Description

Technical Field

[0001] This utility model belongs to the field of greenhouse gas cultivation, specifically, it relates to a static greenhouse gas incubator for soil. Background Technology

[0002] Over the past few decades, the demands for experimental equipment in scientific research have continuously evolved to adapt to new research directions and technological requirements. Traditional static incubators are mostly made of PVC (polyvinyl chloride) or PP (polypropylene). While these materials offer certain cost advantages and some resistance to chemical corrosion, they have significant shortcomings in terms of sealing, high-temperature resistance, aging resistance, and chemical stability. For example, PVC may release plasticizers during high-temperature or long-term use, while PP has relatively poor sealing properties, making it prone to gas leakage. These characteristics limit their application in high-precision experiments.

[0003] Existing static incubators made of PVC or PP materials are limited by their material and design, and cannot meet the experimental needs of accurately monitoring soil greenhouse gas emissions and studying the interaction between microplastics and soil. In view of this, this utility model is proposed. Utility Model Content

Flanges are provided on opposite sides of the tank body and the tank cover, and the opposite sides of the two flanges are tightly fitted together. A pipe body is connected to the axis above the tank cover. A balance bag inlet pipe and a gas collection pipe are respectively connected to the upper edge of the tank cover. The pipe body is located between the balance bag inlet pipe and the gas collection pipe. A micro-range pressure gauge for monitoring the internal pressure of the tank body is provided at the upper end of the pipe body. A screw cap is threaded to the upper end of the balance bag inlet pipe. A sealing structure is provided inside the gas collection pipe.

[0006] Optionally, it also includes a fastening mechanism for securing the tank body and the tank cover. The fastening mechanism includes an arc-shaped ring, with multiple "ladder" plates fixedly connected to the inner wall of the arc-shaped ring, and a flange located within the space of the "ladder" plates.

[0007] Optionally, a connecting frame is fixedly connected to one side of the outer wall at both ends of the arc plate, and a rod is rotatably connected inside the connecting frame. A threaded hole is opened through the opposite side of the rod, and a screw is threaded into the threaded hole.

[0008] Optionally, the sealing structure includes a sphere rotatably connected inside the gas collecting pipe, with rotating rods fixedly connected to both sides of the sphere passing through the gas collecting pipe, and an outlet is provided through the sphere in the vertical direction.

[0009] Optionally, one end of one of the rotating rods is fixedly connected to a connecting plate, and one end of the other rotating rod is fixedly connected to a connecting rod.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Please see Figure 1-3 As shown, this embodiment provides a static soil greenhouse gas incubator, including a tank 1 and a lid 2. Flanges 3 are provided on opposite sides of both the tank 1 and lid 2, and the two flanges 3 are tightly fitted together. A pipe 4 is connected to the central axis above the lid 2. A balance bag inlet pipe 5 and a gas collection pipe 6 are connected to the upper edge of the lid 2, respectively. The pipe 4 is located between the balance bag inlet pipe 5 and the gas collection pipe 6. A micro-range pressure gauge 7 for monitoring the internal pressure of the tank 1 is installed at the upper end of the pipe 4. A screw cap 8 is threadedly connected to the upper end of the balance bag inlet pipe 5. A sealing structure is provided inside the gas collection pipe 6. By setting the flange 3 structure and components such as the balance bag inlet pipe 5 and the gas collection pipe 6, a tight connection and seal between the tank 1 and the lid 2 are achieved, while simultaneously providing complete functions for gas collection and monitoring. This design enables the incubator to effectively simulate the soil greenhouse gas generation environment, ensuring no gas leakage during the experiment and guaranteeing the accuracy and reliability of the experimental data. Furthermore, the micro-range barometer 7 allows for real-time monitoring of pressure changes within the tank, providing a basis for the standardization of experimental data. In this application, the tank body 1, tank cover 2, balance bag inlet pipe 5, and gas collection pipe 6 are all made of glass.

[0018] A static greenhouse gas incubator for soil includes a fastening mechanism for securing the tank body 1 and the tank lid 2. The fastening mechanism includes an arc-shaped ring, with multiple trapezoidal plates fixedly connected to the inner wall of the arc-shaped ring, and a flange 3 located within the space of the trapezoidal plates. The tank body 1 and the tank lid 2 fit tightly together during the experiment, preventing gas leakage, and can be flexibly adjusted according to different experimental needs and the size of the tank body 1. The optimized fastening mechanism significantly improves the sealing performance and operational convenience of the incubator, enhancing its overall stability and reliability.

[0019] In this embodiment, a connecting frame 10 is fixedly connected to one side of the outer wall at both ends of the arc-shaped plate. A rod 11 is rotatably connected inside the connecting frame 10. A threaded hole is opened through the opposite side of the rod 11, and a screw 12 is threaded into the threaded hole. The setting of the connecting frame 10 and the screw 12 further optimizes the function of the fastening mechanism. This design makes the adjustment of the fastening mechanism more stable. The operator can adjust the fastening force of the arc-shaped ring by rotating the screw 12, thereby controlling the sealing degree of the tank body 1 and the tank cover 2.

[0020] In this embodiment, the sealing structure includes a sphere 13 rotatably connected inside the gas collection pipe 6. Rotating rods 14, passing through the gas collection pipe 6, are fixedly connected to both sides of the sphere 13. An outlet is formed through the sphere 13 in the vertical direction. The design of the sealing structure, especially the combination of the sphere 13 and the rotating rods 14, provides an efficient and controllable sealing method for the gas collection pipe 6. By rotating the sphere 13, the entry and exit of gas can be flexibly controlled, enabling precise gas collection. This design not only effectively prevents gas leakage and ensures the purity and accuracy of the collected gas, but also achieves complete sealing when the sphere 13 is closed when not in use, maintaining a stable gas environment inside the tank.

[0021] In this embodiment, one end of one rotating rod 14 is fixedly connected to a connecting plate, and one end of the other rotating rod 14 is fixedly connected to a connecting rod. The design of the connecting plate at one end of the rotating rod 14 provides the operator with a more convenient operating method. The connecting plate allows the operator to rotate the ball 13 more easily, thereby achieving the sealing and opening operations of the gas collection pipe 6.

[0022] In this embodiment, the micro-range barometer 7 has an air inlet pipe 15 at its lower end, and a threaded cylinder 16 is connected to the upper part of the tube body 4. The outer circumference of the lower end of the air inlet pipe 15 has an external thread that mates with the inner thread of the threaded cylinder 16. This threaded connection between the micro-range barometer 7 and the tube body 4 ensures the airtightness and stability of the barometer monitoring system. Through the cooperation of the air inlet pipe 15 and the threaded cylinder 16, the barometer can be securely installed on the tube body 4, preventing loosening or detachment due to vibration or external force. Silicone rings are provided on opposite sides of the flange 3, and the two opposite silicone rings are staggered; specifically, the diameter of one silicone ring is larger than the diameter of the other.
