[0049] The test device of the semi-conductive water hose involved in the utility model has the following working principle:

[0050] S1: According to the attached Figure 1-Figure 8 , and the above description of each component to assemble and connect the components;

[0051] S2: When the volume resistivity of the water-blocking tape needs to be measured, such as Figure 4As shown, the operator applies an upward pulling force to the conductive cylinder 13, and the conductive cylinder 13 moves upward in the through hole of the first insulating connection block 15, and the bottom end surface of the conductive cylinder 13 is separated from the top surface of the conductive bottom plate 12; the operator places a water-blocking tape sample with a diameter of 100 mm on the conductive bottom plate 12, and then presses the bottom end surface of the conductive cylinder 13 on the conductive bottom plate 12. The circuit is connected through the control component 5, and a DC power supply is supplied. A closed loop is formed between the conductive cylinder 13, the water-blocking tape, the conductive bottom plate 12, and the control component 5. The voltage measuring instrument and the current measuring instrument in the control component 5 respectively measure the voltage and current of the closed circuit, thereby calculating the resistance and displaying it on the display screen; the resistance is the volume resistivity of the water-blocking tape.

[0052] S3: When it is necessary to measure the surface resistance of the water blocking tape, such as Figure 5 As shown, the operator applies an upward pulling force to the handle 26, and the handle 26 rotates upward around the second insulating connection block 24, and then the connecting rod 27 connected to the handle 26 moves upward, and the connecting rod 27 drives the lifting insulating plate 28 to move upward along the insulating column 25, and the T-shaped electrode 29 fixed on the bottom surface of the lifting insulating plate 28 moves upward and separates from the second bottom plate 21; the operator places a 250mm*250mm water-blocking tape sample on the second bottom plate 21, and then applies downward pressure to the handle 26, so that the lifting insulating plate 28 moves downward and the T-shaped electrode 29 is pressed against the surface of the water-blocking tape. The circuit is connected through the control component 5, and the DC power supply is supplied. A closed loop is formed between the two T-shaped electrodes 29, the surface of the water-blocking tape, and the control component 5. The voltage measuring instrument and the current measuring instrument in the control component 5 respectively measure the voltage and current of the closed circuit, thereby calculating the resistance and displaying it on the display screen; the resistance is the surface resistance of the water-blocking tape.

[0053] S4: When it is necessary to measure the expansion performance of the water blocking tape, such as Figure 6-Figure 7 As shown, the operator cuts the water-blocking tape into a circular test piece with a diameter of 80 mm, then puts the circular test piece into the container 354, and presses the cover plate 353 onto the circular test piece; rotates the loose-leaf 351 so that the infrared tester 352 is directly above the cover plate 353, and resets the infrared tester 352 through the control component 5. Pure water is added to the container 354, and the water contacts the water-blocking tape through the water-permeable holes on the cover plate 353. The water-blocking tape expands and lifts up the cover plate 353. The infrared tester 352 detects the position parameters of the cover plate 353 in real time, and transmits the position of the cover plate 353 to the processor. The processor receives the position parameters of the cover plate 353 and calculates the time when water is added to the container 354, thereby calculating the expansion rate and expansion height of the water-blocking tape and displaying them on the display screen. The expansion rate generally refers to the ratio of the rising height of the cover plate 353 within 1 minute to the time; the expansion height generally refers to the rising height of the cover plate 353 after 5 minutes.

[0054] S5: When it is necessary to measure the pH value of the water blocking tape, such as Figure 8 As shown, first, the infrared tester 352 in step S4 is rotated to the side through the hinge 351, and the cover 353 is taken out from the container 354; then, the mixture containing the circular test piece in the container 354 of step S4 is placed for a period of time and fully stirred, and then the pH tester 362 is placed into the container 354 through the movable bracket 361, and the pH tester 362 is fully in contact with the mixture. The pH tester 362 measures the pH value of the mixture, transmits it to the control component 5, and displays it on the display screen.

[0055] S6: When it is necessary to measure the moisture content of the water-blocking tape, the operator cuts a section of the water-blocking tape and removes the packaging, and immediately weighs it through the weighing device 4, and then the weighing device 4 feeds back the weighing result to the control component 5, so as to obtain the starting weight. The operator puts the section of the water-blocking tape into the oven, and after the required temperature and time are performed according to the standard, the section of the water-blocking tape is taken out of the oven and immediately weighed through the weighing device 4, and then the weighing device 4 feeds back the weighing result to the control component 5, so as to obtain the weight after drying. The processor in the control component 5 obtains the moisture content of the water-blocking tape according to the starting weight and the drying weight, and displays it on the display screen.

[0056] Furthermore, steps S2 to S6 can be performed independently, and it is not necessary to perform step S2 first and then perform subsequent steps S3, S4, S5, and S6.

[0057] The test device for semi-conductive water hose involved in the utility model has the following beneficial effects:
