Description

Technical Field

[0001] This utility model relates to the field of gas collection technology, specifically to a safe and environmentally friendly gas collection device. Background Technology

[0002] A negative pressure gas sampler is a gas collection device based on the principle of negative pressure. It generates negative pressure through a built-in pump, automatically drawing ambient gas into a sampling bottle or analysis system. Its core advantages lie in safety and environmental friendliness: it uses an explosion-proof casing and intrinsically safe circuitry, making it suitable for high-risk environments such as coal mines and chemical plants; it is equipped with a gas purification module to reduce the emission of harmful substances; and its low-power design reduces energy consumption.

[0003] However, traditional negative pressure gas samplers mainly rely on preset sampling volume or time to control gas flow during collection, and cannot monitor the expansion degree of the sampling container (such as a gas bag) in real time. If the continuous injection of gas causes the container to expand excessively, it may cause rupture or leakage. Therefore, a safe and environmentally friendly gas collection device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a safe and environmentally friendly gas collection device to solve the problem that traditional negative pressure gas samplers cannot monitor the expansion of the sampling container (such as a gas bag) in real time during collection.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A safe and environmentally friendly gas collection device includes a negative pressure gas sampler. An inlet pipe is provided at the input end of the negative pressure gas sampler. A gas bag is provided on one side of the negative pressure gas sampler, and an exhaust pipe is fixedly connected to the input end of the gas bag. The input end of the exhaust pipe is connected to the output end of the negative pressure gas sampler. Two horizontal bars are provided on one side of the negative pressure gas sampler, and a vertical bar is fixedly installed at the bottom of each horizontal bar. The bottom of the upper vertical bar is fixedly connected to the adjacent horizontal bar, and a long rod is fixedly installed at the bottom of the lower vertical bar. A sliding groove is provided at the bottom of the negative pressure gas sampler, and the long rod is movably installed inside the sliding groove. A limiting component for fixing the position of the long rod is provided on the negative pressure gas sampler. The side wall of each horizontal bar... Two strip plates are fixedly installed on each side. A sensor is fixedly installed on the side of each pair of horizontal strip plates that are far apart from each other. Several equally spaced circular holes are opened on the side wall of each strip plate. A compression rod assembly with telescopic function is installed inside each circular hole. Two convex grooves are opened on the front and rear sides of the negative pressure gas sampler corresponding to the height of each horizontal bar. A protrusion is movably installed inside each convex groove. An L-shaped block is fixedly installed on the side wall of each protrusion. Each L-shaped block is fixedly connected to the adjacent strip plate. Grooves are opened on the front and rear sides of the negative pressure gas sampler corresponding to the height of each horizontal bar. A guardrail assembly is installed on the negative pressure gas sampler to prevent the gas bag from falling.

[0007] Furthermore, the limiting component includes a hexagonal hole 1, and two hexagonal holes 1 are formed on the inner side wall of the slide groove. A hexagonal cylinder is fixedly installed inside each hexagonal hole 1, and a hexagonal rod is movably installed inside each hexagonal cylinder. A spring 1 is fixedly installed at the end of each hexagonal rod away from the long rod. The end of each spring 1 away from the long rod is fixedly connected to the inner bottom surface of the adjacent hexagonal cylinder. A round rod is fixedly installed at the end of each hexagonal rod away from the long rod. Each round rod passes through the adjacent hexagonal cylinder. A push rod is fixedly connected to the ends of the two hexagonal cylinders away from the long rod. Two hexagonal holes 2 are formed on the side wall of the long rod.

[0008] Furthermore, the extrusion rod assembly includes a cylinder, with a cylinder fixedly installed inside each circular hole, an extrusion rod movably installed inside each cylinder, a spring II fixedly installed at the end of each extrusion rod away from the air bag, and the end of each spring II away from the air bag fixedly connected to the inner bottom surface of the adjacent cylinder, a through hole initially provided on the inner bottom surface of each cylinder, and a cylinder fixedly installed at the end of each extrusion rod away from the air bag, with each cylinder penetrating the interior of the adjacent through hole.

[0009] Furthermore, the guardrail assembly includes a second convex groove, and the front and rear side walls of the negative pressure gas sampler are respectively provided with the second convex groove. A second protrusion is movably installed inside each second convex groove, and an L-shaped rod is fixedly installed on the side wall of each second protrusion. A U-shaped frame is fixedly installed between the two L-shaped rods.

