In the silt, stones with larger mass and volume are generally located at the bottom of the silt, while objects with smaller mass such as plastic sheets and branches are generally located in the upper layer of the silt. Therefore, large sundries are salvaged by the salvage components, and small sundries are salvaged by the cooperation of the salvage components and the filter plates.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the present invention provides a sludge treatment device for water ecological restoration, including a floating mechanism 1 composed of a floating block 101 and a connecting block 102, wherein the connecting block 102 is symmetrically installed on the inner side of the floating block 101, and further includes:

[0034] A connecting mechanism 2, which is arranged on the inner side of the connecting block 102;

[0035] A storage mechanism 3, which is disposed at the bottom of the connecting mechanism 2 and is used to store debris in the sludge;

[0036] The processing mechanism 4 is arranged at the bottom of the connecting mechanism 2 and is used to salvage the debris in the sludge;

[0037] A collecting mechanism 5, which is disposed on one side of the storage mechanism 3 and is used to transport the debris salvaged by the processing mechanism 4 to the interior of the storage mechanism 3;

[0038] Among them, the processing mechanism 4 includes a connecting roller 401, a guide block 402, a salvage component 403 and a filter plate 404. One end of the connecting roller 401 is provided with a waterproof motor installed inside the connecting mechanism 2. The connecting roller 401 is rotatably connected to the connecting mechanism 2. The guide block 402 and the salvage component 403 are both annularly fixed on the surface of the connecting roller 401. The filter plate 404 is fixedly installed between adjacent salvage components 403 along the axial direction of the connecting roller 401.

[0039] The above scheme is adopted: the connection roller 401 is driven to rotate by a waterproof motor, thereby driving the salvage component 403 and the filter plate 404 and other structures thereon to rotate, so that the salvage component 403 and the filter plate 404 can penetrate into the silt, and the debris in the silt is salvaged by the multiple salvage components 403 and the filter plate 404. In the silt, stones with larger mass and volume are generally located at the bottom of the silt, while objects with smaller mass such as plastic sheets and branches are generally located in the upper layer of the silt. Therefore, large debris is salvaged by the salvage component 403, and small debris is salvaged by the cooperation of the salvage component 403 and the filter plate 404. In addition, since the salvage components 403 are arranged at intervals, the passage of silt can also be facilitated.

[0040] like Figure 2 As shown, the connecting mechanism 2 includes a first connecting frame 201, a guide frame 202, a connecting block 203 and a connecting rod 204. The first connecting frame 201 is slidably connected to the connecting block 102. The guide frame 202, the connecting block 203 and the connecting rod 204 are all fixedly mounted on the surface of the first connecting frame 201. The waterproof motor is installed inside the guide frame 202 and the connecting roller 401 is rotatably connected to the guide frame 202.

[0041] The above scheme is adopted: when the processing mechanism 4 encounters a riverbed when salvaging debris, due to the hard riverbed, the salvage component 403 is subjected to an upward reaction force when rotating, so that the connecting mechanism 2 as a whole moves upward inside the floating block 101, which has a buffering effect, and the floating block 101 floats on the water surface and can be driven by an external power to move the device as a whole, so as to facilitate the treatment of silt in different areas. The setting of the external power can be referenced by existing technologies such as ships.

[0042] like Figure 3 As shown, the storage mechanism 3 includes a collection bin 301 and a positioning block 302 . The collection bin 301 is fixedly connected to the first connecting frame 201 via a connecting rod 204 . The positioning block 302 is fixedly installed at a corner of the collection bin 301 . A filter is provided at the bottom of the collection bin 301 .

[0043] The above scheme is adopted: the filter screen set at the bottom of the collecting bin 301 can facilitate the passage of attached silt when storing debris in the silt, preventing the silt from being carried. When the device is moved, water can enter from the opening of the collecting bin 301 and be discharged from the bottom filter screen. The water flow can prevent the debris in the silt from leaking out and can also further clean the debris in the silt.

