Description

Technical Field

[0001] The present invention belongs to the field of solar thermal collectors, and particularly relates to a light-tracking solar thermal collector. Background Art

[0002] In a photovoltaic support device, angle adjustment is achieved by adjusting the height and inclination of the support. In actual operation, the angle adjustment usually needs to be carried out according to factors such as the local latitude and longitude, meteorological conditions, and the type of photovoltaic module. The angle adjustment of the photovoltaic support device usually uses two methods: manual or automatic. Manual angle adjustment requires manual climbing of the pole for adjustment, so it is suitable for small-scale power stations. Automatic angle adjustment, on the other hand, can achieve fully automatic operation and is widely used in large-scale power stations.

[0003] In order to improve the power generation efficiency of solar panels, an automatic tracking system can be adopted. The automatic tracking system can adjust the orientation of the solar panel in real time according to the position of the sun, ensuring that the solar panel is always facing the sun's rays. This system can greatly improve the power generation efficiency of the solar panel. Automatic angle adjustment usually uses devices such as angle adjustment piles, sensors, and control systems. First, the sensor obtains information such as the solar altitude angle and azimuth angle, then the control system calculates the height of the support to achieve automatic adjustment, and finally the actuator automatically rotates the support to a suitable position so that the solar heat collection panel faces the sun. Through angle adjustment, the photovoltaic module can achieve a higher power output on the same piece of land, thus saving land use costs.

[0004] Generally, the height of the front support of a solar photovoltaic power station is 1 - 2 meters, the height of the rear support is 2 - 4 meters, and the inclination angle of the support is 10 - 30 degrees. In order to prevent the solar heat collection panel from being blocked by buildings, usually the photovoltaic equipment is installed at a relatively high altitude and in an open area to prevent being blocked, so as to ensure that sufficient solar radiation can be received. For photovoltaic equipment installed in an open area or at a high altitude, since it needs to have an automatic light-tracking function, usually the solar heat collection panel and the bottom support are in a movable structure, so as to facilitate the rotation of the solar heat collection panel and cooperate with the sun's light direction for light-tracking work. Due to no obstruction, relatively speaking, the surrounding wind directly acts on the surface of the solar heat collection panel. And the rotatable solar heat collection panel needs to be connected to the motor shaft of the rotating device to achieve the rotation purpose, so in case of strong wind weather, due to the non-fixed installation, the solar heat collection panel is prone to shaking. In the case of long-term shaking, the structures such as the screws on the surface of the photovoltaic equipment will become loose, affecting the stability of the entire equipment.

[0005] In summary, the present invention provides a light-tracking solar thermal collector to solve the above problems. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a light-tracking solar heat collector to solve the problems such as the easy shaking of the solar heat collection plate due to non-fixed installation in the prior art.

[0007] A light-tracking solar heat collector includes a main frame body. A solar heat collection plate is installed on the main frame body through a frame base. A servo motor is installed at the bottom of the main frame body. The servo motor is connected to the bottom of the main frame body through a guiding component. The main frame body includes a guiding part, a cavity part, and a supporting foot part from top to bottom. The cavity part is a hollow structure, and the guiding component is arranged inside the cavity part. The servo motor is installed at the bottom of the cavity part and is arranged between multiple supporting foot parts. The guiding component includes a torque shaft, a lifting shaft, and a power shaft. The torque shaft is installed at the bottom of the frame base. The power shaft is fixedly connected to the servo motor through a coupling. The inside of the lifting shaft is a hollow structure. The power shaft and the torque shaft are respectively inserted into the lifting shaft movably from both ends of the lifting shaft. A locking sleeve is movably sleeved on the surface of the torque shaft. The locking sleeve is fixedly connected to the inner wall of the lifting shaft through a bearing sleeve. A tooth seat is fixedly connected to the surface of the lifting shaft. A seat ring is arranged above the tooth seat in a matching manner. The seat ring is installed at the bottom of the frame base. One end of the lifting shaft close to the power shaft is connected to the bottom of the main frame body through a hydraulic rod. The lifting shaft movably penetrates through the guiding part and extends into the cavity part.

[0008] Further, a spline groove is axially formed on the surface of the torque shaft. The inner wall of the locking sleeve is slidably connected to the spline groove through a spline bar. A locking plate is fixedly connected to the bottom of the locking sleeve. The locking plate is arranged at one end of the torque shaft away from the frame base.

[0009] Further, a plurality of locking grooves are formed on the locking plate. A matching plate is installed at one end of the power shaft inserted into the lifting shaft movably. Locking blocks corresponding to the locking grooves are installed on the matching plate.

