Description

Technical Field

[0001] The invention belongs to the field of mechanical design, and in particular relates to a method for delivering liquid from a low water level to a higher water level. Background Art

[0002] In today's world, regardless of high-tech, industrial, agricultural, daily life, firefighting and other occasions, if it is necessary to raise the liquid from a low water level to a high water level, it is necessary to rely on external energy to do work, such as using a water pump or other lifting methods, which requires consumption of electrical energy or other energy to drive mechanical work such as water pumps to achieve the purpose of raising the liquid from a low water level to a high water level, thereby consuming external energy or resources, and requiring external energy input to achieve the purpose of raising the liquid water level and increasing potential energy. Summary of the invention

[0003] The device for delivering liquid from a low water level to a higher water level of the present invention solves the problem that the flow of liquid from a low water level to a high water level can be achieved without external energy to do work, and specifically comprises the following steps: The one-way switch at the bottom of the water storage tank is opened, and the liquid flows from the one-way switch at the bottom of the water storage tank into the hollow area of ​​the upper sleeve of the piston sleeve. The piston sleeve is dropped to the lowest position under the gravity of the liquid.

[0004] After the liquid fills the hollow area (the air in the piston sleeve will automatically overflow from the top of the water storage tank through the one-way switch), close the one-way switch of the water storage tank, and then open the upper and lower piston one-way switches at the bottom of the piston sleeve.

[0005] When the piston one-way switch is turned on, part of the liquid flows into the bottom bin along the hole in the middle of the piston. The hydraulic pressure in the upper sleeve and the bottom bin are continuous and there is no hydraulic difference, which will not prevent the piston sleeve from rising. At this time, since the total weight of the heavy object is greater than the weight of the piston sleeve, the heavy object pulls the steel cable through the pulley and pulls the piston sleeve upward, and the piston sleeve begins to move upward.

[0006] The piston sleeve reaches the highest point, the bottom bin is filled with liquid, the up and down switches of the piston are closed, and the one-way switch at the bottom of the water storage bin is reopened.

[0007] The hydraulic pressure of the water storage tank is transmitted to the liquid in the hollow part of the upper part of the piston sleeve, acting on the surface area of ​​the bottom of the sleeve, forming a force F transmitted to the bottom of the piston. The bottom of the piston squeezes the liquid in the bottom tank to form a greater pressure than the liquid in the hollow part of the sleeve.

[0008] Note 1: The surface area S1 of the sleeve bottom is proportional to the square of the sleeve bottom radius, and the surface area S2 of the piston bottom is proportional to the square of the piston bottom radius. We can design the radius ratio of the upper and lower surfaces to be 2:1 (this ratio can be adjusted to 3:1 or even 4:1 as needed), then the ratio of the upper and lower surface areas is S1:S2=4:1 (when the upper and lower radius ratio is 3:1, S1:S2 is 9:1), the liquid pressure in the hollow part of the sleeve is P, then the bottom of the hollow part of the sleeve is subjected to a downward pressure of F=P1*S1 under the influence of hydraulic pressure, according to the principle of solid conduction force, the piston sleeve as a whole transmits the force F to the bottom of the piston, so the piston bottom F remains unchanged, and the pressure of the liquid in the bottom bin is P2=F / S2=P*S1 / S2=4P, considering that at this time, there is still a tension difference after the tension transmitted to the piston sleeve by multiple heavy objects through the pulley and the dead weight of the piston sleeve is offset, which may offset a small part of the downward pressure transmitted by the hydraulic pressure, then the pressure of the bottom bin is slightly less than 4P.

[0009] The pressure of the liquid in the bottom bin is slightly less than 4P, which is transmitted to the inner side of the one-way switch at the bottom of the outlet pipe through the liquid. At this time, the pressure outside the one-way switch of the outlet pipe is significantly lower than that inside. Since the height to which the water can rise is positively correlated with the bottom pressure, the liquid can be sent through the outlet pipe to a height slightly lower than 4 times the height H of the top of the water storage tank.

