[0018] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0019] like Figure 1-6 As shown, the present invention provides a generator set capable of improving power generation stability, comprising a support frame 1, an engine 2, and a power generation assembly 3; the engine 2 and the power generation assembly 3 are mounted on the support frame 1; the output shaft 4 of the engine 2 is transmission-connected with the rotating shaft 5 of the rotor of the power generation assembly 3 via a shock-absorbing connector 6; the shock-absorbing connector 6 is a cylindrical structure with an opening at the front end, and a plurality of partitions 61 distributed in an annular manner are evenly arranged on the inner wall of the shock-absorbing connector 6; the end of the rotating shaft 5 of the rotor is inserted into the shock-absorbing connector 6, and the side wall of the rotating shaft 5 is evenly arranged with power transmission plates 62 distributed alternately with the partitions 61, and springs 63 are evenly connected between the partitions 61 and the power transmission plates 62. When the generator set is working, the engine 2 drives the output shaft 4 to rotate to generate mechanical energy. The output shaft 4 is connected to the rotating shaft 5 of the rotor of the generating assembly 3 through the shock-absorbing connector 6, thereby driving the rotor to rotate between the stators of the generating assembly 3, thereby generating current. When the output shaft 4 transmits kinetic energy to the rotating shaft 5, the partition 61 in the shock-absorbing connector 6 transmits the torque to the power transmission plate 62 on the rotating shaft 5 through the spring 63, thereby driving the rotating shaft 5 to rotate. The spring 63 has a shock-absorbing effect, which can reduce the vibration transmitted from the output shaft 4 to the rotating shaft 5, making the rotor rotation more stable, making the output current more stable, avoiding the use of a higher-power stabilizer to increase costs, and outputting a more stable current without using a stabilizer or using a lower-power stabilizer.

[0020] like Figure 4-5As shown, a cooling water jacket 7 is installed on the outside of the engine 2, and the water inlet and outlet of the cooling water jacket 7 are respectively connected to a water pump 72 and a cooling water tank 73 installed on the support frame 1 through a pipeline 71, and the water pump 72 is connected to the cooling water tank 73; a stirring and heat dissipation mechanism 8 is rotatably installed in the cooling water tank 73, and the stirring and heat dissipation mechanism 8 is drivingly connected to the output shaft 4 of the engine 2. When the engine 2 is working, it will generate more heat, which will increase the temperature of the engine 2. The high temperature will affect the normal operation of the engine 2. Therefore, the cooling water in the cooling water tank 73 is input into the cooling water jacket 7 through the water pump 72. The cooling water flows in the cooling water jacket 7 to take away the heat generated by the engine 2, and then flows back to the cooling water tank 73, thereby preventing the temperature of the engine 2 from continuing to rise and affecting the normal operation of the engine 2. After the cooling water flows back to the cooling water tank 73, the stirring and heat dissipation mechanism 8 in the cooling water tank 73 stirs and dissipates the cooling water, thereby reducing the water temperature of the cooling water again, and then flows back into the cooling water jacket 7 to cool the engine 2. The stirring and heat dissipation mechanism 8 is driven by the output shaft 4 of the engine 2 to rotate and stir the cooling water, so that the mechanical energy generated by the engine 2 can be used in multiple ways, thereby improving the energy utilization efficiency of the generator set and saving resources.

[0021] like Figure 4 As shown, the cooling water jacket 7 is wrapped around the outer walls of multiple cylinders of the engine 2, and an arc surface is provided inside the cooling water jacket 7 to connect with the outer wall of each cylinder. The cooling water jacket 7 is provided on the outer walls of multiple cylinders of the engine 2, and can cool down multiple cylinders at the same time, improving the cooling efficiency, and the arc surface is provided inside to contact with the outer wall of each cylinder, thereby increasing the contact area between the cooling water jacket 7 and the cylinder, thereby improving the heat transfer efficiency between the cylinder of the engine 2 and the cooling water jacket 7, so that the cooling water jacket 7 has a better cooling efficiency for the engine 2.

[0022] like Figure 5 As shown, the stirring heat dissipation mechanism 8 includes a stirring shaft 81 and a stirring rod 82, the stirring rod 82 is rotatably mounted on the side wall of the cooling water tank 73, the stirring rod 82 is evenly mounted on the side wall of the stirring shaft 81, and the stirring shaft 81 is connected to the output shaft 4 of the engine 2 through a belt drive. The output shaft 4 of the engine 2 drives the stirring shaft 81 to rotate, and the stirring shaft 81 drives the stirring rod 82 connected to the side wall to rotate to stir the cooling water in the cooling water tank 73 to cool it down, so that the cooling water flows back into the cooling water jacket 7 to cool the engine 2.

