Description

Technical Field

[0001] This utility model belongs to the field of marine pipeline technology, specifically, it relates to a marine pipeline clamp monitoring and anti-loosening device. Background Technology

[0002] As a core component of ship power plants and auxiliary systems, the ship's pipeline system is responsible for transporting key media such as fuel oil, lubricating oil, and cooling water.

[0003] However, in practical applications, traditional clamp devices generally suffer from the problem of gradual loosening of the connection structure due to periodic stress caused by vibration transmission, fluid pressure pulsation, and temperature changes. This may lead to leakage of the medium transmitted in the pipeline, resulting in abnormal equipment shutdown and, in severe cases, loss of power of the ship. In narrow waterways or in bad sea conditions, the risk of such failures getting out of control is extremely high, and it may also cause secondary disasters such as fire and environmental pollution.

[0004] To address the aforementioned issues, this application proposes a device for monitoring and preventing loosening of ship pipeline clamps. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a monitoring and anti-loosening device for ship pipeline clamps to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for monitoring and preventing loosening of pipe clamps in marine pipelines includes a pipe body, a flange on the outer wall of the pipe body, a retaining ring snapped onto the outer wall of the flange, a compression spring fixedly connected to the inner wall of the retaining ring, a movable block fixedly connected to the end of the compression spring away from the retaining ring, an inclined angle on the outer wall of the flange, an inclined angle on the side of the movable block near the flange, and the inclined angle of the movable block matching the inclined angle on the flange, an ear block fixedly connected to the outer wall of the retaining ring, an installation groove on the outer wall of the ear block, a button-type sensor fixedly connected to the ear block through the installation groove, and the sensing surface of the button-type sensor fitting against the outer wall of the ear block.

[0008] Preferably, a limiting block is fixedly connected to the inner sidewall of the retaining ring, and a limiting groove is formed at one end of the moving block near the inner sidewall of the retaining ring. The outer sidewall of the limiting block fits into the inner sidewall of the limiting groove. By setting the limiting block and the limiting groove, it is convenient to restrict the movement direction of the moving block and avoid the angle of the moving block changing during the movement.

[0009] Preferably, a retaining seat is fixedly connected to the outer wall of the retaining ring, a movable ring is slidably connected to the outer wall of the pipe body, a pull rod is rotatably connected to the outer wall of the movable ring, and a slot is opened at the end of the pull rod away from the movable ring. The slot engages with the retaining seat. By setting the retaining seat, movable ring, pull rod, and slot, it is convenient to pull the retaining ring, thereby improving the stability of the retaining ring.

[0010] Preferably, the outer wall of the movable ring is threaded with a threaded rod, and a rubber pad is rotatably connected to one end of the threaded rod near the flange. By setting the threaded rod and the rubber pad, the position of the movable ring can be restricted, and displacement of the movable ring can be avoided during use.

[0011] Preferably, a knob is fixedly connected to the end of the threaded rod away from the rubber pad. The knob is located on the side of the moving ring away from the retaining ring. By setting the knob, it is convenient for the operator to rotate the threaded rod.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This ship pipeline clamp monitoring and anti-loosening device, through the coordinated use of a clamp ring, a compression spring, a moving block, a flange, an ear block, a mounting groove, and a button-type sensor, facilitates the application of pre-tightening force to the pipeline body, increases the friction between the pipeline body and the clamp ring, and prevents the clamp ring from loosening due to factors such as vibration and changes in pipeline pressure, thereby improving the stability of the connection. At the same time, the compression spring facilitates adaptive adjustment of the position of the moving block, compensating for the gap caused by loosening and preventing further aggravation of loosening.

[0013] The retaining ring, movable ring, pull rod, groove, threaded rod, rubber pad, and knob facilitate the restriction of its position and distribute the force on the retaining ring. This prevents excessive concentrated force on any part of the retaining ring during long-term use, ensuring that the force is evenly distributed across all parts of the retaining ring, reducing the risk of local overload, and thus minimizing the possibility of wear and fatigue damage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A device for monitoring and preventing loosening of ship pipeline clamps includes a pipeline body 1, which is divided into two parts. Flanges 5 are provided on the outer walls of both parts of the pipeline body 1. A retaining ring 2 is clamped to the outer walls of the two flanges 5. A compression spring 3 is fixedly connected to the inner wall of the retaining ring 2. Several compression springs 3 are arranged in a circular array on the inner wall of the retaining ring 2. A movable block 4 is fixedly connected to the end of the compression spring 3 away from the retaining ring 2. Four movable blocks 4 are provided, located on the inner walls of the two retaining rings 2 on both sides. The outer wall of the flange 5 is inclined at an angle. The side of the movable block 4 closest to the flange 5 is also inclined at an angle that matches the inclination angle on the flange 5. Ear blocks 8 are fixedly connected to the outer wall of the retaining ring 2. Four ear blocks 8 are provided. Blocks 8 are located at both ends of the two retaining rings 2 and are positioned correspondingly. Taking one set of ear blocks 8 as an example, an installation groove 9 is provided on the outer wall of one of the ear blocks 8. A button-type sensor 10 is fixedly connected to the ear block 8 through the installation groove 9. The button-type sensor 10 is of model Blansen B102, with an outer diameter of 20mm and a height of 11mm. Its principle adopts metal foil strain technology. When pressure is applied to the sensor, the elastic body undergoes elastic deformation, and the metal foil strain gauge pasted on the surface of the elastic body also deforms accordingly, causing its resistance value to change. Through the measuring circuit, the change in resistance is converted into an electrical signal output, thereby completing the conversion from pressure to electrical signal, so that the staff can perform subsequent processing, storage and analysis. The button-type sensor 10 is located inside the installation groove 9, and the sensing surface of the button-type sensor 10 is attached to the outer wall of the other ear block 8.