[0010] When all the liquid is discharged from the bottom bin, reopen the upper and lower one-way switches of the piston, and the liquid flows into the bottom bin again. The weight pulls the piston sleeve to the top again, and then close the upper and lower one-way switches of the piston, open the one-way switch of the water storage bin, and the liquid in the water storage bin enters the hollow part of the sleeve again, and the liquid (the volume each time is the same as the volume of the bottom bin) is sent to a higher water level again.

[0011] By repeating the above steps, the liquid equivalent to the volume of a bottom bin can be delivered to a higher water level each time.

[0012] Note 2: In fact, this device is the reverse application of a jack. The two ends of the jack are solid and the middle is liquid. The liquid is used to conduct pressure. The pressure at both ends of the liquid is the same, but the surface area of ​​the manual end in contact with the liquid is much smaller than the surface area of ​​the other end in contact with the liquid. According to the principle that force is equal to pressure multiplied by area, manpower can be magnified to lift much heavier objects. In the present invention, the two ends are liquid and the middle is solid. The solid can conduct force. When the two ends of the solid are subjected to the same force but the contact areas are different, the pressures of the liquids at both ends will be different. When the areas at both ends differ by several times, the pressures will also differ by several times. If the pressure increases by several times, the liquid can be sent to a liquid level several times the height of the liquid at the other end.

[0013] Beneficial effects of the present invention: Compared with the prior art, a method for delivering liquid from a low water level to a higher water level is provided. By changing the ratio of the bottom surface area S1 of the sleeve to the bottom surface area S2 of the piston, the liquid can be delivered from a low water level to a height several times or even dozens of times higher than the original liquid level after flowing through the device. The whole process does not require power consumption or external energy input to do work, and can be achieved by simply adjusting the surface area ratio of S1 and S2.

DETAILED DESCRIPTION

[0015] The following embodiments do not constitute any limitation to the protection scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present invention.

[0016] The technical scheme of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those generally understood by those of ordinary skill in the art to which the present application belongs.

[0017] Specific implementation 1: The present invention can be widely used in all equipment that needs to send liquid from a low water level to a high water level. Since each cycle can send a certain amount of liquid from a lower water level to a higher water level, it plays a very important role in the actual scene where liquids (such as irrigation water, oil, tap water for super high floors, water for fire fighting by fire trucks, etc.) need to be sent to higher water levels frequently.

[0018] Combination Figure 1 As shown, the specific steps of using the present invention to transport liquid from a low water level to a higher water level device are: In the initial state of the device after installation, the one-way switch of the water storage tank, the upper and lower one-way switches of the piston, and the one-way switch of the water outlet pipe are all closed, and then enough liquid is injected from the top of the water storage tank until it is full to the top.

[0019] Open the one-way switch at the bottom of the water storage tank, and the liquid enters the hollow part of the upper part of the piston sleeve from the water storage tank (the air is automatically discharged). The piston sleeve is lowered to the lowest position due to the liquid pressure. At this time, the space volume of the bottom tank is the smallest.

[0020] Close the one-way switch at the bottom of the water storage tank, open the upper and lower one-way switches on the piston part of the piston sleeve, and the liquid enters the bottom tank along the passage in the middle of the piston.

[0021] After part of the liquid enters the bottom bin, the pressure P2 of the liquid in the bottom bin is continuous and basically the same as the pressure P1 of the liquid in the sleeve. At this time, the downward pressure of the liquid on the piston sleeve disappears, and it begins to move upward under the upward pulling force of the weight.

[0022] When the piston sleeve moves to the uppermost position it can reach, the bottom bin is filled with liquid. After closing the upper and lower one-way switches of the piston, open the one-way switch at the bottom of the water storage bin to allow the liquid to re-enter the hollow part of the sleeve from the water storage bin.

