Description

Technical Field

[0001] This utility model relates to the field of fire protection facility testing technology, and in particular to a fire protection partition facility airtightness testing device. Background Technology

[0002] With the continuous development of society and the economy, people's living standards have significantly improved, and their awareness of fire safety has also been continuously enhanced. Fire-resistant partitions, as an important guarantee of fire safety, refer to a series of equipment and devices that can effectively control the fire within a specific space within a certain period of time during a fire, preventing its further spread and diffusion. Although various fire-resistant partitions have different technical requirements in terms of fire resistance stability, structural integrity, and thermal insulation performance, their essential goal of blocking fire sources is the same.

[0003] In the quality inspection of fire-fighting partition facilities, airtightness testing is particularly important. Good airtightness can effectively reduce airflow, thereby slowing the spread of fire, reducing its intensity, and buying valuable time for personnel evacuation and firefighting rescue. However, traditional airtightness testing devices for fire-fighting partition facilities generally test the airtightness of the facilities by negative pressure extraction. Although this method can test the sealing status of the facility's edges, it is not possible to visually observe the test results during the testing process, making it difficult for operators to make quick and accurate judgments. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire-fighting partition facility airtightness testing device. This device immerses the facility under test in a test pool liquid and determines whether the facility's airtightness is up to standard by observing whether bubbles are generated in the liquid. The test results are intuitive and clear, making it easy for operators to make quick and accurate judgments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire-fighting partition facility air tightness testing device includes a testing pool, an internal testing platform, a plurality of fixed plates fixedly installed at the upper end of the testing pool, and a guide rod fixedly installed between the fixed plates and the testing pool. The guide rod passes through the testing platform and is slidably connected to it.

[0007] A bracket is fixedly installed on the upper end of the testing platform, a hydraulic cylinder is fixedly installed on the upper end of the bracket, and a pressure plate is fixedly installed on the telescopic end of the hydraulic cylinder.

[0008] The bottom of the testing pool is equipped with a lifting mechanism for raising and lowering the testing platform.

[0009] The testing platform is equipped with a testing mechanism for facility sealing testing.

[0010] Preferably, the lifting mechanism includes a threaded cylinder fixedly installed at the lower end of the testing platform, a screw connected internally to the threaded cylinder, and a drive motor fixedly installed at the lower end of the testing pool, the drive motor being coaxially fixed with the screw.

[0011] Preferably, the detection platform has multiple through holes adapted to the guide rod, and the guide rod is located inside the through holes.

[0012] Preferably, the testing mechanism includes an airtight groove formed on the upper part of the testing platform, two telescopic pipes connected to the airtight groove are fixedly installed at the lower end of the testing platform, and a connecting pipe is fixedly installed at the other end of the two telescopic pipes. An air pump is fixedly installed on the side wall of the testing pool, and the output end of the air pump is connected to the connecting pipe.

[0013] Preferably, the connecting pipe has a right-angled U-shaped structure and is made of stainless steel.

[0014] Preferably, the upper end of the testing platform is provided with a sealing strip, which is compatible with the airtight groove.

[0015] This utility model has the following beneficial effects:

[0016] By adapting the airtight groove and sealing strip, the fire-fighting partition facility under test is initially sealed and positioned. Then, the hydraulic cylinder drives the pressure plate to firmly press the facility onto the test platform, forming a double sealing measure. This effectively reduces errors caused by poor sealing during the test and improves the accuracy of airtightness testing.

[0017] The method involves immersing the facility under test in a test pool liquid and observing whether bubbles are generated in the liquid to determine whether the facility's airtightness is up to standard. The test results are intuitive and clear, making it easy for operators to make quick and accurate judgments.

[0018] A lifting mechanism is installed, which uses a drive motor to rotate a screw, allowing the testing platform to rise and fall stably along the guide rod. This enables the automatic immersion and removal of the equipment to be tested into the testing pool, reducing the tediousness and labor intensity of manual operation and improving testing efficiency.

[0026] Reference Figures 1-3 A fire-fighting partition facility air tightness testing device includes a testing pool 1, a testing platform 4 is provided inside the testing pool 1, a plurality of fixing plates 5 are fixedly installed on the upper end of the testing pool 1, a guide rod 8 is fixedly installed between the fixing plates 5 and the testing pool 1, the guide rod 8 passes through the testing platform 4 and is slidably connected to it, the testing platform 4 has a plurality of through holes adapted to the guide rod 8, and the guide rod 8 is located inside the through holes;

[0027] A bracket 6 is fixedly installed on the upper end of the testing platform 4, a hydraulic cylinder 7 is fixedly installed on the upper end of the bracket 6, and a pressure plate 9 is fixedly installed on the telescopic end of the hydraulic cylinder 7.

[0028] The bottom of the test pool 1 is provided with a lifting mechanism for lifting the test platform 4. The lifting mechanism includes a threaded cylinder 15 fixedly installed at the lower end of the test platform 4. The threaded cylinder 15 is internally threaded with a screw 14. A drive motor 13 is fixedly installed at the lower end of the test pool 1. The drive motor 13 is coaxially fixed with the screw 14.

[0029] The testing platform 4 is equipped with a testing mechanism for facility sealing testing. The testing mechanism includes an airtight groove 10 opened at the upper end of the testing platform 4. A sealing strip 11 is provided at the upper end of the testing platform 4 and is adapted to the airtight groove 10. Two telescopic pipes 12 connected to the airtight groove 10 are fixedly installed at the lower end of the testing platform 4. A connecting pipe 3 is fixedly installed at the other end of the two telescopic pipes 12. An air pump 2 is fixedly installed on the side wall of the testing pool 1. The output end of the air pump 2 is connected to the connecting pipe 3. The connecting pipe 3 is a right-angled U-shaped structure and is made of stainless steel.

[0030] Working principle:

[0031] The fire compartment is placed on the test platform 4, and the position of the fire compartment to be tested corresponds to the airtight groove 10. The facility is initially sealed and positioned by the sealing strip 11.

[0032] After placement, start hydraulic cylinder 7. The extension and retraction end of hydraulic cylinder 7 drives pressure plate 9 to move downward, firmly pressing the fire-fighting partition facility to be tested onto the test platform 4, ensuring that the facility is stable and well-sealed during the test.

[0033] After fixing, start the drive motor 13. The drive motor 13 drives the screw 14 to rotate. Since the screw 14 is threadedly connected to the threaded cylinder 15, and the test platform 4 is slidably connected to the fixed plate 5 through the guide rod 8 to restrict the rotation, the rotation of the screw 14 will drive the threaded cylinder 15 to move downward, thereby causing the test platform 4 to descend along the guide rod 8 until the device to be tested is completely immersed in the liquid of the test pool 1.

[0034] Subsequently, air pump 2 is started, pumping air into connecting pipe 3. The air then enters the airtight tank 10 through two telescopic pipes 12. If there is a leak in the fire-fighting partition facility under test, the air in the airtight tank 10 will escape from the leak point, generating bubbles in the liquid in the test pool 1. By observing whether bubbles are generated in the liquid in the test pool 1, it can be determined whether the airtightness of the fire-fighting partition facility under test is qualified. After the test is completed, drive motor 13 reverses, driving the test platform 4 to rise and remove the tested facility.
