Description

Technical Field

[0001] The invention relates to the technical field of debris flow prevention and control, and in particular to a fully lined debris flow drainage channel based on multi-stage rotation energy dissipation. Background Art

[0002] A debris flow refers to a special flood containing a large amount of solid components caused by large-scale rainfall and other factors in mountainous areas. Because of its high density, fast movement speed, long migration distance and strong destructive ability, it often causes huge property losses and casualties.

[0003] Therefore, an effective retaining structure is developed to reduce the velocity and kinetic energy of debris flow, thereby reducing the distance and impact force of debris flow, and reducing the degree and scope of disaster. In the prior art, pile group type retaining structure is an effective means. This structure sets up a pile array in the debris flow area. When the debris flow passes through the pile group, an earth arch structure is formed between the piles. In the interaction between the debris flow and the pile group, the earth arch structure is constantly formed, destroyed, and rebuilt, causing flow energy loss, thereby achieving the purpose of disaster reduction and protection.

[0004] Although the pile structure can block debris flow to a certain extent, the piles are usually fixed when blocking debris flow and cannot interact with each other, resulting in poor blocking and energy dissipation effects and low efficiency. In addition, since the piles on the front side are subject to the greatest impact force, the front row of piles are damaged under the long-term impact of the debris flow on the front row of piles. After the front row of piles are damaged, the rear row of piles are subjected to the greatest impact force, which is not conducive to protecting the front row of piles while dissipating energy and diverting the debris flow, thereby reducing the service life of the piles and increasing the maintenance cost of the piles.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The debris flow is diverted by setting up the primary diverter and the secondary diverter, so that the debris flow with huge energy is separated into multiple debris flows with smaller energy, thereby achieving the purpose of weakening the impact on the primary rotating pile and the primary transmission parts.

[0017] 2. The rotation of the primary rotating pile and the primary transmission member is utilized to weaken a portion of the kinetic energy of the debris flow in the middle, and the positions of the primary rotating pile and the primary transmission member and the secondary rotating pile and the secondary transmission member are arranged so that the mechanical rotational force generated by the secondary rotating pile and the secondary transmission member can interact with the impact force of the two debris flows on both sides to generate a counter-attack, thereby consuming the kinetic energy of the debris flow.

[0018] 3. The rotation of the secondary rotating pile and the secondary transmission member is used to consume the kinetic energy of the side debris flow. The guide member can guide the debris flow and deflect the guided debris flow, thereby causing mutual impact with the debris flow after diversion, thereby weakening the kinetic energy of the debris flow.

[0019] 4. By setting up the convection groove of the counter-energy dissipation member, the debris flow guided by the guide member and the debris flow diverted by the secondary diversion member can be offset in the convection groove, thereby greatly consuming the kinetic energy of the debris flow. At the same time, the counter-energy dissipation member can always cover the guide groove, so that no impurities will enter the guide groove.

[0020] 5. The protruding part of the counter-energy dissipation component can promote the debris flow to reverse the counter-energy dissipation effect while the counter-energy dissipation component moves horizontally, and at the same time plays a guiding role. The lateral movement of the counter-energy dissipation component can not only promote the debris flow on the side to shake, but also confuse the movement direction of the debris flow in the convection trough, thereby achieving the effect of consuming the vertical kinetic energy of the debris flow.

[0021] 6. By moving the counter-energy dissipation parts relative to or away from each other, the distance between the two counter-energy dissipation parts can be changed intermittently, so that when there is a greater need to pass, it can pass smoothly. And through intermittent movement, the debris flow can have greater resistance when moving, thereby achieving the purpose of energy dissipation again.

