Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution box technology, and in particular to an outdoor low-voltage power distribution box with protective function. Background Technology

[0002] The low-voltage distribution cabinet is a power distribution system with a rated current of AC 50Hz and a rated voltage of 380V, used for power conversion and control of power, lighting, and distribution. Chinese Patent CN221282668U discloses an outdoor low-voltage power distribution box with protective function, including a distribution box body and protective components. The front end of the distribution box body is rotatably mounted with a distribution box door, and the four corners of the distribution box body are staggered with mounting holes. The protective components for protecting the distribution box door are installed inside the mounting holes. The protective components include a damping sleeve, a fixing hole, a buffer spring, a damping slide rod, and a protective plate. The outer wall of the end of the damping sleeve is provided with a fixing hole, and a buffer spring is fixedly installed inside the damping sleeve. A damping slide rod is fixedly installed on the top of the buffer spring, and the damping slide rod is elastically connected to the damping sleeve through the buffer spring. A protective plate is fixedly installed on the front end of the damping slide rod. This outdoor low-voltage power distribution box with protective functions can not only prevent the cabinet door from being squeezed and deformed, but also allow the protective components to be disassembled as needed, improving ease of use.

[0003] The aforementioned patents lack ventilation and heat dissipation functions during use. In summer, when exposed to direct sunlight outdoors, the internal components are prone to overheating. In addition, the patents lack moisture-proof functions, making the electrical components susceptible to moisture damage from humid air during rainy days. Therefore, in view of the above situation, there is an urgent need to develop an outdoor low-voltage power distribution box with good ventilation and heat dissipation, easy disassembly and cleaning, and good moisture-proof performance to prevent electrical components from getting damp, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor low-voltage power distribution box with protective functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An outdoor low-voltage power distribution box with protective functions includes a chassis, a door, a ventilation and heat dissipation mechanism, a rainproof mechanism, and a moisture-proof mechanism. The door is rotatably connected to the front of the chassis via a hinge. A ventilation and heat dissipation mechanism is provided on both sides of the chassis, and a rainproof mechanism is provided on the outer side of each ventilation and heat dissipation mechanism. A moisture-proof mechanism is detachably installed inside the chassis. The ventilation and heat dissipation mechanism includes a ventilation and dustproof net, a limiting block, and an anti-fall-off mechanism. The ventilation and dustproof net is inserted into the side wall of the chassis. A limiting block is fixed on both the left and right sides of the ventilation and dustproof net, and an anti-fall-off mechanism is provided above each limiting block.

[0007] Preferably, the anti-fall-off mechanism includes: a connecting block, a pin, and a spring. The connecting block is fixed to the outer wall of the chassis, and a pin that penetrates the limiting block is installed on the connecting block. A spring is provided on the upper half of the pin.

[0008] Preferably, the pin is slidably connected to the adapter block and the limiting block.

[0009] Preferably, the upper end of the spring is fixed to the pin and the lower end is fixed to the adapter block.

[0010] Preferably, the moisture-proof mechanism includes: a crossbar, magnetic rings, sliding sleeves, extension rods, and storage shells. Magnetic rings are fixed at both ends of the crossbar and are attracted to the inner wall of the chassis. Multiple sliding sleeves are slidably installed on the crossbar. An extension rod is fixed to the lower side of each sliding sleeve. Multiple storage shells are fixed to each extension rod, and desiccant is stored inside each storage shell.

[0011] Preferably, the rain-shielding mechanism includes a rain cover, a rotating shaft, and a magnetic strip. The upper end of the rain cover is fixed with a rotating shaft, which is rotatably connected to the chassis. A magnetic strip is fixed on the rain cover and adsorbed onto the outer wall of the chassis.

[0012] Preferably, the side of the chassis is provided with a first lock hole, and the side of the chassis door is provided with a second lock hole.

