Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel frame technology, specifically relating to a stability testing device for the construction of agricultural photovoltaic panel frames. Background Technology

[0002] With the ever-increasing global demand for clean energy, the development and utilization of solar energy are receiving increasing attention. In the agricultural sector, the innovative model of agricultural photovoltaics is gradually emerging. It combines photovoltaic power generation with agricultural production, achieving efficient and diversified land use. As a fundamental industry of the nation, agriculture is also constantly seeking integration and development with emerging technologies. The emergence of the agricultural photovoltaic model not only allows for photovoltaic power generation during agricultural production, increasing land productivity, but also provides some power support for agricultural production, promoting the modernization of agriculture.

[0003] However, agricultural photovoltaic panel frames are typically installed in vast outdoor farmlands, in environments that are complex and variable. These frames must withstand the long-term effects of various natural factors, such as wind forces of varying intensities and directions, which can exert continuous thrust and bending moments; temperature changes causing thermal expansion and contraction of materials, affecting the tightness of the frame's connections; variations in farmland geological conditions, such as soil looseness and moisture content, can lead to uneven settlement of the frame's foundation; furthermore, substandard installation quality, such as weak welding or loose bolts, can also compromise the frame's stability.

[0004] In the past, the methods for testing the stability of photovoltaic panel frames were relatively simple and rudimentary. In some cases, it relied solely on the visual inspection of the frame by workers to check for obvious deformation, cracks, or loosening. This method is highly subjective and easily overlooks minor but critical issues. Sometimes, the stability was judged by simply manually shaking the frame, but this method cannot apply accurate force and is difficult to simulate the complex stress conditions in real-world environments. Furthermore, limited mechanical testing may only target individual parts or specific directions of the frame, failing to comprehensively cover the stress conditions under different operating conditions.

[0005] To address this, we propose a stability testing device for agricultural photovoltaic (PV) panel frame construction. This device can be equipped with adjustable pressure plates and pressure alarms on the inclined and vertical surfaces of the PV frame, enabling precise pressure application and displacement detection at different locations. This allows for a comprehensive assessment of the frame's stability, resulting in more accurate and reliable test results. Furthermore, it can adapt to PV frames of various sizes and shapes, thus expanding its application range. Utility Model Content

[0006] The purpose of this invention is to provide a stability testing device for agricultural photovoltaic panel frame construction. This device can be equipped with adjustable pressure plates and pressure alarms on the inclined and vertical surfaces of the photovoltaic frame, respectively. It can accurately apply pressure and detect displacement at different locations, comprehensively evaluate the stability of the frame, and provide more accurate and reliable test results. At the same time, it can adapt to photovoltaic frames of various sizes and shapes, thus expanding its application range.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A stability testing device for agricultural photovoltaic panel frame construction includes a testing platform and a photovoltaic frame installed on the testing platform. The testing platform has a first slide groove, a second slide groove, and a T-shaped support rod. A first rotating assembly is provided inside the first slide groove. A first movable plate is provided on the first rotating assembly. A first connecting rod is provided on the first movable plate. A first pressing plate that fits against the inclined surface of the photovoltaic frame is hinged to the end of the first connecting rod away from the first movable plate. A second rotating assembly is provided inside the second slide groove. A second movable plate is provided on the second rotating assembly. A second connecting rod is provided on the second movable plate. A second pressing plate that fits against the vertical surface of the photovoltaic frame is installed at the end of the second connecting rod away from the second movable plate.

[0009] The T-shaped support rod is located between the inclined surface of the photovoltaic frame and the vertical surface of the photovoltaic frame, and both ends of the T-shaped support rod are equipped with length adjustment components, and the length adjustment components are equipped with two pressure alarms.

[0010] Furthermore, the first rotating assembly includes a first motor disposed on the detection table, the output end of the first motor is equipped with a first threaded rod located inside the first slide groove, and a first threaded sleeve connected to the first movable plate is sleeved on the first threaded rod.

[0011] Furthermore, the second rotating assembly includes a second motor disposed on the detection table, and the output end of the second motor is equipped with a second threaded rod located inside the second slide groove. A second threaded sleeve connected to the second movable plate is sleeved on the second threaded rod.

