Description

Technical Field

[0001] This invention relates to the field of endoscopic monitoring technology, and in particular to a float glass endoscopic monitoring cooling device and its usage method. Background Technology

[0002] In the float glass manufacturing process, the tin bath is the core equipment for glass forming. It requires a highly sealed environment to ensure the molten glass spreads evenly and forms on the tin surface, ultimately resulting in stable-quality flat glass. To monitor the glass forming process and the operation of the edge-drawing machine in real time, the industry commonly uses endoscopic cameras inserted into the tin bath for visual monitoring. However, the operating temperature inside the tin bath can reach over 1200℃. This extreme high temperature environment not only directly damages the camera's electronic components, causing monitoring failure, but also affects the light transmission performance of the camera lens, thus failing to accurately reflect the production status. Therefore, a dedicated cooling device must be provided for the endoscopic camera.

[0003] In existing technologies, endoscopic camera monitoring requires a high degree of airtightness in the cooling device. The basic cooling device has an unreasonable cooling structure design and lacks optimization in the flow channel layout of the water cooling circuit, resulting in low heat dissipation area utilization. Moreover, lens cooling often adopts a single gas purging method, and the relative position design of the gas flow channel and the lens is not good, failing to form precise and efficient air cooling protection. The lens is prone to fogging or thermal deformation due to high temperature, affecting the clarity of monitoring. Summary of the Invention

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a float glass endoscopic monitoring and cooling device.

[0033] Specifically, the endoscopic assembly 1 includes a transmission component 11, which comprises an outer sleeve 111, a middle sleeve 112, and an inner sleeve 113 arranged sequentially from the outside to the inside. A hollow connecting rod 116 is disposed within the inner sleeve 113. An integrated component 12 is disposed at one end of the outer sleeve 111. An injection component 14 is disposed on the integrated component 12, including an injection pipe 141 for introducing cold water, an outlet pipe 142 for draining water, and an injection pipe 143 for introducing inert gas. A balancing component 15 is disposed within the integrated component 12. The device includes a fixed shell 151, a first connecting cylinder 152, and a second sealing cylinder 153 arranged sequentially from the outside to the inside. The fixed shell 151 has several drainage holes 1511. An elastic membrane 155 is fixed to the inner ring of the fixed shell 151. A buffer 157 for balancing air velocity is provided on the second sealing cylinder 153. A monitoring component 13 is provided at the other end of the outer shell 111. The monitoring component 13 includes a camera 131 located inside the inner shell 113. A lens port 135 is fixed at one end of the inner shell 113.

[0034] By using the transmission component 11, monitoring component 13, and balancing component 15, the multi-layer design of the transmission component 11, in conjunction with the injection component 14, can achieve a gas-liquid stratification design. While ensuring circulating liquid cooling, continuous blowing is achieved through gas transmission. This design not only uses water cooling to effectively control the temperature near the camera 131, but also the uniform blowing design can effectively prevent fogging and thermal deformation of the lens opening 135 due to high temperature, ensuring the clarity of the monitoring image. Furthermore, the gas flow can block the adhesion of dust and impurities in the tin bath, further improving the stability of monitoring.

[0035] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, spacers 114 are fixed between the inner ring of the outer sleeve 111 and the outer ring of the middle sleeve 112, and between the inner ring of the middle sleeve 112 and the outer ring of the inner sleeve 113, to ensure the connection stability of the outer sleeve 111, the middle sleeve 112 and the inner sleeve 113. A connecting sleeve 115 is fixed to the inner ring of the inner sleeve 113, and one end of the hollow connecting rod 116 is fixed inside the connecting sleeve 115.

[0037] A return water path is formed between the outer sleeve 111 and the middle sleeve 112 for the return transmission of cooling water to complete the circulating water cooling; a water inlet circuit is formed between the middle sleeve 112 and the inner sleeve 113 for the introduction and transmission of cooling water, so that the cold water is transmitted to the vicinity of the camera 131 for water cooling; the hollow connecting rod 116 is used to meet the gas transmission requirements and transmit inert gas to the inner sleeve 113.

[0038] Specifically, the integrated component 12 includes a sealing head 121 located on one side of the outer casing 111, a plug 1211 fixed at the center of one side of the sealing head 121, a transmission cavity 1212 opened inside the sealing head 121, and one end of the gas injection pipe 143 connected to the transmission cavity 1212 for guiding and transmitting inert gas.

[0039] The sealing head 121 seals one end of the device to ensure the overall sealing performance of the device, and at the same time, it works with the plug 1211 to supply power to the camera 131 through the cable.

[0040] Specifically, a sealing sleeve 122 is fixed to one end of the sealing head 121, a second spacer 124 is fixed between the inner ring of the sealing sleeve 122 and the outer sleeve 111, and a first spacer 123 is fixed between the inner ring of the sealing sleeve 122 and the middle sleeve 112.

[0041] The first spacer 123 and the second spacer 124 provide double sealing protection, ensuring the overall sealing performance of the device.

