Publication number: 20240139564Abstract: A battery pack including fire extinguishing equipment. The fire extinguishing equipment includes a first chamber, a second chamber, and an activation line. The first chamber stores a fire extinguishing chemical agent, the second chamber stores a gas-generating chemical agent, and the activation line extends into the second chamber to be in contact with the gas-generating chemical agent. The second chamber includes a pressure relief opening, and the pressure relief opening is in communication with the first chamber, and is configured to spray the gas in the second chamber to the first chamber. The first chamber includes a discharge opening, and the discharge opening is configured to discharge the fire extinguishing chemical agent in the first chamber after the gas generated after the gas-generating chemical agent is ignited enters the first chamber.Type: ApplicationFiled: January 5, 2024Publication date: May 2, 2024Applicant: Huawei Digital Power Technologies Co., Ltd.Inventors: Zongzhe LIU, Zheng ZHONG, Bin LE, Cheng CHEN, Yezheng ZHANG, Zeshun LIN

Publication number: 20240139565Abstract: The present invention discloses an improved compressed air foam pumping/generation system in which the compressed gas that is used to drive a pumping system is re-utilized and introduced into the outlet manifold to more efficaciously generate a compressed gas foam. A further improvement could include a three-way valve which controls the flow of the compressed gas so that the present invention could be used to generate CAF, aspirated foam (with use of an appropriate nozzle), gels or operate as a simple pump. Additional optional components include a check valve and flexible connection material.Type: ApplicationFiled: October 30, 2022Publication date: May 2, 2024Inventor: Paul C. Ballard

Publication number: 20240139566Abstract: The present invention relates to a novel fire suppression device for prohibiting fire and preventing same from spreading. The device is compact and is configured to autonomously release type A or type B fire-retardant foam for covering a structure such as a building or portions thereof. The device includes a plurality of components, including a water reservoir, a foam concentrate reservoir, an oxygen reservoir, and an aerator for forming fire-retardant foam. In one embodiment, the device includes a sensor for detecting excessive temperature, smoke, or fire for autonomously actuating the device. In another embodiment, the device is manually activated by a user. The device can be used with new or existing buildings, designated fire (i.e., fireplace) spaces, and/or cook areas as well.Type: ApplicationFiled: January 24, 2023Publication date: May 2, 2024Inventor: Christopher Smith

Publication number: 20240139567Abstract: A fire suppression nozzle includes a first support plate, a conduit including an inlet and an outlet, and a baffle made of a porous material extending from the first support plate and at least partially surrounding the outlet to form an interior in fluid communication with the outlet and an end opening. The conduit is configured to receive an inert gas at the inlet and provide the inert gas to the interior of the baffle via the outlet such that the inert gas exits the outlet and passes at least partially through the baffle. The nozzle includes a sound absorbing member extending across the end opening to at least partially enclose the interior, and also includes a sound absorbing insert composed of a sound absorbing material and a second support plate arranged against an outer face of the sound absorbing insert and coupled to the first support plate.Type: ApplicationFiled: December 14, 2023Publication date: May 2, 2024Applicant: Tyco Fire Products LPInventors: Arash Agan, Melissa Ann Figueiredo Loureiro, Michael David Mulzer, Derek M.

Publication number: 20240139568Abstract: Fire protection systems and methods are provided. The system can include a controller communicably coupled with a detector. The controller can receive an input signal from the detector. The detector can be disposed at a location of a space. The input signal can indicate an active hazard event. The controller can determine a speed and a direction of an airflow in the space. The controller can determine an offset for the active hazard event. The offset can be based on at least one of the speed and the direction of the airflow. The controller can provide an actuation command to a sprinkler based on the input signal received from the detector and based on the offset for the active hazard event.Type: ApplicationFiled: March 10, 2022Publication date: May 2, 2024Applicant: Tyco Fire Products LPInventor: Christopher Grayson
