Description

push-up drain

This creation belongs to the field of building materials, especially about a push-up drainage device, which uses water to drive a spiral blade, so that the filter cover on the top of a body can be reciprocated and lifted, so as to push away the accumulated foreign matter and drain water smoothly. Those who can improve the water drainage and avoid being unable to drain due to the accumulation of foreign matter.

According to, in order to prevent floods and avoid floods, drainage systems of various sizes are distributed throughout the city, which can effectively collect rainwater into the rainwater sewer and discharge it downstream into the sea; Small drainage pipes, and in order to prevent foreign matter from entering and blocking the drainage pipes, a filter screen or a water drop head is installed at the entrance of the drainage pipe road (also known as a drain hole), which naturally affects the drainage time more easily. Generally speaking, if there is a sudden heavy rainfall, it will produce stagnant water.

The filter screens or drain heads currently appearing on the market are all covered on the surface of the drain hole, or placed in the drain hole, and most of them will form the part required for filtration on the surface of the drain hole, which will naturally make the drain hole The area is reduced. When the rainfall is slightly heavy, the drainage is not enough to form water accumulation. After the rainfall slows down, it will be discharged slowly through the filter screen or the water discharge head. Effective drainage; moreover, especially during typhoons, because leaves or sundries are often blown off, driven by the water flow, they will also accumulate around the drainage holes. But it will affect the smoothness of drainage, or even no drainage.

For example, the Republic of China Invention Patent No. I255306 "Flood Control Method for Metropolitan Areas and Its Automatically Adjusting Water Outlet Head" discloses the use of a water outflow head that can automatically adjust the water outflow. The rainfall is stored, and the water outlet speed is controlled by slowing down the water head, so that a part of the rain will stay in the high place and not gather in the drainage ditch at the bottom of the building, effectively avoiding the flooding of the roadway; the water head structure is mainly equipped with a base and At least one intermediate seat is provided with a horizontal plate at the bottom of the base, which can be fixed to the ground by nails, and the plate of the base is provided with a water outlet gap, and at least one liftable intermediate seat system passes through the interior of the base , and make the top of the middle seat through which it passes is transparent, at least one middle seat body is provided with a water outlet gap, the bottom end is provided with a horizontal plate, and a buoy is connected to the top of the middle seat body, which is connected by The rise of the water level after the accumulation of water drives the height of the middle seat to adjust the water output of the drainage hole. Although the effect of adjusting the drainage can be achieved, the problem of water accumulation caused by the accumulation of foreign objects has not been eliminated, so it is necessary to improve.

In view of this, the creator specially designed a push-up drainage device. When it rains heavily, it will use the water flow to drive a spiral blade, so that the filter cover on the top of the body can be reciprocated, and the drainage area can be increased. Increase the drainage, and use the reciprocating lifting of the filter cover to open it so that the foreign matter accumulated near the drain hole can be drained smoothly, and it can avoid the problem that the drain hole cannot be drained due to the accumulation of foreign matter, and solve the aforementioned various filters or Falling head overboard with existing problematics.
