Description

Technical Field

[0001] This utility model relates to the field of hydropower technology, specifically to a pipeline-type low-head hydropower turbine system. Background Technology

[0002] With the rapid development of intelligent management technology, the application of sensors in pipeline management has achieved remarkable progress. However, many sensor installation points cannot provide a stable power supply, leading to the emergence of numerous pipeline turbine power generation systems. Existing pipeline turbines are generally centrifugal, mixed-flow, axial-flow, and through-flow turbines. Centrifugal and mixed-flow turbines are suitable for higher water heads and high-power generation. Axial-flow turbines still generate relatively large amounts of electricity but consume a relatively high amount of water head in the pipeline. Through-flow turbines require less water head and generate less electricity, but their structure requires the motor to be located in the middle of the pipeline, placing high demands on the sealing of the motor system, resulting in longer equipment length and higher costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pipeline-type low-head hydroelectric turbine system.

[0004] The pipeline-type low-head hydroelectric turbine system of this utility model includes:

[0005] A conduit installed in a pipeline, wherein a pipeline turbine chamber is formed inside the conduit;

[0006] A turbine mechanism, which is installed inside a pipe turbine chamber, and includes a spherical turbine and a rotating main shaft;

[0007] The spherical turbine is fixedly mounted on the rotating main shaft. The spherical turbine is installed inside the pipe turbine chamber via the rotating main shaft. The rotating main shaft is rotatably connected to the top and bottom of the pipe turbine chamber via upper and lower bearings, respectively. The portion of the rotating main shaft that extends beyond the spherical turbine passes through the pipe turbine chamber and extends outward to form a drive shaft extension.

[0008] In some embodiments, the conduit is a three-way tube, which includes a main flow tube and a connection / disconnection port;

[0009] Both ends of the main pipe are connected to the existing water supply pipe. An inner cover plate is installed at the junction of the installation and disassembly port and the main pipe. The inner cover plate is arc-shaped. The inside of the tee pipe and the inner cover plate form a pipe turbine chamber.

[0010] In some embodiments, the diameter of the mounting port is larger than the diameter of the spherical turbine, the spherical turbine is mounted in the center of the main flow pipe through the central mounting port, and the rotating spindle moves through the inner cover plate.

[0011] In some embodiments, a flange is fixedly installed at the end of the mounting port, an outer cover plate is installed on the flange, the outer cover plate and the inner cover plate are integrally formed, and a mounting hole for rotating the spindle is provided in the center, the upper bearing is installed inside the mounting hole, and a sealing gasket is also provided inside the mounting hole.

[0012] In some embodiments, a guide plate is installed vertically and obliquely in the opposite direction of the rotation axis on the water inlet side where the main pipe connects to the tap water pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model installs the conduit in an existing water supply pipe, and then connects the drive shaft of the turbine mechanism to a generator or a speed-increasing device for power generation; when the water in the turbine chamber of the pipe flows, it will drive the spherical turbine to rotate around the main shaft perpendicular to the direction of the incoming flow under the action of the incoming flow, so that the pressure potential energy of the incoming medium is converted into the rotational kinetic energy of the generator rotor through the turbine mechanism to generate electricity; then the generated current is stored and used to power the sensor.

[0015] 2. This utility model improves upon the existing three-way pipe, making it easier to install and maintain. By opening the outer and inner cover plates to access the disassembly port, the spherical turbine can be easily removed, which is beneficial for installation and maintenance.

[0024] Example 1:

[0025] Please see Figure 1 The present invention relates to a pipeline-type low-head hydroelectric turbine system, comprising:

[0026] A conduit 5 is installed in a pipeline, and a pipeline turbine chamber 1 is formed inside the conduit 5;

[0027] Turbine mechanism 2 is installed inside the pipe turbine chamber 1, and includes a spherical turbine 21 and a rotating main shaft 22;

[0028] The spherical turbine 21 is fixedly mounted on the rotating main shaft 22. The spherical turbine 21 is installed inside the pipe turbine chamber 1 through the rotating main shaft 22. The rotating main shaft 22 is rotatably connected to the top and bottom of the pipe turbine chamber 1 through the upper bearing 4 and the lower bearing 3, respectively. The part of the rotating main shaft 22 that extends beyond the spherical turbine 21 passes through the pipe turbine chamber 1 and extends outward to form the drive shaft extension 23.

[0029] The engine or speed-increasing device is connected to the drive shaft extension 23 of the rotating main shaft 22.

[0030] Working principle:

[0031] The conduit 5 is installed in the existing water supply pipe, and the drive shaft extension 23 in the turbine mechanism 2 is connected to the generator or the speed-increasing device for power generation. When the water in the pipe turbine chamber 1 flows, it will drive the spherical turbine 21 to rotate around the rotating main shaft 22 vertical to the direction of the incoming flow under the action of the incoming flow. Thus, the pressure potential energy of the incoming medium is converted into the rotational kinetic energy of the generator rotor through the turbine mechanism 2 to generate electricity. The generated current is then stored and used to power the sensor.

[0032] Example 2:

[0033] Please see Figure 2 and Figure 3 As a specific improvement to Embodiment 1, unlike Embodiment 1, the conduit 5 is a three-way tube, which includes a main flow tube 51 and a disassembly port 52.

[0034] Both ends of the main pipe 51 are connected to the existing water supply pipes. An inner cover plate 6 is installed at the junction of the installation and disassembly port 52 and the main pipe 51. The inner cover plate 6 is arc-shaped. The inside of the tee pipe and the inner cover plate 6 form the pipe turbine chamber 1.

[0035] The arc radius of the inner cover plate 6 is the same as the pipe radius of the pipe turbine chamber 1, which can reduce the ineffective hydraulic loss at that location.

[0036] The diameter of the mounting port 52 is larger than the diameter of the spherical turbine 21. The spherical turbine 21 is installed in the center of the main stream pipe 51 through the mounting port 52, and the rotating main shaft 22 moves through the inner cover plate 6. A flange 10 is fixedly installed at the end of the mounting port 52. The inner diameter of the flange 10 is larger than the diameter of the spherical turbine 21. An outer cover plate 8 is installed on the flange 10. The outer cover plate 8 is integrally formed with the inner cover plate 6, and a mounting hole for rotating the main shaft 22 is provided in the center. The upper bearing 4 is installed inside the mounting hole, and a sealing gasket 9 is also provided inside the mounting hole. A sealing gasket 9 can also be provided between the inner walls of the inner cover plate 6 and 52.

[0037] A guide plate 7 is installed vertically and obliquely in the opposite direction of the rotating main shaft 22 on the water inlet side where the main pipe 51 connects to the tap water pipe.

[0038] When using this utility model:

[0039] By improving the existing tee pipe, production is facilitated. Furthermore, the installation and removal port 52 of the existing tee pipe can be opened through the outer cover plate 8 and the inner cover plate 6 during use, making it very convenient to remove the spherical turbine 21, which is beneficial for installation and maintenance.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made to the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
