Description

Technical Field

[0001] The present application relates to the field of environmental measurement technology, and in particular to an online environmental monitoring system. Background Art

[0002] In the field of environmental monitoring, especially for monitoring sand and gravel in wind and sand flows, wind erosion equipment is one of the important tools. Traditional wind erosion equipment usually includes a simple sand inlet channel and a collection device, but these devices have many problems in actual use. For example, in some natural environments, the sand inlet channel often faces a large temperature difference. When warm and humid air flows into the sand inlet channel with a lower temperature, water vapor easily condenses into dew.

[0003] Condensed dew will cause the gravel to adhere to the inner wall of the channel. This adhesion phenomenon will cause the weight of the gravel in the sand inlet channel to not meet the ideal sand content of the gravel entering the air inlet channel, thereby making the measured wind and sand data inaccurate. Moreover, after the bonded gravel falls off naturally, it will increase the weight of the gravel obtained in the next time period, affecting the gravel weight detection. Summary of the invention

[0023] In summary, this application mainly has the following beneficial effects:

[0024] The ambient airflow enters the feed box and is divided into an upper air inlet channel and a lower air inlet channel due to the presence of a partition. A fixed dust removal cloth is provided at the entrance of the upper air inlet channel. When the airflow passes through, the dust removal cloth filters out sand and impurities, making the airflow entering the upper air inlet channel relatively pure. A movable dust removal cloth is provided at the entrance of the lower air inlet channel. When measuring, the lower air inlet channel is opened, and when not measuring, the air inlet channel can be closed.

[0025] During operation, the dust removal cloth at the entrance of the lower air inlet channel is opened, and the sand and gravel carried by the wind and sand flow enters the lower air inlet channel and moves in the channel until it reaches the collecting mechanism. After the collecting mechanism collects the sand and gravel, the sand scraping mechanism is activated to scrape out the sand and gravel on the inner wall of the lower air inlet channel, and the collecting mechanism is controlled to dry the sand and gravel in the collecting mechanism, that is, the collecting mechanism is driven to move upward to the upper air inlet channel. At this time, the relatively dry airflow in the upper air inlet channel can dry the sand and gravel in the collecting mechanism.

[0026] The collecting mechanism collects the gravel fully or moves to the top of the metering device after a period of drying. The metering device receives the gravel released by the collecting mechanism, and the weighing sensor at the bottom senses the weight change, thereby obtaining the weight information of the gravel in the wind and sand flow, providing data support for analyzing the movement law and erosion capacity of the wind and sand.

[0027] By dividing the ambient airflow into the upper air inlet channel and the lower air inlet channel, and setting dust removal cloths at the entrance of each channel. After the collecting mechanism collects the sand and gravel, the sand scraping mechanism is used to clean the sand and gravel adhering to the inner wall of the lower air inlet channel, and then the collecting mechanism is moved to the upper air inlet channel for drying. This can ensure to the greatest extent that the weight of the sand and gravel that finally enters the metering device truly reflects the actual situation of the sand and gravel in the wind and sand flow, thereby providing a reliable data basis for accurately analyzing the movement law and erosion capacity of wind and sand, and making the measured sand and gravel weight information more accurate.

[0028] The removable dust-removing cloth at the entrance of the lower air inlet channel can close the air inlet channel when no measurement is being performed, preventing foreign debris from entering the channel at will and causing the sand and gravel to mix together and produce weight when dried. At the same time, the sand scraping mechanism can promptly scrape out and clean the sand and gravel adhering to the inner wall of the lower air inlet channel. The removable dust-removing cloth allows the lower air inlet channel to be flexibly opened and closed according to measurement requirements. When measurement is required, the channel is opened to allow the sand flow to enter, and when no measurement is performed, the channel is closed to prevent debris from entering. The dual-channel design improves the drying speed.

