Description

Technical Field

[0001] This utility model belongs to the field of battery box technology, and specifically relates to a modular energy storage battery box that can be quickly disassembled and assembled. Background Technology

[0002] Energy storage battery boxes are commonly used energy storage containers in power plants. Through battery charging and discharging operations, they play a role in peak shaving and valley filling, improving power quality, serving as backup power sources, regulating frequencies, and participating in the construction of smart grids.

[0003] Common energy storage battery boxes cool the batteries using coolant. Specifically, cooling pipes are laid inside the battery housing. After the housing is installed, coolant is introduced into the cooling pipes to reduce the operating temperature of the batteries inside the housing.

[0004] However, when it is necessary to remove the casing inside the battery box, the coolant in the cooling pipes needs to be drained before disassembly. However, the cooling pipes on the battery box share a common coolant circulation system, which makes the disassembly and assembly inefficient and also affects the cooling effect of batteries in other casings.

[0005] Therefore, a modular energy storage battery enclosure that can be quickly assembled and disassembled is needed. Summary of the Invention

[0006] The purpose of this invention is to provide a modular energy storage battery housing that can be quickly disassembled and assembled, thereby enabling the batteries inside the housing to be quickly removed.

[0016] Compared with existing technologies, this utility model has the following beneficial effects: This invention features a first pipe on the outer casing and a second pipe inside the casing. After the outer casing is installed, the second valve is closed and the first valve is opened, allowing coolant to circulate only in the first pipe to cool the battery inside. When it is necessary to remove a specific casing from the battery box, the second valve is opened. At this time, each port of the tee formed by the first and second pipes is open. Since the resistance in the second pipe is less than that in the first pipe, the second pipe becomes the coolant circulation path. Opening the pressure relief valve allows coolant in the first pipe to enter the second pipe, thus draining the coolant from the first pipe. The outer casing can then be removed to complete the removal process. The coolant circulation does not stop during this removal process, thus not affecting the cooling of batteries in other casings.

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

[0025] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: This utility model provides a modular battery box that can be quickly disassembled and assembled. The modular energy storage battery box 1 includes: a box body 1, an outer shell 2, a support plate 3, a first pipeline 4, and a second pipeline 5. The support plate 3 is disposed inside the box body 1, and the outer shell 2 is disposed on the support plate 3. The outer shell 2 is used to load batteries. The first pipeline 4 is disposed inside the outer shell 2, and the second pipeline 5 is disposed on the bottom surface of the support plate 3. The first pipeline 4 and the second pipeline 5 are detachably connected. A first valve 7 is disposed at the connection between the first pipeline and the second pipeline, and a second valve 6 is disposed inside the second pipeline. The resistance inside the second pipeline 5 is less than the resistance inside the first pipeline 4. A pressure relief valve is disposed on the first pipeline 4.

[0026] Among them, reference Figure 1 , Figure 2 as well as Figure 3 The connection between the first pipe 4 and the second pipe 5 forms a T-junction. The second pipe 5 extends outward from its connection with the first pipe 4. The inlet and outlet of the battery box's coolant circulation system are connected to the second pipe 5. After the outer casing 2 is installed, the second valve 6 is closed and the first valve 7 is opened. The coolant circulates only in the first pipe 4 to cool the batteries inside the outer casing 2. When it is necessary to remove a particular outer casing 2 from the battery box, the second valve 6 is opened. At this time, each port of the T-junction formed by the first pipe 4 and the second pipe 5 is open. Since the resistance in the second pipe 5 is less than the resistance in the first pipe 4, the second pipe 5 becomes the coolant circulation pipe. The pressure relief valve is opened, and the coolant on the first pipe 4 enters the second pipe, thereby draining the coolant from the first pipe 4. At this point, the outer casing 2 can be removed to complete the removal work. The coolant circulation does not stop during this removal process, thus not affecting the cooling of the batteries inside other outer casings 2.

[0027] In this case, the resistance in the second pipe 5 can be less than the resistance in the first pipe 4 by having a diameter in the second pipe 5 that is larger than the diameter in the first pipe 4.

[0028] It should be noted that the second valve 6 and the pressure relief valve can be electronically controlled. When it is necessary to disassemble the outer casing 2, the second valve 6 and the pressure relief valve can be opened in advance. When the staff arrives on site, they only need to disconnect the connection between the first pipeline 4 and the second pipeline 5 to remove the outer casing 2.

