Description

Technical Field

[0001] This utility model belongs to the field of coalbed methane content determination technology, specifically relating to an automatic coalbed methane content determination device with an anti-hand slippage structure. Background Technology

[0002] In coal mining and other operations involving coal seams, the coal seams typically contain a certain concentration of methane gas. Since methane is a flammable and explosive gas, exceeding safety thresholds can easily lead to explosions, poisoning, and other serious accidents. Therefore, accurately measuring the methane gas content in the coal seams at the work site is a crucial step in ensuring operational safety.

[0003] However, in the current operating mode, after the measurement is completed, workers often hold the testing instrument temporarily in their hands. While this practice seems convenient, it brings many inconveniences to subsequent work. When both hands are busy with complex operations and it's difficult to keep the instrument under control, the device can easily slip from the hands. Once the testing instrument falls, it may not only be damaged, affecting subsequent gas monitoring, but it may also collide with other equipment or coal seams during the fall, generating sparks. This is undoubtedly a significant safety hazard in a working environment containing methane gas. Utility Model Content

[0004] The purpose of this invention is to provide an automatic coalbed methane content measuring device with an anti-slip structure, aiming to solve the problem that the device can easily slip from the hands when both hands are busy with complex operations. Once the measuring instrument falls, it may not only be damaged, affecting subsequent gas monitoring, but it may also collide with other equipment or coal seams during the fall, generating sparks. This is undoubtedly a major safety hazard in working environments containing methane gas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic coalbed methane content measuring device with an anti-hand slip structure, including a methane detector, a collar sleeved on the outer wall of the methane detector, an upper clip attached to one side of the outer wall of the collar, and a lower clip attached to the collar below the upper clip. One end of the connecting strap is inserted into the gap between the upper and lower clips, and the other end of the connecting strap is sewn onto the outer wall of the male-female adhesive side.

[0006] In order to fix one end of the connecting strip in the gap between the upper and lower clamping plates, as the automatic coalbed methane content measuring device with anti-detachment structure of this utility model, preferably, four upper inserts are bonded at equal intervals on the outer wall of the opposite side of the upper and lower clamping plates, the bottom of the upper inserts is inserted into the interior of the lower positioning plate, and the bottom of the lower positioning plate is bonded to the outer wall of the lower clamping plate. The connecting strip has four equally spaced slots at one end, and the connecting strip is connected to the insert post and the lower positioning piece through the slots.

[0007] To ensure a more stable connection between the lower and upper clamping plates, the automatic coalbed methane content measuring device with an anti-detachment structure of this invention preferably has two blocks symmetrically bonded to the outer wall of the lower clamping plate near the collar. The top of the blocks contacts the bottom of the upper clamping plate, and one side of the blocks is in movable contact with one end of the connecting belt. A fastening piece is rotatably installed on each of the two outer walls of the upper clamping plate away from the end that connects with the collar. A fastening hole is opened through the other outer wall of the fastening piece.

[0008] A buckle post is glued to each of the two outer walls of the lower clip away from the end that mates with the collar. The end of the buckle post is larger than the diameter of the horizontal end. The buckle hole passes through the end of the buckle post and fits onto the outer wall of the horizontal end of the buckle post.

[0009] Compared with the prior art, the beneficial effects of this utility model are: To use, place the collar on the outer wall of the methane detector, then push one end of the upper clip upwards. This increases the gap between the upper and lower clips, allowing the connector end to be inserted into the corresponding lower positioning piece on the lower clip. Release the upper clip to reset it, causing the upper clip to move the upper pin through the insertion point and into the corresponding lower positioning piece. Then, align the fasteners on both sides of the upper clip with the fasteners on the lower clip, securing one end of the connector between the upper and lower clips. Secure the connector to the user's palm; this prevents the methane detector from falling to the ground even when the user opens their hand, thus preventing it from slipping off.

[0014] 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.

[0015] Please see Figure 1-3 The present invention provides the following technical solution: an automatic coalbed methane content measuring device with an anti-hand slip structure, including a methane detector 1, a collar 2 sleeved on the outer wall of the methane detector 1, an upper clamping piece 3 glued to one side of the outer wall of the collar 2, and a lower clamping piece 4 glued to the collar 2 below the upper clamping piece 3. The methane detector 1 employs TDLAS laser spectroscopy technology. The instrument incorporates a modulated semiconductor laser diode that emits near-infrared laser light of a specific wavelength. When the laser passes through the detection chamber, if methane is present in the environment, methane molecules will absorb a portion of the specific wavelength of laser light. The absorption intensity is directly proportional to the methane concentration. By modulating the laser wavelength and comparing the signal differences between two detections, the instrument eliminates interference factors such as background light and dust, accurately calculating the methane concentration. For more details, please refer to: SFT's handheld mini laser methane detector.

