Description

Technical Field

[0001] The invention relates to the technical field of bank slope measurement, in particular to a river bank slope measurement device for water conservancy monitoring. Background Art

[0002] In the field of water conservancy project safety monitoring, the stability of river bank slopes is directly related to flood control safety, ecological protection and the sustainable operation of infrastructure. In recent years, with the development of remote sensing mapping, three-dimensional laser scanning, drone oblique photography and Internet of Things sensor networks, bank slope monitoring has gradually evolved towards high precision, automation and real-time.

[0003] Therefore, the fusion analysis of multi-source heterogeneous data, the construction of long-term dynamic change models, and the control of measurement errors in complex environments are still technical difficulties. With the integration of emerging technologies such as the Internet of Things and AI algorithms, intelligent algorithms have become one of the core requirements for smart water conservancy construction.

[0004] When measuring river bank slopes and calculating bank slope data through remote sensing mapping, heavy rainfall, haze or extreme lighting conditions will significantly reduce the clarity of optical remote sensing images, resulting in the loss of texture features of drone oblique photography. Continuous rain or low temperature environments may also cause sensor signal attenuation or equipment stability degradation, resulting in data anomalies or missing data, thereby affecting the entire data collection and transmission. In traditional photogrammetry, dense bank slope vegetation will obscure the true shape of the surface, causing the surface features in traditional photogrammetry to be partially or completely obscured, which ultimately directly affects the reliability of bank stability assessment and landslide warning.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention uses a float and a fixed foundation pile. When the fixed foundation pile is placed on the bank slope and the float is in contact with the liquid surface of the river, the float performs initial baseline positioning of the entire fixed foundation pile. When the fixed foundation pile vertically sinks, the float is in an upward state relative to the fixed foundation pile, and the lever is driven to rotate to amplify the entire sinking distance. The magnification factor enables staff to more accurately control the entire sinking distance.

[0023] 2. During the entire measurement process, the float is located above the liquid surface and will be subject to the reciprocating rise and fall caused by the fluctuation of the liquid surface. This rise and fall will cause errors in the measured data. Through the reset spring set inside the movable rod and the pressure of the plug-in rod on one end of the reset spring, when the liquid surface fluctuates, the reset spring can offset this part of the lifting force, thereby reducing the error caused by the fluctuation of the river liquid surface;

[0024] 3. The circular disc and pendulum installed outside the protective shell can measure the inclination angle of the entire fixed foundation pile. The degree and rate of soil erosion on the slope are calculated by the placement time of the fixed foundation pile and the scale on the surface of the circular disc driven by the pendulum. The staff can then determine whether reinforcement is needed at that location based on the measured data to avoid subsequent landslides.

[0025] 4. When the pendulum rotates, the rotation angle can be transmitted through the first gear and the second gear, so that the unidirectional rotating teeth drive the matching rack to move. The displaced matching rack can adjust the position of the fulcrum, thereby changing the magnification ratio between the short arm and the long arm of the lever, and reducing the data measurement error caused by the tilt of the fixed foundation pile.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figures 1 to 8, which is the first embodiment of the present invention, provides a technical solution: a river bank slope measuring device for water conservancy monitoring, including a fixed foundation pile 1, a support plate 2 is provided on one side of the fixed foundation pile 1, the support plate 2 is L-shaped as a whole, the support plate 2 is used to support the measuring component, and provides stable support for the measuring component, while facilitating the staff to observe the displacement distance in real time, a protective shell 21 is provided on the side of the support plate 2 away from the fixed foundation pile 1, the protective shell 21 is used for protection, a buoyancy component 3 is provided on the end of the support plate 2 away from the fixed foundation pile 1, and the buoyancy component 3 and the fixed foundation pile 1 are on the same side of the support plate 2, and the buoyancy component 3 is used to When the device is installed at the junction of the bank slope and the river channel, when the fixed foundation pile 1 is inserted into the soil of the bank slope to provide stable support, the float 32 in the buoyancy component 3 can float above the river liquid surface based on its own buoyancy. The support plate 2 is provided with an amplification component 4 on the side away from the fixed foundation pile 1. The amplification component 4 is used to amplify the displacement measured by the buoyancy component 3. When the amplification component 4 causes the buoyancy component 3 to be relatively displaced relative to the settlement of the fixed foundation pile 1, the displacement distance will be amplified by the amplification component 4. Under the action of the amplification component 4, even a slight displacement of the fixed foundation pile 1 can be detected, thereby recording the data;

