Technical Field
[0001] This invention relates to the field of energy storage power station technology, and in particular to a temperature regulation system for a diesel-storage hybrid power plant and the diesel-storage hybrid power plant itself. Background Technology
[0002] To solve the problem of emergency power supply, the technical solution of integrated diesel and storage equipment is generally adopted. Existing integrated diesel and storage equipment all appear in the form of containerized power stations.
[0003] Further information related to the above technical solutions can be found in the following documents:
[0004] Patent CN114076027A discloses a containerized power station, which includes: a container body, the container body being divided into an electrical equipment compartment and a generator set compartment, with a louver on each side of the generator set compartment; a diesel generator set, which is located in the generator set compartment, the generator set compartment being equipped with an exhaust assembly, the exhaust assembly including a first air outlet, a water cooler and a cooling fan, the first air outlet being located at the top of the container body, the water cooler being located in the air outlet direction of the cooling fan; and an electrical equipment assembly, which is located in the electrical equipment compartment, the electrical equipment compartment including an air conditioning unit, the electrical equipment assembly being connected to the air conditioning unit through a second air inlet, and the second air outlet being connected to the outside of the container body.
[0005] Patent CN101968401A discloses a coolant temperature control system for engine performance testing, comprising an internal coolant circulation system, a heat exchange device, a temperature monitoring and control device, and an external coolant circulation system. The internal coolant circulation system and the external coolant circulation system are respectively connected to the heat exchange device. The internal coolant circulation system is connected to the engine. The temperature monitoring and control device is respectively connected to the internal coolant circulation system, the heat exchange device, and the external coolant circulation system. The internal coolant circulation system is a closed-loop internal circulation system.
[0006] In the process of realizing this invention, the inventors discovered the following problems in the prior art:
[0007] In existing technology, engine coolant is divided into external and internal circulation, while battery devices are cooled by air. In extremely cold conditions, when the ambient temperature is below -10°C, the batteries in the battery device will become unusable, and the heat generated by the diesel generator after starting cannot be utilized, resulting in low energy efficiency. Summary of the Invention
[0008] Therefore, it is necessary to provide a temperature regulation system and a diesel-storage hybrid device to solve the technical problem that the battery in the battery device cannot be used when the environment is below -10℃, and the heat after the diesel generator is started cannot be utilized, resulting in low energy utilization efficiency.
[0009] To achieve the above objectives, in a first aspect, the inventor provides a temperature regulation system for a diesel-storage hybrid device, comprising:
[0010] A diesel generator, comprising an engine, the engine comprising an engine cooling module, the engine cooling module comprising a water pump, a thermostat and a cylinder block water jacket, the water pump, the thermostat and the cylinder block water jacket being interconnected via a first coolant pipe;
[0011] The battery device, wherein the diesel generator is electrically connected to the battery device via an energy storage converter; and
[0012] The battery device is provided with a channel through which coolant can pass. The coolant device is connected to one end of the channel via an inlet pipe, and the other end of the channel is connected to the coolant device via an outlet pipe. The coolant device provides coolant to the battery device to dissipate heat from the battery.
[0013] The engine cooling module is connected to the channel, and the engine cooling module can be used to provide coolant to the channel.
[0014] Unlike existing technologies, the above-mentioned technical solution connects the engine cooling module with the coolant in the battery device through a channel, which can provide coolant to the battery device. After the diesel generator starts, the coolant in the engine circulates internally. When the coolant temperature is around 60°C to 70°C, it can transfer the coolant from the engine to the battery device to heat the battery. After heating, the coolant is recycled, which means that the heat from the diesel generator is used to power the battery in the battery device. This effectively utilizes the temperature of the diesel generator to help the battery in the battery device reach a suitable operating temperature and improves energy efficiency.
[0015] In one embodiment of the present invention, one end of the first coolant pipe is connected to one end of the channel via a second coolant pipe, and the other end of the first coolant pipe is connected to the other end of the channel via a third coolant pipe. A first electronic valve and a second electronic valve are provided on the second coolant pipe and the third coolant pipe, and the first electronic valve and the second electronic valve are linked together.
