Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting water pipe storage, and in particular relates to a fire-fighting water pipe storage device. Background Art

[0002] In modern society, people's living standards are getting higher and higher, and people's attention to safety is also getting higher and higher. At the same time, the development of various technologies and industries has made fires more and more likely to occur. After a fire occurs, firefighters need to rush to the scene quickly, pull out the fire hose and connect it to the water tank of the fire truck to extinguish the fire. After the fire is extinguished, the water hose needs to be rolled up. At present, the fire hose is generally folded and coiled manually, but because the fire hose is heavy and long, it is not easy to store it manually. At the same time, there may be water left inside the fire hose after use. Manual storage may not be able to tightly roll up the water hose, and the water hose may be detached.

[0003] Patent authorization number CN218572692U discloses a fire cabinet that is easy to store fire hoses. The residual water in the hose is squeezed out by two squeezing rollers, and then the hose is limited and protected by springs and conduit racks to improve the compactness of the hose storage. However, the spring is in a power storage state for a long time and is prone to elastic fatigue. Once the spring fails, it can no longer provide a limit. In addition, the elastic force of the spring is limited. After the hose is rolled up in multiple layers, it will tend to rebound outward. The elastic force of the spring alone cannot provide a stable storage effect for the hose. Moreover, there is generally a large amount of dense fog at the fire scene. The hose will inevitably be contaminated with smoke and dust when spraying water for fire fighting, and the hose needs to be cleaned before storage. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a fire water pipe storage device, which is convenient for tightly rolling up the water pipe and can automatically discharge excess water in the water pipe before rolling up, while achieving the effect of cleaning the water pipe. The device has a simple structure and good practicality.

[0005] The solution adopted by the utility model to solve the technical problem is: a fire hose storage device, including a storage rack consisting of a left frame and a right frame, and also including a linkage control mechanism and a spraying assembly, the middle rotation sleeve of the storage rack is provided with a main shaft, the main shaft is fixedly provided with a winding roller, a pressure rod is arranged in parallel around the winding roller on the storage rack, the linkage control mechanism includes a screw rod symmetrically installed in the storage rack, and the screw rod is vertically arranged with the pressure rod, a nut is threadedly sleeved on the screw, and a movable groove matching the two ends of the pressure rod is opened on the inner side of the storage rack, and the two ends of the pressure rod penetrate The gear is fixedly mounted on the drive shaft and is engaged with the nut and is in a movable groove. Main bevel gears are fixedly mounted on both ends of the main shaft, and a slave bevel gear meshing with the main bevel gear is fixedly mounted on the inner end of the screw. The rotation of the main shaft can synchronously drive the screw to rotate through the meshing of the main bevel gear and the slave bevel gear. The increased thickness of the winding roller when winding the water pipe is consistent with the moving height of the nut. The spray washing assembly includes a mounting platform fixed above the front sides of the left and right frames, and a spray pipe is installed on the mounting platform. The spray pipe is located in the middle of the storage rack, and the nozzle corresponds to the front side of the pressure rod, and the water inlet end of the spray pipe is connected to the water inlet pipe.

[0006] Furthermore, there are multiple groups of pressure rods and screw rods, and they are evenly distributed around the winding roller.

[0007] Furthermore, a push handle is provided at the upper end of the storage rack, a handle is fixed at the front end of the push handle, and moving wheels are installed at the lower end of the storage rack.

[0008] Furthermore, a hand-cranked transmission assembly is provided on the outer side of the storage rack, and the hand-cranked transmission assembly includes auxiliary rotating shafts installed at the upper and lower ends of the push handle, and one end of the two auxiliary rotating shafts and the main rotating shaft are fixedly mounted with pulleys, and the adjacent auxiliary rotating shafts and the main rotating shaft are connected by belt one and belt two.

[0009] Furthermore, the pressure rod may be a roller, and both ends of the roller are rotatably mounted on corresponding nuts.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] See also Figure 1-4 The utility model provides a technical solution for a fire hose storage device: Example

[0019] according to Figure 1 and Figure 2 As shown, the storage rack 1 comprises a left frame body and a right frame body, a main rotating shaft 2 is rotatably mounted on the center of the storage rack 1, a winding roller 3 is fixedly mounted on the main rotating shaft 2, and the winding roller 3 is located in the middle position of the storage rack 1. By controlling the rotation of the main rotating shaft 2, the winding roller 3 can be driven to rotate to wind up the fire water pipe; a plurality of pressure rods 5 are arranged in parallel around the winding roller 3 on the storage rack 1, and a linkage control mechanism 4 is also arranged on the storage rack 1 for driving the pressure rod 5 to make adaptive and autonomous adjustments following the winding process of the water pipe, and the pressure rod 5 can provide a limit in the process of winding the water pipe, so that the water pipe can be stored in a tight state.

