Description

Technical Field

[0001] The utility model relates to a transmission mechanism, in particular to an inclined turbine transmission mechanism for a floating pump. Background Art

[0002] Currently, horizontal gasoline engines are commonly used in lawn mowers, small generators, gardening tools, etc. Because they have a low center of gravity when lying down, they are also very suitable for equipment that requires a low center of gravity, such as boat-shaped floating pumps.

[0003] However, the oil reservoir design of a horizontal gasoline engine is stable, allowing for a relatively even accumulation of oil. This requires slightly tilting or moving the engine to completely drain the oil during oil changes, making subsequent maintenance more inconvenient when used with a boat-shaped floating pump. Furthermore, if a horizontal gasoline engine is overfilled with oil during operation or storage, or if an unsuitable oil (such as one with too low a viscosity) is used, the oil will more easily flow into the combustion chamber when the engine is horizontal, causing oil burning. Summary of the Invention

[0004] In view of this, the present invention is to solve the problem of oil burning in existing horizontal gasoline engines during use, and provides a tilted turbine transmission mechanism for a floating pump that does not require changing the structure of the gasoline engine, ensures its center of gravity is stable, and prevents oil from entering the combustion chamber and causing oil burning.

[0005] The technical solutions to be solved by the present invention are as follows:

[0006] The inclined turbine transmission mechanism for a floating pump includes a turbine connected to the power output end of a gasoline engine, and is characterized in that: the turbine is placed in a turbine chamber on the inner side of a matching volute, and the turbine chamber is arranged at an angle of 45 degrees ± 15 degrees to the horizontal plane in accordance with the direction of the turbine axle; a water inlet is provided at the bottom of the turbine chamber, and the outside of the water inlet is a water inlet pipe integrated with the turbine chamber. The internal pipe direction of the water inlet pipe is coaxial with the turbine axle in the turbine chamber, and the pipe body of the water inlet pipe also has a mounting surface that tends to be bevel the outer side wall of the turbine chamber.

[0007] Preferably, the turbine also has a water outlet, which is arranged on one side of the water inlet and located at the bottom of the turbine chamber, and part of the internal space is expanded outward from the side wall of the turbine chamber close to the water outlet, thereby forming a water outlet area that is integrated with and communicated with the turbine chamber.

[0008] Preferably, the turbine further comprises a water outlet pipe extending from a water outlet at the bottom of the turbine chamber, and an exhaust valve is mounted on the water outlet pipe.

[0009] Preferably, the side wall of the turbine chamber on the same side as the installation surface of the water inlet pipe body is an inclined side wall that is continuous with or parallel to the installation surface of the water inlet pipe body.

[0010] The beneficial effects of the utility model are as follows:

[0011] Compared to existing technologies, the present invention tilts the turbine drive mechanism, indirectly achieving an inclined placement of the horizontal gasoline engine oil sump, preventing oil from entering the combustion chamber and causing oil burning. The water inlet pipe also features a mounting surface that bevels the turbine chamber's outer wall, ensuring the horizontal gasoline engine's operating center of gravity remains stable, ensuring operational stability.

[0017] The following detailed description of embodiments of the present invention's technical solutions is provided in conjunction with the accompanying drawings. The following embodiments are intended solely to more clearly illustrate the present invention's technical solutions, providing numerous specific details to provide a more thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention can be implemented without one or more of these details. In these examples, some technical features known in the art are not described to avoid confusion with the present invention.

[0018] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. These embodiments are therefore intended only as examples and should not be used to limit the scope of protection of the present invention.

[0019] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0020] A tilted turbine transmission mechanism for a floating pump includes a turbine 1 connected to the output of a gasoline engine A, located within a turbine chamber 2 within a volute. The turbine chamber 2 is arranged at an angle of 45 degrees ± 15 degrees to the horizontal, aligned with the axis of the turbine 1. This ensures that the rotational direction of the turbine 1 aligns with the tilt of the turbine chamber 2. A water inlet 3 is provided at the bottom of the turbine chamber 2. An inlet pipe 4, integrally designed with the turbine chamber 2, extends from the outside of the inlet 3. The internal direction of the inlet pipe 4 is coaxial with the axis of the turbine 1 within the turbine chamber 2, ensuring smooth water flow into the turbine 1 area. Compared to vertical or horizontal inlet pipe configurations, this eliminates significant pressure loss when water enters the pump body, improving the overall pumping performance to a certain extent. The inlet pipe 4 also features a mounting surface 5 that tends to be chamfer the outer sidewall of the turbine chamber.

