Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] The present invention will be further explained below with reference to specific embodiments.

[0021] Please see Figures 1-10 This invention provides a fuel-detecting tractor unit, comprising: The frame 1 includes an engine assembly 2, a fuel tank assembly 3, and a drum assembly 4 mounted on the frame 1. The engine assembly 2 includes a generator, a transmission structure, and an engine cover. The fuel tank assembly 3 includes a fuel tank and a fuel tank bracket. The drum assembly 4 includes multiple traction wheels. The engine assembly 2, the fuel tank assembly 3, and the drum assembly 4 can all be constructed using existing publicly available technologies. A fuel detection mechanism for monitoring remaining fuel level is installed inside the fuel tank. The mechanism includes a metal rod 7 within the tank, on which a first float block 8 is slidably mounted. The first float block 8 has a locking detection component. The metal rod 7 is made of stainless steel and integrates a wire-wound resistor or potentiometer. It also serves as the sliding track for the first float block 8. The first float block 8 is made of an oil-resistant, lightweight material (such as plastic or rubber) and floats on the liquid surface, sliding along the metal rod 7 according to the liquid level. As the first float block 8 rises and falls with the liquid level, it moves the potentiometer slider inside the metal rod 7, changing the resistance value in the circuit. Different resistance values ​​correspond to different liquid level heights, which are ultimately converted into a fuel level display via a preset display instrument. Fuel level monitoring system used to assist fuel testing agencies in monitoring remaining fuel levels; And a protective mechanism for preventing the risk of slippage, which is mounted on the frame 1.

[0022] In an embodiment of the present invention, during operation, the traction machine utilizes a fuel level monitoring system to monitor fuel level information in real time via sensors. As the fuel level changes, the first float 8 slides along the metal rod 7. When the first float 8 rises and falls with the liquid level, it moves the potentiometer slider inside the metal rod 7, changing the resistance value in the circuit. Different resistance values ​​correspond to different liquid level heights, which are ultimately converted into fuel level display via a preset display instrument. By utilizing the locking detection component, a timely warning can be issued when the first float 8 gets stuck, preventing safety accidents. The protective mechanism, in conjunction with the drum assembly 4, effectively prevents slippage during traction, further improving the safety performance of the traction machine during operation. Compared to the prior art, the present invention, through the coordinated design of the fuel level monitoring system and the fuel detection mechanism, avoids the problems of existing traction machines, which mostly use fuel engines as power sources, but whose fuel level monitoring methods are relatively traditional. If the fuel float gets stuck, it is difficult to detect, affecting the accuracy of monitoring, and the monitoring method is singular. The protective mechanism avoids the problem that most existing traction machines lack safety protection structures, leading to slippage between the cable and the traction wheel, which can easily cause serious safety accidents.

[0023] In one embodiment of the present invention, please refer to Figures 1-10 The jamming detection component includes: A lifting rod 11 is slidably installed on the first floating block 8, and multiple sets of the lifting rod 11 are provided in the circumferential direction of the first floating block 8; Pressure sensor 12 is fixedly installed in the cavity of the first floating block 8, and the number of pressure sensors 12 is equal to the number of lifting rods 11. And a second floating block 10 fixed to the bottom of the lifting rod 11, wherein a baffle 13 for pressing the pressure sensor 12 is fixedly installed at the end of the lifting rod 11 away from the second floating block 10.

[0024] In this embodiment, the second floating block 10 is made of an oil-resistant lightweight material (such as plastic or rubber). When the first floating block 8 is always floating on the oil surface, the buoyancy of the second floating block 10 will push the lifting rod 11 upward, causing the baffle 13 to separate from the pressure sensor 12. When the first floating block 8 gets stuck, it will not slide on the metal rod 7. As the amount of oil decreases, the liquid level drops. At this time, after the second floating block 10 separates from the liquid surface, it will pull the lifting rod 11 downward under the action of gravity, causing the baffle 13 to contact the pressure sensor 12. This allows the pressure sensor 12 to detect the pressure, and the pressure sensor 12 will transmit the detected pressure information to the preset alarm module for early warning, effectively improving safety performance. The alarm module adopts existing publicly available technology and can set condition values ​​according to actual needs, that is, an early warning will only be issued after a certain number of pressure sensors 12 detect the pressure, effectively preventing false alarms.

