Description

TECHNICAL FIELD

[0001] The application relates to the technical field of photovoltaic installation, and particularly relates to a photovoltaic tracking mechanism of a new energy photovoltaic power system. BACKGROUND

[0002] With the promotion of global energy transformation, the new energy photovoltaic power system is widely used due to its clean and renewable characteristics. The operation efficiency and service life of photovoltaic panels, as the core components of energy conversion, directly affect the power generation performance of the system.

[0003] The heat dissipation mode of the traditional photovoltaic system mainly depends on natural convection or forced air cooling. The natural convection heat dissipation is significantly affected by the environmental wind speed and temperature. In the high-temperature and windless environment, the heat generated by the integrated circuit board and the transformer of the photovoltaic panel is easy to accumulate, resulting in overheating and failure of the equipment. Forced air cooling needs to additionally configure a fan driving device, which not only increases the system energy consumption and cost, but also may cause failure due to the dust blockage of the fan in the outdoor environment, and the maintenance is difficult;

[0004] The photovoltaic panel is exposed to the outdoor environment for a long time, and is easy to accumulate impurities such as bird droppings, dry branches and leaves, and dust. Artificial cleaning needs high-altitude operation, has safety hazards and high cost, is difficult to realize normal maintenance, and the existing automatic cleaning device mainly adopts a motor-driven scraper or a water spraying mechanism, which has a complex structure and needs additional power supply, and is limited in application in remote areas without power grids, and the mechanical transmission parts are easy to be eroded by wind and sand and fail.

[0005] The existing fixed mode of the photovoltaic panel installation cannot be automatically adjusted according to the wind force. The panel is easy to produce high-frequency vibration in strong wind, which causes fatigue fracture of the mechanical connection part. When the strong wind passes, the low pressure generated by the airflow turbulence on the surface of the panel may cause the panel to be adsorbed upward and loose, and even cause electrical connection failure.

[0018] 3. The impact of strong winds on the plywood causes the wind shield to extend upward from the inside of the plywood, so that the wind adjusts its direction under the guidance of the tilted wind shield, avoiding strong winds from blowing directly on the photovoltaic panels, reducing the problem of high-frequency vibration and fatigue fracture of the panels under continuous gusts.

[0040] The tooth surface of the second tooth disc 42 is helical, the base plate 2 is provided with a photovoltaic panel, and the bottom of the scraper 410 is attached to the top of the photovoltaic panel.

[0041] The base plate 2 is externally provided with a windproof assembly 6, which includes a clamping plate 61 symmetrically slidably connected to the side wall of the base plate 2, the inner wall of the clamping plate 61 is fixedly connected with a rack 62, the outer wall of the clamping plate 61 is symmetrically provided with a through hole 63, the inside of the clamping plate 61 is symmetrically rotatably connected with a hollow tooth disc 64, the inner wall of the hollow tooth disc 64 is fixedly connected with a sliding block 65, the side wall of the base plate 2 is symmetrically fixedly connected with a lead screw 66, the thread groove of the outer wall of the lead screw 66 is adapted to the sliding block 65 of the inner wall of the hollow tooth disc 64, the inside of the clamping plate 61 is slidably connected with a toothed rack 67, the toothed rack 67 is engaged with the hollow tooth disc 64, the top of the toothed rack 67 is linearly arrayed and fixedly connected with a second spring 68, one end of the second spring 68 away from the toothed rack 67 is fixedly connected with a wind shield 69, the inside of the clamping plate 61 is symmetrically provided with a second guide slot 610, and the two sides of the wind shield 69 are slidably connected to the inside of the second guide slot 610.

[0042] The base plate 2 is slidably connected with a fixed suction cup 5, the bottom of the base plate 2 is rotatably connected with a gear 611, the gear 611 is engaged with the rack 62, the inner wall of the gear 611 is provided with a threaded sliding groove 612, the bottom of the fixed suction cup 5 is fixedly connected with a guide rod 613, and the outer wall of the guide rod 613 is provided with a protrusion matched with the threaded sliding groove 612.

[0043] The photovoltaic tracking support 1 is mounted on the bottom of the base plate 2, and the upper section of the second guide groove 610 is inclined towards the side close to the base plate 2.

[0044] In actual application, the staff hoists and puts the photovoltaic panel on the base plate 2, when the photovoltaic panel collides with the fixed suction cup 5 on the base plate 2, the photovoltaic panel is pressed downward to make the fixed suction cup 5 adsorb the photovoltaic panel, then the photovoltaic panel slides downward in the base plate 2, the fixed suction cup 5 slides downward to drive the guide rod 613 to slide in the gear 611, the protrusions on the surface of the guide rod 613 make the gear 611 rotate on the bottom of the base plate 2 by sliding in the threaded sliding groove 612 during the downward sliding of the guide rod 613 in the gear 611, the rotation of the gear 611 drives the two side meshing racks 62 to relatively close, so that the clamping plate 61 clamps and fixes the two sides of the photovoltaic panel.

