Technical Field
[0001] The present application relates to the field of detectors, and in particular to a composite detector. Background Art
[0002] Composite detectors are devices that integrate multiple detection functions and are widely used in electrical equipment, power distribution systems, and energy storage devices. They monitor key parameters such as temperature changes, combustible gas concentrations, and smoke density. For example, in the battery compartment of an energy storage container, which consists of multiple battery packs, composite detectors can monitor real-time changes in combustible gas concentration, temperature, and smoke density within the battery packs. This allows for timely determination of fire hazards or actual fires, providing crucial information for rapid firefighting measures.
[0003] Traditional detectors are often installed inside battery packs. However, due to their limited lifespan, operators must regularly replace and maintain them. This process requires opening the battery pack, which is not only cumbersome but also requires reassessing the battery pack's protection level after replacement or maintenance. The entire process is time-consuming and labor-intensive, significantly impacting operator efficiency. Utility Model Content

[0007] The detector body includes a shell and a cover plate. The detection element is arranged in the shell. An opening is provided on the shell. The cover plate is detachably arranged on the opening of the shell. The through hole is provided on the cover plate.

[0009] Optionally, when the cover plate is installed on the target device, the portion of the cover plate where the through hole is provided can extend into the target device.
[0010] By adopting the above technical solution, the design in which the cover part extends into the interior of the target device can more directly contact and detect the internal conditions of the target device, thereby improving the accuracy and timeliness of the detection.
[0011] Optionally, the cover plate includes a connecting portion for connecting to the shell, the connecting portion is fixedly connected to an extension tube, and the through holes are provided on the extension tube and distributed on each surface of the extension tube;
[0012] When the cover plate is installed in the mounted state of the target device, the extension tube can extend into the target device.
[0013] By adopting the above technical solution, the opening position of the cover plate is fixed to the connecting portion, the connecting portion is provided with an extension tube, and the through holes are distributed on the extension tube, which can more effectively guide the gas or substance inside the target device to flow to the detection element, thereby improving the accuracy and sensitivity of the detection;
[0014] The shell and the connecting part are detachably connected, and the connecting part is installed on the outer shell of the battery pack. When the operator inspects the shell, he removes the shell from the connecting part, and then inspects the detection elements or circuit connections inside the detector body. In the process of installing and disassembling the detector body, the operator directly installs and disassembles the shell with the connecting part, and the connecting part does not need to be installed and disassembled with the outer shell of the battery pack, which is beneficial to reduce the wear of the battery pack outer shell caused by multiple installation and disassembly of the detector body.
[0015] Optionally, a pressing plate is provided on the cover plate, and the cover plate cooperates with the pressing plate to clamp the side wall of the target device, and the cover plate and the pressing plate are detachably connected.
[0016] By adopting the above technical solution, a pressure plate is provided on the cover plate, and the pressure plate and the cover plate cooperate to clamp the side wall of the target device, thereby achieving a stable connection between the detector and the target device, which is conducive to enhancing the stability and reliability of the detector.
[0017] Optionally, a first threaded member is provided on the pressing plate, and the first threaded member passes through a side wall of the target device and connects the pressing plate and the cover plate.
[0018] By adopting the above technical solution, a first threaded member is provided on the pressure plate, and penetrates the side wall of the target device to connect the pressure plate and the cover plate, thereby achieving a firm fixation of the detector and the target device, further improving the installation stability and detection accuracy of the detector.

[0023] Optionally, a waterproof electrical connector is provided on the housing for supplying power to the detection element and transmitting signals.
[0024] By adopting the above technical solution and setting up waterproof electrical connectors on the shell, not only the normal power supply and signal transmission of the detection elements are guaranteed, but also the waterproof performance of the detector is improved, enabling it to work stably in humid or underwater environments, and broadening the application range of the detector.
[0025] Optionally, an indicator light is provided on the housing, the indicator light is electrically connected to the detection element, and the indicator light can display different lighting effects according to the operating status of the detector.
[0026] By adopting the above technical solution, the traditional detector is set inside the target device, and the operator cannot directly observe and judge the normal, faulty, alarm and other operating status of the detector.