[0047] refer to Figure 1-Figure 5 , an environmental online monitoring system, comprising:

[0048] The feed box 10 is provided with a partition 101 inside, which divides the feed box 10 into an upper air inlet channel 102 and a lower air inlet channel 103. A fixed dust cloth 20 is provided at the entrance of the upper air inlet channel 102, and a movable dust cloth 20 is provided at the entrance of the lower air inlet channel 103, which is used to close the lower air inlet channel 103. The feed box 10 is provided with openings on one side relative to the upper air inlet channel 102 and the lower air inlet channel 103, and the openings are closed with dust cloths 20 to allow airflow;

[0049] The receiving mechanism 30 is arranged at the rear of the lower air inlet channel 103 and is used to receive the sand and gravel entering from the lower air inlet channel 103;

[0050] The sand scraping mechanism 40 is disposed in the lower air inlet channel 103 and is used to scrape out the sand and gravel adhered to the inner wall of the lower air inlet channel 103 and push it back into the material recovery mechanism 30;

[0051] A metering device, disposed below the receiving mechanism 30, for receiving and weighing the sand and gravel released by the receiving mechanism 30;

[0052] The receiving mechanism 30 is further configured to receive the sand and gravel and then move them to the upper air inlet channel 102 for drying.

[0053] The ambient airflow enters the feed box 10, and the partition 101 forms an upper air inlet channel 102 and a lower air inlet channel 103. The dust removal cloth 20 is fixed at the entrance of the upper air inlet channel 102 to filter the airflow, and the dust removal cloth 20 is movable at the entrance of the lower air inlet channel 103 to open and close the channel. When measuring, the lower air inlet channel 103 is opened, and the wind and sand flow carries sand and gravel into the channel and reaches the material collection mechanism 30 through the channel. After collecting the material, the sand scraping mechanism 40 cleans the sand and gravel that may be adhered to the inner wall of the lower air inlet channel 103, and then the material collection mechanism 30 moves to the upper air inlet channel 102 for drying, and finally moves to the top of the metering device to release the sand and gravel, which is measured by the weighing sensor.

[0054] The measuring device can be set to continuously weigh and measure, and after the first measurement, cumulative monitoring can be performed on this basis. It is also possible to set multiple measuring devices, and after each measurement, switch to a new measuring device for measurement.

[0055] The dual-channel and dust-removing cloth 20 design ensures that no sand or gravel enters during drying. The scraping and drying process ensures that the weight of the sand or gravel accurately reflects the actual situation of the wind and sand flow, thereby improving measurement accuracy. The movable dust-removing cloth 20 flexibly controls the opening and closing of the lower air inlet channel 103 to avoid the influence of debris during non-measurement periods, and scrapes the sand and gravel on the inner wall to effectively eliminate the weight error factor caused by the adhesion of sand and gravel, thereby improving data reliability, ensuring that the measured sand and gravel weight data is not interfered by the sand and gravel attached to the inner wall of the channel, and accurately obtaining the true weight information of the sand and gravel in the wind and sand flow.

[0056] In some embodiments, the material receiving mechanism 30 includes a material receiving member 301, a material receiving driving device, and a rotating driving device 302. The material receiving member 301 is a rectangular box structure. The side of the material receiving member 301 facing the lower air inlet channel 103 is an open opening. A side wall of the material receiving member 301 opposite to the open opening, the top wall and the bottom wall of the material receiving member 301 are all closed and connected by the dust removal cloth 20.

[0057] The metering device is arranged below the receiving member 301, and the dust-removing cloths 20 at the top and bottom of the receiving member 301 are driven and connected by the rotating driving device 302, so that the dust-removing cloths 20 at the top and bottom of the receiving member 301 can rotate;

[0058] The material receiving driving device is connected to the top of the side wall of the material receiving piece 301, and can drive the material receiving piece 301 to move upward into the upper air inlet channel 102, move downward into the lower air inlet channel 103, and continue to move downward from the lower air inlet channel 103 to the bottom of the lower air inlet channel 103.

[0059] The material receiving drive device includes a material receiving drive motor, which is arranged on the inner top wall of the upper air inlet channel 102. The rotation drive device 302 includes a rotation drive motor 303, a rotation drive gear and a rotating shaft. The rotation drive motor 303 is connected to the material receiving part 301. The rotation drive motor 303 drives the rotating shaft to rotate through the rotation drive gear. The rotating shaft is connected to the frame arranged outside the dust removal cloth 20, and the rotating shaft drives the dust removal cloth 20 to rotate downward.

