[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0029] like Figure 1 As shown, a fire water pipe cleaning device of this application includes a brushing device 1, a flexible connecting pipe 2, a push-pull rod 3, and a support ring 4. These components are combined together to achieve effective brushing and cleaning of the inside of fire water pipes of different diameters and shapes.

[0030] The scrubbing device 1 consists of multiple bundles 11 of elastic bristles with adjustable spacing, one end of which is fixed to a base 12. The base 12 is designed with a flexible material covering its surface, allowing it to closely conform to irregular inner walls and provide excellent cleaning results. The bristles are designed with appropriate installation angles to ensure efficient cleaning of the inside of fire-fighting water pipes under suitable pressure. Simultaneously, to adapt to changes in pipe diameter and maintain stable cleaning performance, the base 12 is connected to the main frame 14 via a hinge mechanism 13, allowing for flexible angle adjustment. The hinge mechanism 13 enables the entire system to adapt to deformation, maintaining good contact with the inner wall even when dealing with pipes of complex shapes.

[0031] The flexible connecting pipe 2 is a key component used to connect the scrubbing device 1 and the push-pull rod 3. The flexible connecting pipe 2 is designed to give the entire system greater flexibility and operability: when dealing with fire hoses with bends or special structures, it provides sufficient compensation and compensatory stress in terms of length and direction, ensuring that the scrubbing action is accurately and effectively transmitted to any position on the fire hose; furthermore, it can significantly reduce the negative impact of external obstacles on internal operations during advancement or retrieval. For example, the flexible connecting pipe 2 can be made of wear-resistant materials to ensure reliability and durability over long periods, while multi-strand twisting technology enhances torsional strength, thereby ensuring stable transmission performance.

[0032] The push-pull lever 3 is the direct drive component for the brushing action. Users can move it back and forth using manual power or external mechanical power, thus propelling the entire cleaning equipment forward and backward along the internal trajectory of the water pipe, ultimately completing a thorough cleaning. The push-pull lever 3 should be robust yet easy to operate, allowing users to easily and accurately control its movement rhythm. One specific implementation involves selecting a lightweight metal alloy as the lever's structural material, and then optimizing the overall human-machine interface performance by combining it with drive mechanisms such as handwheels and servo motors.

[0033] A support ring 4 surrounds the outer periphery of the scrubbing device 1, providing not only radial physical support but also enhancing stability during the scrubbing process. When the device enters the target pipe, the support ring 4 helps adjust the scrubbing area to the appropriate position and ensures full contact between the bristles and the inner wall, distributing pressure evenly. This structure can be adjusted in terms of hardness, thickness, and other properties to handle various complex situations; a practical example is the use of rubber or silicone with good deformation properties as the support material, ensuring it can deform over a wide range without losing toughness and quickly return to its original state to continue providing stable support.

[0034] In this application, the brushing device 1 is equipped with bristle bundles with variable spacing and angle, combined with a base 12 wrapped in flexible material and its unique hinge fixing method, which achieves a sensitive and smooth response to changes in size while maintaining constant effective pressure; in addition, the flexible connecting pipe allows bending deformation so that the tool can reach more angles; and the end support component plays a key auxiliary positioning function, making each brushing stroke more precise and accurate; finally, the convenient and powerful push-pull mechanism controls the running path and depth, thereby ensuring that the cleaning purpose can be achieved efficiently whether in narrow straight pipes or tortuous and variable pipe environments.

[0035] In one embodiment, further reference Figure 2 and Figure 3 The brushing device 1 of a fire hose cleaning equipment according to this application includes multiple elastic bristle bundles 11, which are detachably mounted on a base 12 and equipped with adjusting bolts 15, thereby allowing adjustment of the maximum length of the elastic bristle bundles 11 extending out of the base 12. This design allows the equipment to maintain optimal contact pressure with the inner wall of the pipe in different application scenarios. Specifically, the base 12 has a flexible material covering surface to accommodate the different diameters of the pipes.

[0036] The flexible bristle bundle 11 is detachably fixed to the base 12, allowing users to easily replace or maintain the bristle bundle according to actual needs. Fine-tuning of the length is achieved through adjusting bolt 15, ensuring the equipment is suitable for pipes of different sizes. The introduction of this bolt not only improves ease of use but also ensures the equipment can continuously and efficiently clean the inside of pipes.

