Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for fire hose detection, and in particular to a leak detection device for fire hoses. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer of woven linen. Because fire pumps can provide high water pressure, fire hoses need to withstand extremely high water pressure during use to ensure that the water jet can be sprayed to the designated height. However, if there are problems such as side damage and leakage in the fire hose, the breach will expand rapidly under high pressure, posing unnecessary danger to firefighters.

[0003] Traditional testing methods typically involve two approaches: one is to place the fire hose in a water tank and observe the bubbles produced by injecting gas to determine if there is any air leakage; the other is to fill the fire hose with water and observe whether there are any water droplets dripping from its surface to determine its airtightness. Both of these methods are highly subjective and, although simple, have low accuracy, low efficiency, and are not suitable for rapid testing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a leak detection device for fire hoses.

[0005] The technical solution of this utility model is achieved through the following scheme: a leak detection device for fire hoses, including a support body, a first hose clamp, a second hose clamp, and a leak detection component. The support body is provided with a water-permeable frame, and a buffer groove is opened on the water-permeable frame. The first hose clamp and the second hose clamp are respectively installed at both ends of the support body and are arranged opposite to each other. The leak detection component is respectively installed on both sides of the support body and is located between the first hose clamp and the second hose clamp.

[0006] Through the above technical solutions, the first and second hose clamps can seal and release both ends of the fire hose, and the leak detection component can capture the leak signal, reducing workload and greatly improving detection efficiency. The buffer tank reduces the high-pressure impact on the first hose clamp and the fire hose body when water is injected into the fire hose, avoiding the impact from expanding the leak point of the fire hose and causing water splashing. The permeable frame drains the leaked water to prevent accumulation.

[0007] Preferably, the leakage detection component includes a telescopic cylinder, an arc-shaped mounting shell, a leakage sensing rope, and a positioning leakage detector. The telescopic cylinders are symmetrically installed on the side of the support body. The telescopic ends of the two telescopic cylinders are fixedly connected to the protruding side of the arc-shaped mounting shell. The leakage sensing rope is arranged on the concave side of the arc-shaped mounting shell, and the leakage sensing rope is externally connected to the positioning leakage detector.

[0008] Through the above technical solutions, the telescopic cylinder enables the arc-shaped mounting shell to be extended and adjusted, ensuring that the leak detection rope can cover the fire hose and capture the leak signal. Combined with the leak detection instrument, the location of the leak point can be accurately determined, providing accurate guidance for subsequent maintenance work. The arc-shaped mounting shell design makes the leak detection rope easy to disassemble and clean, reducing maintenance costs.

[0009] Preferably, the first hose clamping component includes a clamping device, a bearing ring, and a drive motor. The bearing ring is movably mounted on the outer surface of the clamping device, and the drive motor is connected to the clamping device through the bearing ring.

[0010] Preferably, the outer surface of the bearing ring is provided with an arc-shaped rack, the drive end of the drive motor is equipped with a drive gear, the drive gear meshes with the arc-shaped rack, and the clamping device adjustment handle is detachably mounted on the bearing ring by bolts.

[0011] Through the above technical solutions, the drive motor is connected to the clamping device through the bearing ring, which realizes the smooth transmission of power, making the clamping action faster and more accurate, enhancing the stability and durability of the clamping parts, and ensuring that the clamping device is in a locked state by the meshing and locking of the arc-shaped rack of the bearing ring and the gear at the drive end of the drive motor, thus preventing the locking from being released due to impact or vibration.

[0012] Preferably, the second hose clamp includes an upper clamping device and a lower clamping device, which are arranged opposite to each other and have the same structure.

[0013] Preferably, the upper clamping device includes a first electric hydraulic cylinder, a second electric hydraulic cylinder, a mounting frame, and a support plate. The mounting frame is installed on the side of the support body away from the first hose clamping member. The mounting frame is detachably mounted with symmetrically arranged first electric hydraulic cylinders. The telescopic ends of the two first electric hydraulic cylinders pass through the support body and are fixedly connected to the surface of the support plate. The support plate is equipped with a second electric hydraulic cylinder. The first and second electric hydraulic cylinders are arranged in an "L" shape.

[0014] Preferably, a water storage tank is provided on the support body below the permeable frame, and a drain pipe is connected to the outside of the water storage tank.

