Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and in particular to a marine heat load regulating device. Background Technology

[0002] During navigation, the main engine and auxiliary equipment of a ship generate a large amount of heat, which needs to be effectively managed through a heat load regulation system to ensure the safe operation of the equipment. The heat load regulation system usually relies on a three-way thermostatic valve to precisely control the flow rate and direction of the cooling medium, thereby achieving stable temperature regulation. The cooling medium used by ships, whether seawater or river water, contains silt, aquatic organisms, and suspended particulate impurities. As these impurities flow through the pipeline, they continuously impact and adhere to the valve core and inner cavity of the three-way thermostatic valve. Over time, this can cause jamming of the valve's moving parts or blockage of the passage, eventually leading to the malfunction of the three-way thermostatic valve, which cannot respond to changes in heat load in a timely manner, posing a threat to the safe operation of the ship's main engine.

[0003] Meanwhile, ships sail at sea for extended periods, and their piping systems are constantly exposed to the high-salt-spray, high-humidity marine atmosphere. This environment has a strong electrochemical corrosive effect on metal components, especially flanges, welds, or threaded connections of the delivery pipes. These connections become weak points for corrosion due to stress concentration or material differences. Over time, the connections will weaken due to corrosion, leading to leakage of the cooling medium. This not only wastes resources but also causes insufficient system pressure, which in turn affects the normal functioning of heat load regulation.

[0004] Existing ship heat load regulating devices often neglect comprehensive protection against two key issues in their structural design: internal blockage of the three-way temperature control valve and corrosion at external pipe connections. They lack an integrated structure to simultaneously address both internal and external failure risks.

[0005] Therefore, this utility model proposes a ship heat load regulating device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of ship heat load regulating devices, such as the easy clogging of the three-way temperature regulating valve by impurities in the cooling medium and the easy corrosion of the delivery pipe connection in a high salt spray environment, which leads to the instability of system operation, this utility model aims to provide a ship heat load regulating device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a ship heat load regulating device, including a three-way temperature regulating valve and a conveying pipe connected to the three-way temperature regulating valve; and a filter mechanism installed on the inner wall of the conveying pipe.

[0008] The filtration mechanism includes a filter screen fixedly connected to the inner wall of the conveying pipe, and a fixing ring located inside the filter screen is also fixed to the inner wall of the conveying pipe.

[0009] Furthermore, a blade is rotatably connected to the fixed ring, a connecting rod is fixedly connected to one side of the blade, a fixed bracket is fixedly connected to the end of the connecting rod away from the blade, a scraper is installed on the fixed bracket, and the free end of the fixed bracket is rotatably connected to the fixed ring. In this way, the blade, connecting rod, fixed bracket and scraper together constitute a cleaning assembly that can rotate synchronously.

[0010] Preferably, the ship heat load regulating device further includes a protective mechanism installed on the outer wall of the delivery pipe connection; the protective mechanism includes a slotted block and a fixing ring respectively fixed on opposite sides of the delivery pipe connection; a corrugated pipe is fixedly connected to the outer wall of the fixing ring, and a threaded block is rotatably connected to the end of the corrugated pipe away from the fixing ring, and the threaded block is threadedly connected to the slotted block.

[0011] Preferably, the inner wall of the slotted block is provided with a threaded groove for guiding and cooperating with the threaded block; a sealing ring is also installed inside the slotted block, and the sealing ring is located between the threaded block and the slotted block.

[0012] Preferably, the corrugated pipe is an axially expandable tube.

[0013] Preferably, the scraping edge of the scraper remains in contact with the inner wall of the filter screen.

[0014] Preferably, the fixing ring is coaxially disposed inside the filter screen and provides rotational support for the blades and the fixing bracket.

[0015] Preferably, the connecting rod is fixedly connected to the middle of the right side of the outer wall of the blade; the scraper is installed in the middle of the fixed bracket.

[0016] Preferably, the corrugated pipe is fixedly connected to the left side of the outer wall of the fixing ring; the threaded block is rotatably connected to the left side of the outer wall of the corrugated pipe.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the filter device is easily clogged due to the accumulation of impurities, which leads to the failure of the three-way temperature control valve. It achieves the effect of effectively filtering impurities in the water while automatically cleaning the filter screen and preventing clogging, thereby ensuring the long-term stable operation of the heat load regulation system.

