Description

Technical Field

[0001] This invention belongs to the technical field of steam turbine cooling water tanks, specifically relating to a steam turbine cooling water distribution device that is easy to maintain. Background Technology

[0002] Steam turbines, as core power equipment in power plants and industrial production, generate a large amount of heat during operation. If this heat cannot be efficiently dissipated through the cooling water system, it will lead to excessively high temperatures in internal components, causing problems such as deterioration of material properties, seal failure, and reduced operating efficiency. In severe cases, it can even cause unit shutdown, resulting in huge economic losses. Therefore, the cooling water distribution device, as a key component of the steam turbine cooling system, directly affects the operational stability and service life of the steam turbine.

[0003] The core component of the cooling water distribution device is the cooling water distribution box. When a malfunction occurs inside the cooling water distribution box, it is difficult for operators to repair due to its small space. Usually, it needs to be disassembled for repair. However, existing cooling water distribution boxes are usually installed using bolts and other structures, which is very inconvenient to disassemble, requiring the removal of multiple bolts, which is time-consuming and laborious. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a turbine cooling water distribution device that facilitates maintenance. This device allows for the quick removal of the cooling water distribution box, making maintenance easier.

[0005] The turbine cooling water distribution device for easy maintenance according to an embodiment of the present invention includes: A distribution box, which is used for distributing cooling water; Mounting plate, the distribution box is slidably connected to the mounting plate in the vertical direction, the mounting plate is used for mounting the distribution box; The connecting part includes multiple connectors. At least one connector is provided between the left and right sides of the dispensing box and the mounting plate. The connector includes a slot and a block. The slot is opened on the mounting plate, and the block is disposed on the dispensing box. The block is used to insert into the slot to lock the dispensing box on the mounting plate. When the card block is inserted into the card slot, it locks the distribution box to the mounting plate. When the card block is removed from the card slot, it unlocks the distribution box from the mounting plate, so that the distribution box can be detached from the mounting plate.

[0006] The turbine cooling water distribution device in this invention, which facilitates maintenance, replaces the original bolt installation method with a connecting part. This eliminates the need to disassemble multiple bolts one by one, significantly reducing disassembly steps, saving maintenance time and labor costs, and solving the pain points of limited space and inconvenient maintenance operations associated with the distribution box. The locking and unlocking actions of the connecting parts are simple, and the sliding connection design facilitates quick placement and removal of the distribution box, allowing for easy operation even in confined spaces and improving maintenance efficiency. In the locked state, the cooperation between the locking block and the locking slot ensures the distribution box is securely installed without affecting its cooling water distribution function, indirectly guaranteeing the efficient operation of the turbine cooling system, thereby maintaining the turbine's operational stability and service life.

[0007] In some embodiments, the upper end of the card block is inserted into the card slot, and the middle section of the card block is rotatably connected to the dispensing box; Moving the lower end of the card block closer to the mounting plate allows the upper end of the card block to be removed from the card slot, facilitating the unlocking of the distribution box from the mounting plate.

[0008] In some embodiments, a first elastic member is connected between the lower end of the card block and the dispensing box. The first elastic member provides support to the lower end of the card block so that the upper end of the card block is held in the card slot.

[0009] In some embodiments, the connecting part further includes a linkage component, the linkage component including a rotating shaft rotatably disposed at the lower end of each of the locking blocks, a connecting rope fixedly connected between two adjacent rotating shafts, and a pull rope fixedly connected to the rotating shaft located at the lowest side. When the two pull ropes on both sides are pulled downwards, the pull ropes drive the lower end of the locking block to move closer to the mounting plate via the rotating shaft. At the same time, the rotating shaft drives the other locking blocks to move closer to the mounting plate via the connecting rope, so that multiple locking blocks are unlocked simultaneously.

[0010] In some embodiments, a handle is fixedly connected to the lower end of the pull rope, and the handle is provided with an anti-slip groove. The handle is used to facilitate the operator to pull the pull rope.

