Shaft coupling output flange 241 is fixedly connected with the lift pump input shaft 24 of centrifugal lift pump 20, between the high speed output shaft 34 of planetary gearbox 30 being driven by hand recreation apparatus 55 and the lift pump input shaft 24 of centrifugal lift pump 20, adopt flange coupling 40 to pass through the transmission tube clearance hole 17 of divider wall 19, shaft coupling input flange 341 is fixedly connected with the high speed output shaft 34 of planetary gearbox 30, guarantees that operator can be in comfortable space to keep apart with outdoor machine equipment configuration severe environment of living in.

Fig. 1, Fig. 2, in Fig. 3 and Fig. 4, any climatope, by means of flange coupling 40, pass through effective isolation of the transmission tube clearance hole 17 of divider wall 19, in exercise, can indoorly be accompanied by music, can alone or two people one group, rotary handle 50 in the hand recreation apparatus 55 of slow rhythm motion rotation turning by per minute 30, through planetary gearbox 30, with per minute 900, turn by flange coupling 40 and drive centrifugal lift pump high speed rotating, from promoting water inlet pipe 21, draw the seawater filtering through seabed water strainer 11, being lifted out after the water pipe clearance hole 18 that water pipe 29 ecto-entads pass through divider wall 19 of centrifugal lift pump 20, receive successively micro-electrolytic cell treatment unit 13 and dirt slag sedimentation and filtration device 14, be sent in clean sea water slack tank 15 standby.

Simultaneously or stagger the time, other people's both feet step down in respectively on the footboard 84 of foot-operated recreation apparatus 70 of paired setting, when acting on left foot while pedaling under right crus of diaphragm, whole body weight mentions, the residing footboard 84 of right crus of diaphragm forces pedal lever 85 around lever pivot pin 95 bottoms, drive piston round bar 75 and pump piston 73 brute forces to move down, high pressure water is extruded from the high-pressure pump rising pipe 79 of pumping cylinder chamber base plate 77, be injected into the permeable membrane ante-chamber 91 of reverse osmosis membrane assembly 90; The strong brine bleed valve 97 that is positioned at permeable membrane ante-chamber 91 can be used for regularly emitting the strong brine being retained down of permeable membrane ante-chamber 91.

Meanwhile, be borrowed in the bounce of cylindrical spring 65, the residing footboard 84 of left foot and pedal lever 85 are around pendulum on lever pivot pin 95, drive on piston round bar 75 and pump piston 73 and move, produce the pre-treating seawater that negative pressure is drawn clean sea water slack tank 15 from the high-pressure pump water inlet pipe 71 of pumping cylinder chamber base plate 77.The bounce of cylindrical spring 65 is also prepared for next round presses down, and realizes the alternately acting of left and right bipod.

Pedal lever 85 interludes slide the elongated slot 86 lower end slide block 67 that is being slidably matched, between the piston pike pole 76 of piston round bar 75 lower ends and lower end slide block 67, there is slideway pivot pin 66 rotatable fixing, the rotation that said structure changes pedal lever 85 into lower end slide block 67 around the campaign of rotation up and down of lever pivot pin 95 and is moved up and down, and then with piston round bar 75, does upper and lower translational motion.Sliding the be slidably matched effect of lower end slide block 67 of elongated slot 86 has also eliminated the rotation that pedal lever 85 changes lower end slide block 67 into around the campaign of rotation up and down of lever pivot pin 95 and the little deviation moving up and down.

The foot-operated recreation apparatus 70 arranging in pairs, in conjunction with having this special setting of horizontal flange backstop 80 on the high-pressure pump water inlet pipe 71 of the Small Plunger Pump of every foot-operated recreation apparatus 70 and high-pressure pump rising pipe 79, guarantee that the discharge pressure of the pre-treating seawater pressure of 15 li of clean sea water slack tanks being brought up to 5 to 6 MPas (MPa) can not produce reverse counterflow, operational safety is reliable.

Miniature plunger discharge of pump is 8 liters per hour, and the discharge pressure of 5.5 MPas is connecting the permeable membrane ante-chamber 91 of reverse osmosis membrane assembly 90 through high-pressure pump rising pipe 79; Through reverse osmosis membrane assembly 90 forced filtrations, from permeable membrane back cavity 92 is out injected into 98 processing of activated carbon adsorption tank, be finally stored in fresh water hold-up vessel 99 stand-by again.Desalination water after 98 absorption of activated carbon adsorption tank meets < < drinking water sanitary standard > > GB5749-2006 standard.

In addition, on lifting water inlet pipe 21, configure flange backstop 10, can guarantee to promote water inlet pipe 21 and centrifugal lift pump 20 can retain water level when quitting work, next use can be exempted and the outdoor trouble that adds diversion, the key problem in technology that airtight ring cavity 166 is flange backstops 10 that forms between cavity sleeve 160 and moving valve core 170 will be arrived.