[0042] Specifically, one end of the first connecting cylinder 152 is fixed to the inner sleeve 113, and the other end of the first connecting cylinder 152 is fixed to the sealing head 121. One end of the second sealing cylinder 153 is fixed to the hollow connecting rod 116, and the other end of the second sealing cylinder 153 is fixed to the sealing head 121 and communicates with the transmission chamber 1212. The inert gas introduced into the gas injection pipe 143 is transmitted to the second sealing cylinder 153 through the transmission chamber 1212 and enters the sealing head 121.

[0043] Specifically, an auxiliary tube 156 is fixed to the top of the fixed shell 151. The top of the auxiliary tube 156 extends into the injection tube 141, and the bottom of the auxiliary tube 156 extends into the filter cylinder 154, so that the cold water injected through the injection tube 141 flows through the auxiliary tube 156 and enters the filter cylinder 154, and is discharged through several drainage holes 1511.

[0044] Specifically, the buffer 157 includes a first slider 1571 and a second slider 1572 respectively disposed on the inner rings of the two elastic films 155. A first inclined groove 1574 is provided on one side of the first slider 1571, and a hollow groove 1575 is provided through the center of the first inclined groove 1574. A second inclined groove 1577 is provided on one side of the second slider 1572.

[0045] Specifically, a protrusion 1576 is fixed at one end of the first slider 1571 and the second slider 1572. The first slider 1571 and the second slider 1572 are slidably connected to the second sealing cylinder 153 and pass through the first connecting cylinder 152 and are fixed to the elastic membrane 155 through the protrusion 1576. A fixing block 1573 is fixed at the center of the inner ring of the second sealing cylinder 153, and a flow-blocking groove 1578 is opened on one side of the fixing block 1573.

[0046] As shown in the attached diagram of the instruction manual. Figure 6 and Figure 7 As shown, the first slider 1571 near the transmission cavity 1212 is hollow. With this design, when the first slider 1571 is affected by airflow, the first inclined groove 1574 will cause the first slider 1571 to produce a relatively large displacement, and the gas will also continue to flow through the hollow groove 1575 and then contact the second slider 1572. With the cooperation of the second inclined groove 1577, the heavier second slider 1572 will produce a relatively small displacement, thus achieving dynamic balance adjustment.

[0047] When the incoming airflow velocity is large, the first slider 1571 is displaced significantly, and the gas transmitted through the empty slot 1575 will be directly sprayed onto the fixed block 1573, and then guided back by the flow obstruction slot 1578 to achieve gas buffering. This is well-suited for gas transmission scenarios and ensures the overall stability of gas output.

[0048] When cooling water is injected through the injection pipe 141 and the auxiliary pipe 156, it is first filtered by the filter cylinder 154, and then the cooling water enters the fixed shell 151, causing the elastic membrane 155 to undergo elastic deformation. Finally, it is evenly transmitted to the middle sleeve 112 and the inner sleeve 113 through the drain hole 1511.

[0049] When inert gas is injected through the injection pipe 143 and the transmission chamber 1212, it will enter the second sealing cylinder 153 and be balanced by the buffer 157 to ensure the stability of the gas entering the hollow connecting rod 116.

[0050] Specifically, the monitoring component 13 also includes an end cap 133 fixed to the outer sleeve 111, the middle sleeve 112, and the inner sleeve 113 for shielding and protecting the camera 131. The end cap 133 has a spacer 134 embedded on it to protect the lens opening 135. There is an exhaust gap between the spacer 134 and the lens opening 135. The lens opening 135 has several exhaust holes 1351 for inert gas to escape. A heat-conducting bracket 132 is screwed to one side of the camera 131, and one end of the heat-conducting bracket 132 is bolted to the connecting sleeve 115, as shown in the attached diagram of the instruction manual. Figure 4 As shown, there is an exhaust space between the heat-conducting bracket 132 and the connecting sleeve 115 for the transmission of inert gas.

[0051] As shown in the attached diagram of the instruction manual. Figure 4 As shown, the left ends of the middle sleeve 112 and the inner sleeve 113 are connected to the left ends of the outer sleeve 111 and the middle sleeve 112, which is used to allow cooling water to circulate.

[0052] Example 3, referring to Figures 2-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0053] In practical applications, the filter cartridge 154 is a stainless steel mesh plate with a nano-SiO2 superhydrophobic coating. The stainless steel mesh plate has a pore size of 1mm, a temperature resistance of ≥150℃, a hydrophobic angle of ≥125℃ for the nano-coating, and a scale adhesion of ≤0.2MPa. Even if the water temperature rises, scale cannot adhere to the mesh plate or the surface of subsequent high-heat components and is washed away by the large flow of water. The large pore size intercepts large particles of impurities in the water to prevent impurities from becoming scale nuclei and aggravating scale formation on high-heat components.

[0054] Scale inhibitors (such as polycarboxylic acid or phosphate) can also be placed inside the filter cartridge 154 to inhibit the crystallization of calcium and magnesium ions or disperse scale particles and prevent their adhesion.

