Description

Technical Field

[0001] The utility model relates to the technical field of geotextiles, in particular to a simulation experimental device for multi-layer anti-clogging geotextiles. Background Art

[0002] The existing geotextile clogging simulation test device and the permeability simulation test device are two devices. The geotextile is usually tested separately by the two devices during the test, resulting in low test efficiency and poor effect.

[0003] For example, a geotextile clogging and permeability simulation experimental device disclosed in Chinese patent publication number CN217277711U, the experimental device is provided with a sprinkler nozzle, the sprinkler nozzle sprinkles water to the geotextile clamped on the clamping mechanism, and the permeability of different geotextiles can be obtained by the amount of water falling to the bottom of the experimental box; by providing a sandblasting tube, the sprinkler nozzle and the sandblasting tube spray water and sand at the same time, the water and sand pass through the isolation net and fall on the surface of the geotextile, so as to test the permeability of the geotextile under clogging conditions. The structure is reasonable, the clogging and permeability experiments are carried out on the same device, the experimental effect is good, and the efficiency is high. By providing a driving motor, a screw rod and a slide groove, the clamping mechanism can be driven to move, a handle is provided on the pressing plate on the clamping mechanism, and the pressing plate is connected to the placement seat by a plug rod and a slot. When the clamping mechanism moves to the top, the pressing plate can be removed by pulling the handle, so as to replace the geotextile, and the geotextile is easy to replace.

[0004] However, it is well known that different types of geotextiles have different lengths and widths, which means that when the experimental length of the geotextile is much longer than the distance between the two sets of clamping mechanisms, the above device must either cut off the excessively long part of the geotextile, or locate the beginning of the geotextile at one end and the end of the geotextile at the other end. The slot at the end is filled with excess geotextile, affecting the positioning and clamping effect. Therefore, the device is not very compatible and adaptable. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a simulation experiment device for multi-layer anti-clogging geotextiles, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions: a simulation experiment device for multi-layer anti-clogging geotextile, including an experiment box body, an experiment cavity is arranged in the experiment box body, a simulation experiment device is arranged inside the experiment cavity, the simulation experiment device includes a geotextile limiting mechanism and a simulation unit, and the simulation mechanism and the geotextile limiting mechanism are both installed on both sides of the inside of the experiment box body;

[0007] The geotextile limiting mechanism is composed of a left limiting unit and a right rolling roller unit, wherein the right rolling roller unit includes a right mounting seat fixedly mounted on the inner wall of the main body of the experimental box, wherein a limiting groove is arranged inside the right mounting seat, wherein an adsorption magnet is fixedly mounted at the limiting groove, wherein the adsorption magnet is semicircular as a whole and its opening faces the left limiting unit, wherein an iron rolling roller is adsorbed inside the adsorption magnet, wherein a geotextile winding recess is fixedly welded to the outer wall of the iron rolling roller, wherein the geotextile winding recess has winding openings symmetrically arranged above and below. The utility model limits the position of one end of the geotextile by passing the initial end of the geotextile into two groups of winding openings arranged in the winding recess, and then gradually wrapping the whole onto the iron rolling roller, and finally the other end of the geotextile is in an unpositioned state on the iron rolling roller, at which time this end of the geotextile is positioned on the left limiting unit, and then the iron rolling roller is gradually rotated to flatten the geotextile and put it in a taut state, and finally the iron rolling roller enters the adsorption magnet and is adsorbed and fixed;

[0008] Therefore, the utility model completes the limitation of the initial end of the geotextile through the left-side limiting unit, and cooperates with the right-side rolling roller unit to complete the overall rolling and storage of the geotextile except the limiting area, and enters the adsorption magnet through the iron rolling roller to complete the overall limiting operation of the geotextile experimental area fabric, so that the device is suitable for geotextiles of different lengths and types, and the geotextile is in a straight state during the simulation experiment, reducing the impact of the stacking or wrinkles of the geotextile on the experimental results.

[0009] The further improvement of the technical solution of the utility model is that: a pressure plate is arranged in the geotextile winding recess, and the pressure plate is connected to the springs arranged in an array on the geotextile winding recess, and one end of each spring is in a fixed connection state with the geotextile winding recess. In particular, when the iron roller enters the geotextile winding recess, the magnetic force is absorbed and because of the special shape of the geotextile winding seat, the magnetic forces on the upper and lower springs are offset by each other, so the spring is finally pulled by the parallel magnetic force and finally drives the pressure plate to complete the fixed limit of the geotextile on the iron roller. When the iron roller is tightening the geotextile, the position of the spring in the adsorption magnet does not make it transverse to the circle, then the position of the iron roller is adjusted by increasing or decreasing the initial end of the geotextile clamped by the left limit unit.

