Description

Technical Field

[0001] This utility model relates to the technical field of fire hose cleaning equipment, specifically to a fire hose cleaning and decontamination device. Background Technology

[0002] Fire hoses are flexible hoses used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer surface covered with flax woven fabric. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spray pressure.

[0003] After firefighting operations, fire hoses are covered with a lot of ash, dirt and other stains. The traditional way to clean them is by hand, but this method is time-consuming, labor-intensive and the wastewater is difficult to recycle, resulting in water waste.

[0004] Therefore, this utility model provides a fire hose cleaning device to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fire hose cleaning device to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fire hose cleaning device includes a cleaning box and a lifting plate;

[0008] Cleaning box: The upper end of the cleaning box is equipped with a winding mechanism. The cleaning box is equipped with a partition to divide the inner cavity of the cleaning box into a return cavity and a water storage cavity. The lower parts of the return cavity and the water storage cavity are connected.

[0009] A filter plate is fixedly connected to the lower end of the reflux chamber;

[0010] The water storage chamber is fixedly connected to a base with an arc-shaped upper end, and the base is equipped with a water spray channel with an upward outlet.

[0011] Lifting plate: The lifting plate moves up and down inside the water storage chamber. Water supply components, spray pipes and arc-shaped plates are fixedly connected to the lifting plate.

[0012] The water supply component supplies water to the spray pipes and spray channels;

[0013] The curved plate is arc-shaped and covers the upper part of the base;

[0014] The outlet of the water spray pipe faces downwards and is located directly above the water spray channel;

[0015] Through the above technical solution, when the lifting plate rises, it drives the arc plate to move upward, which can hang the fire hose on the winding mechanism for winding, and place the fire hose between the arc plate and the base. When the lifting plate descends, the arc plate presses down on the fire hose, which firstly makes the fire hose soak in the water storage chamber, and secondly makes the arc plate and the base clamp the fire hose to scrape and wash the fire hose. The upper end of the base is set to be arc-shaped and the arc plate is arc-shaped, which can ensure that the fire hose is in close contact with the upper side of the base and the lower side of the arc plate.

[0016] The water supply unit supplies water from the return chamber into the spray channel and spray pipe, which serves two purposes: firstly, to flush the fire hoses, and secondly, to allow water from the storage chamber to flow into the return chamber from the bottom. The filter plate filters the return water, thus recycling the wastewater.

[0017] Preferably, the winding mechanism includes a motor, a disc wheel, a winding roller, an auxiliary roller, and a support frame. The support frame is fixed to the side of the cleaning box, and a motor is fixedly connected to the support frame. The output end of the motor rotates through the support frame and is fixed to the disc wheel. The winding roller and the auxiliary roller are fixedly connected to the disc wheel, and the winding roller is located at the center of the disc wheel.

[0018] Through the above technical solution, the motor drives the disc wheel to rotate, the disc wheel drives the winding roller to rotate and drives the auxiliary roller to rotate, and the fire hose is wound up when it is sandwiched between the winding roller and the auxiliary roller.

[0019] Preferably, the water supply assembly includes a suction pipe, a housing, a water pump, an outlet pipe, and a corrugated pipe. The housing is fixed to the upper end of the lifting plate, and the water pump is fixed inside the housing. The water pump has a suction pipe fixed to its inlet end, which passes through the housing and extends into the return chamber. The water pump has an outlet pipe fixed to its outlet end, and the other end of the outlet pipe has two branches. One branch connects to the spray pipe, and the other branch is fixedly connected to the corrugated pipe. The other end of the corrugated pipe is connected to the spray channel.

[0020] With the above technical solution, when the water pump is powered on, part of the water flows through the suction pipe, the water pump and the outlet pipe and then enters the spray pipe, while another part of the water flows through the suction pipe, the water pump and the corrugated pipe and then enters the spray channel, thus simultaneously supplying water to the spray pipe and the spray channel.

[0021] Preferably, a first friction brush is fixed on both sides of the upper end of the base, and a second friction brush is fixed on the lower side of both arc plates, with the first friction brush and the second friction brush corresponding vertically.

[0022] Through the above technical solution, the first friction brush and the second friction brush increase the friction with the fire hose, and clean both sides of the fire hose.

[0023] Preferably, the upper surface of the base is configured as an outer arc surface, and the central angle of the outer arc surface is greater than the central angle of the first friction brush and the second friction brush.

[0024] With the above technical solution, since the space between the water spray pipe and the water spray channel is small, the length of the first friction brush and the second friction brush is shortened, so that the space between the two first friction brushes on the left and right and the two second friction brushes on the left and right is increased. Firstly, this allows the water sprayed from the water spray pipe and the water spray channel to have enough space to flow out, reducing the water pressure. Secondly, it allows the dirt on the fire hose to have enough space to flow out with the water flow after being brushed off.

[0025] Preferably, the lower two corners of the lifting plate are each equipped with a second rotating wheel, the two arc-shaped plates are located between the two second rotating wheels, and the lower ends of the two second rotating wheels are lower than the lower ends of the arc-shaped plates.

[0026] With the above technical solution, two second rotating wheels replace the arc plate to press the fire hose downwards. When the fire hose moves, the second rotating wheels rotate, reducing friction and thus reducing wear on the fire hose.

[0027] Preferably, a water-squeezing mechanism is installed between the lifting plate and the upper end of the cleaning box;

[0028] The water squeezing mechanism includes a first clamping plate and a second clamping plate. The first clamping plate is fixed inside the upper end of the water storage chamber of the cleaning box, and the second clamping plate is fixed to the upper end of the lifting plate. The corners of the first clamping plate and the second clamping plate that are corresponding to each other and close to each other are rounded.

[0029] With the above technical solution, the fire hose is clamped between the first clamp and the second clamp. When the fire hose moves, the first clamp and the second clamp squeeze out the water in the fire hose, which speeds up the subsequent drying of the fire hose.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. By controlling the lifting and lowering of the lifting plate, the fire hose is pressed into the water storage chamber. This allows the fire hose to be immersed in the water storage chamber and the curved plate and base to clamp the fire hose. When the winding mechanism winds up the fire hose, it scrapes and washes the fire hose.

[0032] 2. The water supply assembly supplies water from the return chamber into the spray channel and spray pipe. This serves two purposes: firstly, it flushes the fire hoses, and secondly, it allows water from the storage chamber to flow into the return chamber from the bottom. The filter plate filters the return water, thus recycling the wastewater.

[0033] 3. The fire hose is clamped between the first and second clamps. When the fire hose moves, the first and second clamps squeeze out the water inside the fire hose, which speeds up the subsequent drying of the fire hose.

[0034] In summary, this device is equipped with a cleaning box to provide water storage and wastewater storage space for the entire cleaning process. The filter plate filters the wastewater, and the first and second friction brushes on the arc plate and base are responsible for physically scrubbing the surface of the fire hose. The water spray channel and water spray pipe physically rinse the surface of the fire hose. The winding mechanism realizes the automatic winding of the hose. During the winding process, the fire hose can be squeezed and dehydrated by the water squeezing mechanism to shorten the subsequent drying time.

[0035] This device can quickly remove stains from water hoses, significantly improving efficiency compared to manual cleaning. It can wind and dehydrate the cleaned water hoses, shortening drying time. At the same time, it can recycle wastewater, realizing water resource recycling. While ensuring cleaning effect, it significantly reduces water waste, combining cleaning efficiency with environmental benefits. Attached Figure Description

[0042] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0043] As attached Figure 1 - Appendix Figure 5 As shown, a fire hose cleaning device includes a cleaning box 2 and a lifting plate 6.

[0044] Cleaning Box 2: See Appendix Figure 1 and attached Figure 3 The upper end of the cleaning box 2 is equipped with a winding mechanism 7. The cleaning box 2 is equipped with a partition to divide the inner cavity of the cleaning box 2 into a return chamber 4 and a water storage chamber 5. The lower parts of the return chamber 4 and the water storage chamber 5 are connected. The return chamber 4 and the water storage chamber 5 are filled with water. An observation window 1 is provided on the side of the cleaning box 2. The observation window 1 is located on the side of the return chamber 4. The observation window 1 is made of transparent acrylic material and is used to observe the degree of dirt accumulation in the return chamber 4.

