Abstract
Description
Technical Field
[0001] This invention relates to the field of geological disaster monitoring technology, and in particular to an impact-resistant debris flow impact force monitoring device. Background Technology
[0002] Debris flows possess immense impact force and destructive power, damaging various obstacles along their path or in their depositional areas through carrying, scouring, burying, and impact. They are a common and typical type of natural disaster in mountainous regions. To reduce losses caused by debris flows, it is necessary to monitor their impact force. Accurate monitoring of debris flow impact force can provide fundamental design parameters for debris flow prevention projects, and provide accurate data for calculating the anti-slip and anti-overturning properties of retaining structures. This ensures the safety and reliability of prevention projects and serves disaster prevention and mitigation in debris flow-prone areas.
[0003] However, the existing monitoring equipment has weak impact resistance and lacks an effective multi-level buffer structure. The boulders, sand and gravel carried by debris flows will exert a strong rigid impact on the monitoring device, which can easily cause deformation or damage to the monitoring sensors and stress-bearing components. This makes the equipment unable to work properly or even completely fail when a debris flow occurs, and it will be unable to complete the effective collection of impact force data.
[0004] In view of this, we have studied and improved the existing problems to provide an impact-resistant debris flow impact force monitoring device, aiming to solve the problems and improve its practical value through this technology. Summary of the Invention

A baffle is fixedly connected to one end of each support rod, and a laser displacement sensor is mounted on the other end via a connecting block. A scale that cooperates with the laser displacement sensor is fixedly connected to the fixed plate. A buffer mechanism is provided, comprising an elastic buffer unit and a hydraulic buffer unit disposed between the fixed plate and the baffle. The hydraulic buffer unit includes a hydraulic cylinder hinged to the fixed plate and a buffer rod B hinged to the baffle and slidably engaged with the hydraulic cylinder. A piston is provided at one end of the buffer rod B inside the hydraulic cylinder, and a spring B is sleeved on the buffer rod B. One end of the spring B abuts against a circular plate fixed on the buffer rod A. A pressure sensor for detecting buffer pressure is provided between the hydraulic cylinder and the circular plate. A solenoid valve electrically connected to the pressure sensor is provided on the piston to adjust the buffer damping according to the magnitude of the impact force. An air blowing mechanism, which is connected to an elastic buffer unit, is used to spray gas onto the laser displacement sensor and the scale. The cleaning mechanism includes an arc-shaped plate rotatably disposed on one side of the baffle, and a power component disposed on one side of the fixed plate. The power component is used to drive the baffle to reset and cause the arc-shaped plate to flip relative to the baffle.
[0007] Preferably, a photovoltaic panel is fixedly installed on the outer wall of the monitoring pile, the photovoltaic panels are symmetrically distributed on both sides of the monitoring pile, and the installation height of the photovoltaic panel is higher than that of the fixed plate.
[0008] Preferably, the elastic buffer unit includes multiple sets of sleeves fixed to one side of the fixed plate. A buffer rod A fixed to the fixed plate slides inside the sleeve. A spring A is provided inside the sleeve. One end of the spring A is fixedly connected to the inner wall of the sleeve, and the other end is fixedly connected to one end of the buffer rod A.
[0009] Preferably, the blowing mechanism includes an air storage cylinder connected to one side of the elastic buffer unit, two sets of symmetrically arranged nozzles are fixedly installed on one side of the connecting block, a connecting pipe connects the air storage cylinder and the nozzles, one-way suction valves are installed at both ends of the air storage cylinder, and one-way exhaust valves are installed inside the connecting pipe.
[0010] Preferably, the nozzle of the connecting pipe near the nozzle is flat and faces the corresponding surfaces of the laser displacement sensor and the scale.
