Description

Technical Field

[0001] The present invention relates to the field of cable manufacturing, and in particular to a cable storage device and method for photovoltaic equipment. Background Art

[0002] With the continuous development of solar energy technology, solar energy or photovoltaics are becoming more and more widely used in daily life. After photovoltaic modules convert solar energy into electrical energy, cables are needed to transmit the energy. After use, these cables need to be stored for easy protection and management. Therefore, the demand for cable storage equipment for photovoltaic equipment arises at the historic moment.

[0003] The cables used in photovoltaic equipment are harder than ordinary cables. When winding the cables, traditional roller-type winding equipment often drags the cables for winding through simple mechanical rotation. During operation, the roller-type cable winding equipment often causes damage to the cable surface, internal conductor breakage, and insulation layer damage due to excessive dragging on the cables, which seriously affects the electrical performance and service life of the cables.

[0004] To sum up, how to solve the problem of cable surface wear, internal conductor breakage and insulation layer damage caused by excessive dragging of the cable during operation of roller-type cable winding equipment has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a cable storage device and method for photovoltaic equipment. Summary of the invention

[0005] To solve the above problems, the present invention provides a cable storage device and method for photovoltaic equipment, which can wind the photovoltaic cable more tightly on the reel, while reducing the damage caused by excessive dragging of the cable by traditional roller-type cable winding equipment.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a cable storage device for photovoltaic equipment, including a base and a controller, the top of the base is fixedly connected to a first support plate and a second support plate, the top of the first support plate is fixedly connected to a first top plate, and the top of the second support plate is fixedly connected to a second top plate; the top of the first top plate and the top of the second top plate are both fixedly connected to a bracket.

[0007] The brackets are all provided with rolling rods, one end of which penetrates through the bracket side wall and rotates with the bracket side wall, and the other end of which is coaxially fixedly connected with a first belt pulley, and a first belt is sleeved between adjacent first belt pulleys.

[0008] A second pulley is coaxially fixedly connected to the rolling rod located above the first top plate.

[0009] A wire reel is arranged on the rolling rod, and the side wall of the wire reel and the rolling rod are in rolling cooperation.

[0010] A driving member is fixedly connected to the top of the base, and an output shaft at one end of the driving member is coaxially fixedly connected to the first bevel gear. An output shaft at the other end of the driving member passes through the side wall of the first support plate and is coaxially fixedly connected to the first limiting gear. The controller is used to control the rotation of the output shaft of the driving member.

[0011] A third support plate is also fixedly connected to the top of the base, and a third pulley is rotatably mounted on the side wall of the third support plate. A second belt is sleeved between the third pulley and the second pulley. A second bevel gear is coaxially fixedly connected to the side wall of the third pulley away from the third support plate, and the first bevel gear and the second bevel gear are meshed.

[0012] A winding assembly for winding the cable onto the cable reel is arranged on the first gear.

[0013] The technical principles of the above scheme are as follows:

[0014] When storing cables for photovoltaic equipment, scattered or bundled cables are wound or placed on the winding assembly, and the output shaft of the driving member is started to rotate by the controller. One end of the driving member drives the first bevel gear to rotate and then drives the second bevel gear to rotate. At this time, the second bevel gear drives the third pulley to rotate, and the third pulley drives the second pulley through the second belt to drive the rolling rod to rotate. The rolling rods drive the first pulley to rotate synchronously through the first belt, and the rotation of the rolling rod can drive the winding reel to rotate; at this time, the first limit gear of the driving member away from one end of the first bevel gear rotates, which can drive the scattered or bundled cables placed on the winding assembly to be wound in a circular circumferential direction along the winding reel. After the winding is completed, the winding reel with the cable wound is removed and stored, so as to realize the rapid storage and arrangement of the cables of the photovoltaic equipment.

[0015] The above scheme has the following beneficial effects:

[0016] 1. The present invention designs a cable storage device for photovoltaic equipment, and utilizes the transmission mechanism of rolling rods, pulleys and belts to achieve smooth and uniform winding of the cable on the reel, thereby avoiding excessive dragging of the cable by traditional drum-type winding equipment, thereby effectively reducing the wear on the cable surface, the breakage of the internal conductor and the damage of the insulation layer, and protecting the electrical performance and service life of the cable.

