Description

Technical Field

[0001] This invention belongs to the field of carbon dust collection technology, and particularly relates to a carbon dust collection device suitable for arid environments. Background Technology

[0002] Charcoal fragments are clumps of black (brown) inorganic carbon compounds formed from the incomplete combustion of plants, serving as an effective proxy for fire. Based on particle size, charcoal fragments can be divided into large charcoal / charcoal and microcharcoal, with a dividing line around ~200 μm. Under natural conditions, large charcoal fragments (particle size >200 μm) are transported shorter distances and typically remain at the combustion site, reflecting ignition information near the fire's origin. Microcharcoal fragments (particle size between ~10-200 μm) are transported to locations relatively far from the ignition point, reflecting fire information over a larger area. In the field of climate / environmental change, microcharcoal fragments have attracted significant attention due to their ease of preservation, wide distribution, and accessibility. In recent decades, researchers have used changes in the size, morphology, and concentration / flux of charcoal fragments in soil, ice cores, loess, and lakes to reconstruct the extent, intensity, or frequency of fire activity at different temporal and spatial scales. However, further research has revealed inconsistencies in charcoal fragment changes recorded in sediments at different locations within the same watershed (especially in arid regions), increasing the difficulty of further data comparison and integration. Therefore, studying the propagation and deposition processes of carbonaceous debris under complex basin-mountain terrain conditions in arid regions is an important way to solve the above problems. Wind is one of the main driving forces for carbonaceous debris transport, but to date, research on wind-borne micro-carbonaceous debris is still in its preliminary stage, and no research on wind-transported collection devices has been reported in China. The only existing air particulate matter collection devices suitable for arid regions, ZL202020242742.6 and ZL202111042908.5, are mainly used for pollen collection. Due to the significant differences between carbonaceous debris and pollen / aerosols in terms of particle size, structural composition, density, and transport mode, these collection devices are not suitable for collecting micro-carbonaceous debris and cannot achieve large-scale, high-efficiency collection. Therefore, there is an urgent need for an automated collection device for airborne micro-carbonaceous debris under arid climatic conditions. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that the existing technology is not suitable for the collection of micro-carbon particles and cannot achieve large-scale, high-efficiency collection.

[0004] A carbon dust particle collection device suitable for arid environments includes a collection bucket I, a collection bucket support, multiple collection buckets II, a motor, and a collection bucket rotation motor; An air inlet is provided on the outer wall of the collection tank I. Through holes are symmetrically provided at the top and bottom ends of the collection tank I. The central shaft passes through the two through holes of the collection tank I and is fixedly connected to the collection tank I. The bottom end of the central shaft is rotatably connected to the support bracket. A central shaft gear is installed on the central shaft. The central shaft gear is located inside the collection tank I and above the bottom through hole. The motor is fixedly installed inside the bottom end of the collection tank I. The output end of the motor is equipped with a bracket rotating motor gear, which meshes with the central shaft gear. The central shaft is rotatably connected to the collection tank bracket via bearings. A bracket fixing gear is installed at the bottom of the collection tank bracket. Collection tank II is installed on the collection tank bracket. A collection tank rotary motor is installed on the inner side wall of collection tank I. A motor gear is installed on the output shaft of the collection tank rotary motor, and the motor gear meshes with the bracket fixing gear.

[0005] Furthermore, a lower bearing 43 and an upper bearing 44 are installed on the central shaft 421, both of which are located inside the collection bucket I4.

[0006] Furthermore, the collection bucket support is circular and located inside the collection bucket.

[0007] Furthermore, the collection bucket support is provided with several support plates distributed circumferentially around the central axis, and a collection bucket II is fixedly installed on each support plate of the collection bucket support.

[0008] Furthermore, the collection bucket II includes an upper collection bucket and a lower collection bucket, which are fixedly connected. A filter screen is installed at the top of the upper collection bucket, a vibration cleaning device is fixedly installed on the side wall of the upper collection bucket, and an air inlet is installed on the side wall of the upper collection bucket, which is connected to the air inlet. A conical collection cavity is installed inside the lower collection bucket, and anti-freezing and cracking material is filled between the lower collection bucket and the conical collection cavity.