[0010] Further, a ratchet tooth groove is formed at the bottom of the seat ring. A ratchet tooth ring is installed on the surface of the tooth seat. The ratchet tooth ring is arranged in a matching manner with the ratchet tooth groove. The middle part of the tooth seat is fixedly sleeved on the surface of the lifting shaft. A plurality of through holes are formed in the tooth seat. Spring rods are respectively arranged in the through holes. One end of each spring rod movably passes through the through hole and is fixedly connected to the top of the main frame body.

[0011] Further, a limiting ring is arranged at the top of the spring rod. The bottom of the spring rod is vertically connected to the surface of the guiding part.

A plurality of guide wheels are installed on the outer wall of the guide sleeve, and the guide wheels are respectively slidably arranged in the guide wheel groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the guiding assembly, the distance between the gear seat and the clamping seat ring can be adjusted by using the up-and-down movement function of the guiding assembly. On the one hand, the guiding assembly can connect and drive the power shaft and the torque shaft, and on the other hand, it can also lock the position of the frame base, so as to flexibly switch the adjustment in all directions. It can not only quickly complete the light chasing step with high sensitivity, but also quickly lock the solar heat collecting plate after adjustment to prevent it from being disturbed by strong winds.

[0016] 2. By setting the spring rod to support the gear seat, the gear seat is smoother when lifting, and the gear seat is limited by the spring rod and can only move up and down.

[0020] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] As Figures 1-7 shown, the present invention provides a light-tracking solar heat collector, including a main frame body 1. A solar heat collector panel 2 is installed on the main frame body 1 through a frame base 3. A servo motor 18 is installed at the bottom of the main frame body 1. The servo motor 18 is connected to the bottom of the main frame body 1 through a guide assembly. The main frame body 1 includes a guide part 101, a cavity part 102 and a support foot part 103 from top to bottom. The cavity part 102 is a hollow structure, and the guide assembly is arranged in the cavity part 102. The servo motor 18 is installed at the bottom of the cavity part 102 and is arranged between a plurality of support foot parts 103. The guide assembly includes a torque transfer shaft 5, a lifting shaft 6 and a power shaft 9. The torque transfer shaft 5 is installed at the bottom of the frame base 3. The power shaft 9 is fixedly connected to the servo motor 18 through a coupling. The inside of the lifting shaft 6 is a hollow structure. The power shaft 9 and the torque transfer shaft 5 are respectively inserted into the lifting shaft 6 movably from both ends of the lifting shaft 6. A locking sleeve 10 is movably sleeved on the surface of the torque transfer shaft 5. The locking sleeve 10 is fixedly connected to the inner wall of the lifting shaft 6 through a bearing sleeve 13. A spline tooth seat 16 is fixedly connected to the surface of the lifting shaft 6. A clamping seat ring 15 is arranged above the spline tooth seat 16. The clamping seat ring 15 is installed at the bottom of the frame base 3. One end of the lifting shaft 6 close to the power shaft 9 is connected to the bottom of the main frame body 1 through a hydraulic rod 7. The lifting shaft 6 movably penetrates through the guide part 101 and extends into the cavity part 102.

[0022] As an implementation manner of the present invention, a spline groove 14 is axially formed on the surface of the torque transfer shaft 5. The inner wall of the locking sleeve 10 is slidably connected to the spline groove 14 through a spline bar. A locking plate 11 is fixedly connected to the bottom of the locking sleeve 10. The locking plate 11 is arranged at one end of the torque transfer shaft 5 far from the frame base 3.

[0023] The position of the spline groove 14 and the spline bar is such that when the locking sleeve 10 rotates, it can drive the lifting shaft 6 to rotate synchronously. Moreover, the locking sleeve 10 can slide up and down on the surface of the lifting shaft 6. The locking sleeve 10 is rotatably connected to the lifting shaft 6 through a bearing sleeve 13, so that when the locking sleeve 10 rotates, it does not affect the position of the lifting shaft 6.

[0024] As an embodiment of the present invention, a plurality of locking grooves are provided on the locking plate 11. One end of the power shaft 9 that is movably inserted into the lifting shaft 6 is provided with a matching plate 12, and locking blocks corresponding to the locking grooves are installed on the matching plate 12.

