[0029] The present application adopts the following key measures:

[0030] I. The multi-stage impeller compressor is surrounded by a multi-stage impeller turbine, and the straight conical surface cylindrical shell of the compressor is also the rotor of the turbine and the power output cylinder shaft, which is beneficial to the recovery of compression heat.

[0031] II. There is a multi-stage impeller compressor between the gas collection chamber and the turbine, which blocks the top of the gaseous refrigerant at the turbine outlet after the compression heat is recovered, and makes the evaporating pipe outside the throttle valve be in a low-pressure and low-temperature state easy to evaporate and absorb heat.

[0032] III. A heat exchange chamber is arranged between the compressor and the turbine, and the high-pressure and high-temperature refrigerant at the outlet of the straight conical surface cylindrical throat neck part releases latent heat through the radiator in the heat exchange chamber and condenses back to liquid state.

[0033] IV. The straight conical surface cylinder is not only the power output shaft of the turbine, but also the outer shell rotor of the compressor with embedded multi-stage impellers.

[0034] V.

The stator is fixed to the outside of the slender neck part, and the rotor is fixed to the inside of the compressor hub. The small turbine not only recovers part of the compression energy of the high-pressure refrigerant condensed back to liquid state, but also makes the compressor rotate faster on the basis of the rotating speed of the turbine, and has higher efficiency.

[0035] The heat pump engine is different from existing internal combustion engines, external combustion engines, steam turbines and other power machines. It does not consume any fuel, only needs water from rivers, lakes, seas and atmosphere with not too low temperature as heat source, can convert most of the internal energy of the water from rivers, lakes, seas and atmosphere absorbed by the low-boiling-point refrigerant into mechanical energy to drive the propeller and the generator, and has no "waste" heat discharged to the low-temperature heat source, thereby becoming a brand-new generator set or boat propulsion power machine.

[0036] Compared with the internal combustion engine providing mechanical energy, the electric motor provides mechanical energy, which is cleaner and more convenient. Compared with photovoltaic power generation, wind power and hydroelectric power, the application is less affected by climate, environment and geographical location, and is more stable in power supply, high efficiency and low cost. Compared with coal-fired boiler, oil(gas) boiler, nuclear reactor boiler and steam turbine generator set, the application has compact and exquisite structure, small floor area, easy installation, does not consume any fuel, provides cheap, abundant and simple electric energy. Compared with the nuclear power of the ship, the power unit of the application has compact and light structure, and does not occupy the cabin space and worry about nuclear radiation pollution, and the operation cost is low. Compared with the diesel engine and gas turbine power of the surface ship, the application has compact and light structure, which can be hoisted under the waterline of the stern, not only does not occupy the cabin space, but also does not need to carry fuel, the power cost is greatly reduced, and the endurance is comparable to nuclear power. Compared with the diesel-electric power of the submarine, the power of the application is much better. As the power of the helium airship in the airspace where the atmospheric temperature is not too low, compared with photovoltaic power generation, battery, electric motor power and gasoline engine power, the application is more stable and durable, and if it always flies in the low-altitude airspace in the middle and low latitudes, the endurance is comparable to nuclear power, and it is cheap and much safer.

The front compartment base is fixed to the front end of the main body shell. The front end cover is fixed to the front compartment base by screws. The propeller shaft sealing ring 25 is installed on the front end cover. The front propeller is fastened to the front end of the main shaft by a washer nut.

[0066] The rear compartment base is fixed to the rear end of the main body shell. The planetary gear 18 and 40 are installed on the rear compartment base. The planetary gear 18 is fixed to the rear compartment base by screws. The gear ring hub is fixed to the main shaft 35 by spline.

[0069] All the blades of the impeller and the hub or the wheel rim 9, 13, 14, 36, 37 are integrally machined. The hub or the wheel rim is fixed to the corresponding part by spline.

[0070] The power machine includes several temperature, pressure, and speed sensors, as well as an electronic control system that prevents private disassembly and relocation and self-destructs. The self-destructive explosive is installed in the front 4 of the compartment base, the hollow shell of the compressor stator, and the rear 17 of the compartment base.

[0071] In the specific implementation, the low-boiling-point refrigerant is sealed in the closed circulation flow path of "evaporator - gas collector - compressor - heat exchange chamber - turbine - centripetal folding return chamber - compressor - heat exchanger in the heat sink - high-pressure liquid turbine driving compressor - liquid collector - liquid core pipe in the center of each evaporation pipe - tail valve - evaporator", and the evaporator is immersed in the water of rivers, lakes and seas or the atmosphere with a general temperature not lower than 0℃.

