DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here.

[0038] like Figure 1-Figure 11As shown, the present application provides an explosion-proof detector 100, which is used to detect the gas concentration in an explosive environment. The explosive environment is a general term, such as a chemical plant, metallurgical industry, or oil and gas industry, or energy storage power station in an industrial production environment. The specific explosive environment is not limited, because the purpose of the explosion-proof detector 100 in this embodiment is mainly to detect whether the concentration of combustible gas in the environment meets the standard of the application scenario. For example: in an energy storage power station, in order to accurately monitor and determine whether there is a fire hazard in a container, it is necessary to install an explosion-proof detector 100 of combustible gases such as CO, H2, VOC (Volatile Organic Compounds) generated when the lithium battery in the container runs away thermally, and then comprehensively summarize the concentration information of various combustible gases, and use the fire control machine to determine whether there is a fire in the container, and then report it to the fire protection system for fire alarm, fire extinguishing and other disposal.

[0039] Among them, the explosion-proof detector 100 specifically includes a shell 11, a detection component 12 and an integrated component 13. The detection component 12 and the integrated component 13 are both arranged inside the shell 11. The detection component 12 is arranged close to the entrance end of the shell 11, so as to quickly contact the air sample entering the shell 11, and the detection component 12 is also provided with a sensor 121 capable of detecting at least two combustible gas concentrations, so as to detect the concentrations of at least two of the combustible gases entering the shell 11; at the same time, the integrated component 13 is electrically connected to the detection component 12, that is, a signal connection, so as to collect the combustible gas concentration information detected by the detection component 12 and transmit it to the controller, and the controller makes further judgments based on the received combustible gas concentration information. In this embodiment, the combustible gas mentioned above refers to CO, H2, and VOC. In other embodiments, it can also include but not be limited to the above three combustible gases, which can be adjusted and changed according to the different usage scenarios of the explosion-proof detector 100, which will not be repeated here.

[0040] Therefore, in this embodiment, by providing a sensor 121 capable of detecting at least two kinds of combustible gases on a single detection member 12, the simultaneous detection of multiple combustible gas concentrations is achieved, thereby improving the detection efficiency and coverage. In addition, by combining multiple sensors 121 for detecting different types of combustible gases on one detection member 12, the number of installation points required in the environment where the explosion-proof detector 100 is located is reduced, which not only reduces the complexity and time cost of installing the explosion-proof detector 100, simplifies the installation process, but also saves the installation space of the environment where the explosion-proof detector 100 is located, and is particularly suitable for explosive environments with limited space. At the same time, by integrating at least two sensors 121 for detecting the concentration of combustible gases on one detection member 12, the sensors 121 on the detection member 12 are more compact. Therefore, by means of high-density integration, the limitation of the narrow area of ​​the detection member 12 is also overcome, and there is no need to combine the sensor components for detecting the concentrations of various types of combustible gases, which to a certain extent also solves the problem of limited installation space and limited use space of the explosion-proof detector 100. Furthermore, the integrated component 13 can collect gas concentration information from the detection component 12 and transmit it to the controller through an electrical connection, thereby realizing centralized processing of combustible gas concentration information, facilitating the controller's unified analysis of the combustible gas concentration information data, and improving the efficiency of the controller in determining the environmental state of the explosion-proof detector 100. In addition, through the accurate monitoring of the concentrations of various combustible gases in an explosive environment by the explosion-proof detector 100 in this embodiment, and timely response to potential dangers, the safety of the environment and the ability to prevent fire and explosion accidents are improved.

[0041] To sum up, the explosion-proof detector 100 in this embodiment can integrate the detection of multiple combustible gases, reduce installation points, save space, simplify the installation process and centralize information processing, thereby realizing efficient, simple and safe monitoring of combustible gas concentrations, and is suitable for safety monitoring needs in explosive environments.

