[0024] Working Principle: When using this utility model, the operator first connects an external AC power supply to provide power to the electrical appliances within the utility model. Then, the operator connects a computer to the utility model to provide control logic for the operation of the tensioning hydraulic cylinder 5, pressure sensor 4, and high-speed monitoring camera 13. Before starting the utility model, the operator needs to place one end of the fire hose to be tested on the inner wall of the fixed clamping base 6. Then, the operator uses a tool to rotate the fixed clamping screw 7. Under the action of the thread, the fixed clamping screw can be... The lower end of clamp 7 drives the fixed clamping plate 8 downward until the fixed clamping base 6 and the fixed clamping plate 8 fix the fire hose. At this time, the anti-slip pin 15 can firmly fix the fire hose, thereby preventing slippage during the subsequent tensile test. Then, the operator places the other end of the fire hose to be tested on the inner wall of the movable clamping base 9. Then, the operator uses a tool to rotate the movable clamping screw 10. Under the action of the thread, the lower end of the movable clamping screw 10 can drive the movable clamping plate 11 downward until the movable clamping base 9 and the movable clamping plate 11 fix the fire hose. At this time, the anti-slip pin 15 can firmly fix the fire hose, thereby preventing slippage during the subsequent tensile test. This ensures the fire hose is firmly secured, preventing slippage during subsequent tensile testing. The operator then activates the tensile hydraulic cylinder 5 via computer. The cylinder extends, causing the operating base 3 to move linearly along the outside of the two operating rods 2, moving the movable clamping base 9 away from the fixed clamping base 6. Simultaneously, the fire hose is continuously stretched, and the computer records the data from the pressure sensor 4. According to Newton's third law, the data from the pressure sensor 4 represents the tension on the fire hose. The computer not only records the data from the pressure sensor 4 but also records the data over time. The high-speed monitoring camera 13 records the shape of the fire hose in real time, from the start to the end of the test, from when the fire hose is intact to when it breaks. The operator can then compare the external shape of the fire hose with the data obtained by the pressure sensor 4 to obtain more comprehensive tensile test data of the fire hose. A protective glass 14 is installed between the high-speed monitoring camera 13 and the fire hose to prevent the fire hose from breaking and damaging the high-speed monitoring camera 13 when it breaks.
