Technical Field

[0001] This utility model relates to the field of gas detection and collection technology, specifically to a gas detection and collection device for environmental monitoring. Background Technology

[0002] In the air, when the concentration of pollutants reaches or exceeds harmful levels, it disrupts ecosystems and hinders normal human survival and development, causing harm to humans and other organisms. This is the most direct and serious issue, primarily stemming from carbon monoxide and hydrogen sulfide emitted from factories, automobiles, and power plants. Every day, people contract respiratory or visual diseases from exposure to this polluted air. With increasing national emphasis on environmental issues, more and more companies are producing environmental instruments such as air samplers. Thanks to the continuous research and development by these entrepreneurs and their research teams, today's air samplers are more accurate and feature-rich.

[0003] Existing gas sampling equipment typically uses pistons to collect gases from contaminated areas. However, when traditional gas collection devices are filled with gas, a large amount of air will rush out when the filling device is pulled out after filling, which affects the efficiency of environmental monitoring.

[0004] Therefore, we propose a gas detection and collection device for environmental monitoring. Utility Model Content

[0005] The purpose of this invention is to provide a gas detection and collection device for environmental monitoring, so as to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This environmental monitoring gas detection and collection device, by setting up an air cylinder, moves the gas storage tank to the air collection position via a movable base. Then, the drive motor is started to rotate the air cylinder. When the air cylinder draws in air, the first one-way valve opens and the second one-way valve closes, allowing air to be delivered into the air cylinder through the inlet pipe. Subsequently, the second one-way valve opens and the first one-way valve closes, sending air into the gas storage tank through the delivery pipe. As the air inside the storage tank increases, the piston plate moves downward. When removing air from the storage tank, the shut-off valve of the discharge pipe opens, and the spring lifts the piston plate. The air inside the storage tank is then discharged through the discharge pipe under the pressure of the piston plate. No gas overflows during sampling and venting, thus not affecting the efficiency of environmental monitoring.

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.

[0022] Please see Figures 1 to 4This utility model provides a gas detection and collection device for environmental monitoring, including a movable base 1, a gas storage tank 2 fixedly installed on the top of the movable base 1, a drive motor 3 fixedly installed on the top of the gas storage tank 2, an inflation cylinder 4 fixedly installed on the top of the gas storage tank 2, an exhaust pipe 10 located on one side of the drive motor 3 fixedly installed on the top of the gas storage tank 2, a guide slide rod 12 fixedly installed inside the gas storage tank 2, a piston plate 13 slidably connected inside the gas storage tank 2, the middle part of the piston plate 13 slidably connected to the guide slide rod 12, a lifting spring 14 located below the piston plate 13 sleeved on the outside of the guide slide rod 12, the output end of the drive motor 3 being drivenly connected to the movable end of the inflation cylinder 4, an air inlet pipe 5 fixedly installed at one end of the inflation cylinder 4, an air delivery pipe 8 located in front of the air inlet pipe 5 fixedly installed at one end of the inflation cylinder 4, a first one-way valve 7 provided at the connection between the air inlet pipe 5 and the inflation cylinder 4, and an air delivery pipe 8 fixedly installed at the other end of the air inlet pipe 5. A second one-way valve 9 is installed at the connection between the gas collection hood 6, the air supply pipe 8, and the air cylinder 4. The other end of the air supply pipe 8 is fixedly installed on the top of the air storage tank 2. After the air storage tank 2 is moved to the position for collecting air by the moving base 1, the drive motor 3 is started to drive the air cylinder 4 to operate. When the air cylinder 4 draws in air, the first one-way valve 7 opens and the second one-way valve 9 closes. Air is delivered to the inside of the air cylinder 4 through the air inlet pipe 5. Then the second one-way valve 9 opens and the first one-way valve 7 closes. Air is sent into the inside of the air storage tank 2 through the air supply pipe 8. As the air inside the air storage tank 2 in the cabinet increases, the piston plate 13 moves down. When the air inside the air storage tank 2 is taken out, the shut-off valve 11 of the discharge pipe 10 is opened, and the lifting spring 14 lifts the piston plate 13. The air inside the air storage tank 2 is discharged through the discharge pipe 10 under the compression of the piston plate 13. There is no gas overflow during sampling and exhaust, which will not affect the working efficiency of environmental monitoring.

[0023] The top of the gas tank 2 is rotatably connected to a crankshaft 16 located behind the drive motor 3 via a bracket. The output end of the drive motor 3 is fixedly installed at one end of the crankshaft 16. A connecting rod 19 is rotatably connected to the middle of the crankshaft 16. A compression piston 20 is fixedly installed at the other end of the connecting rod 19. The compression piston 20 is slidably connected to the inside of the air cylinder 4.

[0024] A fixing rod 17 is fixedly installed on the top of the gas storage tank 2 by a bracket. A sleeve 18 is fixedly installed on one end of the air cylinder 4 facing the crankshaft 16. A connecting rod 19 is slidably connected to the middle of the sleeve 18. One end of the sleeve 18 is fixedly installed to the air cylinder 4, and the other end of the sleeve 18 is fixedly installed to the end of the fixing rod 17. By setting up the air cylinder 4, when gas sampling is performed, the drive motor 3 drives the crankshaft 16 to rotate, and then the crankshaft 16 drives the connecting rod 19 to move back and forth, so that the connecting rod 19 pulls the extrusion piston 20 to move back and forth inside the air cylinder 4, thereby continuously pumping and sucking in air to fill the gas storage tank 2.

[0025] The top of the lifting spring 14 is pressed against the bottom of the piston plate 13, and the bottom of the lifting spring 14 is pressed against the bottom of the interior of the gas tank 2.

[0026] The bottom of the gas storage tank 2 is provided with a vent hole 15, the outer peripheral surface of the piston plate 13 is in a sealed sliding connection with the inner wall of the gas storage tank 2, and the guide slide rod 12 is in a sealed sliding connection with the piston plate 13.

[0027] The mobile base 1 has a battery inside and multiple casters on its outer periphery.

[0028] The length of the air inlet pipe 5 is greater than five meters. The air inlet pipe 5 is a flexible hose. The top of the air storage tank 2 is equipped with a pipe rack for winding the air inlet pipe 5. A shut-off valve 11 is installed in the middle of the discharge pipe 10.

[0029] Working principle:

[0030] After moving the air tank 2 to the air collection position by moving the base 1, start the drive motor 3 to drive the air cylinder 4 to rotate. The drive motor 3 drives the crankshaft 16 to rotate, which in turn drives the connecting rod 19 to move back and forth. This causes the connecting rod 19 to pull the compression piston 20 to move back and forth inside the air cylinder 4, thus continuously sucking in and sucking in air. When the air cylinder 4 sucks in air, the first one-way valve 7 opens and the second one-way valve 9 closes. Air is delivered into the air cylinder 4 through the air inlet pipe 5. Then, the second one-way valve 9 opens and the first one-way valve 7 closes, and air is sent into the air tank 2 through the air delivery pipe 8. As the air inside the air tank 2 increases, the piston plate 13 moves down. When the air inside the air tank 2 is taken out, the shut-off valve 11 of the discharge pipe 10 is opened, and the spring 14 lifts the piston plate 13. The air inside the air tank 2 is squeezed by the piston plate 13 and discharged through the discharge pipe 10. No gas overflows during sampling and exhaust.
