[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0024] The following combination Figure 1-3 The specific embodiment of the present invention is described as follows: a temperature measuring tube for sintering photovoltaic silicon carbide panels, comprising:

[0025] The pipe body 1 has a heat-insulating cotton layer 11 on its outer circumference, and a heat-insulating tube 12 is provided inside the pipe body 1. The heat-insulating cotton layer 11 and the heat-insulating tube 12 can insulate the temperature measuring component 2 inside the heat-insulating tube 12 to prevent the temperature inside the furnace from being too high and damaging the measuring component. The heat-insulating tube 12 is provided with a spiral tube 122 for fluid circulation. Fluid circulates in the spiral tube 122. The cooling fluid circulates in the spiral tube 122 to achieve cooling of the interior of the heat-insulating tube 12.

[0026] The temperature measuring component 2 is installed in the insulation tube 12 and is used to measure the temperature inside the furnace;

[0027] The driving component 3 is installed at one end of the tube body 1, and is used to drive the temperature measuring component 2 to slide along the inner wall of the insulation tube 12 so that the temperature measuring component 2 extends out of the tube body 1 for temperature measurement. When the temperature measuring component 2 does not need to measure the temperature inside the furnace body, the temperature measuring component 2 is always located inside the spiral tube 122, and the tube body 1 and the insulation tube 12 isolate the temperature inside the furnace body, so that the temperature measuring component 2 is protected from the high temperature inside the furnace body. When the temperature measuring component 2 needs to measure the temperature of the furnace body, the driving component 3 drives the temperature measuring component 2 to move, so that the temperature measuring component 2 is moved out of the insulation tube 12 to measure the temperature of the furnace body, thereby avoiding the temperature inside the insulation tube 12 affecting the accuracy of the temperature measured by the furnace body. When the measurement of the furnace body temperature is completed, the temperature measuring component 2 is reset to the insulation tube 12 to protect it from the influence of high temperature, thereby improving the service life of the temperature measuring component 2.

[0028] Please refer to Figure 1As shown, a movable cavity 121 is formed inside the insulation tube 12, and the movable cavity 121 serves as the movement stroke of the temperature measuring component 2. The spiral tube 122 is distributed along the height direction of the insulation tube 12, and one end of the spiral tube 122 is connected with a water inlet pipe 123, and the water inlet pipe 123 is located at the lower end of the tube body 1. The other end of the spiral tube 122 is connected with a water outlet pipe 124, and the water outlet pipe 124 is located between the insulation tube 12 and the tube body 1, and extends to the lower end of the tube body 1. The spiral tube 122 is spirally distributed along the height direction of the insulation tube 12, and the low-temperature fluid is transported in a circulating manner in the spiral tube 122. The low-temperature fluid replaces the heat energy in the insulation tube 12 during the circulation process, thereby avoiding excessive temperature inside the insulation tube 12 and affecting the service life of the temperature measuring component 2.

[0029] Please refer to Figure 1 As shown, a pump body 129 is provided on the water inlet pipe 123, the input end of the pump body 129 is connected to the fluid storage container, and the output end thereof is connected to the water inlet pipe 123, and the end of the water outlet pipe 124 away from the spiral tube 122 is connected to the fluid storage container, the water inlet end of the pump body 129 is connected to the storage container for storing the fluid, and the water outlet end is connected to the water inlet pipe 123, and the water outlet pipe 124 serves as a return pipe of the spiral tube 122 to realize the circulation of the fluid.

[0030] Please refer to Figure 1 As shown, an installation step 125 is formed on the top of the insulation tube 12, and a closing plate 128 is provided on the installation step 125. The closing plate 128 is hingedly connected to the installation step 125. When the temperature measuring component 2 is located in the insulation tube 12, the closing plate 128 is in a closed state to prevent the temperature inside the furnace body from affecting the temperature inside the insulation tube 12. When the temperature measuring component 2 needs to measure the temperature inside the furnace body, the driving component 3 drives the temperature measuring component 2 to move so that it moves out of the insulation tube 12 to measure the temperature of the furnace body. During the movement of the temperature measuring component 2, the top of the temperature measuring component 2 can force the closing plate 128 to open outward, so that the temperature measuring component 2 can measure the temperature of the furnace body.

