The working principle of the invention is as follows:
the floating principle is as follows: after the water turbine set is placed in water, the water turbine set automatically floats on the water surface under the action of buoyancy because the cavity of the main body, the upper balancer and the lower balancer are designed as cavities, the density of the cavities is less than that of the water body, and the buoyancy borne by the water turbine set is greater than that of gravity; the automatic adjustment of the position of the water turbine unit in water is finally completed through the upper balancer, the lower balancer and the upper blade function of the twisted space structure in the middle of the upper balancer and the lower balancer on the surface of the main body cavity and the adjusting systems of the upper adjusting rod, the lower adjusting rod, the sliding rod groove, the sliding groove, the upper adjusting ball and the lower adjusting ball, so that the buoyancy received by the water turbine unit is equal to the gravity of the water turbine unit, and the water turbine unit floats on the water surface;
the balance principle is as follows: when the hydraulic turbine set is just placed in a water body, the set can be placed in the water body horizontally, the water body can generate thrust to the set, and the thrust acts on the centroid to generate moment; because the internal lower gravity and the internal lower structure gravity of the main body cavity are greater than the internal upper gravity and the internal upper structure gravity of the main body cavity, the unit can generate a rotating torque under the action of the gravity, so that the hydraulic turbine unit rotates clockwise; in the rotation process of the water turbine set, thrust does not act on the centroid point and forms a certain angle with the centroid line, so that a rotation moment is generated, the water turbine set rotates clockwise around the centroid point, finally, the thrust acts on the centroid point again, the rotation moments are equal, and the water turbine set is vertically balanced in a water body under the action of gravity and buoyancy;
the rotation principle is as follows: in the upper structure, when the water turbine set is placed in a water body, the water turbine set is acted by water flow, and because the upper balancer and the lower balancer are in wing shapes, when the water flow impacts the upper surfaces of the upper balancer and the lower balancer, a great driving force is generated to drive the main body cavity to rotate; the upper blade is positioned between the upper balancer and the lower balancer, is in a twisted space structure, and can more easily drive the main cavity to rotate under the thrust action of water flow; in the lower part structure, the lower blade is a twisted space structure and is easy to rotate under the action of water flow, so that the hub, the upper shaft and the lower shaft are driven to rotate; the lower blades are installed in the opposite direction, and when the water body flows out of the upper blades, the water body just falls onto the lower blades to drive the lower blades to rotate, so that the hub, the upper shaft and the lower shaft are driven to rotate; when the water flow is higher than the surface of the lower balancer, the water body can drop rapidly, and the falling water flow just drops on the lower blades to drive the lower blades to rotate, so that the hub, the upper shaft and the lower shaft are driven to rotate;
the power generation principle is as follows: when the water turbine set is placed in water, the rotating angular speed of the upper blade is different from that of the lower blade due to the fact that the flow velocity of the free surface of the water body is different from that of the inner portion of the water body, the rotating angular speed of the upper blade is larger than that of the lower blade, the upper blade is fixed on the surface of the cavity of the main body, and the stator is located on the fixing support of the cavity of the main body, so that the stator rotates along with the cavity of the main body and the upper blade, while the rotor is located on the shaft system and rotates along with the lower blade and the hub, and due to the fact that the speed difference exists between the stator and the rotor, magnetic induction line cutting movement is conducted; the angular speed of the lower blade is smaller and smaller along with the increasing of the angular speed of the upper blade, the angular speed of the lower blade is reduced to zero within a certain time and rotates reversely, the speed difference between the upper blade and the lower blade is larger and larger, and the cutting magnetic induction line moves faster and faster; when the angular velocity of the upper blade is constant, the reverse rotation angular velocity of the lower blade is also constant, the velocity difference between the upper blade and the lower blade is also constant, and the generated current is also in a stable state; finally, the generated current is led out through the outgoing pipe;

5. A floating hydraulic turbine assembly according to claim 1, further comprising: the working principle is as follows:
