[0038] Example 1

[0039] A type of surge arrester for power plants. Figure 1 A schematic diagram of the overall structure of one embodiment of the present invention is shown; Figure 2 A side view of the overall structure of an embodiment of the present invention is shown; Figure 3 A cross-sectional view of the overall structure of an embodiment of the present invention is shown, as follows.Figure 1 , Figure 2 and Figure 3 As shown, it includes: mounting housing 1, moving mechanism 2, guiding mechanism 3, and driving mechanism 4;

[0040] The mounting housing 1 is positioned on the target plane, serving as the foundational load-bearing structure for the entire surge arrester device. Located on the target plane, it stably supports the moving mechanism 2, guiding mechanism 3, and driving mechanism 4, ensuring their safety and stability during operation. The mounting housing 1 can be fixed to the base or bracket using bolts, welding, or clips to meet the installation requirements of different power plant sites. The guiding mechanism 3 is connected to the mounting housing 1, and the moving mechanism 2 is connected to the surge arrester. The driving mechanism 4 drives the moving mechanism 2 to move along the guiding direction of the guiding mechanism 3. The guiding mechanism 3, connected to the mounting housing 1, constrains and guides the movement of the moving mechanism 2, with its guiding direction being vertical. The guiding mechanism 3 can be in the form of a linear guide rail, slide bar, or guide groove, ensuring that the moving mechanism 2 moves smoothly and without lateral deviation in the vertical direction, thereby realizing the height adjustment function of the surge arrester while ensuring the safety and reliability of the adjustment process. The moving mechanism 2 is connected to the surge arrester body, undertaking the task of moving and positioning the surge arrester in the guiding direction. The moving mechanism 2 can take the form of a slider, a lifting seat, or a screw lifting mechanism, which can work closely with the guide mechanism 3 to reduce friction and jamming. Under the action of the drive mechanism 4, the moving mechanism 2 can smoothly rise and fall in the vertical direction to meet the needs of different operating conditions or maintenance operations for adjusting the height of the surge arrester.

[0041] The guiding direction of the guiding mechanism 3 is vertical. The driving mechanism 4 includes a driving component 410, a steering component 420, and a transmission component 430. The driving component 410 provides driving force, and the steering component 420 transmits the driving force to redirect the driving force transmitted along a first direction intersecting the guiding direction to a second direction parallel to the guiding direction. The transmission component 430 transmits the driving force output by the steering component 420 to the moving mechanism 2, causing the moving mechanism 2 to move in the vertical direction. The driving mechanism 4 includes a driving component 410, a steering component 420, and a transmission component 430. The driving component 410 provides the power source for the entire mechanism and can be in the form of an electric motor, hydraulic cylinder, or pneumatic cylinder. The steering component 420 redirects the driving force transmitted along a first direction intersecting the guiding direction to a second direction parallel to the guiding direction, achieving effective force conversion and ensuring that the driving force is transmitted in the vertical direction. The transmission component 430 transmits the redirected driving force to the moving mechanism 2, enabling the moving mechanism 2 to move smoothly in the vertical direction. Through the above design, the drive mechanism 4 can efficiently and safely complete the adjustment action of the surge arrester.

[0042] Figure 4This is a schematic diagram of the drive component and drive mounting bracket structure according to an embodiment of the present invention, as shown below. Figure 4 As shown, the drive component 410 includes a drive motor 411, which is connected to the worm gear 422 via an insulated coupling. The drive component 410 includes a drive motor 411, which is connected to the worm gear 422 via an insulated coupling to achieve smooth power transmission. The drive motor 411 can be an AC or DC motor, or a servo motor or stepper motor can be selected according to site conditions to meet different power and speed control requirements. The output shaft of the motor is connected to the worm gear 422 via an insulated coupling. The insulated coupling can effectively transmit power and provide a certain buffer and deviation compensation between the motor and the worm gear, avoiding mechanical jamming or damage caused by installation errors or thermal expansion. It also has a certain electrical insulation function, improving the safety of the device.

