DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and described below. For ease of interpretation and precise definition in the appended claims, the terms "upper", "lower", "inner" and "outer" are used to describe features of the exemplary embodiments shown in the drawings with reference to their positions.

[0026] An embodiment of the present invention provides a rock-blocking dam device for intercepting debris flow, comprising: a fixed plate 1 for being fixed on the surface of a mountain; a bracket 3 fixedly connected to the fixed plate 1; a perforated plate 401, a horizontal rotating shaft being provided at the lower end, the horizontal rotating shaft being fixedly connected to the bracket 3; an inclined panel 602, located at the front side of the perforated plate 401, a vertical rod 601 being provided at one end, the vertical rod 601 being perpendicular to the bracket 3; when intercepting debris flow, the angle between the inclined panel 602 and the perforated plate 401 is reduced.

[0027] Traditional rock-blocking dams are usually built with concrete or stone masonry. Once overload occurs, adaptive adjustment cannot be achieved, damage is easy to occur, and the construction is difficult and cannot be reused. The present invention provides a new type of rock-blocking dam for debris flow prevention and control with strong adaptive adjustment ability, simple structure, convenient construction, environmental protection and high repairability. When the debris flow rolls down to the surface of the inclined panel, the debris flow will slide down to the surface of the orifice plate through the slope of the inclined panel. The pores in the orifice plate are circular, that is, the orifice plate can be a circular hole protective plate to reduce the impact force on the circular hole protective plate and improve the stability of the circular hole protective plate when in use. In addition, the moisture in the debris flow will flow out through the circular holes in the circular hole protective plate to avoid a large amount of accumulated water accumulating on the surface of the circular hole protective plate.

[0028] According to an embodiment of the present invention, there are two inclined panels 602 , which are symmetrically arranged with the orifice plate 401 perpendicular to the center line of the bracket 3 as the axis, and the two inclined panels 602 are arranged away from each other at one end away from the vertical rod 601 .

[0029] According to an embodiment of the present invention, the device further includes: an extrusion rod 7, an extension frame 8, an elastic rod 9 and a fixing frame 10, wherein the fixing frame 10 is located at the rear side of the orifice plate 401, and includes: a first fixing frame, which is perpendicular to the orifice plate 401, and the first end of the first fixing frame is connected to the bracket 3; a second fixing frame, which is perpendicular to the bracket 3 and is arranged above the first fixing frame, and the first end of the second fixing frame is connected to the second end of the first fixing frame; a third fixing frame, which is perpendicular to the orifice plate 401, and the first end of the third fixing frame is connected to the second end of the second fixing frame; the elastic rod 9 is located at the rear side of the orifice plate 401 and perpendicular to the orifice plate 401, and the first end of the elastic rod 9 is connected to the second end of the third fixing frame; the extension frame 8 is located above the elastic rod 9, and includes: The first extension frame is perpendicular to the bracket 3, and the first end of the first extension frame is connected to the second end of the elastic rod 9; the second extension frame is in a U-shape and parallel to the bracket 3, and the side of the second extension frame away from the orifice plate 401 is connected to the second end of the first extension frame; the extrusion rod 7 is located above the extension frame 8, including: a first extrusion rod, perpendicular to the bracket 3, and the first end of the first extrusion rod is connected to the side of the second extension frame close to the orifice plate 401; the second extrusion rod, perpendicular to the orifice plate 401, and the first end of the second extrusion rod is connected to the second end of the first extrusion rod; the third extrusion rod, perpendicular to the bracket 3, the first end of the third extrusion rod is connected to the second end of the second extrusion rod, and the second end of the third extrusion rod is connected to the top center of the orifice plate 401. When the debris flow slides, the stones in the debris flow roll down to the top of the fixed plate 1 and contact the circular hole protection plate. After the circular hole protection plate is impacted, the connection between the extrusion rod 7 and the extension frame 8 is used to push the elastic rod 9 to deform, thereby utilizing the elasticity of the elastic rod 9 to reduce the impact force of the circular hole protection plate.

