Description

Technical Field

[0001] This application belongs to the technical field of landslide geological hazard monitoring, and in particular relates to a monitoring device and method for the transfer of underwater deformation characteristics of landslides. Background Technology

[0002] The underwater deformation characteristics of landslides in reservoirs, riverbanks, and coastlines are important factors in analyzing landslide deformation. Under the influence of water erosion, the internal structure of underwater landslides gradually loosens and deforms. If corresponding protective measures are not taken before the underwater landslide deforms to a certain extent, it may lead to the collapse of the underwater landslide, raising the riverbed water level and causing floods. Therefore, there is a need for equipment or devices that can monitor the underwater deformation characteristics of landslides in order to know the degree of underwater landslide deformation in a timely manner.

[0003] In the existing technology, there is a device that can monitor the underwater deformation characteristics of landslides. It mainly consists of a buoy, a positioning unit, an anchor, and a guy wire device. The anchor deforms in tandem with the underwater landslide, and the deformation degree of the underwater landslide is indirectly measured by the length and attitude of the guy wire device. This structure has poor waterproofing capabilities, and the internal mechanism or circuit of the guy wire device is easily damaged by prolonged immersion in water, making it difficult to achieve long-term monitoring of the deformation characteristics of underwater landslides. Summary of the Invention

[0004] This application provides a device and method for monitoring the transfer of underwater deformation characteristics of landslides, which is used to achieve long-term monitoring of underwater landslide deformation characteristics.

[0005] The first objective of this invention is achieved by the following technical solution:

[0006] A landslide underwater deformation characteristic transfer monitoring device includes:

[0007] Floaters, which float on the water surface;

[0008] The monitoring body is fixedly connected to the top of the float. The monitoring body has a built-in energy storage unit, a main control unit, and multiple monitoring units. The energy storage unit is electrically connected to the main control unit and the monitoring units to supply power to the main control unit and the monitoring units. The monitoring units are used to monitor the shear stress of the underwater slope. The monitoring units are electrically connected to the main control unit to send the acquired shear stress information to the main control unit.

[0009] Multiple elastic rods are inserted into an underwater slope, and the elastic rods deform in conjunction with the underwater slope. The head of each elastic rod is connected to a cable, and the telescopic end of the monitoring unit is connected to the elastic rod through the cable, which is always under tension.

[0010] Multiple anchor heads are anchored to the riverbed, and multiple connecting ropes are fixedly connected to the bottom side of the float, which is connected to the anchor head through the connecting ropes.

[0011] An antenna is electrically connected to the main control unit to forward the output information of the main control unit.

[0012] Through the above technical solution, the monitoring body is fixedly connected to the top side of the float, allowing it to float on the water surface without direct contact with the water, thus reducing the possibility of submersion. The main control unit built into the monitoring body is an information processing and storage unit. The energy storage unit is used to store electrical energy and power the main control unit and multiple monitoring units. Multiple monitoring units are electrically connected to the main control unit to send the detected underwater slope shear stress information to the main control unit for processing. When the underwater slope deforms, it provides lateral shear stress to the elastic rod, causing the elastic rod to deform and the tensioned cable to provide stress to the monitoring units. The monitoring unit transmits the corresponding shear stress, enabling it to monitor the underwater deformation characteristics of the underwater landslide. Multiple anchors are anchored to the riverbed, and each anchor is connected to a buoy via a connecting rope, reducing the possibility of the buoy shifting or overturning due to wind or waves. The antenna is electrically connected to the main control unit to relay its output information, thus expanding the propagation range of the output information. Compared to existing technologies, the monitoring unit of this application is less likely to come into direct contact with water, exhibiting better waterproofing. Furthermore, the monitoring unit acquires shear stress information of the underwater landslide through an elastic long rod, thereby achieving long-term monitoring of the underwater landslide deformation characteristics.

[0013] This application further specifies that: the monitoring unit is an electronic spring force gauge, the telescopic end of the monitoring unit is disposed away from the float, a fixed pulley is disposed on the top side of the monitoring body, and the cable is wound around the fixed pulley; the cable includes a first rope segment and a second rope segment, the first rope segment is vertically disposed and fixedly connected to the monitoring unit, and the second rope segment is parallel to the corresponding elastic rod and fixedly connected to the elastic rod.

