Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module support structures, and specifically to a support connection structure for energy-saving photovoltaic modules in building construction. Background Art

[0002] With the growth of energy demand and the emphasis on environmental protection, the application of solar photovoltaic technology in the building field is becoming increasingly widespread. The energy-saving photovoltaic modules used in building construction mainly consist of photovoltaic panels and supporting structures, connecting components, etc. As the core component, the photovoltaic panel is usually installed on the top or the outer wall of the building.

[0003] When the photovoltaic panel is installed on the outer wall of the building, it is crucial to ensure a certain cleaning angle. This is because a proper cleaning angle can enable the photovoltaic panel to receive direct sunlight to the greatest extent, reduce the sunlight blockage caused by the accumulation of dust and debris, thereby improving the power generation efficiency of the photovoltaic panel. At the same time, a proper angle helps rainwater wash the panel surface, further keeping the panel surface clean.

[0004] However, in actual use, the photovoltaic panel faces many challenges. Among them, the wind force influence is a key issue. In windy weather, especially strong wind weather, the wind force acting on the photovoltaic panel may cause the loosening of its fixing components or even lift it up, resulting in damage and detachment of the photovoltaic panel. This will not only affect the normal operation of the photovoltaic power generation system but also pose potential safety hazards to the building itself and the surrounding personnel and facilities.

[0005] Currently, to address this problem, the prior art usually uses a wind sensor to sense the wind force magnitude. When the wind force reaches a certain threshold, the photovoltaic panel is actively driven by a driving device to tighten and fit against the wall to reduce the influence of the wind force on the photovoltaic panel and protect the photovoltaic panel from damage. However, in order to ensure the detection accuracy of the wind sensor, it needs to be exposed to the external environment for a long time. In this way, the sensor is extremely vulnerable to rain erosion, resulting in internal circuit short-circuit or corrosion; strong precipitation weather such as hail may directly cause physical damage to the sensor; solar exposure will accelerate the aging of the sensor's housing and internal components, affecting its performance and service life. Once the sensor malfunctions, it cannot timely and accurately sense the wind force change, and thus cannot timely trigger the protection mechanism of the photovoltaic panel, making the photovoltaic panel in a dangerous state in strong wind weather, increasing the risk of damage and detachment;

[0006] In addition, in response to this problem, a patent with the publication number CN113556082B and the patent name of a distributed photovoltaic power generation device and its adjustment method was retrieved. When encountering strong wind weather, this patent will close the limit mechanism to unlock the support rod on the photovoltaic panel, and the support rod will then fold the photovoltaic panel on the base. Although this device can achieve the folding protection of the photovoltaic panel, it is restricted by the wind direction and wind speed, not timely and sensitive enough, and the triggering condition of this device is relatively single. Summary of the Invention

[0007] In order to make up for the deficiencies of the prior art, the present invention proposes a support connection structure for an energy-saving photovoltaic module in building construction. The present invention enables the photovoltaic panel to actively retract into the storage groove by the wind force pushing the photovoltaic panel to overcome the locking force on the locking block, thereby realizing the protection of the photovoltaic panel in strong wind weather.

Detailed implementation mode

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0035] As Figures 1 to 11 shown, the present invention includes the following embodiments:

[0036] Embodiment 1: A support connection structure for an energy-saving photovoltaic module in building construction, including a support shell 1 and a photovoltaic panel 2 in a storage groove 11 on the front side of the support shell 1; the upper edge of the photovoltaic panel 2 is hinged to the upper position of the storage groove 11; a first movable groove 12 is provided at the lower position of the bottom of the storage groove 11; the first movable groove 12 runs through left and right and rotatably connects a screw rod 13 with opposite threads at both ends; the left end of the screw rod 13 is fixedly connected to a knob 3; both ends of the screw rod 13 are in threaded transmission connection with a movable seat 4; the movable seat 4 is slidably connected in the first movable groove 12; the two movable seats 4 are connected by a second spring 41; the second spring 41 is sleeved on the outer wall of the screw rod 13; the back of the photovoltaic panel 2 is fixedly connected with a hinge block 21; both sides of the hinge block 21 are hinged to the corresponding movable seats 4 through hinge rods 22; the upper ends of the two movable seats 4 are in contact with a locking seat 5; a lock groove 51 is provided on the surface of the locking seat 5 in contact with the movable seat 4; a lock block 52 is slidably connected in the lock groove 51; the lock block 52 is connected to the bottom of the lock groove 51 through a first spring 53; a card slot 42 is provided on the surface of the movable seat 4 in contact with the locking seat 5; guiding surfaces 521 are provided on the left and right sides of one end of the lock block 52 close to the card slot 42; the lock block 52 can be inserted into the card slot 42; the elastic force of the first spring 53 is greater than the elastic force of the second spring 41.

