TECHNICAL FIELD

[0001] The utility model relates to the field of rotary limiting spring, especially relates to a rotary limiting assembly for flexible bridge connection. BACKGROUND

[0002] In the structure of large photovoltaic power station, for example, between multiple photovoltaic module arrays, a spacing is generally provided. In order to reduce the number of cleaning robots and save costs, a method of connecting photovoltaic module arrays by a bridge is usually adopted to provide a passing condition for the robot, so that one cleaning robot can clean multiple array photovoltaic modules.

[0003] For a flat single-axis tracking support, adjacent photovoltaic modules or photovoltaic module arrays are connected together by a bridge, and after the photovoltaic cleaning robot completes the cleaning work on a single photovoltaic module array, it can run to another photovoltaic module array through the bridge, thereby realizing continuous cleaning work and improving the utilization efficiency of the photovoltaic cleaning robot. The bridge generally has two forms: a fixed bridge and a rotatable bridge. The rotatable bridge is composed of a sleeve assembly and a bridge connection rotating piece applied to adjacent photovoltaic modules at both ends. The sleeve assembly can stretch and contract according to the rotation of the photovoltaic module in the tracking support, so that adjacent photovoltaic modules or photovoltaic module arrays are always connected. The sleeve assembly is composed of multiple inner and outer sleeves and has a square tube or a circular tube shape. The bridge connection rotating piece is composed of two C-shaped steel sheets. One C-shaped steel sheet is fixed on the support square tube as a fixed piece. The other C-shaped steel sheet provides a rotating function when the tracking support rotates, but when the bridge rotates, the relative rotation of the two C-shaped connecting pieces will have a dead point. At this time, if the support continues to track and run, the C-shaped piece will be torn and broken, thereby causing structural failure. SUMMARY

The limiting spring is arranged on the first C-shaped connecting piece and is used for blocking the second C-shaped connecting piece to prevent the extension direction of the first through slot after rotation from being parallel to the extension direction of the second through slot.

[0006] Different from the prior art, the above technical scheme avoids that the rotating part rotates to the dead point position in the extension and retraction process of the flexible bridge sleeve, and further causes the structure node to be damaged.

[0007] In some embodiments, the part of the limiting spring away from the first C-shaped connecting piece is arranged in the second through groove.

[0008] In some embodiments, one end of the limiting spring is fixed on the first C-shaped connecting piece, and the other end of the limiting spring extends into the second through groove.

[0009] In some embodiments, the two ends of the limiting spring are respectively fixed on the two opposite outer walls of the first C-shaped connecting piece, and the limiting spring is arranged in the second through groove.

[0010] In some embodiments, the limiting spring comprises: an arc-shaped sliding groove and a sliding block; the second C-shaped connecting piece is provided with the arc-shaped sliding groove on the wall close to the first C-shaped connecting piece; the first C-shaped connecting piece is provided with the sliding block on the side close to the second C-shaped connecting piece; the sliding block is matched with the arc-shaped sliding groove, and the sliding block is slidingly arranged in the arc-shaped sliding groove.

[0032] Please refer to Figures 1 to 4 The present embodiment provides a rotation limiting assembly for flexible bridge connection, comprising a first C-shaped connecting piece 10, a second C-shaped connecting piece 30 and a limiting spring 50, the first C-shaped connecting piece 10 is internally provided with a first through slot 11, the first through slot 11 is used for accommodating a first connecting rod 20; the second C-shaped connecting piece 30 is internally provided with a second through slot 31, the second through slot 31 is used for accommodating a second connecting rod 40, and the second C-shaped connecting piece 30 is rotatably connected with the second connecting rod 40; the side of the second C-shaped connecting piece 30 away from the second through slot 31 is rotatably connected with the side of the first C-shaped connecting piece 10 away from the first through slot 11; the limiting spring 50 is arranged on the first C-shaped connecting piece 10, and the limiting spring 50 is used for blocking the second C-shaped connecting piece 30 to prevent the extension direction of the first through slot 11 after rotation from being parallel to the extension direction of the second through slot 31.

[0033] First of all, it needs to be explained that the first connecting rod 20 and the second connecting rod 40 are respectively connected to the photovoltaic cleaning robot support and the photovoltaic support. The photovoltaic panel support is used to fix the photovoltaic panel 200, and the photovoltaic cleaning robot support is used to carry the photovoltaic cleaning robot 100. This structure design can ensure that the robot parking space and the support rotation process produce an angle difference within the support operation cycle.

