Description

Technical Field

[0001] This utility model relates to the field of debris flow prevention and control technology, and in particular to a guide structure for debris flow prevention and control. Background Technology

[0002] Debris flows are torrents formed when rainstorms or floods saturate and dilute loose soil containing sand and gravel, causing enormous losses to people's lives and livelihoods. Therefore, it is necessary to take preventive and control measures against debris flows. Existing debris flow control interception structures have poor load-bearing capacity and are easily damaged.

[0003] The prior art (CN218027488U) discloses an interception structure for debris flow prevention, including a protective steel plate, a fixed base plate, a fixed support column, and a support base. The protective steel plate and the fixed support column are tightly connected together by fixing screws, which facilitates connection, installation, and disassembly, and the connection is firm. The load-bearing capacity of the device is improved by connecting sleeves, connecting slide rods, and reinforcing base plates, which enhances the support of the protective steel plate, resulting in good prevention and control effects and reducing the damage caused by debris flows. The connection of the support base, fixed base plate, and reinforcing base plate to the ground is made more stable by inserting round rods, which improves the load-bearing capacity of the device.

[0004] However, using the above method will cause the protective steel plate to be damaged due to the falling rocks generated by the mudslide. This will result in the protective steel plate being damaged after multiple impacts without buffering, which will affect the subsequent interception effect. Utility Model Content

[0005] The purpose of this invention is to provide an interception structure for debris flow prevention, aiming to solve the problem that existing interception structures used in debris flow prevention suffer damage to the protective steel plate due to the falling rocks generated by debris flows directly impacting it, which in turn affects the subsequent interception effect.

[0007] The buffer assembly includes two auxiliary buffer structures, a buffer frame, two unloading rods, an unloading plate, an unloading component, a transmission seat, and a buffer plate;

[0008] Two auxiliary buffer structures are respectively disposed on one side of the protective steel plate; the buffer frame is fixedly connected to the protective steel plate and located on one side of the protective steel plate; two unloading rods are respectively fixedly connected to the buffer frame and located inside the buffer frame; the unloading plate is slidably connected to the two unloading rods and located on one side of the two unloading rods; the unloading component is respectively disposed between the buffer frame and the unloading plate; the transmission seat is fixedly connected to the unloading plate and located on one side of the unloading plate; the buffer plate is fixedly connected to the transmission seat and located on one side of the transmission seat.

The first damper is fixedly connected to the rubber pad and to the first rod, and is located on one side of the rubber pad. The buffer spring is fixedly connected to both the first rod and the second rod, and is located between the first rod and the second rod.

[0011] The unloading component includes a second damper and an unloading spring. The second damper is fixedly connected to the buffer frame and the unloading plate, and is located between the buffer frame and the unloading plate. The unloading spring is fixedly connected to the buffer frame and the unloading plate, and is located between the buffer frame and the unloading plate.

[0012] The buffer assembly further includes an auxiliary blocking structure, which is disposed on one side of the fixed support column.

[0013] The auxiliary barrier structure includes two brackets, two fixing members, and a barrier member. The two brackets are fixedly connected to the two fixed support columns and are located on one side of the two fixed support columns respectively. The two fixing members are respectively disposed on one side of the two brackets. The barrier member is located on one side of the two fixing members.

[0014] The fixing component includes a fixing frame, an operating screw, a pressure plate, multiple limiting rods, and two guide rods.

[0016] This utility model discloses an interception structure for debris flow prevention. In use, the protective steel plate is fixed between two fixed support columns by multiple fixing bolts. Expansion screws, in conjunction with the two fixing plates, secure the fixed support columns to a suitable interception position. When a debris flow occurs, falling rocks impact the buffer plate. The buffer plate, possessing a certain degree of toughness, absorbs the impact force and transmits it to the unloading plate through multiple transmission seats. The unloading plate slides on two unloading rods, absorbing the impact force in conjunction with the unloading components. Then, two auxiliary buffer structures located behind the protective steel plate further absorb the impact force and assist in supporting the protective steel plate, thereby mitigating the impact force generated by falling rocks. This solves the problem in existing debris flow prevention interception structures where, due to the falling rocks generated by debris flows, repeated impacts without buffering can damage the protective steel plate, thus affecting the subsequent interception effect.

