Description

Technical Field

[0001] The utility model belongs to the technical field of hydrological monitoring, and in particular relates to a river sediment content monitoring device. Background Art

[0002] Rivers often carry a large amount of sediment, which is an important factor in river self-regulation. Sediment content analysis is the basic work in sediment research, mainly providing basic information for research on river evolution, water ecological environment, geological landforms, and soil erosion. Soil erosion refers to the destruction and loss of water and soil resources and land productivity under the influence of natural forces such as water, wind, gravity, and freeze-thaw and human activities, including land surface erosion and water loss. In order to control the soil erosion of rivers to a certain extent, it is necessary to sample and monitor the sediment content of rivers.

[0003] In the existing method of sampling river sediment, the sampling equipment is usually fixed by ropes and placed in the river, and then the river is sampled by the sampling equipment. Since the river is in a flowing state, it will carry the sediment at the bottom. During the sampling process, the sampling port is attached to the riverbed silt, which may easily cause the sediment content of the samples to be different, resulting in inaccurate monitoring of the sediment content.

DETAILED DESCRIPTION

[0025] This specific embodiment is a river sediment content monitoring device, and its structural schematic diagram is as follows Figure 1-Figure 6 As shown, the monitoring device comprises a column 1, a cross bar 2 is fixedly connected to the left side of the top of the column 1, a movable cylinder 3 is arranged on the left side of the cross bar 2 through a left-right adjustment component, a guide wheel 4 is installed on the left side of the movable cylinder 3, a lifting component 5 is arranged on the right side of the cross bar 2, a pull rope 6 is arranged at the output end of the lifting component 5, and a sampling component 7 is arranged on the left side of the pull rope 6 bypassing the guide wheel 4;

[0026] The sampling assembly 7 includes a sampling barrel 8, the bottom end of which is fixedly connected to a plurality of supporting legs 9, a barrel cover 10 is installed at the top end of the sampling barrel 8, a plurality of sampling ports 11 are opened on the barrel cover 10, a vertical rod 12 is slidably connected to the middle part of the barrel cover 10, the top end of the vertical rod 12 is fixedly connected to the pull rope 6 through a connecting piece 13, the bottom end of the vertical rod 12 is located inside the sampling barrel 8 and is fixedly connected to a sealing plate 14, the upper surface of the sealing plate 14 is fixedly connected to a first sealing gasket 15 corresponding to the sampling port 11, when the sampling barrel 8 is normally suspended in water, the pull rope 6 is in a taut state, and the vertical rod 12, the connecting piece 13, the sealing plate 14 and the first sealing gasket 15 connected to the pull rope 6 block the sampling port 11 on the barrel cover 10.

[0027] like Figure 1 and Figure 2 As shown: In this embodiment, a support rod 16 is fixedly connected to the left side of the column 1, and the other end of the support rod 16 is fixedly connected to the cross bar 2.

[0028] Such arrangement of the support rod 16 improves the structural strength between the upright column 1 and the cross bar 2 , and enables better sampling of river water through the sampling assembly 7 .

[0029] like Figure 1 and Figure 3 As shown: In this embodiment, the left and right adjustment components include a first motor 201 fixedly connected to the inside of the cross bar 2, the right end of the movable cylinder 3 is fixedly connected to the movable block 202, the movable block 202 is slidably connected to the inside of the cross bar 2, and the output end of the first motor 201 is fixedly connected to a screw rod 203, the screw rod 203 passes through the movable block 202 and is fixedly connected to the limiting block 204, and the screw rod 203 is threadedly connected to the movable block 202.

[0030] When sampling is set up in this way, the first motor 201 is started to drive the screw rod 203 to rotate. Since the screw rod 203 is threadedly connected to the movable block 202, the screw rod 203 can drive the movable block 202 and the movable cylinder 3 to move left during the rotation, thereby increasing the length of the movable cylinder 3 and the guide wheel 4 extending toward the river, so that the sampling component 7 extends to the middle of the river.

[0031] like Figure 1 and Figure 2 As shown: In this embodiment, a mounting groove 301 is opened on the left side of the movable cylinder 3, and the guide wheel 4 is rotatably connected in the mounting groove 301 through a pin shaft 302. In this way, the guide wheel 4 can guide the pull rope 6 to avoid tilting.

