Description

Technical Field

[0001] This application relates to the field of power equipment, and more particularly to a support device. Background Technology

[0002] With the increasing proportion of renewable energy generation, the power system is facing challenges such as declining inertia, weakened voltage support capacity, and deteriorating frequency stability. While traditional SVG (Static Var Generator) systems, primarily based on current source control, can quickly compensate for reactive power, they are prone to instability under weak grid conditions and fault scenarios. In contrast, grid-based SVG systems, by simulating the electromechanical transient characteristics of synchronous generators, can actively construct voltage and frequency references for the grid, providing virtual inertia and damping support, achieving zero-delay response and several times the overload output at the moment of a fault.

[0003] Currently, most network-type SVG modules use an integral frame with guide rails for installation. Existing solutions require that after the module is pushed into place, limit blocks be installed at both ends of the guide rail and locked to the module. In the confined environment of a construction site at height, the disassembly and reassembly of the rear limit fastener is difficult. Furthermore, after removing the rear limit fastener between the rear limit block and the module, poor contact between the rear limit block and the module can easily occur, generating a floating potential. This reduces maintenance efficiency and seriously impairs the electrical reliability of the equipment. Summary of the Invention

During the forward movement of the support assembly in the first direction, the locking mechanism can lock with the locking seat to constrain the movement of the support assembly in the first direction. If the support assembly continues to move forward, the locking mechanism disengages from the locking seat, thereby unlocking the support assembly.

Detailed Implementation

[0018] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a support device 100, which includes: a guide rail 1, a support component 2, and a self-locking component 3.

[0020] The support assembly 2 is used to support an item, for example, a mesh-type SVG module (hereinafter referred to as the module). The bottom of the module is fixedly connected to the support assembly 2 by fasteners (such as bolts). The guide rail 1 is mounted on the valve section insulating beam used to support the module. The support assembly 2 is used to support the module and is movably disposed on the guide rail 1 along a first direction. In this embodiment, the first direction is the front-rear direction of the support device 100.

[0021] like Figure 3 As shown, the self-locking assembly 3 includes a locking mechanism 31 and a locking seat 32. The locking mechanism 31 is located at the end of the support assembly 2, for example, at the front end of the support assembly 2. The locking seat 32 is located at the front end of the guide rail 1. When the module is installed, the operator pushes the entire module, along with the bottom support assembly 2, forward into the guide rail 1. When pushed to the predetermined position, the locking mechanism 31 and the locking seat 32 lock together to form a locked state, thereby restricting the support assembly 2 and the module from moving relative to the guide rail 1 in a first direction. When disassembly is required, the support assembly 2 is pushed forward further than the locked position, and the locking mechanism 31 disengages from the locking seat 32, thus unlocking the module.

[0022] In this embodiment, the support device 100 has a self-locking component 3 positioned at the front end of the guide rail 1 and the support component 2. When the module is pushed forward into place, it automatically locks. The support component 2 and the guide rail 1 are connected at the same potential, eliminating the need for additional rear limit fasteners and avoiding the risk of floating potential. Disassembly is simple; just push the module forward a short distance to unlock it, solving the problem of difficult rear limit fastener installation and removal in existing technologies and improving the convenience of on-site maintenance.

[0023] like Figure 4 As shown, in some embodiments, the guide rail 1 includes a first guide rail 1a and a second guide rail 1b that are parallel to each other, both extending along a first direction. Both the first guide rail 1a and the second guide rail 1b include a guide rail body 11 and a baffle 12. Optionally, the guide rail body 11 has a hollow structure. The baffle 12 is disposed on the top of the guide rail body 11, and one side wall of the baffle 12 is flush with one side wall of the guide rail body 11.

[0024] like Figure 2 and Figure 5 As shown, the support component 2 includes at least one support unit 2a, and the support unit 2a includes: a support frame 21, a roller 22, a first limiting flange 23 and a second limiting flange 24.

[0025] The support frame 21 includes a front support beam 211, a left support beam 212, a rear support beam 213, and a right support beam 214 connected end to end. The support frame 21 also includes a middle beam 215, one end of which is connected to the front support beam 211, and the other end to the rear support beam 213. The middle beam 215 is located between the left support beam 212 and the right support beam 214. The support frame 21 can be made of high-strength aluminum alloy profiles.

