Description

Technical Field

[0001] This utility model belongs to the field of turbine pump technology, specifically, it relates to a marine turbine pump with a noise reduction structure. Background Technology

[0002] Marine turbine pumps are a new type of energy recovery device. They have the advantages of fewer rotating parts, no need for dynamic seals, and reliable operation. Therefore, they are widely used in the field of liquid residual pressure energy recovery and utilization, and are core equipment in marine power systems, cooling systems, ballast systems, etc.

[0003] Turbine pumps consist of a turbine side and a pump side. The turbine side is equipped with a turbine impeller, while the pump side is equipped with a pump impeller that is fixed to the turbine impeller via a central shaft. During operation, the high-pressure liquid on the turbine side impacts the turbine impeller to rotate, thereby driving the pump impeller to rotate and pressurizing the low-pressure liquid on the pump side. However, when water flows into the turbine pump for impact and repressurization, it generates significant noise. Furthermore, due to the enclosed space and dense equipment on ships, the noise from turbine pumps not only affects the working environment of the crew but may also be transmitted through the ship's structure, causing resonance and accelerating equipment aging. Utility Model Content

[0004] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing marine turbine pumps are noisy, which can easily affect the working environment of crew members and the use of electrical equipment.

[0005] To address the aforementioned problems, this utility model provides a marine turbine pump with a noise reduction structure, comprising a housing, a turbine pump body, and a drive motor. Both the turbine pump body and the drive motor are fixedly installed within the housing. The input end of the turbine pump body is fixedly connected to the drive end of the drive motor. A first noise reduction cylinder is fixedly installed and flows through the input end of the turbine pump body, and a second noise reduction cylinder is fixedly installed and flows through the output end of the turbine pump body. Sliding collars are slidably installed within both the first and second noise reduction cylinders. A rotating blade ring is rotatably installed within the sliding collar, and multiple drive blades are evenly installed within the rotating blade ring. A tension buffer spring and a compression buffer spring are fixedly installed on the sliding collar, and the other ends of both the tension and compression buffer springs are fixedly connected to the first and second noise reduction cylinders.

[0006] As a further improvement of this application, the length of the compression buffer spring is greater than the length of the tension buffer spring, which facilitates both tensioning and compression.

[0007] As a further improvement of this application, the tension buffer springs in the first noise reduction cylinder and the second noise reduction cylinder are both close to the input ports of the first noise reduction cylinder and the second noise reduction cylinder, and the compression buffer springs in the first noise reduction cylinder and the second noise reduction cylinder are both close to the output ports of the first noise reduction cylinder and the second noise reduction cylinder, thereby improving the tension and compression effect.

[0008] As a further improvement of this application, a first limiting slider is fixedly installed on the outer wall surface of the sliding collar, and a limiting groove matching the first limiting slider is provided in the first noise reduction cylinder and the second noise reduction cylinder, so as to facilitate the control of the sliding collar.

[0009] As a further improvement of this application, a second row of sliders is fixedly installed on the outer wall of the rotating propeller ring, and a limiting groove matching the second row of sliders is provided in the sliding collar to facilitate the control of the rotation of the rotating propeller ring.

[0010] In summary, this application reduces the impact force of the water flow by converting the kinetic energy of the water flow impact into the elastic potential energy of the tension and compression buffer springs, the kinetic energy of the sliding collar movement, and the kinetic energy of the rotating paddle ring. This prevents the water flow impact force from colliding with the equipment, thus reducing the noise generated by the water flow impact on the internal drive parts of the equipment. This achieves a noise reduction effect, protects the working environment of the crew, and extends the service life of the equipment. Attached Figure Description

