The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0072] like Figures 1 to 6 As shown, the present invention provides an AC-to-DC conversion leakage energy storage device, including a chassis 1, in which an energy storage battery 2 and a rectifier 3 are arranged, the rectifier 3 is electrically connected to an external AC power supply, and the rectifier 3 is also electrically connected to the energy storage battery 2 through a leakage protection structure, and the rectifier 3 is used to convert AC power into DC power and transmit it to the energy storage battery 2 through the leakage protection structure; the rectifier 3 is electrically connected to a leakage alarm structure, and the energy storage battery 2 can be electrically connected to the leakage alarm structure to supply power, and the leakage alarm structure enters an alarm state when sensing that the electric energy in the rectifier 3 is reduced; the leakage alarm structure and the leakage protection structure are connected through an electric control drive structure, and when the leakage alarm structure is in an alarm state, the leakage alarm structure drives the leakage protection structure through the electric control drive structure to disconnect the electrical connection between the rectifier 3 and the energy storage battery 2 to protect the energy storage battery 2.

[0073] The present invention solves the problem that during the use of the energy storage device, the alternating current and direct current cannot be flexibly converted according to the use requirements, resulting in poor adaptation effect of the energy storage device. At the same time, if the energy storage device has leakage during use, it cannot be discovered in time, which affects the safety of the use of the energy storage device.

[0074] In the present invention, the rectifier converts the introduced alternating current into direct current, and can flexibly convert the alternating current and direct current; when leakage occurs, the electric energy inside the rectifier 3 decreases, and the leakage alarm structure electrically connected to the rectifier 3 enters an alarm state when sensing the decrease in the electric energy inside the rectifier 3; at the same time, the leakage alarm structure drives the leakage protection structure through the electric control drive structure to disconnect the electrical connection between the rectifier 3 and the energy storage battery 2 to protect the energy storage battery 2; the leakage alarm structure and the leakage protection structure can be linked to quickly respond to leakage faults and give an alarm in time, so that the fault can be discovered in time and the safety of the use of the energy storage equipment is improved.

[0075] Further, if Figure 2 As shown, in order to maintain the stability of the energy storage battery 2 inside the chassis 1 and reduce the impact of external vibration on the energy storage battery 2, a support structure for shock-proofing and supporting the energy storage battery 2 is provided in the chassis 1.

[0076] Further, if Figure 2 , Figure 4As shown, the leakage alarm structure includes a fixed cylinder 9, an electromagnet 10, a magnetic block 12 and an alarm 13. The fixed cylinder 9 is fixedly connected to the top of the inner wall of the chassis 1, and a cylinder cavity is arranged in the fixed cylinder 9; the electromagnet 10 is fixedly arranged at the bottom of the cylinder cavity, and the electromagnet 10 is electrically connected to the rectifier 3; the magnetic block 12 is arranged in the cylinder cavity, and the magnetic block 12 can slide up and down under the action of the electromagnet 10; the electromagnet 10 generates an electromagnetic force according to the electric energy transmitted by the rectifier 3, and the magnetic block 12 can float in the cylinder cavity under the action of the electromagnetic force. When the electric energy transmitted by the rectifier 3 is reduced, the magnetism of the electromagnet 10 is reduced, and it is difficult to push the magnetic block 12 to float, and the magnetic block 12 will move down;

[0077] like Figure 1 , Figure 2 As shown, the alarm 13 is arranged at the top of the chassis 1 and is exposed and visible, and the power connection end 1301 of the alarm extends to the bottom end of the magnetic block 12; the electromagnet 10 is provided with a power connection end 1401 electrically connected to the energy storage battery 2. When the magnetic block 12 falls onto the electromagnet 10, the alarm 13 is electrically connected to the energy storage battery 2 through the power connection end 1301 and the power connection end 1401 of the alarm to power on and alarm.

[0078] Further, if Figure 2 , Figure 4 As shown, the bottom end of the magnetic block 12 is also provided with a first electric drive terminal 1501 electrically connected to the power terminal 1301 of the alarm; the electromagnet 10 is provided with a second electric drive terminal 1502 insulated and isolated from the power connection terminal 1401, and the second electric drive terminal 1502 is electrically connected to the electric control drive structure; the magnetic block 12 falls onto the electromagnet 10, and the power terminal 1301 of the alarm is electrically connected to the power connection terminal 1401, while the electric control drive structure is electrically connected to the energy storage battery 2 through the second electric drive terminal 1502, the first electric drive terminal 1501, the power terminal 1301 of the alarm, and the power connection terminal 1401 to energize and drive the leakage protection structure to disconnect.

