DETAILED DESCRIPTION

[0042] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The present invention discloses a Figure 1-2The energy storage construction site pressure water supply system shown in the figure includes three parts: a potential energy conversion system 1, an energy storage system 4, and a low-pressure water supply control system 5. The three parts are connected as a whole through multiple pipelines.

[0044] 1. Potential energy conversion system: The system structure is as follows Figure 3-7 As shown, it roughly includes a pressure pump 1-5, a crank shaft 1-3, a pressure plate 1-1, a pressure plate base 1-2 and a buffer spring 1-11.

[0045] The pressure pump 1-5 includes a pressure pump cylinder 1-16 and a pressure piston 1-4 slidably mounted therein. A pressure pump piston push rod 1-14 is connected to the top of the pressure pump piston push rod 1-14. An arc-shaped pressure pump head 1-12 is located at the top of the pressure pump piston push rod 1-14. The contact area between the pressure pump head 1-12 and the pressure rod of the crank shaft 1-3 is arc-shaped to reduce friction. Vertical plates are welded on both sides of the arc-shaped contact surface to form a limit plate structure to prevent the pressure rod of the crank shaft 1-3 from slipping. The piston upper limit limit rod 1-15 and the piston lower limit limit rod 1-13 are respectively used to limit the upper and lower movement limits of the pressure piston 1-4, preventing excessive displacement from damaging and failing the pressure pump cylinder 1-16. A booster pump inlet pipe 1-18 and a booster pump outlet pipe 1-7 are respectively provided below the booster pump cylinder body 1-16, and both pipes are provided with check valves. Among them, the booster pump inlet pipe check valve 1-6 is used to prevent the pressurized water in the booster pump cylinder body 1-6 from flowing back into the low-pressure water supply pipe 2 at the construction site, and the booster pump outlet pipe check valve 1-8 is used to prevent the pressurized water in the booster pipeline 3 from flowing back into the booster pump cylinder body 1-16 when water is replenished from the low-pressure water supply pipe 2 at the construction site after the booster piston 1-4 has finished descending.

[0046] The crank shaft 1-3 is an L-shaped structure, including a shaft rod and a pressure rod. The shaft rod is fixedly connected to one side of the pressure plate 1-1. When the pressure plate 1-1 drives the shaft rod to twist, it drives the pressure rod to rotate, and the pressure rod is pressed down away from the end of the shaft rod, thereby driving the piston push rod 1-14 to press down.

[0047] The pressure plate base 1-2 includes a bottom plate, a vertical support plate and a bearing. A vertical support plate is installed above the bottom plate to withstand the pressure from the upper pressure plate 1-1. A bearing is installed above the vertical support plate, and the bearing is rotatably connected to the crank shaft 1-3 to ensure that the pressure plate 1-1 and the crank shaft 1-3 can rotate freely within a certain range. The pressure plate 1-1 is fixedly connected to the crank shaft 1-3 through the crank shaft mounting hole, and the rotation of the pressure plate 1-1 drives the crank shaft 1-3 to rotate. A plurality of buffer springs 1-11 are installed on the pressure plate base 1-2 and opposite to the vertical support plate, and a cover plate 1-10 is mounted above the plurality of buffer springs 1-11. A plurality of buffer spring heads 1-9 are contact-connected above the cover plate 1-10. Multiple buffer springs 1-11 are connected as a whole by the cover plate 1-10 to buffer the impact force transmitted from the upper pressure plate 1-1, so that the pressurizing piston 1-4 runs smoothly. In addition, the buffer springs 1-11 can provide a certain supporting force to the pressure plate 1-1, so that the pressure plate 1-1 has the effect of a speed bump.

[0048] The pressure plate 1-1 consists of a curved panel, multiple reinforcing ribs 1-17 mounted below the curved panel, and multiple buffer spring heads 1-9 mounted below the curved panel, opposite the shaft mounting edge. The curved panel converts tire pressure from both directions into downward force on the pressure plate 1-11. The buffer spring heads 1-9, in conjunction with the buffer springs 1-11, partially transfer the instantaneous impact pressure from the tires to the springs, preventing excessive impact force from damaging the pressure pump cylinder 1-16.

[0049] 2. Energy storage system: The system is as Figure 8-12 As shown, it includes a pressure water storage tank body 4-4, a piston push rod 4-1, a counterweight frame 4-2, a movable counterweight 4-5 and a variable pressure counterweight 4-3.

