Description

Technical Field

[0001] This invention relates to the field of metering box technology, and specifically to a quick-installation intelligent metering box. Background Technology

[0002] A metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, and boxes. In existing technology, to prevent electrical components from generating high temperatures during operation, multiple ventilation holes are usually opened on the side of the electricity metering box to allow air circulation between the inside and outside of the box, thereby dissipating heat and cooling the electrical components inside the box.

[0003] For example, patent document CN117578204A, entitled "An Electricity Metering Box," includes a box body with multiple heat dissipation holes. A receiving cavity communicating with the heat dissipation holes is also present on the box body. A support rod is rotatably connected within the receiving cavity, and a waterproof cloth is attached to the support rod. The waterproof cloth covers the heat dissipation holes, and the support rod can be rotated. By attaching the waterproof cloth to the support rod and allowing the support rod to rotate, the waterproof cloth effectively blocks the heat dissipation holes, preventing rainwater from entering the box body through them.

[0004] For example, patent document CN119482091A, entitled "A Multifunctional Electricity Metering Box," includes an electricity metering box. Each of the two side walls of the electricity metering box has a connecting groove, and each of the two connecting grooves has a first inner groove. Each of the two side walls of the electricity metering box has a first heat dissipation vent and a second heat dissipation vent, with two second heat dissipation vents located below the two first heat dissipation vents. A mounting bracket is installed at the bottom of the inner wall of the electricity metering box. Each of the two side walls of the mounting bracket has a third heat dissipation vent, and the two third heat dissipation vents are adapted to fit between the two sets of first and second heat dissipation vents. This positions the third heat dissipation vents on the mounting bracket between the two sets of first and second heat dissipation vents and in contact with the inner wall of the electricity metering box, thus closing the airflow channel to prevent rainwater intrusion.

[0005] However, in the process of using the above-mentioned literature, although the electricity metering box can prevent rainwater from entering by closing the side heat dissipation holes, in the case of continuous rainfall, closing the heat dissipation holes for a long time will hinder the air circulation inside and outside the box, resulting in heat accumulation, which can easily cause the internal electrical components to malfunction due to excessive operating temperature. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-installation intelligent metering box. This solution addresses the technical problem mentioned in the background art, where prolonged closure of the heat dissipation vents hinders airflow inside and outside the box, leading to heat accumulation and potentially causing internal electrical components to malfunction due to excessively high operating temperatures.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A quick-installation intelligent metering box includes a box body and a mounting plate detachably connected thereto. The bottom of the box body has ventilation holes, and a sealing assembly is provided on the box body to seal the ventilation holes. A cooling plate for mounting electrical components is fixedly installed inside the box body, and a cooling pipe is fixedly inserted through the cooling plate, with both ends of the cooling pipe extending to the outside of the box body. A water collection tank is slidably installed on the side of the box body, and a first spring is installed between the water collection tank and the box body. An automatic connection assembly is provided between the drain end of the water collection tank and the inlet end of the cooling pipe. When the water collection tank is full of water and the inflow rate is greater than the drainage rate, the water collection tank moves downward against the elastic force of the first spring and seals the ventilation holes through the sealing assembly. Simultaneously, the water collection tank is connected to the cooling pipe through the automatic connection assembly, and rainwater enters the cooling pipe and cools the electrical components through the cooling plate.

[0008] Furthermore, the sealing assembly includes a sealing plate and a sliding rod. The sealing plate is slidably mounted on the housing and has through holes for aligning with or offset from the heat dissipation holes. One end of the sliding rod is connected to the water collection tank, and the other end is fixedly connected to the sealing plate so as to drive the sealing plate to move when the water collection tank slides, thereby sealing or opening the heat dissipation holes.

[0009] Furthermore, a sliding groove is provided on the side of the box body, and a slider is slidably arranged in the sliding groove. The slider is fixedly connected to the water collection tank, and the slider is also fixedly connected to the sliding rod. The first spring is located in the sliding groove, and its two ends are fixedly connected to the slider and the sliding groove respectively.

[0010] Furthermore, the housing is provided with at least two air blowing components, which are arranged diagonally inside the housing and blow air in opposite directions to form a circulating airflow inside the housing, driving air to repeatedly flow through the cooling plate.

[0011] Furthermore, the cooling pipe is provided with two pipes, which are symmetrically arranged about the vertical center line of the cooling plate.

