Description

Technical Field

[0001] The utility model relates to the technical field of insulation pipe bases, in particular to a geothermal hollow vacuum insulation pipe structure. Background Art

[0002] The exploitation of medium- and deep-layer geothermal resources mainly relies on manual drilling technology. Through drilling, the insulated pipe can be deeply inserted into the underground heat reservoir to effectively extract geothermal energy.

[0003] However, existing geothermal hollow vacuum insulated pipes are typically installed vertically, directly fixed to the ground. While this installation method is simple and straightforward, it places extremely high demands on the mounting base. Because the insulated pipes are often made of high-strength, corrosion-resistant steel, they often weigh a staggering 10 tons or even more. Consequently, during operation, the excessive pressure on the pipes can easily crush the entire base structure, rendering them insecurely fixed to the underground heat reservoir. Utility Model Content

[0004] In view of the above-mentioned defects, the present invention proposes a geothermal hollow vacuum insulation pipe structure, which solves the problem of damage of the traditional mounting base due to excessive pressure through the dispersion effect of the mounting plate and the mounting base.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A geothermal hollow vacuum insulation pipe structure includes an insulation pipe, a mounting base, a mounting plate and a raft plate. The bottom of the mounting base is pre-buried in the raft plate, and the bottom of the insulation pipe vertically passes through the mounting base and the raft plate. The top of the mounting base is fixedly installed with a horizontal mounting plate, and the inner side wall of the mounting plate is fixedly connected to the outer side wall of the insulation pipe.

[0007] The mounting base includes a square plate, connecting columns and embedded bolts, the side walls of the connecting columns are fixedly connected to the insulation pipe, the bottom wall of the connecting column is fixedly connected to the square plate, and the embedded bolts are fixedly connected to the raft plate and the square plate.

[0008] The mounting plate is circular; the connecting column is divided into an inner connecting portion and an outer connecting portion, the inner side of the inner connecting portion is fixedly connected to the insulation pipe, and the outer side of the inner connecting portion is fixedly connected to the outer connecting portion;

[0009] The inner connecting portion vertically connects the mounting plate and the square plate, and the lower end of the outer connecting portion is vertically mounted on the square plate.

[0010] The outer connecting portion is provided with an inclined surface, and the inclined surface is inclined downward from the inside to the outside.

[0011] The square plate is provided with a plurality of mounting holes, the ends of the embedded bolts pass through the mounting holes, the mounting holes expand from bottom to top, and the side walls of the mounting holes form an inclined angle α with the vertical line.

[0012] The embedded bolt is an L-shaped structure, the horizontal end of the embedded bolt is embedded in the raft plate, and the vertical end of the embedded bolt is vertically connected to the square plate.

[0013] The included angles β between any two adjacent connecting columns are equal.

[0014] The technical solution of the utility model may have the following beneficial effects:

[0015] 1. By pre-embedding the bottom of the mounting base within the raft, the entire insulation pipe structure receives an extremely stable foundation. As a large-area foundation structure, the raft evenly distributes the various loads borne by the insulation pipe and mounting base to the foundation below. Even when subjected to adverse factors such as external vibration and uneven settlement, the insulation pipe remains stable and upright, preventing tilt or shifting, significantly improving the reliability and durability of the entire system.

[0016] 2. The mounting plate is installed horizontally on top of the mounting base. Its inner wall is fixedly connected to the outer wall of the insulation pipe, so that the pressure of the insulation pipe can be more evenly distributed on the mounting plate. The mounting plate then transfers part of the pressure to the mounting base, and the mounting base evenly transfers the pressure to the raft plate, thereby dispersing the pressure and making the insulation pipe more firmly fixed to the mounting base.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0024] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] The following combination Figures 1 to 3 , describing a geothermal hollow vacuum insulation pipe structure according to an embodiment of the present utility model.

[0026] A geothermal hollow vacuum insulation pipe structure includes an insulation pipe 1, a mounting base 2, a mounting plate 3 and a raft 4. The bottom of the mounting base 2 is pre-buried in the raft 4. The bottom of the insulation pipe 1 vertically passes through the mounting base 2 and the raft 4. The top of the mounting base 2 is fixedly installed with the horizontal mounting plate 3, and the inner side wall of the mounting plate 3 is fixedly connected to the outer side wall of the insulation pipe 1.

[0027] By embedding the bottom of the mounting base 2 within the raft 4, the entire insulated pipe 1 structure receives an extremely stable foundation. As a large-area foundation structure, the raft 4 evenly distributes the various loads borne by the insulated pipe 1 and mounting base 2 to the underlying foundation. This ensures that the insulated pipe 1 remains stable and upright, preventing tilting or shifting, even when subjected to adverse external factors such as vibration and uneven settlement. This significantly improves the reliability and durability of the entire system.

[0028] Furthermore, the mounting plate 3 is mounted horizontally on top of the mounting base 2, with its inner sidewall fixedly connected to the outer sidewall of the insulation pipe 1. This allows the pressure of the insulation pipe 1 to be more evenly distributed on the mounting plate 3. The mounting plate 3 then transfers a portion of the pressure to the mounting base 2, which in turn evenly transfers the pressure to the raft 4, thereby dispersing the pressure and securing the insulation pipe 1 more securely to the mounting base 2.

[0029] Therefore, the problem of damage of the conventional mounting base 2 due to excessive pressure is solved through the dispersion effect of the mounting plate 3 and the mounting base 2 .

