[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can achieve river ecological restoration by extracting bottom silt. When the filter assembly moves, the second rotating rod can be driven to rotate by the driven assembly, thereby driving the extraction assembly to move.

DETAILED DESCRIPTION

[0033] 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.

[0034] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0035] See also Figure 1 to Figure 10In an embodiment of the present invention, a river channel silt comprehensive management ecological restoration device comprises: a treatment table 1, and a filter box 2 and a piston cylinder 3 fixedly mounted on the treatment table 1, an extraction pipe 33 and a discharge pipe 34 are fixed on the piston cylinder 3, a first rotating rod 4 is rotatably mounted on the bottom of the treatment table 1, and a plurality of impellers 5 distributed at equal intervals are fixed on the first rotating rod 4; wherein, when the river channel is managed, the treatment table 1 can be erected above the river channel, and the impeller 5 can be placed in the water, and at the same time, the extraction pipe 33 is inserted into the bottom of the river channel and contacts with the silt, and then the discharge pipe 34 is inserted into the filter box 2 to ensure that when the device is running, the extraction pipe 33 can extract the silt and transport it to the filter box 2 through the piston cylinder 3 and the discharge pipe 34, and a filter hole is opened at the bottom of the filter box 2 to discharge the water contained in the silt back into the river, and the filter hole is located above the impeller 5, and the water flow can also provide a certain impact force to the impeller 5 during the discharge process to increase the rotation speed of the impeller 5.

[0036] Also includes: See Figure 1-Figure 3 , Figure 7 , Fig.10 , a filter assembly is arranged in the filter box 2, and a symmetrically arranged filter disc 22 is connected to the filter assembly, and the filter assembly can control the filter disc 22 to move towards or away from each other, and the filter assembly includes a motor 20 fixedly mounted on the filter box 2, and a transmission rod 21 connected to the output shaft of the motor 20 is rotatably mounted on the filter box 2, and the transmission rod 21 is slidably connected to the filter disc 22; it also includes a first annular groove 2101 that is opened on the transmission rod 21 and is symmetrically arranged, a first limit block 2201 that is slidably connected to the first annular groove 2101 is fixed in the filter disc 22, and a first guide rod 23 that is slidably connected to the filter disc 22 is fixed in the filter box 2.

[0037] In detail, the first annular groove 2101 is formed by a combination of two symmetrically arranged spiral grooves, and the number of spiral turns of the spiral groove is half a turn. When the sludge is pumped into the filter box 2, the sludge needs to be dehydrated. In the initial state, the two filter discs 22 are located at the end of the stroke in the direction away from each other, and the first limit block 2201 is located at the end of the stroke on one side of the first annular groove 2101. At this time, the motor 20 works and drives the transmission rod 21 to rotate, thereby driving the first annular groove 2101 to move. The two filter discs 22 are moved along the length direction of the first guide rod 23. Since the first guide rod 23 has a guiding function, it is ensured that the filter discs 22 will not rotate with the transmission rod 21. At this time, the two filter discs 22 will move towards each other to squeeze and dehydrate the sludge, and the water will be discharged through the filter holes. Since the sludge has a certain viscosity, it may block the filter holes. During the movement of the filter discs 22, the sludge blocking the filter holes can also be pushed away to ensure the best filtering effect.

[0038] See also Figure 1 , Figure 2 , Figure 6 The second rotating rod 30 is rotatably mounted on the piston cylinder 3, and an extraction component connected to the second rotating rod 30 is provided in the piston cylinder 3, and the extraction component includes a second annular groove 3001 opened on the second rotating rod 30, and a second guide rod 32 is fixed in the piston cylinder 3, and a piston disk 31 slidably connected to the second rotating rod 30 is slidably mounted on the second guide rod 32, and a second limit block 3101 slidably connected to the second annular groove 3001 is fixed in the piston disk 31.

[0039] It should be noted that the second annular groove 3001 is also formed by a combination of two spiral grooves, and the number of spiral turns is also half a turn. Two one-way valves are arranged on the piston cylinder 3, which are respectively connected to the extraction pipe 33 and the discharge pipe 34. In the initial state, the piston disc 31 is located at the end of the stroke in the direction of the discharge pipe 34. When the sludge needs to be extracted, the second rotating rod 30 rotates and drives the second annular groove 3001 to move. Under the action of the second annular groove 3001 and the second limit block 3101, the piston disc 31 moves, and the piston disc 31 will move along the length direction of the second guide rod 32. The second guide rod 32 has a guiding function. to ensure that the piston disc 31 will not rotate with the second rotating rod 30 during movement. At this time, the air pressure in the piston cylinder 3 is reduced, so that the silt at the bottom of the river channel is sucked into the piston cylinder 3 through the extraction pipe 33. When the second limit block 3101 moves to the end of the stroke on one side of the second annular groove 3001, the amount of silt in the piston cylinder 3 is the largest. At this time, the second rotating rod 30 continues to rotate to control the piston disc 31 to move toward the initial position through the second limit block 3101 and the second annular groove 3001. Under the action of the piston disc 31, the silt is transported to the filter box 2 through the discharge pipe 34. The above steps are repeated to realize the extraction of silt.

