Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically a wind-resistant and earthquake-resistant photovoltaic support for highway slopes. Background Technology

[0002] As an indispensable transportation infrastructure in modern society, highways and their slopes are often used to improve the utilization of land resources in these areas. Solar panels are typically installed on highway slopes to maximize solar energy utilization. However, since highway slopes are usually located in low-density suburban areas, the solar panels are frequently exposed to strong winds, which can damage them. Therefore, when installing solar panels on highway slopes, it is crucial to consider the wind and earthquake resistance of the solar panel supports to ensure the overall safety of the solar panels.

[0003] Chinese patent CN120074344A discloses a wind-resistant and shock-resistant self-balancing photovoltaic support, including an elastic support component connected to a pitch support. The elastic support component has a holding position and two sets of release positions. When wind force exceeding a predetermined level acts on the photovoltaic panel body, the abutment wheel can switch from the holding position to the release position. An energy storage structure is connected to the photovoltaic panel body and can drive the photovoltaic panel body to perform a deflection action. A locking shaft is connected to the energy storage structure and cooperates with a trigger frame. When the abutment wheel switches from the holding position to the release position, the energy storage structure is activated to drive multiple sets of photovoltaic panels to switch from a coplanar state to a non-coplanar state.

[0004] When the force of wind acting on the photovoltaic panel is greater than the elastic force of the first cylindrical spring, the energy storage structure releases the elastic potential energy of the second cylindrical spring, thereby adjusting the photovoltaic panel to make it more horizontal and thus reducing the impact of wind on the photovoltaic panel.

[0005] Although controlling the photovoltaic panel to move horizontally can improve its wind resistance, the horizontal movement of the photovoltaic panel is achieved by releasing the elastic potential energy of the spring. Therefore, this adjustment action is one-time and irreversible. After encountering strong winds, manual reset adjustment is required, which reduces the effectiveness. Furthermore, using the release of the elastic potential energy of the spring to drive the rotation of the photovoltaic panel can easily lead to excessive rotation speed, thereby causing damage to the photovoltaic panel.

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0023] Example

[0024] Please see Figure 1 - Figure 11 A wind-resistant and earthquake-resistant photovoltaic support for highway slopes includes an outer fixing frame 4, an inner mounting frame 7 is provided inside the outer fixing frame 4, and a first connecting component 5 and a second connecting component 6 are provided between the outer fixing frame 4 and the inner mounting frame 7. The first connecting component 5 and the second connecting component 6 are used to flexibly support the inner mounting frame 7. The inner mounting frame 7 has several photovoltaic panels 8 inside. The photovoltaic panels 8 have connecting shafts 81 at the center of both sides. The connecting shafts 81 are rotatably connected to the inside of the inner mounting frame 7. The outer end of the connecting shafts 81 is fixedly connected to an eccentric protrusion 82. The inner mounting frame 7 has an internal sliding connection to a limiting plate 9. The inner side of the limiting plate 9 has a drive groove 91, and the eccentric end of the eccentric protrusion 82 is slidably connected to the drive groove 91. An adjustment drive is provided on the outside of the limiting plate 9, and a wind measuring wheel 10 is rotatably connected to the outside of the outer fixed frame 4. The wind measuring wheel 10 is parallel to the top edge of the photovoltaic panel 8, and a wind speed detector 11 is provided on the shaft end of the wind measuring wheel 10. The wind speed detector 11 is electrically connected to the adjustment drive.

[0025] It should be noted that the wind measuring wheel 10 is parallel to the top edge of the photovoltaic panel 8. Therefore, the wind measuring wheel 10 is mainly affected by the front wind of the photovoltaic panel 8. The wind parallel to the photovoltaic panel 8 has a smaller effect on the wind measuring wheel 10, and can only drive the wind measuring wheel 10 to rotate slowly, or cannot drive the wind measuring wheel 10 to rotate at all. When the photovoltaic panel 8 is subjected to front wind, the front wind also acts on the wind measuring wheel 10 at the same time.

[0026] Therefore, the effect of wind blowing on the wind measuring wheel 10 is positively correlated with the effect of wind on the photovoltaic panel 8. By detecting the rotation speed of the wind measuring wheel 10, the effect of wind on the photovoltaic panel 8 can be detected. This can avoid the influence of strong winds from other directions and ensure the accuracy of the detection of wind force on the photovoltaic panel 8. Adjusting the state of the photovoltaic panel 8 according to the rotation speed of the wind measuring wheel 10 can improve the accuracy and effectiveness of the protection of the photovoltaic panel 8.

