Description

Technical Field

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

[0002] Compared with conventional power generation resources, renewable energy power generation has strong randomness and volatility. Large-scale renewable energy grid connection will have a great impact on the safe operation of the power system, leading to difficulties in balancing power. New power systems require more flexible resources to solve the problems of wind and solar power consumption and volatility. Energy storage systems can realize the time and space transfer of energy and enhance the flexibility of the system. In particular, the development of new energy storage represented by electrochemistry and hydrogen storage has accelerated significantly in recent years.

[0003] With the large-scale development of new energy power, containerized energy storage systems are usually used to store large amounts of electricity for backup. However, the existing containerized energy storage systems often use integrated energy storage components installed in the entire container. This can easily cause the entire structure of the energy storage components to catch fire when an electrical fire occurs, increasing the difficulty and risk of fire extinguishing. Summary of the invention

[0004] In view of this, the present invention provides a new energy storage device to address the deficiencies in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a new energy storage device, comprising an isolation box, a battery box and a control box arranged in sequence, a partition is arranged in the battery box, a plurality of first straps are arranged on both sides of the partition, a plurality of second straps are arranged on both sides of the battery box, the second straps correspond to the positions of the first straps, battery modules are placed on the first and second straps, a first connecting plate is arranged at the junction of the battery box and the control box, a plurality of conductive seats are arranged on the first connecting plate, the conductive seats are correspondingly connected to the conductive heads of the battery modules, and a battery pushing component is arranged on the outer side of each conductive seat; a second connecting plate is arranged at the junction of the isolation box and the battery box, a plurality of through holes for the battery modules to pass through are provided on the second connecting plate, and a cooling and fire extinguishing component is arranged in the isolation box.

[0006] Furthermore, an energy storage inverter and a thermal management system are arranged in the control box. The thermal management system includes a controller and a temperature sensor. The temperature sensor is integrated in the battery module, and the temperature sensor is connected to the controller signal.

[0007] Furthermore, the battery pushing component includes an electromagnet, an electromagnet controller and a spring. There are two electromagnets, which are respectively arranged on both sides of the conductive seat. Both electromagnets are signal-connected to the electromagnet controller arranged in the control box. There are two springs, which are respectively arranged between the electromagnet and the conductive seat. Magnet blocks are arranged on both sides of the conductive head of the battery module.

[0008] Furthermore, the electromagnet controller is connected to the controller signal.

[0009] Furthermore, the first strap and the second strap are both provided with grooves, a plurality of rollers are arranged in the grooves, and the upper sides of the rollers are higher than the grooves.

[0010] Furthermore, the cooling and fire extinguishing component includes a carbon dioxide storage tank, a conduit, a solenoid valve and a nozzle. The carbon dioxide storage tank is located on the top of the isolation box, the main pipe of the conduit is connected to the carbon dioxide storage tank, and the solenoid valve is arranged on the main pipe. The two branch pipes of the conduit enter from the top surface of the isolation box, and the ends of the two branch pipes are connected to the nozzle, and the solenoid valve is connected to the controller signal.

[0011] Furthermore, a blocking plate is hingedly connected to the upper side of each of the plurality of through holes of the second connecting plate, the size of the blocking plate is larger than the through hole, and the blocking plate is located on a side close to the isolation box.

[0012] Furthermore, when one of the battery modules is overheated, the controller sends information to the electromagnet controller, and the electromagnet controller controls the change of the magnetic pole of the electromagnet to have the same magnetic properties as the magnet block on the battery module. Under the repulsive force of the magnet and the action of the spring, the battery module passes through the through hole into the isolation box. At the same time, the solenoid valve is opened under the control of the controller to spray carbon dioxide into the isolation box to cool it down and extinguish the fire.

[0013] Furthermore, a circular hole is opened on one side of the battery box, and an exhaust fan is installed in the circular hole through a flange structure. A plurality of air inlet holes are opened on the other side of the battery box, and each of the air inlet holes is connected to a curved pipe, and a filter is arranged in the curved pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The new energy storage device of the present invention adopts an isolation box, a battery box and a control box which are arranged in sequence. The battery box is divided into two chambers by a partition. The chamber is supported by two side panels to facilitate heat dissipation. A conductive seat is arranged on the first connecting plate between the battery box and the control box for docking with the conductive head on the battery module. The conductive head and the conductive seat are directly in contact and conductive, rather than plugged in, to facilitate subsequent separation of the battery modules. A plurality of through holes are arranged on the second connecting plate between the battery box and the isolation box to allow the abnormally heated battery module to pass through and enter the isolation box. When the battery module is abnormally heated, the controller of the thermal management system sends information to the electromagnet controller to control the electromagnet to have opposite magnetic poles and repel the magnet on the battery module. In addition, under the joint action of the spring, the battery module moves along the plurality of rollers on the panel to the isolation box, and the abnormally heated battery module is cooled and extinguished by the cooling and fire extinguishing components in the isolation box, thereby protecting other normal battery modules.

