Description

Technical Field

[0001] This application relates to the field of fire protection technology for energy storage containers, and in particular to an easily removable in-cabin detector. Background Technology

[0002] Energy storage containers utilize shipping containers as an excellent carrier to provide uninterrupted power to various devices. Each container houses several battery packs for energy storage. To enhance safety, energy storage containers are equipped with fire suppression systems. These systems include detectors installed within each battery pack to monitor gas levels and temperature, determining if a fire is detected and triggering a series of fire-fighting measures.

[0003] Common in-pack detectors are installed inside the battery pack. Due to the limited lifespan of these detectors, they need to be inspected and replaced periodically to ensure proper operation. Since these detectors are typically installed inside the battery pack, inspecting or replacing them requires opening the battery pack. After the inspection or replacement, the battery pack's protection level also needs to be retested. This entire process is overly cumbersome and severely impacts the operator's efficiency in inspecting or replacing detectors. Utility Model Content

[0004] To improve the efficiency of operators in inspecting or replacing detectors, this application provides an in-bag detector that is easy to disassemble.

[0005] The bag-mounted detector provided in this application adopts the following technical solution: A removable in-pack detector includes a base plate detachably mounted outside a battery pack. The base plate is detachably provided with a detection circuit module for detecting target gas concentration and / or ambient temperature and / or smoke concentration. The detection circuit module extends into the battery pack, and the base plate and the battery pack are sealed together.

[0006] By adopting the above technical solution, the substrate can be detachably installed outside the battery pack, and the detection circuit module can be plugged into the battery pack to achieve the effect of in-pack detection. With this installation method, the operator does not need to open the battery pack when replacing or repairing the detector, reducing the complicated process of battery pack protection detection, which helps to improve the efficiency of the operator in replacing or repairing the detector.

[0007] Optionally, the substrate may be detachably equipped with a protective cover for enclosing the detection circuit module.

[0008] By adopting the above technical solution, a protective cover is set up to cover the detection circuit module, reducing the problem of damage to the detection circuit module caused by external forces.

[0009] Optionally, the protective cover is provided with several through holes.

[0010] By adopting the above technical solution, through holes are set on the protective cover so that the detector can detect the target gas concentration, ambient temperature and smoke concentration inside the battery pack.

[0011] Optionally, the substrate is provided with a plurality of ear plates on the side facing the protective cover, and the protective cover is connected to the ear plates by threaded parts.

[0012] By adopting the above technical solution, the operator attaches the protective cover to the detection circuit module and then connects the protective cover to the ear plate through the threaded parts, so that the protective cover can be detachably connected to the base plate, so that the operator can inspect and repair the detector's detection circuit module.

[0013] Optionally, multiple ear plates are provided, and each ear plate is arranged around the contour of the opening end of the protective cover and can be supported on the side wall of the protective cover.

[0014] By adopting the above technical solution, multiple ear plates are arranged to form the outline of the opening end of the protective cover, so that the protective cover can be positioned on the base plate, making it convenient for the operator to connect the ear plates to the protective cover through threaded parts.

[0015] Optionally, the base plate is provided with a hook plate, the protective cover is provided with a slot for the hook plate to be inserted, the base plate is also provided with an elastic plate, the elastic plate is provided with a locking block, and the protective cover is provided with a locking groove for the locking block to be engaged.

[0016] By adopting the above technical solution, when the operator installs the protective cover on the substrate, first insert the hook of the hook plate into the slot of the protective cover, and then the operator flips the side of the protective cover away from the slot toward the substrate so that the card block is engaged in the card slot, thereby realizing the detachable connection of the protective cover on the substrate.

[0017] Optionally, the card block has an inclined surface on the side facing away from the substrate, the inclined surface being used to guide the card block so that the card block can be inserted into the card slot.

[0018] By adopting the above technical solution, an inclined surface is set on the card block, which guides the card block so that it can slide into the card slot, thereby realizing the rapid installation of the protective cover on the base plate.

[0019] Optionally, a sealing gasket is fitted onto the protective cover, and the substrate can press the sealing gasket tightly onto the battery pack.

[0020] By adopting the above technical solution, the substrate presses the sealing gasket tightly onto the outer wall of the battery pack, thereby achieving a sealing effect on the opening of the battery pack.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The base plate is detachably mounted outside the battery pack, allowing the detection circuit module to be plugged into the battery pack, achieving the effect of in-pack detection. This eliminates the need for operators to open the battery pack when replacing or repairing detectors, reducing complex processes such as battery pack protection detection and improving the efficiency of operators when replacing or repairing detectors. 2. The operator can detach the protective cover and install it on the base plate, which makes it convenient for the operator to inspect and repair the detector's detection circuit module.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. Example 1

[0030] This application discloses an easily detachable in-bag detector. For example... Figure 1 and Figure 2 The easily detachable internal detector includes a substrate 2, which can be a plate of any shape. In this embodiment, the substrate 2 is a square plate.

