Description

Technical Field

[0001] This application relates to the technical field of turbine generator gate installation, and in particular to a gate installation structure for a full-flow turbine generator. Background Technology

[0002] A full-flow hydro generator is a power generation device that uses water flow to generate electricity. The generator rotor has an internal shaft, and the mixed-flow turbine and external stator are integrated into one unit.

[0003] Currently, the relevant technology for installing gates for full-flow turbine generators, such as the Chinese patent "A Gate Installation Structure for Full-Flow Turbine Generators" with authorization announcement number CN213899158U, discloses a gate installation structure for a full-flow turbine generator, including a turbine generator and a gate. The turbine generator is located within the gate's interlayer. One end of the turbine generator is fixed to the outlet end of the gate by several No. 1 bolts and spring washers. The other end of the turbine generator has several circumferentially distributed bosses on its side wall. The inlet end of the gate is supported by several No. 2 bolts against the bosses of the turbine generator, and the No. 2 bolts are fitted with fixing nuts for tightening. This installation structure reduces the amount of civil engineering excavation required for traditional generator installations, saving on the overall project cost.

[0004] The aforementioned technologies have the following shortcomings: when fixing the hydro-generator and the gate, a large number of bolts are required to secure them, resulting in cumbersome installation and low installation efficiency. Summary of the Invention

[0005] To improve the installation efficiency of the turbine generator and gate, this application provides a full-flow turbine generator gate installation structure.

[0006] The technical solution for the gate installation structure of a full-flow turbine generator provided in this application is as follows:

[0007] A gate installation structure for a full-flow turbine generator includes a turbine generator and a gate, wherein the turbine generator is installed inside the gate, and both ends of the turbine generator are fixed with fixing components for fixing the turbine generator and the gate. The fixing components include a plug rod inserted towards the turbine generator, the plug rod being slidably installed inside the gate, and the turbine generator having a circumferential opening for the plug rod to be inserted into. The end of the plug rod away from the insertion hole is provided with a support component for pressing the plug rod against the insertion hole.

[0008] By adopting the above technical solution, after the hydro-generator is installed on the gate, the plug rod slides towards the hydro-generator under the action of the support component, so that the plug rod is inserted into the plug hole, thereby achieving the effect of fixing the hydro-generator inside the gate. The support component supports the plug rod to ensure the stability of the plug connection between the plug rod and the plug hole. The hydro-generator and the gate can be fixedly installed without the need for installation bolts, thereby improving the installation efficiency of the hydro-generator and the gate.

[0009] Optionally, the hydro-generator has multiple circumferential holes, one hole corresponding to one rod, and the multiple rods can slide towards or away from the hydro-generator.

[0010] By adopting the above technical solution, multiple plug rods and plug holes are interlocked, further enhancing the connection stability between the gate and the hydro-generator.

[0011] Optionally, the gate is further equipped with a limiting component to restrict the sliding direction of the insertion rod. The limiting component includes a fixing block with a through hole for the insertion rod to slide through. The limiting component also includes a limiting block fixed to the side wall of the insertion rod. The fixing block has a limiting groove that communicates with the through hole. The length direction of the limiting groove is perpendicular to the axial direction of the hydro-generator. The limiting block is slidably connected to the limiting groove. A limiting spring is also fixed inside the limiting groove. One end of the limiting spring is fixedly connected to the limiting block, and the other end of the limiting spring is fixedly connected to the inside of the limiting groove.

[0012] By adopting the above technical solution, the limiting component can limit the insertion rod in different positions. The through hole restricts the sliding direction of the insertion rod. The limiting block and the limiting groove reduce the insertion rod from leaving the through hole. The limiting spring keeps the insertion rod in a position away from the insertion hole, ensuring that the hydro-generator can slide normally into the gate before being fixed by the insertion rod.

[0013] Optionally, the support assembly is installed inside the gate. The support assembly includes an annular inflatable sealing ring. The fixing block is also provided with a receiving groove for accommodating the inflatable sealing ring. The receiving groove communicates with the through hole. The inner circumference of the inflatable sealing ring abuts against the insertion rod, and the outer circumference of the inflatable sealing ring abuts against the side wall of the receiving groove.

