Currently, monitoring methods for photovoltaic support systems are relatively limited, and data collection is not convenient, accurate, or efficient enough, making it difficult to detect potential problems such as structural deformation and support displacement in a timely manner, thus affecting the normal operation and service life of photovoltaic power plants. Utility Model Content

[0003] This utility model aims to provide a photovoltaic support structure monitoring data acquisition instrument to solve the problems existing in the monitoring of photovoltaic support structures in the prior art. To achieve the above objective, this application provides the following technical solution: a photovoltaic support structure monitoring data acquisition instrument, comprising:

[0004] The sensor body includes a pull-rope transmission device, a sensing component, a signal processing circuit, an output interface, and a housing. The pull-rope transmission device is used to convert the displacement of the measured object into the extension and retraction of the pull rope. The sensing component is used to convert the extension and retraction of the pull rope into an electrical signal. The signal processing circuit is used to process the electrical signal output by the sensing component. The output interface is used to output the processed signal to an external device. The housing is used to protect the various components inside the sensor body and to connect with other components.

[0005] The slide rail is disposed on the side wall of the housing, and a matching slide piece is disposed on the slide rail. The slide piece is U-shaped on both sides and is provided with mounting holes. The slide piece can be fixed to a specific position on the slide rail by tightening the bolts.

[0006] The clamping mechanism includes a connecting seat, clamping blocks, and elastic plates. The two ends of the connecting seat are fixedly connected to the sliding plate by bolts. The two clamping blocks are hinged in the connecting seat, and the side wall of the clamping block is provided with a groove to accommodate the elastic plate. The elastic plate provides clamping force to realize the positioning of the data acquisition instrument by the clamping mechanism.

[0007] In a preferred embodiment of this technical solution, a clamping piece is also included. The clamping piece is arc-shaped with hooks at both ends. It is disposed at the ends of the clamping blocks and connects and locks the two clamping blocks together.

[0008] In a preferred embodiment, this technical solution further includes a connecting post and a pin. The connecting post is disposed at the end of the pull rope in the pull rope transmission device, and the side of the connecting post has a limiting hole for accommodating the pin through which it passes.

[0009] In a preferred embodiment, this technical solution also includes a gasket, which is disposed on the connecting post to assist in the connection between the connecting post and other structures, thereby achieving the fixation of the pull rope.

[0027] In order to solve the technical problems in the background art, such as Figure 1-5 As shown, this application provides a technical solution: a photovoltaic support structure monitoring data acquisition instrument, characterized as follows:

[0028] Sensor body 1 is the core component of the entire data acquisition instrument, and its structure is as follows: Figure 2As shown, the device includes a pull rope transmission device 2, a sensing component 3, a signal processing circuit 4, an output interface 5, and a housing 6. The pull rope transmission device 2 mainly consists of a pull rope, a transmission wheel, and a spring. One end of the pull rope is fixed to the object being measured, and the other end passes around the transmission wheel and is connected to the spring. Its function is to convert the displacement of the object being measured into the extension and contraction of the pull rope. For example, when the photovoltaic support structure is displaced, the pull rope will extend or shorten accordingly, thereby realizing the initial conversion of the displacement signal. The sensing component 3 usually uses a high-precision strain gauge or displacement sensor, which is installed on the spring of the pull rope transmission device (2) and can convert the extension and contraction of the spring into an electrical signal. When the pull rope extends or contracts, the sensing component 3 can convert the extension and contraction of the pull rope into an electrical signal. The signal processing circuit 4 is a rectangular circuit board installed inside the housing 6 and connected to the sensing component 3 through a wire. Its main function is to process the electrical signal output by the sensing component 3, including filtering, amplification, and other operations, to improve the quality and stability of the signal and make it easier for subsequent transmission and analysis. The output interface 5 is a USB interface installed on the side of the housing 6 and connected to the signal processing circuit 4. Its function is to output the processed signal to external devices, such as computers and monitoring systems, so as to further process and analyze the monitoring data of the photovoltaic support structure. The outer shell 6 is made of high-strength, corrosion-resistant material and has good sealing performance to protect the internal components from the influence of the external environment. The internal space of the outer shell 6 is used to accommodate components such as the pull rope transmission device 2, sensing component 3, signal processing circuit 4 and output interface 5. At the same time, the side wall of the outer shell 6 is also provided with a slide rail 7 for connecting and fixing with other components. The slide rail 7 is long and strip-shaped and welded to the side wall of the outer shell 6. Its cross-section is T-shaped. The slide rail 7 provides a sliding track for the slide plate (8) to realize the positioning and fixing of the slide plate (8). The slide rail 7 is provided with a matching slide plate 8. The two sides of the slide plate 8 are U-shaped structures, the middle part is thinner and the two sides are thicker, and the thicker parts on both sides are provided with mounting holes 9. By passing bolts through the mounting holes 9 and tightening them, the slide plate 8 can be fixed in a specific position on the slide rail 7. The clamping mechanism 10, used for positioning the data acquisition instrument, includes a connecting seat 11, clamping blocks 12, and elastic plates 13. The connecting seat 11 is a rigid structure, with both ends fixedly connected to the sliding plate 8 by bolts, thus fixing the clamping mechanism 10 to the slide rail 7. There are two semi-circular clamping blocks 12, each hinged to the inner wall of one side of the connecting seat 11. Grooves are provided on the side walls of the clamping blocks 12 to accommodate the elastic plates 13. The clamping and positioning of the data acquisition instrument are achieved through the hinges and the elastic force of the elastic plates 13. The elastic plates 13 are elongated strips made of spring steel, possessing good elasticity and toughness. The elastic plates 13 are installed in the grooves of the clamping blocks 12, providing clamping force to bring the two clamping blocks 12 closer together, thereby enabling the clamping mechanism 10 to firmly clamp other mechanisms and ensure the stability of the data acquisition instrument's position during monitoring.

[0029] In this embodiment, through the design of the above structure, the photovoltaic support structure monitoring data acquisition instrument can realize displacement monitoring of the photovoltaic support structure. When the photovoltaic support structure is displaced, the pull rope transmission device 2 converts the displacement into the extension and retraction of the pull rope, the sensing component 3 converts the extension and retraction of the pull rope into an electrical signal, the signal processing circuit 4 processes the electrical signal, and finally outputs the processed signal to an external device through the output interface 5. At the same time, the design of the slide rail 7 and the slider 8 allows the installation position of the data acquisition instrument to be flexibly adjusted, and the clamping mechanism 10 can ensure the stable positioning of the data acquisition instrument, thereby improving the accuracy and reliability of monitoring.

[0030] Furthermore, the clamping piece 14 is arc-shaped with hook-like structures at both ends. This design allows the clamping piece 14 to better conform to the surface of the object being clamped, providing a more uniform clamping force. The hook-like structure design allows the clamping piece 14 to firmly hook onto the end of the clamping block 12 and embed into the groove of the clamping block 12, ensuring that it will not loosen during clamping. The clamping piece 14 is located at the end of the clamping block 12, and the two clamping blocks 12 are connected and locked together by the hook-like structures at both ends. When the two clamping blocks 12 are close together, the clamping piece 14 can firmly connect them together, further enhancing the clamping effect of the clamping mechanism 10.

[0031] It should be noted that the connecting post 15 is cylindrical and is located at the end of the pull rope in the pull rope transmission device 2. The pull rope passes through the hook at the bottom of the connecting post 15 for fixation. A limiting hole is provided on the side of the connecting post 15, the shape and size of which match the pin 16. The pin 16 is cylindrical, with a diameter slightly smaller than the diameter of the limiting hole to allow it to pass smoothly through. The connecting post 15 is connected to the pin 16 through the limiting hole on its side. The pin 16 passes through the limiting hole, fixing the connecting post 15 to the photovoltaic support to be monitored. This connection method allows the pull rope to be connected to the external object being measured via the connecting post 15, while ensuring the stability and reliability of the connection.