[0016] In this way, coolant can be supplied to the coolant passage of the battery device through the cooperation of the second coolant pipe, the third coolant pipe, the first electronic valve and the second electronic valve. The first electronic valve and the second electronic valve open and close at the same time to avoid excessive pressure in the coolant passage of the battery device.
[0017] In one embodiment of the present invention, a third electronic valve is provided on the liquid inlet pipe and a fourth electronic valve is provided on the liquid outlet pipe. The third electronic valve is configured to close the liquid inlet pipe when the first electronic valve opens the second coolant pipe.
[0018] The fourth electronic valve is configured to close the outlet pipe when the second electronic valve opens the third coolant pipe.
[0019] Thus, when the coolant from the diesel generator is supplied to the battery device, the coolant temperature in the coolant device may be too low. To avoid the coolant from the diesel generator being affected by the coolant in the coolant device, the coolant from the diesel generator and the coolant in the coolant device are relatively isolated during use. Through the cooperation of the third and fourth electronic valves, the coolant from the diesel generator and the coolant in the coolant device are not interconnected, thereby improving the heating effect of the diesel generator's coolant on the battery device.
[0020] In one embodiment of the present invention, the temperature regulation system further includes a first temperature sensor, a second temperature sensor, and a controller. The first temperature sensor is used to detect the temperature of the engine cooling module, and the second temperature sensor is used to detect the temperature of the battery device. The first temperature sensor and the second temperature sensor respectively send temperature signals to the controller, and the controller controls the first electronic valve, the second electronic valve, the third electronic valve, and the fourth electronic valve according to the first temperature sensor and the second temperature sensor.
[0021] In this way, by monitoring the temperature of the engine cooling module and battery equipment, it is possible to control whether to turn on or off the diesel generator's coolant supply to the battery equipment.
[0022] In one embodiment of the present invention, the first temperature sensor is disposed inside the cylinder block water jacket, and the first temperature sensor is used to detect the real-time temperature of the coolant inside the cylinder block water jacket, and the second temperature sensor is used to detect the real-time temperature of the battery inside the battery device.
[0023] Thus, the first temperature sensor is used to detect the real-time temperature of the coolant in the cylinder block water jacket, and the second temperature sensor is used to detect the real-time temperature of the battery in the battery device, which can improve the accuracy of the temperature sensors.
[0024] In one embodiment of the present invention, the controller is configured to, when the first temperature sensor detects that the temperature of the coolant in the cylinder block water jacket exceeds a first preset value, and the second temperature sensor detects that the battery in the battery device is lower than a second preset value, cause the first electronic valve and the second electronic valve to open the second coolant pipe and the third coolant pipe, and the third electronic valve and the fourth electronic valve to close the inlet pipe and the outlet pipe.
[0025] Thus, only when the temperature of the coolant in the cylinder block water jacket exceeds 60°C and the temperature of the battery in the battery device is below -10°C can the coolant in the cylinder block water jacket be triggered to heat the battery in the battery device. Under normal circumstances, the coolant in the diesel generator cools the diesel generator engine, while the coolant in the coolant device cools the battery device.
[0026] In one embodiment of the present invention, the battery device includes a frame, two or more battery packs, and a battery management module. The two or more battery packs are arranged sequentially on the frame in a vertical direction. The battery management module is arranged on the frame. All the battery packs are electrically connected to the battery management module. The battery management module is connected to the controller.
[0027] In this way, the battery management module can detect the temperature of all batteries. The battery management module is directly connected to the controller, which can save the need for a second temperature sensor and its connection circuit. The temperature of all batteries can be obtained directly through the battery management module, making it convenient to use.
[0028] In one embodiment of the present invention, the controller is further configured to control the coolant device to provide coolant to the battery device based on the temperature signal of the battery device sent by the second temperature sensor.
[0029] In this way, the coolant supply to the battery device can be controlled based on the battery temperature signal of the monitoring battery device. When the battery temperature signal of the battery device is too low, the coolant supply to the battery device will not supply coolant, thus realizing automatic control of the coolant supply.
[0030] In one embodiment of the present invention, the engine cooling module further includes a radiator and a heater heat exchanger. The radiator and the heater heat exchanger are respectively connected to the thermostat via a fourth coolant pipe. The thermostat is used to control whether coolant enters the radiator and the heater heat exchanger.
