In the direction of 11), such a turbine device is referred to as a "diameter-axial flow" type turbine device. The present invention prefers a "diameter-axial flow" type turbine device because of its high aerodynamic efficiency, which enables more gas flow energy to be converted into mechanical energy.
作为更优的实施方式， 所述涡轮壳 10的气流出口 10b截面面积与所述 离心风机蜗壳的气流出口 50a截面面积之比大于 1.4。 这样的设计是为了降 低气流从涡轮壳 10的气流出口 10b最终排入大气的流速， 避免或减少高速 气流对清扫作业的干扰。  As a more preferred embodiment, the ratio of the cross-sectional area of the airflow outlet 10b of the turbine casing 10 to the cross-sectional area of the airflow outlet 50a of the centrifugal fan volute is greater than 1.4. This design is to reduce the flow rate of airflow from the air outlet 10b of the turbine casing 10 to the atmosphere, and to avoid or reduce the interference of the high-speed airflow to the cleaning operation.
作为可替代的方案， 所述涡轮壳 10的气流进口 10a也可以位于涡轮的 轴向上， 而所述涡轮壳 10的气流出口 10b位于涡轮的轴向上并与气流进口 10a相对。这种涡轮装置称为"轴流"式涡轮装置，具有加工方便、重量较轻， 径向尺寸较小的优点。  As an alternative, the gas flow inlet 10a of the turbine casing 10 may also be located in the axial direction of the turbine, and the gas flow outlet 10b of the turbine casing 10 is located in the axial direction of the turbine and opposed to the gas flow inlet 10a. This type of turbine device is called an "axial flow" type turbine device and has the advantages of convenient processing, light weight, and small radial size.
在图 2和图 3所示的实施例中， 所述涡轮壳 10的气流出口 10b朝向扫 盘 30所在位置的相反一侧， 而不面向扫路车扫盘 30的工作清扫面 （即扫 盘 30工作时扫盘刷丝 30a对地面的清扫工作范围）， 所述动力输出轴 11与 所述离心风机的轮轴 51垂直， 涡轮壳 10和离心风机的蜗壳连接呈 L形， 因此可称之为 L形布局。这种布局方式中，涡轮壳 10的气流出口 10b朝上， 气流流出几乎不会干扰扫路车扫盘刷丝 30a对地面的清扫作业； 并且， 从 离心风机排出的高速气流在流经涡轮装置后流速已经大幅下降， 在从涡轮 壳 10的气流出口 10b排出时， 所受阻力也已经大幅下降。 In the embodiment shown in FIGS. 2 and 3, the airflow outlet 10b of the turbine casing 10 faces the opposite side of the position where the sweeping disk 30 is located, and does not face the working cleaning surface of the sweeping wheel 30 (ie, the sweeping disk). 30 is the cleaning working range of the sweeping wire 30a to the ground when working, the power output shaft 11 is perpendicular to the axle 51 of the centrifugal fan, and the volute of the turbine casing 10 and the centrifugal fan is L-shaped. Therefore, it can be called an L-shaped layout. In this arrangement, the airflow outlet 10b of the turbine casing 10 faces upward, and the airflow outflow hardly interferes with the cleaning operation of the road sweeping brush wire 30a on the ground; and the high-speed airflow discharged from the centrifugal fan flows through the turbine device. The post-flow rate has been greatly reduced, and the resistance has also been greatly reduced when discharged from the air outlet 10b of the turbine casing 10.
在图 4和图 5所示的实施例中， 扫盘 30靠近所述离心风机 50和涡轮 装置， 且位于离心风机 50和涡轮装置的一侧， 所述气流出口 10b朝向垂直 于第一侧的方向， 因此所述涡轮壳 10的气流出口 10b同样不面向扫路车扫 盘 30的工作清扫面， 所述动力输出轴 11为空心轴， 与所述离心风机的轮 轴 51位于同一轴线上 (也可以是动力输出轴 11与离心风机的轮轴 51平行）， 涡轮壳 10和离心风机的蜗壳连接呈 N形， 因此可称之为 N形布局。 这种 布局方式中， 涡轮壳 10的气流出口 10b朝向侧面， 气流流出也不会干扰扫 路车扫盘刷丝 30a对地面的清扫作业； 并且， 如图 4所示， 当涡轮壳 10的 气流出口 10b与扫路车的辅助发动机 60位置相对时， 从涡轮壳 10的气流 出口 10b排出的气流可对辅助发动机 60进行冷却， 因此， 可对辅助发动机 60 内部结构进行改造， 这样可以进一步取消其自带的风扇， 并且节省风扇 所进一步消耗的能量， 在节约能源和成本的同时， 大大提高了扫路车的节 能环保性和经济性。  In the embodiment shown in Figures 4 and 5, the sweeping disk 30 is adjacent to the centrifugal fan 50 and the turbine device, and is located on one side of the centrifugal fan 50 and the turbine device, the airflow outlet 10b being oriented perpendicular to the first side. Therefore, the airflow outlet 10b of the turbine casing 10 is also not facing the working cleaning surface of the sweeping wheel 30, and the power output shaft 11 is a hollow shaft, which is located on the same axis as the axle 51 of the centrifugal fan (also It may be that the power output shaft 11 is parallel to the axle 51 of the centrifugal fan. The turbine casing 10 and the volute of the centrifugal fan are connected in an N shape, so it may be referred to as an N-shaped layout. In this arrangement, the air outlet 10b of the turbine casing 10 faces the side, and the airflow does not interfere with the sweeping operation of the sweeping brush wire 30a on the ground; and, as shown in FIG. 4, when the turbine casing 10 is in the airflow When the outlet 10b is opposed to the auxiliary engine 60 of the road sweeper, the airflow discharged from the air outlet 10b of the turbine casing 10 can cool the auxiliary engine 60, and therefore, the internal structure of the auxiliary engine 60 can be modified, which can further cancel the same. The built-in fan, and saves the energy consumed by the fan, saves energy and cost, and greatly improves the energy saving, environmental protection and economy of the road sweeper.
所述涡轮壳 10的气流进口 10a与所述离心风机蜗壳的气流出口 50a可 以通过螺栓固定连接， 也可以通过其他方式 （例如焊接等） 实现固定连接。  The airflow inlet 10a of the turbine casing 10 and the airflow outlet 50a of the centrifugal fan volute may be fixedly connected by bolts, or may be fixedly connected by other means such as welding or the like.
所述涡轮壳 10 的气流进口 10a端部与所述离心风机蜗壳的气流出口 50a端部之间可以通过橡胶密封垫圈 14密封， 也可以通过其他方式， 例如 胶带、 套管等实现密封。  The end of the gas flow inlet 10a of the turbine casing 10 and the end of the gas flow outlet 50a of the centrifugal fan volute may be sealed by a rubber sealing gasket 14, or may be sealed by other means such as a tape, a sleeve or the like.
为了节省工艺成本， 所述叶片 13可以采用直板型； 当然， 所述叶片 13 也可以采用翼型， 这种形状更利于气流的流动， 有利于提高气动效率。  In order to save the process cost, the blade 13 may adopt a straight plate type; of course, the blade 13 may also adopt an airfoil shape, which is more favorable for the flow of the airflow, and is advantageous for improving the aerodynamic efficiency.
