Description

A new centrifugal type anti-clogging rainwater outlet

technical field

The utility model relates to the technical field of drainage, in particular to a novel centrifugal type anti-clogging rainwater outlet.

Background technique

In recent years, due to various factors such as climate change and urban construction, urban waterlogging has occurred frequently, which seriously threatens the safety of residents' lives and properties. In addition to the increase in extreme rainstorms, the phenomenon of urban flooding is also particularly common due to the reduction of water discharge capacity due to blockage of storm drains and siltation of storm water pipes. The storm drain is the main auxiliary structure of the urban drainage pipeline system and an important part of the urban road drainage. Storm drains are located at the beginning of the urban drainage system, usually at a certain distance from municipal roads, squares, street intersections and street ditches. The gully is the starting point of the urban drainage system, which has the function of collecting rainwater and intercepting dirt. The scientific and reasonable design of the sewage interception gullies can reduce the phenomenon that sediment and other garbage block the gullies and cause the rainwater to fail the roads or cause water accumulation in the roads and low-lying areas to form water spots, which hinder traffic or damage the roads. The structural design of road drainage pollution control facilities is particularly important. Therefore, while the waterlogging control is reasonably designed, updated, managed and maintained, and LID and GSI measures are adopted, attention should be paid to the design of urban road stormwater outlets in the design of drainage pipe network. Reasonable renovation of the drain.

At present, most of the rainwater inlet structures laid on the road are the rainwater well grate on the top surface, the rainwater inlet wellbore below, the rainwater branch pipe at the bottom to connect the rainwater well, and the rainwater well grate has many holes. When cleaning, it is easy to bring fallen leaves and sand into the rainwater well, and the sediment carried by the initial rainwater is also easy to deposit at the bottom of the rainwater well, causing the sewer channel to be blocked and waterlogging spots formed during the rainy season. In order to reduce the blockage and improve the drainage performance, it is necessary to open the rainwater grate regularly to clean up the internal garbage, which is time-consuming, laborious, and dangerous. The cleaning of storm water gully on the road also greatly affects the smoothness of urban road transportation and traffic safety. The leaves and other garbage deposited in the rainwater outlet will ferment and rot in the rainwater and emit peculiar smell, pollute the surrounding air, and may also cause major economic losses and adverse social impacts such as pipeline explosion.

Therefore, a new type of rainwater inlet design is urgently needed to solve the problem that the rainwater outlet is easily blocked and inconvenient to clean.

Embodiment 1, please refer to Figure 1, a new centrifugal type anti-clogging rainwater inlet, including a rainwater inlet body 1, a rainwater inlet well grate 2, a baffle 3, a sling 4, a collection pipe 5, a spiral curved surface 6, and a mud collecting tank 7. Hook 8, rainwater pipe 9, overflow hole 10, overflow hole 11.

FIG. 2 is a top view of the spiral separation device, and FIG. 3 is a three-dimensional view of the spiral separation device, including a spiral curved surface 6 , a collecting pipe 5 and a baffle 3 . During the rainy season, rainwater falls on the spiral surface 6, and a swirling flow is formed under the action of the baffle 3 that prevents rainwater from splashing. The collected silt is introduced into the silt collecting tank 7 at the bottom through the middle collecting pipeline 5, so as to realize the effect of sediment separation.

When the rainwater manhole cover is submerged by the accumulated water, the air pressure in the well can reach more than 1.1atm, which is not conducive to the discharge of water. When the rainwater falls through the spiral separation device, it will drive the internal air to circulate and flow. The vortex forms a hollow air hole in the middle, which makes the air pressure inside and outside the gully balance, and the water discharge capacity can be increased by about 1.3 times, reducing the occurrence of local water accumulation.

Figure 4 is a sectional view of the mud collecting tank, including the mud collecting tank 7, the hook 8, the overflow large hole 10, and the overflow small hole 11. During the rainy season, the rainwater separated by the spiral separation device flows into the mud collecting tank 7. When the water collection volume of the rainwater well is small, the water overflows from the overflow hole 11 and enters the rainwater pipe. The sediment washed in during the rainy season is trapped in the mud collecting tank 7, and is periodically removed and cleaned manually. When the water collection volume of the rainwater well is so large that the filtration speed cannot meet the drainage requirement, the water overflows from the overflow large hole 10 of the mud collecting tank 7 .
