Description

Technical Field

[0001] This utility model relates to the field of battery energy storage technology, and in particular to an energy storage container. Background Technology

[0002] With the widespread application of new energy sources in various fields, battery energy storage is also facing new challenges. Energy storage containers integrate energy storage units (lithium batteries) into containers and are used in distributed generation, grid peak shaving and valley filling systems in different scenarios (industrial parks, manufacturing plants), realizing the rapid integration and rapid deployment of energy storage equipment.

[0003] In related technologies, batteries and electrical cabinets are integrated within shipping containers. To improve cooling during battery operation, partitions divide the container's interior into battery and control compartments. Air conditioning is installed in the battery compartment for cooling. However, due to space limitations and the need to optimize cooling equipment utilization, air conditioning or other cooling devices are typically not installed in the control room. In hot weather, the external temperature rapidly increases the temperature inside the control compartment. Since the electrical cabinets in the control room also continuously generate heat during operation, the combined effect of the external temperature and the equipment itself leads to a high internal temperature. Simply using the ventilation holes on the container is insufficient for timely cooling. Excessive heat can easily cause short circuits and equipment malfunctions.

[0004] Therefore, a new type of energy storage container is needed to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model aims to provide an energy storage container that can promptly cool the control room.

[0006] The technical solution of this utility model is implemented as follows:

[0007] An energy storage container includes a container body with a storage space, a liftable partition dividing the storage space into two independent spaces: a battery compartment and a control compartment, a temperature sensor installed in the control compartment, and a main controller. The battery compartment is equipped with a battery rack, a fire extinguishing device, and a cooling device. The control compartment is equipped with an electrical cabinet. The liftable partition includes a roller shutter mechanism fixedly installed on the top of the container body and a roller shutter door that is wound around the roller shutter mechanism and moved up and down by the roller shutter mechanism. The temperature sensor is installed in the control compartment and is connected to the main controller. The main controller controls the operation of the roller shutter mechanism based on the signal emitted by the temperature sensor.

[0008] Preferably, a support frame is installed inside the housing, and the roller blind mechanism includes a mounting base fixedly installed on the support frame, a driver with a driving external gear fixedly installed on the mounting base, a driven external gear fixed on the mounting base and meshing with the driving external gear, and a rotating shaft axially installed on the driven external gear. A roller is sleeved on the rotating shaft, and the roller blind is wound on the roller.

[0009] Preferably, the roller shutter door consists of multiple movable door panels connected in series.

[0010] Preferably, the roller shutter door is a single piece and is made of flexible fireproof and heat-insulating material.

[0011] Preferably, the bottom of the housing has a recessed groove facing the ground, the groove being opened along the direction of the roller, and when the roller shutter door is lowered to the ground of the housing, the bottom edge of the roller shutter door is embedded in the groove.

[0012] Preferably, the driver is a motor.

[0013] Preferably, the cooling device includes a cooler and a ventilation duct connected to the cooler, the ventilation duct being positioned directly above the battery box frame.

[0014] Preferably, the fire extinguishing device is a cabinet-type heptafluoropropane gas fire extinguishing device.

[0015] Preferably, the battery box frame includes a support frame and a plurality of brackets and trays mounted on the support frame, wherein the battery box containing the battery is supported on the trays and detachably mounted on the brackets.

[0016] Preferably, the bottom of the battery box has two opposite sides connected to a positioning edge, and the bracket has a limiting groove, into which the positioning edge is inserted.

[0017] The energy storage container provided in this embodiment of the utility model uses the temperature sensor to detect the temperature inside the compartment in real time and sends the monitoring information to the main controller. The main controller can then control the roller shutter mechanism to drive the roller shutter door to move up and down based on the monitoring information. This allows the partition to open when the temperature in the control compartment is too high, allowing cool air from the battery compartment to enter the control compartment and promptly lower the temperature. This reduces the risk of short circuits due to high temperatures, effectively lowers the failure rate of the control compartment, does not affect the independence of the two compartments, and eliminates the need for additional refrigeration equipment, thus controlling costs.