[0079] Further, if Figure 2 As shown, the electromagnet 10 is electrically connected to the rectifier 3 through the first wire 11; the energy storage battery 2 is electrically connected to the second wire 14, and the end of the second wire 14 away from the energy storage battery 2 extends to the top of the electromagnet 10 to form a power connection end 1401.

[0080] If leakage occurs during use of the energy storage device, the electric energy inside the rectifier 3 is reduced, causing the electric energy of the electromagnet 10 transmitted by the first wire 11 to be reduced. The magnetism of the electromagnet 10 is reduced, and it is difficult to push the magnetic block 12 to float. The magnetic block 12 moves down and falls on the electromagnet 10. The power connection terminal 1301 of the alarm is electrically connected to the power connection terminal 1401. At the same time, the electric control drive structure is electrically connected through the second electric drive terminal 1502, the first electric drive terminal 1501, the power connection terminal 1301 of the alarm, and the power connection terminal 1401. The energy storage battery 2 powers on the alarm 13 and the electric control drive structure through the second wire 14. The alarm 13 can enable people around it to discover it in time. The electric control drive structure is powered on to drive the leakage protection structure to disconnect, and the energy storage battery 2 is protected to prevent damage to the energy storage battery 2.

[0081] Further, if Figure 2 , Figure 3 As shown, the leakage protection structure includes an insert block 6, a socket 7 and a connector 8. The socket 7 is fixedly connected to the top of the energy storage battery 2, and a through accommodating cavity is arranged in the socket 7; the connector 8 is slidably arranged at the lower part of the accommodating cavity, the connector 8 is electrically connected to the energy storage battery 2, the connector 8 is connected to the electric control drive structure, and the connector 8 can slide up and down under the drive of the electric control drive structure; the insert block 6 is detachably inserted in the upper part of the accommodating cavity, the insert block 6 is electrically connected to the rectifier 3, specifically, the insert block 6 is electrically connected to the rectifier 3 through the connecting line 5; the connector 8 can move upward to be electrically connected to the insert block 6 to conduct the rectifier 3 and the energy storage battery 2, or the connector 8 moves downward away from the insert block 6 to disconnect the electrical connection between the rectifier 3 and the energy storage battery 2.

[0082] During normal use, the rectifier 3 can convert the AC power introduced by the connecting wire 4 into DC power, and the DC power is introduced into the energy storage battery 2 through the connecting wire 5, the plug block 6 and the connector 8, so that DC and AC power can be flexibly converted.

[0083] Furthermore, an opening is provided on one side of the accommodating cavity, and one side of the joint 8 is hinged to an electric control driving structure; the electric control driving structure drives the joint 8 to slide up and down along the accommodating cavity.

[0084] Further, if Figure 2 , Figure 3 As shown, the electric control drive structure includes an electric push rod 15, a connecting seat 16 and a push rod 17. The electric push rod 15 includes a push rod housing fixedly connected to the top of the energy storage battery 2, and a piston rod is slidably inserted into the push rod housing. The wiring terminals of the electric push rod (including the aforementioned second electric drive wiring terminal 1502 and the first electric drive wiring terminal 1501) can be electrically connected to the energy storage battery 2 through the leakage alarm structure; the end of the piston rod is fixedly connected to the aforementioned connecting seat 16, and the first end of the push rod 17 is hinged on the connecting seat 16. The first end of the push rod 17 extends to the inside of the opening and is hinged to the side wall of the joint 8.

[0085] After the electric push rod 15 is powered on, it pushes the push rod 17 to move and drive the connector 8 to slide downward along the inner wall of the socket 7, so that the circuit between the rectifier 3 and the energy storage battery 2 is disconnected, and the energy storage battery 2 can be protected to prevent the energy storage battery 2 from being damaged.

