Cup, the problem of failure so as to cause the detection method.
Further, detection method includes the following steps：
S1 carries out S types to test agent or intersects five point sampling being sampled；
S2 mixes the reagent of sampling；
Test is put into the inside of groove by S3 with measuring cup, rotates clockwise the first handwheel, and the first transmission shaft turns clockwise at this time
Dynamic, the plus thread road and left-hand thread road opened up on the first transmission shaft will drive two bung flanges to be moved to one side close to each other
Dynamic, two slide bars are also moved to one side close to each other at this time, to which two slide bars push two telescopic rods to oppress two bullets
Spring is close to each other, and two springs push two clamping plates close to each other to clamp measuring cup, stop when measuring cup cannot be swung left and right
Rotate the first handwheel；
S4 takes filtered reagent 50g to pour into measuring cup, 250ml distilled water is taken to pour into measuring cup, quiet with glass bar stir about minute
It sets half an hour, clarifies；
S5 first rotates counterclockwise third handwheel, is moved right under the threaded function of loop coil to the second screw rod, at this time the second spiral shell
The left end of bar will pull ambulatory splint that it is made to be rotated clockwise around pin by multi-directional ball, to make two non-slip mats separate, this
When PH test paper is put into two non-slip mats between, and rotate clockwise third handwheel, the screw thread to the second screw rod in loop coil is made
It moving downward under, the left end of the second screw rod will push ambulatory splint that it is made to be rotated counterclockwise around pin by multi-directional ball at this time,
To which two non-slip mats are close to each other, to clamp PH test paper, stop operating third handwheel after PH test paper is by firm clamping；
S6 rotates clockwise the second handwheel, and worm screw rotates clockwise at this time, and the worm gear to be meshed with worm screw drives thread barrel
It rotates clockwise, the first screw rod moves downward under the threaded function of thread barrel at this time, to drive clamp system and PH test paper
It moves downwardly into measuring cup, when the liquid in the bottom end and measuring cup of PH test paper intersects about cm, the second handwheel is inverted, this
When worm screw rotate counterclockwise, to which the worm gear that is meshed with worm screw drives thread barrel to rotate counterclockwise, the first screw rod is in spiral shell at this time
It is moved upwards under the threaded function of line cylinder, to drive clamp system to be moved upwards with PH test paper, when the bottom end of PH test paper is left
Stop operating the second handwheel after measuring cup；
S7 is compared when PH test paper leaves in the liquid in measuring cup 20~30 seconds with colorimetric card, you can learn the acid of the reagent
Basicity；
S8 is pinched the PH test paper the other hand and shakes third handwheel counterclockwise, the second screw rod is in spiral shell on the other hand when the experimental test finishes
It is moved right under the threaded function of ring, the left end of the second screw rod will pull ambulatory splint to keep it suitable around pin by multi-directional ball at this time
Hour hands rotate, and to make two non-slip mats separate, at this time can take out PH test paper.
Compared with prior art, the environment measuring reagent acid-base value detection device and its detection method have following beneficial
Effect：
1, the present invention can convert the rotation of the first transmission shaft to plus thread road and left-hand thread by the way that the first transmission shaft is arranged
Screw action between road and two bung flanges, so as to make two the first slide bars drive two clamping plates close to each other, to real
The purpose being now clamped to measuring cup effectively prevents measuring cup from toppling over the skin that the liquid for causing it internal spills and damage personnel
Skin, can be by the rotation for being converted into thread barrel of worm screw, to first under the engagement of worm screw by the way that worm gear is arranged
Screw rod carries clamp system and can move up and down under the threaded function of thread barrel, and the progress of PH test paper need to be held by solving existing peasant
The problem of reagent detects effectively avoids the liquid in measuring cup and is stained with tester's skin and cause asking for tester's skin injury
Topic, and testing result is more accurate, avoids the entrance of impurity.
2, the present invention can convert the second screw rod to swinging for ambulatory splint by the way that the second screw rod is arranged,
To realize the clamping to PH test paper, by the way that straight slot is arranged, spring can be made to stretch in sleeve, to effectively avoid user
Overexert when operating clamping device and be caught broken measuring cup, by the way that rubber pad is arranged, effectively avoid clamping plate directly with measuring cup phase
Contact causes measuring cup to damage, and by setting limiting plate, effectively avoids slip ring and skids off third slide bar, the device is caused to damage,
Be located at the surface of measuring cup by the way that the first screw rod is arranged, effectively avoid because the first screw rod tilt cause PH test paper cannot smoothly into
The problem of entering measuring cup, failing so as to cause the detection method.
