[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the utility model discloses a rotary reducer of a photovoltaic sun tracking system.

[0030] Example 1

[0031] The utility model provides Figure 1-5 The rotary reducer of a photovoltaic tracking system shown includes a photovoltaic panel 1 and a housing 2 disposed at the lower end of the photovoltaic panel 1. A rotary reducer 3 is disposed within the housing 2. A transmission rod 4 is disposed within the rotary reducer 3. The rod wall of the transmission rod 4 extends through the housing 2 and is connected to the photovoltaic panel 1.

[0032] A mounting bracket 5 is fixedly provided on the top of the rotary reducer 3, and an oil extraction syringe 6 is fixedly provided on the top of the mounting bracket 5. The liquid inlet of the oil extraction syringe 6 is connected with a first oil inlet pipe 7, a second oil inlet pipe 8 and an oil outlet pipe 9. The walls of the first oil inlet pipe 7, the second oil inlet pipe 8 and the oil outlet pipe 9 are fixedly sleeved with an oil one-way valve 12. The ports of the first oil inlet pipe 7 and the second oil inlet pipe 8 are connected with the interior of the outer shell of the rotary reducer 3, and the end of the oil outlet pipe 9 is connected with the rotary reducer 3. The first oil inlet pipe 7, the second oil inlet pipe 8 and the oil outlet pipe 9 are all hoses. The outer wall of the oil extraction syringe 6 is fixedly sleeved with a cooling ring 10, and two symmetrically arranged semiconductor refrigeration plates 11 are fixedly penetrated on the side of the cooling ring 10. The outer wall of the cooling ring 10 is fixedly provided with two symmetrically arranged heat pipes 19, and the heat pipes 19 are sleeved on the outside of the semiconductor refrigeration plates 11, and the ends pass through the casing 2 and extend to the outside.

[0033] When the photovoltaic sun tracking system is in operation, the photovoltaic panel 1 is controlled to rotate by the rotary reducer 3. When the rotary reducer 3 is in use, the oil extraction syringe 6 can be controlled to work, so that the oil extraction syringe 6 is pulled and the lubricating oil inside the rotary reducer 3 is extracted through the first oil inlet pipe 7 and the second oil inlet pipe 8, so that the lubricating oil enters the oil extraction syringe 6. At this time, the cold end of the semiconductor refrigeration plate 11 is located inside the cooling tube 10 and contacts the outer wall of the oil extraction syringe 6, which can cool the lubricating oil inside the oil extraction syringe 6. The cooled lubricating oil re-enters the rotary reducer 3 with the help of the reverse push of the oil extraction syringe 6 and the oil outlet pipe 9, thereby ensuring the internal working temperature of the rotary reducer 3 and improving the operating stability. During the oil flow process, multiple oil one-way valves 12 can allow the oil to circulate according to the fixed oil.

[0034] Example 2

[0035] In order to drive the oil pumping injector 6 to work stably and complete the circulation of lubricating oil, the embodiment 2 is based on the embodiment 1. Figure 2-3 As shown, an oil guide cooling mechanism is provided between the rotary reducer 3 and the oil extraction injector 6, and the oil guide cooling mechanism includes a push plate 13, a through hole is opened inside the push plate 13, and the push plate 13 is sleeved on the rod wall of the transmission rod 4, a push rod 14 is fixed to the outside of the injection rod end of the oil extraction injector 6, and the push plate 13 is matched with the push rod 14. The outer walls of the piston tube end and the injection rod end of the oil extraction injector 6 are respectively fixed with a first mounting plate 15 and a second mounting plate 16, and an elastic telescopic rod 17 is fixed between the first mounting plate 15 and the second mounting plate 16. A locking bolt 18 is threaded through the side of the push plate 13, and the end of the locking bolt 18 passes through the through hole and contacts and cooperates with the transmission rod 4. A rubber ring 20 is fixedly embedded in the inner wall of the through hole, and the rubber ring 20 is sleeved and cooperates with the outer wall of the transmission rod 4.

[0036] When the rotary reducer 3 is running, the transmission rod 4 is driven to rotate accordingly. At this time, under the tightening of the locking bolt 18, the push plate 13 follows the rotation of the transmission rod 4 and pushes the push rod 14. At this time, the oil extraction syringe 6 starts to extract oil, and the elastic telescopic rod 17 is stretched to complete the suction of the lubricating oil. When the lubricating oil is sucked out and cooled, the push plate 13 continues to rotate and separates from the push rod 14. At this time, under the elastic force of the elastic telescopic rod 17, the oil extraction syringe 6 quickly returns to its original position, allowing the lubricating oil to flow outward and completing the circulation of the lubricating oil.

[0037] Example 3

[0038] Example 3 is based on Example 1 in order to perform auxiliary cooling on the rotary reducer 3. Figure 1 and Figure 4 As shown, a fan 21 is fixedly embedded in the side of the casing 2, and the outer cover of the fan 21 is provided with a dustproof net 22. The outer walls of the fan 21 and the dustproof net 22 are fixed with two symmetrically arranged fixing plates 23, and a mounting bolt 24 is screwed between the two fixing plates 23.

[0039] While the rotary reducer 3 is running, the external fan 21 is started, so that the fan 21 sends external cooling air into the casing 2. At the same time, with the setting of the dustproof net 22, the dust inside the cooling air 21 is blocked, which can ensure stable and effective heat dissipation of the rotary reducer 3 and ensure that the operating ring temperature of the rotary reducer 3 is continuously stable.