[0031] like Figure 2 and Figure 3The substrate 2 can be detachably mounted on the battery pack 1. The substrate 2 can be fixedly connected to the battery pack 1 by bolts or screws, or by clips. In this embodiment, a locking screw 21 is provided through the substrate 2 and is threaded to the outer wall of the battery pack 1, so that the substrate 2 can be detachably mounted on the battery pack 1.

[0032] like Figure 3 and Figure 4 The battery pack 1 has an opening 11 corresponding to the position of the substrate 2, and the substrate 2 can completely cover the opening 11. A detection circuit module 22 is installed on one side of the substrate 2, and the detection circuit module 22 passes through the opening 11 and extends into the battery pack 1. The detection circuit module 22 can detect the concentration of target gas and / or ambient temperature and / or smoke concentration inside the battery pack 1, where the target gas includes flammable and explosive gases such as carbon monoxide and hydrogen. Cables are connected to the circuit module 22, and a waterproof connector is installed on the side of the substrate 2 opposite to the circuit module 22. The cable passes through the waterproof connector and extends out of the battery pack 1 for connection to controllers and other devices. A protective cover 24 has an annular sealing gasket 23 on the side of the substrate 2 facing the battery pack 1. The substrate 2 presses the sealing gasket 23 tightly against the outer wall of the battery pack 1 to achieve a sealing effect between the substrate 2 and the opening 11 of the battery pack 1.

[0033] like Figure 2 and Figure 4 The substrate 2 has a protective cover 24 for housing the detection circuit module 22 on the side near the battery pack 1. A sealing gasket 23 is fitted over the protective cover 24. The protective cover 24 is detachably mounted on the substrate 2, facilitating the operator to install and remove the protective cover 24 for maintenance of the detection circuit module 22. The protective cover 24 can be of any shape. In this embodiment, the protective cover 24 is an open cuboid shape, with the opening facing the substrate 2. Through holes 25 are provided on each surface of the protective cover 24. The battery pack 1 communicates with the internal space of the protective cover 24 through the through holes 25, so that the detection circuit module 22 can monitor the internal condition of the battery pack 1.

[0034] Multiple ear plates 3 are provided on the side of the substrate 2 facing the protective cover 24. The ear plates 3 are arranged along the outline of the opening of the protective cover 24, which can achieve the positioning effect of the protective cover 24. The protective cover 24 is connected to the ear plates 3 by threaded parts, such as screws, bolts, nuts, etc. In this embodiment, a fastening screw 31 is provided through the protective cover 24 at each position corresponding to the ear plate 3. The fastening screw 31 is threaded onto the corresponding ear plate 3, so that the protective cover 24 can be detachably fixed on the substrate 2.

[0035] The implementation principle of this application embodiment is as follows: the substrate 2 is detachably disposed outside the battery pack 1, and the detection circuit module 22 is inserted into the battery pack 1 to achieve the effect of in-pack detection. With this installation method, when the operator replaces or repairs the detector, there is no need to open the battery pack 1, which reduces the complicated process of protection detection of the battery pack 1 and helps to improve the efficiency of the operator in replacing or repairing the detector. Example 2

[0036] like Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that the two sets of opposite sidewalls of the protective cover 24 near the opening are respectively referred to as the first opposite sidewall and the second opposite sidewall. A plurality of L-shaped hook plates 4 are fixedly connected to the side of the base plate 2 facing the protective cover 24. The hook plates 4 are located near one of the sidewalls of the first opposite sidewall, and this sidewall has a slot 41 for inserting the hook plates 4. An elastic plate 42 is also fixedly connected to the base plate 2. The elastic plate 42 is located near the other sidewall of the first opposite sidewall, and a locking block 43 is fixedly connected to the side of the elastic plate 42 away from the hook plates 4. The locking block 43 has a slope 45 on the side away from the base plate 2, and a slot 44 for inserting the locking block 43 is provided on the side of the protective cover 24 near the elastic plate 42.

[0037] The implementation principle of this application embodiment is as follows: When installing the anti-slip cover, the operator first aligns the slot 41 on the protective cover 24 with the hook plate 4, and then moves the protective cover 24 so that the hook plate 4 is inserted into the slot 41. The operator then flips the anti-slip cover toward the base plate 2. During this process, the base plate 2 pushes the inclined surface 45, causing the locking block 43 to flip away from the corresponding side wall. When the anti-slip cover is flipped until the locking block 43 is aligned with the slot 44, under the elastic force of the elastic plate 42, the locking block 43 is inserted into the slot 44, thereby achieving the effect of detachably fixing the protective cover 24 on the base plate 2.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
