Description
Technical Field
[0001] This utility model belongs to the field of water pipeline monitoring technology, and in particular relates to an installation device for a pipeline joint deformation monitoring instrument. Background Technology
[0002] In long-distance water transfer projects, large-diameter water pipelines play a crucial role. Common types of water pipelines include cast iron pipes, steel pipes, fiberglass pipes, concrete pipes, and prestressed steel cylinder concrete pipes. These pipelines are connected in various ways, including welding, socket welding, bonding, and flange connections. Among these connection methods, the pipe joints of welded, socket, and bonded connections are critical parts of the entire pipeline system. Due to factors such as pressure fluctuations, temperature changes, alterations in geological conditions, and third-party construction, pipe joints may deform, leading to leaks. Therefore, the stability of pipe joints is crucial for the safe operation of the entire pipeline system. To ensure the stability of pipe joints, monitoring joint deformation is particularly important. Currently, permanent joint deformation monitoring is mainly achieved through sensors such as displacement gauges or joint gauges, but different pipe materials present numerous challenges during sensor installation. For example, cast iron and steel pipes require the removal of external anti-rust coatings and the fixing of sensor supports by welding; while fiberglass and concrete pipes typically use bonding to fix sensor supports after surface cleaning. The former damages the integrity of the anti-rust coating, while the latter places higher demands on the durability of the adhesive material.
[0003] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0030] like Figure 1 , Figure 2 As shown, the installation device for a pipe joint deformation monitoring instrument provided by this utility model includes a base 1, a cable tie tensioning device without a groove 2, a cable tie tensioning device with a groove 3, a tensioning bolt 4, a base fixing screw for the tensioning device 5, a cable tie fixing screw 6, a sensor clamp 7, a sensor clamp fixing screw 8, and a cable tie 9.
[0031] Base 1 measures 150×150×20mm (length×width×height) and is made of stainless steel. It has two M6 sensor clamp fixing holes in the center and four M8 cable tie tensioning device fixing holes on each side. Cable tie tensioning device 2 (without groove) is L-shaped, measuring 40×40×30mm (length×width×height) and 10mm thick, made of stainless steel. Its bottom surface has two φ8.2mm holes in the center, six φ6mm threaded holes on each side, and a φ12.2mm through hole in the center of the side. Cable tie tensioning device 3 (with groove) is L-shaped, measuring 60×40×30mm (length×width×height) and 10mm thick, made of stainless steel. Its bottom surface has a strip-shaped groove in the center, measuring [length×width...]. The sensor clamp measures 50×8mm, with six φ6mm threaded holes on both sides and a φ12.2 through hole in the middle of the side. The tensioning bolt 4 is an M12 bolt, 120mm in length. The base fixing screw 5 of the tensioning device is an M8 screw, made of stainless steel. The strapping fixing screw 6 is an M6 screw, made of stainless steel. The sensor clamp 7 is composed of two symmetrical upper and lower parts, with a combined length×width×height of 120×20×100mm. It has a φ25 hollow circle in the middle and is made of stainless steel. The sensor clamp fixing screw 8 is an M6 screw, made of stainless steel. The strapping 9 is the cross-sectional length of the water pipe, 40mm wide and 3-5mm thick, made of carbon fiber composite material.
[0032] The installation device of this utility model first places the base 1 at the monitoring positions at both ends of the pipe joint. The base 1 is made of stainless steel, which has high strength and corrosion resistance, and can remain stable during long-term use. During installation, the fixing holes of the base are used to connect the cable tie tensioning device 2 without a groove and the cable tie tensioning device 3 with a groove. The cable tie tensioning device 2 without a groove is fastened to the base by an M8 screw 5 and is in a locked state, while the cable tie tensioning device 3 with a groove can be finely adjusted along the groove, which plays a role in tightening and locking, so as to achieve precise installation.
[0033] After the cable tie tensioning device is installed, the cable tie 9 is secured using both screwless and screw-equipped sliding groove tensioning devices. The cable tie 9 is made of high-strength carbon fiber composite material, capable of withstanding vibrations and deformations that may occur during long-term pipeline operation. The cable tie is fastened to the cable tie tensioning devices 2 and 3 by the cable tie fixing screws 6, and symmetrically tightened by the tensioning bolts 4, ensuring a tight fit between the base 1 and the outer wall of the pipeline, thus guaranteeing the stability of the system installation.
[0034] The sensor clamp 7 consists of two symmetrical upper and lower parts, which are securely mounted to the center of the base 1 using sensor clamp fixing screws 8. The sensor clamp has a φ25mm perforated hole in the center, which can be used to fix monitoring instruments such as gap gauges or displacement gauges. The design of the sensor clamp allows the sensor to be accurately aligned with the measurement point at the pipe joint, ensuring the stability and reliability of data acquisition.
[0035] After installation, the pipeline joint deformation monitoring instrument is securely fixed by the sensor clamp 7 and monitors the displacement and deformation of the joint in real time during pipeline operation. The stable structure formed by the base 1 and the cable tie tensioning devices 2 and 3 ensures that the monitoring instrument does not shift or loosen during long-term operation, improving measurement accuracy. When the pipeline experiences minor deformation at the joint due to temperature changes, pressure fluctuations, or geological changes, the joint gauge or displacement gauge can accurately record data, providing reliable deformation trend analysis and a scientific basis for pipeline maintenance and safety assessment.
[0036] like Figure 3 , Figure 4 As shown, the installation device for the two sets of pipeline joint deformation monitoring instruments is a ring-shaped device installed on both sides of the joint of the water supply pipeline being measured. In practice, the lengths of different binding straps can be adjusted to accommodate pipelines of different circumferences; multiple bases can be distributed on the same ring-shaped joint to install multiple measuring sensors, with the overall layout in a series structure to measure the joint deformation at different locations; the height of the sensor clamps can be adjusted to accommodate joints of different heights; and the diameter of the hollow circle in the sensor clamps can be adjusted to accommodate sensors with different outer diameters.

Install two sets of cable tie locking devices 2 without screw sliding grooves and cable tie locking devices 3 with screw sliding grooves on both sides of the placed base 1. During installation, the cable tie locking devices 2 without screw sliding grooves should be in a locked state, while the cable tie locking devices 3 with screw sliding grooves should be in a freely sliding state.
[0039] Step S2: Two cable ties 10 are wrapped around the water supply pipe and fixed to the cable tie locking device 2 without screw sliding groove and the cable tie tensioning device 3 with sliding groove by the cable tie fixing screws 6.
[0040] Step S3: Use two tensioning device fixing screws 5 to connect the two sets of cable tie locking devices 2 without screw sliding grooves and cable tie tensioning devices 3 with sliding grooves in series respectively, and use the tensioning device fixing screws 5 to symmetrically tighten the two cable ties 9, so that the base 1 is in the original position and firmly pressed.
[0041] Step S4: Use sensor clamp fixing screw 8 to fix sensor clamp 7 to the middle of base 1.
[0042] Step S5: Repeat the above operation at the other end corresponding to the pipe joint to complete the installation of another set of pipe joint deformation monitoring instrument installation device.
[0043] Step S6: After the installation device for the pipe joint deformation monitoring instrument at both ends of the pipe joint is installed, fix both ends of the displacement gauge or joint gauge onto the sensor clamp 7 respectively. The operation is complete.
