Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage static var generators, and in particular to a high-voltage static var generator that is easy to install. Background Technology

[0002] In power systems, high-voltage static var generators are widely used as important reactive power compensation devices in substations, industrial plants, and power distribution rooms. Their main functions are to improve the power factor of the power grid, stabilize the grid voltage, and reduce line losses. However, the high-voltage static var generators currently on the market have many inconveniences in the installation process, which has caused considerable trouble for practical applications.

[0003] Traditional high-voltage static var generators are mostly fixed with bolts and nuts during installation. During the installation process, operators need to use wrenches and other tools to tighten the bolts and nuts one by one. This is not only cumbersome, but also often takes 15-20 minutes to fix a single installation point, resulting in low installation efficiency. At the same time, when the equipment needs to be disassembled for maintenance or relocation, the bolts are prone to rust and stripping after long-term use, making disassembly difficult and seriously affecting the timeliness of maintenance and relocation. This method of fixing is particularly problematic for scenarios that require frequent relocation or maintenance.

[0004] In addition, high-voltage static var generators are usually large in size and weight. When inserting or removing them from the installation position, due to the lack of an effective moving auxiliary structure, sliding friction is formed between the equipment and the installation surface, resulting in high moving resistance. Operators find it difficult to accurately control the movement of the equipment during the pushing process, and improper force can easily cause the equipment to collide with the installation environment. This may not only damage the equipment and the installation environment, but also pose certain safety hazards and affect the smoothness of the insertion and removal process.

[0005] In addition, the fixing structures vary greatly in different installation scenarios, including the type of mounting carrier, the position and angle of the fixing holes, etc. The existing installation structure of high-voltage static var generators has poor adjustability and is difficult to adapt to these complex and ever-changing installation environments. When there is a deviation in the fixing hole position, it is often necessary to perform on-site drilling or cutting to adapt it, which not only increases the installation cost and time, but may also damage the installation environment, thus limiting its application in various high-voltage equipment installation scenarios.

[0006] Therefore, in view of the problems existing in the installation and disassembly efficiency, relocation convenience and installation adaptability of the existing high-voltage static var generators, there is an urgent need for a high-voltage static var generator that can solve the above problems and is easy to install. Utility Model Content

[0007] One objective of this invention is to provide a high-voltage static var generator that is easy to install. This invention allows for quick assembly and disassembly without the need for tools such as wrenches, simply by rotating the internal thread adjustment knob and handle. This effectively avoids the difficulties in assembly and disassembly caused by corrosion and stripping that can occur with traditional bolt fixing methods, significantly improving assembly and disassembly efficiency, and is particularly suitable for scenarios requiring frequent movement or maintenance. Simultaneously, the use of rollers converts sliding friction into rolling friction, reducing movement resistance and making the generator more stable and smooth when inserted and removed from the installation position. This facilitates precise control of movement by operators, protecting the equipment and the installation environment. Furthermore, through multi-dimensional adjustment of the movable seat, external threaded sleeve, and limiting plate, it is compatible with various installation carriers and can accommodate deviations in fixing hole positions, eliminating the need for on-site drilling or cutting for adaptation, thus adapting to various high-voltage equipment installation scenarios.

[0008] A high-voltage static var generator according to an embodiment of the present invention includes a generator body. Mounting seats are fixedly welded to the front ends of both sides of the generator body. Elongated through holes are symmetrically formed on the upper and lower sides of the mounting seats. Sliding grooves are symmetrically installed on the front wall of the mounting seats on both sides of the elongated through holes. A movable seat is slidably installed on the inner side of the mounting seat. An internally threaded adjustment knob is rotatably installed at the front end of the movable seat. An externally threaded sleeve is inserted into the movable seat, and the externally threaded sleeve passes through the elongated through holes. The internally threaded adjustment knob is installed on the externally threaded sleeve, and the inner thread of the internally threaded adjustment knob meshes with the outer thread of the externally threaded sleeve. A support rod is rotatably installed inside the externally threaded sleeve. A limit plate is fixedly installed at the end of the support rod, located behind the externally threaded sleeve. An adjustment handle is fixedly installed at the front end of the support rod, located in front of the externally threaded sleeve.

[0009] Furthermore, the movable seat is symmetrically provided with sliders on both outer walls, and the sliders are slidably installed in the slide grooves, so that the movable seat forms a sliding fit with the slide grooves through the sliders.

