The first side plate 20 and the second side plate 30 are both detachably fixedly connected to the shell 10 through a fixing nut 60;The two surfaces of the housing 10 adjacent to the side plate are provided with heat sinks 40, wherein the heat sinks 40 are embedded in the two sides of the housing 10, and two symmetrically arranged guide plates 402 are arranged inwardly on the heat sink 40, and a limiting plate 403 is arranged on the guide plate 402.

A connecting rod cavity 405 and a sealing cavity 408 are also provided in the guide plate 402, wherein the connecting rod cavity 405 is connected to the notch, a connecting rod 404 is slidably arranged inside the connecting rod cavity 405, and a sealing block 407 is slidably arranged inside the sealing cavity 408, and the sealing block 407 is fixed together with the connecting rod 404 by a connecting shaft 406. The sealing cavity 408 is divided into a closed space by the sealing block 407. The space is filled with one of paraffin and grease. The melting point of paraffin is between 40-60°C. After the paraffin melts, it expands in the closed space of the sealing cavity 408, which allows the passage sealing block 407 to move. When it solidifies, it shrinks, thereby driving the sealing block 407 to retract. A main limit block 4031 is fixed on the limit plate 403. The main limit block 4031 can limit the two limit plates 403 to each other, and the installation is completed. The end faces of both sides of the guide plate 402 are provided with heat sensing grooves 4 022, the heat sensing groove 4022 is located at the sealed cavity 408, and a plurality of heat conducting ribs 4023 are arranged on the inner wall of the heat sensing groove 4022, and the heat conducting ribs 4023 are evenly distributed. The heat sensing groove 4022 can be opened to transfer heat to the sealed cavity 408 stably and with less loss, and the contact area between the heat conducting ribs 4023 and the hot air can be increased by setting the heat conducting ribs 4023, so that the speed of heat dissipation and heat absorption from the air can be accelerated to a certain extent. A secondary limit block 4021 is also arranged at the bottom of the guide plate 402 to limit the maximum distance that the guide plate 402 is pushed out. ;

[0022] The shell 10 of the acquisition terminal is made of high-strength aluminum alloy material with good corrosion resistance and heat dissipation performance. The surface of the shell 10 is sandblasted and anodized to enhance its wear resistance and aesthetics. The internal layout of the shell 10 is reasonable, and there is enough space between the modules for heat dissipation and maintenance. At the same time, the shell 10 is also designed with a waterproof and dustproof sealing structure to ensure stable operation even in harsh outdoor environments; the processor module has a built-in intelligent algorithm that can pre-process the monitoring data, detect anomalies and provide fault warnings; the processor module is the core of the acquisition terminal and uses a high-performance embedded processor, such as the ARMCortex-A series, equipped with sufficient RAM and Flash storage space. The processor is responsible for receiving the raw data from each monitoring unit and performing tasks such as data pre-processing, analysis, storage and transmission. In order to achieve efficient data processing, the processor is integrated with a DSP (digital signal processor unit) specifically for signal processing and data analysis.

[0023] Furthermore, in one embodiment of the present invention, a solar panel 101 is provided on the upper end of the housing 10; the solar panel 101 can directly utilize solar radiation energy to convert into electrical energy, providing a stable and reliable energy supply for the collection terminal. This means that in remote areas where the power supply of the power grid is unstable or cannot be accessed, the collection terminal can still work normally, which enhances its adaptability and reliability; solar energy is a clean and renewable energy source, and using solar panels 101 to supply power can significantly reduce dependence on and consumption of traditional energy, reduce carbon emissions, and help protect the environment and promote sustainable development; the solar panel 101 can be modularly designed to facilitate installation and removal on the housing 10 of the collection terminal. At the same time, since the solar panel 101 usually has high reliability and stability, its maintenance cost is relatively low.

