Description

Technical Field

[0001] The present invention relates to the technical field of coastal wetland soil monitoring, and in particular to a soil respiration gas collection device suitable for coastal wetlands. Background Art

[0002] Coastal wetlands play an important role in global climate change. In-depth research on the respiration of coastal wetland soil will help to evaluate and further explore the carbon sequestration function of coastal wetlands.

[0003] Currently, when collecting soil respirable gases in coastal wetlands, a bottomless box is usually placed on the soil surface to form an enclosed space. Gas samples are then collected from the box at regular intervals and the collected gases are then tested using sensors or equipment. Although this method can complete the collection and detection of soil respirable gases, it still has the following drawbacks during use:

[0004] Since it is used in coastal wetland areas, the box is easily affected by the impact of waves and may be displaced or tilted, which not only affects the stable gas collection and detection work, but also reduces the service life of the box and other structures. For this reason, we propose a soil respiration gas collection device suitable for coastal wetlands. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see the attached Figure 1 -Attached Figure 2 , a soil respiration gas collection device suitable for coastal wetlands, comprising:

[0034] The collecting cylinder 1 is hollow at the bottom, and a one-way air outlet pipe 2 is inserted on it. The one-way air outlet pipe 2 is a pipe with a one-way valve inside. One end of the one-way air outlet pipe 2 is connected to the gas collecting container 3. A micro pump can be set in the gas collecting container 3. The micro pump is used to extract the soil respiration gas in the collecting cylinder 1 into the gas collecting container 3. The gas collecting container 3 has an exhaust port, and a valve body (such as a solenoid valve) is provided in the exhaust port. The gas collecting container 3 is provided with an intelligent sensor 4 for detecting soil respiration gas. The intelligent sensor 4 includes a carbon dioxide sensor and a gas temperature and humidity sensor. Of course, the intelligent sensor 4 is not limited to these two types. It is used to detect and analyze the collected soil respiration gas, which is helpful for in-depth research on the respiration and carbon fixation capacity of coastal wetland soils.

[0035] The supporting base 5 is sleeved on the outer wall of the collecting tube 1. The bottom of the supporting base 5 is provided with a plurality of vertical inserts 6 for inserting into the soil of the coastal wetland. Specifically, during installation, the user can use the power of the foot to insert the outer wall portion of the collecting tube 1 below the supporting base 5 into the wetland soil until the ground of the supporting base 5 contacts the surface of the wetland soil. The vertical inserts 6 improve the stability of the collecting tube 1 during use.

[0036] The protection mechanism 7 includes: a plurality of groups of V-shaped guide plates 71, each of which is arranged in a circular array outside the circumference of the collection tube 1 and above the supporting base 5. When the collection tube 1 is impacted by waves, the V-shaped guide plates 71 can guide the impact force of the waves to both sides and discharge it, thereby reducing the impact of the waves on the collection tube 1 and preventing the collection tube 1 from moving out of its position;

[0037] One side of the guide plate 71 is connected to the outer wall of the collecting tube 1 through several groups of elastic buffers 8. The elastic buffers 8 are, for example, elastic buffer rods or elastic damping buffers. The elastic buffers 8 can provide buffering when the guide plate 71 is impacted by waves, thereby further reducing the impact of the impact force on the collecting tube 1.

[0038] A connecting rope 20 is provided on the outer wall of the supporting base 5. One end of the connecting rope 20 can be connected to an external insertion cone. The cone is inserted into a suitable position or tied to a suitable position by the connecting rope 20. This ensures that when the collecting tube 1 is impacted by waves and moves out of its position, it will not be carried into the sea by the waves, causing the device to be lost.

[0039] The soil respiration gas collection device also includes: a shell 19 arranged on the collection tube 1, a controller, a wireless communicator and a battery arranged in the shell 19. The controller is used to control the electrical components in the device, such as the smart sensor 4, etc. The wireless communicator is used to remotely send the data detected by the smart sensor 4 to an external monitoring terminal to realize wireless signal communication and improve the comfort of use. The battery supplies power to the electrical components in the device to ensure its stable use outdoors.

