Description

Technical Field

[0001] This utility model relates to a power generation transmission mechanism, and in particular to a modular shaft belt power generation transmission mechanism applied in the field of shaft belt power generation. Background Technology

[0002] A shaft-driven generator transmission mechanism is a device that uses the main shaft power of ships, large machinery and other equipment to drive a generator to generate electricity. It is commonly used in ocean-going vessels, oil tankers, large industrial equipment and other occasions where efficient power generation is required and space is limited, in order to improve energy utilization efficiency.

[0003] When the shaft-driven generator transmission mechanism is in use, the main shaft is driven to rotate by the host machine. Part of the power is diverted to the generator through the gearbox or clutch to improve the resource utilization rate. However, when the gearbox changes speed, the multiple gears inside mesh with each other, which generates a lot of heat. Since the expansion coefficients of the gears and the housing are different, it may cause backlash jamming or cause impact vibration.

[0004] To address the issue of high temperatures caused by the rotation of multiple gears inside a gearbox, lubricating oil is currently the primary heat transfer medium. The frictional heat is conducted to the gearbox wall through the flow of the oil, and then dissipated through heat exchange (convection, radiation, etc.) between the gearbox and the external environment. However, relying solely on the contact between the lubricating oil and the gearbox wall to dissipate heat from the inside of the gearbox is ineffective and may affect transmission efficiency. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when power is split through the gearbox, the gearbox will generate a lot of heat due to the friction of multiple gears. Currently, the frictional heat is mainly conducted to the gearbox wall by lubricating oil for heat dissipation. However, the heat dissipation effect of simply relying on the contact between lubricating oil and the gearbox wall to dissipate heat inside the gearbox is poor and may affect the transmission efficiency.

[0006] To address the aforementioned problems, this utility model provides a modular shaft-driven power transmission mechanism, comprising a gearbox, with positioning plates fixedly connected to both ends of the gearbox. The input and output shafts of the gearbox movably pass through the two positioning plates, respectively. A gear chain assembly is fitted onto the outer surface of the input shaft on the left side of the gearbox, and a generator is fixedly connected to the output shaft on the right side of the gearbox. A heat dissipation assembly is movably fitted onto the outer surface of the gearbox, comprising two mounting shells movably fitted onto the outer surface of the gearbox. Multiple baffles are fixedly connected inside the mounting shells, and a pressing strip is fixedly connected to one end of each of the two mounting shells. Multiple mounting rods are provided below the gearbox, with adjusting sleeves rotatably fitted onto the outer surfaces of the mounting rods. An L-shaped rod is fixedly connected to the outer surface of the adjusting sleeve, with the end of the L-shaped rod away from the adjusting sleeve fixedly connected to an adjacent mounting shell. Two infusion tubes are provided below the two mounting shells, and two positioning strips are provided above the gearbox. The lower ends of the positioning strips are fixedly connected to adjacent mounting shells, and limit grooves are chiseled into one end of each of the two positioning strips. Limiting strips are inserted into both limit grooves, and a pull plate is fixedly connected to the right end of each limiting strip.

[0007] In the aforementioned modular shaft-driven power transmission mechanism, in addition to the traditional method of cooling through lubricating oil, a detachable heat dissipation component is installed on the outer surface of the gearbox. When the traditional heat dissipation effect is poor, the heat dissipation component can be installed on the outer surface of the gearbox. By supplying coolant to the inside of the mounting housing, heat exchange occurs on the gearbox wall, indirectly dissipating heat from multiple gears inside the gearbox. This effectively prevents multiple gears from getting stuck in the backlash or causing impact vibration due to high temperature, thus effectively improving the transmission effect.

[0008] As a further improvement of this application, the extrusion strips are elastic, and the two extrusion strips fit together.

[0009] As a further improvement of this application, the longitudinal section of the limiting groove is L-shaped, the longitudinal section of the limiting strip is U-shaped, and the limiting strip and the pull plate are located above the positioning plate.

[0010] As a further improvement of this application, both the mounting shell and the baffle are arc-shaped, one end of the baffle does not contact the inner wall of the mounting shell, and multiple baffles are distributed in an alternating manner.

