Description

Technical Field

[0001] This utility model relates to the field of environmental measurement technology, and more specifically, to a sand collection device for wind and sand flow. Background Technology

[0002] Aeolian sand flow is a near-surface sand transport phenomenon formed by airflow carrying loose sand particles from the ground surface, commonly found in arid and semi-arid regions. When wind speed exceeds a critical threshold, sand particles move through three mechanisms: jump, creep, and suspension. Jump accounts for 75%-90% of the total sand transport, manifested as sand particles being bounced into the air by wind force, briefly flying before impacting the ground surface; creep involves sand particles rolling or sliding along the ground surface; and suspension involves fine particles (<0.1 mm) being carried into the high atmosphere by turbulent flow and transported over long distances. Studying the dynamic mechanism of aeolian sand flow is of great significance for preventing and controlling desertification, optimizing the layout of transportation facilities, and understanding the evolution of desert ecosystems.

[0003] Existing technologies typically employ multi-point sand collection devices to collect sand particles from airflow. However, traditional sand collection devices analyze the vertical distribution of sand particles and calculate the amount of sand transported per unit area per unit time by using vertically arranged bag structures. However, the vertically distributed upper bag structure is difficult to collect suspended sand particles by relying solely on natural sand collection. Furthermore, due to the limitations of the bag structure's opening, the airflow will form convection with the sand particles inside the bag to some extent when passing through the device, resulting in low collection efficiency and inconvenience for long-term collection. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing sand collection devices rely on vertically distributed bag structures, which are quite limited and cannot meet the collection needs of suspended sand particles. In view of the problems existing in the prior art, a wind-blown sand collection device is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: it includes a frame and a base, the base is set at the bottom of the frame, and the frame and the base are a plug-in and detachable combination structure;

[0006] The upright frame has several unit boxes arranged vertically. Each unit box contains a sand collecting bag, and a strip groove with a mesh surface is provided through the sand collecting bag on both sides and between the sand collecting bag and the unit box. A side air duct connected to the strip groove is provided at the outer end of the unit box.

[0007] The base is equipped with a suction pump, and the suction pump extends a vertical pump pipe towards the end of the frame, and the vertical pump pipe is connected to the sand collection bag.

[0008] Furthermore: an inner frame that matches the inner frame is provided between the upright frame and the unit box. The inner frame is a strip rail structure, and the unit box slides in conjunction with the inner frame.

[0009] A further preferred embodiment: a pivot is provided at the bottom of the upright frame, and a bearing seat is fixedly provided on the base. The pivot and the bearing seat are assembled by plugging in, and a matching toothed groove is provided between the surface of the pivot and the bearing seat.

[0010] A further preferred embodiment: the upright frame is fitted with an angled protruding combined wing plate at one end relative to the unit box, the front end of the combined wing plate has a slot for connecting with the unit box, and the rear end forms a strip-shaped flange.

[0011] A further preferred embodiment: air ducts are opened on both sides of the connection end between the upright frame and the combined wing plate, and the two ends of the air ducts form an outwardly expanding flow channel structure with the side air duct and the combined wing plate.

[0012] A further preferred embodiment: A pair of leaf plates are hinged to the front sides of the unit box, and a connecting rib is connected between the leaf plates. The connecting rib is sewn and fixed to the open end of the sandbag.

[0013] A further preferred embodiment: a filter screen is embedded in the opening at the connection end of the sandbag unit box.

[0014] The beneficial effects of this utility model are:

[0015] This type of wind-blown sand collection device is based on a vertically arranged sand collection structure. On this basis, the vertically distributed unit-type box structure allows for the establishment of boxes of corresponding specifications according to the specific vertical distribution height and collection environment. Combined with the vertical pump pipe at the end of the unit box and the external pumping structure, airflow can be pumped into the upper unit box to collect suspended sand particles in the airflow in a short time. Furthermore, the internally combined unit box frame and sand collection bag are connected by a side-guided channel structure to avoid airflow convection within the structure, ensuring the stability of sand collection operation over a long period of time.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-4 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0023] A sand collection device for wind and sand flow includes a vertical frame 1 and a base 2. The base 2 is located at the bottom of the vertical frame 1, and the vertical frame 1 and the base 2 are a combination structure for plugging and unplugging.

[0024] Several unit boxes 3 are arranged vertically in the frame 1. Sand collection bags 11 are embedded in the unit boxes 3. A strip groove 13 with a mesh surface is provided through the sand collection bags 11 on both sides and between the sand collection bags 11 and the unit boxes 3. A side air duct 12 connected to the strip groove 13 is provided at the outer end of the unit boxes 3.

[0025] A suction pump is installed in the base 2, and a vertical pump pipe 14 extends from the suction pump of the base 2 toward the end of the upright frame 1, and the vertical pump pipe 14 is connected to the sand collection bag 11.

