Description

Technical Field

[0001] This application relates to the field of engineering sand control, and in particular to a double-layer wheeled sand retaining wall. Background Technology

[0002] With the rapid economic development in western my country, urban infrastructure construction, including railways and highways, is being carried out extensively in the deserts and Gobi regions of Northwest my country. These areas are characterized by sparse vegetation and frequent sandstorms. Since the opening of the Lanzhou-Xinjiang Railway and the Qinghai-Tibet Railway, sandstorms have become a significant threat to the safe operation of trains. Train stoppages caused by sandstorms burying railways have resulted in enormous economic losses for travelers and railway transportation.

[0003] Existing engineering sand control measures mainly include sand stabilization and sand blocking, with sand blocking measures being more widely used. Commonly used sand blocking measures include concrete sleeper sand retaining walls, PE mesh high vertical sand barriers, and reed sand retaining fences. These engineering sand control measures have played a certain role in the prevention and control of wind and sand disasters in existing railways, highways, and other projects.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing sand-blocking measures all rely on their own performance to forcibly block wind and sand, which makes the sand-blocking measures easy to be damaged and shortens their service life. Summary of the Invention

A cleaning device is installed between adjacent connecting plates to clean the sand deposited between the windward and leeward sides.

[0009] Furthermore, the cleaning device includes a driving component, a reciprocating screw, a slider, and a sand-cleaning component. The driving component is fixedly connected to the connecting plate. Both ends of the reciprocating screw are rotatably connected to the connecting plate. The driving component is connected to the reciprocating screw to drive the reciprocating screw to rotate. The slider is disposed between the two connecting plates. The slider is threadedly connected to the reciprocating screw. The slider is fixedly connected to the sand-cleaning component. The rotation of the reciprocating screw is used to drive the slider and the sand-cleaning component to slide between the two connecting plates.

[0010] Furthermore, the slider is also provided with a guide rod, the two ends of which are fixedly connected to two connecting plates respectively, and the guide rod is slidably connected to the slider.

[0011] Furthermore, the drive unit is equipped with a power supply device, which includes a micro generator and a storage battery. Each shaft is equipped with a micro generator, the rotor of the micro generator is fixedly connected to the shaft, the micro generator is fixedly connected to the crossbar, the storage battery is fixedly connected to the column, each micro generator is electrically connected to the storage battery, and the storage battery is electrically connected to the drive unit.

[0012] Furthermore, a rectifier is provided between the micro generator and the battery. The rectifier is electrically connected to both the micro generator and the battery. The rectifier is used to convert the variable DC power generated by wind power generation into stable DC power.

[0013] Furthermore, a connecting device is provided between the micro generator and the crossbar. The connecting device includes a bearing plate and a support rod. The bearing plate is fixedly connected to the crossbar and the micro generator. The two ends of the support rod are respectively fixed to the crossbar and the end of the bearing plate away from the crossbar.

[0014] Furthermore, the limiter is disposed at the end of the rotating shaft that passes through the crossbar and is away from the impeller. The limiter includes a fixed ratchet, a sliding ratchet, and an elastic element. The fixed ratchet is fixedly connected to the end of the rotating shaft away from the impeller. The sliding ratchet is disposed between the fixed ratchet and the crossbar and is sleeved on the outside of the rotating shaft. The sliding ratchet is slidably connected to the rotating shaft. The elastic element is disposed between the sliding ratchet and the crossbar and is sleeved on the outside of the rotating shaft.

[0018] In summary, this application has the following technical effects:

[0019] 1. By setting up an impeller and a limiter, the impeller is rotated by the wind. The airflow generated by the impeller rotation disturbs the wind, reducing the speed of the sand and reducing the sand's ability to carry dust. The limiter restricts the rotation direction of the impeller, and the impellers on adjacent crossbars rotate in opposite directions, making the turbulence generated by the impeller more chaotic, further reducing the wind speed of the sand and achieving good sand-blocking performance. At the same time, the turbulence is used to turbulently slow down the sand in advance, reducing the wind speed when the sand comes into contact with the sand-blocking wall, thereby increasing the service life of the sand-blocking wall.

