Description
Technical Field

[0002] The Yellow River sediment monitoring device is a device for monitoring the proportion of sediment in the Yellow River under different conditions. Due to the different precipitation in the four seasons, the amount of water in the Yellow River is different, so the ratio of sediment to water inside is also different. In order to control the internal sediment content according to the situation, it is necessary to monitor different areas or times. During the monitoring, the sediment and water need to be separated or stratified.
[0003] The patent application publication number is CN206945491U, which discloses a Yellow River sediment content measurement system. This device has a sealed box installed on the water intake funnel, and a turntable is provided at one end of the sealed box. The turntable is provided with a movable plate. The water flow can drive the turntable to rotate through the movable plate. The turntable drives the rotating rod to rotate through the transmission device and the gear set in the sealed box, and the rotating rod drives the rotating plate to rotate. The limiting device on the rotating plate cooperates with the empty groove to limit the pipeline, so that the rotating plate rotates while driving the pipeline to make a circular motion, causing the pipeline to vibrate, so that sand and dust will not accumulate in the pipeline, and the pipeline is prevented from being blocked.
[0004] However, the conventional device still has the following problems when used:
[0005] Since the above-mentioned process of detecting the sediment content of the Yellow River is to prevent pipe blockage, it is necessary to separate the water of the Yellow River from the sediment when detecting the sediment content of the Yellow River, so as to estimate the sediment content by the weight of the sediment. However, the existing device for separating water and sediment directly filters the water, and the sediment is likely to stick to the inside of the device during the filtration process, thereby affecting the measurement result.

At the same time, after the filter 4 is cleaned by the scraper 1 51, the patency of the filter 4 can be maintained, and the resistance of water flow through the filter 4 can be reduced, thereby accelerating the filtration speed and improving the efficiency of sediment treatment.
[0038] Embodiment 3: On the basis of embodiment 2, the outer wall of the main shaft 31 is rotatably connected to the middle position of the top of the detection box 1, and the outer wall of the main shaft 31 is located above the inside of the detection box 1 and is provided with a slide groove 45. The outer wall of the main shaft 31 is slidably connected with a connecting sleeve 46, and the inner wall of the connecting sleeve 46 is fixedly connected with a slide rod 47. The outer walls of the two slide rods 47 are slidably connected to the inside of the slide groove 45, and the outer wall of the connecting sleeve 46 is fixedly connected with a connecting plate 2 41, and the outer walls of multiple connecting plates 2 41 are fixedly connected with a filter screen 4, and the outer wall of the filter screen 4 is rotatably connected to the inside of the detection box 1, and the bottoms of multiple connecting plates 2 41 are fixedly connected with U-shaped grooves 42, and the rotation of multiple U-shaped grooves 42 is connected to a rotating shaft, and the outer wall of the bottom of the rotating shaft is fixedly connected with multiple mounting rods 43, and the bottom of the mounting rod 43 is fixedly connected with a knocking ball 44, and the outer wall of the knocking ball 44 is in active contact with the outer wall of the frame 5.
[0039] By generating a collision between the knocking ball 44 and the frame 5, and then utilizing the collision force between the knocking ball 44 and the frame 5, the frame 5 can be vibrated, and when continuing to move through the U-shaped groove 42, the mounting rod 43 can drive the rotating shaft to rotate ninety degrees inside the U-shaped groove 42, so that the mounting rod 43 drives the knocking ball 44 to pass through the frame 5, and then the vibration force generated by the frame 5 can loosen the mud and sand particles attached to the surface of the filter screen 4, so that the scraper 51 can scrape off the mud and sand more effectively. At the same time, the mud and sand on the surface of the frame 5 can also be shaken off, further improving the detection effect of the cement sand of the Yellow River.
