Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coastal wetland soil monitoring, in particular to a soil respiration gas collecting device suitable for coastal wetlands. BACKGROUND

[0002] Coastal wetlands play an important role in global climate change, and in-depth study of the respiration of coastal wetland soil helps to evaluate and further explore the carbon sink function of coastal wetlands.

[0003] Currently, when collecting soil respiration gas in coastal wetlands, a bottomless box is usually buckled on the soil surface to form a closed space, and then gas samples in the box are collected every certain time, and the collected gas can be detected by detection sensors or equipment. This method can complete soil respiration gas collection and detection, but still has the following defects in use:

[0004] Due to the use in coastal wetland areas, the box is easily affected by wave impact and displaced or tilted, which not only affects stable gas collection and detection, but also reduces the service life of the box structure. Therefore, we propose a soil respiration gas collecting device suitable for coastal wetlands. SUMMARY

The top rod is arranged on the outer wall of the collecting cylinder. When the guide plate moves towards the collecting cylinder, the top rod drives the inner movable plate to move upwards relative to the guide plate, so that the through holes one and two correspond.

[0014] Further improvement is that a water guide is arranged below each of the through holes two in the horizontal row. One end of the water guide is connected to the side of the inner movable plate facing the collecting cylinder, and the other end forms a drainage channel with the inner wall of the guide plate.

[0015] Further improvement is that the inner cavity of the bearing base is provided with an annular bottom plate, and a sponge ring is arranged on the top of the annular bottom plate. An annular distribution member is arranged on the inner wall of the bearing base, and the water outlet end of the annular distribution member is in contact with the sponge ring. The water inlet end of the annular distribution member is connected to the guide plate through a pipeline.

[0016] Further improvement is that a moving plate is inserted at the top of the vertical insert. One end of the moving plate extends into the bearing base and is connected to the annular bottom plate. The annular bottom plate is slidingly arranged in the bearing base. An elastic member is arranged between the annular bottom plate and the inner wall of the bearing base. A plurality of groups of horizontal inserts are inserted through the inner wall of the vertical insert, and the horizontal inserts and the inner wall of the vertical insert are connected by elastic members.

The magnetic ring is arranged on the inner wall of the bearing base. The magnetic ring is electrically connected to the controller for energizing the movable plate. The movable plate is slidingly connected to the inner wall of the bearing base, and an elastic connecting member is arranged at the connection between the movable plate and the bearing base.

[0019] When the detection sensor does not detect the annular bottom plate, the controller controls the magnetic ring to be de-energized, and the movable plate moves outward under the driving of the elastic connecting member.

[0020] Further improvement is that a plurality of groups of one-way drainage pipes are inserted into the outer wall of the bearing base, and the one-way drainage pipes are arranged between the movable plates and the annular bottom plate.

[0035] A bearing base 5 is sleeved on the outer wall of the collection cylinder 1, and a plurality of groups of vertical inserts 6 for inserting into the soil of the coastal wetland are arranged on the bottom of the bearing base 5. Specifically, during installation, the user can insert the outer wall part of the collection cylinder 1 below the bearing base 5 into the wetland soil by foot power until the ground of the bearing base 5 is in contact with the surface of the wetland soil, and the vertical inserts 6 improve the stability of the collection cylinder 1 during use;

[0036] A protection mechanism 7 comprises a plurality of groups of V-shaped guide plates 71, and the plurality of groups of guide plates 71 are arranged in a ring array on the outer side of the circumference of the collection cylinder 1 and above the bearing base 5. Through the V-shaped guide plates 71, the impact force of the sea waves can be guided to the two sides and discharged when the collection cylinder 1 is impacted by the sea waves, so as to reduce the impact of the sea waves on the collection cylinder 1 and prevent the collection cylinder 1 from being separated from the position.

[0037] One side of the guide plate 71 is connected to the outer wall of the collection cylinder 1 through a plurality of groups of elastic buffers 8, such as elastic buffer rods or elastic damping buffers. Through the elastic buffers 8, the impact force can be further reduced when the guide plate 71 is impacted by the sea waves.

[0038] The outer wall of the bearing base 5 is provided with a connecting rope 20, one end of the connecting rope 20 can be connected to an insertion cone in the outside world, and the insertion cone is inserted into a suitable position or is bound in a suitable position through the connecting rope 20, so that the collecting cylinder 1 is not driven into the sea by the sea waves when the collecting cylinder 1 is separated from the position due to the impact of the sea waves, and the device is lost;

[0040] Embodiment 2

[0041] Please refer to the accompanying Figure 2 -Appendix Figure 3 On the basis of embodiment 1, the protection mechanism 7 of the present embodiment further comprises:

[0042] The inner movable plate 73 is inserted into the top of the guide plate 71 and is connected to the inner wall of the guide plate 71 through a spring (not shown in the figure). The inner movable plate 73 is uniformly provided with through holes two 74. The side of the guide plate 71 away from the collecting cylinder 1 is uniformly provided with through holes one 72. When the guide plate 71 does not move towards the collecting cylinder 1, the through holes two 74 and the through holes one 72 do not correspond, and the water in the outside world cannot enter the guide plate 71, and the particles (soil) in the outside world are also not easy to block the through holes one 72.

