Abstract

The present invention comprises a sewer water gate to be located at the opening to a subsurface catch basin of a storm drain system that will exclude trash and debris from the system while still permitting a flow of water, but which will partially open to allow full access for water and entrained material when the rate of flow is sufficiently high while still obstructing the flow of heavier materials.

Claims

exact text as granted — not AI-modified
1 . A gate system to be located at the opening to a subsurface catch basin of a storm drain system, the opening having a given height and width, the gate system for blocking leaves, litter and other debris from entering the catch basin, the gate system comprising:
 (a) a gate frame sized to substantially occupy the catch basin opening, the gate frame consisting of a pair of parallel side brackets connected to a lower gate bracket and to an upper gate bracket, the upper and lower gate brackets sized to span the width of the catch basin opening, wherein;   (b) the lower gate bracket is comprised of a fixed gate to obstruct the passage of debris; and   (c) the upper gate bracket having rotatable means for receiving an upper gate, the upper gate to obstruct the passage of debris, and wherein   when a specified pressure of overflow water and debris impacts the upper gate portion, the upper gate portion will rotate to an open position, permitting water and debris to flow over the fixed lower gate and into the catch basin.   
     
     
         2 . The gate system of  claim 1  wherein the fixed lower gate is perforated to permit the flow of water into the catch basin. 
     
     
         3 . The gate system of  claim 1  wherein the rotatable upper gate is perforated to permit the flow of water into the catch basin 
     
     
         4 . The gate system of  claim 1  wherein the two parallel side brackets additionally include means for bracing the upper gate portion in a closed position. 
     
     
         5 . The gate system of  claim 4  additionally including bias means for biasing the rotatable upper gate against the bracing means. 
     
     
         6 . The gate system of  claim 5  wherein the bias means is selected number of magnets having a selected magnetic strength. 
     
     
         7 . The gate system of  claim 1  wherein the rotatable means is a hinge sized to substantially span the width of the catch basin opening. 
     
     
         8 . The gate system of  claim 1  additionally including filtration means extending from the lower gate portion into the subsurface catch basin. 
     
     
         9 . The gate system of  claim 8  wherein the filtration means is constructed of an anti-microbial material. 
     
     
         10 . A gate system to be located at the opening to a subsurface catch basin of a storm drain system, the opening having a given height and width, the gate system for blocking leaves, litter and other debris from entering the catch basin, the gate system comprising:
 (a) a gate frame sized to substantially occupy the catch basin opening, the gate frame consisting of a pair of parallel side brackets connected to a lower gate bracket and to an upper gate bracket, the upper and lower gate brackets sized to span the width of the catch basin opening, the parallel side brackets including means for bracing the upper gate portion in a closed position, wherein;   (b) the lower gate bracket is comprised of a fixed perforated gate to permit the flow of groundwater while obstructing the passage of debris; and   (c) the upper gate bracket having rotatable means for receiving an upper gate, the upper gate having perforations to permit the flow of groundwater while obstructing the passage of debris, and wherein   when a specified pressure of overflow water and debris impacts the upper gate, the upper gate will rotate to an open position, permitting water and debris to flow over the fixed lower gate and into the catch basin.   
     
     
         11 . The gate system of  claim 10  including bias means for biasing the rotatable upper gate against the bracing means. 
     
     
         12 . The gate system of  claim 11  wherein the bias means is a selected number of magnets having a selected magnetic strength. 
     
     
         13 . The gate system of  claim 10  wherein the rotatable means is a hinge sized to substantially span the width of the catch basin opening,. 
     
     
         14 . The gate system of  claim 10  wherein the rotatable means is a selected number of hinges spaced along the upper bracket. 
     
     
         15 . The gate system of  claim 10  wherein the rotatable means is spring loaded. 
     
     
         16 . The gate system of  claim 1  additionally including filtration means extending from the lower gate portion into the subsurface catch basin. 
     
     
         17 . The gate system of  claim 8  wherein the filtration means is constructed of an anti-microbial material. 
     
     
         18 . The gate system of  claim 8  wherein the filtration means is constructed of a hydrocarbon absorption material. 
     
     
         19 . A gate system to be located at the opening to a subsurface catch basin of a storm drain system, the opening having a given height and width, the gate system for blocking leaves, litter and other debris from entering the catch basin, the gate system comprising:
 (a) a gate frame sized to substantially occupy the catch basin opening, the gate frame consisting of a pair of parallel side brackets connected to a lower gate bracket and to an upper gate bracket, the upper and lower gate brackets sized to span the width of the catch basin opening, the parallel side brackets including means for bracing the upper gate portion in a closed position, wherein;   (b) the lower gate bracket comprised of a fixed perforated gate to permit the flow of groundwater while obstructing the passage of debris;   (c) the upper gate bracket having rotatable means for receiving an upper gate, the upper gate having perforations to permit the flow of groundwater while obstructing the passage of debris;   (d) the lower bracket additionally including filtration means extending from the lower gate bracket into the subsurface catch basin;   (e) the gate system including bias means for biasing the rotatable upper gate against the bracing means; and wherein   when a specified pressure of overflow water and debris impacts the upper gate, the upper gate will rotate to an open position, permitting water and debris to flow over the fixed lower gate and into the catch basin.   
     
     
         20 . The gate system of  claim 19  wherein the bias means is a selected number of magnets having a selected magnetic strength.
