Description

Technical Field

[0001] This utility model relates to the field of sand collection instruments, and more specifically, to an omnidirectional gradient sand collection instrument. Background Technology

[0002] To effectively prevent and control sandstorm disasters, it is essential to first understand the fundamental laws governing sand movement. Sand particle movement in sandstorms includes two forms: spiral movement, precipitation, and suspension. Based on these different forms of movement, sandstorms can be divided from top to bottom into suspension layers, precipitation layers, and creep layers. As a part of sandstorms, the study of sediment transport in the creep layer is an important topic. According to existing literature, methods for studying sediment transport in the creep layer include directly measuring the sediment transport using a trapping instrument; and estimating the sediment transport in the creep layer by using the distribution curve of sediment transport along the height of the sandstorm down to the ground surface.

[0003] However, the creep layer sediment transport data obtained by the two methods mentioned above include both the creep layer sediment transport and the influence of some transition layer sand particles. The inability to eliminate the influence of transition layer sand particles will lead to research results that do not reflect the objective situation. Therefore, accurately measuring the creep layer sediment transport has become a focus of attention in the field of aeolian science. Many instruments are available for measuring creep layer sediment transport. Among them are truly omnidirectional sediment collectors that utilize bearings and a wind deflector system, but existing omnidirectional sediment collectors still have certain shortcomings. During use, the mesh used to trap sand and expel air is easily clogged, failing to create an internal and external pressure difference or resulting in a small pressure difference, thus failing to effectively trap sand and dust, leading to a significant difference between the actual and actual sediment transport amounts. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an omnidirectional gradient sand collection device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an omnidirectional gradient sand collector, including a bracket, a rotating bushing, a sand collector, and a guide. The sand collector and the guide are mounted on the bracket via the rotating bushing. The rotating bushing includes a fixed sleeve fitted on the bracket, a rotating sleeve fitted on the fixed sleeve, a connecting plate that engages with the sand collector, and a slot that engages with the guide.

[0007] The sand collector includes a box body, one end of which is fitted with a connecting groove that engages with a connecting plate. A box cover, communicating with the box body, is fixed to the top of the box body. A sand collection port is opened at the tip of the box cover. A ventilation window is opened on the box cover, and a mesh screen is installed inside the ventilation window. A vibrating plate is hinged to the box cover, one end of which extends above the ventilation window and contacts the mesh screen. A spring is installed on the box cover, the top of which contacts the other end of the vibrating plate. A rotating shaft is rotatably mounted on the box body, and wind-driven fan blades are installed at both ends of the rotating shaft. An inclined turntable that cooperates with the vibrating plate is fixed on the rotating shaft.

[0008] As a preferred technical solution of this utility model, fastening bolts are passed through the outer circular surfaces of the top and bottom of the fixed sleeve. One end of the fastening bolt located inside the fixed sleeve contacts the bracket. Support bearings are fitted on the fixed sleeve at the top and bottom positions of the rotating sleeve.

[0009] As a preferred technical solution of this utility model, the bottom end of the box cover is fixed with a sand and dust collection slot extending into the box body, an electronic scale is installed at the bottom of the box body, and a sand collection box is installed on the top of the electronic scale.

[0010] As a preferred embodiment of the present invention, the guide includes a thin plate arranged in a triangular shape, a support plate that mates with a slot is installed at the tip of the thin plate, and an expansion rod is installed inside the thin plate.

[0011] As a preferred embodiment of this utility model, the bracket includes a support column that cooperates with the fixing sleeve, a mounting base plate is fixed at the bottom end of the support column, and a cross rod is fixed at the top end of the support column.

[0012] The advantages of this utility model are:

[0013] 1. This utility model uses wind power to drive the rotating shaft to rotate, which in turn drives the vibrating plate through the tilting turntable. The vibrating plate drives the screen to vibrate through its own vibration, which can shake off the sand and dust clogging the screen, avoid the screen from being blocked, keep the screen transparent, thereby maintaining the pressure difference between the sand collector and the outside world, maintaining the collection effect of external sand and dust, and improving the accuracy of sand and dust collection.

[0014] 2. This utility model connects the sand collector, guide and rotating bushing through connecting plate and slot, so that the various parts of the omnidirectional gradient sand collector can be separated, which is convenient for installation, maintenance and replacement.

