Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, in particular to energy storage equipment and electrical equipment. Background Art

[0002] A novel energy storage equipment fire extinguishing system with a publication number of "CN214860743U" in the prior art includes a cabinet, a fixing plate, a fixing ring, a perfluorohexanone fire extinguisher, a storage box, a support plate and a battery pack. The cabinet is fixedly connected with a support plate at equal intervals, and the inner wall of the cabinet is slidably plugged with a storage box at equal intervals. Battery packs are evenly arranged inside the storage box. A fixing plate is fixedly connected to one side of the cabinet, and a perfluorohexanone fire extinguisher is arranged on the top of the fixing plate. The output end of the perfluorohexanone fire extinguisher is connected to the corresponding side of the cabinet through a pipeline. The device can separate the battery packs inside the cabinet from each other through a protective mechanism to avoid rapid spread of flames when a fire occurs, and also allow the battery pack to have a certain shock-absorbing protection in the cabinet to extend its service life. It is more convenient to place and remove the battery pack in the storage box. The cabinet is equipped with multiple fire prevention equipment, which can extinguish the flame in time when a fire occurs, reduce the spread of the fire, and reduce losses.

[0003] However, the above-mentioned new energy storage equipment fire extinguishing system still has obvious defects during use: the above-mentioned device installs each battery pack separately inside the cabinet. Although it has a certain isolation effect on adjacent battery packs, the fire is relatively fierce when a battery pack catches fire. The violent combustion generated by itself cannot ensure that adjacent battery packs are not affected. The installation structure of the above-mentioned battery pack is a common battery pack installation structure in the prior art, and the fire extinguishing devices installed therein are all passive fire extinguishing devices, and the fire extinguishing effect of this type of battery pack is limited, making it difficult to ensure the safety of the entire energy storage equipment.

Several fire-fighting nozzles arranged in an array are connected to the fire-fighting tank body arranged inside the fire-fighting cylinder body through electromagnetic valves respectively.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-9 , the present invention provides a technical solution:

[0033] Embodiment 1:

[0034] An energy storage device, comprising:

[0035] A rotating cylinder 1, which is driven by a rotating drive mechanism to perform a preset α° reciprocating rotation around its own axis, and a plurality of energy storage partitions 2 are arranged on the rotating cylinder 1, and each layer of the energy storage partitions 2 is divided into a plurality of energy storage compartments 4 by partitions 3;

[0036] A plurality of energy storage battery boxes 5, which are distributed in a ring array in the rotating cylinder 1, and the energy storage battery boxes 5 are slidably installed inside the energy storage cabin 4, and a plurality of temperature sensors 6 are attached to the surface of the energy storage battery boxes 5;

[0037] A plurality of battery release mechanisms, wherein the plurality of battery release mechanisms are arranged in a one-to-one correspondence in the energy storage compartment 4. When any temperature sensor 6 on the surface of the energy storage battery box 5 stored in the energy storage compartment 4 exceeds a set threshold, the battery release mechanism pushes the energy storage battery box 5 to pop out and leave the energy storage compartment 4; and

[0038] The fire recovery cabin 7 is arranged on the side of the rotating cylinder 1. A delivery port 8 is opened on the side of the fire recovery cabin 7. The energy storage cabin 4 cooperates with the delivery port 8 in sequence during the reciprocating rotation of the rotating cylinder 1. The battery release mechanism performs the delivery movement only when the energy storage cabin 4 cooperates with the delivery port 8 in a one-to-one manner.