[0060] The core component of the material receiving mechanism 30 is a material receiving piece 301 of a rectangular box structure, one side of which is set as an open mouth, and the open mouth is directly opposite to the lower air inlet channel 103, so as to realize the effective collection of sand and gravel in the wind and sand flow. The remaining side walls of the material receiving piece 301 except the open mouth, that is, the side wall, top wall and bottom wall relative to the open mouth are closed and connected by means of a dust-removing cloth 20. It should be noted that the corresponding tail of the feed box 10 is also set as a dust-removing cloth 20 closed structure, which allows the gas in the upper and lower air inlet channels 103 to flow smoothly. During the operation of the device, when the material receiving operation is required, the wind and sand gravel in the lower air inlet channel 103 can smoothly pass through the open mouth into the interior of the material receiving piece 301 under the action of wind. At this time, the unbonded gravel will be stored at the bottom of the material receiving piece 301. When the receiving part 301 has finished receiving the materials and needs to be scraped out, the receiving drive device drives the receiving part 301 to move downward, so that the receiving drive device moves to the lower side of the lower air inlet channel 103 and is close to the outlet, so that the sand can be scraped out by the sand scraping mechanism 40 and just fall on the top surface of the receiving part 301. After the sand is scraped out, the receiving part 301 moves upward into the upper air inlet channel 102. At this time, the wet sand and dry sand exist in the upper and lower layers of the receiving part 301. When scraping sand, the entrance of the lower air inlet channel 103 is closed. The upper and lower air inlet channels 103 can only be blown by airflow to increase the drying effect. After drying, the dust removal cloth 20 at the top and bottom of the receiving part 301 driven by the rotating drive device 302 is rotated. The rotation drive device 302 is composed of a rotation drive motor 303, a rotation drive gear and a rotating shaft. The rotation drive motor 303 is installed on the receiving member 301. Its power output is transmitted to the rotating shaft through the rotation drive gear. The rotating shaft is connected to the frame provided on the outside of the dust removal cloth 20, thereby driving the dust removal cloth 20 to rotate downward. The metering device is provided below the receiving member 301. The two correspond to each other in the vertical direction. After the dust removal cloth 20 rotates downward, the receiving member 301 releases the gravel, which is directly received and processed by the metering device.

[0061] The rectangular box-structured material collecting member 301 of the material collecting mechanism 30 and the specific opening and closing connection design can effectively collect sand and gravel in the wind and sand flow, and its movement at different positions can cooperate with the sand scraping mechanism 40 and the drying process. The material collecting drive device can accurately control the movement of the material collecting member 301 in the upper and lower air inlet channels 103 and under the channels to achieve efficient connection of material collecting, sand scraping and drying operations, ensure the smooth operation of the entire monitoring device and the accuracy of sand and gravel processing, enable the device to effectively respond to work requirements at different stages, and improve overall monitoring efficiency and data reliability.

[0062] This layout and driving mode of the material receiving drive device can stably and accurately control the movement of the material receiving member 301, ensure its position accuracy under different working conditions, and improve the reliability and stability of the operation of the entire material receiving mechanism 30. The rotating drive device 302 effectively solves the problem of controlling the release of sand and gravel in the material receiving member 301 to the metering device, so that the sand and gravel can enter the metering device in an orderly manner for weighing, ensuring the accuracy and repeatability of the weighing data, which is conducive to obtaining accurate information on the weight of sand and gravel in the wind and sand flow, and improving the monitoring accuracy of the entire environmental online monitoring system.

[0063] In some embodiments, the metering device includes a weighing sensor, a carrying tray, a signal conditioning circuit and a protective shell. The bottom of the carrying tray is connected to the weighing sensor, the weighing sensor is connected to the signal conditioning circuit, the weighing sensor and the carrying tray are arranged in the protective shell, the top of the protective shell has an opening and is connected to the lower air inlet channel 103, and the material receiving piece 301 can be moved into the protective shell.

[0064] When the metering device is working, the carrying tray is used to receive the gravel released by the receiving mechanism 30, and the weighing sensor at the bottom senses the weight change of the gravel on the carrying tray and transmits the weight signal to the signal conditioning circuit for processing, and the signal conditioning circuit is used to amplify the signal. The protective shell plays a role in protecting the weighing sensor and the carrying tray, and its top opening is connected to the lower air inlet channel 103, so that the receiving part 301 can move smoothly into the protective shell, so that the gravel released by the receiving part 301 can accurately fall on the carrying tray for weighing, and at the same time provide space for its movement.

