Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to a multifunctional gradient sand collector. Background Technology

[0002] In severely desertified areas, wind erosion frequently occurs due to the force of wind. Therefore, scientific monitoring and in-depth research on wind erosion are essential for exploring and proposing countermeasures against desertification. Studying wind erosion requires appropriate collection instruments. Currently, various types of wind erosion collection devices have been developed both domestically and internationally, such as flat-mouth sand collectors, multi-channel square-mouth sand collectors, and tipping bucket sand collectors. However, these devices all have limitations. Some can only collect sand transport flux from one direction, making it difficult to accurately reflect the true wind erosion situation. Others can collect wind erosion flux from different directions but do not collect by direction. Furthermore, field sand collectors are mostly manually collected, resulting in inaccurate collection times and significant errors. Most sand collectors also do not consider the loss or increase of sand volume due to rainwater, failing to accurately reflect sand transport conditions in all directions. Moreover, most of these sand collectors only collect wind erosion data from the surface 0-20cm, failing to reflect vertical changes in wind erosion flux.

[0003] The inventors discovered during their research that existing sand collection devices have at least the following drawbacks:

[0004] Traditional wind erosion collection equipment has relatively simple functions and its own limitations. It cannot complete the sampling work well during use, which greatly restricts data collection. Utility Model Content

[0005] The purpose of this invention includes, for example, providing a multifunctional gradient sand collector that can reduce the impact of rainfall on sand collection results, improve the accuracy of monitoring results, and achieve gradient sand collection, thus offering diverse functions.

[0006] The embodiments of this utility model can be implemented as follows:

[0007] Firstly, this utility model provides a multifunctional gradient sand collector, including a support base, multiple sand collecting devices, and multiple rainproof devices, wherein:

[0008] The support base is used for installation on the ground surface;

[0009] The multiple sand collection devices are all connected to the support base and are stacked in the extension direction of the preset axis;

[0010] The multiple rainproof devices are connected one-to-one with the multiple sand collection devices, and each rainproof device is located above the corresponding sand collection device.

[0011] In an optional embodiment, the support base includes a chassis, a support tube, and a counterweight. The support tube and the counterweight are both fixed to the chassis, which is used for installation on the ground surface. The plurality of sand collection devices are all sleeved on the support tube, and the length direction of the support tube is consistent with the preset axis direction.

[0012] In an optional embodiment, the sand collection device includes a collector and a sand collection container. The collector has multiple sand collection channels arranged at intervals along its outer circumference. Each sand collection channel has an air inlet, an air outlet, and a sand drop outlet. The air inlet and the sand drop outlet are arranged along the extension direction of the sand collection channel, with the air inlet located outside the sand drop outlet. The sand collection container is connected to the collector and is used to collect sand falling from the sand collection channels. Both the collector and the sand collection container are fitted onto the support pipe, with the sand collection container connected to the support pipe. A rainproof device is fitted onto the support pipe.

[0013] In an optional embodiment, the collector includes an annular top plate, an annular bottom plate, and multiple partitions. The annular top plate and the annular bottom plate are arranged opposite each other at intervals. The multiple partitions are all installed between the annular top plate and the annular bottom plate. The multiple partitions are arranged at intervals in the circumferential direction of the annular top plate or the annular bottom plate. The annular top plate, the annular bottom plate, and the adjacent partitions cooperate to define a sand collection channel. The sand collection container is connected to the annular bottom plate and located below the annular bottom plate. The rainproof device is connected to the annular top plate, and the two are spaced apart in the axial direction of the support pipe. The annular top plate and the annular bottom plate are both sleeved on the outside of the support pipe, and the annular bottom plate and the support pipe have an annular gap.

[0014] In an optional embodiment, the air outlet is located on the annular top plate;

[0015] The collector also includes a sand-blocking net connected to the annular top plate and covering the air outlet to allow only air to pass through.

[0016] In an optional embodiment, the collector further includes a guide tube, one end of which is mounted on the annular base plate and the other end of which extends into the annular gap and faces the sand collection container. The inner diameter of the guide tube gradually decreases in the direction from the annular base plate toward the sand collection container. The guide tube is used to guide sand from the annular gap into the sand collection container.

