Description

Technical Field

[0001] This invention relates to the field of cooling device technology, specifically to a water turbine circulating cooling device. Background Technology

[0002] In the field of hydropower, the turbine is the core equipment for converting water energy into electrical energy. During its operation, it continuously generates a large amount of heat. If the heat cannot be dissipated in time, it will directly affect the operating efficiency and service life of the equipment. Therefore, the circulating cooling device is an indispensable component of the turbine system. It is used to remove the heat from the equipment through the circulation of cooling water and ensure the long-term stable operation of the turbine.

[0003] In existing circulating systems, most filter components are fixed and lack automatic cleaning mechanisms. Impurities in the cooling water easily accumulate on the surface of the filter components, causing blockage of the water flow channels. Furthermore, the circulating pipeline does not form an efficient closed-loop design, which can easily lead to water flow turbulence or water waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water turbine circulating cooling device to solve the problems mentioned in the background art, such as the tendency for water flow turbulence or water resource waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water turbine circulating cooling device, comprising:

[0007] The turbine casing is located inside the water-cooled tower. A water outlet channel is provided at the bottom of the turbine casing. A water collection tank is installed at the bottom of the inner cavity of the water-cooled tower. A drain outlet is provided at the bottom of the water collection tank. A filter plate is installed on the upper surface of the water collection tank.

[0008] A scraper is disposed on the upper surface of the filter plate. A motor is installed in the inner cavity of the water cooling tower. A lead screw is coaxially mounted on the rotor of the motor. A moving block is mounted on the surface of the lead screw. The scraper is mounted on the surface of the moving block. A circulation pipe is installed between the water cooling tower and the water room.

[0009] Preferably, a storage box is installed at the bottom of the water-cooled tower, and the inner cavity of the storage box is provided with a storage slot;

[0010] The storage tank is made of water-corrosion-resistant and high-strength composite material, capable of withstanding long-term immersion in circulating cooling water without rust or structural deformation. The storage tank's interior features a flow-guiding structure adapted to the water flow direction, guiding the cooling water to flow smoothly and reducing turbulence caused by water flow impact, ensuring stable water intake for subsequent circulating pumps. The storage tank serves as a buffer energy storage unit for the circulating system. When fluctuations occur in the cooling water discharge from the water-cooling tower, the storage tank's temporary storage and replenishment functions maintain the system's water balance, preventing circulation interruptions or pressure anomalies due to sudden water volume changes. Simultaneously, it provides a continuous and stable water input to the circulating pumps, ensuring the continuity and reliability of the entire cooling cycle.

[0011] Preferably, a circulation pump is installed on the surface of the storage tank, and the outlet of the circulation pump is connected to the inlet of the circulation pipe;

[0012] The circulating pump adopts a specialized pump body structure adapted to the characteristics of circulating cooling water, possessing excellent anti-cavitation performance and low energy consumption advantages. The connection between the pump body and the storage tank employs a connection structure with superior sealing performance, effectively preventing cooling water leakage and ensuring sealing during operation. The circulating pump can adaptively adjust its operating status based on feedback signals from the temperature and flow rate of the cooling water within the system, achieving on-demand energy supply and avoiding unnecessary energy consumption. Its precise docking design with the circulation pipe reduces water flow resistance loss at the interface, improves cooling water delivery efficiency, and ensures that the cooled water can quickly return to the water room after cooling treatment, forming a highly efficient closed-loop circulation and further enhancing the overall cooling effect.

[0013] Preferably, each of the four corners of the upper surface of the filter plate is screwed with a first threaded rod, and the first threaded rod passes through the filter plate and is screwed onto the surface of the water collection tank.

[0014] The symmetrical screw-on design at the four corners creates a uniformly stressed and fixed structure between the filter plate and the water collection tank, ensuring the flatness and stability of the filter plate after installation and preventing displacement or deformation caused by water flow impact or scraper cleaning operations. This detachable screw-on design provides convenience for filter plate maintenance and replacement, allowing for quick removal of the filter plate for cleaning or replacement without complicated disassembly procedures, effectively reducing maintenance costs and downtime. At the same time, it ensures the sealing of the connection points, preventing cooling water leakage from gaps and ensuring the normal operation of the filtration function.

