Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station technology, and more specifically, to a photovoltaic support and photovoltaic array with a vibration damping mechanism. Background Technology

[0002] Once installed, existing photovoltaic modules are generally in a relatively stable structural state and do not pose any safety hazards to the modules, connectors, or supports.

[0003] However, when a photovoltaic field is located next to high-power equipment, the vibration energy of the equipment can be transmitted to the counterweight, bracket, and output cable joint of the photovoltaic module due to the large vibration of the equipment. This can lead to loosening of the bolts on the photovoltaic module clamp, loosening of the bracket, loosening of the module and slippage of the bracket, and poor photovoltaic module cable joints. In some cases, the joints may even spark and cause a fire, posing a safety hazard to people and equipment. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] The present invention provides a photovoltaic support with a vibration damping mechanism. The photovoltaic support with the vibration damping mechanism can absorb vibration energy by using a first vibration damping component located between the support and the frame and a second vibration damping component located at the bottom of the support, thereby reducing the vibration amplitude of the frame and reducing the risk of the frame falling off at the connection with the support. At the same time, the frame with a smaller vibration amplitude can keep the photovoltaic modules installed on it relatively stable, so as to ensure the stable connection of the output cable connector and reduce equipment safety hazards.

[0006] The photovoltaic support with vibration damping mechanism of this utility model embodiment includes: a frame for installing photovoltaic modules; a support for supporting the frame and the support includes a connecting surface and a supporting surface, the connecting surface being connected to the frame, the supporting surface being for contacting the ground, a first vibration damping element being provided between the connecting surface and the frame and / or a second vibration damping element being provided on the supporting surface.

[0007] This utility model discloses a photovoltaic support with a vibration damping mechanism. The frame is used to install photovoltaic modules, and the support is used to support the frame. The support includes a connecting surface and a supporting surface. The connecting surface is connected to the frame, and the supporting surface is used to contact the ground. A first vibration damping element is provided between the connecting surface and the frame, and / or a second vibration damping element is provided on the supporting surface. Thus, the first and second vibration damping elements can absorb vibration energy, reduce the vibration amplitude of the frame, and thereby reduce the risk of the frame falling off at the connection with the support. At the same time, the frame with a smaller vibration amplitude can keep the photovoltaic modules installed on it relatively stable, so as to ensure the stable connection of the output cable connector and reduce equipment safety hazards.

[0008] In some embodiments, the first damping element is a rubber pad and / or a damping spring.

[0009] In some embodiments, the support pier is connected to the frame by bolted connectors that pass through the first vibration damper.

[0010] In some embodiments, there are multiple bolted connectors arranged at intervals, and each bolted connector corresponds to one of the first vibration damping components.

[0011] In some embodiments, the bolted connector includes a connecting thread and a fixing nut, with each connecting thread corresponding to at least two fixing nuts.

[0012] In some embodiments, the rubber pad includes a plurality of stacked rubber pads.

[0013] In some embodiments, the connecting surface is provided with a mounting groove, and at least a portion of the first damping member is fitted into the mounting groove.

[0014] In some embodiments, the second damping element is a waterproof pad, which is laid on the support surface.

[0015] In some embodiments, the area of ​​the waterproof gasket is larger than the area of ​​the supporting surface.

[0016] The photovoltaic array of this utility model includes photovoltaic modules and a photovoltaic support with a vibration damping mechanism as described in the above embodiments.

[0017] The photovoltaic array of this utility model, by adopting the aforementioned photovoltaic modules, uses a frame for mounting the photovoltaic modules, and supports for supporting the frame. Each support includes a connecting surface and a supporting surface. The connecting surface is connected to the frame, and the supporting surface is used to contact the ground. A first vibration damping element is provided between the connecting surface and the frame, and / or a second vibration damping element is provided on the supporting surface. Thus, the first and second vibration damping elements can absorb vibration energy, reduce the vibration amplitude of the frame, and thereby reduce the risk of the frame falling off at the connection with the support. At the same time, the frame with a smaller vibration amplitude can keep the photovoltaic modules installed on it relatively stable, so as to ensure the stable connection of the output cable connector and reduce equipment safety hazards.

[0020] Frame 1; Support 2; First vibration damper 3; Second vibration damper 4; Bolted connector 5. Detailed Implementation

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figure 1 As shown, the photovoltaic support with vibration damping mechanism of this utility model includes a frame 1 and a support 2.

[0023] Specifically, the frame 1 is used to install photovoltaic modules, the support 2 is used to support the frame 1 and the support 2 includes a connecting surface and a supporting surface. The connecting surface is connected to the frame 1, the supporting surface is used to contact the ground, and a first vibration damping element 3 is provided between the connecting surface and the frame 1 and / or a second vibration damping element 4 is provided on the supporting surface.

[0024] It is understandable that when the vibration is transmitted to the support 2 and the frame 1, the first vibration damper 3 and the second vibration damper 4 can play the role of vibration damping and energy absorption, thereby reducing the vibration amplitude of the frame 1, reducing the risk of the connection between the frame 1 and the support 2 falling off, and ensuring the connection stability of the photovoltaic module output cable joint, thus eliminating potential safety hazards to the equipment.

