[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Referring to Figs. 1 to 4 The embodiment provides a water quality sampler with adjustable sampling depth, which comprises:

[0029] The mounting seat 1 is bent in two places to form two planes, i.e. the upper plane 101 and the lower plane 102. The lower plane 102 is installed on a ship, and the lower plane 102 extends above the water surface of the ship;

[0030] The winding machine 2 is fixedly installed on the lower plane 102. The rope 3 is wound around the winding machine 2, extends from the winding machine 2 to the middle of the upper plane 101, and penetrates the upper plane 101 to extend downward;

[0031] The sampling assembly is fixedly connected to the end of the rope 3 away from the winding machine 2, and the sampling assembly is located below the upper plane 101;

[0032] The measuring assembly comprises several telescopic rods 4 sleeved with each other, the outer surface of the telescopic rods 4 is engraved with length scales, the outermost telescopic rod 4 is fixedly connected with the upper plane 101, and the bottom of the innermost telescopic rod 4 is fixedly connected with the sampling assembly through the connecting rod 5.

[0033] By fixing the mounting seat 1 with the ship, the sampler can move to the water position where sampling is needed, the winding machine 2 winds and unwinds the rope 3, and drives the sampling assembly at the end of the rope 3 to sink or rise, the depth of the sampling assembly sinking is measured by the measuring assembly, the bottom of the measuring assembly follows the sampling assembly to rise or sink, the telescopic rods 4 are telescoped according to the depth of the sampling assembly, and the scale value on the telescopic rod 4 corresponding to the position of the water surface is the depth of the sampling assembly.

[0034] In a further optimization scheme, when the telescopic rods 4 are fully extended, the two adjacent telescopic rods 4 are connected at the tail end, and the length scales on the telescopic rods 4 are continuously marked from bottom to top.

[0035] The telescopic rods 4 are connected at the tail end, the length scales are continuously marked from bottom to top, and thus the scale corresponding to the water surface on the telescopic rod 4 is the sampling depth, and the reading is convenient to observe.

[0036] In a further optimization scheme, when the telescopic rods 4 are fully contracted, a plurality of limit holes 6 are formed in the side surfaces of the telescopic rods 4 corresponding to each other, a limit rod 8 is inserted in the limit hole 6, and the telescopic rods 4 slide from inside to outside in sequence when the telescopic rods 4 are extended.

[0037] When the limit rod 8 is inserted into the bottom of the limit hole 6, all the telescopic rods 4 are limited by the limit rod 8 and are relatively stationary and cannot slide, the limit rod 8 gradually moves outward, the innermost telescopic rod 4 is first released from the limitation and can slide downward and extend, and the top of the innermost telescopic rod 4 is connected with the bottom of the adjacent telescopic rod 4.

[0038] Further optimization scheme, the upper surface 101 is fixed with a rectangular groove 18, the limiting rod 8 is arranged in the rectangular groove 18; the end of the rectangular groove 18 away from the limiting rod 8 is clamped with a plurality of limiting plates 9; the end of the limiting rod 8 extending out of the telescopic rod 4 is fixed with a stop plate 10, the side surface of the limiting rod 8 is sleeved with a spring 11, one end of the spring 11 abuts against the stop plate 10, and the other end is fixed with the outer wall of the outermost telescopic rod 4, the stop plate 10 abuts against the limiting plate 9 under the elastic force of the spring 11; the interval between the plurality of limiting plates 9 matches the thickness of the plurality of telescopic rods 4.

[0039] The spring 11 always keeps a compressed state, so that the stop plate 10 always abuts against the limiting plate 9; when all the limiting plates 9 are inserted in the rectangular groove 18, the limiting rod 8 is inserted at the bottom of the limiting hole 6, and all the telescopic rods 4 cannot slide relative to each other; after one limiting plate 9 is pulled out, the limiting rod 8 moves an end distance out of the limiting hole 6 under the elastic force of the spring 11 until it abuts against the next limiting plate 9; because the distance between the two limiting plates 9 matches the thickness of the telescopic rod 4, the sliding limitation of the inner layer of telescopic rods 4 is removed when one limiting plate 9 is pulled out, so that the distance of the limiting rod 8 pulled out of the limiting hole 6 is controlled, and the number of telescopic rods 4 in contact with the sliding limitation is reasonably controlled.

[0040] Further optimization scheme, the mounting seat 1 is fixed with a plurality of fixed pulleys 12, and the rope 3 slides along the fixed pulleys 12 until it is fixed with the sampling assembly.

[0041] The rope 3 is guided at the bending position and the like by the fixed pulley 12, reduces the friction between the rope 3 and the mounting plate, makes the rope 3 slide more smoothly, reduces the wear and tear, and reduces the position deviation of the rope 3 sliding.

[0043] The water inlet cavity 13 is connected with a plurality of sampling bottles 15, after reaching the corresponding sampling depth, the electromagnetic valve 14 corresponding to one of the sampling bottles 15 can be opened, so that the water in the water inlet cavity 13 flows into the sampling bottle 15, and then the electromagnetic valve 14 is closed, the water quality sample at this depth is obtained, and the depth can be further adjusted to reach another sampling position, the electromagnetic valve 14 corresponding to another sampling bottle 15 is opened, and sampling is performed at this depth. The water samples at different depths can be obtained at one time, the steps of sampling at different depths are reduced, and the sampling efficiency is greatly improved.

[0044] The sampling bottle 15 and the connecting pipe 19 can be connected by thread sealing.

[0045] Further optimization scheme, the top surface and the side surface of the water inlet cavity 13 are communicated with the outside through the screen 16.

[0046] The screen 16 is used to isolate the impurities in water, so as to avoid the impurities in water from entering the water inlet cavity 13 and causing the connecting pipe 19 or the electromagnetic valve 14 to be blocked.

[0047] Further optimization scheme, the lower surface 102 four corners are provided with bolt holes 17.

[0048] The lower surface 102 can be fixed on the deck of a ship or other parts of the ship body through bolts or screws, and installation is convenient and fast.