[0065] The metering device can accurately measure the weight of the sand and gravel released by the material receiving mechanism 30 through the weighing sensor and signal conditioning circuit, providing accurate data support for analyzing the movement law and erosion capacity of wind and sand. The design of the protective shell protects the internal weighing components from external environmental interference, ensuring the accuracy and stability of weighing; on the other hand, its connection structure with the lower air inlet channel 103 ensures the effective connection between the material receiving component 301 and the carrying tray, so that the entire weighing process can proceed smoothly, improving the reliability and practicality of the metering device, and helping to improve the overall performance of the online environmental monitoring system.

[0066] In some embodiments, the scraping mechanism 40 includes a scraping drive motor 401, a scraping extension rod 402, a scraping strip 403 and an offset mechanism 404. The scraping drive motor 401 is connected to the outer wall of the feed box 10, and the driving end of the scraping drive motor 401 extends into the feed box 10. The scraping extension rod 402 is connected to the driving end of the scraping drive motor 401 and can extend into the entrance of the lower air inlet channel 103. The scraping strip 403 is connected to the scraping extension rod 402, and the scraping strip 403 is vertically connected to the scraping extension rod 402. The scraping strip 403 is arranged along the width direction of the lower air inlet channel 103, and the scraping strip 403 is in close contact with the partition 101 when scraping sand.

[0067] The offset mechanism 404 is disposed in the upper air inlet channel 102. The offset mechanism 404 is configured to abut the scraping strip 403 downward when the scraping strip 403 moves toward the entrance of the lower air inlet channel 103, so that the scraping strip 403 moves downward after being offset a predetermined distance from the partition 101. When the scraping strip 403 arrives at the entrance of the lower air inlet channel 103, the offset mechanism 404 is reset, and the scraping strip 403 abuts against the partition 101, wherein the scraping extension rod 402 includes an elastic member.

[0068] When the scraping mechanism 40 is working, the scraping drive motor 401 is connected to the outer wall of the feed box 10, and its driving end extends into the feed box 10 to drive the scraping extension rod 402 to move. The scraping bar 403 is connected to the scraping extension rod 402. When the scraping extension rod 402 extends into the entrance of the lower air inlet channel 103, the scraping bar 403 scrapes out the gravel adhered to the inner wall of the lower air inlet channel 103. When the scraping strip 403 moves toward the entrance, the offset mechanism 404 drives the offset driving sheet 406 to abut against the scraping strip 403 downward through the offset motor 405, so that the scraping strip 403 moves after being offset downward by a predetermined distance from the partition 101, so as to prevent the scraping strip 403 from scraping out the gravel when extending toward the entrance of the downward air inlet channel 103, causing the scraping strip 403 to throw the gravel toward the entrance when it approaches the entrance, causing the gravel to accumulate at the entrance or fall into the gap of the entrance structure, causing data distortion. When the scraping strip 403 arrives at the entrance, the offset mechanism 404 is reset, and the scraping strip 403 abuts against the partition 101 for scraping. With such a configuration, it is possible to prevent the gravel from being thrown out of the entrance driven by the scraping strip 403.

[0069] The sand scraping mechanism 40 can effectively clean the sand and gravel adhered to the inner wall of the lower air inlet channel 103, thereby ensuring the accuracy of the weight detection of the sand and gravel in the channel and reducing the weight error caused by the adhered sand and gravel.

[0070] The offset mechanism 404 includes an offset motor 405 and an offset driving plate 406 . The offset driving plate 406 is connected to the offset motor 405 and arranged in parallel along the length direction of the partition 101 . The offset motor 405 drives the offset driving plate 406 to abut against the scraping strip 403 .

[0071] The elastic member can be a metal elastic member with good elastic restoring performance. When it abuts against the metal elastic member, the sand scraping extension rod 402 can be bent downward away from the partition 101. Without alignment and squeezing, the sand scraping strip 403 can be closely attached to the partition 101 to scrape out the gravel.

[0072] The offset motor 405 of the offset mechanism 404 drives the offset drive plate 406 to move. Since the offset drive plate 406 is arranged in parallel along the length direction of the partition 101, when the scraping strip 403 moves, the offset motor 405 can drive the offset drive plate 406 to abut against the scraping strip 403 according to the position of the scraping strip 403, thereby realizing the downward offset control of the scraping strip 403.

