Description

Technical Field

[0001] The present application relates to the technical field of power systems, and more specifically, to an insulator assembly, a valve tower, a power transmission system, and an energy storage system. Background Art

[0002] Valve tower is the core equipment in the power system, especially in the transmission system and energy storage system.

[0003] The valve tower usually includes a plurality of submodules stacked up and down, and the submodules include a supporting structure and electrical equipment installed in the supporting structure. An insulating structure is installed between adjacent submodules, and the insulating structure and the supporting structure of the submodule are usually connected by flanges and bolts. During the installation of the submodules, the insulating structure is installed on the supporting structure of one submodule, the flange is installed on the supporting structure of another submodule, and the positioning pins are inserted into the holes for inserting bolts in the insulating structure, and the positioning pins are inserted into the holes for inserting bolts in the flange, so as to position the insulating structure and the flange. However, due to the heavy weight of the submodules, during the positioning process, the squeezing of the positioning pins by the submodules on both sides can easily cause the positioning pins to deform, making it difficult to position.

[0004] In summary, the current valve tower has the problem of difficulty in positioning the insulation structure and the supporting structure of the submodule. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide an insulator assembly, a valve tower, a power transmission system and an energy storage system, aiming to solve the technical problem in the prior art that it is difficult to position the insulation structure of the valve tower and the supporting structure of the submodule during the assembly process.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] In a first aspect, an insulator assembly is provided, comprising:

[0008] An insulating structure, wherein one end of the insulating structure along the first direction is a first end, the first end is provided with a first convex portion protruding along the first direction, and a first locking hole is provided on the outer periphery of the first convex portion;

[0009] The first connecting structure has a first matching hole matched with the first protrusion, and a second locking hole opposite to the first locking hole;

[0010] The first locking structure is used to penetrate the first locking hole and the second locking hole which are arranged opposite to each other so as to connect the first end with the first connecting structure.

[0011] Compared with the prior art, the insulator assembly provided by the embodiment of the present application has at least the following technical effects:

[0012] In the insulator assembly provided in the present embodiment, the first connecting structure is connected to the supporting structure of the submodule in the valve tower, and the insulating structure is connected to the first connecting structure, thereby connecting the insulating structure to the supporting structure. The insulator assembly provided in the embodiment of the present application can be installed between the supporting structures of two adjacent submodules. In the process of connecting the insulating structure to the two adjacent supporting structures, the first connecting structure is installed on the supporting structure of one of the submodules, and the insulating structure is installed on the supporting structure of the other submodule. In the positioning process, positioning can be performed only by the first protrusion, or by the first protrusion cooperating with the positioning pin. When positioning is performed only by the first protrusion, the first protrusion extends into the first matching hole, and the cooperation between the first protrusion and the first matching hole enables a certain degree of positioning between the insulating structure and the first connecting structure. When positioning is performed by cooperating with the first protrusion and the positioning pin, the positioning pin is inserted into one of the first locking holes, so that the first protrusion extends into the first matching hole and the positioning pin extends into the second locking hole, thereby completing the positioning process of the first connection structure and the insulating structure, and pulling out the positioning pin, passing the first locking structure through the first locking hole and the second locking hole, so as to connect the insulating structure and the first connection structure, thereby connecting the insulating structure to the supporting structure. When positioning is performed only by the first protrusion, there is no need to use the positioning pin, so damage to the positioning pin can be avoided. Since the first protrusion is protrudingly arranged at the first end, the structural connection strength between the first protrusion and the first end is relatively strong, and the first protrusion will not shake relative to the first end, so that positioning is convenient and not easy to deform; when positioning is performed by the first protrusion and the positioning pin, since the first protrusion and the positioning pin can share the extrusion force, the extrusion force can be shared by the first protrusion and the positioning pin, so that the first protrusion and the positioning pin are not easy to deform, so that the submodule and the insulating structure are easy to assemble.

[0013] In a possible design, in a cross section perpendicular to the first direction, a maximum area of ​​the first protrusion is larger than an area of ​​a region surrounded by a hole wall of the first locking hole.

[0014] In this arrangement, since the maximum area of ​​the first protrusion is larger than the area of ​​the area enclosed by the hole wall of the first locking hole in the cross section perpendicular to the first direction, the first protrusion is thicker than the positioning pin, so that the first protrusion has a greater structural strength than the positioning pin and is less likely to deform during the positioning of the upper and lower sub-modules, thereby facilitating the assembly of the sub-modules and the insulation structure.

[0015] In a possible design, a second protrusion is further provided on the first end along the first direction, and the first connecting structure has a second matching hole matched with the second protrusion.

[0016] In this arrangement, the insulating structure and the supporting structure can be positioned by the cooperation between the first protrusion and the second protrusion without the use of positioning pins, thereby eliminating the step of removing the positioning pins after the alignment is completed, thereby improving the assembly efficiency of the insulating structure and the supporting structure.

[0017] In a possible design, in the first direction, the length of the first protrusion is greater than or equal to the length of the second protrusion.

[0018] In this arrangement, when the length of the first convex portion is equal to that of the second convex portion, the first convex portion and the second convex portion are respectively in contact with the first connection structure, and the first convex portion and the second convex portion jointly bear the extrusion force, so that the first convex portion and the second convex portion respectively bear a relatively smaller extrusion force. When the length of the first convex portion is greater than the length of the second convex portion, the first convex portion bears the extrusion force first. Since the first convex portion shares the extrusion force for the second convex portion, it plays a certain protective role for the second convex portion, and reduces the possibility of deformation of the second convex portion to a certain extent.

[0019] In a possible design, the maximum outer diameter of the second protrusion is greater than the minimum inner diameter of the first locking hole.

[0020] In this arrangement, the second protrusion is relatively thicker and has a stronger structural strength.

[0021] In a possible design, in the first direction, the length of the first protrusion is greater than the length of the second protrusion, and the maximum outer diameter of the second protrusion is smaller than the maximum outer diameter of the first protrusion.

[0022] In this arrangement, the second protrusion is smaller in size, occupies less space, and is lighter in weight.

[0023] In a possible design, the first protrusion includes a first guide segment, and in a cross section perpendicular to the first direction, a cross-sectional area of ​​the first guide segment gradually decreases from a side close to the first end to a side away from the first end.

[0024] In this arrangement, the arrangement of the first guide section facilitates the first protrusion to extend into the first matching hole.

[0025] In a possible design, the first protrusion includes a first limiting section, the first limiting section is connected between the first guide section and the first end, and the first limiting section is an equal-diameter columnar structure extending along the first direction.

[0026] In this arrangement, the setting of the first limiting section can increase the contact area between the first protrusion and the inner wall of the first matching hole, reduce the shaking of the first protrusion relative to the first matching hole to a certain extent, and improve the stability of the first protrusion inserted in the first matching hole.

[0027] In a possible design, the first matching hole is a circular hole, the first guide section and the first limiting section are respectively coaxially arranged with the first end, the first guide section includes a truncated cone structure, and the first limiting section includes a cylindrical structure.

[0028] In this arrangement, the circumference of the truncated cone structure and the cylindrical structure does not include edges, so during the alignment process, there will be no direct contact and relative friction between the edges and the inner wall of the circular hole, which can reduce the wear of the first protrusion during the alignment process.

[0029] In a possible design, the second protrusion includes a second guide segment, and in a cross section perpendicular to the first direction, a cross-sectional area of ​​the second guide segment gradually decreases from a side close to the first end to a side away from the first end.

[0030] In this arrangement, the second guide section is arranged to facilitate the second protrusion to extend into the second matching hole.

[0031] In a possible design, the second protrusion includes a second limiting section, the second limiting section is connected between the second guide section and the first end, and the second limiting section is an equal-diameter columnar structure extending along the first direction.

[0032] In this arrangement, the second limiting section can increase the contact area between the second protrusion and the inner wall of the second matching hole, reduce the shaking of the second protrusion relative to the second matching hole to a certain extent, and improve the stability of the second protrusion inserted in the second matching hole.

[0033] In one possible design, the other end of the insulating structure along the first direction has a second end, the second end is provided with a third protrusion protruding along the first direction, and the second end is also provided with a third locking hole; the insulator assembly also includes a second connecting structure and a second locking structure, the second connecting structure has a third matching hole arranged to cooperate with the third protrusion, and a fourth locking hole arranged opposite to the third locking hole, and the second locking structure is used to pass through the relatively arranged third locking hole and fourth locking hole to connect the second end to the second connecting structure.

