Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a battery cluster and a rail locomotive. Background Art

[0002] With the rapid development of the new energy industry, new energy has been deeply favored by end users due to its advantages of environmental protection and energy saving. The rail locomotive industry, which was originally powered by petroleum energy, is also gradually undergoing electrification transformation. When designing locomotive battery systems, industry designers generally refer to industrial and commercial energy storage solutions. Since industrial and commercial energy storage is generally used in remote areas far away from people, it can reduce damage to the surrounding areas when safety accidents occur. The locomotive battery system is generally arranged in the locomotive carriage. If the locomotive has thermal runaway during driving, it will affect the safety of the entire vehicle and endanger the life of the driver. How to improve the safety performance of the battery system is a technical problem faced by industry technicians.

[0003] At present, when designing locomotive battery systems, industry designers generally use auxiliary fire protection systems to provide safety protection for batteries. These auxiliary fire protection systems need to monitor the status of the battery through monitoring modules. Once the battery has thermal runaway, it will release fire extinguishing media to achieve the fire extinguishing function of the battery system. However, due to the limited amount of these fire extinguishing media, once these battery boxes have thermal runaway and spread, it is difficult to cover all the battery boxes in the locomotive compartment. Therefore, how to prevent the thermal runaway of the battery box from spreading and reduce the fire extinguishing area has become a technical problem that the industry urgently needs to solve. Utility Model Content

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 6 The embodiment of the present application provides a battery cluster 100, including a shell 10 and an adapter plate 20. One side of the shell 10 has an opening. The shell 10 is provided with a plurality of storage compartments connected to the opening so that the battery box can be accommodated in the storage compartment through the opening. The adapter plate 20 is detachably arranged at the opening so that the shell 10 is in a closed state. The first adapter 21 and the second adapter 22 are respectively arranged on opposite sides of the adapter plate 20 so that the battery box can be connected to an external device through the first adapter 21 and the second adapter 22. The first adapter 21 and the second adapter 22 are connected by a hot melt. The battery cluster 100 can solve the problem of thermal runaway propagation in the battery box in the prior art, thereby reducing the risk of thermal runaway propagation.

[0033] It should be noted that if Figure 1 As shown, the battery cluster 100 includes a shell 10, one side of the shell 10 has an opening, and a plurality of storage compartments connected to the opening are arranged in the shell 10, so that the battery box can be accommodated in the storage compartment through the opening. On this basis, the battery cluster 100 also includes an adapter plate 20, which is detachably arranged at the opening to keep the shell 10 in a closed state, so that the shell 10 and the adapter plate 20 can jointly protect the battery box accommodated in the storage compartment. Among them, in order to ensure that the battery box can work normally and be cooled by liquid cooling, a first adapter 21 and a second adapter 22 are respectively arranged on the opposite sides of the adapter plate 20 (that is, the outer side of the adapter plate 20 away from the battery box and the inner side of the adapter plate 20 close to the battery box), so that the battery box can be connected to the external device through the first adapter 21 and the second adapter 22. The first adapter 21 and the second adapter 22 are connected by a hot melt. As a result, once a battery box has thermal runaway, the temperature in the storage compartment is too high, causing the hot melt to melt, thereby preventing the heat in the storage compartment from being transferred to the outside of the storage compartment through the hot melt, thereby preventing the thermal runaway of the battery box from spreading, and then avoiding affecting all battery boxes in the entire locomotive compartment.

[0034] Optionally, the adapter plate 20 includes multiple layers of glass substrates arranged at intervals, the circumferential edges of two adjacent layers of glass substrates are fixed and sealed, and a vacuum cavity is formed between the two adjacent layers of glass substrates. Figure 4 and Figure 5As shown, in this embodiment, the adapter plate 20 includes two layers of glass substrates with fireproof and explosion-proof properties that are spaced apart. The circumferential edges of the two layers of glass substrates can be fixed by sealant to achieve a sealed connection between the circumferential edges of the two layers of glass substrates. Before the circumferential edges of the two layers of glass substrates are completely sealed, a small hole can be reserved to perform a vacuum operation between the two layers of glass substrates through the small hole. After the vacuum operation is completed, the reserved small hole is filled with sealant to form a vacuum cavity between the two adjacent layers of glass substrates, thereby reducing the mutual transfer of heat between the inner and outer sides of the adapter plate 20 through the vacuum cavity. In addition, since the glass substrate is transparent, the operator can also observe the thermal runaway state of the battery box inside the adapter plate 20 through the glass substrate, so as to facilitate further processing, such as injecting a fire extinguishing medium or spraying high-pressure water for fire extinguishing.

[0035] Alternatively, if Figure 4 and Figure 5 As shown, in this embodiment, when the first adapter 21 and the second adapter 22 are matched high and low pressure connectors, the hot melt component is a hot melt wire; when the first adapter 21 and the second adapter 22 are matched pipelines, the hot melt component is a hot melt pipe. It should be understood that the number of the first adapter 21 and the second adapter 22 is multiple, and the multiple first adapters 21 and the multiple second adapters 22 are arranged in a one-to-one correspondence. For example, Figure 4 and Figure 5 As shown, in the present embodiment, one pair of the first adapter 21 and the second adapter 22 are matching high-voltage connectors, and another pair of the first adapter 21 and the second adapter 22 are matching low-voltage connectors, and the first adapter 21 and the second adapter 22 are connected by a thermal fuse to ensure the normal operation of the battery box, thereby providing power supply for the rail locomotive; one pair of the first adapter 21 and the second adapter 22 are matching water inlet pipes, and another pair of the first adapter 21 and the second adapter 22 are matching water outlet pipes, and the first adapter 21 and the second adapter 22 are connected by a hot melt pipe to ensure that the battery box can be connected to the liquid cooling system for cooling, thereby reducing the risk of thermal runaway of the battery box.

