Description

Technical Field

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

[0002] Currently, the suspended sediment content in rivers is fundamental information for the design of water conservancy projects, the evaluation of soil and water conservation effects, and the operation and management of projects. It is the basis for evaluating the degree of damage and restoration of the underlying surface of a watershed or region. Its measurement is a key issue in sediment dynamics research and nearshore engineering, and it is also an important part of hydrological observation.

[0003] Traditional suspended sediment testing typically involves operators taking a certain amount of river water samples, which then undergo tedious processes such as filtration, drying, and weighing. This method consumes a lot of manpower and resources and is inconvenient to operate. On the one hand, when the river water level is high and the water flow is fast, it is difficult for operators to collect samples, and there are also risks involved in sampling.

[0004] On the other hand, the sampling obtains the instantaneous concentration of sediment, which means that the river water is not continuous in time and cannot reflect the real-time changes in sediment. Therefore, the amount of sediment cannot be used to accurately monitor soil erosion. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a sediment measuring device, which can draw river water through a water pump and enter the flow pool through the water inlet pipe, and stir the water flow in the flow chamber with a water flow propeller, so that the sediment detector can measure the sediment in the flowing water.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A sediment measuring device, comprising,

[0008] A flow-through tank is provided with a flow-through cavity, an inlet, an outlet, an inlet pipe, and an outlet pipe. The inlet is connected to one end of the flow-through cavity, the outlet is connected to the other end of the flow-through cavity, the inlet pipe is connected to the inlet, and the outlet pipe is connected to the outlet.

[0009] A water pump is installed in the flow tank and is used to provide water flow power to guide water flow through the inlet pipe into the flow chamber.

[0010] A sediment detection assembly includes a sediment detector and a detection bracket. The bottom end of the detection bracket is connected to the bottom wall of the flow cavity, and a support plate is provided at the top end of the detection bracket. The sediment detector is installed on the support plate and is used to detect sediment in the flow cavity.

[0011] A water jet propulsion device is used to agitate the water flow within the flow chamber.

[0012] Furthermore, two water jet propellers are provided, which are located at both ends of the flow cavity along its length and staggered along its width.

[0013] Furthermore, the water propulsion device includes a propulsion motor and a rotating component, the rotating component being provided with helical blades; the propulsion motor drives the rotating component to rotate.

[0014] Furthermore, the bottom wall of the flow cavity includes a first bottom wall and a second bottom wall, the first bottom wall and the second bottom wall are offset in the height direction, and the first bottom wall is higher than the second bottom wall. The first bottom wall surrounds the periphery of the second bottom wall, and the first bottom wall and the second bottom wall are connected by an inclined surface; the water outlet is disposed on the second bottom wall.

[0015] Furthermore, the top sidewall of the flow pool is provided with an overflow outlet and an overflow pipe, and the overflow outlet is connected to the top of the flow cavity.

[0016] Furthermore, the top of the flow pool is covered with a transparent plate, which is detachably covered on the top of the flow cavity; the transparent plate is provided with multiple dry assembly holes.

[0017] Furthermore, the detection bracket includes multiple support tubes and multiple support plates, with the multiple support tubes spaced apart along the length of the flow cell; the multiple support plates are installed one-to-one at the top of the multiple support tubes and are used to support the sediment detector.

[0018] Furthermore, both sides of the support plate are provided with upwardly bent baffles.

[0019] Furthermore, the inlet pipe is equipped with a first solenoid valve, and the outlet pipe is equipped with a second solenoid valve.

[0020] Furthermore, a plurality of mounting blocks are provided on the side wall of the flow pool, and the plurality of mounting blocks are distributed at intervals in the height direction of the flow pool; the mounting blocks are provided with mounting grooves.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] To detect the sediment content in the water flow, the water flow propeller is activated. The propeller agitates the water flow within the flow chamber, causing it to circulate. This allows the sediment detector to detect sediment in the flowing water, ensuring that the sediment content detected by the detector is within the flowing water. This prevents sediment deposition caused by stagnant water in the flow chamber, resulting in more accurate sediment detection results in the flowing water. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] like Figures 1-5 The sediment measurement device shown includes a flow tank 10, a water pump, a sediment detection component, and a water flow propulsion device 14. The flow tank 10 is provided with a flow cavity 12, an inlet 121, an outlet 123, an inlet pipe, and an outlet pipe. One end of the inlet pipe can be directly connected to a river or lake or other site where water and soil monitoring is required. The length of the inlet pipe can be set according to the distance between the flow tank 10 and the measurement site.

