Description

Technical Field

[0001] The present application relates to the technical field of test devices, and more particularly, to a model test tank. Background Art

[0002] In the field of model test technology, traditional model test tanks are generally divided into two types. One is a model test tank with a fixed and non-adjustable slope, and the other is a model test tank that can only move the entire slope as a whole to adjust the slope. This makes the existing model test tanks can only simulate relatively simple slope forms, but it is difficult to simulate more complex terrains, and the test results obtained when studying soil sliding and erosion deviate greatly from the actual situation. Utility Model Content

[0003] The purpose of the present application is to provide a model test tank for at least one technical problem involved in the background art.

[0004] To achieve the above object, the present application adopts the following technical solutions:

[0005] The present application provides a model test tank, including a tank body and a plurality of hydraulic units. The tank body has a bottom slot opening. Each hydraulic unit is located below the tank body. The hydraulic unit includes a hydraulic drive and a soil-bearing platform. The soil-bearing platform is located above the hydraulic drive. The output shaft of the hydraulic drive is vertically connected to the soil-bearing platform. Each soil-bearing platform is located within the bottom slot opening, and the top surfaces of each soil-bearing platform are arranged in the same horizontal plane to cover the bottom slot opening.

[0006] Optionally, each of the hydraulic units is arranged in sequence in a first direction, and the first direction is the length direction of the tank body.

[0007] The beneficial effect of this technical solution is that in this way, the model test tank can simulate a slope extending in the first direction.

[0008] Optionally, each of the hydraulic units is divided into a first hydraulic unit and a second hydraulic unit. The soil-bearing platform of the second hydraulic unit has an installation end disposed close to the first hydraulic unit. The second hydraulic unit includes a soil-bearing plate. In the first direction, one end of the soil-bearing plate is a pivot end pivotally connected to the installation end, and the other end of the soil-bearing plate is a lapping end, and the lapping end laps on the top surface of the soil-bearing platform of the first hydraulic unit.

[0009] The beneficial effect of this technical solution is that in this way, when the second hydraulic unit moves up and down relative to the first hydraulic unit, the inclination angle of the plate surface of the corresponding soil-bearing plate will change, and thus the slope of the corresponding slope surface will change.

[0010] Optionally, the model test tank provided by the embodiments of the present application includes one first hydraulic unit and multiple second hydraulic units. In the first direction, the first hydraulic unit is located on one side of each second hydraulic unit. The soil-bearing plate of the second hydraulic unit that is arranged away from the first hydraulic unit among two adjacent second hydraulic units overlaps the soil-bearing platform of another second hydraulic unit, and the soil-bearing plate of the second hydraulic unit closest to the first hydraulic unit overlaps the soil-bearing platform of the first hydraulic unit.

[0011] The beneficial effect of this technical solution is as follows: In this way, since the soil-bearing plate overlaps with the adjacent soil-bearing platform, from the first hydraulic unit to the second hydraulic unit farthest from the first hydraulic unit, the slopes formed by each soil-bearing plate and each soil-bearing platform gradually increase. Furthermore, a slope with a relatively large slope length and a relatively large slope angle is simulated. Moreover, the height of the slope corresponding to the position of the first hydraulic unit and each second hydraulic unit can also be changed accordingly, so that the entire slope presents a undulating shape, and thus is closer to the actual slope situation in nature.

[0012] Optionally, the model test tank provided by the embodiments of the present application further includes a hydraulic chamber. Each hydraulic unit is arranged in the hydraulic chamber. The top of the hydraulic chamber is communicated with the bottom slot opening. An operation port is arranged on the side of the hydraulic chamber, and a hydraulic chamber cover plate is arranged on the operation port.

[0013] The beneficial effect of this technical solution is as follows: In this way, the hydraulic chamber can provide a certain protection for the hydraulic unit, so that the hydraulic unit is not easily damaged in a relatively complex test environment. When it is necessary to repair or replace components of the hydraulic unit, the hydraulic chamber cover plate can be flipped or removed to perform repairs or replacements through the operation port.

[0014] Optionally, the hydraulic unit further includes a telescopic support. The telescopic support includes multiple telescopic modules. Each telescopic module is arranged and connected in sequence in the vertical direction. The telescopic module located at the uppermost position is pivotally connected to the soil-bearing platform, and the telescopic module located at the lowermost position is pivotally connected to the hydraulic chamber.

