Preferably, the inner wall of the outer tube 22 is closely attached to the outer wall of the inner tube 21.

The technical solution of the present invention will be described in detail with reference to the following examples.

Example one

As shown in fig. 1 to 5, each supporting wall 1 includes a first supporting plate 11 and a second supporting plate 12, the first supporting plate 11 has a plurality of first fixing holes, the second supporting plate 12 is parallel to and spaced from the first supporting plate 11, a gap between the second supporting plate 12 and the first supporting plate 11 is the communicating cavity, the second supporting plate 12 has a plurality of second fixing holes, the second fixing holes are arranged in one-to-one correspondence with the first fixing holes, and the second fixing holes are arranged coaxially with the corresponding first fixing holes.

The pipeline assembly 2 is arranged corresponding to the first fixing holes one by one and comprises an inner pipe 21, an outer pipe 22 and at least one sealing ring 23, the inner pipe 21 coaxially penetrates through the corresponding fixing holes, the inner pipe 21 coaxially penetrates through the first fixing hole and the second fixing hole, and the outer wall of the inner pipe 21 is matched with the inner wall of the second fixing hole; the outer tube 22 is sleeved on the inner tube 21 and inserted into the corresponding first fixing hole, the inner wall of the outer tube 22 is inwards recessed to form a plurality of drainage grooves 2a, the drainage grooves 2a are arranged along the axial direction of the outer tube 22, the drainage grooves 2a are evenly distributed along the circumferential direction of the outer tube 22, and the drainage grooves 2a are communicated with the communication cavity.

Preferably, the drainage groove is long-strip-shaped, the cross section of the drainage groove is square, and four to twelve drainage grooves 2a are formed in each outer tube 22; preferably, each outer tube 22 is provided with ten drainage grooves 2a, eight drainage grooves 2a are uniformly distributed along the circumferential direction of the outer tube 22, and the drainage grooves 2a penetrate through the outer tube 22 along the axial direction of the outer tube 22.

Preferably, the outer tube 22 passes through the first fixing hole, and the distance between the end surface of one end of the outer tube 22 passing through the first fixing hole and the first support plate 11 is one centimeter.

By passing the outer tube 22 through the first fixing hole, the leaked liquid flows out from both ends of the outer tube 22 through the drainage groove 2a, and the outflow point is located between the first support plate 11 and the second support plate 12, so that the liquid flowing to the space between the outer tube 22 and the inner wall of the first fixing hole can be effectively reduced.
