Abstract
Description
Technical Field
[0001] This invention relates to the field of seepage prevention construction, and more specifically to a geotextile roll laying control system. Background Technology
[0002] For ease of storage and transportation, geosynthetic materials are mostly sold in roll form, such as geomembranes, geotextiles, and waterproof blankets. When used, the geosynthetic rolls are laid out. When the rolls are heavy, the difficulty of horizontal and vertical laying increases significantly. For example, each roll of HDPE geomembrane and GCL waterproof blanket can weigh over 1 ton, requiring auxiliary tools to hoist it before laying. As the weight of the geosynthetic roll increases, the laying difficulty also increases. Furthermore, in practical applications, depending on the laying requirements, the geosynthetic roll needs to retain a certain amount of deformation allowance when unfolded. However, the working surface has a certain slope, and the tightness of the geosynthetic roll varies at the same unfolded height, affecting the laying quality. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a geotextile roll laying control system to overcome the above-mentioned defects in the existing technology, and to improve the laying quality by controlling the tilt direction of the geotextile roll to adapt to the use of different laying operation surfaces.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A geotextile roll laying control system and a geotextile roll laying device are provided, the laying device comprising: The cross arm includes two connecting ends for connecting geotextile membrane. An angle adjustment component, the angle adjustment component being used to adjust the angle between the cross arm and the horizontal plane; The control system includes An image acquisition module, mounted on the cross arm, acquires images of the geotextile roll being laid to define the laying image information. An image processing module acquires laying information based on the laying image information. The laying information includes a laying area and a suspended area. The laying area reflects the area in the laying image information where the geotextile covers the laying surface, and the suspended area reflects the area in the laying image information where the geotextile is located between the laying area and the geotextile roll. An angle adjustment module compares the laid area and the suspended area to determine whether they meet the preset corresponding conditions. If they do not meet the corresponding conditions, the module outputs an adjustment signal to the angle adjustment component to change the angle between the cross arm and the horizontal plane to meet the corresponding conditions.
[0005] In this invention, preferably, obtaining laying information based on the laying image information specifically includes: performing edge extraction on the laying image information to obtain segmented regions and edge lines. The segmented regions reflect the area range of the geotextile within the image information, and the edge lines reflect the side edges of the segmented regions along the extension direction of the geotextile. Segmentation points are obtained on the side edges, and the segmentation points reflect points on the side edges where curvature changes abruptly. Each side edge is divided into laying lines and suspended lines through the corresponding segmentation points, wherein the curvature change of the laying lines is less than that of the suspended lines. Connecting the segmentation points on two side edges forms a segmentation line segment, which divides the segmented region into a laying region and a suspended region. The laying region is specifically the area between two laying lines, and the suspended region is specifically the area between two suspended lines.
[0006] In this invention, preferably, in the step of comparing the laid area and the suspended area to determine whether they meet the preset corresponding conditions, several parallel line segments are drawn parallel to the dividing line segments. The line segment between the edge lines is taken as a reference line segment, and the midpoint of each reference line segment is taken and connected to form a line segment to be defined as the target line segment. Specifically, the corresponding condition is that the angle of the target line segment within the laid image information conforms to a preset angle range.
[0007] In this invention, preferably, the control system includes a geotextile sensor, which is used to detect the installation status of the geotextile and generate an installation completion signal to the image acquisition module. The image acquisition module receives the installation completion signal and acquires the initial image information of the geotextile. The image processing module acquires the initial image information and identifies the installation angle of the geotextile within the initial image information to define it as a reference angle, and generates a preset angle range based on the reference angle.
[0008] In this invention, preferably, the control system includes a damping adjustment module. When the suspended line meets the preset corresponding conditions, the angle adjustment module generates a tension adjustment signal to the damping adjustment module. The damping adjustment module obtains the laying information and calculates the ratio of the area of the suspended area to the area of the laid area to define the area ratio value. It judges the area ratio value against a preset area reference interval. If the area ratio value exceeds the preset area reference interval, it generates a damping increase signal until the area ratio value falls into the preset area reference interval. If the area ratio value is less than the preset area reference interval, it generates a damping decrease signal until the area ratio value falls into the preset area reference interval.
