Description

Technical Field

[0001] This invention relates to the field of fire hose testing technology, specifically a fire hose sealing testing device for fire testing. Background Technology

[0002] Fire hoses are the core equipment for transporting fire extinguishing media during fire rescue operations. Their sealing performance is a key indicator for ensuring the reliability of fire water supply operations and preventing safety accidents such as pipe bursts and leaks during firefighting. It is also a mandatory inspection item required by national standards. With the development of automated testing technology, some automated fire hose sealing testing devices have appeared on the market. These devices achieve automatic sealing and pressurization at both ends of the hose through mechanical structures, and automatically determine the sealing performance by combining pressure sensors and visual inspection systems, which improves the testing efficiency and accuracy to a certain extent.

[0003] However, in existing rotary fire hose sealing detection devices, the fire hose to be tested is placed on the rotary table in a circular manner and rotates synchronously with the circular rotary table below. The fire hose is a flexible pressure-bearing structure, and after inflation, it will expand radially and elongate axially. Without limiting constraints, the originally neatly coiled hose will squeeze, stack, cross, and twist due to expansion. Stacking and crossing will completely cover the leakage air bubbles, making it impossible to detect tiny leaks, resulting in missed detections and leaving fire safety hazards. At the same time, when the hose is placed on the rotary table in a flat winding manner, its bottom end is in direct contact with the rotary table surface, forming a detection blind spot that cannot be covered by the visual inspection system. Leaks within the blind spot cannot be identified, further increasing the risk of missed detections. It is impossible to achieve full-length, full-circumference detection of the hose without blind spots. Moreover, during use or storage, the surface of the fire hose is very easy to be covered by dust, mud, oil, and fibrous debris. The dirt on the surface of the hose will cover the leak, making it impossible for the visual inspection system to identify it.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing fire hose sealing testing devices. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a solution that differs significantly from existing technologies.

[0007] Preferably, the cleaning component includes a turntable disposed inside the main body, a fixed rod eccentrically fixed to one side of the turntable, a sliding frame slidably connected to the fixed rod, a fixed plate slidably connected to the sliding frame, a spring fixed to the top of the sliding frame, and the other end of the spring fixedly connected to a striking plate.

[0008] Preferably, the main body has a cavity that moves in conjunction with the turntable, the sliding frame, and the striking plate, and the fixing plate is fixedly connected to the inner wall of the cavity.

[0009] Preferably, the turntable is rotatably connected to the fixed plate, and the sliding frame has a cavity for cooperating with the fixed rod.

[0010] Preferably, the anti-deviation component includes a connecting seat disposed in the base, a fixing ring fixed on one side of the connecting seat, a movable component slidably connected inside the fixing ring, the movable component having a "Z" shaped cross section, fixing blocks slidably connected to both ends of the movable component, a movable column fixed to one end of the fixing block, a connecting component fixed to one side of the movable column, a lifting frame slidably connected to the connecting component, and the bottom end of the lifting frame being fixedly connected to the pressure plate.

[0011] Preferably, the abutment rod passes through the connecting seat and is slidably connected to the inner wall of the fixed ring. A spring is provided between the abutment rod and the moving column, and the connecting seat and the moving column are slidably connected.

[0012] Preferably, the fixed ring has a rectangular cavity with a cross-section that cooperates with the moving part, the moving part passes through the abutment rod, and the abutment rod has a parallelogram-shaped cavity with a cross-section that cooperates with the moving part.

[0013] Preferably, the base has a cavity for the movement of the connecting piece and the lifting frame, and the contact surfaces of the connecting piece and the lifting frame are both inclined surfaces.

[0014] Preferably, the limiting component includes a movable frame disposed at the bottom of the base, an electric telescopic rod fixed to one end of the movable frame, symmetrically distributed push plates fixed inside the movable frame, a connecting shaft fixed to one side of the push plate, the connecting shaft being rotatably connected to a guide plate, a fixed shaft being rotatably connected inside the guide plate, one end of the fixed shaft being fixedly connected to the base, a connecting frame fixed to the bottom end of the movable frame, a push rod slidably connected to one side of the connecting frame, a rotating column being rotatably connected to the outer wall of the push rod, and one end of the rotating column being fixedly connected to a turntable.

