Description

Technical Field

[0001] This invention relates to the field of gearbox technology, specifically to a gearbox structure with high-efficiency heat exchange. Background Technology

[0002] Gearboxes generate a lot of heat during operation, requiring heat exchange to ensure normal operation. Air cooling is the most common and efficient way to dissipate heat in gearboxes. By using a fan to drive airflow over the surface of the heat sink, heat is carried away, greatly improving the heat dissipation efficiency of the heat sink. However, over time, dust accumulates on the surface of the heat sink, which acts like a sweater, seriously affecting its heat dissipation efficiency. Regular cleaning is usually required, which is quite troublesome. Wiping and cleaning each heat sink individually also increases the workload for the staff and reduces cleaning efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a gearbox structure with high-efficiency heat exchange, so as to solve the problem mentioned in the background art that the heat sinks on the existing gearboxes need to be wiped and cleaned by the staff one by one, which makes the operation more troublesome and the cleaning efficiency less efficient.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency heat exchange gearbox structure includes: a gearbox body, an assembly platform fixedly disposed on the gearbox body, and heat sinks fixedly disposed on the gearbox body below the assembly platform. A high-efficiency heat dissipation component for a gearbox is mounted on an assembly platform and works in conjunction with heat sinks to dissipate heat from the gearbox body. A wind direction changing component is installed on the gearbox high-efficiency heat dissipation component to change the wind direction so that the wind blows towards both ends of the gearbox body. A heat dissipation component fixing mechanism is installed on the assembly platform and connected to the wind power deflector component. The wind power deflector component drives the wind power deflector component to move, thereby fixing the high-efficiency heat dissipation component of the gearbox. A dust cleaning component is movably connected to a wind direction changing component. The wind direction changing component drives the dust cleaning component to move and clean the dust on the surface of the heat sink.

[0005] Furthermore, the high-efficiency heat dissipation component of the gearbox includes: a fan holder, which is mounted on an assembly platform; A support duct is fixedly installed at the lower end of the assembly platform.

[0006] Furthermore, a matching support is fixedly provided in the fan housing, a motor is fixedly installed on the matching support, and fan blades are installed on the motor.

[0007] Furthermore, the airflow generated by the motor driving the fan blades to rotate enters the supporting air duct; A protruding hood is fixedly installed on the supporting air duct, and a second air blowing channel is opened at the lower end of the protruding hood, through which air is blown towards the heat sink.

[0008] Furthermore, the wind direction changing component includes: a wind-changing movable cover, wherein there are two wind-changing movable covers, which are respectively installed at both ends of the supporting wind duct; Two connecting rotating shafts are symmetrically and movably installed on the supporting air duct and movably connected to the variable air hood. The variable air hood drives the connecting rotating shafts to rotate.

[0009] Furthermore, as the air flows through the supporting duct, it pushes the variable air hood to move, causing the ports at both ends of the supporting duct to be in an open state. Under the action of the variable air hood, the air direction at both ends of the supporting duct is changed so that it blows towards both ends of the gearbox body.

[0010] Furthermore, a connecting top strip is fixedly provided at the upper end of the connecting rotating shaft, and a supporting base plate is fixedly provided at the lower end of the connecting rotating shaft.

[0011] Furthermore, the heat dissipation component fixing mechanism includes: a hollow movable plate, which is movably connected to a connecting top strip, and the hollow movable plate is moved by the connecting top strip; The movable support bar is movably installed on the assembly platform and movably connected to the hollow movable plate, and the movable support bar is moved by the hollow movable plate.

[0012] Furthermore, an upper protruding strip is fixedly provided at the upper end of the hollow movable plate, and a first fixing post is fixedly provided on the upper protruding strip, thereby fixing the fan support cylinder through the first fixing post; A second fixing post is fixedly installed on the movable support bar, and the fan support cylinder is fixed by the second fixing post.

