Description

Technical Field

[0001] This invention relates to the field of hydropower engineering technology, and more specifically, to a standardized mounting bracket system for limit switches used in generator brake dampers. Background Technology

[0002] Limit switches (also known as travel switches) are widely used in industrial automation, mechanical control, material handling, and construction machinery to detect the position of objects, the end of their travel, or as safety interlock devices. Their main functions include: position detection – accurately sensing the position or overshoot of a moving object; travel limiting – issuing a signal when the equipment reaches its physical limit position to prevent damage from overtravel; sequence control – serving as an input signal to a logic control system to trigger the next action; safety interlock – ensuring that protective doors are closed, safety covers are in place, or personnel are in a safe area before the equipment can start or continue operating; counting – detecting the number of times an object passes or reciprocates (requires a counter or PLC); signal conversion – converting mechanical displacement into electrical switching signals (on / off) for PLCs, relays, contactors, or other control components to read.

[0003] The limit switch consists of a high-strength engineering plastic housing, a transmission mechanism (plunger type, roller plunger), an operating mechanism, a micro switch, terminals (COM common terminal, NO normally open, NC normally closed), and seals. Its working principle is based on mechanical triggering and electrical switching of the limit switch, namely: Initial state (no action) – the micro switch is in its natural state; Triggering action – the monitored moving object contacts the roller at the top of the plunger, the force applied by the object overcomes the resistance of the internal spring, pressing the plunger axially into the switch, which is transmitted and amplified through the internal operating mechanism, ultimately driving the button or lever of the micro switch; Switch switching – COM and NC terminals disconnect, COM and NO terminals close; Signal output – the change in switch state (NC open, NO closed) generates a change in electrical signal; Reset – when the moving object moves away and no longer applies pressure to the plunger, the switch output signal returns to the initial state, indicating that the object has "left," the elasticity of the internal spring pushes the plunger back to its original state, thereby driving the operating mechanism and the micro switch back to their natural state, ultimately achieving signal reset. In this way, the switching control of the circuit can be achieved by triggering the limit switch to open or close it by the travel of the object being measured.

[0004] The wind damper device of a hydropower station unit is a key piece of equipment to ensure the safe operation of the unit. During the start-up and shutdown processes, the status of the wind damper device needs to be assessed. The status feedback signal of the wind damper device directly determines whether the unit can meet the start-up conditions and affects the entire start-up and shutdown process.

[0005] Limit switches are the core component of the damper status feedback system. Their stability and sensitivity directly affect the reliability of the damper device. Taking a common configuration as an example, a unit is usually equipped with twelve dampers, and each damper requires two limit switches to detect its lowering and raising. It can be seen that the damper device of a hydropower station unit requires a large number of limit switches.

[0006] Currently, the installation of limit switches mainly relies on manual work by maintenance personnel, with angle adjustments and distance control based on experience. Practice shows that this experience-dependent installation method has significant shortcomings: firstly, installation accuracy is difficult to guarantee; secondly, the uniformity of all limit switches is poor, and individual experience cannot be standardized into a routine. Furthermore, the environments in which damper devices are typically located are harsh, further hindering installation and subsequent maintenance, ultimately leading to low maintenance efficiency and difficulty in guaranteeing the long-term operational stability of the limit switches. Summary of the Invention

[0007] The present invention aims to provide a standardized mounting bracket system for limit switches used in generator brake dampers, in order to solve the problems of existing technologies that rely on experience to install limit switches, which makes it difficult to guarantee installation accuracy, resulting in poor uniformity among all limit switches and large positioning deviations.

[0008] This invention is achieved using the following technical solution: This invention provides a standardized mounting bracket system for limit switches of generator brake dampers, comprising multiple mounting brackets, each mounting bracket including a fixed base, a horizontal adjustment component, a vertical adjustment component, and a limit switch mounting base, wherein all the fixed bases are respectively installed at fixed anchor points on the damper base; The limit switch mounting base is slidably connected to the horizontal adjustment assembly, and both ends of the horizontal adjustment assembly are detachably connected to the fixed base; The limit switch mounting base is slidably connected to the vertical adjustment assembly, and both ends of the vertical adjustment assembly are detachably connected to the fixed base; The limit switch mounting base slides on the horizontal adjustment component and the vertical adjustment component to achieve horizontal and vertical position adjustment, respectively. The limit switch mounting base is used to install limit switches.

