The working principle and the using process of the invention are as follows:
when the purpose of improving the reliability is needed to be achieved, firstly, the first pulling block 10 and the second pulling block 13 are matched to enable the two to move relatively, so that the connecting rod 21 drives the water storage pipe 2 to slide in the movable loop bar 1, when the water storage pipe 2 moves, the compression block 5 can drive the sliding block 4 to move, due to the effect of the sliding groove 3, the compression block 5 can drive the water storage pipe 2 to rotate through the matching with the sliding block 4, the rotation of the water storage pipe 2 can drive the spiral blade 11 to rotate, the purpose of stirring the sampling water is achieved, the water stratification caused by water deposition is avoided, and the situation that a water sample to be taken does not have credibility is avoided.
When needs realize convenient to use's purpose, draw the cooperation of piece 13 and press the briquetting 17 through the second, can realize relative movement stock 14 and 2 purposes of standpipe, and then can release rubber buffer 16 by the bottom of standpipe 2 through the removal of stock 14, from the purpose of realizing the inside air of 2 inside air of thoroughly discharge standpipe under the cooperation of connecting plate 15 and exhaust duct 22, and then reach the function that makes things convenient for the staff to carry out the extraction to arbitrary layering water, thereby can realize making things convenient for the staff to use the purpose that this equipment carried out the sample to waste water.
When in use, generally, because the water storage pipe 2 needs to rotate and needs to relatively move relative to the position of the movable sleeve rod 1, if the water storage pipe is not used for a long time, the rotation and pulling of the water storage pipe are relatively laborious, and because the sliding groove is preferably set to be a spiral structure, the resistance of the sliding block 4 is also large when the sliding block rotates, if the lubricating effect is not good, not only the movement and the rotation are difficult, but also the abrasion is greatly improved, so that the service life of the device is seriously reduced, therefore, the specific technical scheme and the field are further improved, a through hole 24 is arranged at the non-overlapping position of the compression block 5 and the connecting hole 7, a plurality of lubricating grooves 23 are arranged on the upper surface of the compression block 5 through the through hole 24, when the compression block 5 moves downwards to be close to the bottom of the accommodating space between the sliding sleeve rod 1 and the water storage pipe 2, the lubricating liquid at the middle lower part or the bottom can enter the lubricating grooves 23 through the through hole, thereby when first spring 8 makes compression block 5 reset, even compression block 5 is located upper portion and has also held lubricating liquid to for next use provides lubrication, lubrication groove 23 is including perpendicular portion 231 and arc portion 232, perpendicular portion 231 is located the upper surface of one side that slider 4 was kept away from to arc portion 232 and with arc portion 232 intercommunication makes lubricating liquid smoothly enter into arc portion 232 through perpendicular portion 231, carries out the storage of lubricating liquid through arc portion 232, as shown in the figure, because the width of arc portion's diameter is big than the width of perpendicular portion, still has the space that holds lubricating liquid in the direction of perpendicular portion to both sides promptly, makes it have good storage effect, perpendicular portion 231 is located through arc portion 232 centre of a circle and the vertical upwards extension line keep away from one side of slider 4, promptly the perpendicular portion is actually located one side that arc portion upside is close to standpipe 2, thereby when great centrifugal force or rocking, the lubricating liquid is shielded by the upper part when moving upwards along the circular arc, the lubricating liquid is prevented from flowing out from the upper side, the storage effect is improved, the communication hole 26 is arranged between the circular arc parts 232, the height of the communication hole 26 is lower as the communication hole is closer to the slide block 4, the storage capacity is improved through the plurality of circular arc parts 232, the depth of the circular arc part is preferably deeper as the communication hole is closer to the slide block 4, so that the lubricating liquid is more favorably conveyed to the slide block 4 from the farthest side, the lubricating liquid is more favorably conveyed to the slide block 4 by arranging the communication hole 26 to be lower as the communication hole is closer to the slide block, the circular arc part 232 close to one side of the slide block 4 comprises a lubricating hole 25 communicated with the side wall of the slide block 4, the diameter of the lubricating hole 25 from the side wall of the slide block 4 to the circular arc part is gradually increased, the lubricating hole 25 is connected with the middle upper part of the circular arc part 232, so that when the lubricating hole is not used, because there is not centrifugal force effect, the lateral wall that lubricated liquid can not be too much shifts to slider 4 from lubrication hole 25, thereby lose the lubricated liquid on the compression piece 5, only when there is centrifugal force effect, the lubricated liquid moves up, thereby can enter into the lateral wall of slider 4 through lubrication hole 25, make its and slider 4 more lubricated, and when preferred spiral chute 3, the downstream that lubricated liquid also can last, thereby lubricate whole spout 3, make to rotate easily and wearing and tearing lower, and when relative movement, the lubricated liquid that is located the bottom also can play better lubricated effect to relative movement. In summary, the invention can drive the lubricating fluid between the sliding sleeve rod and the water storage pipe from the bottom to the upper part through the through hole, and store the lubricating fluid in the lubricating groove after the completion through the arrangement of the compression block, the sliding block and the through hole, the communication hole and the lubricating hole on the sliding sleeve rod and the water storage pipe, when the lubricating fluid is used next time, the lubricating fluid in the arc part enters the lubricating hole through the centrifugal action through the rotation, so as to lubricate the sliding block and the sliding groove, the rotation resistance is small, if the rotation is hard, the lubricating fluid can enter the communication hole before the rotation through the shaking device, so that the rotation is easier, and the upper part at one side of the circle center of the arc part close to the sliding block is closed, namely the vertical part is not located above, at this time, the moving lubricating fluid can be blocked in the arc part even if the rotation is fast, effectively improving the storage effect.
