Referring to fig. 1 to 9, an energy storage device according to a preferred embodiment of the present invention includes a main body 10, a main control valve 20, an energy storage assembly, a sub-control valve 40, and a transmission mechanism 50.

The body 10 is provided with a water inlet 11, a water outlet 12 and an energy storage cavity 13, and the water inlet 11 and the water outlet 12 are communicated with the energy storage cavity 13. The inflow water of the water inlet 11 flows into the energy storage cavity 13 and then is stored in the energy storage cavity 13, the energy storage assembly stores energy, and when the inflow water reaches a preset inflow amount, the energy storage assembly automatically releases energy storage, so that the water in the energy storage cavity 13 and the inflow water flow out from the water outlet 12 together.

In this embodiment, the body 10 further has an overflow channel 14 for communicating the water inlet 11 and the water outlet 12, and a main valve port 15 for communicating the energy storage chamber 13 and the water outlet 12. The main control valve 20 includes a main spool 21 movably disposed within the body 10 and cooperating with the main valve port 15. The energy storage component is an elastic energy storage component 30, and the elastic energy storage component 30 is movably arranged in the energy storage cavity 13.

In the state of no water supply to the water inlet 11, the main valve element 21 closes the main valve opening 15 and the overflow channel 14 is closed. When the water inlet 11 is filled with water, the water flow overcomes the elastic force of the elastic energy storage assembly 30 and flows into the energy storage cavity 13 and drives the elastic energy storage assembly 30 to store energy in the elastic energy storage assembly 30. When the inflow of the water inlet 11 reaches a preset inflow to enable the elastic energy storage assembly 30 to move to a preset position, the overflowing channel 14 is opened, so that one side, back to the energy storage cavity 13, of the main valve core 21 is under the action of water pressure to open the main valve port 15, then the water in the energy storage cavity 13 is discharged from the main valve port 15 under the action of the elastic energy storage assembly 30 and flows out of the water outlet 12 together with the water in the water inlet 11, and therefore the water flow pressure and the water flow rate of the water outlet 12 can be effectively improved.

Specifically, referring to fig. 8 and 9, in the present embodiment, the main body 10a is formed with a water inlet passage 17 and a water outlet passage 18. The water inlet 11 forms a water inlet end of the water inlet channel 17, a water outlet end of the water inlet channel 17 is divided into a first water outlet end 171 and a second water outlet end 172, the first water outlet end 171 is communicated with the energy storage cavity 13, and the water inlet 11 is communicated with the energy storage cavity 13 through the water inlet channel 17 and the first water outlet end 171. The second water outlet end 172 is communicated with the overflow channel 14, and the water inlet 11 is communicated with the overflow channel 14 through the water inlet channel 17 and the second water outlet end 172. The outlet 12 forms the outlet end of an outlet passage 18, the inlet end of the outlet passage 18 communicating with an outlet chamber 16 described below.

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

Referring to fig. 1, 3, 4 and 5, in the present embodiment, when the elastic energy storage assembly 30 abuts against the main valve element 21, a water flow gap is formed between the elastic energy storage assembly 30 and the main valve element 21, so that the side of the main valve element 21 facing the elastic energy storage assembly 30 can be acted by water pressure. By providing a water flow gap, on the one hand, water flow can flow to the side of main spool 21 facing elastic energy storage assembly 30 to apply water pressure to main spool 21 to cause main spool 21 to move under the influence of the incoming water pressure in a direction to close main port 15; on the other hand, the problem that the main valve opening 15 cannot be closed in the process of storing water in the accumulator by the main valve element 21 due to the fact that the elastic energy storage assembly 30 is attached to the main valve element 21 and the elastic energy storage assembly 30 attracts and moves the main valve element 21 in the direction away from the main valve opening 15 when moving under the action of water pressure is avoided.

