Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage transformer coil winding technology, and in particular to a winding and unwinding device for photovoltaic energy storage transformer coils. Background Technology

[0002] Photovoltaic energy storage transformers are the core electrical conversion equipment in photovoltaic energy storage systems. Specifically designed for photovoltaic power generation and energy storage scenarios, they achieve efficient energy conversion, electrical isolation, and quality optimization through the principle of electromagnetic induction, ensuring safe and stable system operation and adapting to grid / energy storage needs. Existing photovoltaic energy storage transformer coil winding devices generally consist of unwinding the coil from a spool and winding the coil back; commonly used unwinding and winding devices have relatively simple structures.

[0003] When releasing the wire, the tension control of the coil is unstable, which can easily lead to the wire being too tight or too loose, resulting in stretching deformation or messy wire arrangement. When retracting the wire, the wire arrangement mechanism is not precise enough, resulting in unevenness between coil layers and gaps, which affects the tightness and insulation performance of the coil. Utility Model Content

[0004] This utility model provides a winding and unwinding device for photovoltaic energy storage transformer coils, which solves the above-mentioned structural and technical problems of unstable tension control of the coil during unwinding and insufficient precision of the winding mechanism during winding.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A winding and unwinding device for a photovoltaic energy storage transformer coil includes a workbench. A spool support mechanism, a tension adjustment mechanism, and a clamping and rotating mechanism are sequentially arranged on the top of the workbench. The tension adjustment mechanism includes a movable platform. A first support is arranged on the top of the movable platform, and two springs are arranged at the bottom of the first support. A downward pressure pulley is arranged between the bottoms of each spring. An upper pressure pulley is arranged on the top of the movable platform near the bottom of the downward pressure pulley. Two first electric telescopic rods are arranged near the center of the top of the movable platform, and an upper pressure roller is arranged on the top of each first electric telescopic rod. A second support is arranged on the top of the movable platform near the upper pressure roller, and two second electric telescopic rods are arranged at the bottom of the second support. A lower top roller is arranged on the bottom of each second electric telescopic rod. A moving mechanism is arranged at the bottom of the movable platform.

[0006] The beneficial effects of this utility model are as follows: the workbench mainly serves to facilitate support and load-bearing; the spool support mechanism facilitates the placement of the spool; the tension adjustment mechanism facilitates the control of the tension of the wire during unwinding; the clamping and rotating mechanism facilitates the rotation of the coil; the moving platform facilitates the support of the first bracket, which in turn supports the spring. The spring, through its elasticity, causes the lower fixed pulley to press downwards, and the lower and upper fixed pulleys fix the direction of the wire's movement. The first electric telescopic rod moves the upper pressure roller upwards, and the second electric telescopic rod under the second bracket moves the lower top roller downwards to press the wire. When the wire needs to move, it generates friction with the upper and lower pressure rollers, which acts as tension to resist the wire's movement. The moving mechanism facilitates the control of the spacing during coil winding, ensuring neat wire winding during take-up.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the moving mechanism includes a nut mounting base, which is disposed at the bottom of the moving platform.

The output shaft of the speed-regulating motor is connected to one end of the lead screw body, and a bearing seat is provided at the other end of the lead screw body.

[0020] Furthermore, the bobbin support mechanism includes a fixed bracket, and the top of the fixed bracket is provided with two rotating round seats, and the top of each rotating round seat is provided with an inlet.

[0021] The advantages of adopting the above-mentioned further solution are: the fixed bracket can easily support the rotating round seat, the interior of the rotating round seat allows the insertion post to be inserted, and the provided insertion port makes it easy to insert the insertion post.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-5The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. Example

[0027] like Figure 1-5 As shown, this utility model discloses a winding and unwinding device for a photovoltaic energy storage transformer coil. It includes a workbench 1. From front to back, the top of the workbench 1 comprises a spool support mechanism 2, a tension adjustment mechanism 3, and a clamping and rotating mechanism 4. The tension adjustment mechanism 3 includes a movable platform 31. A first support 32 is mounted on the top of the movable platform 31. Two springs 33 are mounted on the bottom of the first support 32. A downward-pressing fixed pulley 34 is positioned between the bottoms of each spring 33. An upward-pressing fixed pulley 35 is positioned on the top of the movable platform 31 near the bottom of the downward-pressing fixed pulley 34. The elasticity of the springs 33 allows the downward-pressing fixed pulley 34 to press against the upward-pressing fixed pulley 35. A clamping and rotating mechanism 4 is positioned near the center of the top of the movable platform 31. There are two electric telescopic rods 36, each with an upper pressure roller 37 at its top. A second support 38 is located on the top of the moving platform 31 near the upper pressure roller 37. Two electric telescopic rods 39 are located at the bottom of the second support 38, each with a lower top roller 391 at its bottom. The electric telescopic rods 36 move the upper pressure roller 37 upwards, thus pushing the guide upwards. The electric telescopic rods 39 and lower top rollers 391 squeeze the wire upwards, generating friction on the wire. By increasing the friction, the tension of the wire can be controlled. The moving mechanism 5 facilitates neat wire arrangement. Example

