Description

Technical Field

[0001] The invention relates to the technical field of soil and water loss detection, and in particular to a portable automatic soil and water loss monitoring device. Background Art

[0002] The soil erosion monitoring device of the slope runoff observation field is mainly composed of a runoff collection device, a runoff measurement and positioning device, a runoff sediment mixing device and other parts. The most important of these are the runoff measurement and positioning device and the runoff sediment mixing device, which can effectively monitor the slope runoff water and soil data to ensure that the monitoring results obtained have a high degree of accuracy. Therefore, the application of the data obtained from the soil erosion monitoring of the slope runoff observation field in the city can effectively save water resources in the city, enhance people's awareness of water conservation, and increase the existing water resources output. When carrying out water conservation work, the city can use this data as a basis for operation, and formulate a scientific and reasonable water conservation measure in combination with the local climate environment, geographical location, etc. Only in this way can the occurrence of soil erosion in the city be reduced, the waste of water resources can be reduced, and the natural ecological environment can be protected.

[0003] For soil and water loss monitoring, the commonly used methods at home and abroad include near-infrared method, transmission method, emission method, etc. The above methods require the samples to be tested in a turbid state after repeated stirring. For example, the projection method uses the law of reflection of light. Part of the light irradiated on the water flow is transmitted through the sand-containing water flow, part is absorbed by the water flow and sediment, and part is reflected by the water flow and sediment; the light is projected into the water flow, and the reflected light is captured by the infrared sensor to detect the sediment content. In the laboratory, since the collected samples and sediment will quickly stratify in the water, they need to be placed in a mixing container for mixing and stirring. However, the stirring direction of the stirring equipment is relatively single, and vortices are easily generated during mixing and stirring, resulting in regional distribution of sediment, making it difficult to achieve rapid and uniform mixing. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a portable automatic soil and water loss monitoring device. The portable design allows timely use of outdoor sampling. At the same time, in order to avoid detection errors caused by stratification of collected samples, a rotatable sampling cabin is provided to allow the collected samples to be quickly rotated or oscillated to achieve mixing and then flow through a detection instrument to achieve accurate detection.

[0005] In order to solve the above technical problems, the present invention solves the problems of rapid sedimentation in samples, laborious manual shaking, and vortexes easily occurring when shaking with equipment, which affects the detection accuracy through the following technical solutions.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A portable automatic monitoring device for soil and water loss comprises a sampling tube for collecting sediment, a workbench for detecting sediment, and a sampling cabin for storing sediment samples. The sampling cabin is connected to the workbench through a first connecting tube. One end of the sampling tube is connected to the sediment detection workbench for sediment to flow into the sampling cabin. The horizontal ends of the sediment detection workbench are symmetrically connected to a driving mechanism and a detection component that support it and are rotatably connected to it. An upper bracket and a lower bracket are respectively installed on the upper and lower sides of the workbench. The ends of the upper bracket and the lower bracket are respectively inserted into the driving mechanism and the detection component and then connected.

[0011] Preferably, a sleeve covering the limiting groove is rotatably connected to the outer side of the support member, a second connecting pipe is connected and fixed to one side of the sleeve, a side edge of the second connecting pipe is connected to the driving mechanism through a support, and the second connecting pipe is connected to the sampling tube.

[0012] Preferably, the driving mechanism includes a motor box rotatably connected to one of the supporting members, and a driver installed inside the motor box, and the driver output shaft is fixedly connected to the supporting member to drive the workbench, the first connecting tube and the sampling chamber to rotate.

[0013] Preferably, the detection assembly includes a collection box rotatably connected to one of the supporting members, an infrared sensor installed on the data collector and electrically connected to the data collector, and a sealing plug. A sealing plug is clamped on the collection box and penetrates into the interior of the installation groove. The infrared sensor is installed at the end of the sealing plug and penetrates into the interior of the detection box.

[0014] Preferably, the upper bracket includes a top plate, and limiting rods are symmetrically provided on both sides of the bottom of the top plate. The limiting rods respectively penetrate into the motor box and the collection box from above and slideably cooperate with them.

[0015] Preferably, the lower bracket includes a base, and guide tubes are symmetrically provided on both sides of the bottom of the base. The guide tubes respectively penetrate into the motor box and the collection box from below and slideably cooperate with them.

[0016] Preferably, locking pieces are installed on the upper and lower end surfaces of the motor box and the collection box, and the limit rod and the guide tube pass through the locking pieces and enter the motor box and the collection box respectively, and the limit rod can penetrate into the guide tube and slide with it.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, two sampling chambers are symmetrically connected around the upper and lower parts of a workbench. After a sampling tube is connected to the workbench from the side, the sample is stored in the sampling chamber.

