Description

Technical Field

[0001] This invention relates to the field of gateway technology, and in particular to a multi-type device protocol compatibility conversion device for microgrid operation and management systems. Background Technology

[0002] The multi-protocol compatibility conversion device for microgrid operation and management system is essentially a microgrid multi-protocol communication gateway, also known as a protocol conversion gateway or heterogeneous communication adapter. It is a core hardware and software integrated device that breaks down communication barriers between different devices and management systems in a microgrid. In essence, it is a communication hub at the edge layer, solving the problems of heterogeneous device protocols, data incompatibility, and difficulty in unified control within a microgrid.

[0003] Microgrids, as the core carrier for distributed energy grid connection and consumption, are widely used in industrial parks, remote mountainous areas, islands, and other scenarios. Among them, the multi-type equipment protocol compatibility conversion device is the communication core of the microgrid, undertaking the functions of protocol parsing, data conversion, and command forwarding for heterogeneous devices such as photovoltaic inverters, energy storage converters, charging piles, and smart meters. It is the foundation for realizing intelligent scheduling and operation and maintenance of microgrids.

[0004] As microgrids evolve towards unattended operation, outdoor multi-protocol gateways face numerous technical challenges, including:

[0005] Existing outdoor multi-protocol gateways only have communication conversion functions and do not integrate a visual monitoring module. In remote and unattended scenarios, the devices are at risk of theft and damage, and cannot detect anomalies around the devices in real time, making fault tracing difficult.

[0006] Although some gateways are equipped with solar power modules, the photovoltaic panels are mostly fixed installations without automatic storage functions. In dusty weather or when not in use at night, the surface of the photovoltaic panels is prone to accumulating dust and debris.

[0007] Cleaning photovoltaic panels relies on manual inspections, which is costly and time-consuming for microgrids in remote areas. If cameras are installed at a fixed angle, the monitoring range is limited and cannot achieve full coverage of the area around the equipment, making it difficult to meet comprehensive operation and maintenance needs. Summary of the Invention

[0008] To address the aforementioned problems, the present invention aims to propose a multi-type equipment protocol compatibility conversion device for microgrid operation and management systems, thereby resolving issues such as insufficient security protection capabilities, inadequate power supply energy efficiency, and insufficient protection.

[0009] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a multi-type equipment protocol compatibility conversion device for a microgrid operation and management system, including a multi-protocol gateway, mounting brackets installed on both sides of the multi-protocol gateway, a monitoring probe located below one end of the multi-protocol gateway, an adjustment component on the multi-protocol gateway for adjusting the up, down, left, and right positions of the monitoring probe, an energy-saving component that supplies power to the monitoring probe and has a dustproof function at one end of the multi-protocol gateway, and a cleaning component on the multi-protocol gateway for cleaning the energy-saving component.

[0010] A further improvement is made in that: the adjustment component includes a U-shaped frame, which is installed below one end of the multi-protocol gateway. A rotating shaft is rotatably installed between the upper and lower ends of the U-shaped frame. The bottom of the rotating shaft is connected to the output end of the adjustment motor. The adjustment motor is installed at the bottom of the U-shaped frame. A rotating rod is installed in the middle of the outer side wall of the rotating shaft. The monitoring probe is movably positioned at one end of the rotating rod.

[0011] A further improvement is made in that: a groove is provided at one end of the rotating rod, and a second rotating shaft is rotatably installed between the two sides of the groove. An adjustment motor is installed at one end of the second rotating shaft, and the second adjustment motor is installed on one side of the rotating rod. A rotating block is installed in the middle of the outer side wall of the second rotating shaft, and the rotating block and the monitoring probe are fixedly installed.

