Description

Technical Field

[0001] This invention belongs to the technical field of fire-fighting equipment auxiliary equipment, specifically providing a fire hose washing device. Background Technology

[0002] Fire hoses are flexible tubes used to deliver high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Newer fire hoses are made from new polymer materials such as polyurethane. Both ends of the fire hose are fitted with metal connectors, which can be connected to water pipes to supply flame-retardant liquids, to other fire hoses to extend the delivery distance, or to nozzles to increase the pressure of the flame-retardant liquid spray.

[0003] Fire hoses commonly used by fire departments accumulate a large amount of mud and dirt after each mission. To extend their lifespan and facilitate storage, it's essential to thoroughly clean them after each use. Inadequate cleaning can lead to damage and contamination, affecting their proper function. The quality of the fire hoses directly impacts the entire firefighting process; therefore, proper maintenance and care are crucial. During washing, the hoses should be thoroughly cleaned and allowed to dry completely before storage.

[0004] However, the traditional cleaning process for fire hoses mainly involves manual brushing or machine washing. After use, the fire hoses are first rolled up into coils on-site for easy transport, and then laid out in a designated cleaning area for manual or machine washing. After washing, the hoses are dried and then rolled up again for storage. This entire manual cleaning process is not only time-consuming but also requires multiple unrolling and rolling of the hoses, consuming a great deal of physical strength. Current machine washing of fire hoses also requires repeated unrolling and rolling, consuming considerable physical strength and time. Furthermore, regardless of whether manual or machine washing is used, the cleaning process involves extensive rinsing, resulting in significant water waste. Moreover, the subsequent drying process requires further unrolling and rolling, making the overall efficiency extremely low.

[0005] Accordingly, there is a need in the field for a new fire hose washing device to solve the problem of low efficiency in existing fire hose washing processes. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, namely the low efficiency of the fire hose washing process, this invention provides a fire hose washing device, including a drive unit and a washing tub. A pulsator is provided at the bottom of the washing tub, and the drive unit is connected to the pulsator. A tray is also provided inside the washing tub, located above the pulsator, and the tray protrudes towards the top of the washing tub.

[0007] In the preferred technical solution of the above-mentioned fire hose washing equipment, an annular support rib is provided on the inner side of the washing tub, and the tray is mounted on the annular support rib.

[0008] In the preferred embodiment of the above-mentioned fire hose washing equipment, a support is provided at the bottom of the tray, and the tray is supported at the bottom of the washing tub by the support.

[0009] In the preferred technical solution of the above-mentioned fire hose washing equipment, a pipe head storage structure is provided inside the washing tub. The pipe head storage structures are symmetrically arranged and at the same height.

[0010] In the preferred technical solution of the above-mentioned fire hose washing equipment, the pipe head storage structure is a boss, and the boss is provided with a groove-shaped structure that runs vertically through it. The diameter of the groove-shaped structure is smaller than the diameter of the fire hose head.

[0011] In the preferred embodiment of the fire hose washing equipment described above, the fire hose washing equipment further includes an outer tub, and the washing tub is disposed inside the outer tub.

[0012] In the preferred technical solution of the above-mentioned fire hose washing equipment, a spiral channel is provided on the tray.

[0013] In the preferred technical solution of the above-mentioned fire hose washing equipment, the tray has a mesh structure.

[0014] In the preferred technical solution of the above-mentioned fire hose washing equipment, the surface of the tray is provided with segmented steps.

[0015] In the preferred technical solution of the above-mentioned fire hose washing equipment, the surface of the tray is a wavy surface.

[0016] Those skilled in the art will understand that the present invention provides a fire hose washing device, including a drive unit and a washing tub. A pulsator is provided at the bottom of the washing tub, the drive unit is connected to the pulsator, and a tray is also provided inside the washing tub. The tray is located above the pulsator and protrudes towards the top of the washing tub.

[0017] With the above-described configuration, the fire hose washing device of the present invention allows the fire hoses to be placed in a coiled state without needing to be unrolled during the washing process. The tray protruding from the top of the washing tub allows the coiled fire hoses to naturally unwind and unroll, increasing the gaps between the hoses. The water flow, driven by the impeller, can enter the gaps between the hoses, effectively washing away mud and dirt. After washing, the fire hoses can be removed in their coiled state without needing to be reassembled. The entire washing process is more convenient, water-saving, and efficient.

