Description

Technical Field

[0001] This utility model belongs to the technical field of sediment treatment devices, specifically a sediment reduction device for black and odorous water bodies. Background Technology

[0002] Bottom sediment is an anaerobic sedimentary layer composed of organic pollutants, heavy metals, and sulfides. The organic pollutants in the bottom sediment produce foul-smelling gases through anaerobic fermentation, causing air pollution and threatening the health of nearby residents. Secondly, the continuous release of pollutants leads to a sharp drop in dissolved oxygen concentration in the water, disrupting the balance of the aquatic ecosystem. Therefore, bottom sediment reduction has become a key part of solving the pollution problems of rivers and lakes. At present, the mainstream method for bottom sediment treatment is cutter suction dredging, which uses a cutter to break up the bottom sediment and uses a mud pump to suck up the broken bottom sediment.

[0003] Currently, single-reamer cutters are generally used for crushing bottom sediment. However, the unidirectional rotation of the single-reamer causes the shearing force to be dispersed, making it difficult to effectively crush compacted bottom sediment. In particular, fibrous pollutants require repeated cutting, resulting in low operating efficiency. Furthermore, the unidirectional flow field generated by the unidirectional rotation easily causes mud diffusion. At the same time, fibrous pollutants such as aquatic plants are entangled on the cutter shaft due to centrifugal force on one side, leading to frequent shutdowns for cleaning. Moreover, most existing crushing aprons are fixed, which cannot adapt to changes in bottom sediment thickness and cannot process pollutants of different densities in layers. They also have poor stability under complex black and odorous water conditions. Summary of the Invention

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution: a black and odorous water body sediment reduction device, including a base 1 for support, a fixed frame 2 installed on the upper end of the base 1, a dispersing component 3 for stirring the water body sediment installed in the fixed frame 2, and a lifting component 4 for adjusting the position of the dispersing component 3 installed at the center of the upper end of the base 1.

[0021] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the dispersing assembly 3 includes a first motor 301, a rotating cylinder 302, and a rotating rod 303. The first motor 301 is fixedly connected to the bottom of the inner wall of the fixed frame 2. The rotating cylinder 302 is rotatably sleeved on one side of the bottom of the inner wall of the fixed frame 2. The rotating rod 303 is rotatably connected to one side of the top of the inner wall of the fixed frame 2. The rotating rod 303 is rotatably disposed inside the rotating cylinder 302. A first reamer 304 is fixedly connected to the lower end of the rotating rod 303. A second reamer 305 is fixedly connected to the lower part of the outer side of the rotating cylinder 302. A first bevel gear 306 is fixedly connected to the output end of the first motor 301. A second bevel gear 307 is fixedly connected to the upper part of the rotating rod 303 and the upper part of the outer side of the rotating cylinder 302. The two second bevel gears 307 are symmetrically arranged. The first bevel gear 306 and the two second bevel gears 307 mesh with each other.

[0022] Furthermore, fixing bolts are provided at the four corners of the base 1, which can be used to fix the main body of the device to the hull. During operation, the output end of the first motor 301 in the dispersing component 3 drives the first bevel gear 306 to rotate, and the two second bevel gears 307 rotate in opposite directions, which causes the rotating rod 303 and the rotating cylinder 302 to rotate in opposite directions, which causes the first cutter 304 and the second cutter 305 to rotate in opposite directions. This can significantly improve the efficiency of black and odorous water body bottom sediment reduction. The first cutter 304 and the second cutter 305 generate superimposed shearing force through counter-rotation, which improves the efficiency of breaking up the hardened bottom sediment. At the same time, the mud diffusion range is reduced by the counter-rotation of the flow field, and when rotating in opposite directions, impurities are thrown away from the cutter shaft by the bidirectional centrifugal force, preventing water plants from getting entangled, thereby significantly reducing the number of times the device needs to be stopped for cleaning.

