Description

Technical Field

[0001] The present application relates to the field of smoke detection equipment, and in particular to an auxiliary device for detecting particulate matter in exhaust gas emissions. Background Art

[0002] The particulate matter content in the exhaust gas emitted by the factory is an important indicator of the factory's exhaust gas emissions. Therefore, it is necessary to conduct regular inspections of the exhaust gas emitted by the factory to prevent the concentration of particulate matter in the exhaust gas from exceeding the standard.

[0003] The conventional detection method is to insert a detection gun into the exhaust gas for direct detection. The exhaust gas from the factory operation is collected through the exhaust gas pipeline and then transported to the industrial chimney for centralized discharge. Therefore, directly detecting the exhaust gas discharged from the industrial chimney can more intuitively reflect the overall exhaust gas emission status of the factory.

[0004] Usually, an inspection port is opened on the middle side wall of an industrial chimney. During inspection, inspectors need to climb up the ladder on the side wall of the chimney to the middle of the chimney, and then insert the tip of the inspection gun through the inspection port into the chimney for inspection. However, since industrial chimneys are generally high, inspectors who climb to the inspection port in the middle of the industrial chimney for inspection face great safety risks during their work. Summary of the invention

[0005] In order to solve the problem that inspectors who climb to the inspection port in the middle of an industrial chimney for inspection face great safety risks while working, the present application provides an auxiliary device for detecting particulate matter in exhaust gas emissions.

[0006] The exhaust gas emission particulate matter detection auxiliary device provided in this application adopts the following technical solution:

[0007] An auxiliary device for detecting exhaust gas emission particulate matter comprises a mounting frame, on which a detection mechanism for detecting exhaust gas is arranged, a pull rod is slidably mounted on the mounting frame, a first fixing mechanism is arranged on the pull rod, the mounting frame is provided with a driving mechanism for driving the pull rod to slide, and a second fixing mechanism is arranged on the mounting frame, and both the first fixing mechanism and the second fixing mechanism are used to fix the mounting frame on an industrial chimney.

[0008] By adopting the above technical solution, when conducting inspection, the mounting frame is first fixed to the side wall of the chimney by the second fixing mechanism and the pull rod is vertical, then the driving mechanism is started to drive the pull rod to extend upward, and when the pull rod is extended to the upper limit, the first fixing mechanism is started to fix the pull rod and the chimney, and then the second fixing mechanism is separated from the chimney, and the driving mechanism is started to drive the pull rod to contract and drive the mounting frame to rise upward, and the above movement is repeated to lift the mounting frame to the inspection port of the chimney and then stop, and the smoke at the inspection port of the chimney is inspected by the inspection mechanism. Since the mounting frame is lifted to the smoke exhaust port of the chimney through the cooperation between the pull rod and the first fixing mechanism and the second fixing mechanism, there is no need for the inspector to climb to a higher position during inspection, thereby reducing the safety hazard that the inspector may fall from the chimney when inspecting the exhaust gas in the chimney.

[0009] Optionally, the first fixing mechanism includes a rotating shaft rotatably mounted on the pull rod, first fixing rods are slidably mounted on both ends of the rotating shaft, friction rollers are provided on the end of the first fixing rod away from the rotating shaft, the two friction rollers extend towards each other, a first driving member for driving the first fixing rod to slide is provided on the rotating shaft, the first fixing rod is circumferentially fixed to the rotating shaft, and a friction motor for driving the rotating shaft to rotate is provided on the pull rod.

[0010] By adopting the above technical solution, after the two first fixed rods and the two friction rollers surround the chimney, when the pull rod rises to the limit height, the friction motor drives the rotating shaft to rotate until the friction rollers are pressed against the side walls of the chimney, and then the mounting frame is hung on the chimney through the cooperation between the friction rollers and the two first fixed rods. Since the side walls of common industrial chimneys are inclined, and the gravity of the mounting frame is transmitted through the inclined first fixed rods, there will be a component force that presses the friction rollers against the side walls of the chimney, so that the mounting frame is not easy to slide after being suspended on the chimney through the first fixed rods and the friction rods.

