Description

Technical Field

[0001] This invention relates to the field of water turbine technology, and in particular to a water turbine with an adjustable water inlet angle. Background Technology

[0002] An impulse turbine is a hydraulic prime mover that converts water energy into mechanical energy by using a special guide vane mechanism to draw a free jet of kinetic energy towards the runner's buckets. This jet causes the runner to rotate and perform work. Impulse turbines are suitable for high-head, low-flow power stations. Specifically, an impulse turbine is a high-head turbine (head exceeding 300-500m). Flow is introduced from the pressure pipe through nozzles, where the potential and kinetic energy of the high-pressure water flow is converted into a high-speed free jet of significant kinetic energy at the runner inlet. This jet acts on the buckets of the turbine runner, forcing the runner to rotate, which in turn drives the generator rotor to generate electricity. The kinetic energy of the water is converted into the mechanical energy of the runner, and the water flow rate is adjusted by nozzle needles installed within the nozzles. Traditional water turbines cannot adjust the angle of the water inlet, resulting in poor utilization of potential energy in relatively gentle water flows. In particular, the potential energy generated by the gentle water flow before entering the water turbine cannot adapt to various water flow conditions, thus limiting their widespread use. To maximize the efficiency of water resources and ensure more stable operation of the water turbine, it is essential to achieve maximum energy efficiency. Summary of the Invention

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0028] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0029] Example 1 Reference Figures 1-5 This embodiment provides a water turbine with an adjustable water inlet angle, including: a housing 100, a jet assembly 200 disposed above the housing 100, and a water inlet angle adjustment mechanism 300 disposed on the housing 100. The housing 100 includes a base 101, a water turbine chamber 102 connected to the base 101, and a water receiving cylinder 103 connected to the water turbine chamber 102. The water inlet angle adjustment mechanism 300 is disposed between the water receiving cylinder 103 and the water turbine chamber 102, and includes an adjustment chamber 301. A main shaft 302 is disposed within the adjustment chamber 301, and the main shaft 302 passes through... An adjusting plate 303 is connected to the adjusting chamber 301, and an adjusting column 304 is connected to the adjusting plate 303. The adjusting column 304 includes a first column body, on which a rotating wheel 304b is mounted. The rotating wheel 304b is connected to a connecting rod 304c. A braking block 304d is mounted inside the first column body, and a moving block 304e is mounted on the connecting rod 304c. The moving block 304e is positioned between the braking block 304d and the bottom of the first column body, and is bolted to the adjusting plate 303. By setting the water inlet angle adjusting mechanism 300, it can adapt to different directions and heights of jet flow. By rotating the rotating wheel 304b, the connecting rod mounted on the rotating wheel 304b moves upward (or downward), thereby driving the moving block 304e mounted on the connecting rod to move upward (or downward), thus adjusting the orientation of the water inlet of the water receiving cylinder 103, ensuring that the water inlet of the water receiving cylinder 103 is always aligned with the jet flow direction, maximizing the conversion of the kinetic energy of the water flow into mechanical energy.

[0030] Furthermore, the brake block 304d is fixed by bolts. By setting the brake block 304d to block the moving block 304, the moving block 304 is prevented from sliding out to the smooth part of the connecting rod 304c. The connecting rod 304c is provided with a smooth part and a threaded part, and the threaded part is used to fix the moving block 304.

[0031] Preferably, the jet assembly 200 includes a pressure water inlet chamber 201, which has an outlet 202 connected to a nozzle 203. A nozzle 204 is installed inside the nozzle 203. By using the nozzle 203 to draw water from the pressure water inlet chamber 201, and then using the nozzle 204 to convert the water flow into a high-speed jet that is directed towards the water turbine 102, the hydraulic loss is minimized.

[0032] Furthermore, a waterwheel 102a is installed inside the waterwheel chamber 102. The waterwheel 102a includes a waterwheel shaft 102a-1, which passes through the waterwheel chamber 102 and is connected to a drive wheel 102b. Several water receiving hoppers 102c are connected to the outer surface of the waterwheel shaft 102a-1. By installing the waterwheel 102a, the high-speed jet converted by the nozzle 204 impacts the water receiving hoppers 102c of the waterwheel 102a, generating an impact force that drives the waterwheel 102a to rotate, thereby driving the drive wheel 102b to rotate. The drive wheel 102b can be connected to a generator rotor to generate electricity.

[0033] Preferably, the water receiving hopper 102c includes a fixed base 102c-1, and a blade 102c-2 is connected to the fixed base 102c-1. The blade 102c-2 is semi-circular, and a notch is provided at the outer end of the blade 102c-2. By providing a notch at the outer end of the blade 102c-2, when the jet impacts the first water receiving hopper 102 and causes the first water receiving hopper 102 to rotate, the second water receiving hopper 102 will not block the jet directed at the first water receiving hopper 102 until the first water receiving hopper 102 has completely rotated past. This ensures that the jet is not interfered with by other water receiving hoppers 102, thus preventing resistance to the rotation of the water wheel 102a and causing a decrease in the rotational speed of the water wheel 102.

