Description

Technical Field

[0001] This utility model relates to the field of sensor equipment, and in particular to a sensor mounting assembly. Background Technology

[0002] With the increasingly widespread application of energy storage systems, fire safety is of paramount importance. Current energy storage fire suppression systems face numerous challenges in combustible gas detection. Existing systems rely on temperature and smoke sensors, which miss the early gas escape phase when thermal runaway occurs, resulting in delayed warnings. Ordinary combustible gas detectors are susceptible to false alarms triggered by cross-sensitive gases. Furthermore, within the compact space of the energy storage battery compartment, existing detectors require drilling and wiring, compromising IP protection ratings, and necessitate frequent disassembly, calibration, or replacement, making maintenance inconvenient.

[0027] 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.

[0028] Reference Figures 1-6 The present invention provides an embodiment of a sensor mounting assembly, comprising: a bracket 1; a sensor 2 is disposed inside the bracket 1, and the bracket 1 is used to mount and protect the sensor 2; the signal line of the sensor 2 passes through the bracket 1 and is connected to the processor in the module box 3.

[0029] In this embodiment, sensor 2 is installed and fixed by bracket 1, and placed inside the battery compartment. Detection is performed through the vertical detection hole 13, which avoids interference from dust and condensation. Sensor 2 is connected to the processor in module box 3 via a signal line for signal processing and judgment. Sensor 2 is a MOS semiconductor sensor that monitors hydrogen and electrolyte vapor in real time. The monitoring signal is transmitted to the processor in module box 3 via an RJ45 shielded cable. The processor performs dynamic threshold analysis on the gas concentration change rate based on the monitoring signal, with a sampling frequency ≥1Hz. After confirming a valid alarm, an output is triggered. When an alarm occurs, the alarm relay in module box 3 connects to the fan or fire extinguishing device, and the status is displayed by red (alarm), yellow (fault), and green (normal / flashing preheating) indicator lights. Real-time concentration, equipment status, and other data can be uploaded via RS485 (Modbus RTU) or CAN (125Kbps standard frame) protocol. Sensor 2 connection is checked every 5 seconds. When the connection is broken, the yellow light stays on and the fault relay activates. The alarm needs to be manually reset, and the fault is automatically resolved.

[0030] The bracket 1 includes a detection part 11 and bending parts 12 located around the detection part 11. The bending parts 12 are perpendicular to the detection part 11. The detection part 11 and the bending parts 12 are integrally connected, and adjacent bending parts 12 are connected by welding. The detection part 11 and the bending parts 12 form a receiving cavity for mounting the sensor 2.

[0031] In this embodiment, the detection unit 11 is a planar plate structure with bent portions 12 extending vertically from all four sides, forming a semi-enclosed receiving cavity; adjacent bent portions 12 are connected by welding to ensure the rigidity of the overall structure. The spatial dimensions of the receiving cavity match the sensor 2, fixing the sensor to prevent shaking, and the bent portions can also block external impacts.

[0032] The detection section 11 has a detection hole 13.

[0033] In this embodiment, the detection hole 13 is opened in the central area of ​​the detection section 11, and the aperture is matched with the size of the detection head of the sensor 2 to ensure that the sensor can identify and monitor the detection object. Specifically, the sensor 2 vertically detects hydrogen (H2) and electrolyte vapor (DEC / DMC) in the battery compartment through the detection hole 13.

[0034] Mounting portions 14 are provided on the bending portions 12 on either side of the bending portions 12, and the mounting portions 14 are perpendicular to the bending portions 12; mounting holes 15 are provided on the mounting portions 14 for mounting the bracket 1.

[0035] In this embodiment, mounting portions 14 extend vertically from the bends 12 on opposite sides, forming symmetrical mounting supports to ensure that the bracket 1 is balanced under force after fixing, avoiding tilting caused by single-point fixing. The mounting holes 15 are oblong or round holes, which are fixed inside the battery compartment by bolts.

[0036] The module box 3 includes a box body 31 and a back plate 32. The box body 31 has several through holes 33. The through holes 33 are located on the side end face of the box body 31. The box body 31 and the back plate 32 are connected by bolts.

[0037] In this embodiment, the box body 31 and the back plate 32 are connected by bolts. The bolts are located at the four corners of the box body 31. The dimensions of the module box 3 are 280×280×130mm. Three through holes 33 are provided for connecting power lines, signal lines and grounding lines, which is compatible with the existing energy storage electrical compartment layout.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
