Abstract
Description
Technical Field
[0001] This utility model relates to a meter box, and more particularly to a meter box with good stability. Background Technology
[0002] A meter box is a specialized enclosure used to house and protect electrical energy metering devices. It is primarily used in power supply systems in residential, commercial, and industrial settings to measure and record the electrical energy consumed.
[0003] Ordinary electricity meter boxes have a simple design, typically using basic structures and materials to provide basic protection. However, this simple design has some potential problems. For example, meter boxes generally ventilate through ventilation holes, but due to the limited number of holes, poor ventilation can lead to a humid environment inside the box, affecting the performance and lifespan of the meter. Furthermore, the meter generates heat during operation, and the meter box typically cools down naturally, potentially resulting in high internal temperatures that accelerate meter aging. Additionally, over time, dust inevitably accumulates on the meter's reading mechanism, affecting the accuracy of the readings and requiring frequent manual cleaning, increasing maintenance costs and workload.
[0004] Therefore, a meter box with good stability is particularly needed to solve the above problems. Utility Model Content

Each door 101 is bolted to every two vertically aligned hinges 4, and the two doors 101 contact each other to close the housing 1. The handle 2 is welded to the front of the door 101 to facilitate turning the door 101. The base 5 is welded to the bottom of the housing 1. Multiple mounting plates 11 are arranged vertically at a certain interval and welded to the front of the housing 1. The enclosure also includes a ventilation assembly, a cleaning assembly, and a cooling assembly. The ventilation assembly is located on the housing 1, while the cleaning assembly and cooling assembly are located inside the housing 1.
[0022] See Figures 1-2 As shown, the ventilation assembly includes ventilation windows 3 and fans 6. Two ventilation windows 3 are distributed vertically and are connected to the front of the box door 101 by welding. Each ventilation window 3 consists of three ventilation openings, which are elongated and curved at both ends to better guide airflow and make the air flow smoother. Multiple fans 6 are arranged along a rectangular direction and are connected to the rear of the box 1 by bolts. The number of fans 6 is the same as the number of ventilation windows 3, corresponding one to one. A protective net is provided on the rear side of the fans 6 to prevent foreign objects from being drawn into the fans 6.
[0023] See Figures 2-5 As shown, the cleaning assembly includes screws 7, a motor 9, a fixing frame 10, a lifting block 12, a pulley assembly 13, a limit frame 14, a first spring 1401, a brush 15, and a movable frame 16. Two screws 7 are distributed left and right, rotatably connected to the rear of the housing 1 and located in front of the fan 6. The fixing frame 10 is welded to the lower left rear side of the housing 1. The motor 9 is bolted to the inside of the fixing frame 10, and the lower end of the left screw 7 is fixedly connected to the output shaft of the motor 9. The pulley assembly 13 is located between the lower ends of the two screws 7. The lifting block 12... The screw 7 is connected to the outside of the screw rod 7. The limit frame 14 is connected to the front side of the two lifting blocks 12 by welding. The movable frame 16 is slidably connected to the limit frame 14. The two first springs 1401 are distributed on the left and right, sleeved on the limit frame 14, and their two ends are fixedly connected to the movable frame 16 and the limit frame 14 respectively. The brush 15 is connected to the rear side of the movable frame 16 by bolts, and its rear edge extends beyond the front edge of the meter 102, so that when the brush 15 contacts the meter 102, there is a certain contact condition between the two, that is, the brush 15 is sufficient to cover the front surface of the meter 102.
