AI Technical Summary
The existing fuel inlet pipe lacks a preheating mechanism, which means that gasoline needs to be heated for a long time before entering the pipe, and the preheating process consumes a lot of time.
A fuel tank oil circuit heating device was designed. The device is activated by a buoyancy component and a push-button switch. External air is drawn in through the air intake pipe and heated by a resistance wire. The air is preheated in the delivery pipe through the hose and heating sleeve. The heat is then transferred into the delivery pipe through a heat conduction pipe.
It enables rapid heating of the conveying pipe, saving heating time and improving overall efficiency. It also saves electricity by physically disconnecting the power supply in a timely manner.

Abstract
Description
Technical Field
[0001] This invention relates to the technical field of fuel tank heating devices, specifically a fuel tank heating device and heating method. Background Technology
[0002] Fuel tanks, whether used on aircraft or automobiles, are specialized containers for storing hydraulic oil or hydraulic fluid in hydraulic systems. Oil tanks can be classified as open or closed. They must have a sufficiently large capacity; the suction and return pipes should be inserted below the lowest liquid level to prevent cavitation and air bubbles from splashing during return; the distance between the suction and return pipes should be as large as possible, and a baffle should be installed between them; to maintain oil cleanliness, the tank should have a perimeter-sealed cover with an air filter; the bottom of the tank should be at least 150mm above the ground; and sufficient attention should be paid to the anti-corrosion treatment of the tank's inner surface.
[0003] Connected to the fuel injector and fuel inlet pipe, when the solenoid coil is energized, it generates suction, lifting the needle valve and opening the injection orifice. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection orifice, forming a mist that promotes complete combustion. Previously, diesel engines used mechanically controlled fuel injectors. Mechanical diesel injectors operated by controlling precision components (needle valve and needle valve body).
[0004] The existing fuel inlet pipe does not use a preheating mechanism. When gasoline enters the fuel pipe, it needs to be heated by the heated gasoline, which consumes a lot of time during the preheating process, resulting in a technical problem of excessively long preheating time. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a fuel tank fuel circuit heating device and heating method, which solves the technical problem that existing fuel inlet pipes do not employ a preheating mechanism. When gasoline enters the fuel pipe, it is necessary to heat the fuel inlet pipe with preheated gasoline, which consumes a lot of time during the preheating process, resulting in excessively long preheating time.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a fuel tank oil circuit heating device and heating method, comprising a liquid collection plate, a delivery pipe, and a fuel injector, wherein the delivery pipe is fixedly installed on the side of the liquid collection plate, the fuel injector is threadedly installed on the bottom of the liquid collection plate, and a heating mechanism is sleeved on the outer wall of the delivery pipe;
[0009] The heating mechanism includes a connector, a buoyancy component, a connecting box, a battery box, an air inlet pipe, an injection pipe, and a heating sleeve. The heating sleeve is fitted onto the outer wall of the delivery pipe. The injection pipe is fixedly installed on the top of the heating sleeve. A connector is threaded onto one side of the delivery pipe. The buoyancy component is fixedly installed inside the connector. The connecting box is threaded onto the top of the buoyancy component. The battery box is snapped onto the back of the connecting box. The air inlet pipe is fixedly installed on the top of the connecting box. A flexible hose is fixedly installed on one side of the connecting box. The bottom of the flexible hose is threadedly connected to the inside of the injection pipe. The battery box includes a push-button switch, wires, a fan, and a resistance wire. The push-button switch is movably installed on the bottom of the battery box. Wires are fixedly installed on both sides of the battery box. Resistance wires are fixedly connected at the intervals between the wires. The fan is fixedly installed on the top of the side of the battery box. A heat-conducting pipe is fixedly installed inside the heating sleeve. A flow cavity is formed at the top of the heat-conducting pipe. An exhaust pipe is fixedly installed at the bottom of the heating sleeve.
[0010] Preferably, the buoyancy assembly includes a sealing ring a, a movable rod, a buoyancy ball, a sealing ring b, and a stop block. The movable rod is movably installed inside the buoyancy assembly. The buoyancy ball is fixedly installed at the bottom of the movable rod. The sealing ring b is fixedly installed at the top of the buoyancy assembly. The stop block is fixedly installed at the top of the movable rod.
[0011] Preferably, a connecting sleeve is fixedly installed at the bottom of the connecting box, a piston plate is movably sleeved inside the connecting sleeve, an extension rod is fixedly installed at the top of the piston plate, a spring is movably sleeved on the outer wall of the extension rod, and a connecting block is fixedly installed at the top of the extension rod.
