoor power distribution nodes. They are used to collect, distribute, protect, meter, and monitor low-voltage power, and to achieve local visualization and remote operation and maintenance through data acquisition and communication modules.

[0003] A low-voltage integrated distribution box in the related technology includes a box body and an overhanging top cover disposed on the top of the box body. Several ventilation holes are provided on the lower end face of the overhanging top cover, allowing the box body to exchange air, equalize pressure, or dissipate heat through the ventilation holes.

[0004] However, under strong wind and snow conditions, directional airflow channels can easily form at the vents. The snow powder carried by the vents may enter the interior of the cover under the action of wind pressure and then rush straight into the box, causing the humidity around the electrical components inside the box to increase or even form condensation, which in turn can damage the electrical components. Summary of the Invention

[0005] In order to improve the problem that the vents of the cantilevered top cover are prone to forming directional airflow channels under strong wind and snow conditions, which can cause snow powder to enter the box through the vents and directly rush into the box, resulting in increased humidity and even condensation, which can damage electrical components, this application provides an intelligent low-voltage integrated distribution box.

[0006] This application provides an intelligent low-voltage integrated distribution box, which adopts the following technical solution: An intelligent low-voltage integrated distribution box includes a box body with a storage cavity inside. A cover is provided on the top of the box body, extending beyond the vertical projection area of ​​the box body. A receiving cavity is provided within the cover, with a receiving hole communicating with the storage cavity on the lower inner wall of the receiving cavity. A vent hole communicating with the receiving cavity is provided on the lower end face of the overhanging portion of the cover extending beyond the box body. A mounting frame surrounding the axis of the receiving hole is provided on the lower inner wall of the receiving cavity. A buffer cavity and a mounting cavity located below the buffer cavity are provided within the mounting frame. A mounting ring groove communicating with the vent hole is provided on the lower end face of the mounting frame. Both the mounting cavity and the buffer cavity are located in the inner area enclosed by the mounting ring groove. The inner wall of the buffer cavity, away from the axis of the receiving hole, has a separation channel communicating with the mounting ring groove. A blocking mechanism is provided in the buffer cavity, and the blocking mechanism is located on the blowing path of the air outlet of the separation channel. An air inlet pipe communicating with the buffer cavity is provided on the inner wall of the mounting frame. An mounting hole communicating with the mounting cavity is provided on the lower inner wall of the buffer cavity. A sealing mechanism for sealing the mounting hole is provided in the mounting cavity. A drainage pipe communicating with the interior of the mounting cavity is provided below the mounting frame, and the end of the drainage pipe away from the mounting frame extends to the outside of the box.

[0007] By adopting the above technical solution, outside air enters the buffer chamber after passing through the vent, mounting ring groove, and separation channel. The blocking mechanism forces the airflow entering the buffer chamber to change its direction and reduces its direct impact energy, so that the snow powder and water droplets entrained in the air remain in the buffer chamber, reducing the probability of snow powder, water droplets, and other entrained particles directly entering the storage chamber and reducing the probability of damage to electrical components. When a certain amount accumulates in the buffer chamber, the sealing mechanism opens the mounting hole, allowing the snow powder and water droplets to fall into the mounting chamber under gravity and be discharged independently through the drainage pipe, thus realizing the collection and external discharge of snow powder and water droplets.

[0008] Optionally, the blocking mechanism includes a baffle connected to the inner wall of the buffer chamber, the baffle being spaced apart from the air outlet of the separation channel, and the baffle being located on the blowing path of the air outlet of the separation channel.

[0009] By adopting the above technical solution, the directional airflow ejected from the separation channel is first blocked and deflected by the baffle after entering the buffer chamber. This forces the airflow to change direction and weakens its direct impulse energy, thereby causing the entrained snow powder and water droplets to collide and coalesce at the baffle. As the weight of the snow powder and water droplets increases and they fall, they settle in the lower part of the buffer chamber, reducing the probability that the snow powder and water droplets will continue to migrate towards the air intake pipe and the receiving hole with the airflow.

[0010] Optionally, the end of the baffle facing the separation channel is provided with a perforated plate, the end of the perforated plate facing the separation channel is provided with a plurality of through holes, and the end of the perforated plate facing the baffle is provided with a plurality of fixing grooves extending to the lower end face of the perforated plate, and each through hole is connected to the fixing groove.

[0011] By adopting the above technical solution, the airflow ejected from the outlet of the separation channel is diverted and throttled through the through hole before hitting the baffle, thereby weakening the local jet velocity and reducing the direct impulse energy. This causes the entrained snow powder and water droplets to be inertially intercepted and aggregated on the surface of the perforated plate and the baffle. As the gravity of the snow powder and water droplets increases and they fall, the snow powder and water droplets settle in the lower part of the buffer chamber.

[0012] Optionally, the lower end of the baffle is bent toward the separation channel.

[0013] By adopting the above technical solution, the lower end of the baffle is bent towards the separation channel, which enhances the inertial interception effect on the snow powder and water droplets. In addition, the airflow is guided so that the airflow blows the droplets formed on the surface of the baffle, accelerating the droplets to gather in the bending area and fall downward under the action of gravity.

[0014] Optionally, the separation channel includes a reversing cavity located directly above the mounting ring groove. The lower inner wall of the reversing cavity has an air inlet communicating with the mounting ring groove and an air outlet communicating with the buffer cavity. The air outlet's blowing path points towards the baffle.

[0015] By adopting the above technical solution, the external airflow enters the deflection chamber through the air inlet, completes the deflection and reversal in the deflection chamber, and then is sprayed into the buffer chamber through the air outlet, eliminating the straight line of sight from the mounting ring groove to the buffer chamber, thereby weakening the tendency of snow powder and water droplets to rush directly into the buffer chamber.

[0016] Optionally, the sealing mechanism includes a spring disposed on the lower inner wall of the mounting cavity, and a sealing plate for sealing the mounting hole is disposed at the upper end of the spring. The spring is in a compressed state when the sealing plate closes the mounting hole.

[0017] By adopting the above technical solution, when the weight above the sealing plate increases, the sealing plate will descend and the mounting hole will open, allowing snow powder and water droplets in the buffer cavity to enter the mounting cavity through the mounting hole; when the weight on the sealing plate decreases, the sealing plate can return to its original position in time under the action of the spring and close the mounting hole.

[0018] Optionally, a guide tube is provided on the lower inner wall of the mounting cavity, and a guide rod inserted into the guide tube is provided on the lower end face of the sealing plate.

[0019] By adopting the above technical solution, the guide tube and guide rod are used to guide the lifting and lowering of the sealing plate, ensuring that the sealing plate is reliably reset and seals the installation hole.

[0020] Optionally, the mounting frame is provided with a lifting mechanism for driving the sealing plate to rise and fall. The lifting mechanism includes a rope connected to the lower end of the sealing plate and a mounting frame located at the lower end of the mounting frame. The end of the rope away from the sealing plate passes through the mounting frame and extends outside the mounting frame. The end of the rope away from the sealing plate is connected to a moving iron core. An electromagnet is provided on the mounting frame located directly below the moving iron core. An energy storage element for powering the electromagnet is provided in the accommodating cavity. A solar panel for electrically connecting to the energy storage element is provided on the top of the box cover.

[0021] By adopting the above technical solution, when the electromagnet is energized, it attracts and drives the moving iron core, causing the moving iron core to descend. The moving iron core then pulls the sealing plate through the rope, opening the mounting hole. This overcomes the problem of poor opening that may occur under extreme conditions such as ice adhesion, snow powder blockage, or negative pressure back suction when relying solely on the passive opening and closing of the spring. Furthermore, the solar panel converts the inexhaustible solar energy in nature into electrical energy for storage, achieving energy-saving and power-saving effects.

[0022] Optionally, the lower end of the sealing plate is fixedly connected to a folded tube sleeved outside the spring, and the lower end of the folded tube is fixedly connected to the lower inner wall of the mounting cavity.

[0023] By adopting the above technical solution, the spring is protected, reducing the risk of spring corrosion, icing and sticking, and jamming; if there is dirt adhering to the surface of the folded tube, the folding and unfolding action of the folded tube can loosen the dirt, so that water can remove the dirt from the surface of the folded tube when it passes through.