[0010] The further improvement of the technical solution of the utility model is that: the left-side limiting unit includes a left mounting seat fixedly mounted on the inner side wall of the experimental box body, the left mounting seat is provided with a limiting groove, and the left mounting seat is arranged with three groups of threaded positioning screws in an array, the bottom of the three groups of positioning screws are all installed with the same pressing block, the left mounting seat is provided with a geotextile inlet at one end near the right mounting seat, and the bottom of the pressing block is provided with corresponding friction patterns. The corresponding friction patterns are provided to increase the friction between the pressing block and the geotextile, so as to ensure that the left-side limiting unit firmly limits one end of the geotextile.

[0011] A further improvement of the technical solution of the utility model is that: the simulation unit includes a guide slide located below the left mounting seat, the guide slide is slidably connected to a simulation base through a built-in sliding groove and a guide rod installed in a limited position in the sliding groove, a lower guide plate located directly below an upper guide plate is fixedly installed in the simulation base, mounting plates are welded on the right sides of the upper guide plate and the lower guide plate, a striking shaft is rotatably installed on each of the mounting plates, and an array of extrusion rods are welded on each of the striking shafts. The utility model completes the striking and extrusion operation of the geotextile through the extrusion rods located above and below the geotextile to be tested in the simulation unit. Therefore, after the experimenter preliminarily judges the anti-clogging and penetration effects of the silt falling on the geotextile, he can again judge the anti-clogging and other effects of the geotextile under the action of human trampling or natural pressure, and conduct multi-faceted evaluation and judgment on the experimental geotextile, thereby improving the accuracy and diversity of the experimental results.

[0012] A further improvement of the technical solution of the utility model is that each of the striking shafts is keyed to a meshing gear near the right roller unit, and rack seats meshing with the meshing gear are provided at the upper and lower ends of the right mounting seat.

[0013] The further improvement of the technical solution of the utility model is that: an electric push rod is installed on the simulation base through a connector, and the electric push rod is fixedly installed on a bearing seat at the bottom of the experimental chamber. The electric push rod cooperates with the sliding groove and the guide rod installed in the sliding groove to stably move the simulation base horizontally, and the meshing transmission of the meshing gear and the rack seat during the movement completes the rotation of the striking shaft, and finally the upper and lower extrusion rods simulate the striking of the geotextile in the middle during the experiment.

[0014] Beneficial Effects

[0015] The utility model provides a simulation experiment device for multi-layer anti-clogging geotextiles. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The simulation experimental device for multi-layer anti-clogging geotextile completes the limitation of the initial end of the geotextile through the limiting unit on the left, and cooperates with the roller unit on the right to complete the overall rolling and storage of the geotextile except the limiting area, and enters the adsorption magnet through the iron roller to complete the overall limitation operation of the geotextile experimental area, so that the device is suitable for geotextiles of different lengths and types, and the geotextile is in a straight state during the simulation experiment, reducing the impact of the stacking or wrinkles of the geotextile on the experimental results.

[0017] 2. The simulation experimental device for multi-layer anti-siltation geotextile completes the striking and squeezing operation on the geotextile through the squeezing rods located above and below the geotextile to be tested in the simulation unit. Therefore, after the experimenter preliminarily judges the anti-siltation and penetration effect of the silt falling on the geotextile, he can again judge the anti-siltation and other effects of the geotextile under the action of human trampling or natural pressure, and conduct multi-dimensional evaluation and judgment on the experimental geotextile to improve the accuracy and diversity of the experimental results.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides three technical solutions:

[0025] Figure 1-3The first embodiment is shown: a simulation experiment device for a multi-layer anti-clogging geotextile, comprising an experiment box body 1, an experiment cavity is arranged in the experiment box body 1, a simulation experiment device is arranged inside the experiment cavity, the simulation experiment device comprises a geotextile limiting mechanism and a simulation unit, and the simulation mechanism and the geotextile limiting mechanism are both installed on both sides of the inside of the experiment box body 1;

[0026] The geotextile limiting mechanism is composed of a left limiting unit and a right rolling roller unit. The right rolling roller unit includes a right mounting seat 201 fixedly mounted on the inner wall of the experimental box body 1. A limiting groove is arranged inside the right mounting seat 201. An adsorption magnet 202 is fixedly mounted at the limiting groove. The adsorption magnet 202 is semicircular as a whole and its opening faces the left limiting unit. An iron rolling roller 203 is adsorbed inside the adsorption magnet 202. A geotextile winding recess 204 is fixedly welded to the outer wall of the iron rolling roller 203. The geotextile winding recess 204 has winding openings 205 symmetrically arranged above and below. The utility model limits one end of the geotextile by passing the initial end of the geotextile into two groups of winding openings 205 opened in the winding recess 204, and then gradually winding the whole geotextile onto the iron roll 203, and finally the other end of the geotextile is in an unpositioned state on the iron roll 203, at which time the end of the geotextile is positioned on the left limiting unit, and then the iron roll 203 is gradually rotated to flatten the geotextile and put it in a taut state, and finally the iron roll 203 enters the adsorption magnet 202 and is adsorbed and fixed;

[0027] Therefore, the utility model completes the limitation of the initial end of the geotextile through the left-side limiting unit, and cooperates with the right-side rolling roller unit to complete the overall rolling and storage of the geotextile excluding the limiting area, and enters the adsorption magnet 202 through the iron rolling roller 203 to complete the overall limiting operation of the geotextile test area fabric, so that the device is suitable for geotextiles of different lengths and types, and the geotextile is in a straight state during the simulation experiment, reducing the impact of the stacking or wrinkles of the geotextile on the experimental results.

