DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following will further describe the utility model in combination with specific figures.

[0024] As Figure 1 And Figure 2As shown, the existing smoke damper actuator includes a base 11 mounted on the valve body 1, a rotating shaft connected with the valve plate 12 is rotatably connected inside the valve body 1, one end of the rotating shaft extends to the inside of the base 11 and is connected with a ratchet lock disc 14 through a torsional spring 13, a locking rod 15 is rotatably connected to the base 11 through a connecting column 16, one end of the locking rod 15 is provided with a ratchet corresponding to the ratchet lock disc 14, when the locking rod 15 oscillates around the connecting column 16 to make the ratchet disengage from the ratchet lock disc 14, the rotating shaft and the ratchet lock disc 14 are driven to rotate under the action of the torsional spring 13, thereby closing the valve plate 12 in the valve body 1, and when the ratchet lock disc 14 is reversely rotated, such as reversely rotating the ratchet lock disc 14 outside the actuator through a special tool, the valve plate 12 can be reset, and the valve plate 12 is closed in the following three ways, the first is that one end of the locking rod 15 is connected with a pull rod or connecting rope 101, the locking rod 15 is oscillated by pulling, the second is that one end of the locking rod 15 is hingedly connected with one end of an electromagnet 102, the locking rod 15 is oscillated around the connecting column 16 by the attraction of the electromagnet 102 after being electrified, and the third way is that a fusible metal 103 is mounted on the base 11, one end of the fusible metal 103 extends into the valve body 1, a connecting plate 104 is connected between the locking rod 15 and the fusible metal 103, and the connecting plate 104 is connected with the base 11 through an elastic member 105, when the heat in the pipeline reaches a certain temperature to make the fusible metal 103 break, the fusible metal 103 is disconnected from the connecting plate 104, thereby pulling the connecting plate 104 and the locking rod 15 to oscillate under the action of the elastic member 105, the above several ways are to oscillate the locking rod 15 to open and close the valve plate 12, and the above are all prior art, and those skilled in the art should know that they will not be described in detail here, and at present, when the actuator is detected, the detection frequency is about 50 times, which is also detected by manually opening and resetting, the efficiency is low, and the detection frequency is less than the number of times that may not be sufficient to fully expose the problems of the actuator, therefore, the present scheme is improved as follows:

[0025] As shown in the accompanying drawings, Figures 1-7 A smoke damper actuator detection test device, a driving member 3 is provided at the upper end of the actuator through a mounting frame 2, wherein the driving member 3 can be a reduction motor or the like, the output end of the driving member 3 is connected with a rotating disc 31, further comprising a closing assembly and a resetting assembly to close and reset the valve plate 12;

[0026] Specifically, as shown in the accompanying drawings, Figures 3-4As shown, the closing assembly includes a swing arm 33 connected to the turntable 31 via a connecting rod 32. The swing arm 33 can be made of a material with a certain degree of toughness. When the drive member 3 drives the swing arm 33 to move, the swing arm 33 can abut against the locking rod 15 in the actuator, causing the locking rod 15 to swing around the connecting post 16 and disengage from the ratchet locking disc 14. Under the action of the torsion spring 13, the ratchet locking disc 14 will drive the connecting shaft to rotate to close the valve plate 12. When the end of the locking rod 15 away from the ratchet locking disc 14 swings at a certain angle and can no longer swing, as the turntable 31 drives the swing arm 33 to move continuously, the swing arm 33 will bend to a certain extent and disengage from the abutment of the locking rod 15.

