Abstract
The utility model relates to a water level measuring device of an open channel dam trough. The water level measuring device comprises a magnetostriction displacement sensor, wherein the magnetostriction displacement sensor is composed of an electronic cabin, a measuring rod and a floating ball which are linked together. The water level measuring device is characterized by further comprising a barrel-shaped upper shell and a barrel-shaped lower shell which are sleeved outside the magnetostriction displacement sensor, wherein a barrel-shaped protecting shade is fixedly connected between the upper shell and the lower shell; a through hole is arranged at the bottom of the protecting shade and is fixedly sleeved at the part at which the electronic cabin is combined with the measuring rod; the electronic cabin is arranged inside the upper shell; the measuring rod and the floating ball are arranged inside the lower shell; and a water inlet hole is arranged at the bottom of the side wall of the lower shell. The water level measuring device has the beneficial effects that as the upper shell and the lower shell are fixedly sleeved outside the magnetostriction displacement sensor, and the protecting shade is arranged between the upper shell and the lower shell, the problem of measurement error due to the fact that the water enters the electronic cabin is overcome.
Description
Technical field
The utility model relates to a kind of condensate tank of dehumidifier, particularly a kind of open channel weir notch level measurement device.
Background technology
In water quality monitoring, usually can use sewage open channel meter, be used for measuring the water level or the flow of sewage in the open channel weir notch, to judge the total amount of pollutants discharged of the blowdown enterprise's day or the moon.Traditional sewage open channel meter generally adopts the height of ultrasonic technology measuring weir trough inner water position, calculates corresponding flow through level value and other correlation parameter that records then.Yet adopt the ultrasonic technology measuring liquid level to be subject to the influence of surrounding environment, the level gauging error is bigger, can not accurately measure water level in the open channel weir notch, thereby bring than mistake to flow measurement.
Magnetostrictive displacement sensor has been applied in the hydrographic survey at present, and magnetostrictive displacement sensor is according to the high precision of magnetostriction principle manufacturing, the displacement transducer of long stroke Absolute position measurement.It adopts inner non-contacting metering system, because measuring movable magnet ring does not have directly with sensor self and contacts, is unlikely to be rubbed, wear and tear; Thereby its long service life, adaptive capacity to environment are strong; Reliability is high, and security is good, is convenient to system automation work; Even under abominable industrial environment (oil is burst as receiving easily, dust or other pollution occasion), also can operate as normal.Though magnetostrictive displacement sensor self is wearing and tearing not,, thereby under unwitting situation, cause the error of measurement because the influence of environment possibly cause its electronics storehouse water inlet to make instrument damaged.
The utility model content
The purpose of the utility model provides a kind of open channel weir notch level measurement device that the water inlet of electronics storehouse causes measurement error problem that overcomes.
In order to accomplish above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of open channel weir notch level measurement device; Comprise by electronics storehouse, measuring staff and ball float and connect the magnetostrictive displacement sensor of forming; It is characterized in that: also comprise being sleeved on magnetostrictive displacement sensor outside barrel-shaped upper casing and lower casing, be connected with barrel-shaped protective cover between upper casing and the lower casing, the bottom of protective cover is provided with the junction that through hole and suit are fixed on electronics storehouse and measuring staff; Described electronics position in storehouse is in upper casing, and measuring staff and ball float are positioned at lower casing; The sidewall bottom of described lower casing is provided with the inlet opening.
The lower end of described upper casing and the sidewall upper of protective cover are affixed, and the upper end of lower casing and the side wall lower ends of protective cover are affixed.
The described protective cover outside is provided with handle.
The top center of described upper casing is provided with screw, and the sidewall of upper casing is provided with wire hole.
Described lower casing is set with barrel-shaped outer connecting cylinder outward, and the sidewall of connecting cylinder bottom is provided with water inlet and water delivering orifice outside, and the top side wall of outer connecting cylinder is provided with the buckle that itself and lower casing are fixed.
The beneficial effect of the utility model is: owing at fixing upper casing and the lower casing of the outside suit of magnetostrictive displacement sensor, be fixed with protective cover between upper casing and the lower casing, overcome the water inlet of electronics storehouse and caused the problem of measuring error.
Description of drawings
Fig. 1 is the cut-open view of the utility model.
Among the figure, 1, the electronics storehouse, 2, measuring staff, 3, ball float, 4, upper casing, 5, lower casing, 6, protective cover, 7, wire hole, 8, the inlet opening, 9, outer connecting cylinder, 10, water inlet, 11, water delivering orifice, 12, handle.
Embodiment
The utility model is a kind of open channel weir notch level measurement device, owing at fixing upper casing and the lower casing of the outside suit of magnetostrictive displacement sensor, be fixed with protective cover between upper casing and the lower casing, overcome the water inlet of electronics storehouse and has caused the problem of measuring error.
Below in conjunction with accompanying drawing the utility model is further specified.
When needs carry out level measuring in to the open channel weir notch; The utility model is put into the open channel weir notch, and liquid gets in the lower casing 5 through inlet opening 8, along with lifting ball float 3 beginnings of water level are floated along measuring staff 2; After water level was steady, the instrument in the electronics storehouse 1 was accomplished the measurement to water level.
