Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component transportation, in particular to a photovoltaic component transportation device with a prestressed double-cable structure in a sewage treatment plant. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (also known as photovoltaic modules), controllers and inverters. The main components are composed of electronic components. The solar panels are installed in an unobstructed place. With the development of renewable energy technology, photovoltaic power generation has become an important aspect of energy supply for sewage treatment plants.

[0003] In order to make better and more reasonable use of space, a supporting structure will be installed in the sewage treatment plant, and then steel ropes will be laid on top of the supporting structure. Then the photovoltaic modules will be installed on top of the steel ropes. The installation of photovoltaic modules does not take up space in the sewage treatment plant and can also realize the conversion of light energy into electrical energy. However, installing photovoltaic modules on top of steel ropes requires the use of transportation equipment.

[0004] Most of the existing transportation devices are carried out by crane or manually. However, the crane lifting method is not only labor-intensive but also expensive, while the manual lifting method has low work efficiency and requires manual transfer of each piece to the top of the steel cable for installation. Moreover, it is even more inconvenient for personnel to take the photovoltaic components when installing them above the sewage pool, and the installation efficiency is extremely low. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a prestressed two-cable structure photovoltaic module transportation device for a sewage treatment plant to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prestressed two-cable structure photovoltaic module transportation device for a sewage treatment plant, comprising a climbing frame body, a winding device is arranged at the bottom of the climbing frame body, and a slide is installed on the outer wall of the climbing frame body, a limiting frame is fixed on one side of the climbing frame body, and the limiting frame is engaged with the outer wall of the climbing frame body, and a plurality of groups of rollers are installed on the inner side of the limiting frame, the winding device comprises a winding roller fixed to the bottom of the climbing frame body, and a steel rope is wound around the outer wall of the winding roller, and a driving motor is arranged on one side of the winding roller, a fixed pulley is installed on the end of the climbing frame body, and a cross piece is fixed on one side of the slide Rod, and a groove is provided on one side of the cross bar, a carrying frame is movably installed on one side of the slide, and a convex rod is fixed on the outer wall of the carrying frame, and the outer wall of the convex rod is in contact with the inner wall of the groove, multiple groups of moving wheels are installed on the side of the carrying frame close to the slide, a screw rod is threadedly installed on the side of the carrying frame close to the slide, a turntable is movably installed on the end of the screw rod, three groups of fixing rods are movably installed on the outer wall of the carrying frame, a first connecting rod is movably installed on the end of one group of fixing rods, a second connecting rod is movably installed on the ends of two groups of fixing rods, and a first clamping block is fixed on the ends of the two groups of fixing rods, and a limiting rod is fixed on the side of the carrying frame close to the convex rod.

[0007] By adopting the above technical solution, the problem of inconvenient transportation of existing photovoltaic components is solved. When the photovoltaic components need to be transported, the photovoltaic components are placed on one side of the carrier frame, and then the reeling device can be operated to transport the photovoltaic components from the ground to a high place, thereby facilitating the installation of the photovoltaic components at a high place. The protruding rod cooperates with the groove on one side of the slide frame, so that the carrier frame will not fall to one side when the slide frame is transported upward, thereby ensuring that the photovoltaic components on one side of the carrier frame will not fall. The movable wheel can be limited by the set slide groove, and when the carrier frame is detached from the top of the slide frame, the movable wheel can slide to the top of the steel cable.

[0008] The utility model is further configured such that the number of the moving wheels is four, totaling two groups; a transmission rod is installed between the moving wheels in one group; a dual-axis motor is installed between the moving wheels in one group; the dual-axis motor is fixedly connected to the carrier frame, and both ends of the dual-axis motor are connected to the moving wheels; the two groups of moving wheels are connected by a transmission assembly, and the transmission assembly includes a pulley installed on one side of the two groups of moving wheels, and the two groups of pulleys are connected by a belt.

[0009] By adopting the above technical solution, the two sets of moving wheels are set up so that the dual-axis motor can drive the moving wheels to rotate during operation. When the moving wheels rotate, the other set of moving wheels is driven to rotate through the pulley, so that the carrier frame can be moved automatically. There is no need to push the carrier frame manually, which is more labor-saving. The dual-axis motor cooperates with the transmission assembly to realize the simultaneous movement of the four moving wheels, thereby avoiding slippage between the moving wheels and the steel cables.

[0010] The utility model is further configured such that the ends of the group of fixed rods and the limiting rods are fixed with cross rods, and multiple groups of second clamping blocks are fixed on the top of the cross rod, multiple groups of movable rods are fixed on one side of the cross rod, and the movable rods are slidably connected to the supporting frame, and a rubber pad is fixed on one side of the second clamping block.

[0011] By adopting the above technical solution, the photovoltaic components can be further limited by the set cross bar, avoiding the problem of the photovoltaic components falling. The contact area between the photovoltaic components and the multiple sets of second clamps can be increased. The rubber pad can not only prevent the second clamps from causing damage to the surface of the photovoltaic components, but also increase the friction between the second clamps and the photovoltaic components, so that the photovoltaic components will not fall easily.

[0012] The utility model is further configured such that a fixing column is fixed at one end of the first connecting rod and the second connecting rod, a movable groove is provided on the outer wall of the turntable, and the second connecting rod and the first connecting rod are located below the turntable, a rectangular block is fixed at the end of the screw rod, and a rectangular groove matching the rectangular block is provided inside the turntable.