[0026] Rollers 22 are rotatably mounted on the support frame 21. For example, two rollers 22 are respectively provided on the left support beam 212 and the right support beam 214. The rollers 22 are capable of rolling on the guide rail body 11. Optionally, the rollers 22 are rubber-coated bearing rollers or all-metal needle roller bearing rollers.

[0027] like Figure 6 As shown, the first limiting flange 23 and the second limiting flange 24 are respectively disposed on two opposite side walls of the support frame 21. For example, the first limiting flange 23 is located on the outer side wall of the left support beam 212, and the second limiting flange 24 is located on the outer side wall of the right support beam 214. The first limiting flange 23 can abut against the baffle 12 of the first guide rail 1a, and the second limiting flange 24 can abut against the baffle 12 of the second guide rail 1b. Through the cooperation structure of the limiting flange and the baffle, the left and right displacement of the support component 2 can be effectively restricted during the process of the support frame 21 being pushed into the guide rail 1, thus eliminating left and right offset errors.

[0028] There are two self-locking components 3. The two locking mechanisms 31 are located on both sides of the front end of the support component 2, and the two locking seats 32 are connected to the first guide rail 1a and the second guide rail 1b, respectively.

[0029] In some embodiments, there are multiple support units 2a, which are arranged sequentially along a first direction and adjacent support units 2a are connected to each other. The number of support units 2a can be increased or decreased according to the module length to improve the adaptability of the support assembly 2. The locking mechanism 31 is connected to the foremost support unit 2a.

[0030] like Figure 7 As shown, in some embodiments, the support component further includes an outer connecting block 25 and an inner connecting block 26.

[0031] The outer connecting block 25 is located on the outside of the support frame 21 and connects to two adjacent support frames 21 respectively. The inner connecting block 26 is located on the inside of the support frame 21 and connects to two adjacent support frames 21 respectively. Through this double-sided connection structure, a stable connection is formed between adjacent support units 2a, improving the load-bearing stability of the entire support assembly 2.

[0032] like Figure 5 and Figure 8 As shown, in order to improve the reliability of the connection, a mating structure can also be provided on the contact surface of the adjacent support unit 2a. For example, the two ends of the support frame 21 are respectively provided with a protruding post 216 and a concave hole 217. The protruding post of one support frame 21 can be inserted into the concave hole of the adjacent support frame 21 to improve the reliability of the connection.

[0033] like Figure 4 and Figure 6 As shown, in some embodiments, both the first guide rail 1a and the second guide rail 1b further include a limiting plate 13. The limiting plate 13 is disposed at the top of the baffle 12, with the limiting plate of the first guide rail 1a located above the first limiting flange 23, and the limiting plate of the second guide rail 1b located above the second limiting flange 24. The limiting plate and the limiting flange form a limiting engagement in the vertical direction, preventing the support component 2 from moving in the longitudinal direction, and further improving the structural stability of the module after installation.

[0034] like Figure 9 and Figure 10As shown, in some embodiments, the locking seat 32 is provided with a locking groove 321. Exemplarily, the opening of the locking groove 321 faces the axis of the support device 100 parallel to the first direction. The first end face 322 of the locking seat 32 near the support component 2 and the second end face 323 away from the support component 2 are both inclined surfaces. The first groove wall 324 of the locking groove 321 away from the support component 2 is inclined, the bottom 325 of the locking groove 321 extends parallel to the first direction, and the second groove wall 326 of the locking groove 321 near the support component 2 is approximately perpendicular to the bottom 325. The first end face 322 and the second end face 323 of the locking seat 32 and the first groove wall 324 of the locking groove 321 are all inclined in a direction away from the support component 2.

[0035] The locking mechanism 31 includes a base 311, a slider 312, a first fixing plate 313, a second fixing plate 314, a first elastic element 315, and a second elastic element 316. The base 311 is provided with a groove 3111, which extends along a second direction perpendicular to the first direction. The second direction is the left-right direction of the support device 100. Exemplarily, the groove 3111 is an inverted T-shaped groove. The first fixing plate 313 and the second fixing plate 314 are located on opposite sides of the base 311. Optionally, both the first fixing plate 313 and the second fixing plate 314 may close part of the side opening of the groove 3111.

