Description

Technical Field

[0001] This utility model relates to the field of oxygen sensor technology, and more specifically, to a general-purpose oxygen sensor for mining applications. Background Technology

[0002] In underground mining operations such as coal and metal mining, the underground environment is complex and changeable, making oxygen concentration monitoring a crucial link in ensuring the safety of miners' lives and production. Mines pose risks such as gas explosions and oxygen deprivation leading to asphyxiation; accurate and real-time oxygen concentration data helps workers to provide timely warnings and take appropriate measures.

[0003] When using oxygen sensors in mines, unstable air pipe connections are common, often loosening and falling off, leading to poor gas transmission and affecting the accuracy of oxygen concentration monitoring. At the same time, the abundance of dust and particulate matter in mines makes the air pipe interfaces and internal structures of the sensors susceptible to contamination, resulting in frequent airway blockages and component jamming, which shortens the lifespan of the sensors and increases maintenance costs.

[0004] Therefore, it is necessary to redesign the general-purpose oxygen sensor for mining to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a general type oxygen sensor for mining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A general-purpose oxygen sensor for mining includes a sensor body with two gas pipe interfaces on each side. Two fixing blocks are symmetrically fixed on each side of the sensor body. Each fixing block has a mounting groove on one side. A threaded rod is mounted on the inner wall of each mounting groove via a bearing. Each threaded rod is threadedly connected to a slider, which slides within the corresponding mounting groove. A connecting frame is fixedly connected to one side of each slider. Each connecting frame has a fixing groove and a protective device within each fixing groove. A clamping plate is fixedly mounted on each connecting frame.

[0008] In a preferred embodiment, each of the protective devices includes a spring, which is fixedly connected to the inner wall of the fixing groove. One end of the spring is fixedly connected to a mounting plate, which is slidably connected in the fixing groove at a corresponding position. One end of the mounting plate is fixedly connected to a baffle.

[0009] In a preferred embodiment, a rubber pad is fixedly installed on each of the clamps.

[0010] In a preferred embodiment, each of the sides is rotatably mounted with a handle, and the handle rotates through one side of the fixing block and is fixedly connected to one end of the threaded rod corresponding to the position.

[0011] In a preferred embodiment, an elastic protective membrane is fixedly connected to the inner walls on both sides of each mounting groove, and one end of the two elastic protective membranes located in the same mounting groove is fixedly connected to both sides of the slider.

[0012] In a preferred embodiment, the two tracheal inlets are located in the middle of two fixing blocks on the same side.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a threaded rod, slider, connecting frame, clamping plate and other devices. The threaded rod drives the slider to move the connecting frame and clamping plate, so that the clamping plate and rubber pad fix the gas pipe. This can effectively prevent the gas pipe from loosening or falling off and ensure that the mine gas is stably transmitted to the inside of the sensor.

[0015] 2. This utility model, by setting up protective devices and elastic protective membranes, can effectively block a large amount of dust and particulate matter in the mine from entering the sensor when the baffle is not in operation, thereby reducing the risk of air blockage and component contamination. The elastic protective membrane can protect the mounting groove, preventing dust from entering the mounting groove and causing the threaded rod to jam.

[0016] In summary, this utility model is simple to operate. The threaded rod drives the slider, which in turn moves the connecting frame and clamping plate. The rubber pad secures the air pipe, preventing it from loosening and falling off, thus ensuring stable gas transmission in the mine. When not in operation, the baffle seals the air pipe interface, blocking dust and particles and reducing airway blockage and component contamination. The elastic protective film protects the mounting groove, preventing dust from entering and causing the threaded rod to jam, effectively improving the sensor's operational stability and service life.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-5 A general-purpose oxygen sensor for mining includes a sensor body 1. Two air pipe interfaces 3 are provided on each side of the sensor body 1. Two fixing blocks 2 are symmetrically fixed on each side of the sensor body 1. The two air pipe interfaces 3 are located in the middle of the two fixing blocks 2 on the same side. Each fixing block 2 has a mounting groove 10 on one side. A threaded rod 11 is mounted on the inner wall of each mounting groove 10 via a bearing. Each threaded rod 11 is threadedly connected to a slider 12, which is slidably connected within the corresponding mounting groove 10. A connecting frame 6 is fixedly connected to one side of each slider 12. Each connecting frame 6 has a fixing groove 13, and a protective device is provided within each fixing groove 13. A clamping plate 4 is fixedly installed on each connecting frame 6.

