Description

Technical Field

[0001] The present invention relates to the technical field of desertification prevention and control monitoring, and particularly relates to a device for monitoring the omnidirectional wind speed profile and the structure of wind-blown sand flow. Background Technique

[0002] In the fields of wind-blown sand movement research, meteorological monitoring, and desertification prevention and control, the accurate monitoring of the wind speed profile and the structure of wind-blown sand flow is crucial. Existing wind-blown sand monitoring devices mostly adopt the technology of combining a rotary sand collector and multiple sensors.

[0003] The traditional rotary sand collector drives the sand collecting trough through a turntable to collect sand grains. However, as the cumulative weight of the sand grains increases, the center of gravity of the turntable gradually deviates from the rotation axis. When the sand volume exceeds the design threshold, the turntable generates additional frictional resistance due to the center-of-gravity shift and finally gets completely stuck and cannot continue to rotate for monitoring. The traditional device needs to regularly disassemble the sand collecting trough and wash the residual sand grains with water to avoid sand grain caking and blocking the sensor. This process not only consumes a large amount of water resources, but also requires drying the sand samples to restore the monitoring function, additionally increasing the energy consumption and time cost. In addition, water washing may wash away fine-grained sand or dissolve salts, destroying the original particle size distribution and chemical composition of the sand grains and affecting the accuracy of subsequent analysis.

[0004] For example, a full-section portable sand collector with the application number CN202010485223.7 includes a support and fixing device and a wind-blown sand collection device; the support and fixing device includes an aluminum rod, a buckle, a steel drill, a ground nail, and a wind rope; the wind-blown sand collection device includes a sand collection box and a sand collection bag; the sand collection boxes are arranged alternately on the aluminum rod so that the sand collector can collect wind-blown sand in a full section.

[0005] There are some problems in the above technical solution during use. During use, as the gravel increases, the weight changes, resulting in a center-of-gravity shift and making the turntable prone to getting stuck, causing the detection data to become invalid, and it is also impossible to monitor the wind speed, nor is it convenient to adjust the monitoring height of sand collection according to the actual use position.

[0006] Therefore, it is very necessary to invent a device for monitoring the omnidirectional wind speed profile and the structure of wind-blown sand flow to solve the above problems. Summary of the Invention

When the partition plate makes the sand inlet conduct, the sand and gravel can fall into the sand collection groove; a height detection component for detecting the height of the sand collection box and capable of monitoring the operating state of the wind speed component.

[0009] Preferably, the wind speed component further includes: an impeller rotatably sleeved in the middle of the adjustment component and penetrating through the partition plate and the stepped plate, and the impeller can rotate relative to the adjustment component under the push of the air flow; an enclosing shell sleeved outside the impeller, with the air inlet and the air outlet respectively placed on both sides of the enclosing shell; a rotation speed sensor fixedly connected to the outside of the enclosing shell for monitoring the rotation speed of the impeller.

[0010] Preferably, the sand collection component further includes: a plurality of communication grooves evenly distributed in the circumferential direction of the partition plate. When the communication grooves overlap with the sand inlet, the sand inlet conducts; when the communication grooves and the sand inlet are staggered, the sand inlet is closed.

[0011] Preferably, the sand collection component further includes: a flexible ring fixedly connected to the side of the sand collection box close to the height detection component; a tray threadedly connected to the outside of the adjustment component and having its upper end in sealed contact with the enclosing shell; the sand collection box is placed in the tray.

[0012] Preferably, the height detection component includes: an auxiliary sleeve fixedly sleeved outside the impeller and having a wavy lower end face; a height sensor fixedly connected to the outside of the lower end of the adjustment component for monitoring the rotation speed of the auxiliary sleeve and monitoring the rotation speed of the impeller through the auxiliary sleeve; when the sand collection box drops to the limit position, the flexible ring is placed between the height sensor and the auxiliary sleeve.

[0013] Preferably, the adjustment assembly includes a lower fixed tube and an upper fixed tube which are respectively sleeved outside the support rod in a sliding manner; a rotating sleeve which is disposed between the lower fixed tube and the upper fixed tube, and the upper and lower ends of which are respectively rotatably connected to the upper fixed tube and the lower fixed tube through bearings; locking screws which are respectively threadedly installed in the middle parts of the lower fixed tube and the upper fixed tube for fixing the positions of the lower fixed tube and the upper fixed tube relative to the support rod; and the tray is in threaded fit with the lower fixed tube.

