Description

Technical Field

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

[0002] With growing energy demand and increasing attention to environmental protection, the application of solar photovoltaic technology in the construction sector is becoming increasingly widespread. Energy-saving photovoltaic modules used in building construction primarily consist of photovoltaic panels, supporting structures, and connecting components. As core components, photovoltaic panels are typically installed on the roof or exterior facade of a building.

[0003] When photovoltaic panels are installed on building facades, maintaining a specific cleaning angle is crucial. This is because the proper cleaning angle maximizes direct sunlight exposure, reduces obstruction caused by dust and debris, and thus improves the panels' power generation efficiency. Furthermore, the proper angle helps rainwater wash off the panels, further keeping them clean.

[0004] However, photovoltaic panels face numerous challenges in practical use. Wind impact is a key issue. In windy conditions, especially strong ones, the force exerted on photovoltaic panels can loosen their mounting components or even lift them off, causing damage or even panel fallout. This not only impacts the normal operation of the photovoltaic power generation system but also poses a safety hazard to the building itself, surrounding personnel, and facilities.

[0005] At present, in response to this problem, existing technologies usually use wind sensors to sense the wind speed. When the wind speed reaches a certain threshold, the driving device actively drives the photovoltaic panel to tighten so that it fits the wall surface, so as to reduce the impact of wind 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 susceptible to erosion by rain, resulting in internal circuit short circuit or corrosion; heavy rainfall such as hail may directly cause physical damage to the sensor; sun exposure will accelerate the aging of the sensor casing and internal components, affecting its performance and service life. Once the sensor fails, it will not be able to sense the wind speed changes in a timely and accurate manner, and thus will not be able to trigger the protection mechanism of the photovoltaic panel in time, making the photovoltaic panel in a dangerous state in windy weather, increasing the risk of damage and falling off;

[0006] In addition, in response to this problem, the announcement number CN113556082B was retrieved. The patent name is a patent for a distributed photovoltaic power generation device and its adjustment method. In strong wind weather, the patent will close the limit mechanism to unlock the support rods on the photovoltaic panels, and the support rods will then fold the photovoltaic panels onto the base. Although the device can achieve the folding protection of the photovoltaic panels, the device is limited by wind direction and wind speed, is not timely and sensitive, and the triggering conditions of the device are relatively simple. Summary of the Invention

[0007] In order to make up for the shortcomings of the existing technology, the present invention proposes a support and connection structure for energy-saving photovoltaic modules in construction. The present invention uses wind force to push the photovoltaic panels to overcome the locking force on the locking blocks to achieve active retraction of the photovoltaic panels into the storage slots, thereby protecting the photovoltaic panels in strong wind weather.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