[0015] Preferably, the contact surface between the connecting frame and the push rod is an inclined surface, a protrusion is fixed on the outer wall of the push rod, and the rotating column is provided with a spiral groove that moves in conjunction with the protrusion on the outer wall of the push rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes the pressure of the contact rod during the water hose winding process. Through a linkage structure of parallelogram cavity and inclined surface, the pressure plate is driven to press down and limit the movement. After the water hose is inflated and expanded, the contact rod returns to its original position, and the pressure plate is raised and suspended. Automatic limiting is achieved by relying on the natural squeezing force of the water hose winding. The structure is simple, reliable, and energy-efficient. It can limit the water hose winding height and automatically rise when the water hose is inflated and expanded without affecting the normal expansion and deformation of the water hose. It balances the limiting effect with the compliance of the detection and avoids pressure detection distortion caused by improper limiting.

[0018] 2. This invention uses an electric telescopic rod to move the mobile frame and push plate, and drives the guide plate to rotate around the fixed axis via the connecting shaft. The guide plates on both sides of the hose are lifted outwards simultaneously, changing the support position of the hose, exposing the original contact blind area, and realizing blind area supplementary inspection. The synchronous rotation of the guide plates on both sides ensures that the hose is subjected to uniform force, avoids the hose from twisting or shifting during blind area supplementary inspection, ensures the stability of the detection posture during the supplementary inspection process, further improves the detection rate of micro-leakage points, eliminates the hidden danger of missed detection, ensures the authority of fire hose inspection, and prevents unqualified hoses from entering the use stage.

[0019] 3. This invention consists of two sets of symmetrical cleaning brushes, a movable seat, a fixed seat, and a return spring. It adopts an elastic clamping and follow-up rotation design. The cleaning brush is rotatably connected to the movable seat, and the movable seat is slidably engaged with the fixed seat. The spring provides continuous elastic pre-tension. The elastic clamping cleaning brush design can adapt to different diameter water hoses, ensuring that the cleaning brush is in close contact with the surface of the water hose. When the water hose moves, it drives the cleaning brush to rotate synchronously, which can thoroughly remove mud, dust, oil and other debris from the surface of the water hose, preventing dirt from blocking the leakage point. In addition, the cleaning brush can not only perform pre-treatment cleaning before inspection, but also squeeze the water hose to expel residual gas during winding, so that the water hose returns to a flat state, which is convenient for neat winding, reduces manual handling time, improves winding neatness and efficiency, and reduces labor intensity.

[0020] 4. This invention consists of a connecting frame, push rod, rotating column, turntable, fixed rod, sliding frame, and striking plate. It adopts a design of inclined plane linkage, spiral transmission and reciprocating striking, and reuses the power source of the blind spot elimination structure, which can make the cleaning brush generate high-frequency vibration, thoroughly shaking off the debris adhering to the inside of the bristles, thereby achieving cleaning by the cleaning brush. It solves the problems of easy dirt accumulation and reduced cleaning effect of existing cleaning brushes, and ensures stable cleaning ability of the cleaning brush for long-term use. The vibration cleaning design eliminates the need for manual disassembly and cleaning of the cleaning brush. Attached Figure Description

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] Please see Figures 1 to 14 This invention provides a technical solution: a fire hose sealing detection device for fire protection testing, comprising a main body 1, a placement tray 2 on one side of the main body 1, a rotating platform 3 rotatably connected to the top of the main body 1 via a drive motor, a fixed seat 4 at the top of the main body 1, a movable seat 6 slidably connected to the fixed seat 4 via a spring limit, a cleaning brush 7 rotatably connected to the movable seat 6, a cleaning component at the bottom of the fixed seat 4, a striking plate 9 fixed at one end of the cleaning component, and the cleaning component drives the striking plate 9 to clean the cleaning brush 7, multiple bases 5 at equal angles at the top of the rotating platform 3, a contact rod 10 slidably connected to one side of the base 5, an anti-deviation component inside the base 5, a pressure plate 12 fixed at one end of the anti-deviation component, and the contact rod 10 triggers the anti-deviation component to move the pressure plate 12 to prevent the hose from detaching from the limit when winding, and limit components on both sides of the base 5, a guide plate 14 rotatably connected to the limit components, and the limit components drive the hose to move at the top of the rotating platform 3.