[0010] Furthermore, the guardrail assembly also includes a magnetic block 1, with magnetic blocks 1 respectively embedded at both ends of the U-shaped frame, and two magnetic blocks 2 respectively embedded at the top of the two strip plates located above, with magnetic blocks 2 and magnetic blocks 1 attracting each other.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When the negative pressure gas sampler is activated, the air intake pipe draws air from the environment, and the sampler then injects the drawn air into the gas bag through the exhaust pipe. To prevent the gas bag from over-inflating, the horizontal and vertical bars are first pulled as far away from the negative pressure gas sampler as possible, and then the limiting component is used to fix the horizontal and vertical bars in their current positions. Then, the gas bag is placed between the two corresponding strip plates at each level, and the guardrail component is adjusted to limit the position of the gas bag. If the gas bag over-inflates, it will squeeze the squeezing rod component. When the squeezing rod component comes into contact with the adjacent sensor, it will immediately send a signal to stop sampling, preventing the gas bag from over-inflating and exploding. When gas sampling is not required, the horizontal and vertical bars can be pulled as close as possible to the negative pressure gas sampler, and then the limiting component is used to fix the horizontal and vertical bars in their current positions, making the negative pressure gas sampler easy to carry and store.

[0025] like Figures 1 to 6This invention discloses a safe and environmentally friendly gas collection device, comprising a negative pressure gas sampler 1 (the negative pressure gas sampler 1 is prior art and will not be described in detail here). An inlet pipe 2 is provided at the input end of the negative pressure gas sampler 1. A gas bag 3 is provided on one side of the negative pressure gas sampler 1. An exhaust pipe 4 is fixedly connected to the input end of the gas bag 3. The input end of the exhaust pipe 4 is connected to the output end of the negative pressure gas sampler 1. Two horizontal bars 5 are provided on one side of the negative pressure gas sampler 1. A vertical bar 6 is fixedly installed at the bottom of each horizontal bar 5. The bottom of the upper vertical bar 6 is fixedly connected to the adjacent horizontal bar 5, and a long bar 7 is fixedly installed at the bottom of the lower vertical bar 6. The bottom of the negative pressure gas sampler 1 has a sliding groove 8, and the long rod 7 is movably installed inside the sliding groove 8. The negative pressure gas sampler 1 is provided with a limiting component 9 to fix the position of the long rod 7. Two strip plates 10 are fixedly installed on the side wall of each horizontal bar 5. A sensor 11 is fixedly installed on the side of each pair of horizontal strip plates 10 that are far apart from each other. Several equally spaced circular holes 12 are opened on the side wall of each strip plate 10. A compression rod assembly 13 with telescopic function is provided inside each circular hole 12. Two convex grooves 14 are opened on the front and rear sides of the negative pressure gas sampler 1 corresponding to the height of each horizontal bar 5. A convex rod assembly 13 is movably installed inside each convex groove 14. Block 15, each protrusion 15 has an L-shaped block 16 fixedly installed on its side wall, and each L-shaped block 16 is fixedly connected to the adjacent strip plate 10. The front and rear sides of the negative pressure gas sampler 1 are provided with grooves 17 corresponding to the height of each horizontal bar 5. The negative pressure gas sampler 1 is provided with a guardrail assembly 18 to prevent the gas bag 3 from falling. It should be noted that when the negative pressure gas sampler 1 is started, the air inlet pipe 2 draws air from the environment, and the negative pressure gas sampler 1 then injects the drawn air into the interior of the gas bag 3 through the exhaust pipe 4. In order to avoid the gas bag 3 from over-inflating, the horizontal bar 5 and the vertical bar 6 are first pulled to the farthest away from the negative pressure gas sampler 1. Then, with the help of the limiting component 9, the horizontal bar 5 and the vertical bar 6 are fixed in their current positions. Then, the air bag 3 is placed between the two corresponding strip plates 10 at each level. Then, the guardrail component 18 is adjusted to limit the position of the air bag 3. If the air bag 3 inflates excessively, it will squeeze the squeezing rod component 13. When the squeezing rod component 13 comes into contact with the adjacent sensor 11, it will immediately send a signal to stop sampling to prevent the air bag 3 from exploding due to excessive expansion. When gas sampling is not required, the horizontal bar 5 and the vertical bar 6 can be pulled to the side closest to the negative pressure gas sampler 1. Then, with the help of the limiting component 9, the horizontal bar 5 and the vertical bar 6 are fixed in their current positions, making the negative pressure gas sampler 1 easy to carry and store.

