[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that, in the absence of conflict, the embodiments in this disclosure and the feature vectors in the embodiments can be arbitrarily combined with each other.

[0029] However, in field work, we often encounter sampling sites with complex terrain and restricted surrounding conditions. The widely used gas collection devices are usually fixed in shape and bulky in size, which is not conducive to transportation and cannot be adapted to all sites. This not only causes manpower consumption, but also affects the quality of gas collection or monitoring. Therefore, there is an urgent need for a lightweight, variable-structured gas collection / monitoring device suitable for multiple sites.

[0030] In order to solve the problems existing in the related art, the embodiment of the present disclosure provides a gas collection device, which includes multiple bases and multiple side wall plates. The multiple bases are split structures, and the multiple side wall plates are connected head to tail in sequence to form a hollow cylinder. The bottom of the hollow cylinder is connected to the base, wherein adjacent side wall plates can be flipped around a preset rotation axis, and the axial direction of the preset rotation axis is parallel to the height direction of the hollow cylinder. In the present disclosure, the multiple side wall plates are connected head to tail in sequence to form a hollow cylinder, and the adjacent side wall plates can be flipped around a preset rotation axis. The hollow body and the multiple split bases cooperate to enclose to form a gas collection device. The side wall plates can be folded according to the spatial shape and size of the use scene to adjust the shape of the hollow cylinder, and the number of bases can be adaptively selected to adapt to the shape of the hollow cylinder, and then assembled to form a gas collection device that adapts to different scenes.

[0031] In order to make the purpose, technical solution and beneficial effects of the embodiments of the present disclosure more clear, a gas collection device provided by the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.

[0032] According to the disclosed exemplary embodiments, Figures 1 to 7 As shown, the gas collection device includes a plurality of bases 1 and a plurality of sidewall plates 2, and the plurality of bases 1 are split structures. Figure 3 As shown, four bases 1 are provided, the ends of the four bases 1 are connected to each other, the four bases 1 form a square, and the structure of each base 1 is F-shaped, and a threaded hole is provided on one side of the F-shaped base 1, so that a fastener 12 (such as a screw) passes through the threaded hole to fix the base 1 to the ground of the desired sampling site to avoid tilting and movement. In another example, as Figure 6 As shown, there are six bases 1, and the ends of the six bases 1 are connected in sequence to form a hexagon, so that the multiple bases 1 are stably set on the ground of the required sampling site, wherein each base 1 is made of aluminum alloy. Under the condition of complex terrain of the sampling site, aluminum alloy has the characteristics of corrosion resistance, high strength, and light weight, which can extend the service life and is easy to carry. This does not limit the technical solution of the present disclosure, and the number of bases 1 and the shape of the graphics formed by the bases can be adaptively selected according to actual needs.

[0033] like Figure 1 Shown and Figure 7 As shown, the gas collection device also includes a plurality of side wall plates 2, the head and tail of the plurality of side wall plates 2 are sequentially connected to form a hollow cylinder 21, the bottom of the hollow cylinder 21 is connected to the base 1, wherein the adjacent side wall plates 2 can be turned around a preset rotation axis, so that the plurality of side wall plates 2 can be folded and unfolded, which is convenient for storage and does not occupy space, and the axial direction of the preset rotation axis (such as Figure 1 The z direction shown in FIG. 2 ) and the height direction of the hollow cylinder 21 (as shown in FIG. Figure 1 The shape of the gas collection device formed by folding the plurality of side wall panels 2 can be adjusted. For example, when all the side wall panels 2 are unfolded, the side wall panels 2 can be enclosed to form a large hollow cylinder 21. When the side wall panels 2 are not fully unfolded, that is, when some of the side wall panels 2 are in a folded state, the plurality of side wall panels 2 can be enclosed to form a small hollow cylinder 21. Figure 7 The figure shows a folded state of a plurality of side wall panels 2. The number of side wall panels 2 provided may be the same as the number of base panels 1 provided, or the number of side wall panels 2 provided may be different from the number of base panels 1 provided. Figure 1, the number of the plurality of side wall panels 2 is the same as the number of the base 1, the side wall panels 2 are connected to the base 1, there are four side wall panels 2, the four side wall panels 2 are connected end to end in sequence and the four side wall panels 2 are all unfolded to enclose a hollow quadrangular prism, and in the subsequent process, the gas in the space enclosed by the hollow quadrangular prism can be collected and detected. In another example (not shown in the drawings), there are four side wall panels, but there are two side wall panels stacked, so that the four side wall panels enclose a hollow triangular prism.