[0016] 2. In the new energy storage device of the present invention, the battery pushing component adopts an electromagnet as a driving component. When placing the battery module, the battery module is pushed into the battery box along the plate roller, the magnet block is attracted and fixed by the electromagnet, and the spring is compressed. When a battery module heats up abnormally, the magnetic pole of the electromagnet is reversed, and the battery module is quickly pushed out and isolated in time under the action of the repulsive force and the spring.

[0017] 3. The new energy storage device of the present invention adopts a carbon dioxide fire extinguishing method for cooling and extinguishing components. When the battery module is abnormally overheated, the controller controls the solenoid valve to open, and the liquid carbon dioxide is sprayed out and vaporized immediately, which quickly cools down and reduces the oxygen concentration in the isolation box. It has good flame retardancy and will not pollute or corrode the inside of the isolation box, making it easy to maintain.

[0018] 4. In the new energy storage device of the present invention, a blocking plate is hingedly connected to the upper side of the through hole of the second connecting plate. The plate is larger than the through hole and is located on the side close to the isolation box. When the battery module has an abnormal temperature, it can smoothly enter the isolation box. Moreover, after carbon dioxide is sprayed in the isolation box, the blocking plate can effectively block the through hole under the action of pressure to prevent carbon dioxide from entering the battery box and affecting the normal battery module.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0025] Example 1

[0027] The isolation box 1 is hinged to the battery box 2 on one side and detachably connected to the battery box 2 on the other side by bolts. When installing or replacing the battery module, the isolation box 1 is rotated to the side of the battery box 2 for operation.

[0028] A circular hole is provided on one side of the battery box 2, and an exhaust fan 11 is installed in the circular hole through a flange structure. A plurality of air inlet holes are provided on the other side of the battery box 2, and each of the air inlet holes is connected to a curved pipe 12, and a filter is provided in the curved pipe 12.

[0029] The control box 3 is provided with an energy storage converter and a thermal management system. The thermal management system includes a controller and a temperature sensor. The temperature sensor is integrated in the battery module, and the temperature sensor is connected to the controller signal.

[0030] The battery pushing component includes an electromagnet 13, an electromagnet controller and a spring 14. There are two electromagnets 13, which are respectively arranged on both sides of the conductive seat 8. The two electromagnets 13 are signal-connected to the electromagnet controller arranged in the control box. There are two springs 14, which are respectively arranged between the electromagnet 13 and the conductive seat 8. Magnet blocks are arranged on both sides of the conductive head of the battery module.

[0031] The electromagnet controller is connected to the controller signal.

[0032] The first strap 5 and the second strap 6 are both provided with grooves, in which a plurality of rollers 15 are arranged, and the upper sides of the rollers 15 are higher than the grooves.

[0033] The cooling and fire extinguishing components include a carbon dioxide storage tank 16, a conduit 17, a solenoid valve 18 and a nozzle. The carbon dioxide storage tank 16 is located at the top of the isolation box 1. The main pipe of the conduit 17 is connected to the carbon dioxide storage tank 16, and the solenoid valve 18 is arranged on the main pipe. The two branch pipes of the conduit 17 enter from the top surface of the isolation box 1, and the ends of the two branch pipes are connected to the nozzles. The solenoid valve 18 is connected to the controller signal.

[0034] A blocking plate is hingedly connected to the upper side of each of the plurality of through holes of the second connecting plate 9 . The size of the blocking plate is larger than the through hole, and the blocking plate is located on a side close to the isolation box 1 .

[0035] When the new energy storage device of the embodiment of the present invention is used, the isolation box 1 is first rotated to one side of the battery box 2, and then the battery module is placed on the multiple rollers 15 on the two side boards, the battery module is pushed into the battery box 2, and the conductive head of the battery module is contacted and connected with the conductive seat 8 on the first connecting plate 7. At this time, the magnet block on the battery module is attracted and fixed to the electromagnet 13 on the first connecting plate 7, and the spring 14 is in a compressed state, and then the isolation box 1 is rotated to dock with the battery box 2 and fixed by bolts; during use, when one of the battery modules is overheated, the controller sends information to the electromagnet controller, and the electromagnet controller controls the change of the magnetic pole of the electromagnet 13 to be the same as the magnet block on the battery module.

[0036] When the present invention is in use, the electromagnet 13 is in a normally open state. Since the present application is an energy storage device, technical personnel in this industry, taking into account the energy storage needs, usually do not think of using structures such as electromagnets that consume additional electricity to drive the overheated battery module. However, the inventor found in actual work that the power generation of new energy is usually in surplus, and this surplus electricity is used for the operation and maintenance of the energy storage device to achieve full utilization of energy.
