Description

Technical Field

[0001] This invention relates to the field of air quality monitoring technology, and in particular to a device for monitoring the carbon content in the air of bamboo forests at different heights. Background Technology

[0002] Monitoring the carbon content in the air of bamboo forests can provide important information about the carbon cycle and ecosystem health. The carbon content in the air is mainly measured by monitoring the concentration of carbon dioxide, as carbon dioxide is a major component of the carbon cycle.

[0003] A forest air quality monitoring device, as described in patent publication number CN115654341A, includes: a protective frame and a first sliding plate, with the first sliding plate slidably connected to the lower part of the protective frame; an air quality monitor, with the air quality monitor placed on the upper side of the first sliding plate; an installation mechanism, with the installation mechanism on the protective frame; and a pushing mechanism, with the pushing mechanism on the installation mechanism. When the first sliding plate moves upwards from the protective frame, it automatically moves to the right, exposing the air quality monitor to the air, thus enabling the monitoring of air quality in the forest area and improving the accuracy of the monitoring results. However, when monitoring air quality at high altitudes, the device needs to be placed at a high position, increasing the load on vegetation and making operation inconvenient.

[0004] Therefore, in order to address the above problems, we are now developing a device for monitoring the carbon content in the air of bamboo forests at different heights, which can facilitate the monitoring of air quality at different heights and reduce the load on plants.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] A device for monitoring air carbon content in bamboo forests at different heights, such as... Figure 1 and Figure 2As shown, it includes a placement frame 1, a sliding plate 2, a monitoring component 3, a vent pipe 4, an air inlet pipe 5, an observation plate 6, and a lifting mechanism 7. The sliding plate 2 is slidably connected inside the placement frame 1. The monitoring component 3 for monitoring the carbon content of the air is connected to the sliding plate 2. The vent pipe 4 is connected to the right side of the monitoring component 3. The air inlet pipe 5 for extracting air is connected to the left end of the vent pipe 4. The observation plate 6 for observing the internal conditions is slidably connected to the front side of the placement frame 1. A handle for easy pulling is connected to the front left side of the observation plate 6. The placement frame 1 is equipped with a lifting mechanism 7 for automatically raising and lowering the air inlet pipe 5.

[0032] It should be noted that during the bamboo growth process, it is necessary to monitor the carbon content in the air inside the bamboo forest in real time. At this time, this device can be installed in the bamboo forest. First, place the placement frame 1 in a suitable position. When monitoring, start the lifting mechanism 7 to drive the air intake pipe 5 to rise, so as to adapt to bamboo forests of different heights for air detection. Air is drawn in through the air intake pipe 5 and enters the monitoring component 3 through the ventilation pipe 4 for monitoring. The staff can pull open the observation plate 6 to the right to observe the monitoring component 3.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the lifting mechanism 7 includes a mounting frame 71, sliding members 72, connecting rods 73, connecting shafts 74, racks 75, gears 76, pulley assembly 77, dual-shaft motor 78, and a first connecting plate 79. The mounting frame 71 is connected to the left side of the placement frame 1. Sliding members 72, symmetrically arranged front and rear, are slidably connected to the bottom of the mounting frame 71. Connecting rods 73 are rotatably connected to each sliding member 72. Connecting shafts 74 are rotatably connected between the connecting rods 73. Adjacent connecting rods 73 are rotatably connected to each other. Sliding members 72 are rotatably connected to the top of each connecting rod 73. The first connecting plate 79 is slidably connected between the upper sliding members 72. The first connecting plate 79 is connected to the air intake. The tube 5 is connected, and the bottommost connecting shaft 74 is connected to racks 75 on both sides. The racks 75 are slidably connected to the mounting frame 71. Inside the mounting frame 71, gears 76 that mesh with the adjacent racks 75 are rotatably connected to both sides. The rear side of the mounting frame 71 is connected to a dual-axis motor 78 by bolts. The output shaft of the dual-axis motor 78 is set to the left and right. The output shaft of the dual-axis motor 78 and the corresponding gear 76 are connected to pulley assemblies 77. Each pulley assembly 77 includes a pulley and a drive belt. The output shaft of the dual-axis motor 78 and the outer side of the gear 76 are connected to pulleys. A drive belt is wound between adjacent pulleys.

