Description

Technical Field

[0001] The present application relates to the technical field of windbreak and sand fixation engineering, and in particular to a resilient sand retaining wall. Background Art

[0002] Sand retaining walls are commonly installed in areas prone to sandstorms. Sand is primarily a flow of sand carried by air currents. Sand retaining walls directly block the flow of sand. When the sand encounters the retaining wall, the inertia of the sand particles causes them to collide with the wall's surface. Gravity then forces them to accumulate at or near the wall's base, trapping the dust.

[0003] Most existing sand retaining walls are rigid fixed structures, such as masonry walls, metal plate or concrete plate splicing walls, etc.

[0004] The above-mentioned existing technical solutions have the following defects: although this type of sand retaining wall can block wind and sand to a certain extent, when faced with continuous strong wind and sand impact, the wind and sand frequently hit the same position, causing serious wear on the wall surface, which will reduce the service life of the sand retaining wall. Summary of the Invention

[0005] In order to achieve the effect of increasing the service life of the sand-proof wall when the wind and sand continue to impact, the present application provides a resilient sand-proof wall.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A spring-type sand retaining wall includes two columns, with several wind shields arranged between the two columns from top to bottom, and each wind shield is provided with an air outlet; the bottom walls of the two columns are provided with a fixing assembly, and the fixing assembly is used to connect the two columns to the ground; the upper surface of the fixing assembly extends inward to form two spring grooves, and the two columns are respectively inserted into the two spring grooves; each spring groove is provided with an elastic part, and the two ends of the elastic part are respectively fixedly connected to the bottom wall of the spring groove and the column.

[0008] By adopting the above solution, the fixing assembly can connect the columns to the ground, so that the entire wall is connected to the ground; and because the elastic member is provided, when the wind and sand flow blows towards the wall, the two columns can move up and down under the action of the elastic member, which can drive the wind shield to move accordingly. The up and down movement of the wind shield can achieve the effect of disturbing the wind and sand flow, thereby achieving the effect of increasing the service life of the sand-proof wall when the wind and sand continue to impact.

[0009] Furthermore, each windshield is arranged in an arc shape, with the two ends of the central protrusion respectively connected to the two pillars, and the middle part protrudes toward the end close to the windward side; the windshield located in the middle among the several windshields has the largest protrusion, and the protrusion gradually decreases toward the upper and lower sides.

[0010] By adopting the above solution, the wall is curved as a whole. The curved windbreak wall can make the wind and sand flow along the wall surface, changing the original linear movement path of the wind and sand, and can disperse the wind and sand flow in front of the wall into two or more smaller airflows, so that the concentrated impact force of the wind and sand on the wall is dispersed.

[0011] Furthermore, gaps are left between adjacent windshields.

[0012] By adopting the above solution, the setting of the gap can reduce the resistance of the wind and sand flow to the entire wall, thereby increasing the service life of the wall.

[0013] Furthermore, the bottom wall of each of the elastic grooves is provided with a limit groove downwardly along the length direction; a limit rod is passed through the inside of the elastic member, one end of the limit rod is fixedly connected to the bottom wall of the column, and the other end is inserted into the limit groove; during the deformation of the elastic member, the limit rod slides back and forth along the limit groove.

[0014] By adopting the above solution, the limiting rod slides along the limiting groove, so that the elastic member can only deform in the vertical direction, and the elastic member is prevented from deforming in the horizontal direction.

[0015] Furthermore, the side wall of the limiting groove is recessed inward to form a sliding groove, and the side wall of the limiting rod is fixedly connected to the sliding groove corresponding to the sliding groove. The sliding block is plugged into the sliding groove and can move up and down along the sliding groove.

[0016] Furthermore, a threaded hole is provided on the top wall of the slide, a travel control rod is provided in the threaded hole, the travel control rod is threadedly connected to the threaded hole, and the travel control rod can control the maximum distance that the slider slides up and down in the slide.

[0017] By adopting the above solution, the slide groove provides a sliding area for the slider, and because a stroke control rod is provided, the depth of the stroke control rod inserted into the slide groove can be controlled by controlling the relative position of the stroke control rod and the threaded hole. In this way, the range of the slider sliding up and down in the slide groove can be controlled; controlling the sliding range of the slider can control the degree of deformation of the elastic member.

[0018] Furthermore, the fixing assembly includes a base plate and a plug-in rod, and the two columns are connected to the upper surface of the base plate; the plug-in rod is fixedly connected to the lower surface of the base plate, and the plug-in rod is inserted into the ground; a circle of reinforcing plates is provided on the surrounding side of the plug-in rod, and the reinforcing plates are threaded around the surrounding side of the plug-in rod, and the reinforcing plates are used to increase the friction after the plug-in rod is plugged into the ground.

[0019] Furthermore, a connecting plate is provided at one end of the plug-in rod away from the bottom plate, and a plurality of connecting thorns are evenly provided on the circumference of the connecting plate, and each connecting thorn is arranged parallel to the horizontal plane of the bottom plate.