[0040] The buoyancy assembly 3 includes a movable rod 31 movably arranged at one end of the support plate 2 away from the fixed foundation pile 1, and the movable rod 31 has a cavity inside. The movable rod 31 is movably engaged with the support plate 2. When the float 32 floats on the liquid surface, the vertical sliding relationship formed between the movable rod 31 and the support plate 2 can prevent the float 32 from swinging due to liquid surface fluctuations, causing the displacement of the float 32 to deviate. Under the rotation of this deflection, the displacement baseline of the float 32 relative to the fixed foundation pile 1 deviates, affecting the recording of subsequent monitoring data. The movable rod 31 is provided with a float 32 at one end away from the support plate 2. The float 32 floats on the liquid surface. 2 is designed with a cavity inside. When the float 32 contacts the liquid surface, the cavity inside the float 32 makes it float above the liquid surface with buoyancy. Through the positioning of the float 32, the position of the fixed pile 1 is calibrated as a whole. After the fixed pile 1 is installed, when the fixed pile 1 sinks vertically, the float 32 rises as a whole relative to the fixed pile 1 under the action of its own buoyancy. The displacement difference between the two drives the amplification component 4 to work, amplifying the generated displacement difference, so that the staff can receive accurate data more intuitively, thereby judging the trend of the bank slope to sink vertically in the future and timely In order to protect and reinforce the bank slope, a positioning plate 33 is provided at one end of the movable rod 31 away from the float 32, and the positioning plate 33 is parallel to the longer section of the support plate 2 as a whole. A spherical hinge rod 34 is movably provided at one end of the positioning plate 33 away from the movable rod 31, and the spherical hinge rod 34 has a telescopic function. In the initial state, the inner rod of the spherical hinge rod 34 will extend a part to form a rotational connection with the lever 41. When the fixed pile 1 undergoes vertical displacement, the spherical hinge rod 34 will drive the lever 41 to rotate around the fulcrum 42. During the whole process, the telescopic function formed by the spherical hinge rod 34 will adjust the distance difference formed by the rotation of the lever 41. To compensate for this, the spherical hinge rod 34 is ensured to always drive the lever 41 to rotate around the fulcrum 42. The contact point between the spherical hinge rod 34 and the positioning plate 33 is a spherical hinge, and the other end of the spherical hinge rod 34 is rotatably connected to one end of the lever 41 on the amplification component 4. This allows the positioning plate 33 to rise synchronously when the float 32 is relatively displaced relative to the fixed pile 1. During the rising process of the positioning plate 33, the spherical hinge rod 34 is driven to pull the lever 41 to rotate. When the lever 41 rotates around the fulcrum 42, the horizontal displacement caused by the rotation of its two ends is amplified due to the setting of the position of the fulcrum 42.

[0041] The amplification component 4 includes a lever 41 movably arranged at one end of the spherical hinge rod 34 away from the positioning plate 33. The lever 41 is used to amplify the displacement ratio according to the position of the fulcrum 42 when the lever 41 as a whole rotates around the fulcrum 42. A movable groove 411 is provided on the side of the lever 41 close to the protective shell 21. The movable groove 411 is used to limit the fulcrum 42 as a whole, so that the fulcrum 42 as a whole can only be displaced along the movable groove 411, so that when the fixed foundation pile 1 tilts under the impact of the river, the position of the fulcrum 42 can be adjusted in time. The fulcrum 42 is movably provided on the lever 41, and the fulcrum 42 is engaged and slid with the movable groove 411. The initial position of the fulcrum 42 is one-sixth of the entire lever 41. Thus, the entire lever 41 is split into a short arm and a long arm, wherein the ratio of the two is one to five, so that the short arm rotatably connected to the spherical hinge rod 34 has its overall horizontal displacement magnified five times by the displacement distance of the long arm end when it rotates. The rotating secondary special-shaped connecting rod 43 on the protective shell 21 is a combination of a round rod and a square rod, and the round rod and the square rod are in a rotational connection relationship, wherein the position of the square rod forms an engaging and sliding engagement with the square groove opened on the protective shell 21, so that the rotating secondary special-shaped connecting rod 43 can slide and engage with the protective shell 21 through its overall square rod shape, while preventing the square rod segment from rotating synchronously when the round rod segment rotates. One end of the rotating secondary special-shaped connecting rod 43 is rotationally connected to the fulcrum 42;

[0042] The fixed pile 1 is installed on the bank slope close to the water flow, and the float 32 comes into contact with the river liquid surface to locate the position baseline. When the fixed pile 1 vertically sinks, the float 32 is in an overall upward state relative to the fixed pile 1, driving the spherical hinge rod 34 to drive the lever 41 to rotate. When the lever 41 rotates around the fulcrum 42, the displacement distance will be magnified proportionally, making the slight settlement distance easier to record.

