Description

Technical Field

[0001] This utility model relates to the technical field of soil gas observation devices, specifically a buried soil gas collector. Background Technology

[0002] Traditional soil gas samplers require pre-drilling holes using a steel rod or electric drill, which is time-consuming and labor-intensive. Drilling holes with a steel rod requires manual insertion of a sledgehammer into the soil surface. When large-area soil gas concentration surveys are involved, this will inevitably lead to a huge manpower investment. Drilling holes involves the issue of field power sources. Even with high-capacity lithium batteries, there may be technical problems in drilling holes in solid soil layers or soil layers with high water content.

[0003] Traditional soil gas samplers require the disruption of the surface soil, which cannot guarantee the compaction of the surface soil, causing the dissipation of gases within the soil and making it impossible to conduct long-term observations of changes in soil gas concentration. Based on the current status of existing soil gas samplers, in order to achieve soil gas sampling and long-term observation of changes in soil gas concentration, those skilled in the art have provided a buried soil gas sampler to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an embedded soil gas collector to solve the problems mentioned in the background art.

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

[0006] An embedded soil gas collector includes a main pipe with a pipe connector threaded to its outer surface. A connecting pipe is installed at the top of the pipe connector, and a flexible hose connector is installed at the top of the connecting pipe. A secondary pipe is provided inside the main pipe, and an elastic flexible hose is fixedly connected to the top of the flexible hose connector. A first annular arrangement of air guide holes is opened on the outer surface of the main pipe, and a second annular arrangement of air guide holes is opened on the outer surface of the secondary pipe. Filter cotton is provided between the main pipe and the secondary pipe.

[0007] As a further embodiment of this utility model: the outer surface of the main pipe is threaded with a main pipe cap, and the outer surface of the secondary pipe is threaded with a secondary pipe cap.

[0008] As a further embodiment of this utility model: a valve is installed on the outer surface of the elastic hose, and a connecting seat is fixedly connected to the outer surface of the elastic hose.

[0009] As a further improvement of this utility model: a storage box is installed on the upper surface of the connecting seat, and a flexible tube collection port is opened on the upper surface of the storage box.

[0010] As a further improvement of this utility model: the end of the elastic hose away from the main pipe is fixedly connected to an air outlet pipe, and the filter cotton is made of igneous rock material.

[0011] As a further improvement of this utility model: both the main pipe and the secondary pipe are PVC-U pipes, and the diameter of each of the first air guide holes is smaller than the diameter of the second air guide hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This buried soil gas sampler features a detachable design that makes it easy to operate and carry. It is suitable for gas collection in various soil environments and boasts excellent sealing performance. The design of the pipe connector, connecting pipe, and hose connector ensures the sampler's airtightness and prevents gas from escaping from the soil. The sampler can be used for soil gas collection at different depths and is applicable to multiple fields such as soil science research, environmental monitoring, and agricultural management. The design, with both the sampler and the storage box located in the soil, effectively protects the device from loss and damage. Attached Figure Description

[0022] Please see Figures 1-5 In this embodiment of the invention, an embedded soil gas sampler includes a main pipe 1, a pipe connector 2 threadedly connected to the outer surface of the main pipe 1, a connecting pipe 3 installed at the top of the pipe connector 2, a flexible hose connector 4 installed at the top of the connecting pipe 3, a secondary pipe 5 inside the main pipe 1, and an elastic flexible hose 6 fixedly connected to the top of the flexible hose connector 4. The outer surface of the main pipe 1 has annularly arranged first air guide holes 12, and the outer surface of the secondary pipe 5 has annularly arranged second air guide holes 16. A filter cotton 13 is provided between the main pipe 1 and the secondary pipe 5. This allows for long-term observation of changes in soil gas concentration, thus solving the problem that traditional soil gas samplers require damage to the surface soil, cannot guarantee the compaction of the surface soil, and cause the dissipation of soil gas, making long-term observation of changes in soil gas concentration impossible.

[0023] The outer surface of the main pipe 1 is threaded with a main pipe cap 15, the outer surface of the secondary pipe 5 is threaded with a secondary pipe cap 14, the outer surface of the flexible hose 6 is equipped with a valve 10, and the outer surface of the flexible hose 6 is fixedly connected with a connecting seat 7, which can block soil particles and prevent soil from entering the interior of the main pipe 1 and the secondary pipe 5.

[0024] A storage box 8 is installed on the upper surface of the connecting seat 7. A flexible hose collection port 9 is opened on the upper surface of the storage box 8. The end of the flexible hose 6 away from the main pipe 1 is fixedly connected to the air outlet pipe 11. The filter cotton 13 is made of igneous rock material. The main pipe 1 and the secondary pipe 5 are both PVC-U pipes. The diameter of each first air guide hole 12 is smaller than the diameter of the second air guide hole 16, which makes the equipment have the characteristics of strong corrosion resistance, easy bonding and low price.

[0025] The working principle of this utility model is as follows: When in use, the assembled equipment and storage box 8 are buried in the soil at the sampling point, and the gas outlet pipe 11 is connected to the pump-suction gas detector. First, the soil gas enters the interior of the main pipe 1 through the first gas guide hole 12. Then, the filtered gas enters the secondary pipe 5 through the second gas guide hole 16, and enters the pump-suction gas detector through the elastic hose 6 connected at the top. Finally, people can control the flow of gas through the valve 10, so that people can observe the changes in the gas concentration in the soil multiple times or continuously.