[0040] Example 2

[0041] Please see the attached Figure 2 -Attached Figure 3 On the basis of embodiment 1, the protection mechanism 7 of this embodiment further includes:

[0042] A V-shaped inner movable plate 73 is inserted into the top of the guide plate 71. The inner movable plate 73 is connected to the inner wall of the guide plate 71 via a spring (not shown). Second through-holes 74 are evenly formed on the inner movable plate 73. First through-holes 72 are evenly formed on the side of the guide plate 71 away from the collecting cylinder 1. When the guide plate 71 is not moving toward the collecting cylinder 1, the second through-holes 74 and the first through-holes 72 do not correspond to each other, so that external water cannot enter the guide plate 71, and at the same time, external particles (soil) are not likely to clog the first through-holes 72.

[0043] The wedge block 75 is a right-angled trapezoid, located above the guide plate 71 and connected to the inner movable plate 73. The inclined surface of the wedge block 75 slides against a push rod 77, which is provided on the outer wall of the collection barrel 1. The end of the push rod 77 is embedded with a ball and slides against the inclined surface of the wedge block 75. When the guide plate 71 moves toward the collection barrel 1, the push rod 77 drives the inner movable plate 73 to move upward relative to the guide plate 71, so that the through hole 1 72 and the through hole 2 74 correspond to each other.

[0044] Under the impact of waves, the guide plate 71 will move toward the collecting tube 1 to squeeze the elastic buffer 8, and then the push rod 77 will push the wedge block 75, and the wedge block 75 will drive the inner movable plate 73 to move upward relative to the guide plate 71, so that the through hole 1 72 and the through hole 2 74 correspond to each other, so that the waves impacting the guide plate 71 can enter the guide plate 71 through the through hole 1 72 and the through hole 2 74, and the impact force of the waves is further dispersed in this way. Subsequently, the guide plate 71 is reset under the action of the elastic buffer 8, and the inner movable plate 73 is reset under the action of the spring.

[0045] Example 3

[0046] Please see the attached Figure 2 and attached Figure 4 -Attached Figure 5 On the basis of Example 2, a water guide 76 is obliquely provided below each of the second horizontal through holes 74 in this embodiment. One end of the water guide 76 is connected to the side of the inner movable plate 73 facing the collecting cylinder 1, and the other end forms a drainage channel with the inner wall of the guide plate 71. The end of the water guide 76 connected to the inner movable plate 73 is higher than the other end. Through the arrangement of the water guide 76, water entering the inner cavity of the guide plate 71 from the second through hole 74 is guided by the water guide 76 into the drainage channel. When the water enters, it is farther away from the second through hole 74 when it is discharged downward, thereby reducing the water from being discharged from the second through hole 74 below when it flows downward in the guide plate 71.

[0047] The inner cavity of the supporting base 5 is provided with an annular bottom plate, the top of the annular bottom plate is provided with a sponge ring 9, and the inner wall of the supporting base 5 is provided with an annular liquid separation member 10. The annular liquid separation member 10 is a conventional structure in the field, and is an annular structure device for distributing or collecting fluids. It is usually annular and distributes the incoming water evenly to the sponge ring 9 along the circumferential direction. The water outlet end of the annular liquid separation member 10 contacts the sponge ring 9, and the water inlet end of the annular liquid separation member 10 is connected to the guide plate 71 through a pipeline.

[0048] The water entering the guide plate 71 can enter the annular liquid separation component 10, and then be discharged from the annular liquid separation component 10 and absorbed by the sponge ring 9. After absorption, the sponge ring 9 increases the weight of the supporting base 5, and since the supporting base 5 is located at the lower end of the collecting tube 1, the center of gravity of the collecting tube 1 is lowered, thereby enhancing its stability in resisting the impact of waves.

