Advantageous effects
Compared with the prior art, the invention has the following beneficial effects:
1. according to the invention, the connecting rope is pulled by bending the elastic plate, so that the swing rod rotates to sweep away the accumulated snow on the connecting plate, and the accumulated snow on the connecting plate is automatically cleaned by the elastic plate under the action of the accumulated snow, so that the connecting plate can not bear excessive load under the conditions of low temperature and heavy snow, the possibility of damage of the connecting plate is reduced, the maintenance times of maintenance personnel are reduced, and the maintenance cost is saved.
2. When the elastic plate is bent to a certain degree and snow on the elastic plate falls off, the elastic plate restores to deform, the swing rod resets under the action of the torsion spring, the strength of the connecting plate is guaranteed, the snow on the connecting plate is swept down in time, the burden of the connecting plate is relieved, meanwhile, the swing rod rotates towards the direction of the groove, and a part of the snow swept down by the swing rod falls on the elastic plate, so that the snow on the elastic plate is more, the elastic plate is further bent, the swing rod is further pulled to rotate, and meanwhile, as the photovoltaic modules are generally spliced together in a large scale, the grooves formed in the connecting plate can save a plurality of materials and reduce the production cost.
3. According to the invention, through the arrangement of the tray, the elastic plate is easier to bend, the larger the bending degree of the elastic plate is, the larger the swept area of the swing rod is, the better the effect of cleaning the connecting plate is, and when the tray moves to the bottommost end, the rotating plate in the tray rotates, so that the accumulated snow in the tray is further promoted to be removed, and the tray is favorable for recovering the deformation.
4. In the invention, because snow on the connecting plate can be frozen into harder ice, the part is difficult to be cleaned by the swing rod when the swing rod sweeps, and the pressure of the sharp conical salient points on the ice surface is higher when harder ice is swept by the conical salient points, so that the ice can be crushed and swept down, the thickening of stubborn snow layers is reduced, and the possibility of jamming of the swing rod is reduced.
5. The pull rope slides repeatedly at the edge of the groove, the abrasion to the pull rope is large, the contact area of the pull rope and the connecting plate can be increased through the curved surface of the contact position of the transition groove and the pull rope, the condition that the local stress of the pull rope is overlarge is reduced, the service life of the rope is prolonged, the stability of the device is improved, meanwhile, the transition groove limits the random sliding of the pull rope, and the pulling of the pull rope 17 is stable.
6. According to the invention, the connecting plate is mainly used for connecting the two floating platforms, the connecting plate is mainly subjected to the tension towards two sides of the floating platforms, the strength of the connecting plate is reduced due to the arrangement of the grooves, the tension resisting capacity of the connecting plate is reduced, the situation of strength reduction caused by the arrangement of the grooves is compensated through the reinforcing ribs, when the connecting plate is subjected to the tension of the floating platforms, the situation of fracture is not easy to occur, and the stability of the device is enhanced.
7. According to the invention, the connecting plate needs to bear larger pulling force due to the impact of waves and the action of wind, and the connecting plate has enough strength while ensuring the quality to be as small as possible, so that the groove is smaller, the accumulated snow on the elastic plate is less, and the degree of deformation of the elastic plate is lower, therefore, the angle of the pull rope for pulling the swing rod to rotate is smaller, the effect of the swing rod for cleaning the accumulated snow on the surface of the connecting plate is poor, more accumulated snow can be borne through the tray, the deformation degree of the elastic plate is larger, the swing rod can rotate to a larger extent when being pulled, the area for cleaning the swing rod is increased, and the effect of cleaning the accumulated snow on the connecting plate is enhanced.
8. Because the groove is small, the surface of the elastic plate is also small, accumulated snow swept by the oscillating bar is accumulated on the oscillating bar to influence the subsequent cleaning of the oscillating bar, the accumulated snow swept by the oscillating bar timely falls into a river by forming the first through groove in the surface of the elastic plate, the accumulation of snow on the elastic plate is reduced, meanwhile, the elastic plate can generate larger deformation when the same amount of accumulated snow is on the tray, the cleaning area of the oscillating bar is further increased, and the snow cleaning effect is improved.