[0017] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0018] Please refer to Figure 1-4As shown, a marine turbine pump with a noise reduction structure includes a housing 1, a turbine pump body 2, and a drive motor 3. The turbine pump body 2 and the drive motor 3 are both fixedly installed in the housing 1. The input end of the turbine pump body 2 is fixedly connected to the drive end of the drive motor 3. A first noise reduction cylinder 4 is fixedly installed and flows through the input end of the turbine pump body 2. A second noise reduction cylinder 5 is fixedly installed and flows through the output end of the turbine pump body 2. A sliding collar 6 is slidably installed in both the first noise reduction cylinder 4 and the second noise reduction cylinder 5. A rotating blade ring 9 is rotatably installed in the sliding collar 6. Multiple drive blades 10 are evenly installed in the rotating blade ring 9. A tension buffer spring 7 and a compression buffer spring 8 are fixedly installed on the sliding collar 6. The other ends of the tension buffer spring 7 and the compression buffer spring 8 are fixedly connected to the first noise reduction cylinder 4 and the second noise reduction cylinder 5.

[0019] The length of the compression buffer spring 8 is greater than the length of the tension buffer spring 7. The tension buffer springs 7 in the first noise reduction cylinder 4 and the second noise reduction cylinder 5 are both close to the input ports of the first noise reduction cylinder 4 and the second noise reduction cylinder 5. The compression buffer springs 8 in the first noise reduction cylinder 4 and the second noise reduction cylinder 5 are both close to the output ports of the first noise reduction cylinder 4 and the second noise reduction cylinder 5. When water enters the input end of the turbine pump body 2, the water enters from the input end of the first noise reduction cylinder 4, thereby driving the sliding collar 6 to slide inside the first noise reduction cylinder 4. The sliding collar 6 pulls the tension buffer spring 7 and compresses the compression buffer spring 8. When the water pressure decreases, the tension buffer spring 7 and the compression buffer spring 8 return to their original state, pulling the sliding collar 6 to slide in the opposite direction. When water enters the output end of the turbine pump body 2, the water enters from the input end of the second noise reduction cylinder 5, thereby driving the sliding collar 6 to slide inside the first noise reduction cylinder 4. The sliding collar 6 pulls the tension buffer spring 7 and compresses the compression buffer spring 8. When the water pressure decreases, the tension buffer spring 7 and the compression buffer spring 8 return to their original state, pulling the sliding collar 6 to slide in the opposite direction.

[0020] A first limiting slider 601 is fixedly installed on the outer wall of the sliding collar 6. The first noise reduction cylinder 4 and the second noise reduction cylinder 5 are provided with limiting grooves that match the first limiting slider 601. The sliding of the sliding collar 6 is restricted by the first limiting slider 601 and the limiting grooves, so as to prevent the sliding collar 6 from rotating or sliding off within the first noise reduction cylinder 4 or the second noise reduction cylinder 5.

[0021] A second row of sliders 901 is fixedly installed on the outer wall of the rotating propeller ring 9. A limiting groove 602 matching the second row of sliders 901 is provided in the sliding collar 6. The rotation of the rotating propeller ring 9 is restricted by the second row of sliders 901 and the limiting groove 602, so as to prevent the rotating propeller ring 9 from sliding or rotating and deviating in the sliding collar 6.

[0022] When a strong current of water enters the turbine pump body 2 from the input end of the first noise reduction cylinder 4, the water will impact the drive blades 10 on the rotating impeller ring 9. The impact force of the water will cause the rotating impeller ring 9 to rotate and the sliding collar 6 to slide. The tension buffer spring 7 is stretched and the compression buffer spring 8 is compressed. During the intervals between the water flows, the sliding collar 6 will slide back to its original position under the elastic force of the tension buffer spring 7 and the compression buffer spring 8, and continue to slide after the next wave of water arrives.

[0023] After the water flow is compressed inside the turbine pump body 2, it enters the second noise reduction cylinder 5 from the output end of the turbine pump body 2. This also causes the sliding collar 6 inside the second noise reduction cylinder 5 to slide and the rotating blade ring 9 to rotate, converting the impact force of the water flow into elastic force and the force of the rotating blade ring 9.

[0024] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
