Description

Technical Field

[0001] The utility model relates to the technical field of rainwater recycling, in particular to a rainwater collection and filtering system for a building facade. Background Art

[0002] Building facades are divided into building exterior facades and building interior facades. Generally, building exterior facades include all the external protective parts of the building except the roof. In certain specific cases, such as when the roof and wall of a building with a specific geometric shape show strong continuity and are difficult to distinguish, or when the roof is treated as the "fifth facade" of the building for the needs of a specific building observation angle, the roof can also be regarded as a component of the building exterior facade. In actual situations, due to the large area of ​​the building exterior facade, the amount of rain falling on the vertical wall is not less than the amount falling on the top flat layer. Therefore, collecting rainwater on the building exterior facade can not only obtain more rainwater collection, but also prevent rainwater from seeping down the wall and soaking and damaging the wall coating.

[0003] In the prior art, rainwater is collected by installing open pipes on the facade. However, due to the poor fit between the pipes and the wall, the water blocking effect is poor, and some rainwater still seeps downward along the facade. In addition, when the existing pipes collect rainwater, it is difficult to collect the rainwater because the pipes are horizontally paved. Especially when the rainfall is small, the rainwater cannot be effectively collected and converged downward. For this reason, we propose a rainwater collection and filtration system for the building facade. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a rainwater collection and filtration system for the facade of a building. The system has a reliable rainwater collection unit, which can improve the collection effect of rainwater. No matter how much rainwater there is, it can be effectively collected and converged downwards. The inner lining rubber strip can improve the rainwater collection effect while preventing rainwater from seeping downwards along the facade of the building. The system also has a reliable filtering and storage unit, which can filter the collected rainwater multiple times. A buffer component is provided at the lower end of the sewer pipe, so that rainwater can be left to settle while flowing through it, and the detachable end cover can be easily removed to clean up the deposited silt and other debris, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rainwater collection and filtration system for a building facade, located on the building, comprises a rainwater collection unit and a filtration and storage unit;

[0007] Rainwater collection unit: comprising a water collection trough, a sewer pipe, a support block, an inner paving inclined plate and a diversion inclined frame. The facade of the building body is equidistantly provided with multiple layers of water collection troughs, each layer of the water collection trough is composed of four sections and surrounds the outside of the building body. A support block is fixedly connected to the inside of the water collection trough and at the left side of each section of the water collection trough. An inclined end face is provided on the upper right side of the support block. An inner paving inclined plate is fixedly installed inside each section of the water collection trough. The four inner paving inclined plates are connected end to end, and the lower end corresponds to the high end of the adjacent inner paving inclined plate. The inclined end of the support block supports and is fixedly connected to the lower side of the higher end of the inner paving inclined plate. A diversion inclined frame is installed on the top of the building body, and the four sides of the diversion inclined frame are inclined end faces. A vertical sewer pipe is installed at each of the four side ridges of the building body. The sewer pipe passes through the corner of the water collection trough, and a through hole connected to the inside of the water collection trough is opened at each layer of connection.

[0008] Filter storage unit: installed on the lower side of the building; includes a water storage tank, which is connected to the sewer pipe through a filter.

[0009] The diversion inclined frame on the top can effectively guide the rainwater falling on the roof to the topmost water collection channel. The water collection channels on other layers can collect rainwater falling on the facade of the building at the same time. The rainwater flowing into the water collection channel is collected at the corner along the inner inclined plate and flows downward along the sewer pipe. The support block is used to lift one end of the inner inclined plate so that the inner inclined plate can be installed obliquely inside the water collection channel to speed up the collection of rainwater, so that it can be quickly collected even when the surplus is small. The filtering and storage unit can filter and store the flowing rainwater.

[0010] Furthermore, the rainwater collection unit further comprises a first fixing bolt and sealing glue, and two left and right mounting holes are opened on the inner wall of the water collection channel close to the wall, the ports of the mounting holes are filled with sealing glue, and the first fixing bolt is installed inside the mounting hole, and the water collection channel is fixed to the outside of the building through the first fixing bolt. The first fixing bolt is used to fix the water collection channel to the wall, and the sealing glue is used to block the mounting hole, thereby preventing the first fixing bolt from rusting due to long-term immersion in water.

[0011] Furthermore, the rainwater collection unit further comprises an inner lining rubber strip, which is padded between the water collection channel and the building's outer facade, and is clamped and fixed between the water collection channel and the building's outer facade, with the upper end of the inner lining rubber strip protruding a little, and the edge of the upper protruding end is chamfered. After being squeezed by the water collection channel, the inner lining rubber strip can fit tightly between the water collection channel and the building's outer facade, effectively reducing the existence of gaps, and with the chamfered structure at the upper edge of the inner lining rubber strip, rainwater falling on the outer facade can be effectively diverted to the water collection channel.

[0012] Furthermore, the filtering and storing unit includes a connecting transverse pipe, a filter, a water storage tank and a filter screen. A water storage tank is installed at both the front and rear end surfaces of the lower side of the building body. The water storage tank is connected to the sewer pipes on the left and right sides through the connecting transverse pipe, and a filter is embedded and installed in the middle section of the connecting transverse pipe. The uppermost end of the sewer pipe and the through hole connected to each layer of the water collection channel are installed with a filter screen. The filter screen is used to play a preliminary filtering effect on rainwater to filter out larger debris such as dead leaves. The connecting transverse pipe is used for the communication between the lower section of the water collection channel and the water storage tank. The filter is used to play a further filtering effect on rainwater when it flows into the water storage tank.

[0013] Furthermore, the filter storage unit further comprises a removable end cap and a second fixing bolt. The lower end of the sewer pipe is provided with a removable end cap, which is sleeved on the lower end of the sewer pipe from the lower side and fixedly connected to the lower end of the sewer pipe by the second fixing bolt. The second fixing bolt is used to fix the removable end cap. When rainwater flows through the lowermost section of the sewer pipe, it is buffered at the removable end cap and is statically settled there. By removing the second fixing bolt, the removable end cap can be removed to clean the deposited sludge and other debris.

[0014] Furthermore, the filtering and storing unit further comprises a drain pipe and a rotary valve. A rotary valve is installed at the middle position of the lower front end of the water storage tank. The front end of the rotary valve is fixedly connected with a drain pipe, and the drain pipe is connected to the inside of the water storage tank through the rotary valve.