[0011] In some embodiments, the dispensing box and the mounting plate are slidably connected by a sliding part, the sliding part comprising: Multiple limiting plates are fixedly connected to the left and right sides of the mounting plate, and the limiting plates are used to limit the sliding trajectory of the distribution box. Multiple movable card sleeves are fixedly connected to the left and right sides of the distribution box, and each movable card sleeve corresponds to a limiting card plate. The movable card sleeve is slidably connected to the limiting card plate.

[0012] In some embodiments, the connector further includes a protective shell disposed on the movable card sleeve, and the card block is rotatably connected in the protective shell. The protective shell is used to protect the card block and prevent accidental contact.

[0013] In some embodiments, an auxiliary part is provided between the bottom of the dispensing box and the mounting plate, the auxiliary part comprising: A support plate, located below the mounting plate; An auxiliary plate, located between the support plate and the mounting plate; The second elastic element is located between the support plate and the auxiliary plate. The second elastic element is used to apply a downward force to the distribution box through the support plate to facilitate the disengagement of the distribution box from the mounting plate.

[0014] In some embodiments, the auxiliary part further includes a limiting post disposed on the support plate, the auxiliary plate being slidably sleeved on the limiting post, and the limiting post being used to install the support plate.

[0015] In some embodiments, a handle is fixedly connected to the top of the dispensing box, and the handle is used by the operator to pull the dispensing box. Attached Figure Description

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1-2 As shown, the turbine cooling water distribution device for easy maintenance according to an embodiment of the present invention includes a distribution box 1, a mounting plate 2, and a connecting part 3.

[0025] Distribution box 1 is used for distributing cooling water; The dispensing box 1 and the mounting plate 2 are slidably connected in the vertical direction, and the mounting plate 2 is used for the installation of the dispensing box 1; The connecting part 3 includes multiple connectors 31. At least one connector 31 is provided between the left and right sides of the dispensing box 1 and the mounting plate 2. The connector 31 includes a slot 311 and a block 312. The slot 311 is opened on the mounting plate 2, and the block 312 is provided on the dispensing box 1. The block 312 is used to insert into the slot 311 to lock the dispensing box 1 on the mounting plate 2. When the card block 312 is inserted into the card slot 311, it locks the distribution box 1 and the mounting plate 2. When the card block 312 is removed from the card slot 311, it unlocks the distribution box 1 and the mounting plate 2, so that the distribution box 1 can be removed from the mounting plate 2.

[0026] The turbine cooling water distribution device in this invention, which facilitates maintenance, replaces the original bolt installation method with a connecting part. This eliminates the need to disassemble multiple bolts one by one, significantly reducing disassembly steps, saving maintenance time and labor costs, and solving the pain points of limited space and inconvenient maintenance operations associated with the distribution box. The locking and unlocking actions of the connecting parts are simple, and the sliding connection design facilitates quick placement and removal of the distribution box, allowing for easy operation even in confined spaces and improving maintenance efficiency. In the locked state, the cooperation between the locking block and the locking slot ensures the distribution box is securely installed without affecting its cooling water distribution function, indirectly guaranteeing the efficient operation of the turbine cooling system, thereby maintaining the turbine's operational stability and service life.

[0027] Specifically, the distribution box slides up and down to engage with the mounting plate. The locking blocks on its left and right sides insert into corresponding slots on the mounting plate, directly fixing the distribution box to the mounting plate and ensuring stable cooling water distribution during turbine operation. When a fault occurs inside the distribution box 1 requiring maintenance, simply remove the locking block 312 from the slot 311 to release the lock between the distribution box 1 and the mounting plate 2. Then, slide the distribution box 1 up and down to remove it from the mounting plate 2 without needing to disassemble multiple fixing structures. After maintenance, slide the distribution box 1 along the mounting plate 2 to the corresponding position, allowing the locking block 312 to re-insert into the slot 311 and lock, thus completing the reset and restoring the cooling water distribution function.

[0028] Furthermore, two connectors 31 are symmetrically arranged on the left and right sides of the distribution box 1, and the two connectors 31 on the same side are spaced apart in the vertical direction.