The workbench and the sampling chamber can be rotated, and the sample is fully mixed and then flows through the workbench, which can improve the accuracy of the detection. At the same time, the sample can be cleaned by rotation after being discharged.

[0019] The present invention can quickly achieve sample mixing by controlling the rotation or oscillation of the sampling chamber, and can avoid the eddy current caused by the stirring mechanism when stirring and mixing, which may cause the regional distribution of sediment and the image detection effect. The present invention can eliminate the need for a stirring mechanism, and reduce the cost and complexity of maintenance and installation.

[0020] The sampling cabin of the present invention does not need to adopt a cleaning structure for cleaning. When facing adsorption dirt, steel balls are added and then oscillated to achieve efficient and clean cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example:

[0037] A portable automatic monitoring device for soil and water loss comprises a sampling tube 100 for collecting sediment, a workbench 200 for detecting sediment, and a sampling cabin 300 for storing sediment samples. The sampling cabin 300 is connected to the workbench 200 through a first connecting tube 400. One end of the sampling tube 100 is connected to the sediment detection workbench 200 for sediment to flow into the sampling cabin 300. A driving mechanism 500 and a detection assembly 600 that support and are rotatably connected to the sediment detection workbench 200 are symmetrically connected at both horizontal ends. An upper bracket 700 and a lower bracket 800 are respectively installed on the upper and lower sides of the workbench 200. The ends of the upper bracket 700 and the lower bracket 800 are respectively inserted into the driving mechanism 500 and the detection assembly 600 and then connected.

[0038] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0039] See also Figure 1-3 The present application discloses a portable automatic monitoring device for soil and water loss, comprising a sampling tube 100, a workbench 200, a sampling cabin 300, a first connecting pipe 400, a driving mechanism 500, and a detection assembly 600. The middle of the workbench 200 is a hollow structure. One end of the sampling tube 100 for collecting sediment is installed on the workbench 200 and connected to the middle thereof. The sampling cabin 300 is connected to the middle of the workbench 200 through the first connecting pipe 400. Sediment will pass through the workbench 200 and enter the interior of the sampling cabin 300. The detection assembly 600 installed on the side of the workbench 200 will detect the sediment flowing through the workbench 200.

[0040] Among them, the present application designs two sampling chambers 300 to be symmetrically arranged around the workbench 200, and are connected to the workbench 200 through the first connecting pipe 400. In order to prevent the collected sediment from settling quickly and the water layer from affecting the detection effect, a driving mechanism 500 is installed on the side of the workbench 200 to control the rotation of the workbench 200 and the two sampling chambers 300 to rotate around the workbench 200. After the sediment inside the lower sampling chamber 300 is stirred and turbid during the rotation process, the sediment is at a high position and flows through the middle of the workbench 200 into the sampling chamber 300 in the west. The detection component 600 detects the sediment, which can improve the detection effect. And the sampling chamber 300 can also be cleaned by rotating.

[0041] See also Figure 4-6In the present application, the workbench 200 is composed of a rectangular hollow detection box 201 and a columnar support member 202. The two support members 202 are symmetrically fixed at the two ends of the detection box 201. One support member 202 faces the detection component 600 and is rotatably connected. A mounting groove 205 is provided in the support member 202. The other support member 202 faces the driving mechanism 500. A limiting groove 206 is provided in the support member 202. Through holes 203 are provided at both the upper and lower ends and the left and right ends of the detection box 201. The through holes 203 at the upper and lower ends are connected to the first connecting tube 400, and the through holes 203 on the left and right sides are respectively connected to the mounting groove 205 and the limiting groove 206.

[0042] The installation groove 205 is a horizontally penetrating structure, and part of the detection assembly 600 is inserted into the detection box 201 through the installation groove 205. The limiting groove 206 is a 90° curved structure, one end of the limiting groove 206 is connected to the through hole 203, and the other end is connected to the outside through the side of the support 202. A sleeve 207 is sleeved on the outside of the support 202 to seal the limiting groove 206. A hole is opened at the top of the sleeve 207 and a second connecting pipe 208 is installed. The second connecting pipe 208 is connected to the limiting groove 206, and the sampling tube 100 is connected to the second connecting pipe 208. The mud and sand will enter the second connecting pipe 208 from the sampling tube 100, and then enter the limiting groove 206, flow into the middle of the detection box 201 through the limiting groove 206, and then flow into the sampling cabin 300 through the through hole 203 at the bottom of the detection box 201. In addition, the second connecting tube 208 is connected and fixed to the driving mechanism 500 via a support. When the driving mechanism 500 drives the supporting member 202 to rotate, the sleeve 207 and the second connecting tube 208 remain stationary to avoid winding around the sampling tube 100.

[0043] It should be noted that the sampling tube 100 is a soft pipe, which is convenient for adjusting the angle to collect sediment; the first connecting tube 400 and the second connecting tube 208 are both hard metal pipes.