[0013] Furthermore, the dust cleaning assembly includes: a movable support plate, which is movably mounted on a support base plate; The movable cleaning frame is movably mounted on the gearbox body and movably connected to the movable support plate, and the movable cleaning frame is moved by the movable support plate; The T-shaped cleaning strip is inserted into the movable cleaning frame and is used to clean the surface of the heat sink.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. When the fan blades rotate and generate wind, the wind force can push the variable wind cover to move. As the variable wind cover moves, it can drive the connecting rotating shaft to rotate. In turn, the connecting rotating shaft can drive the movable cleaning frame to move. As the movable cleaning frame moves, it can clean the heat sink, ensuring the heat dissipation effect of the heat sink. No manual cleaning is required, which is very convenient and quick.

[0015] 2. When the connecting rotating shaft rotates, it can also drive the hollow movable plate to move. The hollow movable plate can fix the fan bearing cylinder in the first layer. As the hollow movable plate moves, it can drive the movable support bar to move. Under the action of the movable support bar, the fan bearing cylinder can be fixed in the second layer, realizing its multi-point fixation, ensuring the firmness and stability of the fan bearing cylinder installation. When the fan blades are not working, the fan bearing cylinder is in the unlocked state, which facilitates its installation, disassembly, maintenance and repair.

[0016] 3. In addition, when the wind drives the installation sleeve to move, the wind direction at both ends of the support duct changes as the installation sleeve moves, allowing the wind at both ends of the support duct to blow towards both ends of the gearbox body to assist in heat dissipation and further improve the heat dissipation effect of the gearbox body.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a technical solution: like Figure 1 , Figure 2 and Figure 3As shown, a high-efficiency heat exchange gearbox structure includes: a gearbox body 1, a high-efficiency heat dissipation component, a wind direction changing component, a heat dissipation component fixing mechanism, and a dust cleaning component. An assembly platform 11 is welded and fixed onto the gearbox body 1. Heat sinks 18 are integrally cast onto the gearbox body 1 below the assembly platform 11. The high-efficiency heat dissipation component is mounted on the assembly platform 11 and cooperates with the heat sinks 18 to dissipate heat from the gearbox body 1, ensuring the normal operation of the gearbox body 1. The wind direction changing component is mounted on the high-efficiency heat dissipation component and is used to change the wind direction. The change directs the airflow to both ends of the gearbox body 1, enhancing its heat dissipation. The heat dissipation component fixing mechanism is mounted on the mounting platform 11 and connected to the airflow reversing component. The airflow reversing component moves the component to fix the high-efficiency heat dissipation component of the gearbox, ensuring its stability and firmness during operation. The dust cleaning component is movably connected to the airflow reversing component. The airflow reversing component moves the dust cleaning component to clean the dust on the surface of the heat sink 18. This eliminates the need for manual cleaning, saving manpower and improving cleaning efficiency.

[0030] like Figure 2 As shown, an installation insertion cavity 12 is provided on the assembly platform 11, and a first air blowing channel 13 is provided at the bottom of the installation insertion cavity 12. A matching anti-rotation column 14 is symmetrically welded and fixed on the inner bottom surface of the installation insertion cavity 12 by welding process. In addition, a protruding support plate 15 is welded and fixed on the assembly platform 11 by welding process, and a support rod 16 is welded and fixed on the protruding support plate 15 by welding process. Support insertion holes 17 are symmetrically provided at both ends of the assembly platform 11, and an installation support rod 19 is welded and fixed on the gearbox body 1 on the lower side of the assembly platform 11 by welding process.

[0031] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the high-efficiency heat dissipation component of the gearbox includes: a fan holder 2 and a supporting air duct 3. The fan holder 2 is installed on the mounting platform 11. Specifically, the fan holder 2 is inserted into the mounting insertion cavity 12 on the mounting platform 11. The fan holder 2 is limited by the cooperation between the mounting insertion cavity 12 and the fan holder 2.

[0032] The fan bearing 2 has symmetrical anti-rotation mating holes 24 at its lower end. When the fan bearing 2 is inserted into the installation insertion cavity 12, the anti-rotation mating holes 24 are fitted onto the mating anti-rotation post 14. The fan bearing 2 is positioned by the mating of the anti-rotation mating holes 24 and the mating anti-rotation post 14. In addition, a first bearing block 25 is welded and fixed at both ends of the fan bearing 2 by welding process. A first fixing hole 26 is opened on the first bearing block 25. A second bearing block 27 is also welded and fixed on the fan bearing 2 by welding process. A second fixing hole 28 is opened on the second bearing block 27.