[0027] This utility model discloses an interception structure for debris flow prevention, comprising two fixed support columns 101, two fixed plates 102, a protective steel plate 103, and a buffer assembly. The buffer assembly includes two auxiliary buffer structures 104, a buffer frame 105, two stress-relief rods 106, a stress-relief plate 107, a stress-relief component 108, a transmission seat 109, and a buffer plate 110. Each auxiliary buffer structure 104 includes a connecting seat 111, a first rod 112, a second rod 113, a buffer component 114, and a fixed seat 115. The buffer component 114 includes a rubber pad 116, a first damper 117, and a buffer spring 118. The stress-relief component 108 includes a second damper 119 and a... The unloading spring 120 and the buffer assembly also include an auxiliary blocking structure. The auxiliary blocking structure includes two brackets, two fixing parts, and a blocking part. The fixing parts include a fixing frame, an operating screw, a pressure plate, multiple limiting rods, and two guide rods. The fixing frame 125 has multiple limiting holes. The blocking structure includes two mounting plates and a plastic steel mesh. The mounting plate 130 has multiple through holes. The aforementioned solution solves the problem that existing interception structures used in debris flow prevention and control suffer damage to the protective steel plate 103 due to falling rocks caused by debris flows. This damage, in turn, affects the subsequent interception effect.

[0028] In this specific embodiment, the two fixing plates 102 are respectively disposed on one side of the two fixing support columns 101; the protective steel plate 103 is respectively disposed between the two fixing support columns 101, and the protective steel plate 103 is fixed between the two fixing support columns 101 by multiple fixing bolts, and the fixing support columns 101 are fixed in a suitable cutting position by using expansion screws in conjunction with the two fixing plates 102.

[0029] Furthermore, the two auxiliary buffer structures 104 are respectively disposed on one side of the protective steel plate 103; the buffer frame 105 is fixedly connected to the protective steel plate 103 and located on one side of the protective steel plate 103; the two unloading rods 106 are respectively fixedly connected to the buffer frame 105 and are respectively located inside the buffer frame 105; the unloading plate 107 is slidably connected to the two unloading rods 106 and is located on one side of the two unloading rods 106; the unloading component 108 is respectively disposed between the buffer frame 105 and the unloading plate 107; the transmission seat 109 is fixedly connected to the unloading plate 107 and is located on one side of the unloading plate 107; the buffer plate 110 is fixedly connected to the transmission seat 109 and is located on one side of the transmission seat 109, when mud... When a debris flow occurs, falling rocks impact the buffer plate 110. The buffer plate 110, having a certain degree of toughness, absorbs the impact force and transmits it to the stress relief plate 107 through the transmission seat 109. The stress relief plate 107 slides on the two stress relief rods 106 in cooperation with the stress relief component 108 to absorb the impact force. Then, it works in conjunction with the two auxiliary buffer structures 104 set behind the protective steel plate 103 to absorb the impact force and assist in supporting the protective steel plate 103, thereby reducing the impact force generated by the falling rocks. This solves the problem of existing interception structures used in debris flow prevention where, because debris flows generate falling rocks, these rocks directly impact the protective steel plate 103. Therefore, repeated impacts without buffering can damage the protective steel plate 103, thus affecting the subsequent interception effect.

[0030] Furthermore, the connecting seat 111 is fixedly connected to the protective steel plate 103 and located on one side of the protective steel plate 103; the first rod 112 is fixedly connected to the connecting seat 111 and located on one side of the connecting seat 111; the second rod 113 is slidably connected to the first rod 112 and located on one side of the first rod 112; the buffer member 114 is respectively disposed between the first rod 112 and the second rod 113; the fixing seat 115 is fixedly connected to the second rod 113 and located on one side of the second rod 113. The connecting seat 111 is used to support the first rod 112 installed on the protective steel plate 103. The first rod 112 and the second rod 113 cooperate with the buffer member 114 to absorb and buffer the impact force transmitted from the protective steel plate 103. The fixing base is fixed to the ground by expansion bolts.

[0031] Furthermore, the rubber pad 116 is fixedly connected to the second rod 113 and located on one side of the second rod 113; the first damper 117 is fixedly connected to the rubber pad 116 and to the first rod 112, and located on one side of the rubber pad 116; the buffer spring 118 is fixedly connected to the first rod 112 and the second rod 113 respectively, and located between the first rod 112 and the second rod 113. When the impact force penetrates the protective steel plate 103, the first damper 117 utilizes the properties of the damper, in conjunction with the elastic absorption assistance of the buffer spring 118 and the rubber pad 116, to absorb and reduce the impact force, thereby reducing the impact force received by the protective steel plate 103 and further protecting the protective steel plate 103.

