Description

Technical Field

[0001] This invention relates to the field of gasoline generator technology, and more particularly to a dustproof and stable gasoline generator. Background Technology

[0002] A gasoline generator is a portable power generation device that uses gasoline as fuel and is driven by an internal combustion engine. It is compact, easy to start, and highly mobile, unrestricted by municipal power grids. It converts the chemical energy of fuel into electrical energy, providing a stable output of AC power. Widely used for outdoor work, camping, power outages, remote areas without power grids, and temporary power supply for small equipment, it is characterized by its strong applicability, simple maintenance, and controllable range, making it a commonly used emergency and mobile power supply device. With the rapid development of clean energy technologies, the drawbacks of traditional fuel-powered internal combustion engines—high emissions, high pollution, and high fossil fuel consumption—are becoming increasingly prominent. The industry is gradually upgrading towards low-carbon and zero-carbon power. Currently, hydrogen-ammonia new energy internal combustion engines are developing rapidly due to their advantages of clean combustion, low carbon emissions, and renewable energy. They replace traditional gasoline and diesel with clean fuels such as hydrogen and liquid ammonia, producing no sulfur oxides or dust emissions during combustion, significantly reducing carbon emissions and becoming an important upgrade direction in the internal combustion engine field.

[0003] The prior art publication CN118030272A provides a gasoline generator that uses an impeller on the rotor and air holes to draw in outside air for heat dissipation. The heat dissipation channel does not interfere with the combustion-related channel, reducing the impact on combustion. Since the inverter component operates at a high frequency, the inverter component is cooled first, then the stator and rotor are cooled, and then the heated air is discharged, thereby reducing the overall temperature and minimizing the possibility of damage.

[0004] Existing technologies have achieved heat dissipation for gasoline generators. However, when gasoline generators need refueling, it is necessary to manually fill the generator's fuel tank with a gasoline can held in hand. Because existing gasoline generators are not convenient for assisted positioning and automatic tilting, the operation is laborious, the refueling efficiency is low, and gasoline spillage and waste are likely to occur, as well as creating flammable and explosive safety hazards. In addition, the refueling port is left open for a long time, and external sand and dust can easily enter the fuel tank and the inside of the machine body with the air, which can easily cause oil circuit blockage, component wear, and thus affect the overall dustproof performance and operational stability of the generator.

[0005] In summary, the existing technology lacks technology for automatic refueling and dust prevention for gasoline generators. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a dustproof and stable gasoline generator.

One end of the universal joint extends through the inner wall of the sliding groove to the outside and is fixedly connected to a transmission wheel. The transmission wheel meshes with a fixed rack for transmission. A lead screw is fixedly connected to the other end of the universal joint. The top end of the lead screw is rotatably connected to the inner wall of the sliding groove. An adjusting block is threadedly connected to the outer wall of the lead screw. The two sides of the adjusting block are slidably fitted with the inner wall of the sliding groove. An adjusting rod is rotatably connected to one side of the adjusting block. The other end of the adjusting rod is rotatably connected to the oil drum placement seat.

[0013] Preferably, one end of the oil drum placement seat is rotatably connected to the top of the sliding frame, the oil drum placement seat is provided with a positioning groove, the oil drum is placed in the positioning groove, and the inner wall of the opening of the oil drum is threadedly connected to the connecting sleeve.

There is no need for manual lifting and pouring, which greatly reduces the operation intensity and improves refueling efficiency. The fuel pouring flow rate is uniform and controllable, effectively avoiding fuel spillage and waste and flammable and explosive safety hazards.

[0018] 2. By installing a drum positioning component on the drum placement seat, the drum on the drum placement seat can be positioned, so as to prevent the drum from shifting, sliding or falling off during the lifting and pouring of refueling, so as to make the fuel refueling process smooth and orderly and avoid fuel spillage and leakage due to misalignment.

[0019] 3. By installing a dustproof oil guiding component inside the fuel tank cap, the connecting sleeve connected by the elastic hose can be threaded to the opening of the fuel drum during refueling. This seals both the fuel tank and the fuel drum opening, effectively preventing external dust from entering the fuel system. This eliminates problems such as fuel system blockage and component wear caused by sand and dust contaminating the fuel, avoids fuel evaporation, leakage, and spillage, reduces flammable and explosive safety hazards, meets the dustproof design requirements of the generator, further improves the overall dustproof performance, ensures stable generator operation, and extends the service life of the equipment.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The dustproof and stable gasoline generator shown includes a body 1, a fuel tank 2 fixedly mounted on the body 1, a fuel tank cap 3 threadedly connected to the fuel filler port of the fuel tank 2, a dustproof oil guiding component 4 fixedly connected inside the fuel tank cap 3, a fixing frame 5 fixedly connected to one side of the body 1, a refueling component 6 slidably fitted on the fixing frame 5 to replace manual refueling, a fuel drum placement seat 7 mounted on the refueling component 6, and a fuel drum positioning component 8 provided on the fuel drum placement seat 7.

