Description
Technical field
The invention belongs to fluid machinery and thermal measurement control technology field.Aerostatics (floating air balls, dirigible) the ground device for expelling ice and snow that relates to a kind of open-air mooring is specifically related to be applicable to the spherome surface ice-snow clearing device of large-scale aerostatics such as position formula captive balloon.
Background technology
Aerostatics such as captive balloon are in the winter time or when the ground mooring of weather cold district is safeguarded, burs such as frost, accumulated snow, icing adhere to spherome surface, constituted the huge hidden danger that threatens the aerostatics safe operation: can increase spheroid weight on the one hand, the aerostatics and the ground obstacle that are docked on the mooring gear of ground are collided and the damage spheroid; Can destroy the aerodynamic configuration of aerostatics on the other hand, cause the spheroid flight resistance to increase, flight stability descends.For the soft aerostatics of this class of captive balloon, the comparatively actv. ground deicing method of present known employing mainly contains five kinds: 1) Mechanical Method, by mobile before and after the snow scraping plate on the fixing spheroid is on the ball surface, remove the accumulated snow on the balloon surface smoothly; 2) chemical method is by spraying deicing solution except ice machine, dissolving spherome surface accumulated snow; 3) heat energy method is utilized except ice machine jets of heated air or hot water removing spherome surface ice and snow; 4) pneumatic process, the high velocity air of using heater unit blows down spheroid ice and snow; 5) pressure vibration method changes the spheroid internal pressure repeatedly and produces the spheroid vibration, and spheroid accumulated snow is removed.Since the device for expelling ice and snow of the method for snow melt deicing operation or employing to a great extent by accumulated snow and ice sheet form characteristic and physical-mechanical properties determines, usually after the snowfall soon without the fresh snow of spreading, quality is soft, and methods such as available high velocity air, snow scraping plate or pressure vibration are removed; And snowfall is by the ice and snow compound of freezing formation, and quality is harder, is difficult to remove with methods such as snow scraping plate, pressure vibrations; Change into for accumulated snow and to freeze the ice sheet that forms behind the water again, dewater exceptionally, also has a small amount of silt particle, quality is hard, mechanical means is removed more difficult, must use specific process such as chemical solution, heating power deicing to clear up this moment, and snow scraping plate, high pressure draft etc. can't guarantee elimination efficiency at all during simultaneously for the accumulated snow on the on-plane surfaces such as balloon afterbody and empennage.Therefore, adopt someway separately, all can't guarantee to remove fully the ice and snow of aerostatics spherome surface.
Summary of the invention
In order to solve the difficult problem that existing deicing measure can't be removed soft aerostatics spherome surface accumulated snow fully, the present invention is directed to the special usage condition of aerostatics and avenged the big characteristics of area, a kind of pipeline fountain device for expelling ice and snow has been proposed.
The technical solution that realizes above-mentioned deicing purpose is as follows:
The pipeline fountain device for expelling ice and snow that is used for aerostatics comprises ground heating device, supercharging equipment, transmission and distribution network and spray appliance.Described transmission and distribution network and spray appliance comprise tower shape bracing frame 2, are provided with transfusion hard tube 4 along the short transverse of tower shape bracing frame 2; The upper end of transfusion hard tube 4 is being communicated with the house steward's 5 that infuses a end, and transfusion house steward's 5 the other end is being communicated with two afterbody transfusion arms by three-way pipe; The uniform liquid supply electromagnetic valve 3 of connecting on transfusion house steward 5 and described two afterbodys transfusion arm, the delivery port of liquid supply electromagnetic valve 3 is provided with nozzle bar 15, and the upper end of nozzle bar 15 is provided with movable shower nozzle 6; The other end parallel connection of described two afterbodys transfusion arm, the parallel connected end of two afterbody transfusion arms is provided with water escape valve 8.
