Description

Technical Field

[0001] This invention relates to the field of electrical grid insulator recycling technology, and in particular to a fixed device. Background Technology

[0002] Electrical grid insulators are insulating devices used in power transmission systems, typically made of ceramic materials. Their primary function is to provide insulation support in transmission lines, preventing current leakage to the ground or other conductors, and ensuring the safe operation of the power system. During use, these insulators need to be collected and stored. However, current methods involve placing the insulators horizontally or vertically in storage devices and manually clamping them. Therefore, current methods are inconvenient, time-consuming, require manual operation, and pose certain risks. Summary of the Invention

[0003] Therefore, it is necessary to provide a fixed device to address the problems of inconvenience, time-consuming operation, and the need for manual operation by workers in the current method of recycling and storing electrical grid porcelain insulators, which poses certain dangers.

[0004] The technical solution is as follows:

[0005] On the one hand, a fixing device is provided, comprising:

[0006] The mounting body is provided with a mounting cavity;

[0007] The inner liner is installed in the mounting cavity and slides vertically with the mounting body. The side wall of the inner liner is provided with a first sliding part and a second sliding part arranged at an angle. From the top of the inner liner to the bottom of the inner liner, the distance between the first sliding part and the second sliding part tends to increase.

[0008] An elastic element, wherein the elastic element is disposed between the bottom of the inner liner and the mounting body; and

[0009] A first clamping member and a second clamping member are both located at least partially inside the inner liner and are spaced apart to form a first clamping space. The first clamping member is slidably engaged with the first sliding part, and the second clamping member is slidably engaged with the second sliding part. Both the first clamping member and the second clamping member are slidably engaged with the mounting body in the horizontal direction, so that the first clamping member and the second clamping member can reciprocate in a direction that moves closer to or further away from each other.

[0010] In the above embodiment, the fixing device is used by passing the porcelain bottle through the first clamping space and placing it in the inner liner. Under the weight of the porcelain bottle, the inner liner descends relative to the mounting body. The elastic element is compressed to store elastic potential energy and buffer the inner liner. Since both the first and second clamping elements slide in a horizontal direction with the mounting body, the first sliding part slides in a sliding engagement with the first clamping element, and the second sliding part slides in a sliding engagement with the second clamping element. This keeps the height of the first and second clamping elements relative to the mounting body constant, and the first and second clamping elements move in a direction that brings them closer to each other to clamp the porcelain bottle inside the inner liner, thus achieving the clamping, fixing, and storage of the porcelain bottle. When the porcelain insulator inside the inner liner is moved upwards, the elastic element releases its elastic potential energy to drive the inner liner to rise relative to the mounting body. Since both the first and second clamping elements slide horizontally with the mounting body, the first clamping element moves relative to the first sliding part to reset, and the second clamping element moves relative to the second sliding part to reset. Thus, the height of the first and second clamping elements relative to the mounting body remains unchanged, and the first and second clamping elements move back to their initial positions in a direction away from each other, facilitating the next storage of porcelain insulators. Compared to current methods of recycling and storing electrical grid porcelain insulators, the fixing device in this application can automatically clamp the first and second clamping elements by using the gravity of the porcelain insulator to move them closer together, and then reset them by using the elastic element to move them further apart. This reduces manual labor and improves the clamping efficiency and safety of the fixing device.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the inner liner includes a bottom plate and four fixed walls. The four fixed walls are correspondingly disposed on the four sides of the bottom plate to form a fixed cavity. Each of the four fixed walls is provided with a first sliding portion and a second sliding portion. There are four first clamping members and four second clamping members. The four first clamping members slide in cooperation with the four first sliding portions, and the four second clamping members slide in cooperation with the four second sliding portions, so that the four first clamping members and the four second clamping members can cooperate in the fixed cavity to form the first clamping space. The four first clamping members and the four second clamping members slide in cooperation with the mounting body in the horizontal direction.