[0026] The sand collection device consists of a frame structure with a vertical frame 1 as the longitudinal axis, on which multiple unit boxes 3 are installed. The unit boxes 3 are arranged vertically, and their depth is determined by the height of the frame 1 and the vertical height of the sand collection. The unit box 3 uses the front window as the airflow inlet. After the airflow enters, the sand particles it carries will enter the sand collection bag 11. The airflow and sand particles are separated by the mesh surface of the strip groove 13 on the side of the unit box 3, so that the sand particles are intercepted and flowed into the sand collection bag 11. The remaining airflow is discharged along the strip groove 13 and the side air duct 12, so as to avoid the formation of a convection environment in the unit box 3 when collecting sand particles, which would affect the normal collection of sand particles.

[0027] Meanwhile, considering the poor collection effect of natural collection on suspended sand particles in the upper airflow, an external suction pump can be connected to the base 2. After the lower layer of creeping and jumping sand particles are collected, the suction pump can be directed to act on the upper unit box 3 along the vertical pump pipe 14 according to the specified unit time data and airflow data. The suction airflow is used to collect suspended sand particles in the airflow, thus completing the sand collection work of the wind-blown sand flow.

[0028] Among them, an inner frame 6 with internal and external matching is set between the upright frame 1 and the unit box 3. The inner frame 6 is a strip rail structure. The unit box 3 and the inner frame 6 slide together. The inner frame 6 structure further restricts the insertion and combination structure of the upright frame 1 and the unit box 3. The strip rail improves the combination accuracy of the unit box 3, the inner frame 6, and the upright frame 1. At the same time, it is convenient to classify and collect sand particles at the corresponding height by separating the designated unit box 3 after the sand collection work is completed.

[0029] The bottom of the frame 1 is provided with a rotating shaft 8, and the base 2 is fixedly provided with a bearing seat 4. The rotating shaft 8 and the bearing seat 4 are assembled by plugging in, and the surface of the rotating shaft 8 and the bearing seat 4 are provided with matching tooth grooves. Considering the influence of wind direction changes on the sand collection effect of wind and sand flow, the device can adjust the sand collection direction of the entire vertically distributed unit box 3 by rotating the frame 1 along the bearing seat 4 while setting the sand collection direction of the frame 1 and the unit box 3 through the base 2.

[0030] Furthermore, an angled, protruding combined wing plate 5 is embedded at one end of the upright frame 1 relative to the unit box 3. The front end of the combined wing plate 5 has a slot for connecting with the unit box, and the rear end forms a strip-shaped flange. Air ducts 7 are opened on both sides of the connection end between the upright frame 1 and the combined wing plate 5, and the two ends of the air ducts 7 form an outwardly expanding flow channel structure with the side air duct 12 and the combined wing plate 5. Figure 2 As shown, based on the above, the frame 1 structure can be set with the corresponding sand collection angle according to the needs of the sand collection site. It can be combined with the combined wing plate 5 at one end of the frame 1 as the guiding structure of the airflow channel. After the airflow enters the unit box 3 through the frame 1, it acts on the surface of the combined wing plate 5 along the side air duct 12 and the air groove 7. The angle of the combined wing plate 5 is guided by the contact between the airflow on both sides and the combined wing plate 5. Thus, the combined wing plate 5 can be calibrated along the shaft seat 4 to the positive direction of the airflow under the influence of the airflow direction, so as to ensure the sand collection effect of the device.

[0031] Furthermore, a pair of leaf plates 9 are hinged to the front sides of the unit box 3, and a connecting rib 10 is connected between the leaf plates 9. The connecting rib 10 is sewn and fixed to the open end of the sand collection bag 11. The unit box 3 can open and close the sand collection window of the unit box 3 according to the movable leaf plates 9 at the front end, so as to close the sand collection end at the corresponding height. The connecting rib 10 connected between the leaf plates 9 serves as a linkage structure between the left and right leaf plates 9. The opening and closing angle of the two leaf plates 9 is maintained according to the curvature of the connecting rib 10. At the same time, the combination of the sand collection bag 11 and the connecting rib 10 is combined with the opening and closing changes of the leaf plates 9 to change the curvature shape of the connecting rib 10, so as to achieve the effect of opening and closing the window of the sand collection bag 11 at the same time, ensuring the sealing of the opening and closing structure of the unit box 3.

[0032] Furthermore, a filter screen is embedded at the connection end opening of the sand collection bag 11 unit box 3. The filter screen at the window is relatively larger than the mesh structure of the sand collection bag 11 and the strip groove 13, so as to avoid large-area impurities in the airflow from entering the sand collection bag 11 and affecting the normal sand collection work when collecting sand particles in the wind and sand flow.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