[0030] The mounting base 2 includes a square plate 21, a connecting column 22 and embedded bolts 23. The side walls of the multiple connecting columns 22 are fixedly connected to the insulation pipe 1, the bottom wall of the connecting column 22 is fixedly connected to the square plate 21, and the embedded bolts 23 fixedly connect the raft plate 4 and the square plate 21.

[0031] During the construction process, the embedded bolts 23 are pre-buried in the raft 4. When the square plate 21 contacts the raft 4, the nuts are tightened to tightly connect the mounting base 2 and the raft 4. This connection method has high strength and reliability, can withstand large tensile and shear forces, and ensures that the square plate 21 will not loosen or shift during long-term use.

[0032] Furthermore, the square plate 21, serving as the bottom support structure of the mounting base 2, has a large contact area. When pre-buried in the raft 4, it can evenly distribute the pressure from the insulation pipe 1 and the connecting column 22 to the raft 4, effectively preventing uneven settlement or structural damage caused by excessive local pressure.

[0033] Furthermore, the provision of multiple connecting posts 22 increases the number of contact points and connection strength between the mounting base 2 and the insulated tube 1. The sidewalls of the connecting posts 22 are fixedly connected to the insulated tube 1, effectively transmitting the various forces acting on the insulated tube 1. This multi-point connection ensures stable support for the insulated tube 1 in all directions, reducing the risk of deformation or damage due to uneven force.

[0034] The mounting plate 3 is circular; the connecting column 22 is divided into an inner connecting portion 24 and an outer connecting portion 25, the inner side of the inner connecting portion 24 is fixedly connected to the insulation pipe 1, and the outer side of the inner connecting portion 24 is fixedly connected to the outer connecting portion 25;

[0035] The inner connecting portion 24 vertically connects the mounting plate 3 and the square plate 21 , and the lower end of the outer connecting portion 25 is vertically mounted on the square plate 21 .

[0036] The circular mounting plate 3 has good mechanical properties. When subjected to pressure from the insulation pipe 1 and external forces, the circular shape can distribute stress more evenly over the entire mounting plate 3, reducing the phenomenon of local stress concentration and improving the stability of the entire structure.

[0037] The combined structure of the inner connecting portion 24 and the outer connecting portion 25 effectively disperses the weight of the insulated pipe 1 and external forces, improving the load-bearing capacity of the connecting column 22. The inner connecting portion 24 vertically connects the mounting plate 3 and the square plate 21, evenly transferring the weight of the insulated pipe 1 to the mounting base 2, thus preventing localized excessive force. The lower end of the outer connecting portion 25 is vertically mounted to the square plate 21, increasing the contact area between the connecting column 22 and the square plate 21, further improving the load-bearing capacity and enhancing the strength and stability of the connection.

[0038] The outer connecting portion 25 is provided with an inclined surface 26 , and the inclined surface 26 is inclined downward from the inside to the outside.

[0039] Inclined surface 26 alters the path of stress transmission from the insulated pipe 1 to the mounting plate 3 and connecting column 22. The stress originally perpendicular to the connecting column 22 and mounting plate 3 is decomposed by inclined surface 26 into two components: one perpendicular to inclined surface 26 and the other parallel to it. These two components are borne by different parts of the connecting column 22 and mounting plate 3, respectively. This reduces stress concentration in localized areas and effectively improves the stability of the entire structure.

[0040] The square plate 21 is provided with a plurality of mounting holes 27 , through which the ends of the embedded bolts 23 pass. The mounting holes 27 expand upward from bottom to top, and the side walls of the mounting holes 27 form an inclined angle α with the vertical line.

[0041] The angle α formed between the sidewall of mounting hole 27 and the vertical line provides a natural flow path for the solder. During the soldering process, once the solder melts, gravity and surface tension cause it to flow along the inclined surface and fill the angled area. This flow characteristic makes the soldering process smoother, reducing uneven accumulation of solder at the weld site or the risk of solder flowing into undesirable locations.

[0042] Furthermore, the inclined surface provides more space for solder to adhere and fuse, thereby enhancing the strength and stability of the weld. The solder accumulates within the angle, forming a thicker weld layer, which improves the load-bearing capacity and tensile strength of the weld.

[0043] The embedded bolt 23 is an L-shaped structure. The horizontal end of the embedded bolt 23 is embedded in the raft 4 , and the vertical end of the embedded bolt 23 is vertically connected to the square plate 21 .

[0044] The L-shaped embedded bolts 23 provide a more secure connection to the base of the insulation pipe 1. The horizontal ends are embedded in the raft 4, increasing the contact area and anchoring depth, better able to withstand vertical pressure from the insulation pipe 1 and the base. The anchoring of the horizontal ends of the L-shaped bolts in the raft 4 effectively resists this pullout force, preventing the installation base 2 from being lifted or displaced.

[0045] The vertical end is perpendicularly connected to the square plate 21, ensuring a tight and reliable connection between the bolt and the square plate 21, and preventing loosening or displacement during use.

[0046] The included angle β between any two adjacent connecting pillars 22 is equal.

[0047] When the angles between every two connecting columns 22 are equal, the various pressures exerted on the insulated pipe 1 are more evenly distributed across the connecting columns 22. Because the connecting columns 22 are distributed at equal angles, the pressure is not concentrated on any one connecting column 22, but is instead shared by all connecting columns 22. This balanced stress distribution significantly reduces the pressure on a single connecting column 22, lowering the risk of deformation or damage due to localized excessive pressure. This makes the entire base structure of the insulated pipe 1 more stable and significantly improves its deformation resistance.
