Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline monitoring equipment, and specifically relates to a pipeline safety monitoring device. Background Technology

[0002] In pipeline safety monitoring, sensors such as plate gauges and joint gauges are widely used to monitor changes in the condition of the connection between two adjacent pipe bodies to ensure the safe operation of the pipeline; the condition of the connection between the two pipe bodies includes deformation, displacement and / or stress changes.

[0003] In the existing technology, sensors such as steel plate gauges and gap gauges are usually fixed directly to the pipe body by welding. This installation method can ensure that the sensors such as steel plate gauges and gap gauges are stably installed on the pipe body.

[0004] However, for non-metallic pipes and some metallic pipes, such as reinforced concrete pipes, prestressed (self-stressed) concrete pipes, prestressed steel cylinder concrete pipes (PCCP pipes), and ductile iron pipes, when installing sensors such as plate gauges and gap gauges, it is necessary to pre-embed welded structures on the outer wall of the pipe for fixing the plate gauges and gap gauges. However, the pre-embedding of the welded structures will damage the structure of the pipe, making the pipe prone to deformation, and may lead to water leakage or even pipe burst at the welded parts, which seriously affects the operational safety of the pipeline. Utility Model Content

[0006] To solve the above problems, this utility model is achieved through the following technical solution:

[0008] The clamp assembly is a ring structure. Two clamp assemblies are respectively fastened onto two interlocking pipe bodies, and the joint of the two pipe bodies is located between the two clamp assemblies.

The axis of the through hole is perpendicular to the plane where the ear plate is located. When the two arc-shaped plates are fastened to the tube body, the ear plates on the two arc-shaped plates are opposite each other. The locking bolt passes through the through hole on the opposite ear plates in sequence and is connected to the nut to fix the sleeve assembly.

[0015] To better realize this utility model, the above structure is further optimized by providing a pad layer on the concave surface of the arc plate to increase the friction between the arc plate and the tube.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In the embodiments of this application, such as Figures 1 to 4 As shown, the pipeline safety monitoring device includes a monitoring component 1 and two clamping components 2; wherein,

[0036] The clamp assembly 2 is a ring structure. The two clamp assemblies 2 are respectively fastened to the two interlocking pipe bodies 5. That is, after the clamp assembly 2 is fitted onto the pipe body 5, the position of the clamp assembly 2 will not change and can always remain synchronized with the pipe body 5. The joint of the two pipe bodies 5 is located between the two clamp assemblies 2.

[0037] The two ends of the monitoring component 1 are respectively connected to two sleeve components 2, and are used to monitor the relative position information of the two sleeve components 2 in order to obtain the status information of the connection between the two pipe bodies 5.

[0038] See Figure 2When installing the pipeline safety monitoring device, the staff can install the two clamp components 2 on the two pipe bodies 5 that are connected to each other, and then lock and fix the clamp components 2 so that the position of the clamp components 2 is consistent with the position of the pipe body 5.

[0039] Then, the two ends of the monitoring component 1 are respectively connected to the two clamp components 2, making the installation of the pipeline safety monitoring device more convenient. In this embodiment, the two ends of the monitoring component 1 can be installed and fixed on the clamp components 2 by welding or bolt fastening, so that the monitoring component 1 does not need to be directly installed on the pipe body 5. Therefore, the installation of the monitoring component 1 will not damage the structure of the pipe body 5, and can avoid the pipe body 5 from deformation, leakage, or pipe bursting due to the direct installation of the monitoring component 1 or the pre-embedded welding structure for welding and fixing the monitoring component 1. This ensures that the operation of the pipeline is not affected by the installation of the pipeline safety monitoring device.

[0040] It is worth noting that the pipe body 5 mentioned in this utility model refers to the component used to form the main body of the pipe, which can be selected according to different materials, diameters, lengths and thicknesses depending on the application and environment.

[0041] In some embodiments, see Figure 4 The aforementioned clamp assembly 2 includes a locking bolt 23 and two arc-shaped plates 21; wherein,

[0042] Both ends of the arc plate 21 are provided with ear plates 22. The free end of the ear plate 22 extends away from the middle of the arc plate 21, and the ear plate 22 is provided with a through hole. The axis of the through hole is perpendicular to the plane where the ear plate 22 is located.

