[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Common wind turbines are mainly turbine wind power generation equipment. Among turbine wind power generation equipment, twin-turbine wind power generation equipment generates electricity through the rotation of two worm gear turbines, which greatly improves the efficiency of wind power generation.

[0003] After searching, the patent with publication number CN212130670U discloses "a dual-turbine wind power generation device". This patent mainly installs two sets of turbines on the main shaft and fixes the two ends of the main shaft so that the two sets of turbines rotate on the main shaft to generate electricity and improve the stability of the wind turbine.

[0004] However, since the wind direction is intersected with the rotation direction of the turbine, the turbine is directly subjected to the wind during rotation, making it very easy for the turbine to be damaged during use. In this patent, the two ends of the main shaft are fixed. When the turbine needs to be replaced, the two turbines together with the main shaft must be removed from the entire device, and then the nut used to limit the movement of the turbine must be unscrewed before the turbine can be replaced. This is time-consuming, labor-intensive, and inconvenient to replace. Summary of the invention

[0005] The utility model aims to provide a twin-turbine wind power generation device, which can separate the connection block from the connection seat by separating the limit rod from the connection block, that is, separate the connection rod from the turbine, so that the turbine can be replaced quickly and conveniently, saving time and effort.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a dual-turbine wind power generation device, including a main shaft, a connecting assembly is installed on the surface of the main shaft, the connecting assembly includes a rotating plate, the interior of the rotating plate is rotatably connected to the outer surface of the main shaft, the side surface of the rotating plate is movably connected with a connecting rod, the lower surface of the connecting rod is fixedly connected with a fixed block, the interior of the fixed block is movably connected with a limiting rod, one end of the limiting rod is fixedly connected with a pull handle, the side surface of the fixed block is fixedly connected with a spring, the outer surface of the limiting rod is fixedly connected with a fixing plate, the side surface of the fixing plate is fixedly connected to one end of the spring, the lower surface of the connecting rod is fixedly connected with a connecting block, the outer surface of the main shaft is rotatably connected with a turbine, and the side surface of the turbine is fixedly connected with a connecting seat.

[0007] Optionally, the lower end of the connecting block extends through the interior of the connecting seat to below the connecting seat, and the lower end of the connecting block is movably connected to the other end of the limiting rod.

[0008] Optionally, there are two groups of the connecting components, the two groups of the connecting components are mirror-symmetrical along the vertical center axis of the main shaft, and the rotation directions of the two turbines are opposite.

When the turbine needs to be replaced, the pull handle is pulled so that the pull handle drives the limit rod to move backward and separate from the connection block, thereby releasing the blocking of the connection block, and the connection rod is pushed upward to rotate the connection rod, thereby driving the connection block to separate from the connection seat. The operation is performed sequentially to separate the turbine from the utility model, and the turbine can be replaced. The new turbine is connected to the main shaft, and the connection rod is rotated downward to insert the connection block into the connection seat.