[0034] It should be noted that when monitoring air carbon content in bamboo forests at different heights, the dual-shaft motor 78 can be activated to rotate its output shaft. This causes the pulley assembly 77 to drive the adjacent gears 76 to rotate. As the gears 76 begin to rotate, the adjacent racks 75 slide upwards along the inner wall of the mounting frame 71, causing the racks 75 to drive the adjacent connecting shafts 74 to move upwards. This, in turn, causes the connecting rods 73 to rotate and retract relative to each other. At this time, the lower sliding parts 72 slide closer together along the bottom of the mounting frame 71. When the connecting rods 73 begin to rotate and retract, they will push against each other. The upper sliding member 72 is moved upward, causing all upper sliding members 72 to slide along the first connecting plate 79. As the upper sliding member 72 moves upward, it will drive the air intake pipe 5 upward, thereby adapting to bamboo forests of different heights, improving adaptability during the monitoring process, reducing monitoring errors, and improving monitoring accuracy. In summary, the output shaft of the dual-axis motor 78 drives the gear 76 to rotate, thereby causing the rack 75 to drive the connecting rod 73 to move and lift, which in turn causes the first connecting plate 79 to drive the air intake pipe 5 to lift, making it convenient to monitor the carbon content in the air for bamboo forests of different heights, improving operational convenience while reducing monitoring errors and improving monitoring accuracy.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a take-up mechanism 8, which includes a protective frame 81, a limiting member 82, a drive motor 83, a rotating roller 84, and a friction belt 85. The top of the placement frame 1 is bolted to a protective frame 81 for protecting the vent pipe 4. Inside the protective frame 81, there is a limiting member 82 for limiting and winding the vent pipe 4. The upper front and rear sides of the protective frame 81 are bolted to drive motors 83, and the output shaft of the drive motor 83 is oriented downwards. Rotating rollers 84 are rotatably connected to the front and rear sides inside the protective frame 81. The left rotating rollers 84 are connected to the output shaft of the adjacent drive motor 83. Friction belts 85 for driving the vent pipe 4 to take up are wound between the left and right adjacent rotating rollers 84.

[0036] It should be noted that, to prevent the vent pipe 4 from being continuously pulled out during the lifting of the intake pipe 5, causing it to become tangled and knotted, the vent pipe 4 is restrained by the protective frame 81 and the limiting member 82. When the vent pipe 4 is pulled out, it will move along the limiting member 82 and the protective frame 81, thus preventing tangling and knotting. After the monitoring is completed, as the intake pipe 5 returns to its initial position, the vent pipe 4 will accumulate on top of the placement frame 1 due to excessive pulling out. At this time, the drive motor 83 can be started. The output shaft of the drive motor 83 will rotate, driving... The rotating roller 84 rotates, causing the friction belt 85 to rotate as well. This friction pulls the vent pipe 4, causing it to begin winding and resetting along the limiting member 82 and the protective frame 81, achieving a rapid winding effect. Once winding is complete, the drive motor 83 can be turned off. In summary, the limiting member 82 and the protective frame 81 guide the vent pipe 4, preventing it from tangling or knotting. After monitoring, the output shaft of the drive motor 83 drives the friction belt 85 to rotate, thereby winding and resetting the vent pipe 4 and preventing it from accumulating.

[0037] like Figure 1 and Figure 7 As shown, it also includes a stabilizing mechanism 9, which includes a fixing plate 91, a sleeve assembly 92, and a second connecting plate 93. The fixing plate 91 is bolted to the upper front side of the mounting frame 71. The sleeve assembly 92 is connected to the fixing plate 91, and the second connecting plate 93, which is engaged with the first connecting plate 79, is connected to the sleeve assembly 92.

