Description

Technical Field

[0001] This invention relates to the field of photovoltaic tracking bracket technology, specifically to a steering motor support for a photovoltaic tracking bracket that utilizes wind-assisted guidance. Background Technology

[0002] Photovoltaic power generation, as an existing technology, mainly refers to a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy source of photovoltaic power generation system is solar energy, which is a clean, safe and renewable energy source. More importantly, the photovoltaic power generation process does not pollute the environment or damage the ecosystem.

[0003] With the continuous development of related technologies, in order to increase the contact time between photovoltaic panels made of semiconductor materials and sunlight and increase power generation, researchers in related fields have proposed photovoltaic tracking bracket technology. For example, a utility model patent with publication number CN211321279U discloses a drive-linkage photovoltaic tracking bracket, including a track beam, a drive motor, a photovoltaic module mounting bracket, a mounting bracket drive rod, and a drive rod transmission mechanism. The photovoltaic module mounting bracket is rotatably mounted on the track beam. One end of the mounting bracket drive rod is fixedly connected to the photovoltaic module mounting bracket, and the other end of the mounting bracket drive rod is hinged to a slider. The slider can slide along the channel of the track beam. The drive rod transmission mechanism includes a threaded screw, a first traction cable, a second traction cable, and a... The system includes a rotating adjusting wheel; one end of the threaded screw is connected to the drive motor via a second traction cable, and the other end of the threaded screw is connected to the drive motor via a first traction cable wound around the rotating adjusting wheel; the threaded screw is fixedly connected to the slider; the rotating adjusting wheel includes a roller, a roller mounting assembly, an adjusting rod, an adjusting knob, and a baffle; the adjusting rod passes through the baffle and can move relative to the baffle along the length of the adjusting rod; the roller mounting assembly and the adjusting knob are located on opposite sides of the baffle, the adjusting knob is sleeved on one end of the adjusting rod and threadedly connected to the adjusting rod, and the roller is mounted on the other end of the adjusting rod via the roller mounting assembly; the roller is used to wound around the first traction cable; the baffle is fixed to one end of the track beam to fix the position of the rotating adjusting wheel. After use, the drive-linked photovoltaic tracking bracket provided by this utility model uses a connecting threaded screw to connect the cable and rotate through the adjusting wheel to make reciprocating motion, replacing the counterweight at the end of the previous connecting threaded screw. This can more stably ensure the stable synchronous operation of each solar panel, with a fast response speed, less effort, and lower energy consumption of the drive motor. It also reduces the load on the drive motor during operation, avoids the motor being in a state of overheating for a long time, reduces the wear of the motor's transmission components, and extends the service life of the motor.

[0004] It is clear from the above-mentioned existing technologies that the core technology is to use a motor, cable components, and roller components to form a drive-linked photovoltaic tracking bracket, which then performs long-distance, multi-structure, labor-saving steering adjustment. However, in reality, in addition to the increased load on the drive motor due to the long-distance transmission structure, the wind speed and direction in nature also affect the steering adjustment of the photovoltaic panel. If not properly planned and utilized, it will still increase the load on the drive motor inside the photovoltaic tracking bracket. Furthermore, the steering adjustment of the photovoltaic panel is not performed in real time all day. Therefore, in addition to providing the steering adjustment function, the photovoltaic tracking bracket also needs to provide pressure protection for the photovoltaic panel. However, the main connecting components in the existing technology are cable-like components, which have low structural strength and are not conducive to improving the pressure resistance of the photovoltaic panel. Summary of the Invention

[0005] This invention provides a steering motor support for a photovoltaic tracking bracket that utilizes wind-assisted guidance, thus solving the problems mentioned in the background art.

[0006] This invention provides the following technical solution: a photovoltaic tracking bracket steering motor support utilizing wind power-assisted guidance, comprising a main support frame, a motor support connected to one side of the front end structure of the main support frame, and two adjustable fixed frames on both sides of the top of the main support frame. Photovoltaic modules are fitted inside the inner sides of the two fixed frames, and rotating shafts are fixedly connected to the front and rear ends of the two fixed frames. Four rotating shafts are arranged in pairs and movably fitted into the side walls on both sides of the top of the main support frame via their respective bearings. The ends of the four rotating shafts protrude to the outer side of the top of the main support frame. A first transmission mechanism is connected between two rotating shafts mounted on the top front structure of the main support frame. A second transmission mechanism is also connected to one end of the rotating shaft near the motor support. A composite shaft is fitted on one side of the second transmission mechanism, and a servo motor is connected to one end of the composite shaft. A limit plate, a synchronous belt, and a top pressure adjustment component are fitted in the middle of the composite shaft. An auxiliary shaft is fitted at the bottom of the synchronous belt, and the other end of the composite shaft is fitted inside the front structure of the main support frame through a bearing. An anemometer is installed on the top of the motor support.