[0034] In this setting, the second connecting structure is used to connect to the supporting structure of the submodule located above, the insulating structure is positioned with the second connecting structure through the third protrusion, and the insulating structure is connected to the second connecting structure through the second locking structure through the third locking hole and the fourth locking hole, so as to realize the connection between the insulating structure and the supporting structure of the submodule located above.

[0035] In a possible design, the second end is further provided with a fourth protrusion, and the second connecting structure is provided with a fourth matching hole matched with the fourth protrusion.

[0036] In this arrangement, the third protrusion cooperates with the fourth protrusion to achieve positioning between the insulating structure and the supporting structure, thereby improving positioning efficiency.

[0037] The third protrusion is coaxially arranged with the second end.

[0038] In this arrangement, the third protrusion is coaxially arranged with the second end, that is, the third protrusion is arranged in the middle area of ​​the second end, so that the second end and the second connecting structure can be coaxially positioned during the positioning process by the cooperation of the third protrusion with the third matching hole.

[0039] In a possible design, a first protrusion is provided at the first end, a third protrusion is provided at the second end, and the first protrusion is coaxially arranged with the third protrusion.

[0040] In this arrangement, the first end is positioned with the support structure located below through the first protrusion, and the second end is positioned with the support structure located above through the third protrusion, and positioning with the upper and lower support structures can be achieved through a small number of protrusions. The coaxial arrangement of the first protrusion and the third protrusion facilitates the production of the insulating structure.

[0041] In one possible design, the other end of the insulating structure along the first direction has a second end, the first end is provided with a first protrusion and a second protrusion, the second end is provided with two fourth protrusions protruding along the first direction, the distance between each fourth protrusion and the axis of the second end is equal, and the second end is also provided with a third locking hole; the insulator assembly also includes a second connecting structure and a second locking structure, the second connecting structure has a fourth matching hole arranged to cooperate with the fourth protrusion, and a fourth locking hole arranged opposite to the third locking hole, and the second locking structure is used to penetrate the third locking hole and the fourth locking hole arranged opposite to each other to connect the second end with the second connecting structure.

[0042] In this arrangement, the first end of the insulating structure is positioned with the supporting structure by the cooperation of a first protrusion and a second protrusion, and the second end of the insulating structure is positioned with another supporting structure by the cooperation of two fourth protrusions. The number of protrusions is small, which facilitates the positioning and installation between the insulating structure and the supporting structure. The protrusion structures arranged at the first end and the second end are different, which facilitates the distinction between the first end and the second end, and can play a fool-proof role.

[0043] In a possible design, the number of the second matching holes is greater than the number of the second protrusions.

[0044] In this arrangement, when the first connecting structure is installed on the supporting structure, it is only necessary to adjust the installation position of the first connecting structure by a small rotation so that a second protrusion can be arranged relative to one of the second matching holes on the first connecting structure, thereby facilitating the improvement of the installation efficiency of the first connecting structure on the supporting structure.

[0045] In a second aspect, a valve tower is provided, comprising: a plurality of support structures and a plurality of insulator assemblies as provided by any of the above technical solutions, wherein the plurality of support structures are connected in sequence along a first direction, and two adjacent support structures are connected via a plurality of insulator assemblies.

[0046] In the valve tower provided in this embodiment, since the valve tower includes the insulator assembly provided by any of the above technical solutions, the valve tower at least has all the technical effects of the above insulator assembly, which will not be repeated here.

[0047] In one possible design, an insulator assembly is mounted on the bottom of the bottommost support structure.

[0048] In this arrangement, the assembly process of the insulator assembly and the bottommost support structure is to first fix the first connection structure to the bottom of the support structure, and then connect the insulating structure to the first connection structure. Since the first connection structure is provided with a first protrusion and the first matching hole, the first connection structure and the insulating structure are conveniently positioned by the matching of the first protrusion and the first matching hole, thereby facilitating the assembly of the insulator assembly and the support structure.

[0049] In a third aspect, a power transmission system is provided, comprising the above-mentioned valve tower.

[0050] Since the power transmission system includes the valve tower provided by any of the above-mentioned technical solutions, the power transmission system at least has all the technical effects of the above-mentioned insulator assembly, which will not be repeated here.

[0051] In a fourth aspect, an energy storage system is provided, comprising the valve tower described above, wherein the valve tower carries a power module and a battery module.

[0052] Since the energy storage system includes the above-mentioned valve tower, the energy storage system at least has all the technical effects of the above-mentioned insulator assembly, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0085] In the description of the embodiments of the present application, the term "plurality" refers to more than two (including two).

[0086] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0087] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the insulator assembly or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0088] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0089] The valve tower is a core device in the power system, especially in the power transmission system and the energy storage system. The energy storage system includes a valve tower for realizing the energy storage function. The valve tower includes a submodule, and the submodule includes a supporting structure. A large number of energy storage devices are installed in the supporting structure, which results in a heavy weight of the submodule. In the process of assembling the energy storage valve tower, the bottom submodule is first fixed to the ground, and then an insulator is installed on a submodule, and a flange is installed on the submodule fixed to the ground. A positioning pin is inserted into the bolt hole at one end of the insulator, and the positioning pin is inserted into the bolt hole of the flange to realize the positioning of the insulator and the flange. After the positioning is completed, the positioning pin is pulled out, and then a bolt is inserted into the bolt hole. The flange and the insulator are fixed by the cooperation of the bolt and the nut, so that the insulator is connected between the upper and lower submodules. However, on the one hand, since the locating pin needs to be smoothly inserted into the bolt hole, the outer diameter of the locating pin must be smaller than the inner diameter of the bolt hole of the insulator, and the locating pin is very likely to shake in the bolt hole, especially after one end of the locating pin contacts the surface of the flange, the friction between the locating pin and the end and the surface of the flange can easily cause the locating pin to swing relative to the insulator, making it difficult to insert the locating pin into the bolt hole of the flange. On the other hand, due to the heavy weight of the submodule, it is difficult to accurately align the locating pin with the bolt hole on the flange during hoisting, and the position of the submodule needs to be adjusted laterally. During the adjustment process, it is very easy for the locating pin to be squeezed, deformed or even broken between the two submodules, making it impossible to position. If the structural strength of the locating pin is to be improved, a thicker locating pin needs to be used, but since the locating pin needs to be inserted into the bolt hole, the size of the bolt hole needs to match the size of the bolt, so the adjustment range of the bolt hole size is very small, which also makes it impossible to use a thicker locating pin to improve the structural strength of the locating pin. Therefore, during the hoisting process of the submodule, there is a problem of difficulty in aligning the insulator on the hoisted submodule and the flange in the submodule located on the lower side.

[0090] Based on the above considerations, in order to solve the above problems, an insulator assembly, valve tower, power transmission system and energy storage system are designed. The insulator assembly, valve tower, power transmission system and energy storage system provided in the embodiments of the present application are explained in detail below.

[0091] The insulator assembly disclosed in the embodiment of the present application can be used for a valve tower, and the valve tower can be applied to a power system, such as a power transmission system or an energy storage system, wherein the power transmission system also includes a power transmission valve tower, and the power transmission valve tower carries power equipment, and the power equipment includes a power module. The power transmission valve tower can specifically be a converter valve tower, such as a flexible direct current transmission converter valve tower. The energy storage system also includes an energy storage valve tower, and the energy storage valve tower includes at least one submodule, and a submodule includes a support structure and a power equipment installed on the support structure, and the power equipment includes a power module and a battery module. The battery module may include an electrical cabinet, and a device with an energy storage function such as a battery may be installed in the electrical cabinet. Since the battery module in the submodule usually includes a large number of batteries, the weight of the submodule is large. When the energy storage valve tower includes a plurality of submodules, the plurality of submodules are stacked in sequence in the vertical direction (or in the up and down direction), and insulators are connected between adjacent submodules.

[0092] For the convenience of description, the following embodiments are described by taking an example in which a valve tower according to an embodiment of the present application is applied to an energy storage system, and the valve tower is an energy storage valve tower.

[0093] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the valve tower 1 from an inclined upward angle. Figure 2 It is a front view of the valve tower 1. The valve tower 1 includes a plurality of submodules, and the plurality of submodules are stacked in sequence along the vertical direction (AA direction). The submodule includes a support structure 20, and an electrical device 30 is installed in the support structure 20. The valve tower 1 also includes a plurality of insulator assemblies 10. A plurality of insulator assemblies 10, referred to as bottom insulators 11, are arranged at the bottom of the support structure 20 located at the bottom. The support structure 20 located at the bottom is supported and fixed to the ground by the plurality of bottom insulators 11. A plurality of insulator assemblies 10, referred to as interlayer insulators 12, are arranged between two adjacent support structures 20 above and below. Two adjacent support structures 20 are connected by a plurality of interlayer insulators 12.