[0011] As another improvement of this application, the infusion tubing includes two telescopic hoses that are respectively fixedly connected to the bottom of two mounting shells. The ends of the two telescopic hoses away from the mounting shells are jointly fixedly connected to a T-shaped transfer tube. The lower end of the transfer tube is fixedly connected to an L-shaped inlet tube. The telescopic hoses are located between the outermost baffle and the longitudinal inner wall of the mounting shell.

[0012] As another improvement of this application, the infusion tube is replaced with two L-shaped delivery tubes. The upper end of the delivery tubes is fixedly connected to the adjacent mounting shell. The two transversely opposite delivery tubes are distributed in a mirror image. The delivery tubes are located between the outermost baffle and the longitudinal inner wall of the mounting shell.

[0013] In summary, in practical applications, an external thermometer can be used to detect the temperature of the gearbox's outer wall. If the gearbox's outer wall temperature is too high, the two mounting shells can be opened and fitted onto the gearbox's outer surface. Then, limit strips are inserted into the two positioning strips to limit and fix the two mounting shells. Coolant is then delivered to the inside of the mounting shells through a liquid inlet pipe. The coolant flows along the arrangement of multiple baffles, ensuring full contact between the coolant and the gearbox's outer wall, thereby effectively improving heat exchange and indirectly dissipating heat from the multiple gears inside the gearbox. This effectively prevents high temperatures from causing backlash jamming or impact vibrations in the gears, thus effectively improving the transmission efficiency. Attached Figure Description

Detailed Implementation

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1 and Figure 2 The diagram illustrates a modular shaft-driven power generation transmission mechanism, including a gearbox 1. Those skilled in the art can select a suitable model of gearbox 1 according to actual needs, such as BXS60-800. A temperature sensor is installed inside the gearbox 1 to monitor its temperature. When the temperature is too high, a heat dissipation assembly cools it down. Those skilled in the art can select a suitable model of temperature sensor according to actual needs, such as WZP-231. Positioning plates 2 are fixedly connected to both ends of the gearbox 1. The input shaft and output shaft of the gearbox 1 respectively movably pass through the two positioning plates 2. The input shaft on the left side of the gearbox 1... The outer surface of the gearbox 1 is fitted with a gear chain assembly 3, and the output shaft on the right side of the gearbox 1 is fixedly connected to a generator 4. Those skilled in the art can select a suitable model of generator 4 according to actual needs, such as EYC11000XE. The outer surface of the gearbox 1 is movably fitted with a heat dissipation assembly. The other end of the gear chain assembly 3 is mounted on the main shaft of the unit. The rotation of the main shaft causes the gear chain assembly 3 to rotate, thereby causing the input shaft of the gearbox 1 to rotate, driving multiple gears inside the gearbox 1 to rotate. The speed is changed through the multiple gear transmissions inside the gearbox 1, and then connected to the generator 4 through the output shaft of the gearbox 1 to generate electricity.