[0073] The offset mechanism 404 includes multiple offset mechanisms 404, which are respectively arranged on the top wall, both side walls and the bottom surface of the lower air inlet channel 103. The offset mechanism 404 is configured to drive the offset mechanism 404 located in the lower air inlet channel 103 to move to the entrance of the lower air inlet channel 103 to scrape out the gravel on the top wall of the lower air inlet channel 103. After resetting, the offset mechanisms 404 on both side walls of the lower air inlet channel 103 are controlled to move to the entrance of the lower air inlet channel 103 to scrape out the gravel on both side walls of the lower air inlet channel 103. After resetting, the offset mechanism 404 at the bottom of the lower air inlet channel 103 is controlled to move to the entrance of the lower air inlet channel 103 to scrape out the gravel on the bottom of the lower air inlet channel 103. The offset mechanism 404 arranged on the top wall of the lower air inlet channel 103 is connected to the partition 101, and the offset mechanism 404 arranged on both side walls and the bottom surface of the lower air inlet channel 103 is connected to the outside of the feed box 10.

[0074] The offset motor 405 is connected to the partition 101 , and the offset driving plate 406 is set in the gap between the partition 101 and the feed box 10 . The offset driving plate 406 is arranged in parallel along the length direction of the partition 101 . The offset motor 405 drives the offset driving plate 406 downward to abut against the scraping strip 403 .

[0075] Multiple offset mechanisms 404 are respectively arranged on the top wall, the side walls and the bottom surface of the lower air inlet channel 103. When working, the offset mechanism 404 located on the top wall of the lower air inlet channel 103 is first controlled to move to the entrance to scrape the gravel on the top wall. After resetting, the offset mechanisms 404 on the side walls are controlled to move to the entrance to scrape the gravel on the side walls. Finally, the offset mechanism 404 at the bottom is controlled to move to the entrance to scrape the gravel on the bottom. The offset mechanisms 404 at different positions cooperate with each other to orderly complete the sand scraping operation on each surface of the inner wall of the lower air inlet channel 103.

[0076] The setting of this multi-position offset mechanism 404 can completely and thoroughly clean the grit bonded to each surface of the inner wall of the lower air inlet channel 103, ensuring that there is no residual grit in the channel that affects the grit weight detection, further improving the accuracy and reliability of the grit weight detection. The orderly operation of each position offset mechanism 404 makes the entire sand scraping process more efficient and orderly, improves the working efficiency and data quality of the online environmental monitoring system, and provides a stronger guarantee for the accurate analysis of the movement law and erosion capacity of wind and sand. Driving them separately at the same time can avoid interference.

[0077] The offset motor 405 is connected to the partition 101, and the offset drive plate 406 is set in the gap between the partition 101 and the feed box 10. When the offset motor 405 is working, the offset drive plate 406 is driven downward to abut the scraping bar 403, thereby realizing the position control of the scraping bar 403. Due to the compact structure of this layout, the internal space of the feed box 10 can be effectively utilized, and it is convenient to accurately control the movement of the scraping bar 403.

[0078] Its compact structural design saves internal space of the feed box 10, is conducive to the optimized layout of the internal structure of the entire environmental online monitoring system, improves the utilization rate of the internal space of the device, makes the overall structure of the device more compact and reasonable, and also facilitates the installation, maintenance and commissioning of the equipment, reducing the manufacturing cost and operation and maintenance cost of the equipment.

[0079] In some embodiments, a closed driving mechanism is also included for driving the dust cloth 20 at the entrance of the lower air inlet channel 103 to move. The closed driving mechanism includes a closed driving motor 50, which is arranged on the outside of the feed box 10. The dust cloth 20 at the entrance of the lower air inlet channel 103 is externally connected with a connecting frame. The driving end of the closed driving motor 50 is connected to the connecting frame to drive the dust cloth 20 to open and close the entrance of the lower air inlet channel 103.

