[0036] The present invention will be further described below with reference to the accompanying drawings:

[0037] like Figure 1 — Figure 6 As shown, this embodiment provides a photovoltaic ground pile tube shrinking device for shrinking the end of a tube 7. It includes a base 1, a hoisting system 2, a rotation system 3, an internal support system 4, an internal support buffer system 6, and a compression system 5. The hoisting system 2 is installed on the side of the base 1 to hoist the tube 7. The internal support buffer system 6 and the compression system 5 are installed on both ends of the base 1. The internal support system 4 moves inside the tube 7. After the internal support system 4 moves out of the tube 7, the internal support buffer system 6 supports the internal support system 4. The internal support system 4 moves within the tube 7 between the internal support buffer system 6 and the compression system 5 to support the tube 7, ensuring precise dimensions and shape of the tube 7's end.

[0038] The internal support system 4 includes a support motion device 41 and a support device 42, which are fixedly installed together by bolts. The support motion device 41 moves inside the pipe 7. The support device 42 has a cone head 422, which is used to support the inside of the pipe 7 to ensure accurate forming. Several elastic sensing plates 421 are arranged circumferentially on the cone head 422. After the end of the pipe 7 retracts into place, the elastic sensing plates 421 deform, accurately sensing the deformation of the pipe 7 to ensure accurate shape. A limit switch 423 is installed inside the cone head 422. Each end of 423 has a trigger rod 424. Each trigger rod 424 rests on the elastic sensing plate 421. After the elastic sensing plate 421 deforms inward as the end of the tube 7 closes, the elastic sensing plate 421 gradually retracts, causing each trigger rod 424 to retract. The retraction of each trigger rod 424 then triggers the limit switch 423. The limit switch 423 transmits the electrical signal indicating that the forming is in place to the PLC controller. The PLC controller controls the support motion device 41 to retract to the inner support buffer system 6 until the next tube 7 is placed on the rotary system 3. Then, the support motion device 41 drives the support device 42 to enter the tube 7 for forming again.

[0039] To facilitate the forming of the pipe 7, the side of the pipe 7 is preheated using induction heating to reduce forming resistance. To protect the limit switch 423 from overheating and damage, a water tank 8 with an opening is installed on the cone 422 by threaded locking. The water in the water tank 8 is in direct contact with the cone 422 to cool the cone 422 and the limit switch 423.

[0040] Specifically, the hoisting system 2 includes a slewing support rod 21, a translation frame 22, and an electric hoist 23. The slewing support rod 21 is mounted on the base 1. The translation frame 22 is rotatably mounted on the slewing support rod 21 via bearings. The electric hoist 23 is slidably mounted on the translation frame 22 to achieve the lateral movement of the pipe 7. The electric hoist 23 hooks onto the pipe 7, thereby lifting the pipe 7. The rotation of the translation frame 22 drives the pipe 7 to transfer to a different position, so that the pipe 7 is aligned with the slewing system 3.

[0041] Specifically, the slewing system 3 includes a slewing frame 31, a slewing traction motor 32, a slewing friction roller 33, and several idler rollers 34. The slewing frame 31 is swayably mounted on the base 1. A slewing pressure cylinder 35 is provided between the slewing frame 31 and the base 1. The slewing friction roller 33 is rotatably mounted on the slewing frame 31. The slewing pressure cylinder 35 drives the slewing frame 31 to rotate, so that the slewing friction roller 33 presses against the outer circumference of the pipe 7. The slewing traction motor 32 is mounted on the slewing frame 31. The slewing traction motor 32 is connected to the slewing friction roller 33. The idler rollers 34 are rotatably mounted on the base 1. The slewing traction motor 32 drives the slewing friction roller 33 to rotate, thereby realizing the rotation of the pipe 7.

[0042] Specifically, the internal support buffer system 6 includes a buffer frame 61 and a buffer slider 62. The buffer slider 62 is slidably mounted on the base 1, and the buffer frame 61 is mounted on the buffer slider 62. The top of the buffer frame 61 is provided with a semi-circular groove to accommodate the removed internal support system 4. The buffer slider 62 is used to adjust the distance between the buffer frame 61 and the tube 7. The buffer slider 62 can be locked on the base 1 with screws to achieve the adjusted fixation.

[0043] Specifically, the extrusion system 5 includes a forming slider 51, a forming tilting plate 52, and a forming pressure roller 53. The forming pressure roller 53 is rotatably mounted on the forming tilting plate 52. A forming motor 54 is mounted on the forming tilting plate 52. The forming pressure roller 53 is connected to the forming motor 54. The forming tilting plate 52 is swingably mounted on the forming slider 51. A forming drive cylinder 55 is provided between the forming tilting plate 52 and the forming slider 51. The forming slider 51 is slidably mounted on the base 1. The forming drive cylinder 55 drives the forming tilting plate 52 to rotate, so that the forming pressure roller 53 gradually squeezes the rotating tube 7. The end of the tube 7 gradually shrinks towards the support device 42, realizing the clamping and extrusion of the tube 7.

[0044] Specifically, the supporting motion device 41 includes a motion frame 411, three motion swing rods 412, and a motion swing slider 413. The motion swing slider 413 is slidably mounted on the motion frame 411. The motion swing rods 412 are hingedly mounted on the motion frame 411. A connecting rod assembly 414 is hinged between the motion swing slider 413 and the motion swing rods 412. A drive wheel 4121 is provided at the end of the motion swing rod 412. The motion swing slider 413 is driven by a commercially available motor screw structure on the motion frame 411. The slide of the 11 causes each swing arm 412 to swing, causing each drive wheel 4121 to adhere to the inner wall of the pipe 7 and roll along the inner wall of the pipe 7. The support device 42 is installed on the motion frame 411 by bolts. The drive wheel 4121 drives the motion frame 411 to move inside the pipe 7. The drive wheel 4121 is driven by a motor. The motor, which is connected to the drive wheel 4121, is electrically connected to the PLC controller to realize the control of the motor, so that the support device 42 can support and move the position inside the pipe 7.

[0045] Specifically, the support device 42 is provided with three support stabilizing devices 425. Each support stabilizing device 425 includes two support rods that slide against each other. The two support rods are locked together by screws to facilitate the adjustment of the support device 42. The adjusting rods make the support device 42 located on the axis of the pipe 7. Each support stabilizing device 425 is provided with several support wheels to facilitate the rotation of the support device 42. The support stabilizing devices 425 are used to stabilize the position of the support device 42.

[0046] In order to power the aforementioned motors, the motion frame 411 is equipped with wires. These wires are connected to the mains power through a rotary connector. During the process of the inner support system 4 retracting into the inner support buffer system 6, the wires are wound up by a commercially available cable reel. This is existing technology and will not be described in detail here.

[0047] like Figure 6 As shown, after the pipe 7 is narrowed, a small opening will remain. This opening is sealed by welding a tapered component formed from a fan-shaped steel plate to ensure the structural integrity of the pipe 7.

[0048] The tube shrinking process of photovoltaic ground pile tube shrinking equipment includes the following steps:

[0049] S1: Pipe 7 is hoisted onto rotary system 3 using hoisting system 2;

[0050] S2: The internal support system 4 enters the pipe 7 from the internal support buffer system 6;

[0051] S3: The rotary system 3 drives the pipe 7 to rotate, the extrusion system 5 extrudes the end of the pipe 7, and the internal support system 4 supports the pipe 7 inside.

[0052] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