[0014] Through the above technical solution, the monitoring unit uses an electronic spring force gauge, which has high sensitivity; the telescopic end of the monitoring unit is set away from the float to improve waterproofing and reduce the possibility of water immersion; a fixed pulley is set on the top side of the monitoring unit, and the cable is wound around the top pulley. The fixed pulley is used to change the direction of force during the transmission of landslide shear stress, and can also reduce the possibility of the accuracy of the measured landslide shear stress information being affected by the friction of the cable with the outer shell of the monitoring body; the first rope segment of the cable is set vertically and fixedly connected to the monitoring unit, so that the direction of the cable providing landslide shear stress is vertical, so that the monitoring unit composed of the electronic spring force gauge can perform data monitoring; the second rope segment is set parallel to the elastic rod and fixedly connected to the elastic rod, so that when the elastic rod deforms, the landslide shear stress can be transmitted to the monitoring unit through the cable more accurately.

[0015] This application further specifies that: the monitoring subject has a built-in positioning unit, which is used to transmit positioning information; the positioning unit is electrically connected to the antenna to expand the propagation range of the positioning information through the antenna.

[0016] Through the above technical solution, the positioning unit in the monitoring unit is used to transmit positioning information so that the staff can clearly know the specific location of the device in this application; the positioning unit is electrically connected to the antenna to expand the propagation range of the positioning information and improve the stability of the positioning information propagation.

[0017] This application further specifies that: a solar panel is provided on the top side of the monitoring subject, the solar panel is ring-shaped, and the solar panel is electrically connected to the energy storage unit and the positioning unit to charge the energy storage unit and the positioning unit.

[0018] Through the above technical solution, a ring-shaped solar panel is installed on the top side of the monitoring unit, which can make the top side of the monitoring unit uniformly stressed and less prone to tipping over; the solar panel is electrically connected to the energy storage unit and the positioning unit so as to charge the energy storage unit and the positioning unit when receiving sunlight, thereby enabling the device of this application to perform long-term monitoring.

[0019] This application further specifies that: the envelope of the float is a cylinder, and the plurality of anchor heads are uniformly arranged along the outer periphery of the float; the envelope of the monitoring body is a cylinder, and the monitoring body is concentric with the float.

[0020] With the above technical solution, the envelope of both the float and the monitoring body is a cylinder, and the monitoring body and the float are concentric, which helps to distribute the force on the float evenly and makes it less likely to overturn; multiple anchor heads are evenly arranged along the outer periphery of the float to further reduce the possibility of the float overturning.

[0021] The second objective of this invention is achieved by the following technical solution:

[0022] A method for monitoring the transfer of underwater deformation characteristics of landslides, applied to the aforementioned underwater deformation characteristic transfer monitoring equipment for landslides, the method comprising:

[0023] Based on multiple shear stress information and screening threshold ranges, the shear stress information within the screening threshold range is retained as monitoring information;

[0024] Calculate the mean of several monitoring information items and use it as output information;

[0025] The output power of the main control unit is adjusted based on the location information and the preset station receiving coordinates.

[0026] Based on the output power, the output information is sent to the antenna.

[0027] The above technical solution first selects shear stress information within the selection threshold range as monitoring information, then calculates the average of several monitoring information as output information, adjusts the output power of the main control unit according to the positioning information and the preset station receiving coordinates, and finally sends the output information to the antenna at the adjusted output power. Compared with the prior art, the monitoring method of this application can automatically adjust the output power of the main control unit according to the positioning information to adjust the transmission range of the output information, so that the information receiving terminal can continuously acquire the output information, thereby realizing continuous monitoring of underwater landslide deformation characteristics.

[0028] This application further specifies that, after retaining the shear stress information within the screening threshold range as monitoring information based on multiple shear stress information and a screening threshold range, the method also includes:

[0029] If all shear stress information exceeds the screening threshold range, an alarm message will be sent.

[0030] With the above technical solution, when all shear stress information exceeds the screening threshold range, it indicates that the connection between each monitoring unit and its corresponding elastic rod is abnormal, such as the cable breaking or loosening, causing the value of the shear stress information monitored by the monitoring unit to be lower than 0. At this time, an alarm message is issued to the staff so that the connection between each monitoring unit and its corresponding elastic rod can be repaired in time, which is conducive to long-term monitoring of underwater landslide deformation characteristics.

[0031] This application further specifies that: adjusting the output power of the main control unit based on positioning information and preset station receiving coordinates includes:

[0032] Based on location information and preset station receiving coordinates, calculate the information transmission distance;

[0033] Calculate the current maximum propagation distance based on the current output power;

[0034] If the current maximum propagation distance is lower than the information transmission distance, increase the output power.

[0035] The above technical solution calculates the information transmission distance between the positioning information and the pre-set station receiving coordinates based on the positioning information and the station receiving coordinates. Then, it calculates the current maximum propagation distance based on the current output power. If the current maximum propagation distance is lower than the information transmission distance, the output power is increased to increase the maximum propagation distance, so that the information receiving station can receive stable output information, which is beneficial for long-term monitoring of underwater landslide deformation characteristics.

