Description

Technical Field

[0001] The present invention relates to the technical field of desertification prevention and control monitoring, and in particular to an omnidirectional wind speed profile and wind-sand flow structure monitoring device. Background Art

[0002] In the fields of wind and sand movement research, meteorological monitoring and desertification prevention and control, accurate monitoring of wind speed profiles and wind and sand flow structures is crucial. Existing wind and sand flow monitoring devices mostly use rotating sand collectors and multi-sensor combined technology.

[0003] Traditional rotary sand collectors use a turntable to drive a sand collecting trough to collect sand. However, as the accumulated weight of the sand increases, the center of gravity of the turntable gradually deviates from the axis of rotation. When the amount of sand exceeds the design threshold, the turntable generates additional frictional resistance due to the offset of the center of gravity, and eventually becomes completely stuck and unable to continue rotating for monitoring. Traditional devices require regular disassembly of the sand collecting trough and flushing of residual sand with water to prevent sand from compacting and clogging the sensor. This process not only consumes a large amount of water resources, but also requires the sand sample to be dried to restore the monitoring function, which increases energy consumption and time costs. In addition, water washing may wash away fine sand particles or dissolve salts, destroying the original particle size distribution and chemical composition of the sand particles, affecting the accuracy of subsequent analysis.

[0004] For example, a full-section portable sand collector with application number CN202010485223.7 includes a supporting and fixing device and a wind-and-sand collecting device; the supporting and fixing device includes an aluminum rod, a lock, a steel chisel, a ground nail and a wind rope; the wind-and-sand collecting device includes a sand collecting box and a sand collecting bag; the sand collecting boxes are staggered on the aluminum rod so that the sand collector can collect wind-and-sand in its full section.

[0005] The above technical solution has some problems during use. As the sand and gravel increase during use, the weight changes, resulting in a shift in the center of gravity, which makes the turntable easily stuck, causing the detection data to be invalid, and it is impossible to monitor the wind speed. It is also not convenient to adjust the sand collection monitoring height according to the actual use position.

[0006] Therefore, it is necessary to invent an all-round wind speed profile and wind-sand flow structure monitoring device to solve the above problems. Summary of the Invention

[0010] Preferably, the sand collecting assembly further comprises: a plurality of connecting grooves, which are evenly distributed around the circumference of the dividing plate; when the connecting grooves overlap with the sand inlet, the sand inlet is connected; and when the connecting grooves intersect with the sand inlet, the sand inlet is closed.

[0011] Preferably, the sand collecting assembly further comprises: a flexible ring fixedly connected to a side of the sand collecting box close to the height detection assembly; a tray threadedly connected to the outside of the adjustment assembly, and the upper end of which is in sealing contact with the closed shell; the sand collecting box is placed in the tray.

[0012] Preferably, the height detection component includes: an auxiliary sleeve, which is fixedly mounted on the outside of the impeller and has a wavy lower end surface; a height sensor, which is fixedly connected to the outer side of the lower end of the adjustment component and is used to monitor the rotation speed of the auxiliary sleeve, and monitor the rotation speed of the impeller through the auxiliary sleeve; when the sand collecting box falls to the extreme position, the flexible ring is placed between the height sensor and the auxiliary sleeve.

[0018] The technical effects and advantages of the present invention are as follows:

[0019] 1. The present invention effectively achieves the purpose of uniform distribution of the center of gravity by providing an adjustment component and a sand collecting component. The sand collecting component is placed on the outside of the support rod and is fixed axially relative to the support rod. During the process of storing sand and gravel, its weight changes, but the center of gravity remains at the axial position of the support rod, avoiding the increase in the collection amount causing the wind speed component to be unable to rotate. Moreover, as the wind speed component rotates relative to the support rod, the sand and gravel are evenly dispersed in the sand collecting box.

[0020] 2. The present invention effectively improves the accuracy of wind speed monitoring by setting a wind speed component and a height detection component. When in use, the wind speed is determined by measuring the rotation speed of the impeller, and the rotation speed of the auxiliary casing is determined by monitoring the wave structure at the lower end of the auxiliary casing. By combining the data monitored by the two sensors, the current wind speed can be accurately determined. When the speed sensor fails, the wind speed can be determined by the impeller speed data detected by the height sensor, avoiding the problem of monitoring interruption caused by failure of some sensors.