[0031] In this way, the radiator can dissipate heat from the engine coolant, the heater heat exchanger can heat the engine coolant to prevent the coolant temperature from getting too low, and the thermostat controls whether the coolant enters the radiator or the heater heat exchanger according to the actual temperature of the coolant.
[0032] To achieve the above objectives, in a second aspect, the inventors provide a diesel-storage hybrid device, including a temperature control system as described in any of the aforementioned inventors' claims.
[0033] Unlike existing technologies, the diesel-storage hybrid device in this application connects the engine cooling module with the coolant in the battery device through a channel. This allows the device to supply coolant. After the diesel generator starts, the coolant in the engine circulates internally. When the coolant temperature is around 60°C to 70°C, it can be transferred to the battery device to heat the battery. After heating, the coolant is recycled. In other words, the heat from the diesel generator is used to power the battery in the device, effectively utilizing the temperature of the diesel generator to help the battery reach a suitable operating temperature and improve energy efficiency.

[0071] In the existing technology, the coolant of the engine 21 is divided into external circulation and internal circulation, while the battery device 3 uses air cooling to dissipate heat. Under extremely cold conditions, when the ambient temperature is below -10°C, the battery in the battery device 3 will not be usable, and the heat generated after the diesel generator 2 starts cannot be utilized, resulting in low energy utilization.
[0072] The applicant's research found that in a diesel-electric hybrid system, the engine 21 of the diesel generator 2 starts first. After starting, the coolant in engine 21 circulates within the engine 21. At this time, the temperature of the coolant can be utilized and supplied to the battery device 3 to heat the batteries, allowing them to reach their minimum operating temperature as quickly as possible. In other words, the heat from the diesel generator 2 is used by the batteries in the battery device 3, effectively utilizing the temperature of the diesel generator 2 to help the batteries in the battery device 3 reach their suitable operating temperature and improve energy efficiency.
[0073] The temperature control system and the diesel-storage hybrid device in this embodiment can be applied to the technical field of various energy storage devices.
[0074] According to some embodiments of this application, please refer to Figures 1 to 12 This embodiment relates to a temperature regulation system for a diesel-storage hybrid device, including a diesel generator 2, a battery device 3, and a coolant device 4. The diesel generator 2 includes an engine 21, and the engine 21 includes an engine cooling module. The engine cooling module includes a water pump 22, a thermostat 23, and a cylinder block water jacket 24. The water pump 22, the thermostat 23, and the cylinder block water jacket 24 are interconnected through a first coolant pipe 25.
[0075] The diesel generator 2 is electrically connected to the battery device 3 via the energy storage converter 5. The battery device 3 is provided with a channel 31 through which coolant passes. The coolant device 4 is connected to one end of the channel 31 via an inlet pipe 32, and the other end of the channel 31 is connected to the coolant device 4 via an outlet pipe 33. The coolant device 4 provides coolant to the battery device 3 to dissipate heat from the battery. The engine cooling module is connected to the channel 31 and can be used to provide coolant to the channel 31.
[0076] In this embodiment, the engine cooling module consists of a radiator 28, pipes, a water pump 22, a cooling fan 282, cooling water jackets in the cylinder block and cylinder head, and auxiliary devices. The function of the engine cooling module is to ensure that the engine 21 receives adequate cooling under any operating condition, thereby maintaining it at a suitable temperature (coolant temperature). The engine cooling module must prevent the engine 21 from overheating and also prevent it from becoming too cold in winter.
[0077] The internal and external circulation of the engine cooling module is typically controlled by a thermostat 23, which regulates the flow of coolant through the radiator 28. The thermostat 23 is installed in the coolant circulation path (usually at the outlet of the cylinder head) and automatically changes the water circulation path according to the engine load 21 and the water temperature to adjust the cooling intensity of the cooling system.
[0078] When engine 21 operates under normal hot conditions, the coolant temperature exceeds 80°C. The thermostat valve 23 opens the passage 31 leading to radiator 28, while simultaneously closing the bypass pipe to water pump 22. All coolant flows through radiator 28, forming an external circulation. Figure 2 As shown.
