Constriction and pull-out of corroded trunnion pin sleeves, paired with pedestal jack support to stabilize tainter gates during drilling and replacement.

Frictionally holding the contact plate in an insulating frame simplifies ceramic heater assembly, cuts part handling, and lowers manufacturing cost.

An AI-controlled diversion pipe switches between flood bypass and natural river flow to protect vulnerable areas without drying the riverbed.

Adjustable pipe diversion redirects floodwater while preserving river flow at low levels, reducing basin costs and avoiding riverbed drying.

Hydrodynamic modeling and PID feedback coordinate parallel canal gates to improve water distribution, power generation, and control accuracy.

A gravity-fed inflatable weir keeps the tailrace outlet submerged during power failure, preventing turbine cavitation and air ingress.

A dual-pulley cable drive moves gate motors above the flood line, protecting electronics while enabling larger gates in deeper channels.

A bypassing gate edge forms a shear point at the threshold to cut plant material, enabling full channel closure and sealing.

Semi-helical flow bodies turn culvert runoff into rotational flow to raise drainage capacity, flush debris, and preserve fish passage.

An integrated gate channel uses contact-triggered valve control to deliver accurate ecological flow with less dam construction.

A hinged flap and fan-shaped pulley use water pressure for tight sealing while opening smoothly and clearing sand or slurry at discharge.

Sensors and powered gate control hold target diversion flow despite upstream level swings, reducing overdelivery, underdelivery, and flooding.

An arcuate barrier and dual-pulley cable path let a larger control gate handle deeper channels while keeping the motor and electronics above floodwater.

A bi-fold barrier and cable drum replace wear-prone gears to keep pipe flow control accurate, low-force, and reliable in harsh conditions.

An exterior rib frame and floating annular rib grid reduce casting defects, stress concentration, and deflection in fluid control slide gates.

Semi-helical flow bodies turn culvert runoff into rotational flow to raise capacity, flush debris, reduce flooding, and preserve fish passage.

A failsafe clutch decouples the centrifugal brake in normal use, then engages it on power loss to limit lowering speed without resizing the kinematic chain.

A downstream relief wall forms a relief lake that counteracts hydrostatic load on the main dam without emptying the reservoir.

A gravity-driven funnel and trigger valve flush reservoir sediment at a preset threshold, cutting water loss, energy use, and clogging.

Curved side walls and deflectors dissipate flow energy while preserving stable fish passage and reducing harmful vortices.

Rotating modular river cleaners use water flow to move waste downstream between modules while adapting to tides and keeping boat traffic open.

Collecting elements remove sand and stones near the lower deflection to prevent belt damage, seal overload, and unfiltered bypass.

A rotating gate slab and bottom transverse axis let water flush sediment during opening while maintaining reliable dam sealing when closed.

A dual-grating screen with automated rake and brush cleaning retains light solids and protects the pumping chamber in wastewater treatment.

Real-time sediment concentration and man-made flood waves align flood and sediment peaks to improve reservoir sediment discharge.

Oxygen-rich water plumes guide migratory fish toward ladders instead of turbine intakes, improving passage without large bypass pipes.

A permeable cage around the basin intake localizes sediment removal by gravity, limiting turbidity and avoiding full-basin dredging.

A cap linked to a new dam entombs contaminants around a decaying river structure, containing plumes and avoiding costly removal.

A rotating scraper and vortex-assisted downpipe clear thin debris from a conical hydro intake rack while bypassing the turbine.

Alternating bumps and hollows on a spillway crest improve flow adhesion and raise permissible discharge without water layer detachment.

Separate pool head and tail sections use dual-control gates and steep-slope fishways to stabilize flow and fish passage across water level changes.

A buoyancy-driven flap valve automates drainage control, reducing manual labor, clogging risk, and maintenance in farm water-level systems.

Segmented lamellae and a substrate ridge stabilize flow, cut turbulence, and improve small-fish passage with lower water demand.

Orthogonal gate motion shortens stroke to shrink the assembly, while a latch and soft rubber seal prevent accidental opening and leakage.

Coordinated gate opening with real-time water levels and demand prediction stabilizes flow and improves diversion accuracy in series water systems.

A prefabricated vertical geotextile barrier slows high-velocity runoff, filters sediment, and blocks underflow that causes ditch erosion.