[0037] For example, the adjusting bolt 15 is located on one side of the base 12 and is perpendicular to the base 12. The user can change the effective extension length of the elastic bristle bundle 11 by turning the adjusting bolt 15. When the bolt is tightened, it pushes the base 12 to compress the elastic bristle bundle 11, reducing its maximum extension distance; conversely, loosening the bolt increases the effective extension range of the bristle bundle. This allows for quick adjustment of the equipment's operating status according to the specific diameter and shape requirements of the fire hose, ensuring effective removal of pipe wall dirt with each cleaning operation.

[0038] In one embodiment, see specific reference. Figure 4 The hinge mechanism 13 of a fire hose cleaning device according to this application includes two connecting plates 16. One connecting plate 16 is fixedly connected to the base 12 at one end, and has a pin hole at the other end for movably connecting to the main frame 14 via a pin 17; the other connecting plate 16 has a similar structure, ensuring that the position of the base 12 can be flexibly adjusted according to the shape and angle of different pipes during use. This hinge design allows the brushing device 1 to adjust its posture according to specific working conditions, making the cleaning process more efficient and thorough.

[0039] In practical implementation, one end of the base 12 is first fixedly connected to two parallel connecting plates 16. Each of these connecting plates 16 has a pin hole at the end away from the base 12, which is used to cooperate with the pin 17 to form a hinge engagement point. Then, the pin 17 is inserted into the aforementioned pin hole and into the corresponding position on the main frame 14 to complete the assembly of the entire mechanism. In addition, to ensure that the hinge can move smoothly during the operation of the equipment, the pin 17 must be made of a material with sufficient strength and a certain degree of flexibility, and an appropriate gap must be maintained between the pin 17 and other components to reduce frictional resistance during movement. On this basis, the main frame 14, as the supporting structure of the entire system, provides sufficient rigidity support for the entire system and bears the joint action of other key components to complete the expected function. For example, in practical application scenarios, the operator only needs to control the external power source to push or pull the push-pull rod 3 to drive all relevant parts, including the hinge mechanism 13 and the brushing device 1, to slide relative to each other along the pipe wall, thereby cleaning the dirt inside the pipe while automatically adapting to the internal environment of the pipe with different degrees of curvature and varying diameters.

[0040] In one embodiment, return to reference Figure 2 and Figure 3 The flexible material covering surface of the fire water pipe cleaning equipment of this application uses a wear-resistant sponge layer 18 as the outer covering material. This design makes the base 12 highly durable when directly contacting and brushing the inner wall of the fire water pipe. To further enhance the tightness of the fit with the pipe wall and ensure that no water leakage occurs during the cleaning process, a sealing rubber ring 19 is added to the outside of the sponge layer. The sealing rubber ring 19 has a certain degree of micro-elasticity, which can fit tightly into the inside of pipe walls of different shapes and sizes without increasing excessive frictional resistance, thereby effectively improving the operation performance and stability of the equipment.

[0041] The choice of abrasion-resistant sponge aims to provide effective wear cushioning and reduce damage caused by direct collision between the brush bristles and the pipe wall. Meanwhile, the sealing rubber ring 19 compensates for any minute gaps between the base 12 and the pipe wall, with particularly noticeable effects when the inner wall of the pipe is irregular. Furthermore, the sealing rubber ring 19 is pre-compressed and fitted to the outer edge of the base 12. As the brushing device 1 moves forward or backward with the push-pull rod 3, the sealing rubber ring 19 continuously and adaptively adjusts its deformation according to the specific pipe diameter, always maintaining a good seal.

[0042] For example, the wear-resistant sponge layer 18 can be mechanically pressed or otherwise reliably bonded to the surface of the base 12 in the scrubbing device 1. Next, after completing this process, a sealing rubber ring 19 with a certain degree of elasticity is fitted around the periphery of the above-treated sponge covering layer, ensuring that the two fit tightly and leaving an appropriate elastic margin to ensure that a good sealing environment can be formed in pipes of various diameters after subsequent installation.

