Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic modules, and more specifically, to a shock-absorbing support structure for a photovoltaic bracket on a sloping roof. Background Technology

[0002] In residential photovoltaic (PV) sloping roof systems, the traditional approach involves connecting hooks to the existing structural beams, laying the tiles back on the hook base, and then bolting the sloping beam to the upper end of the hooks, with the hooks acting as supports. However, in certain locations, such as where there are no structural beams at the front eaves, the sloping beam can be excessively overhanging. To address this issue, without adding diagonal supports to the external walls, current technology involves adding a short column or long bolt of equal height to the hooks below the sloping beam, connecting it to a short crossbeam, and then placing the crossbeam on the tiles. However, under wind loads, the overhanging beam can deflect in both directions, causing vibrations in the supports and potentially leading to tile breakage.

[0003] In conclusion, how to prevent damage to the roof tiles under wind loads for power stations with extended cantilever beams is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a shock-absorbing support structure for a sloping roof photovoltaic bracket, which effectively avoids damage to the tiles under wind load.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibration damping support structure for a sloping roof photovoltaic bracket includes a short crossbeam suspended below a sloping beam. The short crossbeam is fixedly connected to the sloping beam, and a suspended gap is formed between the short crossbeam and the tiles below the sloping beam. The height of the suspended gap is adapted to the maximum deflection value of the sloping beam under wind load.

[0007] Preferably, the inclined beam is a U-shaped steel, and a first fixing structure is provided between the inclined beam and the short crossbeam to fix the short crossbeam to the inclined beam.

[0008] Preferably, the first fixing structure includes a first bolt disposed on the short crossbeam, and the first bolt is threadedly connected to the screw hole on the back side of the inclined beam.

[0009] Preferably, a first compensation component is provided between the short crossbeam and the inclined beam to make the height of the suspended space gap a set height.

[0010] Preferably, the first compensation component includes a plurality of first pads sleeved on the first bolt, the plurality of first pads being located between the short crossbeam and the inclined beam, and the first pads located at the ends respectively abutting against the end face of the short crossbeam and the end face of the inclined beam.

[0011] Preferably, the inclined beam is a C-shaped steel, and a second fixing structure is provided between the inclined beam and the short crossbeam to fix the short crossbeam to the inclined beam.

[0012] Preferably, the second fixing structure includes an angle steel disposed on the side of the inclined beam located at the screw hole, a second bolt is disposed on one side of the angle steel and threadedly connected to the screw hole on the back side of the inclined beam, and a third bolt is disposed on the other side of the angle steel and threadedly connected to the screw hole on the short crossbeam.

[0013] Preferably, a second compensation component is provided between the short crossbeam and the angle steel to make the height of the suspended space gap a set height.

[0014] Preferably, the second compensation component includes a plurality of second pads sleeved on the third bolt, the plurality of second pads being located between the short crossbeam and the angle steel, and the second pads located at the ends respectively abutting against the end face of the short crossbeam and the end face of the angle steel.

[0015] Preferably, the maximum deflection value of the inclined beam under wind load is less than the maximum deflection value of the inclined beam under snow load.

[0016] This utility model provides a shock-absorbing support structure for a sloping roof photovoltaic bracket. A short crossbeam is suspended below a sloping beam, and the two are fixedly connected. This fixed connection makes the short crossbeam and the sloping beam a relatively stable integrated structure. A cantilever gap is formed between the short crossbeam and the tiles below the sloping beam. The height of this cantilever gap is adapted to the maximum deflection value of the sloping beam under wind load. During installation, the maximum deflection value of the sloping beam under wind load is first determined, and then the position of the short crossbeam is adjusted accordingly to form a suitable cantilever gap between the short crossbeam and the tiles. In terms of working principle, when the sloping beam undergoes deflection changes under wind load, because the height of the cantilever gap is adapted to the maximum deflection value, the short crossbeam will not fall onto the tiles, avoiding damage to the tiles due to vibration and thus playing a role in shock absorption and tile protection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance.

This application discloses a vibration-damping support structure for a sloping roof photovoltaic bracket.