[0038] In practice, the water hose to be tested is first placed in the placement tray 2 on one side of the main body 1, so that the water hose passes between the spring-limited movable seat 6 in the fixed seat 4 of the main body 1 and the rotatably connected cleaning brush 7. Then, one end of the water hose is connected to the air inlet tube in the rotating platform 3, which is rotatably connected to the drive motor at the top of the main body 1. The drive motor is started to rotate the rotating platform 3, and the water hose is gradually wound into the rotating platform 3. Multiple bases 5, which are set at equal angles at the top of the main body 1, are raised synchronously and gradually. The control system controls the inner base 5 to be raised first. The limiting components on both sides of the base 5 drive the rotatably connected guide plate 14 to constrain the water hose, so that the water hose is evenly wrapped around the outside of the base 5. During the wrapping process, the water hose squeezes the sliding contact rod 10 on one side of the base 5, triggering the anti-deviation component in the base 5 to move the pressure plate 12 to prevent the water hose from falling off the limit during wrapping. After the water hose is wrapped, the other end is sealed and air is added for testing. At the same time, the cleaning component can drive the tapping plate 9 at the bottom of the fixed seat 4 to vibrate and clean the cleaning brush 7, so as to achieve the vibration cleaning effect of the cleaning brush 7.

[0039] As a further embodiment of the present invention, the cleaning component includes a turntable 801 disposed inside the main body 1. A fixing rod 802 is eccentrically fixed on one side of the turntable 801. A sliding frame 803 is slidably connected to the fixing rod 802. A fixing plate 804 is slidably connected to the sliding frame 803. A spring is fixed at the top of the sliding frame 803. The other end of the spring is fixedly connected to the striking plate 9.

[0040] In practice, the turntable 801 inside the main body 1 rotates, which drives the fixed rod 802, which is eccentrically fixed on one side, to rotate. The fixed rod 802 slides in the sliding frame 803 and drives the sliding frame 803 to move back and forth along the fixed plate 804. The spring at the top of the sliding frame 803 then drives the striking plate 9 to move back and forth, thereby realizing the vibration self-cleaning of the cleaning brush 7.

[0041] As a further embodiment of the present invention, the main body 1 has a cavity that moves in conjunction with the turntable 801, the sliding frame 803, and the striking plate 9, and the fixing plate 804 is fixedly connected to the inner wall of the cavity.

[0042] In practice, the main body 1 provides space for the turntable 801, the sliding frame 803 and the tapping plate 9 through the cavity, and fixes the fixing plate 804 to the inner wall of the cavity to stabilize the sliding trajectory of the sliding frame 803 and provide an installation reference for the linkage action of the spring and the tapping plate 9, ensuring the smooth operation of the cleaning components.

[0043] As a further embodiment of the present invention, the turntable 801 is rotatably connected to the fixed plate 804, and the sliding frame 803 has an movable cavity that matches the fixed rod 802.

[0044] In practice, the turntable 801 and the fixed plate 804 maintain a limited rotational connection to ensure that the turntable 801 rotates stably and does not deviate. At the same time, the sliding frame 803 moves in conjunction with the fixed rod 802 through the cavity, so that the fixed rod 802, which is eccentrically fixed on one side of the turntable 801, can slide in the cavity, thereby driving the sliding frame 803 to move smoothly back and forth along the fixed plate 804, providing a stable transmission basis for the vibration cleaning action of the striking plate 9.

[0045] As a further embodiment of the present invention, the anti-deviation component includes a connecting seat 115 disposed in the base 5. A fixing ring 111 is fixed on one side of the connecting seat 115. A movable member 112 is slidably connected inside the fixing ring 111. The movable member 112 has a "Z" shaped cross section. Fixing blocks 113 are slidably connected to both ends of the movable member 112. A movable column 114 is fixed to one end of the fixing block 113. A connecting member 116 is fixed to one side of the movable column 114. A lifting frame 117 is slidably connected to the connecting member 116. The bottom end of the lifting frame 117 is fixedly connected to the pressure plate 12.

