[0021] Embodiment one

[0022] As Figure 1 and Figure 2 The roof rainwater collection and utilization system shown in the drawings, including building 100 and foundation pit 101,

[0023] The rainwater filtering box 102 and the rainwater precipitation box 108 are arranged in a stepped manner in the foundation pit 101,

[0024] An open limiting slot 103 is arranged on the upper end surface of the rainwater filtering box 102,

[0025] A hollow baffle 105 is arranged on the upper inner wall of the rainwater filtering box 102 and below the open limiting slot 103,

[0026] A primary filter plate 104 is arranged in the open limiting slot 103,

[0027] A secondary filter plate 106 is arranged on the surface of the hollow baffle 105,

[0028] An overflow pipe 107 connected with the rainwater precipitation box 108 is arranged on the upper outer wall of the rainwater filtering box 102,

[0029] A water pump 110 and a water storage tank 113 are arranged on one side of the foundation pit 101,

[0030] A water pump water conveying pipe 111 connected with the water pump 110 is arranged on the rainwater precipitation box 108,

[0031] A water storage water conveying pipe 112 connected with the water pump 110 is arranged on the water storage tank 113,

[0032] A high-pressure drainage pump 114 is arranged on one side of the water storage tank 113,

[0033] A drainage pipe 115 connected with the high-pressure drainage pump 114 is arranged on the water storage tank 113,

[0034] A water outlet pipe 116 is arranged on the high-pressure drainage pump 114.

[0035] The working principle is as follows: first, the roof rainwater is filtered (separated from sundries such as leaves mixed in the rainwater) by the primary filter plate 104 and the secondary filter plate 106 and then enters the rainwater filtering box 102; then enters the rainwater precipitation box 108 through the overflow pipe 107; finally, the water pump 110 is started, at this time, the rainwater in the rainwater precipitation box 108 enters the water storage tank 113 through the water pump water conveying pipe 111 and the water storage water conveying pipe 112 for storage, when it is needed to use, the high-pressure drainage pump 114 is started to pump out the rainwater stored in the water storage tank 113 through the drainage pipe 115 and the water outlet pipe 116 for use, such as watering flowers, washing cars, etc.

[0036] Embodiment Two

[0037] On the basis of the first embodiment, the roof rainwater collecting and utilizing system further comprises a plurality of overflow plates 109 arranged in a stepped manner in the rainwater precipitation box 108,

[0038] The height dimension of the overflow plate 109 gradually decreases from the side of the overflow pipe 107 to the side of the water pump water delivery pipe 111.

[0039] The rainwater precipitation tank 108 is rectangular (length 8-10 meters), and the overflow plate 109 is 0.5-1.2 meters, so that the rainwater can be precipitated layer by layer, and the rainwater purification function can be realized.

[0040] Example Three

[0041] On the basis of Example Two, the roof rainwater collection and utilization system further comprises a high-pressure sewage pump 117 arranged on one side of the foundation pit 101, a sewage discharge pipe 118 and a sewage delivery pipe 119 connected with the high-pressure sewage pump 117, a main sewage delivery pipe 120 connected with the sewage delivery pipe 119, a first branch sewage delivery pipe 121 connected with the main sewage delivery pipe 120 at both ends and the rainwater filtration tank 102, and a plurality of second branch sewage delivery pipes 122 connected with the main sewage delivery pipe 120 at both ends and the rainwater precipitation tank 108.

[0042] The connection ends of the second branch sewage delivery pipes 122 and the rainwater precipitation tank 108 are respectively located between the overflow plates 109.

[0043] After the rainwater collection is completed during a single rainfall, the high-pressure sewage pump 117 is started to pump out the sludge in the rainwater filtration tank 102 and the rainwater precipitation tank 108 through the sewage discharge pipe 118, the sewage delivery pipe 119, the main sewage delivery pipe 120, the first branch sewage delivery pipe 121 and the plurality of second branch sewage delivery pipes 122, so that the rainwater collection is not affected by the next rainfall, the contaminated rainwater is collected, and the clean rainwater is collected. In addition, the emptying of the rainwater filtration tank 102 and the rainwater precipitation tank 108 prevents the mixture of sludge and water inside from producing a peculiar smell due to microbial fermentation, which affects the water quality of the collected rainwater.

[0044] In addition, the mesh number of the primary filter plate 104 is less than that of the secondary filter plate 106, so that double filtration of foreign matters in the rainwater is completed. In addition, the primary filter plate 104 and the secondary filter plate 106 are both provided with a hand-held handle structure, so that the primary filter plate 104 and the secondary filter plate 106 can be easily removed from the rainwater filtration tank 102 for unblocking or cleaning the inside of the rainwater filtration tank 102.

[0045] In addition, the size of the rainwater filtration tank 102 is smaller than that of the rainwater precipitation tank 108, so that a large amount of rainwater is prevented from being collected in the rainwater filtration tank 102.

[0046] The roof rainwater collection and utilization system has a reasonable and simple overall design structure, and is convenient for construction.

[0047] It has to be understood that, in the present text, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusions, such that processes, methods, articles, or devices that include a series of elements are not limited to those elements, but are also inclusive of other elements not expressly listed, or inherent to such processes, methods, articles, or devices. Without further limitation, an element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, article, or device including the element.

[0048] It will be apparent to those skilled in the art that the present application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The present application thus should not be considered limited to the embodiments described herein, but rather should be understood to cover all modi- fications, equivalents, and alternatives falling within the sphere of the equivalent elements of the claims.
