Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, specifically to an anti-corrosion and heat preservation device for directly buried heating pipelines. Background Technology

[0002] Heating pipelines are an important component of urban heating systems, responsible for transporting heat energy generated by heat sources to individual homes. Heat is generated in equipment such as boilers, thermal power plants, and geothermal wells. A primary underground pipeline network connects the heat source and heat exchange stations. These heat exchange stations then convert the heat from the primary network into hot water or steam suitable for user consumption, which is then sent to a secondary pipeline network to deliver the heat to homes, thus achieving heat distribution.

[0003] The materials for heating pipelines can be selected based on specific project requirements and environmental conditions. Pipeline materials include steel pipes and plastic pipes. Directly buried heating pipelines also need to consider factors such as insulation, corrosion prevention, and safety. Therefore, during laying, a protective device needs to be installed on the outside of the pipeline. Traditional protective devices typically only wrap the outside of the pipeline with a layer of insulation material. While this method can provide some insulation, it does not provide comprehensive protection, making the pipeline highly susceptible to corrosion from groundwater in the soil, and the insulation effect is also poor. Therefore, a corrosion-resistant and insulation device for directly buried heating pipelines is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-corrosion and heat preservation device for directly buried heating pipelines, which has the advantages of simple installation and strong practicality, and solves the problem of poor anti-corrosion and heat preservation effect of traditional directly buried heating pipelines.

[0005] To achieve the above-mentioned goals of simple installation and high practicality, this utility model provides the following technical solution: a corrosion-resistant and heat-insulating device for a direct-buried heating pipeline, comprising a pipe body, a heat-insulating component disposed on the side of the pipe body, and a sealing component disposed on the side of the pipe body.

[0006] Furthermore, the insulation component includes several insulation plates fixedly installed on the side of the pipe body, a limiting groove opened on the side of the insulation plate, a support frame movably connected inside the limiting groove, an isolation plate fixedly installed on the top of the support frame, a positioning groove opened inside the pipe body, a sealing groove opened on the side of the pipe body, and a positioning seat fixedly installed at the bottom of the pipe body.

[0007] Furthermore, the tube is divided into an upper body and a lower body, both of which are semi-circular arc-shaped. The upper body and the lower body are spliced ​​together to form a circular tubular structure.

[0008] Furthermore, the insulation board is a circular tubular structure fixedly installed on the inner wall of the pipe body, and the support frame is a ring frame. The side of the support frame is provided with a fixedly installed locking block, which passes through the limiting groove and the inner wall of the pipe body for fixed installation.

[0009] Furthermore, the isolation plate is a circular tubular structure wrapped around the outer wall of the heating pipe. The positioning slot is opened on the opposite side surface of the upper and lower body. A sealing strip is inserted into the positioning slot at the top of the lower body. The sealing strip is embedded into the bottom of the upper body along the positioning slot at the bottom of the upper body.

[0010] Furthermore, the sealing assembly includes several pipe connection seats fixedly installed on the side of the pipe body, several pipe wall connection seats fixedly installed on the side of the pipe body, and a sealing ring fixedly installed inside the sealing groove.

[0011] Furthermore, the sealing groove is an arc-shaped groove opened on the side of the pipe openings at both ends of the upper and lower body, and the sealing ring is a circular ring embedded inside the sealing groove on the side of the upper and lower body.

[0012] Furthermore, the pipe connectors are evenly distributed on the outer walls of the upper and lower parts of the pipe body, and the upper and lower parts of the pipe connectors are evenly arranged on the sides of the lower part of the upper body.

[0013] Compared with the prior art, this utility model provides a corrosion-resistant and heat-insulating device for directly buried heating pipelines, which has the following beneficial effects:

[0014] 1. The anti-corrosion and heat preservation device for the direct-buried heating pipeline is constructed by placing the lower body into the trench where the pipeline is laid, embedding the positioning seat into the soil to maintain the stability of the bottom of the lower body, laying the insulation board on the inner wall of the lower body, fixing the support frame on the inner side wall of the pipe body, embedding the heating pipeline wrapped with the isolation plate into the inside of the support frame, then placing another part of the insulation board on the top of the support frame, inserting a sealing strip into the inside of the positioning groove, nesting the upper body positioning groove with the sealing strip, and then connecting and fixing the pipe wall connecting seats on the sides of the upper and lower bodies with bolts, thereby realizing the installation of the heating pipeline inside the device.

[0015] 2. The anti-corrosion and heat preservation device for this direct-buried heating pipeline works by filling the sealing groove with a sealing ring, aligning the front and rear ends of different pipes so that the two sides of the sealing ring are embedded in the sealing grooves on the sides of different pipes, and then fixing the pipe connection seats between different pipes with bolts. Because the connection between the front and rear of the pipes is filled with a sealing ring, and the connection between the upper and lower parts of the pipes is filled with a sealing strip, moisture in the soil is prevented from entering the device through the gaps between the pipes and corroding the heating pipeline. This solves the problem of poor anti-corrosion and heat preservation effect of traditional direct-buried heating pipelines. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 In this embodiment, a corrosion protection and heat preservation device for a direct-buried heating pipeline includes a pipe body 1, a heat preservation component 2 disposed on the side of the pipe body 1, and a sealing component 3 disposed on the side of the pipe body 1.

