Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically to a synchronous balanced drive device. Background Technology

[0002] Photovoltaic solar panels are prone to accumulating dust on their surface during daily use. This dust accumulation can not only reduce power generation efficiency but also damage the photovoltaic modules in severe cases. Therefore, regular cleaning is a necessary measure to maintain the normal operation of photovoltaic modules.

[0003] For example, Chinese patent CN207150522U discloses a solar panel cleaning device for photovoltaic power generation, which includes a bracket and a water tank. The bracket is equipped with a solar panel, and the front side of the bracket has bearing seats symmetrically arranged at both the top and bottom. A threaded rod is arranged between the symmetrical bearing seats. A motor that drives the threaded rod is arranged at the right end of the bracket, and a cleaning box is arranged on the symmetrical threaded rod. This device can drive the screw to move the cleaning box left and right to brush the solar panel, and the cleaning effect is good.

[0004] However, the threaded rod of the above-mentioned equipment will wear during use, and due to uneven force, the wear on both sides cannot be made consistent, which will affect the operation of the entire equipment.

[0005] Based on this, the present invention designs a synchronous balanced drive device to solve the above problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A synchronous balancing drive device includes a frame connected to the upper end of a support 1. The frame consists of a housing 5 and side plates 6 fixedly installed at both ends of the housing 5. It also includes pull cables 3, a balancing driven mechanism 7, and a rotating shaft 8. The balancing driven mechanism 7 includes a limiting driven component 71, a tensioning fixed component 72, and a balancing roller assembly 73. Two sets of pull cables 3, a motor 4, side plates 6, limiting driven components 71, tensioning fixed components 72, and guide wheels 9 are symmetrically distributed about the front and rear of the support 1. The motor 4 is fixedly connected to the outer wall of the support 1, and the output end of the motor 4 is fixedly connected to the guide wheels 9. The guide wheel 9 is used to pull the pull cable 3 to rotate. The upper limit follower component 71 and the lower tensioning and fixing component 72 are connected to the outer wall of the side plate 6. The balance roller component 73 is connected to the outer shell 5 and the side plate 6 respectively. The two ends of the rotating shaft 8 located between the side plates 6 are rotatably connected to the side plates 6 respectively. The rotating shaft 8 is connected to the limit follower component 71. One end of the pull cable 3 is fixedly connected to the outer wall of the side plate 6 away from the motor 4. The other end of the pull cable 3 passes through the other outer wall of the side plate 6 and is connected to the tensioning and fixing component 72. The middle part of the pull cable 3 passes through the limit follower component 71. The pull cable 3 is wound around the guide wheel 9.

[0030] The pull line 3 is made of steel wire rope, with a high mechanical angle and strong wear resistance.

[0031] In this invention, the starting motor 4 rotates the guide wheel 9, which pulls the pull wire 3. The two ends of the pull wire 3 are fixed to the side plate 6 and the tensioning assembly 72, respectively. Therefore, under the limiting action of the limiting follower assembly 71, the pull wire 3 drives the side plate 6 to move and the rotating shaft 8 to rotate. The movement of the side plate 6 drives the outer shell 5 and the balance roller assembly 73 to move, thereby realizing the synchronous drive of the motor 4 and the pull wire 3 to move the outer shell 5 left and right. This drive can meet the requirement of balanced movement at both ends without adjustment during movement.

[0032] In some embodiments, please refer to the accompanying drawings. Figures 2-5 The limiting follower assembly 71 includes a central rotating column 711, a side plate limiting column, and a starting point limiting column 715. The central rotating column 711 is rotatably connected to the outer surface of the side plate 6. The starting point limiting column 715 is located to the right of the central rotating column 711 and is rotatably connected to the front end surface of the bracket 1. The side plate limiting column is located around the central rotating column 711 and is connected to the outer wall of the side plate 6.

[0033] Both the central rotating column 711 and the starting point limiting column 715 are cylindrical structures that are wide at both ends and narrow in the middle. The narrow part in the middle is a limiting channel, which is used to guide and restrict the pull line 3 from passing through.

[0034] like Figure 4 As shown, the side plate limiting posts include a first longitudinal limiting post 712, a second longitudinal limiting post 713, and a transverse limiting post 714, which are fixedly connected to the outer wall of the side plate 6. All three are located above the central rotating post 711 and are distributed from left to right.

[0035] The first longitudinal limiting post 712, the second longitudinal limiting post 713, and the transverse limiting post 714 are fixedly connected to the side plate 6 by bolts and nuts respectively.

[0036] The first longitudinal limiting post 712, the second longitudinal limiting post 713, and the transverse limiting post 714 are all cylindrical structures that are wide at both ends and narrow in the middle. The narrow part in the middle is a limiting channel, which is used to guide and restrict the pull wire 3 from passing through.

