Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to a sampling device for greenhouse gas monitoring. Background Art

[0002] Greenhouse gases refer to some gases in the atmosphere that can absorb long-wave radiation reflected by the ground and re-emit radiation, such as water vapor, carbon dioxide, and most refrigerants. The existence of greenhouse gases forms a greenhouse structure on the earth's surface to intercept solar radiation, making the earth's surface warmer and causing more serious impacts on environmental health.

In order to ensure multiple groups of sampling The cylinder 43 can collect gas at the same time, and by fixedly connecting multiple groups of hydraulic rods 46 to the connecting plate 5, when the connecting plate 5 moves backward, it can drive the hydraulic rods 46 to collect gas at the same time, which is convenient and quick. A slide groove 7 is opened on the lower surface of the mounting plate 3, and a motor 8 is fixedly connected to the inner surface of the slide groove 7. A first threaded rod 9 is fixedly connected to the output shaft of the motor 8. The first threaded rod 9 passes through the movable block 6 and is threadedly connected to the movable block 6. The movable block 6 is slidably connected to the inner surface of the slide groove 7. In order to ensure that the movable block 6 can drive the connecting plate 5 to move, the slide groove 7 is used to limit the movable block 6 so that the movable block 6 can only move in the slide groove 7. The first threaded rod 9 is controlled by the first threaded rod 9 and the motor 8 to achieve the control effect on the connecting plate 5.

[0026] In this embodiment, the sampling box 41, the piston 45, the connecting plate 5 and the first threaded rod 9 are provided to control the forward and backward movement of the connecting plate 5, so that multiple groups of sampling tubes 43 can collect the gas to be monitored at the same time.

[0027] Embodiment 2

[0028] See also Figure 1-Figure 4On the basis of the first embodiment, the utility model provides a technical solution: preferably, a dustproof mechanism 10 is provided on the upper surface of the sampling box 41, and the dustproof mechanism 10 includes a vertical frame 101, a slider 102 is slidably connected in the vertical frame 101, and a dustproof plate 103 is fixedly connected to the front surface of the slider 102. The inner surface of the vertical frame 101 is rotatably connected to the second threaded rod 11, and the second threaded rod 11 passes through the slider 102 and is threadedly connected to the slider 102. In order to ensure that when the second threaded rod 11 rotates, the slider 102 will not follow the second threaded rod 11. The slider 102 is rotated and limited by the fixed vertical frame 101 to ensure the stable movement of the slider 102, which can drive the dustproof plate 103 to move downward to cover the air inlet of the sampling tube 43.

When the second threaded rod 11 drives the slider 102 to move downward, the slider 102 drives the dustproof plate 103 to move downward, covering the air inlet of the sampling tube 43 to prevent impurities from entering the sampling tube 43 as much as possible.