[0042] Furthermore, the detection ends of the three sensors 121 in the present application are all oriented toward the side where the combustible gas enters, that is, the inlet end of the housing 11. Figure 3As shown, in the embodiment of the present specification, when the three sensors 121 of the present application are arranged, the relative position relationship of the three sensors 121 in space is also defined, that is: the three sensors 121 form a triangular layout, and each sensor 121 is respectively located at each vertex of the triangle, with a certain distance between each other. It can be understood that the three sensors 121 are not placed on the same straight line, but are dispersed to form a triangle. Preferably, in the present application, the distances between the three sensors 121 are set to be the same to form an equilateral triangle, so that after the various combustible gases diffuse into the interior of the shell 11, they can diffuse from the entrance end of the shell 11 to the surroundings, and due to the uniform layout of the sensors 121 and the diffusion behavior of the various combustible gases, the various combustible gas samples are evenly distributed in the area monitored by the sensor 121, and flow evenly to the detection end of each sensor 121, so as to facilitate the subsequent combustible gas concentration detection work. Therefore, with this design, no matter where the various types of combustible gas samples initially enter the monitoring area of ​​the sensor 121, they will eventually be evenly distributed within the monitoring range of the three sensors 121, ensuring that the combustible gas samples are evenly detected within the monitoring area, thereby improving the accuracy and reliability of the explosion-proof detector 100.

[0043] In addition, it should be noted that: since the explosion-proof detector 100 in this embodiment is located under normal atmospheric pressure conditions and in an environment with a temperature of -20°C to 85°C, when the sensors 121 for detecting the concentrations of various combustible gases are integrated into a detection component 12, no chemical reaction will occur between combustible gases such as H2 and CO and the sensors 121, because the high temperature, high pressure, and catalyst conditions for their chemical reaction are not reached in this environment. Therefore, no chemical reaction will occur between the sensors 121 and between the combustible gas and the sensors 121 for detecting the concentrations of other gases.

[0044] like Figure 2 , Figure 4 and Figure 7 As shown, the housing 11 includes a detachably connected probe 111 and a shell 112, and the detection element 12 is arranged inside the probe 111, that is, the probe 111 is arranged at the entrance end of the housing 11, so that the detection element 12 inside the probe 111 can detect the combustible gas entering the probe 111, and a sintered explosion-proof plate 14 is arranged at the entrance end of the probe 111, which is connected in a clamping manner. The sintered explosion-proof plate 14 is used to allow the combustible gas to flow and can block the flow of flames. Specifically, the sintered explosion-proof plate 14 is similar to a "filter", such as Figure 1-Figure 2As shown, the figure marks the entry direction X of the combustible gas into the interior of the probe. The combustible gas can flow through the sintered explosion-proof plate 14 between the interior of the probe 111 and the outside of the shell 11 along the entry direction X of the combustible gas into the interior of the probe. There is no need to provide power to inhale the combustible gas into the interior of the probe 111. The combustible gas can enter the interior of the probe 111 only through its own diffusion. In this way, by allowing the combustible gas to circulate naturally, it is ensured that the explosion-proof detector 100 can continuously and in real time monitor the concentration of the combustible gas in the explosive environment; and the sintered explosion-proof plate 14 also has the function of blocking the spread of flames. Even if an explosion occurs inside the explosion-proof detector 100, the sintered explosion-proof plate 14 can prevent the flame from spreading to the external explosive environment, thereby avoiding causing spontaneous combustion of the environment and further safety hazards. In this way, by blocking the spread of flames, the explosion risk caused by internal failures of the explosion-proof detector 100 during the detection process is reduced, and the safety monitoring level of the explosive environment is further improved.