[0009] As a preferred technical solution: The horizontal adjustment component includes a horizontal guide rail, which is arranged horizontally. The vertical adjustment component includes a vertical guide rail, which is arranged vertically and is perpendicular to the horizontal guide rail.

[0010] As a preferred technical solution: The relative positions of each fixed anchor point on the wind gate base and its corresponding wind gate baffle are kept consistent.

[0011] As a preferred technical solution: The horizontal and vertical guide rails are provided with scales.

[0012] As a preferred technical solution: The limit switch mounting base is equipped with a limit switch crank arm angle adjustment and length adjustment mechanism. The limit switch crank arm angle adjustment and length adjustment mechanism includes an arc-shaped plate with an angle scale. The arc-shaped plate is arranged on one side of the limit switch crank arm, and the angle scale is used to indicate the angle of the limit switch crank arm.

[0013] As a preferred technical solution: The curved plate is also provided with a length scale, which is used to indicate the length of the limit switch crank arm.

[0014] As a preferred technical solution: The limit switch mounting base has a mounting groove on one side, and the arc-shaped plate is connected to the bottom of the mounting groove by a telescopic rod; One end of the telescopic rod is fixedly connected to the bottom of the mounting slot, and the other end of the telescopic rod is fixedly connected to one side of the arc-shaped plate. The telescopic rod is used to allow the arc-shaped plate to be stored in the mounting slot or extend out of the mounting slot.

[0015] As a preferred technical solution: After the limit switch is adjusted to the correct position, the positioning pin passes through the limit switch mounting base, the arc-shaped plate, the vertical guide rail, and the horizontal guide rail in sequence to position each structural component.

[0016] As a preferred technical solution: Both ends of the horizontal guide rail and the vertical guide rail are respectively connected to crank arm protection seats, and the crank arm protection seats are connected to the fixed base; The crank arm protection seat is made of flexible material.

[0017] As a preferred technical solution: The crank arm protection seats connected to both ends of the vertical guide rail also serve as limit seats for the limit switch crank arm, limiting the extreme positions of the limit switch crank arm rotation.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The mounting bracket system of this invention enables standardized and high-precision installation of limit switches. By quantifying the horizontal, vertical (i.e., vertical direction) and angle of the limit switches, it is beneficial to adjust multiple limit switches to be consistent, so that the installation positions of all limit switches in three-dimensional space are highly consistent, which significantly improves the installation and positioning accuracy of the limit switches (up to ±0.5 mm / ±0.5° level), ensures the overall reliability of the system, fundamentally solves the problems of large positioning deviation and poor consistency caused by traditional manual installation, realizes the simplification, precision and data-driven maintenance of generator brakes, and improves the accuracy and reliability of generator brake status feedback.

[0019] 2. The mounting bracket system of this invention provides multi-dimensional high-precision adjustment capabilities. Through the cooperation of the limit switch mounting base with the horizontal and vertical guide rails, the limit switches can be finely and flexibly adjusted within space. Due to its adjustability, the mounting bracket system of this invention can accurately adapt to the installation space and triggering requirements of different models and specifications of air dampers, ensuring that the final triggering position of all limit switches is accurate and consistent, significantly improving the accuracy and response speed of braking action.

[0020] 3. The mounting bracket system of this invention optimizes structural design and improves maintainability and efficiency. This invention adopts a modular and user-friendly structural design, making the installation, disassembly, adjustment, and subsequent maintenance of the limit switch and its adjusting mechanism extremely simple and quick. This design significantly improves installation and maintenance efficiency, effectively reducing labor and time costs. Simultaneously, the optimized structure enhances overall rigidity and stability, directly improving the reliability and durability of the braking system during long-term operation.

