Description

Technical Field

[0001] This utility model relates to the field of greenhouse gas sampling, specifically a greenhouse gas sampling device applicable to multiple scenarios. Background Technology

[0002] Climate warming caused by greenhouse gas emissions has become one of the most important environmental problems facing the world. Monitoring and accounting of greenhouse gas emissions is the foundation for carrying out carbon emission reduction work. Urban sewage treatment systems, as an important part of municipal infrastructure, are also one of the major sources of carbon emissions.

[0003] For example, utility model publication (announcement number: CN221350771U) discloses a greenhouse gas emission sampling device, including a panel and an installation structure that can be fixed to online monitoring instruments of different specifications. A sampling box with an open bottom is vertically fixed to the lower surface of the panel, and the top of the sampling box extends to the upper surface of the panel. A floating device is detachably installed on the lower surface of the panel. This greenhouse gas emission sampling device allows the sampling box to float on the water surface after being placed in the water body to be monitored, supported by the floating device. An air chamber is formed at the top of the sampling box's inner cavity, allowing the online monitoring instrument to monitor the gas in the air chamber at the top of the sampling box. During use, two sliders can move on the surface of the guide rail, enabling installation and use with online monitoring instruments of different specifications, thus facilitating greenhouse gas emission sampling.

[0004] The aforementioned utility model device can be adapted to online monitoring instruments of different specifications for installation and use, which is beneficial for greenhouse gas emission sampling. However, the aforementioned utility model device is only applicable to water surfaces with a certain depth. Since the water level in paddy fields is relatively shallow, the aforementioned utility model device is not convenient to use in paddy fields for greenhouse gas sampling. Therefore, this application proposes a greenhouse gas sampling device applicable to multiple scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a greenhouse gas sampling device applicable to multiple scenarios, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse gas sampling device applicable to multiple scenarios, comprising a panel, a sampling box with an open bottom fixedly connected to the bottom end of the panel, and a floating device fixedly installed on the bottom end of the panel outside the sampling box; adjusting rods slidingly through both sides of the panel in a vertical direction, and limiting components that are inserted and cooperate with each adjusting rod fixedly connected to the top end of the panel; a thermometer and a pressure gauge fixedly installed on the top end of the sampling box, and the sensing ends of the thermometer and pressure gauge extending to the top of the inner cavity of the sampling box; and a circulation pipe and an air inlet pipe vertically connected to the top end of the sampling box.

[0007] Preferably, each of the adjusting rods has a top block fixedly connected to its top end, and each top block has a connecting ring fixedly installed at its top end.

[0008] Preferably, each of the connecting rings is tied and fixed to one end of the connecting rope.

[0009] Preferably, each of the limiting components includes a mounting cylinder fixedly connected to the top of the panel, and a sliding plate is slidably connected inside the mounting cylinder in the horizontal direction.

[0010] Preferably, each of the mounting cylinders is fixedly connected to a first mounting cover plate and a second mounting cover plate at both ends, and a limit block and a pull rod are fixedly connected to both ends of the slide plate.

[0011] Preferably, the limiting insert is slidably connected to the center position of the first mounting cover plate, and the pull rod is slidably connected to the center position of the second mounting cover plate. A spring is sleeved on the outside of the pull rod, and the two ends of the spring abut against the end of the slide plate near the second mounting cover plate and the end of the second mounting cover plate near the slide plate, respectively.

