Description

Technical Field

[0001] The present invention relates to the technical field of fire hose retraction, and particularly to a foldable remote-controlled electric fire hose retraction device. Background Art

[0002] A fire hose is a flexible hose used to transport high-pressure water or flame-retardant liquids such as foam. A fire hose is an important fire-fighting equipment in fire extinguishing. After each fire fighting and rescue operation, it needs to be retracted. Since the fire hose is relatively long, a retraction device is required for retraction and storage.

[0003] Traditional fire hoses have a rubber inner lining and are wrapped with linen fabric on the outer surface; advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose are equipped with metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spraying pressure.

[0004] In the prior art, when the fire hose is retracted again after use at the construction site, it is usually manually retracted. The retraction is not tight, the coil is not round, and the hose layers are uneven, making it difficult to ensure that the retraction effect after retraction is the same as before use. Moreover, after the fire hose is used, due to the large amount of impurities in the fire field environment, the surface of the fire hose will adhere to impurities such as sand after being dragged on the ground. If it is not cleaned, after direct retraction, the sharp sand grains will cause scratches and wear on the surface layer (rubber or composite material) of the hose during retraction. Long-term accumulation may cause cracks or perforations, affecting the service life of the fire hose.

[0005] Based on this, a foldable remote-controlled electric fire hose retraction device is proposed. Summary of the Invention

[0033] The present invention provides a foldable remotely controlled electric retractable fire hose device through improvement. The technical solution of the present invention is as follows:

A plurality of bristles 21 are fixedly installed on the surfaces of the rotating pipe 7 and the rotating pipe 9. Driving gears 23 are fixedly installed on the surfaces of the rotating pipe 7 and the rotating pipe 9. By means of the two driving gears 23, the rotating directions of the rotating pipe 7 and the rotating pipe 9 can be made opposite, thereby improving the cleaning effect. The bristles 21 are made of hard bristles 21, which can reduce wear and increase the service life.

[0037] Auxiliary air-blowing cleaning unit. The auxiliary air-blowing unit includes a sealing cylinder 26 fixedly connected to the base 1. A piston plate 27 is slidably connected to the inner wall of the sealing cylinder 26. The surface of the piston plate 27 is made of rubber material, a flexible material, which can improve the fit with the inner wall of the sealing cylinder 26, thereby improving airtightness. One side of the piston plate 27 is fixedly connected to a connecting rod 20. One end of the sealing cylinder 26 is fixedly communicated with an air inlet pipe 28 and a blowing pipe 29 respectively. One end of the blowing pipe 29 is fixedly communicated with the inner wall of the base 1. The blowing pipe 29 is communicated with the base 1, which can realize synchronously blowing air to the rotating pipe 7 and the rotating pipe 9. A filter screen can be arranged inside the air inlet pipe 28 to prevent large impurities in the air from being inhaled and causing secondary pollution to the fire hose.

[0038] As Figure 2 and Figure 4 shown, a follower rod 24 is fixedly connected to the surface of the connecting rod 20. One end of the follower rod 24 is fixedly connected to a double-sided rack 25. The double-sided rack 25 meshes with the two driving gears 23 respectively.

[0039] As Figure 5 shown, check valves 30 are fixedly installed on the surfaces of the air inlet pipe 28 and the blowing pipe 29. A plurality of air blowing holes 22 are formed on the surfaces of the rotating pipe 7 and the rotating pipe 9. The check valve 30 is a prior art and will not be described in detail here. The setting of the air blowing holes 22 can clean the bristles 21 and at the same time clean the surface of the fire hose. A number of air blowing holes 22 are provided and are annularly arrayed on the surfaces of the rotating pipe 7 and the rotating pipe 9.

[0040] As Figure 4 and Figure 6 shown, a winding and hanging device 5 is rotatably connected to one side of the fixed seat 4. A motor 31 is fixedly installed on the inner wall of the fixed seat 4. The output end of the motor 31 is fixedly connected to one side of the winding and hanging device 5.

Through the limitation of the fixed bracket 13 and the limiting plate 14, the reciprocating movement of the second rotating plate 17 can be realized. During the reciprocating movement of the second rotating plate 17, the two pull rods 18 can be reciprocally pulled to rotate, so as to drive the horizontal movement of the two connecting rods 20. Through the horizontal movement of the two connecting rods 20, the horizontal movement of the two follower rods 24 and the reciprocating sliding of the two piston plates 27 inside the two sealing cylinders 26 can be synchronously driven;

[0046] Through the movement of the two follower rods 24, the reciprocating movement of the two double-sided racks 25 can be driven, so as to drive the driving gears 23 on the surfaces of the first rotating pipe 7 and the second rotating pipe 9 to rotate, so as to realize the rotation of the first rotating pipe 7 and the second rotating pipe 9. The bristles 21 arranged on the cooperation surface can sweep the surface impurities of the fire hose during the winding process;

[0047] Through the reciprocating sliding of two piston plates 27, in cooperation with the air inlet pipe 28 and the air blowing pipe 29, external air can be inhaled into the interior of the sealed cylinder 26 and then blown through the air blowing pipe 29 into the interiors of the first rotating pipe 7 and the second rotating pipe 9, and then blown out from the opened air blowing holes 22, which can clean the bristles 21 provided on the surfaces of the first rotating pipe 7 and the second rotating pipe 9. At the same time, it can further clean the impurities on the surface of the fire hose, thereby improving the cleaning effect of the fire hose.