[0009] Furthermore, the vibration cleaning device includes a cleaning device base, a dual-head motor, and an eccentric counterweight; the cleaning device base is fixedly installed on the outer side wall of the upper part of the collection bucket, the dual-head motor is fixedly installed on the cleaning device base, and the two output ends of the dual-head motor are respectively fixedly installed with eccentric counterweights.

[0010] Furthermore, it also includes an electric latch, which is fixedly installed on the inner wall of collection tank I and located above the air inlet.

[0011] Furthermore, the electric latch includes a drive motor, a latch rod, and a mounting base. The mounting base is fixedly installed on the inner side wall of the collection tank I, the latch rod is slidably connected to the mounting base, and the output shaft of the drive motor is connected to the latch rod.

[0012] Furthermore, it also includes a solar power panel, a wind direction angle detector, and a wind vane; the solar power panel is fixedly installed at the top of the central axis; the top of the collection tank I is equipped with a wind direction angle detector and a wind vane, and the wind direction angle detector and the wind vane are symmetrically arranged.

[0013] Furthermore, it also includes a controller, which is electrically connected to the solar power panel, wind direction angle detector, wind vane, motor, drive motor of electric plug, and rotating motor of collection bucket.

[0014] The beneficial effects of this invention are as follows: 1. Traditional collectors mainly involve placing a filter coated with silicone oil in the air, relying on its adhesiveness to collect the target particles. However, in arid regions with extreme drought and strong winds, the silicone oil dries quickly. Furthermore, the exposed ground and high levels of sand in arid areas cause the traditional filter to become saturated with dust rapidly. This invention overcomes these shortcomings and significantly increases collection efficiency.

[0015] 2. This design allows for flexible setting of the start time and number of collection segments for each collection bucket, which is particularly important for research on timed collection at large spatial scales. In addition to ensuring the synchronous collection of particulate matter at different locations at specified time intervals, it saves a lot of manpower and resources.

[0016] 3. This design incorporates a wind direction angle detection device at the main rotating shaft, which can acquire the windward angle and wind direction changes of the collection frame in real time and feed the detection signal back to the controller. This structure allows the device to move beyond passive orientation by relying solely on the tail fin, enabling real-time judgment of the matching degree between the air inlet and the incoming wind direction. This allows for automatic optimization of sampling timing and bucket changing processes when wind direction changes frequently or wind conditions are unstable, improving the accuracy of micro-carbon particle collection and the reliability of continuous unattended operation under complex wind conditions in arid regions.

[0017] 4. This design takes into account the risk of the collection tank freezing and cracking due to condensation under extreme low temperatures in arid winters. The collection tank adopts a double-layer design and adds insulation material to minimize the possibility of damage to the device. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to Figures 1-4 A carbon dust particle collection device suitable for arid environments includes: a solar power panel 1, a wind direction angle detector 2, a wind vane 3, a collection bucket I 4, a collection bucket II 5, a motor 6, a collection bucket support 7, an electric latch 8, and a collection bucket rotation motor 9.

[0023] An air inlet 41 is provided on the outer wall of the collection bucket I4. Both the upper and lower ends of the collection bucket I4 have through holes for mounting a central shaft 421, and the two through holes are symmetrically arranged. The central shaft 421 passes through the two through holes of the collection bucket I4 and is fixedly connected to the collection bucket I4. The bottom end of the central shaft 421 is rotatably connected to the support bracket 42. A central shaft gear 4211 and a lower bearing 43 are mounted on the central shaft 421, both located inside the collection bucket I4, above the bottom through hole, with the lower bearing 43 located below the central shaft gear 4211. An upper bearing 44 is mounted on the central shaft 421, located inside the collection bucket I4 and below the top through hole. The central shaft also has a lower bearing 43 and an upper bearing 44, both located inside the collection bucket I4, which serve to reduce rotational friction and ensure the stability of the relative position of the central shaft 421 and the collection bucket I4. A motor 6 is fixedly installed at the bottom of the inside of the collection bucket I4. A bracket rotating motor gear 61 is installed at the output end of the motor 6. The bracket rotating motor gear 61 meshes with the central shaft gear 4211.