[0012] A further improvement is made in that: the energy-saving component includes a solar photovoltaic panel, the energy-saving component is disposed at one end of a multi-protocol gateway, and connecting plates are installed on both sides of one end of the multi-protocol gateway. A horizontal groove is formed on the connecting plate, and a lead screw is rotatably installed in one of the horizontal grooves. A threaded block is provided on the outer side wall of the lead screw. A connecting shaft is fixedly installed on both sides of the solar photovoltaic panel, and one connecting shaft and threaded block are rotatably installed. A rack is fixedly installed below one side of the horizontal groove, and a gear that meshes with the rack is installed on the outer side wall of the connecting shaft. One end of the lead screw is connected to the output end of a servo motor. An installation groove is formed on the horizontal groove, and the servo motor is installed in the installation groove.

[0013] A further improvement is that a guide rod is fixedly installed in another of the transverse grooves, and a slider is slidably installed on the outer side wall of the guide rod. The slider and another connecting shaft are rotatably installed.

[0014] A further improvement is that the cleaning component includes a long shaft, which is rotatably mounted on a mounting bracket, and a brush plate is detachably mounted on one end of the long shaft.

[0015] A further improvement is made in that: a connecting rod is rotatably mounted on one end of the multi-protocol gateway via a bracket, a short shaft is rotatably mounted on one end of the multi-protocol gateway, bevel gear one is mounted on both sides of the connecting rod, and bevel gear two is mounted on one end of the short shaft and the top of the rotating shaft one. The two bevel gear two mesh with the two bevel gear one respectively. A large synchronous pulley and a small synchronous pulley are mounted on the outer wall of the short shaft and the outer wall of the long shaft respectively. The large synchronous pulley and the small synchronous pulley are driven by a synchronous belt.

[0016] A further improvement is that: a through hole is provided at the top of the brush plate, the long shaft passes through the through hole, an external thread is provided on the outer side wall of one end of the long shaft, and two nuts are rotatably installed on the long shaft through the external thread, with the two nuts located at both ends of the brush plate respectively.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The adjustment component is controlled by dual motors to enable the monitoring probe to swing 90° up, down, left, and right. It can identify theft, intrusion, equipment abnormalities, etc. in real time, reducing security risks in unattended scenarios. The monitoring probe is linked with the gateway communication module, which can automatically capture on-site images when the equipment data is abnormal, providing a visual basis for fault tracing and greatly shortening the operation and maintenance troubleshooting time.

[0019] 2. When there is sunlight, the photovoltaic panel automatically extends and faces outward to power the monitoring probe and the gateway backup system, reducing dependence on mains power. In rain, snow, sandstorms, or at night, the photovoltaic panel automatically moves back. During the movement, it automatically reverses 180 degrees through the transmission of gears and racks, so that the front faces outward and is stored in the gateway housing, where it is sealed with the rubber plate to achieve dust and water protection and extend the service life of the photovoltaic panel.

[0020] 3. During operation, the cleaning and adjustment components of the photovoltaic panel are mechanically linked. Using the power of the rotating monitoring probe, the brush plate is driven to automatically wipe the surface of the photovoltaic panel through the transmission of bevel gears and synchronous wheels. There is no need to configure a separate cleaning motor, saving hardware costs and energy consumption. Attached Figure Description

[0029] To deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. The multi-type equipment protocol compatible conversion device of the microgrid operation management system in this embodiment is suitable for outdoor scenarios such as unattended microgrids in remote mountainous areas, independent microgrids on islands, and distributed microgrids in industrial parks. Its core is to realize the integrated functions of communication conversion, intelligent monitoring, energy-saving power supply, and automatic cleaning through the integrated design of regulating components, energy-saving components, cleaning components and multi-protocol gateways. In this embodiment, regulating motor 1 403 and regulating motor 2 407 are selected as 42BYGH34 type two-phase hybrid stepper motors to adapt to the light load precise control requirements of the monitoring probe swing; the servo motor is selected as 60ST-M01330 type permanent magnet synchronous servo motor to meet the power output requirements of solar photovoltaic panel extension and rotation; the monitoring probe 3 is selected as a high-definition network camera with infrared night vision function, the solar photovoltaic panel 501 is selected as a 10W flexible photovoltaic panel, and the brush plate 602 is selected as an anti-static brush plate.

