Description

Technical Field

[0001] This utility model relates to a marine turbine pump with a heat dissipation structure, and particularly to a marine turbine pump with a heat dissipation structure applied in the marine field. Background Technology

[0002] A turbine pump is a machine that uses the centrifugal force or thrust generated by the rotation of an impeller to transport fluids (such as liquids, gases, etc.). For some small and medium-sized ships, the turbine pump is usually installed in the engine room for centralized maintenance and management.

[0003] Chinese utility model patent CN201820457007.X discloses a high-efficiency and energy-saving marine pump, comprising a base, with a turbine housing 1 and a turbine housing 2 fixedly mounted on the base. End covers are respectively provided on both sides of the turbine housing 1 and turbine housing 2, with a through hole in the middle of each end cover. Impellers are respectively installed inside the turbine housing 1 and turbine housing 2, with a rotating shaft in the middle of each impeller. The rotating shafts of the impellers inside the turbine housing 1 and turbine housing 2 are connected by an electromagnetic clutch, and the rotating shaft of the impeller inside the turbine housing 2 is connected to the output shaft of a motor via a coupling. The motor is fixedly mounted to the base via a motor mounting bracket. This high-efficiency and energy-saving marine pump achieves adjustable pumping speed by adjusting the number of working impellers, increases outlet water pressure by adding an energy storage tank to meet long-distance spraying requirements, and achieves energy saving and high efficiency by adjusting the motor power.

[0004] Turbine pumps generate high temperatures during operation, but existing turbine pumps generally rely on heat exchange between themselves and the external gas for cooling, which is inefficient. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing turbine pumps generally rely on heat exchange between themselves and the external gas for cooling, which is inefficient.

[0006] To address the aforementioned problems, this utility model provides a marine turbine pump with a heat dissipation structure, including a turbine pump body, and further comprising:

[0007] The frame is a cube-shaped frame, and the turbine pump body is located inside the cube frame.

[0008] Multiple cavities are all located inside the lower edge of the frame;

[0009] Multiple motors are fixedly connected to the prism frame, and the output end of the motor passes through the prism frame and communicates with the cavity.

[0010] Multiple sets of rotating fan plates are equidistantly connected to the edges of the frame, with the two ends of each fan plate connected to the upper and lower edges respectively.

[0011] The transmission assembly is located inside the cavity and is used to transmit the rotational force from the motor output to the rotating fan plate.

[0012] The rotation of the motor causes the rotating fan plate to rotate through the transmission components, thereby generating an airflow from bottom to top to cool the turbine pump body.

[0013] The aforementioned marine turbine pump with a heat dissipation structure can cool the turbine pump and provide isolation and protection for it.

[0014] As a further improvement of this application, the transmission assembly includes a transmission shaft, a first bevel gear, and a second bevel gear. The transmission shaft is fixedly connected to the output end of the motor. Multiple sets of first bevel gears are fixedly connected to the transmission shaft at equal intervals. The second bevel gear is meshed with the first bevel gear and is fixedly connected to the rotating fan plate.

[0015] As a further improvement of this application, a rotating shaft is fixedly connected to the rotating fan plate. One end of the rotating shaft passes through the prism frame and is located in the cavity, and the through end is fixedly connected to the second bevel gear.

[0016] As a further improvement to this application, a mesh is installed on the side of the prism frame.

[0017] As a further improvement to this application, one of the partitions is rotatably connected to an inspection door.

[0018] As another improvement of this application, a mounting bracket is fixedly connected to the prism frame, and the mesh is installed on the mounting bracket.

[0019] In summary, by rotating the fan blades, an upward airflow can be generated, which allows the hot gas near the turbine pump body to flow rapidly, thereby dissipating heat from the turbine pump itself. At the same time, when not in use, it can act as a baffle to prevent other personnel from getting burned when the turbine pump is in use. Attached Figure Description

[0027] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figures 1-5 The diagram shows a marine turbine pump with a heat dissipation structure, including a turbine pump body 1, and further comprising: a prism frame 2, arranged in a cubic frame, with the turbine pump body 1 located within the cubic frame; multiple cavities, all disposed within the lower edges of the prism frame 2; multiple motors 401, fixedly connected to the prism frame 2, with the output ends of the motors 401 penetrating the prism frame 2 and communicating with the cavities; multiple rotating fan plates 3, rotatably connected at equal intervals within the edges of the prism frame 2, with both ends of the rotating fan plates 3 connected to the upper and lower edges respectively; and a transmission assembly disposed within the cavities, used to transmit the rotational force from the output ends of the motors 401 to the rotating fan plates 3; through the rotation of the motors 401, the rotating fan plates 3 are rotated via the transmission assembly, thereby generating an upward airflow that vents the turbine pump body 1. The fan plate 3 is designed for air cooling. When the fan plate 3 stops rotating, it acts as a baffle to prevent people from approaching. The transmission components include a drive shaft 402, a first bevel gear 403, and a second bevel gear 404. The drive shaft 402 is fixedly connected to the output end of the motor 401. Multiple sets of first bevel gears 403 are fixedly connected to the drive shaft 402 at equal intervals. The second bevel gear 404 meshes with the first bevel gear 403 and is fixedly connected to the fan plate 3. A rotating shaft 301 is fixedly connected to the fan plate 3. One end of the rotating shaft 301 passes through the prism frame 2 and is located in the cavity. The through end is fixedly connected to the second bevel gear 404. A mesh 6 is installed on the side of the prism frame 2. An inspection door 7 is rotatably connected to one set of mesh 6. A mounting bracket 5 is fixedly connected to the prism frame 2, and the mesh 6 is installed on the mounting bracket 5.