[0011] Preferably, the power component includes an electric cylinder mounted on one side of the fixed plate, a push rod fixedly connected to the output end of the electric cylinder, a through hole opened on the surface of the baffle, the push rod being inserted into the through hole, a rotating shaft fixedly connected to the top end of the arc-shaped plate, and a torsion spring fixedly connected between one end of the rotating shaft and the top end of the baffle.
[0012] Preferably, the two sets of arc-shaped plates are symmetrically distributed on both sides of the baffle, and the bottom end of the arc-shaped plates is flush with the bottom end of the baffle.
[0013] Preferably, the outer wall of the support rod is fitted with a guide sleeve, the guide sleeve is fixedly connected to the fixing plate, and the inner wall of the guide sleeve is provided with a lubricating coating, and the support rod and the guide sleeve are in sliding fit.
[0014] Preferably, the detection end of the laser displacement sensor is vertically aligned with the scale surface of the ruler, and the distance between the laser displacement sensor and the ruler is 1 to 2 centimeters. The surface of the ruler is coated with an anti-reflective coating.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a two-stage hydraulic buffer system. As the baffle moves backward, it drives the buffer rod B into the hydraulic cylinder. The piston at one end of the buffer rod B slides within the hydraulic cylinder, compressing the internal medium. This, combined with the elastic buffering effect of the spring B, forms a two-stage hydraulic buffer. Simultaneously, the sleeve slides relative to the buffer rod A, causing the spring A to undergo elastic deformation, forming a first-stage elastic buffer. The two-stage buffering structure works synergistically to weaken the strong impact load of the debris flow, preventing damage to the equipment due to rigid impact. Furthermore, during the buffering process, a pressure sensor continuously collects the pressure signal between the hydraulic cylinder and the circular plate. When the pressure reaches a preset threshold, the pressure sensor and the solenoid valve are electrically linked, causing the solenoid valve to automatically open and adjust the internal damping of the hydraulic cylinder, achieving adaptive buffering and ensuring stable operation of the equipment under debris flow conditions of varying intensities.
[0016] 2. This invention utilizes the backward displacement of the baffle under the impact of a debris flow. This displacement is synchronously transmitted to the support rod, which in turn drives the connecting block to move synchronously. The laser displacement sensor mounted on the surface of the connecting block also moves synchronously. At this time, the detection end of the laser displacement sensor is always vertically aligned with the scale on the outer wall of the fixed plate. Thus, through the non-contact cooperation between the laser displacement sensor and the scale, the displacement of the baffle caused by the debris flow impact is accurately captured and the magnitude of the impact force is calculated. This effectively avoids the problem of contact sensors being easily damaged by strong impacts, and improves the reliability, accuracy, and stability of the monitoring data and the equipment.
[0017] 3. This invention activates an electric cylinder, whose output simultaneously drives a push rod to move linearly. After the push rod passes through a pre-set through hole, it contacts the arc-shaped plate and continuously applies pressure. Under the action of the pressure, the arc-shaped plate rotates smoothly around the axis of rotation at a certain angle. Impurities on its surface are evenly diffused to both sides under the thrust of the arc-shaped plate's rotation, effectively preventing impurities from accumulating and agglomerating on the surface of the arc-shaped plate and around the baffle, thus preventing impurities from hindering subsequent monitoring.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] See Figures 1 to 8 As shown, the present invention provides an impact-resistant debris flow impact force monitoring device, including a monitoring pile 1, and a fixing plate 3 is fixedly sleeved on the outer wall of the monitoring pile 1; The monitoring component includes a support rod 42 that is slidably disposed on both sides of the fixed plate 3. A baffle 41 is fixedly connected to one end of the support rod 42, and a laser displacement sensor 44 is installed at the other end through a connecting block 43. A scale 45 that cooperates with the laser displacement sensor 44 is fixedly connected to the fixed plate 3. It should be noted that, for reference Figures 1 to 3As shown, when a debris flow occurs, it directly impacts the surface of the baffle 41. Under the impact force of the debris flow, the baffle 41 is displaced backward. Since the baffle 41 is welded and fixed to the support rod 42, this displacement is synchronously transmitted to the support rod 42. The support rod 42 slides smoothly under the guidance of the guide sleeve, which in turn drives the connecting block 43, which is fixed to the support rod 42, to move synchronously. The laser displacement sensor 44 installed on the surface of the connecting block 43 also moves synchronously. At this time, the detection end of the laser displacement sensor 44 is always vertically aligned with the scale 45 on the outer wall of the fixed plate 3. Thus, through the non-contact cooperation between the laser displacement sensor 44 and the scale 45, the displacement of the baffle 41 caused by the debris flow impact is accurately captured and the magnitude of the impact force is calculated. This effectively avoids the problem of contact sensors being easily damaged by strong impacts, and improves the reliability, accuracy and stability of the monitoring data and the equipment.
