Referring to fig. 1 to 9, an energy storage device according to a preferred embodiment of the present invention includes a body 10, a control valve 20, an elastic energy storage assembly 30, and a check valve 40.

The body 10 has a water inlet 11, a water outlet 12, an energy storage cavity 13, and a control valve port 15 for communicating the energy storage cavity 13 with the water outlet 12, wherein the water inlet 11 is communicated with the energy storage cavity 13. The control valve 20 includes a control valve core 21 movably disposed in the body 10 and engaged with the control valve port 15. When the control valve core 21 closes the control valve port 15, a water outlet cavity 16 is formed on the side of the control valve core 21 opposite to the energy storage cavity 13.

The energy accumulator also comprises a flow passage 14 formed on the body 10, one end of the flow passage 14 is communicated with the energy storage cavity 13, and the other end is communicated with the water outlet cavity 16. The elastic energy storage component 30 is movably arranged in the energy storage cavity 13.

When the water inlet 11 is not filled with water, the control valve core 21 closes the control valve port 15; when water enters the water inlet 11, water flows into the energy storage cavity 13 by overcoming the elastic force of the elastic energy storage assembly 30 and drives the elastic energy storage assembly 30 to store energy in the elastic energy storage assembly 30, when the elastic energy storage assembly 30 moves to a preset position, the overflowing channel 14 leads water, the water in the energy storage cavity 13 flows into the water outlet cavity 16 through the overflowing channel 14, one side of the control valve core 21, which faces away from the energy storage cavity 13, is under the action of water pressure, so that the resultant force direction of the control valve core 21 is towards the direction of opening the control valve port 15 to open the control valve port 15, the water in the energy storage cavity 13 is discharged to the water outlet 12 together with the water at the water inlet through the control valve port 15 under the action of the elastic energy storage assembly 30, and the water flow pressure and the water flow rate of the water outlet 12. The hydraulic feedback of the overflowing channel 14 is adopted to open the control valve port 15, so that the structure is simple, the design is ingenious, and the function is reliable.

In this embodiment, the control valve core 21 is provided with a second sealing element 212, when the control valve core 21 closes the control valve port 15, the second sealing element 212 separates the water outlet cavity 16 from the water outlet 12, and when the control valve core 21 opens the control valve port 15, the second sealing element 212 is driven to communicate the water outlet cavity 16 with the water outlet. Therefore, the water flow of the flow passage 14 does not flow out of the water outlet 12 immediately after flowing to the water outlet cavity 16, and the water flow is accumulated in the water outlet cavity 16, so that the side, facing away from the energy storage cavity 13, of the control valve core 21 is subjected to the action of water pressure, and further the resultant force direction applied to the control valve core 21 is towards the direction of opening the control valve port 15 so as to open the control valve port 15, and the function is more reliable. Of course, when the control valve core 21 closes the control valve port 15, it is not necessary that the water outlet cavity 16 is separated from the water outlet 12, for example, when the pipe resistance of the pipeline connected to the water outlet 12 is large (for example, when the diameter of the pipeline is small), the water flowing through the overflow channel 14 will not flow out of the water outlet 12 immediately after flowing into the water outlet cavity 16, as long as the water flowing through the overflow channel 14 to the water outlet cavity 16 can form a water pressure on the side of the control valve core 21 facing away from the energy storage cavity 13.

In order to further enable the control valve core 21 to smoothly close the control valve port 15, in this embodiment, an overflow aperture 161 is further disposed between the water outlet cavity 16 and the water outlet 12, and when the water outlet cavity 16 is separated from the water outlet 12, water in the water outlet cavity 16 is discharged to the water outlet 12 through the overflow aperture 161. Through setting up this small hole 161 that overflows for when water inlet 11 stopped intaking, the hydroenergy of play water cavity 16 can be let out by overflowing small hole 161, thereby avoids going out water cavity 16 and holds out the problem that water leads to control valve core 21 can't close control valve port 15, and the function is more reliable. Of course, in the present embodiment, the control valve body 21 and the control valve port 15 are end face sealed, and therefore, the small flow passage hole 161 may not be provided, but the small flow passage hole 161 is preferably provided.

In this embodiment, when the water inlet 11 is not filled with water, the elastic energy storage assembly 30 abuts against the control valve core 21 so that the control valve core 21 closes the control valve port 15; when water enters the water inlet 11 and the elastic energy storage assembly 30 is not moved to a preset position, the control valve core 21 keeps closing the control valve port 15 under the action of water pressure, so that the control valve core 21 can close the control valve port 15 in the process of storing water by the energy storage device, and water entering the energy storage cavity 13 is prevented from flowing out of the control valve port 15.

