Description

Technical Field

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

[0002] Among river hydrological monitoring data, sediment content is an important monitoring data. By analyzing river sediment content data, we can obtain important information about climate and environment, such as flood season, rainfall intensity, vegetation coverage and soil erosion.

[0003] When it is necessary to monitor the sediment content of a river, the existing technology generally involves first collecting water from the river, then filtering the sediment in the river in a laboratory, and then weighing the weight of the filtered sediment to obtain the sediment content in the river. However, this process is relatively complicated. At the same time, when it is necessary to detect the sediment content at different locations of the river, it is necessary to use a collection bottle to collect multiple samples for testing. When it is necessary to detect a deep location in the river, it is necessary to use other tools to put the collection bottle into the deep river, and then control the collection bottle to open to complete the collection of samples. This method is inefficient, and rivers located in or near areas rich in mineral resources usually contain a high concentration of metal particles in their sediment. When filtering the sediment in the river, the metal particles in the sediment will be mixed in the sediment, resulting in an increase in the mass of the sediment. At this time, the monitored sediment content will be higher than the actual sediment content, greatly reducing the accuracy and reliability of monitoring the sediment content in the river.

[0032] Specifically, after the silt is filtered, the silt and the metal particles mixed in the silt can be screened in the detection box 1 to prevent the metal particles in the silt from being mixed in the silt, resulting in an increase in the mass of the silt and affecting the detection of the sediment content in the river.

[0033] In the embodiment, the filter assembly 14 includes a shell 141 to which the side walls at both ends of the detection box 1 are fixedly connected, and the inner walls at both ends of the two shells 141 are rotatably connected with collection rods 142, and the rod wall of one of the collection rods 142 is wound with a filter screen 143, and the side walls of the detection box 1 and the two shells 141 are provided with openings for the filter screen 143 to move, and the other end of the filter screen 143 passes through the shell 141 and the side wall of the detection box 1 and is fixedly connected to the rod wall of the other collection rod 142, and one end of the side walls of the two shells 141 are fixedly connected to the second motor 144, and the output end of the second motor 144 passes through the side wall of the shell 141 and is fixedly connected to one end of the corresponding collection rod 142.

[0034] Specifically, the sediment in the river water can be filtered, and at the same time, the sediment remaining on the surface of the filter screen 143 can be accumulated on one side of the detection box 1 by controlling the second motor 144 to start, so as to facilitate the subsequent collection and detection of the sediment.

[0035] In the embodiment, the collecting assembly 12 includes two electric slide rails 121 fixedly connected to the inner walls of the first grooves 11, and the side walls of one end of the electric slide rails 121 are slidably connected to the slide plates 122, and the side walls of the slide plates 122 are fixedly connected to the second electric telescopic rod 123, and the telescopic end of the second electric telescopic rod 123 is fixedly connected to the L-shaped plate 124, and the top inner wall of the L-shaped plate 124 is fixedly connected to the third electric telescopic rod 125, and the telescopic end of the third electric telescopic rod 125 is fixedly connected to the scraper 126.

[0036] Specifically, the silt and metal particles can be collected separately to facilitate subsequent processing, which greatly improves the accuracy and reliability of the device in monitoring the sediment content of rivers.

[0037] In the embodiment, the detection assembly 10 includes two shells 101 symmetrically fixedly connected to the side walls of one end of the detection box 1, wherein a pressure sensor 102 is fixedly connected to the inner wall of the bottom end of one of the shells 101, and a support spring 103 is fixedly connected to the detection end of the pressure sensor 102, and a drying plate 104 is fixedly connected to one end of the support spring 103, and the side walls of the drying plate 104 are in conflict with the inner wall of the corresponding shell 101, and a fourth electric telescopic rod 105 is fixedly connected to the inner wall of one end of the two shells 101, and the telescopic ends of the fourth electric telescopic rod 105 are fixedly connected to the block 106, and the side walls of the shell 101 at the adjacent end of the detection box 1 are provided with an opening for the block 106 to move.