[0025] In one embodiment of the present invention, the oil quantity monitoring system includes: The fuel level detection module is used to collect data on the fuel level, temperature, and density in the fuel tank. The central control module is electrically connected to the fuel quantity detection module and is used to receive and process the data collected by the fuel quantity detection module to calculate the real-time fuel quantity and remaining driving time. The linkage control module is electrically connected to the central control module and is used to adjust the operating parameters of the engine assembly 2 according to the fuel quantity signal output by the central control module. The remote monitoring module is communicatively connected to the central control module and is used to receive and store fuel quantity data and equipment operating status information to achieve remote monitoring. The display and warning module is electrically connected to the central control module and is used to display fuel quantity-related data and issue graded warning signals. The fuel quantity detection module includes a level sensor, a temperature sensor, and a density sensor. The level sensor is a capacitive level sensor installed at the bottom of the fuel tank to collect fuel level data. The temperature sensor and density sensor are integrated and installed in the middle of the fuel tank to simultaneously collect fuel temperature and density data.

[0026] The central control module includes a data processing unit and a storage unit. The data processing unit uses an ARM Cortex-M4 core processor to calculate the actual fuel mass and remaining driving range based on fuel level, temperature and density data using a preset algorithm. The storage unit is used to store historical fuel quantity data, calibration parameters and warning thresholds.

[0027] The linkage control module includes an engine speed regulation unit and a traction limiting unit; when the fuel level is lower than a first warning threshold, the engine speed regulation unit limits the maximum engine speed; when the fuel level is lower than a second warning threshold, the traction limiting unit reduces the maximum traction output, and the second warning threshold is less than the first warning threshold.

[0028] The remote monitoring module includes a data transmission unit and a cloud management platform. The data transmission unit uses a combination of CAN bus and 4G module to upload fuel quantity data, equipment operating parameters and early warning information to the cloud management platform in real time. The cloud management platform supports data storage, historical query, report generation and remote alarm push.

[0029] The display and warning module includes a touch screen and an audible and visual alarm; the touch screen is used to visually display real-time fuel level, remaining driving range, fuel temperature and historical consumption curve; the audible and visual alarm emits audible and visual signals of different frequencies according to the warning level, and supports manual alarm shutdown.

[0030] The preset algorithm includes a temperature compensation algorithm and a density correction algorithm; the temperature compensation algorithm is used to correct the measurement error of the liquid level sensor based on the fuel temperature; the density correction algorithm is used to calculate the fuel mass by combining the fuel density, with the formula: m=ρ×V, where m is the fuel mass, ρ is the fuel density, and V is the fuel volume.

[0031] In this embodiment, the fuel quantity detection module is the core of fuel quantity monitoring, enabling multi-dimensional data collection: The liquid level sensor is a capacitive sensor, installed at the bottom of the fuel tank, with a measurement range of 0-100% and a measurement accuracy of ±0.5%, which can collect the fuel level height in real time. The temperature sensor and density sensor are integrated and installed in the middle of the oil tank. The temperature measurement range is -40℃ to 85℃, and the density measurement range is 0.75-0.85 g / cm³. 3 Simultaneously collect fuel temperature and density data to provide a basis for correcting fuel quantity calculations; The central control module, as the "brain" of the traction machine, has high-speed data processing capabilities and its main functions include: When the fuel level is below the first warning threshold (the remaining fuel level is 30% of the total capacity), the maximum engine speed is limited to no more than 80% of the rated speed to reduce fuel consumption. When the fuel level is below the second warning threshold (remaining fuel level is 15% of the total capacity), the maximum traction force output is reduced to 60% of the rated traction force, and the operator is prompted to replenish the fuel as soon as possible. By combining a fuel level monitoring system with a fuel testing agency, accurate fuel level detection can be achieved, effectively preventing safety accidents.