[0021] During implementation, the installation surface 5 of the water inlet pipe 4 allows the turbine transmission mechanism to be installed at the bottom of the hull B of the boat-shaped floating pump. The turbine chamber 2 with an integrated design of the water inlet pipe 4 can form an angle α of 45 degrees ± 15 degrees with the horizontal plane, which will lower the height of the water inlet pipe 5 to reduce the corresponding center of gravity height raised after the gasoline engine is installed at an angle, ensuring that the center of gravity of the gasoline engine does not change significantly, thereby affecting the overall center of gravity change of the boat-shaped floating pump floating on the water surface, and ensuring that the pump still has the stability brought by the lower center of gravity when in use, so that the floating hull will not be offset, spin on the water surface, or capsize during operation.

[0022] During implementation, the turbine chamber 2 is optimally angled at 45 degrees to the horizontal plane, in line with the axis of the turbine 1. This maintains the center of gravity at this point. At 30 degrees, the height of the turbine chamber 2 decreases if the space inside is not considered. However, given the required working space for the turbine within the chamber, the overall center of gravity shifts rearward while remaining unchanged. This change does not significantly impact the pump's stability. At 60 degrees, the center of gravity increases, shifting rearward, but remains within the stable range.

[0023] When the temperature is lower than 30 degrees, there is a certain probability that the oil pool will enter the fuel chamber. When the temperature is higher than 60 degrees, the center of gravity will have a greater probability of affecting the stability of the boat-shaped floating pump during operation.

[0024] Furthermore, as an improvement to the present invention, the turbine 1 further comprises a water outlet 6, which is located at the bottom 21 of the turbine chamber 2 and is arranged on one side of the water inlet 3. A portion of the internal space is expanded outward from the sidewall of the turbine chamber 2 near the water outlet 6, thereby forming a water outlet area 7 that is integral with and communicates with the turbine chamber. This water outlet area 7 ensures that the direction of the water flow generated by the turbine 1 during rotation does not produce uneven flow due to sudden changes, thereby preventing the turbine 1 from experiencing a decrease in efficiency during operation. It also reduces pressure loss caused by water flow obstruction inside the turbine, improves the fluidity of the water flow, and helps maintain stable pumping efficiency.

[0025] During implementation, the water outlet 6 corresponding to the water outlet area 7 is located near the bottom area of ​​the turbine chamber projected from the periphery of the turbine, and the peripheral side walls of the water outlet area 7 extend smoothly to the inner side of the water outlet 6. When the turbine 1 rotates, it drives the water flow from the water inlet into the water outlet and flows smoothly along the trend water flow curve formed around the water outlet area into the water outlet for discharge, thereby optimizing the pumping effect.

[0026] In addition, the water outlet area 7 is actually part of the turbine chamber, and the two are completely connected. When the pump is operating, the water flow channel is optimized, the turbulent effect of the fluid is reduced, and the interaction between the turbine 1 blades and the water flow is ensured to be smoother and more efficient.

[0027] Furthermore, as an improvement to the present invention, the turbine further comprises a water outlet pipe 8 , which extends from a water outlet 6 at the bottom of the turbine chamber 2 , and an exhaust valve 9 is mounted on the water outlet pipe 8 .

[0028] During implementation, the angle β between the extension direction of the outlet pipe and the direction of the water inlet pipe body is within 30 degrees, ensuring that the outlet pipe is still the normal water outlet position on the boat-shaped floating pump.

[0029] Furthermore, as an improvement to the present invention, the side wall of the turbine chamber 2 on the same side as the water inlet pipe 4 body mounting surface 5 is an inclined side wall 22 that is continuous with or parallel to the water inlet pipe 4 body mounting surface.

[0030] During implementation, the inclined side wall of the turbine chamber 1 and the water inlet pipe 4 body installation surface trend continues or is parallel to each other, and it is necessary to ensure that the turbine 1 blades inside it cannot touch the inner surface of the inclined side wall 22, and the distance from the turbine 1 to the inner surface is at least greater than 2 mm.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