[0033] The supporting air duct 3 is welded and fixedly installed on the lower end of the assembly platform 11 by welding process, and an air inlet channel 31 is provided on the upper end of the supporting air duct 3. The air inlet channel 31 is aligned with the first air blowing channel 13. The mounting sleeve 34 is welded and fixed on the upper and lower end faces of the supporting air duct 3 by welding process, and the mounting sleeve 34 is connected to the supporting air duct 3.

[0034] A matching support frame 21 is welded and fixed in the fan support duct 2 by welding process. A motor 22 is fixedly installed on the matching support frame 21 by bolts. A fan blade 23 is installed on the motor 22. The wind force generated by the motor 22 driving the fan blade 23 to rotate enters the supporting fan duct 3 through the first air blowing channel 13 and the air inlet channel 31.

[0035] A protruding shroud 32 is integrally formed and fixed on the side of the support air duct 3 near the gearbox body 1. A second air blowing channel 33 is opened at the lower end of the protruding shroud 32. After the air enters the support air duct 3, it blows towards the heat sink 18 from the second air blowing channel 33, thereby improving the heat dissipation efficiency of the heat sink 18 and ensuring the efficient heat dissipation of the gearbox body 1.

[0036] like Figure 3 , Figure 6 and Figure 8 As shown, the wind direction changing component includes: a wind-changing movable cover 4 and a connecting rotating shaft 5. There are two wind-changing movable covers 4, which are respectively installed at both ends of the supporting wind duct 3 and inserted into the supporting wind duct 3 to seal the ports at their ends. An extension connecting strip 41 is welded and fixed on the wind-changing movable cover 4 by welding process. A supporting vertical strip 42 is integrally formed and fixed on the end of the extension connecting strip 41 away from the wind-changing movable cover 4. A connecting top strip 43 is integrally formed and fixed on the supporting vertical strip 42. A connecting moving column 44 is welded and fixed on the connecting top strip 43 by welding process. The surface of the connecting moving column 44 is smooth and burr-free.

[0037] Two connecting rotating shafts 5 are symmetrically and movably mounted on the supporting air duct 3 and movably connected to the variable air cover 4. The variable air cover 4 drives the connecting rotating shafts 5 to rotate. Specifically, a bearing 51 is sleeved on the connecting rotating shaft 5 and installed in the mounting sleeve 34. The connecting rotating shaft 5 is movably mounted on the supporting air duct 3 through the cooperation of the bearing 51 and the mounting sleeve 34. A connecting mating strip 52 is welded and fixed on the connecting rotating shaft 5. A connecting moving channel 53 is opened on the connecting mating strip 52. The connecting moving column 44 on the connecting top strip 43 is inserted into the connecting moving channel 53 and contacts the inner wall of the connecting moving channel 53. The movable connection between the connecting rotating shaft 5 and the variable air cover 4 is realized through the cooperation of the connecting moving column 44 and the connecting moving channel 53.

[0038] In addition, a sweeping plate 54 is welded and fixed on the connecting rotating shaft 5 by welding process. The sweeping plate 54 is located in the supporting air duct 3. When the air moves in the supporting air duct 3, it will act on the sweeping plate 54 and drive the sweeping plate 54 to rotate, thereby making the connecting rotating shaft 5 rotate more smoothly, and thus facilitating the rotation of the connecting rotating shaft 5 by the variable wind hood 4.

[0039] When air flows in the support duct 3, it pushes the variable air shroud 4 to move to the outside of the support duct 3, so that the ports at both ends of the support duct 3 are in an open state. Under the action of the variable air shroud 4, the air direction at both ends of the support duct 3 is changed so that it blows towards both ends of the gearbox body 1, thereby providing auxiliary heat dissipation for the gearbox body 1.

[0040] A connecting top strip 55 is welded and fixed to the upper end of the connecting rotating shaft 5 by welding process. A first connecting pin 56 is welded and fixed to the end of the connecting top strip 55 away from the connecting rotating shaft 5 by welding process. The surface of the first connecting pin 56 is smooth and burr-free. A supporting base plate 57 is welded and fixed to the lower end of the connecting rotating shaft 5 by welding process. A movable mounting hole 58 is opened on the supporting base plate 57.

