Description

Technical Field

[0001] This utility model relates to the field of fire hose cleaning technology, and in particular to a hose cleaning machine. Background Technology

[0002] Currently, after firefighting and rescue operations, water hoses are prone to accumulating large amounts of mud and stains due to the working environment. These mud and stains are complex in composition, containing not only soil and sand from the ground, but also various chemicals produced by combustion, oil, and other debris from the fire scene. They adhere tightly to the surface of the water hoses, forming a stubborn layer of grime.

[0003] If these hoses are not cleaned promptly or thoroughly, the residual mud and stains will become "invisible killers." In damp environments, they provide an ideal breeding ground for mold. Mold will quickly spread and grow on the surface of the hoses, gradually eroding their material. Over time, the hoses will rot, their internal fiber structure will be damaged, and their strength will be significantly reduced, thus greatly shortening their lifespan. This not only increases the equipment procurement costs for fire departments but may also affect the efficiency of firefighting and rescue operations at critical moments due to hose damage.

[0004] When the existing hose cleaning device is started, the hose enters the cleaning area. At this time, the upper and lower sets of brush rollers begin to operate synchronously. The upper brush roller is in close contact with the upper surface of the hose. During the high-speed rotation, the dense bristles on its surface act like countless tiny cleaning brushes, powerfully scrubbing away the mud, stains and other impurities attached to the surface of the hose.

[0005] During the cleaning process, the mud and dirt generated by the brush rollers on the upper surface of the hose flow downwards with the rinsing water. Due to certain limitations in the structural design of the device, and the lack of effective diversion and isolation measures, this water containing mud and dirt can easily flow directly into the lower surface of the hose during the flow process.

[0006] When this water containing impurities comes into contact with the lower surface of the hose, the surface, which has already undergone preliminary cleaning or is not yet severely contaminated, is instantly covered with mud and grime, causing secondary pollution. This secondary pollution significantly reduces the cleaning effectiveness of the hose, making it difficult to achieve the hose cleanliness standards that were originally expected to be met with a single cleaning.

[0013] Furthermore, the cleaning tank has a water hose inlet and a water hose outlet on one end of its wall, and the side wall of the cleaning tank has slots distributed along the upper brush roller, lower brush roller, upper guide roller, lower guide roller and reversing guide roller. The lower end of the slot is connected to the water hose inlet and the upper end of the slot is connected to the water hose outlet. The water hose can be easily put into the cleaning tank through the slots.

[0014] Furthermore, the transmission assembly includes a belt drive mechanism, a drive gear, a driven gear, and a transmission gear. The two upper brush rollers and the two lower brush rollers are connected by the belt drive mechanism. One upper brush roller is fixedly connected to the gear hole of the drive gear, and one lower brush roller is fixedly connected to the gear hole of the driven gear. The outer wall of the cleaning tank is rotatably connected to the transmission gear through a rotating shaft.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 , 2 As shown in Figures 4 and 5, this utility model includes a cleaning tank 1 and a brushing mechanism 2.

[0035] The cleaning tank 1 is equipped with a brushing mechanism 2, which is connected to the drive mechanism via a transmission assembly 4. The drive mechanism can drive the brushing mechanism 2 to work via the transmission assembly 4.

[0036] like Figure 3 As shown, the brushing mechanism 2 includes an upper brush roller 21 and a lower brush roller 23. The roller shafts at both ends of the upper brush roller 21 and the lower brush roller 23 are rotatably connected to the cavity of the cleaning tank 1. The upper brush roller 21 is installed above the lower brush roller 23. The upper brush roller 21 and the lower brush roller 23 are connected to the drive mechanism through the transmission assembly 4. The drive mechanism can drive the upper brush roller 21 and the lower brush roller 23 to rotate through the transmission assembly 4. The rotation directions of the upper brush roller 21 and the lower brush roller 23 are opposite.

