Technical Field
[0001] This utility model belongs to the field of water quality monitoring technology, specifically relating to a multi-layer deep sampling device for water environment monitoring. Background Technology
[0002] Water quality monitoring is a crucial link in environmental protection and water resource management, playing a vital role in ensuring drinking water safety, preventing water pollution incidents, and maintaining ecological balance. Obtaining accurate and comprehensive water quality information is fundamental to formulating scientific environmental protection policies and assessing the health status of water bodies. Water sampling typically requires collecting samples from different depths to obtain more comprehensive and accurate water quality data.
[0003] However, current sampling devices can usually only sample a single depth at a time, requiring the collected water to be transferred into a collection bottle for collection. When sampling at multiple depths, the sampling operation needs to be repeated, which is a cumbersome process and causes a lot of trouble for users. To address this issue, the applicant proposes a multi-depth sampling device for water environment monitoring. Utility Model Content
[0004] The purpose of this invention is to provide a multi-layer depth sampling device for water environment monitoring, which eliminates the need for repeated sampling operations during multi-layer depth sampling, simplifies the sampling process, and brings greater convenience to users.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sampling mechanism and an operating mechanism mounted on one side of the sampling mechanism;
[0008] The sampling mechanism includes a support base, a limiting frame is slidably installed on the top of the support base, a limiting seat is fixedly installed on the top of the support base at the rear end of the limiting frame, a sampling syringe is clamped and fixed between the limiting seat and the limiting frame, a push rod corresponding to the tail end of the sampling syringe is slidably installed inside the support base, and a locking frame that engages with the push rod is hinged to the bottom of the support base.
[0009] The operating mechanism includes a sleeve hinged to one side of the support base and a movable block slidably installed at the bottom of the support base. The movable block corresponds to the locking frame, and a telescopic rod is sleeved on the top of the sleeve.
[0010] Preferably, a filter cover corresponding to the head end of the sampling syringe is fixedly installed at the front end of the limiting frame, and a second thrust spring is connected between the push rod and the support base.

[0012] Preferably, a tension spring is connected between the slider and the movable groove, and a handle is fixedly installed on one side of the telescopic rod.
[0013] Preferably, the bottom of the push rod has a slot for the engaging frame to engage, and a first thrust spring is connected between the engaging frame and the support base.
[0014] Preferably, a winding wheel is rotatably mounted on the top of the telescopic rod, a rope is connected between the winding wheel and the moving block, and a pulley corresponding to the rope is rotatably mounted on the front end of the sleeve rod.
[0015] Preferably, the rear end surfaces of the telescopic rod and the sleeve rod are engraved with scale lines, and the telescopic rod and the sleeve rod are fixed together by a fixing knob.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] (1) This utility model is equipped with a sampling mechanism, which can install the sampling syringe between the limiting frame and the limiting seat. By placing the sampling mechanism into the water body and moving it by pulling the moving block, the locking frame and the push rod can be separated, and the push rod can push the piston rod of the sampling syringe to move, so that the water body can be easily sucked into the sampling syringe.

[0029] Example 1:
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a multi-layer depth sampling device for water environment monitoring includes:
[0031] Sampling mechanism 2 and operating mechanism 1 assembled on one side of sampling mechanism 2;
[0032] The sampling mechanism 2 includes a support base 21, a limiting frame 26 is slidably installed on the top of the support base 21, a limiting seat 28 is fixedly installed on the top of the support base 21 at the rear end of the limiting frame 26, a sampling syringe 3 is clamped and fixed between the limiting seat 28 and the limiting frame 26, a push rod 24 corresponding to the tail end of the sampling syringe 3 is slidably installed inside the support base 21, and a locking frame 22 that engages with the push rod 24 is hinged to the bottom of the support base 21.
[0033] The operating mechanism 1 includes a sleeve rod 11 hinged to one side of the support base 21 and a movable block 18 slidably installed at the bottom of the support base 21. The movable block 18 corresponds to the locking frame 22. A telescopic rod 12 is sleeved on the top of the sleeve rod 11.
[0034] As can be seen from the above, by flipping the support base 21 to a horizontal state during use, inserting the water inlet end of the sampling syringe 3 into the limiting frame 26, and pushing the limiting frame 26 forward, the tail end of the sampling syringe 3 can be engaged with the limiting seat 28, allowing the piston rod of the sampling syringe 3 to extend out of the limiting seat 28, and at the same time, the push rod 24 can extend to the bottom position of the piston rod of the sampling syringe 3. By applying a squeezing action to the sampling syringe 3 through the limiting frame 26, the sampling syringe 3 can be easily clamped and fixed, and the installation operation is convenient and quick.
