Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to an automatic meter reading and settlement device for photovoltaic power generation. Background Technology

[0002] With the rapid development of the photovoltaic power generation industry, the demand for accurate collection and efficient settlement of photovoltaic system operation data is increasing. However, the photovoltaic power generation data recording and settlement equipment currently on the market still has many technical pain points, making it difficult to meet the diverse needs of practical applications. The specific problems are as follows: Traditional photovoltaic power generation data acquisition boxes lack an effective and orderly internal wiring structure. The wires are often simply piled up or tied together. During equipment operation, they are prone to displacement, loosening, or even tangling due to vibration. This not only causes signal transmission interference and increases data acquisition errors, but may also lead to equipment failure due to poor wire contact.

[0003] Therefore, it is necessary to propose automatic meter reading and settlement equipment for photovoltaic power generation to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic meter reading and settlement device for photovoltaic power generation, so as to solve the problem that the internal wiring arrangement of traditional photovoltaic power generation data acquisition boxes lacks an effective and orderly structure, and the wiring is often directly piled up or simply tied. During the operation of the equipment, it is prone to displacement and loosening due to vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic power generation automatic meter reading and settlement device, including a data acquisition box and a photovoltaic inverter. A hollow connecting arm is fixedly rotated on the top of the data acquisition box. One end of the hollow connecting arm is fixedly connected to the photovoltaic power station bracket. A sensing component is fixed inside the data acquisition box. The output end of the photovoltaic inverter is connected to the sensing component through a wire, and the wire passes through the hollow connecting arm. A fixed frame is provided above the sensing component. Multiple isolation blocks are slidably installed inside the fixed frame along the length direction. Arc-shaped clamps for holding wires are provided on both sides of each isolation block. The wire passes between two adjacent isolation blocks.

[0006] Preferably, both sides of the data acquisition box are fixedly connected to sliding rails, and the two ends of the fixed frame are slidably installed between the two sliding rails.

[0007] Preferably, a fan is fixed inside the data acquisition box, and the air outlet of the fan is oriented towards the sensing component; An air vent is provided at one end of the fixed frame, and the air outlet of the fan is connected to the air vent through a pipe. A through hole for airflow is provided in the middle of the isolation block. Preferably, a display screen is fixedly connected to one side of the data acquisition box, a door is hinged to the other side of the data acquisition box, and auxiliary handles are fixedly connected to both sides of the data acquisition box.

[0008] Preferably, the sensing components include a current sensor, a voltage sensor, and a power sensor.

[0009] Preferably, one end of the hollow connecting arm is fixed with a fixing plate, and the four corners of the fixing plate are fixedly connected to the photovoltaic power station bracket by fixing bolts.

[0010] The technical effects and advantages of this utility model are as follows: 1. The cooperation between the sliding groove inside the fixed frame and the isolation block allows the isolation block to be flexibly adjusted along the sliding groove. The distance between adjacent isolation blocks can be flexibly adjusted according to the number and diameter of the wires. The arc-shaped clamp can clamp and fix the wires to prevent the wires from shaking and causing the connection to loosen. At the same time, it can prevent adjacent lines from getting tangled, ensuring the vertical downward distribution of the wires and the stability of the connection of the sensing components.

[0011] 2. The auxiliary handle of this utility model not only facilitates equipment handling, but also serves as a leverage point for rotation. In conjunction with the damping shaft of the hollow connecting arm, the angle of the data acquisition box can be easily adjusted. This facilitates the infrared reading unit to be aligned with photovoltaic meters at different locations, enabling multi-location meter data reading, and also meets the needs of staff of different heights and viewing angles to view the display screen, thus improving the adaptability of the equipment in diverse operating scenarios.

[0012] 3. The fan, flexible pipe, fixed frame air vents and isolation block through holes form a complete heat dissipation airflow channel. After the airflow is output from the fan, it is accurately delivered to the fixed frame through the pipe, and then evenly diffused to various areas of the wires and sensing components through the isolation block through holes, achieving the heat dissipation effect of "directional delivery + full coverage". This avoids the problem of local heat dissipation dead zones that exist in traditional heat dissipation methods, ensures that the wires and sensing components are at a suitable operating temperature, and further ensures the long-term stable operation of the equipment.

