The utility model has the advantages that: since the collectors are arranged on the ground surface, not only the construction is convenient, the construction cost is saved, but also precious underground space resources are saved, and it is convenient for later cleaning and maintenance.

Description

A Concealed Sponge City Rainwater Collector

technical field

The utility model relates to the construction field, in particular to a rainwater collection device.

Background technique

At present, the state strongly supports and encourages the construction of sponge cities; sunken green spaces are set around many buildings to use rainwater overflow to collect rainwater in the park; as shown in Figure 2, the prior art includes sunken green spaces, a plurality of overflow wells are set in the sunken green spaces, and the lower end of the overflow wells communicates with rainwater collection wells; Tension, if it is located below the underground parking lot, it will inevitably cause construction inconvenience and greatly increase the construction cost because it is arranged in a deep underground position; 2. Many overflow wells protruding from the sunken green space are set around the building, which seriously affects the beauty of the building environment.

Utility model content

In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a kind of concealed sponge city rainwater collector, including sinking green land, the upper end of the slope of the sunken green land is provided with a rainwater collection box, and the rainwater collection box is provided with a rainwater collection port near the side slope, and the rainwater collection port is axially connected with the rainwater collection box; The level height of the rainwater collection well.

A submersible pump is arranged in the rainwater collection well, and the submersible pump is connected with the irrigation pipeline below the surface green layer through a drainage pipe; valves are arranged at both ends of the drainage pipe.

The valve arranged on the drainage pipeline of the rainwater collection well is an electric control three-way valve.

There are multiple rainwater collection boxes, which are uniformly connected to rainwater collection wells by pipes.

The rainwater collection port is axially connected to the rainwater collection box, and a supporting structure is arranged at the lower end of the rainwater collection port.

The utility model has the advantages that: since the collectors are arranged on the surface layer, not only the construction is convenient, the construction cost is saved, but also precious underground space resources are saved, and it is convenient for later cleaning and maintenance. In addition, the use of drainage pipes to achieve non-powered output of rainwater not only saves resources, but also ensures silence and optimizes the environment.

Detailed ways

The utility model is described in detail below in conjunction with the embodiments and accompanying drawings, and the described embodiments are only a part of the embodiments of the utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. As shown in the figure, a sunken green space 1 is set in the courtyard next to the building 6, and the sunken green space can be a green belt or an artificial lake; a rainwater collection box 7 is arranged at the upper end of the slope of the sunken green space, and a rainwater collection port 8 is arranged on the side of the rainwater collection box near the slope, and the rainwater collection port is axially connected with the rainwater collection box; such a structure can ensure that the surface of the rainwater collection port is parallel to the side slope to achieve an aesthetic effect; 1. Such as sand and gravel cement to ensure the above state;

Described rainwater collection box is connected with rainwater collection well 5 by pipeline 9, and described rainwater collection well is arranged on the lower end of ground layer 10, the upper end of green space support layer 3;

A submersible pump 13 is arranged in the rainwater collection well, and the submersible pump is connected with the pouring pipeline below the surface green layer through the drainage pipeline 12 .

In order to prevent the noise of the submersible pump from affecting the living environment, valves are provided at both ends of the drainage pipe provided in the rainwater collection well. When in use, first use the submersible pump to fill the drainage pipe with water, and then open the valves at both ends of the drainage pipe, so that the siphon phenomenon can be used, and the water in the rainwater collection well flows into the lower part of the green layer; the valve on the drainage pipe in the rainwater collection well can use an electronically controlled three-way valve. Connect the end of the collection well.