[0015] Preferably, diversion plates are installed on both sides of the surface of the water collection tank, and the diversion plates are all designed to be inclined. Collection boxes are installed on the surface of the water cooling tower at positions corresponding to the diversion plates.

[0016] The guide plate is made of a smooth material that does not easily attract impurities. Its tilt angle is optimized to fully utilize gravity to guide impurities smoothly down, preventing them from accumulating on the plate surface. The installation position and angle of the guide plate are precisely matched to the cleaning trajectory of the scraper, ensuring that impurities scraped by the scraper fall directly onto the surface of the guide plate and are then guided by the guide plate to collect in the collection box. The edges of the guide plate feature a smooth transition design to prevent scratching impurities or obstructing their flow, while also enhancing its structural strength. The collection box and the guide plate are precisely aligned to ensure that impurities fall efficiently into the collection box, achieving centralized collection and treatment of impurities. This prevents impurities from re-mixing into the cooling water, ensuring the cleanliness of the cooling water and reducing the risk of wear and blockage to subsequent circulation components.

[0017] Preferably, the collection ports of the collection boxes all penetrate the surface of the water-cooled tower, and the connection points of the collection boxes are all screwed with a second threaded rod;

[0018] The collection box features a flared opening design, expanding the impurity receiving range and improving collection efficiency. The edges of the collection opening are polished to prevent sharp edges from trapping impurities or scratching operators. A second threaded rod provides stable support for the collection box, ensuring it doesn't shift or fall off during operation. Its threaded connection structure provides excellent sealing, preventing cooling water leakage from the joints. The collection box is detachable; simply remove the second threaded rod to quickly remove it for easy cleaning of collected impurities. Operation is simple and convenient, requiring no complex tools. The interior of the collection box is treated with an anti-adhesion coating, reducing impurity adhesion to the box walls, simplifying cleaning, extending the collection box's lifespan, and ensuring long-term stable impurity collection.

[0019] Preferably, a slider is installed on the surface of the movable block, and a slide rail is installed on the inner wall of the water-cooled tower at a position corresponding to the slider;

[0020] The slider and slide rail ensure smooth and stable movement of the moving block along the rail, preventing jamming or deviation. The installation trajectory of the slide rail is parallel to the axis of the lead screw, providing precise guidance for the linear movement of the moving block and ensuring that the scraper moves evenly along the surface of the filter plate for thorough cleaning without any blind spots. The slider and moving block, as well as the slide rail and the inner wall of the water-cooling tower, all employ robust connection structures to ensure structural stability during transmission. These structures can withstand the driving force generated by the motor and the impact of water flow, effectively distributing the stress on the lead screw, reducing wear, extending the overall service life of the transmission components, and improving the operational reliability of the cleaning mechanism.

[0021] Preferably, each of the connecting sides of the scraper is equipped with a mounting plate, and a third threaded rod is screwed between the mounting plate and the moving block;

[0022] The mounting plate is made of high-strength, rigid material, providing a stable support for the scraper and ensuring it does not deform or break during cleaning operations. The third threaded rod allows for adjustable scraper height and fit; rotating it precisely adjusts the contact pressure between the scraper and the filter plate surface, ensuring effective removal of impurities while preventing excessive pressure that could wear the filter plate or scraper. The connections between the mounting plate, scraper, and moving block are all designed to fit together, ensuring a secure connection and smooth transmission. When the motor drives the moving block, power is precisely transmitted to the scraper, facilitating scraper replacement and maintenance. When the scraper becomes worn or damaged, it can be quickly replaced by removing the third threaded rod, ensuring continuous and stable cleaning performance.