[0023] In this embodiment, the insulation component 2 includes several side insulation plates 21 fixedly installed on the side of the pipe body 1, a limiting groove 22 opened on the side of the insulation plate 21, a support frame 23 movably connected inside the limiting groove 22, an isolation plate 24 fixedly installed on the top of the support frame 23, a positioning groove 25 opened inside the pipe body 1, a sealing groove 26 opened on the side of the pipe body 1, and a positioning seat 27 fixedly installed on the bottom of the pipe body 1.

[0024] In this embodiment, the tube 1 is divided into an upper body 11 and a lower body 12. Both the upper body 11 and the lower body 12 are semi-circular arc-shaped. The upper body 11 and the lower body 12 are spliced ​​together to form a circular tubular structure.

[0025] In this embodiment, the insulation board 21 is a circular tubular structure fixedly installed on the inner wall of the pipe body 1, the support frame 23 is a ring frame, and the side of the support frame 23 is provided with a fixedly installed locking block 28, which passes through the limiting groove 22 and the inner wall of the pipe body 1 for fixed installation.

[0026] Insulation board 21 is placed on the inner wall of pipe body 1 to wrap the internal heating pipe and achieve the effect of heat preservation. Support frame 23 supports the heating pipe inside pipe body 1, thereby fixing the heating pipe inside pipe body 1.

[0027] It should be noted that the insulation board 21 consists of two parts, upper and lower, which facilitates advance arrangement.

[0028] In this embodiment, the isolation plate 24 is a circular tubular structure wrapped around the outer wall of the heating pipe. The positioning slot 25 is opened on the opposite side surface of the upper body 11 and the lower body 12. A sealing strip is inserted into the positioning slot 25 at the top of the lower body 12. The sealing strip is embedded into the bottom of the upper body 11 along the positioning slot 25 at the bottom of the upper body 11.

[0029] An isolation plate 24 is placed on the outside of the heating pipe to wrap the outer wall of the heating pipe, which increases the heat preservation effect and separates the heating pipe from the insulation plate 21. The space between the insulation plate 21 and the heating pipe is filled to minimize the amount of air inside the device, thereby avoiding corrosion of the pipe.

[0030] In this embodiment, the sealing assembly 3 includes several pipe connection seats 31 fixedly installed on the side of the pipe body 1, several pipe wall connection seats 32 fixedly installed on the side of the pipe body 1, and a sealing rubber ring 33 fixedly installed inside the sealing groove 26.

[0031] Pipe connection seat 31 and pipe wall connection seat 32 are provided on the side of the pipe body 1 to facilitate the installation and burial of the heating pipe. The sealing ring 33 seals the connection between the pipe bodies 1 to prevent moisture in the soil from entering the interior of the pipe body 1 and corroding the heating pipe.

[0032] In this embodiment, the sealing groove 26 is an arc-shaped groove opened on the side of the pipe openings at both ends of the upper body 11 and the lower body 12, and the sealing ring 33 is a circular ring and is embedded inside the sealing groove 26 on the side of the upper body 11 and the lower body 12.

[0033] Sealing slots 26 are provided at both ends of the upper body 11 and the lower body 12 to seal the connection interface between different pipe bodies 1 in conjunction with sealing rings 33, so that the heating pipe inside the pipe body 1 can be completely isolated from the outside world, thereby increasing the effect of corrosion prevention and heat preservation.

[0034] In this embodiment, the pipe connectors 31 are evenly distributed on the outer side walls of the upper body 11 and the lower body 12 of the pipe body 1, and the upper and lower parts of the pipe wall connectors 32 are evenly arranged on the side of the lower body 12 of the upper body 11.

[0035] The designer uses pipe connector 31 to fix different pipe bodies 1, and pipe wall connector 32 to connect the upper body 11 and the lower body 12, which facilitates the pre-embedding of heating pipes.

[0036] The working principle of the above embodiments is as follows:

[0037] By placing the lower body 12 into the trench for laying the pipe, embedding the positioning seat 27 into the soil to maintain the stability of the bottom of the lower body 12, laying the insulation board 21 on the inner wall of the lower body 12, and then fixing the support frame 23 on the inner side wall of the pipe body 1, embedding the heating pipe wrapped by the isolation plate 24 into the inside of the support frame 23, then placing another part of the insulation board 21 on top of the support frame 23, inserting a sealing strip into the inside of the positioning slot 25, nesting the upper body 11 positioning slot 25 with the sealing strip, and then connecting and fixing the pipe wall connecting seat 32 on the side of the upper body 11 and the lower body 12 with bolts, thereby realizing the fixing of the heating pipe inside the device.

[0038] In addition, after filling the sealing groove 26 with the sealing ring 33, the front and rear ends of different pipe bodies 1 are aligned so that the two sides of the sealing ring 33 are respectively embedded in the sealing groove 26 on the side of different pipe bodies 1. Then, the pipe connection seat 31 between different pipe bodies 1 is fixed with bolts. Since the connection between the front and rear of the pipe body 1 is filled with the sealing ring 33, and the connection between the upper body 11 and the lower body 12 of the pipe body 1 is filled with the sealing strip, the moisture in the soil is prevented from entering the device through the gaps between the pipe bodies 1 and corroding the heating pipe. This solves the problem of poor anti-corrosion and heat preservation effect of traditional direct-buried heating pipes.