9. When the elastic plate is bent to a certain degree, snow on the elastic plate and the tray can slide off, at the moment, when the elastic plate passes through the elastic balls, the elastic plate can vibrate to promote the snow on the elastic plate and the tray to slide off, and meanwhile, when the elastic plate is bent, the distance between the first magnet and the second magnet is shortened, the attraction force is larger, and the elastic plate is further bent.
10. When snow in the tray falls to a certain extent, the magnets III which attract each other are separated under the extrusion of the snow, and a part of the snow falls from the through groove II.
11. According to the invention, the swing rod is arranged in a bending manner, so that when the swing rod pushes accumulated snow, the accumulated snow falls towards a position far away from the bottom of the groove as far as possible, the deformation effect of the elastic plate is better, when the tray moves below the groove, part of snow falls on the tray, and when the snow in the tray does not slide, the weight of the tray is increased, the bending degree of the elastic plate is further increased, and when the snow in the tray slides, the snow falling on the tray vibrates, so that the cleaning effect on stubborn accumulated snow at the bottom of the tray is improved.
12. When the rotary plate is opened under the pressure of accumulated snow, the rotary plate rotates to the position of the knocking ball and collides with the knocking ball, the rotary plate vibrates to further promote the sliding of the accumulated snow, and meanwhile, the bottom of the rotary plate is stuck with the accumulated snow which is firmer and can also fall off under the vibration of the rotary plate.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1. A floating support platform for photovoltaic on water comprises a floating platform 1, as shown in figures 1-2, wherein a plurality of circular holes 11 are formed in the side surface of the floating platform 1; the top surface of the floating platform 1 is fixedly connected with a photovoltaic module 12; a connecting plate 13 is rotatably connected between the two floating platforms 1, a plurality of grooves 14 are formed in the side surface of the connecting plate 13, and elastic plates 15 are fixedly connected to the bottom surfaces of the grooves 14; a connecting column 18 is fixedly connected to the position, close to the groove 14, of the connecting plate 13, a swing rod 16 is connected to the connecting column 18 through a torsion spring, and a pull rope 17 is fixedly connected between the swing rod 16 and the end portion of the elastic plate 15. Under the conventional structure, when snows are heavy in the lake surface in winter, because the connecting plate 13 is relatively thin and is horizontally arranged, the snows cannot automatically slide off like an inclined photovoltaic plate, the connecting plate 13 can collect heavy snow, and the connecting plate 13 is greatly burdened, so that the connecting plate 13 can be broken. This photovoltaic on water's floating support platform when using, when heavy snow, through the pressure of snow to elastic plate 15, elastic plate 15 produces the deformation, elastic plate 15 passes through stay cord 17, make pendulum rod 16 rotate, sweep the snow on connecting plate 13, when elastic plate 15 bends to a certain extent, when the snow on elastic plate 15 drops, elastic plate 15 resumes deformation, pendulum rod 16 resets under the effect of torsional spring, when having guaranteed connecting plate 13 intensity, sweep the snow on connecting plate 13 in time, the burden of connecting plate 13 has been lightened, pendulum rod 16 rotates to recess 14 direction pivoted simultaneously, the snow swept by pendulum rod 16, partly can fall on elastic plate 15, make the snow on elastic plate 15 more, make elastic plate 15 further crooked, pulling pendulum rod 16 further rotates, simultaneously because photovoltaic module 12 generally makes large-scale concatenation together, so set up the use that many materials can be saved to the recess 14 on connecting plate 13, reduce the cost of production.
As shown in fig. 3, a plurality of conical salient points 2 are fixedly connected to the bottom of the swing rod 16. Because snow on the connecting plate 13 may be frozen into harder ice, when the swing rod 16 sweeps, the swing rod 16 is difficult to clean the part, and through the conical salient points 2, when harder ice is swept, the pressure of the sharp conical salient points 2 acting on the ice surface is larger, so that the ice can be crushed and then swept down, the thickening of a stubborn snow layer is reduced, and the possibility that the swing rod 16 is blocked is reduced.
As shown in fig. 4, the edge of the groove 14 is provided with a transition groove 3, and the side surface of the transition groove 3 is a curved surface. Stay cord 17 slides at recess 14 edge repeatedly, and is bigger to the wearing and tearing of stay cord 17, through the curved surface of crossing aqueduct 3 and stay cord 17 contact position, can increase the area of contact of stay cord 17 and connecting plate 13, reduces the too big condition of stay cord 17 local atress, has prolonged the life of rope, has promoted the stability of device, crosses aqueduct 3 simultaneously and has restricted the random slip of stay cord 17, makes pulling of stay cord 17 more stable.