[0022] During use, when the retaining ring 2 is tightened, the compression spring 3 pushes the moving block 4 towards the inner wall of the retaining ring 2. Since both the moving block 4 and the flange 5 have inclined surfaces and are positioned correctly, when the retaining ring 2 is tightened, the moving block 4 initially compresses the flange 5. This process generates continuous pressure on the flange 5, thus applying a pre-tightening force to the connection of the pipe body 1. This pre-tightening force increases the friction between the retaining ring 2 and the pipe body 1, preventing the retaining ring 2 from loosening due to vibration, changes in pipe pressure, etc., thereby improving the stability of the connection. Simultaneously, because... With the presence of the compression spring 3, when the main body of the pipeline 1 undergoes slight deformation or displacement due to thermal expansion and contraction, or fluctuations in medium pressure, the moving block 4 can adaptively adjust its position and pressure under the action of the compression spring 3. When the distance between the two lugs 8 changes due to the loosening of the retaining ring 2, the pressure on the button sensor 10 located between the two lugs 8 changes. Furthermore, the button sensor 10 converts the pressure change into an electrical signal and transmits it to the back-end system, making it easy for operators to observe and detect and repair problems with the retaining ring 2 as soon as possible.

[0023] Reference Figure 3 The inner wall of the retaining ring 2 is fixedly connected to a limiting block 6. There are four limiting blocks 6, which are distributed in a circular pattern on the inner wall of the retaining ring 2. The moving block 4 has a limiting groove 7 at one end near the inner wall of the retaining ring 2. The number of limiting grooves 7 corresponds to the number of limiting blocks 6. The outer wall of the limiting block 6 fits into the inner wall of the limiting groove 7. When the retaining ring 2 is tightened, the moving block 4 moves along the direction of the limiting block 6 to prevent the angle of the moving block 4 from changing during the movement.

[0024] Reference Figure 1 and Figure 4 The outer wall of the retaining ring 2 is fixedly connected to a retaining seat 11. Multiple retaining seats 11 are provided and are arranged in a circumferential array on the outer wall of the retaining ring 2. The outer wall of the pipe body 1 is slidably connected to a moving ring 12. The outer wall of the moving ring 12 is rotatably connected to a pull rod 13. The number of pull rods 13 corresponds to the number of retaining seats 11. Taking one pull rod 13 as an example, a slot 14 is opened at the end of the pull rod 13 away from the moving ring 12. The slot 14 is engaged with the retaining seat 11.

[0025] Reference Figure 1 and Figure 4The outer wall of the moving ring 12 is threaded with a threaded rod 15. Taking one side of the retaining ring 2 as an example, there are four threaded rods 15. Each of the four threaded rods 15 is rotatably connected to a rubber pad 16 near one end of the flange 5. The side of the four rubber pads 16 near the flange 5 is in contact with the outer wall of the flange 5. As the threaded rod 15 rotates, the moving ring 12 gradually moves away from the flange 5, thereby pulling the pull rod 13 and stabilizing the retaining ring 2. This prevents the retaining ring 2 from bearing excessive concentrated force in a certain part, so that the force is evenly distributed in all parts of the retaining ring 2, reducing the risk of local overload and thus reducing the possibility of wear and fatigue failure.

[0026] Reference Figure 1 and Figure 4 A knob 17 is fixedly connected to the end of the threaded rod 15 away from the rubber pad 16. The number of knobs 17 corresponds to the number of threaded rods 15. The knob 17 is located on the side of the moving ring 12 away from the retaining ring 2. The outer wall of the knob 17 is provided with a protrusion to facilitate the operator to rotate the threaded rod 15 through the knob 17.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
