Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a dehumidification, moisture-proof, and circulating ventilation component inside a distribution box. Background Technology

[0002] The dehumidification and moisture-proof circulating ventilation component inside the distribution box mainly consists of a fan, a humidity sensor, a controller, and an air duct. The humidity sensor monitors the humidity inside the box in real time. When the humidity exceeds the set threshold, the controller starts the fan and guides the air circulation through the air duct to exhaust the humid air and introduce dry air, forming a ventilation cycle.

[0003] The dehumidification and moisture-proof circulating ventilation components inside the distribution box adopt a bolt-fixed connection structure to ensure installation stability and vibration resistance. The fan is bolted to the side wall of the box through an L-shaped galvanized steel plate bracket. The bracket has a pre-set elongated hole to facilitate adjustment of the installation position. Rubber washers are placed at the bolt holes to prevent loosening and reduce noise, but most of the bolts are embedded structures.

[0004] The dehumidification and moisture-proof circulating ventilation components inside the distribution box are embedded and fixed to the distribution box cabinet. The screws are hidden under the sealing strip or integrated circuit board. It is necessary to remove the surrounding electrical components to access the installation interface. This results in the need to disconnect the entire power supply during maintenance, which consumes a lot of time and affects the efficiency of equipment operation and maintenance. Therefore, the dehumidification and moisture-proof circulating ventilation components inside the distribution box are proposed to solve the above problems. Utility Model Content

The outer wall of the limiting plate 18 is slidably connected to... The fixed frame 12 is attached to the outside of the fixed frame 12, which provides a sliding track for the limiting plate 18 to ensure smooth movement of the limiting plate 18. A sliding rod 19 is slidably connected inside the limiting plate 18 and slides within it. A fixed rod 21 is rotatably connected to the outside of the sliding rod 19 and rotates as the sliding rod 19 slides. A push rod 17 is slidably connected to the outside of the fixed frame 12, with one end of the push rod 17 fixedly connected to the outside of the limiting plate 15, transmitting external force to the limiting plate 15 through the push rod 17. The drawer 5 is slidably connected inside the cabinet 1, and a locking block 22 is fixedly connected to the outside of the drawer 5. The top of the fixing rod 21 engages with the inside of the locking block 22. The locking block 22 engages with the top of the fixing rod 21 to lock the drawer 5. A fan 6 is fixedly connected inside the drawer 5. When the fan 6 is powered on, it generates airflow to accelerate the air circulation inside the cabinet 1, reduce humidity, and achieve dehumidification and moisture-proof function. A fixing post 20 is fixedly connected inside the limiting plate 18. The other end of the fixing post 20 is fixedly connected to the inside of the cabinet 1.

When rotating plate 7 rotates, upper bolt 9 is inserted into the lock hole at the top of cabinet 1. The other end of rotating plate 7 is rotatably connected to a lower bolt 8, which is inserted into the lock hole at the bottom of cabinet 1 as rotating plate 7 rotates, forming a two-way locking with upper bolt 9, enhancing the sealing effect of cabinet door 2. Two pneumatic push rods 10 are fixedly connected to the outside of cabinet 1. The driving ends of the two pneumatic push rods 10 are fixedly connected to a top plate 4. Pneumatic push rods 10 drive the top plate 4 to move. When the weather is sunny, pneumatic push rods 10 push the top plate 4 upward to facilitate ventilation. When it rains, pneumatic push rods 10 drive the top plate 4 downward to prevent rainwater from entering.

[0036] Working principle: The fan 6 in the distribution box will be damaged after long-term use and needs to be replaced. Press the drawer 5, and the drawer 5 will push the push rod 17 to move. The push rod 17 will drive the limiting plate 15 to move. The movement of the limiting plate 15 will cause the limiting post 16 to drive the swing rod 13 to swing. Thus, the limiting post 16 will move along the slot on the limiting plate 15. The limiting plate 15 will compress the spring 14. The spring 14 will generate elastic potential energy, which will push the limiting plate 15 to generate a reverse force, causing the drawer 5 to pop out, making it easy to replace the fan 6. After replacement, push the drawer 5 in. The drawer 5 will push the push rod 17. The push rod 17 will push the limiting plate 15. The limiting plate 15 will cause the limiting post 16 to be locked in the slot of the limiting plate 15. At the same time, the fixing rod 21 will be locked on the locking block 22 for fixation.

[0037] When ventilation is needed, activate pneumatic push rod 23. Pneumatic push rod 23 pulls linkage rod 26 to move. Linkage rod 26 drives rotating rod 25 to rotate. Rotating rod 25 drives multiple rotating shafts 24 to rotate. Rotating shafts 24 drive louvers 3 to swing. At the same time, activate pneumatic push rod 10. Pneumatic push rod 10 pushes top plate 4 upward to allow ventilation on the sides and top. When it rains, activate pneumatic push rod 23 to pull linkage rod 26 to close louvers 3. At the same time, activate pneumatic push rod 10. Pneumatic push rod 10 pulls top plate 4 downward to cover cabinet 1 and prevent rainwater from entering. Turn handle 11. Handle 11 drives rotating plate 7 to rotate. Rotating plate 7 drives lower bolt 8 and upper bolt 9 to move up and down to lock cabinet 1 and cabinet door 2.