[0023] Preferably, the surface of the water chamber is equipped with heat dissipation fins, and a fan is provided above the heat dissipation fins;

[0024] The heat dissipation fins are made of a metal with excellent thermal conductivity. Their densely arranged structure significantly increases the surface area of ​​the cooling chamber, rapidly transferring heat from the cooling water inside to the external environment. The heat dissipation fins are tightly fitted to the chamber surface to ensure efficient heat transfer and prevent poor contact from affecting heat dissipation. A fan positioned above the heat dissipation fins generates directional airflow, accelerating airflow across the fin surface, promoting rapid heat dissipation, and creating forced convection cooling for significantly improved efficiency. The fan's operation is adaptively adjusted based on the cooling water temperature; it increases fan speed when the water temperature is high and decreases or stops when the water temperature is low, achieving on-demand cooling and reducing energy consumption. The synergistic effect of the heat dissipation structure and the cooling chamber effectively controls the initial temperature of the cooling water, providing a fundamental guarantee for the cooling effect of the entire circulating cooling system.

[0025] Preferably, a mounting bracket is installed on the surface of the fan, and mounting feet are installed at the connection of the mounting bracket. A fourth threaded rod is screwed between the mounting feet and the water chamber.

[0026] The mounting bracket adopts a frame structure design, possessing excellent structural stability and load-bearing capacity. It can firmly support the fan, ensuring that the fan does not shake or shift during operation. The connection points between the mounting feet and the mounting bracket and water chamber have been optimized for stress distribution, effectively dispersing vibrations generated during fan operation, reducing the impact of vibrations on the water chamber and other components, and lowering operating noise. The fourth threaded rod provides convenient adjustment for the fan's installation height and level. By rotating the fourth threaded rod, the distance between the fan and the heat dissipation fins can be precisely adjusted, ensuring that airflow can efficiently act on the surface of the heat dissipation fins, optimizing heat dissipation. The threaded connection structure has good fixing reliability, resisting vibrations and external impacts during fan operation, ensuring long-term stable operation of the fan. It also facilitates the disassembly, maintenance, and repair of the fan, improving the ease of equipment maintenance.

[0027] Compared with the prior art, the present invention provides a water turbine circulating cooling device, which has the following beneficial effects:

[0028] This water turbine circulating cooling device uses a pump to deliver cooling water to the water-cooled tower via a delivery pipe. The turbine casing is located inside the water-cooled tower and can directly receive the cooling effect, improving the targeting and efficiency of the cooling. The cooled water flows precisely to the collection tank through the outlet channel for orderly collection. The filter plate on the collection tank can intercept impurities in the water flow, preventing impurities from affecting subsequent circulation or clogging components. The motor drives the lead screw to rotate, which moves the moving block and scraper on the surface of the filter plate, which can promptly remove the impurities accumulated on the filter plate and prevent the filter plate from clogging and causing water flow obstruction. The circulation pipe connects the water-cooled tower and the water room, which not only ensures the continuous and stable cooling effect of the water turbine, but also improves the reliability of the device operation and reduces the risk of failure caused by impurities clogging, water flow turbulence, or water waste.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Figure 5 The water-cooled tower 4 has a motor 10 installed inside its cavity. A lead screw 11 is coaxially mounted on the rotor of the motor 10. A movable block 12 is mounted on the surface of the lead screw 11, and a scraper 9 is mounted on the surface of the movable block 12. Please refer to [link / reference]. Figure 1 A circulation pipe 13 is installed between the water cooling tower 4 and the water room 1.

