Description

Technical Field

[0001] This utility model relates to the technical field of hose cleaning devices, specifically to a hose cleaning device for a fire drainage truck type 300. Background Technology

[0002] In fire and flood drainage operations, the 300-type water hose, as the core water delivery component of the fire and flood drainage vehicle, is frequently exposed to impurities such as mud, sewage, and corrosive liquids. If it is not cleaned in time after use, impurities will adhere to the inner and outer walls of the hose: the mud and sand remaining on the inner wall can easily block the water delivery channel and reduce the water delivery efficiency; the dirt and corrosive substances on the outer wall will accelerate the aging of the hose rubber, shorten its service life, and may even cause water leakage due to hose damage in the next operation, affecting the efficiency of flood drainage and disaster relief.

[0003] Currently, cleaning of the 300-type water hose is primarily done manually. This requires one person to hold a high-pressure water gun to rinse the hose surface, while 1-2 others work together to unfold and rotate the hose, ensuring both the inner and outer walls are cleaned. Due to the large diameter (approximately 300mm) and length (typically 20-50 meters) of the 300-type hose, the manual unfolding and rewinding process is cumbersome, with each hose taking well over an hour to clean, resulting in low overall efficiency. For fire and rescue teams, multiple hoses often need to be cleaned in batches after disasters, and manual cleaning methods are insufficient to meet the need for rapid equipment recovery, while also requiring significant manpower and increasing maintenance costs. Therefore, we propose a 300-type water hose cleaning device for fire and drainage vehicles. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3This utility model provides a technical solution: a fire hose cleaning device for a 300-type fire drainage truck, including a wastewater tank 1, a cleaning tank 11 fixedly installed on the top surface of the wastewater tank 1, the front side of the cleaning tank 11 being connected to the outside, a through hole 14 provided on the top plate of the cleaning tank 11, a booster pump 2 fixedly installed on the top surface of the cleaning tank 11, a three-way pipe 21 fixedly installed at the outlet end of the booster pump 2, a three-way valve 22 provided on the three-way pipe 21, a hose connector holder 23 fixedly installed on the other pipe body of the three-way pipe 21 for engaging with the hose connector, and the remaining pipe body of the three-way pipe 21... The washing tank 11 is equipped with a conveying pipe 24 for rinsing the surface of the hose. Inside the washing tank 11, there are two symmetrical brush rollers 15. The brush rollers 15 are driven to rotate by a motor installed on the rear side plate of the washing tank 11. Two symmetrical support plates 3 are fixedly installed on the top surface of the washing tank 11. The support plates 3 are rotatably connected to the conveying rollers 30 for conveying the hose. The conveying rollers 30 are driven by a drive motor 32 and a gear 31, so that the booster pump 2 and the brush rollers 15 work together to clean the inner and outer walls of the hose. The conveying rollers 30 automatically convey the hose, saving manpower and making it convenient to use.

[0031] like Figure 1 and Figure 2 As shown, the upper, lower, and front sides of the through hole 14 are all connected to the outside. A drain pipe 10 is fixedly installed on the side of the bottom of the wastewater tank 1, allowing staff to easily take out and put in the water hose from the through hole 14. The drain pipe 10 can discharge the cleaning wastewater collected in the wastewater tank 1 in a concentrated manner, which is convenient for subsequent unified treatment, avoids wastewater accumulation that could cause pollution to the device, and improves the convenience of operation and environmental protection.

[0032] In this embodiment, a front insertion gap 12 is provided between the top of the front body of the wastewater tank 1 and the cleaning tank 11. The front insertion gap 12 is used for the insertion of water hoses, so that long and large-diameter 300-type water hoses can be directly inserted into the cleaning tank 11 through the front insertion gap 12, which greatly reduces the difficulty of inserting water hoses, saves preparation time, and improves the ease of use of the device.

[0033] like Figure 1 and Figure 2 As shown, water baffles 13 are hinged to the front sides of both the left and right sides of the cleaning tank 11. A transparent panel 131 is provided on the water baffles 13 so that closing the water baffles 13 during the cleaning process can effectively prevent the rinsing water from splashing outwards and keep the working environment dry and clean. The transparent panel 131 allows the staff to observe the cleaning status of the water hose in the cleaning tank 11 in real time and judge the cleaning effect without opening the water baffles 13. It combines the anti-splash function with the convenience of observation. The water baffles 13 are equipped with a door lock to prevent the water baffles 13 from being opened easily.

