Abstract
Description
Technical Field
[0001] This utility model relates to a carbon dioxide detection alarm, specifically an integrated laser methane carbon dioxide detection alarm. Background Technology
[0002] In underground coal mines and other hazardous work scenarios where explosive gases such as methane mixtures and coal dust are present, methane leaks or excessive carbon dioxide concentrations can easily lead to major safety accidents such as explosions and asphyxiation. Traditional fixed gas monitoring equipment is difficult to cover the entire range of miners' mobile operations and cannot respond in real time to changes in gas concentration in local areas. Therefore, gas alarms with portability and real-time early warning functions have become the core equipment for ensuring operational safety.
[0003] The existing alarm device mainly consists of a protective housing, a high-precision laser methane / carbon dioxide element, and an integrated circuit board. During operation, methane and carbon dioxide contact the corresponding laser element through a dedicated channel and are converted into weak electrical signals. After the signals are amplified and filtered by the motherboard, they are processed by the microcontroller and the concentration is digitally displayed. If the concentration exceeds the preset threshold, an audible and visual alarm is activated. This device is suitable for miners to carry with them. After going down the mine, it can monitor the concentration of methane and other gases in the surrounding area in real time, provide timely warnings to avoid the risk of exceeding limits, and ensure the safety of personnel underground.
[0004] The existing alarm device has a data transmission interface and a charging interface at the bottom. This design avoids the operation and gripping area, reduces bumps and dust and water erosion, and is suitable for the underground environment. The data transmission interface can interact in two directions, exporting historical monitoring data and connecting to the host computer to update firmware and adjust thresholds. The charging interface is compatible with underground chargers, supports fast charging and has reverse charging and overcurrent protection. This design takes into account both the convenience of operation and maintenance and the lifespan of the interface.
[0005] Currently, handheld alarm devices used in underground coal mines mostly employ a fixed, exposed design or a simple dust plug for their data transmission and charging interfaces, which has certain drawbacks. The fixed, exposed interfaces are constantly exposed to the high concentration of coal dust, humidity, and even corrosive environments underground, making them prone to poor contact due to blockage by foreign objects or corrosion, affecting the reliability and service life of the equipment. In addition, while the design of the interface being recessed into the body improves protection to some extent, it sacrifices ease of use. Connecting cables is often time-consuming and laborious due to limited operating space and obstructed vision, failing to meet the urgent needs of efficient and safe underground operations. Utility Model Content
[0006] The purpose of this invention is to provide an integrated laser methane and carbon dioxide detector and alarm to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An integrated laser methane and carbon dioxide detector alarm includes an alarm body, a methane and carbon dioxide detection element and a button area disposed on the alarm body. The bottom of the alarm body has a first sliding cavity and a second sliding cavity. A sliding protective component is slidably mounted on the first sliding cavity. The sliding protective component and the opening and closing component slidably mounted on the second sliding cavity are in a compression fit. A connecting seat and a rotating adjustment component rotatably mounted on the connecting seat are fixedly installed inside the alarm body. An interface lifting component is slidably mounted on one end of the rotating adjustment component. The interface lifting component is slidably mounted on the bottom of the alarm body.
[0009] As described above, the integrated laser methane and carbon dioxide detector alarm includes a sliding protective assembly comprising a sliding cover plate slidably mounted on the first sliding cavity and an elastic buckle connected to one end of the sliding cover plate. The elastic buckle engages with a slot formed on one side of the first sliding cavity, and two push rods are connected to one side of the sliding cover plate.
[0010] The integrated laser methane and carbon dioxide detector alarm as described above: the opening and closing assembly includes an opening and closing plate slidably mounted on the second sliding cavity and two square tubes connected to one side of the opening and closing plate. One end of each of the two square tubes is connected to a spring, and the spring abuts against one end of the second sliding cavity.
[0011] The integrated laser methane and carbon dioxide detector alarm as described above: the rotary adjustment component includes a shaft rotatably mounted on the connecting seat and a surrounding groove opened in the axial direction of the shaft, and a rotary handle is connected to the bottom of the shaft.
