Specific implementation mode
As shown in Figure 1, this compound pipeline complex pipeline, including tube body 13, there are one cavity 11, cavitys 11 for the inner end setting of tube body 13
Top setting there are one supporting case 3, there are one arc-shaped concave 2, the bottom of supporting case 3 is arranged for the lower face setting of supporting case 3
There is an intermediate tube 12, there are one drainage channel 9, top and the upper end supporting cases 3 of intermediate tube 12 for the intermediate tool of intermediate tube 12
The contact engagement of arc-shaped concave 2;
The bottom setting of intermediate tube 12 is there are one elastic supporting member for supporting optical member, and intermediate tube 12 is by the elastic supporting member for supporting optical member of bottom towards branch
It supports box 3 bottom surface to compress, the both sides of elastic supporting member for supporting optical member are buckled into respectively in the card slot of inboard wall of tube body, and it is solid to squeeze into waterproof glue sticking
It is fixed.
In the present embodiment, elastic supporting member for supporting optical member includes two interconnecting pieces 14, flexible support portion 6 and main part 7, resilient support
Portion 6 is set to the top of main part 7, and the bottom of intermediate tube 12 is buckled into flexible support portion 6, and interconnecting piece 14 is set to main part
One end of 7 both sides, interconnecting piece 14 buckles into the card slot of 13 inner wall of tube body, and there are one mute rows for setting among main part 7
Water cavity 8 forms an adapter cavity 21, passes through one between mute drainage cavity 8 and adapter cavity 21 between interconnecting piece 14 and intermediate tube 12
A above leak aperture 5 is connected, and leak aperture 5 is opened in the clear area of flexible support portion 6.
In the present embodiment, in order to enable intermediate tube to be compressed towards upper end, spy integrally uses elastic supporting member for supporting optical member
Elastic rubber material is made, and such intermediate tube can be compressed towards the arc-shaped concave of supporting case bottom always.
Wherein, there are one water chambers 16,16 bottom surface of water chamber to open up one in linear type arrangement for the intermediate tool of supporting case 3
The the first above jack is inserted into a conduit 17 in each first jack, and the intermediate tube upper surface of the first jack of face is provided with
Corresponding second jack, 17 one end of conduit are inserted in water chamber 16, the other end pass through the second jack and with inside intermediate tube 12
Drainage channel 9 be connected, the water outlet end of conduit 17 is set to the top of conduit 17, top delivery port end and the water outlet of conduit 17
16 top surface of chamber is in sealing contact, and conduit 17 and the contact surface of the second jack are adhesively fixed by marine glue, 17 outer wall of conduit and first
Jack inner wall sealing contacts, by draining the connection conducting of aperture 15 between water chamber 16 and adapter cavity 21.As shown in Fig. 2, conduit
Water outlet end be provided with a silicagel pad 18, silicagel pad 18 is contacted with the top surface of water chamber 16, setting water outlet among silicagel pad 18
Aperture 19.Since tube at one end and intermediate tube are fixed, and intermediate tube is contacted with the arc-shaped concave of supporting case bottom always so that is led
The silicagel pad of the water outlet end of pipe is in sealing contact with the top surface of water chamber always, at this time the ostium excurrens sealing among silicagel pad,
Can not be discharged, amount of rainfall hour can using the drainage channel among intermediate tube carry out proper drainage, due to intermediate tube not with pipe
Body contacts, therefore when rainfall is smaller, do not rain water noise at all.
In the present embodiment, the outer wall of intermediate tube 12 is provided with more than one guiding gutter 4, and guiding gutter 4 is located at adapter cavity 21
Interior, when amount of rainfall is very big, the displacement in intermediate tube can also increase, and the weight of whole at this time intermediate tube increases, intermediate in this way
Pipe can push the elastic supporting member for supporting optical member of bottom so that elastic supporting member for supporting optical member also declines, and since intermediate tube declines, sealing originally is led
Pipe water outlet end is opened, and the rainwater in intermediate tube can pass through the water outlet of catheter output end to exit into supporting case at this time
Between water chamber in, then by the draining aperture of water chamber both sides water is exited into adapter cavity, rainwater first can be in
Between the outer wall of pipe enter in guiding gutter, drained using guiding gutter, the amount of rainfall overflowed at this time is little, when the rainwater of spilling
When very much, these rainwater can flow into the bottom surface of adapter cavity, and be entered in mute drainage cavity across leak aperture, and due to quiet
Sound drainage cavity is also hanging structure, therefore will not generate vibration to external tube body when realizing Overflow drainage, therefore is had
There are extraordinary damping effect and muting function, tube wall not to vibrate, the case where vibrating noise would not also occur.
The beneficial effects of the invention are as follows:1, pipeline of the invention realizes proper drainage using an intermediate tube, works as intermediate tube
It, can be by way of increasing own wt, to make elastic supporting member for supporting optical member decline, so that in intermediate tube when internal drainage amount is big
Water leak out, realize mute draining;
2, by hanging adapter cavity come mute draining, meet it is mute under the premise of and can guarantee displacement, due to entirety
Hanging draining, therefore when displacement is very big, will not occur the vibration between tube wall and building wall because of pipe vibration
The noise of appearance.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection domain should be determined by the scope of protection defined in the claims.