[0037] After the support shell 1 is installed on the outer wall of the building by using expansion bolts and other connectors, the photovoltaic panel 2 is connected to other parts of the corresponding photovoltaic module, such as a battery, so that the photovoltaic panel 2 can work. After the sunlight shines on the outside of the photovoltaic panel 2, the photovoltaic panel 2 will convert the solar energy into electrical energy and store it in the battery. In order to achieve a better light-to-electricity effect of the photovoltaic panel 2 on the wall, the photovoltaic panel 2 is generally controlled to have a certain inclination angle with the wall. Specifically, the knob 3 can be turned, or a motor (not shown in the figure) can be used to drive the screw 13 to rotate. During the rotation of the screw 13, the two movable seats 4 on the screw 13 will be driven to move closer to each other. During the process of the two movable seats 4 approaching each other, the ends of the hinged rod 22 on the movable seat 4 will be driven to move closer to each other. The hinged rod 22 The angle will gradually become smaller, and the lower edge of the photovoltaic panel 2 will gradually move away from the bottom of the storage groove 11 and move out of the storage groove 11. The second spring 41 will be squeezed when the two movable seats 4 approach each other. The movable seat 4 will contact the guide surface 521 on the locking block 52 during the sliding process along the first movable groove 12. The locking block 52 will overcome the first spring 53 and retract into the locking groove 51 for avoidance when it is squeezed. Subsequently, after the slot 42 on the movable seat 4 is aligned with the locking slot 51, the locking block 52 in the locking groove 51 is inserted into the corresponding slot 42 along the locking groove 51 under the action of the first spring 53, so as to lock the movable seat 4. Then, the knob 3 is released. Since the elastic force of the first spring 53 is greater than that of the second spring 41, the second spring 41 is inserted into the slot when the lock block 52 is inserted into the slot During the process of moving the photovoltaic panel 2, the movable seat 4 cannot be pushed to move along the first movable groove 12, so that the photovoltaic panel 2 can be tilted upward at a certain angle to better receive sunlight; in the case of strong wind weather, the photovoltaic panel 2 will be affected by the wind when the wind blows towards the photovoltaic panel 2. The wind force received on the front of the photovoltaic panel 2 will be transmitted to the movable seat 4 through the hinge rod 22, and the movable seat 4 will be subjected to a thrust from the wind. When the sum of the thrust and the elastic force of the second spring 41 is greater than the elastic force of the first spring 53, the movable seat 4 will slide along the first movable groove 12 and drive the card slot 42 to stagger with the corresponding lock slot 51, so that the lock block 52 will be squeezed by the card slot 42 on the movable seat 4 and retracted to the lock slot along the lock slot 51 to overcome the first spring 53. 51, after the movable seats 4 are pushed away from each other by the wind and unlocked, the second spring 41 will continue to push the two movable seats 4 away from each other, and the two movable seats 4 will slide along the same first movable groove 12. During the movement of the two movable seats 4 away from each other, they will move at the respective ends of the screw rod 13, and the threads at both ends of the screw rod 13 are arranged oppositely, so that the screw rod 13 will rotate, and the knob 3 will rotate with the rotation of the screw 13. During the movement of the two movable seats 4 away from each other, the angle between the two hinged rods 22 will become larger and larger, and finally the two hinged rods 22 will tend to be straight, and the photovoltaic panel 2 will retract into the storage groove 11 for protection as the hinged rod 22 moves, so that the photovoltaic panel 2 is closer to the wall, so as to achieve better protection for the photovoltaic panel 2;If it is necessary to control the unfolding of the photovoltaic panel 2 again, it is necessary to control the rotation of the screw rod 13. The rotation of the screw rod 13 will drive the two movable seats 4 to approach each other again, so that the card slots 42 on the movable seats 4 are aligned with the lock slots 51 again, and the lock blocks 52 in the lock slots 51 are inserted into the card slots 42 again. If there is a strong wind weather again, the photovoltaic panel 2 overcomes the locking force of the lock block 52 under the action of the wind and is stored in the storage groove 11 again, and so on; the present invention realizes the active retraction and storage of the photovoltaic panel 2 in the storage groove 11 by the wind pushing the photovoltaic panel 2 to overcome the locking force on the lock block 52, thereby realizing the protection of the photovoltaic panel 2 in strong wind weather. Compared with using a wind sensor for folding, the service life and stability are stronger, and because the wind directly acts on the photovoltaic panel 2, the photovoltaic panel 2 is folded more timely and has higher sensitivity.