[0012] As described above, the integrated laser methane and carbon dioxide detector alarm includes an interface lifting assembly comprising a round rod slidably mounted on the surrounding groove and a lifting seat connected to one end of the round rod. The lifting seat has multiple positioning holes, which are inserted into guide posts connected to the alarm body.
[0013] As described above, the integrated laser methane and carbon dioxide detector alarm has a charging interface and a data transmission interface connected to the bottom of the lifting base, both of which are compatible with the sliding cover.
[0014] As described above, the integrated laser methane and carbon dioxide detector alarm has the rotating handle positioned above the second sliding cavity, and the rotating handle cooperates with the opening and closing plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] The alarm integrates a liftable data transmission and charging interface at its bottom, and innovatively adopts a sliding cover structure. When not in use, the cover can completely seal the bottom, effectively preventing the intrusion of foreign objects such as coal dust and moisture in the coal mine, thus improving the protection level of the interface. When it is necessary to connect cables, simply slide the cover, and its linkage mechanism will automatically push open the side opening plate to reveal the internal rotating handle. By rotating this handle, the data transmission and charging interface can be precisely controlled to extend smoothly from the inside of the device. This lifting mechanism not only provides ample space for plugging and unplugging operations, effectively avoiding interface damage caused by limited operating space, but also greatly improves the convenience of connection in dim and complex underground environments.
[0017] This utility model, through its integrated structure of protection, operation, and storage, not only enhances the interface's resistance to pollution and damage in response to the characteristics of the underground environment, but also optimizes the operating experience through a user-friendly linkage and lifting design. It effectively ensures the continuous stability of the alarm interface function, providing strong support for the reliable operation of the equipment underground and the efficient operation of miners.

[0028] 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.
[0029] Please see Figures 1-9 As an embodiment of this utility model, the integrated laser methane and carbon dioxide detector alarm includes an alarm body 1, a methane and carbon dioxide detection element 2 and a button area 3 disposed on the alarm body 1. The bottom of the alarm body 1 is provided with a first sliding cavity 4 and a second sliding cavity 5. A sliding protective component is slidably installed on the first sliding cavity 4. The sliding protective component and the opening and closing component slidably installed on the second sliding cavity 5 are in a compression fit. A connecting seat and a rotating adjustment component rotatably installed on the connecting seat are fixedly installed inside the alarm body 1. An interface lifting component is slidably installed at one end of the rotating adjustment component. The interface lifting component is slidably installed at the bottom of the alarm body 1.
[0030] In this embodiment, through the sealing and protection function of the sliding protective component, when the interface is not in use, the cover plate can be precisely slid to the bottom of the interface to form a fully enclosed protection, which can effectively prevent high concentrations of coal dust, water, and gravel particles from entering the interface from underground. This avoids poor contact and short circuit failures caused by the accumulation of contaminants in traditional fixed interfaces, significantly reduces the frequency of interface maintenance, extends the service life of core interfaces, and ensures the reliability of the interface in complex environments. Secondly, the linkage design of the sliding protective component and the opening and closing component improves the ease of operation. When the interface needs to be used, simply moving the cover plate to one side will simultaneously push the opening and closing component to one side, exposing the interface without additional operation. The rotary adjustment component simplifies the operation steps when wearing heavy protective gloves underground, reduces the range of hand movements, and adapts to the operation scenarios in narrow underground spaces. Finally, the interface lifting component can be raised and lowered by rotating the adjustment component. The interface lifting structure driven by rotating the handle 12 solves the pain point of traditional interfaces being deeply hidden inside the equipment and inconvenient for plugging and unplugging cables. By rotating the handle 12, the interface can be extended from inside the equipment to a suitable length, which not only makes it easier for miners to quickly align the cable connector and avoids difficulties in plugging and unplugging due to obstructed vision or insufficient operating space, but also allows the interface to be retracted into the equipment after use, further strengthening the storage and protection of the interface and preventing accidental bumps and damage when idle.
