Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor power distribution cabinets, in particular to an outdoor power distribution cabinet with good waterproof effect. Background Art

[0002] Outdoor power distribution cabinet is a device used for power distribution and control of outdoor electrical equipment, usually used in outdoor power distribution system. It has waterproof, dustproof, anti-corrosion and other characteristics, which can protect electrical equipment from the influence of external environment and ensure the safe and stable operation of electrical system.

[0003] After checking the public (announcement) number: CN210723751U, a waterproof outdoor power distribution cabinet is disclosed. This technology discloses "including a base, the top outer wall of the base is fixed with an anti-seepage pad by screws, and the top outer wall of the anti-seepage pad is fixed with a cabinet by screws, and the top outer wall of the cabinet is fixed with a top cover by screws, one side outer wall of the top cover is fixed with a rainproof canopy by screws, and the bottom outer wall of the rainproof canopy is fixed with a camera by screws, one side inner wall of the cabinet is connected with a cabinet door by a hinge, and a sealing gasket of an annular structure is bonded to the edge of one side outer wall of the cabinet door, one side outer wall of the cabinet is opened with a heat dissipation hole, and the inner wall of the heat dissipation hole is fixed with a dustproof net by screws, and the outer wall of the heat dissipation hole is fixed with an inclined rain shield by screws. The utility model can play an all-round waterproof effect on the cabinet, prevent rainwater from entering the cabinet and causing the internal parts of the cabinet to burn out, and improve the service life of the power distribution cabinet";

[0004] However, in the above-mentioned comparative documents, the cabinet door and the distribution cabinet are sealed by a sealing gasket. Since the sealing gasket may be deformed or squeezed to a certain extent when subjected to pressure, the sealing gasket cannot adjust the sealing state when subjected to pressure during the sealing process between the cabinet door and the distribution cabinet, and has poor pressure resistance. Secondly, the sealing gasket is usually suitable for sealing surfaces of specific shapes. If a more complex or irregular sealing surface is encountered, a good sealing effect may not be achieved. At the same time, it may be inconvenient to seal the joints on the top of the distribution cabinet when it rains, which may cause water to penetrate from the top of the distribution cabinet.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

At the bottom of the plate 6, two connecting pipes 8 are provided. The two connecting pipes 8 are symmetrically distributed around the central axis of the mounting plate 6. The connecting pipe 8 is connected to the first airbag ring 5. The connecting pipe 8 connects the second airbag ring 7 with the gas inside the first airbag ring 5. After the first airbag ring 5 expands, the closing door 2 closes the front side of the distribution cabinet body 1. At this time, part of the first airbag ring 5 is located inside the first groove 3, and the first airbag ring 5 is in a compressed state, thereby increasing the sealing effect between the distribution cabinet body 1 and the closing door 2. After the second airbag ring 7 expands, it fits with the inner top wall of the distribution cabinet body 1, thereby preventing water from penetrating from the top of the distribution cabinet body 1, thereby increasing the waterproof effect of the distribution cabinet body 1.

[0028] Reference Figure 2-3 The inner wall of the distribution cabinet body 1 is fixedly connected with a horizontal plate 19, and the horizontal plate 19 is located on the left inner wall of the distribution cabinet body 1. The top of the horizontal plate 19 is fixedly connected with an air pump 9, and the air outlet of the air pump 9 is fixedly connected with an air outlet pipe 10. The air outlet pipe 10 is fixedly passed through the bottom of the mounting plate 6. The air outlet pipe 10 is connected with the second air bag ring 7. A one-way valve is arranged inside the air outlet pipe 10. After the air pump 9 is running, the gas is transmitted to the inside of the second air bag ring 7 through the air outlet pipe 10, so that the second air bag ring 7 and the first air bag ring 5 slowly expand.

[0029] Reference Figure 2-3 The inner wall of the power distribution cabinet body 1 is fixedly connected with a support plate 11, which is arranged in an inclined shape. The top of the support plate 11 is fixedly connected to the bottom of the horizontal plate 19. The support plate 11 obliquely supports the horizontal plate 19 to increase the stability of the operation of the vacuum pump 9.

[0030] Reference Figure 4 The inner bottom wall of the power distribution cabinet body 1 is provided with a heat dissipation groove 12, and the heat dissipation groove 12 is located at the bottom center of the power distribution cabinet body 1. The power distribution cabinet body 1 is provided with a heat dissipation hole 13 through the heat dissipation groove 12. The heat dissipation groove 12 and the heat dissipation hole 13 facilitate the dissipation of heat inside the power distribution cabinet body 1.

[0031] Reference Figure 1 and Figure 4The bottom of the distribution cabinet body 1 is fixedly connected with an upper steel frame 14, the bottom of the upper steel frame 14 is fixedly connected with a vertical steel 15, the bottom of the vertical steel 15 is fixedly connected with a lower steel frame 16, the upper steel frame 14, the vertical steel 15 and the lower steel frame 16 are all made of steel. The upper steel frame 14, the vertical steel 15 and the lower steel frame 16 support the distribution cabinet body 1 to a certain height, so as to facilitate the downward discharge of the internal heat of the distribution cabinet body 1.

The end of the exhaust pipe 17 away from the first airbag ring 5 is threadedly connected with a closing plug 18. After the closing plug 18 moves to separate from the exhaust pipe 17, the gas inside the first airbag ring 5 and the second airbag ring 7 is discharged through the exhaust pipe 17.

[0033] Working principle: First, move the switch cabinet body 1 to a suitable position outdoors, and start the vacuum pump 9. The gas is transmitted to the inside of the second airbag ring 7 through the outlet pipe 10. The second airbag ring 7 then expands to fit with the seam of the inner bottom wall of the switch cabinet body 1 to prevent water from flowing into the inside of the switch cabinet body 1 through the seam at the top of the switch cabinet body 1. Part of the gas flows to the inside of the first airbag ring 5 through the connecting pipe 8. The first airbag ring 5 then expands. After the first airbag ring 5 located inside the second groove 4 is filled, the closing door 2 applies external force to the process of closing the outside of the switch cabinet body 1, so that the expanded first airbag ring 5 is The airbag ring 5 is located between the first groove 3 and the second groove 4 and is in a compressed state, thereby increasing the sealing between the distribution cabinet body 1 and the closed door 2. At the same time, when the closed door 2 is opened, the first airbag ring 5 applies an outward elastic force to the closed door 2, thereby increasing the convenience of opening the closed door 2 and avoiding the closed door 2 from being stuck on the outer wall of the distribution cabinet body 1. When the first airbag ring 5 and the second airbag ring 7 need to be deflated, the sealing plug 18 moves to separate from the exhaust pipe 17, and the gas inside the first airbag ring 5 and the second airbag ring 7 is discharged through the exhaust pipe 17, thereby facilitating the contraction of the first airbag ring 5 and the second airbag ring 7.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