[0072] The compressor compresses the gaseous refrigerant at room temperature and low pressure into a liquid state, which is cooled by the heat sink in the center of the heat exchange chamber, and then impacts the small turbine driving the compressor to release part of the pressure energy into the liquid collector, and then flows into the liquid core pipe of each evaporator in the four walls to the throttle valve, and then enters the evaporation pipe after throttling and pressure reduction, and then vaporizes, expands and pressurizes after absorbing the heat energy of the external heat source introduced by the pipe wall, and then flows into the gas collector and is pressed into the heat exchange chamber by the compressor to absorb the heat release of the condensed refrigerant in the heat sink to further increase the temperature, pressure and expansion, and then impacts the (main) turbine rotor, and absorbs the heat release of the compressor introduced through the blades and shaft at the same time, thereby obtaining more rotational kinetic energy.

[0073] The turbine rotation drives the compressor and main shaft rotation, the main shaft drives the propeller and generator, and at the same time, the planet gear drives the counter-rotating impeller of the alternately arranged compressor to reverse at double speed to enhance the compression efficiency. Most of the mechanical energy consumed by the compressor is converted into condensed heat release, a small part of which impacts the small turbine of the compressor at high speed to rotate, and at the same time, a low-pressure area is formed at the outlet of the main turbine, so that the main turbine obtains more rotational kinetic energy.

[0074] Take a 50MW / ship power unit as an example: as shown in Figure 2.

[0075] In order to enable the refrigerant to continuously absorb heat, evaporate, expand, recover condensed heat, further expand, pressurize, work, and then be compressed back to liquid state to flow back to the evaporator for circulation, thereby continuously outputting power, the refrigerant should be sealed in the closed circulation flow path, the working machine must be a multi-stage impeller turbine, the compressor and the compressor must also be multi-stage impeller, and the compressor must be placed in the center of the turbine and be completely surrounded by the straight-line conical cylindrical shell, which is used as the inner shell of the turbine and the conical cylindrical shaft, and also as the conical cylindrical shell of the compressor, so as to facilitate the recovery of condensed heat, which is the key.

[0076] The turbine housing is a cylindrical column, which is the middle section of the main housing, extending forward and backward to the front and rear nearly circular cone-shaped housing, and together with the front and rear conical fairing to form a shuttle-shaped streamline body. The evaporator pipes of the evaporator, which absorbs the internal energy of the environmental heat source, are arranged around the main body and surrounded by a protective cover shaped like a waist drum, and the inlet and outlet are equipped with grilles. The environmental heat source is sucked into the inlet grille by the front propeller, flows through the outer surface of the evaporator pipe, is cooled by heat absorption, is squeezed and accelerated by the gradually converging flow channel, and is driven by the tail propeller to be sprayed out of the outlet grille.

[0077] The outer wall of the straight-line conical cylinder in the main body is fixedly connected with the multi-stage impeller of the turbine rotor, which is alternately arranged with the stator guide vane fixedly connected to the inner wall of the main housing. The axis of the straight-line conical cylinder is provided with a main shaft penetrating through the front and back, and the neck part of the conical cylinder is fixedly connected with a conical top cylindrical sleeve.

[0078] The inner wall of the conical cylinder is fixedly connected with the multi-stage impeller of the compressor, which is alternately arranged with the multi-stage impeller of the compressor fixedly connected to the outer wall of the main shaft sleeve. The inside and outside of the bell mouth of the conical cylinder are the inlet of the compressor and the outlet of the turbine respectively. The outlet turns into the inlet, and the gaseous refrigerant is folded back 180 degrees to the return chamber or the inner volute chamber.

[0079] The neck part of the straight-line conical cylinder is tightly held by the cylindrical sleeve, leaving a gap between the front of the main shaft and the main shaft. The ring groove is the outlet of the compressor, and the many holes around the cylindrical sleeve are fixedly connected to the radiating pipes of the radiator, and the other end of each radiating pipe is open to the inlet of the small turbine of the driving compressor.

[0080] The heat exchange chamber with the radiator is axially arranged in front of the compressor and the turbine. This layout is the key two, that is, the compressor is necessary, the heat exchange chamber is necessary, and the existence of the compressor can make the gaseous refrigerant, which has been fully recovered and condensed heat, increase in temperature and pressure when it enters the heat exchange chamber, and does not cause top support to the upstream, so that the refrigerant after the regulating valve can be more smoothly evaporated at low pressure. At the same time, the refrigerant must release the latent heat in the radiator before flowing back to the evaporator.

