Description

Technical Field

[0001] This invention relates to the field of power machinery and power generation equipment technology, specifically to an integrated multi-purpose generator. Background Technology

[0002] In fields such as agricultural production and emergency rescue, it is often necessary to use multiple devices simultaneously, such as power generation, irrigation, and ventilation. Existing technologies mostly adopt the mode of "single power source driving single device" or "multiple power sources driving separately," which has problems such as low efficiency and inconvenience in movement. For example, the "power take-off system generator" disclosed in Korean Patent KR100973067B1 is based on an engine power take-off to drive a generator to generate electricity, which can only achieve the single function of power generation. If other equipment such as water pumps and blowers need to be driven, an additional independent engine is required, resulting in equipment redundancy and increased energy consumption. At the same time, this patent lacks a precise positioning and working condition adaptation mechanism. The power transmission between the power take-off and the generator relies on multiple gearboxes, resulting in multiple energy conversion links and a transmission efficiency of only about 75%-80%. Moreover, it cannot automatically adjust the engine output parameters according to load changes, which can easily lead to overload shutdown or power waste.

[0003] Furthermore, existing multi-actuator drive devices mostly adopt a linear arrangement, occupying a large space. Switching between devices requires manual disassembly of connecting parts, making the operation complex and the switching time usually exceeding 5 minutes. Moreover, most devices lack a unified power supply and control module, and laser rangefinders, control units, etc., require external power supplies, limiting their applicability. Therefore, there is an urgent need for an integrated power generation drive device that can achieve efficient linkage of multiple actuators, automatically adapt to working conditions, and is highly portable. Summary of the Invention

[0004] To address the problems of existing multi-actuator driven devices, such as "limited single function, large energy loss, complex switching, poor adaptability to operating conditions, and insufficient portability," this invention provides an integrated multi-purpose generator. It includes: a prime mover, a control device, a positioning feedback component, a connection component, multiple actuators, and an assembly chassis. The prime mover is mounted at one end of the assembly chassis, and a turntable is mounted at the other end. Each actuator necessarily includes a generator. The actuator is circumferentially positioned on the turntable and is driven radially along the turntable by a linearly movable sliding chassis. Each actuator's shaft extends inwards and outwards. A male connector is fixed to the outward-extending end, and the inward-extending end is the inner shaft. The prime mover's output shaft is fixed to a female connector. The connecting assembly includes a multi-faceted column, connecting bearings, and a central gear. The number of sides of the multi-faceted column matches the number of actuators. Each side has a connecting bearing. The outer ring of the connecting bearing is fixed to the side of the multi-faceted column, and the inner ring of the bearing protrudes into the multi-faceted column and is fixed with the connecting gear. Both the connecting gear and the central gear are bevel gears. All connecting gears... The axes of the actuator and the prime mover are both on the same horizontal plane. The connecting gear has a through hole in the middle for the inner shaft to enter and exit, allowing the inner shaft to move axially along the through hole. An inner groove is provided around the outer circumference of the through hole, and a protrusion matching the inner groove is provided at the end of the inner shaft. The intermediate gear is located inside the multifaceted column, its axis perpendicular to the horizontal plane and meshing with all connecting gears. The angle between the axes of the intermediate gear and the connecting gears is 90°. Each connecting bearing of the multifaceted column corresponds to an actuator, and the inner shaft of each actuator meshes with the shaft of the corresponding connecting bearing. The lines are coaxial and the inner shaft passes through the through hole; the positioning feedback component is located on the outside of the turntable, and several positioning holes are evenly distributed circumferentially on the inner side of the outer ring of the turntable. The number of positioning holes is the same as the number of actuators, and the depth of the positioning holes is different. When an actuator docks with the prime mover, the positioning feedback component inserts into the positioning hole and feeds back the insertion depth to the control device; the control device and the prime mover are integrated into one structure, and the control device stores the optimal output parameters for the prime mover to drive a single or multiple actuator combinations; an adjustment motor that drives the turntable to rotate is provided on the outside of the turntable.

[0005] Furthermore, the actuator is driven by a sliding chassis and has two working positions: an idle position near the end of the multifaceted column and a working position far from the end of the multifaceted column. When the actuator is in the idle position, the convex strip disengages from the inner ring groove, and when it is in the working position, the convex strip engages with the inner ring groove.

[0006] Furthermore, the assembly chassis is trapezoidal, with its narrower end serving as the head, which is equipped with a traction hook. The bottom of the assembly chassis is equipped with moving rollers, which are universal wheels with brakes, capable of moving the entire device and locking it in place during operation.