[0016] When in use, staff can remotely measure the methane gas content in the coal seam using the methane detector 1. This allows them to obtain specific data on the methane gas in the coal seam, thereby ensuring the safety of workers.

[0017] One end of the connecting band 5 is inserted into the gap between the upper clip 3 and the lower clip 4, and the other end of the connecting band 5 is sewn onto the outer wall of one side of the mortise and tenon joint 6.

[0018] Preferably, four upper inserts 31 are bonded at equal intervals on the outer wall of the opposite side of the upper clamping piece 3 and the lower clamping piece 4. The bottom of the upper inserts 31 is inserted into the interior of the lower positioning piece 41, and the bottom of the lower positioning piece 41 is bonded to the outer wall of the lower clamping piece 4. The connecting strip 5 has four equally spaced slots 51 at one end, and the connecting strip 5 is connected to the upper insertion post 31 and the lower positioning piece 41 through the slots 51.

[0019] In practical use, the upper clamp 3 is made of deformable rubber. When in use, the upper clamp 3 is pushed upwards to make one end of the upper clamp 3 tilt upwards. This increases the distance between the lower clamp 4 and the upper clamp 3, making it easier to install the connecting strap 5 between the lower clamp 4 and the upper clamp 3. When the connecting strap 5 is installed between the upper clamping plate 3 and the lower clamping plate 4, align the four insertion ports 51 at one end of the connecting strap 5 with the lower positioning plate 41 and the stop block 42 so that the connecting strap 5 can be accurately installed on the lower clamping plate 4. Next, loosen the upper clamp 3, which will reset. When the upper clamp 3 resets, it will cause the upper insertion post 31 to be inserted into the socket 51. Then, press the lower clamp 4 and the upper clamp 3 towards the center, so that the upper insertion post 31 is inserted into the lower positioning piece 41.

[0020] Preferably, two blocks 42 are symmetrically bonded to the outer wall of the lower clamping piece 4 near the collar 2. The top of the blocks 42 contacts the bottom of the upper clamping piece 3, and one side of the blocks 42 is in movable contact with one end of the connecting belt 5. A fastener 32 is rotatably installed on the outer walls of the upper clamping piece 3 on both sides away from the end that docks with the collar 2. A fastening hole 33 is opened through the other outer wall of the fastener 32.

[0021] In practical use, after the connecting strap 5 is aligned with the lower clamp 4 and the upper clamp 3, the fastener 32 is then aligned with the fastener post 43. In this way, the lower clamp 4 and the upper clamp 3 can be more stably aligned together, thus ensuring that the connecting strap 5 is securely installed between the lower clamp 4 and the upper clamp 3.

[0022] Preferably, a buckle post 43 is glued to the outer walls of the two sides of the lower clip 4 away from the end that is connected to the collar 2. The end size of the buckle post 43 is larger than the diameter of the horizontal end. The buckle hole 33 passes through the end of the buckle post 43 and fits onto the outer wall of the horizontal end of the buckle post 43.

[0023] Working principle: In use, place the collar 2 on the outer wall of the methane detector 1, and then push one end of the upper clamp 3 upwards. This increases the gap between the upper clamp 3 and the lower clamp 4, allowing the insertion port 51 of the connecting strap 5 to be inserted into the corresponding lower positioning piece 41 on the lower clamp 4. Release the upper clamp 3 to reset it, and the upper clamp 3 will drive the upper insertion post 31 through the insertion port 51 and insert it into the corresponding lower positioning piece 41.

[0024] Then, the buckles 32 on both sides of the upper clip 3 are aligned with the buckle posts 43 on the lower clip 4, so that one end of the connecting strap 5 is securely installed between the upper clip 3 and the lower clip 4. The adhesive tape 6 is then fastened to the user's palm, so that the methane detector 1 will not fall to the ground even if the user opens their palm during use, thus preventing the methane detector 1 from detaching from the palm.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
