Description

Technical Field

[0001] This utility model belongs to the field of heating pipeline maintenance technology, specifically relating to a heating pipeline leakage detection and location device. Background Technology

[0002] As a key component of urban infrastructure, heating pipe networks bear the important task of providing heating in winter, and their operational status directly affects residents' quality of life and the city's energy efficiency. With the acceleration of urbanization and the increasing age of the pipe network, heating pipe networks face increasingly serious aging problems. Coupled with the influence of various factors such as changes in geological conditions, construction defects, and pipe materials, leaks in the network occur frequently. Leaks not only lead to a significant waste of water resources but also affect the normal operation of the entire heating system.

[0003] However, traditional methods for detecting leaks in heating pipe networks typically involve installing the detection equipment on the pipes and moving it around for inspection. But due to the varying diameters of heating pipe networks, the detection equipment may be unable to be installed, reducing its applicability and causing considerable trouble in locating leaks in heating pipe networks. To address this issue, the applicant proposes a leak detection and location device for heating pipe networks. Utility Model Content

[0004] The purpose of this utility model is to provide a leak detection and location device for heating pipe networks, which can automatically adapt to different pipe sizes during installation without the need for manual adjustment, effectively improving the scope of application and bringing more convenience to leak detection and location in heating pipe networks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A leak detection and location device for heating pipe networks, comprising:

[0007] The testing mechanism and the traveling mechanism mounted on both sides of the testing mechanism;

[0008] The detection mechanism includes a detection box, the top of which has a collection slot, and a water droplet sensor is fixedly installed inside the collection slot;

[0009] The walking mechanism includes a support frame that is slidably mounted on both sides of the detection box. The inner wall of the support frame is hinged with movable arms, which are arranged symmetrically. The ends of the movable arms are fixedly mounted with shafts, and one side of the shafts is rotatably mounted with a moving wheel.

[0010] Preferably, the inner wall of the collection tank is provided with a drainage hole, and the front end of the detection box is fixedly equipped with an audible and visual alarm that is electrically connected to the water droplet sensor.

[0011] Preferably, the detection box has an internal cavity for housing a battery.

[0012] Preferably, the support frame and the detection box are slidably mounted together via a sliding frame, and the front end of the detection box has a sliding groove for the sliding frame to slide.

[0013] Preferably, a tension spring is fixedly installed between the support frame and the detection box, and a handle is fixedly installed on one side of the support frame.

[0014] Preferably, a thrust spring is fixedly installed between the movable arm and the support frame, and the movable arm and the support frame are hinged together by a hinge seat.

[0015] Preferably, a drive motor corresponding to the movable wheel is fixedly installed on the top of the shaft frame, and anti-slip strips are evenly distributed on the surface of the movable wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model is equipped with a walking mechanism, which can easily lock the moving wheels onto the pipes of the heating network by pulling the support frame to both sides. By loosening the support frame, the moving arm can be used to rotate to form an opening and closing action, so that the moving wheels can be locked onto pipes of different diameters for walking and detection operations. It can automatically adapt to different pipe sizes during installation without the need for manual adjustment, which effectively improves the scope of application and brings more convenience to the detection and positioning of leaks in the heating network.

[0018] (2) The present invention has a collection trough on the top of the detection box, which can be moved to the bottom of the heating pipe network. When the pipe leaks, the water droplets can fall into the collection trough for collection and can contact the water droplet sensor to trigger an alarm in time to locate the leak. This allows the staff to know the location of the leak in time and effectively improves the leak detection effect. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a leak detection and location device for heating pipe networks includes:

[0030] The testing mechanism 2 and the traveling mechanism 1 mounted on both sides of the testing mechanism 2;

[0031] The detection mechanism 2 includes a detection box 21, and a collection groove 24 is provided on the top of the detection box 21. A water droplet sensor 26 is fixedly installed inside the collection groove 24.

[0032] The walking mechanism 1 includes a support frame 11 that is slidably mounted on both sides of the detection box 21. The inner wall of the support frame 11 is hinged with a movable arm 16, which is symmetrically arranged. The end of the movable arm 16 is fixedly mounted with a shaft frame 18, and a movable wheel 110 is rotatably mounted on one side of the shaft frame 18.