[0010] Furthermore, an annular limiting groove is provided on the front side of the interior of the movable seat, and an annular limiting block is provided on the rear side of the internal thread adjustment knob. The annular limiting block can be rotatably installed in the annular limiting groove.

[0011] Furthermore, limit blocks are symmetrically arranged on the upper and lower sides of the inner wall of the movable seat, and limit grooves are symmetrically opened on the upper and lower sides of the outer wall of the external threaded sleeve, with the limit blocks installed in the limit grooves.

[0012] Furthermore, roller seats are symmetrically arranged on both sides of the bottom of the generator body, and several sets of rollers are installed in the roller seats.

[0013] Furthermore, the number of rollers is three sets, and the three sets of rollers are respectively arranged on the front and rear sides and the middle position inside the roller seat.

[0014] Furthermore, the outer wall of the internal thread adjustment knob is provided with an anti-slip groove, and the groove extends along the axial direction of the internal thread adjustment knob.

[0015] Furthermore, the length of the support rod is the same as the length of the external threaded sleeve rod.

[0016] Furthermore, the thickness of the annular limiting block is equal to the depth of the annular limiting groove.

[0017] Furthermore, the length of the limiting block is not greater than the length of the limiting groove.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, the external thread sleeve is moved by rotating the internal thread adjustment knob, and the limit plate is made to fit the fixed structure by rotating the support rod by adjusting the handle. The entire process does not require the use of wrenches or other tools to tighten the bolts and nuts, which greatly reduces the fixing time of a single installation point. When disassembling, the internal thread adjustment knob and the adjustment handle are operated in reverse to quickly release the fixation. Compared with the disassembly difficulties caused by bolt corrosion, stripped threads, etc. during traditional disassembly, this greatly improves the disassembly and assembly efficiency, and is especially suitable for scenarios that require frequent movement or maintenance.

[0020] 2. In this utility model, when the generator is inserted into or pulled out of the installation position, the roller can convert sliding friction into rolling friction, greatly reducing the moving resistance. When the roller pushes the generator to perform the insertion or removal operation, the operator can more easily control the movement accuracy of the equipment, avoid collision between the equipment and the installation environment due to improper force, ensure that the insertion and removal process is smooth and stable, and protect the integrity of the equipment and the installation environment.

[0021] 3. In this utility model, the slider of the movable seat slides in the groove to achieve longitudinal range adjustment, the external threaded sleeve rod achieves extension and retraction through thread transmission, and the limiting plate can rotate 360° to adapt to the fixing surface at different angles, thus being compatible with various installation carriers such as walls, brackets, and ground. It can cope with installation environments with a fixed hole deviation of ±15cm, without the need for on-site drilling or cutting for adaptation. The applicable scenarios cover high-voltage equipment installation scenarios such as substations, industrial plants, and power distribution rooms. Attached Figure Description

[0034] like Figure 1-6 As shown, this utility model discloses a high-voltage static var generator that is easy to install, including a generator body 1. Mounting seats 2 are fixedly welded to the front ends of both sides of the generator body 1. Elongated through holes 3 are symmetrically opened on the upper and lower sides inside the mounting seats 2. Sliding grooves 4 are symmetrically installed on the front wall of the mounting seats 2 on both sides of the elongated through holes 3. A movable seat 7 is slidably installed inside the sliding grooves 4. An internally threaded adjustment knob 9 is rotatably installed at the front end of the movable seat 7. An externally threaded sleeve 8 is inserted into the movable seat 7, and the externally threaded sleeve 8 passes through the elongated through holes 3. The internally threaded adjustment knob 9 is installed on the externally threaded sleeve 8, and the inner thread of the internally threaded adjustment knob 9 meshes with the outer thread of the externally threaded sleeve 8. A support rod 17 is rotatably installed inside the externally threaded sleeve 8. A limit plate 15 is fixedly installed at the end of the support rod 17 and at the rear side of the externally threaded sleeve 8. An adjustment handle 16 is fixedly installed at the front end of the support rod 17 and at the front side of the externally threaded sleeve 8.