[0020] 2. By installing telescopic sleeves, the normal operation of each component inside the limiter is protected, preventing the components from malfunctioning due to the intrusion of wind and sand, thus further improving the service life of the sand retaining wall.

[0021] 3. By setting up a cleaning device and a power supply device, wind power is used to generate electricity for storage. The stored electricity is then used to drive the sand-cleaning component to move back and forth between the two columns, so that the sand-cleaning component can clear the sand deposited between the two columns, thus preventing the sand retaining wall from being buried by accumulated sand and affecting its service life.

[0035] Reference Figure 6 An installation assembly 40 is provided between the crossbar 31 and the column 3. The installation assembly 40 is used to fix the crossbar 31 and the column 3. The installation assembly 40 includes an installation block 401 and a locking bolt 402. The installation block 401 has a first snap-fit ​​groove, and the column 3 has a second snap-fit ​​groove.

One end of the installation rod 50 is fixedly connected to the column 3, and the other end has a pointed tip that inserts into the ground.

[0036] The implementation principle of the embodiment of this application is as follows: When using the sand retaining wall, firstly, one end of the installation rod 50 is inserted into the ground, then the column 3 is moved and fixedly connected to the installation rod 50, then the horizontal bar 31 is moved between the two columns 3, then the horizontal bar 31 is moved to drive the first snap-fit ​​groove and the second snap-fit ​​groove to snap into each other, then the locking bolt 402 is threaded through the side wall of the first snap-fit ​​groove and connected to the column 3, then the horizontal bar 31 is fixed to the column 3, several horizontal bars 31 are installed in sequence, then the impeller 32 is installed on the horizontal bar 31, and the rotating shaft 33 of the impeller 32 passes through the horizontal bar 31 and is fixedly connected to the fixing ratchet 91 of the limiter 9.

[0037] When wind passes through impeller 32, the wind drives impeller 32 to rotate. The rotation of impeller 32 drives shaft 33 to rotate. The rotation of shaft 33 drives fixed ratchet 91 to rotate. When fixed ratchet 91 rotates, it pushes sliding ratchet 92 to slide along shaft 33. Sliding ratchet 92 pushes elastic element 93 to deform, thereby allowing fixed ratchet 91 to rotate. At the same time, sliding ratchet 92 drives sliding sleeve 102 to slide within fixed sleeve 101. Sliding sleeve 102 drives limiting strip 201 to slide within limiting groove 202. The cleaning brush 30 is used to... The impeller 32 cleans the sand and dust from the surface of the sliding sleeve 102; the airflow generated by the rotation of the impeller 32 disturbs the wind, reduces the speed of the sand and dust, and reduces the ability of the sand and dust to carry sand and dust. The impeller 32 is restricted to a certain direction of rotation by the limiter 9. At the same time, the impellers 32 on the adjacent crossbars 31 rotate in opposite directions, making the turbulence generated by the impeller 32 more chaotic, further reducing the wind speed of the sand and dust, and achieving good sand blocking performance. At the same time, the turbulence is used to turbulently slow down the sand and dust in advance, reducing the wind speed when the sand and dust come into contact with the sand-blocking wall, thereby improving the service life of the sand-blocking wall.

[0038] The rotation of the shaft 33 drives the micro generator 71 to rotate and generate electrical energy. After rectification by the rectifier, the electrical energy is stored in the battery 72. When it is necessary to clean the sand deposited between the windward side 1 and the leeward side 2, the electrical energy in the battery 72 is used to start the drive component 51 to rotate. The rotation of the drive component 51 drives the reciprocating screw 52 to rotate. The reciprocating screw 52 drives the slider 53 to slide along the length of the guide rod 6. The slider 53 drives the sand cleaning component 54 to reciprocate between the two columns 3 to clean the sand accumulated at the bottom of the sand retaining wall, so as to prevent the sand retaining wall from being buried by the sand and affecting the service life of the sand retaining wall.
