A kind of roof rainwater collecting device
Technical field
The utility model relates to a kind of roof rainwater collecting device.
Background technology
Water resource is the resource of most critical among the human lives, sleeping national urbanization and socioeconomic development, the demand of non-agricultural irrigation water is in rapid increase, and agriculture and many water contradictions such as industry, rural area and city, production and life, production and ecology are further aggravated.Nowadays, national actual available water resource approaches the upper limit of rationally utilizing the water yield, and the water resources development difficulty is very big.And pollution is in various degree all received in national most of river and waters, and the deterioration of water environment has destroyed the ecological homeostasis, and Situation of water resources is more severe, and water resource is nervous, and water pollution has seriously become the important restriction factor of China's sustainable development.Each metropolis, the whole nation all faces the present situation of this shortage of water resources in various degree, Constructing Water-saved Society how, and improving water utilization rate is an extremely urgent important topic.The amount of precipitation of southern area is relatively large, and do not have now suitable method that it is collected and be used, but in the sewer of letting things run their course.If rainwater recycle can be got up, through processing such as sedimentation and filtration sterilizations, become living water use, or directly as irrigation water, then can solve the problem that water resource lacks.
The utility model content
For the problem of existing above-mentioned proposition, the utility model provides a kind of roof rainwater collecting device.
The utility model is achieved through the following technical solutions: a kind of roof rainwater collecting device is characterized in that: comprise catch basin, gutter, reservoir.Catch basin is arranged on roof edge, and the catch basin bottom surface is lower than the roof upper surface, and gutter is installed in catch basin below, and an end connects with catch basin and is connected, and the other end is connected with indoor reservoir perforation.
Further, indoor location has tee piece, and three ports of tee piece respectively are equipped with gutter, and three gutters connect with catch basin, reservoir, sewer respectively and are connected.
Further, be provided with only draining valve on the gutter between tee piece and the sewer.
Further, be provided with only draining valve on the gutter between tee piece and the catch basin.
Further, described reservoir is at least one.
Further, described catch basin is shaped as square groove.
Perhaps this catch basin is arc-shaped slot, is installed in the roof edge below.
Or this catch basin for around build the roof have water blockoff to enclose base, gutter passes the roof and connects with it connection.
The beneficial effects of the utility model are:
1, simple in structure, easy for installation, cost is low, can be according to building frame structure difference, age of the building length difference, construction matter
The corresponding embodiment of amount different choice;
2, the rainwater centralized collection can be utilized, meet the theory of environment-friendly water-saving.
In order to understand better and to implement, describe the utility model in detail below in conjunction with accompanying drawing.

The specific embodiment
Embodiment one
Fig. 1 is the schematic diagram of the roof rainwater collecting device 10 of the utility model embodiment one.This roof rainwater collecting device 10 comprises catch basin 11, gutter 12 and reservoir 13.Described catch basin 11 is arranged on 1A edge, roof, and catch basin 11 bottom surfaces are lower than roof 1A upper surface, and gutter 12 is installed in catch basin 11 belows, and an end and catch basin 11 connects and be connected, and the other end passes exterior wall 1B and is connected with indoor reservoir 13 perforations.
Further, indoor location has tee piece 14, and 14 3 ports of tee piece are separately installed with gutter 121, gutter 122, gutter 123, gutter 121 connect with catch basin 11 and are connected, gutter 122 connects with reservoir 13 and is connected, and gutter 123 connects with sewer 1C and is connected.
Further, gutter 122 stage casings are equipped with only draining valve 1221.
Further, gutter 123 stage casings are equipped with only draining valve 1231.
Further, described reservoir 13 quantity are at least one.
Further, described catch basin 11 is shaped as square groove.
The rainwater that gathers on the roof 1A when raining is closed when ending draining valve 1231 from marginal flow to catch basin 11, and when ending draining valve 1221 and opening, rainwater enters reservoir 13 by gutter 121 and 122.If the excessive drainage speed that surpasses gutter 122 of rainfall, perhaps reservoir 13 capacity are full, then will end draining valve 1231 and open, and end draining valve 1221 and close, and rainwater can enter sewer 1C by gutter 121 and gutter 123.If catch basin 11 needs retaining, then will end draining valve 1221 and end draining valve 1231 and close.
The rainwater that catch basin 11 and reservoir 13 are collected can filter through precipitation, is used for living water use after the sterilization, also can be directly used in agricultural irrigation water.The roof rainwater collecting device of this structure is applicable to newly constructed house, can simultaneously catch basin be built during housing construction.
Embodiment two
Fig. 2 is the structural representation of the utility model embodiment two.The roof rainwater collecting device of itself and embodiment one is roughly the same, and its difference only is: this catch basin 21 is arc-shaped slot, is installed in below, 2A edge, roof.The roof rainwater collecting device of this structure is applicable in old house transformation is installed.
Embodiment three
Fig. 3 is the structural representation of the utility model embodiment three.The roof rainwater collecting device of itself and embodiment one or embodiment two is roughly the same, its difference only be described catch basin 31 for around build and have the water blockoff base to enclose 311 roof 3A, it is indoor that gutter 32 is installed in, and passes roof 3A and connect with it that to connect the bottom identical.The roof rainwater collecting device of this structure is applicable to the building that the existing water blockoff in roof encloses base or embodiment two described roof rainwater collecting devices can't be installed.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