[0046] In practice, the transmission is triggered by the water hose squeezing the contact rod 10, which causes the Z-shaped moving part 112 in the fixing ring 111 on one side of the connecting seat 115 inside the base 5 to slide. The two ends of the moving part 112 push the connected fixing block 113 and the moving column 114 to move. The moving column 114 then drives the connecting part 116 on one side to slide. The connecting part 116 then drives the lifting frame 117 to move up and down, and finally drives the pressure plate 12 fixed to the bottom of the lifting frame 117 to move, thereby achieving the limitation and anti-deviation of the water hose.

[0047] As a further embodiment of the present invention, the abutment rod 10 passes through the connecting seat 115 and is slidably connected to the inner wall of the fixing ring 111. A spring is provided between the abutment rod 10 and the moving column 114, and the connecting seat 115 and the moving column 114 are slidably connected.

[0048] In practice, the abutment rod 10 passes through the connecting seat 115 and slides with the inner wall of the fixing ring 111. The spring between the abutment rod 10 and the moving column 114 provides a reset force. At the same time, the connecting seat 115 and the moving column 114 are slidably connected, so that when the abutment rod 10 is pressed and moved, it can drive the moving column 114 to slide smoothly. After the pressure is released, the whole is reset under the action of the spring, providing stable transmission and reset support for the anti-deviation assembly.

[0049] As a further embodiment of the present invention, the fixed ring 111 has a rectangular cavity with a cross section that cooperates with the movable member 112 to move. The movable member 112 passes through the abutment rod 10, and the abutment rod 10 has a parallelogram-shaped cavity with a cross section that cooperates with the movable member 112 to move.

[0050] In specific implementation, the rectangular cavity of the fixed ring 111 provides a guide for the movement of the moving part 112. The moving part 112 passes through the abutment rod 10 and cooperates with the cavity of the abutment rod 10 with a parallelogram cross section. When the abutment rod 10 slides horizontally, it can drive the moving part 112 to move vertically along the rectangular cavity of the fixed ring 111, realize the change of movement direction, and provide a transmission basis for the subsequent lifting and lowering of the pressure plate 12.

[0051] As a further embodiment of the present invention, the base 5 has a cavity that accommodates the connecting member 116 and the lifting frame 117. The contact surfaces of the connecting member 116 and the lifting frame 117 are both inclined surfaces.

[0052] In specific implementation, the cavity opened in the base 5 provides a space for the connecting piece 116 and the lifting frame 117 to move. The connecting piece 116 and the lifting frame 117 cooperate with each other through inclined surfaces, so that the horizontal movement of the connecting piece 116 can be converted into the vertical lifting movement of the lifting frame 117, thereby driving the pressure plate 12 to achieve the limiting and resetting action of the water hose.

[0053] As a further embodiment of the present invention, the limiting component includes a movable frame 131 disposed at the bottom of the base 5. One end of the movable frame 131 is fixed with an electric telescopic rod. Symmetrically distributed push plates 132 are fixed inside the movable frame 131. A connecting shaft 133 is fixed to one side of the push plate 132. The connecting shaft 133 is rotatably connected to the guide plate 14. A fixed shaft 134 is rotatably connected inside the guide plate 14. One end of the fixed shaft 134 is fixedly connected to the base 5. A connecting frame 135 is fixed to the bottom of the movable frame 131. A push rod 136 is slidably connected to one side of the connecting frame 135. A rotating column 137 is rotatably connected to the outer wall of the push rod 136. One end of the rotating column 137 is fixedly connected to the turntable 801.