[0012] Furthermore, the length adjustment assembly includes a hollow shell disposed within the T-shaped support rod. Inside the hollow shell are a first connecting plate, a second connecting plate, and a gear. The first connecting plate and the second connecting plate are symmetrically arranged, and meshing teeth are provided on the sides of the first connecting plate and the second connecting plate that are close to each other. A gear is disposed between two meshing teeth and meshes with them. Sliding plates are provided at both ends of the first connecting plate and the second connecting plate, and the pressure alarm is fixedly hinged to one side of each sliding plate.

[0013] Furthermore, the gear is provided with a rotating rod, one end of which extends through the hollow shell and is fitted with a rotating disk. The rotating disk has multiple locking holes. The hollow shell is provided with a fixing block, which has a through hole. A movable rod is provided inside the through hole. A limit plate is provided at the top of the movable rod, and a locking rod located inside the locking hole is provided at the bottom of the movable rod. A spring is sleeved on the movable rod, one end of which is connected to the limit plate, and the other end of which is connected to the fixing block.

[0014] Furthermore, the locking lever matches the locking hole.

[0015] The technical effects achieved by this utility model are as follows:

[0016] First, during stability testing, the photovoltaic (PV) frame is mounted on the testing platform. The position of the pressure alarms is adjusted using a length adjustment component, ensuring one alarm aligns with the inclined surface of the PV frame and the other with its vertical surface. This accommodates PV frames of different sizes. Then, a first rotating component drives a first movable plate, causing a first connecting rod to contact a first pressing plate. Due to the hinged design, the first pressing plate aligns with the inclined surface of the PV frame. Simultaneously, a second rotating component drives a second movable plate, causing a second connecting rod to contact a second pressing plate with the vertical surface of the PV frame. After preparation, the first and second rotating components respectively apply pressure to the PV frame using the first and second pressing plates, simulating wind force. The magnitude and direction of the thrust can be set and adjusted according to actual conditions. When the first pressing plate is subjected to thrust, the force is transmitted to the inclined surface of the PV frame. If the structural strength of the PV frame at this location is insufficient or the connection is not stable enough, a slight displacement will occur. This displacement will compress the pressure alarm in contact with it, and the pressure sensor inside the alarm will detect the pressure change in real time. Once the pressure exceeds a preset threshold, the pressure alarm will immediately issue an audible and visual alarm signal, alerting the inspector that there is a problem with the stability of the photovoltaic frame at that inclined surface. Similarly, when a pushing force is applied to the second pressing plate, the force is transmitted to the vertical surface of the photovoltaic frame. If displacement occurs in the vertical surface, causing the pressure alarm to exceed the threshold, it will also trigger an alarm. This device can be equipped with adjustable pressing plates and pressure alarms on the inclined and vertical surfaces of the photovoltaic frame, respectively. It can accurately apply pressure and detect displacement at different locations, comprehensively assessing the stability of the frame. The detection results are more accurate and reliable, and it can adapt to photovoltaic frames of various sizes and shapes, expanding its application range. Attached Figure Description

[0024] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, the specific technical solution adopted in this utility model is as follows: A stability testing device for agricultural photovoltaic panel frame construction includes a testing platform 1 and a photovoltaic frame 2 installed on the testing platform 1. The testing platform 1 is provided with a first sliding groove 3, a second sliding groove 4 and a T-shaped support rod 5. A first rotating component is provided inside the first sliding groove 3. A first movable plate 6 is provided on the first rotating component. A first connecting rod is provided on the first movable plate 6. A first pressing plate 7 that is in contact with the inclined surface of the photovoltaic frame 2 is hinged to the end of the first connecting rod away from the first movable plate 6. A second rotating component is provided inside the second sliding groove 4. A second movable plate 8 is provided on the second rotating component. A second connecting rod is provided on the second movable plate 8. A second pressing plate 9 that is in contact with the vertical surface of the photovoltaic frame 2 is installed at the end of the second connecting rod away from the second movable plate 8.