[0035] The telescopic rod 12 slides up and down within the sleeve rod 11, allowing for easy height adjustment according to the sampling depth. By holding the telescopic rod 12, the sampling mechanism 2 can be placed into the water. When the desired depth is reached, the moving block 18 slides to the right along the bottom of the support base 21, allowing the moving block 18 to pass through multiple locking frames 22 in sequence. When the moving block 18 passes through the locking frame 22, it can squeeze one end of the locking frame 22, causing the locking frame 22 to flip, thus releasing the locking frame 22 from the push rod 2. The locking of 4 allows the push rod 24 to pop out. The movement of the push rod 24 can push the piston rod of the sampling syringe 3 to move, which can automatically draw water into the sampling syringe 3. By arranging and installing multiple sampling syringes 3, it is convenient to sample water at different depths without the need for tedious repeated sampling operations, which simplifies the sampling process. There is no need to import it into the bottle for collection. The water sample can be directly imported into the detection equipment for detection operation by disassembling the sampling syringe 3, which brings more convenience to the user.
[0036] After use, the support base 21 can be folded to one side of the sleeve rod 11, which can fold and store the sampling mechanism 2, making it easier to reduce the size of the device and facilitate storage operations, so that staff can easily carry and transport it, thus improving convenience.
[0037] Depend on Figure 5 It can be seen that the front end of the limiting frame 26 is fixedly installed with a filter cover 27 corresponding to the head end of the sampling syringe 3, and a second thrust spring 25 is connected between the push rod 24 and the support base 21.
[0038] As can be seen from the above, the filter cover 27 can intercept large particles of impurities in the water, avoiding clogging of the sampling syringe 3. The second thrust spring 25 can apply a thrust to the push rod 24, which can cause the push rod 24 to pop out, enabling the push rod 24 to push the piston rod of the sampling syringe 3, making it easier to draw water into the sampling syringe 3.
[0039] For details, please refer to Figure 5 As shown, the limiting frame 26 and the support base 21 are slidably installed together by a slider 29, and the top of the support base 21 is provided with an active groove 210 for the slider 29 to slide.
[0040] As can be seen from the above, the slider 29 can slide along the movable groove 210, which can move the limit frame 26, increase the distance between the limit frame 26 and the limit seat 28, and allow the sampling syringe 3 to be installed between the limit frame 26 and the limit seat 28.
[0041] For details, please refer to Figure 4 and Figure 5As shown, a tension spring 211 is connected between the slider 29 and the movable groove 210, and a handle 15 is fixedly installed on one side of the telescopic rod 12.
[0042] As can be seen from the above, the tension spring 211 can apply a pulling force to the slider 29, which can make the limiting frame 26 compress the sampling syringe 3, making it easy to clamp and fix the sampling syringe 3. The operating mechanism 1 can be easily held by the grip handle 15, and the sampling mechanism 2 can be put into the water for sampling.
[0043] Example 2:
[0044] refer to Figure 5 As shown, the bottom of the push rod 24 is provided with a slot 212 for the locking frame 22 to engage, and a first thrust spring 23 is connected between the locking frame 22 and the support base 21.
[0045] As can be seen from the above, the first thrust spring 23 can apply a thrust to one end of the locking frame 22, so that the other end of the locking frame 22 can be locked into the slot 212, which can lock the push rod 24 and prevent the push rod 24 from popping out when not sampling.
[0046] refer to Figure 4 As shown, a winding wheel 16 is rotatably mounted on the top of the telescopic rod 12, and a rope 17 is connected between the winding wheel 16 and the moving block 18. A pulley 19 corresponding to the rope 17 is rotatably mounted on the front end of the sleeve rod 11.
[0047] As can be seen from the above, by operating the winding wheel 16 to rotate, the rope 17 can be wound up. The pulley 19 provides rolling support for the rope 17, which allows the rope 17 to pull the moving block 18 from left to right, making it convenient to squeeze multiple clamping frames 22 in sequence. According to different water depths, multiple sampling syringes 3 can be triggered to perform water suction operations in sequence.
[0048] refer to Figure 2 As shown, the rear end surfaces of the telescopic rod 12 and the sleeve rod 11 are engraved with scale lines 13, and the telescopic rod 12 and the sleeve rod 11 are fixed together by a fixing knob 14.
[0049] As can be seen from the above, the scale line 13 allows staff to easily and intuitively observe the depth of the sampling mechanism 2 below the water surface, facilitating multi-level depth sampling operations. The fixed knob 14 can fix the telescopic rod 12 at a specified height, facilitating the extension of the working height and preventing the telescopic rod 12 from accidentally sliding.
