Description

Steering device operating mechanism for hydropower station

Technical Field

The invention relates to the technical field of impulse turbine power generation, in particular to a steering gear operating mechanism applied to a hydropower station.

Background

The impulse turbine is a hydraulic prime mover which uses a special water guide mechanism to lead out free jet flow with kinetic energy, and the free jet flow is rushed to a runner bucket to enable the runner to rotate to do work, thereby completing the conversion of water energy into mechanical energy.

The deflector is a component for blocking jet flow in the water bucket turbine to redirect the jet flow. When the load is suddenly and greatly reduced, the speed regulator makes the deflector cut the jet flow, so that part of the jet flow and all the jet flow are not flushed on the water bucket any more, the water turbine is prevented from flying away, the speed regulator can slowly close the spray needle, so that the generation of larger water hammer pressure is avoided, the inner wall of the pipeline generates a water hammer effect, and the pipeline is damaged. The deflector has the main function of avoiding the negative effect caused by the too high water flow speed.

The water hammer effect means that the inner wall of the water pipe is smooth and the water flow is free. When the open valve is suddenly closed, the water flow will generate a pressure against the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow rapidly reaches the maximum under the action of inertia and generates a destructive action, namely a 'water hammer effect', namely a positive water hammer in the water conservancy. This factor is considered in the construction of hydraulic pipelines. Conversely, when the closed valve is suddenly opened, a water hammer, called a negative water hammer, is also generated, and a certain destructive force is also generated, but the water hammer is not large.

Most of the existing deflector operating mechanisms of impulse turbines only use an air cylinder or a motor to drive a water baffle to be blocked at the front end of a water outlet of a water pipe, and the mode is low in efficiency and cannot be used under the condition of power failure.

Embodiment III:

Referring to fig. 11, in this embodiment, other structures are unchanged, and further, a rotating handle 51 is fixedly connected to the upper surface of the bevel gear 3.

The integral resetting device is convenient to reset, the bevel gear I3 is reversely rotated through the rotating handle 51 to drive the bevel gear II 8 to reversely rotate, so that the rotating rod I10 is driven to reversely rotate, and the integral resetting device is reversely driven to reset.

The working principle of the first embodiment of the application is as follows: the water is ejected from the water outlet of the water pipe 11, and the nozzle 23 of the rotating seat 17 is used for impacting the runner bucket of the water turbine, so that the runner rotates to do work, and the water energy is converted into mechanical energy and then the mechanical energy is converted into electric energy.

Meanwhile, water flows into the shunt tube 2 and flows into the water barrel 1, so that the recoil bucket 27 is pushed by the impact force of the water flow to drive the rotary drum 26 to rotate in the water barrel 1 through the second rotating shaft 28, the rotation of the second rotating shaft 28 drives the fixed barrel 30 to drive the sliding rod I44 to rotate by taking the second rotating shaft 28 as a circle center, the sliding rod I44 drives the friction block 31 to rotate by taking the second rotating shaft 28 as a circle center, and the pushing block 33 is abutted against one end, close to the second rotating shaft 28, of the fixed barrel 30 under the action of the elastic force of the pushing spring 32 due to the fact that the rotating speed is low at the moment, so that the pushing block 33 can pull the sliding rod I44 to pull the friction block 31 to be prevented from moving in the direction away from the second rotating shaft 28. With the rotation of the recoil bucket 27, when the recoil bucket rotates to the position of the water outlet 29, water flows into and out of the water bucket 7 from the water outlet 29 of the water drum 1, and finally flows into the tail sump of the generator.

In the traditional device, a detection device is used for detecting the pressure of water, when the rising of the water pressure is detected, a pressure signal is transmitted to a numerical control center, and then a motor or an air cylinder is controlled by the numerical control center to push a deflector to work so as to block a water pipe, so that the deflector does not spray water to a runner bucket. According to the invention, the water pressure is not required to be detected, when the water pressure is increased, the friction block 31 can rotate faster, and the friction block 31 can drive the centrifugal disk 5 to drive the bevel gear II 8 to rotate, so that the deflector is driven to work, and the water outlet of the water pipe 11 is not sprayed onto the rotating wheel water bucket any more. The invention not only does not need a device for detecting water pressure, but also converts excessive water pressure into power to drive the steering gear to work. The side effect of too fast water flow is converted into a beneficial function. Compared with the traditional device, the device greatly reduces the use cost, and can automatically drive the deflector to work when the water pressure is overlarge. Moreover, the work can be realized without power equipment, and various emergency situations can be better adapted.

In addition, compared with the traditional device, the device cuts into the water flow from the direction perpendicular to the water flow injection through the water folding plate 22 to realize the interception, and the impact force of the received water flow is smaller. Compared with the traditional device, when the device adopts the arc-shaped water bucket to rotate and connect in front of the water pipe water outlet, when the device intercepts, the cylinder is adopted to push the arc-shaped water bucket to rotate in front of the water pipe water outlet to realize interception, but the impact force of high-pressure water flow to the diverter is overlarge, so that the device can not realize interception rapidly, and the diverter is possibly broken by overlarge water pressure.

When the first rotating rod 10 rotates to drive the third gear 19 to rotate so as to realize the shutoff operation of the deflector, the first gear 13 is driven to rotate by the worm 12, the first gear 13 rotates to drive the second gear 14 to rotate, the second gear 14 drives the second rotating rod 24 to rotate, the second rotating rod 24 rotates to drive the third bevel gear 36 through the fourth bevel gear 37, the third bevel gear 36 rotates to drive the spline 35 to rotate so as to drive the threaded rod 34 to rotate, and the threaded rod 34 is in threaded connection with the limiting plate 39, the rotation of the threaded rod 34 can push the spray needle 40 to move towards the direction of the rotating seat 17, so that the water outlet of the water pipe 11 is slowly blocked, the water yield of the water pipe 11 is slowly reduced, and finally the water pipe is closed. Thereby avoiding the occurrence of water hammer effect and better protecting the pipeline. When the threaded rod 34 drives the spray needle 40 to move to close the water pipe 11, the stop lever 52 is pulled to move until the stop lever 52 blocks the shunt pipe 2 at one end of the water pipe 11.

In the traditional device, after the steering device is closed, the work of the spray needle is slowly regulated by the speed regulating equipment to realize the water outlet of the closed pipeline. The invention uses the power generated when the water pressure is too high to drive the needle 40 to drive the module to work, and the use cost is lower. The function of automatically adjusting the operation of the needle 40 can be realized with the increase of the water pressure.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
