Description

Technical Field

[0001] This invention belongs to the field of multifunctional power supply technology, specifically a multifunctional power supply device based on methanol fuel and a multiphase generator. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the search for clean and efficient alternative energy sources has become a research hotspot in the engine field. Methanol, as a promising alternative fuel, has advantages such as wide availability, low cost, and clean combustion.

[0003] A methanol generator set is an internal combustion engine-driven power generation device that uses methanol (CH3OH) as fuel. It generates electricity by burning methanol with air to release heat, which drives the crankshaft to rotate and power the generator. It is highly environmentally friendly and economical, and because methanol is a renewable resource, it is gradually replacing fuel-fired generator sets and is being used in industrial sectors and emergency power supply scenarios.

[0004] During the operation of a methanol generator set, both the combustion and electrochemical reactions of methanol generate a significant amount of heat. Therefore, heat dissipation has become a key factor restricting the stable and efficient operation of the methanol generator set. Traditional air-cooling methods are significantly affected by ambient temperature. In high-temperature environments, the air itself is warmer, reducing its heat absorption capacity and resulting in poor heat dissipation, failing to meet the cooling requirements of the unit. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional power supply device based on methanol fuel and a multiphase generator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional power supply device based on methanol fuel and a multiphase generator, comprising a housing, wherein a methanol tank, an engine and a generator are disposed inside the housing, a silencer compartment is disposed above the engine and the generator, and a cooling component is disposed inside the housing;

[0007] The cooling component includes a water tank chamber located inside the housing. There are two water tank chambers, which are symmetrically distributed on the front and rear sides of the methanol tank. Air inlets are evenly provided on the inner walls of the front and rear sides of the housing. A fan is installed on the top of the housing.

[0008] The tank is equipped with a circulation pump, and both ends of the circulation pump are connected to pipes. One of the connecting pipes has atomizing nozzles evenly installed on its outer wall. The atomizing nozzles are located above the interior of the water tank. The other connecting pipe is embedded in the bottom of the water tank.

[0009] As a further technical solution of the present invention, a filter screen is fixedly installed inside the water tank chamber, and a cleaning component is provided at the top of the filter screen.

[0010] As a further technical solution of the present invention, a guide plate is provided on one side of the water tank chamber, and through holes are uniformly opened on the inner wall of the bottom of the guide plate.

[0011] As a further technical solution of the present invention, the guide plate is provided to protrude on the side away from the water tank chamber.

[0012] As a further technical solution of the present invention, a first moisture-absorbing plate is installed on the side wall of the guide plate.

[0013] As a further technical solution of the present invention, the inner wall of the bottom of the guide plate is provided with a guide groove, and the guide groove is evenly distributed.

[0014] As a further technical solution of the present invention, the cleaning component includes a brush plate disposed at the top of the filter screen, the brush plate being slidably installed on the inner wall of the water tank chamber, and a reciprocating screw being threadedly connected to the inner wall of the brush plate, the reciprocating screw being rotatably installed on the inner wall of the tank body through the interior of the water tank chamber.

[0015] The housing is equipped with a dual-axis motor. Both ends of the dual-axis motor are equipped with a second rotating shaft. One end of one of the second rotating shafts is fixedly connected to a first gear. The top of the first gear is meshed with a second gear. A third bevel gear is fixedly installed on one side of the second gear. The top of the third bevel gear is meshed with a fourth bevel gear. The fourth bevel gear is fixedly installed on one end of a reciprocating lead screw.

[0016] As a further technical solution of the present invention, both ends of the filter screen are provided with collection grooves.

[0017] As a further technical solution of the present invention, a second moisture-absorbing plate is provided between the water tank chamber and the guide plate. The second moisture-absorbing plate is uniformly installed in a ring array on the outer wall of the first rotating shaft. The first rotating shaft is rotatably installed inside the tank body through a rotating assembly.

