Problems solved by technology

The length of the drill pipe assembly in this device is fixed, and the sampling depth is limited; and the drill pipe assembly cannot be completely disassembled, and the inner cavity of the drill pipe is small, which is not conducive to cleaning
The sample collector is closed when the device enters the soil, and the soil gas is collected during the proposed process, which makes it difficult to collect soil gas when the sampling depth is shallow
The detection and collection of the device adopts a series structure, so that the soil gas detected on site and the soil gas detected indoors do not have simultaneity

Embodiment 1

[0026] Such as figure 1 Shown, the present invention provides a kind of novel soil gas collection and detection device here, comprises drill bit assembly, sample collector, gas fast detector, air pump 18, and one end of sample collector is connected with drill bit assembly, and the other end is connected with air pump 18 Connection, the gas fast detector is connected with the sample collector.

[0027] The drill bit assembly is composed of drill bit 1, air intake section 2, extension section 3 and hammering section 4 which are sequentially connected by connectors. It can be assembled quickly and effectively during sampling, speeding up the sampling speed, and cleaning each part after sampling. The air intake section 2 and the extension section 3 are hollow cylinders, and the connecting part between the hammering section 4 and the extension section 3 is a hollow cylinder, which is convenient for cleaning.

[0028] The drill bit 1 is conical, and the drill bit assembly can be q...

Embodiment 2

[0045] Such as figure 2 As shown, this embodiment further optimizes the design on the basis of the above embodiments, specifically: the power supply equipment is set to be powered by solar energy, so that there is no need to recharge the battery repeatedly, and the soil gas can be collected continuously.

[0046] The solar battery 25 is connected to the air pump 18 through the wire 20, the solar battery 25 is electrically connected to the solar panel 26, and the solar energy is used for power supply, which is not only environmentally friendly, but also takes a short sampling time, and can also collect samples for a long time.

[0047] In the present invention, the length of the drill assembly can be changed, so that the sampling depth is not limited, and the sampling site is wide; and when the drill assembly is inserted or proposed, the soil gas will enter the drill assembly, so that the sample collection speed is fast; the completeness of the drill assembly It can be disasse...
