Description

Technical Field

[0001] This utility model relates to a methane and oxygen detection alarm device, specifically a dustproof and waterproof methane and oxygen detection alarm device for coal mine safety detection. Background Technology

[0002] The dustproof and waterproof methane and oxygen detection alarm device for coal mine safety inspection is a safety monitoring device specially designed for the complex environment of underground coal mines. It integrates methane and oxygen concentration detection functions, and has dustproof and waterproof performance to adapt to the harsh conditions of dust and humidity underground.

[0003] Current methane and oxygen detectors consist of a housing, a methane-supported catalytic element, an oxygen sensor, and a circuit board. Methane and oxygen gases in the air are converted into corresponding electrical signals by the detector. These signals are amplified, filtered, and processed by a microcontroller, then displayed digitally as the concentrations of methane and oxygen in the air. When the methane concentration exceeds the limit (posing an explosion risk) or the oxygen concentration is too low (potentially causing suffocation), the alarm circuit immediately sounds an alarm signal to indicate that the concentration has exceeded the limit. This alerts on-site personnel to take timely evacuation and ventilation measures, effectively preventing gas explosions, oxygen deficiency, and other safety accidents, thus ensuring safe coal mine production.

[0004] The methane and oxygen detection alarm has a fixed methane inlet cover, with a dust screen installed below it. External methane and oxygen enter the detection element through the methane inlet cover and dust screen. However, the existing methane inlet cover of the methane detection alarm has a relatively complex assembly and disassembly structure. Assembly requires cumbersome operations to complete the fixing, and disassembly is also quite troublesome, resulting in low assembly and disassembly efficiency. This makes it inconvenient for users to regularly clean and maintain the inlet cover and internal detection channel. At the same time, due to the inconvenience of assembly and disassembly, impurities in the air can easily enter with the airflow and cause blockages, thereby affecting the continuity and accuracy of methane and oxygen concentration detection. This increases the risk of alarm delays or false alarms due to equipment blockage, reducing the reliability of safety monitoring in coal mines. Utility Model Content

[0005] The purpose of this invention is to provide a dustproof and waterproof methane and oxygen detection alarm device for coal mine safety monitoring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dustproof and waterproof methane and oxygen detection alarm device for coal mine safety detection includes a methane and oxygen detection alarm body and a control panel disposed on the methane and oxygen detection alarm body. The upper surface of the methane and oxygen detection alarm body has two cavities and a methane inlet cover disposed on the cavity for collecting methane and oxygen. A filter assembly for filtering air is installed at the bottom of the methane inlet cover. A rotating locking mechanism is rotatably installed on the methane inlet cover. A socket fastening mechanism is provided on the cavity of the methane and oxygen detection alarm body.

[0008] The socket fastening mechanism includes a sliding socket mechanism mounted on the cavity and an elastic locking mechanism for locking the rotating locking mechanism.

[0011] The dustproof and waterproof methane and oxygen detection alarm device for coal mine safety inspection described above: the sliding socket mechanism includes two connecting bases that are respectively fixedly connected to two cavities, and a limit socket is installed on the connecting base.

[0012] The dustproof and waterproof methane and oxygen detection alarm device for coal mine safety inspection described above: the top of the limiting socket is provided with a slot and a groove is provided at the bottom of the slot, and the slot and the groove are connected.

[0013] The dustproof and waterproof methane and oxygen detection alarm device for coal mine safety inspection described above: the rotating locking mechanism further includes two annular grooves opened below the rotating shaft, and the bottom of the rotating shaft is provided with an inclined groove.

[0014] The dustproof and waterproof methane and oxygen detection alarm device for coal mine safety inspection described above includes an elastic locking mechanism comprising two housings fixedly connected to both sides of the limiting socket and a first spring installed inside the housing. A spherical locking component is connected to the first spring, and the two spherical locking components respectively cooperate with two annular grooves. A second spring for elastically resetting the rotating shaft is installed on the groove. The inclined groove at the bottom of the rotating shaft is in a pressing fit with the two spherical locking components.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: the methane inlet cover adopts an innovative detachable structure, which greatly improves the ease of use and maintenance efficiency; during assembly, the internal locking block of the instrument is moved by the insertion action, and after being inserted to the bottom, the methane inlet cover can be quickly fixed, ensuring the stability of the detection process and the smooth flow of air; during disassembly, simply rotate the methane inlet cover at a certain angle, and the locking block will automatically retract, which can easily complete the disassembly, making it convenient for timely cleaning or replacement, effectively preventing blockage caused by impurities in the air, thereby ensuring the long-term stable operation and detection accuracy of the detection alarm.

[0016] This utility model also features strong ease of operation. Without the need for complex tools, workers can quickly complete the disassembly and assembly in the complex environment of underground coal mines, saving operation time and physical strength. The structural design of insertion and rotation retraction is stable and reliable, which can reduce the situation of air inlet cover loosening and falling off due to vibration, collision, etc., ensuring the stable operation of the device under harsh underground working conditions. Moreover, it can maintain good fit accuracy after multiple disassembly and assembly, extending the service life of the device. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-9 As an embodiment of this utility model, the dustproof and waterproof methane and oxygen detection alarm device for coal mine safety detection includes a methane and oxygen detection alarm body 1 and a control panel 2 disposed on the methane and oxygen detection alarm body 1. The upper surface of the methane and oxygen detection alarm body 1 has two cavities 3 and a methane inlet cover 4 disposed on the cavity 3 for collecting methane and oxygen. The bottom of the methane inlet cover 4 is equipped with a filter component for filtering air. A rotating locking mechanism is rotatably mounted on the methane inlet cover 4. A socket fastening mechanism is provided on the cavity 3 of the methane and oxygen detection alarm body 1.