[0045] Specifically, the integrated component 13 includes a computing component 131 and a main control 132. The computing component 131 is electrically connected to the detection component 12 and the main control 132, respectively, and the computing component 131 is arranged close to the detection component 12. In this embodiment, the detection component 12, the computing component 131 and the main control 132 are all circuit boards, and the computing component 131 and the main control 132 are both provided with chips. The computing component 131 and the main control 132 are electrically connected through a wiring harness 17 to achieve signal transmission therebetween. The detection component 12 is provided with a plurality of the sensors 121. Along the axial direction of the combustible gas entering the inside of the probe 111, which can also be understood as along the central axis direction of the probe 111, the detection component 12 and the computing component 131 are arranged coaxially, and the computing component 131 is arranged downstream of the detection component 12. The calculation component 131 and the detection component 12 are electrically connected by using pin headers and female headers, so that the calculation component 131 can use its internal chip to perform fast calculations of special algorithms based on the combustible gas concentration information of the detection component 12, and can quickly receive and process the combustible gas concentration information transmitted by the detection component 12, which not only reduces the attenuation and interference of the signal during transmission and maintains the integrity of the data, but also enables it to perform real-time or near-real-time data analysis and calculations, improves the speed and accuracy of data processing, and ensures that the combustible gas concentration information transmitted to the main control 132 is accurate and reliable. In addition, since the principle of each sensor 121 detecting the combustible gas concentration is to finally convert it into an electrical signal and transmit it to the chip of the calculation component 131, and the current is weak and rapid during the transmission process, it is necessary to control the distance between the sensor 121 and the chip so that the distance between the two is as small as possible. If the distance between the chip and the sensor 121 is too large, it will cause a delay in the transmission of the electrical signal, and even cause errors in the results of the combustible gas concentration detection. Therefore, in this embodiment, along the central axis direction of the probe 111, the straight-line distance between the detection element 12 and the operation element 131 is not greater than 5 cm to ensure the accuracy of signal transmission.

[0046] Furthermore, the main control 132 is electrically connected to the controller, and the main control 132 can collect and transmit the combustible gas concentration information calculated by the operation unit 131 to the controller, thereby realizing centralized control and management of information. And by designing the operation unit 131 and the main control 132 separately, modularization of functions is realized, which is convenient for the separate maintenance and replacement of each component. At the same time, in this embodiment, the straight-line distance between the operation unit 131 and the main control 132 is set in the range of 70mm-200mm, preferably 110mm, so that the accurate and complete transmission of the electrical signal is realized, and the problem of signal loss caused by the long distance between the operation unit 131 and the main control 132 is avoided.

[0047] In addition, the integrated component 13 also includes an adapter 133 and a display component 134. The main control 132, the adapter 133 and the display component 134 are all arranged inside the housing 112. The main control 132 and the display component 134 are respectively arranged on both sides of the adapter 133 and are both electrically connected to the adapter 133. Specifically, the adapter 133 is connected to the main control 132 through the adapter terminal 18, and the adapter 133 is further connected to the display component 134 through the terminal block 19. The main control 132 is used to collect the combustible gas concentration information of the detection component 12. The display component 134 is arranged near the outlet end of the housing 11 and can display the combustible gas concentration information collected by the main control 132 through the adapter 133. This arrangement enables the display component 134 to display the combustible gas concentration information collected by the main control 132 in real time, so that the operator can monitor and read the data.

[0048] Since the shell 11 of the explosion-proof detector 100 in the present application is made of metal, usually machined from aluminum alloy, in order to meet the explosion-proof performance requirements, the probe 111 is conductive. In order to ensure that the sensors 121 inside the probe 111 are not interfered with, that is, to prevent the probe 111 from conducting electricity to the sensors 121, the following two methods are used in this embodiment to avoid interference:

[0049] On the one hand, reference Figure 2 , respectively controlling the distance between the computing element 131 and the detection element 12 and the inner wall of the probe 111, so that the computing element 131 and the detection element 12 cannot contact the probe 111, so as to prevent someone from touching the probe 111 to form a loop and generate current, which will cause the entire explosion-proof detector 100 to falsely alarm. Therefore, in this embodiment, the distance between the computing element 131 and the detection element 12 and the inner wall of the probe 111 is controlled to be in the range of 0.3mm-0.8mm, preferably 0.5mm;

[0050] On the other hand, reference Figure 4 , the detection element 12 and the operation element 131 are connected by an isolation column 122, and the isolation column 122 and the probe 111 are also fixedly connected, and the isolation column 122 between the detection element 12 and the operation element 131 is made of metal, preferably copper, but the isolation column 122 between the operation element 131 and the probe 111 is made of insulating material, preferably nylon material, to isolate the conductivity between the operation element 131 and the probe 111;

[0051] In addition, reference Figure 2 The glue filling processing area M of the present application also performs glue filling processing between the side of the computing unit 131 facing the main control unit 132 and the inner wall surface of the probe 111, that is, Figure 2The black bubble area in the middle glue-filled processing area M, so that the glue-filled processing area can be covered on the outer wall surface of the isolation column 122, which not only completely fixes the operation element 131, but also supports the detection element 12 through the operation element 131.

