Description

Technical Field

[0001] This invention relates to the field of construction protection technology, and in particular to a slope protection device against rainfall. Background Technology

[0002] A slope is a sloping surface with a certain gradient created on both sides of a roadbed to ensure its stability. In recent years, my country has developed rapidly, and in the process of building a large number of railways, mines, ports, and water conservancy facilities, a large number of artificial slopes have inevitably been constructed. These slopes are likely to become unstable due to a lack of slope protection measures. Landslides caused by slope instability are known as one of the three major geological disasters in the world, along with earthquakes and volcanoes. Various landslide disasters can lead to serious consequences such as road traffic interruption, building collapse, and river blockage. Every year, my country suffers economic losses of billions of yuan due to various landslides. There are many factors that cause landslides, but landslides caused by rainfall account for 90% of the total number of landslides.

[0003] In my country, landslide prevention is the primary focus. Currently, the basic methods for preventing landslides mainly involve constructing various reinforcement projects such as retaining walls and anchoring, as well as various drainage projects, or ecological slope protection projects that utilize vegetation to stabilize the slope. However, for temporary slopes formed by excavation during construction, and for slopes of soil with a relatively fast infiltration rate, which are easily affected by rainfall, the traditional slope reinforcement technology using steel bars and concrete as the main materials is too expensive and has limited effectiveness. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a slope protection device against rainwater runoff, which solves the problem of slope instability and landslides caused by rainwater erosion.

[0005] According to an embodiment of the present invention, a slope rain protection device includes a support base, a support assembly, and a traction assembly. The support base is disposed at one end of a slope, and mounting plates are provided at both ends of the support base. A rotating shaft is rotatably disposed between the two mounting plates, and a rainproof cloth is wound on the rotating shaft. A drive motor is provided on the side wall of one of the mounting plates, and the output end of the drive motor is fixedly connected to the rotating shaft. There are several support assemblies, which are symmetrically arranged on both sides of the support base and along the slope.

One end of the traction assembly is connected to the free end of the rainproof cloth, and the other end of the traction assembly is connected to the rotating shaft. The rainproof cloth moves along the guide rail under the drive of the traction assembly.

[0006] Compared with the prior art, the present invention has the following beneficial effects: by setting a support base and mounting plate at one end of the slope, rolling a rainproof cloth on a rotating shaft between the two mounting plates, and setting a guide rail on the slope surface through a support component, when it rains, by starting the drive motor, the drive motor can drive the traction component to pull the free end of the rainproof cloth along the guide rail on the slope surface until the slope of that area is covered, thereby avoiding the problem of rainwater eroding the slope during heavy rain, causing slope instability and landslides.

[0007] Furthermore, the traction assembly includes limiting plates, which are respectively disposed at both ends of the rotating shaft. The rainproof cloth is located between the two limiting plates, and a winding groove is formed between each limiting plate and its adjacent mounting plate. Both ends of the free end of the rainproof cloth are fixedly connected to traction ropes. The other ends of the two traction ropes extend along the length direction of their corresponding guide rails and then pass around the bottom of the guide rails to connect with the rotating shaft in the corresponding winding groove.

[0008] Furthermore, it also includes: a rain collection tube, which is fixedly installed on the top of one of the mounting plates, a pressure sensor is fixedly installed inside the rain collection tube, a through groove is opened on the side wall of the rain collection tube, and a dense mesh plate is installed at the through groove, and the pressure sensor is electrically connected to the drive motor.

[0009] Furthermore, a rain collection funnel is provided at the top of the rain collection cylinder.

[0010] Furthermore, a filter screen is installed at the connection between the rain collection tube and the rain collection funnel.

[0011] Furthermore, each mounting plate has a mounting groove on its side wall facing the guide rail, and a gear is rotatably installed in the mounting groove. A mounting rod is fixedly installed on the side wall facing the gear and the free end of the mounting rod extends out of the mounting groove. A rotating rod is rotatably installed between two mounting rods. An adjustment component for adjusting the tilt angle of the mounting rod is also provided on the side wall of one of the mounting plates.