[0009] In this invention, preferably, the laying device includes two mounting shafts, each of which is rotatably connected to one of the cross arms. The mounting shafts are used to install geotextile rolls. An energized coil is provided on the cross arm, and a magnetic block is provided on the mounting shaft. When the magnetic block rotates with the mounting shaft, the energized coil provides a damping force to the magnetic block. The magnitude of the damping force is changed by adjusting the magnitude of the energized coil, and the direction of the energized coil is changed by adjusting the direction of the damping force.
[0010] In this invention, preferably, the control system includes a current matching module, which comprises a metering unit, a height measuring unit, and a current sampling unit. The metering unit measures the laying length of the geotextile roll to define it as laying length information. The height measuring unit measures the distance between the installation shaft and the laying surface to define it as laying height information. The current sampling unit acquires current information, which reflects the magnitude of the current when the area ratio falls within a preset area reference range. The current matching module acquires and obtains the correspondence between the laying length information, the laying height information, and the current information to define a preset current reference relationship. Based on the real-time measured laying height information and laying length information, the corresponding current information is matched to define the output current information, which reflects the energizing current that needs to be applied to the energized coil.
[0011] In this invention, preferably, the control system is equipped with an interval verification module. The interval verification module acquires the laying information and calculates the ratio of the area of the suspended area to the area of the laid area to define the verification area ratio. It determines whether the verification area ratio falls within a preset area reference interval. If it does, it acquires the laying length information and laying height information corresponding to the output current information and increases the confidence of the data. If it does not, it adjusts the area ratio to fall within the preset area reference interval and acquires the adjusted current information, laying length information, and laying height information as new data to re-acquire the current comparison relationship.
[0012] In this invention, preferably, the geotextile roll laying equipment includes a lifting arm and a traveling mechanism. The lifting arm is rotatable to adjust the height of the cross arm. The traveling mechanism drives the lifting arm to move. The angle adjustment component includes two linear drive members. One end of the linear drive member is rotatably mounted on one side of the lifting arm, and the other end of the linear drive member is rotatably connected to the cross arm. The linear drive members are respectively disposed on both sides of the lifting arm.
[0013] In this invention, preferably, the laying equipment includes a steering adjustment assembly, which includes a steering drive and a steering connector. One end of the steering connector is rotatably connected to the end of the lifting boom, and the other end of the steering connector is rotatably connected to the cross arm. The end of the linear drive near the lifting boom is hinged to the steering connector. The steering drive drives the steering connector to rotate, thereby rotating the cross arm.
[0014] The beneficial effects of this invention are: 1. This invention acquires the laying image information of geotextile rolls during the laying process through an image acquisition module, and uses an image processing module to acquire the laying lines and suspended lines in the laying image information. The laying area and suspended area are used to determine the laying status of the laying surface. If the corresponding conditions are not met, it indicates that there is an angle between the cross arm and the working surface. In this case, the tilt angle of the cross arm needs to be changed by adjusting the angle adjustment component until the corresponding conditions are met. This avoids uneven stress on the geotextile rolls caused by the angle between the cross arm and the working surface, thereby improving the laying quality. 2. This invention adjusts the damping force on the installation shaft during rotation by setting a damping adjustment module, thereby ensuring that the tension on the geotextile roll remains within a stable range during the laying process. This is directly reflected in the area ratio of the suspended area to the laid area, making the stress on the geotextile roll more uniform throughout the laying process and facilitating the control of the laying quality of the geotextile roll.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] Please see Figure 1-2 This embodiment provides a geotextile roll laying control system and a geotextile roll laying device. By controlling the tilt direction of the geotextile roll to adapt to different laying operation surfaces, the laying quality is improved.
[0021] First, the structure of the geotextile roll laying equipment is described in detail. The laying equipment includes a horizontal arm 4, an angle adjustment assembly, a lifting arm 3, a traveling mechanism 2, and an operating compartment 1.
[0022] The walking mechanism 2 is located at the bottom of the operating compartment 1 and is used to drive the entire laying equipment to move. In this embodiment, a tracked walking mechanism 2 is specifically adopted, with a tracked hydraulic chassis equipped with a high-torque hydraulic walking motor. The tracked chassis has strong passability and functions such as turning around in narrow roads and rotating at high speeds, and can adapt to various harsh working conditions such as deserts, mountains, hills, and mud pits. The tracked chassis has a large track width, which can use conventional flatbed trailers to transport the equipment. The engine is a six-cylinder diesel engine, which has strong power and greater torque; together with the tracked chassis, it can ensure passability and stability under various working conditions. The hydraulic oil pump uses a plunger pump, which has a more stable oil supply pressure than a gear pump, thereby improving the control accuracy and stability of the equipment; the whole vehicle uses a fully hydraulic control system, which, compared with an electric control system, can improve the load-bearing capacity of the equipment and is more suitable for laying heavy-duty roll materials.
