Description

Technical Field

[0001] This utility model relates to the field of fire pipeline leakage detection technology, specifically a high-efficiency detection device for fire pipelines. Background Technology

[0002] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials, and to transport fire extinguishing water, gas or other media. Due to long-term use, fire protection pipelines are prone to leakage and seepage at the joints, requiring the use of detection devices for inspection.

[0003] Utility model patent CN222704247U discloses a leak detection device for fire-fighting pipelines, including a clamp. The inner wall of the clamp has a water-guiding groove, and a leak hole is located at the center of the bottom of the clamp, connected to the water-guiding groove. A water-guiding pipe is welded below the bottom of the leak hole, and a movable pipe is welded to one end of the water-guiding pipe. A water-collecting platform is located inside the movable pipe. This leak detection device, by fixing the clamp to the joint of the fire-fighting pipeline, allows water to flow into the clamp when a leak occurs. Guided by the water-guiding groove, the water flows towards the leak hole and is discharged into the water-collecting platform through the water-guiding pipe. The weight of the water-collecting platform and the supporting force of the spring are at a horizontal level. As water continuously flows into the water-collecting platform, its weight increases, causing the spring to contract. As the water-collecting platform moves downward, a pressing column presses a push-button switch, activating the alarm.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: the device requires the screwing of multiple threaded rods during installation, resulting in low installation efficiency. At the same time, the device needs to accumulate water to increase its weight before it can trigger the switch, resulting in a delayed response. Therefore, it is necessary to propose a more convenient and timely efficient detection device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency testing device for fire protection pipelines to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency detection device for fire-fighting pipelines, including a lower arc-shaped clamp plate, an upper arc-shaped clamp plate hinged to one side of the top of the lower arc-shaped clamp plate, a locking mechanism installed on the surface of the lower arc-shaped clamp plate, an audible and visual alarm mechanism fixed on the surfaces of both the lower and upper arc-shaped clamp plates, multiple water-guiding grooves formed on the inner walls of both the lower and upper arc-shaped clamp plates, a humidity-sensitive resistor fixed at the converging end of each water-guiding groove, multiple first silicone sealing gaskets fixed on the inner walls of both the lower and upper arc-shaped clamp plates, avoiding the water-guiding grooves, and second silicone sealing gaskets fixed on both the front and rear sides of the inner walls of both the lower and upper arc-shaped clamp plates.

[0007] Preferably, the locking mechanism includes a mounting rod, and mounting grooves are provided on the surfaces of both the lower and upper arc-shaped clamping plates. The mounting rod is rotatably connected to the mounting groove surface of the lower arc-shaped clamping plate, and an extension rod is fixed to the surface of the mounting rod. A clamping block is slidably connected to the surface of the extension rod.

[0008] Preferably, a top block is fixed to one end of the extension rod, a compression spring is fixed to the surface of the top block, and one end of the compression spring is fixedly connected to the surface of the clamping block.

[0009] Preferably, the audible and visual alarm mechanism includes a protective shell, the surface of the protective shell located on the surface of the lower arc-shaped clamping plate is fixedly connected to the surface of the lower arc-shaped clamping plate, the surface of the protective shell located on the surface of the upper arc-shaped clamping plate is fixedly connected to the surface of the upper arc-shaped clamping plate, an MCU controller and a battery are fixedly fixed on the inner wall of the protective shell, a warning light and a buzzer are fixedly fixed on the top of the protective shell, and the MCU controller is electrically connected to a humidity-sensitive resistor through a waterproof connector.

[0010] Preferably, the MCU controller is set to activate the alarm after a three-second delay, and the protective shell surface is hinged with an inspection door.

[0011] Preferably, the cross-section of the water guiding channel is V-shaped, and the slope of the water guiding channel is 15 degrees.

[0012] Preferably, both the lower arc-shaped clamp and the upper arc-shaped clamp are made of stainless steel, and the protective shell is made of ABS+PC flame-retardant material.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] This invention achieves a one-time sealing by using a lower arc-shaped clamp, an upper arc-shaped clamp, and multiple sealing gaskets, eliminating the need for adjustment. The V-shaped slope water-guiding groove, combined with a humidity-sensitive resistor, allows for rapid detection of leaked liquid. The three-second delay confirmation logic significantly reduces false alarms for condensate. The quick-release locking mechanism utilizes the spring self-compensation principle to maintain a constant clamping force even when the pipeline vibrates or deforms due to temperature differences, eliminating the need for repeated tightening. The stainless steel clamp and flame-retardant protective shell provide dual protection against corrosion, high temperatures, and impact, extending the overall lifespan. Attached Figure Description

