The working principle of the bidirectional tidal power generation device based on the ratchet wheel and edge wheel structure provided by the embodiment of the application is as follows:
when the sea water level rises to be level with the high level of the reservoir, the control gate 330 is opened to enable the sea water to enter the reservoir 300 through the water flow channel 320 on the dam 310, when the water flow passes through the water flow channel 320, the chain-driven edge wheel ratchet transmission mechanism 200 is firstly driven, the water flow impacts and pushes the blades 212 arranged on the inner wall of the edge wheel 210 of the edge wheel ratchet transmission mechanism 200, the edge wheel 210 rotates clockwise to convert tidal energy into mechanical energy, the edge wheel 210 drives the correspondingly meshed connecting gear 220 to rotate anticlockwise through the first outer gear ring 213, the connecting gear 220 drives the corresponding fixed disc 241 of the pawl 240 to rotate anticlockwise through the connecting shaft 230, the tooth space 253 orientation of the ratchet 250 in the chain-driven edge wheel ratchet transmission mechanism 200 is also arranged anticlockwise, therefore, when the fixed disc 241 of the pawl 240 rotates, the ratchet 250 drives the corresponding transmission gear 110 to rotate anticlockwise through the tooth space 253 of the eight steel balls which are pressed against the corresponding tooth spaces 253 of the ratchet 250, and drives the ratchet 250 to rotate anticlockwise through the third gear ring 252 and the central shaft 130 and the generator 244 which are finally driven by the central shaft 130 and the central shaft 130.
Then, the water flow further flows along the water flow channel 320 to the edge wheel ratchet transmission mechanism 200 through the gear transmission, so as to drive the edge wheel 210 to rotate clockwise, so as to convert tidal energy into mechanical energy, the water flow impacts and pushes the blades 212 arranged on the inner wall of the edge wheel 210, so that the edge wheel 210 rotates clockwise to convert tidal energy into mechanical energy, the edge wheel 210 drives the corresponding meshed connecting gear 220 to rotate counterclockwise through the first outer gear ring 213, the connecting gear 220 drives the corresponding fixed disc 241 of the pawl 240 to rotate counterclockwise through the connecting shaft 230, the tooth grooves 253 of the ratchet wheel 250 in the gear transmission edge wheel ratchet transmission mechanism 200 are arranged clockwise, therefore, when the fixed disc 241 of the pawl 240 rotates counterclockwise, the eight steel balls 244 are compressed by the wedge 243 to retract into the corresponding grooves 242, at this time, the fixed disc 241 of the pawl 240 can not idle run and press the tooth grooves 253 end point to drive the ratchet wheel 250 to rotate counterclockwise, but the central shaft 100 and the generator 340 connected with the central shaft are driven by the edge wheel ratchet transmission mechanism 200 to rotate counterclockwise, so that the central shaft 100 will drive the edge wheel ratchet transmission gear transmission mechanism 110 driving the ratchet transmission gear 200 to rotate counterclockwise.
When the seawater is detected to be level with the low seawater level, the control gate 330 is automatically closed.
When the tide comes back, the water level difference between the water level in the reservoir 300 and the seawater is continuously increased, when the minimum water head of the turbine for power generation is reached, the control gate 330 is automatically opened, so that the water in the reservoir 300 enters the sea through the water flow channel 320, the water flow firstly passes through the edge wheel ratchet transmission mechanism 200 in gear transmission, drives the edge wheel 210 of the edge wheel ratchet transmission mechanism 200 in gear transmission to rotate anticlockwise to convert tidal energy into mechanical energy, the edge wheel 210 drives the corresponding meshed connecting gear 220 to rotate clockwise through the first outer gear ring 213, the connecting gear 220 drives the corresponding fixed disc 241 of the pawl 240 to rotate clockwise through the connecting shaft 230, because the tooth socket 253 of the ratchet 250 in the edge wheel ratchet transmission mechanism 200 in gear transmission is arranged clockwise, the fixed disc 241 of the pawl 240 drives the eight steel balls 244 to press against the end point of the tooth socket 253 of the corresponding ratchet 250 to rotate clockwise, the ratchet 250 drives the meshed transmission gear 110 to rotate anticlockwise through the second outer gear ring 252 of the outer wall, and finally drives the central shaft 100 and the generator 340 connected with the central shaft through the transmission gear 110 to rotate anticlockwise to generate power.
Then, water flows through the chain-driven edge wheel ratchet transmission mechanism 200, the water impacts and pushes the edge wheel 210 of the edge wheel ratchet transmission mechanism 200 to rotate counterclockwise, the edge wheel 210 drives the correspondingly meshed connecting gear 220 to rotate clockwise through the first outer gear ring 213, the connecting gear 220 drives the corresponding fixed disk 241 of the pawl 240 to rotate clockwise through the connecting shaft 230, and the tooth grooves 253 of the ratchet wheels 250 in the chain-driven edge wheel ratchet transmission mechanism 200 are arranged counterclockwise.
Therefore, when the fixing plate 241 of the pawl 240 rotates clockwise, the eight steel balls 244 are pressed by the wedge 243 to compress the corresponding springs 245 and retract into the corresponding grooves 242, at this time, the fixing plate 241 of the pawl 240 idles and cannot press the end point of the tooth space 253 through the steel balls 244 to drive the ratchet wheel 250 to rotate clockwise, but the central shaft 100 and the generator 340 connected thereto are driven by the edge wheel ratchet transmission mechanism 200 driven by the gear to rotate counterclockwise, so the central shaft 100 drives the transmission gear 110 of the edge wheel ratchet transmission mechanism 200 driven by the chain to rotate counterclockwise, and further drives the ratchet wheel 250 of the edge wheel ratchet transmission mechanism 200 driven by the gear to rotate counterclockwise through the transmission chain 120.
When the seawater level is equal to the minimum generating head, the power generation is stopped, and the control gate 330 is automatically closed.
