A hydroelectric runoff automatic monitoring device

Abstract

The invention discloses a hydroelectric power generation runoff automatic monitoring device, which is mainly used for automatic monitoring of non-point source polluted runoff in small watersheds. The system consists of runoff inlet sleeve, control module, rain gauge, multi-parameter water quality monitor, flushing connection hole, grille, sand outlet, water turbine, hydroelectric generator, current controller, battery, solar power generation panel, heat dissipation shield, Flow meter, liquid level sensor and housing. The invention provides the device with electricity other than solar energy through the electric energy generated by hydraulic power; in order to prevent the water turbine of the device from being damaged by sand and stones, a grid is provided for protection; in order to prevent the grid from being blocked, the rainwater in the rain gauge is used to adhere to the grid clean the sand and gravel; the battery, current controller, generator and other heating units are protected by a strong anti-corrosion heat dissipation shield; in addition to monitoring program design, data storage and remote transmission, the control module can also set the minimum operating threshold, thereby saving energy consumption of the device as much as possible. The above design provides guarantee for the device to perform unattended automatic monitoring of runoff in the field as much as possible.

Description

technical field [0001] The invention relates to the technical field of surface source pollution runoff monitoring in watersheds, and more specifically, to a hydroelectric power generation type runoff automatic monitoring device. Background technique [0002] At present, non-point source pollution in the watershed is an important source of water pollution. Agricultural production water and domestic sewage in the watershed are discharged into surface water bodies through surface runoff, leading to eutrophication of important lakes and reservoirs, and a decline in the quality of the regional ecological environment. Through non-point source runoff pollution monitoring, the degree of source pollution under different conditions can be clarified, so that corresponding prevention and control measures can be taken. [0003] The conventional runoff monitoring of non-point source pollution in the watershed is that when rainfall occurs in the watershed and surface runoff is formed, the ...

Problems solved by technology

Due to the remote location of the watershed, the non-point source runoff monitoring is not timely. If the monitoring personnel are required to rush to the scene to wait in advance, the input of manpower and financial resources will be increased.

At the same time, the traditional rainfall data comes from the local meteorological or environmental protection departments, and the location of the monitoring point and the location of the watershed have spatial differences, resulting in errors in the rainfall data

On the other hand, artificial runoff flow readings will also produce errors. Therefore, research on a real-time and accurate automatic monitoring device for non-point source pollution runoff in the watershed, and realize the storage and remote transmission of monitoring data, is of great significance for the prevention and control of non-point source pollution in the watershed. important meaning

Most of the existing automatic runoff monitoring devices use solar panels to provide power for the equipment in the field. This method is difficult to provide sufficient power for the equipment during the rainy season, resulting in the failure of the equipment to operate normally. Therefore, it is necessary to use other means for The device provides power

[0004] To sum up, how to solve the power supply demand of the equipment in the field to the greatest extent and save the power consumption of the device while overcoming the problems of difficult real-time monitoring of non-point source pollution runoff in the existing watershed, large monitoring errors, and large manpower input has become Current technical issues to be resolved
