Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and more specifically, to an automatic weighing multi-directional sand collector. Background Technology

[0002] Wind is one of the fundamental stresses shaping landforms, especially in arid climates where it becomes a major driving force determining desert surface morphology. It exacerbates desertification, sand dune migration, soil erosion, and the formation of wind-eroded surfaces in the Gobi Desert. In recent years, sandstorms, a significant indicator of wind and sand activity, have severely impacted my country's environment, socio-economic stability, and international image, making the control of various wind and sand disasters an urgent priority. Furthermore, global climate change is leading to increasingly severe desertification and more frequent sandstorms, drawing significant attention. Particularly in areas severely affected by wind and sand, where the ecological environment is extremely harsh, the task of sand control is crucial to ensuring the safety of major projects, such as road construction in desert oil and gas field development and the working environment in development zones. Therefore, before establishing sand control systems along roadsides, it is essential to monitor field wind and sand flow data.

[0003] Most sand collectors currently in use are single-direction and cannot reflect changes in direction simultaneously. Furthermore, traditional sand collectors often suffer from poor continuity of observation. Data acquisition requires manual timing and weighing, resulting in low automation, cumbersome operation, and high labor costs. Moreover, it is difficult to establish a correlation between sand flux measurement results and wind speed and direction, leading to poor usability and significant inconvenience for sand control and desertification prevention efforts.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] 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.

[0033] In existing technologies, sand collectors can only collect sand blown from one direction. When it is necessary to collect sand blown from multiple directions, multiple sand collectors need to be configured, which is costly. Moreover, each sand collector operates independently, requiring manual sand collection and weighing, which is labor-intensive, prone to errors, and results in poor accuracy.

[0034] In view of this, the designers have provided an automatic weighing multi-directional sand collector that can simultaneously collect sand from multiple directions. It is powerful, reduces the number of sand collectors, and lowers costs. In addition, the weight of the sand is automatically weighed, reducing labor intensity and improving data accuracy.

[0035] Please refer to Figures 1-5 ,in, Figure 1 To illustrate the internal structure, a portion of the base 100 has been cut open. This embodiment provides an automatic weighing multi-directional sand collector, including a base 100 and multiple sand collection units 200, wherein:

[0036] The base 100 is used to fix it to the stratum; each sand collection unit 200 includes a sand collection cylinder 210, a sand collection box 220 and a weighing sensor 230, and the sand collection cylinder 210, the sand collection box 220 and the weighing sensor 230 are all installed on the base 100; the sand collection cylinder 210 is provided with a sand falling channel 216 and an air inlet 213, an air outlet 214 and a sand falling outlet 215 that are all connected to the sand falling channel 216; multiple sand collection cylinders 210 are arranged at intervals in the circumference of the base 100, and multiple air inlets 213 have different orientations; the sand falling outlet 215 is connected to the sand collection box 220; the sand collection box 220 is placed on the weighing sensor 230.

[0037] As described above, the working principle of the automatic weighing multi-directional sand collector in this embodiment is as follows:

[0038] In use, the base 100 is fixed to the ground, with the height of the air inlet 213 roughly flush with the ground level. Since multiple sand collection cylinders 210 are installed on the base 100, each with its air inlet 213 facing a different direction, when wind blows from different directions, sand particles carried by the wind can enter the sand collection cylinder 210 through the corresponding air inlet 213. The wind blows out from the air outlet 214, leaving the sand particles inside the sand collection cylinder 210. The sand then falls along the sand drop channel 216 and into the sand collection box 220 from the sand drop outlet 215. The sand collection box 220 is placed on a weighing sensor 230. The weight of the sand particles in the sand collection box 220 is automatically acquired by the weighing sensor 230, and the weight parameters acquired by the weighing sensor 230 can be transmitted to a smart terminal in real time for storage. This data is less likely to be lost and facilitates data analysis and processing through the smart terminal, thus providing reliable data for wind and sand environment monitoring.

[0039] It should be understood that smart terminals can be computers, mobile phones, tablets, or data acquisition devices such as 300.

[0040] The details of the automatic weighing multi-directional sand collector according to the embodiments of this application are described by way of example.