[0036] This application is further configured such that, after sending the output information to the antenna based on the output power, the method includes:

[0037] Obtain energy storage information and charging power;

[0038] Based on the output power, the energy storage information, and the charging power, the output mode of the output information is adjusted.

[0039] The above technical solution adjusts the output mode of the output information based on the output power, energy storage information, and charging power to achieve energy saving, thereby facilitating long-term monitoring of underwater landslide deformation characteristics.

[0040] This application further specifies that: adjusting the output mode of the output information based on the output power, the energy storage information, and the charging power includes:

[0041] If the energy storage information is lower than a preset energy storage threshold and the charging power is lower than the output power, the output mode of the output information is switched to a periodic output mode.

[0042] With the above technical solution, when the energy storage information is lower than the preset energy storage threshold and the charging power is lower than the output power, the energy storage unit is insufficient to support the main control unit to continuously send out output information. The output mode of the output information is switched to the periodic output mode to send out output information at intervals, thereby reducing the possibility that the main control unit will not be able to work properly due to the depletion of the energy storage unit's power.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. Compared with the prior art, the monitoring unit of this application is difficult to come into direct contact with water, has a better waterproof effect, and the monitoring unit obtains the underwater deformation characteristics of the underwater landslide through the elastic long rod, thereby realizing long-term monitoring of the deformation characteristics of the underwater landslide.

[0045] 2. Compared with existing technologies, the first rope segment of the cable is vertically set and fixedly connected to the monitoring unit, so that the direction of the cable providing landslide shear stress is vertical, so as to facilitate data monitoring by the monitoring unit composed of electronic spring force gauges; the second rope segment is set parallel to the elastic rod and fixedly connected to the elastic rod, so that when the elastic rod deforms, the landslide shear stress can be more accurately transmitted to the monitoring unit through the cable.

[0046] 3. Compared with the prior art, the monitoring method of this application can automatically adjust the output power of the main control unit according to the positioning information to adjust the information transmission range of the output information, so that the information receiving terminal can continuously acquire the output information, thereby realizing continuous monitoring of the deformation characteristics of underwater landslides.

Detailed Implementation

[0054] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] It should be noted that when the shear stress of the underwater slope 100 exceeds the shear strength of the landslide soil, the underwater slope 100 will deform or collapse.

[0056] This application provides a device and method for monitoring the transfer of underwater deformation characteristics of landslides, which is used to achieve long-term monitoring of the deformation characteristics of underwater landslides.

[0057] Example 1

[0058] like Figure 1 and Figure 2 As shown, the underwater deformation characteristic transfer monitoring device for landslides according to this application includes a float 1, a monitoring body 2, an antenna 5, two elastic rods 3, three anchor heads 4, and two cables 6. The monitoring body 2 is fixedly connected to the top of the float 1, so that the monitoring body 2 can float on the water surface and not come into direct contact with the water, reducing the possibility of the monitoring body 2 being submerged. The monitoring body 2 is equipped with an energy storage unit 21, a main control unit 22, and two monitoring units 23. The energy storage unit 21 is electrically connected to the main control unit 22 and the two monitoring units 23 to supply power to the main control unit 22 and the monitoring units 23. The telescopic end of the monitoring unit 23 is set away from the float 1 to reduce the possibility of the monitoring unit 23 being submerged in water and improve the waterproof effect. One end of the cable 6 is fixedly connected to the telescopic end of the monitoring unit 23, and the other end is fixedly connected to the elastic rod 3. The rod body of the elastic rod 3 is inserted into the underwater landslide 100. The cable 6 is always kept taut. When the underwater landslide 100 occurs... During deformation, lateral shear stress is provided to the elastic rod 3, causing the elastic rod 3 to deform. This causes the tensioned cable 6 to transmit the corresponding shear stress to the monitoring unit 23, enabling the monitoring unit 23 to monitor the underwater deformation characteristics of the underwater slope 100. The monitoring unit 23 is electrically connected to the main control unit 22 to send the acquired shear stress information to the main control unit 22. The antenna 5 is electrically connected to the main control unit 22 to forward the shear stress information and expand the information propagation range, allowing staff to receive clearer information. The anchor head 4 is anchored to the riverbed 200, and the bottom of the float 1 is fixedly connected to three connecting ropes 41. The anchor head 4 is connected to the float 1 through the connecting ropes 41. Compared with the prior art, the monitoring unit 23 of this application is less likely to come into direct contact with water, has a better waterproof effect, and the monitoring unit 23 obtains the underwater deformation characteristics of the underwater slope 100 through the elastic rod 3, thereby realizing long-term monitoring of the deformation characteristics of the underwater slope 100.

