Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, specifically relating to photovoltaic brackets. Background Technology

[0002] Existing courtyard photovoltaic (PV) systems often employ a truss design. Referring to Chinese utility model patent CN221509449U, a prefabricated truss courtyard PV system for residential use, relating to the field of PV power generation technology, is disclosed. This system supports PV panels and includes: several upper trusses and long columns; several parallel upper trusses, each including parallel upper and lower chords connected at both ends by short columns at an angle to the upper and lower chords; and several web members between the upper and lower chords; and several long columns fixedly connected to the short columns, extending along the length of the short columns. A crossbeam is vertically installed on the upper chord. This design often encounters errors during construction, such as varying pile top elevations due to different geological conditions, leading to gaps between the upper trusses and the crossbeams. To ensure the flatness of the components, direct welding is not possible. To ensure the quality and safety of the power station, some waste materials are used to fill these gaps during construction, but the strength of this filler steel cannot be guaranteed to meet structural requirements. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a photovoltaic power station and its beam installation leveling device. When a gap exists between the truss and the beam, the leveling device is installed to ensure the structural strength of the leveling position.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a leveling device for installing a photovoltaic power station crossbeam is provided, which is supported in the gap between the upper chord of the truss and the crossbeam. The leveling device includes a lower support member supported on the upper chord, a crossbeam support member that supports the crossbeam, and a leveling member connecting the lower support member and the crossbeam support member. The lower support member has a lower support groove that engages with the upper chord, and the crossbeam support member has a crossbeam support groove that engages with the crossbeam. The lower support member is welded to the upper chord in the leveling state, and the crossbeam support member is welded to the crossbeam in the leveling state.

[0006] Preferably, the bottom of the crossbeam support is provided with a screw hole, and the upper part of the leveling part is provided with a screw rod, which is threadedly connected to the screw hole.

[0007] Preferably, the leveling component has a rotating section on the lower side of the screw, and the rotating section has at least two force-applying planes on its radially outer side. The rotating section is used to connect with a wrench to drive the leveling component to rotate.

[0008] Preferably, the lower end of the leveling component is connected to a lower support seat supported on the upper chord, the upper side of the lower support seat is provided with a positioning section, the top of the lower receiving component is provided with a positioning hole, the positioning section passes through the positioning hole, and the lower support seat is limited to the lower end of the positioning hole.

[0009] Preferably, the screw hole protrudes downward from the bottom of the crossbeam support.

[0010] Preferably, the upper end of the screw hole is closed by the bottom wall of the crossbeam receiving groove.

[0011] Preferably, the upper end of the screw is connected to an upper support seat, and the upper support seat is in a limiting fit with the upper end of the screw hole.

[0012] Preferably, the length of the crossbeam support member is greater than the width of the crossbeam, and the length of the lower support member is greater than the width of the upper chord.

[0013] Preferably, the lower support and the crossbeam support are made of U-steel.

[0014] In addition, a photovoltaic power station is also provided, including the leveling device mentioned above.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. When there is a gap between the upper chord of the truss and the crossbeam, this leveling distance needs to be filled. The lower support of this leveling device can be inserted into the upper chord of the truss, and the crossbeam support can be moved up and down to fit into the crossbeam through the leveling device to achieve stable support. Then, the lower support is welded to the upper chord, and the crossbeam support is welded to the crossbeam.

[0017] Because the leveling component in the leveling device connects the lower support component and the crossbeam support component, the structure is stable. In addition, the lower support component is welded to the upper chord, and the crossbeam support component is welded to the crossbeam, which realizes a reliable connection between the leveling device and the upper chord and crossbeam of the truss. Therefore, the use of this leveling device can ensure the structural strength of the leveling position and ensure the overall stability of the photovoltaic support structure.

[0018] 2. To facilitate leveling operations, the leveling component has a rotating section on the lower side of the screw. The rotating section has at least two force-applying planes on its radially outer side for connecting with a wrench to drive the leveling component to rotate, thus facilitating operation.

