Embodiment 1

[0039] like figure 1 As shown in -2, a water quality ecological restoration device includes a main controller part 2, a power supply part, a motor drive part, a diversion structure part, a buoy body, and a sensor monitoring part.

[0040] The main controller part includes a GPRS module and a bluetooth module. The data receiving end of the remote data center 16 utilizes the GPRS wireless transmission mode to remotely monitor the data collected by the sensor or switch the motor 3 in real time. The collected data includes, water temperature, motor current, motor speed, Battery voltage, including dissolved oxygen content, COD content, NH 3 -N content, TP content, TN content, chlorophyll a content and other water quality parameters. In the field, through Bluetooth data transmission, combined with the supporting mobile phone APP18, the switch and speed regulation of the motor of the device are realized, which is convenient for on-site testing and comparison. At the same time, the ...

Embodiment 2

[0050] like figure 2 Shown, a kind of water ecology restoration system, this restoration system comprises remote data center 16, the water ecology restoration device 17 and supporting mobile phone APP among the embodiment 1;

[0051] The water ecological restoration device contains a telemetry terminal. The data receiving end of the remote data center uses GPRS wireless transmission to remotely measure the data to be monitored or switch the motor in real time. The monitored data includes dissolved oxygen content, COD content, NH 3 -N content, TP content, TN content, chlorophyll a content, motor current, motor voltage, motor speed, battery voltage. Through the matching mobile phone APP, the switch and speed regulation of the device motor and the acquisition of water quality parameters are realized through Bluetooth, which is convenient for on-site testing and comparison results. The remote data center or the mobile APP can configure the threshold and parameters of the system ...

Embodiment 3

[0053] A kind of water ecology restoration method, this water ecology restoration method is based on the water ecology restoration system in embodiment 2, concrete steps are as follows:

[0054] S1. Configure the threshold and parameters of the system operation through the remote data center or the supporting mobile phone APP, including the physical quantity to be sampled, the sampling period, and the motor switching period;

[0055] S2. Adopt a closed-loop control strategy, take the motor speed and rotation time as the control amount, and take the dissolved oxygen content as the feedback amount. When the dissolved oxygen content is higher than the set threshold, the motor is turned off and the device is in standby mode; when the dissolved oxygen detection device detects When the oxygen content is low, the device enters the working mode, and the influence of speed and time on dissolved oxygen is comprehensively considered, and it is optimally controlled;

[0056] S3. The main ...

Abstract

The invention discloses a water ecological restoration device, which comprises a main controller part, a power supply part, a motor driving part, a flow-dividing structure part, a buoy body and a sensor detection part. The invention provides a water ecological restoration system, which comprises a remote data center, the water ecological restoration device and a matched APP. The invention furtherdiscloses a water ecological restoration method. The water ecological restoration method specifically comprises the steps that thresholds and parameters for system operation are configured; a main controller receives an instruction of an upper computer and controls motor impellers to rotate; the impellers rotate to drive a water body to form a transverse flow and a longitudinal flow; the water ecological restoration device promotes exchanging of a shallow water body and a deep water body by generating transverse water circulation and longitudinal water circulation, layering of the water bodiesis eliminated, homogenization of the water bodies is promoted, and the dissolved oxygen content of the deep water body is increased significantly. According to the water ecological restoration device, system and method, a closed-loop control strategy is adopted, exchanging of the shallow water body and the deep water body is promoted by forming longitudinal water circulation and transverse watercirculation in the water bodies within the certain range, the dissolved oxygen content of the water bodies is increased, the water quality is improved, and water ecological restoration is achieved.

Description

technical field [0001] The invention relates to the technical field of water quality ecology, in particular to a water ecology restoration device, system and restoration method thereof. Background technique [0002] At present, the problem of black and odorous water has become one of the main environmental problems in my country. Reservoirs, urban landscape pools, artificial lakes, etc. are prone to water eutrophication or black and odorous water. One of the main reasons for the formation of black and odorous water bodies is the lack of oxygen in the water body. The stratification of the water body further exacerbates this phenomenon, resulting in the proliferation of anaerobic organisms in the anoxic water body, especially in the deep water body, causing serious water changes. The country has invested a lot of manpower and material resources in the treatment of black and odorous water bodies, and has achieved certain results, but the effects are often not long-lasting, and ...