[0094] The support structure 20 is used to form a housing space for the power equipment 30, and the support structure 20 may be a frame structure. Figure 1 In the embodiment, the support structure 20 includes cross beams, longitudinal beams and columns, which are connected to form a rectangular frame structure. The rectangular frame structure is enclosed inside to form a receiving space. At least one power device 30 is installed in the receiving space. The power device 30 includes a power module and a battery module. The battery module may include an electric cabinet, and batteries are installed in the electric cabinet. Figure 1 In the embodiment, a plurality of electrical devices 30 are installed in a support structure 20 .

[0095] The insulator assembly 10 provided in this embodiment is at least connected to the support structure 20 as an interlayer insulator 12, that is, in a valve tower 1, the interlayer insulator 12 adopts the insulator assembly 10 provided in this embodiment, and the bottom insulator 11 adopts the insulation structure 100 in the related art. In addition, the insulator assembly 10 provided in this embodiment can also be connected to the support structure 20 as a bottom insulator 11, that is, in another valve tower 1, the interlayer insulator 12 and the bottom insulator 11 adopt the insulator assembly 10 provided in this embodiment.

[0096] When the insulator assembly 10 provided in this embodiment is connected to the support structure 20 as the bottom insulator 11, in the valve tower 1, there are multiple support structures 20, and the multiple support structures 20 are connected in sequence. The insulator assembly 10 provided in this embodiment is installed at the bottom of the bottommost support structure 20. Figure 1 and Figure 2 In the valve tower 1 shown, a plurality of bottom insulators 11 are distributed in an array, and a total of 12 bottom insulators 11 are provided.

The insulator assembly 10 provided in this embodiment is installed between two adjacent support structures 20. Figure 1 and Figure 2 In the valve tower 1 shown, a plurality of interlayer insulators 12 are distributed in an array, and twelve interlayer insulators 12 are respectively arranged between two adjacent support structures 20 .

[0098] Please refer to 3, the insulator assembly 10 provided in this embodiment includes: an insulating structure 100, a first connecting structure 200 and a first locking structure 300. Figure 4 As shown, the insulation structure 100 has a first end 110 at one end along the first direction, and the first end 110 is provided with a first convex portion 111 protruding along the first direction, and a first locking hole 113 is provided on the periphery of the first convex portion 111. Figure 5 As shown, the first connection structure 200 has a first matching hole 210 that is mutually matched with the first protrusion 111, and a second locking hole 230 that is arranged opposite to the first locking hole 113. Figure 3 As shown, the insulating structure 100 and the first connecting structure 200 are connected via a first locking structure 300. The first locking structure 300 is used to penetrate the first locking hole 113 and the second locking hole 230 which are arranged opposite to each other, so as to connect the first end 110 with the first connecting structure 200.

[0099] The insulating structure 100 may be an insulator, which is an insulating control used to form good insulation between the power equipment 30 or other conductors installed in the valve tower 1 and the ground. The insulator includes an insulating part and a fixing part. The insulating part may be made of ceramic, glass or composite insulating material, and the fixing part may be made of insulating material or metal material. The insulating part and the fixing part are fixedly connected, such as glued, and the fixing part is used to fix the insulator to other structures. In addition, the insulating structure 100 may also be other structures that play an insulating role. The insulating structure 100 has a first end 110 and a second end 120 in the first direction, respectively. The fixing part of the insulating structure 100 includes a first end 110, and the first end 110 is used to be connected to the first connection structure 200. The first end 110 is protrudingly provided with a first convex part 111, that is, the first convex part 111 is arranged on the end face of the first end 110 and protrudes from the end face of the first end 110. Specifically, the first convex part 111 protrudes from the side surface of the first end 110 away from the second end 120.

[0100] The first protrusion 111 can be arranged in the middle of the end surface of the first end 110, that is, the central axis of the insulating structure 100 along the first direction is collinear with the central axis of the first protrusion 111 along the first direction, or in other words, the first protrusion 111 is coaxially arranged with the insulating structure 100. If the end surface of the first end 110 is a circular surface, the first protrusion 111 is arranged at the center of the end surface and in the area around the center of the circle. In this arrangement, the first connection structure 200 and the insulating structure 100 can be aligned by the cooperation of the first protrusion 111 and the first matching hole 210. That is, it is convenient to position the first connection structure 200 and the insulating structure 100 at a coaxial arrangement. Of course, in other arrangements, the first protrusion 111 can also be arranged in an area relatively deviated from the middle of the end surface of the first end 110, that is, there is a certain distance between the central axis of the insulating structure 100 along the first direction and the central axis of the first protrusion 111 along the first direction, and they are not collinear.

[0101] The first convex portion 111 is provided with a first locking hole 113 on its periphery, and the first locking hole 113 is used for the first locking structure 300 to pass through. The first locking hole 113 is a through hole. There are multiple first locking holes 113, and the multiple first locking holes 113 are arranged at intervals on the periphery of the first convex portion 111. Exemplarily, the distances between each first locking hole 113 and the first convex portion 111 are equal, and the multiple first locking holes 113 are arranged on the periphery of the first convex portion 111 to form a circular area. Of course, in other arrangements, the multiple first locking holes 113 can be arranged on the periphery of the first convex portion 111 to form a triangle, trapezoid, rectangle, ellipse or other shapes.

[0102] The first connection structure 200 is used to connect with an external structure, which may be a ground, a table, or a support structure 20. Taking the connection between the first connection structure 200 and the support structure 20 as an example, the first connection structure 200 and the support structure 20 may be fixedly connected by welding or the like. The first connection structure 200 and the first end 110 of the insulating structure 100 are connected via the first locking structure 300, and the first end 110 of the insulating structure 100 is connected to the support structure 20 via the first connection structure 200. The first connection structure 200 may be made of a metal material or an insulating material.

[0103] The first matching hole 210 on the first connection structure 200 is arranged at a position opposite to the first protrusion 111 on the first end 110, so that when the first end 110 is connected to the first connection structure 200, the first protrusion 111 at least partially extends into the first matching hole 210. The first matching hole 210 and the first protrusion 111 are arranged in cooperation with each other, which means that the cross-sectional shape of the first matching hole 210 is the same as the cross-sectional shape of the first protrusion 111, the inner diameter of the first matching hole 210 is the same as or similar to the outer diameter of the first protrusion 111, so that the first protrusion 111 can extend into the first matching hole 210, and the inner wall of the first matching hole 210 has a certain degree of limiting effect on the first protrusion 111, so as to limit the movement of the first protrusion 111 in the radial direction. The number of the second locking holes 230 on the first connection structure 200 is equal to the number of the first locking holes 113, and the setting positions are opposite, that is, the first locking holes 113 and the second locking holes 230 are arranged one-to-one. The diameter of the first locking hole 113 is equal to the diameter of the second locking hole 230 .

[0104] The first locking structure 300 is used to connect the insulating structure 100 with the first connecting structure 200, and the first locking structure 300 passes through the first locking hole 113 and the second locking hole 230. The first locking structure 300 can be a structure such as a bolt, a bolt and a nut assembly. Exemplarily, the first locking structure 300 includes a bolt and a nut. Exemplarily, the nut of the bolt abuts against the end of the first end 110 away from the first connecting structure 200, and the screw of the bolt passes through the first locking hole 113 and the second locking hole 230 in sequence, and a part of the screw protrudes from the second locking hole 230. The nut is screwed on the part of the screw protruding from the second locking hole 230, and the nut and the nut clamp the first end 110 of the insulating structure 100 and the first connecting structure 200 from both sides, thereby fixing the insulating structure 100 to the first connecting structure 200. The first locking hole 113 and the second locking hole 230 can both be light holes.

[0105] The first direction is the central axis direction of the insulation structure 100. When the insulation structure 100 is installed in the valve tower 1, the first direction is the vertical direction. In other words, when the insulation structure 100 is in use, the first direction is the vertical direction. Figures 1 to 4 The direction indicated by the arrow AA in is the first direction. The two ends of the insulating structure 100 along the first direction are respectively used to realize the installation of the insulator assembly 10 and the external structure, which can be the ground, the table top, or the support structure 20. When the insulating structure 100 is used as the bottom insulator 11, one end of the two ends of the insulating structure 100 is connected to the ground or the table top, and the other end is connected to the support structure 20. The first end 110 can be the end connected to the ground or the table top, or the end connected to the support structure 20. When the insulating structure 100 is used as the interlayer insulator 12, the two ends of the insulating structure 100 are respectively connected to the two support structures 20, and the first end 110 can be any one of the two ends.