[0023] like Figure 4 As shown, a heat dissipation port 731 is provided on the top of the cooling water tank 73. The heat dissipated by the stirring and heat dissipation mechanism 8 when stirring the cooling water is discharged from the heat dissipation port 731, thereby increasing the cooling efficiency of the cooling water.

[0024] like Figure 4-6As shown, a cross mounting frame 732 is installed in the heat dissipation port 731, and a fan 9 is rotatably installed on the cross mounting frame 732. The fan 9 is connected to the end of the stirring shaft 81 through a transmission rod 10 installed on the side wall of the cooling water tank 73; the transmission rod 10 is rotatably installed on a fixed plate installed on the side wall of the cooling water tank 73 through a bearing, and the lower end is connected to the end of the stirring shaft 81 through a bevel gear, and the upper end is connected to the fan 9 through a belt drive; the top of the cooling water tank 73 is also provided with an air inlet 11. When the output shaft 4 of the engine 2 drives the stirring shaft 81 to rotate, the stirring shaft 81 drives the transmission rod 10 to rotate through the bevel gear, and the transmission rod 10 drives the fan 9 to rotate through the belt drive, thereby accelerating the heat dissipation in the cooling water tank 73 and improving the cooling efficiency of the cooling water. At the same time, an air flow is formed in the cooling water tank 73, so that the outside air is blown into the cooling water tank 73 from the air inlet 11, and then blown out from the heat dissipation port 731, taking away the heat in the cooling water tank 73, and improving the heat exchange efficiency of the cooling water.

[0025] like Figure 1 As shown, both ends of the rotating shaft 5 of the rotor of the power generation component 3 are rotatably mounted on the support rods 12 provided on the support frame 1. The rotor of the power generation component 3 rotates relative to the stator in the stator through the support of the support rods 12, thereby generating current.

[0026] Working process: When the generator set is working, the engine 2 drives the output shaft 4 to rotate to generate mechanical energy. The output shaft 4 is connected to the rotating shaft 5 of the rotor of the generating assembly 3 through the shock-absorbing connector 6, thereby driving the rotor to rotate between the stators of the generating assembly 3, thereby generating current. When the output shaft 4 transmits kinetic energy to the rotating shaft 5, the partition 61 in the shock-absorbing connector 6 transmits the torque to the power transmission plate 62 on the rotating shaft 5 through the spring 63, thereby driving the rotating shaft 5 to rotate. The spring 63 has a shock-absorbing effect, which can reduce the vibration transmitted from the output shaft 4 to the rotating shaft 5, making the rotor rotation more stable, making the output current more stable, avoiding the use of a higher-power stabilizer to increase costs, and outputting a more stable current without using a stabilizer or using a lower-power stabilizer. When the generator set is generating electricity, the cooling water in the cooling water tank 73 is input into the cooling water jacket 7 through the water pump 72. The cooling water flows in the cooling water jacket 7, takes away the heat generated by the engine 2, and then flows back to the cooling water tank 73, thereby preventing the temperature of the engine 2 from continuing to rise and affecting the normal operation of the engine 2. After the cooling water flows back to the cooling water tank 73, the output shaft 4 of the engine 2 drives the stirring shaft 81 to rotate, and the stirring shaft 81 drives the stirring rod 82 connected to the side wall to rotate to stir the cooling water in the cooling water tank 73 to cool it down, so that the cooling water flows back into the cooling water jacket 7 to cool the engine 2. The output shaft 4 of the engine 2 drives the stirring and heat dissipation mechanism 8 to rotate to stir the cooling water, so that the mechanical energy generated by the engine 2 can be used in multiple ways, thereby improving the energy utilization efficiency of the generator set and saving resources. While the output shaft 4 of the engine 2 drives the stirring shaft 81 to rotate, the stirring shaft 81 drives the transmission rod 10 to rotate through the bevel gear, and the transmission rod 10 drives the fan 9 to rotate through the belt drive, thereby accelerating the dissipation of heat in the cooling water tank 73 and improving the cooling efficiency of the cooling water. At the same time, airflow is formed in the cooling water tank 73, so that the outside air is blown into the cooling water tank 73 from the air inlet 11, and then blown out from the heat dissipation port 731, taking away the heat in the cooling water tank 73, thereby improving the heat exchange efficiency of the cooling water.
