Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, specifically to a soil and water conservation water sampler. Background Art

[0002] Soil erosion refers to the phenomenon of simultaneous loss of water and soil due to natural or human factors, where rainwater cannot be absorbed locally and flows downstream, eroding the soil. The main causes include steep slopes, improper land use, destruction of vegetation, inadequate farming techniques, loose soil, and overgrazing. Soil erosion poses a serious threat to agricultural production in mountainous areas and downstream river channels. Therefore, in the process of monitoring soil erosion, it is often necessary to take water samples of a certain volume from canals and rivers to test the amount of sediment contained within, thus facilitating better management of soil erosion.

[0003] Currently, water erosion sampling devices typically use pumps and pipes to extract water from ditches. However, in practice, to ensure data diversity and accuracy, it is often necessary to collect water samples from different depths. But because the pipes are prone to floating and difficult to control, it is difficult to extend them into the water at the specified depth as needed. Furthermore, when extending them into the water, a large amount of water sample inevitably flows into the pipe, causing the water samples from different depths to mix, thus affecting the accuracy of the data results. Therefore, it is necessary to design a water erosion sampling device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a water sampler for soil erosion. By setting up a winding roller, guide wheel, connecting rope, and fixed cylinder, and controlling the unwinding length of the connecting rope, the depth of the fixed cylinder in the water can be steadily controlled. Furthermore, the fixed cylinder is equipped with a movable block, connecting rod, blocking block, and cover plate, allowing the connecting rod to move the cover plate up and down, thereby controlling the opening and closing of the bottom of the fixed cylinder. This enables the water sample to quickly fill the fixed cylinder, allowing for water sample collection at different depths as needed. It also effectively prevents the mixing of water samples from different depths, greatly improving the accuracy of water sample collection and addressing the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil erosion water sampler, comprising:

[0006] A fixed frame, wherein support frames are symmetrically arranged at both ends of the fixed frame, and a telescopic component is provided between the support frames and the fixed frame;

[0007] The L-shaped plate is fixedly connected to the top side of the fixed frame, and the side wall of the L-shaped plate is rotatably connected to the guide wheel via a rotating shaft. The bottom side of the fixed frame is rotatably mounted with a take-up roller, and the outer wall of the take-up roller is connected to a connecting rope. One end of the connecting rope is sleeved on the outside of the guide wheel and connected to a water intake mechanism.

[0008] The water intake mechanism includes a fixed cylinder with a waterproof cover at the top. A drive assembly is installed inside the waterproof cover. The output end of the drive assembly extends into the fixed cylinder and is connected to a movable block. A cover plate is installed at the bottom of the fixed cylinder. A blocking block matching the diameter of the fixed cylinder is fixed on the top side of the cover plate. Connecting rods are symmetrically connected to both ends of the movable block, and the bottom ends of the connecting rods are fixedly connected to the blocking blocks.

[0009] Preferably, the drive assembly includes a drive motor fixed inside a waterproof cover, the bottom end of the drive motor extending into the fixed cylinder and connected to a threaded post, the movable block being threadedly connected to the outside of the threaded post, and a limiting assembly being provided between the movable block and the fixed cylinder, with a stop block fixed at the bottom end of the threaded post.

[0010] Preferably, the limiting component includes limiting rods symmetrically fixed at both ends of the movable block, and the inner walls of the fixed cylinder are provided with limiting grooves facing the limiting rods on both sides, and the ends of the limiting rods are slidably fitted in the limiting grooves.

[0011] Preferably, a retaining ring is fixed on the top side of the cover plate and outside the block, and a retaining groove matching the retaining ring is provided at the bottom end of the fixing cylinder.

[0012] Preferably, a drive motor is fixed to the bottom side of the fixing frame, and the output end of the drive motor is connected to the take-up roller.

[0013] Preferably, the telescopic assembly includes two electric push rods symmetrically embedded at both ends of the fixed frame, and the output end of the electric push rod is fixedly connected to the support frame.

[0014] Preferably, both ends of the bottom side of the support frame are provided with casters.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By setting up a take-up roller, guide wheel, connecting rope, and fixed cylinder, and by controlling the unwinding length of the connecting rope, the rising and falling depth of the fixed cylinder in the water can be steadily controlled. Furthermore, by setting up structures such as movable blocks, connecting rods, blocking blocks, and cover plates on the fixed cylinder, the connecting rods can drive the cover plates to rise and fall, thereby controlling the opening and closing of the bottom of the fixed cylinder. This allows water samples to quickly fill the fixed cylinder, enabling water sample collection at different depths as needed, and effectively preventing the mixing of water samples from different depths, greatly improving the accuracy of water sample collection.

