Description

Technical Field

[0001] This invention relates to photovoltaic panel truss installation technology, and more particularly to a quick-release locking mechanism based on a foldable photovoltaic panel support truss. Background Technology

[0002] As society becomes increasingly aware of environmental protection, traditional non-renewable energy sources are gradually being replaced by renewable energy sources such as solar and wind power. Solar energy, as a green and clean energy source, is being widely used in various aspects of people's lives. In order to achieve the collection and conversion of large amounts of energy, solar power generation systems typically involve the extensive installation of solar photovoltaic panels.

[0003] Existing solar photovoltaic (PV) panels typically require multiple panels to be spliced ​​and assembled together, supported and fixed by multiple trusses. Currently, the PV panel support trusses mainly use fasteners and bolts for positioning, thus installing the PV panels onto the erected trusses. When horizontal members are placed on vertical members, the presence of bolts or fasteners on the horizontal members results in uneven surfaces on the horizontal members, hindering PV panel installation. Furthermore, truss assembly is time-consuming. Therefore, this application provides a truss locking mechanism that enables rapid assembly. Summary of the Invention

[0009] In this invention, the second elastic tongue is provided with a second guide surface and a second blocking surface, and half of the second blocking surface enters the second through area.

[0010] In this invention, the transverse bar is provided with a first reinforcing protrusion and a second reinforcing protrusion arranged symmetrically, and the transverse bar is also provided with a limiting protrusion that cooperates with the second opening groove.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 17 As shown, this invention's quick-release locking mechanism based on a foldable photovoltaic panel support truss includes a concrete block 1, a photovoltaic panel 2, support columns 3, vertical rods 4, and horizontal rods 5. The concrete block 1 can be pre-buried in the soil, and then the columns 6 are inserted into the concrete block 1 to form a single integrated structure, improving stability. Symmetrically arranged columns 6 are provided on the concrete block 1, and first fixing members 7 and / or second fixing members 8 are provided on the columns 6. Support columns 3 are provided on the first fixing members 7. The first fixing members 7 and second fixing members 8 are provided at different positions on the concrete block 1. The support columns 3 are provided on the first fixing members 7, raising the upper end of the first fixing members 7, thereby tilting the photovoltaic panel 2 towards the end with stronger sunlight. The second fixing members 8 are directly connected to the vertical rods 4 to adjust the angle.

[0020] During installation, first connect the first fixing member 7 and the second fixing member 8 to the column 6, then connect the support column 3 to the first fixing member 7, and then place the mounting member 9 on the support column 3. Place the vertical rod 4 on the mounting member 9 and the second fixing member 8, keeping it in an inclined state. Next, install the locking assembly 10, which is located on the horizontal rod 5, in conjunction with the vertical rod 4, so that the horizontal rod 5 is fixed to the vertical rod 4, limiting its position. When installing the horizontal rod 5 onto the vertical rod 4, tools are not required; it can be directly locked and limited using the locking assembly 10.

[0021] A retainer 11 is provided on the horizontal bar 5. The retainer 11 can position the photovoltaic panel 2 and at the same time create an installation gap between the photovoltaic panels 2.

[0022] The retainer 11 consists of a base plate 12 and symmetrically arranged side plates 13. The side plates 13 are provided with positioning blocks 14. An installation area 15 is formed between the side plates 13 and the side plates 13. The base plate 12 is provided with positioning holes 16, and bolts are placed therein. Then the retainer 11 is fixed to the transverse rod 5. The photovoltaic panel 2 is restricted by the retainer 11, so that the photovoltaic panel 2 is installed on the transverse rod 5.

[0023] A vertical rod 4 is mounted on a support column 3. One end of the vertical rod 4 is connected to the support column 3 via a mounting piece 9, and the other end is connected to a second fixing piece 8. The interior of the vertical rod 4 is penetrated to form a first through area 17. The vertical rod 4 is provided with symmetrically arranged first opening slots 18, which are connected to the first through area 17.

[0024] The vertical rod 4 is provided with symmetrically arranged first stamping grooves 19, and a first elastic tongue 20 is provided in the first stamping groove 19, extending towards the first through area 17. The first elastic tongue 20 is provided with a first guide surface 21 and a first blocking surface 22, with half of the first blocking surface 22 entering into the first through area 17. The first stamping groove 19 is located at the upper end of the first opening groove 18, so that the first locking block 23 enters into the first through area 17 through the first opening groove 18, and then applies pressure to the first elastic tongue 20. Guided by the first guide surface 21, it passes over the first elastic tongue 20 and is then blocked by the first blocking surface 22.

[0025] The horizontal rod 5 and the vertical rod 4 are configured to work together. The photovoltaic panel 2 is installed on the horizontal rod 5. The interior of the horizontal rod 5 is penetrated to form a second penetration area 24. The horizontal rod 5 is provided with symmetrically arranged second opening slots 25, which are connected to the second penetration area 24.