[0025] Each protective device includes a spring 14, which is fixedly connected to the inner wall of the fixing groove 13. One end of the spring 14 is fixedly connected to a mounting plate 15, which is slidably connected in the corresponding fixing groove 13. One end of the mounting plate 15 is fixedly connected to a baffle 7. Under the elastic force of the spring 14, the baffle 7 can tightly seal the air pipe interface 3, forming a physical barrier to effectively prevent a large amount of dust, particulate matter and other impurities in the mine from entering the air pipe interface 3, preventing air blockage and contamination of the internal components of the sensor by impurities.

[0026] Each clamp 4 is fixedly equipped with a rubber pad 5. The rubber pad 5 has good elasticity and friction, which can provide sufficient pressure when clamping the trachea to prevent the trachea from loosening or falling off and ensure stable gas transmission; it can also avoid damage to the surface of the trachea, protect the integrity of the trachea, and extend its service life.

[0027] Each of them has a handle 9 rotatably mounted on one side, and the handle 9 rotatably passes through one side of the fixing block 2 and is fixedly connected to one end of the threaded rod 11 corresponding to the position.

[0028] Each mounting groove 10 has an elastic protective membrane 8 fixedly connected to the inner walls on both sides. One end of each of the two elastic protective membranes 8 located within the same mounting groove 10 is fixedly connected to both sides of the slider 12. During the sliding of the slider 12, the elastic protective membrane 8 can stretch or contract accordingly, maintaining the sealing state of the mounting groove 10 at all times. This not only prevents dust and moisture from entering the mounting groove 10, but also avoids problems such as jamming of the threaded rod 11 and other components due to dust accumulation.

[0029] In use, the gas tube for gas transmission is connected to the gas tube interfaces 3 on both sides of the sensor body 1. Then, the handle 9 is rotated, causing the threaded rod 11 to rotate within the mounting groove 10 of the fixing block 2. The rotation of the threaded rod 11 causes the threaded slider 12 to slide within the mounting groove 10. The slider 12 is linked to the clamping plate 4 via the connecting bracket 6, thereby clamping and fixing the gas tube between the clamping plate 4 and the gas tube interface 3. The rubber pad 5 on the clamping plate 4 increases friction, which not only stabilizes the gas tube but also prevents damage to the gas tube surface during clamping, ensuring a tight connection of the gas tube interface 3 and stable gas transmission.

[0030] During sensor downtime or transportation, the baffle 7 plays a crucial protective role. When the sensor is not in operation, the baffle 7, under the elastic force of the spring 14, seals the air pipe interface 3, forming a physical barrier to prevent dust, particulate matter, and other impurities in the mine from entering the air pipe interface 3, thus preventing air blockage or interference from impurities with the internal sensing elements. When the sensor is working normally, external air pressure or manual operation can cause the baffle 7 to overcome the elastic force of the spring 14 and move into the fixed groove 13, exposing the air pipe interface 3, allowing gas to smoothly enter the sensor.

[0031] External gas enters the sensor body 1 through the gas pipe interface 3, comes into contact with the core electrochemical sensing element, and undergoes an electrochemical reaction to generate an electrical signal proportional to the oxygen concentration. After amplification and analog-to-digital conversion, the processor inside the sensor calculates the oxygen concentration value, displays it in real time on the screen, and simultaneously outputs the data to the monitoring system in standard signal form, realizing real-time monitoring of oxygen concentration in the mine environment.

[0032] The elastic protective membrane 8 on both sides of the inner wall of the mounting groove 10 is connected to the slider 12. When the slider 12 slides in the mounting groove 10, the elastic protective membrane 8 stretches or contracts accordingly, always keeping the inside of the mounting groove 10 sealed, preventing dust from entering the sensor and affecting the normal operation of components such as the clamping plate 4 and the threaded rod 11, ensuring the stability of the sensor structure and extending its service life.