[0043] The buoyancy assembly 3 also includes a triangular support 35 arranged on the side of the support plate 2 away from the float 32. The triangular support 35 is triangular in shape as a whole and is fixedly connected to the support plate 2 through three support rods. A plug-in rod 36 is provided on the side of the triangular support 35 close to the support plate 2, and the plug-in rod 36 forms a plug-in relationship with the movable rod 31. The plug-in rod 36 is used to limit the floating of the movable rod 31 and the float 32 as a whole to a certain extent through the reset spring 311 provided inside the movable rod 31, so as to prevent the float 32 from rising and falling when the liquid level fluctuates in the river, resulting in errors in the measurement data recording, which affects the subsequent In order to judge the trend of bank slope settlement, a reset spring 311 is movably provided inside the movable rod 31. The reset spring 311 is used to offset the up and down floating of the float 32 following the liquid surface when the float 32 is affected by the fluctuation of the liquid surface, thereby reducing the error caused by the fluctuation of the liquid surface affecting the measurement data. At the same time, the entire reset spring 311 can store the kinetic energy of the buoyancy generated by the float 32, so that the float 32 can release the stored kinetic energy within a certain range when the liquid surface drops, so as to make the float 32 continue to form contact with the liquid surface, thereby completing the re-baseline positioning of the float 32 on the fixed foundation pile 1.

[0044] The amplification component 4 also includes a locking rod 412 provided at the end of the lever 41 away from the spherical hinge rod 34. The locking rod 412 is used to form a locking and sliding movement with the linear guide rail 44. When the lever 41 rotates, the entire body will swing around the fulcrum 42. The swing curve is a circular curve of the entire lever 41. Through the locking action between the linear guide rail 44 and the locking rod 412 on the lever 41, when the lever 41 rotates around the fulcrum 42, the linear guide rail 44 will be driven to move horizontally, and the movement of the entire linear guide rail 44 will not affect the rotation of the lever 41. The locking rod 412 is movably provided with a linear guide rail 44 at one end away from the lever 41, and the linear guide rail 44 and the locking rod 412 are locked and slid, and the linear guide rail 44 is close to One side of the engaging rod 412 has a linear notch, through which the engaging rod 412 on the lever 41 will not interfere with the swinging when the lever 41 swings. A conveying rack 45 is provided on the side of the linear guide 44 away from the engaging rod 412, and the conveying rack 45 and the linear guide 44 are arranged vertically. The conveying rack 45 is used to transmit the horizontal displacement formed by the lever 41, thereby driving the meshing gear set 46 engaged on one side of the conveying rack 45 to rotate. The rotation of the meshing gear set 46 will synchronously drive another positioning scale 47 to rotate. Through the rotation of the positioning scale 47, the displacement distance conveyed by the conveying rack 45 is synchronously transmitted. The conveying rack 45 is meshed with a meshing gear set 46 on the side away from the linear guide 44. The meshing gear set 46 is composed of two matching gears and a one-way ratchet. At the same time, the meshing gear set 46 has the same module as the conveying rack 45. Under the action of the consistent module of the meshing gear set 46 and the conveying rack 45, the overall displacement of the conveying rack 45 can be synchronously transmitted to the meshing gear set 46, thereby converting the horizontal displacement into a rotation angle. A one-way ratchet is provided inside the matching gear meshing with the conveying rack 45. Through the one-way transmission action of the one-way ratchet, another matching gear on the meshing gear set 46 is driven, thereby causing the other matching gear to drive the positioning scale 47, causing the positioning scale 47 to rotate. When the conveying rack 45 is reset as a whole under the action of the lever 41, only the positioning scale 47 is rotated. The mating gear of the dynamically arranged one-way ratchet rotates, and the reset rotation will not be transmitted to the positioning scale 47, which can avoid the reset displacement of the conveying rack 45 from being transmitted, affecting the recording of the measurement data. The meshing gear set 46 is meshed with a positioning scale 47 on the side away from the conveying rack 45. The surface of the positioning scale 47 is engraved with a scale for recording the displacement distance of the conveying rack 45. The positioning scale 47 is also tooth-shaped on the side close to the meshing gear set 46, and the module is consistent with that of the meshing gear set 46. When the mating gear on the meshing gear set 46 that meshes with the positioning scale 47 rotates, the movement distance of the conveying rack 45 can be directly recorded, and the distance after movement can be pointed by the cooperation of the positioning scale 47 and the positioning pointer 23.It allows staff to read the vertical settlement value very conveniently.

