Description

Technical Field

[0001] This utility model belongs to the field of battery testing technology and relates to a detection device for energy storage power stations, specifically a suction-type detection device. Background Technology

[0002] With the large-scale deployment of energy storage power stations and containers, the demand for fire safety protection of lithium battery systems is becoming increasingly stringent, placing higher demands on the accuracy and response speed of early fire detection. Absorbing detection devices, with their active sampling and multi-parameter monitoring characteristics, have become an important early warning tool in energy storage scenarios. However, existing detection devices suffer from structural design flaws due to cost and space constraints: insufficient cavity sealing exacerbates external environmental interference, forcing sensors to possess ultra-high sensitivity to maintain detection reliability, significantly increasing hardware costs; simultaneously, the high integration of internal components and lack of maintenance access make troubleshooting difficult, requiring complete disassembly or even damage to the sealing structure during maintenance, greatly increasing maintenance costs and downtime. Furthermore, traditional cavity mold designs are complex and have low molding efficiency, making it difficult to balance lightweight design with structural strength requirements. How to construct a highly sealed, easily maintainable, and low-cost detection cavity structure within a limited space has become a key issue restricting the development of energy storage safety technology.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-2 As shown, this utility model provides an air-inhalation detection device, including: a first cavity 10, a second cavity 80 and a control board 90, wherein the first cavity 10 and the control board 90 are both disposed in the second cavity 80.

[0023] like Figure 3 As shown, the first cavity 10 includes: a first box body 1, a first cover body 2, a PCB board 3, an air intake fan 4, an air inlet pipe 5, and an air outlet pipe 6. The first box body 1 and the first cover body 2 are both integrally injection molded from nylon material. The first cover body 2 is sealed and connected to the first box body 1. The air inlet pipe 5 and the air outlet pipe 6 are both installed on the outer wall of the first box body 1 and connect to the interior of the first box body 1. The air intake fan 4 is installed on the inner wall of the first box body 1 on the side near the air inlet pipe 5. The PCB board 3 is provided with a sensor module. The PCB board 3 is set inside the first box body 1 and is sealed and connected to the lower end face of the first cover body 2. Thus, an independent air chamber is formed by the sealed connection between the first box 1 and the first cover 2. With the forced convection of the suction fan 4, the gas sample flows quickly through the detection area of ​​the sensor module, shortening the detection response time. Furthermore, through the integrated cavity design, the sensor module, airflow channel and sealing components are modularly integrated to achieve a compact layout of functional units, which is particularly suitable for installation in the narrow space of energy storage containers. Both the first box 1 and the first cover 2 are injection molded. By protruding the installation points of the air inlet pipe 5 and the air outlet pipe 6, the number of sliding covers of the injection mold is reduced, thus reducing costs.

[0024] The second cavity 80 includes a second cover 81 and a second housing 82. An operation panel 83 is mounted on the second cover 81 and is communicatively connected to a control board 90. The control board 90 is fixedly mounted on the upper surface of the first cover 2 and is communicatively connected to the PCB board 3 and the intake fan 4. By externally mounting the control board 90 on the upper surface of the first cover 2, firmware upgrades of the control board 90 do not require opening the first cavity 10, which serves as the detection chamber, thus improving upgrade efficiency.

[0025] like Figure 4 As shown, a first sealing groove 21 is provided on the lower end face of the first cover 2. The first sealing groove 21 is adapted to mate with the upper end face of the first box 1. An O-ring sealing strip is provided in the first sealing groove 21. The cooperation between the first sealing groove 21 and the O-ring sealing strip forms a three-dimensional sealing interface, maintaining stable compression and rebound characteristics, significantly improving the sealing level of the first cavity 10, reducing dependence on sensor sensitivity, and greatly reducing the sensor false alarm rate. Multiple first thermofused nuts 11 are provided on the periphery of the upper end face of the first box 1. Multiple first mounting holes 22 are provided on the first cover 2, corresponding to the multiple first thermofused nuts 11. Multiple first fastening screws 71 pass through the multiple first mounting holes 22 and are connected to the multiple first thermofused nuts 11 to fix the first cover 2 on the first box 1. Through the cooperation of the thermofused nut pre-embedding process and the screw fastening, the first cover 2 can be disassembled and assembled without special tools, which greatly reduces the assembly time compared with the traditional bolt connection.

[0026] A second sealing groove 23 is provided on the lower end face of the first cover 2. The second sealing groove 23 is adapted to connect with the PCB board 3. An O-ring sealing strip is provided in the second sealing groove 23. The second sealing groove 23, together with the silicone coating layer on the edge of the PCB board, forms a secondary protective barrier for the sensor module. The double sealing design significantly improves the sensor's anti-interference ability and further reduces the dependence on sensor sensitivity. A plurality of second thermoplastic nuts 24 are provided on the lower end face of the first cover 2. A plurality of second mounting holes 31 corresponding to the plurality of second thermoplastic nuts 24 are provided on the PCB board 3. A plurality of second fastening screws 72 pass through the plurality of second mounting holes 31 and are connected to the plurality of second thermoplastic nuts 24 to fix the PCB board 3 on the first cover 2. By suspending the PCB board 3 on the lower end face of the first cover 2, the vibration transmission of the first box 1 can be effectively isolated.

[0027] like Figure 5As shown, the inlet pipe 5 and the outlet pipe 6 have identical structures. The inlet pipe 5 includes a first pipe body 51, a second pipe body 52, and a dust filter 53. The first pipe body 51 is integrally formed on the outer wall of the first housing 1. The second pipe body 52 uses a pagoda-shaped adapter, compatible with various pipe diameters, improving the adaptability of the detection device. The second pipe body 52 is connected to the first pipe body 51. The dust filter 53 is positioned between the first pipe body 51 and the second pipe body 52. ​​The split pipe design facilitates the replacement of the dust filter 53. Furthermore, by externalizing the inlet pipe 5 and the outlet pipe 6, the dust filter 53, being a consumable item, can be removed without opening the first cavity 10 during replacement, facilitating maintenance. The first tube 51 is provided with a plurality of third thermosetting nuts 54, and the second tube 52 is provided with a plurality of third mounting holes 55 corresponding to the plurality of third thermosetting nuts 54. A plurality of third fastening screws 73 pass through the plurality of third mounting holes 55 and are connected to the plurality of third thermosetting nuts 54 to fix the second tube 52 to the first tube 51. The quick-release structure between the first tube 51 and the second tube 52 further facilitates the replacement of the dustproof net 53.