[0030] In the related art, traditional rock-blocking dam devices often face strong impacts of rocks and mud when dealing with debris flows. This impact will not only cause damage to the dam structure, but also affect the long-term stability and safety of the dam. In addition, most of the protective plates in the prior art are made of rigid materials and lack an elastic buffering mechanism, making it difficult to effectively absorb and disperse the impact force, causing the protective plates to easily break or deform under high-intensity impacts, thereby affecting the protective effect and life of the rock-blocking dam. In the embodiment of the present invention, an effective buffer system is formed by arranging an extrusion rod 7, an extension frame 8 and an elastic rod 9. Not only is the impact resistance of the rock-blocking dam improved, the service life of the protective plate is extended, but also the stability and reliability of the entire rock-blocking dam device are improved, which can more effectively protect the safety of downstream areas.

[0031] According to the embodiment of the present invention, the support 3 includes: a storage rack 301, located at the front side of the orifice plate 401; and sliding holes 302, which are provided on two side plates of the storage rack 301. The debris flow intercepted by the circular hole protection plate will fall to the inner wall of the storage rack 301 for storage, so as to prevent the intercepted debris flow from continuing to flow, and the water in the debris flow will flow out through the circular holes in the circular hole protection plate, so as to prevent a large amount of water from accumulating on the surface of the circular hole protection plate.

[0032] In the prior art, the intercepted debris flow will continue to flow due to the lack of an effective storage and drainage mechanism, causing secondary disasters. In addition, the traditional protective plate structural design cannot effectively separate the solids and liquids in the debris flow, resulting in the accumulation of moisture in the debris flow on the surface of the protective plate, which increases the weight and pressure of the device and easily causes structural damage and failure. In the embodiment of the present invention, an effective debris flow storage and drainage system is provided by setting a storage rack 301 and a sliding hole 302. When the debris flow is intercepted by the circular hole protective plate, the solid part of the debris flow will fall to the inner wall of the storage rack 301 for storage, which can prevent the intercepted debris flow from continuing to flow and reduce the risk of secondary disasters. At the same time, the moisture in the debris flow will flow out through the circular holes on the circular hole protective plate to prevent a large amount of water from accumulating on the surface of the protective plate.

[0033] According to an embodiment of the present invention, the device further includes: a lifting plate 501, a linkage rod 502, a pressure rod 503, an inclined plate 504, a push frame 505, and a stabilizing plate 506, wherein the lifting plate 501 is located above the storage rack 301 and is connected to the lower end of the orifice plate 401; the linkage rod 502 includes: a first linkage rod, a first end of which is vertically connected to a first side of the lifting plate 501; a second linkage rod, which is vertical to the orifice plate 401, a first end of which is connected to a second end of the first linkage rod; a third linkage rod, which is located at the rear side of the orifice plate 401 and is parallel to the orifice plate 401, a first end of which is connected to a second end of the second linkage rod; a fourth linkage rod, which is located at a rear side of the orifice plate 401 and is parallel to the orifice plate 401, a first end of which is connected to a second end of the second linkage rod; and a fourth linkage rod, which is located at a rear side of the orifice plate 401 and is parallel to the orifice plate 401. The first end of the movable rod is vertically connected to the second side of the lifting plate 501; the fifth connecting rod is perpendicular to the orifice plate 401, and the first end of the fifth connecting rod is connected to the second end of the fourth connecting rod; the sixth connecting rod is located on the rear side of the orifice plate 401 and is parallel to the orifice plate 401, and the first end of the sixth connecting rod is connected to the second end of the fifth connecting rod; the pressure rod 503 is fixedly connected between the third connecting rod and the sixth connecting rod; the inclined plate 504 is located on the rear side of the orifice plate 401, and the push frame 505 is installed on the upper end, and the push frame 505 is located below the pressure rod 503; the stabilizing plate 506 is located on the rear side of the orifice plate 401, contacts the surface of the orifice plate 401, and is connected to the push frame 505.