[0034] Implementation method: First, rotate the wheel 304b to adjust the orientation of the water inlet of the water receiving cylinder 103 so that the water inlet of the water receiving cylinder 103 is always consistent with the direction of the jet. Then, turn on the nozzle to convert the water flow into a high-speed jet that is directed toward the water wheel 102. The high-speed jet impacts the water receiving hopper 102c of the water wheel 102a, generating an impact force that drives the water wheel 102a to rotate, thereby driving the transmission wheel 102b to rotate. The transmission wheel 102b can be connected to the generator rotor to generate electricity.

[0035] Example 2 Reference Figures 1-8This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that: a rubber air cushion 103a is provided inside the water receiving cylinder 103, a spring 103a-1 is provided inside the rubber air cushion 103a, and the rubber air cushion 103a is connected to a control box 103b. By providing the rubber air cushion 103a inside the water receiving cylinder 103, when the jet is sprayed into the water receiving cylinder 103, it compresses the rubber air cushion 103a, forcing the gas inside the rubber air cushion 103a to the control box 103b, thereby controlling the control box 103b to activate the auxiliary rotation mechanism 400.

[0036] Furthermore, the control box 103b includes a straight tube 103b-1, one end of which is disposed within the inner cavity of the rubber air cushion 103a, and the other end is disposed within the control box 103b. A slide rail 103b-2 is disposed within the straight tube 103b-1, and a lifting block 103b-3 is disposed within the slide rail 103b-2. A conductor block 103b-4 is fixedly connected to the lifting block 103b-3, and a metal hook 103b-5 is disposed at the lower end of the conductor block 103b-4. When the gas in the rubber air cushion 103a is compressed against the straight tube 103b-1, the lifting block 103b-3 disposed on the straight tube 103b-1 is compressed downward by the gas and slides downward, causing the conductor block 103b-4 to move downward until it abuts against the metal hook 103b-5, thus triggering the circuit to connect.

[0037] Preferably, the metal hook 103b-5 is connected to a solenoid valve via a wire, and the solenoid valve is connected to an auxiliary rotating mechanism 400 via a wire. When the metal hook 103b-5 contacts the conductor block 103b-4, the solenoid valve is energized to switch the gas.

[0038] Furthermore, the auxiliary rotating mechanism 400 includes a second column 401, a reciprocating block 402 is provided inside the second column 401, a push-pull plate 403 is connected to the reciprocating block 402, a rotating rod 404 is connected to the push-pull plate 403, an auxiliary rotating wheel 405 is connected to the rotating rod 404, and the auxiliary rotating wheel 405 is connected to the water turbine shaft 102a-1. The auxiliary rotating mechanism 400 is connected via a solenoid valve. Compressed gas enters the bottom of the auxiliary rotating mechanism 400 through the solenoid valve, squeezing the reciprocating block 402 downward, which in turn moves the push-pull plate 403 downward, thereby causing the rotating rod 404 to rotate. Excess gas is discharged from the auxiliary rotating mechanism 400 and enters the solenoid valve. The solenoid valve core is then switched to reverse the airflow. Compressed gas enters the top of the auxiliary rotating mechanism 400 through the solenoid valve, squeezing the reciprocating block 402 upward, which in turn moves the push-pull plate 403 downward, thereby causing the rotating rod 404 to rotate. This reciprocating motion of the reciprocating block 402 up and down further drives the auxiliary rotor 405 to rotate, and the rotation of the auxiliary rotor 405 drives the water turbine shaft 102a-1 to rotate.

[0039] Preferably, a tailrace tank 102d is provided below the water turbine 102a, and a water outlet pipe is provided in the tailrace tank 102d. The water after being impacted by the jet is discharged from the water outlet pipe through the tailrace tank 102d.

[0040] Implementation: When the jet sprays into the water receiving cylinder 103, it compresses the rubber air cushion 103a, forcing the gas inside the air cushion 103a into the straight pipe 103b-1. The lifting block 103b-3, mounted on the straight pipe 103b-1, is compressed downwards by the gas, causing the conductor block 103b-4 to move downwards until it abuts against the metal hook 103b-5. This triggers the circuit, energizing the solenoid valve to switch the gas flow. The reciprocating block 402 in the auxiliary rotating mechanism 400 moves up and down through the gas switching, causing the auxiliary rotating wheel 405 to rotate, which in turn causes the water turbine shaft 102a-1 to rotate. When the jet spray impacts the water receiving hopper 102c of the water turbine 102a, it generates an impact force that further accelerates the rotation of the water turbine 102a, thereby driving the transmission wheel 102b to rotate and generate electricity.
