Description

Technical Field

[0001] The invention relates to the field of curved glass installation, and in particular to a device and method for installing and fixing vacuum pipe glass. Background Art

[0002] In modern vacuum pipeline systems, curved glass components, as important observation windows, must not only meet the requirements of high light transmittance and pressure resistance, but also have good sealing performance. Traditional vacuum pipeline glass fixtures mainly rely on mechanical fixation and adhesives to achieve the connection between glass components and pipeline bodies, but in actual applications, especially in harsh environments such as high temperature and humidity, the sealing performance is often difficult to guarantee, resulting in sealing failure, gas leakage and other problems.

[0003] Currently, most devices use a single sealing strip or glue layer to achieve sealing. However, these materials are prone to cracking or loosening under conditions such as high temperature, pressure changes, and aging, causing the sealing effect to gradually fail. Especially in high temperature environments, traditional glue layers often cannot maintain a stable sealing effect for a long time due to thermal expansion and contraction.

[0004] In the existing installation method, it is usually necessary to adjust and correct the contact pressure between the glass assembly and the pipe body multiple times, and traditional clamping devices such as bolts or clips are often difficult to apply the clamping force evenly, which can easily cause deformation of the glass assembly or loose installation.

[0005] In the existing device, the wooden or metal wedges used are easily worn during multiple disassembly and assembly processes, resulting in reduced accuracy of the installation process and reliability of the clamping force. After long-term use, fatigue loss of the wedges will also affect the stability of the entire device.

[0006] With the increasing demand for high precision and high safety of vacuum piping systems, how to improve the installation and fixation effect of glass components, enhance sealing and extend service life has become an urgent problem to be solved. At the same time, considering the installation efficiency and accuracy, the use of simple, fast and adjustable installation methods and devices has become the key. Summary of the invention

[0007] In a first aspect of the present disclosure, a device for installing and fixing vacuum pipe glass is provided, comprising:

[0008] The pipe body is provided with a plurality of openings, and an upper mold and a lower mold are provided on the side of each opening parallel to the pipe direction to form a clamping structure;

[0009] A curved glass component, covering the opening of the pipe body, for providing an observation window and achieving sealing;

[0010] A sealing strip, located between the curved glass assembly and the pipe body, for filling the gap and providing sealing;

[0011] A glue layer, used to fix the sealing strip between the pipe body and the curved glass assembly to improve the sealing performance;

[0012] The clamping device is used for clamping the curved glass component and the pipe body, and comprises a wooden wedge, which is inserted between the upper mold and the lower mold to provide a clamping force to fix the curved glass component on the pipe body.

[0013] In combination with the first aspect, the wooden wedge includes an upper wedge and a lower wedge, the upper wedge gradually increases in size from the insertion end to the withdrawal end, and squeezes the lower wedge when inserted, and the lower wedge gradually decreases in size from the insertion end to the withdrawal end, and squeezes the curved glass assembly when inserted.

[0014] A second aspect of the present disclosure provides a method for installing and fixing vacuum pipe glass, comprising:

[0015] Providing a pipe body, a surface of which is provided with a plurality of openings;

[0016] An upper mold and a lower mold are respectively arranged on the side of each opening parallel to the direction of the pipeline to form an I-shaped clamping structure;

[0017] Place a sealing strip on the contact surface between the opening edge and the pipe body, making sure it covers the entire opening edge;

[0018] Apply a layer of glue on the surface of the sealing strip to fix the sealing strip and enhance the sealing effect;

[0019] Cover the curved glass assembly on the opening so that its edge is close to the sealing strip and ensure that there is no obvious gap between the glass and the sealing strip;

[0020] Insert the lower wedge into the clamping structure space between the upper mold and the curved glass component, gradually insert the upper wedge above the lower wedge, gradually compress the lower wedge by extrusion, and then extrude the curved glass component to fix the curved glass component on the pipe body.

[0021] Beneficial effects: The present invention proposes a vacuum duct glass installation and fixing device and method. The device uses an innovative wooden wedge design and a clamping device, and utilizes a wedge structure to gradually increase the contact surface between the duct body and the glass assembly, thereby achieving a uniform and stable distribution of the clamping force, ensuring that the curved glass assembly is firmly fixed on the duct body. In addition, the use of multi-layer sealing strips and a glue layer with a self-healing function can not only effectively fill the sealing gap, but also cope with the problem of sealing failure caused by high temperature and climate change. Through this innovation, the installation stability and sealing performance of the vacuum duct glass assembly can be significantly improved, the service life can be extended, and the installation process can be simplified.

