Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic ram pumps, and specifically to a water lifting device that utilizes water energy. Background Technique

[0002] A hydraulic ram pump is a lifting device that utilizes the water hammer principle. Without external power, it uses the height difference of water, coordinates with a pressure relief valve group and a water supply valve group to automatically transport water to a high place, and introduces it into a pressure buffer tank to coordinate the pressure and ensure long-term use. However, the following problems occur in the existing hydraulic ram pumps during use:

[0003] For the installation of a hydraulic ram pump, the limitations of terrain and location need to be considered, and thus the water pressure utilized varies. The existing hydraulic ram pumps are not convenient for adjusting the pressure relief resistance according to the water pressure magnitude, resulting in different pressure relief effects, affecting the water supply pressure of its water hammer effect. At the same time, the pressure relief valve group discharges water and pushes it through water pressure in the early stage, and then realizes water supply through the water hammer effect after closing. The existing hydraulic ram pumps are not convenient for adjusting the pressure relief frequency. When the pressure is small, if the fixed pressure relief frequency is continued to be used, then the water supply frequency will inevitably be affected, affecting the overall use efficiency.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original hydraulic ram pump. Summary of the Invention

The limiting rod fixed at the bottom edge of the limiting plate is clamped in the top cavity of the limiting ring. A central rod is threadedly connected to the middle of the limiting plate. A sealing plate is fixed at the bottom of the central rod. The top of the central rod is connected to a support plate through an elastic telescopic rod. The support plate is located in an installation sleeve. An installation frame is sleeved outside the installation sleeve. The installation frame is fixed to the top of the water discharge valve seat through a rod. A screw rod penetrates through the top of the installation sleeve, and the bottom of the screw rod abuts against the top of the support plate.

[0008] A movable assembly, wherein the movable assembly is disposed between the support plate and the mounting sleeve, and the support plate is vertically moved by the movable assembly when rotating;

[0009] An area adjustment component is arranged below the support plate and inside the sealing plate, and is used to adjust the cross-sectional area of ​​the sealing plate.

[0010] Preferably, the movable component comprises a guide head and a guide groove, the guide head is fixed on the outer side of the support plate, the outer end of the guide head is located in the guide groove, and the guide groove is provided on the inner wall of the mounting sleeve.

[0011] Preferably, the guide head slides in the guide groove, and the guide groove is distributed in a spiral structure in the mounting sleeve.

[0012] Preferably, the moving speed of the support plate when rotating is greater than the moving speed of the center rod when rotating, and the moving speed of the center rod when rotating is less than the moving speed of the screw when rotating, and the moving speed of the screw corresponds to the moving speed of the support plate.

[0013] Preferably, the area adjustment component includes an oil tank, which is fixed to the outer side of the top of the center rod, a first piston rod is arranged in the oil tank, and the top of the first piston rod is fixed to the bottom of the support plate, the oil tank is connected to an oil cavity through a hose, the oil cavity is embedded in the sealing plate, a second piston rod is arranged in the oil cavity, a push head is fixed to the bottom of the second piston rod, the push head is embedded and slidably arranged in the internal cavity of the sealing plate, a cross bar is arranged on the side of the bottom of the push head, an amplification plate is fixed to the outer end of the cross bar, and the amplification plate is slidably arranged in the cavity outside the sealing plate.

[0014] Preferably, the first piston rod drives the center rod and the support plate to rotate synchronously, and the moving direction of the first piston rod is the same as the moving direction of the second piston rod.

[0015] Preferably, the bottom of the pusher head is designed as an inverted truncated cone structure, the inclined surface of the bottom of the pusher head conflicts with the cross bar, and the cross bar and the amplification plate are distributed at equal angles in the sealing plate.

[0016] Preferably, the top of the water supply pipe is connected to a pressure buffer tank, a water supply port and a sewage outlet are respectively provided on both sides of the pressure buffer tank, an air supply port is provided on the pressure buffer tank, and manual valves are installed on the water supply port, the sewage outlet and the air supply port.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, in the case of water areas with different pressures, the central rod and the screw rod are rotated. Under the restrictive action of the limiting rod, the central rod threadedly connected to the limiting rod can move vertically, driving the sealing plate to move vertically and adjusting the distance between it and the limiting ring. That is, the smaller the water pressure, the closer the distance between the sealing plate and the limiting ring. Furthermore, the smaller the water pressure, the smaller the stroke required for the water in the water inlet pipe to push the sealing plate to close, resulting in a higher frequency of the water hammer effect. Through high-frequency water supply, the gap in the low water intake when the water pressure is small is compensated, ensuring the water intake efficiency. At the same time, the increased frequency of the sealing plate when the water pressure is small will not affect its service life.