[0027] refer to Figure 1 and Figure 2 The wind measuring wheel 10 and the wind speed detector 11 are used together to detect the wind speed of the front wind of the photovoltaic panel 8. Specifically, when the front wind blows towards the photovoltaic panel 8, it simultaneously drives the wind measuring wheel 10 to rotate, and the rotation speed of the wind measuring wheel 10 is positively correlated with the wind speed. At the same time, the wind speed detector 11 is used to detect the rotation speed of the shaft of the wind measuring wheel 10, thus completing the detection of the wind speed of the front wind of the photovoltaic panel 8.

[0028] The wind speed detector 11 has a built-in control unit, which also sets the wind resistance threshold of the photovoltaic panel 8. When the forward wind speed of the photovoltaic panel 8 reaches the set threshold, the control unit is turned on and the drive is energized.

[0029] Adjust the drive control limit plate 9 to move. The limit plate 9 drives the photovoltaic panel 8 to flip through the drive groove 91 and the eccentric protrusion 82, so that the photovoltaic panel 8 tends to rotate horizontally and the rotation direction is downward flipping, so that the front of the photovoltaic panel 8 is facing down and the back is facing up.

[0030] This reduces the windward area of ​​the photovoltaic panel 8 and improves its wind resistance.

[0031] Furthermore, the photovoltaic panel 8 is flexibly connected to the inside of the outer fixed frame 4 through the inner mounting frame 7, the first connecting component 5, and the second connecting component 6. By flexibly installing the photovoltaic panel 8, the wind resistance performance of the photovoltaic panel 8 is improved, and the safety of the photovoltaic panel 8 in the face of wind force threshold is enhanced.

[0032] refer to Figure 1 and Figure 2In an optional embodiment, the system further includes a support column 1 for installation on a highway slope. A main support shaft 2 is rotatably connected to the top of the support column 1. A support frame 3 is fixedly connected to the outside of the main support shaft 2. An outer fixing frame 4 is fixedly connected to the outside of the support frame 3. An adjusting rod 12 is provided on the outside of the support frame 3. The adjusting rod 12 is installed on the outside of the support column 1 and is used to adjust the tilt angle of the support frame 3.

[0033] It should be noted that this device is configured with single-column support, and single-column support is only one support method in this embodiment.

[0034] Specifically, support column 1 is erected on the highway slope, including deep-buried column reinforcement and cement pouring reinforcement.

[0035] The outer fixing frame 4 is installed on the top of the support column 1 through the support frame 3 and the main support shaft 2. The outer fixing frame 4 can rotate around the main support shaft 2, which facilitates the adjustment of the main body tilt angle when the photovoltaic panel 8 is installed.

[0036] The adjusting rod 12 is equipped with an angle adjusting device for the outer fixed frame 4, including but not limited to a lead screw adjusting device. A motor is provided at the tail end, and a lead screw sleeve is provided at the output end of the motor. By starting the motor to rotate, the lead screw is moved, thereby achieving the effect of adjusting the tilt angle of the outer fixed frame 4.

[0037] refer to Figure 6 In an optional embodiment, the first connecting component 5 includes a load-bearing cable 51 fixedly connected to the outer fixed frame 4 at both ends, a plurality of support rods 52 are provided between the load-bearing cable 51 and the outer fixed frame 4, and a plurality of load-bearing rods 53 are provided between the load-bearing cable 51 and the inner mounting frame 7.

[0038] refer to Figure 7 The second connecting component 6 includes a positioning sleeve 61 and a positioning pull rope 62. The end of the positioning pull rope 62 is fixedly connected to a limiting ball 63. The four corners of the inner mounting frame 7 are provided with mounting holes 71. The positioning pull rope 62 passes through the mounting holes 71 through the limiting ball 63 to pull the inner mounting frame 7.

[0039] It should be noted that the load-bearing cable 51 and the positioning pull rope 62 support and pull the outer fixed frame 4, thereby achieving the effect of flexible support. By flexibly connecting the outer fixed frame 4 and the inner mounting frame 7, the vibration resistance of the photovoltaic panel 8 is effectively improved when the photovoltaic panel 8 vibrates due to wind. This avoids the photovoltaic panel 8 from vibrating under the action of wind due to rigid connection, and the possibility of damage due to vibration, thereby improving the working life of the photovoltaic panel 8.

[0040] refer to Figure 8The positioning sleeve 61 includes a sleeve rod 611 fixedly connected to the outside of the outer fixed frame 4. An adjusting block 612 is rotatably connected to the end of the sleeve rod 611. A threaded sleeve 613 is rotatably connected inside the sleeve rod 611. The threaded sleeve 613 is fixedly connected to the adjusting block 612. A movable block 614 is threadedly connected inside the threaded sleeve 613. A buffer spring 615 is fixedly connected to the outside of the movable block 614. A buffer block 616 is movably connected to the end of the buffer spring 615. The buffer block 616 is fixedly connected to the positioning pull rope 62. A guide rod 617 is fixedly connected inside the sleeve rod 611. Both the buffer block 616 and the movable block 614 are slidably connected to the outside of the guide rod 617.

