The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] like Figures 1 to 4As shown, a water testing device for fire protection facility construction includes a mobile frame 1 and a water storage tank 2. A handrail 12 is fixedly installed on one end of the mobile frame 1. A storage box 6 is located on the side of the handrail 12. An airtightness testing pump 7 is located on the side of the storage box 6. An air outlet pipe 8 is connected to the airtightness testing pump 7. A control valve 11 and a pressure gauge 10 are installed on the air outlet pipe 8. An air pipe connection end 9 is located at the end of the air outlet pipe 8. The water storage tank 2 is located on the mobile frame 1 next to the storage box 6. A water pressure testing pump 21 is located on the side of the water storage tank 2, away from the storage box 6. A circulating water pump 3 is installed on one side of the water tank 2, and a filter box 4 is installed on the side of the circulating water pump 3. A water tank fixing shell 18 is installed at the lower part of the water tank 2. A water tank telescopic section 19 is connected to the upper part of the water tank fixing shell 18. A water tank top plate 20 is connected above the water tank telescopic section 19. Multiple support ear plates 15 are partially installed on the outer side of the water tank top plate 20. The bottom surface of the support ear plates 15 is fixedly connected to the telescopic end of the electric telescopic rod 14. The electric telescopic rod 14 is fixedly installed on the mobile frame 1. During the telescopic process of the electric telescopic rod 14, it can drive the water tank telescopic section 19 to extend and retract.

[0024] The water tank telescopic section 19 is sealed to the water tank fixed shell 18. The water tank telescopic section 19 is made of telescopic flexible material. A liquid filling port 16 is provided on the top plate 20 of the water tank. A sealing cover 17 is provided at the liquid filling port 16. The liquid filling port 16 is used to replenish water into the water storage tank 2.

[0025] The inlet of the water pressure test pump 21 is connected to the fixed housing 18 of the water tank via a pipe. A water outlet pipe 22 is provided at the outlet of the water pressure test pump 21. A water pipe connection end 25 is provided at the end of the water outlet pipe 22. A control valve 23 and a pressure gauge 24 are installed on the water outlet pipe 22. The control valve 23 is used to control the water output of the water outlet pipe 22.

[0026] The circulating water pump 3 is connected to the water tank fixed housing 18 through a pipe. The circulating water pump 3 is connected to the filter box 4 through a pipe. The filter box 4 is equipped with a filter circulation inlet 5 for connecting to the discharged water after the test water test, so as to recycle the test water.

[0027] The mobile frame 1 is equipped with casters 13 to facilitate the overall movement of the device.

[0028] The air pipe connection end 9 is sealed to the test pipe through a transition connection pipe, and the water pipe connection end 25 is sealed to the test pipe through a transition connection pipe. The transition connection pipe is a flexible hose to adapt to the test pipe at different height positions.

[0029] The working principle of this utility model is: for the pipeline construction of fire protection facilities, different pipeline inspection methods can be used according to different construction environments;

[0030] Example 1: An airtightness test is conducted on a fire-fighting construction pipeline. A transition connecting pipe is used to seal the air pipe connection end 9 of the airtightness test pump 7 to one end of the pipeline under test. The other ends of the pipeline are sealed. The airtightness test pump 7 is then started, pressurizing the fire-fighting pipeline under test. Pressure gauge 10 displays the pressure status within the pipeline. When the preset pressure range is reached, control valve 11 is closed to maintain the pressure within the pipeline. The changes in pressure gauge 10 during the pressure maintenance process are observed to determine the airtightness of the pipeline under test. If the airtightness of the pipeline is poor, the value of pressure gauge 10 will continuously decrease; if the airtightness of the pipeline is good, the value of pressure gauge 10 will remain relatively stable. After maintaining pressure at one end for a certain period, the changes in pressure gauge 10 after sequentially opening the other ends of the pipeline under test are used to determine the internal connectivity of the pipeline.

[0031] Example 2: When conducting a water test on a fire protection construction pipeline, a transition connection pipe is used to seal the water pipe connection end 25 of the water pressure test pump 21 to one end of the pipeline under test. The other ends of the pipeline under test are sealed. Then, the water pressure test pump 21 is started, and water is pumped from the water storage tank 2 to the pipeline under test. The water pressure in the pipeline under test can be viewed through pressure gauge 24. When the pressure reaches the preset range, control valve 23 is closed to maintain the water pressure in the pipeline. The pressure gauge 24 is observed during the pressure maintenance process. The pressure gauge 24 changes to indicate the sealing performance of the tested pipeline. If the pipeline is not well sealed, the pressure gauge 24 will continuously decrease, indicating leakage. If the pipeline is well sealed, the pressure gauge 24 will remain relatively stable. After holding the pressure at one end for a period of time, the pressure gauge 24 changes by opening the other ends of the tested pipeline in sequence to determine the internal connectivity of the pipeline. When opening the other ends of the tested pipeline, a flexible hose is used to connect to the filter circulation inlet 5 to filter and recycle the test water for repeated use.

[0032] The middle part of the water tank 2 is provided with a water tank telescopic section 19, which can be extended, folded and unfolded under the action of the electric telescopic rod 14, thereby adjusting the capacity of the water tank 2 and making it easy to compress the storage space when not in use. The storage box 6 is used to store connecting hoses, testing tools, etc.

[0033] This utility model has a reasonable structural design and is easy to use. It is equipped with an airtightness test pump 7 and a water pressure test pump 21, which can not only test the airtightness of fire-fighting pipelines, but also conduct water tests on fire-fighting pipelines. It can perform different tests according to different pipeline construction methods to meet diverse usage needs. The water pressure test pump 21 is equipped with a water storage tank 2, a circulating water pump 3 and a filter box 4, which can filter and circulate the water used by the test device, effectively saving water resources. At the same time, the water storage tank 2 has a telescopic structure design, which can adjust the capacity of the water storage tank 2 according to different test needs. When not in use, it can be adjusted to the storage state, effectively reducing the space occupied by the device.
