[0003] It can be used for the circulation and purification of slightly polluted urban water bodies (rivers, lakes, etc.) and for the circulation and purification of urban water bodies (rivers, lakes, etc.) with high turbidity. Because it is installed underwater, it has gained popularity. However, precisely because it is installed underwater, its installation, dismantling, and maintenance are very complicated, causing trouble for maintenance personnel. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bottom-mounted biological filter device, which can facilitate the maintenance and disassembly of the filter module.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 4 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a submerged biological filter device, including a conveying pipe 1, a mounting frame 2, and a filter module 3. Multiple sets of branch pipes 11 are provided on one side of the conveying pipe 1. Multiple sets of mounting frame 2 and filter module 3 are provided, and they are arranged one-to-one with the branch pipes 11.

[0026] The filter module 3 can be detachably installed on the mounting bracket 2;

[0027] The mounting frame 2 has a mounting cavity 21 in the middle for mounting the filter module 3, and a limit component 4 is provided in the mounting cavity 21.

[0028] On opposite sides of the mounting bracket 2, there are mounting parts 5 that cooperate with the branch pipe 11 and connecting parts 6 that connect to the lake bottom.

[0029] The design of this utility model allows for the detachable connection of the filter module 3 and the mounting bracket 2. When maintenance or disassembly is required, only the filter module 3 needs to be disassembled, which is convenient for operation. Meanwhile, the mounting bracket 2 is connected to the branch pipe 11 and the lake bottom for a long time without the need for disassembly.

[0030] like Figure 1 As shown, when one end of the filter module 3 slides down along the inner wall of the mounting cavity 21, and the limiting component 4 limits and fixes the filter module 3, the through hole on the filter module 3 corresponds to the branch pipe 11, and then it can be sealed and fixed by the flange. The two are easy to disassemble and assemble.

[0031] The present invention is further configured such that: the limiting component 4 includes a limiting rod 41 and a limiting spring 42, the mounting bracket 2 is provided with a limiting groove 22, and the limiting rod 41 is slidably connected to the limiting groove 22 through the limiting spring 42;

[0032] The filter module 3 has a limiting hole 31 on its outer side that cooperates with the limiting rod 41.

[0033] like Figure 4 As shown, when the filter module is installed into the mounting cavity 21, the limiting rod 41 is inserted into the limiting hole 31, thus limiting the position of the limiting rod 41.

[0034] The present invention is further configured such that: the limiting rod 41 includes a limiting head 43 facing the mounting cavity 21, and the upper end surface of the limiting head 43 is provided with a guide slope 431. With this structure, when the filter module is installed into the mounting cavity 21, it first abuts against the guide slope 431, thereby pushing the limiting rod 41 to slide within the limiting groove 22 and compressing the limiting spring 42.

[0035] When the limiting hole 31 is aligned with the limiting rod 41, the limiting head 43 can be inserted into the limiting hole 31 to form a limit.

[0036] The present invention is further configured such that: the limiting groove 22 passes through the mounting bracket 2, and the limiting rod 41 includes a limiting block 44 facing away from the mounting cavity 21, the diameter and length of the limiting block being larger than that of the limiting groove 22.

[0037] The structure is designed such that when the limiting component 4 needs to be released, the limiting block can be pulled outward, thereby separating the limiting head 43 from the limiting hole 31.

[0038] When completely separated, a limiting block can be hung on the outside of the limiting rod 41 to restrict the return movement of the limiting rod 41 (the limiting blocks abut against the limiting block and the mounting bracket 2 respectively), which facilitates the subsequent disassembly and assembly of the filter module.

[0039] The present invention is further configured such that: a pipe hole 51 is provided at the mounting part 5, and the pipe hole 51 extends downward through the mounting bracket 2. The lower port diameter of the pipe hole 51 is larger than the upper port diameter, and gradually decreases from bottom to top.

[0040] like Figure 3 As shown, the design of the pipe hole 51 with this size allows the mounting part 5 to be installed to the branch pipe 11 through the mounting hole, and as the mounting bracket 2 is continuously installed downwards, it can help adjust the angle of the mounting bracket 2.

[0041] The present invention is further configured such that: the connecting part 6 includes a connecting end face 61 and a connector 62, the connector 62 is provided in multiple sets and can be detachably installed on the connecting end face 61, and the connector 62 includes a connector head 621 and a piercing rod 622.

[0042] Multiple sets of thin film holes 611 are provided on the connecting end face 61.

[0043] The design of this structure allows the mounting part 5 to be aligned and then inserted into the lake bottom through the connecting piece 62 via the membrane hole 611 to form a fixed structure. In addition, other fixing structures can be provided on the other two sides of the mounting frame 2. The fixing structure adopts the existing structure according to the specific situation, which will not be described in detail here.

[0044] The present invention is further configured such that: a connecting groove 612 is provided on the connecting end face 61 for the connector 621 to be inserted.

[0045] The design of this structure allows the connector 621 to be fitted together via the connecting groove 612, thereby improving the connection strength between the two.

[0046] Preferably, the connector 621 can be made of an elastic material to form an interference fit with the connecting groove 612, thereby improving the installation strength.

[0047] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