[0041] It should be noted that the fixed end of the positioning pull rope 62 is equipped with a buffer block 616 and a buffer spring 615. When the photovoltaic panel 8 is subjected to wind force, since the photovoltaic panel 8 has an initial tilt angle, it is subjected to vertical and horizontal forces under the action of wind. In the direction perpendicular to the outer fixed frame 4, the inner mounting frame 7 is positioned and supported by several load-bearing rods 53. In the horizontal direction, it is positioned and supported by the four corner positioning pull ropes 62. Therefore, the swing amplitude of the photovoltaic panel 8 perpendicular to the outer fixed frame 4 is smaller than the swing amplitude of the photovoltaic panel 8 parallel to the outer fixed frame 4. By converting the vibration into the horizontal swing amplitude of the photovoltaic panel 8, the damage to the photovoltaic panel 8 is reduced, and the service life of the photovoltaic panel 8 is improved. At the same time, the buffer block 616 and the buffer spring 615 improve the buffering effect on the inner mounting frame 7 when horizontal to the outer fixed frame 4, effectively improving the vibration resistance of the photovoltaic panel 8 under the action of wind force and ensuring the service life of the photovoltaic panel 8.

[0042] Furthermore, by rotating the adjusting block 612, the adjusting block 612 drives the threaded sleeve 613 to rotate, and the threaded sleeve 613 drives the movable block 614 to move inside the positioning sleeve 61. The movable block 614 pushes the buffer block 616 through the buffer spring 615, and the buffer block 616 adjusts the pulling force of the positioning pull rope 62, thereby improving the buffer flexibility of the flexible installation of the inner mounting frame 7.

[0043] refer to Figure 3 , Figure 4 , Figure 5 and Figure 9 In one optional embodiment, the adjustment drive includes a slide rod 14, a positioning guide rod 13 is fixedly connected to the outside of the outer fixed frame 4, the slide rod 14 is slidably connected to the outside of the positioning guide rod 13, an inclined guide groove 141 is provided on the side of the slide rod 14, a driven rod 92 is fixedly connected to the outside of the limiting plate 9, the end of the driven rod 92 slides in the inside of the inclined guide groove 141 through a sliding pin, and a drive mechanism 15 for driving the slide rod 14 to move is provided on the outside of the limiting plate 9.

[0044] It should be noted that during the tilt angle adjustment of several single photovoltaic panels 8, the sliding rod 14 is moved by controlling the sliding rod 14. The sliding rod 14 drives the driven rod 92 to move along the vertical inner mounting frame 7 through the inclined guide groove 141. The driven rod 92 drives the limiting plate 9 to move. The limiting plate 9 drives the connecting shaft 81 to rotate through the driving groove 91 and the eccentric protrusion 82. The connecting shaft 81 drives the photovoltaic panel 8 to rotate, and the photovoltaic panel 8 flips face down.

[0045] Under the action of the sliding rod 14, several individual photovoltaic panels 8 tend to rotate horizontally, reducing the windward area of ​​the photovoltaic panels 8, thereby reducing the impact of wind on the photovoltaic panels 8, improving the photovoltaic panels 8's tolerance to strong winds, and enhancing the photovoltaic panels 8's wind resistance. At the same time, the photovoltaic panels 8, which tend to be horizontal, have their backs facing upwards, preventing sand and gravel from falling and damaging the working surface of the photovoltaic panels 8 under the action of strong winds. This not only ensures the photovoltaic panels 8's resistance to strong winds but also improves the photovoltaic panels 8's protection against sand and gravel in windy environments, effectively ensuring the working safety and service life of the photovoltaic panels 8.

[0046] refer to Figure 10 and Figure 11 In an optional embodiment, the drive mechanism 15 includes a housing 151 fixedly connected to the inner mounting frame 7. An electromagnetic actuator 152 is disposed outside the housing 151. The electromagnetic actuator 152 includes an electric push rod 153. An accumulator mechanism and a hydraulic mechanism are disposed outside the electric push rod 153. An inner partition 158 is fixedly connected inside the housing 151. The accumulator mechanism and the hydraulic mechanism are located on both sides of the inner partition 158, respectively. The hydraulic mechanism includes a drive plunger 1510 movably connected inside the housing 151. An adjusting rod 1511 is fixedly connected outside the drive plunger 1510. The adjusting rod 1511 and the slide rod 14 are fixedly connected.

[0047] The pressure accumulator mechanism includes a pressure rod 154 fixedly connected to the outside of the electric push rod 153, an inner control rod 155 sleeved on the outside of the electric push rod 153, a pressure accumulator plunger 156 slidably connected to the outside of the inner control rod 155, and a pressure accumulator spring 157 provided between the pressure accumulator plunger 156 and the pressure rod 154.