[0023] The lifting boom 3 can rotate to adjust the height of the cross arm 4. The rotation and lifting of the lifting boom 3 are powered by a hydraulic motor. The maximum lifting capacity exceeds one ton, which can provide sufficient power for laying GCL composite components in deep trenches without causing the roll material to fall uncontrollably or be difficult to lift.
[0024] The crossarm 4 includes two connecting ends for connecting geotextile membrane. Each connecting end is provided with a mounting shaft 44, and each mounting shaft 44 is rotatably connected to one of the crossarms 4. The mounting shaft 44 is used to install the geotextile membrane, and the mounting shaft 44 is sleeved with the geotextile membrane, and the mounting shaft 44 rotates synchronously with the geotextile membrane. The crossarm 4 includes a main arm section 401 and at least one telescopic section. The telescopic section is slidably connected to the end of the main arm section 401. A telescopic drive is provided inside the crossarm 4, which drives the telescopic section and the main arm section 401 to slide relative to each other to increase or decrease the length of the crossarm 4. In this embodiment, two telescopic sections are provided on the cross arm 4. By adjusting the telescopic sections in the cross arm 4, the geotextile can be easily installed on the equipment, and the equipment can be adapted to the laying of geotextiles of different widths. By directly adjusting the telescopic sections, the equipment can install geotextiles with a width of 6 to 8 meters. In addition, by adding connecting pipes of different lengths to the ends of the cross arm 4, the equipment can be used to lay geotextiles of any narrow width.
[0025] The laying equipment includes a steering adjustment assembly, which comprises a steering drive and a steering connector 31. One end of the steering connector 31 is rotatably connected to the end of the lifting boom 3, and the other end is rotatably connected to the cross arm 4. The end of the linear drive 41 near the lifting boom 3 is hinged to the steering connector 31. The steering drive drives the steering connector 31 to rotate, thereby rotating the cross arm 4. The cross arm 4 can be adjusted up and down, forward and backward at multiple angles and rotated, enabling multi-angle installation and removal of the geotextile roll. Even if the geotextile roll is not placed evenly, the roll can be quickly installed on the equipment by adjusting the angle of the cross arm 4.
[0026] The angle adjustment assembly is used to adjust the angle between the horizontal arm 4 and the horizontal plane. The angle adjustment assembly includes two linear drive members 41. One end of each linear drive member 41 is rotatably connected to the steering connector 31, and the other end is rotatably connected to the horizontal arm 4. The linear drive members 41 are respectively disposed on both sides of the lifting arm 3. The two linear drive members 41 drive in opposite directions, allowing the tilt angle of the horizontal arm 4 to be adjusted. In this embodiment, the linear drive member 41 is specifically configured as a linear hydraulic cylinder.
[0027] A counterweight assembly is installed on the side of the operating compartment 1 away from the lifting boom 3. The counterweight assembly includes a counterweight block 11 and a sliding drive component. The counterweight block 11 is slidably connected to the operating compartment 1. The sliding drive component drives the counterweight block 11 to slide relative to the operating compartment 1 to adjust the center of gravity of the laying equipment. When a heavy geotextile roll is installed on the front cross arm 4, the counterweight block 11 can be extended, or additional counterweight blocks 11 can be added to further enhance the effect of the counterweight assembly and ensure the balance and stability of the equipment.
[0028] A meter counter 43 is installed on the cross arm 4, which is used to measure the laying length of the geotextile roll. Specifically, the meter counter 43 is a roller-type meter counter 43, which can record the unfolding and rewinding length of the geotextile roll in real time. A support arm connects the meter counter 43 to the cross arm 4, and the support arm is rotatably connected to the cross arm 4. A spring is installed between the support arm and the cross arm 4, ensuring that the roller of the meter counter 43 can fit tightly against the geotextile roll in its natural state, unaffected by the roll diameter, thus maintaining measurement accuracy. Additionally, a push rod is provided on the cross arm 4. When the roll needs to be replaced, the push rod extends to push the meter counter 43 away from the roll, facilitating the loading and unloading of the geotextile roll.