[0014] By adopting the above technical solution, after the hydro-generator slides into the gate, the air inlet of the air-filled sealing ring is inflated, causing the air-filled sealing ring to bulge. The air-filled sealing ring then pushes the insertion rod to slide towards the side closer to the insertion hole, thus achieving insertion and fixation. This saves manpower. At the same time, the air-filled sealing ring can further enhance the sealing between the gate and the hydro-generator, reducing the possibility of water entering the gate interlayer during actual application of the hydro-generator.

[0015] Optionally, the support assembly further includes a support frame installed inside the inflatable sealing ring. The support frame is arranged opposite to the insertion rod. The support frame includes an elastic arc-shaped plate. One end of the arc-shaped plate is fixedly connected to one side of the inner peripheral wall of the inflatable sealing ring, and the other end is fixedly connected to one side of the outer peripheral wall of the inflatable sealing ring. Both ends of the arc-shaped plate are fixed with elastic plates, and the ends of the two elastic plates away from the arc-shaped plate are fixed to each other.

[0016] By adopting the above technical solution, the support frame can further enhance the support effect of the inflatable sealing ring on the insertion rod by utilizing the elastic support of the arc plate and the elastic plate, thereby improving the fixing effect of the fixing component. In addition, the support frame can reduce the damage to the inflatable sealing ring caused by the insertion rod. The support frame supports the inflatable sealing ring from the inside, which can effectively extend the service life of the inflatable sealing ring.

[0017] Optionally, a sliding rod is fixedly connected to the middle section of the arc-shaped plate. The sliding rod extends towards the side close to the elastic plate. A sleeve for inserting the sliding rod is fixed between the two elastic plates. A support spring is also sleeved on the sliding rod. One end of the support spring is fixed to the end face of the sleeve, and the other end is fixedly connected to the arc-shaped plate.

[0018] By adopting the above technical solution, when the two ends of the arc plate are far apart, the arc plate supports the inflatable sealing ring. The sliding rod and sleeve further enhance the support effect. The sliding rod is slidably installed in the sleeve, and under the action of the support spring, the sliding rod and sleeve move closer to each other, thereby enhancing the support effect of the arc plate on the inflatable sealing ring.

[0019] Optionally, a magnet is fixed to one end of the arc-shaped plate near the insertion rod, and the insertion rod is made of ferrous metal, with the insertion rod and the magnet attracting and fixing each other.

[0020] By adopting the above technical solution, during the inflation process of the inflatable sealing ring, the magnet and the insert rod automatically attract and fix each other, enabling the support frame to automatically align with the insert rod and enhancing the stability of the support.

[0021] Optionally, the gate is slidably connected to the hydro-generator, a base is installed at the bottom of the hydro-generator, and a track for the base to slide is fixedly installed on the inner bottom wall of the gate.

[0022] By adopting the above technical solution, the hydro-generator slides through the base and the track, which facilitates the quick installation of the hydro-generator into the gate and improves installation efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Under the action of the support component, the insertion rod slides towards the direction of the hydro-generator, so that the insertion rod is inserted into the insertion hole, thereby achieving the effect of quickly fixing the hydro-generator inside the gate. The support component supports the insertion rod to ensure the stability of the insertion between the insertion rod and the insertion hole. The hydro-generator and the gate can be fixedly installed without the need for installation bolts, thereby improving the installation efficiency of the hydro-generator and the gate.

[0025] 2. The limiting component can limit the insertion rod in different positions. The through hole restricts the sliding direction of the insertion rod. The limiting block and the limiting groove reduce the insertion rod from disengaging from the through hole. The limiting spring keeps the insertion rod in a position away from the insertion hole, ensuring that the hydro-generator can slide normally into the gate before being fixed by the insertion rod.

[0026] 3. During the inflation process of the air-sealing ring, the magnet and the insert rod automatically attract and fix each other, so that the support frame can automatically align with the insert rod, enhancing the stability of the support. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a gate installation structure for a full-flow turbine generator.