[0040] Embodiment 4, on the basis of embodiment 3, the bottom of the filter screen 4 is internally rotatably connected with a circular shell 7, the internal rotatable connection of the circular shell 7 is provided with a plurality of movable plates 2 71, the bottom of the scraper plate 2 52 is in movably contact with the top of the circular shell 7, a circular hole with outer walls on both sides connected is provided in the middle of the circular shell 7, the outer wall of the top of the circular shell 7 is located on the outside of the circular hole and is fixedly connected with a limiting ring 72, the outer walls of the opposite sides of the plurality of movable plates 2 71 are fixedly connected with a mounting groove 84, the outer wall of the mounting groove 84 is rotatably connected with the internal part of the circular shell 7, the lower part of the outer wall of the main shaft 31 is slidably connected with a mounting ring 8, the outer wall of the bottom of the main shaft 31 is fixedly connected with a hexagonal block 83, the inner wall of the mounting ring 8 is fixedly connected with a socket 82, a strip hole with outer walls on both sides connected is provided below the outer wall of the main shaft 31, the outer wall of the socket 82 is slidably connected with the inner part of the strip hole, the inner part of the mounting ring 8 is rotatably connected with the outer wall of the limiting ring 72, and the outer wall of the hexagonal block 83 is movably plugged into the inner part of the mounting groove 84.
[0041] By entering the interior of the circular shell 7 through the movable plate 2 71, the notch on the circular shell 7 is exposed, and the mud and sand inside the filter screen 4 can enter the interior of the collecting tank 6 through the notch on the circular shell 7 for collection. Through the cooperation of the circular shell 7 and the movable plate 2 71, when the filter screen 4 is working, it is possible to prevent water from flowing downward through the bottom of the filter screen 4 into the interior of the collecting tank 6, thereby affecting the purity of the mud and sand. Accordingly, it is ensured that the collected mud and sand are purer, which is beneficial to the subsequent detection effect of the mud and sand.
[0042] Embodiment 5, based on embodiment 4, a plug hole 82 is opened on the outer wall of the bottom of the frame 5, and a plug rod 81 is movably inserted into the plug hole 82, and the outer wall of the bottom of the plug rod 81 is fixedly connected to the protrusion of the outer wall of the mounting ring 8.
[0043] By inserting the rod 81 inside the socket 82, when the main shaft 31 drives the mounting ring 8 to rotate, the rod 81 can drive the socket 82 to rotate, so that the frame 5 moves accordingly, and then through the rotation of the frame 5, the scraper 2 52 can be driven to scrape off the mud and sand on the surface of the circular shell 7, avoiding the mud and sand remaining on the top of the circular shell 7. The measurement of the water sediment of the Yellow River is correspondingly increased, and the accuracy of the mud and sand detection is correspondingly increased.
[0044] The working principle and use process of the present invention are as follows: when in use, first, water with silt taken out from the Yellow River is poured into the interior of the detection box 1 from the water inlet trough, and the water carrying silt can be poured into the interior of the filter screen 4 through the water inlet trough above the filter screen 4. At this time, the motor 3 is started, and then the rotation of the motor 3 can drive the sliding rod 47 to drive the connecting sleeve 46 to rotate accordingly, and then the rotation of the connecting sleeve 46 can drive the connecting plate 2 41 to drive the filter screen 4 to rotate accordingly, and then the centrifugal force generated by the rotation of the filter screen 4 can be used to separate the internal Yellow River water, so that the water is thrown out of the interior of the filter screen 4 through the filter holes on the filter screen 4, and then enters the bottom of the detection box 1, and then through the setting of the filter screen 4, the silt can be connected to the interior of the filter screen 4, thereby completing the separation of the Yellow River water and water. The centrifugal separation method is not strictly limited by the silt particle size, can process silt of different particle sizes, and has a wider range of application.
[0045] By rotatably connecting the outer ring 54 and the inner ring 55, when the main shaft 31 drives the inner ring 55 to rotate on the outer ring 54, the cylinder 56 can rotate accordingly, thereby maintaining the stability of the frame 5. Then, by setting the cylinder 56, the friction between the outer ring 54 and the inner ring 55 can be reduced, thereby increasing the service life of the outer ring 54 and the inner ring 55 and reducing the maintenance or replacement of the outer ring 54 and the inner ring 55.
[0046] Furthermore, since the frame 5 is rotatably connected to the main shaft 31, when the connecting plate 2 41 drives the filter screen 4 to rotate, the frame 5 can drive the scraper 1 51 to clean the inside of the filter screen 4, thereby preventing mud and sand from sticking to the inner wall of the filter screen 4, and correspondingly preventing excessive accumulation of mud and sand on the filter screen 4 to affect the subsequent collection and detection of water samples, thereby ensuring that the water sample tested each time is as close as possible to the actual mud and sand content in the Yellow River water. At the same time, after the filter screen 4 is cleaned by the scraper 1 51, the patency of the filter screen 4 can be maintained, and the resistance of water flow through the filter screen 4 can be reduced, thereby accelerating the filtration speed and improving the efficiency of mud and sand treatment.