[0031] As a further embodiment of this utility model, the sliding protection assembly includes a sliding cover plate 6 slidably mounted on the first sliding cavity 4 and an elastic buckle 7 connected to one end of the sliding cover plate 6. The elastic buckle 7 engages with a slot formed on one side of the first sliding cavity 4, and two push rods 8 are connected to one side of the sliding cover plate 6.
[0032] In this embodiment, firstly, through the sealing and protection function of the sliding cover plate 6, when the interface is not in use, the sliding cover plate 6 can be precisely slid to the bottom of the interface to form a fully enclosed protection, which can effectively isolate the intrusion of high concentrations of coal dust, water and gravel particles in the well into the interface, avoid poor contact and short circuit failure caused by the accumulation of pollutants in traditional fixed interfaces, greatly reduce the frequency of interface maintenance, extend the service life of core interfaces, and ensure the reliability of the interface of the equipment in complex environments.
[0033] As a further embodiment of this utility model, the opening and closing assembly includes an opening and closing plate 9 slidably mounted on the second sliding cavity 5 and two square tubes 10 connected to one side of the opening and closing plate 9. One end of each of the two square tubes 10 is connected to a spring 11, and the spring 11 abuts against one end of the second sliding cavity 5.
[0034] In this embodiment, simply sliding the cover plate 6 will automatically push open the side opening and closing plate 9 with the push rod 8 on one side, and at the same time, the opening and closing plate 9 will drive the two square tubes 10 to compress the two springs 11.
[0035] As a further embodiment of this utility model, the rotary adjustment assembly includes a shaft 13 rotatably mounted on the connecting seat and a surrounding groove 14 formed in the axial direction of the shaft 13, and a rotary handle 12 is connected to the bottom of the shaft 13.
[0036] In this embodiment, after the sliding cover 6 pushes open the opening and closing plate 9, the internal rotating handle 12 is exposed. The shaft 13 rotates synchronously with the rotating handle 12. A surrounding groove 14 is formed on the shaft 13. The surrounding groove 14 is designed in a surrounding manner.
[0037] As a further embodiment of this utility model, the interface lifting assembly includes a round rod 15 slidably mounted on the surrounding groove 14 and a lifting seat 16 connected to one end of the round rod 15. The lifting seat 16 is provided with a plurality of positioning holes, which are inserted into guide posts connected to the alarm body 1.
[0038] In this embodiment, the round rod 15 is slidably mounted on the surrounding groove 14 on the shaft 13, the lifting seat 16 moves synchronously with the round rod 15, and the guide column provides stable guidance for the lifting of the lifting seat 16.
[0039] As a further embodiment of this utility model, the bottom of the lifting seat 16 is connected to a charging interface 17 and a data transmission interface 18, both of which cooperate with the sliding cover plate 6.
[0040] In this embodiment, a charging interface 17 and a data transmission interface 18 are provided at the bottom of the lifting seat 16. The data transmission interface 18 can interact bidirectionally, and the charging interface 17 is compatible with a dedicated underground charger.
[0041] As a further embodiment of this utility model, the rotating handle 12 is disposed on the second sliding cavity 5, and the rotating handle 12 cooperates with the opening and closing plate 9.
[0042] In this embodiment, by rotating the handle 12, the shaft 13 is rotated. When the shaft 13 rotates, the round rod 15 slides on the surrounding groove 14 at one end of the shaft 13. When the shaft 13 rotates, the round rod 15 slides up and down on the surrounding groove 14. The round rod 15 moves synchronously with the lifting seat 16. By rotating the handle 12, the interface can be extended from inside the equipment to a suitable length. This not only makes it easier for miners to quickly align the cable connector and avoids difficulties in plugging and unplugging due to obstructed vision or insufficient operating space, but also allows the interface to be retracted into the equipment after use, further strengthening the storage and protection of the interface and preventing accidental damage when idle.
[0043] 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.
