[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a calibration device for a continuous emission monitoring system for flue gas, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a chimney body 1, an installation cylinder 2 fixedly connected to the side surface of the chimney body 1, an inspection hole on the chimney body 1, a connecting ring 3 movably connected to one side of the installation cylinder 2, an inspection probe 4 fixedly connected to the inner wall of the connecting ring 3, one end of the inspection probe 4 extending into the interior of the chimney body 1 through the inspection hole, an insert ring 5 fixedly connected to the side of the connecting ring 3 near the installation cylinder 2, a locking block 6 fixedly connected to the inner wall of the insert ring 5, a slot 7 adapted to the insert ring 5 being opened inside the installation cylinder 2, the insert ring 5 being inserted into the slot 7, a slot 8 being opened inside the installation cylinder 2, the slot 8 communicating with the slot 7, and the side surface of the locking block 6 fitting against the inner wall of the slot 8.

[0025] When using this device, the calibration probe 4 needs to be connected to the monitoring system. The calibration probe 4 can detect the values ​​of flue gas and feed them back to the monitoring system, thereby monitoring the flue gas emission in real time. The connecting ring 3 and the calibration probe 4 are an integral structure. When installing the calibration probe 4, first, the insertion ring 5 and the locking block 6 on the connecting ring 3 need to be aligned with the slot 7 and the groove 8 on the mounting cylinder 2. Then, move the connecting ring 3 so that the insertion ring 5 and the locking block 6 are inserted into the slot 7 and the groove 8 respectively. The groove 8 is L-shaped. When the locking block 6 comes into contact with the inner wall of the groove 8, the connecting ring 3 needs to be rotated so that the locking block 6 continues to move a distance inside the groove 8 until the locking block 6 comes into contact with the inner wall of the groove 8 a second time. At this time, the inner wall of the groove 8 will fix the locking block 6, thereby fixing the calibration probe 4, thus completing the installation of the calibration probe 4. When removing the calibration probe 4, simply rotate it in the opposite direction and pull the connecting ring 3 to remove the calibration probe 4 from the mounting cylinder 2.

[0026] Furthermore, to improve the stability of the calibration probe 4 when mounted on the mounting cylinder 2, such as... Figure 3 , Figure 4 and Figure 5 As shown, a fixed shell 11 is fixedly connected to the side surface of the mounting cylinder 2. An insert rod 12 is movably connected inside the fixed shell 11. The insert rod 12 passes through the fixed shell 11. An adjusting handle 14 is rotatably connected to one end of the insert rod 12. One side of the adjusting handle 14 is in contact with the side of the fixed shell 11 away from the mounting cylinder 2.

[0027] The mounting cylinder 2 has a through hole that is connected to the slot 7. The side surface of the insertion ring 5 has a socket that is compatible with the insertion rod 12. The end of the insertion rod 12 away from the adjusting handle 14 extends through the through hole into the interior of the slot 7 and is inserted into the socket.

[0028] The adjusting handle 14 can rotate 90 degrees on the fixed housing 11. When the operator turns the adjusting handle 14, the adjusting handle 14 can drive the connected insertion rod 12 to move. The insertion rod 12 will be in two states due to the pull of the adjusting handle 14. The first state is that the insertion rod 12 extends into the slot 7 through the through hole. The second state is that the insertion rod 12 retracts into the fixed housing 11 and the through hole.

[0029] When installing the calibration probe 4, firstly, the adjusting handle 14 needs to be turned so that the insertion rod 12 retracts into the fixed shell 11 and the through hole. Then, the insertion ring 5 and the locking block 6 on the connecting ring 3 are aligned with the slot 7 and the groove 8 on the mounting cylinder 2. Then, the connecting ring 3 is moved so that the insertion ring 5 and the locking block 6 are inserted into the slot 7 and the groove 8 respectively. When the locking block 6 comes into contact with the inner wall of the groove 8, the connecting ring 3 is rotated so that the locking block 6 continues to move a distance inside the groove 8 until the locking block 6 comes into contact with the inner wall of the groove 8 a second time. At this time, the insertion hole on the insertion ring 5 is also at the insertion rod 12. Then, by turning the adjusting handle 14, the adjusting handle 14 can drive the insertion rod 12 to move, so that the insertion rod 12 is inserted into the insertion hole, which improves the firmness of the calibration probe 4 installed on the mounting cylinder 2.

[0030] In order to improve the stability of the adjusting handle 14 during operation, such as Figure 3 , Figure 4 and Figure 5 As shown, a second spring 13 is sleeved on the side surface of the insertion rod 12. One end of the second spring 13 is fixedly connected to the insertion rod 12, and the other end of the second spring 13 is fixedly connected to the inside of the fixing shell 11.

[0031] The state of the insertion rod 12 is controlled by the adjusting handle 14. The second spring 13 can apply a pushing force to the insertion rod 12, thereby driving the adjusting handle 14 to press tightly against the fixed shell 11, which effectively improves the stability of the adjusting handle 14 and enables the adjusting handle 14 to better serve the insertion rod 12.

[0032] Furthermore, to facilitate the installation of calibration probe 4 by staff, such as... Figure 2 , Figure 3 and Figure 5 As shown, a pressure plate 9 is slidably connected inside the slot 7. The side surface of the pressure plate 9 is in contact with the inner wall of the slot 7. A first spring 10 is fixedly connected to one side of the pressure plate 9. The end of the first spring 10 away from the pressure plate 9 is fixedly connected to the inner wall of the slot 7.

[0033] The side of the pressure plate 9 away from the first spring 10 is in contact with the side of the insert ring 5 away from the connecting ring 3. Multiple first springs 10 are provided, and the multiple first springs 10 are distributed in a ring array.

[0034] When installing the calibration probe 4, the insertion ring 5 on the connecting ring 3 is inserted into the slot 7 on the mounting cylinder 2. During this process, the insertion ring 5 will come into contact with the pressure plate 9. As the insertion ring 5 continues to move, it will drive the pressure plate 9 to move inside the slot 7 and compress the first spring 10. The first spring 10 will also constantly apply a pushing force to the pressure plate 9. When the locking block 6 and the inner wall of the locking groove 8 make secondary contact, it is necessary to turn the adjusting handle 14 so that the insertion rod 12 is inserted into the insertion hole. At this time, due to the presence of the first spring 10, the pressure plate 9 will be pushed tightly against the insertion ring 5, thereby reducing the possibility of the insertion ring 5 rotating and causing the insertion hole and the insertion rod 12 to misalign, so as to ensure that the insertion rod 12 can be smoothly inserted into the insertion hole. The setting of multiple first springs 10 allows the pressure plate 9 to apply pressure evenly to the insertion ring 5, further reducing the possibility of the insertion ring 5 rotating.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