[0081] The multi-stage driving impeller of the compressor, i.e. the rotor, is respectively sleeved in the outer wall of the front cabin separation base liquid chamber and the radiator base with bearing high-pressure dynamic sealing ring at the front and rear ends of the hub, and is driven by the small turbine driven by the high-pressure liquid flow from the radiator. The corresponding alternately arranged multi-stage guide vane is fixedly connected to the hollow stator shell on the inner wall of the main housing. The compressor is accelerated in rotation by the small turbine driven by the high-pressure liquid flow on the basis of the main turbine, and its compression efficiency is greatly improved, and the liquid flow pressure energy is partially recovered, which is the key three.

[0082] The gaseous refrigerant, which has absorbed heat from the ambient heat source, is collected in the plenum chamber ahead of the compressor inlet and is then distributed to the evenly distributed evaporator tubes on the periphery of the ring wall. At the same time, the liquid flow core tubes in the center of the evaporator tubes pass through the ring-shaped plenum chamber and are connected to the annular liquid collection chamber at the outlet of the small turbine in the inner wall of the center.

[0083] The front compartment base separates the front generator chamber from the main shaft and the plenum chamber. The main shaft passes through the sealing ring in the center, is then fixed by the anti-backout pin ring, and enters the front generator chamber to fix the generator rotor after being constrained by the bearing. Continue to move forward through the center sealing chamber of the circular cone-shaped main body shell to fix the front propeller. The hub is a smaller circular cone, together with the pointed cone-shaped fairing in the center of the inlet guard, forming the front section of the pointed cone-shaped streamline body.

[0084] The front support on the periphery of the main body shell at the front compartment base supports the front end of the evaporator and supports the front part of the shroud. The inner volute backflow chamber rear wall along the main shaft is the rear compartment base that separates the inner volute backflow chamber from the rear generator chamber. If the main function of the machine is ship propulsion power, the rear compartment base on the periphery of the main body shell also supports the tail end of the evaporator tubes of the evaporator and supports the rear part of the shroud. If the main function is only power generation, the rear support is the rear outlet guard, and the central pointed cone-shaped fairing is also part of the main body shell, that is, the fixed tail cone. At the same time, the rear section of the shroud does not need to be constricted to force the flow of the heat source to accelerate to obtain the thrust.

[0085] The main shaft and its outer sleeve shaft pass through the rear compartment base and are constrained by the bearing therein. The sleeve shaft is fixed to the sun gear of the planetary gear fixed to the compartment base, and the main shaft is fixed to the gear ring of the planetary gear after passing through the sun gear. The alternately arranged compressor impellers fixed to the outer wall of the sleeve shaft and the inner wall of the straight conical tube greatly improve the compression efficiency. This is the key four.

[0086] The main shaft continues to extend rearward in the rear generator chamber outside the gear ring of the planetary gear, fixing the rotor of the power generation and starting integrated machine. If the single-source heat engine is the main function of ship propulsion power, the main shaft passes through the sealing chamber in the center of the circular cone-shaped tail end of the main body shell to fix the rear propeller. The rear section of the main body shell, together with the fairing in the center of the hub and the outlet guard, forms the rear section of the two-tipped fusiform streamline body. If the main function of the machine is only power generation, the rear propeller is cancelled, the outlet guard is the rear support that supports the tail end of the evaporator tube and supports the rear part of the shroud, and the pointed cone-shaped fairing is also part of the main body shell, that is, the tail cone. The heat source flow cross section between the main body and the shroud does not need to be constricted, and it does not need to be forced to accelerate to obtain the thrust.

