Under the interference of the exhaust gas, it is inconvenient for the staff to repair the flow sensor, which will affect the overall work.
[0004] In view of this, a control device for a multi-channel flow average value test system is provided to overcome the above defects. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1
[0023] Referring to FIGS. 1-4 of the base, a control device for a multi-channel flow average value test system includes a base 1, a controller body 2, and an air outlet pipe 3. One end of the air outlet pipe 3 is fixedly connected with a retaining sleeve 5. An installation shaft 7 is fixedly installed at the middle position inside the retaining sleeve 5. A plurality of rotatable flow blocking blades 8 are installed on the outer wall of the installation shaft 7. One side of the flow blocking blade 8 is fixedly connected with a rotating column 9. The top end of the rotating column 9 is fixedly connected with a clamping groove 10. A rotating ring 12 is sleeved on the outer wall of the retaining sleeve 5. A plurality of push columns 11 are fixedly installed on the outer wall of the rotating ring 12. The number of the push columns 11 is multiple, and all the multiple push columns 11 are located inside the multiple clamping grooves 10.
[0024] Further, referring to Figure 4 , a limiting block 16 is fixedly installed on the outer wall of the retaining sleeve 5. A limiting groove is opened on the outer wall of the limiting block 16. The rotating ring 12 is located inside the limiting groove. By providing the limiting block 16, opening the limiting groove on the outer wall of the limiting block 16, and setting the rotating ring 12 to be located inside the limiting groove, the rotating ring 12 will not easily break away from the limiting block 16 during rotation.
[0025] It should be noted that the specific number of the limiting blocks 16 is three.
[0026] Even further, referring to Figure 4 , a mounting plate 15 is fixedly installed on the outer wall of the retaining sleeve 5. An electric telescopic rod 13 is fixedly installed on one side of the mounting plate 15. A push plate 14 is fixedly installed on the outer wall of the rotating ring 12. A square plate is fixedly installed at one end of the electric telescopic rod 13. A square groove is opened inside the push plate 14. The square plate is located inside the square groove. By providing the electric telescopic rod 13 and the square plate, and cooperating with the push plate 14 and the square groove, the electric telescopic rod 13 in the device pushes the square plate to move inside the square groove, thereby pushing the push plate 14 to move. Since the push plate 14 is fixedly installed on the outer wall of the rotating ring 12, the rotating ring 12 can be driven to rotate by the electric telescopic rod 13.
[0027] It should be noted that all the multiple electric telescopic rods 13 are electrically connected to the controller body 2, and the start and stop of the multiple electric telescopic rods 13 can be controlled by the controller body 2.
[0028] In addition, a flow sensor is installed inside the air outlet pipe 3.
[0029] During specific implementation, during the process of conventional multi-channel flow measurement, the flow sensor is continuously used, and various problems will inevitably occur. At this time, it is necessary for the staff to carry out maintenance. However, the continuous discharge of waste gas will hinder the maintenance work of the staff and also affect the normal operation of the device, causing the measured value of the average flow rate to deviate.
[0030] In this utility model, when the flow sensor in a certain air outlet pipe 3 fails, the user can control the electric telescopic rod 13 to start through the controller body 2. After the electric telescopic rod 13 starts, it moves through the square plate in the square groove. The volume of the square plate is small, so it can move inside the square groove. When the square plate initially contacts the inner wall of the square groove, the push plate 14 is driven to rotate. Therefore, although the square plate can only move horizontally, it can still push the 14 to move a short distance. After the push plate 14 rotates, it drives the rotating ring 12 to rotate. Because the rotation distance is short, the push of the electric telescopic rod 13 can drive the rotating ring 12 to rotate. During the rotation of the rotating ring 12, multiple push columns 11 move in the clamping groove 10, and the clamping groove 10 is fixedly connected to one end of the rotating column 9. Therefore, after the push column 11 moves, the clamping groove 10 cannot move and can only rotate, and the rotating column 9 is fixedly connected to the baffle blade 8. The baffle blade 8 is rotatably installed on the outer wall of the installation shaft 7. Therefore, after the push column 11 moves in the clamping groove 10, it drives the baffle blade 8 and the rotating column 9 to rotate together. After multiple baffle blades 8 rotate to the horizontal state, one end of the air outlet pipe 3 can be blocked to prevent a large amount of waste gas from entering the air outlet pipe 3 from the retaining sleeve 5. At this time, the relevant staff can easily complete the maintenance work of the flow sensor in the air outlet pipe 3.
[0031] By setting the baffle blade 8, rotating column 9, clamping groove 10, push column 11 and rotating ring 12, the baffle blade 8 can block most of the space in the retaining sleeve 5 to prevent waste gas from entering the air outlet pipe 3 through the retaining sleeve 5, enabling the staff to easily complete the maintenance work of the flow sensor in the air outlet pipe 3.
[0032] At the same time, by adjusting the rotation angle of the baffle blade 8, the flow rate of the waste gas in the retaining sleeve 5 can also be controlled, so that the discharge speed of the waste gas in multiple air outlet pipes 3 can be controlled, preventing the subsequent waste gas treatment device from being easily unable to handle the waste gas in time and preventing the waste gas from overly affecting the work.
[0033] It should be noted that an air outlet 4 is provided on one side of the air outlet pipe 3, and an air inlet 6 is provided on one side of the retaining sleeve 5.
[0034] Working principle: During the process of conventional multi-channel flow testing, the flow sensor is continuously used, and various problems are inevitable. At this time, it is necessary for the staff to carry out maintenance. However, the continuous discharge of waste gas will hinder the maintenance work of the staff and affect the normal operation of the device, resulting in deviation in the measured value of the average flow rate.
[0035] In this utility model, when the flow sensor in a certain air outlet pipe 3 fails, the user can control the electric telescopic rod 13 to start through the controller body 2. After the electric telescopic rod 13 starts, it moves in the square groove through the square plate, thereby pushing the push plate 14 and driving the rotating ring 12 to rotate. Because the rotation distance is short, the push of the electric telescopic rod 13 can drive the rotating ring 12 to rotate. During the rotation of the rotating ring 12, multiple push columns 11 move in the clamping groove 10, and the clamping groove 10 is fixedly connected to one end of the rotating column 9. Therefore, after the push column 11 moves, the clamping groove 10 cannot move and can only rotate, and the rotating column 9 is fixedly connected to the baffle blade 8. The baffle blade 8 is rotatably installed on the outer wall of the installation shaft 7. Therefore, after the push column 11 moves in the clamping groove 10, it will drive the baffle blade 8 and the rotating column 9 to rotate together. After multiple baffle blades 8 rotate to the horizontal state, one end of the air outlet pipe 3 can be blocked to prevent a large amount of waste gas from entering the air outlet pipe 3 from the retaining sleeve 5. At this time, the relevant staff can easily complete the maintenance work on the flow sensor in the air outlet pipe 3.
[0036] By setting the baffle blade 8, the rotating column 9, the clamping groove 10, the push column 11 and the rotating ring 12, the baffle blade 8 can block most of the space in the retaining sleeve 5 to prevent waste gas from entering the air outlet pipe 3 through the retaining sleeve 5, enabling the staff to easily complete the maintenance work on the flow sensor in the air outlet pipe 3.
[0037] By adjusting the rotation angle of the baffle blade 8, the flow rate of the waste gas in the retaining sleeve 5 can also be controlled, so that the discharge speed of the waste gas in multiple air outlet pipes 3 can be controlled, preventing the subsequent waste gas treatment device from being easily unable to handle the waste gas in time and preventing the waste gas from overly affecting the work.
