Description

Technical Field

[0001] The invention belongs to the field of methanol generators, and in particular relates to a small portable energy-saving generator set powered by methanol. Background Art

[0002] A methanol generator set uses methanol as fuel to generate electricity. With the continuous growth of global energy demand and increasingly severe environmental issues, new energy power generation systems have become a focus of attention. As a new energy fuel, methanol offers advantages such as high calorific value, widespread availability, and clean combustion. Methanol generator sets use methanol as fuel to generate electricity through a chemical reaction, offering environmentally friendly, efficient, and sustainable benefits.

[0003] The existing methanol generator sets can basically meet the use needs, but they still have certain shortcomings:

[0004] Due to the low flash point and large latent heat of vaporization of methanol, it is difficult to cold start compared to gasoline. The mainstream cold start mode on the market is to start with gasoline and then switch to methanol working mode. This mode still uses some gasoline, which will pollute the air. Therefore, the environmental protection effect of the methanol generator set is greatly reduced. Summary of the Invention

[0005] The purpose of the present invention is to provide a small portable energy-saving methanol-powered generator set, aiming to solve the technical problem of difficult cold start of methanol generator sets in the prior art.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0035] Example 1

[0036] like Figure 1-Figure 5 As shown, a small portable energy-saving methanol-powered generator set provided by the present invention includes an upper support frame 1 and a lower support frame 8, a plurality of rollers 9 are installed at the bottom of the lower support frame 8, a mounting plate 10 is fixedly installed on the upper support frame 1 through a fixing rod 13, a methanol engine 12 and a generator 4 are fixedly installed on the mounting plate 10, the output end of the methanol engine 12 is connected to the input end of the generator 4, a methanol tank 3 is fixedly installed on the upper support frame 1, one end of the discharge pipe of the methanol tank 3 is connected to a methanol pump, one end of the methanol pump is connected to the methanol pipe in the methanol engine 12, a methanol filter is provided between the methanol pump and the methanol tank 3, methanol is stored in the delivery pipe methanol tank 3, and the methanol pump Methanol is extracted from the methanol tank 3 and transported to the methanol pipe in the methanol engine 12. The methanol engine 12 operates with methanol as fuel. The methanol engine 12 drives the input end of the generator 4 to rotate, which in turn enables the generator 4 to generate electrical energy. A control panel 2 is also installed on the upper support frame 1. The control panel 2 is provided with a main switch for starting and shutting down the methanol engine 12, a display screen for displaying the voltage and current of the electrical energy generated by the generator 4, a socket for outputting electrical energy, and a socket switch for controlling the opening and closing of the socket. A battery 11 is also installed on the mounting plate 10. The battery 11 is used to power the control panel 2 so that the control panel 2 can control the methanol engine 12 when the methanol engine 12 is not started.

[0037] An air extraction mechanism 6 is fixedly mounted on the top of the lower support frame 8. The input end of the air extraction mechanism 6 is connected to the upper support frame 1. A shock-absorbing spring 5 is connected between the air extraction mechanism 6 and the upper support frame 1. A baffle 14 adapted to the shock-absorbing spring 5 is provided on the upper support frame 1.

[0038] A heat storage component 7 is fixedly installed at the bottom of the methanol tank 3. The output end of the exhaust mechanism 6 is connected to the heat storage component 7. When the methanol engine 12 vibrates, the exhaust mechanism 6 is used to extract the heat generated by the methanol engine 12 and provide the heat to the heat storage component 7. The heat storage component 7 can store heat and release heat when needed (when the temperature is low) to heat the methanol in the methanol tank 3, thereby gasifying the methanol and enabling the methanol engine 12 to start smoothly.

[0039] This device does not need to use gasoline to start, but can be started with a single fuel (methanol), which is more environmentally friendly. After starting the device to generate electricity, the vibration of the methanol engine 12 during operation is used as power to extract the heat generated by the methanol engine 12 during operation, and the heat is temporarily stored in the heat storage component 7. When the temperature is low, the heat storage component 7 is started, and the heat storage component 7 can release the heat to heat the methanol in the methanol tank 3. Compared with the use of electric heating in the prior art, this device is more energy-efficient, and the heat storage component 7 can be recycled, which can save a lot of electricity and is energy-saving and environmentally friendly.

[0040] The present invention provides a small portable energy-saving methanol-powered generator set. In this embodiment, the heat storage component 7 includes an insulating shell 79 fixedly mounted on the bottom of the methanol tank 3. The insulating shell 79 is provided with a through hole 78 for the feed pipe to pass through. The side of the insulating shell 79 contacting the bottom of the methanol tank 3 is made of a heat-conducting material, and the other sides of the insulating shell 79 are made of a heat-insulating material. A partition 76 is fixedly connected to the interior of the insulating shell 79. The partition 76 divides the interior of the insulating shell 79 into a reagent chamber and a liquid chamber. The output end of the exhaust mechanism 6 is connected to the reagent chamber. A hydrated material, such as MgSO4·7H2O, CaCl2·6H2O, and MgCl2·6H2O, is placed in the reagent chamber. Heating the hydrated material will destroy its chemical bonds with water molecules, and the water molecules will be separated in the form of vapor, absorbing a large amount of heat. Water vapor or liquid water is introduced into the dehydrated material, and the water molecules will re-combine with the material to form hydrates, which will release the stored heat.