[0007] Both of the fixed frames are equipped with positioning arc plates at their bottoms, and the bottom surfaces of the positioning arc plates are fitted with arc-shaped square suction cup electromagnets. The shell structure at the bottom of the arc-shaped square suction cup electromagnets is installed on the inner wall of the bottom structure of the main support frame. The surface of the positioning arc plates is connected with arc-shaped sleeves and locking and limiting components, and the output end of the locking and limiting components is aligned with the groove clearance structure inside the arc-shaped sleeves.

[0008] The first transmission mechanism includes a first transmission chain, and transition transmission gears are meshed and connected to both sides of the first transmission chain. The inner sides of the middle of the two transition transmission gears are respectively fixedly sleeved with one end of two rotating shafts installed on the top front end structure of the main support frame for linkage. The first transmission mechanism has a long-distance transmission effect, thereby meeting the operation requirements of synchronous transmission of multiple fixed frames and rotating shafts.

[0009] The second transmission mechanism includes a second transmission chain, and both sides of the second transmission chain are internally meshed with main transmission gears. The two main transmission gears are respectively fixedly sleeved to one end of the rotating shaft installed on one side of the top front end structure of the main support frame and fixedly sleeved to the surface of one end of the composite shaft. The second transmission mechanism serves as a transitional structure for power output, firstly to provide room for the installation of the servo motor, and secondly to provide working conditions for the optimization of the subsequent structure.

[0010] The central structure of the composite shaft is composed of a conical structure and a columnar structure. One end of the columnar structure is fixedly sleeved with the inner side of the middle of the limiting sleeve, while the conical structure is movably sleeved with the inner side of the top of the synchronous belt. In addition to undertaking the power output of the servo motor, the composite shaft also provides structural clearance conditions for the subsequent power output of the synchronous belt to be adjusted in two ways: effective output and ineffective output.

[0011] Specifically, the top pressure adjustment component is internally equipped with a small hydraulic push rod, and the output end of the small hydraulic push rod is fixedly connected to a top pressure sleeve plate. The inner side of the top of the top pressure sleeve plate is movably sleeved on the outer side of the middle part of the composite shaft. The small hydraulic push rod is located on the inner side of the bottom of the servo motor but does not contact it. The housing structure at the bottom of the small hydraulic push rod and the housing structure at the bottom of the servo motor are both mounted on the top of the motor support with screws. The top pressure adjustment component is a power mechanism for the synchronous belt to reciprocate in the middle of the composite shaft, realizing the automatic displacement of the synchronous belt and optimizing the use effect of the synchronous belt.

[0012] In particular, a constraint shaft is snapped into the inner side of the middle part of the top pressure sleeve plate, and one end of the constraint shaft is welded and fixed to the surface of the front end structure of the main support frame. The constraint shaft constrains and guides the reciprocating movement of the top pressure sleeve plate, thereby improving the stability of the movement of the top pressure sleeve plate.

[0013] The auxiliary shaft component includes a shaft structure inside, and one end of the shaft structure is equipped with a bearing seat through a bearing. The bottom of the bearing seat is fixed to the inner wall of the bottom of the motor support. The other end of the shaft structure is fitted inside the front end structure of the main support frame through a bearing. As a shaft support component, the auxiliary shaft component can rotate itself while providing installation support conditions for other components that are subsequently installed.

[0014] In particular, a wind baffle is fixedly connected to the surface of the middle part of the shaft structure, and the wind baffle is movably sleeved inside the motor support. The wind baffle will provide wind blocking and utilize the structural conditions to optimize the use effect of the auxiliary shaft.

[0015] The preferred embodiment has a limiting sleeve plate movably sleeved on the outer side of the bottom of the synchronous belt, and the bottom of the limiting sleeve plate is welded and fixed to the inner wall of the bottom of the motor support. The inner side of the top of the limiting sleeve plate is movably sleeved with the other end of the shaft structure, and the two structures do not contact each other. The surface of the other end of the shaft structure is in close contact with the inner wall of the bottom of the synchronous belt. The limiting sleeve plate constrains and limits the reciprocating movement of the synchronous belt, ensuring that the synchronous belt can perform reciprocating rotation operation at a specified horizontal position.