[0033] The aforementioned inlet 121 is connected to one end of the flow chamber 12, and the outlet 123 is connected to the other end of the flow chamber 12. The inlet pipe is connected to the inlet 121, and the outlet pipe is connected to the outlet 123, so that the inlet pipe can guide the water flow into the flow chamber 12. A water pump can be installed in the flow pool 10, and the inlet end of the water pump can be connected to the inlet 121, so that it can provide suction force to guide the water flow through the inlet pipe to the inlet 121 and into the flow chamber 12 of the flow pool 10.

[0034] The aforementioned sediment detection assembly includes a sediment detector 20 and a detection bracket 13. The bottom end of the detection bracket 13 is connected to the bottom wall of the flow chamber 12, and a support plate 132 is provided at the top end of the detection bracket 13. The sediment detector 20 is installed on the support plate 132 and is used to detect sediment in the water flow within the flow chamber 12. A water flow propeller 14 is used to agitate the water flow within the flow chamber 12.

[0035] Based on the above structure, when using the sediment measuring device of this utility model, the water pump is started. The water pump starts and guides the water flow through the inlet pipe to the inlet 121 and into the flow chamber 12 of the flow pool 10. During the process of extracting water, the outlet pipe or outlet 123 can be kept closed.

[0036] When the water flow in the flow chamber 12 reaches a certain measurement height, the water pump is turned off to start detecting the sediment content in the water flow. At this time, the water flow propeller 14 is activated, which agitates the water flow in the flow chamber 12. The water flow can circulate in the flow chamber 12 under the action of the water flow propeller 14, so that the sediment detector 20 can detect the sediment content in the flowing water. This ensures that the sediment content detected by the sediment detector 20 in the flow chamber 12 is the content in the flowing water, preventing sediment deposition due to the still water flow in the flow pool 10. Therefore, the sediment detection results in the flowing water are more accurate.

[0037] In addition, after the sediment measurement is completed in the flow tank 10, the outlet 123 is opened. At this time, the water in the flow chamber 12 can be discharged through the outlet 123 to the outlet pipe.

[0038] It should be noted that the sediment detector 20 in this embodiment can be a laser particle analyzer in the prior art for sediment particle measurement. Its sediment particle measurement structure and working principle are not the technical content to be protected in this application, and will not be described in detail here.

[0039] Of course, in addition to the method of installing the water pump in the flow-through pool 10 as in this embodiment, the water pump can also provide water flow extraction force at the inlet 121 of the flow-through pool 10. In other related embodiments, the water pump can also be installed on a river, with the pump inlet connected to the extraction pipe and the outlet connected to the inlet pipe. In this way, when the pump starts, it can guide river water or lake water into the inlet pipe and into the flow-through chamber 12 through the inlet 121.

[0040] Furthermore, two water flow propellers 14 are provided, which are located at both ends of the flow cavity 12 along its length and staggered along its width. This allows the water flow to be agitated at both ends of the flow cavity 12 along its length, ensuring that the water flow in the flow cavity 12 is fully agitated and reducing the possibility of incorrect sediment measurement due to uneven agitation in certain areas.

[0041] Specifically, the water flow propulsion device 14 includes a propulsion motor and a rotating component. The rotating component is equipped with helical blades, and the propulsion motor drives the rotating component to rotate. When agitating the water flow in the flow cavity 12, the rotating component can be driven to rotate by the rotation of the shaft of the propulsion motor, and the helical blades on the rotating component can agitate the water flow in the flow cavity 12.

[0042] Of course, the rotating parts can be made to rotate at a certain speed by controlling the speed of the propulsion motor, thereby making the water flow speed in the flow cavity 12 controllable.

[0043] It should also be noted that the speed of the propulsion motor can be set by the controller. The control principle is existing technology and is not part of the technical content to be protected in this application, so it will not be described in detail here.

[0044] Furthermore, the bottom wall of the flow cavity 12 includes a first bottom wall 124 and a second bottom wall 125. The first bottom wall 124 and the second bottom wall 125 are offset in the height direction, and the first bottom wall 124 is higher than the second bottom wall 125. The first bottom wall 124 surrounds the periphery of the second bottom wall 125, and the first bottom wall 124 and the second bottom wall 125 are connected by an inclined surface. The outlet 123 is provided on the second bottom wall 125. In this way, the bottom of the flow cavity is provided with an inclined first bottom wall 124, which guides the water flow to the lower second bottom wall 125 and concentrates it at the outlet provided on the second bottom wall 125, so that water and sediment can be completely discharged from the outlet end when draining.

