Description

Technical Field

[0001] The invention belongs to the field of mechanical design, and in particular relates to a method for a device capable of amplifying liquid pressure. Background Art

[0002] In all occasions around the world today, whether in high-tech, industrial, agricultural or daily life, if the pressure of a liquid needs to be raised from a low pressure state to a high pressure state, it is necessary to rely on equipment such as a high-pressure pump to achieve this. It requires a power source, electrical energy consumption or energy such as kerosene and gasoline to drive the high-pressure pump and other equipment to work, so as to achieve the purpose of raising the liquid from a low pressure to a high pressure. Once there is no power source, long-term outdoor or even field operations cannot be achieved. It cannot be achieved without a high-pressure pump, and the existing mechanical equipment for increasing pressure is generally bulky and inconvenient to carry and transport. Summary of the invention

[0003] The present invention provides a device capable of amplifying liquid pressure. The device can solve the problem of converting low-pressure liquid into high-pressure liquid or transporting low-altitude liquid to a higher altitude when there is no high-pressure pump or power supply and working outdoors. The device is power-free, portable, and suitable for all liquids that need to increase pressure. In any working environment, the user only needs to manually shake the rocker arm of the device up and down repeatedly (it can also be non-manual, which can be more efficient) to convert normal-pressure liquid (e.g., water in the wild) into a higher-pressure liquid. The specific steps include: In the initial state, all one-way switches are in the closed state, and the air ball valve switch is in the normal open state.

[0004] Shaking the rocker arm will lift the piston connected to the rocker arm. At this time, the one-way switch 4 is closed, the one-way switch 3 is opened, and the liquid enters from the water inlet.

[0005] Shaking the rocker arm will press the piston connected to the rocker arm downward. At this time, the one-way switch 3 is closed, the one-way switch 4 is opened, and the liquid enters the low-pressure chamber through the one-way switch 4.

[0006] Repeatedly shake the rocker arm up and down to continuously press the liquid from the one-way switch 4 into the low-pressure chamber.

[0007] As more and more liquid enters the low-pressure chamber, the air in the chamber is discharged from the air ball valve switch. When the liquid fills the entire low-pressure chamber and the hollow part on the left side of the transformer sleeve, the air ball valve switch automatically closes. When the rocker arm continues to be shaken to allow more liquid to enter, it will push the transformer sleeve to move to the right until it moves to the far right.

[0008] When the transformer sleeve moves to the rightmost position, the one-way switches 9 and 10 are triggered by the trigger switch and will open at the same time. The liquid enters the high-pressure chamber from the low-pressure chamber through the one-way switches 9 and 10. At the same time, since the one-way switches 9 and 10 are both opened, the pressure difference at both ends of the transformer sleeve disappears, and the transformer sleeve will move to the left under the action of the spring. When pulled back to the leftmost position, the one-way switches 9 and 10 are triggered by the trigger switch and closed at the same time.

[0009] Continue to shake the rocker arm, more liquid enters the low-pressure chamber, pushing the transformer sleeve to move to the right again. After reaching the rightmost side, the one-way switches 9 and 10 are opened again, and the liquid flows into the high-pressure chamber again. This cycle is repeated many times until the low-pressure chamber and the high-pressure chamber at both ends of the transformer sleeve are filled with liquid.

[0010] Continue to shake the rocker arm. Under the action of the rocker arm pressure, each time the transformer sleeve moves from left to right, a certain amount of liquid in the high-pressure chamber will be discharged from the water outlet due to the squeezing of the right side of the transformer sleeve.

[0011] Since the transformer sleeve is solid, solids only conduct force but not pressure. At this time, the rightward force F1 exerted on the contact surface between the hollow part on the left side of the transformer sleeve and the liquid is related to the pressure P1 of the liquid in the low-pressure warehouse on the left and the surface area S1 of the left side 8 (i.e., F1=P1*S1), while the leftward force F2 exerted on the contact surface between the right side of the transformer sleeve and the high-pressure warehouse liquid is related to the pressure P2 of the liquid in the high-pressure warehouse and the surface area S2 of the right side 14 (i.e., F2=P2*S2).

[0012] Since the radius R1 of S1 is larger than the radius R2 of S2 ( Figure 1 In the figure, R1:R2=3:1), and the area of ​​a circle is proportional to the square of its radius, so S1:S2=9:1. Since the interaction forces at both ends of the solid are equal in magnitude and opposite in direction, F1=F2, that is, P1*S1=P2*S2, then P1:P2=1:9, which means that the liquid pressure in the high-pressure chamber is 9 times that of the low-pressure chamber (if R1:R2=4:1, it is 16 times, and so on).

