In one embodiment, the dynamic pump tool mechanism further comprises a second fluid supply means selectively arranged to pump fluid from within the first piston pipe above the first piston to the first supply pipe, and the method further comprising the steps of: h) subsequent to step f), operating the second fluid supply means to pump fluid from within the first piston pipe above the first piston to the upper end of the first supply pipe.

The mechanism comprises and/or consists of pump tool and upwardly inner pipes. In addition, the pump tool includes three or more of upwardly extending inner pipe each inner pipe include a piston. The pistons are connected together by a pivot and crank assembly in a lower portion of the plurality of inner pipes. This is so that when one of the pistons is at or near the top of one of these pipes, the other pistons are near the bottom of the other inner pipes.

First and second inner pipes 20, 30 extend upwardly. The radius of the first upwardly extending inner pipe 20 is larger than the radius of the second upwardly extending inner pipe 30.

An upper target fluid tank 10 and means for positioning of the first and second upwardly extending inner pipes 20, 30 sealingly within the pump tool in which said pair of upwardly extending inner pipes adjacent is provided. By way of a general summary, the weight of the fluid in one of said upwardly extending inner pipes will cause the piston in the respective inner pipe fluidly connected thereto to move downwardly and the piston in the other of said upper extending inner pipes to move upwardly to force the water in the upwardly extending inner pipe into the upwardly extending inner pipe with a smaller diameter to the highest point, i.e. the upper fluid tank 10.

The invention will now be described in connection with the accompanying drawings wherein like reference numerals have been used to indicate like parts.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which: Figure 1 is a schematic illustration of the pump tool system, including a pump tool, a number of upwardly-extending inner pipes, a tank, a filling fluid tank, a plurality of valves, and an electrical fluid pump; and Figure 2 is a schematic illustration of a pump tool and the positioning of the respective pistons.

In the present invention, fluid can be lifted with a minimum amount of power. Figure 2 shows a dynamic pump tool 100. This dynamic pump tool 100 consist of three or more of upwardly-extending inner pipes 50,51,51n, where n can be any suitable specific number 1,2,...,n.

Each inner pipe contains a piston 52,53,53n, The pistons 52,53,53n are connected together to a pivot and crank assembly 59 located in the lower portion of the inner pipes 50,51,51n. The piston 52 is arranged on the pivot and crank assembly 59 to oppose the pistons 53, 53n. Therefore, if the piston 52 is in the lower portion of the inner pipe 50, the pistons 53,53n are located the upper portion of the inner pipes 51,51n and vice versa, The pump tool 100 comprising the inner pipes 50,51,51n is joined to the two pipes 20,30 as shown in Figure 1.

Figure 1 show the two upwardly inner pipes 20,30. The inner pipe 20 has a diameter larger than the inner pipe 30. Therefore, the volume of fluid that can be carried in pipe 20 is larger than the volume of fluid in pipe 30. The inner pipe 20 has a motorised valve 22 located and arranged at the bottom of the inner pipe 20. Further, an electrical pump 24 is located in communication with the inner pipe 20. The electrical pump 24 is used to draw the fluid from the top of the piston 52 in the inner pipe 50 to the top of inner pipe 20 through the feed inner pipe 26. The lower end of the feed inner pipe 26, which is inside the inner pipe 50 on the top of piston 52, is formed from resilient rubber so that it is not damaged by movement of the piston 52 up or down.

Also, in Figure 1, the inner pipe 30 comprises two branches at a lower end, each branch extending into the inner pipe 51,51n. The inner pipe 30 has, between the lower end of each branch and the respective inner pipe 51, 51n, a damper or non-return valve. This non-return valve is used to allow the fluid to enter upwardly into the base of the branches of the inner pipe 30 from the below (i.e. from the inner pipes 51, 51n) but to prevent the fluid from flowing back down into the inner pipes 51, 51n.

The inner pipe 30 reduces in diameter towards the upper end thereof, and has an upper end located in the tank 10. Tank 40 is used to fill inner pipe 51,51n with fluid through the motorised valve 44 from the pipe 42 with an electrical pump 46.

The operation of the system shown in Figure 1 will now be described.

Assuming that reservoir tank 40 is filled with fluid and the motorised valve 44 is closed.

The inner pipe 20 is filled with fluid and the motorised valve 22 is closed. Further, there is no fluid in the dynamic pump pipes 50,51,51n.

The first step is to open the valve 44 and operate the pump 46 at the same time. This causes the fluid to enter the inner pipes Si, 51n. The pressure of the fluid acts on the top of the pistons 53,53n within the respective inner pipe 51,51n, resulting in the piston(s) 53,53n moving to the lowest position within the inner pipes Si, 51n (i.e. furthest from the top). Due to the connection of the pistons 52, 53, 53n through the pivot and crank assembly 59, the piston 52 will also move to an uppermost position. Then, the valve 44 can be closed and the pump 46 turned off. These two actions are performed together in one embodiment, i.e. substantially simultaneously.

The second step is to open valve 22 at the base of the inner pipe 20. The weight of the fluid within the inner pipe 20 is larger than the weight of the fluid in the pipe 30 because the volume of fluid within the inner pipe 20 is larger than the volume of fluid can in the inner pipe 30 due to the increased diameter of the inner pipe 20, Therefore, the piston 52 will be pushed down by the pressure of the fluid in the inner pipe 20. Concomitantly, the piston(s) 53,53n will move upward, carrying the fluid located within pipes Si, 51n through the inner pipe 30 to the target tank 10.

In the third step, the valve 22 is closed fully.

In the fourth step, the pump 24 is operated to draw fluid from the top of the piston 52 in the inner pipe 50 to carry this fluid to the top of the inner pipe 20 through pipe 26. At the same time the operations of the first step are repeated, i.e. the valve 44 is opened and the pump 46 is operated. As described, this causes the fluid to enter the inner pipes 51, 51n. The pressure of the fluid acts on the top of the pistons 53,53n within the respective inner pipe 51,51n, resulting in the piston(s) 53,53n moving to the lowest position within the inner pipes Si, 51n (i.e. furthest from the top). Due to the connection of the pistons 52, 53, 53n through the pivot and crank assembly 59, the piston 52 will also move to an uppermost position. Then, the valve 44 can be closed and the pump 46 turned off. The fluid that was pumped into the inner pipe 30 will not fail down because of the damper or non-return valve (the damper allows the fluid to pass through one direction without return).

The second, third and fourth steps are then repeated as required.

By this method pumping of fluid can be achieved using a minimum amount of power (i.e. only opening and closing valves and running small pump) to a high region using the inner pipes 51,51n. Note that (n) can be any suitable number, for example (51,511,512,513"51n).By increasing the value of (n) the number of inner pipes is increased. This provides more quantity of fluid being pumped to the top per period or operational cycle,. In the same time it will decrease the height to which fluid can be pumped. , The selection will depend on what quantity of fluid is needed to be pumped and over what distance.

The present design enables the quantity of fluid that can be lifted to the top per cycle or period of time to be increased relative to known arrangements. By adding more pistons (n) which will carry the fluid to the top to increase the quantity of fluid to the top, and two small electrical pumps, the time between filling of the pistons and discharging them can be reduced, increasing the efficiency of the system.

Embodiments of the present invention have been described with particular reference to the examples illustrated. However, it will be appreciated that variations and modifications may be made to the examples described within the scope of the present invention.
