Description

Technical Field

[0001] This utility model relates to the field of antifouling technology for seawater pipelines, and more specifically to an ultrasonic anti-marine organism device for seawater pipelines. Background Technology

[0002] In seawater transportation scenarios such as seawater desalination, ship cooling systems, and coastal power plant circulating water systems, seawater pipelines are in long-term contact with seawater, making their inner walls prone to the growth of marine organisms such as shellfish, algae, and bacteria. The attachment and growth of these organisms reduces the pipeline's cross-sectional area and increases water flow resistance, directly reducing seawater transportation efficiency. At the same time, the metabolic products and dead remains of these organisms accelerate the corrosion process of the pipeline's inner wall, significantly shortening its service life. In severe cases, this can lead to pipeline blockages, related equipment malfunctions, and other safety hazards, adversely affecting the stable operation of the seawater transportation system.

[0003] Currently, the mainstream technical solution for preventing marine organism fouling in seawater pipelines is ultrasonic cleaning. This method involves equidistantly arranged transducers on the outside of the pipeline, utilizing the cavitation effect, mechanical vibration, and thermal effect of ultrasound to disrupt the living environment of marine organisms, thereby achieving the purpose of preventing fouling. It has advantages such as convenient installation, stable antifouling effect, and no pollution of seawater quality, and is suitable for various types of seawater transmission pipelines. However, the existing transducer fixing method mostly uses clamps and tie bolts for direct fastening. This structure has obvious defects in practical applications: on the one hand, the operation of adjusting the spacing of the transducers during installation is cumbersome and consumes manpower and time; on the other hand, the subsequent disassembly, replacement, and maintenance of the transducers also require a lot of time, resulting in poor maintenance convenience. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultrasonic anti-marine organism device for seawater pipelines to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an ultrasonic anti-marine organism device for seawater pipelines, comprising a pipeline body, a clamp sleeved on the outer surface of the pipeline body, transducers equidistantly mounted on the clamp, and an ultrasonic generator electrically connected to the transducers. The clamp has equidistantly spaced positioning holes on its surface, and a fixed seat is equidistantly slidably connected to the outer surface of the clamp. The transducer is fixedly mounted on the surface of the fixed seat, and a slot is formed through the surface of the fixed seat. The outer surface of the clamp is inserted into the slot. A silicone disc is fixedly mounted on the side of the fixed seat, and a positioning and pressurizing component is installed at the center of the fixed seat. Airbags are fixedly connected to the upper and lower walls of the slot. The output end of the silicone disc is connected to the input end of the positioning and pressurizing component.

[0006] Furthermore, the positioning and pressurizing assembly includes a sliding groove formed inside the fixed base. A sliding block is longitudinally and slidably connected inside the sliding groove. A positioning rod is fixedly connected to the bottom of the sliding block. The outer surface of the positioning rod is inserted into the inside of the positioning hole. A silicone elastic block is fixedly connected to the top center of the sliding block. A connecting pipe is fixedly connected inside the fixed base. The inside of the silicone disc is connected to the bottom of the sliding groove through the connecting pipe. A connecting rod is fixedly connected to the bottom of the sliding block. A sealing plate is fixedly connected to the end of the connecting rod. A limiting rod is fixedly connected to the upper surface of the sealing plate. A limiting groove is formed inside the fixed base. A vent pipe is fixedly connected inside the fixed base. The bottom of the limiting groove is connected to the inside of the airbag through the vent pipe.

[0007] Furthermore, the airbag is under high pressure inside, and the surface of the airbag abuts against the outer surface of the clamp.

[0008] Furthermore, steel balls are equidistantly mounted inside the fixed seat, with the surface of the steel balls extending to the outside of the fixed seat and the surface of the steel balls rollingly connected to the surface of the pipe body.

[0009] Furthermore, the silicone disc is hollow inside and under high pressure inside. A sealing ring is fixedly installed on the outer surface of the sliding block. The outer surface of the positioning rod is slidably and sealingly connected to the inside of the fixed seat. The end of the positioning rod is arc-shaped.