[0013] In one embodiment, each of the four fixed walls is further provided with a third sliding portion and a fourth sliding portion arranged at an angle, from the top of the inner liner toward the bottom of the inner liner. The distance between the third sliding portion and the fourth sliding portion tends to increase. The third sliding portion is arranged vertically below the first sliding portion, and the fourth sliding portion is arranged vertically below the second sliding portion. The fixing device also includes four third clamping members and four fourth clamping members. The four third clamping members slide in cooperation with the four third sliding portions, and the four fourth clamping members slide in cooperation with the four fourth sliding portions, so that the four third clamping members and the four fourth clamping members can cooperate in the fixing cavity to form a second clamping space. The four third clamping members and the four fourth clamping members all slide in cooperation with the mounting body in the horizontal direction.

[0014] In one embodiment, the first sliding part is configured as a first sliding groove, and the second sliding part is configured as a second sliding groove, wherein the first sliding groove and the second sliding groove are symmetrically arranged about the center line of the fixed wall in the vertical direction.

[0015] In one embodiment, the first clamping member includes a fifth sliding portion, a first mounting portion, and a first clamping portion. The fifth sliding portion and the first clamping portion are respectively fixed on opposite sides of the first mounting portion. Both the first mounting portion and the first clamping portion are located within the fixed cavity. The fifth sliding portion passes through the first sliding groove and slides in cooperation with the first sliding groove. The second clamping member includes a sixth sliding portion, a second mounting portion, and a second clamping portion. The sixth sliding portion and the second clamping portion are respectively fixed on opposite sides of the second mounting portion. Both the second mounting portion and the second clamping portion are located within the fixed cavity. The sixth sliding portion passes through the second sliding groove and slides in cooperation with the second sliding groove.

[0016] In one embodiment, the fifth sliding part has a limiting part at one end away from the first mounting part, and the limiting part is used to abut against the outer side of the fixed wall.

[0017] In one embodiment, the first clamping part is configured as a first clamping post, and there are at least two first clamping posts. The second clamping part is configured as a second clamping post, and there are at least two second clamping posts. In the vertical direction, each of the first clamping posts is spaced apart, and each of the second clamping posts is spaced apart. The first clamping posts on the fixed wall and the second clamping posts on the adjacent fixed walls are arranged alternately.

[0018] In one embodiment, the mounting body includes a base and four slide rails, the four slide rails being spaced apart on the base to cooperate in forming the mounting cavity, the inner liner being slidably engaged with the four slide rails, and the elastic element being located between the bottom of the inner liner and the base.

[0019] In one embodiment, the fixing device further includes a guide rod arranged in a horizontal direction. The first clamping member is provided with a first guide hole, and the second clamping member is provided with a second guide hole. The guide rod passes through the first guide hole and the second guide hole and is slidably engaged with both the first guide hole and the second guide hole. The two ends of the guide rod are respectively fixedly connected to the two slide rails on both sides of the first clamping member.

[0020] In one embodiment, when both the first guide hole and the second guide hole are located inside the inner liner, the two opposite sidewalls of the inner liner are provided with vertically arranged clearance holes, and the guide rod passes through the two clearance holes, the first guide hole and the second guide hole respectively.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 4 As shown, in one embodiment, a fixing device 10 is provided, including a mounting body 100, an inner liner 200, an elastic member 300, a first clamping member 400, and a second clamping member 500. The mounting body 100 has a mounting cavity 110. The inner liner 200 is mounted in the mounting cavity 110 and slides vertically with the mounting body 100. The sidewall of the inner liner 200 has a first sliding portion 210 and a second sliding portion 220 arranged at an angle, with the distance between the first sliding portion 210 and the second sliding portion 220 increasing from the top of the inner liner 200 towards the bottom. The elastic member 300 is disposed between the bottom of the inner liner 200 and the mounting body 100. The first clamping member 400 and the second clamping member 500 are both at least partially located inside the inner liner 200 and are spaced apart to form a first clamping space. The first clamping member 400 is slidably engaged with the first sliding part 210, and the second clamping member 500 is slidably engaged with the second sliding part 220. The first clamping member 400 and the second clamping member 500 are both slidably engaged with the mounting body 100 in the horizontal direction, so that the first clamping member 400 and the second clamping member 500 can reciprocate in the direction of approaching or moving away from each other.

