[0006] The first connector has a first external thread at its first end and a spherical connecting part at its second end;

[0007] The second connector has a second external thread at its first end and a spherical groove at its second end that is adapted to the spherical connecting part. The spherical connecting part is movably inserted into the spherical groove so that the included angle between the axis lines of the first connector and the second connector can be changed, and the outer wall of the spherical connecting part is sealed to the inner wall of the spherical groove.

[0008] The mounting bracket has a third connector on its first side and a fourth connector on its second side. The third connector has a first internal thread that matches the first external thread, and the fourth connector has a second internal thread that matches the second external thread.

[0009] Furthermore, the connection structure also includes a connecting element, wherein the first end of the connecting element is provided with a third internal thread adapted to the first external thread, and the second end is provided with a fourth internal thread adapted to the second external thread.

[0010] Furthermore, the connecting element is a telescopic structure so that its length can be adjusted.

[0011] Furthermore, the third connector and the fourth connector are movably connected to the mounting bracket, so that the third connector and the fourth connector can not only move along their own axis, but also rotate around their own axis.

[0012] Furthermore, the pitch structures of the first external thread and the second external thread are the same.

[0013] Furthermore, it also includes a plug, which is provided with a fifth external thread adapted to the first internal thread and / or a sixth external thread adapted to the second internal thread.

[0014] The beneficial effects of this utility model are:

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0029] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] like Figure 2-8 As shown, this utility model provides a modular MBR membrane module, including multiple MBR membrane units and a connection structure for connecting two adjacent MBR membrane units.

[0034] The MBR membrane unit includes a mounting frame 110 and an MBR membrane 120 disposed on the mounting frame 110.

[0035] The connection structure includes a connection device, which includes a first connector 210 and a second connector 220.

[0036] The first connector 210 has a first external thread 212 at its first end and a spherical connecting portion 211 at its second end. The second connector 220 has a second external thread 222 at its first end and a spherical groove 221 at its second end that matches the spherical connecting portion 211. The spherical connecting portion 211 is movably inserted into the spherical groove 221, allowing the included angle between the axes of the first connector 210 and the second connector 220 to change, and the outer wall of the spherical connecting portion 211 is sealed to the inner wall of the spherical groove 221. The mounting bracket 110 has a third connector 130 on its first side and a corresponding fourth connector 140 on its second side. The third connector 130 has a first internal thread 131 that matches the first external thread 212, and the fourth connector 140 has a second internal thread 141 that matches the second external thread 222.

[0037] During operation, by changing the angle between the first connector 210 and the second connector 220, the extension direction of multiple MBR membrane modules during assembly can be changed, thereby achieving the purpose of adapting to irregular or arc-shaped water tanks.

[0038] like Figure 4 and Figure 6 As shown, in this embodiment, the connection structure further includes a connecting element 230. The first end of the connecting element 230 is provided with a third internal thread adapted to the first external thread 212, and the second end is provided with a fourth internal thread adapted to the second external thread 222. During assembly, the number of connecting devices between two adjacent MBR membrane units can be changed to meet the assembly requirements. For example, in an arc-shaped water tank, the inner diameter will inevitably be smaller than the outer diameter. During assembly, the number of connecting elements 230 between two adjacent MBR membrane units on the outer side can be increased to meet the assembly requirements, thereby further improving its versatility.

[0039] Preferably, the connecting element 230 is a telescopic structure, allowing its length to be adjusted. During operation, adjusting the length of the connecting element 230 allows for fine-tuning of the installation distance between two adjacent MBR membrane units, thereby further improving its versatility.

[0040] like Figure 8 As shown, the connecting element 230 includes an inner rod 231 and an outer rod 232. The outer rod 232 is coaxially sleeved on the inner rod 231, and the inner rod 231 and the outer rod 232 can move relative to each other along the axis of the connecting element 230.

[0041] like Figures 2-4As shown, in this embodiment, the third connector 130 and the fourth connector 140 are movably connected to the mounting bracket 110, allowing the third connector 130 and the fourth connector 140 to move not only along their own axis but also to rotate around their own axis. During replacement, rotating the third connector 130 and the fourth connector 140 allows them to retract. Therefore, when replacing the intermediate MBR membrane module, it is not necessary to move other membrane modules laterally, making the operation more convenient.

[0042] Preferably, the first external thread 212 and the second external thread 222 have the same pitch structure, so that the third connector 130 and the fourth connector 140 are universal, saving costs. At the same time, during assembly, there is no need to confirm the positive and negative ends of the connector, thereby improving the convenience and efficiency of assembly.

[0043] like Figures 2-4 As shown, it also includes a plug 300, which is provided with a fifth external thread adapted to the first internal thread 131 and / or a sixth external thread adapted to the second internal thread 141.

[0044] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
