Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curved glass, in particular to a large-size curved glass for pressure-resistant spherical observation cover. BACKGROUND

[0002] The manufacturing technology of large-size curved glass originates from the integration of architectural aesthetics and functional requirements, and its core lies in overcoming the contradiction between the inherent brittleness of glass material and the forming precision. In the early stage, the bending process of flat glass mainly adopted the gravity sag method, which relied on the self-weight natural bending of glass after being heated to the softening point. However, it was difficult to control the uniformity of curvature. In the mid-20th century, the mold pressing forming technology gradually matured, which obtained the preset curvature of glass in the softening state through the precise matching of high-temperature resistant alloy mold and the segmented temperature control system. However, it was limited by the mold cost and thermal stress distribution. With the development of aerospace materials, the hot bending process introduced the air floating support technology, which used high-pressure airflow to form a dynamic forming surface, and cooperated with the stress distribution algorithm of computer simulation to significantly improve the forming yield of super large curved glass. The breakthrough of chemical strengthening technology solved the mechanical strength problem of curved glass, which formed a compressive stress layer on the surface through ion exchange, so that the curved glass with a thickness of more than ten millimeters still maintained high transmittance and impact resistance. The current most advanced curved glass manufacturing has realized optical precision, adopted a multi-layer composite structure design, and embedded a flexible conductive film layer to meet the wind pressure requirements of building curtain wall while having intelligent dimming, photovoltaic power generation and other expansion functions. The technical difficulties mainly concentrate on the control of molecular structure stability and the elimination of edge stress in the hot bending process.

[0003] The existing observation cover curved glass mostly has the following shortcomings: first, in terms of sealing performance, the traditional O-ring and flange gasket are prone to thermal stress failure due to the mismatch of material thermal expansion coefficient and glass, which leads to micro-cracks on the sealing surface and medium leakage under the condition of severe temperature fluctuation. In terms of installation process, the bolt pre-tightening force completely depends on the experience of operators, which is easy to cause glass structure damage or sealing failure due to improper force. In terms of forming process, the conventional air cooling technology is difficult to adapt to the curved mutation area, which leads to uneven glass thickness distribution and self-explosion risk. In terms of structural design, the traditional perforated sensor installation method will damage the continuity of glass fibers, significantly reducing the overall bending strength. In terms of function realization, the existing monitoring system is mostly single parameter detection, lacking the prediction ability of combined failure modes such as thermal stress and deformation coupling. SUMMARY

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of the present invention will now be described.

[0022] A pressure-resistant spherical observation hood uses large-size curved glass, such as Figures 1-7 As shown, the device includes curved glass 1, a hydraulic ring 4 at the bottom of the curved glass 1, a hydraulic block 14 inside the hydraulic ring 4, a sealing ring 7 connected to one end of the hydraulic block 14, an inner sealing ring 15 at the bottom of the curved glass 1, multiple sets of shape memory alloy rings 9 on one side of the inner sealing ring 15, and multiple sets of limiting blocks 10 that cooperate with the shape memory alloy rings 9 on the outside of the inner sealing ring 15. An installation groove 16 is formed between the inner sealing ring 15 and the hydraulic ring 4. A slide rail 2 is provided on the outside of the hydraulic ring 4, and a wind-cooled rectangular block 3 is provided inside the slide rail 2. The device is designed to allow for the connection of various components. The staff places the curved glass 1 on the circular convex ring to be installed. Then, the staff applies the sealant to one end of the sealing ring 7 at the bottom of the main body and the outside of the inner sealing ring 15 to ensure the installation of the curved glass 1 is stable. When the curved glass 1 is used later, the fiber optic sensing grid 5 set inside the curved glass 1 achieves non-destructive integration, maintains the structural integrity of the curved glass 1, integrates stress, temperature and deformation data, sets composite thresholds, and has the effect of low false alarm rate.