[0036] Alternatively, if Figure 4 and Figure 5 As shown, in this embodiment, a fire nozzle 23 is also provided on the adapter plate 20, so that the fire extinguishing medium can be sprayed into the battery box through the fire nozzle 23, thereby achieving fire extinguishing; and / or, a pressure relief valve 24 is also provided on the adapter plate 20, so that when the internal pressure of the battery box is too high, the gas can be sprayed out of the battery box through the pressure relief valve 24.

[0037] Alternatively, if Figure 2As shown, in the present embodiment, a barrier plate 30 is provided between two adjacent storage bins to separate and isolate the plurality of storage bins through the barrier plate 30 to prevent thermal runaway of a battery box in one of the storage bins from spreading to battery boxes in other storage bins. The barrier plate 30 is filled with fireproof and heat-insulating materials to further prevent the high temperature in the storage bin with thermal runaway from being transferred to other storage bins. The shell 10 is filled with fireproof and heat-insulating materials to further prevent the high temperature in the battery cluster 100 with thermal runaway from being transferred to other battery clusters 100.

[0038] Alternatively, if Figure 2 As described above, in this embodiment, each storage compartment is provided with a limiter 40, and the limiter 40 is used to guide the battery box to be stored in the storage compartment. For example, there are two limiters 40, so that the range of movement of the battery box when it is stored in the storage compartment is limited by the two limiters 40, and there is a certain gap between the limiter 40 and the side wall of the storage compartment to prevent the battery box from rubbing against the side wall of the storage compartment when it is stored in the storage compartment through the opening, thereby affecting the service life of the battery box.

[0039] Alternatively, if Figure 2 As shown, in the present embodiment, a rolling member 50 is provided on the side of the limiting member 40 close to the battery box, and the rolling member 50 is used for rolling contact with the battery box. In this way, when the battery box is placed in the accommodating compartment through the opening, the side wall of the battery box will roll relative to the rolling member 50. By converting the sliding friction between the battery box and the limiting member 40 into the rolling friction between the battery box and the rolling member 50, the friction resistance between the battery box and the limiting member 40 can be reduced, thereby improving the assembly efficiency.

[0040] Alternatively, if Figure 3 As shown, in this embodiment, the housing 10 includes a circumferentially closed side panel 11 and a rear sealing plate 12 disposed on a side of the side panel 11 away from the adapter plate 20, as shown in FIG. Figure 6 As shown, in this embodiment, a protrusion 121 is provided on the rear sealing plate 12, and the protrusion 121 is used to cooperate with the back of the battery box. Among them, the side panel 11 can be a complete whole, or it can be a left sealing plate, a bottom sealing plate, a right sealing plate and a top sealing plate 111 connected in sequence. Similarly, the left sealing plate and the right sealing plate can be a complete whole, or they can be a plurality of separate sealing plates directly fixed on the bracket of the battery cluster 100, thereby forming the shell 10 of the battery cluster 100 together. In this way, the shell 10 can reduce the effect of heat transfer from the battery box to the left, bottom, right, top and back, and combined with the effect of reducing the heat transfer from the battery box to the front through the adapter plate 20, it can effectively prevent the occurrence of thermal runaway.

[0041] Alternatively, if Figures 1 to 3As shown, a plurality of reinforcing beams 13 are arranged in the shell 10, wherein the reinforcing beams 13 include at least one of a transverse beam, a longitudinal beam and a side beam to improve the structural strength of the battery cluster 100, and the transverse beams and the longitudinal beams can also realize the effective division of a plurality of accommodating chambers, so as to divide the overall space in the shell 10 into a plurality of accommodating chambers, and then with the use of the blocking plate 30, the plurality of accommodating chambers can be separated independently. In addition, the mutual cooperation between the above-mentioned reinforcing beams 13 can form a bracket of the battery cluster 100, and then the mounting blocks 60 are arranged on each reinforcing beam 13, which can also facilitate the fixed installation between the adapter plate 20 and the sealing plate in each direction and the reinforcing beam 13, thereby forming a battery cluster 100 in a fully enclosed state.

[0042] And / or, a plurality of fixing members 14 are provided along the circumferential edge of the top of the housing 10, for example, Figures 1 to 3 As shown, in this embodiment, the fixing member 14 is a lifting ring to connect the top of the battery cluster 100 to the locomotive compartment; and / or, a plurality of supporting members 15 are provided along the circumferential edge of the bottom of the housing 10, for example, Figures 1 to 3 As shown, in this embodiment, the support member 15 is a support foot to improve the reliability of fixing the bottom of the battery cluster 100 to the locomotive compartment. Through the cooperation between the fixing member 14 and the support member 15, the influence of the vibration of the locomotive on the battery cluster 100 can be reduced.

[0043] The embodiment of the present application further provides a railway locomotive, comprising the above-mentioned battery cluster 100. Since the structure and beneficial effects of the battery cluster 100 have been described in detail in the above-mentioned embodiment, they will not be described again here.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
