A sample of a certain size is intercepted, and the measuring head of the thickness gauge automatically descends onto the sample. The thickness value of the sample is measured under a fixed pressure and a fixed contact area, strictly meeting the standard requirements, effectively ensuring the standardization and accuracy of the test.

[0003] Publication No. CN 212179858 U discloses a geotextile thickness gauge. First, the geotextile is placed on the reference plate, then the pressure foot is manually placed on the geotextile and the upper end of the pressure foot is made to contact the pointer of the instrument. Then the eccentric wheel is rotated so that the eccentric wheel does not contact the balance rod. Subsequently, weights are added to the weight pan to make the balance rod squeeze the pressure foot, and the measurement data is displayed on the instrument. It is necessary to manually lift the horizontal rod to place the measurement object, with low measurement accuracy, a complicated measurement process, and it is easy to be damaged and not suitable for long-term use. To solve the above deficiencies, the utility model provides a double-station geomembrane thickness gauge. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] As Figure 1-2 shown, a double-station geomembrane thickness gauge includes a housing 1, and the housing 1 includes a base 2 and an upper housing 3. A fixing table 5 is arranged above the base 2 through a plurality of fixing rods 4. A weight pressing device 6 and a fixing frame 7 are fixedly arranged on the fixing table 5. A displacement sensor 8 is arranged directly above the weight pressing device 6, and a reference seat 9 is arranged directly below the weight pressing device 6. The reference seat 9 is fixedly arranged on the base 2. A numerical control panel 10 is embedded and installed on the surface of the upper housing 3;

[0022] The weight pressing device 6 includes a lower pressing rod 11 and a pressing block 12. Weights are placed on the pressing block 12 according to different needs. The top of the lower pressing rod 11 is in contact with a rotating rod 14 through a hole groove 13. The rotating arm 15 includes a first rotating arm 151 and a second rotating arm 152. The rotating rod 14 is fixedly connected to the first rotating arm 15. The first rotating arm 151 is connected to a fixing block 16 through round shafts at both ends. Counterweight blocks 17 are arranged on both sides of the second rotating arm 152;

[0023] A fixing side plate 18 is arranged on the fixing table 5. A rotating motor 19 is arranged on the fixing side plate 18. The rotating motor 19 is connected to a rotating and resetting pressing plate 20 through a shaft. When the rotating and resetting pressing plate 20 rotates, it can drive the first rotating arm 151 to press down and rotate and the second rotating arm to rotate, so that the rotating rod 14 is lifted upward and the lower pressing rod 11 is lifted and reset.

[0024] Furthermore, an information transmission device 21 is also arranged on the fixing table 7. The information transmission device 21 is electrically connected to the displacement sensor 8, the numerical control panel 10 and the rotating motor 19, and is remotely transmitted to the cloud through the information transmission device, which is convenient for storing the thickness data of the geomembrane. The terminal owner can also view the thickness data of the geomembrane in a timely manner.

[0025] Furthermore, two weight pressing devices 6 are symmetrically arranged on the fixing table 5 to improve work efficiency and can measure the thicknesses of two geomembranes simultaneously.

[0026] Furthermore, the displacement sensor 8 adopts a serial port grating micrometer displacement sensor, which has high test accuracy, and the test accuracy can reach 0.001 mm.

[0027] Furthermore, feet 22 are installed at the four corners of the bottom end of the base 2, and an anti-slip pad is installed on the bottom end surface of the feet 22. By setting an anti-slip pad at the bottom of the feet, the overall stability can be increased.

[0028] Further, the displacement sensor 8 includes a measuring part 81 and a clamping part 82. The measuring part 81 and the clamping part 82 are connected by threads. The clamping part can fix the displacement sensor on the fixing frame, and its interior is fixed up and down by threads, which is convenient for assembly and disassembly.

[0029] The working process of the present utility model is as follows:

[0030] Before the test, the rotation motor is controlled to rotate through the control panel, so that the rotation reset pressing plate rotates. Due to the structure of the rotation reset pressing plate adopting a concave-convex heart-shaped structure, the rotation reset pressing plate can press down the first rotating arm. Counterweights are also arranged on both sides of the first rotating arm. Therefore, the first rotating arm can easily press down and drive the second rotating arm to rotate. The second rotating arm is fixedly connected to the rotating rod. Thus, the rotating rod rotates upward under the drive of the second rotating arm. The rotating rod is arranged in the groove at the top of the pressing rod and contacts it. Therefore, the pressing rod also moves upward. Finally, the pressing rod drives the pressing block to move upward.

[0031] After the rotation of the rotation motor and the transmission between the structures, there is a certain distance between the pressing block and the reference seat. At this time, the specimen of the geotextile is placed on the reference seat. The control panel controls the rotation motor to rotate again. Similar to the above movement structure, the pressing block contacts the reference seat again. Subsequently, one or more weights are pressed on the pressing block. The thickness value of the geomembrane is obtained by measuring the distance from the distance sensor to the top of the pressing rod and the distance to the top of the pressing rod in the initial state, and is displayed on the operation panel. At the same time, it is remotely transmitted to the cloud through the information transmission device, which is convenient for storing the thickness data of the geomembrane. The terminal owner can also view the thickness data of the geomembrane in time.
