Description

Technical Field

[0001] The present invention relates to the field of detection of building curtain wall projects, and in particular to a dynamic wind pressure detection system and method for building curtain walls. Background Art

[0002] In coastal typhoon-prone areas, in addition to routine testing of the four properties of building curtain walls, watertightness tests are also required to test the curtain walls' performance under typhoon and heavy rain. Neglecting these tests could lead to serious safety hazards and functional impairments. Therefore, developing a dynamic wind pressure system in the laboratory to simulate natural typhoon and heavy rain conditions is crucial. Research on testing the watertightness of building curtain walls under dynamic wind pressure (referred to as dynamic pressure watertightness) is of great significance. The national standard GB / T 29907-2013 on dynamic pressure watertightness testing for curtain walls stipulates that water is continuously and evenly applied to the outer surface of the specimen at a specified volume to form a continuous water film. Dynamic wind pressure is then applied to the outer surface of the specimen to observe leakage. Dynamic wind pressure is preferably achieved using the propeller method. Currently, there are two types of propeller dynamic pressure air supply systems: one driven by a high-power motor and the other by an aircraft engine. The latter system provides higher dynamic pressure wind speeds, has less impact on the surrounding environment, and has a longer propeller life.

[0003] The existing technology generally has the following problems when performing dynamic wind pressure detection on building curtain walls:

[0004] 1. The propeller engines on the aircraft nose are all old models or retired, and they are noisy when running.

[0005] 2. Due to the different application, the control section of the dynamic pressure air supply system for the aircraft's nose propeller required a redesign. Traditionally, the modified nose dynamic pressure air supply system is manually controlled from a fixed operating room by igniting the ignition and pressing the accelerator to maintain a stable dynamic pressure air velocity. During startup and the entire testing process, the operator must be in the operating room near the back of the aircraft nose. The vibration and noise from the nose directly harm personnel and affect the safety of the system. Furthermore, manually pressing the accelerator to maintain a stable dynamic pressure air velocity results in significant accuracy errors. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems and provide a dynamic wind pressure detection system and method for building curtain walls. The aircraft engine drives the propeller to rotate to provide a wind source. By designing a new type of wind guide tube device and frame structure, as well as a unique operation and control system, a complete set of advanced and practical dynamic wind pressure detection system is formed. The control adopts a remote control method that separates the startup operation control from the engine propeller. The remote control box is used to start and adjust the dynamic pressure wind speed, and maintain it stably to ensure the safety of the operator.
