Sluice gate of the prior art is all all-in-one-piece, different pressurized-water nuclear power station, and size is different.With wide core M310 heap-type for reference: 6.26 × 9.1 × 0.5m (wide × high × thick), weight is about 16t.Because monolithic sluice gate volume is large, quality weight, use very inconvenience, somely be stored in reactor building, a lot of space can be occupied again, if transported the equipment gate that be difficult to by reactor building because its volume is large while that reactor building transporting again inconvenience because its quality is heavy.
Summary of the invention
The utility model, according to the deficiencies in the prior art, proposes a kind of sluice gate of segmented, and easy to use, sealing is high.
The utility model provides a kind of sluice gate for pressurized-water nuclear power station refuelling pool, comprise fixed part and stop part, described fixed part is the frame construction be symmetrically set for a pair, described frame construction has the relative U-shaped gathering sill of opening each other, and the inwall of described gathering sill is provided with projection; Described stop part is made up of multiple rectangular-shaped blocking unit, at the top of described blocking unit, there is boss portion, have the depressed part corresponding with described boss portion in the bottom of described blocking unit, the position near top on the external surface of described blocking unit also has the location division be oppositely arranged with the projection of described gathering sill; And multiple described blocking unit is plugged in described gathering sill successively vertically, the boss portion of the described blocking unit of below be inserted into described blocking unit in top depressed part in thus by described blocking unit between be interconnected, the projection of described gathering sill and the location division of described blocking unit mutually against thus make described blocking unit be close to the inwall of described gathering sill.
Preferably, between described blocking unit, also there is horizontal sealing.
Preferably, between described blocking unit and described gathering sill, also there is vertical sealing.
Preferably, described location division is designed to offset pattern, non-interference each other.
Compared with prior art, the utility model has following beneficial effect:
1, whole sluice gate is divided into multistage, and after sluice gate segmentation, each section all can be passed through reactor building equipment gate smoothly.After arriving reactor building, ring hangs handling and the splicing that can realize each section easily.After being used to complete, utilizing ring to hang can take apart each section again, and transports reactor building storage.
2, adjacent upper and lower two intersegmental without the need to special linkage, only need by blocking unit depressed part and boss portion can realize upper-lower seal, install, disassemble conveniently.
3, have employed horizontal sealing and vertical sealing, utilize the back pressure of equipment self-weight and one-sided water to realize sealing, good sealing effect.
4, have employed projection and location division positions, guarantee each section can in place smoothly and when reactor regional water does not arrange each section of sluice gate be close to frame construction.
5, the design concept of this refuelling pool sluice gate, form of structure etc., go for AP series nuclear power station refuelling pool sluice gate completely, also can be applicable to other sluice gates needing segment design simultaneously.

Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of sluice gate for pressurized-water nuclear power station refuelling pool, comprise fixed part 1 and stop part 2, described fixed part 1 is the frame construction be symmetrically set for a pair, described frame construction has the relative U-shaped gathering sill 11 of opening each other, and the inwall of described gathering sill 11 is provided with projection 111.
Described stop part 2 is made up of multiple rectangular-shaped blocking unit 21, at the top of described blocking unit, there is boss portion 211, have the depressed part 212 corresponding with described boss portion in the bottom of described blocking unit, the position near top on the external surface of described blocking unit also has the location division 213 be oppositely arranged with the projection of described gathering sill.