[0023] After the liquid re-enters the hollow part of the sleeve, the height difference from the top of the water storage tank to the sleeve is set to H meters, and the transmitted pressure P makes the pressure of the liquid in the hollow part of the sleeve increase rapidly, and the pressure acting on the surface area S1 of the bottom of the sleeve increases rapidly, which means that the downward force F=P*S1 caused by the pressure on the entire piston sleeve increases rapidly by several times. At this time, in addition to this downward force, the piston sleeve is also subject to the gravity Mg1 of its own weight, and the upward force that can support the balance of the piston sleeve is only the surface area S2 of the bottom of the bottom bin in contact with the liquid and the force F2 generated by the pressure of the liquid in the bottom bin, in addition to the gravity Mg2 transmitted by the weight through the steel cable. In order to achieve balance, F+Mg1=F2+Mg2. Since the total weight of the weight is only slightly greater than the total weight of the piston sleeve, F2 should be only slightly less than F, which means that the pressure of the liquid in the bottom bin will rapidly increase to P3=F / S2=P*S1 / S2. Since S1 is several times of S2, it means that the pressure in the bottom bin has rapidly increased several times.

[0024] After the pressure in the bottom bin increases rapidly, it is transmitted to the one-way switch of the outlet pipe through the outlet pipe. A pressure difference is formed on both sides of the one-way switch, and the liquid is discharged from the outlet pipe. Since the height that the liquid can reach is positively correlated with the pressure, the height that the liquid in the outlet pipe can reach will be several times the liquid level height of the water storage tank. This multiple is determined by the multiple N of S1 to S2.

[0025] Since the device of the present invention can adjust the multiple of the height to which the liquid is delivered by changing the multiple N of S1 to S2, it can be widely used in equipment that needs to deliver liquid to a higher water level, such as oil pipelines, agricultural irrigation, and for example, in conjunction with the clamp on a drone to bring the water outlet to the air several times the height of a fire truck to extinguish a fire, etc.

[0026] Specific implementation 2: The present invention can be widely used in equipment that needs to use a limited amount of water to drive motors, windmills and other machinery to operate repeatedly, and has a good effect on saving electricity and other energy sources.

[0027] Combination Figure 2 As shown, the specific steps of using the present invention to deliver liquid from a low water level to a higher water level device, realizing the circulation of a limited amount of water in the device, and driving the motor, windmill and other machinery to operate repeatedly are as follows: Continue to operate the device of the present invention according to the same steps as in Implementation 1, but install a motor in front of the one-way switch of the water outlet pipe, and install the blades rotated by the motor exactly on the path through which the liquid flows out (as shown in the figure). At the same time, adjust the height of the water outlet of the water outlet pipe to be slightly higher than the height of the top of the water storage tank and align it with the water storage tank.

[0028] When the device is running, the high-pressure liquid will drive the impeller to rotate when flowing through the motor impeller, and at the same time consume part of the pressure potential energy of the high-pressure liquid. Since the pressure of the bottom bin is several times that of the hollow part of the sleeve, as long as the consumed potential energy is controlled within a limited range, the water in the outlet pipe will still have enough pressure to allow it to flow back to a height slightly higher than the top of the water storage bin. All the liquid will circulate in the water storage bin, the hollow part of the sleeve, the bottom bin, and the outlet pipe and then return to the water storage bin, thus achieving the purpose of driving the motor and other machinery to operate repeatedly through the circulation of a limited amount of water.

[0029] Here is a supplementary explanation: the one-way switch of the water storage tank, the two one-way switches above and below the piston, and the one-way switch of the water outlet pipe can all be achieved not only through electrical control, but also through appropriate mechanical design, through the pressure of the liquid and the piston sleeve moving up and down to drive the control fixture and switch.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the specific implementation modes of the present invention can still be modified or replaced by equivalents (for example, the tension of a weight, a steel cable, and a pulley combination can be replaced by the elastic force of a spring, etc.), and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
