Detailed Description
The present invention will be described in further detail with reference to the following embodiments:
a wireless data transmission device for explosion-proof electrical equipment comprises a shell, wherein an antenna 1, a power supply interface 3 and an intrinsic safety signal interface 2 are arranged outside the shell; a safety grid is arranged inside the shell.
The antenna 1 is hinged to a first connecting part 12, the first connecting part 12 is rotatably connected to a second connecting part 13 through a screw device 11, and the second connecting part 13 is fixed on one side of the shell.
The power source interface 3 is fixed to the side of the housing adjacent to the second connecting portion 13.
The intrinsic safety signal interface 2 is fixed on one side of the shell opposite to the power interface 3.
The inside backup pad 6 that passes through of shell is separated for upper plenum and lower cavity, the upper plenum is equipped with communication safety bars 4 and wireless signal equipment 8, the cavity is equipped with power safety bars 5 and support column 7 down.
The intrinsically safe signal interface 2 is sequentially connected with the communication safety barrier 4, the wireless signal equipment 8 and the antenna 1, and the communication safety barrier 4 is used for converting intrinsically safe signals.
The communication safety grid 4 is arranged at one side of the inner part of the shell close to the intrinsic safety signal interface 2; the wireless signal device 8 is arranged on one side of the inside of the housing close to the second connecting part 13.
The number of the support columns 7 is two, the top of each support column is fixed to the bottom of the support plate 6, and the bottom of each support column is fixed to the bottom inside the shell.
The power interface 3 is connected with a power supply safety barrier 5 and used for supplying power to explosion-proof electrical equipment and the device, and the power supply safety barrier 5 is arranged between two support columns 7 and below the communication safety barrier 4.
And a strong magnet block 9 is arranged at the bottom of the shell.
The power supply adopts power of more than 2W, and the sensor of the explosion-proof electrical equipment and the wireless signal equipment can be ensured to operate normally at the same time.
For example, when the device is applied to a fuel dispenser, the intrinsic safety signal interface 2 of the device is connected with an RS485 cable of the fuel dispenser, the intrinsic safety signal enters the communication safety barrier 4 from the intrinsic safety signal interface 2, the communication safety barrier 4 converts the intrinsic safety signal into a non-intrinsic safety signal, the non-intrinsic safety signal is converted into a wireless signal through the wireless signal device 8, and the wireless signal is transmitted out from the antenna 1 and is received by a control room or other receivers. The device is mainly applied to data communication between the oiling machine and the explosion-proof electrical equipment and the control room in the oil tank area; the magnetic type installation mode is adopted, construction is convenient, construction cost is reduced, and the field can be completed only by simple construction power supply without stopping operation.
