Abstract

PURPOSE:To make liquid pumping up easily at low cost and for long period with less energy by providing upper and lower valves at both the upper and lower ends of a guide tube, providing a passage in the guide tube at a position adjacent to the lower valve, providing an outlet at a part of the top end of the lifting tube, and providing an weight for keeping balance with the lifting tube in parallel to it. CONSTITUTION:When a lifting tube 5 is raised or an weight 14 is lowered by applying some force on it, a balance of weight of the lifting tube 5 plus liquid with the weight of the weight 14 is lost. A guide of a guide tube 6 is raised until it is stopped at an upper limit stopper 11 to raise liquid pressure and open an upper valve 12. A lower valve 9 remains closed. By this, liquid in the lifting tube 5 flows out from a flowing port 13. When the lifting tube 5 is lowered again back to the original position or the weight 14 is raised back to the original position, a balance of both right and left weights is kept. The guide of the guide tube 6 is lowered until it is stopped at a lower limit stopper 10 to close the upper valve 12 due to pressure of liquid in the lifting tube 5 and to open the lower valve 9 due to liquid in it. Thus liquid in the lifting tube 5 is kept again in stationary condition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pumping device for pumping up water, oil, and other liquids.

0002

BACKGROUND OF THE INVENTION Conventionally, suction pumps that lift liquid using limbs or power have required a large amount of energy proportional to the height of the place where the liquid is pumped and the amount of liquid pumped. Therefore, doing this work continuously for a long period of time resulted in accumulation of physical fatigue, and the cost was high due to the need for power.

0003

[Problems to be Solved by the Invention] Therefore, the present invention eliminates the above-mentioned drawbacks of the suction pump, and provides a means to easily pump liquid over a long period of time at low cost and without fatigue using very little energy. The purpose of this is to provide a device that can do this.

0004

[Means for Solving the Problems] First, an elevating cylinder with a guide pipe inserted into the upper opening of a field wall installed in a liquid tank is erected, and the upper and lower ends of the guide pipe are provided with an elevating cylinder. A valve and a lower valve are provided, an opening is provided in the guide pipe adjacent to the lower valve, an outlet is provided in a part of the upper end of the elevating tube, and a weight balanced with the elevating tube portion is arranged in parallel. This is a liquid pumping device consisting of:

[0005] Second, an elevating cylinder with a guide pipe inserted into the upper opening of the partition wall installed in the liquid tank is erected, and an upper valve and a lower valve are provided at both upper and lower ends of the guide pipe. , an opening is provided in the guide pipe adjacent to the lower valve, an outlet is provided in a part of the upper end of the elevator tube, and an elevator tube section of the same type that is balanced with the elevator tube section is installed in parallel. It is a device.

[0006]

[Operation] When the weight of the lift tube above the liquid tank and the liquid is equal to the weight of the weight, and the left and right sides are balanced,
The guide of the guide pipe under the elevator cylinder stops at the lower limit stop, and the upper valve closes and the lower valve opens due to the hydraulic pressure inside the elevator cylinder. At this time, the liquid in the elevator tube is in a stationary state. (See Figure 1)

0
[007] If the current force is applied to move the elevating tube upward or move the weight downward, the balance between the weight of the elevating tube and the liquid plus the weight of the weight will be lost, and the guide of the guide tube will move upward. The hydraulic pressure is increased and stopped at the upper limit stop, and the upper valve is opened, while the lower valve remains closed. This causes the liquid in the elevator cylinder to flow out from the outlet. (See Figure 2)

00
08] Next, when the elevating tube section is moved down to its original position or the weight is moved up to its original position, both the left and right sides are balanced, and the guide of the guide tube moves down and stops at the lower limit stop, but the upper The valve is closed by the hydraulic pressure in the elevator cylinder, and the lower valve is opened by the hydraulic pressure in the liquid tank. As a result, the liquid in the elevator cylinder remains stationary again. (See Figure 3)

[0009] When two elevating cylinders are installed in the liquid tank (
In FIG. 4), one of the elevating cylinders only plays the role of the weight, and its function is the same as when using the weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a liquid tank, and 2 denotes a wall body installed in the liquid tank 1. This wall body communicates with the liquid tank 1 through holes 3, 3 provided around the bottom of the wall body. Reference numeral 4 denotes an opening on the upper surface of the field wall body 2, and 5 denotes an elevating tube in which a guide tube 6 is inserted into the upper surface opening 4, and the inner circumferential surface of the field wall body 2 is slid onto the lower end of the guide tube portion. A movable guide 7 is provided. The guide pipe 6 on the upper side of the guide 7 has ports 8, 8 that communicate with the inside of the field wall body 2, and a lower valve 9 is provided on the guide 7 of the guide pipe 6 facing the ports 8, 8. will be established. 10, 10 is the lower limit stop of the guides 7, 7;
11, 11 are upper limit stops of the guides 7, 7. 1
2 is an upper valve provided on a guide pipe 6 connected to the elevating cylinder 5;
3 is an outlet opened in a part of the upper end of the elevating tube 5; 14;
is a weight, and the weight and the elevating cylinder 5 are connected in a well-balanced manner by a rope 16 via a fulcrum 15.

Note that FIG. 4 shows an embodiment of a twin tower type in which a similar elevating cylinder 5 device is provided in place of the weight 14.

Effects of the Invention In the device of the present invention, the gravity of the lift tube itself and the amount of liquid inside it is always balanced with the gravity of the weight, and when it is necessary to extract liquid, the gravity of the lift tube or the weight is balanced. By applying a slight force to the pump to break the balance between left and right gravity, it is possible to move the vertical cylinder inside the liquid tank upward and allow the liquid to easily flow out from its upper end. There is no fatigue at all, and the equipment cost is extremely low.Also, by installing two elevating cylinders in parallel in the liquid tank, liquid can be collected alternately on the left and right sides, making this device suitable for various types of equipment. It can be carried out in applications,
The effects are enormous.