[0055] In practical applications, the first connecting cylinder 152 is designed as a two-section pipe, with the two sections of pipe fixed together by a sealing flange. The fixed shell 151 is composed of two hollow semi-circular shells with a central angle of 180 degrees, and a sealing strip is provided between the two hollow semi-circular shells and fixed by bolts. With this design, the filter cylinder 154 can be disassembled and replaced or disassembled for cleaning while the first connecting cylinder 152 and the fixed shell 151 are detached.

[0056] Elastic Film 155 is a silicone rubber film with extremely high elasticity, an elongation of 500%-1200%, and a bending resistance of ≥10 times. 6 It is reliable in sealing against steam and high-temperature water at ≤150℃, resistant to aging and ozone, and does not crack with long-term use. It is well-suited for frequent deformation and range-based deformation scenarios.

[0057] In practical applications, the heat-conducting bracket 132 and the camera 131 are fixed and limited by a groove structure, and a buffer pad is provided in the groove. The buffer pad is used to absorb assembly stress and slight vibration (there is slight vibration of the equipment during the tin bath production process, which prevents the camera 131 from shifting), ensuring that the lens is always aligned with the center area of ​​the lens opening 135 and the monitoring angle is without deviation.

[0058] Specifically, all components in the device are made of 316 stainless steel, aluminum alloy, and aluminum-magnesium alloy polytetrafluoroethylene plastic.

[0059] In one embodiment, the components can also be connected in the following manner: the inner sleeve 113 is inserted into the slot of the integrated component 12 and welded along the outer side of the inner sleeve 113; the sealing sleeve 122 is welded to the sealing head 121; the outer sleeve 111, the middle sleeve 112, and the inner sleeve 113 are welded together by a spacer 114; the middle sleeve 112 is welded to the first spacer ring 123; the middle sleeve 112 is fitted over the inner sleeve 113; the lens port 135 is welded to the spacer ring 134; both the lens port 135 and the spacer ring 134 are welded to the end cap 133; the middle sleeve 112 and the first spacer ring 123 are integrally connected. The outer sleeve 111 is welded to the second spacer 124, the second spacer 124 is welded to the sealing sleeve 122, the liquid outlet pipe 142 and the liquid injection pipe 141 are welded to the sealing sleeve 122, the gas injection pipe 143 is welded to the sealing head 121, the camera 131 is installed to the heat-conducting bracket 132, the heat-conducting bracket 132 is installed to the connecting sleeve 115, the connecting sleeve 115 is installed to the hollow connecting rod 116, the hollow connecting rod 116 is installed to the sealing head 121, the plug 1211 is installed to the sealing head 121, and the plug 1211 is connected to the camera 131 via a cable.

[0060] A method of using a float glass endoscopic monitoring cooling device includes the following steps: Step 1: The device is pre-installed in the tin bath of the float glass production line. The camera 131 monitors the production inside the tin bath in real time, and cooling water is introduced through the liquid injection pipe 141 and inert gas for cooling is introduced through the gas injection pipe 143.

[0061] Step 2: Cooling water enters between the inner sleeve 113 and the middle sleeve 112, is transferred to the area around the partition sleeve 134, carries away the temperature around the partition sleeve 134 and the camera 131, and flows back between the outer sleeve 111 and the middle sleeve 112, and is finally discharged through the outlet pipe 142.

[0062] Step 3: In this step, inert gas enters the hollow connecting rod 116, is transmitted to the inner sleeve 113, passes through the evenly arranged exhaust holes 1351, and is discharged from the gap between the lens opening 135 and the spacer 134. This allows the cooling gas to be blown directionally and evenly across the surface of the lens opening 135, which effectively prevents the lens from fogging or thermal deformation due to high temperature, ensuring the clarity of the monitoring image. It also blocks dust and other impurities from adhering to the tin bath through gas flow, further improving the stability of the monitoring.

[0063] Step 4: During the actual water or gas supply process, due to process limitations and the tortuous nature of the pipeline, the water or gas supply uniformity fluctuates. When the cooling water enters the filter cylinder 154 through the auxiliary pipe 156, it will be filtered by the filter cylinder 154, causing the fixed shell 151 to fill with water, which will eventually be discharged through the drain hole 1511, and the elastic membrane 155 will undergo elastic deformation. Similarly, when the gas flows through the buffer 157, the first slider 1571 and the second slider 1572 will also be displaced.

[0064] It should be understood that when the cooling water input speed is high, the elastic diaphragm 155 is further deformed, causing the first slider 1571 and the second slider 1572 to move inward. However, with the cooperation of the first inclined groove 1574 and the second inclined groove 1577, the gas flow will generate resistance, thereby reducing the range of motion of the first slider 1571 and the second slider 1572, and reducing the degree of deformation of the elastic diaphragm 155. Similarly, if the cooling water input speed is low, under the gas transmission condition, the elastic diaphragm 155 deforms outward to reduce the water storage space inside the fixed shell 151, thereby achieving dynamic compensation.

[0065] Similarly, when gas transmission fluctuates, the presence of cooling water will also produce a reduction or compensation effect. The elastic film 155, the first slider 1571 and the second slider 1572 work together to reduce the amplitude of gas transmission fluctuations and ensure the stability of gas transmission.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