[0027] The reset assembly includes an abutment rod 4 mounted on the ratchet locking disc 14 within the actuator, a telescopic member 42 mounted on the connecting rod 32 via a connecting seat 41, a controller 43 electrically connected to the telescopic member 42, and a first pressure sensor 44 electrically connected to the controller 43. The telescopic member 42 can be an electric telescopic rod or similar device. The first pressure sensor 44 is connected to the lower part of the mounting bracket 2 via a mounting member 5. When the torsion spring 13 drives the ratchet locking disc 14 to rotate, it will drive the abutment rod 4 to rotate synchronously, and the abutment rod 4 will exert pressure on the first pressure sensor 44. The pressure signal is transmitted to the controller 43. The controller 43 controls the telescopic member 42 to move downward. As the drive member 3 drives the turntable 31 to move continuously, when the connecting rod 32 rotates to the position of the contact rod 4, the telescopic member 42, after moving downward, will come into contact with the contact rod 4. This will cause the ratchet locking disc 14 to reset and rotate through the contact rod 4, thus opening the valve plate 12. In order for the telescopic member 42 to come into contact with the contact rod 4 more stably, a pusher 45 is connected to the movable end of the telescopic member 42, which can be locked on the outer wall of the contact rod 4.

[0028] Furthermore, such as Figures 4-7 As shown, in order to release the contact force of the telescopic member 42 on the abutment rod 4 when the ratchet locking disc 14 is reset to a certain extent, an angle sensor 6 electrically connected to the controller 43 is also provided on the turntable 31. If the turntable 31 and the ratchet locking disc 14 are detected to rotate to a certain angle, the angle sensor 6 transmits a signal to the controller 43. The controller 43 controls the telescopic member 42 to move upward to release the contact with the abutment rod 4, so that the turntable 31 can rotate again to perform the next cycle of detection without being affected.

[0029] Furthermore, such as Figure 7As shown, the end of the mounting component 5 has a sliding cavity 51. The first pressure sensor 44 is installed inside the sliding cavity 51, and the sliding cavity 51 is slidably connected to the contact frame 52. A spring 53 is connected between the contact frame 52 and the sliding cavity 51. When the locking rod 15 swings and releases its contact with the ratchet locking disc 14, the ratchet locking disc 14 drives the contact rod 4 to rotate under the action of the torsion spring 13. The torque is relatively large. At this time, the contact rod 4 will first compress the spring 53 through the contact frame 52 and be buffered by the spring 53. Then the end of the contact rod 4 will contact the first pressure sensor 44, thereby causing the first pressure sensor 44 to generate a pressure signal.

[0030] Among them, such as Figure 3 As shown, it also includes a warning component, which includes a buzzer 7 and a second pressure sensor 71. The second pressure sensor 71 is mounted on the swing arm 33. When the swing arm 33 contacts the locking rod 15, the second pressure sensor 71 generates a pressure signal and transmits it to the controller 43. If the locking rod 15 swings off and contacts the ratchet locking disc 14, the ratchet locking disc 14 generates another pressure signal to the first pressure sensor 44 through the contact rod 4. At this time, the controller 43 receives two pressure signals, indicating that it is normal. If the ratchet locking disc 14 does not drive the contact rod 4 to generate a pressure signal to the first pressure sensor 44, the controller 43 only receives one pressure signal, which will be judged as abnormal, thereby controlling the buzzer 7 to issue a warning prompt so as to remind personnel to check in time.

[0031] Furthermore, the connecting rod 32 is a telescopic structure, and the connecting seat 41 is installed on the fixed end of the connecting rod 32. The length of the connecting rod 32 can be adjusted according to the length of the locking rod 15, so that the connecting rod 32 can drive the swing arm 33 to come into contact with the end of the locking rod 15 away from the ratchet locking disc 14, making it easier to push the locking rod 15.

[0032] Furthermore, the contact rod 4 and the ratchet locking disc 14 are detachably connected, such as by snap-fit ​​or threaded connection. During production, a slot for mounting the contact rod 4 can be opened on the ratchet locking disc 14. After testing, the contact rod 4 can be removed from the ratchet locking disc 14 for reuse, which can also reduce the weight of the actuator.

[0033] Furthermore, such as Figure 6 As shown, mounting bracket 2 has mounting grooves 21 on both sides, and locking bolts 22 are threadedly connected to both sides of mounting bracket 2. The mounting bracket 2 is fixed to the actuator base 11 by mounting grooves 21 and by rotating locking bolts 22, which makes it easier to carry out testing and inspection of the actuator.

[0034] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