[0024] Furthermore, in one embodiment of the present invention, a reinforcing rib 102 is provided on the other side of the housing 10 adjacent to the side plate, a plurality of heat dissipation holes 401 are provided on the heat dissipation plate 40, and a handle is provided on the heat dissipation plate 40. When the handle is pulled outward, the sealing block 407 cannot move due to the enclosed space in the sealing cavity 408. At this time, the pulling force acts on the two main limit blocks 4031, and the two main limit blocks 4031 are set as arc surfaces. When the handle is pulled hard, the two main limit blocks 4031 can be separated from the mutually locked state, thereby achieving the purpose of removing the heat dissipation plate 40; the reinforcing rib 102 is a supporting structure inside the housing 10, which can significantly improve the overall rigidity and strength of the housing 10. When subjected to external pressure or impact, the reinforcing rib 102 can effectively disperse stress, prevent the housing 10 from deformation or rupture, and thus protect the safety of the internal electronic components; the heat dissipation hole 401 is an important channel for heat dissipation on the housing 10. When the acquisition terminal works for a long time, the internal electronic components will generate a lot of heat. The heat dissipation holes 401 can discharge the heat to the outside of the housing 10 in time, reduce the internal temperature, and prevent the components from being damaged or performance degradation due to overheating; the design scheme combining the reinforcing ribs 102 with the heat dissipation holes 401 not only enhances the structural strength and stability of the housing 10, but also improves the heat dissipation performance of the equipment. This design scheme makes the substation dedicated transformer collection terminal more relaxed in dealing with complex and changeable outdoor working environments, and can provide accurate monitoring data in a long-term and stable manner, providing strong support for the construction and operation of smart grids.

[0025] Furthermore, in one embodiment of the present invention, a bracket 70 is provided at the bottom of the shell 10, and the bracket 70 is fixedly connected to the shell 10 by a fastening screw 701; the bracket 70, as the contact point between the shell 10 and the ground or other installation surface, can provide a stable support to prevent the acquisition terminal from shifting or tipping over due to vibration, shaking or external force during operation. This is crucial to ensure the stable operation and extend the service life of the acquisition terminal; the design of the bracket 70 can also reduce the vibration impact of the external environment on the acquisition terminal to a certain extent, protect the internal electronic components from damage, and improve the reliability of the equipment; the bracket 70 is fixedly connected to the shell 10 by a fastening screw 701, and this design allows the acquisition terminal to adjust the installation position and angle according to actual needs during installation to adapt to different installation environments and requirements; when the acquisition terminal needs to be maintained or repaired, the acquisition terminal can be easily removed from the installation position by removing the fastening screw 701, which is convenient for subsequent operations.

[0026] An auxiliary heat dissipation group 50 is also arranged in the guide plate 402. The auxiliary heat dissipation group 50 includes a main rack 501, a secondary rack 503 and a connecting shaft 504. Both racks slide in the guide plate 402. The main rack 501 and the secondary rack 503 are meshed with each other through the gear 502. The gear 502 rotates in the guide plate 402. One end of the connecting shaft 504 is fixed in the secondary rack 503, and a fan 508 is installed at the other end through a bearing. The fan is located in the heat dissipation plate 40, and its blades are arranged at an angle to ensure that when the device is installed outdoors, the fan rotates to bring the airflow into the device during the process of the airflow passing through the fan. The two fans are tilted in opposite directions. When the airflow blows the fans in the same side direction, one fan can be used for blowing and the other for sucking, so that the air inside the device can circulate quickly with the outside world and perform conversion, further enhancing the heat dissipation effect of the device. Moreover, when the airflow blows from the front of the heat sink, air convection can be directly performed through the heat sinks on both sides for rapid ventilation. One end of the main rack 501 is connected to the limit plate 403, and a guide hole 506 is provided in the guide plate 402, which also passes through the heat sink 40. The connecting shaft 504 is located in the guide hole 506, and a filter plate 507 is fixed on the inner wall of the guide hole 506 located at the heat sink 40, which can be used for filtering External dust and other debris, the connecting shaft 504 passes through the filter plate 507 and is slidably connected thereto, and connecting holes 505 are provided on both side end faces of the guide plate 402, and the connecting holes 505 are arranged at the middle of the guide hole 506. When air flows, the airflow will flow in from the connecting holes 505, and the unfiltered dust carried by the airflow will continue to move under the action of inertia and remain in the guide hole 506, effectively preventing a large amount of dust from entering the device. The connecting hole 505 is connected to the guide hole 506. When the temperature inside the device is high, the two heat dissipation plates 40 are opened outwards, and at this time the limit plate 403 and the guide plate 402 produce relative movement, that is, driving the main rack 501 The gear 502 drives the auxiliary rack 503 to slide, thereby driving the connecting shaft 504 to move to the side away from the limit plate 403. At this time, the fan 508 can be extended out of the heat sink 40. If there is air flow outdoors at this time, the fan 508 can be driven to rotate. The rotation of the fan 508 will accelerate the flow of air in the device. In order to prevent external dust and debris from entering the device, only a small gap will be generated when the heat sink 40 is opened. At this time, the fan 508 accelerates the air flow in the device, which can further accelerate the conversion of the air in the device, thereby ensuring that the amount of dust entering is reduced while further improving the heat dissipation effect of the device.