[0052] In other embodiments, other mature technical means may be used to solve the insulation problem between the probe 111 and the sensor 121 to avoid electrical conduction and other safety hazards, and the specific embodiments are not limited thereto.

[0053] like Figure 2 , Figure 4 and Figure 7 As shown, the housing 11 also includes a fixed cover 113 detachably connected to the shell 112, and the display element 134 is arranged on the side of the adapter 133 facing the outlet end of the shell 112, and the fixed cover 113 is arranged on the outlet end of the shell 112 to cover the display element 134 and protect the display element 134 from external damage.

[0054] like Figure 2 and Figure 4 As shown, the surface where the main control 132 is located is parallel to the surface where the adapter 133 is located, and a limit column 15 is provided between the main control 132 and the adapter 133. The setting direction of the limit column 15 is perpendicular to the plane where the main control 132 and the adapter 133 are located. The limit column 15 passes through the main control 132 and the adapter 133 and is fixedly connected to the two respectively, thereby improving the stable support between the main control 132 and the adapter 133, ensuring the relative position between the main control 132 and the adapter 133 is stable, and preventing them from shifting due to vibration or impact. In addition, the design of the limit column 15 helps to reduce alignment errors during the assembly process, improve assembly accuracy and production efficiency.

[0055] like Figure 4 and Figure 8 As shown, the adapter 133 is provided with an avoidance groove 1331, and a communication interface 16 is provided on a side surface of the main control 132 facing the adapter 133. The communication interface 16 is located in the avoidance groove 1331 for electrical connection with the controller. The design of the avoidance groove 1331 avoids direct contact between the communication interface 16 provided on the main control 132 and the adapter 133, reduces the possibility of mechanical interference and wear, and prolongs the service life.

[0056] The present application also provides a battery compartment, which is used to accommodate batteries, wherein the battery compartment includes a battery compartment body, a controller and the explosion-proof detector 100 mentioned above, and the explosion-proof detector 100 is arranged inside the battery compartment body to detect the concentration of combustible gas inside the battery compartment body in real time, timely discover potential fire hazards, and improve the safety of the battery compartment.

[0057] The controller is electrically connected to the explosion-proof detector 100 , and the controller can receive the combustible gas concentration information sent by the explosion-proof detector 100 and judge the state of the battery, thereby realizing intelligent monitoring and control of the battery operation state.

[0058] Therefore, through real-time monitoring and intelligent control of the combustible gas concentration inside the battery compartment and the design of the integrated explosion-proof detector 100, not only the monitoring and management of the battery compartment are made more automated, the need for manual intervention is reduced and management efficiency is improved, but also timely measures can be taken to prevent the combustible gas concentration inside the battery compartment from exceeding the safety threshold, thereby effectively preventing the occurrence of fire.

[0059] Preferably, a spraying device is also provided inside the battery compartment body, and the spraying device is electrically connected to the controller. The spraying device can respond quickly based on the controller's instructions to determine the battery status, and quickly spray a fire extinguishing agent (usually perfluorohexanone) into the battery compartment body to effectively control and extinguish the fire. The spraying device is automatically activated by the controller's instructions, realizing automatic fire extinguishing of fires inside the battery compartment, reducing the need for human operation and potential dangers.

[0060] The explosion-proof detector 100 is provided with a channel for the circulation of combustible gas at its inlet end. The setting direction of the channel is the same as the rising direction of the combustible gas inside the battery compartment body. The design of the channel allows the combustible gas with a lower density to flow naturally along the rising airflow inside the battery compartment to the interior of the explosion-proof detector 100 without the need for additional power drive, thereby achieving the natural circulation of the combustible gas; and the naturally circulating combustible gas can quickly enter the interior of the explosion-proof detector 100, thereby improving its detection efficiency, allowing the explosion-proof detector 100 to respond to environmental changes more quickly, and to a certain extent can also reduce the energy consumption and possible interference during the flow of combustible gas, thereby improving the overall safety of the explosion-proof detector 100.

[0061] The above description has fully disclosed the specific implementation methods of the present application. It should be pointed out that any changes made by technicians familiar with the field to the specific implementation methods of the present application do not deviate from the scope of the claims of the present application.