[0034] In the prior art, the impact force of the debris flow will cause the protective plate to tilt or move, thereby affecting the interception effect and the stability of the device, and may also cause damage to the device structure. In the process of debris flow accumulation, due to the lack of automatic adjustment and stabilization mechanism, the accumulated debris flow will increase the burden and damage risk of the device, thereby affecting the efficiency and reliability of the rock-blocking dam device. After the debris flow enters the interior of the storage rack 301, it pushes the lifting plate 501 to move downward. When the lifting plate 501 moves downward, it pushes the pressure rod 503 to move downward through the linkage rod 502. At this time, the pressure rod 503 will contact the push rack 505, and push the inclined plate 504 to move downward through the push rack 505. When the inclined plate 504 moves downward, it pushes the stabilizing plate 506 for extrusion to avoid the tilt of the circular hole protective plate causing the debris flow to slide. The present invention realizes the automatic stabilization of the protective plate through a series of linkage devices, avoids the problem of the tilt of the protective plate caused by the impact force of the debris flow, ensures the effective interception of the debris flow, and effectively disperses and transmits the impact force of the debris flow, reduces the force of a single structural member, and enhances the impact resistance of the entire device.

[0035] According to an embodiment of the present invention, the device also includes: two support plates 11, both located on the rear side of the orifice plate 401 and perpendicular to the orifice plate 401, the first end of each support plate 11 is fixedly connected to the edge of the fixed plate 1, the second end of each support plate 11 is fixedly connected to the bracket 3, and the two support plates 11 are symmetrically arranged with the fixed frame 10 as the center; two elastic extrusion rods 12, the first end of each elastic extrusion rod 12 is hinged to the first end of each support plate 11, and the second end of each elastic extrusion rod 12 is sleeved on the surface of the pressure rod 503.

[0036] The lifting plate 501 of the present invention has a lifting space due to the elasticity of the elastic rod 13 and the elastic extrusion rod 12, so that after the circular hole protection plate is impacted, it can still squeeze the elastic rod 9 to mitigate the impact.

[0037] According to an embodiment of the present invention, the device also includes: two bending rods 2, one end of each bending rod 2 is fixedly connected to the surface of the pressure rod 503, and the other end is connected to the corresponding vertical rod 601, and the two bending rods 2 are symmetrically arranged with the fixing frame 10 as the center.

[0038] According to an embodiment of the present invention, the device further comprises: an elastic rod 13 fixedly connected between the storage rack 301 and the lifting plate 501; there are three elastic rods 13, and two adjacent elastic rods 13 are arranged at the same distance.

[0039] In the prior art, when dealing with debris flow impacts, the rock-blocking dam device has problems with unstable supporting structure and insufficient impact absorption capacity. The traditional support structure design is easily deformed or damaged under the impact of debris flow, and cannot effectively absorb and disperse the impact force. In addition, the lack of an effective buffering mechanism makes the protective plate prone to failure when subjected to strong impacts, thereby affecting the protective effect and durability of the entire device. The embodiment of the present invention forms a stable and elastically buffered support structure by providing two support plates 11, two elastic extrusion rods 12 and three elastic rods 13, so that the circular hole protective plate can buffer and reduce shock when impacted, reducing damage to the protective plate and the entire device, thereby improving the protective effect of the rock-blocking dam device and extending the service life of the rock-blocking dam device.

[0040] According to the embodiment of the present invention, four corners of the surface of the fixing plate 1 are respectively provided with fixing holes 101 for mounting the fixing plate 1 on the surface of the mountain.

[0041] According to the embodiment of the present invention, there are two sliding holes 302 , and the two sliding holes 302 are symmetrically arranged with the orifice plate 401 being perpendicular to the center line of the bracket 3 as an axis.

[0042] The method of the present invention is further described in detail below in conjunction with specific implementation modes and drawings.

The present invention uses a fixing hole 101 to install the fixing plate 1 on the surface of the mountain. When the debris flow slides, the stones in the debris flow roll down to the top of the fixing plate 1 and contact the circular hole protection plate. After the circular hole protection plate is impacted, the extrusion rod 7 is used to squeeze the fixing plate 10. The connection between the pressure rod 7 and the extension frame 8 pushes the elastic rod 9 to deform, thereby utilizing the elasticity of the elastic rod 9 to reduce the impact force of the circular hole protection plate. The debris flow intercepted by the circular hole protection plate will fall to the inner wall of the storage rack 301 for storage, preventing the intercepted debris flow from continuing to flow. The moisture in the debris flow will flow out through the circular holes in the circular hole protection plate, preventing a large amount of accumulated water from accumulating on the surface of the circular hole protection plate.

After the debris flow enters the interior of the storage rack 301, it pushes the lifting plate 501 to move downward.

At this time, the pressure The force rod 503 will contact the push frame 505, and push the inclined plate 504 downward through the push frame 505. When the inclined plate 504 moves downward, it pushes the stabilizing plate 506 to squeeze, so as to prevent the circular hole protection plate from tilting and causing the mud-rock flow to slide. The lifting plate 501 has a lifting space due to the elasticity of the elastic rod 13 and the elastic squeezing rod 12, so that the circular hole protection plate can still squeeze the elastic rod 9 to reduce the impact after being impacted.

[0052] Figure 6 is a schematic diagram of the overall structure of a protective component according to an embodiment of the present invention, as shown in Figure 6As shown, the protective component 6 includes a bending rod 2, which is fixedly connected to the surface of the pressure rod 503, and one end of the bending rod 2 away from the pressure rod 503 is fixedly connected to a vertical rod 601. When the debris flow of the present invention rolls down to the top of the fixed plate 1, it will contact the surface of the inclined panel 602. The inclined panel 602 is used to reduce the impact of the debris flow. The debris flow will slide down to the surface of the circular hole protective plate through the slope of the inclined panel 602, further reducing the impact force on the circular hole protective plate and improving the stability of the circular hole protective plate when in use. The surface of the vertical rod 601 is fixedly connected to the inclined panel 602.

[0053] There are two bending rods 2, which are symmetrically arranged with the pressure rod 503 as the center. The vertical rod 601 is arranged at the end where the bending rod 2 and the lifting plate 501 are close to each other, and the ends of the two inclined panels 602 away from the circular hole protection plate are arranged to be far away from each other.

[0054] When in use, the fixing plate 1 is installed on the surface of the mountain using the fixing hole 101. When the debris flow slides, the stones in the debris flow roll down to the top of the fixing plate 1 and contact the circular hole protective plate. After the circular hole protective plate is impacted, the connection between the extrusion rod 7 and the extension frame 8 is used to push the elastic rod 9 to deform, thereby utilizing the elasticity of the elastic rod 9 to reduce the impact force of the circular hole protective plate. The debris flow intercepted by the circular hole protective plate will fall to the inner wall of the storage rack 301 for storage, thereby preventing the intercepted debris flow from continuing to flow.

[0055] The water in the debris flow will flow out through the circular holes in the circular hole protection plate to prevent a large amount of water from accumulating on the surface of the circular hole protection plate. After the debris flow enters the storage rack 301, it pushes the lifting plate 501 to move downward. When the lifting plate 501 moves downward, it pushes the pressure rod 503 to move downward through the connecting rod 502.

[0056] At this time, the pressure rod 503 will contact the push frame 505, and push the inclined plate 504 downward through the push frame 505. When the inclined plate 504 moves downward, it pushes the stabilizing plate 506 to squeeze, so as to prevent the circular hole protection plate from tilting and causing the mud-rock flow to slide.

[0057] The lifting plate 501 has space for lifting and lowering due to the elasticity of the elastic rod 13 and the elastic squeezing rod 12, so that the round hole protection plate can still squeeze the elastic rod 9 to mitigate the impact after being impacted. When the debris flow rolls to the top of the fixed plate 1, it will contact the surface of the inclined panel 602. The inclined panel 602 is used to reduce the impact of the debris flow. The debris flow will slide to the surface of the round hole protection plate through the slope of the inclined panel 602, further reducing the impact force on the round hole protection plate and improving the stability of the round hole protection plate when in use.

[0058] The above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications may be made based on the following description, and these various changes, modifications, substitutions and deformations derived from the principles and spirit of the present invention still fall within the scope of protection of the present invention.
