Description

Technical Field

[0001] The utility model belongs to the technical field of radiation measurement, and more specifically, relates to a thermal radiation measurement device. Background Art

[0002] Since the thermal radiation values ​​at different distances and heights from the flame are different, a large number of thermal radiation meters are needed to fully obtain the thermal radiation values ​​at different positions. However, thermal radiation meters are relatively expensive, so the cost of the test is very high. The installation of a large number of thermal radiation meters is also very cumbersome, and it is necessary to measure the horizontal distance of the thermal radiation meter from the flame, the height from the ground, etc. If the installation position of the thermal radiation meter is found to be unreasonable during measurement, it will take a long time to adjust it.

[0003] What is expected during measurement is the maximum thermal radiation value at a certain point. The thermal radiation value measured by the thermal radiation meter at a certain point is also related to the installation angle of the thermal radiation meter. Different installation angles will result in large differences in the measured thermal radiation values. Therefore, the installation angle of the thermal radiation meter needs to be adjusted during measurement in order to measure the maximum thermal radiation value. However, the existing measurement device can only detect the thermal radiation amount within a small range and is not convenient to operate. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] See also Figure 1 and Figure 2 Now, a thermal radiation measuring device provided by the utility model is described. A thermal radiation measuring device includes: a base 1, a support frame 5, a connecting sleeve, a mounting frame 7, a curved plate 10 and a plurality of thermal radiation meters 9. The support frame 5 is rotatably arranged on the base 1, and an extension rod is arranged on the side wall of the support frame 5. The connecting sleeve is rotatably sleeved on the extension rod. The mounting frame 7 is fixed to the end of the connecting sleeve away from the extension rod. The curved plate 10 is slidably arranged in the mounting frame 7. A plurality of thermal radiation meters 9 are sequentially mounted on the outer surface of the curved plate 10, and the plurality of thermal radiation meters 9 are used to adjust the spatial position and angle with the help of the mounting frame 7 and the connecting sleeve.

[0029] The beneficial effect of a thermal radiation measuring device provided by the utility model is that: compared with the prior art, in a thermal radiation measuring device of the utility model, a support frame 5 is rotatably arranged on a base 1, and an extension rod is arranged on a side wall of the support frame 5. A connecting sleeve is sleeved on the extension rod, and a mounting frame 7 is fixed to the end of the connecting sleeve away from the extension rod. The annular plate is slidably arranged in the mounting frame 7. A plurality of thermal radiation meters 9 are sequentially mounted on the side of the arc plate 10.

[0030] In practical applications, the rotation of the support frame 5 can change the orientation of multiple thermal radiation meters 9 at the same time, and by adjusting the connecting sleeve and changing the position of the arc plate 10 relative to the mounting frame 7, the spatial position and angle of the thermal radiation meter 9 can be changed. In the present application, the detection range of the thermal radiation meter 9 can be increased by the cooperation of the mounting frame 7 and the connecting sleeve and other components, the applicability is strong and the overall device is easy to adjust, so that the final detection effect is better.

[0031] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 , a worm wheel 3 is mounted on the bottom of the support frame 5, and a worm 4 connected to the worm wheel 3 is installed on the base 1. The support frame 5 needs to have its own circumferential rotation freedom, and needs to be able to adjust the angle of the support frame 5 relative to the base 1 according to the needs of actual use. In order to achieve the above-mentioned technical effect, firstly, a worm wheel 3 is mounted on the support frame 5, and a worm 4 is rotatably installed on the base 1, and the worm 4 is matched with the worm wheel 3. In actual application, by rotating the worm 4, the worm wheel 3 can be driven to rotate, and the rotation of the worm wheel 3 can also change the angle of the entire support frame 5. More importantly, the cooperation between the worm wheel 3 and the worm 4 has a certain self-locking characteristic, thereby ensuring the stability of the position of the support frame 5.