[0031] like Figure 3 As shown, the fuel tank cap 3 has a top opening structure. A sealing cap 301 is threadedly connected to the top opening of the fuel tank cap 3. An exhaust pipe 302 is fixedly connected through the inner wall of one side of the bottom end of the fuel tank cap 3. A movable block 303 is slidably fitted at the top opening of the exhaust pipe 302. T-shaped rods 304 are fixedly connected to both sides of the bottom end of the movable block 303. The T-shaped rods 304 are slidably fitted with the inner wall of the exhaust pipe 302. An alarm light is installed inside the fuel tank cap 3.

[0032] The exhaust pipe 302 is made of stainless steel, which is corrosion-resistant and high-temperature resistant. It is welded and fixed to the inner wall of the bottom of the fuel tank cap 3, ensuring a secure connection. Its bottom end extends to the upper part of the fuel tank 2, and its top end communicates with the inside of the fuel tank cap 3. During refueling, the air in the fuel tank 2 is compressed by the fuel and discharged through the exhaust pipe 302, preventing excessive air pressure in the fuel tank 2 from causing fuel spillage. At the same time, it balances the air pressure inside and outside the fuel tank 2, ensuring a smooth and uniform fuel injection. The warning light installed inside the fuel tank cap 3 uses an explosion-proof LED light, which is bright and energy-efficient. It is electrically connected to the liquid level sensor on the fuel guide pipe 401. The liquid level sensor monitors the fuel level in the fuel tank 2 in real time. When the fuel level reaches the preset maximum value, the liquid level sensor sends a signal to the warning light, which illuminates, reminding the staff to stop refueling in time to avoid fuel spillage, further improving refueling safety and preventing flammable and explosive hazards.

[0033] like Figure 4 As shown, the dustproof oil guiding assembly 4 includes an oil guiding pipe 401, which is fixedly connected to the inner wall of the bottom end of the oil tank cap 3. A liquid level sensor is installed at one end of the oil guiding pipe 401 inside the oil tank 2, and an elastic hose 402 is fixedly connected to the other end of the oil guiding pipe 401 inside the oil tank cap 3. A connecting ring 403 is fixedly connected to the other end of the elastic hose 402, and a connecting sleeve 404 is rotatably connected to the outer wall of the connecting ring 403. A placement ring 305 is fixedly connected to the inner wall of the bottom end of the oil tank cap 3. One end of the connecting sleeve 404 is in movable contact with the top of the placement ring 305, and the other end of the connecting sleeve 404 abuts against the sealing cap 301. The elastic hose 402 is stretchable, and the placement ring 305 facilitates the placement and retraction of the connecting sleeve 404.

[0034] The oil level sensor installed at one end of the oil guide pipe 401 inside the oil tank 2 is a waterproof and explosion-proof sensor with high detection accuracy. It can monitor the oil level in the oil tank 2 in real time and trigger an alarm light to detect the oil level. It also prevents backflow of oil when the bottom of the oil guide pipe 401 is submerged in fuel. The flexible hose 402 is made of high-temperature and oil-resistant silicone hose. It is soft, tough, and can be stretched and bent freely. Its length is adapted to the movement of the refueling component 6, ensuring that the connecting sleeve 404 is always tightly connected to the opening of the oil tank 702 when the tank is tilted, without disconnection or leakage.

[0035] like Figure 5As shown, a U-shaped opening 501 is provided on the fixed frame 5, and fixed racks 502 are fixedly connected to the inner walls on both sides of the U-shaped opening 501.

[0036] like Figure 6 As shown, the refueling component 6 includes a sliding frame 601. The outer wall of the sliding frame 601 is slidably fitted with the inner wall of the U-shaped opening 501. A threaded rod 602 is threadedly connected to the inner wall of the middle part of the sliding frame 601. The bottom end of the threaded rod 602 is rotatably connected to the fixed frame 5. A handle 603 is fixedly connected to the bottom end of the threaded rod 602.