[0024] When motor 6 starts, its output shaft drives the bracket rotating motor gear 61 to rotate, which in turn drives the central shaft gear 4211 to rotate. Since the central shaft gear 4211 is fixedly mounted on the central shaft 421, the central shaft 421 rotates accordingly. Because the central shaft 421 is fixedly connected to the collection bucket I4, the rotation of the central shaft causes the entire collection bucket I4 to rotate synchronously. The bottom end of the central shaft 421 is only rotatably connected to the support bracket 42. Therefore, the entire collection bucket I4 and the central shaft assembly rotate around the support point of the support bracket 42, realizing the rotational movement of the entire collection bucket I4 around the central shaft 421. In this application, motor 6 and bracket rotating motor gear 61 are fixed to the bottom inside the collection bucket I4, and they rotate together with the collection bucket; while the central shaft gear 4211 is fixedly mounted on the central shaft 421 and does not move with the revolution of the bracket rotating motor gear 61. The meshing relationship between the two remains stable during the rotation of the bucket. In addition, the bottom end of the central shaft 421 is rotatably connected to the support bracket 42 to ensure that the barrel does not detach from the support during rotation, and the lower bearing 43 and the upper bearing 44 reduce the frictional loss between the central shaft 421 and the through hole of the collection barrel I4, ensuring transmission efficiency and rotational stability.

[0025] The central shaft 421 is rotatably connected to the collection bucket support 7 via bearings, and a support fixing gear 71 is installed at the bottom of the collection bucket support 7. The collection bucket support 7 is circular and located inside the collection bucket I4. Several support plates are arranged circumferentially around the central shaft 421 on the collection bucket support 7; in this embodiment, there are 12 support plates. A collection bucket II5 is fixedly installed on each support plate of the collection bucket support 7. The inner wall of the collection bucket I4 is fixedly connected to the collection bucket rotary motor 9 via a connecting plate. A motor gear is installed on the output shaft of the collection bucket rotary motor 9, and the motor gear meshes with the support fixing gear 71.

[0026] When the collection bucket rotation motor 9 starts, its output shaft drives the motor gear to rotate around its own axis. Since the motor 9 is fixed to the inner wall of the stationary collection bucket I4, the rotation of the motor gear is purely self-rotation. The motor gear meshes with the bracket fixing gear 71. Since the bracket fixing gear 71 is fixed to the collection bucket bracket 7, and the collection bucket bracket 7 is rotatably connected to the central shaft 421 through bearings, the rotation of the motor gear drives the bracket fixing gear 71 to rotate around the central shaft 421. The rotation of the bracket fixing gear 71 drives the entire collection bucket bracket 7 to rotate around the central shaft 421, thereby causing all the collection buckets II5 fixedly mounted on the bracket support plate to perform circular motion around the central shaft 421.

[0027] Please refer to Figure 5 The collection bucket II5 includes an upper part 51 and a lower part 52, which are fixedly connected. A filter screen 511 is installed at the opening of the upper part 51, and a vibration cleaning device 512 is fixedly installed on the side wall of the upper part 51, located below the filter screen 511. An air inlet 513 is installed on the side wall of the upper part 51, connected to an air inlet 41. A pin opening 53 is installed on the side wall of the upper part 51, located above the air inlet 513. A cyclone separation chamber 521 is installed inside the lower part 52, and the top of the cyclone separation chamber 521 is fixedly connected to the bottom of the upper part 51. Anti-freezing and crack-resistant material 522 is filled between the lower part 52 and the cyclone separation chamber 521.

[0028] Please refer to Figure 6The vibration cleaning device 512 includes a cleaner base 5121, a dual-head motor 5122, and eccentric counterweights 5123. The cleaner base 5121 is fixedly installed on the outer wall of the upper part 51 of the collection bucket, and the dual-head motor 5122 is fixedly installed on the cleaner base 5121. Eccentric counterweights 5123 are fixedly installed on the two output ends of the dual-head motor 5122. After the dual-head motor 5122 starts, it drives the two eccentric counterweights 5123 to rotate. The rotation of the eccentric counterweights 5123 generates a periodically changing centrifugal force, causing the dual-head motor 5122 and the cleaner base 5121 to vibrate. The vibration is transmitted sequentially through the cleaner base 5121 and the side wall of the upper part 51 of the collection bucket to the filter screen 511, causing the filter screen 511 to vibrate, shaking off carbon particles and impurities adhering to the filter screen, reducing filter screen clogging and maintaining the filter screen's air permeability.