[0086] Further, if Figure 2 , Figure 3 As shown, in order to keep the plug 6 stable inside the socket 7, a groove is provided on the outer wall of the plug 6, and a flat fixing rod 19 is provided in the groove. A clamping plate 20 and a torsion spring 21 are movably sleeved on the rod wall of the fixing rod 19. One end of the torsion spring 21 is fixedly connected to the clamping plate 20, and the other end of the torsion spring 21 is fixedly connected to the plug 6. A clamping groove is provided on the side wall of the accommodating cavity at a position corresponding to the clamping plate 20, and the clamping groove is a fan-shaped groove; the clamping plate 20 can be swung to clamp in the clamping groove or swung out of the clamping groove and recovered into the groove.

[0089] After the plug 6 is inserted into the accommodating cavity in the socket 7, the torsion spring 21 can push the card plate 20 to extend into the card slot, so that the plug 6 can be kept stable inside the socket 7. When the plug 6 needs to be removed later, the pull ring 24 can pull the second pull rope 23 to move, and the movement of the second pull rope 23 can drive the card plate 20 to shrink into the groove when the first pull rope 22 moves, so that the plug 6 can be pulled out from the inside of the socket 7 in time, which is convenient for adjustment and maintenance.

[0090] Further, if Figure 2 , Figure 3 As shown, a sealing ring 18 is provided above the opening in the accommodating cavity, and the bottom of the plug block 6 can be pressed tightly against the upper surface of the sealing ring 18. The sealing ring 18 can improve the tightness when the plug block 6 and the connector 8 are in contact.

[0091] Further, if Figure 2 , Figure 5 As shown, the support structure includes a buffer connection structure that can buffer the vertical and horizontal shaking of the energy storage battery 2, and two buffer connection structures are respectively arranged between the two sides of the energy storage battery 2 and the chassis 1 in an upper and lower symmetrical manner.

[0092] Further, if Figure 2 , Figure 5 As shown, each buffer connection structure includes a connection cylinder 27, a connecting rod 29, a guide block 31, and a guide rail 30. The first end of the connection cylinder 27 is hinged on the side wall of the energy storage battery 2. The first end of the connecting rod 29 slides into the connection cylinder 27 from the second end of the connection cylinder 27 in a sealed manner. A retaining ring 33 is provided at the second end of the connection cylinder 27 to block the connection cylinder 27. The connecting rod 29 passes through the retaining ring 33 and enters the connection cylinder 27. The second end of the connecting rod 29 is hinged to the guide block 31. The guide rail 30 is vertically provided on the side wall of the chassis 1. The guide block 31 is slidably sleeved on the guide rail 30. Specifically, the guide block 31 is provided as a trapezoidal block. The inner wall of the guide rail 30 matches the guide block 31. The structure of the guide block 31 is as shown in FIG. Figure 6 shown.

[0093] Further, if Figure 5 As shown, a piston 28 is slidably disposed in the connecting cylinder 27 , a first end of the piston 28 is fixedly connected to a first end of a connecting rod 29 , and a spring 32 is disposed between a second end of the piston 28 and a first end of the connecting cylinder 27 .

[0094] Further, if Figure 5 As shown, a damping washer 34 is fixedly connected to the side wall of the piston 28 , and the side wall of the damping washer 34 is fitted to the inner wall of the connecting tube 27 .

[0095] Further, if Figure 5 As shown, a fixing seat 26 is fixedly connected to the side wall of the energy storage battery 2 at a position where each buffer connection structure is hinged.

[0096] Further, if Figure 5 As shown, a metal reinforcement frame 25 is fixedly connected to the inner wall of the chassis 1 , and each guide rail 30 is fixedly connected to the inner wall of the metal reinforcement frame 25 .

[0097] When the device is in use, if the outside of the case 1 shakes, the gap between the energy storage battery 2 and the case 1 changes, which will push the guide block 31 to slide along the inner wall of the guide rail 30, thereby improving the stability of the energy storage battery 2. If the guide block 31 is tightly set inside the guide rail 30 and continues to shake, in order to prevent the energy storage battery 2 from being damaged, the guide block 31 will push the connecting rod 29 and the piston 28 to move, compress the spring 32, and play a certain role in buffering and releasing force, further improving the stability of the energy storage battery 2, preventing the energy storage battery 2 from being damaged, and maintaining the stability of the energy storage battery 2 inside the case 1, thereby reducing the impact of external vibration on the energy storage battery 2.