[0040] Preferably, in order to prevent turbulence caused by excessive extraction rate, resulting in water pollution and the spread of odor on the river surface, the rotation speed of the transmission rod 21 will not be too fast, so that the rotation speed of the second rotating rod 30 will not be too fast through the driven component, and therefore, the extraction rate of the sludge will be maintained within a normal range.

[0041] See also Figure 1-Figure 3 , Figure 7 , Fig. 9 , Fig.10 , a driven component is arranged on the filter component and connected to the second rotating rod 30, and the filter component can drive the second rotating rod 30 to rotate through the driven component, and the driven component includes a follower sleeve 25 slidably mounted on the transmission rod 21, and a connecting plate 24 is slidably mounted on the follower sleeve 25, and a second movable tooth 26 is fixed to the end of the follower sleeve 25, and a fourth spring 27 is sleeved on the follower sleeve 25, and the two ends of the fourth spring 27 are respectively abutted against the follower sleeve 25 and the connecting plate 24, and also includes a second limiting tooth 28 rotatably mounted on the transmission rod 21 and cooperating with the second movable tooth 26, and the second limiting tooth 28 is sleeved with a first belt 29 connected to the second rotating rod 30.

[0042] Further, in the initial state, under the action of the centrifugal control mechanism, the control connecting plate 24 is located at the end of the stroke away from the filter box 2. Under the action of the connecting plate 24, the engagement position of the second movable tooth 26 and the second limit tooth 28 is controlled by the follower sleeve 25. At this time, the fourth spring 27 is in a compressed state. When the transmission rod 21 rotates, the follower sleeve 25 is driven to rotate synchronously, thereby driving the second movable tooth 26 to rotate. Since the second movable tooth 26 and the second limit tooth 28 are engaged with each other, the second limit tooth 28 will rotate to control the rotation of the second rotating rod 30 through the first belt 29.

[0043] Preferably, if the water flow impact force on the impeller 5 increases, the rotation speed of the impeller 5 and the first rotating rod 4 increases, thereby driving the centrifugal control mechanism to move. The centrifugal control mechanism will also drive the connecting plate 24 to move to control the follower sleeve 25 to move toward the filter box 2. At this time, the fourth spring 27 is elastically released to ensure that the second movable tooth 26 and the second limit tooth 28 always remain in a mutually engaged state. When the connecting plate 24 moves to the end of the follower sleeve 25, it means that the kinetic energy provided by the impact force of the water flow is sufficient to control the extraction pipe 33 to extract the sludge. At this time, the connecting plate 24 will control the second movable tooth 26 to move away from the second limit tooth 28 through the follower sleeve 25 to separate the second movable tooth 26 from the second limit tooth 28. When the transmission rod 21 rotates, it no longer drives the second rotating rod 30 to rotate.

[0044] See also Figure 1-Figure 5 , Figure 8 , a centrifugal control mechanism is symmetrically arranged on the first rotating rod 4 and connected to the driven component, the centrifugal control mechanism includes a support plate 6 fixedly mounted on the first rotating rod 4, a plurality of slide grooves 601 equidistantly distributed on the circumference are opened on the support plate 6, a guide column 8 is fixed in the slide groove 601, a sliding component connected to the guide column 8 is arranged on the first rotating rod 4, wherein the sliding component includes a sliding block 7 slidably mounted on the guide column 8 and slidably connected to the slide groove 601, a first spring 9 abutting against the sliding block 7 is sleeved on the guide column 8, and the first rotating rod 4 is provided with a slot 401, a movable ring 11 is slidably installed in the slot 401, the movable ring 11 is rotatably connected to the connecting plate 24, a connecting rod 10 is hinged on the movable ring 11 and is hinged to the sliding block 7, a friction structure connected to the movable ring 11 is provided on the first rotating rod 4, the friction structure mentioned above includes a first friction ring 12 fixedly installed on the movable ring 11, a second friction ring 13 abutting and cooperating with the first friction ring 12 is slidably installed on the first rotating rod 4, and a second spring 14 abutting against the second friction ring 13 is sleeved on the first rotating rod 4.

