Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a fire-fighting water pipe cleaning device. Background Technology

[0002] Fire water pipes are pipes used in fire protection to connect fire equipment and materials and to transport water for fire extinguishing. Due to special requirements, fire water pipes have special requirements for thickness and material, and are painted red. After use, fire water pipes will have a lot of mud and sand on their surface, so cleaning equipment is needed to clean them. However, traditional fire water pipe cleaning equipment is not effective and has low cleaning efficiency.

[0003] A search revealed that patent CN202220010156.8 discloses a fire hose cleaning device. The device, during use, involves setting up a base with support platforms fixedly installed on both sides of the top back of the base. A stepper motor is fixedly installed on the top of the support platforms, and a take-up roller is fixedly installed on the output shaft of the stepper motor. The surface of the take-up roller is wound with the fire hose body. A water tank is fixedly installed on the top of the base, and columns are fixedly installed around the top of the water tank. A top plate is fixedly installed on the top of the columns, and an electric push rod is fixedly installed at the bottom of the top plate. A stabilizing plate is fixedly installed at the output end of the electric push rod. This utility model comprises a base, water tank, take-up roller, fire hose body, column, top plate, electric push rod, stabilizing plate, cleaning brush, guide roller, positioning plate, support platform, stepper motor, positioning bearing, and stabilizing bearing. It solves the problems of poor performance and low cleaning efficiency of traditional fire hose cleaning devices. However, this device can only clean one side of the fire hose body. Since only one side of the fire hose can be cleaned, the other side may still retain stains or impurities, leading to unsatisfactory cleaning results and failing to meet strict cleaning standards. If both sides of the fire hose need to be cleaned, the hose needs to be manually flipped or the device position adjusted, which not only increases the complexity of operation but may also reduce cleaning efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fire-fighting water pipe cleaning device, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A fire hose cleaning device for fire protection includes a base plate on which a water tank is installed;

[0007] The pool has side walls on both sides, and a rotating seal is embedded in the side wall. A fixed shaft is rotatably installed on the side wall through the rotating seal. A coil spring is installed on the fixed shaft. A pad is installed on the bottom plate, and a fixed block is installed on the pad. The fixed shaft and the fixed block fix the two ends of the coil spring respectively.

[0008] The fixed shaft is located at one end in the water tank and has a turntable. The turntable has two brush rollers and a water hose body passes between the two brush rollers. The two brush rollers are in contact with the two sides of the coil spring. The water tank is filled with cleaning liquid and the brush rollers are located below the surface of the cleaning liquid.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the fixed shaft drives the turntable to deflect through the elastic force of the coil spring, thereby providing a pre-tightening force to the two brush rollers on the turntable, which press against the water hose body.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The spring force ensures that the brush roller remains in close contact with the hose body, providing stable and appropriate pressure for cleaning. This pressure can adapt to hoses of different specifications and materials, preventing uneven cleaning pressure due to differences in hose diameter, thickness, or hardness, thus improving the consistency and stability of the cleaning effect. Furthermore, due to the spring's elasticity, pressure on the brush roller is maintained even after prolonged use, reducing the decline in cleaning effect caused by component wear and extending the effective service life of the equipment.

[0013] Furthermore, the pool is provided with a first guide roller and a second guide roller, with the first guide roller located above the second guide roller.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The arrangement of the first and second guide rollers allows the water hose to enter and pass through the water tank in an orderly manner. The layout of the first guide roller being above and the second guide roller being below guides the water hose to enter the water tank from above and then gradually penetrate below the level of the cleaning solution. This ensures that the water hose is fully immersed in the cleaning solution, guaranteeing sufficient contact between the water hose and the cleaning solution. This provides a good soaking foundation for subsequent cleaning work, helps to dissolve and loosen stubborn stains on the surface of the water hose, and prepares it for the brushing work of the brush roller, thereby improving cleaning efficiency and cleaning effect.

[0016] Furthermore, the water hose body is introduced into the water tank through the first guide roller, and then guided into the water tank below the liquid level through the second guide roller, and the two sides of the water hose body are brushed by the brush roller.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] By guiding the hose body with the first and second guide rollers, the movement trajectory of the hose body within the water tank can be controlled, ensuring that the hose body enters and passes through the cleaning solution along a suitable path. This prevents the hose body from tangling or accumulating in the water tank, which would affect the cleaning operation. Simultaneously, this orderly introduction method allows both sides of the hose body to be fully immersed in the cleaning solution. Following this, the brush rollers scrub the sides, providing a comprehensive cleaning of the hose body. This continuous operation from immersion to scrubbing effectively removes dirt, oil, dust, and other impurities from the hose body's surface, improving the thoroughness and completeness of the cleaning.