[0029] In one embodiment of this utility model, the first inlet end of the first pipe 4 is connected to the second inlet end of the second pipe 5, and the first outlet end of the first pipe 4 is connected to the second outlet end of the second pipe 5. The second valve 6 is disposed at the second inlet end. This arrangement allows the interfaces of the first pipe 4 and the second pipe 5 to be concentrated on one side of the housing 2, facilitating disassembly by the user.

[0030] In one embodiment of the present invention, the connection between the first pipeline and the second pipeline includes an arc portion 401 of the first pipeline 4 and a connecting portion 501 of the second pipeline 5; the arc portion 401 is respectively disposed on the first liquid inlet and the first liquid outlet, and the connecting portion 501 is respectively connected above the second liquid inlet and the second liquid outlet, and the first pipeline 4 and the second pipeline 5 are connected through the connecting portion 501.

[0031] Among them, the arc-shaped structure of the arc portion 401 is more conducive to the flow of coolant in the pipe than the right-angle structure. The connecting portion 501 can be a vertical structure, which is beneficial for user installation. Alternatively, it can adopt an inclined pipe structure, which can reduce the pressure difference in the tee pipe compared to the vertical pipe structure, thus facilitating the circulation of coolant in the second pipe 5.

[0032] In one embodiment of this invention, the first valve 7 is disposed within the connecting portion 501. This arrangement allows the connecting portion 501 to be sealed even after the cooling water inside the first pipe 4 has been discharged and the outer casing 2 has been removed, achieving two goals at once.

[0033] In one embodiment of the present invention, the first pipeline 4 and the second pipeline 5 are detachably connected by a threaded connection, a nut 402 is provided on the arc portion 401, and a thread is provided on the connecting portion 501.

[0034] In one embodiment of the present invention, the first valve 7 includes a piston 705, a valve body 704, a spring 703, a first bracket 701, and a second bracket 702. The valve body 704 is mounted on the inner wall of the connecting part 501 and is annular. One end of the piston 705 is mounted on the inner ring of the valve body 704, and the other end is connected to the second bracket 702. The spring 703 is disposed between the second bracket 702 and the valve body 704. The first bracket 701 is disposed on the nut 402, and the second bracket 702 has a dredging hole 702a.

[0035] Reference Figure 4The cooperation between valve body 704 and piston 705 enables the opening and closing of connection 501. Under normal circumstances, piston 705 cooperates with valve body 704 via spring 703, forming a blockage of connection 501. First bracket 701, mounted on the inner wall of nut, can be cylindrical or strip-shaped. When nut is threaded into connection 501, first bracket 701 moves downwards with nut, pushing second bracket 702, causing piston 705 to move downwards, thus opening connection 501. Coolant enters arc portion 401 through unblocking hole 702a. When housing 2 is removed, nut moves upwards, and piston 705 re-engages with valve body 704, blocking connection 501.

[0036] In one embodiment of this utility model, the connection end between the arcuate portion 401 and the connecting portion 501 is located below the bottom surface of the outer casing 2. This arrangement allows the outer casing 2 to be horizontally assembled and disassembled within the battery compartment, improving efficiency.

[0037] In one embodiment of the present invention, the outer shell 2 includes a first shell 201 and a second shell 202; an accommodating space is formed between the first shell 201 and the second shell 202, and a first pipeline 4 is disposed in the second shell 202, with the liquid inlet and liquid outlet at both ends respectively disposed on the front end face of the second shell 202.

[0038] In one embodiment of this utility model, guide members 9 are provided on both sides of the first housing 201 and the second housing 202, and a guide groove 8 that cooperates with the guide member 9 is provided inside the housing 1. The cooperation between the guide member 9 and the guide groove 8 makes it easier to align the arc portion 401 and the connecting portion 501 during installation, and also facilitates the disassembly and assembly of the outer shell 2.

[0039] Reference Figure 5 In one embodiment of this utility model, a traction groove 801 is provided on the guide groove 8. The width of the traction groove 801 is greater than that of the guide groove 8, which makes it easier for the user to align the guide 9 with the guide groove 8 during installation, thus facilitating installation.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