[0020] according to Figure 3 and Figure 4As shown, the linkage control mechanism 4 includes screw rods 42 symmetrically installed in the storage rack 1. The number of screw rods 42 is consistent with that of the pressure rod 5 and the screw rods 42 are arranged vertically to the pressure rod 5. Here, three are taken as an example. The three pressure rods 5 are evenly distributed on the circumference of the winding roller 3. Three screw rods 42 are rotatably mounted at positions vertically corresponding to the pressure rod 5 in the storage rack 1. Nuts 44 are threadedly mounted on the screw rods 42. Active grooves 45 matching the two ends of the pressure rod 5 are opened on the inner side of the storage rack 1. The two ends of the pressure rod 5 pass through the active grooves 45 and are connected to the nuts 44. Main bevel gears 41 are fixedly mounted on the two ends of the main shaft 2, and the screw rods 42 are provided on the inner side of the storage rack 1. The inner end portion of 42 is fixedly sleeved with a slave bevel gear 43 meshing with the main bevel gear 41; in the process of rotating and winding the water pipe, the main rotating shaft 2 can synchronously drive each screw 42 to rotate through the meshing transmission action of the main bevel gear 41 and the slave bevel gear 43, and under the thread cooperation of the screw 42 and the nut 44, the pressure rod 5 can be synchronously controlled to move upward, and the increased thickness of the water pipe after winding one circle on the winding roller 3 matches the height of the movement of the nut 44, that is, the pressure rod 5 can make adaptive position adjustment according to the thickness of the winding water pipe to ensure that the pressure rod 5 can always be pressed tightly against the surface of the outermost circle of the water pipe, providing a tight storage effect for the water pipe.

[0021] When the winding roller 3 is winding the fire water pipe, the fire water pipe will first be squeezed by a pressure rod 5. Since the pressure rod 5 squeezes the water pipe tightly, the residual water in the fire water pipe will be squeezed out through the pressure rod 5 before winding, thereby realizing the automatic discharge of the residual water in the water pipe.

[0022] A push handle 7 is installed obliquely at the upper end of the storage rack 1, and a handle 9 is fixed to the front end of the push handle 7. A moving wheel 10 is installed at the lower end of the storage rack 1. During the process of reeling in the fire hose, the device can be stopped at a designated position to allow the hose to be moved and reeled. Since the fire hose is long and heavy and not easy to move, firefighters can also push the device forward through the moving wheel 10. The device reels the hose while moving, so that the hose does not need to be moved, thereby reducing the workload when storing the fire hose.

[0023] A hand-cranked transmission assembly 6 for controlling the rotation of the main rotating shaft 2 is arranged on the outer side of the storage rack 1, and the hand-cranked transmission assembly 6 includes auxiliary rotating shafts 61 installed at the upper and lower ends of the push handle 7, and pulleys are fixedly mounted on one end of the two auxiliary rotating shafts 61 and the main rotating shaft 2, and the lower auxiliary rotating shaft 61 and the lower auxiliary rotating shaft 61 are connected by belt 2 63, and a turning handle 64 is fixedly mounted on the upper auxiliary rotating shaft 61. When storing water pipes, firefighters can push the device to move while turning the turning handle 64, and the main rotating shaft 2 is driven by the transmission of the belt to reel in the fire water pipe. By setting two belts, firefighters do not need to bend over to control the rotation of the main rotating shaft 2 when storing the water pipes, thereby improving the convenience of use; the main rotating shaft 2 can also be controlled by a motor drive to achieve automatic storage.

[0024] When in use, the utility model provides a fire hose storage device. First, the handle 64 is rotated to control the pressure plate 5 to move to a position where it is about to contact the winding roller 3. Then, the starting end of the fire hose is clamped between the pressure rod 5 and the winding roller 3, so that the pressure plate is tightly pressed against the surface of the hose. Then, the firefighter pushes the device to move in the direction of the hose. At the same time, the hand crank handle 64 is rotated, and the main shaft 2 and the winding roller 3 are driven to rotate through the belt transmission. As the device moves forward and cooperates with the rotation of the winding roller 3, the hose is wound on the winding roller 3, and the hose is gradually wound. During the winding process, the screw 42 is driven to rotate by the meshing transmission of the main bevel gear 41 and the slave bevel gear 43, and the pressure rod 5 is synchronously controlled to move upward through the threaded cooperation of the screw 42 and the nut 44. The pressure rod 5 can make adaptive position adjustment according to the thickness of the water pipe winding, ensuring that the pressure rod 5 can always be pressed tightly against the surface of the outermost circle of the water pipe, providing a tight storage effect for the water pipe, ensuring that the water pipe is tightly stored, and before winding, the water pipe will be squeezed by the pressure rod 5 that is first contacted to discharge the residual water in the pipe, thereby realizing automatic drainage and storage of the water pipe. Example

[0025] On the basis of the first embodiment, Figure 1 As shown in Figure 2, a spray assembly 8 is provided on the front side of the storage rack 1. The spray assembly 8 includes a mounting platform 82 fixed on the upper front sides of the left and right racks, and a nozzle 81 is installed on the mounting platform 82. The nozzle 81 is located in the middle of the storage rack 1, and the nozzle corresponds to the front side of the pressure rod 5. The water inlet end of the nozzle 81 is connected to the water inlet pipe 83; during the reeling of the fire hose, the water inlet pipe 83 can be connected to the water tank of the fire truck, and the water on the fire truck enters the nozzle 81 through the water inlet pipe 83, and is sprayed on the water pipe that has not been reeled through the nozzle 81, so as to automatically wash the cigarette ash attached to the surface of the water pipe, so that the water pipe can be stored in a clean state. Example

[0026] On the basis of Example 1, the similarities between this embodiment and Example 1 are not repeated here, and the differences are as follows: In order to reduce the friction caused by the pressure plate 5 on the surface of the fire hose when the fire hose is rotated and reeled, the pressure plate can be set in the form of a roller, and the two ends of the roller are rotatably mounted on the nut 44. When the water hose is reeled, the sliding friction generated between the pressure plate and the surface of the water hose is converted into rolling friction between the roller and the surface of the water hose, thereby reducing the wear on the surface of the water hose.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
