The invention discloses a landscape type rainwater accumulation device capable of being used for garden
irrigation. The landscape type rainwater accumulation device comprises a
water storage pool, a plurality of grooves are symmetrically formed in the
water storage pool, toothed bars are fixedly connected to one side walls of the multiple grooves, a fixing frame is arranged at the outer side wallof the
water storage pool, the fixing frame is arranged in a regular polygon shape, and a plurality of tooth rollers are rotationally connected to the fixing frame. According to the landscape type rainwater accumulation device, in rainy days, a shielding plate can be pulled to be opened in virtue of the
gravity effect increased by water storage of an annular
water storage tank, and the
water sampling area can be increased; the opening mode of the shielding plate is like
lotus blossom so that opening of the shielding plate is very attractive; and the shielding plate is like a
bud when closed, so that the shielding plate can also be used as a landscape in a garden, and the ornamental value of the garden can be improved. After rain is stopped, in virtue of elastic force of a torsional spring,a top plate is extruded through reset of the shielding plate, automatic
pollution discharge is achieved, the whole processes of opening for water storage and closing for
pollution discharge are automatically carried out, manual operation is not needed, and therefore the landscape type rainwater accumulation device is very easy and convenient to use.