[0018] 2. This utility model solves the problem in the prior art that the connection of the conveying pipe is easily corroded due to long-term exposure to the high salt spray environment at sea, which poses a risk of leakage and affects the service life of the pipeline. By assembling a retractable corrugated pipe cover on the outside of the connection of the conveying pipe and using a protective mechanism of threaded blocks and slotted blocks for locking and sealing, the connection of the conveying pipe is completely isolated from the corrosive environment, effectively preventing electrochemical corrosion and significantly improving the reliability and durability of the pipeline connection.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 6This utility model provides a ship heat load regulating device, which aims to solve the technical problems in the existing ship heat load regulating system, such as the easy clogging of the three-way temperature regulating valve 1 by impurities in the water and the easy corrosion of the pipeline connection in a high salt spray environment, which leads to the unstable operation of the system.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, the ship's heat load regulating device includes a three-way temperature regulating valve 1 and a delivery pipe 4 connected to the three-way temperature regulating valve 1. To ensure the stable operation of the three-way temperature regulating valve 1, a filter mechanism 2 is installed on the inner wall of the delivery pipe 4, and a protective mechanism 3 is installed on the outer wall of the connection of the delivery pipe 4. (Refer to...) Figure 4 and Figure 5 The filtration mechanism 2 includes a filter screen 204 fixedly connected to the inner wall of the conveying pipe 4. A fixing ring 201 is also fixed to the inner wall of the conveying pipe 4, located inside the filter screen 204. The fixing ring 201 is coaxially disposed inside the filter screen 204. A blade 202 is rotatably connected to the fixing ring 201. A connecting rod 203 is fixedly connected to the middle of the right side of the outer wall of the blade 202. A fixing bracket 206 is fixedly connected to the end of the connecting rod 203 away from the blade 202. A scraper 205 is installed in the middle of the fixing bracket 206, and a fixing support is also provided. The other end of the frame 206 is rotatably connected to the fixing ring 201. In this way, the paddle 202, connecting rod 203, fixing bracket 206 and scraper 205 together constitute a cleaning assembly that rotates synchronously with the water flow. The fixing ring 201 provides rotational support for the paddle 202 and the fixing bracket 206. When the cleaning assembly rotates, the edge of the scraper 205 keeps in contact with the inner wall of the filter screen 204 to scrape off impurities attached to the inner wall of the filter screen 204, thereby achieving self-cleaning of the filter screen 204 and avoiding clogging.

[0024] Please refer to Figure 3 and Figure 6The protective mechanism 3 includes a slotted block 301 and a fixing ring 305 fixed to opposite sides of the connection of the conveying pipe 4. Specifically, the slotted block 301 is fixedly connected to the left side of the connection of the outer wall of the conveying pipe 4, and the fixing ring 305 is fixed to the right side of the connection of the outer wall of the conveying pipe 4. A corrugated pipe 304 is fixedly connected to the left side of the outer wall of the fixing ring 305. The corrugated pipe 304 is an axially expandable pipe. A threaded block 303 is rotatably connected to the right side of the outer wall of the corrugated pipe 304, which is away from the fixing ring 305. A threaded groove 306 is provided on the inner wall of the slotted block 301 for guiding and cooperating with the threaded block 303. A sealing ring 302 is also installed in the slotted block 301. Located between the threaded block 303 and the slotted block 301, during installation, the bellows 304 is first stretched to extend axially and cover the entire connection of the conveying pipe 4. Then, the threaded block 303 is screwed into the threaded groove 306 of the slotted block 301. During the tightening of the threaded block 303, the bellows 304 is fixed in the extended state. At the same time, the end of the threaded block 303 will squeeze the sealing ring 302, deform under pressure and tightly fill all gaps, thereby forming a reliable seal between the slotted block 301 and the threaded block 303. This combination of the physical coverage of the bellows 304 and the threaded locking sealing structure can completely isolate the connection of the conveying pipe 4 from the external high salt spray environment, effectively preventing corrosion.

[0025] As a preferred embodiment, to further clarify the structural layout and connection relationships of the components inside the filter mechanism 2, please continue to refer to... Figure 5 The fixing ring 201 of the filter mechanism 2 is coaxially set inside the filter screen 204 and provides stable support for the rotation of the cleaning component. The connecting rod 203 is fixedly connected to the middle of the right side of the outer wall of the paddle 202, while the scraper 205 is installed in the middle of the fixed bracket 206. This central connection and installation method helps to maintain the dynamic balance of the entire cleaning component during rotation, reduce vibration and wear, and ensure that the scraper 205 can evenly adhere to the inner wall of the filter screen 204 for scraping operations.