[0034] like Figure 1As shown, an inlet pipe 20 is fixedly installed at the water inlet end of the booster pump 2, and a U-shaped pipe 25 is fixedly installed at the end of the delivery pipe 24. Multiple flushing nozzles 26 are fixedly installed on the inner side of the pipe on both the left and right sides of the U-shaped pipe 25. The flushing nozzles 26 face one side of the water hose, so that the inlet pipe 20 can stably deliver clean water to the booster pump 2. The U-shaped pipe 25 is distributed around the water hose, and the flushing nozzles 26 can spray water from both the left and right sides of the water hose simultaneously, fully covering the surface of the water hose, ensuring that there are no dead corners on the outer wall of the water hose, and improving the cleanliness of the water hose surface.

[0035] Specifically, a belt-passing gap 27 is provided between the two sets of rinsing nozzles 26 on the left and right sides. The rinsing nozzles 26 are located above the brush roller 15, so that the water belt can pass smoothly through the belt-passing gap 27 without being blocked by the rinsing nozzles 26. The rinsing nozzles 26 perform a more thorough rinsing operation on the surface of the water belt above the brush roller 15, further improving cleaning efficiency and quality.

[0036] Furthermore, gears 31 are fixedly installed at the ends of the conveying rollers 30, and the two gears 31 mesh with each other. The drive motor 32 is coaxially installed at the end of one of the conveying rollers 30 and is fixedly installed on the corresponding support plate 3. After the drive motor 32 is started, it drives the two conveying rollers 30 to rotate synchronously through the meshing gears 31, so as to realize the conveying operation of the water belt.

[0037] It is worth noting that the two ends of the water hose are equipped with connectors, which can be snapped together with the water hose connector holder 23. Both the connectors on the water hose and the water hose connector holder 23 are existing conventional technologies and will not be described in detail here. In addition, the distance between the two conveying rollers 30 is adapted to the thickness of the water hose and is less than the thickness of the connector on the water hose, so that the water hose can pass between the two conveying rollers 30 and perform the water hose conveying operation as the conveying rollers 30 rotate.

[0038] Finally, it should be noted that the booster pump 2, motor, drive motor 32, corresponding control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation.

[0039] When using the fire hose cleaning device of the 300 type fire drainage vehicle of this utility model, open the water baffle 13 of the cleaning tank 11, put the 300 type hose into the cleaning tank 11 through the front insertion gap 12 between the waste water tank 1 and the cleaning tank 11, so that the hose passes through the threading gap 27 between the two brush rollers 15 and the flushing nozzle 26, and then passes out through the exit hole 14. Then, the connector at the top of the hose is clamped on the hose connector clamp 23. Turn the three-way valve 22 until the booster pump 2 is connected to the hose connector clamp 23. At this time, the staff will neatly arrange the hoses piled in the waste water tank 1, then connect the liquid inlet pipe 20 to the external cleaning water source, start the booster pump 2, and realize the internal flushing operation of the hose. The flushing wastewater enters the waste water tank 1.

[0040] After the internal rinsing of the water hose is completed, remove the connector at the end of the water hose from the water hose connector holder 23, and then clamp the water hose between the upper and lower conveyor rollers 30. Close the water baffle 13, start the drive motor 32, and drive the conveyor rollers 30 to rotate synchronously through the meshing gear 31 to realize the conveying of the water hose. During the conveying of the water hose, turn the three-way valve 22 to connect the booster pump 2 with the rinsing nozzle 26. At this time, the rinsing nozzle 26 of the U-shaped tube 25 rinses the surface of the water hose from both sides. The brush roller 15 below is driven by the motor to rotate and brush away stubborn dirt. The cleaning wastewater flows into the wastewater tank 1 and is finally discharged through the sewage pipe 10. The cleaning status can be observed through the transparent plate 131.

[0041] After the water hose is cleaned inside and out, remove the water hose from the brush roller 15, the belt threading gap 27 and the threading hole 14, and use a transfer tool to transfer it to an outdoor drying area or other drying area for drying.
