The embodiments of the present invention are presented for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to better explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use.

如图1所示，本发明技术方案一种紧凑型高压发电机，包括动力箱2、接线盒3和发电箱1，动力箱2和接线盒3均固定在发电箱1上。发电箱1内设置有定子12、转子13、转子转轴11、发电箱前端盖15和发电箱后端盖14。动力箱2内设置有动力传动装置，动力传动装置带动转子转轴11旋转。动力箱2与发电箱1连通，且动力箱2内设置有散热装置，散热装置由动力箱2与发电箱1连通位置吸取发电箱1内空气实现对发电箱1内部进行散热。As shown in FIG. 1 , the technical solution of the present invention is a compact high-voltage generator, including a power box 2 , a junction box 3 and a generator box 1 , and the power box 2 and the junction box 3 are both fixed on the generator box 1 . The generator box 1 is provided with a stator 12 , a rotor 13 , a rotor shaft 11 , a front end cover 15 of the generator box and a rear end cover 14 of the generator box. The power box 2 is provided with a power transmission device, and the power transmission device drives the rotor shaft 11 to rotate. The power box 2 communicates with the generator box 1, and a heat sink is arranged in the power box 2. The heat sink absorbs the air in the generator box 1 from the position where the power box 2 communicates with the generator box 1 to dissipate heat inside the generator box 1.

上述技术方案中，利用发电机1上原始接线盒3端部位置，改变原发电机动力与发电机转子转轴直接连接的方式，将动力箱2安装在接线盒3端部，不增加发电机整体的高度，而降低发电机的长度，实现减小发电机体积的目的。增加动力箱2，将散热装置安装在动力箱2内，减下发电机体积，同时，在发电箱1内实现两端进风，改善冷却能力。In the above technical solution, the position of the end of the original junction box 3 on the generator 1 is used to change the direct connection between the original generator power and the rotor shaft of the generator, and the power box 2 is installed at the end of the junction box 3, without increasing the overall generator. The height of the generator is reduced, and the length of the generator is reduced to achieve the purpose of reducing the volume of the generator. The power box 2 is added, and the heat dissipation device is installed in the power box 2 to reduce the volume of the generator.

动力箱2包括动力箱本体、动力箱前端盖、动力箱后端盖、穿过动力箱前端盖和动力箱后端盖的动力转轴21以及套接在动力转轴21上的动力齿轮22，动力转轴21还套接有两背向设置的叶片23，叶片23设置在动力箱2与发电箱1连通位置。叶片23高速旋转，在两背向的叶片23之间形成负压区，实现由动力箱2与发电箱1连通对发电箱1内抽取负压，实现对发电箱1内进行风冷，免除了在发电箱1内设置冷却风机的问题，降低了发电箱1的长度，简化了发电箱1内部结构。发电箱1两端均能够进风，改善了发电箱1的风冷效果。The power box 2 includes a power box body, a power box front end cover, a power box rear end cover, a power rotating shaft 21 passing through the power box front end cover and the power box rear end cover, and a power gear 22 sleeved on the power rotating shaft 21.

The problem of arranging a cooling fan in the generator box 1 reduces the length of the generator box 1 and simplifies the internal structure of the generator box 1 . Both ends of the generator box 1 can enter air, which improves the air cooling effect of the generator box 1 .

动力箱前端盖和动力箱后端盖上均设置有第一风孔。叶片23旋转，向两端吹风，在两叶片23之间形成负压，便于对发电箱1内部进行风冷。The front end cover of the power box and the rear end cover of the power box are both provided with first air holes. The blades 23 rotate to blow air toward both ends, and a negative pressure is formed between the two blades 23, which is convenient for air cooling inside the generator box 1 .

Both the first driven gear 24 and the second driven gear 25 are placed in the generator box 1. And the second driven gear 25 is sleeved on the rotor shaft 11 . The diameters of the power gear 22 , the first driven gear 24 and the second driven gear 25 are gradually reduced to achieve an increase in the rotational linear speed, that is, an increase in the transmission power, which facilitates the realization of high-voltage power generation.

在发电箱前端盖15和发电箱后端盖14上均设置有第二风孔。即发电箱1两端均能够进风，实现风冷，提高风冷效果。发电箱1与动力箱2连接处设置有连通口4，叶片23设置在连通口4上部位置。Second air holes are provided on both the front end cover 15 of the generator box and the rear end cover 14 of the generator box.
