Description

Technical Field

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

[0002] At present, sand retaining walls are usually set up in areas ravaged by wind and sand, because wind and sand are mainly formed by wind and sand flow carried by air flow. Sand retaining walls can directly block the advance of sand particles. When the wind and sand flow encounters the sand retaining wall, the sand particles will hit the surface of the wall due to their own inertia, and then accumulate at the bottom or near the wall under the action of gravity, thereby intercepting the sand and dust.

[0003] Most of the existing sand retaining walls are rigid fixed structures, such as masonry walls, metal plates or concrete slabs spliced ​​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 facing 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: A spring-type sand retaining wall comprises two columns, a plurality of wind shields are arranged between the two columns from top to bottom, and each wind shield is provided with an air outlet; a fixing assembly is arranged on the bottom wall of the two columns, and the fixing assembly is used to connect the two columns to the ground; two spring grooves are extended inwardly from the upper surface of the fixing assembly, and the two columns are respectively inserted into the two spring grooves; an elastic member is arranged in each spring groove, and the two ends of the elastic member are respectively fixedly connected to the bottom wall of the spring groove and the column.

[0007] By adopting the above scheme, the fixing assembly can connect the column 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 elasticity, 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.

[0008] Furthermore, each windshield is arranged in an arc shape, with the two ends of the central protrusion respectively connected to two columns, and the middle part protrudes toward the end close to the windward side; the windshield located in the middle of the plurality of windshields has the largest protrusion, and the protrusion gradually decreases toward the upper and lower sides.

[0009] By adopting the above solution, the wall is overall curved, and the curved windbreak wall can make the wind and sand flow along the wall surface, changing the original straight-line 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.

[0010] Furthermore, there are gaps between adjacent windshields.

[0011] By adopting the above solution, 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.

[0012] 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.

[0013] 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, thereby preventing the elastic member from deforming in the horizontal direction.

[0014] Furthermore, the side wall of the limiting groove is recessed inwardly to form a sliding groove, and a sliding block is fixedly connected to the side wall of the limiting rod corresponding to the sliding groove. The sliding block is plug-fitted with the sliding groove, and the sliding block can move up and down along the sliding groove.

[0015] Furthermore, a threaded hole is provided on the top wall of the slide groove, 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 groove.

[0016] By adopting the above scheme, 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 deformation degree of the elastic member.

[0017] 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 threadedly wound 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.

[0018] Furthermore, a connecting plate is fixedly connected to the bottom wall of the threaded rod, and a plurality of connecting thorns are evenly arranged on the circumference of the connecting plate, and each connecting thorn is arranged parallel to the horizontal plane of the bottom plate.

[0019] 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 between the plug-in rod and the ground is more stable.

[0020] Furthermore, the inner wall of the air outlet is provided with some interference flow sheets.

[0021] By adopting the above scheme, when the wind and sand airflow passes through the side wall of the air outlet, the interference flow sheet will cause 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; thereby increasing the interception efficiency of sand and dust particles and strengthening the filtering ability of the air outlet to prevent wind and sand.

[0022] Furthermore, a guide groove is formed in a recessed box inside the inner wall of the air outlet, and the guide groove is arc-shaped and arranged along the flow direction of the airflow.

[0023] By adopting the above scheme, the flow groove 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 groove and flow 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.

[0024] In summary, this application has the following technical effects: 1. By setting up the elastic part, 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 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 prolonging the service life of the sand-proof wall when the wind and sand continue to impact; 2. By setting up the curved wind shield, the wind and sand flow can flow along the wall surface, changing the original straight-line movement path of the wind and sand, and the wind and sand flow can 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 can be dispersed; 3. By providing a limit rod, the limit rod slides along the limit groove, so that the elastic member can only deform in the vertical direction, avoiding the elastic member from deforming in the horizontal direction.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1: Reference Figure 1-Figure 3 The 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 two columns 1 are provided, 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 respectively fixedly connected to the two columns 1 and each wind shield 2 is provided with a plurality of air outlet holes 21; the upper surface of the fixing assembly 3 extends inwardly to provide two elastic grooves 311, and the two columns 1 are respectively inserted into the two elastic grooves 311; two elastic members 4 are provided, so that an elastic member 4 is correspondingly provided 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 setting 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 the embodiment, the air outlet holes 21 are rhombus-shaped.

