Description

Technical Field

[0001] The present invention relates to the technical field of building drainage, and more particularly to a building drainage system. Background Art

[0002] At present, some houses with eaves usually have tiles piled on the top of the roof, and some of the tiles will form multiple waterways along the slope of the roof. When it rains, water will flow down along the roof. In order to prevent the water from entering the room and causing damage to the wall near the lowest end of the roof, a drainage system is usually set up to drain and recycle the water flowing down from the roof.

[0003] The patent with the publication number of CN113863588A was retrieved, which discloses a drainage system for a house building, including a house body, a roof, and a mounting wall. A gutter is arranged on the mounting wall, and the gutter includes a water outlet, a drainage trough, and an overflow channel. A drainage pipe is installed on the house body. The gutter includes a drainage seat and a mounting seat. The water outlet is opened on the drainage seat. One end of the sewage collection trough is rotatably connected to the mounting seat, and a locking member is arranged on the sewage collection trough; the drainage trough is rotatably connected to the mounting seat, and a driving source is arranged on the mounting seat. The gutter includes a scraper; a filter screen is fixedly connected to one side of the drainage trough, and a brush strip for cleaning the filter screen is arranged at one end of the scraper; the gutter includes a first mounting plate and a second mounting plate, and a limiting member is arranged on the second mounting plate; an overflow hole is arranged on one side of the drainage trough, and a water-through hole is arranged on the scraper. The gutter includes a reinforcement component, and the reinforcement component includes a filter plate. The application enables users to clean up garbage, leaves and other debris in the gutter more conveniently.

[0004] Although such a setting can more conveniently clean up garbage, leaves and other debris in the gutter, it needs to be driven by a motor when the debris in the gutter needs to be cleaned. The motor is installed in an external environment and is exposed to wind and sunlight, which will affect its service life. Moreover, it is only used when it rains, and its utilization rate is low. Therefore, the cleaning structure needs to be improved. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a building drainage system, which has the advantage of being able to collect and process impurities without using electrical facilities.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a building drainage system, comprising an eave installed on a roof, a gutter fixedly connected to the eaves, baffles fixedly connected on both sides of the gutter, a collecting trough formed between the baffle and the side wall of the gutter, two symmetrical filter plates rotatably connected to the top of the baffle, the rotation axes of the two filter plates are located on the side away from each other, a floating block is slidably connected in the gutter, the density of the floating block is less than the density of water, the floating block is slidably connected between the two baffles, grooves are provided on the tops of both sides of the baffle, the rotation axis of the filter plate is rotatably connected in the grooves, the two sides of the floating block are respectively against the two filter plates, a drain outlet is provided at the bottom of the gutter, and a drain pipe is fixedly connected to the drain outlet.

[0007] The present invention is further configured as follows: a plurality of drainage grooves are provided on the top surface of the filter plate, a receiving groove is provided on one side of the filter plate close to the groove, a plurality of through holes are provided at the bottom of the receiving groove, a plurality of the drainage grooves converge at the receiving groove, and the through holes are connected to the inside of the gutter.

[0008] The present invention is further configured as follows: support rods are fixedly connected to both sides of the floating block, a longitudinally arranged slide groove is opened on the side wall of the baffle, and the support rod is slidably connected in the slide groove.

[0009] The present invention is further configured as follows: movable grooves are provided on both side walls of the floating block, a mounting opening is provided on the side of the filter plate close to the floating block, a connecting block is rotatably connected to the mounting opening, the connecting block is slidably connected in the movable groove, the cross-section of the connecting block is T-shaped, and the connecting block fits with the inner surface of the movable groove.

[0010] The present invention is further configured as follows: a rainproof plate is fixedly connected to the top of the collecting trough, and the rainproof plate is inclined toward a side close to the filter plate.

[0011] The present invention is further configured as follows: a side of the rainproof plate close to the floating block covers the filter plate, and a water discharge portion of the rainproof plate extends to a drainage trough.

[0014] In summary, the present invention has the following beneficial effects: When it rains, rainwater can enter the eaves gutter from the filter plate for collection. After entering the eaves gutter, since the density of the floating block is smaller than that of water, the floating block can float in the water, thereby pushing the filter plate open. At this time, the impurities on the filter plate can enter the collection trough for collection along the inclination angle of the filter plate, and when it rains, when rainwater drops into the eaves gutter, it can cause the water surface to shake, causing the floating block to shake and push the filter plate. Therefore, the impurities on the filter plate are easier to enter the collection trough for collection. This drainage system does not require the use of electrical facilities, reducing the cost of electricity installation and use. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] A building drainage system, such as Figure 1-Figure 5 As shown, it includes an eave 1 installed on the roof, a gutter 2 is fixedly connected to the eave 1, baffles 4 are fixedly connected on both sides of the gutter 2, the baffles 4 are composed of two pieces, one horizontal and one vertical, respectively, symmetrically arranged in the gutter 2, and can be used together with the gutter 2 to form a collecting trough 3 for storing impurities on the roof, which is convenient for people to clean up in a centralized manner, two symmetrical filter plates 5 are rotatably connected to the top of the baffle 4, and the rotation axes of the two filter plates 5 are located on the side away from each other, and a floating block 6 is slidably connected in the gutter 2, the floating block 6 is a triangular prism, the density of the floating block 6 is less than the density of water, the floating block 6 is slidably connected between the two baffles 4, the filter plate 5 abuts against the two inclined surfaces of the floating block 6, grooves 7 are provided on the tops of both sides of the baffle 4, the rotation axes of the filter plates 5 are rotatably connected in the grooves 7, and the floating block 6 The two sides of the eaves 2 are respectively against the two filter plates 5, and a drainage port 8 is opened at the bottom of the eaves 2, and a drainage pipe 9 is fixedly connected to the drainage port 8. When it rains, rainwater can enter the eaves 2 from the filter plate 5 for collection. After the rainwater enters the eaves 2, since the density of the floating block 6 is smaller than that of water, the floating block 6 can float in the water, thereby pushing the filter plate 5 open. At this time, the impurities on the filter plate 5 can enter the collecting trough 3 along the inclination angle of the filter plate 5 for collection, and during the rainy process, when rainwater drips into the eaves 2, it can cause the water surface to shake, thereby causing the floating block 6 to shake and push the filter plate 5. Therefore, the impurities on the filter plate 5 are easier to enter the collecting trough 3 for collection. This drainage system does not require the use of electrical facilities, reducing the cost of electrical installation and use.

