Description

Technical Field

[0001] This utility model relates to the field of river water sampling technology, specifically to a sand sampling device. Background Technology

[0002] The Yellow River diversion sluice gates under the jurisdiction of the River Affairs Bureau have a large water diversion volume, amounting to 1.2 billion cubic meters annually, which increases the workload of water sampling. The existing horizontal sampler is outdated, bulky, and inconvenient to operate. The horizontal sampler has a cylindrical body with its axis parallel to the water flow direction, and both ends are covered with springs. During sampling, both covers are opened, and once the water flow stabilizes, a switch is operated to close both covers simultaneously, obtaining an instantaneous water sample. This type of sampler is simple to operate and highly adaptable, but it is affected by sediment pulsations, resulting in poor representativeness of the water samples. The horizontal sampler is no longer suitable for sediment sampling work. Utility Model Content

[0003] The main objective of this invention is to provide a sand sampler that is simple and convenient to operate, effectively reduces operational errors, and improves the accuracy of sand content measurement. This sand sampler is portable, facilitates fixed-point sampling, and can achieve depth sampling during uniform descent in water, making it widely applicable.

[0004] A sand sampler includes a cylindrical body with a handle rotatably connected to the upper end. An inlet is located at the lower end of the cylindrical body, and a corresponding one-way opening component is installed inside the body. When the cylindrical body sinks in water, the one-way opening component opens under water pressure, allowing water to enter the body through the inlet. An outlet is located at the upper end of the cylindrical body, and a corresponding one-way opening component is installed there. When the cylindrical body sinks in water, the one-way opening component opens, allowing water to drain from the outlet. When the cylindrical body rises in water, both the one-way and one-way opening components close, sealing the inlet and outlet. A counterweight ring is concentrically fixed to the lower end of the cylindrical body, and a water outlet pipe is fixed to the lower end of the side wall of the cylindrical body, communicating with the cylindrical body. A valve is installed on the water outlet pipe. The first end of a pull rope is fixedly connected to the handle, and graduations are marked along the length of the pull rope.

[0005] Specifically, the lower one-way opening component includes a lower rubber pad, the lower end face of which is in sealing contact with the upper end face of the bottom plate of the cylinder and blocks the inlet hole, one side of the lower rubber pad is fixed to the bottom plate of the cylinder, and a lower cover is fixed to the upper end of the lower rubber pad.

[0006] Specifically, the upper one-way opening component includes an upper rubber pad, the lower end face of which is in sealing contact with the upper end face of the top plate of the cylinder and blocks the outlet hole, one side of the upper rubber pad is fixed to the top plate of the cylinder, and an upper cover is fixed to the upper end of the upper rubber pad.

[0007] Specifically, an inner rod is fixed inside the cylinder, and a top rod is slidably mounted on the inner rod. The top rod can slide in the axial direction of the cylinder. The upper end of the top rod contacts the lower end of the upper rubber pad, and the lower end of the top rod contacts the upper end of the lower cover.

[0008] Specifically, a fixed column is fixed to the upper end of the top plate of the cylinder, and a rotating plate is rotatably connected to the fixed column. The first end of the rotating plate is connected to the second end of the pull rope. After the pull rope pulls the rotating plate to rotate, the second end of the rotating plate can press tightly against the upper end of the cover and restrict the rotation of the cover.

[0009] Specifically, the axial direction of the fixed column is parallel to the axial direction of the cylinder, and a rotating rod is rotatably connected to the fixed column. The rotating rod is perpendicular to the fixed column, and a rotating plate passes through the rotating rod. The rotating plate and the rotating rod are fixedly connected.

[0010] Specifically, a pull ring is rotatably connected to the first end of the rotating plate, and the pull ring is fixedly connected to the second end of the pull rope.

[0011] Specifically, the upper and lower covers are made of engineering plastics.

[0012] 1. This sand sampler is portable and facilitates fixed-point sampling of river water.

[0013] 2. During the downward movement of this sand sampler in water, water enters the cylinder through the inlet and exits through the outlet. This sand sampler can achieve depth sampling during the uniform descent in water.

[0014] 3. When lifting the sand sampler, both the inlet and outlet holes are closed to prevent water samples from spilling out of the cylinder, thus ensuring a high sampling success rate.

[0015] 4. The rope is equipped with graduation lines to facilitate fixed-depth sampling.

[0016] 5. After the pull rope pulls the rotating plate, the second end of the rotating plate can press tightly against the upper end of the upper cover and restrict the rotation of the upper cover. The upper cover and the upper rubber pad press tightly against the lower cover and the lower rubber pad through the top rod, which can ensure the sealing effect of the inlet and outlet holes and prevent mud and sand from accumulating on the sealing surface that mates with the upper and lower rubber pads, causing water leakage inside the cylinder.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-5 As shown, the sand sampler includes a cylinder 1, with a handle 4 rotatably connected to the upper end of the cylinder 1 and an inlet hole 16 at the lower end of the cylinder 1. A one-way opening component corresponding to the inlet hole 16 is provided inside the cylinder 1. When the cylinder 1 sinks in water, the one-way opening component is opened by water pressure, and water enters the cylinder 1 through the inlet hole 16.

