Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically to a root gas collection and monitoring device for enhancing carbon sequestration in urban landscaping. Background Technology

[0002] Landscape greening involves planting trees, flowers, and other plants to improve the ecological environment. Greening generates carbon sinks, which refer to the absorption and storage of carbon dioxide by plants. To improve the carbon sink effect, gases are collected and monitored at the plant roots. This device can accurately collect and analyze the gas composition and dynamic changes in the plant rhizosphere environment, thereby helping researchers provide data for carbon sink research.

[0003] The current monitoring device still has some shortcomings, such as soil clogging the air inlet, which affects the flow of gas.

[0004] To overcome the low detection efficiency, a Chinese patent (publication number: CN220063543U) discloses a root respiration monitoring device, which includes a sampling probe, a gas guiding component, and a gas injection component. The outer end of the sampling probe is threaded with an outer cylinder, and a cone is fixedly connected to the bottom end of the outer cylinder to protect the gas guiding component connected to the inside of the sampling probe. The gas guiding component includes a port, an inner core rod, a cone, a guide rod, a compression spring, and an end cap. The end cap is connected inside the port, and a guide rod is installed on the right end of the end cap. A cone is slidably connected to the right side of the guide rod, and an inner core rod is rotatably connected to the upper end of the cone. The outer end of the sampling probe has multiple ports, each connected to an end cap with a matching structure and size for barrier sealing. This prevents soil from being squeezed into the ports and causing blockage when the entire sampling probe is inserted into the soil for monitoring, thus preventing gas from the soil from entering the sampling probe and affecting the monitoring effect of root respiration of bamboo rhizomes.

[0005] However, the monitoring devices currently in use still have certain shortcomings. The aforementioned document describes how the device is inserted into the soil to collect airflow and monitor the gases at the plant roots. However, when inserted into soft soil, the device is prone to tilting or slowly seeping downwards, affecting its stability. Therefore, improvements to the existing structure are needed. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a root gas collection and monitoring device for enhancing carbon sequestration in urban landscaping, comprising a sampling device, a filter screen connected to the side of the sampling device, a ventilation pipe connected through the inside of the sampling device, and a monitor connected to the end of the ventilation pipe.

[0008] The sampling device has an internal cavity, and the vent pipe and filter screen are both located inside the cavity. A rotating groove is provided on the right side of the sampling device, and a rotating ring is rotatably connected inside the rotating groove. A ratchet ring is fixed to the side of the rotating ring. A rotating mechanism for raising the support surface of the monitoring device is provided inside the rotating groove.

[0009] Furthermore, the rotating mechanism includes an extrusion block fixed to the top of the rotating ring, a rotating block rotatably connected to the side of the rotating groove near the extrusion block, and a torsion spring connected between the rotating block and the rotating groove. Both the extrusion block and the rotating block are arc-shaped blocks, and three sets of each type of rotating block and extrusion block are provided.

[0010] Furthermore, a rotating groove is provided through the side of the rotating groove, and a positioning block is rotatably connected inside the rotating groove by a torsion spring. The positioning block protrudes inside the rotating groove and is in close contact with the side of the ratchet ring.

[0011] Furthermore, the sampling device is also provided with a disassembly and assembly mechanism for easy cleaning. The disassembly and assembly mechanism includes a fixing block fixed to the side of the filter screen, and an elastic block is connected to the side of the fixing block.

[0012] Furthermore, the side of the filter screen is fixed with protruding posts, the fixing block and the guide groove are slidably connected, and the fixing block and the guide groove are provided with four sets.

[0013] Furthermore, the positioning groove is formed on the side of the guide groove, and the elastic block is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This root gas collection and monitoring device for enhancing carbon sequestration in urban landscaping features a rotatable squeezing block that drives a ratchet ring to rotate in order to ensure the stability of the sampling device when inserted into the soil.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1, such as Figures 1-5 The present invention provides the following technical solution to address the potential instability of the monitoring device after it is inserted into soft soil: A rotating mechanism is disclosed. The device includes a sampling device 1, a filter screen 2 connected to its side, and a vent pipe 3 connected through the inside of the sampling device 1. A monitor 4 is connected to the end of the vent pipe 3. The sampling device 1 has an internal cavity, and both the vent pipe 3 and the filter screen 2 are located inside the cavity. A rotating groove 101 is provided on the right side of the sampling device 1. A rotating ring 102 is rotatably connected inside the rotating groove 101. A ratchet ring 103 is fixed to the side of the rotating ring 102. A rotating mechanism for raising the support surface of the monitoring device is provided inside the rotating groove 101. The rotating mechanism includes a mechanism fixed to the top of the rotating ring 102. The extrusion block 105 has a rotating groove 101 near the side of the extrusion block 105, and a rotating block 104 is rotatably connected to it. A torsion spring connects the rotating block 104 and the rotating groove 101. Both the extrusion block 105 and the rotating block 104 are arc-shaped blocks. Three sets of rotating blocks 104 and extrusion blocks 105 are provided. A rotating groove 107 is opened through the side of the rotating groove 101. A positioning rotating block 106 is rotatably connected inside the rotating groove 107 through a torsion spring. The positioning rotating block 106 protrudes inside the rotating groove 107 and is in close contact with the side of the ratchet ring 103.

