[0002] The noise pollution monitoring device disclosed in CN211740388U includes a microphone, a housing, and a circuit board. The circuit board includes a processor, a sensing module, a digital-to-analog converter module, a logic operation module, a wireless module, a communication module, a display module, a memory, and a power management module. Before transmitting the detected data to the processor, the analog signal collected by the sensing module is converted into a digital signal by the digital-to-analog converter module. After the digital signal is transmitted to the processor, the logic operation module compares the collected data with a standard decibel value. Then, the data is stored in the memory for later retrieval. The processed data is displayed by the display module, and the processed data is transmitted to the communication module.

[0003] Through its wireless module, it can transmit the collected data to a wirelessly-enabled terminal for storage and future processing.

[0004] The technical solution in the prior art document has the effect of remote data transmission, but the defects are also more obvious. For example, in the working environment of liquefied petroleum gas or natural gas, the noise monitoring sensor may ignite liquefied petroleum gas or natural gas due to electric sparks generated by buttons or short circuits in the battery, which poses a certain safety hazard and lacks a structure to protect it from explosion. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an explosion-proof noise monitoring sensor, which solves the problem that in working environments involving liquefied petroleum gas or natural gas, noise monitoring sensors may ignite liquefied petroleum gas or natural gas due to electrical sparks generated by buttons or short circuits in batteries, posing a certain safety hazard, and lacking a structure to protect them from explosion.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof noise monitoring and sensing device, comprising a noise monitoring and sensing body, wherein a flame-retardant component is provided on the surface of the noise monitoring and sensing body, and a sealing component is fixedly connected to the top surface of the flame-retardant component.

[0007] The flame-retardant component includes a flame-retardant medium layer fixedly connected to the surface of the noise monitoring sensor body, and a protective shell is fixedly connected to the surface of the flame-retardant medium layer.

[0008] In one specific embodiment, the surface of the protective shell is provided with an antistatic coating, and the top surface of the protective shell has an operating port.

[0009] In one specific embodiment, both the flame-retardant medium layer and the protective shell have screw holes for installation on their surfaces, and the screw holes are internally threaded with bolts for installation.

[0010] In one specific embodiment, the top surface of the noise monitoring sensor body is provided with a mounting hole corresponding to the screw hole, and the mounting hole is threaded to the bottom end of the bolt.

[0011] In one specific embodiment, the sealing assembly includes a rubber operating plate fixedly connected to the surface of the operating port, and a plurality of rubber button films are provided on the top surface of the rubber operating plate.

[0012] In one specific embodiment, the top surface of the rubber operating plate is provided with an observation port, and an observation window is fixedly connected to the top surface of the observation port.

[0013] Compared with the prior art, this utility model provides an explosion-proof noise monitoring sensor device, which has the following beneficial effects:

[0014] The technical solution disclosed in this utility model effectively isolates the electrical sparks or short-circuit heat that may be generated inside the equipment through the dual protection of flame-retardant components and sealing components, preventing the ignition of flammable and explosive gases such as liquefied petroleum gas and natural gas, and significantly reducing the risk of explosion.

[0015] The flame-retardant and sealing components of this invention significantly improve the safety and functionality of the equipment in flammable and explosive environments such as those involving liquefied petroleum gas or natural gas. The flame-retardant component comprises a flame-retardant medium layer fixed to the surface of the noise monitoring sensor and a protective shell covering it, forming a dual flame-retardant protection structure. This structure effectively blocks the spread of flames caused by electrical sparks or short circuits and resists the intrusion of external ignition sources, effectively controlling fire hazards. Simultaneously, the anti-static coating on the protective shell eliminates static electricity accumulation, preventing electrostatic discharge from igniting hazardous gases. The sealing component consists of a rubber operating panel and a rubber button membrane covering its top. Its elastic sealing design isolates external dust, moisture, and flammable gases from entering the equipment, while also preventing the leakage of electrical sparks generated during button operation, achieving physical isolation and explosion-proof protection. Furthermore, the equipment provides visual data monitoring through an observation window and uses bolts to penetrate the flame-retardant medium layer, the protective shell, and the screw holes of the noise monitoring sensor for secure connection, balancing ease of installation and structural stability. Ultimately, this achieves safe, reliable, and efficient noise monitoring operations in flammable and explosive environments. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 As an embodiment of the present invention, an explosion-proof noise monitoring sensor device includes a noise monitoring sensor body 1, a flame-retardant component 2 is provided on the surface of the noise monitoring sensor body 1, and a sealing component 3 is fixedly connected to the top surface of the flame-retardant component 2.

[0024] The specific problem addressed in this embodiment is the lack of structural explosion-proof protection for noise monitoring sensors operating in environments containing liquefied petroleum gas (LPG) or natural gas. This is because such sensors may ignite LPG or natural gas due to electrical sparks from button presses or battery short circuits. The invention utilizes a dual protection system of flame-retardant component 2 and sealing component 3 to effectively isolate potential electrical sparks or short-circuit heat generated inside the device, preventing the ignition of flammable and explosive gases such as LPG and natural gas, and significantly reducing the risk of explosion.

[0025] The flame-retardant component 2 includes a flame-retardant medium layer 21 fixedly connected to the surface of the noise monitoring sensor body 1, and a protective shell 22 is fixedly connected to the surface of the flame-retardant medium layer 21; the sealing component 3 includes a rubber operating plate 31 fixedly connected to the surface of the operating port, and a plurality of rubber button films 32 are provided on the top surface of the rubber operating plate 31. In this specific embodiment, the surface of the protective shell 22 is provided with an antistatic coating 4, and an operating port is opened on the top surface of the protective shell 22. In flammable and explosive environments such as those involving liquefied petroleum gas or natural gas, the safety and functionality of the equipment are significantly improved. The flame-retardant component 2 includes a flame-retardant medium layer 21 fixed to the surface of the noise monitoring sensor body 1 and a protective shell 22 covering the outside. The two form a dual flame-retardant protection structure, which can block the spread of flames caused by electric sparks or short circuits inside and resist the intrusion of external fire sources, effectively controlling fire hazards. At the same time, the antistatic coating 4 coated on the surface of the protective shell 22 can eliminate static electricity accumulation and prevent electrostatic discharge from igniting dangerous gases. The sealing component 3 consists of a rubber operating plate 31 and a rubber button film 32 covering its top. Through the elastic sealing design, it isolates external dust, moisture and flammable gases from entering the equipment, while preventing the leakage of electric sparks generated when operating the buttons, thus achieving physical isolation and explosion protection. In addition, the equipment provides a visual data monitoring function through the observation window 6, and uses bolts 5 to pass through the screw holes of the flame-retardant medium layer 21, the protective shell 22 and the noise monitoring sensor body 1 for fastening connection, taking into account both installation convenience and structural stability, and finally achieving safe, reliable and efficient noise monitoring operations in flammable and explosive environments.

[0026] In this specific embodiment, the surface of the protective shell 22 is provided with an antistatic coating 4, and the top surface of the protective shell 22 is provided with an operation port; the antistatic coating 4 on the surface of the protective shell 22 can prevent static electricity accumulation, further eliminate the safety hazard caused by sparks due to electrostatic discharge, and meet the needs of high-risk environments.

[0027] The top surface of the rubber control panel 31 is provided with several rubber button films 32, and the top surface of the rubber control panel 31 is provided with an observation port, and the top surface of the observation port is fixedly connected to an observation window 6; the rubber button films 32 in the sealing assembly 3 achieve physical sealing while allowing users to operate the equipment through flexible buttons, taking into account both functionality and safety; the observation window 6 is designed to ensure that the display module is visible without compromising the overall sealing performance.

[0028] Both the flame-retardant medium layer 21 and the protective shell 22 have screw holes for installation on their surfaces, and the screw holes are threaded with bolts 5 for installation. The installation method of fixing with bolts 5 not only ensures a tight connection between the flame-retardant component 2 and the equipment body, but also facilitates disassembly, maintenance or replacement of parts, thereby extending the service life of the equipment.

[0029] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