[0032] In the above embodiment, the fixing device 10, when in use, passes the porcelain bottle through the first clamping space and places it in the inner liner 200, so that the inner liner 200 descends relative to the mounting body 100 under the weight of the porcelain bottle. The elastic element 300 is compressed to store elastic potential energy and buffer the inner liner 200. Since the first clamping element 400 and the second clamping element 500 are both slidably engaged with the mounting body 100 in the horizontal direction, the first sliding part 210 is slidably engaged with the first clamping element 400, and the second sliding part 220 is slidably engaged with the second clamping element 500. Thus, the height of the first clamping element 400 and the second clamping element 500 relative to the mounting body 100 remains unchanged, and the first clamping element 400 and the second clamping element 500 move in a direction that approaches each other to clamp the porcelain bottle in the inner liner 200, thereby achieving clamping and fixing the porcelain bottle. When the porcelain bottle inside the inner liner 200 is moved upward, the elastic element 300 releases elastic potential energy to drive the inner liner 200 to rise relative to the mounting body 100. Since the first clamping element 400 and the second clamping element 500 are both slidably engaged with the mounting body 100 in the horizontal direction, the first clamping element 400 moves relative to the first sliding part 210 to reset, and the second clamping element 500 moves relative to the second sliding part 220 to reset. Thus, the height of the first clamping element 400 and the second clamping element 500 relative to the mounting body 100 remains unchanged, and the first clamping element 400 and the second clamping element 500 move to their initial positions in a direction away from each other, so as to facilitate the next storage of the porcelain bottle. Compared to the current method of recycling and storing electrical grid insulators, the fixing device 10 in this application can automatically clamp the first clamping member 400 and the second clamping member 500 by moving them closer together through the gravity of the insulator, and reset them by moving them further apart through the elastic member 300. This reduces manual labor and improves the clamping efficiency and safety of the fixing device 10.

[0033] The elastic element 300 can be a telescopic spring, an elastic block, or other elastic structure. The number of elastic elements 300 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the elastic element 300 is set as a spring, and there are four springs. The four springs are correspondingly set at the four corners of the bottom of the inner liner 200, and all four springs can extend and retract in the vertical direction.

[0034] The first clamping member 400 and the second clamping member 500 can both be clamping arms, clamping rods, clamping brackets, or other clamping structures. The number of the first clamping member 400 and the second clamping member 500 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the first clamping member 400 and the second clamping member 500 can cooperate to form a first gripper structure.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, the inner liner 200 further includes a base plate 230 and four fixed walls 240. The four fixed walls 240 are correspondingly disposed on the four sides of the base plate 230 to form a fixed cavity 250. Each of the four fixed walls 240 is provided with a first sliding part 210 and a second sliding part 220. There are four first clamping members 400 and four second clamping members 500. The four first clamping members 400 are slidably engaged with the four first sliding parts 210, and the four second clamping members 500 are slidably engaged with the four second sliding parts 220, so that the four first clamping members 400 and the four second clamping members 500 can cooperate in the fixed cavity 250 to form a first clamping space. The four first clamping members 400 and the four second clamping members 500 are all slidably engaged with the mounting body 100 in the horizontal direction. Thus, the four first clamping members 400 can cooperate with the four second clamping members 500 to form four first gripper structures, so that the four first gripper structures cooperate with each other to clamp the porcelain bottle from four directions outside the porcelain bottle, thereby improving the reliability and stability of the fixing device 10.

[0036] The structures and working principles of the first sliding part 210, the second sliding part 220, the first clamping member 400, and the second clamping member 500 on different fixed walls 240 are the same or similar. The structure and working principle of the second clamping member 500 on the same fixed wall 240 are the same or similar to those of the first clamping member 400, and will not be described in detail here.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, optionally, each of the four fixed walls 240 is further provided with a third sliding portion 260 and a fourth sliding portion 270 arranged at an angle, from the top of the inner liner 200 toward the bottom of the inner liner 200. The distance between the third sliding portion 260 and the fourth sliding portion 270 tends to increase. The third sliding portion 260 is arranged vertically below the first sliding portion 210, and the fourth sliding portion 270 is arranged vertically below the second sliding portion 220. The fixing device 10 also includes four third clamping members 600 and four fourth clamping members 700. The four third clamping members 600 and the four third sliding portions 260 are correspondingly slidably engaged, and the four fourth clamping members 700 and the four fourth sliding portions 270 are correspondingly slidably engaged, so that the four third clamping members 600 and the four fourth clamping members 700 can cooperate in the fixing cavity 250 to form a second clamping space. The four third clamping members 600 and the four fourth clamping members 700 are all correspondingly slidably engaged with the mounting body 100 in the horizontal direction. Thus, the four third clamping members 600 can cooperate with the four fourth clamping members 700 to form four second gripper structures, and the four first gripper structures and the four second gripper structures are arranged at intervals in the vertical direction, so that the four first gripper structures and the four second gripper structures cooperate with each other, thereby making the first clamping space and the second clamping space located at the upper and lower ends of the porcelain bottle respectively, so as to clamp the porcelain bottle from the upper and lower ends, thereby improving the reliability and stability of the fixing device 10.