[0022] The buffer mechanism includes an elastic buffer unit and a hydraulic buffer unit located between the fixed plate 3 and the baffle 41. The hydraulic buffer unit includes a hydraulic cylinder 56 hinged to the fixed plate 3 and a buffer rod B57 hinged to the baffle 41 and slidingly engaged with the hydraulic cylinder 56. One end of the buffer rod B57 located inside the hydraulic cylinder 56 is provided with a piston 58. A spring B510 is sleeved on the buffer rod B57. One end of the spring B510 abuts against a circular plate 59 fixed on the buffer rod A52. A pressure sensor 511 for detecting buffer pressure is provided between the hydraulic cylinder 56 and the circular plate 59. A solenoid valve 512 electrically connected to the pressure sensor 511 is provided on the piston 58 to adjust the buffer damping according to the magnitude of the impact force. It should be noted that, for reference Figures 1 to 4 As shown, during the backward movement of the baffle 41, the baffle 41 drives the buffer rod B57 to move into the hydraulic cylinder 56. The piston 58 at one end of the buffer rod B57 slides inside the hydraulic cylinder 56, compressing the medium inside the hydraulic cylinder 56. This, combined with the elastic buffering effect of the spring B510, forms a secondary hydraulic buffer. At the same time, the sleeve 51 slides relative to the buffer rod A52, and the spring A53 undergoes elastic deformation, forming a primary elastic buffer. The two-stage buffering structure works together to weaken the strong impact load of the debris flow and prevent equipment damage due to rigid impact. Meanwhile, during the buffering process, the pressure sensor 511 collects real-time data on the pressure difference between the hydraulic cylinder 56 and the circular plate 56. When the pressure signal between 9 reaches a preset threshold, the pressure sensor 511 and the solenoid valve 512 are electrically linked. The solenoid valve 512 automatically opens and adjusts the internal damping of the hydraulic cylinder 56 to achieve adaptive buffering. This ensures that the equipment can work stably under different intensity debris flow conditions. If the damping coefficient is fixed, it cannot adapt to debris flow impact forces of different intensities. When the impact force is too small, excessive damping can easily lead to buffer lag and failure to transmit the force to the displacement conversion module in time, affecting the real-time detection. When the impact force is too large, insufficient damping can not fully homogenize the impact force, still causing displacement fluctuations and affecting measurement accuracy.
[0023] The blowing mechanism is connected to the elastic buffer unit and is used to spray gas onto the laser displacement sensor 44 and the scale 45. The cleaning mechanism includes an arc-shaped plate 71 rotatably disposed on one side of the baffle 41, and a power component disposed on one side of the fixed plate 3. The power component is used to drive the baffle 41 to reset and drive the arc-shaped plate 71 to flip relative to the baffle 41.
[0024] In an optional embodiment, a photovoltaic panel 2 is fixedly installed on the outer wall of the monitoring pile 1. The photovoltaic panels 2 are symmetrically distributed on both sides of the monitoring pile 1, and the installation height of the photovoltaic panels 2 is higher than that of the fixed plate 3. The photovoltaic panels 2 receive sunlight and efficiently convert solar energy into electrical energy to provide continuous power for each module of the equipment.
