[0038] Also includes: See Figure 1-Figure 6 , a reciprocating cleaning mechanism is arranged on the first partition 1 and the second partition 2, and a cleaning plate 9 and a cleaning brush 10 are connected to the reciprocating cleaning mechanism, and the reciprocating cleaning mechanism can drive the cleaning plate 9 and the cleaning brush 10 to reciprocate along the length direction of the first screening slot 101 and the second screening slot 201, and the reciprocating cleaning mechanism includes pulleys 3 that are rotatably installed on the first partition 1 and the second partition 2 and are symmetrically arranged, and a conveyor belt 4 is sleeved on the pulley 3, and a limiting column 5 is fixed on the conveyor belt 4. The first partition 1 and the second partition 2 are provided with a guide assembly connected with the limiting column 5, wherein the guide assembly includes guide columns 6 that are respectively fixedly installed on the first partition 1 and the second partition 2, and a guide sleeve 7 is slidably installed on the guide column 6, and a movable plate 8 is fixed on the side wall of the guide sleeve 7, and a card slot 801 that is slidably connected with the limiting column 5 is opened on the movable plate 8, and the cleaning plate 9 passes through the first through slot 102 and is fixedly connected with the guide sleeve 7.

[0039] In detail, as the river water flows, the impurities mixed in the river water will move along. When the river flows through the first partition plate 1 and the second partition plate 2, under the action of the first screening slot 101 and the second screening slot 201, impurities of different sizes will be blocked in front of the two first partition plates 1 and the second partition plates 2 respectively. In order to prevent the first screening slot 101 and the second screening slot 201 from filtering the impurities, the first screening slot 101 and the second screening slot 201 are blocked due to excessive accumulation of impurities on the first partition plate 1 and the second partition plate 2. It is necessary to clean the impurities at the front end of the first partition plate 1 and the second partition plate 2 in time. In the initial state, the limit column 5 is located at the end of the stroke toward the bottom of the first partition plate 1 and the second partition plate 2. Under the action of the limit column 5 and the slot 801, the movable plate 8 is located at the end of the stroke toward the side of the guide column 6, so that the cleaning plate 9 is controlled by the guide sleeve 7 to be located at the end of the stroke on the side of the first screening slot 101 and the second screening slot 201. When it is necessary to clean the impurities, the pulley 3 will rotate and pass The conveyor belt 4 drives the limit column 5 to move. Under the action of the limit column 5 and the slot 801, the movable plate 8 moves to control the guide sleeve 7 to move along the length direction of the guide column 6. The guide sleeve 7 will also drive the cleaning plate 9 to move along the length direction of the first through slot 102. The first through slot 102 has a guiding function to ensure that the guide sleeve 7 will not deviate during movement. The cleaning plate 9 will move along the length direction of the first screening slot 101 and the second screening slot 201 to clean the impurities blocking the first partition 1 and the second partition 2. Under the action of the cleaning plate 9, the impurities will gradually be pushed toward the first partition 1 and the second partition 2 until the cleaning plate 9 moves to the position cooperating with the push plate 21. Under the action of the pushing mechanism, the impurities on the cleaning plate 9 are pushed into the storage box. At this time, the cleaning plate 9 moves to the end of the stroke on the other side of the first screening slot 101 and the second screening slot 201, and the pulley 3 continues to move to control the cleaning plate 9 to move toward the initial position. Repeat the above steps to achieve the cleaning of impurities.

[0040] Among them, the cleaning brush 10 is in contact with the surface of the first partition plate 1 and the second partition plate 2. As the cleaning plate 9 moves, the cleaning brush 10 can also be driven to move synchronously. Under the action of the cleaning brush 10, the impurities remaining on the surface of the first partition plate 1 and the second partition plate 2 are cleaned.

[0041] See also Figure 3-Figure 7, a conduction mechanism is arranged on the first baffle plate 1 and the second baffle plate 2 and connected to the reciprocating cleaning mechanism, the conduction mechanism is connected with a conduction plate 14 that cooperates with the first screening slot 101 and the second screening slot 201, the conduction mechanism can be actuated when the reciprocating cleaning mechanism moves, and drives the conduction plate 14 to perform a conduction action on the first screening slot 101 and the second screening slot 201, the conduction mechanism includes a connecting plate 11 fixedly mounted on the side wall of the guide sleeve 7, and the connecting plate 11 is fixed with equidistant A plurality of support sleeves 12 are distributed, a support rod 13 is slidably installed in the support sleeve 12, the support rod 13 is fixedly connected to the conduction plate 14, a guide assembly connected to the first partition 1 and the second partition 2 is provided on the support rod 13, wherein the guide assembly includes corrugated grooves 17 respectively provided on the first partition 1 and the second partition 2, a support plate 15 is fixed to the end of the support rod 13 away from the conduction plate 14, and a support column 16 slidably connected to the corrugated groove 17 is fixed on the support plate 15.