[0037] A partition plate 11 is installed in the middle of the cleaning tank 1. The partition plate 11 separates the upper brush roller 21 and the lower brush roller 23 into two cavities. The partition plate 11 is arranged at an angle in the cleaning tank 1. A strip-shaped through hole is provided between the higher end of the partition plate 11 and the inner end wall of the cleaning tank 1 to facilitate the passage of the water hose. A drain pipe 12 is provided at the lower end of the partition plate 11. The cavity of the drain pipe 12 connects the upper and lower cavities of the cleaning tank 1. The drain pipe 12 can discharge the sewage in the upper cavity into the lower cavity. A drain pipe 13 is provided at the lower end of the cleaning tank 1. The cavity of the drain pipe 13 is connected to the lower cavity of the cleaning tank 1.

[0038] The drain pipe 12 is located at the corner of the partition plate 11. The lower end of the drain pipe 12 is close to the bottom wall of the cleaning tank 1, which can prevent the water discharged from the upper cavity from splashing onto the water belt in the lower cavity.

[0039] In this embodiment, the cleaning box 1 is equipped with two upper brush rollers 21 and two lower brush rollers 23. The side wall of the cleaning box 1 is provided with a rotating through hole. The roller shafts of the two upper brush rollers 21 and the two lower brush rollers 23 pass through the corresponding rotating through holes and are connected to the rotating through holes by a rotating sealing ring.

[0040] The two lower brush rollers 23 are provided with lower guide rollers 26 at the middle position and at both ends of the two lower brush rollers 23, and upper guide rollers 25 are provided at the middle position and at both ends of the two upper brush rollers 21. A reversing guide roller 24 is provided between the upper guide roller 25 at one end of the upper brush roller 21 and the upper brush roller 21. The two ends of the upper guide roller 25, the lower guide roller 26 and the reversing guide roller 24 are rotatably connected to the inner wall of the cleaning tank 1.

[0041] The cleaning tank 1 has a water hose inlet and a water hose outlet on one end of its wall. The side wall of the cleaning tank 1 has slots distributed along the upper brush roller 21, lower brush roller 23, upper guide roller 25, lower guide roller 26 and reversing guide roller 24. The lower end of the slot is connected to the water hose inlet and the upper end of the slot is connected to the water hose outlet. The water hose can be easily put into the cleaning tank 1 through the slots.

[0042] like Figure 5 and 6 As shown, the transmission assembly 4 includes a belt drive mechanism 44, a driving gear 41, a driven gear 43, and a transmission gear 42. The two upper brush rollers 21 and the two lower brush rollers 23 are respectively connected by the belt drive mechanism 44. One upper brush roller 21 is fixedly connected to the gear hole of the driving gear 41, and one lower brush roller 23 is fixedly connected to the gear hole of the driven gear 43. The outer wall of the cleaning tank 1 is rotatably connected to the transmission gear 42 through a rotating shaft.

[0043] The driving gear 41 meshes externally with the transmission gear 42, and the transmission gear 42 meshes externally with the driven gear 43. The driving mechanism is fixedly connected to the driving gear 41, thereby enabling the upper brush roller 21 and the lower brush roller 23 to rotate in opposite directions.

[0044] The cleaning tank 1 is fixedly connected to the transmission box 14. The transmission box 14 is equipped with a transmission assembly 4, and the water turbine pump 3 is fixedly installed on the outside of the transmission box 14.

[0045] like Figure 8 As shown, the upper brush roller 21 and the lower brush roller 23 have a central hole on their roller shafts. An inner tube 22 is installed inside the central hole. The inner tube 22 has a cavity with one end open. The outer wall of the inner tube 22 is rotatably sealed to the inner wall of the central hole. The upper part of the inner tube 22 has two sets of spray holes evenly distributed along the axis. The two sets of spray holes are symmetrically distributed and face the lower surface of the upper water belt. The water flow sprayed from the two sets of spray holes at the upper end can wash the lower surface of the water belt. The lower part of the inner tube 22 has a set of spray holes evenly distributed along the axis. The spray holes at the lower end of the inner tube 22 are inclined downwards. The water flow sprayed from the spray holes at the lower end can clean the brush roller.

[0046] In the optimized solution, a nozzle is installed in the spray hole at the lower end of the inner tube 22.

