Description

Technical Field

[0001] This utility model relates to the field of pipeline clamp technology, specifically a cooling water pipeline clamp for a gas turbine power plant. Background Technology

[0002] In the operating system of a gas turbine power plant, the cooling water pipeline is a key component ensuring the safe and stable operation of the unit. It is responsible for timely dissipating the heat generated by core equipment such as the gas turbine and generator during operation, maintaining the equipment within a reasonable operating temperature range. The cooling water pipeline in a gas turbine power plant is typically composed of multiple sections of metal pipe connected by flanges, welding, and other methods. The cooling water transported inside the pipeline has a certain pressure and flow rate, and is subject to continuous stress and displacement due to factors such as vibration and temperature changes during unit operation.

[0003] However, existing cooling water pipe clamps have poor versatility, with their dimensions mostly being fixed specifications that can only accommodate pipes of specific diameters. This design necessitates gas turbine power plants to stock a large number of spare clamps of different specifications, which not only occupies a significant amount of storage space but also increases the complexity of spare parts management. Furthermore, when actually replacing or installing clamps, operators must first accurately measure the pipe diameter and then select a matching clamp from a large number of spare parts. This process is time-consuming and labor-intensive, especially in emergency repair scenarios, where incompatible clamp specifications may delay the project and reduce the recovery efficiency of the cooling system. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water pipeline clamp for gas turbine power plants to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A cooling water pipe clamp for a gas turbine power plant includes a connecting base, a connecting plate mounted on the top of the connecting base, a fixed plate installed inside the connecting plate, a regular hexagonal groove formed on the side of the fixed plate, a swivel ring suspended inside the connecting plate, the swivel ring being rotatably connected to the fixed plate, a driving plate installed inside the swivel ring, six sets of driving grooves evenly spaced on the side of the driving plate, six sets of clamping blocks arranged between the fixed plate and the driving plate, the six sets of clamping blocks forming a ring, adjacent clamping blocks fitting together, a slider mounted on one side of each clamping block, the slider sliding within the groove. A driving block is installed on the other side of the clamping block. The driving block slides in the driving groove. The connecting plate, the fixing plate, and the driving plate all have coaxial cavities. A driving component is installed on the outside of the connecting plate. The driving component drives the driving plate to rotate. When the driving component drives the driving plate to rotate, the driving block slides along the driving groove, causing the clamping block to move synchronously in the regular hexagonal sliding groove through the slider. The six sets of clamping blocks are always in contact to form a ring structure with a variable diameter, which can be adapted to cooling water pipes with different outer diameters. There is no need to store multiple specifications of clamps, reducing storage costs and operational complexity. The close contact of adjacent clamping blocks prevents pipe shaking and improves fixation stability.

[0007] Furthermore, the driving component includes a connecting frame mounted on the outside of the connecting plate. A knob is provided on the side of the connecting frame, and a worm gear is coaxially connected to the knob. A rotating shaft is also mounted on the outside of the connecting plate via a bearing seat. A worm wheel is coaxially mounted on the outside of the rotating shaft. The worm gear and the worm wheel are meshed together. A driving gear is coaxially connected to the outside of the rotating shaft, and a driven gear is coaxially connected to the outside of the rotating ring. The driving gear and the driven gear are meshed together. The worm gear and worm wheel transmission has self-locking properties, which can prevent the clamping block from loosening due to pipeline vibration and ensure reliable fixation. The gear meshing amplifies the torque, and the operator can easily drive the clamping block to move by turning the knob, reducing the operation intensity and making it suitable for the frequent adjustment needs of power plant sites.

[0008] Furthermore, the radius of the driving gear is smaller than that of the driven gear. The small gear drives the large gear to achieve speed reduction and torque increase. A small rotation of the knob can make the clamping block produce sufficient displacement, improving the adjustment accuracy. At the same time, it reduces the driving force required, making it easier to accurately control the clamping force and avoid over-clamping and damaging the pipeline.

[0009] Furthermore, the connecting disc has an opening on its side, and the meshing point of the driving gear and the driven gear is located inside the opening. The opening provides space for gear meshing, ensuring precise meshing between the driving gear and the driven gear, and preventing the connecting disc housing from obstructing transmission; at the same time, it facilitates observation of gear wear and makes maintenance convenient.

[0010] Furthermore, a protective cover is installed on the outside of the connecting plate by screws. The worm, worm wheel, drive gear, and rotating shaft are all located inside the protective cover. The protective cover isolates dust, water vapor, and corrosive media in the power plant environment, preventing the transmission components from rusting or jamming and extending their service life. At the same time, it prevents operators from contacting the rotating parts, improving safety.

[0011] Furthermore, the orthographic projection of the clamping block is an isosceles triangle. The isosceles triangle structure makes the clamping block contact surface inclined, resulting in a large contact area between adjacent clamping blocks. The triangular structure is rigid and can withstand the radial force generated by pipeline vibration, thus preventing the clamping block from deforming.