[0045] A special-shaped placement bin 22 is provided on the side of the protective shell 21 away from the support plate 2, and a chamber is provided inside the special-shaped placement bin 22. The chamber provided in the special-shaped placement bin 22 is used to facilitate the support of the conveying rack 45, the meshing gear set 46 and the positioning scale 47. At the same time, the limit assembly 5 provided inside the chamber can limit the overall movement of the positioning scale 47, so that one side of the positioning scale 47 is always meshed with the meshing gear set 46. A limit assembly 5 is provided inside the special-shaped placement bin 22. The limit assembly 5 is used to limit the positioning scale 47 to a certain extent, so that the positioning scale 47 can always form a meshing relationship with the mating gear on the meshing gear set 46 that does not have a one-way ratchet. A positioning pointer 23 is provided on one side of the special-shaped placement bin 22, and the initial position of the positioning pointer 23 is located on the zero scale on the surface of the positioning scale 47. Under the action of the positioning pointer 23, the staff can finally read the final value intuitively.

[0046] During use, the device is inserted into the junction of the bank slope and the river channel, so that the fixed pile 1 is vertically fixed on the bank slope. At the same time, the float 32 is placed above the liquid surface of the river channel and contacts the liquid surface. The float 32 floats on the liquid surface to form an initial reference line. When the fixed pile 1 as a whole vertically sinks, the float 32 is in an upward state relative to the fixed pile 1, so that the float 32 drives the spherical hinge rod 34 to move synchronously. Under the displacement of the spherical hinge rod 34, the lever 41 is driven to rotate around the fulcrum 42. When the lever 41 Under the rotation, the long arm section of the lever 41 amplifies the entire displacement five times, and the amplified displacement will be transmitted horizontally through the provided conveying rack 45, and then transmitted through the provided meshing gear set 46, so that the positioning ruler 47 meshed on the other side of the meshing gear set 46 moves, and the positioning pointer 23 on the special-shaped placement bin 22 points to the scale on the positioning ruler 47, so as to obtain the final reading, which is reduced by five times, and is the vertical settlement distance of the entire slope at the position of the fixed foundation pile 1.

[0047] Example 2

[0048] See also Figures 1 to 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that:

[0049] The limiting assembly 5 includes a support column 51 arranged inside the special-shaped placement bin 22, and a top support plate 52 is provided at one end of the support column 51 close to the meshing gear set 46, and an elastic sheet 53 is symmetrically provided on the side of the top support plate 52 away from the support column 51, and a limiting plate 54 is provided at one end of the elastic sheet 53 close to the meshing gear set 46, and a rubber gasket is provided on the side of the limiting plate 54 close to the positioning scale 47. The positioning scale 47 is limited by the rubber gasket provided on the limiting plate 54, so that when the positioning scale 47 moves, it will always form a meshing relationship with the meshing gear set 46 to avoid the occurrence of loose meshing.

[0050] A tilt measuring assembly 6 is provided on one side of the protective shell 21 close to the fixed pile 1 . Anchor pins 11 are arranged in an array on the surface of the fixed pile 1 , and the anchor pins 11 are tilted upward.

[0051] The tilt measurement assembly 6 includes a circular disc 61 arranged on one side of the protective shell 21, and an annular positioning plate 62 is provided on the circular disc 61. A transmission shaft 63 is movably provided inside the annular positioning plate 62, and one end of the transmission shaft 63 passes through the protective shell 21. A tilt pointer 64 is provided on the side of the transmission shaft 63 close to the circular disc 61, and the tilt pointer 64 is aligned with the zero scale on the surface of the circular disc 61.

