Embodiment
Below embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1 to 5, the utility model provides one and to remove contamination sensor, and comprise sensing unit 20, sensing unit comprises: the first fixed block 1; Two tongue tubes 2, are arranged on the first fixed block 1; Sliding shoe 3, is arranged on the side of the first fixed block 1 actively; Magnetic element 4, is arranged on sliding shoe 3; By pulling block 5, be connected with sliding shoe 3; And blade assembly, be arranged on the both sides of the first fixed block 1 symmetrically,
be connected with the side by pulling block 5 respectively.Preferably, tongue tube 2 is arranged on transverse slat 10.Especially, the number of tongue tube 2 is two, and magnetic element 4, between these two tongue tubes 2, like this, when magnetic element 4 moves to corresponding tongue tube 2 to the direction of any one tongue tube 2, namely can produce corresponding signal.
When there is no dirt in current, by blade assembly stressed substantially equal of pulling block 5 both sides, so remain on initial equilibrium position by pulling block 5, now, magnetic element 4 on sliding shoe 3 also remains on predetermined relative position with tongue tube 2, now, tongue tube 2 produces the first signal, to show in current without dirt.When there being dirt in current, by pulling block 5 both sides blade assembly stressed not etc., so depart from initial equilibrium position by pulling block 5, now, magnetic element 4 on sliding shoe 3 relatively tongue tube 2 moves, thus makes tongue tube 2 produce secondary signal, to show there is dirt in current.So the equipment such as trash, just can to remove contamination accordingly work according to the first signal and secondary signal, thus effectively can control the duty of trash, high efficiency work.Such as, when having dirt, make its automatic operation, clean out and automatically stop standby, energy-conserving and environment-protective, decrease wear and tear in machines, extend the serviceable life of equipment.
Preferably, sensor of removing contamination also comprises the second fixed block 7, is arranged on the side away from sliding shoe 3 by pulling block 5, and the second fixed block 7 is provided with holding recess part 8, by pulling block 5 being provided with the projection 9 coordinated with holding recess part 8.Like this, when equilibrium position, projection 9 is embedded in holding recess part 8, plays the effect of location, prevents error signal.When both sides blade assembly occur unbalanced stressed time, under this force, projection 9 pull out from holding recess part 8, thus drive be subject to pulling block 5 move.Such as, this projection 9 can be roller etc.
In one embodiment, sliding shoe 3 has the cross section of E shape, thus forms two draw-in grooves; Then there is by pulling block 5 cross section of π shape, thus form two juts.These two juts, when the projection 9 of sliding shoe 3 departs from holding recess part 8, are inserted in above-mentioned two draw-in grooves, thus sliding shoe 3 is engaged with by pulling block 5, and together move.
Preferably, be connected with sliding shoe 3 by spring 6 by pulling block 5.Can making to flexibly connect by producing between pulling block 5 and sliding shoe 3 by spring 6, the more important thing is, when reverting to equilibrium position by pulling block 5, projection 9 can be pushed in holding recess part 8 again.
Preferably, the first fixed block 1 has mutual transverse slat connected vertically 10 and riser 11, riser 11 is provided with the teat 12 contacted with sliding shoe 3.Like this, sliding shoe 3 is positioned at the below of riser 11, and its facade towards transverse slat 10 is contacted with transverse slat 10 by teat 12, thus friction force when reducing slip.
Preferably, blade assembly is connected with by pulling block 5 by stay cord 13.Preferably, blade assembly comprises pull bar 15 and blade 16, and one end of pull bar 15 is connected with shell 14 pivotly by pivot pin 18, and the other end of pull bar 15 is fixedly connected with blade 16.
Preferably, the number by pulling block 5 is multiple, and multiple pulling block 5 that is subject to is arranged abreast.Like this, when any one is subject to pulling block 5 when pulled, all corresponding signal can be generated.
Preferably, sensor of removing contamination also comprises shell 14, and one end of blade assembly is connected pivotly with shell 14, and sensing unit is arranged on shell 14.Preferably, shell 14 has oval cross section, thus, can reduce the resistance of water.
Preferably, sensor of removing contamination also comprises back-moving spring 19, and the two ends of sliding shoe 3 are separately installed with a back-moving spring 19, are returned to initial equilibrium position to make sliding shoe 3.
Please refer to Fig. 6, the utility model additionally provides a kind of trash, comprises trash rack, the grizzly bar 17 of trash rack is provided with the sensor 21 of removing contamination that at least one is above-mentioned.Especially, in rotary type trash cleaning device, similarly sensor of removing contamination can be placed on the back side of grizzly bar, and multiple sensor of removing contamination can be placed, to control clean-up operation efficiently according to the size of trash rack.
Please refer to Fig. 5, wherein, arrow is depicted as water (flow) direction.During use, after trash rack, load onto sensor of removing contamination.When not having dirt, the speed of water flow is basically identical, and symmetrical blade assembly is by the impulsive force equal and opposite in direction of current, and direction is contrary, cancels out each other, and the magnetic element 4 of sensor of removing contamination would not action, and tongue tube, because not having magnetic field close, would not close.When there being dirt, because water velocity is subject to the stop of dirt, flow velocity is slack-off, the blade assembly at this place reduces by the impulse force of current, and the corresponding other end does not have dirt or dirt to be less than herein, and water flow velocity is greater than herein, the impulsive force that blade is subject to is larger, when two vane stress are uneven, the sliding shoe of the sensor that will make to remove contamination offsets thereupon, drives magnetic element or left or right to move.When magnetic element 4 is near tongue tube, tongue tube closes by magneticaction, just has the signal of Closing Switch to pass to the time relay of power controling box by wire, controls the working time of trash, thus reaches the object of automatic pollutant removal.
The utility model can be used for power station, rainfall pumping station, sewage treatment plant etc., swinging or grab type, have in the trash work of trash rack, the duty of effective control trash, high efficiency work: have dirt to be automatic operation, clean out stopping automatically standby, energy-conserving and environment-protective, decrease wear and tear in machines, extend the serviceable life of equipment.
Particularly on river course, in the bucket grab raking equipment work of many row's trash racks, flood peak period efficiency is very low, there is the trash rack that the needs of dirt are cleared up, because the arrangement of position is rearward, to wait on the contrary, come position forward be but the sky of grabbing, waste time power consumption without benefit, after mixing this sensor of removing contamination, when there being dirt, grab bucket is directly grabbed to this position and is dragged for, high efficiency and time conservation, fast energy-saving.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
