Description

Technical Field

[0001] This invention belongs to the field of marine technology, and more specifically, relates to a structure for preventing blockage of marine cooling pipes. Background Technology

[0002] Marine cooling systems are piping systems used to dissipate heat from ship equipment. They remove heat generated by main engines, auxiliary engines, and other equipment through seawater or freshwater circulation, preventing overheating and damage. This system is a crucial component of the marine propulsion system and is primarily used for cooling engine room equipment in various types of ships. During navigation, ships require water circulation to cool operating equipment. Over prolonged use, impurities can accumulate on the inner walls of the cooling equipment's filter cartridges, making it difficult to filter the cooling water and causing blockages in the pipes. In severe cases, pipes or joints may rupture due to overpressure, resulting in cooling water leaks.

[0003] Existing technology includes a designation titled "A Cooling Device and Ship," with publication number CN221563410U. This technology discloses a cooling device and ship, relating to the field of marine technology. The cooling device comprises: two sets of coolers, fixedly located on both sides of the ship's exterior near the stern, the coolers being below the waterline; and a connecting pipe for connecting the two sets of coolers. Coolant to be cooled enters one cooler chamber for initial cooling, then flows through the connecting pipe to the other cooler for secondary cooling, before being transported back to the ship's propulsion system. By establishing a loop with two connected coolers, the coolant only contacts the inner cavity of the cooler, reducing the requirements for corrosion and rust prevention of internal equipment and piping, preventing blockage and corrosion, and improving reliability. During navigation, the coolers are always in a flowing external water cooling environment, avoiding reduced cooling effect due to localized overheating of the external cooling water. Simultaneously, the symmetrical distribution of the coolers on both sides of the hull near the stern improves the ship's stability during navigation.

[0004] However, this technology does not address the technical issues and solutions of this application. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a ship cooling pipe anti-clogging structure that is simple in structure, can automatically trigger the cleaning mechanism to work without manual intervention, ensures that the pipeline is always in a state of high-efficiency filtration, avoids the risk of cooling efficiency reduction or equipment overheating due to blockage, and improves the working reliability of the cooling system, in order to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention relates to an anti-clogging structure for ship cooling pipes. A cleaning mechanism is installed inside the filter cylinder. The lower end of the retractable cable of the cleaning mechanism is fixedly connected to a fixing block. The retractable cable passes through the upper cover. An electric telescopic rod is fixedly connected to the lower end of the fixing block. A movable plate is fixedly connected to the telescopic end of the electric telescopic rod. A motor is fixedly connected to the lower surface of the movable plate. A cleaning disc is fixedly connected to the output shaft of the motor. A first movable rod is hinged to one side of the movable plate, and an extension plate is hinged to the other end of the first movable rod. A second movable rod is hinged to one side of the fixing block, and the other side of the second movable rod is hinged to the other side of the extension plate. When the movable plate moves up and down, it causes the first movable rod and the extension plate to unfold, allowing the rollers on the extension plate to adhere to the inner wall of the filter cylinder. This causes the cleaning mechanism to move up and down. When the motor rotates, it drives the cleaning disc to rotate, causing the cleaning mechanism to move from the upper part of the filter cylinder to the lower part, cleaning the impurities formed by the cooling medium accumulated on the inner wall of the filter cylinder.

[0007] The lower surface of the cover is fixedly connected to an outer shell, the drain outlet of the outer shell is fixedly connected to a drain pipe, and the outer surface of the drain pipe is fixedly connected to a control valve.

[0008] A control pipeline is fixedly connected to one side of the outer casing, and a differential pressure switch is fixedly connected to the middle of the control pipeline. The control pipeline is installed on the outer casing. A water inlet pipe is fixedly connected to the water inlet of the outer casing, and a water outlet pipe is fixedly connected to the water outlet of the outer casing. Both the water inlet pipe and the water outlet pipe are installed on the outer casing.

[0009] The inner bottom of the outer casing is provided with a limiting groove, and a filter cylinder is snapped into the inside of the limiting groove. A retractable cable passes through a section of the top cover and is connected to a retractor.

[0010] The cleaning disc is provided with a brush section on its side, which is attached to the inner wall of the filter cylinder.