[0039] In this embodiment, the rotating cylinder 1 is used as a storage mechanism for the energy storage battery box 5. It is driven by the rotating drive mechanism to reciprocate 180° around its own rotation axis, thereby ensuring that all positions of the rotating cylinder 1 can cooperate with the fire recovery cabin 7. The energy storage battery box 5 is installed in the energy storage cabin 4 of the rotating cylinder 1 in a pull-out installation manner. It is movably matched with the guide wheel 22 installed in the energy storage cabin 4 through the slide rail grooves 21 opened on both sides of the bottom. An electrical interface groove 23 is also opened above the energy storage battery box 5, and an electrical connection seat 24 is provided in the energy storage cabin 4. When the energy storage battery box 5 enters the energy storage cabin 4, the energy storage battery box 5 is connected to the energy storage cabin 4. The electrical connection seat 24 at the rear of the compartment 4 is electrically connected to the electrical interface slot 23. A partition 3 is provided between each energy storage compartment 4 to separate each energy storage battery box 5. When a fire occurs in one of the energy storage battery boxes 5, the impact on the adjacent energy storage compartment 4 can be reduced. Furthermore, in order to ensure accurate monitoring of the energy storage battery box 5, temperature sensors 6 are attached to multiple positions on the surface of the energy storage battery box 5. The temperature sensor 6 is connected to the PLC control module 29 to transmit the temperature condition of the surface of the energy storage battery box 5 to the PLC control module 29. The PLC control module 29 sets the alarm threshold of the temperature sensor 6. When the temperature threshold is exceeded, the rotating cylinder 1 rotates under the drive of the rotating drive mechanism, so that the energy storage cabin 4 with abnormal temperature rotates to the side of the fire recovery cabin 7, so that the energy storage cabin 4 reaches the delivery port 8. At this time, the energy storage battery box 5 with abnormal temperature is pushed into the fire recovery cabin 7 through the battery release mechanism. In this way, when an abnormality occurs in the energy storage battery box 5, the component can be quickly separated from the other energy storage battery boxes 5 of the rotating cylinder 1, thereby effectively ensuring the overall safety of the energy storage device, and further In order to improve the utilization efficiency of the fire recovery cabin 7, there are 2-3 rotating cylinders 1, which are arranged in a circular array on the side of the fire recovery cabin 7. The side of the fire recovery cabin 7 is provided with fire recovery cabins 7 whose number is the same as that of the rotating cylinders 1. The rotating cylinders 1 arranged in a circular array are combined with the fire recovery cabins 7 to form an energy storage unit 9. The energy storage units 9 are arranged in a matrix in the energy storage station. Maintenance channels are arranged between adjacent rows of energy storage units 9. Maintenance personnel can enter the energy storage station through the maintenance channels to complete daily inspection, patrol and maintenance of the energy storage device.

[0040] Embodiment 2:

[0041] In this embodiment, the bottom of the rotating cylinder 1 is rotatably arranged on the base 10, and the rotating cylinder 1 and the base 10 are provided with upper and lower matching roller grooves 11 on the opposite sides, and a plurality of matching rollers 12 are arranged in a circular array in the roller groove 11. The rotating drive mechanism that drives the rotating cylinder 1 to perform reciprocating rotational motion is a stepper motor 13, and the stepper motor 13 is fixedly mounted on the base 10. The stepper motor 13 cooperates with the gear groove provided at the bottom of the rotating cylinder 1 through a driving gear 15 fixedly mounted on the driving shaft. The rotation of the stepper motor 13 drives the driving gear to rotate and then drives the rotating cylinder 1 to perform reciprocating rotational motion, wherein the base 10 is a concrete base, and the rotating cylinder 1 and the base 10 The roller grooves 11 are provided with a plurality of matching rollers 12 in a rotating array, and the rotation of the rotating cylinder 1 is supported by the matching rollers 12. When rotational motion is required, the stepper motor 13 drives the driving gear 15 to rotate by rotation, thereby driving the rotating cylinder 1 to perform reciprocating rotational motion.

[0042] Embodiment three:

[0043] A fire-fighting cylinder 16 is also fixedly installed at the axis of the base 10, and a fire-fighting passage 17 for the fire-fighting cylinder 16 to pass through is opened on the rotating cylinder 1. A fire-fighting mechanism 18 is hoisted inside the fire-fighting cylinder 16, and the fire-fighting mechanism 18 includes a fire-fighting nozzle 19 arranged in an array on one side of the delivery port 8 facing the fire-fighting recovery cabin 7. The fire-fighting cylinder 16 and the rotating cylinder 1 are both provided with a fire-fighting passage 20 that cooperates with the fire-fighting nozzle 19 on one side of the fire-fighting cylinder 17. The fire-fighting passage 20 penetrates the rotating cylinder 1 and extends into the energy storage cabin 4. Several fire-fighting nozzles 19 arranged in an array are connected to the fire-fighting tank body arranged inside the fire-fighting cylinder 16 through electromagnetic valves. When the battery release mechanism inside the energy storage cabin 4 works, the fire-fighting nozzle 19 connected to the energy storage cabin 4 is opened under the control of the electromagnetic valve, and the fire-fighting medium stored in the fire-fighting tank body is sprayed into the energy storage cabin 4 with abnormal temperature through the fire-fighting nozzle 19.