[0043] In one embodiment, a miniature spring assembly 110 is added inside the main frame 14 of the fire hose cleaning device of this application. The miniature spring assembly 110 is installed between the main frame 14 and the scrubbing device 1, in the space below the support ring 4. The miniature spring assembly 110 consists of a series of independent small springs arranged closely to form a matrix structure. The two ends of each spring are fixed to the inner surface of the main frame 14 and the flexible connection structure supporting the scrubbing device 1, respectively. This arrangement allows the miniature spring assembly 110 to absorb the instantaneous impact transmitted by the push-pull rod 3 and to evenly distribute the force.

[0044] The miniature spring assembly 110 effectively mitigates mechanical stress fluctuations caused by the push-pull operation, ensuring that the brushing device 1 maintains a constant pressure distribution throughout the entire push-pull process, regardless of complex pipe diameter changes such as straight or curved pipes. This pressure is sufficient to ensure that the elastic bristles make close contact with the pipe wall without causing excessive wear or damage to the pipe.

[0045] For example, in practical implementation, when the user applies external force to the push-pull rod 3 to drive the scrubbing device 1 along the pipe, the reaction force generated by each pushing action is partially absorbed and buffered by the micro-spring assembly 110. By adjusting the preload and material properties of the micro-springs, effective cleaning of pipes with different diameters can be achieved. Furthermore, this design also considers the usage requirements in different environments, such as the possibility of changes in pushing and pulling resistance due to foreign objects in the pipe. Therefore, selecting appropriate spring specifications ensures consistent cleaning results regardless of whether the flow is smooth or obstructed.

[0046] In one embodiment, an angle measuring sensor 111 is mounted on one side of the brushing device 1 of the fire-fighting water pipe cleaning equipment of this application. This sensor can sense and record the change data of the tilt angle of the brush head in real time. By installing this sensor on one side of the brushing device 1, regardless of the shape of the fire-fighting water pipe in which the brush head is located, the angle parameters of the brush head relative to the pipe wall can be dynamically captured during operation, which facilitates the equipment to accurately adapt to water pipes with complex bending characteristics.

[0047] For example, the specific implementation includes using an angle measuring sensor 111 composed of precision electronic components, which is securely mounted on the outer edge of the scrubbing device 1 near the support ring 4. Based on this, flexible connection technology ensures stable transmission of the sensing signal to the control system, guaranteeing accurate and reliable angle information measured under different cleaning conditions. Simultaneously, a robust connection to the main frame 14 of the scrubbing device 1 ensures the structural stability and operational accuracy of the angle measuring sensor 111 throughout the cleaning process. This mounting method combines mechanical fasteners and elastic buffer components to adapt to interference from factors such as vibration that may arise in the working environment. Therefore, even when facing waterways with various complex and winding paths, the precise trajectory of the relative posture change of the scrubbing tool can still be obtained, allowing for further analysis or adjustment of cleaning process parameters.

[0048] In one embodiment, a support ring 4 of a fire hose cleaning device of this application is installed on the outer circumferential surface of the scrubbing device 1. The support ring 4 is a segmented ring body composed of several independent rotatable segments. These segments achieve flexible rotation and extension / retraction among themselves through a carefully designed connection structure. The hydraulic component is one of the key components, responsible for controlling the radial extension and retraction of each segment, ensuring that the segments can automatically adjust according to changes in pipe specifications, and achieving good fit to the inner walls of different types of pipes and pipes with curved bends. This design concept gives the support ring 4 high adaptability and flexibility.

[0049] Specifically, each segment of the segmented ring is equipped with a built-in micro hydraulic cylinder or a corresponding hydraulic component for pushing and retracting the segment. The hydraulic system configuration ensures that each segment can be precisely adjusted relative to the central axis of the scrubbing device 1 as needed under different operating conditions, thereby providing stable radial support and assisting in the directional and force transmission during the scrubbing process. For example, when encountering sudden changes in pipe diameter or curved sections, by adjusting the state of each segment, the support ring 4 can smoothly adapt to changes in pipe wall curvature without sacrificing cleaning efficiency.

[0050] In one embodiment, the push-pull rod 3 of the fire hose cleaning device of this application is configured as a hollow structure and is connected to the flexible connecting pipe 2, with a built-in flexible water supply pipe 112. One end of the water supply pipe extends from the inside of the push-pull rod 3 to the position of the scrubbing device 1, ensuring that the high-pressure water flow or cleaning agent can directly reach the scrubbing work point to assist in deep stain removal. This design optimizes the traditional water cleaning mode, improving cleaning efficiency and effect by introducing a high-pressure water source or professional cleaning agent.