[0025] Among them, by utilizing the lifting function of the lifting shaft 6, when the hydraulic rod 7 adjusts the height of the lifting shaft 6, the lifting shaft 6 moves downward, then the bearing sleeve 13 drives the locking sleeve 10 to slide on the rotating shaft 5, making the locking plate 11 approach the matching plate 12, and the locking block is inserted into the locking groove. Then when the servo motor 18 is started, the power shaft 9 can drive the lifting shaft 6 to rotate.

[0026] As an embodiment of the present invention, a ratchet tooth groove is provided at the bottom of the card seat ring 15. A ratchet tooth ring is installed on the surface of the card tooth seat 16. The ratchet tooth ring is arranged to match the ratchet tooth groove. The middle part of the card tooth seat 16 is fixedly sleeved on the surface of the lifting shaft 6. A plurality of through holes are provided in the card tooth seat 16, and spring rods 8 are respectively arranged in the through holes. One end of the spring rod 8 movably passes through the through hole and is fixedly connected to the top of the main frame body 1.

[0027] As an embodiment of the present invention, a limiting ring is provided at the top of the spring rod 8. The bottom of the spring rod 8 is vertically connected to the surface of the guiding part 101. A tension spring is movably sleeved on the surface of the spring rod 8, and the tension spring is arranged between the guiding part 101 and the card tooth seat 16.

[0028] Among them, the card tooth seat 16 matches the card seat ring 15, and the ratchet teeth on the ratchet tooth ring can be respectively caught in the ratchet tooth groove. After they match with each other, they can no longer shake. The card tooth seat 16 is supported by the spring rod 8, so that when the frame base 3 does not need to adjust the angle, the matching of the card tooth seat 16 and the card seat ring 15 makes it more stable, preventing the frame base 3 from shaking and ensuring the stability of the top solar heat collector panel 2 during use.

[0029] As an embodiment of the present invention, one end of the lifting shaft 6 is fixedly connected to the middle part of the card tooth seat 16, and the lifting shaft 6 penetrates through the card tooth seat 16.

[0030] Among them, the lifting shaft 6 can drive the tooth engaging seat 16 to lift. By adjusting the hydraulic rod 7, the height of the tooth engaging seat 16 is adjusted. Furthermore, the locking plate 11 in the lifting shaft 6 can also lift simultaneously. When the tooth engaging seat 16 descends, the locking plate 11 approaches the matching plate 12 until the bottoms match. Then, the tooth engaging seat 16 moves away from the clamping seat ring 15 and no longer limits the frame base 3. The servo motor 18 can drive the rotating force shaft 5 to rotate.

[0031] As an implementation manner of the present invention, the hydraulic rods 7 are respectively arranged on both sides of the lifting shaft 6. The hydraulic rods 7 are installed on the inner wall of the top of the cavity part 102. A push block is fixedly connected to the piston rod of the hydraulic rod 7, and the push blocks are respectively fixedly connected to both sides of the surface of the lifting shaft 6.

[0032] The hydraulic rod 7 is used to push the lifting shaft 6 to move up and down, and the lifting shaft 6 can freely move up and down in the cavity part 102.

[0033] As an implementation manner of the present invention, the guiding part 101 is of an annular structure, and a guide wheel groove is provided on the inner wall. A guide sleeve 4 is installed at the bottom of the frame base 3. The guide sleeve 4 is movably inserted into the guiding part 101. A plurality of guide wheels 17 are installed on the outer wall of the guide sleeve 4, and the guide wheels 17 are respectively slidably arranged in the guide wheel groove.

[0034] The guide sleeve 4 supports the entire frame base 3, enabling the frame base 3 to stably rotate on the surface of the main frame 1, and then adjusting according to the sunlight angle to adjust the position of the solar heat collector 2.

[0035] The solar heat collector 2 is driven by the servo motor 18 at the bottom. After the rotating force shaft 5 is engaged with the power shaft 9, the power shaft 9 can drive the rotating force shaft 5 to rotate, achieving the purpose of rotating the solar heat collector 2. When the rotating force shaft 5 and the power shaft 9 are engaged through the matching plate 12 and the locking plate 11, the lifting shaft 6 is lifted or lowered to adjust the height of the locking sleeve 10. The locking sleeve 10 slides on the surface of the rotating force shaft 5. When the locking sleeve 10 rotates, it drives the rotating force shaft 5 to rotate. The locking sleeve 10 can rotate self - sufficiently in the lifting shaft 6 through the bearing sleeve 13. When the lifting shaft 6 drives the tooth engaging seat 16 to move away from the clamping seat ring 15 while descending, the frame base 3 is no longer locked and can rotate freely.
