Description

Technical Field

[0001] This invention relates to the field of air monitoring technology, and more particularly to a carbon monitoring device with photovoltaic solar energy storage. Background Technology

[0002] Carbon dioxide detection devices are widely used in outdoor environmental monitoring, industrial plant boundary control, ecological scientific research and observation and other scenarios. Their core function is to capture changes in carbon dioxide concentration in real time and provide data support for environmental governance, safe production and ecological research. For outdoor use scenarios, monitoring is easily affected by the weather. In windless weather, carbon dioxide is slightly denser than air and tends to accumulate locally, resulting in an uneven concentration distribution. Existing devices still maintain the conventional sampling frequency, which can easily lead to missed detection of local concentrations and data lag. In windy weather, the airflow will accelerate the diffusion of carbon dioxide and the concentration distribution will be relatively uniform.

[0003] In special scenarios such as high altitude and open outdoor spaces, wind conditions change frequently. However, the fixed working mode of existing technologies cannot adapt to complex airflow environments. When the wind direction changes, the sampling port is facing away from or to the side of the wind, and the airflow just brushes past the device, failing to effectively and continuously replenish the sampling port. This results in large deviations in the detection data, making it difficult to meet the needs of accurate monitoring. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a carbon monitoring device with photovoltaic solar energy storage. This invention utilizes wind power for steering, so that when the wind speed sensor detects a value higher than a preset value in windy weather, the motor does not operate. The wind resistance at the end of the sampling cylinder furthest from the detection chamber is increased by a wind deflector, thereby driving the sampling cylinder to rotate under the action of the wind. This makes the detection chamber face the wind direction, and the incoming air is blocked at the detection chamber, forming a local pressure stagnation zone. This forced stagnation of air is continuously replenished, greatly enhancing the air convection rate near the detection chamber. This, in turn, increases the airflow into the circulation channel, accelerates the air renewal rate on the surface of the carbon dioxide sensor, shortens the response time, and helps improve detection efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon monitoring device with photovoltaic solar energy storage, comprising a base, a sampling cylinder rotatably connected to the outer wall of the base, a detection chamber disposed inside the sampling cylinder, a mounting frame rotatably connected to the detection chamber via a rotating shaft, a carbon dioxide sensor fixed on the mounting frame, a motor for driving the mounting frame to rotate mounted on the outer wall of the detection chamber, a wind speed sensor and a control unit disposed inside the sampling cylinder, the wind speed sensor and the motor being electrically connected via the control unit, a wind baffle slidably connected to the outer wall of the sampling cylinder on the side away from the detection chamber, a transmission mechanism disposed inside the sampling cylinder, a coupling mechanism disposed on the rotating shaft of the mounting frame, and the motor starting the transmission mechanism via the coupling mechanism, causing the transmission mechanism to drive the sampling cylinder to rotate.

[0006] Preferably, the sampling tube has a flow channel that runs through the outer walls of both ends, the detection chamber is located at one end of the flow channel near the rotation center of the sampling tube, the sampling tube has a transmission chamber, and a sampling pump is installed on the outer wall of the sampling tube. The sampling pump is electrically connected to the wind speed sensor through a control unit.

[0007] Preferably, the transmission mechanism includes a small gear, a transmission gear, and a large gear rotatably connected in the transmission chamber. A fixed shaft rotatably inserted into the transmission chamber is installed on the outer wall of the base. The large gear is installed on the fixed shaft and meshes with the transmission gear. A synchronous belt for meshing transmission is provided between the small gear and the transmission gear. The small gear is installed on the rotating shaft of the mounting bracket.

[0008] Preferably, the coupling mechanism includes an electromagnetic clutch disposed in the transmission chamber, the driving end of the electromagnetic clutch is fixedly connected to the rotating shaft of the mounting bracket, and its driven end is fixedly connected to the rotating shaft of the pinion. The electromagnetic clutch is electrically connected to the wind speed sensor through a control unit.

[0009] Preferably, an encoder is fixed on the inner wall of the detection chamber, the detection end of the encoder is fixed on the main shaft of the motor, and the encoder and the motor are electrically connected through a control unit.

[0010] Preferably, a flow port is provided on the side of the flow channel away from the detection chamber, a slide rod extending into the flow port is provided on the outer wall of the baffle plate, a boss is provided on the outer wall of the slide rod, a spring is provided between the outer wall of the boss and the outer wall of the flow port, and a plug is provided on the outer wall of the slide rod away from the baffle plate.