[0029] The socket fastening mechanism includes a sliding socket mechanism installed on the cavity 3 and an elastic locking mechanism for locking the rotating locking mechanism.

[0030] In this embodiment, external methane and oxygen enter the internal detection element through the methane inlet cover 4 and the filter assembly. The methane inlet cover 4 and the methane and oxygen detection alarm body 1 in this structure adopt a quick disassembly and assembly design. During assembly, the methane inlet cover 4 is aligned with the cavity 3, and then pressed down into the sliding socket mechanism by insertion. At the same time, the elastic locking mechanism will be squeezed and contracted. After insertion to the bottom, the elastic locking mechanism quickly returns to its original position, thus achieving quick fixation of the methane inlet cover 4.

[0031] During disassembly, the rotating locking mechanism on the methane inlet cover 4 is rotated. When rotated at a certain angle, the elastic locking mechanism will be squeezed and contracted, making disassembly easy and convenient for timely cleaning or replacement. This effectively prevents blockage caused by impurities in the air, thereby ensuring the long-term stable operation and detection accuracy of the detector and alarm.

[0032] As a further embodiment of this utility model, the filter assembly includes multiple air inlets 5 opened on the methane air inlet cover 4 and a connecting plate 6 installed at the bottom of the methane air inlet cover 4, and multiple dustproof nets 7 are installed on the connecting plate 6.

[0033] In this embodiment, multiple air inlets 5 on the methane inlet cover 4 are used to allow methane and oxygen to enter, and a dustproof net 7 fixed below the methane inlet cover 4 filters dust in the air.

[0034] As a further embodiment of this utility model, the rotating locking mechanism includes a rotating shaft 8 rotatably mounted on the methane inlet cover 4 and a cross-shaped adjusting plate 9 mounted on the top of the rotating shaft 8, wherein the rotating shaft 8 passes through the methane inlet cover 4 and the connecting plate 6.

[0035] In this embodiment, the rotating shaft 8 is mounted on the methane inlet cover 4, and the rotating shaft 8 can be adjusted by the cross-shaped adjusting plate 9.

[0036] As a further embodiment of this utility model, the sliding socket mechanism includes two connecting bases 18 that are respectively fixedly connected to the two cavities 3, and a limit socket 12 is installed on the connecting bases 18.

[0037] In this embodiment, the connecting base 18 and the cavity 3 are fixedly connected by bolts before use, so that the limiting socket 12 is fixed on the cavity 3.

[0038] As a further embodiment of this utility model, the top of the limiting socket 12 is provided with a slot 13 and a groove is provided at the bottom of the slot 13, and the slot 13 is connected to the groove.

[0039] In this embodiment, the slot 13 on the limiting socket 12 is fitted with the outer wall of the rotating shaft 8, and the slot 13 is connected to the groove.

[0040] As a further embodiment of this utility model, the rotating engagement mechanism also includes two annular grooves 10 formed below the rotating shaft 8, and an inclined groove 11 is formed at the bottom of the rotating shaft 8.

[0041] In this embodiment, two annular grooves 10 are formed below the rotating shaft 8, and inclined grooves 11 are formed at the bottom of the rotating shaft 8.

[0042] As a further embodiment of this utility model, the elastic locking mechanism includes two housings 15 fixedly connected to both sides of the limiting socket 12 and a first spring 16 installed inside the housing 15. A spherical locking member 17 is connected to the first spring 16. The two spherical locking members 17 respectively cooperate with two annular grooves 10. A second spring 14 for elastically resetting the rotating shaft 8 is installed on the groove. The inclined groove 11 at the bottom of the rotating shaft 8 is in a pressing fit with the two spherical locking members 17.

[0043] In this embodiment, during assembly, the methane inlet cover 4 corresponds to the cavity 3, and is then pressed down into the sliding socket mechanism by insertion. At this time, the rotating shaft 8 is inserted into the limiting socket 12, and firstly compresses the second spring 14. Then, the inclined groove 11 at the bottom of the rotating shaft 8 will press against the spherical locking parts 17 on both sides, causing the spherical locking parts 17 on both sides to retract inward and compress the two first springs 16. After the rotating shaft 8 is inserted to the bottom, the spherical locking parts 17 on both sides return to their original position and respectively lock into the two annular grooves 10 of the rotating shaft 8, thereby fixing the rotating shaft 8 and realizing the rapid fixing of the methane inlet cover 4.

[0044] During disassembly, the cross-shaped adjusting plate 9 on the methane inlet cover 4 is rotated, causing the rotating shaft 8 to rotate. Then, the edges of the two annular grooves 10 on the rotating shaft 8 come into contact with the spherical retaining parts 17 on both sides. The rotational force causes the spherical retaining parts 17 on both sides to retract back into their original positions. Then, the second spring 14 pops out, driving the rotating shaft 8 to pop out, which can easily complete the disassembly. This facilitates timely cleaning or replacement and effectively prevents blockage caused by impurities in the air, thereby ensuring the long-term stable operation and detection accuracy of the detection alarm.

[0045] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