[0028] like Figure 1-5As shown, the moving mechanism 5 includes a nut mounting base 51, which is located at the bottom of the moving table 31. A lead screw nut 52 is installed inside the nut mounting base 51, and a lead screw body 53 is slidably connected inside the lead screw nut 52. A moving groove 54 is opened on the top of the worktable 1, and a sliding groove 55 is opened inside the moving groove 54. A first-speed adjustable motor 56 is installed on the side of the moving groove 54 near the sliding groove 55. The output shaft of the first-speed adjustable motor 56 is connected to one end of the lead screw body 53, and a first-bearing seat 57 is installed at the other end of the lead screw body 53. The first-speed adjustable motor 56 can rotate the lead screw body 53, so that the lead screw nut 52 can move axially along the lead screw body 53. The nut mounting base 51 is located outside the lead screw nut 52. A slider 58 is slidably connected to the top of the sliding groove 55. The top of the slider 58 is connected to the bottom of the nut mounting base 51. The nut mounting base 51 is connected to the slider 58, so that it can move laterally along the direction of the sliding groove 55, and can also move the moving table 31 laterally. The clamping and rotating mechanism 4 includes a U-shaped bracket 41. Two second-grade bearing seats 42 are mounted on the top of the U-shaped bracket 41. A rotating column 43 is rotatably connected to the opposite side of each second-grade bearing seat 42. A mounting plate 44 is mounted on the opposite side of each rotating column 43. A third-grade electric telescopic rod 45 is mounted on the opposite side of each mounting plate 44. A pressing plate 46 is mounted on the opposite side of each third-grade electric telescopic rod 45. One end of one rotating column 43 is connected to a connecting column 47. A first-grade gear 471 is mounted on one side of the connecting column 47. The bottom of the first-grade gear 471 is meshed with a second-grade gear 4. 72. A rotating rod 473 is provided on one side of the second gear 472, and a second speed-regulating motor 474 is provided on one side of the rotating rod 473. A support plate 475 is fixed to the bottom of the second speed-regulating motor 474. The support plate 475 is provided on one side of the U-shaped bracket 41. The second speed-regulating motor 474 drives the rotating rod 473 and the second gear 472 to rotate, which facilitates the rotation of the first gear 471 and the connecting column 47. The connecting column 47 can drive the rotating column 43 and the mounting plate 44 to rotate. The coil clamped by the third electric telescopic rod 45 and the pressing plate 46 will be rotated together. The spool support mechanism 2 includes a fixed bracket 21. The top of the fixed bracket 21 is provided with two rotating seats 22. Each rotating seat 22 has an insertion port 23 on its top. The insertion port 23 allows the insert to be fixed on the seat, and the insert can pass through the inner opening of the spool. This allows the spool to be placed on the rotating seat 22, which allows the insert to rotate. Working principle: When it is necessary to wind the wire on the spool onto the coil of the photovoltaic energy storage transformer, first insert the spool into the socket and fix it. Then, by rotating the inlet 23 on the round seat 22, the socket can be easily inserted. The socket can rotate freely inside. The No. 3 electric telescopic rod 45 can use the extrusion plate 46 to squeeze and clamp the coil on both sides. When the coil needs to be rotated, the wire is wound around the coil through the tension adjustment mechanism 3. The second speed-regulating motor 474 drives the rotating rod 473 and the second gear 472 to rotate, which in turn drives the first gear 471 on the second gear 472 to rotate. The first gear 471 drives the connecting column 47 and the rotating column 43 to rotate. The rotating column 43 is connected to the mounting plate 44 and the third electric telescopic rod 45 through the second bearing seat 42, so that the clamped coil can rotate. When the conductor needs to be tensioned, the conductor passes between the upper pressure fixed pulley 35 and the lower pressure fixed pulley 34. The elasticity of the spring 33 allows the lower pressure fixed pulley 34 to press down and limit the conductor on the upper pressure fixed pulley 35. The conductor then adheres to the upper pressure roller 37 and the lower top roller 391, generating friction between the conductor and the upper pressure roller 37 and the lower top roller 391. The tension of the conductor is controlled by the magnitude of the friction. The first electric telescopic rod 36 and the second electric telescopic rod 39 can adjust the up and down position of the upper pressure roller 37 and the lower top roller 391, thereby squeezing the conductor to generate higher friction, thus preventing the conductor from being too tight or too loose, which could cause stretching deformation or tangled wiring. When it is necessary to make the wound coil neat, the first speed-regulating motor 56 drives the lead screw body 53 to rotate, so that the lead screw nut 52 can move axially along the lead screw body 53. This allows the nut mounting seat 51 on the outside of the lead screw nut 52 to move along the moving table 31. The bottom of the nut mounting seat 51 is connected to the slide groove 55 and the slider 58. This allows the moving table 31 to move laterally linearly along the slide groove 55. This allows the moving table 31 to precisely arrange the wires, preventing unevenness and gaps between coil layers, and also preventing any impact on the coil's tightness and insulation performance.