[0041] The partition 76 is provided with a plurality of first through holes 74 for connecting the medicine chamber and the liquid chamber. The generated water vapor will flow from the first through holes 74 to the liquid chamber. To prevent the water vapor from condensing and returning to the medicine chamber, the heat storage assembly 7 further includes a shielding assembly that can close and open the first through holes 74.

[0042] A plurality of exhaust one-way valves 71 are provided on the insulating shell 79, and the plurality of exhaust one-way valves 71 are all connected to the liquid cavity. The inlet of the exhaust one-way valve 71 is provided with a hydrophobic breathable membrane, such as a fluorinated ePTFE membrane, a hydrophobic MOFs membrane, a graphene / PDMS composite membrane, a PCTFE membrane, a hydrophobic polyolefin membrane, etc. The hydrophobic breathable membrane will block the passage of water vapor, while air can pass through smoothly.

[0043] Specifically, when the generator set is started, the first through hole 74 is opened by the shielding component at the same time. When the generator set is running, the methanol engine 12 will vibrate and generate a large amount of heat. The methanol engine 12 will drive the upper support frame 1 to vibrate, and the upper support frame 1 will drive the input end of the exhaust mechanism 6 to move. The exhaust mechanism 6 will extract the hot air around the methanol engine 12 and transport it to the medicine cavity in the heat-insulating shell 79. The hydrated material in the medicine cavity absorbs heat and generates water vapor. The water vapor flows from the first through hole 74 to the liquid cavity along with the air. The air passes through the hydrophobic breathable membrane and is discharged from the exhaust one-way valve 71, while the water vapor remains in the liquid cavity.

[0044] When the generator set is turned off, the shielding assembly closes the first through hole 74. Since the top of the heat-insulating shell 79 is made of a heat-conducting material, when the external ambient temperature is low, the temperature in the liquid cavity also decreases, and the water vapor condenses into liquid water. However, due to the obstruction of the shielding assembly, the water is temporarily stored in the liquid cavity. When the generator set needs to be used, the shielding assembly is first controlled to open the first through hole 74. The water in the liquid cavity flows into the reagent cavity through the first through hole 74, and the water re-combines with the material to form a hydrate. At the same time, the stored heat is released. The heat is transferred to the bottom of the methanol tank 3 through the heat-conducting material on the top of the heat-insulating shell 79, thereby heating the methanol in the methanol tank 3 and gasifying the methanol, which is convenient for starting the methanol engine 12.

[0045] After the methanol engine 12 is started, the heat generated by the methanol engine 12 will be stored in the heat storage component 7 for next use. The heat storage component 7 can be recycled, which can save a lot of electricity.

[0046] The present invention provides a small portable energy-saving generator set powered by methanol. In this embodiment, the shielding assembly includes a baffle 75 slidably mounted on the top of a partition 76, and the baffle 75 is provided with a plurality of second through holes 77 that are compatible with the first through holes 74. A micro servo motor 72 is fixedly mounted on the side of the heat insulation shell 79, and the output shaft of the micro servo motor 72 is fixedly connected to a screw rod 73, and one end of the screw rod 73 extending into the liquid chamber is threadedly connected to the baffle 75.

[0047] The micro servo motor 72 drives the screw rod 73 to rotate, and the screw rod 73 can drive the baffle 75 to move horizontally. When the second through hole 77 moves to the side of the first through hole 74, the first through hole 74 is closed. When the second through hole 77 and the first through hole 74 are connected, the first through hole 74 is opened.

[0048] The present invention provides a small portable energy-saving methanol-powered generator set. In this embodiment, the exhaust mechanism 6 includes a ventilation cylinder 63 fixedly mounted on the top of the lower support frame 8. A piston block 66 is slidably mounted inside the ventilation cylinder 63. One end of the upper support frame 1 passes through the ventilation cylinder 63 and is fixedly connected to the top of the piston block 66. The shock-absorbing spring 5 is arranged between the ventilation cylinder 63 and the baffle 14.

[0049] The side of the ventilator 63 is provided with two groups of air ports, each group of air ports includes two air holes, and the two air holes in the same group are respectively located on both sides of the piston block 66;

[0050] Two groups of air ports, namely an air inlet and an air outlet, are connected to the same pipe, namely an air extraction pipe 62 and an air outlet pipe 61. One end of the air extraction pipe 62 extends to the side of the methanol engine 12. The air extraction pipe 62 is provided with multiple air inlet holes 64 for extracting air. One end of the air outlet pipe 61 is connected to the medicine chamber in the heat-insulating shell 79.