[0045] A filter plate 9 is fixedly connected to the lower end of the reflux chamber 4, as shown in the appendix. Figure 3 Water flows from bottom to top into the return chamber 4, and the filter plate 9 filters the sewage.

[0046] A sewage discharge pipe 14 passes through the bottom side of the reflux chamber 4, see Appendix. Figure 3 It is used to discharge sewage. An end cap 24 is threaded onto the end of the sewage discharge pipe 14 to seal the sewage discharge pipe 14.

[0047] See attached Figure 3 and attached Figure 4 A base 16 with an arc-shaped upper end is fixedly connected inside the water storage chamber 5. A water spray channel 15 with an upward-facing outlet is provided inside the base 16. The outlet of the water spray channel 15 is upward-facing and located in the middle of the upper end of the base 16. First friction brushes 17 are fixed on both sides of the upper end of the base 16. The water spray channel 15 is located between the two first friction brushes 17. The upper surface of the base 16 is set as an outer arc surface 20. (See attached diagram) Figure 5 Furthermore, the central angle of the outer arc surface 20 is greater than that of the first friction brush 17, which makes the distance between the two first friction brushes 17 greater than the outlet diameter of the water spray channel 15, thus creating a certain space between the two first friction brushes 17.

[0048] Lifting platform 6: See appendix Figure 1 Appendix Figure 3 and attached Figure 4 A track is provided on the partition between the water storage chamber 5 and the return chamber 4. The lifting plate 6 moves up and down through the track, so that the lifting plate 6 moves up and down through the water storage chamber 5. The upper end of the lifting plate 6 is integrally formed with a handle, which can be used to lift the lifting plate 6 upward. A water supply component, a water spray pipe 12 and two arc plates 19 are fixedly connected to the lifting plate 6. The water spray pipe 12 is located in the middle of the two arc plates 19. The two corners at the lower end of the lifting plate 6 are equipped with second rotating wheels 13.

[0049] The water supply component supplies water to the water spray pipe 12 and the water spray channel 15;

[0050] See attached Figure 4 The arc-shaped plate 19 is arc-shaped, and the lower center of the lifting plate 6 has an arc-shaped notch, allowing the upper end of the base 16 to be inserted into the arc-shaped notch. The two arc-shaped plates 19 cover the upper end of the base 16. A second friction brush 18 is fixed to the lower inner side of each of the two arc-shaped plates 19. The first friction brush 17 corresponds vertically to the second friction brush 18. The central angle of the outer arc surface 20 is larger than the central angle of the second friction brush 18. (See attached diagram). Figure 5 This creates a certain space between the two second friction brushes 18, with the two arc-shaped plates 19 located between the two second rotating wheels 13, and the lower ends of the two second rotating wheels 13 being lower than the lower ends of the arc-shaped plates 19.

[0051] See attached Figure 3 and attached Figure 4 The outlet of the water spray pipe 12 faces downwards. Since the water spray channel 15 is located in the middle of the upper end of the base 16 and the water spray pipe 12 is located in the middle of the two arc plates 19, the water spray pipe 12 is located directly above the water spray channel 15.

[0052] In this embodiment, refer to the appendix. Figure 1 The winding mechanism 7 includes a motor 71, a disc wheel 72, a winding roller 73, an auxiliary roller 74, and a support frame 75. The support frame 75 is fixed to the side of the cleaning box 2. The motor 71 is fixedly connected to the support frame 75. The input end of the motor 71 is electrically connected to an external mains power supply. The output end of the motor 71 rotates through the support frame 75 and is fixedly connected to the disc wheel 72. The winding roller 73 and the auxiliary roller 74 are fixedly connected to the disc wheel 72. The winding roller 73 is located at the center of the disc wheel 72.

