Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power machinery and power generation equipment, and particularly relates to an integrated multi-purpose generator. BACKGROUND

[0002] In the fields of agricultural production, emergency rescue, etc., multiple devices such as power generation, irrigation, and ventilation are often needed to be used simultaneously. The existing technologies mostly adopt the mode of "single power source driving single device" or "multiple power sources driving respectively", which has problems such as low efficiency and inconvenience in moving. For example, the "power take-off system generator" disclosed in Korean patent KR100973067B1 has the core of driving the generator to generate power through the power take-off of the engine, and can only realize the single power generation function. If other devices such as water pump and air blower need to be driven, an independent engine needs to be additionally configured, which leads to device redundancy and increased energy consumption. At the same time, the patent lacks precise positioning and working condition adaptation mechanism, and the power transmission of the power take-off and the generator relies on multiple gearboxes, so that the energy conversion links are many, the transmission efficiency is only about 75%-80%, and the engine output parameters cannot be automatically adjusted according to the load change, which is easy to cause overload shutdown or power waste.

[0003] In addition, the existing multiple executor driven devices mostly adopt linear arrangement mode, which occupies large space, and the device switching needs to manually disassemble the connecting parts, which is complicated to operate and usually takes more than 5 minutes. Moreover, most of the devices have no unified power supply and control module, and the laser ranging and control unit need to be externally connected to the power supply, which limits the applicability. Therefore, an integrated power generation driven device capable of realizing efficient linkage of multiple executors, automatic adaptation to working conditions, and strong portability is urgently needed.

[0019] 1.2 Operation flow S1. Installation configuration: the generator 12 is fixed on the installation chassis of the sliding chassis 11 by bolts, and the sliding chassis 11 is numbered as "01"; the control device 3 (with a 7-inch touch screen, model TC7062) inputs the execution machine type corresponding to the number "01" as "STC-15kW generator", and the control device 3 automatically associates the pre-stored parameters (generator rated load 12kW, adaptive prime mover 1 output power 12kW, speed 1500r / min); S2.

[0022] 2.2 Operation process S1. Installation configuration: fix the water pump on the sliding chassis 11 with number "02", input the corresponding execution machine type "ISG50-160 water pump" for number "02" through the control device 3; the control device 3 automatically associates and combines parameters (generator load 12 kW + water pump load 5.5 kW, total load 17.5 kW, adapt to prime mover 1 output power 18 kW, speed 1800 r / min); S2. Docking adjustment: control device 3 drives positioning motor 7 to rotate turntable 9 by 60°, so that generator 12 of sliding chassis 11 with number "01" is docked with prime mover 1; positioning pin 63 is inserted into positioning hole 15 with a depth of 20 mm, and laser ranging device 64 feeds back "positioning success"; S3. Workstation adjustment: control device 3 synchronously drives linear modules of sliding chassis 11 with numbers "01" and "02": "01" drives generator 12 to move 300 mm to the working position, and convex strip 161 of inner shaft 16 is clamped into inner circle groove 841 of the connecting gear; "02" drives the water pump to move 280 mm to the working position, and convex strip 161 of inner shaft 16 (diameter 28 mm, length 140 mm) of the water pump is clamped into inner circle groove 841 of the corresponding connecting gear; S4.

Workstation adjustment: the control device 3 drives the linear module of the No. "01" "02" "03" sliding chassis 11, and synchronously adjusts the three actuators to the working position: the generator 12 moves 300 mm, the blower moves 290 mm, and the speed reducer moves 270 mm, and the convex strips 161 of the inner shafts 16 of the three are all clamped into the inner circle grooves 841 of the corresponding connecting gears; the output shaft (diameter 50 mm) of the speed reducer is connected with the rescue breaker through the shaft coupling (adapted to the speed 290 r / min, torque 500 N・m); S4.

Working condition adjustment: the control device 3 monitors the input torque of the speed reducer (normal range 65-70 N·m) through the torque sensor (model TQ-500, measurement range 0-500 N·m, accuracy ±0.5%): when the breaker encounters hard rock (the input torque of the speed reducer rises to 77 N·m), the control device 3 immediately reduces the fuel injection amount of the prime mover 1, so that the output power is reduced to 25 kW, the speed is reduced to 1800 r / min (torque 132.7 N·m), and at the same time, the "overload warning" is issued through the sound and light alarm of the control device 3; when the breaker breaks through the obstacle (the torque decreases to 60 N·m), it automatically recovers to 28 kW output; during this period, the generator 12 continuously supplies power to the rescue lighting (10 pieces of 100 W LED lamps), communication equipment (walkie-talkie base station), and the air blower for ventilation of the rescue passage (can cover a space of 50 square meters, and the CO concentration is reduced to below 0.01%).