[0014] Preferably, the sand collection assembly further includes a limit sleeve whose lower end is fixedly connected to the outside of the lower fixed tube and whose upper end is fixedly connected to the partition plate, and a plurality of vertically arranged guiding chutes are opened at the lower end of the limit sleeve; a limit boss which is fixedly connected to the lower end of the corresponding sand collection box, and the limit boss can slide along the corresponding guiding chute; and a support spring which is fixedly connected to the middle part of the tray and the other end of which contacts the sand collection box for supporting the sand collection box.

[0018] The technical effects and advantages of the present invention: 1. By setting the adjustment assembly and the sand collection assembly, the present invention effectively achieves the purpose of uniform distribution of the center of gravity. The sand collection assembly is disposed outside the support rod and axially fixed relative to the support rod. During the process of storing gravel, although the weight changes, the center of gravity still remains at the axis position of the support rod, avoiding the situation that the wind speed assembly cannot rotate due to the increase in the collection amount. And as the wind speed assembly rotates relative to the support rod, the gravel is also evenly dispersed in the sand collection box.

[0019] 2. By setting the wind speed assembly and the height detection assembly, the present invention effectively improves the accuracy of wind speed monitoring. When in use, the wind speed is judged by measuring the rotation speed of the impeller, and at the same time, the rotation speed of the auxiliary sleeve is judged by monitoring the wave structure at the lower end of the auxiliary sleeve. By combining the data monitored by the two sensors, the current wind speed is accurately judged. And when the rotation speed sensor fails, the wind speed can be judged by the impeller rotation speed data detected by the height sensor, avoiding the problem of monitoring interruption caused by the failure of some sensors.

[0020] 3. By setting up a sand collection component, the present invention effectively reduces the workload of sand removal. When in use, the tray is removed, and then the sand collection box is taken out completely. Next, the collected sand and gravel are poured out completely, avoiding the loss of sand and gravel and preventing the sand and gravel from caking.

[0021] 4. By setting up an adjustment component, the present invention effectively achieves the purpose of adjustable monitoring height. When in use, manually slide the adjustment component along the axis of the support rod. After adjusting to a suitable height from the ground, use a tool to rotate the locking screw to clamp the support rod. At this time, the height of the adjustment component is fixed, achieving the function of adjusting the monitoring horizontal height according to requirements in different environments. By setting multiple adjustment components, the function of monitoring different heights at the same position can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides a Figures 1 to 9 comprehensive wind speed profile and aeolian sand flow structure monitoring device as shown in the figure, including a support rod 1 fixedly installed on a flat ground. The bottom of the support rod 1 is disc-shaped and is fixed to the ground by expansion screws or other fixing methods, and it is ensured that the extending direction of the support rod 1 is perpendicular to the ground; an adjustment component 2 slidably sleeved outside the support rod 1, and the middle part can rotate relative to the support rod 1. The adjustment component 2 can be fixed at any height position along the support rod 1 from the ground; a wind speed component 3 sleeved in the middle of the adjustment component 2 for detecting wind speed. The wind speed component 3 can rotate relative to the support rod 1. The wind speed component 3 includes an air inlet 301 and an air outlet 302. Air flows into the wind speed component 3 through the air inlet 301 and is discharged through the air outlet 302. The air flow passes through the wind speed component 3, enabling the wind speed component 3 to detect the wind speed; a sand collection component 4 sleeved at the lower end of the adjustment component 2 for detecting the sand dust amount. The sand collection component 4 is placed at the lower end of the wind speed component 3 to collect the sand and gravel contained in the air flow passing through the wind speed component 3; a height detection component 5 for detecting the height of the sand collection box 404 and capable of monitoring the operating state of the wind speed component 3. When the wind speed component 3 is working properly, it can cooperate with the wind speed detection component to measure the wind direction.