[0106] For example, the assembly process of the valve tower 1 using the insulating structure 100 as the interlayer insulator 12 can be referred to as follows: Figure 6 As shown, the bottom support structure 20 is fixed to the ground through the bottom insulator installed at the bottom. In the process of installing a support structure 20 above the bottom support structure 20, the first connection structure 200 is installed on the top of the bottom support structure 20, and the insulating structure 100 is installed at the bottom of the support structure 20 to be installed. The first end 110 of the insulating structure 100 is the bottom end, that is, the first protrusion 111 is located at the end of the insulating structure 100 away from the support structure 20 connected thereto. Figure 6 As shown, the support structure 20 to be installed is hoisted and moved to the top of the bottom support structure 20, and the insulating structure 100 and the first connecting structure 200 are arranged one by one, and the support structure 20 to be installed is moved downward so that the first protrusion 111 of the insulating structure 100 extends into the first matching hole 210 of the opposite first connecting structure 200, so that the insulating structure 100 and the first connecting structure 200 are positioned to a certain extent. In the positioning process of the insulating structure 100 and the first connecting structure 200, the positioning can be performed only by the matching of the first protrusion 111 and the first matching hole 210, as shown in FIG. Figure 6 and Figure 7As shown, the positioning pin 40 can also be used for auxiliary positioning. In the process of positioning with the help of the positioning pin 40, the first protrusion 111 of the insulating structure 100 can be extended into the first matching hole 210 of the first connecting structure 200, and the positioning pin 40 can be inserted into any one of the first locking holes 113 of the first end 110. When positioning is performed only by the first protrusion 111, since there is no need to use the positioning pin, damage to the positioning pin can be avoided, and since the first protrusion 111 is protrudingly arranged at the first end 110, the structural connection strength between the first protrusion 111 and the first end 110 is relatively strong, that is, the first protrusion 111 will not shake relative to the first end 110, so that positioning is convenient and not easy to deform. When positioning is performed together by the first protrusion 111 and the positioning pin 40, since the first protrusion 111 and the positioning pin 40 can share the extrusion force, the extrusion force on each of the first protrusion 111 and the positioning pin 40 is relatively smaller, and both are not easy to deform.

[0107] In some embodiments, the first protrusion 111 and the first end 110 of the insulating structure 100 may be an integral structure, or a detachable structure and fixedly connected. Exemplarily, the first protrusion 111 and the first end 110 of the insulating structure 100 may be an integral structure manufactured by an integral molding process, or the first protrusion 111 and the first end 110 of the insulating structure 100 may be manufactured separately during the manufacturing process, and during the assembly process, the first protrusion 111 is fixedly connected to the first end 110 of the insulating structure 100, and the first protrusion 111 and the first end 110 of the insulating structure 100 may be connected by bonding, welding, or the like. The first protrusion 111 may be made of a material having a stronger structural strength than the locating pin 40, so that the first protrusion 111 has a stronger structural strength than the locating pin 40 and is less prone to deformation. The first protrusion 111 and the first end 110 of the insulating structure 100 may be made of the same material or different materials. Exemplarily, the first protrusion 111 and the first end 110 of the insulation structure 100 are an integral structure made of the same material, and the structural strength of the first protrusion 111 is greater than the structural strength of the positioning pin 40 .

[0108] In other embodiments, the first protrusion 111 may have a greater structural strength by setting the structural dimensions of the first protrusion 111. Figure 8As shown, in some embodiments, in a cross section perpendicular to the first direction, the maximum area of ​​the first convex portion 111 is greater than the area of ​​the area surrounded by the hole wall of the first locking hole 113. When the first direction is a vertical direction, the direction perpendicular to the first direction is a horizontal direction. In a cross section in the horizontal direction, that is, in a cross section of the insulating structure 100, the maximum area of ​​the cross section of the first convex portion 111 is greater than the area of ​​the area surrounded by the hole wall of the first locking hole 113. If the cross section of the first convex portion 111 is circular, and the area surrounded by the hole wall of the first locking hole 113 is circular, the outer diameter of the first convex portion 111 is greater than the inner diameter of the first locking hole 113. In this way, the outer diameter of the positioning pin 40 or bolt that can be inserted into the first locking hole 113 is smaller than the outer diameter of the first convex portion 111, that is, the first convex portion 111 is thicker, and the structural strength of the first convex portion 111 is greater than the positioning strength of the positioning pin 40 or bolt that can be inserted into the first locking hole 113.

[0109] The maximum cross-sectional area of ​​the first convex portion 111 is the largest cross-sectional area of ​​the first convex portion 111 in all cross-sectional areas perpendicular to the first direction. The first convex portion 111 may be a cylindrical equal-diameter structure, that is, along the first direction, the outer diameters of various regions of the first convex portion 111 are equal and are greater than the inner diameter of the first locking hole 113, then the cross-sectional areas of various regions of the first convex portion 111 are equal, and this area is the maximum cross-sectional area of ​​the first convex portion 111. The first convex portion 111 may be a variable-diameter structure, that is, along the first direction, the outer diameters of some regions of the first convex portion 111 are relatively large, and the outer diameters of other regions are relatively small, and the maximum cross-sectional area of ​​the first convex portion is the cross-sectional area of ​​the first convex portion at the location where the outer diameter is the largest.

[0110] It is worth noting that, since the outer diameter of the first protrusion 111 is larger than the inner diameter of the first locking hole 113, the inner diameter of the first matching hole 210 is larger than the inner diameter of the first locking hole 113, and the inner diameter of the first matching hole 210 is larger than the inner diameter of the second locking hole 230. In this arrangement, it is suitable to use a flange as the first connection structure 200, a large hole with a larger inner diameter is provided in the middle of the flange, and a plurality of small holes with a smaller inner diameter for connection are provided on the periphery of the large hole. That is to say, the flange in the related art can be used as the first connection structure 200, and a first protrusion 111 with a matching size is provided at the first end 110 of the insulating structure 100 according to the size of the large hole of the flange, and a first locking hole 113 with a matching size is provided at the first end 110 according to the size of the small hole of the flange, and the small hole of the flange is used as the second locking hole 230, and the large hole of the flange is used as the second locking hole 230. By using a flange as the first connection structure 200 , there is no need to separately open a mold to manufacture the first connection structure 200 , and the production cost is lower.

[0111] When the first protrusion 111 has a relatively strong structural strength due to the material or structural dimensions of the first protrusion 111, and the structural strength of the first protrusion 111 is greater than the structural strength of the positioning pin 40, in the process of positioning by the cooperation between the first protrusion 111 and the positioning pin 40, the positioning pin 40 of a suitable length can be selected so that the length of the end surface of the positioning pin 40 extending from the first end 110 is less than the length of the end surface of the first protrusion 111 extending from the first end 110. In this way, in the process of positioning the insulating structure 100 and the first connecting structure 200, the first protrusion 111 contacts the first connecting structure 200 before the positioning pin 40. Even if the insulating structure 100 is squeezed during the alignment of the two adjacent supporting structures 20, the first protrusion 111 will bear a relatively greater squeezing force because it is more protruding from the first end 110 than the positioning pin 40, and the first protrusion 111 has a stronger structural strength and is not easily deformed by compression. The first protrusion 111 plays a certain protective role for the positioning pin 40, thereby reducing the influence on the positioning operation caused by the easy deformation of the positioning pin 40. The first protrusion 111 and the positioning pin 40 can achieve two-point positioning for the insulating structure 100 and the first connecting structure 200, that is, the positioning effect is better. When the first protrusion 111 extends into the first matching hole 210, and the positioning pin 40 extends into the second locking hole 230, the positioning of the insulating structure 100 and the first connecting structure 200 is completed. Take out the positioning pin 40, and insert the first locking structure 300 into the first locking hole 113 and the second locking hole 230 to connect the insulating structure 100 and the first connecting structure 200. Thereby, the insulating structure 100 is connected to the bottom support structure 20 and another support structure 20 respectively. In this way, another supporting structure 20 can be installed above the supporting structure 20 located above the bottom layer. The installation process is similar to installing another supporting structure 20 on the bottom layer supporting structure 20, that is, installing the first connecting structure 200 on the supporting structure 20 located below, and installing the insulating structure 100 on the supporting structure 20 to be installed, so that the first end 110 of the insulating structure 100 is the end away from the insulating structure 100.

