Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to a power distribution automation ring network cabinet. Background Art

[0002] The power distribution automation ring network cabinet is an important equipment widely used in the power distribution system. It has the advantages of compact structure, small space occupation, ability to connect and switch multiple power supply lines and multiple outgoing line circuits, and good sealing. The installation environment of the power distribution automation ring network cabinet is divided into indoor and outdoor. For outdoor ring network cabinets, it is necessary to improve the protection performance of the ring network cabinet, among which the most critical is waterproof. On rainy days, even if rainwater does not directly enter the ring network cabinet, moisture will have a certain impact on the ring network cabinet. The existing outdoor ring network cabinet will reduce the contact with water by increasing the thickness of the bottom plate or raising the ring network cabinet. As for the impact on the ring network cabinet, for the former, rainwater will seep into the gap between the ring network cabinet and the ground, and since the gap between the ring network cabinet and the ground is extremely small, the evaporation rate of rainwater is slow, which will cause the bottom of the ring network cabinet to be in a wet state for a long time, causing the bottom of the ring network cabinet to be corroded and the increased humidity to affect the insulation performance of the internal electrical components. For the latter, the height of the ring network cabinet after being raised is relatively fixed, and it is not convenient to adjust the height of the ring network cabinet according to the depth of rainwater. When the depth of rainwater is higher than the raised height of the ring network cabinet, the rainwater will contact the ring network cabinet, which will also have an adverse effect on the ring network cabinet.

[0022] Connecting shafts 221 are provided on both sides of the handle 22, and a connecting block 321 is provided on the top of the rocker 32. The two connecting shafts 221 are rotatably connected to the connecting block 321; through the connection between the connecting shafts 221 and the connecting block 321, the height of the two rockers 32 can be adjusted at the same time by lifting and pressing down the handle 22.

[0023] The fixing seat 1 3 and the fixing seat 2 4 do not contact the ring network cabinet body 1, and the two fixing seats 1 3 are symmetrical to each other; the fixing seat 1 3 and the fixing seat 2 4 will not interfere with the lifting and lowering of the ring network cabinet body 1, and the two fixing seats 2 4 are also symmetrical to each other.

[0024] The working principle and use process of the present invention are as follows: when the handle 22 is lifted upward, the two rocking arms 32 will be lifted upward at the same time, so that the hydraulic oil 411 inside the storage chamber 41 can be drawn into the interior of the empty slot 1 31 through the flow channel 3 44, the connecting pipe 1 332 and the flow channel 1 33, and then the two rocking arms 32 are pressed down by the handle 22, so that the hydraulic oil 411 inside the empty slot 1 31 can be pushed into the interior of the cavity 2 42 through the flow channel 2 34, the connecting pipe 2 341 and the flow channel 4 45. When the hydraulic oil 411 inside the cavity 2 42 increases, the pressure of the hydraulic oil 411 inside the cavity 2 42 will increase, so that the support column 111 can be pushed upward by the hydraulic pressure, and the two support columns 111 can be moved upward. Adjusting the distance between the ring network cabinet body 1 and the base plate 2 is beneficial to adjusting the height of the ring network cabinet body 1 according to the depth of rainwater, reducing the impact of rainwater on the bottom of the ring network cabinet body 1. At the same time, since the two support columns 111 move synchronously, the ring network cabinet body 1 will remain in a stable state during the up and down movement. When the ring network cabinet body 1 needs to be lowered, it is only necessary to rotate the bolt 47 to move it outward, and the guide groove 46 and the through groove 43 will be in a flow state. Through the gravity of the ring network cabinet body 1, the two support columns 111 push the hydraulic oil 411 inside the cavity 2 42 back to the inside of the storage cavity 41, so that the purpose of lowering and resetting the ring network cabinet body 1 can be achieved.