[0045] Furthermore, the top side wall of the flow pool 10 is provided with an overflow outlet 122 and an overflow pipe. The overflow outlet 122 is connected to the top of the flow chamber 12. When the water pump continuously pumps, the water in the river flows into the flow pool 10 from the inlet. When the water level in the flow chamber 12 of the flow pool 10 is high enough, it will be higher than the overflow outlet 122 on the top side wall of the flow pool 10. The water that exceeds the water level can enter the overflow outlet 122 and be guided out through the overflow pipe. This keeps the water in the flow pool 10 flowing and also prevents the water level from being too high.

[0046] Furthermore, the top of the flow cell 10 is covered with a transparent plate 11, which is detachably sealed to the top of the flow cavity 12. In this way, when sediment detection is performed in the flow cell 10, the transparent plate 11 covers the top of the flow cavity 12, so that the flow cavity 12 is kept in a relatively closed state for detection, reducing the impact of external impurities entering the flow cavity 12 on the sediment detection results.

[0047] Limiting ribs 112 can also be provided around the bottom of the transparent plate 11. After the transparent plate 11 is sealed to the top of the flow pool 10, the limiting ribs 112 can abut against the inner wall of the top of the flow cavity 12, reducing the displacement of the transparent plate 11 after sealing. Furthermore, reinforcing ribs 113 are connected between two opposing limiting ribs 112, which can enhance the strength of the transparent plate 11.

[0048] Of course, by covering the bottom of the flow cavity 12 with a transparent plate 11, the operator can easily observe the situation inside the flow cavity 12.

[0049] Of course, multiple assembly holes 111 can also be provided on the transparent plate 11. During normal testing, the assembly holes 111 are sealed with a plug. However, when it is necessary to perform pH testing, oxygen content testing, etc. on the water flow in the flow chamber 12, different instruments need to be inserted into the flow chamber 12. Therefore, different testing instruments can be inserted and tested through the pre-reserved assembly holes 111 on the transparent plate 11.

[0050] Furthermore, the detection bracket 13 includes multiple support tubes 131 and multiple support plates 132. The multiple support tubes 131 are spaced apart along the length of the flow cell 10. Specifically, a connecting rod is connected between two opposing support tubes 131 in the width direction of the flow cavity 12. Thus, the bottom end of the detection bracket 13 forms a base structure with multiple support tubes 131 and connecting rods, resulting in a stable base structure. The multiple support plates 132 are installed one-to-one at the top of the multiple support tubes 131. The sediment detector 20 can be supported by the multiple support plates 132, and the housing of the sediment detector 20 can be connected to the support plates 132 by screws or pins, thus ensuring a stable assembly structure.

[0051] It should be noted that the support tube 131 and support plate 132 of the detection bracket 13 can be made of stainless steel, a material already available in the prior art.

[0052] Furthermore, both sides of the support plate 132 are provided with upwardly bent baffles (not shown in the figure). In this way, the baffles can block the sides of the sediment detector 20 and position the sides of the sediment detector 20, thereby reducing the displacement of the sediment detector 20 during the detection process.

[0053] Furthermore, the inlet pipe is equipped with a first solenoid valve, and the outlet pipe is equipped with a second solenoid valve. This allows the inlet pipe to be closed or opened by the first solenoid valve, thereby switching the inlet state within the flow chamber 12. Similarly, the outlet pipe can be closed or opened by the second solenoid valve, allowing the outlet state of the flow pool 10 to be switched by the opening or closing of the second solenoid valve.

[0054] Furthermore, a plurality of mounting blocks 15 are provided on the side wall of the flow pool 10, and the plurality of mounting blocks 15 are distributed at intervals in the height direction of the flow pool 10; mounting slots are provided on the mounting blocks 15.

[0055] After the water pump continuously guides the water flow into the flow chamber 12, a water level gauge can be installed in the flow pool 10 to facilitate water level detection. For easy assembly, the water level gauge can be installed in the mounting slot of the mounting block 15, allowing for convenient positioning and assembly, and facilitating easy disassembly and reassembly.

[0056] Since mounting blocks 15 are installed at different positions along the height of the flow pool 10, water level gauges can be installed in the mounting slots of mounting blocks 15 at different heights according to the water level measurement requirements. Alternatively, one water level gauge can be installed in the high-position mounting block 15, and another water level gauge can be installed in the low-position mounting block 15, thus enabling the detection of both high and low water levels.

[0057] Of course, based on the structure with different mounting blocks 15, the water jet propeller 14 can also be installed by connecting bolts or pins in the mounting groove of one of the mounting blocks 15 to assemble a mounting plate, and the water jet propeller 14 can be installed with the mounting plate as the assembly base.

[0058] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
