Description

Technical Field

[0001] The invention belongs to the field of ecological observation devices, in particular to a mangrove trunk gas sampler and a use method thereof. Background Art

[0002] In greenhouse gas research, static chambers are used to collect soil greenhouse gases for various experiments. They are relatively mature and widely used equipment.

[0003] However, most of the existing greenhouse gas static boxes are used to collect greenhouse gases in water bodies and soil. Since trees do not have the sealing properties of soil and water surface, there are few static boxes that can be used in tree trunks, and most static boxes also have the defect of being inconvenient to disassemble and reuse. Summary of the Invention

[0004] Purpose of the invention: To provide a mangrove trunk gas sampler and a method of use, which, through the cooperation of a flexible body, a zipper, a drawstring adjuster and an adjustable drawstring, can enable the gas sampler to be applied to the trunk and can facilitate the disassembly and secondary use of the gas sampler.

[0005] The technical solution of the present invention is as follows: in a first aspect, a mangrove trunk gas sampler comprises: a flexible main body, a zipper, a sealing strip, a drawstring adjuster, an adjustable drawstring and a collecting piece.

[0006] The zippers are arranged at both ends of the flexible body, and the drawstring adjusters and the adjustable drawstrings are respectively arranged at both ends of the flexible body.

[0007] The sealing strip is arranged on one side of the flexible body, and the drawstring opening adjuster and the adjustable drawstring are arranged on the other side of the flexible body.

[0008] The flexible body is provided with a collection port, and the collection piece is installed at the collection port.

[0009] In a further embodiment of the first aspect, the mangrove trunk gas sampler further includes: a keel.

[0010] Several of the keels are distributed along the length direction of the flexible body. The keels do not limit the setting form of the sealing strip, which facilitates the installation of the sealing strip and allows the force of the strap adjustment device and the adjustable strap toward the trunk to be transmitted to the sealing strip through the keels.

[0011] In a further embodiment of the first aspect, the flexible body and the sealing strip can be separated and matched, so that the sealing strip can be freely bent during installation. When the tree trunk is small, the two ends of the sealing strip can be staggered and matched to achieve sealing between the flexible body and the two ends of the trunk, avoiding the problem of excessive overlap at the two ends of the sealing strip affecting the sealing performance.

[0012] In a further embodiment of the first aspect, the flexible main body and at least one end of the sealing strip can be separated and matched, so that at least one end of the sealing strip is in a freely bendable state during installation. When the tree trunk is small, the two ends of the sealing strip can be staggered and matched to achieve sealing between the flexible main body and the two ends of the trunk, avoiding the problem of excessive overlap at the two ends of the sealing strip affecting the sealing performance.

[0013] In a further embodiment of the first aspect, the detachable and mating parts of the flexible body and the sealing strip are connected by Velcro. The sealing strip can be first attached to the flexible body through the Velcro, and then the sealing strip can be installed between the flexible body and the tree trunk through the cooperation of the flexible body, the strap adjuster and the adjustable strap. When the sealing strip needs to be dislocated, the sealing strip can be installed on the flexible body according to the dislocation trajectory, which further facilitates the installation of the sealing strip. When the circumference of the tree trunk is too small, the flexible body can be further made into a pleated shape and connected to the sealing strip, so that the zipper can close the interface of the flexible body.

[0014] In a further embodiment of the first aspect, the flexible body is made of silicone material, which is soft and ductile and can maintain the stability of air pressure between the flexible body and the trunk when the trunk releases gas.

[0015] In a further embodiment of the first aspect, the zipper is a film waterproof zipper, which can form a good seal on the interface surrounded by the flexible body.

[0016] In a further embodiment of the first aspect, the sealing strip is made of rubber.

[0017] In a further embodiment of the first aspect, the collection port is provided with a rubber plug, through which a needle can be inserted between the flexible body and the trunk to collect gas. The sealing property is maintained after the gas is collected and the needle is pulled out after the collection is completed, thereby simplifying the gas collection steps.

[0018] In a second aspect, a method for using the mangrove trunk gas sampler based on the first aspect includes: in a further embodiment, one side of the flexible body provided with a sealing strip is enclosed around the trunk, so that the sealing strip fits the trunk.

[0019] A zipper is then used to seal the interface where the flexible body is enclosed.

[0020] The flexible body and sealing strip are then forced toward the tree trunk using the cinch adjuster and the adjustable cinch.

[0021] The beneficial effects of the present invention are: the present application can seal the interface of the flexible main body through the zipper and facilitate disassembly and multiple utilization; the sealing strip can space the flexible main body and the tree trunk at a certain distance and isolate the air; the flexible main body, the strap adjustment device and the adjustable strap can cooperate to adjust the diameter of the flexible main body when replacing different trunks; the collection piece can collect gas from between the flexible main body and the trunk, so that the gas sampler can form a sealed space on the trunk, and facilitate the disassembly and secondary utilization of the gas sampler, solving the problem that the gas sampler in the prior art cannot be used for tree trunks and is inconvenient to disassemble and reuse.

[0027] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0028] The present application discloses a mangrove trunk gas sampler and a method of use. By cooperating with a flexible body, a zipper, a drawstring adjuster and an adjustable drawstring, the gas sampler can be applied to the trunk and can be easily disassembled and reused.

[0029] like Figure 1 and 2 The mangrove trunk gas sampler shown includes: a flexible body 3, a zipper 7, a sealing strip 1, a strap adjustment device 5, an adjustable strap 2, a collection piece 6 and a keel 4.

[0030] The zippers 7 are provided at both ends of the flexible body 3 , and the drawstring adjusters 5 and the adjustable drawstrings 2 are provided at both ends of the flexible body 3 , respectively.

[0031] The sealing strip 1 is arranged on one side of the flexible body 3 , and the drawstring opening adjuster 5 and the adjustable drawstring 2 are arranged on the other side of the flexible body 3 .

[0032] The flexible body 3 is provided with a collecting port, and the collecting member 6 is installed at the collecting port.

[0033] Several keels 4 are distributed along the length direction of the flexible body 3 , wherein the keels 4 are rigid rods or rigid tubes extending along the width direction of the flexible body 3 .

[0034] In this embodiment, the flexible body 3 and the sealing strip 1 can be separated and matched.

[0035] In another embodiment, the flexible body 3 and at least one end of the sealing strip 1 can be detachably matched.

[0036] The flexible body 3 and the sealing strip 1 are separably connected by a Velcro 8. Figure 3 and 4 The flexible body 3 and the sealing strip 1 are integrally connected via a Velcro 8 .

[0037] like Figure 3 and 4 The width of the Velcro 8 is larger than the width of the sealing strip 1 , so that both ends of the sealing strip 1 can be attached to the Velcro 8 even after being misplaced.

[0038] The flexible body 3 is made of silicone, the zipper 7 is a film waterproof zipper 7, the sealing strip 1 is made of rubber, and the collecting piece 6 is a rubber plug.

[0039] The method for using the mangrove trunk gas sampler based on the above embodiment includes: enclosing one side of the flexible body 3 provided with the sealing strip 1 around the trunk, so that the sealing strip 1 fits the trunk.

[0040] Then, a zipper 7 is used to seal the interface surrounded by the flexible body 3 .

[0041] Then, the tie-off adjuster 5 and the adjustable tie 2 are used to apply a force toward the tree trunk to the flexible body 3 and the sealing strip 1 .