[0021] 4. The mounting bracket system of the present invention is made of heat-resistant, moisture-proof and high-protection materials, which can ensure its long-term stable use in harsh environments, significantly improving its triggering reliability, repeatability error and service life, and enhancing the stability and reliability of the braking system.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0028] Example 1 like Figure 1 and Figure 2 As shown, this embodiment proposes a standardized mounting bracket system for limit switches of generator brake dampers, including multiple mounting brackets. Each mounting bracket includes a fixed base 1, a horizontal adjustment component, a vertical adjustment component, and a limit switch mounting base 4. The fixed base 1 is fixedly connected to the damper base 14.

[0029] The mounting bases 1 of all the mounting brackets are respectively installed at fixed anchor points on the air damper base 14, and the relative position between each fixed anchor point and its corresponding air damper baffle 10 is consistent. In this way, the installation position of the fixed base 1 can be accurately guaranteed.

[0030] Preferably, all the mounting brackets' fixing bases 1 are installed on the same straight line in the same plane on the air damper base 14, and the distance between all the fixing bases 1 and their corresponding air damper baffles 10 is equal.

[0031] The horizontal adjustment assembly includes a horizontal guide rail 2, which is arranged horizontally. The limit switch mounting base 4 is slidably connected to the horizontal guide rail 2. Both ends of the horizontal guide rail 2 are detachably connected to the fixed base 1. The height of the horizontal guide rail 2 on the fixed base 1 is adjustable. After the height of the horizontal guide rail 2 is adjusted to the correct position, both ends are then connected to the fixed base 1.

[0032] The vertical adjustment assembly includes a vertical guide rail 3, which is arranged vertically and perpendicular to the horizontal guide rail 2. The limit switch mounting base 4 is slidably connected to the vertical guide rail 3. Both ends of the vertical guide rail 3 are detachably connected to the fixed base 1. The horizontal position of the vertical guide rail 3 on the fixed base 1 is adjustable. After the horizontal position of the horizontal guide rail 2 is adjusted to the correct position, both ends of the horizontal guide rail 2 are then connected to the fixed base 1.

[0033] The limit switch mounting base 4 is used to install limit switches.

[0034] In use, firstly, set fixed anchor points for the mounting brackets on the air damper base 14, ensuring that the relative positions of each fixed anchor point and its corresponding air damper baffle 10 are consistent. Then, install all the fixed bases 1 of the mounting brackets at their respective fixed anchor points on the air damper base 14, ensuring that all fixed bases 1 are located on the same straight line within the same plane of the air damper base 14, and that the spacing between all fixed bases 1 and their corresponding air damper baffles 10 is equal, laying the foundation for standardized installation of the entire mounting bracket system. Next, install the limit switch onto the corresponding limit switch mounting base 4, adjusting the position of the limit switch to correspond to the position of the air damper baffle 10, so that the air damper baffle 10 is located above the limit switch crank arm 13. The air damper baffle 10 is fixedly installed at the bottom of the air damper 11, and the position of the air damper baffle 10 on the air damper 11 is standard. For example, horizontally upward, adjust the limit switch mounting base 4 to the midpoint of the horizontal guide rail 2; vertically upward, adjust the limit switch to a position where the limit switch ball is 5mm away from the air damper 11.

[0035] First, the installation position of the limit switch can be verified using measuring tools to simulate actual working conditions and check whether the triggering state of the limit switch meets the requirements. During operation, check whether the status feedback of each limit switch is accurate, consistent and timely. If it does not meet the requirements, adjust the position of the limit switch until it meets the requirements, record the installation parameters, and then put it into actual use.

[0036] The state of the air damper 11 is determined by the interaction between the air damper baffle 10 and the limit switch crank arm 13. When the air damper 11 is lowered, the air damper baffle 10 contacts the limit switch crank arm 13, triggering the limit switch to operate. When the air damper 11 is raised, the air damper baffle 10 disengages from the limit switch crank arm 13, and the limit switch resets (returns to its natural state). The air damper 11 is the generator brake air damper 11.