[0044] like Figure 5 , 6 As shown, the collecting mechanism 5 includes a second connecting frame 501, a first movable plate 502, a second movable plate 503, a spring sleeve 504, a corrugated plate 505 and a spring 506. The second connecting frame 501 slides inside the connecting block 203 and the positioning block 302 and fits against the surface of the collecting bin 301. The first movable plate 502, the second movable plate 503 and the second connecting frame 501 are hinged to each other. Both ends of the spring sleeve 504 are fixedly mounted on the surfaces of the second connecting frame 501 and the first movable plate 502, respectively. Both ends of the corrugated plate 505 are fixedly mounted on the surfaces of the second connecting frame 501 and the first movable plate 502, respectively. The spring 506 is arranged on the surface of the second connecting frame 501 and is located between the connecting block 203 and the positioning block 302. One end of the spring 506 close to the second movable plate 503 is fixedly connected to the second connecting frame 501. When the second movable plate 503 is located at the opening of the collecting bin 301, it can flip toward the inside of the collecting bin 301 under the action of gravity.

[0045] By adopting the above scheme: the second connecting frame 501 has a tendency to move toward the connecting roller 401 through the fixation of the spring 506 and the second connecting frame 501, and an acute-angle bin body can be formed between the first movable plate 502, the second movable plate 503 and the corrugated plate 505, and the bin body can store the salvaged plastic fragments of smaller volume to prevent the leakage of smaller debris during the transportation, and when the second movable plate 503 is turned over, all the debris limited by it can fall into the collection bin 301, so as to achieve the effect of collecting the debris.

[0046] like Figure 4 , 5 As shown in Figure 6, the maximum unfolding angle between the second connecting frame 501 and the first movable plate 502 is one hundred and eighty degrees, and the minimum unfolding angle is forty-five degrees. The ball 5022 can slide along the inner surface of the concave structure formed by the guide block 402, the connecting roller 401, the connecting seat 4031 and the guide rod 410 in sequence.

[0047] The above scheme is adopted: the spring sleeve 504 is set to make the second connecting frame 501 and the first movable plate 502 have a tendency to expand to 180 degrees. When the first movable plate 502 moves toward the connecting roller 401 under the elastic force of the spring 506, the first movable plate 502 slides along the inner surface of the concave structure formed by the guide block 402, the connecting roller 401, the connecting seat 4031 and the guide rod 410 in sequence, and the expansion angle between the second connecting frame 501 and the first movable plate 502 is gradually reduced to 45 degrees. As the connecting roller 401 drives the salvage assembly 403 to rotate, the first movable plate 502 is pressed by the guide rod 410. The squeezing of 502 can make the collecting mechanism 5 as a whole move obliquely upward along the axial direction of the second connecting frame 501 until the guide rod 410 passes over the first movable plate 502. At this time, the second movable plate 503 is turned over into the collecting bin 301 to transport the debris; further, when the first movable plate 502 slides along the inner surface of the concave structure formed by the guide block 402, the connecting roller 401, the connecting seat 4031 and the guide rod 410, the smaller debris salvaged by the salvaging assembly 403 can be transferred to the bin body formed between the first movable plate 502, the second movable plate 503 and the corrugated plate 505 to prevent the omission of debris.

[0048] like Figure 6 As shown, the first movable plate 502 includes a plate body 5021 and a ball bearing 5022 . The plate body 5021 is hinged to the second connecting frame 501 and the second movable plate 503 . The ball bearing 5022 is rotatably connected to both ends of the plate body 5021 .

[0049] By adopting the above solution, the provided balls 5022 can reduce the friction force during movement, thereby ensuring that the first movable plate 502 can be easily turned over under pressure.