[0087] The single-source heat engine of the present application is similar in appearance to a turbojet engine without afterburner. It has a waist-drum-shaped protective cover with openings in front and back and is equipped with a front and back support. Inside the protective cover is a streamlined main body with a barrel-shaped middle section and tapered ends, which is coaxial with the protective cover and maintains a proper distance from the cover to allow ambient heat source to flow through and heat the annular longitudinal low-boiling refrigerant evaporation pipes. The front ends of all evaporation pipes are bent inward and fixed to the outer wall of the annular gas collection chamber and are connected to the front support by a rib plate. The refrigerant liquid flow core pipe at the center of each evaporation pipe extends into the liquid collection chamber at the outlet of the small turbine driven by the high-pressure liquid flow of the driving compressor rotating in the annular gas collection chamber. The liquid flow core pipe extends along the axis of the evaporation pipe to the rear end, where it is connected to the regulating valve. The rear end of the evaporation pipe is connected to the rear support. The front and rear supports connect the main body and the protective cover into a whole. Inside the main body connected to the front and rear supports is a front and back cabin partition base, which divides the main body into three sections. The front cabin contains the main generator, the middle cabin contains the annular gas collection chamber and the annular liquid collection chamber, the compressor and the small turbine driven by the compressor. The heat exchange chamber, the radiator inside the heat exchange chamber, the turbine, the compressor, the inner return flow chamber with the turbine outlet 180 degrees inwardly folded back to the compressor inlet, and the generator-starting integrated machine in the back cabin are all connected to the main shaft. The driven spline shaft of the clutch is connected to the rear propeller, and the driving spline hub is connected to the tail end of the main shaft. The main shaft is connected to the generator-starting integrated machine rotor in front, the planet gear ring is connected to the planet carrier on the back cabin partition base, the sleeve shaft is connected to the sun gear at one end and is stopped at the neck of the straight taper cylinder at the other end, which is also the power output shaft of the main turbine and the slender neck of the straight taper cylinder of the compressor housing, and then it passes through the front cabin partition base and is constrained by the bearing in the base to connect the front cabin generator rotor, and then it passes through the front sealing chamber and is finally connected to the front propeller. The outer wall of the straight taper cylinder is connected to the multi-stage turbine impeller, which is alternately arranged with the static (guide) impeller connected to the inner wall of the main body shell. The inner wall of the taper cylinder is connected to the multi-stage impeller of the compressor, which is alternately arranged with the counter-rotating multi-stage impeller connected to the outer sleeve shaft of the main shaft. The inlet end of each liquid flow pipe of the radiator in the heat exchange chamber before the turbine is connected to the neck of the straight taper cylinder and the outlet end is connected to the inlet of the small turbine driven by the compressor hub. The small turbine is located outside the slender neck of the straight taper cylinder connected to the main shaft, the guide impeller is connected to the outer wall of the slender neck, and the alternating dynamic impeller is connected to the inner wall of the compressor hub. The rear end of the compressor hub is constrained by the one-way bearing and high-pressure dynamic seal ring on the radiator base outside the neck of the taper cylinder, and the front section is constrained by the bearing and high-pressure dynamic seal ring on the outer wall of the liquid collection chamber in the front cabin partition base. The small turbine is connected to the high-pressure jet of the radiator at the inlet and is connected to the liquid collection chamber at the outlet. The liquid collection chamber is connected to the liquid flow core pipe at the center of each evaporation pipe through the front cabin partition base and the front support.

[0088] Thus, when starting, the required power supply is connected to the starting motor, and at the same time, the liquid refrigerant is injected from the storage tank to the collecting chamber. The liquid refrigerant, under the drive of the compressor, enters the liquid flow core tube at the center of the evaporating pipe, and after the end control valve controls the release, absorbs the heat of the environmental heat source transmitted by the evaporating pipe wall, evaporates and expands to the gas collecting chamber, and further pressurizes by the compressor to the heat exchange chamber, absorbs the heat of the heat dissipation pipe, and then impacts the main turbine rotor impeller to work. Along the way, the rotor blades and straight conical surface cylinder shaft guide the condensed heat from the center of the compressor into the inner volute return chamber, which is immediately sucked into the compressor. The compressed refrigerant flows to the turbine through the straight conical surface cylinder and the impeller fixed thereon, and then flows to the heat exchanger pipe of the heat exchange chamber, and the high-pressure refrigerant is liquefied by heat dissipation, and then impacts the small turbine in the hub of the high-speed rotating compressor, and the outlet is the collecting chamber. Thus, the cycle is continuously repeated, and after stable operation, the starting motor power supply can be disconnected, and the external source can be continuously driven by the main shaft output power to drive the propeller and / or the generator. In addition to the need for regular maintenance due to mechanical wear, it can continue to operate.

[0089] If the machine needs to be stopped, the output line of the electric motor is disconnected, and the liquid refrigerant in the collecting chamber is quickly extracted to the storage tank. Since the amount of refrigerant in the machine is too small to sustain the cycle, the machine automatically stops.

[0090] The generator set of the present application can also be placed high above the city to eliminate the heat island effect, and can also be used to create a local cool atmosphere for large-scale celebration activities. The present application can even be used as a tool for artificial intervention in weather, which can generate electricity and cause precipitation in areas with long-term drought and little rain. The present application can also be used as a tool for fresh water production, and can also produce sea ice while generating electricity. The generator of the present application can also be installed on a train to provide power for it, without the need to pull an electric network along the way.

[0091] The above describes the present application and its embodiments, which are not limited, and the actual protection scope is not limited thereto. Any changes or replacements within the technical scope disclosed by the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