[0015] The beneficial effect of this technical solution is as follows: In this way, the soil-bearing platform and the soil body can be supported by the telescopic support during the movement of the soil-bearing platform.

[0016] Optionally, the telescopic module includes a first support rod and a second support rod. The middle parts of the first support rod and the second support rod are pivotally connected. The top ends of the first support rod and the second support rod in the uppermost telescopic module are both in sliding fit with the soil-bearing platform. The top end of the first support rod and the bottom end of the second support rod in the lowermost telescopic module are both in sliding fit with the hydraulic chamber. The first support rod of the telescopic module located above in two adjacent telescopic modules is pivotally connected to the second support rod of the telescopic module located below, and the second support rod of the telescopic module located above is pivotally connected to the first support rod of the telescopic module located below.

[0017] The beneficial effect of this technical solution is as follows: In this way, a telescopic module with high strength and stable telescoping is formed by the two support rods, namely the first support rod and the second support rod. By combining multiple telescopic modules to form a structure with greater strength, it can provide relatively stable and reliable support and guidance for the soil-bearing platform and the soil mass.

[0018] Optionally, the model test tank provided in the embodiment of the present application further includes a support base and a plurality of universal wheels. The hydraulic chamber is fixed to the top end of the support base, and each universal wheel is fixed to the bottom of the support base of the model test tank.

[0019] The beneficial effect of this technical solution is as follows: In this way, it is convenient to support the soil mass, the tank body and the hydraulic chamber, and to move through each universal wheel.

[0020] Optionally, the model test tank provided in the embodiment of the present application further includes two side movable baffles and a movable back panel, both of which are used to be arranged above the tank body. The top of the tank body is provided with a filling opening having the same area as the bottom end opening. The filling opening has a first edge extending in a first direction and a second edge extending in a second direction. One end of the movable back panel is hinged to the second edge, one end of one side movable baffle is hinged to one first edge, and one end of the other side movable baffle is hinged to the other first edge. Both side movable baffles are detachably connected to the movable back panel.

[0021] The beneficial effect of this technical solution is as follows: In this way, the hydraulic unit can jack up the soil mass into the space enclosed by the movable baffles and the movable back panel, increasing the height of the slope that can be formed inside the model test tank. When it is not necessary to make the height of the top end of the slope higher than the tank body, it is only necessary to separate the movable baffles from the movable back panel and rotate and lower the movable baffles and the movable back panel with the hinge position as the axis. The hinge connection is achieved through a hinge.

[0022] Optionally, the side movable baffles, the movable back panel and the tank body are all made of a transparent structure.

[0023] The beneficial effects of this technical solution are as follows: In this way, it is convenient to observe the soil sample structure layer in the model test tank. The side movable baffle, the movable back plate and the tank body can also adopt steel pipes or angle irons as the frames.

[0024] The technical solution provided by this application can achieve at least one of the following beneficial effects:

[0025] For the model test tank provided by this application, during use, the top surfaces of the soil-bearing platforms of the hydraulic unit are in the same horizontal plane. Put a sufficient amount of soil in the tank body and cover the top surfaces of the soil-bearing platforms with the soil. When it is necessary to change the slope at a certain position in the tank body, the hydraulic driving parts in the corresponding position of the hydraulic unit can be controlled to lift the corresponding soil-bearing platform. Since the hydraulic unit includes multiple hydraulic units, the hydraulic driving parts can be started at multiple positions in the tank body to change the soil slope; compared with the existing model test tanks, the model test tank provided by this application can provide more forms of soil slopes during the test process and obtain test results closer to the actual situation of the natural environment.

[0046] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0047] As Figures 1 to 5 shown, the present application provides a model test tank, including a tank body 04 and a plurality of hydraulic units. The tank body 04 has a bottom tank opening. Each of the hydraulic units is located below the tank body 04. The hydraulic unit includes a hydraulic drive member 19 and a soil bearing platform 14. The soil bearing platform 14 is located above the hydraulic drive member 19. The output shaft of the hydraulic drive member 19 is vertically connected to the soil bearing platform 14. Each of the soil bearing platforms 14 is located within the bottom tank opening. The top surfaces of each of the soil bearing platforms 14 are arranged in the same horizontal plane to cover the bottom tank opening.

[0048] In an embodiment of the present application, the model test tank includes at least three of the hydraulic units. In an embodiment of the present application, the hydraulic drive member 19 is preferably a controllable hydraulic telescopic rod or an oil cylinder.

