Description

Technical Field

[0001] The utility model belongs to the technical field of water supply pipeline monitoring, and particularly relates to a leakage detection device for the butt joint of a water supply pipeline. Background Technique

[0002] Pipeline leakage detection is an important part of the pipeline system. Detecting the leakage problem at the water pipe butt joint can effectively prevent a large amount of water from being wasted in vain. In some water supply systems, in order to ensure stable water pressure, energy is required to drive equipment such as water pumps. If there is a leak, the system will require more energy to maintain the normal water supply pressure. Detecting and repairing the leak can reduce energy consumption.

[0003] In the existing monitoring methods for the butt joint position of water supply pipelines, generally, the internal pressure change of the pipeline is judged through a pipeline pressure gauge, or the water flow is monitored by the flow monitoring method. However, the pressure gauge in the pipeline is generally distributed at a relatively long distance from the pipeline butt joint position, and the water flow flows in the pipeline and is easily consumed by the pipeline temperature. Therefore, whether the pipeline leaks cannot be accurately and timely detected through the pressure gauge and flow monitoring, which is likely to affect the normal transportation of the water flow in the pipeline.

[0004] Therefore, a leakage detection device for the butt joint of a water supply pipeline is designed to change the above technical defects. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a leakage detection device for the butt joint of a water supply pipeline, which aims to solve the technical problem of not being convenient to accurately and quickly detect pipeline leakage under the existing technology.

[0007] (2) Technical Solutions

[0008] To solve the above technical problems, the utility model provides such a leakage detection device for the butt joint of a water supply pipeline, including a pipeline and a protective box. A flange is fixedly connected to the end face of the pipeline. A through groove is opened on the side wall of the protective box, and the pipeline penetrates through the through groove. The flange is located inside the protective box. A cover plate is assembled on the top surface of the protective box. The bottom of the cover plate is a convex structure, and the convex part of the cover plate abuts against the side wall of the pipeline. Bolts are movably connected to the corners of the top surface of the cover plate, and the bolts are all threadedly connected to the protective box. Two arc-shaped shells are assembled on the front and rear sides of the flange, and a plurality of humidity sensors are installed on the side walls of the arc-shaped shells. Brackets are fixedly connected to the bottom corners of the protective box.

[0009] Furthermore, a battery pack is arranged on the bottom surface of the inner cavity of the protective box. A photovoltaic panel is assembled on the top surface of the cover plate.

Detailed implementation manners

[0023] This detailed implementation manner is a leakage detection device for the docking position of a water supply pipeline, and its structural schematic diagram is asFigures 1 - 5 As shown in the figure, it includes a pipeline 1 and a protective box 3. A flange 2 is fixedly connected to the end face of the pipeline 1. A through groove 4 is opened on the side wall of the protective box 3. The pipeline 1 penetrates through the through groove 4. The flange 2 is located inside the protective box 3. A cover plate 5 is assembled on the top surface of the protective box 3. The bottom of the cover plate 5 is a convex structure. The convex part of the cover plate 5 abuts against the side wall of the pipeline 1, so as to form a sealed space inside the protective box 3, which can protect the docking position of the pipeline 1 during daily use. Bolts 13 are movably connected to the corners of the top surface of the cover plate 5, and the bolts 13 are all threadedly connected to the protective box 3. Two arc-shaped shells 6 are assembled on the front and rear sides of the flange 2. A plurality of humidity sensors 7 are installed on the side walls of the arc-shaped shells 6. Brackets 12 are fixedly connected to the bottom surface of the protective box 3 near the corners.

[0024] Among them, the bracket 12 can adopt an adjustable support structure to adjust its height according to the height of the protective box 3 from the ground to achieve the purpose of support.

[0025] As Figure 2 shown in the figure, a battery pack 10 is arranged on the bottom surface of the inner cavity of the protective box 3. A photovoltaic panel 11 is assembled on the top surface of the cover plate 5. The photovoltaic panel 11 is electrically connected to the battery pack 10. The humidity sensor 7 is electrically connected to the battery pack 10.

[0026] Specifically, an inverter can be used to connect the photovoltaic panel 11 and the battery pack 10 for current conversion. When the battery pack 10 supplies power to the humidity sensor 7, a control module also needs to be connected so that the humidity sensor 7 can send out detection signals. This is a mature existing technology and will not be elaborated in this solution.

[0027] As Figure 5 shown in the figure, convex blocks 8 are fixedly connected between the humidity sensors 7 on the inner wall of the arc-shaped shell 6. The convex blocks 8 are triangular structures. By setting the convex blocks 8, on the one hand, it can play a guiding role in the leaked water flow to reduce the water flow impact, and on the other hand, it can increase the strength of the arc-shaped shell 6.

[0028] As Figure 5 shown in the figure, two sealing strips 9 are fixedly connected to the inner side walls of the arc-shaped shells 6 respectively. The sealing strips 9 all abut against the side wall of the flange 2. By setting the sealing strips 9, the sealing performance between the arc-shaped shell 6 and the flange 2 can be increased, and the accuracy of leakage detection can be improved.

[0029] As Figure 2 shown in the figure, mounting holes are respectively opened on the opposite side walls of the two arc-shaped shells 6. Screws 14 are assembled in the two mounting holes on the same axis. The installation method using the screws 14 has the characteristics of simple structure, high installation stability and strong practicability.

[0030] As Figure 2 shown in the figure, the humidity sensors 7 are distributed in a circular array around the central axis of the pipeline 1.

[0031] Among them, the number of the humidity sensors 7 is not limited to this solution. The humidity sensors 7 can also be arranged at the position of the arc-shaped shell 6 close to the lower side, which is convenient for accurate monitoring when water flows down.

[0032] Working principle: When the pipeline 1 is docked, first place the protection box 3 at the docking position, then place the pipeline 1 and the flange 2 in the protection box 3 through the through slot 4, and fix them through the locking parts on the flange 2. Then, put the arc-shaped shell 6 on the flange 2 and fix the two arc-shaped shells 6 with screws 14. At the same time, the sealing strip 9 abuts against the flange 2, so that a closed environment is formed between the flange 2 and the arc-shaped shell 6. Then, connect the humidity sensor 7 and the photovoltaic panel 11 to the battery pack 10. The photovoltaic panel 11 is used for power generation, and the battery pack 10 is used to supply power to the humidity sensor 7 or other controllers. If leakage occurs at the docking position of the flange 2, the water flow can flow down along the arc-shaped shell 6 and contact the nearby humidity sensor 7. At this time, if the humidity is greater than the set threshold, the humidity sensor 7 emits an electrical signal to indicate that leakage has occurred in the pipeline 1 here, achieving the purpose of rapid detection.

[0033] All the technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