[0012] Furthermore, the blower assembly includes a rotating shaft, fan blades, and a water wheel. The rotating shaft is rotatably mounted on one side of the cooling plate, with its two ends extending to the outside of the cooling plate and the inside of the corresponding cooling pipe, respectively. The fan blades are fixedly connected to the end of the rotating shaft located outside the cooling plate, and the water wheel is fixedly connected to the end of the rotating shaft located inside the cooling pipe.

[0013] Furthermore, a drain pipe communicating with the interior of the water collection tank is fixedly installed at the bottom of the tank. The automatic connection component includes a pressure rod and a pressure block. The pressure block is slidably installed inside the water inlet of the cooling pipe to block or open the water inlet of the cooling pipe. A second spring is provided between the pressure block and the cooling pipe. The pressure rod is fixedly installed at the bottom of the drain pipe and abuts against the upper end of the pressure block to open the water inlet of the cooling pipe and connect the drain pipe with the cooling pipe.

[0014] Furthermore, a filter screen is fixedly installed at the top opening of the water collection tank, and the outline size of the filter screen matches the inner outline of the water collection tank.

[0015] Furthermore, a docking block is fixedly provided on one side of the housing, and a docking frame is fixedly provided on one side of the mounting plate. The docking block is movably embedded in the docking frame, and a plug-in component for detachable connection is provided between the docking frame and the docking block.

[0016] Furthermore, the plug-in assembly includes a plug rod and a third spring. A receiving groove is provided in the docking frame. The plug rod is slidably disposed in the receiving groove. An annular plate is fixedly disposed on the plug rod. The two ends of the third spring are fixedly connected to the annular plate and the receiving groove, respectively. A plug hole is provided on one side of the docking block. One end of the plug rod extends to the outside of the docking frame, and its other end is plugged into the plug hole for locking or releasing the docking block.

[0017] The beneficial effects of this invention are as follows: The housing is equipped with a sealing component, a water collection tank, an automatic connection component, a cooling plate, and cooling pipes on the cooling plate. During continuous rainfall, when the water collection tank is full and the inflow rate exceeds the outflow rate, excess rainwater continuously overflows from its top. At this time, the water collection tank, due to its increased weight, overcomes the elastic force of the first spring and moves downwards. The sealing component then seals the heat dissipation holes, preventing rainwater from flowing into the housing and causing electrical components inside to become damp and short-circuit. Simultaneously, the water collection tank is connected to the cooling pipes via the automatic connection component, allowing rainwater to enter the cooling pipes and cool the electrical components through the cooling plate. This avoids the problem of heat accumulation inside the housing due to prolonged closure of the heat dissipation holes in continuous rainfall, thereby preventing internal electrical components from malfunctioning due to excessive operating temperature and ensuring stable operation of the equipment under severe weather conditions.

[0020] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown, a quick-installation intelligent metering box includes a box body 1 and a mounting plate 2 detachably connected to it. Each of the four corners of the mounting plate 2 has through holes 19. During installation, expansion bolts can be passed through the corresponding through holes 19 to fix the mounting plate 2 to the mounting surface of the building structure. A door 3 is hinged to the front of the box body 1, and a docking block 4 is fixedly installed at the center of the rear side of the box body 1. A docking frame 5 is fixedly installed at the center of the side of the mounting plate 2 opposite to the box body 1. The docking block 4 is movably embedded in the docking frame 5. Plug-in components for detachable connection are symmetrically installed between the docking frame 5 and the docking block 4, facilitating quick assembly and disassembly of the box body 1.

[0022] like Figure 3As shown, the plug-in assembly includes a plug rod 6 and a third spring 7. A receiving groove 8 is horizontally formed inside the docking frame 5, and the plug rod 6 is slidably installed in the receiving groove 8. An annular plate 9 is fixedly fitted around the outer periphery of the plug rod 6, and the annular plate 9 slides in cooperation with the receiving groove 8. The third spring 7 is fitted around the outer periphery of the plug rod 6, and both ends of the third spring 7 are fixedly connected to the annular plate 9 and the groove wall of the receiving groove 8, respectively. A plug hole 10 adapted to the plug rod 6 is formed on one side of the docking block 4. One end of the plug rod 6 extends to the outside of the docking frame 5 and is fixedly fitted with a handle, while its other end is plugged into the plug hole 10 for locking or releasing the docking block 4. When installing housing 1, pull the plug rod 6 outward using the handle. The movement of plug rod 6 compresses the third spring 7 via the annular plate 9, causing the mating block 4 on housing 1 to fully embed into the mating frame 5, aligning the insertion hole 10 with plug rod 6. Then, release the handle; the restoring force of the third spring 7 causes plug rod 6 to insert into the corresponding insertion hole 10, thus completing the rapid installation of housing 1. This structure is simple in design, easy to operate, and significantly improves on-site installation efficiency.