[0026] Here, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present disclosure.

[0027] The terms used in the disclosed embodiments are only for the purpose of describing specific embodiments and are not intended to limit the disclosed embodiments. The singular forms of "a", "said" and "the" used in the disclosed embodiments and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0028] Glass is widely used in large public buildings and visual pipeline construction. Glass can be used as an observation window for pipelines to facilitate observation of the internal conditions of the pipelines. Traditional curved glass installation technology has problems such as high construction difficulty, poor sealing of steel and glass under vacuum, and loose fixation of glass and supporting structure. The traditional installation method is to fix the curved glass on a rigid tooling with a curved surface shape consistent with the glass, thereby realizing the positioning and installation of bolts. Since the curved glass is a processed tempered glass with high rigidity, not easy to deform, and heavy weight, it is difficult to ensure the position accuracy of the bolt holes during positioning, punching and bolting installation. Although this positioning method meets the requirements of the assembly of curved glass, since a rigid tooling can only meet the installation of one type of glass, it reduces production efficiency and manufacturing flexibility, and increases the manufacturing cost and construction cycle of the product.

[0029] like Figure 1 Schematic diagram of a vacuum pipeline according to an embodiment of the present disclosure.

[0030] The main part in the figure is a cylindrical pipe, which represents the vacuum pipe body 110. Long strip openings 120 (windows) are distributed on the pipe, and these openings are used to install curved glass components (not shown) to provide observation windows.

[0031] On the outside of the pipe, there are equally spaced annular frames that are evenly arranged along the pipe body.

[0032] Prevent the pipe from deforming under high pressure or external force, especially play a structural support role around the curved glass installation area, ensure that the pipe will not be twisted due to thermal expansion, vibration or external load after the glass assembly is installed, and provide a stable fulcrum for clamping and fixing the curved glass assembly.

[0033] The curved glass covers the opening of the pipe. After installation, the curved glass fits tightly with the edge of the opening and is used to close the window, which not only provides an observation function but also ensures the vacuum tightness inside the pipe.

[0034] like Figure 2 It is a partial enlarged view of the single window of the vacuum duct according to the embodiment of the present disclosure.

[0035] The upper mold 210 is located above the glass component, is in a long strip shape, and extends along the pipeline direction. An I-shaped clamping structure is formed between the upper mold 210 , the lower mold 220 and the pipeline body 110 .

[0036] The arc design of the lower mold 220 is consistent with the curvature of the arc-shaped glass component, ensuring that the glass component can be stably embedded therein. The lower mold 220 provides bottom support and is in indirect contact with the glass component through the sealing strip to enhance the sealing effect.

[0037] The combination of the upper and lower molds forms a clamping space, and the glass components are evenly squeezed and fixed in the clamping space by applying external force, thereby avoiding glass breakage or displacement caused by uneven pressure distribution.

[0038] The sealing strips on both sides of the I-shaped structure are compressed to form a stable sealing interface, effectively preventing gas leakage. Especially in high temperature or air pressure fluctuation environments, this uniform clamping force distribution can prevent the sealing layer from failing. The upper and lower molds in the I-shaped structure can be matched with wooden wedges to further enhance the fixing effect. The wedges ensure the stability of the glass assembly by gradually increasing the pressure, while avoiding the sealing failure caused by looseness in traditional devices.

[0039] Combination Figure 3-Figure 4 The vacuum pipe glass installation and fixing method of the embodiment of the present disclosure specifically includes:

[0040] S301: providing a pipeline body, wherein a plurality of openings are arranged on the surface of the pipeline body;

[0041] S302: an upper mold and a lower mold are respectively arranged on the side of each opening parallel to the pipeline direction to form an I-shaped clamping structure;

[0042] S303: placing a sealing strip on the contact surface between the opening edge and the pipe body to ensure that it covers the entire opening edge, and applying a glue layer on the surface of the sealing strip to fix the sealing strip and enhance the sealing effect;

[0043] S304: Cover the curved glass assembly on the opening so that its edge is in close contact with the sealing strip, ensuring that there is no obvious gap between the glass and the sealing strip;

[0044] S305: inserting the lower wedge into the clamping structure space between the upper mold and the curved glass component, gradually inserting the upper wedge above the lower wedge, gradually pressing the lower wedge by extrusion, and then extruding the curved glass component to fix the curved glass component on the pipe body.

[0045] Specifically, S301: provide a pipe body, whose surface is provided with a plurality of openings. The pipe body is the main part of the overall structure, and is usually a hollow cylindrical shape or other shapes suitable for functional requirements.

