Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of landslide testing, and in particular to a landslide testing device with controllable parameters. Background Art
[0002] High-level and high-speed landslides are a natural disaster that is different from ordinary landslides. They have the characteristics of long movement distance, large degree of damage, and complex disaster-causing forms. They are often accompanied by chain disaster processes such as landslide surges and landslide blocking rivers. However, high-level and high-speed landslides have different mechanical behaviors from low-speed and short-range small landslides, and cannot be directly simulated using conventional landslide test devices. At present, conventional landslide tests mainly rely on gravity to accelerate the sliding body on a fixed slope. This requires a large acceleration distance to be reserved for the test sliding body to construct a large-scale and long-distance conventional landslide test device, which has problems such as high construction difficulty, low space utilization, and high site or material costs. In addition, conventional landslide tests use fixed slopes for gravity acceleration, and cannot set the movement speed and movement angle of the sliding body. The sliding body shape is not fixed when an actual high-speed landslide occurs, and due to the existence of sliding friction and air resistance, there is an upper limit to the acceleration effect brought by gravity to the sliding body structure, which reduces the accuracy of the test results. Summary of the invention
[0003] The present disclosure proposes a parameter-controllable landslide test device to solve the technical problems in the above-mentioned landslide test, such as the non-fixed sliding body shape, low accuracy of test results and high cost, to a certain extent.
[0004] The present disclosure provides a parameter-controllable landslide test device, comprising:
[0005] Track panels, including tracks;
[0006] A box body, comprising box body power wheels and a rolling bottom plate for loading the test object, wherein the box body power wheels are located on the track;
[0007] A driving device, disposed on the box, for driving the box power wheel to drive the box to move along the track at a preset speed;
[0008] A movable top plate is arranged on the top of the box body;
[0009] A shape maintaining module, one end of which is detachably fixed to the movable top plate, and the other end of which is used to maintain the contour shape of the test object;
[0010] When the box moves along the track to a preset position of the track, the movable top plate is moved to separate the shape retaining module from the movable top plate, and the test object continues to move with the box on the rolling bottom plate based on the preset speed to perform a landslide test.
[0011] As can be seen from the above, the parameter-controllable landslide test device provided by the present disclosure is equipped with a power wheel and a rolling bottom plate for loading the test object through a box body, and the power wheel is located on the track and driven by a driving device arranged on the box body to ensure that the box body moves along the track at a preset speed. The movable top plate is installed on the top of the box body, and one end of the shape holding module is detachably fixed on the movable top plate, and the other end is used to maintain the contour shape of the test object. When the box body moves to a preset position along the track, the shape holding module and the movable top plate are separated by moving the movable top plate, so that the test object continues to move with the box body on the rolling bottom plate to perform a landslide test. This design uses the motor-driven acceleration method to break through the speed limit of the traditional landslide simulation device, greatly reduce the size required for the acceleration device, and enable the sliding body structure to achieve higher acceleration in a shorter distance. Through technical means such as short-distance acceleration, inclination control and shape retention, high acceleration and precise control of the sliding body structure in the landslide simulation test are achieved. Compared with traditional landslide simulation devices, it can not only significantly reduce the required space size, but also ensure that the sliding structure is tested in a predetermined shape and angle, thereby improving the accuracy and reliability of the test.

[0023] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0024] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0025] At present, conventional landslide tests mainly rely on gravity to accelerate the sliding body on a fixed slope. This acceleration method requires a large acceleration distance to be reserved for the test sliding body, which places high demands on the size of the test equipment. However, the construction of a large-scale, long-distance conventional landslide test device has problems such as high construction difficulty, low space utilization, and high site or material costs. Therefore, it is impossible to manufacture this conventional landslide test device in the actual test process. In terms of test speed, the sliding body test device that uses a fixed slope for gravity acceleration cannot set the movement speed and movement angle of the sliding body, and due to the existence of sliding friction and air resistance, there is an upper limit to the acceleration effect brought by gravity to the sliding body structure. At the same time, the problem of maintaining the shape of the sliding body during high-speed movement is also a link that is not considered in detail in conventional sliding body tests. The shape of the sliding body is not fixed when an actual high-speed landslide occurs. It is necessary to test the different possible shapes of sliding body structures under extreme movement conditions to obtain accurate test results under different sliding body shape conditions.