[0026] As another preferred embodiment, to further clarify the structural layout and connection relationships of the various components inside the protective mechanism 3, please continue to refer to... Figure 6 The bellows 304 is fixedly connected to the left side of the outer wall of the retaining ring 305, while the threaded block 303 is rotatably connected to the left side of the outer wall of the bellows 304. This connection configuration, with one end fixed and the other end rotating, allows the bellows 304 to rotate freely at the connection end with the threaded block 303 after being stretched to cover the connection point. This makes it easy for the user to screw the threaded block 303 into the threaded groove 306 of the slotted block 301 without causing the bellows 304 itself to twist or be damaged. This simplifies the installation operation and enhances the durability of the structure.

[0027] As a further optimization of the scraping effect of the filter mechanism 2, the edge of the scraper 205 is designed to maintain contact with the inner wall of the filter screen 204. The scraper 205 can be made of a wear-resistant material with a certain degree of elasticity, or it can be installed on the fixed bracket 206 by elastic elements such as springs, so as to ensure that even if slight wear occurs during long-term operation, the scraper 205 can continuously apply stable contact pressure to the inner wall of the filter screen 204, thereby ensuring that the effect of scraping impurities remains consistent.

[0028] As a further refinement of the sealing performance of the protective mechanism 3, the sealing ring 302 is preferably an elastic rubber ring with an O-shaped or rectangular cross section, which is pre-placed in the annular groove on the inner wall of the slotted block 301. When the threaded block 303 is screwed in, the end face of the threaded block 303 will uniformly press the entire annular surface of the sealing ring 302, producing radial and axial deformation, thereby reliably filling all potential gaps between the inner wall of the slotted block 301, the end face of the threaded block 303, and the outer wall of the delivery pipe 4, forming a three-dimensional sealing barrier.

[0029] Working principle: When the ship's heat load regulation system is running, the water that needs to be regulated flows through the delivery pipe 4 to the three-way temperature control valve 1. When the water flows through the filter mechanism 2 installed inside the delivery pipe 4, firstly, the silt, aquatic plants, and other larger particles in the water are intercepted by the filter screen 204, achieving preliminary purification of the water quality. At the same time, the continuous water flow will generate an impact force on the blade 202 set in front of the filter screen 204, driving the blade 202 to rotate around the axis of the fixed ring 201. Since the blade 202 is fixedly connected to the fixed bracket 206 through the connecting rod 203, and the entire cleaning assembly is rotatably connected to the fixed ring 201 with the blade 202 and the other end of the fixed bracket 206 as the fulcrum. Therefore, the rotation of the blade 202 will drive the connecting rod 203, the fixed bracket 206 and the scraper 205 installed on the fixed bracket 206 to rotate synchronously. During the rotation, the scraper 205, which is in contact with the inner wall of the filter screen 204, will continuously scrape the entire inner surface of the filter screen 204, removing the impurities intercepted by the filter screen 204 from the mesh, preventing the accumulation of impurities and clogging of the mesh. The scraped impurities will be concentrated with the water flow or settled in other positions in the pipeline, and can be cleaned periodically. Through this synergistic effect of the filter mechanism 2, this utility model uses the energy of the water flow itself to achieve the dual functions of filtration and self-cleaning, effectively solving the problem of blockage of the three-way temperature control valve 1 caused by the accumulation of impurities. For the protective mechanism 3 installed outside the connection of the conveying pipe 4, during installation or maintenance, the threaded block 303 can be unscrewed from the threaded groove 306 of the slotted block 301. At this time, the elastic bellows 304 can freely contract or extend. When protection is required, the bellows 304 is extended to a sufficient length to completely cover the entire connection area of ​​the conveying pipe 4. Then, the threaded block 303 is aligned with the threaded groove 306 of the slotted block 301 and tightened. During the tightening process, the threaded block 303 securely fixes the bellows 304 in the extended coverage position through the threaded connection. On the other hand, it will continuously squeeze the sealing ring 302 located inside the slotted block 301. The compressed sealing ring 302 undergoes elastic deformation and tightly fills all the fitting gaps, thereby forming a completely sealed protective layer at the connection of the conveying pipe 4. This protective layer can effectively isolate the connection from the high-salt and high-humidity marine air outside. Through this covering and sealing effect of the protective mechanism 3, this utility model solves the leakage and damage problems caused by the long-term exposure of the pipeline connection to the corrosive environment in the prior art, and ensures the long-term stable operation of the entire heat load regulation system.