[0011] Preferably, the outer walls of the detection chamber and the flow port are equipped with filter covers, and the outer wall of the sampling tube is equipped with a cleaning brush.

[0012] Preferably, a number of photovoltaic modules are installed on the outer wall of the base, and a battery module is installed inside the base.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention utilizes wind power for steering. In windy weather, when the wind speed sensor detects a value higher than a preset value, the motor does not operate. Instead, a wind deflector increases the wind resistance at the end of the sampling cylinder furthest from the detection chamber, causing the sampling cylinder to rotate under the influence of the wind. This makes the detection chamber face the wind direction, and the incoming airflow is blocked at the detection chamber, forming a local pressure stagnation zone. This forced stagnation of air is continuously replenished, greatly enhancing the air convection rate near the detection chamber. This, in turn, increases the airflow into the circulation channel, accelerates the air renewal rate on the surface of the carbon dioxide sensor, shortens the response time, and improves detection efficiency.

[0015] 2. This invention, through the design of the sampling cylinder and mounting frame, ensures that when the wind speed sensor detects a value lower than a preset value in windless weather, the control unit triggers the coupling mechanism and starts the motor. The motor drives the carbon dioxide sensor on the mounting frame to rotate. Simultaneously, the motor drives the pinion gear to rotate through the coupling mechanism. Under the action of the synchronous belt, the transmission gear rotates, which in turn drives the sampling cylinder to rotate around the large gear. This achieves simultaneous rotation and revolution of the carbon dioxide sensor in windless weather, increasing the sensor's detection range while disturbing the surrounding still air to create convection. This prevents the formation of a stagnant layer in still air, which could lead to low or distorted sensor readings.

[0016] 3. The present invention uses a wind deflector to create wind resistance in windy weather, causing the sampling cylinder to rotate with the wind deflector to face the wind direction. The wind force pushes the wind deflector to slide relative to the sampling cylinder, causing the wind deflector to move the plug closer to the flow port, thereby reducing the flow rate at the flow port and prolonging the residence time of the airflow in the sampling cylinder. This ensures that the airflow has sufficient contact time with the carbon dioxide sensor, guaranteeing the detection effect. Furthermore, the stronger the wind force, the greater the sliding stroke of the wind deflector after compressing the spring, bringing the plug closer to the flow port and further prolonging the outflow time of the airflow in the sampling cylinder.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] See Figures 1 to 7 As shown, a carbon monitoring device with photovoltaic solar energy storage includes a base 1, a sampling cylinder 2 rotatably connected to the outer wall of the base 1, a detection chamber 22 disposed inside the sampling cylinder 2, a mounting frame 31 rotatably connected to the detection chamber 22 via a rotating shaft, a carbon dioxide sensor 311 fixed on the mounting frame 31, a motor 3 for driving the mounting frame 31 to rotate mounted on the outer wall of the detection chamber 22, a wind speed sensor 211 and a control unit 241 disposed inside the sampling cylinder 2, the wind speed sensor 211 and the motor 3 being electrically connected via the control unit 241, a wind baffle 6 slidably connected to the outer wall of the sampling cylinder 2 on the side away from the detection chamber 22, a transmission mechanism disposed inside the sampling cylinder 2, a coupling mechanism disposed on the rotating shaft of the mounting frame 31, and the motor 3 starting the transmission mechanism via the coupling mechanism, causing the transmission mechanism to drive the sampling cylinder 2 to rotate.

[0028] The sampling cylinder 2 has a flow channel 21 that runs through the outer walls of both ends. The detection chamber 22 is located at one end of the flow channel 21 near the rotation center of the sampling cylinder 2. The sampling cylinder 2 has a transmission chamber 24. A sampling pump 212 is installed on the outer wall of the sampling cylinder 2. The sampling pump 212 is electrically connected to the wind speed sensor 211 through the control unit 241.

[0029] The transmission mechanism includes a small gear 41, a transmission gear 42, and a large gear 43 rotatably connected in the transmission chamber 24. A fixed shaft 13 is rotatably inserted into the transmission chamber 24 and mounted on the outer wall of the base 1. The large gear 43 is mounted on the fixed shaft 13 and meshes with the transmission gear 42. A synchronous belt 4 for meshing transmission is provided between the small gear 41 and the transmission gear 42. The small gear 41 is mounted on the rotating shaft of the mounting bracket 31.