[0024] The core of this utility model is to provide a shock-absorbing support structure for a photovoltaic bracket on a sloping roof.

[0025] Please refer to Figures 1 to 2 .

[0026] The shock-absorbing support structure of the sloping roof photovoltaic bracket provided by this utility model includes a short crossbeam 2 suspended below the sloping beam 1. The short crossbeam 2 is fixedly connected to the sloping beam 1. A suspended space gap is formed between the short crossbeam 2 and the tiles below the sloping beam 1. The height of the suspended space gap is adapted to the maximum deflection value of the sloping beam 1 under wind load.

[0027] Specifically, the short crossbeam 2 is suspended below the inclined beam 1, and the two are fixedly connected. This fixed connection makes the short crossbeam 2 and the inclined beam 1 a relatively stable integral structure. A cantilever gap is formed between the short crossbeam 2 and the tile below the inclined beam 1. The height of this cantilever gap is adapted to the maximum deflection value of the inclined beam 1 under wind load. During installation, the maximum deflection value of the inclined beam 1 under wind load is first determined, and then the position of the short crossbeam 2 is adjusted accordingly to form a suitable cantilever gap between the short crossbeam 2 and the tile. This ensures that the short crossbeam 2 will not fall onto the tile when the inclined beam 1 is subjected to wind load. When the inclined beam 1 deflects under wind load, the short crossbeam 2 will not fall onto the tile because the height of the cantilever gap is adapted to the maximum deflection value, thus avoiding damage to the tile due to vibration and playing a role in shock absorption and protection of the tile. At the same time, this arrangement of the short crossbeam 2 eliminates the need to place it on the tile, reducing the pressure on the tile and the risk of breakage due to vibration.

[0028] The aforementioned shock-absorbing support structure for the sloping roof photovoltaic bracket effectively solves the problem of the positive and negative deflection of the sloping beam 1 under wind load causing the support to vibrate and break the tiles. It reserves space for the deflection of the cantilevered sloping beam 1, resists wind load, protects the tiles, and achieves a shock-absorbing effect.

[0029] It should be noted that this application can also be used to install snow nets on existing power plants. Installing such snow nets requires extending the inclined beam 1 on-site, which can lead to excessive cantilever length of the inclined beam 1. Furthermore, snow-blocking components are typically installed in this situation. When snow begins to accumulate on the components, the snow-blocking device activates, and the excessive snow load causes the inclined beam 1 to bend downwards. Therefore, the maximum deflection of the inclined beam 1 under wind load is less than the maximum deflection of the inclined beam 1 under snow load. That is, the local basic snow pressure should be greater than the basic wind pressure, so that the deflection generated by the snow load will be greater than the deflection under the wind load. This ensures that the short crossbeam 2 only rests on the roof tiles under snow load. If the deflection of the inclined beam 1 increases due to snow load, the short crossbeam 2 can provide some support.

[0030] The shock-absorbing support structure for the sloping roof photovoltaic bracket provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0031] The short crossbeam 2 includes the beam body. The beam body is typically made of metal, such as steel, which offers high strength and stability; alternatively, high-strength alloy materials can be used. The beam body is generally elongated for ease of installation and support. The inclined beam 1 includes the beam body and screw holes. The beam body can be made of U-shaped or C-shaped steel, depending on the specific requirements. U-shaped steel beams offer better load-bearing capacity and stability, and their open structure facilitates the installation and fixing of other components. C-shaped steel beams offer advantages such as light weight and easy installation. Screw holes are located on the beam body for connection to the connecting components of the short crossbeam 2. The size and spacing of the screw holes are designed according to specific connection requirements.

[0032] In one specific embodiment, when the inclined beam 1 is a U-shaped steel, refer to Figure 1 A first fixing structure is provided between the inclined beam 1 and the short crossbeam 2 to fix the short crossbeam 2 and the inclined beam 1.

[0033] Specifically, a first fixed structure is set between the inclined beam 1 and the short crossbeam 2 to achieve a fixed connection between the two, which enables the short crossbeam 2 to be stably suspended below the inclined beam 1, forming a suspended space gap that matches the maximum deflection value of the inclined beam 1 under wind load. This prevents the short crossbeam 2 from hitting the tiles under wind load, thus resisting wind load, protecting the tiles, and reducing shock. At the same time, the short crossbeam 2 can also play a supporting role under snow load.