[0032] In one embodiment of the present invention, please refer to Figures 1-10 The protective mechanism includes: The base 6 is provided on the frame 1, and a support platform is provided for mounting the base 6. The support frame 5 is slidably mounted on the base 6, and the base 6 is provided with a translation component for moving the support frame 5; wherein the support frame 5 has a U-shaped structure. The support shaft 18 is rotatably mounted on the support frame 5. A guide wheel 21 is fixedly mounted on the support shaft 18, and the guide wheel 21 is provided with multiple sets of real-time clamping modules for clamping the cable during the traction process. And a control component for adjusting the working status of the real-time clamping module.

[0033] The translation component includes a strip groove on the base 6, a slider 24 fixedly connected to the support frame 5 is slidably installed in the strip groove, and a threaded rod 14 is rotatably installed in the strip groove. The slider 24 has an internal threaded hole for threaded connection with the threaded rod 14. The base 6 is provided with a translation motor for driving the threaded rod 14 to rotate.

[0034] The real-time clamping module includes: A L-shaped hole is provided on the guide wheel 21, and a movable frame 26 is slidably installed in the L-shaped hole; Guide wheel 28 is rotatably mounted on one end of the movable frame 26, and a pressing wheel 29 is rotatably mounted on the other end of the movable frame 26; wherein the pressing wheel 29 may be made of rubber material, and can undergo a certain deformation when squeezed, thereby pressing the cable tightly; And a spring 9 for elastically supporting the movable frame 26 on one side of the guide wheel 28, the spring 9 being disposed inside the guide wheel 21.

[0035] The control component includes: A control cover 16 is sleeved on the support shaft 18, and the support frame 5 is also provided with a telescopic cylinder 17 for pushing the control cover 16 to move in the length direction of the support shaft 18. The boss 25 is used to press the guide wheel 28. The boss 25 is located inside the control cover 16 and has a semi-circular structure. Both ends of the boss 25 are provided with inclined surfaces, and the middle part of the boss 25 is a plane connected to the inclined surfaces. External toothed ring 15, which is fixedly mounted on control cover 16; And a rotary motor 22 is mounted on the support frame 5. A gear 23 that meshes with the external gear ring 15 is fixedly mounted on the output shaft of the rotary motor 22. The thickness of the gear 23 is greater than the thickness of the external gear ring 15, so that the external gear ring 15 can always mesh with the gear 23 as it moves with the control cover 16. The rotary motor 22 is designed with a brake assembly, which can achieve self-locking when the rotary motor 22 is stopped. The guide wheel 21 has a groove 27 for limiting the cable; The guide wheel 21 has a limit hole 20 on its side wall, and two limit holes 20 are symmetrically arranged on both sides of the guide wheel 21. The control cover 16 has a limit block 19 that is inserted into the limit hole 20 on its outer wall, and the number of limit blocks 19 is equal to the number of limit holes 20.

