Rainwater desilting basin device

Abstract

The invention relates to the field of rainwater collection and utilization, in particular to a rainwater desilting basin device. The rainwater desilting basin device comprises an energy dissipation unit and a desilting unit, wherein the energy dissipation unit comprises an energy dissipation well; a water inlet pipe is arranged at one side of the energy dissipation well; the desilting unit comprises a desilting basin and a silt collecting groove formed in the desilting basin; the well bottom of the energy dissipation well is lower than the basin bottom of the desilting basin; a partition wall is arranged between the energy dissipation well and the desilting basin; the energy dissipation well and the desilting basin are communicated through a flow passing opening formed in the partition wall; the width of the desilting basin is greater than the width of the energy dissipation well; the two side walls of one end, near the energy dissipation well, of the desilting basin are inwards contracted in a direction facing the energy dissipation well and are finally connected with the two side edges of the partition wall; the two side walls of one end, far away from the energy dissipation well, of the desilting basin are gradually and inwards contracted in the direction along the water flow; a water outlet pipe is connected onto the basin wall of one end, far away from the energy dissipation well, of the desilting pool; the basin bottom of the desilting basin arranged between the partition wall and the silt collecting groove is downwards inclined to the silt collecting groove from the partition wall; the bottom of the silt collecting groove is provided with a silt discharge pipe used for outwards discharging silt. The rainwater desilting basin device has the advantage that the desilting effect is improved.

Description

technical field [0001] The patent of the present invention relates to the field of rainwater collection and utilization, in particular to a rainwater sedimentation tank device. Background technique [0002] Facing the increasingly severe contradiction between supply and demand of water resources, how to make full and effective use of rainwater resources has become one of the hot topics in the development of water resources in my country. High-speed urbanization and inappropriate urban pattern construction concepts have led to a rapid increase in the number and proportion of impermeable underlying surfaces (the earth's surface that is in direct contact with the lower atmosphere), and the urban heat island effect has become apparent, which has changed the urban rainwater environment and operating laws, resulting in On the one hand, the surface runoff increases and the runoff coefficient increases. On the other hand, the rainwater confluence time shortens, the peak flow increas...