[0018] As a further technical solution of the present invention, the rotating assembly includes a second bevel gear fixedly installed at one end of a first rotating shaft, a first bevel gear meshing with one side of the second bevel gear, and the first bevel gear fixedly installed at one end of the second rotating shaft.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention utilizes a cooling component. When the fan operates, negative pressure is generated in the water tank chamber, drawing in outdoor air through the air inlet and then dissipating it into the tank. This dissipates heat from the internal components before being discharged, thus achieving cooling. Simultaneously, a circulating pump is activated, drawing water from the tank chamber via a connecting pipe and atomizing it through a spray nozzle. When outdoor gas passes through the water, the water's high specific heat capacity absorbs a significant amount of heat, significantly reducing the gas temperature. This cooled gas is then blown onto the power generation device, more quickly removing the heat generated by the device. Compared to simple air cooling, this method greatly improves heat dissipation efficiency and ensures the device's cooling requirements are met even in high-temperature environments.

[0021] 2. This invention, through the design of the cleaning components, utilizes a dual-axis motor to drive a second rotating shaft during operation. The rotation of the second rotating shaft drives the rotation of a first gear, which in turn drives the rotation of a second gear. The second gear then drives the rotation of a third bevel gear, which in turn drives the rotation of a fourth bevel gear. The fourth bevel gear, in turn, drives a reciprocating screw. The reciprocating screw causes the brush plate to move back and forth on the top of the filter screen, preventing water from carrying suspended particles or dust and other impurities that might otherwise clog the filter screen pores, leading to increased filtration resistance and decreased flow rate. The reciprocating movement of the brush plate, through mechanical friction, continuously scrapes away blockages on the filter screen surface, keeping the pores clear and thus maintaining a stable filtration flow rate and efficiency.

[0022] 3. By setting up a rotating component, the present invention drives the second rotating shaft to rotate during operation via a dual-axis motor. The rotation of the second rotating shaft drives the rotation of the first bevel gear, which in turn drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first rotating shaft, which in turn drives the second moisture-absorbing plate to rotate between the water tank chamber and the guide plate. This prevents local saturation and failure, and can significantly improve its moisture absorption efficiency and extend its service life. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown in the embodiment of the present invention, a multifunctional power supply device based on methanol fuel and a multiphase generator includes a housing 1. The housing 1 is equipped with a methanol tank 2, an engine 3 and a generator 4. A muffler compartment 5 is provided above the engine 3 and the generator 4. A cooling component is provided inside the housing 1.

[0034] The cooling component includes a water tank chamber 6 installed inside the housing 1. There are two water tank chambers 6, which are symmetrically distributed on the front and rear sides of the methanol tank 2. Air inlets 7 are evenly opened on the inner walls of the front and rear sides of the housing 1. A fan 29 is installed on the top of the housing 1.

[0035] A circulation pump 8 is installed inside the housing 1. Both ends of the circulation pump 8 are connected to pipes 9. Atomizing nozzles 10 are evenly installed on the outer wall of one of the connecting pipes 9. The atomizing nozzles 10 are located above the inside of the water tank chamber 6. The other connecting pipe 9 is embedded in the bottom of the water tank chamber 6.

[0036] This device can ensure the air volume required for the engine 3 to operate at full load by introducing air from both the front and rear sides of the housing 1.

[0037] Ventilation holes corresponding to air inlets 7 are provided on both sides of the top of the water tank chamber 6;

[0038] By setting up the cooling components, when the fan 29 is working, the water tank chamber 6 generates negative pressure, and outdoor air is drawn into the water tank chamber 6 through the air inlet 7 and then discharged into the box 1. After the device inside the box 1 is cooled, the air is discharged, thus completing the cooling process.