[0030] according to Figures 1-7As shown, the multi-protocol compatibility conversion device for the microgrid operation and management system provided in this embodiment includes a multi-protocol gateway 1. Mounting brackets 2 are installed on both sides of the multi-protocol gateway 1, allowing the device to be wall-mounted to an outdoor communication cabinet or wall. A monitoring probe 3 is located at the bottom of one end of the multi-protocol gateway 1. An adjustment component 4 is provided on the multi-protocol gateway 1 to adjust the up, down, left, and right positions of the monitoring probe 3. An energy-saving component 5, which supplies power to the monitoring probe 3 and has a dustproof function, is also provided at one end of the multi-protocol gateway 1. A cleaning component 6 is provided on the multi-protocol gateway 1 to clean the energy-saving component 5. The multi-protocol gateway 1 integrates a battery, a protocol conversion module, and a wireless communication module. The battery stores the electrical energy converted by the solar photovoltaic panel 501, providing power to the monitoring probe 3 and the gateway's backup system.

[0031] The adjustment assembly 4 includes a U-shaped frame 401, which is welded and fixed to one end of the multi-protocol gateway 1. A rotating shaft 402 is rotatably mounted between the upper and lower ends of the U-shaped frame 401 via bearings. The bottom of the rotating shaft 402 passes through the U-shaped frame 401 and is connected to the output end of the adjustment motor 403 via a coupling. The adjustment motor 403 is bolted to the bottom of the U-shaped frame 401. A rotating rod 404 is welded and fixed to the middle of the outer side wall of the rotating shaft 402. The monitoring probe 3 is movably mounted at one end of the rotating rod 404. A groove 405 is provided at one end of the rotating rod 404. A rotating shaft 406 is rotatably mounted between the two sides of the groove 405 via bearings. One end of the rotating shaft 406 passes through the side wall of the rotating rod 404 and is connected to the output end of the adjustment motor 407. The adjustment motor 407 is bolted to one side of the rotating rod 404. A rotating block 408 is welded and fixed to the middle of the outer side wall of the rotating shaft 406. The rotating block 408 and the monitoring probe 3 are fixedly mounted with bolts. During actual monitoring, adjusting motor 403 drives shaft 402 to rotate in both directions, which in turn drives rotating rod 404 to swing 90° left and right in the horizontal direction. Adjusting motor 407 drives shaft 406 to rotate in both directions, which in turn drives rotating block 408 to swing 90° up and down in the vertical direction, thereby increasing the monitoring range. The monitoring data is uploaded to the microgrid operation and management platform through the gateway wireless communication module. When the platform detects abnormal equipment data, it can remotely issue commands to control monitoring probe 3 to turn to the target area and capture on-site images for fault tracing.

[0032] The energy-saving component 5 includes a solar photovoltaic panel 501. The energy-saving component 5 is disposed at one end of the multi-protocol gateway 1. Connecting plates 502 are welded and fixed to both sides of one end of the multi-protocol gateway 1. A transverse groove 503 is formed on the connecting plate 502. A lead screw 504 is rotatably mounted in one of the transverse grooves 503 via a bearing. A threaded block 505 is threaded onto the outer wall of the lead screw 504. Connecting shafts 506 are welded and fixed to both sides of the solar photovoltaic panel 501. One connecting shaft 506 and the threaded block 505 are rotatably mounted via a bearing. A rack 509 is welded and fixed to one side of the groove 503. A gear 510 that meshes with the rack 509 is welded and fixed to the outer wall of the connecting shaft 506. One end of the lead screw 504 is connected to the output end of the servo motor through a coupling. An installation groove is opened on the transverse groove 503, and the servo motor is installed in the installation groove by bolts. A guide rod 507 is welded and fixed in another transverse groove 503. A slider 508 is slidably installed on the outer wall of the guide rod 507. The slider 508 and another connecting shaft 506 are rotatably installed through bearings.

[0033] In this embodiment, the multi-protocol gateway 1 is equipped with a light sensor and a rain sensor for automatically controlling the extension and retraction of the solar photovoltaic panel 501.