[0022] 7. By setting up a swingable guide member, corresponding adjustments can be made as the counter-energy dissipation member moves, so that the debris flow at the diversion point and the debris flow at the diversion point can be increased or decreased at the same time when they are discharged into the convection trough, so that the debris flow at the two places will not be too large on one side and too small on the other side, so as to achieve a better counter-energy dissipation effect, avoid uneven counter-energy dissipation during the counter-energy dissipation process, and adapt to the flow changes during the debris flow discharge process.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] As the first embodiment of the present invention, although the pile structure can block the debris flow to a certain extent, when the pile body is blocking the debris flow, the pile body on the front side is subjected to the greatest impact force. Under the long-term impact of the debris flow on the pile body in the front row, the pile body in the front row is damaged. After the front row of piles is damaged, the pile body in the rear row is subjected to the greatest impact force, which is not conducive to protecting the front row of piles while dissipating energy and diverting the debris flow, thereby reducing the service life of the pile body and increasing the maintenance cost of the pile body.

[0039] In order to solve the above technical problems, please refer to the attached drawings of the specification. Figures 1 to 8 and Fig.12 It can be obtained that the first embodiment of the present invention provides a fully lined debris flow drainage channel based on multi-stage rotational energy dissipation, including a drainage channel body 1, one end of which is fixedly provided with a rear cover 101, and also includes a diversion component 2, a rotational energy dissipation component 3 and a diversion component 4, the diversion component 2 includes a primary diversion component 21 and a secondary diversion component 22 arranged on the drainage channel body 1, which are used to divert the debris flow step by step and weaken the kinetic energy of the debris flow, the rotational energy dissipation component 3 is arranged on the drainage channel body 1 and is located between the primary diversion component 21 and the secondary diversion component 22, which is used to rotate the debris flow.

The first-stage flow diversion assembly 21 comprises two first-stage flow diversion members 211 fixedly arranged on both sides of the drainage groove body 1, and the second-stage flow diversion member 22 is fixedly arranged on the drainage groove body 1. The two first-stage flow diversion members 211 and the second-stage flow diversion member 22 have pointed ends, and the pointed ends of the first-stage flow diversion member 211 and the second-stage flow diversion member 22 are both facing the opposite direction of the flow of the debris flow, so as to reduce the impact force on the first-stage flow diversion member 211 and the second-stage flow diversion member 22. The rotating energy dissipation assembly 3 comprises a first-stage flow diversion member 211 fixedly arranged on both sides of the drainage groove body 1, and the second-stage flow diversion member 22 is fixedly arranged on the drainage groove body 1. 1, the first-stage rotation energy dissipation component 31 and the second-stage rotation energy dissipation component 32 are arranged on the row guide groove body 1, the first-stage rotation energy dissipation component 31 includes two first-stage rotation piles 311 arranged on the row guide groove body 1, one end of the two first-stage rotation piles 311 are inserted into the row guide groove body 1 and are rotatably connected with the row guide groove body 1, and a plurality of first-stage transmission members 312 are fixedly arranged on the circumferential surface of the side not inserted into the row guide groove body 1 on each first-stage rotation pile 311, and a first pulley 313 is rotatably arranged on the end of each first-stage rotation pile 311 inserted into the row guide groove body 1, and the first pulley 313 is located between the rear cover 101 and the row guide groove body 1 and is rotatably connected with the rear cover 101, and the second-stage rotation energy dissipation component 31 includes two first-stage rotation piles 311 arranged on the row guide groove body 1, and one end of the two first-stage rotation piles 311 is inserted into the row guide groove body 1, and is rotatably connected with the rear cover 101, and the second-stage rotation energy dissipation component 31 includes two first-stage rotation piles 311 arranged on the row guide groove body 1, and the first pulley 313 is located between the rear cover 101 and the row guide groove body 1 ..., and is rotatably connected with the rear cover 101, and the second-stage rotation energy dissipation component 31 includes two first The energy component 32 includes two secondary rotating piles 321 arranged on the row guide groove body 1, one end of the two secondary rotating piles 321 are inserted into the row guide groove body 1 and are rotatably connected to the row guide groove body 1, and a plurality of secondary transmission parts 322 are fixedly provided on the circumferential surface of each secondary rotating pile 321 on the side not inserted into the row guide groove body 1, and a second pulley 323 is rotatably provided on the end of each secondary rotating pile 321 inserted into the row guide groove body 1, and the second pulley 323 is located between the rear cover 101 and the row guide groove body 1 and is rotatably connected to the row guide groove body 1, and each first pulley 313 is connected to the corresponding second pulley 323 through a transmission belt 314.