[0112] As can be seen from the above, the insulating structure 100 provided in this embodiment can be applied to the valve tower 1 as an interlayer insulator 12. During the positioning process, the first protrusion 111 cooperates with the positioning pin 40 for positioning. The first protrusion 111 is thicker than the positioning pin 40. The first protrusion 111 has a greater structural strength than the positioning pin 40 and is not easily deformed, so that it is easy to smoothly position the support structure 20 and the insulating structure 100. The insulating structure 100 can also be applied to the valve tower 1 as a bottom insulator 11. The provision of the first protrusion 111 can improve the positioning efficiency between the insulating structure 100 and the first connecting structure 200, thereby improving the assembly efficiency between the insulating structure 100 and the first connecting structure 200, and further improving the assembly efficiency between the insulator assembly 10 and the external structure.

[0113] In some embodiments, Figures 8 to 10 As shown, the first end 110 is further provided with a second protrusion 112 protruding along the first direction, and the first connection structure 200 has a second matching hole 220 matched with the second protrusion 112 .

[0114] The first protrusion 111 and the second protrusion 112 are both arranged at the first end 110, and the first protrusion 111 and the second protrusion 112 are arranged at intervals. Exemplarily, the number of the second protrusion 112 is at least one, and the second protrusion 112 can be arranged in the peripheral area of ​​the first protrusion 111. The first protrusion 111 is also provided with a first locking hole 113 on the periphery, and the second protrusion 112 is arranged in an area of ​​the first end 110 where the first locking hole 113 is not provided. The second protrusion 112 can be arranged between two adjacent first locking holes 113, or the second protrusion 112 can be arranged in an area closer to the first protrusion 111 relative to the first locking hole 113, or the second protrusion 112 can be arranged in an area farther away from the first protrusion 111 relative to the first locking hole 113. Figure 8 As shown, there are multiple first locking holes 113, which are arranged at intervals and are annularly arranged around the outside of the first convex portion 111, and the distances between each first locking hole 113 and the first convex portion 111 are equal. There is one second convex portion 112, and in the end surface of the first end 110, the distance between the second convex portion 112 and the first convex portion 111 is smaller than the distance between the first locking hole 113 and the first convex portion 111.

[0115] like Fig. 9As shown, a second matching hole 220 is provided on the first connection structure 200, and the second matching hole 220 and the second protrusion 112 cooperate with each other, which means that the cross-sectional shape of the second matching hole 220 is the same as the cross-sectional shape of the second protrusion 112, and the inner diameter of the second matching hole 220 is the same as or close to the outer diameter of the second protrusion 112, so that the second protrusion 112 can extend into the second matching hole 220, and the inner wall of the second matching hole 220 has a certain limiting effect on the second protrusion 112, which can limit the movement of the second protrusion 112 in the radial direction. The number of the second matching holes 220 is greater than or equal to the second protrusion 112. When the number of the second matching holes 220 is greater than the number of the second protrusion 112, one second protrusion 112 extends into one of the second matching holes 220, and when the number of the second matching holes 220 is the same as the number of the second protrusion 112, the second protrusion 112 and the second matching holes 220 are arranged one by one. In this way, during the positioning process of the first connection structure 200 and the insulating structure 100, the first protrusion 111 can extend into the first matching hole 210, and the second protrusion 112 can extend into the second matching hole 220. The positioning of the insulating structure 100 and the supporting structure 20 can be achieved through the cooperation of the first protrusion 111 and the second protrusion 112, without the need to use the positioning pin 40, thus eliminating the step of removing the positioning pin 40 after the alignment is completed, thereby improving the assembly efficiency of the insulating structure 100 and the supporting structure 20.

[0116] In the first direction, the length H1 of the first convex portion 111 is greater than or equal to the length H2 of the second convex portion 112. In other words, in the first direction, the distance between the first convex portion 111 and the end surface of the first end 110 is greater than or equal to the distance between the second convex portion 112 and the end surface of the first end 110. In this arrangement, the second convex portion 112 will not be squeezed before the first convex portion 111 in most cases, that is, the squeezing force between two adjacent support structures 20 will not be concentrated only on the second convex portion 112. When the length H1 of the first convex portion 111 is equal to the length H2 of the second convex portion 112, the first convex portion 111 and the second convex portion 112 are subjected to force together. When the length H1 of the first convex portion 111 is greater than the length H2 of the second convex portion 112, the first convex portion 111 first bears the squeezing force. Since the first convex portion 111 shares the squeezing force with the second convex portion 112, it plays a certain protective role for the second convex portion 112, and reduces the possibility of deformation of the second convex portion 112 to a certain extent.

[0117] In some embodiments, Fig.10 and Fig.11As shown, in the first direction, the length H1 of the first convex portion 111 is greater than the length H2 of the second convex portion 112. In this arrangement, the first convex portion 111 is disposed more protruding from the first end 110 than the second convex portion 112, and thus will be subjected to a relatively greater extrusion force, while the first convex portion 111 has a relatively strong structural strength and is not easily deformed by compression, thereby playing a certain protective role for the second convex portion 112.

[0118] In one configuration, the number of the second matching holes 220 is greater than the number of the second protrusions 112. Fig.12 As shown, when the number of the second protrusion 112 is one, a plurality of second matching holes 220 may be provided on the first connection structure 200, and the plurality of second matching holes 220 are arranged in different directions of the outer periphery of the first matching hole 210. Fig.12 In the embodiment, there are four second matching holes 220, and the four second matching holes 220 are respectively located in four different directions of the first matching hole 210, and the four second matching holes 220 are symmetrically arranged in pairs relative to the first matching holes 210. With such an arrangement, when the first connection structure 200 is installed on the support structure 20, only a small range of rotation adjustment is required to make one of the second matching holes 220 located at a position opposite to the second protrusion 112, so as to facilitate the installation of the first connection structure 200 on the support structure 20.

[0119] In one possible design, Fig.13 As shown, the maximum outer diameter of the second protrusion 112 is greater than the minimum inner diameter of the first locking hole 113 .

[0120] When the second convex portion 112 is a constant diameter structure, in a cross section perpendicular to the first direction, the outer diameters of the second convex portion 112 are equal at various locations, and the outer diameter is the maximum outer diameter of the second convex portion 112. When the second convex portion 112 is a variable diameter structure, in a cross section perpendicular to the first direction, the outer diameters of different regions of the second convex portion 112 may be different, and the maximum value among the multiple outer diameter values ​​is the maximum outer diameter of the second convex portion 112.

[0121] The outer diameter of the second convex portion 112 is the diameter of its inscribed circle. For example, when the cross section of the second convex portion 112 is circular, its outer diameter is its diameter; when the second convex portion 112 is non-circular, its outer diameter is the diameter of its inscribed circle.

[0122] When the first locking hole 113 is a hole of equal diameter, in a cross section perpendicular to the first direction, the inner diameters of the first locking hole 113 at various locations are equal, and the inner diameter is the minimum inner diameter of the first locking hole 113. When the first locking hole 113 is a hole of variable diameter, in a cross section perpendicular to the first direction, the inner diameters of different regions of the first locking hole 113 may be different, and the minimum value among the multiple inner diameter values ​​is the minimum outer diameter of the first locking hole 113.

[0123] The inner diameter of the first locking hole 113 is the diameter of its inscribed circle. For example, when the cross section of the first locking hole 113 is circular, its inner diameter is its diameter; when the first locking hole 113 is non-circular, its inner diameter is the diameter of its inscribed circle. Fig.13 As shown, the first locking hole 113 is an oblong, or runway-shaped, and is surrounded by two symmetrically arranged arc-shaped side walls and two oppositely and parallelly arranged straight-surface extending side walls, and the two ends of the two arc-shaped side walls are connected by two straight-surface side walls. The inner diameter of the first locking hole 113 of this shape is the diameter of the inscribed circle, and is equal to the diameter of the arc-shaped side wall.

[0124] In this arrangement, since the positioning pin 40 is inserted into the first locking hole 113 during the process of using the positioning pin 40 for auxiliary positioning, the outer diameter of the positioning pin 40 is smaller than the minimum inner diameter of the first locking hole 113, and the maximum outer diameter of the second protrusion 112 is larger than the minimum inner diameter of the first locking hole 113, so the second protrusion 112 is thicker than the positioning pin 40 that can be inserted into the first locking hole 113, and the structural strength of the second protrusion 112 relative to the positioning pin 40 is stronger. Compared with the use of the positioning pin 40 for auxiliary positioning, the use of the second protrusion 112 for auxiliary positioning, because the outer diameter of the second protrusion 112 is not limited by the inner diameter of the first locking hole 113, the outer diameter of the second protrusion 112 can be relatively larger, so that the structural strength of the second protrusion 112 is stronger and less prone to deformation. Since the second protrusion 112 does not affect the insertion of the first locking structure 300 into the first locking hole 113, there is no need to remove the second protrusion 112 after the insulating structure 100 and the first connecting structure 200 are aligned. Compared with the method of using the positioning pin 40 for auxiliary positioning, the auxiliary positioning is performed by the second protrusion 112, and there is no need to disassemble the second protrusion 112 and the insulating structure 100 after the positioning is completed. Therefore, the assembly time of the insulating structure 100 and the first connecting structure 200 is saved, and the assembly efficiency between the insulating structure 100 and the first connecting structure 200 is improved.