[0023] A wedge-shaped surface is provided at the end of the insertion rod 6 that mates with the insertion hole 10, with the wedge-shaped surface facing the mating block 4. Thus, when the mating block 4 is inserted into the mating frame 5, the wedge-shaped surface of the mating block 4 slides against the insertion rod 6, pressing the insertion rod 6 outward and compressing the spring. When the insertion hole 10 moves to align with the insertion rod 6, the restoring force of the third spring 7 causes the insertion rod 6 to be inserted into the corresponding insertion hole 10, completing the locking and fixing. This structure eliminates the need for manually pulling the insertion rod 6, further improving the installation efficiency of the housing 1.

[0024] like Figure 1 , Figure 4 and Figure 6 As shown, several heat dissipation holes 11 are provided on both the left and right sides of the bottom of the box 1. The heat dissipation holes 11 on the left and right sides are arranged opposite each other to promote air circulation inside and outside the box 1, accelerate the dissipation of heat inside the box 1, and thus effectively reduce the working temperature inside the box 1. Water collection tanks 12 are slidably installed on both the left and right sides of the box 1. The top of the water collection tank 12 is open, and the side of the top of the water collection tank 12 closer to the box 1 is higher than the side away from the box 1, so that rainwater can flow out from the side of the water collection tank 12 away from the box 1. A first spring 13 is installed between the water collection tank 12 and the box 1. Specifically, sliding grooves 14 are symmetrically provided on both the left and right sides of the box 1. A slider 15 is slidably installed in the sliding groove 14. One side of the slider 15 is fixedly connected to the corresponding water collection tank 12. The first spring 13 is located in the sliding groove 14, and its two ends are fixedly connected to the slider 15 and the bottom wall of the sliding groove 14, respectively. A handle 16 is fixedly installed at the bottom of the water collection tank 12, which allows the operator to easily move and transfer the tank 1 by holding the handle 16.

[0025] like Figures 4-6As shown, sealing assemblies for sealing the corresponding heat dissipation holes 11 are installed on both the left and right sides of the housing 1. Each sealing assembly includes a sealing plate 17 and a sliding rod 20. A mounting groove 18 is provided at the center of several heat dissipation holes 11 along its length at the bottom of the housing 1. The sealing plate 17 is vertically slidably installed in the mounting groove 18, and has through holes 19 that correspond one-to-one with and are aligned with or staggered from the heat dissipation holes 11. There are two sliding rods 20, which slide through the interior of the side wall of the housing 1. The top end of each sliding rod 20 is fixedly connected to a corresponding slider 15, and the other end is fixedly connected to the sealing plate 17. This allows the sealing plate 17 to move when the water collection tank 12 slides, thus sealing or opening the heat dissipation holes 11. When the sealing plate 17 slides to the open position, the through holes 19 are aligned with the heat dissipation holes 11, ensuring the heat dissipation holes 11 remain unobstructed. When the sealing plate 17 slides to the closed position, the plate surface of the baffle blocks the heat dissipation hole 11 to prevent rainwater from entering the interior of the box 1.

[0026] During continuous rainfall, when the water collection tank 12 is full and the inflow rate exceeds the outflow rate, excess rainwater continuously overflows from its top. At this time, the water collection tank 12, due to its increased weight, overcomes the elastic force of the first spring 13 and moves downwards. Simultaneously, the sliding rod 20 drives the sealing plate 17 to move downwards, causing the through hole 19 on the sealing plate 17 to misalign with the heat dissipation hole 11, thereby sealing the heat dissipation hole 11. This structure prevents rainwater from flowing into the housing 1, preventing the electrical components 21 inside the housing 1 from short-circuiting due to moisture, ensuring normal operation of the equipment under severe weather conditions, and reducing the risk of failure.

[0027] In another embodiment, the heat dissipation holes 11 are arranged at an angle. When the rainfall intensity is weak, i.e., the drainage rate of the water collection tank 12 is greater than the inflow rate, the angled structure of the heat dissipation holes 11 can reduce the possibility of rainwater entering the housing 1. At the same time, the water collection tank 12 is located directly above the heat dissipation holes 11, which can protect the heat dissipation holes 11 from rain. Thus, rainwater intrusion is reduced under weak rainfall conditions, further ensuring the safety of the electrical components 21 inside the housing.