[0035] Reference Figure 1 and Figure 2 The full-flow turbine generator gate installation structure includes a turbine generator 1 and a gate 2. The gate 2 is a symmetrical frame structure. The turbine generator 1 is slidably connected to the gate 2, and the turbine generator 1 can be slidably installed inside the gate 2. Two parallel rails 21 are fixed to the inner bottom wall of the gate 2, and two parallel bases 11 are fixed to the bottom of the turbine generator 1. The bases 11 are horizontally inserted into the rails 21. A fixing component 3 and a support component 4 are provided between the turbine generator 1 and the gate 2 to fix them together. The support component 4 is located on the side of the fixing component 3 away from the turbine generator 1. When installing the turbine generator 1, the bases 11 slide into the rails 21, so that the stator and rotor of the turbine generator 1 are located in the interlayer of the gate 2, and the turbine generator 1 is fixed inside the gate 2 by the fixing component 3. The support component 4 drives the fixing component 3 to automatically fix the turbine generator 1, thereby improving the installation efficiency of the turbine generator 1.

[0036] Reference Figure 1 One end of the turbine generator 1 is the inlet end 12, and the other end is the outlet end 13. There are two fixing components 3, which are located at the inlet end 12 and the outlet end 13 of the turbine generator 1, respectively. Each fixing component 3 is supported and fixed on the side away from the turbine generator 1 by a support component 4 to ensure the connection stability between the turbine generator 1 and the gate 2.

[0037] Reference Figure 1 and Figure 3 The fixing component 3 includes a fixing ring 31 fixed to the outer circumferential wall of the turbine generator 1. The axis of the fixing ring 31 is collinear with the axis of the turbine generator 1. The fixing ring 31 has multiple insertion holes 311, four in this embodiment, which are symmetrically arranged about the fixing ring 31. The fixing component 3 also includes multiple insertion rods 32 slidably installed inside the gate 2. The multiple insertion rods 32 are arranged one-to-one with the insertion holes 311, and the insertion rods 32 can be inserted into the insertion holes 311. When the turbine generator 1 is slid horizontally into the gate 2, the insertion rods 32 are located on the side away from the insertion holes 311. After the turbine generator 1 is inside the gate 2, the insertion rods 32 slide toward the insertion holes 311 and insert into the insertion holes 311, thereby achieving a fixed connection between the turbine generator 1 and the gate 2.

[0038] A limiting component 5 is installed inside the gate 2. The limiting component 5 restricts the sliding direction of the insertion rod 32, allowing the insertion rod 32 to be accurately inserted into the insertion hole 311. The limiting component 5 includes an annular fixing block 51 fixedly installed inside the gate 2. The axis of the fixing block 51 is on the same straight line as the axis of the fixing ring 31. The fixing block 51 is located on the side of the fixing ring 31 away from the turbine generator 1. Multiple through holes 511 are opened on the side of the fixing block 51 closest to the fixing ring 31. The through holes 511 are opposite to the insertion holes 311 one by one, and the insertion rod 32 is slidably installed in the through holes 511.

[0039] The fixing block 51 is also provided with a plurality of limiting grooves 512, the number of limiting grooves 512 being the same as the number of through holes 511, and the limiting grooves 512 communicating with the through holes 511. The length direction of the limiting grooves 512 is parallel to the length direction of the insertion rod 32. The limiting assembly 5 also includes a limiting block 52 that slides along the length direction of the limiting groove 512. The limiting block 52 is fixedly connected to the side wall of the insertion rod 32. A limiting spring 53 is also fixedly connected inside the limiting groove 512. One end of the limiting spring 53 is fixedly connected to the limiting block 52. The other end of 53 is fixedly connected to the side wall of the limiting groove 512 away from the insertion hole 311. The limiting spring 53 gives the limiting block 52 a force to retract into the limiting groove 512, making it difficult for the insertion rod 32 to disengage from the through hole 511, and at the same time keeping the insertion rod 32 in a position away from the insertion hole 311, ensuring that the hydro-generator 1 can slide horizontally into the gate 2. When the insertion rod 32 is inserted into the insertion hole 311 under the action of the support component 4, the limiting spring 53 is stretched, and the limiting block 52 slides in the limiting groove 512 toward the direction of the insertion hole 311.