[0037] Since all the mounting brackets' fixed bases 1 are installed on the same straight line in the same plane on the air damper base 14, the consistency of all fixed bases 1 in the horizontal X direction is ensured; since the distance between all fixed bases 1 and their corresponding air damper baffles 10 is equal, the relative position of the fixed bases 1 and their corresponding air damper baffles 10 is ensured. Since the horizontal guide rail 2 and the vertical guide rail 3 are detachably mounted on the fixed base 1, when it is necessary to adjust the vertical position of the limit switch mounting base 4, the connection between the two ends of the horizontal guide rail 2 and the fixed base 1 is loosened, and the limit switch mounting base 4 is slid along the vertical guide rail 3. The horizontal guide rail 2 and the limit switch mounting base 4 move up and down together. After adjustment, the two ends of the horizontal guide rail 2 are fixed to the fixed base 1. When it is necessary to adjust the horizontal Y-axis position of the limit switch mounting base 4, the connection between the two ends of the vertical guide rail 3 and the fixed base 1 is loosened, and the limit switch mounting base 4 is slid along the horizontal guide rail 2. The vertical guide rail 3 and the limit switch mounting base 4 move left and right together. After adjustment, the two ends of the vertical guide rail 3 are fixed to the fixed base 1. In this way, the vertical and horizontal Y-axis adjustments of the limit switch mounting base 4 are realized. When the adjustment amount of all mounting brackets is set to be consistent, the horizontal and vertical positions of all limit switch mounting bases 4 are unified, that is, the horizontal and vertical positions of all limit switches are unified. The convenient fit between the limit switch mounting base 4 and the horizontal guide rail 2 and vertical guide rail 3 facilitates easy adjustment of the movement, which is controllable rather than determined by experience. Therefore, using the mounting bracket of this invention, the limit switches achieve high installation accuracy and are easy to adjust precisely. Furthermore, by controlling the adjustment of each mounting bracket, all limit switches can be adjusted to a uniform state, quantifying and ensuring consistency in their installation positions. This accurately reflects the lifting or lowering state of the air damper 11, thereby reducing manual labor intensity, improving work efficiency, and enhancing equipment operational stability. The horizontal X-axis refers to... Figure 2 The direction perpendicular to the paper, the horizontal Y direction refers to Figure 2 The horizontal direction in the middle.

[0038] Preferably, the two ends of the horizontal guide rail 2 and the vertical guide rail 3 are respectively connected to the fixed base 1 by screws, the screws are detachable, and the fixed base 1 has multiple screw holes.

[0039] Preferably, the limit switch is mounted on the limit switch mounting base 4 by screws.

[0040] Preferably, the horizontal guide rail 2 and the vertical guide rail 3 are provided with scales to precisely adjust the horizontal and vertical positions of the limit switch mounting base 4.

[0041] Preferably, the limit switch mounting base 4 is provided with a positioning reference point, which provides a reference for the installation of the limit switch, so that the limit switch body 12 can be accurately installed on the limit switch mounting base 4.

[0042] Preferably, after the horizontal guide rail 2 and the vertical guide rail 3 are adjusted into place, the positioning pin 6 passes through the limit switch mounting base 4, the vertical guide rail 3 and the horizontal guide rail 2 in sequence to fix the horizontal guide rail 2 and the vertical guide rail 3 relative to each other. The horizontal guide rail 2 and the vertical guide rail 3 are fixed on the one hand by the positioning pin 6, and on the other hand by the connection of its two ends to the fixed base 1.

[0043] Example 2 like Figures 1-4 As shown, the difference between this embodiment and Embodiment 1 is that: Preferably, the limit switch mounting base 4 is equipped with a limit switch arm angle and length adjustment mechanism 5. The limit switch arm angle and length adjustment mechanism 5 includes an arc-shaped plate with angle markings. The arc-shaped plate is positioned on one side of the limit switch arm 13. The angle markings indicate the angle of the limit switch arm 13. The limit switch arm 13 can be adjusted to a specified angle as needed, and then other limit switch arms 13 can also be adjusted to the same angle, thus achieving consistency in the angles of all limit switch arms 13 and further ensuring the uniformity of all limit switch installations. For example, the angle of the limit switch arm 13 can be adjusted to 40° with the horizontal plane.