[0037] The sliding frame 601 has two symmetrical sliding grooves 604 on both sides. A universal joint 605 is rotatably connected through the inner wall of the sliding groove 604. One end of the universal joint 605 extends through the inner wall of the sliding groove 604 to the outside and is fixedly connected to a drive wheel 606. The drive wheel 606 is engaged with a fixed rack 502 for transmission. A lead screw 607 is fixedly connected to the other end of the universal joint 605. The top end of the lead screw 607 is rotatably connected to the inner wall of the sliding groove 604. An adjusting block 608 is threadedly connected to the outer wall of the lead screw 607. The two sides of the adjusting block 608 are slidably engaged with the inner wall of the sliding groove 604. An adjusting rod 609 is rotatably connected to one side of the adjusting block 608. The other end of the adjusting rod 609 is rotatably connected to the oil drum placement seat 7.

[0038] The refueling component 6 is the core mechanism for automatically lifting and tilting the oil drum 702, replacing manual lifting and tilting, greatly reducing the intensity of operation and improving refueling efficiency and safety.

[0039] By setting up the refueling component 6, after fixing the oil drum 702 on the oil drum placement seat 7, the refueling component 6 can drive the oil drum 702 to move upward at a uniform speed while pouring, so as to automatically pour gasoline into the oil tank 2. There is no need for manual lifting and pouring, which greatly reduces the operation intensity and improves the refueling efficiency. The fuel pouring flow rate is uniform and controllable, effectively avoiding fuel spillage and waste and flammable and explosive safety hazards.

[0040] like Figure 7 As shown, one end of the oil drum placement seat 7 is rotatably connected to the top of the sliding frame 601. The oil drum placement seat 7 is provided with a positioning groove 701, and an oil drum 702 is placed in the positioning groove 701. The inner wall of the opening of the oil drum 702 is threadedly connected to the connecting sleeve 404.

[0041] The oil drum placement base 7 is made of high-strength steel, with a robust structure and strong load-bearing capacity, stably supporting the weight of the oil drum 702. One end of it is rotatably connected to the top of the sliding frame 601 via a pin, allowing for smooth and unimpeded rotation and flexible tilting to tip the oil drum 702. The positioning groove 701 is located at the top of the oil drum placement base 7, with an arc-shaped structure that precisely matches the outer wall of the oil drum 702, effectively positioning the oil drum 702 and preventing it from sliding or shifting on the placement base.

[0042] like Figure 8 As shown, the oil drum positioning assembly 8 includes a U-shaped frame 801, a limiting frame 802 is fixedly connected in the middle of the U-shaped frame 801, the limiting frame 802 is adapted to the handle of the oil drum 702, and the two sides of the limiting frame 802 are rotatably connected with a connecting rod group 803 in a centrally symmetrical structure.

[0043] The bottom end of the connecting rod assembly 803 is rotatably connected to the oil drum placement seat 7 via a pin. One end of the pin at the bottom end of the connecting rod assembly 803 is fixedly connected to a worm gear 804 inside the oil drum placement seat 7. A worm 805 is meshed and driven on one side of the worm gear 804. One end of the worm 805 is rotatably connected to the inner wall of the oil drum placement seat 7.

[0044] The self-locking function of the worm gear 805 and worm wheel 804 ensures that the position of the connecting rod assembly 803 is fixed after adjustment, without the need for an additional fixing mechanism. The structure is simple and the fixation is reliable.

[0045] Working principle: First, the operator rotates the handle 603 of the refueling component 6, causing the threaded rod 602 to rotate forward. The threaded rod 602 is threadedly connected to the sliding frame 601, causing the sliding frame 601 to move upward at a constant speed along the U-shaped opening 501 of the fixed frame 5. The sliding frame 601 causes the oil drum placement seat 7, the oil drum positioning component 8, and the oil drum 702 to move upward synchronously. At the same time, the transmission wheels 606 on both sides of the sliding frame 601 mesh with the fixed rack 502 on the inner wall of the U-shaped opening 501, causing the transmission wheels 606 to rotate, causing the universal joint 605 to rotate synchronously. The universal joint 605 causes the lead screw 607 to rotate, and the lead screw 607 is threadedly connected to the adjusting block 608, causing the adjusting block 608 to move upward along the slide groove 604. The adjusting block 608 causes the adjusting rod 609 to rotate, and the adjusting rod 609 pushes the oil drum placement seat 7 to rotate around the top of the sliding frame 601 to a horizontal position.