[0007] Furthermore, in addition to the generator, the actuator also includes one or more of the following: a water pump, a blower, and a reducer; the output shaft of the positioning motor is fixed with a gear, and a gear ring that meshes with the gear is provided on the outer circumference of the turntable. The gear ring is coaxially fixed with the turntable, and the positioning motor drives the gear to rotate, thereby driving the turntable to rotate.

[0008] Furthermore, the positioning feedback component includes: a bracket, a sleeve, a positioning pin, a spring, and a laser ranging device. The laser ranging device is located on the top of the sleeve. The bracket is fixed to the assembly chassis and located outside the turntable. The sleeve is directly above a point on the circumference where the positioning hole is located. The upper part of the bracket is fixed to the sleeve. The positioning pin moves up and down inside the sleeve. The middle section of the positioning pin has an annular protrusion. The spring is located between the laser ranging device and the annular protrusion. The transmitting and receiving ends of the laser ranging device are located inside the spring, which can detect the distance to the top of the positioning pin, thereby detecting the depth of the positioning pin inserted into the positioning hole. The positioning hole and the mounting position, i.e., the sliding chassis, have a one-to-one correspondence. Therefore, the control device can determine the type of actuator docked with the prime mover based on the actuator type of the pre-input position.

[0009] Furthermore, when the prime mover docks with the actuator, the positioning hole into which the positioning pin is inserted is the matching hole position of the sliding chassis where the actuator is located. The control device has pre-stored the matching hole position and the matching information of the sliding chassis, thereby numbering the sliding chassis. After the user installs the actuator, he / she needs to enter the type of the actuator installed in each number. The control device determines the actuator driven by the prime mover based on the distance information fed back by the positioning feedback component, the corresponding number of the actuator, and the work position information of each actuator, and then adjusts the working condition of the prime mover. The data is determined by multiple experiments of the prime mover driving one or more actuators, and the data is stored in cloud storage or local storage.

[0010] Furthermore, the intermediate gear is set on the turntable inside the triangular prism. The axis of the intermediate gear and the connecting gear are at an angle of 90°, and the cone angle of both is 45°, so as to realize meshing transmission. When the intermediate gear rotates, it can drive all the connecting gears to rotate synchronously, with a transmission ratio of 1:1.

[0011] Furthermore, the assembly chassis is also equipped with a battery and a converter. The generator's output can be connected to the converter, which can convert the generator's electrical energy into charging energy for the battery. The power for the laser rangefinder and control device is provided by the battery.

[0012] Furthermore, the sliding chassis includes a mounting chassis and a linear module. The mounting chassis is used to mount the actuator, and the linear module is used to drive the mounting chassis to move linearly in the radial direction of the turntable. The linear motor of the linear module is intermittently embedded in a slot mounted on the bottom of a triangular prism. The number of slots is the same as the number of linear modules (three in total). The linear motor is powered by a drive battery mounted above the slot. The linear motor is equipped with a wireless module and is controlled by a control device through the wireless module. The drive battery can be charged by a rechargeable battery.

[0013] A method for driving the above-mentioned integrated multi-purpose generator includes the following steps:

[0014] S1. Installation and configuration: The control device pre-stores the pairing information of the sliding chassis and matching hole positions to realize the numbering of the sliding chassis. The user installs the actuators on each sliding chassis set circumferentially on the turntable, and inputs the actuator type corresponding to each sliding chassis number through the control device.

[0015] S2. Dating Adjustment: The control device drives the adjustment motor to rotate the turntable according to the pre-stored information and user instructions, rotating one of the actuators that needs to work to the docking position with the prime mover. At this time, the positioning pin is inserted into the matching hole of the sliding base where the actuator is located under the action of the spring force, so as to achieve positioning.

[0016] S3. Workstation Adjustment: The control device drives the linear module of the sliding chassis through the wireless module, which drives the actuator to move radially along the turntable, adjusting all the actuators that need to work to the working position, ensuring that the protrusion of the inner shaft of the actuator is engaged in the inner ring groove of the connecting gear, and the remaining actuators are adjusted to the idle position, and the protrusion is disengaged from the inner ring groove.

[0017] S4. Power Transmission: The control device controls the start of the prime mover. The output shaft of the prime mover drives the docked target actuator to rotate through the cooperation of the female and male connectors. The inner shaft of the actuator drives the corresponding connecting gear to rotate through the convex rib. The connecting gear drives the intermediate gear to rotate through the meshing of bevel gears with a cone angle of 45°. The intermediate gear further drives the other connecting gears to rotate synchronously. If the actuator corresponding to the other connecting gear is in the working position, it drives the inner shaft of the actuator to rotate.