[0012] Preferably, a threaded tube is fixedly installed on the side of the connector, and the outer wall of the threaded tube is threadedly connected to the inside of the delivery tube.
[0013] Preferably, the connector has a bearing cavity inside, and the inside of the bearing cavity and the outer wall of the buoyancy ball are nested together.
[0014] Preferably, the top of the connecting block and the bottom of the push switch are fitted together, and the top circumference of the connecting sleeve and the outer circumference of the push switch are fixedly connected.
[0015] Preferably, the connector box has a bearing cavity inside, and the battery box, wires, fan, and resistance wire are all located inside the bearing cavity.
[0016] Preferably, in step S1, the installation process involves: attaching the heating sleeve to the outer wall of the delivery pipe, then threading the inner wall of the connecting sleeve fixedly connected to the bottom of the connecting box to the outer wall of the buoyancy component, and then threading the threaded pipe fixedly installed on the side of the connector to the inner thread of the delivery pipe, so that the outer wall of the hose can be interlocked with the inner wall of the injection pipe.
[0017] S2. Working steps: As gasoline moves inside the delivery pipe, it first passes through the inside of the connector. During this process, the buoyancy of the buoyant ball will lift the moving rod, causing the stop block to push the piston plate upward. This will trigger the button switch, allowing the battery box to work normally. During operation, the resistance wire will generate heat, and the fan will blow air. The air will be heated as it passes through the outer wall of the resistance wire and then directly delivered into the inside of the hose. From there, it will be delivered into the inside of the injection pipe, and then into the inside of the heating sleeve. The heating sleeve can preheat the delivery pipe.
[0018] S3. Ending Steps: When the work is completed, rotate the connecting box to detach it from the outside of the buoyancy component. Then, rotate the air inlet pipe out from the inside of the hose and then detach it from the inside of the delivery pipe through the connector. At this point, the heating sleeve can be removed horizontally from the outer wall of the delivery pipe.
[0019] (III) Beneficial Effects
[0020] This invention provides a fuel tank oil circuit heating device and heating method. Compared with the prior art, it has the following advantages:
[0021] 1. This oil tank oil circuit heating device and heating method, through the heating mechanism, enables the buoyancy component to activate the push switch, and uses the air intake pipe to absorb external air into the interior of the connection box. When the air enters the connection box, it is heated by the resistance wire, and then transported into the interior of the hose, and then transported into the interior of the heating sleeve through the injection pipe. During the movement of the airflow in the flow cavity, it will introduce heat into the interior of the heat conduction pipe, and the heat conduction pipe will then introduce heat into the interior of the delivery pipe, which can heat the delivery pipe, save heating time and improve overall efficiency.
[0022] 2. The oil tank oil circuit heating device and heating method, through the connecting sleeve, utilizes the fact that the gasoline inside the connector will stop flowing, causing the supporting force to disappear, which will cause the extension rod to reset. During the reset process, the piston plate will be pushed back to its original position, causing the connecting block to stop pressing the switch, thereby enabling timely disconnection and saving power.
[0023] 3. This fuel tank oil circuit heating device and heating method utilizes a buoyancy component. The buoyancy causes a buoyant ball to push a movable rod upward. During this movement, a stop block fixedly installed at the top of the movable rod moves upward. The piston plate is pushed upward by the stop block, causing the extension rod to push the connecting block upward. Simultaneously, the spring movably sleeved on the outer wall of the piston plate is compressed. As the connecting block extends upward, it contacts the inside of the push switch. This contact closes the circuit, allowing the battery box to be started physically, thus saving time and improving overall efficiency. Attached Figure Description

Detailed Implementation
[0033] The technical solutions in the embodiments of the present invention have been clearly and completely described. 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.
