Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of fire-fighting equipment, and particularly relates to a foldable portable fire hose reel. BACKGROUND

[0002] A fire hose is a flexible hose used to transport high-pressure water or foam fire-retarding material. Both ends of the fire hose have metal fittings that can be connected to another fire hose to extend the delivery distance or to a water cannon head to increase the jet pressure. When not in use, the fire hose is coiled into a disc shape for easy opening at the time of use to connect the water cannon head and fire hydrant or fire truck. After use, the fire hose needs to be coiled up for storage for next use.

[0003] Currently, fire personnel mainly use a fire hose reel to coil up the fire hose. The existing fire hose reel generally comprises a base and a coiling mechanism arranged on the base. The coiling mechanism comprises a squeezing drainage assembly and a hose coiling assembly, and the hose coiling assembly can be driven manually or electrically to realize coiling of the fire hose. For example, the Chinese utility model patent with the authorization announcement number CN213555076U discloses a fire hose rapid coiling device, which comprises a base and a coiling assembly arranged on the base. The coiling assembly comprises a pair of squeezing rollers arranged at intervals and capable of relative movement, and an extrusion channel is formed between the two squeezing rollers for the fire hose to pass through. The coiling assembly further comprises a coiling shaft located on one side of the extrusion channel. A coiling disc capable of rotating with the coiling shaft and being detachable is arranged on the coiling shaft. A ratchet mechanism for controlling one-way rotation of the coiling shaft is fixed to one end of the coiling shaft.

[0004] Although the above-mentioned fire hose rapid coiling device can rapidly coil the used fire hose, the used fire hose can pass through the extrusion channel before coiling to avoid residual liquid in the fire hose after extrusion, but it is relatively bulky and does not have a folding function, so it is not convenient to carry and store, and the weight and working intensity of the fire personnel are increased in the actual use process.

[0005] Therefore, there is an urgent need in the field for a foldable portable fire hose reel to solve the above technical problems. UTILITY MODEL CONTENTS

[0049] in combination with Figure 1 、 Figure 2 and Figure 3 , the foldable portable fire hose reel comprises a base 100 and a winding mechanism;

[0050] The base 100 is the basic part of the fire hose reel, mainly used for mounting and supporting other components; the base 100 comprises a base frame 110, a positioning plate 120 and a folding frame 130;

[0051] The base frame 110 is in the shape of an arch as a whole, which comprises a first arc segment 111 and a first straight segment 112 connected to both ends of the first arc segment 111 respectively; the arch-shaped base frame 110 is simple and light in structure and good in stability, which can fully utilize the mechanical properties of the material to ensure that the base frame 110 has a large proportion of hollow parts while also having high strength, so as to provide stable support for the fire hose reel and disperse the acting force to the ground;

[0052] At least one end of the first straight segment 112 is provided with the positioning plate 120, and the positioning plate 120 is provided with a locking mechanism 140; the positioning plate 120 is an important component of the base 100, mainly used to position and fix the folding frame 130 together with the locking mechanism 140, so that the folding frame 130 remains in the folded state or the use state; the structure of the positioning plate 120 can be various, such as: quarter fan, semicircle, rectangle, trapezoid and the like; the locking mechanism 140 is mainly used to lock and fix the folding frame 130, which can be a buckle locking mechanism, a bolt locking mechanism, a clamp locking mechanism and the like;

[0053] The folding frame 130 is in the shape of an arch as a whole, which comprises a second arc segment 131 and a second straight segment 132 connected to both ends of the second arc segment 131 respectively; the arch-shaped folding frame 130 is simple and light in structure and good in stability, which can fully utilize the mechanical properties of the material to ensure that the folding frame 130 has a large proportion of hollow parts while also having high strength, so as to mount and support other components of the fire hose reel and facilitate switching between the folded state and the use state; the structure of the folding frame 130 can be exactly the same as that of the base frame 110, or can be different, but usually the length of the second straight segment 132 differs from the length of the first straight segment 112 by less than or equal to twice the thickness of the positioning plate 120;

[0054] The folding frame 130 is rotatably connected with the positioning plate 120 through the end of the second straight segment 132, and can be rotated to a folding state of being attached to the base frame 110, and a use state of being locked and fixed by the locking mechanism 140 with an included angle θ between the base frame 110, wherein 45°≤θ≤90°; the included angle between the base 100 and the folding frame 130 generally refers to the included angle between the plane where the base 100 is located and the plane where the folding frame 130 is located, and limiting the included angle θ to be not less than 45° and not more than 90° can ensure that the firefighter can more conveniently operate the winding mechanism to wind the fire hose when in the use state;