[0018] S5. Operating Condition Adjustment: The control device retrieves parameters determined by the original manufacturer's experiments from local storage or cloud storage, and adjusts the operating conditions of the prime mover, including output power and torque, based on the distance information of the positioning feedback component, the type and combination of actuators, and the working status of each actuator, to achieve efficient linkage and drive of multiple actuators.

[0019] Advantages of the present invention

[0020] 1. High transmission efficiency: It adopts direct meshing of bevel gears (45° cone angle and 90° shaft angle), without additional energy conversion links, and the power transmission efficiency reaches over 92%, which is 15%-20% higher than the power take-off system of KR100973067B1;

[0021] 2. Multi-scenario adaptation: Supports arbitrary combination and driving of multiple actuators, and the sliding chassis enables quick switching of workstations. The adjustment motor drives the turntable for precise docking (positioning accuracy ±0.1mm), meeting the needs of multiple scenarios such as agriculture and rescue.

[0022] 3. Intelligent and precise control: The control device has a built-in experimental parameter library covering various actuator combinations. Parameters can be updated via cloud storage, and the prime mover output can be adjusted in real time (power adjustment range 5-30kW, torque adjustment range 30-150N・m) to avoid overload or underload and solve the problem of existing equipment "not being able to automatically adapt to working conditions".

[0023] 4. High portability and integration: The chassis adopts a trapezoidal structure (2.5m long × 1.2m wide × 0.8m high), the towing hook is compatible with agricultural tractors or pickup trucks, and the universal wheels with brakes have a load capacity of ≥500kg; it integrates a battery and converter, eliminating the need for an external power source and meeting the needs of outdoor operations.

[0047] 1.2 Operating Procedures

[0048] S1. Installation and Configuration: Fix the generator 12 to the mounting chassis of the sliding chassis 11 with bolts. The sliding chassis 11 is numbered "01". Input the actuator type corresponding to number "01" as "STC-15kW generator" through the control device 3 (with a 7-inch touch screen, model TC7062). The control device 3 will automatically associate the pre-stored parameters (generator rated load 12kW, adapted prime mover 1 output power 12kW, speed 1500r / min).

[0049] S2. Docking Adjustment: Control device 3 sends a command to adjustment motor 7 via wireless module (Bluetooth 5.0, model HC-08). Adjustment motor 7 drives turntable 9 (diameter 1.2m, thickness 30mm, Q235 steel) to rotate, so that the male connector 4 of generator 12 is coaxial with the female connector 2 of prime mover 1 (coaxiality ≤0.05mm). At this time, positioning pin 63 is inserted into positioning hole 15 (depth 20mm) on the outer ring of turntable 9 under the action of spring 65. Laser ranging device 64 emits laser to detect that the distance to the top of positioning pin 63 is 10mm and feeds the signal back to control device 3.

[0050] S3. Workstation Adjustment: The control device 3 drives the linear module of the sliding chassis 11, which in turn moves the generator 12 radially outward 300mm along the turntable 9 to the working position. The protrusions 161 (6 in total, 3mm high and 5mm wide) at the end of the inner shaft 16 (30mm in diameter, 150mm in length, 45# steel) of the generator 12 are engaged in the inner ring groove 841 of the corresponding connecting gear in the connecting assembly 8. The control device 3 receives the "positioning signal" of the linear module.

[0051] S4. Power Transmission: Control device 3 controls the start of prime mover 1 (starting current 100A, starting time 3s), and adjusts the fuel injection quantity through the ECU (model EDC17) of prime mover 1 to stabilize the output power of prime mover 1 at 12kW and the speed at 1500r / min; the output shaft (diameter 40mm) of prime mover 1 is connected to the peripheral groove 21 and the central groove 22 of female connector 2 and the peripheral protrusion 41 and the central protrusion 42 of male connector 4 (fitting clearance 0.1mm), which drives generator 12 to rotate, and generator 12 outputs 380V / 50Hz AC power;

[0052] S5. Operating Condition Adjustment: Control device 3 monitors the output current of generator 12 in real time (normal range 18-22A) via current sensor (model ACS712): when the current exceeds 22A, control device 3 automatically reduces the fuel injection quantity of prime mover 1, reducing the output power to 10kW and the speed to 1300r / min; when the current is below 18A, the fuel injection quantity is increased to 12kW; at the same time, the 380V AC power output by generator 12 is converted to 12V DC power by converter 14 to charge battery 5 (charging current 15A, charging voltage 13.8V), and the power for laser ranging device 64 and control device 3 is provided by battery 5 (voltage stabilized at 12±0.5V).

