| (54) | SELF-POWER GENERATION TYPE PIPE SENSOR, DISASTER DETECTION SYSTEM, AND SELF-POWER GENERATION TYPE PIPE ATTACHMENT DEVICE |
| (57) [Object] To construct a disaster prevention system in which the trouble and costs
of production and installment for providing several types of detection portions and
their data acquisition devices can be reduced, and a plurality of sensors are provided
for each predetermined section of the pipeline. [Solution] A pair of connection flanges
1 which is flange-connected to a section part dividing a pipeline P in the midst of
the same, an inner pipe 2 which connects the section part of the pipeline P in a manner
of allowing fluid circulation, a bypass pipe 3 having a flow path branching in a bypassing
manner from a position of the inner pipe 2 closer to the upstream side, and merging
again in a position of the inner pipe 2 closer to the downstream side, and a rotor
4 provided within the flow path of the bypass pipe 3 about the inner pipe 2 and rotates
by the fluid circulation to the bypass pipe 3, an electromotive device 5 which generates
electricity by the rotation of the rotor 4, and at least either the detector 6 or
power receiving device 8 which is electrically connected with the electromotive device
5 are provided.
