It connects；
Liner 18, is set between track 14 and Leak-tight liner siding 12, when magnet 10 and Leak-tight liner siding 12 adsorb, lining
The side of pad 18 is bonded with track 14, and the other side is bonded with Leak-tight liner siding 12；And
Gas hood 22, two sides pass through gas hood fixation member 20 respectively and are fixed on two tracks 14.
Please continue to refer to shown in Fig. 1 and Fig. 2, magnet 10 be provided with it is multiple, to the weldering between two pieces of Leak-tight liner sidings 12
When seam 16 is welded, one end of magnet 10 is adsorbed on Leak-tight liner siding 12, when welding completion, magnet 10 can be removed reality
The dismounting of existing whole device.Magnet 10 can be fixedly connected by welding with track 14, can also be arranged by the edge in track 14
Then fluting is bolted in the fluting of magnet insertion track 14.
It please referring to shown in Fig. 3 and Fig. 4, it is preferable that magnet 10 is switching magnet, its working principle is that:
1) magnet contactor shell is two pieces of magnetizers 100, and centre is separated with non-magnetic brass sheet 102, and inside is one
Rotatable magnet 104, the diametrically opposite pole N, S of magnet 104, when magnet 104 rotate to middle position (magnet open/
Decontrol), when the magnetic line of force forms closed circuit in two pieces of magnetizers 100 respectively, magnet 10 can be taken away；
2) after being rotated by 90 °, the pole N, S is respectively toward to two pieces of magnetizers 100, and the magnetic line of force is from N pole to magnetizer 100 through Leak-tight liner
Siding 12 arrives the pole S to another piece of magnetizer 100, forms magnetic line of force closure, can be adsorbed onto (magnet on Leak-tight liner siding 12
Close/be attracted), and there is enough suction between magnet 10 and Leak-tight liner siding 12, whole device can be prevented in the welding process
It is fallen from Leak-tight liner siding 12, plays the role of radix saposhnikoviae protection.
Track 14 is flexible rail, preferably aluminium alloy flexible rail, can be rolled over according to the shape of Leak-tight liner siding 12
Curved, track 14 is strip structure, has certain thickness and width, is provided with two, and two tracks can be identical, can also be different,
When in use, the two sides of weld seam 16 are separately positioned on.In the shown embodiment, multiple open is provided on each track 14
Slot, and will be fixed in multiple magnet 10 insertion fluting, and pass through the suction-operated of magnet 10, track 14 is absorbed and fixed at
Leak-tight liner siding 12 can be adapted for the weld seam of axial zone radian in containment steel liner by the way that flexible rail 14 is arranged.
Weld seam 16 usually has vertical weld seam and cross weld, and when for vertical weld seam, two tracks 14 are vertically arranged, and with
Weld seam 16 is substantially parallel, and when for cross weld, the laterally setting of two tracks 14 is also substantially parallel with weld seam 16.
Liner 18 is rubber packing, and there are two settings, is used cooperatively with two tracks 14, is adsorbed on steel lining in magnet 10
When on backing plate 12, the side of each liner 18 is bonded with the bottom of a track 14, and the other side is fitted in Leak-tight liner siding
On 12, sealing function is played, fitting only indicates face and face contact herein, do not represent and be fixedly connected, it can be achieved that disassembled and assembled freely.Due to
Leak-tight liner siding 12 may be the structure with radian, and liner 18 can be bent according to the radian of Leak-tight liner siding 12, can edge
Length direction bending, can also bend in the width direction, can be configured as the structure with radian.In the shown embodiment, it serves as a contrast
Pad 18 is the rubber packing of cube structure, when being bonded with track 14 and Leak-tight liner siding 12, has certain contact surface, prevents
Only gap is formed between track 14 and Leak-tight liner siding 12.