Referring to fig. 6, 7 and 8, in the present embodiment, the control valve 20 further includes a control valve seat 23, a hollow valve cavity is formed in the control valve seat 23, and the control valve core 21 is movably disposed on the control valve seat 23. The control valve seat 23 is provided with a through-flow ring groove 231 communicating the inside and the outside of the valve cavity and a through hole 232 communicating the inside and the outside of the valve cavity, water in the energy storage cavity 13 flows into the valve cavity through the through-flow ring groove 231 to form water pressure on the control valve core 21, a linkage rod 211 arranged on the control valve core 21 can penetrate through the through hole 232, and the elastic energy storage assembly 30 is in linkage fit with the linkage rod 211 on the control valve core 21 to drive the control valve core 21 to close the control valve port 15. The outer peripheral wall of the control valve seat 23 is further provided with a rib 233, and when the control valve seat 23 is installed in the main body 10a, the rib 233 is in circumferential limit fit with a groove (not shown) provided on the inner wall of the main body 10a, so that the control valve seat 23 does not rotate circumferentially relative to the main body 10 a.

In other embodiments, when the elastic energy storage assembly 30 abuts against the control valve core 21, a water flow gap is formed between the elastic energy storage assembly 30 and the control valve core 21, so that the side of the control valve core 21 facing the elastic energy storage assembly 30 can be subjected to the acting force of water pressure. By providing the water flow gap, on one hand, water can flow to one side of the control valve core 21 facing the elastic energy storage assembly 30 to apply water pressure to the control valve core 21, so that the control valve core 21 moves towards the direction of closing the control valve port 15 under the action of the inlet water pressure to close the control valve port 15; on the other hand, the problem that the control valve port 15 cannot be closed in the process of storing water in the energy storage device by the control valve core 21 due to the fact that the elastic energy storage assembly 30 is attached to the control valve core 21 and the elastic energy storage assembly 30 attracts and moves the control valve core 21 in the direction away from the control valve port 15 when moving under the action of water pressure is avoided.

When the overflow channel 14 is filled with water, the mode of automatically opening the control valve port 15 by the control valve core 21 can be designed according to the requirement, for example: the control valve spool 21 is used to open the control valve port 15 by the resultant force of the water pressures on both sides of the control valve spool 21, and/or the control valve spool 21 opens the control valve port 15 by the external force acting on the control valve spool 21, and/or the control valve spool 21 opens the control valve port 15 by its own weight, and the like. Specifically, in this embodiment, when water flows through the flow passage 14, one side of the control valve element 21 facing away from the energy storage cavity 13 is subjected to water pressure, and when the pressure of the water on the side of the control valve element 21 facing away from the energy storage cavity 13 is greater than the pressure of the water on the side of the control valve element 21 located in the energy storage cavity 13, the control valve element 21 opens the control valve port 15 by the resultant force of the water pressures on the two sides of the control valve element 21 and by the elastic force of the first elastic member 22 described below.

Specifically, in the present embodiment, the control valve 20 includes the first elastic element 22 acting on the control valve core 21, and the elastic force of the first elastic element 22 is overcome when the control valve core 21 closes the control valve port 15, that is, when the control valve core 21 closes the control valve port 15, the first elastic element 22 is in an elastic deformation state to apply an elastic force to the control valve core 21, and at this time, the elastic force applied to the control valve core 21 by the first elastic element 22 is smaller than the water inlet pressure applied to the control valve core 21 by the accumulator 13, so as to ensure that the control valve core 21 keeps closing the control valve port 15 under the action of the water inlet pressure. When the overflowing channel 14 is opened, the resultant force of the elastic force exerted by the first elastic element 22 on the control valve core 21 and the water pressure exerted on the side of the control valve core 21 opposite to the energy accumulator 13 is greater than the water pressure exerted on the side of the control valve core 21 on the energy accumulator 13, and the control valve core 21 opens the control valve port 15 under the resultant force of the water pressures on the two sides of the control valve core 21 and the external force provided by the first elastic element 22. The control valve core 21 further opens the control valve port 15 automatically by the elastic external force provided by the first elastic member 22, which is more reliable. Of course, in the present embodiment, the resultant action of the water pressures on both sides of the control valve element 21 can cause the control valve element 21 to smoothly open the control valve port 15, so the first elastic element 22 may not be provided.