[0050] like Figure 7 As shown, the salvage assembly 403 includes a connecting seat 4031, a connecting shaft 4032, a salvage rod 4033 and a torsion spring 4034. The connecting seat 4031 is fixedly connected to the connecting roller 401. The connecting seat 4031 is hinged to the salvage rod 4033 through the connecting shaft 4032. The torsion spring 4034 is symmetrically arranged on the surface of the connecting shaft 4032 and its two ends are fixedly connected to the connecting seat 4031 and the salvage rod 4033 respectively.

[0051] The above scheme is adopted: the connecting seat 4031 and the salvage rod 4033 are able to rotate, and the tension is provided by the torsion spring 4034. When salvaging heavy objects such as large rocks, the salvage rod 4033 and the connecting seat 4031 tend to be coaxial in the length direction due to the influence of the heavy objects. When the connecting seat 4031 and the salvage rod 4033 rotate to the top of the connecting roller 401, the salvage rod 4033 has a tendency to push the rocks into the collection bin 301 under the action of the torsion spring 4034, which is convenient for collecting larger debris. When the salvage rod 4033 contacts the riverbed, it can also be buffered by rotation to prevent damage.

[0052] like Figure 7 As shown, guide rods 410 are also installed on the salvage components 403 located at both ends of the connecting roller 401 in the axial direction, the guide block 402 and the salvage component 403 are in contact with each other, and the guide rods 410 are fixedly installed on the surface of the salvage rod 4033 .

[0053] By adopting the above scheme, the guide rod 410 can play a certain limiting effect when salvaging larger stones, preventing the stones from falling off from the side, and can also guide the first movable plate 502; the guide block 402 and the salvage assembly 403 fit together, so that the first movable plate 502 can slide smoothly between the two, ensuring the stability of the structure.

[0054] like Figure 7 As shown, the maximum rotation angle of the connecting seat 4031 and the salvage rod 4033 is thirty degrees, the salvage rod 4033 is arc-shaped, and the connecting seat 4031 and the salvage rod 4033 together form a concave shape.

[0055] With the above solution, the arc shape of the salvage rod 4033 can facilitate the salvage of the stone and prevent it from falling off.

[0056] The working principle and use process of the present invention:

[0057] When in use, first start the waterproof motor to drive the connecting roller 401 to rotate. The rotation of the connecting roller 401 can drive the guide block 402, the salvage assembly 403 and the filter plate 404 to rotate synchronously. When the salvage assembly 403 rotates, the first movable plate 502 can be squeezed by the guide rod 410 to form a forty-five degree angle between the first movable plate 502 and the second connecting frame 501. Then, the squeezing of the first movable plate 502 by the connecting roller 401 can drive the collecting mechanism 5 to move along the opening surface of the collecting bin 301 as a whole. When the second movable plate 503 moves to the opening of the collecting bin 301, the second movable plate 503 is not limited by the outer contour of the collecting bin 301. At this time, the second movable plate 503 is affected by gravity and the thrust of the salvage rod 4033 on the debris. The second movable plate 503 flips into the inside of the collecting bin 301, and the debris also enters the inside of the collecting bin 301.

[0058] After the connecting roller 401 continues to rotate so that the salvage rod 4033 passes over the first movable plate 502, the elastic force of the spring 506 causes the second connecting frame 501 to drive the first movable plate 502 and the second movable plate 503 to move toward the connecting roller 401. Synchronously, because they are not squeezed by the guide rod 410, the second connecting frame 501 and the first movable plate 502 are unfolded 180 degrees under the action of the spring sleeve 504, and the second movable plate 503 is also parallel to the second connecting frame 501. During the movement of the first movable plate 502 toward the connecting roller 401, the first movable plate 502 slides along the inner surface of the concave structure formed by the guide block 402, the connecting roller 401, the connecting seat 4031 and the guide rod 410, and the small-volume debris is transferred into the bin formed between the first movable plate 502, the second movable plate 503 and the corrugated plate 505.

[0059] The connecting roller 401 continues to rotate, and the first movable plate 502 is squeezed by the rotating guide rod 410 again, forming a cycle.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0061] 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.