[0010] Furthermore, the outer surface of the connecting rod is slidably and sealed inside the fixed seat, a sealing ring is fixedly installed on the outer surface of the sealing plate, and the top ends of the sliding groove and the limiting groove are both in a non-sealed state.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model achieves rapid adjustment and positioning of the transducer spacing through a sliding connection structure between the fixed seat and the clamp, in conjunction with a positioning and pressurizing component. Pressing the silicone disc releases the locking of the positioning rod to the clamp positioning hole, allowing the fixed seat to slide freely along the clamp. After release, the silicone elastic block drives the positioning rod to automatically reset and reconnect, eliminating the need to disassemble bolts. This significantly simplifies the spacing adjustment operation during installation, saving manpower and time. Furthermore, during subsequent maintenance, only the pressing and unlocking action is required to slide and disassemble the fixed seat, significantly improving the convenience of transducer replacement and maintenance. This solves the pain points of cumbersome operation and low maintenance efficiency of traditional clamp fastening methods.

[0013] 2. This utility model achieves dual fixation of the fixed seat and clamp through the linkage design of the positioning and pressurizing component and the airbag, resulting in stronger stability. After the positioning rod is inserted into the positioning hole to complete the initial positioning, the sealing plate moves down with the sliding block, causing the airbag to inflate and tightly press against the surface of the clamp. The elastic pressure of the airbag increases the friction between the fixed seat and the clamp, preventing the fixed seat from shifting due to vibration during use. At the same time, the steel balls inside the fixed seat roll into contact with the surface of the pipe body, ensuring the fit of the clamp during installation and reducing the frictional resistance during the sliding adjustment of the fixed seat. This balances installation flexibility and operational stability. Furthermore, the ultrasonic antifouling method does not pollute seawater quality, ensuring the efficient and stable operation of the seawater transportation system. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] An ultrasonic anti-marine organism device for seawater pipelines includes a pipeline body 1, a clamp 2 sleeved on the outer surface of the pipeline body 1, a transducer 3 equidistantly mounted on the clamp 2, and an ultrasonic generator 6 electrically connected to the transducer 3. The clamp 2 has positioning holes 5 equidistantly opened on its surface, and a fixing seat 4 is equidistantly slidably connected to the outer surface of the clamp 2. The transducer 3 is fixedly mounted on the surface of the fixing seat 4. A slot 41 is opened through the surface of the fixing seat 4, and the outer surface of the clamp 2 is inserted into the inside of the slot 41. A silicone disc 7 is fixedly installed on the side of the fixing seat 4. A positioning and pressurizing component 8 is installed at the center of the inside of the fixing seat 4. Airbags 9 are fixedly connected to the upper and lower walls of the slot 41. The output end of the silicone disc 7 is connected to the input end of the positioning and pressurizing component 8.

[0022] Specifically, the positioning and pressurizing component 8 includes a sliding groove 81 inside the fixed base 4. A sliding block 82 is longitudinally and slidably connected inside the sliding groove 81. A positioning rod 85 is fixedly connected to the bottom of the sliding block 82. The outer surface of the positioning rod 85 is inserted into the positioning hole 5. A silicone elastic block 84 is fixedly connected to the top center of the sliding block 82. A connecting pipe 83 is fixedly connected inside the fixed base 4. The inside of the silicone disc 7 is connected to the bottom of the sliding groove 81 through the connecting pipe 83. A connecting rod 86 is fixedly connected to the bottom of the sliding block 82. A sealing plate 88 is fixedly connected to the end of the connecting rod 86. A limiting rod 810 is fixedly connected to the upper surface of the sealing plate 88. A limiting groove 87 is opened inside the fixed base 4. A vent pipe 89 is fixedly connected inside the fixed base 4. The bottom of the limiting groove 87 is connected to the inside of the airbag 9 through the vent pipe 89.

[0023] In this implementation scheme, the multi-component collaborative design of the positioning and pressurization assembly 8 realizes the linkage function of positioning and pressurization: the sliding block 82 drives the positioning rod 85 to insert into the positioning hole 5 to complete the initial positioning, and at the same time drives the sealing plate 88 to move through the connecting rod 86, so that the pressure change in the limiting groove 87 is transmitted to the airbag 9 through the vent pipe 89, realizing the inflation of the airbag 9. This not only ensures the accurate positioning of the fixed seat 4 and the clamp 2, but also provides power support for the pressurization of the airbag 9, making the linkage of the dual fixing structure smoother and improving the overall operational stability of the device.

[0024] Specifically, the airbag 9 is under high pressure inside, and the surface of the airbag 9 is against the outer surface of the clamp 2.

[0025] In this embodiment, the airbag 9 is under high pressure and its surface is against the outer surface of the clamp 2. The elastic pressure generated by the high pressure increases the friction between the fixing seat 4 and the clamp 2, effectively preventing the fixing seat 4 from shifting due to factors such as pipeline vibration and water flow impact during the use of the device. This further strengthens the connection stability between the fixing seat 4 and the clamp 2, ensuring that the transducer 3 always maintains the preset distance, and ensuring the uniformity and stability of the ultrasonic anti-marine organism effect.