[0030] The turbine pump body 1 is fixed to a suitable position inside the cubic frame formed by the prism frame 2 by bolts and other connecting parts; the motor 401 is fixed to the prism frame 2 by bolts, and the output end extends into the cavity of the lower edge of the prism frame 2 and is fixedly connected to the drive shaft 402; the drive shaft 402 is installed in the cavity and is rotatably connected to the prism frame 2 by bearings and other components; the first bevel gear 403 is fixed to the drive shaft 402 by key connection and other means; the second bevel gear 404 is fixedly connected to the rotating shaft 301 on the rotating fan plate 3; the rotating shaft 301 passes through the prism frame 2 and is located in the cavity; the partition 6 is installed on the mounting bracket 5 by bolts and other means; the mounting bracket 5 is welded or bolted to the prism frame 2; the inspection door 7 is rotatably connected to the partition 6 by hinges and other means.

[0031] When the turbine pump body 1 generates heat during operation and needs to dissipate heat, the motor 401 is started. The output end of the motor 401 rotates, driving the transmission shaft 402 to rotate. The bevel gear 403 on the transmission shaft 402 rotates accordingly. Since the bevel gear 404 meshes with the bevel gear 403, the bevel gear 404 drives the rotating fan plate 3 to rotate around the rotating shaft 301. The angle of the rotating fan plate 3 is adjusted to generate an airflow from bottom to top. Outside air enters from below the frame 2 through the partition 6 and forms an upward airflow under the action of the rotating fan plate 3. The airflow passes around the turbine pump body 1 and carries away the heat, achieving air cooling.

[0032] When the turbine pump body 1 is not working or does not require a large amount of heat dissipation, the rotating fan plate 3 can be positioned at a suitable angle, such as... Figure 2 As shown, the turbine pump body 1 is set up in parallel, which can play a certain role in shielding and preventing personnel from directly contacting the turbine pump body 1, thus reducing the risk of burns. If the turbine pump body 1 needs to be inspected, the inspection door 7 can be opened and the staff can enter the interior to operate.

[0033] The rotating fan plate 3 has a certain fan-shaped structure. One end of it is fixedly connected to the rotating shaft 301. Both ends of the rotating shaft 301 are rotatably connected to the frame 2 through bearings, etc., to ensure that the rotating fan plate 3 rotates smoothly, changes the angle stably during rotation, and effectively guides the airflow direction.

[0034] The bevel gear 403 and bevel gear 404 ensure the stability and efficiency of the transmission, and ensure reliable power transmission during long-term use, so that the rotating fan plate 3 can rotate stably.

[0035] The mesh 6 can effectively block debris in the ship's environment, such as rope fragments and small floating objects, from entering the prism frame 2 and affecting the operation of the turbine pump body 1 and the heat dissipation structure. At the same time, it can ensure sufficient ventilation so that the airflow can pass through smoothly without affecting the heat dissipation effect. Meanwhile, the mesh 6 can be omitted and the inspection door 7 can be directly installed on the prism frame 2.

[0036] The transmission component driven by motor 401 rotates the rotating fan plate 3 to generate an upward airflow, which can quickly dissipate heat near the turbine pump body 1. Compared with the traditional single heat dissipation method, the heat dissipation is more proactive and efficient, effectively reducing the working temperature of the turbine pump body 1 and improving its working stability and service life.

[0037] The prism frame 2, the partition net 6, and the rotating fan plate 3 when not in operation together constitute a protective structure that can block debris from entering, prevent personnel from directly contacting the turbine pump body 1, reduce safety hazards such as burns, and meet the equipment protection requirements of the complex working environment of ships.

[0038] The installation of the inspection door 7 facilitates regular inspection and maintenance of the turbine pump body 1 by staff. The design of components such as the mounting bracket 5 ensures the stability of the installation of each structure. The overall structure is simple and reasonable, easy to operate and maintain, and has good practicality and applicability.

[0039] like Figure 3 As shown, the area with the inspection door 7 does not have a rotating fan plate 3, which facilitates the entry of personnel. At the same time, when the rotating fan plate rotates, it will not come into contact with the partition 6 and the turbine pump body 1.

[0040] 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.