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

[0036] Example 1: A support and connection structure for energy-saving photovoltaic modules for building construction, comprising a support shell 1 and a photovoltaic panel 2 in a storage slot 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 slot 11; a first movable slot 12 is provided at the lower position of the bottom of the storage slot 11; the first movable slot 12 passes through and is rotatably connected to a screw 13 with opposite threads at both ends; the left end of the screw 13 is fixedly connected to a knob 3; the two ends of the screw 13 are threadedly connected to a movable seat 4; the movable seat 4 is slidably connected to the first movable slot 12; the two movable seats 4 are connected by a second spring 41; the second spring 41 is sleeved on the screw 13 On the outer wall; the back of the photovoltaic panel 2 is fixedly connected to the hinge block 21; the two sides of the hinge block 21 are hinged to the corresponding movable seats 4 through the hinge rods 22; the upper ends of the two movable seats 4 are in contact with a locking seat 5; the locking seat 5 is provided with a locking groove 51 on the contact side of the movable seat 4; the locking block 52 is slidably connected in the locking groove 51; the locking block 52 is connected to the bottom of the locking groove 51 through a first spring 53; the movable seat 4 is provided with a card slot 42 on the contact side of the locking seat 5; the locking block 52 is provided with guide surfaces 521 on the left and right sides of one end of the card slot 42; the locking block 52 can be stuck in 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 exterior wall of the building using expansion bolts and other connectors, the photovoltaic panel 2 is connected to other parts of the corresponding photovoltaic module, such as batteries, so that the photovoltaic panel 2 can work. When sunlight shines on the outside of the photovoltaic panel 2, the photovoltaic panel 2 will convert 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 hinged on the movable seat 4 will be driven to move closer to each other. The hinged rod 22 When the locking block 52 is pressed against the locking groove 51, the locking block 52 will be able to move back into the locking groove 51 and avoid the locking. When the locking groove 42 on the movable seat 4 is aligned with the locking groove 51, the locking block 52 in the locking groove 51 is inserted into the corresponding locking groove 42 along the locking groove 51 under the action of the first spring 53, thereby locking 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 locking groove when the locking block 52 is inserted into the locking groove. 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 winds, the photovoltaic panel 2 will be subjected to wind force 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 hinged 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 along the lock slot 51 to overcome the first spring 53 and retract to the lock slot. 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. The threads at both ends of the screw rod 13 are arranged in opposite directions, which will cause the screw rod 13 to rotate, and the knob 3 will rotate as the screw 13 rotates. 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. Finally, the two hinged rods 22 tend to be straight. 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, thereby achieving better protection for the photovoltaic panel 2;If the photovoltaic panel 2 needs to be unfolded again, the screw 13 needs to be controlled to rotate. The rotation of the screw 13 will drive the two movable seats 4 to move closer to each other again, so that the locking groove 42 on the movable seat 4 is aligned with the locking groove 51 again, and the locking block 52 in the locking groove 51 is again locked into the locking groove 42. If strong winds occur again, the photovoltaic panel 2 will overcome the locking force of the locking block 52 under the action of the wind and be stored in the storage groove 11. This process is repeated. The present invention uses the wind to push the photovoltaic panel 2 to overcome the locking force on the locking block 52 to achieve active retraction of the photovoltaic panel 2 into the storage groove 11, thereby protecting the photovoltaic panel 2 in strong winds. Compared with folding using a wind sensor, the service life and stability are longer. In addition, because the wind directly acts on the photovoltaic panel 2, the photovoltaic panel 2 can be folded more timely and with higher sensitivity.

[0038] Example 2: A storage groove 54 is provided inside the locking seat 5; the storage groove 54 is slidingly and sealedly connected to the orifice plate 55; the square hole 551 in the center of the orifice plate 55 is slidingly and sealedly connected to the square bar 56; the square bar 56 is connected to the end of the storage groove 54 away from the lock groove 51; the square bar 56 is connected to the ball 562 through the third spring 561; the storage groove 54 is connected to the lock groove 51 through the step hole 57; the ball 562 is pressed against the orifice of the step hole 57 under the elastic force of the third spring 561; the storage groove 54 is connected to the external gas at one end away from the lock groove 51; the lock groove 51 is slidingly and sealedly connected to the locking block 52, and the interior is filled with liquid medium.

