Description

Technical Field

[0001] The invention relates to the technical field of pumped storage power generation motor sets, in particular to a multi-parameter matrix cluster universal combination self-locking support module. Background Art

[0002] Compared with traditional hydro-turbine generator sets, pumped storage units have more complex operating conditions, with two completely different operating conditions: pumping and power generation. They have a large number of electromagnetic branches, which means that the pumped storage units have a large number of energy leads and many layers, requiring more support and locking.

[0003] Traditional designs use individually designed grooved and non-grooved spacers, brackets, and other components to support and lock the energy leads of different units, depending on their cross-sectional dimensions. This has long presented the following problems: 1. A one-unit, one-model design results in excessively high product costs. Due to the high energy density and current intensity transmitted within the energy leads, components in contact with them must be made of insulating materials. Manufacturing large quantities of insulating materials requires mold production. Traditional designs fail to consider interoperability, often requiring a single mold per unit, which is not universal. This results in extremely high production costs and significant mold waste. 2. The storage and use of spare parts are expensive. With the widespread deployment of pumped-storage units, power companies often establish dispatching centers and spare parts centers at distribution centers for multiple pumped-storage units, allowing for shared use across multiple power stations within a region to improve efficiency. However, the traditional one-unit, one-model design prevents interoperability between units, requiring a customized design based on the number of units, resulting in significant operational and maintenance costs. 3. Traditional structural designs also have drawbacks. Due to its own design limitations, the traditional structure will take up a lot of space after the ring plate is laid on the stator frame, and may even fill up the entire space, making the already narrow inspection and maintenance space even more difficult to enter and operate, posing a safety hazard to operation and maintenance.

[0004] The typical traditional structure consists of a bracket, a non-grooved spacer, a grooved spacer, a fixing screw, and a fixing nut. It suffers from the following characteristics: 1. It lacks overall height adjustment capability. The bracket must be cut and adjusted on-site to adjust the overall height before being welded to the stator base ring plate. This welding process eliminates height adjustment capability, making it impossible to adjust the height of any component. Consequently, multiple spacers of varying heights must be designed to accommodate required heights. 2. It lacks independent fixing capability. When the energy leads are located at a high position, they cannot be individually fixed. A series of non-grooved spacers are required below for support, transfer, and height adjustment. 3. It lacks universal adaptability. All components are tailored to each machine, lacking universal compatibility. 4. The structure is bulky and occupies a large space, leaving no room for blanking. This creates a tight space above the stator base ring plate, making it impossible to run cables or other equipment, and leaving very limited maintenance space.

[0005] Therefore, it is urgent to propose a multi-parameter matrix cluster universal combination self-locking support module to solve the problems in the existing technology that the height cannot be adjusted secondary, the adaptability is low, and the maintenance is difficult. Summary of the Invention

[0006] In view of the above facts, in order to solve the problems in the prior art that the height cannot be adjusted secondary, the adaptability is low, and the maintenance is difficult, the present invention further designs a multi-parameter matrix cluster universal combination self-locking support module.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A multi-parameter matrix cluster universal combination self-locking support module, including a first bottom support frame, a second bottom support frame, a first lead screw, a second lead screw, a first step core support, a second step core support, a stabilizing balance plate, a crossbar, a first spacer support, a second spacer support, a stator base upper ring plate, and an energy lead;

[0009] The first bottom support frame and the second bottom support frame are horizontally symmetrically welded to the stator base upper ring plate, the bottom end of the first lead screw passes through the first bottom support frame and is locked by a first locking nut, the top end of the first lead screw passes through the first stepped core support, the first spacer support, and the stabilizing balance plate in sequence from bottom to top and is locked by a third locking nut, the bottom end of the second lead screw passes through the second bottom support frame and is locked by a second locking nut, the top end of the second lead screw passes through the second stepped core support, the second spacer support, and the stabilizing balance plate in sequence from bottom to top and is locked by a fourth locking nut;

[0010] The crossbar passes horizontally through the first step core support and the second step core support, and the right side is locked by the fifth locking nut;

[0011] The energy lead is installed in a space formed by the first stepped core support, the second stepped core support, the first spacer support, the second spacer support, and the stable balance plate.

[0012] Furthermore: the first bottom support frame is an unequal-sided right-angle L-shaped metal frame, and a first threaded hole cooperating with the first lead screw is provided on the top;

[0013] The second bottom support frame is an unequal-sided right-angle L-shaped metal frame, and a second threaded hole that cooperates with the second guide screw is provided on the top.