[0040] During specific use, first install each component on the drain guide trough body 1, a plurality of mounting holes are opened on the rear cover 101, and a plurality of mounting columns corresponding to the mounting holes are provided on the drain guide trough body 1, and then the mounting holes on the rear cover 101 and the mounting columns of the drain guide trough body 1 are matched, and then the rear cover 101 is fixedly connected to the drain guide trough body 1 and installed to the corresponding position. The drain guide trough body 1 is a method of connecting multiple drain guide trough bodies 1 so as to fully dissipate energy and divert debris flows. This connection method is a prior art and will not be described in detail here.

[0041] When a debris flow disaster occurs, the debris flow enters the debris flow drainage channel body 1 after being drained, and the debris flow first contacts the primary diverter 211. The primary diverter 211 can be provided with two on one drainage channel body 1. After the debris flow contacts the primary diverter 211, diversion occurs. The diversion effect is shown in the figure of the specification. Fig.12 As shown in the first-level flow diversion and energy dissipation part in the diagram, a debris flow with a large flow is divided into three smaller debris flows, wherein the debris flow in the middle part is greater than the flow of the two debris flows on both sides, and then the debris flow in the middle contacts the first-level rotating pile 311 and the first-level transmission member 312 of the first-level rotating energy dissipation component 31, and the debris flow pushes the first-level transmission member 312 to rotate around the axis of the corresponding first-level rotating pile 311, and the first-level transmission member 312 drives the first-level rotating pile 311 to rotate, and the two first-level rotating piles 311 rotate in opposite directions.

[0042] Part of the kinetic energy of the debris flow is converted into mechanical energy for the rotation of the first-level rotating pile 311 and the first-level transmission member 312, so that the kinetic energy of the debris flow is reduced, thereby avoiding excessive impact on the front-row pile body, which causes damage to the front-row pile body. At the same time, the debris flow is diverted by the diversion of the first-level diverter 211, thereby reducing the overall kinetic energy of the debris flow, and further reducing the impact force of the debris flow on the first-level rotating pile 311 and the first-level transmission member 312, thereby reducing the probability of the first-level rotating pile 311 and the first-level transmission member 312 being damaged.

[0043] When the primary rotating pile 311 rotates, the primary rotating pile 311 drives the second pulley 323 to rotate through the first pulley 313 and the transmission belt 314. The rotation of the pile body is shown in the figure of the specification. Fig.12 As shown in the first-level rotation energy dissipation and second-level rotation energy dissipation parts in the figure, the second pulley 323 drives the corresponding second-level rotating pile 321 and the second-level transmission member 322 to rotate. Since the two first-level rotating piles 311 are located at the inner and lower part of the first-level diverter 211, the debris flow in the middle after diversion can impact on the first-level rotating pile 311, so that the rotational force generated when the first-level rotating pile 311 rotates is relatively large. The two second-level rotating piles 321 are located at the outer and lower part of the first-level diverter 211, and the impact force of the debris flow on the side after diversion is relatively small. Therefore, the rotational force generated by the first-level rotating pile 311 can drive the second-level rotating pile 321 and the second-level transmission member 322 to rotate.

[0044] The rotation direction of the secondary rotating pile 321 and the secondary transmission member 322 is the same as the rotation direction of the corresponding primary rotating pile 311 and the primary transmission member 312. Due to the reasons for the setting positions, please refer to the drawings of the specification for details. Figures 1 to 5 and Fig.12 As shown, the debris flow guided by one group of guide members 401 is aligned with the secondary transmission members 322 on the two secondary rotating piles 321. The direction of the impact force generated by the debris flow there and the direction of the rotational force of the secondary rotating piles 321 can offset a part of it, thereby achieving the effect of dissipating the energy of the debris flow. Therefore, the secondary rotating piles 321 can impact the debris flow on the side after the diversion in the opposite direction, so that the debris flow on both sides is impacted in the opposite direction by the secondary rotating piles 321 and the secondary transmission members 322, thereby offsetting most of the kinetic energy of the debris flow on the side, and achieving the purpose of dissipating the energy of the debris flow.

