Description
Technical field
The utility model belongs to the Measurement of Canal Water Stage technical field, particularly relates to a kind of channel from the simple and easy water level logging system of note formula.
Background technology
Measurement of Canal Water Stage field in prior art, present main level measuring modes such as ultrasonic water level sensor, open channel water gauge method that adopt, simple to operate because of it, be convenient to the advantage widespread use such as management.
Ultrasonic water level sensor formula fluviometer utilizes the ultrasonic reflections principle to measure vertical range between the water surface and sensor, when ultrasonic sensor is installed at the bottom of the canal as reference field, can record the channel actual water level.
The water gauge method adopts the mode that rule vertically is fixed in rectangle canal wall, records the scale position of the water surface with automatic shooting system, and then measures water level.
The problem that prior art exists is: supercritical ultrasonics technology and water gauge method are all measured the actual range of the channel water surface at the bottom of the canal.The time turbulent flow water surface will produce certain fluctuation by certain flow when channel, and be subject to the impact of nature wind speed size, with making error between measured water level and real water level surpass the permissible value of standard, cause the flow measurement precision to be difficult to satisfy the requirement that Irrigation Water is managed.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of channel from the simple and easy water level logging system of note formula, solve the problem of the surface measurement error that is caused by the water level fluctuation that is caused by turbulent fluidised form and natural wind speed of prior art existence.
Channel is characterized in that from the simple and easy water level logging system of note formula: comprise well logging, hydrostatic cylinder, pressure transducer, communicating pipe, secondary instrument, iron stand, wire, channel, well lid, the well head place of described well logging is screwed iron stand is installed; Described hydrostatic cylinder bottom is equipped with pressure transducer, and the bottom of hydrostatic cylinder was communicated with channel by communicating pipe; Described secondary instrument is connected with pressure transducer by wire; Described iron stand is installed with secondary instrument; The bottom of the bottom of described channel and hydrostatic cylinder is positioned at same benchmark elevation; Described well lid is covered in the well head place of well logging.
Described well logging is positioned at well logging cheats, and the deep equality of well logging hole and channel.
The inboard of described channel is equipped with through hole towards the direction of well logging, is positioned at this through hole communicating pipe.
Can bring following beneficial effect by above-mentioned design proposal the utility model: measuring accuracy is high, the still water level that forms in the hydrostatic cylinder that pressure transducer is surveyed is close to ripple disable, avoided the water level fluctuation that is caused by turbulent fluidised form and natural wind speed and the error in measurement that causes guaranteed the precision of water-level observation under different situations.
Construction technology is simple, only needs to dig a well logging at Qu Dishang during construction and cheats, and the well logging that has installed is put in the hole of logging well, and communicating pipe is connected with the hydrostatic cylinder work of getting final product, and is applicable to the measurement of different channel conditions.
With low cost, can be mass and be applied to whole canal system level measuring.Institute's measurement information can dock with control system, is applied in channel robotization control and management.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is that the utility model channel is from the vertical view of the simple and easy water level logging system of note formula.
Fig. 2 is that the utility model channel is from the A-A cut-open view of the simple and easy water level logging system of note formula.
1-well logging, 2-hydrostatic cylinder, 3-pressure transducer, 4-communicating pipe, 5-secondary instrument, 6-iron stand, 7-wire, 8-channel, 9-well lid, 10-trash rack, 11-canal dike in figure.
Embodiment
As shown in Figures 1 and 2, a kind of simple and easy water level logging system of the formula of note certainly for measuring the channel water level comprises well logging, hydrostatic cylinder, pressure transducer, communicating pipe, secondary instrument, iron stand, wire, channel, well lid.Pressure transducer 3 is equipped with in hydrostatic cylinder 2 bottoms, and hydrostatic cylinder 2 bottoms are formed with channel 8 by communicating pipe 4 and are communicated with.Wherein, hydrostatic cylinder 2 bottoms and channel 8 bottoms are positioned on same benchmark elevation.Iron stand 6 is screwed in the well logging mouth and locates, and secondary instrument 5 is fixed on iron stand 6, and secondary instrument 5 is connected with pressure transducer 3 by wire 7, and well lid 9 is placed on the well head place of well logging 1.
Installation: according to well logging 1 size canal dike 11 dig one with hole such as the dark well logging of channel 8 grades, side direction well logging direction punching in the channel, the communicating pipe 4 of an end being equipped with trash rack 10 is put into boring.The well logging 1 that has made is put in well logging hole, the hydrostatic cylinder 2 that pressure transducer 3 is housed was connected with communicating pipe and is fixed in 1 bottom of logging well (requiring hydrostatic cylinder 2 bottoms and channel 8 bottoms to be in same benchmark elevation).With screw, iron stand 6 is fixed in the well head place of well logging 1, then secondary instrument 5 is fixed on iron stand 6, with wire 7 connecting secondary instrument 5 and pressure transducer 3.
When using that this uses is novel carries out Measurement of Canal Water Stage, after guaranteeing that each apparatus installation correctly, after carrying out water-proofing treatment with marine glue, can carry out the measurement of water level work.