[0023] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the lifting assembly 4 includes a fixed cylinder 401 and a lifting rod 402. The fixed cylinder 401 is fixedly connected to the upper center of the base 1, and the lifting rod 402 is fixedly connected to the lower end of the base 1 and slidably connected inside the fixed cylinder 401. A rotating cavity 403 is provided inside the fixed cylinder 401. A worm gear 404 and a worm 405 are rotatably connected to the inner wall of the rotating cavity 403. The worm gear 404 and the worm 405 mesh with each other. A threaded rod 406 is rotatably connected to the bottom of the inner wall of the fixed cylinder 401. The threaded rod 406 is threadedly connected to the inside of the lifting rod 402. The output end of the worm gear 404 passes through the top of the inner wall of the rotating cavity 403 and is fixedly connected to the lower end of the threaded rod 406. A second motor 407 is fixedly connected to the lower side wall of the fixed cylinder 401. The output end of the second motor 407 passes through the fixed cylinder 401 and is fixedly connected to one end of the worm 405.

[0024] Furthermore, during the processing, the second motor 407 drives the worm gear 405 to rotate via the lifting assembly 4, and the worm wheel 404 rotates within the rotating cavity 403, causing the threaded rod 406 to rotate within the fixed cylinder 401. This allows the lifting rod 402 to lift and lower, enabling the adjustment of the height of the first cutter 304 and the second cutter 305. This allows the device to not only adjust the cutting depth according to the thickness of the bottom sediment, but also to process pollutants of different densities in layers, improving the crushing efficiency and ensuring continuous and stable operation of the device in complex black and odorous water bodies. This significantly improves the treatment effect of the device. Moreover, the self-locking characteristic between the worm wheel 404 and the worm gear 405 can lock the threaded rod 406, preventing the threaded rod 406 from spinning due to external interference.

[0025] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 4As shown, a protective shell 5 is fixedly connected to the upper end of the base 1. Both sides of the protective shell 5 are provided with heat dissipation vents. One end of the protective shell 5 is fixedly connected to the side wall of the fixed cylinder 401. The second motor 407 is located inside the protective shell 5.

[0026] Furthermore, the protective shell 5 can further protect the second motor 407 and prevent the second motor 407 from being damaged by external interference.

[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, telescopic rods 6 are fixedly connected to the four corners of the upper end of the base 1, and the upper ends of the four telescopic rods 6 are fixedly connected to the lower end face of the fixed frame 2.

[0028] Furthermore, the fixed end of the telescopic rod 6 is fixedly connected to the upper end of the base 1, and the telescopic end of the telescopic rod 6 is fixedly connected to the lower end of the fixed frame 2. The telescopic rod 6 guides the lifting and lowering of the fixed frame 2, so that the fixed frame 2 can be lifted and lowered stably.

[0029] As one implementation method in this embodiment, please refer to Figure 4 As shown, the inner wall of the fixed cylinder 401 has two symmetrically arranged limiting grooves 7, and the inner walls of the two limiting grooves 7 are slidably connected to limiting blocks 8. The two limiting blocks 8 are respectively fixedly connected to the two side walls of the lifting rod 402.

[0030] Furthermore, the limiting block 8, in conjunction with the limiting groove 7, can limit the lifting stroke of the lifting rod 402, preventing the lifting rod 402 from overshooting and disengaging from the threaded rod 406, thus ensuring the stable operation of the device.

[0031] Working principle: The device is installed on the hull. During operation, the output of the first motor 301 in the dispersing component 3 drives the first bevel gear 306 to rotate, and the two second bevel gears 307 rotate in opposite directions. This causes the rotating rod 303 and the rotating cylinder 302 to rotate in opposite directions, which in turn causes the first cutter 304 and the second cutter 305 to rotate in opposite directions. This significantly improves the efficiency of removing bottom sediment from black and odorous water bodies. The opposing rotation of the first cutter 304 and the second cutter 305 generates superimposed shearing forces, which improves the efficiency of breaking up compacted bottom sediment. At the same time, the flow field counteracts the mud diffusion range, and during the reverse rotation, impurities are thrown off the cutter shaft by bidirectional centrifugal force. To prevent aquatic plants from tangling and thus significantly reduce the number of times the device needs to be shut down for cleaning, during the treatment process, the second motor 407 drives the worm gear 405 to rotate via the lifting assembly 4. The worm wheel 404 rotates in the rotating cavity 403, causing the threaded rod 406 to rotate in the fixed cylinder 401. This allows the lifting rod 402 to be raised and lowered, enabling the adjustment of the height of the first cutter 304 and the second cutter 305. This allows the device to not only adjust the cutting depth according to the thickness of the bottom sediment, but also to process pollutants of different densities in layers, improving the crushing efficiency and ensuring continuous and stable operation of the device in complex black and odorous water bodies, significantly improving the treatment effect of the device.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