[0025] The lower one-way opening component includes a lower rubber pad 12. The lower end face of the lower rubber pad 12 is in sealing contact with the upper end face of the bottom plate of the cylinder 1 and blocks the inlet hole 16. One side of the lower rubber pad 12 is fixed to the bottom plate of the cylinder 1, and a lower cover 13 is fixed to the upper end of the lower rubber pad 12.

[0026] The upper end of the cylinder 1 is provided with an outlet hole 17, and the upper end of the cylinder 1 is provided with an upper one-way opening component corresponding to the outlet hole 17. When the cylinder 1 sinks in the water, the upper one-way opening component opens, and the water in the cylinder 1 is discharged from the outlet hole 17.

[0027] The upper one-way opening component includes an upper rubber pad 6. The lower end face of the upper rubber pad 6 is in sealing contact with the upper end face of the top plate of the cylinder 1 and blocks the outlet hole 17. One side of the upper rubber pad 6 is fixed to the top plate of the cylinder 1, and an upper cover 5 is fixed to the upper end of the upper rubber pad 6.

[0028] The top cover 5 and the bottom cover 13 are made of engineering plastic.

[0029] When the cylinder 1 moves upward in the water, the upper one-way opening component and the lower one-way opening component are closed, and the inlet hole 16 and the outlet hole 17 are blocked.

[0030] A counterweight ring 2 is concentrically fixed at the lower end of the cylinder 1. The weight of the counterweight ring 2 ensures the downward speed of the cylinder 1 in the water.

[0031] A water outlet pipe 3 is fixed at the lower end of the side wall of the cylinder 1. The water outlet pipe 3 is connected to the cylinder 1 and a valve is installed on the water outlet pipe 3.

[0032] The first end of the pull rope 11 is fixedly connected to the handle 4, and scale lines are provided on the pull rope 11 along its length.

[0033] In this embodiment, as the cylinder 1 descends in the water after the release of the pull rope 11, the water pushes the lower rubber pad 12 and the lower cover 13 to rotate upwards. Water enters the cylinder 1 through the inlet 16. When the cylinder 1 is fully submerged, as it continues to sink, the water inside pushes the upper rubber pad 6 and the upper cover 5 to rotate and exit through the outlet 17. Depth sampling can be achieved during the uniform descent of the cylinder 1 in the water.

[0034] The descent depth of cylinder 1 can be determined by the scale lines on the pull rope 11. Once cylinder 1 reaches the designated depth, it is pulled upwards using the pull rope 11. As cylinder 1 ascends in the water, the upper cover 5 and upper rubber pad 6 seal the outlet hole 17, and the lower cover 13 and lower rubber pad 12 seal the inlet hole 16. After pulling cylinder 1 out of the water, the valve is opened, allowing the water sample in cylinder 1 to be discharged, facilitating the detection of sand content.

[0035] Example 2: Based on Example 1, referring to... Figures 1-5 As shown, an inner rod 14 is fixed inside the cylinder 1, and a top rod 15 is slidably arranged on the inner rod 14. The top rod 15 can slide in the axial direction of the cylinder 1. The upper end of the top rod 15 contacts the lower end of the upper rubber pad 6, and the lower end of the top rod 15 contacts the upper end of the lower cover 13.

[0036] A fixing post 7 is fixed to the upper end of the top plate of the cylinder 1. A rotating plate 9 is rotatably connected to the fixing post 7. The first end of the rotating plate 9 is connected to the second end of the pull rope 11. After the pull rope 11 pulls the rotating plate 9 to rotate, the second end of the rotating plate 9 can press tightly against the upper end of the cover 5 and restrict the rotation of the cover 5.

[0037] Specifically, the axial direction of the fixed column 7 is parallel to the axial direction of the cylinder 1. A rotating rod 8 is rotatably connected to the fixed column 7, and the rotating rod 8 is perpendicular to the fixed column 7. A rotating plate 9 passes through the rotating rod 8, and the rotating plate 9 is fixedly connected to the rotating rod 8. A pull ring 10 is rotatably connected to the first end of the rotating plate 9, and the pull ring 10 is fixedly connected to the second end of the pull rope 11.

[0038] In this embodiment, after the pull rope 11 is tightened, the outer side of the pull rope 11 connected to the pull ring 10, defined by the curved portion of the pull rope 11, can be coated with color.

[0039] When the cylinder 1 descends, the uncolored part of the pull rope 11 is pulled, so that the colored part of the pull rope 11 remains slack. This prevents the rotating rod 8 from affecting the rotation of the upper cover 5 and the upper rubber pad 6 when the cylinder 1 descends in the water.

[0040] Once the cylinder 1 reaches the designated depth, the colored pull rope 11 can be pulled. When the colored pull rope 11 is tightened, the second end of the rotating plate 9 can press tightly against the upper end of the upper cover 5 and restrict the rotation of the upper cover 5. The upper cover 5 and the upper rubber gasket 6 are pressed tightly against the lower cover 13 and the lower rubber gasket 12 through the top rod 15, which can ensure the sealing effect of the inlet hole 16 and the outlet hole 17, and prevent mud and sand from accumulating on the sealing surfaces that mate with the upper rubber gasket 6 and the lower rubber gasket 12, causing water sample leakage inside the cylinder 1.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
