[0002] In the steel cord production process, a variety of liquids need to be transported through pipelines, such as sewage pipelines, electroplating liquid pipelines, coolant pipelines, soap liquid pipelines, etc. Once a pipeline leakage occurs, personnel are required to discover it before handling it, causing environmental pressure and economic losses, and subsequent processing is time-consuming and labor-intensive.

[0003] Usually, when the above pipeline leaks, workers usually discover the leaking liquid on the ground or find that the pumping speed does not meet the requirements. In both cases, the leak cannot be handled in time. This delayed treatment will cause more pollution and difficulties in subsequent cleaning. Therefore, timely detection of leaks is crucial and needs to be solved urgently. Utility Model Content

[0022] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1 As shown, the first aspect of the utility model proposes a pipeline leakage alarm device, including a liquid delivery pipeline 10, a support plate 20 and an alarm circuit 30, wherein the liquid delivery pipeline 10 is used to transport liquid media with conductive properties, such as electroplating liquid, coolant and soap solution used in steel cord production.

[0024] Furthermore, the support plate 20 is disposed below the liquid delivery pipeline 10 , and the support plate 20 is insulated from the liquid delivery pipeline 10 .

[0025] like Figure 1 As shown, the alarm circuit 30 includes a first electrode 31 and a second electrode 32 . The first electrode 31 is connected to the liquid delivery pipeline 10 and extends to the inside of the liquid delivery pipeline 10 to keep in contact with the delivered liquid medium. The second electrode 32 is connected to the support plate 20 .

[0026] Therefore, the alarm circuit 30 includes two branches. The first branch is along the first electrode 31 and the conductive liquid in the liquid delivery pipeline 10 , and the second branch is the second electrode 32 and the support plate 20 .

[0027] Among them, the alarm circuit 30 is used to provide voltage to the first electrode 31 and the second electrode 32, so that a voltage difference is formed between the first electrode 31 and the second electrode 32. When the liquid medium in the liquid delivery pipeline 10 continuously drips onto the surface of the support plate 20, the alarm circuit 30 is turned on and the alarm circuit 30 is triggered to generate an alarm signal.

[0028] Combination Figure 2 As shown, when a leak occurs in the liquid delivery pipeline 10, such as at the connection between two sections of the pipeline or at the valve or other parts, once the leaked conductive liquid drips onto the surface of the support plate 20 in strands or continuously, the two branches of the alarm circuit 30 form a closed loop, making the alarm circuit 30 conductive.

[0029] Optionally, the liquid delivery pipeline 10 and the support plate 20 are connected via a plurality of support rods 21 so that the liquid delivery pipeline 10 and the support plate 20 maintain a relative distance therebetween, and the support rods 21 are insulating rods.

[0030] In an optional embodiment, the support plate 20 is constructed as a flat plate structure, preferably made of a conductive material, such as a stainless steel plate.

[0031] The support plate 20 may also be made of a composite plate, for example, a stainless steel covering is provided on the surface of a plastic plate to make the surface conductive.

[0032] In this way, when a leak occurs in the liquid delivery pipeline 10 , the conductive liquid forms an electrical connection with the second electrode 32 on the surface of the support plate 20 , and the current is closed and conducted from the first electrode 31 - conductive liquid - support plate 20 - second electrode 32 .

[0033] The alarm circuit 30 includes a power supply and an alarm, wherein the power supply can be an AC or DC power supply, and the alarm can be an audible and visual alarm. When the alarm circuit 30 is closed, an audible and visual alarm can be realized.

[0034] In an optional embodiment, the support plate 20 is configured to have an arc-shaped upper surface, and is located below the liquid conveying pipeline 10 and arranged along the extension direction of the liquid conveying pipeline 10 .

[0035] In this way, when a leak occurs in the liquid delivery pipeline 10, the dripping conductive liquid will not leak out, thereby reducing the difficulty of handling after the leak.

[0036] Furthermore, in any axial cross section, the upper edge of the support plate 20 extends to exceed the lowest point of the liquid delivery pipeline 10 .

[0037] In this way, when the leakage speed of the liquid delivery pipeline 10 is slow and cannot reach continuous dripping, as long as the leakage amount is large enough, that is, the liquid level in the support plate 20 is higher than the lowest point of the liquid delivery pipeline 10, the conductive liquid also achieves conduction between the first electrode 31 and the second electrode 32.

[0038] In an optional embodiment, the support plate 20 is provided with a plurality of partitions along the length direction of the pipeline, so that each section of the support plate 20 forms a small-capacity cavity. In this way, if a leakage occurs, the conductive liquid in the cavity can quickly rise to a liquid level that can reach an alarm, so as to facilitate a timely alarm.

[0039] Furthermore, overflow grooves are provided between the multiple partitions to prevent the current partition from overflowing outwards. It should be understood that the height of the overflow groove is higher than the lowest point of the liquid delivery pipeline 10.

[0040] In another embodiment, Figure 3 As shown, in order to facilitate the location of the leakage point, the alarm circuit 30 includes a plurality of second electrodes 32, wherein a liquid delivery pipeline 10 is defined as a plurality of length segments along its length, each length segment of the liquid delivery pipeline 10 corresponds to a length segment of the support plate 20, and adjacent support plates 20 are insulated from each other, and the alarm circuit 30 includes an alarm connected to the second electrode 32.

[0041] In this way, multiple parallel circuits can be formed through this setting, and each leakage position corresponds to a circuit. When the liquid delivery pipeline 10 at the corresponding position leaks, the second electrode 32 corresponding to the leakage position is turned on, so an alarm occurs, and the alarm at the position sounds, which is helpful for the user to confirm the leakage position.

[0042] Furthermore, in order to process the pumped conductive liquid in time after the alarm, a delivery pump for delivering the liquid medium to the liquid delivery pipeline 10 is also included. When the alarm circuit 30 generates an alarm signal, the delivery pump stops pumping.

[0043] Furthermore, it also includes a valve for controlling the on-off of the liquid delivery pipeline 10. When the alarm circuit 30 generates an alarm signal, the valve is closed.

[0044] In the above-mentioned embodiment, the alarm circuit 30 is connected to the controller, and the delivery pump and the valve are used as actuators. After the alarm circuit 30 outputs an alarm signal to the controller, the controller can control the corresponding actuator to act. It should be understood that the priority of the delivery pump and valve actions can be set as needed. When the priority is higher, the action of the diameter alarm signal is given priority.

[0045] In combination with the above embodiments, the utility model can monitor whether the pipeline is leaking in real time online by setting a first electrode on the pipeline and a second electrode on the support plate under the pipeline. When the conductive liquid leaking from the pipeline continuously drips onto the support plate and the alarm circuit forms a closed loop, the alarm can be triggered. This alarm system works reliably, minimizes pipeline leakage, avoids environmental pressure and economic losses, and can be used for all conductive liquid transportation pipelines of the company. It has wide adaptability, a large application range, low operating and maintenance costs, and obvious economy.

A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