[0015] 3. This utility model allows for the adjustment of the sand collection cylinder height at any time during field observations of wind and sand flow; the sand collection units at different heights will automatically and flexibly rotate with the wind direction throughout the year, ensuring that the sand inlet is accurately aligned with the direction of the incoming wind; all sand particles entering the sand inlet pipe settle in the sand collection box, resulting in high testing accuracy.

[0033] Example 1:

[0034] Please see Figure 1-9 Structural diagram; the present invention provides the following technical solution:

[0035] Specifically, it refers to an omnidirectional gradient sand collector, including a support 1, a rotating bushing 2, a sand collector 3, and a guide 4. The sand collector 3 and the guide 4 are mounted on the support 1 via the rotating bushing 2. The support 1 includes a support column 101 that cooperates with a fixed sleeve 201. A mounting base plate 102 is fixed to the bottom end of the support column 101, and a cross rod 103 is fixed to the top end of the support column 101. The guide 4 includes a thin plate 401 arranged in a triangular shape. A support plate 402 that cooperates with a slot 204 is installed at the tip of the thin plate 401, and an expansion rod 403 is installed inside the thin plate 401.

[0036] The sand collector 3 includes a box body 301. One end of the box body 301 has a connecting groove 302 that engages with a connecting plate 203. A box cover 303, communicating with the box body 301, is fixed to the top of the box body 301. A sand collection port 304 is formed at the tip of the box cover 303. A ventilation window is formed on the box cover 303, and a mesh screen 305 is installed inside the ventilation window. A vibrating plate 306 is hinged to the box cover 303, with one end extending above the ventilation window and contacting the mesh screen 305. A spring 307 is installed on the top of the box 301, with its top end in contact with the other end of the vibrating plate 306. A rotating shaft 308 is rotatably installed on the box 301. Wind-driven fan blades 309 are installed at both ends of the rotating shaft 308. An inclined turntable 310 that cooperates with the vibrating plate 306 is fixed on the rotating shaft 308. A sand collection slot 311 extending into the box 301 is fixed at the bottom of the box cover 303. An electronic scale 312 is installed at the bottom of the box 301. A sand collection box 313 is installed on the top of the electronic scale 312.

[0037] The sand collector 3 features a streamlined design for both the housing 301 and the cover 303, allowing sand and dust to enter with minimal interference. The mesh 305 above the cover 303 provides good permeability, reducing obstruction to the sand and dust flow. The sand collector 3 is mounted on the support 1 via a rotating bushing 2. The rotating bushing 2 contains a support bearing 206, allowing for flexible rotation. A guide 4 above ensures the sand collector 3 rotates freely with the prevailing wind direction, ensuring the sand collection port 304 on the housing 301 always faces the eroding wind direction. Under the influence of the wind field around the sand collector, the sand and dust flow enters the cover 303 through the collection port 304. The streamlined shape of the cover 303 creates a Venturi effect, reducing the sand and dust velocity. The sand and dust entering the cover 303 are deposited in the sand collection box 313 by gravity, while air is exhausted through the ventilation screen formed by the mesh 305 inside the ventilation window due to the pressure difference between the inside and outside. The sand collector 3 has a simple structure, is inexpensive, and easy to use. The sand inlet can always be pointed in the direction of erosion.

[0038] Example 2:

[0039] Based on Specific Embodiment 1, the difference in this embodiment is as follows:

[0040] like Figure 1 , 6As shown in Figures 7 and 8, the rotating sleeve 2 includes a fixed sleeve 201 fitted onto the support 1, a rotating sleeve 202 fitted onto the fixed sleeve 201, a connecting plate 203 fixed on the outer surface of the rotating sleeve 202 to engage with the sand collector 3, and a slot 204 to engage with the guide 4; fastening bolts 205 penetrate the top and bottom outer surfaces of the fixed sleeve 201, with one end of the fastening bolt 205 inside the fixed sleeve 201 contacting the support 1; support bearings 206 are fitted onto the fixed sleeve 201 at the top and bottom positions of the rotating sleeve 202. Under the action of the two support bearings 206, the rotating sleeve 202 can rotate with very little force. Combined with the sand collector 3 and the guide 4, this allows the sand collector 3 to face the sandstorm directly. Furthermore, by adjusting the fastening bolts 205, the rotating sleeve 2 can be positioned at different heights on the support column 101, enabling the collection of sand samples from different heights at the same location. This eliminates the need for constant monitoring and maintenance by staff, allowing for long-term observation in the field.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