[0125] In a possible design, in the first direction, the length H1 of the first protrusion 111 is greater than the length H2 of the second protrusion 112 , and the maximum outer diameter of the second protrusion 112 is smaller than the maximum outer diameter of the first protrusion 111 .

[0126] When the first convex portion 111 is of a constant diameter structure, in a cross section perpendicular to the first direction, the outer diameters of the first convex portion 111 at various locations are equal, and the outer diameter is the maximum outer diameter of the first convex portion 111. When the first convex portion 111 is of a variable diameter structure, in a cross section perpendicular to the first direction, the outer diameters of different regions of the first convex portion 111 may be different, and the maximum value among the multiple outer diameter values ​​is the maximum outer diameter of the first convex portion 111.

[0127] The outer diameter of the first convex portion 111 is the diameter of its inscribed circle. For example, when the cross section of the first convex portion 111 is circular, its outer diameter is its diameter; when the first convex portion 111 is non-circular, its outer diameter is the diameter of its inscribed circle.

[0128] Since the maximum outer diameter of the second convex portion 112 is smaller than the maximum outer diameter of the first convex portion 111, the first convex portion 111 is thicker and has a stronger structural strength than the second convex portion 112. Since the length H1 of the first convex portion 111 is greater than the length H2 of the second convex portion 112 in the first direction, the first convex portion 111 will first contact the first connection structure 200, that is, if extrusion occurs between two adjacent support structures 20, the first convex portion 111 will be squeezed before the second convex portion 112. Since the first convex portion 111 has a stronger structural strength, the first convex portion 111 is less likely to deform. Since the first convex portion 111 has a certain protective effect on the second convex portion 112, the second convex portion 112 can be positioned without a strong structural strength without a large deformation, so the size of the second convex portion 112 does not need to be very large. The relatively smaller second convex portion 112 makes the weight of the insulating structure 100 relatively smaller on the basis of realizing the auxiliary positioning function. In addition, since a second matching hole opposite to the second protrusion 112 is provided on the first connection structure 200, the maximum outer diameter of the second protrusion 112 is smaller, so the inner diameter of the second matching hole is relatively smaller, thereby making the structural strength of the first connection structure 200 relatively stronger.

[0129] like Fig.11 As shown, in a possible design, the first protrusion 111 includes a first guide segment 1111 , and in a cross section perpendicular to the first direction, a cross-sectional area of ​​the first guide segment 1111 gradually decreases from a side close to the first end 110 to a side away from the first end 110 .

[0130] The cross-sectional area of ​​the first guide section 1111 gradually decreases from the side close to the first end 110 to the side of the first end 110, that is, the first guide section 1111 is a diameter-reducing section, and the cross-sectional area of ​​the first guide section 1111 on the side close to the first end 110 is larger, and the cross-sectional area away from the first end 110 is smaller. In this way, when the first protrusion 111 is inserted into the first matching hole 210, the cross-sectional area of ​​the first protrusion 111 on the side closer to the first matching hole 210 is smaller, and it is easier to extend into the first matching hole 210.

[0131] In a possible design, the first protrusion 111 includes a first limiting section 1113 , which is connected between the first guiding section 1111 and the first end 110 , and is an equal-diameter columnar structure extending along the first direction.

[0132] Exemplarily, the first limiting section 1113 may be a prism, a cylinder, an elliptical cylinder or other iso-diameter columnar structure. Since the first limiting section 1113 is located between the first guide section 1111 and the first end 110, the first guiding section 1111 first extends into the first matching hole 210, and the first guiding section 1111 is convenient for extending into the first matching hole 210. Since the first guiding section 1111 is connected to the first limiting section 1113, the distance between the supporting structure 20 and the first connecting structure 200 continues to decrease, and the first limiting section 1113 extends into the first matching hole 210. The distance between the outer peripheral surface of the first limiting section 1113 and the inner wall of the first matching hole 210 is relatively closer. That is to say, if the first protrusion 111 can contact the inner wall of the first matching hole 210, the setting of the first limiting section 1113 can increase the contact area between the first protrusion 111 and the inner wall of the first matching hole, reduce the shaking of the first protrusion 111 relative to the first matching hole 210 to a certain extent, and improve the stability of the first protrusion 111 inserted in the first matching hole 210.

[0133] In a possible design, the first matching hole 210 is a circular hole, the first guide section 1111 and the first limiting section 1113 are respectively coaxially arranged with the first end 110, the first guide section 1111 includes a truncated cone structure, and the first limiting section 1113 includes a cylindrical structure.

[0134] The first guide section 1111 may only include a truncated cone structure, or the first guide section 1111 may be partially a truncated cone structure and partially other structural shapes. Exemplarily, when the first guide section 1111 only includes a truncated cone structure, the end face of the first guide section 1111 away from the first limiting section 1113 is a plane. In another example, the first guide section 1111 includes a truncated cone structure and a spherical end portion, and the area of ​​the first guide section 1111 close to the first limiting section 1113 is a truncated cone structure, and a spherical end portion is provided on the side of the truncated cone structure away from the first limiting section 1113, and the bottom diameter of the spherical end portion is equal to the diameter of the end with a smaller diameter of the truncated cone structure, that is, the outer peripheral surface of the spherical end portion is relatively smoothly connected with the outer peripheral surface of the truncated cone structure. In this arrangement, the end face of the first guide section 1111 away from the first limiting section 1113 is an arc surface.

[0135] In this arrangement, the circular hole is easy to process and manufacture, and the circumference of the truncated cone-shaped structure and the cylindrical structure does not include edges. Therefore, during the alignment process, there will be no direct contact and relative friction between the edges and the inner wall of the circular hole, which can reduce the wear of the first protrusion 111 during the alignment process.

[0136] In a possible design, the second protrusion 112 includes a second guide segment 1121 , and a cross-sectional area of ​​the second guide segment 1121 gradually decreases from a side close to the first end 110 to a side away from the first end 110 .

[0137] The cross-sectional area of ​​the second guide section 1121 gradually decreases from the side close to the first end 110 to the side far from the first end 110, that is, the second guide section 1121 is a diameter-reducing section, and the cross-sectional area of ​​the side close to the first end 110 of the second guide section 1121 is larger, and the cross-sectional area far from the first end 110 is smaller. In this way, when the second convex portion 112 is inserted into the second matching hole 220, the cross-sectional area of ​​the side closer to the second matching hole 220 is smaller, and it is easier to extend into the second matching hole 220.

[0138] In a possible design, the second protrusion 112 includes a second limiting section 1123 , which is connected between the second guiding section 1121 and the first end 110 , and is an equal-diameter columnar structure extending along the first direction.

[0139] Exemplarily, the second limiting section 1123 may be a prism, a cylinder, an elliptical cylinder or other iso-diameter columnar structure. Since the second limiting section 1123 is located between the second guide section 1121 and the first end 110, the second guiding section 1121 first extends into the second matching hole 220, and the second guiding section 1121 is convenient to extend into the second matching hole 220. Since the second guiding section 1121 is connected to the second limiting section 1123, the distance between the supporting structure 20 and the first connecting structure 200 continues to decrease, and the second limiting section 1123 extends into the second matching hole 220. The distance between the outer peripheral surface of the second limiting section 1123 and the inner wall of the second matching hole 220 is relatively closer. That is to say, if the second protrusion 112 can contact the inner wall of the second matching hole 220, the setting of the second limiting section 1123 can increase the contact area between the second protrusion 112 and the inner wall of the first matching hole 210, reduce the shaking of the second protrusion 112 relative to the second matching hole 220 to a certain extent, and improve the stability of the second protrusion 112 inserted in the second matching hole 220.

[0140] In one possible design, Figure 4 , Figures 14 to 16As shown, the other end of the insulating structure 100 along the first direction has a second end 120, the second end 120 is protruding along the first direction with a third protrusion 121, and the second end 120 is also provided with a third locking hole 123; the insulator assembly 10 also includes a second connecting structure 400 and a second locking structure 500, the second connecting structure 400 has a third matching hole 410 that is matched with the third protrusion 121, and a fourth locking hole 430 that is opposite to the third locking hole 123, and the second locking structure 500 is used to penetrate the oppositely arranged third locking hole 123 and the fourth locking hole 430 to connect the second end 120 with the second connecting structure 400.