[0038] Among them, on the same fixed wall 240, the structure and working principle of the third sliding part 260 are the same as or similar to the structure and working principle of the first sliding part 210, the structure and working principle of the fourth sliding part 270 are the same as or similar to the structure and working principle of the second sliding part 220, the structure and working principle of the third clamping member 600 are the same as or similar to the structure and working principle of the first clamping member 400, and the structure and working principle of the fourth clamping member 700 are the same as or similar to the structure and working principle of the second clamping member 500. These will not be described in detail here.

[0039] Both the first sliding part 210 and the second sliding part 220 can be configured as a sliding rail, a sliding groove or other sliding structure.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the first sliding part 210 is configured as a first sliding groove, and the second sliding part 220 is configured as a second sliding groove. The first sliding groove and the second sliding groove are symmetrically arranged about the center line of the fixed wall 240 in the vertical direction. In this way, the first clamping member 400 and the second clamping member 500 can move synchronously in directions that are closer to or further away from each other, thereby improving the reliability and stability of the fixing device 10.

[0041] The angle between the extension direction of the first slide groove and the vertical direction, the extension length of the first slide groove, the angle between the extension direction of the second slide groove and the vertical direction, and the extension length of the second slide groove can all be flexibly adjusted according to the diameter of the porcelain bottle. Specifically, in this embodiment, the angles between the extension direction of the first slide groove and the vertical direction, and the angles between the extension direction of the second slide groove and the vertical direction are both 45°. The vertical lengths of both the first and second slide grooves are 120mm, and the horizontal lengths of both the first and second slide grooves are 120mm. The distance between the top of the first slide groove and the vertical centerline of the fixed wall 240 is 75mm, and the distance between the top of the second slide groove and the vertical centerline of the fixed wall 240 is 75mm. Thus, the fixing device 10 can clamp and fix porcelain bottles with diameters ranging from 150mm to 390mm.

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the first clamping member 400 includes a fifth sliding part 410, a first mounting part 420, and a first clamping part 430. The fifth sliding part 410 and the first clamping part 430 are respectively fixed on opposite sides of the first mounting part 420. The first mounting part 420 and the first clamping part 430 are both located in the fixing cavity 250. The fifth sliding part 410 passes through the first sliding groove and slides in cooperation with the first sliding groove. The second clamping member 500 includes a sixth sliding part, a second mounting part, and a second clamping part. The sixth sliding part and the second clamping part are respectively fixed on opposite sides of the second mounting part. The second mounting part and the second clamping part are both located in the fixing cavity 250. The sixth sliding part passes through the second sliding groove and slides in cooperation with the second sliding groove. Thus, the first clamping part 430 can slide relative to the fixed wall 240 through the first mounting part 420 and the fifth sliding part 410, and the second clamping part can slide relative to the fixed wall 240 through the second mounting part and the sixth sliding part, so that the first clamping part 430 and the second clamping part can move closer to each other to clamp the porcelain bottle, or move away from each other to remove the porcelain bottle.

[0043] The number of the first clamping part 430 and the second clamping part can be flexibly adjusted according to actual usage needs.

[0044] like Figure 4 and Figure 5 As shown, further, the fifth sliding part 410 has a limiting part 440 at the end away from the first mounting part 420. The limiting part 440 is used to abut against the outer side of the fixed wall 240. In this way, the limiting part 440 and the first mounting part 420 can abut against the inner and outer sides of the fixed wall 240 respectively, ensuring that the first clamping member 400 will not fall off the fixed wall 240 during the sliding process, thus improving the reliability of the fixing device 10.

