SELF-POWER GENERATION TYPE PIPE SENSOR, DISASTER DETECTION SYSTEM, AND SELF-POWER GENERATION TYPE PIPE ATTACHMENT DEVICE

摘要

[Problem] To reduce the cost and labor of manufacturing and installation for equipping a plurality of types of detection units and a device for obtaining the data of the detection units and to construct a disaster prevention system in which a plurality of sensors are installed at every predetermined section of a piping path. [Solution] A self-power generation type pipe sensor comprises: a pair of connection flanges (1) connected to a divided portion where a piping path (P) is divided at a halfway point thereof; an inner pipe (2) for connecting the divided portion of the piping path (P) so that a fluid can flow; a bypass pipe (3) having a flow path that is branched and bypassed from an upstream side position of the inner pipe (2) and reconverges at a downstream side position of the inner pipe (2); a rotating body (4) provided in the flow path of the bypass pipe (3) around the inner pipe (2) and rotated by the fluid flowing through the bypass pipe (3); an electromotive device (5) generating electricity by the rotation of the rotating body (4); and at least either a detector (6) or a receiving device (8) electrically connected to the electromotive device (5).
