Description

Technical Field

[0001] The invention relates to the technical field of sand and dust detection, and in particular to a device for detecting sand and dust content in a wind-blown sand flow. Background Art

[0002] The direct indicator of the intensity of soil wind erosion and sand activity is sand flux. Monitoring of near-surface sand activity is the main content of ground monitoring of soil wind erosion, which mainly monitors the sand flow. The monitoring results can provide basic data for soil wind erosion detection and forecasting.

[0003] For example, a Chinese utility model patent with a publication number of CN205157389U discloses a device for detecting the sand content in a wind-blown sand flow, the structure of which includes a sand collecting unit for collecting and weighing the sand in the wind-blown sand flow, a fixed bracket for fixing the sand collecting unit at a monitoring site of near-ground wind-blown sand activities, a data collector electrically connected to the sand collecting unit to collect weight data of the sand in the wind-blown sand flow, and a power supply for providing working voltage to the data collector and the sand collecting unit.

[0004] The above solution has the following shortcomings in actual use:

[0005] This solution adopts a downward inclined section to reduce the wind pressure to a certain extent, creating favorable conditions for subsequent decompression, and can automatically collect and record sand and dust data in the air. However, in actual use, the above structure is a fixed structure. Although it can detect the sand and dust content at different heights, when the above structure is in an environment with more complex wind direction, it is impossible to effectively collect sand, and the opening size of the above structure for sand collection is unchanged. When the sand and dust content in the air is low, the collection amount will be small, resulting in inaccurate detection results. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0032] like Figure 1 and Figure 2As shown, a device for detecting the sand content in a wind-blown sand flow comprises a storage unit 100, a support unit 200, a sand collecting unit 300 and a fixing unit 400. The storage unit 100 is used to store the support unit 200, the sand collecting unit 300 and the fixing unit 400, so as to facilitate the staff to carry and install the device. A plurality of support units 200 can be arranged on the storage unit 100 as needed. When it is necessary to detect the sand content in a relatively complex wind direction environment, by placing a plurality of support units 200 on the upper surface of the storage unit 100, the sand collecting unit 300 faces different directions, so that the sand can be collected in all directions. In this process, the sand content in the wind-blown sand flow is detected by comprehensively calculating the weight of the collected sand, such as Figure 3 As shown, when it is necessary to detect the wind and sand content in the air at different heights, a plurality of support units 200 are stacked and then fixed by a fixing unit 400 .

[0033] It should be noted that the storage unit 100 is also provided with a controller, a battery and a remote signal transmission unit. The controller is used to process the data information detected by the sand collection unit 300, and then send the processed information under the action of the remote signal transmission unit.

[0034] like Figure 4 As shown, the storage unit 100 includes a storage box body 101, which is connected to the top cover 102 through a lock 103. The top cover 102 is provided with a plurality of sockets 104 for plugging in the support unit 200. The number of the sockets 104 is five, one of which is located in the middle of the top cover 102, and the other four sockets 104 are arranged circumferentially on the top cover 102.

[0035] like Figure 5 and Figure 6As shown, the support unit 200 includes a column 201, a plug connector 202 is provided at the bottom end of the column 201, a plug slot 203 corresponding to the plug connector 202 is provided at the top end of the column 201, a connecting piece and two extension arms 213 are provided on the column 201, an adjusting piece is provided at the end of one of the extension arms 213, and the opening size of the elastic strip 301 is adjusted by the adjusting piece, and a tail wing 222 is plugged at the end of the other extension arm 213, and the tail wing 222 is a hollow structure. By providing the tail wing 222, the extension arm 213 can be extended under the action of wind. The arm 213 is deflected so that the sand collecting unit 300 can correspond to the wind direction. The extension arm 213 is quickly disassembled by setting a connecting piece, which further improves the convenience of the staff in installing the device. When the columns 201 are stacked, the installation work can be completed by inserting the plug connector 202 at the bottom end of the upper column 201 into the plug slot 203 at the top end of the lower column 201. When performing all-round wind and sand collection, the plug connectors 202 at the bottom ends of multiple columns 201 are inserted into the axially arranged plug sockets 104 in sequence.

[0036] like Figure 8 As shown, the connecting member includes a fixed seat 204, the inner wall of the fixed seat 204 is slidably connected with a clamping block 205, the fixed seat 204 is threadedly connected with a locking screw 206 for driving the clamping block 205 to move, and connecting plates 207 are arranged on both sides of the fixed seat 204, and the connecting plate 207 is provided with a threaded column 208 and an adjusting ring 209 for driving the threaded column 208 to move up and down, the adjusting ring 209 is rotatably connected to the connecting plate 207, the threaded column 208 is sleeved with the connecting plate 207, and the tops of the two threaded columns 208 are provided with a bearing plate 210, and the bearing plate 210 is rotatably connected with the seat body 21 1. The seat body 211 is plugged with the extension arm 213 through the slot 212. The clamping block 205 is moved by rotating the locking screw 206 until the clamping block 205 and the column 201 are tightly fitted to achieve the height limitation of the fixed seat 204. By rotating the adjusting ring 209, the threaded column 208 pushes the bearing plate 210 up and down under the action of the thread, and the height of the fixed seat 204 can be fine-tuned, which is convenient and quick. The bearing plate 210 is connected to the seat body 211 through a bearing, so that it can cooperate with the tail wing 222 to improve the accuracy of adjusting the sand collecting unit 300.