[0025] In an optional embodiment, the elastic buffer unit includes multiple sets of sleeves 51 fixed to one side of the fixed plate 3. A buffer rod A52 fixed to the fixed plate 3 slides inside the sleeve 51. A spring A53 is provided inside the sleeve 51. One end of the spring A53 is fixedly connected to the inner wall of the sleeve 51, and the other end is fixedly connected to one end of the buffer rod A52.
[0026] In an optional embodiment, the blowing mechanism includes an air storage cylinder 61 connected to one side of the elastic buffer unit, two sets of symmetrically arranged nozzles 62 fixedly installed on one side of the connecting block 43, a connecting pipe 63 connecting the air storage cylinder 61 and the nozzles 62, a one-way suction valve installed at both ends of the air storage cylinder 61, and a one-way exhaust valve installed inside the connecting pipe 63.
[0027] In an optional embodiment, the nozzle of the connecting pipe 63 near the nozzle 62 is flat and faces the corresponding surfaces of the laser displacement sensor 44 and the scale 45.
[0028] It should be noted that, for reference Figure 3As shown, when the buffer mechanism is working, the sliding of the sleeve 51 will synchronously compress the gas inside the gas storage cylinder 61. During the gas compression process, the compressed gas can play an auxiliary buffering role on the sliding of the sleeve 51, further weakening the impact load of the debris flow. Subsequently, the compressed gas is transported to two sets of nozzles 62 through the connecting pipe 63 and the one-way exhaust valve. The flat nozzles of the two sets of nozzles 62 are precisely aimed at the laser displacement sensor 44 and the scale 45, continuously spraying compressed gas and forming a uniform protective gas film. This protective gas film can effectively block the dust and various attached impurities generated during the debris flow impact, preventing impurities from adhering to the emitting end of the laser displacement sensor 44 and the surface of the scale 45. At the same time, after the buffering is completed, the gas storage cylinder 61 draws in outside air through the one-way intake valve to complete the gas replenishment and storage, thereby ensuring the unobstructed monitoring optical path, eliminating measurement deviations caused by optical path obstruction or scattering, ensuring that the laser displacement sensor 44 can accurately capture displacement change signals, and ensuring the accuracy of measurement data.
[0029] In an optional embodiment, the power component includes an electric cylinder 8 mounted on one side of the fixed plate 3. A push rod 74 is fixedly connected to the output end of the electric cylinder 8. A through hole 75 is opened on the surface of the baffle 41. The push rod 74 is inserted into the through hole 75. A rotating shaft 72 is fixedly connected to the top end of the arc plate 71. A torsion spring 73 is fixedly connected between one end of the rotating shaft 72 and the top end of the baffle 41.
[0030] In an optional embodiment, two sets of arc-shaped plates 71 are symmetrically distributed on both sides of the baffle 41, and the bottom end of the arc-shaped plates 71 is flush with the bottom end of the baffle 41, which can fully cover the bottom and surrounding area of the baffle 41 and thoroughly clean the residual impurities in the gap at the bottom end of the baffle 41.
[0031] It should be noted that, for reference Figures 6 to 8 As shown, after the monitoring work is officially completed, the electric cylinder 8 is activated. The output end of the electric cylinder 8 synchronously drives the push rod 74 to move linearly. After the push rod 74 passes through the preset through hole 75, it contacts the arc plate 71 and continuously applies pressure. Under the action of the pressure, the arc plate 71 rotates smoothly around the axis of the rotating shaft 72 at a certain angle. The impurities on its surface are evenly diffused to both sides under the pushing force of the rotation of the arc plate 71, effectively preventing impurities from accumulating and agglomerating on the surface of the arc plate 71 and around the baffle 41, preventing impurities from hindering subsequent monitoring. At the same time, after the output end of the electric cylinder 8 pushes the push rod 74 to complete the impurity cleaning action, it synchronously contacts the baffle 41. With the driving force of the electric cylinder 8, the baffle 41 is driven to smoothly reset, ensuring that the baffle 41 accurately returns to the initial monitoring position.