[0031] Please refer to Figure 1 As shown, there are multiple closing plates 128, and the multiple closing plates 128 are distributed in an array along the circumference of the end surface of the installation step 125.

[0032] Please refer to Figure 1-2 As shown, a hinge 126 is provided on the mounting step 125 , one end of the hinge 126 is fixedly connected to the mounting step 125 , and the other end thereof is fixedly connected to the closing plate 128 . The hinge 126 is used for the hinged connection between the closing plate 128 and the mounting step 125 .

[0033] Please refer to Figure 1-2As shown, a torsion spring 127 is provided on the hinge 126, and the legs of the torsion spring 127 are respectively in contact with the two ends of the hinge 126. The torsion spring 127 is used for the closing plate 128 to be in a normally closed state on the installation step 125. When the closing plate 128 is expanded outward, the torsion spring 127 is deformed and stores elastic potential energy. When the temperature measuring component 2 is reset to the inside of the insulation tube 12, the torsion spring 127 drives the closing plate 128 to reset and close, thereby isolating the temperature between the inside and outside of the insulation tube 12. It should be noted that when the temperature measuring component 2 is moved out of the insulation tube 12, the end of the temperature measuring component 2 cannot exceed the top of the closing plate 128 to prevent the temperature measuring component 2 from being unable to reset to the insulation tube 12.

[0034] Please refer to Figure 1 As shown, the driving component 3 includes a telescope 31, the fixed end of the telescope 31 is fixedly connected to the lower end of the tube body 1, and the temperature measuring component 2 includes a temperature measuring body 21, and the temperature measuring body 21 is fixedly connected to the output end of the telescope 31. The telescope 31 serves as a driving part for the temperature measuring component 2 to move in the insulation tube 12, so as to realize that the temperature measuring component 2 is located outside the insulation tube 12 when measuring temperature, and is located inside the insulation tube 12 when stopping temperature measurement, thereby effectively preventing the temperature measuring component 2 from being located in the furnace body for a long time from being affected by high temperature, thereby improving the service life of the temperature measuring component 2 and the accuracy of temperature measurement.

[0035] The working principle of this utility model:

[0036] The tube body 1 is installed on the furnace body and extends into the furnace body. A heat-insulating cotton layer 11 is provided on the tube body 1 to insulate the tube body 1. At the same time, a heat-insulating tube 12 is sleeved inside the tube body 1. A temperature measuring body 21 is installed inside the heat-insulating tube 12. The temperature measuring body 21, under the action of the heat-insulating cotton layer 11 and the heat-insulating tube 12, creates a large temperature difference between the inside and outside of the tube body 1, thereby protecting the temperature measuring component 2 from the influence of high temperature.

[0037] The spiral tube 122 in the thermal insulation tube 12 circulates a low-temperature fluid, and the pump body 129 draws the fluid from the fluid storage container, allowing it to enter the spiral tube 122 through the water inlet pipe 123 and eventually flow back to the fluid storage container through the water outlet pipe 124. The circulating flow of the fluid displaces the heat in the thermal insulation tube 12, thereby preventing the temperature measuring component 2 in the thermal insulation tube 12 from being damaged by high temperature.

[0038] When the temperature measuring assembly 2 stops working, the temperature measuring body 21 is located inside the temperature measuring body 21, and the closing plate 128 is in a closed state under the action of the torsion spring 127, so as to reduce the high temperature in the furnace body and transfer heat to the insulation tube 12. When the temperature measuring body 21 needs to detect the temperature inside the furnace body, the telescopic device 31 drives the temperature measuring body 21 to move so that it moves out of the insulation tube 12, wherein the top of the temperature measuring body 21 forces the closing plate 128 to expand. At this time, the torsion spring 127 deforms and stores elastic potential energy for resetting the closing plate 128, and the temperature measuring body 21 moves out of the insulation tube 12 to measure the temperature of the furnace body. During the movement of the temperature measuring body 21, the bottom movement distance shall not exceed the top of the expanded closing plate 128 to avoid the temperature measuring body 21 from being unable to reset. When the temperature measuring body 21 completes the temperature measurement, the telescopic device 31 drives the temperature measuring body 21 to reset so that it resets to the insulation tube 12 to avoid being affected by the high temperature of the furnace body.

[0039] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and 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.

[0040] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