[0026] Specifically, steel balls 10 are equidistantly mounted inside the fixed seat 4, and the surface of the steel balls 10 extends to the outside of the fixed seat 4. The surface of the steel balls 10 is rolledly connected to the surface of the pipe body 1.

[0027] In this embodiment, the steel ball 10 inside the fixing seat 4 rolls in contact with the surface of the pipe body 1. On the one hand, it can help adjust the position when the clamp 2 is installed, so that the clamp 2 fits the outer surface of the pipe body 1 better and ensures the installation accuracy. On the other hand, when the fixing seat 4 slides along the clamp 2 to adjust the spacing, it converts the sliding friction into rolling friction, which greatly reduces the frictional resistance and makes the sliding adjustment of the fixing seat 4 more effortless and smooth, taking into account both installation flexibility and fit stability.

[0028] Specifically, the silicone disc 7 is hollow inside and is under high pressure inside. A sealing ring is fixedly installed on the outer surface of the sliding block 82. The outer surface of the positioning rod 85 is slidably connected to the inside of the fixed seat 4. The end of the positioning rod 85 is arc-shaped.

[0029] In this embodiment, the hollow and high-pressure design of the silicone disc 7 allows for rapid pressure transmission through the connecting pipe 83 during pressing, driving the sliding block 82 to move precisely and enabling the positioning rod 85 to unlock quickly. The sealing ring on the outer surface of the sliding block 82 and the sealing sliding connection of the positioning rod 85 ensure the sealing of the sliding groove 81, preventing pressure leakage from affecting the operational sensitivity. The arc-shaped design at the end of the positioning rod 85 reduces jamming when it mates with the positioning hole 5, allowing the positioning rod 85 to be inserted into or removed from the positioning hole 5 more smoothly, thus improving the smoothness of the adjustment operation.

[0030] Specifically, the outer surface of the connecting rod 86 is slidably connected to the inside of the fixed seat 4, the outer surface of the sealing plate 88 is fixedly installed with a sealing ring, and the top of the sliding groove 81 and the limiting groove 87 are both in a non-sealed state.

[0031] In this embodiment, the sealing sliding connection between the connecting rod 86 and the sealing plate 88 ensures the sealing between the sliding groove 81 and the limiting groove 87, avoids leakage during pressure transmission, and ensures accurate and controllable inflation and deflation of the airbag 9. The non-sealed top of the sliding groove 81 and the limiting groove 87 can balance the internal air pressure, making the sliding block 82 and the sealing plate 88 slide more smoothly, avoiding the impact of air pressure blockage on the linkage response speed of the positioning and pressurizing component 8, and ensuring the rapid realization of device adjustment and fixing actions.

[0032] The working principle and usage process of this utility model are as follows: In use, multiple fixing seats 4 are inserted onto the outer surface of the clamp 2, and then the clamp 2 is fixedly connected to the outer surface of the pipe body 1. At this time, the surface of the steel ball 10 abuts against the outer surface of the pipe body 1. When it is necessary to adjust the arrangement spacing of the transducers 3, the silicone disc 7 is pressed. The strong pressure inside the silicone disc 7 enters the bottom end of the sliding groove 81 through the connecting pipe 83. At this time, the sliding block 82 drives the positioning rod 85 to slide upward. The positioning rod 85 disengages from the inside of the positioning hole 5. When the sliding block 82 slides upward, it drives the connecting rod 86 and the sealing plate 88 to slide upward. At this time, the pressure at the bottom end of the limiting groove 87 is reduced. The pressure gradually decreases to a negative pressure state. At this time, the airbag 9 is deflated and does not contact the outer surface of the clamp 2. The fixing seat 4 can slide freely on the outer surface of the clamp 2. After sliding to the specified position, the pressure on the silicone disc 7 is stopped. Through the elasticity of the silicone elastic block 84, the sliding block 82 drives the positioning rod 85 to slide down and inserts the positioning rod 85 into the corresponding positioning hole 5 to achieve positioning between the fixing seat 4 and the clamp 2. When the sliding block 82 slides down, the connecting rod 86 drives the sealing plate 88 to slide down. At this time, the airbag 9 inflates and abuts against the surface of the clamp 2, improving the stability between the fixing seat 4 and the clamp 2.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
