Fig. 1 is to shown in Figure 4; Specific embodiments for the invention linkage type foot pump; It comprises supporting base 16, strut 13, foot-driven lever 1, piston rod 3, piston assembly 17, cylinder barrel lid 5, cylinder barrel 6, cylinder barrel base 8, and strut 13 is fixed on the supporting base 16, and cylinder barrel lid 5 and cylinder barrel base 8 correspondences are fixed on the two ends of cylinder barrel 6; Check valve assembly 18 is installed on the cylinder barrel base 8; Piston assembly 17 is arranged in the cylinder barrel 6, and described piston rod 3 one ends pass cylinder barrel lid 5 and are fixedly connected with piston assembly 17, the other end pass through piston rod hinge 2 and foot-driven lever 1 head hinged; Foot-driven lever 1 is hinged on the strut 13 through strut hinge 10; Strut hinge 10 is provided with foot-operated Returnning spring 12; The afterbody of foot-driven lever 1 is connected with movable foot treadle 15 through foot-operated hinge 14; Cylinder barrel base 8 is hinged on the bottom of strut 13 through cylinder barrel hinge 7, is fixed with spring fixing rod 11 on the described strut 13, and foot-operated Returnning spring 12 1 ends that are arranged on the strut hinge 10 are positioned on the spring fixing rod 11; The other end is buckled on the foot-driven lever 1, and cylinder barrel 6 is the pivot point arc swing with cylinder barrel hinge 7 in piston rod 3 working procedure.Cylinder barrel lid 5 adopts thread seal to fix with cylinder barrel 6, is Spielpassung between piston rod 3 and the cylinder barrel lid 5, and the pilot hole of cylinder barrel lid 5 offers seal groove, and O-ring seals is installed on the seal groove, and O-ring seals guarantees that cylinder barrel lid 5 is sealed and matched with piston rod 3.
Described check valve assembly 18 comprises valve seat 21, the spherical valve core 22 with taper angle, the valve gap 20 that has one-way valve outlet 23; Spherical valve core 22 is arranged on the taper angle of valve seat 21; Valve gap 20 is fixed on the valve seat 21; Spherical valve core 22 spheres and 21 imports of taper angle fitted seal valve seat, valve seat 21 is provided with sealing gasket 19.Described cylinder barrel base 8 is made up of upper bed-plate that is fixed as one and lower bottom base; Lower bottom base is provided with import; Be fixed with inlet union 9 in this import, upper bed-plate is fixed on valve seat 21 on the lower bottom base through sealing gasket 19, and the import of valve seat 21 communicates with the import of lower bottom base; Described cylinder barrel lid 5 is provided with outlet, is fixed with outlet connection 4 in this outlet.
The invention is in practical application, and with piston diameter 75mm, stroke 90mm is an example; Cylinder barrel 6 lumps together with gray cast iron with cylinder barrel base 8 and processes; Piston assembly 17 main parts are the rubber pistons that adopt the oil resistant abrasive rubber to process, and being provided with a diameter above the rubber piston is that 27 mm, thickness are the round iron sheet of 1 mm, and being lined with a diameter below is that 73 mm thickness are the round iron sheet of 2.5 mm; The valve gap 20 of check valve assembly 18, valve seat 21 adopt engineering plastics to process; Employing is threaded, and spherical valve core 22 adopts the oil resistant abrasive rubber to process and required certain rigidity, and this part has played the non-return effect; Inlet union 9 adopts 1/4 " joint is connected generation water inlet portion, outlet connection 4 employings 1/4 with inlet pipeline " joint is connected with rising pipe.
To draw water is example, during original state, at first supporting base 16 is placed or is fixed on the smooth ground; Perhaps be fixed on other fixture, inlet union 9 is connected with inlet pipeline, and outlet connection 4 is connected with rising pipe; And the sealing of maintenance whole piece pipeline; At this moment, spherical valve core 22 spheres and 21 imports of taper angle fitted seal valve seat, piston assembly 17 is in the bottom of cylinder barrel 6 under foot-operated Returnning spring 12 effects.
When starting working; Pin puts in the movable foot treadle 15; Firmly scrunch downwards, movable foot treadle 15 passes to foot-driven lever 1 through foot-operated hinge 14, and making foot-driven lever 1 is the rotation of fulcrum clockwise direction with strut hinge 10; Move upward through piston rod hinge 2 drive piston rods 3 and piston assembly 17 simultaneously, piston rod 3 and piston assembly 17 are done the arc track motion with piston rod hinge 2 when moving upward.Because the pilot hole of cylinder barrel lid 5 has the forced guiding effect to piston rod 3 and piston assembly 17; Can make piston rod 3 and piston assembly 17 in cylinder barrel 6, do relative straight-line displacement; So cylinder barrel 6 is the pivot point arc swing with cylinder barrel hinge 7 under piston rod 3 and piston assembly 17 drives, and cylinder barrel 6 is remained on the same center line with piston rod 3 and piston assembly 17 all the time; This action is till piston assembly 17 and cylinder barrel lid 5 touch; Foot-operated Returnning spring 12 firmly scrunches energy storage in the process downwards, and the principle of drawing water coexists with existing technology mutually, and this no longer repeats, thus the action that completion is upwards drawn water.
In this process, through many connecting rods effect of integral body, guarantee the circular arc rotation of piston rod 3 and piston assembly 17 moving linearly and many fulcrums cylinder barrel 6 in, make that riding action is that straight line moves all the time.Improved the capacity for work and the working efficiency of piston rod 3 and piston assembly 17 greatly, the feasible active force of riding acts on the piston assembly 17 through the transfer of many fulcrums smoothly, and the space range of activity seldom in the whole motion process.
After accomplishing the action of upwards drawing water, pin release action power, at this moment; The spring force that foot-operated Returnning spring 12 stores begins to play a role; Making foot-driven lever 1 is that fulcrum counterclockwise rotates with strut hinge 10, moves downward through piston rod hinge 2 drive piston rods 3 and piston assembly 17 simultaneously, and piston rod 3 and piston assembly 17 are done the arc track motion with piston rod hinge 2 when moving downward; Because the pilot hole of cylinder barrel lid 5 has the forced guiding effect to piston rod 3 and piston assembly 17; Can make piston rod 3 and piston assembly 17 in cylinder barrel 6, do relative straight-line displacement, so cylinder barrel 6 is the pivot point arc swing with cylinder barrel hinge 7 under piston rod 3 and piston assembly 17 drives; Cylinder barrel 6 is remained on the same center line with piston rod 3 and piston assembly 17 all the time; This moves till piston assembly 17 and cylinder barrel 6 bottoms touch, thereby accomplishes an actuating length, is returned to original state.Work so repeatedly, can reach the purpose of drawing water.
The invention flexible operation, easy to use, inlet pipeline adopts 65mm caliber sebific duct, and 7.5 meters of dried up vertical heights scrunch the speed with 110 times/minute, and the 70s time can pump water in the water surface to the cylinder barrel 6; The speed that continues with 40-60 time/minute again scrunches, and rising pipe adopts the running water pipe of 15 millimeters of diameters, and vertically test on plane, the face of land relatively, and water level rises 0.26 meter each second, rises to 13 meters and needs 50 seconds approximately; Increase because lift raises, scrunches power, the speed that scrunches drops to per minute 30-40 time/minute gradually, continues to promote the lift difficulty more obviously.If the open horizontal positioned of external pipeline at outlet connection 4 places, then the speed of scrunching can reach 60 times/minute, has different flows according to the difference of the external pipeline at outlet connection 4 places.
