Description

Technical Field

[0001] This utility model relates to the field of sediment depth measurement technology, and in particular to a river sediment depth measurement device for hydrological surveying. Background Technology

[0002] Hydrological surveying is an integral part of water conservancy science. Severe siltation in river channels can affect the hydraulic conditions of the river, leading to obstructed water flow and increasing the risk of floods and sediment accumulation. Therefore, measuring the sediment depth in rivers is an important indicator when conducting hydrological surveys.

[0003] Currently, the methods for measuring river sediment depth are generally sampling and acoustic detection. However, acoustic detection is susceptible to interference, as suspended matter or air bubbles in the water cause sound wave scattering. Sampling methods typically involve bulky equipment, and sediment can easily fall out when the sample is removed from the column sampler, affecting measurement accuracy. Furthermore, the inside of the column sampler is inconvenient to clean after use. Therefore, it is necessary to design a river sediment depth measurement device for hydrological surveys. Utility Model Content

[0004] The main purpose of this invention is to provide a river sediment depth measurement device for hydrological surveying, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A river sediment depth measuring device for hydrological surveying includes a cylindrical body. A fixed plate is fixedly connected to the bottom end of the cylindrical body. A through groove is formed on the inner surface of the fixed plate. A limiting groove is formed on the lower surface of the fixed plate. A limiting plate is slidably connected to the inner wall of the limiting groove. A fixing column is fixedly connected to the outer surface of the limiting plate. A limiting ring is rotatably connected to the lower surface of the fixed plate. A fixing groove is formed on the outer surface of the limiting ring. The fixing column is movably connected to the fixing groove. A fixed disc is provided on the outer surface of the cylindrical body. A handle disc is rotatably connected to the inner surface of the fixed disc. A connecting rod is fixedly connected to one side of the outer surface of the handle disc. The connecting rod is fixedly connected to the limiting ring. An observation window and scale lines are provided on the outer surface of the cylindrical body.

[0007] In order to enable the piston block to move, as a river sediment depth measuring device for hydrological surveying according to this utility model, the inner wall of the cylinder is slidably connected to the piston block, and the top of the piston block is fixedly connected to the push-pull rod.

[0008] To facilitate the movement of the push-pull rod, as a river sediment depth measuring device for hydrological surveying according to this utility model, a connecting plate is fixedly connected to the top of the push-pull rod, and a top groove is opened on one side of the outer surface of the push-pull rod.

[0009] In order to fix the position of the push-pull rod, as a river sediment depth measuring device for hydrological survey of this utility model, a bolt is threaded on one side of the outer surface of the cylinder, and one end of the bolt penetrates the outer surface of the cylinder and extends to the inner surface of the cylinder.

[0010] To prevent the push-pull rod from tilting, as a river sediment depth measuring device for hydrological surveying according to this utility model, a top plate is fixedly connected to the inner surface of the cylinder, and the top plate is slidably connected to the top groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting up a cylinder, a fixed plate, a limiting groove, and a scale line, rotating the handle plate on the fixed disc can drive the limiting ring to rotate via the connecting rod. When the limiting ring rotates, the fixed groove on it can drive the fixed post on the limiting plate to move within the fixed groove, thereby allowing multiple limiting plates to slide along the limiting groove, thus exposing the through groove. At this time, pressing down on the cylinder will push the cylinder deeper into the river silt, and the silt will enter the cylinder through the through groove. Rotating the handle plate in the opposite direction will similarly close the through groove. At this time, the height of the silt inside the cylinder is the depth of the river silt, which can be observed through the observation window and counted using the scale line.

[0013] 2. In this utility model, through the arrangement of the cylinder, piston block, push-pull rod, connecting plate and top plate, when in use, after the cylinder is filled with mud and sand and the scale line is observed and counted, the handle plate is rotated to move the limiting plate to expose the through groove, and then the connecting plate is pressed down. The connecting plate drives the push-pull rod and piston block to move down to push the mud and sand out of the cylinder, which is convenient for cleaning the inside of the cylinder after the mud and sand measurement. When the push-pull rod moves, the top plate and the top groove slide. When the bolt is tightened, the position of the push-pull rod can be fixed by the action of the bolt. At this time, the push-pull rod can be prevented from tilting by the pushing of the top plate against the top groove. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-6 As shown, a river sediment depth measuring device for hydrological survey includes a cylinder 1, a fixed plate 2 fixedly connected to the bottom end of the cylinder 1, a through groove 3 opened on the inner surface of the fixed plate 2, a limiting groove 4 opened on the lower surface of the fixed plate 2, a limiting plate 5 slidably connected to the inner wall of the limiting groove 4, a fixed column 6 fixedly connected to the outer surface of the limiting plate 5, a limiting ring 7 rotatably connected to the lower surface of the fixed plate 2, a fixing groove 8 opened on the outer surface of the limiting ring 7, and the fixing column 6 movably connected to the fixing groove 8.