[0019] 3. The lower end of the leveling component is connected to a lower support seat supported on the upper chord, which helps ensure the verticality of the leveling component. Additionally, the upper side of the lower support seat has a positioning section, and the top of the lower receiving component has a positioning hole. The positioning section passes through the positioning hole, and the lower support seat is in a limiting fit with the lower end of the positioning hole. The positioning hole is a round hole, and the positioning section is a cylinder, with a clearance fit between them. Therefore, the leveling component can rotate freely, but this clearance should not be too large, for example, 1mm-2mm is sufficient, to ensure the verticality of the leveling component.

[0020] 4. Because the screw hole protrudes downwards from the bottom of the crossbeam support, and the upper end of the screw hole is closed by the bottom wall of the crossbeam support groove, the upper end of the screw hole is not connected to the bottom wall of the crossbeam support. The bottom wall of the crossbeam support groove can be entirely supported on the bottom surface of the crossbeam, which helps to maintain the overall stability of the leveling device.

[0021] 5. The upper end of the screw is connected to an upper support seat, which is matched with the upper end of the screw hole for limiting. After leveling, the crossbeam is supported on the upper support seat, which helps to maintain the overall stability of the leveling device.

[0022] 6. The length of the crossbeam support member is greater than the width of the crossbeam, and the length of the lower support member is greater than the width of the upper chord. This ensures that the welding area between the lower support member and the upper chord, and the welding area between the crossbeam support member and the crossbeam, achieves a reliable connection between the leveling device and the upper chord and crossbeam of the truss.

[0023] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0037] This embodiment is for photovoltaic support systems using a truss design, where a leveling device is installed when there is a gap between the truss and the crossbeam.

[0038] like Figures 1 to 5 As shown, this embodiment provides a leveling device for installing crossbeams in a photovoltaic power station. The leveling device is supported in the gap between the upper chord 4 and the crossbeam 5 of the truss. The leveling device includes a lower support member 2 supported on the upper chord, a crossbeam support member 1 supporting the crossbeam, and a leveling member 3 connecting the lower support member 2 and the crossbeam support member 1. The lower support member 2 is provided with a lower support groove 21 that engages with the upper chord, and the crossbeam support member 1 is provided with a crossbeam support groove 11 that engages with the crossbeam. The lower support member 2 is welded to the upper chord 4 in the leveling state, and the crossbeam support member 1 is welded to the crossbeam 5 in the leveling state.

[0039] Using the above technical solution, when there is a gap between the upper chord of the truss and the crossbeam, this leveling distance needs to be filled. The lower support member 2 of this leveling device can be inserted into the upper chord of the truss 4, and the crossbeam support member 1 can be moved up and down to fit into the crossbeam 5 through the leveling member 3 to achieve stable support. Then, the lower support member 2 is welded to the upper chord 4, and the crossbeam support member 1 is welded to the crossbeam 5.

[0040] Because the leveling component in the leveling device connects the lower support component and the crossbeam support component, the structure is stable. In addition, the lower support component is welded to the upper chord, and the crossbeam support component is welded to the crossbeam, which realizes a reliable connection between the leveling device and the upper chord and crossbeam of the truss. Therefore, the use of this leveling device can ensure the structural strength of the leveling position and ensure the overall stability of the photovoltaic support structure.

[0041] Based on existing technology, the crossbeam and the upper chord are usually made of square steel tubing. Therefore, the crossbeam receiving groove 11 and the lower receiving groove 21 are designed as U-shaped grooves to match the shape of the crossbeam and the upper chord.

[0042] In some embodiments, the bottom of the crossbeam support 1 is provided with a screw hole 12, and the upper part of the leveling component is provided with a screw 31, which is threadedly connected to the screw hole 12. The leveling device can be placed in the space between the upper chord and the crossbeam after the screw 31 is threadedly connected to the screw hole 12 and the leveling component 3 is connected to the lower support 2. Alternatively, the leveling component can be connected to the lower support, the lower support placed on the upper chord, the crossbeam support 1 aligned with the crossbeam 5, and the screw 31 threadedly connected to the screw hole 12. After the leveling component rotates, due to the cooperation between the crossbeam support and the crossbeam, the crossbeam support cannot rotate but will rise until it completes the cooperation with the crossbeam support, thus achieving final leveling. Therefore, the height of the crossbeam support is adjustable, adapting to different leveling distances and various power station scenarios; furthermore, construction is convenient, reducing labor costs. Since the screw 31 and the screw hole 12 can be self-locking, they can maintain a level state, which makes it convenient for the lower support 2 to be welded to the upper chord 4 in the level state, and for the crossbeam support 1 to be welded to the crossbeam 5 in the level state.