[0141] The third protrusion 121 can be arranged in the middle of the end surface of the second end 120, that is, the central axis of the insulating structure 100 along the first direction is collinear with the central axis of the third protrusion 121 along the first direction, or in other words, the third protrusion 121 is coaxially arranged with the insulating structure 100. If the end surface of the second end 120 is a circular surface, the third protrusion 121 is arranged at the center of the end surface and in the area around the center of the circle. In this arrangement, the first connection structure 200 and the insulating structure 100 can be aligned by the cooperation of the third protrusion 121 and the third matching hole 410. That is, it is convenient to position the first connection structure 200 and the insulating structure 100 at a coaxial arrangement. Of course, in other arrangements, the third protrusion 121 can also be arranged in an area relatively deviated from the middle of the end surface of the second end 120, that is, there is a certain distance between the central axis of the insulating structure 100 along the first direction and the central axis of the third protrusion 121 along the first direction, and they are not collinear.

[0142] like Figure 8 As shown, the second end 120 is provided with a third locking hole 123, and the third locking hole 123 is used for the second locking structure 500 to pass through. The third locking hole 123 is a through hole. The number of the third locking holes 123 can be multiple, and the multiple third locking holes 123 are spaced apart on the outer periphery of the third protrusion 121.

[0143] The second connection structure 400 and the first connection structure 200 are respectively connected to different support structures 20. The second connection structure 400 is provided with fourth locking holes 430. The number of the fourth locking holes 430 is the same as the number of the third locking holes 123, and the positions are opposite to each other.

[0144] When the third protrusion 121 is located in the middle of the end surface of the second end 120, a flange can be used as the second connection structure 400, a large hole with a larger inner diameter is provided in the middle of the flange, and a plurality of small holes with a smaller inner diameter for connection are provided on the periphery of the large hole. The large hole of the flange is used as the third matching hole 410, and the small hole of the flange is used as the fourth locking hole 430.

[0145] The second locking structure 500 is used to connect the insulating structure 100 with the second connecting structure 400, and the second locking structure 500 passes through the third locking hole 123 and the fourth locking hole 430. The second locking structure 500 may have the same structure as the first locking structure 300. Exemplarily, the second locking structure 500 includes a bolt and a nut.

[0146] In this arrangement, the second connecting structure 400 is used to connect to the support structure 20 of the submodule located above, the insulating structure 100 is positioned with the second connecting structure 400 via the third protrusion 121, and the insulating structure 100 is connected to the second connecting structure 400 via the second locking structure 500 through the third locking hole 123 and the fourth locking hole 430, so as to realize the connection between the insulating structure 100 and the support structure 20 of the submodule located above, thereby improving the connection efficiency.

[0147] In some embodiments, the third protrusion 121 is coaxially arranged with the second end 120, that is, the third protrusion 121 is arranged in the middle area of ​​the second end 120. Since the third protrusion 121 is arranged in the middle area of ​​the second end 120, the third protrusion 121 cooperates with the third matching hole 410, so that the coaxial positioning of the insulating structure 100 and the second connecting structure 400 is facilitated, that is, after the third protrusion 121 extends into the third matching hole 410, the insulating structure 100 and the second connecting structure 400 can be relatively limited in the horizontal direction (or any direction perpendicular to the first direction).

[0148] The third convex portion 121 may have the same structural shape as the first convex portion 111, and the third convex portion 121 may have the same size as the first convex portion 111. Of course, the third convex portion 121 may have a different structural shape and size from the first convex portion 111.

[0149] In a specific example, the structural shape of the third protrusion 121 can be the same as the structural shape of the first protrusion 111, the size of the third protrusion 121 can be the same as the size of the first protrusion 111, and the number of the first locking holes 113 is the same as the number of the third locking holes 123 and is arranged one by one. In this arrangement, the first locking structure 300 and the second locking structure 500 can be manufactured by using a flange of the same specification. For example, if the first end 110 is provided with a first protrusion 111 and a second protrusion 112, a hole can be punched on the flange at a position opposite to the second protrusion 112 to form a second matching hole 220, so that the flange is processed into the first connection structure 200 through a processing with fewer steps. When the second end 120 is only provided with the third protrusion 121 without other protruding structures, the flange can be directly used as the second connection structure 400 without further processing of the flange.

[0150] When the insulating assembly is used as an interlayer insulator 12 in the valve tower 1, Figure 6 and Figure 7 As shown, since the first end 110 is used to connect with the support structure 20 located below, and the second end 120 is located above the first end 110, the second end 120 is used to connect with the support structure 20 located above. During the installation of the valve tower 1, the second connection structure 400 is installed at the bottom of the upper support structure 20, and the second connection structure 400 and the support structure 20 can be connected by welding. Then the second end 120 of the insulating structure 100 is positioned and placed with the second connection structure 400. Specifically, the second end 120 is placed at a position opposite to the second connection structure 400, and then the insulating structure 100 is moved in a direction close to the second connection structure 400, and the third protrusion 121 extends into the third matching hole 410, so that the insulating structure 100 and the second connection structure 400 are initially positioned, that is, the insulating structure 100 and the second connection structure 400 can be relatively limited in the horizontal direction, so as to facilitate the subsequent locking and fixing operation. When the cross section of the third protrusion 121 is circular, the insulating structure 100 can rotate relative to the second connection structure 400, and when the cross section of the third protrusion 121 is non-circular, the insulating structure 100 cannot rotate relative to the second connection structure 400. When the cross section of the third protrusion 121 is circular, since in the process of fixing the insulating structure 100 and the support structure 20 located above, the insulating structure 100 is usually moved to be close to the support structure 20, and the weight of the insulating structure 100 is relatively lighter, it is convenient to position the insulating structure 100 and the second connection structure 400. Therefore, after the third protrusion 121 is inserted into the third matching hole 410, the insulating structure 100 can be rotated so that the third locking hole 123 is opposite to the fourth locking hole 430, so that the second locking structure 500 is inserted into the third locking hole 123 and the fourth locking hole 430, so as to fix the second end 120 of the insulating structure 100 and the second connection structure 400, that is, the insulating structure 100 is fixed on the support structure 20. Alternatively, during the alignment process, the positioning pin 40 may be inserted into the third locking hole 123 , and the insulating structure 100 and the second connecting structure 400 may be relatively positioned by means of auxiliary positioning by the positioning pin 40 .

[0151] like Fig.14 As shown, only one third protrusion 121 may be provided at the second end 120 of the insulating structure 100, or, as shown in FIG. Figures 17 to 21 As shown, the fourth protrusion 122 may be provided at the same time as the third protrusion 121 in the second section. In a possible design, as Fig.17 and Fig.18 As shown, the second end 120 is further provided with a fourth protrusion 122 , and the second connection structure 400 is provided with a fourth matching hole 420 matched with the fourth protrusion 122 .

[0152] During the process of aligning and installing the insulating structure 100 and the second connecting structure 400, as shown in FIG. Fig.19 As shown, the third protrusion 121 extends into the third matching hole 410, and the fourth protrusion 122 extends into the fourth matching hole 420, so as to position the insulation structure 100 and the second connection structure 400 for subsequent connection operations.

[0153] The fourth protrusion 122 and the third protrusion 121 are spaced apart on the second end 120. Through the cooperation between the fourth protrusion 122 and the third protrusion 121, not only the relative displacement of the insulating structure 100 and the second connecting structure 400 in any direction perpendicular to the first direction can be limited, but also the rotation between the insulating structure 100 and the second connecting structure 400 can be limited, so that the positioning effect between the insulating structure 100 and the second connecting structure 400 is better.

[0154] In one possible design, Fig.17 and Fig.19 As shown, the first end 110 is provided with a first protrusion 111 , and the second end 120 is provided with a third protrusion 121 , and the first protrusion 111 and the third protrusion 121 are coaxially arranged.

[0155] In this arrangement, the first end 110 is positioned with the support structure 20 located below through the first protrusion 111, and the second end 120 is positioned with the support structure 20 located above through the third protrusion 121, and positioning with the upper and lower support structures 20 can be achieved through a small number of protrusions. The coaxial arrangement of the first protrusion 111 and the third protrusion 121 facilitates the production and manufacture of the insulation structure 100.