[0045] When the photovoltaic panel is installed and put into use, the integrated circuit board and the transformer of the photovoltaic panel are accommodated in the storage box 38, the components of the photovoltaic panel are protected by the storage box 38, during the conversion of solar energy, the components generate heat in the storage box 38, which increases the temperature in the storage box 38 and affects the normal use of the equipment;

[0046] At this time, the equipment is put in an outdoor open area, and the wind is large, when the wind enters into the inside of the base plate 2 through the ventilation hole 31 and passes through the inside of the base plate 2, the wind pushes the venturi tube 32 in the inside of the base plate 2 to move transversely, the venturi tube 32 pushes the first sliding rod 39 to slide in the inside of the base plate 2 when moving, and the first spring 310 is extruded and elastically shrinks, after the venturi tube 32 moves, the air inlet hole 35 and the air inlet cabin 36 are connected, the wind passes through the inside of the venturi tube 32 when flowing, at this time, because the middle section diameter of the venturi tube 32 is reduced, the flow rate of the wind in the middle section of the venturi tube 32 is accelerated, so that the middle section of the inner cavity of the venturi tube 32 generates low pressure, at this time, because the venturi tube 32 is connected with the inside of the storage box 38 through the air inlet hole 35, the air inlet cabin 36 and the first air guide groove 37, when the middle section of the venturi tube 32 generates low pressure, the venturi tube 32 extracts air from the inside of the storage box 38, the heat in the inside of the storage box 38 is extracted into the inside of the venturi tube 32 together with the air, and is discharged to the outside of the equipment by the venturi tube 32.

[0047] In the process of heat being extracted from the storage box 38, the inside of the storage box 38 will also be in a low pressure state. At this time, because the top of the storage box 38 is covered with a photovoltaic panel, the photovoltaic panel will be tightly adsorbed to the top of the storage box 38 under the low pressure state in the inside of the storage box 38. Thus, the storage box 38 can automatically adjust the adsorption strength of the photovoltaic panel for different wind forces. Therefore, the photovoltaic panel can be loosely tightened when the wind force is small, thereby avoiding the problem of deformation caused by the photovoltaic panel being tightly contracted for a long time.

[0048] When the wind passes through the inside of the venturi tube 32, the venturi tube 32 will rotate in the inside of the base plate 2 by pushing the fan blade 33. When the venturi tube 32 rotates in the inside of the base plate 2, the first toothed disc 41 will be driven to rotate at the bottom of the base plate 2 through the meshing of the first sliding groove 34 and the first toothed disc 41. When the first toothed disc 41 rotates, the second toothed disc 42 meshing with the first toothed disc 41 will also rotate. When the second toothed disc 42 rotates, the carriage 44 will reciprocate in the inside of the base plate 2 through the connecting rod 43. When the carriage 44 slides in the through slot 48 of the square rod 47, the square rod 47 will swing around the rotating seat 46 as the rotating seat 46 and the second sliding rod 45 rotate at the top of the base plate 2. The square rod 47 will drive the cross rod 49 to swing during the swinging process. The cross rod 49 will scrape the surface of the photovoltaic panel through the scraper 410 during the swinging process, thereby converting the wind force into the power source for the swinging of the cross rod 49.

[0049] The rotation of the venturi tube 32 when the external wind passes through the inside of the venturi tube 32 drives the carriage 44 to reciprocate in the inside of the base plate 2 through the connecting rod 43. Thus, the cross rod 49 drives the scraper 410 to reciprocate on the photovoltaic panel around the rotating seat 46. The scraper 410 can reciprocate on the surface of the photovoltaic panel without additional driving equipment, thereby avoiding the bird droppings and the fallen leaves and branches from being wrapped onto the photovoltaic panel during the gale and storm. Thus, the photovoltaic panel can maintain a high irradiation area during use. The timely cleaning of the impurities on the photovoltaic panel can effectively avoid the erosion of the photovoltaic panel by the stains and improve the service life of the photovoltaic panel.

[0050] When the external wind is large, the strong wind will impact the clamping plate 61, causing the clamping plate 61 to slide towards the side close to the base plate 2. The clamping plate 61 will cause the lead screw 66 to be inserted into the through hole 63 during the sliding process. At this time, because the hollow tooth disc 64 rotates inside the clamping plate 61, and the sliding block 65 on the inner wall of the hollow tooth disc 64 is matched with the thread groove on the surface of the lead screw 66, when the hollow tooth disc 64 contacts the lead screw 66, the sliding block 65 will slide on the thread groove of the lead screw 66, thereby causing the hollow tooth disc 64 to rotate inside the clamping plate 61. The hollow tooth disc 64 will drive the toothed rack 67 engaged therewith to slide upward inside the clamping plate 61. When the toothed rack 67 slides upward, it will drive the top of the wind deflector 69 to extend outside the clamping plate 61. When the wind deflector 69 extends inside the clamping plate 61, under the influence of wind force, the wind deflector 69 will be blown obliquely upward out of the inside of the clamping plate 61. When the wind deflector 69 slides to the top of the second guide groove 610 on both sides, the wind deflector 69 cannot continue to slide upward. At this time, the wind deflector 69 is in an inclined state and located above the clamping plate 61, thereby reducing the force of the strong wind directly acting on the photovoltaic panel.

[0051] Through the impact of strong wind on the clamping plate 61, the wind deflector 69 extends upward from the inside of the clamping plate 61, and the wind is adjusted in direction under the guiding action of the inclined wind deflector 69, thereby avoiding the strong wind directly blowing against the photovoltaic panel and reducing the problem of fatigue fracture of the panel due to high-frequency vibration under continuous gusts. By avoiding the strong wind blowing against the surface of the photovoltaic panel, the problem of the photovoltaic panel being upwardly adsorbed due to low pressure caused by fast wind speed can be reduced, the problem of loosening of the installation of the photovoltaic panel can be reduced, the electrical connection and mechanical installation position of the photovoltaic panel can be effectively prevented from being damaged by strong wind, and the response capability of the equipment in windy weather can be improved.