[0043] When the two arc-shaped plates 21 are fastened onto the pipe body 5, the ear plates 22 on the two arc-shaped plates 21 are aligned with each other. The locking bolts 23 pass through the through holes on the two opposing ear plates 22 and are connected to the nuts, thereby fixing the clamp assembly 2. Preferably, the radius of the arc-shaped plate 21 matches the radius of the outer wall of the pipe body 5, and the arc-shaped plate 21 has a semi-circular arc structure. When the two arc-shaped plates 21 are fastened onto the pipe body 5, the ear plates 22 on the two arc-shaped plates 21 are aligned with each other. The locking bolts 23 pass through the through holes on the two aligned ear plates 22 and are connected to the nuts, thereby fixing the clamp assembly 2.

[0044] In some embodiments, the concave surface of the aforementioned arc plate 21 is provided with a pad 25 for increasing the friction between the arc plate 21 and the tube body 5. When the two arc plates 21 are fastened to the tube body 5, the pad 25 can fill the gap between the arc plate 21 and the tube body 5, increase the contact area between the arc plate 21 and the tube body 5, and increase the friction between the arc plate 21 and the tube body 5, so as to avoid the sleeve assembly 2 sliding along the axis of the tube body 5 or rotating around the axis of the tube body 5, which would cause the data monitored by the detection assembly to be inaccurate.

[0045] In some embodiments, the outer side wall of the above-mentioned clamp assembly 2 is provided with a mounting part 24, the mounting parts 24 on the two clamp assemblies 2 are positioned correspondingly, and the two ends of the monitoring component 1 are respectively connected to the mounting parts 24 of the two clamp assemblies 2.

[0046] In some embodiments, there are multiple mounting parts 24, which are arranged circumferentially around the sleeve assembly 2 at equal intervals. The number of monitoring components 1 is equal to the number of mounting parts 24, and the ends of the monitoring components 1 are installed on the multiple mounting parts 24 one by one, so as to realize the monitoring of the status information of multiple circumferential connection points of the pipe body 5, thereby improving the monitoring accuracy of the pipeline safety monitoring device.

[0047] Preferably, the mounting part 24 is an "L"-shaped plate structure. One plate of the mounting part 24 is welded and fixed to the sleeve assembly 2. The plane of the other plate of the mounting part 24 is parallel to the end face of the pipe body 5. That is, the axis of the pipe body 5 is perpendicular to the plane of the other plate of the mounting part 24. The plate is provided with a through hole. The end of the monitoring component 1 can pass through the through hole and be connected to the nut to realize the installation of the monitoring component 1, so as to make the installation of the pipeline safety monitoring device more convenient.

[0048] In some embodiments, see Figure 1 and Figure 3 The pipeline safety monitoring device also includes a cover 3, which covers the monitoring component 1 to prevent the monitoring component 1 from becoming inaccurate or damaged due to interference from the external environment. The aforementioned external environmental interference includes dust, rain, mechanical collisions, etc. The cover 3 can effectively protect the monitoring component 1 and improve the service life of the monitoring component 1.

[0049] In some embodiments, the outer side wall of the cover 3 is provided with fasteners 31, and the cover 3 is welded and fixed to the sleeve assembly 2 by the fasteners 31, so that the connection of the cover 3 is more stable.

[0050] In some embodiments, monitoring component 1 is a steel plate gauge or a crack gauge;

[0051] When monitoring component 1 is a steel plate, it can monitor the relative position information of the two sleeve components 2 to obtain information on the relative deformation, relative displacement and stress change of the two pipe bodies 5.

[0052] When the monitoring component 1 is used for gap measurement, it can monitor the relative position information of the two sleeve components 2 to obtain the relative deformation and relative displacement information of the two pipe bodies 5.

[0053] In some embodiments, see Figure 3 The pipeline safety monitoring device also includes a flange sleeve 4, which is fitted at the connection of the two pipe bodies 5 to wrap the joint of the two pipe bodies 5, provide support and reinforcement for the joint, prevent the pipe bodies 5 from being damaged by external forces, and extend the service life of the pipeline.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
