Problems solved by technology

However, during the operation of the water turbine, due to the change of the water flow velocity, the rotation speed of the shaft fluctuates greatly, and the stability is poor, which is not conducive to use.
[0003] Chinese patent (notification number: CN107816407A) discloses an anti-overload hydropower generation device, including an anti-overload detection box, an electric valve, a water turbine, a base, a connecting shaft, and a generator. An electric valve is arranged above the water turbine, and the electric valve passes through the flange. It is fixedly connected with the water turbine, the bottom of the water turbine is fixedly connected with the base through bolts, the output shaft of the water turbine is connected with the connecting shaft, and the connecting shaft is connected with the generator. device, connecting shaft gear, connecting shaft supporting frame, and a connecting shaft supporting frame is installed inside the casing of the detection box. This device controls the position of the electric valve through the size of the fan blowing, thereby controlling the rotating speed of the rotating shaft, but the structure of the device is relatively complicated. There are many electrical connections, which are prone to electric shock and cause damage to the device. It directly controls the rotating shaft in high-speed rotation, which is easy to wear or even damage the device

Embodiment 1

[0024] see figure 1 , a water turbine capable of stabilizing the rotational speed, comprising a base 1 and a generator 2, the top of the base 1 is fixedly connected to a fixed seat 25, the fixed seat 25 is used to place a water receiving chamber 22, and the input shaft of the generator 2 is fixedly connected to a main shaft 3. The outer side of the main shaft 3 is fixedly connected with the fixed block 4. The fixed block 4 rotates with the main shaft 3, but will not slide on the main shaft 3. The right side of the fixed block 4 is fixedly connected with the first contact sensor 5. When the first contact sensor 5 is triggered , control the rotation of the servo motor 17, so that the rotating piece 19 turns to the vertical position, the fixed block 4 is coaxially connected with the slider 6, and the slider 6 can slide between the first contact sensor 5 and the sleeve 13, and the outer side of the slider 6 The first connecting seat 7 is fixedly connected, the first connecting sea...

Embodiment 2

[0027] see image 3 , this embodiment is improved on the basis of Embodiment 1, the bottom of the fixed plate 16 is fixedly connected to the support rod 28, the bottom of the support rod 28 is fixedly connected to the outer wall of the water receiving chamber 22, the cross section of the support rod 28 and the fixed plate 16 is triangular, Thereby, the effect of stabilizing the fixing plate 16 is played to prevent the fixing plate 16 from falling off due to external impact.

[0028] In the present invention, when in use, the water flow flows in from the water inlet pipe 21 and enters the water receiving chamber 22, and the water flow falls from a height, carrying gravitational potential energy to impact the blade 24, causing the turntable 3 to rotate, thereby driving the main shaft 3 to rotate, and transmitting the mechanical energy to the generator 2, to make the generator work; when the water flow is too fast, it will cause the speed of the turntable 23 to increase, so that ...

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to a water turbine capable of stabilizing the rotating speed. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. However, during the operation of the water turbine, due to the change of the flow rate of the water flow, the rotation speed of the rotating shaft fluctuates greatly, and the stability is poor, which is not conducive to use. [0003] Chinese patent (notification number: CN107816407A) discloses an anti-overload hydr...