[0049] When the model test tank provided by the present application is in use, the top surfaces of the soil bearing platforms 14 of the hydraulic units are in the same horizontal plane. Soil in an amount that meets the experimental requirements is placed in the tank body 04, and the soil covers the top surfaces of each of the soil bearing platforms 14. When it is necessary to change the slope at a certain position in the tank body 04, the hydraulic drive member 19 in the corresponding position hydraulic unit can be controlled to lift the corresponding soil bearing platform 14. Since the hydraulic unit includes a plurality of hydraulic units, the hydraulic drive members 19 can be activated at multiple positions in the tank body 04 to change the soil slope; compared with the existing model test tanks, the model test tank provided by the present application can provide more forms of soil slopes during the test process and obtain test results closer to the actual situation of the natural environment.

[0050] Optionally, each of the hydraulic units is arranged in sequence in a first direction, and the first direction is the length direction of the tank body 04. In this way, the model test tank can simulate a slope extending in the first direction. Of course, the soil bearing platforms 14 of each hydraulic unit can be arranged in a matrix within the bottom tank opening to simulate slopes appearing in multiple directions.

[0051] Optionally, each of the hydraulic units is divided into a first hydraulic unit 16 and a second hydraulic unit 05. The soil-bearing platform 14 of the second hydraulic unit 05 has an installation end disposed close to the first hydraulic unit 16. The second hydraulic unit 05 includes a soil-bearing plate 15. One end of the soil-bearing plate 15 in the first direction is a pivoting end pivotally connected to the installation end, and the other end of the soil-bearing plate 15 is a lapping end, which lapps on the top surface of the soil-bearing platform 14 of the first hydraulic unit 16. In this way, when the second hydraulic unit 05 moves up and down relative to the first hydraulic unit 16, the inclination angle of the plate surface of the corresponding soil-bearing plate 15 will change, thereby changing the slope of the corresponding slope surface. Of course, an elastic layer covering each soil-bearing platform 14 can also be used instead of the soil-bearing plate 15. The elastic layer also covers the entire bottom slot. When the soil-bearing platform 14 moves up and down, the elastic layer changes accordingly, thereby driving the soil mass on the elastic layer to generate a slope change.

[0052] Optionally, the model test tank provided by the embodiment of the present application includes one first hydraulic unit 16 and a plurality of second hydraulic units 05. In the first direction, the first hydraulic unit 16 is located on one side of each of the second hydraulic units 05. The soil-bearing plate 15 of the second hydraulic unit 05 that is disposed away from the first hydraulic unit 16 in each adjacent pair of the second hydraulic units 05 lapps on the soil-bearing platform 14 of another second hydraulic unit 05, and the soil-bearing plate 15 of the second hydraulic unit 05 closest to the first hydraulic unit 16 lapps on the soil-bearing platform 14 of the first hydraulic unit 16. In this way, since the soil-bearing plate 15 lapps on the adjacent soil-bearing platform 14, from the first hydraulic unit 16 to the second hydraulic unit 05 farthest from the first hydraulic unit 16, the slopes formed by each soil-bearing plate 15 and each soil-bearing platform 14 gradually rise, thereby simulating a slope surface with a relatively large slope length and a relatively large slope angle. Moreover, the height of the slope surface corresponding to the position of the first hydraulic unit 16 and each second hydraulic unit 05 can also be changed accordingly, so that the entire slope surface presents a undulating shape, thereby being closer to the actual slope surface in nature.

[0053] Optionally, the model test tank provided by the embodiment of the present application further includes a hydraulic chamber 09. Each of the hydraulic units is disposed in the hydraulic chamber 09. The top of the hydraulic chamber 09 is communicated with the bottom slot. An operation port is provided on the side of the hydraulic chamber 09, and a hydraulic chamber cover plate 06 is provided on the operation port. In this way, the hydraulic chamber 09 can provide a certain protection for the hydraulic unit, making the hydraulic unit not easily damaged in a relatively complex test environment. When it is necessary to repair or replace components of the hydraulic unit, the hydraulic chamber cover plate 06 can be flipped or removed to perform repairs or replacements through the operation port.