[0024] Optionally, the drainage pipe includes a water collection ring pipe located directly below the mounting frame, an outlet pipe for communicating with the mounting cavity is provided above the water collection ring pipe, and a serpentine heat dissipation pipe is provided below the drainage pipe, with one end of the heat dissipation pipe away from the water collection ring pipe extending out of the casing.

[0025] By adopting the above technical solution, the drain pipe can exchange heat with the air inside the box to cool the inner wall of the box. The use of serpentine heat dissipation pipe can increase the heat exchange area and flow path, improve the heat dissipation effect, and delay the rapid freezing of the drain medium inside the pipe and reduce the risk of ice blockage in low temperature environment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: Outside air enters the buffer chamber after passing through the vent, mounting ring groove, and separation channel. The blocking mechanism forces the airflow into the buffer chamber to change direction and reduces its direct impact energy, keeping the snow powder and water droplets entrained in the air within the buffer chamber. This reduces the probability of these particles directly entering the storage chamber, thus lowering the chance of damage to electrical components. When a certain amount accumulates in the buffer chamber, the sealing mechanism opens the mounting hole, allowing the snow powder and water droplets to fall into the installation chamber under gravity and be discharged independently through a drainage pipe, achieving the collection and external discharge of snow powder and water droplets. The sealing plate is pressed by a spring and works with a guide tube and guide rod to achieve stable guidance and reset, so that the sealing plate can reliably open and close the installation hole. With the help of a lifting mechanism composed of an electromagnet, a moving iron core and a rope, the installation hole can also be actively opened and closed. Attached Figure Description

The energy storage element and controller are both electrically connected to the heating strip. In cold weather and when there is ice inside the heat dissipation pipe 73, the heat dissipation pipe 73 is heated to melt and expel the ice.

[0063] The implementation principle of an intelligent low-voltage integrated distribution box in this application embodiment is as follows: Under the action of temperature and pressure difference, the outside air passes through the vent 23 on the cover 2 and flows into the mounting ring groove 31 of the mounting frame 3. The airflow then enters the buffer chamber 34 through the separation channel 35, wherein the separation channel 35 is provided with a deflection chamber 353. The airflow first enters the deflection chamber 353 through the air inlet 351 and completes the deflection and reversal in the deflection chamber 353. Then, it is sprayed into the buffer chamber 34 as a directional jet through the air outlet 352. The blowing path of the air outlet 352 points to the baffle 41, so that the jet first divides, throttles, blocks, deflects and dissipates kinetic energy with the baffle 41 and the perforated plate 42 on it, thereby weakening the direct rushing tendency and causing the entrained snow powder and water droplets to undergo inertial separation, agglomeration and weight gain during the collision and deflection process, and settle to the lower part of the buffer chamber 34 under the action of gravity. The purified air then enters the storage chamber 11 through the air inlet pipe inside the mounting frame 3, achieving the required equal pressure for air exchange in the box 1. At the same time, the water-proof and breathable membrane inside the air inlet pipe further prevents liquid water from entering.

[0064] After the sediment accumulates to a certain level in the buffer chamber 34, it falls into the lower mounting chamber 33 through the mounting hole 36 on the lower inner wall of the buffer chamber 34. The sealing mechanism 5 in the mounting chamber 33, under the action of the spring 54, forms a normal seal on the mounting hole 36, preventing moisture or liquid in the mounting chamber 33 from being drawn back into the buffer chamber 34 under the pulsation of airflow. When the weight of the sediment increases or when it needs to be cleaned, the sealing plate 53 moves down under the action of gravity or the lifting mechanism 6, opening the mounting hole 36. The settled snow powder or meltwater enters the mounting chamber 33 and is guided by the guide ramp 37 to the drain hole 38. After flowing through the water outlet pipe 71, it enters the water collection ring pipe 72 directly below the mounting frame 3 and then flows out of the box 1 through the serpentine heat dissipation pipe 73. When ice or snow powder blocks the sealing plate 53 and makes it difficult to open, the energy storage element 24 can supply power to make the electromagnet 64 attract the moving iron core 62, and the rope 61 pulls the sealing plate 53 to achieve active opening. In conjunction with the electric heating plate 391 in the mounting rod 32, the buffer chamber 34 area is heated and melted to ensure that the sediment can be discharged in time.
