[0002] Currently, water quality monitoring personnel often use a bucket and a rope to collect water samples. The rope is attached to the bucket. The bucket is then placed underwater at the desired depth using the rope. However, this method is overly simple. When sampling at a distance from the shore, it often requires the use of a bridge or boat, which increases labor and material resources, as well as time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by the utility model is to provide a water quality sampling device and method, which can conveniently place the sampling bucket to a target position far away from the shore for sampling, and at the same time greatly reduce the labor intensity of the operator.

[0004] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a water quality sampling device, comprising a sampling bucket and a pull rope tied to the sampling bucket, and further comprising:

[0005] A support rod, the length of which is adjustable;

[0006] A guide ring is provided at the head end of the support rod, and the pull rope can slide through the guide ring;

[0007] The float is arranged at the head end of the support rod, and when the float is placed in water, it can support the weight of the support rod.

[0008] Furthermore, the support rod includes a plurality of sleeve rods which are assembled in sequence, the float is arranged on the sleeve rod at the tail end, and the guide ring is installed on the sleeve rod at the head end.

[0009] Furthermore, the support rod also includes a rope, one end of which is fixed to the sleeve rod at the head end, and the other end of which can be sleeved and fixed on the sleeve rod at the head end.

[0010] Furthermore, the support rod also includes a hanging buckle, and a hanging buckle is provided on the outer wall of the head end of each sleeve rod, and the pull rope can slide through all the hanging buckles in sequence.

[0011] Furthermore, it also includes a wire take-up device, which is arranged on the sleeve rod at the tail end and is used to reel in the pull rope.

[0022] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0023] See Figures 1 to 2 The utility model provides a water quality sampling device, including a sampling bucket 100, a pull rope 200, a support rod 300, a guide ring 400 and a float 500.

[0024] Specifically, the pull rope 200 is attached to the sampling barrel 100. The length of the support rod 300 is adjustable. A guide ring 400 is provided at the head end of the support rod 300, through which the pull rope 200 can slide. A float 500 is provided at the head end of the support rod 300. When the float 500 is placed in water, the float 500 can support the weight of the support rod 300.

[0025] When in use, the head end of the support rod 300 is placed in the water. Under the action of the float 500, the head end of the support rod 300 is always located on the water surface. Then the support rod 300 is slowly extended to the required length, and the head end of the support rod 300 is located directly above the destination where sampling is required. During the movement of the support rod 300, the support rod 300 drives the sampling bucket 100 to move. After reaching above the destination, the pull rope 200 is lengthened and the sampling bucket 100 descends. When it descends to the target depth, the rope is stopped and sampling is performed at the target depth. After sampling is completed, the pull rope 200 is retracted, and the support rod 300 is retracted at the same time. The float 500 and the sampling bucket 100 are driven back to the shore by the support rod 300.

[0026] By using the above-mentioned sampling device, the sampling bucket 100 can be conveniently placed at the target position. At the same time, since the float 500 can provide support force to the support rod 300, the labor intensity of the operator can be greatly reduced. At the same time, with the auxiliary support of the support rod 300, the probability of the pull rope 200 drifting with the water can be greatly reduced, thereby improving the sampling accuracy.

[0027] In this embodiment, the support rod 300 includes a plurality of sleeve rods 310 that are sequentially assembled. The float 500 is arranged on the first section of the sleeve rod 310, and the guide ring 400 is installed on the first end of the sleeve rod 310. When in use, the support rod 300 can be extended by simply pushing the sleeve rods 310 out in sequence.

[0028] As a preferred embodiment, the support rod 300 further includes a rope 320, one end of which is fixed to the sleeve rod 310 at the tail end, and the other end of which can be sleeved and fixed to the sleeve rod 310 at the head end, thereby preventing the support rod 300 from extending arbitrarily.

[0029] As another preferred embodiment, the support rod 300 further includes a buckle 330 , and a buckle 330 is provided on the outer wall of the head end of each sleeve rod 310 , and the pull rope 200 can slide through all the buckles 330 in sequence.

[0030] The hanging buckle 330 can limit the pull rope 200 and prevent the pull rope 200 from moving around or getting entangled with other objects, thereby affecting the sampling operation.

[0031] In another preferred embodiment, the device further includes a wire reel 600 , which is disposed on the sleeve rod 310 at the tail end and is used to reel in the drawstring 200 .

[0032] Specifically, the cable take-up device 600 includes a central shaft 610, a reel 620, a handle 630, and a locking member 640. The central shaft 610 is fixed to the sleeve rod 310 via a bracket. The reel 620 is rotatably mounted on the central shaft 610. The handle 630 is mounted on the reel 620, and the locking member 640 is mounted on the reel 620 and can be locked to the bracket.

[0033] When the pull rope 200 needs to be wound, the locking member 640 is first loosened, and then the reel 620 is rotated by the handle 630 to wind the line. After the line is wound, the locking member 640 is locked. When the line needs to be released, the locking member 640 is first loosened and the pull rope 200 is pulled outward.

[0034] In a specific embodiment, the locking member 640 is a locking screw that is threadedly connected to the winding wheel 620. By rotating the locking screw, the end of the locking screw can abut against the central shaft 610. When the winding wheel 620 needs to be locked, the locking screw is rotated until its end abuts the central shaft 610. Conversely, the locking screw is rotated in the opposite direction to disengage the locking screw from the central shaft 610.

[0035] Specific usage of the above water quality sampling device:

[0036] When in use, place the head end of the support rod 300 in water, then loosen the locking screw, and slowly pull out each section of the sleeve rod 310, and extend the support rod 300 so that the head end of the support rod 300 is directly above the destination where sampling is required. After reaching above the destination, fix the support rod 300, and then continue to lengthen the pull rope 200, and the sampling bucket 100 descends. When it descends to the target depth, stop releasing the rope, and take samples at the target depth. After sampling is completed, retract the pull rope 200 and the support rod 300 at the same time, and drive the float 500 and the sampling bucket 100 to be retracted to the shore through the support rod 300.

[0037] By using the above-mentioned sampling device, the sampling bucket 100 can be conveniently placed at the target position. At the same time, the float 500 can provide support force to the support rod 300, which can greatly reduce the labor intensity of the operator. At the same time, with the auxiliary support of the support rod 300, the probability of the pull rope 200 drifting with the water can be greatly reduced, thereby improving the sampling accuracy.
