Description

Technical Field

[0001] The utility model belongs to the technical field of annual runoff volume control rate detection, and particularly relates to a detection device for obtaining the annual runoff volume control rate. Background Art

[0002] In a sponge city, rainwater will experience different flow directions and treatment processes after falling to the ground. First, a part of the rainwater will undergo evaporation and transpiration and directly return to the atmosphere; another part of the rainwater will infiltrate into the ground and enter the soil and groundwater layer. At the same time, part of the rainwater forms surface runoff on the ground, and a part of the surface runoff will flow into low impact development (LID) facilities and be stored; another part of the surface runoff will flow into adjacent rain wells or rain drainage systems and finally be discharged into rivers, lakes or the ocean.

[0003] In a sponge city, the annual runoff volume control rate is an index used to describe the control efficiency of the city on rainfall runoff volume, and it can represent the reduction degree of rainfall by the city. The annual runoff volume control rate is specifically expressed as: within one year, the ratio of the rainfall controlled in the city to the annual rainfall. Generally speaking, the annual runoff volume control rate is calculated in the urban waterlogging model, but there are errors in the annual runoff volume control rate obtained in this way; in actual projects, the process of manually obtaining the annual runoff volume control rate data is very cumbersome, the amount of data to be processed is large, and it is impossible to ensure the acquisition of stable runoff data.

[0004] Therefore, it is necessary to provide a detection device for obtaining the annual runoff volume control rate. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a detection device for obtaining the annual runoff volume control rate, so as to stably obtain runoff data, accurately detect the annual runoff volume control rate, and thus improve the management quality.

[0006] The purpose of the utility model is to provide a device for evaluating the annual runoff volume control rate aiming at the deficiencies of the prior art, so as to achieve the purpose of stably obtaining runoff data.

[0009] Preferably, in order to avoid the influence of suspended solids on the monitoring of the water flow velocity and the water level height, a grille plate is arranged near the inner wall of the water volume well on the water inlet pipe, and the backward extension of the grille plate can better stabilize the water flow.

[0010] Preferably, in order to further stabilize the water flow liquid level and consume the kinetic energy of the water flow, the buffer assembly comprises a fan blade, a support rod, a power generation motor, a transmission device and a rotating shaft, and the kinetic energy of the water flow is consumed by the fan blade.

[0011] Preferably, in order to reduce energy consumption, the rainwater flows through the fan blade to drive the transmission device, and the transmission device drives the power generation motor to generate electricity, which can be used as a backup power supply in cooperation with a storage battery; the solar panel arranged on the on-line rainfall detection device can also generate electricity, which can be used as a backup power supply in cooperation with a storage battery.

[0012] Preferably, in order to facilitate the measurement of the flow rate in the non-full pipe condition, a non-full pipe electromagnetic flowmeter is adopted. The non-full pipe electromagnetic flowmeter is composed of an electromagnetic flow velocity sensor and a pressure type water level sensor, and the measured data is used to calculate the flow rate by the velocity-area method.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the buffer assembly rectifies and dissipates the energy of rainwater, slows down the rolling water flow, and can reasonably utilize the water flow resources.