[0017] 2. In the storage device of the present invention, the cable reel and the rolling rod are rolled together, so that the cable can maintain a small tension during the winding process, further reducing the damage to the cable. At the same time, the controller accurately controls the rotation of the output shaft of the driving member, so that the cable winding speed and tension can be accurately adjusted to ensure the tightness and neatness of the cable winding.

[0018] 3. The cable storage device for photovoltaic equipment of the present invention has a simple structure, is easy to operate and maintain, is suitable for the cable storage needs of photovoltaic equipment of various sizes, and can store bundled or scattered photovoltaic equipment cables, and has broad application prospects and promotion value.

[0019] Furthermore, the winding assembly includes an annular rack with an opening on the annular rack, and a rack cover plate is detachably engaged with the opening; the annular rack is meshed with a first limit gear; a second limit gear is rotatably engaged with the side wall of the first support plate away from the driving member, and the second limit gear is meshed with the annular rack; a circular disk is rotatably engaged with the position of the annular rack near the opening, and a winding drum is coaxially fixedly connected to the circular disk on the side wall away from the annular rack; the first limit gear and the second limit gear are both used to limit the annular rack.

[0020] Beneficial effect: By putting the cable bundle on the winding drum, finding the tap of the cable bundle, and fixing the tap on the inner wall of the cable reel, the first limit gear drives the annular rack to rotate, and the cable can be wound around the cable reel along the circumference of the cable reel as the annular rack rotates. After the winding is completed, the cable reel is taken out of the device for storage. Compared with traditional drum-type cable winding equipment, this winding method can reduce the damage to the cable caused by excessive pulling on the cable.

[0021] Furthermore, a support rod is symmetrically fixedly connected to the top of the first support plate, and the upper side walls of the support rod are rotatably matched with a third limiting gear, and the third limiting gear is meshed with the annular rack; the third limiting gear is used to limit the annular rack.

[0022] Beneficial effect: The third limiting gear can form a stable four-corner support with the first limiting gear and the second limiting gear, thereby limiting the annular rack and preventing the annular rack from shaking up and down or falling off when winding the cable.

[0023] Furthermore, the top of the bracket is symmetrically and fixedly connected with an inclined limiting rod, and the limiting rod is used to limit the winding reel.

[0024] Beneficial effect: The limit rod can limit the cable reel to the middle of the rolling rod when the cable reel is winding the cable, so as to prevent the cable reel from moving left and right on the rolling rod during the winding process, thereby affecting the winding effect.

[0025] Furthermore, a rubber layer is fixedly connected to the side walls of the rolling rod.

[0026] Beneficial effect: The design of the rubber layer increases the friction between the rolling rod and the winding reel, reducing the slippage of the winding reel during the winding process and affecting the winding effect.

[0027] Furthermore, a cable buckle is fixedly connected to the inner wall of the cable reel.

[0028] Beneficial effect: before winding the cable on the reel, the cable tap is pulled out and clamped into the cable buckle, so that the cable can fall off due to the rotation of the annular rack at the beginning of winding, which facilitates the cable to continue winding.

[0029] Furthermore, a plurality of guide grooves are formed on the outer side wall of the cable reel along its circumference.

[0030] Benefits: When the cable is wound on the reel, it will be arranged along the path of the guide groove, which helps to ensure that the cable remains evenly distributed during the winding process and avoids local overcrowding or looseness. In addition, the guide groove can also reduce the friction between the cable and the reel, extending the service life of the cable.

[0031] Furthermore, the cable buckle is made of rubber.

[0032] Beneficial effect: The rubber material is an elastically deformable structure, so that when the cable is fixed on the cable reel, the cable buckle can adapt to cables of different diameters through elastic deformation, ensuring that the cable is firmly fixed without slipping or loosening.

[0033] Furthermore, a pressure sensor is fixedly connected to the outer wall of the cable reel, and the controller is used to receive the pressure signal of the cable on the cable reel sent by the pressure sensor, and control the output shaft of the driving member to change the rotation speed based on the pressure signal.

[0034] Beneficial effect: By setting up the pressure sensor, the pressure exerted on the cable reel during the winding process can be monitored in real time. When the pressure exceeds the preset threshold, the controller will receive the corresponding pressure signal and adjust the output shaft speed of the drive component accordingly, thereby slowing down the winding speed of the cable, reducing the tension on the cable, and preventing the cable from being damaged due to excessive tension.