[0032] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 , a limit ring is provided on the inner wall of the connecting sleeve, and the limit ring is in sliding cooperation with the extension rod. Because the connecting sleeve needs to be able to rotate on the extension rod, the connecting sleeve needs to have the freedom to rotate around its own circumference, and the connecting sleeve is the key to stabilizing the mounting frame 7 and multiple thermal radiation meters 9. In order to prevent the connecting sleeve from slipping off the extension rod, an annular groove can be opened in the circumference of the extension rod in advance, and the limit ring on the connecting sleeve is in sliding cooperation with the annular groove. In an embodiment, the extension rod is composed of two parts, and after the two parts are spliced, an annular groove that effectively limits the limit ring will be formed at the connection.

[0033] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 , a limiting groove having the same curvature as the arc plate 10 is provided in the mounting frame 7. The arc plate 10 can move in the mounting frame 7, because when the position of the arc plate 10 changes, the positions of the corresponding multiple thermal radiation meters 9 will also change accordingly, and since the positions of the thermal radiation meters 9 on the arc plate 10 are different, based on the above reasons, the radiation amounts that can be detected by the thermal radiation meters 9 are different.

[0034] In order to enable the arc plate 10 to move, a limit groove needs to be opened in the mounting frame 7. The limit groove is an arc groove, and more importantly, the center of the limit groove is at the same point as the center of the arc plate 10. Only with the above design can it be ensured that the arc plate 10 moves a certain distance in the limit groove.

[0035] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1The mounting frame 7 is provided with a first motor for driving the arc plate 10 to move. In order to drive the arc plate 10 to move, the first motor can be installed on the mounting frame 7, and an output wheel is provided on the output shaft of the first motor. The output wheel is connected to the back side of the arc plate 10, that is, the side away from the plurality of thermal radiation meters 9. The transmission connection can be friction transmission and gear transmission. The mounting frame 7 is provided with a plurality of driving wheels 8, and the plurality of driving wheels 8 cooperate to drive the arc plate 10 to move.

[0036] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 Figure 2 , a rack that cooperates with the first motor is provided on the side of the arc plate 10 away from the plurality of thermal radiation meters 9. For a more detailed description, a rack is provided on the back of the arc plate 10, the rack has a certain curvature, and it is necessary to ensure that the rack can always cooperate with the first motor during the movement of the arc plate 10. Through the above design, the position of the arc plate 10 can be changed by the first motor according to the use requirements.

[0037] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 , a second motor driving the connecting sleeve to rotate is installed on the extension rod. Usually, the extension rod is arranged perpendicular to the support frame 5, and the connecting sleeve is arranged coaxially with the extension rod in order to be able to rotate on the extension rod, and the rotation of the connecting sleeve will drive the mounting frame 7 to rotate, and the rotation of the mounting frame 7 will drive the arc plate 10 and multiple thermal radiation meters 9 to move. Therefore, in order to drive the connecting sleeve to rotate, a second motor is installed on the extension rod, and the second motor is in transmission cooperation with the connecting sleeve. Through the second motor, the position of the connecting sleeve can be accurately adjusted, and finally the spatial angle of the thermal radiation meter 9 can be changed.

[0038] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 The connecting sleeve is provided with a driving tooth that is conventionally matched with the second motor. The driving tooth is mounted on the outside of the connecting sleeve, and in order to ensure smooth transmission, the driving tooth can be directly welded and fixed on the connecting sleeve. More importantly, the limiting effect of the limiting ring can ensure that the driving tooth and the second motor always maintain a stable transmission relationship.

[0039] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1, a counterweight 6 is provided on the side of the support frame 5 away from the extension rod. The mounting frame 7, the arc plate 10, the plurality of thermal radiation meters 9 and the connecting sleeve all have a certain mass. In order to ensure that the support frame 5 is subjected to a stable force and that the support frame 5 can be stably arranged on the base 1, a counterweight 6 is provided in the direction of the support frame 5 away from the mounting frame 7. The ultimate effect is that the counterweight 6 is provided to reduce the horizontal force on the support frame 5 and reduce the problem of stress concentration between the support frame 5 and the base 1.

[0040] In some embodiments of a thermal radiation measuring device provided in this application, please refer to Figure 1 A plurality of positioning rods 2 are fixed along the circumference of the base 1, and the positioning rods 2 are arranged to be tilted downward. The plurality of positioning rods 2 are arranged along the circumference of the base 1, and the base 1 is stably supported by the cooperation of the plurality of positioning rods 2 to prevent the base 1 from tipping over.