[0059] In this embodiment, the float 1 is composed of a foam sponge 11 and a shell 12; the connecting rope 41 is connected to the float 1 by punching holes in the shell 12; a layer of waterproof adhesive is coated between the foam sponge 11 and the monitoring body 2 to improve the waterproof effect.

[0060] In this embodiment, the elastic rod 3 is made of carbon fiber, which is lightweight, making it less likely for the float 1 to tip over, and has good elastic properties.

[0061] Preferably, a layer of waterproof adhesive is brushed onto the top side of the monitoring body 2 to further improve the waterproof effect.

[0062] Reference Figure 2 The monitoring unit 2 also has a built-in positioning unit 24 and a solar panel 25. In this embodiment, the positioning unit 24 is a GPS locator with a built-in independent power supply. The positioning unit 24 is used to send positioning information to staff or information receiving stations so that staff can know the specific location of the device in a timely manner. The positioning unit 24 is electrically connected to the antenna 5 to improve the propagation range of the positioning information and improve the stability of the positioning information propagation. The solar panel 25 is ring-shaped and set on the top side of the detection unit, so that the top of the monitoring unit 23 is evenly stressed, reducing the possibility of the monitoring unit 23 tipping over. The solar panel is electrically connected to the energy storage unit 21 and the positioning unit 24 to convert the received solar energy into solar energy and provide charging for the energy storage unit 21 and the positioning unit 24, thereby improving the battery life of the device and enabling the device to monitor the deformation characteristics of the underwater slope 100 for a long time.

[0063] Reference Figure 2 Both the float 1 and the monitoring body are cylindrical, and the monitoring body and the float 1 are concentric, so that the force on the top side of the float 1 is uniform, reducing the possibility of the equipment of this application tipping over.

[0064] Reference Figure 1 and Figure 3 Three anchor heads 4 are evenly arranged along the outer periphery of the bottom of the float 1 so that the bottom of the float 1 is subjected to uniform force, and when the float 1 is about to overturn, the corresponding anchor head 4 can pull the float 1 to limit its overturning.

[0065] Reference Figure 3The monitoring unit 23 uses an electronic spring force gauge, which has high sensitivity and is effective in measuring the shear stress of the underwater slope 100. A pulley frame 71 is welded to the top side of the monitoring body 2, and a fixed pulley 7 is rotatably connected to the pulley frame 71. The pulley frame 71 is used to support the fixed pulley 7, and the fixed pulley 7 is used to change the direction of force during the transmission of landslide shear stress. The cable 6 is wound around the fixed pulley 7 and includes a first rope segment 61 and a second rope segment 62. The first rope segment 61 is vertically set and fixedly connected to the monitoring unit 23, so that the direction of the shear stress provided by the cable 6 to the landslide is vertical, thereby enabling the monitoring unit 23, which is composed of an electronic spring force gauge, to obtain more accurate shear stress information. The second rope segment 62 is set parallel to the corresponding elastic rod 3 and fixedly connected to the elastic rod 3, so that the second rope segment 62 always remains taut when the elastic rod 3 deforms, thereby more accurately transmitting the shear stress of the underwater slope 100 to the unit through the cable 6.

[0066] Preferably, the cable 6 is made of steel strands, which has good structural strength and is not easy to break.

[0067] The installation steps for the device in this application are as follows:

[0068] Place the float 1 on the water surface near the underwater slope 100, and drive the elastic rod 3 into the soil of the underwater slope 100 to pre-fix the elastic rod 3; put the three anchor heads 4 into the riverbed 200 to prevent the float 1 from overturning or shifting relative to the underwater slope 100; then insert the elastic rod 3 further into the soil of the underwater slope 100 to keep the cable 6 taut; finally, zero the detection value of the monitoring unit 23 and receive shear stress information through the information receiving station or mobile terminal.

[0069] Example 2

[0070] Reference Figure 4 Based on Embodiment 1, this application discloses a method for monitoring the transfer of underwater deformation characteristics of landslides, applied to the aforementioned underwater deformation characteristic transfer monitoring device. The main control unit has a built-in memory and processor to implement the steps of the underwater deformation characteristic transfer monitoring method. The underwater deformation characteristic transfer monitoring method of this application includes:

[0071] S10: Based on multiple shear stress information and screening threshold ranges, retain the shear stress information within the screening threshold range as monitoring information.