[0039] Simultaneously, the circulating pump 8 is activated, connecting to the water tank chamber 6 via the connecting pipe 9 to draw water, which is then atomized and discharged through the atomizing nozzle 10. When outdoor gas passes through the water, the water, with its high specific heat capacity, absorbs a large amount of heat from the gas, significantly reducing its temperature. The low-temperature gas is then blown towards the power generation unit, which can more quickly remove the heat generated by the unit. Compared to simple air cooling, this significantly improves heat dissipation efficiency and ensures the unit's heat dissipation requirements even in high-temperature environments.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, a filter screen 11 is fixedly installed inside the water tank chamber 6, and a cleaning component is provided at the top of the filter screen 11.

[0041] The water source is filtered after contact with air and then recycled.

[0042] like Figure 2 , Figure 3 and Figure 7 As shown, a guide plate 12 is provided on one side of the water tank chamber 6, and through holes 13 are evenly opened on the inner wall of the bottom of the guide plate 12.

[0043] The guide plate 12 guides the water-cooled low-temperature gas to prevent it from blowing directly and making it difficult to contact the devices inside the housing 1.

[0044] like Figure 2 and Figure 7 As shown, the baffle plate 12 is protruding to the side away from the water tank chamber 6.

[0045] Blowing the low-temperature gas downwards increases the contact area with the devices inside the housing 1, thereby improving the heat dissipation effect.

[0046] like Figure 2 and Figure 7 As shown, a first moisture-absorbing plate 14 is installed on the side wall of the guide plate 12.

[0047] The first moisture-absorbing plate 14 is a silicone plate with a large number of tiny pores, forming a huge adsorption surface. It can capture water in the air through physical adsorption and adsorb moisture in the low-temperature gas that passes through the water, thereby minimizing the moisture in the low-temperature gas, preventing moisture from affecting heat dissipation, and protecting the power generation device.

[0048] like Figure 7 As shown, the inner wall of the bottom of the guide plate 12 is provided with guide grooves 15, and the guide grooves 15 are evenly distributed.

[0049] The bottom of the guide channel 15 fits against the outer wall of the water tank chamber 6, forming a groove;

[0050] When the low-temperature gas comes into contact with the guide plate 12, if water condenses on the surface of the guide plate 12, it will be guided to the bottom for collection through the guide channel 15.

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the cleaning assembly includes a brush plate 27 disposed at the top of the filter screen 11. The brush plate 27 is slidably mounted on the inner wall of the water tank chamber 6. A reciprocating screw 26 is threadedly connected to the inner wall of the brush plate 27. The reciprocating screw 26 passes through the interior of the water tank chamber 6 and is rotatably mounted on the inner wall of the tank body 1.

[0052] The housing 1 houses a dual-axis motor 18. Both ends of the dual-axis motor 18 are equipped with second rotating shafts 19. One end of one of the second rotating shafts 19 is fixedly connected to a first gear 22. The top of the first gear 22 is meshed with a second gear 23. A third bevel gear 24 is fixedly installed on one side of the second gear 23. The top of the third bevel gear 24 is meshed with a fourth bevel gear 25. The fourth bevel gear 25 is fixedly installed on one end of the reciprocating lead screw 26.

[0053] During operation, the cleaning components are configured such that a dual-axis motor 18 drives a second rotating shaft 19, which in turn drives a first gear 22, which in turn drives a second gear 23, which in turn drives a third bevel gear 24, which in turn drives a fourth bevel gear 25, which in turn drives a reciprocating screw 26. The reciprocating screw 26 then moves a brush plate 27 back and forth across the top of the filter screen 11. This prevents water from carrying suspended particles or dust and other impurities that may be present in the air after contact with the filter screen. These impurities would gradually clog the pores of the filter screen 11, leading to increased filtration resistance and decreased flow rate. The reciprocating movement of the brush plate 27, through mechanical friction, continuously scrapes away the blockages on the surface of the filter screen 11, keeping the pores clear and thus maintaining a stable filtration flow rate and efficiency.

[0054] like Figure 6 As shown, both ends of the filter 11 are provided with collection grooves 28.

