When the rainwater descends to the drain board 4, the water retaining edge 20 can block the rainwater to the drain board 4, and then flow into the drainage channel 5, prevent that the rainwater from flowing to the house body or flowing to ground along the edge of the drain board 4, reduce the waste of water resource once more. The water guide groove 8 has a flow guide effect, rainwater falling onto the drainage plate 4 can be guided into the drainage groove 5 and flows into the water collecting groove 7 together through the drainage groove 5, and rainwater can be collected better. Especially, when the rainfall is too large, the water chute 8 can also play a role in buffering and dredging the flow direction of the rainwater. The water baffle 9 can block rainwater on the drainage board 4 which does not flow to the water chute 8 into the water chute 8, so that the rainwater is prevented from flowing away from the drainage board 4 in vain, and unnecessary waste is avoided.
With reference to fig. 2 and 3, in order to facilitate cleaning or replacement of the new water guide plate 6, slots 21 are formed in two ends of the edge of the water guide plate 4, which is far away from the top plate 3, in the vertical direction, the end portions, which are close to the ground, of the slots 21 are arranged in a closed manner, insertion blocks 22 inserted into the slots 21 on two sides are arranged at two ends of the water guide plate 6, the cross section of each slot 21 is arranged in a T shape, and the insertion blocks 22 are arranged in a matching manner with the T-shaped slots 21.
When the water guide plate 6 needs to be used, the insertion block 22 is inserted into the insertion groove 21, and the end part, close to the ground, of the insertion groove 21 is closed, so that the insertion block 22 can be prevented from falling downwards, and the water guide plate 6 is fixed on the drainage plate 4. Because rainwater flows through catchment groove 7 and can remain some impurity, will insert piece 22 this moment and break away from slot 21 to make water deflector 6 take off from drain bar 4, can clear up catchment groove 7, also can change water deflector 6, simple structure, the practicality is strong.
With reference to fig. 4 and 5, in order to better collect clean rainwater, a water filtering tank 10 and a water storage tank 11 are arranged on the ground, a collecting pipe 12 is arranged on the water filtering tank 10 and communicated with a water collecting tank 7, the end part of the collecting pipe 12 far away from the water filtering tank 10 is communicated with the lower end of the water collecting tank 7, a filtering plate 16 which stretches across and is sealed in the water filtering tank 10 is arranged in the water filtering tank 10, the filtering plate 16 divides the water filtering tank 10 into a first filtering area 101 and a second filtering area 102, the collecting pipe 12 is communicated with the first filtering area 101, a water passing pipe 13 is communicated with the second filtering area 102, a water passing hole 17 for water to pass through is formed in the filtering plate 16, and a first filtering cloth 18 is sealed on the water passing hole 17. A water passing pipe 13 is arranged between the water filtering tank 10 and the water storage tank 11, two ends of the water passing pipe 13 are respectively communicated with the water filtering tank 10 and the water storage tank 11, a second filter cloth 19 sealed in the water passing pipe 13 is arranged on the water passing pipe 13, and the diameter of the filter holes on the second filter cloth 19 is smaller than that of the filter holes on the first filter cloth 18. A water pump 14 is arranged in the water storage tank 11, and a water outlet pipe 15 penetrating out of the water storage tank 11 is arranged at the output end of the water pump 14.
When rainwater needs to be collected, the rainwater flows into the collecting pipe 12 from the water collecting tank 7 and further flows to the first filtering area 101 in the water filtering tank 10, when the rainwater flows to the water passing holes 17 on the filtering plate 16, the first filtering cloth 18 filters the rainwater for the first time, partial impurities in the rainwater are filtered, and the rainwater after the initial filtering enters the second filtering area 102. The second filter cloth 19 filters the rainwater for the second time, and since the diameter of the filter holes on the second filter cloth 19 is smaller than that of the filter holes on the first filter cloth 18, part of impurities in the rainwater are filtered again. Rainwater flows to the water storage tank 11 through the water pipe 13, and filtered rainwater is collected, so that waste of water resources is reduced. When the rainwater in the water storage tank 11 needs to be used, the water pump 14 is started, the rainwater is conveyed to a required place through the water outlet pipe 15, and water resources are reasonably utilized.
The implementation principle of the embodiment is as follows:
when the rainwater falls to the drain board 4, the water retaining edge 20 can block the rainwater to the drain board 4, and then flow into the water chute 8 or the water drainage groove 5, so as to prevent the rainwater from flowing to the house body or flowing to the ground along the edge of the drain board 4. The water chute 8 guides rainwater falling onto the water drainage plate 4 into the water drainage groove 5, the water baffle 9 can stop rainwater on the water drainage plate 4 which does not flow into the water chute 8 into the water drainage groove 8, the rainwater flows to the water guiding plate 6 together through the water drainage groove 5, and then the rainwater flows to the collecting pipe 12 quickly and smoothly along the water collecting groove 7. The rainwater flows to the first filtering area 101 in the water filtering tank 10 through the collecting pipe 12, when the rainwater flows through the water passing holes 17 on the filtering plate 16, the first filtering cloth 18 primarily filters the rainwater, part of impurities in the rainwater are filtered, and the rainwater after primary filtering enters the second filtering area 102. The second filter cloth 19 filters the rainwater for the second time, and since the diameter of the filter holes on the second filter cloth 19 is smaller than that of the filter holes on the first filter cloth 18, part of impurities in the rainwater are filtered again. Rainwater flows to the water storage tank 11 through the water pipe 13, and filtered rainwater is collected, so that waste of water resources is reduced. When the rainwater in the water storage tank 11 needs to be used, the water pump 14 is started, the rainwater is conveyed to a required place through the water outlet pipe 15, and water resources are reasonably utilized.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
