Embodiment
Core of the present invention is a kind of sunlight thermal-arrest that utilizes, and by automatically controlled respectively with the heat energy input device, low boiling working fluid in the heating equipment produces vapor pressure, pushes piston respectively, thereby realizes low level water is delivered to high-order helioplant.The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present invention.In Fig. 1, the running principle of device can be explained as follows step by step:
The present invention is a kind of device that utilizes solar energy to be embodied as user's continuous pumpage function.The internal cavities that the frame 28 of device is constituted is divided into two-part by dividing plate 26, and condenser, heater, piston, hydrops groove and low boiling working fluid are respectively placed on wherein.Device is in running, sunlight is collected through solar thermal collector 1, working medium in the heating heat collector, obtain high temperature heat, enter the low boiling working fluid 22 and 23 that heats in heater 10 and the heater 11 in hydrops groove 15 and the hydrops groove 16 through recycle pump 2 conveyings and through electrically-controlled valve 4 and electrically-controlled valve 5 adjusting timesharing, the hot working fluid after the heat release is sent back to again to heat in the solar thermal collector 1 again finishes circulation.
The concrete method of operation that device draws water is:
The first step, electrically-controlled valve 4 is closed, and electrically-controlled valve 5 is opened, this moment, the heating working medium of recycle pump 2 drivings entered in the heater 10 through electrically-controlled valve 5, low boiling working fluid 22 in the heating hydrops groove 15 produces the steam of High Temperature High Pressure, moves to dividing plate 26 directions thereby promote piston 17.Water storage cavity 24 interior water will be extruded this moment, and this moment, one-way valve 12 was closed, and water can only flow to head-tank 7 by condenser 9 and through one-way valve 3.In this process, because the effect of connecting rod 19 will promote piston 18 toward the direction away from dividing plate 26, to in water storage cavity 25, produce negative pressure, water is sucked the water storage cavity 25 through one-way valve 13 from low pool 14, and this moment, one-way valve 6 was closed, and prevented that upper water is inhaled into.Be extruded through condenser 9 and one-way valve 3 at the water of water storage cavity 24 and enter in the process in upper pond 7, because the effect of condenser 9, will be condensed into liquid to the low boiling working fluid of hydrops groove 16 original heating evaporations, drip back in the hydrops groove 16, make and produce low pressure in this cavity, thereby piston 18 is attracted to the direction away from dividing plate 26, play the effect of accelerating piston motion.In this process, electrically-controlled valve 21 is closed, and the pressure on hydrops groove 15 and 16 both sides is inequality.
Second step, when piston 17 is depressed into dividing plate 26 closest approaches in first step process, close electromagnetism 5 and open electrically-controlled valve 4, allow heating working medium enter in the heater 11, open electrically-controlled valve 21 simultaneously, the high pressure steam that produces when allowing heater 10 heating is rapidly by entering into condenser 9 residing cavitys connecting tube 20, when the respectively residing chamber pressure balance of condenser 9 and 8, close electrically-controlled valve 21 at once, at this moment heater 11 continues the low boiling working fluid 23 in the heating heat accumulation groove 16, produce the steam of High Temperature High Pressure, promote piston 18 and move to dividing plate 26 directions, at this moment, the water in the water storage cavity 25 will be extruded, this moment, one-way valve 13 was closed, and water can only flow to head-tank 7 by condenser 8 and through one-way valve 6.In this process, because the effect of connecting rod 19 will promote piston 17 toward the direction away from dividing plate 26, to in water storage cavity 24, produce negative pressure, water is sucked the water storage cavity 24 through one-way valve 12 from low pool 14, and this moment, one-way valve 3 was closed, and prevented that upper water is inhaled into.Be extruded through condenser 8 and one-way valve 6 at the water of water storage cavity 25 and enter in the process in upper pond 7, effect for condenser 8, will be condensed into liquid to the low boiling working fluid that was heated evaporation in the hydrops groove 15 originally, drip back in the hydrops groove 15, make and produce low pressure in this cavity, thereby piston 17 is attracted to the direction away from dividing plate 26, play the effect of accelerating piston motion.In this process, electrically-controlled valve 21 is closed, and the pressure on hydrops groove 15 and 16 both sides is inequality.
In above-mentioned two step processes, effect by electrically-controlled valve 4 and 5, the heat energy that utilizes solar thermal collector 1 to produce heats low boiling working fluid 22 and 23 respectively, produce the steam of High Temperature High Pressure, promote piston 17 and 18 respectively, and, realize water is evacuated to upper pond 7 from low pool 14 by one- way valve 12,6 and 13,3 Kai Heguan.In this process when piston 17 to dividing plate 26 during near the directions operation, the water in the water storage cavity 24 is pressed towards a high position, the high temperature low boiling working fluid steam when passing through condenser 9 simultaneously in its cavity of living in of condensation, making it condensation becomes liquid, drops in the hydrops groove 16.In carrying out next process, promptly when piston 18 to dividing plate 26 during near the directions operation, the water in the water storage cavity 25 is pressed towards a high position, the high temperature low boiling working fluid steam when passing through condenser 8 simultaneously in its residing cavity of condensation, making it condensation becomes liquid, drops in the hydrops groove 15.Alternately heating and cooling thus make device can be continuously the water of low level be evacuated to a high position.
Fig. 2 is the enforcement illustration that replaces piston 17 with scalable diaphragm 27.The effect of scalable diaphragm 27 is the same with the effect of piston 17.Other parts and Fig. 1 are identical, so the working principle of the working principle of Fig. 2 and Fig. 1 is identical.
Fig. 3 is the enforcement illustration of no pressure-equalizing pipe.Among Fig. 3, owing to there is not pressure-equalizing pipe, the working medium groove on both sides is not communicated with all the time, the heated initial period of one side low boiling working fluid therein, can not utilize the waste heat of another side, and only this item is different with Fig. 1, and other working procedure and Fig. 1 are identical.