[0079] When the engine 21 is in a cold environment or has just started, and the coolant temperature is below 70℃, the thermostat 23 valve closes the passage 31 leading to the radiator 28, while simultaneously opening the bypass pipe leading to the water pump 22. Water in the water jacket can only flow in through the bypass hole, then through the bypass pipe into the water pump 22, and is then pumped into the engine 21 water jacket by the water pump 22. At this time, the coolant does not flow through the radiator 28, but only circulates internally between the water jacket and the water pump 22, thus preventing the engine 21 from becoming too cold. Figure 3 As shown.
[0080] In other cases, if the coolant in engine 21 is too low, it can also flow through heater heat exchanger 29, which heats the coolant.
[0081] In this embodiment, the diesel generator 2 adopts a technical solution with the fuel tank at the bottom. The diesel generator 2 itself includes a muffler, an air intake, and an exhaust port, and its exhaust port and muffler are separated from other components of the diesel generator 2.
[0082] In this embodiment, the battery device 3 is arranged in a cabinet manner, with the battery pack 35 stacked on the rack 34.
[0083] In this embodiment, the coolant device 4 is a coolant supply device that provides power for the flow of coolant. In this embodiment, the coolant device 4 supplies coolant to the battery device 3 to dissipate heat from the battery, eliminating the need for an air conditioner outdoor unit. This eliminates concerns about dust being blown into the hybrid power station by the air conditioner outdoor unit, demonstrating strong environmental adaptability. The liquid cooling uses contact-type heat dissipation, which improves the protection level and safety of the battery pack 35 without affecting the battery's heat dissipation efficiency. Simultaneously, the temperature of the battery in the battery device 3 is monitored by the first temperature sensor 71, and the controller 7 controls the coolant device 4 to supply coolant to the battery device 3. This allows for automatic control of the coolant device 4 to dissipate heat from the battery in the battery device 3, eliminating the need for manual operation and improving heat dissipation efficiency.
[0084] In this embodiment, the energy storage converter 5, a bidirectional energy storage inverter (PCS), is used in AC-coupled energy storage systems such as grid-connected energy storage and microgrid energy storage. It connects the battery bank and the power grid (or load) and is a device that enables bidirectional energy conversion. It can convert the DC power from the battery into AC power for supply to the power grid or AC loads; it can also rectify the AC power from the power grid into DC power to charge the battery. In this embodiment, the diesel generator 2 can charge the battery in the battery device 3 through the energy storage converter 5.
[0085] In this embodiment, the engine cooling module is connected to the coolant channel 31 of the battery device 3, which provides coolant to the battery device 3. After the diesel generator 2 starts, the coolant in the engine 21 circulates internally. When the coolant temperature is around 60°C to 70°C, it can transfer the coolant in the engine 21 to the battery device 3 to heat the battery. After heating, the coolant is recycled, which means that the heat from the diesel generator 2 is used by the battery in the battery device 3. This effectively utilizes the temperature of the diesel generator 2 to help the battery in the battery device 3 reach a suitable operating temperature and improves energy utilization.
[0086] The cables between the diesel generator 2, battery equipment 3, and energy storage converter 5 are installed on the top of the enclosure 1 through cable grooves 6 to prevent the cables from interfering with other structures.
[0087] According to some embodiments of this application, optionally, the engine cooling module further includes a radiator 28 and a heater heat exchanger 29. The radiator 28 and the heater heat exchanger 29 are respectively connected to a thermostat 23 through a fourth coolant pipe 30. The thermostat 23 is used to control whether coolant enters the radiator 28 and the heater heat exchanger 29.
[0088] The thermostat 23 is used to control whether the coolant enters the radiator 28 for cooling, enters the heater heat exchanger 29 for heating, or enters the internal circulation without cooling or heating.
[0089] In this way, the radiator 28 can dissipate heat from the coolant of the engine 21, and the heater heat exchanger 29 can heat the coolant of the engine 21 to prevent the coolant temperature from being too low. The thermostat 23 controls the coolant to enter the radiator 28 or the heater heat exchanger 29 according to the actual temperature of the coolant.
[0090] According to some embodiments of this application, optionally, one end of the first coolant pipe 25 is connected to one end of the channel 31 through the second coolant pipe 26, and the other end of the first coolant pipe 25 is connected to the other end of the channel 31 through the third coolant pipe 27. A first electronic valve 261 and a second electronic valve 271 are provided on the second coolant pipe 26 and the third coolant pipe 27, and the first electronic valve 261 and the second electronic valve 271 are linked together.