[0019] In the present invention, during the rotation and vertical upward movement of the central rod, the support plate is driven to rotate through the elastic telescopic rod. Under the action of the guiding head and the guiding groove, the moving speed of the support plate is greater than that of the central rod, so that the elastic force of the elastic telescopic rod is released. When the subsequent water flow pushes the sealing plate upward, the resistance provided by the elastic telescopic rod decreases, adjusting the pressure relief resistance. When the water pressure is small, the water hammer effect can also be better provided. Further, the generation of the distance difference between the support plate and the central rod can adjust the position of the pushing head through the oil tank, the first piston rod, the oil cavity and the second piston rod, and then adjust the position of the amplification plate in the sealing plate. That is, the smaller the water pressure, the smaller the protruding area of the amplification plate, further reducing the resistance. On the contrary, the greater the water pressure, the greater the resistance of the elastic telescopic rod and the amplification plate, which can ensure that the water hammer effect has sufficient water lifting force and avoid excessive pressure relief, protecting the internal components.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution: a water lifting device using water energy, including a water inlet pipe 1, a base 2, a drain valve seat 3, a limit ring 4, a limit plate 5, a limit rod 6, a center rod 7, a sealing plate 8, an elastic telescopic rod 9, a support plate 10, a guiding head 101, a guiding groove 102, a mounting sleeve 11, a screw 12, a mounting bracket 13, an oil tank 141, a first piston rod 142, an oil chamber 143, a second piston rod 144, a pushing head 145, a cross bar 146, an amplification plate 147, an upper water pipe 15, a pressure buffer tank 16, a check valve 17, a water inlet 18 and a sewage outlet 19.

[0029] Embodiment 1

[0030] Please refer to Figures 1-3, a base 2 is rotatably installed at the bottom of the water inlet pipe 1, and the top of the middle part of the water inlet pipe 1 is flange-connected to an upper water pipe 15 with an internal check valve 17; an opening is provided at the top of the drain valve seat 3 and is flange-connected to one end of the water inlet pipe 1 away from the water inlet. A limiting ring 4 is fixed on the inner wall of the middle part of the drain valve seat 3. A limiting plate 5 is arranged on the top of the limiting ring 4. A limiting rod 6 fixed at the bottom edge of the limiting plate 5 is clamped in the top cavity of the limiting ring 4. A central rod 7 is threadedly connected to the middle part of the limiting plate 5. A sealing plate 8 is fixed at the bottom of the central rod 7. The top of the central rod 7 is connected to a support plate 10 through an elastic telescopic rod 9. The support plate 10 is located inside the mounting sleeve 11. An installation frame 13 is sleeved outside the mounting sleeve 11. The installation frame 13 is fixed to the top of the drain valve seat 3 through a rod. A screw rod 12 is installed through the top of the mounting sleeve 11, and the bottom of the screw rod 12 abuts against the top of the support plate 10; the top of the upper water pipe 15 is connected to a pressure buffer tank 16. Water inlets 18 and a sewage outlet 19 are respectively arranged on both sides of the pressure buffer tank 16. An air inlet is provided on the pressure buffer tank 16. Manual valves are installed on the water inlet 18, the sewage outlet 19 and the air inlet.

[0031] When dealing with different water pressures, rotate the central rod 7 and the screw rod 12. The screw rod 12 rotates and moves vertically within the limiting plate 5 to adjust the distance between the sealing plate 8 and the limiting ring 4, thereby adjusting the water outlet and closing stroke here, increasing the frequency of the water hammer effect. Thus, even when the pressure is relatively small, efficient water intake operation can be ensured. When the water hammer effect occurs, the water is led out from the water inlet 18 through the cooperation of the check valve 17 and the pressure buffer tank 16, and the internal sewage is discharged through the manual control of the sewage outlet 19 subsequently.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, please refer to Figures 1-6 , the movable assembly is arranged between the support plate 10 and the mounting sleeve 11. When the support plate 10 rotates, it moves vertically through the movable assembly; the movable assembly includes a guiding head 101 and a guiding groove 102. The guiding head 101 is fixed on the outside of the support plate 10, and the outer end of the guiding head 101 is located in the guiding groove 102. The guiding groove 102 is opened on the inner wall of the mounting sleeve 11; the guiding head 101 fits and slides in the guiding groove 102, and the guiding groove 102 is distributed in a spiral structure inside the mounting sleeve 11; the moving speed of the support plate 10 during rotation is greater than the moving speed of the central rod 7 during rotation, the moving speed of the central rod 7 during rotation is less than the moving speed of the screw rod 12 during rotation, and the moving speed of the screw rod 12 corresponds to the moving speed of the support plate 10;