[0018] This utility model provides, for example Figure 1 - Figure 4 The photovoltaic power generation automatic meter reading and settlement equipment shown includes a data acquisition box 1 and a photovoltaic inverter. A hollow connecting arm 2 is fixedly rotated at the top of the data acquisition box 1. One end of the hollow connecting arm 2 is fixedly connected to the photovoltaic power station bracket. A sensing component is fixed inside the data acquisition box 1. The output end of the photovoltaic inverter is connected to the sensing component through a wire, and the wire passes through the hollow connecting arm 2. The sensing component includes a current sensor, a voltage sensor, and a power sensor. Each sensor adopts a high-precision industrial-grade sensor. Its signal input end is electrically connected to the output end of the photovoltaic inverter through a wire. It can collect the current, voltage, and power data during the operation of the photovoltaic system in real time, providing accurate raw data for power generation calculation and electricity bill settlement.

[0019] like Figure 1 As shown, the hollow connecting arm 2 is made of aluminum alloy, and its hollow internal structure is used to accommodate the wires and prevent the wires from being exposed and damaged.

[0020] A damping pivot is provided at the connection between the hollow connecting arm 2 and the data acquisition box 1, which can achieve 360° rotation adjustment. This facilitates adjusting the orientation of the data acquisition box 1 according to the position of the photovoltaic inverter, improving installation adaptability. One end of the hollow connecting arm 2 is fixed with a fixing plate 3. The four corners of the fixing plate 3 are fixedly connected to the photovoltaic power station bracket by fixing bolts. The fixing plate 3 is tightly fixed to the photovoltaic power station bracket by fixing bolts, ensuring that the data acquisition box 1 is installed stably and preventing the equipment from shifting due to external forces such as wind.

[0021] It should be noted that a meter data reading module and a data buffer unit are also provided. The meter data reading module is fixed on one side of the data acquisition box 1 and includes an infrared reading unit and an RS485 communication interface. The infrared reading unit can be aimed at the display screen of the photovoltaic meter and read the cumulative power generation data of the meter through infrared recognition technology. The RS485 communication interface is connected to the communication terminal of the smart meter through a signal line to realize wired reading of meter data. The data caching unit is located inside the data acquisition box 1 and is connected to the sensor components and the meter data reading module via circuitry. It uses an 8GB SD card as storage media to temporarily store the collected raw data and prevent data loss. The data collected by the data acquisition unit is transmitted to the data processing and settlement unit via a wireless transmission module. This wireless transmission module includes a 4G / 5G communication unit and a WiFi communication unit. The 4G / 5G communication unit uses a SIM card slot to install an IoT card, enabling remote data transmission. The WiFi communication unit is used for short-range wireless connection with the data processing and settlement unit. The data processing and settlement mechanism uses an industrial-grade computer host, which contains core components such as a motherboard, CPU, memory, and hard drive. The motherboard integrates a data interface for connecting to the data transmission mechanism and for processing the collected data.

[0022] like Figure 2 As shown, a fixed frame 9 is provided above the sensing component. Multiple isolation blocks 12 are slidably installed inside the fixed frame 9 along the length direction. Arc-shaped clamps for holding wires are opened on both sides of the isolation block 12. The wires pass through the space between two adjacent isolation blocks 12. Sliding grooves 11 are opened on both sides inside the fixed frame 9. The two ends of the isolation block 12 slide between the two sliding grooves 11.

[0023] The data acquisition box 1 has sliding rails 8 fixedly connected to both sides inside, and the fixed frame 9 is slidably installed between the two sliding rails 8 at both ends.

[0024] like Figure 2 As shown, a fan 7 is fixed inside the data acquisition box 1, and the air outlet of the fan 7 is set towards the sensing component. The air outlet of the fan 7 is set towards the sensing component, so that it can directly blow air to the sensing component to dissipate heat and avoid the sensing component from degrading due to high temperature operation.