[0029] Reference Figure 1 Each wind shield 2 is arranged in an arc shape, and each wind shield 2 is arranged in a state where the middle part bulges toward one end close to the windward side, and the two ends are respectively fixedly connected to the two columns 1; and the wind shield 2 located in the middle of the plurality of wind shields 2 has the largest bulge, 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 arc-shaped 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.

[0030] Reference Figure 1 There is a gap between adjacent wind shield plates 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.

[0031] 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.

[0032] Reference Figure 3 The side wall of each limiting groove 3111 is recessed inward to form a slide groove 31111, and the side wall of the limiting rod 11 is fixedly connected with a slider 111 corresponding to the slide groove 31111. The slider 111 is plugged into and matched with the slide groove 31111, and the slider 111 can move up and down along the slide groove 31111; when the limiting rod 11 reciprocates along the limiting groove 31111, it can drive the slider 111 to move up and down along the slide groove 31111, so that the width of the slide groove 31111 in the up and down 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 arranged 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.

[0033] 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 bottom plate 31, a plug rod 32, a connecting plate 33 and a connecting thorn 34, the upper surface of the bottom plate 31 is used to connect with the column 1, that is, the elastic groove 311 is formed by the upper surface of the bottom plate 31 inwardly opening; the plug rod 32 is arranged on the lower surface of the bottom plate 31, the plug rod 32 is fixedly connected to the bottom plate 31, and the plug rod 32 is inserted into the ground; a reinforcing plate 321 is arranged on the outer side 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 reinforcing 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 thorns 34 are set, and the plurality of connecting thorns 34 are radially and evenly fixedly connected to the circumference of the connecting plate 33, and each connecting thorn 34 is set horizontally with the horizontal plane of the bottom plate 31; the setting of the connecting thorns 34 is used to increase the horizontal resistance between the plug-in rod 32 and the ground, making the plug-in state of the plug-in rod 32 and the ground more stable.

[0034] Embodiment 2: 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 recessed 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 at 1-2 mm, which can ensure an effective guiding effect on the airflow without excessively weakening the structural strength of the air outlet 21; the width is designed to be 3-5 mm, which helps the airflow to smoothly enter the guide groove 211 and maintain a stable flow state.

[0035] Reference Figure 4 When the airflow rushes into the air outlet 21 at a high speed, the guide groove 211 changes the direction of the airflow by virtue of its own arc shape, so that the airflow 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 airflow guidance, thereby preventing the sand and dust particles from accumulating in the middle of the air outlet 21, thereby achieving the effect of evacuating the sand and dust from the air outlet 21.

[0036] Embodiment three: Reference Figure 5 The difference between this embodiment and the second embodiment is that the inner wall of the air outlet 21 is provided with a spoiler 212, and the spoiler 212 is fixedly connected to the inner wall of the air outlet 21 in a fish scale shape as a whole; in this embodiment, the protrusion height of the spoiler 212 is controlled at 0.1-0.3mm, and the setting of the spoiler 212 disturbs the flow state of the airflow near the air outlet 21. When the wind and sand airflow passes along the side wall of the air outlet 21, the spoiler 212 causes the airflow to generate local turbulence and vortex flow; under the action of these vortices, the 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 interception efficiency of the sand and dust particles is increased, and the effect of strengthening the filtering ability of the air outlet 21 for sand and dust is achieved.

[0037] The implementation principle of an elastic sand retaining wall in the first embodiment of the present application is as follows: insert the plug-in rod 32 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 plate 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.

[0038] 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 modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