[0035] This application discloses a high-voltage static var generator that is easy to install. During installation, the generator body 1 is first moved to a suitable installation position using the rollers 6 inside the roller seats 5 on both sides of the bottom. Then, according to the position of the fixed structure in the installation environment, the position of the movable seat 7 in the slide groove 4 is adjusted. The sliders 10 on both sides of the movable seat 7 slide in the slide groove 4 to adjust the position of the movable seat 7. Next, the internal thread adjustment knob 9 is rotated. Since the inner thread of the internal thread adjustment knob 9 meshes with the outer thread of the external thread sleeve 8, and the rotation of the external thread sleeve 8 is restricted by the cooperation of the limiting block 11 and the limiting groove 14, the rotation of the internal thread adjustment knob 9 will drive the external thread sleeve 8 to move back and forth in the movable seat 7, so that the limiting plate 15 at the rear end of the external thread sleeve 8 is closer to the fixed structure. Afterwards, the support rod 17 is rotated by adjusting the handle 16. The support rod 17 drives the limiting plate 15 to rotate, so that the limiting plate 15 fits better with the fixed structure, thereby completing the installation and fixing of the generator.

[0036] The high-voltage static var generator described in this application, which is easy to install, can adapt to different installation environments and fixed structure positions by setting up a sliding movable seat 7, an adjustable external threaded sleeve 8, a rotatable support rod 17, and a limiting plate 15, greatly improving the flexibility and convenience of installation. At the same time, the precise fit between the components ensures the stability after installation, effectively solving the problem of inconvenient installation of traditional high-voltage static var generators.

[0037] As a preferred example of this application, the movable seat 7 is symmetrically provided with sliders 10 on both outer walls. The sliders 10 are slidably installed in the slide groove 4, and the movable seat 7 forms a sliding fit with the slide groove 4 through the sliders 10. This arrangement makes the sliding of the movable seat 7 in the slide groove 4 more stable and smooth, ensures the accuracy of position adjustment, and further improves the convenience of installation.

[0038] As a preferred example of this application, an annular limiting groove 12 is provided on the front side of the interior of the movable seat 7, and an annular limiting block 13 is provided on the rear side of the internal thread adjusting knob 9. The annular limiting block 13 is rotatably installed in the annular limiting groove 12. The rotation of the annular limiting block 13 in the annular limiting groove 12 limits the internal thread adjusting knob 9, preventing axial displacement of the internal thread adjusting knob 9 during rotation and ensuring the stability of the fit between the internal thread adjusting knob 9 and the external thread sleeve 8.

[0039] As a preferred example of this application, limit blocks 11 are symmetrically arranged on the upper and lower sides of the inner wall of the movable seat 7, and limit grooves 14 are symmetrically opened on the upper and lower sides of the outer wall of the external threaded sleeve 8, with the limit blocks 11 installed in the limit grooves 14. This arrangement effectively restricts the rotation of the external threaded sleeve 8, allowing it to move only back and forth within the movable seat 7, thus ensuring that the internal thread adjustment knob 9 can smoothly drive the external threaded sleeve 8 to adjust its position when rotated.

[0040] As a preferred example of this application, roller seats 5 are symmetrically arranged on both sides of the bottom of the generator body 1, and several sets of rollers 6 are installed in the roller seats 5. The arrangement of the rollers 6 facilitates the movement of the generator body 1, making it easier and less strenuous to adjust the position of the generator before installation.

[0041] As a preferred example of this application, the number of rollers 6 is three sets, and the three sets of rollers 6 are respectively arranged on the front and rear sides and the middle position inside the roller seat 5. The distribution of the three sets of rollers 6 makes the generator body 1 more stable during movement, reduces shaking, and improves safety during movement.

[0042] As a preferred example of this application, the outer wall of the internal thread adjustment knob 9 is provided with an anti-slip groove, and the groove extends along the axial direction of the internal thread adjustment knob 9. The anti-slip groove increases the friction between the hand and the internal thread adjustment knob 9, making it easier for the operator to rotate the internal thread adjustment knob 9 and preventing slippage during rotation.

[0043] As a preferred example of this application, the length of the support rod 17 is the same as the length of the external threaded sleeve 8. This arrangement ensures that the support rod 17 can better cooperate with the external threaded sleeve 8 during rotation and adjustment, making the adjustment of the limiting plate 15 more precise.

[0044] As a preferred example of this application, the thickness of the annular limiting block 13 is equal to the depth of the annular limiting groove 12. This makes the annular limiting block 13 rotate more smoothly within the annular limiting groove 12, preventing wobbling and further ensuring the stability of the internal thread adjustment knob 9.

[0045] As a preferred example of this application, the length of the limiting block 11 is no greater than the length of the limiting groove 14. This configuration provides sufficient space for the forward and backward movement of the external threaded sleeve 8, ensuring that the external threaded sleeve 8 can be smoothly adjusted in position to meet the needs of different installation scenarios.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