[0034] Specifically, the sand collecting component 4 includes a step plate 401, which is placed below the wind speed component 3 and has a sand inlet 402 on one side. The sand inlet 402 is arranged in the circumference of the step plate 401, and the sand inlet 402 is placed on a side close to the air outlet 302, for connecting the wind speed component 3 and the sand collecting component 4, so that the sand in the wind speed component 3 enters the sand collecting component 4; a dividing plate 403, which is placed at the lower end of the step plate 401, for controlling the on and off of the sand inlet 402, the dividing plate 403 can rotate relative to the step plate 401, and a plurality of connecting grooves 405 are provided and are evenly distributed in the circumference of the dividing plate 403. When the connecting grooves 405 overlap with the sand inlet 402, the sand inlet 402 is connected, and when the connecting grooves 405 and the sand inlet 402 are staggered, the sand inlet 402 is closed. When in use, the sand inlet 402 is closed, and the sand is placed in the sand inlet 402, and Placed at the upper end of the dividing plate 403, when the dividing plate 403 rotates relative to the step plate 401, the sand inlet 402 overlaps with the connecting groove 405, allowing the sand and gravel to enter under the dividing plate 403; the sand collecting box 404, which is a semi-annular structure, is symmetrically arranged under the dividing plate 403 for storing sand and gravel. The semi-annular design enables the sand collecting box 404 to be completely taken out, so that the collected sand and gravel can be completely poured out without flushing it out with water and drying it, thereby reducing the workload in the later stage and avoiding the loss of sand and gravel. As the wind speed component 3 rotates relative to the support rod 1, the sand and gravel are also evenly dispersed in the sand collecting box 404; the air flow enters the wind speed component 3 through the air inlet 301, and causes the sand and gravel in the air flow to fall into the sand inlet 402. The dividing plate 403 enables the sand and gravel to fall into the sand collecting trough when the sand inlet 402 is turned on, and then the air flow is discharged through the air outlet 302.

[0035] It should be noted that the sand collecting assembly 4 is placed outside the support rod 1. Its weight changes during the process of storing sand and gravel, but its center of gravity remains at the axial position of the support rod 1 to avoid the wind speed assembly 3 being unable to rotate as the collection amount increases.

[0036] More specifically, the wind speed component 3 further includes: an impeller 303, which is rotatably sleeved in the middle of the adjustment component 2 and penetrates through the partition plate 403 and the stepped plate 401. The blades of the impeller 303 are arc-shaped, so that the impeller 303 can only rotate to one side. The impeller 303 can rotate relative to the adjustment component 2 under the push of the air flow; a closed shell 304, which is sleeved outside the impeller 303. The air inlet 301 and the air outlet 302 are respectively arranged on both sides of the closed shell 304 and are arranged on the circumferential sides of the impeller 303. There is a small gap between the middle of the closed shell 304 and the blades of the impeller 303, so that the air flow can push the impeller 303; a rotational speed sensor 305, which is fixedly connected to the outside of the closed shell 304 and is used to monitor the rotational speed of the impeller 303. The rotational speed sensor 305 can be a Hall sensor or an optoelectronic encoder. By measuring the rotational speed of the impeller 303, the wind speed is judged. The rotational speed sensor 305 is electrically connected to a power supply and a data processing device, so that the monitored data can be recorded and sent to the data terminal of the management personnel.

[0037] Specifically, the sand collection component 4 further includes: a flexible ring 406, which is fixedly connected to one side of the sand collection box 404 close to the height detection component 5. The other end of the flexible ring 406 contacts the partition plate 403 to prevent sand and gravel from leaking when the sand box moves up and down; a tray 407, which is threadedly connected to the outside of the adjustment component 2 and the upper end is in sealed contact with the closed shell 304. The tray 407 can rotate relative to the closed shell 304; the sand collection box 404 is placed in the tray 407. When in use, the tray 407 is removed, and then the sand collection box 404 can be taken out, and then the sand and gravel can be completely taken out, reducing the subsequent processing work of the sand and gravel.

