DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] The following will be combined with Figures 1-4 to give a detailed description of a sampling device for water quality detection in the embodiments of the present utility model.
[0021] Embodiment:
[0022] A sampling device for water quality detection provided by an embodiment of the present utility model, referring to Figures 1 to 4 as shown, includes a sampling cylinder 1 for water quality detection, a scale rope 2, and a conical positioning float 3. A rope buckle 4 is movably connected to the upper part of the sampling cylinder 1. The scale rope 2 is tied to the rope buckle 4. A through hole 5 is opened at the center of the conical positioning float 3. The scale rope 2 passes through the through hole 5. Lock sleeves 6 are fixedly installed at both the upper and lower ends of the conical positioning float 3. The scale rope 2 passes through the lock sleeves 6. A compression bolt 7 is threadedly connected to the outer wall of the lock sleeve 6. In this structure, before taking water, the operator adjusts the position of the conical positioning float 3 on the scale rope 2, so as to adjust the conical positioning float 3 to a position corresponding to the water intake depth. Then, the conical positioning float 3 is fixed on the scale rope 2 through the compression bolt 7 on the lock sleeve 6. Then, the operator can put the sampling cylinder 1 into the water to take a sample. At this time, the columnar positioning float 3 will position the depth of the sampling cylinder 1 into the water, so as to facilitate the positioning of the sampling water level. In this way, sampling will be more convenient, and the position of the conical positioning float 3 can be adjusted according to the sampling water depth, and the adjustment adaptability is good.
[0023] And in actual use, when the scale rope 2 slips out of the hand, the conical positioning float 3 can prevent the sampling cylinder 1 from sinking into the water, and plays a role in positioning, facilitating salvage, and avoiding accidental sinking and loss of the sampling cylinder 1.
[0024] Referring to Figures 1 to 4 as shown, the horizontal plane after the sampling cylinder 1 sinks in place is exactly in the middle of the conical positioning float 3. In this structure, it is convenient for the operator to adjust the position of the conical positioning float 3.
[0025] It should be noted that: The conical positioning float 3 is selected according to the gravity of the sampling cylinder 1 and the buoyancy in water, so as to ensure the buoyancy balance between the conical positioning float 3 and the sampling cylinder 1. Since the water quality sealing gap is not large, and the depth error caused by the water quality density when sinking into the water is within the allowable range relative to the specific sampling error, the buoyancy influence caused by the density difference of the water quality liquid can be ignored.
[0026] Reference Figures 1 to 4 As shown, a height mark 8 is set on the conical positioning float 3, and the height data of the height mark 8 is half of the actual height value of the conical positioning float 3. A height mark 9 is set on the lock sleeve 6, and the height data of the height mark 9 is the actual height value of the lock sleeve 6. When adjusting the water depth, personnel only need to subtract the data of the height mark 8 and the height mark 9 from the sampling depth, so that the bottom of the lock sleeve 6 at the lower part of the conical positioning float 3 corresponds to the appropriate scale, thus facilitating the accurate adjustment of the position of the conical positioning float 3.
[0027] Reference Figures 1 to 4 As shown, a water inlet 10 is opened at the bottom of the sampling cylinder 1. A movable bottom plate 11 is arranged at the bottom of the inner cavity of the sampling cylinder 1. An L-shaped limiting convex plate 12 is arranged on the outer wall of the lower part of the inner cavity of the sampling cylinder 1. Two semi-circular flip covers 13 are movably connected to the top of the sampling cylinder 1. When the sampling sinks, water will enter the sampling cylinder 1 from the water inlet 10 and then be discharged from the upper opening of the sampling cylinder 1 until it reaches the specified water level. Then, personnel lift the sampling cylinder 1 upward. At this time, under the gravity of the water, the movable bottom plate 11 will seal the water inlet 10, so that the water can be lifted smoothly.
[0028] Reference Figures 1 to 4 As shown, a counterweight lead block 14 is fixedly connected to the outer wall of the lower part of the sampling cylinder 1. This structure uses the counterweight lead block 14 to ensure the stable sinking of the sampling cylinder 1.
[0029] Reference Figures 1 to 4 As shown, a water outlet pipe 15 is connected to the lower part of the sampling cylinder 1. A rubber pipe 16 is fixedly connected to the water outlet pipe 15, and a pipe clamp 17 is installed on the rubber pipe 16. After sampling, personnel can open the pipe clamp 17, so that the water in the sampling cylinder 1 will be discharged from the water outlet pipe 15 and the rubber pipe 16, thus facilitating transfer and storage.
[0030] The implementation principle of a water sampling device for water quality detection in an embodiment of this application is as follows: During use, before taking water, the operator adjusts the position of the conical positioning float 3 on the scale rope 2, thereby adjusting the conical positioning float 3 to a position corresponding to the water intake depth. Then, the conical positioning float 3 is fixed on the scale rope 2 through the compression bolt 7 on the locking sleeve 6. Then, the operator can put the sampling cylinder 1 into the water to take a sample. At this time, the cylindrical positioning float 3 will position the depth of the sampling cylinder 1 into the water, thus facilitating the positioning of the sampling water level. In this way, sampling will be more convenient, and the position of the conical positioning float 3 can be adjusted according to the sampling water depth, with good adjustment adaptability;
[0031] Moreover, in actual use, when the scale rope 2 slips out of the hand, the conical positioning float 3 can prevent the sampling cylinder 1 from sinking into the water, and plays a role in positioning, facilitating salvage, and avoiding accidental sinking and loss of the sampling cylinder 1.
[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