[0041] Water pump 3 on water chamber 1 delivers cooling water to water cooling tower 4 through delivery pipe 2. The turbine casing 5 is located inside water cooling tower 4 and can directly receive cooling, improving the targeting and efficiency of cooling. The cooled water flows precisely through water outlet channel 6 to water collection tank 7 for orderly collection. The filter plate 8 on water collection tank 7 can intercept impurities in the water flow, preventing impurities from affecting subsequent circulation or clogging components. The motor 10 inside water cooling tower 4 drives the lead screw 11 to rotate, driving the moving block 12 and scraper 9 to move on the surface of filter plate 8, which can promptly remove impurities accumulated on filter plate 8, preventing filter plate 8 from clogging and causing water flow obstruction. The drain outlet 71 at the bottom of water collection tank 7 facilitates the discharge of deposited impurities or excess water. Circulation pipe 13 connects water cooling tower 4 and water chamber 1, enabling the cooling water flow to be recycled, reducing water consumption. Through the coordinated cooperation of various structures, the system not only ensures the continuous and stable cooling effect of the turbine, but also improves the reliability of the device operation, reduces the risk of failure caused by impurity blockage, water flow turbulence, or water waste, and extends the service life of the device.

[0042] Please see Figure 2 A storage tank 15 is installed at the bottom of the water-cooled tower 4, and a storage slot 16 is opened in the inner cavity of the storage tank 15.

[0043] The storage tank 15 is made of a water-corrosion-resistant and high-strength composite material, capable of withstanding long-term immersion in circulating cooling water, preventing rust or structural deformation. The storage tank 16 has an internal flow guide structure adapted to the water flow direction, guiding the cooling water to flow smoothly, reducing turbulence caused by water flow impact, and ensuring stable water intake for the subsequent circulating pump 14. The storage tank 15 serves as a buffer energy storage unit for the circulating system. When the cooling water discharge from the water-cooling tower 4 fluctuates, the storage tank 16 temporarily stores and replenishes the water, maintaining the water balance within the system and preventing circulation interruption or pressure abnormalities due to sudden changes in water volume. Simultaneously, it provides a continuous and stable water input to the circulating pump 14, ensuring the continuity and reliability of the entire cooling cycle.

[0044] A circulation pump 14 is installed on the surface of the storage tank 15, and the outlet of the circulation pump 14 is connected to the inlet of the circulation pipe 13.

[0045] The circulating pump 14 adopts a dedicated pump body structure adapted to the characteristics of the circulating cooling water, possessing excellent anti-cavitation performance and low energy consumption advantages. The connection between the pump body and the storage tank 15 uses a connection structure with excellent sealing performance, effectively preventing cooling water leakage and ensuring sealing during operation. The circulating pump 14 can adaptively adjust its operating state based on the temperature and flow feedback signals of the cooling water in the system, achieving on-demand energy supply and avoiding ineffective energy consumption. Its precise docking design with the circulating pipe 13 reduces the resistance loss of water flow at the interface, improves the cooling water delivery efficiency, and ensures that the cooled water can quickly return to the water room 1 after cooling treatment, forming an efficient closed-loop circulation and further enhancing the overall cooling effect.

[0046] Please see Figure 4 Each of the four corners of the upper surface of the filter plate 8 is screwed with a first threaded rod 17, which passes through the filter plate 8 and is screwed onto the surface of the water collection tank 7.

[0047] The symmetrical screw-on design at the four corners creates a uniformly stressed and fixed structure between the filter plate 8 and the water collection tank 7, ensuring the flatness and stability of the filter plate 8 after installation and preventing displacement or deformation of the filter plate 8 due to water flow impact or cleaning operations by the scraper 9. This detachable screw-on design provides convenience for the maintenance and replacement of the filter plate 8, allowing for quick removal for cleaning or replacement without complicated disassembly procedures, effectively reducing maintenance costs and downtime. At the same time, it ensures the sealing of the connection points, preventing cooling water leakage from gaps and ensuring the normal operation of the filtration function.

[0048] Both sides of the surface of the water collection tank 7 are equipped with diversion plates 18, and the diversion plates 18 are all designed to be inclined. The surface of the water cooling tower 4 is equipped with collection boxes 19 at the corresponding positions of the diversion plates 18.