[0046] Openings refer to window structures preset on the surface of pipes for light transmission, monitoring or other purposes. These openings are usually rectangular or curved in shape, matching the curved glass components.

[0047] The number, size and position of the openings can be flexibly designed according to functional requirements (such as installing optical components, sensors or ventilation equipment).

[0048] The material of the pipeline body can be metal (such as stainless steel, aluminum alloy) or composite material, and must have pressure resistance, corrosion resistance and high strength properties.

[0049] The edges of the openings need to be finely processed (such as deburring and smoothing) to avoid damage to the sealing components and the glass components.

[0050] S302: An upper mold 410 and a lower mold 420 are respectively set on the side of each opening parallel to the pipeline direction to form an I-shaped clamping structure. The upper mold and the lower mold are installed along the edge of the opening to form a supporting structure for clamping the glass assembly, which is in the shape of an "I" as a whole.

[0051] The materials of the upper and lower molds must have high rigidity and heat resistance to avoid deformation in environmental changes, which will cause the clamping effect to fail. The upper mold is installed on the upper part of the opening to press the glass component; the lower mold is located at the lower part of the opening to provide support. The I-shaped clamping structure has good mechanical properties and can evenly distribute the force on the glass component to prevent local overload and breakage.

[0052] The mold surface can be designed to be curved or flat, and the specific shape should be adjusted according to the curvature of the glass component. This clamping structure is also suitable for fixing other transparent materials (such as acrylic plates and polycarbonate plates), expanding its application range.

[0053] S303: Place a sealing strip 430 on the contact surface between the opening edge and the pipe body to ensure that it covers the entire opening edge, and apply a glue layer 440 on the surface of the sealing strip to fix the sealing strip 430 and enhance the sealing effect. The sealing strip 430 is a flexible material, usually made of rubber or silicone, which can fill the tiny gap at the opening edge. The glue layer 440 is used to adhere the sealing strip 430 to the pipe body to prevent it from moving during installation or use.

[0054] The glue layer 440 should be applied evenly to avoid excessive or insufficient glue in some areas, which may reduce the sealing performance. The thickness and width of the sealing strip 430 should be designed according to the size of the opening and the size of the glass component to ensure a tight fit.

[0055] In practical applications, a rubber strip with high temperature resistance or chemical corrosion resistance can be selected to adapt to special working conditions. The glue layer 440 can also be made of a two-component structural glue or a quick-drying glue to improve the bonding efficiency.

[0056] S304: Cover the curved glass assembly 450 on the opening so that its edge is close to the sealing strip 430, and ensure that there is no obvious gap between the glass and the sealing strip. The curved glass assembly 450 is a light-transmitting or transparent material that is consistent with the shape of the pipe opening and can completely cover the opening. During installation, it is necessary to ensure that the glass assembly 450 and the sealing strip 430 fit tightly without any gap to avoid air leakage or light leakage. The installation of the curved glass should avoid excessive mechanical stress to prevent the glass from breaking. The glass assembly can be made of tempered glass, laminated glass or other high-strength materials to improve its durability.

[0057] To further enhance the sealing effect, an auxiliary sealing material (such as sealant) may be coated on the edge of the glass.

[0058] For scenes that need to withstand high pressure, a reinforcement frame can be added outside the glass assembly.

[0059] S305: insert the lower wedge 460 into the clamping structure space between the upper mold 410 and the curved glass component 450, gradually insert the upper wedge 470 above the lower wedge 460, gradually compress the lower wedge 460 by extrusion, and then compress the curved glass component, and fix the curved glass component 450 on the pipe body. The lower wedge 460 and the upper wedge 470 are key components for gradually tightening the glass component. The lower wedge 460 provides initial support after insertion, and the upper wedge 470 compresses the glass component on the sealing strip 430 by overlapping and extruding.

[0060] The installation of the wedge block needs to be carried out in steps to ensure uniform force and avoid excessive force on the local part of the glass component. The material of the wedge block should have high hardness and wear resistance, and metal materials (such as stainless steel, alloy steel) are often used.

[0061] The wedge can be designed as a multi-stage or self-locking structure to further enhance the fixing effect.

[0062] In special applications, hydraulics can be used instead of manual insertion of wedges for a more efficient installation.

[0063] Beneficial effects: The seamless fit between the sealing strip and the glass component, combined with the mechanical compression of the coating glue layer and the wedge block, ensures the airtightness and safety of the pipeline. The installation steps for each opening are independent, suitable for multi-opening scenarios, and easy to maintain and replace. The I-shaped clamping structure and wedge block design provide uniform support and compression force, reducing the risk of component damage.
