Description

Technical Field

[0001] This utility model belongs to the field of optical technology, and in particular relates to a fiber optic spectrometer. Background Technology

[0002] Fiber optic spectrometers are an important tool in the field of spectroscopy. They are mainly used to measure the intensity of light at different wavelengths. The light we encounter in our daily lives, such as sunlight and fluorescent light, is composed of a mixture of different colors of light. With a fiber optic spectrometer, we can decompose these composite lights into spectra of different colors (i.e., different wavelengths), thereby enabling detailed analysis of the properties of light. This tool has wide applications in many fields, such as environmental monitoring, biomedicine, and industrial analysis. It is an indispensable tool, especially in research and industrial production that require precise measurement of changes in light intensity.

[0003] Existing fiber optic spectrometers generate heat during use and use cooling fans to cool the internal components. However, in high-temperature environments, relying solely on cooling fans is insufficient to effectively cool the spectrometer, causing the internal temperature to rise continuously and affecting its detection accuracy.

[0004] In other words, traditional fiber optic spectrometers are not easy to cool down internally when used in high-temperature environments, which affects the detection accuracy of the fiber optic spectrometer. Utility Model Content

[0005] This invention addresses the problem that traditional fiber optic spectrometers are difficult to cool internally when used in high-temperature environments, thus affecting their detection accuracy. The following technical solution is proposed:

[0006] A fiber optic spectrometer, comprising:

[0007] The spectrometer body and the top plate, wherein the top plate is connected to the spectrometer body;

[0008] A driving component, the driving component being connected to the top plate;

[0009] The heat dissipation assembly includes a connector, a connecting wheel, a connecting rod, a moving part, a cavity, a condenser tube, and a heat-conducting plate. The driving part drives the connecting wheel to rotate through the connector. The moving part is connected to the connecting wheel through the connecting rod. The moving part drives the liquid inside the cavity to flow along the inside of the condenser tube. The condenser tube is connected to the spectrometer body through the heat-conducting plate.

[0010] As a preferred embodiment of the above technical solution, it further includes a barrier component, which includes a spring and a ball valve, wherein the ball valve is connected to both ends of the condenser tube via the spring.

[0011] As a preferred embodiment of the above technical solution, there are multiple heat-conducting sheets, and the multiple heat-conducting sheets are distributed in an equidistant array from one end to the other on the inner wall of the spectrometer body, for absorbing the heat generated inside the spectrometer body.

[0012] As a preferred embodiment of the above technical solution, the outer surface of the moving part is in contact with the inner wall of the cavity.

[0013] As a preferred embodiment of the above technical solution, the outer surface of one of the ball valves is in contact with the inner wall of the condenser tube, and the outer surface of the other ball valve is in contact with the inner wall of the cavity.

[0014] As a preferred embodiment of the above technical solution, the inner wall of the cavity is provided with a plurality of protrusions, and the outer surface of the moving part is provided with grooves corresponding to the protrusions, for limiting the moving direction of the moving part.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The temperature of the heat-conducting plate surface is driven by the liquid flowing inside the condenser tube, which avoids the problem that the temperature will continue to rise when the device is used in a high-temperature environment, thereby improving the performance of the device in a high-temperature environment.

[0017] (2) The combination of spring and ball valve allows the liquid inside the condenser tube and cavity to flow. The flowing liquid can effectively absorb the temperature of the heat-conducting plate surface, thereby improving the heat dissipation efficiency of the device. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1

