Detailed Implementation

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] Example:

[0025] like Figs. 1 to 7As shown, a liquid lifting device includes an outer cylinder 1, a liquid storage tank 2, and a power assembly. A piston 3 is slidably connected to the inner cavity of the outer cylinder 1. The piston 3 is connected to the power assembly, which is in turn connected to the outer cylinder 1. An inlet pipe 11 and an outlet pipe 12 are provided on the outer cylinder 1. The outer cylinder 1 is connected to the inlet pipe 11 and the outlet pipe 12 via a one-way valve 4. The outer cylinder 1 is connected to the liquid storage tank 2 via the outlet pipe 12, which is located above the outer cylinder 1. One end of the inlet pipe 11 is connected to the one-way valve 4, and the other end is below the liquid surface for pumping water. The outlet pipe 12 is used to guide the liquid to the upper liquid storage tank 2.

[0026] The outer cylinder 1 has an opening at one end and a closed end at the other end. A one-way valve 4 is located at the closed end and is threadedly connected to the one-way valve 4 through a screw hole. A bearing 5 is located at the open end of the outer cylinder 1. A first rotating shaft 31 is located at one end of the piston 3. A groove is opened on the outer wall of the piston 3. A sealing ring 32 is located in the groove. The sealing ring 32 contacts the inner cavity of the outer cylinder 1. The piston 3 and the outer cylinder 1 cooperate to form a variable volume cavity.

[0027] The power assembly includes a crankshaft 6, a ratchet 7, and a float rod. The crankshaft 6 is rotatably connected to the outer cylinder 1 at both ends through bearings 5. The crankshaft 6 can rotate circumferentially. The crankshaft 6 is connected to the first rotating shaft 31 through the first connecting rod 8. The first connecting rod 8 is rotatably connected to the piston 3 through the first rotating shaft 31. The crankshaft 6 and the ratchet 7 are coaxially connected. The ratchet 7 can rotate together with the crankshaft 6. The ratchet 7 is rotatably connected to the float rod.

[0028] The outer cylinder 1 is provided with a second rotating shaft 13, which is rotatably connected to a pawl 9. A torsion spring is provided on the second rotating shaft 13, which keeps the pawl 9 in contact with the ratchet 7 under the action of the torsion spring, thus preventing the ratchet 7 from reversing.

[0029] The float rod includes a second connecting rod 10 and a float 101. One end of the second connecting rod 10 is rotatably connected to a ratchet 7, and the second connecting rod 10 can rotate coaxially around the crankshaft 6. The other end of the second connecting rod 10 is connected to the float 101. The float 101 is a hollow sphere that can float on the liquid surface. As the liquid surface fluctuates, the second connecting rod 10, via the pawl 9, actuates the ratchet 7 to rotate in one direction, thereby causing the crankshaft 6 to rotate.

[0030] A third rotating shaft 102 is provided on the second connecting rod 10. The third rotating shaft 102 is rotatably connected to the pawl 9. A torsion spring is provided on the third rotating shaft 102. Under the action of the torsion spring, the pawl 9 is kept in contact with the ratchet 7 to prevent the ratchet 7 from reversing. With the cooperation of the ratchet 7 and the two pawls 9, the crankshaft 6 can be made to rotate in only one direction.

[0031] The one-way valve 4 has a conical opening 41 at the bottom and a stop bar 42 at the top. A sealing element 43 is installed inside the one-way valve 4, and through holes 44 are provided on both sides of the stop bar 42. The sealing element 43 can be a rigid small ball, with a diameter larger than the inner diameter of the conical opening 41 and the through holes 44. The small ball can only move between the conical opening 41 and the stop bar 42. When liquid flows in from the conical opening 41, it pushes the small ball upwards through the one-way valve. When liquid flows in from the through holes 44 on the side of the stop bar 42, the small ball descends to the conical opening 41 under gravity, blocking the passage and preventing liquid from flowing through, thus achieving one-way flow. Two one-way valves 4 are installed on the outer cylinder 1, with opposite installation directions. Liquid from the one-way valve 4 at the inlet pipe 11 can only enter the outer cylinder 1 from the outside, while liquid from the one-way valve 4 at the outlet pipe 12 can only exit from the outer cylinder 1 from the inside.

[0032] The outer wall of the one-way valve 4 is provided with external threads for threaded connection between the one-way valve 4 and the outer cylinder 1.

[0033] Working principle:

[0034] The fluctuation of the liquid surface causes the float 101 to swing, which in turn causes the second link 10 to swing, thereby driving the pawl 9 to rotate the ratchet 7.

[0035] The ratchet 7 is fixedly connected to the crankshaft 6, which drives the crankshaft 6 to rotate. The crankshaft 6 drives the piston 3 to reciprocate through the first connecting rod 8.

[0036] When piston 3 reciprocates, the volume of the cavity composed of outer cylinder 1, piston 3, and one-way valve 4 changes periodically.

[0037] When piston 3 moves out of the cavity, the cavity volume increases and a negative pressure is formed inside. The one-way valve 4 connected to the liquid outlet pipe 12 closes and the one-way valve 4 connected to the liquid inlet pipe 11 opens. Relying on the negative pressure, liquid is drawn into the cavity from the liquid inlet pipe 11.

[0038] When piston 3 moves into the cavity, the cavity volume decreases and positive pressure is formed inside. The one-way valve 4 connected to the inlet pipe 11 closes, and the one-way valve 4 connected to the outlet pipe 12 opens. Liquid is squeezed out from the outlet pipe 12 and enters the upper storage tank 2.

[0039] The reciprocating motion of piston 3 achieves the action of liquid suction and discharge, lifting the liquid from the bottom to the upper liquid storage tank 2.
