Abstract
The utility model discloses a water level monitoring device, including having the records of distance by the log round, connect rope, float and balance weight, float and balance weight hang respectively through connecting the rope the both sides of having the records of distance by the log and taking turns, have the records of distance by the log the wheel through torsion spring and the encoder pivot coaxial coupling of setting on the well logging support. The utility model discloses a float -type water level measurement device has simple structure, reasonable, and advantages such as reliability height, strong adaptability can be used for liquid level measurement for a long time, simultaneously since have the records of distance by the log the wheel through torsion spring with set up the encoder pivot coaxial coupling on the well logging support, when round taking place to deflect when having the records of distance by the log, torsion spring's turning power drives round home of having the records of distance by the log, avoid having the records of distance by the log the wheel wherein the weight of one side, have the records of distance by the log to take turns and to turn round when the water level changes once again far above the weight of opposite side.
Description
Technical field
The utility model relates to a kind of Level monitor.
Background technology
Water level measuring and controlling device is the important measuring and controlling equipment of hydroelectric power plant, the water levels of upstream and downstream of hydroelectric power plant is the significant data of Safety of Flood Control, trash rack pressure reduction affects unit output, waterwork safety, head value affects speed regulator combination curve, and then affect unit efficiency even safe and stable operation, therefore water level measuring and controlling device need meet long time stability operation.Current hydroelectric power plant's water level measuring and controlling device generally adopts Gray's code value of customization instrument to collect front end level sensor, and in operation maintenance, there is following problem: lightning protection, poor anti jamming capability, instrument, sensor are fragile.
For this problem, also have some to adopt float gauge to carry out the device of level measuring in water conservancy industry, reason is that float gauge measuring accuracy does not limit by range, and durable in use.But, traditional float gauge cannot eliminate the measuring error that the weight because of wheel both sides wire rope itself of having the records of distance by the log causes, this is because when SEA LEVEL VARIATION, float can be driven to rise or decline, have the records of distance by the log wheel two ends wire rope weight also change, thus the displacement of the wheel actual rotation that causes having the records of distance by the log and actual water level changing value are not etc., range of stage is larger, so require that the length of wire rope is longer, water-level gauge because of the absolute error of wire rope in full range larger, and the weight of weight far above opposite side of wherein side is taken turns once have the records of distance by the log, even can cause having the records of distance by the log wheel can not rotation measuring water level.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides a kind of float type water level monitoring device, safely, measures water level accurately.
Technical scheme: Level monitor described in the utility model, comprise have the records of distance by the log wheel, connection cord, float and balance weight, to have the records of distance by the log described in described float and balance weight are suspended on respectively by connection cord the both sides of wheel, described in have the records of distance by the log wheel by torsionspring be arranged on the scrambler rotating shaft of logging well on support and be coaxially connected.
The course of work of the present utility model is, this Level monitor is arranged on above well logging mouth, and when liquid level change, float rises thereupon or declines, and connection cord drive wheel of having the records of distance by the log rotates, and takes turns the coaxial scrambler be connected and reads liquid level delta data with having the records of distance by the log.
The utility model further preferably technical scheme is, described in have the records of distance by the log wheel outer ring on have annular grooving, described connection cord is positioned at described annular grooving.
Preferably, the bottom of described annular grooving is also provided with row's hangnail.
Preferably, described scrambler is absolute value encoder.
Preferably, described connection cord is that wire rope, flat steel band are wherein a kind of.
Beneficial effect: (1) the utility model adopts float type water level measurement mechanism to have simple and reasonable for structure, and the advantages such as reliability is high, strong adaptability, can for a long time for level gauging; Simultaneously due to have the records of distance by the log wheel by torsionspring be arranged on the scrambler rotating shaft of logging well on support and be coaxially connected, when wheel of having the records of distance by the log deflects, the turning power of torsionspring drives wheel homing of having the records of distance by the log, to avoid having the records of distance by the log the weight of taking turns the wherein side weight far above opposite side, when water level changes once again, wheel of having the records of distance by the log can not turn round;
(2) the utility model has annular grooving on the outer ring of wheel of having the records of distance by the log, and the bottom of annular grooving is also provided with row's hangnail, drives and has the records of distance by the log in wheel rotation process, avoid occurring skidding, affect monitoring result at connection cord;
(3) in the utility model, scrambler adopts absolute value encoder, coding is determined by mechanical location, each coding does not uniquely repeat, not by the impact had a power failure, disturb, without the need to memory, without the need to looking for reference point, and need not count always, reading is instant, increases substantially the noiseproof feature of monitoring and the reliability of data.
Accompanying drawing explanation
Fig. 1 is the structural representation of Level monitor described in the utility model.
Embodiment
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
embodiment:a kind of Level monitor, comprises wheel 1 of having the records of distance by the log, connection cord 2, float 3 and balance weight 4, as shown in Figure 1:
Have the records of distance by the log wheel 1 outer ring on have annular grooving, the bottom of annular grooving is also provided with row's hangnail, float 3 and balance weight 4 are suspended on the both sides of wheel 1 of having the records of distance by the log respectively by connection cord 2, and connection cord 2 is that wire rope, flat steel band are wherein a kind of, and connection cord 2 is positioned at annular grooving; Wheel 1 of having the records of distance by the log coaxially is connected with the rotating shaft being arranged on the absolute value encoder 5 of logging well on support by torsionspring.
This Level monitor is arranged on above well logging mouth, and when liquid level changes, float 3 rises thereupon or declines, and connection cord 2 drives wheel 1 of having the records of distance by the log to rotate, and reads liquid level delta data with the coaxial absolute value encoder 5 be connected of wheel 1 of having the records of distance by the log.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