[0015] Through the above technical solutions, the upper and lower clamping devices are arranged opposite each other and have the same structure, ensuring that the fire hose is subjected to uniform force during clamping, reducing the risk of damage or leakage caused by improper clamping. By using the first and second electric hydraulic cylinders in conjunction, precise adjustment of the fire hose clamping can be achieved, allowing the fire hose to enter the taut state from the released state, which facilitates the installation and detection of the leakage detection component. The water storage tank and external drainage pipe effectively solve the problem of water accumulation caused by leakage or cleaning, and avoid water corrosion and damage to the equipment.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model can seal and release both ends of the fire hose through the first hose clamp and the second hose clamp, and capture the leakage signal with the water leakage detection component, reducing the workload and greatly improving the detection efficiency. The buffer groove reduces the high pressure impact on the first hose clamp and the fire hose body when water is injected into the fire hose, avoiding the impact from expanding the leakage point of the fire hose and causing water splashing. The water permeable frame drains the leaked water to avoid accumulation.

[0018] 2. The telescopic cylinder allows the arc-shaped mounting shell to be extended and adjusted, ensuring that the leak detection rope can cover the fire hose and capture the leak signal. Combined with the leak detection instrument, the location of the leak point can be accurately determined, providing accurate guidance for subsequent maintenance work. The arc-shaped mounting shell design makes the leak detection rope easy to disassemble and clean, reducing maintenance costs.

[0019] 3. The drive motor is connected to the clamping device through the bearing ring, which realizes the smooth transmission of power, making the clamping action faster and more accurate, enhancing the stability and durability of the clamping parts. Furthermore, the clamping device is kept in a locked state by the meshing and locking of the arc-shaped rack of the bearing ring and the gear at the drive end of the drive motor, preventing the clamping device from being released due to impact or vibration.

[0020] 4. The upper and lower clamping devices are arranged opposite each other and have the same structure, ensuring that the fire hose is subjected to uniform force during clamping, reducing the risk of damage or leakage caused by improper clamping. Through the coordinated use of the first and second electric hydraulic cylinders, precise adjustment of the fire hose clamping can be achieved, allowing the fire hose to enter the taut state from the released state, facilitating the installation and detection of the leakage detection component; the water storage tank and external drainage pipe effectively solve the problem of water accumulation caused by leakage or cleaning, avoiding corrosion and damage to the equipment caused by water accumulation.

[0030] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] A leak detection device for fire hoses, such as Figures 1-8As shown, the system includes a support body 1, a first hose clamp 2, a second hose clamp 3, and a leakage detection component 4. The support body 1 has a permeable frame 5 with a buffer groove. The first hose clamp 2 and the second hose clamp 3 are respectively installed at opposite ends of the support body 1. The leakage detection component 4 is installed on both sides of the support body 1, positioned between the first hose clamp 2 and the second hose clamp 3. A water storage tank 7 is located on the support body 1 below the permeable frame 5, connected to a drain pipe 8. The support body 1 is a cuboid with a cavity on its top surface, separated by the permeable frame 5 into two layers: one for detecting the fire hose 6, and the other for collecting water in the water storage tank 7. An electric valve is installed on the drain pipe 8 for easy drainage control. The fire hose 6 has some slack when passing through the two clamps and is not taut. Figure 2 , Figure 3 and Figure 5 As shown, the remaining portion naturally hangs into the buffer groove in the middle of the permeable frame 5, forming a concave shape. This effectively prevents the damage from expanding due to water injection and pressurization, thus avoiding liquid spraying. The buffer groove has chamfers on both sides for a natural transition. The support body 1 and the permeable frame 5 are made of high-strength, corrosion-resistant materials to ensure good working condition and testing performance during long-term use. The first hose clamp 2 is clamped and locked first, and then water is injected into the fire hose 6. The buffer groove effectively disperses and buffers the impact generated by high-pressure water injection, reducing the impact on the first hose clamp 2 and improving its service life.

[0033] Leakage detection assembly 4 includes telescopic cylinders 41, arc-shaped mounting shells 42, leakage sensing ropes 43, and a positioning leakage detector 44. Telescopic cylinders 41 are symmetrically mounted on the sides of the support body 1. The telescopic ends of the two cylinders 41 are fixedly connected to the protruding sides of the arc-shaped mounting shells 42. Leakage sensing ropes 43 are arranged on the concave sides of the arc-shaped mounting shells 42. The leakage sensing ropes 43 are externally connected to the positioning leakage detector 44. The arc-shaped mounting shells 42 on the two opposing leakage detection assemblies 4 extend from the telescopic rods and can form a cylindrical shape in the middle to cover the taut fire hose 6. The recessed side of the housing 42, which covers the fire hose 6, is equipped with an "S"-shaped leakage sensing rope 43. In conjunction with the positioning leakage detector 44, it can detect whether the fire hose 6 is leaking. When the fire hose 6 is close to the arc-shaped housing 42, the leakage point can be easily detected and located. Even if the diameter of the fire hose 6 is small and it is not tightly close to the arc-shaped housing 42, the leaking water droplets will slide down from the bottom and be sensed by the leakage sensing rope 43 in the lower half, so that the leakage range can be easily determined. The two ends of the protruding side of the arc-shaped housing 42 are fixed to the telescopic ends of the two telescopic cylinders 41, which effectively improves the stability of telescopic movement.