[0042] It should be noted that, as the screening time increases, some impurities that are just the same size as the first screening slot 101 and the second screening slot 201 will be stuck in the first screening slot 101 and the second screening slot 201. If the water flow rate is low, the impact force provided to the impurities cannot flush the impurities out of the first screening slot 101 and the second screening slot 201, which will cause the first screening slot 101 and the second screening slot 201 to be blocked, resulting in the problem of poor river management effect. Therefore, it is necessary to conduct the first screening slot 101 and the second screening slot 201. The corrugated groove 17 is arranged in a wave shape. In the initial state, the guide sleeve 7 is located at the end of the stroke on one side of the guide column 6, and the support column 16 is located at the end of the stroke on one side of the corrugated groove 17, so that the support rod 13 extends out of the support sleeve 12 to the maximum extent. At this time, the conduction plate 14 is located in the first screening slot 10 1 and the second screening groove 201, when the pulley 3 rotates, the guide sleeve 7 will move along the length direction of the guide column 6, thereby driving the connecting plate 11 to move along the length direction of the second through groove 103, and the connecting plate 11 will also drive the support sleeve 12 to move, thereby driving the support rod 13 to move, under the action of the support rod 13, the support plate 15 is controlled to move, so as to control the support column 16 to slide along the trajectory of the corrugated groove 17, under the action of the corrugated groove 17 and the support column 16, the support rod 13 is made to reciprocate along the length direction of the support sleeve 12, thereby driving the conducting plate 14 to continuously enter and exit the first screening groove 101 and the second screening groove 201, so as to clean the impurities stuck in the first screening groove 101 and the second screening groove 201, and ensure that the first screening groove 101 and the second screening groove 201 are always in a conducting state.

[0043] See also Figure 1-Figure 3 , Figure 8 , Fig. 9 , a pushing mechanism is arranged on the first partition plate 1 and the second partition plate 2, and the pushing mechanism is respectively connected to the first storage box 22 and the second storage box 29, and the pushing mechanism is also connected to the pushing plate 21, and the pushing mechanism can be actuated when the cleaning plate 9 moves to abutting position with the pushing plate 21, so as to push the impurities on the cleaning plate 9 into the first storage box 22 and the second storage box 29 through the pushing plate 21, and the pushing mechanism includes fixing plates respectively fixedly installed on the first partition plate 1 and the second partition plate 2 18, the fixed plate 18 is fixedly connected to the first storage box 22 and the second storage box 29 respectively, and a groove 1801 and an inclined groove 1802 are opened on the fixed plate 18, and the groove 1801 and the inclined groove 1802 are connected to each other. A sliding assembly is arranged in the groove 1801, wherein the sliding assembly includes a sliding block 19 slidably installed in the groove 1801, and a receiving rod 20 slidably connected to the inclined groove 1802 is fixed on the sliding block 19, and the receiving rod 20 is fixedly connected to the push plate 21.