[0028] like Figure 7 and Figure 9As shown, a cooling plate 22 for housing electrical components 21 is fixedly installed near the rear of the enclosure 1. The electrical components 21 include an electricity meter, a metering transformer, a circuit breaker, and a fuse. The cooling plate 22 is made of aluminum or copper, possessing excellent thermal conductivity, allowing for timely heat exchange with the electrical components 21 and significantly improving heat dissipation efficiency. Two cooling pipes 23 are fixedly installed inside the cooling plate 22, symmetrically arranged about the vertical center line of the cooling plate 22. The cooling pipes 23 are in a continuous "S" shape to increase the cooling area and improve heat exchange efficiency. The inlet and outlet ends of the cooling pipes 23 extend to the top and bottom of the enclosure 1, respectively. An automatic connection assembly is installed between the drain end of the water collection tank 12 and the inlet end of the cooling pipes 23. The water collection tank 12 is connected to the cooling pipes 23 via the automatic connection assembly, allowing rainwater to enter the cooling pipes 23 and cool the electrical components 21 through the cooling plate 22. This avoids the problem of heat buildup inside the enclosure 1 due to prolonged closure of the heat dissipation vents 11 in continuous rainfall, thereby preventing internal electrical components 21 from malfunctioning due to excessive operating temperature and ensuring stable operation of the equipment in severe weather.

[0029] like Figure 8 As shown, a drain pipe 24 communicating with the bottom of the water collection tank 12 is fixedly installed. The automatic connection component includes a pressure rod 25 and a pressure block 26. A first connecting frame is fixedly installed inside the water inlet end of the cooling pipe 23. A connecting rod 27 is fixedly installed at the center of the bottom surface of the pressure block 26. The connecting rod 27 is vertically slidably installed at the center of the first connecting frame. A second spring 28 is sleeved on the outer periphery of the connecting rod 27. The two ends of the second spring 28 are fixedly connected to the pressure block 26 and the first connecting frame, respectively, to provide an upward restoring force to the pressure block 26. A sealing ring 29 is fixedly installed inside the water inlet end of the cooling pipe 23. The pressure block 26 has a frustum-shaped structure. The bottom of the pressure block 26 is in a sealing sliding fit with the inner side of the sealing ring 29 to seal or open the water inlet end of the cooling pipe 23. A second connecting bracket is fixedly installed inside the drain pipe 24. A pressure rod 25 is fixedly installed at the center of the second connecting bracket and extends downward. The pressure rod 25 abuts against the upper end of the pressure block 26 to open the water inlet of the cooling pipe 23, so that the drain pipe 24 is connected to the cooling pipe 23.

[0030] As the water collection tank 12 moves downward, it simultaneously drives the drain pipe 24 downward. The drain pipe 24 then drives the pressure rod 25 downward. The bottom end of the pressure rod 25 abuts against the top of the pressure block 26, pushing the pressure block 26 downward and compressing the second spring 28. When the bottom of the drain pipe 24 enters the sealing ring 29 and fits against the inner side of the sealing ring 29, the drain pipe 24 stops moving downward. At this time, rainwater can flow into the cooling pipe 23 along the conical surface of the pressure block 26, and after heat exchange with the cooling plate 22 through the cooling pipe 23, it is discharged from the outlet end at the bottom of the cooling pipe 23 to the outside of the box 1. After the cooling plate 22 cools down, it also cools the hot air inside the box 1 and the electrical components 21 that are in direct contact with it. At the same time, after the air temperature inside the box 1 decreases, it further cools the electrical components 21 inside the box 1, thereby preventing the electrical components 21 from malfunctioning due to the continuous high temperature inside the box 1 caused by the closure of the heat dissipation hole 11.

[0031] like Figure 9 As shown, four sets of air-blowing components are installed inside the housing 1. These four sets of air-blowing components are arranged diagonally inside the housing 1, with opposite airflow directions, to create a circulating airflow inside the housing 1. The circulating airflow can directly cool the electrical components 21, improving the cooling effect. At the same time, it drives the air to repeatedly flow through the cooling plate 22, accelerating the heat exchange efficiency between the air and the cooling plate 22, further enhancing the cooling effect on the electrical components 21.