[0019] Furthermore, the ends of the first guide roller, the second guide roller, and the brush roller are provided with stops, and the water hose body is limited on the first guide roller, the second guide roller, and the brush roller by the stops.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The baffles prevent the hose from slipping or shifting off the first guide roller, second guide roller, and brush roller during the cleaning process, ensuring stable hose transport and cleaning within the equipment. This avoids uneven cleaning or unwashed areas due to hose misalignment, guaranteeing the continuity and reliability of the cleaning operation. Furthermore, the baffles reduce the risk of equipment malfunctions, improving safety and ease of operation. They also reduce the frequency of manual adjustments needed due to hose misalignment, lowering labor costs and increasing automation.

[0022] This utility model provides a fire hose cleaning device. It has the following beneficial effects:

[0023] The fixed shaft and the fixed block are connected by a coil spring. The spring force drives the turntable to deflect, which can provide the brush roller with the pre-tightening force pressing on the water hose body. There is no need to frequently adjust the pressure between the brush roller and the water hose manually. This can ensure that the brush roller always brushes the water hose with appropriate pressure, improve the cleaning effect, and can also adapt to water hoses of different thicknesses or materials, thus having good versatility.

[0024] Two brush rollers are positioned on a turntable below the cleaning solution surface. The hose body passes between the two brush rollers, allowing for simultaneous brushing of both sides of the hose body. This effectively removes stains and impurities from the hose, resulting in high cleaning efficiency. A first guide roller and a second guide roller are installed inside the water tank. The hose is guided into the tank via the first guide roller and then guided below the liquid level via the second guide roller. This ensures a proper flow of the hose within the tank, allowing it to be fully immersed in the cleaning solution. Combined with the brush rollers, this further enhances the cleaning effect.

[0025] The first guide roller, the second guide roller, and the brush roller are equipped with stops at their ends. The water hose body is limited on these rollers by the stops, which can prevent the water hose from shifting or slipping during the cleaning process, ensuring the stability and continuity of the cleaning process, ensuring that the cleaning work can be carried out smoothly, and also avoiding the problem of incomplete cleaning due to the water hose shifting position.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0036] Example 1

[0037] A fire hose cleaning device includes a base plate 3, a water tank 2 mounted on the base plate 3, side walls 201 on both sides of the water tank 2, a rotating seal 202 embedded in the side walls 201, a fixed shaft 402 rotatably mounted on the side walls 201 via the rotating seal 202, a coil spring 5 mounted on the fixed shaft 402, a pad 4 mounted on the base plate 3, and a fixing block 401 mounted on the pad 4. The fixed shaft 402 and the fixing block 401 respectively fix the two ends of the coil spring 5. The fixed shaft 402 drives the turntable 6 to deflect through the elastic force of the coil spring 5, thereby providing a pre-tightening force to the two brush rollers 601 on the turntable 6 pressing against the hose body 1. The elastic force of the coil spring 5 can ensure that the brush rollers 601 are always tightly attached to the hose body 1, providing stable and appropriate pressure for cleaning. This pressure can adapt to hoses of different specifications and materials, and will not cause uneven cleaning pressure due to differences in the diameter, thickness or hardness of the hose during the cleaning process, thereby improving the consistency and stability of the cleaning effect. Meanwhile, due to the elasticity of the coil spring 5, it can maintain pressure on the brush roller 601 even after long-term use, reducing the decline in cleaning effect caused by component wear and extending the effective service life of the equipment.