[0054] In practice, the electric telescopic rod drives the movable frame 131 at the bottom of the base 5 to move, which in turn moves the symmetrical push plate 132 and connecting shaft 133 inside the movable frame 131. This causes the guide plate 14, which is rotatably connected to the connecting shaft 133, to rotate around the fixed shaft 134, thereby adjusting the position of the water hose support to eliminate blind spots in the detection. At the same time, the connecting frame 135 at the bottom of the movable frame 131 moves along with it, pushing the push rod 136, which is slidably connected to it, to move. The push rod 136 then drives the rotating column 137, which is fitted to the outer wall, to rotate, and finally drives the turntable 801, which is fixed to the rotating column 137, to rotate, providing power for the cleaning components.

[0055] As a further embodiment of the present invention, the contact surface between the connecting frame 135 and the push rod 136 is an inclined surface, a protrusion is fixed on the outer wall of the push rod 136, and a spiral groove is opened on the rotating column 137 to cooperate with the movement of the protrusion on the outer wall of the push rod 136.

[0056] In practice, the connecting frame 135 and the push rod 136 are engaged by inclined surfaces. When the connecting frame 135 moves, it can push the push rod 136 to move horizontally. The protrusion on the outer wall of the push rod 136 extends into the spiral groove of the rotating column 137 and moves along the groove, thereby converting the linear movement of the push rod 136 into the rotational movement of the rotating column 137, providing power for the operation of the subsequent cleaning components.

[0057] Working Principle: When using this fire hose sealing test device, the hose to be tested is placed in the placement tray 2 on one side of the main body 1. The hose is passed between the two cleaning brushes 7, and one end is connected to the air inlet pipe inside the rotating platform 3. The drive motor is started to drive the rotating platform 3 to rotate (a fixed seat 4 is set at the top of the main body 1, and the fixed seat 4 rotates synchronously with the rotating platform 3 when the rotating platform 3 rotates as a whole). Under the action of tension, the hose is gradually wound into the interior of the rotating platform 3, and the base 5 gradually rises. The control system controls the inner ring base 5 to rise first, so that the hose is evenly wrapped around the outside of the inner ring base 5 during the rotation. After the inner ring is finished, the outer ring base 5 rises in sequence, and the hose continues to be wound around the outside of the outer ring base 5 in an orderly manner. Finally, the hose is evenly arranged in multiple rings and tightly wrapped around the guide plate 14 on the outside of the base 5 (finally, multiple bases 5 are set at equal angles at the top of the rotating platform 3, with the rotation center of the rotating platform 3 as the only reference, and multiple bases 5 along the rotating platform 3). The hose is evenly distributed in the circumferential direction, and the central angles between adjacent bases 5 are equal. After the hose is wound, a sealing plug is installed at the other end. Compressed air with tracer smoke is injected into the hose through the air inflation device. The visual inspection system judges the sealing performance of the hose based on the smoke overflow. (The air inflation pipe inside the rotating table 3 adopts a conventional quick air inflation connector in the field of fire hose inspection. The end is equipped with a conical sealing plug and a clamp-type quick connector. The end of the hose is directly sleeved on the outside of the air inflation pipe. The airtight connection is achieved by the elastic clamping of the connector and the conical seal.)

[0058] During this process, when the water hose passes between the two cleaning brushes 7, the cleaning brushes 7 are squeezed by the water hose, which drives the movable seat 6 connected to it to retract into the fixed seat 4. The spring between the fixed seat 4 and the movable seat 6 is compressed, so that the cleaning brushes 7 always elastically press against the surface of the water hose. When the water hose continues to move, it drives the cleaning brushes 7 to rotate synchronously, effectively cleaning the mud, dust, oil and other debris attached to the outer wall of the water hose, avoiding dirt from blocking the leakage point and affecting the detection accuracy. At the same time, after the inflation test is completed, the placement tray 2 rotates in the opposite direction to wind up the tested water hose. At this time, the water hose passes between the cleaning brushes 7 again. Under the squeezing action of the cleaning brushes 7, the residual gas inside the water hose can be fully discharged, so that the water hose returns to a flat state, making it easier to wind up neatly and improving the winding regularity and efficiency.

