The first wheel 2 generally has a larger radius of rotation and therefore a larger torque but a lower rotational speed.
The second rotating wheel 3 comprises a second wheel body 31 and a second rotating drum 32, the second rotating wheel 3 is arranged in the second cavity 102, one end of the second rotating drum 32 is arranged on the second rotating wheel 3 and communicated with the second rotating wheel 3, the other end of the second rotating drum 32 is inserted into the first cavity 101 and coaxially connected with the first rotating drum 22, and the second rotating drum 32 is communicated with the first rotating drum 22. The second runner 3 has a smaller radius of rotation relative to the first runner 2, and thus has a smaller torque but a higher rotational speed.
One end of the main shaft 4 is inserted into the second cavity 102 and is coaxially connected with the second wheel body 31, the other end of the main shaft 4 extends away from the direction of the shell 1, and the first wheel body 21, the first rotary drum 22, the second wheel body 31, the second rotary drum 32 and the main shaft 4 can coaxially and synchronously rotate.
By adopting the technical scheme, as the two rotating wheels synchronously rotate and are simultaneously connected with the main shaft 4 in a coaxial way, high rotating speed and high torque can be simultaneously provided for the main shaft 4.
However, in a fire-fighting environment, the hydraulic output condition is generally complex, so that the hydraulic output efficiency is high or low, and a stable level is difficult to maintain, so that if a single device is adopted, the stable hydraulic output effect is difficult to ensure, and therefore, an additional device is usually externally connected to the water turbine to ensure the stable hydraulic output; the inventor has made a great deal of research on the problem, and found that the size of the stressed surface of the rotating wheel subjected to hydraulic impact can be effectively adapted to different hydraulic output environments, so that a stable hydraulic output effect is obtained, and the invention designs a second embodiment.

Preferably, each synchronizing assembly 7 is disposed between the ring 5 and each rotating shaft 3122 in a one-to-one correspondence, and makes each rotating shaft 3122 rotate synchronously with the rotation of the ring 5, so that each vane 312 can deflect synchronously with the same deflection angle.
Specifically, as shown in fig. 1, in conjunction with fig. 6, the synchronizing assembly 7 includes a first rocker arm 71 and a second rocker arm 72; one end of the first rocker arm 71 is hinged with the penetrating end of the rotating shaft 3122, and the other end of the first rocker arm 71 extends towards the ring body 5; one end of the second rocker arm 72 is hinged with the ring body 5, and the other end of the second rocker arm 72 is hinged with the first rocker arm 71. The ring body 5 rotates and deflects a certain angle, so that the second rocker arm 72 can push the first rocker arm 71 to rotate relative to the wheel shell 311, thereby rotating the rotating shaft 3122, further realizing that the vane 3121 deflects relative to the wheel shell 311, and changing the bearing area of the straight hydraulic impact of the vane 3121.
As an alternative embodiment, the synchronizing assembly 7 further includes an elastic member 73, where the elastic member 73 is disposed between the ring body 5 and the second rocker arm 72, and the elastic member 73 plays a role of buffering, and helps the second rocker arm 72 push the first rocker arm 71 to rotate and deflect a certain angle, or helps the second rocker arm 72 pull the first rocker arm 71 to rotate and reset.
In addition, since the ring body 5 is disposed on the second rotating wheel 3 and rotates synchronously therewith, the ring body 5 can rotate relative to the second rotating wheel 3, and the normal rotation of the second rotating wheel 3 cannot be hindered, and in order to achieve this function, the present invention relates to a fourth embodiment, in which a driving force is provided to the rotation of the ring body 5 by the driving assembly 6.
As shown in fig. 1, in combination with fig. 4 and 7, the driving unit 6 includes a main gear 61, a movable gear 62, an output mechanism 63, an inner gear ring 64, and a link 65.
Wherein, cavity 401 has been seted up in the main shaft 4, and cavity 401 is close to the tip that main shaft 4 connects second runner 3, has seted up window 402 on the main shaft 4 outer wall, and window 402 communicates with cavity 401.

Working principle:
Inputting water flow fluid into the shell 1, wherein the water flow realizes zoned water inlet through the first inlet 103 and the second inlet 104 and is respectively input into the first cavity 101 and the second cavity 102, and the two water flows respectively impact the first rotating wheel 2 and the second rotating wheel 3 and enable the two water wheels to synchronously rotate through hydraulic impact; the water flows through the first wheel 21 and into the first drum 22, and the water flows through the second wheel 31 and into the second drum 32, and the two water flows are converged into one flow and discharged out of the device through the outlet 105 because the first drum 22 is communicated with the second drum 32.
Because the two rotating wheels have different rotating radiuses, when the hydraulic fluid drives the two rotating wheels to rotate respectively, the rotating wheels with smaller rotating radiuses rotate at high rotating speed but with small torque, so that the rotating speed can be provided for the main shaft 4; the rotating wheels with larger rotating radius have low rotating speed and large torque, can provide torque for the main shaft 4, and are mutually matched, so that the water turbine equipment can simultaneously have high torque and high rotating speed, and is further matched with a complex fire-fighting water supply environment.
When the rotation speed or torque of the second runner 3 needs to be adjusted, the size of the force receiving surface of the vane 312 subjected to the hydraulic impact needs to be adjusted. At this time, the output mechanism 63 is started, the main gear 61 is driven to drive the movable gear 62 to rotate, so that the annular gear 64 is driven to drive the ring body 5 to synchronously rotate; the ring body 5 deflects a certain angle, so that the second rocker arm 72 pushes the first rocker arm 71 to rotate relative to the wheel shell 311, thereby rotating the rotating shaft 3122, further realizing that the vane 3121 deflects relative to the wheel shell 311, and the stressed area of the straight hydraulic impact of the vane 3121 is changed, thereby changing the rotating speed or torque of the second rotating wheel 3.