[0018] Those skilled in the art will understand that traditional fire hose washing processes require unrolling the fire hoses for manual rinsing, followed by drying, and then rerolling and storing them. This process involves multiple unrolling and rerolling steps, consuming significant physical labor and time, and also resulting in substantial water waste. In the preferred embodiment of this invention, a pulsator is installed inside the washing tub, with a tray above it. The tray has a raised structure towards the top of the tub. When washing fire hoses, they can be placed on the tray in their coiled state. Because the tray is raised, the coiled hoses naturally loosen and unfurl, increasing the gaps between them. During washing, the rotation of the pulsator drives the water flow, allowing the water to enter the gaps between the fire hoses and effectively wash away mud, sand, and dirt. The tray has a mesh structure, allowing washed-off mud and dirt to pass through and reach the bottom of the washing tub, where it is then drained with the water flow through the drain valve, achieving effective washing. After washing, fire hoses can also be rinsed and dehydrated. After dehydration, the fire hoses can be removed in their coiled state, eliminating the need for secondary storage. The entire washing process is more convenient, efficient, and water-saving. Attached Figure Description

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the specification describes it as a fire hose washing device, the present invention can obviously be applied to the washing of various other similar items, as long as the items to be washed have characteristics similar to fire hoses.

[0029] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] First refer to Figure 1The fire hose washing device of the present invention will be described. Figure 1 This is a schematic diagram of a fire hose washing device provided in an embodiment of the present invention.

[0032] like Figure 1 As shown, in order to solve the problem of low efficiency in the existing fire hose washing process, the fire hose washing equipment of the present invention includes a drive device 2 and a washing tub 1. A pulsator 11 is provided at the bottom of the washing tub 1. The drive device 2 is connected to the pulsator 11. A tray 12 is also provided inside the washing tub 1. The tray 12 is located above the pulsator 11 and the tray 12 protrudes towards the top of the washing tub 1.

[0033] The advantages of the above-described setup are as follows: The fire hose washing equipment includes a tray 12 with an upward-convex structure. After the fire hose is placed into the washing tub 1 in a coiled state, the upward-convex structure of the tray 12 allows the coiled fire hose to naturally loosen and unfurl, increasing the gaps between the fire hoses. The drive device 2 drives the impeller 11 to move. After water is injected into the washing tub 1, the impeller 11 drives the water flow, allowing the water to enter the gaps between the fire hoses and achieve the washing process. Because the coiled fire hose is naturally unfurled, the increased gaps between the fire hoses allow water to enter the gaps, effectively washing the fire hoses and removing dirt and silt. The dirt and silt can then be effectively discharged through the drain valve 4 with the water flow.

[0034] The following is further reference Figures 1-6 The fire hose washing device of the present invention will be described in detail.

[0035] like Figure 1 As shown, in one possible implementation, an annular support rib 13 is provided on the inner side of the washing tub 1, and the tray 12 is mounted on the annular support rib 13.

[0036] The advantages of the above arrangement are as follows: An annular support rib 13 is provided inside the washing tub 1, and the tray 12 is mounted on the annular support rib, ensuring effective isolation between the tray 12 and the impeller 11, and guaranteeing the stability of the tray 12 structure. Simultaneously, during the washing process, the impeller 11 rotates, driving water flow to clean and wash the fire hose, while the tray remains fixed and does not shift with the rotation of the impeller.

[0037] In one possible implementation, a support is provided at the bottom of the tray 12, and the tray 12 is supported at the bottom of the washing tub 1 by the support.

[0038] The advantages of the above arrangement are as follows: the tray 12 is mounted on the bottom of the washing tub 1 via a bracket, resulting in a simpler structure. This also ensures effective isolation between the impeller 11 and the tray 12. Furthermore, during the washing process, the impeller 11 rotates, driving water flow to effectively rinse and wash the fire hose, ensuring a good washing effect. The tray, however, remains fixed and does not shift with the rotation of the impeller.

[0039] like Figure 1 As shown, in one possible implementation, a pipe head storage structure 14 is provided inside the washing tub 1. The pipe head storage structures 14 are symmetrically arranged and at the same height.

[0040] The advantages of the above-mentioned setup are as follows: Since fire hose ends are generally made of metal and are quite heavy, if the ends are not secured during the fire hose washing process, they will move with the water flow as the impeller rotates, potentially causing collisions. This not only affects the washing process but can also damage the washing equipment. The washing tub 1 has a hose end storage structure 14 inside, which secures the fire hose ends during washing, ensuring that they do not move or collide with the impeller 11 during rotation, thus preventing damage to the washing tub 1 and further affecting the washing effect. The hose end storage structures 14 are symmetrically arranged and at the same height. This design ensures balanced weight distribution within the washing tub 1, preventing eccentricity caused by weight imbalance during washing and spin-drying, which could lead to machine displacement and damage to the washing equipment.

