Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-2, a detecting device for electromechanical equipment on a highway comprises a pipe body 1, wherein a fan embedded groove 2 is formed in the inner wall of the pipe body 1, a detecting pipe 5 is arranged in the pipe body 1, and a digital micro-pressure meter 6 is arranged on the detecting pipe 5.
Dust screen 3 is installed to body 1's air intake department, bar groove 31 has been seted up to dust screen 3's lateral wall, the embedded reed 4 that shakes that is equipped with of bar groove 31, and shake reed 4's both ends all with two inner wall fixed connection of bar groove 31, body 1's lateral wall has been seted up and has been put thing groove 9, it is equipped with sleeve 10 in the thing groove 9 to put, the embedded power generation piece 11 that is equipped with of sleeve 10, power generation piece 11 adopts piezoceramics material to make, and power generation piece 11 passes through electric capacity and 4 electric connection of reed that shakes, arc 7 has been seted up to body 1's inner wall, install the vibrating device who makes power generation piece 11 vibrate in the arc.
The vibrating device comprises a wind wheel 8 which is rotatably connected in an arc-shaped groove 7, one blade of the wind wheel 8 is made of a magnetic material, a sliding block 12 made of iron is connected in a sleeve 10 in a sliding mode, the sliding block 12 is elastically connected to the inner wall of the sleeve 10 through a spring 13, the sleeve 10 is made of a rubber material, and fur is fixedly connected to the side wall of the sliding block 12.
It should be noted that, as shown in fig. 2, the size of the sliding block 12 is small, on one hand, the sliding block 12 can be ensured to move back and forth under the combined action of the magnetic blades of the wind wheel 8 and the spring 13, and on the other hand, referring to fig. 2, only the upper end of the sliding block 12 is in contact with the inner top of the sleeve 10, so that the generated static electricity is ensured to be concentrated above the sleeve 10 and is close to the dust filter 3, and shaken-off impurities can be efficiently and firmly adsorbed on the sleeve 10.
When the device is used, a fan to be detected is placed into the fan embedded groove 2, the fan is started, air flows in the pipe body 1 at a high speed and flows through the detection pipe 5 after being filtered by the dust filtering net 3, and the digital micro-pressure meter 6 can detect the ventilation volume in the pipe body 1.
In the process, the air flow pushes the wind wheel 8 to rotate circularly, and the magnetic blades of the wind wheel 8 rotate along with the wind wheel and are continuously close to and away from the iron sliding block 12. As shown in fig. 2, each time the magnetic blade approaches the slider 12, the magnetic force between the two is greater than the elastic force of the spring 13, so the slider 12 will move to the right, and when the magnetic blade moves away from the slider 12, the magnetic force between the two is less than the elastic force of the spring 13, the slider 12 will move to the left and hit the primary power generating piece 11, forcing the power generating piece 11 to vibrate. Therefore, in the circulating rotation process of the wind wheel 8, the sliding block 12 continuously moves left and right to and fro and continuously collides with the electricity triggering sheet 11, the electricity generating sheet 11 made of piezoelectric ceramics continuously vibrates and accumulates a large amount of static electricity at two ends of the electricity generating sheet, when the accumulated charge reaches a certain amount, the capacitor can be punctured and the vibrating spring 4 is electrified, the vibrating spring 4 contracts after being electrified, the capacitor recovery circuit is also disconnected after the accumulated static electricity is lost, and the vibrating spring 4 is stretched and recovered under the action of self elasticity after being powered off. So can make the reed 4 that shakes stretch out and draw back constantly to arouse that the dirt filtrating screen 3 constantly shakes, can shake off attached to the impurity on the dirt filtrating screen 3 fast, thereby keep the good permeability of dirt filtrating screen 3, guarantee that the air volume in the body 1 is unanimous with the intake of fan, improve the detection precision of the fan amount of wind greatly. It is worth mentioning in addition that the continuously jittering dust filter net 3 can also make impurities difficult to attach to the dust filter net 3, so that the device also has a good dustproof effect.
Meanwhile, as shown in fig. 2, in the process that the slider 12 moves back and forth left and right, fur on the slider 12 continuously rubs against the upper inner wall of the rubber sleeve 10, so that a large amount of static charge can be generated above the sleeve 10, and the impurities are shaken off and attracted by the electrostatic force to be adsorbed above the sleeve 10 because of the small volume of the impurities. So can prevent that the impurity after trembling from rising along with the air current, adhere to again on the outer wall of dirt screen 3, strengthen this device's dustproof effect, further improve the detection precision to the fan amount of wind.
Example two:
referring to fig. 3-5, different from the first embodiment, the sleeve 10 is rotatably connected in the storage tank 9 through a damping rotating shaft, a plurality of dust storage tanks 101 are disposed on the circumferential side wall of the sleeve 10 at equal intervals, and the grounding pole 14 is mounted at the inner bottom of the storage tank 9.
It should be noted that the sleeve 10 is rotatably connected in the storage tank 9 through the damping rotating shaft, so that the sleeve 10 does not rotate under the condition of no external force or small external force, on one hand, the sleeve 10 cannot rotate to cause insufficient static electricity and difficult impurity adsorption in the process of moving back and forth by the sliding block 12 in the sleeve 10, and on the other hand, sufficient impurities can be stored in the dust storage tank 101 to rotate again, so that the impurities can be gathered into a group when falling, the whole body is strong in gravity action, and cannot be reattached to the outer wall of the dust filter 3 along with the rising of the air flow.
Furthermore, because the generated static electricity is always gathered above the sleeve 10, and the sleeve 10 is made of rubber insulating material, when the sleeve 10 does not rotate, the static electricity above the sleeve 10 is difficult to be transmitted to the ground through the grounding post 14, so the use of the original function of the device is not influenced.
When the amount of the impurities adsorbed on the sleeve 10 is too large, the subsequent adsorption of the impurities is affected. In the present embodiment, the impurities are shaken off the dust filter 3 and fall into the dust storage groove 101, and as shown in fig. 5, since the dust storage groove 101 at the left side of the sleeve 10 is close to the dust filter 3, a large amount of impurities are shaken off and fall into the dust storage groove 101. Along with the impurity in the dust storage tank 101 of this side is more accumulated more, can overcome the frictional resistance of damping pivot and promote sleeve 10 anticlockwise rotation at last, so can be with storing the dust storage tank 101 of impurity vertically downwards, the last lateral wall of sleeve 10 rotates the below and contacts with ground connection post 14 simultaneously, can lead the static electricity on the sleeve 10 to ground, the impurity in the dust storage tank 101 can rely on the dead weight to fall down.
After the sleeve 10 rotates, an empty dust storage groove 101 can be close to the dust filter 3, shaken-off impurities are received, and the sleeve 10 can be pushed to rotate anticlockwise again after sufficient impurities are received, so that the dust storage groove 101 in the sleeve 10 can continuously and efficiently receive the impurities.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
