The magnetic coupling heating system of the disc type oscillating water column type wave heater shown in fig. 2 adopts two groups of magnetic coupling surfaces, but adopts the matching combination of two induction disc assemblies and two magnetic block fixing disc assemblies. The magnetic coupling heating system of the disc type oscillating water column type wave heater shown in fig. 3 adopts two groups of magnetic coupling surfaces, but adopts the matching combination of two induction disc assemblies and a magnetic block fixing disc assembly. The magnetic coupling heating system of the disc type oscillating water column type heat dissipater shown in fig. 1, 2 and 3 can be used in series, i.e. more than two sets of magnetic coupling surfaces are used. In the figure, the reference number 2-1 is a high-speed shaft of the gearbox, the reference number 2-2 is a turbine, the reference number 2-3 is a contraction pipe, and the reference number 2-4 is an air chamber.

Fig. 6 shows a form of a disc type oscillating water column type heat dissipater for heating, in which a heating medium is air, and turbulent flow fans 1-3 are added to accelerate heat dissipation.

Fig. 9 is a schematic diagram of a magnetic block fixing disc assembly of a magnetic coupling heating system of a disc type oscillating water column type wave heater, wherein permanent magnets with N poles and S poles are alternately arranged, and the magnetic pole direction is parallel to the axial direction. N pole permanent magnets and S pole permanent magnets in a magnetic block fixing cylinder assembly of the magnetic coupling heating system of the cylinder type oscillating water column type wave heater are also alternately arranged, but the magnetic pole direction of the N pole permanent magnets and the S pole permanent magnets is perpendicular to the axial direction. The induction disc assembly of the magnetic coupling heating system of the oscillating water column type wave heater at least comprises an induction disc and a shielding plate in principle, and when the two parts are made of the same material, the two parts can be directly integrated, and the thickness of the plate can be properly controlled.
Fig. 10, 11 and 12 show an improved scheme of an oscillating water column type wave energy driving system, wherein an air chamber 2-4 is connected with a contraction pipe 2-3 through a pipeline, control valves are arranged at an air chamber exhaust port, an air chamber suction port, an atmosphere exhaust port and an atmosphere suction port, and a check valve is adopted in the scheme, and the valves are opened or closed in a self-adaptive manner by sensing the change of air pressure, so that air continuously flows through a turbine 2-2 to drive the turbine to rotate. Fig. 11 is a schematic diagram showing the operation of the oscillating water column type wave energy driving system when waves rise, air in an air chamber is compressed, when air pressure p1 of the air chamber is greater than air pressure p2 at the front end of a turbine, a check valve at an air outlet of the air chamber is opened, the compressed air in the air chamber flows through the turbine to do useful work, at the moment, the check valve at an air inlet of the air chamber is closed because the air pressure p3 at the rear end of the turbine is less than the air pressure p1 of the air chamber, but the air pressure p3 at the rear end of the turbine is greater than the atmospheric pressure p0, the check valve at an atmospheric outlet is opened, and the compressed air flowing through the turbine is discharged into the atmosphere. Fig. 12 is a schematic diagram showing the operation of the oscillating water column type wave energy driving system during wave descent, when the wave descends, the air in the air chamber expands, the air pressure p1 in the air chamber decreases, when the air pressure p1 in the air chamber is smaller than the air pressure p2 at the front end of the turbine, the check valve at the air outlet of the air chamber is closed, when the air pressure p3 at the rear end of the turbine is larger than the air pressure p1 in the air chamber, the check valve at the air inlet of the air chamber opens, at this time, the air pressure p3 at the rear end of the turbine and the air pressure p at the front end of the turbine are both smaller than the atmospheric pressure p0, so the check valve at the air outlet is closed, the check valve at the atmospheric inlet is opened, and the atmosphere is sucked and flows through the turbine to do useful work. Through the reasonable design runner, the gas pressure of control business turn over turbine can make the turbine operate steadily high-efficiently. The check valves in fig. 10, 11, and 12 may also be replaced with remote control valves, which perform closed-loop automatic control according to pressure data monitored by a pressure sensor in real time, and the common remote control valves may be electric, hydraulic, pneumatic, electro-hydraulic, etc., such as electric ball valves, electromagnetic valves, etc.
Fig. 13, 14, 15, 16 and 17 show a further modification of the oscillating water column wave energy drive system. The principle of the solution shown in fig. 13 is the same as that shown in fig. 10, except that the turbine 2-2 is a steam turbine (the steam turbine is a device for generating power in a power plant and is driven by high-temperature and high-pressure steam, but is driven by compressed air, so the steam turbine can be named as a steam turbine, and the working conditions of the two applications are different). Figure 14 shows a schematic diagram of a parallel arrangement using a plurality of turbines and shrink tubes 2-3. Figure 15 shows a schematic of a tandem arrangement using multiple turbines and shrink tubes 2-3. Fig. 16 is a schematic diagram of another series arrangement using multiple turbines and shrink tubes 2-3, which is a multi-effect series arrangement with stepwise changes in air pressure. Fig. 17 is a schematic diagram of another parallel scheme using multiple turbines and shrink tubes 2-3, which is a multi-effect parallel with stepwise changes in air pressure. The check valves in fig. 13, 14, 15, 16 and 17 may also be replaced by remote control valves, which perform closed-loop automatic control according to pressure data monitored by a pressure sensor in real time, and the common remote control valves are electric, hydraulic, pneumatic, electro-hydraulic, and the like, such as electric ball valves, electromagnetic valves, and the like.
Figure 18 shows a modification of the arrangement of figure 16 in which an artificial atmosphere is used instead of an open atmosphere. The artificial atmosphere is a compressed air storage tank which stores compressed air with certain pressure. The scheme shown in fig. 18 enables the working medium (as flowing air for driving the turbine) to form an independent system, so that the pressure control of the whole system is convenient, and the oscillating water column type wave heater can stably and efficiently output high power. The artificial atmosphere environment can be adopted by various structural types of the oscillating water column type heat dissipater.
Fig. 19 shows an improved scheme of the oscillating water column type wave energy driving system, wherein a guide column and a movable sealing plate are additionally arranged in an air chamber 2-4, and the movable sealing plate moves up and down along the guide column under the action of waves so as to enable the air in the air chamber to obtain necessary pressure and simultaneously reduce pressure loss caused by a cavitation effect.
Fig. 20 shows a simple modified version of the oscillating water column type wave energy drive system, in which an open atmosphere is replaced by an artificial atmosphere made of a compressed air storage tank with compressed air stored therein, the compressed air storage tank and the air chamber 2-4 are directly connected by a contraction tube 2-3, and the air directly enters the air chamber or the compressed air storage tank after passing through the turbine 2-2.
