A buffering area is set between precipitation filtering area and the drainpipe, filter is provided with the buffering area.
The filter sizes of the filter are the 4 of the draining pipe diameter~5 times.
The filter is filter membrane, and the filter membrane both sides are provided with fixture.
The fixture is the steel wire for being arranged at the filter membrane both sides.
The filter is arranged in the neck of mounting seat, and the mounting seat is fixed on institute using rubber seal rings for seal
State on cavity.
Lifting piece is provided with the mounting seat.
The beneficial effect that the utility model reaches：
1st, it is provided with partition wall in cavity, slows down while energy dissipating, beneficial to sludge settling, due to reducing the current stream of water inlet
Speed, the disturbance of bottom rainwater being reduced, the pollutant or particle for facilitating larger volume and quality are precipitated, in order to avoid block filtering
Device；Filter uses larger filter area, is four to five times of drainpipe area, and filter efficiency is high, and speed is fast.
2nd, the bottom of cavity is provided with the flow channels to Caused by Sloping Surfaces, makes sludge be easy to settle, and quickly and easily discharge is dirty
Thing or particulate matter are contaminated, precipitates and one section of buffering area is set between filtering area and drainpipe, not only acts as and is connected with drainpipe stabilization, by
Gradually tapered up in caliber, flow velocity is particularly advantageous for the rainwater after filtering and quickly collected by increasing.
3rd, filter membrane is relatively low compared to the traditional filtering structure by compositions such as gravel, sand, good filtration effect, light weight, cost；
Filter membrane is fixed using neck and steel wire auxiliary is fixed, and filtration reliability is good.
4th, the device is applied to different rainfall intensities, no matter rainfall size, the device can all be run, without the machine of complexity
Tool structure and electronic-controlled installation, operational reliability are higher.
5th, filter is provided with the pulling apparatus for being conveniently replaceable filter membrane, is convenient for the maintenance of filter, meets regular
Maintenance and inspection demand, long lifespan.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of rainwater precipitation filter, installed in ground below 1, and is provided with well lid 2, including chamber
Body 14, the cavity 14 are provided at both ends with water inlet pipe 3 and drainpipe 13, partition wall 5, the partition wall are provided with the cavity 14
The cavity 14 is separated into inhalant region 4 and precipitation filtering area 7 by 5, and space is left at the top of the partition wall 5 and the cavity 14,
The lower section of the partition wall 5 is provided with flow channels 15, and the flow channels 15 are provided with downward domatic, and the present embodiment is triangular prism
Body, the side of the flow channels 15 are provided with discharge pipeline 6, and gate valve, the precipitation filtering area 7 are provided with the discharge pipeline 6
One buffering area 12 is set between the drainpipe 13, and the present embodiment buffering area 12 is half horn-type structure, the buffering area 12
Filter 8 is inside provided with, the filter 8 is arranged in the neck 10 of mounting seat 9, is provided with and is carried in the mounting seat 9
Draw piece, the present embodiment lifting piece are lifting ring, can also be lifting rope, and the mounting seat 9 is fixed using rubber seal rings for seal
In on the cavity 14, the filter sizes of the filter 8 are 4~5 times of the diameter of drainpipe 13, described in the present embodiment
Filter 8 is filter membrane, and the filter membrane both sides are provided with fixture 11, and the present embodiment fixture 11 is to be arranged at the filter membrane two
The steel wire of side.
The course of work：When raining, rainwater enters inhalant region by collecting from water inlet pipe, when flow rate of water flow is larger, can hit
Energy dissipating partition wall is hit, slows down flow rate of water flow.When low speed water passes through the flow channels under baffle plate, the pollution of larger volume and quality
Thing or particulate matter can precipitate under gravity and effect of inertia, and the flow channels of slope are easy to the deposition of sludge.When water is continuous
Increase, water level is concordant with filter membrane or during the above, current can be filtered by filter membrane, the impurity in further removal current, and
Into exhalant region, the exhalant region of ramp type facilitates collecting for current.Last rainwater is discharged by drainpipe.At the end of rainfall, beat
The gate valve for driving discharge pipeline carries out spoil disposal, and surplus water can take away sludge in device, will not form sludge alluvial in bottom of pond.Work as filter
When film reaches service life, the replacing of filter assemblies, without entering in well, side by proposing mounting seat, can be carried out outside device
Just it is quick.
It should be appreciated that embodiment and example discussed herein simply to illustrate that, to those skilled in the art
For, it can be improved or be converted, and all these modifications and variations should all belong to the appended claims for the utility model
