[0043] The following is a further detailed description through specific embodiments:

[0044] Embodiment 1:

[0045] As shown in the attached Figures 1 to 7 figure: A river channel environment restoration device includes a floating block 1 for floating on the water surface. Below the floating block 1, there is an aeration mechanism for aerating water surface floating objects. The aeration mechanism includes a blower 8 for pumping gas and an air distribution pipe 81 for transporting gas. In this embodiment, both the blower 8 and the aeration mechanism belong to the prior art and will not be elaborated in this embodiment; a stacking channel 11 is opened on the floating block 1, and a lifting mechanism for filtering water surface floating objects is arranged in the stacking channel 11. The lifting mechanism is located above the air distribution pipe 81.

[0046] Among them, the lifting mechanism includes a sliding rod 2 located inside the stacking channel 11. The blower 8 is located inside the floating block 1. One end of the air supply pipe 81 is communicated with the output end of the blower 8, and the end of the air supply pipe 81 away from the blower 8 is located on the sliding rod 2. A sliding block 21 is slidably fitted inside the sliding rod 2, and an oval collecting bag 22 is rotatably fitted on the sliding block 21. In this embodiment, the collecting bag 22 is made of a deformable rubber layer. A plurality of filter meshes 72 for collecting floating substances in the river water are arranged on the side of the collecting bag 22 away from the sliding block 21. A plurality of circumferentially arranged connecting grooves 24 are formed on the sliding rod 2, and the collecting grooves are located in the connecting grooves 24. The center of the sliding block 21 is communicated with the storage bag 20, and one end of the storage bag 20 away from the sliding block 21 is slidably fitted with the sliding rod 2. A collecting chamber 63 is formed at the center of the sliding block 21, and a one-way valve 6 is communicated between the collecting chamber 63 and the storage bag 20. The top of the collecting chamber 63 is concave, and a water pipe 61 is communicated between the collecting chamber 63 and the collecting bag 22. A conical block 62 in an arc shape is arranged between the one-way valve 6 and the water pipe 61. The conical block 62 is welded to the floating block 1, and the end of the conical block 62 away from the storage bag 20 points to the water pipe 61. A conical chamber is formed between the one-way valve 6 and the water pipe 61, and the conical chamber is communicated with the collecting chamber 63.

[0047] A storage bag 20 for collecting the gas conveyed by the air supply pipe is also slidably fitted in the stacking channel 11. The storage bag 20 drives the lifting mechanism to move above the floating block 1 based on the gas inside the storage bag 20. A weight block 23 in a horn shape is welded to the bottom of the sliding rod 2. The diameter of the side of the weight block 23 away from the sliding plate is larger than the diameter of the side of the weight block 23 close to the sliding plate. An electromagnet 25 for changing the direction of the magnetic field is bonded to the top of the sliding rod 2. The electromagnet 25 is electrically connected to a control panel (not shown in the figure) for inputting the working program of the electromagnet 25. A magnet block is bonded to the top of the sliding block 21, and the magnet block is slidably fitted with the sliding rod 2. And the storage bag 20 is communicated with a pressure valve (not shown in the figure).

[0048] A discharge slot is formed on the side of the collecting bag 22 close to the sliding rod 2. A sliding plate 7 is slidably fitted in the discharge slot. A spring is welded between the sliding plate 7 and the collecting bag 22. A hook 71 is welded to the sliding plate 7. When the sliding plate 7 is in the initial state, the sliding plate 7 closes the discharge slot. When the hook 71 abuts against the floating block 1, the sliding plate 7 opens the discharge slot.

