Abstract
Description
Technical Field
[0001] The invention relates to the technical field of silt collectors, in particular to a river silt collector. Background Art
[0002] In the process of water environment monitoring and sediment pollution source tracing and treatment, in-situ sampling of riverbed silt is a key step in obtaining information on sediment pollution. Riverbed silt is typically composed of a long-term accumulation of fine-grained sediment, organic matter, biological debris, and pollutants. Its typical characteristics include high water content, loose structure, and susceptibility to disturbance. These characteristics place high demands on the structural design and operational precision of sampling tools. Accurate, efficient, and non-disturbance acquisition of silt samples at different depths and structural levels is a crucial foundation for water pollution assessment, heavy metal fate analysis, and analysis of the distribution characteristics of organic pollutants.
[0003] (1) Commonly used sediment sampling equipment includes manual column samplers, gravity sampling tubes, auger sampling devices, etc. These devices mostly use mechanical insertion or drilling to complete sediment extraction. The technical difficulties are mainly concentrated in the following aspects: (2) Soft mud with high water content is difficult to maintain structural integrity: conventional grab or shovel sampling processes can easily cause mud sample disturbance, morphological damage, or even loss, affecting the in-situ representativeness of the test data; (3) Vertical continuous profile sampling is difficult: single-section or fixed-depth structures are difficult to meet the requirements of simultaneous acquisition of multi-layer silt samples, especially in the high-layer-deep transition zone, where sampling consistency is poor; (4) Sampling disturbance is large and environmental interference is severe: During the operation, the silt surface is significantly disturbed and the in-situ sediment structure is destroyed, affecting the authenticity of hydrological dynamics and pollutant migration modeling; (5) Difficulty in cleaning and poor reusability: The residual sludge inside the sampling device is difficult to clean, especially when the multi-module assembly is in place, which affects the accuracy of subsequent samples and the life of the equipment; (6) Fixed angle and low spatial flexibility: Currently, most devices can only sample vertically and cannot adjust the sampling angle or implement oblique sampling according to on-site conditions, which limits their scope of application and flexibility.
[0004] Therefore, there is an urgent need to develop a river silt collection device that is modular, multi-angle adjustable, has low disturbance, is easy to clean, and adaptable to sediments with different water contents to meet the needs of modern watershed management and sediment monitoring.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 6 、 Figure 7 and Figure 9The cleaning mechanism 3 includes a slot 308, and multiple slots 308 are respectively opened on the left and right sides of the inner bottom of the tee pipe 1 and the tee pipe 2 10. The inner side of the slot 308 is engaged with a spring telescopic plate 301, and the extension of the spring telescopic plate 301 can be engaged with the slot 308 to facilitate its disassembly and assembly. The top of the spring telescopic plate 301 is rotatably connected to a cross button 302, and the bottom of the cross button 302 passes through the spring telescopic plate 301 and is fixedly connected to a positioning frame 303. Rotating the cross button 302 can synchronously drive the positioning frame 303. The front and rear sides of the outer periphery of the positioning frame 303 are fixedly connected to the scraper 304. When the positioning frame 303 rotates, it can simultaneously drive the scraper 304 to rotate. The bottom of the positioning frame 303 is fixedly connected with a cross block 305, and the cross block 305 is engaged with the cross button 302. By engaging, multiple positioning frames 303 can be fixed; Specifically, when cleaning the device after use, the cross button 302 is rotated to drive the positioning frame 303 to rotate, and the positioning frame 303 drives the scraper 304 to rotate, so that the scraper 304 is close to the inner walls of the tee pipe 1 and the tee pipe 2 10 to scrape off the attached silt; if multiple tees need to be installed, the cross button 302 is engaged with the cross block 305, and multiple positioning frames 303 can be assembled up and down without affecting the rotation operation, which is convenient for cleaning the residual silt on the inner walls of each tee.