[0025] like Figure 3 As shown, an air vent 10 is provided at one end of the fixed frame 9, and the air outlet of the fan 7 is connected to the air vent 10 through a pipe. A through hole 13 for airflow is provided in the middle of the isolation block 12.

[0026] The airflow generated by the fan 7 can be delivered to the inside of the fixed frame 9 through the pipe. The isolation block 12 is made of high temperature resistant insulating material. The distance between adjacent isolation blocks 12 can be flexibly adjusted according to the number and diameter of the wires. The arc-shaped clamp can clamp and fix the wires to prevent the wires from shaking and causing the connection to loosen. At the same time, it can prevent adjacent lines from getting tangled, ensuring the vertical downward distribution of the wires and the stability of the connection of the sensing components. like Figure 4As shown, the isolation block 12 has a through hole 13 in the middle for air to pass through. The through hole 13 runs through the length of the isolation block 12. The airflow delivered by the fan 7 to the fixed frame 9 can be evenly blown to each wire and sensing component through the through hole 13 to achieve all-round heat dissipation and improve heat dissipation efficiency.

[0027] like Figure 1 As shown, a display screen 4 is fixedly connected to one side of the data acquisition box 1, and a door 6 is hinged to the other side of the data acquisition box 1. Auxiliary handles 5 are fixedly connected to both sides of the data acquisition box 1. The display screen 4 is a high-definition touch screen, which can display the current, voltage, power data and cumulative power generation data collected by the sensing components in real time, making it convenient for staff to check the equipment operation status on site. At the same time, it supports setting parameters such as acquisition frequency and data storage period through touch operation.

[0028] During equipment installation and maintenance, staff can move the data acquisition box 1 using the auxiliary handle 5, which improves the ease of operation and prevents the equipment from falling and being damaged due to hand slippage. At the same time, the auxiliary handle 5 allows the data acquisition box 1 to be rotated, making it easier to read the cumulative power generation data of the meters at different locations through infrared recognition technology, which is convenient for adjustment. It also makes it easier for personnel at different angles to observe the display screen 4.

[0029] like Figure 1 , 2 As shown, a hinge is provided at the hinge joint between the door 6 and the data acquisition box 1, and a snap-lock is provided at the free end of the door 6. When opening, the door 6 can be opened simply by pressing the lock, without the need to remove the bolts, which facilitates quick inspection and maintenance of the internal components of the data acquisition box 1 and reduces maintenance difficulty.

[0030] Working principle: The hollow connecting arm 2 is fixed to the photovoltaic power station bracket by fixing plate 3 and fixing bolts. Rotate the hollow connecting arm 2 at the top of the data acquisition box 1 (using the damping shaft) to adjust the position of the data acquisition box 1 to align with the photovoltaic inverter, ensuring convenient wire connection. Open the box door 6, pass the wires of the photovoltaic inverter output end through the hollow connecting arm 2 and the wire inlet of the data acquisition box 1, and extend them into the fixing frame 9. Slide the isolation block 12 and use the arc-shaped clamp to hold and fix the wires, completing the wire arrangement.

[0031] The sensing components (current sensor, voltage sensor, and power sensor) collect the current, voltage, and power data output by the photovoltaic inverter in real time through wires. The collected data is transmitted to the display screen 4 for real-time display, and is also temporarily stored in the internal storage module of the device to provide data support for subsequent settlement.

[0032] When fan 7 starts, the airflow generated is delivered to the air outlet 10 of fixed frame 9 through the pipe. The airflow entering fixed frame 9 is diffused through the through hole 13 of isolation block 12, and at the same time, it blows air to cool the wires and sensing components to prevent the components from overheating and being damaged, and to ensure stable operation of the equipment.

[0033] When equipment needs to be repaired, the staff can hold the auxiliary handle 5 to move the equipment (if it needs to be moved), press the buckle lock of the box door 6 to open the box door 6, slide the fixed frame 9 along the sliding track 8, and adjust its position to repair components such as the sensor components and fan 7. The operation is convenient and efficient.