Specifically, when the flow passage 14 is opened, the side of the main valve element 21 facing away from the energy storage chamber 13 is subjected to water pressure, and when the water pressure applied to the side of the main valve element 21 facing away from the energy storage chamber 13 is equal to or less than the water pressure applied to the side of the main valve element 21 located in the energy storage chamber 13, the main valve element 21 can automatically open the main valve port 15 by an external force acting on the main valve element 21 or by the self-weight of the main valve element 21. The specific manner of causing main valve element 21 to open main valve port 15 may be designed as desired and is not limited to the above-described embodiment.

When the overflow passage 14 is opened, the resultant of the elastic force exerted by the first elastic member 22 on the main valve element 21 and the water pressure exerted on the side of the main valve element 21 facing away from the accumulator 13 is greater than the water pressure exerted on the side of the main valve element 21 on the accumulator 13, and the main valve element 21 opens the main valve port 15 under the action of the external force provided by the first elastic member 22. The main valve spool 21 automatically opens the main valve port 15 by the elastic external force provided by the first elastic member 22, which is more reliable.

The body 10 further comprises a bottom cover 10c, an opening is formed at one end, away from the water outlet cavity 16, of the energy storage cavity 13, the main control valve 20 and the elastic energy storage assembly 30 are installed in the energy storage cavity 13 through the opening, a guide rod 211 (the guide rod 211 is used for guiding the up-and-down movement of the main valve core 21) arranged on the main valve core 21 extends upwards from the main valve port 15 to the water outlet cavity 16, and the bottom cover 10c covers the opening, so that the energy storage device is assembled more conveniently, and the assembly efficiency is improved.

In this embodiment, the first elastic member 22, the second elastic member 32, and the fourth elastic member 42 are compression springs. And the elastic force of the second elastic member 32 is greater than that of the first elastic member 22, and the elastic force of the fourth elastic member 42 exerted on the sub-valve 41 is greater than the water pressure of the inflow water of the water inlet 11 on the sub-valve 41.

In use, in an initial state, water is not supplied to the water inlet 11, and at this time, the main valve element 21 closes the main valve port 15, and the overflow passage 14 is in a closed state. Referring to fig. 3 to 5, when the water inlet 11 begins to fill, water flows into the energy storage chamber 13 against the elastic force of the elastic energy storage assembly 30, and the main valve element 21 keeps closing the main valve port 15 against the elastic force of the first elastic element 22 under the action of the water pressure in the energy storage chamber 13. As the water flow continuously enters 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 downwards and compress the second elastic element 32 for storing energy. In this process, the auxiliary valve body 41 of the auxiliary control valve 40 keeps closing the auxiliary valve port 141 under the elastic force of the fourth elastic member 42 (at this time, the elastic force of the fourth elastic member 42 on the auxiliary valve body 41 is greater than the water pressure of the water flow on the auxiliary valve body 41), and the overflow channel 14 keeps a closed state, so that the water flow of the water inlet 11 cannot flow to the water outlet 12 through the overflow channel 14.

When water flows in the water outlet cavity 16, one side of the main valve element 21, which is back to the energy storage cavity 13, is subjected to water pressure, at this time, the resultant force of the elastic force exerted on the main valve element 21 by the first elastic element 22 and the water pressure exerted on one side of the main valve element 21, which is back to the energy storage cavity 13, is greater than the water pressure exerted on one side of the main valve element 21, which is located on the energy storage device 13, taking the direction of fig. 6 as an example, the main valve element 21 moves downward and opens the main valve port 15, at this time, the water in the energy storage cavity 13 is discharged from the main 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.

After the water in the energy storage chamber 13 is discharged, since 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 main valve element 21 so that the main valve element 21 can be located at a position for closing the main valve port 15 against the elastic force of the first elastic element 22. Meanwhile, after the elastic energy storage assembly 30 is reset, the contact of the swing rod 51 of the transmission mechanism 50 is lost, and the auxiliary valve core 41 is reset under the action of the fourth elastic element and closes the auxiliary valve port 141, so that the energy storage device is restored to the initial state.