[0016] Specifically, the locking and limiting component is internally equipped with a second small hydraulic push rod, and the output end of the second small hydraulic push rod is fixedly connected to a T-shaped shaft. One end of the T-shaped shaft is aligned with the groove clearance structure inside the arc-shaped sleeve. The housing structure of the second small hydraulic push rod is fixedly installed on the surface of the positioning arc plate. The locking and limiting component is used in combination with the arc-shaped sleeve to mechanically lock and limit the positioning arc plate after rotation adjustment and the fixed frame associated with the positioning arc plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention forms a flip-type photovoltaic tracking bracket by assembling two fixed frames, rotating shafts correspondingly installed on the front and rear end surfaces of the two fixed frames, and a main support frame. The first transmission mechanism, the second transmission mechanism, the composite shaft, and the servo motor are assembled to form a transmission mechanism. After assembling and using the flip-type photovoltaic tracking bracket and the transmission mechanism, the photovoltaic modules installed in the two fixed frames are adjusted to track sunlight, thereby improving the power generation efficiency and power output of the photovoltaic modules. Moreover, the single transmission structure can adjust multiple sets of photovoltaic modules simultaneously, which can greatly reduce the operating cost of the device.

[0019] 2. This invention, through the assembly of a timing belt, auxiliary shaft, top pressure adjustment component, limit sleeve, anemometer, and motor support, forms a wind-powered load-reducing motor support. When integrated with the aforementioned flip-type photovoltaic tracking bracket and transmission mechanism, it enables real-time detection of the wind speed and direction in the environment where the photovoltaic modules are located, avoiding adjustments under conditions of strong winds in the opposite direction. This initially reduces the workload of the servo motor inside the transmission structure. When the wind direction is the same as the rotation adjustment direction, the wind deflector is blown by the airflow and drives the shaft structure inside the auxiliary shaft to rotate. At the same time, the top pressure adjustment component will drive and squeeze the timing belt, causing its top inner side to fit onto the columnar structure surface in the middle of the composite shaft. The rotating shaft structure will reciprocate rotational power towards the composite shaft through the timing belt, further reducing the workload of the servo motor inside the transmission structure.

[0020] 3. The present invention forms a magnetic anti-compression structure by means of the positioning arc plate and the arc-shaped square suction cup electromagnet, and forms a mechanical reciprocating locking mechanism by means of the arc-shaped sleeve plate and the locking and limiting component. After the magnetic anti-compression structure, the reciprocating locking mechanism and the above-mentioned flip-type photovoltaic tracking bracket and transmission mechanism are integrated and used, the fixed frame and photovoltaic module after rotation adjustment can be double fixed, which can fully improve the compressive strength of the fixed frame and the fixed frame-related structure.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 , Figure 2 , Figure 3 A photovoltaic tracking bracket steering motor support utilizing wind power-assisted guidance includes a main support frame 1. A motor support 11 is connected to one side of the front end structure of the main support frame 1. Fixed frames 2 are movably adjustable on both sides of the top of the main support frame 1. Photovoltaic modules 3 are fitted inside the inner sides of the two fixed frames 2. Rotating shafts 4 are fixedly connected to the front and rear ends of the two fixed frames 2. The four rotating shafts 4 are arranged in pairs and movably fitted into the side walls on both sides of the top of the main support frame 1 via their respective bearings. The ends of the four rotating shafts 4 protrude to the outer side of the top of the main support frame 1. A first transmission mechanism 5 is connected between the two rotating shafts 4 mounted on the top front end structure. The first transmission mechanism 5 includes a first transmission chain, and transition transmission gears are meshed on both sides of the first transmission chain. The inner sides of the middle of the two transition transmission gears are respectively fixedly sleeved with one end of the two rotating shafts 4 mounted on the top front end structure of the main support frame 1 for linkage. The first transmission mechanism 5 has a long-distance transmission effect, thereby meeting the operation requirements of synchronous transmission of multiple fixed frames 2 and rotating shafts 4, realizing the unified conditions of a single transmission structure for multiple moving parts, and reducing the cost of use.