[0029] 2. The housing and the connecting part are detachably connected. The connecting part is installed on the outer shell of the battery pack. When inspecting the housing, the operator removes the housing from the connecting part to inspect the detection elements or circuit connections inside the detector body. During the process of installing and removing the detector body, the operator directly installs and removes the housing from the connecting part, without having to install and remove the connecting part from the outer shell of the battery pack. This helps to reduce the wear and tear of the battery pack outer shell caused by repeated installation and removal of the detector body.
[0030] 3. The indicator light is set on the shell, and the housing is set outside the target device. The operator can intuitively see the status of the indicator light, which makes it easier for the operator to judge the operating status of each detector. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-6 This application is described in further detail. Example 1
[0039] The present application embodiment discloses a composite detector. Figure 1 and Figure 2 The composite detector includes a detector body 2 for installation outside a target device. The target device can be some electrical equipment or energy storage device. In the embodiment of the present application, the target device is a battery pack 1 within an energy storage container. The outer shell of the battery pack 1 is provided with a mounting hole 11, which communicates with the interior of the battery pack 1. The detector body 2 can be removably installed outside the battery pack 1. The detector body 2 is provided with a detection element (not shown in the figure) and has a through hole 3. When the detector body 2 is fixedly connected to the outside of the battery pack 1, the through hole 3 communicates with the mounting hole 11, so that the interior of the detector body 2 is connected to the interior of the battery pack 1.
[0040] The detection elements include a hydrogen concentration detection unit, a carbon monoxide concentration detection unit, a smoke concentration detection unit, and a temperature detection unit, etc., which are used to monitor data such as the hydrogen concentration, carbon monoxide concentration, smoke concentration, and temperature in the battery pack 1 so as to determine or predict whether the battery pack 1 has a fire risk.
[0041] like Figure 1 and Figure 3 The detector body 2 includes a shell 4 and a cover 5. The shell 4 has a cavity, and the detection element is installed in the cavity of the shell 4. The shell 4 also has an opening that communicates with the shell's own cavity. The opening of the shell 4 is detachably connected to the cover 5. The cover 5 includes a connecting portion 51 that is detachably fixedly connected to the opening of the shell 4. The connecting portion 51 is integrally formed with an extension tube 52. The detection element extends into the extension tube 52, and through holes 3 are provided on each surface of the extension tube 52. When the detector body 2 is fixedly connected to the battery pack 1, the extension tube 52 on the cover 5 extends from the mounting hole 11 into the battery pack 1, increasing the contact area between the detection element and the internal space of the battery pack 1.
[0042] like Figure 3 and Figure 4 The cover plate 5 is provided with a pressing plate 6. The connecting portion 51 of the cover plate 5 and the pressing plate 6 cooperate to clamp the shell wall of the battery pack 1. The pressing plate 6 is provided with a first threaded member 7. The first threaded member 7 passes through the shell wall of the battery pack 1 and connects the connecting portion 51 of the cover plate 5 and the pressing plate 6.
[0043] The first threaded member 7 can be a bolt-nut connection, a stud-nut connection, or a bolt-screw-hole threaded connection. In the embodiment of the present application, the first threaded member 7 comprises a first bolt that extends through the pressure plate 6. The first bolt penetrates both the pressure plate 6 and the side wall of the battery pack 1 and extends toward the connecting portion 51. The connecting portion 51 is provided with a first screw hole, and the end of the first bolt extending toward the connecting portion 51 is threadedly connected to the first screw hole, so that the pressure plate 6 and the pressure plate 6 clamp the side wall of the battery pack 1 shell, thereby fixing the position of the cover plate 5 on the battery pack 1 shell.
[0044] In order to improve the sealing performance of the connection between the cover plate 5 and the outer shell of the battery pack 1, a first sealing gasket 71 is provided on the side of the connection portion 51 of the cover plate 5 facing the outer shell of the battery pack 1, so that the cover plate 5 can be sealed and fixed on the battery pack 1. At this time, the outer shell of the battery pack 1 is connected to the outside world through the through hole 3 on the extension tube 52; when the operator fixes the shell 4 to the connection portion 51 of the cover plate 5, the inner cavity of the battery pack 1 is connected to the inner cavity of the shell 4.