[0049] Example 4

[0050] Please see the attached Figure 4 On the basis of Example 3, a movable plate 11 is inserted at the top of the vertical insert 6 of this embodiment, and one end of the movable plate 11 extends into the bearing base 5 and is connected to the annular bottom plate. The annular bottom plate is slidably arranged in the bearing base 5 and can move up and down in the bearing base 5. An elastic member (such as a spring) is provided between the annular bottom plate and the inner wall of the bearing base 5. Several groups of horizontal inserts 12 are inserted through the inner wall of the vertical insert 6, and the horizontal inserts 12 are connected to the inner wall of the vertical insert 6 by elastic members (such as springs). The outer wall of the movable plate 11 is provided with several groups of protrusions 13 that push the horizontal insert 12 to move outward when it is downward. The vertical cross-section of the protrusion 13 is arc-shaped, and the end of the horizontal insert 12 is embedded with a ball that slides against the movable plate 11 and the protrusion 13.

[0051] After the sponge ring 9 absorbs water, its weight increases, causing the annular bottom plate to drive the movable plate 11 downward. The movable plate 11 pushes the horizontal insert 12 downward through the convex portion 13, so that one end of the horizontal insert 12 extends out of the outer wall of the vertical insert 6 and enters the wetland soil horizontally, thereby enhancing the fixing strength between the collecting tube 1 and the wetland soil, further improving the device's resistance to wave impact, and making it less likely to be displaced or out of position due to wave impact.

[0052] Example 5

[0053] Please see the attached Figure 4 -Attached Figure 5 On the basis of embodiment 4, the inner wall of the supporting base 5 is provided with a detection sensor 15 for contacting the top of the annular bottom plate. The detection sensor 15 is electrically connected to the controller. The detection sensor 15 includes, for example, a contact sensor or a pressure sensor.

[0054] Several groups of movable plates 17 are inserted into the inner wall of the bearing base 5 and at the position below the annular bottom plate. There is a certain distance between the movable plate 17 and the annular bottom plate, which does not affect the annular bottom plate driving the movable plate 11 downward to the desired position. At the same time, the position of the movable plate 17 is staggered with the vertical insert 6. One end of the movable plate 17 is in the movable opening opened on the outer wall of the bearing base 5, and the other end is adsorbed and connected with the magnetic ring 16. The magnetic ring 16 is provided on the inner wall of the bearing base 5, and the two are coaxial. The magnetic ring 16 is electrically connected to the controller for electrically adsorbing the movable plate 17. The movable plate 17 can be made of magnetic material. The movable plate 17 is slidably connected to the inner wall of the bearing base 5 and an elastic connecting member 18 is provided at the connection between the two. For example, a movable opening is provided on the movable plate 17, and a protrusion is provided on the inner wall of the bearing base 5. The protrusion is in the movable opening and is connected to the inner wall of one side of the movable opening through the elastic connecting member 18. The elastic connecting member 18 is, for example, a spring;

[0055] When the detection sensor 15 does not detect the annular bottom plate, the controller controls the magnetic ring 16 to be powered off, and then the movable plate 17 moves outward under the drive of the elastic connecting member 18;

[0056] After the sponge ring 9 absorbs water, its weight increases, causing the annular bottom plate to drive the movable plate 11 downward, and then the detection sensor 15 fails to detect the annular bottom plate, so that the magnetic ring 16 is powered off, and the elastic connector 18 drives the movable plate 17 to move outward and extend out of the supporting base 5, thereby increasing the contact area between the supporting base 5 and the soil at the location, so as to prevent the supporting base 5 from sinking due to the increased weight.

[0057] Preferably, several groups of one-way drain pipes 14 are inserted into the outer wall of the supporting base 5 of this embodiment, and the one-way drain pipes 14 are located between the movable plate 17 and the annular bottom plate. The one-way drain pipes 14 prevent external water from entering the supporting base 5 from the one-way drain pipes 14, but allow the water in the supporting base 5 to be discharged from the one-way drain pipes 14. Specifically, when the annular bottom plate drops to the lowest position, the top surface of the annular bottom plate is below the one-way drain pipes 14. In this way, the water that continues to enter the supporting base 5 through the annular liquid separating member 10 can be discharged from the one-way drain pipes 14.

[0058] Furthermore, an annular opening is provided on the top of the supporting base 5, and a detachable annular cover is provided at the annular opening to facilitate replacement of internal components such as the sponge ring 9.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