[0012] Preferably, the end of the pull rod away from the mounting cylinder is fixedly connected to a handle, and each adjusting rod has several limiting slots that are inserted and cooperate with the limiting blocks in the vertical direction, and each adjusting rod has a tapered insertion part at its bottom end.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention, when sampling greenhouse gases in water of a certain depth, involves pulling each adjusting rod to its highest position. This allows the limiting blocks of each limiting component to engage with the limiting slots at the bottom of the adjusting rod, thus limiting the position of each rod. The panel is then placed on the water surface, and a floating device at the bottom of the panel allows the sampling box to float. A gas chamber is formed at the top of the sampling box's inner cavity. An online monitoring instrument can then monitor the gas in this gas chamber. The thermometer and pressure gauge are used to monitor the temperature and pressure of the gas within the sampling box's gas chamber, a feature already fully disclosed in existing technology and will not be elaborated upon here. The air inlet of the online monitoring instrument is connected to an air inlet pipe, allowing it to draw gas from the top of the sampling box's inner cavity. The monitored exhaust gas then re-enters the gas chamber through several circulation holes on a circulation pipe, achieving efficient and rapid circulation. This is achieved through online monitoring... The instrument monitors the gas accumulation rate to calculate the greenhouse gas production rate. When sampling greenhouse gases in shallow water surfaces such as paddy fields, the adjusting rods are pulled vertically downwards to the designated positions. The spring elasticity causes the sliding plate to engage with the limiting slots of each adjusting rod, thus fixing the bottom of each adjusting rod to the soil of the paddy field. The multiple limiting slots on the adjusting rods allow for unified adjustment of the height of multiple adjusting rods. At the same time, the height of the bottom of the adjusting rods can be adjusted according to the actual water level, allowing the sampling box to be better positioned for sampling greenhouse gases at different water levels. A connecting ring is provided at the top of the top block of each adjusting rod. The two ends of each connecting rope are tied to one end of each connecting ring, making it convenient for the operator to deploy and retrieve the device using the connecting ropes.

[0018] 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.

[0019] Example

[0020] Please see Figures 1-2 The illustration shows a greenhouse gas sampling device applicable to multiple scenarios, including a panel 1. A sampling box 2 with an open bottom is fixedly connected to the bottom of the panel 1, and a floating device 3 is fixedly installed on the bottom of the panel 1 outside the sampling box 2. Adjusting rods 4 are slidably installed on both sides of the panel 1 in the vertical direction, and limiting components 5 that are inserted and cooperate with each adjusting rod 4 are fixedly connected to the top of the panel 1. A thermometer 11 and a pressure gauge 12 are fixedly installed on the top of the sampling box 2, and the sensing ends of the thermometer 11 and the pressure gauge 12 extend to the top of the inner cavity of the sampling box 2. A circulation pipe 9 and an air inlet pipe 10 are vertically connected to the top of the sampling box 2.

[0021] In this embodiment, a top block 6 is fixedly connected to the top of each adjusting rod 4, and a connecting ring 7 is fixedly installed on the top of each top block 6. Each connecting ring 7 is tied to one end of a connecting rope 8. Each limiting component 5 includes a mounting cylinder 51 fixedly connected to the top of the panel 1, and a sliding plate 54 is slidably connected to the mounting cylinder 51 in the horizontal direction. A first mounting cover plate 52 and a second mounting cover plate 53 are fixedly connected to both ends of each mounting cylinder 51, and a limiting insert 55 and a pull rod 56 are fixedly connected to both ends of the sliding plate 54. The limiting insert 55 and the pull rod 56 are connected to the limit insert 55 and the pull rod 56 respectively. The first mounting cover plate 52 is slidably through the center, and the pull rod 56 is slidably through the center of the second mounting cover plate 53. A spring is sleeved on the outside of the pull rod 56, and the two ends of the spring abut against the end of the slide plate 54 near the second mounting cover plate 53 and the end of the second mounting cover plate 53 near the slide plate 54, respectively. A handle 57 is fixedly connected to the end of the pull rod 56 away from the mounting cylinder 51. Each adjusting rod 4 has several limiting slots 401 that are inserted and cooperate with the limiting plug 55 in the vertical direction. Each adjusting rod 4 has a tapered insertion part at the bottom.

