Description

Technical Field

[0001] The present invention belongs to the technical field of observation equipment, and in particular relates to an omnidirectional sand accumulation collection component, a full-automatic sand accumulation instrument, and a use method and application thereof. Background Art

[0002] The sediment transport rate is the sediment transported per unit area (cm2) perpendicular to the wind direction per unit time (s). 2 ) is the mass of the flowing sand (g), which is the most important parameter to measure the intensity characteristics of the wind-sand flow and occupies an important position in the field of wind-sand physics research.

[0003] At present, there are many types of field sand accumulation meters for collecting sand transport. From the perspective of the direction of collecting sand transport, there are single-direction, four-direction, eight-direction, and sixteen-direction field fixed sand accumulation meters and rotatable all-round sand accumulation meters using bearings and wind deflector systems; from the perspective of data collection methods, there are those that obtain sand accumulation through regular manual collection and weighing, and those that automatically record sand accumulation through electronic scales and data acquisition instruments. Although by using these previous devices, researchers have revealed the laws of sand movement under various underlying surfaces and wind conditions, and provided a lot of important information about the characteristics of field sand flow, there are also important defects. For example, the most advanced one currently used is the all-round automatic sand accumulation meter, a typical representative of which is the fourth-generation CWHF fully automatic sand accumulation meter produced by Huayirui Company. Its main defects are as follows:

[0004] First of all, this sand accumulation meter uses a fixed four-directional opening to collect sand blowing in from all directions, weigh it with an electronic scale, and record the data. However, there are inevitably four pillars at the opening, which block the sand blowing in from these four directions, so the data is smaller than the actual value, and it is not a fully omnidirectional sand accumulation meter; in addition, since most of the wind and sand transmission is concentrated within 20cm height near the ground, this range is the key area for monitoring sand transport, but due to the small size of the sand accumulation meter, the maximum sand capacity is only a few hundred grams. In field observations in the Kumtag Desert in Dunhuang, we found that the sand transport intensity at a height of 10cm can reach 2kgcm -2 d -1 Therefore, this type of sand accumulation instrument will be filled with sand and become ineffective in a few hours or even minutes under a strong sand transport environment. Especially when monitoring the amount of sand transport near the ground, it does not have high weather resistance and practicality. Therefore, the relevant research on the movement process of wind and sand flow under a strong sand transport environment is limited.

[0005] There are also two serious defects in the truly rotatable all-round sand accumulation meter using the bearing and wind deflector system. First, since the inner and outer rings of the bearing are relatively rotating components with gaps, the gap between the inner and outer rings cannot be absolutely sealed under the premise of ensuring flexible rotation, and the sand and dust will enter this gap with the airflow. Even if imported sealed bearings are used, the bearings will not rotate properly, and the wind deflector connected to it and controlling the direction will not be able to rotate flexibly with the wind, and then the sand accumulation port cannot face the direction of the wind, resulting in incorrect sand accumulation data and unusable data. Therefore, the current all-round sand accumulation meter that uses bearings and wind deflectors to achieve steering generally has a normal use period of no more than three months in desert areas with strong sand transport environments, and the bearing rotation will be blocked, resulting in incorrect sand accumulation data and unusable data. At this time, the bearing needs to be replaced; in addition, the salt and alkali content in the surface and atmosphere of the desert area is relatively high, and salt spray crystallization will also cause the bearing to rotate improperly, thereby invalidating the sand accumulation meter data.

[0006] Therefore, avoiding the influence of dust and salt mist crystallization on the bearings, protecting the bearings, ensuring that the bearings can rotate flexibly for a long time, and always aligning the sand accumulation port with the wind direction are key technical issues for all-round sand accumulation instruments to collect reliable sand accumulation data. In addition, in order to avoid data being invalidated after full sand accumulation and to achieve long-term maintenance-free, large-capacity sand accumulation buckets and high-range electronic scales must be used. However, the accuracy of high-range electronic scales is poor and cannot meet the needs of collecting trace sand delivery data at a frequency of 1Hz. This is also a serious defect or contradiction faced by all sand accumulation instruments. Summary of the invention

[0007] The main purpose of the present invention is to provide an omnidirectional sand accumulation collection component, a fully automatic sand accumulation instrument and a sand delivery collection method thereof, so as to overcome the deficiencies existing in the prior art.

[0008] To achieve the above-mentioned purpose, the technical solution adopted by the embodiment of the present invention includes:

[0009] An embodiment of the present invention provides an all-round sand collection assembly, which includes a connecting pipe, a sealed bearing, a sealed bearing wrapping component and a sealing cover, wherein the sealed bearing is sleeved on the connecting pipe, the sealed bearing is arranged in the sealed bearing wrapping component, the sealing cover is also sleeved on the connecting pipe and is sealedly combined with the connecting pipe and the sealed bearing wrapping component to form a sealed chamber, and the sealed bearing is arranged in the sealed chamber; a collection nozzle for collecting sand is also provided at one end of the connecting pipe, and an air guide plate is also connected to the connecting pipe.

