Description

Technical Field

[0001] This utility model belongs to the field of fire hose testing technology, specifically relating to a fire hose explosion resistance testing device. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of a fire hose have metal connectors, allowing connection to another hose to extend the distance or to nozzles to increase the liquid spray pressure.

[0003] The main purpose of burst resistance testing for fire hoses is to assess their pressure-bearing capacity under high-pressure water flow, ensuring they can withstand a certain water pressure without rupturing during actual use, thus guaranteeing the smooth operation of firefighting. However, current burst resistance testing methods have some shortcomings. For example, a fire hose pressure burst resistance testing machine (application number 202322008336.X) uses a servo motor to drive a screw, which in turn drives two pressure plates to fix both ends of the fire hose. This solves the problem of inconvenience for workers installing and disassembling the fire hose during the test, thus reducing testing efficiency. However, burst testing requires a significant increase in water pressure inside the fire hose, while the positive pressure provided by the servo motor-driven screw is relatively small. The relationship between the thread torque and pressure is: Pressure = 3.14 x Torque. Torque / pitch: Common servo motor torque ranges from 0.5Nm to 10Nm. Servo motors requiring locking torque need to reach 20Nm to 35Nm. Therefore, in this solution, to achieve the fixing effect of a fire hose burst test, a high-priced servo motor is needed. Furthermore, servo motors are not very waterproof, and water will splash during the test. Therefore, the servo motor also needs to meet certain waterproof requirements. As a result, servo motors that meet both high torque and waterproof requirements are very expensive, thus increasing the overall price of the equipment and impacting its subsequent sales and promotion.

[0011] The fire hose burst resistance testing device of this utility model has the following advantages compared with the prior art:

[0012] 1. This fire hose burst resistance testing device uses a hydraulic system to fix both ends of the fire hose. The hydraulic fixing ensures the positive pressure at both ends of the fire hose, thus preventing the ends of the fire hose from falling off during the test. It also increases the installation speed of the fire hose, thereby improving the efficiency of the burst test.

During the fire hose burst test, a large amount of water will splash and get on the hydraulic system. However, this will not have a significant impact on the hydraulic system and will not affect the normal conduct of the fire hose burst resistance test. Attached Figure Description

[0024] Working principle:

[0025] I. Equipment Installation: Before using this utility model, an external AC power supply needs to be connected to this utility model to provide energy for the electrical appliances in this utility model. Then, the computer and the matching controller are connected to the booster pump 6, water pressure sensor 10, clamping hydraulic device 12 and high-speed camera 19 in this utility model to provide them with working logic. Finally, the operator introduces the water source for testing into the water tank body 15 to provide water source for subsequent tests.

[0026] II. Testing: The operator opens the transparent protective cover 17 and takes a section of fire hose to be tested. Both ends of the fire hose are respectively fitted onto the outside of the booster pipe 3 and the pressure testing pipe 8. At this time, the operator drives the clamping hydraulic device 12 through the controller. The clamping hydraulic device 12 extends, causing the clamping plates 13 to move towards the booster pipe 3 and the pressure testing pipe 8 until one end of the fire hose is fixed by the two clamping plates 13 and the booster pipe 3, and the other end is fixed by the two clamping plates 13 and the pressure testing pipe 8. The operator then fastens the transparent protective cover 17 back onto the transparent protective outer shell 16. Then the operator... The test is initiated, at which point the booster pump 6 starts working. The booster pump 6 draws water from inside the water tank 15 through the water supply pipe 4 and the one-way valve 5 into the fire hose. The booster pump 6 continues to work, causing the water pressure inside the fire hose to rise continuously. At this time, the water pressure sensor 10 records the water pressure inside the fire hose and stores the water pressure information in the computer. The high-speed camera 19 records the outside of the fire hose until the fire hose bursts. At this time, the water pressure sensor 10 detects that the water pressure has returned to zero, the booster pump 6 stops working, and the water inside the fire hose flows back to the water tank 15 through the return pipe 18, completing the test.

[0027] III. Data Processing: After the test is completed, the external information of the fire hose from the high-speed camera 19 from its intact state to the state after the burst is obtained, and the water pressure sensor 10 can obtain the internal water pressure of the fire hose from the start of the test to the state after the burst. The operator can combine these two sets of data to conduct burst test analysis on the fire hose, thereby guiding the subsequent processing and upgrading of the fire hose.