[0032] Furthermore, the second damper 119 is fixedly connected to the buffer frame 105 and the stress relief plate 107 respectively, and is located between the buffer frame 105 and the stress relief plate 107; the stress relief spring 120 is fixedly connected to the buffer frame 105 and the stress relief plate 107 respectively, and is located between the buffer frame 105 and the stress relief plate 107. The second damper 119 utilizes the properties of the damper, in conjunction with the elastic absorption assistance of the stress relief spring 120, to buffer the impact force transmitted from the stress relief plate 107 and reduce the impact force directly received by the protective steel plate 103.

[0033] Furthermore, the auxiliary barrier structure 121 is disposed on one side of the fixed support column 101. The auxiliary barrier structure 121 is used to assist in blocking falling rocks generated by debris flow landslides, thereby further increasing the protective effect.

[0034] Furthermore, the two brackets 122 are respectively fixedly connected to the two fixed support columns 101 and are respectively located on one side of the two fixed support columns 101; the two fasteners 123 are respectively disposed on one side of the two brackets 122; the blocking member 124 is located on one side of the two fasteners 123, and the two brackets 122 are used to support the two fasteners 123 to assemble the blocking member 124.

[0035] Furthermore, the fixing frame 125 is fixedly connected to the bracket 122 and located on one side of the bracket 122; the plurality of limiting holes 132 are respectively located on one side of the fixing frame 125; the operating screw 126 is threadedly connected to the fixing frame 125 and located on one side of the fixing frame 125; the pressure plate 127 is rotatably connected to the operating screw 126 and located on one side of the operating screw 126; the plurality of limiting rods 128 are respectively fixedly connected to the pressure plate 127 and are respectively located on one side of the pressure plate 127; the two guide rods 129 are respectively fixedly connected to the pressure plate 127 and slide against the fixing frame 125. The two ends of the barrier 124 are placed in the two fixed frames 125 respectively when assembling the barrier 124. Then, the operating screw 126 is operated to rotate the fixed frame 125, which drives the pressure plate 127 to cooperate with the guidance of the two guide rods 129. This allows the pressure plate 127 to drive the multiple limiting rods 128 to pass through the barrier 124 and insert into the limiting hole 132. Then, the pressure plate 127 abuts against the barrier 124 to complete the assembly of the barrier 124, making the assembly or disassembly of the barrier 124 more convenient.

[0036] Furthermore, the two assembly plates 130 are respectively located on one side of the two fixed frames 125; the plurality of through holes 133 are respectively located on one side of the assembly plate 130; the plastic steel mesh 131 is fixedly connected to the two assembly plates 130 and located between the two assembly plates 130. When assembling the plastic steel mesh 131, the assembly plates 130 on both sides of the plastic steel mesh 131 are respectively placed on the two fixed frames 125, the plurality of through holes 133 are respectively aligned with the plurality of limiting holes 132, and then the limiting rod 128 is driven by the pressure plate 127 to fix the assembly plate 130, thereby completing the assembly of the plastic steel mesh 131.

[0037] When using this utility model, during the assembly of the blocking member 124, place both ends of the blocking member 124 into the two fixed frames 125 respectively. Then, operate the operating screw 126 to rotate the screw thread of the fixed frame 125, driving the pressure plate 127 to cooperate with the guidance of the two guide rods 129. This causes the pressure plate 127 to drive multiple limiting rods 128 through the blocking member 124 and insert them into the limiting holes 132. Then, the pressure plate 127 abuts against the blocking member 124 to complete the assembly of the blocking member 124. The blocking member 124 is used to assist in blocking falling rocks generated by debris flow landslides, further increasing the protective effect. When a debris flow occurs, the falling rocks hit the buffer plate 110. The buffer plate 110 has a certain toughness and absorbs the impact force, which is then transmitted through the conduction seat 109. The unloading plate 107 slides on the two unloading rods 106 in conjunction with the unloading component 108 to absorb the impact force. The second damper 119, utilizing the properties of the damper, works in conjunction with the elastic absorption of the unloading spring 120 to buffer the impact force transmitted from the unloading plate 107, reducing the direct impact force received by the protective steel plate 103. Then, it works in conjunction with the two auxiliary buffer structures 104 set behind the protective steel plate 103 to absorb the impact force and assist in supporting the protective steel plate 103, thereby reducing the impact force generated by falling rocks. This solves the problem that existing interception structures used in debris flow prevention and control often result in damage to the protective steel plate 103 due to falling rocks that directly impact it, thus affecting the subsequent interception effect.