[0028] Reference Figure 2 、 Figure 4 and Figure 5 The positioning mechanism 4 includes a bottom cover 401, which is fixedly connected to the bottom of the three-way pipe 10. The outer side of the bottom cover 401 is rotatably connected to the drilling cover 402. The front and rear sides of the outer top of the drilling cover 402 are fixedly connected to the float 403. The drilling cover 402 will be kept vertical by the buoyancy of the float 403. The inner side of the drilling cover 402 is fixedly connected to the one-way valve 215. The movement of the drilling cover 402 will simultaneously drive the one-way valve 215 to move. The top of the one-way valve 215 is connected to a hose 408. The top of the hose 408 The hose 408 is connected to the bottom cover 401 and can still not affect the material conveying of the one-way valve 215 when the drilling cover 402 rotates. The front and rear sides of the bottom of the bottom cover 401 are fixedly connected to the limit rod 407. The front and rear sides of the interior of the drilling cover 402 are fixedly connected to the hollow plate 404. The inner side of the hollow plate 404 is rotatably connected to the bidirectional threaded rod 405. The outer left and right sides of the bidirectional threaded rod 405 are threadedly connected to the baffle 406. Rotating the bidirectional threaded rod 405 can synchronously drive the baffle 406 to move along the hollow plate 404. Specifically, the drilling cover 402 can rotate around the bottom of the three-way pipe 10. During rotation, the baffles 406 on both sides of the hollow plate 404 will be restricted by the limiting rod 407, thereby limiting the rotation range of the drilling cover 402. Rotating the two-way threaded rod 405 can drive the baffle 406 to move along the hollow plate 404, thereby adjusting the limiting angle of the limiting rod 407. When the device goes deep into the water to collect, the float 403 on the drilling cover 402 will float up, so that the drilling cover 402 remains vertical. At the same time, the hose 408 can ensure that its rotation does not affect the normal operation of the one-way valve 215. Due to the restriction of the baffle 406, the drilling cover 402 can be tilted at different angles as needed, and the silt can be drilled in an inclined direction when pressure is applied.
[0029] Reference Figure 3 、 Figure 7 and Figure 8 , the left side of the connecting ring 201 is rotatably connected to a knob 210, the outer side of the knob 210 passes through the connecting ring 201 and is fixedly connected to the corresponding bevel gear 202, and rotating the knob 210 can drive the bevel gear 202 to rotate; the collecting mechanism 2 also includes a handle 211, and multiple handles 211 are respectively provided on the front and rear sides of the exterior of the tee pipe 1 and the tee pipe 2 10, and the upper and lower sides of the interior of the handle 211 are threadedly connected with screws 212. The handle 211 is threadedly connected to the tee pipe 1 and the tee pipe 2 10 through the screws 212. The handle 211 fixed by the screws 212 can facilitate operation of the device and can be removed when in use to prevent affecting the collecting operation; the collecting mechanism 2 also includes a positioning cover 213, two positioning covers 213 are respectively connected to the outer right sides of the tee pipe 1 and the tee pipe 2 10, and the inner side of the positioning cover 213 is fixedly connected with an observation window 214, through which the operation inside the device can be easily observed; Specifically, by turning the knob 210, the bevel gear 202 can be driven to rotate along the connecting ring 201. The handle 211 installed by the screw 212 can facilitate holding and carrying the device. The observation window 214 on the inside of the positioning cover 213 can facilitate real-time observation of the internal operation of the device.
[0030] Reference Figure 4 、 Figure 5 and Figure 7 The cleaning mechanism 3 also includes a filter disc 1 306, which is engaged with the outer side of the cross block 305, and a filter disc 2 307 is engaged with the inner bottom of the tee pipe 2 10. As the filter disc 1 306 and the filter disc 2 307 rotate, sludge of different fineness can be adjusted and collected; the positioning mechanism 4 also includes nuts 409, and the two nuts 409 are respectively rotatably connected to the right side of the hollow plate 404. The outer side of the nut 409 passes through the hollow plate 404 and is fixedly connected to the bidirectional threaded rod 405. Rotating the nut 409 can drive the bidirectional threaded rod 405 to rotate; Specifically, by installing filter disc 1 306 on the cross block 305 at the bottom, before the device is inserted into the sludge for sampling, the positioning frame 303 is first rotated to adjust the rotation angle of filter disc 1 306 along filter disc 2 307. By adjusting the size of the holes on filter disc 1 306 and filter disc 2 307, sludge of different fineness can be collected according to needs during use. By operating the nut 409, the bidirectional threaded rod 405 can be synchronously driven to rotate along the hollow plate 404.