[0013] By adopting the above technical solution, the second connecting rod and the first connecting rod can be movably connected to the turntable through the set movable groove. When the screw rotates, the screw will move, but the turntable will not move, avoiding the problem of damage between the turntable and the second connecting rod and the first connecting rod.

[0014] The utility model is further configured such that the other ends of the first connecting rod and the second connecting rod are both fixed with limiting columns, and the limiting columns are movably connected to the fixing rods, and the bottom of the supporting frame is provided with limiting grooves matching the limiting columns.

[0015] By adopting the above technical solution, when the fixed rod moves, it will drive the ends of the first connecting rod and the second connecting rod to move. The connection between the bearing and the limit column can avoid the problem of damage to the first connecting rod and the second connecting rod, and the opened limit groove can limit the movement direction of the limit column, so that the fixed rod can only slide horizontally inside the support frame.

[0016] The utility model is further configured that a slide groove is provided on one side of the slide frame.

[0017] By adopting the above technical solution, the movement direction of the moving wheel can be limited by the provided sliding groove, so that the moving wheel can slide to the top of the steel cable conveniently.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] 1. The utility model solves the problem of inconvenient transportation of existing photovoltaic components by providing a climbing frame body, a retracting device, a slide frame and a bearing frame. When the photovoltaic components need to be transported, the photovoltaic components are placed on one side of the bearing frame, and then the retracting device works to transport the photovoltaic components from the ground to a high place, thereby facilitating the installation of the photovoltaic components at a high place. The convex rod cooperates with the groove on one side of the slide frame, so that the bearing frame will not fall to one side when the slide frame is transported upward, thereby ensuring that the photovoltaic components on one side of the bearing frame will not fall. The movable wheel can be limited by the provided slide groove, and when the bearing frame is detached from the top of the slide frame, the movable wheel can slide to the top of the steel cable;

[0020] 2. The utility model is provided with a screw rod, a fixing rod, a rotating disk, a first clamping block and a second clamping block, so as to facilitate fixing of the photovoltaic assembly placed on one side of the carrier, and avoid the problem that the photovoltaic panel will fall when the carrier moves. When the slide moves upward from the ground, the first clamping block and the second clamping block clamp the outer wall of the photovoltaic assembly so that the photovoltaic assembly will not fall, and when the carrier moves above the steel cable, the first clamping block and the second clamping block will not cause the photovoltaic assembly to fall.

[0021] 3. The utility model solves the problem of the inconvenient movement of the carrier frame by providing a moving wheel, a dual-axis motor and a transmission assembly. The dual-axis motor can make the carrier frame slide on the steel cable without manual push, saving manpower, and the connecting frame and the limiting wheel can prevent the carrier frame from falling when sliding on the steel cable. The limiting wheels are located on both sides of the steel cable, thereby preventing the moving wheel from detaching from the steel cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 2

[0040] A prestressed two-cable structure photovoltaic module transportation device for a sewage treatment plant, such as Figure 7As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be described in detail here. The difference is that four groups of fixing rods 6 are fixed to the outer wall of the carrier frame 4, and the ends of two groups of fixing rods 6 are fixed with first clamping blocks 61, and the ends of the first clamping blocks 61 are installed with blocks 62 through damping shafts, and the ends of the two groups of fixing rods 6 are fixed with cross bars 7, and the tops of the cross bars 7 are fixed with multiple groups of second clamping blocks 71, and the bottom of the carrier frame 4 is installed with moving wheels 8, and the photovoltaic components are placed on one side of the carrier frame 4.

[0041] The working principle of the utility model is as follows: during transportation, the top of the climbing frame body 1 is set above the supporting structure, so that the climbing frame body 1 is not completely in contact with the supporting structure, and then the carrier frame 4 is connected to the slide 3, so that the protruding rod 43 on one side of the carrier frame 4 is inserted into the groove 32 on one side of the cross bar 31, and then the steel rope 22 wrapped around the outside of the winding roller 21 is pulled up, so that the outside of the fixed pulley 23 is connected to the slide 3, and then the photovoltaic component is placed on one side of the carrier frame 4, and multiple pieces can be placed, and then a set of fixed rods 6 are pushed, and when the fixed rods 6 move, the first connecting rod 53 is driven to move, and when the first connecting rod 53 moves, the end portion drives the turntable 52 to rotate , when the turntable 52 rotates, the screw rod 5 is driven to rotate, and when the turntable 52 rotates, the remaining two sets of fixing rods 6 are driven to rotate, so that the fixing rods 6 slide inside the supporting frame 4, so that the first clamping block 61 and the second clamping block 71 clamp the photovoltaic module to prevent the supporting frame 4 from falling when moving, and then the driving motor 24 is started, and the driving motor 24 drives the winding roller 21 to rotate, and the winding roller 21 rotates to reel in the steel rope 22, so as to pull the slide 3 to move upward, and when the slide 3 moves to the top of the climbing frame body 1, the driving motor 24 stops working, and at this time, the bottom of the slide 3 is in contact with the steel rope, and the slide groove 34 is in a parallel state with the steel rope;

[0042] Start the dual-axis motor 84, which drives the limiting wheel 83 to rotate. Then the moving wheel 8 slides out from the inside of the slide slot 34, and the moving wheel 8 slides to the top of the steel cable. Then the connecting frame 82 is installed on one side of the moving wheel 8 by bolts. The two sets of limiting wheels 83 fit with the steel cable, thereby limiting the movement direction of the supporting frame 4. The photovoltaic components are transported by the supporting frame 4, which replaces the problem of manual handling.