[0040] The support assembly 4 includes an annular inflatable sealing ring 41. The fixing block 51 also has an annular receiving groove 513, which is connected to the through hole 511. The inflatable sealing ring 41 is located within the receiving groove 513 and is positioned on the side of the insertion rod 32 away from the insertion hole 311. The inflatable sealing ring 41 has an openable and closable inflation port (not shown in the figure). The inflatable sealing ring 41 is made of rubber. Gas is injected into the inflation port using an inflation device, causing the inflatable sealing ring 41 to inflate. When the inflatable sealing ring 41 inflates, its inner circumference abuts against the insertion rod 32. The periphery abuts against the side wall of the receiving groove 513. An inflatable sealing ring 41 can simultaneously push multiple insertion rods 32 toward the direction of the insertion hole 311, realizing the insertion and fixing of the insertion rods 32 and the insertion hole 311. This can save manpower to quickly install and fix the water turbine generator 1 and the gate 2. In addition, the inflatable sealing ring 41 can further enhance the sealing of the water inlet end 12, reduce the situation of water seeping inward along the gap between the gate 2 and the water turbine generator 1, which is conducive to extending the service life of the internal components of the water turbine generator 1 and reducing the situation of water entering and corroding the internal components of the water turbine generator 1.

[0041] Reference Figure 3 and Figure 4 Multiple support frames 42 are also installed inside the inflatable sealing ring 41. The number of support frames 42 is the same as the number of insertion rods 32, and the support frames 42 are arranged opposite to the insertion rods 32. The support frames 42 provide further support to the insertion rods 32 from inside the inflatable sealing ring 41, so that the insertion rods 32 can be inserted into the insertion holes 311 more stably. At the same time, the support frames 42 can reduce the damage to the inflatable sealing ring 41 and extend the service life of the inflatable sealing ring 41.

[0042] Reference Figure 4 and Figure 5 The support frame 42 includes an arc-shaped plate 421, which is made of elastic material. When the arc-shaped plate 421 is compressed, its two ends move closer to each other. One end of the arc-shaped plate 421 abuts against the inner wall of the inflatable sealing ring 41 near the insertion rod 32, and the other end of the arc-shaped plate 421 abuts against the inner wall of the inflatable sealing ring 41 away from the insertion rod 32. Elastic plates 422 are fixed to both ends of the arc-shaped plate 421, with the ends of the elastic plates 422 away from the arc-shaped plate 421 fixed to each other. The elastic plates 422 are made of elastic material. A sleeve 423 and a sliding rod 4 are provided between the two elastic plates 422 and the arc-shaped plate 421. 24. One end of the slide rod 424 is fixedly connected to the middle section of the arc plate 421, and the other end of the slide rod 424 extends toward the side close to the elastic plate 422. The sleeve 423 is fixed between the two elastic plates 422 and extends toward the side close to the arc plate 421. The slide rod 424 is inserted into the sleeve 423, and the slide rod 424 can slide along the length direction of the sleeve 423. A support spring 425 is also fixed on the side wall of the sleeve 423 near the slide rod 424. The support spring 425 is sleeved on the outside of the slide rod 424, and the end of the support spring 425 away from the sleeve 423 is fixedly connected to the arc plate 421.

[0043] To ensure that the support frame 42 can accurately support the insertion rod 32, a magnet block 426 is fixed to one end of the arc plate 421 near the insertion rod 32. The magnet block 426 is fixed to the inner wall of the inflatable sealing ring 41. The insertion rod 32 is made of iron metal. When the inflatable sealing ring 41 is inflated, the insertion rod 32 and the magnet block 426 can be accurately positioned and attracted to each other, which further enhances the support effect of the inflatable sealing ring 41 on the insertion rod 32 and enhances the insertion stability of the insertion rod 32 and the insertion hole 311.

[0044] The implementation principle of the full-flow turbine generator gate installation structure in this application embodiment is as follows: When the turbine generator 1 needs to be installed inside the gate 2, the base 11 is aligned with the track 21. After the turbine generator 1 is horizontally slid to the gate 2, the air-filled sealing ring 41 is inflated, causing the air-filled sealing ring 41 to bulge. After the air-filled sealing ring 41 is fully inflated, the inflation port is closed to keep the pressure inside the air-filled sealing ring 41 stable. The bulging of the air-filled sealing ring 41 pushes the insertion rod 32 to slide toward the insertion hole 311. Finally, the insertion hole 311 and the insertion rod 32 are inserted and fixed, so that the turbine generator 1 is quickly installed inside the gate 2. While the air-filled sealing ring 41 plays a supporting and fixing role, it further enhances the sealing between the gate 2 and the turbine generator 1, reduces the situation of water seeping in along the gap between the two, and thus extends the service life of the turbine generator 1.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