[0054] Optionally, the hydraulic unit further includes a telescopic support 13, which includes a plurality of telescopic modules. The telescopic modules are arranged in the vertical direction and connected in sequence. The telescopic module at the uppermost position is pivotally connected to the soil-bearing platform 14, and the telescopic module at the lowermost position is pivotally connected to the hydraulic chamber 09. In this way, the soil-bearing platform 14 and the soil body can be supported by the telescopic support 13 during the movement of the soil-bearing platform 14. Of course, the telescopic module may also include a thick tube and a thin tube. The thick tube is sleeved outside the thin tube, and the thick tube and the thin tube can be telescopically moved in the axial direction of the thick tube.

[0055] Optionally, the telescopic module includes a first support rod 17 and a second support rod 18. The middle of the first support rod 17 is pivotally connected to the middle of the second support rod 18. At the uppermost telescopic module, the top ends of the first support rod 17 and the second support rod 18 are both in sliding fit with the soil-bearing platform 14. At the lowermost telescopic module, the top end of the first support rod 17 and the bottom end of the second support rod 18 are both in sliding fit with the hydraulic chamber 09. For two adjacent telescopic modules, the first support rod 17 of the upper telescopic module is pivotally connected to the second support rod 18 of the lower telescopic module, and the second support rod 18 of the upper telescopic module is pivotally connected to the first support rod 17 of the lower telescopic module. In this way, a telescopic module with high strength and stable telescoping is formed by the two support rods, namely the first support rod 17 and the second support rod 18, and a stronger telescopic support is formed by combining multiple telescopic modules, which can provide relatively stable and reliable support and guidance for the soil-bearing platform 14 and the soil body. In the embodiment of the present application, the fact that the top ends of the first support rod 17 and the second support rod 18 are both in sliding fit with the soil-bearing platform 14 means that a chute with a downward opening is provided on the soil-bearing platform 14, and the top ends of the first support rod 17 and the second support rod 18 both extend into the chute and are in sliding fit with the chute; the fact that the top end of the first support rod 17 and the bottom end of the second support rod 18 are both in sliding fit with the hydraulic chamber 09 means that a chute with an upward opening is provided on the inner wall of the hydraulic chamber 09, and the bottom end of the first support rod 17 and the bottom end of the second support rod 18 both extend into the chute and are in sliding fit with the chute.

[0056] Optionally, the model test tank provided in the embodiment of the present application further includes a support base 12 and a plurality of universal wheels 07. The hydraulic chamber 09 is fixed to the top end of the support base 12, and each universal wheel 07 is fixed to the bottom of the support base 12 of the model test tank. In this way, it is convenient to support the soil body, the tank body 04 and the hydraulic chamber 09, and to move through each universal wheel 07. In the embodiment of the present application, preferably, a plurality of U-shaped grooves 20 are provided at the top end of the support base 12, and the hydraulic chamber 09 is clamped with each U-shaped groove 20 to support the support base 12 through the U-shaped grooves 20.

[0057] Optionally, the model test tank provided by the embodiments of the present application further includes two side movable baffles 01 and a movable backboard 02, both of which are used to be arranged above the tank body 04. A filling port with the same area as the bottom slot opening is provided at the top of the tank body 04. The filling port has a first edge extending in a first direction and a second edge extending in a second direction. One end of the movable backboard 02 is hinged to the second edge, one end of one side movable baffle 01 is hinged to one first edge, and one end of the other side movable baffle 01 is hinged to the other first edge. The two side movable baffles 01 are both detachably connected to the movable backboard 02. In this way, the hydraulic unit can jack up the soil body into the space enclosed by the movable baffles and the movable backboard 02, increasing the height of the slope that can be formed in the model test tank. When it is not necessary to make the height of the slope top higher than the tank body 04, it is only necessary to separate the movable baffles from the movable backboard 02 and rotate and lower the movable baffles and the movable backboard 02 with the hinge position as the axis. The hinge is connected through a hinge 03. In the embodiments of the present application, a diversion groove 08 is further provided at one end of the tank body 04 away from the movable backboard.

[0058] Optionally, the side movable baffle 01, the movable backboard 02, and the tank body 04 are all made of a transparent structure. In this way, it is convenient to observe the soil sample structure layer in the model test tank. The side movable baffle 01, the movable backboard 02, and the tank body 04 can also all use steel pipes or angle irons as frames.

[0059] In the embodiments of the present application, a connection line 10 and a hydraulic system control system 11 provided inside the control terminal are preferably further arranged on the tank body 04, so as to perform automatic control on each hydraulic unit.