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

[0040] When the front side of the photovoltaic panel 2 is pushed by the wind, the two movable seats 4 will move along the screw 13 and move away from each other. In the process of the two movable seats 4 moving away from each other, the card slot 42 will be driven to stagger with the corresponding lock slot 51. The guide surface 521 on the lock block 52 will be squeezed by the notch of the card slot 42 and will overcome the first spring 53 and retract into the lock slot 51. After the two movable seats 4 are unlocked, they will directly move away from the limit position under the elastic force of the second spring 41, and the photovoltaic panel 2 will be directly stored in the storage slot 11. When the back side of the photovoltaic panel 2 is pushed by the wind, the photovoltaic panel 2 will pull the two hinged rods 22. The two hinged rods 22 will pull their respective movable seats 4, so that the two movable seats 4 will move along the screw 13 and move closer to each other. During the movement of the two movable seats 4 closer to each other, the card slot 42 will be driven to stagger with the corresponding lock slot 51. The guide surface 521 on the lock block 52 will be squeezed by the slot of the card slot 42 to overcome the elastic force of the first spring 53 and the third spring 561 and move closer to the bottom of the lock slot 51. The lock block 52 squeezes the liquid medium in the lock slot 51, so that the liquid medium in the lock slot 51 needs to overcome the elastic force of the third spring 561 to push open the ball 562. The outer wall of the ball 562 is aligned with the step hole. After the gap is formed in the lock groove 51, the liquid medium in the lock groove 51 will flow into the storage groove 54 along the step hole 57. After the liquid medium flows into the space in the storage groove 54, it will push the orifice plate 55 away from the step hole 57 until the lock block 52 is completely retracted into the lock groove 51. The liquid pressure in the lock groove 51 and the storage groove 54 is balanced, and the third spring 561 pushes the ball 562 to return to the step hole 57 and re-press it, so that the step hole 57 is sealed. That is, the liquid medium in the storage groove 54 cannot flow back into the lock groove 51, so that the lock block 52 in the lock groove 51 cannot be extended again, so that the lock groove 51 is retracted. 1 cannot form a secondary lock on the movable seat 4. In this way, after the two movable seats 4 approach each other and stagger away from the corresponding locking seat 5, the locking seat 5 completely unlocks the movable seat 4. The movement of the two movable seats 4 approaching each other will compress the second spring 41. The second spring 41 buffers the two movable seats 4 from approaching each other, thereby buffering 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 over the locking seat 5. The photovoltaic panel 2 is flipped and folded into the storage groove 11 during the process of the two movable seats 4 moving away from each other.When 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 move closer to 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 slot 58. The pressing block 6 will drive the first inclined surface 61 to squeeze the ball 562. The ball 562 is compressed to compress the third spring 561. The ball 562 is compressed to break away from the contact with the step hole 57, so that the step 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 flows into the lock slot 51 through the step hole 57 under the action of negative pressure. After the hydraulic pressure in the locking slot 51 and the storage tank 54 is balanced, the pressing block 6 is released, and the third spring 561 pushes the ball 562 back against the stepped hole 57. The locking block 52 snaps into the corresponding locking slot 42, locking the movable seat 4. This embodiment provides a one-way flow stepped hole 57 and a storage tank 54 within the locking seat 5. This prevents the locking block 52 from pushing the liquid medium in the locking slot 51 and preventing it from returning to its original position. Consequently, if the wind force on both the inside and outside of the photovoltaic panel 2 exceeds a threshold, the photovoltaic panel 2 will be triggered to retract, thereby providing more sensitive retraction protection for the photovoltaic panel 2.

[0041] Example 3: The storage groove 54 is provided with an adjustment groove 59 extending outward from one end away from the step hole 57; the square bar 56 is movably connected to the adjustment groove 59 with a gap therebetween; the adjustment groove 59 is provided with a first threaded hole 591 extending forward; the first threaded hole 591 is internally threadedly connected to a first bolt 592.

[0042] In this embodiment, first insertion holes 563 are evenly provided on the square bar 56 ; the first bolts 592 can be inserted into the first insertion holes 563 .