[0034] The central rod 7 drives the support plate 10 to rotate, and drives the support plate 10 to move through the guiding head 101 and the guiding groove 102, so that the moving speed of the support plate 10 is greater than the moving speed of the central rod 7, adjusting the resistance of the elastic telescopic rod 9 to be applicable to the change of water pressure;

[0035] The area adjustment assembly is arranged below the support plate 10 and inside the sealing plate 8. The area adjustment assembly is used to adjust the cross-sectional area of the sealing plate 8. The area adjustment assembly includes an oil tank 141, which is fixed on the outer side of the top of the central rod 7. A first piston rod 142 is arranged in the oil tank 141, and the top of the first piston rod 142 is fixed to the bottom of the support plate 10. The oil tank 141 is connected to an oil cavity 143 through a hose. The oil cavity 143 is embedded in the sealing plate 8. A second piston rod 144 is arranged in the oil cavity 143. A push head 145 is fixed to the bottom of the second piston rod 144. The push head 145 is embedded and slidably arranged in the inner cavity of the sealing plate 8. A cross bar 146 is arranged on the side of the bottom of the push head 145. An amplification plate 147 is fixed to the outer end of the cross bar 146. The amplification plate 147 is fitted and slidably arranged in the outer cavity of the sealing plate 8. The first piston rod 142 drives the central rod 7 and the support plate 10 to rotate synchronously. The moving direction of the first piston rod 142 is the same as the moving direction of the second piston rod 144. The bottom of the push head 145 is designed as an inverted frustum-shaped structure. The bottom inclined surface of the push head 145 abuts against the cross bar 146. The cross bar 146 and the amplification plate 147 are equally angularly distributed in the sealing plate 8.

[0036] When the support plate 10 moves by itself, the position of the first piston rod 142 in the oil tank 141 is adjusted, and then the position of the second piston rod 144 in the oil cavity 143 is adjusted. The position of the amplification plate 147 is adjusted through the cooperation of the push head 145 and the spring, and then the contact area between the sealing plate 8 and the amplification plate 147 and water is adjusted, and the resistance is further adjusted.

[0037] Working principle: When using the water-lifting device utilizing water energy, first, according to the unevenness and flatness of the installation position, rotate the base 2 and fix it with bolts. Install the base 2 on the ground through fasteners to ensure that the water inlet pipe 1 is in a horizontal position. According to the water pressure, rotate the central rod 7 and the screw rod 12, and corresponding scales are set on the central rod 7 and the screw rod 12 to distinguish the adjustment range. The central rod 7 is threadedly connected to the limit plate 5, and the position of the limit plate 5 is restricted by the limit rod 6, so that the central rod 7 can move vertically when rotating. When the water pressure is small, the central rod 7 moves upward, driving the sealing plate 8 to move upward, adjusting the distance between the sealing plate 8 and the limit ring 4. At the same time, the central rod 7 drives the support plate 10 to rotate, and the support plate 10 moves synchronously under the guiding action of the guiding head 101 and the guiding groove 102, so that the moving speed and distance of the support plate 10 are greater than the moving distance of the central rod 7. As a result, part of the elastic force of the elastic telescopic rod 9 is released, and the resistance received by the sealing plate 8 when driving the central rod 7 to move upward subsequently is reduced. The movement of the support plate 10 drives the first piston rod 142 to move in the oil tank 141, so that the internal space of the oil chamber 143 is vacated. The pulling force provided by the spring at the amplification plate 147 can push the push head 145 and the second piston rod 144 upward through the cross bar 146, adjusting the extending length of the amplification plate 147, and further adjusting the contact area between the sealing plate 8 and the amplification plate 147 and water, and further adjusting the resistance. The rotation of the screw rod 12 aims to limit the position of the support plate 10 after adjustment, preventing the support plate 10 from moving upward synchronously under the thrust at the bottom and ensuring a stable resistance for the elastic telescopic rod 9;

[0038] After adjustment, connect the water inlet pipe 1 to the water inlet waterway, and connect the water supply waterway to the water supply pipe 15. Water flows into the water inlet pipe 1, pushing the sealing plate 8 upward. Part of the water is discharged from the upper opening of the drain valve seat 3 through the gap between the sealing plate 8 and the limit ring 4. The sealing plate 8 drives the central rod 7 to move upward, providing resistance through the elastic telescopic rod 9 and facilitating subsequent reset. When the sealing plate 8 abuts against the limit ring 4, the water flow inside the water inlet pipe 1 is cut off, generating a water hammer effect, pushing the check valve 17 open, transporting the water to the water outlet 18, and cooperating with the pressure buffer tank 16 to realize the re-closure of the check valve 17. Repeat the above steps to achieve continuous water supply operation. During subsequent maintenance, discharge the sewage deposited inside through the sewage outlet 19.