[0052] During use, when the fixed pile 1 tilts, the pendulum 631 arranged on the surface of the protective shell 21 will rotate relative to the circular disc 61 based on the principle that it is always vertical to the center of the earth. During the rotation, the rotation angle is transmitted under the action of the first gear 65 and the second gear 66, thereby driving the entire rotating rod 67 to rotate synchronously. Under the rotation of the rotating rod 67, one of the unidirectional rotating teeth 68 is driven to rotate. Under the rotation of the unidirectional rotating tooth 68, the matching rack 69 is driven to move. The displaced matching rack 69 will change the current position of the fulcrum 42, thereby correcting the amplification ratio of the lever 41, reducing the influence of the overall tilt of the fixed pile 1 on the entire vertical settlement measurement data.

[0053] The remaining structures are the same as those of Example 1.

[0055] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0056] The tilt measuring assembly 6 also includes a first gear 65 arranged at the end of the transmission shaft 63 away from the tilt pointer 64, and a second gear 66 is meshed with one side of the first gear 65. A rotating rod 67 is provided through the second gear 66, and the rotating rod 67 is rotatably connected to the protective shell 21, and a one-way rotating tooth 68 is provided at the end of the rotating rod 67 away from the second gear 66. There are two one-way rotating teeth 68, and a one-way ratchet is provided inside the rotating rod 67, and the rotation direction of the one-way ratchet is opposite, so that the rotating rod 67 can drive the corresponding one-way rotating tooth 68 to rotate regardless of whether it rotates forward or reverse. The rotation of the one-way rotating tooth 68 moves the mating rack 69, so that the position of the fulcrum 42 on one side is adjusted under the action of the rotating pair special-shaped connecting rod 43 provided on the mating rack 69, thereby avoiding errors in measurement data caused by tilting of the device.

[0057] A mating rack 69 is provided on the one-way rotating tooth 68 near the side of the rotating secondary special-shaped connecting rod 43, and the mating rack 69 is fixedly connected to the rotating secondary special-shaped connecting rod 43. A pendulum 631 is provided on the transmission shaft 63, and the pendulum 631 is fixedly connected to the transmission shaft 63 through a support rod. The pendulum 631 has a conical outer contour so that when the device is tilted, the pendulum 631 will rotate relative to the device itself, and the entire transmission shaft 63 is driven to rotate during the rotation, thereby causing the transmission shaft 63 to rotate. Under the action of the transmission shaft 63, the second gear 66 is driven to rotate synchronously. The maximum diameters of the first gear 65 and the second gear 66 are different, so that when the first gear 65 rotates, the second gear 66 will transmit the rotation angle to cause the fulcrum 42 to start to move, thereby adjusting the entire magnification ratio.

[0058] A limiting groove 24 is formed through one side of the protective shell 21 . An L-shaped clamping plate 451 is provided on the side of the conveying rack 45 close to the protective shell 21 . The L-shaped clamping plate 451 is engaged and slidably engaged with the limiting groove 24 .

[0059] At the same time, in this process, as the river continuously washes away the soil at the edge of the bank slope, the fixed foundation pile 1 set here will be in a tilted state. This tilted state will affect the recording of the entire vertical settlement data. When the entire tilt angle is transmitted through the tilt measurement component 6, the position of the set fulcrum 42 is adjusted to reduce the data error caused by the tilt angle, so that the measured vertical settlement distance is closer to the actual data. The set tilt measurement component 6 will drive the pendulum 631 to tilt relative to the fixed foundation pile 1 according to the principle that the pendulum 631 is suspended at the center of the earth. For example, when the overall length of the pendulum 631 connected to the fixed foundation pile 1 is 20 mm and the mass is 0.5 kg, when the tilt angle of the fixed foundation pile 1 is 3°, the horizontal displacement of the pendulum 631 and the fixed foundation pile 1 is calculated according to the formula , it can be known from the conversion that the final displacement distance is 20×sin3°≈1.05mm, and then the angular rotation of this part is transmitted to the conveying rack 45 through the cooperation of the first gear 65 and the second gear 66 on one side of the transmission shaft 63, so that the displacement of the conveying rack 45 meets 1.05 mm, forming a new lever transmission ratio, specifically, the long arm section is 51.05mm, and the short arm section is 8.95mm. The new transmission ratio ≈5.7 is obtained by calculation, thereby compensating the vertical settlement data, so that when the device tilts, the settlement error caused by the tilt is reduced. Under the action of the tilt pointer 64 and the circular dial 61, the entire tilt angle can be displayed more intuitively, and auxiliary calculations are performed so that the results can be verified twice to confirm the final data. It can also record the degree of soil erosion of the entire slope at this location, and infer whether reinforcement is needed here in the future to avoid landslides caused by river erosion.