[0072] In this embodiment, two shear stress information parameters are set; the screening threshold range is 0kN-5kN; the maximum value of the screening threshold range needs to be considered in conjunction with the depth of the elastic rod inserted into the underwater slope. In other embodiments, it can be adjusted according to the actual situation; the depth of the elastic rod inserted into the underwater slope should be appropriate to maintain the shear stress information within the screening threshold range; the monitoring unit needs to be zeroed after the elastic rod is inserted.

[0073] Specifically, shear stress information within the screening threshold range is selected as monitoring information.

[0074] After step S10, the method further includes:

[0075] If all shear stress information exceeds the screening threshold range, an alarm message will be sent.

[0076] Specifically, when all shear stress information is below 0kN, it indicates that all cables 6 are broken or slack. The main control unit 22 sends maintenance information to the information receiving station through the antenna 5, enabling staff to promptly inspect the connections of each monitoring unit 23 and the corresponding elastic rod 3, thus facilitating long-term monitoring of the deformation characteristics of the underwater landslide. When all shear stress information is above 5kN, it indicates that the shear force of the underwater landslide is too large and a collapse is imminent. Corresponding protective measures need to be taken in a timely manner to reduce the possibility of the underwater landslide collapse.

[0077] S20: Calculate the mean of several monitoring data points and use it as output information.

[0078] In this embodiment, the monitoring information can be one or two.

[0079] Specifically, the main control unit calculates the average of several monitoring data points as the output information.

[0080] S30: Adjust the output power of the main control unit based on the positioning information and the preset station receiving coordinates.

[0081] In this embodiment, the station receives coordinates that are preset within the positioning unit (i.e., the GPS locator).

[0082] Specifically, the output power of the main control unit is adjusted based on the positioning information of the positioning unit and the preset station receiving coordinates, thereby adjusting the propagation range of the output information.

[0083] Reference Figure 5 Step S30 includes:

[0084] S31: Calculate the information transmission distance based on the location information and the preset station receiving coordinates;

[0085] S32: Calculate the current maximum propagation distance based on the current output power;

[0086] S33: If the current maximum propagation distance is lower than the information transmission distance, increase the output power.

[0087] In this embodiment, the shortest distance between the coordinates of the positioning information and the preset station receiving coordinates is calculated as the information transmission distance based on the positioning information and the preset station receiving coordinates; the main control unit calculates the ideal transmission distance under the current output power as the current maximum propagation distance based on the output band, frequency and current output power.

[0088] Specifically, based on the positioning information and the pre-set station receiving coordinates, the shortest distance between the positioning information coordinates and the station receiving coordinates is calculated. The main control unit then calculates the current maximum propagation distance based on the current output power. If the current maximum propagation distance is lower than the information transmission distance, the output power is increased to increase the maximum propagation distance, so that the information receiving station can receive stable output information, which is conducive to long-term monitoring of underwater landslide deformation characteristics.

[0089] S40: Based on the output power, send the output information to the antenna.

[0090] Specifically, the output information is sent to the antenna based on the adjusted output power. Compared with the prior art, the method of this application can automatically adjust the output power of the output information according to the positioning information so that the information receiving station can receive stable output information, thereby realizing continuous monitoring of underwater landslide deformation characteristics.

[0091] After step S40, the method of this application further includes:

[0092] Obtain energy storage information and charging power;

[0093] The output mode is adjusted based on the output power, energy storage information, and charging power.

[0094] Specifically, based on the output power of the main control unit, the energy storage information of the energy storage unit, and the charging power of the solar panel, the main control unit adjusts the output mode of the output information to save power and reduce the situation where the equipment of this application cannot continue to work due to insufficient power, so as to facilitate long-term monitoring of underwater landslide deformation characteristics.

[0095] The output modes that adjust the output information based on output power, energy storage information, and charging power include:

[0096] If the energy storage information is lower than the preset energy storage threshold and the charging power is lower than the output power, the output mode of the output information will be switched to the periodic output mode.

[0097] In this embodiment, the periodic output mode refers to sending output information at intervals. The interval time of the output information is set according to the actual situation. The lower the energy storage, the longer the interval time. The energy storage threshold is 20% of the energy storage capacity of the energy storage unit.

[0098] Specifically, when the energy storage capacity of the energy storage unit is less than 20% and the charging power of the solar panel is lower than the output power of the main control unit, the output mode of the output information is switched to the periodic output mode to send the output information to the information receiving station at intervals, thereby reducing the power consumption rate and reducing the possibility that the main control unit will not work properly due to the depletion of the energy storage unit's power. This enables the device of this application to monitor the deformation characteristics of underwater landslides for a long time.

[0099] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in each of the foregoing embodiments, or equivalent substitutions can be made to some of the features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of this application, and should all be included within the protection scope of this application.
