Technical Field
[0001] The utility model belongs to the technical field of fire protection engineering, and in particular relates to a fire hydrant hose reeling device. Background Art
[0002] Fire protection engineering installation is of great significance in modern buildings and facilities. Fire protection engineering installation can effectively prevent and extinguish fires, reduce the loss of life and property caused by fires. By installing fire alarm systems, fire extinguishing systems and other equipment, fire protection engineering can promptly issue alarms when fires occur and activate fire extinguishing facilities, effectively reducing the harm of fires to people. Fire protection engineering installation helps to improve the public safety of the entire society and ensure the safety of people's lives and property. In fire hydrants, water belts are necessary tools for emergency fire fighting. Usually, the water belts are rolled up and placed in fire hydrants for standby use. At present, most of the water belts are manually operated. Reeling in is physically demanding and time-consuming, and the efficiency is low. When the water belt is in use, there is a lot of water left inside that has not been drained out, and the staff needs to lift the water belt by hand to drain the water inside, which further increases physical energy consumption. After the water belt is used, it is moved from a far distance to a nearby place for easy reeling in. However, the water belt is prone to rotation and twisting during the collection process. If it is directly reeled in, the water belt will be twisted and bent, causing damage. Therefore, it needs to be rotated in the opposite direction when reeling in to make it flat and easy to reel in. However, the operation of rotating the water belt in the opposite direction to flatten the twisted position is more complicated, time-consuming and labor-intensive. Utility Model Content