the floating principle is as follows: after the water turbine set is placed in water, the water turbine set automatically floats on the water surface under the action of buoyancy because the main body cavity (18), the upper balancer (11) and the lower balancer (12) are designed as cavities, the density of the cavities is less than that of a water body, and the buoyancy borne by the water turbine set is greater than that of gravity; the automatic adjustment of the position of the water turbine set in water is finally completed through the action of an upper balancer (11) and a lower balancer (12) on the surface of a main body cavity (18) and an upper blade (19) of a twisted space structure between the upper balancer and the lower balancer as well as an adjusting system of an upper adjusting rod (1), a lower adjusting rod (2), a sliding rod groove (3), a sliding groove (8), an upper adjusting ball (9) and a lower adjusting ball (10), so that the buoyancy force borne by the water turbine set is equal to the gravity of the water turbine set, and the water turbine set floats on the water surface;
the balance principle is as follows: when the hydraulic turbine set is just placed in a water body, the set can be placed in the water body horizontally, the water body can generate thrust to the set, and the generated moment is 0 due to the effect of the thrust on the centroid; because the gravity of the lower part and the gravity of the lower structure in the main body cavity (18) are greater than the gravity of the upper part and the gravity of the upper structure in the main body cavity (18), the unit can generate a rotating moment under the action of the gravity, so that the hydraulic turbine unit rotates clockwise; in the rotation process of the water turbine set, thrust does not act on the centroid point and forms a certain angle with the centroid line, so that a rotation moment is generated, the water turbine set rotates clockwise around the centroid point, finally, the thrust acts on the centroid point again, the rotation moments are equal, and the water turbine set is vertically balanced in a water body under the action of gravity and buoyancy;
the rotation principle is as follows: in the upper structure, when the water turbine set is placed in a water body, the water turbine set is acted by water flow, as the upper balancer (11) and the lower balancer (12) are both in wing shapes, the water flow can generate great driving force when impacting the upper surfaces of the upper balancer (11) and the lower balancer (12) to drive the main body cavity (18) to rotate, when the water flow is higher than the upper surface of the upper balancer (11), the water body can rapidly fall down and fall onto the upper blades (19), however, the upper blades (19) are in twisted space structures, the water falling from the surface of the upper balancer (11) just falls onto the upper blades (19), and the relative rotation of the main body cavity (18) is accelerated; the upper blade (19) is positioned between the upper balancer (11) and the lower balancer (12) and is in a twisted space structure, and the main body cavity (18) is more easily driven to rotate under the thrust action of water flow; in the lower structure, the lower blade (36) is a twisted space structure and is easy to rotate under the action of water flow, so that the hub (40), the upper shaft (20) and the lower shaft (21) are driven to rotate; the lower blades (36) are installed in the opposite direction, when the water body flows out of the upper blades (19), the water body just falls onto the lower blades (36) to drive the lower blades (36) to rotate, so that the hub (40), the upper shaft (20) and the lower shaft (21) are driven to rotate; when the water flow is higher than the surface of the lower balancer (12), the water body can drop rapidly, and the falling water flow just drops on the lower blades (36) and drives the lower blades (36) to rotate, so that the hub (40), the upper shaft (20) and the lower shaft (21) are driven to rotate;
the power generation principle is as follows: when the water turbine set is placed in water, the rotating angular speed of the upper blade (19) is different from the rotating angular speed of the lower blade (36) due to the fact that the flow velocity of the free surface of the water body is different from the flow velocity of the inner portion of the water body, the rotating angular speed of the upper blade (19) is larger than the rotating angular speed of the lower blade (36), the upper blade (19) is fixed on the surface of the main cavity (18), and the stator (25) is located on the fixing support (23) of the main cavity (18), so that the stator (25) rotates along with the main cavity (18) and the upper blade (19), the rotor (26) is located on the shaft system and rotates along with the lower blade (36) and the hub (40), and magnetic induction line cutting movement is conducted due to the fact that the speed difference exists between the stator (25) and the rotor (26), and current is generated; as the angular speed of the upper blade (19) is larger and larger, so that the angular speed of the lower blade (36) is smaller and smaller, the angular speed of the lower blade (36) is reduced to zero and rotates reversely within a certain time, the speed difference between the upper blade (19) and the lower blade (36) is larger and larger, and the cutting magnetic induction line moves faster and faster; when the angular velocity of the upper blade (19) is constant, the reverse rotation angular velocity of the lower blade (36) is also constant, the velocity difference between the upper blade and the lower blade is also constant, and further the generated current is also in a stable state; finally, the generated current is led out through the wire outlet pipe (5);
the control principle is as follows: the lead is inserted into the traction ball (6), the hydraulic turbine set is placed into water flow through the lead, the position of the hydraulic turbine set in water is controlled, when the hydraulic turbine set does not need to work, the lead is pulled forcefully to destroy the balance of the hydraulic turbine set in water, so that the hydraulic turbine set stops working, and the purpose of controlling the hydraulic turbine set to work is achieved.