[0080] The closed driving mechanism works through a closed driving motor 50 arranged on the outside of the feed box 10, and its driving end is connected to the connecting frame of the dust cloth 20 at the entrance of the lower air inlet channel 103. When it is necessary to close the entrance of the lower air inlet channel 103, the closed driving motor 50 drives the connecting frame to drive the dust cloth 20 to move, thereby achieving the closure of the entrance; when it is necessary to open the entrance for measurement, the closed driving motor 50 drives in reverse to move the dust cloth 20 away, and the wind and sand flow can enter the lower air inlet channel 103.

[0081] The closed drive mechanism can flexibly control the opening and closing of the dust removal cloth 20 at the entrance of the lower air inlet channel 103, effectively close the channel when not measuring, and prevent foreign debris from entering the channel at will to affect the sand weight detection, thereby ensuring the accuracy and reliability of the measurement data. During measurement, the channel can be opened in time to allow the wind and sand flow to enter smoothly, ensuring that the monitoring device can work normally, improving the practicability and adaptability of the device, and facilitating accurate wind and sand flow monitoring under different environmental conditions.

[0082] In some embodiments, it also includes a column 60 and a spoiler 70. Any of the above-mentioned online environmental monitoring systems is rotatably connected to the column 60 through a swivel. The spoiler 70 is connected to the swivel to control the direction of any of the above-mentioned online environmental monitoring systems to face the wind direction. Any of the above-mentioned online environmental monitoring systems includes multiple ones, which are arranged at different heights in the vertical direction.

[0083] The online environment monitoring system is rotatably connected to the column 60 through a swivel, and the spoiler 70 is connected to the swivel. The spoiler 70 can sense the change in wind direction and drive the entire online environment monitoring system to rotate through the swivel, so that the direction of the device can face the wind direction, thereby ensuring that the wind and sand flow can smoothly enter the feed box 10 for monitoring. Multiple online environment monitoring systems are arranged at different heights in the vertical direction, and wind and sand flows at different heights can be monitored at the same time to obtain multi-dimensional wind and sand flow data.

[0084] The design of the swivel and the spoiler 70 enables the online environmental monitoring system to automatically align with the wind direction, improves the accuracy and effectiveness of the device's monitoring of wind and sand flow, and ensures that the monitoring data can truly reflect the situation of the wind and sand flow in a specific direction. The layered arrangement of multiple devices in the vertical direction can fully understand the characteristics of wind and sand flows at different heights, such as the changing laws of parameters such as gravel content and wind speed, and provides rich multi-dimensional data for in-depth research on the movement laws and erosion capabilities of wind and sand, which helps to more comprehensively and accurately analyze wind and sand phenomena and their impact on the environment.

[0085] Two adjacent pairs of monitoring devices at the same height can be arranged, so that when one of the monitoring devices is drying the gravel, the wind-blown sand at this height can continue to be measured.

[0086] The dust removal cloth 20 is a fabric material with certain air permeability. For example, it is formed by interweaving fibers, and there are tiny gaps between the fibers, which can allow airflow to pass through while blocking grit.

[0087] Good air permeability: The fixed dust removal cloth 20 at the entrance of the upper air inlet channel 102 ensures that the ambient airflow can pass smoothly, and only filters out the sand and impurities therein, so that the airflow entering the upper air inlet channel 102 is relatively pure. This shows that the pore structure of the dust removal cloth 20 can block solid particles while allowing gas molecules to pass freely, without causing excessive obstruction to the airflow.

[0088] The core function of the dust removal cloth 20, whether in the upper air inlet channel 102 or the lower air inlet channel 103, is to filter the sand, which means that the fiber interlaced structure of the dust removal cloth 20 or the microstructure on its surface can effectively intercept the sand and prevent it from entering the channel, thereby ensuring that the airflow entering the device is relatively pure and does not affect subsequent measurements.

[0089] Other replacement structures can use metal filters or plastic filters to replace the dust cloth 20. Metal filters, such as stainless steel filters, have high strength and corrosion resistance. They filter sand and gravel by precisely controlling the size of the mesh. For example, a filter with a suitable mesh size can be used, such as a 20-30 mesh filter, which can effectively block sand and gravel of a certain size while ensuring the passage of airflow. Plastic filters are relatively light and may be less expensive, such as nylon filters, which have a certain elasticity and toughness. However, the filter structure may be more easily clogged by large particles of sand and gravel than the dust cloth 20, and needs to be cleaned regularly.

[0090] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
