Problems solved by technology
Especially in substations, many substations have the phenomenon of "flooded substations" due to poor drainage during heavy rain seasons, causing casualties and economic losses. A lot of debris, when the rainfall is too heavy, the debris will be washed to the vicinity of the manhole cover to block the area around the manhole cover, and the rainwater will gather on the road in the substation, causing the substation to be flooded

specific Embodiment approach
[0053]Specific embodiments: when people use the drainage equipment designed by the present invention, during normal use, if there is water accumulation around the well cover 2 in a rainy day, the water around the well cover 2 will pass through the first side of the well cover 2 Shaped water inlet 19 flows into the filter disc 13; then flows into the hemispherical water filter structure 5 and the annular water filter structure 6 through the filter water hole 21 on the filter disc 13; The manhole cover 2 on the upper side of the water filter structure 6 and the first square water outlet 19 and the filter water hole 21 on the filter disc 13 are not blocked; The amount of water on the water structure 5 is large; that is, the gravity of the water on the annular water filtering structure 6 is greater than the gravity of the water on the hemispherical water filtering structure 5; that is, the annular water filtering structure 6 will move downward at this time; the annular water filter...

The invention belongs to the technical field of drainage equipment, and particularly relates to underground drainage equipment based on a lever principle used in substations. The underground drainageequipment includes a well cover mounting shell, a well cover, a hemispherical water filter structure and an annular water filter structure, and in the course of use, if sundries such as branches and leaves exist near the well cover, if the equipment is used for a long time, the branches and leaves clog the periphery of the well cover; if rainy days are encountered or when the water accumulates around the well cover, the amount of water flowing into the annular filter structure is less than that flowing into the hemispherical filter structure; at this time, the hemispherical filter structure moves downwards so as to enable the well cover to move upwards; the well cover move upwards to enable the sundries such as branches and leaves on the upper side of the well cover to move together to theupper side; and meanwhile, a clamping rod on a filter circular plate moves out of the upper end of the well cover so as to clamp tightly the sundries such as branches and leaves on the upper side ofthe well cover and prevent the situation that water drainage is affected due to the fact that sundries such as branches and leaves slide down to the lower side of the well cover to block the lower side of the well cover.
Description
[0001] Technical field [0002] The invention belongs to the technical field of drainage equipment, and in particular relates to an underground drainage equipment used in a substation based on the principle of leverage. Background technique [0003] At present, due to the rapid development of urban expansion and urbanization, there are certain defects in the drainage system of large and medium-sized cities in my country. Especially in substations, many substations have the phenomenon of "flooded substations" due to poor drainage during heavy rain seasons, causing casualties and economic losses. A lot of debris, when the rainfall is too heavy, the debris will be washed to the vicinity of the manhole cover to block the surroundings of the manhole cover, and the rainwater will gather on the road in the substation, causing the substation to be flooded. Therefore, it is very necessary to design a kind of launching equipment that can automatically eliminate the impact of debris on ...