As shown in fig. 2, the connecting plate 13 is provided with a rib 31 at a position perpendicular to the groove 14. Because the connecting plate 13 mainly connects two floating platform 1, the connecting plate 13 mainly receives the pulling force of floating platform 1 to both sides, seting up of recess 14 has reduced the intensity of connecting plate 13, has reduced connecting plate 13 and has resisted tensile ability, compensates the circumstances that sets up the intensity that recess 14 produced and descend through strengthening rib 31, when connecting plate 13 received floating platform 1's pulling force, the difficult cracked circumstances that appears has strengthened the stability of device.
As shown in fig. 2, a tray 4 is fixed to an end of the elastic plate 15. Because the impact of wave and the effect of wind make connecting plate 13 need bear great pulling force, connecting plate 13 still has sufficient intensity when guaranteeing that the quality is as little as possible, consequently recess 14 is smaller, the snow on elastic plate 15 is less, the degree that enables elastic plate 15 to warp is lower, consequently stay cord 17 pulling pendulum rod 16 pivoted angle is less, the effect that pendulum rod 16 cleaned connecting plate 15 surface snow is not good, can bear more snow through tray 4, make elastic plate 15 degree of deformation bigger, when pulling pendulum rod 16, pendulum rod 16 can rotate bigger range, the area that pendulum rod 16 cleaned has been promoted, the clearance effect to snow on connecting plate 13 has been strengthened.
As shown in fig. 2, a first through groove 5 is formed on the surface of the elastic plate 15 at a position close to the bottom of the groove 14. Because recess 14 is smaller, the surface of elastic plate 15 is also smaller, the accumulated snow that pendulum rod 16 swept down is piled up and can influence the subsequent clearance of pendulum rod 16 on pendulum rod 16, through seting up logical groove 5 on elastic plate 15 surface, make the accumulated snow that pendulum rod 16 swept down in time drop the river, the gathering of snow on elastic plate 15 has been reduced, simultaneously can elastic plate 15 produce bigger deformation when having equivalent accumulated snow on tray 4, the area that pendulum rod 16 cleaned also further increases, the effect of cleaning of accumulated snow has been promoted.
As shown in fig. 3, a plurality of elastic small balls 6 are fixedly connected to the side surface of the groove 14; a first magnet 61 is fixedly connected to the side surface of the groove 14, and the first magnet 61 is close to the bottom of the connecting plate 13; and a second magnet 62 is fixedly connected to the bottom surface of the elastic plate 15 near the end part. A first magnet 61 is fixedly connected to the side surface of the groove; the first magnet 61 is close to the bottom of the connecting plate 13; a second magnet 62 is fixedly connected to the position, close to the end, of the bottom surface of the elastic plate 15; when the elastic plate 15 is bent to a certain degree, the snow on the elastic plate 15 and the tray 4 can slide off, at the moment, when the elastic plate 15 passes through the elastic small ball 6, the elastic plate 15 can vibrate to promote the snow on the elastic plate 15 and the tray 4 to slide off, and meanwhile, when the elastic plate 15 is bent, the distance between the first magnet 61 and the second magnet 62 is shortened, the attraction force is larger, and the elastic plate 15 is further bent.
The surface of the tray 4 is provided with a second through groove 7, the second through groove 7 is rotatably connected with a pair of rotating plates 71, the side surfaces, close to each other, of the pair of rotating plates 71 are fixedly connected with a third magnet 72, and the third magnet 72 are mutually attracted. When the accumulated snow in the tray 4 reaches the degree of slipping, the magnets three 72 which attract each other are separated under the extrusion of the accumulated snow, a part of the accumulated snow falls from the through groove two 7, and after the snow on the tray 4 is reduced to a certain degree, the rotating plate 71 resets under the attraction of the magnets three 72 and the action of the torsion spring, so that the accumulated snow on the tray 4 is less, and the elastic plate 15 is deformed and restored under the action of the elasticity of the elastic plate.