[0043] To facilitate leveling operations, the leveling component 3 has a rotating section 32 on the lower side of the screw, located above the lower support component 2. The rotating section has at least two force-applying planes on its radially outer side. For example, two force-applying planes may be arranged opposite each other on both radial sides, or four or six force-applying planes may be evenly distributed circumferentially. The rotating section is used to connect to a wrench to rotate the leveling component for easier operation.

[0044] In some embodiments, the lower end of the leveling component 3 is connected to a lower support seat 34 supported on the upper chord. The bottom surface of the lower support seat 34 is a large flat surface, which helps to ensure the verticality of the leveling component. A positioning section 33 is provided on the upper side of the lower support seat, and a positioning hole 22 is provided on the top of the lower receiving component. The positioning section 33 passes through the positioning hole 22, and the lower support seat 34 is in a limiting fit with the lower end of the positioning hole. The positioning hole is a round hole, and the positioning section is a cylinder; the two are fitted with a clearance, so the leveling component can rotate freely. However, this clearance should not be too large, for example, 1mm-2mm is sufficient, to ensure the verticality of the leveling component.

[0045] In some embodiments, the bottom wall of the crossbeam receiving groove 11 is provided with a through-hole. To ensure the depth of the through-hole, the bottom wall of the crossbeam receiving groove 11 can be thickened, exceeding the thickness of the side walls.

[0046] like Figure 6 As shown, in some embodiments, the screw hole protrudes downward from the bottom of the crossbeam support 1, and the upper end of the screw hole is closed by the bottom wall of the crossbeam support groove. Thus, the upper end of the screw hole is not connected to the bottom wall of the crossbeam support. The bottom wall of the crossbeam support groove can be entirely supported on the bottom surface of the crossbeam, which helps maintain the overall stability of the leveling device.

[0047] Furthermore, an upper support seat 35 is connected to the upper end of the screw. The upper support seat 35 is matched with the upper end of the screw hole, allowing the upper end of the screw to pass through the screw hole first, and then the support seat to be welded above the screw hole. After leveling, the crossbeam 5 is supported on the upper support seat 35, which helps to maintain the overall stability of the leveling device.

[0048] It is understood that the upper and lower support bases are rectangular or circular structures to ensure a sufficiently large support area, which is beneficial to maintaining the overall stability of the leveling device.

[0049] In this embodiment, the length of the crossbeam support member is greater than the width of the crossbeam, and the length of the lower support member is greater than the width of the upper chord. This ensures that the welding area between the lower support member and the upper chord, and the welding area between the crossbeam support member and the crossbeam, achieves a reliable connection between the leveling device and the upper chord and crossbeam of the truss.

[0050] Specifically, the lower support member 2 and the crossbeam support member 1 are made of U-shaped steel. They can withstand high pressure, provide support for a long time, and are not easily deformed.

[0051] In the implementation of this utility model, the lower support member 2 is first fitted onto the upper chord 4, maintaining tight contact, and the lower support seat 34 is freely contacted on the upper surface of the upper chord. Next, the direction of the crossbeam support member 1 is controlled to be parallel to the crossbeam direction. If there is a certain distance between the upper support seat 35 and the bottom surface of the crossbeam 5, a wrench or other tool is used on the rotating section 32. The leveling member 3 rotates under force, and under the interaction of the screw 31 and the screw hole 12, the crossbeam support member 1 moves upward until it fits into the crossbeam 5. At this point, the device provides a leveling function. Finally, the lower support member is welded to the upper chord, and the crossbeam support member is welded to the crossbeam.

[0052] It is understandable that since the screw 31 and the screw hole 12 can provide structural support, and after leveling, the lower support 2 is welded to the upper chord 4 in the leveled state, and the crossbeam support 1 is welded to the crossbeam 5 in the leveled state, whether the upper support seat 35 is in contact with the lower surface of the crossbeam does not affect the support effect after construction.

[0053] Therefore, this leveling device can uniformly replace the leveling function under this construction condition and is applicable to various leveling distances; at the same time, it provides simple and easy-to-operate components, thereby reducing material and labor costs.

[0054] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