[0034] In the present invention, multiple side wall panels are connected end to end in sequence to form a hollow cylinder, and adjacent side wall panels can be flipped around a preset rotation axis. The hollow cylinder and multiple separate bases cooperate to enclose a gas collection device. The side wall panels can be folded to adjust the shape of the hollow cylinder according to the spatial shape and size of the usage scene, and the number of bases can be adaptively selected to adapt to the shape of the hollow cylinder, thereby assembling to form a gas collection device that can adapt to different scenes. The gas collection device has a simple structure, can be quickly folded and unfolded, is light in material, and has a low cost. It is easy to store and transport after folding.

[0035] In some embodiments, Figure 1 As shown, the material of each side wall panel 2 can be a hard material, and two adjacent side wall panels 2 can be connected by a flexible material, so that the two adjacent side wall panels can be folded. In one example, the material of each side wall panel 2 is hard plastic, which has the characteristics of high strength, wear resistance and corrosion resistance. The flexible material between the two adjacent side wall panels 2 can be rubber, which is a highly elastic material with reversible deformation, so that each side wall panel 2 can be flipped around a preset rotation axis, and can be unfolded for use and folded for storage, and there is no gap at the connection of the two connected side wall panels 2.

[0036] In some embodiments, Figures 1 to 3 As shown, a plurality of bases 1 and a plurality of side wall panels 2 are arranged one by one, and each base 1 is connected to a corresponding side wall panel 2. Figure 2 In the x direction shown, the extension length of the base 1 and the length of the side wall plate 2 can be set accordingly as required. In one example, Figure 2 In the x direction shown, the length of each base 1 is the same as the length of each side wall plate 2 , and the side wall plate 2 having the same length as the base 1 can be placed inside the base 1 and can match with the base 1 .

[0037] In some embodiments, Figures 1 to 6 As shown, the gas collection device further includes a sealing gasket 3, which may be an annular structure. The sealing gasket is made of a flexible material and can produce adaptive deformation according to the shape formed by the multiple bases during use. Figure 4As shown, the sealing gasket 3 is annular in structure, and the sealing gasket 3 is located between the base 1 and the side wall plate 2 , and the sealing gasket 3 is connected to the base 1 and the side wall plate 2 , and the sealing gasket 3 is used to seal the connection between the base 1 and the side wall plate 2 .

[0038] In some embodiments, Figures 4 to 6 As shown, the top of the sealing gasket 3 has a first accommodating groove 31, and the shape of the first accommodating groove 31 can be set accordingly as required. Figure 4 As shown, the longitudinal section of the sealing gasket 3 is U-shaped, and the first accommodating groove 31 is a circular groove.

[0039] In some embodiments, Figures 1 to 4 As shown, the side wall plate 2 is connected to the sealing gasket 3, and the bottom of the side wall plate 2 is located in the first receiving groove 31, wherein the first receiving groove 31 contains a sealing fluid 4, and the sealing fluid 4 is used to seal the gap between the side wall plate 2 and the first receiving groove 31 to prevent gas leakage in the hollow cylinder 21. The sealing fluid 4 can be a fluid such as oil or water, as long as it can seal the gap between the bottom of the side wall plate 2 and the first receiving groove 31. In this regard, there is no excessive limitation in the present disclosure. The side wall plate 2 fits with the first receiving groove 31 through the sealing fluid 4, so that a seal is formed between the side wall plate 2 and the sealing gasket 3, avoiding gas exchange between the internal space and the external space of the gas collection device, and avoiding inaccurate composition of the collected gas.

[0040] In some embodiments, Figure 3 As shown, the base 1 is provided with a second receiving groove 11, and the structure of the second receiving groove 11 can be adapted as required. In one example, continue to refer to Figure 3 , Figure 5 and Figure 6 As shown, the shape of the second receiving groove 11 is a strip groove, and the extension direction of the second receiving groove 11 (such as Figure 3 The x direction shown in FIG) and the extension direction of the base 1 (as shown in FIG Figure 3 The shape formed by the second receiving grooves 11 of the multiple bases 1 can be rectangular, hexagonal, etc., wherein the sealing gasket 3 is arranged in the second receiving grooves 11 of the multiple bases 1, and the opening direction of the first receiving groove 31 is the same as the opening direction of the second receiving groove 11.