[0035] Furthermore, a photovoltaic device cable storage method is based on the photovoltaic device cable storage device, and includes the following steps:

[0036] Step 1, preparation stage: manually move the annular rack so that the opening of the annular rack faces upward, and remove the rack cover; place the blank cable reel on the rolling rod, and fix it in the middle position of the rolling rod through the limit rod, and re-engage the rack cover in the opening of the annular rack.

[0037] Step 2: Cable preparation: put the bundled cable on the winding drum, and use one end of the cable as a tap; pass the cable tap through the cable buckle and fix it on the inner wall of the reel.

[0038] Step 3, start the equipment: start the output shaft of the driving member to rotate through the controller.

[0039] Step 4: Cable winding: The winding drum revolves around the cable drum, and the cable drum rotates and winds the cable around the cable drum.

[0040] Step 5: Cable storage: When the cable is completely wound onto the cable reel, operate the controller to turn off the drive, remove the rack cover, take out the cable reel with the cable, attach a label, and put the cable reel with the cable into the warehouse for storage.

[0041] Beneficial effects: The cable storage method for photovoltaic equipment provided by the present invention realizes the rapid and uniform winding of cables through automated equipment, which greatly improves work efficiency and reduces labor costs compared with traditional manual storage; at the same time, it also avoids excessive dragging of cables by traditional roller-type winding equipment, effectively reduces the wear on the cable surface, the breakage of the internal conductor and the damage to the insulation layer, thereby protecting the electrical performance and service life of the cable.

[0042] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Embodiment 1:

[0052] As attached Figure 1-Figure 6 As shown: A cable storage device for photovoltaic equipment includes a base 1 and a controller. The top of the base 1 is fixedly connected to a first support plate 2 and a second support plate 3 by bolts, the top of the first support plate 2 is fixedly connected to a first top plate 4 by bolts, and the top of the second support plate 3 is fixedly connected to a second top plate 5 by bolts; the top of the first top plate 4 and the top of the second top plate 5 are both fixedly connected to a bracket 6 by bolts.

[0053] The brackets 6 are each provided with a rolling rod 7, one end of which passes through the side wall of the bracket 6 and rotates with the side wall of the bracket 6, and the other end of the rolling rod 7 is coaxially fixedly connected to the first pulley 8 by bolts, and a first belt 9 is sleeved between adjacent first pulleys 8.

[0054] A second pulley 10 is coaxially fixedly connected to the rolling rod 7 located above the first top plate 4 via bolts.

[0055] A wire reel 11 is provided on the rolling rod 7, and the side wall of the wire reel 11 and the rolling rod 7 are in rolling cooperation.

[0056] A driving member 12 is fixedly connected to the top of the base 1 by bolts, and an output shaft at one end of the driving member 12 is coaxially fixedly connected to a first bevel gear 13 by bolts, and an output shaft at the other end of the driving member 12 passes through the side wall of the first support plate 2 and is coaxially fixedly connected to a first limit gear 14 by bolts. The controller is used to control the rotation of the output shaft of the driving member 12.

[0057] A third support plate 15 is also fixedly connected to the top of the base 1 by bolts, and a third pulley 16 is rotatably fitted on the side wall of the third support plate 15. A second belt 17 is sleeved between the third pulley 16 and the second pulley 10. A second bevel gear 18 is coaxially fixedly connected to the side wall of the third pulley 16 away from the third support plate 15 by bolts, and the first bevel gear 13 and the second bevel gear 18 are meshed.

[0058] The first limiting gear 14 is provided with a winding assembly for winding the cable onto the cable reel 11 .

[0059] The winding assembly includes an annular rack 19, which has an opening, and a rack cover 20 is detachably engaged with the opening; the annular rack 19 is meshed with the first limit gear 14; the first support plate 2 is rotatably engaged with a second limit gear 21 on a side wall away from the driving member 12, and the second limit gear 21 is meshed with the annular rack 19; the annular rack 19 is rotatably engaged with a circular disk 22 near the opening, and a winding drum 23 is coaxially and integrally formed on the side wall of the circular disk 22 away from the annular rack 19; the first limit gear 14 and the second limit gear 21 are both used to limit the annular rack 19.

