Place a TTimer on your form, set interval to 5000 ms (5 mins) and set enabled:=true


type
    TfMain = class(TForm)
    Timer1: TTimer;
    procedure TimerTimer(Sender: TObject);

  private
        
...

implementation

{$R *.dfm}

procedure TfMain.Timer1Timer(Sender: TObject);
begin
  ADOQuery1.Refresh;
  //DBGrid1.Refresh;
end;