[0038] Example 2

[0039] To facilitate simultaneous brushing of both sides of the water hose body 1, for example, as follows: Figures 1 to 4As shown, this utility model also includes: a turntable 6 is provided at one end of the fixed shaft 402 located in the water tank 2, and two brush rollers 601 are provided on the turntable 6. A water hose body 1 is inserted between the two brush rollers 601, and the two brush rollers 601 are respectively in contact with the two side surfaces of the coil spring 5. The water tank 2 is filled with cleaning liquid, and the brush rollers 601 are located below the liquid surface of the cleaning liquid. A first guide roller 7 and a second guide roller 8 are provided in the water tank 2, and the first guide roller 7 is located above the second guide roller 8. The arrangement of the first guide roller 7 and the second guide roller 8 allows the water hose body 1 to enter and pass through the water tank 2 in an orderly manner. The layout of the first guide roller 7 being above and the second guide roller 8 being below can guide the water hose body 1 to enter the water tank 2 from the top first, and then gradually penetrate below the liquid level of the cleaning liquid, so that the water hose body 1... The hose body 1 is fully immersed in the cleaning solution, ensuring sufficient contact between the hose body 1 and the cleaning solution. This provides a good soaking foundation for subsequent cleaning work, helps to dissolve and loosen stubborn stains on the surface of the hose body 1, and prepares it for the brushing work of the brush roller 601, thereby improving cleaning efficiency and cleaning effect. The hose body 1 is introduced into the water tank 2 through the first guide roller 7, and then guided into the water tank 2 below the liquid level through the second guide roller 8. The two sides of the hose body 1 are brushed by the brush roller 601. By guiding the hose body 1 through the first guide roller 7 and the second guide roller 8, the movement trajectory of the hose body 1 in the water tank 2 can be controlled, ensuring that the hose body 1 enters and passes through the cleaning solution through a suitable path, avoiding the hose body 1 from getting tangled or accumulating in the water tank 2, which would affect the cleaning operation. Meanwhile, this orderly introduction method allows both sides of the hose body 1 to be fully immersed in the cleaning solution. After being brushed by the brush roller 601, the hose body 1 can be cleaned in all directions. The continuous operation from immersion to brushing can effectively remove dirt, oil stains, dust and other impurities from the surface of the hose body 1, improving the comprehensiveness and thoroughness of the cleaning. The ends of the first guide roller 7, the second guide roller 8 and the brush roller 601 are equipped with stop blocks 602. The hose body 1 is limited on the first guide roller 7, the second guide roller 8 and the brush roller 601 by the stop blocks 602. The setting of the stop blocks 602 can prevent the hose body 1 from slipping or shifting off the first guide roller 7, the second guide roller 8 and the brush roller 601 during the cleaning process, ensuring the stable transmission and cleaning of the hose body 1 in the equipment, avoiding the problem of uneven cleaning or some areas not being cleaned due to the positional displacement of the hose body 1, and ensuring the continuity and reliability of the cleaning work. In addition, the presence of the stop 602 reduces the risk of malfunctions during equipment operation, improves equipment safety and ease of operation, reduces the frequency of manual adjustment required due to abnormal position of the water hose body 1, reduces manual operation costs, and improves the automation level of the equipment.

[0040] Working principle:

[0041] The fixed shaft 402 and the fixed block 401 of the equipment respectively fix the two ends of the coil spring 5. The fixed shaft 402 is rotatably mounted on the side wall 201 of the water tank 2 through the rotating seal 202. Under the action of its own elastic force, the coil spring 5 will drive the fixed shaft 402 to rotate, and the turntable 6 mounted on the fixed shaft 402 will deflect accordingly. Since there are two brush rollers 601 mounted on the turntable 6, and the brush rollers 601 are in contact with the two side surfaces of the coil spring 5, the elastic force of the coil spring 5 will indirectly provide a pre-tightening force for the brush rollers 601 to press against the water hose body 1 through the turntable 6, so that the brush rollers 601 can make close contact with the water hose body 1, preparing for the subsequent washing work.

[0042] The water hose body 1 is guided into the water tank 2 by the first guide roller 7. Under the guidance of the first guide roller 7, the water hose body 1 can smoothly enter the water tank 2. Then, the water hose is guided to the second guide roller 8 and guided into the water tank 2 below the liquid level, ensuring that the water hose can be fully immersed in the cleaning solution poured into the water tank 2.

[0043] As the hose body 1 passes between the two brush rollers 601, the brush rollers 601 are positioned below the surface of the cleaning fluid and are pressed tightly against the hose body 1 by the pre-tension force generated by the spring force 5. With the conveyor belt 1, the brush rollers 601 brush the two sides of the hose body 1. Under the immersion of the cleaning fluid and the mechanical brushing action of the brush rollers 601, the stains and impurities on the surface of the hose are removed.

[0044] The stops 602 provided at the ends of the first guide roller 7, the second guide roller 8, and the brush roller 601 serve as limiting devices. When the water hose body 1 is conveyed in the equipment, the stops 602 limit the water hose body 1 on these rollers, preventing the water hose body 1 from shifting or slipping during conveyance and cleaning. This ensures that the water hose can pass through the water tank 2 along the predetermined path for cleaning, guaranteeing the stability and continuity of the entire cleaning process, thereby ensuring the cleaning effect and efficiency.