[0020] By adopting the above solution, the setting of the connecting thorns is used to increase the resistance between the plug-in rod and the ground in the horizontal direction, so that the plug-in state of the plug-in rod and the ground is more stable.

[0021] Furthermore, an interference sheet is provided on the inner wall of the air outlet.

[0022] By adopting the above scheme, when the wind and sand airflow passes through the side wall of the air outlet, if the interference flow sheet causes the airflow to produce local turbulence and vortex flow; under the action of these vortices, the sand and dust particles are drawn into them, constantly changing their movement trajectory, and moving closer to the side wall of the air outlet under the combined action of centrifugal force and airflow; the interception efficiency of sand and dust particles is increased, and the filtering ability of the air outlet to prevent wind and sand is enhanced.

[0023] Furthermore, the inner wall of the air outlet is recessed inward to form a guide groove, which is arc-shaped and arranged along the direction of air flow.

[0024] By adopting the above solution, the flow channel changes the direction of the airflow with the help of its own arc shape, so that the airflow flows along the side wall of the air outlet; in this way, the sand and dust particles are "pushed" along the side wall of the guide channel and out to the outlet under the dual effects of inertia and airflow guidance, avoiding the accumulation of sand and dust particles in the middle of the air outlet, thereby achieving the effect of evacuating sand and dust from the air outlet.

[0025] In summary, this application has the following technical effects:

[0026] By setting up elastic parts, when the wind and sand flow blows towards the wall, the two columns can move up and down under the action of the elastic, which can drive the wind deflector to move accordingly. The up and down movement of the wind deflector can achieve the effect of disturbing the wind and sand flow, thereby achieving the effect of extending the service life of the sand-proof wall when the wind and sand continue to impact;

[0027] By setting up the curved wind shield, the wind and sand flow can be made to flow along the wall surface, changing the original straight-line movement path of the wind and sand. The wind and sand flow can also be dispersed into two or more smaller airflows in front of the wall, so that the concentrated impact force of the wind and sand on the wall is dispersed.

[0028] By providing a limiting rod, the limiting rod slides along the limiting groove, so that the elastic member can only deform in the vertical direction, and the elastic member is prevented from deforming in the horizontal direction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present application is further described in detail below with reference to the accompanying drawings. Example

[0036] Reference Figure 1-Figure 3 The present embodiment provides an elastic sand retaining wall, comprising a column 1, a wind shield 2, an elastic member 4 and a fixing assembly 3, wherein the column 1 is provided with two, and a plurality of wind shields 2 are provided, and the plurality of wind shields 2 are arranged along the height direction of the two columns 1; both ends of each wind shield 2 are fixedly connected to the two columns 1 respectively, and a plurality of air outlet holes 21 are opened on each wind shield 2; the upper surface of the fixing assembly 3 extends inwardly to form two elastic grooves 311, and the two columns 1 are respectively inserted into the two elastic grooves 311; there are two elastic members 4, so that an elastic member 4 is correspondingly arranged in each elastic groove 311, and the two ends of each elastic member 4 are respectively fixedly connected to the bottom wall of the elastic groove 311 and the column 1; the arrangement of the elastic member 4 enables the two columns 1 to move up and down along the elastic groove 311 under the action of the wind and sand flow, thereby achieving the effect of disturbing the wind and sand flow; in this embodiment, the air outlet holes 21 are diamond-shaped.

[0037] Reference Figure 1 Each windshield 2 is arranged in an arc shape, and each windshield 2 is arranged in a state where the middle part bulges toward the end close to the windward side, and the two ends are fixedly connected to the two columns 1 respectively; and the windshield 2 located in the middle of the several windshields 2 is the most bulging, and the bulge gradually decreases toward the upper and lower ends. This arrangement makes the entire wall side wall arc-shaped; specifically, according to Bernoulli's principle, speed changes lead to pressure changes. On the convex surface of the curved wall, the air flow speed is fast and the pressure is relatively low; on the concave surface, the air flow speed is slow and the pressure is relatively high; the existence of this pressure difference will generate a force perpendicular to the direction of the air flow, causing the air flow to produce a vertical motion component, thereby disrupting the original relatively stable flow state of the air flow, and thereby reducing the impact of the air flow on the same position.

[0038] Reference Figure 1 There is a gap between adjacent windshields 2. The setting of the gap can reduce the resistance of the wind and sand flow to the entire wall and increase the service life of the wall.

[0039] Reference Figure 3 The bottom wall of each elastic groove 311 is provided with a limiting groove 3111 downwardly along the length direction; a limiting rod 11 is passed through the elastic member 4, one end of the limiting rod 11 is fixedly connected to the bottom wall of the column 1, and the other end is inserted into the limiting groove 3111, so that during the deformation of the elastic member 4, the limiting rod 11 slides back and forth along the limiting groove 3111; the limiting rod 11 moves along the limiting groove 3111 to limit the deformation direction of the elastic member 4.

