Description

Technical Field

[0001] The utility model relates to the technical field of rainwater treatment systems, in particular to an energy-saving building rainwater treatment system. Background Art

[0002] The energy-saving building rainwater treatment system is a device that uses rainwater resources to collect, filter and store it. The treated rainwater is then used for non-drinking purposes such as irrigation, flushing toilets, and laundry, thereby reducing the demand for groundwater and tap water and achieving the goal of energy conservation and environmental protection.

[0003] There are many ways to collect rainwater in the existing energy-saving building rainwater treatment systems. Collecting rainwater on the roof is one of the ways. By setting a water receiving trough under the eaves, the rainwater flowing down the eaves flows into the rainwater treatment device through the diversion pipe for treatment and storage. However, when the rainwater in the water receiving trough flows into the diversion pipe, since dead branches and rotten leaves will accumulate on the roof for a long time, when it rains, the rainwater will bring them into the water receiving trough and flow into the diversion pipe through the water receiving trough. The long-term accumulation will cause blockage in the diversion pipe, which is inconvenient to clean. In order to reduce the blockage of the diversion pipe caused by dead branches and rotten leaves inside the diversion pipe, an energy-saving building rainwater treatment system with improved structure is proposed.

[0006] A rainwater treatment system for an energy-saving building comprises a water receiving trough arranged under an eave, wherein the height of one end of the water receiving trough is lower than the height of the other end, a collecting trough is arranged below the end of the water receiving trough with a lower height, a sewage outlet is arranged at the bottom of the inner wall of the collecting trough close to the side of the water receiving trough, a sealing cover plate matched with the size of the sewage outlet is arranged at a position corresponding to the sewage outlet, a side of the lower surface of the sealing cover plate away from the water receiving trough is movably hinged to the bottom of the collecting trough, a push rod is arranged between the lower surface of the sealing cover plate and the bottom of the collecting trough, two ends of the push rod are movably hinged to the sealing cover plate and the collecting trough respectively, a grating plate with a bottom inclined toward the side close to the water receiving trough is transversely arranged at the side of the bottom of the inner wall of the collecting trough close to the sewage outlet, a branch pipe penetrating the collecting trough is arranged at the side of the bottom of the inner wall of the collecting trough away from the sealing cover plate, the water outlet end of the branch pipe is connected to the main pipe, and the main pipe is connected to a rainwater treatment device.

[0007] Preferably, an L-shaped baffle is provided on the side of the water receiving trough away from the eaves.

[0008] Preferably, a partition plate located inside the collecting tank is vertically arranged above the grid plate.

[0009] Preferably, a dust cover is provided on the top of the collecting tank and above the partition plate.

[0010] Preferably, a sealing ring is provided at the edge of the sealing cover plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a collecting trough, a sealing cover plate and a grating plate, rainwater flows into the collecting trough through the water receiving trough into a side of the inner wall close to the water receiving trough, and the rainwater is filtered through the grating plate and flows into a branch pipe arranged on the side of the grating plate away from the sealing cover plate, so that the sewage flowing into the branch pipe is filtered in advance, and the flow of dead branches and rotten leaves into the branch pipe is reduced without causing blockage. The intercepted dead branches and rotten leaves will accumulate on the upper surface of the sealing cover plate, and when cleaning, the sealing cover plate will be flipped open by contracting the push rod to discharge the dead branches and rotten leaves accumulated on the upper surface of the sealing cover plate, so that the dead branches and rotten leaves accumulated on the upper surface of the sealing cover plate can be discharged, which is convenient for cleaning. It is relatively convenient and solves the problem that the dead branches and rotten leaves accumulated on the roof of the existing energy-saving building rainwater treatment system will cause blockage inside the guide pipe when collecting rainwater on the roof.
