Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire water supply, and specifically relates to a fire pressure-boosting and pressure-stabilizing water supply equipment. BACKGROUND

[0002] The fire pressure-boosting and pressure-stabilizing water supply equipment is a new type of equipment using non-toxic capsules as gas-water isolation, which can be used for a long time after one-time inflation. When the fire pressure-boosting and pressure-stabilizing water supply equipment is working, the water supply pump is started, water enters the water chamber, the water pressure rises, the gas in the gas chamber is compressed and the diaphragm is elongated. When the water pressure drops, the gas in the gas chamber expands and the diaphragm contracts, pressing the water chamber to discharge water. This process is repeated. The water pump is controlled to operate by an electric contact pressure gauge and an electric control box to reach the rated pressure and continuous water supply. When a fire alarm occurs and the fire hydrant is opened, the fire-fighting water column is immediately sprayed, and at the same time, the electric contact pressure gauge sends a signal to start the fire pump to supply the required fire water.

[0003] The current fire pressure-boosting and pressure-stabilizing water supply equipment, as described in the patent with the announcement number CN220778911U, includes a bottom plate, the bottom plate is provided with a moving mechanism at the bottom; the moving mechanism includes a fixed plate, the fixed plate is fixed at the left side of the bottom wall of the bottom plate, the fixed plate is provided with a shaft that penetrates and rotates between the two parts, the shaft is provided with wheels at both ends, the shaft is provided with a double-head motor at the middle part, the double-head motor is fixed at the left side of the middle part of the bottom wall of the bottom plate, the right side of the middle part of the bottom wall of the bottom plate is provided with a universal wheel, the universal wheel is provided with a gear at the middle part, the right side of the bottom wall of the bottom plate is fixed with an electric push rod, the output end of the electric push rod is fixed with a toothed plate, and the toothed plate is connected with the gear.

[0004] According to the related technology in the above, the inventor believes that the entire equipment does not have a corresponding anti-freezing structure, and at the same time, water needs to be kept in the fire pipeline at all times to ensure that sufficient water pressure and water volume can be quickly provided in the event of a fire. Therefore, the water in the fire pipeline must always be kept in a water state, which leads to the freezing of the fire water in the entire device in winter when the temperature is low. Once a fire occurs, the entire equipment cannot supply water normally, thereby increasing the risk of further expansion of the disaster area. UTILITY MODEL CONTENTS
