Detailed Description

The water storage mechanism comprises a water storage mechanism and a power generation mechanism and is characterized in that the water storage mechanism comprises a water storage tank 1, a water inlet pipe 2 and a siphon pipe 3, the water inlet pipe 2 is arranged at the top of the water storage tank 1, the siphon pipe 3 penetrates through the bottom of the water storage tank 1 and is connected with a drain pipe 4 below the water storage tank 1, the other end of the drain pipe 4 is communicated with the power generation mechanism, and when the water level of rainwater injected from the water inlet pipe 2 is lower than the bent part at the upper end of the siphon pipe 3, the siphon phenomenon cannot occur because air exists in the siphon pipe 3. When the level of the rainwater is higher than the bent portion above the siphon tube 3, the siphon tube 3 is filled with water, a siphon phenomenon occurs, and the water in the water storage tank 1 automatically flows out of the siphon tube 3 and into the drain tube 4 until the water level drops below the elbow inlet of the siphon tube 3. Then, the process of the second water storage is started again, the siphon phenomenon occurs again after the water storage is full, and the water discharge amount of each time can be controlled by adjusting the distance between the top end of the siphon pipe 3 and the bottom end of the water storage tank 1.

The power generating mechanism comprises a gear box 5 and an impeller 6, wherein the impeller 6 is arranged on a power input shaft 7 of the gear box 5, the gear box 5 is a prior art, and particularly, the gear box part of the related patent with the application publication number of CN 109812371A can be referred.

The half part of the impeller 6 is arranged right below the drain pipe 4, the other half part of the impeller 6 is arranged in the gear box 5, and the impeller 6 is distributed in a balanced manner, so that potential energy of rainwater can be converted into effective mechanical energy of the impeller 6, the phenomenon that the driving force of the impeller 6 is too large and the required rainwater amount is larger can be avoided, and less rainwater can be effectively utilized to generate electricity.

Retaining mechanism still includes emergent drainage module, prevents the jam of

siphon

3 and 1 ponding of water storage box that arouses and unable discharge, and emergent drainage module is including cursory 8, connects rope 9, valve plug 10, emergent pipe 11, and the one end setting of emergent pipe 11 is in water storage box 1's bottom, and emergent pipe 11's the other end and the middle part intercommunication of drain pipe 4, and emergent pipe 11 sets up valve plug 10 with 1 junction of water storage box, and valve plug 10 is connected with and connects rope 9, connects cursory 8 is connected to the other end of rope 9. When siphon 3 blockked up, can make 8 pulling connection ropes 9 of cursory after the ponding volume reaches the take the altitude, and then pull up valve plug 10 and leave water storage box 1, make ponding discharge the middle part of drain pipe 4 from emergent pipe 11 to flow into power generation facility and generate electricity again, improve device's security.

The valve plug 10 is articulated with water storage tank 1, and when ponding discharge back water level decline, valve plug 10 can close automatically once more.

The junction of inlet tube 2 and water storage tank 1 is provided with detachable filter screen 12 to the debris that take down are left from eminence such as roof to the rainwater of filtering, and the accessible is dismantled and is carried out the change of filter screen 12.
