Description

Technical Field

[0001] The present invention relates to the technical field of mining gas detection, and in particular to a portable gas detection device. Background Art

[0002] At present, artificial gas detection in coal mines mainly adopts different insertion methods due to the different environments of the gas being detected.

[0003] One environment is the gas at a very high position in an open area. In this environment, a portable detection instrument with an extension rod is used for concentration detection. The problem with this solution is that since it is necessary to detect a very high position, an extension rod is needed to extend the detection height. However, the length of the traditional portable extension rod is inevitably limited, and the highest gas concentration may not be detected because the portable extension rod is not long enough.

[0004] The second environment is the gas in a closed area. In this environment, different gas detection tubes are used in conjunction with gas samplers to detect concentration. However, the problem with this solution is that the detection data may be distorted due to improper operation by employees or failure of the gas detection tube. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a portable gas detection device in view of the above-mentioned technical deficiencies. The portable gas detection device can be used for gas detection at ultra-high positions in open areas as well as gas detection in closed areas. The device is simple to operate and easy to carry, making the measured gas concentration value more accurate.

[0006] The technical solution adopted by the present invention is: to provide a portable gas detection device, including a storage box for storing a portable gas detector; a sealing cover is provided on the storage box; a sealing rubber ring is sleeved and fixed on the sealing cover; the sealing cover is sealed and connected to the storage box through the sealing rubber ring; one end of the storage box is connected to a gas relief component, and the other end is connected to a pipe joint; a suction air bag is provided outside the storage box; the suction air bag is respectively connected to an exhaust joint and an air inlet joint; an exhaust joint is installed with an exhaust check valve; an air inlet check valve is installed on the air inlet joint; the exhaust joint is connected to the pipe joint through an air supply hose; the air inlet joint is connected to an exhaust hose.

[0007] To further optimize the technical solution, a support rod is fixed on the sealing cover of the portable gas detection device; two ends of the support rod are located on opposite sides of the sealing cover; limiting bands are respectively fixedly connected to both ends of the support rod; a limiting sleeve is fixed on the limiting band; elastic bands are respectively fixedly connected to opposite sides of the outer wall of the storage box; a hook is fixed on the elastic band; when the sealing cover seals the storage box, the hook is connected to the limiting sleeve one by one through the stretching of the elastic band.

[0008] To further optimize the technical solution, the outer end interfaces of the pipe joint, exhaust joint and air inlet joint of the portable gas detection device are all stepped structures; the two ends of the air supply hose are respectively plugged into the outer end interfaces of the pipe joint and the exhaust joint; the air exhaust hose is plugged into the outer end interface of the air inlet joint.

[0009] To further optimize the technical solution, the air extraction hose and the air supply hose of the portable gas detection device are both made of silicone tube.

[0010] The beneficial effects of the present invention are:

[0011] The setting of the storage box can facilitate the placement of corresponding detectors according to the needs of detecting different gases, and it has wide universality; the storage box is sealed by the sealing cover and the sealing rubber ring, which can ensure that the gas entering the storage box does not leak out and avoid the mixing of non-detection gases from the outside, meet the detection needs, and ensure the accuracy of detection.

[0012] An outlet check valve is installed on the exhaust connector, and an inlet check valve is installed on the inlet connector. By pressing the suction airbag, the gas to be detected can be drawn in through the exhaust hose and discharged to the storage box through the air delivery hose. This process is made irreversible, ensuring that the gas to be detected can continuously and accurately enter the storage box, thereby improving the efficiency of collecting the gas to be detected and preventing leakage.

[0013] The exhaust hose can be easily set to a longer length while being portable, so as to facilitate the extraction of space gas at ultra-high locations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the portable gas detection device includes a storage box 1 for storing the portable gas detector; a sealing cover 2 is provided on the storage box 1; a sealing rubber ring 3 is sleeved and fixed on the sealing cover 2; the sealing cover 2 is sealed and connected to the storage box 1 through the sealing rubber ring 3; one end of the storage box 1 is connected to a degassing component 4, and the other end is connected to a pipe joint 5; a suction air bag 6 is provided outside the storage box 1; the suction air bag 6 is respectively connected to an exhaust joint 7 and an air inlet joint 8; an exhaust check valve 9 is installed on the exhaust joint 7; an air inlet check valve 10 is installed on the air inlet joint 8; the exhaust joint 7 is connected to the pipe joint 5 through an air supply hose 11; the air inlet joint 8 is connected to an exhaust hose 12.

[0020] The size of the vacuum hose 12 of the present invention can be set according to needs. It only needs to be rolled up and folded when carried without taking up space. Compared with traditional extension rods, the extendable length can be greatly increased while ensuring portability, thereby ensuring that the gas can be extended to the detection position when detecting gas at ultra-high positions in an open area.

[0021] According to the type of gas to be detected and the category of detection data, the corresponding detector can be placed in the storage box 1. After placement, it is sealed by covering the sealing cover 2 and pressing the suction airbag 6. Due to the setting of the air inlet check valve 10 and the air outlet check valve 9, when the suction airbag 6 is pressed, the gas in the airbag is sent into the storage box 1 through the air supply hose 11. After releasing the pressure, the suction airbag 6 draws the gas at the position to be detected through the exhaust hose 12, and this process is irreversible. Therefore, by continuously pressing the suction airbag 6, the gas to be detected can continuously enter the storage box 1 efficiently and accurately, so that the storage box 1 can realize accurate collection of the gas to be detected.

[0022] When a sufficient amount of the gas to be tested is collected in the storage box 1 , accurate data of the gas to be tested can be read out through the detector in the storage box 1 .

[0023] When extracting the gas to be detected, the gas release component 4 can be opened to allow the gas to be detected that continuously enters the storage box 1 to squeeze out the original gas in the storage box 1 until the storage box 1 is filled with the gas to be detected, and then the gas release component 4 is closed, thereby improving the detection accuracy. The gas release component 4 can be a gas release valve or other gas release devices.

[0024] A support rod 13 is fixed on the sealing cover 2; two ends of the support rod 13 are located at opposite sides of the sealing cover 2; two ends of the support rod 13 are respectively fixedly connected with limiting belts 14; a limiting sleeve 15 is fixed on the limiting belt 14; elastic belts 16 are respectively fixedly connected to opposite sides of the outer wall of the storage box 1; a hook 17 is fixed on the elastic belt 16; when the sealing cover 2 seals the storage box 1, the hook 17 is connected to the limiting sleeve 15 one by one through the stretching of the elastic belt 16.

[0025] Through the elastic stretching of the elastic band 16, when the hook 17 is connected to the limiting sleeve 15, a certain pulling force can be maintained on the sealing cover 2, ensuring the tightness and firmness of the sealing cover 2 to the storage box 1, and avoiding the sealing cover 2 from being accidentally opened due to dropping.

[0026] The outer ends of the pipe joint 5, the exhaust joint 7 and the air inlet joint 8 are all stepped structures; the two ends of the air supply hose 11 are respectively plugged into the outer ends of the pipe joint 5 and the exhaust joint 7; the air extraction hose 12 is plugged into the outer end of the air inlet joint 8. This is helpful for connecting and replacing air supply hoses 11 and air extraction hoses 12 of different specifications.

[0027] The exhaust hose 12 and the air supply hose 11 are both made of silicone tube material. The silicone tube material has stable performance and strong elasticity, which can not only ensure the tightness of the connection with each interface, but also ensure durability and not be easily damaged by external gas.