[0026] In the prior art, the high-speed debris flow simulation device uses the method of accelerating the natural sliding of soil along a fixed inclined slope. The test speed of this type of landslide test is limited to a fixed value. When the sliding body or debris flow material reaches the end of the slope, it is difficult for the test material to form a certain thickness. The test speed of this device is fixed and cannot be adjusted, and it is difficult for the test material to maintain a certain shape or spatial volume. The single underwater landslide simulation device is not much different from the former. The environmental medium is changed from air to water. There are also problems such as the single uncontrollable debris flow test speed and poor ability to maintain the sliding body shape. The fixed-angle soil natural acceleration landslide surge device simulates landslide disasters and subsequent surge disaster chains. Although the device takes into account the entry of a sliding body of a certain volume into the water, the entry speed of the test sliding body is uncontrollable, and the sliding body shape is fixed to a cubic shape, which is quite different from the real sliding body shape. A pneumatically propelled feeding device was designed on the track, which can achieve short-distance acceleration of the slider to a certain extent. However, the maximum effective slider acceleration distance of the device is only 1.235m and the pneumatic propulsion efficiency is limited. It cannot simulate the situation of the slider at extreme movement speed. In addition, the device cannot set the shape and size of the slider, and the test conditions are relatively simple.
[0027] It can be seen that most of the current soil model tests based on landslides are carried out by fixing the inclination of the landslide and allowing the sliding body to fall naturally under the action of gravity, so there is a problem of uncontrollable fixed speed. Generally, when the sliding body or debris flow material reaches the end of the slope, it is difficult for the test material to form a certain thickness, and the disaster chain such as landslide surge usually occurs when a large volume of soil enters the water at the beginning, so the test soil needs to have a certain shape or spatial volume. Therefore, how to accelerate the soil structure to the required motion state (speed, angle, etc.) in a short time and short distance; how to shape and fix the soil state according to the test requirements; how to enable the sliding body to maintain the established volume and target shape when accelerating to the required motion state, and improve the accuracy of the test have become technical problems that need to be solved urgently.
[0028] In view of this, the embodiment of the present disclosure provides a parameter-controllable landslide test device, in which a power wheel and a rolling bottom plate for loading a test object are installed through a box body, and the power wheel is located on a track and driven by a driving device arranged on the box body to ensure that the box body moves along the track at a preset speed. A movable top plate is installed on the top of the box body, and one end of the shape holding module is detachably fixed on the movable top plate, and the other end is used to maintain the contour of the test object. When the box body moves to a preset position along the track, the shape holding module and the movable top plate are separated by moving the movable top plate, so that the test object continues to move with the box body on the rolling bottom plate to perform a landslide test. This design uses a motor-driven acceleration method to break through the speed limit of a traditional landslide simulation device, greatly reducing the size required for the acceleration device, so that the sliding body structure can achieve a higher acceleration in a shorter distance. Through technical means such as short-distance acceleration, inclination control and shape retention, high acceleration and precise control of the sliding body structure in a landslide simulation test are achieved. Compared with traditional landslide simulation devices, it can not only significantly reduce the required space size, but also ensure that the sliding structure is tested in a predetermined shape and angle, thereby improving the accuracy and reliability of the test.
[0029] See also Figure 1 , Figure 1 A schematic diagram of a landslide test device with controllable parameters according to an embodiment of the present disclosure is shown. Figure 1 The parameter-controllable landslide test device includes:
[0030] Track panels, including tracks;
[0031] A box body, comprising box body power wheels and a rolling bottom plate for loading the test object, wherein the box body power wheels are located on the track;
[0032] A driving device, disposed on the box, for driving the box power wheel to drive the box to move along the track at a preset speed;
[0033] A movable top plate is arranged on the top of the box body;
[0034] A shape maintaining module, one end of which is detachably fixed to the movable top plate, and the other end of which is used to maintain the contour shape of the test object;
[0035] When the box moves along the track to a preset position of the track, the movable top plate is moved to separate the shape retaining module from the movable top plate, and the test object continues to move with the box on the rolling bottom plate based on the preset speed to perform a landslide test.