[0045] Furthermore, the centrifugal control mechanism is symmetrically arranged on the first rotating rod 4. In the initial state, the first spring 9 is in a compressed state, and the elastic potential energy of the first spring 9 is greater than the elastic potential energy of the fourth spring 27, so that the movable ring 11 is controlled to move in a direction away from the support plate 6 through the first friction ring 12 and the second friction ring 13. Under the action of the movable ring 11, the sliding block 7 is controlled by the connecting rod 10 to be located at the end of the stroke on one side of the slide groove 601. At this time, the spacing between the sliding blocks 7 is the smallest. One of the movable rings 11 will also control the connecting plate 24 to be located at the end of the stroke away from the filter box 2. The other movable ring 11 controls the transmission switching mechanism to be in a stopped working state. When the impeller 5 is placed in the water flow, under the action of the impact force of the water flow, the first rotating rod 4 is driven to rotate through the impeller 5. Under the action of the centrifugal force, The sliding block 7 moves along the length direction of the slide groove 601 and moves in the directions away from each other. The sliding block 7 will also drive the movable ring 11 to move toward the support plate 6 through the connecting rod 10, and drive the connecting plate 24 to move. The movable ring 11 will also compress the second spring 14 through the first friction ring 12 and the second friction ring 13. The movable ring 11 can also drive the transmission switching mechanism to move. When the speed of the impeller 5 reaches a certain level, one of the movable rings 11 will control the movement of the connecting plate 24 to separate the second movable tooth 26 and the second limit tooth 28. At the same time, the other movable ring 11 will control the rotation of the second rotating rod 30 through the transmission switching mechanism to convert the kinetic energy provided by the impact force of the water flow into the kinetic energy required for extracting sludge, thereby reducing the load of the motor 20 and increasing energy utilization.

[0046] Among them, if the impeller 5 rotates too fast, under the action of the two friction rings and the second spring 14, the friction of the first rotating rod 4 can be increased to slow down the rotation speed of the impeller 5, thereby preventing turbulence caused by excessive sludge extraction rate, causing water pollution and the spread of odor on the river surface.

[0047] See also Figure 1-Figure 5 , Figure 8The centrifugal control mechanism is also provided with a transmission switching mechanism connected to the second rotating rod 30, and the centrifugal control mechanism can adjust the matching state of the driven component and the filter component, and control the rotation of the second rotating rod 30 through the transmission switching mechanism, and the transmission switching mechanism includes a follower ring 17 slidably installed in the slot 401, and a fixed rod 16 fixedly connected to the movable ring 11 is fixed on the follower ring 17, and a fixed ring 1601 is fixed on the fixed rod 16. A clamping assembly connected to the fixed rod 16 is provided on the first rotating rod 4, wherein the clamping assembly includes a first movable tooth 18 slidably installed on the fixed rod 16 and matched with the fixed ring 1601, and a third spring 19 is sleeved on the fixed rod 16, and the third spring 19 is respectively abutted against the first movable tooth 18 and the follower ring 17, and a first limiting tooth 15 matching with the first movable tooth 18 is rotatably installed on the first rotating rod 4, and a second belt 35 connected to the second rotating rod 30 is sleeved on the first limiting tooth 15.

[0048] To elaborate, in the initial state, under the action of the second spring 14, the movable ring 11 is located at the end of the stroke away from the support disk 6, so that the follower ring 17 is controlled by the fixed rod 16 to be located at the end of the stroke away from the support disk 6, and the third spring 19 is in a compressed state, so that the first movable tooth 18 is in contact with the fixed ring 1601 and is in a separated state from the first limit tooth 15. As the speed of the impeller 5 increases, the movable ring 11 is driven to move toward the support disk 6, and one of the movable rings 11 will drive the connecting plate 24 to move, so that the second movable tooth 26 gradually moves in the direction away from the second limit tooth 28, and the other movable ring 11 will pass through the fixed rod 1 6 drives the follower ring 17 to move, and the fixed rod 16 also drives the fixed ring 1601 to move. At this time, the third spring 19 is elastically released and drives the first movable tooth 18 to move toward the first limit tooth 15. When the first movable tooth 18 moves to the engaged position with the first limit tooth 15, the second movable tooth 26 just moves to the separated position from the second limit tooth 28. At this time, the first belt 29 no longer drives the second rotating rod 30 to rotate, and the first movable tooth 18 will drive the first limit tooth 15 to rotate, thereby driving the second rotating rod 30 to rotate through the second belt 35. At this time, the suction of sludge is completely achieved by the rotation speed of the impeller 5 to increase the utilization rate of energy.

[0049] A construction method for a river silt comprehensive management and ecological restoration device comprises the following steps:

[0050] Step 1: Set up the treatment table 1 on the river channel and place the impeller 5 in the water surface;

[0051] Step 2: Under the action of the filter assembly, the second rotating rod 30 is driven to rotate through the driven assembly to control the movement of the extraction assembly, and the extraction assembly can transport the sludge on the riverbed to the filter box 2 through the extraction pipe 33 and the discharge pipe 34;

[0052] Step 3: The filter assembly also controls the two filter discs 22 to move toward or away from each other to filter the sludge;

[0053] Step 4: If the water flow rate is fast, the impeller 5 increases the speed of the first rotating rod 4, thereby driving the centrifugal control mechanism to move. The centrifugal control mechanism will control the driven component to no longer drive the second rotating rod 30 to rotate;

[0054] Step 5: At the same time, the centrifugal control mechanism will also drive the second rotating rod 30 to rotate through the transmission switching mechanism to extract the sludge through water flow impact.