[0027] Furthermore, in one embodiment of the present invention, a remote upgrade interface supporting online upgrades of firmware and algorithms is also included; the acquisition terminal has a built-in large-capacity Flash storage chip for storing historical data and firmware programs. Historical data can be uploaded to a remote monitoring center or exported to a local storage device as needed. To facilitate subsequent functional expansion and maintenance, the acquisition terminal is also designed with a remote upgrade interface that supports receiving firmware update packages sent by a remote server via a wireless network to achieve online upgrades of the device.

[0028] The shell 10 also includes a data acquisition module, a data processing module, a communication module, a power management module, at least one new energy power generation monitoring unit 201, at least one distribution transformer monitoring unit 202 and a display unit; the new energy power generation monitoring unit 201 mainly includes monitoring sensors for photovoltaic power generation and wind power generation. For photovoltaic power generation, a high-precision current and voltage sensor is used, which is installed at the output end of the photovoltaic panel to monitor the output current and voltage of the photovoltaic panel in real time, and then calculate the amount of electricity generated. At the same time, the inverter status monitoring module is used to obtain the operating efficiency, fault information, etc. of the inverter. For wind power generation, additional monitoring sensors for environmental parameters such as wind speed, wind direction, and temperature may be required.

[0029] The data acquisition module is connected to the new energy power generation equipment and the distribution transformer respectively, and is used to collect the operating data of the two in real time; The data processing module processes and analyzes the collected data according to the preset algorithm and generates a monitoring report; the data processing module has a built-in new energy generation characteristic identification algorithm and a distribution transformer health assessment model, which can automatically identify the type of new energy generation and evaluate the distribution transformer operation status to achieve accurate monitoring and early warning; Working principle: After the acquisition terminal is started, it first performs self-check and initialization operations to confirm that each module is connected normally and is in standby state. Subsequently, it starts to collect the status data of new energy power generation equipment and distribution transformers on a regular or on-demand basis. The processor module preprocesses and analyzes the collected data to determine whether there is an abnormality or fault. If an abnormality or fault is found, the early warning mechanism is immediately triggered, and the alarm information and detailed data are reported to the remote monitoring center through the communication module. At the same time, the corresponding alarm information is displayed on the display unit to prompt the operation and maintenance personnel to deal with it in time. The operation and maintenance personnel can view historical data, alarm records or modify equipment parameters as needed. Finally, when a remote upgrade command is received, the acquisition terminal will automatically download and install the update package to complete the online upgrade of the firmware program. This area-specific transformer acquisition terminal that supports monitoring of new energy and distribution transformers highly integrates the monitoring functions of new energy power generation and distribution transformers, and realizes efficient management of multiple links of the power system through carefully designed hardware architecture and software algorithms. The new energy generation monitoring unit 201 accurately captures the working status of photovoltaic panels, wind power equipment, etc., and provides data support for optimizing the grid connection of new energy; the distribution transformer monitoring unit 202 comprehensively monitors the health status of distribution transformers, prevents potential failures, and ensures the stable operation of the power grid; each sensor module is connected to the processor module through wired or wireless means, and the processor module calculates and identifies the health status of the distribution transformer through algorithm analysis. Once an abnormality is found, the early warning mechanism is immediately triggered, and the alarm information and detailed data are reported to the remote monitoring center through the communication module. At the same time, the display unit of the terminal provides users with intuitive on-site information display, which is convenient for operation and maintenance personnel to quickly locate problems.