[0021] In one embodiment, support rods 12 are fixedly connected to both sides of the floating block 6, and a longitudinally arranged slide groove 13 is opened on the side wall of the baffle 4. The support rod 12 is slidably connected in the slide groove 13. The two sides of the floating block 6 in the length direction are in contact with the side walls of the eaves gutter 2, and the other two sides can be supported by the support rods 12, thereby ensuring that the floating block 6 can rise stably at the center of the eaves gutter 2 to prevent the floating block 6 from shifting. Movable grooves 14 are provided on both side walls of the floating block 6, and an installation opening 15 is provided on the side of the filter plate 5 close to the floating block 6. A connecting block 16 is rotatably connected to the installation opening 15, and the connecting block 16 is slidably connected to the movable groove 14. The cross-section of the connecting block 16 is T-shaped, and the connecting block 16 fits the inner surface of the movable groove 14. Therefore, the cross-section inside the movable groove 14 is consistent with the connecting block 16, so that the connecting block 16 can be stably stuck in the movable groove 14 and slide. When the rainfall is large, the up and down movement frequency of the floating block 6 will also increase. The T-shaped connecting block 16 can be stably stuck on the surface of the floating block 6 to prevent the floating block 6 from separating from the filter plate 5, thereby preventing impurities from entering the eaves gutter 2, which is convenient for cleaning impurities.

[0022] Furthermore, a plurality of drainage grooves 10 are provided on the top surface of the filter plate 5, a receiving groove 22 is provided on one side of the filter plate 5 close to the groove 7, a plurality of through holes 11 are provided at the bottom of the receiving groove 22, and the plurality of drainage grooves 10 converge at the receiving groove 22, and the through holes 11 are connected to the inside of the gutter 2. When it rains, rainwater can flow along the drainage grooves 10, preventing rainwater from flowing arbitrarily on the surface of the filter plate 5, so that rainwater can enter the receiving groove 22 along the drainage grooves 10, and enter the gutter 2 from the through holes 11, which is convenient for collecting rainwater. A rainproof plate 17 is fixedly connected to the top of the collecting tank 3, and the rainproof plate 17 is inclined toward the side close to the filter plate 5, and the side of the rainproof plate 17 close to the floating block 6 covers the top of the filter plate 5, and the drainage part of the rainproof plate 17 extends to the drainage groove At 10, the rainproof plate 17 can block rainwater during rainfall to prevent rainwater from directly pouring into the collecting trough 3. A collecting net 18 is detachably connected to the collecting trough 3. A through groove 19 is provided at the bottom of the collecting trough 3. A collecting bucket 20 is fixedly connected to the bottom of the collecting trough 3. The bottom of the collecting bucket 20 is mutually conductive with the inside of the eaves gutter 2. The side of the collecting net 18 is made of rust-proof metal with anti-deformation effect. The bottom of the collecting net 18 is a mesh structure, which can intercept impurities and drainage. The bottom and side of the collecting net 18 are connected by glue or clips and can be disassembled. When the collecting net 18 needs to be replaced, the bottom of the collecting net 18 can be disassembled to prevent impurities from sticking to the bottom of the collecting net 18 and making it inconvenient to clean, thereby improving the service life of the collecting net 18.

[0023] Furthermore, the thickness of the side wall of the gutter 2 close to the eaves 1 is greater than that of the side away from the eaves 1, and a water collecting groove 21 is opened on the top surface of the side wall with the greater thickness of the gutter 2. The thickness of the gutter 2 close to the eaves 1 is greater, which facilitates the opening of the water collecting groove 21 on the side wall of the gutter 2, prevents the part where the water collecting groove 21 is opened from being weak and affecting the service life of the gutter 2, and ensures that the gutter 2 and the eaves 1 can be stably connected.

[0024] The use process of the present invention is as follows: When it rains, rainwater flows along the filter plate 5 into the eaves gutter 2 for collection. After a period of time, more rainwater can be collected in the eaves gutter 2, causing the floating blocks 6 to float in the water, thereby pushing open the filter plates 5 on both sides. At this time, the impurities on the filter plate 5 can flow along the inclination angle of the filter plate 5 and enter the collecting trough 3 for collection. No electricity resources are required in this process. The rainwater on the surface of the filter plate 5 can flow along the drainage trough 10 and enter the eaves gutter 2 from the through hole 11 for collection, preventing rainwater from entering the collecting trough 3 and making the impurities damp and smelly, thereby improving the management effect of the environment around the eaves 1.

[0025] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