[0011] Optionally, the first driving member includes a spring sleeved on two ends of the rotating shaft and a limit plate threadedly mounted on the two ends of the rotating shaft, the first driving member also includes two limit bars slidably mounted on the rotating shaft, the length direction of the limit bar is parallel to the axis of the rotating shaft, the limit bar slides along the axis direction of the rotating shaft, the two limit bars are respectively connected to the two first fixing rods, the limit bars are respectively provided with a plurality of latching teeth at intervals along their length direction, the limit bars are rotatably mounted on both ends of the rotating shaft, the stop gear and the latching teeth are mutually meshed, and a clamping plate is also rotatably mounted on both ends of the rotating shaft, and a coil spring is provided at the rotating connection between the clamping plate and the rotating shaft, the coil spring pushes the clamping plate to press against the side wall of the stop gear tooth, and when the two limit bars are displaced toward each other, the rotation direction of the stop gear is forward, and the clamping plate is used to stop the stop gear from reversing.

[0012] By adopting the above technical solution, the spring is used to push the first fixed rod to slide, and at the same time the first fixed rod is circumferentially fixed on the rotating shaft through the limit bar. Due to the cooperation between the stop gear, the locking teeth on the limit bar and the clamping plate, the two limit bars are not easy to slide back to back, and then the two first fixed rods are not easy to slide back to back, which further improves the stability of the mounting frame when it is suspended by the first fixed rod and the friction roller.

[0013] Optionally, the second fixing mechanism includes a connecting rod installed on the mounting frame, a second fixing rod is provided on one end of the connecting rod, two fixing plates are slidably installed on the second fixing rod, rubber layers are laid on opposite sides of the two fixing plates, a reverse threaded rod is rotatably installed on the second fixing rod, two ends of the reverse threaded rod respectively pass through the two fixing plates and are threadedly matched with the fixing plates, a driving motor is provided on the second fixing rod, and the driving motor is transmission-connected to the reverse threaded rod.

[0014] By adopting the above technical solution, before testing, the chimney is first surrounded by two fixing plates. When the mounting frame is lifted by the pull rod, the driving motor is started to drive the reverse threaded rod to rotate, thereby driving the fixing plate to clamp the chimney. Since the chimney is inclined, the gap between the fixing plate and the side wall of the chimney is compensated by the rubber layer.

[0015] Optionally, an arc groove is provided on the top wall of the second fixing rod, and the plane where the arc line of the arc groove lies is horizontal. The end of the connecting rod away from the mounting frame is slidably installed in the arc groove, and the second fixing rod is provided with a second driving member for driving the connecting rod to slide along the arc groove.

[0016] By adopting the above technical solution, when the mounting frame is lifted to the detection port of the chimney, there is a deviation in the relative position between the detection mechanism on the mounting frame and the detection port for detecting the chimney. The mounting frame adjusts the position of the detection mechanism by sliding the connecting rod in the arc groove, so that the detection mechanism corresponds to the detection port, thereby reducing the difficulty of calibrating the position of the mounting frame during detection.

[0017] Optionally, the second driving member includes a sliding motor mounted on the second fixed rod, and two wire wheels are coaxially mounted on the second fixed rod. The output shaft of the sliding motor is coaxially connected to the two wire wheels. Pull ropes are wound around the two wire wheels, and the winding directions of the pull ropes on the two wire wheels are opposite. One ends of the two pull ropes are respectively inserted into the arc groove from both ends of the arc groove, and one ends of the two pull ropes are respectively connected to the opposite side walls of the pull rod.

[0018] By adopting the above technical solution, since the pull ropes on the two reels are wound in opposite directions, when the sliding motor drives the two reels to rotate synchronously, the reels drive the arc block to slide through the pull ropes, so that the arc block is more stable when sliding.

[0019] Optionally, the cross-section of the arc groove is dovetail-shaped, an arc block is slidably installed in the arc groove, the arc block is connected to the connecting rod, and a plurality of balls are rollingly installed on the three surfaces of the arc block and the arc groove, and the balls are tightly pressed against the side walls of the arc groove.

[0020] By adopting the above technical solution, the arc block is supported by the ball bearings when sliding, so that the arc block and the arc groove slide through the ball bearings, and the arc block is not prone to getting stuck when sliding.

