Abstract

This utility model relates to the field of pipeline insulation protection technology and discloses a retractable multi-segment insulating sleeve, including a retractable insulating sleeve and a quick-release installation assembly. This utility model allows manual pressing of the first and second limiting plates, driving them to move towards each other until they are in contact. At this point, the two sets of magnetic suction plates installed on the sides of the first and second limiting plates generate a corresponding magnetic attraction effect, facilitating the fixing of the retractable insulating sleeve to the surface of the external pipeline. For disassembly, the first limiting plate and buffer plate are manually pulled away from each other until the magnetic attraction effect between the two sets of magnetic suction plates disappears. During this process, the telescopic column generates a buffering force, controlling the first and second limiting plates to be in the open state, thereby achieving the technical effect of quick disassembly and installation of the retractable insulating sleeve on the surface of the external pipeline.

Description

Technical Field

[0001] This utility model relates to the field of pipeline insulation protection technology, and more specifically to a retractable multi-segment insulating sleeve, particularly to a retractable multi-segment insulating sleeve for wrapping around a pipeline to provide electrical insulation and / or physical protection, and especially to a multi-segment insulating sleeve structure with quick assembly and disassembly and stable connection functions. Background Technology

[0002] In industries such as power, chemical, machinery, and construction, insulating sleeves are frequently used to cover pipelines transporting fluids, gases, or cables to achieve purposes such as electrical insulation, corrosion protection, wear resistance, heat insulation, or labeling. The ease of installation and removal of insulating sleeves is particularly important in situations requiring regular pipeline inspection, maintenance, or replacement.

[0003] Currently, common pipe insulation sleeves (especially multi-section expandable structures) are typically installed and fixed using the following methods:

[0004] Tape wrapping / binding fixation: Using insulating tape, cable ties, etc., to wrap and fix the end of the sleeve to the pipe. This method is cumbersome and time-consuming. Disassembly requires damaging the tape or cutting the cable ties. It cannot be reused, is inefficient, and is extremely inconvenient in situations that require frequent disassembly and assembly.

[0005] Flange / clamp bolt connection: A flange or clamp is installed at the end of the sleeve, and the connection is secured with bolts and nuts. Although this method provides a relatively strong connection, it requires the use of tools (such as a wrench), involves multiple steps in assembly and disassembly, and is slow, especially in confined spaces or poorly lit environments. Furthermore, bolted connections are prone to loosening under vibration.

[0006] Simple snaps or Velcro: Some simple sleeves use snaps or Velcro connections. Although this method is relatively convenient for disassembly and assembly, its connection strength and sealing performance are usually poor. It is difficult to withstand the vibration, thermal expansion and contraction or external pulling force during pipeline operation, and it is easy to loosen or shift, resulting in insulation failure or reduced protection.

[0007] Therefore, there is an urgent need for a retractable multi-segment insulating sleeve to solve the aforementioned technical problems. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a retractable multi-segment insulating sleeve to solve the problems existing in the background art.

[0009] This utility model provides the following technical solution: a retractable multi-segment insulating sleeve, including a retractable insulating sleeve, wherein the upper surfaces of both ends of the retractable insulating sleeve are provided with quick-release installation components for fixing the retractable insulating sleeve to the outer surface of an external pipe. By providing quick-release installation components, the retractable insulating sleeve can be quickly installed on the surface of the external pipe and the retractable insulating sleeve on the surface of the external pipe can be quickly removed.

[0010] Furthermore, slot plates are installed on both sides of the retractable insulating sleeve, and telescopic columns are installed in the middle area on both sides of the two sets of slot plates. Each set of telescopic columns is composed of two sets of hollow columns connected together, and miniature springs are vertically installed on the inner sides of both ends of the two sets of telescopic columns.

[0011] Furthermore, a first limiting plate is provided on the side of a set of telescopic columns away from the slot plate, and a first limiting groove is opened on the inner wall of the first limiting plate near the slot plate. One end of a set of telescopic columns away from the slot plate is vertically installed on the inner side of the first limiting groove, and a second limiting plate is provided on the side of another set of telescopic columns away from the slot plate.

[0012] Furthermore, the second limiting plate has a second limiting groove on its inner wall near the slot plate, and the other set of telescopic columns is vertically installed on the inner side of the second limiting groove at one end away from the slot plate.

[0013] Both the first limiting plate and the second limiting plate are provided with magnetic plates on their outer sides near the slot plate, and the two sets of magnetic plates will generate a magnetic attraction effect.

[0014] An adsorption groove is provided on the inner side of the first limiting plate.

[0015] Furthermore, an adsorption plate is installed on the inner side of the adsorption tank, wherein the outer wall of the adsorption plate is covered with a rubber layer, and multiple sets of adsorption holes are opened at equal intervals on the inner wall of the adsorption plate. A buffer groove is opened on the inner side of the second limiting plate, and springs are installed vertically at equal intervals on the inner side of the buffer groove. A buffer plate is installed vertically on the end of the spring away from the second limiting plate.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model allows for manual pressing of the first and second limiting plates, driving them to move towards each other until they are in contact. At this point, the two sets of magnetic suction plates installed on the sides of the first and second limiting plates will generate a corresponding magnetic attraction effect, facilitating the fixation of the retractable insulating sleeve to the surface of the external pipe. During disassembly, the first limiting plate and buffer plate are manually pulled away from each other until the magnetic attraction effect between the two sets of magnetic suction plates disappears. During this process, the telescopic column generates a buffering force, controlling the first and second limiting plates to be in the open state, thereby achieving the technical effect of quick disassembly and installation of the retractable insulating sleeve on the surface of the external pipe.