[0029] The turbine cooling water distribution device in this embodiment of the invention, which is easy to maintain, forms four locking points that are symmetrical on the left and right and spaced vertically on the same side through the setting of four connecting parts. This creates a balanced force distribution layout, which avoids the distribution box from shifting or loosening due to cooling water impact or equipment vibration during operation, and improves installation stability.

[0030] Specifically, when the distribution box 1 slides up and down along the mounting plate 2, two symmetrically arranged locking blocks 312 (spaced vertically on the same side) on its left and right sides are respectively inserted into the four locking slots 311 on the mounting plate 2. The four locking points form a balanced force structure, firmly locking the distribution box 1 onto the mounting plate 2 and ensuring operational stability. For maintenance, simply remove the four locking blocks 312 from their corresponding slots 311 in sequence to release all locking points, and the distribution box 1 can be quickly removed along the sliding direction without disassembling the bolts. After maintenance, slide the distribution box 1 along the mounting plate 2 to the preset position, allowing the four locking blocks 312 to precisely insert into their corresponding slots 311, completing multi-point locking and restoring the coolant distribution function.

[0031] In some embodiments, such as Figure 2 As shown, the upper end of the card block 312 is inserted into the card slot 311, and the middle section of the card block 312 is rotatably connected to the dispensing box 1. By moving the lower end of the card block 312 closer to the mounting plate 2, the upper end of the card block 312 can be removed from the card slot 311, making it easier to unlock the dispensing box 1 and the mounting plate 2.

[0032] The turbine cooling water distribution device in this embodiment of the invention, which facilitates maintenance, utilizes the lever principle. Pushing the lower end of the locking block unlocks the upper end, eliminating the need for direct pulling or prying of the upper end. This reduces the force required, making it particularly suitable for operation in confined spaces. The unlocking action requires only the simple step of "pushing the lower end," requiring no additional tools and making it easier to operate than plug-and-play locking blocks, further shortening maintenance preparation time. After the upper end of the locking block naturally inserts into the slot, vibrations and cooling water impacts during operation will not easily cause the lower end to move, preventing accidental dislodgement and ensuring the stability of the locked state. The lever-like action disperses the force during unlocking, reducing hard friction and impact between the locking block and the slot, decreasing component wear, and extending the service life of the connecting parts.

[0033] Specifically, the middle section of the locking block 312 is rotatably connected to the distribution box 1 via a rotating shaft, and its upper end naturally inserts into the slot 311 of the mounting plate 2. Utilizing the weight of the locking block 312 itself or structural limiting, the upper end maintains a tight fit with the slot 311, firmly locking the distribution box 1 onto the mounting plate 2. For maintenance, push the lower end of the locking block 312 towards the mounting plate 2. Using the rotation fulcrum of the middle section, the upper end of the locking block 312 rotates outward from the slot 311 through leverage, quickly releasing the lock of a single locking point. After operating all locking blocks 312 in sequence, the distribution box 1 and mounting plate 2 are completely unlocked, and it can be removed along the sliding direction. After maintenance, slide the distribution box 1 along the mounting plate 2 to the preset position, release the lower end of the locking block 312 (or gently push it in the opposite direction), and the upper end of the locking block 312 automatically inserts into the corresponding slot 311 under the action of gravity or elastic restoring force, completing the locking of all points and restoring the coolant distribution function.

[0034] In some embodiments, such as Figure 2 As shown, a first elastic member 313 is connected between the lower end of the card block 312 and the distribution box 1. The first elastic member 313 is used to provide support force to the lower end of the card block 312 so that the upper end of the card block 312 is held in the card slot 311.

[0035] The turbine cooling water distribution device in this embodiment of the invention provides a continuous and stable pre-tightening force through the first elastic element, so that the upper end of the locking block and the locking slot are always tightly fitted, which completely solves the problem of "vibration loosening" that may occur when relying solely on gravity locking. Even if the turbine generates strong vibration or cooling water impact during operation, it can ensure that the distribution box is stably installed, indirectly ensuring the operational stability of the cooling system and the turbine.