[0032] Furthermore, the gasket 17 is a thin, circular or square sheet structure with moderate thickness, possessing a certain degree of elasticity and toughness, serving as a buffer and compensation mechanism. The gasket 17 is positioned on the connecting post 15, specifically between the connecting post 15 and the pin 16, or between the connecting post 15 and the object being measured. Through its own elasticity and toughness, the gasket 17 assists in the connection between the connecting post 15 and other structures, ensuring the tightness and stability of the connection. The main function of the gasket 17 is to assist in the connection between the connecting post 15 and other structures, thereby securing the pull rope. By placing the gasket 17 on the connecting post 15, the tightness and stability of the connection can be increased, preventing problems such as loose connections leading to insecure rope fixation.

[0033] It should be noted that the slide rail 7 is L-shaped. This design allows the slide rail 7 to better adapt to different installation environments and space constraints. The L-shaped slide rail 7 consists of two mutually perpendicular rails, forming a right-angle structure, which provides more stable support and fixation. The slide rails 7 are arranged in pairs, that is, two sets of L-shaped slide rails 7 are set on the side wall of the outer shell 6 of the sensor body 1, both installed on the side wall of the outer shell 6, forming a symmetrical structure, which together provide connection points for the slider 8. This paired arrangement can provide more uniform support force and ensure the stability of the data acquisition instrument during installation and use. The slide rail 7 is fixed to the side wall of the outer shell 6 by welding or bolts. The slider 8 is set on the slide rail 7 and fixed in a specific position on the slide rail 7 by bolts. The paired slide rail 7 can better cooperate with the movement and fixation of the slider 8, providing more flexible installation and adjustment functions.

[0034] It should be noted that the clamping block 12 has a semi-circular or square block structure with a rubber layer on its inner side. The rubber layer has a moderate thickness and good elasticity and wear resistance. Located on the inner side of the clamping block 12, the rubber layer is in direct contact with the object being clamped. The main function of the rubber layer is to increase the friction between the clamping block 12 and the object being clamped, preventing slippage, and protecting the surface of the object being clamped to avoid damage caused by excessive clamping force. The elasticity and wear resistance of the rubber layer ensure that the clamping block 12 maintains a good clamping effect during long-term use, extending its service life.

[0035] It is worth noting that the elastic plate 13 is made of spring steel. Spring steel is an alloy steel with high strength, high elasticity, and good toughness. It can maintain a constant elastic force over a large deformation range, while also possessing good fatigue resistance and impact resistance. Because the elastic plate 13 is made of spring steel, it can provide a stable and durable clamping force, ensuring that the clamping mechanism 10 maintains a good clamping effect during long-term use. The high elasticity and fatigue resistance of spring steel enable the elastic plate 13 to maintain its elastic characteristics during repeated clamping and releasing, making it less prone to permanent deformation or failure.

[0036] It should be noted that the guide post 18 has a cylindrical structure and can be made of metal or non-metal. The surface of the guide post 18 is smooth and has a certain degree of wear resistance and corrosion resistance. The guide post 18 is installed on the housing 6 and connected to the housing 6 by welding, bolting, or bonding, and is used to guide the pull rope.

[0037] It is worth noting that the connecting post 15 is a boss-type structure, formed by connecting two cylinders of different diameters. Specifically, one end of the connecting post 15 has a larger diameter, and the other end has a smaller diameter, forming a stepped structure. This design makes the connecting post 15 more stable and reliable during connection and fixation. The guide post 18 is a cylindrical structure, with its inner diameter falling between the two diameters of the connecting post 15. Specifically, the inner diameter of the guide post 18 is larger than the smaller diameter end of the connecting post 15, but smaller than the larger diameter end. This design allows the guide post 18 to fit tightly onto the connecting post 15, forming a stable connection structure. The guide post 18 is mounted on the outer casing 6, and by its inner diameter engaging with the smaller diameter end of the connecting post 15, it fixes the connecting post 15 to the outer casing 6. The outer surface of the guide post 18 fits tightly against the inner surface of the outer casing 6, ensuring the stability and sealing of the connection.