[0018] 2. In this utility model, the adsorption plate contacts the surface of the external pipe. Under the action of the external pipe, the volume inside the adsorption plate will decrease, and a negative pressure adsorption effect will be generated between the adsorption holes of the adsorption plate and the external pipe, so as to further strengthen the adsorption force between the first limiting plate and the external pipe. At the same time, the spring is in a compressed state, which plays a certain buffering role. Attached Figure Description

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The retractable multi-segment insulating sleeve involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 2 As shown, this utility model provides a retractable multi-segment insulating sleeve, including a retractable insulating sleeve 1. The upper surfaces of both ends of the retractable insulating sleeve 1 are provided with quick-release installation components 2, which are used to fix the retractable insulating sleeve 1 to the outer surface of the external pipe. By providing quick-release installation components 2, the retractable insulating sleeve 1 can be quickly installed on the surface of the external pipe and the retractable insulating sleeve 1 on the surface of the external pipe can be quickly removed.

[0026] Reference Figures 1 to 4 As shown, this utility model provides a telescopic multi-segment insulating sleeve. The telescopic insulating sleeve 1 has slot plates 207 installed on both sides of both ends. Telescopic columns 209 are installed in the middle area on both sides of the two sets of slot plates 207. Each set of telescopic columns 209 is composed of two sets of hollow columns connected together. Miniature springs are vertically installed on the inner sides of both ends of the two sets of telescopic columns 209.

[0027] A first limiting plate 201 is provided on the side of a set of telescopic columns 209 away from the slot plate 207, and a first limiting groove 205 is provided on the inner wall of the first limiting plate 201 near the slot plate 207. One end of the set of telescopic columns 209 away from the slot plate 207 is vertically installed on the inner side of the first limiting groove 205.

[0028] Another set of telescopic columns 209 is provided with a second limiting plate 202 on the side away from the slot plate 207, and the second limiting plate 202 has a second limiting groove 208 on the inner wall near the slot plate 207. One end of the other set of telescopic columns 209 away from the slot plate 207 is vertically installed on the inner side of the second limiting groove 208.

[0029] The first limiting plate 201 and the second limiting plate 202 are both provided with magnetic plates 206 on their outer sides near the slot plate 207, and the two sets of magnetic plates 206 will generate a magnetic attraction effect.

[0030] The first limiting plate 201 has an adsorption groove on its inner side, and an adsorption plate 204 is installed on the inner side of the adsorption groove. The outer wall of the adsorption plate 204 is covered with a rubber layer. Multiple sets of adsorption holes are opened at equal intervals on the inner wall of the adsorption plate 204. The second limiting plate 202 has a buffer groove on its inner side, and springs 210 are installed vertically at equal intervals on the inner side of the buffer groove. A buffer plate 203 is installed vertically at the end of the spring 210 away from the second limiting plate 202.

[0031] In this embodiment of the application, the specific workflow of this part of the embodiment is as follows:

[0032] After manually attaching the retractable insulating sleeve 1 to the outer side of the external pipe, the first limiting plate 201 and the second limiting plate 202 are manually pressed to drive them to move towards each other until they are in contact. At this time, the two sets of magnetic suction plates 206 installed on the sides of the first limiting plate 201 and the second limiting plate 202 will generate a corresponding magnetic attraction effect, so as to fix the retractable insulating sleeve 1 to the surface of the external pipe. Compared with traditional fixing components, the overall installation efficiency will be improved by 60%. At the same time, when disassembling, the first limiting plate 201 and the buffer plate 203 are manually pulled to move away from each other until the magnetic attraction effect between the two sets of magnetic suction plates 206 disappears. During this process, the telescopic column 209 generates a buffer force to control the first limiting plate 201 and the second limiting plate 202 to be in the open state, thereby achieving the technical effect of quick disassembly and installation of the retractable insulating sleeve 1 on the surface of the external pipe.

[0033] During installation, the first limiting plate 201 and the second limiting plate 202 are installed together. The adsorption plate 204 comes into contact with the surface of the external pipe. Under the action of the external pipe, the volume inside the adsorption plate 204 will decrease. A negative pressure adsorption effect will be generated between the adsorption holes of the adsorption plate 204 and the external pipe, so as to further strengthen the adsorption force between the first limiting plate 201 and the external pipe. At the same time, the spring 210 is in a compressed state, which plays a certain buffering role.

[0034] The specific workflow for this application is as follows:

[0035] Installation and disassembly: The retractable insulating sleeve 1 is manually fitted onto the outer side of the external pipe. After the above steps are completed, the first limiting plate 201 and the second limiting plate 202 are manually pressed to drive them to move towards each other until they are in contact. At this time, the two sets of magnetic suction plates 206 installed on the sides of the first limiting plate 201 and the second limiting plate 202 will generate a corresponding magnetic attraction effect, so as to fix the retractable insulating sleeve 1 to the surface of the external pipe. Compared with traditional fixing components, the overall installation efficiency will be improved by 60%. At the same time, during disassembly, the first limiting plate 201 and the buffer plate 203 are manually pulled to move away from each other until the magnetic attraction effect between the two sets of magnetic suction plates 206 disappears. During this process, the telescopic column 209 generates a buffer force to control the first limiting plate 201 and the second limiting plate 202 to be in the open state, thereby achieving the technical effect of quick disassembly and installation of the retractable insulating sleeve 1 on the surface of the external pipe.

[0036] Buffering process: During the installation of the first limiting plate 201 and the second limiting plate 202, the adsorption plate 204 comes into contact with the surface of the external pipe. Under the action of the external pipe, the internal volume of the adsorption plate 204 will decrease, and a negative pressure adsorption effect will be generated between the adsorption holes of the adsorption plate 204 and the external pipe, so as to further strengthen the adsorption force between the first limiting plate 201 and the external pipe. At the same time, the spring 210 is in a compressed state, which plays a certain buffering technical effect.