[0043] The system also includes a drive mounting bracket 5, which is disposed on the target plane, and the drive component 410 is disposed within the drive mounting bracket 5. To fix the drive component 410 and ensure its stable operation, the present invention provides a drive mounting bracket 5. The drive mounting bracket 5, disposed on the target plane, can be a welded or cast steel plate structure to ensure sufficient load-bearing capacity and vibration resistance. The drive component 410 is disposed within the drive mounting bracket 5 and fixed by bolts, slots, or locating pins, ensuring accurate positioning, minimal vibration, and stable operation of the drive motor and worm gear during operation. The drive mounting bracket 5 also provides protection, protecting the motor and transmission components from dust, moisture, and external impacts, improving the durability and reliability of the device. In specific implementations, the drive mounting bracket 5 can be customized according to the space of the power plant site and the structural characteristics of the surge arrester. For example, multi-stage adjustment holes or sliding slots can be provided to allow for fine-tuning of the position of the drive component 410 during installation and commissioning.

[0044] Furthermore, in this embodiment, Figure 5 A schematic diagram of the moving mechanism and guiding mechanism according to an embodiment of the present invention is shown. Figure 6 A cross-sectional view of the moving mechanism and guiding mechanism structure according to an embodiment of the present invention is shown, as follows: Figure 5 and Figure 6As shown, the guiding mechanism 3 includes a guide rod 310, the length direction of which is perpendicular to the mounting shell 1. The guide rod 310 passes through the moving mechanism 2 and guides and limits its movement, allowing the moving mechanism 2 to move vertically. One end of the guide rod 310 is connected to the mounting shell 1 via a fixed seat, while the other end can extend freely or be reinforced by an end fixing member, thus forming a stable straight guiding path. The guide rod 310 adopts a circular or square cross-section structure. Circular guide rods have the advantages of low friction and smooth movement, while square or polygonal guide rods have torsional resistance, and can be selected according to application requirements. To meet the corrosion resistance and weather resistance requirements of the power plant operating environment, the guide rod 310 is preferably made of high-strength alloy steel, stainless steel, or carbon steel with a chrome-plated surface and a sprayed anti-corrosion layer to improve its service life. The moving mechanism 2 is sleeved on the outside of the guide rod 310 and achieves vertical lifting movement through sliding cooperation with the guide rod 310. Specifically, the moving mechanism 2 may include a sliding sleeve, a moving seat, or a lifting frame. A high-precision fit clearance is provided between the inner wall of the sliding sleeve and the outer surface of the guide rod 310, ensuring smooth movement while preventing wobbling due to excessive clearance. To further reduce frictional resistance and improve movement stability, the inner wall of the sliding sleeve may also be equipped with a wear-resistant bushing, ball bearing, or self-lubricating bearing to achieve low-resistance, high-precision linear guidance.

[0045] In practical applications, the number of guide rods 310 can be adjusted according to the weight and stability requirements of the surge arrester. A single guide rod is suitable for the adjustment structure of light or medium-sized surge arresters, while for larger and heavier surge arresters, two or more guide rods can be arranged in parallel to form multi-point guidance, improve the stability of movement, and avoid deviation or tilting. The guide rods can be fixed together by connecting beams to further enhance the overall rigidity and seismic resistance.

[0046] The external surface of the moving mechanism 2 is typically equipped with an installation interface for connecting to the surge arrester body, such as bolt holes, clamping devices, or welded connection seats, allowing the surge arrester to be securely mounted on the moving mechanism 2. Through the action of the drive mechanism 4, the moving mechanism 2 moves smoothly in the vertical direction under the constraint of the guide rod 310, thereby adjusting the height of the surge arrester. Throughout the adjustment process, the guide rod 310 acts as a guide and limiter for the moving mechanism 2, preventing lateral deviation and ensuring the straightness of the movement path, thus ensuring that the surge arrester always remains vertically stable.

[0047] To enhance practicality, the present invention employs protective and lubrication structures at the contact points between the moving mechanism 2 and the guide rod 310. For example, sealing rings or dust covers can be installed at both ends of the sliding sleeve to effectively prevent dust, moisture, and other impurities from entering the guiding mating parts, thus avoiding increased frictional resistance or impaired movement due to environmental factors. Simultaneously, a wear-resistant coating can be applied to the surface of the guide rod 310, or an oil groove can be embedded inside the sliding sleeve to ensure good lubrication during long-term operation, thereby extending the service life of the device.