[0013] The beneficial effects of this utility model are as follows: This outdoor low-voltage power distribution box with protective function allows air to enter and exit through the ventilation and dustproof net during use, thereby dissipating heat from inside the box. Simultaneously, a rain cover protects the ventilation and heat dissipation mechanism from rainwater ingress. After a period of use, the rain cover can be lifted upwards, the pin removed from the limit block, and the ventilation and dustproof net removed from the box for cleaning. The sliding sleeve moves the extension rod and storage shell, adjusting the positions of multiple storage shells to distribute them throughout the box, ensuring more thorough contact between the desiccant and the air inside, resulting in better dehumidification. After a period of use, the moisture-proof mechanism can be removed from the box, and the desiccant in the storage shells can be replaced. In summary, this utility model offers good ventilation and heat dissipation, is easy to disassemble and clean, and has good moisture-proof performance, preventing electrical components from getting damp.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] See Figures 1-7 In this embodiment of the present invention, an outdoor low-voltage power distribution box with protective function includes a chassis 1, a door 2, a ventilation and heat dissipation mechanism 3, a rainproof mechanism 4, and a moisture-proof mechanism 5. The front side of the chassis 1 is rotatably connected to the door 2 via a hinge. A first lock hole 101 is provided on the side of the chassis 1, and a second lock hole 201 is provided on the side of the door 2. By passing a lock through the first lock hole 101 and the second lock hole 201, the chassis 1 and the door 2 are locked to prevent unauthorized access. Inside the chassis 1... Electrical components 102 are installed. A ventilation and heat dissipation mechanism 3 is provided on both sides of the chassis 1. Airflow enters and exits through the ventilation and heat dissipation mechanism 3 to dissipate heat inside the chassis 1. A rainproof mechanism 4 is provided on the outside of each ventilation and heat dissipation mechanism 3 to block rainwater and prevent rainwater from entering the chassis 1 through the ventilation and heat dissipation mechanism 3 when it rains. A moisture-proof mechanism 5 is detachably installed inside the chassis 1 to absorb moisture inside the chassis 1 and prevent the electrical components 102 from getting damp.

[0026] The ventilation and heat dissipation mechanism 3 includes: a ventilation and dustproof net 301, a limiting block 302, and an anti-fall-off mechanism 303. The ventilation and dustproof net 301 is inserted into the side wall of the chassis 1. A limiting block 302 is fixed on both the left and right sides of the ventilation and dustproof net 301. An anti-fall-off mechanism 303 is provided above each limiting block 302. The anti-fall-off mechanism 303 includes: a connecting block 3031, a pin 3032, and a spring 3033. The connecting block 3031 is fixed to the outer wall of the chassis 1. A through-hole is installed on the connecting block 3031. The pin 3032 of the limiting block 302 is slidably connected to the adapter block 3031 and the limiting block 302. The upper half of the pin 3032 is provided with a spring 3033. The upper end of the spring 3033 is fixed to the pin 3032 and the lower end is fixed to the adapter block 3031. In use, air enters and exits through the ventilation and dustproof net 301, thereby dissipating the heat inside the chassis 1 to the outside. After a period of use, the pin 3032 is pulled out from the limiting block 302, and the ventilation and dustproof net 301 is pulled off the chassis 1 for cleaning.

[0027] The rain-proof mechanism 4 includes: a rain cover 401, a rotating shaft 402, and a magnetic strip 403. The upper end of the rain cover 401 is fixed with the rotating shaft 402, which is rotatably connected to the chassis 1. The rain cover 401 is fixed with a magnetic strip 403 that is attracted to the outer wall of the chassis 1. During normal use, the magnetic strip 403 is attracted to the chassis 1, and the rain cover 401 covers the ventilation and heat dissipation mechanism 3 to prevent rainwater from entering.

[0028] The moisture-proof mechanism 5 includes: a crossbar 501, a magnetic ring 502, a sliding sleeve 503, an extension rod 504, and a storage shell 505. Magnetic rings 502 are fixed to both ends of the crossbar 501, and the magnetic rings 502 are adsorbed onto the inner wall of the casing 1. Multiple sliding sleeves 503 are slidably mounted on the crossbar 501. An extension rod 504 is fixed to the lower side of each sliding sleeve 503, and multiple storage shells 505 are fixed to each extension rod 504. Each storage shell 505 stores desiccant. During use, sliding the sliding sleeves 503 moves the extension rods 504 and storage shells 505, adjusting the positions of the multiple storage shells 505 so that they are dispersed within the casing 1, allowing for more thorough contact between the desiccant and the air inside the casing 1, thus improving the dehumidification effect. After a period of use, the moisture-proof mechanism 5 can be removed from the casing 1, and the desiccant in the storage shells 505 can be replaced.

[0029] Working principle: This outdoor low-voltage power distribution box with protective function allows air to enter and exit through the ventilation and dustproof mesh 301, thereby dissipating heat from inside the chassis 1. Simultaneously, the rain cover 401 covers the ventilation and heat dissipation mechanism 3 to prevent rainwater from entering. After a period of use, the rain cover 401 is lifted upwards, the pin 3032 is pulled out from the limit block 302, and the ventilation and dustproof mesh 301 is removed from the chassis 1 for cleaning. The sliding sleeve 503 moves the extension rod 504 and the storage shell 505, adjusting the positions of the multiple storage shells 505 so that they are distributed throughout the chassis 1, allowing for more thorough contact between the desiccant and the air inside the chassis 1, resulting in better dehumidification. After a period of use, the moisture-proof mechanism 5 is removed from the chassis 1, and the desiccant inside the storage shell 505 is replaced.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