[0049] Above the lifting mechanism, there is a purification mechanism for filtering garbage in river water. The purification mechanism includes a filter plate 5 that rotates in cooperation with the floating block 1. A rotating shaft 51 is welded at the center of the filter plate 5, and the rotating shaft 51 rotates in cooperation with the floating block 1; the filter plate 5 is located on the side of the rotating shaft 51 away from the sliding rod 2. On the side of the rotating shaft 51 close to the sliding rod 2, a collection tank 52 is welded. A number of through holes (not shown in the figure) are opened on the collection tank 52. The collection tank 52 is located below the filter plate 5, and a guiding plate is welded between the collection tank 52 and the filter plate 5; when the filter plate 5 is in the initial state, the collection tank 52 is located on both sides of the sliding rod 2, and the height of the filter plate 5 is lower than the height of the rotating shaft 51. When the collection bag 22 abuts against the collection tank 52, the filter plate 5 is parallel to the rotating shaft 51.

[0050] The specific implementation process is as follows:

[0051] In the initial state, the floating block 1 floats on the water surface, the collection bag 22 and the sliding block 21 sink to the bottom of the water. Both ends of the collection bag 22 communicate with the outside through the filter net 72. The aeration component aerates the water body through the aeration pipe 81 on the sliding rod 2. The water floating objects in the water body move upward with the bubbles and enter the inside of the collection chamber 63. Since the conical chamber is located between the one-way valve 6 and the water pipe 61, part of the gas will accumulate in the conical chamber, reducing the entry of the river water and water floating objects inside the collection chamber 63 into the storage bag 20. The accumulated gas gradually enters the storage bag 20 when contacting the one-way valve 6; during the movement of the river water and water floating objects with the bubbles, when the river water and water floating objects contact the conical block 62, the water flow is guided by the conical block 62 to flow towards the water pipe 61, so that the river water and water floating objects enter the inside of the collection bag 22 for filtration, and the water floating objects in the river water are restricted by the filter net 72 and remain inside the collection bag 22.

[0052] The floating block 1 continues to float on the water surface. Since the height of the filter plate 5 is lower than the height of the rotating shaft 51, an inclined filter plate 5 is formed to intercept and collect the garbage on the water surface. When the sliding block 21 drives the collection bag 22 to move upward, the collection bag 22 squeezes open the collection tank 52, which is convenient for pushing the filter plate 5 to rotate around the rotating shaft 51, making the filter plate 5 horizontal with the rotating shaft 51, facilitating the garbage collected on the filter plate 5 to fall into the inside of the collection tank 52 to reduce the garbage on the river surface; it is also convenient to use the reaction force of the collection tank 52 on the collection bag 22 to squeeze the collection bag 22 to fit against the sliding rod 2, and then it is convenient for the collection bag 22 to pass through the accumulation channel 11, improving the smoothness of the whole process.

[0053] When collecting the gas generated during the aeration process in the storage bladder 20, through the weight adjustment of the counterweight 23, the center of gravity of the floating block 1 is increased to provide the stability of the floating block, and the sliding rod 2 is kept perpendicular to the water surface to facilitate the treatment of waterborne floating objects. As the gas collected inside the storage bladder 20 continuously increases, the internal pressure of the storage bladder 20 continuously increases, and the buoyancy generated by the storage bladder 20 in the river water is also greater, so as to overcome the gravity of the sliding block 21 and the collection bladder 22, making the storage bladder 20 move towards the top of the sliding rod 2. At this time, the control panel activates the electromagnet 25, and the suction force of the electromagnet 25 continuously drives the magnet block on the top of the sliding block 21 to move, so that the sliding block 21 squeezes the storage bladder 20, making the internal pressure of the storage bladder 20 continuously increase to overcome the limitation of the pressure valve, facilitating the reduction of the storage bladder 20 for reuse; when the electromagnet 25 subsequently generates a magnetic field in the opposite direction to the magnet block according to the control program, it pushes the sliding block 21 to move downward, and makes the sliding block 21 and the collection bladder 22 sink back to the bottom of the water.