[0010] Furthermore, the omnidirectional sand accumulation collection assembly also includes a sealing gasket, which is combined with one end of the sealing bearing wrapping component, and the other end of the sealing bearing wrapping component is used to connect with the top cover of the full-automatic sand accumulation instrument body.

[0011] Furthermore, the sealing cover includes a stainless steel threaded sealing cover and a rubber sleeve sealed sealing cover, both of which are sealed connected to the connecting pipe and the sealed bearing wrapping component, and the stainless steel threaded sealing cover is encapsulated in a sealed space formed by the rubber sleeve sealed sealing cover and the sealed bearing wrapping component.

[0012] Furthermore, the collecting nozzle comprises a pointed-mouth collecting nozzle or a wide-mouth collecting nozzle.

[0013] An embodiment of the present invention also provides a fully automatic sand accumulation meter, which includes a fully automatic sand accumulation meter main body and an all-round sand accumulation collection component connected to the fully automatic sand accumulation meter main body, the fully automatic sand accumulation meter main body includes an outer barrel and an inner barrel arranged in the outer barrel, the inner barrel is used to store sand collected by the all-round sand accumulation collection component, and the inner barrel includes a main inner barrel and an inner and outer two-layer structure that are independently arranged from each other, the main inner barrel and the auxiliary inner barrel are respectively matched with a main electronic scale and an auxiliary electronic scale, and a connecting section is also provided at the top edge of the main inner barrel, and excess sand in the main inner barrel can automatically flow into the auxiliary inner barrel through the connecting section under the action of gravity, and the connecting section has no contact with the auxiliary inner barrel.

[0014] In the embodiment of the present invention, the auxiliary inner barrel adopts an inner and outer double-layer structure, so that the sand overflowing from the main barrel has no effect on the auxiliary electronic scale.

[0015] Furthermore, one end of the connecting section is connected to the top edge of the main inner barrel, and the other end extends to the center position of the top of the auxiliary inner barrel.

[0016] Furthermore, the arc length of the connection between the connecting section and the main inner barrel is 1 / 16 of the circumference of the top of the main inner barrel.

[0017] Furthermore, a conical top cover is buckled on the top of the outer barrel, and the omnidirectional sand collection assembly is connected to the conical top cover.

[0018] The embodiment of the present invention further provides a method for collecting the amount of sand transported based on the aforementioned fully automatic sand accumulation instrument, which comprises the following steps:

[0019] (1) First, the sand is accumulated in the main inner barrel. The wind-blown sand particles all fall into the main inner barrel through the omnidirectional sand collection component. The main electronic scale, data collector and remote transmission system are used to weigh, record and transmit the sand weight data to the user terminal.

[0020] (2) Secondly, sand is accumulated in the secondary inner barrel. When the main inner barrel is full of sand, the data of the main electronic scale will remain unchanged, and the sand will flow down from the top edge of the main inner barrel through the connecting section of the main inner barrel and the secondary inner barrel, and 1 / 16 of the amount of sand flowing out will fall into the secondary inner barrel. The real-time change data of the accumulated sand volume is monitored through the secondary electronic scale, data acquisition device and remote transmission system. The value of the secondary electronic scale is multiplied by 16 and then added to the full load mass of the main inner barrel to obtain the real-time dynamic change data of the total accumulated sand volume;

[0021] (3) According to the actual situation of wind and sand intensity in the field, 0.5, 1, 1.5 or 2 years are selected as the maintenance cycle. That is, when the user terminal encounters data interruption or the data remains unchanged for a long time during data collection, the automatic sand accumulation meter is maintained.

[0022] Correspondingly, an embodiment of the present invention also provides a method for calculating the starting wind speed of sand particles, which includes: setting a wind erosion sensor at a height of 5 cm, which is a standard height for calculating the starting wind speed of sand particles, with a recording frequency of 1 Hz, and obtaining the number and impact kinetic energy data of wind-eroded sand particles per unit area at a height of 5 cm through the wind erosion sensor; and obtaining the mass data of wind-eroded sand particles per unit area at a height of 5 cm through the aforementioned fully automatic sand accumulation meter, that is, the sand transport data, with a recording frequency of 1 Hz, and then calculating the starting wind speed of sand particles; the result can be compared and verified with the starting wind speed value calculated by the wind erosion sensor data, providing a new calculation method for obtaining the starting wind speed of sand particles.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The omnidirectional sand collection assembly of the present invention provides multi-layer protection for the bearings, which effectively solves the problem that the bearings are easily blocked by sand and dust, resulting in poor rotation and invalid data. In addition, in a strong sand transport environment, the sand accumulation port can keep rotating with the wind for a long time and align with the incoming wind direction, effectively improving the reliability of the sand transport data.

