Specifically, in order to ensure the medium to be in overcurrent contact with the power generation device 1, the fixed shaft 113 is disposed in a direction such that the first overcurrent surface 112B is parallel to the connecting through holes at both ends of the module case 111 when the generator set 112 swings to the lowest position.
The junction of the first flow surface 112B and the second flow surface 112C is a sealed junction, which does not allow water to pass through the junction.
The data acquisition assembly 2 comprises two pressure sensors which are respectively arranged in front of the valve and behind the valve, and specifically, the pressure sensor in front of the valve is arranged at the front end of a connecting hole of an external pipeline in front of the valve, namely, water flow firstly passes through the pressure sensor and then enters the valve body and the external pipeline; the pressure sensor behind the valve is arranged at the rear end of a connecting hole of an external pipeline behind the valve, namely, water flow flowing back to the valve body from the external pipeline needs to be subjected to data acquisition through the pressure sensor.

Specifically, the water flows through the multi-function pressure reducing valve, contacts the first and second overflow surfaces 112B and 112C of the power generation device, when the medium flow velocity is larger, the impact force of the water flow is buffered by the elastic action of the first flow passing surface 112B, when the flow velocity of the water flow is further increased, the water flow pushes the generator set 112 to tilt around the fixed shaft 113 as a pivot, and the pressure of the water flow forces the second end 115C of the return spring to be subjected to a certain pressure to generate an elastic force and deform, and because of the angled gap formed between the genset 112 and the assembly housing 111, some of the water will flow through the gap, the flow of water through the genset impeller will be correspondingly reduced, and the thrust of the water flow flowing through the impeller of the generator set and the angle of the generator set 112 are changed, so that the stress of the impeller is correspondingly reduced, the rotating speed of the impeller is reduced to a certain extent, and the current generated by the power generation assembly is not increased due to the great increase of the flow velocity of the water flow.
When the velocity of water flow diminishes, rivers will slowly reduce to generating set 112's pressure, until being less than the resilience force of return spring, at this in-process, generating set passes through the resilience force of return spring, rotate along fixed axle 113 along with pendulum rod 114, slowly get back to vertical position from the inclined position, along with the clearance between generating set 112 and subassembly shell 111 reduces gradually, the volume that rivers circulate in the clearance reduces, correspondingly, the rivers of impeller of flowing through will become many, rivers change the corresponding increase of messenger's impeller atress to the thrust of impeller and generating set's angle, the rotational speed of further increase impeller, the electric current that makes electricity generation subassembly 11 produce does not reduce because of the reduction of the velocity of water flow.
The current generated by the final power generation assembly does not change suddenly due to the sudden change of the flow speed of the water flow, so that the effect of stabilizing the current is realized.
The battery assembly 12 comprises a rectifying module, a filtering module, a voltage reduction module, a voltage boosting module and a rechargeable battery (all not shown) which are connected in sequence, and the rechargeable battery is electrically connected with the data acquisition assembly 2 and the data processing and display terminal respectively.