[0021] Optionally, the detection mechanism includes a bracket vertically slidably mounted on the mounting frame, a mounting seat is mounted on the bracket for radial sliding movement along the chimney, a detection gun is rotatably mounted on the mounting seat, the rotation center of the detection gun coincides with its axis, the detection end of the detection gun faces the chimney, a third driving member for driving the detection gun to rotate is provided on the mounting seat, a sealing block for sealing the chimney detection port is provided on the end of the mounting seat facing the chimney, the mounting frame is provided with a first power member for driving the bracket to slide, the bracket is provided with a second power member for driving the mounting seat to slide, and the mounting frame is provided with a camera for observing the chimney.

[0022] By adopting the above technical solution, the inspector observes the condition of the chimney through a camera, and then adjusts the height of the bracket so that the inspection gun is facing the inspection port of the chimney. The sliding mounting seat then inserts the gun head of the inspection gun into the chimney for inspection. At this time, the sealing block blocks the inspection port, making it difficult for the inside of the chimney to leak from the inspection port. When the inspection of the inspection gun is completed, the inspection gun is driven to rotate 180° by the third driving member, so that the particulate matter collected by the inspection gun is not easy to fall from the inspection part of the inspection gun.

[0023] Optionally, a mounting box is provided on the mounting frame, and an opening is provided at one end of the mounting box facing the chimney, a slider is slidably installed in the mounting box along the opening, the camera is installed on the slider, a second screw rod is rotatably installed in the mounting box, one end of the second screw rod passes through the slider and cooperates with the slider thread, a camera motor is also provided in the mounting box and is transmission-connected to the second screw rod, a cover for closing the opening is rotatably installed on the mounting box, a coil spring is also provided at the connection between the cover and the mounting box, and the coil spring pushes the cover to close the opening.

[0024] By adopting the above technical solution, since the camera may be disturbed by the impact of birds at high altitudes, and the discharge from the detection port in the chimney for chimney detection may cause contamination and corrosion to the camera lens, which will reduce the life of the camera, after the detection gun performs detection, the camera motor is started to drive the slider to slide and retract the camera into the installation box, and the cover closes the opening under the action of the coil spring to protect the camera. At the same time, when it is needed, the camera motor is started to drive the slider and the camera to slide, so that the camera end of the camera extends through the opening to the outside world for shooting.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When conducting the inspection, first fix the mounting frame on the side wall of the chimney through the second fixing mechanism and the pull rod is vertical, then start the driving mechanism to drive the pull rod to extend upward, and when the pull rod is extended to the upper limit, start the first fixing mechanism to fix the pull rod and the chimney, and then separate the second fixing mechanism from the chimney, start the driving mechanism to drive the pull rod to contract and drive the mounting frame to rise upward, repeat the above movement to lift the mounting frame to the smoke exhaust port of the chimney and then stop, and detect the smoke at the smoke exhaust port of the chimney through the detection mechanism. Since the mounting frame is lifted to the smoke exhaust port of the chimney through the cooperation between the pull rod and the first fixing mechanism and the second fixing mechanism, it is not necessary for the inspection personnel to climb to a higher position during the inspection, thereby reducing the safety hazard of the inspection personnel when inspecting the exhaust gas discharged from the chimney;

[0027] 2. When the mounting frame is lifted to the upper end of the chimney, there is a deviation in the relative position between the detection mechanism on the mounting frame and the detection port of the chimney. The mounting frame adjusts the position of the detection mechanism by sliding the connecting rod in the arc groove, so that the detection mechanism corresponds to the detection port, reducing the difficulty of calibrating the position of the mounting frame during detection;

[0028] 3. Since the camera may be disturbed by the impact of birds at high altitudes, and the discharge from the detection port in the chimney may cause contamination and corrosion to the camera lens, which will reduce the life of the camera, after the detection gun is used for detection, the camera motor is started to drive the slider to slide and retract the camera into the installation box. The cover closes the opening under the action of the coil spring to protect the camera. At the same time, when it is needed, the camera motor is started to drive the slider and the camera to slide, so that the camera end of the camera extends through the opening to the outside world for shooting.