[0045] When the debris flow continues to flow along the drainage channel body 1, the debris flow in the middle part contacts the secondary diverter 22 and diverts the debris flow there, dividing the larger debris flow in the middle into two smaller debris flows, where the debris flow is diverted and energy is dissipated. At the same time, after the debris flow contacts the secondary diverter 22, the diversion effect of the secondary diverter 22 is as shown in the accompanying drawings of the specification. Fig.12 As shown in the secondary flow dissipation position in the figure, due to the change in the moving direction, the impact force is divided into two directions along the shape of the secondary flow diverter 22. Both the primary flow diverter 211 and the secondary flow diverter 22 are triangular, and the tip is facing upward, as shown in the accompanying drawings of the specification. Figures 1 to 4 As shown, it is beneficial to divert and reduce the overall kinetic energy and guide the flow, so as to achieve the effect of dissipating the impact force of the debris flow.

[0046] At the same time, since multiple groups of guide members 401 are arranged on the drainage trough body 1, each group of guide members 401 is two guide members 401 arranged opposite to each other on the left and right, the debris flow after diversion can contact the side of the guide member 401 here, and after the impact occurs, the debris flow has a tendency to deviate, which has a certain impact on the flowing debris flow and consumes the kinetic energy of the debris flow. At the same time, the lateral impact force of the debris flow after diversion and the lateral impact force of the debris flow guided by the guide member 401 offset each other, and the impact force to the side is offset by the impact force next to it, thereby achieving multiple effects of energy dissipation.

[0047] The debris flow is diverted by the first-level diverter 211 and the second-level diverter 22, so that the debris flow with huge energy is separated into multiple debris flows with smaller energy, so as to achieve the purpose of weakening the impact on the first-level rotating pile 311 and the first-level transmission member 312, and play a protective effect on the front row of piles. The debris flow diverted by a group of guide members 401 is directed to the second-level transmission members 322 on the two second-level rotating piles 321, and at the same time, the rotation energy of the first-level rotating pile 311 and the first-level transmission member 312 is used to weaken the kinetic energy of a part of the middle debris flow, and the first-level rotating pile 311 and the first-level transmission member 312 are used to reduce the kinetic energy of the debris flow. The movable pile 311 and the primary transmission member 312 are arranged at the same positions as the secondary rotating pile 321 and the secondary transmission member 322 so that the mechanical rotation energy generated by the secondary rotating pile 321 and the secondary transmission member 322 can offset the kinetic energy of the debris flows on both sides. The rotation of the secondary rotating pile 321 and the secondary transmission member 322 is utilized to consume the kinetic energy of the debris flows on the sides. The guide member 401 is arranged to guide the debris flow and deflect the guided debris flow, thereby generating a mutual impact with the debris flow after diversion, thereby weakening the kinetic energy of the debris flow.

[0048] As the second embodiment of the present invention, on the basis of the above-mentioned embodiment one, rotational energy dissipation and diversion energy dissipation can achieve better energy dissipation effect. After rotation and diversion, although the debris flow is divided into multiple debris flows with smaller kinetic energy, the energy dissipation effect is still poor. There are some debris flows between the rotational energy dissipation components and the diversion energy dissipation components that have not been dissipated and still have large kinetic energy. Therefore, it is necessary to dissipate energy on the part that has not been dissipated after being divided into multiple parts.