[0031] Reference Figure 1 、 Figure 2 and Figure 3 A positioning ring 5 is provided on the top of the outer side of the tee pipe 1, and a connecting rod 6 is slidably connected to the inner side of the positioning ring 5. The positioning ring 5 is engaged with the tee pipe 1 through the connecting rod 6. The front and rear sides of the outer side of the connecting rod 6 are engaged with positioning pins 7. The positioning ring 5 can be fixed by plugging the connecting rod 6 and the positioning pins 7 can be used to improve the structural strength; a mounting cover 8 is engaged with the outer side of the connecting rod 6, and the top of the mounting cover 8 is provided with threaded grooves 9 all around. The threaded grooves 9 on the mounting cover 8 can facilitate the installation and fixation of the device; Specifically, by inserting the connecting rod 6 into the tee pipe 1, the positioning ring 5 and the tee pipe 1 can be fixed, so that the structural strength of the device can be improved by the connecting rod 6. At the same time, inserting the positioning pin 7 into the connecting rod 6 can improve the fixing firmness of the connecting rod 6. By inserting the mounting cover 8 on the outside of the connecting rod 6 when fixing it, the mounting cover 8 can be fixed at the same time as the positioning ring 5 is fixed. Thereafter, the device can be easily installed or connected to external equipment through the threaded groove 9 on the mounting cover 8.
[0032] Working principle: By aligning the tee pipe 1 and the tee pipe 2 10 up and down, and inserting the connecting ring 201 on the outside of their contact position, then rotating the conical gear ring 203 to drive the multiple bevel gears 202 engaged with it and the threaded block 207 on it to rotate, and as the threaded block 207 rotates, the insert block 208 is pushed to move in the connecting ring 201, so that it engages with the slots 209 on the tee pipe 1 and the tee pipe 2, thereby fixing the tee pipe 1 and the tee pipe 2, so as to assemble the corresponding number of tees according to the depth requirements. Then, align the device with the desired collection position and move it downward. The sludge will be sent into the three-way pipe through the one-way valve 215. Since the sludge can only be sent into the device through the push of the one-way valve 215, it is possible to store and retrieve sludge with different water contents. Then, as the sludge is sent into the device, it will be sent into the sampling tube 205 by gravity. After the sampling is completed, the double-threaded head rod 204 can be removed by rotating the threaded sleeve 206, and the sampling tube 205 can be taken out for testing. This can facilitate the removal of sludge of different depths and water contents and quickly remove it for testing. When the device needs to be cleaned after use, the positioning frame 303 can be driven to rotate by rotating the cross button 302, and the scraper 304 is driven to rotate as the positioning frame 303 rotates, so that the inner walls of the tee pipe 1 and the tee pipe 2 10 are cleaned by the scraper 304, preventing the attached sludge from being difficult to clean and handle. When multiple tees need to be installed, the cross button 302 can be engaged with the cross block 305 to assemble multiple positioning frames 303 up and down without affecting their rotation and operation, which can facilitate the cleaning of sludge attached to the inner wall that is difficult to wash away after use of the device. Finally, the drilling cover 402 can rotate along the bottom of the three-way pipe 10. When the drilling cover 402 rotates, the baffles 406 on both sides of the hollow plate 404 will be limited by the limit rod 407, thereby limiting the rotation range of the drilling cover 402. By rotating the two-way threaded rod 405, the baffle 406 can be driven to move along the hollow plate 404, thereby adjusting the limiting angle of the limit rod 407. When the device is used to be extended into the water for collection, the float 403 on the drilling cover 402 will float up and keep the drilling cover 402 vertical. At the same time, the hose 408 will also ensure that the rotation will not affect the operation of the one-way valve 215. At this time, it is restricted by the baffle 406, so that the drilling cover 402 can be tilted to different degrees according to needs, and as pressure is applied, the silt can be drilled in an inclined direction.
[0033] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