[0044] See also Figure 5 , 7 In the present application, the driving mechanism 500 includes a motor box 501, a driver 502, etc. The driver 502, a battery, etc. are installed inside the motor box 501. The motor box 501 is arranged on the side of the workbench 200 and is rotatably connected to the support 202. The power output shaft of the driver 502 is fixedly connected to the support 202. Driven by the driver 502, the workbench 200 rotates, and the first connecting tube 400 and the sampling chamber 300 rotate around the workbench 200.

[0045] See also Figure 5 , 8In the present application, the detection assembly 600 includes a collection box 601, a data collector 602, and an infrared sensor 603. The collection box 601 is installed on one side of the workbench 200 and is rotatably connected thereto. The data collector 602 is installed on the collection box 601 and is electrically connected to the infrared sensor 603. A sealing plug 604 inserted into the installation slot 205 is installed on the collection box 601. The infrared sensor 603 is installed at the end of the sealing plug 604. The infrared sensor 603 is distributed inside the detection box 201. After the sediment passes through the detection box 201, it is used on the sediment side. The infrared sensor 603 uses an emission method to detect the sand content of the flowing mud and sand.

[0046] In addition, the first connecting tube 400 and the sampling chamber 300 in the present application are easy to disassemble and can be removed after sampling or testing.

[0047] In some embodiments, a valve is installed at the bottom of the sampling chamber 300 to discharge the collected sample.

[0048] See also Fig. 9 In the present application, an upper bracket 700 and a lower bracket 800 are respectively arranged on the upper and lower sides of the workbench 200. The upper bracket 700 is composed of a top plate 701 and a limiting rod 702. The limiting rod 702 is symmetrically fixed on both sides of the bottom surface of the top plate 701, so that the upper bracket 700 has a U-shaped structure; the lower bracket 800 is composed of a base 801 and a guide tube 802. The guide tube 802 is symmetrically arranged on both sides of the top of the base 801, so that the lower bracket 800 has a U-shaped structure.

[0049] The upper bracket 700 and the lower bracket 800 are symmetrically arranged, and penetrate into the motor box 501 and the collection box 601 from the upper and lower sides respectively and interact with them. The limiting rod 702 and the guide tube 802 on the same side are in the vertical direction, and the limiting rod 702 can penetrate into the guide tube 802. The upper and lower end surfaces of the motor box 501 and the collection box 601 are both installed with locking parts, and the limiting rod 702 and the guide tube 802 pass through the locking parts and enter the motor box 501 and the collection box 601 respectively.

[0050] When the monitoring device is deployed, the upper bracket 700 and the lower bracket 800 are stretched to the upper and lower sides respectively, and the base 801 is in contact with the ground. The workbench 200 is in the middle position, and the first connecting pipe 400 and the sampling chamber 300 are installed on the upper and lower sides respectively, and the sampling tube 100 is connected to the top of the workbench 200. The collected sediment flows into the sampling chamber 300 below through the workbench 200.

[0051] During the sampling process, the infrared sensor 603 will detect the sand content in the sample. In order to ensure the accuracy of the detection, the driver 502 drives the workbench 200 and the two sampling chambers 300 to rotate, so that the samples can be mixed and the sediment can be evenly distributed. The samples are then allowed to flow from a high place into the empty sampling chamber 300 below, and the uniform samples flow through the infrared sensor 603 again for accurate detection.

[0052] When the monitoring device is stored, the first connecting tube 400 and the sampling chamber 300 are removed from the workbench 200 and stored separately, and the limiting rod 702 is inserted into the guide tube 802, so that the upper bracket 700 and the lower bracket 800 are moved closer to the workbench 200 and stored in the smallest state, and a handle is installed on the top plate 701 for easy carrying.

[0053] In addition, the optional sampling chamber 300 designed in the present application can be tilted by rotating, and can achieve efficient and sufficient flushing when there is no tilting equipment on the surface. When facing difficult-to-clean dirt, a small amount of balls can be added to the inside of the sampling chamber 300 to accelerate the cleaning process during the rotation. It should also be noted that the infrared sensor 603 needs to be removed before adding the balls to avoid damage to it.

[0054] The present application adopts the method of rotating or oscillating the sampling chamber 300 to shake, which can avoid the problem of vortex generated by traditional stirring mechanism and uneven distribution of mud and sand, and eliminate the use of stirring equipment, reduce costs, and reduce the tediousness of maintenance.

[0055] It should be noted that the present application uses the reflection method for sediment detection, wherein the right side of the infrared sensor is connected to the detection box 201, allowing the sediment to pass through one side thereof. In some embodiments, the near infrared method or the transmission method can also be used for detection, and the detection instrument is passed into the detection box 201 to allow the sediment to pass through.

[0056] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