[0030] It should be noted that before carbon dioxide detection, the air flow rate is detected by the wind speed sensor 211, and the control unit 241 determines whether the weather is windy or calm.

[0031] When it is windy, the wind speed sensor 211 detects a value higher than the preset value. At this time, the motor 3 does not work. The wind resistance of the sampling cylinder 2 away from the detection chamber 22 is increased by the wind baffle 6. Under the action of the wind, the sampling cylinder 2 is driven to rotate, so that the detection chamber 22 faces the wind direction. The incoming air will be blocked at the detection chamber 22, forming a local pressure stagnation zone. This forced stagnation of air will be continuously replenished, which greatly enhances the air convection rate near the detection chamber 22. This increases the airflow into the circulation channel 21, speeds up the air renewal rate on the surface of the carbon dioxide sensor 311, shortens the response time, and helps to improve detection efficiency.

[0032] In windless weather, the wind speed sensor 211 detects a value lower than the preset value. At this time, the control unit 241 triggers the coupling mechanism and starts the motor 3. The motor 3 drives the carbon dioxide sensor 311 on the mounting bracket 31 to rotate. At the same time, the motor 3 drives the pinion 41 to rotate through the coupling mechanism. Under the action of the synchronous belt 4, the transmission gear 42 rotates, which in turn drives the sampling cylinder 2 to rotate around the large gear 43. This allows the carbon dioxide sensor 311 to rotate and revolve simultaneously in windless weather, improving the sensor's detection range while disturbing the surrounding still air to form convection. This prevents the still air from forming a stagnant layer, which could lead to low or distorted sensor readings.

[0033] Furthermore, the diameter of the pinion 41 is smaller than that of the transmission gear 42, which causes the mounting bracket 31 to drive the sensor to rotate rapidly, disturbing the surrounding airflow and quickly destroying the boundary layer. The sampling cylinder 2 carries the sensor to rotate slowly, allowing the sensor sufficient time to effectively sample in each direction. The sampling pump 212 increases the airflow into the sampling cylinder 2 in windless weather, further ensuring the detection effect.

[0034] After the test is completed, the control unit 241 controls the coupling mechanism to disconnect from the main shaft of the motor 3 and then shuts down the motor 3.

[0035] Considering that the rotation of the sampling cylinder 2 may cause the connection lines of the photovoltaic module 11 to become tangled, the connection head in this invention can be a conductive slip ring or a rotary connector to avoid the wires from rotating and becoming tangled.

[0036] The coupling mechanism includes an electromagnetic clutch 33 disposed in the transmission chamber 24. The driving end of the electromagnetic clutch 33 is fixedly connected to the rotating shaft of the mounting bracket 31, and its driven end is fixedly connected to the rotating shaft of the pinion 41. The electromagnetic clutch 33 is electrically connected to the wind speed sensor 211 through the control unit 241. An encoder 32 is fixed on the inner wall of the detection chamber 22. The detection end of the encoder 32 is fixed on the main shaft of the motor 3. The encoder 32 is electrically connected to the motor 3 through the control unit 241.

[0037] It should be noted that in the initial state, the electromagnetic clutch 33 is disconnected from the main shaft of the motor 3. At this time, the sampling cylinder 2 can rotate freely and will not be affected by the main shaft of the motor 3. In windy weather, the sampling cylinder 2 rotates around the fixed shaft 13 under the action of wind force, so as to avoid driving the main shaft of the motor 3 to rotate when the motor 3 is not working, which would reduce the service life of the motor 3.

[0038] In the initial state, the motor 3 drives the sensing surface of the carbon dioxide sensor 311 to be perpendicular to the axis of the sampling cylinder 2, so that in windy weather, the airflow can directly blow onto the sensing surface of the sensor and quickly sweep across the sensing surface, which helps to improve the detection efficiency. After the detection is completed in windless weather, the control unit 241 drives the motor 3 to rotate and reset the sensor on the mounting bracket 31 by reading the encoder 32 signal.

[0039] A flow port 23 is provided on the side of the flow channel 21 away from the detection chamber 22. A slide rod 62 extending into the flow port 23 is provided on the outer wall of the baffle plate 6. A boss 621 is provided on the outer wall of the slide rod 62. A spring 61 is provided between the outer wall of the boss 621 and the outer wall of the flow port 23. A plug 63 is provided on the outer wall of the end of the slide rod 62 away from the baffle plate 6.