[0049] The guide plate 18 is made of a smooth material that does not easily attract impurities. Its tilt angle is optimized to fully utilize gravity to guide impurities to slide smoothly down, preventing them from accumulating on the plate surface. The installation position and angle of the guide plate 18 are precisely matched to the cleaning trajectory of the scraper 9, ensuring that the impurities scraped by the scraper 9 fall directly onto the surface of the guide plate 18, and are then guided by the guide plate 18 to collect in the collection box 19. The edges of the guide plate 18 are designed with a smooth transition to prevent scratching impurities or hindering their flow, while also enhancing its structural strength. The collection box 19 is precisely aligned with the guide plate 18, ensuring that impurities fall into the collection box 19 efficiently, achieving centralized collection and treatment of impurities, preventing impurities from re-mixing into the cooling water, ensuring the cleanliness of the cooling water, and reducing the risk of wear and blockage to subsequent circulation components.

[0050] Please see Figure 2 The collection ports of collection box 19 all penetrate the surface of water cooling tower 4. Please refer to [link / reference]. Figure 6 Each connection of the collection box 19 is screwed with a second threaded rod 191;

[0051] The collection port of the collection box 19 adopts a flared design to expand the impurity receiving range and improve impurity collection efficiency. The edges of the collection port are polished to prevent sharp edges from causing impurities to accumulate or scratch operators. The second threaded rod 191 provides a stable fixed support for the collection box 19, ensuring that it does not shift or fall off during equipment operation. Its threaded connection structure has good sealing performance, preventing cooling water leakage from the connection gaps. The collection box 19 adopts a detachable design; it can be quickly removed by disassembling the second threaded rod 191, facilitating the cleaning of impurities collected inside. The operation is simple and convenient, requiring no complicated tools. The interior of the collection box 19 is treated with an anti-adhesion coating to reduce impurities adhering to the box walls, simplifying cleaning and extending the service life of the collection box 19, ensuring long-term stable performance of the impurity collection function.

[0052] Please see Figure 5 A slider 20 is installed on the surface of the movable block 12, and a slide rail 21 is installed on the inner wall of the water cooling tower 4 at the corresponding position of the slider 20.

[0053] The slider 20 and slide rail 21 ensure smooth and stable movement of the moving block 12 along the slide rail 21, preventing jamming or deviation. The installation trajectory of the slide rail 21 is parallel to the axis of the lead screw 11, providing precise guidance for the linear movement of the moving block 12 and ensuring that the scraper 9 can move evenly along the surface of the filter plate 8, achieving comprehensive cleaning without any dead corners. The slider 20 and moving block 12, and the slide rail 21 and inner wall of the water cooling tower 4 are all connected by a robust structure, ensuring structural stability during transmission. This allows them to withstand the driving force generated by the motor 10 and the force from the water flow impact, effectively dispersing the force on the lead screw 11, reducing wear on the lead screw 11, extending the overall service life of the transmission components, and improving the operational reliability of the cleaning mechanism.

[0054] A mounting plate 22 is installed on the connecting side of the scraper 9, and a third threaded rod 23 is screwed between the mounting plate 22 and the moving block 12.

[0055] The mounting plate 22 is made of high-strength and rigid material, providing a stable mounting support for the scraper 9 and ensuring that the scraper 9 does not deform or break during cleaning operations. The third threaded rod 23 allows for adjustable mounting height and fit of the scraper 9. By rotating the third threaded rod 23, the contact pressure between the scraper 9 and the surface of the filter plate 8 can be precisely adjusted, ensuring that the scraper 9 can effectively remove impurities while avoiding excessive pressure that could cause wear to the filter plate 8 or the scraper 9. The connection points between the mounting plate 22, the scraper 9, and the moving block 12 are all designed to fit together, ensuring a firm connection and smooth transmission. When the motor 10 drives the moving block 12, the power can be precisely transmitted to the scraper 9, facilitating the replacement and maintenance of the scraper 9. When the scraper 9 becomes worn or damaged, it can be quickly replaced by removing the third threaded rod 23, ensuring the continuous and stable cleaning function.

