Description
Technical field
The utility model belongs to wireless telecommunications, particularly a kind of intellectual water meter well lid antenna.
Background technology
Along with the progress of technology; intellectual water meter replaces traditional manual metering to be used in huge numbers of families; some intellectual water meters need to be carried out real time communication, transmission water-meter data message and be received the instruction that control end is assigned water meter by antenna and gateway control end; but when some are arranged on the intellectual water meter of metal well lid; if the bad abnormal problem of intellectual water meter work that often there will be of grounding, for popularization and the use of intellectual water meter have brought difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of intellectual water meter well lid antenna, ensures that by the grounding disc arranging antenna both can be arranged on nonmetal manhole cover and carry out work and simultaneously also can ensure to cover normal work in metal well.
To achieve these goals, the technical solution of the utility model is: a kind of intellectual water meter well lid antenna, comprise antenna upper cover, lower cover and be provided with antenna core between antenna upper cover and lower cover, screw thread support tube is arranged under antenna and covers, antenna lead-out wire is drawn from screw thread support tube, wherein, described antenna core includes the metal grounding disc that a diameter is at least 160mm, be provided with lead-out wire connecting hole at the center of metal grounding disc, at metal grounding disc surface insulation, antenna switching pcb board is installed, on pcb board, be welded with antenna oscillator, antenna oscillator is apart from least 8mm of metal grounding disc.
Scheme is further: the distance between described antenna oscillator and metal grounding disc is fixed by nylon double-screw bolt and nylon screw.
Scheme is further: described antenna oscillator is placed in the central authorities of metal grounding disc.
Scheme is further: described antenna oscillator is that thickness is 0.2 foreign copper-nickel alloy sheet, be shaped as rectangle, be provided with wide 1.5mm at the minor face of rectangle, at least 10mm rectangular of length, the described rectangular frequency regulator as antenna, adjusts its length and can do appropriate amount of fine-tuning to working band.
The beneficial effects of the utility model are: simple in structure.
A. the grounding disc design of original creation ensures that antenna both can be arranged on nonmetal manhole cover and carry out work and also can ensure to cover normal work in metal well simultaneously.