[0053] 1.3 Monitoring and Verification of Key Parameters

[0054] Power transmission efficiency: The torque output torque of prime mover 1 is 95.5 N·m and the input torque of generator 12 is 88 N·m, as detected by torque sensor 64 (model TQ-205, measurement range 0-200 N·m, accuracy ±0.5%). The transmission efficiency is 88 / 95.5 × 100% ≈ 92.1%.

[0055] Positioning accuracy: The laser rangefinder 64 repeatedly measures the depth of the positioning hole 15 10 times, and the deviation is ≤0.03mm; the rotational positioning deviation of the turntable 9 is ≤0.1mm as measured by a dial indicator.

[0056] Power supply stability: The output voltage fluctuation range of generator 12 is 380±5V, and the frequency fluctuation range is 50±0.5Hz, which meets the GB / T2820-2009 standard "Reciprocating internal combustion engine driven alternator". It can directly supply power to agricultural lighting and small water pumps.

[0057] Example 2, driving two actuators 10 (generator 12 + water pump) – agricultural irrigation scenario

[0058] 2.1 Equipment Configuration Additions / Changes

[0059] New water pump: ISG50-160 vertical centrifugal pump (rated flow rate 50m³ / h, rated head 32m, rated power 5.5kW, speed 2900r / min, shaft diameter 28mm).

[0060] New sliding chassis 11: No. "02", with the same specifications as No. "01" (linear module KK8610P-400A+ mounting chassis).

[0061] Positioning hole 15: A new positioning hole with a depth of 25mm has been added;

[0062] Prime mover 1: The 495Q diesel engine is retained, with the output power adjustment range extended to 12-18kW and the torque adjustment range to 76.4-95.5N・m.

[0063] 2.2 Operating Procedures

[0064] S1. Installation and Configuration: Fix the water pump to the sliding chassis 11 with the number "02", and input the actuator type corresponding to the number "02" as "ISG50-160 water pump" through the control device 3; the control device 3 automatically associates the combined parameters (generator load 12kW + water pump load 5.5kW, total load 17.5kW, output power of the prime mover 1 18kW, speed 1800r / min).

[0065] S2. Docking and Adjustment: The control device 3 drives the adjustment motor 7 to rotate the turntable 9 by 60°, so that the generator 12 of the sliding chassis 11 with the number "01" docks with the prime mover 1; the positioning pin 63 is inserted into the positioning hole 15 with a depth of 20mm, and the laser rangefinder 64 reports "positioning successful".

[0066] S3. Workstation Adjustment: Control device 3 synchronously drives the linear modules of sliding chassis 11 numbered "01" and "02": "01" drives generator 12 to move 300mm to the working position, and the protrusion 161 of inner shaft 16 engages with the inner ring groove 841 of the connecting gear; "02" drives water pump to move 280mm to the working position, and the protrusion 161 of inner shaft 16 (diameter 28mm, length 140mm) of water pump engages with the inner ring groove 841 of the corresponding connecting gear;

[0067] S4. Power Transmission: The prime mover 1 starts, with an output power of 18kW and a speed of 1800r / min (torque of 95.5N・m); the output shaft of the prime mover 1, through the connection of the female connector 2 and the male connector 4, drives the generator 12 to rotate; the inner shaft 16 of the generator 12 drives the corresponding connecting gear (bevel gear) to rotate, and the connecting gear drives the intermediate gear 82 to rotate through the meshing relationship of the cone angle of 45°, and the intermediate gear 82 synchronously drives the corresponding connecting gear of the water pump to rotate, and the water pump starts; the flow rate of the water pump is detected as 50m³ / h by the flow sensor (model LDG-50, measurement range 0-100m³ / h, accuracy ±1%), and the head is detected as 32m by the pressure sensor (model MPM480, measurement range 0-1MPa, accuracy ±0.25%).

[0068] S5. Operating Condition Adjustment: Control device 3 monitors the load of the two actuators in real time: when the water level at the pump inlet decreases (flow rate drops to 40m³ / h), the pump load power drops to 4kW, and control device 3 automatically adjusts the fuel injection quantity of prime mover 1 to reduce the output power to 16kW (speed 1600r / min, torque 95.5N・m); when irrigation ends, control device 3 drives the linear module of sliding chassis 11 with number "02" to move the pump to the idle position, the convex strip 161 disengages from the inner ring groove 841, and the output power of prime mover 1 drops to 12kW.