[0045] The housing 4 and the cover plate 5 are detachably connected, that is, the connecting portion 51 is detachably mounted on the housing 4. The housing 4 and the connecting portion 51 may be connected by a snap-fit connection, a threaded connection, or a tight-fitting plug-in fixation. In the embodiment of the present application, the housing 4 and the connecting portion 51 are connected by a second threaded member 8. The second threaded member 8 includes a second bolt that extends through the housing 4. The second bolt extends through one end of the housing 4 to the connecting portion 51 and is connected to the connecting portion 51. The connecting portion 51 is provided with a second screw hole for threadably engaging the second bolt. The second bolt is threadably connected to the second screw hole, thereby achieving detachable installation of the housing 4 and the connecting portion 51.
[0046] To improve the sealing between the housing 4 and the connecting portion 51, a second sealing gasket 81 is provided on the end of the housing 4 facing the connecting portion 51. When the housing 4 and the connecting portion 51 are fixed together via the second threaded member 8, the second sealing gasket 81 is clamped, thereby achieving a seal between the housing 4 and the connecting portion 51. This ensures that when the entire detector body 2 is fixed to the outer shell of the battery pack 1, the inner cavity of the battery pack 1 is directly connected to the inner cavity of the detector body 2, and the battery pack 1 and the detector body 2 are sealed together, ensuring the sealing of the battery pack 1.
[0047] In addition, a waterproof electrical connector 9 is added to the housing 4 of this embodiment. The waterproof electrical connector 9 can be used in a water environment and can ensure that the internal mechanical and electrical properties of the connector can be used normally under a certain water pressure.
[0048] The waterproof electrical connector 9 is used on the detector to power the detection elements and transmit signals. It can also effectively prevent moisture or other liquids from entering the interior of the detector body 2, thereby ensuring the normal operation and safety of the detector. The design of the waterproof electrical connector should meet relevant waterproof standards and requirements to ensure its good waterproof performance.
[0049] The principle of the embodiment of the present application is as follows: the detector body 2 is designed to be detachably arranged on the outside of the target device, and has built-in detection elements and through holes 3 to achieve internal and external connectivity, so that the composite detector is not only convenient for detecting the inside of the target device, but also easy to disassemble and repair, thereby improving detection efficiency and convenience of equipment maintenance.
[0050] Furthermore, the housing 4 is detachably connected to the connecting portion 51, which is mounted on the outer shell of the battery pack 1. When inspecting the housing 4, the operator simply removes the housing 4 from the connecting portion 51 to access the detection components or circuit connections within the detector body 2. During installation and removal of the detector body 2, the operator directly installs and removes the housing 4 from the connecting portion 51, without having to install and remove the connecting portion 51 from the outer shell of the battery pack 1. This helps reduce wear on the outer shell of the battery pack 1 caused by repeated installation and removal of the detector body 2. Example 2
[0051] like Figure 5 The rest of the embodiment of the present application is the same as that of the first embodiment, except that the pressing plate 6 is sleeved on the extension tube 52 and threadedly connected to the extension tube 52. The operator extends the extension tube 52 of the cover plate 5 through the mounting hole 11 into the battery pack 1, and then threadably connects the pressing plate 6 to the extension tube 52 from the inner side of the battery pack 1, so that the pressing plate 6 and the connecting portion 51 can clamp onto the shell wall of the battery pack 1, thereby fixing the position of the cover plate 5 on the shell of the battery pack 1. Example 3
[0052] like Figure 6 The rest of the embodiment of the present application is the same as that of embodiment 1, except that an indicator light 12 is provided on the housing 4. The indicator light 12 is electrically connected to the detection element and can display different lighting effects according to the different operating states of the detector. In the embodiment of the present application, there are three indicator lights 12, and the three indicator lights 12 correspond to the normal, fault, and alarm states of the detector, respectively, and the corresponding colors of the three indicator lights 12 are different.
[0053] Conventional detectors are located inside the target device, and operators cannot directly observe and determine the detector's operating status, such as normal, faulty, or alarming. Operators can only determine the status of each detector through signals transmitted to the host controller by conventional detectors. In the present application, the housing 4 is located outside the battery pack 1, and the indicator light 12 is located on the housing 4. This allows the operator to intuitively see the color displayed by the indicator light 12, making it easier to determine the operating status of each detector, thereby improving the operator's efficiency in inspecting and maintaining each battery pack 1.
[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