[0044] The arc-shaped plate is also equipped with a length scale, which indicates the length of the limit switch crank arm 13. The limit switch crank arm 13 can be adjusted to a specified length as needed, and then other limit switch crank arms 13 can also be adjusted to that length, thus achieving consistency in the length of all limit switch crank arms 13. This further ensures the uniformity of installation of all limit switches, enabling all accurate limit switches to accurately reflect the raised or lowered state of all air dampers 11. This invention quantifies the adjustment of the position, crank arm angle, and length of the limit switches, ensuring the accuracy of limit switch installation and avoiding the problem of low accuracy caused by relying on experience for adjustment, achieving standardized adjustment. Furthermore, the adjustment method is simple, allowing for quick and accurate adjustment, reducing manual labor intensity, improving work efficiency, and enhancing equipment operational stability.

[0045] Preferably, a mounting groove is provided on one side of the limit switch mounting base 4. The arc-shaped plate is connected to the bottom of the mounting groove via a telescopic rod 9. Specifically, one end of the telescopic rod 9 is fixedly connected to the bottom of the mounting groove, and the other end of the telescopic rod 9 is fixedly connected to one side of the arc-shaped plate. The length of the telescopic rod 9 is adjustable by telescoping, and its length can be freely varied. Both the telescopic rod 9 and the arc-shaped plate can be stored in the mounting groove. When it is necessary to adjust the angle and length of the limit switch crank arm 13, the arc-shaped plate is pulled out of the mounting groove, and at the same time, the length of the telescopic rod 9 increases.

[0046] The telescopic rod 9 is existing technology. For example, the telescopic rod 9 includes a multi-section nested sliding sleeve, or other telescopic rods 9 that can achieve length change can also be used.

[0047] Preferably, the telescopic rod 9 is connected to the limit switch mounting base 4 and the arc-shaped plate by bolts.

[0048] Preferably, the positioning pin 6 can also pass through the arc-shaped plate to fix the arc-shaped plate. When it is necessary to pull out the arc-shaped plate, the positioning pin 6 must be removed first.

[0049] During use, not only the position of the limit switch is adjusted, but also the angle and length of the limit switch crank arm 13 are adjusted.

[0050] During verification, the range of motion of the limit switch crank arm 13 also needs to be tested.

[0051] The quality control standards during validation include: 1. Installation accuracy requirements: Horizontal position deviation: ±0.5mm, vertical position deviation: ±0.5mm, angle deviation: ±0.5°.

[0052] 2. Functional verification requirements: Trigger reliability: 100%, repeatability error: ≤0.1mm, service life: ≥10 years.

[0053] 3. Environmental adaptability requirements: Operating temperature: -20℃~60℃, relative humidity: ≤95%, protection level: IP54.

[0054] The standardized mounting bracket system for limit switches of this invention enables standardized installation of all limit switches. The position (including vertical and horizontal) of each limit switch, as well as the angle and length of the crank arm, can be easily adjusted. Precise adjustment of the limit switches in the horizontal and vertical directions (i.e., vertically) and the angle and length of the crank arm is possible, ensuring that all limit switches are adjusted uniformly. This solves the problems of low accuracy, large positioning deviations, and poor consistency caused by traditional manual installation, improving the accuracy and reliability of generator brake status feedback. The modular design makes installation and disassembly simple, and the adjustment method convenient, improving installation and maintenance efficiency and effectively reducing labor and time costs. The overall structure of the mounting bracket is stable, with high overall rigidity and stability, enhancing the reliability and durability of the braking system during long-term operation.

[0055] Example 3 The difference between this embodiment and Embodiment 1 is that: Preferably, both ends of the horizontal guide rail 2 and the vertical guide rail 3 are respectively connected to a crank arm protection seat 7, which can be connected to the fixed base 1 by screws. The surface of the crank arm protection seat 7 is higher than the limit switch mounting surface of the limit switch mounting base 4, and the crank arm protection seat 7 is provided with a flexible material 8 to protect the crank arm.

[0056] Preferably, the flexible material 8 may be, but is not limited to, a heat-resistant and moisture-proof rubber material.

[0057] The crank arm protection seats 7 connected to both ends of the vertical guide rail 3 also serve as limit seats for the limit switch crank arm 13, restricting the extreme position of the limit switch crank arm 13 rotation and preventing the limit switch crank arm 13 from rotating excessively. The crank arm protection seats 7 connected to both ends of the horizontal guide rail 2 will not interfere with the limit switch crank arm 13.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