[0013] In order to better understand the principle of the device for amplifying liquid pressure, we can compare it with the working principle of the jack. The jack uses the characteristic that liquid only transmits pressure but not pressure. The two ends are solid and the middle is liquid. Then, the surface area of ​​the solid at one end is small and the surface area of ​​the solid at the other end is large, and the pressure of the liquid in contact is the same. According to the principle of F=P*S, when the pressure at both ends is the same but the area is different, the force is different, and the force is amplified, and a relatively heavy object (such as a car) can be lifted by relatively small manpower; while the present device uses the solid to only transmit force but not pressure. The two ends are liquid and the middle is a solid that can move left and right. According to the principle of F=P*S, when the force at both ends of the transformer sleeve is the same but the area is different, the pressure is different, and the pressure at one end is amplified. The surface area of ​​the transformer sleeve contacting the liquid is several times that of the other side, thereby amplifying the liquid pressure several times, and achieving the purpose of turning a relatively low-pressure liquid into a relatively high-pressure liquid.

[0014] Beneficial effects of the present invention: Compared with the prior art, a method for changing a liquid from a lower pressure to a higher pressure is provided. The method can be achieved by changing the length of the rocker arm (note: the distance from the fulcrum of the rocker arm to the piston connecting rod remains unchanged. When the length of the rocker arm is increased, the pressure acting on the piston can be increased due to the lever effect, thereby increasing the basic pressure of the low-pressure chamber, and thus the liquid pressure in the high-pressure chamber can be increased several times based on the basic pressure of the low-pressure chamber) or changing the surface area ratio of the two contact surfaces S1 and S2 at both ends of the transformer sleeve. After the liquid flows through the device, it can be changed from a low-pressure state to a high-pressure state. The whole process does not require power supply and is very convenient to carry. It can work normally for a long time without power supply or outdoors.

[0015] Of course, if the rocker arm is not manually rocked by hand, but driven up and down by a motor, the pressure amplification effect, water output and working efficiency of the device will be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] 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.

[0018] 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.

[0019] Specific implementation 1: The present invention can be widely used in equipment that needs to increase the pressure of liquid from low pressure to high pressure. Since the pressure of liquid (such as water) flowing through the equipment can be increased several times, it plays a very important role when high-pressure liquid is needed in real life and work (such as agricultural irrigation, gardening watering, high-pressure spraying of liquid, secondary water supply for high-rise buildings, water for high-rise fire fighting...etc.).

[0020] Combination Figure 1 As shown, the specific steps of using a device for amplifying liquid pressure of the present invention for agricultural irrigation are as follows: In the initial state, there is no liquid in the device but only air, all one-way switches are closed, and the air ball valve is naturally open.

[0021] First, connect one end of a water pipe of suitable thickness to the water inlet of the device, put the other end into the water of a pond, ditch or stream on the roadside of a rural area, and connect another water pipe of suitable thickness and sufficient length to the water outlet of the device.

[0022] When the rocker arm is shaken upward, the volume of the rocker arm cavity below the piston increases, and the gas pressure decreases, which drives the one-way switch 3 to open, and the gas in the water pipe connected to the water inlet is sucked in.

[0023] When the rocker arm is shaken downward, the volume of the rocker arm cavity below the piston becomes smaller and the gas pressure becomes larger. Since 3 is a one-way switch, the gas cannot flow back to the water pipe at the water inlet and can only drive the one-way switch 4 to open, and the gas in the rocker arm cavity is squeezed into the low-pressure chamber.

[0024] Continuously and repeatedly shaking the crank arm up and down will continuously suck the gas in the water pipe connected to the water inlet into the crank arm cavity and then squeeze it into the low-pressure chamber. Since the other end of the water pipe connected to the water inlet is underwater, the pressure of the remaining gas in the water pipe will become lower and lower until the water in the pond, ditch or stream at the other end of the water pipe is sucked into the water pipe. Continue to shake the crank arm until more and more water is sucked into the crank arm cavity and then flows to the low-pressure chamber.

[0025] As more and more water flows into the low-pressure chamber, the gas in the hollow part of the low-pressure chamber and the left side of the transformer sleeve is first discharged from the air ball valve at the top until the water fills to the height of the air ball valve. The air ball valve is then blocked by the buoyancy of the water.

[0026] Continue to shake the crank arm. More and more water will enter the hollow part of the low-pressure chamber and the left side of the transformer sleeve. The pressure on the left side of the transformer sleeve will become larger and larger. The water pressure will act on the left surface area to form a rightward thrust, gradually pushing the transformer sleeve to move to the right.

[0027] When the transformer sleeve moves to the far right, the one-way switches 9 and 10 are triggered to open at the same time, and water flows to the high-pressure chamber through the middle channel of the solid part on the right side of the transformer sleeve. At the same time, since the one-way switches at both ends of the solid part on the right side of the transformer sleeve are opened, the spaces at both ends of the low-pressure chamber and the high-pressure chamber are connected through the middle channel, causing the pressure difference on both sides of the transformer sleeve to disappear. At this time, the transformer sleeve moves to the left under the influence of the spring tension.

