[0002] The segmented center shaft quenching device of the photovoltaic tracking system is a device used to enhance the wear resistance and strength of the center shaft of the photovoltaic tracking system. The photovoltaic tracking system maximizes the absorption of light by adjusting the angle of the photovoltaic panels, thereby improving the power generation efficiency. In order to ensure the stability and durability of this system in long-term operation, the center shaft needs to have sufficient mechanical properties, especially anti-wear and anti-fatigue properties.

[0003] When quenching the central shaft, the existing central shaft quenching device usually places the central shaft still inside a quenching box, and performs quenching treatment on the surface of the central shaft by the high temperature inside the quenching box.

[0004] However, there are some shortcomings in the process. Since the central shaft is always in a static state during quenching, it is easy for local parts of the central shaft surface to not be effectively quenched, resulting in uneven quenching of the central shaft surface, making the toughness and hardness of different parts of the central shaft surface inconsistent, which affects the performance of the central shaft to meet the design requirements and affects the quenching effect of the quenching device on the central shaft. For this reason, we proposed a segmented central shaft quenching device for photovoltaic tracking. Utility Model Content

[0038] Example 2

[0039] Based on Example 1, a preferred embodiment of a segmented central shaft quenching device for photovoltaic tracking provided by the utility model is as follows: Figures 1 to 6 As shown: the grinding mechanism 52 includes a horizontal plate 521 fixedly installed at the bottom of the inner wall of the quenching box 3, a water tank 522 is fixedly installed on the top of the horizontal plate 521, a water pump 523 is fixedly installed on the outer wall of the water tank 522, the input end of the water pump 523 is connected to the outer wall of the water tank 522, the output end of the water pump 523 is connected to a connecting pipe 524, the other end of the connecting pipe 524 is connected to a spray head 525, and the outer wall of the connecting pipe 524 is fixedly installed with an L-shaped plate 526, the L-shaped The bottom of the plate 526 is fixedly connected to the top of the water tank 522, the spray head 525 is located below the central axis body 5115, an electric push rod 527 is fixedly installed on the top of the side of the horizontal plate 521, and a U-shaped frame 528 is fixedly installed on the output end of the electric push rod 527. The inner wall of the U-shaped frame 528 is rotatably connected to a rotating rod 529 through a bearing, and a grinding wheel 5210 is fixedly installed on the outer wall of the rotating rod 529. The top of the grinding wheel 5210 is slidably connected to the bottom of the central axis body 5115.

[0040] In this embodiment, by setting up the grinding mechanism 52, during the process of quenching the surface of the central axis body 5115 inside the quenching box 3, the operator can turn on the electric push rod 527 to prompt the U-shaped frame 528 to move upward, so that the top of the grinding wheel 5210 contacts the bottom of the central axis body 5115. During the movement of the quenching box 3, the grinding wheel 5210 will rotate on the outer wall of the rotating rod 529 to achieve uniform grinding of the outer wall of the central axis body 5115. During the grinding process, the operator can turn on the water pump 523 to prompt the water pump 523 to pump the water inside the water tank 522 into the inside of the connecting pipe 524, so that the water is discharged from the spray head 525 and sprayed on the surface of the central axis body 5115, so that the grinding wheel 5210 can grind the surface of the central axis body 5115 more effectively.

[0041] Furthermore, there are four supporting legs 2 , which are equal in size and fixedly installed at the four corners of the bottom of the workbench 1 at equal distances. Through this arrangement, the device can be supported by the four supporting legs 2 .

[0042] Furthermore, one end of the screw rod 515 is fixedly connected to one end of the output shaft 513, and the outer wall of the screw rod 515 is threadedly connected to the inner wall of the sleeve block 516.

[0044] Furthermore, there are two connecting blocks 519 , and the two connecting blocks 519 are symmetrically distributed along the center plane of the limiting column 518 .

[0045] In addition, the outer wall of the screw 5117 is adapted to the inner wall of the cross block 5116, and the bottom of the screw 5117 is rotatably connected to the top of the clamping block 5119.

[0046] Working principle: When the central axis body 5115 needs to be quenched, the operator can place one end of the central axis body 5115 inside the receiving block 5114, and then rotate the adjusting handle 5118 to cause the screw 5117 to rotate. During the rotation of the screw 5117, the clamping block 5119 will move downward, causing the inner wall of the clamping block 5119 to contact the outer wall of the central axis body 5115, so as to clamp and fix the central axis body 5115 that needs to be quenched. Then, by operating the control panel 4, the quenching box 3 is prompted to quench the central axis body 5115 is quenched. In order to prevent uneven quenching of a local position of the center axis body 5115 in the quenching box 3, it is necessary to adjust the quenching position of the center axis body 5115 in the quenching box 3. At this time, the operator can turn on the motor 512 to cause the output shaft 513 to rotate. During the rotation of the output shaft 513, the driving wheel 514 will rotate to cause the driven wheel 5110 to rotate. During the rotation of the driven wheel 5110, the driven shaft 5111 will rotate with the circular plate 5113 to rotate, causing the center axis body 5115 to rotate, so as to achieve the center axis body. The surface of the central axis body 5115 is uniformly quenched. During the rotation of the output shaft 513, the screw rod 515 is rotated with it. The limiting block 517 and the limiting column 518 limit the quenching box 3, which will prompt the sleeve block 516 to move on the outer wall of the screw rod 515, prompting the quenching box 3 to move, so as to achieve uniform quenching of the outer wall of the central axis body 5115, thereby improving the quenching effect of the central axis body 5115. In the process of quenching the surface of the central axis body 5115 inside the quenching box 3, the operator can turn on the electric push rod 527 to prompt the U-shaped frame 528 to move upward. The quenching box 3 moves, causing the top of the grinding wheel 5210 to contact the bottom of the central axis body 5115. During the movement of the quenching box 3, the grinding wheel 5210 will rotate on the outer wall of the rotating rod 529 to achieve uniform grinding of the outer wall of the central axis body 5115. During the grinding process, the operator can turn on the water pump 523 to cause the water pump 523 to pump the water inside the water tank 522 into the connecting pipe 524, so that the water is discharged from the spray head 525 and sprayed on the surface of the central axis body 5115, so that the grinding wheel 5210 can grind the surface of the central axis body 5115 more effectively.