[0038] Embodiment 2: A storage groove 54 is arranged inside the locking seat 5; a hole plate 55 is slidably and sealingly connected in the storage groove 54; a square hole 551 in the center of the hole plate 55 is slidably and sealingly connected with a square bar 56; the square bar 56 is connected to one end of the storage groove 54 away from the lock groove 51; the square bar 56 is connected to a spherical ball 562 through a third spring 561; the storage groove 54 communicates with the lock groove 51 through a stepped hole 57; the spherical ball 562 abuts against the orifice of the stepped hole 57 under the elastic force of the third spring 561; one end of the storage groove 54 away from the lock groove 51 is communicated with the outside air; the lock groove 51 is slidably and sealingly connected with the lock block 52, and the inside is filled with a liquid medium.

[0039] In this embodiment, the stepped hole 57 is provided with a pressing groove 58 penetrating outwards; a pressing block 6 is slidably and sealingly connected in the pressing groove 58; the pressing block 6 contacts the spherical ball 562 through a first inclined surface 61.

[0040] When the front side of the photovoltaic panel 2 is pushed by the wind force, the two movable seats 4 will move along the screw rod 13 and move away from each other. During the process of the two movable seats 4 moving away from each other, the clamping grooves 42 will be staggered from the corresponding locking grooves 51. The guiding surface 521 on the locking block 52 will be pushed by the notch of the clamping groove 42 and retract into the locking groove 51 against the first spring 53. After the two movable seats 4 are unlocked, they will directly move away from each other to the limit position under the elastic force of the second spring 41, and the photovoltaic panel 2 will be directly stored in the storage groove 11. When the back side of the photovoltaic panel 2 is pushed by the wind force, the photovoltaic panel 2 will pull the two hinge rods 22, and the two hinge rods 22 will pull their respective movable seats 4. In this way, the two movable seats 4 will move along the screw rod 13 and move closer to each other. During the process of the two movable seats 4 moving closer to each other, the clamping grooves 42 will be staggered from the corresponding locking grooves 51. The guiding surface 521 on the locking block 52 will be pushed by the notch of the clamping groove 42 and move close to the bottom of the locking groove 51 against the elastic forces of the first spring 53 and the third spring 561. The locking block 52 squeezes the liquid medium in the locking groove 51, so that the liquid medium in the locking groove 51 needs to overcome the elastic force of the third spring 561 to push open the ball 562. After a gap is formed between the outer wall of the ball 562 and the stepped hole 57, the liquid medium in the locking groove 51 will flow into the storage groove 54 along the stepped hole 57. After the space in the storage groove 54 flows into the liquid medium, it will push the orifice plate 55 away from the stepped hole 57. Until the locking block 52 is completely retracted into the locking groove 51, the liquid pressures in the locking groove 51 and the storage groove 54 are balanced, and the third spring 561 pushes the ball 562 back to its original position and abuts against the stepped hole 57 again, sealing the stepped hole 57, that is, the liquid medium in the storage groove 54 cannot flow back into the locking groove 51, so that the locking block 52 in the locking groove 51 cannot protrude again, and the locking block 52 retracted into the locking groove 51 cannot form a secondary lock on the movable seat 4. In this way, after the two movable seats 4 move closer to each other and are staggered from the corresponding locking seats 5, the locking seats 5 completely unlock the movable seats 4. The mutual approach of the two movable seats 4 will compress the second spring 41, and the second spring 41 buffers the mutual approach of the two movable seats 4 to achieve buffering of the outward turning of the photovoltaic panel 2. After the wind force on the back side (i.e., the inner side) of the photovoltaic panel 2 weakens, the second spring 41 will push the two movable seats 4 away from each other and cross the locking seats 5, and the photovoltaic panel 2 will be flipped and folded into the storage groove 11 during the process of the two movable seats 4 moving away from each other;In the case where it is necessary to control the photovoltaic panel 2 to unfold again, the screw 13 will be rotated to drive the two movable seats 4 to approach each other. After the movable seat 4 drives the card slot 42 to align with the lock slot 51, the pressing block 6 is pressed to slide along the pressing groove 58. The pressing block 6 will drive the first inclined surface 61 to squeeze the spherical ball 562. The spherical ball 562 will be compressed by the pressure and compress the third spring 561. The spherical ball 562 will be separated from the contact with the stepped hole 57 under pressure, so that the stepped hole 57 is opened. The first spring 53 will push the lock block 52 away from the bottom of the lock slot 51. The liquid medium in the storage tank 54 will flow into the lock slot 51 through the stepped hole 57 under negative pressure. After the hydraulic pressure in the lock slot 51 and the storage tank 54 is balanced, the pressing block 6 is released. The third spring 561 pushes the spherical ball 562 to rest against the stepped hole 57 again, and the lock block 52 will snap into the corresponding card slot 42 to lock the movable seat 4. In this embodiment, by providing a stepped hole 57 and a storage tank 54 with unidirectional flow in the locking seat 5, after the lock block 52 pushes the liquid medium in the lock slot 51, the lock block 52 cannot be reset. Furthermore, when the wind forces on both the inner and outer sides of the photovoltaic panel 2 are greater than the threshold, the folding of the photovoltaic panel 2 will be triggered, and the photovoltaic panel 2 can be folded and protected more sensitively.

