Fine mesh fish larvae protection system for traveling water screens
A traveling water screen comprises a basket having a frame including an upper portion, a lower portion, and side portions, a coarse screen secured to the frame, a fine screen overlay attachable to the coarse screen, and a bucket portion secured to a lower portion of the frame, comprising an inner wall surface, and at least one deflector secured to the inner wall surface.
Method and device for treating cyanobacteria in water area based on biological competition principle
The invention discloses a method and a device for treating cyanobacteria in a water area based on the principle of biological competition, the method comprising: finding an area where cyanobacteria most easily accumulate, i.e. a concave bank of a water area, and setting up an algae interception net around the area; quickly and largely clearing the cyanobacteria in the area by means of manual or mechanical catching; planting emerged plants on the shoreline of the water area to fundamentally improve water quality; and additionally, densely arranging treatment tanks in a larger water area to kill the cyanobacteria gradually, and collecting dead cyanobacteria to prevent them from polluting the water area subsequently; and collecting and treating the tanks regularly for recycling.
Precast Dam Structure With Flowpath
A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.
Water Intake Floating Row Cleaning System and Construction Method Thereof
The invention relates to a water intake floating row cleaning system, including first vertical guide rail assemblies, a floating row, submersible pumps, water spraying assemblies, second vertical guide rail assemblies, floating fences and pumping assemblies, wherein the water spraying assemblies are communicated with the submersible pumps, and the submersible pumps pump the water of the river channel and spray the water towards the outside through the water spraying assemblies; and the floating fences stretch across the water intakes and float along with a water level, and the pumping assemblies are used for pumping out garbage blocked by the floating fences. The invention has the effect of efficiently cleaning the floating garbage at the water intakes.
FENCE SYSTEM AND METHOD OF USE
A fence includes a wall panel portion having an upper edge and a lower edge, and a plurality of tubular pockets running across the wall panel between the upper edge and the lower edge. The tubular pockets each configured to receive a mounting post. The upper edge and the lower edge can each include a channel in which a draw cord is threaded. The fence can further include an apron portion extending from the lower edge of the wall panel portion. Methods of installing the fence are also provided.
Extended quarters
In some implementations, a modular furniture cabinet includes a top flooring affixed to static furniture and supported by one or more structures. The top surface of a bottom flooring, backs of the static furniture pieces, and a bottom surface of the top flooring define a storage space, and the dynamic furniture pieces substantially reside in the storage space when the modular furniture cabinet is in a closed configuration.
Precast Dam Structure With Flowpath
A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.
Floating litter trap
A floating litter collection system for collecting floating debris from the surface of water flowing in a water stream, comprising a wire mesh container having an open front end, a first buoyant device secured to a first side of the container, a second buoyant device secured to the second side of the container, and a pair of mooring lines for anchoring the container to the water banks of the water stream. The system may include a pair of floating booms secured to the mooring lines to direct debris floating on the surface of the water into the container. The system may include a fin attached to the bottom of the container to orient the front end of the container in an upstream direction. The system may include a floating anchor to orient the front end of the container in an upstream direction.
AUTOMATIC REMOVE EQUIPMENT FOR DISASTER BLOOMING MARINE ORGANISMS OF SEA WATER INTAKE CHANNEL
Automatic remove equipment for disaster blooming marine organisms of sea water intake channel belongs to the field of marine environmental engineering and equipment. The equipment comprises a cod-end of collecting net, a saw blade at the end of net, a fixation and support system, a submersible spiral pump, a transport pipe system, a separating system on coast and floats. The equipment collects the disaster blooming marine organisms in the sea water channel into the bottom of a cod-end of collecting net, and cuts and decomposes the collected disaster blooming marine organisms by using a saw blade at the end of net under the combined action of the water flow power and the suction pressure of a submersible spiral pump. Fragments after cutting are sucked by the submersible spiral pump and delivered to a coast, and are subjected to solid-liquid separation by a separating system on coast and then are centrally disposed. The equipment is sturdy and durable and can resist corrosion of the sea water environment; and the equipment can efficiently collect and remove the disaster blooming marine organisms in the industrial sea water intake channel automatically, thereby saving labor cost, ensuring normal operation of the industrial system and increasing production benefits.
Grid bar for a bar screen of a filter unit, and filter unit equipped therewith
A grid bar for a screen grid of a screen includes a multiple number of grid bars arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from a flowing liquid, such as wastewater flowing in a sewer channel. The grid bar includes a plastic reinforced with fibers, whereas at least a part of the fibers extend in a longitudinal direction of the grid bar. A screen includes such a screen grid.