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please refer to the following: Figures 1 to 3 This utility model provides an energy storage container. The energy storage container includes a container body 1 with accommodating space, a liftable partition 4 dividing the accommodating space into two independent spaces: a battery compartment 2 and a control compartment 3, a temperature sensor 5 installed in the control compartment 3, and a main controller 6. The battery compartment 2 is equipped with a battery rack 7, a fire extinguishing device 8, and a cooling device 9. The control compartment 3 is equipped with an electrical cabinet 13 for controlling various sensors, alarms, fire detectors, temperature detectors, indicator lights, fire extinguishing devices 8, and cooling devices 9 within the battery compartment 2. The main controller 6 is installed in the electrical cabinet 13. The liftable partition 4 includes a roller shutter mechanism 41 fixedly installed on the top of the container body 1 and a roller shutter door 43 that is wound around the roller shutter mechanism 41 and moved up and down by the roller shutter mechanism 41. The temperature sensor is installed in the control compartment 3 and connected to the main controller 6. The main controller 6 controls the roller shutter mechanism 41 to operate based on the signal emitted by the temperature sensor.

[0026] Under normal conditions, the liftable partition 4 divides the internal space of the housing 1 into a battery compartment 2 and a control compartment 3. The two compartments are independent of each other and do not affect each other. The battery compartment 2 is equipped with a cooling device 9 to reduce heat generated by the batteries during operation. Therefore, the temperature inside the compartment is monitored in real time by the temperature sensor 5. The temperature sensor 5 monitors the temperature inside the control compartment 3 and sends the monitoring information to the main controller 6. When the temperature exceeds a set value, the main controller 6 controls the roller shutter mechanism 41 to move, and the roller shutter door 43 rises and opens, allowing cool air from the battery compartment 2 to enter the control compartment 3. The temperature of the control compartment 3 is lowered. When the temperature drops to the preset temperature, the main controller 6 controls the roller shutter mechanism 41 to move, and the roller shutter door 43 descends and closes, isolating the space into two independent spaces. In this way, under normal circumstances, the two compartments are independent of each other and do not affect each other. Only when the temperature in the control compartment 3 is too high, the cold space in the battery compartment 2 is used to cool the control compartment 3 in time, reducing the occurrence of short circuits and other phenomena caused by high temperature, effectively reducing the failure rate of the control compartment 3, without affecting the independence of the two compartments, and without the need to add new refrigeration equipment, thus controlling costs.

[0027] It should be noted that, in order to meet the needs of cargo handling, maintenance and other operations, the liftable partition 4 between the two compartments sometimes needs to be opened. Therefore, a main control box is also installed on the outside of the container. The main control box is electrically connected to the liftable partition 4 and is also used to control the up and down movement of the liftable partition 4.

[0028] Please refer to the following: Figure 3 and Figure 4 Specifically, in this embodiment, a support frame 101 is installed inside the housing 1. The roller shutter mechanism 41 includes a mounting base 411 fixedly installed on the support frame, a driver 414 with a driving external gear 413 fixedly installed on the mounting base 411, a driven external gear 415 fixedly installed on the mounting base 411 and meshing with the driving external gear 413, and a rotating shaft 417 axially installed on the driven external gear 415. A roller 419 is sleeved on the rotating shaft 417, and the roller shutter 43 is wound around the roller 419. The support frame 101 is assembled from structural steel. The mounting base 411 is bolted to the support frame 101. The driver drives the driving external gear 413 to rotate, which in turn drives the driven external gear 415 to rotate. The rotating shaft on the driven external gear 415 rotates accordingly, causing the roller installed on the rotating shaft 417 to rotate as well. The roller shutter moves up and down due to the forward and reverse rotation of the roller.