[0034] Furthermore, the first fixing structure includes a first bolt 3 disposed on the short crossbeam 2, and the first bolt 3 is threadedly connected to the screw hole on the back side of the inclined beam 1.

[0035] Specifically, the first fixing structure includes a first bolt 3 mounted on the short crossbeam 2, which is threadedly connected to a screw hole on the back side of the inclined beam 1. The first bolt 3 is generally made of high-strength metal, such as stainless steel, which has good corrosion resistance and fastening performance. The head shape of the first bolt 3 varies, with common types including hexagonal head, round head, and countersunk head. In this embodiment, a suitable head shape can be selected according to the actual installation situation.

[0036] In other embodiments, the first fixing structure may also include other structural forms besides the first bolt 3, such as a specially designed clamp that surrounds the inclined beam 1 and the short crossbeam 2, and the two are fixedly connected by tightening the bolts on the clamp. The specially designed clamp may be made of high-strength carbon steel and galvanized to enhance corrosion resistance.

[0037] Based on any of the above embodiments, refer to Figure 1 A first compensation component is provided between the short crossbeam 2 and the inclined beam 1 so that the height of the suspended space gap is the set height.

[0038] Specifically, by setting a first compensation component between the short crossbeam 2 and the inclined beam 1, the distance between the two can be adjusted, thereby making the height of the suspended space gap formed between the short crossbeam 2 and the tile below the inclined beam 1 reach the set height, which is adapted to the maximum deflection value of the inclined beam 1 under wind load, and prevents the short crossbeam 2 from hitting the tile under wind load.

[0039] Furthermore, the first compensation component includes a plurality of first pads sleeved on the first bolt 3. The plurality of first pads are located between the short crossbeam 2 and the inclined beam 1, and the first pads located at the ends respectively abut against the end face of the short crossbeam 2 and the end face of the inclined beam 1.

[0040] Specifically, the first compensation component includes multiple first pads fitted onto the first bolt 3. These first pads are located between the short crossbeam 2 and the inclined beam 1, with the end pads respectively abutting against the end faces of the short crossbeam 2 and the inclined beam 1. The first pads can be made of materials such as rubber or plastic, possessing a certain degree of elasticity and cushioning performance. First pads of different thicknesses can be used in combination. By adjusting the number and thickness of the first pads, the height of the suspension gap can be precisely controlled to match the maximum deflection value of the inclined beam 1 under wind load.

[0041] In other embodiments, the first compensation component may further include an elastic washer, which may be made of rubber, installed between the short crossbeam 2 and the inclined beam 1, and adjusts the height of the cantilever gap through its own elastic deformation. Alternatively, a telescopic member with an adjustable length may be used as the first compensation component, and the height of the cantilever gap can be adjusted by adjusting the length of the telescopic member.

[0042] In one specific embodiment, when the inclined beam 1 is a C-shaped steel, refer to Figure 2 A second fixing structure is provided between the inclined beam 1 and the short crossbeam 2 to fix the short crossbeam 2 to the inclined beam 1.

[0043] Specifically, when the inclined beam 1 is a C-shaped steel, the second fixing structure can fix the short crossbeam 2 to the inclined beam 1, thereby ensuring that a suitable suspension gap is formed between the short crossbeam 2 suspended below the inclined beam 1 and the tile below the inclined beam 1 to resist wind load and prevent the short crossbeam 2 from hitting the tile under wind load. At the same time, the short crossbeam 2 can play a supporting role under snow load.

[0044] Furthermore, the second fixing structure includes an angle steel 4 located on the side of the inclined beam 1 with screw holes. A second bolt 5 is provided on one side of the angle steel 4 and is threadedly connected to the screw holes on the back side of the inclined beam 1. A third bolt 6 is provided on the other side of the angle steel 4 and is threadedly connected to the screw holes on the short crossbeam 2.