[0036] Specifically, see Figure 1-Figure 2 , Figure 1-Figure 2 A schematic diagram of a landslide test device with controllable parameters according to an embodiment of the present disclosure is shown. Figure 1-Figure 2 In the present invention, the model box body 1 is used as the main loading device of the experimental object, and the driving motor 2 at the rear drives the model box power wheel 3 to control the speed. The spring telescopic rod 4 is used to connect the model box body 1 and the openable box door 9. The openable box door 9 can rotate around the box-door hinge element 5 around the hinge point under the action of the spring telescopic rod 4 to achieve opening and closing. After the openable box door 9 is closed, the L-shaped buckle 6 is used to buckle the L-shaped buckle block 7 to stabilize the openable box door 9 in the closed state. The track panel trigger block 8 is fixed on the movable track panel 15. The track panel trigger block 8 and the inclined surface of the L-shaped buckle 6 are parallel. When the model box 1 moves forward (in the direction of the box door), the inclined surfaces of the L-shaped buckle 6 and the track panel trigger block 8 are parallel. The L-shaped buckle 6 bounces upward around the L-shaped lock hinge 22, and the L-shaped buckle 6 is separated from the L-shaped buckle block 7, so that the open box door 9 can be opened. Since the open box door 9 is hinged with the movable top plate 11 by the box door-top plate transmission rod 10, the movable top plate 11 is pushed backward when the open box door 9 is opened, so that the top plate-limiting rod self-locking structure 12 is unlocked, and the soil model 37 is released from the constraint. The box structure model box moves forward along the model box running track 13 under the traction of the power wheel 3. After the open box door 9 is opened, the model box body 1 contacts the end damper 14 and quickly stops. The unconstrained soil model 37 moves forward along the model box rolling bottom plate 18 at a predetermined speed. The model box rolling bottom plate 18 is composed of a roller group structure 19 and a roller group transmission belt 20. While being able to stably load the soil model 37, it can also maximize the movement state of the soil model 37 when it is out of the box.
[0037] In some embodiments, the shape maintaining module includes:
[0038] A limiting plate, used to limit the contour of the test object;
[0039] A main rod with a toothed portion, used for detachably fixing the limit plate to the movable top plate;
[0040] The first connecting member is used to rotatably connect the limit plate and the main rod so that the angle formed between the limit plate and the main rod is in the range of 0 to 180 degrees.
[0041] Specifically, see Figure 3-Figure 4 , Figure 3-Figure 4 A schematic diagram of a form maintaining module according to an embodiment of the present disclosure is shown. Figure 3-Figure 4 In the figure, the soil shape maintaining module unit body is composed of a shape fixing module main rod 32, a main rod-limiting plate hinge structure 33, and a soil limiting plate 34. The shape fixing module main rod 32 is controlled to constrain the soil model 37 below. The soil limiting plate 34 can rotate along the main rod-limiting plate hinge structure 33. Multiple soil shape maintaining module unit bodies together constitute a shape maintaining module 36, which can realize the constraints on soil models 37 of different shapes and sizes.
[0042] In some embodiments, the movable top plate includes a through hole matching the shape maintaining module and a top plate limiting device; wherein the top plate limiting device includes:
[0043] A top plate limiting module, fixedly arranged on the movable top plate;
[0044] An elastic member, one end of which is fixedly disposed on the top plate limiting module;
[0045] A one-way limiting module is disposed at the other end of the elastic member and meshes with the toothed portion of the main rod passing through the through hole to ensure that the main rod moves downward in one direction, thereby maintaining the limit of the contour of the test object by the limiting plate unchanged;
[0046] A second connecting member, used to connect the one-way limiting module and the movable top plate;
[0047] When the main rod moves downward, the one-way limiting module moves clockwise from the initial position to a first angle, and the elastic member and the top plate limiting module cause the one-way limiting module to rebound to the initial position.
[0048] In some embodiments, the top plate limiting module includes a first limiting portion and a second limiting portion which are arranged perpendicular to each other, the first limiting portion is arranged perpendicularly to the movable top plate, the second limiting portion is arranged parallel to the movable top plate, the cross section of the first limiting portion is a trapezoid and the lower side of the trapezoid is arranged on the movable top plate, the cross section of the second limiting portion is a square, and the cross section of the one-way limiting module is a triangle;
[0049] One end of the elastic member is fixed to one side of the first limiting portion close to the toothed portion, and the other end of the elastic member is fixed to the first right-angle surface of the one-way limiting module, and the elastic member and the second limiting portion are located on the same side of the first limiting portion;
[0050] The second right-angle surface of the one-way limiting module is connected to the movable top plate through the second connecting member, and the inclined surface of the one-way limiting module is engaged with the toothed portion.