[0055] The winding mechanism is arranged on the folding frame 130 through the mounting rack 200; the winding mechanism is the main part of the fire hose winder, and is used to wind the scattered fire hose into a disc shape; the winding mechanism generally comprises an extrusion and drainage assembly for extruding and discharging the fire-retardant substances in the fire hose, and a hose winding assembly for winding the fire hose; the mounting rack 200 is a component for mounting and fixing the winding mechanism on the folding frame 130, and is generally arranged in the area surrounded by the folding frame 130; the mounting rack 200 can have various structures, such as an “X” shaped structure, a “Y” shaped structure, a “Z” shaped structure, an “A” shaped structure, and the like.

[0056] The base of the fire hose winder mainly comprises the base frame 110, the positioning plate 120 and the folding frame 130, and the base frame 110 and the folding frame 130 are both frame structures with an overall arc shape, and have a large proportion of hollow parts, i.e. the volume proportion of the hollow parts in the overall structure is greater than that of the solid parts, so that the fire hose winder is more lightweight, and thus it is convenient for the firefighter to carry and transfer it; moreover, the folding frame 130 is rotatably connected with the positioning plate 120 through the end of the second straight segment 132, and can be rotated to the use state of being locked and fixed by the locking mechanism 140 with an included angle θ between the base frame 110, and can be rotated to the folding state of being attached to the base frame 110 after use, which further facilitates carrying, and at the same time, the size of the fire hose winder can be changed after folding, so that the space required by the fire hose winder is reduced, and thus the fire hose winder is also convenient to store and store. Since the included angle between the folding frame 130 and the base frame 110 is not less than 45° and not more than 90° when in the use state, the center of gravity of the fire hose winder can be ensured to be inside the whole body, and thus the gravity of the folding frame 130 and the parts thereon and the force applied by the firefighter when winding the fire hose can be mostly concentrated on the base frame 110, so that the fire hose winder has good stability during use; if the fire hose to be wound is very heavy, and the fire hose winder is unstable, roadside stones can be used to press on the base frame 110 or the firefighter can step on the base frame 110 to increase the weight of the base frame 110, so that the base frame 110 can be kept stable.

[0057] In combination Figures 1 to 5 As shown in some embodiments, the locking mechanism 140 includes a first positioning hole 141, a locking hole and a locking pin 142; the first positioning hole 141 is opened on the positioning plate 120, and there are at least two first positioning holes 141 which are distributed along a circular arc path 144 with the center of the circular arc path 144 on the axis of the second straight section 132; the first connecting line between the center of the first positioning hole 141 and the center of the circular arc path 144 is the first connecting line, and the included angle between the first connecting line and the base frame 110 is not less than 45° and not greater than 90°; the locking hole is opened on the second arc section 131 and can rotate to a position coaxial and communicated with any one of the first positioning holes 141; the locking pin 142 is used for inserting into the coaxial and communicated locking hole and the first positioning hole 141 to lock and fix the folding frame 130, so that the folding frame 130 remains in the use state. The circular arc path 144 is a virtual line for guiding the opening of the hole on the positioning plate 120, which actually does not exist and can be drawn on the positioning plate 120 before the first positioning hole 141 is opened. The locking hole is blocked by the positioning plate 120 and is not shown in the figure. The locking mechanism 140 not only has a simple structure, but also has a good locking and fixing effect on the folding frame 130, and by opening two or more first positioning holes 141 on the positioning plate 120, the folding frame 130 can be locked and fixed at different angle positions by the locking pin 142, so as to facilitate the use of firefighters of different heights, body shapes or different operation habits. The locking pin 142 can be various, and is preferably a spring bolt.

[0058] In combination Figures 1 to 5 As shown in some embodiments, the locking mechanism 140 further includes a second positioning hole 143 opened on the positioning plate 120, the center of the second positioning hole 143 is on the circular arc path 144, the second connecting line between the center of the second positioning hole 143 and the center of the circular arc path 144 is the second connecting line, and the included angle between the second connecting line and the base frame 110 is less than 1°; the locking hole can also rotate to a position coaxial and communicated with the second positioning hole 143; the locking pin 142 is also used for inserting into the coaxial and communicated locking hole and the second positioning hole 143 to lock and fix the folding frame 130, so that the folding frame 130 remains in the folded state. Through the second positioning hole 143, the firefighter can fix the folding frame 130 in the folded state, and then grab the base frame 110 or the folding frame 130 to lift the entire fire hose reel collector, further facilitating the carrying and transfer of the fire hose reel collector.