[0040] It should be noted that in windy weather, wind resistance is generated at the wind deflector 6, causing the sampling cylinder 2 to rotate with the wind deflector 6 to face the wind direction. The wind force pushes the wind deflector 6 to slide relative to the sampling cylinder 2, causing the wind deflector 6 to move the plug 63 closer to the flow port 23, thereby reducing the flow rate of the flow port 23, prolonging the residence time of the airflow in the sampling cylinder 2, ensuring that the airflow has sufficient contact time with the carbon dioxide sensor 311, and ensuring the detection effect. Furthermore, as the wind force increases, the sliding stroke of the wind deflector 6 after compressing the spring 61 is greater, causing the plug 63 to move closer to the flow port 23, thereby prolonging the outflow time of the airflow in the sampling cylinder 2.

[0041] The outer walls of the testing chamber 22 and the flow port 23 are equipped with filter covers 51, the outer wall of the sampling tube 2 is equipped with a cleaning brush 5, the outer wall of the base 1 is equipped with several sets of photovoltaic modules 11, and the base 1 is equipped with battery modules 12.

[0042] It should be noted that solar power is generated by several sets of photovoltaic modules 11 and the electrical energy is stored in the battery module 12 to drive the motor 3, sensor and other electrical appliances. When the sampling tube 2 rotates, the cleaning brush 5 rotates synchronously to clean the photovoltaic modules 11. The filter cover 51 prevents dust in the airflow from entering the detection chamber 22 and interfering with the sensor.

[0043] Working principle:

[0044] Before carbon dioxide detection, the air flow rate is detected by wind speed sensor 211, and the windy and windless weather is determined by control unit 241.

[0045] When it is windy, the wind speed sensor 211 detects a value higher than the preset value. The electromagnetic clutch 33 is disconnected from the main shaft of the motor 3. At this time, the motor 3 does not work. The wind resistance of the sampling cylinder 2 away from the detection chamber 22 is increased by the set wind baffle 6. Thus, the sampling cylinder 2 is driven to rotate under the action of wind, so that the detection chamber 22 faces the wind direction. The incoming air will be blocked at the detection chamber 22, forming a local pressure stagnation zone. This forced stagnation of air will be continuously replenished, which greatly enhances the air convection rate near the detection chamber 22. This increases the airflow rate into the circulation channel 21, speeds up the air renewal rate on the surface of the carbon dioxide sensor 311, shortens the response time, and helps to improve detection efficiency.

[0046] In windy weather, wind resistance is generated at the wind deflector 6, causing the sampling cylinder 2 to rotate with the wind deflector 6 to face the wind direction. The wind force pushes the wind deflector 6 to slide relative to the sampling cylinder 2, causing the wind deflector 6 to move the plug 63 closer to the flow port 23, thereby reducing the flow rate of the flow port 23, prolonging the residence time of the airflow in the sampling cylinder 2, ensuring that the airflow has sufficient contact time with the carbon dioxide sensor 311, and ensuring the detection effect. Furthermore, as the wind force increases, the sliding stroke of the wind deflector 6 after compressing the spring 61 is greater, causing the plug 63 to move closer to the flow port 23, thereby prolonging the outflow time of the airflow in the sampling cylinder 2.

[0047] In windless weather, the wind speed sensor 211 detects a value lower than the preset value. At this time, the control unit 241 triggers the coupling mechanism and starts the motor 3. The motor 3 drives the carbon dioxide sensor 311 on the mounting bracket 31 to rotate. At the same time, the motor 3 drives the pinion 41 to rotate through the coupling mechanism. Under the action of the synchronous belt 4, the transmission gear 42 rotates, which in turn drives the sampling cylinder 2 to rotate around the large gear 43. This enables the carbon dioxide sensor 311 to rotate and revolve simultaneously when there is no wind. This improves the sensor's detection range and disturbs the surrounding still air, forming convection. It also prevents the still air from forming a stagnant layer, which would cause the sensor reading to be too low or distorted.

[0048] Furthermore, the diameter of the pinion 41 is smaller than that of the transmission gear 42, which causes the mounting bracket 31 to drive the sensor to rotate rapidly, disturbing the surrounding airflow and quickly destroying the boundary layer. The sampling cylinder 2 carries the sensor to rotate slowly, allowing the sensor sufficient time to effectively sample in each direction. The sampling pump 212 increases the airflow into the sampling cylinder 2 in windless weather, further ensuring the detection effect.