[0098] From the above we can see:

[0099] (1) In the present invention, the rectifier 3 converts the AC power introduced by the connecting wire 4 into DC power, and can flexibly convert the AC and DC power. The electric energy inside the rectifier 3 is reduced, the electric energy transmitted by the first wire 11 to the electromagnet 10 is reduced, the magnetism of the electromagnet 10 is reduced, and the magnetic block 12 moves downward to make the power connection terminal 1301 of the alarm contact with the connection terminal of the electric push rod. The energy storage battery 2 uses the second wire 14 to power the alarm 13 and the electric control drive structure (electric push rod). The alarm 13 sounds an alarm so that people around can find it in time. After the electric push rod 15 is powered on, it will push the push rod 17 to move and drive the connector 8 to slide downward along the inner wall of the socket 7. The circuit between the rectifier 3 and the energy storage battery 2 is disconnected, and the energy storage battery 2 is protected to prevent the energy storage battery 2 from being damaged.

[0100] (2) In the present invention, after the plug-in block 6 is plugged into the interior of the socket 7, the torsion spring 21 can push the card plate 20 to extend into the interior of the card slot, so that the plug-in block 6 remains stable inside the socket 7. When the plug-in block 6 needs to be removed later, pulling the pull ring 24 can pull the second pull rope 23 to move. When the second pull rope 23 moves, it can drive the first pull rope 22 to move. The card plate 20 shrinks to the inside of the groove, and the plug-in block 6 can be pulled out from the interior of the socket 7 in time, which is convenient for adjustment and maintenance.

[0101] (3) In the present invention, the change in the gap between the energy storage battery 2 and the chassis 1 will push the guide block 31 to slide along the inner wall of the guide rail 30, which can improve the stability of the energy storage battery 2; after the guide block 31 is tightly set inside the guide rail 30, if it continues to shake, in order to prevent the energy storage battery 2 from being damaged, the guide block 31 will push the connecting rod 29 and the piston 28 to move, so that the spring 32 is compressed, which can play a certain buffering and force-relieving role, further improve the stability of the energy storage battery 2, prevent the energy storage battery 2 from being damaged, and improve the stability of the energy storage battery 2 inside the chassis 1.

[0102] Example

[0103] The working principle of the AC-DC conversion leakage energy storage device of the present invention is as follows:

[0104] The rectifier 3 converts the AC power introduced by the connecting wire 4 into DC power, and the DC power is transmitted to the energy storage battery 2 through the leakage protection structure, which can improve the flexibility of the use of the energy storage device and flexibly convert the AC power and DC power;

[0105] When leakage occurs, the electric energy inside the rectifier 3 will decrease, so that the electric energy delivered to the electromagnet 10 by the first wire 11 will decrease, the magnetism of the electromagnet 10 will decrease, and it will be difficult to push the magnetic block 12 to float. The magnetic block 12 moves down and falls on the electromagnet 10, and the power connection terminal 1301 of the alarm is electrically connected to the power connection terminal 1401. The energy storage battery 2 powers on the alarm 13 and the electric control drive structure through the second wire 14, and the alarm 13 can enable the surrounding personnel to find it in time; at the same time, the electric push rod 15 of the electric control drive structure is electrically connected through the second electric drive terminal 1502, the first electric drive terminal 1501, the power connection terminal 1301 of the alarm, and the power connection terminal 1401. After the electric push rod 15 is energized, it pushes the push rod 17 to move and drives the connector 8 to slide down along the inner wall of the socket 7, and the connector 8 leaves the plug 6, and the circuit between the rectifier 3 and the energy storage battery 2 is disconnected, and the energy storage battery 2 is protected to prevent the energy storage battery 2 from being damaged.

[0106] As described above, the AC-DC conversion leakage energy storage device of the present invention has the following beneficial effects:

[0107] In the present invention, the rectifier converts the introduced alternating current into direct current, and can flexibly convert the alternating current and direct current; when leakage occurs, the electric energy inside the rectifier is reduced, and the leakage alarm structure electrically connected to the rectifier enters an alarm state when sensing the reduction in the electric energy inside the rectifier; at the same time, the leakage alarm structure drives the leakage protection structure through the electric control drive structure to disconnect the electrical connection between the rectifier and the energy storage battery to protect the energy storage battery; the leakage alarm structure and the leakage protection structure can be linked to quickly respond to leakage faults and give an alarm in time, so that the fault can be discovered in time and the safety of the use of the energy storage device is improved.

[0108] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