[0012] Furthermore, the fixed plate has a groove on its side, and a connecting ring is installed on the inner side of the rotating ring. The connecting ring rotates in the groove, and the connecting ring cooperates with the groove to axially limit the rotating ring, preventing it from shifting axially during rotation, ensuring that the drive plate and the fixed plate are parallel, and thus ensuring that the clamping block moves synchronously; the sliding friction is small, making the rotating ring rotate more smoothly.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the driving component drives the driving disc to rotate, the driving block slides along the driving groove, causing the clamping block to move synchronously in the regular hexagonal sliding groove through the slider. The six sets of clamping blocks are always in contact to form a ring structure with a variable diameter, which can be adapted to cooling water pipes with different outer diameters. There is no need to store multiple specifications of clamps, reducing storage costs and operational complexity. The close contact of adjacent clamping blocks prevents pipe shaking and improves fixing stability. Attached Figure Description

[0023] Example 1

[0024] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a cooling water pipe clamp for a gas turbine power plant, including a connecting seat 1, a connecting plate 2 installed at the top of the connecting seat 1, a fixing plate 14 installed inside the connecting plate 2, a regular hexagonal groove 15 opened on the side of the fixing plate 14, a rotating ring 3 suspended inside the connecting plate 2, the rotating ring 3 and the fixing plate 14 being rotatably connected, a driving plate 4 installed inside the rotating ring 3, six sets of driving grooves 9 evenly spaced on the side of the driving plate 4, six sets of clamping blocks 11 between the fixing plate 14 and the driving plate 4, the six sets of clamping blocks 11 forming a ring, adjacent clamping blocks 11 fitting together, and a slider 17 installed on one side of the clamping block 11. The slider 17 slides in the slide groove 15. A drive block 12 is installed on the other side of the clamping block 11. The drive block 12 slides in the drive groove 9. The connecting plate 2, the fixed plate 14, and the drive plate 4 are all provided with coaxial cavities 16. A drive component is installed on the outside of the connecting plate 2. The drive component drives the drive plate 4 to rotate. After the cooling water pipe passes through the cavity 16, the drive component drives the drive plate 4 to rotate. The drive groove 9 applies radial force through the drive block 12, causing the clamping block 11 to retract towards the center or open outward along the slide groove 15. When retracted, the clamping block 11 adheres to the outer wall of the pipe to achieve fixation. When opened, the pipe can be removed. The guide of the slide groove 15 ensures that the movement of the clamping block 11 is synchronous and ensures the concentricity of the clamping.

[0025] As an embodiment of this utility model, the driving component further includes a connecting frame 6 installed on the outside of the connecting plate 2. A knob 7 is provided on the side of the connecting frame 6. A worm gear 13 is coaxially connected to the knob 7. A rotating shaft 20 is also installed on the outside of the connecting plate 2 through a bearing seat. A worm wheel 8 is coaxially installed on the outside of the rotating shaft 20. The worm gear 13 and the worm wheel 8 are meshed together. A driving gear 5 is coaxially connected to the outside of the rotating shaft 20. A driven gear 10 is coaxially connected to the outside of the rotating ring 3. The driving gear 5 and the driven gear 10 are meshed together. Rotating the knob 7 drives the worm gear 13 to rotate. The worm gear 13 meshes with the worm wheel 8 to make the rotating shaft 20 rotate. The driving gear 5 drives the driven gear 10 and the rotating ring 3 to rotate, thereby making the driving plate 4 rotate synchronously. The rotational motion of the knob is converted into the radial movement of the clamping block 11 through mechanical transmission.

[0026] As an embodiment of this utility model, the radius of the driving gear 5 is smaller than the radius of the driven gear 10. The tooth ratio between the driving gear 5 and the driven gear 10 makes the rotation speed of the rotating ring 3 lower than that of the rotating shaft 20, thereby making the clamping block 11 move slowly, which makes it easier for the operator to accurately adjust the clamping range according to the pipe diameter.

[0027] As an embodiment of this utility model, the side of the connecting disk 2 is further provided with an opening, and the meshing part of the driving gear 5 and the driven gear 10 is located in the opening. The driving gear 5 extends into the interior of the connecting disk 2 through the opening and meshes with the driven gear 10, ensuring that the power is stably transmitted from the external driving component to the rotating ring 3. The size of the opening is adapted to the diameter of the gear to avoid motion interference.

[0028] As an embodiment of this utility model, a protective cover is further installed on the outside of the connecting plate 2 by screws. The worm 13, worm wheel 8, drive gear 5, and rotating shaft 20 are all located inside the protective cover. The protective cover is fixed to the outside of the connecting plate 2 by screws, sealing the exposed transmission components and exposing only the knob 7 for operation. Its sealing structure prevents contaminants from entering and ensures the long-term stable operation of components such as the worm 13 and gear.

[0029] As an embodiment of this utility model, the orthographic projection of the clamping block 11 is an isosceles triangle.

[0030] As an embodiment of this utility model, the fixed disk 14 is further provided with a groove 18 on its side, and a connecting ring 19 is installed on the inner side of the rotating ring 3. The connecting ring 19 rotates in the groove 18. When the rotating ring 3 rotates, the connecting ring 19 slides along the groove 18. The side wall of the groove 18 restricts the radial sway of the rotating ring 3, ensuring that the drive groove 9 of the drive disk 4 and the drive block 12 of the clamping block 11 are always precisely matched, avoiding transmission jamming.
