Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing and explosion suppression testing technology, and in particular to a pressure-resistant chamber for collecting data in fire extinguishing and explosion suppression tests. Background Technology

[0002] In the field of industrial safety, research on fire suppression and explosion extinguishing technologies is of great significance for ensuring production safety and reducing the hazards of explosion accidents. Fire suppression and explosion extinguishing tests, as a crucial step in the research and verification of this technology, require accurate acquisition of experimental data to deeply analyze the internal mechanisms of explosions and the fire suppression and explosion extinguishing processes. The pressure-resistant data acquisition chamber used for such tests becomes the core equipment determining the success or failure of the test.

[0003] Currently, six-sided cubic pressure chambers are widely used in fire suppression and explosion extinguishing tests in China. These chambers, with their stable structure, can withstand the high pressure generated during an explosion, providing a relatively safe and enclosed environment for the test. However, with technological advancements and increasingly complex testing requirements, existing chambers have revealed numerous shortcomings in data acquisition.

[0004] From the perspective of data acquisition device installation, various data acquisition devices, such as pressure sensors, temperature sensors, and high-speed cameras, are mainly installed on the cabin body by welding or bolting. This installation method lacks versatility. Whenever test requirements change and data acquisition devices need to be added or replaced temporarily, complex operations such as drilling, welding, or re-bolting must be performed on-site. This not only consumes a lot of manpower and time but also requires extremely high professional skills from technicians. Even slight carelessness can lead to displacement or damage of the data acquisition devices during the test due to installation position deviations or insecure fixing, thus seriously affecting the accuracy and reliability of data acquisition.

[0005] During the test preparation phase, the entire process was cumbersome and lengthy due to the limitations of the cabin structure. Before each test, technicians had to transport all the necessary data acquisition devices to the site according to the test plan, and then fix them onto the cabin one by one according to specific installation methods. During installation, the position and angle of the devices needed to be constantly fine-tuned to meet the data acquisition requirements. After installation, all data acquisition devices needed to be fully debugged, including measurement range calibration, parameter setting, and data transmission stability checks. For example, high-speed cameras required fine adjustments to the shooting angle, frame rate, and resolution, and pressure sensors needed repeated verification of measurement accuracy. Problems in any of these steps could lead to test delays. In addition, the interior of the cabin needed to be thoroughly cleaned before and after the test to ensure that the test environment was free from impurities, which undoubtedly further increased the test preparation time and workload. Utility Model Content

[0006] The purpose of this invention is to provide a pressure-resistant chamber for collecting data from fire extinguishing and explosion suppression tests. By using this device, the above-mentioned problems can be solved.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pressure-resistant chamber for collecting data from fire extinguishing and explosion suppression tests, comprising a pressure-resistant chamber body, a projectile launch point, and a projectile release point. The projectile launch point is provided at the front end of the pressure-resistant chamber body, cable channels are provided on the top and sides of the pressure-resistant chamber body, an exhaust assembly is provided at the rear end of the left side of the pressure-resistant chamber body, an explosion-proof door is installed at the front end of the left side of the pressure-resistant chamber body, a kerosene pipeline assembly is provided on the top of the pressure-resistant chamber body, a projectile release point is provided at the rear end of the pressure-resistant chamber body, a camera detection port is provided on the right side of the pressure-resistant chamber body, and a data acquisition assembly is provided inside the pressure-resistant chamber body.

[0008] Preferably, the data acquisition components include a pressure detection module installed at the front end of the pressure chamber body, fire extinguishing bottles installed at the rear ends of both sides of the pressure chamber body, a gas composition detection module installed at one end of the fire extinguishing bottle, and a detector installed at the top of the pressure chamber body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model provides a pressure-resistant chamber for data acquisition in fire extinguishing and explosion suppression tests. The structural components related to the launch and discharge points are easily replaceable after each test, requiring no complex operations and significantly shortening maintenance time between tests. Simultaneously, various data acquisition devices can be quickly installed and replaced using a universal adapter plate, adapting to different equipment models without requiring additional modifications to the chamber due to device changes. This greatly simplifies the preparation work for data acquisition devices before and after tests, significantly improves overall testing efficiency, allows for more tests to be completed per unit time, and accelerates the research progress of fire extinguishing and explosion suppression technology.

[0011] 2. This utility model provides a pressure-resistant chamber for collecting data in fire extinguishing and explosion suppression tests. The chamber uses a pressure relief plate for depressurization, which, compared to traditional depressurization methods, can release pressure more quickly when the internal pressure rises sharply during the test. This effectively avoids the chamber being subjected to excessive pressure impact, reduces the risk of deformation and damage due to pressure overload, greatly extends the service life of the chamber, ensures the stability and safety of the chamber structure during multiple tests, and provides a solid and reliable hardware foundation for the continuous conduct of tests.

[0012] 3. This utility model provides a pressure-resistant chamber for data acquisition in fire extinguishing and explosion suppression tests. This chamber serves as a protective outer shell for all data acquisition devices within the chamber, effectively resisting various interference factors in the test environment, such as electromagnetic interference and shock wave interference. It prevents data acquisition devices from malfunctioning or showing data deviation due to external interference, ensuring that the acquired data accurately reflects the changes in various parameters during the fire extinguishing and explosion suppression test. This provides reliable data support for subsequent analysis and research of the test results, facilitating a deeper and more precise exploration of the fire extinguishing and explosion suppression mechanism.
