[0018] A water turbine box with hydraulic drive function, such as Figures 1 to 8 As shown, it includes a volute-shaped turbine housing 1, a vortex housing 2, an inlet channel 3, and an outlet channel 4. The turbine housing 1, vortex housing 2, inlet channel 3, and outlet channel 4 are integrally formed structures. The inlet channel 3 includes a main channel 3-1 and a secondary channel 3-2. The aperture of the main channel 3-1 is larger than the aperture of the secondary channel 3-2. The main channel 3-1 is connected to the outlet channel 4, and the secondary channel 3-2 is connected to the turbine housing 1. The turbine housing 1 and the vortex housing 2 are coaxial and connected. The vortex housing 2 and the outlet channel 4 are connected. Connecting; a connecting flange 5 is uniformly formed at the port of the main channel 3-1 and the secondary channel 3-2, and a connecting flange 5 is also integrally formed at the port of the outlet channel 4; a water turbine 6 is installed in the turbine chamber 1 through the turbine shaft, and the turbine shaft extends to the outside of the turbine chamber 1 as a power output shaft; a flow regulating valve plate 8 is installed in the main channel 3-1 of the inlet channel 3 through the rotatable valve shaft 7, and one end of the valve shaft 7 extends through the side wall of the main channel 3-1 to the outside of the main channel 3-1.

[0019] After the inlet channel 3 is connected to the inlet pipe via the connecting flange 5, the water flow in the inlet pipe will be split into the main channel 3-1 and the secondary channel 3-2. The water flowing into the main channel 3-1 will flow directly into the outlet channel 4, while the water flowing into the secondary channel 3-2 will enter the turbine chamber 1, first driving the water turbine 6 to rotate, then entering the vortex chamber 2, and finally flowing into the outlet channel 4, merging with the water flowing directly from the main channel 3-1 into the outlet channel 4. By rotating the valve shaft 7, the opening and closing of the flow regulating valve plate 8 can be adjusted, thereby regulating the water flow in the main channel 3-1. Therefore, with the total water flow in the connected inlet pipe remaining constant, adjusting the flow regulating valve plate 8 can indirectly regulate the water flow in the secondary channel 3-2, because the larger the water flow in the main channel 3-1, the smaller the water flow in the secondary channel 3-2, and vice versa. After the water turbine 6 is driven to rotate, it drives the turbine shaft to rotate, and the turbine shaft outputs power for use in connecting external devices.

[0020] In order to optimize the structure of the secondary flow channel 3-2 and increase the driving force of the water flow through the secondary flow channel 3-2 on the water turbine 6, the number of secondary flow channels 3-2 is designed to be 2.

[0021] In order to facilitate product assembly and maintenance, the turbine bin 1 comprises a main bin body 1-1 and a bin cover 1-2, the main bin body 1-1 and the bin cover 1-2 are fixedly connected by bolts, a turbine shaft positioning table 1-2-1 is formed in the center of the bin cover 1-2, and the turbine shaft is positioned and installed through the turbine shaft positioning table 1-2-1.

[0022] The outer end of the vortex bin 2 is open, and a sealing end cover 2-1 is fixedly connected by bolts. The purpose of this structure design is that when some minor faults occur in the product, the sealing end cover 2-1 can be opened for observation and maintenance, which is more convenient and fast.

[0023] Because the installation environment of the product is different when it is used, the installation and use of the valve shaft 7 may be affected, therefore, two valve shaft mounting holes 3-3 for mounting the valve shaft 7 are formed on the main flow channel 3-1, one of the two valve shaft mounting holes 3-3 is located at the top of the main flow channel 3-1, and the other is located at the side of the main flow channel 3-1. The two valve shaft mounting holes 3-3 are preset, so that the appropriate valve shaft mounting hole 3-3 can be selected to install the valve shaft 7 and the flow regulating valve plate 8 according to the actual situation.

[0024] The above embodiment is only used for explaining the utility model, and is not limited to the protection of the utility model, any non-substantial change on the basis of the essential scheme of the utility model should fall within the protection scope of the utility model.