[0027] Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The heat dissipation assembly includes two mounting shells 5 movably fitted onto the outer surface of the gearbox 1. Multiple baffles 6 are fixedly connected inside the mounting shells 5. Both the mounting shells 5 and the baffles 6 are arc-shaped. One end of each baffle 6 does not contact the inner wall of the mounting shell 5. The multiple baffles 6 are staggered, and the coolant flows along the arrangement of the baffles 6, effectively extending the flow distance of the coolant and ensuring full contact between the coolant and the outer wall of the gearbox 1. An extrusion strip 7 is fixedly connected to one end of each mounting shell 5. The extrusion strip 7 is elastic, and the two extrusion strips 7 fit together. When the two mounting shells 5 are opened and closed, the extrusion strips 7 compress against each other. For ease of operation, multiple mounting rods 8 are provided below the gearbox 1. Adjusting sleeves 9 are rotatably fitted onto the outer surface of each mounting rod 8. An L-shaped rod 10 is fixedly connected to the outer surface of the adjusting sleeve 9. The end of the L-shaped rod 10 away from the adjusting sleeve 9 is fixedly connected to an adjacent mounting shell 5. When the mounting shell 5 rotates, the adjusting sleeve 9 rotates on the surface of the mounting rods 8, thus facilitating the opening and closing of the two mounting shells 5. Two infusion pipes 11 are provided below the two mounting shells 5. The infusion pipes 11 deliver coolant into the interior of the mounting shell 5. The coolant flows along the arrangement of multiple baffles 6 and then exits from another infusion pipe 11, achieving circulation and thus improving the coolant supply. The tube 11 includes two telescopic hoses 111, which are respectively fixedly connected to the bottom of the two mounting shells 5. The telescopic hoses 111 effectively prevent the mounting shells 5 from colliding and obstructing each other when they are opened and closed. The ends of the two telescopic hoses 111 away from the mounting shells 5 are fixedly connected to a T-shaped transfer tube 112. The lower end of the transfer tube 112 is fixedly connected to an L-shaped inlet tube 113. The telescopic hoses 111 are located between the outermost baffle 6 and the longitudinal inner wall of the mounting shell 5. Two positioning strips 12 are provided above the gearbox 1. The lower end of the positioning strips 12 is fixedly connected to the adjacent mounting shell 5. The corresponding ends of the two positioning strips 12 are each chiseled with a limit groove 13. A limiting strip 14 is inserted into the slot 13. A pull plate 15 is fixedly connected to the right end of the limiting strip 14. The longitudinal section of the limiting slot 13 is L-shaped, and the longitudinal section of the limiting strip 14 is U-shaped. The limiting strip 14 and the pull plate 15 are located above the positioning plate 2. The limiting strip 14 can be inserted into the two limiting slots 13 to limit and fix the two positioning strips 12, thereby installing and fixing the two mounting shells 5 without the need for bolts or other fixing methods. If it is necessary to maintain the internal parts of the gearbox 1 in the future, the limiting strip 14 can be directly removed, and the heat dissipation component can be removed by opening the mounting shell 5, which facilitates the maintenance of the gearbox 1 in the future.

[0028] In operation, the other end of the gear chain assembly 3 is mounted on the main shaft of the unit. The rotation of the main shaft causes the gear chain assembly 3 to rotate, which in turn causes the input shaft of the gearbox 1 to rotate, driving multiple gears inside the gearbox 1 to rotate, thus changing the speed. The output shaft of the gearbox 1 is then connected to the generator 4 to generate electricity. When the multiple gears inside the gearbox 1 rotate, they generate frictional heat, causing the overall temperature of the gearbox 1 to rise. Coolant is then delivered to the mounting housing 5 through the liquid delivery pipe 11. The coolant flows along the arrangement of multiple baffles 6 and is then discharged from another liquid delivery pipe 11, achieving circulation. This ensures that the coolant is in full contact with the outer wall of the gearbox 1, thereby effectively improving the heat exchange effect and indirectly dissipating heat from the multiple gears inside the gearbox 1. This effectively prevents the multiple gears from getting stuck due to high temperature or causing impact vibration, thus effectively improving the transmission effect.

[0029] Second implementation method:

[0030] This embodiment is based on the first embodiment, but replaces the infusion tube 11 with two L-shaped delivery tubes 16, while the rest remains the same as the first embodiment.

[0031] Figure 8 The diagram shows that the infusion tube 11 is replaced with two L-shaped delivery tubes 16. The delivery tubes 16 can be flexible pipes to effectively prevent collisions between the mounting shell 5 when it is opened and closed. The upper end of the delivery tube 16 is fixedly connected to the adjacent mounting shell 5. The two transversely opposite delivery tubes 16 are distributed in a mirror image. The delivery tubes 16 are located between the outermost baffle 6 and the longitudinal inner wall of the mounting shell 5.

[0032] Coolant is delivered to the mounting housing 5 through two delivery pipes 16 on the mounting housing 5. The coolant in one mounting housing 5 flows from left to right, and the delivery fluid in the other mounting housing 5 flows from right to left, so that both ends of the gearbox 1 exchange heat with the coolant at a lower temperature, thereby effectively preventing the temperature on one side of the gearbox 1 from being higher than the temperature on the other side and effectively improving the heat dissipation effect.

[0033] 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.
