Abstract
The utility model relates to a channel flow velocity sensor suitable for flow velocity measurement and flow metering of a channel in an irrigated area. The technical scheme of the utility model is that the channel flow velocity sensor comprises an impeller (1), a magnet disc (2), a magnetic sensing device (3) and a shell (4). An impeller shaft (5) is arranged on the shell. The magnet disc is arranged on the impeller. The magnetic sensing device is arranged beside the magnet disc. The magnet disc is provided with a plurality of magnets matched with the magnetic sensing device. The utility model has the advantages that (1) local equipment is integrated in advance, and thus, both installation and maintenance in the use field are very convenient; (2) the whole channel flow velocity sensor can be immerged in water for a long time; (3) the channel flow velocity sensor can effectively avoid winding of floatage; and (4) the channel flow velocity sensor has convenient installation and maintenance and low cost and has no drifting problem.
Description
Affiliated technical field:
The utility model relates to a kind of channel flow speed sensors, is applicable to the fluid-velocity survey and the flow metering of irrigated area channel.
Background technology:
At present, irrigation canal final stage channel particularly in the water conservancy industry since distribute wide, quantity is many, the flow monitoring means fall behind
,The final stage channel that the low discharge gentle slope is fallen does not have suitable automatic monitoring means, exerts heavy pressures on for use department.If there is drifting problem in the employing ultrasonic flow transducer, cost height, installation and maintenance are all inconvenient.
The utility model content:
The utility model purpose provides a kind of channel flow speed sensors, is particularly suitable for that the gentle slope falls, the low discharge channel adopts the flow velocity area-method to measure water, and convenient for installation and maintenance, cost is low, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the channel flow speed sensors comprises impeller, lifting magnet, magnetosensitive device, shell, impeller shaft is arranged on the shell, and lifting magnet is arranged on the impeller, and magnetosensitive device is arranged on by the disk iron, disk iron is provided with some magnet, is complementary with magnetosensitive device.
Each blade plane and impeller shaft be arranged in parallel on the impeller, and the impeller blade is the tazza type.
Lifting magnet is made of non magnetic disk and magnet, is evenly studding with a plurality of independent magnet near the disk border part.Lifting magnet and the coaxial setting of impeller, magnet is fixed together outwardly.
Said shell is semicircle shell, semi-circular shell have semicircle above and below, impeller is arranged in the middle of it, the impeller shaft two ends are taper.Magnetosensitive device is arranged on semi-circular shell inboard, the place that the magnet magnetic property is sensed on the lifting magnet.
The channel flow speed sensors is installed on the channel sidewall, and impeller shaft is provided with perpendicular to ground, and impeller is whole basic to be arranged in parallel with the water surface, and impeller plate is perpendicular to water (flow) direction, and moves with current, can effectively avoid the floating thing winding.
Adopt the utility model, when ditch water flow promotion wheel rotation, impeller drives lifting magnet and rotates, a plurality of magnet on the lifting magnet make magneto sensor send pulse signal one by one near magneto sensor, and current are fast more, wheel speed is also fast more, and pulsed quantity is big more, therefore measures flow velocity.
Magnet, magneto sensor are the technique known contents in the utility model, and for example: magnetosensitive device is tongue tube or Hall element, and the magnet of magnetosensitive device on lifting magnet is through the out-of-date pulse signal that sends.
The magneto sensor lead-in wire adopts water-proof cable, and the each several part of channel flow speed sensors comprises that impeller, lifting magnet, magnetosensitive device, semi-circular shell, axle, axle bed integrate, and can make in batches in factory.
The utlity model has following advantage:
1. because terrain equipment is whole in advance integrated, on-site installation and maintenance are all very convenient using;
2. whole channel flow speed sensors can immerse in the water for a long time and use;
3. can effectively avoid floating thing to twine;
4. convenient for installation and maintenance, cost is low, does not have drifting problem.