[0031] In use, a transitional transmission gear inside the first transmission mechanism 5 is synchronously driven by the correspondingly connected rotating shaft 4, and then the remaining rotating shaft 4 is synchronously rotated under the meshing transmission of the first transmission chain and another transitional transmission gear, thereby enabling the two fixed frames 2 and the photovoltaic modules 3 installed on the inner sides of the two fixed frames 2 to be synchronously rotated and adjusted.

[0032] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 The rotating shaft 4 near the motor support 11 is connected to a second transmission mechanism 6. The second transmission mechanism 6 includes a second transmission chain, and main transmission gears are meshed on both sides of the second transmission chain. The two main transmission gears are fixedly sleeved to one end of the rotating shaft 4 installed on one side of the top front structure of the main support frame 1 and fixedly sleeved to the surface of one end of the composite shaft 7. The second transmission mechanism 6 serves as a transition structure for power output, providing space for the installation of power components and providing working conditions for subsequent structural optimization. The composite shaft 7 is fitted on one side of the second transmission mechanism 6, and a servo motor 8 is connected to one end of the composite shaft 7. A limit sleeve, a synchronous belt 10, and a top pressure adjustment component 9 are fitted in the middle of the composite shaft 7. The middle structure of the composite shaft 7 is composed of a conical structure and a columnar structure, and one end of the columnar structure is connected to the inner surface of the limit sleeve. The side is fixed and sleeved, while the conical structure is movably sleeved with the inner side of the top of the synchronous belt 10. In addition to bearing the power output of the servo motor 8, the composite shaft 7 also provides structural clearance for the subsequent power output of the synchronous belt 10 to be adjusted in two ways: effective output and ineffective output. After the two fixed frames 2, the rotating shafts 4 installed on the front and rear end structures of the two fixed frames 2, and the main support frame 1 are assembled, a flip-type photovoltaic tracking bracket is formed. The first transmission mechanism 5, the second transmission mechanism 6, the composite shaft 7, and the servo motor 8 are assembled together to form a transmission mechanism. After the flip-type photovoltaic tracking bracket and the transmission mechanism are assembled and used, the photovoltaic modules 3 installed inside the two fixed frames 2 are adjusted to follow the sunlight, thereby improving the power generation efficiency and power generation of the photovoltaic modules 3. Moreover, the single transmission structure can adjust multiple sets of photovoltaic modules 3 at the same time, which can greatly reduce the operating cost of the device.

[0033] In use, the servo motor 8 is started, which then drives the composite shaft 7, which in turn drives the second transmission mechanism 6 and the first transmission mechanism 5 in sequence. This causes the rotating shaft 4, the fixed frame 2, and the photovoltaic module 3 to rotate accordingly. The servo motor 8 is a product of Guangzhou Demark Motor Co., Ltd.

[0034] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6The top pressure adjustment component 9 has a small hydraulic push rod 91 inside, and the output end of the small hydraulic push rod 91 is fixedly connected to a top pressure sleeve 92. The inner side of the top of the top pressure sleeve 92 is movably sleeved on the outer side of the middle part of the composite shaft 7. The small hydraulic push rod 91 is located on the inner side of the bottom of the servo motor 8 but does not contact it. The housing structure at the bottom of the small hydraulic push rod 91 and the housing structure at the bottom of the servo motor 8 are both screwed onto the structure at the top of the motor support 11. The top pressure adjustment component 9 is the power mechanism for the reciprocating sleeve of the synchronous belt 10 in the middle of the composite shaft 7, realizing the automatic displacement of the synchronous belt 10 and optimizing the use effect of the synchronous belt 10. A constraint shaft 93 is snapped into the inner side of the middle part of the top pressure sleeve 92, and one end of the constraint shaft 93 is welded and fixed to the surface of the front end structure of the main support frame 1. The constraint shaft 93 constrains and guides the reciprocating movement of the top pressure sleeve 92, lifting the top pressure sleeve 92. To ensure the stability of the movement of the pressure plate 92, an auxiliary shaft 12 is fitted at the bottom of the synchronous belt 10. The auxiliary shaft 12 includes a shaft structure inside, and one end of the shaft structure is fitted with a bearing seat through a bearing. The bottom of the bearing seat is fixed to the inner wall of the bottom of the motor support 11. The other end of the shaft structure is fitted inside the front end structure of the main support frame 1 through a bearing. As a shaft support component, the auxiliary shaft 12 can rotate itself while providing installation support conditions for other components to be installed later. A wind deflector 13 is fixedly connected to the surface of the middle part of the shaft structure, and the wind deflector 13 is movably fitted inside the motor support 11. The wind deflector 13 will provide wind blocking and utilization structural conditions to optimize the use effect of the auxiliary shaft 12. The other end of the composite shaft 7 is fitted inside the front end structure of the main support frame 1 through a bearing. An anemometer 19 is installed on the top of the motor support 11.