[0037] The portion of the pull line 3 between the central rotating post 711 and the transverse limiting post 714 is misaligned with the portion of the pull line 3 between the central rotating post 711 and the second longitudinal limiting post 713.

[0038] like Figure 3 and Figure 5As shown, the tensioning fixing assembly 72 includes a tensioning shaft 721, a spring 722, a ratchet 723, a pawl 724, and a fixing block 725. The lower end of the fixing block 725 is fixedly connected to the upper surface of the side plate 6 on the side away from each other. A through hole for accommodating the movement of the pull wire 3 is opened at the left end of the fixing block 725. A through receiving groove is opened inside the fixing block 725, which communicates with the through hole. The tensioning shaft 721 is located inside the receiving groove. 721 is rotatably connected to the fixed block 725. The tensioning shaft 721 is fixedly connected to the pull wire 3. The front end of the tensioning shaft 721 is fixedly connected to the ratchet 723. The spring 722 is located below the pawl 724. One end of the spring 722 is fixedly connected to the fixed block 725, and the other end of the spring 722 is fixedly connected to the pawl 724. The spring 722 is used to tighten the pawl 724. The pawl 724 is rotatably connected to the fixed block 725, and the pawl 724 is engaged with the ratchet 723.

[0039] The front end of the ratchet 723 is fixedly connected to a rotating handle, which is covered with a silicone layer to increase friction and facilitate gripping and rotation.

[0040] The tensioning shaft 721 is a cylindrical structure that is wide at both ends and narrow in the middle. The narrow part is the winding compartment, which is used to store the pull wire 3.

[0041] The pull line 3 is sequentially wound around the outside of the starting limit post 715, the outside of the transverse limit post 714, the outside of the central rotating post 711, the upper side of the second longitudinal limit post 713, the lower side of the first longitudinal limit post 712, and the outside of the guide wheel 9 from the right end, and the pull line 3 is wound around the central rotating post 711 several times.

[0042] like Figure 3 As shown, the balancing roller assembly 73 includes end rollers and middle rollers 733. The two sets of end rollers are symmetrically distributed about the outer shell 5. The end rollers are connected to the side plate 6. The two sets of middle rollers 733 are rotatably connected to the left and right side walls of the middle part of the outer shell 5, respectively. The lower end of the middle roller 733 is rolledly connected to the upper surface of the bracket 1.

[0043] like Figure 3 As shown, the end rollers include top rollers 731 and side rollers 732. The two top rollers 731 are rotatably connected to the side plate 6 near the middle roller 733. The lower end of the top rollers 731 is rolledly connected to the upper surface of the bracket 1. The two side rollers 732 are rotatably connected to the lower surface of the side plate 6. The side rollers 732 are rolledly connected to the side of the bracket 1.

[0044] When cleaning photovoltaic module 2, a cleaning brush can be fixedly connected to the rotating shaft 8, and the cleaning brush rotates synchronously with the rotating shaft 8 to clean photovoltaic module 2.

[0045] In this invention, the rotating ratchet 723 engages, causing the pull wire 3 to wind into the winding chamber of the tensioning shaft 721. Once the pull wire 3 is tightened, the rotation of the ratchet stops, and the pawl 724 is tightened by the spring 722. The resetting action of the ratchet 723 is blocked by the latching pawl 724, meaning that the ratchet 723 cannot rotate under the limiting action of the pawl 724. Through the cooperation of the tensioning shaft 721, the spring 722, the ratchet 723, and the pawl 724, the pull wire 3 is tightened, and the drive device can operate in a balanced manner.

[0046] The motor 4 is started, and the output end of the motor 4 drives the guide wheel 9 to rotate, pulling the pull cable 3. The pull cable 3, with the cooperation of the first longitudinal limit post 712, the second longitudinal limit post 713, the transverse limit post 714 and the starting limit post 715, drives the central rotating column 711 to rotate. The rotation of the central rotating column 711 drives the outer shell 5 and the side plate 6 to move. The rotation of the central rotating column 711 drives the rotating shaft 8 to rotate. By installing cleaning bristles on the rotating shaft 8, the photovoltaic module 2 can be cleaned synchronously with the translational movement of the outer shell 5. The top roller 731, the side roller 732 and the middle roller 733 roll on the bracket 1, which also makes the outer shell 5 and the side plate 6 move left and right only in the horizontal direction. This realizes that the outer shell 5 is driven to move left and right synchronously by the motor 4 and the pull cable 3. This drive can meet the requirements of balanced movement at both ends without adjustment during movement.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