[0038] More specifically, the height detection component 5 includes: an auxiliary sleeve 501, which is fixedly sleeved outside the impeller 303 and the lower end surface is wavy; A height sensor 502, which is fixedly connected to the outside of the lower end of the adjustment component 2 and is used to monitor the rotational speed of the auxiliary sleeve 501. By monitoring the rotational speed of the auxiliary sleeve 501, the rotational speed of the impeller 303 is monitored. The height sensor 502 can be an infrared sensor or a radar sensor. By monitoring the wavy structure at the lower end of the auxiliary sleeve 501, the rotational speed of the auxiliary sleeve 501 is judged. When in use, the height sensor 502 is electrically connected to a corresponding power supply and a data processing device, so that the monitored data can be recorded and sent to the data terminal of the management personnel.

[0039] It should be noted that when the sand collection box 404 drops to the limit position, the flexible ring 406 is placed between the height sensor 502 and the auxiliary sleeve 501. During use, the amount of grit in the sand collection box 404 gradually increases. Affected by gravity, the sand collection box 404 slides downward. When the sand collection box 404 slides to the lower limit position, the flexible ring 406 will block the height sensor 502, causing the height sensor 502 to detect a height significantly less than its distance from the auxiliary sleeve 501. At this time, it indicates that the sand collection box 404 is full. Subsequently, the management staff is notified to clean the grit in the sand collection box 404 and record the amount of grit.

[0040] It should be pointed out that when the difference between the rotational speed of the impeller 303 detected by the rotational speed sensor 305 and the rotational speed of the impeller 303 detected by the height sensor 502 is greater than D, it indicates that the rotational speed sensor 305 or the height sensor 502 has failed. At this time, the management staff is reminded to maintain the device and eliminate the fault point; when the rotational speed sensor 305 fails, the wind speed can be judged based on the rotational speed data of the impeller 303 detected by the height sensor 502; when the rotational amounts of the impeller 303 detected by the rotational speed sensor 305 and the height sensor 502 are different and the difference is less than D, and the detected data returns to the same before the difference is greater than D, it indicates that the wind speed component 3 rotates relative to the support rod 1, and the rotation angle is D / 360°. When the initial angle of the wind speed component 3 relative to the support rod 1 is known, the wind direction can be determined through the difference D (D is the value for one full rotation of the impeller 303).

[0041] Specifically, the adjustment component 2 includes: a lower fixed pipe 201 and an upper fixed pipe 202, which are respectively slidably sleeved outside the support rod 1. The upper fixed pipe 202 penetrates through the top end of the closed shell 304, and the lower fixed pipe 201 penetrates through the tray 407. The tray 407 is in threaded cooperation with the lower fixed pipe 201; a rotating sleeve 203, which is placed between the lower fixed pipe 201 and the upper fixed pipe 202, and the upper and lower ends are respectively rotatably connected to the upper fixed pipe 202 and the lower fixed pipe 201 through bearings. The impeller 303 is rotatably sleeved outside the rotating sleeve 203; a locking screw 204, which is respectively threadedly installed in the middle of the lower fixed pipe 201 and the upper fixed pipe 202, and is used to fix the positions of the lower fixed pipe 201 and the upper fixed pipe 202 relative to the support rod 1. During use, manually slide the adjustment component 2 along the axis of the support rod 1. When adjusted to a suitable height from the ground, use a tool to rotate the locking screw 204 to clamp the support rod 1. At this time, the height of the adjustment component 2 is fixed.

[0042] It should be noted that the locking screw is designed with a countersunk head, enabling the tray 407 to be in threaded cooperation with the lower fixed pipe 201.

[0043] More specifically, the sand collecting assembly 4 further includes: a limiting sleeve 408, the lower end of which is fixedly connected to the outside of the lower fixed pipe 201, and the upper end is fixedly connected to the partition plate 403. The arrangement of the limiting sleeve 408 prevents the partition plate 403 from rotating relative to the support rod 1. Therefore, when the wind direction changes, the closed shell 304 drives the stepped plate 401 to rotate. At this time, the sand inlet 402 overlaps / staggers with the communication groove 405. When they overlap, the grit falls into the sand collecting box 404. When they are staggered, it avoids the formation of a low-pressure area at the sand inlet 402, causing the grit to leak from the sand collecting box 404. A plurality of vertically arranged guiding chutes 411 are provided at the lower end of the limiting sleeve 408; a limiting boss 409, which is fixedly connected to the lower end of the corresponding sand collecting box 404. The limiting boss 409 can slide along the corresponding guiding chute 411. The cooperation between the guiding chute 411 and the limiting boss 409 enables the sand collecting box 404 to only slide relative to the lower fixed pipe 201. Therefore, when the closed shell 304 rotates, the movement of the sand inlet 402 allows the grit to enter the two sand collecting boxes 404; a support spring 410, which is fixedly connected to the middle of the tray 407 and contacts the sand collecting box 404 at the other end, for supporting the sand collecting box 404.

