Description

Technical Field

[0001] The utility model relates to the technical field of river channel management, in particular to a biological filter bed for river channel ecological management. Background Art

[0002] When conducting ecological management of urban rivers, ecological floating islands or biological filter beds are usually placed in the rivers for management. The biological filter bed is a "bed" built with a framework that allows microorganisms to gather and survive. The river is managed by microorganisms absorbing pollutants in the river water.

[0003] According to the utility model patent with announcement number: CN219885825U, a biological filter bed for ecological management of urban rivers is disclosed, which relates to the technical field of biological filter beds, and its beneficial effects are: through the setting of the operating mechanism and the filter bed, the filter bed is divided into a bed body and a movable filter plate, the movable filter plate can move and engage with the bed body, and the movable filter plate is threadedly connected with the operating mechanism through a screw. When the filter material of the filter bed needs to be replaced, the screw is moved in the threaded barrel by rotating the threaded barrel of the operating mechanism, thereby driving the movable filter plate to move up, and the filter material can be conveniently replaced by moving it up to the operating groove. After the replacement is completed, the movable filter plate can be moved down by flipping the threaded barrel until the filter element is engaged with the mounting groove on the bed body. The structure is simple and easy to operate.

[0004] Although the above technology is convenient for replacing filter materials, the biological filter bed is set in the river channel and has no protective function, which causes garbage or branches floating on the river channel to easily accumulate around the filter bed and damage the filter bed. Therefore, there are certain defects in use.

[0005] Therefore, it is necessary to provide a new river ecological management biological filter bed to solve the above technical problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a biological filter bed for river ecological management provided by the utility model; Figure 2 This is a schematic diagram of the structure of the filter bed and filter material box in the utility model; Figure 3 It is a structural schematic diagram of the interception mechanism in the utility model; Figure 4 for Figure 3 A schematic diagram of the structure at A in the middle. A biological filter bed for river ecological management, comprising a bed body 1, the inner wall of the bed body 1 is provided with a filter box 2, the inner walls of the bed body 1 and the filter box 2 are both provided with through holes 4; an interception mechanism 3, the interception mechanism 3 comprises piles 31 arranged around the bed body 1, the inner wall of the piles 31 is slidably connected with a connecting block 32, one side of the connecting block 32 is provided with an interception net 33, the top of the interception net 33 is provided with a floating ball 34, and the bottom of the interception net 33 is fixedly connected with a counterweight block 35.

[0020] It should be noted that: the filter box 2 is used to place filter materials, and the four piles 31 are fixed around the bed 1 in the river channel. Under the action of the float 34 and the counterweight block 35, the interception net 33 can float on the water surface and be fully unfolded, so as to facilitate the interception of garbage on the water surface. The intercepted garbage is cleaned by the staff. At the same time, the buoyancy of the float 34 is greater than the weight of the counterweight block 35. Therefore, when the water level rises, the interception net 33 can automatically follow the water level rise through the float 34 and the connecting block 32, thereby improving the efficiency of garbage interception.

[0021] In the specific implementation process, Figure 1 , Figure 3 and Figure 4 As shown, the interception mechanism 3 further includes a limit block 36 fixed to one side of the connection block 32 , and a limit groove 37 is provided on the inner wall of the pile column 31 , and the limit block 36 is slidably connected to the limit groove 37 .

[0022] It should be noted that when the water level rises, the float 34 will drive the interception net 33 to move, so that the connection block 32 can drive the limit block 36 to move, and the limit block 36 moves through the limit groove 37, which can improve the stability of the interception net 33 when moving.

[0023] refer to Figure 1 and Figure 2 As shown, the inner wall of the bed body 1 is provided with mounting grooves 5, and the number of the mounting grooves 5 is four.

[0024] A mounting block 6 used in conjunction with the mounting groove 5 is fixedly connected to one side of the filter box 2 , and a handle 7 is fixedly connected to the top of the filter box 2 .

[0025] It should be noted that: by providing a handle 7, it is convenient to take out the filter box 2 from the bed 1, so as to facilitate the replacement of the filter material in the filter box 2. When the filter material in the filter box 2 needs to be replaced, it is only necessary to pull the handle 7 to make the filter box 2 drive the mounting block 6 to move and separate it from the mounting groove 5, so that the filter box 2 can be taken out from the bed 1, which is convenient for replacing the filter material. The filter material is divided into microbial filter material and limestone pyrite filter material. The total phosphorus and total nitrogen in the river water can be eliminated through the filter material.

[0026] The working principle of a biological filter bed for river ecological management provided by the utility model is as follows:

[0027] When in use, four piles 31 are fixed around the bed 1 in the river channel. Through the float 34 and the counterweight block 35, the interception net 33 can float on the water surface and be fully deployed, so as to facilitate the interception of garbage on the water surface. When the water level rises, the float 34 can make the interception net 33 automatically rise with the water level, thereby improving the efficiency of intercepting garbage.
