Embodiment
Below in conjunction with description of drawings embodiment of the present invention.
As shown in Figure 1, the wind energy heating device of vertical shaft aerofoil profile blower fan according to the invention is provided with a vertical shaft aerofoil profile wind energy conversion system, and the vertical shaft 2 of this wind energy conversion system is realized being connected with the axle of centrifugal pump 5 through a driving mechanism with belt and belt pulley 3; This centrifugal pump 5 is arranged in a circulation loop of hydraulic oil: promptly said circulation loop is disposed with fuel tank 10, centrifugal pump 5, flowmeter 6, stop valve 7, first pressure gauge 8, first restricting orifice 9, second restricting orifice 9 and second pressure gauge 8, takes back fuel tank 10 again from second pressure gauge 8 and forms said circulation loop.It shown in the label 4 base (Fig. 4) of this wind energy conversion system.
Cooperation when the blade 1 of wind energy conversion system is arrived in wind, produces the lift (Fig. 3) of L1 and L2 referring to Fig. 1, Fig. 2 and shown in Figure 3, and the component of lift produces moment (for example being clockwise moment) to the center of circle, thereby drives vertical shaft 2 rotations that are positioned at the center of circle.
Through the transmission of belt and belt pulley 3, with the running torque of vertical shaft 2 pass to centrifugal pump 5 spool on.Because the radius of belt pulley is greater than the radius of the axle of centrifugal pump 5, therefore, the rotating speed of centrifugal pump 5 is to increase relatively.Through the rotation of centrifugal pump 5, hydraulic oil is sucked from fuel tank 10 stir in the pump chamber of this centrifugal pump 5 to produce heat, make hydraulic oil produce certain pressure simultaneously and discharge high pressure oil.
When hydraulic oil is transported to wherein any said restricting orifice 9, spray at a high speed via the tiny pipeline of a plurality of bores that distributes on this restricting orifice 9.That is to say that connect each pipeline that is provided with on the restricting orifice 9, its bore is less than the pipe diameter in restricting orifice 9 upper reaches and downstream.Because it is big that the caliber in restricting orifice 9 downstream becomes, make the flow velocity step-down of fluid, therefore, impact, collide, rub between the fluid of going out orifice plate at a high speed and the low speed oil in orifice plate outlet port, thus the generation heat.
In preferred embodiment shown in Figure 1, be provided with two restricting orifices 9 with above-mentioned functions.Because restricting orifice 9 plays the effect that increases load in whole system, thus through increasing the quantity of restricting orifice 9, can improve the load of whole system, thus improve the heat production of system.
In certain embodiments; The return line of a carry potential overflow valve can be set at centrifugal pump 5 places; Then too fast when the rotating speed of centrifugal pump 5 and oil liquid pressure that cause being discharged by pump is too high, when flow increases; Can pass through relief valve, a part of hydraulic oil that centrifugal pump 5 is discharged sends back to continuation stirring generation heat in the centrifugal pump 5.
The bypass line (see figure 4) of a carry potential overflow valve 11 can be set in above-mentioned two-stage restricting orifice 9 places parallel connection in further embodiments; When wind speed is lower than setting value, can not pass through the two-stage orifice plate for preventing that oil liquid pressure is too small, then can open relief valve 11 and control fluid and pass through, thereby these restricting orifices 9 are closed from bypass line, reach the adjusting purpose that reduces system loading.Perhaps, also can be the above-mentioned bypass line of parallel connection on second restricting orifice 9 only, control the unlatching of second restricting orifice 9 or close.
In other some embodiments; For speed that fluid had and pressure with each tiny pipeline output on second restricting orifice 9 further convert heat energy to; One container that confluxes can also further be set in the downstream of second restricting orifice 9; Make that in the container that confluxes, compiling concurrent giving birth to from different directions from the fluid of each tiny pipeline output collides, rubs, thereby continue to produce heat.
As shown in Figure 4, above-mentioned wind energy heating device can also be provided with heat exchanger 12, and the high-temperature oil liquid that will pass through heating is transported to heat exchanger 12, makes the water generation heat exchange action that flows through in fluid and the heat exchanger 12.Heat exchanger 12 can further be connected with water storage box 13 and between forms the circulation of supplying water, and high-temperature oil liquid heats these circulating waters in heat exchanger 12, after arriving uniform temperature, obtains producing or the domestic hot-water, outwards carries for people to use.For example; In various embodiment; Can fluid be led to heat exchanger from any one-level restricting orifice 9 (preferably second restricting orifice 9) circulation loop afterwards, perhaps can directly heat exchanger be arranged on any one-level restricting orifice 9 circulation loop afterwards (Fig. 4).
Can be as shown in Figure 1, fuel tank 10 is set directly in the circulation loop, make to flow back in the fuel tank 10 through the low temperature fluid after the heat exchange, in fuel tank 10 deposition, filter after, again with the above-mentioned identical form pyrogenicity that circulates.Also can be as shown in Figure 4, after enough fluid in order to circulation pyrogenicity is arranged in the circulation loop, break off the connection of fuel tank to the circulation loop oil transportation; At this moment, heat exchanger 12 is set at after the second level restricting orifice 9 simultaneously as heat-exchange device, the container that confluxes container and/or temporarily hold fluid and uses, and then can directly be drawn and get into next circulation by centrifugal pump 5 through the low temperature fluid after the heat exchange.In a wind energy heating device of the present invention, any one or several that can be provided with simultaneously in above-mentioned these example structure makes up, to improve the heat production efficient of whole system.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