[0044] In this embodiment, in order to further ensure the safety of the rotating cylinder 1, a fire-fighting cylinder 16 is fixedly installed at the axis of the base 10, and a fire-fighting mechanism 18 is installed in the fire-fighting cylinder 16. The fire-fighting mechanism 18 is a commonly used arrangement in the prior art, that is, the tank storing the fire-fighting medium is connected to the fire-fighting nozzle 19 through a pipeline via an electromagnetic valve. When there is an energy storage battery box 5 with abnormal temperature in the energy storage cabin 4, when the rotation of the rotating cylinder 1 reaches the delivery port 8, the battery release mechanism pushes the energy storage battery box 5 into the fire-fighting recovery cabin 7, and the PLC control module 29 controls the corresponding electromagnetic valve to open. At this time, the high-pressure fire-fighting medium in the tank passes through the fire-fighting nozzle 19 and the fire-fighting channel 20 and finally enters the corresponding energy storage cabin 4, thereby timely extinguishing the internal open fire and preventing the adjacent energy storage cabin 4 from being implicated.

[0045] Embodiment 4:

[0046] The battery release mechanism that pushes the energy storage battery box 5 to leave the energy storage cabin 4 includes a force storage spring 25. The force storage spring 25 is fixedly connected to a push plate 26 on one side of the energy storage battery box 5. A traction rope 27 is connected to the push plate 26. The traction rope 27 is in contact with the fusible heating wire 28. A number of temperature sensors 6 are electrically connected to a PLC control module 29. When the temperature sensor 6 exceeds a set threshold, the PLC control module 29 issues a working instruction to the stepper motor 13 to drive the rotating cylinder 1 to rotate, so that the energy storage cabin 4 with abnormal temperature rotates and moves to the side of the delivery port 8. When the energy storage cabin 4 with abnormal temperature arrives at the delivery port 8, the PLC control module 29 sends a fusing instruction to the fusible heating wire 28. After the traction rope 27 is melted, the force storage spring 25 releases its elastic force to drive the push plate 26 to accelerate toward the side of the energy storage battery box 5. The accelerated movement of the push plate 26 pushes the energy storage battery box 5 to pop out of the energy storage cabin 4 and fall into the fire recovery cabin 7.

[0047] The rotating cylinder 1 outside the several energy storage cabins 4 is provided with a first circuit connection contact 14, and the fire recovery cabin 7 is provided with a second circuit connection contact 30 that cooperates with the first circuit connection contact 14 above and below. During the rotation of the rotating cylinder 1, the first circuit connection contact 14 of each energy storage cabin 4 is alternately coordinated with the second circuit connection contact 30 to conduct the circuit of the fusible heating wire 28. When the internal temperature of the energy storage cabin 4 where the circuit is located is abnormal, the fusing instruction sent by the PLC control module 29 reaches the fusible heating wire 28 when the first circuit connection contact 14 of the energy storage cabin 4 cooperates with the second circuit connection contact 30. After the fusible heating wire 28 is melted, the energy storage battery box 5 enters the fire recovery cabin 7.

[0048] In this embodiment, the battery release mechanism adopts a spring energy storage method. The storage spring 25 is pulled by the traction rope 27 to maintain a compressed state under normal conditions. When the temperature inside the energy storage cabin 4 is abnormal, the PLC control module 29 sends a command to drive the rotating cylinder 1 to rotate. When the corresponding energy storage cabin 4 reaches the delivery port 8, the first circuit connection contact 14 and the second circuit connection contact 30 cooperate to turn on the circuit where the fuse heating wire 28 is located. Refer to the attached manual Figure 8 When the first circuit connection contact 14 and the second circuit connection contact 30 are in a non-contact state, the fuse heating wire 28 is in an open circuit state. In this way, it is ensured that the battery release mechanism must work after the rotating cylinder 1 reaches a specific position, further ensuring that the energy storage battery box 5 can accurately enter the fire recovery cabin 7. When the fuse heating wire 28 is melted, the storage spring 25 quickly pushes the push plate 26 to move to one side of the energy storage battery box 5, and the energy storage battery box 5 then slides into the fire recovery cabin 7 through the delivery port 8 under the action of inertia, thereby completing the rapid release of the energy storage battery box 5.

[0049] An electrical device adopts the above energy storage device.