[0043] When the first bolt 592 is screwed in the first threaded hole 591, the end of the first bolt 592 will move out of the first insertion hole 563 to unlock the side bar 56. After the side bar 56 is unlocked, it will move along the adjustment slot 59 in the length direction. In the process of the side bar 56 approaching the step hole 57, the third spring 561 will squeeze the third spring 561, which will increase the elastic force of the third spring 561, so that the third spring 561 drives the ball 562 to press against the step hole 57, thereby increasing the opening resistance of the step hole 57. In this way, the locking force of the lock block 52 on the movable seat 4 is increased, so that the movable seat 4 needs to be subjected to a greater force to unlock and fold the photovoltaic panel 2, thereby reducing the sensitivity of unlocking and folding the photovoltaic panel 2; in the process of the square bar 56 moving away from the step hole 57, the pressing force of the third spring 561 on the ball 562 will be reduced, thereby reducing the opening resistance of the step hole 57 When the first spring 561 is engaged, the first spring 562 is engaged with the first bolt 593 and the first bolt 593 is engaged with the first spring 563. When the first spring 561 is engaged, the first bolt 592 is engaged with the first bolt 593 and the first bolt 593 is engaged with the first bolt 593. When the first spring 561 is engaged, the first bolt 592 is engaged with the first bolt 593 and the first bolt 593 is engaged with the first bolt 593.

[0044] Example 4: The bottom of the receiving groove 11 is provided with a second movable groove 14 connected to the first movable groove 12; the second movable groove 14 passes through the left and right sides and is fixedly connected to the square bar 7; the locking seat 5 is slidably connected to the square bar 7 through the square groove 50; the square groove 50 is provided with a second threaded hole 501 passing through it toward the front; the second threaded hole 501 is internally threadedly connected to the second bolt 502.

[0045] In this embodiment, the square bar 7 is evenly provided with second insertion holes 71 along the length direction; the end of the second bolt 502 can be inserted into the second insertion hole 71.

[0046] After the photovoltaic panel 2 is stretched to a certain tilt angle by using the movable seat 4 and the hinged rod 22, the second bolt 502 is screwed in the opposite direction to rotate in the second threaded hole 501, and the second bolt 502 will move out of the second insertion hole 71, thereby unlocking the locking seat 5, so that 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, thereby meeting the locking requirements of the photovoltaic panel 2 at different tilt angles and expanding 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 presses against the outer wall of the square bar 7 to lock the locking seat 5, and then the second bolt 502 is continued to be tightened, and the end of the second bolt 502 is inserted into the second insertion hole 71, so that the locking seat 5 is further locked.

[0047] Example 5: The knob 3 is rotatably connected in the cylindrical rotation groove 15; the rotation groove 15 is set on the support shell 1; the outer wall of the knob 3 is evenly provided with centrifugal grooves 31; the centrifugal block 32 is slidably connected in the centrifugal groove 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 rotary groove 15; protrusions 17 are evenly provided in the annular groove 16; a radial hole 34 is provided on the centrifugal block 32 in the radial direction of the knob 3; and the diameter of the radial hole 34 decreases as it approaches the center of the knob 3.

[0049] After the photovoltaic panel 2 is subjected to wind force greater than the locking force threshold of the lock block 52, the movable seat 4 is unlocked and moves along the screw 13. The two movable seats 4 will drive the photovoltaic panel 2 to fold into the storage groove 11 during the process of moving away from each other. The screw 13 will rotate with the movement of the movable seat 4. The rotation of the screw 13 will drive the knob 3 to rotate. The centrifugal block 32 on the knob 3 will drive the centrifugal block 32 to generate centrifugal force during the rotation. The centrifugal block 32 slides along the centrifugal groove 31 and away from the center of the knob 3 under the action of the centrifugal force. The gas outside the knob 3 will flow into the centrifugal groove 31 along the diameter hole 34. Since the diameter of the diameter hole 34 decreases as it approaches the center of the knob 3, the external gas can easily flow into the centrifugal groove 31 along the diameter hole 34. The centrifugal block 32 is in the centrifugal groove 31, so that the centrifugal block 32 can 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 friction 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 is reduced and the tension spring 33 pulls over the protrusion 17. The centrifugal block 32 rotates with the knob 3 again, so that the rotation speed of the knob 3 and the screw 13 is reduced, so that the photovoltaic panel 2 will be folded in 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, thereby achieving further protection for the photovoltaic panel 2 and avoiding vibration damage to the photovoltaic panel 2 caused by a faster folding speed.