[0029] In this embodiment, please refer to Figure 3A current-carrying coil 45 is mounted on the cross arm 4, and a magnetic block 441 is mounted on the mounting shaft 44. When the magnetic block 441 rotates with the mounting shaft 44, the current-carrying coil 45 provides a damping force to the magnetic block 441. The magnitude of the damping force can be changed by adjusting the magnitude of the current flowing through the current-carrying coil 45, and the direction of the current flowing through the current-carrying coil 45 can be changed by adjusting the direction of the damping force. Specifically, the center line of the current-carrying coil 45 is set to pass through the axis of the shaft, and the magnetic pole distribution direction of the magnet is perpendicular to a certain diameter direction of the shaft. This setting simplifies the force changes on the magnetic block 441. When the magnet moves closer to or away from the coil, the damping force on the magnet is either promoting the rotation of the shaft or hindering the rotation of the shaft. The direction and magnitude of the current in the coil remain consistent.
[0030] Please refer to a geotextile roll laying control system. Figure 4-6 It includes a roll material sensor, an image acquisition module 5, an image processing module 6, and an angle adjustment module 7. The image acquisition module 5 is specifically an industrial camera 42, which is mounted on the cross arm 4. The image acquisition module 5 acquires images of the geotextile roll being laid to define the laying image information.
[0031] Image processing module 6 acquires laying information based on laying image information. Laying information includes a laying area and a suspended area. The laying area reflects the region of the geotextile covering the laying surface in the laying image information, while the suspended area reflects the region of the geotextile located between the laying area and the geotextile roll in the laying image information. Angle adjustment module 7 compares the laying area and the suspended area to determine whether they meet preset corresponding conditions. If they do not meet the corresponding conditions, it outputs an adjustment signal to the angle adjustment component to change the angle between the cross arm 4 and the horizontal plane until the corresponding conditions are met. In this embodiment, the laying state of the geotextile roll on the working surface is determined using the laying area and the suspended area, specifically by distinguishing them through the shape of the laying area and the suspended area.
[0032] Obtaining laying information based on laying image information specifically includes: edge extraction of the laying image information to obtain segmented regions and edge lines. The segmented region reflects the area of the geotextile within the image information, and the edge lines reflect the side edges of the segmented region along the geotextile's extension direction. Segmentation points are obtained on the side edges, reflecting points where curvature changes abruptly. Each side edge is divided into a laying line and a suspended line via the corresponding segmentation point. The curvature change of the laying line is less than that of the suspended line. Connecting the segmentation points on two side edges forms a segmentation line segment, which divides the segmented region into a laying region and a suspended region. The laying region specifically refers to the area between two laying lines, and the suspended region specifically refers to the area between two suspended lines. Please refer to [reference needed]. Figure 2 and Figure 3 A and A' are both paved areas, while B and B' are both suspended areas.
[0033] In the step of comparing the laid area and the suspended area to determine whether they meet the preset corresponding conditions, several parallel line segments parallel to the dividing line segments are drawn. The line segment between the edge lines is defined as the reference line segment. The midpoints of each reference line segment are taken and connected to form the target line segment. Specifically, the corresponding condition is that the angle of the target line segment within the laid image information conforms to the preset angle range. The industrial camera 42 is affected by the distance and relative position of objects during imaging. Therefore, in this embodiment, when determining whether the corresponding conditions are met, it is determined whether the preset angle range is met. This is used to reduce the error caused by the industrial camera 42 imaging, and also reduces the amount of data processing, thus improving the response speed.