[0059] In combination Figure 1As shown, in some embodiments, the second straight segment 132 is parallel to the first straight segment 112, and the lower edge of the second straight segment 132 is higher than the upper edge of the first straight segment 112. In this way, the base frame 110 and the folding frame 130 can be effectively attached in the folded state, further reducing the space occupied by the fire hose reel, and at the same time, the base frame 110 can form a more stable support for the folding frame 130 and the components thereon when in use, further improving the stability of the fire hose reel during use.

[0060] In some embodiments, a handle structure 150 is provided on the base frame 110 and / or the folding frame 130 to further facilitate the carrying of the fire hose reel by firefighters. The handle structure 150 can be of various types, such as a flexible or elastic grip, a wavy grip that facilitates cooperation with curved fingers, or a long circular hole-shaped grip that facilitates the passage of a palm. Figure 5 As shown, the handle structure 150 is preferably a wavy grip provided on the inner side of the vault of the second arc segment 131.

[0061] For example, the handle structure 150 can be a long circular hole-shaped grip provided on the inner side of the vault of the second arc segment 131. Figure 1 Or Figure 5 As shown, in some embodiments, the mounting frame 200 includes a cross- frame rod 210, a first support rod 220, and a second support rod 230; the cross-frame rod 210 is provided in the area enclosed by the folding frame 130 and is parallel to the second straight segment 132; both ends of the cross-frame rod 210 are connected to the second arc segment 131; the middle part of the cross-frame rod 210 is provided with a mounting table 211; one end of the first support rod 220 is connected to the mounting table 211, and the other end is connected to one end of the second arc segment 131; one end of the second support rod 230 is connected to the mounting table 211, and the other end is connected to the other end of the second arc segment 131. The mounting frame 200 not only has a simple structure, but also does not increase the weight of the base 100 too much, and the triangular structure formed by the first support rod 220, the second support rod 230, and the second straight segment 132 can provide stable support for the cross-frame rod 210 and the mounting table 211, facilitating the installation of the winding mechanism.

[0062] Further in combination Figures 1 to 5As shown, in some embodiments, the winding mechanism comprises a squeezing drainage assembly 300, the squeezing drainage assembly 300 comprises a first squeezing roller 310 and a second squeezing roller 320 which are arranged at intervals on the first supporting rod 220 and can be relatively close and far away, and an elastic member which can drive the first squeezing roller 310 and the second squeezing roller 320 to be relatively close; a water hose passing through the squeezing part is formed between the first squeezing roller 310 and the second squeezing roller 320. The squeezing drainage assembly 300 can effectively squeeze the water hose by driving the first squeezing roller 310 and the second squeezing roller 320 to be relatively close through the elastic member during the process that the fire hose passes through the squeezing part, so as to squeeze out the fire-retardant substances in the water hose. Not only the fire-retardant substances can be avoided to remain in the fire hose, but also the volume and weight of the wound fire hose can be smaller and lighter. The structure of the first squeezing roller 310 and the second squeezing roller 320 is basically the same, and each generally comprises a roller shaft and a roller cylinder which is sleeved on the roller shaft. The elastic member can be various, for example, rubber band, gas rod, spring 330, etc.

[0063] For example Figure 1 Or Figure 5 As shown, in some embodiments, at least two roller mounting holes 221 which are arranged at intervals are formed on the first supporting rod 220, and the connecting end of the first squeezing roller 310 is connected with one of the roller mounting holes 221; the second squeezing roller 320 is slidably arranged on the first supporting rod 220 and is closer to the mounting table 211 than the first squeezing roller 310; the first supporting rod 220 is provided with a stop piece 222 which is closer to the mounting table 211 than the second squeezing roller 320; the elastic member is a spring 330, the spring 330 is sleeved on the first supporting rod 220, one end of the spring 330 is connected with or abuts against the stop piece 222, and the other end of the spring 330 is connected with or abuts against the second squeezing roller 320. By forming at least two roller mounting holes 221 which are arranged at intervals on the first supporting rod 220, the first squeezing roller 310 can be installed at different positions to adjust the initial width of the water hose passing through the squeezing part, so as to facilitate winding the fire hose with different sizes or different squeezing force requirements, and improve the practicability of the fire hose winder.