[0022] Furthermore, when sampling greenhouse gases in water at a certain depth, each adjusting rod 4 is pulled to its highest position, causing the limiting insert 55 of each limiting component 5 to engage with the limiting slot 401 at the bottom of the adjusting rod 4, thereby limiting the position of each adjusting rod 4. Then, the panel 1 is placed on the water surface, and the sampling box 2 floats on the water surface through the floating device 3 at the bottom of the panel 1. A gas chamber is formed at the top of the inner cavity of the sampling box 2, and the online monitoring instrument can monitor the gas in the gas chamber at the top of the inner cavity of the sampling box 2. The thermometer 11 and pressure gauge 12 are used to monitor the temperature and pressure of the gas in the gas chamber of the sampling box 2, which are fully disclosed in the prior art and will not be described in detail here. The air inlet of the online monitoring instrument is connected to the air inlet pipe 10, which can extract the gas chamber at the top of the inner cavity of the sampling box 2. The monitored exhaust gas then enters the gas chamber through several circulation holes on the circulation pipe 9 to achieve efficient and rapid circulation. The monitoring instrument monitors the gas accumulation rate to calculate the greenhouse gas production rate. When sampling greenhouse gases in shallow water surfaces such as paddy fields, the adjusting rod 4 is pulled vertically downwards to the designated position. The elasticity of the spring causes the sliding plate 54 to drive each limiting block 55 to engage with the limiting slot 401 of the adjusting rod 4, thus fixing the bottom of each adjusting rod 4 to the soil of the paddy field. The multiple limiting slots 401 on the adjusting rod 4 facilitate the unified adjustment of the height of multiple adjusting rods 4. At the same time, the height of the bottom of the adjusting rod 4 can be adjusted according to the actual water level, so that the sampling box 2 can be better adjusted to sample greenhouse gases at different water levels. A connecting ring 7 is provided on the top block 6 at the top of each adjusting rod 4. The two ends of each connecting rope 8 are tied to one end of each connecting ring 7, so that the operator can easily deploy and retrieve the device through the connecting rope 8.

[0023] The working principle of this utility model is as follows: When sampling greenhouse gases in water at a certain depth, each adjusting rod 4 is pulled to its highest position, so that the limiting block 55 of each limiting component 5 is engaged with the limiting slot 401 at the lowest point of the adjusting rod 4, thereby limiting the position of each adjusting rod 4. Then, the panel 1 is placed on the water surface, and the sampling box 2 floats on the water surface through the floating device 3 at the bottom of the panel 1. A gas chamber is formed at the top of the inner cavity of the sampling box 2. The online monitoring instrument can monitor the gas in the gas chamber at the top of the inner cavity of the sampling box 2. The thermometer 11 and pressure gauge 12 are used to monitor the temperature and pressure of the gas in the gas chamber of the sampling box 2. The air inlet of the online monitoring instrument is connected to the air inlet pipe 10, which can extract the gas chamber at the top of the inner cavity of the sampling box 2. The monitored exhaust gas then enters the gas chamber through several circulation holes on the circulation pipe 9 to achieve efficient and rapid circulation. The gas is monitored by the online monitoring instrument. The cumulative rate of greenhouse gas production is used to calculate the greenhouse gas production rate. When sampling greenhouse gases in shallow water surfaces such as paddy fields, the adjusting rod 4 is pulled vertically downwards to the designated position. The elasticity of the spring causes the sliding plate 54 to drive each limiting block 55 to engage with the limiting slot 401 of the adjusting rod 4, thus fixing the bottom of each adjusting rod 4 to the soil of the paddy field. The multiple limiting slots 401 on the adjusting rod 4 facilitate the uniform adjustment of the height of multiple adjusting rods 4. At the same time, the height of the bottom of the adjusting rod 4 can be adjusted according to the actual water level, so that the sampling box 2 can be better adjusted to sample greenhouse gases at different water levels. A connecting ring 7 is provided on the top block 6 at the top of each adjusting rod 4. The two ends of each connecting rope 8 are tied to one end of each connecting ring 7, so that the operator can easily deploy and retrieve the device through the connecting rope 8.