[0032] In an optional embodiment, a guide sleeve is fitted on the outer wall of the support rod 42. The guide sleeve is fixedly connected to the fixing plate 3, and the inner wall of the guide sleeve is provided with a lubricating coating. The support rod 42 and the guide sleeve slide together, which can accurately limit the movement direction of the support rod 42, ensuring that the support rod 42 slides only along a preset straight line, avoiding the support rod 42 from deviating or tilting, thereby ensuring the smooth movement of components such as the baffle 41 and the buffer module connected to the support rod 42.
[0033] In an optional embodiment, the detection end of the laser displacement sensor 44 is vertically aligned with the scale surface of the scale 45, and the distance between the laser displacement sensor 44 and the scale 45 is 5 to 10 centimeters. The surface of the scale 45 is coated with an anti-reflective coating.
[0034] Working principle: The monitoring pile 1 is fixed in the gully of the debris flow area. When a debris flow occurs, the debris flow will directly impact the surface of the baffle 41. The baffle 41 will be displaced backward under the impact force of the debris flow. Since the baffle 41 is welded and fixed to the support rod 42, the displacement will be synchronously transmitted to the support rod 42. The support rod 42 will slide smoothly under the guidance of the guide sleeve, which will drive the connecting block 43 fixed to the support rod 42 to move synchronously. The laser displacement sensor 44 installed on the surface of the connecting block 43 will also move synchronously. At this time, the detection end of the laser displacement sensor 44 is always vertically aligned with the scale 45 on the outer wall of the fixed plate 3. Through the non-contact cooperation between the laser displacement sensor 44 and the scale 45, the displacement of the baffle 41 caused by the debris flow impact is accurately captured and the magnitude of the impact force is calculated. As the baffle 41 moves backward, it drives the buffer rod B57 to move into the hydraulic cylinder 56. The piston 58 at one end of the buffer rod B57 slides inside the hydraulic cylinder 56, compressing the medium inside the hydraulic cylinder 56. This, combined with the elastic buffering effect of the spring B510, forms a secondary hydraulic buffer. At the same time, the sleeve 51 slides relative to the buffer rod A52, and the spring A53 undergoes elastic deformation to form a primary elastic buffer. The two-stage buffering structure works together to weaken the strong impact load of the debris flow and prevent the equipment from being damaged by rigid impact. Meanwhile, during the buffering process, the pressure sensor 511 collects the pressure signal between the hydraulic cylinder 56 and the circular plate 59 in real time. When the pressure reaches the preset threshold, the pressure sensor 511 and the solenoid valve 512 are electrically linked. The solenoid valve 512 automatically opens and adjusts the internal damping of the hydraulic cylinder 56 to achieve adaptive buffering. When the buffer mechanism is working, the sliding of the sleeve 51 will synchronously compress the gas inside the gas storage cylinder 61. During the gas compression process, the compressed gas is then transported to two sets of nozzles 62 through the connecting pipe 63 and the one-way exhaust valve. The flat nozzles of the two sets of nozzles 62 are precisely aimed at the laser displacement sensor 44 and the scale 45, continuously spraying compressed gas and forming a uniform protective gas film. After the monitoring work is officially completed, start the electric cylinder 8. The output end of the electric cylinder 8 synchronously drives the push rod 74 to move linearly. After the push rod 74 passes through the preset through hole 75, it contacts the arc plate 71 and continuously applies extrusion pressure. Under the action of extrusion pressure, the arc plate 71 rotates smoothly around the axis of the rotating shaft 72 at a certain angle. The impurities on its surface are evenly diffused to both sides under the thrust of the rotation of the arc plate 71.
