Description

Technical Field

[0001] The utility model relates to the technical field of communication gateways, in particular to a switchable RS485 / RS232 communication gateway. Background Art

[0002] A gateway is also called an internetwork connector or protocol converter. A gateway realizes network interconnection above the network layer and is a complex network interconnection device, which is only used for interconnection of two networks with different high-level protocols. When a communication gateway passes through an RS485 interface or an RS232 interface, corresponding connection wire sources can be correspondingly connected for use.

[0003] The existing Chinese patent CN109802887A discloses an RS485 / RS232 to LORA gateway and its working method on May 24, 2019. The RS485 / RS232 to LORA gateway includes an RS485 communication module, an RS232 communication module, a LORA communication module and an embedded controller. The RS485 communication module, the RS232 communication module and the LORA communication module are respectively connected to the embedded controller. The RS485 communication module and the RS232 communication module are respectively used to connect RS485 devices or RS232 devices. The LORA communication module is used to connect adjacent gateways or devices to build a wireless network and realize two-way communication.

[0004] However, when the above device is placed for use, heat dissipation is carried out through the holes in the side heat dissipation plate, so dust is likely to accumulate at the holes, which will affect the overall heat dissipation effect and lack a quick automatic cleaning structure for cleaning.

[0024] The beneficial effects of the present utility model are as follows:

[0025] 1. By providing an automatic cleaning mechanism structure, it is convenient for cleaning. When the output end of the lead screw motor of the automatic cleaning mechanism rotates, it drives the coupling to rotate, and then drives the internal lead screw of the lead screw body. A lead screw slider is installed on the periphery of the internal lead screw of the lead screw body.

An electric telescopic cylinder body is installed at the outer end of the lead screw slider. Thus, the lead screw slider drives the electric telescopic cylinder body to move up and down. The electric telescopic cylinder body drives the movable panel and the cleaning fins to move for cleaning. A first coupling is installed at the end of the telescopic rod of the electric telescopic cylinder body. Thus, when the electric telescopic cylinder body expands and contracts, it can drive the first coupling to move. The outer end of the first coupling is installed with a movable panel, so that the movable panel can be driven to move. A number of cleaning fins are arranged in an array at the front end of the movable panel. Thus, the cleaning fins can move. The cleaning fins are sleeved in the inner heat dissipation grooves of the heat dissipation panel. In this way, the cleaning fins first move inwards, then rise a certain distance, and then move outwards, so that the accumulated impurities can be touched off, making it convenient for cleaning.

[0026] 2. By providing a wire source buckling mechanism structure, the wire source can be buckled and used. The movable sleeve plate of the wire source buckling mechanism is connected to the gateway central processing unit through the anti-detachment baffle.

The rotating end plate is movably connected to the rotating shaft rod. Thus, the rotating end plate can rotate vertically. Then, due to the C-shaped sleeve buckle block at the upper end of the rotating end plate, the external wire source can be buckled and placed to avoid loosening and falling off.