[0026] The T-shaped support rod 5 is located between the inclined surface of the photovoltaic frame 2 and the vertical surface of the photovoltaic frame 2, and both ends of the T-shaped support rod 5 are equipped with length adjustment components, and two pressure alarms 10 are installed on the length adjustment components.

[0027] The photovoltaic frame 2 is connected to the testing platform 1 by bolts, which facilitates the installation and disassembly of the photovoltaic frame 2.

[0028] Meanwhile, the first rotating assembly includes a first motor 11 mounted on the testing table 1. The output end of the first motor 11 is equipped with a first threaded rod 12 located inside the first slide groove 3. A first threaded sleeve 13 connected to the first movable plate 6 is fitted on the first threaded rod 12.

[0029] The first motor 11 drives the first threaded rod 12 to rotate, and the first threaded rod 12 drives the first movable plate 6 to move. When pressure is applied, the speed of the first motor 11 can be adjusted to apply pressure.

[0030] The second rotating assembly includes a second motor 14 mounted on the detection table 1. The output end of the second motor 14 is equipped with a second threaded rod 15 located inside the second slide groove 4. A second threaded sleeve 16 connected to the second movable plate 8 is fitted on the second threaded rod 15.

[0031] The second motor 14 drives the second threaded rod 15 to rotate, and the second threaded rod 15 drives the second movable plate 8 to move. When pressure is applied, the speed of the first motor 11 can be adjusted to apply pressure.

[0032] It should be noted that both the first motor 11 and the second motor 14 are variable speed motors, specifically YVP variable frequency speed control motors. These motors, when used in conjunction with a frequency converter, achieve smooth stepless speed regulation. They are suitable for applications requiring precise speed control, offer high efficiency and reliability, and are existing technologies, so further details will not be provided here.

[0033] The T-shaped support rod 5 is a telescopic rod, and its telescopic mechanism may be similar to that of an umbrella bracket rod. The length can be adjusted through an internal sliding or sleeve structure, and it may be equipped with a locking device to fix the required length. This is existing technology and will not be elaborated on here. This setting allows for the detection of different positions of the photovoltaic frame 2, thereby improving the comprehensiveness of the detection.

[0034] The length adjustment assembly includes a hollow housing 17 disposed in the T-shaped support rod 5. Inside the hollow housing 17 are a first connecting plate 18, a second connecting plate 19, and a gear 20. The first connecting plate 18 and the second connecting plate 19 are symmetrically arranged, and each of the first connecting plate 18 and the second connecting plate 19 has a meshing tooth 21 on one side that is close to each other. A gear 20 is disposed between the two meshing teeth 21 and meshes with them. Sliding plates 22 are disposed at both ends of the first connecting plate 18 and the second connecting plate 19. A pressure alarm 10 is fixedly hinged to one side of each sliding plate 22.

[0035] By rotating gear 20, gear 20 drives meshing teeth 21 to make the first connecting plate 18 and the second connecting plate 19 move relative to or in opposite directions, thereby driving the two sliding plates 22 to move. This allows the distance of the pressure alarm 10 to be adjusted to accommodate photovoltaic frame 2 of different sizes.

[0036] It should be noted that a fixed hinge refers to connecting two or more components at a certain point or area through a specific structure and method, so that they can rotate relative to each other but remain in a fixed connection state. In this utility model, the pressure alarm 10 will keep the angle unchanged when the angle changes, which facilitates detection. This utility model uses bolts for hinge, which can keep the angle fixed when it changes and will not change. This is existing technology and will not be described in detail here.

[0037] A rotating rod is provided on the gear 20. One end of the rotating rod passes through the hollow shell 17 and is mounted on a rotating disk 23. Multiple locking holes 24 are provided on the rotating disk 23. A fixing block 25 is provided on the hollow shell 17. A through hole is provided on the fixing block 25. A movable rod 26 is provided inside the through hole. A limit plate is provided at the top of the movable rod 26. A locking rod 27 located inside the locking hole 24 is provided at the bottom of the movable rod 26. A spring 28 is sleeved on the movable rod 26. One end of the spring 28 is connected to the limit plate, and the other end of the spring 28 is connected to the fixing block 25.