[0021] 3. The present invention effectively reduces the workload of sand removal by providing a sand collecting component. When in use, the tray is removed, and then the sand collecting box is completely taken out, and then the collected sand and gravel are completely poured out, thereby avoiding the loss of sand and gravel and also avoiding the agglomeration of sand and gravel.

[0022] 4. The present invention effectively achieves the purpose of adjustable monitoring height by setting an adjustment component. When in use, the adjustment component is manually slid along the axis of the support rod. When adjusted to a suitable height from the ground, the locking screw is rotated by a tool to clamp the support rod. At this time, the height of the adjustment component is fixed, so that the monitoring level can be adjusted according to needs in different environments. By setting multiple components, the function of monitoring different heights at the same position can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides Figures 1 to 9 The device is a comprehensive wind speed profile and wind-sand flow structure monitoring device, comprising a support rod 1, which is fixedly mounted 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 the extension direction of the support rod 1 is ensured to be perpendicular to the ground; an adjustment component 2, which is slidably sleeved on the outside of the support rod 1, and the middle part can rotate relative to the support rod 1, and the adjustment component 2 can be fixed at any height position along the support rod 1 from the ground; a wind speed component 3, which is sleeved on the middle part of the adjustment component 2 and is used to detect wind speed. The wind speed component 3 can rotate relative to the support rod 1, and the wind The wind speed component 3 includes an air inlet 301 and an air outlet 302. The air flow enters 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, so that the wind speed component 3 detects the wind speed; the sand collecting component 4 is mounted on the lower end of the adjustment component 2 and is used to detect the amount of sand and dust. The sand collecting component 4 is placed at the lower end of the wind speed component 3 to collect sand and gravel contained in the air flow passing through the wind speed component 3; the height detection component 5 is used to detect the height of the sand collecting box 404, and can also monitor the operating status of the wind speed component 3, and when the wind speed component 3 is working normally, it can cooperate with the wind speed detection component to determine the wind direction.

[0035] Specifically, the sand collecting component 4 includes a stepped 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 opened in the circumference of the stepped plate 401, and the sand inlet 402 is placed on the side close to the air outlet 302, for connecting the wind speed component 3 and the sand collecting component 4, so that the sand and gravel in the wind speed component 3 enter the sand collecting component 4; a dividing plate 403, which is placed at the lower end of the stepped plate 401, for controlling the on and off of the sand inlet 402, the dividing plate 403 can rotate relative to the stepped plate 401, and a plurality of connecting grooves 405 are provided and 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 and gravel are 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 the bottom of the dividing plate 403; the sand collecting box 404, which is a semi-annular structure, is symmetrically arranged below 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, reducing the later workload and avoiding the loss of sand and gravel, and 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. When the dividing plate 403 enables the sand inlet 402 to be opened, the sand and gravel can fall into the sand collecting trough, and then the air flow is discharged through the air outlet 302.

[0036] It should be noted that the sand collecting component 4 is placed on the outside of the support rod 1. Its weight changes during the process of storing sand and gravel, but its center of gravity still remains at the axial position of the support rod 1, avoiding the wind speed component 3 from being unable to rotate as the collection amount increases.

[0037] More specifically, the wind speed component 3 also includes: an impeller 303, which is rotatably mounted in the middle of the adjustment component 2 and passes through the dividing 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 is pushed by the airflow to rotate relative to the adjustment component 2; a closed shell 304, which is mounted on the outside of the impeller 303, and the air inlet 301 and the air outlet 302 are respectively arranged on both sides of the closed shell 304, and on both sides of the circumference 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 airflow can push the impeller 303; a speed sensor 305, which is fixedly connected to the outside of the closed shell 304 and is used to monitor the rotation speed of the impeller 303. The speed sensor 305 can be a Hall sensor or a photoelectric encoder. The wind speed is determined by measuring the rotation speed of the impeller 303. The speed sensor 305 is electrically connected to a power supply and a data processing device so that the monitoring data can be recorded and sent to the data terminal of the management personnel.