[0047] One end of the inner tube 22 is fixed to the outer wall of the cleaning tank 1 by a connecting plate 27. The opening of the inner tube 22 is connected to the water pump through a connecting pipe. The water pump can inject water into the inner tube 22 and spray it out from the spray hole.

[0048] The outer walls of the upper brush roller 21 and the lower brush roller 23 are respectively provided with multiple sets of arc-shaped through holes evenly distributed along the circumference. The arc-shaped through holes correspond to the spray holes of the inner tube 22. When the upper brush roller 21 or the lower brush roller 23 rotates, when the arc-shaped through holes on the brush rollers coincide with the spray holes on the inner tube 22, water can be sprayed out to rinse the water belt.

[0049] like Figure 7 As shown, in the optimized scheme, the two sets of adjacent arc-shaped through holes of the upper brush roller 21 and the lower brush roller 23 are staggered, which enables water to be sprayed out continuously when the upper brush roller 21 and the lower brush roller 23 rotate.

[0050] like Figure 9 and 10 As shown, in this embodiment, the water pump and the drive mechanism are an integral water turbine pump 3. The water turbine pump 3 includes a pump casing 31, an impeller 32 and an output shaft 35. The pump casing 31 has a cavity inside, and the impeller 32 is installed in the cavity of the pump casing 31. The output shaft 35 is fixedly installed at the center of the impeller 32. One end of the output shaft 35 is rotatably connected to the pump casing 31, and the other end passes through the through hole on the pump casing 31 and is connected to the drive gear 41.

[0051] The pump casing 31 has an inlet at one end and an outlet at the other end. The inlet and outlet are located on opposite sides of the cavity and are connected to the cavity of the pump casing 31. The impeller 32 separates the inlet and outlet of the pump casing 31. The inlet is connected to the water tank of the fire truck in sequence through a quick connector and a water pipe. The outlet is connected to the opening of the inner pipe 22 through a connecting pipe. After the water enters through the inlet of the pump casing 31, it drives the impeller 32 to rotate and finally flows out through the outlet of the pump casing 31.

[0052] The inlet and outlet of the pump casing 31 are connected by a connecting hole. A sealing sleeve 33 is fixedly installed at one end of the connecting hole near the inlet. The sealing sleeve 33 has a cavity with one end open. The other end of the sealing sleeve 33 has a through hole that connects to the cavity. A piston 34 is installed inside the cavity of the sealing sleeve 33. One end of the piston 34 is connected to the end wall of the connecting hole by a compression spring. The compression spring presses the piston 34 tightly against the end wall of the cavity of the sealing sleeve 33, blocking the through hole on the end wall of the sealing sleeve 33.

[0053] The piston 34 has multiple circumferentially distributed notches on its outer edge. When the water pressure at the inlet is high, the water flow can push the piston 34, causing the piston 34 to leave the through hole on the end wall of the sealing sleeve 33, so that the outlet and the inlet are connected, allowing a portion of the water to flow directly from the inlet to the outlet.

[0054] The operating procedure is as follows: When using this utility model, the water hose enters the cavity of the cleaning tank 1 through the water hose inlet. The water hose passes sequentially around the lower guide roller 26 and the lower brush roller 23, so that the lower surface of the water hose contacts the upper part of the bristles of the lower brush roller 23. The water hose passes through the strip-shaped through hole of the partition plate 11 into the upper cavity, and passes around the upper guide roller 25, the deflecting guide roller 24 and the upper brush roller 21. Through the deflecting guide roller 24, the lower surface of the water hose contacts the upper part of the bristles of the upper brush roller 21, moving towards... Water is introduced into the water turbine pump 3, and the water flow drives the impeller 32 to rotate. The impeller 32 drives the output shaft 35 to rotate, and the output shaft 35 drives the upper brush roller 21 and the lower brush roller 23 to rotate through the transmission assembly 4, so that the upper brush roller 21 and the lower brush roller 23 can perform brushing. During the brushing process, the water flow from the water turbine pump 3 enters the inner tube 22 through the connecting pipe. When the arc-shaped through hole on the brush roller coincides with the spray hole on the inner tube 22 during the rotation of the upper brush roller 21 or the lower brush roller 23, water can be sprayed out to rinse the water belt.

[0055] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
