Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 7, comprise body 1, crankcase cover 2, water inlet pipe 3, oil sump 4, the first tube connectors 5, fine filter 6, exhaust outlet 7, admitting pipe joint 8, titting water outlet 9, exhaust heat exchanger 10, the second tube connectors 11, valve mechanism cover 12, cylinder head 13, valve 14, outlet pipe 15, temperature sensor 16, bent axle 17, internal rotor 18, external stator 19, external stator fixture 20, coolant duct 21, axle sleeve 22, nut 23, oil heat exchanger 24, boss 25, pipe connection 26, outlet 27, inlet tube 28, drainback passage 29 and blow vent 30 etc.
As Fig. 1～shown in Figure 3, the present invention includes engine and generator.This engine is the vertical shaft type engine, and being linked in sequence up and down by body 1, crankcase cover 2 and oil sump 4 forms.
As shown in Figure 4, engine interior is divided into two spaces up and down.Gear chamber is formed by body 1 and crankcase cover 2 in last space, and bent axle 17 is housed in the gear chamber, and bent axle 17 passes the downward space of gear chamber and stretches out.Accumulator is formed by crankcase cover 2 and oil sump 4 in following space, is provided with oil heat exchanger 24 in the accumulator.Generator is made up of internal rotor 18 and external stator 19.Generator is driven by bent axle 17 and produces electric current.Generator arrangements is in accumulator, and the internal rotor 18 of generator is connected the lower end of bent axle 17 by axle sleeve 22, and axle head is fixing with nut 23.External stator 19 is pressed in the external stator fixture 20.External stator fixture 20 is formed by aluminium alloy compression casting, and its inside is cast with coolant duct 21, and coolant duct 21 communicates with oil heat exchanger 24.
As Fig. 5, shown in Figure 6, the pipeline of coolant duct 21 and oil heat exchanger 24 is by being welded to connect on pipe connection 26, pipe connection 26 is equivalent to a pipe joint, two outlets are arranged, between two outlets by pipeline connection, the outlet welding of outlet and coolant duct 21, the inlet welding of another outlet and oil heat exchanger 24 cooling lines.In the present embodiment, between coolant duct 21 and oil heat exchanger 24 pipelines for connecting, but also can be parallel connection between them.The excircle of external stator fixture 20 is provided with 6 boss 25.External stator fixture 20 is fixed on the crankcase cover 2 by boss 25.Be furnished with drainback passage 29 on the periphery of crankcase cover 2 equably.The top of drainback passage 29 is provided with blow vent 30, to guarantee the air pressure balance in the oil sump 4.
As shown in Figure 1 and Figure 2, a side of body 1 is provided with cylinder head 13, is connected with valve mechanism cover 12 on the cylinder head 13.Blast pipe on the cylinder head 13 links to each other with exhaust heat exchanger 10.The exhaust outlet 7 of blast pipe stretches out from the below of exhaust heat exchanger 10.
Cooling line on coolant duct 21, oil heat exchanger 24 and the cylinder head 13 of exhaust heat exchanger 10 and external stator fixture 20 inside communicates.
The cooling pipe of waste heat recovery plant is linked in sequence by the cooling line of the cooling line of the coolant duct 21 of generator external stator fixture 20 inside, oil heat exchanger 24, exhaust heat exchanger 10 and the cooling line on the cylinder head 13 and forms.As shown in Figure 7, cold water enters water inlet pipe 3 by admitting pipe joint 8, and then enter the coolant duct 21 of external stator 19 by inlet tube 28, then enter the cooling line of oil heat exchanger 24, enter first tube connector 5 by outlet 27, enter the cooling line of exhaust heat exchanger 10 then, the cooling water that flows out from the cooling line of exhaust heat exchanger 10 enters cooling line on the cylinder head 13 by second tube connector 11, flows out from titting water outlet 9 by outlet pipe 15 then.
The outlet pipe 15 of cylinder head 4 is provided with temperature sensor 16 and valve 14.When temperature valve-off 14 when predefined temperature is following of cooling fluid, stop the circulation of cooling fluid, prevent that the temperature of cylinder is low.
Cooling fluid coolant duct 21 in the supply generator external stator fixture 20 when its temperature is low, after having cooled off generator fully, carry out heat exchange with oil heat exchanger 24 in the oil sump 4 and obtain effective heat, again by exhaust heat exchanger 10, again to by the cooling line cold gas cylinder head part that is arranged on the engine cylinder cap 13, recuperation of heat once more, its temperature raises more.
Lubricating oil pump is installed on interior crankcase cover 2 inwalls of accumulator, and the lubricating oil pump inner rotor shaft is installed on the camshaft, rotates together with camshaft.Lubricating oil pump sucks low-pressure cavity to the machine oil in the accumulator by the coarse filter inflow pipeline, push and be pressed into high pressure chest, coming the fine filter 6 that is installed in external engine filters once more, filter qualified machine oil and remove lubricated all parts that need lubricate, as casing wall in bent axle 17, camshaft, piston and the cylinder etc., machine oil pressure release after having lubricated is to the interior low-lying place of gear chamber, low-lying place all is provided with drainback passage 29, drainback passage 29 communicates with accumulator, has got back to accumulator again thereby store up at the machine oil at low-lying place.
Lubricating oil maximum oil position in the oil sump 4 does not contact with the internal rotor 18 of generator, thereby can avoid lubricating oil exceedingly to be stirred, and prevents phenomenons such as machine oil degenerates, and engine operation is undesired.Lubricating oil at the upper surface of getting back to the lubricating oil the oil sump from the special-purpose drainback passage 29 of crankcase cover 2, has therefore been realized the convection current of lubricating oil at the bent axle axial direction by the oil-feed oil circuit inspiration of lubricating oil pump from the oil sump lowest part.Because drainback passage 29 is arranged on the periphery of crankcase cover 2 equably, so lubricating oil can improve the heat exchanger effectiveness of oil heat exchanger 24 in the convection current on every side of oil heat exchanger 24.
