Problems solved by technology

Although the system can store rainwater in external storage tanks, it does not make effective use of the water retention and storage capacity of the municipal culvert or the pipe network itself. Therefore, there are still problems of high construction costs and insufficient effects

Embodiment 1

[0045] like figure 1 , figure 2 As shown, in this embodiment, a bottom horizontal shaft 41 is provided at the bottom of the gate, and the opening and closing mechanism 4 is a bottom horizontal shaft turning device driven by a motor, hydraulic pressure or air pressure. The bottom horizontal shaft turning device corresponds to the gate and is arranged on the outside of the underdrain 1. When used as figure 1 As shown by the arrow of the middle gate 2, the bottom horizontal axis turning device drives the gate to turn to one side, thereby opening the reservoir 3 between the gates at all levels to realize water storage or discharge.

[0046] The bottom horizontal axis turning device of this embodiment is applied in the underdrain 1, of course, it can also be used in municipal rainwater pipe networks such as pipelines, and at this time, the shape of the gate 2 needs to match the cross section of the pipeline.

[0047] like Figure 13 As shown, the present embodiment is equipped ...

Embodiment 2

[0051] like image 3 , Figure 4 As shown, in the present embodiment, the upper part of the gate 2 is provided with a lifting and horizontal guide rail 42, and the opening and closing mechanism 4 is a lifting and horizontal opening and closing equipment driven by a motor, hydraulic pressure or air pressure, and the lifting and horizontal opening and closing equipment is arranged on the top of the gate. The opening and closing mechanism 4 drives the gate 2 to move up along the horizontal guide rail 42, which is similar to the structure and action of the existing rolling door or garage sliding door. When in use, the lifting-horizontal opening and closing equipment drives the gate 2 to move upward through a pull rod, cable or chain, and the gate 2 moves along the lifting-horizontal guide rail 42 from vertical to curved or horizontal, thereby opening the reservoir 3 . The ascending and horizontal guide rail 42 can be arranged on the upper side of the gate 2 or tilt outward from t...

Embodiment 3

[0053] like Figure 5 , Image 6 As shown, in the present embodiment, the gate 2 is connected to the support arm 43, and the opening and closing mechanism 4 is a swing-up opening and closing device driven by a motor, hydraulic pressure or air pressure. During use, the swing-up opening and closing equipment of the support arm drives the support arm 43 to move through a pull rod or a drag cable or a chain, and the support arm 43 drives the gate to rotate upwards, thereby opening the reservoir 3 . One or more sets of support arms 43 can be used in this embodiment, and the connection end of the support arms 43 relative to the gate 2 is hingedly installed with the side wall of the underdrain 1 .

Abstract

The cascade water blocking and water storage system used for municipal rainwater pipe network includes water blocking system and water storage system. The water storage system includes a reservoir, which is composed of a water blocking device and a rainwater culvert or a pipe network. The water blocking facility is equipped with an opening and closing mechanism for opening or closing the gate, and is equipped with a water level sensor, a flow rate sensor and a gate. The position sensor is used to measure and obtain signals such as water level, water level rising speed, water flow speed and valve position. On the basis of retaining the functions of the original municipal culverts and pipe network to discharge rainwater, this system has newly set up water blocking, water regulation and storage facilities, and is equipped with an intelligent control system to realize cascade automatic regulation and storage of rainwater in municipal facilities without the need for new storage. Larger cost investments such as pools and rainwater tanks have also unearthed new functions of municipal rainwater facilities, giving full play to the implementation value of existing urban infrastructure, and accelerating the construction and realization of sponge cities.

Description

technical field [0001] The invention relates to an urban rainwater utilization system, which belongs to the field of municipal engineering, and in particular to a cascaded water retention and storage system for municipal rainwater pipe networks. Background technique [0002] In 2015, the "Opinions on Promoting the Construction of Sponge City" issued by the General Office of the State Council (Guo Ban Fa [2015] No. 75) required that "comprehensive measures such as 'seepage, stagnation, storage, purification, use, and discharge' should be adopted to maximize the Reduce the impact of urban development and construction on the ecological environment, and by 2020, 70% of the rainfall will be absorbed and utilized locally." At present, in the process of sponge city construction, most of the water storage measures are to use new underground water storage facilities (commonly used in the form of plastic module water storage and underground storage tanks) to increase urban water stora...