[0049] In order to solve the above technical problems, based on the above embodiment 1, referring to the accompanying drawings of the specification Figures 1 to 12It can be seen that the adopted technical solution includes a drainage groove body 1, one end of which is fixedly provided with a rear cover 101, and also includes a counter-energy dissipation component 5, which is arranged at a position where the debris flow discharged by the guide component 4 and the diversion component 2 can be connected, so that the debris flow discharged from the guide component 4 and the diversion component 2 can produce convection, thereby reducing the flow energy of the debris flow at the end of the drainage groove body 1, and the counter-energy dissipation component 5 includes two counter-energy dissipation parts 501 arranged on both sides of the drainage groove body 1, each of which is provided with a convection groove 502, and the drainage groove body 1 is provided with two guide grooves 503 corresponding to the counter-energy dissipation parts 501, and the counter-energy dissipation parts 501 are provided with an insertion groove 503. A guide member 504 is arranged in the corresponding guide groove 503 and is able to slide in the guide groove 503. Two rotating members 505 corresponding to the counter-energy dissipation member 501 are rotatably provided on the guide groove body 1. A swing member 506 is arranged on the two rotating members 505. Each rotating member 505 is located in the middle of the corresponding swing member 506. The rotating member 505 is rotatably connected to the back cover 101. A clearance groove 507 is provided on both sides of each swing member 506 away from the rotating member 505. A plug column 508 inserted into the corresponding clearance groove 507 is eccentrically fixed on each second pulley 323. A plug rod 509 inserted into the corresponding clearance groove 507 is provided on each guide member 504.

[0050] During specific use, when the debris flow contacts the secondary diverter 22, diversion occurs. At the same time, the debris flow discharged from between one group of guide members 401 and the secondary rotating pile 321 and between the secondary rotating pile 321 and the secondary diverter 22, as well as the debris flow diverted on the secondary diverter 22, flows into the convection groove 502 of the counter-energy dissipation member 501 after diversion by the secondary diverter 22, and the debris flow discharged between the guide member 401 and the secondary rotating pile 321 also flows into the convection groove 502 of the corresponding counter-energy dissipation member 501. The two debris flows have opposite flow directions in the convection groove 502, and thus generate counter-flow in the convection groove 502, which greatly consumes the kinetic energy of the debris flow.

[0051] When the secondary rotating pile 321 rotates, the secondary rotating pile 321 drives the swinging member 506 to swing back and forth along the axis of the rotating member 505 in the rear cover 101 through the plug post 508 and the corresponding clearance groove 507. The position of the swinging member 506 on the rear cover 101 is as shown in the figure of the specification. Figure 5As shown, the rotating member 505 rotates on the drainage guide groove body 1 and the back cover 101, the swinging member 506 drives the corresponding plug rod 509 and the guide member 504 to move laterally through the yield groove 507, the guide member 504 moves in the corresponding guide groove 503, and the guide member 504 drives the counter-energy dissipation member 501 to move back and forth laterally in the drainage guide groove body 1, and at the same time, the counter-energy dissipation member 501 can always cover the guide groove 503, so that no impurities enter the guide groove 503, ensuring that the counter-energy dissipation member 501 can operate normally, and the lateral reciprocating movement of the counter-energy dissipation member 501 can not only promote the side debris flow to shake and collide, making the moving direction of the debris flow being shaken and collided chaotic, playing a certain energy dissipation role, but also can make the moving direction of the debris flow in the convection groove 502 chaotic, thereby achieving the purpose of consuming the vertical kinetic energy of the debris flow.

[0052] During this process, the two counter-energy dissipation components 501 always move laterally relative to or opposite to each other, and the opposite ends of the counter-energy dissipation components 501 have inclined protrusions, which can consume the kinetic energy of the debris flow when the debris flow changes direction while the counter-energy dissipation components 501 move laterally, and at the same time play a guiding role. The relative or opposite movement of the counter-energy dissipation components 501 can intermittently change the distance between the two counter-energy dissipation components 501, so that when there is a greater need to pass, it can pass smoothly. Through intermittent movement, the debris flow can be subjected to greater resistance when moving, thereby achieving the purpose of energy dissipation again.