[0037] like Figure 7As shown, the adjusting member includes a mounting shell 214, to which an adjusting shaft 215 is rotatably connected, a worm 216 is provided on one side of the adjusting shaft 215, a plurality of worm wheels 217 are meshingly connected to the worm 216, the worm wheel 217 is rotatably connected to the inner wall of the mounting shell 214 through a bracket 218, the worm wheel 217 is connected to an adjusting arm 219 through a rotating shaft, a connecting rod 220 is provided on the adjusting arm 219, a fixing block 221 is provided at the end of the connecting rod 220, and the fixing block 221 is connected to the elastic strip 301.

[0038] It should be noted that when it is necessary to detect the wind and sand content under a relatively complex wind direction environment, multiple support units 200 are placed on the upper surface of the storage unit 100 so that the sand collecting unit 300 faces different directions. In this state, in order to avoid the orientation of the sand collecting unit 300 being offset under the action of the tail wing 222, during installation, the staff does not need to install the tail wing 222 and the extension arm 213 connected to the tail wing 222. In order to improve the collection effect of sand and dust, the elastic strip 301 is adjusted through the adjustment piece to increase the opening of the elastic strip 301 until the sides of two adjacent elastic strips 301 are abutted against each other, and at the same time, the fixed blocks 221 in two adjacent adjustment pieces are abutted against each other, thereby limiting the change in the opening direction of the filter screen 302 in the sand collecting unit 300, thereby achieving all-round collection of wind and sand.

[0039] like Fig. 9 As shown, the sand collecting unit 300 includes an elastic strip 301 connected end to end, a filter screen 302 is arranged on one side of the elastic strip 301, a sand delivery pipe 303 is arranged at the outlet of the filter screen 302, a bucket cover 304 is arranged at the end of the sand delivery pipe 303, the bucket cover 304 is threadedly connected to a barrel body 305, a sand collecting bucket 307 and a weight sensor 306 for weighing the sand collecting bucket 307 are arranged in the barrel body 305, a bearing member 308 is arranged below the barrel body 305, the bearing member 308 is connected to the support unit 200, and the bearing member 308 is threadedly connected to the barrel body 305 through a connecting ring 309.

[0040] In order to avoid the phenomenon that the filter screen 302 has a poor sand collection effect due to folding, the connecting rod 220 is at least partially connected to the filter screen 302 to avoid the filter screen 302 from blocking the sand delivery pipe 303 when the filter screen 302 is folded again. The filter screen 302 is made of elastic material. When the opening size of the elastic strip 301 needs to be adjusted, the adjusting arm 219 drives the connecting rod 220 to start turning under the transmission of the worm 216 and the worm gear 217 by rotating the adjusting shaft 215, so as to adjust the opening size of the elastic strip 301. When collecting sand, when the air carries the sand through the filter screen 302, the sand is blocked by the filter screen 302 and then falls into the sand delivery pipe 303, and then falls into the sand collecting bucket 307. Then, under the action of the controller, the weight sensor 306 regularly detects the weight of the sand in the sand collecting bucket 307.

[0041] like Fig.10 As shown, the fixing unit 400 includes a top plate 401, which is in a cross-shaped structure. A plurality of ropes 404 are arranged on the top plate 401, and fixing cones 405 are arranged at the ends of the ropes 404. A plurality of plug-in blocks 402 are arranged on the lower surface of the top plate 401. The number of the plug-in blocks 402 is five, one of which is located in the middle of the top plate 401, and the other four plug-in blocks 402 are arranged circumferentially on the top plate 401. A generator 403 is arranged in the middle of the upper surface of the top plate 401, and the generator 403 is plugged into the top plate 401.

[0042] The working process of this embodiment is as follows: the staff carries the storage unit 100 to the location to be installed, and then installs the support unit 200 according to the wind direction of the environment. When it is necessary to detect the wind and sand content under a relatively complex wind direction environment, by placing multiple support units 200 on the upper surface of the storage unit 100, the sand collecting unit 300 faces different directions, so that the sand can be collected in all directions. In this process, the sand content in the wind and sand flow is detected by comprehensively calculating the weight of the collected sand. When it is necessary to detect the wind and sand content in the air at different heights, multiple support units 200 are stacked and then fixed by the fixing unit 400. After the sand collecting unit 300 collects the sand, in this process, the weight of the sand in the sand collecting bucket 307 is weighed respectively by the weight sensor 306, so as to detect the sand content in the air at different heights. Under the action of the controller, the weight of the sand in the sand collecting bucket 307 is detected regularly by the weight sensor 306.

[0043] Although embodiments of the present invention 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 invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
