Description

Technical Field

[0001] The utility model relates to the technical field of coal mine information collection, in particular to a coal mine internal information collection device. Background Art

[0002] Coal mines are divided into open-pit coal mines and underground coal mines. Underground coal mines are where coal is mined by digging tunnels underground. Coal is a layered solid combustible mineral formed by the transformation of plant remains through complex biochemical and geological processes. The working area where coal is mined inside the coal mine is also called the working face. Before coal miners mine coal from the working face, they need to test the concentration of gas in the working face. Gas refers to the harmful gas mainly composed of coalbed methane in the mine, mainly methane, sometimes referred to as methane alone. Gas is a colorless, tasteless, odorless gas that can burn or explode. It is insoluble in water and has a higher diffusion rate than air. Gas is non-toxic, but when the concentration is very high, it can cause suffocation. Therefore, it is necessary to collect gas concentration information on the working face before work. Since gas can burn or explode, optical gas detectors are usually used inside coal mines to measure gas concentration by using changes in the spectrum in the gas. Compared with other gas concentration detectors, optical gas detectors are more economical and durable in reality.

[0003] Existing gas concentration detectors usually use suction balls to extract gas from various positions on the working face. After extraction, the gas concentration is observed through the gas concentration detector. However, the gas extraction pipe and suction ball and other structures of the gas concentration detector require staff to operate manually, which is inconvenient for staff to observe the extracted gas concentration information at the first time. In addition, the protection of the suction ball is insufficient, and the external suction ball is easily damaged, which affects the normal use of the gas concentration detector and brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a coal mine internal information collection device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1, as Figures 1-4 As shown, a device for collecting information inside a coal mine is shown. When the staff arrives at the working face inside the coal mine, one end of the reaction tube 15 is aimed at the working face to be detected. The staff holds the fixed frame 3 and presses the fixed block 6 to drive the movable plate 4 to rotate in the fixed frame 3. The movable plate 4 drives the movable block 5 through the through hole opened in the installation frame 10 to push the pressure plate 11 to rise in the installation frame 10. The pressure plate 11 rises in the installation frame 10 to squeeze the suction ball 12 in the installation frame 10, thereby compressing the suction ball 12. After being compressed, the suction ball 12 rebounds under the action of its own elastic force. The suction ball 12 is connected to the reaction tube 15 through the connecting pipe 13, so that the suction ball 12 is used to extract the external gas of the working face to be detected and send it into the main body 1 of the optical gas detector to observe and measure the gas concentration, thereby completing the information collection of the gas concentration at the working face inside the coal mine.

[0022] Example 2, as Figure 2 and Figure 4 As shown, a device for collecting information inside a coal mine is provided. After the suction ball 12 is used to shrink and rebound to extract gas from the working surface inside the coal mine, the suction ball 12 pushes the pressure plate 11 back to its original position in the installation frame 10 when it rebounds, so as to facilitate gas extraction next time. At the same time, when the suction ball 12 is compressed by the pressure plate 11 in the installation frame 10 and rebounds itself, the suction ball 12 drives the connecting pipe 13 to slide in the sliding groove provided in the installation frame 10 to prevent the suction ball 12 and the connecting pipe 13 from pulling each other and affecting the suction effect of the suction ball 12. When it is necessary to check the suction ball 12, the rubber limit strip 14 is elastically detached from the rubber limit strip 14 by pulling the installation frame 10. The rubber limit strip 14 no longer limits the installation frame 10, and the installation frame 10 drives The second limiting plate 9 is removed from the fixed frame 3, and the suction ball 12 is pulled to drive the connecting tube 13 out of the installation frame 10, so as to inspect the suction ball 12. After the inspection, the suction ball 12 is placed back on the pressure plate 11 in the installation frame 10, and the connecting tube 13 is installed on the installation frame 10 again through the slide groove opened in the installation frame 10. Then, the installation frame 10 is pulled to drive the suction ball 12 to be placed in the fixed frame 3. The installation frame 10 drives the second limiting plate 9 to be placed under the upper limit installation frame 10 of the first limiting plate 8. Then, the installation frame 10 is pushed to use the elasticity of the rubber limiting strip 14 to make the top of the installation frame 10 close to the bottom of the optical gas detector body 1 again. The rubber limiting strip 14 is used to limit the installation frame 10 to complete the disassembly and assembly of the installation frame 10.

[0023] It should be noted that the utility model is an internal information collection device for coal mines. When in use, the optical gas detector body 1 is driven by the handheld fixed frame 3, which makes it convenient for the staff to extract the gas at the working surface inside the coal mine and then quickly use the optical gas detector body 1 for observation. It is convenient to hold the optical gas detector body 1 while quickly observing the detection results, which is convenient for the staff to operate. After pressing the fixed block 6 to drive the movable plate 4 to push the movable block 5, the fixed block 6 drives the movable plate 4 to press the elastic rubber plate 7 down. When the fixed block 6 loses external pressure, the movable plate 4 at the bottom of the fixed block 6 drives the fixed block 6 to retreat to its original position under the elastic force of the elastic rubber plate 7 itself, and it is convenient to press it next time after resetting.