[0014] Furthermore, the first stepped core support is a concave stepped structure, a first elastic adaptation layer is bonded to the step, two first through holes cooperating with the cross bar are symmetrically provided on the left side wall, a third threaded hole cooperating with the first lead screw is provided on the top, and the horizontal length of the first bottom side has two specifications of 120 mm and 140 mm;

[0015] The second step core support is an inward-concave stepped structure, with a second elastic adaptation layer bonded to the step. Two second through holes that cooperate with the cross bar are symmetrically set on the right side wall, and a fourth threaded hole that cooperates with the second guide screw is set on the top. The horizontal length of the second bottom edge has two specifications of 120mm and 140mm.

[0016] Furthermore: the first step core support and the second step core support are both made of Tongma epoxy glass fiber, and the first elastic adaptation layer and the second elastic adaptation layer are both made of soft rubber.

[0017] Furthermore: the stable balance plate is composed of an insulating pressure plate and an elastic pad, the elastic pad is bonded to the bottom of the insulating pressure plate, a third through hole is provided on the left side of the insulating pressure plate to cooperate with the first guide screw, and a fourth through hole is provided on the right side of the insulating pressure plate to cooperate with the second guide screw.

[0018] Furthermore: the elastic pad is made of rebound rubber material.

[0019] Furthermore: the first spacing support is short cylindrical, and a fifth threaded hole is provided at the center thereof for cooperating with the first lead screw;

[0020] The second spacing support is in the shape of a short cylinder, and a sixth threaded hole is provided at the center thereof for cooperating with the second lead screw.

[0021] Furthermore: the first spacing support and the second spacing support are both made of polyimide material.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention adopts the principle of multi-parameter matrix cluster and matrix modular design, so that a set of products can be adapted to all 100,000-kilowatt to 400,000-kilowatt pumped-storage power generation motor units with four parallel branches currently on the market, achieving universality and serialization, and significantly reducing product costs.

[0024] 2. When different units use the same energy lead size but different distribution heights, number of layers and inter-layer spacing, this can be achieved by directly adjusting the number, height and spacing of the first-step core supports and the second-step core supports. The first-step core supports and the second-step core supports can be infinitely adjusted in the height direction. At the same time, each layer is fixed separately, and there is no requirement for supporting force transmission between the upper and lower layers. The spacing between any two layers of energy leads no longer needs to be forcibly fixed and can be adjusted to an appropriate position according to actual needs.

[0025] 3. For units with different energy lead sizes, first adjust the distance between the first bottom support frame and the second bottom support frame according to the width of the energy lead, and select the first step core support and the second step core support of appropriate sizes as needed to achieve adaptation.

[0026] 4. When it is necessary to adapt to energy leads of different heights, since the first-step core support and the second-step core support in the present invention are both infinitely adjustable, they can be adjusted to any height according to site needs, and the spacing between different layers can also be adjusted in the same way, which is very convenient.

[0027] 5. The present invention significantly reduces the scale of spare parts reserves. A spare parts center serving 5 power stations and 30 units only needs to reserve spare parts of the same specifications and models. The spare parts rate can be reduced by 90%, significantly reducing the procurement and storage costs of power companies.

[0028] 6. After the present invention is installed and used, more space is left. Except for the first-step core support and the second-step core support set at the necessary positions to support the energy leads, the rest of the positions are blank, which can be used to lay cables and set other equipment, and is also conducive to inspection and maintenance, thereby increasing the operating space.

[0029] 7. The present invention is more convenient to install. Only the first bottom support frame and the second bottom support frame need to be welded on site, and the rest are threaded connections, eliminating the need for matching brackets in traditional structures. The inter-layer adjustment amount is larger and more linear, and can be adjusted steplessly, which greatly improves the installation efficiency.

[0030] 8. The locking structures used in the present invention are all threaded and limit locking, the overall structure is more stable, and has better tolerance to adverse factors such as unit vibration, which can significantly improve the overall stability of the unit.

[0064] More specifically, the first stepped core support 7 and the second stepped core support 8 are both made of Tongma epoxy glass fiber, and the first elastic adaptation layer 21 and the second elastic adaptation layer 22 are both made of soft rubber.

[0071] More specifically, the first spacing support 14 and the second spacing support 30 are both made of polyimide.

[0072] More specifically: when the height needs to be adjusted to fit the energy lead 16, simply rotate the first step core support 7 and the second step core support 8 to the required position, and then use the crossbar 12 and the fifth locking nut 13 to lock them;

[0073] The first step core support 7 and the second step core support 8 are both steplessly adjustable and can be adjusted up and down to any given position.

[0074] More specifically: when it is necessary to adapt energy leads 16 of different sizes, first adjust the distance between the first bottom support frame 1 and the second bottom support frame 2 according to the width of the energy lead 16, and select the first step core support 7 and the second step core support 8 of appropriate sizes as needed, so as to quickly achieve adaptation.
