The installation structure of the conventional gate on the substation is shown in fig. 1, wherein a first gate 8 is installed on a first substation enclosure 10 through a hinge, and a second gate 9 is installed on a second substation enclosure 11 through a hinge. Normally, the first large door 8 and the second large door 9 are closed together, so that the blowing of typhoon into the substation is prevented. However, due to the fact that the wind intensity of typhoon is high, when the typhoon blows to the closed first gate 8 and the closed second gate 9, the first gate 8 and the closed second gate 9 are often damaged, and in order to prevent the first gate 8 and the closed second gate 9 on the substation from being damaged, the wind-proof blocking rod is usually installed on the first gate 8 and the closed second gate 9 in a manual carrying mode, however, the operation mode is time-consuming and labor-consuming, and the development of work is affected.
In order to solve the problem that the operation of the wind shielding device on the substation gate is time-consuming and labor-consuming, as shown in fig. 1, an embodiment of the present invention provides a manual direct-pushing wind shielding device for the substation gate, which includes a wind shielding assembly, a first transmission assembly, a second transmission assembly and a rotation assembly, wherein the first transmission assembly is disposed on the same side of a first gate 8 and a second gate 9 on the substation, and the wind shielding assembly is matched with the first transmission assembly; the second transmission assembly is arranged on a first substation enclosure 10 on the substation, the first gate 8 is connected to the first substation enclosure 10 through a hinge, and the wind shielding assembly is matched with the second transmission assembly; the rotating assembly is matched with the second transmission assembly, when the rotating assembly rotates, the rotating assembly drives the second transmission assembly to rotate, and then the wind shielding assembly on the second transmission assembly is driven to move onto the first transmission assembly, so that the wind shielding assembly abuts against the first gate 8 and the second gate 9.
Specifically, the wind shielding assembly includes a wind shielding lever 1 and a rack 101, and the rack 101 is disposed on the wind shielding lever 1 along a length direction of the wind shielding lever 1; the first transmission assembly comprises a first gear 2 arranged on the first gate 8 and a second gear 3 arranged on the second gate 9, and teeth on the first gear 2 and teeth on the second gear 3 are meshed with the rack 101; the second transmission assembly comprises a third gear 4 and a fourth gear 6 which are arranged on the first substation enclosing wall 10, wherein teeth on the third gear 4 and teeth on the fourth gear 6 are meshed with the rack 101, and the first gear 2, the second gear 3, the third gear 4 and the fourth gear 6 are all located on the same horizontal line.
