Description

Technical Field

[0001] This utility model relates to the field of runoff plot technology, and more specifically, to a collection tank for hydraulic erosion runoff plots. Background Technology

[0002] Hydraulic erosion is the entire process by which soil, soil bodies, or other ground components are destroyed, eroded, transported, and deposited under the influence of precipitation, surface runoff, and groundwater runoff. A runoff plot is a testing facility used to quantitatively study the patterns of soil erosion on slopes and in small watersheds. It generally consists of a embankment, a plot enclosed by the embankment, a catchment channel, runoff and sediment collection tanks, a protective belt, and a drainage system.

[0003] A search revealed that utility model patent CN208333975U discloses a collection tank for a water erosion runoff area. The tank includes a main body with a stirring mechanism fixed inside. A sampling port is located at the top of the main body, and a sampling device is fixed inside the sampling port. The stirring mechanism prevents sediment settling and stratification, ensuring thorough mixing of sediment and water and improving sampling accuracy. The sampling device can extract samples from different locations inside the main body, further improving sampling accuracy and ensuring precise test results.

[0004] However, the aforementioned patents have the following shortcomings: they require an additional high-pressure gas source to supply gas to the stirring mechanism, which restricts the convenience of using the collection tank; and sampling needs to be performed multiple times, which is not very convenient. To address this, we propose a collection tank for hydraulic erosion runoff in small communities. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a collection tank for water erosion runoff in a small area.

[0006] To solve the above problems, the present invention adopts the following technical solution: a collection tank for water erosion runoff in a small area, comprising a tank body, a tripod fixedly connected to the top of the inner cavity of the tank body, an insertion hole in the middle of the tripod, a sampling mechanism provided in the inner cavity of the insertion hole, three rotating rods rotatably connected to the tripod, the bottom ends of the three rotating rods extending to the bottom of the inner cavity of the tank body and fixedly connected to multiple stirring plates, a turntable fixedly connected to the top of each rotating rod, a handle fixedly connected to the top surface of each turntable, a synchronous pulley fixedly sleeved on the side of the top of each of the three rotating rods, and a synchronous belt drivingly connected to the outer side of the three synchronous pulleys.

[0007] As a preferred embodiment of this utility model, the sampling mechanism includes a sampling cylinder sleeved in the inner cavity of the insertion hole. The bottom surface of the sampling cylinder is in contact with the bottom surface of the inner cavity of the tank. The sampling cylinder is provided with multiple sampling slots. Sampling holes are opened on the side of the bottom of the inner cavity of each of the multiple sampling slots. A piston plate is movably sleeved in the inner cavity of each of the multiple sampling slots. The side of the piston plate is in contact with the inner wall of the sampling slot. A pull rod is movably sleeved in the inner cavity of the sampling cylinder. The pull rod passes through the inner cavity of the sampling slot and is fixedly sleeved with multiple piston plates respectively. The top end of the pull rod extends to the top of the sampling cylinder and is fixedly connected to a pull plate. A scale is provided on the side of the sampling cylinder.

[0008] As a preferred embodiment of this utility model, the sampling tube is provided with a vent hole inside, the top of the vent hole is connected to the top surface of the sampling tube, and the sides of the top of the inner cavity of the plurality of sampling slots are provided with vent holes, the ends of the vent holes are connected to the inner cavity of the vent hole.

[0009] As a preferred embodiment of this utility model, the top surface of the tripod and the side of the insertion hole are provided with three arc-shaped card seats, and the top side of the sampling tube is fixedly connected with three card blocks, and the three card blocks are respectively sleeved in the inner cavity of the three arc-shaped card seats.

[0010] As a preferred embodiment of this utility model, a triangular protective shell is fixedly connected to the top surface of the tripod, and the triangular protective shell is sleeved on the outside of the synchronous pulley and the synchronous belt.

[0011] As a preferred embodiment of this utility model, a switch valve is fixedly installed on the side of the tank, and the end of the switch valve extends to the bottom of the inner cavity of the tank.

[0012] In a preferred embodiment of this utility model, the inner diameter of the insertion hole is equal to the outer diameter of the sampling tube.

[0013] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, a handle is held to drive a rotating rod and a synchronous wheel to rotate. The transmission between the synchronous wheel and the synchronous belt drives multiple rotating rods to rotate synchronously. Multiple stirring plates on the sides of the multiple rotating rods are used to stir the mud-water mixture in the inner cavity of the tank, so as to avoid the sedimentation of the mud-water mixture collected in the inner cavity of the tank from affecting the quality of sampling and testing. At the same time, it realizes the function of manually stirring the mud-water mixture in the inner cavity of the tank.

