Description

Technical Field

[0001] The invention relates to the technical field of geotextile detection, in particular to a geotextile fixing device for effective aperture detection. Background Art

[0002] In the process of effective aperture detection of geotextile, the geotextile sample is first cut into a suitable size, generally to be able to completely cover the end face of the test disc, and then the geotextile sample is firmly fixed on the test disc. After the geotextile is fixed, a certain mass of standard granular material is evenly placed on the geotextile, and then the test disc is placed on a vibrating screen for vibration screening. During the screening process, the particles continue to jump and roll on the surface of the geotextile, and the smaller particles gradually fall through the pores of the geotextile. Finally, when the screening is completed, the particles remaining on the geotextile and the particles passing through the geotextile are collected separately, and their mass is weighed using a balance. According to the mass distribution of the particles and the known particle size distribution, the effective aperture of the geotextile is determined by a specific calculation method (such as the O90 method, that is, the particle size when 90% of the particles are blocked by the geotextile).

[0003] In the prior art, when fixing the geotextile, it is necessary to ensure that the surface of the fixed geotextile is flat and wrinkle-free. Therefore, when the geotextile is placed at the port of the detection plate, the detection personnel need to manually smooth the surface of the geotextile first, and then use the clamp to tighten the geotextile. In the process of the detection personnel smoothing the surface of the geotextile, since the geotextile is generally made of fiber material (such as polyester, polypropylene, etc.) and has a soft texture, this softness makes the geotextile, when a wrinkle is pressed by hand, the adjacent part may produce new bending or deformation due to the force, making it difficult to achieve uniform smoothing and wrinkle removal of the geotextile surface. At the same time, in the process of fixing the geotextile with the clamp, it is difficult to control the fixing force of the geotextile, and it is easy to cause excessive pulling of the geotextile due to excessive fixing force, thereby causing the pore size of individual parts of the geotextile to become larger, thereby affecting the accuracy of the geotextile pore size detection. For this reason, we propose a geotextile fixing device for effective pore size detection. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-Figure 8 , a geotextile fixing device for effective aperture detection shown in the figure includes a bottom plate 101 and a detection tube 102 arranged on the bottom plate 101, and also includes a wrinkle removal mechanism arranged on the bottom plate 101 for smoothing and removing wrinkles on the geotextile and a control component arranged on the wrinkle removal mechanism for controlling the tension when the geotextile is fixed;

[0030] The wrinkle removal mechanism comprises a sliding cylinder 201 arranged on the side of the detection cylinder 102 away from the bottom plate 101, a protective component for protecting the standard particles during vibration screening is arranged on the side of the sliding cylinder 201 away from the bottom plate 101, a wrinkle removal ring 203 is fixedly connected to the side wall of the sliding cylinder 201, a plurality of U-shaped plates 204 arranged in a ring array are arranged on the side of the wrinkle removal ring 203 close to the detection cylinder 102, and one end of each U-shaped plate 204 away from the wrinkle removal ring 203 is connected to a wrinkle removal roller 206 through a rotating shaft 205, the bottom plate 101 is provided with a first driving component for driving each wrinkle removal roller 206, and the sliding cylinder 201 is provided with a pressing component for pressing the geotextile;

[0031] It should be noted here that: through the setting of the wrinkle removal component, under the cooperation of the first drive component and the adjustment component, the geotextile can be pulled horizontally and vertically in multiple directions, so that different areas of the geotextile are evenly stressed, thereby realizing the wrinkle removal operation of the geotextile and improving the wrinkle removal effect of the geotextile. At the same time, under the action of the control component, the risk of increasing the pore size of individual parts of the geotextile due to excessive pulling force on the geotextile is reduced, thereby ensuring the accuracy of the geotextile when performing effective pore size detection.

[0032] See also Figure 2 , the control assembly shown in the figure includes a disc-type torque sensor 3 disposed on one side of the U-shaped plate 204, one end of each rotating shaft 205 is disposed through the U-shaped plate 204 and is connected to the disc-type torque sensor 3;

[0033] It should be noted here that: through the setting of the control component, during the rolling process of each wrinkle removal roller 206, when the geotextile is pulled to a certain extent, resistance will be applied to the rolling of the wrinkle removal roller 206, and then the detection function of the disc torque sensor 3 is used to detect the rolling resistance of the wrinkle removal roller 206. When the rolling resistance of the wrinkle removal roller 206 reaches the set threshold, the controller will stop the rotation of the first motor 405, and then stop the rolling and pulling of the geotextile by each wrinkle removal roller 206, thereby reducing the risk of enlarging the pore size of individual parts of the geotextile due to excessive pulling force on the geotextile, thereby improving the accuracy of the geotextile pore size detection;

[0034] It is worth noting that the disc torque sensor 3 is a device specially used to measure the torque of a rotating object. Its basic principle is based on strain gauge technology or magnetoelastic effect. Taking the strain gauge torque sensor as an example, when the rotating shaft 205 is subject to rotational resistance, torsional stress will be generated on the elastic shaft of the sensor. This torsional stress will cause the strain gauge pasted on the shaft to strain, thereby causing the resistance value of the strain gauge to change. The resistance change is then converted into an electrical signal through a Wheatstone bridge circuit. After amplification and processing, the torque value can be obtained, and the torque value is directly related to the rotational resistance.

[0046] It should be noted here that the guide assembly is provided to provide guidance and limiting functions for the movement of the adjustment rod 703 .