The mounting frame 1 is provided with a driving mechanism 13 for driving the pull rod 11 to slide, and the driving mechanism 13 includes a vertical first screw rod 131. The upper end of the first screw rod 131 coaxially passes through the pull rod 11 and is threadedly matched with the pull rod 11. The mounting frame 1 is also fixedly installed with a lifting motor 132, and the output shaft of the lifting motor 132 is coaxially fixedly connected with the lower end of the first screw rod 131.

[0037] Reference Figure 1 The upper end of the pull rod 11 is provided with a first fixing mechanism 12, which includes a rotating shaft 121 rotatably mounted on the pull rod 11, and a friction motor 124 is fixedly mounted on the pull rod 11. The friction motor 124 is transmission-connected to the rotating shaft 121 through a bevel gear, and the rotating shaft 121 is driven to rotate by the friction motor 124. The rotating shaft 121 is horizontal and a first fixing rod 122 is provided on both ends of the rotating shaft 121, the axis of the first fixing rod 122 is perpendicular to the axis of the rotating shaft 121, and a connecting ring 1221 is integrally provided on one end of the first fixing rod 122, and the connecting ring 1221 is slidably sleeved on the rotating shaft 121.

[0038] Reference Figure 1 and Figure 2 , a first driving member 2 is arranged on the rotating shaft 121, and the first driving member 2 includes two limiting bars 23. A dovetail groove 1211 is provided on the side wall of the rotating shaft 121, and the length direction of the dovetail groove 1211 is parallel to the axis of the rotating shaft 121. The two limiting bars 23 are respectively slidably installed in the dovetail groove 1211. The facing ends of the two limiting bars 23 are respectively fixedly connected with two connecting rings 1221, and the first fixing rod 122 is circumferentially fixed to the rotating shaft 121 through the cooperation between the limiting bars 23 and the dovetail groove 1211. Two circular limiting plates 22 are threadedly installed at both ends of the rotating shaft 121, and a spring 21 is sleeved on the rotating shaft 121 between the limiting plate 22 and the connecting ring 1221.

When the two fixing rods and the rotating shaft 121 surround the chimney, the rotating shaft 121 is rotated to make the friction roller 123 press against the side wall of the chimney, and at the same time, the spring 21 pushes the first fixing rod 122 to press against the side wall of the chimney to limit the rotating shaft 121, and the rotating shaft 121 and the two first fixing rods 122 are fixed to the chimney by the friction force between the friction roller 123 and the chimney, and the mounting frame 1 is connected to the rotating shaft 121 by the pull rod 11, so that the mounting frame 1 is suspended on the chimney through the rotating shaft 121, the two first fixing rods 122 and the two friction rollers 123, and because the first fixing rods 122 are inclined, the gravity applied by the mounting frame 1 to the rotating shaft 121 is transmitted to the friction roller 123 through the first fixing rod 122, which will generate a component force toward the chimney direction, thereby making the friction force between the friction roller 123 and the chimney increase with the increase of the weight of the mounting frame 1, so that the mounting frame 1 can always be hung on the chimney more stably through the friction roller 123.

When the two limit bars 23 move toward each other, the rotation direction of the stop gear 25 is forward, and the clamping plate 26 is inclined toward the forward rotation direction of the stop gear 25 and presses against the side wall of the stop gear 25, so that the limit bar 23 is stopped from rotating in the reverse direction by the clamping plate 26, and then the two limit bars 23 and the two first fixed rods 122 are restricted from moving away from each other by the stop gear 25.

[0051] The implementation principle of an auxiliary device for detecting exhaust gas particles in the embodiment of the present application is as follows:

[0052] During inspection, the mounting frame 1 is first clamped and fixed on the chimney by two fixing plates 43, and then the clamping plate 26 is separated from the stop gear 25, and the two first fixing rods 122 are separated back to back. After the chimney is surrounded by the first fixing rod 122 and the friction roller 123, the clamping plate 26 and the first fixing rod 122 are released. The first fixing rod 122 presses against the side wall of the chimney under the action of the spring 21. After the pull rod 11 rises to the limit under the action of the lifting motor 132, the friction motor 124 drives the rotating shaft 121 to rotate until the friction roller 123 presses against the side wall of the chimney, and then the fixing plate 43 is separated from the chimney, and the lifting motor 132 lifts the mounting frame 1, and then the mounting frame 1 is transported to the upper end inspection port of the chimney by reciprocating motion.
