Description

Technical Field

[0001] The utility model relates to the technical field of curtain-type membrane assembly installation, in particular to a curtain-type membrane assembly water collecting pipe fixing structure. Background Art

[0002] The water collecting pipe of the curtain membrane module is usually connected to the water production joint at one end, and the other end is directly fixed to the angle iron through a U-shaped clip, a nut and a gasket. Since the water collecting pipe and the U-shaped clip are both circular in cross-section, there are multiple line contacts between the two during the tightening process, and there is also line contact between the water collecting pipe and the angle iron. The material of the water collecting pipe is generally ABS material. During the fixing process, stress concentration is often caused due to line contact, which leads to the problem of stress whitening of the water collecting pipe, reducing the service life of the water collecting pipe. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a curtain-type membrane assembly water collecting pipe fixing structure, and the technical solution it adopts is: a curtain-type membrane assembly water collecting pipe fixing structure, which includes a water collecting pipe, a U-shaped clip, a nut, a gasket and an angle iron with a mounting hole, and is characterized in that: the U-shaped clip includes a card body and a claw, the card body is a sheet steel structure, the claw is a round steel structure with a thread, and the contact part between the water collecting pipe and the U-shaped clip card body, and the contact part between the water collecting pipe and the angle iron are all arranged as a plane structure.

[0004] The beneficial effect of the utility model is that since the U-shaped clip body is a sheet steel structure, and the contact parts between the water collecting pipe and the U-shaped clip body, and the contact parts between the water collecting pipe and the angle iron are all arranged as planar structures, so during the tightening process, the water collecting pipe and the U-shaped clip body, as well as the water collecting pipe and the angle iron are all in planar contact, it is not easy to generate stress concentration, and thus stress whitening of the water collecting pipe will not occur, so that the life of the water collecting pipe will not be negatively affected.

[0007] The present invention is further described below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0008] See also Figure 1 , Figure 2A curtain membrane assembly water collecting pipe fixing structure, comprising a water collecting pipe 1, a U-shaped clip 2, a nut 5, a gasket 4 and an angle iron 3 with a mounting hole, characterized in that: the U-shaped clip comprises a card body 21 and a claw 22, the card body 21 is a sheet steel structure, the claw 22 is a round steel structure with a thread, and the contact part between the water collecting pipe 3 and the U-shaped clip card body 21, and the contact part between the water collecting pipe 1 and the angle iron 3 are all set as a plane structure. Since the U-shaped clip card body 21 is a sheet steel structure, and the contact part between the water collecting pipe 1 and the U-shaped clip card body 21, and the contact part between the water collecting pipe 1 and the angle iron 3 are all set as a plane structure, in this way, during the fastening process, the water collecting pipe 1 and the U-shaped clip card body 21, and the water collecting pipe 1 and the angle iron 3 are all in plane contact, which is not easy to generate stress concentration, and thus the water collecting pipe stress whitening phenomenon will not occur, so that the life of the water collecting pipe will not be negatively affected.