[0050] The height and cross-sectional dimensions of the pressure water storage tank 4-4 are determined by the required water storage capacity of the system. It is connected to the foundation via the tank base. The lower portion of the pressure water storage tank 4-4 is equipped with a water tank inlet pipe 4-13, a water tank drain pipe 7, and a water tank outlet pipe 6. The water tank inlet pipe 4-13 is equipped with a water tank check valve 4-7 to prevent reverse flow of water in the pressurization pipeline 3. The water tank inlet pipe 4-13 is connected to the booster pump outlet pipe 1-7 via the pressurization pipeline 3 to replenish water in the pressure water storage tank 4-4. The water tank drain pipe 7 is equipped with a pressure control valve 4-6. When the pressure in the pressure water storage tank 4-4 exceeds the limit, the pressure control valve 4-6 opens, releasing pressure. The discharged water flows through the water recovery pipe 8 into the recovery system for reuse. The water tank outlet pipe 6 provides pressurized water, which is supplied to various devices via a pressure transformer.

[0051] A piston 4-10 is slidably mounted within the pressure water storage tank 4-4. A piston push rod 4-1 is connected to the top of the piston. The push rod 4-1 protrudes upward from the top of the pressure water storage tank 4-4 and is connected to the counterweight frame 4-2. The piston push rod 4-1 moves with the water level during the filling and storage of the pressure water storage tank 4-4, driving the counterweight frame 4-2 to move. The counterweight frame 4-2 is a straight line, cross, X-shaped or rice-shaped structure. Taking the cross structure as an example, the cross counterweight frame 4-2 includes a cross composed of two mutually perpendicular crossbeams 4-11 and four vertical rods 4-12 installed at the ends of the crossbeams 4-11. The four vertical rods 4-12 extend downward to the outside of the pressure water storage tank body 4-4. The outside of the four vertical rods 4-12 is jointly equipped with a mobile counterweight 4-5. The mobile counterweight 4-5 is arranged in blocks and is coaxially mounted on the outside of the four vertical rods 4-12. The number of blocks is configured according to the required water pressure. The weight of each ring structure is controlled at the same time, making installation and removal operations convenient. The crossbeams 4-11 and the vertical rods 4-12 together form a load-bearing structure that transmits the weight of the mobile counterweight 4-5 to the piston push rod 4-1 and can also limit the piston push rod 4-1 and the piston 4-10 from falling to the bottom position.

[0052] Slide rails 4-8 are installed on the outside of the pressure water storage tank body 4-4. A roller 4-9 is mounted at the lower end of each vertical rod 4-12. The rollers 4-9 are used to limit the movement of the counterweight frame 4-2. When the piston 4-10 drives the counterweight frame 4-2 up and down through the piston push rod 4-1, the rollers 4-9 engage the slide rails 4-8 and slide up and down along them, limiting the shaking of the counterweight frame 4-2 and reducing the friction caused by movement.

[0053] A variable pressure counterweight support is installed above the pressure water storage tank 4-4. A variable pressure counterweight 4-3 is mounted on the outside of the pressure water storage tank 4-4 and secured to the pressure water storage tank 4-4 via the variable pressure counterweight support. The function of the variable pressure counterweight 4-3 is to stabilize the pressure within the pressure water storage tank 4-4. When the counterweight frame 4-2 moves upward and the movable counterweight 4-5 strikes the variable pressure counterweight 4-3, the pressure within the pressure water storage tank 4-4 suddenly increases, exceeding the set value of the pressure control valve 4-6 on the water tank drain pipe 7, and water and pressure are released, ensuring the safety of the pressure water storage tank 4-4.

[0054] The inner ring of the mobile counterweight 4-5 is provided with both wide and narrow grooves. The wide groove's dimensions correspond to the shape of the slide rail 4-8, while the narrow groove's dimensions correspond to the shape of the variable pressure counterweight support. This prevents interference with the vertical movement of the mobile device 4-5 along the pressure water storage tank 4-4. The inner ring of the variable pressure counterweight 4-3 is provided with a wide groove, the dimensions of which correspond to the dimensions of the vertical rod 4-12, to prevent interference with the vertical movement of the vertical rod 4-12.

[0055] In the present application, the piston 4-10 can be provided without the piston push rod 4-1. In this case, the counterweight frame 4-2 is also omitted. The piston 4-10 inside the pressure water storage tank body 4-4 is connected to the movable counterweight 4-5 outside the pressure water storage tank body 4-4 through a magnetic connection, thereby achieving the purpose of synchronous movement. In this structure, the roller 4-9 is retained and directly mounted on the lower end of the movable counterweight 4-5. During the movement of the movable counterweight 4-5, it cooperates with the slide rail 4-8 to also serve as a guide.

[0056] 3. Low pressure water supply control system: Low pressure water supply control system such as Figure 13-15 As shown, it includes a system water supply control frame 5-5, a system water supply control connecting rod 5-1 and a gear rack mechanism.