[0046] Then, rotate the knob of the worm 805 of the oil drum positioning assembly 8 to drive the worm 805 to rotate. The worm 805 drives the worm wheel 804 to rotate, and the worm wheel 804 drives the pin at the bottom of the connecting rod assembly 803 to rotate, thereby causing the connecting rod assembly 803 to unfold. The connecting rod assembly 803 drives the U-shaped frame 801 and the limiting frame 802 to move to the top. Then, place the oil drum 702 filled with gasoline into the positioning groove 701 of the oil drum placement seat 7. Then, rotate the worm 805 in the opposite direction to make the limiting frame 802 move down and lock the handle of the oil drum 702. With the help of the self-locking function of the worm wheel 804 and the worm 805, the angle of the connecting rod assembly 803 is fixed, thereby firmly fixing the oil drum 702 on the oil drum placement seat 7, preventing the oil drum 702 from sliding or falling off during lifting and tilting, and ensuring refueling safety.

[0047] Then unscrew the cap of oil drum 702, then unscrew the sealing cap 301 at the top of oil tank cap 3, remove the connecting sleeve 404 from the placement ring 305, stretch the elastic hose 402, align the connecting sleeve 404 of the dustproof oil guiding assembly 4 with the opening of oil drum 702, rotate the connecting sleeve 404 to make the connecting sleeve 404 threadedly connected to the opening of oil drum 702, ensuring a tight connection and no leakage.

[0048] Then, the threaded rod 602 continues to rotate, causing the sliding frame 601 to move the oil drum placement seat 7, the oil drum positioning component 8, and the oil drum 702 upwards synchronously. Simultaneously, under the action of the fixed rack 502, the adjusting rod 609 pushes the oil drum placement seat 7 to slowly tilt around the top of the sliding frame 601, achieving a uniform upward movement of the oil drum 702 while slowly tilting it. Under the action of gravity, the gasoline inside the drum 702 flows out from the opening, enters the connecting sleeve 404, flows through the elastic hose 402 into the oil guide pipe 401, and then is precisely injected into the oil tank 2 through the oil guide pipe 401, achieving automatic refueling. During the refueling process, the air inside the oil tank 2 is compressed by the fuel, pushing the movable block 303 at the top of the exhaust pipe 302 upwards. The air is discharged through the exhaust pipe 302, balancing the air pressure inside and outside the oil tank 2, ensuring a uniform and smooth fuel injection, and preventing fuel spillage. The T-shaped rods 304 on both sides of the movable block 303 act as guides, ensuring that the movable block 303 moves smoothly and does not deviate. Workers can control the lifting speed of the sliding frame 601 and the tilting angle of the oil drum 702 by adjusting the rotation speed of the throttle 603, thereby controlling the flow rate of the fuel pouring, ensuring a uniform and controllable flow rate, and improving refueling efficiency.

[0049] During refueling, a level sensor at one end of the oil guide pipe 401, located inside the oil tank 2, monitors the oil level in the tank 2 in real time and transmits the signal to the alarm light inside the tank cap 3. When the oil level in the tank 2 reaches the preset maximum value, the level sensor sends a trigger signal, illuminating the alarm light and triggering a buzzer alarm to remind staff to stop refueling immediately. Upon receiving the alarm, staff stop turning the handle 603, causing the sliding frame 601 and the oil drum 702 to stop rising, falling, and tilting. Then, they turn the handle 603 in the opposite direction, causing the threaded rod 602 to rotate in the opposite direction. The sliding frame 601 slowly moves downward, the oil drum placement seat 7 gradually returns to its original position, and the oil drum 702 stops tilting, completing the refueling operation.

[0050] After refueling, rotate the connecting sleeve 404 in the reverse direction to separate it from the opening of the oil drum 702. Then, place the connecting sleeve 404 on the placement ring 305 inside the oil tank cap 3, and the elastic hose 402 will naturally retract and reset. Next, rotate the knob of the worm gear 805 of the oil drum positioning assembly 8 to drive the worm gear 805 to rotate in the reverse direction. The worm wheel 804 drives the connecting rod assembly 803 to fold, and the U-shaped frame 801 and the limit frame 802 move upward, loosening the fixation on the oil drum 702. Remove the empty oil drum 702 from the oil drum placement seat 7 and store it properly. Then, tighten the sealing cap 301 at the top of the oil tank cap 3. The sealing cap 301 abuts against the connecting sleeve 404 to achieve a double seal, effectively preventing dust and debris from entering the oil tank cap 3 and the oil tank 2, thus playing a dustproof protection role. The movable block 303 of the exhaust pipe 302 resets under its own weight and the action of the T-shaped rod 304, sealing the exhaust pipe 302 and further improving the dustproof sealing effect.