[0054] When the storage bladder 20 drives the sliding block 21 and the collection bladder 22 to move to the top, the collection bladder 22 is located above the floating block 1; when the sliding block 21 and the collection bladder 22 move downward, the collection bladder 22 first contacts the floating block 1. When the sliding block 21 continues to move downward, the collection bladder 22 rotates around the sliding block 21, so that the side of the collection bladder 22 close to the sliding rod 2 faces the outside, the upper and lower sides of the collection bladder 22 are turned over, and the hook 71 on the collection bladder 22 contacts the floating block 1. When the sliding block 21 continues to move downward, the sliding plate 7 is driven to slide through the restriction of the hook 71, so that the discharge chute is opened to facilitate the waterborne floating objects inside the turned-over collection bladder 22 to fall to the outside; by means of sunlight exposure, the bacteria and parasites in the waterborne floating objects are killed, and at the same time, it is beneficial to the decomposition and transformation of the organic matter in the waterborne floating objects, releasing nutrient elements and energy, which is beneficial to plant growth, facilitating the establishment of an ecological floating island, and improving the efficiency of river environmental governance.

[0055] Embodiment 2:

[0056] The difference from Embodiment 1 is that a plurality of hollow layers are formed on the floating block 1, a water filtration layer 3 stacked with the floating block 1 is arranged inside the hollow layer, and a plurality of planting areas (not shown in the figure) for planting aquatic plants are arranged on the water filtration layer 3, and the planting areas are located on both sides of the water filtration layer 3; the water filtration layer 3 includes, but is not limited to, one or more of a filter screen, a foam layer, a charcoal layer, and a gravel layer. A baffle 31 is slidably fitted inside the hollow layer, a clamping block 32 is rotatably fitted on one side of the baffle 31 away from the stacking channel 11, and a torsion spring (not shown in the figure) is rotatably fitted on the clamping block 32.

[0057] The specific implementation process is as follows: A multi-layer filtering mechanism is formed through the water filtering layer 3 to reduce water floating substances such as algae, organic matter, and sediment in the river water flowing back, providing a nutritional basis for the growth of crops on the ecological floating island, and at the same time facilitating the river water to flow back into the river channel to achieve cyclic filtration.

[0058] Meanwhile, the hollow layer is divided by the baffle 31 into two chambers; during the continuous accumulation of water floating substances on the baffle 31, the weight of the water floating substances is utilized to overcome the restriction of the clamping block 32, so that the water floating substances accumulated on the baffle 31 are transported downward. Compared with not setting the baffle 31, the continuous accumulation of water floating substances at the bottom of the hollow layer is reduced to achieve the uniform laying of water floating substances.

[0059] Embodiment 3:

[0060] The difference from Embodiment 2 is that the water filtering layer 3 is circumferentially arranged around the accumulation channel 11, and a return pipe 42 is also connected below the water filtering layer 3. The return pipe 42 is connected to a water outlet 41, and the water outlets 41 are circumferentially arranged around the floating block 1, and adjacent water outlets 41 are connected;

[0061] Below each water outlet 41, a fan blade 4 is provided, and the fan blade 4 is rotationally matched with the floating block 1;

[0062] A solenoid valve is connected inside the water outlet 41, and the solenoid valve is electrically connected to a communication module for establishing a communication connection with the outside

[0063] The specific implementation process is as follows: During the filtering process of the water filtering layer 3, the filtered water flow is collected through the return pipe 42, and when it is discharged through the water outlet 41, the impact force on the fan blade 4 is used to push the floating block 1 to move slowly in the opposite direction; at the same time, the opening and closing of the solenoid valve are controlled through the communication module, so that the management personnel can adjust the position of the floating block 1 on the shore, so that the floating block 1 can manage the river channel according to the set route.

[0064] Embodiment 4:

[0065] The difference from Embodiment 3 is that the blower 8 is also electrically connected to a storage battery 82. The storage battery 82 is located inside the floating block 1, and the storage battery 82 is electrically connected to a solar energy component (not shown in the figure) for solar power generation. The solar energy component is located between adjacent water filtering layers 3.

[0066] The specific implementation process is as follows: The solar energy component is used to collect the unobstructed light on the water surface to achieve the reuse of resources and continuously supplement the power of the storage battery 82 to extend the service time of the device.

[0067] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