[0051] Specifically, see Figure 5-Figure 6 , Figure 5 A schematic diagram of a movable top plate according to an embodiment of the present disclosure is shown, Figure 6 A schematic diagram of a top plate limiting module according to an embodiment of the present disclosure is shown. Figure 5-Figure 6In the figure, the top plate-limit rod self-locking structure 12 is composed of a main rod 32 of a shape fixing module, a limiter module 39, a spring module 40, and a one-way restriction module 41. The existence of the main rod tooth groove 35 enables the one-way restriction module 41 to mesh during the movement of the main rod 32 of the shape fixing module. During the downward movement of the main rod 32 of the shape fixing module, the one-way restriction module 41 rotates clockwise. The spring module 40 and the limiter module 39 cooperate to ensure that the one-way restriction module 41 rebounds in time after a small angle rotation. The bottom of the one-way restriction module 41 meshes with the horizontal plane of the main rod tooth groove 35 to limit the one-way movement of the main rod 32 of the shape fixing module.
[0052] In some embodiments, the device also includes: a box door, rotatably disposed on the box body and connected to the movable top plate; wherein the box door pushes the movable top plate to move during rotation, so that the one-way restriction module is separated from the toothed portion of the main rod, thereby separating the limit plate and the test object.
[0053] Specifically, see Figure 7 , Figure 7 A schematic diagram of a cabinet door according to an embodiment of the present disclosure is shown. Figure 7 In the figure, a transmission module connecting groove 21 is provided on the top of the open door 9 to connect the spring telescopic rod 4 and the door-top plate transmission rod 10. The spring telescopic rod 4 and the door-top plate transmission rod 10, and the open door 9 can all move around the hinge module of the connecting groove 21; the specific structure of the L-shaped buckle 6 can be divided into three parts: an L-shaped lock buckle hinge point 22, an L-shaped lock buckle main body 23 and an elastic limiting module 24 at the tail of the lock buckle, wherein the remaining structure can move around the L-shaped lock buckle hinge point 22, and the elastic limiting module 24 at the tail of the lock buckle is made of elastic material, which is used to engage with the L-shaped buckle block 7 to achieve structural interlocking.
[0054] In some embodiments, the door comprises:
[0055] A box door connecting piece, used for rotatably fixing the box door to the box body;
[0056] A rotatable fixing member, comprising a first end rotatably fixed to the box door, and a second end connected to the first end, wherein the second end has a first inclined surface;
[0057] A first connection end is connected to the side of the box body through an elastic telescopic member;
[0058] The second connecting end is connected to the movable top plate through a transmission rod.
[0059] In some embodiments, the housing further comprises:
[0060] A stopper is arranged on the side surface of the box body and matches the rotatable fixing member, and is used to limit the rotation of the rotatable fixing member so as to fix the box door on the box body.
[0061] Specifically, see Figure 8A-B , Figure 8A-B Schematic diagram of a rotatable fixing member according to an embodiment of the present disclosure is shown. Figure 9-10 , Fig. 9 A schematic diagram of an elastic telescopic member according to an embodiment of the present disclosure is shown. Fig.10 The schematic diagram of the transmission rod according to the embodiment of the present disclosure is shown. The transmission module is divided into a spring telescopic rod 4 and a box door-top plate transmission rod 10, wherein the spring telescopic rod 4 is composed of a fixed section 25 and a telescopic section 26, the fixed section 25 is hinged to the side of the model box body 1 by the fixed section hinge end 27, and the telescopic section hinge end is hinged to the transmission module connection groove 21; the box door-top plate transmission rod 10 is a rigid structure, composed of a transmission rod body 29, a transmission rod-top plate hinge end 30 and a transmission rod-box door hinge end 31, the transmission rod-top plate hinge end 30 is arranged on the top of the model box body 1, and the transmission rod-box door hinge end 31 is hinged to the transmission module connection groove 21.
[0062] In some embodiments, the apparatus further comprises:
[0063] The track panel limiter is arranged on the track panel and matches the rotatable fixing part and has a second inclined surface; wherein, when the box body moves to the preset position on the track, the second inclined surface of the track panel limiter contacts the first inclined surface, and the second inclined surface pushes the rotatable fixing part to rotate and separate from the stopper, so that the box door rotates around the box door connecting part, driving the transmission rod to push the movable top plate to move.