[0059] Before the water hose is tightly attached to the guide plate 14, the pressure plate 12 is suspended and does not contact the top of the water hose. When the rotating table 3 drives the water hose to tightly wrap around the outside of the guide plate 14, the water hose squeezes the contact rod 10, causing the contact rod 10 to move into the base 5. When the contact rod 10 moves horizontally, it moves through the parallelogram-shaped cavity of the mating moving part 112 (the parallelogram-shaped cavity makes the contact surface between the contact rod 10 and the moving part 112 inclined), causing the moving part 112 to move vertically within the rectangular cavity of the mating moving part 112 in the fixing ring 111. Since the contact surface between the moving part 112 and the fixing block 113 is inclined, and the fixing block 113 is fixedly connected to the moving column 114, the vertical movement of the moving part 112 causes the moving column 114 to slide into the connecting seat 115 (the contact rod 10 only...). The moving column 114 needs to move horizontally inward, while the moving column 114 needs to move horizontally laterally. Since the two movements are perpendicular and cannot be directly transmitted, the moving part 112 is used to convert the horizontal, vertical and horizontal displacement. The moving part 112 smoothly transmits through the inclined surface, which can buffer the instantaneous squeezing force of the water hose on the contact rod 10 and avoid damage to the surface or structural components of the water hose from rigid transmission impact. This drives the connecting part 116, which is fixed to the moving column 114, to move synchronously. The contact surface between the connecting part 116 and the lifting frame 117 is an inclined surface. The horizontal movement of the connecting part 116 drives the lifting frame 117 to move vertically, and finally drives the pressure plate 12 to press down, which limits the height of the water hose wrapped around the outside of the base 5. This effectively limits the water hose winding height and prevents the water hose from shifting, stacking or crossing during the winding process, ensuring that the water hose is neatly arranged and providing a stable posture for subsequent expansion detection.

[0060] When the inflation device is activated, the flat water hose gradually expands and bulges under the action of air pressure. The squeezing effect of the water hose on the contact rod 10 disappears, and the contact rod 10 resets under the action of the internal elastic element. The pressure plate 12 is then raised and returns to the initial suspended position. At this time, the surface of the water hose is scanned in its entirety by the visual inspection system to determine whether there is any smoke overflow, thus achieving a preliminary test of the sealing performance. However, the contact position between the expanded water hose and the guide plate 14, as well as the contact position between the water hose and the top of the rotating table 3, will form local blind spots that cannot be directly observed.

[0061] To eliminate blind spots, the electric telescopic rod is activated, which drives the moving frame 131 to move. The movement of the moving frame 131 causes the fixed push plate 132 to move synchronously. This causes the guide plate 14 to rotate around the fixed shaft 134 (the guide plate 14 is rotatably connected to the base 5 through the fixed shaft 134) via the connecting shaft 133 that is rotatably connected to the push plate 132. The guide plates 14 on both sides of the hose are lifted outwards simultaneously, causing the hose to be partially lifted and the support position to change. The original contact blind spot is exposed within the visual inspection range, enabling supplementary inspection of the blind spot position. This achieves full-length and full-circumference inspection of the hose without blind spots, significantly improving the detection rate of minute leaks and avoiding missed detections.

[0062] When one of the movable frames 131 moves, it drives the connecting frame 135 fixed at its bottom to move synchronously. Since the contact surface between the connecting frame 135 and the push rod 136 is inclined, the vertical movement of the connecting frame 135 drives the push rod 136 to move horizontally. Furthermore, the rotating column 137 has a spiral groove that moves in conjunction with the protrusion on the outer wall of the push rod 136, allowing the rotating column 137 to rotate as the push rod 136 moves. This, in turn, drives the turntable 801 fixed to the rotating column 137 to rotate. The rotation of the rotating plate 801 drives the eccentrically positioned fixed rod 802 to rotate. When the fixed rod 802 rotates with the turntable 801, it slides back and forth in the cavity of the sliding frame 803, driving the sliding frame 803 to slide back and forth periodically along the fixed plate 804. The reciprocating sliding frame 803 drives the striking plate 9 through the spring, which continuously and evenly strikes and vibrates the bottom end of the fixed seat 4, causing the cleaning brush 7 to generate high-frequency vibration, shaking off the mud, sand and debris adhering to the inside of the bristles, thus achieving the cleaning effect of the cleaning brush 7.
