The utility model is described in further detail below with reference to the attached drawings and embodiments:
fig. 1 is a schematic block diagram of an internal pressure control device of an inflatable radome of the present utility model.
Detailed Description
Embodiment as shown in fig. 1, the inflatable radome internal pressure control device of the utility model comprises an inflator pump 1, a power supply control box 2 and a controller 3, wherein the power supply control box 2 is provided with an AC/DC power supply module 21, a voltage reduction module 22, a relay 23 and a load socket 24, the AC/DC power supply module 21 is connected with the mains supply and is connected with the load socket 24 through the relay 23 after passing through the voltage reduction module 22, the power supply input end of the inflator pump 1 is connected with the load socket 24, the controller 3 comprises a high-pressure ventilation valve 31 and a low-pressure ventilation valve 32, the high-pressure ventilation valve 31 and the low-pressure ventilation valve 32 respectively monitor the internal pressure difference and the external pressure difference of the radome, and the output signal of the controller 3 is transmitted to the power supply control box 2 and controls the on-off of the relay 23.
Preferably, the monitoring port of the low pressure vent valve 32 is connected to the exterior of the radome via a vent hose 33.
Preferably, the panel of the controller 3 is provided with an antenna housing internal and external pressure difference display window 34 and a parameter setting window 35. The display window on the controller panel can observe the working state of the equipment and display the internal pressure and the external atmospheric pressure of the inflatable radome; the parameter setting window can set the internal and external pressure difference control triggering conditions, and differential control of various types of radomes is realized.
When the device works, the power plug of the air pump is inserted into the load socket on the power control box, the air inflation interface of the air pump is connected with the inflatable antenna housing, the AC/DC power module is connected with the mains supply (220V), and the output signal of the controller is connected to the relay.

When the inflatable antenna cover is required to be inflated, the controller outputs a signal to the relay, and the relay is electrically controlled to the load socket to be connected with a power supply, so that the inflator pump is started to inflate the inflatable antenna cover. When the controller monitors that the pressure difference between the internal pressure of the inflatable antenna housing and the external atmospheric pressure reaches a set value, the relay is controlled to lose electricity through the output signal, so that the power supply of the load socket is disconnected, and then the inflator pump is closed to stop inflation.
The device can automatically open and close the inflator pump according to the internal and external pressure difference of the inflatable radome, thereby controlling the internal pressure of the inflatable radome, solving the problem that the inflatable radome collapses due to too small internal air pressure and the internal pressure explodes too much, and achieving the effects of unattended operation and intelligent control.