[0028] When the transformer sleeve moves to the far left, the one-way switches 9 and 10 are triggered to close again.

[0029] Continue to shake the rocker arm, and the transformer sleeve will continue to move from left to right. When it reaches the rightmost side, it will trigger the one-way switch to open. Then it will move back to the leftmost side due to the spring force, and then it will trigger the one-way switch to close and move to the right again... and the cycle will continue.

[0030] Every time the transformer sleeve moves from left to right, part of the water in the high-pressure chamber will be squeezed toward the outlet and sprayed out in a high-pressure state. Because it is high-pressure water, it can irrigate places far away from the stream, and even use the water in the stream at the foot of the mountain to irrigate the mountainside and the top of the mountain.

[0031] After the irrigation is completed using the device, remove the two tubes connected to the water inlet and the water outlet, continue to shake the rocker arm for a while to drain all the remaining liquid in the device, and tilt the device toward the water outlet at the same time to ensure that all the liquid is drained out for next use.

[0032] Specific implementation 2: The present invention can be widely used in equipment that needs to convert liquid into mist through a high-pressure nozzle. Since the pressure of the liquid (such as gasoline, diesel, paint, etc.) flowing through the equipment can be increased several times, it plays a very important role when other high-pressure mist liquids are needed in work such as painting furniture and machine tools, converting gasoline and diesel into mist to improve the combustion rate, etc.

[0033] Combination Figure 1 and Figure 4 As shown, the present invention can be designed not only horizontally but also vertically. The only difference is that the exhaust port and the air ball valve are adjusted to the position as shown in FIG. Figure 4 The specific steps of using the device for amplifying liquid pressure of the present invention in painting and other operations are as follows: Connect one end of a tube of suitable thickness to the water inlet and put the other end into the paint to be sprayed. At the same time, connect one end of another tube of suitable thickness to the nozzle and the other end to the water outlet.

[0034] According to the same operation steps as in Implementation 1, the rocker arm is repeatedly shaken to firstly discharge the gas in the device, and then the paint becomes high-pressure paint after passing through the device and is sprayed out through the nozzle to form a mist of paint, which is used for painting furniture and machine tools.

[0035] After use, continue to shake the rocker arm for a while to drain all the gasoline and paint in the device and leave them for the next use. If it is paint or other liquids that will dry and solidify, it is recommended to suck gasoline or other solvents from the water inlet for a while to clean the inner wall of the device after use, so as to prevent the paint from solidifying on the inner wall and affecting the next use.

[0036] Specific implementation 3: The present invention can also be widely used in high-rise buildings that require secondary water supply. Since the pressure of tap water flowing through the device can be increased several times, it plays a very important role in providing secondary water supply to high-rise buildings when the water supply pressure on floors in some areas (especially rural areas) is insufficient.

[0037] Combination Figure 1 and Figure 4 As shown, no matter the present invention is designed to be used horizontally or vertically, the specific steps of using the present invention for secondary water supply are as follows: First, move the device to the floor that needs secondary water supply (for example, if the building has 20 floors, but the tap water only reaches the 6th floor, then the device can be moved to the 6th floor), connect the tap to the water inlet of the device with a water pipe, and then connect another pipe to the water outlet of the device and connect the other end to the water reservoir on the top of the 20th floor.

[0038] According to the same operating steps as Implementation 1, the rocker arm is repeatedly shaken. Since the device can greatly increase the water pressure, tap water can be continuously lifted to the water reservoir on the 20th floor. When the pressure is found to be insufficient, the length of the rocker arm can be lengthened to increase the basic pressure through the lever action, thereby achieving secondary water supply.

[0039] Here is an additional principle analysis. We assume that the length of the rocker arm is L, the human force F is a constant, the base pressure of the low-pressure bin is P, and the device is designed with S1:S2=9:1, then the maximum pressure at the outlet is 9P. If we replace it with a rocker arm with a length of 2L, the base pressure of the low-pressure bin will be 2P, and the pressure at the outlet will be 18P, which is doubled year-on-year. In theory, the height of the secondary water supply can be doubled year-on-year.

[0040] After the secondary water supply is completed, remove the water pipes at the water inlet and outlet, and shake the shaking arm for a while to drain the water in the device. This can reduce the weight when portable and extend the service life of the device.

[0041] 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 spring is changed to a thrust force by changing its position, the manual rocker arm is changed to mechanical transmission or electric, the position of the air ball valve is adjusted... etc.), and any modification or equivalent replacement that does not deviate from the spirit and scope of the present invention should be included in the protection scope of the claims of the present invention.