[0038] First, the limiting plate drives the movable rod 26 to pull the locking rod 27 out of the locking hole 24, thereby causing the rotating plate 23 to drive the rotating rod to rotate the gear 20, thus adjusting the length. After the adjustment is completed, the spring force of the spring 28 causes the locking rod 27 to enter the locking hole 24 for locking.

[0039] The pressure alarm 10 mainly consists of four parts: a sensor, an electrical signal converter, a processor, and an alarm circuit. The sensor is responsible for monitoring pressure changes inside the system and converting the pressure value into an electrical signal.

[0040] Electrical signal converter: Converts the electrical signals output by the sensor into standard signals for processing by the processor.

[0041] Processor: Processes and records the converted signal, and determines whether the current pressure is normal based on the set pressure range.

[0042] Alarm circuit: When the processor detects abnormal pressure, it sends out an audible and visual alarm signal through the alarm circuit.

[0043] The working principle of the pressure alarm 10 is to output an alarm signal by measuring the pressure value inside the system. The specific process is as follows: when the pressure value inside the system changes, the sensor will detect this change and convert the pressure value into an electrical signal output.

[0044] An electrical signal converter receives electrical signals output by a sensor and converts them into standard signals that a processor can recognize.

[0045] The processor processes and records the converted signal, while comparing it with the set pressure range.

[0046] If the current pressure value exceeds the set normal range, the processor will immediately issue an audible and visual alarm signal through the alarm circuit to remind staff to take appropriate measures in a timely manner.

[0047] The pressure alarm 10 is model number Euro digital display pressure alarm 10, which is existing technology and will not be discussed in detail here.

[0048] The locking lever 27 is matched with the locking hole 24, which allows the locking lever 27 to enter or be pulled out of the locking hole 24.

[0049] The working principle of this utility model is as follows: First, during stability testing, the photovoltaic frame 2 is installed on the testing platform 1. At this time, the position of the pressure alarm 10 is adjusted using the length adjustment component, so that one pressure alarm 10 is in contact with the inclined surface of the photovoltaic frame 2, and the other pressure alarm 10 is in contact with the vertical surface of the photovoltaic frame 2. This accommodates photovoltaic frames 2 of different sizes. Then, the first rotating component drives the first movable plate 6, causing the first connecting rod to contact the first pressing plate 7. Due to its hinged design, the first pressing plate 7 is in contact with the inclined surface of the photovoltaic frame 2. Simultaneously, the second rotating component drives the second movable plate 8, causing the second connecting rod to contact the second pressing plate 9 with the vertical surface of the photovoltaic frame 2. After preparation, the first and second rotating components respectively drive the first pressing plate 7 and the second pressing plate 9 to apply pressure to the photovoltaic frame 2, simulating wind force in nature. The magnitude and direction of the thrust can be set and adjusted according to actual conditions. When the first pressing plate 7 is subjected to thrust, the force is transmitted to the inclined surface of the photovoltaic frame 2. If the structural strength of the photovoltaic frame 2 at this position is insufficient or the connection is not stable enough, a slight displacement will occur. This displacement will cause the pressure alarm 10 in contact with it to be squeezed, and the pressure sensor inside the pressure alarm 10 will detect the pressure change in real time. Once the pressure exceeds the preset threshold, the pressure alarm 10 will immediately issue an audible and visual alarm signal, prompting the inspector that there is a problem with the stability of the photovoltaic frame 2 at the inclined surface. Similarly, when a pushing force is applied to the second pressing plate 9, the force is transmitted to the vertical surface of the photovoltaic frame 2. If the vertical surface is displaced, causing the pressure alarm 10 to be pressed beyond the threshold, an alarm will also be triggered. This device can be equipped with adjustable pressing plates and pressure alarms 10 on the inclined and vertical surfaces of the photovoltaic frame 2, respectively, enabling precise pressure application and displacement detection at different locations, comprehensively assessing the stability of the frame, and providing more accurate and reliable detection results. At the same time, it can adapt to photovoltaic frames 2 of various sizes and shapes, expanding the application range.

[0050] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