[0041] Please combine Figure 1In this embodiment, optionally, the automatic weighing multi-directional sand collector includes a base 100, eight sand collection units 200, a data acquisition unit 300, and a power supply module 400. The base 100 is used to position itself on the stratum. The eight sand collection units 200 are evenly spaced around the base 100 along a vertically extending axis. The data acquisition unit 300 and the eight sand collection units 200 can communicate with each other via wires 500 or wirelessly. The power supply module 400 can communicate with the data acquisition unit 300 via wires 500.

[0042] It should be understood that in other embodiments, the number of sand collection units 200 is not limited to eight. Furthermore, the power supply module 400 can be a solar photovoltaic power generation module, etc. The power supply module 400 can power all the weighing sensors 230 and data acquisition devices 300, saving energy. Obviously, in other embodiments, the automatic weighing multi-directional sand collector can also be equipped with a built-in battery for power supply; the battery can be installed inside the base 100.

[0043] Please combine Figure 1 In this embodiment, optionally, the base 100 includes a bottom shell 110 and a top cover 120. The bottom shell 110 has a device cavity, the top of which is open. The top cover 120 is installed on the bottom shell 110 and is used to open or close the opening. The bottom shell 110 can be a circular shell, with its top closed and a circular opening. The top cover 120 is a circular plate, with a diameter larger than the outer diameter of the bottom shell 110. The top cover 120 can be fixed to the top of the bottom shell 110 by a snap-fit ​​mechanism, and the top cover 120 and the bottom shell 110 can be detached. Because the diameter of the top cover 120 is larger than that of the bottom shell 110, the edges of the top cover 120 extend beyond the perimeter of the bottom shell 110. When the bottom shell 110 is buried in the stratum, the top cover 120 can serve as a reference for the burial depth, with the burial position approximately where the top cover 120 is in contact with the surface of the stratum.

[0044] In addition, a fixing hole 121 can be provided on the top cover 120 for the fixing rod to pass through, and the fixing rod can be inserted into the ground to improve the stability of the base 100.

[0045] Meanwhile, the top cover 120 is provided with eight assembly holes, all of which connect to the equipment cavity. The number of assembly holes should be equal to the number of sand collection units 200.

[0046] In this embodiment, optionally, the eight sand collection units 200 are configured with the same structure. To avoid repetition and redundancy, the structure of one sand collection unit 200 will be used as an example for explanation.

[0047] Please combine Figures 1-4Optionally, each sand collection unit 200 includes a sand collection cylinder 210, a sand collection box 220, and a weighing sensor 230. The sand collection cylinder 210, sand collection box 220, and weighing sensor 230 are all mounted on the base 100. The sand collection cylinder 210 is provided with a sand discharge channel 216 and an air inlet 213, an air outlet 214, and a sand discharge port 215, all connected to the sand discharge channel 216. Eight sand collection cylinders 210 are arranged at intervals around the circumference of the base 100. The eight air inlets 213 face different directions, corresponding to the eight directions: east, west, south, north, southeast, northeast, southwest, and northwest. The sand discharge port 215 communicates with the sand collection box 220; the sand collection box 220 is placed on the weighing sensor 230.

[0048] During assembly, the sand collection cylinder 210 is installed on the top cover 120 and inserted into the corresponding assembly hole. In the arrangement direction of the eight sand collection cylinders 210, the edges of any two adjacent sand collection cylinders 210 are joined together. For example, two adjacent sand collection cylinders 210 can use a concave-convex structure for interlocking, resulting in high sealing at the connection point and preventing air leakage. The load cell 230 is installed on the bottom shell 110, and the sand collection box 220 is placed on the corresponding load cell 230. All load cells 230 can be connected to the data acquisition unit 300 via a wiring harness, or the load cells 230 can be connected to the data acquisition unit 300 wirelessly. For example, the load cells 230 and the data acquisition unit 300 can be wirelessly connected via Wi-Fi or Bluetooth.

