Description

Technical Field

[0001] The utility model relates to the technical field of pipeline monitoring, in particular to a metering detection device for pipeline leakage detection. Background Art

[0002] Pipelines are responsible for the transmission of gases and liquids. They may form cracks due to loose connections, material aging, and external damage, which can lead to fluid leakage due to the internal and external pressure differences. To ensure safety, it is crucial to regularly inspect pipelines and assess whether their leakage meets established standards. If it exceeds the standards, replacement or repair measures must be taken. Currently, in the process of measuring leaked fluids, metering personnel need to personally collect the leaked fluid within a specific period of time, and then accurately weigh it to calculate the leakage flow rate during that period. However, this method faces the problem of low fluid handling efficiency after the measurement is completed, and metering personnel need to maintain a high level of attention throughout the process, which significantly increases their workload.

[0003] A metering and detection device for pipeline fluid leakage with announcement number CN219433092U includes a weighing sensor, a ring frame, a fluid dripping vessel and a waste processing mechanism. The top of the weighing sensor is connected to the ring frame, and the fluid dripping vessel is clamped on the ring frame. The ring frame is provided with a waste processing mechanism. The fluid dripping vessel is driven to rotate automatically by the output shaft of the servo motor, so that the waste liquid after the measurement is completed is automatically collected, thereby improving the measurement efficiency and avoiding the situation where the measurement personnel have to stand and wait for a long time.

[0004] Although the metering and detection device for pipeline fluid leakage with announcement number CN219433092U has performed well in reducing the workload of metering personnel and improving detection efficiency, it still has shortcomings in waste liquid treatment. The secondary transportation and disposal of the waste liquid after collection not only increases costs, but also requires the cleaning of the two holding containers and the connection through tensioning belts, which is a time-consuming process.

The bolt rods are in interference fit with the positioning holes. The connecting plate is connected to the bolt rods, and two bolt rods between different bending brackets are connected by a connecting plate.

[0008] Preferably, a protective pad is further included. A protective pad is connected to the lower side of the top of the bending bracket for buffering the connection between the bending bracket and the pipeline.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with specific embodiments. It should also be noted that unless otherwise clearly specified and defined, terms such as "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Embodiment: A metering and detection device for pipeline leakage detection, as Figures 1 - 4 shown, includes a base 1, a bending bracket 2, a weighing device 3, a metering bucket 4, a limiting plate 5, a display 6, and a positioning component. The left and right ends of the base 1 are connected to the bending bracket 2. The weighing device 3 is installed on the base 1. The metering bucket 4 is placed on the weighing device 3. The limiting plate 5 is connected to the weighing device 3. The limiting plate 5 is arc-shaped and is in limiting cooperation with the bottom of the metering bucket 4. The display 6 is installed on the bending bracket 2. The display 6 is wirelessly connected to the metering bucket 4. The display 6 can control the metering bucket 4 and can display the reading of the metering bucket 4. A positioning component is provided at the top of the bending bracket 2 for restricting the position where the bending bracket 2 is connected to the pipeline, so as to ensure that all the waste liquid flowing out of the pipeline flows into the metering bucket 4.

[0022] As Figure 1 and Figure 4 shown, the positioning component includes a bolt rod 8 and a connecting plate 9. A plurality of positioning holes 7 are opened at the top of the bending bracket 2, and a plurality of bolt rods 8 are slidably connected to the top of the bending bracket 2. The bolt rods 8 are in interference fit with the positioning holes 7. The connecting plate 98 is connected to the bolt rods 8, and the two bolt rods 8 between the left and right bending brackets 2 are connected by a connecting plate 9.

[0023] The staff lifts the bending bracket 2 and hangs it on the pipe that needs to be leaked. The staff moves the bending bracket 2 left and right to align the leaking point with the metering bucket 4 to ensure that all the leaked waste liquid will drip into the metering bucket 4. In addition, for pipes of different diameters, it is necessary to plug and unplug the bolt rod 8 to ensure the front and rear position of the pipe. For smaller pipes, pull out the bolt rods 8 at the front and rear ends. The two can be pulled out together through the connecting plate 9, and the bolt rod 8 is inserted into the positioning hole 7 near the middle, thereby limiting the position where the pipe is connected to the bending bracket 2, ensuring that the leakage point of the pipe is located at the top of the metering bucket 4. Then the scale 3 is controlled by the display 6 to ensure that the scale 3 has been reset to zero before the measurement begins. The subsequent measurement process In the process, the display 6 displays the reading of the weighing device 3 in real time, and the recording interval is set through the display 6. The reading is registered at a certain interval time, so as to obtain the collection amount of waste liquid in each time interval, which can more clearly understand the situation of pipeline leakage. After the total measurement time is reached, the staff goes to the pipeline leakage measurement place, and judges whether the pipeline needs maintenance according to the data displayed and recorded by the display 6. Then, the bolt rod 8 is pulled out, the metering barrel 4 is removed, the collected waste liquid is processed, and the metering barrel 4 is cleaned, and the bending bracket 2 is removed to complete the inspection work. When the metering barrel 4 is placed, the limit plate 5 can ensure the position of the metering barrel 4, thereby ensuring the accuracy of the reading of the weighing device 3.

[0024] like Figure 1 and Figure 4 As shown, a protective pad 10 is also included. The protective pad 10 is connected to the lower side of the top of the bending bracket 2 to buffer the connection between the bending bracket 2 and the pipeline. The protective pad 10 on the bending bracket 2 can protect the pipeline and buffer the pressure between the bending bracket 2 and the pipeline bracket.

[0025] like Figure 1 As shown, it also includes a handle 12. The handle 12 is connected to the metering barrel 4 and is used to move the metering barrel 4. When taking out and putting in the metering barrel 4, the protruding handle 12 provides the staff with a better fulcrum, making it more convenient to dump and process the waste liquid in the metering barrel 4.

[0026] like Figure 1 As shown, it also includes universal wheels 13. A plurality of universal wheels 13 are connected to the bottom of the base 1 for moving the entire device. When moving the entire device, it can be moved through the universal wheels 13, which is more convenient.

[0027] like Figure 1As shown, it further includes a pull rod 11. The tops of two bent brackets 2 are jointly connected to the pull rod 11. When moving the bent bracket 2 in the vertical direction, in addition to applying force from both sides, once the bolt rod 8 is pulled out, the pull rod 11 can also be used to first pull it outwards, away from the pipeline, and then lift the bent bracket 2 upwards to remove the entire device from the pipeline. When pushing the entire device through the universal wheels 13, it is more convenient for the staff to exert force through the pull rod 11.

[0028] The bent bracket 2 is first suspended on the pipeline to be measured. The bolt rod 8 and the connecting plate 9 in the positioning component are flexibly adjusted to adapt to pipelines of different diameters, ensuring that the leakage point is directly opposite the measuring bucket 4. The setting of the protective pad 10 effectively buffers the contact pressure between the bracket and the pipeline, protecting the pipeline from damage. The weighing device 3 is installed on the base 1, on which the measuring bucket 4 is carried, and its position is fixed by the limiting plate 5 to ensure accurate measurement. The leaked waste liquid is accurately collected in the measuring bucket 4. At the same time, the display 6 is wirelessly connected to the weighing device 3 to display and record the weight of the waste liquid in real time, facilitating the monitoring of the leakage situation. After the measurement is completed, the staff can easily take out the measuring bucket 4 through the handle 12 to process the waste liquid, and use the pull rod 11 to assist in vertically moving the bent bracket 2. Finally, the entire device is conveniently moved to the next detection point through the universal wheels 13 under the base 1.

[0029] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
