The two square tubes 131 are respectively sleeved on the upper connecting rod 43 and the lower connecting rod 44, and the square tubes 131 are horizontally and fixedly connected to the fixing column 1 through the second fixing rod 13.
Preferably, the cross section of the guide block 42 is Y-shaped, the guide block 42 includes a straight portion 421 and two inclined portions 422, the straight portion 421 is parallel to the axial direction of the water inlet pipe 5, and the included angle between the two inclined portions 422 is consistent with the orientation of the water outlet pipe 6.
When the water flow direction and the straight part of the guide block 42 form an included angle, the water flow impacts on the straight part of the guide block 42, a lateral thrust is given to the straight part 421, the straight part 421 and the two mounting boxes 2 are driven to rotate, when the straight part 421 rotates to be parallel to the water flow direction, the straight part 421 is not subjected to the lateral thrust, and the two mounting boxes 2 stop rotating, at the moment, the axial direction of the water inlet pipe 5 is consistent with the water flow direction, the water quantity entering the water inlet pipe 5 is improved, and the sliding distance of the sleeve 73 on the sliding rod 7 is increased; in addition, when the guide block 42 rotates, since the cross section of the guide block 42 is Y-shaped, after the rotation of the guide block 42 is stopped, one end of the straight part 421 away from the inclined part 422 is always opposite to the water flow direction, so that the water flow is ensured to flow in from the water inlet pipe 5 only and then flow out from the water outlet pipe 6, and the power generation efficiency is improved; in addition, because the mounting boxes 2, the upper connecting rod 43 and the lower connecting rod 44 can rotate relatively, when the guide block 42 drives the two mounting boxes 2 to rotate, the upper connecting rod 43 and the lower connecting rod 44 remain relatively static, so that the chain 114 is prevented from twisting, and the normal rotation of the chain 114 is prevented from being influenced.
Specifically, a first generator 117 is disposed on the upper side of the upper platform 11, and an input shaft of the first generator 117 is fixedly connected to the second sprocket 113.
When the floating block 3 floats up and down along with the waves, the chain 114 is driven to rotate, the chain 114 drives the second chain wheel 113 to rotate, the first generator 117 generates electricity, and the wave energy is utilized to generate electricity, so that the device is simple and efficient.
Specifically, the top of the fixed column 1 is provided with a storage battery 116, and the first generator 117 and the two second generators 252 are electrically connected with the storage battery 116.
The electric energy generated by the first generator 117 and the two second generators 252 is converted into direct current through a rectifier, and then stored in the storage battery 116, thereby being environment-friendly.