[0034] In this embodiment, the assembly design aims to improve the efficiency and safety of photovoltaic panel 200 cleaning. Specifically, the first C-shaped connecting piece 10 is built-in with a first through slot 11 for accommodating the first connecting rod 20, while the second C-shaped connecting piece 30 is built-in with a second through slot 31 for accommodating the second connecting rod 40 and being rotatably connected with the second connecting rod 40. By rotatably connecting the side of the second C-shaped connecting piece 30 away from the second through slot 31 with the side of the first C-shaped connecting piece 10 away from the first through slot 11, this design allows the two connecting pieces to rotate relative to each other within a certain range, thereby realizing the flexible adjustment function of the angle difference between the robot parking space and the support rotation process. At the same time, the existence of the limiting function also avoids the damage of the structural parts due to the dead point. In order to prevent the extension direction of the first through slot 11 and the extension direction of the second through slot 31 from being parallel to each other during the cleaning process, the limiting spring 50 is placed on the first C-shaped connecting piece 10 to play a blocking role, ensuring that the two through slots operate at different angles, thereby avoiding the weak side of the rotating structure from bearing the photovoltaic cleaning robot 100.

[0035] Please refer to Figure 2 In some embodiments, the part of the limiting spring 50 away from the first C-shaped connecting piece 10 is placed in the second through slot 31.

[0036] In this embodiment, the design of the limiting spring 50 further optimizes the structure of the rotating limiting assembly. Specifically, the part of the limiting spring 50 away from the first C-shaped connecting piece 10 is placed in the second through slot 31. This layout not only increases the stability of the limiting spring 50, but also can more effectively control the rotation angle of the second C-shaped connecting piece 30. By embedding a part of the limiting spring 50 into the second through slot 31, a more precise angle limit can be formed in physical space, ensuring that the connecting pieces maintain the optimal relative position during the cleaning process, thereby improving the accuracy and reliability of the entire system.

[0037] Through the precise cooperation of the limiting spring 50 and the second through slot 31, more accurate and reliable angle control is achieved, effectively preventing excessive rotation of the connecting pieces, improving the stability and safety of the photovoltaic panel cleaning system, and at the same time simplifying the structure of the assembly and reducing the manufacturing cost.

[0038] In some embodiments, one end of the limiting spring 50 is fixed to the first C-shaped connecting piece 10, and the other end of the limiting spring 50 extends into the second through slot 31.

[0039] In this embodiment, the limit spring 50 is a 7-shaped or concave-shaped limit plate, one end of which is fixed to the outer wall of the first C-shaped connecting piece 10 by welding, bolting or bonding, and the other end of which extends into the second through slot 31. When the first C-shaped connecting piece 10 and the second C-shaped connecting piece 30 rotate, the limit spring 50 extending into the second through slot 31 contacts the second C-shaped connecting piece 30, blocking the second C-shaped connecting piece 30 from continuing to rotate. By fixing the limit spring 50 with the first C-shaped connecting piece 10, the hook-shaped baffle of the limit spring 50 occupies the rotation space of the second C-shaped connecting piece 30, thereby forming a limit, ensuring that the second C-shaped connecting piece 30 will not rotate to the weak side up, and ensuring that the structure will not be damaged or the cleaning efficiency will not be reduced due to excessive rotation during the cleaning process. In addition, the shape design of the limit spring 50 allows it to disperse the pressure applied at the contact point, reducing wear and tear and thus prolonging the service life of the assembly. Overall, the design of the limit spring 50 makes the operation of the photovoltaic panel 200 during the cleaning process safer and more reliable, and provides the cleaning robot with the necessary degree of freedom of operation.

[0040] Specifically, this limit spring 50 design provides more effective angle limitation. By preventing excessive rotation of the second C-shaped connecting piece 30, the limit spring 50 effectively reduces the risk of equipment failure, ensuring the smooth progress of the cleaning process, which in turn helps to improve the efficiency of photovoltaic cleaning and provides a more solid guarantee for the maintenance of renewable energy equipment.

[0041] In some embodiments, the limit spring 50 is fixed at both ends to the opposite outer walls of the first C-shaped connecting piece 10, and the limit spring 50 is placed in the second through slot 31.

[0042] In this embodiment, the limit spring 50 is a rod, both ends of which are fixed to the opposite outer walls of the first C-shaped connecting piece 10 by welding, bolting or bonding, and the middle of the limit spring 50 is in the second through slot 31. This layout ensures the stability and accuracy of the limit spring 50 in space. When the first C-shaped connecting piece 10 and the second C-shaped connecting piece 30 rotate, the limit spring 50 extending into the second through slot 31 contacts the second C-shaped connecting piece 30, blocking the second C-shaped connecting piece 30 from continuing to rotate. This design provides a precise and reliable angle limitation mechanism while maintaining a certain degree of flexibility. The symmetrical fixing method of the rod-shaped limit spring 50 makes the stress more uniform, reducing local stress concentration and helping to improve the overall stability and service life of the assembly. For a photovoltaic panel cleaning system, this design not only ensures that the cleaning robot works within a predetermined angle range, but also effectively prevents equipment damage or improper cleaning that may occur due to excessive rotation of the angle.