[0036] The first elastic element 315 is connected at one end to the first fixed plate 313 and at the other end to the slider 312. The second elastic element 316 is connected at one end to the second fixed plate 314 and at the other end to the slider 312. Under the action of elastic force, the slider 312 is in the intermediate position when no external force is applied. Optionally, both the first elastic element 315 and the second elastic element 316 are springs.

[0037] like Figure 11 As shown, during module installation, the support component 2 drives the locking mechanism 31 to move along the guide rail 1 towards the locking seat 32. In the initial state, the slider 312 is in the middle position under the action of the first elastic element 315 and the second elastic element 316, which is the return-to-center state.

[0038] like Figure 11As shown in (a) and (b), when the slider 312 contacts the first end face 322 of the locking seat 32, with the increase of the pushing force, the slider 312 is forced to move along the first end face 322 towards the inside of the support assembly 2. One of the first elastic element 315 and the second elastic element 316 is compressed, and the other elastic element is extended. When the slider 312 passes the highest point of the first end face 322 and enters the area of ​​the locking groove 321, the elastic element releases its elastic force, pushing the slider 312 back to the center, and the slider 312 is locked into the locking groove 321. At this time, if an attempt is made to pull the module backward, the slider 312 will form a rigid abutment with the second groove wall 326 of the locking groove 321, restricting the backward movement of the support assembly 2. If the forward pushing force on the module is less than the preset force, the slider 312 will abut with the first groove wall 324 of the locking groove 321, restricting the forward movement of the support assembly 2, thereby locking the module.

[0039] During unlocking, the forward thrust applied to the module must be greater than the preset force so that the slider 312 overcomes the friction with the first groove wall 324, and the support component 2 continues to move forward. Under the action of the thrust, the slider 312 is forced to move inward along the first groove wall 324, thereby disengaging from the locking groove 321. The module continues to move forward, and the slider 312 disengages from the locking seat 32.

[0040] like Figure 11 As shown in (c), when the module is pulled back, the support component 2 moves backward along the first direction, and the slider 312 abuts against the second end face 323 of the locking seat 32. The second end face 323 guides the slider 312 to slide away from the locking groove 321, that is, to slide outward. During the backward movement of the slider 312, it will not enter the locking groove 321, thus completing the unlocking.

[0041] like Figure 10 As shown, in some embodiments, the locking mechanism 31 further includes a ball 317 located between the slider 312 and the groove wall of the slide 3111. For example, the slider 312 is provided with a ball groove adapted to the ball 317, and the ball 317 partially protrudes from the ball groove to abut against the groove wall of the slide 3111. The ball 317 transforms the sliding friction between the slider 312 and the slide 3111 into rolling friction, significantly reducing the friction force when the slider 312 slides, and making the self-locking component 3 more responsive.

[0042] like Figure 12As shown, the slider 312 includes a sliding portion 3121, a first extension 3122, a second extension 3123, and a locking portion 3124. The sliding portion 3121 is slidably disposed in the slide groove 3111. The first extension 3122 and the second extension 3123 are respectively located on both sides of the sliding portion 3121. The first extension 3122 is connected to the first elastic member 315, and the second extension 3123 is connected to the second elastic member 316. Exemplarily, both the first extension 3122 and the second extension 3123 are provided with a mounting point 3125 for connecting a spring. The bottom end of the slider 312 is generally Z-shaped. The locking portion 3124 is connected to the sliding portion 3121 and is located above the slide groove 3111. The locking portion 3124 can abut against the locking seat 32.

[0043] In some embodiments, the locking part 3124 is cylindrical. The cylindrical locking part 3124 can reduce the frictional resistance when the slider 312 contacts the locking seat 32, making the locking and unlocking process smoother.

[0044] like Figure 13 As shown, in some embodiments, the guide rail 1 further includes a mounting plate 14. For example, the mounting plate 14 is disposed on top of the baffle 12, located at the front end of the guide rail 1. The locking seat 32 is disposed at the bottom of the mounting plate 14. The mounting plate 14 is provided with a clearance groove 15. When unlocking, the support component 2 needs to move forward a certain distance. The clearance groove 15 provides sufficient clearance space for the support component 2, ensuring that the unlocking action is smooth and without interference.

The descriptions of the embodiments above are only for the purpose of helping to understand the technical solutions and core ideas of this application. Therefore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application.
