Description

Technical Field

[0001] The utility model relates to the technical field of water turbine components, in particular to a high-efficiency cooling water turbine. Background Art

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It is an important hydropower equipment and an indispensable part of the hydropower industry. In a hydropower station, water from the upstream reservoir is led to the water turbine through a water diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tailwater pipe. The higher the water head and the greater the flow rate, the greater the output power of the water turbine.

[0003] When the existing water turbine is working, its driving shaft is rotatably connected with the bearing seat through the support bearing. When the impeller drives the driving shaft to run at high speed for a long time, the support bearing itself will generate high temperature due to friction and other reasons. In severe cases, the support bearing will be damaged. For this reason, we propose a high-efficiency cooling water turbine. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a high-efficiency cooling water turbine. It has the following beneficial effects:

[0014] (1) This is a high-efficiency cooling type water turbine. In this article, the drive shaft is connected and matched with the rotation support in the inner support inside the bearing seat through the support bearing, and the inner outlet of the bearing seat is sealed through the outer seal of the drive shaft. The installation groove is filled with a coolant medium through the sealed outer seal. The coolant directly soaks and wraps the support bearing to cool it down. The bearing seat is extended to the inside of the water pipe. In this way, the water source inside the water pipe can soak and wrap the outside of the bearing seat during transportation, and the support bearing inside the bearing seat is cooled for a second time, thereby achieving the effect of improving the heat dissipation of the support bearing itself and extending the operating time of the support bearing.

[0015] (2) In this high-efficiency cooling turbine, when the water source inside the water pipe flows and contacts and impacts the guide cover, the guide cover can drive the built-in piston inside the installation groove to push horizontally through the connecting shaft, and the support spring can make the built-in piston reciprocate under the squeezing of the built-in piston. At this time, the coolant inside the installation groove can flow left and right through the guide groove inside the inner support under the reciprocating push of the built-in piston, impacting and contacting the support bearing itself, increasing the fluidity of the coolant, thereby further improving the heat dissipation effect of the support bearing itself.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment: A high-efficiency cooling turbine, such as Figure 1-Figure 5 As shown, it includes a water pipe 1 and a bearing seat 2, the bearing seat 2 has a mounting groove 3 formed inside, and a drive shaft 4 is connected and rotated through the mounting groove 3;

[0027] The difference is that an inner support 5 is installed on the inner side of the bearing seat 2, and the outer periphery of the driving shaft 4 is rotatably connected to the inner side of the inner support 5 through a supporting bearing 6. The outer rotating sleeve of the driving shaft 4 is provided with an outer sealing member 7. The mounting groove 3 inside the bearing seat 2 is sealed and stored with coolant for efficiently cooling the supporting bearing 6 through the outer sealing member 7. The outer periphery of the outer sealing member 7 is sealed and connected to the inner side of the bearing seat 2 through a sealing gasket 8. A through hole 9 penetrating the mounting groove 3 is opened on one side of the bearing seat 2. A connecting shaft 10 is arranged inside the through hole 9. The outer periphery of the connecting shaft 10 is sealed and matched with the inner side of the through hole 9 through a sealing gasket 11. The outer sleeve of the driving shaft 4 is provided with a built-in piston 12. One end of the connecting shaft 10 is supported and connected to the built-in piston 12. The other end of the connecting shaft 10 is provided with a guide cover 13 sleeved on the outside of the driving shaft 4. One end of the built-in piston 12 is provided with a support spring 14 supported and connected to the inner support 5.

[0028] Furthermore, the coolant inside the bearing seat 2 wraps around the support bearing 6 outside the drive shaft 4 to dissipate heat.

[0029] Furthermore, the bearing seat 2 is extended into the water pipe 1 and is located inside the water pipe 1 to cooperate with the water source to be wrapped in a secondary cooling state.

[0030] Furthermore, the deflector 13 is an arc-shaped deflector structure. When the deflector 13 is impacted by the water source, the deflector 13 drives the built-in piston 12 inside the installation groove 3 through the connecting shaft 10 to be in a horizontal reciprocating pushing state.

[0031] Furthermore, a guide groove 15 is opened inside the inner support 5, and both ends of the guide groove 15 are arc-shaped grooves. When the built-in piston 12 is pushed horizontally back and forth, the coolant inside the installation groove 3 is connected and guided and transported through the guide groove 15 inside the inner support 5.

[0032] The working principle of this utility model:

[0033] The drive shaft 4 is rotatably supported and connected with the inner support 5 inside the bearing seat 2 through the support bearing 6, and the inner outlet of the bearing seat 2 is sealed by the outer seal 7 outside the drive shaft 4, and the installation groove 3 stores a coolant medium through the sealed outer seal 7. The coolant directly soaks and wraps the support bearing 6 to cool it down, and the bearing seat 2 extends to the inside of the water pipe 1, so that the water source inside the water pipe 1 can be soaked and wrapped with the outside of the bearing seat 2 during transportation, and the support bearing 6 inside the bearing seat 2 is cooled for a second time, thereby improving the heat dissipation of the support bearing 6 itself. To extend the operation time of the support bearing 6, when the water source inside the water pipe 1 flows and contacts and impacts the deflector 13, the deflector 13 can drive the built-in piston 12 inside the mounting groove 3 to be pushed horizontally through the connecting shaft 10, and the support spring 14 can make the built-in piston 12 reciprocate under the squeezing of the built-in piston 12. At this time, the coolant inside the mounting groove 3 can be reciprocated and flowed left and right through the deflector groove 15 inside the inner support 5 under the reciprocating push of the built-in piston 12, impacting and contacting the support bearing 6 itself, increasing the fluidity of the coolant, and further improving the heat dissipation effect of the support bearing 6 itself.