[0036] Specifically, the middle section of the locking block 312 is rotatably connected to the distribution box 1, and the first elastic element 313 is connected between the lower end of the locking block 312 and the distribution box 1, always applying an outward supporting force (away from the mounting plate direction) to the lower end of the locking block 312. According to the lever principle, this supporting force will drive the upper end of the locking block 312 to press against the mounting plate 2, making it firmly embedded in the locking groove 311, forming an elastically pre-tightened locking structure to prevent the locking block from loosening due to vibration or impact. When maintenance is required, press the lower end of the locking block 312 towards the mounting plate 2 to overcome the supporting force of the first elastic element 313, forcing the locking block 312 to rotate around the middle section pivot, and the upper end will simultaneously disengage from the locking groove 311, releasing the single-point lock; after pressing all the locking blocks 312 in sequence, the distribution box 1 and the mounting plate 2 are completely unlocked, and the distribution box 1 can be quickly removed along the sliding direction. After maintenance is completed, slide the distribution box 1 along the mounting plate 2 to the preset position and release the pressed lower end of the locking block 312. Under the action of elastic restoring force, the first elastic element 313 pushes the lower end of the locking block 312 to reset (away from the mounting plate), thereby causing the upper end of the locking block 312 to automatically spring into the corresponding slot 311, completing the elastic locking of all points, without the need for additional manual calibration, and quickly restoring the cooling water distribution function.

[0037] Furthermore, the first elastic element 313 is preferably a steel spring.

[0038] In some embodiments, such as Figure 1 , Figure 3 As shown, the connecting part 3 also includes a linkage 32. The linkage 32 includes a rotating shaft 321 rotatably disposed at the lower end of each locking block 312. A connecting rope 322 is fixedly connected between two adjacent rotating shafts 321. A pull rope 323 is fixedly connected to the rotating shaft 321 located at the lowest side. When the two pull ropes 323 on both sides are pulled downwards, the pull ropes 323 drive the lower end of the locking block 312 to move closer to the mounting plate 2 via the rotating shaft 321. At the same time, the rotating shaft 321 drives other locking blocks 312 to move closer to the mounting plate 2 via the connecting rope 322, so that multiple locking blocks 312 are unlocked simultaneously.

[0039] The turbine cooling water distribution device in this invention, which facilitates maintenance, utilizes a pull-rope linkage design. This eliminates the need for operators to individually locate and align the lower end of each locking block; only the exposed pull rope applies force. This design is suitable for scenarios with limited space and a narrow field of vision in the distribution box, reducing operational difficulty and making it particularly suitable for rapid emergency maintenance. All locking blocks are subjected to force, rotate, and disengage synchronously, preventing hard friction and jamming between the locking slots and blocks caused by excessively fast or slow unlocking of individual blocks, or deformation caused by uneven force on the distribution box. This protects the structural integrity of the locking blocks, slots, and linkage components, extending the device's service life.

[0040] Specifically, when the distribution box 1 needs maintenance, the operator pulls the two pull ropes 323 on the left and right sides downwards (corresponding to the linkages 32 on the left and right sides). The pull ropes 323 drive the lowest rotating shaft 321 connected to them to rotate downwards. This rotating shaft 321 pulls the adjacent rotating shaft 321 above it to rotate synchronously through the connecting rope 322. When all rotating shafts 321 rotate, they synchronously drive the lower end of the locking block 312 connected to them to move towards the mounting plate 2 (overcoming the supporting force of the first elastic element 313). According to the lever principle, the locking block 312 rotates around the central pivot point, and the upper end of all locking blocks 312 synchronously disengages from the locking slot 311, completely unlocking the distribution box 1 from the mounting plate 2.

[0041] In some embodiments, a handle is fixedly connected to the lower end of the pull rope 323, and the handle is provided with an anti-slip groove. The handle is used to facilitate the operator to pull the pull rope 323.