[0051] In order to achieve uninterrupted air supply, a one-way valve assembly 65 is provided between each of the air holes and the pipeline.

[0052] Specifically, the one-way valve assembly 65 connected to the exhaust pipe 62 is an air inlet valve, and the one-way valve assembly 65 connected to the outlet pipe 61 is an air outlet valve. For ease of understanding, the four one-way valve assemblies 65 are named as follows: Figure 5 As shown, from top to bottom and from left to right, the four one-way valve assemblies 65 are respectively marked as an upper air outlet valve, an upper air inlet valve, a lower air outlet valve and a lower air inlet valve;

[0053] During operation, when the piston block 66 rises, the lower air inlet valve and the upper air outlet valve are opened, and the upper air inlet valve and the lower air outlet valve are closed, and the air in the ventilation cylinder 63 can be discharged from the upper air outlet valve to the medicine chamber; when the piston block 66 descends, the lower air inlet valve and the upper air outlet valve are closed, and the upper air inlet valve and the lower air outlet valve are opened, and the air in the ventilation cylinder 63 can be discharged from the lower air outlet valve to the medicine chamber. Therefore, the device can realize uninterrupted air supply without worrying about the water vapor generated in the medicine chamber being extracted, thereby improving the service life of the heat storage component 7.

[0054] The present invention provides a small portable energy-saving generator set powered by methanol. In this embodiment, the one-way valve assembly 65 includes a shell 651 arranged between the pipeline and the air hole, and a mounting ring 653 is fixedly installed inside the shell 651. The side of the mounting ring 653 is hinged with an air blocking piece 652, and the air blocking piece 652 seals the mounting ring 653.

[0055] Specifically, the difference between the air inlet valve and the air outlet valve lies in the position of the air blocking piece 652. The air blocking piece 652 of the air inlet valve is located on the side of the mounting ring 653 close to the axis of the ventilation cylinder 63, and the air blocking piece 652 of the air outlet valve is located on the side of the mounting ring 653 away from the axis of the ventilation cylinder 63. During operation, such as when the piston block 66 rises, the volume of the space inside the ventilation cylinder 63 at the bottom of the piston block 66 gradually increases, causing the air pressure inside it to decrease. The outside air will push the air blocking piece 652 of the lower air inlet valve to open, and the air enters the ventilation cylinder 63 from the mounting ring 653, while the space above the piston block 66 is gradually compressed, and its air pressure increases. The larger air pressure pushes the air blocking piece 652 of the upper air outlet valve to open, and the gas is discharged from the mounting ring 653. When the piston block 66 descends, the operating principle of the one-way valve assembly 65 is similar and will not be repeated.

[0057] like Figure 6-Figure 7 As shown, a small portable energy-saving methanol-powered generator set provided by the present invention. In this embodiment, the methanol engine 12 includes a starter, a methanol pipe, an electronic throttle, a cylinder, a spark plug, an intake pipe, an exhaust pipe, etc. The starter is connected to the body, the intake pipe and the exhaust pipe are connected to the two ends of the cylinder head, the electronic throttle is installed at one end of the intake pipe, one end of the methanol pipe is connected to the methanol pump, and the other end of the methanol pipe is connected to a methanol injector, the methanol injector is installed on the intake pipe and communicates with the intake pipe, the spark plug is installed on the cylinder head, and the methanol engine 12 also includes a preheating plug, which is installed on the cylinder head.

[0060] The present invention provides a small portable energy-saving methanol-powered generator set. In this embodiment, an electronic control unit (ECU) is installed on the control panel 2. The ECU is connected to various sensors and actuators, and a battery 11 supplies power to the ECU.

[0061] The control logic of the ECU: after power-on, the current cylinder temperature is detected (equivalent to the ambient temperature at the beginning). If it is lower than a certain value, the preheating plug starts to work. After reaching the set value (the cylinder temperature setting value is different under different ambient temperatures), the methanol pump and the intake preheating grid start to work. After the starting conditions are met, the ECU enters the starting mode and sends a signal to the starting relay. Then the starter drags the flywheel. The ECU detects the speed and the methanol engine 12 starts to work. After successful starting, the preheating plug and the intake preheating grid stop working, and the methanol engine 12 enters the normal working mode.

[0062] The methanol pump is a key component to ensure the normal operation of the engine. It works all the time during the engine start-up and operation. Through the pressure stabilizing valve, the entire methanol supply pipeline is kept at a certain pressure.

[0063] The functions of each sensor will not be elaborated here, as they are the same as those of the sensors used in the multi-point electronic injection system of a four-cylinder gasoline engine.

[0064] If the methanol engine 12 is a single-cylinder engine, it has one cylinder head and one methanol injector. If it is a two-cylinder engine, it has two cylinder heads and two methanol injectors. Regardless of whether it is a single-cylinder engine or a two-cylinder engine, each cylinder head has two preheating valves (for cold starting).

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