[0026] This invention provides a fiber optic spectrometer, such as... Figures 1 to 5 As shown, it includes: a spectrometer body 1, a top plate 2, a drive unit 3, and a heat dissipation assembly. The drive unit 3 is a bidirectional drive motor. An air inlet is provided inside the spectrometer body 1, and a dustproof mesh is attached to the inner wall of the spectrometer body 1 at the position of the air inlet. The top plate 2 is connected to the spectrometer body 1. The drive unit 3 is connected to the top plate 2. The heat dissipation assembly includes a connector 4, a connecting wheel 5, a connecting rod 6, a moving part 7, a cavity 8, a condenser tube 9, and a heat-conducting plate 10. The heat dissipation assembly also includes (connecting plate one 13, connecting plate two 14, and a bottom plate 15). Connecting component 4 is a worm gear, and connecting wheel 5 is a worm. Connecting component 4 and connecting wheel 5 mesh with each other. Connecting component 4 and cavity 8 are connected to top plate 2 via connecting plate 13. Connecting wheel 5 is connected to bottom plate 15 via connecting plate 2. The outer surface of moving component 7 has a groove that surrounds moving component 7. When connecting wheel 5 drives connecting rod 6 to rotate along the groove on the surface of moving component 7, it will drive moving component 7 to move. When connecting rod 6 moves half a circle along the groove on the surface of moving component 7, continuing to move along the groove will cause moving component 7 to move in the opposite direction. When the connecting rod 6 rotates, it drives the moving part 7 to reciprocate. The connecting part 4 is connected to the two output ends of the driving part 3, and fan blades are provided at the edges of both connecting parts 4. The driving part 3 drives the connecting wheel 5 to rotate through the connecting part 4. The moving part 7 is connected to the connecting wheel 5 through the connecting rod 6. The moving part 7 drives the liquid inside the cavity 8 to flow along the inside of the condenser tube 9. The condenser tube 9 is connected to the spectrometer body 1 through heat-conducting plates 10. There are multiple heat-conducting plates 10, and the multiple heat-conducting plates 10 are located at one end of the inner wall of the spectrometer body 1. The heat-conducting plates 10 are arranged in an equidistant array towards the other end, and the entire heat-conducting plate 10 is made of copper. When the temperature inside the spectrometer body 1 rises during use, the heat-conducting plate 10 absorbs the temperature inside the spectrometer body 1 and, with the help of the fan blades, dissipates the heat inside the spectrometer body 1. The outer surface of the moving part 7 is in contact with the inner wall of the cavity 8. The inner wall of the cavity 8 is provided with multiple protrusions, and the outer surface of the moving part 7 is provided with grooves corresponding to the protrusions to limit the movement direction of the moving part 7.

[0027] The liquid flowing inside the condenser tube 9 raises the surface temperature of the heat-conducting plate 10, thus preventing the temperature from continuously rising when the device is used in a high-temperature environment, thereby improving the device's performance in high-temperature environments.

[0028] When the device is used in a high-temperature environment, the heat-conducting plate 10 first absorbs the temperature inside the spectrometer body 1. Then, the operator starts the drive unit 3. The drive unit 3 drives the connecting wheel 5 to rotate through the connecting part 4. The connecting wheel 5 drives the connecting rod 6 to rotate along the groove on the surface of the moving part 7. When the connecting rod 6 rotates on the surface of the moving part 7, the cooperation between the groove inside the cavity 8 and the moving part 7 causes the connecting rod 6 to drive the moving part 7 to move during the rotation. At this time, since the groove on the surface of the moving part 7 is annular, the connecting rod 6 drives the moving part 7 to move in a reciprocating state. And through the cooperation between the moving part 7 and the blocking component... When the moving part 7 moves away from the connecting wheel 5, it squeezes the liquid inside the cavity 8 into the condenser tube 9 through one end. When the moving part 7 moves closer to the connecting wheel 5, it draws the liquid inside the condenser tube 9 into the cavity 8 through the other end of the condenser tube 9. The liquid flowing inside the condenser tube 9 carries away the heat absorbed by the surface of the heat-conducting plate 10 and forms a conversion inside the cavity 8. The liquid flowing inside the condenser tube 9 drives the temperature of the surface of the heat-conducting plate 10, thus avoiding the problem of the temperature continuously rising when the device is used in a high-temperature environment, thereby improving the performance of the device in a high-temperature environment.

[0029] Specifically, a top plate 2 is installed on the top of the spectrometer body 1, a connecting plate 13 is fixedly connected to the bottom of the top plate 2, a bottom plate 15 is installed on the bottom of the spectrometer body 1, a connecting plate 2 14 is fixedly connected to the top of the bottom plate 15, a driving component 3 is installed inside the spectrometer body 1, a connecting component 4 is fixedly connected to the output shaft of the driving component 3 and sleeved inside the connecting plate 13, a connecting wheel 5 is meshed with the surface of the connecting component 4 and rotates inside the connecting plate 2 14, a connecting rod 6 is fixedly connected to one end face of the connecting wheel 5, a moving component 7 is slidably connected inside the connecting rod 6, a cavity 8 is slidably connected to the outer edge of the moving component 7, a condenser tube 9 is embedded inside the cavity 8 and both ends of the condenser tube 9 are embedded inside the cavity 8, and the outer surface of the condenser tube 9 is fixedly connected to the inner wall of the spectrometer body 1 through a heat-conducting plate 10.