[0029] The electric latch 8 is fixedly installed on the inner wall of the collection tank I4, and located above the air inlet 41. The electric latch 8 includes a drive motor (not shown in the figure), a latch rod 801, and a mounting base 802. The mounting base 802 is fixedly installed on the inner wall of the collection tank I4, and the latch rod 801 is slidably connected to the mounting base 802. The output shaft of the drive motor is connected to the latch rod 801 and is used to drive the latch rod 801 to extend or retract.

[0030] The pin 801 can extend or retract under the drive of the drive unit, and the pin 801 corresponds to the pin opening 53 on the collection bucket II 5 that has rotated to the sampling position. When the collection bucket II 5 rotates to the sampling position, the controller controls the drive unit to extend the pin and insert it into the pin opening 53, thereby restricting the collection bucket support 7 from continuing to rotate and achieving positioning and locking. When the preset sampling time is reached, the controller controls the pin of the electric pin 8 to retract and exit the pin opening 53, and then controls the collection bucket rotation motor 9 to start, so that the next collection bucket II 5 rotates to the sampling position.

[0031] The solar power panel 1 is fixedly installed at the top of the central shaft 421 for power supply.

[0032] The top of the collection bucket I4 is equipped with a wind direction angle detector 2 and a wind vane 3, and the wind direction angle detector 2 and the wind vane 3 are symmetrically arranged.

[0033] Please refer to Figure 7 The controller is electrically connected to the solar power panel 1, the wind direction angle detector 2, the wind vane 3, the motor 6, the drive motor of the electric plug 8, and the collection bucket rotation motor 9.

[0034] In this application, the rotation of I4 is to align the air inlet with the direction of the incoming wind, and the rotation of collection bin II5 is set according to a timer. Once collection bin II5 is full, the next collection bin II5 is replaced. Collecting carbon dust requires aligning it with the direction of the incoming wind, and the design of 12 collection bins II5 allows for long-term unattended collection.

[0035] How this application works: When this device is in operation, the solar power panel 1 supplies power to the controller, motor 6, electric latch 8, and collection bucket rotation motor 9. The wind direction angle detector 2 detects changes in the device's angle relative to the wind direction and transmits the detection signal to the controller. Based on the feedback signal from the wind direction angle detector 2, the controller controls the motor 6 to operate, causing the bracket rotation motor gear 61 to move along the central shaft gear 4211, driving the collection bucket I4 to rotate around the central shaft 421, thereby adjusting the air inlet 41 to face the wind direction. The wind vane 3 is located on the top of the device to assist in determining or stabilizing the windward direction.

[0036] Once the air inlet 41 is in position, the controller starts the collection bucket rotation motor 9. The collection bucket rotation motor 9, through its output drive gear meshing with the internal gear 71, drives the collection bucket support 7 to rotate, causing one of the collection buckets II5 to rotate to the sampling position. At this time, the collection bucket air inlet 513 on collection bucket II5 is connected to the corresponding air inlet 41 of collection bucket I4, and the locking structure 8 is inserted into the pin hole 53 to lock the current collection bucket II5 in position. External airflow containing carbon particles enters collection bucket II5 through air inlet 41 and collection bucket air inlet 513. Under the action of centrifugal force and gravity, the carbon particles settle to the bottom of the cyclone separation chamber 521, while the airflow is discharged through the top filter outlet 511.

[0037] During the sampling process, the vibration cleaning device 512 is intermittently activated according to a preset program. The internal vibration motor drives the eccentric vibrating block to rotate and generate periodic vibration. The resulting vibration force is transmitted to the filter screen outlet 511 through the mounting base of the vibration cleaning device 512 and the upper part 51 of the collection bucket, causing the filter screen to vibrate and shake off the carbon particles and impurities attached to the filter screen, reducing filter screen clogging. When the preset sampling time is reached, the controller first controls the electric latch 8 to disengage from the latch port 53, and then the collection bucket rotation motor 9 drives the collection bucket support 7 to rotate, so that the next collection bucket II5 rotates to the sampling position, and the electric latch 8 cooperates with the corresponding latch port 53 to complete the positioning, thereby realizing continuous automatic sampling of multiple collection buckets II5.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