[0048] Furthermore, in this embodiment, the moving mechanism 2 includes a transmission plate 210 and a connecting plate 220, which are disposed at both ends of the moving mechanism 2. The connecting plate 220 is connected to the surge arrester. The connecting plate 220 and the transmission plate 210 are rotatably connected to the transmission component 430, respectively. Driven by the transmission component 430, the moving mechanism 2 and the surge arrester are moved up and down along the guiding direction of the guide mechanism 3. The moving mechanism 2 includes a transmission plate 210 and a connecting plate 220, which are respectively disposed at the upper and lower ends of the moving mechanism 2, forming a stable load-bearing and transmission unit. The transmission plate 210 is mainly used to cooperate with the transmission component 430 to achieve effective transmission of driving force; the connecting plate 220 is used to fixally connect with the surge arrester body, thereby ensuring that the surge arrester can move up and down as a whole with the moving mechanism 2 during transmission. Specifically, the transmission plate 210 is usually made of high-strength metal plate, and a rotating connection hole is opened in its center to achieve a reliable rotating connection with the transmission component 430. Driven by the transmission component 430, the transmission plate 210 can efficiently transmit driving force to the entire moving mechanism 2 while maintaining stability. To improve transmission efficiency and service life, the surface of the transmission plate 210 can be treated with wear-resistant materials, such as hard chrome plating, spraying a wear-resistant layer, or using surface carburizing to enhance wear resistance. The connecting plate 220 is located at the other end of the moving mechanism 2 and mainly undertakes the task of fixing it to the surge arrester. The structural form of the connecting plate 220 can vary depending on the shape design of the surge arrester. For example, it can be designed as a flat plate structure with multiple bolt holes for bolt connection to the surge arrester base; it can also be designed as a slotted or clamped structure to fix the surge arrester by clamping, to meet the installation requirements of surge arresters of different models and weights. The connecting plate 220 is also connected to the transmission component 430 by a rotating connection. This structure ensures smooth transmission during lifting and lowering, and avoids stress concentration due to excessive constraints, thus improving overall reliability and durability. In an embodiment of the present invention, the transmission plate 210 and the connecting plate 220 are connected by a frame or sliding sleeve structure and form a cooperative relationship with the guide rod 310 of the guide mechanism 3.

[0049] Furthermore, in this embodiment, the transmission plate 210 includes a guide groove 211, which is adapted to the guide rod 310. The guide groove 211 is used to accommodate and fit around the outside of the guide rod 310, so as to slide with the guide rod 310 during the lifting and lowering of the moving mechanism 2, thereby limiting and guiding the moving mechanism 2. The transmission plate 210 not only transmits driving force but also undertakes the functions of guidance and limitation. Specifically, the transmission plate 210 is provided with a guide groove 211, which is opened in the vertical direction, and its shape and size are adapted to the guide rod 310. When installed, the guide groove 211 is fitted around the outside of the guide rod 310, so that the transmission plate 210 can move smoothly in the vertical direction under the constraint of the guide rod 310. The guide groove 211 and the guide rod 310 maintain a precise fit, which satisfies low-friction sliding while preventing the transmission plate 210 from lateral swaying or deviating, thereby ensuring the accuracy of the movement path of the moving mechanism 2.

[0050] The transmission plate 210 includes a transmission groove 212, the inner peripheral wall of which is provided with a first thread. The transmission component 430 includes a screw 431, the screw 431 including a second thread. The first thread and the second thread are adapted to each other. The screw 431 rotates under the drive of the drive component 410, and drives the transmission plate 210 to move up and down along the guide direction of the guide mechanism 3 through the first thread and the second thread. The transmission plate 210 is also provided with a transmission groove 212, which is usually a round hole or a cylindrical hole, and its inner peripheral wall is machined with a first thread. In conjunction with this, the transmission component 430 includes a screw 431, the outer surface of which is provided with a second thread corresponding to the first thread. The first thread and the second thread form a transmission pair through threaded engagement. Under the drive of the drive component 410, the screw 431 can continuously rotate along its own axis. During the rotation, due to the engagement of the first thread and the second thread, axial displacement will occur, thereby driving the transmission plate 210 to move up and down along the guide direction of the guide mechanism 3. The threaded transmission method has advantages such as smooth transmission, precise positioning, and strong load-bearing capacity. By rationally designing the lead and tooth profile of the thread, the lifting speed and adjustment accuracy of the transmission plate 210 can be controlled. For example, when a larger torque and higher load-bearing capacity are required, a trapezoidal thread or a rectangular thread can be used; when higher transmission efficiency is required, a ball screw structure can be used, with circulating balls set between the transmission groove 212 and the screw 431 to significantly reduce friction loss and improve transmission accuracy and lifespan. In specific implementation, one end of the screw 431 is rotatably connected to the mounting housing 1 or the drive mounting bracket 5 via a bearing.