[0041] like Figure 1 and Figure 2 As shown, in one possible implementation, the pipe head receiving structure 14 is a boss, and a groove-shaped structure that runs vertically through the boss is provided on the boss. The diameter of the groove-shaped structure is smaller than the diameter of the fire hose head.

[0042] The advantages of the above-described configuration are as follows: a boss is provided on the inner side of the washing tub 1, and this boss structure can be integrally formed with the washing tub. In a preferred embodiment, the boss is an L-shaped structure, and correspondingly, a slot structure is also provided on the inner side of the washing tub 1. The L-shaped structure engages with the slot structure on the washing tub 1 and is fixed to the inner side of the washing tub 1. The boss is a detachable structure. A vertically penetrating groove structure is provided on the boss, with the groove width being smaller at the edges and larger at the center. Due to the special structure of the fire hose head, the end of the fire hose with the head can be inserted into the groove from the narrower edge and placed in the wider groove structure. The diameter of the wider groove structure is smaller than the diameter of the head. During the washing process of the fire hose, the hose partially sinks, and the head is effectively fixed by the boss, preventing the head from falling off during the washing process and causing impact or damage to the washing equipment.

[0043] In one possible implementation, the fire hose washing equipment also includes an outer tub 5, with the washing tub 1 disposed inside the outer tub 5.

[0044] The advantages of the above-mentioned setup are as follows: the fire hose is mounted on an outer tub 5, which effectively protects the washing tub 1 and its internal structure. A housing is also installed outside the outer tub, serving as the overall support for the entire washing equipment and enclosing all electrical components, the outer tub, and the washing tub.

[0045] like Figure 4 As shown, in one possible implementation, a spiral channel 121 is provided on the tray 12.

[0046] The advantages of the above arrangement are as follows: the tray 12 is provided with multiple spiral channels 121 facing two different directions. During the washing process, the impeller 11 first rotates in one direction, driving the water flow in the same direction. The water flow changes its speed and direction by passing through the spiral channels 121 in the same direction. The water flow coming out of the spiral channels can reach the fire hose, which can further achieve effective flushing of the fire hose. Correspondingly, when the impeller 11 rotates in the other direction, the water flow passes through the spiral channels 121 in the corresponding direction. After the water flow changes its speed and direction, it further effectively flushes the fire hose.

[0047] like Figure 2 and Figure 3 As shown, in one possible implementation, the tray 12 has a mesh structure.

[0048] The advantages of the above-described configuration are as follows: The tray 12 has a mesh structure, which allows for the removal of a significant amount of mud and dirt during the fire hose washing process. This removed mud and dirt can reach the bottom of the washing tub 1 through the mesh structure. After washing, the removed mud and dirt can be effectively discharged from the washing tub 1 through the drain valve 4. Preferably, the tray 12 is made of rigid plastic or a metal woven structure, capable of bearing the weight of the fire hose. When the tray 12 is made of rigid plastic, it has multiple small holes to facilitate the discharge of mud and dirt. When the tray 12 is made of metal woven mesh, it is a metal woven mesh structure capable of bearing the weight of the fire hose.

[0049] like Figure 5 As shown, in one possible implementation, the surface of the tray 12 is provided with segmented steps.

[0050] The advantages of the above-described arrangement are as follows: The surface of the tray 12 is provided with segmented steps. When the fire hose is placed in the washing tub 1 in a coiled state, the lower part of the fire hose contacts the steps of different heights. Based on the fire hose naturally unwinding and spreading out, this allows for more stable dragging. The range of motion of the hose itself is reduced, and the gaps between the hose sections are further increased, which is more conducive to the water flow washing the hose and cleaning away mud, sand, and stains. Preferably, the segmented steps are a one-piece molded structure.

[0051] like Figure 6 As shown, in one possible implementation, the surface of the tray 12 is a wavy surface.

[0052] The advantages of the above-described arrangement are as follows: the surface of the tray 12 is wavy. When the fire hose is placed in the washing tub 1 in a coiled state, the height difference between the fire hose and the structure of the tray 12 increases. Based on the fire hose naturally unwinding and spreading out, the gap between the fire hoses can be further increased. Under the action of water flow, mud, sand, stains, etc., can be effectively washed away through the troughs of the wavy surface. Preferably, the tray 12 with the wavy surface is a one-piece molded structure.