[0017] In an optional embodiment, the rainproof device includes a rainproof canopy and a support column. The rainproof canopy is fixed above the collector by the support column. The rainproof canopy is sleeved on the outside of the support tube, and the rainproof canopy and the collector are spaced apart in the length direction of the support tube.

[0022] In summary, the multifunctional gradient sand collector provided in this embodiment, by installing multiple sand collection devices spaced apart along a preset axis on a support base, allows each sand collection device to collect sand independently. When in use, the multiple sand collection devices are arranged vertically, and each device can collect sand from different heights and directions, achieving gradient multi-directional sand collection. This enables comprehensive monitoring of wind and sand activity and improves the accuracy of monitoring results. Furthermore, since each sand collection device is equipped with a rainproof device, it can block rainwater from entering the sand collection device, reducing the probability of inaccurate observation data due to rainwater factors.

[0037] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] In the existing technology, there are various types of sand collectors. Some sand collectors can achieve multi-directional sand collection, but they cannot achieve gradient sand collection. Moreover, most sand collectors are easily affected by rainwater in terms of measurement results.

[0040] In view of this, the designers have provided a multi-functional gradient sand collector, which can not only collect wind and sand from multiple gradients and directions, but also reduce the adverse effects of rainwater on the monitoring results. It has multiple functions and the monitoring results are accurate and reliable.

[0041] Please refer to Figures 1-6 This embodiment provides a multifunctional gradient sand collector, including a support base 100, multiple sand collecting devices 200, and multiple rainproof devices 300, wherein:

[0042] Support base 100 is used for installation on the ground surface;

[0043] Multiple sand collection devices 200 are connected to the support base 100 and are stacked in the extension direction of the preset axis 001;

[0044] Multiple rainproof devices 300 are connected one-to-one with multiple sand collection devices 200, and each rainproof device 300 is located above the corresponding sand collection device 200.

[0045] As described above, the multifunctional gradient sand collector provided in this embodiment is used as follows:

[0046] The support base 100 is placed on the ground, and auxiliary fixing devices can be used to improve the stability of the support base 100 and prevent it from tipping over or tilting. Multiple sand collection devices 200 are arranged vertically at intervals, each at a different height. In use, each sand collection device 200 can collect sand independently, while the multiple devices arranged vertically can collect sand from different heights and directions, achieving gradient multi-directional sand collection and enabling comprehensive monitoring of wind and sand activity, thus improving the accuracy of monitoring results. Simultaneously, since each sand collection device 200 is equipped with a rainproof device 300, it can block rainwater and prevent rainwater from entering the sand collection box 224, reducing the probability of inaccurate observation data due to rain.

[0047] The following embodiments illustrate the details of the multifunctional gradient sand collector of this application by way of example.

[0048] Please refer to Figures 1-6 In this embodiment, optionally, the multifunctional gradient sand collector includes a support base 100, four sand collecting devices 200, four rainproof devices 300, a solar power supply device 400, and a processor 500. The four sand collecting devices 200 are all fixed to the support base 100 and are evenly spaced along the extension direction of a preset axis 001. The four rainproof devices 300 correspond one-to-one with the four sand collecting devices 200, with each rainproof device 300 installed above its corresponding sand collecting device 200. The solar power supply device 400 supplies power to the processor 500 and the sand collecting devices 200, among other electrical components.

[0049] It should be understood that in some embodiments, the number of sand collection device 200 and rainproof device 300 is not limited to four; the number of both can be equal and designed as needed.

[0050] Please refer to Figure 1 Optionally, the support base 100 includes a chassis 110, a support tube 120, and a counterweight. Both the support tube 120 and the counterweight are fixed to the chassis 110, which is used for installation on the ground surface. Multiple sand-collecting devices 200 are sleeved around the support tube 120, and the length direction of the support tube 120 is aligned with the preset axis 001. By making the support tube 120 a hollow tube with internal channels, it facilitates the laying of power lines and other wiring.

[0051] In addition, four connecting plates 130 can be installed on the support pipe 120, and the four connecting plates 130 are respectively connected to four collection devices. Furthermore, the top of the support pipe 120 is sealed to prevent rainwater from entering.