[0038] It should be noted that when the first connecting plate 79 drives the intake pipe 5 to rise upwards for air monitoring at higher altitudes, the first connecting plate 79 will engage with the second connecting plate 93 after rising to a certain height. Subsequently, as the first connecting plate 79 continues to rise, it will push the second connecting plate 93 upwards, thereby extending the sleeve assembly 92 to assist the first connecting plate 79 in rising and making the lifting process of the first connecting plate 79 more stable. In summary, by engaging with the second connecting plate 93 during the rising process, the sleeve assembly 92 extends, assisting the first connecting plate 79 and the second connecting plate 93 to rise synchronously, thus improving the stability of the intake pipe 5 during the lifting process.

[0039] like Figure 1 , Figure 8 and Figure 9As shown, it also includes a protective mechanism 10, which includes a first fixing frame 101, a protective sleeve 102, a spring 103, and a connecting rod 104. The first fixing frame 101 is bolted to the upper left side of the placement frame 1. The left side of the vent pipe 4 is fitted with a protective sleeve 102 to prevent the vent pipe 4 from being damaged or bent. The front right side of the protective sleeve 102 is connected to a connecting rod 104 that is slidably connected to the first fixing frame 101. A spring 103 is connected between the connecting rod 104 and the first fixing frame 101.

[0040] It should be noted that as the intake pipe 5 moves upward, it will cause the vent pipe 4 to move and bend. At the same time, during the upward movement of the intake pipe 5, the protective sleeve 102 will bend synchronously, which will cause the connecting rod 104 to slide upward along the first fixing frame 101. During this process, the spring 103 is always under tension, thereby maintaining the state of the protective sleeve 102. In summary, the bending of the protective sleeve 102 protects the bent part of the vent pipe 4 and avoids damage caused by excessive bending of the vent pipe 4.

[0041] like Figure 1 and Figure 10 As shown, it also includes a locking mechanism 11, which includes a second fixed frame 111, a locking frame 112 and a torsion spring 113. The second fixed frame 111 is bolted to the upper right side of the sleeve assembly 92. The locking frame 112 for locking the first connecting plate 79 is rotatably connected to the second connecting plate 93. The locking frame 112 is slidably connected to the second fixed frame 111. The torsion spring 113 is connected between the locking frame 112 and the second connecting plate 93 and is wound around the locking frame 112.

[0042] It should be noted that as the second connecting plate 93 moves upward, it drives the locking frame 112 to slide upward along the second fixed frame 111. Initially, the torsion spring 113 is in a state of deformation. After the locking frame 112 moves upward along the second fixed frame 111 for a certain distance, under the action of the torsion spring 113, the locking frame 112 will rotate to the left and engage with the first connecting plate 79, thereby locking the first connecting plate 79 and preventing it from disengaging from the second connecting plate 93. After the monitoring is completed, as the second connecting plate 93 moves downward to reset, the locking frame 112 will once again engage with the second connecting plate 93. The fixing frame 111 returns to the sliding connection state. Then, guided by the second fixing frame 111, the locking frame 112 will rotate to the right to reset, so that the torsion spring 113 returns to the stress deformation state, thereby making the first connecting plate 79 no longer locked, which facilitates the disengagement of the first connecting plate 79 and the second connecting plate 93. In summary, by guiding the locking frame 112 through the second fixing frame 111, when the first connecting plate 79 and the second connecting plate 93 are engaged and moving upward, the locking frame 112 locks the first connecting plate 79, preventing the first connecting plate 79 and the second connecting plate 93 from disengaging during the upward movement.

[0043] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes a fixing mechanism 12, which includes a third fixing frame 121, a clip 122 and an annular fixing member 123. The third fixing frame 121 is bolted to the rear side of the placement frame 1. Two annular fixing members 123 are rotatably connected to the right rear side of the third fixing frame 121. Two clips 122 for locking the annular fixing members 123 are rotatably connected to the left side of the third fixing frame 121.

[0044] It should be noted that when installing the placement frame 1, the placement frame 1 can be snapped into place with the bamboo by rotating the annular fixing part 123 and the clip 122.

[0045] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