[0011] The inner wall of the filter cylinder is provided with a spiral traction channel from top to bottom, and multiple guide posts are provided at intervals along the side of the cleaning disc. The guide posts are movably locked in the spiral traction channel.

[0012] Multiple extension plates are arranged around the fixed block. Each movable plate has multiple first movable rods hinged to one side, and the other end of each first movable rod is hinged to the corresponding side of the extension plate. Multiple second movable rods are hinged to one side of the fixed block, and the other side of each second movable rod is hinged to the corresponding other side of the extension plate.

[0013] The filter cylinder is provided with filter mesh holes that penetrate the filter cylinder body.

[0014] The upper part of the filter cartridge rests against the lower surface of the upper cover, and the upper cover is fixedly connected to the outer shell by bolts or buckles.

[0015] The diameter of the filter cartridge cross-section is smaller than the diameter of the outer shell cross-section, and the diameter of the cleaning disc is smaller than the diameter of the inner wall of the filter cartridge.

[0016] The working principle and beneficial effects of the technical solution adopted in this invention are as follows: The anti-clogging structure for ship cooling pipes described in this invention includes a filter cartridge installed inside the outer shell. The filter cartridge filters the passing water. Due to prolonged use, impurities accumulate on the inner wall of the filter cartridge, affecting water flow. Therefore, the anti-clogging structure for ship cooling pipes utilizes a cleaning mechanism. This cleaning mechanism employs a retractable cable, a fixed block, an electric telescopic rod, a movable plate, a first movable rod, an extension plate, a second movable rod, a motor, and a cleaning disc. The electric telescopic rod drives the movable plate to move, which, in conjunction with the hinged first movable rod, extension plate, and second movable rod, allows the extension plate to move up and down inside the filter cartridge under the influence of rollers. This enables the cleaning disc to thoroughly clean the inner wall of the filter cartridge, improving the filtration efficiency and achieving effective filtration of the cooling water. The anti-clogging structure of the ship's cooling pipeline uses the combined use of inlet pipe, outlet pipe, control pipeline, differential pressure switch, drain pipe, control valve and shell. The differential pressure switch in the control pipeline monitors the pressure difference across the filter cartridge in real time. When the pressure difference exceeds the set threshold, the cleaning mechanism is automatically triggered without manual intervention, ensuring that the pipeline is always in a high-efficiency filtration state and avoiding the risk of reduced cooling efficiency or overheating of equipment due to blockage. The working principle of this invention is as follows: Cooling water enters the interior of the outer casing through the inlet pipe. When the water flows through the filter cylinder, impurities are trapped by the filter cylinder. The filtered clean cooling water flows out from the outlet pipe and enters the cooling system for circulation. The differential pressure switch in the control pipeline monitors the pressure difference on both sides of the filter cylinder in real time. When the accumulation of impurities causes the pressure difference to exceed the set threshold, the differential pressure switch automatically triggers the cleaning mechanism. The electric telescopic rod starts and pushes the movable plate downward. The movable plate drives the hinged first and second movable rods to unfold. The extension plate expands outward under the action of the connecting rod. When it reaches the filter cylinder, it can move up and down inside the filter cylinder, so that the cleaning disc cleans the inner wall of the filter cylinder. The motor starts and drives the cleaning disc to rotate at high speed, scraping off the impurities on the inner wall of the filter cylinder. The telescopic cable moves up and down with the cleaning mechanism to ensure power supply throughout the process. When cleaning is not performed, the cleaning mechanism rises into the top cover, and the cleaned impurities settle to the bottom of the outer casing. The control valve opens, and the impurities are discharged from the system through the drain pipe. After the drain is completed, the control valve automatically closes, thus achieving the filtration of cooling water. Attached Figure Description

