Specifically, a large gear 228 is fixedly mounted on the connecting pipe 206, the large gear 228 is fixedly connected with a small gear 229, the small gear 229 is fixedly mounted on an output shaft of the reversing motor 230, the reversing motor 230 is fixedly mounted inside a housing of the detecting mechanism 2, when the connecting pipe 206 is required to drive the air inlet pipe 201 to rotate, the reversing motor 230 is started to drive the small gear 229 to rotate, the large gear 228 is driven by the small gear 229 to rotate, and thus the connecting pipe 206 is driven by the large gear 228 to rotate around the first detecting pipe 202.

The main function is to determine whether the sealing performance is good or not by observing the relative position change of the first indicator plate 205 and the second indicator plate 210.
The intake pipe 201 is tapered in shape. When the air input increased, the speed that gas got into intake pipe 201 can be slowed down to conical intake pipe 201 to slow down the sliding speed of first detection stick 203, prevent to admit air at the excessive speed, lead to first detection stick 203 to slide too fast and cause the damage.
The bracket is fixedly installed on the background plate 227, and the background plate 227 is located on the same side of the first detection rod 203 and the second detection rod 208, and is parallel to the first detection rod 203 and the second detection rod 208. Since the sliding of the first and second detection sticks 203 and 208 must cause the position of the first and second indication plates 205 and 210 to be changed, the state of the sealability can be determined by comparing the position change between the first and second indication plates 205 and 210.
The first detecting component is provided with a signal emitting device, and when the pressure in the first detecting pipe 202 is increased, the signal emitting device gives an alarm.
Specifically, the signal transmitting device comprises a connecting cylinder 211, the connecting cylinder 211 is fixedly installed on the first detection tube 202, a rubber sheet 212 is fixedly installed inside the connecting cylinder 211 and made of flexible materials, a rack 213 is fixedly installed on the rubber sheet 212, the rack 213 is meshed with a gear 214, the rack 213 is slidably installed on a base 215, the gear 214 is rotatably installed on the base 215, the gear 214 is coaxially connected with a magnetic needle 217, an arc-shaped scale plate 216 is fixedly installed on the base 215, and a hall sensor is arranged on the arc-shaped scale plate 216.
A guard is also provided in the detection mechanism 2, and is mounted on the worm wheel 220 for preventing the first indicator panel 205 from being damaged.
Specifically, the protection device comprises a driving motor 218 fixedly mounted on a sliding seat 225, the sliding seat 225 is slidably mounted on a guide rod 226, the guide rod 226 is fixedly mounted on a housing, the housing is fixedly mounted on a mounting tube 1, an extension shaft of the driving motor 218 is fixedly mounted with a worm 219, the worm 219 is engaged with a worm gear 220 rotatably mounted on the sliding seat 225, one end of a rotating rod 221 is rotatably mounted on the worm gear 220, the other end of the rotating rod 221 is rotatably connected with a background plate 227, the background plate 227 is fixedly mounted inside the housing, a sliding rod 222 is rotatably mounted on the worm 219, a stopping rod 223 is slidably mounted on the sliding rod 222, a stopping spring 224 is sleeved on the outer ring of the stopping rod 223, one end of the stopping spring 224 is fixedly connected with the stopping rod 223, and the other end is fixedly connected with the sliding rod 222.
The working principle is as follows: the mounting pipe 1 is connected to an air inlet of the bag type dust collector, the small gear 229 is driven to rotate by the reversing motor 230, the small gear 229 drives the large gear 228 to rotate, the connecting pipe 206 is driven to rotate by the rotation of the large gear 228, and the air inlet on the air inlet pipe 201 faces the air flow direction, so that air can be conveniently fed. When the bag type dust collector is damaged in quality and air leakage occurs, more air needs to be sucked at the same time in order to ensure the air pressure balance in the dust collector, and thus, the air flowing through the detection mechanism 2 is increased.
When the gas flow rate and the gas flow rate are increased, the gas entering the gas inlet pipe 201 is increased, the gas flows into the connecting pipe 206 from the gas inlet pipe 201 and then enters the first detection pipe 202, the gas pressure of the first detection pipe 202 is increased, the pressure is larger than the elastic force of the first compression spring 204, the first detection rod 203 is pushed to slide in the first detection pipe 202, and at the moment, the first indicating plate 205 moves along with the first detection rod 203.
Meanwhile, since the container 207 is opened to the lower side and the flow direction of the wind is vertical and only one end is opened, when the flow rate of the wind is increased, the air balance inside the container 207 is broken, the air in the container 207 is pumped out, the pressure inside the container 207 is reduced, and the elastic force of the second compression spring 209 is greater than the air pressure, so that the second compression spring 209 pushes the second detection rod 208 to move to the side close to the container 207, and the second indicator board 210 moves along with the second detection rod 208.
The relative positions of the first indicator panel 205 and the second indicator panel 210 change as the first indicator panel and the second indicator panel move, and an operator may see through the transparent glass window of the housing to determine the hermeticity.
When the gas in the first detecting tube 202 is increased, the gas enters the connecting cylinder 211 from the first detecting tube 202, the gas pressure in the connecting cylinder 211 is increased, but because the edge of the rubber sheet 212 is fixed and flexible, the middle of the rubber sheet is bulged to one side of the rack 213, the rack 213 is pushed, the gear 214 is driven by the rack 213 to rotate, the magnetic needle 217 coaxial with the gear 214 rotates, and the signal is sent out through the Hall sensor on the arc-shaped scale plate 216 to inform an operator, and meanwhile, the signal is also transmitted to the driving motor 218.
The driving motor 218, which receives the signal, is activated to rotate the worm 219, and the worm wheel 220 is rotated by the worm 219, but since the rotating rod 221 cannot be extended, so that when the worm wheel 220 rotates, the worm wheel 220 is rotated and connected to the worm wheel 220 through the rotation rod 221, and the rotation rod 221 pulls the worm wheel 220, and the worm wheel 220 is rotatably mounted on the sliding seat 225, therefore, the sliding seat 225 will also slide while pulling the sliding rod 222 and the stopping rod 223 together until the stopping rod 223 contacts the first indicating plate 205, compressing the stopping spring 224, at which time the first indicating plate 205 stops sliding under the elastic force of the stopping spring 224 and the first compression spring 204, preventing the first indicating plate 205 from being damaged due to moving too far, the stopped first indicating plate 205 facing the scale position on the background plate 227, and the background plate 227 being used as a background, so that the positions of the first indicating plate 205 and the second indicating plate 210 can be more easily and visually seen.
When the gas outlet of the device to be detected needs to be detected, the installation pipe 1 is connected to the gas outlet, and meanwhile, the connecting pipe 206 is rotated to drive the gas inlet pipe 201, so that the gas inlet of the gas inlet pipe 201 faces the gas outlet direction of the gas outlet.
