Background
With the rapid development of economy in China, the development concept of green and health is more and more deep into the mind, and the problem of environmental pollution caused by the increasingly accelerated urbanization process is more and more emphasized by environmental workers. The rainwater inlet which is visible everywhere in a city is an inlet for collecting rainwater runoff by urban drainage pipelines and is also a source and a passage port for a large amount of pollutants in the rainwater runoff to enter a pipe network. Therefore, the method is of great importance in arranging a purification and sewage interception measure at the rainwater port, can reduce the downstream discharge of rainwater runoff pollutants and control the non-point source pollution of urban water, and has great significance in improving the urban environment.
The rain water inlet is a starting structure for collecting rain water in a ground rain water drainage system and comprises a water inlet grate, a well body, a water outlet pipe and the like. Rainwater on the road surface converges and enters the rainwater pipeline system through the collection of the rainwater port. The rainwater drainage system is not only connected with rainwater runoff collected by the urban drainage system, but also introduces urban pollutants, and indirectly influences urban traffic, urban water environment, environmental sanitation and human health.
The rainwater runoff carries large-particle garbage, such as plastics, branches, silt and the like, so that organic matters, heavy metals, nutrient salts, grease and the like in the road surface and the roof are washed and dissolved, and pollutants enter a rainwater inlet along with water flow and are discharged into a river channel through a pipeline, so that the water environment is seriously threatened; on the other hand, organic matters in the drainage pipeline can generate gas with strong odor under the anaerobic condition, such as hydrogen sulfide, methane, ammonia, mercaptan and the like, and the gas escapes from the gutter inlet, so that the comfort of residents and pedestrians is seriously affected.
At present, the traditional gutter inlet which is generally adopted in China is usually designed based on whether the drainage capacity of the traditional gutter inlet can meet the rainfall requirements of heavy rain and extra heavy rain, and most of the traditional gutter inlets are single in type and lack of purification function. These traditional inlet for stoms have the easy problem that causes the jam, silt separation effect is not good, foul smell leaks etc. consequently, it is also very necessary to carry out the research to the inlet for stom s that reaches better pollutant interception effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take dirty type inlet for stom water of cutting of filter screen, solve traditional inlet for stom water and only can collect the road surface rainwater and can't cut dirty, the foul smell problem of leaking.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides a take dirty type inlet for stom water of cutting of filter screen, includes spring, separation blade and filter screen, and spring, separation blade and filter screen connect gradually, and the other end of spring and the other end of filter screen are connected with the both sides of inlet for stom water well room respectively. The initial rainwater flows into the filter screen firstly and then flows into a rainwater pipeline after being filtered; along with the water yield increases, the filter screen filter capacity is not enough, because the effect of separation blade, the water storage capacity in the filter screen increases, makes the spring extension, holds full water back in the filter screen, and the rainwater will directly flow into rainwater pipeline through the overflow.
Further, still include the baffle, the baffle sets up the top at the spring.
The utility model has the advantages that: the sewage interception type gutter inlet with the filter screen has the advantages of good sewage interception effect, simple structure, simple and easy construction, less engineering investment, no need of extra occupied land and the like; the initial rainwater with high pollutant content in the initial stage of rainfall can be collected in time, urban non-point source pollution is reduced, the elongation of the spring is increased due to the impact of the water on the filter screen along with the increase of the amount of the water, the amount of the overflowing rainwater is increased, and the influence on the normal water drainage capacity of the rainwater inlet is small; in addition, the device can intercept larger pollutants and partial smaller solid pollutants such as sand grains, dust and the like, and when sundries are cleaned in the later period, the sundries can be conveniently cleaned by opening the grate and lifting the filter screen, so that the sundries cleaning cost and the labor intensity are reduced.
Further, still include the baffle, the baffle sets up the top at the spring. When the road surface rainwater is not born in dry seasons, the baffle plate and the filter screen form a relatively closed device to prevent the possible odor of the rainwater inlet from overflowing.

The utility model discloses a theory of operation:
when rainfall does not occur, as shown in fig. 1, the baffle plate and the filter screen form a relatively closed device to prevent odor possibly existing in the rainwater inlet from overflowing. When rainfall happens, rainwater flows into the rainwater port through the road surface gradient, the initial rainwater flow rate is small, and more pollutants are contained. Rainwater firstly enters the filter screen, the filter screen is made of geotextile with a supporting structure, and initial rainwater with solid particle pollutants or suspended pollutants enters the rainwater inlet and is intercepted and filtered in the hanging basket.
As shown in figure 2, along with the duration of the rainfall process, a large amount of rainwater begins to enter the rainwater port through the rainwater grate, the filter screen is not filtered timely, due to the effect of the separation blade, the rainwater in the filter screen continuously increases, the spring begins to extend, and the rainwater in the filter screen begins to overflow after being fully stored. Along with the rainfall increase, the rainwater leads to the spring flexible volume to reach the biggest to the impact of filter screen, and the rainwater flows into the well indoor through the overflow fast and is discharged away through rainwater pipeline.
After precipitation is finished, rainwater is not carried in the filter screen, the rainwater in the filter screen flows into the well chamber after being filtered, and the extension spring slowly contracts until the length of the extension spring is close to the length of the rainwater.
To sum up, the utility model discloses a take dirty type inlet for stom water of cutting of filter screen not only cuts dirty, can also deodorant. The utility model is provided with a baffle plate, a spring, a catch and a filter screen structure in the well chamber of the traditional gutter inlet, so that the initial rainwater can flow into the filter screen first and then can enter the rainwater pipe network system after being filtered; along with the increase of the water quantity, the filter screen cannot filter timely, after the liquid level in the filter screen exceeds the limit, the rain water crosses over the early stage of rainfall, and the rain water directly overflows into the rainwater port and is directly drained away. In the continuous rainfall process, a large amount of rainwater enters the rainwater inlet to impact the filter screen, the spring extends to the limit value, and the rainwater quickly overflows to the rainwater inlet. After the rainfall is finished, all the rainwater in the filter screen is discharged into a rainwater port, the spring is restored to be close to the length before the rainfall, and the next rainfall cycle is waited.