[0051] Furthermore, in this embodiment, the steering component 420 includes a worm gear 421 and a worm 422. The worm 422 is connected to the output end of the drive component 410. The worm gear 421 meshes with the worm 422, and the worm gear 421 is coaxially fixed with the screw 431. When the drive component 410 drives the worm 422 to rotate, the worm gear 421 drives the screw 431 to rotate, thereby driving the moving mechanism 2 to rise and fall vertically. The worm 422 is connected to the output end of the drive component 410, for example, the motor output shaft is fixedly connected to the worm 422 through a coupling, ensuring that the drive motor can stably drive the worm 422 to rotate when it is running. The worm gear 421 meshes with the worm 422 to form a worm gear transmission pair. The helical tooth surface of the worm 422 meshes tightly with the tooth surface of the worm gear 421, which can change the power direction from the horizontal direction to the vertical direction during rotation, thereby realizing a 90° steering transmission of power. The worm gear 421 and the screw 431 are coaxially fixed and can be connected by a key, spline, or interference fit to make the worm gear 421 and the screw 431 a single unit. When the drive component 410 drives the worm 422 to rotate, the worm gear 421 rotates under meshing action, driving the screw 431, which is fixedly connected to it, to rotate synchronously. The rotation of the screw 431 is further converted into linear displacement of the transmission plate 210 along the guide direction through the threaded pair with the transmission plate 210, thereby realizing the lifting and lowering movement of the moving mechanism 2 and the surge arrester.

[0052] Furthermore, this embodiment also includes a water-draining mechanism 6, which is disposed on the surface of the mounting housing 1. The water-draining mechanism 6 is positioned corresponding to the moving mechanism 2 and is used to collect and drain rainwater as it flows along the outer wall of the mounting housing 1. Since power plant surge arresters and their installation devices are typically directly exposed to the outdoor environment, rainwater or condensate easily flows along the outer wall of the mounting housing 1. If not guided and drained in time, it can easily accumulate in the guide groove, transmission groove, or threaded area of ​​the moving mechanism 2, causing problems such as corrosion, lubrication failure, or jamming. To solve this technical problem, this embodiment adds a water-draining mechanism 6 to the surface of the mounting housing 1 at the position corresponding to the moving mechanism 2, so as to effectively collect and drain the water flowing down from the outside and prevent rainwater from directly intruding into the moving mechanism 2.

[0053] The hydrophobic mechanism 6 includes an inclined plate 610 and a water guide channel 620. The inclined plate 610 is inclined towards the water guide channel 620 from the surface of the mounting shell 1. The water guide channel 620 is provided with a drain outlet for discharging collected water outside the mounting shell 1. The inclined plate 610 is disposed on the surface of the mounting shell 1, with one end higher and the other lower, and is inclined towards the water guide channel 620. This allows rainwater to be intercepted and guided by the inclined plate 610 as it flows down the outer wall of the mounting shell 1. The inclined plate 610 can be made of stainless steel, aluminum alloy, or anti-corrosion coated steel, and its surface is covered with a hydrophobic coating to reduce water adhesion, thus making it easier for rainwater to be quickly guided. The water guide channel 620 is disposed below the inclined plate 610. The inclined plate 610 introduces water flow into the interior of the water guide channel 620. The water guide channel 620 has a groove-shaped structure, and its inner cavity can be designed as a V-shaped, U-shaped, or rectangular channel according to the actual rainfall to improve its collection capacity. A drain outlet is provided on one side of the water guide channel 620. The drain outlet is directly connected to the outside of the mounting shell 1 through a pipe or a drainage hole, so that the collected rainwater can be smoothly discharged to the outside of the device and avoid accumulation on the surface or inside of the shell.

[0054] This invention utilizes a moving mechanism, a guiding mechanism, and a driving mechanism to enable convenient vertical adjustment of the surge arrester. This allows for mechanized and automated adjustment of the arrester, avoiding the safety risks of traditional manual disassembly and high-altitude operations, and improving adjustment efficiency and ease of operation. The guiding mechanism works in conjunction with the transmission plate to ensure smooth vertical movement of the moving mechanism during lifting, preventing deviation, tilting, or jamming, and guaranteeing the adjustment accuracy and reliability of the surge arrester. The overall structure is rationally designed and suitable for power plants and other high-altitude or complex environments. The arrester position can be flexibly adjusted according to different heights and installation environments to meet various usage requirements.