[0044] Specifically, it further includes: a filter screen 6, which is inclined in the air outlet 302 and close to the sand inlet 402, for filtering out the grit in the air flow and guiding the grit into the sand inlet 402. The filter screen 6 is fixed in the air outlet 302 by screws, which is convenient for replacement and dredging. The filter screen 6 can filter out the solid particles in the air flow passing through the wind speed assembly 3.

[0045] It should be noted that the filter screen 6 is inclined, which increases its contact area with the air flow, and the inclined setting enables the filtered solid particles to fall along the inclined surface and enter the sand inlet 402; as the wind speed assembly 3 rotates, the filter screen 6 will vibrate slightly, achieving the purpose of dredging the filter screen 6.

[0046] More specifically, it further includes: a guide plate 7, which is fixedly connected to one side of the closed shell 304 and corresponds to the air outlet 302, for cooperating with the adjustment assembly 2 to make the air inlet 301 correspond to the air flow direction. When in use, the guide plate 7 changes its direction under the influence of the air flow, so that the air inlet 301 can correspond to the air flow direction, enabling the air to enter the wind speed assembly 3.

[0047] Specifically, the adjustment assembly 2, the wind speed assembly 3, the sand collecting assembly 4 and the height detection assembly 5 are the same in number and are respectively provided with a plurality of them. A plurality of adjustment assemblies 2, wind speed assemblies 3, sand collecting assemblies 4 and height detection assemblies 5 are all arranged at the upper end of the support rod 1 and have different heights, for monitoring the sand content of the air flow at the same position but different heights.

[0048] In summary, the support rod 1 is fixed to the ground by expansion screws or other fixing methods. Subsequently, manually adjust the height of the adjustment assembly 2 from the ground. After adjusting to the appropriate height, rotate the locking screw 204 with a tool to clamp the support rod 1. Then, place the sand collecting box 404 in the tray 407 and rotatably connect the sand collecting box 404 to the outside of the lower fixed pipe 201. Subsequently, the wind speed and sand volume in the air can be monitored.

[0049] During use, the air flow enters the closed shell 304 through the air inlet and pushes the impeller 303 to rotate. The rotation speed of the impeller 303 is measured by the rotation speed sensor 305 to determine the wind speed. The monitoring data is recorded and sent to the data terminal of the management personnel. At the same time, the height sensor 502 monitors the rotation speed of the auxiliary sleeve 501. By comparing the data of the rotation speed sensor 305, it is judged whether the impeller 303 and the rotation speed sensor 305 are working properly. At this time, solid particles such as sand and gravel in the air flow will fall on the stepped plate 401 under the influence of gravity and be pushed by the impeller 303 into the sand inlet 402. At the same time, the air flow passes through the filter screen 6 in the air outlet 302 and is discharged from the wind speed assembly 3. The filter screen 6 filters out the residual particles in the air flow and guides them into the sand inlet 402.

[0050] With the change of the wind direction, the guide plate 7 rotates under the influence of the air flow, so that the air inlet always corresponds to the air flow direction, enabling the gas to enter the closed shell 304 through the air inlet hole. The guide plate 7 drives the closed shell 304 to rotate relative to the support rod 1. At the same time, the stepped plate 401 rotates, so that the sand inlet 402 overlaps with the communication groove 405, and the sand and gravel fall into the sand collecting box 404. The sand collecting box 404 slides downward under the influence of gravity. When the sand collecting box 404 slides to the lower limit position, the flexible ring 406 will block the height sensor 502, so that the height sensor 502 detects a height significantly less than its distance from the auxiliary sleeve 501. At this time, it indicates that the sand collecting box 404 is full. Subsequently, the management personnel are notified to clean the sand and gravel in the sand collecting box 404 and record the amount of sand and gravel.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
