A feeding port is provided on the side of the collection assembly cylinder 23 facing the feeding wheel 24, and the feeding wheel 24 actively pushes the floating objects into the collection assembly cylinder 23 for collection, which is used for the rapid treatment of river areas with floating garbage.

[0033] The artificial fish nest mechanism 3 described in this embodiment includes a first bracket 31 detachably connected to the floating support body 1, and the first bracket serves as the main supporting structure of the artificial fish nest mechanism.

The above two management methods can be carried out simultaneously or used separately. The two management methods are dual-track and parallel, which enriches the river water environment management methods, improves the management efficiency, and has high practical value.

[0035] Example 2: Figure 2As shown, a comprehensive restoration and management device for river ecological environment is further optimized on the basis of Example 1. The collection combination cylinder 23 described in this embodiment includes an outer cylinder 2301 and an inner net cylinder 2302 that are snap-fitted. When the amount of garbage in the inner net cylinder reaches a certain amount, the snap-fit ​​design is convenient for the rapid replacement of the inner net cylinder. The outer cylinder 2301 is fixedly connected to the U-shaped seat 22, and the U-shaped seat 22 is hinged to the connecting frame 21. Specifically, a pin shaft can be used to realize the hinge connection between the ear seat on the outer wall of the U-shaped seat 22 and the ear seat on the connecting frame 21, so that the outer cylinder can swing at a certain angle relative to the U-shaped seat to adapt to the fluctuating water surface, so that floating objects can enter the collection combination cylinder more accurately.

The inner wall of the inner net cylinder 2302 is provided with a baffle plate 2304 corresponding to the feed inlet. The baffle plate can be pushed open by the impact force of the floating objects and water outside under the action of the feeding wheel, and the garbage in the inner net cylinder cannot flow out of the cylinder, so the baffle plate plays a role similar to a one-way valve to prevent the floating objects in the cylinder from overflowing. The bottom of the outer cylinder 2301 is provided with a water outlet to facilitate the rapid outflow of water in the outer cylinder. The top of the outer cylinder 2301 and one side close to the U-shaped seat 22 are provided with an arc baffle plate 2305; it blocks the floating objects pushed by the feeding wheel 24, so that the maximum amount of them can enter the inner net cylinder. The mesh design of the inner net cylinder reduces the mass of the inner cylinder and plays a filtering role to efficiently collect floating garbage.

[0036] Specifically, if Figure 3 As shown, the inner net cylinder 2302 includes a mesh ring cylinder 2302-1, which is sleeved with the outer cylinder body, and the feed port on the inner cylinder is opened on the side wall of the mesh ring cylinder. The top of the mesh ring cylinder 2302-1 is provided with an inclined top plate 2302-2, and the lower side of the top plate 2302-2 is provided with an annular opening 2302-3, so that the top floating objects or duckweed can flow smoothly into the inner net cylinder, and the high side of the top plate 2302-2 faces the arc baffle 2305 and fits with the arc baffle, so that the floating objects blocked by the baffle can smoothly enter the annular opening. A flexible net bag 2302-4 is provided at the bottom of the mesh ring tube 2302-1. The flexible net bag is light in weight and large in capacity, and can further increase the amount of floating garbage collected. A fastener 2302-5 is provided on the upper part of the mesh ring tube 2302-1 to match the outer cylinder 2301, so as to realize the snap-fitting of the inner net tube and the outer cylinder. The fastener can adopt a parent-child lock or a block structure, and the block is snap-fitted with a slot provided on the outer cylinder. The snap-fitting of the inner net tube and the outer cylinder facilitates the quick extraction of the inner net tube from the outer cylinder, and facilitates the cleaning of floating garbage.

It should be noted that the length-adjustable structure can adopt a telescopic oil cylinder, or a plurality of positioning holes in a row are opened on the hollow arm column and the connecting arm, and then the pin shaft is used to cooperate with different positioning holes to achieve the adjustment of the extension length of the connecting arm, which has been adapted to the operation area of ​​​​moving floating objects in different waters. In this embodiment, a feeding wheel 24 is rotatably arranged at the lower part of the connecting arm 26, and the wheel shaft of the feeding wheel 24 is rotatably connected to the connecting arm through a bearing, and the wheel shaft of the feeding wheel 24 is connected to a waterproof motor 27 arranged on the upper part of the connecting arm 26.

As a preference, the blades of the feeding wheel 24 are arc-shaped blades, which have a gathering effect and are used to collect floating objects. The arc-shaped blades are evenly distributed with water filtering holes to reduce resistance. During operation, the two feeding wheels 24 rotate in opposite directions to form a two-sided digging structure, which collects and pushes the floating garbage into the collection barrel to achieve rapid and active collection.