[0053] The working method of the winding mechanism 7 is as follows: the fire hose is passed through the winding roller 73 and the auxiliary roller 74. After the motor 71 is powered on, it drives the disc wheel 72 to rotate. The disc wheel 72 drives the winding roller 73 to rotate. The disc wheel 72 drives the auxiliary roller 74 to rotate around the winding roller 73. Then the auxiliary roller 74 pushes the fire hose to wind around the winding roller 73, and the fire hose can be wound up.

[0054] In this embodiment, refer to the appendix. Figure 3 The water supply assembly includes a suction pipe 10, a housing 11, a water pump 21, a water outlet pipe 22, and a corrugated pipe 23. The housing 11 is fixed to the upper end of the lifting plate 6. The water pump 21 is fixed inside the housing 11. The input end of the water pump 21 is electrically connected to an external mains power supply. The water inlet end of the water pump 21 is fixed with the suction pipe 10. The suction pipe 10 passes through the housing 11 and extends into the return chamber 4. The water outlet end of the water pump 21 is fixed with the water outlet pipe 22. The other end of the water outlet pipe 22 is divided into two branches. One branch is connected to the spray pipe 12, and the other branch is fixedly connected to the corrugated pipe 23. The other end of the corrugated pipe 23 is connected to the spray channel 15.

[0055] The water supply assembly operates as follows: when the water pump 21 is powered on, a portion of the water flows sequentially through the return chamber 4, the suction pipe 10, the water pump 21, and the outlet pipe 22 before entering the spray pipe 12; another portion of the water flows sequentially through the return chamber 4, the suction pipe 10, the water pump 21, the outlet pipe 22, and the corrugated pipe 23 before entering the spray channel 15.

[0056] In this embodiment, refer to the appendix. Figure 1 and attached Figure 4 A water-squeezing mechanism 8 is installed between the upper end of the lifting plate 6 and the cleaning box 2;

[0057] The water squeezing mechanism 8 includes a first clamping plate 81 and a second clamping plate 82. The first clamping plate 81 is fixed inside the upper end of the water storage chamber 5 of the cleaning box 2, and the second clamping plate 82 is fixed to the upper end of the lifting plate 6. The corners of the first clamping plate 81 and the second clamping plate 82 that are corresponding to each other and close to each other are rounded.

[0058] The working principle of the water squeezing mechanism 8 is as follows: after the lifting plate 6 moves down, the first clamping plate 81 and the second clamping plate 82 move closer to each other, and the fire hose is clamped between the first clamping plate 81 and the second clamping plate 82, squeezing out the water stains on the fire hose.

[0059] In this embodiment, refer to the appendix. Figure 1 and attached Figure 4 The first rotating wheel 3 is located inside the upper end of the cleaning box 2 and rotates through a rotating shaft. The first rotating wheel 3 and the first clamping plate 81 are respectively installed on the left and right opposite sides of the water storage chamber 5.

[0060] The working principle of this device is as follows:

[0061] Pour water into the cleaning tank 2 through the top opening until the water level submerges the spray pipe 12 and the lower end of the suction pipe 10. Lift the lifting plate 6 upwards, and pass the fire hose over the top of the first rotating wheel 3, below the second rotating wheel 13 on the right, below the second friction brush 18 on the right, below the spray pipe 12, below the second friction brush 18 on the left, below the second rotating wheel 13 on the left, and below the second clamping plate 82, then insert it between the winding roller 73 and the auxiliary roller 74. Press the lifting plate 6 downwards so that the first friction brush 17 and the second friction brush 18 clamp the fire hose. The hose reel in the hose and the winding mechanism 7 begins to wind it up. At this time, the first friction brush 17 and the second friction brush 18 scrub the fire hose, the water spray pipe 12 and the water spray channel 15 rinse the fire hose, and the first clamping plate 81 and the second clamping plate 82 squeeze out the water. During this process, the water flows between the water storage chamber 5, the return chamber 4 and the water supply assembly. When the water flows through the return chamber 4, the filter plate 9 filters the water. After cleaning, the end cover 24 is opened so that the water is discharged from the sewage discharge pipe 14, while the water in the return chamber 4 flows downward to backwash the filter plate 9.