[0034] When there is sufficient sunlight: the light sensor detects a light intensity ≥5000 lux, the servo motor starts and drives the lead screw 504 to rotate forward, driving the lead block 505 to slide outward along the transverse groove 503. The lead block 505 drives the solar photovoltaic panel 501 to move outward synchronously. When the gear 510 on the connecting shaft 506 meshes with the rack 509, the solar photovoltaic panel 501 rotates 180° synchronously during the movement, so that the front of the photovoltaic panel faces the sun, maximizing the reception of sunlight and converting solar energy into electrical energy, which is stored in the internal battery of the gateway.

[0035] In rain, snow, or at night: When the rain sensor detects rainfall or the light sensor detects light intensity <1000 lux, the servo motor reverses and drives the lead screw 504 to reverse, driving the lead block 505 to slide inward along the transverse groove 503. The gear 510 meshes with the rack 509, causing the solar photovoltaic panel 501 to rotate 180° in the opposite direction, so that the front of the photovoltaic panel faces the end face of the multi-protocol gateway 1. When the photovoltaic panel is fully retracted, its front face is tightly attached to the rubber plate on the end face of the multi-protocol gateway 1, achieving dustproof, waterproof, and snowproof protection, and extending the service life of the photovoltaic panel.

[0036] The cleaning component 6 includes a long shaft 601, which is rotatably mounted on a mounting bracket 2 via bearings. A brush plate 602 is detachably mounted on one end of the long shaft 601. A connecting rod 603 is rotatably mounted on a bracket below one end of the multi-protocol gateway 1. A short shaft 604 is rotatably mounted on one end of the multi-protocol gateway 1 via bearings. Bevel gears 605 are welded to both sides of the connecting rod 603. Bevel gears 606 are welded to one end of the short shaft 604 and the top of the rotating shaft 402. The two bevel gears 606 mesh with the two bevel gears 605 respectively. A large synchronous pulley 607 and a small synchronous pulley 608 are welded and fixed to the outer wall of the outer side and the outer wall of the long shaft 601, respectively. The large synchronous pulley 607 and the small synchronous pulley 608 are driven by a synchronous belt 609. A through hole is opened at the top of the brush plate 602, and the long shaft 601 passes through the through hole. An external thread 610 is opened on the outer wall of one end of the long shaft 601. Two nuts 611 are rotatably installed on the long shaft 601 through the external thread 610. The two nuts 611 are located at both ends of the brush plate 602. The brush plate 602 can be fixed on the long shaft 601 by tightening the nuts 611. The brush plate can be replaced by loosening the nuts when disassembling. When the solar photovoltaic panel 501 is in the extended power generation state and needs cleaning, the regulating motor 403 drives the rotating shaft 402 to rotate 90°. The rotating shaft 402 drives the connecting rod 603 to rotate through the meshing of the bevel gear 606 and bevel gear 605 at the top. The bevel gear 605 at the other end of the connecting rod 603 meshes with the bevel gear 606 on the short shaft 604, thereby driving the short shaft 604 to rotate. The short shaft 604 drives the long shaft 601 to rotate 180° through the transmission of the large synchronous pulley 607, the synchronous belt 609, and the small synchronous pulley 608. The long shaft 601 drives the brush plate 602 to rotate synchronously. The brush of the brush plate 602 contacts and wipes the surface of the solar photovoltaic panel 501 to remove dust, fallen leaves, and other debris from the surface of the photovoltaic panel, ensuring power generation efficiency. After cleaning, the regulating motor 403 rotates in the opposite direction, driving the brush plate 602 to reset and not block the photovoltaic panel from sunlight.

[0037] In actual use, the device in this embodiment can remotely control the operation of each component through the microgrid operation and management platform, or it can be automatically controlled through the controller inside the gateway, without the need for manual operation, which greatly reduces the operation and maintenance cost of outdoor microgrids. The integrated design of each component with the multi-protocol gateway is compact, easy to install, and suitable for various microgrid scenarios without mains power or in remote areas.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