[0022] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1As shown in Figure 2, this embodiment of the invention proposes a slope rain protection device, including a support base 1, a support assembly, and a traction assembly. The support base 1 is located at one end of a slope 25, and mounting plates 2 are provided at both ends of the support base 1. A rotating shaft 3 is rotatably provided between the two mounting plates 2. A rainproof cloth 4 is wound on the rotating shaft 3. A drive motor 5 is provided on the side wall of one of the mounting plates 2, and the output end of the drive motor 5 is fixedly connected to the rotating shaft 3. There are several support assemblies, which are symmetrically arranged on both sides of the support base 1 and along the slope 25. Each support assembly has a guide rail 6 at its top, and the guide rails 6 are all L-shaped. One end of the traction assembly is connected to the free end of the rainproof cloth 4, and the other end of the traction assembly is connected to the rotating shaft 3. The rainproof cloth 4 moves along the guide rail 6 under the drive of the traction assembly. The support components are multiple and can be spliced ​​according to the slope length of the slope 25, making it more convenient to transport. The drive motor 5 can be powered by an external power source, a battery, or a solar panel 24 mounted on top of the two mounting plates 2. The solar panel 24 powers the drive motor 5. In case of heavy rain, the drive motor 5 is started, releasing the rainproof cloth 4 rolled up on the rotating shaft 3. At the same time, the traction component pulls the rainproof cloth 4 along the length of the guide rail 6 until the rainproof cloth 4 covers the slope 25, thus preventing the slope 25 from being washed away by heavy rain, ensuring the stability of the slope 25 structure, and preventing landslides. Since the guide rail 6 is supported by the support components, the rainproof cloth 4 can cover the slope 25 without damaging the vegetation planted on the slope 25, effectively protecting the growth of the vegetation. When the slope 25 does not need to be covered, the motor rotates in the reverse direction, causing the rotating shaft 3 to roll up the rainproof cloth 4 again.

[0024] like Figure 1As shown in Figure 3, the traction assembly further includes a limiting plate 7, which is respectively disposed at both ends of the rotating shaft 3. The rainproof cloth 4 is located between the two limiting plates 7. Each limiting plate 7 forms a winding groove with its adjacent mounting plate 2. Both ends of the free end of the rainproof cloth 4 are fixedly connected to a traction rope 8. The other end of the two traction ropes 8 extends along the length direction of their corresponding guide rail 6 and passes around the bottom of the guide rail 6 to connect with the rotating shaft 3 in the corresponding winding groove. In this embodiment, there are two traction ropes 8, which are fixedly connected to the two ends of the free end of the rainproof cloth 4. When the drive motor 5 rotates, the motor drives the rotating shaft 3 to rotate, so that the rainproof cloth 4 rolled on the rotating shaft 3 is released. At the same time, the rotating shaft 3 will roll up the traction ropes 8, so that the traction ropes 8 are rolled up in the winding groove formed by the limiting plate 7 and the mounting plate 2. When the traction ropes 8 are rolled up, they will pull the rainproof cloth 4 to move along the guide rail 6, so that the rainproof cloth 4 can cover the area and prevent the slope 25 from being eroded by more than 100°C. Preferably, a connecting rod is provided on the free end of the rainproof cloth 4 along its width direction. The two ends of the connecting rod are laid on two symmetrically arranged guide rails 6, so as to prevent the free end of the rainproof cloth 4 from collapsing. Furthermore, in order to make the movement of the traction rope 8 along the guide rail 6 to pull the rainproof cloth 4 more smoothly, guide wheels can be set at the end of the guide rail 6 farthest from the pivot 3 and at the bottom of each guide rail 6, which will facilitate the movement of the traction rope 8 and reduce the wear on the traction rope 8.

[0025] like Figure 1As shown in Figure 5, further comprising: a rain collection cylinder 9, which is fixedly mounted on the top of one of the mounting plates 2; a pressure sensor 10 fixedly mounted inside the rain collection cylinder 9; a through groove is formed on the side wall of the rain collection cylinder 9, and a dense mesh plate 11 is provided at the through groove; the pressure sensor 10 is electrically connected to the drive motor 5. To enable this device to automatically cover the slope 25 during rain, a rain collection cylinder 9 is installed on one of the mounting plates 2. When it rains, rainwater drips into the rain collection cylinder 9, and the rainwater in the rain collection cylinder 9 exerts pressure on the pressure sensor 10. When the rainwater in the rain collection cylinder 9 accumulates to a certain level until it reaches the threshold of the pressure sensor 10, the pressure sensor 10 transmits an electrical signal to the drive motor 5, causing the drive motor 5 to start working, thereby covering the slope 25 with the rainproof cloth 4. To prevent water accumulation in the rain collection cylinder 9 from affecting the pressure sensor 10's erroneous readings during intermittent light rain, a fine-mesh mesh 11 is installed on the side wall of the rain collection cylinder 9. This allows the water to flow out slowly, ensuring that the pressure sensor 10 only activates when a large amount of rainwater accumulates within a unit of time, exceeding a set threshold. The mesh 11 also eliminates the need for manual emptying of the rain collection cylinder 9, saving time and effort. Preferably, a layer of sponge can be placed on the side wall of the mesh 11 to further slow the outflow of rainwater from the rain collection cylinder 9, preventing the water from flowing out too quickly and failing to reach the set threshold of the pressure sensor 10. It should be noted that the circuit structure and controller required for the pressure sensor 10 to transmit electrical signals to the motor and start the motor are existing technologies and will not be elaborated upon here.

