With reference to fig. 1 to 5, a generator 3 group comprises: a box body 1; an engine 2 installed in the case 1; the generator 3 is arranged in the box body 1; wherein, the stator 31 of the generator 3 is connected with a wire harness structure 4 at one end close to the engine 2.

The external wiring harness on the generator 3 is usually led out from the bottom of the generator, namely, one end (point B in fig. 1 and fig. 2) of the stator 31 far away from the engine 2 is led out, and then the external wiring harness is drawn to one side of the engine 2 around the outer wall of the generator 3 to be merged with the wiring harness led out from the engine 2; the wiring harness is led out from one end, close to the engine 2, of the stator 31, the outer side of the outer wall of the generator 3 is free of the wiring harness, the structure is simplified, and the wiring harness is saved.

Further, the generator 3 includes: a power generation case 34; a stator 31 mounted in the power generation case 34; a rotor 32 coaxially connected with a rotation shaft 33; wherein, the rotating shaft 33 is connected with the engine 2; the wire harness structure 4 is provided with a wire harness ring 41, an external wire and a protection tube 42; the wire harness ring 41 is coaxially connected with one end of the stator 31 facing the engine 2; the power generation shell 34 is provided with an external connection hole 35; the external wire passes through the external connection hole 35 and then is connected with the wire harness ring 41; the protection tube 42 is sleeved outside the external connection line and clamped in the hole of the external connection hole 35.

Compared with the traditional wire outgoing from the bottom of the generator 3, the wire harness ring 41 is directly connected with the wire on the stator 31, and a wire row needs to be additionally arranged at the bottom of the generator 3; the bottom of the device is not provided with wires, so that a wire row is not needed, and the wire harness ring 41 has a simple structure and low manufacturing cost.

Further, the bidirectional suction mechanism 5 is connected between the engine 2 and the generator 3; the bidirectional suction mechanism 5 includes: a bidirectional air draft disc 51 sleeved on the rotating shaft 33; an air draft shell 52 sleeved on the bidirectional air draft disc 51;

the draft housing 52 includes a diversion outlet 521 and two suction openings 522 that are concentric with each other, and the draft housing 52 guides the airflow drawn from both sides by the bidirectional suction plate 51 out of the diversion outlet 521.

The air flow from the diversion outlet 521 enters the air duct and is discharged out of the cabinet 1. The engine 2 rotates to drive the rotating shaft to rotate, and then drives the bidirectional air suction disc 51 to rotate, the bidirectional air suction disc 51 sucks air from the air suction ports 522 on two sides, and simultaneously transports the sucked air to the diversion outlet 521 to blow out, so that the generator 3 and the engine 2 are cooled by heat dissipation at the same time. The two suction ports 522 face the generator 3 and the engine 2 on the same side. Compared with the arrangement of the cooling devices of the generator 3 and the engine 2 respectively, the arrangement of the bidirectional air suction disc 51 is simplified in structure, and only one air duct needs to be arranged behind the bidirectional air suction disc.

Further, the air draft shell 52 is connected with and communicated with the inside; a filter 53 is provided in the suction opening 522 of the suction casing 52 on the side facing the engine 2.

When the airflow is sucked by the bidirectional suction disc 51, the airflow flows out from one end of the generator 3 to the bidirectional suction disc through the inside of the generator 3, and the filter screen 53 is also arranged at the air inlet end of the generator 3. And the suction opening 522 of the suction casing 52 facing the engine 2 is provided with a filter screen to prevent impurities from entering the suction casing 52 and then entering the generator 3.

Further, the bidirectional louver 51 includes: a tray body 511 fitted around the rotary shaft 33; two sleeves 512 are arranged and coaxially connected to two sides of the tray body 511; a plurality of suction fan blades 513 uniformly distributed along the circumference of both sides of the tray body 511; wherein the suction vane is connected to the disk 511 and is inclined toward the middle of the disk 511.

The inclination directions of the suction fan blades 513 on the two sides of the tray body 511 are the same, the suction fan blades 513 drive the airflow along with the rotation of the tray body 511, the two-way air draft tray 51 is covered by the air draft casing 52, and the air flows out when the suction fan blades 513 pass through the air guide outlet 521 of the air draft casing 52. Because the suction fan blades 513 on the two sides of the tray body 511 have the same inclination angle, that is, the air flow is discharged in the same direction, the hot air on the two sides can be guided out by arranging the flow guide outlet 521, and the structure is simplified.

Further, the cross section of the suction fan blades 513 is an arc-shaped strip.

The middle of two adjacent suction fan blades 513 is a curved rectangular space due to the shape of the suction fan blades 513, and compared with the rectangular space, the volume is larger, and more air flows can be accommodated.

Further, a plurality of reinforcing ribs 514 are also included; two ends of the reinforcing rib 514 are respectively connected with the outer walls of the suction fan blades 513 and the sleeve 512; the ribs 514 are arranged in a curved manner and are curved in the opposite direction to the direction of curvature of the suction fan blades 513. The reinforcing ribs 514 may be provided for each of the suction fan blades 513, or may be provided at intervals of several suction fan blades 513.

As the air between the suction fan blades 513 enters the diversion outlet 521 of the draft housing 52, more air flows enter the position of the stiffener 514, and as the disc 511 rotates, the air flow bent out of the stiffener 514 flows along the shape of the inflow channel and flows into the space formed by the suction fan blade 513 connected with the stiffener and the adjacent suction fan blade 513. The reinforcing ribs 514 not only can reinforce the structural strength of the tray body 511, but also can play a role in guiding flow.