In this embodiment, the elastic energy storage assembly 30 includes a piston 31 and a second elastic member 32 acting on the piston 31, a sealing member 33 is disposed on a head portion of the piston 31, and the piston 31 forms a dynamic seal with an inner wall of the energy storage cavity 13 through the sealing member 33. The sealing member 33 seals the energy storage chamber 13 into a first chamber 131 and a second chamber 132, the first chamber 131 is communicated with the water inlet 11 and the control valve port 15, and the second chamber 132 is communicated with the outside.

In this embodiment, a check valve 40 is also included for controlling the opening and closing of the transfer passage 14. The overflowing channel is provided with a check valve port 141, and when the overflowing channel 14 is filled with water, the check valve 40 opens the check valve port 141 under the action of the water pressure of the overflowing channel 14.

The check valve 40 includes a check valve body 41 engaged with the check valve port 141 and a fourth elastic member (not shown) acting on the check valve body 41, the check valve body 41 closes the check valve port 141 by an elastic force of the fourth elastic member, and the flow of the water through the flow passage 14 opens the check valve port 141 by overcoming the elastic force of the fourth elastic member.

In order to make the overall layout of the energy storage device reasonable, the structure is compact, and the forming is convenient, in this embodiment, the body 10 includes a main body 10a and a top cover 10b, the water inlet 11, the water outlet 12, the energy storage cavity 13 and the control valve port 15 are all formed on the main body 10a, one end of the energy storage cavity 13 far away from the water outlet 12 forms an opening, the control valve 20 and the elastic energy storage assembly 30 are arranged in the energy storage cavity 13 through the opening, and the top cover 10b is covered and connected at the opening, so that the assembly of the energy storage device is more convenient, and the assembly efficiency is.

In this embodiment, the first elastic member 22, the second elastic member 32, and the fourth elastic member are compression springs. And the elastic force of the second elastic member 32 is greater than that of the first elastic member 22.

When in use, please refer to fig. 2 and fig. 3, in an initial state, water does not enter the water inlet 11, at this time, the control valve core 21 closes the control valve port 15 under the pressing of the elastic energy storage assembly 30, and the flow passage 14 is in a water-free state. Referring to fig. 4, when water enters the water inlet 11, the water flows into the energy storage cavity 13 against the elastic force of the elastic energy storage assembly 30, and the control valve core 21 keeps closing the control valve port 15 against the elastic force of the first elastic element 22 under the action of the water pressure in the energy storage cavity 13. With the continuous entering of the water flow into the energy storage cavity 13, the water flow drives the elastic energy storage assembly 30 to make the piston 31 of the elastic energy storage assembly 30 move downward and compress the second elastic member 32 for energy storage, until the elastic energy storage assembly 30 moves to a predetermined position, the sealing member 33 of the elastic energy storage assembly 30 passes through the opening end of the flow passage 14 communicated with the energy storage cavity 13, the flow passage 14 is communicated with the first cavity 131 in the energy storage cavity 13, so that the flow passage 14 is communicated with the water, and the water flow in the energy storage cavity 13 flows to the water outlet cavity 16 through the flow passage 14.

Referring to fig. 5, when there is water flow in the water outlet cavity 16, one side of the control valve core 21 facing away from the energy storage cavity 13 is subjected to water pressure, and at this time, a resultant force of an elastic force exerted by the first elastic member 22 on the control valve core 21 and the water pressure exerted by one side of the control valve core 21 facing away from the energy storage cavity 13 is greater than the water pressure exerted by one side of the control valve core 21 on the energy storage device 13, taking the direction of fig. 5 as an example, the control valve core 21 moves upward and opens the control valve port 15, and at this time, the water in the energy storage cavity 13 is discharged from the control valve port 15 under the action of the elastic energy storage assembly 30 and flows out from the water outlet 12 together with the water in the water inlet 11, so that the water flow pressure and the water flow rate flowing out of the.

After the water in the energy storage cavity 13 is discharged, because the elastic force of the second elastic element 32 is greater than the elastic force of the first elastic element 22, the elastic energy storage assembly 30 re-abuts against the linkage rod 211 on the control valve core 21, so that the control valve core 21 can overcome the elastic force of the first elastic element 22 and be located at a position for closing the control valve port 15.