[0030] After the terminal has gone through the above series of operations, each electronic component and module inside it will generate a large amount of heat. When it is running at low power, the heat dissipation effect can be achieved directly through the heat dissipation holes 401 on the heat dissipation plate 40. However, when it is running at high power, the heat dissipation holes 401 cannot dissipate heat in time, and the heat will accumulate in the shell 10. When the accumulated heat reaches a certain temperature, it will be conducted to the inside of the sealed cavity 408 through the heat conductive ribs 4023 in the heat sensing groove 4022, so that the paraffin inside the sealed cavity 408 melts. The volume of the paraffin melted into liquid will increase, which can push the sealing block 407 to move to the side away from the heat dissipation plate 40. The limiting plate 403 is driven to abut against the guide plate 402 on the other side through the connecting shaft 406 and the connecting rod 404. The thrust generated by the sealed cavities 408 on both sides can make the guide plates 402 on both sides move relative to each other, so that the heat dissipation plates 408 on both sides are 0 is separated from the shell 10, and its internal space is opened, so that its internal space is directly in contact with the outside world, so as to achieve the effect of rapid cooling. After the temperature drops, the paraffin in the sealed chamber 408 gradually solidifies from a melted state to a solid due to insufficient temperature. The volume of the paraffin will shrink when it solidifies. Since the inside of the sealed chamber 408 is in a closed state, the sealing block 407 moves toward one side of the heat sink 40 under the action of atmospheric pressure, thereby driving the limit plate 403 to move synchronously through the connecting rod 404 and the connecting shaft 406. However, since the two main limit blocks 4031 limit each other, the two limit plates 403 will not move, and the two guide plates 402 will move inward synchronously, thereby driving the two heat sinks 40 to gradually move toward the side close to the shell 10, and re-seal the inside of the shell 10. At this time, the problem of rapid heat dissipation under high-power operation can be solved, and the whole terminal automatically completes the opening and closing operations.

[0031] In summary, the acquisition terminal supporting monitoring of new energy and distribution transformers can achieve installation effect by setting the guide plate 402 and the limit plate 403, on the one hand, mutually limit each other through the main limit block 4031 on the limit plate 403, and on the other hand, can sense the temperature inside the current shell 10 through the state of paraffin to automatically and quickly dissipate heat, so as to avoid excessive accumulation of heat inside the shell 10 and affect the normal use of electronic components inside the shell 10; through the setting of the heat dissipation hole 401, when the terminal is used in a normal state, the heat generated by these electronic components can be discharged to the outside of the shell 10 in time, so as to reduce the internal temperature and prevent the components from being damaged by overheating or performance degradation; by highly integrating the monitoring functions of new energy power generation and the monitoring functions of distribution transformers, the intelligent management level of new energy power generation equipment and distribution transformers is improved, and the operation and maintenance cost is reduced; the real-time monitoring and early warning mechanism effectively prevents the occurrence of faults and improves the reliability and safety of power grid operation; data-driven decision support provides a scientific basis for the optimal dispatching of the power system; the modular design facilitates maintenance and upgrading, and enhances the scalability and adaptability of the equipment; by integrating solar panels into the shell, the self-sufficient energy supply of the acquisition terminal is realized. This not only reduces dependence on traditional power grids, but also reduces operating costs, while also embodying the concept of green, environmentally friendly and sustainable development.