[0034] like Figure 7 and Figure 8As shown, the first hose clamp 2 includes a clamping device 21, a bearing ring 22, and a drive motor 23. The bearing ring 22 is movably mounted on the outer surface of the clamping device 21. The drive motor 23 is connected to the clamping device 21 through the bearing ring 22. An arc-shaped rack is provided on the outer surface of the bearing ring 22. A drive gear is mounted on the drive end of the drive motor 23, and the drive gear meshes with the arc-shaped rack. The adjusting handle of the clamping device 21 is detachably mounted on the bearing ring 22 by bolts. The clamping device 21 can be adjusted by turning the adjusting handle to change the opening size of the clamping opening in the middle, allowing the fire hose 6 to pass through the clamping device 21. One end is locked in place, and a buffer ring is installed in the middle. The buffer ring is made of a material with appropriate tension that can be tightened or loosened to prevent the tightening end from damaging the fire hose 6. The bearing ring 22 has a rack that matches the length of the adjustment range of the tightening device 21. It is driven by the drive motor 23 through meshing. The bearing ring 22 drives the adjustment handle to rotate, thereby adjusting the tightening degree of the tightening device 21. This saves time and effort. Furthermore, the engagement and locking of the arc-shaped rack of the bearing ring 22 and the gear at the drive end of the drive motor 23 ensures that the tightening device 21 is locked in place, preventing the lock from being released due to impact or vibration.

[0035] The second hose clamp 3 includes an upper clamping device and a lower clamping device. The upper clamping device and the lower clamping device are arranged opposite to each other and have the same structure. The upper clamping device and the lower clamping device clamp and lock the other end of the fire hose 6, so that the fire hose 6 is in a sealed state after being filled with water, which makes it easy to detect leaks. The upper clamping device and the lower clamping device are mirror images of each other. Due to the position of the lower clamping device, a matching receiving groove is opened on its permeable frame 5.

[0036] The upper clamping device includes a first electric hydraulic cylinder 31, a second electric hydraulic cylinder 32, a mounting frame 33, and a support plate. The mounting frame 33 is installed on the side of the support body 1 away from the first water hose clamp 2. The first electric hydraulic cylinders 31 are detachably mounted on the mounting frame 33 and are symmetrically arranged. The telescopic ends of the two first electric hydraulic cylinders 31 pass through the support body 1 and are fixedly connected to the surface of the support plate. The second electric hydraulic cylinder 32 is mounted on the support plate. The first electric hydraulic cylinders 31 and the second electric hydraulic cylinder 32 are arranged in an "L" shape. The second electric hydraulic cylinder 32 is covered with a protective shell 34 to prevent water corrosion. Preferably, there are four first electric hydraulic cylinders 31, two on the top and two on the bottom. Two mounting brackets are installed on the mounting frame 33, both facing the side opening of the support body 1, to provide stable control for the extension and retraction of the support plate. The second electric hydraulic cylinder 32 of the upper clamping device is vertically installed on the top surface of the support plate, and the second electric hydraulic cylinder 32 of the lower clamping device is installed on the bottom surface of the support plate. The two telescopic ends penetrate the support plate and are opposite each other. In the non-working state, they are stored inside the support plate. When working, the two telescopic ends extend to clamp and lock the fire hose 6, and are pulled by the first electric hydraulic cylinder 31 to straighten the fire hose 6. The position of the fire hose 6 after straightening and pulling up is at the same horizontal line as the leakage detection component 4, which can be easily covered for detection.

[0037] Working principle: The drive motor 23 is started to adjust the clamping opening of the clamping device 21 to the maximum range. The fire hose 6 is then passed through the first hose clamp 2 and the other end through the second hose clamp 3. At this time, the fire hose 6 located inside the support body 1 naturally hangs down into the buffer groove. The drive motor 23 is then started to clamp the fire hose 6 through the clamping device 21, thus sealing one end of the fire hose 6 and filling it with water. At this time, the second electric hydraulic cylinder 32 of the second hose clamp 3 is started to clamp the fire hose 6, locking both ends of the fire hose 6. The extension end of the first electric hydraulic cylinder 31 is then contracted, driving the second electric hydraulic cylinder 32 to contract. At this time, the second electric hydraulic cylinder 32 pulls the fire hose 6, making the fire hose 6 taut. The extension cylinder 41 is started to extend the arc-shaped mounting shell 42 inward, covering the fire hose 6. The leakage sensing rope 43 inside the shell is used to detect leakage, and the leakage range is determined in conjunction with the positioning leakage detector 44.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