[0057] The system water supply control frame 5-5 is a lattice-type component, fixed to the foundation with anchor bolts, on which the low-pressure water supply pipe 2 and the low-pressure water supply valve 5-4 are installed. The switch on the low-pressure water supply valve 5-4 is gear-shaped, and the tooth pitch of the gear switch 5-3 is the same as the tooth pitch of the rack 5-2 on the system water supply control connecting rod 5-1.

[0058] The system water supply control linkage 5-1 consists of a connecting plate and a rack 5-2. The connecting plate is located at the top and is connected to the outer surface of the movable counterweight 4-5. The rack 5-2 is mounted at the bottom of the connecting plate and is in driving connection with the gear switch 5-3. Driven by the movable counterweight 4-5, the rack 5-2 moves up and down, driving the gear switch 5-3 to rotate, thereby rotating the switch on the low-pressure water supply valve 5-4 to fully open and close.

[0059] 4. Water supply pipeline description: The low-pressure water supply pipe 2 is connected to the low-pressure water supply valve 5-4 and the booster pump water inlet pipe 1-18 to supply water to the booster pump 1-5.

[0060] The pressurized pipeline 3 connects the water inlet pipe 4-13 of the water storage tank and the water outlet pipe 1-17 of the pressure pump, and replenishes the pressurized water in the pressure pump 1-5 to the pressure water storage tank body 4-4.

[0061] The drain water recovery pipeline 8 is connected to the water storage tank drain pipe 7 and the recovery water storage tank for recovering the drain water for reuse.

[0062] The pressure water supply pipeline 9 collects the water from the water outlet pipe 6 of the water storage tank and supplies water to the equipment through the pipeline and the pressure changing valve.

[0063] 5. System Operation After the system is installed, a vehicle presses over the pressure plate 1-1, which drives the crankshaft 1-3 to rotate around the pressure plate base 1-2. This, in turn, drives the booster piston 1-4 in the booster pump 1-5 downward via the booster pump piston push rod 1-14, forcing the water in the booster pump cylinder 1-16 into the pressure water storage tank 4-4. After the vehicle passes, the pressure plate 1-1, under the restoring force of the buffer spring 1-11, drives the crankshaft 1-3 back to its original position. The booster piston 1-4 in the booster pump 1-5 is no longer under pressure on the upper side, and moves upward under the low-pressure water supply pressure on the lower side, returning to its original position and preparing for the next downward movement. As the amount of pressurized water entering the pressure water storage tank 4-4 increases, the piston 4-10 in the pressure water storage tank 4-4 moves upward, driving the counterweight frame 4-2 and the movable counterweight 4-5 upward via the piston push rod 4-1. During this process, the system can provide pressurized water to the outside through the pressure water supply pipeline 9. When the counterweight frame 4-2 and the movable counterweight 4-5 move upward, they drive the system water supply control connecting rod 5-1 to move upward. When it moves to the set position (such as the capacity of the pressure water storage tank body 4-4 reaches 80%), the serrated part of the rack 5-2 contacts the gear switch 5-3 of the low-pressure water supply valve 5-4, driving the gear switch 5-3 to close, and the low-pressure water supply pipe 2 is closed, stopping the water supply to the pressure pump 1-5. After the water in the pressure pump cylinder body 1-16 has been pressed out, the pressure piston 1-4 no longer rises. At this time, the pressure plate 1-1 will not generate pressure on the pressure pump 1-5 when it moves, and the water supply to the pressure water storage tank body 4-4 is stopped. The water level in the pressure water storage tank body 4-4 no longer rises, forming the first layer of protection. Under special circumstances, such as when low-pressure water supply valve 5-4 fails to close, the water level in pressure water storage tank 4-4 continues to rise. When the movable counterweight 4-5 rises to contact the variable pressure counterweight 4-3, piston 4-10 rises slowly, causing the pressure in pressure water storage tank 4-4 to suddenly rise, reaching the set value of pressure control valve 4-6, and water and pressure relief begin, forming a second layer of protection. After the pressurized water in pressure water storage tank 4-4 is used, the water level drops, and the serrated portion of rack 5-2 contacts the gear switch 5-3 of low-pressure water supply valve 5-4 again, causing the gear switch 5-3 of low-pressure water supply valve 5-4 to rotate in the opposite direction, and the low-pressure water supply pipeline resumes supplying water to booster pump 1-5.

[0064] During normal use, the pressure in the pressure water storage tank body 4-4 is constant, which is the ratio of the sum of the weight of the piston push rod 4-1, pressure piston 4-10, counterweight frame 4-2 and movable counterweight 4-5 of the pressure water storage tank body 4-4 to the internal cross-sectional area of the pressure water storage tank body 4-4.

[0065] Although the present invention has been described in detail with reference to the accompanying drawings and in conjunction with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, persons of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any changes or substitutions that can be easily conceived by persons skilled in the art within the technical scope disclosed in the present invention shall be within the scope of protection of the present invention.
