Description

Technical Field

[0001] This utility model relates to the field of water turbine technology, and in particular to a spiral water turbine with a flow guiding component. Background Technology

[0002] A propeller turbine is a hydroelectric power generation device suitable for low-head, high-flow conditions. Its structure resembles a propeller or Archimedean spiral, with blades in a continuous helical shape. Water flow propels the blades to rotate axially or obliquely, converting the kinetic energy of the water into mechanical energy. Compared to traditional reaction or impulse turbines, it has a simpler structure, no complex water guide system, and lower water quality requirements. It is suitable for low-head (typically <5 meters) scenarios such as irrigation canals, rivers, and drainage ditches, and is often used in micro-hydropower stations or energy-saving water lifting. It features stable operation, convenient maintenance, and strong adaptability.

[0003] Existing spiral turbines have a single water output method and lack flexible diversion function, making it difficult to adapt to multi-purpose and multi-outlet requirements. The water output path is fixed and cannot distribute water flow as needed, which limits their flexible application and functional expansion in scenarios such as multi-channel water supply.

The connecting block has an inlet channel, and the outlet of the spiral turbine body is fixedly connected to the inlet channel. The inner wall of the inlet channel, on the side away from the spiral turbine body, has multiple longitudinally distributed flow guiding channels, which are arranged laterally. An outlet pipe communicating with the flow guiding channels is fixedly connected to the side of the connecting block away from the spiral turbine body. A shut-off valve is installed on the outlet pipe. The upper end of the connecting block has an opening communicating with the inlet channel and the flow guiding channels. A cover plate corresponding to the opening is rotatably connected to the upper end of the connecting block. A rubber gasket is fixedly connected to the lower end of the cover plate. Multiple locking screws are provided on the upper end of the cover plate, and the cover plate is fixed to the connecting block by the locking screws.

[0007] Preferably, the upper end of the cover plate is provided with an observation port, and a transparent plate is fixedly embedded in the observation port.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A spiral turbine with a flow guiding component includes a spiral turbine body 1 and a connecting block 2. The connecting block 2 is used to guide water in conjunction with an inlet trough 11 and a flow guiding trough 12. The connecting block 2 is provided with an inlet trough 11 for water flow. The outlet of the spiral turbine body 1 is fixedly connected to the inlet trough 11 in the connecting block 2. The inner walls of the inlet trough 11, the flow guiding trough 12 and the outlet pipe 3 are all fixed with an epoxy coating for rust prevention. The inner wall of the inlet trough 11 and the side away from the spiral turbine body 1 are provided with multiple longitudinally distributed flow guiding troughs 12 for water flow. The flow guiding troughs 12 are arranged horizontally.

[0022] In this embodiment, a water outlet pipe 3 communicating with the guide channel 12 is fixedly connected to the side of the connecting block 2 away from the spiral turbine body 1 for water discharge. A shut-off valve 6 is installed on the water outlet pipe 3. A support ring 4 is fixedly sleeved on the outer wall of the water outlet pipe 3 for supporting the water outlet pipe 3. One side of the support ring 4 is fixedly connected to the outer wall of the connecting block 2. A flange 5 is fixedly connected to the end of the water outlet pipe 3 away from the connecting block 2 for facilitating the connection of the water outlet pipe 3 with other pipelines.

[0023] In this embodiment, the upper end of the connecting block 2 is provided with an opening communicating with the water inlet trough 11 and the guide trough 12. The upper end of the connecting block 2 is rotatably connected with a cover plate 7 corresponding to the opening for closing the opening. The lower end of the cover plate 7 is fixedly connected with a rubber gasket 8 for improving the sealing performance. The upper end of the cover plate 7 is provided with multiple locking screws 9 for fixing the cover plate 7. The cover plate 7 is fixed to the connecting block 2 by the locking screws 9. The upper end of the cover plate 7 is provided with an observation port. A transparent plate 13 is fixedly embedded in the observation port for the user to observe the internal situation. The transparent plate 13 is made of transparent tempered glass. The upper end of the cover plate 7 is fixedly connected with a semi-circular handle 10 for the user to easily lift the cover plate 7.

[0024] In this embodiment, water first flows out of the spiral turbine body 1 and enters the inlet tank 11. The water in the inlet tank 11 is guided to the corresponding outlet pipes 3 through multiple guide channels. Then, the water is guided to different water usage points through the outlet pipes 3, thereby achieving effective water diversion from the spiral turbine body 1 and meeting the needs of multi-channel water supply and flexible diversion. By operating the opening and closing of each shut-off valve 6, independent opening and closing control of each single water path can be achieved. In addition, when maintenance and cleaning are required, simply unscrew the locking screws 9 of the fixed cover plate 7 and then unscrew the cover plate 7 to perform maintenance and cleaning work on the inside of the inlet tank 11 and guide channels 12 through the opening. After maintenance and cleaning are completed, the cover plate 7 is closed and the locking screws 9 are tightened again. With the help of the rubber gasket 8, the opening can be reliably closed and sealed to ensure normal operation of the equipment.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
