The invention provides a variable torque wave energy hydraulic power generation device, which consists of a plurality of pieces of equipment such as a pile body, a wave energy power generator room, a plurality of groups of crank rocker devices, a plurality of groups of floater moment arms, a plurality of groups of oscillating floaters, a generator room pushrod, a wireless communication device and a wave instrument. The wave instrument can be used for measuring the real-time wave height and tide level data of waves, and driving the floater moment arms and the generator room pushrod to be elongated or shortened according to preset rules, thereby changing the lengths of the floater moment arms and the floating position of the wave energy power generator room and actively adjusting the magnitude of wave energy input torque. The device can be used for obtaining more stable wave energy, and a wave energy collection device and an offshore wind energy collection device are fused into a whole to collect both the wave energy of the oscillating floaters and offshore wind energy for power generation, so that the utilization efficiency of energy resources is favorably improved, and the power generation cost is lowered.

Oceanic tidal energy sources hydroelectric generating system coupled to a primary tidal reservoir through a bi-directional tideway exciting a primary turbine as a diurnal cycle tide waxes and wanes. A secondary tidal reservoir includes a tideway and secondary turbine with flow modulated by a gradated control of a sluice gate to proportionately blend reserve tidewater capacity of the secondary tidal reservoir as a delayed resource of virtual tidal influx and reflux. An aggregate summation of tidal energy acting upon the turbine driven generators delivers a constant flow of electric power throughout the diurnal tidal cycle. A tertiary tidal reservoir operating in alternation with the secondary tidal reservoir optimizes the secondary turbine drive during slack-tide. Shunting excess tidal energy around the turbines during periods of reduced power-demand supplements tidal resources in subsequent phases of the diurnal tidal day when solar-day related power-demand may increase.

The invention provides a variable moment type wave energy hydraulic power generation device, which consists of a pile body, a wave energy generator cabin, multiple sets of crank rocker devices, multiple sets of float force arms, multiple sets of oscillating floats, engine room push rods, wireless communication device, tide meter and other equipment. Use the tide meter to measure the real-time data of wave height and tide level, and drive the multiple groups of buoy arms and engine room push rods to extend or shorten according to predetermined rules, thereby changing the length of the multiple groups of buoy arms and changing the The floating position of the wave energy generator cabin actively adjusts the size of the wave energy input torque. Utilizing the device of the present invention can obtain more stable wave energy, integrate the wave energy collection device and the offshore wind energy collection device into a whole, not only can collect the wave energy of multiple oscillating buoys to generate electricity, but also collect offshore wind energy to generate electricity at the same time, which is beneficial Improve energy utilization efficiency and reduce power generation costs.

The invention discloses a method and device for achieving unidirectional flow of a beheaded river through tide. A cutoff wall is arranged in the center of the beheaded river with the river width beingB. The initial end of the cutoff wall is B / 2 away from the beheaded river head, and the terminal end of the cutoff wall is located at the intersection of the beheaded river and a main tidal waterway.Check gats are arranged between the two sides of the terminal end of the cutoff wall and the beheaded river bank correspondingly, one of the check gates is a water inlet check gate which is opened during tide rising for controlling water flow of the main tidal waterway to flow into the beheaded river unidirectionally, and the other check gate is a water outlet check gate which is opened during tide falling for controlling water flow of the beheaded river to flow into the main tidal waterway unidirectionally. Through the cutoff wall and the two check gates, tide water power can be used, rising-falling repeated flow of the beheaded river is changed into unidirectional circular flow, refreshed water amount is proportional to the tidal range and the beheaded river water area, the water flow effect is good, the refreshed water amount is high, the water level of the beheaded water is controllable, the method and device are easy and convenient to implement, project investment is reduced, theconstruction period is short, the operation and maintenance is low, and the method and device have the application and popularization prospects.

A two-lane ship lock having center-wall tanks that hold water drained from one lane for use in filling the second lane as the unit is operated. The method reduces transit water-use where a lock connects a waterway to a sea with large daily tides by capturing seawater in a lagoon at high tide for use at start of chamber refilling during lower tides.

The invention discloses a marine floating ball wireless positioning signal transmitting device for marine resources, and relates to the technical field of ocean resources. According to the marine floating ball wireless positioning signal transmitting device for marine resources, a floating box is fixedly installed on the outer wall of the front side of a marine floating ball body, and a connecting base is fixedly installed at the bottom of the marine floating ball body. According to the invention, the buoyancy of the marine floating ball body is effectively and obviously increased, so that a weight increasing anchor and a metal chain can extend to the deep position of the seabed, the offset influence of waves, wind directions and water flow on the marine floating ball body is reduced, the situation that the chain is wound and knotted can be avoided, a signal collection transmitter can be well fixed, the situation that the signal collection transmitter is damaged due to collision on the sea surface is avoided, the contacted sea surface garbage can be buffered, and the influence of the acting force generated during contact on the ocean floating ball body is relieved.

A system for capturing and containing waterborne floating debris in bays, harbors, rivers, and other waterways with current, tidal, or wind action flow. This system utilizes a hinged capture gate attached to any of the commercially produced oil slick containment boom systems along with an anchoring deployment that orients the debris trap perpendicular to current, prevailing wind, and tidal flow in employed waterways. The door frame / door gate invention along with the alignment and anchoring of the boom material will allow floating debris to be captured and held within the boom material for later collection and disposal or recycle. This system allows mandated oil slick boom to serve the extended purpose of collecting floating debris before it enters the open oceans and inland waterways. Thousands of yards of oil slick boom are in place that could be utilized to catch and contain waterborne trash and valuable recyclables in every coastal bay, harbor, and waterway worldwide. Removal of floating debris from the debris trap is accomplished with a small boat or skiff and a dip net. This trash may be collected for disposal by municipal agencies that both recycle, remove and (or) compost land borne waste.