[0041] Embodiment 3: One end of the storage tank 54 away from the stepped hole 57 is provided with an adjusting groove 59 penetrating outward; the square bar 56 is movably connected to the adjusting groove 59 with a gap; the adjusting groove 59 is provided with a first threaded hole 591 penetrating forward; a first bolt 592 is threadedly connected to the first threaded hole 591.

[0042] In this embodiment, first jacks 563 are uniformly arranged on the square bar 56; the first bolt 592 can be inserted into the first jacks 563.

[0043] Before putting the photovoltaic panel 2 into use, first reverse-rotate the first bolt 592 to move within the first threaded hole 591. The end of the first bolt 592 will move out of the first jack 563, realizing the unlocking of the square bar 56. After the square bar 56 is unlocked, it will move along the adjustment groove 59 in the length direction. During the process of the square bar 56 approaching the stepped hole 57, it will squeeze the third spring 561, increasing the elastic force of the third spring 561, causing the third spring 561 to drive the ball 562 to increase the pressure against the stepped hole 57, making the opening resistance of the stepped hole 57 larger. In this way, the locking force of the lock block 52 on the movable seat 4 is improved, so that the movable seat 4 needs to receive a greater force to unlock and fold the photovoltaic panel 2, reducing the sensitivity of unlocking and folding of the photovoltaic panel 2; during the process of the square bar 56 moving away from the stepped hole 57, the pressing force of the third spring 561 on the ball 562 will be reduced, so that the opening resistance of the stepped hole 57 becomes smaller, so that the locking force of the lock block 52 on the movable seat 4 is reduced, so that the movable seat 4 can unlock and fold the photovoltaic panel 2 with a smaller force, improving the sensitivity of folding of the photovoltaic panel 2; after the movement of the square bar 56 is completed, rotate the first bolt 592 forward to move along the first threaded hole 591, and the end of the first bolt 592 will insert into the first jack 563 to realize the locking of the length direction of the square bar 56. In this way, the pressing force of the ball 562 by the third spring 561 is locked. The setting of the first jack 563 is to improve the locking stability of the square bar 56. The end of the first bolt 592 against the outer wall of the square bar 56 can also realize the locking; in this embodiment, by adjusting the initial pressing length of the third spring 561, the pressing force of the third spring 561 driving the ball 562 against the stepped hole 57 is changed, and then the sensitivity of unlocking the movable seat 4 is adjusted, so that the photovoltaic panel 2 can be folded under the influence of different wind forces.