[0025] The photovoltaic support with vibration damping mechanism of this utility model embodiment has a frame 1 for installing photovoltaic modules and a support 2 for supporting the frame 1. The support 2 includes a connecting surface and a supporting surface. The connecting surface is connected to the frame 1, and the supporting surface is used to contact the ground. A first vibration damping element 3 is provided between the connecting surface and the frame 1, and / or a second vibration damping element 4 is provided on the supporting surface. Thus, the first vibration damping element 3 and the second vibration damping element 4 can absorb vibration energy, reduce the vibration amplitude of the frame 1, and thereby reduce the risk of the frame 1 falling off at the connection with the support 2. At the same time, the smaller vibration amplitude of the frame 1 can keep the photovoltaic modules installed on it relatively stable, so as to ensure the stable connection of the output cable connector and reduce equipment safety hazards.

[0026] In some embodiments, the first damping element 3 is a rubber pad. It is understood that the rubber pad has a good damping effect on the one hand, and the material itself is a soft material, so it will not cause hard wear and damage to the surface of the frame 1 when in contact with the frame 1.

[0027] In some embodiments, the first damping element 3 is not limited to a rubber pad; for example, the first damping element 3 may also be a damping spring.

[0028] Furthermore, such as Figure 1 As shown, the support 2 is connected to the frame 1 by bolt connector 5, which passes through the first vibration damper 3. Specifically, as... Figure 1As shown, the first damping component 3 is a rubber pad, and the bolt connector 5 passes through the rubber pad. Thus, the bolt connector 5 can fix the rubber pad while fixing the frame 1 and the support 2, preventing the rubber pad from shifting or sliding due to external forces, and ensuring the assembly stability and reliability of the rubber pad.

[0029] Preferably, such as Figure 1 As shown, there are multiple bolt connectors 5 arranged at intervals, and each bolt connector 5 corresponds to a first vibration damper 3. It can be understood that the setting of multiple bolt connectors 5 can improve the connection reliability and avoid the problem of frame 1 falling off the support 2 due to the failure of a single connector. At the same time, the first vibration damper 3 corresponding to each bolt connector 5 can reduce vibration and absorb energy, resulting in a better overall vibration reduction effect.

[0030] In some embodiments, the bolted connector 5 includes a connecting thread and a fixing nut, with at least two fixing nuts corresponding to each connecting thread. For example... Figure 1 As shown, each connecting screw is equipped with double fixing nuts. Compared with a single nut, the double nuts can further reduce the probability of the nut falling off.

[0031] In some embodiments, the rubber pad includes multiple stacked rubber pads. Thus, the overall thickness of the rubber pad can be customized by selecting the number of rubber pads according to support and vibration damping requirements, allowing for flexible adaptation to different operating environments. For example, when the photovoltaic array is in a high-vibration environment, more rubber pads can be stacked to increase the overall thickness, thereby improving vibration damping capability; conversely, the number of rubber pads can be reduced to save costs.

[0032] Furthermore, an assembly groove is provided on the connecting surface, and at least a portion of the first damping component 3 fits into the assembly groove. Thus, the assembly groove can act as a limiting element in the assembly of the first damping component 3, improving its assembly reliability.

[0033] In some embodiments, the second damping element 4 is a waterproof gasket, which is laid on the support surface.

[0034] It should be noted that photovoltaic arrays are often installed on floors. By laying waterproof gaskets on the bottom of the support 2, we can avoid direct contact between the support 2 and the floor, thus protecting the floor. At the same time, because the waterproof gaskets have a perfect combination of rigidity and flexibility, they have a certain vibration absorption effect, thereby achieving vibration reduction.

[0035] Preferably, the area of ​​the waterproof gasket is larger than the area of ​​the supporting surface. Therefore, the waterproof gasket increases the stress-bearing area, reduces pressure, and protects the floor surface.

[0036] The photovoltaic array of this utility model embodiment includes photovoltaic modules and a photovoltaic support with a vibration damping mechanism as described in the above embodiment.

[0037] The photovoltaic array of this utility model adopts the photovoltaic support with the above-mentioned vibration damping mechanism. The frame 1 is used to install photovoltaic modules, and the support 2 is used to support the frame 1. The support 2 includes a connecting surface and a supporting surface. The connecting surface is connected to the frame 1, and the supporting surface is used to contact the ground. A first vibration damping element 3 is provided between the connecting surface and the frame 1 and / or a second vibration damping element 4 is provided on the supporting surface. Thus, the first vibration damping element 3 and the second vibration damping element 4 can absorb vibration energy, reduce the vibration amplitude of the frame 1, and reduce the risk of the frame 1 falling off at the connection with the support 2. At the same time, the smaller vibration amplitude of the frame 1 can keep the photovoltaic modules installed on it relatively stable, so as to ensure the stable connection of the output cable connector and reduce equipment safety hazards.