[0049] Optionally, the sand collecting cylinder 210 includes a cylinder body 211 and a discharge nozzle 212. The air inlet 213 and the air outlet 214 are both opened on the cylinder wall of the cylinder body 211, and the cylinder cavity of the cylinder body 211 forms a sand discharge channel 216. The discharge nozzle 212 protrudes from the bottom of the cylinder body 211, and the sand discharge port 215 is set on the discharge nozzle 212. The discharge nozzle 212 is provided with an inclined guide wall, which is used to guide the sand particles to the sand discharge port 215.

[0050] In addition, there are two discharge nozzles 212, and the sand discharge openings 215 on the two discharge nozzles 212 are arranged opposite each other. The angle α between the guide wall of each discharge nozzle 212 and the horizontal plane can be set to 25-35°, which facilitates the sliding of sand particles and reduces the impact of wind on the sand particles in the sand collection box 220.

[0051] Optionally, the cylinder 211 includes a top plate, a bottom plate, a first side plate, a second side plate, a third side plate, and a fourth side plate. The first, second, third, and fourth side plates are connected end-to-end in sequence. Both the top plate and the bottom plate are simultaneously connected to the first, second, third, and fourth side plates. The discharge nozzle 212 is located on the outside of the bottom plate. The air inlet 213 is located on the first side plate, and the air outlet 214 is located on the third side plate. The first and third side plates are opposite each other, with the first side plate located on the outside and the third side plate located on the inside. Simultaneously, the distance between the second and fourth side plates gradually increases from the first side plate towards the third side plate. In other words, the cross-sectional profile of the cylinder 211 perpendicular to its length is approximately an isosceles trapezoid, resulting in high structural strength. The second and fourth side plates have air guiding functions and a long service life.

[0052] It should be noted that when the sand collection cylinder 210 is inserted into the corresponding mounting hole on the top cover 120, the air inlet 213 and the air outlet 214 are both located above the top cover 120, and the sand drop outlet 215 is located below the top cover 120. At the same time, the sand collection box 220 and the weighing sensor 230 are both located inside the equipment cavity.

[0053] In this embodiment, optionally, the sand collection unit 200 further includes a sand-blocking net 240. The sand-blocking net 240 is installed on the sand collection cylinder 210 and covers the area enclosed by the air outlet 214. The sand-blocking net 240 is used to block sand particles carried by the wind. When sand is blown in from the air inlet 213, the sand particles are blocked by the sand-blocking net 240 and are not easily carried away from the sand collection cylinder 210 by the wind. The wind can then be quickly discharged from the air outlet 214, and is less likely to affect the sand particles in the sand collection box 220.

[0054] Optionally, the sand collection cylinder 210 is provided with an installation slot, and the sand-blocking net 240 is detachably snapped into the installation slot. When the sand-blocking net 240 needs to be replaced, the sand-blocking net 240 is pulled off the sand collection cylinder 210, and then a new sand-blocking net 240 is inserted into the sand collection cylinder 210, which is convenient to operate.

[0055] The operating principle of the automatic weighing multi-directional sand collector provided in this embodiment is as follows:

[0056] First, a pit is dug at the selected measurement location. The bottom of the pit is leveled using a level. If the sand and gravel particles are large and difficult to level, a flat plate is placed at the bottom of the pit. The base 100 is placed in the pit, and a fixing rod is driven through the top cover 120 and nailed below the ground surface, with the lower surface of the top cover 120 almost touching the ground surface. Air is blown in through the air inlet 213 and out through the air outlet 214. The sand particles in the air are blocked by the sand-blocking net 240 and fall directly into the sand collection box 220 through the sand drop channel 216 and the sand outlet. During monitoring, the data acquisition instrument 300 is turned on and the data on the data acquisition instrument 300 is zeroed. The weighing sensor 230 obtains the weight signal, which is transmitted to the data acquisition instrument 300 through the wire 500. The data acquisition instrument 300 can automatically record the weight of the sand at regular intervals. The computer program used in the operation of the weighing sensor 230 and the data acquisition instrument 300 can be obtained by those skilled in the art from the prior art.

[0057] The automatic weighing multi-directional sand collector provided in this embodiment can simultaneously collect sand from multiple directions and automatically weigh the sand particles, offering diverse functions.

[0058] 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.
