Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a fire fighting reel with a power assist function. Background Art

[0002] The full name of the fire reel is "fire hose reel". It is a fire-fighting device composed of a valve, input pipeline, fire hose, spray gun, etc., and can spray fire extinguishing agent while quickly unfolding the hose.

[0003] For example, the public document with application number 202120452371.9 discloses an automatically reeling fire hose reel. The utility model controls the start of the rotating motor through the control switch in the reeling device, and drives the fire hose reel to rotate through the cooperation of the locking seat and the driving seat, thereby automatically reeling the fire hose. The structure is simple and reasonable, easy to use, and reduces the time spent by the user on reeling the fire hose. However, the fire hose reel has the tube body completely wrapped around the roller body, the weight of the roller body increases, and there is also a certain friction between the tube bodies, which causes firefighters to exert greater force to pull and traction in order to pull out the fire hose. The fire hose is slow to be pulled out, which seriously affects the firefighting efficiency, and is extremely manpower-consuming, affecting subsequent firefighting work.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a fire hose reel with power assist function is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a fire hose reel with power-assisting function to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire hose reel with a power-assist function, comprising a base, a support frame is fixedly installed on the upper rear end of the outer surface of the base, a horizontal plate is fixedly installed on the front side of the surface of the support frame, a fixed box is fixedly installed on the top of the support frame, the shape of the fixed box is set to be circular, and a power-assist mechanism is set on the surface of the horizontal plate.

[0007] Preferably, the power assist mechanism comprises two rotating rods rotatably arranged at the upper and lower corresponding front ends of the middle part of the opposite side of the horizontal plate, and the left ends of the rotating rods are both penetrated through the horizontal plate and fixedly provided with gears.

[0008] Preferably, the power-assisting mechanism further includes an expansion soft rubber roller fixedly arranged in the middle of the rotating rod surface, and a driving motor is arranged at the right end of the upper rotating rod penetrating through the horizontal plate, and the driving motor is fixedly arranged on the right side of the surface of the right horizontal plate.

[0009] Preferably, a winding mechanism is provided on the surface of the fixed box, and the winding mechanism comprises a through pipe rotatably provided on the inner surface of the left fixed box through a bearing.

[0010] Preferably, the winding mechanism also includes a connecting rod rotatably arranged on the inner surface of the right fixed box through a bearing, and the through tube and the connecting rod are both located on the inner surface of the fixed box and fixedly installed with a clockwork spring, the outer ring end of the clockwork spring is fixedly connected to the inner surface of the fixed box, and the through tube and the connecting rod at the opposite end both pass through the fixed box and are fixedly installed with a hollow roller.

[0011] Preferably, a water injection valve pipe is fixedly provided at the middle left portion of the outer surface of the fixed box on the left side of the upper end of the support frame, and the right end of the water injection valve pipe passes through the fixed box and is connected to the through pipe.

[0012] Preferably, a fire hose is fixedly connected to the upper right side of the surface of the hollow roller, and a spray gun is fixedly provided at the front end of the fire hose through the gap in the middle of the expansion soft rubber roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model adopts the arrangement of the power-assisting mechanism, the rotating rod, the gear, the expansion soft rubber roller and the driving motor. No manual operation is required for the firefighters to pull and extend the fire hose or to retract the fire hose, which greatly reduces the workload of the firefighters and makes the extension and recycling of the hose more time-saving and labor-saving, and more efficient. The extended fire hose will not retract due to the friction between the expansion soft rubber rollers, so that the fire hose can be extended and used more stably;

[0015] 2. The utility model is provided with a winding mechanism, a through tube, a connecting rod, a spring spring and a hollow roller. When the power-assisting mechanism pulls the fire hose to extend, the hollow roller, the through tube and the connecting rod are also driven to rotate, thereby causing the spring spring to gradually rotate and loosen. When the fire hose is recovered by the power-assisting mechanism, the hollow roller, the through tube and the connecting rod lose the pulling force of the fire hose, and then the spring spring uses its own elastic winding force to drive the hollow roller, the through tube and the connecting rod to rotate in the opposite direction, and the fire hose recovered by the power-assisting mechanism is automatically wound onto the surface of the hollow roller for bundling and storage, without the need for manual winding and collection work.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 2 As shown, a fire hose reel with power-assist function comprises a base 1, a support frame 2 is fixedly installed on the upper rear end of the outer surface of the base 1, a horizontal plate 3 is fixedly installed on the front side of the surface of the support frame 2, a fixed box 4 is fixedly installed on the top of the support frame 2, the shape of the fixed box 4 is set to be circular, and a power-assist mechanism 5 is set on the surface of the horizontal plate 3, the power-assist mechanism 5 comprises two rotating rods 501 rotatably arranged at the upper and lower corresponding front ends of the middle part of the opposite side of the horizontal plate 3, the left ends of the rotating rods 501 are all penetrated through the horizontal plate 3 and fixedly provided with gears 502, the power-assist mechanism 5 also comprises an expansion soft rubber roller 503 fixedly arranged in the middle part of the surface of the rotating rod 501, and the right end of the upper rotating rod 501 penetrates the horizontal plate 3 and is provided with a driving motor 504, and the driving motor 504 is fixedly arranged on the right side of the surface of the right horizontal plate 3.