[0025] (2) The omnidirectional sand collection component of the present invention has a replaceable collection nozzle, which can be flexibly used according to the intensity of outdoor wind and sand. The omnidirectional sand collection component is divided into a pointed nozzle type and a wide nozzle type. The pointed nozzle type is suitable for super strong sand transport environment, and the wide nozzle type is suitable for strong sand transport environment.

[0026] (3) The fully automatic sand accumulation meter of the present invention is designed by combining the auxiliary inner barrel, the auxiliary electronic scale with the main inner barrel and the main electronic scale, thereby avoiding the disadvantage of poor data accuracy caused by the use of a high-range electronic scale for large sand accumulation, and realizing the data collection of the sand accumulation meter at a high frequency of 1 Hz. When the main inner barrel is full of sand, the data of the main electronic scale will remain unchanged, and the sand will flow down from the top edge of the main inner barrel, and 1 / 16 of the amount of the flowing sand will fall into the auxiliary inner barrel. At this time, a low-range, high-precision auxiliary electronic scale is used to monitor the real-time change of the sand accumulation. In the later processing, the value of the auxiliary electronic scale is multiplied by 16 and added to the full load mass of the main inner barrel to obtain the total sand accumulation data. If the auxiliary inner barrel is not provided and only the oversized main inner barrel is used to hold the sand, the main electronic scale must use a high-range, low-precision model, which will result in poor data accuracy and cannot realize high-frequency collection of sand accumulation data.

[0027] (4) The fully automatic sand accumulation meter of the present invention is designed with a combination of a secondary inner barrel, a secondary electronic scale and a main inner barrel, a main electronic scale. Under the premise of ensuring high-precision measurement, the measuring range of the sand accumulation meter is greatly increased. The maximum measuring range of the sand accumulation meter can reach 520kg (i.e., the capacity of the main inner barrel is 200kg, and the usable capacity of the secondary inner barrel 3 is 320kg (20kg / barrel*16 barrels)), which is more than 1000 times that of the currently available all-round automatic sand accumulation meter. In the near-surface environment of super-strong sand transport, the maintenance-free period can be as long as 1 year, while the general all-round automatic sand accumulation meter can only maintain an effective working time of several days.

[0028] (5) The fully automatic sand accumulation meter of the present invention has an electronic scale that is in contact with the inner barrel only, thereby effectively avoiding data drift of the electronic scale; the main electronic scale is in contact with the bottom surface of the main inner barrel only, and is not affected by the conical top cover, the all-round sand accumulation collection assembly, and the influx of wind and sand, thereby reducing the drift value of the main electronic scale to a minimum; the connecting section of the main inner barrel and the auxiliary inner barrel is only welded to the main inner barrel and extends to the center position of the top of the auxiliary inner barrel, and the connecting section of the main inner barrel and the auxiliary inner barrel has no contact with the auxiliary inner barrel, and the auxiliary inner barrel is placed on the auxiliary electronic scale and is in contact with the auxiliary electronic scale only, thereby reducing the drift value of the auxiliary electronic scale to a minimum.

[0029] (6) The fully automatic sand accumulation instrument of the present invention realizes long-term maintenance-free, highly weather-resistant, all-round, and fully automatic observation of sand transport in a strong sand transport environment in the field. When deployed in the field, multiple all-round sand collection components and sand buckets can be used. The data acquisition device, remote transmission system, and power supply system can share one, so that the collection mouth is at different surface heights, and reliable collection, recording, and transmission of all-round sand transport distribution data at different heights can be realized. The data acquisition and recording frequency is 1 Hz, and it is equipped with a 128Msd card, which can continuously store data for more than 2 years, and the data accuracy is 0.01g. It provides a basic, practical, and advanced experimental device for field observations of modern wind and sand physics and geomorphology.

[0030] (7) The starting wind speed of sand particles is an important wind erosion parameter. Currently, the international community can only use the 1 Hz frequency sand number data of the American Sensit wind erosion sensor, with a calculation frequency of 5 minutes, to calculate the starting wind speed. The implementation of the present invention can use the sand mass, i.e., sand transport data, recorded at a frequency of 1 Hz, with a calculation frequency of 5 minutes to calculate the starting wind speed of sand particles. The result can be compared and verified with the starting wind speed value calculated by the wind erosion sensor data, providing a new calculation method for obtaining the starting wind speed of sand particles.