[0032] like Figures 9-11 As shown, the blower assembly includes a rotating shaft 30, fan blades 31, and a water wheel 32. The rotating shaft 30 is rotatably mounted on one side of the cooling plate 22, with its two ends extending to the outside of the cooling plate 22 and the inside of the corresponding cooling pipe 23, respectively. The fan blades 31 are fixedly connected to the end of the rotating shaft 30 located outside the cooling plate 22, and the water wheel 32 is fixedly connected to the end of the rotating shaft 30 located inside the cooling pipe 23. Specifically, the water wheel 32 includes three blades arranged in a circular array along the outer circumference of the rotating shaft 30. The blades have a spoon-shaped structure, and the spoon-shaped curved surfaces at the tips of each blade face the same direction.

[0033] When rainwater flows within the cooling pipe 23, the water flow impacts the blades of the water wheel 32, driving the water wheel 32 to rotate. The water wheel 32 drives the fan blades 31 to rotate synchronously via the rotating shaft 30. The rotation of the fan blades 31 generates airflow, creating air cooling within the housing 1. The airflow directly blows onto the electrical components 21, achieving air cooling; simultaneously, it flows through the cooling plate 22, accelerating the heat exchange efficiency between the air inside the housing 1 and the cooling plate 22, further improving the heat dissipation effect on the electrical components 21. This meets the equipment's operating requirements under high load or high temperature environments, reduces maintenance costs, effectively protects the electrical components 21, and ensures the stable and reliable operation of the entire system.

[0034] A filter screen 33 is fixedly installed at the top opening of the water collection tank 12. The outline of the filter screen 33 matches the inner outline of the water collection tank 12. This filters impurities in the rainwater and prevents the drain pipe 24 and cooling pipe 23 from becoming clogged.

[0035] Working principle: During installation, the mounting plate 2 is fixedly connected to the mounting surface of the building structure by passing expansion bolts through the corresponding through holes 19. Then, the housing 1 is installed by pulling the plug rod 6 outward with the handle. The movement of the plug rod 6 compresses the third spring 7 through the annular plate 9. Then, the mating block 4 on the housing 1 is fully embedded into the mating frame 5, and the plug hole 10 is aligned with the plug rod 6. Then, the handle is released, and under the action of the restoring force of the third spring 7, the plug rod 6 is inserted into the corresponding plug hole 10, thereby completing the quick installation of the housing 1.

[0036] During continuous rainfall, when the water collection tank 12 is full of rainwater and the inflow rate is greater than the drainage rate of the bottom drain pipe 24, excess rainwater overflows from the top of the water collection tank 12. At this time, the water collection tank 12 moves downwards due to its increased weight, overcoming the elastic force of the first spring 13. It also moves downwards synchronously through the sliding rod 20, causing the through hole 19 on the sealing plate 17 to be misaligned with the heat dissipation hole 11, thereby sealing the heat dissipation hole 11 and preventing rainwater from entering the tank 1 and causing the electrical components 21 to become damp and short-circuit.

[0037] As the water collection tank 12 moves downward, it simultaneously drives the drain pipe 24 downward. The drain pipe 24 then drives the pressure rod 25 downward. The bottom end of the pressure rod 25 abuts against the top of the pressure block 26, pushing the pressure block 26 downward and compressing the second spring 28. When the bottom of the drain pipe 24 enters the sealing ring 29 and fits against the inner side of the sealing ring 29, the drain pipe 24 stops moving downward. At this time, rainwater can flow into the cooling pipe 23 along the conical surface of the pressure block 26, and after heat exchange with the cooling plate 22 through the cooling pipe 23, it is discharged from the outlet end at the bottom of the cooling pipe 23 to the outside of the box 1. After the cooling plate 22 cools down, it also cools the hot air inside the box 1 and the electrical components 21 that are in direct contact with it. At the same time, after the air temperature inside the box 1 decreases, it further cools the electrical components 21 inside the box 1, thereby preventing the electrical components 21 from malfunctioning due to the continuous high temperature inside the box 1 caused by the closure of the heat dissipation hole 11.

[0038] When rainwater flows within the cooling pipe 23, the water flow impacts the blades of the water wheel 32, driving the water wheel 32 to rotate. The water wheel 32 drives the fan blades 31 to rotate synchronously via the rotating shaft 30. The rotation of the fan blades 31 generates airflow, creating air cooling within the housing 1. The airflow directly blows onto the electrical components 21, achieving air cooling; simultaneously, it flows through the cooling plate 22, accelerating the heat exchange efficiency between the air inside the housing 1 and the cooling plate 22, further improving the heat dissipation effect on the electrical components 21. This meets the equipment's operating requirements under high load or high temperature environments, reduces maintenance costs, effectively protects the electrical components 21, and ensures the stable and reliable operation of the entire system.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