[0045] Specifically, the second fixing structure includes an angle steel 4 located on the side of the inclined beam 1 near the screw hole. A second bolt 5 is installed on one side of the angle steel 4 and threadedly connected to the screw hole on the back side of the inclined beam 1. A third bolt 6 is installed on the other side of the angle steel 4 and threadedly connected to the screw hole on the short crossbeam 2. The angle steel 4 is generally an equilateral angle steel, mostly made of steel, which has high strength and stability. The second bolt 5 and the third bolt 6 are also high-strength metal bolts, and their specifications and models are selected according to the connection requirements between the angle steel 4 and the inclined beam 1 and the short crossbeam 2.

[0046] In other embodiments, the second fixing structure may also include using a connector to rivet the inclined beam 1 and the short crossbeam 2 together. The connector may be made of copper, which has good toughness and can ensure the stability of the connection.

[0047] Based on any of the above embodiments, refer to Figure 2 A second compensation component is provided between the short crossbeam 2 and the angle steel 4 to make the height of the suspended space gap the set height.

[0048] Specifically, by setting a second compensation component between the short crossbeam 2 and the angle steel 4, the distance between the two can be adjusted, thereby making the height of the suspended space gap formed between the short crossbeam 2 and the tile below the inclined beam 1 reach the set height, which is adapted to the maximum deflection value of the inclined beam 1 under wind load, and prevents the short crossbeam 2 from hitting the tile under wind load.

[0049] Furthermore, the second compensation component includes a plurality of second pads fitted onto the third bolt 6. The plurality of second pads are located between the short crossbeam 2 and the angle steel 4, and the second pads located at the ends respectively abut against the end face of the short crossbeam 2 and the end face of the angle steel 4.

[0050] Specifically, the second compensation component includes multiple second shims fitted onto the third bolt 6. These second shims are located between the short crossbeam 2 and the angle steel 4, with the end shims respectively abutting against the end faces of the short crossbeam 2 and the angle steel 4. The material and function of the second shims are similar to those of the first shims. By adjusting the number and thickness of the second shims, the height of the cantilever gap can be ensured to meet the design requirements.

[0051] In other embodiments, the second compensation component may also include a disc spring with variable stiffness characteristics, which is sleeved on the third bolt 6 and precisely controls the height of the suspension gap by changing its compression.

[0052] It should also be noted that the short crossbeam 2 can be replaced by some damping structures, including damping springs and support plates. Damping springs are generally helical springs, usually made of alloy steel, which have good elasticity and damping performance. The support plate is made of steel plate or high-strength plastic plate, and its shape can be square, round, etc. One end of the damping spring is connected to the inclined beam 1, and the other end is connected to the support plate. The support plate is close to the tile but not in contact with it, and the expansion and contraction of the damping spring adapts to the deflection changes of the inclined beam 1.

[0053] Replacing the short crossbeam 2 with a vibration-damping structure better absorbs and buffers the vibrations generated by the inclined beam 1 under wind and snow loads, further improving the protection of the roof tiles. Although the cost is relatively high, it is more suitable for applications with high vibration damping requirements. Compared with traditional support methods and the short crossbeam 2 support method in the above embodiment, it has a greater improvement in vibration damping performance, providing more options for the support of sloping roof photovoltaic systems and meeting the needs of different users.

[0054] The implementation principle of the vibration damping support structure for a sloping roof photovoltaic bracket in this application embodiment is as follows: This vibration damping support structure suspends a short crossbeam 2 below and fixes it to the sloping beam 1. The suspended gap adapts to the maximum deflection value of the sloping beam 1 under wind load, effectively preventing damage to the tiles under wind load by the short crossbeam 2, thus achieving vibration damping and tile protection. Simultaneously, the first fixing structure, the second fixing structure, and corresponding compensation components ensure reliable connection between the short crossbeam 2 and different types of sloping beams 1, and precise control of the suspended gap height. Furthermore, by utilizing the deflection difference caused by snow load and wind load, the short crossbeam 2 can support the sloping beam 1 under snow load, solving the problem of excessively long cantilevered sloping beam 1, reducing construction difficulty, and lowering costs, representing a significant improvement and enhancement compared to existing technologies.
