[0005] The utility model adopts the technical scheme, a portable underground gas analyzer carrying protective sleeve, including the base cover of the bottom surface and the side surface of the wrapped gas analyzer base, the base cover is connected with the pipe body cover of flexible material, the pipe body cover includes the transition section of lower part and the barrel section of upper part, the barrel section wraps the pipe body of gas analyzer, the transition section gradually narrows from the upper edge of the base cover and connects with the barrel section, the pipe body cover is equipped with the vertical division edge and realizes opening and closing through the closure, the upper edge of the barrel section is provided with the bundle mouth rope that can be tightened upper mouth in circumference, the pipe body cover is opened with the vertical observation port corresponding to the scale of gas analyzer, the observation port is provided with the observation port cover of transparent flexible material, the side surface of the protective sleeve is provided with the telescopic shoulder strap, the pipe body cover and the base cover are internally filled with the buffer material.
[0006] Further, the closure is a zipper or a magic tape.
[0007] Further, a roll edge is provided on the upper edge of the barrel section to pass the binding rope into it.
[0008] Further, the cushioning material is sponge or foam.
[0009] Further, the base sheath is made of leather material, and the barrel sheath is made of canvas material.
[0010] The portable underground gas analyzer carrying protective sleeve has the advantages of convenient carrying, light weight, wear resistance, shock absorption, and drop resistance, and the observation port is convenient for observing readings. The device is convenient for walking when worn by underground workers, and can free both hands when riding a monkey car, so that safety hazards are not easily caused. The device has low manufacturing cost and is convenient to use. After use underground, it can be folded and placed aside, does not occupy space and is not easy to damage, and is easy to repair. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 is a structural schematic view of the utility model.
[0012] In the figure: 1, base sheath; 2, barrel sheath; 21, transition section; 22, barrel section; 23, dividing edge; 24, observation port; 25, binding rope; 3, telescopic shoulder strap. DETAILED DESCRIPTION
[0013] In order to better understand the purpose, structure and function of the utility model, the following will further describe a portable underground gas analyzer carrying protective sleeve of the utility model in combination with the drawings.
[0014] As shown in Figure 1 A portable underground gas analyzer carrying protective sleeve includes a base sheath 1 wrapping the bottom surface and side surface of the base of the gas analyzer, a barrel sheath 2 of flexible material connected to the upper edge of the base sheath 1, the barrel sheath including a lower transition section 21 and an upper barrel section 22, the barrel section 22 wrapping the barrel of the gas analyzer, the transition section 21 gradually narrowing from the upper edge of the base sheath 1 and connecting to the barrel section 22, the barrel sheath 2 being provided with a vertical dividing edge 23 and being opened and closed by a closure, the upper edge of the barrel section 22 being provided with a binding rope 25 that can be tightened, the barrel sheath 2 being provided with a vertical observation port 24 corresponding to the scale of the gas analyzer, the observation port 24 being provided with an observation port sheath of transparent flexible material, the barrel sheath 2 being provided with a telescopic shoulder strap 3, and the barrel sheath 2 and the base sheath 1 being internally padded with a cushioning material.
[0015] In this embodiment, the diameter of the base sheath is 15 cm, the height is 7 cm, the height of the tube sheath 2 is 53 cm, and the diameter of the barrel section is 10 cm. The tube sheath is made of canvas material, and the base sheath is made of leather material. These two materials are not easy to wear and tear and will not generate static electricity, which is suitable for the working environment in the coal mine. The inner pad of the protective sleeve is made of sponge or foam buffer material to play the role of anti-collision and shock absorption, and the underground personnel will not feel uncomfortable. The observation port 24 adopts a transparent PVC soft rubber plate observation port sheath. The coring personnel arrive at the coring site, take the core, and then perform the underground measurement without taking out the analyzer. The scale on the analyzer can be directly observed to effectively avoid the wear and tear of the scale. The closure is made of a zipper or a magic tape, and the barrel section 22 is provided with a rolled edge to pass the binding rope 25 into it. The protective sleeve side uses a telescopic shoulder strap 3, which is convenient for personnel to carry.
[0016] The underground gas analyzer carrying protective sleeve of this embodiment has the advantages of convenient carrying, light quality, wear resistance, shock absorption, and fall prevention. After the surface worker takes out the analyzer, the sponge or foam lining is placed inside the protective sleeve (note that the observation port 24 is not blocked), and then the analyzer is placed inside. The zipper is pulled tight. The side with the scale on the analyzer is moved to the observation port 24. The telescopic shoulder strap 3 can be worn on the shoulder, which can free the hands when riding the monkey car and reduce the occurrence of safety hazards. Even if the telescopic shoulder strap 3 is disconnected or the instrument is accidentally knocked on the coal wall or ironware during walking underground, there is no need to worry, as the built-in sponge or foam can play the role of shock absorption and fall prevention.
[0017] After arriving at the site underground, the operator pulls open the zipper, unscrews the plug of the analyzer base, and fills water to a certain scale. Screw on the plug, insert the rubber tube into the air inlet nozzle of the analyzer base, and connect the air outlet nozzle of the coal sample tank on the other end. After the operation is completed, pull the zipper tight to keep it stable. The binding rope 25 above the barrel section 22 can be hung on the coal wall for underground analysis reading.
[0018] After the underground gas analyzer carrying protective sleeve is made and shaped, it can replace the box brought by the manufacturer, which is convenient to carry. Moreover, the device has low manufacturing cost, is easy to use, can be folded and placed aside after use underground, does not occupy space and is not easy to damage, and is easy to repair. The project can free the hands of miners and reduce safety hazards when put into production and use.
[0019] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the application belong to the scope protected by the utility model.