[0047] See also Figure 6 The protection assembly shown in the figure includes two second fixed plates 1001 fixedly connected to the side wall of the sliding cylinder 201 and arranged symmetrically with each other, a rotating plate 1003 is connected between the two second fixed plates 1001 through a rotating rod 1002, and a protection plate 1004 is fixedly connected to one end of the rotating plate 1003 away from the rotating rod 1002, and the rotating rod 1002 is provided with a locking assembly for locking the protection plate 1004;

[0048] It should be noted here that: by setting up the protection component, the standard particles on the surface of the geotextile are prevented from overflowing from the sliding cylinder 201 under the action of vibration, so that it is convenient to collect and measure the particles remaining on the geotextile after the test.

[0049] See also Figure 8 , the locking assembly shown in the figure includes a locking plate 1101 fixedly connected to the side wall of one end of the rotating rod 1002, and the locking plate 1101 is threadedly connected with a bolt 1102;

[0050] It should be noted here that: by setting the locking assembly and utilizing the tightening effect of the bolts 1102 on the second fixing plate 1001, the protection plate 1004 is locked, thereby ensuring the stability of the protection plate 1004 during the shielding and protection process.

[0051] Working principle: when testing the effective aperture of the geotextile, first cut a piece of geotextile with a diameter significantly larger than the diameter of the testing tube 102, and then place the cut geotextile at the port of the testing tube 102. After placing the geotextile at the port of the testing tube 102, start the first motor 405 to drive the screw rod 402 to rotate. During the rotation of the screw rod 402, the threaded meshing transmission effect of the screw rod 402 and the driving plate 404 and the guiding effect of the guide rod 403 are used to drive the sliding tube 201 to move close to the testing tube 102.

[0052] When the sliding cylinder 201 moves toward the detection cylinder 102, the wrinkle removal rollers 206 on the U-shaped plates 204 will be synchronously driven to move toward the geotextile. When the wrinkle removal rollers 206 are against the surface of the geotextile and against the end surface of the detection cylinder 102 during the continuous downward movement, the first motor 405 stops moving.

[0053] When each wrinkle removal roller 206 abuts against the end surface of the detection cylinder 102, the third motor 803 is started to drive the rotating gear 802 to rotate, and then the adjusting ring 701 is driven to rotate by the meshing transmission action of the rotating gear 802 and the gear ring 804, thereby synchronously driving the inclined groove 702 on the adjusting ring 701 to rotate, and then under the interaction force between the inclined groove 702 and the adjusting rod 703 and the guiding action of the guide component, each U-shaped plate 204 will be pushed to move away from each other, and then each wrinkle removal roller 206 will be pushed to move away from each other, so that each wrinkle removal roller 206 During the process of moving away from each other, the geotextile is horizontally flattened. When each wrinkle removal roller 206 moves horizontally to the side wall of the detection cylinder 102, the first motor 405 is started again to drive the sliding cylinder 201 to move close to the bottom plate 101, and then drive each wrinkle removal roller 206 to move vertically along the outer side wall of the detection cylinder 102, so as to pull the geotextile vertically in multiple directions. Under the rolling friction of each wrinkle removal roller 206, different areas of the geotextile are evenly stressed, thereby realizing the wrinkle removal operation of the geotextile and improving the wrinkle removal effect of the geotextile.

[0054] In addition, during the rolling process of each wrinkle removal roller 206, when the geotextile is pulled to a certain extent, resistance will be applied to the rolling of the wrinkle removal roller 206, and then the detection function of the disc torque sensor 3 is used to detect the rolling resistance of the wrinkle removal roller 206. When the rolling resistance of the wrinkle removal roller 206 reaches the set threshold, the controller will stop the rotation of the first motor 405, and then stop the rolling and pulling of the geotextile by each wrinkle removal roller 206, thereby reducing the risk of enlarging the pore size of individual parts of the geotextile due to excessive pulling force on the geotextile, thereby improving the accuracy of the geotextile pore size detection;

[0055] After the geotextile is dewrinkled, the second motor 606 is started to drive the first bevel gear 604 at one end of the connecting rod 603 to rotate, so that the threaded rod 602 is driven to rotate under the mutual meshing transmission action of the first bevel gear 604 and the second bevel gear 605, and then the threaded rod 602 is driven to rotate under the threaded meshing transmission action of the threaded rod 602 and the clamping ring 502 and the guiding action of the driving rod 601, so that the clamping ring 502 moves close to the detection cylinder 102, and when the clamping ring 502 and the end faces of the detection cylinder 102 abut against each other, the rotation of the second motor 606 is stopped, so that the abutment action of the clamping ring 502 and the end faces of the detection cylinder 102 is utilized to fix the geotextile on the one hand, and to block the standard particles placed on the surface of the geotextile for effective space detection on the other hand;

[0056] After the geotextile is fixed, the standard particles for testing can be placed on the surface of the geotextile, and then the protective plate 1004 is rotated so that the protective plate 1004 abuts against the end surface of the sliding cylinder 201. After the protective plate 1004 abuts against the end surface of the sliding cylinder 201, the locking assembly is used to lock the protective plate 1004, so as to use the shielding protection of the protective plate 1004 to prevent the standard particles on the surface of the geotextile from overflowing from the sliding cylinder 201 under the action of vibration, so as to facilitate the collection and measurement of the particles remaining on the geotextile after the test.

[0057] After shielding and protecting the port of the sliding cylinder 201, the bottom plate 101 can be connected to the vibrating screen, so that under the vibration of the vibrating screen, the standard particles will continue to jump and roll on the surface of the geotextile, and the smaller particles will gradually fall through the pores of the geotextile. Finally, when the screening is completed, the particles remaining on the geotextile and the particles passing through the geotextile are collected separately, and their masses are weighed using a balance. According to the mass distribution of the particles and the known particle size distribution, the effective pore size of the geotextile is determined by a specific calculation method (such as the O90 method, that is, the particle size when 90% of the particles are blocked by the geotextile).