[0035] When in use, the anemometer 19 detects the airflow speed and direction of the environment in which the whole device is located in real time, and detects the wind speed and direction of the environment in which the photovoltaic module 3 is located in real time, so as to avoid adjustment under strong wind conditions in the opposite direction and initially reduce the working load of the servo motor 8 inside the transmission structure.

[0036] When the wind direction is the same as the rotation adjustment direction, the wind deflector 13 is blown by the airflow and drives the shaft structure inside the auxiliary shaft 12 to rotate. At the same time, the top pressure adjustment component 9 will drive the synchronous belt 10 to squeeze, so that its top inner side is fitted onto the columnar structure surface in the middle of the composite shaft 7. Then the rotating shaft structure drives the synchronous belt 10 to reciprocate. The synchronous belt 10 reciprocates and applies rotational power to the composite shaft 7, further reducing the working load of the servo motor 8 inside the transmission structure.

[0037] Please see Figure 1 , Figure 5A limiting sleeve 14 is movably sleeved on the outer side of the bottom of the synchronous belt 10, and the bottom of the limiting sleeve 14 is welded and fixed to the inner wall of the bottom of the motor support 11. The inner side of the top of the limiting sleeve 14 is movably sleeved with the other end of the shaft structure, and the two structures are not in contact. The surface of the other end of the shaft structure is in contact with the inner wall of the bottom of the synchronous belt 10. The limiting sleeve 14 constrains and limits the reciprocating movement of the synchronous belt 10, ensuring that the synchronous belt 10 can perform reciprocating rotation operation at the specified horizontal position.

[0038] During use, as the synchronous belt 10 reciprocates, the inner space at the top of the limiting sleeve 14 comes into contact with the structure of the synchronous belt 10 moving back and forth to the inner side of the top of the limiting sleeve 14, ensuring that the synchronous belt 10 does not detach from the shaft structure inside the auxiliary shaft 12 without delaying the reciprocating rotation of the synchronous belt 10.

[0039] Please see Figure 1 , Figure 3 , Figure 7 Both fixed frames 2 have positioning arc plates 15 installed at their bottoms, and arc-shaped square suction cup electromagnets 16 are attached to the bottom surfaces of the positioning arc plates 15. The shell structure of the arc-shaped square suction cup electromagnets 16 is installed on the inner wall of the bottom structure of the main support frame 1. Arc-shaped sleeves 17 and locking and limiting components 18 are connected to the surface of the positioning arc plates 15, and the output end of the locking and limiting components 18 is aligned with the groove clearance structure inside the arc-shaped sleeves 17. The locking and limiting components 18 are provided with internal... The second small hydraulic push rod 181 is fixedly connected to a T-shaped shaft 182 at its output end. One end of the T-shaped shaft 182 is aligned with the groove clearance structure inside the arc-shaped sleeve 17. The housing structure of the second small hydraulic push rod 181 is fixedly installed on the surface of the positioning arc plate 15. The locking and limiting component 18 is used in combination with the arc-shaped sleeve 17 to mechanically lock and limit the positioning arc plate 15 after rotation adjustment and the fixed frame 2 associated with the positioning arc plate 15.

[0040] In use, the arc-shaped square suction cup electromagnet 16 is activated, and the magnetic attraction of the arc-shaped square suction cup electromagnet 16 is attached and fixed to the bottom surface of the positioning arc plate 15, which initially limits the fixed frame 2 and photovoltaic module 3 after rotation adjustment, thereby forming a magnetic anti-compression structure. Then, the second small hydraulic push rod 181 is activated, which pushes the T-shaped shaft 182 to move linearly, thereby making the T-shaped shaft 182 fit and engage with the arc-shaped sleeve plate 17, and then fix the fixed frame 2 and photovoltaic module 3 after rotation adjustment a second time, which fully improves the compressive strength of the fixed frame 2 and the associated structure of the fixed frame 2.