[0053] By setting the convection groove 502 of the counter-energy dissipation member 501, the debris flow guided by the guide member 401 and the debris flow diverted by the secondary diverter member 22 can be offset in the convection groove 502, thereby greatly consuming the kinetic energy of the debris flow. At the same time, the counter-energy dissipation member 501 can always cover the guide groove 503, so that no impurities enter the guide groove 503. The protrusion of the counter-energy dissipation member 501 can promote the reversal of the debris flow to consume a certain amount of kinetic energy while the counter-energy dissipation member 501 moves horizontally, and at the same time plays a guiding role. The lateral movement of the counter-energy dissipation member 501 can not only cause the debris flow on the side to shake, but also confuse the movement direction of the debris flow in the convection trough 502, thereby achieving the effect of consuming the vertical kinetic energy of the debris flow. Through the relative or opposite movement of the counter-energy dissipation member 501, the distance between the two counter-energy dissipation members 501 can be intermittently changed, so that when there is a greater need to pass, it can pass smoothly, and through intermittent movement, the debris flow can be subjected to greater resistance when moving, thereby achieving the purpose of energy dissipation again.

[0054] As the third embodiment of the present invention, when the counter-energy dissipation components move relative to or opposite to each other, since the corresponding guide components cannot change accordingly with the movement of the counter-energy dissipation components, when most of the debris flow diverted by the secondary diverter component is discharged into the convection trough, the amount of debris flow diverted by the guide component is small, so that the counter-energy dissipation effect is less than ideal.

[0055] In order to solve the above technical problems, based on the above embodiments, referring to the accompanying drawings of the specification Figures 1 to 12It can be obtained that the adopted technical solution includes a drainage channel body 1, one end of which is fixedly provided with a rear cover 101, and also includes a guide assembly 4 and a counter-energy dissipation assembly 5. The guide assembly 4 includes a plurality of guide members 401 arranged on both sides of the drainage channel body 1, which are used to guide the debris flow. The counter-energy dissipation assembly 5 is arranged at a position that can connect the debris flow discharged by the guide assembly 4 and the diversion assembly 2, so that the debris flow discharged from the guide assembly 4 and the diversion assembly 2 generates convection, and reduces the kinetic energy of the debris flow at the end of the drainage channel body 1. A plurality of rotating shafts 402 corresponding to the guide members 401 are rotatably arranged in the drainage channel body 1, and one end of the rotating shaft 402 Inserted into the rear cover 101 and rotatably connected with the rear cover 101, the guide member 401 is fixedly connected to the corresponding rotating shaft 402, and one end of each rotating shaft 402 away from the guide member 401 is fixedly provided with a third pulley 403 located in the row guide groove body 1, the third pulley 403 is located between the rear cover 101 and the row guide groove body 1, and two adjacent third pulleys 403 are connected by a first connecting rope 404, and a second connecting rope 405 is fixedly provided on one side of the third pulley 403 close to the primary diverter 211, and air cylinders 406 corresponding to the second connecting rope 405 are respectively provided on both sides of the row guide groove body 1, and a sliding device 406 is provided in the air cylinder 406. There is a piston rod 407, one end of the piston rod 407 close to the third pulley 403 extends out of the air cylinder 406 and is fixedly connected to the free end of the second connecting rope 405, the counter-energy dissipation component 5 includes two counter-energy dissipation parts 501 arranged on both sides of the drainage guide groove body 1, each counter-energy dissipation part 501 is provided with a convection groove 502, the drainage guide groove body 1 is provided with a plurality of guide grooves 503 corresponding to the counter-energy dissipation parts 501, the counter-energy dissipation parts 501 are provided with guide parts 504 inserted into the corresponding guide grooves 503 and capable of sliding in the guide grooves 503, and a plurality of counter-energy dissipation parts 501 are rotatably provided on the drainage guide groove body 1. Corresponding rotating parts 505, two rotating parts 505 are provided with swinging parts 506, the rotating parts 505 are rotatably connected to the back cover 101, each swinging part 506 is provided with a clearance groove 507 on both sides away from the rotating part 505, each second pulley 323 is provided with a plug post 508 inserted into the corresponding clearance groove 507, each guide part 504 is fixedly provided with an insertion rod 509 inserted into the corresponding clearance groove 507, and a third connecting rope 510 is fixedly provided on one side of the guide part 504 close to the third pulley 403, and the free end of the third connecting rope 510 is fixedly connected to the third pulley 403 close to the guide part 504.

