Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology, and in particular relates to a leak detection device for fire protection pipelines. Background Technology

[0002] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials and transport fire extinguishing water, gas or other media. Before installation and use, fire protection pipelines may rust due to long-term storage. In some cases, severe rust may even rust through the pipe wall, leading to leaks during installation and use. Therefore, leak detection is necessary before installation to prevent leaks.

[0003] Comparing this to Chinese patent CN222188699U, which discloses a fire-fighting pipeline leak detection device, the device includes a detection tank, a drive motor, and a support plate. Mounting side plates are fixedly installed on both sides of the detection tank, and two sets of fixing vertical plates are fixedly installed on the top of the mounting side plates. This allows for the simultaneous detection of one set of fire-fighting pipelines while another set is mounted on the support plate, enabling cyclical detection of the fire-fighting pipelines. This maximizes the time available for detecting the fire-fighting pipelines, shortens installation time, increases detection efficiency, and enhances the device's practicality. Furthermore, this detection method can detect fire-fighting pipelines of varying lengths, expanding the device's applicability and further improving its usability.

[0004] However, the aforementioned patent relies solely on central fixation combined with up-and-down flipping motion, which makes it difficult to guarantee the reliability of fire-fighting pipe fixation and reduces operational stability. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a fire pipeline leak detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire-fighting pipeline leak detection device includes a water tank for holding water for detection, and a drive device disposed in the middle of the water tank for alternately raising and lowering the fire-fighting pipeline for immersion in water on both sides. Air supply devices for separately inflating and detecting are disposed on both sides of the drive device. The drive device includes a drive shaft, with a servo motor disposed at one end of the drive shaft. Two drive gears are symmetrically mounted on the drive shaft, and each drive gear has a set of clamping components symmetrically meshed on both sides for fixing the alternately raising and lowering of the fire-fighting pipeline. The air supply device includes a three-way air inlet pipe, with two control air valves symmetrically mounted at both ends of the three-way air inlet pipe. Air supply hoses are mounted on the control air valves, and end cap assemblies for sealing both ends of the fire-fighting pipeline are mounted on the top of the air supply hoses.

[0008] Furthermore: the water tank device includes a water tank box, two support seats are symmetrically installed on the top of the water tank box, and two limiting components for guiding lifting and moving are symmetrically arranged inside the water tank box.

[0009] Furthermore: the limiting component includes a fixed frame, the top of the fixed frame is provided with a limiting slide, and the limiting slide is symmetrically provided with two limiting grooves at the front and rear.

[0010] Furthermore: the clamping assembly includes two symmetrically arranged lifting frames, with racks provided on the opposite faces of the two lifting frames, and fixing straps and buckles provided at the bottom of the lifting frames.

[0011] Furthermore: the lifting frame has an I-shaped cross-section, and the rack is embedded below the side surface of the lifting frame.

[0012] Furthermore, the end cap assembly includes a venting end cap communicating with the gas delivery hose and a sealing end cap for completely sealing the end of the fire-fighting pipeline.

[0013] Furthermore, the gas delivery hose is connected to the control valve and the vent cap clamp, respectively.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The system adopts a symmetrical gear and rack transmission with fixed ends (drive gear + lifting frame rack), and uses a single servo motor to drive the reverse synchronous movement of the pipes on both sides. The fire-fighting pipes on both sides are raised and lowered alternately to detect leaks, which increases the reliability of the fixation and improves the stability of operation.

[0016] 2. The design of the I-shaped lifting frame and the limiting slide groove reduces frictional resistance while ensuring load-bearing capacity; the quick clamping structure of fixing straps and locks can complete the fixing of pipes with a diameter of Φ100-300mm within 30 seconds.

[0017] 3. The three-way air intake pipe, combined with the independent intake control, ensures accurate air supply and convenient operation. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 A fire pipeline leak detection device includes a water tank for holding water for detection, and a drive device in the middle of the water tank for alternately raising and lowering the fire pipeline for immersion in water on both sides. Air supply devices for separately charging and detecting are provided on both sides of the drive device.

