Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a gas sampler for mining environment detection with good sealing performance. Background Art

[0002] Although mining provides people with abundant mineral raw materials on the one hand, it also causes serious related environmental pollution on the other hand. Therefore, in order to ensure that the ecological environment will not gradually deteriorate and be destroyed, relevant departments often need to sample and test the air around the mines, so as to take measures in time to prevent, control and maintain the ecological environment of the mining area, so as to restore its original appearance.

[0003] When sampling the air around a mine, a sampler is usually used to collect and detect the air. Although there are many types of existing gas samplers, the existing samplers are not only relatively complex in structure, but some collectors collect air through a single piston cylinder. However, after collecting in this way, the collector is not sealed, which can easily lead to gas leakage, thereby affecting the amount of gas collected, thereby affecting the accuracy of gas detection.

[0004] For this reason, we propose a gas sampler with good sealing performance for mining environment detection. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a gas sampler for mining environment detection with good sealing performance, which overcomes the shortcomings of the prior art and solves the problems in the background technology. However, since the existing samplers are not only relatively complex in structure, but also some collectors collect gas by sucking air through a single piston cylinder, but after collection in this way, the collector is not sealed, which can easily lead to gas leakage, thereby affecting the amount of gas collected, thereby affecting the accuracy of gas detection.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas sampler for mining environment detection with good sealing performance, comprising a sampler body, a piston push movably installed on the inner surface of the sampler body, an air pipe fixedly installed on the left surface of the sampler body, a rubber ring fixedly connected to the outer surface of the air pipe, a cap movably sleeved on the outer surface of the air pipe, an air valve ball fixedly connected to the outer surface of the air pipe, a sealing circular plate rotatably arranged on the inner surface of the air valve ball, a rotating rod rotatably arranged on the upper surface of the air valve ball, two sliding rods movably inserted on the upper surface of the rotating rod, a pull plate fixedly connected to the upper surfaces of the two sliding rods, and four slots are provided on the upper surface of the air valve ball.

[0009] Preferably, a plurality of limit grooves are provided on the outer surface of the piston pusher, a fixed plate is fixedly connected to the right surface of the sampler body, a limit rod is movably inserted on the front surface of the fixed plate, a baffle is fixedly connected to the front surface of the limit rod, and two springs are fixedly connected between the rear surface of the baffle and the front surface of the fixed plate.

[0011] Preferably, the two slide bars are correspondingly engaged with the four slots, and the upper surface of the rotating rod is provided with a first slot hole which is slidably arranged corresponding to the two slide bars.

[0012] Preferably, the limiting rod and the limiting groove are correspondingly engaged with each other, and a second slot hole which is slidably arranged corresponding to the limiting rod is formed on the front surface of the fixing plate.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a gas sampler for mining environment detection with good sealing performance, which has the following beneficial effects:

[0015] 1. The gas sampler for mining environment detection with good sealing performance can collect gas through the coordination of the sampler body, piston push, air pipe, rubber ring, cap, air valve ball, sealing round plate, rotating rod, sliding rod, pull plate, card slot and other structures.

The structure is light, easy to carry, and improves the flexibility of the equipment.

[0016] 2. The gas sampler for mining environment detection has good sealing performance. Through the coordination of limit grooves, fixed plates, limit rods, baffles, springs and other structures, the piston of the collector can be pushed into the limit position after being pulled out for use, to avoid the piston being pushed and moved due to accidental contact, which causes the internal gas to be chaotically stressed and leaked.

[0027] Specifically, the rotating rod 8 can drive the sealing disc 7 to rotate in the air valve ball 6, so as to seal or open the air pipe 3, and the sealing opening and closing can be directly completed through convenient operation.

[0028] In this embodiment, the two slide bars 9 are correspondingly engaged with the four slots 11 , and the upper surface of the rotating rod 8 is provided with a first slot hole correspondingly slidably arranged with the two slide bars 9 .

[0029] Specifically, the sliding rod 9 is engaged with the corresponding two slots 11 to limit the rotation rod 8, so that the rotation rod 8 drives the sealing circular plate 7 to rotate to a specified angle and then fix it to avoid deviation.

[0030] Working principle: When it is necessary to collect the surrounding air for detection in the working area of ​​the mine, take out the sampler body 1 carried with you, and then pull the pull plate 10 to drive the two slide bars 9 to move upward horizontally through the first slot on the rotating rod 8. When the bottom of the slide bar 9 is out of the lower slot 11, then rotate the rotating rod 8 together with the pull plate 10 and the slide bar 9 ninety degrees, and lower the slide bar 9 at the corresponding position together with the pull plate 10, so that the slide bar 9 is engaged with the slot 11 at the corresponding position, and the rotating rod 8 is limited, so that the sealing circular plate 7 in the air valve ball 6 is driven by the rotating rod 8 to rotate ninety degrees, so that the sealing circular plate 7 is longitudinally located in the air valve ball 6, and then the cap 5 is pulled off the air pipe 3, and the piston pusher 2 can be pulled to extract the surrounding air quantitatively, and then the pull plate 10 is pulled to drive the slide bar 9 out of the slot 11, and then Reverse the rotating rod 8 by 90 degrees, engage the sliding rod 9 with the corresponding slot 11, and then rotate the rod 8 to reverse the sealing circular plate 7 by 90 degrees, so that the sealing circular plate 7 is horizontally in the air valve ball 6, thereby sealing and blocking the air valve ball 6 and the air pipe 3, and then limit the sealing circular plate 7 and the rotating rod 8 by engaging the sliding rod 9 with the slot 11, and then put the cap 5 on the end of the air pipe 3, and increase the friction by cooperating with the rubber ring 4 on the surface of the air pipe 3 to firmly cover it, thereby performing double sealing on the collector body and improving the sealing efficiency. When the collected gas needs to be detected later, the cap 5 is removed, the air pipe 3 is connected to the gas detection equipment, and then the sealing circular plate 7 is placed horizontally in the air valve ball 6, thereby pushing the piston push 2 to transport the gas to the inspection equipment for gas detection.

[0031] Embodiment 2

[0037] Working principle: After the collector body is used to collect gas from the mine, the piston pusher 2 is pulled during collection, and at the same time, the baffle 15 is pulled to drive the limit rod 14 to move forward through the second slot on the fixed plate 13, and the limit rod 14 is separated from the limit slot 12 on the piston pusher 2. The baffle 15 cooperates with the fixed plate 13 to stretch the springs 16 on both sides, and then the piston pusher 2 is pulled to extract the gas into the collector body, and then the piston pusher 2 is pulled to calibrate the limit slot 12 closest to the outside of the collector body to correspond horizontally with the limit rod 14, and then Loosen the baffle 15, and the baffle 15 drives the limit rod 14 to return to its original position through the second slot hole on the fixed plate 13 through the elastic force of the spring 16, and then the limit rod 14 is engaged with the limit slot 12 at the specified position of the piston push 2, so as to avoid the piston push 2 from accidentally touching and pushing or pulling, thereby affecting the gas flow in the collector. When the gas needs to be put into the specified gas detection equipment, pull the baffle 15 to drive the limit rod 14 to disengage from the limit slot 12 on the piston push 2, so as to push the piston push 2 to transport the gas in the collector body to the gas detection equipment.
