Description

Technical Field

[0001] This utility model relates to the field of photovoltaic intelligent power distribution and utilization remote monitoring technology, specifically a photovoltaic-based intelligent power distribution and utilization remote monitoring device. Background Technology

[0002] In recent years, global demand for clean energy has continued to grow, and photovoltaic (PV) power generation, with its clean and renewable advantages, has become increasingly important in the energy structure. With the large-scale construction of PV power generation projects, the number of PV power plants and their installed capacity have been steadily increasing. According to data from the International Energy Agency, the global compound annual growth rate of PV power generation capacity has exceeded 25% over the past decade. Not only are large-scale centralized PV power plants increasing, but distributed PV power generation is also being widely used in industrial and commercial rooftops and residential buildings. The large-scale integration of PV power generation places higher demands on the stability, security, and power quality of power distribution systems.

[0003] Traditional power distribution systems primarily rely on unidirectional power supply. However, the integration of photovoltaic (PV) power generation transforms the distribution network into a complex network with multiple power sources and nodes, resulting in more complex power flow distribution. Furthermore, smart power distribution systems in PV power plants are typically located in relatively remote areas and are large-scale, making manual inspection difficult. Remote monitoring can monitor equipment operating status in real time, promptly identify potential problems, improve system reliability and stability, ensure the normal operation of PV power plants, and reduce power outage time and power generation losses.

[0004] Currently, remote monitoring devices are typically used outdoors, with all their interfaces exposed to the elements, making them susceptible to damage from rain, dust, sand, and other natural factors. This can easily lead to internal circuitry issues such as moisture damage and short circuits, shortening their lifespan. Therefore, how to protect the interfaces of remote monitoring devices is an urgent problem to be solved. Utility Model Content

[0028] Specifically, the front panel 3 is hinged to the front end of the protective cover 2, and a door lock 4 is installed between the other side of the front panel 3 and the protective cover 2.

A sealing gasket 7 is fixed at the rear edge of the protective cover 2, and the sealing gasket 7 is in contact with the wall.

[0029] In this embodiment, the protective cover 2 and the upper edge plate 5 are an integral structure. The sealing gasket 1 6 is glued to the inside of the front panel 3, and the sealing gasket 2 7 is glued to the protective cover 2. Both the sealing gasket 1 6 and the sealing gasket 2 7 are made of rubber and are used to seal and protect the front panel 3 and the protective cover 2, as well as the protective cover 2 and the wall, to prevent rainwater or dust from entering.

[0030] Specifically, a moisture-absorbing pad 8 is provided on the bottom inner side of the protective cover 2. Multiple wiring grooves adapted to the wiring ports at the bottom of the remote monitoring device 1 are respectively opened on the bottom inner side of the protective cover 2 and the moisture-absorbing pad 8. A limiting device is installed on the wiring grooves. The clamping components include a stop block 9, a latching block 10, a push rod 12, and a mounting block 13. The stop block 9 is embedded and fixed to one side of the wiring groove on the moisture-absorbing pad 8. The latching block 10 is located above one side of the stop block 9 and is rotatably connected to the stop block 9. Limiting pads 11 are fixed inside the stop block 9 and the latching block 10, respectively. One end of the push rod 12 is rotatably mounted on the upper end of the latching block 10, and the other end is rotatably mounted on the bottom of the mounting block 13. The mounting block 13 is sleeved on the outside of the threaded rod 15 and the guide rod 14 and is threadedly connected to the threaded rod 15. 5 and guide rod 14 are installed inside the protective cover 2.

The wiring port at the bottom of the remote monitoring device 1 is connected to each connecting wire. The protective cover 2 is placed over the remote monitoring device 1, and the connecting wires are inserted into the corresponding wiring slots. The screws are screwed into the remote monitoring device 1 through the threaded holes on both sides of the protective cover 2 and then driven into the wall. The connecting rod 19 is pulled outward, the connecting spring 20 is compressed, and the locking block 21 is separated from the currently connected slot 22. The handwheel 17 is rotated, which drives the threaded rod 15 to rotate through the universal joint 16. Under the limiting guidance of the guide rod 14, the mounting block 13 moves, and the locking block 10 is rotated through the push rod 12 to clamp the connecting wires locked between the stop block 9 and the locking block 10. Then, the handwheel 17 is stopped, the connecting rod 19 is released, the connecting spring 20 is reset, and the locking block 21 is inserted into the corresponding slot 22.
