The implementation principle of the modern building roof rainwater recovery system in the embodiment of the application is as follows:

when the rainfall, the rainwater is from roof ground 1 flow direction inlet channel 2 all around, and the rainwater is by inlet channel 2 flow direction drain pipe behind the filter screen 21 that covers on the inlet channel 2 for the rainwater is filtered, finally carries to the cistern by the drain pipe, filters rubbish on filter screen 21, accomplishes the filtration and the collection of rainwater, makes rubbish move on filter screen 21 and move to the horizontal segment of filter screen 21, is favorable to retrieving the rainwater, is favorable to energy-concerving and environment-protective.

When the rain stops, the cylinder 51 is started, so that the piston 511 makes reciprocating motion to drive the scraper 4 to slide, when the piston 511 extends out of the cylinder 51, the scraper 4 slides towards the direction close to the garbage can 3, when the scraper 4 slides to abut against the compression rod 64, the scraper continues to slide, so that the compression rod 64 is pushed by the scraper 4, the compression rod 64 rotates, meanwhile, the elastic part 61 is compressed, the vibration rod 63 synchronously moves to the position abutting against the filter screen 21, so that the filter screen 21 vibrates, and meanwhile, the scraper 4 pushes the garbage on the horizontal section of the filter screen 21 into the garbage can 3, so that the garbage on the filter screen 21 is intensively collected in the garbage can 3; when piston 511 drives scraper blade 4 towards the direction motion of keeping away from garbage bin 3, compression rod 64 rotates towards scraper blade 4 under the spring action of elastic component 61, and drive vibrations pole 63 and the separation of filter screen 21, piston 511's reciprocating motion drives vibrations pole 63 repeated switching and the state of filter screen 21 butt and separation, make filter screen 21 take place vibrations, make rubbish on the filter screen 21 after the vibrations along the length direction of filter screen 21 on the horizontal segment of downward slip to filter screen 21, be favorable to cleaning the remaining rubbish on the filter screen 21, make the clearance of rubbish on the filter screen 21 more convenient, make the difficult jam of filter screen 21.

Garbage sweeps into garbage bin 3 after, the rainwater that carries in the rubbish sees through behind the hole 33 that leaks by vice bucket 32 flow direction main bucket 31, then flows into wet return 34, flow into inlet channel 2 behind check valve 35 for filtered water in the garbage bin 3 with by the filterable water of filter screen 21 converge, make by filterable rainwater by main bucket 31 to inlet channel 2 one-way flow, be favorable to improving the recovery utilization ratio of rainwater, be favorable to reducing by filterable rainwater and flow back to roof ground 11 or rubbish concentration department again.

After the rubbish clearance finishes, pull down vice bucket 32 and mention handle 36 and propose vice bucket 32 main barrel 31, pour rubbish to the refuse disposal point for the clearance of follow-up rubbish is more convenient, packs back vice bucket 32 in main barrel 31 at last, makes things convenient for clearance next time.

Through the setting of scraper blade 4 for the rubbish of concentrating on the horizontal segment of filter screen 21 can be cleaned under the promotion of scraper blade 4, makes the clearance of rubbish more convenient.

Through the setting of leaking hole 33 for rainwater in the auxiliary barrel 32 is filtered to main barrel 31 in, is favorable to reducing auxiliary barrel 32 ponding, is favorable to reducing the ponding in the auxiliary barrel 32 and soaks the condition of rubbish, is favorable to reducing rubbish and is soaked by the rainwater and lead to the smelly condition of rubbish.

Set up the setting of check valve 35 in through wet return 34 for the rainwater that is filtered in the main barrel 31 by water leakage hole 33 is discharged to in the inlet channel 2 by wet return 34, and the setting of check valve 35 is favorable to reducing the condition that the setting of wet return 34 made the rainwater in the inlet channel 2 flow back to in garbage bin 3, is favorable to reducing the rainwater and flows back to in garbage bin 3 and overflow even and take the condition of rubbish in the garbage bin 3 out.

Through linkage assembly 6 and scraper blade 4's cooperation for the motion that drives scraper blade 4 through piston 511 can drive linkage assembly 6 work in step, makes vibrations pole 63 driven vibrations filter screen 21, is favorable to reducing the needs that additionally increase synchronous power supply, is favorable to reducing the increase of extra mechanism, makes linkage assembly 6's work operation more simple and convenient, makes cleaning of rubbish more convenient.

Through the setting of brush 41, be favorable to reducing scraper blade 4 and be difficult to clean all rubbish with filter screen 21 butt completely, brush 41 flexible makes scraper blade 4 slide when cleaning rubbish more easily with filter screen 21 butt and clean rubbish for the cleaning of rubbish is more convenient.

Through the setting of ball 62, in order to reduce the slip hindrance of linkage assembly 6 to rubbish, vibrations pole 63 diameter is less, and being provided with of ball 62 does benefit to the area of contact of increase vibrations pole 63 and filter screen 21, is favorable to reducing the less vibrations pole 63 of diameter to the poor condition of filter screen 21 vibrations effect, is favorable to reducing vibrations pole 63 too thin and punctures the condition of filter screen 21, is favorable to strengthening vibrations pole 63's vibrations effect.

Through the arrangement of the elastic piece 61, before the scraper 4 abuts against the compression rod 64, the elastic piece 61 is used as a connecting piece to enable the compression rod 64 and the connecting rod 65 to form a certain angle, so that the compression rod 64 is kept at a position extending into a sliding space of the scraper 4, the compression rod 64 is enabled to abut against the scraper 4 and rotate more easily in the sliding process of the scraper 4, and the vibration rod 63 is enabled to rotate to abut against the filter screen 21 more easily under the driving of the movement of the compression rod 64; at the same time, the compression rod 64 can be automatically reset, which is beneficial to restoring the end of the compression rod 64 far away from the connecting rod 65 to the movement space extending out of the scraper 4 when the scraper 4 moves to be separated from the compression rod 64.

One end of the compression rod 64, which is far away from the connecting rod 65, is inclined and protrudes into the sliding space of the scraper 4, so that the scraper 4 is abutted against the compression rod 64 when sliding, and when the scraper 4 continues to slide, the scraper 4 pushes the compression rod 64 to rotate, so that the elastic piece 61 is deformed, the compression rod 64 is driven to rotate by the movement of the scraper 4, and the vibration rod 63 is driven to abut against the filter screen 21; the compression bar 64 is disposed obliquely so that the scraper 4 can move along the oblique guide surface of the compression bar 64 more easily during the movement, thereby pushing the compression bar 64 to rotate and compress the elastic member 61, so that the scraper 4 can push the compression bar 64 more easily, and the movement of the linkage assembly 6 is smoother.

Through the setting of filter screen 21 slope for rubbish on filter screen 21 moves to the horizontal segment of filter screen 21 under the impact of rainwater, makes rubbish concentrate on one, makes to promote scraper blade 4 and can clear up concentrated rubbish, makes the clearance of rubbish more convenient.

The sub-tub 32 is more easily lifted out of the main tub 31 by the arrangement of the handle 36.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