[0026] like Figure 5 As shown, a rain collection funnel 12 is further provided on the top of the rain collection cylinder 9. Since rainwater often does not fall vertically to the ground, but rather at an angle, by providing the rain collection funnel 12, the rain collection cylinder 9 can collect rainwater from a wider range, and prevent some rainwater from hitting the side wall of the rain collection cylinder 9 and failing to enter the rain collection cylinder 9 when it falls at an angle.

[0027] like Figure 1 and 5 As shown, a filter screen 13 is further provided at the connection between the rain collection cylinder 9 and the rain collection funnel 12. The filter screen 13 can prevent surrounding leaves from entering the rain collection cylinder 9 and affecting the accuracy of the pressure sensor 10.

[0028] like Figure 4 and 6As shown, furthermore, each mounting plate 2 has a mounting groove on its side wall facing the guide rail 6. A gear 15 is rotatably mounted in each mounting groove. A mounting rod 14 is fixedly mounted on the side wall of the gear 15 facing the guide rail 6. The free ends of the mounting rods 14 extend out of the mounting grooves. A rotating rod 16 is rotatably mounted between the two mounting rods 14. An adjustment assembly for adjusting the tilt angle of the mounting rod 14 is also provided on the side wall of one of the mounting plates 2. To make the movement of the rainproof cloth 4 onto the guide rail 6 smoother, the mounting rod 14 is released through the adjustment assembly. The worker rotates the mounting rod 14 to adjust the horizontal height of the rotating rod 16. After adjusting the horizontal height of the rotating rod 16 to a suitable position, the adjustment assembly locks the tilt angle of the mounting rod 14. By draping the rainproof cloth 4 over the rotating rod 16 that rotates between the two mounting rods 14, the traction rope 8 can move more smoothly and easily when released from the rotating shaft 3 and into the guide rail 6.

[0029] like Figure 6 As shown, the adjustment component further includes: a pin 17, a groove is provided on the side wall of the mounting groove, the pin 17 is slidably disposed in the groove, a drive plate 18 is fixedly sleeved on the side wall of the pin 17, a spring 19 is provided between the drive plate 18 and the side wall of the groove, one end of the pin 17 away from the groove is adapted to the tooth shape of the gear 15, and the other end of the pin 17 extends out of the groove and is provided with a handle 20. When released, pulling the handle 20 moves the pin 17 outward from the mounting plate 2, thereby retracting the pin 17 into the groove, and the pin 17 is no longer inserted into the tooth gap of the gear 15. At this time, the mounting rod 14 can be rotated, and after adjusting the horizontal height of the rotating rod 16 to a suitable position, the handle 20 is released, so that the pin 17 is re-inserted into the tooth gap of the gear 15, restricting the rotation of the gear 15. Preferably, a slot can be provided on the inner wall of the mounting groove away from the groove, so that the pin 17 is inserted into the slot, thereby making the restriction of the pin 17 on the rotation of the gear 15 more stable.

[0030] like Figure 1 and 2 As shown, the supporting component is a telescopic rod 21, with a tapered tip at the bottom. Due to the varying plant heights on different slopes 25, the telescopic rod 21's extendable nature allows for adaptive adjustment of the guide rail 6, broadening the applicability of the device. Fine-tuning the guide rail 6's height coordinates with the horizontal height of the rotating rod 16, ensuring smoother movement of the rainproof cloth 4. The tapered bottom of the telescopic rod 21 facilitates its insertion into the soil of the slope 25. The telescopic rod 21 and its extension method are existing technologies; a simpler approach is to use an inner and outer sleeve sliding connection secured with bolts, which will not be elaborated upon here.

[0031] like Figure 3and 4 As shown, furthermore, both ends of the sidewall of the guide rail 6 are provided with a locking plate 22 and a retaining sleeve 23. Adjacent guide rails 6 are connected to each other by the retaining sleeve 23 and the locking plate 22. Multiple guide rails 6 are connected to each other by the locking plate 22 and the retaining sleeve 23 provided on them. Specifically, the locking plate 22 on one guide rail 6 is inserted into the retaining sleeve 23 on the sidewall of another guide rail 6. This locking method not only makes the connection between multiple guide rails 6 more stable, but also ensures that multiple guide rails 6 are in the same straight line without steps, which is conducive to the smooth movement of the rainproof cloth 4 pulled by the traction rope 8 on the guide rail 6.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