[0038] Specifically, the silt accumulated on the surface of the filter screen 143 is pushed into the casing 101 by the scraper 126 and finally falls on the surface of the heating plate. At this time, the heating plate is started to evaporate the water in the silt. After the water in the silt is completely evaporated, the pressure value detected by the pressure sensor 102 is the mass of the silt. The mass of the silt is then calculated with the total mass of water to detect the sand content of the river silt.

[0039] In the embodiment, a support column 15 is fixed to the top inner wall of the detection box 1, one end of the support column 15 is fixedly connected to a limit plate 16, two fifth electric telescopic rods 17 are symmetrically fixedly connected to the top inner wall of the detection box 1, and the telescopic ends of the two fifth electric telescopic rods 17 are fixedly connected to the same cleaning frame 18, the inner wall of the cleaning frame 18 conflicts with the side wall of the limit plate 16, and the outer wall of the cleaning frame 18 conflicts with the inner wall of the detection box 1.

[0040] Specifically, before the subsequent detection of the sand content of the river sediment is needed, the fifth electric telescopic rod 17 is controlled to start, driving the cleaning frame 18 to move downward, so that the sediment adhered to the inner wall of the detection box 1 can be scraped downward, and the sediment falls on the surface of the filter screen 143, which is convenient for collecting the sediment and facilitating the subsequent detection of the sand content of the river sediment.

[0041] The operating principle of the present invention is now described as follows:

[0042] In the present invention, when it is necessary to monitor the sand content in the river sediment, the staff will first tie the rope to the hook 2, and then put the detection box 1 to the position where the sand content in the river sediment needs to be detected. At this time, the staff will release the rope and will not bring tension to the detection box 1. Under the action of gravity, the detection box 1 will continue to sink to the bottom of the river. After the detection box 1 sinks to the required position, multiple air pumps 133 are controlled to start, and the gas in the corresponding gas storage tank is transported to the air bag 135 through the connecting pipe 134, so that the detection box 1 generates buoyancy, and the gas transported by the air pump 133 to the air bag 135 can keep the detection box 1 in this position. Since the river has a large fluidity, it will cause an impact on the detection box 1, which is easy to cause the detection box 1 to tilt. At this time, the surroundings of the detection box 1 The water pressure detected by the water pressure sensor 131 arranged on the side wall is inconsistent. The position of the water pressure sensor 131 that detects a higher water pressure is the position where the water flow impacts the detection box 1. At this time, the detection box 1 is tilted, and the corresponding air pump 133 is controlled to start again, and continue to transport gas into the air bag 135, so that one side of the detection box 1 overcomes the impact of the water flow and swings in the direction of the water flow impact. When the water pressures detected by the four water pressure sensors 131 are roughly the same, the air pump 133 is controlled to be closed, thereby ensuring that the detection box 1 is vertical in the river, facilitating the subsequent separation of silt and metal particles in the silt, so that the device can accurately detect the sand content in the river silt. After ensuring that the detection box 1 can always remain in a vertical state, the first water pump 4 is controlled to The first solenoid valve 5 is opened, and the water in the river is transported to the inside of the detection box 1 through the water inlet pipe 3. In the process of water flowing into the inside of the detection box 1, multiple air pumps 133 are controlled to simultaneously supply air to the airbag 135 to ensure that the detection box 1 will not sink downward when collecting water. When the water in the detection box 1 reaches the lower surface of the limit plate 16, the water in the detection box 1 reaches the designed capacity position, and then the first water pump 4 and the first solenoid valve 5 are closed. At this time, the quality of the water collected in the detection box 1 can be calculated. Since the water inlet pipe 3 is located above the detection box 1, when the water inlet pipe 3 drains water into the detection box 1, the water will fall on the surface of the filter screen 143. At this time, the filter screen 143 will filter the sediment, and then the second water pump 7 and the second solenoid valve 8 are controlled to start. The filter 143 is moved to discharge the water in the detection box 1 into the river through the outlet pipe 6. In this process, the filter 143 will filter the silt in the water in the detection box 1 on the surface, and the water is discharged from the detection box 1. After the water is completely discharged, the silt in the water and the metal particles mixed therein will remain on the surface of the filter 143. Then, the first electric telescopic rod 91 is controlled to start, so that the mounting plate 92 contacts the lower surface of the filter 143, and then the multiple fans 94 are controlled to start, so that the wind passes through the filter 143 to blow the silt and the metal particles mixed in the silt upward. Since the silt contains a lot of water at this time, and the water absorption rate of the metal particles is lower than that of the silt, the mass of the metal particles is lighter than that of the silt, and the metal particles will be blown to the top of the inside of the detection box 1.The silt will be located below the metal particles, completing the stratification between the metal particles and the silt, and then the first motor 99 is controlled to start, driving the rotating rod 97 to rotate, so that the two baffles 98 move to the opposite end until the two baffles 98 touch each other. Since the two baffles 98 are located below the metal particles and block the wind blown by the fan 94, the metal particles will fall on the upper surface of the baffle 98. Then the fan 94 is controlled to be turned off, and the silt will fall on the surface of the filter screen 143 again. Then the two second motors 144 are controlled to start at the same time to drive the two collecting rods 142 to rotate, so that the filter screen 143 wrapped around the surface of one of the collecting rods 142 is wrapped around the outer wall of the other collecting rod 142. At this time, the silt on the surface of the filter screen 143 will accumulate on the detection box 1 The inner wall of one side is then controlled, and the second electric telescopic rod 123 in the direction of sediment accumulation is started to make the scraper 126 extend from the first groove 11, and then the third electric telescopic rod 125 is controlled to start to make the lower surface of the scraper 126 contact the upper surface of the filter screen 143, and then the fourth electric telescopic rod 105 on the side adjacent to the scraper 126 is controlled to shrink so that the block 106 does not block the opening here, and then the electric slide rail 121 in the direction of sediment accumulation is controlled to start to drive the slide plate 122 and the scraper 126 to move, and the sediment accumulated on the surface of the filter screen 143 is pushed into the casing 101 through the scraper 126, and finally falls on the surface of the heating plate. At this time, the heating plate is started to evaporate the water in the sediment. After the water in the sediment is completely evaporated, The pressure value detected by the pressure sensor 102 is the mass of the sediment, and then the obtained sediment mass and the total mass of water are calculated to detect the sediment content of the river sediment here, and then the first motor 99 is controlled to rotate in the opposite direction so that the baffle 98 does not block the metal particles. At this time, the metal particles will fall on the surface of the filter screen 143, and then the second motor 144 is controlled to rotate in the opposite direction. According to the above steps, the metal particles are accumulated on the other side of the inner wall of the detection box 1, and then the other second electric telescopic rod 123, the third electric telescopic rod 125, the fourth electric telescopic rod 105 and the electric slide rail 121 are controlled to start, so that another scraper 126 pushes the metal particles into another casing 101, thereby completing the collection of the metal particles, which can be used for the detection of metal particles that are not River water at the same depth and different positions can be quickly collected, and then the silt can be filtered in the river, avoiding the need to use a collection bottle to collect multiple samples for testing when the silt content at different positions of the river needs to be tested. The airbag 135 can accurately control the depth of the detection box 1 in the river, and at the same time ensure that the detection box 1 remains vertical in the river, which is convenient for subsequent silt filtering. After the silt is filtered, the silt and metal particles mixed in the silt can be screened in the detection box 1 to prevent the metal particles in the silt from being mixed in the silt, resulting in an increase in the mass of the silt and affecting the detection of the silt content in the river. The silt and metal particles can be collected separately for subsequent processing.The accuracy and reliability of the device in monitoring the sediment content of rivers have been greatly improved.
