Description

Technical Field

[0001] The utility model relates to the technical field of foam performance detection in the fire protection industry, in particular to a foldable fire extinguishing foam collection and adhesion performance detection device. Background Art

[0002] Foam properties such as the foaming multiple and 25% liquid extraction time are important parameters that affect the fire extinguishing performance of foam fire extinguishing agents and are also important indicators for evaluating the performance of foam fire extinguishing agents. Generally, during on-site testing of the foam performance of foam fire extinguishing agents and foam generation system equipment, it is generally necessary to use a foam collection device to collect foam for testing foam performance parameters such as the foaming multiple and 25% liquid extraction time. However, existing foam collection devices are large and inconvenient to carry. For example, CN115096648A and CN207515809U disclose a foam collection device; some foam collection devices lack fixed equipment and require personnel wearing rain gear to operate them manually. For example, CN216525649U discloses a portable foam performance testing device.

[0003] Furthermore, in recent years, fires involving solid materials such as photovoltaic equipment and exterior wall insulation materials have become increasingly frequent. The adhesion of foam to combustible surfaces during firefighting is crucial for effectively combating such fires. Currently, foam adhesion is typically tested by measuring the area covered by the foam on a vertical wall. However, this method is relatively simple and unsuitable for evaluating foam adhesion to other materials or at other angles. Consequently, there is a lack of a convenient tool for on-site testing of foam adhesion across a wide range of materials and scenarios.

[0004] Therefore, it is necessary to provide a foldable fire extinguishing foam collection and adhesion performance detection device. Utility Model Content