[0041] In some embodiments, Figures 1 to 6 As shown, the sealing gasket 3 is in contact with the side wall of each base 1. In one example, the sealing gasket 3 is connected to the side wall of the second accommodating groove 11 in each base 1, so that each base 1 and each side wall plate 2 are double-sealed by the sealing gasket 3 and the sealing fluid 4, so as to prevent the gas inside the hollow cylinder 21 from being mixed with the external gas, thereby affecting the results of the subsequent gas collection.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the gas collection device also includes a top plate 5, which is located on the top of the multiple side wall plates 2. The shape and structure of the top plate 5 can be adapted according to the shape and structure formed by the multiple side wall plates 2. The top plate 5 and the multiple side wall plates 2 form a closed space in the hollow column 21. The top plate 5 is connected to the multiple side wall plates 2 by a snap connection, a rotation connection, etc. The material of the top plate 5 is a soft material. In one example, Figure 1 As shown, the shape of the top plate 5 is consistent with the shape formed by the multiple side wall plates 2. The top plate 5 is in the shape of a cube, and the material of the top plate 5 is plastic. Plastic is airtight and watertight, which prevents external gas and impurities from entering the hollow column 21, thereby affecting the collected gas. Figure 2 As shown, a fan 6 is provided on one side of the top plate 5 facing the hollow cylinder 21 . The fan 6 is fixed on the top plate 5 . The fan 6 is used to stir the gas in the hollow cylinder 21 at any time.

[0043] In some embodiments, continue to refer to Figure 2 The gas collection device is provided with a gas collection nozzle 7, which is used to control the gas in and out of the hollow cylinder 21 and maintain the seal after the gas in and out. The gas collection nozzle 7 can be installed on the side of the side wall plate 2, or on the top plate 5. The material of the gas collection nozzle 7 can be flexibly set according to the needs. In one example, the material of the gas collection nozzle 7 is copper, and the copper gas collection nozzle 7 is strong, durable, and has a long service life. The gas collection nozzle 7 is located on the top of the top plate 5 and is bonded to the top plate 5. When the gas collection device is collecting, the collected gas is collected through the gas collection nozzle 7.

[0044] The steps of using a gas collection device disclosed in the present invention are as follows:

[0045] like Figures 1 to 7 As shown, first, a corresponding number of bases 1 are set as required, the ends of a corresponding number of bases 1 are connected to form a required shape, and placed in appropriate positions for collecting gas, and this position is kept stationary, multiple bases 1 are fixed by fasteners 12, and the sealing gasket 3 is placed in the second receiving groove 11 of the base 1.

[0046] Next, unfold and install a plurality of side wall panels 2 corresponding to the base 1 into the first receiving groove 31 of the sealing gasket 3, and inject a sealing fluid 4 into the first receiving groove 31. Since the sealing fluid 4 is accommodated between the plurality of side wall panels 2 and the base 1, the sealing fluid 4 is used to cut off the gas exchange between the hollow cylinder 21 and the external environment. A top plate 5 is provided on the top of the plurality of side wall panels 2. The hollow cylinder 21 formed by the top plate 5 and the plurality of side wall panels 2 constitutes a closed space, so that the gas in the hollow cylinder 21 is only the gas to be collected.

[0047] Then, during the collection process, the fan 6 installed on the top plate 5 can be turned on as needed to rotate at a low speed to facilitate moderate stirring of the gas in the hollow cylinder 21, so that the gas in the hollow cylinder 21 is as uniform as possible, which is convenient for accurate collection of gas data later.

[0048] Finally, the collected gas is collected and discharged and collected through the gas collection nozzle 7 installed on the top plate 5. Then, the required collection site is selected to continue gas collection and the above steps are repeated. After the gas collection is completed, the top plate 5 is removed from the multiple side wall plates 2, and the multiple side wall plates 2 are flipped around the preset rotation axis again for folding and storage. At the same time, the multiple bases 1 are also removed from the ground of the required sampling site and stored, thereby completing the gas collection work.
