Mobile barrier to control litter and wind

Abstract

A mobile barrier for use in wind control, reduction of blowing litter and suspension and transport of airborne contaminants with applications in areas of landfill maintenance, agriculture, erosion control, and snow control is described. The mobile barrier is a large mesh panel supported in an orientation which is at a slight angle to the vertcial. The panel is supported using a pair of upright members which extend upward from a base which is freestanding. A vertically adjustable lifting boom is also supported by the upright members, and is used to secure the mobile barrier to lifting machinery for purposes of transport. Further, a system for controlling the spread of wind-borne contaminants will be described which includes a mobile barrier in combination with a misting device.

1 . A mobile barrier device for control of wind and windbome contaminants, the mobile barrier device comprising a massive freestanding base, two uprights extending generally upward from the base, a planar panel selected from the group consisting of i) expanded planar panels and ii) perforated planar panels, supported by the uprights, and an adjustable lifting means.  
   
   
       2 . The mobile barrier device of  claim 1  wherein the planar panel comprises a generally planar body having a panel front face, a panel rear face, and a thickness which is small relative to its width and length, the planar panel supported by a rigid frame, the rigid frame comprising peripheral support members which form a frame about the periphery of the, the rigid frame comprising cross support members which extend between peripheral support members to reinforce the planar panel.  
   
   
       3 . The mobile barrier device of  claim 2  wherein each of the two uprights comprise an elongate tube of square cross section, the elongate tube having an upper end and a lower end, the lower end being opposed to the upper end and separated from it by the body of the elongate tube, the lower end being rigidly secured to the base such that the elongate tube is oriented at an angle which is 10 degrees from the vertical.  
   
   
       4 . The mobile barrier device of  claim 3  wherein the elongate tube has an upright front face, an upright back face which is opposed to the upright front face, and upright lateral side faces which separate and extend between the upright front face and the upright back face, wherein the planar panel is secured to each respective upright so that the panel front face is positioned so as to confront the upright back face of each respective upright and so that the plane in which the planar panel resides is oriented at an angle which is 10 degrees from the vertical.  
   
   
       5 . The mobile barrier device of  claim 4  wherein the adjustable lifting means comprises an elongate horizontally oriented lifting tube, the lifting tube comprising a first end which is adjustably secured to one of the two uprights, the lifting tube comprising a second end which is opposed to the first end and which is adjustably secured to the second of the two uprights, the lifting tube comprising means to releasably secure the mobile barrier to lifting and transporting machinery.

       15 . A mobile barrier device for control of wind and windborne contaminants, the mobile barrier device comprising a massive freestanding base, two uprights extending generally upward from the base, a planar panel supported by the uprights, 
 wherein the base comprises a main longitudinal tube, a first transverse foot tube, and a second transverse foot tube,    the main longitudinal tube lying generally in parallel with a bottom edge of the planar panel,    the first transverse foot tube positions at a first end of the main longitudinal tube and oriented perpendicularly to the main longitudinal tube,    the second transverse foot tube positions at a second end of the main longitudinal tube and oriented perpendicularly to the main longitudinal tube, and    the main longitudinal tube, the first transverse foot tube, and the second transverse foot tube all lying in a single plane,    wherein the planar panel comprises a generally rigid planar body having a panel front face, a panel rear face, and a thickness which is small relative to its width and length, the planar panel supported by a rigid frame, the rigid frame comprising peripheral support members which form a frame about the periphery of the, planar panel, the rigid frame comprising cross support members which extend between peripheral support members to reinforce the planar panel,    wherein each of the two uprights comprises an elongate tube of square cross section, the elongate tube having an upper end and a lower end, the lower end being opposed to the upper end and separated from it by the body of the elongate tube, the lower end being rigidly secured to the base such that the elongate tube is oriented at an angle which is 10 degrees from the vertical.    
   
   
       16 . The mobile barrier device for control of wind of  claim 15  wherein the mobile carrier device comprises an adjustable lifting means for lifting and transporting the mobile barrier device. 
 the adjustable lifting means comprises an elongate horizontally oriented lifting tube, the lifting tube comprising a first end which is adjustably secured to one of the two uprights, the lifting tube comprising a second end which is opposed to the first end and which is adjustably secured to the second of the two uprights, the lifting tube comprising means to releasably secure the mobile barrier to lifting and transporting machinery.
