[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The power distribution cabinet with a waterproof structure is provided with a double-axis motor, a first bevel gear, a second bevel gear, a threaded rod, a moving block, a baffle, a side plate and a heat dissipation port. By starting the double-axis motor to rotate the rotating shaft, the meshing of the first bevel gear and the second bevel gear drives the threaded rod to rotate, so that the moving block can move along the threaded rod through the threaded sleeve, prompting the baffle to slide in the side plate, so that the side plate and the heat dissipation port on the baffle are misaligned, so that the heat dissipation port on the side plate is closed by the baffle, and accumulated water is prevented from flowing into the interior of the cabinet from the heat dissipation port. Usually, the heat dissipation port on the side plate and the baffle are in an overlapping and aligned state, thereby ensuring normal ventilation in the cabinet and preventing heat accumulation from affecting work.

[0014] 2. The power distribution cabinet with a waterproof structure is provided with an installation frame, a snap plate, a torsion spring, a bellows, a driving motor, a fan blade and a fixing groove. By rotating the snap plate, a worker can push the bellows into the installation frame. When the snap plate rotates, the snap plate will twist the torsion spring, thereby driving the snap plate to rotate through the rotation of the torsion spring, so that one end of the snap plate is inserted into the fixing groove to fix the bellows in the installation frame to prevent the bellows from sliding during work. The operation is simple and convenient for the worker to install and disassemble the bellows. The driving motor will rotate the fan blades, thereby accelerating the circulation speed of the air inside the cabinet through the rotating fan blades, so that the heat generated by the work in the distribution cabinet is dissipated from the heat dissipation port to prevent high temperature from damaging the electronic components.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a power distribution cabinet with a waterproof structure, including a cabinet body 1, side panels 2 are connected to both sides of the cabinet body 1, heat dissipation ports 17 are provided on the side panels 2 and the baffles 16 and the positions correspond to each other, the baffles 16 slide inside the side panels 2, and a rain shield 27 is connected to the position where the heat dissipation ports 17 are provided on the side panels 2. When the baffles 16 slide inside the side panels 2, the baffles 16 and the heat dissipation ports 17 on the side panels 2 will be misaligned, so that the baffles 16 are used to block the heat dissipation ports 17 on the side panels 2 to prevent water from entering, and the rain shield 27 can prevent rainwater from drifting into the cabinet body 1 from the heat dissipation ports 17.

[0022] A cabinet door 3 is rotatably connected to the front of the cabinet body 1, an anti-skid pad 4 is connected to the bottom of the cabinet body 1, and anti-skid patterns are arranged under the anti-skid pad 4. Support blocks 33 are connected to both sides of the anti-skid pad 4. The anti-skid pad 4 increases the friction between the cabinet body 1 and the ground to prevent the cabinet body 1 from sliding during work, and the support blocks 33 can assist in supporting the cabinet body 1 to prevent the cabinet body 1 from tilting.

[0023] A mounting frame 5 is connected to the rear of the cabinet 1, and a limiting plate 29 is connected to the mounting frame 5. Buckle plates 30 are rotatably connected to both sides of the mounting frame 5. Torsion springs 31 are connected to both sides of the buckle plates 30. One end of the torsion spring 31 is connected to the mounting frame 5. When the bellows 6 is pushed into the mounting frame 5, the bellows 6 will eventually contact the limiting plate 29, thereby blocking the bellows 6 and preventing the bellows 6 from sliding out and falling from one side of the mounting frame 5. The restriction of the torsion spring 31 can prevent the buckle plate 30 from rotating accidentally.

[0024] The cabinet 1 is provided with a bellows 6 through a mounting frame 5, a partition 7 is connected inside the cabinet 1, a mounting plate 8 is connected inside the cabinet 1, a dual-axis motor 9 is installed on the mounting plate 8, a rotating shaft 10 is connected to the output shaft of the dual-axis motor 9, one end of the rotating shaft 10 is connected to a first bevel gear 11, the first bevel gear 11 is meshedly connected to a second bevel gear 12, a threaded rod 13 is connected to the second bevel gear 12, a moving block 14 is installed on the threaded rod 13, a threaded sleeve 15 is installed on the moving block 14, and a threaded sleeve 16 is connected to the moving block 14. A baffle 16 is connected, an auxiliary block 18 is connected to the baffle 16, a slide rod 19 is connected inside the cabinet 1, the auxiliary block 18 slides on the slide rod 19, the threaded sleeve 15 is threadedly connected to the threaded rod 13, and the threaded rod 13 is rotatably connected to the inside of the cabinet 1, a plurality of slide grooves 28 are opened on one side of the side panel 2, the moving block 14 and the auxiliary block 18 both slide in the slide grooves 28, and the sliding of the baffle 16 is guided by the slide rod 19, so that the baffle 16 can move smoothly and avoid the baffle 16 from tilting when moving.

[0025] A baffle 20 is connected to the bellows 6, a cover shell 21 is connected inside the bellows 6, an air inlet 22 is provided on the cover shell 21, a dustproof plate 23 is connected to the cover shell 21, a fixing frame 24 is connected inside the cover shell 21, a driving motor 25 is installed on the fixing frame 24, and a fan blade 26 is connected to the output shaft of the driving motor 25. Fixed grooves 32 are provided on both sides of the bellows 6, and the snap plate 30 is L-shaped and one end is inserted into the fixed groove 32. The baffle 20 can prevent rainwater from flowing into the bellows 6 to prevent rainwater from causing a circuit breaker. The snap plate 30 is inserted into the fixed groove 32, thereby cooperating with the limit plate 29 to lock the bellows 6 to prevent the bellows 6 from sliding.

[0026] The working principle of the utility model is:

[0027] The staff first rotates the snap plate 30 so that the bellows 6 can be smoothly pushed into the installation frame 5. The snap plate 30 will twist the torsion spring 31 when it rotates. When the bellows 6 completely enters the installation frame 5, the torsion spring 31 rotates, thereby driving the snap plate 30 to rotate, so that one end of the snap plate 30 is inserted into the fixing groove 32, and the bellows 6 is fixed in the installation frame 5. By starting the drive motor 25 to rotate the fan blades 26, the rotating fan blades 26 are used to accelerate the circulation speed of the air inside the cabinet 1, so that the distribution cabinet works. The generated heat is quickly dissipated from the heat dissipation port 17, and when heavy rain occurs and water accumulates, the dual-axis motor 9 is started to rotate the rotating shaft 10, thereby driving the threaded rod 13 to rotate through the engagement of the first bevel gear 11 and the second bevel gear 12, so that the moving block 14 can move along the threaded rod 13 through the threaded sleeve 15, prompting the baffle plate 16 to slide in the side plate 2, causing the side plate 2 and the heat dissipation port 17 on the baffle plate 16 to be misaligned, thereby closing the heat dissipation port 17 on the side plate 2 through the baffle plate 16 to prevent water from entering.