[0022] When using the monitoring device, the sampling device 1 is inserted into the soil. Gas in the soil enters the monitor 4 through the cavity inside the sampling device 1 and the ventilation pipe 3 for collection and detection. During the process, the filter screen 2 can block and filter the soil. Since the sampling device 1 needs to be inserted into the soil, in order to ensure the stability of the sampling device 1 when inserted into the soil, the squeezing block 105 can be rotated. When the squeezing block 105 rotates, it can drive the rotating ring 102 to rotate. When the rotating ring 102 rotates, it can rotate inside the rotating groove 101. When rotated, the ratchet ring 103 can be rotated. When the ratchet ring 103 rotates, the inclined surface of the teeth can press against the side of the positioning block 106. When the positioning block 106 is pressed, it can rotate inside the rotating groove 107. When the positioning block 106 rotates, it can tighten the torsion spring. At the same time, the pressing block 105 rotates and the inclined arc surface can press against the wall of the rotating block 104. When the rotating block 104 is pressed, it can rotate inside the rotating groove 101. When the rotating block 104 rotates, it can tighten the torsion spring. And the rotating block 104 rotates... The sampling device 1 can be rotated outwards. When the plane of the extrusion block 105 rotates to the side of the rotating block 104, the rotating block 104 will rotate to its maximum value. When the extrusion block 105 stops rotating, the rotating ring 102 and the ratchet ring 103 will also stop rotating. When the ratchet ring 103 is not rotating, the positioning rotating block 106 will reset under the action of the torsion spring. When the positioning rotating block 106 resets, it can rotate to the meshing plane of the ratchet ring 103 for positioning. When the ratchet ring 103 is positioned, it can drive the rotating ring 102 and the extrusion block 105 to be positioned. After the extrusion block 105 is positioned, it can... To prevent the rotating block 104 from resetting under the action of the torsion spring, the rotating block 104 is positioned. After the rotating block 104 is positioned, the area of ​​the sampling device 1 is increased. When the sampling device 1 with the rotating block 104 is inserted into the ground surface, the rotating block 104 can support the sampling device 1 and prevent the sampling device 1 from going deeper into the soil. In soft soil, the stability of the sampling device 1 can be guaranteed. At the same time, when the rotating block 104 is in contact with the ground, the vertical insertion effect of the sampling device 1 can also be guaranteed, which indirectly improves the monitoring accuracy of the monitoring device.

[0023] Example 2, as follows Figure 1 , Figure 2 , Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem of inconvenient cleaning of the filter screen 2 in the monitoring device: a disassembly and assembly mechanism is disclosed: a disassembly and assembly mechanism for easy cleaning is also provided on the side of the sampling device 1. The disassembly and assembly mechanism includes a fixing block 201 fixed to the side of the filter screen 2, an elastic block 202 connected to the side of the fixing block 201, a protruding post fixed to the side of the filter screen 2, the fixing block 201 and the guide groove 203 being slidably connected, and four sets of fixing blocks 201 and guide grooves 203 being provided. A positioning groove 204 is opened on the side of the guide groove 203, and the elastic block 202 is made of rubber.

[0024] When the monitoring device is removed from the soil, soil tends to accumulate on the side of the filter screen 2, affecting its future use. Therefore, after removing the device, pliers can be used to grip the protrusion on the side of the filter screen 2 and pull it outward. When the protrusion is pulled, the filter screen 2 can be moved. When the filter screen 2 moves, it can move the four fixed blocks 201. When the fixed blocks 201 move, they can move the elastic blocks 202. When the fixed blocks 201 move, they can slide inside the guide groove 203. When the elastic blocks 202 move, they can squeeze the inner wall of the positioning groove 204. When the elastic blocks 202 are squeezed, they can deform through their own rubber material. After the elastic blocks 202 deform, they can be squeezed out of the positioning groove 204. At this time, the fixed blocks 201 can slide outward inside the guide groove 203. When the filter screen 2 slides out of the cavity of the sampling device 1, it can be disassembled. After the filter screen 2 is disassembled, it can be cleaned, which improves the convenience of cleaning the filter screen 2.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