[0034] Please see Figure 1-8This invention provides a technical solution: a fuel tank fuel circuit heating device and heating method, including a collection plate 1, a delivery pipe 2, and a fuel injector 3. The delivery pipe 2 is fixedly installed on the side of the collection plate 1, and the fuel injector 3 is threadedly installed on the bottom of the collection plate 1. A heating mechanism is sleeved on the outer wall of the delivery pipe 2. The heating mechanism includes a connector 5, a buoyancy component 6, a connecting box 8, a battery box 9, an air inlet pipe 10, an injection pipe 12, and a heating sleeve 4. The heating sleeve 4 is sleeved on the outer wall of the delivery pipe 2, and the injection pipe 12 is fixedly installed on the top of the heating sleeve 4. The connector 5 is threaded on one side of the delivery pipe 2, the buoyancy component 6 is fixedly installed inside the connector 5, the connecting box 8 is threaded on the top of the buoyancy component 6, the battery box 9 is snapped onto the back of the connecting box 8, the air inlet pipe 10 is fixedly installed on the top of the connecting box 8, and a flexible hose 11 is fixedly installed on one side of the connecting box 8. The internal threaded connection between the part and the injection pipe 12; the internal components of the battery box 9 include a push switch 901, wires 902, a fan 903, and a resistance wire 904. The push switch 901 is movably installed at the bottom of the battery box 9. Wires 902 are fixedly installed on both sides of the battery box 9. Resistance wires 904 are fixedly connected at the intervals between the wires 902. The fan 903 is fixedly installed on the top side of the battery box 9. The internal components of the heating sleeve 4 include a heat-conducting pipe 403. A flow cavity 402 is opened at the top of the heat-conducting pipe 403. An exhaust pipe 401 is fixedly installed at the bottom of the heating sleeve 4. A connecting sleeve 13 is fixedly installed at the bottom of the connecting box 8. A piston plate 14 is movably sleeved inside the connecting sleeve 13. An extension rod 15 is fixedly installed at the top of the piston plate 14. A spring 16 is movably sleeved on the outer wall of the extension rod 15. A connecting block 17 is fixedly installed at the top of the extension rod 15.
[0035] In a specific implementation, when the heating mechanism is required during operation, the heating sleeve 4 is first fitted onto the outer wall of the delivery pipe 2. Then, the outer wall of the connector 5 is threadedly connected to the inner wall of the delivery pipe 2. Next, the inner wall of the connecting sleeve 13 at the bottom of the connecting box 8 is threadedly connected to the outer wall of the buoyancy component 6. This allows the abutment 608 to fit snugly against the bottom of the piston plate 14. Then, the bottom of the hose 11 is threadedly connected to the inner wall of the injection pipe 12. When gasoline flows into the delivery pipe 2, it immediately enters the connector 5. Through buoyancy, the buoyancy component 6 activates the press switch 901, drawing in external air through the air intake pipe 10. The air then enters the connecting box 8. The gas is heated inside the box 8 by the resistance wire 904, and then delivered into the hose 11. It is then delivered into the heating sleeve 4 by the injection pipe 12. During the flow of the gas in the flow chamber 402, the gas will be introduced into the heat conduction pipe 403. The heat conduction pipe 403 will then be introduced into the delivery pipe 2, which can heat the delivery pipe 2. After that, the gas will be discharged from the exhaust pipe 401. When the operation stops, the gasoline inside the connector 5 will stop flowing, causing the supporting force to disappear. This will cause the extension rod 15 to reset. During the reset process, the piston plate 14 will be pushed back to its original position, causing the connecting block 17 to stop pressing the switch 901, so that it can be disconnected in time and save power.
[0036] Specifically, the buoyancy assembly 6 includes a sealing ring a601, a movable rod 602, a buoyancy ball 603, a sealing ring b607, and a stop block 608. The movable rod 602 is movably installed inside the buoyancy assembly 6. The buoyancy ball 603 is fixedly installed at the bottom of the movable rod 602. The sealing ring b607 is fixedly installed at the top of the buoyancy assembly 6. The stop block 608 is fixedly installed at the top of the movable rod 602.
[0037] In a specific implementation, when gasoline comes into contact with the buoyancy ball 603, the buoyancy will cause the buoyancy ball 603 to push the movable rod 602 upward. During the movement, the stop block 608 fixedly installed on the top of the movable rod 602 will move upward. During the movement, the piston plate 14 will be pushed upward by the stop block 608. During the movement, the extension rod 15 will push the connecting block 17 upward. At the same time, the spring 16 movably sleeved on the outer wall of the piston plate 14 will also be squeezed. During the upward extension, the connecting block 17 will come into contact with the inside of the push switch 901. During the contact, the circuit can be closed. At this time, the wire 902 will heat the resistance wire 904, and the fan 903 will rotate.
[0038] Specifically, a threaded tube 501 is fixedly installed on the side of the connector 5, and the outer wall of the threaded tube 501 is connected to the inner thread of the delivery tube 2.
[0039] In a specific implementation, the threaded pipe 501 fixedly installed on the side of the connector 5 allows the connector 5 to be easily removed and installed from the side, facilitating subsequent cleaning.
