Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting and fire extinguishing, in particular to a water supply device for fire fighting and fire extinguishing. Background Art

[0002] With the continuous acceleration of urbanization and the increasing number of various types of buildings, the risk of fire is also increasing. Modern buildings have complex structures and diverse functions, and are often densely populated with people and materials. Once a fire occurs, the consequences are unimaginable. This puts higher demands on the fire-fighting system, and reliable water supply equipment is a key component of the fire-fighting system.

[0003] Existing technologies include the utility model with publication number CN209907490U, which discloses an intelligent fire-fighting constant-pressure water supply device. The patent adopts a buffer tank, a booster water pump, a water supply mechanism and an electrical cabinet. The buffer tank, the booster water pump, the water supply mechanism and the electrical cabinet are all installed on the surface of the base, and a number of rollers are installed at the bottom of the base. An inlet pipe is provided at the top of the buffer tank, and an outlet pipe is provided on the bottom side wall of the buffer tank. The outlet pipe is connected to the booster water pump through a pipe. A winding rack is provided inside the water supply mechanism, and a support frame is installed at the bottom end of the winding rack. By arranging a water supply mechanism on the base, the water pipe inside the water supply mechanism is a hose, which is wound around the winding column inside the water supply mechanism when not in use. When in use, the hose is pulled apart so that the water nozzle can be close to the fire source for fire extinguishing. After use, the hose is rewound around the outer wall of the winding column through the rocker. This makes it convenient to organize the water pipes after the fire is extinguished, and improves efficiency. It solves the problem that the intelligent fire-fighting constant-pressure water supply device needs to be manually connected to the water pipe for water supply, which is inefficient and inconvenient to use, and the booster water pump used for constant pressure generates a lot of noise when working. An intelligent fire-fighting constant-pressure water supply device is provided, which has the advantages of shock absorption and noise reduction, reduces manpower when supplying water, and improves efficiency.

[0004] In the process of using fire-fighting water supply equipment to extinguish fires in daily life, the fire-fighting water supply equipment may generate vibration during operation. Long-term vibration may cause the internal parts of the equipment to loosen, wear or even be damaged. The vibration may also be transmitted to the pipes connected to the water supply equipment, causing stress concentration and fatigue damage to the pipes, resulting in a shortened life of the fire-fighting water supply equipment and the inability to stably deliver fire water. Utility Model Content

A fire-fighting water supply equipment is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fire-fighting water supply equipment, comprising a base, a buffer tank and a shock-absorbing assembly, wherein the buffer tank is mounted on the upper surface of the base, an electrical cabinet is mounted on the upper surface of the base, a shock-absorbing assembly is mounted on the lower surface of the base, a booster water pump is mounted on the upper surface of the shock-absorbing assembly, a horizontal plate is fixedly connected to the lower surface of the horizontal plate, a pulley is mounted on the lower surface of the horizontal plate, the shock-absorbing assembly comprises a rubber pad, the lower surface of the booster water pump is fixedly connected to the rubber pad, the lower surface of the rubber pad is fixedly connected to a steel plate, the upper surface of the horizontal plate The surface is fixedly connected to a limit block, a circular hole is opened on the surface of the limit block, the limit block is located on the inner wall of the circular hole and is slidably connected to a guide rod, the surface of the limit block is fixedly connected to a buffer spring, the side surface of the limit block is fixedly connected to a linkage rod, the side surface of the limit block is fixedly connected to a deceleration spring, the end of the deceleration spring away from the limit block is fixedly connected to a damping sleeve, the upper surface of the damping sleeve is fixedly connected to a first linkage block, the lower surface of the steel plate is fixedly connected to a fixed block, the side surface of the fixed block is fixedly connected to a second linkage block, and the surface of the second linkage block is rotatably connected to a connecting arm.