[0052] It is worth noting that the four sand collection devices 200 can be designed to have the same structure. In this embodiment, in order to avoid repetition and redundancy, the structure of one sand collection device 200 will be described.

[0053] Please refer to Figures 1-3 Optionally, the sand collection device 200 includes a collector 210, a sand collection container 220, and a guide cylinder 230. Both the collector 210 and the sand collection container 220 can be mounted on the support pipe 120. The guide cylinder 230 is mounted on the collector 210 and guides the sand into the sand collection box 224. Simultaneously, multiple sand collection channels 211 are provided on the outer circumferential surface of the collector 210. These channels are arranged at intervals around the collector 210; for example, there are 16 sand collection channels 211, allowing the collection of sand from 16 directions. Each sand collection channel 211 has an air inlet 2111, an air outlet 2113, and a sand drop outlet 2112. The air inlet 2111 and the sand drop outlet 2112 are arranged along the extension direction of the sand collection channel 211, with the air inlet 2111 located outside the sand drop outlet 2112. The sand collection container 220 can be installed below the collector 210. The sand collection container 220 is used to collect sand falling from the sand collection channel 211.

[0054] Specifically, the collector 210 includes an annular top plate 212, an annular bottom plate 213, multiple partitions 214, and multiple sand-blocking nets 215. The annular top plate 212 and the annular bottom plate 213 can both be regular polygonal plates or circular plates, etc. The annular top plate 212 and the annular bottom plate 213 are arranged at intervals relative to each other in the extension direction of the preset axis 001. Multiple partitions 214 are installed between the annular top plate 212 and the annular bottom plate 213. The multiple partitions 214 are arranged at intervals in the circumferential direction of the annular top plate 212 or the annular bottom plate 213. The annular top plate 212, the annular bottom plate 213, and the adjacent partitions 214 cooperate to define a sand collection channel 211. Meanwhile, multiple baffles 214 are arranged radially around a preset axis 001, meaning that the length direction of the baffles 214 is basically consistent with the radial direction of the annular top plate 212 or the annular bottom plate 213. This results in a large outer opening and a small inner opening in the sand collection channel 211, with the air inlet 2111 located on the outer side and the sand drop outlet 2112 located on the inner side, facilitating the entry of wind and sand into the sand collection channel 211. Simultaneously, the air outlet 2113 is located on the annular top plate 212, and its shape is similar to that of the sand collection channel 211. Multiple sand-blocking nets 215 are installed on the annular top plate 212, with each net blocking a corresponding air outlet 2113. The size of the gaps in the sand-blocking nets 215 is designed as needed, allowing wind to pass through while blocking sand.

[0055] Furthermore, the sand collection container 220 is connected to the annular base plate 213 by bolts 140 and is located below the annular base plate 213. The guide cylinder 230 is installed on the inner edge of the annular base plate 213, and the two are coaxially arranged. The support pipe 120 passes through the annular top plate 212, the annular base plate 213, and the guide cylinder 230. The annular top plate 212 can be fixedly connected to the corresponding connecting plate 130 on the support pipe 120 by bolts 140, etc. The guide cylinder 230 and the support pipe 120 have an annular gap, so that sand falling from the annular base plate 213 can enter the guide cylinder 230 through the annular gap and then enter the sand collection container 220. Obviously, since the guide cylinder 230 is located on the inner edge of the annular base plate 213, it indicates that an annular gap is formed between the inner edge of the annular base plate 213 and the support pipe 120.

[0056] Furthermore, the guide cylinder 230 is a circular cylinder. One end of the guide cylinder 230 is installed on the annular base plate 213, and the other end of the guide cylinder 230 extends between the annular base plate 213 and the support pipe 120 and faces the sand collection container 220. The inner diameter of the guide cylinder 230 gradually decreases in the direction from the annular base plate 213 toward the sand collection container 220. The guide cylinder 230 is used to guide sand from the annular gap into the sand collection container 220.