[0051] The internal cavity design of the aforementioned push-pull rod 3 provides crucial support for the overall functionality of the device. Specifically, the water delivery pipe within the push-pull rod 3 can be made of a flexible material to ensure it is not easily deformed or damaged during external pushing and pulling, and to maintain unobstructed flow even when bent. Simultaneously, the addition of the flexible connecting pipe 2 achieves a smooth transition between the two, maintaining good sealing performance and preventing leakage of water or other fluids. Therefore, stable liquid delivery performance is guaranteed even under significant bending. Furthermore, considering the changing needs of actual application scenarios, the specific path of the water delivery pipe can be carefully arranged and fixedly installed to maximize the advantages of the added functionality without affecting the operation of the original components.

[0052] For example, during manufacturing, high-pressure resistant materials can be used to create the water pipes, and special connectors can be used to precisely align the ends of the pipes with the push-pull rod 3 and the scrubbing device 1. For instance, a threaded tightening or nested locking mechanism can ensure a tight fit between all parts while also providing easy disassembly and replacement, thus meeting the requirements of on-site inspection and maintenance. Furthermore, the pressure wave oscillation problem that may be caused by the relative displacement generated during the push-pull operation can be solved by arranging vibration-absorbing elements around the cavity, ensuring the reliability of the entire system.

[0053] In one embodiment, the outer edge of the push-pull rod 3 of the fire hose cleaning device of this application is provided with a uniformly arranged human-machine interactive operation handle group 113, such as... Figure 1 As shown. This design allows the operator to adjust the propulsion force by manual rotation. The human-machine interface control handle assembly 113 is mounted on the outer circumference of the push-pull rod 3, ensuring flexible control of the equipment's operational intensity even in confined spaces, thus improving the equipment's applicability and portability. Specifically, the control handle assembly is fixedly connected to the push-pull rod 3, ensuring a tight and secure connection to maintain overall structural stability when force is applied and to transmit the required force.

[0054] Specifically, this installation method not only provides sufficient mechanical strength to support various force adjustment needs, but also simplifies the assembly process and maintenance procedures. The human-machine interface control handle assembly 113 consists of multiple independently adjustable handles, allowing users to adjust the appropriate hand position and force application method according to actual conditions, ensuring a good operating experience throughout the entire use process. For example, the handle surface can be equipped with anti-slip textures or covered with soft materials to increase grip comfort and prevent slippage.

[0055] Specifically, the secure connection between the operating handle and the push-pull rod 3 can be achieved through threaded tightening, embedded bayonet, or other similar physical connection methods. At the same time, the design must fully consider operational safety and convenience. These structural improvements ensure that the equipment can effectively cope with complex working environments and achieve better cleaning results in actual use.

[0056] In one embodiment, the flexible connecting pipe 2 of the fire hose cleaning equipment of this application is made of multi-layer reinforced woven composite corrugated rubber hose. This special material combination not only gives the flexible connecting pipe 2 excellent flexibility, enabling it to adapt to different bending and expansion requirements, but also has corrosion resistance and aging resistance, ensuring that it can maintain a good working condition for a long time under various complex environmental conditions. Specifically, the selected materials are specially treated to exhibit excellent protective properties when facing adverse factors such as chemical corrosion and ultraviolet radiation, ensuring the stability and reliability of the entire equipment after long-term use.

[0057] The flexible connecting pipe 2 connects the scrubbing device 1 and the push-pull rod 3 at both ends, forming a continuous transmission link. The scrubbing device 1, located at the front end, is responsible for physical contact scrubbing and cleaning the inner wall of the fire water pipe; the push-pull rod 3, fixed at the rear end, provides power to move the scrubbing device 1 along the inside of the pipe. The two are connected by the flexible connecting pipe 2, providing necessary adaptability in length and direction to ensure effective cleaning at different locations inside the pipe. A support ring 4 is installed on the outer circumference of the scrubbing device 1, providing radial support and also assisting in adjusting the fit between the scrubbing device 1 and the inner diameter of the fire water pipe. This structural arrangement allows for more precise and extensive internal cleaning.