[0034] The control system includes a geotextile sensor, which detects the installation status of the geotextile roll and generates an installation completion signal to the image acquisition module 5. The image acquisition module 5 receives the installation completion signal and acquires the initial image information of the geotextile roll. Considering that the length of the cross arm 4 is adjustable in this application, and that the relative position between the geotextile roll and the industrial camera 42 changes after each installation, a new preset angle range needs to be obtained after each reinstallation of the geotextile roll. The geotextile sensor can be specifically set on the connecting end of the cross arm 4. When the geotextile roll is installed, it blocks the geotextile sensor, thereby triggering the sensor. After the geotextile roll is installed, the relative position of the industrial camera 42 and the geotextile roll is determined. Therefore, the preset angle range under normal laying conditions can be obtained by using the position of the geotextile roll in the initial image information. The image processing module 6 acquires and identifies the installation angle of the geotextile roll in the initial image information as a reference angle. The reference angle is specifically the angle between the generatrix of the geotextile roll and one of the edges of the initial image information. A preset angle range is generated based on a reference angle. There is a pre-defined correspondence between the preset angle range and the reference angle. The smaller the reference angle, the closer the installation direction of the industrial camera 42 is to the perpendicular direction of the geotextile roll axis, and the smaller the size of the preset angle range. For example, if the reference angle is 3 degrees, the corresponding preset angle range is set to (92, 94); if the reference angle is 10 degrees, the corresponding preset angle range is set to (98.5, 101.5).
[0035] There is resistance during the actual rotation of the mounting shaft 44. This resistance is affected by its own weight and rotation speed. In other words, as the length of the geotextile roll is extended, the weight and diameter of the geotextile roll will change. Therefore, when it is necessary to maintain the current rotation state, the magnitude of the damping force on the mounting shaft 44 needs to be adjusted.
[0036] In this invention, preferably, the control system includes a damping adjustment module 8. When the suspended line meets the preset corresponding conditions, the angle adjustment module 7 generates a tension adjustment signal to the damping adjustment module 8. The damping adjustment module 8 acquires the laying information and calculates the area ratio of the suspended area and the laid area as the area ratio value. It then judges the area ratio value against a preset area reference interval. If the area ratio value exceeds the preset area reference interval, a damping increase signal is generated until the area ratio value falls into the preset area reference interval. If the area ratio value is less than the preset area reference interval, a damping decrease signal is generated until the area ratio value falls into the preset area reference interval. This invention adjusts the damping force experienced by the installation shaft 44 during rotation by setting the damping adjustment module 8, thereby ensuring that the tension on the geotextile roll remains within a stable range during the laying process. This tension is directly reflected in the area ratio of the suspended area and the laid area, resulting in more uniform stress on the geotextile roll throughout the laying process and facilitating control of the geotextile roll laying quality.
[0037] In this invention, preferably, the control system includes a current matching module 9, which includes a meter counting unit, a height measuring unit, and a current sampling unit. The meter counting unit measures the laying length of the geotextile roll to define the laying length information. Specifically, the meter counting unit is a meter counter 43. The height measuring unit measures the distance between the installation shaft 44 and the laying surface to define the laying height information. The current sampling unit acquires current information, which reflects the magnitude of the current when the area ratio falls within a preset area reference range. The current matching module 9 acquires and obtains the correspondence between the laying length information, the laying height information, and the current information to define a preset current reference relationship. Based on the real-time measured laying height information and laying length information, the corresponding current information is matched to define the output current information. The output current information reflects the energizing current that the energizing coil 45 needs to apply.
[0038] In this invention, preferably, the control system is equipped with an interval verification module 10. The interval verification module 10 acquires the laying information and calculates the ratio of the area of the suspended area to the area of the laid area to define the verification area ratio. It determines whether the verification area ratio falls within a preset area reference range. If it does, it acquires the laying length information and laying height information corresponding to the output current information and increases the confidence of the data. If it does not, it adjusts the area ratio to fall within the preset area reference range and acquires the adjusted current information, laying length information, and laying height information as new data to re-acquire the current comparison relationship.
[0039] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.

The current sampling unit acquires current information, which reflects the magnitude of the current when the area ratio falls within a preset area reference range. The current matching module (9) acquires and obtains the correspondence between the laying length information, the laying height information, and the current information to define a preset current reference relationship. Based on the real-time measured laying height information and laying length information, the corresponding current information is matched to define the output current information. The output current information reflects the energizing current that the energizing coil (45) needs to apply.
8. The geotextile roll laying control system according to claim 7, characterized in that: The control system is equipped with an interval verification module (10). The interval verification module (10) acquires the laying information and calculates the ratio of the area of the suspended area to the area of the laid area to define the verification area ratio. It determines whether the verification area ratio falls within a preset area reference range. If it does, it acquires the laying length information and laying height information corresponding to the output current information and increases the confidence of the data. If it does not, it adjusts the area ratio to fall within the preset area reference range and acquires the adjusted current information, laying length information and laying height information as new data to re-acquire the current comparison relationship.