[0018] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 5As shown, this invention is an anti-clogging structure for ship cooling pipes. A cleaning mechanism 4 is installed inside the filter cylinder 3. A fixed block 402 is fixedly connected to the lower end of the retractable cable 401 of the cleaning mechanism 4. The retractable cable 401 movably passes through the upper cover 1. An electric telescopic rod 403 is fixedly connected to the lower end of the fixed block 402. A movable plate 404 is fixedly connected to the telescopic end of the electric telescopic rod 403. A motor 408 is fixedly connected to the lower surface of the movable plate 404. A cleaning disc 409 is fixedly connected to the output shaft of the motor 408. A first movable rod 405 is hinged to one side of the movable plate 404. One end of the fixed block 402 is hinged to one side of the extension plate 406, and the other side of the fixed block 402 is hinged to the second movable rod 407. The other side of the second movable rod 407 is hinged to the other side of the extension plate 406. When the movable plate 404 moves up and down, it drives the first movable rod 405 and the extension plate 406 to unfold, so that the roller 410 on the extension plate 406 fits against the inner wall of the filter cylinder 3, driving the cleaning mechanism 4 to move up and down. When the motor 408 rotates, it drives the cleaning disc 409 to rotate, driving the cleaning mechanism 4 to move from the upper part to the lower part of the filter cylinder 3 to clean the impurities formed by the cooling medium accumulated on the inner wall of the filter cylinder 3. The above structure proposes an improved technical solution to address the shortcomings of the prior art. In the structure, a filter cylinder is set inside the outer shell to filter the water. However, due to long-term use, impurities will accumulate on the inner wall of the filter cylinder, affecting the flow of water. Therefore, an anti-clogging structure for the ship's cooling pipes is set up, mainly through the cleaning mechanism. The cleaning mechanism of this ship's cooling pipe anti-clogging structure utilizes a retractable cable, a fixed block, an electric telescopic rod, a movable plate, a first movable rod, an extension plate, a second movable rod, a motor, and a cleaning disc. The electric telescopic rod drives the movable plate, which, in conjunction with the hinged first movable rod, extension plate, and second movable rod, allows the extension plate to move up and down inside the filter cartridge under the influence of rollers. This enables the cleaning disc to thoroughly clean the inner wall of the filter cartridge, improving its filtration efficiency and achieving effective cooling water filtration. The anti-clogging structure also incorporates an inlet pipe, outlet pipe, control pipe, differential pressure switch, drain pipe, control valve, and outer casing. The differential pressure switch in the control pipe monitors the pressure difference across the filter cartridge in real time. When the pressure difference exceeds a set threshold, the cleaning mechanism is automatically triggered without manual intervention, ensuring the pipes are always in a high-efficiency filtration state and preventing cooling efficiency reduction or equipment overheating risks caused by clogging.The working principle of this invention is as follows: Cooling water enters the interior of the outer casing 11 through the inlet pipe 5. When the water flows through the filter cylinder 3, impurities are trapped by the filter cylinder 3. The filtered clean cooling water flows out from the outlet pipe 6 and enters the cooling system for circulation. The differential pressure switch 8 in the control pipeline 7 monitors the pressure difference on both sides of the filter cylinder 3 in real time. When the accumulation of impurities causes the pressure difference to exceed the set threshold, the differential pressure switch 8 automatically triggers the cleaning mechanism 4, the electric telescopic rod 403 starts, and pushes the movable plate 404 downward. The movable plate 404 drives the hinged first movable rod 405 and second movable rod 407 to unfold, and the extension plate 406 is connected. The rod expands outward under its action. When it reaches the filter cylinder 3, it can move up and down inside the filter cylinder 3, allowing the cleaning disc 409 to clean the inner wall of the filter cylinder 3. The motor 408 starts, driving the cleaning disc 409 to rotate at high speed, scraping away impurities from the inner wall of the filter cylinder 3. The retractable cable 401 moves up and down with the cleaning mechanism 4 to ensure power supply throughout the process. When cleaning is not in use, the cleaning mechanism 4 rises into the upper cover 1, and the cleaned impurities settle to the bottom of the outer shell 11. The control valve 10 opens, and the impurities are discharged from the system through the drain pipe 9. After the drain is completed, the control valve 10 automatically closes, thus achieving the filtration of cooling water. The anti-clogging structure for ship cooling pipes described in this invention has a simple structure and can automatically trigger the cleaning mechanism to work without manual intervention, ensuring that the pipes are always in a high-efficiency filtration state, avoiding the risk of reduced cooling efficiency or equipment overheating due to blockage, and improving the reliability of the cooling system.