[0026] The limiting component 9 includes a hexagonal hole 901. Two hexagonal holes 901 are formed on the inner sidewall of the slide groove 8. A hexagonal cylinder 902 is fixedly installed inside each hexagonal hole 901. A hexagonal rod 903 is movably installed inside each hexagonal cylinder 902. A spring 904 is fixedly installed at the end of each hexagonal rod 903 away from the long rod 7. The end of each spring 904 away from the long rod 7 is fixedly connected to the inner bottom surface of the adjacent hexagonal cylinder 902. A round rod 905 is fixedly installed at the end of each hexagonal rod 903 away from the long rod 7. Each round rod 905 penetrates the adjacent hexagonal cylinder 902. The ends of the two hexagonal cylinders 902 away from the long rod 7 together... The push rod 906 is fixedly connected to the long rod 7. Two hexagonal holes 907 are opened on the side wall. It should be noted that when the horizontal rod 5 and the vertical rod 6 are pulled, the push rod 906 is pulled away from the negative pressure gas sampler 1, so that the two hexagonal rods 903 compress the corresponding springs 904 respectively. When the horizontal rod 5 and the vertical rod 6 are pulled away from the negative pressure gas sampler 1 to the farthest, the push rod 906 is released, so that the hexagonal rods 903 are inserted into the adjacent hexagonal holes 907. When the horizontal rod 5 and the vertical rod 6 are pulled close to the negative pressure gas sampler 1, the push rod 906 is released, so that the hexagonal rods 903 are inserted into the adjacent hexagonal holes 907.

[0027] The extrusion rod assembly 13 includes a cylinder 1301. A cylinder 1301 is fixedly installed inside each circular hole 12. An extrusion rod 1302 is movably installed inside each cylinder 1301. A spring 1303 is fixedly installed at the end of each extrusion rod 1302 away from the air bag 3. The end of each spring 1303 away from the air bag 3 is fixedly connected to the bottom surface of the inner side of the adjacent cylinder 1301. A through hole 1304 is provided at the bottom surface of the inner side of each cylinder 1301. A cylinder 1305 is fixedly installed at the end of each extrusion rod 1302 away from the air bag 3. Each cylinder 1305 penetrates the interior of the adjacent through hole 1304. It should be noted that if the air bag 3 expands excessively, it will squeeze the extrusion rod 1302. The extrusion rod 1302 will then drive the cylinder 1305 connected to it to contact the adjacent sensor 11. At the same time, the extrusion rod 1302 compresses the corresponding spring 1303. When the sensor 11 senses the contact of the object, it will immediately send a signal to stop sampling.

[0028] The guardrail assembly 18 includes a second convex groove 1801. The front and rear side walls of the negative pressure gas sampler 1 are respectively provided with the second convex groove 1801. A second protrusion 1802 is movably installed inside each second convex groove 1801. An L-shaped rod 1803 is fixedly installed on the side wall of each second protrusion 1802. A U-shaped frame 1804 is fixedly installed between two L-shaped rods 1803. It should be noted that when the air bag 3 is placed between two corresponding strip plates 10 at each level, the U-shaped frame 1804 can be pulled to move above the air bag 3. The U-shaped frame 1804 drives the L-shaped rod 1803 and the second protrusion 1802 to move synchronously. The second protrusion 1802 slides inside the corresponding second protrusion 1802. The U-shaped frame 1804 is used to prevent the air bag 3 from falling.

[0029] The guardrail assembly 18 also includes a magnetic block 1805. Magnetic blocks 1805 are respectively embedded at both ends of the U-shaped frame 1804. Two magnetic blocks 1806 are respectively embedded at the top of the two strip plates 10 located above. Magnetic blocks 1806 and magnetic blocks 1805 attract each other. It should be noted that after the U-shaped frame 1804 is pulled to move above the air bag 3, each magnetic block 1805 can attract the adjacent magnetic block 1806 to position the U-shaped frame 1804.

[0030] A buzzer 19 is fixedly installed on the front wall of the negative pressure gas sampler 1. The buzzer 19 is connected to each sensor 11 via a wireless signal. It should be noted that the buzzer 19 can also issue an alarm when the sensor 11 emits a signal to remind the sampling personnel to check the gas sampling work in a timely manner.

[0031] In summary:

[0032] When the negative pressure gas sampler 1 is activated, the air inlet pipe 2 draws in air from the environment. The negative pressure gas sampler 1 then injects the drawn air into the gas bag 3 through the exhaust pipe 4. To prevent the gas bag 3 from over-inflating, the horizontal bar 5 and vertical bar 6 are first pulled as far away from the negative pressure gas sampler 1 as possible. Then, the limiting component 9 is used to fix the horizontal bar 5 and vertical bar 6 in their current positions. The gas bag 3 is then placed between the two corresponding strip plates 10 at each level. The guardrail component 18 is then adjusted to limit the position of the gas bag 3. If the gas bag 3 over-inflates, it will squeeze the squeezing rod component 13. When the squeezing rod component 13 comes into contact with the adjacent sensor 11, it will immediately send a signal to stop sampling, preventing the gas bag 3 from over-inflating and exploding. When gas sampling is not required, the horizontal bar 5 and vertical bar 6 can be pulled as close as possible to the negative pressure gas sampler 1. The limiting component 9 is then used to fix the horizontal bar 5 and vertical bar 6 in their current positions, making the negative pressure gas sampler 1 easy to carry and store.