[0023] Furthermore, the two gears 502 at the left ends of the upper and lower rotating rods 501 mesh with each other, so that the rotational force of the upper rotating rod 501 can be transmitted to the lower rotating rod 501, so that the upper and lower expansion soft rubber rollers 503 rotate in opposite directions to jointly apply a pushing force or a recovery force to extend and pull the tube body.

[0024] Furthermore, the friction between the expansion soft rubber roller 503 and the tube body makes the extended length of the tube body more stable and avoids the tube body from retracting.

[0025] Furthermore, the expansion soft rubber roller 503 is made of soft rubber material. When the fire hose 8 is filled with water, the fire hose 8 will collide and push the expansion soft rubber roller 503 to shrink, thereby avoiding the situation where the expansion soft rubber roller 503 squeezes the fire hose 8 and blocks it from discharging water.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, a winding mechanism 6 is provided on the surface of the fixed box 4, and the winding mechanism 6 includes a through pipe 601 which is rotatably provided on the inner surface of the left fixed box 4 through a bearing, and the winding mechanism 6 also includes a connecting rod 602 which is rotatably provided on the inner surface of the right fixed box 4 through a bearing, and the through pipe 601 and the connecting rod 602 are located on the inner surface of the fixed box 4 and are fixedly installed with a clockwork spring 603, and the outer ring end of the clockwork spring 603 is fixedly connected to the inner surface of the fixed box 4, and the through pipe 601 and the connecting rod 602 are both passed through the fixed box 4 and fixedly installed with a hollow roller 604 at the opposite end, and a water injection valve pipe 7 is fixedly provided on the middle left side of the outer surface of the fixed box 4 on the left side of the upper end of the support frame 2, and the right end of the water injection valve pipe 7 passes through the fixed box 4 and is connected with the through pipe 601, and a fire hose 8 is fixedly connected to the right side above the surface of the hollow roller 604, and a spray gun 9 is fixedly provided at the front end of the fire hose 8 through the middle gap of the expansion soft rubber roller 503.

[0027] Furthermore, when the assisting mechanism 5 pulls the fire hose 8 to extend, the fire hose 8 will also pull and drive the hollow roller 604, the through tube 601 and the connecting rod 602 to rotate, thereby causing the clockwork spring 603 to gradually rotate loose, so that the clockwork spring 603 itself has the potential energy to rebound and rewind, and then when the assisting mechanism 5 recovers the fire hose 8, the clockwork spring 603 uses the elastic contraction force to drive the hollow roller 604, the through tube 601 and the connecting rod 602 to rotate in the opposite direction, thereby converging and collecting the fire hose 8 recovered by the assisting mechanism 5.

[0028] Furthermore, the interior of the hollow roller 604 is connected to the fire hose 8 and also to the through pipe 601, and the through pipe 601 is connected to the water injection valve pipe 7. Therefore, after water is injected through the water injection valve pipe 7, the water flows through the through pipe 601 into the interior of the hollow roller 604 and then into the fire hose 8, thereby realizing water discharge from the spray gun 9.

[0029] Working principle: When using the fire hose reel with power-assist function, first, when using the device, the firefighter drives the upper rotating rod 501 and the expansion soft rubber roller 503 to rotate through the driving motor 504, and then uses the gear 502 to mesh to make the lower rotating rod 501 and the expansion soft rubber roller 503 rotate synchronously in opposite directions, so that the upper and lower expansion soft rubber rollers 503 can fit the surface of the fire hose 8 and rotate to push the fire hose 8 to automatically extend, driving the hollow roller 604, the through pipe 601 and the connecting rod 602 to rotate, and then the clockwork spring 603 gradually rotates and loosens, and the firefighter holds the spray gun 9 to pull the extended fire hose 8 to move. After extending to the required length, the driving motor 504 stops, and the extended fire hose 8 is subjected to the friction of the expansion soft rubber rollers 503. The fire hose 8 is automatically retracted and stored on the surface of the hollow roller 604 by driving the rotating rod 501 in the reverse direction.
