Description

Technical Field

[0001] The utility model relates to the technical field of集线 devices, and specifically relates to a集线 device for a photovoltaic power station. Background Technique

[0002] The main function of a hub is to regenerate, reshape and amplify the received signals to expand the transmission distance of the network. At the same time, all nodes are concentrated on the nodes centered on it. It works on the first layer of the OSI reference model, that is, the "physical layer". Like network cards, network cables and other transmission media, a hub belongs to the basic equipment in a local area network and adopts the CSMA / CD medium access control mechanism. Each interface of the hub simply transmits and receives bits. When it receives 1, it forwards 1, and when it receives 0, it forwards 0, without collision detection. When multiple groups of hubs are installed, a集线 device is used for the installation of the equipment.

[0003] According to the search, the Chinese patent document, publication number: CN216489354U, discloses a集线 device for a photovoltaic power station. Through the provided ventilation slots, hollow slots, clamping plates and ventilation pipes, the ventilation slots and hollow slots are convenient for increasing the ventilation volume of the wiring board and improving the heat dissipation effect of the集线 device. Several groups of clamping plates are convenient for installing multiple groups of circuits and wires. The U-shaped ventilation box is convenient for heat dissipation treatment of the interior of the machine body, increasing the heat dissipation area of the installation components of the集线 device, thereby improving the use effect of the processing device. However, during the use process, the cables cannot be stored, which easily leads to cable scattering, not only making it troublesome for later inspection and maintenance, but also easily affecting other cables in case of cable damage. And only through the heat dissipation slots for heat dissipation, due to the concentration of cables, it is easy to cause heat accumulation, which in turn affects the service life of the cables.

Advantageously, the fixed plate 201, the buffer plate 202, and the connecting plate 203 facilitate connection of the limiting mechanism 3, thereby improving the overall stability and load-bearing capacity during use.

[0034] Specifically, the limiting mechanism 3 includes a slide 301, a guide wheel 302, and a buffer spring 303. The slide 301 is formed on opposite sides of the buffer plate 202.

[0039] When in use, the middle part of the cable is limited by the connecting column 504, so that during the winding process, the connecting rod 501 is driven to rotate by starting the winding motor, and then the winding drum 502 is driven to rotate, and then the left and right ends of the cable are wound at the same time and limited by the limiting groove 503, which is beneficial to avoid the influence of cable clutter on later maintenance, and is also beneficial to straighten the cable and avoid the phenomenon that the cable is too long and easy to be entangled. In addition, by starting the fan 403, the air inside the outer box 1 is driven to circulate through the through hole 5013 on the outside of the connecting rod 501, which is beneficial to dissipate the heat inside the outer box 1 and the heat generated by the cable during use. The amount is discharged, and at the same time, the heat on the winding drum 502 is facilitated to be conducted and dissipated through the heat dissipation fins 5012 under the action of the heat conduction plate 5011, and the overall heat dissipation efficiency is high. Subsequently, in the process of winding, the cable is guided and limited by the guide wheel 302, and at the same time, the buffer spring 303 is used to buffer and reset while squeezing, thereby helping to avoid twisting of the cable and correct it, thereby improving the cable winding stability and service life, and under the action of the fixed plate 201, the buffer plate 202 and the connecting plate 203, it is conducive to connecting the limiting mechanism 3, thereby improving the stability and load-bearing capacity during the overall use process.
