For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
The roof drainage system 100 of the embodiment of the present invention is described in detail below according to Fig. 1.
Roof drainage system 100 according to embodiments of the present invention can include outer enclosure wall 110, rain pipe 130 and draining dress
Put 150.
Wherein, the height of outer enclosure wall 110 is higher than roofing 101, and then outer enclosure wall 110 and roofing 101 can limit rainwater
Receiving space 103, rainwater receiving space 103 can be used for accommodating rainwater, and the rainwater after concentration can discharge from rain pipe 130,
Avoid rainwater is scattered from falling earthward, pedestrian is impacted.
The upper end of rain pipe 130 is connected with rainwater receiving space 103, and the lower end of rain pipe 130 is extended downwardly with by rainwater
Exported from rainwater receiving space 103.Alternatively, the upper end of rain pipe 130 can be extend into rainwater receiving space 103, rainwater
The lower end of pipe 130 extends downward into ground, and then can concentrate the rainwater in rainwater receiving space 103 and imported into ground.
Drainage arrangement 150 is arranged in rain pipe 130, when the rainwater in rainwater receiving space 103 exceedes predetermined amount, row
Water installations 150 work quickly to discharge rainwater from rainwater receiving space 103.
Rain pipe free-draining is relied solely in the prior art that is, being different from, the rain pipe of the embodiment of the present invention
130 by setting drainage arrangement 150, and then can use mechanical draining, during excessive rainfall in rainwater receiving space 103,
Quickly rainwater can be discharged from rainwater receiving space 103 by the way of mechanical draining, avoid rainwater from accumulating in room for a long time
Face 101 and producing leak to room of the top layer even below top layer influences.
Roof drainage system 100 according to embodiments of the present invention, by setting drainage arrangement 150 in rain pipe 130, make
Obtaining the drainage system has two kinds of drainage patterns, when one kind is that amount of rainfall is less in rainwater receiving space 103, can use and pass
The mode that the rain pipe 130 of system flows automatically discharges rainwater from rainwater receiving space 103, and another kind is in rainwater receiving space 103
In amount of rainfall it is more when, drainage arrangement 150 works quickly will discharge rainwater from rainwater receiving space 103, avoids rainwater
Accumulate in roofing 101 for a long time and the user below top layer or top layer is impacted.
In some embodiments of the invention, roof drainage system 100 also includes rain detecting sensor, and rainwater detection passes
Sensor is connected with drainage arrangement 150 and for detecting the amount of rainfall in rainwater receiving space 103.Detected in rain detecting sensor
When being not less than the first predetermined amount to the amount of rainfall in rainwater receiving space 103, drainage arrangement 150 works with quickly by rainwater from rain
Water receiving space 103 is discharged；It is pre- no more than second in the amount of rainfall that rain detecting sensor is detected in rainwater receiving space 103
If during amount, drainage arrangement 150 is stopped, and relies solely on the mode of the gravity flow of rain pipe 130 by rainwater from rainwater receiving space 103
Middle discharge.
Further, the first predetermined amount is not less than the second predetermined amount.That is, the first predetermined amount and the second predetermined amount
Numerical value can be with identical, or the first predetermined amount is more than the second predetermined amount.
Roof drainage system 100 can also include control centre, control centre respectively with rain detecting sensor and draining
Device 150 is connected, and control centre can receive the data that rain detecting sensor detects and according to rain detecting sensor
The working condition of the data control drainage arrangement 150 detected.For example, the keying of drainage arrangement 150 can be controlled etc..
In some embodiments of the invention, as shown in figure 1, rain detecting sensor includes starting probe 171 and stopped
Probe 173, when the rainwater in rainwater receiving space 103 is highly not less than the height for starting probe 171, the work of drainage arrangement 150
Make, and then rapidly can discharge rainwater from rainwater receiving space 103；Rainwater height in rainwater receiving space 103
During not higher than the height for stopping probe 173, drainage arrangement 150 is stopped.
Alternatively, it can be pressure sensor to start probe 171 and stop probe 173.
In some embodiments of the invention, rain detecting sensor is height detection sensor, and the first predetermined amount is corresponding
First preset height, corresponding second preset height of the second predetermined amount, rainwater receiving space 103 is detected in height detection sensor
When interior rainwater is highly not less than the first preset height, drainage arrangement 150 works, so as to which rainwater rapidly is accommodated into sky from rainwater
Between 103 discharge；Highly it is not more than the second preset height in the rainwater that height detection sensor is detected in rainwater receiving space 103
When, drainage arrangement 150 is stopped.
In some embodiments of the invention, roof drainage system 100 also includes warning device, warning device with control
The heart is connected, and exceeds in the rainwater that rain detecting sensor is detected in rainwater receiving space 103 beyond the duration of the first predetermined amount
During preset duration, control centre's control warning device sends alarm.So as to remind related personnel to enter drainage situation on roofing 101
Row maintenance, a large amount of rainwater caused by similar debris occur and blocking the upper end of drainpipe are avoided to accumulate in roofing for a long time
Phenomenon on 101.
In some embodiments of the invention, drainage arrangement 150 is water pump.It is understood that the draining dress of the present invention
Put 150 and use the specific example that water pump is the application, not the restriction of drainage arrangement 150, drainage arrangement 150 may be used also
Other equipment is thought, as long as quickly can quickly discharge the rainwater in rainwater storing apparatus.
Alternatively, roof drainage system 100 can also include filter, filter be arranged on the upstream of water pump with
Rainwater is wrapped on the impeller of water pump and influenceed so as to effectively prevent the debris such as cotton rope by being filtered before water pump to rainwater
The normal work of water pump.
Close to the position of the upper end of rain pipe 130 less than remote rainwater on roofing 101 on the roofing 101 of the embodiment of the present invention
The position of the upper end of pipe 130.And then rainwater can quickly flow to the opening of the upper end of rain pipe 130 by the gravity of itself
Place, improve the expulsion efficiency of rainwater.