[0053] Specifically, the washing tub 1 of the fire hose washing equipment is equipped with a reducer 3 at the bottom. The reducer 3 has a dewatering shaft 32 and a washing shaft 31. The washing shaft 31 is connected to a pulsator 11, which is fastened to the washing shaft 31 by pulsator screws 111. The dewatering shaft 32 is connected to the washing tub 1. The reducer 3 can drive the washing shaft 31 and the dewatering shaft 32 to rotate separately according to washing needs. When washing is required, the reducer 3 drives the washing shaft 31 to rotate, which in turn drives the pulsator 11 to rotate. During the rotation of the pulsator 11, water flows with it, achieving the washing process of the fire hose. When dewatering is required, the reducer 3 drives the dewatering shaft 32 to rotate, which in turn drives the washing tub 1 to rotate, achieving the dewatering purpose. The reducer 3 is connected to the drive unit 2 via a belt, and the drive unit 2 provides power to the reducer 3 during rotation. After washing, fire hoses can undergo further rinsing and dehydration. Once dehydrated, the fire hoses can be taken out directly in a coiled state without needing a secondary storage process.

[0054] In summary, the fire hose washing device of the present invention solves the problem of low efficiency in the fire hose washing process by setting an upwardly raised tray 12 above the impeller 11. Specifically, the fire hose washing device of the present invention includes a drive device 2 and a washing tub 1. The impeller 11 is set at the bottom of the washing tub 1, and the drive device 2 is connected to the impeller 11. The tray 12 is also set inside the washing tub 1, and the tray 12 is located above the impeller 11, with the tray 12 raised towards the top of the washing tub 1. The fire hose can be placed flat on the tray 12 in a coiled state. Since the tray 12 has a structure that is raised in the middle and lower around the edges, after the fire hose is placed in the washing tub in a coiled state, it can naturally loosen and spread out, increasing the gap between the fire hoses. During the washing process driven by the impeller 11, the mud, sand, and stains on the fire hose can be effectively removed, thereby achieving the purpose of effective washing. The tray 12 has a mesh structure, allowing mud, sand, and stains washed away during the fire hose washing process to reach the bottom of the washing tub 1 through the mesh structure. After washing, these mud, sand, and stains can be discharged with the water flow through the drain valve 4. The fire hose washing equipment of this invention also has a dehydration function. After washing, the reducer 3 drives the washing tub 1 to rotate via the dehydration shaft 32 to achieve the purpose of dehydrating the fire hose. After dehydration, the fire hose can be directly taken out and stored in a coiled state, avoiding the repetitive process of unfolding, drying, and then rolling it up for storage. Compared to manual washing, the fire hose washing equipment of this invention eliminates multiple repetitive steps such as unfolding and rolling, making the washing process simpler and less labor-intensive; at the same time, it avoids the use of large amounts of water for rinsing, thus saving water resources. Compared to conventional machine washing, the fire hose washing equipment of this invention has a simpler structure, operates on a similar principle to a washing machine, is more operable in the washing process, and can meet diverse washing requirements such as washing, rinsing, and dehydration. It also makes the entire washing process of fire hoses more convenient and efficient.

[0055] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0056] For example, in an alternative embodiment, the tube head storage structure 14 can be a boss, a fastening ring, or an adjustable elastic structure, as long as it can achieve tube head storage during the washing process. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0057] For example, in another alternative embodiment, the tray 12 can be a mesh woven structure, a rigid plastic structure with small holes, or a metal structure with small holes, as long as it can rise to the top of the washing tub 1 and filter mud and sand. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0058] For example, in another alternative embodiment, the impeller 11 and the washing shaft 31 can be fastened together by the impeller screw 111, or by snap-fit ​​connection, or they can be integrated. As long as the washing shaft 31 can drive the impeller 11 to rotate and achieve washing, these do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0059] For example, in another alternative embodiment, the box body may contain one outer barrel 5 or multiple outer barrels 5, as long as the box body serves as an overall support and covers the outer barrels 5. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0060] Finally, it should be noted that although this invention is described using a fire hose washing device as an example, the fire hose washing device of this invention can obviously also be applied to the washing of other similar items. For example, the tray 12 of this solution can also be used for washing ordinary programmable water pipes, rolled woven bags, curtains, etc., and the tray 12 can also be applied to washing machines and other equipment to meet the diverse washing needs of users.

[0061] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
