Portable modular windscreen

Abstract

A windscreen system for use in water abatement systems such as that found in oil and gas drilling operations. The windscreen system comprises a plurality of independently portable and mountable ten foot wide sections that stand side by side about three feet apart. Each section comprises top and bottom mesh screens secured to a rigid frame that is held in a vertical position by support braces. Relatively narrow screens are hung between the rigid frames to form a continuous windscreen system.

1 . A windscreen system comprising:
 two or more rigid frames which can be assembled and secured to ground independently of one another, each frame being located adjacent to and spaced part from another frame, each frame having top and bottom horizontal poles extending between and connected to a pair of vertical side poles;   at least one rear support brace for each frame, the support brace having a top end affixed to the frame and a bottom end secured to the ground;   one or more mesh screens secured to each frame and extending between the vertical side poles and between the top and bottom horizontal poles; and   a narrow mesh screen extending between the vertical side poles of adjacent frames.   
   
   
       2 . The windscreen system of  claim 1  wherein each frame further comprises a middle horizontal pole extending between the vertical side poles between the top and bottom horizontal poles; and wherein the number of mesh screens secured to each frame is two and consists of a top screen and a bottom screen; the top screen extending between the vertical side poles and between the top and middle horizontal poles; the bottom screen extending between the vertical side poles and between the middle and bottom horizontal poles. 
   
   
       3 . The windscreen system of  claim 1  wherein the vertical side poles have hollow bottom sections and are slid over ground stakes driven into the ground. 
   
   
       4 . The windscreen system of  claim 1  further comprising one or more guy lines having an end attached to the vertical side poles and an opposite end attached to a second stake inserted into the ground. 
   
   
       5 . The windscreen system of  claim 1  wherein the at least one rear support brace is secured to the ground by an angle stake inserted through an opening located in the rear support brace near its bottom end and further inserted into the ground. 
   
   
       6 . The windscreen system of  claim 1  wherein the width of the narrow mesh screen is about three feet or less. 
   
   
       7 . The windscreen system of  claim 1  further comprising anchors secured to the ground near the vertical side poles and connected to the frame by cables. 
   
   
       8 . A windscreen system comprising:
 two or more rigid frames which can be assembled and secured to ground independently of one another, each frame being located adjacent to and spaced part from another frame, each frame having top and bottom horizontal poles extending between and connected to a pair of vertical side poles;   at least one rear support brace for each frame, the support brace having a top end affixed to the frame and a bottom end secured to the ground;   at least one wide mesh screen having a width equal to or greater than the width of the two or more frames and being secured to the two or more frames.   
   
   
       9 . The windscreen system of  claim 8  wherein the at least one wide mesh screen comprises a top wide mesh screen attached to the top and middle horizontal poles of the frames and a bottom wide mesh screen attached to the middle and bottom horizontal poles of the frames.
