[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 6 , the present utility model provides the following technical solutions:

[0029] A ring main unit switchgear includes a cabinet body 1, a top cover 2, and a cabinet door 3. The top cover 2 is fixedly connected to the top of the cabinet body 1, and the cabinet door 3 is hinged to one end of the front side of the cabinet body 1;

[0030] The cabinet body 1 is provided with two symmetrically distributed storage structures. The storage structure includes slide rails 5 fixedly connected to the bottom and side of the cabinet body 1. A pulley 6 is rotatably connected to the outer side of the front end of the slide rail 5 located at the bottom of the cabinet body 1. An installation plate 7 is slidably connected to the inner side of the slide rail 5. A plurality of sliders 8 corresponding to the slide rails 5 one by one are fixedly connected to the outer side of the installation plate 7. The installation plate 7 is slidably connected to the inner side of the slide rail 5 through the sliders 8, and the bottom of the installation plate 7 is slidably connected to the pulley 6.

[0031] There are two installation plates 7 inside the cabinet body 1. A wiring cabinet 9 and a switch cabinet 10 are respectively fixedly connected to the inside of the two installation plates 7. Handles 11 are fixedly connected to the front sides of the wiring cabinet 9 and the switch cabinet 10.

[0032] A partition board 12 is fixedly connected to the middle inside the cabinet body 1. The partition board 12 divides the inside of the cabinet body 1 into two symmetric spaces. The installation plate 7, the wiring cabinet 9, and the handle 11 are respectively located in the two symmetric spaces inside the cabinet body 1. A plurality of vertically equally spaced exhaust grilles 4 are provided on both sides of the cabinet body 1. The plurality of vertically equally spaced exhaust grilles 4 form a ventilation window.

[0033] A plurality of equally spaced ventilation grilles 13 are provided inside the partition board 12. The ventilation grilles 13 communicate the two symmetric spaces inside the cabinet body 1 with each other.

[0034] A fixing member 14 is fixedly connected to the middle inside the partition board 12. Symmetrically distributed elastic pieces 15 are fixedly connected to both sides of the fixing member 14. One ends of the two elastic pieces 15 away from the fixing member 14 are respectively in contact with the sides of the wiring cabinet 9 and the switch cabinet 10 close to the partition board 12.

[0035] There are two symmetrically distributed wire routing holes on the rear side of the cabinet body 1, and a wire routing pipe 16 is fixedly connected inside the routing holes. One end of the wire routing pipe 16 away from the handle 11 is fixedly connected to the wiring cabinet 9 and the wiring connection at the rear end of the switch cabinet 10 respectively. One end of the wire routing pipe 16 away from the wiring cabinet 9 and the switch cabinet 10 is fixedly connected with a fixing ring 17, and the fixing ring 17 is located outside the cabinet body 1.

[0036] Air inlets 18 are provided on both sides of the bottom of the top cover 2, and a ventilation fan 19 is fixedly connected to the inner bottom of the top cover 2, and the top cover 2 is communicated with the inside of the cabinet body 1 through the ventilation fan 19.

[0037] Embodiment 2:

[0038] On the basis of Embodiment 1, its specific working principle is as follows:

[0039] For this ring main unit switchgear, the mounting plate 7 slides on the slide rail 5 through the slider 8, so that the mounting plate 7 can slide inside the cabinet body 1. By pulling the handle 11, the wiring cabinet 9 and the switch cabinet 10 are driven to slide inside the cabinet body 1, and then the mounting plate 7 slides inside the cabinet body 1. When the mounting plate 7 slides outside the cabinet body 1, the wiring cabinet 9 and the switch cabinet 10 will be driven to move outside the cabinet body 1 through the mounting plate 7, so as to facilitate the maintenance of the wiring cabinet 9 and the switch cabinet 10. When the mounting plate 7 slides or is stationary, the pulley 6 will support the bottom of the mounting plate 7 and rotate following the mounting plate 7 during the sliding process of the mounting plate 7;

[0040] When the mounting plate 7 slides to the outside of the cabinet body 1, the slider 8 at the bottom of the mounting plate 7 will be in contact with the inner part of the front side of the cabinet body 1 at this time, so as to limit the sliding position of the slider 8, and then limit the sliding position of the mounting plate 7. At the same time, a plurality of equally spaced threaded holes are provided on the side edges of the bottom of the mounting plate 7, and the connection holes of the wiring cabinet 9 and the switch cabinet 10 with different sizes are adapted through the plurality of threaded holes, so as to fix the wiring cabinet 9 and the switch cabinet 10 with different sizes;

[0041] Through the setting of the ventilation grid 13 inside the partition board 12, the two sides inside the cabinet body 1 are in a connected state, enabling the air to circulate completely inside the cabinet body 1, improving the heat dissipation efficiency of the wiring cabinet 9 and the switch cabinet 10 when they are inside the cabinet body 1. The elastic pieces 15 on both sides of the fixing piece 14 support the wiring cabinet 9 and the switch cabinet 10. At the same time, the elastic pieces 15 always exert a clamping force on the wiring cabinet 9 and the switch cabinet 10 towards the mounting piece 7. When installing the wiring cabinet 9 and the switch cabinet 10 with different sizes inside the mounting piece 7, through the deformation of the elastic pieces 15, the elastic pieces 15 always fit with the wiring cabinet 9 and the switch cabinet 10, stabilizing the installation state of the wiring cabinet 9 and the switch cabinet 10. At the same time, through the deformation of the elastic pieces 15, the wiring cabinet 9 and the switch cabinet 10 have a certain seismic resistance effect. The elastic pieces 15 exert a force perpendicular to the slider 8 and the slide rail 5 on the wiring cabinet 9 and the switch cabinet 10, applying damping to the sliding of the mounting piece 7 through the slider 8 inside the slide rail 5, thereby restricting the sliding of the mounting piece 7;

[0042] The external connection cables of the wiring cabinet 9 and the switch cabinet 10 both extend to the outside of the cabinet body 1 after passing through the wire duct 16 and the fixing ring 17. The wire duct 16 is set as a corrugated pipe structure, enabling the wire duct 16 to have good flexibility. When installing the wiring cabinet 9 and the switch cabinet 10 with different sizes inside the mounting piece 7, through the contraction of the wire duct 16 itself, the external connection cables of the wiring cabinet 9 and the switch cabinet 10 are always located inside the wire duct 16 to protect them;

[0043] By starting the operation of the ventilation fan 19 at the bottom of the top cover 2, the ventilation fan 19 sucks the external air into the inside of the top cover 2 through the air inlet 18, and sends the air into the cabinet body 1 through the ventilation fan 19. After the air circulates, it is discharged from the cabinet body 1 through the exhaust grid 4, dissipating heat and cooling the wiring cabinet 9 and the switch cabinet 10.

[0044] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