[0040] Reference Figure 3 The side wall of each limiting groove 3111 is recessed inward to form a sliding groove 31111. The side wall of the limiting rod 11 is fixedly connected to the sliding groove 31111 corresponding to the sliding groove 31111. The sliding groove 111 is plugged into and matched with the sliding groove 31111. The sliding groove 111 can move up and down along the sliding groove 31111. When the limiting rod 11 reciprocates along the limiting groove 3111, it can drive the sliding groove 111 to move up and down along the sliding groove 31111. In this way, the width of the sliding groove 31111 in the vertical direction can limit the deformation of the elastic member 4. A threaded hole is provided on the top wall of the slide groove 31111, and a stroke control rod 5 is provided in the threaded hole, and the stroke control rod 5 is threadedly connected to the threaded hole; by rotating the stroke control rod 5 around the threaded hole, the depth of the stroke control rod 5 inserted into the slide groove 31111 can be controlled, so that the range of the slider 111 sliding up and down in the slide groove 31111 can be controlled; controlling the sliding range of the slider 111 can control the deformation degree of the elastic member 4; the relationship between the stroke control rod 5 and the threaded hole can be adjusted according to the on-site conditions.

[0041] Reference Figure 1-Figure 2, there are two fixing components 3, so that each column 1 corresponds to a fixing component 3, each fixing component 3 includes a base plate 31, a plug rod 32, a connecting plate 33 and a connecting thorn 34, the upper surface of the base plate 31 is used to connect with the column 1, that is, the elastic groove 311 is formed by the upper surface of the base plate 31 inwardly; the plug rod 32 is provided on the lower surface of the base plate 31, the plug rod 32 is fixedly connected to the base plate 31, and the plug rod 32 is inserted into the ground; a reinforcing plate 321 is provided on the outside of the plug rod 32, and the reinforcing plate 321 is threadedly wound around the outer wall of the plug rod 32 and fixed to the plug rod 32 The setting of the connection and reinforcement plate 321 increases the friction between the plug-in rod 32 and the ground, making the plug-in of the plug-in rod 32 and the ground more stable; the connecting plate 33 is set at the end of the plug-in rod 32 away from the bottom plate 31, and the connecting plate 33 is fixedly connected to the plug-in rod 32, and a plurality of connecting spikes 34 are set, and the plurality of connecting spikes 34 are radially and evenly fixedly connected to the circumference of the connecting plate 33, and each connecting spike 34 is set horizontally with the horizontal plane of the bottom plate 31; the setting of the connecting spikes 34 is used to increase the horizontal resistance of the plug-in rod 32 and the ground, so that the plug-in state of the plug-in rod 32 and the ground is more stable. Example

[0042] Reference Figure 4 The difference between this embodiment and the first embodiment is that each air outlet 21 is circular, and the inner wall of each air outlet 21 is evenly provided with an inwardly concave guide groove 211. Each guide groove 211 is arranged along the flow direction of the wind and sand flow, and each guide groove 211 is arc-shaped; in this embodiment, the depth of the guide groove 211 is controlled to be 1-2 mm. This depth can ensure effective guidance of the airflow without excessively weakening the structural strength of the air outlet 21; the width is designed to be 3-5 mm. Such a width helps the airflow to smoothly enter the guide groove 211 and maintain a stable flow state.

[0043] Reference Figure 4 When the air flows into the air outlet 21 at high speed, the guide groove 211 changes the direction of the air flow by virtue of its own arc shape, so that the air flow flows along the side wall of the air outlet 21; in this way, the sand and dust particles are "pushed" along the side wall of the guide groove 211 and flow out to the outlet under the dual effects of inertia and air flow guidance, preventing the sand and dust particles from accumulating in the middle of the air outlet 21, thereby achieving the effect of evacuating sand and dust from the air outlet 21. Example

[0044] Reference Figure 5The difference between this embodiment and the second embodiment is that the inner wall of the air outlet 21 is provided with a flow-interference piece 212, and the spoiler 212 is fixedly connected to the inner wall of the air outlet 21 in a fish-scale shape. In this embodiment, the protrusion height of the spoiler 212 is controlled at 0.1-0.3 mm. The setting of the spoiler 212 disrupts the flow state of the airflow near the air outlet 21. When the wind and sand airflow passes through the side wall of the air outlet 21, the flow-interference piece 212 causes the airflow to generate local turbulence and vortex flow. Under the action of these vortices, sand and dust particles are drawn into them, constantly changing their motion trajectory, and moving closer to the side wall of the air outlet 21 under the combined action of centrifugal force and airflow. The effect of increasing the interception efficiency of sand and dust particles and strengthening the filtering ability of the air outlet 21 for sand and dust is achieved.

[0045] The implementation principle of an elastic sand retaining wall in the first embodiment of the present application is as follows: the plug-in rod 32 is inserted into the ground so that the wall is connected to the ground; then when the wind blows towards the wall, the elastic member 4 drives the column 1 to move up and down in the elastic groove 311 under its own elastic action; the column 1 drives the wind shield 2 to move up and down, so that the position of the air outlet 21 is displaced up and down, thereby achieving the effect of disturbing the wind and sand flow and preventing the wind and sand flow from continuously hitting the same position.

[0046] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