[0020] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0021] Please see Figure 1-4 A high-efficiency detection device for fire-fighting pipelines includes a lower arc-shaped clamp 1, an upper arc-shaped clamp 2 hinged to one side of the top of the lower arc-shaped clamp 1, a locking mechanism 3 installed on the surface of the lower arc-shaped clamp 1, an audible and visual alarm mechanism 4 fixed on the surfaces of both the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2, multiple water-guiding grooves 5 opened on the inner walls of both the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2, a humidity-sensitive resistor 6 fixed at the converging end of the water-guiding grooves 5, multiple first silicone sealing gaskets 7 fixed on the inner walls of both the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2, which are arranged to avoid the water-guiding grooves 5, and second silicone sealing gaskets 8 fixed on the front and rear sides of the inner walls of both the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2.

[0022] Through the above technical solution, the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2 are hinged to form an openable and closable annular space. During installation, the pipe is simply placed into the lower arc-shaped clamp 1 and then the upper arc-shaped clamp 2 is closed. After the locking mechanism 3 completes the quick locking, the audible and visual alarm mechanism 4 is in standby state. When leakage occurs on the outer wall of the fire pipeline, the liquid quickly gathers along the multiple water-guiding grooves 5 on the inner walls of the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2 to the humidity-sensitive resistor 6. The humidity-sensitive resistor 6 immediately senses and outputs a signal to the audible and visual alarm mechanism 4, realizing a second-level alarm. The first silicone sealing gasket 7 and the second silicone sealing gasket 8 together form a multi-layer seal to prevent liquid from leaking out from both ends and the middle gap of the clamp, ensuring detection accuracy and preventing corrosion of the clamp. The overall structure is compact, with few parts and easy disassembly and assembly, effectively reducing construction intensity and subsequent maintenance, and is suitable for online monitoring scenarios of fire pipelines with a known pipe diameter.

[0023] The locking mechanism 3 includes a mounting rod 301. The surfaces of the lower arc-shaped clamping plate 1 and the upper arc-shaped clamping plate 2 are both provided with mounting grooves. The mounting rod 301 is rotatably connected to the mounting groove surface of the lower arc-shaped clamping plate 1. An extension rod 302 is fixed to the surface of the mounting rod 301, and a clamping block 305 is slidably connected to the surface of the extension rod 302.

[0024] Through the above technical solution, the mounting rod 301 can rotate freely in the mounting groove of the lower arc-shaped clamping plate 1. When the extension rod 302 flips upward with the mounting rod 301 and approaches the upper arc-shaped clamping plate 2, the clamping block 305 slides down and presses against the outer surface of the upper arc-shaped clamping plate 2, forming a stable mechanical lock. When disassembly is required, the clamping block 305 can be released instantly by simply pushing it upward. The whole process does not require tools or screwing, which significantly shortens the on-site operation time. This locking mechanism 3 has a simple structure, reliable operation, and high durability, which can greatly reduce the frequency of maintenance and labor costs, and improve on-site safety and construction efficiency.

[0025] One end of the extension rod 302 is fixed with a top block 303, and a compression spring 304 is fixed on the surface of the top block 303. One end of the compression spring 304 is fixedly connected to the surface of the clamping block 305.

[0026] Through the above technical solution, when the clamping block 305 slides upward, the compression spring 304 is further compressed and stores elastic potential energy. When the clamping block 305 is manually released, the compression spring 304 provides a continuous and uniform downward clamping force to the clamping block 305. When unlocking is required, simply push the clamping block 305 upward, the compression spring 304 is compressed, and the clamping block 305 disengages from the upper arc-shaped clamping plate 2, achieving one-button release. The elastic compensation function of the compression spring 304 can automatically adjust the clamping force when the pipe vibration or temperature change causes slight changes in size, avoiding loosening or over-tightening. This structure eliminates vulnerable parts such as threads and pins, reduces failure points, and improves overall service life. At the same time, it is quick to operate, convenient to maintain, and significantly reduces on-site labor intensity.

[0027] The audible and visual alarm mechanism 4 includes a protective shell 401. The surface of the protective shell 401 located on the surface of the lower arc-shaped clamping plate 1 is fixedly connected to the surface of the lower arc-shaped clamping plate 1. The surface of the protective shell 401 located on the surface of the upper arc-shaped clamping plate 2 is fixedly connected to the surface of the upper arc-shaped clamping plate 2. An MCU controller 402 and a battery 403 are fixed on the inner wall of the protective shell 401. An alarm light 404 and a buzzer 405 are fixed on the top of the protective shell 401. The MCU controller 402 is electrically connected to the humidity-sensitive resistor 6 through a waterproof connector.