[0019] The lower surface of the upper cover 1 is fixedly connected to the outer shell 11, and the drain outlet of the outer shell 11 is fixedly connected to the drain pipe 9. The outer surface of the drain pipe 9 is fixedly connected to the control valve 10. In the above structure, the drain pipe 9 is installed on the outer shell 11, and the cleaned impurities settle at the bottom of the outer shell 11. The drain pipe 9 can be controlled to discharge impurities by the control valve 10 installed on the drain pipe 9.

[0020] A control pipe 7 is fixedly connected to one side of the outer casing 11, and a differential pressure switch 8 is fixedly connected to the middle of the control pipe 7. The control pipe 7 is installed on the outer casing 11. A water inlet pipe 5 is fixedly connected to the water inlet of the outer casing 11, and a water outlet pipe 6 is fixedly connected to the water outlet of the outer casing 11. Both the water inlet pipe 5 and the water outlet pipe 6 are installed on the outer casing 11. With the above structure, the differential pressure switch 8 can detect the pressure difference inside the outer casing 11 and control whether the cleaning mechanism 4 is activated to clean the inner wall of the filter cartridge 3. In this way, the operation of the cleaning mechanism 4 is automatically controlled.

[0021] The inner bottom of the outer casing 11 is provided with a limiting groove 2, and a filter cylinder 3 is engaged inside the limiting groove 2. A retractable cable 401 passes through a section of the upper cover 1 and connects to the retractor 12. In this structure, the limiting groove 2 is installed inside the outer casing 11, which can restrict the filter cylinder 3 to prevent it from becoming loose during filtration. The retractable cable 401 passes through the upper cover 1, which is installed on the outer casing 11. The filter cylinder 3 can be replaced by opening the upper cover 1. The retractable cable 401 is installed on the fixed block 402, which can provide power to the device. An electric telescopic rod 403 is installed inside the fixed block 402, which can push the movable plate 404 to move up and down. The retractor 12 is used to release and retract the retractable cable 401. When the cleaning mechanism moves downward, the retractor releases the retractable cable 401; when the cleaning mechanism moves upward, the retractor retracts the retractable cable 401.

[0022] The cleaning disc 409 has a brush section on its side, which fits against the inner wall of the filter cylinder 3. A spiral traction channel is arranged from top to bottom on the inner wall of the filter cylinder 3. Multiple guide posts 411 are spaced apart along the circumference of the cleaning disc 409, and the guide posts 411 are movably engaged within the spiral traction channel. In this structure, the spiral traction channel and guide posts 411 cooperate. When the motor 408 rotates, it drives the cleaning disc 409 to move up and down. When the motor 408 rotates in one direction, it drives the cleaning disc 409 downwards along the spiral traction channel, and the brush on the side of the cleaning disc 409 cleans impurities from the inner wall of the filter cylinder 3. When the motor 408 rotates in the other direction, it drives the cleaning disc 409 upwards along the spiral traction channel, and the cleaning mechanism 4 returns to its original position near the top cover.

[0023] Multiple extension plates 406 are arranged around the fixed block 402. Each movable plate 404 has multiple first movable rods 405 hinged to one side, and the other end of each first movable rod 405 is hinged to one side of the corresponding extension plate 406. Multiple second movable rods 407 are hinged to one side of the fixed block 402, and the other side of each second movable rod 407 is hinged to the other side of the corresponding extension plate 406.

[0024] The filter cylinder 3 is provided with filter mesh holes 410 that penetrate the cylinder body. In the above structure, the filter mesh holes filter the cooling water entering the filter cylinder, thus filtering out most of the impurities in the cooling water. Some impurities that enter the filter cylinder accumulate on the inner wall of the filter cylinder. After the equipment has been used for a period of time, the blockage can be removed by cleaning the inner wall of the filter cylinder.

[0025] The upper part of the filter cartridge 3 rests against the lower surface of the upper cover 1, and the upper cover 1 is fixedly connected to the outer shell 11 by bolts or clips. With this structure, the upper cover 1 can be easily installed and disassembled. The cross-sectional diameter of the filter cartridge 3 is smaller than the cross-sectional diameter of the outer shell 11, and the diameter of the cleaning disc 409 is smaller than the inner wall diameter of the filter cartridge 3. With this structure, the filter cartridge is installed inside the outer shell, and the cleaning disc is installed on the inner wall of the filter cartridge.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