[0043] Please refer to Figure 3In some embodiments, the limit spring 50 comprises: an arc-shaped sliding groove 32 and a sliding block 12; the arc-shaped sliding groove 32 is arranged on the wall of the second C-shaped connector 30 close to the first C-shaped connector 10; the sliding block 12 is arranged on the side of the first C-shaped connector 10 close to the second C-shaped connector 30; the sliding block 12 is adapted to the arc-shaped sliding groove 32, and the sliding block 12 is slidingly arranged in the arc-shaped sliding groove 32.

[0044] The embodiment provides a rotation limiting assembly based on the sliding block 12 and the arc-shaped sliding groove 32, which realizes angle control through precise mechanical cooperation. Specifically, the assembly is composed of two key components: the arc-shaped sliding groove 32 installed on the wall of the second C-shaped connector 30 close to the first C-shaped connector 10, and the sliding block 12 installed on the side of the first C-shaped connector 10 close to the second C-shaped connector 30. The design of these two components enables them to be precisely adapted, and the sliding block 12 can freely slide in the arc-shaped sliding groove 32.

[0045] In the embodiment, when the first C-shaped connector 10 and the second C-shaped connector 30 rotate, the sliding block 12 can be limited after sliding to the end of the arc-shaped sliding groove 32. The sliding block 12 moves along the arc-shaped sliding groove 32, and its movement trajectory is determined by the arc shape of the sliding groove; specifically, the end of the arc-shaped sliding groove 32 blocks the continuous sliding of the sliding block 12, thereby realizing angle limiting. By using the design of the sliding block 12 and the arc-shaped sliding groove 32, the rotation angle control is realized through the precise cooperation of geometric shapes rather than traditional mechanical contact, providing a more accurate, smooth and reliable angle limiting mechanism. The arc-shaped sliding groove 32 can be designed with different curvatures and lengths according to actual needs, thereby providing a flexible angle limiting range and realizing flexible control of the rotation angle. For the photovoltaic panel cleaning system, this design not only ensures that the cleaning robot works within the predetermined angle range, but also smoothly limits the rotation, which not only reduces the direct contact and wear of mechanical components, but also absorbs part of the impact energy during rotation, effectively reduces the risk of equipment failure, and prolongs the service life of the equipment.

[0046] The shape design of the arc-shaped sliding groove 32 provides more adjustability for angle limiting, making the entire device more flexible and enhancing its adaptability. For the photovoltaic panel cleaning system, this design not only improves cleaning efficiency, but also provides a technical solution for precise control of renewable energy equipment.

[0047] In some embodiments, the arc-shaped sliding groove 32 is an arc-shaped through hole, and the sliding block 12 is a protrusion.

[0048] In this embodiment, the arc-shaped sliding groove 32 is designed as an arc-shaped through hole, and the sliding block 12 is in the form of a protrusion, so that the sliding block 12 can freely slide in the arc-shaped through hole, while ensuring the close fit between the sliding block 12 and the sliding groove. The curvature of the arc-shaped through hole can be adjusted as needed to achieve different limiting angles. During sliding, the sliding block 12 can move along the edge of the arc-shaped through hole until it reaches the end of the through hole. Through this design, the interaction between the sliding block 12 and the arc-shaped sliding groove 32 can provide smooth movement and reliable limiting function, reduce wear while ensuring effective limiting at the appropriate rotation angle, thereby improving the durability of the equipment and enhancing the operation stability and accuracy of the entire device.

[0049] Further, the above-mentioned scheme can be expanded as follows:

[0050] The limiting function design of the utility model includes spring limiting spring 50. By using the compression force of the spring, the bottom of the bolt and the nut are covered, and at this time the spring forms a limit in the second C-shaped connecting piece 30, which ensures that the second C-shaped connecting piece 30 will not rotate to the weak side up.

[0051] By adopting the above technical scheme, the utility model has the beneficial effects compared with the prior art:

[0052] It can effectively prevent the rotating part from entering the dead point position, causing the rotating part to be damaged or even the sleeve bridge to be damaged. At the same time, the setting of the limiting spring prevents the accidental parallel of the connecting rod during cleaning, reducing the risk of equipment damage caused by improper operation.