[0017] By setting retaining rings and grooves, the tightness of the connection between the fixed cylinder and the cover plate can be further enhanced, thereby greatly improving the sealing performance, effectively preventing water leakage or seepage, and ensuring high safety.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5 A soil erosion water sampling device is shown, comprising:

[0028] The fixed frame 3 has support frames 1 symmetrically arranged at both ends, and a telescopic component is provided between the support frames 1 and the fixed frame 3;

[0029] The telescopic assembly includes two electric push rods 4 symmetrically embedded at both ends of the fixed frame 3, and the output end of the electric push rod 4 is fixedly connected to the support frame 1.

[0030] By setting an electric push rod 4, the electric push rod 4 can drive the fixed frame 3 to move, thereby adjusting the distance between the two support frames 1 and the fixed frame 3, so that the two support frames 1 can be erected on both sides of the road of the water channel, so that the device can be erected above water channels of different widths.

[0031] Both ends of the bottom side of the support frame 1 are equipped with casters 2. The casters 2 facilitate the movement of the device.

[0032] L-shaped plate 5 is fixedly connected to the top side of the fixed frame 3, and the side wall of L-shaped plate 5 is rotatably connected to guide wheel 6 through a rotating shaft. A take-up roller 7 is rotatably installed on the bottom side of the fixed frame 3. A connecting rope 8 is connected to the outer wall of the take-up roller 7. One end of the connecting rope 8 is sleeved on the outside of the guide wheel 6 and connected to a water intake mechanism.

[0033] A drive motor 11 is fixed to the bottom side of the fixed frame 3, and the output end of the drive motor 11 is connected to the take-up roller 7.

[0034] The winding roller 7 is driven by the drive motor 11 to rotate, which can cause the winding roller 7 to wind up and unwind the connecting rope 8. Under the guidance of the guide wheel 6, the connecting rope 8 can drive the fixed cylinder 10 to rise and fall, so as to drive the fixed cylinder 10 to rise and fall in the water. The outer wall of the connecting rope 8 can also be set with scale lines to accurately determine the water depth.

[0035] The water intake mechanism includes a fixed cylinder 10, a waterproof cover 9 at the top of the fixed cylinder 10, a drive assembly inside the waterproof cover 9, the output end of the drive assembly extending into the fixed cylinder 10 and connected to a movable block 14, a cover plate 18 installed at the bottom of the fixed cylinder 10, a block 17 matching the diameter of the fixed cylinder 10 fixed on the top side of the cover plate 18, and connecting rods 16 symmetrically connected to both ends of the movable block 14, with the bottom end of the connecting rod 16 fixedly connected to the block 17.

[0036] The drive assembly includes a drive motor 12 fixed inside the waterproof cover 9. The bottom end of the drive motor 12 extends into the fixed cylinder 10 and is connected to a threaded post 13. The movable block 14 is connected to the outside of the threaded post 13 by threaded engagement, and a limiting component is provided between the movable block 14 and the fixed cylinder 10. A stop block 15 is fixed to the bottom end of the threaded post 13.

[0037] The limiting assembly includes limiting rods 21 symmetrically fixed at both ends of the movable block 14. The inner walls of the fixed cylinder 10 are provided with limiting grooves 22 facing the limiting rods 21, and the ends of the limiting rods 21 are slidably fitted in the limiting grooves 22.

[0038] In use, the device can be erected above a water channel. The drive motor 11 drives the take-up roller 7 to rotate, and with the cooperation of the guide wheel 6, the connecting rope 8 lowers the fixed cylinder 10, causing it to submerge in the water. The fixed cylinder 10 has a certain weight; by controlling the unwinding length of the connecting rope 8, the descent of the fixed cylinder 10 in the water can be controlled steadily. Once it reaches the designated depth, the drive motor 12 can be activated, causing the threaded column 13 to rotate. The threaded column 13 then drives the movable block 14 to move. With the cooperation of the limiting components, the device can... The movable block 14 moves along a straight line, causing the connecting rods 16 on both sides to descend. This causes the connecting rods 16 to lower the blocking block 17, which in turn causes the blocking block 17 to disengage the cover plate 18 from the fixed cylinder 10. This allows water samples to flow into the fixed cylinder 10. Then, by controlling the movable block 14 to raise the connecting rods 16, the connecting rods 16 can be reset, causing the blocking block 17 and cover plate 18 to be reset. This allows the fixed cylinder 10 to be sealed again, enabling water sample collection at different depths as needed. It also effectively prevents the mixing of water samples from different depths, greatly improving the accuracy of water sample collection.

[0039] A retaining ring 19 is fixed on the top side of the cover plate 18 and outside the block 17, and a retaining groove 20 matching the retaining ring 19 is opened at the bottom end of the fixing cylinder 10.

[0040] By interlocking the retaining ring 19 with the retaining groove 20, the tightness of the connection between the fixed cylinder 10 and the cover plate 18 can be further enhanced, thereby greatly improving the sealing performance, effectively preventing water leakage or seepage, and ensuring high safety.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