[0014] In this invention, during sampling, the sampling tube is inserted into the insertion hole, and the bottom surface of the sampling tube is made to fit against the bottom surface of the inner cavity of the tank. By pulling the pull plate upward, the pull rod is moved upward, and the pull rod drives multiple piston plates to move upward in the inner cavity of multiple sampling slots. The negative pressure in the lower part of the inner cavity of the sampling slot is used to draw the mud-water mixture in the inner cavity of the tank into the sampling hole, realizing the function of sampling mud-water mixture at different heights in the inner cavity of the tank in one go, which has good practicality.

The top end of the pull rod 17 extends to the top of the sampling cylinder 13 and is fixedly connected to a pull plate 18. A scale 19 is provided on the side of the sampling cylinder 13.

[0029] In this embodiment, the sampling tube 13 can be made of transparent material so that the mud and sand mixture collected in the sampling trough 14 can be viewed. In addition, the height of the multiple sampling troughs 14 is measured using a ruler 19, and the mud and sand mixture at different depths inside the tank 1 is sampled and tested using the multiple sampling troughs 14.

[0030] For details, please refer to Figures 5 to 7 The sampling cylinder 13 has a vent 20 inside, and the top of the vent 20 is connected to the top surface of the sampling cylinder 13. The sides of the top of the inner cavity of the multiple sampling slots 14 are provided with vent holes 21, and the ends of the vent holes 21 are connected to the inner cavity of the vent holes 20.

[0031] In this embodiment, the cooperation of the vent 20 and the air vent 21 avoids the generation of high pressure or negative pressure in the upper part of the sampling groove 14, ensuring that the piston plate 16 can move smoothly up and down in the inner cavity of the sampling groove 14.

[0032] For details, please refer to Figures 2 to 5 Three arc-shaped card holders 23 are provided on the top surface of the tripod 2 and on the side of the insertion hole 12. Three card blocks 22 are fixedly connected to the side of the top of the sampling tube 13.

[0034] For details, please refer to Figures 1 to 3 The top surface of the tripod 2 is fixedly connected to a triangular protective shell 10, which is fitted onto the outside of the synchronous pulley 8 and the synchronous belt 9.

[0036] For details, please refer to Figure 1A switch valve 11 is fixedly installed on the side of the tank body 1, and the end of the switch valve 11 extends to the bottom of the inner cavity of the tank body 1.

[0037] In this embodiment, the sand-water mixture collected in the inner cavity of the tank 1 is discharged through the switch valve 11.

[0038] For details, please refer to Figure 3 and Figure 5 The inner diameter of the jack 12 is equal to the outer diameter of the sampling tube 13.

[0039] In this embodiment, the stability of the sampling tube 13 being fitted into the cavity of the insertion hole 12 is ensured.

[0040] Working principle: In use, the tank 1 is first used to collect the mud and water generated from the hydraulic erosion runoff plot test. Then, when sampling, the sampling tube 13 is inserted into the insertion hole 12, and the sampling tube 13 is rotated so that the locking block 22 at the top of the tube engages with the inside of the arc-shaped locking seat 23, thereby fixing the sampling tube 13. One of the handles 7 is held to drive a turntable 6 to rotate, which in turn drives a synchronous wheel 8 and a rotating rod 4 to rotate. The transmission between the three synchronous wheels 8 and the synchronous belt 9 drives the three rotating rods 4 to rotate synchronously. The stirring plate 5 on the side of the rotating rod 4 agitates the mud and water mixture inside the tank 1. Then, the pull plate 18 is pulled upward to move the pull rod 17 upward. The pull rod 17 drives multiple piston plates 16 to move upward within the inner cavities of multiple sampling slots 14. The negative pressure at the lower part of the inner cavity of the sampling slot 14 draws the mud-water mixture from the inner cavity of the tank 1 into the sampling hole 15, thereby sampling the mud-water mixture at different heights within the inner cavity of the tank 1. Finally, the sampling cylinder 13 is rotated to move the locking block 22 out from the inner side of the arc-shaped locking seat 23, releasing the fixation of the sampling cylinder 13 so that it can be pulled out from the inner cavity of the insertion hole 12. The pull plate 18 is pushed in the opposite direction, causing the pull rod 17 and piston plates 16 to move in the opposite direction, so that the mud-water mixture collected in the multiple sampling slots 14 is discharged from the sampling hole 15. The mud-water mixture discharged from the multiple sampling holes 15 can then be tested.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