[0048] The inner partition 158 is equipped with a one-way valve 159, which controls the oil to flow unidirectionally from the oil chamber above the drive plunger 1510 to the oil chamber below the accumulator plunger 156. The inner partition 158 has a transition chamber 1581, which is connected to the oil chamber above the drive plunger 1510. The side of the transition chamber 1581 has an oil inlet hole 1582 for connecting to the oil chamber below the accumulator plunger 156. The transition chamber 1581 is movably connected to an inner valve ring 1551, which is fixedly connected to the bottom of the inner control rod 155. A valve ring spring 1552 is provided between the inner valve ring 1551 and the inner partition 158. The side of the inner valve ring 1551 has a through movable hole 1553.

[0049] Specifically, when the wind measuring wheel 10 rotates under the action of strong wind, the wind speed detector 11 detects the rotation speed of the wind measuring wheel 10. When the rotation speed of the wind measuring wheel 10 reaches the set threshold, the wind speed detector 11 controls the electromagnetic driver 152 to be energized. Then, the electromagnetic driver 152 drives the pressure rod 154 to move slowly through the electric push rod 153. The pressure rod 154 squeezes the accumulator spring 157, which increases the elastic potential energy of the accumulator spring 157 between the accumulator plunger 156 and the pressure rod 154.

[0050] When the pressure rod 154 presses against the inner control rod 155, the inner control rod 155 moves downward, and the inner control rod 155 drives the inner valve ring 1551 to move downward, so that the movable hole 1553 and the oil inlet hole 1582 coincide, thereby connecting the bottom oil chamber of the accumulator plunger 156 and the transition chamber 1581. Then, under the action of the accumulator spring 157, the hydraulic oil enters the top cavity of the drive plunger 1510 through the transition chamber 1581, thereby pushing the control rod 1511 to move outward. The control rod 1511 drives the slide rod 14 to slide. By controlling the movement of the slide rod 14, the tilt state of the photovoltaic panel 8 is adjusted.

[0051] By setting up a accumulator spring 157 and a accumulator plunger 156, when the wind speed detector 11 detects that the wind measuring wheel 10 has reached the speed threshold, the electromagnetic actuator 152 first controls the electric push rod 153 to push the pressure rod 154, which does not directly act on the drive plunger 1510 and has a certain accumulating time. At the same time, when the detected strong wind is caused by a car driving or other situations that bring gusts, when the wind speed decreases, the speed of the wind measuring wheel 10 decreases synchronously, and the wind speed detector 11 controls the electromagnetic actuator 152 to de-energize. If the pressure rod 154 does not control the inner valve ring 1551 to move downward at this time, the oil chamber below the accumulator plunger 156 remains sealed, and the control rod 1511 does not work. Furthermore, because the electromagnetic actuator 152 is de-energized, the electric push rod 153 loses its driving force, and the electric push rod 153 is pushed back to its original position by the reaction force of the accumulator spring 157.

[0052] The combined use of the accumulator spring 157 and the pressure rod 154 provides a buffer time range for the tilt adjustment of the photovoltaic panel 8, avoiding the influence of temporary gusts of wind. Only in the case of continuous strong winds will the photovoltaic panel 8 be controlled to rotate horizontally, reducing interference from unexpected factors and ensuring the working stability of the photovoltaic panel 8. At the same time, the accumulator plunger 156 and the drive plunger 1510 control the regulating rod 1511, using circulating hydraulic oil to control the drive, thereby ensuring the stability of the drive and preventing the photovoltaic panel 8 from rotating rapidly and being damaged. This ensures the stability and safety of the photovoltaic panel 8 during the tilt adjustment process.

[0053] In an optional embodiment, a return oil pipe 1512 is provided outside the lower oil chamber of the drive plunger 1510, and an external oil pump is provided outside the return oil pipe 1512.

[0054] When the photovoltaic panel 8 tends to be horizontal, and the wind speed detector 11 detects that the speed of the wind turbine 10 is lower than the set threshold, the electric actuator 153 loses the top pressure on the inner control rod 155. The inner valve ring 1551 is reset under the action of the valve ring spring 1552, causing the movable hole 1553 and the oil inlet hole 1582 to be misaligned. At the same time, the return oil pipe 1512 is controlled to work, pumping oil into the oil chamber below the drive plunger 1510, causing the control rod 1511 to reset. At the same time, the drive plunger 1510 pushes the upper oil through the one-way valve 159 back to the oil chamber below the accumulator plunger 156.

[0055] The combined use of the return oil pipe 1512 and the electromagnetic actuator 152 achieves the effect of intelligent control of the tilt angle of the photovoltaic panel 8. It can intelligently adjust the photovoltaic panel 8 to a wind-resistant state or a working state according to the external wind force, effectively ensuring the intelligence of the device.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