[0029] Specifically, the roller shutter door 43 is composed of multiple movable door panels 431 connected in series. One end of the roller shutter door 43 is fixedly connected to the outer periphery of the roller drum 419, and the other end is a free end. It is worth noting that each door panel is formed by pressing together two thin steel plates filled with polyurethane foam, with the edges of adjacent panels interlocking to form a single unit. Polyurethane foam has good thermal insulation, weather resistance, and chemical stability, and is widely applicable.

[0030] like Figure 1 As shown, in addition, a recessed groove 102 is provided at the bottom of the box 1, which is located towards the ground. The groove 102 is opened along the direction of the roller 419. When the roller shutter 43 is lowered to the ground of the box 1, the bottom edge of the roller shutter 43 is embedded in the groove 102 to better block the two spaces, and the partitioning effect of the roller shutter 43 is better.

[0031] In another embodiment, the roller shutter door 43 is a single piece and is made of flexible fireproof and heat-insulating material. Specifically, the roller shutter door 43 is a single panel made of a flexible fireproof and heat-insulating material, such as fiberglass insulation cotton, asbestos, fire-resistant fiber, etc.

[0032] Specifically, the driver 414 is a motor. The driving external gear 413 is mounted on the output shaft of the motor and is driven to rotate by the motor. The driven external gear 415 rotates under the drive of the driving external gear 413, thereby driving the rotating shaft to rotate. The roller 419 rotates under the drive of the rotating shaft 417. In this way, the roller shutter door 43 can move up and down.

[0033] Specifically, in this embodiment, the cooling device 9 includes a cooler 91 and a ventilation duct 93 connected to the cooler 91. The ventilation duct delivers cool air to various locations. The ventilation duct 93 is positioned directly above the battery rack 7 to blow maximum cool air onto the battery, thereby rapidly reducing the battery's operating temperature. More specifically, the cooler is an air conditioner.

[0034] Specifically, in this embodiment, the fire extinguishing device 8 is a cabinet-type heptafluoropropane gas fire extinguishing device. This device 8 consists of an extinguishing agent cylinder assembly, an electromagnetic drive device, a metal hose, a signal feedback device, nozzles, and a cabinet. It eliminates the need for extinguishing agent delivery pipelines and a dedicated storage room; the extinguishing agent cylinder assembly is placed inside the cabinet. Heptafluoropropane primarily uses chemical extinguishing agents, while also possessing physical extinguishing properties. It is colorless, odorless, clean, non-conductive, and does not pollute the protected object. It will not damage property or precision equipment and has no destructive effect on the atmospheric ozone layer (ODP value is zero), thus meeting environmental protection requirements.

[0035] Please see Figure 5 and Figure 6The battery box frame 7 includes a support frame 71 and several brackets 73 and trays 75 mounted on the support frame 71. The battery box 10 containing batteries is supported on the trays 75 and detachably mounted on the brackets 73. Multiple battery boxes can be placed on the support frame 71 to improve the convenience of large energy storage needs.

[0036] Furthermore, the bottom of the battery box 10 has two opposite sides connected to a positioning edge 103, and the bracket 73 has a limiting groove 731. The positioning edge 103 is inserted into the limiting groove 731 so that the battery box and the bracket 73 form a detachable connection. In this way, the number of battery boxes installed on the battery rack can be flexibly changed according to the energy storage needs, making it more convenient to use.

[0037] The energy storage container provided in this embodiment of the utility model uses the temperature sensor to detect the temperature inside the compartment in real time and sends the monitoring information to the main controller 6. The main controller 6 can then control the roller shutter mechanism 41 to drive the roller shutter door 43 to move up and down based on the monitoring information. This allows the partition to open when the temperature in the control compartment 3 is too high, allowing cool air from the battery compartment 2 to enter the control compartment 3 and reduce the temperature of the control compartment 3 in time. This reduces the occurrence of short circuits caused by high temperatures, effectively lowers the failure rate of the control compartment 3, does not affect the independence of the two compartments, and does not require the addition of new refrigeration equipment, thus controlling costs.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