[0043] The wedge-shaped block 75 is a right trapezoid and is arranged above the guide plate 71 and connected to the inner movable plate 73. The inclined surface of the wedge-shaped block 75 is slidably connected to the top rod 77. The top rod 77 is arranged on the outer wall of the collecting cylinder 1. The end of the top rod 77 is embedded with a ball which is slidably connected to the inclined surface of the wedge-shaped block 75. When the guide plate 71 moves towards the collecting cylinder 1, the top rod 77 drives the inner movable plate 73 to move upwards relative to the guide plate 71, so that the through holes one 72 and the through holes two 74 correspond.

[0044] Under the impact of the sea waves, the guide plate 71 moves towards the collecting cylinder 1 and presses the elastic buffer 8. Then the top rod 77 drives the wedge-shaped block 75, and the wedge-shaped block 75 drives the inner movable plate 73 to move upwards relative to the guide plate 71, so that the through holes one 72 and the through holes two 74 correspond. The sea waves impacting the guide plate 71 can enter the guide plate 71 through the through holes one 72 and the through holes two 74. In this way, the impact force of the sea waves is further dispersed. 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] Embodiment 3

[0046] Please refer to the attached Figure 2 and the attached Figure 4 - the attached Figure 5 On the basis of example 2, the lower part of each horizontal through hole 74 of the present embodiment is provided with a water guide 76, one end of which 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. The water entering the inner cavity of the guide plate 71 through the through hole 74 is guided by the water guide 76 to enter the drainage channel. The water entering from the through hole 74 is far away from the through hole 74 when it is discharged downward, thereby reducing the water flowing downward in the guide plate 71 from the through hole 74 below;

[0047] The inner cavity of the bearing base 5 is provided with an annular bottom plate, and the top of the annular bottom plate is provided with a sponge ring 9. The inner wall of the bearing base 5 is provided with an annular distributor 10. The annular distributor 10 is a conventional structure in the art, which is an annular structure device for fluid distribution or collection, usually in the form of a circular ring, which uniformly distributes the entering water to the sponge ring 9 along the circumferential direction. The water outlet end of the annular distributor 10 is in contact with the sponge ring 9, and the water inlet end of the annular distributor 10 is connected to the guide plate 71 through a pipeline.

[0048] The water entering the guide plate 71 can enter the annular distributor 10, and then be absorbed by the sponge ring 9 from the annular distributor 10. After being absorbed by the sponge ring 9, the weight of the bearing base 5 is increased, and since the bearing base 5 is located at the lower end of the collecting cylinder 1, the center of gravity of the collecting cylinder 1 is lowered, thereby enhancing the stability of the collecting cylinder 1 against wave impact force.

[0049] Example 4

[0050] Please refer to the attached Figure 4 On the basis of example 3, the top of the vertical insert 6 of the present embodiment is provided with a moving plate 11, one end of which extends into the bearing base 5 and is connected to the annular bottom plate. The annular bottom plate is slidingly 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 arranged between the annular bottom plate and the inner wall of the bearing base 5. A plurality of 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 moving plate 11 is provided with a plurality of groups of convex portions 13 which top the horizontal inserts 12 to move outward when the moving plate 11 moves downward. The convex portions 13 have an arc-shaped vertical cross section. The end of the horizontal insert 12 is embedded with a ball which slidingly abuts against the moving plate 11 and the convex portions 13.

[0051] The sponge ring 9 absorbs water and increases in weight, so that the annular bottom plate drives the moving plate 11 to move downward, the moving plate 11 drives the horizontal insert 12 to move downward by the convex part 13, one end of the horizontal insert 12 extends out of the outer wall of the vertical insert 6 and enters the wetland soil horizontally, so that the fixing strength of the collecting cylinder 1 and the wetland soil is enhanced, and the anti-sea wave impact performance of the device is further improved, and the device is not easy to be displaced or separated from the position.

[0054] A plurality of groups of movable plates 17 are inserted at a position below the annular bottom plate in the inner wall of the bearing base 5, the movable plates 17 and the annular bottom plate have a certain spacing, which does not affect the annular bottom plate driving the moving plate 11 to move downward to the required position, and the positions of the movable plates 17 and the vertical insert 6 are staggered, one end of the movable plate 17 is in the movable opening of the outer wall of the bearing base 5, the other end is adsorbed and connected with the magnetic ring 16, the magnetic ring 16 is arranged on the inner wall of the bearing base 5, and the two are coaxial, the magnetic ring 16 is electrically connected to the controller, and is used for electrifying and adsorbing the movable plate 17, the movable plate 17 can be made of magnetic material, the movable plate 17 and the inner wall of the bearing base 5 are slidably connected, and an elastic connecting piece 18 is arranged at the connection position of the two, for example, the movable plate 17 is provided with a movable opening, the inner wall of the bearing base 5 is provided with a convex block, the convex block is in the movable opening and is connected with the inner wall of one side of the movable opening through the elastic connecting piece 18, and the elastic connecting piece 18 is a spring, for example.

[0055] When the detection sensor 15 does not detect the annular bottom plate, the controller controls the magnetic ring 16 to be de-energized, and then the movable plate 17 moves outward under the drive of the elastic connecting piece 18.

[0056] The sponge ring 9 absorbs water and increases in weight, so that the annular bottom plate drives the moving plate 11 to move downward, and then the detection sensor 15 does not detect the annular bottom plate, so that the magnetic ring 16 is de-energized, and the elastic connecting piece 18 drives the movable plate 17 to move outward and extend out of the bearing base 5, so as to increase the contact area of the bearing base 5 and the soil in the position, so as to prevent the bearing base 5 from sinking due to the increase in weight.
