Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to a gas detection device for underground mines. Background Technology

[0002] In underground mining operations, the working environment is complex and dangerous, with gas safety issues being particularly prominent. These gases not only pose a serious threat to the life and health of miners, but may also cause major safety accidents such as explosions and poisoning, resulting in huge losses to mining production. Therefore, it is necessary to use gas detection devices to detect ambient air during underground mining. However, existing underground mining gas detection devices still have certain shortcomings in their use.

[0003] A portable mining gas detection device, as proposed in application number CN201821093173.2, includes a main body. A probe and a light are mounted sequentially from left to right on the top of the main body. A camera is mounted on the upper front of the main body, and a display screen is mounted below the camera. A constant green indicator light and a hazard indicator light are arranged sequentially from top to bottom on one side of the main body near the display screen. A speaker is mounted below the display screen, and function buttons are located below the speaker. A battery compartment is located at the bottom of the main body. A back clip mounting base is mounted on the upper back of the main body, and a back clip is mounted downwards on the back clip mounting base. The clamping plate below the back clip is tightly attached to the bottom back of the main body. In actual use, although the probe is protected by a cover, the display screen is exposed, making it prone to wear and tear, reducing the protective effect. Furthermore, after the probe cover is removed, it needs to be stored separately, which can easily lead to loss.

[0004] Therefore, we propose an underground mine gas detection device to solve the problems mentioned above. Utility Model Content

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an underground mine gas detection device, comprising a detection body 1, with detection probes 2 for gas detection symmetrically installed on the top of the detection body 1, a left protective plate 3 on the top left side of the detection body 1, and a right protective plate 4 on the top right side of the detection body 1. Screen protective plates 5 are fixedly installed on the bottom front sides of the left and right protective plates 3 and 4. A telescopic sliding mechanism connects the left and right protective plates 3 and 4 to the top of the detection body 1. The telescopic sliding mechanism includes sliding plates symmetrically opened on the top of the detection body 1. Slide seats 7 are symmetrically installed on the inner sides of groove 6, left guard plate 3 and right guard plate 4. Left guard plate 3 and right guard plate 4 are slidably connected to groove 6 through slide seats 7. The telescopic sliding mechanism also includes positioning plates 8 symmetrically installed on the top of the detection body 1. Movable rods 9 are symmetrically installed inside left guard plate 3 and right guard plate 4. Movable rods 9 are slidably connected to positioning plates 8 through them. A first spring 10 is sleeved on the outer ring of the movable rods 9 between the two side positioning plates 8 and left guard plate 3 and right guard plate 4. Left guard plate 3 and right guard plate 4 are telescopically connected to positioning plates 8 through the first spring 10.

[0031] The design of the above structure allows the left and right protective plates 3 and 4 to slide inward through the slide block 7 within the slide groove 6 by pressing them inward. This facilitates the docking and closure of the left and right protective plates 3 and 4, as well as the screen protective plate 5, which is beneficial for protecting the detection probe 2 and the display screen of the detection body 1. The first spring 10 can work with the positioning plate 8 to push the left and right protective plates 3 and 4, allowing them to slide and separate within the positioning plate 8 in conjunction with the movable rod 9. This also causes the screen protective plates 5 on both sides to separate, exposing the detection probe 2 and the display screen of the detection body 1 for gas detection.

[0032] The top of the left guard plate 3 and the right guard plate 4 are equipped with a locking and positioning mechanism. The locking and positioning mechanism includes a positioning rod 11 fixedly installed on the top surface of the left guard plate 3. The outer ring of the positioning rod 11 is rotatably sleeved with a locking plate 12. The outer ring of the positioning rod 11 at the top of the locking plate 12 is sleeved with a second spring 13. A pull buckle 14 is fixedly installed on the top surface of the locking plate 12 away from the positioning rod 11. The top of the right guard plate 4 is provided with a locking groove 15, which is movably locked and connected with the locking plate 12.

[0033] The above-mentioned structure is designed so that the snap-fit ​​plate 12 can be raised and lowered on the outer ring of the positioning rod 11 by utilizing the extension and retraction of the second spring 13 and the control of the snap-fit ​​groove 15. When the left guard plate 3 and the right guard plate 4 are slidably closed, it is convenient to use the snap-fit ​​to achieve positioning. When they are separated, it is convenient to separate the left guard plate 3, the right guard plate 4 and the screen guard plate 5, thereby facilitating the use of the underground mine gas detection device.

[0034] A hooking mechanism is fixedly installed on the back of the testing machine body 1. The hooking mechanism includes a hook 16 fixedly installed on the back of the testing machine body 1. A limit groove 17 is opened inside the hook 16. A rotating seat 18 is provided inside the limit groove 17. A connecting rod 19 is fixedly installed at the bottom end of the rotating seat 18. Bearings 20 are sleeved on both ends of the connecting rod 19. The outer ring of the bearings 20 is fixedly connected to the hook 16. A fixing plate 21 is fixedly installed on both ends of the connecting rod 19. A torsion spring 22 is sleeved on the outer ring of the connecting rod 19 between the fixing plate 21 and the hook 16. The two ends of the torsion spring 22 are fixedly connected to the hook 16 and the fixing plate 21. The connecting rod 19 and the fixing plate 21 form a rotation and reset structure with the hook 16 through the torsion spring 22.

[0035] The above-described structure is designed so that when the underground mining gas detection device is hung on the belt via the hook 16, the belt will compress the rotating seat 18, causing the rotating seat 18 to rotate via the connecting rod 19 and the bearing 20 and retract into the limiting groove 17. Then, when the belt is fully inside the hook 16, the torsion spring 22 will work with the fixing plate 21 to drive the connecting rod 19 and the rotating seat 18 to rotate and reset, thereby closing the opening of the hook 16 and achieving stable mounting of the underground mining gas detection device.

[0036] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