[0028] Through the above technical solution, the protective shell 401 is firmly installed on the outer surface of the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2, providing physical protection for the internal electronic components; the battery 403 continuously supplies power to the MCU controller 402, the warning light 404 and the buzzer 405. The MCU controller 402 receives the signal from the humidity-sensitive resistor 6 in real time. Once it is determined that there is continuous water leakage, it drives the warning light 404 to flash and the buzzer 405 to sound, forming a dual alarm of sound and light; the waterproof connector ensures that the electrical connection parts are not corroded by water vapor, avoiding false alarms and short circuits.

[0029] The MCU controller 402 is set to activate the alarm after a three-second delay. The protective housing 401 has an inspection door 406 hinged to its surface.

[0030] Through the above technical solution, after receiving the trigger signal from the humidity-sensitive resistor 6, the MCU controller 402 starts an internal delay program. Within the three-second delay, it continuously judges the validity of the signal. If the signal disappears, it is regarded as condensation or instantaneous splashing and no alarm is triggered. If the signal continues, the warning light 404 and the buzzer 405 are immediately driven to operate, which significantly reduces the false alarm rate. The maintenance door 406 is hinged to the protective shell 401 and can be opened quickly, which makes it convenient for on-site personnel to regularly check the working status of the MCU controller 402, replace the battery 403, or perform firmware upgrades. The combination of the delay logic and the openable maintenance door 406 not only improves the reliability of the alarm, but also reduces the difficulty of later operation and maintenance, and ensures long-term stable operation.

[0031] The cross-section of the water guide channel 5 is V-shaped, and the slope of the water guide channel 5 is 15 degrees.

[0032] Through the above technical solution, the cross-section of the water guiding channel 5 is V-shaped with a slope of 15 degrees. Gravity is used to quickly guide the leaked liquid to the humidity-sensitive resistor 6, avoiding the liquid from spreading and flowing on the inner wall of the clamp, which would cause detection delay. The V-shaped cross-section can provide a larger flow volume at the same width, while reducing liquid residue and preventing impurity accumulation. The slope design ensures the flow rate and avoids splashing caused by excessive steepness. This structure makes the detection response faster, the sensitivity higher, and reduces the frequency of channel cleaning, extending the maintenance-free cycle.

[0033] Both the lower arc-shaped clamp 1 and the upper arc-shaped clamp 2 are made of stainless steel, and the protective shell 401 is made of ABS+PC flame-retardant material.

[0034] Through the above technical solution, the lower arc-shaped clamping plate 1 and the upper arc-shaped clamping plate 2 are made of stainless steel, which has high strength, corrosion resistance and high temperature resistance, and can be exposed to humid, acid and alkali and ultraviolet environments for a long time without rusting; the protective shell 401 is made of ABS+PC flame-retardant material, which is both impact-resistant and flame-retardant, and can effectively prevent the spread of flames when a fire source is present on site, ensuring the safety of electronic components; the combination of the two materials makes the device complementary in terms of mechanical strength, environmental resistance and electrical safety, significantly extending the overall service life and making it suitable for various complex working conditions.

[0035] Working principle: The lower arc-shaped clamp 1 is placed below the fire pipe, and the upper arc-shaped clamp 2 is closed. The installation rod 301 in the locking mechanism 3 rotates, driving the extension rod 302 to make the clamp block 305 press the upper arc-shaped clamp 2 under the action of the compression spring 304, thus completing the rapid locking. At this time, the first silicone sealing gasket 7 and the second silicone sealing gasket 8 simultaneously adhere to the outer wall of the pipe to form a multiple seal. When leakage occurs on the outer wall of the pipe, the liquid is quickly collected by the V-shaped slope water guide groove 5 to the humidity sensor 6. The resistance change signal of the humidity sensor 6 is transmitted to the MCU controller 402 located in the protective shell 401 through the waterproof connector. After a three-second delay, the MCU controller 402 drives the warning light 404 to flash and the buzzer 405 to sound, realizing an audible and visual alarm. When the staff inspects, they can quickly check or replace the battery 403 through the hinged maintenance door 406. The whole process can be completed without tools. The overall structure is compact, quick to install, and timely in response, effectively solving the problems of slow installation and delayed response of traditional detection devices.