[0030] To achieve the goal described above—that the liquid inside the condenser tube 9 enters the cavity 8 from one end and the liquid inside the cavity 8 enters the condenser tube 9 from the other end—the following solution is proposed: Figure 4 and Figure 5As shown, it also includes a barrier assembly, which includes a spring 11 and a ball valve 12. The ball valve 12 is connected to both ends of the condenser tube 9 by the spring 11. The outer surface of one ball valve 12 is in contact with the inner wall of the condenser tube 9, and the outer surface of the other ball valve 12 is in contact with the inner wall of the cavity 8.

[0031] The cooperation between spring 11 and ball valve 12 allows the liquid inside condenser tube 9 and cavity 8 to flow. The flowing liquid can effectively absorb the temperature of the heat-conducting plate 10, thereby improving the heat dissipation efficiency of the device.

[0032] In use, when the moving part 7 moves away from the connecting wheel 5, the pressure generated by the downward movement of the moving part 7 inside the cavity 8 causes one of the ball valves 12 to move. The moving ball valve 12 drives one of the springs 11 to stretch, causing the ball valve 12 to separate from the condenser tube 9. At this time, the liquid inside the cavity 8 enters the interior of the condenser tube 9 through the gap between the separated ball valve 12 and the condenser tube 9. Meanwhile, the other ball valve 12 remains in contact with the inner wall of the cavity 8 under the action of the spring 11. Conversely, when the other ball valve 12 separates from the inner wall of the cavity 8, one of the ball valves 12 remains in contact with the inner wall of the condenser tube 9, allowing the liquid inside the condenser tube 9 to enter the interior of the cavity 8 through the gap between the ball valve 12 and the cavity 8. Through the cooperation between the spring 11 and the ball valve 12, the liquid inside the condenser tube 9 and the cavity 8 can flow. The flowing liquid can effectively absorb the temperature of the surface of the heat-conducting plate 10, thereby improving the heat dissipation efficiency of the device.

[0033] Specifically, a spring 11 is fixedly connected to one edge of the inner wall of the condenser tube 9, and a ball valve 12 is fixedly connected to the other end of the spring 11. The ball valve 12 is in contact with the inner wall of the condenser tube 9. Another spring 11 and a ball valve 12 are fixedly connected to the other end of the condenser tube 9. The other ball valve 12 is in contact with the inner wall of the cavity 8.

[0034] Working Principle: When the device is used in a high-temperature environment, the heat-conducting plate 10 first absorbs the temperature inside the spectrometer body 1. Then, the operator starts the drive component 3. The drive component 3 drives the connecting wheel 5 to rotate through the connecting component 4. The connecting wheel 5 drives the connecting rod 6 to rotate along the groove on the surface of the moving component 7. When the connecting rod 6 rotates on the surface of the moving component 7, the cooperation between the groove inside the cavity 8 and the moving component 7 causes the connecting rod 6 to drive the moving component 7 to move. At this time, since the groove on the surface of the moving component 7 is annular, the connecting rod 6 drives the moving component 7 to move in a reciprocating state. Through the cooperation between the moving component 7 and the blocking component, when the moving component 7 moves away from the connecting wheel 5, the pressure generated by the moving component 7 moving downward inside the cavity 8 causes one of the ball valves 12 to move. Valve 12 stretches one of the springs 11, causing the ball valve 12 to separate from the condenser tube 9. At this time, the liquid inside the cavity 8 enters the interior of the condenser tube 9 through the gap between the separated ball valve 12 and the condenser tube 9. Meanwhile, the other ball valve 12 remains in contact with the inner wall of the cavity 8 under the action of the spring 11. Conversely, if the other ball valve 12 separates from the inner wall of the cavity 8, one ball valve 12 remains in contact with the inner wall of the condenser tube 9, allowing the liquid inside the condenser tube 9 to enter the interior of the cavity 8 through the gap between the ball valve 12 and the cavity 8. This creates a transformation process inside the cavity 8. The liquid flowing inside the condenser tube 9 raises the temperature of the surface of the heat-conducting plate 10, preventing the temperature from continuously rising when the device is used in a high-temperature environment, thereby improving the device's performance in high-temperature environments.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