[0060] The top of the first support plate 2 is also symmetrically connected with a support rod 24 by bolts. The upper side walls of the support rod 24 are rotatably matched with a third limiting gear 25, and the third limiting gear 25 is meshed with the annular rack 19; the third limiting gear 25 is used to limit the annular rack 19.

[0061] The top of the bracket 6 is symmetrical and integrally formed with an inclined limiting rod 26 , and the limiting rod 26 is used to limit the winding reel 11 .

[0062] The side walls of the rolling rod 7 are fixedly bonded with a rubber layer.

[0063] A cable buckle 27 is fixedly connected to the inner wall of the cable reel 11 by means of screws.

[0064] The photovoltaic equipment cable storage method is based on the photovoltaic equipment cable storage device and includes the following steps:

[0065] Step 1, preparation stage: manually move the annular rack 19 so that the opening of the annular rack 19 faces upward, and remove the rack cover 20; place the blank winding reel 11 on the rolling rod 7, and fix it in the middle position of the rolling rod 7 through the limit rod 26, and re-engage the rack cover 20 in the opening of the annular rack 19.

[0066] Step 2, cable preparation: put the bundled cable on the winding drum 23, and use one end of the cable as a tap; pass the tap of the cable through the cable buckle 27 and fix it on the inner wall of the winding drum 11.

[0067] Step 3, start the device: start the output shaft of the driving member 12 to rotate through the controller.

[0068] Step 4: Cable winding: The winding drum 23 revolves around the cable reel 11 in a circumferential direction, and the cable reel 11 rolls and rotates, so that the cable is wound around the cable reel 11 in a circular direction.

[0069] Step 5, cable storage: When the cable is completely wound onto the cable reel 11, operate the controller to close the drive member 12, remove the rack cover 20, take out the cable reel 11 with the cable wound on it, attach a label, and put the cable reel 11 with the cable wound on it into the warehouse for storage.

[0070] The specific implementation process is as follows:

[0071] by Figure 1 and Figure 6 For example, when storing the cables of the photovoltaic equipment, the rack cover 20 is removed from the opening of the annular rack 19 and the opening of the annular rack 19 is manually rotated upward, the cable reel 11 is inserted from the opening of the annular rack 19 and placed on the rolling rod 7, and the cable reel 11 is restricted to the middle of the rolling rod 7 by the limit rod 26. Then, the rack cover 20 is engaged with the opening of the annular rack 19 to start the cable storage operation.

[0072] Put the bundled photovoltaic equipment cables to be stored onto the winding drum 23, find the cable tap, and insert the tap into the cable buckle 27 to fix it on the inner side of the winding drum 11. At this time, the controller controls the output shaft of the driving member 12 to rotate counterclockwise; in this embodiment, the driving member 12 is a double-headed motor; the rotation of the output shaft of the double-headed motor can drive the first bevel gear 13 and the first limit gear 14 to rotate counterclockwise at the same time.

[0073] by Figure 1 and Figure 3 For example, since the first bevel gear 13 and the second bevel gear 18 are meshed, the second bevel gear 18 will also rotate synchronously, thereby driving the third pulley 16 coaxially connected to it by bolts to rotate. The third pulley 16 is connected to the second pulley 10 on the rolling rod 7 located above the first top plate 4 through the second belt 17. Therefore, when the third pulley 16 rotates, it will drive the second pulley 10 and the rolling rod 7 coaxially connected thereto to rotate. At the same time, since the first belt 9 is sleeved between adjacent first pulleys 8, when one of the rolling rods 7 rotates, the adjacent rolling rods 7 will be driven to rotate synchronously through the first belt 9.

[0074] by Figure 1 , Figure 2 and Figure 4For example, as the rolling rod 7 rotates, the cable reel 11 is also driven to roll. While the cable reel 11 rolls, since the first limit gear 14 is meshed with the annular rack 19, the first limit gear 14 can limit and transmit the annular rack 19. The annular rack 19 will rotate after receiving the rotational driving force of the first limit gear 14. At the same time, since the second limit gear 21 and the third limit gear 25 are also meshed with the annular rack 19, the third limit gear 25 can form a stable four-corner support with the first limit gear 14 and the second limit gear 21, thereby limiting the annular rack 19 and preventing the annular rack 19 from shaking and falling off during the rotation process.