[0056] Please see Figure 1 The surface of the water room 1 is equipped with heat dissipation fins 24, and a fan 25 is installed above the heat dissipation fins 24;

[0057] The heat dissipation fins 24 are made of a metal with excellent thermal conductivity. Their densely arranged structure significantly increases the heat dissipation area of ​​the water chamber 1, enabling rapid heat transfer from the cooling water inside the water chamber 1 to the external environment. The heat dissipation fins 24 are tightly fitted to the surface of the water chamber 1, ensuring efficient heat transfer and preventing poor contact from affecting heat dissipation. A fan 25 is positioned above the heat dissipation fins 24, generating directional airflow to accelerate airflow across the surface of the fins, promoting rapid heat dissipation and creating forced convection cooling, significantly improving heat dissipation efficiency. The fan 25's operation can be adaptively adjusted according to the temperature of the cooling water inside the water chamber 1; it increases fan speed when the water temperature is high and decreases or stops when the water temperature is low, achieving on-demand cooling and reducing energy consumption. The synergistic effect of the heat dissipation structure and the water chamber 1 effectively controls the initial temperature of the cooling water, providing a fundamental guarantee for the cooling effect of the entire circulating cooling system.

[0058] Please see Figure 7 A mounting bracket 26 is installed on the surface of the fan 25, and a mounting foot 27 is installed at the connection of the mounting bracket 26. A fourth threaded rod 28 is screwed between the mounting foot 27 and the water room 1.

[0059] Mounting bracket 26 adopts a frame structure design, possessing excellent structural stability and load-bearing capacity. It can firmly support the fan 25, ensuring that the fan 25 does not shake or shift during operation. The connection points between the mounting feet 27 and the mounting bracket 26 and water chamber 1 have been optimized for stress distribution, effectively dispersing the vibration generated by the fan 25 during operation, reducing the impact of vibration on the water chamber 1 and other components, and lowering operating noise. The fourth threaded rod 28 provides convenient adjustment for the installation height and level of the fan 25. By rotating the fourth threaded rod 28, the distance between the fan 25 and the heat dissipation fins 24 can be precisely adjusted, ensuring that airflow can efficiently act on the surface of the heat dissipation fins 24, optimizing the heat dissipation effect. The threaded connection structure has good fixing reliability, resisting the vibration and external impact of the fan 25 during operation, ensuring the long-term stable operation of the fan 25. It also facilitates the disassembly, maintenance, and repair of the fan 25, improving the ease of equipment maintenance.

[0060] In this design: the heat dissipation fins 24 on the surface of the water chamber 1 work in conjunction with the fan 25 to enhance initial heat dissipation. The water pump 3 delivers cooling water to the water cooling tower 4 via the delivery pipe 2. After the turbine casing 5 is directly cooled, the water flows through the outlet channel 6 into the water collection tank 7. The filter plate 8 intercepts impurities. The motor 10 drives the lead screw 11 to move the moving block 12 and scraper 9 along the slide rail 21, removing impurities from the surface of the filter plate 8 to the guide plate 18. The impurities slide into the collection box 19 through the inclined guide plate 18. The second threaded rod 191 fixes the collection box 19 to achieve detachable cleaning. The drain outlet 71 at the bottom of the water collection tank 7 discharges water... Sediment is removed, and the first threaded rod 17 fixes the filter plate 8 to ensure removability and maintenance. The circulation pump 14 draws the cooling water temporarily stored in the storage tank 16 in the storage tank 15 and returns it to the water room 1 through the circulation pipe 13 to form a closed loop circulation. The mounting plate 22 adjusts the pressure of the scraper 9 through the third threaded rod 23, and the slider 20 and the slide rail 21 ensure smooth movement. The fourth threaded rod 28 adjusts the height of the mounting foot 27 to optimize the heat dissipation efficiency of the fan 25. The whole system achieves efficient circulation of cooling water, precise interception of impurities, stable operation of equipment and optimization of energy consumption through structural coordination, thereby extending the life of the device and reducing the risk of failure.
