[0013] In an optional embodiment, a V-shaped groove is provided at the upper end of the bracket away from the driving disk, and a support bearing group is provided at the bottom of the V-shaped groove. One end of the reel shaft is placed on the support bearing group to facilitate placing the reel shaft on the bracket, thereby further improving the convenience of installing or disassembling the reel frame.

[0014] In an optional embodiment, the bracket is provided with a limit member, the limit member is detachably connected to the bracket, and the limit member is used to limit the reel shaft within the V-shaped groove to prevent the reel shaft from slipping off the bracket during rotation.

[0015] In an optional embodiment, the limiting member is a latch pin, and both ends of the limiting member in the length direction are inserted into the side walls corresponding to the V-shaped slot to facilitate quick installation and removal of the limiting member.

[0028] At the same time, the terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances. Example

[0029] Combination Figure 1 The present embodiment provides a constant tension steel strand retracting and releasing device, comprising: a bracket 10; a reel frame 20, provided with a reel shaft 21, the reel shaft 21 being rotatable along its own axis and arranged on the bracket 10; a drive disk 30, detachably connected to the reel frame 20, a through hole being provided in the middle for the reel shaft 21 to pass through, for transmission connection with a rotary driver 40.

[0030] It should be noted that the present embodiment further includes a rotation driver 40 , which is fixed to the bracket 10 , and the output end of the rotation driver 40 is detachably connected to the drive disk 30 , so as to directly drive the reel frame 20 to rotate through the rotation driver 40 .

[0031] The rotary driver 40 includes an output shaft 41, and the output shaft 41 is detachably connected to the driving disk 30, so as to facilitate the transmission connection between the rotary driver 40 and the driving disk 30. The driving disk 30 is usually connected to the output shaft 41 by bolts.

[0032] Combination Figure 2One end of the output shaft 41 connected to the driving disk 30 is sleeved outside one end of the reel shaft 21, and the output shaft 41 and the reel shaft 21 can rotate relative to each other to facilitate the installation of the reel shaft 21.

[0033] Combination Figure 3 In this embodiment, the driving disc 30 is provided with a driving protrusion 31, and the driving protrusion 31 is inserted into the gap between the spokes 22 of the reel frame 20, so that the output torque of the rotary driver 40 is transmitted by the driving protrusion 31 contacting the spokes 22, so that the driving protrusion 31 only needs to be inserted into the gap between the spokes 22, which facilitates the quick connection and disassembly of the driving disc 30 and the reel frame 20. In this embodiment, the driving protrusion 31 is a pin shaft vertically inserted into the driving disc 30.

[0034] Generally speaking, the driving disc 30 is provided with two driving protrusions 31 , and the two driving protrusions 31 are arranged on both sides of the length direction of the reel shaft 21 to ensure the stability of the torque transmitted by the driving disc 30 .

[0035] On this basis, a V-shaped guide groove 32 is provided in the middle of the driving disk 30. The V-shaped guide groove 32 is provided through the driving disk 30 along the thickness direction of the driving disk 30. The V-shaped guide groove 32 is connected to the through hole, and the reel shaft 21 can slide into the through hole through the V-shaped guide groove 32, so as to facilitate the reel drum to be clamped in the driving disk 30, thereby further improving the convenience of connecting or disassembling the driving disk 30 and the reel drum.

[0036] Combination Figure 4 A V-shaped groove 11 is provided at the upper end of the side of the bracket 10 away from the driving disk 30, and a support bearing group 13 is provided at the bottom of the V-shaped groove 11. One end of the reel shaft 21 is placed on the support bearing group 13 to facilitate the placement of the reel shaft 21 on the bracket 10, thereby further improving the convenience of installing or disassembling the reel frame 20.

[0037] It is understandable that the bracket 10 is provided with a limit member 12, and the limit member 12 is detachably connected to the bracket 10. The limit member 12 is used to limit the reel shaft 21 in the V-shaped groove 11 to prevent the reel shaft from slipping off the bracket 10 during rotation.

[0038] In this embodiment, the limiting member 12 is a latch pin, and both ends of the limiting member 12 in the length direction are inserted into the side walls corresponding to the V-shaped slot 11 to facilitate the rapid installation and removal of the limiting member 12 .

[0039] It should be noted that the constant tension steel strand retracting and releasing device provided by the utility model has a reel frame 20 which is rotatable along its own axis through a reel shaft 21 and is mounted on a bracket 10, and the drive disk 30 is detachably connected to the reel frame 20 so that the reel shaft 21 only plays a supporting role, and the entire reel frame 20 rotates by driving the drive disk 30 to rotate through the rotating driver 40.

[0040] During normal use, the reel frame 20 is driven to rotate directly through the rotary driver 40, and the tension of the steel strand is kept constant. Since the reel drum only plays a supporting role, when the reel frame 20 needs to be replaced, the latch is pulled out, and the connection between the drive disc 30 and the reel frame 20 is disconnected. Specifically, in the process of replacing the wire reel, it is only necessary to pull out the latch (limiting member 12), and slightly lift the reel shaft 21, and then pull it out of the reel 20. The reel frame 20 can be hoisted and replaced by removing the drive column (i.e., the driving protrusion 31 mentioned in the text). After the new wire reel is in place, the reel 21 is inserted, and the latch (limiting member 12) is reinserted to complete the replacement of the new wire reel. Therefore, the utility model can quickly replace the steel strand reel to shorten the time for replacing the steel strand and meet the production requirements of the automated installation of flexible bracket photovoltaic modules.

[0041] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