[0047] When the connecting plate 41 is rotated again, the U-shaped groove 42 can drive the installation rod 43 to move. When the U-shaped groove 42 drives the installation rod 43 to move to the position of the frame 5, a collision can be generated between the knocking ball 44 and the frame 5. The force generated by the collision between the knocking ball 44 and the frame 5 can be used to make the frame 5 vibrate. When the U-shaped groove 42 continues to move, the installation rod 43 can drive the rotating shaft to rotate ninety degrees inside the U-shaped groove 42, so that the installation rod 43 drives the knocking ball 44 to pass through the frame 5. The vibration force generated by the frame 5 can loosen the mud and sand particles attached to the surface of the filter screen 4, so that the scraper 51 can scrape off the mud and sand more effectively. At the same time, the mud and sand on the surface of the frame 5 can also be shaken off, further improving the detection result of the cement sand of the Yellow River.
[0048] The stirring rod 53 provided on the frame 5 can distribute the fluid more evenly when it enters the filter screen 4, thereby reducing the formation of local eddies or dead zones, thereby helping to improve the separation efficiency.
[0049] When the separation of mud and water is completed, the cylinder 2 can be started, and then through the movement of the cylinder 2, the connecting plate 21 can drive the motor 3 and the main shaft 31 to move downward, and then through the downward movement of the main shaft 31, the slide groove 45 can slide on the slide rod 47, so that the main shaft 31 drives the frame 5 and the hexagonal block 83 to move downward at the same time, so that the socket 82 on the frame 5 is inserted into the outer wall of the plug rod 81. When the socket 82 is halfway inserted into the outer wall of the plug rod 81, the hexagonal block 83 begins to enter the interior of the installation groove 84. When the hexagonal block 83 completely enters the interior of the installation groove 84, the motor 3 can be started again, and then through the movement of the motor 3, the By moving, the main shaft 31 can drive the installation groove 84 to move, so that the installation groove 84 drives the movable plate 2 71 to rotate inside the circular shell 7, and the movable plate 2 71 can enter the interior of the circular shell 7, thereby exposing the notch on the circular shell 7, and the mud and sand inside the filter screen 4 can enter the interior of the collecting tank 6 through the notch on the circular shell 7 for collection. Through the cooperation between the circular shell 7 and the movable plate 2 71, when the filter screen 4 is working, it can be prevented that the water flows downward through the bottom of the filter screen 4 and enters the interior of the collecting tank 6, thereby affecting the purity of the mud and sand. Correspondingly, it is ensured that the collected mud and sand are purer, which is beneficial to the subsequent detection effect of the mud and sand.
[0050] It should be noted that: when the movable plate 2 71 enters the interior of the circular shell 7, the main shaft 31 can move upward in the movable hexagonal block 83 under the action of the cylinder 2. When the hexagonal block 83 is completely moved out of the installation groove 84, a part of the insertion rod 81 is still inside the socket 82.
[0051] It should be noted that: by setting the movable plate 1 61 , the collecting tank 6 can be pulled out from the inside of the detection box 1 .
[0052] When the hexagonal block 83 is moved out of the installation groove 84, the motor 3 can be started to rotate. At this time, the rod 81 is inserted into the socket 82, so that when the main shaft 31 drives the installation ring 8 to rotate, the rod 81 drives the socket 82 to rotate, so that the frame 5 moves accordingly. Then, through the rotation of the frame 5, the scraper 2 52 can be driven to scrape off the mud and sand on the surface of the circular shell 7, avoiding the mud and sand remaining on the top of the circular shell 7. The measurement of the water sediment of the Yellow River is correspondingly increased, and the accuracy of the mud and sand detection is correspondingly increased.
[0053] By cooperating with the mounting ring 8, the insertion hole 82 and the strip hole, when the main shaft 31 moves upward or downward, the mounting ring 8 is always on the outer wall of the limiting ring 72, thereby preventing mud and sand from entering the interior of the mounting groove 84. The mud and sand will fill the mounting groove 84 and affect the insertion of the hexagonal block 83, thereby correspondingly increasing the coordination effect between the hexagonal block 83 and the mounting groove 84.
[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
