Referring to Figure 10, be provided with ground wire stube cable 27 between reel truck 3 and the browpiece 8.Because cable 11 proportional relations in water level depth and the well head pulley, the number of pulses of photoelectric coded disk 87 is directly proportional with the degree of depth.In probe contact water surface moment, probe forms the loop with probing shell, sends signal, and MCU receives and also writes down water surface detection signal and water level depth signal, carries out the demonstration and the warning of water level depth.Alarm 24 is a voice guard, is installed in instrument internal.As this machine side plate of read out instrument as shown in Figure 9.
The following describes the installation and the course of work of the utility model underground water table detection instrument.Referring to Figure 10:
1. well head pulley base is inserted in the surface well muzzle pipe, winch is fixed on well head pulley 2 Mi Chu ground.Probe is walked around the well head pulley and vertically is tied in the well by inserting tube.
2. with detection instrument depth registration and corresponding one by one the inserting of well head pulley depth registration jack, winch water level mark and corresponding one by one the inserting of detection instrument water level mark socket.
3. cable has 2 meters marks apart from 2 meters of probe, transfers when probe, and with 2 meters markers align well head zero points, 2 meters is initial depths.That is to say that probe transferred 2 meters, the degree of depth is since 2 meters countings.
4. opening power, hand winch speed is evenly descended payout, at this moment, instrument is along with cable is transferred, the automatic record of the degree of depth, when probe touches the water surface, instrument sends " pout--toot--pouts " alarm sound, and LED light 26 is bright simultaneously, and the expression probe has entered in the water, instrument latchs water level depth numerical value this moment, can read the water level latched value.
Specify the method for manipulating of the utility model underground water table detection instrument below.
1. " 0 " point is provided with:
Referring to Fig. 9, the degree of depth drives photoelectric coded disk by the well head pulley and realizes record, and in the following payout process, speed is wanted evenly, and cable will contact with pulley and coincide, and does not skid.For cable is steadily transferred,, that is to say that depth registration " 0 " point is 2 meters having made a mark apart from 2 meters of probe.Claiming 2 meters is initial depth, and initial depth can be provided with arbitrarily." setting/measurement " switch is got to " setting ", show by " parameter " key
Figure Y20082012461200061
Expression " 0 " mark is 2 meters, that is to say the degree of depth from 2 meters opening entries, if from 3 meters opening entries, so just this number is made as 3 meters, and the degree of depth is from 3 meters opening entries.
2. initial depth and depth coefficient setting:
The first step: " setting/measurement " switch is got to " setting " position, and by " parameter " key, the charactron that be provided with flicker is whenever pressed once " parameter " key charactron and is moved to right one, adjusts digital by " rise, downward modulation " key.Be set at 2 meters, then show such as initial depth
Figure Y20082012461200062
Second step: continue to show by " parameter " key
Figure Y20082012461200063
Being set to 4000,4000 when dispatching from the factory is depth coefficient, does not change.
The 3rd step: scaling position is set, shows
Figure Y20082012461200064
Rightmost one digit number sign indicating number pipe is 2,2 decimals behind the expression radix point, if be made as 3, and 3 decimals behind the expression radix point.
Generally being designed to the well head pulley coefficient of correspondence value that rotates a circle is 4000.
Figure Y20082012461200071
If service time, pulley remote had wearing and tearing, measuring accuracy surpasses error range, can realize error correction by changing depth coefficient.
3. instrument shows
During this apparatus measures state, window has 4 parameters to show, left window display parameter number, the right window display parameter value.
No. 1 parameter: show that cable transfers the degree of depth, the degree of depth is a plus-minus counting, transfer the Shi Weijia counting, on when carrying for subtracting counting.
No. 2 parameters: show that probe touches the depth value of the water surface, water level value just, the moment depth value of running into the water surface when probe is latched.No matter probe continues to transfer, and the water level value of this moment can not change yet, so that manually make a copy of.
No. 3 parameters: demonstration be " 0 " some record value, if cable has been transferred 2 meters, then 2 meters marks are exactly that " 0 " puts record value, are called initial depth.
No. 4 parameters: the display depth coefficient value, when this instrument dispatched from the factory, what all be provided with was 4000.
When probe was run into the water surface, instrument sent the chimes of doom of " toot-toot-toot ", and at this moment, LED light 26 is bright, and the expression probe enters in the water, shows No. 2 parameters by " parameter " key, and No. 2 parameters promptly are water level values.Remove alarm sound by " rise " key, LED light 26 is extinguished.Note by " resetting " key,, latch water level value and No. 1 parameter depth value will be eliminated if press " resetting ", only when beginning down payout, to behind good " 0 " point just by " resetting " key.LED light 26 is extinguished when popping one's head in out the water surface.
Instrument continuously-running 48 hours, when turning on the power switch, instrument sends lasting alarm sound, and expression instrument electric weight deficiency must be charged, during this machine of use charging inlet 43, the red plug of charger connects panel power supply "+" utmost point, and black plug connects "-" utmost point, and the charger pilot lamp shows red, when pilot lamp became green, expression was full of.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design proposal prerequisite; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