[0024] See Figures 5-6As shown, the cooling assembly includes a top plate 17, a piston 1701, a limit rod 18, a second spring 19, a condenser 20, a first water tank 21, a second water tank 22, a connecting pipe 2201, a connecting rod 23, a first one-way valve 25, a second one-way valve 2501, and a cooling pipe 26. Multiple first water tanks 21 are arranged vertically at a certain interval and connected to the rear of the housing 1 by bolts, located in front of the screw 7. The condenser 20 is connected to the rear side of the middle of the first water tanks 21 by bolts. Multiple second water tanks 22 are arranged in four rows and two columns and connected to the housing 1 by bolts. At the rear, and each first water tank 21 is located between every two laterally aligned second water tanks 22, a connecting pipe 2201 is welded between the lower part of the second water tank 22 and the first water tank 21, a limiting rod 18 is welded to the top of the second water tank 22, a top plate 17 is slidably connected to the inside of the second water tank 22, a lifting block 12 is located below the uppermost top plate 17 and contacts it, the top plate 17 slides outside the limiting rod 18, and the upper end of the limiting rod 18 is provided with a circular protrusion, which is located above the top plate 17 to prevent the top plate 17 from falling out of the limiting rod 18, piston 1 701 is welded to the bottom of the top plate 17, and its front, rear, left, and right sides are in sliding contact with the inner wall of the second water tank 22. The second spring 19 is sleeved on the outside of the limiting rod 18, and its two ends are fixedly connected to the top plate 17 and the second water tank 22 respectively. The connecting rod 23 is welded between the vertically aligned multiple top plates 17. Each cooling pipe 26 is welded between the lower parts of every two horizontally aligned second water tanks 22, and is located below and close to the corresponding mounting plate 11. The mounting plate 11 is made of a thermally conductive material, such as copper or aluminum, so that the mounting plate... The heat absorbed by 11 can be absorbed by the cooling pipe 26. The first water tank 21 and the second water tank 22 are both filled with coolant, while the cooling pipe 26 is not filled with coolant, so that the coolant in the first water tank 21 and the second water tank 22 can circulate through the cooling pipe 26. Two first one-way valves 25 are distributed on the left and right sides and are rotatably connected to the left and right ends of the cooling pipe 26. The left first one-way valve 25 is the outlet valve, and the right first one-way valve 25 is the inlet valve. The second one-way valve 2501 is rotatably connected to the connecting pipe 2201, and both second one-way valves 2501 are outlet valves.
[0025] Initially, the second spring 19 is in a stretched state. First, grasp the handle 2 and turn the door 101 forward to open the box 1. Then, install the appropriate number of meters 102 one by one on the mounting plate 11. After installation, turn the door 101 backward to close the box 1. Then, start the fan 6, motor 9, and condenser 20. The fan 6 runs to send outside air into the box 1, allowing the original air inside the box 1 to be discharged through the ventilation window 3, thereby achieving a good ventilation effect and maintaining a dry environment inside the box 1. The output shaft of the motor 9 drives the left screw 7 to rotate, and the left screw 7, through the pulley assembly 13, drives the right screw 7 to rotate, causing the lifting block 12 to move the limit frame 14 downward. The limit frame 14 then moves the movable frame 16 downward, causing the brush 15 to contact the meter 1. The front reading device is squeezed forward, and the first spring 1401 is compressed, applying a backward pressure to the brush 15 to ensure that the brush 15 is in close contact with the reading device to clean the dust. The limit bracket 14 continues to drive the movable bracket 16 to move downward, so that the brush 15 cleans the reading devices of other meters 102. When the lifting block 12 moves downward, it no longer squeezes the top plate 17, and the second spring 19 returns to its original state, causing the top plate 17 to drive the piston 1701 to move downward. When the left piston 1701 moves downward, it squeezes the coolant inside the left second water tank 22, which flows into the first water tank 21 through the left second check valve 2501 and the left connecting pipe 2201. The coolant flowing into the first water tank 21 flows through the right side. The second one-way valve 2501 and the right connecting pipe 2201 flow out into the right second water tank 22. When the right piston 1701 moves downward, it squeezes the coolant inside the right second water tank 22, which flows into the cooling pipe 26 through the right first one-way valve 25, allowing the cooling pipe 26 to absorb the heat generated by the meter 102 during operation. When the brush 15 moves downward to its limit position, the output shaft of the control motor 9 reverses, driving the left screw 7 to reverse. The left screw 7 then drives the right screw 7 to reverse through the pulley assembly 13, causing the lifting block 12 to drive the limit frame 14 to move upward. The limit frame 14 drives the movable frame 16 to move upward, allowing the brush 15 to perform a secondary cleaning. When the lifting block 12 moves upward and resets, it squeezes the top plate 17 on the uppermost side to move upward. Spring 19 is stretched, and the top plate 17 drives piston 1701 to move upward. When the left piston 1701 moves upward, coolant inside cooling pipe 26 is drawn into the left second water tank 22 through the left first check valve 25. When the right piston 1701 moves upward, coolant inside the left second water tank 22 is drawn into the first water tank 21 through the left second check valve 2501 and the left connecting pipe 2201. Simultaneously, coolant inside the first water tank 21 is drawn into the right second water tank 22 through the right second check valve 2501 and the right connecting pipe 2201. The drawn-in coolant flows into cooling pipe 26 through the right first check valve 25, thus achieving coolant circulation.The condenser 20 continuously cools the coolant inside the first water tank 21, allowing the coolant inside the cooling pipe 26 to continuously absorb the heat generated by the meter 102 during operation, thus preventing the meter 102 from overheating.
[0026] It is worth noting that the topmost top plate 17 is restrained by the connecting rod 23 to hold the other top plates 17 in place, ensuring that the movements of all top plates 17 are synchronized.