[0033] As can be seen from the above, when using this device, by carrying it to the heating network and pulling the two support frames 11 to both sides, the distance between the two support frames 11 can be increased. The walking mechanism 1 can be sleeved onto the pipe of the heating network from bottom to top. By releasing the support frames 11, the two support frames 11 can be closed together, and the moving wheels 110 can be engaged with the pipe. The opening and closing action is formed by the rotation of the movable arm 16, which allows the moving wheels 110 to engage with pipes of different diameters for walking and detection operations. It can automatically adapt to different pipe sizes during installation without the need for manual adjustment, effectively improving the scope of application and bringing more convenience to the detection and location of leaks in the heating network.

[0034] The rotation of the moving wheel 110 drives the walking mechanism 1 to move along the pipeline, which in turn drives the detection box 21 to move synchronously. Since the detection box 21 is located at the bottom of the pipeline, the water leaking from the pipeline can drip down into the collection tank 24 by gravity. The collection tank 24 is funnel-shaped, which allows the collected water droplets to slide into the water drop sensor 26. The water drop sensor 26 can easily detect the location of the leak, trigger the moving wheel 110 to stop rotating in time, and trigger an alarm to locate the leak. This allows the staff to quickly find the location of the leak for observation, effectively improving the leak detection effect.

[0035] Depend on Figure 4 It is known that the inner wall of the collection tank 24 is provided with a drain hole 25, and the front end of the detection box 21 is fixedly installed with an audible and visual alarm 23 that is electrically connected to the water droplet sensor 26.

[0036] As can be seen from the above, when the water droplet sensor 26 detects a water droplet, it can transmit a signal to the audible and visual alarm 23, which can trigger the audible and visual alarm 23 to sound and flash the light, so that the staff can discover it in time. The water in the collection tank 24 can be drained through the drain hole 25 to avoid water droplets accumulating on the water droplet sensor 26, which facilitates the detection of water leaks in other parts of the pipeline.

[0037] For details, please refer to Figure 5 As shown, the inside of the detection box 21 is provided with a receiving cavity 27, and a storage battery 28 is placed inside the receiving cavity 27.

[0038] As can be seen from the above, the storage cavity 27 can conveniently accommodate the storage battery 28, which can power electrical components and also has a charging function. No external power cord is required, which effectively improves the flexibility of use.

[0039] For details, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the support frame 11 and the detection box 21 are slidably installed together by a sliding frame 13, and the front end of the detection box 21 is provided with a sliding groove 22 for the sliding frame 13 to slide.

[0040] As can be seen from the above, the sliding frame 13 can slide along the sliding groove 22, which allows the support frame 11 to move horizontally smoothly and prevents the support frame 11 from tilting.

[0041] Example 2:

[0042] refer to Figure 1 and Figure 2 As shown, a tension spring 14 is fixedly installed between the support frame 11 and the detection box 21, and a handle 12 is fixedly installed on one side of the support frame 11.

[0043] As can be seen from the above, by using the handle 12, the two support frames 11 can be easily pulled horizontally to both sides. When the handle 12 is released, the tension spring 14 can be used to apply a pulling force to the support frame 11, which can pull the two support frames 11 together, so that the moving wheel 110 can be attached to the pipe.

[0044] refer to Figure 3 As shown, a thrust spring 17 is fixedly installed between the movable arm 16 and the support frame 11, and the movable arm 16 and the support frame 11 are hinged together by a hinge seat 15.

[0045] As can be seen from the above, the hinge 15 enables the movable arm 16 to rotate, allowing the moving wheel 110 to fit onto pipes of different sizes. The thrust spring 17 applies a thrust to the movable arm 16, ensuring that the moving wheel 110 fits precisely onto the outer wall of the pipe, preventing loosening.

[0046] refer to Figure 3 As shown, a drive motor 19 corresponding to the movable wheel 110 is fixedly installed on the top of the axle frame 18, and anti-slip strips 111 are evenly distributed on the surface of the movable wheel 110.

[0047] As can be seen from the above, the drive motor 19 can provide power to the moving wheel 110, which can easily drive the moving wheel 110 to rotate and drive the walking mechanism 1 to move along the pipe. The anti-slip strip 111 can increase the friction between the moving wheel 110 and the pipe, so that the moving wheel 110 will not slip and can ensure the stability of movement.

[0048] 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.