[0023] For example, both sides of the hydraulic block 14 are connected to fixed blocks, the hydraulic ring 4 has a sealing cavity 8 that cooperates with the hydraulic block 14, the slide rail 2 has a sliding groove 11 that cooperates with the air-cooled rectangular block 3, and the top of the air-cooled rectangular block 3 has an air outlet. The multiple sets of air-cooled rectangular blocks 3 set inside the slide rail 2 are activated to run, and the cooling air is blown to the outside of the curved glass 1 through the angled air outlet set at the top of the air-cooled rectangular block 3. It can also cooperate with the slide rail 2 to move in a circle along the curved glass 1, so as to dynamically adjust the air volume and the position of the air vents, and optimize the cooling path for the curvature change area.

[0024] Exemplary, the curved glass 1 is internally provided with a mounting cavity 12, the mounting cavity 12 is internally filled with an optical fiber sensing grid 5, the optical fiber sensing grid 5 is provided with a conductive interface 13 penetrating the slide rail 2, the curved glass 1 is internally provided with a cavity 6, the hydraulic ring 4 is fixed at the top end of the curved glass 1 through polyurethane glue, and the memory alloy ring 9 is in an arc shape in the initial state, wherein, when the internal temperature of the curved glass 1 is relatively high, the optical fiber sensing grid 5 can accurately perceive and transmit electrical signals to an external control console, the hydraulic ring 4 is controlled to work through the external control console, that is, the hydraulic ring 4 fills hydraulic oil into the sealing cavity 8, so as to extrude the sealing ring 7 to move radially inward, so that the sealing ring 7 extrudes the externally fixed circular convex ring, and the thermal displacement difference between the glass and the flange is compensated in real time, at this time, the internal sealing ring 15 arranged at the bottom end of the curved glass 1 and the plurality of memory alloy rings 9 arranged outside the internal sealing ring 15 change the arc according to the temperature rise, so as to extrude the externally fixed circular convex ring from the inside to the outside, and the pressure distribution can also be monitored in real time through the optical fiber sensing grid 5, and the overpressure is automatically relieved, so as to avoid the effect of glass overload rupture.

[0025] The working principle of the present application is as follows: when in use, the curved glass 1 is placed on the circular convex ring to be installed by the staff, at this time, the sealing agent to be installed is applied to one end of the sealing ring 7 arranged at the bottom end of the main body and the outside of the internal sealing ring 15 by the staff, so as to ensure the stable installation of the curved glass 1.

[0026] When the curved glass 1 is used subsequently, the optical fiber sensing grid 5 arranged inside the curved glass 1 achieves lossless integration, maintains the structural integrity of the curved glass 1, fuses stress, temperature and deformation data, sets a composite threshold, and has the effect of small false alarm rate.

[0027] In this way, the plurality of air-cooled blocks 3 arranged inside the slide rail 2 are started to run, and the cooling air is blown to the outside of the curved glass 1 through the bevel blowing port arranged at the top end of the air-cooled block 3, and the slide rail 2 can also be started to run, and the slide rail 2 moves along the curved glass 1 in a circumferential direction, so as to achieve the effects of dynamically adjusting the air volume and the air hole position and optimizing the cooling path for the curvature mutation area.

[0028] When the internal temperature of the curved glass 1 is relatively high, the optical fiber sensing grid 5 can accurately perceive and transmit electrical signals to an external control console, the hydraulic ring 4 is controlled to work through the external control console, that is, the hydraulic ring 4 fills hydraulic oil into the sealing cavity 8, so as to extrude the sealing ring 7 to move radially inward, so that the sealing ring 7 extrudes the externally fixed circular convex ring, and the thermal displacement difference between the glass and the flange is compensated in real time.

[0029] At this time, the inner sealing ring 15 arranged at the bottom end of the curved glass 1 and the multiple sets of memory alloy rings 9 arranged outside the inner sealing ring 15 change the arc according to the temperature rise, thereby extruding the fixed circular convex ring outside from the inside to the outside, and the pressure distribution can be monitored in real time through the optical fiber sensing grid 5, and the automatic pressure relief is realized when the pressure is too high, so that the effect of avoiding overload and breakage of the glass is achieved.

[0030] Through the above structure, the effects of solving the problem of thermal stress sealing failure, thermal compensation ability, safety enhancement, space self-adaptive cooling, and multi-source risk collaborative early warning are achieved in the sealing performance.