[0044] Furthermore, the groove 1801 and the inclined groove 1802 are both arranged in an inclined shape, and the inclination angles are the same. In the initial state, under the action of gravity, the sliding block 19 is located at the end of the stroke of the groove 1801 toward the cleaning plate 9 side, and the receiving rod 20 is located at the end of the stroke on the side of the inclined groove 1802, so that the push plate 21 is located at the end of the stroke toward the bottom of the first partition 1 and the second partition 2. At this time, the push plate 21 is located above the water surface and above the first storage box 22 and the second storage box 29. When the cleaning plate 9 moves toward the push plate 21, under the action of the cleaning plate 9, the impurities blocking the front of the first partition 1 and the second partition 2 can be cleaned. When the cleaning plate 9 moves to the position in contact with the push plate 21, the push plate 21 will be located at the end of the stroke of the cleaning plate 9 toward the first screening slot 101 and the second screening slot 201. The cleaning plate 9 continues to move. Continue to move, and drive the receiving rod 20 to move along the length direction of the inclined groove 1802 through the push plate 21, so as to drive the sliding block 19 to move along the length direction of the groove 1801. Under the action of the groove 1801 and the sliding block 19, it is ensured that the push plate 21 will not deviate during movement. Under the action of the inclined groove 1802 and the receiving rod 20, the push plate 21 will also move in the direction away from the first screening groove 101 and the second screening groove 201 while fitting the cleaning plate 9, so as to push the impurities on the cleaning plate 9 toward the first storage box 22 and the second storage box 29. When the sliding block 19 moves to the end of the stroke on the other side of the groove 1801, the cleaning plate 9 also moves to the end of the stroke, and the impurities on the cleaning plate 9 will be completely pushed into the first storage box 22 and the second storage box 29. Repeat the above steps to achieve the effect of storing the screened impurities.

[0045] See also Figure 1 , Figure 2 , Figure 8 , Fig.10 A filter press mechanism is provided on the first storage box 22 and the second storage box 29, and the filter press mechanism includes a fixed sleeve 25 fixedly installed on the first storage box 22 and the second storage box 29 respectively, and a movable rod 26 is slidably installed in the fixed sleeve 25, and an extrusion plate 28 is fixed at the end of the movable rod 26. A spring 27 is sleeved on the fixed sleeve 25 and the movable rod 26, wherein the filter press mechanism also includes a rotating rod 23 rotatably installed in the first storage box 22 and the second storage box 29 respectively, and a symmetrically arranged cam 24 is fixed on the rotating rod 23, and the cam 24 is in contact with the extrusion plate 28.

[0046] Furthermore, a filter groove 2201 is provided at the bottom of the first storage box 22 and the second storage box 29. In order to ensure the subsequent processing of impurities, the impurities need to be dehydrated. In the initial state, the short axis of the cam 24 is in contact with one side of the extrusion plate 28, and the spring 27 is in a compressed state, so that the movable rod 26 is located at the end of the stroke away from the first storage box 22 and the second storage box 29, so as to ensure that the extrusion plate 28 is always in contact with the cam 24. When it is necessary to filter the impurities, the rotating rod 23 will rotate, thereby driving the cam 24 to rotate. Under the action of the cam 24, the extrusion plate 28 is driven toward the first storage box 22 and the second storage box 29. When a partition 1 and a second partition 2 move in the same direction, the extrusion plate 28 will also drive the movable rod 26 to move along the length direction of the fixed sleeve 25 and compress the spring 27. Under the action of the extrusion plate 28, the impurities are filtered out, and the water remaining in the impurities will flow back into the river through the filter tank 2201. When the short axis of the cam 24 abuts against the extrusion plate 28 again, the extrusion plate 28 is reset under the action of the spring 27, and the above steps are repeated to achieve the effect of continuous filtering of the impurities. After filtering, the storage capacity of the first storage box 22 and the second storage box 29 for impurities can also be increased.

[0047] A method for ecological restoration of small and medium-sized rivers based on double-layer enclosures comprises the following steps:

[0048] Step 1: placing the first separator 1 and the second separator 2 in the river channel, and screening impurities of different sizes under the action of the first screening slot 101 and the second screening slot 201;

[0049] Step 2: In order to ensure that the first screening slot 101 and the second screening slot 201 are not blocked, the cleaning plate 9 is driven to move along the length direction of the first screening slot 101 and the second screening slot 201 under the action of the reciprocating cleaning mechanism to clean the impurities;

[0050] Step 3: At the same time, the reciprocating cleaning mechanism also drives the conduction mechanism to move, and controls the conduction plate 14 to reciprocate in the first screening slot 101 and the second screening slot 201, so as to push the impurities stuck in the first screening slot 101 and the second screening slot 201 onto the cleaning plate 9;

[0051] Step 4: When the cleaning plate 9 moves to the abutting position with the push plate 21, the push plate 21 will drive the pushing mechanism to move, thereby controlling the movement of the push plate 21 to push the impurities on the cleaning plate 9 into the first storage box 22 and the second storage box 29;

[0052] Step 5: At this time, under the action of the filter press mechanism, the impurities in the first storage box 22 and the second storage box 29 are subjected to filter press treatment, so that the water in the impurities flows back into the river again.