[0069] 2.3 Verification of Collaborative Work Effectiveness

[0070] Synchronization of multiple actuators: Generator 12 speed 1500r / min (reduced by pulley, prime mover 1800r / min → generator 1500r / min), water pump speed 2900r / min (increased by its own pulley, prime mover 1800r / min → water pump 2900r / min), the speed deviation between the two is ≤1% as measured by a tachometer;

[0071] Energy consumption optimization: When the prime mover 1 outputs 18kW, the fuel consumption rate is 230g / kW・h (measured by a fuel consumption meter), which is 8% lower than the combined fuel consumption of "generator working alone (12kW, fuel consumption 220g / kW・h) + water pump working alone (5.5kW, fuel consumption 250g / kW・h)" (12×220+5.5×250=4195g / h) (18×230=4140g / h).

[0072] Ease of operation: No manual disassembly is required when switching actuators; the control device 3 automatically completes the workstation adjustment, with a switching time of ≤20s.

Installation and Configuration: Fix the blower to sliding chassis 11 numbered "02" and the reducer to sliding chassis 11 numbered "03"; input the type of blower "4-72-11No.5A" for number "02" and the type of reducer "RV30" for number "03" through control device 3; associate the combined parameters of control device 3 (generator 12kW + blower 7.5kW + reducer 7kW, total load 26.5kW, output power of prime mover 1 28kW, speed 2000r / min);

[0085] S2. Docking and Adjustment: The control device 3 drives the adjustment motor 7 to rotate the turntable 9 by 90°, so that the generator 12 of the sliding chassis 11 with the number "01" docks with the prime mover 1; the positioning pin 63 is inserted into the positioning hole 15 with a depth of 20mm, and the laser rangefinder 64 reports "positioning successful".

[0086] S3. Workstation Adjustment: Control device 3 drives the linear modules of sliding chassis 11 numbered "01", "02", and "03" to simultaneously adjust the three actuators to their working positions: generator 12 moves 300mm, blower moves 290mm, and reducer moves 270mm. The protrusions 161 on the inner shafts 16 of all three actuators are engaged in the inner ring grooves 841 of the corresponding connecting gears. The output shaft (50mm in diameter) of the reducer is connected to a rescue and obstacle-breaking machine (compatible speed 290r / min, torque 500N・m) via a coupling.

[0087] S4. Power Transmission: The prime mover 1 starts, with an output power of 28kW and a speed of 2000r / min (torque 133.5N・m); the prime mover 1 drives the generator 12 to rotate, the inner shaft 16 of the generator 12 drives the connecting gear, the connecting gear drives the intermediate gear 82, and the intermediate gear 82 synchronously drives the connecting gears of the blower and the reducer to rotate: the blower starts (air volume 12000m³ / h, air pressure 2200Pa), and the reducer drives the obstacle breaker after a 10:1 reduction (breaking speed 0.5m³ / h).

[0088] S5. Operating Condition Adjustment: Control device 3 monitors the input torque of the reducer (normal range 65-70 N·m) through a torque sensor (model TQ-500, measurement range 0-500 N·m, accuracy ±0.5%). When the obstacle-breaking machine encounters hard rock (the reducer input torque rises to 77 N·m), control device 3 immediately reduces the fuel injection quantity of prime mover 1, reducing the output power to 25 kW and the speed to 1800 r / min (torque 132.7 N·m). At the same time, the audible and visual alarm of control device 3 issues an "overload warning". When the obstacle-breaking machine breaks through the obstacle (torque drops to 60 N·m), it automatically restores the output to 28 kW. During this period, generator 12 continuously supplies power to rescue lighting (10 100W LED lights) and communication equipment (walkie-talkie base station), and the blower ventilates the rescue passage (covering a 50㎡ space, reducing CO concentration to below 0.01%).

[0089] 3.3 Scene Adaptation Effect Verification

[0090] Multi-device collaboration: Enables integrated operations of "obstacle removal - ventilation - power supply";

[0091] Battery life: The 24V / 150Ah lithium battery pack can power the control device 3, laser rangefinder 64, and positioning motor 7 for ≥8 hours when the generator 12 is off.

[0092] Mobility: The final assembly chassis 13 is connected to the pickup truck via a towing hook. On muddy roads (soil moisture content 30%), the moving speed is ≥10km / h, the ground pressure of the casters is 0.05MPa, and there is no risk of getting stuck.

[0093] Supplementary Explanation

[0094] It should be noted that the moving mechanism, such as the moving rollers at the bottom of the assembly chassis 13, is not shown in the attached drawings, but this does not mean that such a structure does not exist. The integrated multi-purpose generator of the present invention can be directly towed by an electric vehicle, which facilitates rapid deployment in outdoor scenes. At the same time, the battery 5 on the assembly chassis 13 can directly power the towed electric vehicle, further improving the range and practicality of the equipment.

[0095] 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.