[0007] Preferably, the steel plate is fixedly connected to the surface of the guide rod, the steel plate is fixedly connected to the lower surface of the base, and the length of the steel plate is flush with that of the base.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, by setting a shock-absorbing component, when a fire occurs and it is necessary to extinguish the fire, the fire water supply equipment is pushed to drive the pulley to slide on the ground. When approaching the fire scene, the electrical box, the booster water pump and the buffer tank are connected through the water pipe, and the spray is aimed at the lower end of the fire. When the booster water pump is working, a part of the shock force is absorbed by the rubber pad, and the remaining shock force is weakened by cooperating with the steel plate.

The buffer spring is squeezed and deformed, thereby driving the guide rod and the fixed block to slide downward, and at the same time the connecting arm is Under the action of the fixed block, it moves to both ends and opens, and then drives the damping sleeve. The damping sleeve slowly approaches the limit block, and the deceleration spring is deformed under the force. While deforming, the vibration of the booster pump is weakened to a minimum. When the fire becomes smaller and no boosting is needed, the booster pump can be turned off. By setting a shock-absorbing component, the vibration energy can be effectively absorbed and reduced when the equipment is working, and the mechanical damage to the equipment due to vibration can be reduced. At the same time, the impact of vibration on the pipeline can be reduced, and the risk of pipeline rupture can be reduced, further improving the service life of the equipment and the stability of fire water delivery.

[0023] The top surface of the second support frame 71 is fixed with a first link 79, and the bottom surface of the second support frame 71 is fixed with a first link 79.

[0024] Specifically, the steel plate 72 is fixedly connected to the surface of the guide rod 73 , and the steel plate 72 is fixedly connected to the lower surface of the base 1 , and the length of the steel plate 72 is flush with that of the base 1 .

[0025] The effect achieved by the above components is that the force generated by the booster water pump 4 is partially absorbed through the cooperation between the steel plate 72 and the rubber pad 71 .

[0026] Specifically, the guide rod 73 passes through the limit block 74 , passes through the transverse plate 5 , is located in the middle of the buffer spring 75 , and is two in number. The two guide rods 73 are symmetrically arranged about the steel plate 72 .

[0027] The effect achieved by the above components is that the vibration speed of the steel plate 72 can be buffered through the cooperation between the guide rod 73 and the buffer spring 75.

[0028] Specifically, there are two limit blocks 74 , and the two limit blocks 74 are disposed symmetrically about the linkage rod 76 .

[0029] The effect achieved by the above components is: through the limit block 74, the positions of the buffer spring 75, the linkage rod 76 and the deceleration spring 77 can be supported.

[0030] Specifically, the linkage rod 76 is disposed inside the deceleration spring 77 , the linkage rod 76 is disposed inside the damping sleeve 78 , and the linkage rod 76 is disposed just below the fixing block 710 .

[0031] The effect achieved by the above components is that, through the cooperation between the linkage rod 76 and the damping sleeve 78 , the vibration force of the booster water pump 4 can be double-buffered.

[0032] Specifically, there are two first linkage blocks 79 , and the two first linkage blocks 79 are disposed symmetrically with respect to the fixed block 710 .

When approaching the fire scene, connect the electrical box, the booster pump 4 and the buffer tank 2 through the water pipe, and spray at the bottom of the fire. When the booster pump 4 is working, it absorbs part of the shock force through the rubber pad 71, and cooperates with the steel plate 72 to weaken the remaining shock force. The steel plate 72 vibrates downward and transmits the force to the buffer spring 75 and the guide rod 73. The buffer spring 75 is squeezed and deformed, thereby driving the guide rod 73 and the fixed block 710 to slide downward. At the same time, the connecting arm 712 is fixed Under the action of the fixed block 710, it moves to both ends and opens, and then drives the damping sleeve 78, which slowly approaches the limit block 74. The deceleration spring 77 is deformed by the force, and at the same time, the vibration of the booster pump 4 is weakened to a minimum. When the fire becomes smaller and no boosting is needed, the booster pump 4 can be turned off. By setting the shock-absorbing component 7, the vibration energy can be effectively absorbed and reduced when the equipment is working, and the mechanical damage to the equipment due to vibration can be reduced. At the same time, the impact of vibration on the pipeline can be reduced, and the risk of pipeline rupture can be reduced, further improving the service life of the equipment and the stability of fire water transportation.