[0091] In this way, the coolant can be supplied to the coolant channel 31 of the battery device 3 through the cooperation of the second coolant pipe 26, the third coolant pipe 27, the first electronic valve 261 and the second electronic valve 271. The first electronic valve 261 and the second electronic valve 271 open and close at the same time to avoid excessive pressure in the coolant channel 31 of the battery device 3.
[0092] According to some embodiments of this application, optionally, a third electronic valve 281 is provided on the inlet pipe 32, and a fourth electronic valve 291 is provided on the outlet pipe 33. The third electronic valve 281 is configured to close the inlet pipe 32 when the first electronic valve 261 opens the second coolant pipe 26; the fourth electronic valve 291 is configured to close the outlet pipe 33 when the second electronic valve 271 opens the third coolant pipe 27.
[0093] Thus, when the coolant from the diesel generator 2 is supplied to the battery device 3, the coolant temperature of the coolant device 4 may be too low. To avoid the coolant from the diesel generator 2 being affected by the coolant from the coolant device 4, the coolant from the diesel generator 2 and the coolant from the coolant device 4 are relatively isolated during use. Through the cooperation of the third electronic valve 281 and the fourth electronic valve 291, the coolant from the diesel generator 2 and the coolant from the coolant device 4 are not interconnected, thereby improving the heating effect of the coolant from the diesel generator 2 on the battery device 3.
[0094] According to some embodiments of this application, optionally, the temperature regulation system further includes a first temperature sensor 71, a second temperature sensor 72, and a controller 7. The first temperature sensor 71 is used to detect the temperature of the engine cooling module, and the second temperature sensor 72 is used to detect the temperature of the battery device 3. The first temperature sensor 71 and the second temperature sensor 72 respectively send temperature signals to the controller 7. The controller 7 controls the first electronic valve 261, the second electronic valve 271, the third electronic valve 281, and the fourth electronic valve 291 based on the first temperature sensor 71 and the second temperature sensor 72.
[0095] In this way, by monitoring the temperature of the engine cooling module and the battery device 3, it is possible to control whether to turn on or off the cooling of the diesel generator 2 to heat the battery device 3.
[0096] According to some embodiments of this application, optionally, a first temperature sensor 71 is disposed inside the cylinder block water jacket 24, and the first temperature sensor 71 is used to detect the real-time temperature of the coolant inside the cylinder block water jacket 24, and a second temperature sensor 72 is used to detect the real-time temperature of the battery inside the battery device 3.
[0097] The cylinder block water jacket 24 is close to the engine block, and the coolant in the cylinder block water jacket 24 is close to the temperature of the engine block.
[0098] Thus, the first temperature sensor 71 is used to detect the real-time temperature of the coolant in the cylinder block water jacket 24, and the second temperature sensor 72 is used to detect the real-time temperature of the battery in the battery device 3, which can improve the accuracy of the temperature sensors.
[0099] According to some embodiments of this application, optionally, the controller 7 is configured to, when the first temperature sensor 71 detects that the temperature of the coolant in the cylinder block water jacket 24 exceeds a first preset value, and the second temperature sensor 72 detects that the battery in the battery device 3 is lower than a second preset value, cause the first electronic valve 261 and the second electronic valve 271 to open the second coolant pipe 26 and the third coolant pipe 27, and the third electronic valve 281 and the fourth electronic valve 291 to close the inlet pipe 32 and the outlet pipe 33.
[0100] Thus, only when the temperature of the coolant in the cylinder block water jacket 24 exceeds 60°C and the temperature of the battery in the battery device 3 is below -10°C can the coolant in the cylinder block water jacket 24 be triggered to heat the battery in the battery device 3. Under normal circumstances, the coolant of the diesel generator 2 cools the engine 21 of the diesel generator 2, while the coolant of the coolant device 4 cools the battery device 3.
[0101] According to some embodiments of this application, optionally, the battery device 3 includes a frame 34, two or more battery packs 35, and a battery management module 36. The two or more battery packs 35 are arranged sequentially on the frame 34 in a vertical direction. The battery management module 36 is arranged on the frame 34. All battery packs 35 are electrically connected to the battery management module 36. The battery management module 36 is connected to the controller 7.