[0023] In this embodiment, a fixed disc 9 is provided on the outer surface of the cylinder 1, and a handrail disc 10 is rotatably connected to the inner surface of the fixed disc 9. A connecting rod 11 is fixedly connected to one side of the outer surface of the handrail disc 10. The connecting rod 11 is fixedly connected to the limiting ring 7. An observation window 12 is provided on the outer surface of the cylinder 1, and a scale line 13 is provided on the outer surface of the cylinder 1.

[0024] In practical use, rotating the handle plate 10 on the fixed disc 9 can drive the rotation of the limiting ring 7 through the connecting rod 11. When the limiting ring 7 rotates, the fixed groove 8 on it can drive the fixed post 6 on the limiting plate 5 to move in the fixed groove 8, so that multiple limiting plates 5 can slide along the limiting groove 4, thereby exposing the through groove 3. At this time, press down on the cylinder 1 to insert the cylinder 1 into the river silt. The silt enters the cylinder 1 through the through groove 3. Rotate the handle plate 10 in the opposite direction to close the through groove 3. At this time, the height of the silt inside the cylinder 1 is the depth of the river silt, which can be observed through the observation window 12 and counted through the scale line 13.

[0025] In this embodiment, a piston block 14 is slidably connected to the inner wall of the cylinder 1, and a push-pull rod 15 is fixedly connected to the top of the piston block 14.

[0026] In practical use, the push-pull rod 15 can move the piston block 14 when it moves up and down. The piston block 14 can easily push out the mud and sand in the cylinder 1.

[0027] In this embodiment, a connecting plate 16 is fixedly connected to the top of the push-pull rod 15, and a top groove 17 is provided on one side of the outer surface of the push-pull rod 15.

[0028] In actual use, pressing or pulling the connecting plate 16 can drive the push-pull rod 15 and the piston block 14 to move.

[0029] In this embodiment, a bolt 18 is threadedly connected to one side of the outer surface of the cylinder 1, and one end of the bolt 18 penetrates the outer surface of the cylinder 1 and extends to the inner surface of the cylinder 1.

[0030] In practical use, when tightening bolt 18, one end of bolt 18 can press against push-pull rod 15 and fix the position of push-pull rod 15.

[0031] In this embodiment, a top plate 19 is fixedly connected to the inner surface of the cylinder 1, and the top plate 19 is slidably connected to the top groove 17.

[0032] In practical use, when the bolt 18 fixes the position of the push-pull rod 15, the top plate 19 can push the top groove 17, which can ensure that the push-pull rod 15 will not tilt when the bolt 18 fixes the push-pull rod 15.

[0033] Working principle: During use, rotating the handle plate 10 on the fixed disc 9 can drive the rotation of the limiting ring 7 via the connecting rod 11. When the limiting ring 7 rotates, its fixed groove 8 can drive the fixed post 6 on the limiting plate 5 to move within the fixed groove 8, thereby allowing multiple limiting plates 5 to slide along the limiting groove 4, thus exposing the through groove 3. At this time, pressing down on the cylinder 1 will push the cylinder 1 deeper into the river silt. The silt enters the cylinder 1 through the through groove 3. Rotating the handle plate 10 in the opposite direction will similarly close the through groove 3. At this time, the height of the silt inside the cylinder 1 is the depth of the river silt, which can be observed through the observation window 12. After counting by observing the scale line 13, and after the cylinder 1 is filled with mud and sand, rotate the handle plate 10 to move the limit plate 5 to expose the through groove 3, and then press down the connecting plate 16. The connecting plate 16 drives the push-pull rod 15 and the piston block 14 to move down and push the mud and sand out of the cylinder 1, which is convenient for cleaning the inside of the cylinder 1 after the mud and sand measurement. When the push-pull rod 15 moves, the top plate 19 and the top groove 17 slide. When the bolt 18 is tightened, the push-pull rod 15 can be fixed in position by the action of the bolt 18. At this time, the push of the top plate 19 against the top groove 17 can prevent the push-pull rod 15 from tilting.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