[0058] For example, to ensure the technical realization of the functional characteristics of the flexible connecting pipe 2, one or more layers of high-strength synthetic fibers can be woven into a mesh structure inside the flexible connecting pipe 2, and then coated with a composite material coating with good corrosion resistance and ductility on the outside. Simultaneously, the proportion and arrangement of the multiple layers of materials can be adjusted according to the actual application requirements to achieve optimal mechanical property matching and ensure sufficient stability of the connection. Through precise design and rigorous material selection, this feature fully meets the harsh conditions that may be encountered in different operating environments.

[0059] In one embodiment, a support ring 4 of a fire hose cleaning device of this application is mounted on the outer peripheral surface of a scrubbing device 1. Multiple ball bearing units 114 are mounted on the support ring 4. Each ball bearing unit 114 specifically consists of an inner ring, an outer ring, and internally embedded balls. This structure ensures that the support ring 4 can roll smoothly relative to the wall of the fire hose during the scrubbing process, reducing frictional loss. Through the precise fit and mounting position of their inner and outer rings, these ball bearing units 114 maintain a stable radial support force in the inner diameter direction of the fire hose during the scrubbing action. Simultaneously, the rolling characteristics of the balls effectively reduce wear during system operation, contributing to the long-term reliable operation of the entire cleaning system.

[0060] For example, in one specific embodiment, each set of ball bearing units 114 is securely mounted on a predetermined position on the support ring 4 to ensure that each ball can evenly distribute the pressure during brushing and roll smoothly. This arrangement allows all ball bearing units 114 to function effectively when the push-pull rod 3 pushes the brushing device 1 to move axially along the fire water pipe, achieving a relatively smooth rolling effect along the pipe surface.

[0061] In one embodiment, a quick-plug waterproof socket interface 115 is provided between the electrical components of each component of the fire hose cleaning equipment of this application. This design ensures that wires and other electronic circuits are not damaged during subsequent inspection, maintenance, and replacement of worn parts. Specifically, the waterproof socket interface 115 is installed near the interconnection points of the main components to ensure the effectiveness and safety of the electrical circuits. With this design, the electrical connections of the equipment are no longer limited by traditional fixed wiring methods, and the separation or reconnection of components can be easily completed without damaging other components, thereby improving the ease of operation and the service life of the equipment.

[0062] To adapt to complex working environments, the quick-plug waterproof socket interface 115 combines high-quality sealing materials with a metal shell, providing both excellent waterproof performance and sufficient mechanical strength. For example, such interfaces are installed at the transition points between the flexible connecting tube 2 and the brushing device 1, and between the push-pull rod 3 and other components. These locations are typically key areas for field maintenance, where frequent movements can easily cause ordinary connectors to loosen or allow water ingress, while the waterproof socket interface 115 effectively prevents this. Furthermore, this interface design allows for direct disconnection of related circuits without affecting other components, facilitating the commissioning and troubleshooting of the electrical system.

[0063] For example, using spring-loaded contact terminals as a key component of the quick-release mechanism ensures connection stability while providing good conductivity. Specifically, one side of the electrical connector is designed with a recess to accommodate a protruding structure on the other side. The two interlock elastically to maintain a tight fit, forming a low-impedance path to guarantee normal power supply. When disassembly is required, only appropriate force is needed to overcome the spring force and separate the two ends. Different power polarities and signal types can be easily distinguished by color coding. This significantly improves assembly and maintenance efficiency while ensuring functionality.

[0064] In actual operation, when this device is in use, the push-pull rod 3 can be pushed or pulled manually or mechanically to make the scrubbing device 1 reciprocate along the inside of the fire water pipe. The flexible connecting pipe 2 plays a key role in this process, ensuring that the scrubbing action can be smoothly transmitted to all parts of the fire water pipe through its adaptability in length and direction. At the same time, the support ring 4 provides radial support, adjusts the degree of fit between the device and the inner wall of the pipe, and enhances the cleaning effect. The elastic bristle bundles 11 in the scrubbing device 1 can adjust the spacing according to the angle of the base 12 relative to the main frame 14, and with the flexible material on the surface of the base 12 and the flexible movement provided by the hinge mechanism 13, the elastic bristles can adapt to fire water pipes of different diameters and maintain appropriate contact pressure, ensuring an efficient and gentle cleaning process. The whole operation is simple and direct, and can be used for cleaning tasks inside fire water pipes of different specifications while ensuring cleaning quality.
