CLAIMS OF PRIORITY

This patent application claims priority from the Provisional Patent Application No. 3043/CHE/2012 filed on 25 Jul. 2012.

FIELD OF TECHNOLOGY

This disclosure relates generally to technical fields of weather protection of events in large open space involving mechanism and computer, and in one embodiment to a device to collect flash rain water by means of rapidly deployed rain collection strips driven by cables on supporting arm and tower, suitably adjusted to get profile of surface cover best suited for managing wind.

SUMMARY

A device, system, and method to protect from flash rains by covering large open area by rapid deployment of rain collection strips forming collecting surface, and prevent disruption of events and game is disclosed. In one aspect, the said device addresses the problem of sudden change in weather affecting pre planned events and games. The device enables proper utilization of stadium infrastructure especially when used by corporate executives and others who need assurance of playing condition not disrupted by rain and also need partial shading thereby allowing full utilization of stadiums when not having tournaments. People are tolerating flash rain problem as evidently seen in newspaper reports replete with games stopped and cancelled due to flash rain. An expensive full all weather stadiums is not cost effective as is evident from the low presence of such structures as present in current prior art.

In another aspect, the prior art has roof structures covering entire stadium with types that revolve to open and close which is expensive to build and the natural effect of open space is obstructed and diminished, more over the beauty of open space is obstructed by the structures meant to hold the roof The present invention maintains the beautiful natural effect. Also present in prior art, retractable cable suspended roof for stadium as per U.S. Pat. No. 4,802,314 patent, this has problem of wind management due to large surface area. Retractable cover arranged circularly like in a umbrella as per U.S. Pat. No. 6,003,269 patent, has wind problem at height and yet to become popular. Helium filled balloon based inflatable roof as per U.S. Pat. No. 4,257,199 has wind problem at height. Prior art has devices wherein people have thought of artificial cloud seeding of game cities to dissipate potential rain clouds but this is not accurate and very expensive and high power consuming and difficult to protect target area. Prior art quoted by preliminary search authority under PCT being general state of art, are U.S. Pat. No. 4,280,306 A, FR 2891856 with film converging to central point leads to difficulty in folding and does not address wind pressure build up on being single layer and WO 8904896 relates to support structures does not address the wind problem and need for rapid deployment. The present invention over comes the problems in the prior art quoted by search authorities. The present invention is low on infrastructure cost and low on power consumption compared to prior art while still giving the required protection in most economical manner. More importantly it address the need to manage wind by means of best profile of surface for air flow and wind control cable by balancing forces through drives controlled by computer. Present device for which protection is sought and the method of solving problems involved is completely different from prior art with importance to profile generation suitable for wind flow, with rapid cable connection and cable laying and cable movement on top of players without disrupting or stopping game, wind control cable managed by computer, mobility of device for required critical place and critical time, cassette like box for storing collector strips and cables thereby allowing portability.

The rapid deployment and getting right surface contour pattern configuration allowing free flow of wind enabling wind management for the large required area is the major step in working of the device. The use of aerodynamic control of wind with split arrangement of rain collection strips is the most essential ingredient for rapid deployment and retraction and for the proper working of the device. The balancing of wind pressure one by means of rotation of supporting towers for changing the angle of surface to suit wind direction and one by applying balancing force by changing the angle of wind control cables and changing applied force for the same. The presence of drainage collector allows contour surface required but still ability to collect and drain water, with drain unit being of rubber material which is essential for safety, and using water filled rubber bags for counter weight, along with safety cable to hold the unit. Set of rotating cantilever arm with tower fixed on spectator gallery suspend a supporting arm using which smaller rain collection strips are suspended to cover area near borders and curved areas where required. A rotating cantilever arm with suspended gripping tool is used to correct any problems and attaching any improperly connected wind control cable.

The plurality of camera capture profile of rain collector surface as upper layer has contrasting color and pattern compared to lower layer which helps detection of wind direction and effect and to enable proper profile by lowering one support arm and raising another support arm and by rotating the towers on the rail where needed which is predicted by the help of operator who sees image on monitor screen and moves cursor pointer from his experience and taking into account changes in wind direction as it occurs.

The scope of the Invention extends to protecting rain sensitive crops at critical periods such as flowering and fruit formation, open grain storage at harvest time, timber yard, and other open spaces. History is replete with cancelled matches, stopped games and postponed concerts and musical events and lost elections for political parties due to inclement weather. In addition when device is used for partial shading people with sun allergy will benefit from the device and women avoiding sun to protect their fair white complexion can participate in sports.

The device, systems, and methods disclosed herein may be implemented in any means for achieving various aspects, and may be executed in a form of a machine-readable medium embodying a set of instructions that, when executed by a machine, cause the machine to perform any of the operations disclosed herein. Other features will be apparent from the accompanying drawings and from the detailed description that follows.