[0026] The vertical rod 4 is provided with symmetrically arranged second stamping grooves 26, and a second elastic tongue 27 is provided in the second stamping grooves 26, extending toward the second through area 24. The second elastic tongue 27 is provided with a second guide surface 28 and a second blocking surface 29, half of the second blocking surface 29 entering the second through area 24.

[0027] The second stamping groove 26 is disposed on one side of the second opening groove 25, and this side direction is the direction in which the second locking member 30 moves. When the second locking block 31 moves from the second opening groove 25 into the second through region 24, the second locking member 30 can move along the interior of the second through region 24, so that the second locking block 31, guided by the second guide surface 28, passes over the second elastic tongue 27 and is then blocked by the second blocking surface 29.

[0028] The transverse rod 5 is provided with symmetrically arranged first reinforcing protrusions 32 and symmetrically arranged second reinforcing protrusions 33. The transverse rod 5 is also provided with limiting protrusions 34 that cooperate with the second opening groove 25. The position of the transverse rod 5 is limited by the cooperation of the limiting protrusions 34 and the second opening groove 25, allowing it to slide on the surface of the vertical rod 4. At the same time, the locking assembly 10 is used to limit the position of the transverse rod 5, thereby improving the stability and strength between the transverse rod 5 and the vertical rod 4.

[0029] The locking assembly 10 is used to connect the vertical rod 4 and the horizontal rod 5. The locking assembly 10 includes a first locking member 35 and a second locking member 30, which are hinged together by a hinge rod 36. The upper end of the first locking member 35 passes through the first opening slot 18 and is disposed in the first through area 17. The lower end of the second locking member 30 passes through the second opening slot 25 and is disposed in the second through area 24. During installation, the first locking member 35 and the second locking member 30 are arranged such that the second locking member 30 rotates from a vertical state around the hinge rod 36 to a horizontal state and is inserted into the second through area 24.

[0030] The first locking member 35 consists of a first locking block 23 and a connecting block 37. The bottom of the connecting block 37 forms an insertion hole 38, within which a spring 39 is installed. The connecting block 37 also has a hinge hole 40 perpendicular to the insertion hole 38. A hinge rod 36 is disposed within the hinge hole 40. The spring 39 has an arc-shaped segment 41 that mates with the hinge rod 36. The hinge hole 40 communicates with the insertion hole 38. The spring 39 provides a counterforce to the first locking member 35. When the first locking member 35 is positioned within the second through-area 24, the spring 39 is compressed, generating a counterforce that can push the first locking member 35, causing it to tend to move out of the second opening slot 25. However, due to the restriction of the second elastic tongue 27 and the second locking block 31, it cannot move out. The spring 39 ensures that the locking assembly 10 remains under tension after installation, allowing for a tighter fit between the horizontal rod 5 and the vertical rod 4.

[0031] The lower end of the connecting block 37 is provided with symmetrically arranged positioning blocks 14. The positioning blocks 14 are provided with blocking slopes 42 that cooperate with the second locking member 30. When the second locking member 30 does not enter the second through area 24, the blocking slopes 42 are used to support the second locking member 30.

[0032] The second locking member 30 consists of a second locking block 31 and symmetrically arranged hinge blocks 43. The hinge block 43 is provided with a rotating hole 44 that cooperates with the hinge rod 36. A clearance area 45 for accommodating the connecting block 37 is formed between the hinge blocks 43 and the hinge blocks 43.

[0033] The second locking block 31 is provided with a mounting block 46, and the mounting block 46 is provided with a first rotating rod 47 and a second rotating rod 48. Rollers 49 are provided at both ends of the first rotating rod 47 and the second rotating rod 48 respectively.

[0034] The second locking block 31 has a bottom surface 50, which contacts the inner wall of the second through region 24. A roller 49 near the bottom surface 50 is on the same horizontal plane as the bottom surface 50. The roller 49 guides the second locking member 30 to rotate. The area of ​​the second locking block 31 matches the area of ​​the second through region 24. The limiting protrusion 34 is placed within the second opening slot 25. The area of ​​the first locking block 23 matches the area of ​​the first opening slot 18. The width of the connecting block 37 matches the width of the first locking block 23. The width of the first through region 17 matches the length of the first locking block 23. The distance between the positioning blocks 14 matches the width of the second through region 24 and the second opening slot 25.

[0035] Because the positioning block 14 and the second through area 24 are matched in width, the second elastic tongue 27 and the second locking block 31 are matched, and the matching limiting protrusion 34 and the second opening groove 25 are matched, the first locking member 35 is located in the first opening groove 18, so that the locking assembly 10 cannot move in the first through area 17 and the second through area 24. At the same time, the locking assembly 10 restricts the position of the horizontal rod 5 and the vertical rod 4.

[0036] like Figure 17 As shown, when the locking assembly 10 is installed, the second locking member 30 is located at the lower end of the first locking member 35. Then, when the second locking member 30 is placed in the second through area 24, it rotates around the F direction. Guided by the tube wheel and the inclination of the second locking member 30 itself, the spring 39 is compressed by force, causing the second locking member 30 to move toward the second elastic tongue 27, passing over the second elastic tongue 27 to limit the position of the second locking member 30.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