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, the heat dissipation component fixing mechanism includes: a hollow movable plate 6 and a movable support bar 7. The hollow movable plate 6 is movably connected to the connecting top bar 55. The hollow movable plate 6 is moved by the connecting top bar 55. Specifically, a connecting groove 61 is provided on the hollow movable plate 6. The inner wall of the connecting groove 61 is smooth and burr-free. The first connecting pin 56 on the connecting top bar 55 is inserted into the connecting groove 61 and contacts the inner wall of the connecting groove 61. The movable connection between the hollow movable plate 6 and the connecting top bar 55 is realized through the cooperation of the first connecting pin 56 and the connecting groove 61.

[0042] Support rods 62 are symmetrically welded to the hollow movable plate 6. The support rods 62 are inserted into the support holes 17. The cooperation between the support rods 62 and the support holes 17 provides support and guidance for the support rods 62, thereby supporting the hollow movable plate 6. A return spring 63 is sleeved on the support rods 62. One end of the return spring 63 is welded to the assembly platform 11, and the other end of the return spring 63 is welded to the hollow movable plate 6.

[0043] The movable support bar 7 is movably installed on the assembly platform 11 and movably connected to the hollow movable plate 6. The hollow movable plate 6 drives the movable support bar 7 to move. Specifically, the movable support bar 7 has a guide hole 71, and a support rod 16 is inserted into the guide hole 71. The cooperation between the guide hole 71 and the support rod 16 realizes the support and limitation of the movable support bar 7. The upper end of the hollow movable plate 6 is integrally formed and fixedly provided with an upper protrusion 64. On both sides of the upper protrusion 64, a matching connecting bar 65 is symmetrically welded and fixed. A movable connecting rod 66 is hinged to the matching connecting bar 65. The other end of the movable connecting rod 66 is hinged to the movable support bar 7. The movable connection between the hollow movable plate 6 and the movable support bar 7 is realized through the movable connecting rod 66.

[0044] A first fixing post 641 is also welded and fixed on the upper protruding strip 64 by welding process. When the fan bearing cylinder 2 is fixed by the first fixing post 641, the first fixing post 641 is inserted into the first fixing hole 26.

[0045] A second fixing post 72 is welded and fixed on the movable support bar 7 by welding process. When the fan support cylinder 2 is fixed by the second fixing post 72, the second fixing post 72 is inserted into the second fixing hole 28.

[0046] like Figure 3 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, the dust cleaning assembly includes: a movable support plate 8, a movable cleaning frame 9, and a T-shaped cleaning strip 94. The movable support plate 8 is movably mounted on the support base plate 57. Specifically, a movable plug rod 81 is welded to the upper end of the movable support plate 8. The movable plug rod 81 is inserted into the movable mounting hole 58. A limiting top block 82 is welded to the upper end of the movable plug rod 81. The limiting top block 82 is located on the upper side of the support base plate 57. The movable support plate 8 is mounted on the support base plate 57 by the cooperation between the movable plug rod 81 and the movable mounting hole 58.

[0047] In addition, an installation channel 83 is provided on the movable support plate 8, and a connecting and mating block 84 is installed on the movable support plate 8. An installation movable rod 85 is welded and fixed on the connecting and mating block 84 by welding process. The installation movable rod 85 is inserted into the installation channel 83. The connecting and mating block 84 is installed on the movable support plate 8 by the cooperation of the installation movable rod 85 and the installation channel 83. A second connecting pin 86 is also welded and fixed on the connecting and mating block 84 by welding process. The surface of the second connecting pin 86 is smooth and burr-free.

