Background technique
In a city, drinking water and salt water (middle water) supply generally is to distribute to numerous buildings by the foggara network of complexity to use.For guaranteeing the reliability of drinking water and salt water supply, water flow velocity, hydraulic pressure and the leakage situation of monitoring under ground piping are extremely important.Even if the market has different sensors and instrument to measure water flow velocity, hydraulic pressure and leakage situation, be very difficult but sometimes will obtain continuous and suitable power supply supply along the line at pipeline.On the one hand, although pipe network may have the high voltage supply cable along the line, therefrom obtain a small amount of electric power and supply monitoring equipment and in engineering, safety, cost and management, all have any problem.On the other hand, the current in the water pipe are a kind of cleaning and the energy continuously just, and consuming the part head is enough to supply normally stable work of monitoring equipment.In addition, have unnecessary head on some water supply networks in the open air, this head can convert power supply to fully to the application of detection and field illuminating etc.
Compare with general hydroelectric power system, utilize the requirement of generating electricity of current in the water pipe can not pollute water (especially drinking water), can not cause leakage, can not cause too large loss of pressure head and under relatively low flow velocity, operate.The system that utilizes the current in the water pipe to generate electricity can be divided into non-inline enclosed and inline enclosed two classes.Non-inline closed system needs an existing pipeline excision part is changed the pipeline that includes water turbine.The method is because pipework is complicated, and required engineering space is large and engineering time is longer, carries out such installing engineering meeting in the thickly populated city pedestrian and traffic are made troubles.Inline closed system only needs trunnion on existing pipeline punches and welds, and then water turbine is inserted and just can.The method is because pipework is simpler, and required engineering space is less and engineering time is shorter, is particularly suitable for carrying out in the thickly populated city installing engineering.