[0027] In this embodiment: the water tank device includes a water tank 101, with two support seats 102 symmetrically installed on the top of the water tank 101, and two limiting components for guiding the lifting and lowering movement symmetrically arranged inside the water tank 101; the limiting components include a fixed frame 103, with a limiting slide 104 provided on the top of the fixed frame 103, and two limiting grooves 105 symmetrically arranged at the front and rear of the limiting slide 104; the water tank 101 is filled with water to immerse the fire pipe for leak detection, and the fixed frame 103 supports the limiting slide 104 and limits the lifting frame 204 to move up and down through the limiting grooves 105;

[0028] In this embodiment: the driving device includes a drive shaft 201, with a servo motor 203 at one end of the drive shaft 201. Two drive gears 202 are symmetrically mounted on the drive shaft 201, and each drive gear 202 has a set of clamping components for fixing the alternating lifting and lowering of the fire-fighting pipe symmetrically meshed on both sides. The clamping components include two symmetrically arranged lifting frames 204, with racks 207 arranged on opposite sides of the two lifting frames 204. The bottom of the lifting frames 204 is provided with fixing straps 205 and a lock 206. The lifting frame 204 has an I-shaped cross-section, and the racks 207 are embedded below the side surface of the lifting frame 204. First, the fixing straps 205 are used to wrap around the fire-fighting pipe. The fire pipe is clamped and fixed between the bottom of the two lifting frames 204 on the same side near the end of the pipe. The servo motor 203 is started, and the servo motor 203 drives the two drive gears 202 to rotate through the transmission shaft 201. At the same time, the gears 207 on the front and rear lifting frames 204 are engaged, pushing one lifting frame 204 to descend along the limiting slide groove 105 under the support of the limiting slide 104, immersing the fire pipe into the water tank 101 for leak detection. The other lifting frame 204 rises along the limiting slide groove 105 under the support of the limiting slide 104, raising the bottom to facilitate clamping and fixing the second fire pipe.

[0029] In this embodiment: the air supply device includes a three-way air inlet pipe 305, with two control air valves 304 symmetrically installed at both ends of the three-way air inlet pipe 305. An air supply hose 303 is installed on the control air valve 304, and an end cap assembly for sealing both ends of the fire-fighting pipeline is installed at the top of the air supply hose 303. The end cap assembly includes a venting end cap 302 connected to the air supply hose 303 and a sealing end cap 301 for completely sealing the end of the fire-fighting pipeline. The air supply hose 303 is connected to the control air valve 304 and the venting end cap 302 by clamps. The sealing end cap 301 and the venting end cap 302 are installed at both ends of the fire-fighting pipeline. During testing, the control air valve 304 is controlled so that the compressed air connected to the three-way air inlet pipe 305 passes through the corresponding air supply hose 303 and the venting end cap 302 into the fire-fighting pipeline immersed in the water tank 101. If there is a leak, air bubbles will float out of the water.

[0030] Working principle: First, use cable ties 205 to wrap around the fire-fighting pipe near the end and insert locks 206 to secure it, clamping and fixing the fire-fighting pipe between the bottoms of two lifting frames 204 on the same side. Then, install the sealing end cap 301 and the venting end cap 302 at both ends of the fire-fighting pipe. Next, start the servo motor 203, which drives two drive gears 202 to rotate through the transmission shaft 201. At the same time, the servo motor 203 engages the racks 207 on the front and rear lifting frames 204, pushing one lifting frame 204 down along the limiting slide groove 105 under the support of the limiting slide 104, thus lowering the fire-fighting pipe. Leak detection is performed by immersing the pipe in the water tank 101. Another lifting frame 204 rises along the limiting slide 105 under the support of the limiting slide 104, raising the bottom to facilitate clamping and fixing the second fire pipe. During the test, the control valve 304 is used to allow compressed air connected by the three-way air inlet pipe 305 to pass through the corresponding air supply hose 303 and the vent end cover 302 into the fire pipe immersed in the water tank 101. If there is a leak, air bubbles will float to the surface of the water. After the test is completed, the above steps are reversed to perform leak detection on the second fire pipe. This process is repeated alternately.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