Gas hood fixation member 20 is the intermediate plate of laminated structure, is fixed on track 14, in the shown embodiment, often
At least provided with two intermediate plates on one track 14, and it is integrally formed with track 14.The first threaded hole, intermediate plate are provided on intermediate plate
Position may be provided at middle part, may also be arranged on both ends, or be arranged in other any desired positions.
Gas hood 22 is transparent flexible gas hood, preferably PVC transparent flexibility gas hood, more preferably PVC transparent flexibility gas hood, gas
The size of cover 22 can be adjusted according to the distance between two tracks 14.The contact of the two sides of gas hood 22 and track 14
The substantially seamless gap in face, because Leak-tight liner siding 12 is usually arcuate structure, when weld seam 16 is cross weld, gas hood 22 can be curved
Being converted into has radian corresponding with Leak-tight liner siding 12, and when weld seam 16 is vertical weld seam, the two sides of gas hood 22 can be
Form of straight lines.Corresponding first screw thread hole site is provided with the second threaded hole on the two sides of gas hood 22, and passes through screw or bolt
Gas hood 22 is fixed on the surface of track 14.
In order to be blocked to 22 both-side opening of gas hood, guarantees welding quality, stomata is prevented, the two of gas hood 22
Side is additionally provided with cover board (not shown go out), and cover board can be pasted on gas hood 22 by adhesive tape fixation, can also by other means with
Gas hood is fixed, and cover board can also be the plugging structure of other forms.
In the shown embodiment, when weld seam 16 is vertical weld seam, up and down the two of track 14, liner 18 and gas hood 22
The upper and lower ends all concordant, cover board is arranged in track 14, pads 18 and gas hood 22 are held, and gas hood 22 is pasted by adhesive tape fixation
On, it prevents wind to be blown into from upper and lower ends, plays windproof protective effect.When weld seam 16 is cross weld, track 14,18 and of liner
The left and right ends of gas hood 22 are all concordant, and the left and right ends of track 14, liner 18 and gas hood 22 are arranged in cover board, and solid by adhesive tape
Surely it is pasted on gas hood 22, wind is prevented to be blown into from left and right ends, play windproof protective effect.
When the Leak-tight liner siding that back of weld Windproof protective device in entire containment steel liner is arranged in 16 two sides of weld seam
After on 12, by being welded in the other side, since welding position there will not be aerial beam wind to influence, entire weld seam can be made without sky
Gap, and the root of weld can be observed by PVC transparent flexibility gas hood 22 in welding and form situation.When the welding is completed, Ke Yizhi
It connects to pull out the magnet 10 of absorption and integral demounting can be realized, in use, magnet 10 is adsorbed on Leak-tight liner siding 12 again,
Can being dismounted for multiple times without damage 12 ontology of Leak-tight liner siding.
It should be noted that can adjust the length of liner 18, track 14 and gas hood 22 when the length of weld seam 16 changes
Degree, and the number of magnet 10 and gas hood fixation member 20 is accordingly adjusted, to adapt to the demand of the weld seam 16 of different length.
Compared with the existing technology, the utility model nuclear power plant containment shell Leak-tight liner back of weld Windproof protective device have with
Lower advantageous effects:
1) by increasing back of weld wind-proof device, because of aerial beam wind shadow when can solve barrel soldering in containment steel liner
Welding defect caused by ringing；
2) whole device is adsorbed on containment steel liner backing plate 12 using magnet 10, whole device installation operation letter
It is single, convenient, it is convenient for disassembly and assembly；
3) it can be adapted for the weld seam of axial zone radian in containment steel liner using flexible rail 14；
4) transparent flexible gas hood 22 is used, forms situation convenient for observation 16 root of weld seam.
According to above-mentioned principle, the utility model can also be made appropriate changes and modifications to the above embodiments.Therefore,
The utility model is not limited to specific embodiment disclosed and described above, to some modifications and changes of the utility model
It should also be as falling into the protection scope of the claims of the present utility model.In addition, although having been used in this specification some specific