[0038] Specifically, the sand collecting component 4 also includes: a flexible ring 406, which is fixedly connected to the side of the sand collecting box 404 close to the height detection component 5, and the other end of the flexible ring 406 is in contact with the dividing plate 403, so as to prevent the leakage of sand 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 sealing contact with the closed shell 304, and the tray 407 can rotate relative to the closed shell 304; the sand collecting box 404 is placed in the tray 407. When in use, the tray 407 is removed to take out the sand collecting box 404, and then the sand can be completely taken out, reducing the subsequent processing work of the sand.

[0039] More specifically, the height detection assembly 5 includes: an auxiliary sleeve 501, which is fixedly sleeved on the outside of the impeller 303 and has a wavy lower end surface;

[0040] The height sensor 502 is fixedly connected to the outer side of the lower end of the adjustment component 2 and is used to monitor the rotation speed of the auxiliary sleeve 501. The rotation speed of the impeller 303 is monitored through the auxiliary sleeve 501. The height sensor 502 can be an infrared sensor or a radar sensor. By monitoring the wave structure at the lower end of the auxiliary sleeve 501, the rotation speed of the auxiliary sleeve 501 is determined. When in use, the height sensor 502 is electrically connected to the corresponding power supply and data processing equipment so that the monitored data can be recorded and sent to the data terminal of the management personnel.

[0041] It should be noted that when the sand collecting box 404 falls to the extreme position, the flexible ring 406 is placed between the height sensor 502 and the auxiliary sleeve 501. During use, the amount of sand and gravel in the sand collecting box 404 gradually increases, and the sand collecting box 404 slides downward under the influence of gravity. When the sand collecting box 404 slides to the lower extreme position, the flexible ring 406 will block the height sensor 502, causing the height sensor 502 to detect a height that is significantly lower than its distance from the auxiliary sleeve 501. This indicates that the sand collecting box 404 is full, and the management personnel are then notified to clean the sand and gravel in the sand collecting box 404 and record the amount of sand and gravel.

[0042] It should be pointed out that when the difference between the impeller 303 speed detected by the speed sensor 305 and the impeller 303 speed detected by the height sensor 502 is greater than D, it indicates that the speed sensor 305 or the height sensor 502 has a fault. At this time, the management personnel are reminded to maintain the device and eliminate the fault point; when the speed sensor 305 fails, the wind speed can be determined by the impeller 303 speed data detected by the height sensor 502; when the speed sensor 305 and the height sensor 502 detect that the rotation amount of the impeller 303 is different and the difference is less than D, and the detection data are restored to the same before the difference is greater than D, it indicates that the wind speed component 3 has rotated 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 by the difference D (D is the value of one rotation of the impeller 303).

[0043] Specifically, the adjustment component 2 includes: a lower fixed tube 201 and an upper fixed tube 202, which are respectively slidably mounted on the outside of the support rod 1, the upper fixed tube 202 passes through the top of the closed shell 304, the lower fixed tube 201 passes through the tray 407, and the tray 407 is threadedly matched with the lower fixed tube 201; a rotating sleeve 203, which is placed between the lower fixed tube 201 and the upper fixed tube 202, and the upper and lower ends are respectively rotatably connected to the upper fixed tube 202 and the lower fixed tube 201 through bearings, and the impeller 303 is rotatably mounted on the outside of the rotating sleeve 203; a locking screw 204, which is respectively threadedly mounted on the middle part of the lower fixed tube 201 and the upper fixed tube 202, for fixing the position of the lower fixed tube 201 and the upper fixed tube 202 relative to the support rod 1. When in use, the adjustment component 2 is manually slid along the axis of the support rod 1. When adjusted to a suitable height from the ground, the locking screw 204 is rotated by a tool to clamp the support rod 1. At this time, the height of the adjustment component 2 is fixed.

[0044] It should be noted that the locking screw adopts a countersunk design so that the tray 407 can cooperate with the thread of the lower fixing tube 201.