[0064] For example Figures 1 to 5 As shown, in some embodiments, the winding mechanism further comprises a water hose winding assembly 400, the water hose winding assembly 400 comprises a winding rod 410 and a handle 420; the winding rod 410 is rotatably arranged on the mounting table 211, and the water hose winding part of the winding rod 410 is on the same side of the folding frame 130 as the water hose passing through the squeezing part; the power output end of the handle 420 is in transmission connection with the power input end of the winding rod 410, and the transmission connection can be generally achieved by a shaft coupling, a threaded coaxial connection, a connecting piece coaxial connection, etc. The water hose winding assembly 400 has a simple structure, and the fire fighters can wind up the fire hose which is partially sleeved on the winding rod 410 by hand shaking the handle 420.

[0065] In some embodiments, in order to avoid the skidding of the fire hose, an anti-skid layer is usually arranged on the winding rod 410.

[0066] In some embodiments, in order to facilitate the firemen to drive the winding rod 410 to rotate, so as to reduce the labor intensity, the winding rod 410 is usually rotatably arranged through a bearing.

[0067] In combination Figures 1 to 4 As shown in some embodiments, the winding rod 410 is in the shape of "mu" and includes two straight rods with different lengths, wherein the rear end of the shorter straight rod is connected with the longer straight rod, the rear end of the longer straight rod serves as the power input end of the winding rod 410, and the front ends of the two straight rods are not connected, forming the hose winding part of the winding rod 410. The winding rod 410 has simple structure, is convenient for sleeving the fire hose, and can utilize the rotation difference between the two straight rods to quickly wind the fire hose partially sleeved on the winding rod 410.

[0068] In combination Figures 1 to 5 As shown in some embodiments, in order to improve the smoothness and efficiency of winding the fire hose and prevent the hose from being skewed during the winding process, the rotational center line of the winding rod 410 is usually perpendicular to the plane where the folding frame 130 is located.

[0069] In combination Figures 1 to 4 As shown in some embodiments, the handle 420 includes a transmission rod 421 and a crank 422; the front end of the transmission rod 421 serves as the power output end of the handle 420; the crank 422 is in the shape of "Z" and has one end movably connected with the rear end of the transmission rod 421; so as to fold up the handle 420 when it is needed to be carried and stored, further improving the portability. The one end of the crank 422 and the rear end of the transmission rod 421 can be movably connected through a hinge, a universal joint or the like, and when in use, the one end of the crank 422 and the rear end of the transmission rod 421 are coaxially fixedly connected together through a connecting piece or a pin.

[0070] In combination Figures 1 to 5 As shown in some embodiments, the hose winding assembly 400 further includes a tensioning roller 430 arranged on the second supporting rod 230, and the tensioning roller 430 is closer to the second straight line segment 132 than the first extruding roller 310. In this way, the tensioning roller 430 can be used as a winding point of the fire hose, so as to adjust the fire hose to be wound into a "Z" shape, so as to increase the winding resistance and improve the winding tightness.

[0071] As shown in some embodiments, or Figure 1 As shown in some embodiments, or Figure 5As shown, in some embodiments, to add support to the fire hose during the process of winding up the fire hose, the fire hose winding assembly 400 further comprises a fire hose retaining ring 440 arranged on the mounting table 211, and the plane where the fire hose retaining ring 440 is arranged is coplanar with the plane where the folding frame 130 is arranged.

[0072] In combination Figure 1 As shown, the method of winding up the fire hose by using the fire hose winder is as follows: the fire hose is folded in half at the middle part, and the folded part of the fire hose is taken as the head part to pass through the pressing part first, and then the fire hose is sleeved on the winding rod 410 after passing through the lower edge of the tensioning roller 430; then, the firefighter rotates the handle 420 to drive the winding rod 410 to rotate to wind up the fire hose; the fire hose discharges the fire-retardant substance from the metal joint under the pressing action of the first pressing roller 310 and the second pressing roller 320, and improves the tightness of the winding of the fire hose under the tensioning action of the tensioning roller 430; finally, when the metal joint of the fire hose reaches the position where the fire hose passes through the pressing part, the rotation of the handle 420 is stopped, and the firefighter takes down the wound fire hose in a disc shape, and folds up the metal joint.