The swing rod 16 is bent towards the groove 14; through 16 crooked settings of pendulum rod, make pendulum rod 16 when promoting snow, snow falls towards the position of keeping away from recess 14 bottom as far as, make elastic plate 15's deformation effect better, when tray 4 moves recess 14 below, there is partial snow to pound and fall on tray 4, when snow does not slide in tray 4, increase the further elastic plate 15's of weight bending degree of tray 4, when snow landing in tray 4, pound the vibrations that the snow that falls on tray 4 produced, the clearance effect to the stubborn snow in tray 4 bottom has been promoted.
Example 2. An above-water photovoltaic floating scaffold platform, comparative example 1, wherein another embodiment of the invention is: a plurality of connecting rods 81 are fixedly connected to the bottom of the tray 4, and knocking balls 8 are fixedly connected to the end portions of the connecting rods 81. When the rotating plate 71 is opened under the pressure of the accumulated snow, the rotating plate 71 rotates to the position of the knocking ball 8 to collide with the knocking ball 8, the rotating plate 71 vibrates, so that the accumulated snow is further promoted to slide off, and meanwhile, the bottom of the rotating plate 71 is adhered with the accumulated snow which is relatively firm and can also fall off under the vibration of the rotating plate 71.
The application method and the working principle of the device of the embodiment are as follows: through the pressure of snow to elastic plate 15, elastic plate 15 produces and warp, elastic plate 15 passes through stay cord 17, make pendulum rod 16 rotate, sweep the snow on the connecting plate 13, crooked to a certain extent when elastic plate 15, when the snow on the elastic plate 15 drops, elastic plate 15 resumes deformation, pendulum rod 16 resets under the effect of torsional spring, when having guaranteed connecting plate 13 intensity, in time sweep the snow on the connecting plate 13, the burden of connecting plate 13 has been alleviateed, pendulum rod 16 rotates to recess 14 direction pivoted simultaneously, the snow that is swept by pendulum rod 16, partly can fall on elastic plate 15, make the snow on elastic plate 15 more, make elastic plate 15 further crooked, pulling pendulum rod 16 further rotates. Through toper bump 2, when drawing harder ice, sharp-pointed toper bump 2 is greater in the pressure that acts on ice surface, and then can smash ice, and then sweep it off. The contact area of the pull rope 17 and the connecting plate 13 can be increased through the curved surface of the contact position of the transition groove 3 and the pull rope 17, the situation that the local stress of the pull rope is too large is reduced, meanwhile, the transition groove 3 limits the random sliding of the pull rope 17, and the pull of the pull rope 17 is stable. The strength reduction caused by the opening of the grooves 14 is compensated for by the reinforcing ribs 31. More accumulated snow can be borne by the tray 4, so that the elastic plate 15 has larger deformation degree, and the swing rod 16 can rotate by a larger amplitude when the swing rod 16 is pulled. Through seting up logical groove 5 on elastic plate 15 surface, make the snow that 16 rockers swept fall in the river in time, reduced the gathering of snowing on elastic plate 15, can elastic plate 15 produce bigger deformation when having equivalent snow simultaneously on tray 4. When the elastic plate 15 is bent to a certain degree, the snow on the elastic plate 15 and the tray 4 can slide off, at the moment, when the elastic plate 15 passes through the elastic small ball 6, the elastic plate 15 can vibrate to promote the snow on the elastic plate 15 and the tray 4 to slide off, and meanwhile, when the elastic plate 15 is bent, the distance between the first magnet 61 and the second magnet 62 is shortened, the attraction force is larger, and the elastic plate 15 is further bent. When the accumulated snow in the tray 4 reaches the degree of slipping, the magnets which attract each other are separated under the extrusion of the accumulated snow, a part of the accumulated snow falls from the second through groove 7, and after the snow on the tray 4 is reduced to a certain degree, the rotating plate 71 resets under the attraction of the magnets and the action of the torsion spring, so that the accumulated snow on the tray 4 is less, and the elastic plate 15 deforms and recovers more under the elastic action of the elastic plate. Through the bending arrangement of the swing rod 16, when the swing rod 16 pushes accumulated snow, the accumulated snow falls towards the position far away from the bottom of the groove 14 as far as possible, and the deformation effect of the elastic plate 15 is better.