[0045] More specifically, the sand collecting assembly 4 also includes a limiting sleeve 408, the lower end of which is fixedly connected to the outer side of the lower fixed tube 201, and the upper end is fixedly connected to the dividing plate 403. The setting of the limiting sleeve 408 prevents the dividing 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 and the connecting groove 405 overlap / intersect, and the overlap causes the sand to fall into the sand collecting box 404. When intersecting, the airflow is prevented from forming a low-pressure area at the sand inlet 402, causing the sand to leak from the sand collecting box 404. The end is provided with a plurality of vertically arranged guide grooves 411; the limiting boss 409 is fixedly connected to the lower end of the corresponding sand collecting box 404, and the limiting boss 409 can slide along the corresponding guide groove 411. The guide groove 411 and the limiting boss 409 cooperate with each other so that the sand collecting box 404 can only slide relative to the lower fixed tube 201. Therefore, when the closed shell 304 rotates, the sand inlet 402 moves so that sand can enter the two sand collecting boxes 404; the support spring 410 is fixedly connected to the middle of the tray 407, and the other end is in contact with the sand collecting box 404, and is used to support the sand collecting box 404.

[0046] Specifically, it also includes; a filter screen 6, which is arranged obliquely in the air outlet 302 and close to the sand inlet 402, for filtering out sand and gravel in the air flow and guiding the sand and gravel into the sand inlet 402. The filter screen 6 is fixed in the air outlet 302 by screws for easy replacement and dredging. The filter screen 6 can filter out solid particles in the air flow passing through the wind speed component 3.

[0047] It should be noted that the filter screen 6 is set at an angle so that its contact area with the air flow is increased, and the inclined setting can make the filtered solid particles fall along the inclined surface and enter the sand inlet 402; as the wind speed component 3 rotates, the filter screen 6 will produce a small amplitude vibration, thereby achieving the purpose of clearing through the filter screen 6.

[0048] More specifically, it also includes; a guide plate 7, which is fixedly connected to one side of the closed shell 304 and corresponds to the air outlet 302, and is used to cooperate with the adjustment component 2 to make the air inlet 301 correspond to the airflow direction. When in use, the guide plate 7 is affected by the airflow and changes direction, so that the air inlet 301 can correspond to the airflow direction, allowing air to enter the wind speed component 3.

[0049] Specifically, the number of adjustment components 2, wind speed components 3, sand collection components 4 and height detection components 5 is the same, and there are multiple adjustment components 2, wind speed components 3, sand collection components 4 and height detection components 5. Multiple adjustment components 2, wind speed components 3, sand collection components 4 and height detection components 5 are all arranged at the upper end of the support rod 1, and at different heights, to monitor the amount of sand and dust in the air flow at different heights at the same position.

[0050] In summary, the support rod 1 is fixed to the ground by expansion screws or other fixing methods, and then the height of the adjustment component 2 from the ground is manually adjusted. After adjusting to the appropriate height, the locking screw 204 is rotated by a tool to clamp the support rod 1. Then the sand collecting box 404 is placed in the tray 407, and the sand collecting box 404 is rotated and connected to the outside of the lower fixed tube 201. Then the wind speed and the amount of windblown sand in the air can be monitored.

[0051] During use, the air flow enters the closed shell 304 through the air inlet and drives the impeller 303 to rotate. The rotation speed of the impeller 303 is measured by the speed sensor 305 to determine the wind speed, and the monitoring data is recorded and sent to the data terminal of the administrator. At the same time, the height sensor 502 monitors the rotation speed of the auxiliary sleeve 501. By comparing the data of the speed sensor 305, it is determined whether the impeller 303 and the speed sensor 305 are working normally. At this time, solid particles such as sand and gravel in the air flow will fall on the step plate 401 due to gravity, and be pushed by the impeller 303 into the sand inlet 402. At the same time, the air flow passes through the filter 6 in the air outlet 302 and is discharged from the wind speed component 3. The filter 6 filters out the remaining particles in the air flow and guides them into the sand inlet 402.

[0052] As the wind direction changes, the guide plate 7 rotates under the influence of the airflow, so that the air inlet always corresponds to the airflow direction, allowing 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 step plate 401 rotates, so that the sand inlet 402 overlaps with the connecting 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, causing the height sensor 502 to detect a height that is significantly less than its distance from the auxiliary sleeve 501. At this time, it indicates that the sand collecting box 404 is full, and then 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.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