[0048] The movable cleaning frame 9 is movably mounted on the gearbox body 1 and movably connected to the movable support plate 8. The movable support plate 8 drives the movable cleaning frame 9 to move. Specifically, the movable cleaning frame 9 has a mounting hole 91, into which a mounting rod 19 is inserted to support the movable cleaning frame 9. A cleaning support strip 92 is welded to the inside of the movable cleaning frame 9. T-shaped channels 93 are opened on the cleaning support strip 92 and at both ends of the movable cleaning frame 9, and T-shaped cleaning strips 94 are inserted into the movable cleaning frame. In the T-shaped channel 93 on the cleaning support strip 92, the T-shaped cleaning strip 94 contacts the surface of the heat sink 18 and cleans the surface of the heat sink 18 through the T-shaped cleaning strip 94. A support connecting strip 95 is also welded and fixed on the movable cleaning frame 9 by welding process. A connecting through hole 96 is inserted into the support connecting strip 95, and a second connecting post 86 is inserted into the connecting through hole 96. The inner wall of the connecting through hole 96 contacts the second connecting post 86. The movable connection between the movable support plate 8 and the movable cleaning frame 9 is realized through the cooperation of the second connecting post 86 and the connecting through hole 96.

[0049] When installing the fan housing 2, it is inserted into the mounting cavity 12, which is used to position and support it.

[0050] When the fan housing 2 is working, the motor 22 drives the fan blades 23 to rotate, and the generated airflow enters the support air duct 3. Under the action of the airflow, the variable air shroud 4 is moved, so that the ports at both ends of the support air duct 3 are in an open state. In this way, the direction of the airflow changes under the action of the variable air shroud 4. The airflow blows from the ports at both ends of the support air duct 3 to the end faces at both ends of the gearbox body 1, and performs air cooling on both ends. At the same time, the airflow also blows from the second air blowing channel 33 to the heat sink 18 to further improve the heat dissipation efficiency of the heat sink 18, thereby ensuring the efficient heat dissipation of the gearbox body 1.

[0051] When the variable air shroud 4 moves, the connecting moving column 44 and the connecting moving channel 53 will drive the connecting rotating shaft 5 to rotate. This, in turn, will drive the hollow movable plate 6 to move towards the assembly platform 11 through the cooperation of the first connecting insert 56 and the connecting slide 61. This will allow the first fixing post 641 on the upper protrusion 64 to be inserted into the first fixing hole 26 to fix the fan bearing 2. As the hollow movable plate 6 moves, the movable connecting rod 66 will drive the movable bearing 7 to move towards the fan bearing 2. This will allow the second fixing post 72 on the movable bearing 7 to be inserted into the second fixing hole 28 to further fix the fan bearing 2, ensuring the stability and firmness of the fan bearing 2 during operation. When the gearbox body 1 is not being cooled, the fan bearing 2 is in an unlocked state, making it easy to install and remove, and thus easy to inspect and maintain.

[0052] As the connecting rotating shaft 5 rotates, it will also drive the movable support plate 8 to rotate synchronously. During the rotation of the movable support plate 8, it will drive the mounting rod 85 to move along the mounting channel 83. Thus, with the rotation of the movable support plate 8, the second connecting pin 86 and the connecting through hole 96 will drive the movable cleaning frame 9 to move away from the gearbox body 1. During the movement, the T-shaped cleaning strip 94 will wipe and clean the surface of the heat sink 18, ensuring the cleanliness of the heat sink 18 surface and thus ensuring the heat dissipation effect of the heat sink 18. Furthermore, as the movable support plate 8 rotates, it will cause the T-shaped cleaning strip 94 to separate from the heat sink 18, thus avoiding the T-shaped cleaning strip 94 from affecting the heat dissipation of the heat sink 18.

[0053] When the gearbox body 1 stops working and the fan housing 2 also stops working, the airflow disappears. Under the action of the return spring 63, the hollow movable plate 6 is reset, which also drives the connecting rotating shaft 5 and the variable air movable cover 4 to reset. As the connecting rotating shaft 5 resets, the movable cleaning frame 9 is also reset, so that the T-shaped cleaning strip 94 contacts the heat sink 18 again. In this way, the fan housing 2 can clean the heat sink 18 every time it works, avoiding the accumulation of dust.

[0054] When the T-shaped cleaning strip 94 needs to be replaced, lift the movable support plate 8 upwards to move it upwards, so that the second connecting pin 86 can be disengaged from the connecting through hole 96. The movable cleaning frame 9 can then be removed from the mounting support rod 19. The T-shaped cleaning strip 94 can be pulled out from the lower end of the movable cleaning frame 9 for replacement, which is very convenient. After replacement, the second connecting pin 86 can be inserted back into the connecting through hole 96.