[0042] The turbine cooling water distribution device in this embodiment of the invention, which facilitates maintenance, provides a clear force-applying carrier for the pull rope through a handle, eliminating the need for operators to directly pull the thin rope and increasing the contact area for force application. Simultaneously, the handle's ergonomic design makes the downward pulling action smoother, allowing for easy force application even in confined spaces and reducing operational intensity. The anti-slip grooves on the handle surface effectively increase the static friction between the hand and the handle, preventing slippage due to sweaty, oily hands or limited space during pulling. Especially in turbine operating environments where oil and moisture may be present, the anti-slip design ensures the stability of the unlocking operation, preventing component damage or personnel injury due to operational errors.

[0043] Specifically, when the distribution box 1 needs maintenance, the operator holds the handle at the lower end of the pull rope 323 (the anti-slip groove increases the friction between the hand and the handle to prevent slippage) and pulls the handles on both sides downwards simultaneously. The handle drives the lowest rotating shaft 321 downwards via the pull rope 323. This rotating shaft 321 pulls the adjacent rotating shaft 321 above it to rotate synchronously via the connecting rope 322, thereby driving all rotating shafts 321 to rotate in tandem.

[0044] In some embodiments, such as Figure 1 , Figure 4 As shown, the dispensing box 1 and the mounting plate 2 are slidably connected by a sliding part 4, which includes multiple limiting plates 41 and multiple movable sleeves 42.

[0045] Multiple limiting plates 41 are fixedly connected to the left and right sides of the mounting plate 2 respectively. The limiting plates 41 are used to limit the sliding trajectory of the dispensing box 1. Multiple movable card sleeves 42 are fixedly connected to the left and right sides of the distribution box 1, and the multiple movable card sleeves 42 correspond one-to-one with multiple limiting card plates 41. The movable card sleeves 42 are slidably connected in the limiting card plates 41.

[0046] The turbine cooling water distribution device in this embodiment of the invention, which facilitates maintenance, prevents the distribution box 1 from shifting or jamming during sliding by setting a sliding part, ensuring precise alignment between the locking block and the locking slot, and improving assembly and disassembly efficiency. The cooperation between the limiting plate and the moving sleeve distributes the weight and operating load of the distribution box 1, reduces the stress on the connecting parts, and limits lateral sway, thereby improving installation stability.

[0047] Specifically, the limiting plates 41 fixed on the left and right sides of the mounting plate 2 correspond one-to-one with the movable sleeves 42 fixed on the left and right sides of the distribution box 1. The movable sleeves 42 are fitted onto the limiting plates 41 to form a sliding fit. When the distribution box 1 needs to be installed or removed, it slides along the extension direction (up and down direction) of the limiting plates 41. The limiting plates 41 restrict the offset of the movable sleeves 42, ensuring that the distribution box 1 slides smoothly along the preset trajectory. When it slides to the target position, the locking block 312 and the locking slot 311 precisely align to complete the locking; after unlocking, the distribution box 1 can be removed by sliding along the limiting plates 41.

[0048] Furthermore, two limiting plates 41 are symmetrically arranged on the left and right sides of the mounting plate 2. Two movable sleeves 42 are symmetrically arranged on the left and right sides of the dispensing box 1.

[0049] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the connector 31 also includes a protective shell 314, which is disposed on the movable card sleeve 42. The card block 312 is rotatably connected in the protective shell 314. The protective shell 314 is used to protect the card block 312 and prevent accidental contact.

[0050] The turbine cooling water distribution device in this embodiment of the invention, which facilitates maintenance, prevents accidental unlocking of the locking block 312 due to accidental contact by personnel during turbine operation or maintenance by the protective shell. It also prevents dust, moisture, and oil from entering the locking block 312, ensuring locking reliability. The protective shell also protects the locking block 312 and rotating connections, reducing collisions and wear, and extending the service life of the components.

[0051] Specifically, the protective shell 314 is fixed to the movable card sleeve 42, and the middle section of the card block 312 is rotatably connected to the inside of the protective shell 314, with its upper end extending out of the protective shell 314 to engage with the card slot 311. The card block 312 rotates within the protective shell 314, and its upper end is embedded in the card slot 311 to achieve locking; when the lower end of the card block 312 is driven by the linkage structure, the card block 312 rotates within the shell to complete unlocking, and the protective shell 314 does not interfere with the core operation. The protective shell 314 encloses the main body of the card block 312, exposing only the necessary operating parts to avoid accidental external contact or contact with foreign objects.