[0044] Embodiment 4: A second movable groove 14 communicating with the first movable groove 12 is provided at the bottom of the storage groove 11; the second movable groove 14 runs through left and right and is fixedly connected with a square bar 7; the locking seat 5 is slidably connected with the square bar 7 through a square groove 50; a second threaded hole 501 runs through the square groove 50 forward; a second bolt 502 is threadedly connected in the second threaded hole 501.

[0045] In this embodiment, second jacks 71 are uniformly arranged along the length direction of the square bar 7; the end of the second bolt 502 can be inserted into the second jacks 71.

[0046] After the photovoltaic panel 2 is propped open at a certain inclination angle by the movable seat 4 and the hinge rod 22, the second bolt 502 is reversely screwed and rotates in the second threaded hole 501. The second bolt 502 will move out of the second jack 71, realizing the unlocking of the locking seat 5. In this way, the locking seat 5 can slide along the length direction of the square bar 7, changing the position of the locking seat 5 on the square bar 7, so as to meet the locking of the photovoltaic panel 2 at different inclination angles and expand the support and protection range of the photovoltaic panel 2. After the locking seat 5 completes the position movement on the square bar 7, the second bolt 502 is tightened. After the second bolt 502 is tightened, it abuts against the outer wall of the square bar 7 to realize the locking of the locking seat 5. Then, the second bolt 502 is continuously tightened, and the end of the second bolt 502 is inserted into the second jack 71 to realize the further locking of the locking seat 5.

[0047] Embodiment 5: The knob 3 is rotatably connected in a cylindrical rotating groove 15; the rotating groove 15 is arranged on the support shell 1; the outer wall of the knob 3 is evenly provided with centrifugal grooves 31; a centrifugal block 32 is slidably connected in the centrifugal grooves 31; the centrifugal block 32 is connected to the bottom of the centrifugal groove 31 through a tension spring 33.

[0048] In this embodiment, an annular groove 16 is provided on the inner wall of the rotating groove 15; protrusions 17 are evenly provided in the annular groove 16; a radial hole 34 is radially penetrated through the centrifugal block 32 on the knob 3; the aperture of the radial hole 34 decreases as it approaches the center of the knob 3.

[0049] After the locking force threshold of the lock block 52 is exceeded under the action of wind force on the photovoltaic panel 2, the movable seat 4 is unlocked and moves along the screw rod 13. During the process of the two movable seats 4 moving away from each other, they will drive the photovoltaic panel 2 to fold into the storage groove 11. The screw rod 13 will rotate as the movable seat 4 moves. During the rotation of the screw rod 13, it will drive the knob 3 to rotate. During the rotation of the centrifugal block 32 on the knob 3, it will drive the centrifugal block 32 to generate centrifugal force. The centrifugal block 32 slides along the centrifugal groove 31 under the action of centrifugal force and moves away from the center of the knob 3. The gas outside the knob 3 will flow into the centrifugal groove 31 along the radial hole 34. Since the aperture of the radial hole 34 decreases as it approaches the center of the knob 3, the outside gas can easily flow into the centrifugal groove 31 along the radial hole 34, enabling the centrifugal block 32 to smoothly extend out of the centrifugal groove 31 and contact the protrusion 17 in the annular groove 16. The protrusion 17 and the centrifugal block 32 generate frictional resistance. When the centrifugal block 32 is blocked by the protrusion 17, it will stop rotating until the centrifugal force of the centrifugal block 32 decreases and it moves over the protrusion 17 under the pull of the tension spring 33. Then, the centrifugal block 32 rotates with the knob 3 again. In this way, the rotation speed of the knob 3 and the screw rod 13 is reduced, so that the photovoltaic panel 2 will fold into the storage groove 11 at a slower speed, ensuring that the photovoltaic panel 2 is slowly folded under the action of wind force and the elastic force of the second spring 41, realizing further protection of the photovoltaic panel 2 and avoiding vibration damage to the photovoltaic panel 2 caused by a faster folding speed.