[0032] like Figure 3 and Figure 5As shown: In this embodiment, the lifting assembly 5 includes a fixed box 501 fixedly connected to the cross bar 2, a rotating shaft 502 is rotatably connected between the front and rear inner walls of the fixed box 501, a winding wheel 503 and a worm wheel 504 are fixedly connected to the outer surface of the rotating shaft 502, the right end of the pull rope 6 is wound around the outer surface of the winding wheel 503, a second motor 505 is fixedly connected to the right inner wall of the fixed box 501, a worm 506 is fixedly connected to the output end of the second motor 505, and the worm 506 is meshingly connected to the worm wheel 504.

[0033] This arrangement starts the second motor 505 to drive the worm 506 to rotate. During the rotation process, the worm 506 cooperates with the worm wheel 504 to drive the rotating shaft 502 and the winding wheel 503 to rotate slowly and loosen the pull rope 6. At this time, the sampling bucket 8 will sink to the bottom of the river due to its heavy weight, thereby facilitating sampling of the river.

[0034] like Figure 1 and Figure 6 As shown: In this embodiment, the support leg 9 is arranged at an angle, and a fixing block 901 is fixedly connected to the bottom end of the support leg 9.

[0035] In this arrangement, the sampling assembly 7 is in contact with the river bottom through the supporting legs 9 and the fixing block 901, and the sampling port 11 on the sampling barrel 8 is arranged on the upper side to avoid contact with silt. The sampled river water enters the sampling barrel 8 from the upper side, thereby making the sediment content in the sampled river water more accurate and better monitoring the sediment content in the river.

[0036] like Figure 1 and Figure 6 As shown: In this embodiment, an external thread 801 is provided on the outer surface of the top end of the sampling barrel 8, the barrel cover 10 is threadedly connected to the sampling barrel 8, and a second sealing gasket 1001 corresponding to the sampling barrel 8 is installed on the inner wall of the barrel cover 10.

[0037] In this way, the barrel cover 10 is opened to take out the sampled water containing sediment for testing. During sampling, the barrel cover 10 is threadedly connected to the sampling barrel 8, and the sealing is improved by the second sealing gasket 1001 to prevent river water from entering the sampling component 7 during the falling process.

[0038] Working principle: the column 1 is fixed on the bank of the river to be monitored. When sampling, the first motor 201 is started to drive the screw 203 to rotate. Since the screw 203 is threadedly connected to the movable block 202, the screw 203 can drive the movable block 202 and the movable cylinder 3 to move to the left during rotation, thereby increasing the length of the movable cylinder 3 and the guide wheel 4 extending to the river. Since the sampling barrel 8 is heavy, the vertical rod 12, the connecting piece 13, the sealing plate 14 and the first sealing gasket 15 connected with the pull rope 6 block the sampling port 11 on the barrel cover 10, and then the second motor 505 is started to drive the worm 506 to rotate. During the rotation, the worm 506 cooperates with the worm wheel 504 to drive the rotating shaft 502 and the winding wheel 503 to rotate slowly and relax the pull rope 6. At this time, As the sampling barrel 8 is heavy, it will sink to the bottom of the river. When the supporting legs 9 and the fixed block 901 at the bottom of the sampling barrel 8 touch the bottom of the river, they stop moving. At this time, the pull rope 6 continues to relax, and under the action of water pressure, the sealing plate 14 and the first sealing gasket 15 are pushed open, and the river water containing sediment enters the sampling barrel 8 along the sampling port 11, and then the second motor 505 is started to drive the worm 506 to reverse. During the rotation, the worm 506 cooperates with the worm gear 504 to drive the rotating shaft 502 and the winding wheel 503 to rotate slowly and tighten the pull rope 6. At this time, the pull rope 6 blocks the sampling port 11 on the barrel cover 10 through the vertical rod 12, the connecting piece 13, the sealing plate 14 and the first sealing gasket 15, and takes out the sampling barrel 8, and then opens the barrel cover 10 to take out the sampled water containing sediment for testing.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