[0055] The impurities brushed off by the brush plate 27 are collected through the collection tank 28.

[0056] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a second moisture-absorbing plate 16 is provided between the water tank chamber 6 and the guide plate 12. The second moisture-absorbing plate 16 is evenly installed in a ring array on the outer wall of the first rotating shaft 17. The first rotating shaft 17 is rotatably installed inside the box body 1 through a rotating assembly.

[0057] The second moisture-absorbing plate 16 is made of bamboo charcoal, modified porous ceramic or activated alumina honeycomb, which can absorb moisture in the air and has good ventilation.

[0058] When the low-temperature gas is discharged from the water tank chamber 6 and guided downward by the guide plate 12, it comes into contact with the second moisture-absorbing plate 16, and the second moisture-absorbing plate 16 adsorbs the moisture in the gas again.

[0059] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the rotating assembly includes a second bevel gear 21 fixedly mounted on one end of a first rotating shaft 17, a first bevel gear 20 meshing with one side of the second bevel gear 21, and the first bevel gear 20 fixedly mounted on one end of a second rotating shaft 19.

[0060] By configuring the rotating assembly, during operation, the dual-axis motor 18 drives the second rotating shaft 19 to rotate. The rotation of the second rotating shaft 19 drives the first bevel gear 20 to rotate, which in turn drives the second bevel gear 21 to rotate. The rotation of the second bevel gear 21 drives the first rotating shaft 17 to rotate, and the rotation of the first rotating shaft 17 drives the second moisture-absorbing plate 16 to rotate between the water tank chamber 6 and the guide plate 12. This prevents local saturation and failure, significantly improving its moisture absorption efficiency and extending its service life.

[0061] Working principle and usage process:

[0062] During operation, the ventilator 29 creates negative pressure in the water tank chamber 6, drawing outdoor air into the water tank chamber 6 through the air inlet 7. At the same time, the circulation pump 8 is started, and water in the water tank chamber 6 is drawn through the connecting pipe 9 and atomized and discharged through the atomizing nozzle 10. When the outdoor gas passes through the water, it absorbs a large amount of heat from the gas, causing the gas temperature to drop significantly.

[0063] Low-temperature gas is discharged from the water tank chamber 6 and blown to one side of the guide plate 12. The first moisture-absorbing plate 14 adsorbs the moisture in the low-temperature gas passing through the water, and the low-temperature gas is blown downward to contact the second moisture-absorbing plate 16, where the second moisture-absorbing plate 16 adsorbs the moisture in the gas again.

[0064] Simultaneously, the second rotating shaft 19 is driven to rotate by the dual-axis motor 18. The rotation of the second rotating shaft 19 drives the rotation of the first gear 22, which in turn drives the rotation of the second gear 23. The rotation of the second gear 23 drives the rotation of the third bevel gear 24, which in turn drives the rotation of the fourth bevel gear 25. The rotation of the fourth bevel gear 25 drives the rotation of the reciprocating screw 26. When the reciprocating screw 26 rotates, it drives the brush plate 27 to move back and forth at the top of the filter screen 11, scraping away the blockages on the surface of the filter screen 11 and collecting them in the collection groove 28.

[0065] At the same time, the rotation of the second rotating shaft 19 drives the rotation of the first bevel gear 20, the rotation of the first bevel gear 20 drives the rotation of the second bevel gear 21, the rotation of the second bevel gear 21 drives the rotation of the first rotating shaft 17, and the rotation of the first rotating shaft 17 drives the second moisture-absorbing plate 16 to rotate between the water tank chamber 6 and the guide plate 12 to prevent local saturation and failure.

[0066] After the low-temperature gas is absorbed by the first moisture-absorbing plate 14 and the second moisture-absorbing plate 16, it is blown through the through hole 13 to the surface of the device inside the box 1, where it is cooled down and then discharged from the device.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