[0156] For example, in a specific configuration, the first end 110 is provided with a first protrusion 111 and a second protrusion 112, and the second end 120 is provided with a third protrusion 121 and a fourth protrusion 122, the first protrusion 111 and the third protrusion 121 are coaxially arranged, and the second protrusion 112 and the fourth protrusion 122 are coaxially arranged. The structural shape of the third protrusion 121 is the same as that of the first protrusion 111, and the size of the third protrusion 121 is the same as that of the first protrusion 111. The structural shape of the fourth protrusion 122 is the same as that of the second protrusion 112, and the size of the fourth protrusion 122 is the same as that of the second protrusion 112. With such a configuration, the first connection structure 200 and the second connection structure 400 with the same structure can be adopted. For example, a flange may be used, and a hole may be opened on the flange. When the flange is used as the first connection structure 200, the hole is the second matching hole 220, and when the flange is used as the second connection structure 400, the hole is the fourth matching hole 420. In this way, the first connection structure 200 and the second connection structure 400 in the insulator assembly 10 may be manufactured using the same set of equipment and the same set of processing technology, without the need to set processing parameters separately, thereby simplifying the processing process.

[0157] In some valve towers 1, the insulation structure 100 is designed according to the creepage distance requirement so that the insulation structure 100 has a set installation angle, that is, after the insulation structure 100 is assembled into the valve tower 1, the first end 110 of the insulation structure 100 can only be connected to the support structure 20 below, and the second end 120 can only be connected to the support structure 20 above. Even if the number, size, and relative positions of the protruding structures arranged on the first end 110 and the second end 120 are the same, the second end 120 cannot be used interchangeably with the first end 110. In this way, in the process of connecting the insulation structure 100 with the support structure 20, it is necessary to distinguish the first end 110 and the second end 120 of the insulation structure 100.

[0158] In some embodiments, Fig. 22 and Fig.23As shown, the insulating structure 100 has a first end 110 at one end along the first direction and a second end 120 at the other end. The first end 110 is provided with a first protrusion 111 and a second protrusion 112. The second end 120 is provided with two fourth protrusions 122 protruding along the first direction. The distances between each fourth protrusion 122 and the axis of the second end 120 are equal. The second end 120 is also provided with a third locking hole 123; the insulator assembly 10 also includes a second connecting structure 400 and a second locking structure 500. The second connecting structure 400 has a fourth matching hole 420 arranged opposite to the fourth protrusion 122, and a fourth locking hole 430 arranged opposite to the third locking hole 123. The second locking structure 500 is used to penetrate the third locking hole 123 and the fourth locking hole 430 arranged opposite to each other to connect the second end 120 with the second connecting structure 400.

[0159] In this arrangement, the second end 120 of the insulating structure 100 is only provided with the fourth protrusion 122, but not the third protrusion 121, and the positioning between the insulating structure 100 and the supporting structure 20 is achieved through the cooperation of the two fourth protrusions 122, which facilitates the positioning and installation between the insulating structure 100 and the supporting structure 20. Since the second end 120 is not provided with the third protrusion 121 of a larger size, the weight of the insulating structure 100 can be reduced.

[0160] In a specific configuration, the first end 110 is provided with a first protrusion 111 and a second protrusion 112, and the second end 120 is provided with two fourth protrusions 122. The structural shape of the fourth protrusion 122 is the same as that of the second protrusion 112, and the size of the fourth protrusion 122 is the same as that of the second protrusion 112. In this configuration, the first end 110 is positioned with the first connection structure 200 by providing a relatively small number of first protrusions 111 and second protrusions 112, and the second end 120 is positioned with the second connection structure 400 by providing a relatively small number of fourth protrusions 122. Since only the first end 110 is provided with the first protrusion 111 of a larger size, and the second end 120 is not provided with the third protrusion 121 of a larger size, it can be judged whether the end is the first end 110 or the second end 120 by whether a protrusion of a larger size is provided. In this arrangement, the number of protrusions arranged on the insulating structure 100 is relatively small, and there are four protrusions in total, namely a first protrusion 111, a second protrusion 112 and two fourth protrusions 122. The two ends of the insulating structure 100 are respectively aligned and positioned by two protrusions, which avoids over-positioning to a certain extent and facilitates the production of the insulator assembly 10.

[0161] A specific embodiment of the present application provides an insulator assembly 10 , including an insulating structure 100 , a first connecting structure 200 , a first locking structure 300 , a second connecting structure 400 , and a second locking structure 500 .

[0162] The insulation structure 100 has a first end 110 and a second end 120 in a first direction. When the insulation structure 100 is installed in the valve tower 1, the first direction is a vertical direction. When the insulation structure 100 is installed in the valve tower 1, the second end 120 is located above the first end 110.

[0163] The first end 110 is provided with a first protrusion 111 and a second protrusion 112. The number of the first protrusion 111 and the second protrusion 112 are both one. In the first direction, the length H1 of the first protrusion 111 is greater than the length H2 of the second protrusion 112. The first end 110 is also provided with a plurality of first locking holes 113. The plurality of first locking holes 113 are arranged to form a circular area at intervals. The first protrusion 111 and the second protrusion 112 are both located in the area surrounded by the plurality of first locking holes 113. The first protrusion 111 is coaxially arranged with the first end 110, or in other words, the first protrusion 111 is located in the middle area of ​​the first end 110. The second protrusion 112 is located in the peripheral area of ​​the first protrusion 111. The first protrusion 111 includes a truncated cone-shaped first guide section 1111 and a cylindrical first limiting section 1113. The first guide section 1111 is connected to the first end 110 through the first limiting section 1113. The first end 110, the first guide section 1111 and the first limiting section 1113 are an integral structure. The cross-sectional shape of the first convex portion 111 is specifically circular, and the area surrounded by the hole wall of the first locking hole 113 is circular, and the outer diameter of the first limiting section 1113 is greater than the inner diameter of the first locking hole 113. The second convex portion 112 includes a truncated cone-shaped second guide section 1121 and a cylindrical second limiting section 1123. The second guide section 1121 is located on the side of the second limiting section 1123 away from the first end 110, and the second guide section 1121 is connected to the second limiting section 1123, and the first end 110, the second guide section 1121 and the second limiting section 1123 are an integral structure. The second guide section 1121 has a second guide surface that is relatively inclined to the first direction.

[0164] The second end 120 is provided with a third protrusion 121 and a fourth protrusion 122 protruding along the first direction. The third protrusion 121 is provided in the same manner as the first protrusion 111, and the fourth protrusion 122 is provided in the same manner as the second protrusion 112, which will not be described in detail here. The second end 120 is also provided with a third locking hole 123, and the third locking hole 123 is provided in the same manner as the first locking hole 113, which will not be described in detail here.

[0165] The first connection structure 200 has a first matching hole 210, a second matching hole 220 and a plurality of second locking holes 230. The first matching hole 210 is used for the first protrusion 111 to extend therein. The first matching hole 210 on the first connection structure 200 is arranged at a position opposite to the first protrusion 111 on the first end 110. When the first end 110 is connected to the first connection structure 200, the first limiting section 1113 extends into the first matching hole 210, and at least a portion of the first guide section 1111 extends out of the first matching hole 210. The second limiting section 1123 extends into the second matching hole 220, and at least a portion of the second guide section 1121 extends out of the second matching hole 220. The number of the second locking holes 230 is equal to the number of the first locking holes 113, and the first locking holes 113 and the second locking holes 230 are arranged in a one-to-one correspondence. The aperture of the first locking hole 113 is equal to the aperture of the second locking hole 230 , and both the first locking hole 113 and the second locking hole 230 are light holes.

[0166] The first locking structure 300 includes a bolt and a nut, the nut of the bolt abuts against an end of the first end 110 away from the first connecting structure 200, and the screw rod of the bolt passes through the first locking hole 113 and the second locking hole 230 in sequence, and a portion of the screw rod extends out of the second locking hole 230, and the nut is screwed on the portion of the screw rod extending out of the second locking hole 230, and the nut and the nut clamp the first end 110 of the insulating structure 100 and the first connecting structure 200 from both sides respectively.

[0167] The second connection structure 400 has a third matching hole 410 disposed opposite to the third protrusion 121, a fourth locking hole 430 disposed opposite to the third locking hole 123, and a fourth matching hole 420 disposed opposite to the fourth protrusion 122. The third matching hole 410 is disposed in the same manner as the first matching hole 210, the fourth locking hole 430 is disposed in the same manner as the second locking hole 230, and the fourth matching hole 420 is disposed in the same manner as the second matching hole 220, which will not be described in detail. As can be seen from the above, the second connection structure 400 can be disposed in the same manner as the first connection structure 200.

[0168] The second locking structure 500 is used to connect the insulating structure 100 to the second connecting structure 400, and the second locking structure 500 passes through the third stop hole and the fourth locking hole 430.