[0028] A pressing plate 206 is provided in the geotextile winding recess 204, and the pressing plate 206 is connected to the springs 207 arranged in an array on the geotextile winding recess 204, and one end of each spring is in a fixed connection state with the geotextile winding recess 204. In particular, when the iron roll 203 enters the geotextile winding recess 204, the magnetic force on the upper and lower springs 207 is offset by each other due to the special shape of the geotextile winding seat 204, so the spring 207 is finally pulled by the parallel magnetic force and finally drives the pressing plate 206 to complete the fixed limit of the geotextile on the iron roll 203. When the iron roll 203 is tightening the geotextile, the position of the spring 207 in the adsorption magnet 202 does not make the spring 207 transverse to the circle, and the position of the iron roll 203 is adjusted by increasing or decreasing the initial end of the geotextile clamped by the left limit unit.

[0029] Figure 1-2The second embodiment is shown, and the main difference from the first embodiment is that the left-side limiting unit includes a left mounting seat 301 fixedly mounted on the inner wall of the experimental box body 1, a limiting groove is set in the left mounting seat 301, and three groups of threaded positioning screws 302 are arranged in an array on the left mounting seat 301, and the bottom of the three groups of positioning screws 302 are all installed with the same pressing block 303, and the left mounting seat 301 is provided with a geotextile inlet 304 at one end close to the right mounting seat 201, and the bottom of the pressing block 303 is provided with corresponding friction lines. The corresponding friction lines are provided to increase the friction between the pressing block 303 and the geotextile, so as to ensure that the left-side limiting unit can stably limit one end of the geotextile.

[0030] Figure 4 A third embodiment is shown, and its main difference from the first embodiment is that the simulation unit includes a guide slide 401 located below the left mounting seat 301, and the guide slide 401 is slidably connected to a simulation base 403 through a built-in sliding groove and a guide rod 402 installed in a limited position in the sliding groove. A lower guide plate 405 located directly below an upper guide plate 404 is fixedly installed in the simulation base 403, and mounting plates 406 are welded on the right sides of the upper guide plate 404 and the lower guide plate 405, and a striking shaft 407 is rotatably installed on each mounting plate 406, and an extrusion rod 408 is welded in an array on each striking shaft 407. The utility model completes the striking and squeezing operation on the geotextile by means of squeezing rods 408 located above and below the geotextile to be tested in the simulation unit. Therefore, after the experimenter preliminarily judges the anti-clogging and penetration effects of the silt falling on the geotextile, he can again judge the anti-clogging and other effects of the geotextile under the action of human trampling or natural pressure, and conduct multi-dimensional evaluation and judgment on the experimental geotextile, thereby improving the accuracy and diversity of the experimental results.

[0031] Each striking shaft 407 is key-connected to a meshing gear 409 near the right roller unit, and rack seats 410 meshing with the meshing gear 409 are provided at the upper and lower ends of the right mounting seat 201 .

[0032] An electric push rod 411 is installed on the simulation base 403 through a connector, and the electric push rod 411 is fixedly installed on a bearing seat at the bottom of the experimental chamber. The electric push rod 411 cooperates with the sliding groove and the guide rod 402 installed in the sliding groove to stably move the simulation base 403 horizontally. During the movement, the meshing gear 409 and the rack seat 410 are meshed and transmitted to complete the rotation of the striking shaft 407. Finally, the upper and lower extrusion rods 408 simulate the striking of the geotextile in the middle during the experiment.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] When in use, insert one end of the geotextile into the geotextile inlet 304, rotate the positioning screw 302 one by one to complete the downward pressing of the pressing block 303, and then the other end enters the two groups of winding openings 205 opened in the winding recess 204, and then the whole is gradually rolled on the iron roller 203, and the geotextile is gradually flattened by rotating the iron roller 203 to the right, and finally the iron roller 203 enters the adsorption magnet 202 and is adsorbed and fixed. At this time, the spring 207 drives the pressure plate 206 to complete the fixed limit of the geotextile on the iron roller 203, and the geotextile is tightened between the two groups of mounting seats. At this time, turn on the water pump above to make the sprinkler spray water, observe the water seepage at the bottom of the geotextile, complete the water seepage experiment, and then pour sand through the pipe. After the water and sand form silt, they are left to stand on the geotextile to observe the anti-siltation performance of the geotextile.