[0056] During specific use, when the two counter-energy dissipation members 501 move relative to each other, the counter-energy dissipation member 501 pulls the third connecting rope 510 inward through the guide member 504, and the corresponding third connecting rope 510 drives the third pulley 403 closest to the corresponding counter-energy dissipation member 501 to rotate. The third connecting rope 510 is wound around the third pulley 403, which can rotate the third pulley 403, and the third pulley 403 drives the corresponding rotating shaft 402 to rotate, and the rotating shaft 402 drives the corresponding guide member 401 to swing in the direction of movement of the counter-energy dissipation member 501, so that the debris flow guided by the guide member 401 can be discharged to the corresponding convection groove 502 to the maximum extent, and the counter-energy dissipation of the debris flow is as shown in the attached figure of the specification. Fig.12 As shown in the convection energy dissipation part, it is used to adapt to the phenomenon that when the convection groove 502 is close to the diversion part of the secondary diversion member 22, the mud-rock flow discharge at the diversion part increases, resulting in uneven impact and poor impact energy dissipation effect.

[0057] From the attached drawings of the specification Figures 1 to 4 ,and Figures 8 to 11 It is concluded that while the lowermost guide member 401 swings inward, the lowermost third pulley 403 drives the two upper third pulleys 403 to rotate in the opposite direction through the first connecting rope 404. The first connecting rope 404 is wound around the corresponding third pulley 403, and can drive the third pulley 403 to rotate, thereby increasing the gap between the two upper guide members 401 and the components on the guide groove body 1, increasing the flow rate of the debris flow there, thereby generating a better impact energy dissipation effect together with the diversion rate of the debris flow at the secondary diverter 22. At the same time, the uppermost third pulley 403 reels in the second connecting rope 405, and drives the piston rod 407 to move downward through the second connecting rope 405, and the gas between the piston rod 407 and the air cylinder 406 is compressed.

[0058] When the two counter-energy dissipation members 501 move in opposite directions, the convection groove 502 gradually moves away from the diversion point of the secondary diverter 22, and the flow rate of the debris flow discharged into the convection groove 502 decreases. At the same time, the guide member 504 no longer pulls the third connecting rope 510. Under the action of the compressed gas between the air cylinder 406 and the piston rod 407, the piston rod 407 moves in the opposite direction, and the piston rod 407 drives the corresponding third pulley 403 to rotate in the opposite direction through the second connecting rope 405. The third pulley 403 drives the corresponding two third pulleys 403 to rotate in the opposite direction through the first connecting rope 404, so that the gap between the two upper guide members 401 and the middle member is reduced, and the flow rate of the debris flow is reduced. The lowermost guide member 401 swings with the movement of the convection groove 502, so that the flow rates of the debris flow at the diversion point and the debris flow at the diversion point are reduced, so as to achieve better counter-energy dissipation effect and corresponding change effect, and avoid excessive or too small flow on one side, resulting in uneven counter-balancing.

[0059] By setting the swingable guide member 401, it is possible to make corresponding adjustments as the counter-energy dissipation member 501 moves, so that the debris flow at the diversion point and the debris flow at the diversion point can be increased or decreased at the same time when they are discharged into the convection groove 502, so that the debris flow at the two places will not be too large on one side and too small on the other side, so as to achieve better counter-energy dissipation effect, avoid uneven counter-energy dissipation during the counter-energy dissipation process, and adapt to the flow change during the debris flow discharge process.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