[0057] Please combine Figure 7 Optionally, the sand collection container 220 includes a shell 221, a circuit board 222, a weighing sensor 223, and a sand collection box 224. The shell 221 is fixed below the annular base plate 213. The weighing sensor 223 is fixed on the circuit board 222, which is fixed inside the shell 221. The sand collection box 224 is placed on the weighing sensor 223. The support tube 120 passes through the shell 221 and the sand collection box 224, and the shell 221 can be fixedly connected to the support tube 120. Multiple weighing sensors 223 can be arranged evenly around the support tube 120. The circuit board 222 can be electrically connected to the processor 500 via a power cord. The power cord can pass through a through hole 121 on the wall of the support tube 120 and be installed inside the support tube 120.

[0058] It should be understood that the sand collection box 224 can be configured as a ring structure with a ring-shaped sand collection groove 225, into which sand from multiple directions can fall. Furthermore, the height of the top edge of the inner cylinder wall 2241 of the sand collection box 224 is not lower than the height of the top of the sand drop outlet 2112, effectively collecting sand. To prevent sand from entering the gap between the outer shell 221 and the support pipe 120, a mesh 226 can be installed between the ring-shaped top plate 212 and the inner cylinder wall 2241. The bottom of the mesh 226 is connected to the inner cylinder wall 2241, and its top is spaced from the ring-shaped top plate 212, allowing only wind to pass through.

[0059] Please refer to Figure 4 In this embodiment, optionally, the rainproof device 300 includes a rainproof canopy 310 and a support column 320. The rainproof canopy 310 is fixed above the annular top plate 212 of the collector 210 by the support column 320. The rainproof canopy 310 is sleeved on the outside of the support tube 120. The rainproof canopy 310 and the annular top plate 212 have a gap in the length direction of the support tube 120, so that wind can be blown out from the air outlet 2113 on the annular top plate 212.

[0060] It should be understood that there can be multiple support columns 320, which can be arranged around the support tube 120. The multiple support columns 320 work together to support the rain shelter 310, resulting in good support. The support tube 120 passes through the rain shelter 310, and a sealing ring is provided between the support tube 120 and the rain shelter 310 to improve rainproof performance.

[0061] Optionally, the top surface of the rain shelter 310 is set as a cone shape, with the center of the cone being higher than the surrounding edges, which facilitates the flow of rainwater along the cone surface and provides good drainage.

[0062] In some embodiments, the rain shelter 310 can be designed as a split structure, comprising a central annular plate and multiple trapezoidal plates around the perimeter. The multiple trapezoidal plates are sequentially spliced ​​to form an annular structure, with the annular plate located in the middle of the trapezoidal plates, and the annular plate and each trapezoidal plate are sealed together. The annular plate can be fixed above the connecting plate 130 by bolts 140.

[0063] The instruction manual indicates that the solar power supply device 400 includes a photovoltaic panel assembly 410 and a battery 420. The photovoltaic panel assembly 410 is connected to the battery 420 via a power cord. The battery 420 is connected to the processor 500. The processor 500 is connected to the circuit boards 222 of all the sand collection devices 200 via power cords. For ease of wiring, a cable outlet is provided on the wall of the support pipe 120, through which the power cord connecting the circuit board 222 and the processor 500 exits.

[0064] Please refer to Figure 6 In other embodiments, optionally, each sand collection device 200 also includes an acoustic intelligent sensing system. This system can acquire the weight of the sand, replacing the method of using a weighing sensor 223. Obviously, there are various methods for acquiring the sand weight; manual weighing can also be used, and the appropriate method can be chosen as needed. Optionally, the acoustic intelligent sensing system includes an acoustic amplifier 600 and a wind speed sensor 700. Both the acoustic amplifier 600 and the wind speed sensor 700 are installed inside each sand collection channel 211 and are electrically connected to the processor 500. A battery 420 can power the acoustic intelligent sensing system.

[0065] In this equation, the number of wave crests y in the acoustic spectrum is equal to the number of sand grains x, and the energy Q of a single sand grain is positively correlated with the amplitude A of a single wave crest. The formula for calculating the mass m of a single sand grain is: m = Q / v, where v is the velocity of the sand grain, and the velocity of the wind-blown sand flow is equal to the velocity of the sand grain; the formula for calculating the total mass M of the sand grains is: M = m1 + m2 + ... + m n In the formula, m1, m2…m n Let be the masses of the nth grain of sand.

[0066] The multifunctional gradient sand collector provided in this embodiment has diverse functions and collects highly accurate data.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