[0075] by Figure 1 , Figure 3 and Figure 4 For example, when the annular rack 19 rotates clockwise, the circular disk 22 rotates and cooperates with the side wall of the annular rack 19. At this time, the annular rack 19 can drive the circular disk 22 and then drive the winding drum 23 to revolve clockwise around the cable reel 11 during the clockwise rotation. Since the cable tap and the inner wall of the cable reel 11 are fixedly connected by the cable clip 27, at this time, under the action of the revolution of the winding drum 23 and the clockwise rolling of the cable reel 11, the cable wrapped around the winding drum 23 can be wound around the cable reel 11 in a circular circumferential manner, thereby achieving smooth and uniform winding of the cable on the cable reel 11.

[0076] by Figure 1 and Figure 6 For example, when the opening of the annular rack 19 rotates to the point where it meshes with the first limit gear 14, the teeth on the side wall of the rack cover 20 on the annular rack 19 can continue to mesh with the first limit gear 14, so that the first limit gear 14 can continue to drive the annular rack 19 to rotate, preventing the annular rack 19 from getting stuck during rotation.

[0077] by Figure 5 and Figure 6 For example, after the winding is completed, the rack cover 20 on the annular rack 19 is removed, the cable reel 11 is taken out from the opening of the annular rack 19, and a corresponding label is attached to the cable reel 11, and then the cable reel 11 is stored.

[0078] The winding drum 23 is flexible and efficient in winding a single bundle of cables onto the cable reel 11. Specifically, after winding a cable, another bundle of cables with different wire diameters can be directly sleeved onto the winding drum 23 without replacing the cable reel 11, and continue to be wound onto the same cable reel 11. This design realizes the continuous storage operation of multiple bundles of cables and improves work efficiency.

[0079] In addition, the device is also suitable for storing scattered single cables. When storing scattered cables, the user only needs to manually wind the cable on the winding drum 23, and then start the device to smoothly and evenly wind the wound cable onto the reel 11. After completing the storage of scattered cables once, the device can continue to receive and store other scattered cables, further improving the practicality and flexibility of the device.

[0080] The photovoltaic equipment cable storage device of the present invention can not only continuously store multiple bundles of cables, but also efficiently handle scattered single cables, thereby meeting the cable storage needs in different scenarios. At the same time, compared with the traditional roller-type cable winding device, the winding method of the present invention can keep the cable with a smaller tension during the winding process, further reducing the damage to the cable, and can reduce the damage to the cable caused by excessive pulling on the cable.

[0081] Embodiment 2:

[0082] As attached Figure 5 As shown, the difference from the first embodiment is that a plurality of guide grooves are formed on the outer wall of the cable reel 11 along its circumference.

[0083] The specific implementation process is as follows:

[0084] When the cable is wound on the cable reel 11, it will be arranged along the path of the guide groove, which helps to ensure that the cable remains evenly distributed during the winding process and avoids local overcrowding or looseness. In addition, the guide groove can also reduce the friction between the cable and the cable reel 11 and extend the service life of the cable.

[0085] Embodiment 3:

[0086] As attached Figure 5 As shown, the difference from Embodiment 2 is that the cable buckle 27 is made of rubber.

[0087] The specific implementation process is as follows:

[0088] The rubber material is an elastically deformable structure, so that when the cable is fixed on the cable reel 11, the cable buckle 27 can adapt to cables of different diameters through elastic deformation, ensuring that the cable is firmly fixed and will not slip or loosen.

[0089] Embodiment 4:

[0090] As attached Figure 5 As shown, the difference from Example 3 is that a pressure sensor is fixedly connected to the outer wall of the cable reel 11 by screws, and the controller is used to receive the pressure signal of the cable on the cable reel sent by the pressure sensor, and control the output shaft of the driving member 12 to change the rotation speed based on the pressure signal.

[0091] The specific implementation process is as follows:

[0092] By setting the pressure sensor, the controller can monitor in real time the pressure exerted by the cable on the cable reel 11 during the winding process. When the pressure exceeds the preset threshold, the controller will receive the corresponding pressure signal and adjust the output shaft speed of the double-headed motor accordingly. For example, the pressure threshold is set in advance. When the pressure exerted by the cable on the cable reel 11 exceeds the threshold, the controller sends a control signal to control the output shaft of the double-headed motor to slow down the speed, thereby slowing down the rotation speed of the annular rack 19, thereby reducing the tension on the cable and preventing the cable from being damaged due to excessive tension.

[0093] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