[0045] Optionally, the first clamping part 430 is configured as a first clamping post, with at least two first clamping posts, and the second clamping part is configured as a second clamping post, with at least two second clamping posts. The first clamping posts and second clamping posts are spaced apart vertically, and the first clamping posts on the fixed wall 240 and the second clamping posts on adjacent fixed walls 240 are arranged alternately. Thus, a second clamping post passes between two adjacent first clamping posts, and a first clamping post passes between two adjacent second clamping posts, allowing the first clamping members 400 and second clamping members 500 on adjacent fixed walls 240 to mutually limit each other vertically. This ensures that the height of the first clamping members 400 and second clamping members 500 relative to the mounting body 100 remains constant, and that each first clamping member 400 and each second clamping member 500 can move synchronously in a horizontal direction, improving the reliability of the fixing device 10.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the mounting body 100 includes a base 120 and four slide rails 130. The four slide rails 130 are spaced apart on the base 120 to form a mounting cavity 110. The inner liner 200 is slidably engaged with all four slide rails 130. An elastic element 300 is located between the bottom of the inner liner 200 and the base 120. In this way, the four slide rails 130 can limit the inner liner 200 from four directions, ensuring that the inner liner 200 can move stably and reliably in the vertical direction, thus improving the reliability of the fixing device 10.

[0047] Specifically, in this embodiment, all four slide rails 130 are configured as right-angle bent rails, and a fixed wall 240 is provided between two adjacent right-angle bent rails. The two sides of the fixed wall 240 are in vertical sliding cooperation with the two adjacent right-angle bent rails.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing device 10 further includes a guide rod 140 arranged in the horizontal direction. The first clamping member 400 is provided with a first guide hole 421, and the second clamping member 500 is provided with a second guide hole. The guide rod 140 passes through the first guide hole 421 and the second guide hole, and is slidably engaged with both the first guide hole 421 and the second guide hole. The two ends of the guide rod 140 are respectively fixedly connected to two slide rails 130 on both sides of the first clamping member 400. In this way, the guide rod 140 can play a guiding and limiting role, ensuring that neither the first clamping member 400 nor the second clamping member 500 can move vertically relative to the mounting body 100, and that the first clamping member 400 and the second clamping member 500 can move along the axial direction of the guide rod 140.

[0049] The number of guide rods 140 can be flexibly adjusted according to actual usage needs. Guide rods 140 can be positioned either on the inner or outer side of the fixed wall 240. Specifically, in this embodiment, the number of guide rods 140 is twice the number of fixed walls 240. The number of first guide holes 421 and second guide holes are the same as the number of guide rods 140, and each first guide hole 421 and each second guide hole corresponds to each guide rod 140. The guide rods 140 are located on the inner side of the fixed wall 240, meaning the first guide holes 421 are correspondingly positioned on the first mounting portion 420, and the second guide holes are correspondingly positioned on the second mounting portion.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, optionally, when both the first guide hole 421 and the second guide hole are located inside the inner liner 200, the two opposite sidewalls of the inner liner 200 are provided with vertically oriented clearance holes 241, and the guide rod 140 passes through the two clearance holes 241, the first guide hole 421, and the second guide hole respectively. In this way, the distance between the central axis of the guide rod 140 and the center of gravity of the first clamping member 400, and the distance between the central axis of the guide rod 140 and the center of gravity of the second clamping member 500 are both reduced, ensuring that the first clamping member 400 and the second clamping member 500 can reciprocate stably and reliably in directions of mutual approach or mutual distance, thus improving the reliability of the fixing device 10.

[0051] Specifically, in this embodiment, each fixed wall 240 is provided with four clearance holes 241. The four clearance holes 241 are respectively provided on both sides of the fixed wall 240 parallel to the guide rail, and two clearance holes 241 on each side are respectively provided at the upper and lower ends of the fixed wall 240. Each fixed wall 240 is provided with four guide rods 140, which are arranged vertically, so that two guide rods 140 pass through each clearance hole 241.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.