[0052] In some embodiments, such as Figure 1 , Figure 5As shown, an auxiliary part 5 is provided between the bottom of the distribution box 1 and the mounting plate 2. The auxiliary part 5 includes a support plate 51, an auxiliary plate 52, and a second elastic member 53.

[0053] Support plate 51 is located on the lower side of mounting plate 2; The auxiliary plate 52 is located between the support plate 51 and the mounting plate 2; The second elastic element 53 is located between the support plate 51 and the auxiliary plate 52. The second elastic element 53 is used to apply a downward force to the distribution box 1 through the support plate 51 so as to facilitate the separation of the distribution box 1 from the mounting plate 2.

[0054] The turbine cooling water distribution device in this embodiment of the invention, which facilitates maintenance, reduces the resistance to contact between the distribution box and the mounting plate after unlocking by setting up auxiliary parts, eliminating the need for additional pulling force. It is especially suitable for heavier distribution boxes, further improving the ease of operation in confined spaces. The elastic pushing mechanism prevents the distribution box from getting stuck due to long-term installation, vibration, or slight deformation, ensuring smooth disassembly and removal.

[0055] Specifically, the support plate 51 is located below the mounting plate 2, and the auxiliary plate 52 is positioned between the support plate 51 and the mounting plate 2. The second elastic element 53 connects the two and is in a pre-compressed state. After the distribution box 1 is unlocked, the second elastic element 53 releases its elastic force, pushing the auxiliary plate 52 upward to push the mounting plate 2 (or directly pushing the bottom of the distribution box 1), indirectly applying a downward separation force to the distribution box 1. This downward force assists the distribution box 1 in quickly separating from the mounting plate 2 along the sliding part 4, making it easy for the operator to remove.

[0056] In some embodiments, such as Figure 5 As shown, the auxiliary part 5 also includes a limiting post 54 disposed on the support plate 51. The auxiliary plate 52 is slidably sleeved on the limiting post 54, and the limiting post 54 is used to install the support plate 51.

[0057] The turbine cooling water distribution device in this embodiment of the invention, which is easy to maintain, uses a limiting column to constrain the movement direction of the auxiliary plate, preventing it from shifting or tilting during elastic pushing and ensuring stable assist effect.

[0058] Specifically, the limiting post 54 is fixed to the support plate 51, the auxiliary plate 52 is slidably sleeved on the limiting post 54, and the second elastic element 53 is sleeved or connected between the support plate 51 and the auxiliary plate 52 (along the axis of the limiting post 54). The limiting post 54 also serves to position and install the support plate 51. After the distribution box 1 is unlocked, the second elastic element 53 releases its elastic force, pushing the auxiliary plate 52 upward along the axis of the limiting post 54, pushing the bottom of the distribution box 1, and applying a downward separation force. The limiting post 54 restricts the sliding trajectory of the auxiliary plate 52, preventing deviation and ensuring that the elastic force is accurately applied to the distribution box 1, assisting it in disengaging from the mounting plate 2 along the sliding part 4.

[0059] In some embodiments, such as Figure 6 As shown, a handle 6 is fixedly connected to the top of the dispensing box 1. The handle 6 is used by the operator to pull the dispensing box 1.

[0060] The turbine cooling water distribution device in this embodiment of the invention provides a clear gripping point through the handle, avoiding the need to fumble for the force application position of the distribution box in a narrow space, and is suitable for quick assembly and disassembly.

[0061] Specifically, the dispensing box 1 is unlocked via a linkage mechanism, and after the auxiliary part 5 provides separation assistance, the operator holds the handle 6 and pulls it downwards (or along the trajectory of the sliding part 4) to disengage the dispensing box 1 from the mounting plate 2. After maintenance is completed, the operator holds the handle 6 and slides the dispensing box 1 upwards along the sliding part 4 to the target position to complete the locking mechanism.