[0064] In some embodiments, a track limiter is provided at the end of the track; when the box moves along the track to the track limiter, the box stops moving, and the test object continues to move on the rolling base at the preset speed.
[0065] Specifically, see Figure 11-13 , Figure 11-13The schematic diagram of the principle of the landslide test device according to the embodiment of the present disclosure is shown. During the forward movement (door direction) of the model box 1, the inclined surfaces of the L-shaped buckle 6 and the track panel trigger block 8 contact each other, causing the L-shaped buckle 6 to bounce upward around the L-shaped lock buckle hinge 22, realizing the separation of the L-shaped buckle 6 from the L-shaped buckle block 7, and allowing the open door 9 to be opened. Since the open door 9 is hinged to the movable top plate 11 by the door-top plate transmission rod 10, the movable top plate 11 is pushed backwards while the open door 9 is opened, so that the top plate-limiting rod self-locking structure 12 is unlocked, and the constraint of the soil model 37 is released. The box structure model box moves forward along the model box running track 13 under the traction of the power wheel 3. After the open door 9 is opened, the model box body 1 contacts the end damper 14 and quickly stops, and the unconstrained soil model 37 moves forward along the model box rolling bottom plate 18 at a predetermined speed. Fig.14 As shown, Fig.14 A schematic diagram of a rolling base plate according to an embodiment of the present disclosure is shown. Fig.14 In the figure, the rolling base plate 18 may include a roller group structure 19 and a roller group drive belt 20. The slope test device disclosed in the present invention can simulate a high-speed sliding body. Therefore, the test object (such as a soil structure) has a relatively high speed and can move forward by inertia. Thus, separation is achieved based on the speed difference between the "model box after deceleration" and the "soil model that continues to move forward by inertia". A roller group and a track structure wrapped around a roller group are provided at the bottom to make the separation smoother.
[0066] In some embodiments, the apparatus further comprises:
[0067] A device bottom plate is arranged below the track panel;
[0068] An angle adjuster is arranged between the device bottom plate and the track panel and is used for adjusting the angle of the device bottom plate.
[0069] Specifically, see Fig.15 , Fig.15 A schematic diagram of the bottom plate of the device according to an embodiment of the present disclosure is shown. During the test, the angle of the movable track panel 15 is adjusted along the panel-bottom plate articulation module 16 to control the movement angle of the soil model 37. The angle of the track panel 15 can be any angle and can be set as needed. The bottom plate 17 of the device is rigidly connected to the ground to ensure the stability of the device as a whole during the test. It should be understood that the length of the track system can be designed according to the test requirements, and the track inclination can be adjusted using the track inclination adjustment hydraulic rod 42 according to the test requirements.
[0070] It can be seen that the landslide test device implemented according to the present disclosure further proposes short-distance acceleration, inclination control, shape maintenance and other technologies or methods on the basis of the traditional landslide simulation device. The speed limit of the sliding structure in the conventional landslide test is broken through by the motor-driven acceleration method, which greatly reduces the required size of the landslide acceleration device, and achieves the purpose of using a smaller size than the conventional landslide device to enable the sliding structure to obtain a higher acceleration during the test. At the same time, the sliding shape maintenance device and the chute inclination control device are combined to ensure that the sliding structure can perform the required test in a predetermined shape and angle. Furthermore, the landslide device is used as a starting device for high-speed and high-position landslide disaster simulation experiments. The device can also be further used to simulate disaster chains such as landslide surges, landslide blocking rivers, and impact damage to highway and bridge models, providing strong technical support for the research and prevention of landslide disasters.
[0071] It should be noted that the structural quantity and scale of each structural component disclosed in the present invention can be designed according to actual test requirements, such as using a larger model box size, adopting more soil shape fixing modules, using a three-dimensional soil module fixing scheme, changing the test track angle or size, using a curved fixed baffle, using it underwater or in a vacuum environment, using the above-mentioned device as a disaster chain starting condition, etc. The above-mentioned non-essential modifications based on the description of the present invention still follow the technical solution proposed in the present invention and are also within the scope of the technical solution of the present invention.

In addition, the device can be shown in the form of a block diagram to avoid making the embodiments of the present disclosure difficult to understand, and this also takes into account the fact that the details of the implementation of these block diagram devices are highly dependent on the platform on which the embodiments of the present disclosure will be implemented (that is, these details should be fully within the scope of understanding of those skilled in the art).