[0036] In this embodiment, the cable passes through the guide wheel 21 as shown in the attached figure. Figure 1 As shown by the arrow, the configuration can be customized according to actual needs. The key is to ensure the cable travels along the guide wheel 21 in a U-shaped trajectory. The rotary motor 22 drives the gear 23 to rotate, which in turn drives the control cover 16 via the external gear ring 15. This adjusts the working position of the boss 25, allowing it to move to the side where the cable and guide wheel 21 are in contact. After adjustment, the telescopic cylinder 17 pushes the control cover 16, causing the boss 25 to press against the guide wheel 28 above it. During traction, the cable will drive the guide wheel 21 to rotate (another configuration can be used where a separate motor drives the support shaft 18 to rotate, causing the guide wheel 21 to move). (Moving synchronously with the cable), the movable frame 26 will follow the guide wheel 21, so that the guide wheel 28 can contact the boss 25 (at this time, the limiting block 19 and the side of the guide wheel 21 are just in contact, which makes it easy for the control cover 16 to move further so that the limiting block 19 can be inserted into the limiting hole 20, without affecting the normal cooperation between the boss 25 and the guide wheel 28), and pass over the boss 25, so that the guide wheel 28 pushes the movable frame 26 to move, and then the movable frame 26 drives the pressing wheel 29 to press on the cable, so as to realize real-time pressing of the cable during the traction process and prevent slippage. When the guide wheel 28 separates from the boss 25, the spring 9 will push the movable frame 26 to reset. When an emergency stop is required, the telescopic cylinder 17 can continue to push the control cover 16 to move. The rotation of the guide wheel 21 allows the limit block 19 to be inserted into the limit hole 20, thereby stopping the guide wheel 21 and assisting in emergency stops, thus improving safety performance.

[0037] In summary, the working principle of this invention is as follows: During operation, the traction machine utilizes a fuel level monitoring system to monitor fuel level information in real time via sensors. As the fuel level changes, the first float 8 slides along the metal rod 7. As the first float 8 rises and falls with the liquid level, it moves the potentiometer slider inside the metal rod 7, changing the resistance value in the circuit. Different resistance values ​​correspond to different liquid level heights, which are ultimately converted into fuel level display via a preset display instrument. The locking detection component provides timely warnings when the first float 8 gets stuck, preventing safety accidents. The protective mechanism, in conjunction with the drum assembly 4, effectively prevents slippage during traction, further improving the safety performance of the traction machine. The specific working steps of the fuel level monitoring system, fuel detection mechanism, and protective mechanism are as follows: When the first float 8 remains floating on the oil surface, the buoyancy of the second float 10 will push the lifting rod 11 upward, causing the baffle 13 to separate from the pressure sensor 12. When the first float 8 becomes stuck, it will no longer slide on the metal rod 7. As the oil volume decreases, the liquid level drops. At this time, after the second float 10 separates from the liquid surface, it will pull the lifting rod 11 downward under the action of gravity, causing the baffle 13 to contact the pressure sensor 12. This allows the pressure sensor 12 to detect the pressure and transmit the detected pressure information to the preset alarm module for early warning, effectively improving safety performance. The condition value can be set according to actual needs, that is, an early warning will only be issued after a certain number of pressure sensors 12 detect the pressure, effectively preventing false alarms. The rotary motor 22 drives the gear 23 to rotate, which in turn drives the control cover 16 to rotate via the external gear ring 15. This adjusts the working position of the boss 25, allowing it to move to the side where the cable and guide wheel 21 are in contact. After adjustment, the telescopic cylinder 17 pushes the control cover 16 to move, allowing the boss 25 to press against the guide wheel 28 passing above it. During traction, the cable drives the guide wheel 21 to rotate (or a separate motor can drive the support shaft 18 to rotate, causing the guide wheel 21 to move synchronously with the cable). The moving frame 26 follows the guide wheel 21. The movement allows the guide wheel 28 to contact the boss 25 (at this time, the limit block 19 and the side of the guide wheel 21 are just in contact, which makes it easy for the control cover 16 to move further so that the limit block 19 can be inserted into the limit hole 20 without affecting the normal cooperation between the boss 25 and the guide wheel 28), and passes over the boss 25, thereby causing the guide wheel 28 to push the moving frame 26 to move, which in turn causes the moving frame 26 to drive the pressing wheel 29 to press on the cable, thereby achieving real-time pressing of the cable during the traction process to prevent slippage. When the guide wheel 28 separates from the boss 25, the spring 9 will push the moving frame 26 to reset. When an emergency stop is required due to an unexpected situation, the telescopic cylinder 17 can continue to push the control cover 16 to move. The rotation of the guide wheel 21 allows the limit block 19 to be inserted into the limit hole 20, thereby stopping the guide wheel 21 and assisting in emergency stopping.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