[0102] The battery management module 36 is a conventional BMS battery system. It is designed to intelligently manage and maintain each battery cell, prevent overcharging and over-discharging, extend battery life, and monitor battery status.
[0103] In this embodiment, the battery management module 36 can manage the connection and control of the coolant device 4. The battery management module 36 collects the status of the battery to control whether the coolant device 4 needs to dissipate heat from the battery, whether to turn it on or off; or whether to speed up the flow of coolant to improve heat dissipation efficiency or slow down the flow of coolant to reduce heat dissipation efficiency. The battery management module 36 can provide control signals to the coolant device 4 to facilitate the use of the coolant device 4.
[0104] In this embodiment, the batteries inside the battery pack 35 are placed on the channel 31. After placement, the casing of the battery pack 35 is locked with bolts.
[0105] In this way, the battery management module 36 can detect the temperature of all batteries. The battery management module 36 is directly connected to the controller 7, which can save the second temperature sensor 72 and the connection circuit of the second temperature sensor 72. The temperature of all batteries can be obtained directly through the battery management module 36, which is convenient to use.
[0106] According to some embodiments of this application, optionally, the controller 7 is also configured to control the coolant device 4 to provide coolant to the battery device 3 based on the temperature signal of the battery of the battery device 3 sent by the second temperature sensor 72.
[0107] In this way, the coolant device 4 can be controlled to supply coolant to the battery device 3 based on the temperature signal of the battery device 3. When the battery temperature signal of the battery device 3 is too low, the coolant device 4 will not supply coolant to the battery device 3, thus realizing automatic control of the coolant device 4.
[0108] This embodiment also relates to a diesel-storage hybrid device, including a temperature regulation system as described above.
[0109] The diesel-storage hybrid equipment also includes a container 1, which is a container-type container 1. The four corners of the container 1 are provided with lifting holes for easy hoisting. All other equipment is installed inside the container 1.
[0110] In this embodiment, the housing 1 is provided with a power interface 11, the diesel generator 2 is connected to the power interface 11, and the battery device 3 is connected to the power interface 11 through the energy storage converter 5. The diesel generator 2 and the battery device 3 can provide power to external devices individually or in parallel. There is only one power interface 11, and the diesel generator 2 and the battery device 3 can be powered individually or in parallel by switching through software.
[0111] Unlike existing technologies, the diesel-storage hybrid device of this application connects the engine cooling module to the coolant in the battery device 3 via a channel 31. This allows the battery device 3 to receive coolant. After the diesel generator 2 starts, the coolant in the engine 21 circulates internally. When the coolant temperature is around 60°C to 70°C, it can transfer the coolant from the engine 21 to the battery device 3 to heat the battery. After heating, the coolant is recycled. In other words, the heat from the diesel generator 2 is used by the battery in the battery device 3, effectively utilizing the temperature of the diesel generator 2 to help the battery in the battery device 3 reach a suitable operating temperature and improve energy efficiency.
[0112] In this embodiment, the sensor uses a sensing element and a conversion element to convert a specific measured signal into a usable signal according to a certain rule and output it to meet the requirements of information transmission, processing, recording, display, and control. The sensor can sense physical quantities such as force, temperature, light, sound, and chemical composition, and can convert them into electrical quantities such as voltage and current, or into the on / off state of a circuit, according to a certain rule. A sensor generally consists of a sensing element and a conversion element, and is the primary link in realizing automatic detection and automatic control. The function of the sensor is to convert non-electrical quantities into electrical quantities or the on / off state of a circuit, thereby enabling convenient measurement, transmission, processing, and control.
[0113] In this embodiment, the controller receives signals transmitted from the sensors and controls the actuators or execution units according to the signals transmitted from the sensors. The controller refers to the master command device that controls the starting, speed regulation, braking, and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system.
[0114] In this embodiment, the execution mechanism or execution unit includes, but is not limited to, compression mechanisms, rotation mechanisms, swing mechanisms, vibration mechanisms, lifting mechanisms, cutting mechanisms, etc. It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural or procedural transformations made using the content of this specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this invention.
